Abstract
Abstract A clamp device having a main body and a pivotable, pipe clamping holder. A first bolt and nut connect the main body and the pivotable holder and allow them to pivot with reference to the first bolt. Another bolt is pivotally connected to the main body and can be swung in a groove in the second holder and the other nut is held in the groove by a respective nut. The two bolts cooperate to clamp a pipe. An arm to one side of the second holder and the main body is operable for pivoting the second holder around the second bolt to selectively open or close the clamping against the main body. A spring on the first bolt biases the second holder contrary to the force applied to the arm. The main body extends to a further clamping hole. An additional pipe holding, adjustable angle member may be installed in the further hole.

Claim 1
Independent Claim
335 words
A clamp device for clamping a pipe, the clamp comprising: a main body having a first holder with a surface for engaging the pipe to be clamped; a second holder with a surface in opposition to the surface of the main body, whereby the pipe may be clamped between the first holder on the main body and the second holder; a first tightening bolt pivotally attached to the main body at one side of the first holder and pivotable to engage the second holder and to swing away from the second holder, the second holder having a groove therein into which the first bolt is swingable; a first nut to be screwed onto the first bolt while the first bolt is in the groove in the second holder thereby clamping the main body and the second holder together by the first bolt and the first nut; an installation hole extending through the second holder at the opposite side of the first holder of the main body from the first bolt; a second bolt spaced on the other side of the first holder from the first bolt and the second bolt extending through the installation hole in the second holder; the installation hole being shaped so that the second holder may be swingable with respect to the clamp main body and with respect to the second bolt held in the main body; a second nut screwed onto the second bolt and located at the side of the second holder away from the main body, whereby the second bolt and second nut hold the second holder to the main body and clamp the second and first holders to a pipe in cooperation with the first bolt and the first nut; an arm protruding to the side of the second holder past the second bolt, and away from the first bolt, the arm being operable to pivot the second holder with respect to the second bolt and nut to open the clamping of the first and second holders.
Claim 2
Dependent Claim
335 words
A clamp device for clamping a pipe, the clamp comprising: a main body having a first holder with a surface for engaging the pipe to be clamped; a second holder with a surface in opposition to the surface of the main body, whereby the pipe may be clamped between the first holder on the main body and the second holder; a first tightening bolt pivotally attached to the main body at one side of the first holder and pivotable to engage the second holder and to swing away from the second holder, the second holder having a groove therein into which the first bolt is swingable; a first nut to be screwed onto the first bolt while the first bolt is in the groove in the second holder thereby clamping the main body and the second holder together by the first bolt and the first nut; an installation hole extending through the second holder at the opposite side of the first holder of the main body from the first bolt; a second bolt spaced on the other side of the first holder from the first bolt and the second bolt extending through the installation hole in the second holder; the installation hole being shaped so that the second holder may be swingable with respect to the clamp main body and with respect to the second bolt held in the main body; a second nut screwed onto the second bolt and located at the side of the second holder away from the main body, whereby the second bolt and second nut hold the second holder to the main body and clamp the second and first holders to a pipe in cooperation with the first bolt and the first nut; an arm protruding to the side of the second holder past the second bolt, and away from the first bolt, the arm being operable to pivot the second holder with respect to the second bolt and nut to open the clamping of the first and second holders.
Claim 3
Dependent Claim
60 words
The clamp device of claim 1, further comprising a first spring at the second bolt for urging the second holder away from the clamp main body at the second bolt, and operation of the arm of the second holder to pivot the second holder with respect to the second bolt is in opposition to the bias of the first spring.
Claim 4
Dependent Claim
56 words
The clamp device of claim 2, further comprising a second spring on the first bolt normally biased against the main body near where the first bolt is pivotally attached to the main body and the bias of the second spring resisting the pivoting of the first bolt around its pivot with respect to the main body.
Claim 5
Dependent Claim
50 words
The clamp device of claim 2, further comprising a guide window in the clamp main body positioned for the arm of the second holder to enter the guide window, whereby the arm may move through the window and the window regulates the movement of the arm in the width direction.
Claim 6
Dependent Claim
93 words
The clamp device of claim 2, wherein the second holder has concave groove with a curved face in the width direction and that crosses the through hole for the second bolt in the second holder; the second nut has a projection with a curved surface in the width direction that extends across the second nut and is in opposition to the concave groove in the second holder for forming a locking connection between the second nut and the second holder which inhibits rotation of the second nut with respect to the second holder.
Claim 7
Dependent Claim
50 words
The clamp device of claim 2, wherein the main body extends beyond and away from the second holder in a continuation of the main body, the continuation having a terminal end region, a third hole being formed through the terminal end region, and a third holder for the third hole.
Claim 8
Dependent Claim
56 words
The clamp device of claim 6, wherein the main body is cut through the terminal end region and to the third hole defining cut portions; a third bolt extends between the cut portions of the terminal end region, and a third nut is tightened on the third bolt for clamping an object in the third hole.
Claim 9
Dependent Claim
96 words
The clamp device of claim 7, further comprising a third holder with a body portion in the third hole; a pipe insertion and angle adjustment member positioned in the third holder; a fourth tightening bolt, a hole through the fourth bolt; a fourth nut for being tightening on the fourth tightening bolt for tightening the fourth tightening bolt so as to hold a rod in the hole in the fourth tightening bolt and against the angle adjustment member for holding the orientation and position of the rod with respect to the body of the third holder.
Claim 10
Dependent Claim
54 words
The clamp device of claim 1, further comprising a spring on the first bolt normally biased against the main body near where the first bolt is pivotally attached to the main body and the bias of the spring resisting the pivoting of the first bolt around its pivot with respect to the main body.
Claim 11
Dependent Claim
78 words
The clamp device of claim 9, further comprising a washer at the first bolt and positioned for engaging the main body and the spring at the first bolt biasing the washer against the main body, the main body being shaped so as to cooperate with the washer biased against it to resist pivoting of the first bolt with respect to the body, and the washer being in sliding contact with the outer peripheral surface of the main body.
Claim 12
Dependent Claim
71 words
The clamp device of claim 9, further comprising a groove in the clamp main body and the first bolt being pivotally mounted to the main clamp body at the groove; and an insertion groove at an end of the second holder, and the first bolt being pivotable into the insertion groove, and the first nut on the first bolt holding the first bolt in the insertion groove on the second holder.
