Pivotable clamp
View Patent ↗A pivotable clamp is provided. One embodiment of the present invention comprises a clamp that includes a first member that is pivotably coupled to a second member. A third member is pivotally coupled to the second member. The first member is sized to slidably engage a rail that is part of a retractable cover system. An alternative embodiment of the present invention comprises a pivot block that includes a pivot slot. A rail engaging member is slidably coupled to the pivot block, and a pivot arm is pivotably mounted in the pivot slot. This embodiment may include a second pivot slot sized to pivotably receive the pivot arm.
1. A clamp, comprising:
a first member having portions substantially perpendicular to each other forming first and second engagement surfaces of the clamp, the first member being coupled to a second member;
a third member having first and second ends, with the first end of the third member being pivotally coupled to the second member, and the second end of the third member forming a third engagement surface of the clamp;
a fastener having a longitudinal axis and being coupled to the first and second members and adapted to move the second member toward the first member along the axis of the fastener thereby causing the second end of the third member to move toward each of the respective first and second engagement surfaces; and
wherein the fastener coupled to the first and second members comprises an externally threaded rod portion comprising a bolt and an internally threaded nut portion comprising a barrel nut.
2. The clamp of claim 1 , wherein the first end of the third member is pivotally coupled to the second member by a cylinder-and-socket coupling.
3. The clamp of claim 1 , wherein the first end of the third member is pivotally coupled to the second member by a hinge having a pin.
4. The clamp of claim 1 , wherein the first member is pivotally coupled to the second member by a cylinder-and-socket coupling.
5. The clamp of claim 1 , wherein the first member is pivotally coupled to the second member by a hinge having a pin.
6. A clamp, comprising:
a first member having portions substantially perpendicular to each other forming first and second engagement surfaces of the clamp, the first member being coupled to a second member;
a third member having first and second ends, with the first end of the third member being pivotally coupled to the second member, and the second end of the third member forming a third engagement surface of the clamp;
a fastener having a longitudinal axis and being coupled to the first and second members and adapted to move the second member toward the first member along the axis of the fastener thereby causing the second end of the third member to move toward each of the respective first and second engagement surfaces; and
wherein the fastener passes through an aperture in the first member and the fastener further is coupled to the first end of the third member.
7. The clamp of claim 6 , wherein the fastener further passes through an aperture in the second member.
8. The clamp of claim 1 , wherein the first member slidingly engages the second member.
9. The clamp of claim 8 , wherein the second member comprises a pivot block pivotally coupled to the first end of the third member.
10. The clamp of claim 8 , wherein the second member comprises a pivot block having a plurality of spaced apart positions by which the pivot block may be pivotally coupled to the first end of the third member.
11. The clamp of claim 1 , wherein the first member comprises at least two portions coupled to each other to form the first and second engagement surfaces.
12. The clamp of claim 11 , wherein the two portions of the first member are adapted to be joined by sliding engagement with each other.
13. The clamp of claim 11 , wherein the first member comprises at least three portions coupled to each other to form the first and second engagement surfaces.
