[0097] It should be understood that the drawings are not necessarily to scale.

DETAILED DESCRIPTION

[0098] FIGS. 1-5 show the adjustable junction box system 2 of one embodiment of the present invention that employs a captured worm screw 6. Rotation of the worm screw 6 inclemently moves a junction box 10 into a wall (along the direction of Arrow A) or out of the wall (along Arrow B). The junction box 10 is of a configuration similar to traditional boxes that receive an electrical device, in this example an outlet 14. Those of ordinary skill in the art will appreciate, however, that the junction box 14 may be of any size and shape and may be designed to accommodate multiple electrical devices. The junction box 10 has a channel 18 that maintains the worm screw 6.

[0099] In operation, the junction box 10 is interconnected to a bracket 22 having a retainer 26 at an upper end 30 and a ledge 34 at a lower end 38. The retainer 26 receives an upper tab 42 extending from an upper surface 70 of the junction box 10, and the ledge 35 receives a complementary tab (not shown) extending from a lower surface of the junction box 10. The interface between the tabs and the retainer/ledge allows the junction box to move into and out the wall, but prevents movement of the junction box along the length of the stud. The bracket 22 also includes a series of openings 46 that selectively engage threads 50 of the worm screw 6. In operation, rotation of the captured worm screw 6 incrementally moves the interconnected junction box 10 into and out of the wall.

[0100] Anchor points 24 on the bracket 22 are adapted to receive screws or nails for interconnection to a stud. One of ordinary skill in the art will appreciate that at least one of these anchor points 24 may be a slot or an arcuate slot that allows for selective rotation of the bracket to address angular (i.e., non-plumb) stud irregularities.

[0101] The junction box 10 selectively receives a cover 54 with upper and lower arms 58. The arms end 58 in upper and lower fingers 62 that are selectively received within openings 66 in the upper surface 70 and the lower surface 74 of the junction box 10. Apertures 78 are provided in a front face 82 of the cover 54 that allows selective access to an end of the worm screw 6, which allows a technician to rotate the worm screw 6. Apertures 78 may be provided on both sides of the cover 54 such that cover orientation relative to the junction box 10 is irrelevant. Passages 86 are provided within the cover that allow a technician to insert a tool, such as a flathead screwdriver, into a closed junction box 10 to selectively deflect the fingers 62 from the openings and remove the cover 54 from the junction box 10.

[0102] FIGS. 6 and 7 show another embodiment of an adjustable junction box system 202 that employs a junction box 210 that selectively interfaces with a bracket 222. As in the embodiments described above, the junction box 210 in this embodiment includes an upper tab and a lower tab (not shown) that selectively engage a retainer 226 and ledge 234, respectively, provided in the bracket 222. The primary difference to that a selectively deflectable clip 207 is provided instead of a worm screw.

[0103] More specifically, the clip 207 is interconnected on a first end 209 to an inner surface 213 of the junction box 210. One of ordinary skill in the art will also appreciate that the first end 209 can be interconnected to the outer surface of the junction box. A second end 217 of the clip 207 extends through a slot 218 in the outer surface of the junction box and is designed to flex to be received by one of the openings 246 in the bracket 222. A small opening or groove 221 in the clip 207 may be provided, wherein an aperture 278 in a selectively-interconnectable cover 254 allows for insertion of a tool to flex the second end 217 of the clip 207 to remove it from the bracket opening 246, which allows the junction box 210 to incrementally slide into or out of the wall. The cover of this embodiment of the present invention is very similar to that described above wherein arms 258 are provided that end in fingers 262 that are selectively received in openings 266 in the upper surface 270 and lower surface 274 of the junction box 210.

[0104] FIGS. 8 and 9 show another embodiment of the present invention that uses a cover 354 having plurality standoffs 306 that selectively interconnect to nut plates 309 integrated into a rear surface of the junction box 310. The cover 354 also is adapted to receive and secure an outlet or switch.

[0105] FIGS. 10 and 11 show yet another embodiment of the present invention where the cover 454 employs arms 458 that extends from the back surface. The arms 458 employ a plurality of teeth 406 that selectively engage protrusions 409 provided in the upper and lower surfaces of the junction box 410. The arms 458 are flexed outwardly to remove the teeth 406 from the protrusion 409 which allows for selective adjustment or removal of the cover 454. That is, the cover and interconnected electrical device can be spaced as needed to accommodate interior surface installation.

[0106] FIGS. 12 and 13 show another embodiment of the present invention comprised of a junction box housing 506 that receives a junction box 510. The junction box housing 506 is interconnected to a wall stud and the junction box 510 is selectively received within the junction box housing 506. Here, an adjustment wheel 509 is provided that when rotated in one direction moves the junction box 510 into the junction box housing 506. Rotation of the adjustment wheel 509 in the opposite direction will urge the junction box 510 and interconnected outlet from the wall.

[0107] FIGS. 14 and 15 show another embodiment of the present invention that uses an adjustable collar 606 interconnected to a junction box housing 609 by a plurality of adjustable screws 611. The junction box housing 609 is interconnected to a stud. Movement of the adjustment screws 611 will selectively move the collar 606 into and out of the junction box housing 609. The collar 606 is also configured to selectively receive a cover 654 that accommodates an outlet 614. The cover may include arms 658 ending in fingers 662 that are received in openings in the adjustable collar 606.

[0108] While various embodiments of the present invention have been described in detail, it is apparent that modifications and alterations of those embodiments will occur to those skilled in the art. It is to be expressly understood that such modifications and alterations are within the scope and spirit of the present invention, as set forth in the following claims. Further, it is to be understood that the invention(s) described herein is not limited in its application to the details of construction and the arrangement of components set forth in the preceding description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of including, comprising, or having and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.
