<p>An adjustable clamp for holding objects securely in position comprising at least one arm (1) which exhibits one articulated arrangement (4, 5) arranged at each of the two ends of the arm. Said articulated arrangement exhibits two pivot pins (6, 8, 7, 9) arranged at an angle to each other. The object (36) is held securely by means of a clamping arrangement attached to the articulated arrangement. Each articulated device (4, 5) exhibits, free to move in relation to the arm (1), an articulated body (15) with a curved articulated surface (16) which is in contact with and is so arranged as to move relative to a corresponding curved articulated surface (17) in an articulated component (12) attached to the ends (2, 3) of the arm. The articulated body also exhibits a flat articulated surface (18) which is in contact with and may be turned relative to a corresponding flat surface. One of the pivot pins (8) in each articulated arrangement (4, 5) extends through the articulated component and the articulated body and forms a releasable locking arrangement for the arm and for the clamping arrangement. The locking arrangement is capable of adjustment between a locked position in which the articulated surfaces are tightly clamped to each other in a pre-set position by means of said pivot pin and a released position in which the articulated surfaces are capable of moving relative to each other. The articulated components (12) of the arm (1) are executed in the form of hook-like components, each of which is open to the side in its own particular direction relative to the longitudinal direction of the arm.</p> |
