A nesting chair having a support frame having a back support portion, a pair of front legs having an stopping member for load bearing in an active position, a pair of rear legs and a rear support. The nesting chair further includes a seat having a top side and an under side for engagement of the stopping member, a support member mounted to the under side of the seat having an engaging end for pivotally engaging the rear support and slidably disengaging from the rear support; and a holding member mounted to the under side of the seat for engaging, and holding the seat to the nesting chair relative to the rear support member in an active position.

A stability maintaining and shock absorbing bicycle front fork assembly comprises a steering spindle for pivotal mounting on a bicycle front frame. A single arm fork member having top and bottom ends is rigidly attached adjacent its top end to tope and bottom crown members rigidly attached to the steering spindle. A swing arm assembly is mounted on the single arm fork member to define a swing arm pivot axis oriented generally parallel to the displaceable axis of rotation, for pivotal movement of the swing arm assembly between a forward position, at which the swing arm assembly extends downwardly and rearwardly from the swing arm pivot axis and wherein the displaceable axis of rotation is disposed forwardly of the steering axis and rearwardly of the swing arm pivot axis, and a trailing position at which the displaceable axis of rotation is disposed closer to the steering axis than when in the forward position. A hub defining the displaceable axis of rotation is disposed on the swing arm assembly so as to permit mounting of a front bicycle wheel thereon. A pivotally jointed linkage arm assembly is pivotally mounted at its ends to the single arm fork member and to the swing arm assembly, respectively, and includes a lower linkage arm and an upper shock linkage arm assembly pivotally connected one to the other. A shock absorber is operatively mounted between the single arm fork member and the upper shock linkage arm assembly, to bias the swing arm assembly to its forward position.

A stability maintaining shock absorbing bicycle front fork and trailing arm assembly comprises a hub member attached to the steering spindle for pivotal movement therewith. Left and right fork members are attached adjacent their top ends to the hub member. Left and right trailing arms are pivotally mounted one on each of the left and right fork members. A bicycle wheel mounting member is disposed on each of the trailing arms so as to permit mounting of a front bicycle wheel thereon. In use, the left and right trailing arms are concurrently pivotally movable between a forward position whereat the axis of rotation of the front bicycle wheel mounted on the trailing arm assembly is disposed forwardly of the steering axis and between the steering axis and the common pivot axis, and a trailing position whereat the axis of rotation is disposed closer to the steering axis than when in the forward position and is also displaced vertically closer to the common pivot axis than when in the forward position. A variable length shock absorber is securely mounted at its top end on the hub member. A linkage arm is pivotally mounted at its bottom end to one of the trailing arms, and is pivotally mounted at its top end to the shock absorber. Alternatively, a linkage arm may comprise a variable length shock absorber. A spring biases the shock absorber to its extended configuration the trailing arms to their respective forward positions.
