摘要:
A ski boot comprising: a rigid shell which is shaped so as to accommodate the foot of the user, and has a lower part structured to be able to couple to a ski binding device; a rigid cuff which is shaped so as to enclose the lower part of the leg of the user, and is pivotally joined to the shell so as to be able to swing about a rotation axis substantially perpendicular to the midplane of the boot; and a cuff locking device which is located on the cuff and is selectively adapted to rigidly connect the cuff to the shell to prevent the cuff from swinging on the shell; the cuff locking device, in turn, comprising a movable arm which is pivotally joined to the cuff so as to be able to rotate to and from a locking position in which the movable arm extends downwards and arranges its distal end in abutment on an anchorage structure present on said shell, and an elastic assembly which is adapted to bring and elastically retain the movable arm in the locking position, and which basically consists of a telescopic stem that lies substantially on the rotation plane of the movable arm and is interposed between the movable arm and a fixed point on the cuff, and of an elastic opposing member that is fitted on the telescopic stem, and acts on the telescopic stem so as to bring and elastically maintain the telescopic stem in a maximum extension configuration.

The inventive skate consists of an upper that is designed to accept the foot of the user. Other portions of the upper are preferably constructed using a semi-rigid material, such as fiberglass, nylon, plastic, etc. These semi-rigid portions of the upper decrease the flexibility of the upper in certain sections, thus increasing performance. The inventive skate also includes a blade chassis. The chassis includes a lower portion that is adapted to hold the skate's blade and an upper portion that is adapted to cover a portion of the upper. The inventive skate is configured so that the center of gravity of the skater is disposed generally centrally along the length of the skate chassis. This skate configuration is generally referred to as neutral pitch.

The invention relates to a shell part of sports shoe and a method for producing such a shell part based on joining together several components made preferably of different materials in one or more injection molding processes. The method comprises: the production of at least one three-dimensional stable shoe reinforcing part, the application of a filler material on the inner side of the shoe reinforcing part; the positioning of the shoe reinforcing part on a last; and the at least partial overmolding of the shoe reinforcing part with plastic. The method enables the simple and easily controllable production of a shell part with very high rigidity or stability at least in specific areas and at the same time also ensures the workability or adjustability of the shell part during the production and afterwards.
摘要:
The present invention is a retrofit appliqué kit for use with a sport skate and which includes a plurality of reinforcing articles, each exhibiting the features of flexibility and rigidity, and which are secured to exterior locations associated with the sport skate in order to provide localized protection and impact resistance. In one embodiment, the reinforced appliqués each exhibit an upper flexible rubber layer and a second rigid metal or aramid fiber based composite exhibiting a carbon backbone. In a further embodiment, a plurality of Keviar impregnated mat constructed reinforcing attachments are secured along the sides and rear of each hockey skate. A Kevlar mat tongue is securely fastened in place over a laced skate, by looping the straps around the underside of the skate boot through an aperture configured between the boot and the blade portion.
摘要:
An article of footwear comprises a shell (10) and preferably also a leg piece (20), and features, at least at some portions thereof that do not include the sole (15), a composite structure formed of two layers (30, 40; 30A, 40A) that are made of preferably synthetic materials having different mechanical properties. At least the interfacing surface (34, 34A) of the layer (30) made of mechanically stronger materials is provided with protruding elements (36) that remain inseparably adhering to the interfacing surface (42, 42A) of the other layer (40).
摘要:
Sports boot subassembly of the shell or collar type, which comprises at least two parts, each comprising a flexible plastics material injection-overmolded over a very stiff material partially embedded in the flexible plastics material, and wherein the at least two parts comprise an assembly surface for joining them together.
摘要:
A reinforcement for a boot, in particular a sports boot, more particularly a cross-country ski boot. The boot reinforcement makes it possible to improve the torsional stiffness, efficiency, durability, lightness, cost, foot protection, and industrial workability. To achieve this goal, the boot reinforcement according to the invention includes a front zone A from the front end up to the beginning of the plantar arch, a median zone B corresponding to the plantar arch, a rear zone C. The reinforcement includes, at least in the zones B and C, at least one “sandwich” structure constituted by at least one core inserted between at least two layers, and, in the zone A, it is flexible in a substantially longitudinal direction and torsionally stiff. The layers of the sandwich structure are made of composite, carbon fibers/polymeric resin, whereas the core of this sandwich structure is made of synthetic foam, wood or honeycomb. Each zone A, B, C has a longitudinal flexural strength RfA, RfB, RfC, such that RfA
摘要:
Reinforcement element made of a composite material constituted of a layer of inextensible textile material and a layer of polymeric material assembled to the layer of textile material during a molding or vulcanizing step. The textile material is a woven or mesh material, and the textile material is a polyester, polyamide, polypropylene or glass fiber based material. The polymeric material can be a thermosetting material, such as rubber or silicone, or an injected thermoplastic, such as polyurethane, polyvinyl chloride, or polypropylene. Advantageously, the polymeric material is at least partially transparent. The composite material can be incorporated in a boot or a binding, such as a snowboard binding, in the form of a tightening strap. The invention also relates to a method of manufacturing such reinforcement element.
摘要:
A ski boot having a rigid shell made of a plastic material, in which an inner comfort element is inserted, the rigid shell including a collar fixed on a shell base. The boot has a softening structure located on the outer wall of the boot and which includes a plurality of recesses provided in the rigid shell. The recesses are provided in the ankle joint zone, in the lower portion of the outer wall of the shell base, and on the outer wall of the collar.
摘要:
The sports boot has, on the one hand a first part (1) in a first material and a second part (17) superposed on said first part and in a second material, and, on the other hand, reinforcement means (10, 11, 12, 13). The reinforcement means are at least partly formed by at least one frame (13) in synthetic material reinforced with mineral or synthetic fibers and positioned at least partially between said parts.
