摘要:
A ski and ski-binding combination. The ski has several holes for receiving therein fastening screws for the selective fastening of ski-binding elements arranged in the ski in the binding-installation area. The holes are covered, however, are marked to the outside by markings. The arrangement of holes for the ski-binding elements is adjusted to the length of the ski and chosen such that the ski bindings are suited to receive only a limited number of successive ski-boot sizes.

A cross country ski has a bending resistance which is changeable with the help of at least one bending beam, the beam extending longitudinally of the ski and being arranged in the center of the ski. The bending beam is arranged loosely inside of the ski, symmetrically in relationship to a vertical longitudinal center plane of the ski, and is supported at its two ends on support surfaces of the body of the ski which extend approximately parallel to the running surface. In a first preferred embodiment, pressure can be applied to the beam on a side thereof which does not face the support surfaces by a pressure element which is supported on the body of the ski in the region of the upper side thereof. In a second preferred embodiment, the beam has on its side which does not face the support surfaces a pressure-transmitting member, to which a pressure toward the beam can be applied by a control mechanism.

The invention relates to a shock absorber for fastening of ski bindings to a ski (1) having an upper belt (3).Such shock absorbers are already known in the form of multi-layered strip-like inserts. A disadvantage of this known design is, since the strip-like inserts must be built in during the manufacture of the ski, an adjustment to different hole arrangements of ski binding parts.The goal of the invention is to enable an individual adjustment for shock absorbers of this type even when the ski has already been manufactured and for many different hole arrangements of ski binding parts.The set purpose is attained according to the invention by the insert (9, 10, 11) being stored in a sleeve (7), which in turn is inserted into a bore (6) of the ski (1) and is screwed into said bore (6). Each fastening screw is thereby constructed as a metal screw (12), which can with its thread be screwed to the high strength layer (11).

A ski binding comprising a release mechanism controllable voluntarily through a wireless transmission path and releases a lock of a jaw of the binding, which transmission path is controlled by a manually operable switch. To avoid an undesired release of the binding, it is provided that the switch is countersunk into an outwardly opening recess in the handle on a skipole, so that the manually operable part of a button on the switch can be manually engaged only by purposefully inserting a finger of a user's hand into the recess.
摘要:
A device for detecting the forces acting onto a ski binding or a shoe held in such a binding comprising at least one feeler emitting electrical signals in dependency from the occurring forces and an evaluating circuit processing the signals. In order to be able to calculate the state of fatigue of the skier and, if necessary, the condition of the binding, it is provided that an integrator circuit constructed as a counter is connected after the evaluating circuit, which integrator circuit is connected to an indicating device and which can be reset merely by means of a manually operable switching device. The counter can thereby count either signals of the evaluating circuit corresponding with predetermined impacts, or digital signals corresponding with impacts having an energy content, or signals which correspond with those impacts, the rising and dropping speed of which exceed a limit value.

A ski binding in which a heel part can be adjusted in the longitudinal direction relative to a guide fixed to a ski and can be actuated by hand. In order to prevent the connecting web of the opening lever disengaging from the locking plate s well as involuntary unlatching of the heel part due to external influences, the invention provides that the connecting web of the opening lever is designed in a U-shaped manner, and that the connecting web, bent in the direction of the upper side of the ski, forms protecting web which terminates flush with the guide fixed to a ski. A restoring lug assists the function of the spring, which acts on the locking piece, the restoring lug being actuable, by way of an edge of the connecting web, by pulling on the opening lever and being formed by being bent out of the locking plate.
摘要:
An apparatus for facilitating optimum adjustment of a cross-country ski, the bending resistance and/or arch of which can be adjusted, includes a sensor connected to a control circuit, and the control circuit is in turn connected to either a drive mechanism which automatically controls the adjustment of the ski or to an indicating device which visually indicates the necessary adjustment to be made manually. The control circuit monitors ski performance at a given adjustment for a predetermined interval, thereafter determines an appropriate adjustment, then monitors ski performance at the new adjustment for the predetermined interval, and so forth. A gearing mechanism powered manually or by an electric motor can be provided to effect the automatic adjustment of the ski in response to an output of the control circuit.

A front jaw for a safety binding comprising a lower part (3) of a housing, which lower part can be fastened to a ski, and an upper part (2) of a housing having at least one adjustable release spring (4) and two pivotal sole holders (14a, 14b) biassed by this release spring, with the upper part (2) of the housing being pivotal in the position of use of the front jaw about a transverse axis (Q) extending essentially normally with respect to the central longitudinal axis (L) of the front jaw, and the swivelling capability of the upper part of the housing relative to the lower part of the housing being limited by a locking piece (15, 115) having at least one stop surface (32a.sub.1, 32b.sub.1, 32a.sub.2, 32b.sub.2, 32a.sub.3, 32b.sub.3, 32a.sub.4, 32b.sub.4), which locking piece is supported horizontally movably in the lower part (3) or the upper part (2) of the housing, with this locking piece (15, 115), in the position of use of the ski binding, cooperating with a stop (29a, 29b) provided on the upper part or lower part of the housing, so that the swivelling movement of the upper part of the housing relative to the lower part of the housing is limited in this position.
摘要:
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.
摘要:
An anti-theft lock for securing a binding to a ski, in particular a binding suited for the holding of ski shoes of any desired length without longitudinal adjustment. The binding includes structure which can be locked either in its stepping-in position or in its closed position by a lock, a switch or the like to thereby prevent removal of the binding from the ski.
