DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

(9) In this description, any directional prepositions if employed, such as up, upwardly, down, downwardly, front, back, first, second, top, upper, bottom, lower, left, right and other such terms refer to the device or depictions as such may be oriented are describing such as it appears in the drawings and are used for convenience only. Such terms of direction and location are not intended to be limiting or to imply that the device herein has to be used or positioned in any particular orientation.

(10) Now referring to drawings in FIGS. 1-7, wherein similar components are identified by like reference numerals, there is seen in FIG. 1 one preferred mode of the device 10 showing the belt assembly 12 which includes a belt 16 adapted for an encircled engagement of the waist or mid section of the body 14 of the user. Such may be an encircled engagement of the belt 16 which is an elastic circular band, or a belt 16 which has ends which are positionable to a removable engagement.

(11) The belt assembly 12 is shown with a waist belt, or belt 16, and may include a pair of reinforcing flexible belt members 17 extending across the width of the belt 16 from one edge to the opposite edge of the belt 16. Each one of this pair of belt members 17 are positioned on the belt 16 to be inline, or have an axis align with, connections of the first ends of each of the shoulder straps 20 to the belt 16 and confections of first ends of each of the bands 34 to the belt. Such shoulder strap 20 confections might be two mating connectors of the first ends of each shoulder strap 20 to an upper edge of the belt 16, and mating connectors on the lower end of the belt 16. Such connections of the first ends of the bands 34 may be mating connectors as shown herein may be connectors 36 on the bands 34, to rings 28 such as D-rings, extending from an inline connection to the opposite edge of the belt 16. Each of the pair of belt members 17 are preferred and formed of strong but flexible material such as nylon or polyester webbing similar to that of automotive seat belts for example, and are sewn, riveted, or otherwise firmly and permanent attached to the belt 16.

(12) The belt assembly 12 as depicted may be formed of textile fabric such as canvas or rip stop, or a form fitting material such as textile-backed neoprene such as used for wetsuits, or combinations thereof. The belt 16 ends preferably are positionable to a removable engagement, where they may be engaged using releasable cooperative fasteners positioned at one end of the belt 16 adapted to removably engage mating cooperative fasteners at or adjacent the second end of the belt 16. Currently and as depicted in FIG. 2 for example, hook and loop fabric 18 may be employed, or any mating cooperative fastener adapted to hold one end of the belt 16 to the opposite end thereby encircling the body 14 of the user in a removable engagement. Such cooperative fasteners might also include snaps, buttons, hooks, buckles, and other fasteners adapted to the task.

(13) Additionally shown in FIGS. 1-4 and 7, each of a pair of shoulder straps 20, are positionable to an engagement with a first edge of the belt 16 at a frontal position with the belt in the as-used positioning on the user 14. Opposite or second ends 23 of the shoulder straps 20 are in an operative engagement to maintain one shoulder strap 20 on one shoulder of the user and the second of the shoulder straps 20 on the opposite shoulder of the user. By operative engagement is meant, that the engagement of the second ends 23 may vary as noted herein so long one each of the shoulder straps 20 is maintained on a respective shoulder of the user with the device 10 in an as-used position.

(14) This operative engagement may be an engagement of the shoulder straps 20 at second ends 23 extending around to the front of the user, or an engagement with the belt 16 on the back side of the user 14, or an engagement with a secondary belt 16a around the chest of the user 14.

(15) Where a single strap encircles the neck to form two shoulder straps 20, the two second ends 23 of one shoulder strap 20 encircling the neck of the user may be removably engaged or formed as a unitary structure.

(16) Alternatively, two shoulder straps 20 might be employed where first ends of the shoulder straps 20 are in engagements or removably engage with the a first edge of the belt 16 at the front of the user, and second ends 23 of both shoulder straps 20 removably engage at the first edge of the belt 16 on the back of the body 20 of the user in the same fashion as shown in FIG. 1, but on the rear of the waist belt 16, with the belt 16 in the as-used position, or they may be engaged with each other, or to a secondary strap.

(17) The shoulder straps 20 are each in an engagement at one end to the belt 16. This engagement of the ends of the shoulder strap 20 or straps 20 in all modes of the device 10 to front or front and rear of the belt 16, could be permanent such as with rivets or sewing, but preferably for ease of use, is accomplished by the employment of mating fasteners as shown, which easily engage, and must be actuated to disconnect.

(18) As shown in FIGS. 1 and 4 for example, these mating fasteners are provided by quick release buckles 22 which form a strong removable engagement of a buckle insert 24 into a buckle receiver 26 at a first edge of the belt 16 opposite a second edge. Such buckles 22 are easily removably engaged by insertion of the buckle insert 24 into the buckle receiver 26, but will not separate absent the user compressing the distal ends of members of the buckle insert 24 to disengage the buckle receiver 26. Of course other mating fasteners may be employed as would occur to those skilled in the art, such as snaps, hooks, rings, of other mating fasteners which easily engage and must be actuated to release.

(19) Also depicted in FIG. 1 and other figures herein, are a first leg belt 30 configured to encircle one leg of the body 14 of the user about the thigh, and a second leg belt 32 adapted to encircle the second leg of the body 14 of the user. The leg belts 30 and 32 are preferably constructed of elastic material which may be stretched during engagement around their respective positions on the thigh or upper legs of the user, and which will engage the legs in an inwardly biased compressive engagement. This compressive engagement helps maintain each of the leg belts 30 and 32 in a fixed position on each respective leg of the user around the thigh. Currently a textile backed or laminated neoprene fabric similar to that employed in wetsuits, is a preferred material due to its elastic qualities yet comfortable engagement when encircling the leg.

(20) The leg belts 30 and 32, may have easily removably engageable mating fasteners positioned at or adjacent each of the two ends of the leg belts 30 and 32, such as hook and loop fabric 18 (FIG. 2) which may be a combination hook and loop fabric, or a section of hook type fabric fastener and a section of loop type fabric fastener. As noted, such mating fasteners can also include snaps, buttons, hooks, or other means of engaging both ends of a leg belt or lower leg belt removably, to each other as would occur to those skilled in the art.

(21) Alternatively, but not as easily engaged to the legs, the leg belts 30 and 32, may be formed as a connected ring structure with no loose ends, which may be slid upon the upper leg over the foot, and up to a compressively engaged position on the legs of the user. In either mode, a leg belt 30 and 32 encircles each leg of the user, and is adapted to form a compressive engagement with the exterior surface of the upper leg to help hold it stationary during use.

(22) Shown in FIG. 2, is a rear view of the device 10 herein during engagement with the body 14 of a user. The strap 20 configuration shown in FIG. 2, is employed with the mode of the device 10 shown in FIGS. 3-4. As can be seen in FIG. 2, each of two shoulder straps 20 are formed of a flexible material in a permanently curved shape, where one each of the shoulder straps 20 will extend first in a linear shape such as shown in FIGS. 1 and 4, and which will then curve in shape as it passes over the shoulder of the user as in FIGS. 2 and 3.

(23) The fabric forming the permanently curved shoulder straps 20 as shown in the particularly preferred mode of the device 10 of FIGS. 2-5, may be a combination of flexible webbing or other material for the linear section engaging the belt 16 at the front of the user, and a flexible material, which once cut, which will hold a curved shape as in FIGS. 2-3 for a second section 21 of the two straps 20. Currently a neoprene textile material having neoprene laminated to a cloth backing, similar to that used for wetsuits works well for the second section 21 as it may be cut in a curved shape for the second section 21, and will hold that shape.

(24) This permanently curved shape of the shoulder straps 20, without a connection to the belt 16 on the back of the user 14, is preferred for two reasons. First by not connecting the second ends of the shoulder traps 20 to the belt 16 on the back of the user 14, experimentation as shown the device 10 is easier to use when running or walking, and also encourages the user to use back and torso muscles for posture during running and walking and thus exercising them. Also, as it has been found forming the shoulder straps 20 permanently curved, makes the shoulder straps 20 more comfortable when worn, and especially easy to connect as shown in FIG. 4, across the chest of the user. The second ends of each of the shoulder straps 20 opposite the first ends having the connection to the belt 16 may be engaged to each other in this fashion using the shown hook and loop fastener material 18 operatively positioned at each of the ends.

(25) Also shown in FIGS. 2-3 are an engagement for both ends of the belt 16, to secure it around the waist of the user. A first end of the belt 16 is engaged to a second end of the belt 16 as depicted in FIGS. 2-3. As shown, a belt fastener to engage both ends is provided by a passage at one end of the belt 16 such as a ring 28 or formed passage in the belt 16, allows for a first end of the belt 16 to be threaded therethrough, and engaged with a fastener such as hook and loop fabric 18 positioned in between the first end of the belt 16 and the opposite end. The user may thus pull the first end of the belt 16 through the ring 28, and using hook and loop fabric 18 thereon, engage it to another section of hook and loop fabric 18 on the belt 16.

(26) This belt 16 engagement may be seen in FIG. 3, which also shows the overlap of the ends of the first leg belt 30 and second leg belt 32 which are held in the encircled engagement by the connected removable fasteners thereon such as the hook and loop fabric 18 shown in FIG. 2. Of course other connections to secure the first end of the belt 16 to the second and around the waist of the user may be employed.

(27) As shown in FIG. 4 which is a frontal view of the device 10 of FIGS. 2 and 3, and also shown in FIG. 1, elastic bands 34 are connected between the second edge of the belt 16 and a connection with the leg belts 30 and 32. The elastic band 34 may be formed of rubber, or fabric-covered rubber or other elastic material which will elongate and concurrently impart resistance to such elongation. The force of the resistance may be varied by making the elastic bands 34 thicker, or of rubber and rubber like materials having varying resistance to elongation. Such may be provided in a kit such as in FIG. 6.

(28) At each end of each elastic band 34 is positioned a releasable connection to the belt 16 and a releasable connection to a leg belts 30 or 32. Such may use a releasable connector 36, which is adapted to engage the ring 28 positioned on the belt 16 and on an opposite end, with a ring 28 positioned upon a leg belts 30 or 32. Other releasable connections between the belt 16 and the bands 34 may be employed however the ring 28 and connector 36 work well and are simple to use.

(29) The releasable connector 36 might be a hook with an open end, however, a ring 28 which has a biasly-closed opening such as a spring loaded opening found on a carabineer, has been found to yield a very secure engagement. While secure during use, such a carabineer type connector 36 is also easily disengaged by opening the spring loaded door of the carabineer to slip if from the ring 28 to which it engages.

(30) As noted above, FIG. 4 shows a particularly preferred mode of the device 10, in an as-used positioning of the belt 16, with the shoulder straps 20 connected to the belt 16 which is encircling the waist or mid section of the user. The shoulder straps 20 are formed in the noted permanently curved configuration, with each respective permanently curved portion (FIGS. 2-3) following a curved pathway around the neck and back of the user 14 and under an arm opposite the side of the belt 16 to which they engage to each other at respective second ends 23. This places the removable engagement of the second ends 23 of the straps 20, in view of the sight of the user during positioning of the device 10 to the as-used positioning allowing for easy engagement and disengagement of the second ends 23 while viewing them.

(31) Also shown, are the two elastic members or elastic bands 34 extending between connections at a first and second leg belt 30 or 32, and the waist-engaged belt 16. So configured and in the as-used position, the device 10 communicates resistive force from the elongating elastic bands 34 to the legs of the user as noted above, thereby increasing the strength of the leg muscles from exercise during walking and running.

(32) In a particularly preferred mode of the device 10, the axis of both shoulder straps 20, shown running along imaginary line V1 of one shoulder strap 20 in FIG. 7, are substantially aligned with the axis of the elastic bands 34 also shown running along imaginary line V1, extending between the belt 16 and the leg belts 30 and 32 substantially align along a vector V1 (FIG. 7). By substantially aligned is meant that the axis shown as V1 in of both the straps 20 and the bands 34 are aligned at the junction thereof provided by the connectors 36, that both are aligned in a straight line, or at a dogleg at the junction point of the connectors 36 that the bands 34, where the axis of the straps 20 extends along a line that is within 4-12 degrees of the axis of the bands 34, with a favored configuration of alignment or within 5 degrees of being aligned. Further, if employed, the vector V2 (FIG. 7) formed along the axis of each of the elongated elastic leg bands 35 intersect at one end, with the rings 28 engaged to the leg belts 30 and 32 and would align with the axis of the bands 34 shown as running along V1, or would be within the same degree range noted above.

(33) Thus, in substantial alignment of the axis of the straps 20 with the axis of the bands 34, shown as running along V1 can align with that of the straps 20 and elastic bands 34 when stretched, or form a dogleg therebetween at the junction formed by the connectors 36 and rings 28 on the waist belt 16 which deviates between 4-12 degrees or preferably at 5 degrees or less from being a straight line shown as V1. Further, in such a substantial alignment where the leg bands 35 are included the vector V2 determined by the axis of the leg bands 35 stretching between the shoes 48 and the lower leg belts 42 and 44, intersects the distal end connection of the ring 28 on the leg belts 30 and 32.

(34) The substantially aligned shoulder straps 20, belt members 17, and elastic bands 34, which is preferred, serve to maintain the resistive force constant from the elongated elastic bands 34 or elongated elastic leg bands 35 if used, and also aligned during use. This alignment has been found to significantly enhance the results from the device 10 and ease of its use by the user by maintaining a constant aligned resistive biasing forces in position on their body 14. Further, when included with lower leg belts 42 and 44 (FIG. 7) and leg bands 35, it is preferred the belt 16, leg belts 30 and 32, and leg bands 35 are all configured by positioning the releasable connections to the bands 34 or leg bands 35 as the case may be, such that the leg bands 35, bands 34 and shoulder straps 20, are all substantially aligned, with the device engaged to the user. Such is depicted in FIG. 7 for example.

(35) As also noted, FIG. 4a, depicts complimentary mating connectors shown as buckles 22 with first buckle insert 24 engageable with the buckle receiver 26.

(36) FIG. 5 depicts another mode of the device 10 showing a shoulder harness configured as a single piece which would be slid over the head of the user. It includes the curved straps 20 which are engaged at one end to an encircling belt which can be removably connected across the chest of the user.

(37) In FIG. 6 is depicted elastic members shown as elastic bands 34 which are engaged at both ends with connectors 36 shown as carabineers. As shown, the plurality of provided elastic bands 34 form a kit 38 of such elastic members where each may have a different force of resistance to elongation, thereby allowing the user to choose elastic bands 34 from the kit which are appropriate for the amount of force they wish to overcome during an exercise period. The leg bands 35 may also be provided as a kit 38 in the same manner as depicted in FIG. 6 to vary resistance.

(38) In FIG. 7 is shown a mode of the device 10 herein having two more resistance leg bands 35 extending between a releasable connection such as with connectors 36 and rings 28, formed at a first end of each of a respective one of the elastic leg bands 35. The leg bands 35 also have a second respective releasable connection, with a first lower leg belt 42 and with a second lower leg belt 44. As with the other bands 34 other releasable connections may be employed such as hooks, snaps, tying, or other means to releasably engage the leg bands 35 at both ends.

(39) Both the first lower leg band 42 and the second lower leg band 44, are formed of fabric which either slides over the leg to a biased compressed engagement with the leg just above the knee, or of fabric which encircles the lower leg just above the knee and engages with mating fasteners 46 such as hook and loop fabric, snaps, hooks, or other matting fasteners which will hold a first end of the leg belts 42 and 44 to a second end.

(40) The leg bands 35, as with other bands 34 herein, are elastic and produce a resisting biasing force to stretching. They may be chosen by a resistance level to increase or decrease the workout, but in all modes the leg bands 35, once connected between connectors 36 engaged with the leg belts 42 and 44, and the shoes 48 of the user, are short enough to establish a biased and tight engagement with no slack.

(41) Preferably, the second ends of both leg bands 35 are adapted in a releasable connection at second ends, which removably engages with the shoelaces 50 of the shoes 48 of the user. This makes for an easy engagement and it has been found that the resistance from the elongated elastic leg bands 35 imparting a pulling force upon the top of the foot engaged in the shoe 48, works best, for exercising the lower legs and feet during walking and running. While another strap (not shown) may be engaged around the middle of the shoe 48 and provide a ring 28 to removably engage the connector 36 on the leg bands 35, such a band would have to wrap around the shoe 48 and under the sole on which the user walks, and has been found in experimentation in some users, to impede their walking and be a source of tripping.

(42) Consequently, adapting the leg bands 35 on second ends with a releasable connection adapted to engage with the shoelaces on the tops of the shoe 48 is particularly preferred for both convenience, and to eliminate any extra thickness on the bottom of the sole of the shoe 48 which would impede normal walking or running for users. Such an adapted engagement can be accomplished with connectors 36, or hooks, or small straps with buckles or hook and loop fabric, or the like which will engage around one or more of the shoelaces 50, and hold the second end of the leg bands 35 adjacent the shoe 48, where the biasing force of the elastic in the leg bands 35 will pull upward from the laces 50.

(43) While all of the fundamental characteristics and features of the exercise device system herein have been shown and described herein, with reference to particular embodiments thereof, a latitude of modification, various changes and substitutions are intended in the foregoing disclosure and it will be apparent that in some instances, some features of the invention may be employed without a corresponding use of other features without departing from the scope of the invention as set forth. It should also be understood that upon reading this disclosure and becoming aware of the disclosed novel and useful device and system herein disclosed, that various substitutions, modifications, and variations may occur to and be made by those skilled in the art, without departing from the spirit or scope of the invention. Consequently, all such modifications and variations and substitutions, as would occur to those skilled in the art are considered included within the scope of the invention as defined by the following claims.
