Abstract: A device for releasably holding the boot support of a cross-country ski binding against pivotal movement relative to the ski has a retainer which is mounted on two pairs of mutually inclined links. The lower ends of the links are pivoted to the ski and the upper ends of the links are pivoted to spaced-apart portions of the retainer so as to compel the latter to move along a path which is at least substantially parallel to the upper side of the ski between an operative front end position and an inoperative rear end or retracted position. The retainer can be moved between such positions by a combination of a link which is directly pivoted to the rear part of the retainer and a lever which is fulcrumed on the ski and whose forwardly extending arm is articulately connected to the rear end of the link. The rearwardly extending arm of the lever can be pivoted by hand or by the tip of a ski pole in order to move the retainer to the operative position. The retainer is moved to inoperative position in response to pivoting of the link by the tip of a ski pole. The pin which couples the lever to the link is moved to one side of a dead-center position in response to movement of the retainer to its operative position and to the other side of such dead-center position in response to retraction of the retainer to its inoperative position.

Abstract: A handle device for a door which is formed of an assembly installed in a door panel and has a handle grip connected thereto by a pivot pin. A latch is retractably mounted to the assembly and is interlocked with the handle grip. An actuating lever is pushed by the handle grip to move the latch. A reset lever drives the actuating lever when pushed by a push rod extending inside the door. A lock mounted on the assembly has a cam secured to a rotor, serves to release the engagement between a lock plate which is secured to the assembly and adapted to check the slide of the latch, and the latch. When the push rod turns the reset lever, engagement between the lock plate and the latch is released and the latch slides and is retracted by turning the actuating lever.
