Self-adjusting end clamp
Self-adjusting end clamps are disclosed. The clamps may include a top member and a bottom member having vertically arranged holes. As a bolt placed in the vertically arranged holes is tightened, the top and bottom members move toward one another to grip an object therebetween.
1. A self-adjusting end clamp, comprising:
a top portion with a lip;
a bottom portion with a lip, a bolt receiving portion, and a ridge, wherein the ridge protrudes toward the lip of the top portion and laterally separates parallel surfaces of the lip of the bottom portion and of the bolt receiving portion, and wherein the distance between the lip of the top portion and a surface of the ridge facing the lip of the top portion is less than the distance between the lip of the top portion and the bolt receiving portion; and
a bolt extending between an aperture of the top portion and an aperture of the bolt receiving portion, wherein when the bolt is tightened the lips of the top portion and the bottom portion move towards each other.
2. A self-adjusting end clamp, comprising:
a top member, comprising:
a main body portion comprising a first wall, a second wall, a third wall, and a fourth wall, wherein the first wall opposes the third wall, and wherein the second wall opposes the fourth wall; and
a lip extending from the main body portion, wherein:
the lip is coplanar with the first wall and perpendicular to the second wall;
the first and third walls each comprise a hole configured to receive a bolt; and
the holes are vertically aligned; and
a bottom member comprising a first portion and a second portion, wherein:
the first and second portions are perpendicular and integrally formed;
the first portion is arranged parallel to the first and third walls of the main body portion of the top member and comprises:
a hole for receiving the bolt; and
a ridge extending away from and across a width of the first portion; and
the second portion abuts the fourth wall of the main body portion of the top member.
3. The self-adjusting end clamp of claim 1 , wherein:
the top portion comprises a main body having a substantially rectangular cross-section; and
the lip of the top portion extends from the main body.
4. The self-adjusting end clamp of claim 3 , wherein:
the lip of the top portion is arranged coplanar with a first side of the main body and perpendicular with a second side of the main body.
5. The self-adjusting end clamp of claim 4 , wherein the ridge is vertically aligned with the second side of the main body.
6. The self-adjusting end clamp of claim 3 , wherein the bolt extends fully through the main body.
7. The self-adjusting end clamp of claim 1 , the bottom portion being L-shaped.
8. The self-adjusting end clamp of claim 1 , wherein the ridge, the lip of the bottom portion, and the aperture are arranged on a first arm of the L-shaped bottom portion.
9. The self-adjusting end clamp of claim 8 , wherein a second arm of the L-shaped bottom portion engages the top portion on a side of the top portion opposing the lip.
10. The self-adjusting end clamp of claim 8 , wherein the parallel surfaces of the lip and the bolt receiving portion abut the ridge.
11. The self-adjusting end clamp of claim 1 , comprising:
a clip portion extending obliquely from the bottom portion from a surface opposing the lip.
12. The self-adjusting end clamp of claim 1 , the aperture of the bottom portion being a threaded aperture configured to threadably receive the bolt.
13. The self-adjusting end clamp of claim 2 , the main body portion having a substantially rectangular cross-sectional shape, wherein the second wall and the fourth wall extend perpendicularly from the first wall, and the third wall extends perpendicularly between the second wall and the fourth wall.
14. The self-adjusting end clamp of claim 2 , wherein the surfaces of the first portion are substantially parallel on either side of the ridge.
15. The self-adjusting end clamp of claim 2 , wherein the second wall of the main body is arranged proximally with respect to the lip and the fourth wall of the main body is arranged distally with respect to the lip.
16. The self-adjusting end clamp of claim 2 , comprising:
a clip portion extending obliquely from a second side of the second portion of the bottom member opposing a first side that engages the fourth wall of the main body.
17. The self-adjusting end clamp of claim 2 , wherein the ridge is arranged between the lip and the threaded hole of the bottom portion.
18. The self-adjusting end clamp of claim 2 , wherein the hole of the bottom member is a threaded hole for threadably receiving the bolt.
