Description of a Preferred Embodiment
Illustrated in FIG. 1 is an apparatus embodying the invention and for use in positioning an electrical outlet or switch box 10 against a vertical stud 12 in the proper orientation such that the outlet box can be secured by nails 14 to the side 16 of the vertical stud and such that the outlet box 10 is in the desired vertical position and is positioned forwardly with respect to the stud 12 at a proper forward spacing with respect to the vertical forward face 18 of the stud.
The apparatus embodying the invention includes a base or a base plate 20 adapted to be positioned against the forward face 18 of the stud 12, the base including a channel portion defined by a planar rear wall 22 and a pair of spaced apart sidewalls 24 extending forwardly from the sides of the rear wall 22. The base 20 also includes a pair of flanges or ears 26 projecting outwardly from the forward portions of the sidewalls 24, each of the flanges 26 being planar and having rearward planar surfaces 28 perpendicular to the sidewalls 24 of the base. The planar rear wall 22 has a planar rearward surface adapted to engage the forward face 18 of the stud 12 and has a width approximately equal to the width of the stud. The flanges 26 are spaced forwardly from the rear wall 22 by a distance approximately equal to the desired distance between the forward face of the stud 12 and the forward face of the outlet box 10 to be secured to the stud.
Means are also provided for securing outlet boxes to one or both of the sidewalls 24 of the base plate 20, and as to each outlet box, a portion of the face of the outlet box is positioned against the rearward surface 28 of one of the flanges 26 of the base. In the illustrated arrangement, the means for securing the outlet box 10 in place includes a pair of clamp members 30, one of the clamp members 30 being positioned on one side of the base and another of the clamp members being positioned on an opposite side of the base. Each of the clamp members 30 is pivotally joined to the base adjacent a forward portion of the sidewall 24 and is pivotally movable such that a rearward portion 32 of the clamp member is movable toward and away from the outside surface of the sidewall 24. More particularly, in the illustrated arrangement, each of the outwardly extending flanges 26 includes an elongated vertically extending slot 36 adapted to house a central portion of one of the clamp members 30 so as to pivotally support that clamp member. Means are also provided for resiliently biasing the ends 32 of the clamp members into clamping engagement with the sidewalls 24 of the base. In the illustrated arrangement, each clamp member 30 includes a forwardly projecting end 38, and a compression spring 40 is provided between the forward projecting ends 38 of the pair of clamp members 30 for forcing them outwardly away from one another.
Means are also provided for supporting the base 20 and the clamp members 30 for vertical adjustable movement with respect to the vertical stud 12 and such that the outlet box 10 is supported in the proper vertical position on the stud 12. The supporting means includes a central vertically extending sleeve or tube 44 fixed to a central portion of the planar rear wall 22 of the base 20 and having a vertical longitudinal axis. In one form of the invention, the sleeve 44 can be welded to the rear wall 22 equidistant the sidewalls 24 of the base. The sleeve 44 includes central bore 46 adapted to slideably house a linear vertically extending support pipe or tube 48 and such that the base 20 is slideably supported on the pipe or tube 48 for selective vertical movement. Detent means are also provided for releaseably supporting the base 20 on the tube 48 in a selected vertical position. In the illustrated arrangement, the detent means includes a spring or clip 50 surrounding a portion of the sleeve 44 and including a portion housed in a horizontal slot 52 cut in the sleeve 44. The vertical pipe 48 can include one or more complementary horizontal slots 54 cut into its surface and adapted to house the spring 50 when the base 20 is in the selected vertical position on the pipe 48. In operation, if the free end 58 of the spring 50 is pulled outwardly away from the pipe 48, the sleeve 44 and base 20 will be freely slideably movable on the vertical pipe 48.
Means are also provided for positioning the outlet box 10 vertically with respect to the base 20. This means includes a pair of tabs 60 extending outwardly from a lower portion of the rear wall 22 and being generally coplanar with the rear wall. The tabs 60 each include an upper surface 62 adapted to support the bottom of the outlet box 10 when the outlet box 10 is held in place by one of the clamp members 30.
In operation of the apparatus shown in the drawings, an outlet box or switch box 10 can be inserted between the end 32 of a clamp member 30 and the opposed sidewall 24 of the base 20 and with the bottom of the outlet box positioned on the upper edge 62 of one of the outwardly projecting tabs 60. The rear wall 22 of the base 22 is then positioned against the forward face 18 of the stud 12 and with a side 16 of the outlet box positioned against a side of the vertical stud. The nails 14 in the upper surface of the outlet box 10 can be driven into the stud 12 to secure the outlet box in place.
Various features of the invention are set forth in the following claims.
