The ski mount (1) comprises a housing (2) with a series of side walls (3) made in the form of symmetrical protrusions (4) along the entire housing (2); a locking element (5) for securing the ski boot axis and a control element (6) with a locking element (5) made with a protrusion in the lower part (7), which makes it possible to change the position of the locking element (5). The locking element (5) is made in the form of a strap (8) with a protrusion (9) in the front part and two vertical shelves (10) in the rear part, directed upwards and provided with hooks (11). The second pair of side walls (12) in its front part is provided with grooves (13), open upwards, and connectors (14) for the entry of the hooks (11) of the locking element (5). The housing (2) is additionally equipped with a plastic flexor (15) having guide grooves (16). The control element (6) is made in one piece with the housing (2) in the form of a key (17) directed to the rear of the housing (18) with its movable part (19). The second pair of side walls (12) in its front part in front of the grooves (13), open upward, is connected by a crossbar (20). The hooks (11) of the locking element (5) are directed towards the protrusion of its front part, and at a certain distance after the protrusion (9) in the front of the bar (8) of the locking element has a steep V-shaped protrusion (21) upwards. The flexor (15) is made flooded into the housing (2) and is additionally equipped with an element covering the key (22). The key element (22) is provided with an elastic guide groove (23) made around the entire upper part of the key (24). Flexor (15) is additionally equipped with an element included in all central lower technological grooves (26) of the elongated rear part of the housing (25). (see Fig. 1, 2, 3, 4, 5, 6, 7, 8)

The device operates as follows:

The design of the ski mount (1) allows you to fix - that is, lock the metal axis of the ski boot mounted in the sole of the boot in the grooves (13) of the front of the second pair of side walls (12) of the ski boot (1) - of the skier’s boot and free the boot without tilting the skier and without the help of hands (using a ski pole). (see Fig. 1, 2, 3)

Fastening.

Through the axis mounted in the sole of the ski boot, the skier exerts a vertical effect (top pressure) on the hooks (11) of the locking element (5) by the weight of the skier (see Figs. 1, 2, 3).

Due to the fact that the hooks (11) of the locking element (5) in the upper part have an inclined surface (for example, an angle of about 60 degrees), a horizontal component occurs (according to the rules of vector geometry, the vertical force is decomposed into a component normal to the surface and horizontal parallel to the ski surface) , which produces a displacement of the locking element (5) in the direction of the heel of the boot of the skier (towards the back of the body (18)) (see Fig. 1, 2, 3).

As soon as the grooves (13) of the front of the second pair of side walls (12) of the ski mounts (1) are released from the hooks (11) that go away at the moment of pressing into the connectors (14) for the hooks (11) to enter, the axis of the ski boot falls into the aforementioned grooves (13) (see Fig. 1, 2, 3).

When the locking element (5) is opened, a reverse force arises due to the fact that the rear wall of the V-shaped protrusion (21) of the locking element (5) presses on the flexor (15), where in the normal state between the rear wall of the V-shaped protrusion (21) the locking element (5) and the inner vertical surface of the flexor (5) there is an unstressed contact. The action on the hooks (11) of the locking element (5) is transmitted to the rear wall of the V-shaped protrusion (21) of the locking element (5), that is, during the displacement of the locking element (5) when the locking element (5) is opened, the rear wall of the V-shaped the protrusion (21) of the locking element (5) simultaneously presses on the inner vertical surface of the flexor (15), where elastic deformation of the flexor (15) occurs, which with effort returns the system to an unstressed state. The hooks (11) of the locking element (5) prevent the ski boot axis from coming out of the grooves (13) of the front of the second pair of side walls (12) of the ski mount (1). The ski mount (1) comes in a relaxed, closed state. (see Fig. 1, 2, 3)

Opening ski mounts.

To open the ski mount (1), it is necessary to move the hooks (11) of the locking element (5) and allow the skier to remove the axis of the ski boot from the grooves (13) of the front of the second pair of side walls (12) of the ski mount (1). To do this, the skier with a ski stick exerts vertical pressure (presses) on the key (17) (control (6)), as a result of which the protrusion in the lower part of the control (7) presses on the protrusion of the strap (9) of the locking element (5), at the moment of pressing the hooks (11) of the locking element (5) into the connectors (14) for the hooks (11) to enter. The locking element is opened and the ski boot axis is released. In this case, when the locking element (5) is opened, a reverse force arises due to the fact that the rear wall of the V-shaped protrusion (21) of the locking element (5) presses on the flexor (15), where in the normal state between the rear wall of the V-shaped protrusion ( 21) the locking element (5) and the inner vertical surface of the flexor (5) there is an unstressed contact. The impact on the protrusion of the strip (9) of the locking element (5) is transmitted to the rear wall of the V-shaped protrusion (21) of the locking element (5), that is, during the displacement of the locking element (5) when opening the locking element (5), the rear wall V- the shaped protrusion (21) of the locking element (5) simultaneously presses on the inner vertical surface of the flexor (15), where elastic deformation of the flexor (15) occurs, which with effort returns the system to an unstressed state, that is, the hooks of the locking element return to the grooves (13) front of the second pair of side with Yenok (12) for fastening ski (1) (see. Figs. 1, 2, 3).

The main difference between the proposed ski mount is that the control element (key) and flexor are made in one piece with the body, which eliminates the accidental loss of the flexor or key, which can lead to emergency operation of the ski mount. In addition, due to the implementation of the locking element with a V-shaped protrusion does not require the use of a spring, which can also fall out or become unusable during operation of the device.

All of the above indicates the fulfillment of the technical task, namely the creation of a reliable ski mount, the main mounting elements of which are most tightly fixed relative to each other, and about the industrial applicability of the inventive ski mount.
