The present invention generally relates to a stretching table and, more particularly, to a stretching table that provides targeted stretching for lower extremity, lower back and/or lower abdominal muscle groups in a human patient.
Various types of stretching tables, including different physical therapy tables, exam tables and treatment tables, are known in the art. Although such tables may enable human patients to stretch different muscles, they are typically limited in terms of the different ways in which they can target and isolate lower extremities, lower backs and/or lower abdominal muscle groups. Furthermore, providing a stretching table that is both sturdy and durable, yet is small and compact enough so that it can be used in a number of office and other settings, can be challenging.
According to one aspect, there is provided a stretching table for targeted stretching of a human patient, comprising: an upper body support member; a connection mechanism connected to the upper body support member; and first and second lower body support members connected to the connection mechanism, wherein the first and second lower body support members can move, with respect to the upper body support member, via the connection mechanism.
According to various embodiments, the stretching table may further include any one of the following features or any technically-feasible combination of some or all of these features:
According to another aspect, there is provided a method of operating a stretching table for targeted stretching of a human patient, the stretching table comprising: an upper body support member; a connection mechanism connected to the upper body support member; and first and second lower body support members connected to the connection mechanism, wherein the first and second lower body support members can move, with respect to the upper body support member, via the connection mechanism; the method comprising the steps of: rotating or swiveling at least one of the first or second lower body support members side-to-side; and rotating or tilting at least one of the first or second lower body support members up and down.
Preferred embodiments will hereinafter be described in conjunction with the appended drawings, wherein like designations denote like elements, and wherein:
The stretching table disclosed herein provides targeted stretching for lower extremity, lower back and/or lower abdominal muscle groups in a human patient and is capable of being manipulated in any number of different configurations. In particular, the stretching table is capable of providing targeted stretching so that certain muscle groups can be stretched, rehabilitated and/or worked on individually. Some non-limiting examples of muscle groups that may be targeted by the present stretching table include: in the lower extremities, the bilateral hamstrings, the abductors, and the deep hip flexors; in the lower back, the multifidus, the longissimus, the spinalis, and the quadratrus lumborum; and in the lower abdominals, the bilateral rectus abdominis and the bilateral external obliques. Of course, the stretching table of the present application may be operated or manipulated in any number of different ways and configurations and is not limited to targeted stretching of the aforementioned muscle groups, as other muscle groups and/or combinations of muscle groups may be stretched as well.
Turning now to
Base member 12 provides the stretching table 10 with a sturdy base or foundation for supporting the rest of the table. According to the non-limiting example shown in the drawings, the base member 12 is a flat, horizontal metal piece (e.g., one made from steel, aluminum, etc.) that rests on the ground and has a generally rectangular shape that is longer in a length direction X than in a width direction Y. At a forward end 40 of the stretching table the upright member 14 is attached to the base member 12, and at a rear end 42 of the stretching table the base member 12 includes a plurality of legs 44. It should be appreciated that the base member 12 is not limited to the exemplary embodiment shown in the drawings and may instead have any number of different configurations, including ones that are: rectangular shaped (with legs at the forward end, legs at the rear end, legs at both the forward and rear ends, legs at neither end, etc.), square shaped, oval shaped, circular shaped, or irregularly shaped, to cite a few examples. In addition, the base member 12 may include through holes along its perimeter so that the base member 12 and, thus, the entire stretching table 10, can be securely bolted or otherwise fastened to the floor.
Upright member 14 supports the upper and lower body support members so that the patient can be elevated and supported at a desirable height. In one example, the upright member 14 is a tapered and forward-leaning metal tower or column and includes a lower end 50 and an upper end 52. The tapered configuration causes the upright member 14 to be slightly larger in cross-section at the lower end 50, where the member is welded, bolted and/or otherwise attached to the base member 12, than towards the upper end 52, where it is welded, bolted and/or otherwise attached to an underside of the upper body support member 16. The cross-sectional shape of the upright member 14 may be rectangular so that its longer in a length direction X than it is in a width direction Y; such a cross-sectional configuration may be advantageous in terms of strengthening the upright member 14 and helping to support the weight of the patient, since much of that weight is cantilevered out on the lower body support members 18, 20 that extend in the length direction X. The forward-leaning configuration of the upright member 14 is also useful in terms of supporting the weight of the patient. In the illustrated example, the upright member 14 is forward-leaning such that its upper end 52 extends outwardly in the length direction X, beyond an edge of the forward end 40 of the base member 12 (this is best seen in
Upper body support member 16 is designed to support an upper body or torso of a human patient, or at least portions thereof. According to the illustrated example, the upper body support member 16 is a flat, horizontal cushioned surface that is sized and shaped to comfortably support portions of a patient's upper body (e.g., the upper body support member 16 may support a patient's upper body from the head to around the umbilicus). The upper body support member 16 may be oval or rectangular in shape, as shown in the drawings, or it can have a different shape and/or size. The upper body support member 16 may include a support frame (not shown), such as a metal or plastic framework extending around the perimeter and/or across the interior of the support member, a flat support piece (not shown) in the form of a board or the like that is mounted to the support frame, as well as a cushioned outer layer 60 (e.g., one made from a foamed material) that is wrapped and pulled tight around the support frame and/or flat support piece so that the patient has a soft surface to lay on. It is possible for the cushioned outer layer 60 to be substantially flat or planar on its upper surface, as illustrated in the drawings, or it can be provided with the contours of a human patient's upper body portions, such as grooves and mounds designed to comfortably compliment the typical curves of a body. In one example, the upper body support member 16 is rigidly and stationarily attached to the elevated member 14; in another example, the upper body support member 16 may rotate or pivot with respect to the elevated member 14.
First and second lower body support members 18, 20 are designed to support a lower body or lower extremities of a human patient. In one example, the lower body support members 18, 20 are flat, elongated cushioned surfaces that are sized and shaped to comfortably support portions of a patient's lower body, such as the legs. The first and second lower body support members 18, 20 are adjustably connected to the upper body support member 16 via the connection mechanism 22 and can be independently adjusted or manipulated, as will be explained in greater detail. Similar to the upper body support member 16 described in the previous paragraph, each of the first and second lower body support members 18, 20 may include a support frame (not shown), such as a metal or plastic framework extending around the perimeter and/or across the interior of the support member, a flat support piece (not shown) in the form of a board or the like that is mounted to the support frame, as well as a cushioned outer layer 62, 64 (e.g., one made from a foamed material) that is wrapped and pulled tight around the support frame and/or the flat support piece to provide a soft surface. It is possible for the cushioned outer layer 62, 64 to be substantially flat or planar on its upper surface, as illustrated in the drawings, or it can be provided with the contours of a human patient's lower body, such as grooves or channels designed to comfortably receive the curves of a leg. When aligned in the length direction X (as shown in
Connection mechanism 22, which is best illustrated in
The first swivel arm 70, the first tilt arm 72 and the first bolt 74 all work together to adjustably support the first lower body support member 18 so that it can swivel side to side, tilt up and down and/or otherwise move in some other manner. Starting with the first swivel arm 70, it is preferably a solid metal piece (e.g., one made from steel, aluminum, etc.) that is in the shape of a half wishbone and includes a swivel hole 90 near one end, a tilt hole 92 near the other end, and a bend or turn 94 towards the middle of the arm in between holes 90 and 92. The swivel hole 90 is preferably a through hole that extends all the way through the first swivel arm 70 along a swivel hole axis A and is sized to rotatably accommodate the primary attachment bolt 82, whereas the tilt hole 92 extends at least partially through the first swivel arm 70 (it could extend all the way through, but it does not have to) along a tilt hole axis B and is sized to rotatably accommodate the first bolt 74. In one example, the swivel hole axis A is aligned so that it is generally parallel to a height direction Z of the stretching table 10, and the tilt hole axis B is aligned in a plane that is generally parallel to a plane containing the length direction X and the width direction Y. The swivel hole axis A and the tilt hole axis B may be perpendicular to one another. The bend or turn 94 is configured so that the other end of the first swivel arm 70, which includes the tilt hole 92, is bent inwards towards the second swivel arm 76, as opposed to being bent outwards away from the second swivel arm. This inward bend 94 enables the first and second swivel arms 70, 76 to be attached at a common location (i.e., the primary attachment bolt 82), but also be able to spread out from one another so that the first and second lower body support members 18, 20 can be aligned side-by-side in a generally parallel manner (see, for example, neutral position in
First tilt arm 72 is also preferably a solid metal piece (e.g., one made from steel, aluminum, etc.) and includes a tilt hole 100 near one end, a mounting section 102 near the other end, and a bend or turn 104 that is located towards the one end but is in between hole 100 and mounting section 102. The tilt hole 100 extends through the first tilt arm 72 along the tilt hole axis B and is sized to rotatably accommodate the first bolt 74. As illustrated in
First bolt 74 and primary attachment bolt 82 are preferably solid metal bolts or pins (e.g., ones made from steel, aluminum, titanium, etc.) that extend through corresponding holes in various pieces of the connection mechanism 22 and enable those pieces to swivel, tilt, rotate, hinge, etc. According to the example shown in the drawings, bolts 74 and 82 have a stem portion 110, 112 and a head portion 114, 116, respectively. The size, shape, configuration, etc. of the bolts 74, 82 may differ from those shown and may be altered to meet the specific geometry of the hole and/or part into which they fit. It is even possible to use a cotter pin or the like so that bolts 74 and 82 are maintained in their respective holes and do not inadvertently back out.
In a manner similar to that just described, the second swivel arm 76, the second tilt arm 78 and the second bolt 80 all work together to adjustably support the second lower body support member 20 so that it can swivel side to side, tilt up and down and/or otherwise move in some other manner. The second swivel arm 76, second tilt arm 78, and second bolt 80 may include a similar set of holes, hole axes, bends or turns, mounting sections, ends, angles, stem portions, head portions, etc. as those described in the preceding paragraphs. For purposes of conciseness, a second duplicate description has been omitted, however, the description above applies equally to the second swivel arm 76, the second tilt arm 78 and the second bolt 80. As shown in
Drive mechanism 24 enables a user, whether the user is the patient or a practioner, to adjust the position and/or orientation of the first and/or second lower body support members 18, 20 so that targeted stretching for lower extremity, lower back and/or lower abdominal muscle groups can be achieved. The drive mechanism 24 may be manual, electric, pneumatic and/or hydraulic in nature, depending on the needs of the particular application. According to one possibility, the drive mechanism 24 is an electric drive mechanism and includes one or more electric motor(s) 120, such as servo motors, that are operatively coupled to the first and second swivel arms 70, 76, as well as the first and second tilt arms 72, 78. The drive mechanism 24 may include a separate electric motor at each of the pivoting joints (i.e., separate motors at the connection of the first and second swivel arms 70, 76 via primary attachment bolt 82, at the connection of the first swivel and tilt arms 70, 72, and at the connection of the second swivel and tilt arms 76, 78); it is also possible for the drive mechanism to include only a single electric motor with various output linkages so as to be able to control the different pivoting joints. Other motor and/or output arrangements are certainly possible.
Control mechanism 26 allows the user to adjust, manipulate and/or otherwise precisely control the drive mechanism 24, and hence the position of the overall stretching table 10, in any number of different ways. The control mechanism 26 may include a remote control device 124. In one embodiment, the remote control device 124 is a standard hand held controller that is connected to the drive mechanism 24 via a wired connection 126 or is wirelessly connected, such as via Bluetooth or some other short-range wireless protocol. In a different embodiment, the remote control device 124 is provided in software as an “app” or similar software package that can be installed on a user's mobile phone, tablet, laptop and/or other device. In yet another embodiment, the remote control device 124 is provided as part of a larger computer terminal or system that can be connected to one or more stretching tables 10, such as in a hospital or clinic-type setting, and operates them accordingly.
It should be appreciated that the present stretching table is not limited to the various examples and embodiments provided herein. Numerous alternatives are possible and are intended to be part of the present disclosure.
In operation, a user is able to adjust or manipulate the stretching table 10 to provide targeted stretching for lower extremity, lower back and/or lower abdominal muscle groups. It is possible for the user to be the patient such that no other person is needed to cycle through the targeted stretching routine (e.g., if the stretching table 10 is installed in the patient's home); it is possible for the user to be a practioner who is with the patient and is interacting with the patient as they progress through the targeted stretching routine (e.g., if the stretching table 19 is installed at the practioner's clinic or facility); or it is possible for the user to be a practioner that is located remotely from the patient and is controlling the stretching table 10 remotely via the control mechanism 26, to cite a few possibilities.

Referring now to
For each of the various configurations, a user may engage the control mechanism 26 and make selections indicating that they wish to have one or both lower body support members 18, 20 tilted upwardly or downwardly. The control mechanism 26 then sends one or more control signals to the drive mechanism 24, which interprets and/or applies the corresponding commands so that electric motor 120 is driven accordingly. This, in turn, causes the first and second tilt arms 72, 78 to tilt (either up or down) about the tilt hole axis B, thereby causing the first and/or second lower body support members 18, 20 to incline or decline and stretch the patient. Similarly, the patient may engage the control mechanism 26 to swivel or rotate the first and/or second lower body support members 18, 20 in an inwardly or outwardly direction. This causes the control mechanism 26 to send one or more control signals to the drive mechanism 24, which interprets and/or applies the corresponding commands so that electric motor 120 drives the first and second swivel arms 70, 76 to swivel or rotate (either inwardly or outwardly) about the swivel hole axis A. Of course, any number of other manipulations and/or adjustments may be made to the stretching table 10, as it is certainly not limited to the positions shown in the drawings.
It is preferable that the upper body support member 16 stay stationary as the lower body support members 18, 20 are being adjusted. This provides a sturdy base or arrangement for the stretching table 10, while at the same time limiting the moving parts to just the lower body support members 18, 20 and the drive mechanism 24. If the swiveling motion of an individual lower body support member about the swivel hole axis A is considered one degree of freedom, and the tilting motion of an individual lower body support member about a tilting hole axis B is considered one degree of freedom, then the stretching table 10 provides for at least four degrees of freedom (two degrees of freedom per lower body support member).
