Pipe clamp with releasable clamp body
View Patent ↗A clamp body is provided with a channel formed in the clamp body and a retainer is movably mounted in the clamp body. A jaw is mounted on the clamp body and an end cap blocking one end of the channel.
1. A clamp comprising:
a support comprising a first end and a second end and defining a support axis;
a workpiece engaging element mounted to the support;
a clamp body releasably connected to the support through a channel formed in the clamp body wherein the first end is inserted into the channel, the clamp body comprising:
a jaw operatively connected to the clamp body and opposing the workpiece engaging element;
a retainer movably mounted to the clamp body to engage the support selectively and thereby to hold the clamp body selectively against movement with respect to the support in at least a first direction along the support axis; and
an end cap opposite the jaw on the clamp body wherein the clamp body is restrained from motion along the support axis towards the workpiece supporting element beyond the first end of the support.
2. The clamp in claim 1 wherein the retainer comprises a tab positioned around the support, coupled to the clamp body, and movable between an inclined position, in which the retainer holds the clamp body against movement in at least the first direction with respect to the support, and a release position, in which the retainer accommodates movement of the clamp body in the first direction with respect to the support.
3. The clamp in claim 1 wherein the retainer is coupled to the clamp body by a spring mechanism which is partially compressed when the retainer is the inclined position, and fully compressed when the retainer is in the release position.
4. The clamp body in claim 1 wherein the retainer comprises a tab coupled to the clamp body, and movable between an inclined position and a release position.
5. The clamp body in claim 4 wherein the retainer is coupled to the clamp body by a spring mechanism which is partially compressed when the retainer is the inclined position, and fully compressed when the retainer is in the release position.
6. The clamp in claim 1 wherein the jaw is supported on a workpiece supporting element, the clamp body being connected to the workpiece supporting element by a screw.
7. The clamp in claim 1 wherein the jaw is supported on a workpiece supporting element, the workpiece supporting element being movable relative to the clamp body.
8. The clamp in claim 1 wherein the workpiece engaging element is movably supported on the support.
9. The clamp in claim 1 further including a second retainer movably mounted to the workpiece engaging element to engage the support selectively and thereby to hold the workpiece engaging element selectively against movement with respect to the support in at least one direction along the support axis.
10. The clamp in claim 9 wherein the second retainer comprises a tab positioned around the support, coupled to the workpiece engaging element, and movable between an inclined position, in which the second retainer holds the workpiece engaging element against movement in at least one direction with respect to the support, and a release position, in which the retainer accommodates movement of the workpiece engaging element in the one direction with respect to the support.
11. The clamp in claim 10 wherein the second retainer is coupled to the workpiece engaging element by a second spring mechanism which is partially compressed when the second retainer is the inclined position, and fully compressed when the retainer is in the release position.
12. The clamp in claim 6 wherein rotation of the screw moves the workpiece supporting element relative to the screw.
