Abstract

Abstract A non-nail U-shaped clamp type barbed bracket for connecting electric outlet box to a wall stud in which the U-shaped clamp is permanently secured to one side wall of the outlet box and the clamp can be hammered into place at a desired position on a wall stud. The two sides of the U-shaped clamp will frictionally grip the adjacent sides of the stud and each clamp side has inwardly extending barbs which will dig into the stud and prevent the removal of the clamp therefrom. In addition, the web portion of the clamp has an inwardly extending pointed prong that will enter the stud and prevent any vertical movement of the clamp and outlet box with respect to the stud.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 253 words
A bracket permanently secured to a wall of an electric outlet box, the front edges of the box lying in the same flat plane; (a) said bracket having a web portion extending from the box wall with the plane of the web paralleling the flat plane of the box front edges and being spaced rearwardly therefrom a distance sufficient to accommodate the thickness of the wallboard associated with the box; (b) said web having a prong extending rearwardly therefrom and forming a right angle with the plane of the web so that when the bracket is hammered into place on a stud, the prong will enter the stud and prevent any vertical movement of the bracket and box; (c) said bracket having an intergral side wall extending rearwardly and substantially at right angles to the plane of the web so that when the bracket is hammered into place on the stud, the bracket side wall will contact the adjacent side of the stud; and (d) said bracket side wall having an inwardly inclined barb extending toward the web so that the barb will engage with the stud wall and prevent the removal of the bracket and box from the stud; and (e) whereby the bracket and box can be secured to a stud without the use of any nails and the prong and the barb will prevent a vertical or horizontal movement of the bracket and box with respect to the stud after once the bracket is hammered into place on the stud.
