SLEEP ASSIST DEVICE FOR SEATED PERSONS

Abstract

A sleep assist device for use by a seated person consisting of a box-like three-sided pylon 10 that when placed on top of a seated person's lap, or on top of a suitable support surface, provides him/her with an adequate raised support for his/her head and also allows the seated person to embrace (to hug) said box-like three-sided pylon 10 by positioning his/her arms and hands over and around an embraceable volume 38 in a cozy and comfortable resting posture that, indeed, is conducive to relaxation and/or sleep. Meanwhile, a vertical back panel 14 (part of said embraceable volume 38) may contact said seated person's chest. The box-like three-sided pylon 10 when folded up for storage or transport is relatively small and lightweight (comparable in size to a periodical magazine) allowing a user to conveniently place it into: an airplane's seat back pocket, carry-on luggage, a ladies' handbag, a business briefcase or a suitcase, among others. This sleep assist device for a seated person is likely to be readily accepted by a relatively large percentage of passengers traveling by airplane, bus, train and/or in an automobile's rear seat, as well as by persons wishing to nap at their workplace, at home, while waiting at a hospital or office, or during camping or at a beach outing and, furthermore, by ailing persons confined to nursing homes that need to be seated in wheelchairs or sofas during extended periods of time. In addition, said box-like three-sided pylon 10 provides a novel, useful and unobvious medium to display: advertisements, the subject matter required on airline passenger's safety card, or business logos since its visible surfaces can be printed utilizing any of the available methods employed by the packaging industry, or may also have relevant labels affixed to its visible surfaces.

DESCRIPTION OF SPECIFIC EMBODIMENTS

[0086] The following description intends to teach persons skilled in the art to manufacture and make use of the embodiments disclosed herein. A variety of obvious modifications to the disclosed embodiments will be readily apparent to persons skilled in the art, and the general principles defined hereinafter may be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Accordingly, the present disclosure is not limited to the embodiments shown, but is to be in agreement to the widest scope dependable with the principles and features disclosed.

[0087] It is helpful to understand the basic structural components to be comprised by all embodiments as well as their mode of utilization in order to appreciate the scope, the novelty, the usefulness and the non-obvious nature of this disclosure.

[0088] The first embodiment pertaining to disclosed “A Sleep Assist Device For Seated Persons” is shown on FIGS. 1 through 4. This embodiment is depicted at its deployed configuration, namely a ready for utilization mode. The embodiment's folded configuration, suitable for stowing or transport, will be described hereinafter when referring to FIGS. 5. Said first embodiment comprises a box-like three-sided pylon 10 that includes a base panel 12, a vertical back panel 14, a pair of vertical front panels 16-16, a top panel 18, an elastic band 20, a pair of hookup ends 22-22 and a fastening means 24.

[0089] The base panel 12 connects to the vertical back panel 14 thru a base bendable edge 26, the top panel 18 connects to the vertical back panel 14 thru a top bendable edge 28 and each vertical front panel 16 connects to the vertical back panel 14 thru a side bendable edge 30.

[0090] Each vertical front panel 16 includes a vertical free rim 32. When the box-like three-sided pylon 10 is at its deployed configuration (the ready for utilization mode) said pair of vertical front panels 16-16 contact each other along their vertical free rims 32-32. During utilization, to prevent separation of said pair of vertical free rims 32-32, said fastening means 24 are employed to holds together said pair of vertical front panels 16-16.

[0091] Holding together the pair of vertical front panels 16-16 prevents any unintended folding of the box-like three-sided pylon 10 during utilization.

[0092] The ends of said elastic band 20 is simultaneously connected to the base panel 12 and the top panel 18 via a pair of hookup ends 22-22. The elastic band 20 is not viewable at full length on most figures because it is enclosed inside the hollow three-sided space defined by the base panel 12, the vertical back panel 14, the pair of vertical front panels 16-16 and the top panel 18. Referring to FIG. 4, notice that two fractions of the visible vertical front panel 16 were removed so as to make viewable the elastic band 20.

[0093] When the box-like three-sided pylon 10 is at its deployed configuration said elastic band 20 becomes stretched imposing a predetermined end force “F.sub.B” that maintains said base panel 12 resting against said pair of vertical front panels 16-16 by contacting at a pair of bottom edges 34-34. Simultaneously, an end force “F.sub.T” (equal in magnitude to “F.sub.B” but of opposite direction) maintains said top panel 18 resting against said pair of vertical front panels 16-16 by contacting a pair of top edges 36-36.

[0094] Due to the action of said elastic band 20 the box-like three-sided pylon 10 maintains its deployed configuration. Forces “F.sub.B” and “F.sub.T” prevents unintended folding of the box-like three-sided pylon 10 during utilization.

[0095] Said elastic band 20 could be fashioned as tape- or cord-shaped constructed from rubber-like (or stretchable) material, a spring coil will also be adequate.

[0096] For utilization of said deployed box-like three-sided pylon 10 a seated person might place over his/hers lap the base panel 12, then could place his/hers hands and arms embracing (hugging) a embraceable volume 38 formed by the vertical back panel 14 and the pair of vertical front panels 16-16. Concurrently said seated person may rest his/hers head over the top panel 18 achieving a comfortable posture conducive to relaxation and sleep. To enhance comfort, said seated person may first place over the top panel 18 a pillow 40 (occasionally supplied by medium and long haul airlines carriers) to rest his/hers head above the pillow 40.

[0097] Alternatively, a seated person might place the base panel 12 over an office desk upper surface, over a tray-table available on airplane passenger seats or over a suitable support accessible during seating situations in daily life. Subsequently, the seated person may rest his/hers head over the top panel 18 (or alternatively over a pillow 40 placed above the top panel 18) achieving a comfortable posture conducive to relaxation and sleep.

[0098] FIG. 5 shows, in isometric views, various assembled settings for the box-like three-sided pylon 10, i.e.: folded up mode as required for storage and/or transportation (see top left-hand illustration), unfolding steps necessary to attain a ready for utilization (or completely unfolded) condition, see bottom right-hand illustration.

[0099] It is desirable that when the box-like three-sided pylon 10 is folded up, the five panels comprising the unit (part reference numerals 12, 14, 16-16 and 18) are contacting their contiguous surfaces so that the folded thickness “F” is minimized in order to require minimum storage volume, see on FIG. 5 the top left-hand illustration. Among clamping options available to maintain said five panels contacting, a hook-and-loop fastener system is adequate to attain that objective. A pair of hook sections 42-42 and a pair of loop sections 44-44 are affixed to the vertical front panels 16-16 located opposite and contacting each other when the box-like three-sided pylon 10 is folded up, see on FIG. 5 the top right-hand illustration.

[0100] The following sequential steps are required to unfold a folded up box-like three-sided pylon 10: (1) the hook sections 42s and the loop sections 44s must be detached from each other, (2) then the vertical front panels 16-16 are rotated around the side bendable edges 30s away from each other (see on FIG. 5 the top right-hand illustration), (3) the base panel 12 and the top panel 18 are rotated around the base bendable edge 26 and the top bendable edge 28 respectively stretching the elastic band 20, (4) the vertical front panels 16-16 are rotated into each other until their vertical free rims 32-32 become contacting. At this point the forces “F.sub.B” and “F.sub.T” maintain said base panel 12 and said top surface 18 resting against said pair of vertical front panels 16-16, for clarification read paragraphs [037] and [038], (5) said fastening means 24 is employed to holds together said pair of vertical front panels 16-16.

[0101] Holding together the pair of front panels 16-16 prevents any unintended folding of the box-like three-sided pylon 10 during utilization.

[0102] An assortment of configuration are acceptable to construct said base bendable edge 26, said top bendable edge 28 and said side bendable edges 30-30. Among numerous configuration options, only six of them are depicted by FIG. 6. All illustrated bendable edges are thinner than the thickness “T” of the five adjacent interconnected panels (part reference numerals 12, 14, 16-16 and 18) thus allowing the bendable edges to be bent relatively effortless in order to attain either a folded up or an unfolded assembly.

[0103] The across length “L” for each different bendable edge should vary in order that the five panels comprising the unit (part reference numerals 12, 14, 16-16 and 18) when folded up are contacting their contiguous surfaces so that the folded thickness “F” is minimized. The across length “L” for the base bendable edge 26 and the top bendable edge 28 should be the shortest one (“L” could be approximately equal to “T”.) The across length “L” for a first side bendable edge 30 should be medium size (“L” could be approximately equal to “2T”.) While a second side bendable edge 30 should be the largest one (“L” could be approximately equal to “3T”.) The need for this different across length “L” becomes evident examining the top left-hand illustration on FIG. 5. Their respective location is identified by labels shown on the top illustration from FIG. 13, read paragraph [028].

[0104] The bottom left-hand illustration on FIG. 6 depicts a bendable edge structure when the box-like three-sided pylon 10 is constructed employing the manufacturing process in making “3 Ring binders” (an office stationary commercial product), i.e. two vinyl sheeting 46-46 that are heat-sealed around pieces of rigid panels 48s. Each panel 48 is entrapped (encapsulated) inside individual vinyl pockets such as to form said panels 12, 14, 16-16 and 18 as well as to be cited panels 86 and 88.

[0105] Additional configurations to construct said base bendable edge 26, the top bendable edge 28 and the side bendable edges 30-30 will become apparent to those skilled in the art without departing from the spirit and scope of this disclosure.

[0106] FIG. 7 shows, in front view and cross-section, four configurations suitable to construct said fastening means 24 employed to holds together said pair of vertical front panels 16-16. The top left-hand illustration utilizes a hook button 50 affixed to each of said inner panels 16s and a string tie 52 affixed to one of said hook buttons 50, which allow to fasten together said pair of inner panels 16-16 when said string tie 52 is wound around and under said hook buttons 50-50.

[0107] The top right-hand illustration on FIG. 7 utilizes a hook-and-loop fastener system. A flexible tape 54 is affixed to one of said vertical front panel 16 and the free end of the flexible tape 54 holds a hook segment 56 (part of said hook-and-loop fastener system) and a loop segment 58 (also part of said hook-and-loop fastener system) is affixed to the second inner panel 16. They allow fastening together said pair of vertical front panels 16-16 when the hook segment 56 and the loop segment 58 are affixed together.

[0108] Said top right-hand illustration on FIG. 7 shows a second loop segment 59 placed at a distance “D” from said loop segment 58. When any embody disclosed herein incorporates this particular fastening means 24 option, it provides a second function, namely, when the embodiment is folded up the loop segment 56 and said second loop segment 59 are affixed together so that the folded thickness “F” is minimized in order to attain minimum storage volume, see on FIG. 9 the top left-hand illustration and read on previous paragraphs [043] its first phrase.

[0109] The bottom right-hand illustration on FIG. 7 utilizes a pair of tongues 60-60 formed (into each of said pair of vertical front pane116-16) by a U-shaped cut-out 62 and a string tie 52 affixed to one of said tongues 60s. They allow fastening together said pair of inner panels 16-16 when said string tie 52 is wound around and under said pair of tongues 60-60.

[0110] The bottom left-hand illustration on FIG. 7 utilizes an elastic H-shape clamp 64. Clamp 64 is inserted-and-elongated through a pair of horizontal slots 66s (a cutout existing on each vertical front panel 16). Then said elastic H-shape clamp 64 is rotated about 90 degrees so that a pair of end stubs 68s became relatively vertical preventing disengagement of the elastic H-shape clamp 64 from the pair of vertical front pane116-16. Additional configurations to construct the fastening means 24 will become apparent to those skilled in the art without departing from the spirit and scope of this disclosure.

[0111] The height “H” of the vertical back panel 14 is predetermined to adjust to said seated person's torso size. The width “W” of the base panel 12 and the vertical back panel 14 is predetermined to extend across said seated person's lap. The top panel 18 forward span “S” is predetermined to allow for comfortable head support. The base panel 12 may have a forward span approximately equal to “S”. The expanse “E” pertaining to the vertical front panel 16 (see FIGS. 4 and 5) is predetermined so as to attain a comfortable embraceable volume 38.

[0112] Referring to FIG. 3 notice that an airline passenger is capable of comfortably utilizing the box-like three-sided pylon 10 in order to reach relaxation and sleep while seated inside such a confined space. This advantage is not offered by prior art sleep assist devices. The hereinafter described embodiments offer analogous advantages to a seated passenger. Alternatively, said seated person might place the base panel 12 over the tray-table (not shown on FIG. 3) available between airplane passenger seats

[0113] The unfolded box-like three-sided pylon 10 is folded up by reversing the steps depicted on FIG. 5. The size of a folded box-like three-sided pylon 10 is approximately comparable to a periodical magazine, therefore it can be stored into an airplane's front seat pocket 70 or to be carried in a bag, purse, suitcase or briefcase.

[0114] A variety of adequate materials are readily available to construct the box-like three-sided pylon 10 as well as the following embodiments to be described hereinafter, i.e.: solid or hollow panels or sheets fashioned with ridges to attain rigidity. The material could be recyclable (such as corrugated cardboard) or durable such as corrugated plastic board, vinyl sheeting encapsulating rigid panels, metal, composite types, wood, etc. The stiffness of any part must be sufficient to safely support the loads imposed by a person's head resting atop said top panel 18 and by the action of embracing (hugging) the embraceable volume 38. That stiffness depends on the construction material selected and the magnitude of the thickness “T” of said panels 12, 14, 16-16 and 18 as well as to be cited panels 86 and 88. A particular embodiment can be constructed employing dissimilar construction materials selected from either the list mentioned above or alternative material.

[0115] FIG. 8 shows in side, cross-section and perspective views, a second embodiment for the disclosed “A Sleep Assist Device For Seated Persons”. The second embodiment is depicted at its deployed configuration, namely a ready for utilization mode. The embodiment's folded configuration, suitable for stowing or transport, will be described hereinafter when referring to FIGS. 9. Said second embodiment comprises a box-like three-sided column 72 that includes a base panel 12, a vertical back panel 14, a pair of vertical front panels 16-16, a top panel 18, an elastic band 20, a pair of hookup ends 22-22 and a pair of stopper ridges 74-74.

[0116] The base panel 12 connects to the vertical back panel 14 thru a base bendable edge 26, the top panel 18 connects to the vertical back panel 14 thru a top bendable edge 28 and each vertical front panel 16 connects to the vertical back panel 14 thru a side bendable edge 30.

[0117] Each vertical front panel 16 has an interlocking edge 76 consisting of a multiplicity of tabs78s and a multiplicity notches 80s.When the box-like three-sided column 72 is at its deployed configuration (the ready for utilization mode) said pair of vertical front panels 16-16 contact each other along their interlocking edges 76s inserting tabs 78s and notches 80s into each other. The tabs 78s from a panel 16 that fit into the notches 80s from the adjacent panel 16 prevent vertical shifting between panels 16-16, see bottom illustration on FIG. 8. During utilization, to avoid separation of said pair of interlocking edges 76s, said pair of stopper ridge 74-74 hold together said pair of vertical front panels 16-16. However, if the tabs 78s fit tightly into the notches 80s said pair of stopper ridge 74-74 are not required.

[0118] Holding together the pair of vertical front panels 16-16 prevents any unintended folding of the box-like three-sided column 72 during utilization.

[0119] The ends of said elastic band 20 are simultaneously connected to the base panel 12 and the top panel 18 via a pair of hookup ends 22-22. The elastic band 20 is not viewable at full length because it is enclosed inside the hollow three-sided space defined by the base panel 12, the vertical back panel 14, the pair of vertical front panels 16-16 and the top panel 18. Notice on FIG. 8 that two fractions of a visible vertical front panel 16 were removed so as to make viewable the elastic band 20.

[0120] When the box-like three-sided column 72 is at its deployed configuration said elastic band 20 becomes stretched imposing a predetermined end force “F.sub.B” that maintains said base panel 12 resting against said pair of vertical front panels 16-16 by contacting at a pair of bottom edges 34-34. Simultaneously, an end force “F.sub.T” (equal in magnitude to “F.sub.B” but of opposite direction) maintains said top panel 18 resting against said pair of vertical front panels 16-16 by contacting a pair of top edges 36-36.

[0121] Due to the action of said elastic band 20 the box-like three-sided column 72 maintains its deployed configuration. Forces “F.sub.B” and “F.sub.T” prevents unintended folding of the box-like three-sided column 72 during utilization.

[0122] Said elastic band 20 could be fashioned as tape- or cord-shaped constructed from rubber-like (or stretchable) material, a spring coil will also be adequate, etc.

[0123] For utilization of said deployed box-like three-sided column 72 a seated person might place over his/hers lap the base panel 12, then could place his/hers hands and arms embracing (hugging) a embraceable volume 38 formed by the vertical back panel 14 and the pair of vertical front panels 16-16. Concurrently said seated person may rest his/hers head over the top panel 18 achieving a comfortable posture conducive to relaxation and sleep. To enhance comfort, said seated person may first place over the top panel 18 a pillow 40 (occasionally supplied by medium and long haul airline carriers) and then rest his/hers head above the pillow 40.

[0124] Alternatively, a seated person might place the base panel 12 over an office desk upper surface, over a tray-table available on airplane passenger seats or over a suitable support available during seating situations in daily life. Subsequently, the seated person may rest his/hers head over the top panel 18 achieving a comfortable posture conducive to relaxation and sleep.

[0125] FIG. 9 shows, in isometric views, various arrangement modes for the box-like three-sided column 72, i.e.: folded up mode as required for storage and/or transportation (see top left-hand illustration), and the unfolding steps necessary to attain a ready for utilization (or completely unfolded) condition, see bottom right-hand illustration.

[0126] It is desirable that when the box-like three-sided column 72 is folded up, the five panels comprising the unit (part reference numerals 12, 14, 16-16 and 18) are contacting their contiguous surfaces so that the folded thickness “F” is minimized in order to require minimum storage volume, see on FIG. 9 the top left-hand illustration. In order to maintain said five panels contacting each other there are few optional holding approaches. A hook-and-loop fastener system is adequate to attain that objective (read previous paragraph [052]) when the loop segment 56 and the second loop segment 59 are affixed together.

[0127] Alternatively an expandable band 82 wrapping around the folded up unit is sufficient to maintain said five panels contacting each other. Said expandable band 82 is shown on the top left-hand illustration of FIG. 9 by dashed lines (adjacent to parts 54).

[0128] The following steps are required to unfold the folded up box-like three-sided column 72: (1) either the loop segment 58 and the second loop segment 59 must be detached from each other or alternatively the expandable band 82 must be removed, (2) then the vertical front panels 16-16 are rotated around the side bendable edges 30s away from each other (see on FIG. 9 the top right-hand illustration), (3) the base panel 12 and the top panel 18 are rotated around the base bendable edge 26 and the top bendable edge 28 respectively stretching the elastic band 20, (4) the vertical front panels 16-16 are rotated into each other (bypassing over said stopper ridges 74s) until their interlocking edge 76 become inserting into each other. At this point the forces “F.sub.B” and “F.sub.T” maintain said base panel 12 and said top surface 18 resting against said pair of vertical front panels 16-16, read paragraphs [037] and [038]. The stopper ridges 74s prevent rotation of said pair of vertical front panels 16-16 therefore holds them together. The unfolded box-like three-sided column 72 is ready for utilization.

[0129] When the box-like three-sided column 72 is unfolded, if said expandable band 82 is placed around panels 14 and 16-16 (see bottom right-hand illustration on FIG. 9) it will hold together the pair of front panels 16-16 preventing any unintended folding of the box-like three-sided column 72 during utilization. If either said expandable band 82 or said parts 54, 56, 58 and 59 are included the stopper ridges 74-74 can safely be removed.

[0130] Assortment of configurations are acceptable to construct said base bendable edge 26, the top bendable edge 28 and the side bendable edges 30-30. Among numerous configuration options, six of them are depicted by FIG. 6. All illustrated bendable edges are thinner than the thickness “T” of the five adjacent interconnected panels (part reference numerals 12, 14, 16-16 and 18) thus allowing the bendable edges to be bent relatively effortless in order to attain either a folded up or an unfolded assembly.

[0131] The across length “L” for each different bendable edge should vary in order that the five panels comprising the unit (part reference numerals 12, 14, 16-16 and 18) when folded up are contacting each other all over their contiguous respective surfaces so that the folded thickness “F” is minimized. The across length “L” for the base bendable edge 26 and the top bendable edge 28 should be the shortest one (“L” could be approximately equal to “T”.) The across length “L” for a first side bendable edge 30 should be medium size (“L” could be approximately equal to “2T”.) While a second side bendable edge 30 should be the largest one (“L” could be approximately equal to “3T”.) The need for this different across length “L” becomes evident examining the top left-hand illustration on FIG. 9. Their respective location is identified by labels shown on the top illustration from FIG. 13.

[0132] Additional configurations to construct said base bendable edge 26, the top bendable edge 28 and the side bendable edges 30-30 will become apparent to those skilled in the art without departing from the spirit and scope of this disclosure.

[0133] The height “H” of the vertical back panel 14 is predetermined to adjust to said seated person's torso size. The width “W” of the base panel 12 and the vertical back panel 14 is predetermined to extend across said seated person's lap. The top panel 18 forward span “S” is predetermined to allow for comfortable head support. The base panel 12 may have a forward span approximately equal to “S”. The expanse “E” pertaining to the vertical front panel 16 (see FIGS. 8 and 9) is predetermined so as to attain a comfortable embraceable volume 38.

[0134] Referring to FIG. 3 notice that the seated passenger may also utilizing the box-like three-sided column 72 instead of the box-like three-sided pylon 10 while attaining the same advantage. This advantage is not offered by prior art sleep assist devices.

[0135] The unfolded box-like three-sided column 72 is folded up by reversing the steps depicted on FIG. 9. The size of a folded box-like three-sided column 72 is approximately comparable to a periodical magazine, therefore it allows to conveniently be stored into an airplane's front seat pocket 70 or to be carried in a bag, purse, suitcase or briefcase.

[0136] A variety of adequate materials are readily available to construct the box-like three-sided column 72 as well as the following embodiments to be described hereinafter, i.e.: solid or hollow panels or sheets fashioned with ridges to attain rigidity. The material could be recyclable (such as corrugated cardboard) or durable such as corrugated plastic board, vinyl sheeting encapsulating rigid panels, metal, composite types, wood, etc. The stiffness of any part must be sufficient to safely support the loads imposed by a person's head resting atop said top panel 18 and by the action of embracing (hugging) the embraceable volume 38. That stiffness depends on the construction material selected and the magnitude of the thickness “T” of the panels 12, 14, 16-16 and 18. A particular embodiment can be constructed employing dissimilar construction materials selected from the list mentioned above or alternative material.

[0137] A third embodiment is shown by FIG. 10. Said embodiment is depicted at its deployed configuration, namely a ready for utilization mode. The embodiment's folded configuration, suitable for stowing or transport, will be described hereinafter when referring to FIGS. 11. Said third embodiment comprises a box-like three-sided slanted column 84 that includes a base panel 12, a vertical back panel 14, a pair of slanted vertical front panels 86-86, a slanted top panel 88, an elastic band 20, a pair of hookup ends 22-22 and a fastening means 24.

[0138] The base panel 12 connects to the vertical back panel 14 thru a base bendable edge 26, the slanted top panel 88 connects to the vertical back panel 14 thru a top bendable edge 28 and each slanted vertical front panel 86 connects to the vertical back panel 14 thru a side bendable edge 30.

[0139] Each slanted vertical front panel 86 has a vertical free rim 32. When the box-like three-sided slanted column 84 is at its deployed configuration (the ready for utilization mode) said pair of slanted vertical front panel 86 contact each other along their vertical free rims 32-32. During utilization, to prevent separation of said pair of vertical free rims 32-32, said fastening means 24 are employed to holds together said pair of slanted vertical front panels 86-86.

[0140] Holding together the pair of slanted vertical front panels 86-86 prevents any unintended folding of the box-like three-sided slanted column 84 during utilization.

[0141] The ends of said elastic band 20 are simultaneously connected to the base panel 12 and the slanted top panel 88 via a pair of hookup ends 22-22. Notice that the elastic band 20 is not viewable at full length on the figures because it is enclosed inside the hollow three-sided space defined by the base panel 12, the vertical back panel 14, the pair of slanted vertical front panels 86-86 and the slanted top panel 88. Referring to FIG. 10, notice that two fractions of a visible slanted vertical front panel 86 were removed so as to make viewable the elastic band 20.

[0142] When the box-like three-sided slanted column 84 is at its deployed configuration said elastic band 20 becomes stretched imposing a predetermined end force “F.sub.B” that maintains said base panel 12 resting against said pair of slanted vertical front panels 86-86 by contacting at a pair of bottom edges 34-34. Simultaneously, an end force “F.sub.T” (equal in magnitude to “F.sub.B” but of opposite direction) maintains said slanted top panel 88 resting against said pair of slanted vertical front panels 86-86 by contacting a pair of slanted top edges 90-90.

[0143] Due to the action of said elastic band 20 the box-like three-sided slanted column 84 maintains its deployed configuration. Forces “F.sub.B” and “F.sub.T” prevents unintended folding of the box-like three-sided slanted column 84 during utilization.

[0144] Said elastic band 20 could be fashioned as tape- or cord-shaped constructed from rubber-like (or stretchable) material, a spring coil will also be adequate, etc.

[0145] To utilize said box-like three-sided slanted column 84 a seated person might place over his/hers lap the base panel 12, then could place his/hers hands and arms embracing (hugging) an embraceable slanted volume 92 formed by the vertical back panel 14 and the pair of slanted vertical front panels 86-86. Concurrently said seated person may rest his/hers head over the slanted top panel 88 achieving a comfortable posture conducive to relaxation and sleep. To enhance comfort, said seated person may first place over the slanted top panel 88 a pillow 40 (occasionally supplied by medium and long haul airline carriers) to then rest his/hers head above the pillow 40.

[0146] Alternatively, a seated person might place the base panel 12 over an office desk upper surface, over a tray-table available on airplane passenger seats or over a suitable support available during seating situations in daily life. Subsequently, the seated person may rest his/hers head over the top panel 88 achieving a comfortable posture conducive to relaxation and sleep.

[0147] FIG. 11 shows, in isometric views, various arrangement modes for the box-like three-sided slanted column 84, i.e.: folded up mode as required for storage and/or transportation (see top left-hand illustration), unfolding steps necessary to attain a ready for utilization (or completely unfolded) condition, see bottom right-hand illustration.

[0148] It is desirable that when the box-like three-sided slanted column 84 is folded up, the five panels comprising the unit (part reference numerals 12, 14, 86-86 and 88) are contacting their contiguous surfaces so that the folded thickness “F” is minimized in order to require minimum storage volume, see on FIG. 11 the top left-hand illustration. Among few holding options, a hook-and-loop fastener system is adequate to attain that objective. A pair of hook sections 42-42 and a pair of loop sections 44-44 (although their respective part reference numerals are not depicted on FIG. 11 they are depicted on FIG. 5) are affixed to the slanted vertical front panels 86-86 located opposite to each other when the box-like three-sided slanted column 84 is folded up. Alternatively an expandable band 82 wrapping around the folded up unit is sufficient to maintain said five panels contacting each other.

[0149] When the box-like three-sided slanted column 84 is unfolded, if said expandable band 82 is placed around panels 14 and 86-86 (see bottom right-hand illustration on FIG. 11) it will hold together the pair of front panels 86-86 preventing any unintended folding of the box-like three-sided slanted column 84 during utilization. If said expandable band 82 is included said fastening means 24-24 can be removed

[0150] The following steps are required to unfold the folded up box-like three-sided slanted column 84: (1) either the hook sections 42s and the loop sections 44s must be detached from each other or the expandable band 82 must be removed, (2) then the slanted vertical front panel 86-86 are rotated around the side bendable edges 30s away from each other (see on FIG. 11 the top right-hand illustration), (3) the base panel 12 and the slanted top panel 88 are rotated around the base bendable edge 26 and the top bendable edge 28 respectively stretching the elastic band 20, (4) the slanted vertical front panels 86-86 are rotated into each other until their vertical free rims 32s become contacting. At this point the forces “F.sub.B” and “F.sub.T” maintain said base panel 12 and said slanted top panel 88 resting against said pair of slanted vertical front panel 86-86, and (5) either said fastening means 24 or said expandable band 82 are employed to holds together said pair of slanted vertical front panel 86-86.

[0151] Holding together the pair of slanted vertical front panel 86-86 prevents any unintended folding of the box-like three-sided slanted column 84 during utilization.

[0152] Assortment of configurations are acceptable to construct said base bendable edge 26, the top bendable edge 28 and the side bendable edges 30-30. Among numerous configuration options, six of them are depicted by FIG. 6. All illustrated bendable edges are thinner than the thickness “T” of the five adjacent interconnected panels (part reference numerals 12, 14, 86-86 and 88) thus allowing the bendable edges to be bent relatively effortless in order to attain either a folded up or an unfolded assembly.

[0153] The across length “L” for each different bendable edge should vary in order that the five panels comprising the unit (part reference numerals 12, 14, 86-86 and 88) when folded up are contacting their contiguous surfaces so that the folded thickness “F” is minimized. The across length “L” for the base bendable edge26 and the top bendable edge 28 should be the shortest one (“L” could be approximately equal to “T”.) The across length “L” for a first side bendable edge 30 should be medium size (“L” could be approximately equal to “2T”.) While a second side bendable edge 30 should be the largest one (“L” could be approximately equal to “3T”.) The need for said different across length “L” becomes evident examining the top left-hand illustration on FIG. 11. Their respective location is identified by labels shown on the top illustration from FIG. 13.

[0154] Additional configurations to construct said base bendable edge 26, the top bendable edge 28 and the side bendable edges 30-30 will become apparent to those skilled in the art without departing from the spirit and scope of this disclosure.

[0155] FIG. 7 shows, in front view and cross-section, four configurations acceptable to construct said fastening means 24 that are employed to holds together said pair of vertical front panels 16-16. The top left-hand illustration utilizes a hook button 46 affixed to each of said vertical front panels 16s (or its equivalent slanted vertical front panels 86s) and a string tie 52 affixed to one of said hook buttons 46, which allow to fasten together said pair of inner panels 16-16 (or its equivalent pair of slanted vertical front panels 86-86) when said string tie 52 is wound around and under said hook buttons 46-46.

[0156] The top right-hand illustration on FIG. 7 utilizes a hook-and-loop fastener system. A flexible tape 54 is affixed to one of said vertical front panel 16 (or its equivalent slanted vertical front panel 86) and the free end of the flexible tape 54 holds a hook segment 56 (part of said hook-and-loop fastener system) and a loop segment 58 (also part of said hook-and-loop fastener system) is affixed to the second vertical front panel 16 (or its equivalent second slanted vertical front panel 86). They allow to fasten together said pair of vertical front panels 16-16 (or its equivalent pair of slanted vertical front panels 86-86) when the hook segment 56 and the loop segment 58 are affixed together.

[0157] The bottom right-hand illustration on FIG. 7 utilizes a pair of tongues 60-60 formed into each of said pair of vertical front panel 16-16 (or its equivalent pair of slanted vertical front panels 86-86) by a U-shaped cut-out 62 and a string tie 52 affixed to one of said tongues 60s. They allow to fasten together said pair of vertical front panelsl6-16 (or its equivalent pair of slanted vertical front panels 86-86) when said string tie 52 is wound around and under said pair of tongues 60-60.

[0158] The bottom left-hand illustration on FIG. 7 utilizes an elastic H-shape clamp 64. Clamp 64 is inserted-and-elongated through a pair of horizontal slots 66s a cutout existing on each vertical front panel 16 (or its equivalent slanted vertical front panels 86s). Then said elastic H-shape clamp 64 is rotated about 90 degrees so that a pair of end stubs 68s became relatively vertical preventing disengagement of the elastic H-shape clamp 64 from the pair of vertical front panel 16-16 (or its equivalent pair of slanted vertical front panels 86-86). Additional configurations to construct said fastening means 24 will become apparent to those skilled in the art without departing from the spirit and scope of this disclosure.

[0159] The height “H” of the vertical back panel 14 is predetermined to adjust to said seated person's torso size. The width “W” of the base panel 12 and the vertical back panel 14 is predetermined to extend across said person's lap. The slanted top panel 88 forward span “S” is predetermined to allow for comfortable head support. The base panel 12 may have a forward span approximately equal to “S”. The expanse “E” pertaining to the slanted vertical front panels 86s (see Section C-C on FIGS. 10) is predetermined so as to attain a comfortable embraceable volume 92. The height “H.sub.L” is predetermined to attain a desirable slant angle “α” (see top left-hand illustration on FIG. 10.)

[0160] Referring to FIG. 3 notice that an airline passenger is also capable of comfortably utilizing the box-like three-sided slanted column 84 (instead of the box-like three-sided pylon 10) while attaining the same advantage. This advantage is not offered by prior art sleep assist devices.

[0161] The unfolded box-like three-sided slanted column 84 is folded up by reversing the steps depicted on FIG. 11. The size of a folded box-like three-sided slanted column 84 is approximately comparable to a periodical magazine, therefore it allows to conveniently be stored into an airplane's front seat pocket 70 or to be carried in a bag, purse, suitcase or briefcase.

[0162] A variety of adequate materials are readily available to construct the box-like three-sided slanted column 84 as well as the following embodiment to be described hereinafter, i.e.: solid or hollow panels or plastic sheets fashioned with ridges to attain rigidity. The material could be recyclable (such as corrugated cardboard) or durable (such as corrugated plastic board), metal, composite types, wood, etc. The stiffness of any part must be sufficient to safely support the loads imposed by a person's head resting atop said top panel 18 and the action of embracing (hugging) the embraceable volume 38. That stiffness depends on the construction material selected and the magnitude of the thickness “T” of the panels 12, 14, 86-86 and 88. A particular embodiment can be constructed employing dissimilar construction materials selected from the list mentioned above or alternative material.

[0163] A fourth embodiment is shown by FIG. 12. Said embodiment is depicted at its deployed configuration, namely a ready for utilization mode. The embodiment's folded configuration, suitable for stowing or transport, was described above when referring to the third embodiment, in other words, FIG. 11 equally apply to the fourth embodiment. Said fourth embodiment comprises a box-like three-sided slanted pylon 94 that includes a base panel 12, a vertical back panel 14, a pair of slanted vertical front panels 86-86, a slanted top panel 88, an elastic band 20, a pair of hookup ends 22-22 and a pair of stopper ridges 74-74.

[0164] The base panel 12 connects to the vertical back panel 14 thru a base bendable edge 26, the slanted top panel 88 connects to the vertical back panel 14 thru a top bendable edge 28 and each slanted vertical front panel 86 connects to the vertical back panel 14 thru a side bendable edge 30.

[0165] Each slanted vertical front panels 86 has an interlocking edge 76 consisting of a multiplicity of tabs 78s and a multiplicity of notches 80s. When the box-like three-sided slanted pylon 94 is at its deployed configuration (the ready for utilization mode) said pair of slanted vertical front panels 86-86 contact each other along their interlocking edges 76s inserting into each other. The tabs 78sfrom a slanted vertical front panels 86 fit into the notches 80s from the adjacent slanted vertical front panels 86 preventing vertical shifting between panels 86-86, see bottom right-hand illustration on FIG. 12. During utilization, to prevent separation of said pair of interlocking edges 76s, said pair of stopper ridge 74-74 hold together said pair of slanted vertical front panels 86-86.

[0166] Holding together the pair of slanted vertical front panels 86-86 prevents any unintended folding of the box-like three-sided slanted pylon 94 during utilization.

[0167] When the box-like three-sided slanted pylon 94 is unfolded, if said expandable band 82 is placed around panels 14 and 86-86 (see equivalent depiction on bottom right-hand illustration on FIG. 11) it will hold together the pair of front panels 86-86 preventing any unintended folding of the box-like three-sided slanted pylon 94 during utilization. If said expandable band 82 is included the stopper ridges 74-74 can be removed. Alternatively, the flexible tape 54 (affixed to the first 86,) the hook segment 56 (a part of 54,) the loop segment 58 (affixed to the second 86,) and the second loop segment 59 (also affixed to the second 86,) may replace said expandable band 82 and the stopper ridges 74-74.

[0168] The ends of said elastic band 20 are simultaneously connected to the base panel 12 and the slanted top panel 88 via a pair of hookup ends 22-22. The elastic band 20 may not be viewable at full length on the figures because it is enclosed inside the hollow three-sided space defined by the base panel 12, the vertical back panel 14, the pair of slanted vertical front panels 86-86 and the slanted top panel 88. Referring to FIG. 12, notice that two fractions of the visible slanted vertical front panel 86 were removed so as to make viewable the elastic band 20.

[0169] When the box-like three-sided slanted pylon 94 is at its deployed configuration said elastic band 20 becomes stretched imposing a predetermined end force “F.sub.B” that maintains said base panel 12 resting against said pair of slanted vertical front panels 86-86 by contacting at a pair of bottom edges 34-34. Simultaneously, an end force “F.sub.T” (equal in magnitude to “F.sub.B” but of opposite direction) maintains said slanted top panel 88 resting against said pair of slanted vertical front panels 86-86 by contacting a pair of slanted top edges 90-90.

[0170] Due to the action of said elastic band 20 the box-like three-sided slanted pylon 94 maintains its deployed configuration. Forces “F.sub.B” and “F.sub.T” prevents unintended folding of the box-like three-sided slanted pylon 94 during utilization.

[0171] Said elastic band 20 could be fashioned as tape- or cord-shaped constructed from rubber-like (elastic) material, a spring coil will also be adequate, etc.

[0172] To utilize said box-like three-sided slanted pylon 94 a seated person might place over his/hers lap the base panel 12, then could place his/hers hands and arms embracing (hugging) an embraceable slanted volume 92 formed by the vertical back panel 14 and the pair of slanted vertical front panels 86-86. Concurrently said seated person may rest his/hers head over the slanted top panel 88 achieving a comfortable posture conducive to relaxation and sleep. To enhance comfort, said seated person may first place over the slanted top panel 88 a pillow 40 (occasionally supplied by medium and long haul airline carriers) to then rest his/hers head above the pillow 40.

[0173] Alternatively, a seated person might place the base panel 12 over an office desk upper surface, over a tray-table available on airplane passenger seats or over a suitable support available during seating situations in daily life. Subsequently, the seated person may rest his/hers head over the top panel 88 achieving a comfortable posture conducive to relaxation and sleep.

[0174] FIG. 11 shows, in isometric views, various mode arrangements for the box-like three-sided slanted column 84, i.e.: folded up mode as required for storage and/or transportation (see top left-hand illustration), unfolding steps necessary to attain a ready for utilization (or completely unfolded) condition, see bottom right-hand illustration. Since identical mode arrangements apply to the box-like three-sided slanted pylon 94 no additional figure is included.

[0175] It is desirable that when the box-like three-sided slanted pylon 94 is folded up, the five panels comprising the unit (part reference numerals 12, 14, 86-86 and 88) are contacting each other so that the folded thickness “F” is minimized in order to require minimum storage volume, see on FIG. 11 the top left-hand illustration. Among few holding options, a hook-and-loop fastener system (see part reference numerals 54, 56 and 59 on FIG. 12) is adequate to attain that objective. A pair of hook sections 42-42 and a pair of loop sections 44-44 could be affixed to the slanted vertical front panel 86-86 located opposite to each other when the box-like three-sided slanted column 94 is folded up. That approach is illustrated on FIG. 5.

[0176] The following steps are required to unfold the folded up box-like three-sided slanted pylon 94: (1) either the hook segment 56 and the second loop segment 59 must be detached from each other or the pair of hook sections 42-42 and the pair of loop sections 44-44 must be detached from each other, (2) then the slanted vertical front panel 86-86 are rotated around the side bendable edges 30s away from each other (see on FIG. 11 the top right-hand illustration), (3) the base panel 12 and the slanted top panel 88 are rotated around the base bendable edge 26 and the top bendable edge 28 respectively stretching the elastic band 20, (4) the slanted vertical front panels 86-86 are rotated into each other until their interlocking edges 76s become inserting into each other. At this point the forces “F.sub.B” and “F.sub.T” maintain said base panel 12 and said slanted top panel 88 resting against said pair of slanted vertical front panel 86-86, (5) said pair of stopper ridges 74-74 is employed to holds together said pair of slanted vertical front panel 86-86. The unit is ready for utilization. However, if the tabs 78s fit tightly into the notches 80s said pair of stopper ridge 74-74 are not required.

[0177] Holding together the pair of slanted vertical front panel 86-86 prevents any unintended folding of the box-like three-sided slanted pylon 94 during utilization.

[0178] Assortment of configurations are acceptable to construct said base bendable edge 26, the top bendable edge 28 and the side bendable edges 30-30. Among numerous construction configuration options, six of them are depicted on FIG. 6. All illustrated bendable edges are thinner than the thickness “T” of the five adjacent interconnected panels (part reference numerals 12, 14, 86-86 and 88) thus allowing the bendable edges to be bent relatively effortless in order to attain either a folded up or an unfolded assembly.

[0179] The across length “L” for each different bendable edge should vary in order that the five panels comprising the unit (part reference numerals 12, 14, 86-86 and 88) when folded up are contacting each other all over their contiguous respective surfaces so that the folded thickness “F” is minimized. The across length “L” for the base bendable edge 26 and the top bendable edge 28 should be the shortest one (“L” could be approximately equal to “T”.) The across length “L” for a first side bendable edge 30 should be medium size (“L” could be approximately equal to “2T”.) While a second side bendable edge 30 should be the largest one (“L” could be approximately equal to “3T”.) The need for said different across length “L” becomes evident examining the top left-hand illustration on FIG. 11. Their respective location is identified by labels shown on the top illustration from FIG. 13.

[0180] Additional configurations to construct said base bendable edge 26, the top bendable edge 28 and the side bendable edges 30-30 will become apparent to those skilled in the art without departing from the spirit and scope of this disclosure.

[0181] FIG. 7 shows, in front view and cross-section, four configurations acceptable to construct said fastening means 24 that are employed to holds together said pair of slanted vertical front panel 86-86. The top left-hand illustration utilizes a hook button 46 affixed to each of said vertical front panelsl6s (or its equivalent slanted vertical front panels 86s) and a string tie 52 affixed to one of said hook buttons 46, which allow to fasten together said pair of inner panels 16-16 when said string tie 52 is wound around and under said hook buttons 46-46.

[0182] The top right-hand illustration on FIG. 7 utilizes a hook-and-loop fastener system. A flexible tape 54 is affixed to one of said vertical front panel 16 (or its equivalent slanted vertical front panels 86s) and the free end of the flexible tape 54 holds a hook segment 56 (part of said hook-and-loop fastener system) and a loop segment 58 (also part of said hook-and-loop fastener system) is affixed to the second vertical front panel 16 (or its equivalent slanted vertical front panels 86s). They allow fastening together said pair of vertical front panels 16-16 (or its equivalent slanted vertical front panels 86-86) when the hook segment 56 and the loop segment 58 are affixed together. FIG. 12 depicts the latter fastening means, i.e., includes part reference numerals 54, 56, 58 and 59.

[0183] The bottom said fastening means -hand illustration on FIG. 7 utilizes a pair of tongues 60-60 formed into each of said pair of vertical front panel 16-16 (or its equivalent slanted vertical front panels 86-86) by a U-shaped cut-out 62 and a string tie 52 affixed to one of said tongues 60s. They allow fastening together said pair of vertical front panels 16-16 (or its equivalent slanted vertical front panels 86-86) when said string tie 52 is wound around and under said pair of tongues 60-60.

[0184] The bottom left-hand illustration on FIG. 7 utilizes an elastic H-shape clamp 64. Clamp 64 is inserted-and-elongated through a pair of horizontal slots 66s a cutout existing on each vertical front panel 16 (or its equivalent slanted vertical front panels 86). Then said elastic H-shape clamp 64 is rotated about 90 degrees so that a pair of end stubs 68s became relatively vertical preventing disengagement of the elastic H-shape clamp 64 from the pair of vertical front panel 16-16 (or its equivalent slanted vertical front panels 86-86). Additional configurations to construct the fastening means 24 will become apparent to those skilled in the art without departing from the spirit and scope of this disclosure.

[0185] The height “H” of the vertical back panel 14 is predetermined to adjust to said seated person's torso size. The width “W” of the base panel 12 and the vertical back panel 14 is predetermined to extend across said person's lap. The top panel 18 forward span “S” is predetermined to allow for comfortable head support. The base panel 12 may have a forward span approximately equal to “S”. The height “HL” is predetermined to attain a desirable slant angle “α” (see top left-hand illustration on FIG. 12.)

[0186] Referring to FIG. 3 notice that an airline passenger is capable of comfortably utilizing the box-like three-sided slanted pylon 94 (instead of the box-like three-sided pylon 10) while attaining the same advantage. This advantage is not offered by prior art sleep assist devices.

[0187] The unfolded box-like three-sided slanted pylon 94 is folded up by reversing the steps depicted on FIG. 11. The size of a folded box-like three-sided slanted pylon 94 is approximately comparable to a periodical magazine, therefore it allows to conveniently be stored into an airplane's front seat pocket 70 or to be carried in a bag, purse, suitcase or briefcase.

[0188] A variety of adequate materials are readily available to construct the box-like three-sided slanted pylon 94, i.e.: solid or hollow panels or plastic sheets fashioned with ridges to attain rigidity. The material could be recyclable (such as corrugated cardboard) or durable (such as corrugated plastic board), vinyl sheeting encapsulating rigid panels, metal, composite types, wood, etc. The stiffness of any part must be sufficient to safely support the loads imposed by a person's head resting atop said slanted top panel 88 and the action of embracing (hugging) the embraceable volume 38. That stiffness depends on the construction material selected and the magnitude of the thickness “T” of the panels 12, 14, 86-86 and 88. This embodiment can be constructed employing dissimilar construction materials selected from the list mentioned above or alternative material.
