Abstract
A table assembly for mounting and demounting to frame members of a wheelchair, said assembly having a table member with open ended locking slots to engage tubular leg and frame members; and elongated braces on the underside of the table member which can be lowered to engage tubular horizontal frame members on the wheelchair. The table member is provided with mounting means and an easel assembly which can be pivoted to selectively fixed positions. The table member is also provided with three upright walls and openable and closable leaves so the working surface can be extended when open, and the assembly can be carried as a box when closed.
Claims10
A mountable and demountable table assembly for a wheelchair which has a pair of vertical leg members extending to arm rest members and horizontal frame members which are substantially parellel to said arm rests, including
- a planar table member having an inner edge, spaced side edges and an outer edge,
- leg braces pivotally mounted to the underside of the table member adjacent to the outer edge, said braces having looped and biased seats to engage frame member portions of the wheelchair,
- locking means associated with the table member adjacent the inner edge to engage frame members at a level higher than the frame portions engaged by the leg braces,
- said locking means including an inner edge locking slot having an open end located along said inner edge to engage a vertical leg member adjacent the arm rest member, and a side edge locking slot having an open end located along one of said side edge for engaging the other of said vertical leg members,
- mounting means positioned on said planar table member,
- and an easel assembly joined to said mounting means,
- said easel assembly including a pivotally mounted base member, an elongated easel member, and an elongated adjusting means to fix the elongated easel in a selectively pivoted position.
A mountable and demountable table assembly which includes the features of claim 11 wherein said locking means further includes a pair of pivotal braces adjacent said inner edge, said pivotal braces being shorter than said leg braces, the free ends of said braces having curved and biased loops to frictionally engage cylindrical frame members at a level higher than the frame members engaged by said leg braces, and the pair of braces having a length related to the length of the leg braces so that the table member is level when all the braces are operatively engaged with the frame members of the wheel chair.
