Spring retainer clip
View Patent ↗A spring restraining clip mounts the axial terminus of a coil spring on the chassis via a spring seat. At least two of three spring restraining members that are circumferentially spaced on the spring restraining clip are the open type of spring restraining member so configured as to clasp and hold coil springs inserted in the axial direction, and one of the spring restraining members is a closed spring restraining member that receives the tip of a coil spring when the coil spring is rotated in the circumferential direction after having been inserted in the open type spring restraining members.
1. A spring restraining clip for mounting the axial terminus of a coil spring on a vehicle chassis via a spring seat, comprising:
three circumferentially-spaced spring restraining members disposed on one side of the spring restraining clip; wherein
two of the spring restraining members are open-type spring restraining members, such that they are configured to clasp and hold the coil spring when the coil spring is inserted into the open-type spring restraining members in an axial direction along a longitudinal axis of the coil spring;
one of the spring restraining members is a closed-type spring restraining member, such that it is configured to receive and axially retain a tip of the coil spring when the coil spring is rotated in a circumferential direction after the coil spring is inserted in the open-type spring restraining members;
the coil spring defines a circumferential travel path when it is rotated in said circumferential direction;
the closed-type spring restraining member defines a loop structure covered by a bridge;
the circumferential travel path lies under the bridge;
the closed-type spring restraining member further includes a spring tab that extends obliquely downwardly from the bridge in the direction of travel of the coil spring; and wherein
the spring tab is so structured as to contact the coil spring to apply thrust force to the coil spring.
2. The spring restraining clip of claim 1 , wherein:
the open-type of spring restraining members each includes a spring retaining pawl to arrest looseness of an inserted coil spring, and further includes ribs to prevent the spring retaining pawl from turning up during spring insertion.
3. The spring restraining clip of claim 2 , wherein three circumferentially-spaced spring seat locking pawls for attaching the spring seat are disposed on the side of the spring restraining clip opposite the side on which are disposed the spring restraining members.
4. The spring restraining clip of claim 3 , wherein the spring seat locking pawls are so configured as to have different structures.
5. The spring restraining clip of claim 4 , wherein the spring seat locking pawls include respective portions extending radially inwardly so as to compensate for deformation of the spring seat locking pawls due to spring load.
6. The spring restraining clip of claim 5 , wherein the spring restraining members are disposed on the spring restraining clip so as not to be diametrically opposed to one another.
7. The spring restraining clip of claim 1 , wherein movement of the coil spring in the direction of travel is facilitated, while movement in the opposite direction is impeded.
