Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a ski boot tightening device with a device that allows adjustment of the tightening tension.

One of the most widely used ski shoe tightening devices
One is mainly a plate-like member having a plurality of recesses having the same shape, the same size, and parallel to each other and each having a hook-shaped cross section; It comprises a metal ring of approximately rectangular cross section which is connected on the side with a tensioning device. Said metal ring can be replaced by a T-shaped member which removably engages with a recess of hook-shaped cross section which is approximately a multiple of the recess provided to cooperate with the ring. Tensioning devices typically have a generally plate-like seat to which a secondary lever is articulated, and one end of which is articulated at a point of resistance on said lever and the other end of which is a ring or T. It is connected to the ring or T-shaped member by a tie connected to the shaped member.

Although rough adjustment of the tightening tension is possible by interlocking rings or T-shaped members with different hook-shaped recesses, fine adjustment of this tension requires adjustment of the length of the tie. For this reason, ties are usually constructed from a pair of members connected by screws and nuts.

Although such previously known ski boot tightening devices have several advantages, they also include structural and usage disadvantages.

For example, the industrial manufacture of two screw threads, particularly nuts, that mesh well is relatively complex. Additionally, the components of such devices are typically made of plastic materials that are difficult to thread due to poor mechanical properties. Therefore, a metal material must be inserted into the threaded portion, which also makes machining difficult and therefore increases costs. Furthermore, such devices have the disadvantage that, under normal conditions of use, they are rather difficult to operate, since they are often handled by hands wearing thick gloves in cold snow. In fact, it may be necessary to tighten and loosen the screws on the moving part several times in order to adjust the desired tension.

The main purpose of this invention is to eliminate these drawbacks. The purpose is to provide a rod-like member of the type driven by a tensioning device through a tie part, said tie part comprising a segment which is flattened on one side along the generatrix and has a plurality of grooves. , extending along the line of motion of the tie and having a diameter and depth corresponding to the diameter and length of the grooved segment of the bar member.
a generally plate-shaped body having a hole; a second hole disposed in the body and extending transversely to the first hole and intersecting the first hole; , a pin fitted into the second hole and having a diameter smaller than the width of the groove; will be achieved.

Next, embodiments of this invention will be described with reference to the accompanying drawings. The ski boot tensioning device according to the invention comprises a catch, for example a T-shaped element 1, of the conventional type, and a tensioning device 2, also of the conventional type, the T-shaped element and the tensioning device 2 being of the same type. , are tied together by a tie part 3 whose length can be adjusted.
In particular, the element is constituted by a metal bar 4 which is inserted into one of a plurality of recesses 5 provided in a fixing element 6 in a manner known in the art, and a metal rod 7 attached to this bar 4. ing. The tension device 2
is equipped with a fixing member 8, and this fixing member 8
A secondary lever 9 is articulated to it. The tie 3 is composed of a rod-shaped member 10 and a main body portion 11, and the rod-shaped member 10 has a tip portion 12 connected to a hook portion, and a cylindrical segment whose one side is flattened along the generatrix. 13. The cylindrical segment 13 has a plurality of generally annular grooves 14 having a predetermined width and depth. The substantially plate-shaped body 11 has on one side articulated the lever 9 of the tensioning device 2 and on the other side a first hole 15 with an axis in the same direction as the line of motion of the tie 3. and this first hole 15
and a second hole 16 that intersects with the second hole 16 . The axis of the second hole 16 is not located in the same plane as the axis of the first hole 15, but extends transversely to the axis of the first hole 15. The second hole 16 has a second
A pin 17, which engages in the groove 14 of the segment 13 of the rod-shaped member 10 in the position of use shown in the figures and FIG. 3, is inserted longitudinally and fixed in a suitable manner.

The operating principle of the device according to this invention is as follows.

In its normal position of use, when the boot is tightened, the pin 17 engages in one of the grooves 14 of the segment 13 of the bar 10, as shown in FIGS. 2 and 3. Thus, in this position, the rod-shaped member 10 is connected to the main body 11.
is combined with If you wish to finely adjust the tightening tension, remove the T-shaped member from the recess 5 and
The rod-shaped member 10 is removed from the pin 17 by rotating the character-shaped member and the rod-shaped member 10 integrally formed therewith by 180° inside the hole 15 .

As shown in FIGS. 4 and 5, in this position, the rod-shaped member 10 can slide vertically within the hole 15, so that it can be easily moved to a desired position. After the bar member 10 has been moved to the desired position, the T-shaped member is operated to rotate the bar member 10 again by 180° to reengage the pin 17 with the groove corresponding to the new adjustment position. The boot can then be tightened again by operating the tensioning device 2 in a manner known from the prior art.

As can be easily seen, fine adjustment of the tightness with the device of this invention is much easier and faster than with previously known screw-and-nut devices, but accuracy and reliability are compromised. In this respect, it is also comparable to conventionally known devices.

Also, the structure of the device according to this invention is much simpler than previously known devices. That is, structurally, the rod-like member 10 is less complex than a screw, and the pin 17 is much simpler than a nut and is easier to install than a nut.

In the above embodiment, the rod-shaped member 10 has a hole 15
However, in order to avoid this, it is sufficient to provide the rod-shaped member 10 with a suitable stopper.

It goes without saying that the scope of the invention is not limited to the embodiments described above, but also includes all other possible embodiments.
