Abstract
Abstract A two-piece clamping assembly includes a first clamp member and a second clamp member constructed and arranged to cooperate to define first and second pin bores. The first bore is disposed generally transverse with respect to the second bore. A rod is threaded into an axial bore through a portion of the first clamp member and extends through the second clamp member beyond an end surface thereof. A control knob is coupled to the end of the rod. The control knob includes a seating surface constructed and arranged to engage the end surface of the second clamp member, whereby manual movement of the control knob such that the seating surface contacts the end surface, clamps the second clamp member between the first clamp member and control knob so as to clamp associated pins in the pin bores. The first and second clamp members are constructed and arranged in such a manner that all operative threads of the rod are disposed within the axial bore.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
354 words
A clamping assembly comprising: a first clamp member having a first core portion and first and second arms extending from the first core portion in directions generally transverse to each other, said first core portion including a first bore therethrough extending in a direction generally transverse to a longitudinal axis of said first arm, at least a portion of said first bore defining screw threads, each said first and second arm having a recess therein, a second clamp member having a second core portion and first and second arms extending from the second core portion in a direction generally transverse to each other, said second core portion including a second bore therethrough extending generally parallel to a longitudinal axis of said first arm thereof, each said first and second arm of said second clamp member having a recess therein, said first and second clamp members being constructed and arranged to cooperate such that said first bore aligns with said second bore to define an axial bore, said recess of said first arm of said first clamp member and said recess of said second arm of said second clamp member cooperate to define a first pin holding bore and said recess of said second arm of said first clamp member and said recess of said first arm of said second clamp member cooperate to define a second pin holding bore disposed generally transverse with respect to said first pin holding bore, a rod having first and second ends and a portion thereof defining screw threads, said rod being threaded into said portion of said first bore and extending through said axial bore and beyond an end surface of said second core portion; and a control knob coupled to said second end of said rod, said control knob including a seating surface constructed and arranged to engage said end surface of said second core portion, whereby, manual movement of said control knob such that said seating surface contacts said end surface, clamps the second clamp member between the first clamp member and the control knob so as to clamp associated pins in said pin holding bores.
Claim 2
Dependent Claim

A clamping assembly comprising: a first clamp member having a first core portion and first and second arms extending from the first core portion in directions generally transverse to each other, said first core portion including a first bore therethrough extending in a direction generally transverse to a longitudinal axis of said first arm, at least a portion of said first bore defining screw threads, each said first and second arm having a recess therein, a second clamp member having a second core portion and first and second arms extending from the second core portion in a direction generally transverse to each other, said second core portion including a second bore therethrough extending generally parallel to a longitudinal axis of said first arm thereof, each said first and second arm of said second clamp member having a recess therein, said first and second clamp members being constructed and arranged to cooperate such that said first bore aligns with said second bore to define an axial bore, said recess of said first arm of said first clamp member and said recess of said second arm of said second clamp member cooperate to define a first pin holding bore and said recess of said second arm of said first clamp member and said recess of said first arm of said second clamp member cooperate to define a second pin holding bore disposed generally transverse with respect to said first pin holding bore, a rod having first and second ends and a portion thereof defining screw threads, said rod being threaded into said portion of said first bore and extending through said axial bore and beyond an end surface of said second core portion; and a control knob coupled to said second end of said rod, said control knob including a seating surface constructed and arranged to engage said end surface of said second core portion, whereby, manual movement of said control knob such that said seating surface contacts said end surface, clamps the second clamp member between the first clamp member and the control knob so as to clamp associated pins in said pin holding bores.
Claim 3
Dependent Claim
28 words
The clamping assembly according to claim 1, wherein said first and second clamp members cooperate to define a smoothly contoured generally L-shaped configuration when in a clamping position.
Claim 4
Dependent Claim
18 words
The clamping assembly according to claim 1, wherein said first and second clamp members are made from Acetal.
Claim 5
Dependent Claim
19 words
The clamping assembly according to claim 1, wherein said first and second clamp members are made from reinforced nylon.
Claim 6
Dependent Claim
18 words
The clamping assembly according to claim 1, wherein said first and second clamp members are made from polyester.
Claim 7
Dependent Claim
18 words
The clamping assembly according to claim 1, wherein said first and second clamp members are made from polyvinylchloride.
Claim 8
Dependent Claim
56 words
The clamping assembly according to claim 1, wherein, in a clamping position, a surface of said first clamp member and a surface of said second clamp member are engaged, defining gaps adjacent each of said pin holding bores such that surfaces defining said pin holding bores do not completely surround an associated pin when clamped therein.
Claim 9
Dependent Claim
22 words
The clamping assembly according to claim 1, wherein said recesses are part-circle recesses defining said pin holding bores of generally cylindrical configuration.
Claim 10
Dependent Claim
37 words
The clamping assembly according to claim 1, wherein said first and second clamp members are constructed and arranged in such a manner that all said screw threads of said rod are disposed substantially within the axial bore.
