The contact support structure may also comprise two sets of independently acting contact support members that allow the front roller to move independently of the rear roller. Also disclosed is an embodiment wherein the arcuate roller assembly rocks back and forth about the surface of a horizontal cross support member of the base structure.

Description

FIELD OF THE INVENTION

This invention relates generally to the field of multi-direction reclining and stretching chairs.

BACKGROUND OF THE INVENTION

Reclining and stretching chairs are not new per se. Chairs that recline have been manufactured for many years. With the development of anatomical and ergonomic engineering, reclining chairs have evolved to be more comfortable and more versatile.

Various chairs have been designed that provide the capability to stretch and strengthen muscles. For example, U.S. Pat. No. 3,561,772 discloses a lightweight, reclining and exercising device that includes pivoting panels that are connected with a fixed pivot member. The chair is specifically designed to stretch and strengthen the back muscles. U.S. Pat. No. 3,641,995 shows an exercising chair that also includes a fixed pivot axle between a seat and a back section and is used to exercise the back and leg muscles.

There are also numerous chairs manufactured that are primarily designed to recline and be comfortable. Many of the existing recliners include interconnected platform members that are adjustable in different ways. In U.S. Pat. No. 3,934,932 the angle between an interconnected seat and back platform is adjusted with a frictional coupler that is attached to the seat platform and a tubular portion of the base. U.S. Pat. No. 4,790,599 shows a chair having a fixed angle between the chair and the seat platform. The combined chair and seat platform swings about a raised pivot point and is adjusted along a fixed track positioned on the base of the chair.

What is needed is a chair that can be moved by the user through a range of different therapeutic and generally comfortable motions including tilting, rocking and angular changing between platform components on the body platform assembly. The chair should allow the person sitting, reclining or stretching in the chair to be able to change the angular position of the platform components freely by shifting their weight. Ideally, the chair should be easy to lock in any desired position.

SUMMARY OF THE INVENTION

The present invention provides a new and improved chair design that allows interconnected seat and back platform members to move freely relative to the confines of corrals. Each end of an axle member that is rotatably attached to the center portion of the body support platform extends beyond each side of the body support platform and into the corrals in the side walls of the base. The corrals are defined by openings or indentations in the side walls of the base of the chair. The corral openings can be in the shape of a oval, a circle or in the shape of a slot. The corral openings can also be of an amorphous shape having semi-circular regions about the perimeter configured generally to cooperate with the axle. Typically, the corral openings are at least one and one half times the diameter of the axle members in all directions. The chair includes a roller assembly that is positioned between the base and the interconnected body support platform. In the first preferred embodiment, the roller assembly includes contact support members that can pivot and lock relative to the base. One roller is attached to one end of the contact support members and a second roller is attached to the other end of the contact support members. An optional leg platform can be interconnected to the seat platform and an optional head platform can be attached to the back platform. An additional pivoting section can be formed as a part of the back section to create a section localized to the lumbar portion of the back.

The individual platforms can be interconnected with adjustable hinges. The adjustable hinges may be fixed in position or provided with a spring assisted tensioning mechanism.

In a second preferred embodiment the arcuate contact support structure rolls back and forth on the upper surface of a horizontal base member.

In a third preferred embodiment a guide structure is positioned parallel to one or both sides of the contact support structure between the contact support structure and one or both walls of the base structure. Control rods or control segments extend outward from the contact support structure into guide slots positioned on the guide structure. The guide structure provides structural stability to the base structure and to the entire chair assembly.

In a fourth preferred embodiment the base structure includes two spaced apart pivot members that cooperate with two spaced apart notches that are positioned on the lower side of the contact support structure. This embodiment may also include a guide structure to increase the structural stability of the chair assembly.

In a fifth preferred embodiment the contact support structure includes separate front and rear members. Each of the separate members includes a roller member on the top and each member is independently adjustable along a guide slot.

The resulting construction in any of the preferred embodiments provides a wide range of comfortable seating, reclining and stretching positions. Because the body platform is free to move on the axle within the annular corral, the chair provides the user with the capability to stretch their back whether they are sitting, reclining or fully stretching out in a prone position. The chair in the first preferred embodiment can be positioned in a conventional upright orientation. The chair can be entered in the conventional manner and reclined if the person in the chair leans back by pushing back on the armrests and tilting the contact support structure on its pivot. The contact support structure can be fixed at any desired position by securing the control rod within the guide slots that are located on each side of the base structure. As the user leans further back in the chair and approaches a horizontal reclined position, the user's weight becomes nearly equally distributed and balanced between the two rollers, and simultaneously centered over the corral. With or without the roller assembly in a secured position, the user can then arch his or her back which lifts the axle within the corrals. In any position, the user can relax and the chair will stay in position even with the axle "free floating" within the corrals. This unexpected and surprising advantage is caused by the frictional interface between the roller members and the body support platform assembly. The body support platform assembly includes a back, seat, lumbar and optional head and leg platforms. Each of the body platform sections can be interconnected with resilient, locking, spring connections. The body support platform assembly allows the user to flex his or her body into any position while simultaneously providing support for all parts of the body in all positions. The body support platform can be urged into the desired position and it will stay in place until the user moves. The user is free to move, stretch or resituate into any desired position on the chair.

The chair provides several additional surprising and unexpected advantages. For example, when the user is near the reclined (or horizontal) position, the user can lie on his or her side or stomach and the chair will move as required to accommodate the user's movements. The user can also rock back and forth on the contact support pivot and flex up and down within the corral. The two combined motions can create a therapeutic circular rolling effect. The user can also pull down on the arms of the chair to cause the chair to float down into the conventional upright position and then easily get out of the chair.

Refer now to FIGS. 1 and 2, which show the first preferred embodiment of the multiple direction, reclining and stretching chair including the base structure A, the contact support structure B and the body support platform assembly C. The base structure A includes a first vertical wall 16 that is attached to a second vertical wall 18 with a first vertical cross support member 19a, a second vertical cross support member 19b and a horizontal cross support member 17. A first arm rest 12 is attached to the top of the first vertical wall 16 and a second arm rest 14 is attached to the top of the second vertical wall 18. Each of the vertical walls 16, 18 includes a corral defined by the oval shaped holes 30a, 30b. Typically, the corrals 30a and 30b are the same size and shape. However, the corrals 30a, 30b need not be the same shape and a corral is not necessary on each of the vertical walls 16,18. Instead, the axle 32 can extend into a single corral 30a or 30b.

The corral can be shaped in a number of possible configurations. FIGS. 12a and 12b illustrate several possible variations. FIG. 12a shows several possible shapes of the corral. The corral is shown as a vertical oval 305a and as a horizontal oval 305d. The corral may also be in the shape of a vertical slot 305b or in the shape of a circle 305c. FIG. 12b illustrates yet another possible variation in the corral shape. The corral in FIG. 12b is an amorphous shape 305e having an irregular shaped perimeter for limiting the motion of the axle 32. In particular, FIG. 12b shows semi-circular regions about the perimeter that correspond generally to the exterior shape of the axle 32. It is contemplated that the variation in shape of the corral from the illustrative shapes will not depart from the spirit and scope of the invention.

The contact support structure B includes a first arcuate shaped contact support member 20a and a second arcuate shaped contact support member 20b. A front roller 24 is positioned at the front between the two roller support members 20a, 20b and a rear roller 26 is positioned at the rear between the two contact support members 20a, 20b. It is contemplated that the contact support structure B could engage the body support platform assembly C with a set of linear contacts rather than with rollers. A cylindrically shaped contact support pivot 22 extends through each of the two contact support members 20a, 20b and through each vertical wall 16, 18 of the base structure A. Refer to FIG. 3 which shows the control rod 28 positioned in the center of the front roller 24. The control rod 28 follows the guide slots 29a, 29b. The guide slots 29a, 29b can include cutouts that allow the control rod to be locked into position in any of a multiple number of locations along the guide slots 29a, 29b. A control handle 27 can be attached to the end of the control rod 28 to secure and lock the contact support structure into any of the possible positions along the length of the guide slots 29a, 29b.

The body support assembly C includes a back platform 42 that is pivotally connected to a lumbar platform 44. The lumbar platform 44 is pivotally connected to the seat platform 46. As illustrated in FIG. 4, the body support assembly C may optionally include a head platform 40, pivotally connected to the back platform 42. In addition, an optional leg platform 48 may be pivotally connected to the seat platform 46. The pivotal connections used on the body support platform members may also include spring biased members at the pivotal connections. The pivotal connections may also include adjustable tensioning means for adjusting variable tension between the individual platform elements (For example, see FIG. 4). The variable tension can be fixed to lock the relative position between individual platform elements.

An axle 32 is shown rotatably attached to the lumbar platform 44 with two connector brackets 49. Each end of the axle 32 extends beyond each outer edge of the lumbar platform 44 and into each corral 30a and 30b.

FIG. 8 illustrates a second preferred embodiment wherein the contact support structure B rolls on the top of the horizontal cross support member 17.

FIG. 9 illustrates a third preferred embodiment wherein the contact support structure includes control rod segments 28a,28b,28c,28d that cooperate with guide slots 29a,29b,29c,29d. The guide slots 29a,29b,29c,29d limit the overall rotational motion of the contact support structure B as it rotates about the contact support pivot 22. The guide slots 29a,29b,29c,29d are cut through the guide structures 52a,52b. The control rod segments 28a,28b,28c,28d could also span the width between each contact support member 20a,20b. Control handles 27a,27b,27c,27d are releaseably attached to the control rod segments 28a,28b,28c,28d and allow the user to apply compression between the vertical walls 16,18, the contact support members 20a,20b and the guide structures 52a,52b. The applied compression fixes the position of the contact support structure B into the desired rotational position. Partial compression can also be applied with the control handles 27a,27b,27c,27d thereby reducing the speed of rotation of the contact support structure B. A control handle 27 may also be used to secure the position of the contact support structure B relative to the base structure A. The guide structures 52a,52b are optional and instead, the guide slots 29a,29b,29c,29d could be cut into the vertical walls 16,18. However, the guide structures 52a,52b provide additional structural stability to the vertical walls 16,18 and to the entire inventive chair.

FIGS. 10a and 10b illustrate a fourth preferred embodiment of the invention. The contact support members 20a,20b include pivot notches on the lower side. In FIGS. 10a and 10b, the contact support member 20a shows pivot notches 23a,23b that cooperate with the front and rear contact support pivots 22a,22b. Similar contact support notches can also be provided on contact support member 20b. The multiple contact support pivots 22a,22b allow the contact support structure B to pivot about each of the individual contact support pivots 22a,22b. The overall rotation movement can be limited by the travel of the control rod segments 28a,28b,28c,28d which travel within the respective guide slots 28a,28b,28c,28d.

FIG. 10a includes the first and second guide structures 52a,52b that are substantially attached to the vertical walls 16,18. FIG. 10b does not include the guides structures 52a,52b and instead, includes guide slots 29a,29b,29c,29d cut directly into the vertical walls 16,18. The guide slots 29a,29b,29c,29d may either pass completely or partially through the guide structures 52a,52b or vertical walls 16,18.

FIG. 10c illustrates a variation of the fourth preferred embodiment of the invention. The contact support pivots 22a,22b are attached to the contact support structure B. One of the ends of each of the contact support pivots 22a,22b extends into the corresponding guide slot pivots 36a,36b. The other ends of the contact support pivots 22a,22b extends into the other corresponding guide slot pivots 36c,36d. The guide slot pivots 36a,36b limit the overall motion of the contact support pivots 22a,22b. The contact structure is shown in the rear position D, the intermediate position E and the forward position F. It is contemplated that guide slot pivots may be used on one or both sides of the chair. Although the guide slot pivots 36a,36b,36c,36d are shown as vertical slots, alternative configurations are also possible. For example, the guide slot pivots 36a,36b,36c,36d may be curvilinear or oval in shape.

FIG. 11 illustrates a fifth preferred embodiment of the invention. The contact support structure B comprises two pairs of contact support members 35a,35b,35c,35d. The front pair of contact support members 35a,35b move independently from the rear pair of contact support members 35c,35d. The front contact support members 35a,35b include a front roller 24 that is mounted on a control rod 28. The control rod 28 travels within guide slots 29a,29b that are positioned on the vertical walls 16,18. Guide structures 52a,52b could also be used. An adjustment handle 27a is removeably attached to the end of the control rod 28 to provide compression between the vertical wall 16 and the front contact support members 35a,35b. A similar control handle could be connected to the opposite end of the control rod 28 outside of the opposite vertical wall 18. The rear contact support members 35c,35d include a rear roller 26. As with all of the inventive embodiments, the body support platform assembly C rests on the front and rear rollers 24,26. The rear contact support members 35c,35d include control rod segments 28c,28d that travel within guide slots 29c,29d. The guide slots 29c,29d are positioned on vertical walls 16,18. An adjustment handle 27c is removeably attached to the end of the control rod segment 28c to provide compression between the vertical wall 16 and the rear contact support members 35c,35d. A similar control handle could be attached to the control rod segment 28d outside of the opposite vertical wall 18.

Control handles 27x,27y may also be attached to provide adjustable compression on the front and rear contact support pivots 22a,22b.

It is also contemplated that the front contact support members include control rod segments that follow the guide slots 29a,29b instead of following the guide slots 29a,29b with the control rod 28 on which the front roller is mounted. If this alternative is used, the front roller would be mounted on a separate longitudinal axle member.

Operation:

Referring to FIGS. 1 and 2, the reclining and stretching chair includes a base structure A, a contact support structure B and a body support platform assembly C. The first and second vertical walls 16, 18 are structurally supported by first and second vertical cross support member 19a, 19b and by the horizontal cross support member 17. It is contemplated that alternative cross support members may be used to support the vertical walls 16, 18. It is also contemplated that alternative structural vertical members other than wall members that include the corrals may be substituted for the vertical wall members.

The contact support structure B pivots forward and rearward between the vertical walls 16, 18 about the contact support pivot 22. The contact support pivot 22 extends beyond the end of the first and the second side contact support members 20a, 20b and into the corresponding holes in the vertical walls 16, 18. In its rearmost position the contact support engages the upper surface of the horizontal cross support member 17. The rearward motion may be extended as shown in FIG. 3 by removing a section of the cross support member identified as the lower support slots 51a, 51b. The contact support members 20a, 20b can then extend through lower support slots 51a, 51b to increase the overall rearward motion of the contact support structure A. A control rod 28 is positioned at the center of the front roller 24. The control rod 28 may include nuts or other fastening means for securing the front roller within the slots 29a and 29b. For example, a control handle 27 is shown in FIG. 3.

The body support platform assembly C is comprised of multiple articulating panels that include a lumbar platform 44, a back platform 42 and a seat platform 46. The body support platform can optionally include a head platform 40 or a leg platform 48; or both. The angular position of the lumbar platform 44 can also be fixed to be parallel to the back platform 42 thereby creating a singular back platform. An axle 32 is allowed to rotate about the back side of the lumbar platform within connector brackets 49. Alternative means of attaching an axle 32 may also be used. The axle extends beyond each outer edge of the lumbar platform 44 into corrals 30a, 30b. The corrals are generally oval shaped openings positioned in the first and second walls 16, 18 of the base structure A. Alternatively shaped or configured corrals may also be used without departing from the inventive concept disclosed herein. Although the corrals are shown extending through the entire thickness of the vertical wall members 16, 18, it is possible to use corrals that do not extend completely through the thickness of the wall members. It is also possible to use a single corral in one of the walls of the base or attached near the center of the axle rather than using a corral in each of the walls. Yet further, it is possible to attach corrals to one or more of the substantially vertical wall members.

Because the corrals 30a, 30b are larger in diameter than the outer diameter of the axle 32, the axle 32 is free to rotate within the corral. In addition, the axle 32 is free to move in a horizontal or a vertical direction between the corral walls.

As the person sitting in the chair shifts their body weight, the body support platform assembly C moves. Because the axle 32 is attached to the body support platform assembly C and the axle 32 moves relative to the corrals 30a, 30b, the body support platform assembly C also moves relative to the corrals 30a, 30b and relative to the base structure A. Because the back platform 42 is rotatably attached to the top of the lumbar platform 44, the back platform 42 moves when the lumbar platform 44 moves. When the lumbar platform moves up or down, the back platform 42 also moves up or down. As the back platform moves up or down, it can also move across the freely rotating rear roller 26.

Similarly, because the seat platform 46 is rotatably attached to the bottom of the lumbar platform 44, the seat platform 46 moves when the lumbar platform 44 moves. When the lumbar platform 46 moves forward or backward, the seat platform 46 also moves forward or backward. As the seat platform moves forward or backward, it moves across the rotating front roller 24.

The body support platform assembly B can be moved from a generally upright position as shown in FIG. 1 to a reclined position as shown is FIG. 4. In FIG. 1 the contact support structure B is in the forward position while in FIG. 4, the contact support structure B is in the rearward position. As a result of the geometry and dynamic relationship between the contact support structure B and the body support platform assembly C, the body support platform assembly B remains stable throughout the range of forward or rearward positions of the contact support structure B. This allows a person to sit comfortably in the chair as the body support platform assembly C and the contact support structure remain in a state of equilibrium. It is also possible for a person to sit in the chair with the axle floating freely within the corrals. This surprising and unexpected advantage is caused by the effect of friction acting upon the contact support structure B, which acts as a fulcrum. If desired, the position of the contact support structure B can be fixed by securing the control handle or other retaining means on the control rod 28 (Shown in FIGS. 3, 4, 5). For example, a control handle 27 is shown in FIG. 3. The angular position of the control rod is shown as .THETA. in FIGS. 1 and 4.

When the contact support structure B is fixed in position relative to the support structure A, the body support platform assembly C can move about the front and rear rollers 24,26 and the lumbar platform 44 can move within the limited range provided by the corrals 30a,30b. The result is that the chair motion can be focused to stretch the back muscles while limiting the reclining motion.

When the body support platform assembly C is in an inclined position as shown in FIG. 4, the body support platform assembly C can move dynamically with the corresponding motion of the contact support structure B. Regardless of whether or not the contact support structure B is secured, the body support platform assembly C can move relative to the movement of the axle 32 within the corrals 30a, 30b. In FIG. 6 the lumbar platform 44 is shown in an upward, flexed position relative to the corrals 30a, 30b. The lumbar platform 44 can be placed in the upward, flexed position by the person who is sitting in the chair by extending their back when they are inclined on the body support platform C. If the person sitting in the chair continues to arch their back, they can create an extreme reverse angle between the lumbar platform 44 and the back platform 42 as shown as back platform assembly C in position G in FIG. 5. This extreme reverse angle can be effective to isolate, sooth and relax sore, fatigued or cramped muscles in a person's back while sitting or reclining in the chair.

As the lumbar platform 44 extends upward relative to the corrals 30a, 30b, a reverse angle is formed between the back platform 42 and the seat platform 46 as shown in FIG. 6. Wide ranges of angles can be formed between the interconnected back platform 42, lumbar platform 44 and seat platform 46. The variation in possible angles creates a very effective mechanism for stretching, strengthening and relieving tension in back muscles. In FIG. 5, for example the body support platform C is shown in the inclined position as I when the axle 32 and lumbar platform 44 are positioned at the bottom of the corrals 30a, 30b. As the axle 32 and lumbar platform 44 are moved upward within the corrals 30a, 30b, the body platform C forms a generally flat profile illustrated as position H. Position G shows the bent, reverse angle configuration of the body support platform assembly B when the axle 32 and lumbar platform 44 are positioned at the top of the corrals 30a, 30b and the back platform 42 is moved forward along the rear roller 26 (also refer to FIG. 7). The back platform 42 can also be moved forward and backward to increase the changing angle between the back platform 42 and the lumbar platform 44. This rocking motion and variation in angle between the back platform 42 and lumbar platform 44 creates a soothing, stretching effect on the back muscles.

The inventor also contemplates an alternative embodiment that includes a spring member that is substantially attached to the base structure. The spring member can extend between the horizontal support member and an upper position. An axle member can be attached to the spring at the upper portion of the spring member. The axle is rotatably attached to at least one section of the body support platform. The geometry and construction of the spring allows the axle to move within a predetermined area that defines a generally annular shaped corral. Because the axle is attached to a section of the body support platform assembly, the section of the body support assembly is allowed to move about the motion of the spring. The spring may be constructed of a variety of materials including but not limited to tempered steel or graphite reinforced carbon fiber or other resilient, supportive materials.

Because many varying and different embodiments may be made within the scope of the inventive concept herein taught, and because many modifications may be made in the embodiments herein detailed in accordance with the descriptive requirements of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense. The inventor also foresees applications for the mechanism including, but not limited to: passenger seating, beds, and specialty medical equipment such as wheelchairs, examination tables and the like.
