摘要:
Interface device between a ski and front and rear bindings (3, 4), designed to hold in place the ends of a boot on the ski. The device comprises a longilinear plate (15), each end of which is fastened to the ski to the front and rear of the bindings. One end (16) of the plate is attached to the ski. The other end (23) of the plate is movable in relation to the ski, and linkage (24) exerts a force against a block (20) fastened to the ski, thereby pretensioning the plate (15) under traction, and, by reaction, prestressing the central portion of the upper ski surface under compression. Preferably, this pretensioning ceases beyond a determinate ski flection.

The invention relates to a device for retaining a boot on a gliding board. The device includes especially a dorsal support element and a base, the dorsal support element being journalled on the base along a substantially transverse Y-Y' axis of the device, wherein at least one braking mechanism opposes a journal movement of the dorsal support element with respect to the base along the Y-Y' axis, in at least one journal direction, and wherein a return mechanism maintains the dorsal support element substantially in contact with the lower part of the leg.
摘要:
An apparatus for retaining a snowboard shoe on a board which includes a first anchoring device for the sole of the shoe; a second anchoring device affixed to the sole; a base affixed to the board and on which are mounted an arrangement for rotationally guiding and vertically retaining the first anchoring device and a mechanism for latching the second anchoring device, the mechanism including a jaw member having a housing for receiving the second anchoring device, and a latch journalled on the jaw member. The latching mechanism includes an elastic return device biased during the displacement of one portion at least of the latching mechanism which is driven by the thrust exerted by the second anchoring device moving vertically, substantially along an arc whose radius is equivalent to the distance separating the two anchoring devices during the tilting of the shoe about the axis of rotation of the first anchoring device. The apparatus combines the ease of automatically fitting the shoe with the controlled lateral slackness necessary for the practice of the sport.
摘要:
A tension-spoke wheel including a rim, spokes, and a central hub, the exterior of the rim having a tire-receiving channel that defines a median plane, and an interior of the rim having spoke fastening zones that define a median plane for fastening the spokes, the hub having a median plane and two flanges for fastening the spokes, one of the flanges being closer to the median plane of the hub than the other, and at least the spokes fastened to the flange that is closer to the median plane of the hub lacking individual tensioning mechanisms. The spokes fastened to the flange that is closer to the hub median plane are fastened to the rim on the side of the median plane of the tire-receiving channel that is opposite the closer flange.
摘要:
An underwater diving system including at least one breathable air tank that remains at the water surface, the air tank being flexible and integrated into a bag, such as a backpack. The flexible air tank is entirely contained within the bag when the air tank is empty, and is partially deployed outside the bag when the air tank is inflated with breathable air.
摘要:
A device for retaining a snowboard boot includes a base on which the sole of the boot is adapted to rest, a turned-up heel support portion extending upwardly from the base at the rear of the device, and a dorsal support element. The dorsal support element extends upwardly from the heel support portion and is journalled on the heel support portion along an axis substantially contained in the median vertical longitudinal plane of the base. The device includes an elastic return device that elastically opposes inclination of the dorsal support element on at least one of the lateral sides of the device by rotating about the axis during rocking of the boot. The device provides binding support during lateral bending while preserving freedom of movement.
摘要:
A retention device for a boot for use on glide boards adapted to be used for snowboarding. At least one attaching device of the retention device is offset laterally with respect to the median longitudinal plane of the boot and is positioned in the vicinity of only one side of the boot, either the lateral side or the medial side of the boot.
摘要:
A boot having a flexible upper for snowboarding. The boot includes a flexible upper portion and a rigid reinforcing frame, wherein the rigid reinforcing frame includes a lower reinforcement portion surrounding the heel at least; a dorsal reinforcement portion surrounding the rear area of the lower part of the leg; both parts are connected via a narrow connecting portion that includes, on the lateral side, a stiffening arrangement that stiffens the connecting portion only during lateral tilting of the dorsal reinforcement portion on the lateral side of the boot. Because of the aforementioned construction, the boot retains its qualities of comfort and, at the same time, ensures the transmission of the essential forces by virtue of a frame that provides flexibility on the medial side of the boot and support on the lateral side of the boot.
