Abstract

A masonry anchor comprising an anchor member having a socket formed in one end, the socket being configured to receive and secure a mounting portion of a mounting fastener.

First claim

The invention claimed is:

1. A masonry anchor comprising: an anchor member having a socket formed in one end, the socket being configured to receive a mounting portion of a mounting fastener, the anchor member including (a) a locking element and (b) a resilient band that extends around the locking element and that is formed separately from the locking element, the locking element configured to be urged radially outwardly by the mounting fastener when the mounting fastener is in a partially installed position in the socket, and the locking element configured to move radially inwardly into a groove defined by the mounting portion when the mounting fastener is in a fully installed position in the socket.

2. The masonry anchor of claim 1 , wherein the locking element is radially movable between a first position and a second position.

3. The masonry anchor of claim 2 , wherein the locking element is at least partially located within a void defined by the anchor member when the locking element is in the first position.

4. The masonry anchor of claim 3 , wherein the locking element is sized and shaped to be at least partially received in the groove defined by the mounting portion of the mounting fastener.

5. The masonry anchor of claim 4 , wherein the locking element is biased to the first position by the resilient band.

6. The masonry anchor of claim 4 , wherein a portion of the socket is shaped to receive a noncircular profile of the mounting portion of the mounting fastener to enable transmission of torque from the mounting fastener to the anchor member.

7. The masonry anchor of claim 6 , wherein the locking element is positioned relative to the portion of the socket such that the locking element is at least partially received in the groove when the noncircular profile of the mounting portion of the mounting fastener is received in the portion of the socket.

8. The masonry anchor of claim 6 , wherein the noncircular profile is rectangular.

9. The masonry anchor of claim 1 , wherein the socket is configured to receive the mounting portion of the mounting fastener via axial and rotational movement of the mounting portion relative to the socket.

10. The masonry anchor of claim 1 , wherein the resilient band includes a longitudinal split.

11. The masonry anchor of claim 1 , wherein the resilient band is configured to cause the locking element to move radially inwardly when the mounting fastener is in a fully installed position in the socket.

12. A kit comprising:
a mounting fastener having a mounting portion; and
a masonry anchor comprising an anchor member having a socket formed in one end, the socket being configured to receive the mounting portion of the mounting fastener, the anchor member including (a) a locking element and (b) a resilient band that extends around the locking element and that is formed separately from the locking element, the locking element configured to be urged radially outwardly by the mounting fastener when the mounting fastener is in a partially installed position in the socket, and the locking element configured to move radially inwardly into a groove defined by the mounting portion when the mounting fastener is in a fully installed position in the socket.

13. The kit of claim 12 , wherein the locking element is radially movable between a first position and a second position, the locking element sized and shaped to be at least partially received in the groove when in the first position to secure the mounting portion of the mounting fastener.

14. The kit of claim 12 , wherein the mounting fastener is one selected from the group consisting of: a screw thread, a hook, a bar, a clip, a low profile mount, a structural mount, and an eyelet.

15. A masonry anchor comprising: an anchor member having a socket formed in one end, the socket being configured to receive a mounting portion of a mounting fastener, the anchor member including (a) a locking element and (b) a resilient band that extends around the locking element and that includes a longitudinal split, the locking element configured to be urged radially outwardly by the mounting fastener when the mounting fastener is in a partially installed position in the socket, and the locking element configured to move radially inwardly into a groove defined by the mounting portion when the mounting fastener is in a fully installed position in the socket.

16. A kit comprising:
a mounting fastener having a mounting portion; and
a masonry anchor comprising an anchor member having a socket formed in one end, the socket being configured to receive the mounting portion of the mounting fastener, the anchor member including (a) a locking element and (b) a resilient band that extends around the locking element and that includes a longitudinal split, the locking element configured to be urged radially outwardly by the mounting fastener when the mounting fastener is in a partially installed position in the socket, and the locking element configured to move radially inwardly into a groove defined by the mounting portion when the mounting fastener is in a fully installed position in the socket.

17. The kit of claim 16 , wherein the mounting fastener is one selected from the group consisting of: a screw thread, a hook, a bar, a clip, a low profile mount, a structural mount, and an eyelet.
