摘要:
The clamp is of the type which may be actuated by means of an auxiliary actuating member. It consists of two parts, namely a clip (1), whose two branches are connected via a thin part (7) and a slit housing (8) in which an actuating member (2), consisting of a pin with a diameter greater than the diameter of the housing (8) or a cam equipped with a radial arm, is accommodated. The introduction of the pin or, respectively, the rotation of the cam results in closure of the clip, causing the thin part (7) to bend resiliently.

Ski boot having an articulated shank comprising means for fixing or releasing the shank for rotation, means for adjusting the inclination of the shank and an elastic element (15), the elasticity of which is adjustable. The adjustable inclination is achieved by means of a shank in two parts, the length of which is adjustable by means of a button (12). The locking or the release for rotation is obtained by means of a sliding locking member (24) interacting with a V-shaped bolt (16) itself interacting with cut-outs (19) in a cradle fixed to the shank (2). The elasticity of the elastic element (15) is ensured by the displacement of a sliding rigid sleeve (19) around the elastic element (15), which displacement is controlled by a button (32).

The boot consists of a shell having a lower part (1), on which is articulated an upper part (2, 3) which can pivot about a substantially horizontal pivot pin (4). This pivoting is limited by an elastic device (7) mounted between the upper part (2) and the shell (1). This elastic device comprises a rigid base (8), in the extension of which is mounted a bar of elastic material (15) having the same cross-section as the base. A tubular slide (19) slides on the base and prevents the elastic material from expanding when axial pressure is exerted on the latter. The elasticity of the device therefore varies according to the position of the slide (19). A means of axial guidance prevents the elastic material (15) from bending or buckling.

The invention relates to a padding allowing an article of clothing or an accessory to be adapted closely to a part of the human body.This padding is constituted by a thermo-formable plastic foam 2 placed in a non-extensible covering 1 and making an open cavity intended to receive the part of the body, but of which the dimensions are generally smaller than this part of the body. The housing is thus formed by the reciprocal compression of the foam and of the part of the body placed in the cavity while the temperature of the foam is brought to the thermo-forming temperature.This invention can be used for adapting boots, helmets, gloves, swimming flippers, etc.

A belt conveyor which comprises two flexible elementary belts (1,2) each provided with a longitudinal reinforcement (16,17) embedded along the neutral axis of the belt, and with a number of projections and recesses which fit exactly in one another when the two belts are brought into contact along a straight section used for conveying loads. The two belts are thus interlocked and form a rigid beam (7,8) with a high flexural strength along the straight section. With each change in direction of the conveyor, the belts follow separate paths where they can readily be curved by virtue of the flexibility of each belt.

A valve device useful for obtaining a predetermined and immediate appreciable initial rate of flow of aerosol from an aerosol container and a subsequent predetermined and small continuous rate of flow. The valve device contains a standard valve, which is crimped on the aerosol container, and a unidirectional valve, located within the aerosol container and connected on one side to the standard valve, the connecting element providing a passage from the unidirectional valve to the standard valve, and on the other side to a conduit connected to a plunger tube for access to the contents of the container. Within the body of the standard valve is a movable closure element having a spring which holds the valve closed. The valve may be opened by depressing the spring with an actuator located outside the container. A closure member is provided for acting on the actuator. The closure element of the unidirectional valve is a movable diaphragm which is held closed by a second spring. During the filling of the container, the unidirectional valve is held open by the pressure applied by fluid flowing through the opened standard valve, the passage, the unidirectional valve, the conduit, the plunger tube and into the container. After the container is filled, the unidirectional valve is held closed by both the second spring and the fluid under pressure in the container. When the standard valve is opened, a second passage formed by the connection of the standard valve to the unidirectional valve and the latter to the conduit, allows for a continuous flow of fluid from the container around the closed unidirectional valve and through the standard valve to the atmosphere.

This ski boot comprises a fastening and tension device consisting of a cogged strap of which the teeth are cycloidal segments parallel to the strap plane. These teeth cooperate with drive studs carried by a rotary disc coupled to a control knob. The studs are disposed at spaced angular intervals on a circumference so that they describe cycloids corresponding to the teeth with respect to the strap.

A ski damper which can be inserted into a hole formed in the ski blade comprises a pair of housing portions which can be joined together from opposite sides of the blade to define a receptacle in which a disk is shiftable between a pair of foam rings. The disk is composed of a material having a specific gravity greater than 10 and has a thickness/diameter ratio between 1/3 and 1/30 and damps primarily vibrations in the frequency range between 100 and 200 Hz.

A tennis racket comprises dynamic weights (6) distributed symmetrically relative to the longitudinal axis of the racket between the throat and the transverse axis of the head and suspended by arcuate straps (7) glued to the racket frame (2), the weights being displaceable in a direction perpendicular to the plane of the stringed area (3). The combination of weights and straps is adapted for having an intrinsic vibration frequency about 1.4 to 2 times the fundamental vibration frequency of the racket, such that when the weights are vibrated at their intrinsic frequency (by a ball striking the racket), the vibration of the racket is damped by energy transfer to the weights, and yet energy is also returned to the racket as a reaction in the direction of the ball's flight before the ball leaves the racket. The angular stability of the racket is improved over either fixed weights or dynamic weights having frequencies outside the critical range.

The device comprises a base (10) on which is articulated a tension lever (9) acting on cables (6, 7). These cables are attached to a member (16) movable between two positions, namely a tightening position and a relaxation position, and mounted for sliding on the tensioning lever (9). Said movable member is displaceable by means of an auxiliary lever (11) mounted on the tensioning lever (9).
