Abstract: A safety ski binding includes a binding member guided in the longitudinal direction of a ski on a guide rail and releasably fixable in different positions therealong by an adjusting arrangement, the binding member being under the influence of at least one pressing spring which acts in the longitudinal direction of the ski and which facilitates compensation for play existing between the binding member and the guide rail. The pressing spring is arranged in a spring cage which has a crosswall and a bottom. To provide a constant pressure, the spring cage is provided with at least two downwardly convex leaf springs, or with at least two longitudinal ribs which extend along the two sides of the bottom and are downwardly convex and resilient in a section of their longitudinal length.

Abstract: A heel holder including a base plate on which is arranged a bearing block which can be pivoted laterally. A swivel head is supported in the bearing block on a transverse axle. Between the base plate and the bearing block there is provided a return spring. A locking mechanism is provided in addition, which locking mechanism holds the bearing block in its centered position. In order to hold the bearing block in the heel holder with pressure, the invention provides that the base plate carries a rectangular projection on its upper side, with which projection is associated a recess in the base of the bearing block, and that above the projection there is arranged the locking mechanism which acts through a frictional connection.

Abstract: A sole-support device consisting of a support member and a continuous or endless band guided transversely with respect to the longitudinal direction of the ski on the support member. In order to guarantee in such a device that a secure support of the sole of the boot on the band occurs and in order to avoid friction between the sole of the boot and the support member, the band is supported with its upper reach in a groove of the support member, the upper side of a front section of the band lying in a plane that is higher than a horizontal plane of a boundary edge of the front wall of the groove, the upper side of a rear section of the band being aligned with an upper boundary edge of a rear wall of the groove or in a horizontal plane which lies lower than the boundary edge.

Abstract: A ski brake (1) comprising two wire-brake arms (7) pivotally supported in a base plate (2), which wire-brake arms can be pivotally moved into their ready or retracted position by pressing down an operating pedal (5) against the force of an erecting spring (6). The end sections (7d) of the wire-brake arms (7) are housed in the operating pedal (5) and are connected by a connecting spring (8), to which an intermediate member (9) is hinged. An extension (9b) of the intermediate member (9) is supported on a support surface (2f) of the base plate (2). In order to enable a reliable functioning of this ski brake (1) also under difficult conditions and in order to prevent a snagging of the wire-brake arms (7) on the upper side or the side edges of the ski (10), the invention provides that between the area of the base plate (2) carrying the support surface (2f) and the crossbar ( 9k) of the intermediate member (9) there is provided an elastically flexible interconnection.

Abstract: A gymnastics apparatus having a support rod and a handle bar movable toward and away from one another against the force of a spring. A connecting rod and a pipe is arranged between the support rod and the handle bar, the pipe surrounding the connecting rod and housing the spring. A spring abutment member which opposes the connecting rod can be adjusted in an axial direction in the pipe and can be fixed relative to the pipe. In order to facilitate, in such a gymnastics apparatus, an adjustment to various body sizes, the invention provides that the connecting rod is connected, if desired hingedly, to the support rod and the pipe to the handle bar.

Abstract: A device for effecting longitudinal adjustment of ski binding parts includes a guide rail which is adapted to be mounted on a ski and has a longitudinally extending serrated edge, a guide plate slidably supported on the guide rail for longitudinal movement, a locking member having teeth thereon and supported on the guide plate for movement between first and second positions in which the teeth respectively engage and are free of engagement with the serrated edge, a resilient arrangement which yieldably urges the locking member toward its first position, and an arrangement cooperable with the locking member for releasably holding it in its second position.

Abstract: The underside of a heel holder is guided on a guide rail secured to the upper side of a ski. The guide rail has at least one set of toothed serrations associated with a locking member having corresponding counter serrations. The locking member can be pivoted about a transverse axis. The locking member projects beyond the heel holder toward the tail end of the ski and can be lifted against the force of a spring from and out of the locked position by means of a screw driver. After release by the screw driver, the locking member is swung by the spring into the locked position. A guard plate is provided for covering the teeth of the toothed serrations to prevent damage thereto by the screw driver.

Abstract: The ski brake blades of the present invention have a recess or notch on their inner surface. These notches engage the mandrels of the other ski brake at a point above the blade. The two skis are thus held together.

Abstract: A heel holder includes a base plate, a bearing block supported on the base plate, a binding housing pivotally supported on the bearing block, a control lever pivotally supported on the bearing block and engaging a control element on the binding housing, a release spring which biases the control lever, and a two-arm release lever which is pivotally supported on the control lever and has on a load arm a first extension which can engage a projection on the binding housing and a second extension which can serve as a stop for limiting upward swinging of the binding housing. The swivel axle for the release lever extends through two arcuate holes in sidewalls of the bearing block concentric with the pivot axis of the control lever.

Abstract: A ski binding part, in particular a front jaw, having a guide rail adapted to be fastened to the upper side of a ski and on which is arranged a jaw unit movable in a longitudinal direction of the ski and is secured on a base plate. A housing is provided and a locking mechanism for locking the jaw unit in predetermined sliding positions on the guide rail. The locking mechanism has a locking part which is movably held on the jaw unit and which can be moved by a spring into a form-locking engagement selectively with a complementary locking recess on the guide rail. An operating member is adapted to engage the locking part for effecting a disengagement of the locking part from the complementary locking recess. The operating member is supported on the locking part and is provided with at least two surfaces defining an angle with one another and of which each lies at a different distance from a support point and thus determines the engaged or disengaged position of the locking part.

Abstract: A safety ski binding includes a sole holder which is pivotally supported on a base member for movement upwardly about a transversely extending axle relative to the base member. The sole holder in the position of use is held thereat by a locking spring which acts onto a locking mechanism also supported on the base member. A hand lever is pivotally secured to the base member for movement about a second transversely extending axle, and through compression of the locking spring overcomes the spring loading of the locking mechanism. Thus, the sole holder can be swung upwardly force-free. The locking mechanism includes a first locking rocker arm which is pivotally supported for movement about the second axle and engages the sole holder and a second locking spring. The second locking rocker arm is also supported on the base member. The hand lever engages the first locking rocker arm so that upon a manual manipulation thereof, the locking spring will be compressed until the sole holder can be freely swung upwardly.
