Abstract
Disclosed herein is a clamp for interconnecting two components of a support apparatus such as components of a shoring apparatus for concrete forming systems. A clamp member having a moveable jaw is received for pivotal movement in a housing that is secured to one of the components. A plurality of flutes disposed at an angle to the pivot axis of the clamp member are received in coacting recesses in the housing and a proximal cap maintains the desired position of the clamp member within the housing. Axial movement of the clamp member will pivot the swing arm and a coacting, moveable jaw toward a fixed jaw formed in the housing to releasably secure the clamp to the other component.
Claims17
A clamp for releasably interconnecting a first component and a second component of a support apparatus, the clamp comprising:
- (a) a housing secured to the first component, the housing comprising:
- (i) a clamp pin opening in the housing, having at least one recess formed in the periphery of the opening;
- (ii) a fixed jaw extending from the housing and adapted to engage a first portion of the second component;
- (iii) a moveable jaw pivotably mounted to the housing opposite from the fixed jaw and adapted to engage a second portion of the second component;
- (iv) an upper plate comprising a first opening defined within the upper plate;
- (v) a lower plate comprising a second opening defined within the lower plate,
- wherein the second opening is aligned with the first opening;
- and
- (vi) at least one recess formed in the periphery of each of the openings,
- wherein the first and second openings are sized to receive the clamp pin;
- (b) a clamp pin comprising:
- (i) a pin body having a pivot axis and received within the clamp pin opening of the housing;
- (ii) a swing arm extended generally radially from the pin body and adapted to engage the moveable jaw;
- (iii) a proximal cap disposed at a proximal end of the pin body;
- and
- (iv) at least one flute extended generally radially from the pin and disposed at an angle relative to the pivot axis of the pin and received within the recess, whereby movement of the clamp pin along the pivot axis of the pin will pivot the swing arm and thereby the moveable jaw toward the fixed jaw to securely engage the second component between the jaws,
- wherein a distal surface of the proximal cap is positioned a predetermined distance from a distal surface of the swing arm such that when the distal surface of the swing arm is in contact with a top surface of the lower plate, the distal surface of the proximal cap is in contact with a top surface of the upper plate.
A clamping member for securing a first component to a second component of a shoring apparatus, the clamping member comprising:
- (a) a housing, comprising:
- (i) a first jaw portion and a second jaw portion, the first and second jaw portion shaped to engage the first component;
- (ii) a pin opening;
- (iii) a first plate;
- and
- (iv) a second plate;
- and
- (b) a pin shaped to be disposed within the pin opening the pin comprising:
- (i) a pin body;
- (ii) a swing arm extended from the pin body;
- (iii) a pin head disposed at one end of the pin body;
- and
- (iv) at least one flute extending from the pin body, the flute disposed at an angle relative to a longitudinal axis of the pin,
- wherein striking of the pin head causes longitudinal movement of the pin when the pin is inserted into the pin opening,
- wherein longitudinal movement of the pin causes rotational movement of the first jaw portion relative to the second jaw portion, and
- wherein the pin head is positioned a predetermined distance from a distal surface of the swing arm such that when the distal surface of the swing arm is in contact with the second plate, the pin head is in contact with the first plate.
A clamp comprising:
- (a) a housing comprising:
- (i) a clamp pin opening in the housing, having at least one recess formed in the periphery of the opening;
- (ii) a fixed jaw extending from the housing;
- (iii) a moveable jaw pivotably mounted to the housing opposite the fixed jaw;
- (iv) an upper plate;
- and
- (v) a lower plate
- (b) a clamp pin comprising:
- (i) a pin body having a longitudinal axis and shaped to be received within the clamp pin opening;
- (ii) a swing arm extended generally radially from the pin body and adapted to engage the moveable jaw;
- (iii) a pin head disposed at a proximal end of the pin body;
- and
- (iv) at least one flute extended generally radially from the pin and disposed at an angle relative to the longitudinal axis of the pin and received within the recess, whereby movement of the clamp pin along the longitudinal axis causes pivoting of the swing arm and thereby the rotational movement of the moveable jaw toward the fixed jaw
- wherein the pin head is positioned a predetermined distance from a distal surface of the swing arm such that when the distal surface of the swing arm is in contact with the lower plate, the proximal cap is in contact with the upper plate.
