- FIG. 2 is a perspective view of a wheelchair with the retrofit adjustable seat of the present invention.
- FIG. 2a is a perspective view of another embodiment wheelchair with the retrofit adjustable seat of the present invention.
- FIG. 3 is a side view of the retrofit adjustable seat of the present invention.
- FIG. 3a is a side view of the retrofit adjustable seat of the present invention.
- FIG. 4 is a front view of retrofit adjustable seat of the present invention.
- Referring to the drawings, the
adjustable seat 10 which is here shown to include abase 12 which is connected to theside frame member 14 of a wheelchair W through use ofbrackets 16 which are fixably slidably connected to thebase 12. Thebase 12 may be formed of any resilient and strong material, preferably a light weight plastic, providing ease of portability along with strength. It is also contemplated that the present invention may be integrally formed as part of the wheelchair W or as a retrofit seat therefor. - In the case of a retrofit, FIGS. 3 and 4 depict the
brackets 16 as generally planar and elongated having anopen surface 18 therein and a terminal end 20 which is slightly arcuate.Screws 22 are provided of a size such that the threads thereof are less in diameter than theopen surfaces 18 and are received within threadedopen surfaces 24 of thebase 12 to enable connection of thebrackets 16 to thebase 12 When thescrews 22 are loosened, thebrackets 16 may be lengthwise positioned and then fixed in place by tighteningscrews 22 to thebase 12. - When the wheelchair W is opened the wheelchair
side frame members 14 typically open to a first predetermined spacing Thewheelchair side members 14 open to a second maximum spacing when a person sits on the wheelchair W. Thewheelchair side members 14 return to the first spacing when the person gets off the wheelchair W. - The
brackets 16 are positioned such that a distance between theends side members 14 in their maximum spaced relation The arcuate terminal ends 20 a and 20 b are in a fixed contact with thewheelchair side members 14 to hold theadjustable seat 10 in place until the person gets off of the wheelchair W, at which time thewheelchair side members 14 return to their first spaced relation to permit removal of the retrofitadjustable seat 10. Also, thescrews 22 can be loosened to aid the removal of the retrofit adjustable seat. - Means26 for elevating are provided and include a
base support member 28 connected to thebase 12,side support members top support member 32. Anend 33 ofside support member 31 is hingedly connected to anend 35 ofside support member 30. Anend 36 ofside support member 31 is hingedly connected totop support member 32 and anend 37 ofside support member 30 is hingedly connected tobase support member 28. Interconnectingmembers 38 are also provided, which interconnect ends 33 and 35 and each have a threadedopen surface 40 which coaxially align. A threadedbar 42 has opposite threaded ends and threads to opensurfaces 40. In this way, the side supportmembers bar 42. - The
elevating means 26 includes amotor 48 which is slidably connected to alinear race track 50 which in turn is connected to thebase 12. Themotor 48 includes a jointedrotatable shaft 60 extends from themotor 48 and fixably connects to the end of the threadedshaft 42. Astop 61 limits translational movement such that the threadedbar 42 does not thread beyond and out of the threadedopen surfaces 40. Themotor 48 can be powered by abattery 49 or other energy source, for example, which can be connected to thebase 12. Further,torsion springs 58 are fixably connected at their ends to supportmembers support members seat 44 is in a raised position. Thus, thesprings 58 aid to normally bias theseat 40 toward a raised position which in turn reduces the amount of work to be done by themotor 48. It is contemplated that other springs such as extension springs can be employed, for example, interconnecting the interconnectingmembers 38 to further aid in raising theseat 44. - The
seat 44 is connected to thetop support member 32. Theseat 44 preferably includes a bottom made of rigid material to support an individual when seated thereon as well as a soft cushion disposed on top of the bottom. Theseat 44 may be formed in any variety of configurations. For example, theseat 44 may be formed with a central raisededge portion 46 the purpose of which is to aid in leg comfort and support to the user as well as provide additional space therebeneath for accommodating themotor 48. - An
electronic controller receiver 70 is operably connected to themotor 48 andbattery 49 to cause activation of themotor 48 in forward and reverse directions Aremote control transmitter 71 is provided with an internal battery power source and equipped to send signals to thereceiver 70 to cause rotation forward, backward or to stop rotation. Optionally, a control can operably connect to themotor 48 andbattery 49 and can be disposed adjacent theseat 44 or on the wheelchair W. The control may be a hand operated switch or a joy stick mounted on a cord, for example, wherein moving the switch or joy stick one direction raises theseat 44 and moving the switch or joy stick in another direction lowers the seat. - A flexible expandable boot cover (side cover)64 can be optionally included to cover the
seat 10, elevatingmeans 26 andbase 12. Thecover 64 can be of any suitable cloth or synthetic material. - An
anti-pinch point cover 100 and is intended to compliment theadjustable seat 10. Theanti-pinch point cover 100 can be fabricated from a polymer, polyfoam and or cloth material for example. Thecover 100 may be formed of any flexible or resilient and strong material, preferably a light weight plastic and which provides ease of portability. Thecover 100 includes a pair ofside flaps 112 which can be connected to thebase 12 and are of a sufficient length and flexibility to remain draped over aside arm members 114 of wheelchair W. Further a leg flap 116 can be connected to thebase 12 and is of sufficient length and flexibility to remain draped overleg supports 118 of the wheelchair W.A back panel 120 can also be provided to connect to theseat 44 and extend upwardly to form a back rest therefor. - Finally, it is now contemplated by the inventor that the
ends 20 a and/or 20 b can be formed in with aslot 21 a, for example, and theside member 14 include a threadedbores 124 to receivelocking wing nuts 23 a. Thus, this provides for a substitute seat of the wheelchair W. In this embodiment, theend 20 b of thebrackets 16 can be loosened and slid inwardly such that theadjustable seat 10 can swing or pivot to a vertical position and hang byends 20 a. The present invention now provides a compact means for either retrofitting a conventional wheelchair or providing an integral wheelchair which includes the features of an improved height adjustable seat and means for collapsing the wheelchair with the eight adjustable seat attached thereto in a conventional manner, i.e, inwardly from the wheelchair's sides. - While the present invention has been set forth above in a preferred embodiment, it is contemplated that other modifications, improvements and derivations will be readily apparent to those skilled in the art. For example, it is contemplated that the
