Arm assembly for a chair
First Claim
1. An arm assembly for a chair wherein the chair has a forward direction and a rearward direction, the arm assembly comprising:
- an armrest;
a support structure; and
a mounting device movably mounting the armrest to the support structure, the mounting device constraining the movement of the armrest relative to the support structure to movement in a substantially horizontal plane having two degrees of freedom defined by first and second transversely arranged axes lying within the substantially horizontal plane to move in a substantially planar fashion, the armrest being moveable independent along the first and second axes the movement being constrained so that the armrest cannot rotate in the horizontal plane.

Abstract
An arm assembly (24) is provided for a chair (12). The chair (12) has a forward direction and a rearward direction. The arm assembly (24) includes an armrest (26) and a support structure (28). A mounting device movably mounts the armrest to the support structure. The mounting device constrains the movement of the armrest (26) relative to the support structure to movement in a substantially horizontal plane having two degrees of freedom defined by first and second transversely arranged axes lying within the substantially horizontal plane. The armrest (26) thus move in a substantially planar fashion without changing the orientation of the armrest (26).

24. An arm assembly for a chair having a forwards direction and a transverse direction, said arm assembly comprising:
-
a longitudinal axis such that the arm assembly is adapted to be assembled with the chair with the longitudinal axis of the arm assembly corresponding substantially to the forward direction of the chair, a transverse axis arranged such that with the arm assembly assembled with the chair, the transverse axis corresponds to the transverse direction of the chair;
an armrest;
a support structure attachable to the chair, the armrest being mounted to the support structure by way of a mounting device such that the armrest is selectively moveable relative to the support structure forwards and backwards to adopt any one of a plurality of coordinate locations along the longitudinal axis and side to side to adopt any one of a plurality of coordinate locations along the transverse axis the side to side movement being independent of movement along the longitudinal axis, whereby the armrest is selectively positionable in any one of a plurality of discrete adoptable positions defined by its respective coordinate locations along the longitudinal and transverse axes, the mounting device incorporating a locking device to releasably lock the armrest in any one of the discrete adoptable positions. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)

45. An arm assembly for a chair having a forwards direction and a transverse direction, said arm assembly comprising:
-
a longitudinal axis such that the arm assembly is adapted to be assembled with the chair with the longitudinal axis of the arm assembly corresponding substantially to the forward direction of the chair;
a transverse axis arranged such that with the arm assembly assembled with the chair, the transverse axis corresponds to the transverse direction of the chair;
an armrest;
a support structure attachable to the chair, the armrest being selectively moveable relative to the chair forwards and backwards to adopt any one of a plurality of coordinate locations along the longitudinal axis and side to side to adopt any one of a plurality of coordinate locations along the transverse axis the side to side movement being independent of movement along the longitudinal axis, whereby the armrest is selectively positionable in any one of a plurality of discrete adoptable positions defined by its respective coordinate locations along the longitudinal and transverse axes; and
a locking device to releasably lock the armrest in any one of the discrete adoptable positions wherein the locking device is operable by a user'"'"'s hand positioned on the armrest. - View Dependent Claims (46, 47, 48, 49, 50)
