Abstract
A fastener device is disclosed for fastening a member having a post extending therefrom to a retainer defining an aperture. The arrangement is such that the post is received within the aperture of the retainer for lockably retaining the member relative to the retainer. The device includes a washer which has a peripheral rim and a first and a second face. The washer defines a hole for the reception therein of the post. The washer has a plurality of barbs which surround the hole, the barbs lockably cooperating with the post when the post is inserted into the hole. Also, the washer defines a plurality of ears which extend from the peripheral rim such that when the post is inserted into the aperture of the retainer, the ears engage the retainer for retaining the member relative to the retainer.

A fastener device for fastening a member having a post extending therefrom to a retainer defining an aperture, said device comprising:
- a washer having a peripheral rim and a first and a second face, said washer including a hole for the reception therein of the post, said hole being originally smaller than an outer diameter of the post, said washer further including a plurality of barbs which surround said hole, said barbs being configured to cooperate with the post when the post is inserted into said hole of said washer so as to secure said washer to the post, said barbs being adapted to allow said hole to increase in size to receive the post as the post is pushed through said hole, and said washer further including a plurality of ears extending from said peripheral rim such that when the post is inserted into the aperture of the retainer, said ears engage an inner surface of the retainer for securing the member and the retainer relative to each other, wherein each ear of said plurality of ears includes a first edge having a first and a second termination, said first edge being a portion of said rim, a first and second radial edge extending respectively from said first and said second termination, and an outer edge extending from said first radial edge to said second radial edge.
A fastener assembly comprising:
- a member having a post extending therefrom;
- a retainer defining an aperture for receiving therein said post, said retainer including an inner surface;
- and
- a washer having a peripheral rim and a first and a second face, said washer defining a hole for the reception therein of said post, said washer defining a plurality of barbs which surround said hole, said hole being at least partially defined by said barbs and a scalloped surface, said barbs and said scalloped surface cooperating with said post when said post is inserted into said hole so as to secure said washer to said post, and said washer further defining a plurality of ears extending from said peripheral rim such that when said post is inserted into said aperture of said retainer, said ears engage said inner surface of said retainer for securing said member and said retainer relative to each other.
A fastener device for securing a headlamp assembly, said fastener device comprising:
- a member secured to the headlamp assembly, said member having a post extending therefrom;
- a retainer defining an aperture for receiving therein said post, and
- a washer having a peripheral rim and a first and a second face, said washer defining a hole for the reception therein of said post, said washer defining a plurality of barbs which surround said hole, said barbs cooperating with said post when said post is inserted into said hole so as to secure said washer to said post, and said washer further defining a plurality of ears extending from said peripheral rim such that when said post is inserted into said aperture of said retainer, said ears engage said retainer for securing said member and said retainer relative to each other.
A fastener device for fastening a member having a post extending therefrom to a retainer defining an aperture, said device comprising:
- a washer having a peripheral rim and a first and a second face, said washer including a hole for the reception therein of the post, said washer further including a plurality of barbs which surround said hole, each barb of said plurality of barbs being of a generally triangular shaped configuration, said barbs being configured to cooperate with the post when the post is inserted into said bole of said washer so as to secure said washer to the post, and said washer further including a plurality of ears extending from said peripheral rim such that when the post is inserted into the aperture of the retainer, said ears engage an inner surface of the retainer for securing the member and the retainer relative to each other.
