Description

Description: TECHNICAL FIELD The present invention relates to a clamping device, especially for sports shoes.

BACKGROUND OF THE INVENTION Conventional shoes, such as those used for trekking or mountaineering on rocks or ice, have a shell or upper with two flaps or tongues. Straps or cables must usually be used to tighten the flaps or tongues.

Such tightening elements are usually guided by adjacent matching hooks or rings associated near the edge of the flap. This allows the cable or string to traverse the upper body or shell multiple times.

The ends of the cords or cables are then clamped, for example by tying a knot, or in any case by employing conventional adapted levers.

The use of guide elements constructed of hooks or rings as described above presents several drawbacks. That is, multiple passes of the string across the upper body or shell
Substantial friction is created and therefore, when tension is applied to the ends of the string, optimal tension cannot be applied to each portion of the string.

In either case, to tighten the loose ends, the user must pull on portions of the straps that are placed across the upper.

This work must be done at extremely low temperatures where the string becomes hard,
In addition, workers must wear gloves in any case.
Therefore, the above method has drawbacks because it makes the work more difficult.

DISCLOSURE OF THE INVENTION The object of the present invention is to provide a device for optimally and easily tightening a lace or cable in a shoe with an upper or shell having two flaps or tongues to be tightened, It is an object of the present invention to overcome the drawbacks of the prior art and solve the above technical problems.

Within the scope of the above objectives, an important objective is to provide a device capable of achieving the above clamping fixation even at cryogenic temperatures and when the user is wearing gloves.

Another important object is to provide a device that allows the clamping to be achieved by the user simply grasping the end of the cord or cable or the adaptive lever associated with said end.

Another object is to provide a device that is simple in structure and inexpensive to manufacture.

The above and other objects which will become apparent from the description hereinafter are a clamping device, especially for sports shoes, comprising an upper or shell with two flaps or tongues to be clamped by a strap or cable. achieved by The clamping device is characterized in that it comprises a plurality of pulley members associated with the upper body or shell for guiding the string or cable, the pulley members being rotatable about two axes substantially perpendicular to each other. do.

BEST MODE FOR CARRYING OUT THE INVENTION Referring to FIGS. The upper body or shell has two flaps or tongues indicated at 203 to be tightened by a string or cable indicated at 204 .

Reference number 205 indicates a clamping device with a plurality of pulley members 206 . Preferably, the clamping devices are in pairs and are arranged substantially opposite each other with respect to the pair of flaps or tangs 203 . Pulley member 206 consists of a generally C-shaped plate 207 between wings 208a and 208b. Pulley 210 is, for example, by first pivot 209
It is rotatably associated near the free end of plate 207 . In sports shoe 201, pulley member 206
In one or more of the open ends with which the pulleys 210 are associated are oriented toward the central longitudinal axis of the tongue 203 . On the other hand, other pulley members have their open ends directed toward the side edges of the tongue.

By arranging several pulley members 206 in this way,
Different paths are provided for the ties or cables 204 . This allows for a good distribution of the clamping force, and in addition ensures that the tightness of the cord or cable can be further improved.

A base 211 of each plate 207 is formed with a sleeve 212 by bending. The sleeve 212 is arranged along a first axis 213 that is generally perpendicular to the axis of the first pivot 209 .

The clamping device also comprises means for connection to the flap or upper body or shell. This means consists of a metal wire 214 formed in a generally triangular shape. The base of this triangle is a sleeve so that it can rotate.
212. The vertex 215 is shaped to form a small hole 216 .

The small hole 216 is substantially perpendicular to the first axis 213 and the first
has a second axis 217 which is substantially parallel to the axis of the pivot 209; Associated with the eyelet 216 is a second pivot 218 for connection to the flap or upper body or shell.

The invention is used as follows. Once a clamping device, preferably a pair of clamping devices, is transversely associated with respect to the shell or upper body, the cords and/or cables are routed to the wings 208 of each pulley member 206.
It is inserted between a and 208b and placed in the groove of pulley 210 .

Friction is greatly reduced by the pulleys and forces can be optimally distributed when the string or cable is pulled so that the user simply pulls on the loose end of the cable or string to pull the cable. Or you can apply optimal traction to the string.

Since each device conforms to the shape of the shoe and spontaneously centers itself with respect to the forces involved, the user simply pulls on the loose end of the cable or lace to pull the cable. Or you can apply optimal traction to the string. The reason for this is that the first axial bore
The plate 207 oscillates about 213 and also the second axis 21
This is because the small hole 216 oscillates with respect to 7.

Friction can therefore be significantly reduced, tightening the straps or cables while optimizing force distribution.

Thus, it is evident that the present invention achieves the intended objects. It is also applicable to sports shoes, allowing the laces or cables to be tightened and therefore in a very quick and easy way even if the shoe tightening has to be done under the worst weather conditions. It has now become apparent that there has been provided a clamping device capable of clamping a .

It is also easy to loosen. This is because once the end of the string or the end of the cable is loosened, the traction element can be loosened by normal pressure such as applied from the top of the foot to the shell or upper while the traction element is slidable on the pulley. is.

Depending on the shape of the foot, the locking force can be further enhanced, as the pulley members can be placed at desired positions on the shell or upper body and each pulley member can be oriented by itself in response to the force applied to the cable or string. Can be increased. this is,
This is because the individual elements can themselves be oriented along the two axes 213 and 217 .

4 and 5 show clamping device 305. FIG. This device 305 is constituted by a base 319 and has means for connecting to a flap or upper body or shell.
Protruding from each side of base 319 are two wings 320a and 320b. A second pivot 321 is freely associated between the wings and is positionable within sleeve 312 of plate 307 . This plate is therefore rockable.

Plate 319 also includes a first end 322 partially disposed under plate 307 and a pair of wings 320a and 320b.
and a second end 323 projecting beyond. A through hole 324 is formed in the plate 319 . This through hole 324
a second axis 317 substantially perpendicular to the first axis 313 and substantially parallel to the axis of the first pivot 309;
have.

It is of course possible to optimize the number of pulley members, the specific configuration, dimensions and materials of the pulley members according to specific requirements.

Of course, the configuration of the shell or upper body pulley member 6
It can be the most suitable one according to your specific requirements. Each of the pulley members may be arranged with its open end facing toward the central longitudinal axis of the shoe.
