An ascender device for a double rope is composed of two identical ascenders, the flanges of which are reversed by pivoting through 180° with respect to one another along a vertical axis extending parallel to the two troughs. The two grips are symmetrical with respect to the vertical axis so as to be able to be held at the same time by the user's right hand and left hand.

An ascender device for belaying on a fixed rope, comprising a body with a trough, and an actuating lever having a pivot, a cam for clamping the rope, and a hole for attaching a safety means. A connecting arm with a button-hole is articulated between the pivot and body to move the actuating lever between an inactive position facilitating insertion of the rope in the trough and an active position wherein the ends of the pivot are housed in aligned recesses acting as bearings. A double lock comprises a first lock and a second lock to secure the two opposite ends of the pivot in the recesses, each lock being associated with an unlocking tab for releasing same.

An ascender/descender appliance for ascending and descending on a rope, comprising a body having attachment means to be connected to the user's harness and a clamping device able to be released on load. The clamping device is arranged outside the body and comprises a chain of metal links constituted by a succession of friction elements articulated on one another by connecting rods to form a series of gaps for the rope to pass in zigzag manner. Means are associated with the top link to trigger clamping of the ascender device.

The invention relates to an apparatus for securing rescue operations by helihoisting that comprises three attachment means to the helicopter, the lifeguard and the belay tether. A trigger control mechanism includes a mobile pawl pivotally mounted on the hook between a closing position and a release position of the opening, respectively for maintaining the tether in the hook and for releasing the same, and a latch submitted to the action of a polarization spring for locking said pawl in the closed position in the absence of a tension on the first attachment means, and for unlocking said pawl when the force applied on the first attachment means exceeds that of the polarization spring. The assembly is arranged for triggering the automatic release of the belay tether that remained attached when the tensioning by the helicopter traction cable exceeds a predetermined threshold.

An ascender for a fixed rope comprising a metal flange-plate equipped with a trough for housing the rope and with a swivelling trigger designed to block the rope against the inner surface of the trough when the flange-plate is solicited in the downwards direction. The outside surface of the trough comprises an ergonomic grip for the ascender to be totally held in the hand. The grip extends over the whole length of the trough, and the pivot-pin of the trigger is located at an intermediate level between the opposite ends of the grip.

A safety helmet with a crown comprises a head-band with a strip adjustable by means of a first mechanism with inverter pinion cooperating with a first crown-wheel and a second crown-wheel located at the two opposite ends of the strip. An operating ring is accessible from outside to perform adjustment with one hand when the helmet is on the user's head. The double crown-wheel is arranged on the side of the crown and enables perfect centering to be achieved regardless of the size of the head-band.Application: potholing, mountaineering, construction sites, etc.
