Channel strut fasteners
Provided herein is a fastener that may be used to secure objects to a channel strut or attach a channel strut to a structure. In an arrangement, the fastener is a fastener block configured for disposition within the interior of a channel strut. The fastener block has a body that includes at least one pair of spaced apart and parallel recesses (e.g., recessed channels) sized to engage the inward lips of the strut channel. Once the pair to recessed channels engage the strut channel lips, the fastener block is prevented from rotating. At least one aperture extends through the fastener block between the parallel recessed channels. A fastener recess (e.g., hexagon recess) is recede into the block around the aperture. A standard nut or bolt may be inserted into the fastener recess.
1. A fastener for use in attaching objects to a strut channel, comprising:
a body having an upper surface and a lower surface;
a first aperture passing through the body between the upper surface and the lower surface;
a first fastener recess recessed in the upper surface of the body and around the first aperture;
a first pair of recessed channels recessed in the lower surface of the body, the first pair of recessed channels being parallel and disposed on opposing sides of the first aperture;
first and second side surfaces extending between the upper surface and the lower surface, the first and second side surfaces being generally parallel to the first pair of recessed channels wherein a sidewall distance between the first and second side surfaces defines a width of the fastener; and
at least first and second raised protrusions disposed on the first and second side surfaces, wherein a distance between outside surfaces of the protrusions is greater than the sidewall distance.
2. The fastener of claim 1 , wherein the fastener recess has a hexagonal shape.
3. The fastener of claim 1 , further comprising:
a second fastener recess recessed in the lower surface of the body and around the first aperture.
4. The fastener of claim 3 , wherein the first fastener recess and the second fastener recess have different cross-dimensions.
5. The fastener of claim 3 , further comprising:
a second pair of recessed channels recessed in the upper surface of the body, the second pair of recessed channels being parallel and disposed on opposing sides of the first aperture.
6. The fastener of claim 5 , wherein the first pair of recessed channels and the second pair of recessed channels are aligned.
7. The fastener of claim 3 , further comprising:
a second aperture passing through the body between the upper surface and the lower surface;
a third fastener recess recessed in the upper surface of the body and around the second aperture; and
a fourth fastener recess recessed in the lower surface of the body and around the second aperture.
8. The fastener of claim 7 , wherein the first fastener recess, the second fastener recess, the third fastener recess and the fourth fastener recesses each have different cross-dimensions.
9. The fastener of claim 7 , wherein a reference line passing through centers of the first and second apertures is parallel to the first pair of recessed channels.
10. The fastener of claim 1 , further comprising:
ridge extending from a sidewall surface of first fastener recess and extending into an interior of the first fastener recess, wherein the ridge defines a reduced cross-dimension location in the first fastener recess.
11. The fastener of claim 1 , wherein the protrusions are integrally formed with the body of the fastener.
12. The fastener of claim 1 , wherein the body is formed of a polymeric material.
13. The fastener of claim 1 , wherein at least one channel of the first pair of channels further comprises a partial web extending from a sidewall surface of the at least one channel, wherein the web is at least partially deflectable.
14. The fastener of claim 1 , wherein at least one channel of the first pair of channels further comprises first and second angles sidewalls, wherein the sidewall angle from a larger open end to a smaller closed end of the channel.
15. A fastener for use in attaching objects to a strut channel, comprising:
a body having an upper surface and a lower surface;
a first aperture passing through the body between the upper surface and the lower surface;
a first hexagonal fastener recess recessed in the upper surface of the body and around the first aperture;
a second hexagonal fastener recess recessed in the lower surface of the body and around the first aperture, wherein the first hexagonal fastener recess and the second hexagonal fastener recess have different cross-dimensions; and
a first pair of recessed channels recessed in the lower surface of the body, the first pair of recessed channels being parallel and disposed on opposing sides of the first aperture; and
a second pair of recessed channels recessed in the upper surface of the body, the second pair of recessed channels being parallel and disposed on opposing sides of the first aperture.
16. The fastener of claim 15 , further comprising:
a second aperture passing through the body between the upper surface and the lower surface;
a third hexagonal fastener recess formed at least partially below the upper surface of the body and around the second aperture; and
a fourth hexagonal fastener recess formed at least partially below the lower surface of the body and around the second aperture.
17. The fastener of claim 16 , wherein the first hexagonal fastener recess, the second hexagonal fastener recess, the third hexagonal fastener recess and the fourth hexagonal fastener recesses each have different cross-dimensions.
18. A fastener for use in attaching objects to a strut channel, comprising:
a body having an upper surface and a lower surface;
a first aperture passing through the body between the upper surface and the lower surface;
a first fastener recess recessed in the upper surface of the body and around the first aperture;
a ridge extending from a sidewall surface of first fastener recess and extending into an interior of the first fastener recess, wherein the ridge defines a reduced cross-dimension location in the first fastener recess; and
a first pair of recessed channels recessed in the lower surface of the body, the first pair of recessed channels being parallel and disposed on opposing sides of the first aperture.
