Fixing device having two pivotally interconnected clamps

Claim 2

A fixing device as claimed in claim 2, wherein said tubular member includes a knurled outside wall that frictionally engages with the inner wall of each aligned throughbore so that said first and second clamps retain their relative angular position with each other during assembly.

Claim 3

A fixing device as claimed in claim 1 or 2, wherein said first and second clamps are of identical construction.

Claim 4

A fixing device as claimed in claim 3, wherein each first and second clamp includes a pair of semi-cylindrical, pivotally interconnected members, said first clamping means and adjustable clamping means each being a thumbscrew for coupling said two members together in clamping engagement.

Claim 5

A holding device for mounting an article in a substantially stationary position relative to a support member, comprising: (a) a first clamp having an axially extending opening and clamping means connected to the first clamp that clamps a mount received in said opening, said mount having a mounting surface receiving and supporting the article; (b) a second clamp having an axially extending opening receiving the support member, said second clamp including adjustable clamping means selectively clamping the second clamp in a desired angular and axial position relative to the support member; (c) coupling means engaging each said first and second clamps connecting said first and second clamps together, said coupling means enabling manual pivoting movement of the first and second clamps with respect to each other about a coupling axis substantially perpendicular to axial directions of said first and second clamps; and (d) selective tightening means connected to said coupling means holding the first and second clamps in fixed positions relative to each other; wherein each first and second clamp is formed with a throughbore extending in a direction substantially perpendicular to the axial direction of each clamp, each throughbore being selectively positioned in axial alignment with the other throughbore coupling the clamps together with said coupling means and being generally tapered in a direction toward the other clamp, said tightening means including a pair of members each having a tapered surface corresponding to a tapered inner wall of said aligned throughbores pressing portions of the coupling means against the inner walls of said throughbores when said tightening means is tightened.

Claim 6

A holding device for mounting an article in a substantially stationary position relative to a support member, comprising: (a) a first clamp having an axially extending opening and clamping means connected to the first clamp that clamps a mount received in said opening, said mount having a mounting surface receiving and supporting the article; (b) a second clamp having an axially extending opening receiving the support member, said second clamp including adjustable clamping means selectively clamping the second clamp in a desired angular and axial position relative to the support member; (c) coupling means engaging each said first and second clamps connecting said first and second clamps together, said coupling means enabling manual pivoting movement of the first and second clamps with respect to each other about a coupling axis substantially perpendicular to axial directions of said first and second clamps; and (d) selective tightening means connected to said coupling means holding the first and second clamps in fixed positions relative to each other; wherein each first and second clamp is formed with a throughbore extending in a direction substantially perpendicular to the axial direction of each clamp, each throughbore being selectively positioned in axial alignment with the other throughbore coupling the clamps together with said coupling means and being generally tapered in a direction toward the other clamp, said tightening means including a pair of members each having a tapered surface corresponding to a tapered inner wall of said aligned throughbores pressing portions of the coupling means against the inner walls of said throughbores when said tightening means is tightened.
