Abstract

A mechanism for clamping first and second stabplates together comprises a pivoted cam member and clamping means for co-operating with the cam member. The mechanism is such that the cam member is displaceable between a first position in which, in co-operation with the clamping means, it clamps the stabplates together and a second position in which it has rotated to be between the stabplates with the stabplates separate from each other.

Claims (21)

1. A mechanism for clamping first and second stabplates together, the mechanism comprising:

a first pivoted cam member;

a clamping means in cooperation with the first pivoted cam member; and

a second cam member, wherein the first and second cam members are pivotable to rotate in opposite directions, each cam member cooperating with the clamping means;

wherein the first pivoted cam member is displaceable between a first position and a second position;

wherein in the first position, in cooperation with the clamping means, the mechanism clamps the stabplates together; and

wherein in the second position the mechanism is configured to rotate between the stabplates to separate the stabplates from each other.

2. The mechanism according to claim 1 , further comprising a locking member between the cam members, the locking member being displaceable to cause pivotal rotation of the cam members.

3. The mechanism according to claim 1 , further comprising a pivot member between the cam members to which each of the cam members is pivotally attached.

4. A method for clamping first and second stabplates together or unclamping first and second stabplates from each other, the method comprising:

providing a mechanism comprising a first pivoted cam member and a clamping means in cooperation with the first pivoted cam member; and

displacing the first pivoted cam member between a first position and a second position;

wherein the mechanism is received via a central orifice of each of the stabplates and wherein the mechanism further comprises a second cam member, and wherein the first and second cam members pivotally rotate in opposite directions, each of which cooperate with the clamping means;

wherein in the first position, in cooperation with the clamping means, the mechanism clamps the stabplates together; and

wherein in the second position the mechanism is configured to rotate between the stabplates to separate the stabplates from each other.

5. The method according to claim 4 , wherein the cam members are displaced by a locking member between the cam members to cause pivotal rotation of the cam members.

6. The method according to claim 4 , wherein the cam members are pivotally attached for rotation to a pivot member between the cam members.

7. The mechanism according to claim 2 , further comprising a pivot member between the cam members to which each of the cam members is pivotally attached.

8. The mechanism according to claim 7 , wherein the clamping means further comprises at least one pin and at least one slot which are slidable relative to each other, wherein displacing the locking member is caused by a relative movement of the at least one pin and the at least one slot.

9. The method according to claim 5 , wherein the cam members are pivotally attached for rotation to a pivot member between the cam members.

10. The method according to claim 9 , wherein the clamping means further comprises at least one pin and at least one slot which are slidable relative to each other, wherein displacing the locking member is caused by a relative movement of the at least one pin and the at least one slot.
