The first fastening axis forms a first angle ?1 with the first longitudinal axis, the second fastening axis forms a second angle ?2 with the second longitudinal axis, the angle ?1 and angle ?2 being oriented in the same direction, and at least one of the angles ?1 and ?2 being non-zero.

Abstract: The invention is directed to a rim such as a rim for a cycle. The rim includes a circularly extending hollow box-shaped element, in the form of a radial profile of revolution about a transverse axis, with two end surfaces of such element being joined end-to-end at a junction and affixed via a sleeve that is positioned within the hollow box-shaped element, on each side of the junction. The sleeve includes a pair of bearing portions, which exert an internal force inside and against the walls of the hollow box-shaped element, such force being generated by a relative spacing apart of the bearing portions via a spreading device, such as at least one spacing member. The spacing member can be a wedging member or a screw, configured and arranged in association with the bearing portions so as to direct the bearing forces along an essentially transverse direction toward the side walls of the rim. The invention is also directed to a wheel having such a rim, as well as to a method of manufacturing such rim and wheel.

Abstract: A roller skate including a frame provided to receive a plurality of wheels; a sole adapted to support the user's shod foot; a heel stiffener; a foot retaining arrangement, capable of being in an open state, which enables insertion of the user's foot and, in a closed state, enables adjustment of the foot retaining arrangement around the user's foot, the foot retaining arrangement including: a forefoot anchoring, an instep anchoring, the forefoot and instep anchorings each having a pivot zone about which the foot retaining arrangement pivots when it is moved between the open and closed states; a forefoot fastening device, an instep fastening device adapted to keep the retaining arrangement in the closed state; and an adjustment mechanism enabling adjustment of the retaining arrangement to the morphology of the user's foot.

Abstract: A gliding or rolling board having a length measured along a longitudinal direction between a first end and a second end, a width measured along a transverse direction between a first edge and a second edge, as well as a height measured between a bottom and a top, the board including a core that extends along a substantial surface. The board includes a lower reinforcement located beneath the core and an upper reinforcement located above the core, the lower reinforcement including a first layer of natural fibers, the upper reinforcement including a first layer of natural fibers.

Abstract: The invention provides for a sandwich-type layered structure including at least one first core layer made of cellular material, a first reinforcing layer connected to a first surface of the first core layer, and a second reinforcing layer on the side connected to the second surface of the core layer, the layered structure including, between the first core layer and the first reinforcing layer, at least one compressed foam layer connected to these two layers.

Abstract: The invention proposes a gliding board including a sandwich-type layered structure comprising at least one first core layer (12) made of alveolar material, a first reinforcing layer (14) connected to a first surface of the first core layer, and a second reinforcing layer (14) connected to the second surface of the core layer, characterized in that the layered structure is reinforced at least locally by at least one compressed foam layer (16) that is arranged between the first core layer (12) and the first reinforcing layer (14), and is connected to these two layers.

Abstract: The invention relates to a buckle for fastening a sports boot and to a sports boot including such buckle. The buckle includes a baseplate, a lever connected to the baseplate by a first transverse articulation about an articulation axis, the lever having a gripping portion, a connecting rod articulated to the lever by a second transverse articulation about a second articulation axis, a loop mounted at the other end of the connection rod.

The body is formed by a sheet of material, and the sheet is folded along folding lines that are parallel to each of the articulation axes to form the tubes for guiding the articulation axles.

Abstract: A safety binding device for binding a boot on an alpine ski including a releasable retaining mechanism of the mechanical, hydraulic, viscoelastic type, which actuate a release as a function of the forces to which the boot is subjected and as a function of the duration ?t of the application of such forces. The release action occurs as soon as the magnitude of the force is greater than an actual release threshold, Sr, which is dependent upon the duration ?t of the application of force, such that if duration is greater than one second, the actual release threshold is between 50% and 75% of the theoretical release threshold, St, whereby: ?t>1 s; 0.75×St?Sr(?t)?0.5×St, with the theoretical release threshold St being determined as a function of the skier's parameters in conformance with ISO standards.
