Abstract

The disclosed telescoping spring has application where space is limited and a long stroke is required. The spring may be utilized as a push-pull or over-the-center spring. Referring to Fig. 1, the spring comprises a fork 1 with limit tips thereon and a retainer 2 containing slots therein. In the telescoping mode (Fig. 1) the spring exerts light tension, depending on the preload requirements. In Fig. 2 the spring is fully extended and the limit tips of fork 1 fully traverse the slots of retainer 2. In this mode the spring is in tension. The spring remains in tension from preload to stop. Fig. 3 is a side view of the spring pivotally mounted by pin 3A to a sliding member 3 and by pin 4A to a stationary member 4.

Referring to Fig. 1, the spring comprises a fork 1 with limit tips thereon and a retainer 2 containing slots therein. In the telescoping mode (Fig.
1) the spring exerts light tension, depending on the preload requirements. In Fig. 2 the spring is fully extended and the limit tips of fork 1 fully traverse the slots of retainer 2. In this mode the spring is in tension. The spring remains in tension from preload to stop. Fig. 3 is a side view of the spring pivotally mounted by pin 3A to a sliding member 3 and by pin 4A to a stationary member 4.
