- a sliding member longitudinally slidable within the control arm;
- the supporting arm further comprising a third pin, the third pin received in the sliding member and the slot of the control arm;
- the control arm is pivotally attached to the supporting member by a fourth pin;
- wherein when the sliding member and the third pin are at a first end of the slot, the wheel is held in a retracted position with respect to the supporting member;
