Abstract
An adjustment apparatus for a wheelchair back that can be used with various backs, that can be adjusted in a plurality of ways using a single adjustment point, and that can be adjusted without the use of tools. In another aspect, includes a support mechanism for mounting an adjustment apparatus for a wheelchair back that can be engaged using gravity, that provides at least one support point, and that can be utilized without the use of tools. Still another aspect of the wheelchair back assembly includes a mounting clamp that is simple in construction, that provides at least one support point, and that can be easily disassembled and adjusted to accommodate upright frame members of various diameters without the use of a tool.
Claims6
A mounting clamp assembly for attachment to a wheelchair post to engage a support mechanism for mounting a wheelchair back to the wheelchair post, the mounting clamp assembly comprising:
- a clamp block having a forward surface, a rear surface, a first side surface and a second side surface;
- a band configured to encircle a wheelchair post comprising opposed arms extending around the forward surface of the clamp block to define a space between the clamp block forward surface of the clamp block and the band to encircle a wheelchair post, the band being connected to the clamp block such that it can be positioned to an open position for attachment of the mounting clamp assembly to the wheelchair post and to a closed position wherein the band encircles the wheelchair post;
- a clamp fastener;
- and
- a support post extending from the clamp block, the support post providing at least one point of support for the support mechanism, wherein the support post is a cylindrical pin that extends perpendicular to the clamp fastener.
An apparatus for mounting a wheelchair back to a wheelchair post, comprising:
- a mounting clamp assembly for attachment to the wheelchair post, said mounting clamp assembly comprising at least one horizontally disposed support post and an attachment band for encircling the wheelchair post, and said attachment band being positionable from an open position for mounting on the wheelchair post to a closed position wherein the band encircles the wheelchair post;
- a mounting assembly comprising a hanger arm defining a hook for removable engagement of the mounting clamp assembly support post and a self-locking latch pivotally mounting to the hanger arm, the latch defining a locking notch;
- the latch being pivotal between a locked position in which the latch locking notch and the hook define a substantially closed hole and an unlocked position in which the hanger arm hook can be connected to or removed from the mounting clamp assembly support post;
- the latch being shaped and weighted such that the latch will move to the locked position under the force of gravity.
