Description

The utility model relates to the field of sports, namely to ski bindings containing an elastic element (flexor) that interacts with the sole of the ski boot. Anchorages are intended for attaching ski boots with an axial attachment system for cross-country and other types of skis and ski rollers for all types of skiing, for sports, tourism, free skiing, etc.

The main purpose of the elastic elastic element (flexor) in modern sports ski mounts is to transfer additional load from the boot to the ski. When the skier moves, the flexor, deforming, affects various sections of the sole of the ski boot when the boot makes a movement around an axis made in the front of the sole (in the toe of the sole), which is fixed in the lock located in the mount body.

Known flexor for ski mounts according to the patent of the Russian Federation for invention No. 2518188 (published on August 27, 2013), installed in a ski mount containing a lock for detachable attachment of the ski boot, said lock being made with a groove for placing and holding the axis of the ski boot, and the mount is made with the ability to hold the flexor in place so that the groove of the flexor is aligned with the groove of the lock, so that when the axis of the ski boot is held in the groove of the lock, it is also in the groove of the flexor and thus prevents the loss of the flexor. Also, the flexor in this invention can be made multicomponent (from combinations of different materials), which provides various characteristics when interacting with the sole of the ski boot and can consist of several sections interacting with different sections of the sole of the boot.

The disadvantage of this mount is the insufficient contact area of the flexor and the toe of the sole, since the width of the flexor and the contact area with the ski boot is limited by the distance between the shelves in which the boot axis is held.

Known flexor according to the patent of the Russian Federation for the invention No. 2526289 (published on 08/20/2014). The invention relates to multi-element flexors for ski mounts, in particular mounts for racing or hiking skis. The flexor comprises a flexor element which is connected in a detachable manner to the ski mount. The flexor element is made with a shock absorbing soft part and with a rigid base attached to it, made with a part of a snap-in connector for attaching a multi-element flexor to the ski mount. The flexor element may have several sections for interacting with different sections of the sole. The flexor element may have recesses and channels open downward.

The disadvantage of this solution is the structural limitation of the width of the contact zone with the sole, since the flexor is located between the fastening shelves holding the boot axis and has a constant width.

The limited size of the contact zone between the flexor and the sole of the sole leads to a high specific load on the elastic elements of the flexor when it is deformed from the sole of the sole when it is rotated on the axis, which leads to its low life and insufficient reliability due to the possibility of rupture and other damage during operation, which is especially important when using mounts in sports competitions.

The technical result to which the proposed utility model is aimed is to improve the operational properties of the flexor and increase its service life, as well as the ability to reduce the requirements for the elastic properties of the material from which the flexor is made, by increasing the contact area of the flexor surface with the sole of the ski boot, and the associated with this, the reduction of specific loads per unit surface flexor.

The technical result is achieved in a flexor comprising a front elastic element made of elastomer, characterized in that the upper part of the front elastic element interacting with the sole portion is made wider than the lower part, so that the front elastic element in cross section is made along mushroom-shaped.

This allows you to significantly increase the contact area of the surface, the front elastic element of the flexor and the sole area by increasing the width of this elastic element, compared with the width of the flexor at the point of attachment to the mount. This allows the use of less rigid materials for the manufacture of elastic flexor elements while maintaining high return forces, since due to the increased contact area, the specific load on the contact surface decreases, which allows to increase the resource of the flexor elastic element, as well as to increase the possible range of application of one flexor for different riding styles.

The flexor is preferably injection molded

The flexor is preferably fixed in the mount housing.

It is preferable to use materials that retain elastic properties at low temperatures for the manufacture of flexor.

In one embodiment, the flexor further comprises at least one additional elastic element.

Preferably, the flexor is made of two elastic elements, between which there is an opening for the axis of the ski boot.

In some embodiments, at least one elastic element of the flexor can have cavities and / or channels that can be opened on the sides of the flexor and / or open down in various combinations. Moreover, the cavity and / or channels open on the lateral sides of the flexor can be made through and / or blind, with the formation of a wall inside the flexor. Cavities and / or channels can have a cross-sectional shape - a circle, an ellipse, a curved shape, a polygon with sharp or rounded corners, as well as combinations thereof. These cavities and / or channels can form a honeycomb structure of many walls.

Preferably, the cavities and / or channels are made identical in cross-sectional shape.

The shape of the channels and / or cavities determines the flexor deformation parameters that are most suitable for a particular riding style.

For skating, it is preferable to make the elastic element of the front part of the flexor more rigid due to its execution with horizontal channels of small cross section.

For the classical style, where large angles of rotation of the ski boot are required, it is preferable to perform an elastic element with vertical cavities of a larger cross section, allowing significant flexor deformations.

For the combined style, it is preferable to design a variant with intermediate stiffness, for example with horizontal cavities separated by horizontal walls.

For the production of flexors for a different type of skiing (classic, mixed or skating) as well as different skier weights, it is preferable to use the same topology when made from materials with different elasticities, which determines the necessary rigidity of the flexor.

In some embodiments, the flexor can be made with a stiffer base than the material of its elastic elements, with which it is connected in one piece, preferably by casting with a fixed part, or by two-component casting, or by welding, or by gluing. This base can be made with lateral and / or longitudinal protrusions. In this case, the flexor can be fixed in the mount housing using the tabs in the specially made grooves of the mount housing.

The elastic parts of the flexors (2) are made with cavities (7) open down.

The technical result claimed in the utility model is achieved in the following device. Flexor (1) is made as a whole of the front (2) and rear (3) elastic elements, between which there is an opening for the axis of the ski boot (20). In the shock-absorbing body of the elastic elements, cavities (5) and / or channels (6) are made, which can be opened from the lateral sides of the flexor (1) and / or cavities (7) and / or channels (8) open downwards, in various combinations. In this case, the front part (2) interacting with the toe of the sole, in its upper part (23) in contact with the toe of the sole (15) is made wider than in the lower part (24), the width of which is limited by the distance (21) between the shelves (22 ) the mounting housing (13) in which the flexor is fixed. The cavities (5) or channels (6) open sideways are made through, and they can also be made blind, with the formation of a wall (7), inside the flexor (1), parallel to the plane of its symmetry. Cavities (5, 7) and channels (6, 8) can have different shapes - with sharp edges, rounded, made in the form of cylinders, prisms, curved shapes, polygons and their combinations. In fact, these cavities can form a honeycomb structure of many walls. Also, the cavities (5, 7) or channels (6, 8) can be made identical in cross section. The shape of the channels and cavities determines the flexor deformation parameters that are most suitable for the given riding style. For example, for skating, it is preferable to perform a more rigid shock-absorbing part of the flexor with horizontal channels (6) of small cross section. For the classical style, where large angles of rotation of the ski boot are required, it is preferable to perform a shock-absorbing part with vertical cavities (7) of significant cross-section, allowing significant flexor deformation. For the combined style, it is possible to execute a variant with intermediate stiffness, for example, with horizontal cavities (5) separated by horizontal walls. For the production of flexors for different types of skating (classic, mixed or skating) as well as different skier weights, it is possible to use flexors with the same topology, but made of materials with different hardness, which determines the necessary rigidity of the flexor.

The flexor can be made with a stiffer base than the material of the shock-absorbing sections (2, 3), base (4), with which it is connected in one piece, preferably by casting in the form with a fixed part (4), two-component casting, welding, gluing or other method. This base (4) may have lateral (11) and / or longitudinal (12) protrusions. A flexor of this design can be fixed in the mount housing using the protrusions (11, 12) of the rigid part (4) in specially made grooves (19) of the mount housing (13), which can be located in the area of the front section (2) and / or rear section ( 3).

Flexor works as follows:

The front part of the flexor (2) interacts with the section of the sole (15) in front of the axis (14) (with the toe of the ski boot). The back of the flexor (3) interacts with a portion of the sole (14) located behind the boot axis. When interacting with the sole of the ski boot under load, the flexor (1) is deformed in that part (2, 3) that is pressured by the corresponding part of the sole (15, 16) when the ski boot is rotated around the axis (22). For example, when lifting the heel of the ski boot and turning it on the axis (14) forward, the front of the flexor (2) is compressed by the toe of the ski boot (15). When the boot is horizontal (with the heel down), pressure is exerted on the back of the flexor (3). When lifting the ski and removing the load from the sliding surface, in the presence of the back of the flexor (3), as a result of the simultaneous interaction of the front (2) and rear (3) parts of the flexor with the sections of the sole of the ski boot (15) and (16), the attachment body (13 ) and, accordingly, the ski is installed at a structurally predetermined angle α relative to the sole.

Such a predetermined position of the ski relative to the sole of the ski boot is necessary for a certain technique of sports skiing, especially when skating. It is also possible to preload the parts of the flexor (2 and / or 3) when installing the ski boot in the mount for a higher restoring force.

Thus, by increasing the area of contact of the surface of the flexor with the sole of the ski boot, and the associated reduction in specific loads per unit surface of the flexor, the claimed technical result is achieved in the form of improving the operational properties of the flexor and increasing its working life, as well as the ability to reduce the requirements for elastic properties the material from which the flexor is made.
