[0018]
[0019] The various embodiments of the present invention will hereinafter be described in conjunction with the appended drawings, wherein like designations denote like elements.
DETAILED DESCRIPTION
[0020] As discussed above, embodiments of the present invention relate to a wheelchair device and more particularly to a wheelchair assembly structured and arrange to equip a standard manual wheelchair with larger front wheels giving the user added leverage and control when maneuvering their chair.
[0021] Generally speaking, the Improved Wheelchair Assembly comprises a specially designed simple improvement upon the existing design of manual wheelchairs, in which the front wheels would be enlarged to a diameter of 9 inches from the now standard diameter of 8 inches.
[0022] This design enhancement could be incorporated into the design and production of new manual wheelchairs, orin existing chairs equipped with pin-locking, removable front-wheel assembliesproduced and sold as an add-on, aftermarket upgrade for existing wheelchairs. The enlarged front wheels would give the wheelchair user additional leverage and added maneuverability, with less effortand the Improved Wheelchair Assembly would also include a slightly lengthened foot-plate bar for additional stability.
[0023] Thus, although simple in conception and easily described, the Improved Wheelchair Assembly would represent a profound improvement in wheelchair design, greatly enhancing the wheelchair-user's ability to maneuver and navigate their chairand improving their own sense (and possession) of independent mobility. As such, the Improved Wheelchair Assembly should find a wide and enthusiastic market reception, first among those firms which produce manual wheelchairs, and then among the millions of consumersboth within the United States and around the worldwho depend on a manual wheelchair for mobility.
[0024] Referring to the drawings by numerals of reference there is shown in
[0025] Improved wheelchair assembly 100 comprising: main frame 110, seat 140; backrest 150; two spaced footplates 160; two spaced rear wheels 170; two spaced caster forks 180; and two spaced front castor wheels 190. Main frame 110 includes: two spaced armrests 116, two spaced hand grips 124, and two spaced footplate bars 164.
[0026] Wherein seat 140 is attached to frame 110. Wherein backrest 150 is attached to frame 110. Wherein two spaced footplates 160 are attached to respective two spaced footplate bars 164. Wherein two spaced footplates 160 are pivotally connected to respective two spaced footplate bars 164. Wherein two spaced footplate bars 164 are formed having a length greater than known wheelchair assemblies 100 and are adapted to provide increased stability to improved wheelchair assembly 100 as compared to known wheelchair assemblies 100.
[0027] Wherein two spaced rear wheels 170 are attached to frame 110. Wherein two spaced caster forks 180 are attached to frame 110. Wherein two spaced front castor wheels 190 are rotatably attached to respective two spaced caster forks 180. Wherein each of two spaced rear wheels 170 include push ring 174 attached thereto. Wherein two spaced caster forks 180 are adapted to releasably and rotatably hold front castor wheels 190 having a diameter of 9 inches. Wherein two spaced caster forks 180 are pivotally attached to frame 110. Wherein two spaced caster forks 180 are removably attached to frame 110. Wherein two spaced caster forks 180 are removably attached to frame 110 via pin-locking assembly 184.
[0028] Wherein said two spaced front castor wheels 190 are formed having a diameter of 9 inches. Wherein front castor wheels 190 are adapted to give a person manipulating improved wheelchair assembly 100 additional leverage and added maneuverability to manipulate improved wheelchair assembly 100 with less effort as compared to known wheelchair assemblies 100 having front castor wheels 190 having a diameter of 8 inches as shown in in-use condition 300 of
[0029] The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention.
