Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a closure device, and more particularly to a closure device for use in a ski boot comprising a front lumbar skin and a rear lumbar skin connected to an outer skin and having a pivot lever. .

BACKGROUND OF THE INVENTION Several devices are currently known for closing the abdominal skin, generally consisting of cables, the ends of which are connected to the sides of the anterior lumbar skin, and the cables are thus It is connected to a suitable vertical lever connected to the posterior lumbar skin.

Such known devices have some drawbacks, among them:
The main drawback is that the working length of the cable is generally insufficient to open the lever and completely release the g-hide, and this makes it difficult to insert the foot into the shoe.

As a solution to some of these drawbacks, there is a temple patent application No. 8219676 dated November 24, 1882, which discloses a leather closure device that includes a leather strap that holds the front waist skin, and a leather strap that holds the front waist skin. It emanates from a row of holes along two parallel axes above.

A two-piece cable is inserted into the hole and wound over the longitudinal projection on the rear waist skin to engage the vertical lever.

A modified embodiment is also illustrated in which two boons are used in place of the protrusions and the lower pulley is adjustable.

However, this known device also has disadvantages, namely that it is structurally complex and bulky.

The reason for this is that the fixed protruding guide occupies a large part of the rear lumbar skin and the cable arrangement is also quite complex.

Temple Patent Application No. 8508207, filed May 31, 1985 and published as No. 2582486, discloses an apparatus for tensioning a flexible part for joining two parts, the apparatus It is also particularly useful in closing the belly of ski boots. The flexible connecting part passes into a first movable guiding part, which is supported by a pivoting coupling lever for tensioning to form a first loop (annular form), thus connecting the second fixed Pass around the guide part and
form a loop. This flexible connecting part and the two guide parts are constructed equivalently to a pulley.

The disadvantage of this device is that most of the possible implementations can only be provided by using a thong;
This is because the radius of the loop is too small.

Furthermore, the pivot axis of the lever must be provided at a considerable distance from the shoe surface in order to maintain the lever in the closed position.

Therefore, from the outside, it is difficult to insert the lever into the shoe, and the lever is anyway large.

The use of a thong as a flexible connecting part remains a further problem, as in the solution described, the stretching action of the thong during the first lever opening phase is also awkward and does not affect the foot. This is because the raw hide is further tightened.

Therefore, this device has a structure that is not easy to operate.

U.S. Pat. No. 4,691,454 discloses a ski boot closure device which uses a lever device to operate two cables. This lever device has a longer cable than conventional lever devices, and has a very complex and heavy structure.

Finally, in the known lever for closing the skin of a ski boot, rotating said lever approximately 180@ requires setting up a cable of a certain length, the length of which is determined by the biport of the lever. It has been found to be equal to twice the distance between the coupling axis and the connection point of the cable on the lever.

It has furthermore been found that in the initial part of the rotational movement carried out by known levers of this type, there is no cable tensioning effect and nothing is carried out at this stage.

OBJECT OF THE INVENTION The aim of the invention is therefore to eliminate the above-mentioned drawbacks of the known types, and for this purpose provides a device which
Appropriately close and tighten the leather of the ski boots that you wear from the back.
At the same time, the leather is opened sufficiently to allow the foot to be easily inserted into the shoe.

One important object is included within the scope of the above aims, and that is to provide a device suitable for closing and opening the hides by simple and rapid actions on the skier's foot. The goal is to provide the following.

Another important objective is to provide a device that is simple and safe in use as well as reliable in construction.

Another object is to provide a device suitable for employing an elongated section in the tensioner with respect to known levers.

A very important objective is to provide a device which, in addition to the improved mechanical properties mentioned above, has improved cosmetic appearance as a shoe.

(Means for Solving the Problems) The above-mentioned aims and objectives, as well as other aims and objectives that will become clear later, are achieved by a single closing device, and this closing device is particularly suitable for skis. for a shoe, the shoe having a front ventral skin and a posterior waist skin connected to the outer skin, the shoe further having a lever pivotally connected to the rear waist skin, comprising at least one tensioner; a first end of the tensioner is connected to a part, which part moves relative to the pivot axis of the lever;
The second end of the tensioning device is also connected to a part, which part is fixed to the pivot axis, and the at least one tensioning device has at least one part that can be rigidly connected to the lever. It comprises a feature having such a configuration that engages the guide member.

(Function) According to the present invention, the leather of the ski boot, which is worn from the rear, is appropriately closed and tightened, and at the same time, the leather is sufficiently opened to allow the foot to be easily inserted into the shoe.

Embodiment This closure device 1 has a lever 9 pivotally connected to the rear waist of the boot in a pivot axis IO, two cables 6, 7 each connected to a slide on the lever. It has a first end connected to the anterior abdominal skin guided by 8, and a second end 14 connected to the posterior waist skin. The position of the slide is adjustable and the lever can be twice the length of the cable with respect to conventional levers.

Referring to the drawings, reference numeral 1 denotes a closure device applied to a ski boot 2, which comprises a front ventral skin 4 and a rear waist skin articulated to the outer skin 2 in a manner known per se. It consists of 5.

The device comprises a first cable 6 guided by a guide member constituted by a slide 8 acting along a vertical lever 9.
and a second cable 7. The vertical lever 9 is pivotally coupled to the rear side of the rear evaporator 4 at a pivoting horizontal axis 10 .

Said slide 8 is moved along the lever by means of a screw 11 pivoted at its free end in the generally vertical solid axis of the vertical lever 9 .

A pushbutton 12 is connected to one end of the screw for actuation by the user, whereby the stem of said pushbutton is connected to a complementary threaded seat provided on said slide. interact with each other.

The first and second cables have their first terminals 13
is connected to an actuating part which, during closure, moves relative to the pivoting axis lO of the vertical lever 9. Said actuating part is advantageously formed on the outer side of the front layer 4. These cables are therefore provided on the sides of the anterior and posterior lumbar skins and are guided in guiding parts provided on the posterior lumbar skin (only the guiding part 17 is shown in the figure).

The first and second cables are thus arranged on the sides of the vertical lever 9 such that they are arranged approximately parallel to each other and then successively in the longitudinal solid axis of said lever. It is guided by a sliding body 8. The second ends 14 of each cable come together in a fixed part relative to the pivot coupling axis lO of said lever 9 during rotation of the lever. Said fixed part is provided, for example, in the back evaporator 5.

According to this embodiment, when opening the vertical lever 9, the amount of cable loosened is determined by the pivot coupling axis of the vertical lever 9 and the exit points of the first and second cables laterally to said lever. For the sum of twice the distance between
A value twice the depth of the recess 15 on the vertical lever 9 between the pivoted end in the axis IO and the point of approximately the maximum working stroke of the slide 8 towards said axis was added. This is the total value.

It is possible to lift the exit point of the cable away from the lever, thus lowering the transmission point on the rear hip formation, while continuing to maintain the degree of opening of the hide.

Immense advantages are achieved in this way, for example, the vertical bulking of the assembly of the guide and lever on the rear hip formation is reduced.

The action of lifting the exit point of the cable from the lever arm reduces the longitudinal dimension of said lever arm, while reducing the closing force or, alternatively, the force tending to reduce the closing. to maintain the vertical dimension of the lever arm.

Finally, actuation of the lever is utilized at all stages in which rotation is imparted to this lever.

This device advantageously has a cover part 16, such as an elastic band, in the recess 15.

So far we have considered the way in which the device according to the invention is distantly related to its intended aim and purpose. In particular, FIG. 8 schematically illustrates the operation of lever 9.

In the first part of the rotation (between positions WIA and B),
The lever 9 requires twice the length of the cable, since both sections a and b of the cable vary together.

In the second part of the rotation of the lever 9 (between positions B and C), the segment a of the cable is approximately constant 2 because of one circumference α (determined by point 8 with center 10).
This is because it substantially coincides with the circumference β (which has a radius when the lever 9 is in position fiC).

Thus, section a does not substantially change its length between positions B and C, while only section a changes its length. In this way, if in the last part of the rotation the hide is closed over the foot, making it necessary to increase the effort to achieve complete closure, this in practice results in a reduction in the length of the cable used, and therefore No more effort is required.

Therefore, the lever according to the invention can use twice the length of the cable in the first part of its rotation compared to conventional levers. However, no further effort is required to secure the hide in the last part of its rotation.

The device naturally also consists of a single tensioning device, which is located at a suitable transmission device located in the region of the joint of the second terminal 14 of the embodiment with the first and second cables. , transmitted to the posterior lumbar formation.

With reference to FIGS. 5 to 7, reference numeral 101 designates a closure device according to the invention in a ski boot 102 consisting of a front skin 104 and a rear skin 105 connected to an outer skin 103.

Book binding! 101 commands from a vertical lever 106 which is pivotally connected to the rear skin 105 at a suitable protruding wing 107.

The device further includes a first lever that is extended using lever 106.
It is constituted by a first tensioning device such as cable lO8.

The $1 cable 108 uses a first pair of guides 109 that are connected to the posterior skin 105.

The terminal end of the first cable 108 arranged laterally on the posterior abdominal skin 105 is connected to a guide member consisting of a pulley 111 which is freely pivoted to the support 110 with a suitable Y-shaped support 110 interposed therebetween. , then concatenated.

The apparatus further includes at least one cable, such as second cable 112.
the second cable has two second tensioners connected at its ends to a first point 113 and a second point 114, both points being adjacent to each other when the abdominal skin is closed;
Moreover, the anterior abdominal skin 104 and the posterior stratification 1, respectively.
It is placed on 05.

This embodiment includes an axis for pivoting to 5107 of the lever 10B when opening and closing the lever 10B;
The second cable 1 has a length four times the distance between the first cable 10B and the exit point on the side of the lever 106.
Loosen or stretch 12.

Substantial benefits are further provided, for example, reduction of large vertical dimensions in the guide and lever assembly on the rear seat.

Finally, this lever works through its entire rotation.

The invention has achieved its intended aims and objectives5.
It is devised that the device makes greater use of the tensioning device than was achieved in the prior art, and that the effective action is further applied to the lever during its entire rotation.
