Adjustable armrest for attachment to an armchair
First Claim
1. An adjustable chair armrest assembly for attachment to an armchair, the armchair having a horizontal arm, a seat, and a pair of vertical braces having bores at each end thereof, extending between the arm and the seat, the assembly comprising:
- a flat work surface having an underside, an inner edge, and an outer edge, wherein upon attachment of the work surface to the armchair the inner edge of the surface is positionable adjacent to the armchair;
an upper horizontal support member attached by at least one upper support hinge to the underside of the work surface, at the inner edge of said surface, the at least one hinge extending between the support member and the underside of the work surface, wherein the at least one hinge allows the work surface to pivot downward about the hinge, the upper support member capable of selectively engaging the pair of vertical armchair braces;
a lower horizontal support member having a front surface, the support member capable of selectively engaging the pair of vertical armchair braces at a point below the upper horizontal support member; and
a vertical support member extending between the underside of the work surface and the lower horizontal support member.

Abstract
An adjustable armrest assembly for attachment to an armchair. The armrest assembly includes a flat work surface, an upper horizontal support member, and a lower horizontal support member. A vertical support member extends diagonally between the lower horizontal support member and the underside of the work surface, at the outer edge of the surface. The vertical support member has a mid point crease. A mid point hinge is attached to the vertical support member at the mid point crease. The vertical support member further comprises a top hinge extending between the top edge of the vertical support and the underside of the work surface. The bottom edge of the vertical support member rests on the front surface of the lower horizontal support member, and is wedged between the member and a block attached to the front surface of the member.

6. A method of utilizing an adjustable armchair armrest, on an armchair, using the armrest comprising a flat work surface having an underside, an upper horizontal support member having at least one upper support hinge extending between the support member and the underside of the work surface, a lower horizontal support member having a front surface and a block attached to the front surface of the lower horizontal support, and a vertical support member extending between the underside of the work surface to the front surface of the lower support member, the vertical support member having a mid point crease dividing the support member into an upper portion and a lower portion, wherein a mid point hinge is positioned at the mid point crease and extends between the upper portion and the lower portion, comprising the steps of:
-
attaching the armrest to the armchair;
extending the work surface horizontally by pivoting said surface about the at least one upper support hinge;
unfolding the vertical support member by pivoting the upper portion and the lower portion about the mid point hinge;
extending the vertical support member diagonally from the work surface to the lower horizontal support member; and
wedging the bottom edge of the vertical support member within a space created between the lower support member and the block. - View Dependent Claims (7)
aligning the upper horizontal support member and the lower horizontal support member with the vertical braces of the armchair; and
engaging a bolt through the bores of the upper and lower support members, and through the corresponding bores of the vertical braces.
