Abstract

Disclosed is a molded plastic fastener for plate like members which is formed of synthetic resin having a suitable resiliency. The fastener is formed with a first portion including a groove through which an edge portion of a plate like member is inserted and within which the member is resiliently held and a positioning member for preventing the member from moving in the groove and a second portion including an anchor leg for anchoring the device to a support structure.

Claims

1. A one-piece plastic fastener for insulatingly fixing a plate-like member to a support structure comprising a body formed with a groove extending length-wise along one surface of said body and adapted to hold the plate-like member therein, at least one cavity extending longitudinally in said body and disposed parallel to but spaced from said groove to form a dielectric resilient wall between the cavity and the groove, at least one spring member disposed within said cavity and acting against the resilient wall adjacent to said groove to provide a resilient bias against the plate-like member when positioned in said groove, anchoring means extending perpendicular from said body for securing same to the support structure, a resilient integral arm extending longitudinally away from one end of said body having means for contacting and positioning the member held in said groove in a retained fashion.

2. A molded plastic fastener as set forth in claim 6, wherein the contact means on said arm is formed at the free end thereof and includes a cam surface terminating in a shoulder facing said body for catching an edge of the plate-like member.

3. A molded plastic fastener as set forth in claim 1, the contact means on said arm is formed in the vicinity of the free end thereof with a protrusion which is adapted to enter a hole provided in the plate like member.

4. A one-piece plastic fastener as set forth in claim 1 wherein at least one wall forming said cavity is provided with a detent means and said spring means is provided with means for cooperating with said detent to prevent withdrawal of said spring from within said cavity.

5. A one-piece plastic fastener of the type set forth in claim 4 wherein said body is provided with two cavities located on opposite sides of said groove and a spring means in each cavity acting in a direction in opposition to the other spring means to thereby pinch said plate-like member when disposed is said groove.

6. A one-piece plastic fastener as set forth in claim 5 wherein said cavities are generally rectangular in shape and said spring members are flat, bowed sheet material having their convex sides in opposition and in contact with the resilient walls of said cavities adjacent said groove and having their ends in contact with the opposite walls of the respective cavities in said body.
