Anchor bolt providing for fall protection
View Patent ↗An anchor bolt providing for fall protection. The anchor bolt has an anchoring device that may be of any standard type, for making use of an aperture either in or through a structure as an anchoring point, an elongate flexible member connected to the anchoring device at one end of the elongate flexible member, and a handle connected to a second end of the flexible member. The handle member is pivotally attached to the second end, for pivoting about the elongate axis of the flexible member as it extends from the second end. Preferably, the anchoring device is a novel, toggling type in which a toggling member is pivotally attached to the flexible member at a ball joint.
1. An anchor bolt for temporarily attaching to a structure having an anchoring aperture therein or therethrough, to provide fall protection to a user, the anchor bolt comprising:
an elongate flexible member defining, along its length, an elongate axis, and having first and second ends;
an anchoring device connected to said flexible member at said first end, said anchoring device being adapted so that, by use of manual manipulation that is either direct or remote, the user can cause said anchoring device to adopt at least two different configurations or orientations, a relatively contracted or narrow configuration or orientation in which said anchoring device is effectively dimensionally suitable for manual insertion into or through the aperture, and a relatively expanded or bluff configuration or orientation in which said anchoring device is effectively dimensionally unsuitable for removal from or through the aperture without substantial resistance; and
a handle member pivotally attached to said second end, for pivoting about the elongate axis as it extends from said second end.
2. The anchor bolt of claim 1 , wherein said anchoring device is of the expansion type, comprising at least two wedging members that slide relative to one another to cause an effective dimensional expansion or contraction of the anchoring device in a direction that is substantially perpendicular to the elongate axis as it extends from said first end.
3. The anchor bolt of claim 1 , wherein said anchoring device is of the toggling type, comprising an elongate toggling member that is pivotally attached to said flexible member.
4. The anchor bolt of claim 3 , wherein said toggling member is pivotally attached to said flexible member at a ball joint.
5. The anchor bolt of claim 4 , wherein said toggling member is elongate and has a maximum dimension in a direction perpendicular to its elongate axis, wherein said maximum dimension defines a diameter of a cylindrical surface of said toggling member.
6. A toggle bolt for temporarily attaching to a structure having an aperture therethrough, to provide for fall protection, comprising:
an elongate flexible member defining, along its length, an elongate axis and having an end; and
an anchoring device connected to said flexible member at said end, said anchoring device being adapted so that, by use of manual manipulation that is either direct or remote, the user can cause said anchoring device to adopt at least two different configurations or orientations, a relatively contracted or narrow configuration or orientation in which said anchoring device is effectively dimensionally suitable for manual insertion into or through the aperture, and a relatively expanded or bluff configuration or orientation in which said anchoring device is effectively dimensionally unsuitable for removal from or through the aperture without substantial resistance, wherein said anchoring device includes a toggling member for adopting said orientations, said toggling member being pivotally attached to said cable at said end at a first ball joint so that said toggling member is permitted to pivot about the elongate axis and at least one axis perpendicular thereto.
7. The toggle bolt of claim 6 , wherein said toggling member is elongate and has a maximum dimension in a direction perpendicular to its elongate axis, wherein said maximum dimension defines a diameter of a cylindrical surface of said toggling member.
8. The toggle bolt of claim 7 , wherein said relatively expanded or bluff configuration or orientation corresponds to a locking position of said toggling member, and wherein said toggling member has a substantially planar surface that is substantially perpendicular to the elongate axis of said toggling member when said toggling member is in said locking position.
9. The toggle bolt of claim 8 , wherein the aperture is a round hole, further comprising a hole plug slidably disposed about said flexible member, said hole plug having a substantially cylindrical hole plugging portion.
10. The toggle bolt of claim 9 , further comprising a spring for biasing said hole plug toward said toggling member.
11. The toggle bolt of claim 10 , further comprising an elongate control member pivotally attached to said toggling member and extending through said hole plug to provide for remotely pivoting said toggling member.
12. The toggle bolt of claim 11 , wherein said control member is pivotally attached to said toggling member at a second ball joint.
13. The toggle bolt of claim 9 , further comprising an elongate control member pivotally attached to said toggling member and extending through said hole plug to provide for remotely pivoting said toggling member.
14. The toggle bolt of claim 13 , wherein said control member is pivotally attached to said toggling member at a second ball joint.
15. The toggle bolt of claim 6 , wherein the aperture is a round hole, further comprising a hole plug slidably disposed about said flexible member, said hole plug having a substantially cylindrical hole plugging portion.
16. The toggle bolt of claim 15 , further comprising a spring for biasing said hole plug toward said toggling member.
17. The toggle bolt of claim 16 , further comprising an elongate control member pivotally attached to said toggling member and extending through said hole plug to provide for remotely pivoting said toggling member.
18. The toggle bolt of claim 17 , wherein said control member is pivotally attached to said toggling member at a second ball joint.
19. The toggle bolt of claim 15 , further comprising an elongate control member pivotally attached to said toggling member and extending through said hole plug to provide for remotely pivoting said toggling member.
20. The toggle bolt of claim 19 , wherein said control member is pivotally attached to said toggling member at a second ball joint.
21. The toggle bolt of claim 6 , further comprising an elongate control member pivotally attached to said toggling member for remotely pivoting said toggling member.
