The present invention relates to the field of health care devices, and more specifically, to a portable multifunction rehab station.
Physical therapy or physical rehabilitation is the treatment of physical injury or impairment through therapeutic exercise and the application of modalities that are intended to restore, facilitate and improve normal function or development. Such treatment, typically under the supervision and care of a licensed physical therapist, can be categorized into five different therapy regimes: resistance/strength training; balance and agility training; functional training; endurance/aerobic training; and flexibility training. Treatment under each of these regimes will typically include the use of several different pieces of equipment. For example, resistance/strength training usually incorporates application of resistance in opposition to the force of muscular contraction, the resistance being provided by tension via elastic, hydraulic or suspended mass (weights) components. Endurance/aerobic training includes light-to-moderate exercising for extended periods of time, such as rowing, walking or jogging which, when performed indoors, would require a rowing machine, treadmill or the like. The equipment for these therapies are often conveniently combined into one location, such as a spa or physical therapy center, but some patients may be unable, or perhaps reluctant, to travel even a short distance to the physical therapy equipment.
What is needed is a rehabilitation station that can be easily moved from one patient to another and provide a plurality of physical therapy exercises/modalities.
A portable rehab station includes a frame having left and right frame members that have bottom ends; left and right outriggers, each having a forward end and a rearward end, the left and right outriggers being connected at the bottom ends of the respective left and right frame members; a front, ground-engageable caster connected to the forward end of each of the left and right outriggers and a rear, ground-engageable caster connected to the rearward end of each of the left and right outriggers; and a standing assist apparatus including a leg brace and connection means for variably connecting the leg brace to the frame members and at variable heights relative to the bottom ends of the frame members.
In another embodiment, a portable rehab station includes left and right outriggers, each having a forward end and a rearward end, the left and right outriggers being pivotally connected at the bottom ends of the respective left and right frame members to pivot between retracted and expanded positions, the retracted position including the left and right outriggers being generally mutually parallel, and the expanded position including the left and right outriggers being spread out at an angle of between about six and ten degrees relative to each other. The portable rehab station further includes a front, ground-engageable caster connected to the forward end of each of the left and right outriggers and a rear, ground-engageable caster connected to the rearward end of each of the left and right outriggers; and includes an actuator assembly connected with the frame and operably connected with the left and right outriggers to selectively pivot the left and right outriggers between the retracted and expanded positions. The portable rehab station further includes and a standing assist apparatus including a leg brace and connection means for variably connecting the leg brace to the frame members and at variable heights relative to the bottom ends of the frame members
In addition, the portable rehab station includes left and right stabilizers, each having front and rear ends and at least one (and preferably one at each corner) ground-engageable grip pad, the left and right stabilizers are pivotably connected to respective left and right outriggers to pivot between an up, unlocked position and a down, locked position. The up, unlocked position includes the grip pads not being in engagement with ground and the portable rehab station being freely able to roll along ground via its casters, and the down, locked position includes the grip pads being in engagement with ground and the casters not being in engagement with ground.
The actuator assembly is operably connected with the left and right outriggers and the to left and right stabilizers to simultaneously pivot the left and right outriggers between the retracted and expanded positions and pivot the left and right stabilizers between the up, unlocked position and down, locked position.
It is an object of the present invention to provide an improved rehabilitation station.
Further objects and advantages will become apparent from the following description of the preferred embodiment.
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, and any alterations and modifications in the illustrated device, and further applications of the principles of the invention as illustrated therein are herein contemplated as would normally occur to one skilled in the art to which the invention relates.
Referring to
Frame 11 includes right and left upstanding frame members 31 and 32 and top, middle and bottom cross members 33-35, respectively, rigidly extending therebetween. Frame members 31 and 32 each include vertical beams 36 and 37 that, at their upper ends, angle approximately 90 degrees therefrom into upper, generally horizontal equipment support arms 38 and 39. In one embodiment, vertical beams 36 and 37 are fixed in length. In the embodiment of
At their bottom ends, vertical beams 36/37 are notched on their outsides to define clearance (at 43 and 44) (
Outriggers 12 and 13 are substantially mirror images of each other, and any differences therebetween will be pointed out, as appropriate. Referring to
Connector beam 54 is rigidly connected to and extends downwardly from rear caster arm 52, roughly midway between its forward and rearward ends 61 and 63, respectively. At its rearward end 65, long arm 53 is rigidly connected to and extends forwardly from the bottom end of connector beam 54 to a rigid connection at 69 at the outer side of pivot sleeve 51 and therefrom forwardly to its forward end 70. Front caster 55 is connected via bolt 71 to extend downwardly from a front caster arm 72, which is fixedly connected to the forward end 70 of long arm 54, as shown. The rigid connection from and among pivot sleeve 51, rear caster arm 52, connector beam 54, long arm 53 and back to pivot sleeve 51 forms a rigid quadblock 75 from which rearwardly extends rear caster arm 52 to rear caster 56 and from which forwardly extends long arm 53 to front caster 55.
Alternative embodiments are contemplated wherein the combination of pivot sleeve 51, rear caster arm 52, connector beam 54 and long arm 53 and rear and front caster arms 52 and 72 comprises other elements, including for example, a single, shaped structure that is held for pivotal connection by pivot brackets 45 and 46 and that holds front and rear casters 55 and 56 in the same positions relative to their pivotal mountings at 45 and 46.
In one embodiment, the distance from the pivot axis 50 of pivot sleeve 51 (in holes 48 and 49) to the bolt 62 of rear caster 56 is about 11 inches, and the distance from the axis 50 of pivot sleeve 51 to the bolt 71 of front caster 55 is about 38 inches. The spacing of casters 55 and 56 relative to each other and, of course, relative to their counterparts on the opposite, left outrigger 12, and their combined connection to frame 11 is selected so that outriggers 12 and 13 provide reliable stability to portable rehab station 10 while it is being transported (rolled along the floor on its casters) and during all anticipated exercise activities performed thereon, as described and suggested herein.
Stabilizers 14 and 15 are substantially mirror images of each other, and any differences therebetween will be pointed out, as appropriate. Stabilizer 15 includes a long bar 81, front and rear feet 82 and 83 and stabilizer mounting elements 84. Front foot 82 includes a footplate 86 fixed to the underside of the forward end 87 of long bar 81 and a pair of ground engaging grip pads 88 and 89 that are connected to the underside of footplate 86. Pads 88 and 89 are made of rubber or any similar material that is strong enough and durable enough to support and withstand the weight of the portable rehab station 10 and the forces to which it will be subjected, and to grip and resist lateral movement of portable rehab station 10 on the floor 23 when stabilizer 15 is engaged to the down, locked position 24. Pads 88 and 89 are generally disc shaped and removably connected to footplate 86 by any appropriate means such as bolts and nuts. Rear foot 83 is similar to front foot 82 and has a footplate 92 that is fixed to the underside of the rearward end 93 of long bar 81 and has ground engaging pads 94 and 95 that are connected to the underside of footplate 92. A link bracket 96 rigidly connected to long bar 81 and footplate 92 and extends upwardly from footplate 92 for pivotal connection with a stabilizer link, as discussed herein.
The stabilizer mounting elements 84 include mounting ears 101 and 102 and companion stabilizer mounting sleeves 103. Stabilizers 14 and 15 are pivotally mounted to the outside sides of the long arms 53 of their companion outriggers 12 and 13, respectively. At each of the opposing ends 87/93 of the stabilizer long bar 81 there are a pair of mounting ears 101 and 102 that receive and are pivotally connected to a mating stabilizer mounting sleeve 103. Stabilizer 14 is thus connected to its outrigger 12 to pivot about an axis 106 that is parallel to long arm 53 of outrigger 12, and stabilizer 15 is likewise connected to its outrigger 13. The sizes and configurations of the stabilizers, outriggers and their mating stabilizers (and their grip pads 88 and 89 and 94 and 95) are such that, when the stabilizers 14 and 15 are pivoted to their down, locked position 24, the outriggers, and thus the entire body of portable rehab station 10 connected to stabilizers 14 and 15, and most importantly, the casters 55 and 56, is lifted off of the floor and the entire weight of portable rehab station 10 is supported upon the grip pads 88 and 89 and 94 and 95.
Referring to
Index plate 119 defines open notches 131 and 132 that generally align with two outrigger holes 134 and 135 defined in control plate 120 when control plate 120 is rotated to a certain position. At its outer, generally opposing ends, control plate 120 defines stabilizer holes 137 and 138.
Actuator linkage assembly 111 includes four linkages—right and left outrigger links 141 and 142 and right and left stabilizer links 143 and 144, respectively. Right outrigger link 142 is pivotally connected at one end to control plate 120 at the upper and farthest stabilizer hole (134) (by appropriate means, which for a pivotal connection includes a bolt and nut, for example). (Such connections are well understood by those skilled in the art and are not further discussed). At its opposite, outboard end, right outrigger link 142 is pivotally connected to the rear portion of right outrigger 13. Such connection is here at a compatibly configured bracket 147 extending inwardly from connector beam 54. Left outrigger link 141 is similarly pivotally connected to and between the bracket 148 of left side connector beam 54 of the left outrigger 12 and the other, centrally located outrigger hole 135 of control plate 120.
The right stabilizer link 144 is pivotally connected at one end to control plate 120 at the nearest stabilizer hole 138. From there, stabilizer link 144 extends through the opening defined by (the right side) pivot sleeve 51, rear caster arm 52, connector beam 54 and long arm 53 and pivotally connects with the link bracket 96 of right stabilizer 15. The left stabilizer link 143 is similarly connected between control plate 120 at its other stabilizer hole 137 and the link bracket 149 of right stabilizer 14 (
Actuator input assembly 112 includes any suitable device connected to the rearward end of control rod 117 to permit the user to rotate control rod 117 and move portable rehab station 10 between the up, unlocked position 21 and the down, locked position 24. In one embodiment, the actuator input assembly 112 includes a foot operated device where the user's foot pushes down on a lever (such as at 151 and 152 in
In the up, unlocked position 21 (
In the expanded position where outriggers 12 and 13 are spread out by as much as 10 degrees (and more, in other contemplated embodiments), a wheelchair can be wheeled between the outriggers to enable the occupant to perform the exercises. Wheelchair seats and frames are typically about 20 inches width, plus another three to five inches for the wheels. In the up, unlocked position 21, the outrigger 12 and 13 are about 20 inches apart on the inside so that the overall wide enables portable rehab station 10 to be wheeled through doorways and down hallways. In the down, locked position 24, however, outrigger 12 and 13 spread out, at their forward ends to about 28 inches, which allows most wheelchairs to easily maneuver therebetween.
The second and equally important consequence of control rod 117 and control plate 120 rotating as a unit about central support rod 118 is that the stabilizer links 143 and 144 are pushed outwardly, which, by their pivotal connection to link brackets 96 and 149, rotates stabilizers 14 and 15 about their pivotal connections to outriggers 12 and 13, which forces the front and rear feet 82 and 83 and their grip pads to 88, 89, 94 and 95 of the stabilizers to engage the floor and lift portable rehab station 10 up off its casters. Portable rehab station 10 is now substantially immovable given its weight and the high frictional coefficient between the grip pads and most floors.
Also of considerable importance are the location of the outrigger holes 134 and 135 relative to the central support rod 118 and the outer connections of outrigger links 141 and 142. As seen in
The connections of outrigger links 141 and 142 at holes 134 and 135 include bolts or some appropriate fastener that extends out forwardly of control plate 120. These bolts engage with notches 131 and 132 and define the limit of counterclockwise rotation of control plate 120, which thus prevents damage from the outrigger links 141 and 142 hitting the control rod 117.
Portable rehab station 10 contains other features readily shown in the figures. For example, portable rehab station 10 includes a combination table top 171, seat 172 and cushion 173 for use in the various rehab exercises. Arms 174 and 175 are pivotally mounted to a carriage 176 that rides up and down a track 179 and 180. The vertical position can be set by a pin and hole arrangement (at 181/182). The arms 174 and 175 can support table top 171, and when arms 174 and 175 and their carriage are moved to a lower position, the table top 171 becomes a seat for a rehab patient not seated in a wheelchair. The width of the arms 174 and 175 are adjustable along the horizontal support bar 183 via adjustment mechanisms 184 and 185. The arms are pivotally mounted at the adjustment mechanisms to they can be pivoted up and out of the way for certain exercises such as walking on a treadmill (not shown) that would be provided with portable rehab station 10. The cushion is useful in the down position for bracing one's knees thereagainst, and for other exercises at other heights.
In the embodiment of
Alternate configurations are contemplated for the configuration of stabilizers 14 and 15 so long as it is pivotally mounted to outriggers 12 and 13 to pivot between the up and the down positions where ground engaging pads such as pads 88, 89, 94 and 95 engage the ground and the rest of the portable rehab station connected to stabilizers 14 and 15, and particularly the casters 22, is lifted off the ground so that portable rehab station 10 rests solely upon the pads.
Referring to
Leg brace 212 includes a brace frame 218 and a leg pad 219. Frame 218 is made of metal or any suitably strong material and has left and right bars 220 and 221 and cross beams 222 and 223 rigidly connected and extending therebetween, as shown. At the top ends, left and right bars 220 and 221 angle forwardly (in its mounted position 229 supported by frame 11) to form left and right hand grips 225 and 226, respectively, which are covered by a comfortable hand grip material, such as rubber.
Leg pad 219 is made of any resilient foam or similar material and covered with leather, vinyl or other similar material to provide a comfortable cushion against which a user's legs—and particularly his/her knees—can be positioned and braced against movement toward the rear of portable rehab station 210. Pad 219 is preferably U-shaped with a center section 230 of one thickness 231 and opposing left and right guide sections 232 and 233, which have a second, greater thickness 234. Left and right guide sections 232 and 233 extend rearwardly farther than center section 230 to form left and right inner walls 238 and 239, which function to position and keep the user's knees located in the desired, mostly central location. In one embodiment, pad 219 is about 21 inches wide, about 15 inches high and about 3 inches thick in center section 230 and about 6 inches thick in the opposing outer sections 232 and 233. In the mounted position 229 (shown in
Pad 219 and grips 225 and 226 are sized and configured to enable a user to easily grasp handles 225 and 226 and maneuver it in and out of the mounted position 229 and to adjust the pad 219, as described below.
Connection means 213 includes left and right support arms 244 and 245 and left and right cantilever pocket assemblies 246 and 247. Support arms 244 and 245 are minor images of each other, and cantilever pocket assemblies 246 and 247 are mirror images of each other, thus only one of each will be described with any difference therebetween being noted. Right support arm 245 is rigidly connected to and extends rearwardly from an upper portion of right bar 221, as shown. Defined in the top and mostly rearward edge of right support arm 245 are registration means which includes a series of spaced apart notches 249. In one embodiment, there are five notches 249 spaced about an inch apart. Alternative embodiments are contemplated wherein there are more or fewer notches 249, and their spacing is may also vary to provide whatever degree of positioning variability may be desired.
Right cantilever pocket assembly 247 here includes a plate 252, spacer rods 253 and 254 and connector bar 255. One spacer rod 253 extends inwardly from and the top and rear of plate 252, while the other spacer rod 254 extends inwardly from and at the bottom and front of plate 252. Connector bar 255 extends from the top, rear rod 253 to the lower, front rod 254, as shown. This configuration forms a pocket 257 that is sized and configured to receive the corresponding right support arm 245 therethrough for longitudinally adjustable support thereof. Right cantilever pocket assembly 247 is mounted to the inside surface of right frame member 31, and left cantilever pocket assembly 246 is mounted in lateral mirror image fashion to the inside surface of the left frame member 32, as shown in
The direct distance 258 between spacer rods 253 and 254 is greater than the height 259 of the support arms 244 and 245 so that a support arm 245 can easily pass through pocket 258 when done so at an angle 262 above horizontal 263 (zero degrees). But then, when the right support arm 245 is in the pocket 258 and rotated back to horizontal, and with a notch 249 registered directly below the upper spacer rod 253, and the lower edge 264 of right support arm 245 engages and sits atop the lower spacer rod 254, right support arm 245 is in a horizontal position, and consequently (with both left and right support arms 244 and 245 in their pockets 257) leg pad 219 is in the mounted position 229.
Thus, to mount leg pad 219, the user first removes the table top 171 and pivots the arms 174 and 175 to the up position, if necessary, and raises the carriage 176 to the desired upwardly located position, as shown in
In use, with the leg pad 219 in the mounted position 229, a user then steps up to the so-configured portable rehab station 210 with his knees positioned against leg pad 219 and his chest against the upper pad 270 of carriage 176. The upper retention member 214 (
While strap 273 is shown as one length, alternative embodiments are contemplated wherein strap 273 is made of any suitable material and is provided with adjustability, as is well known in the art.
The adjustability provided by the notches 249 allows leg pad 219 to be mounted whereby the front surface 280 of its central section is generally coplanar with the front surface 281 of the upper pad 270. It is contemplated that the notches be spaced to allow leg pad 219 to be moved forwardly about six inches, but other dimensional variability is also contemplated. This allows the user to be positioned in a variety of different positions.
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
