Abstract: A clamp fitment includes a pair of holding members each capable of clamping a pipe section, a coupler mounted between both the holding members for relatively rotatably but unseparatably coupling the holding members, and a lock mechanism mounted between both the holding members for restraining the relative rotation of the holding members at any time in positions in which the pipe sections clamped in the holding members intersect each other at right angles. The single clamp fitment for connecting the pipe sections can be used properly as either of "swivel type" in which the angle of intersection of the pipe sections can be freely selected and "orthogonal type" for unifying the pipe sections in a square fashion. This eliminates the need for a worker to carry two kinds of clamp fitments to a working field, leading to simplified handling and management of the clamp fitment.

The base-jaw surface 17 subtends more than 180 degrees to snap fit with the tube 15, and opening of the closure jaw 12 is limited by a projection 20 (or otherwise, FIG. 7 ) for support of the tube 15 (FIG. 2). Closing of the jaw 12 may be tripped by entry of the tube 15 (FIG. 6 ), and the jaws may be abrasive-surfaced (FIG. 5 ) to improve grip. The lever 13 may be selectively locked in the actuated condition (FIGS.

Abstract: The present invention provides a clamp which can be used to secure an accessory member to an abductor bar of an orthopedic-surgical table. The clamp includes a clamp block pivotally mounted on the clamp and oriented with respect to the clamp to clamp an object therebetween. A lever having a cam surface is mounted on the clamp so that the cam surface coacts with the internal mechanism of the clamp to orient the clamp block in an unclamped, intermediate and clamped position. When the clamp is in the intermediate position, the clamp loosely engages the clamped object so that relative motion of the clamp and clamped object can occur. Because the clamp can be stabilized on the clamped object by orienting it in the intermediate position the operator does not need to use a second hand to prevent the clamp from falling off the clamped object while the first hand positions and tightens the clamp. Thus, the clamp can be secured to the clamped object in a one handed operation.
