ABSTRACT:
A spring mechanism comprising an elongate cantilevered spring member extending along a longitudinal coupled at a first end to a first member and with a distal, second end of the spring member engaging a second member such that the spring member biases the first and second members relative to each other. The spring member has an unbiased condition and being resiliently deflectable generally normal to its longitudinal to assume deflected conditions from which the spring member inherently attempts to return to its unbiased condition. The longitudinal of the spring member preferably remains disposed in a flat plane in deflecting of the spring member between the unbiased condition and the deflected conditions. The spring member preferably has, in cross-section normal to its longitudinal, a shape including two legs disposed to lie in planes parallel the flat plane and joined by a bight normal to the flat plane. Preferably, the spring member is provided with resiliency substantially by the resilient deflection of opposed portions of the two legs towards and/or away from each other normal to the flat plane. The spring member preferably consists of plastic material and may be formed as an integral element injection molded from plastic as a unitary element together with the first member to which it is coupled.
