摘要:
The invention relates to a ski equipped with a beam and a device intended to modify the stiffness and/or shock absorption of vibrations. The ski includes (1) at least one elongated element oriented longitudinally with respect to the ski, connected to the ski by a rigid linkage and which includes at least one free end, suited to be displaced longitudinally with respect to the ski when the ski is biased in flexion, and spaced longitudinally from the rigid linkage, and (2) a resistance device connected to the ski that cooperates with the free end in order to resist its displacement, the resistance force of the resistance device that resists the displacement of the free end decreasing between a minimum displacement position and a maximum displacement position. Such a ski maintains its stable qualities in a horizontal position and improves its pivoting and steering characteristics during tight turns.
摘要:
A ski equipped with at least one shock-absorption device adapted to absorb the vibrations of a ski having at least one flexion blade which includes a first portion fixed rigidly to the ski and a second portion connected to the ski in a longitudinally mobile manner by a shock-absorption arrangement of the viscous friction type.
摘要:
Ski having the shape of an elongated beam comprising a lower sliding face, an upper face, and two lateral edges, the upper face comprising, in its central portion, a projecting platform such that the upper face of the ski is constituted by a central upper surface projecting outward from an upper front and rear surface and positioned between these two surfaces. The central platform is extended to the front and/or to the rear by least one connection projection piece whose width is less than the width of the platform, and whose height decreases, at least in its section connecting with the upper front or rear surface.
摘要:
Assembly of the ski is effected in one preliminary step in which a mechanical resistance sub-assembly is produced, followed by a single molding step. During the preliminary step, at least one lower reinforcement piece (1), a core (2), and an upper reinforcement piece (3) are stacked together, said stacked assembly is inserted in a heat retractable casing (4), and the casing is heated to shrink it retracted. During the single molding step, the lower elements of the ski structure (11, 12, 13) are placed in the mold, the mechanical resistance sub-assembly is placed on the lower elements of the ski structure, the mold is closed, and a thermohardenable polymer is injected so as to form the protective covering (15) of the ski.
摘要:
An interface device adapted to be positioned between a ski and an assembly for retaining a boot on the ski, the device including front and rear platforms that are raised with respect to the surface defined by the upper surface of the ski. The platforms are supported by a cradle having a reduced length with respect to the volume of the platforms, each of the platforms being connected to the cradle by a bearing journal, and both platforms being connected to each other by a non-extensible connection located above the journals. The invention also relates to the combination of a retention assembly and a ski.
摘要:
The invention relates to an interface device between a boot and a ski for modifying in a dynamic manner the pressure distribution of the ski on the snow. The device includes two binding elements, a mobile sensor, a return rocking device, and an element affixed to the ski. The rocking device is arranged to transform a vertical bias exerted on the sensor into a traction bias exerted on the element affixed to the ski. In reaction, a traction bias of the same type can be transmitted towards the rear of the ski.
摘要:
A ski having a first lower assembly or base whose front end is raised to form the spatula, and a second upper assembly or stiffener whose front and rear ends are connected to the base by a flexible and/or partially rigid connection, and includes at least one support or stirrup connected to the base adapted to receive the bindings in order to maintain the boot on the ski.
摘要:
Ski comprising a lower sub-assembly providing mechanical resistance (2) and an upper cover sub-assembly (3). The lower sub-assembly (2) comprises an outer sole plate for sliding (20), lateral metal edges (21), a core (22), at least one lower reinforcement piece (23) and at least one upper reinforcement piece (24). The upper sub-assembly (3) comprises at least one thin, flexible outer membrane (30) and a filling material (31) made of deformable, elastic plastic foam interposed over at least a portion of the length of the ski between the membrane (30) and the upper reinforcement piece (24).
摘要:
Device for damping ski vibrations constituted by at least one flexible strip rigidly attached to the ski and at least one flexible connection piece, the rigid attachment being spaced longitudinally apart from the flexible connection piece.
摘要:
A ski having a sole equipped with discontinuous serrations including a central flat gliding zone and on one side, at least, a lateral curved gliding zone bordering the central zone. The surface of the rear portion at least, of the central zone between the rear contact line and the center line of the boot of the ski is equipped with a pronounced structuring such that the measured values of the significant roughness parameters Rtm and Rku are greater than the values measured on the surface of the lateral curved gliding zone. The invention is more specifically related to an alpine ski whose ability to pivot and to glide are thus improved.
