Abstract

An attachment can secure an electrical box to a support structure without the use of fasteners. An attachment body can be configured to be secured to the support structure. One or more engagement arrangements can include first and second arms that are configured to engage first and second mounting openings of an electrical box without use of a separate fastener.

First claim

The invention claimed is:

1. An attachment for securing an electrical box to a support structure, the electrical box including a back side with a first mounting opening and a second mounting opening, the attachment comprising:
an attachment body configured to be secured to the support structure; and
one or more engagement arrangements that are integrally formed with the attachment body and include:
a first arm having a first section and a second section that are joined by a bend; and
a second arm having a hook;

the one or more engagement arrangements being configured to secure the electrical box to the attachment body, without use of a separate fastener, with:
the attachment body being configured to be disposed along the back side of the electrical box;
the first and second sections of the first arm being configured to extend from the back side of the electrical box through and within the first mounting opening into an interior of the electrical box, the first section and the second section of the first arm each configured to be in contact with an edge of the first mounting opening;
the hook configured to extend from the back side of the electrical box through the second mounting opening into the interior of the electrical box; and
the bend biasing at least one of the first or second sections of the first arm to secure the first arm within the first mounting opening,

the bend is configured to be disposed inside of the electrical box when the first and second sections of the first arm extend through the first mounting opening, and
the bend includes a U-shaped bend between the first and second sections of the first arm.

2. The attachment of claim 1 , wherein the hook is configured to elastically engage an inside wall of the electrical box to secure the second arm within the second mounting opening.

3. The attachment of claim 1 , wherein, with the electrical box attached to the attachment, the attachment body is configured to be arranged in a locked configuration in which the attachment body secures the attachment and the electrical box against sliding along the support structure, and an unlocked configuration in which the attachment body allows the attachment and the electrical box to be slid along the support structure.

4. The attachment of claim 1 , wherein the first arm further includes a first tab that is configured to engage an inside wall of the electrical box to secure the first arm within the first mounting opening.

5. The attachment of claim 4 , wherein the first tab extends from the first section of the first arm away from the second section of the first arm.

6. The attachment of claim 4 , wherein the first arm further includes a second tab, opposite the bend, that is configured to engage the back side of the electrical box when the first arm is secured within the first mounting opening.

7. The attachment of claim 1 , wherein the attachment is configured to surround the support structure to secure the attachment to the support structure.

8. The attachment of claim 7 , with the support structure including a channel with a first internal lip and a second internal lip that is opposite the channel from the first internal lip, the attachment further comprising:
at least one flexible arm that is configured to engage the first internal lip and the second internal lip of the support structure to secure the attachment relative to the support structure.

9. An attachment for securing an electrical box to a between-stud support structure that has a front side and a back side, the electrical box including a back side with a first mounting opening and a second mounting opening, the attachment comprising:
an attachment body configured to be secured to surround the between-stud support structure with the attachment body configured to be in contact with the between-stud support structure and the electrical box and disposed between the front side of the between-stud support structure and the back side of the electrical box; and
a locking tab and a void configured to receive the locking tab to secure the attachment body around the between-stud support structure;
one or more engagement arrangements that include:
a first arm that includes a first protrusion and is configured to extend from the attachment body along the back side of the electrical box; and
a second arm that includes a second protrusion and is configured to extend from the attachment body along the back side of the electrical box, opposite the attachment body from the first arm;

the first and second protrusions being configured to be inserted from the back side of the electrical box through the first and second mounting openings, respectively, to secure the electrical box to the attachment body without use of a separate fastener, the first protrusion configured to be in contact with the electrical box at the first mounting opening when the attachment is secured to the electrical box, and the second protrusion configured to be in contact with the electrical box at the second mounting opening when the attachment is secured to the electrical box.

10. The attachment of claim 9 , wherein the first protrusion includes a U-shaped bend that is configured to extend into an inside of the electrical box to secure the attachment to the electrical box; and
wherein the second protrusion includes a hook that is configured to extend into the inside of the electrical box to secure the attachment to the electrical box.

11. The attachment of claim 9 , wherein the first protrusion includes:
a first tab that is configured to engage an inside wall of the electrical box when the first protrusion is inserted through the first mounting opening; and
a second tab that is configured to engage the back side of the electrical box when the first protrusion is inserted through the first mounting opening.

12. A securing system comprising:
an electrical box that has a first mounting opening and a second mounting opening; and
an attachment for securing the electrical box to a support structure, the attachment comprising:
an attachment body configured to be secured to the support structure; and
one or more engagement arrangements that are integrally formed with the attachment body and include a first arm having a first section and a second section that are joined by a bend, and a second arm having a hook;
the one or more engagement arrangements being configured to secure the electrical box to the attachment body, without use of a separate fastener, the attachment being installed with the electrical box with:
the attachment body disposed along a back side of the electrical box;
the first and second sections of the first arm extending from the back side of the electrical box within the first mounting opening and into an interior of the electrical box;
the hook extending from the back side of the electrical box through the second mounting opening into the interior of the electrical box; and
the bend biasing at least one of the first or second sections of the first arm to secure the first arm within the first mounting opening.

13. The securing system of claim 12 , wherein the first and second arms extend from opposite sides of the attachment body, and
wherein the first arm has a U-shaped bend at a free end of the first arm that is configured to extend into the interior of the electrical box to secure the attachment to the electrical box.

14. An attachment for securing an electrical box to a support structure, the electrical box including a back side with a first mounting opening and a second mounting opening, the attachment comprising:
an attachment body configured to be secured to t
