Abstract

Disclosed is a portable, adjustable table/desk configured to be removably attached to a wheelchair. The table/desk is utilized by an occupant of the wheelchair for engaging in paperwork, reading, or other activity. A variably tiltable tray is supported by parallel left and right side-panels and a rectangular, two-unit base plate 3. The undersurface of the tray 11 supports a linear, tube, each end embedded within countersunk hubs on the side-panels. The base plate 3 may be laterally widened or narrowed to correspond to accommodate the widths of various wheelchairs. Left and right chair mounts may be attached to the respective side-panels to facilitate direct attachment to suitable structural parts of wheelchairs not equipped with armrests. Alternatively, the left and right side-panels of the tray/desk may be attached to pliable left and right canopy clamps which flexibly grip the left and right armrests, respectively, of a wheel chair so equipped.

Dependent claims

A portable, table/desk device for removable attachment to various-sized wheelchairs, comprising:

(a) a left side-panel and a right side-panel, each being a solid, rectangular cuboid, each side-panel arranged vertically, side by side, with the interior-facing walls parallel to each other;
(b) a horizontally-oriented, laterally-adjustable base plate having its left edge orthogonally affixed to the interior wall of the left side-panel and its right edge orthogonally affixed to the interior surface wall of the right side-panel;
(c) a vertically tiltable tray comprising a top surface, an undersurface, a rear edge, and a front edge, the rear undersurface of the tray joined to a cylindrical shaft assembly, wherein
(i) the left end of the shaft assembly is rotatably embedded within a countersunk hub fabricated in the interior wall of the left side-panel and (ii) the right end of the shaft assembly is rotatably embedded within a countersunk hub in the interior wall of the right side-panel;
and
(d) a means for securing the left side-panel and the right side-panel to the left side and right side, respectively, of a wheelchair.

3 more elements

A portable, laterally and vertically adjustable table/desk 1 device having interchangeable structural components which enable temporary attachment of the device to wheelchairs, the table/desk comprising:

(a) a left side-panel and a right side-panel each being a solid, rectangular cuboid having a circular countersunk hub constructed on the interior surface of each respective side-panel;
(b) a laterally-adjustable base plate, the base plate being orthogonally attached at its left edge and right edge to the interior surfaces of the left and right side-panels, respectively;
(c) an angle adjuster rotatably attached to the front edge of the base plate;
(d) a tiltable, rectangular tray having a top surface, an undersurface, a rear edge, a rear flange, and a front edge, such that, with the table/desk compacted, the undersurface of the tray is parallel to, and abuts the upper edges of both the left side-panel and right side-panel;
(e) a “shaft assembly,” comprising (i) a linear tube, its left and right end nestled within the respective left and right countersunk hubs, (ii) the exterior of the tube joined to the undersurface of the tray;
(iii) identical left and right rods, placed end-to-end within the linear tube, and (iv) an elastic band connecting the outer ends of each rod;
and
(f) a means for securing the left side-panel and the right side-panel to the respective left side and right sides of a wheelchair.
