SI22940A - Heel grip controller - Google Patents

Abstract

Subject of the invention is a heel grip controller for adjusting the shape of the heel part of footwear which consequentially means adapting the footwear itself to the user's individual shape of the foot in the area of the heel by which the comfort and functional grip of the footwear substantially increases. The controller by way of a rotationally clamped collar (3) of the counter (1) changes the shape of the upper part of the counter (1).

Description

FITTING ADJUSTER

The object of the invention is a heel grip controller which, as an integral part of the shoe, allows the shoe foot grip to be adjusted according to the individual shape of the heel of the foot. The invention belongs to class G 01 B 11/24 of the international patent classification.

io The technical problem that the present invention solves is the design solution of such a regulator, which allows, first and foremost, a cheap implementation and secondly a simple change of the shoe's heel shape and thus the adjustment of the shoe to the user's heel, thus achieving optimum grip between the shoe and the foot, respectively. . the heel of the foot.

The current state of the art is aware of several different types of adjusters for adjusting the heel of the shoe, but the embodiments of the regulators described therein do not solve the stated technical problem in the same way.

The heel grip controller according to the invention comprises a heel 1 and a heel 3, wherein the rotary rotation of the heel 3 against the heel 1, with the proper heel shape 1 and the correct pivot point 4 of the heel 3, changes the shape of the shoe in the heel compartment and consequently regulates the grip and the respective position of the heel 3 against the heel 1 is secured by slots 5a and a pin

5b.

The invention will be explained in more detail on the basis of an embodiment and accompanying drawings, of which:

Fig. 3a, b, c, d assembly of heater 1 and chamber 3 and operation of the heel grip controller according to the invention.

The basic components of the heel adjuster according to the invention are shown in Figure 1 and Figure 2, while its operation is explained by means of Figures 3a, 3b, 3c and 3d io.

The heel grip controller according to the invention consists of heel 1 and heel 3 and is based on the principle of circular rotation of heel 3 against heel 1, which changes the shape of the shoe in the heel region with the proper shape of the heel 1 and the correct pivot point of the heel 3.

is The rear end of the repeater 1 is structurally shaped in its upper edge into a folding movable ear 2. Komat 3 with its front part is rotatably mounted or. secured in pivot 4 to abutment 1, with the back end covering the folding flexible ear 2.

While rotating the comat 3 in one direction around its pivot axis in the pivot 4, its rear part forces the folding movable ear 2 into a new position different from the starting (zero) position.

By rotating the comat 3 in the opposite direction, the flexibly moving ear 2 also returns to its initial position. shape.

The rotation of the chamber 3 is continuous in accordance with the curve determined by the point of engagement in the pivot 4 between the chamber 3 and the repeater 1. The point of engagement in the pivot 4 and the length of the sides of the chamber 3 is chosen so as to force the flexural flexible ear 2 of the repeater within its range of operation. 3 into such new positions as to achieve the heel shape of the shoe, which offers the best possible grip on any shape of the heel and tendon of the Achilles tendon.

Importantly, the design ensures that the flexibly moving ear of the heater 2, due to the excessive rotation of the chamber 3 in the forward direction, does not reach a position that would consequently impose excessive strain on the growth site as well as on the Achilles tendon itself.

Each position of the comat 3 is uniquely determined by the interconnection created between the comat 3 and the flexibly moving ear 2, on the flexibly movable ear of the heel 2, which is made with grooves 5a and pin 5b on the coma 3. While using the shoe, comat 3 cannot to take new or unwanted positions. The construction provides a solid connection between chamber 3 and repeater 1 in the set or.

desired position due to slots 5a and pin 5b.

The user can always re-set komat 3 to another or. a new position 20 by means of grooves 5a and pin 5b, since the construction provides complete repeatability in the interrelationship of the controller components.

In this way, the shape of the upper part of the heel 1 changes, which by different spatial positions of the flexibly moving ear 2 defines new shapes of the heel of the shoe. The user can thus adjust the shape of the heel of the shoe or heel. the pressure and thus the grip of the heel 1 according to the individual shape of the heel of the foot.

Foot shape data shows that the shape of the heel varies and can be very different from one individual to another. The shape of the heel along with the growth of the Achilles tendon may be straight or more curved. According to the data obtained by scanning human feet, the dimensional difference between the "straight" and "curved" shape of the heel along with the growth of the Achilles tendon is up to 10 millimeters.

io With the help of the heel grip controller according to the invention, it is therefore possible to change the shape of the heel portion of the shoe, thus providing a better grip for as many users as possible.

The person adjusts the comat 3 to the position that suits him best, depending on the shape of the foot in the heel area and, of course, his own feelings of comfort and grip.

The construction of the device according to the invention shows the following advantages over existing types of regulators:

- easy regulation,

- reliability,

- repeatability,

- Easy and inexpensive implementation.

Claims (2)

APPLICATION PATENTS 1. A heel grip regulator, marked stem, 5 that it consists of a heater (1), the upper part of which extends into the folding movable ear (2) and the chamber 3, with the front of the chamber (3) pivotally mounted in the heater (1) via a pivot (4), and the grooves (5), which are too flexible, move grooves (5a), and the pin (5b) on the inside of the comat (3). The heel grip controller according to claim 1, characterized in that the circular rotation of the heel (3) against the heel (1) with the appropriate shape of the heel (1) and the correct pivot point (4) of the heel (3) changes the shape and footwear in the heel region.
