Abstract: A cross country ski binding has a support element attachable directly to a ski for engaging a forwardly extending boot sole extension, and is also provided with latching mechanism for latching the sole extension to the supporting element, under imposition of spring forces. The cross country ski binding may include spring biased detent members engageable into detent provisions provided directly on the boot sole extension, such that the forward part of the ski boot is automatically locked in position upon insertion of the boot sole extension into the support element. Preferred embodiments of the invention include those accommodating an axial movement of the boot sole extension into the support element and latching mechanism, as well as embodiments wherein the boot sole extension is placed downwardly over a pivot pin forming part of the holding mechanism. Also, certain embodiments of the invention include additional locking levers for locking the latching mechanism in a latched position.

Abstract: A uni-wheel skate has a circular wheel which has a rim arranged to rotate about a frame having a generally tilted axis so that the rim rotates in a plane which is generally tilted relative to the vertical. The frame has satellite rollers rotatably attached to the frame and engaging the rim so as to permit the rim to rotate about the frame. A foot support is pivotally carried by the frame and receives the rider's foot for transmission of the rider's body load to and through the frame to the wheel. A separate support is associated with the frame to be rotatable relative to the frame to be engaged with the rider's leg to maintain stability. The pivotable foot support may be provided with brake pads for engaging the rim.

Abstract: A structure for securing one end of a safety strap to a ski or to a component fixedly mounted on the ski. The other end of the safety strap is presumed to be secured to the skier by any conventional means. The structure by which the safety strap is secured to the ski structure enables the strap to hold the ski to the skier should the ski become disconnected from the skier while travelling on a chairlift or at slow speeds. However, this same structure will facilitate a release of the strap from engagement with the ski structure should the ski be pulled away from the skier with a sufficient magnitude of force, such as will occur during falls at high speeds. The thereafter released ski will be stopped by, for example, a ski brake mechanism mounted on the ski.

Abstract: A safety ski binding includes an end piece engageable with a ski boot and horizontally pivotable on a body rotatably mounted on a pivot member carried on the surface of a ski for vertical pivotability with respect to the ski. The vertical pivot member includes two diametrically opposed cam faces movable in the longitudinal direction of the ski, each of the cam faces being engaged by a separate piston while being urged by a common spring. The end piece is adapted to move one of the two pistons away from the corresponding cam surface on vertical movement of the end piece. A modified embodiment of the invention utilizes a single piston and the spring controls the release of the ski boot under both side torsion stresses and vertical movements of the ski boot end associated with the binding when they exceed predetermined and adjustable limit values.

Abstract: A restraining device for removable components of vehicles, such as the battery unit (26) of an electrically powered lift truck. The vehicle has an enclosure frame (14) having opposite sides (16,20) each of which has an aperture (30,28) through which passes in a longitudinally slidable fashion a restraining bar (34) positionable to a locked position preventing dislocation of the removable component (26). The restraining bar (34) may be fixed against longitudinal movement by affixing it to the enclosure frame (14) with a locking means (42). If the restraining bar (34) is not in its locked position a pivotably positional cover (52) overlying both the removable component (26) and the restraining bar (34) cannot be placed in an operating position owing to contact between the restraining bar (34) and a downwardly extending edge portion (58) of the cover (52).

Abstract: A roller ski training device which effectively simulates weighting, unweighting, and edging techniques of the downhill parallel snow skiing. The device includes a support frame, a pair of parallel elongated foot plates pivotally carried in side by side relation by said support frame, and rollers flexibly coupled to the underside of the support frame whereby the shifting of weight by a user to the foot plate on one side of the device tends to cause the device to turn in the direction of the other side. The flexible roller coupling further permits tilting of the frame, with the resultant raising and lowering of the foot plates, in response to the shifting of weight from one foot plate to the other. Parallel linkage is connected to the underside of the foot plates to synchronize pivotal and vertical positioning of the foot plates such as to maintain them in parallel planes at all times.

In another embodiment, a platform is stationarily mounted ahead of the toepiece of the downhill binding, with a separate heel support secured to the ski between the downhill toepiece and heelpiece.

Abstract: A device for the control of the traveling speed of a motor vehicle with an electrical controller applied by an actual speed signal and a desired speed signal, an output stage which contains a servo-motor being in operative connection with an element, preferably the throttle valve, which element influences the ratio of the fuel-air mixture that is supplied to the vehicle engine, and the output stage being electrically connected to a first switch which is coupled to the foot brake to switch the output stage into an inoperative condition if the foot brake is actuated. An additional switch which is actuatable by output stage, which switches are disposed in an electrical control circuit (which circuit influences the rotational speed of the engine) are embodied such that if the brake is actuated and if the output stage is outside the idling position the control circuit is controlled in the sense of a reduction of the rotational speed.

Abstract: A ski brake having at least one braking leg, which is pivotal by a force applied by a ski boot or by a sole plate to a pedal about an axle, which extends substantially at a right angle with respect to the longitudinal axis of the ski in a mounting member which is secured to the ski, from a braking position against a spring force into a retracted position. The braking leg is pivotal about a swivel shaft which extends in longitudinal direction of the ski when the ski brake is in the retracted position. The braking leg has a sliding segment thereon which slidingly engages during the swing of the ski brake from the retracted position into the braking position a ski binding part to thereby positively effect a driving of the braking mandrel about the axis of the swivel shaft laterally outwardly beyond the lateral edges of the ski.
