PUSH-ON MECHANICAL FASTENER FOR LIGHTING FIXTURE

1 . A push-on fastener comprising:

a base plate having an opening formed therein for receiving a threaded pipe;

at least one pair of tangs formed in the base plate, the tangs formed on opposing sides of the opening; and

an internal edge defining a portion of each tang extending into the opening such that the distance between the internal edge of two opposing tangs is less than the diameter of the opening.

2 . The push-on fastener of claim 1 , further comprising a plurality of slots forming the boundaries of each tang.

3 . The push-on fastener of claim 1 , wherein the base plate forms a portion of a troffer.

4 . The push-on fastener of claim 1 , further comprising one or more holes for attaching the base plate to a troffer.

5 . The push-on fastener of claim 1 , further comprising multiple pairs of tangs.

6 . The push-on fastener of claim 1 , wherein the base plate has a dual-tear drop shape.

7 . The push-on fastener of claim 1 , wherein upon insertion of a threaded pipe through the hole the internal edges of each tang engage the threaded pipe causing the tangs deflect along the threaded pipe permitting the tangs to pass over threaded pipe and upon cessation of a force required for insertion the tangs spring back to their un-deflected position and secure the base material to the threaded pipe.

8 . A lighting fixture comprising:

a troffer having a hole formed therein for receiving a threaded pipe; and

a push-on fastener having an opening and at least one pair of tangs, the opening sized to receive a threaded pipe, the at least one pair of tangs formed on opposing sides of the opening, and each tang of the at least one pair of tangs defined by an internal edge extending into the opening such that the distance between the internal edges is less than the diameter of the opening.
