Handle device for foldable wheelchairs

1. A handle device for use with a collapsible wheelchair, the wheelchair positionable between a first working position and a second collapsed position, the wheelchair having first and second generally horizontal handlebars extending rearward to facilitate movement of the wheelchair, the handle device comprising first and second substantially “L”-shaped members, each “L”-shaped member having a lower portion and an upper vertically oriented portion, the lower portion adapted to receive the respective first and second horizontal handlebars therein, the upper portion extending substantially perpendicular to the lower portion, wherein the upper portion of each member upwardly extends beyond a height of the chair allowing the user to grasp each member without flexion of the torso, each “L”-shaped member having a locking device for securing each “L”-shaped member to the respective first and second handlebars of the wheelchair, the locking device including a slot contained on each lower portion of the first and second “L”-shaped members, and first and second opposing plates positioned along each side of the slot, each plate containing an aperture, the plates positionable towards one another by screw disposed within the apertures to lock the first “L”-shaped member to the first handlebar and the second “L”-shaped member to the second handlebar, wherein the wheelchair is permitted positioning between the first working position and the second collapsed position without any interference from either the first or the second “L”-shaped member.

2. The handle device of claim 1 wherein the lower portion of each “L”-shaped member is offset by an angle of less than 90 degrees from the respective upper portion.

3. A handle device for use with a collapsible wheelchair, the wheelchair positionable between a first working position and a second collapsed position, the wheelchair having first and second generally horizontal handlebars extending rearward to facilitate movement of the wheelchair, the handle device comprising:

first and second substantially “L”-shaped members, each “L”-shaped member having a lower portion and an upper portion offset from one another by an angle of less than 90 degrees, the lower portion adapted to receive the respective first and second horizontal handlebars therein, the upper portion of each member upwardly extending beyond a height of the chair allowing the user to grasp each member without flexion of the torso, wherein the wheelchair is permitted positioning between the first working position and the second collapsed position without any interference from either the first or the second “L”-shaped member, and wherein no portion of the handle device rearwardly extends past a vertically oriented plane positioned tangentially to a most rearward point of each wheel of the wheelchair; and

a locking mechanism to secure the first portion of each “L”-shaped member to the respective horizontal bar of the wheelchair, the locking mechanism including a slot contained on each lower portion of the first and second “L”-shaped members, and first and second opposing plates positioned along each side of the slot, the plates urged towards one another by a screw disposed therein to lock the first “L”-shaped member to the first handlebar and the second “L”-shaped member to the second handlebar.

4. An anti-theft device to prevent theft of a collapsible wheelchair, the wheelchair positionable between a first working position and a second collapsed position, the wheelchair having first and second generally horizontal handlebars extending rearward to facilitate movement of the wheelchair, the anti-theft device comprising first and second substantially “L”-shaped members, each “L”-shaped member having a lower portion and an upper vertically oriented portion, the lower portion adapted to receive and fixedly attach to the respective first and second horizontal handlebars by a locking mechanism, the locking mechanism including a slot contained on each lower portion of the first and second “L”-shaped members, and first and second opposing plates positioned along each side of the slot, the plates positionable towards one another by a screw disposable through the plates to lock the first “L”-shaped member to the first handlebar and the second “L”-shaped member to the second handlebar, wherein the upper portion extends upwardly beyond a height of the chair, wherein the height of the upper portion prevents the wheelchair to be placed within a vehicle, wherein the wheelchair is permitted positioning between the first working position and the second collapsed position without any interference from either the first or the second “L”-shaped member, and wherein no portion of the device rearwardly extends past a vertically oriented plane positioned tangentially to a most rearward point of each wheel of the wheelchair.

5. The anti-theft device of claim 4 wherein the lower portion of each “L”-shaped member is positioned less than 90 degrees from the respective upper portion.
