DESCRIPTION OF A PRESENTLY PREFERRED EMBODIMENT

(16) A presently preferred embodiment of an overbed table in accordance with the presently disclosed invention is shown and described in connection with FIGS. 1-13. With particular reference to FIGS. 1-3, an overbed table 20 includes a support platform 22 and an elongate member 24. Elongate member 24 includes a first end 26 that is connected to support platform 22 and a second end 28 that located oppositely on elongate member 24 from first end 26. Embodiments such as shown in FIGS. 1-3 with a single elongate member 24 are generally preferred by patients in hospital beds because the support platform 22 will fit under the patient's bed. In some embodiments, more than one elongate member 24 can be used in cooperation with support platform 22. In such cases, two or more elongate members 24 may provide appropriate support for patents in wheelchairs or recliners. For example, FIG. 4A shows an embodiment wherein two elongate members 24 are used to support the table from the support platform 22.

(17) Overbed table further includes a desktop body 30 that is connected to the second end 28 of elongate member 24. As also shown in FIG. 4A, in some cases more than one elongate member can be connected to support platform 22 and to desktop body 30. Desktop body 30 defines a front side 32 and a back side 34. A flexible table top 36 includes a table top frame 38 and a flex top 40. Table top frame 38 defines a front edge 42 and a back edge 44. Table top frame 38 is pivotally connected to desktop body 30 adjacent to back side 34. Table top frame 38 defines two raised edges 46, 48 that are oriented in the direction between front edge 42 and back edge 44 of table top frame 38. Raised edges 46, 48 define respective tracks 50, 52 therein.

(18) Flex top 40 includes first panel 54 and second panel 56. Panel 54 defines top surface 58 and bottom surface 60. Panel 56 defines top surface 62 and bottom surface 64. Panels 54 and 56 are pivotally connected together along a folding axis 66 by an integral hinge 68. Integral hinge 68 defines a continuous even surface 70 between top surface 58 of panel 54 and top surface 62 of panel 56. Integral hinge defines a groove 72 between the bottom surface 60 of panel 54 and bottom surface 64 of panel 56. Flex top 40 includes following members such as pins 74, 76 that extend through tracks 50 and 52 respectively.

(19) At times when pins 74, 76 are at a first stop 78, 80 in tracks 50, 52 respectively, the top surfaces 58, 62 of panels 54, 56 define a planar surface. At times when pins 74, 76 are located at stops 82, 84 that are closer to front edge 42 of table top frame 38 than first stop 78, 80, panels 54 and 56 pivot to form a peak 86 therebetween along axis 66.

(20) Details of support platform 22 are more particularly shown and described in connection with FIG. 4. Support platform 22 may include, for example, feet 88 that are mounted on casters 90 and joined by a base rail 92. Support platform 22 establishes a horizontal plane of support for the overbed table.

(21) FIG. 4 also shows that elongate member 24 extends from support platform 22 in a direction that is normal to the horizontal support plane established by support platform 22. In the embodiment of FIG. 4, elongate member 22 includes telescoping part 94, 96 such that length of elongate member 22 can be modified by moving telescoping parts 94, 96 with respect to each other in the longitudinal direction.

(22) As shown in FIGS. 4-6, in the preferred embodiment of the disclosure, a desktop body 30 includes a frame 98 that is fastened to second end 28 of elongate member 24 and a shell 100 that is fastened to frame 98. Shell 100 may be a molded body of the type that defines compartments 102 therein.

(23) Referring to FIGS. 5-7, the disclosed overbed table further includes a armrests 103 that are secured to desktop body 30 by slide assembly 104. Slide assembly 104 includes a slide housing 106 that is fastened to desktop body 30 and a rail 108 that is slidingly engaged in slide housing 106. Rail 104 is moveable within slide housing 106 and slide housing 106 is oriented on shell 100 of desktop body 30 such that rail 104 is moveable in the direction toward and away from front side 32 of said desktop body 30.

(24) Armrests 103 are secured to respective rails 108 of corresponding slide assemblies 104. Armrests 103 are moveable together with rail 108 so that the position of armrests is easily adjusted by the user.

(25) FIG. 5 shows armrests 103 in an extended position and FIGS. 1-3 shows armrests 103 in a retracted position. From this it can be appreciated that slide assembly 104 is oriented with respect to shell 100 and desktop body 30 such that the movement of armrest 103 in the direction from the back side 34 of desktop body 30 toward front side 32 of desktop body 30 is inclined downwardly with respect to said desktop body. The particular pitch or degree of downward incline is determined according to the orientation of slide housing 104 as secured to shell 100.

(26) In some embodiments, the disclosed overbed table includes a desktop body 30 wherein the shell 100 includes a gasket that is located on shell 100 of desktop body 30. Gasket 110 is positioned between shell 100 of desktop body 30 and armrest 103 to seal against fluid flow between desktop body 30 and the underside of armrest 103. Gasket 110 thus seals against the flow of fluids that may be spilled on or around shell 100 and flow to parts of the overbed table that would be more difficult and expensive to clean.

(27) FIGS. 2, 3, 5 and 6 show that table top frame 38 of flexible table top 36 is pivotally connected to desktop body 30 by hinges 112. Hinges 112 are secured adjacent back edge 44 of table top frame 38 and are also secured adjacent back side 34 of desktop body 30. In this way, the user can access shell 100 and compartments 102 by raising the front of table top frame 38 to expose shell 100. To avoid inadvertent closing of table top frame 38, hinges 112 may be friction hinges.

(28) FIGS. 8, 9 and 13 show table top frame 38 wherein raised edges 46, 48 further define openings 114, 116 that are located in raised edges 46, 48 respectively. Openings 114, 116 are located between respective track 50, 52 of edges 46, 48 and front edge 42 of table top frame 38. Correspondingly, flex top 40 includes fasteners 118, 120 that are extendable through openings 114, 116 of raised edges 46, 48 at times when fasteners 118, 120 are respectively aligned with openings 114, 116. In this way, flex top 40 is connected to table top frame 38, preferably at a location near the front edge 42 of table top frame 38. Fasteners 118, 120 are retractable in the longitudinal direction of the fasteners such that they are moveable out of openings 114, 116 to uncouple the front of flex top 40 from table top frame 38 thereby leaving flex top 40 pivotally connected to table top frame 38 by pins 74, 76 at times when fasteners 118, 120 are out of opening 114, 116.

(29) In the presently preferred embodiment, fasteners 118, 120 are normally biased to extend through openings 114, 116 at times when the fasteners are respectively aligned with the openings. Fasteners 118, 120 may be of the type that they can be manually displaced from openings 114, 116. Is some embodiments, fasteners 118, 120 may be spring plungers.

(30) FIGS. 8, 9 and 13 also show that tracks 50, 52 of table top frame 38 define one or more stops 82, 84 that are located at respective positions along tracks 50, 52 respectively, Stops 82, 84 are configured to allow respective pins 74, 76 to travel along the respective track 50, 52 past stops 82, 84. At the same time, stops 82, 84 also provide a seat for maintaining pins 74, 76 at the position of a selected stop 82, 84 as the user of the overbed table may elect. The user may bypass stops 82, 84 by moving pins 74, 76 over or around the stops. The user may engage pins 74, 76 with stops 82, 84 by positioning the pins against a selected stop.

(31) In the presently preferred embodiment, FIGS. 1-3, 5 and 10-13 show that flex top 40 includes a third panel 122 that is connected to first panel 54 by a second integral hinge 124. Third panel 122 has a side 126 that is located on third panel 122 oppositely from second integral hinge 124. Side 126 defines a concave edge to allow the user closer access to flex top 40. Third panel 122 further defines first and second edges 128, 130 that are oppositely disposed on third panel 122 from each other.

(32) At times when fasteners 118, 120 are in their normally biased state, the fasteners extend from first and second edges 128, 130 respectively. To remove fasteners 118, 120 from openings 114, 116 respectively, the user manually presses inwardly against the ends of fasteners 118, 120 in the longitudinal direction to overcome the bias force of fasteners 118, 120 and push the respective ends of the fasteners out of openings 114, 116. Flex top 40 is then pivotally connected to fable top frame 38 by pins 74, 76 such that flex top 40 be pivoted upwardly from the front edge 42 to afford access to the bottom of flex top 40 so that it can be quickly and easily cleaned.

(33) Also shown in FIGS. 1-3, 5 and 10-13, the preferred embodiment of flex top 40 may include a fourth panel 132 that is connected to second panel 56 by a third integral hinge 134. Fourth panel 132 defines a side 136 that is located oppositely on said fourth panel 132 from third integral hinge 134. Also, fourth panel 132 defines first and second edges 138, 140 that are oppositely disposed on fourth panel 132 from each other. Pins 74, 76 extend from first and second edges 138, 140 respectively.

(34) In the operation of flex top 40, starting with fasteners 118, 120 engaged in openings 114, 116 and pins 74, 76 engaged with the first stops 78, 80 respectively, the flex top 40 has a planar geometry that is essentially parallel to the plane of table top frame 38. To form the folded top feature of the disclosed overbed table as shown in FIGS. 1 and 13, pins 74, 76 are moved from first stops 78, 80 and urged forward through tracks 50, 52 to a selected one of stops 82, 84. This movement causes first panel 54 to cooperate with second panel 56 to form a peak 86 along folding axis 66. The steepness of the peak 86 depends on the stop 82, 84 that the user, in their own discretion, selects. The closer the stop 82, 84 to side 126 of flex top 40, the steeper the peak that is formed.

(35) FIGS. 10-12 show that third panel 122 defines a bottom surface 142 and a top surface 144 that is oppositely disposed on the third panel from the bottom surface. Second integral hinge 124 defines a continuous, even surface between top surface 58 of first panel 54 and top surface 144 of third panel 122. Similarly, fourth panel 132 defines a bottom surface 146 and a top surface 148 that is oppositely disposed on fourth panel 132 from bottom surface 146. Third integral hinge 134 defines a continuous, even surface between top surface 62 of second panel 56 and top surface 148 of fourth panel 132.

(36) As shown in the drawings, second integral hinge 124 defines a groove 150 between bottom surface 60 of first panel 54 and bottom surface 142 of third panel 122. Similarly, third integral hinge 134 defines a groove 152 between bottom surface 64 of second panel 56 and bottom surface 146 of fourth panel 132.

(37) As particularly shown in FIGS. 1-3 and 10-13, at times when flex top 40 is in a folded position, top surface 58 and top surface 144 define an included angle that is less than 180 degrees and top surface 62 and top surface 148 also define an included angle that is less than 180 degrees. At the same time, the angle between top surface 54 and top surface 62 when flex top 40 is in a folded position is greater than 180 degrees. Nevertheless, grooves 72, 150 and 152 are all on the bottom side of flex top 40. In this way, the top surface of flex top 40 that is formed by the top surfaces 58, 62, 144 and 148 in combination with integral hinges 68, 124 and 134 forms a continuous, even, integral surface. The top surface of flex top 40 thus formed is without cracks or separations between panels 54, 56, 122 and 132 that could result in discontinuities between adjacent panels. Such features are potential sources for leakage of fluids spilled on flex top 40 or ridges that interfere with certain user activities such as writing as well as other annoyances and inconveniences. In this way, the integral surface of flex top 40 provides an overbed table that is easier to clean and less prone to penetration of fluids, dust and other contaminants that make cleaning the overbed table difficult and costly.

(38) As also shown in the drawings, first panel 54 defines a first edge 154 and a second edge 156 that is oppositely disposed on first panel 54 from first edge 154. The top surface 58 of panel 54 of flex top 40 defines a first border segment 158 and a second border segment 160. Border segments 158 and 160 are adjacent first and second edges 154, 156 respectively of first panel 54. The top surface of first and second border segments 158, 160 of first panel 54 are elevated from the top surface 58 of the portion of first panel 54 that is between first and second border segments 158, 160. Also, top surface 58 of the portion of first panel 54 that is between first and second border segments 158, 160 is inclined with respect to the top surface of border segments 158, 160. The sense of the incline across the top surface is downwardly in the direction from first integral hinge 68 toward the concave side 126 of flex top 40.

(39) Similarly to the top surface of first panel 54, second panel 56 defines a first edge 162 and a second edge 164 that is oppositely disposed on second panel 56 from first edge 162. The top surface of second panel 56 of flex top 40 defines a first border segment 166 and a second border segment 168. First and second border segments 166, 168 are adjacent first and second edges 162, 164 of second panel 56. The top surface of first and second border segments 166, 168 of second panel 56 are elevated above the top surface 62 of the portion of second panel 56 that is between first and second border segments 166, 168. The top surface of the portion of second panel 56 between first and second border segments 166, 168 is also inclined with respect to the top surface of first and second border segments 166, 168. The sense of the incline across the top surface is downwardly in the direction from side 136 of flex top 40 toward first integral hinge 68.

(40) The structure of first and second border segments 158 and 160 in combination with first and second border segments 166, 168 together with inclined portions of the top surfaces 58 and 62 between those border segments causes fluids that may be spilled on top surfaces 58, 62 of panels 54, 56 to pool on the top surface of flex top 40 near the concave side 126 of third panel 122. Thus, here again the disclosed overbed table provides for quick and easy cleanup of spilled liquids.

(41) To save on material costs to reduce the weight of first panel 54 and second panel 56, the bottom surface 60 of first panel 54 defines a recessed area 170 between first and second edges 154, 156 of the first panel. Similarly, the bottom surface 62 of second panel 56 defines a recessed area 172 between first and second edges 162, 164 of second panel 56. This reduction in weight helps to make operation of the flex top easier.

(42) While certain presently preferred embodiments of the disclosed invention have been shown and described herein, the scope of the invention is not limited thereto, but can be otherwise embodied in the following claims.
