Abstract: A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame of the tricycle is configured to rotatably support the rear wheels and configured to support the head tube at a distance from the rear wheels such that a distance between the head tube and rear wheels need not necessarily be changed even when the front wheel axis location is changed from one mode to another.

Abstract: The present invention relates to a spring cartridge for a ski binding, wherein the ski binding has a rotatable front binding part for attachment of a ski boot, and is in particular a telemark ski binding. In the binding the spring cartridge provides tension to a biasing cable which biases the rotatable front binding part, so as to rotate the front binding part so that an attached ski boot would be brought into contact with the ski to which the ski binding is attached. The spring cartridge comprises an extended hollow housing open at both ends, a compression spring held within the extended hollow housing and a pressure stub held partly within the compression spring. The pressure stub is structured with an extended portion having a cross dimension smaller than the interior size of the compression spring and a head having a larger size than the interior size of the compression spring.

Abstract: An apparatus for tensioning the cable or bail of a ski-touring binding, a tensioning lever for such apparatus, and a replacement component for the lever are provided. The apparatus provides different tension for walking and for skiing. The lever includes a handle and a pivot for rotational engagement of the lever on the cable or bail. The pivot is located between the handle and a plurality of boot heel holders. The holders are configured such that at least one holder will contact the ski boot heel at a different distance relative to the pivot than another of the holders. The replacement component is removably fixed to the lever and is configured to provide a heel holder surface and to retain a bail or cable in rotational engagement with the lever.

Abstract: The snowboard binding with a pivoting heel element and a movable instep element has, in the area stepped on by the sole of the snowboard boot, a movable tread element that is coupled both to the instep element and to the heel element such that, when the tread element is pressed down in the direction of the snowboard surface, the instep element and the heel element are simultaneously and synchronously forcibly moved into their closed position.

Abstract: A binding for snowboards has a back plate 2 at the rear of a base plate 1, and the back plate 2 is moved back and forth to vertically move side plates 3 which are provided with an ankle strap 32 and a toe strap 33.

Abstract: A cross-country ski binding, especially a hiking ski binding which includes a toe iron (10) adapted for mounting on a ski top and having cheeks (11) and sole catches (12) for accommodating and supporting the front part of the sole of a ski booth in sideways, forwards and upwards directions. A tension cable (14) is adapted to be passed about the heel of the boot and includes a tensioning mechanism (13) whereby the ski boot may be fixed to the toe iron (10) such that during cross-country skiing or ski hiking, the heel of the boot and the heel of the skier may be raised from the ski top. The tension cable (14) also co-operates with a mechanism (15) for varying the effective cable length. A portion of the tension cable (14) includes a tension spring (16, 17). A tightening lever (19) bearing against the sole of the boot is pivotally mounted on the portion (18) of the tension cable (14) which is intended to be passed about the heel of the boot.

Abstract: The heel holding device has a non-stretching tension member which is movable in every direction and constructed in the manner of a ribbon. The tension member is fastened at the ski by one end and can be fastened with its other end at a peg at the heel of the boot by means of a clamp. The tension member can be detached voluntarily by means of this clamp and can be pulled off the peg when a tensile force acts substantially in the direction of the boot sole. Two parts of a connecting piece are adjustably fastened to the tension member at a distance relative to one another. The two parts form a connecting piece which is constructed in the manner of a push button. A loop of the tension member remains in the closed state of the connecting piece, which loop leads to a lengthening of the tension member after the connecting piece is loosened when acted upon by increased tensile force, so that the boot heel can be lifted farther from the ski.

Abstract: A footloop for a windsurfing board having a deck with a top surface. The footloop is formed of a strap having opposite ends attached at the ends to the top surface of the board, including a device for attaching at least one of the ends to the deck which includes a releaseable mechanism for holding an end portion of the strap until a certain amount of force is exerted on the strap, whereupon the strap is released. The releaseable mechanism is adjustable for differing amounts of force and includes a fixed member permanently affixed to the board, a moveable member co-acting with the fixed member for holding the end portion of the strap and an adjustable device for locking the moveable member relative to the fixed member until the certain amount of force is exerted on the strap.

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 ski binding having a boot attachment member connected to a ski mounting means by tensioned cables provides two modes of angular displacement, one mode of vertical displacement, and a safety release mode. The tensioned cables lead from guide means in one member to anchor points angularly spaced around a pivot means, the anchor points and the corresponding guide means being radially spaced from the circumference of the pivot means so that each tensioned cable leads in a straight line from its anchor point to its guide means throughout a predetermined angular displacement sector of the boot attachment member with respect to the ski mounting means. In this initial angular displacement sector, the resisting counter-torque is substantially constant. Subsequently, counter-torque increases with further angular displacement until safety release of the skier's boot from the boot attachment member occurs.

Abstract: A safety ski binding which includes a cable interconnecting a ski boot or plate attached to a ski boot with the ski. A restoring spring is provided which forces the cable toward a position holding the ski boot in an in-use skiing position on the ski, while permitting relative movement of the boot and ski and consequent extension of the cable. To prevent serious injuries in the case of full extension of the cable, the cable is disconnected, thereby fully separating the ski and boot. In preferred embodiments, a ski brake is provided to brake the separated ski.
