Abstract

A clamp including two mutually opposed substantially L-shaped members pivotably connected to an intermediate holder supporting the side profile sections of the panel frames to be secured, wherein the two L-shaped members are pivotably interconnected via a central shaft extending through the intermediate holder and said L-shaped members are further pivotably connected to said intermediate holder via two further transverse shafts extending through respective mounting apertures in the intermediate holder.

Claims

1. An adjustable clamp for securing shuttering panels, comprising:

a pair of substantially L-shaped members arranged opposite one another;

an intermediate support on which the pair of L-shaped members articulate;

wherein one arm of each L-shaped member has an end profile adapted for coupling the one arm to the profile sections of the frames of the panels to be clamped, while another arm of each L-shaped member receives a displacement device for effecting rotation of the other arm, causing the opening and closing of the L-shaped members of the clamp;

wherein the pair of L-shaped members are articulated by a central pin which passes through the intermediate support, and each of the L-shaped members is further articulated on the intermediate support by means of first and second transverse pins which pass through respective elongated holes in the intermediate support.

2. The adjustable clamp of claim 1, wherein the central pin for articulation of the two L-shaped members with each other passes through an inside of an elongated hole in the intermediate support, perpendicular to the longitudinal axis of the intermediate support.

3. The adjustable clamp of claim 1, wherein the central pin of the two L-shaped members passes through ahead of a threaded rod coupled to the intermediate support, which has incorporated on it a fixing nut which acts on a face one of the faces of the intermediate support.

4. The adjustable clamp of claim 1, wherein the first transverse pin passes through an inside of the respective elongated hole, the respective elongated hole being parallel with an elongated hole receiving the central pin for articulation of both L-shaped members, and wherein the second transverse pin passes through an inside of the respective elongated hole in a shape of an arc of a circle.

5. The adjustable clamp of claim 4, wherein both a center and a radius of the circle of the respective elongated hole in a shape of an arc are such that the circle and the radius permit an adjustment of the clamp so that points of attack of the arms of the clamp on the profile sections are displaced on a straight line parallel to the intermediate member, in order to permit the adjustment of the clamp so that the points of attack of the arms of the clamp on the profile sections remain parallel with respect to a face of the intermediate support on which the profiles section bear.
