Abstract

A bracket for mounting electrical boxes to channel-shaped metal wall studs having open and closed sides. The bracket has opposed stud gripping elements that enable the bracket to be mounted to studs of different sizes, and to either the open or closed side of the stud.

Claims

1. A bracket for mounting electrical boxes to wall studs, said bracket including a web having a pair of first and second opposed flanges extending therefrom and between which a wall stud is receivable, said first flange being substantially longer than said second flange and having a free end portion remote from said web, an elongated resilient arm extending from said free end portion of said first flange back toward said web in inwardly inclined spaced relationship to said first flange, said arm being substantially longer than said second flange and having an arm terminal end portion adjacent said web, and stud gripping means on said arm terminal end portion and on said second flange for gripping a stud therebetween.

2. The bracket of claim 1 wherein said stud gripping means on said arm terminal end portion comprises a plurality of spaced-apart barbs.

3. The bracket of claim 2 wherein said barbs are spaced-apart transversely of said arm.

4. The bracket of claim 2 wherein said barbs are spaced-apart longitudinally of said arm.

5. The bracket of claim 1 wherein said resilient arm is integral with said first flange.

6. The bracket of claim 1 wherein said resilient arm is inwardly inclined with respect to said first flange at an included angle of about 15-25 degrees.

7. The bracket of claim 1 wherein said first flange comprises a box attaching flange and has box attaching means thereon.

8. The bracket of claim 1 wherein said web has a web length between oppposite web ends and said arm has an arm width substantially less than said web length.

9. The bracket of claim 1 wherein said stud gripping means on said second flange comprises a plurality of spaced-apart barbs.

10. The bracket of claim 9 wherein said barbs are spaced-apart transversely of said second flange.

11. The bracket of claim 9 wherein said barbs are spaced-apart longitudinally of said second flange.

12. The bracket of claim 1 wherein said second flange has opposite side edges and a terminal end, extensions extending outwardly from said side edges adjacent said terminal end, and said gripping means on said second flange being on said extensions.

13. The bracket of claim 12 wherein said gripping means comprises a plurality of barbs on each of said extensions spaced-apart longitudinally of said second flange.

14. The bracket of claim 13 wherein said extensions are bent inwardly of said second flange.

15. The bracket of claim 14 wherein at least one of said barbs on each of said extensions is deformed inwardly of its extension.

16. The bracket of claim 1 wherein said second flange has opposite side edges and said stud gripping means on said second flange includes a plurality of transversely spaced-apart barbs located both outwardly and inwardly of said side edges.

17. A bracket for mounting electrical boxes to wall studs, said bracket including a web having a pair of spaced-apart opposed first and second flanges extending therefrom for receiving a wall stud therebetween, said flanges having stud gripping means thereon for gripping a stud therebetween, said second flange having opposite side edges and a terminal end, extensions connected with said side edges of said second flange adjacent said terminal end thereof, said extensions projecting outwardly from said side edges and back toward said web in outwardly-spaced relationship to said side edges, said extensions being bent inwardly of said second flange toward said first flange about bend lines extending along said side edges, and said stud gripping means on said second flange including a plurality of barbs on each said extension spaced-apart longitudinally of said second flange.

18. The bracket of claim 17 including extensions extending outwardly from said side edges adjacent said terminal end, said barbs being on said extensions.

19. The bracket of claim 18 wherein said extensions are bent inwardly of said second flange.

20. The bracket of claim 19 wherein at least one said barb on each said extension is deformed inwardly of its extension.

21. A bracket for mounting electrical boxes to wall studs, said bracket including a web having a pair of spaced-apart opposed first and second flanges extending therefrom for receiving a wall stud therebetween, stud gripping means on said flanges and extending inwardly thereof for gripping a stud therebetween, said stud gripping means on each of said flanges including a plurality of barbs spaced-apart both longitudinally and transversely thereof.

22. The bracket of claim 21 wherein said first flange has an elongated resilient arm connected therewith remote from said web and extending generally along said first flange in inwardly inclined relationship thereto back toward said web, said arm having an arm terminal end portion located adjacent said web, and said barbs on said first flange being on said arm terminal end portion.

23. The bracket of claim 21 wherein said web has a web length between opposite web ends, said web having a narrow web extension portion having a length substantially less than said web length, and said second flange being on said web extension portion.

24. The bracket of claim 23 wherein said web has a web width and said web extension portion has a width substantially less than said web width.

25. The bracket of claim 24 wherein said web extension portion is substantially centrally located between said web ends.

26. A bracket for mounting electrical boxes to wall studs, said bracket including a web having a pair of first and second opposed flanges extending therefrom and between which a wall stud is receivable, said first flange having a free end portion remote from said web, a resilient arm extending from said free end portion of said first flange back toward said web in inwardly inclined spaced relationship to said first flange, said arm having an arm terminal end portion adjacent said web, and stud gripping means on said arm terminal end portion and on said second flange for gripping a stud therebetween, and said stud gripping means on said arm terminal end portion comprising a plurality of barbs spaced-apart both longitudinally and transversely of said arm.

27. A bracket for mounting electrical boxes to wall studs, said bracket including a web having a pair of first and second opposed flanges extending therefrom and between which a wall stud is receivable, said first flange having a free end portion remote from said web, a resilient arm extending from said free end portion of said first flange back toward said web in inwardly inclined spaced relationship to said first flange, said arm having an arm terminal end portion adjacent said web, stud griping means on said arm terminal end portion and on said second flange for gripping a stud therebetween, and said stud gripping means on said second flange comprising a plurality of barbs spaced-apart both longitudinally and transversely of said second flange.

28. A bracket for mounting electrical boxes to wall studs, said bracket including a web having a pair of first and second opposed flanges extending therefrom and between which a wall stud is receivable, said first flange having a free end portion remote from said web, a resilient arm extending from said free end portion of said first flange back toward said web in inwardly inclined spaced relationship to said first flange, said arm having an arm terminal end portion adjacent said web, and stud gripping means on said arm terminal end portion and on said second flange for gripping a stud therebetween, said second flange having opposite side edges and a terminal end, extensions extending outwardly from said side edges adjacent said terminal end, said stud gripping means on said second flange being on said extensions and comprising a plurality of barbs on each of said extensions spaced-apart longitudinally of said second flange, said plurality of barbs on each said extension including an initial barb located closest to said web and a terminal barb located closest to said terminal end of said second flange, and said terminal barbs extending inwardly of said second flange a greater distance than said initial barbs.
