Description

The utility model relates to human safety systems, in particular, used in the event of an avalanche, or in other emergency situations when riding a sports apparatus on ice, snow, water and other sliding surfaces. It relates to devices for securing the mechanism of holding the boot on a sports apparatus and to the device for detachable connection of the base plate and the platform on which the athlete’s boot is fixed. Designed for sports equipment - a sliding board, which, for example, is made in the form of a mono ski, snowboard, kiteboard or wakeboard. The device for attaching shoes to the board is used for training on a sports equipment, for example, when riding a snowboard in avalanche conditions.

The prior art invention is known "System containing a detachable device for connecting the base with the support plate", patent RU 2465942, FR 0701036 from 13.02.2007, publ. 11/10/2012, IPC A63C 9/00, which comprises a detachable connection device for the base plate and fixed fixing means, the fixed fixing means comprising a latch comprising a first locking finger, and the finger extends between the free end and the grip end of the first latch, as well as a holding device boot. The invention allows to exclude the use of any tool for connecting or disconnecting the base plate relative to the base, and also simplifies the operation of the fixed fixing of the base plate in relation to the base. However, the invention does not solve the problem of separation of the fastening at critical loads of a certain size.

Known invention "Snowboard", patent RU 2344864, publ. 01/27/2009, IPC A63C 5/06, A63C 17/01, in which there is a platform for attaching shoes, which is divided in the transverse plane into two platforms and which are equipped with at least two mechanical units, as well as a rigid base. The invention allows to increase the maneuverability of the snowboard due to its better controllability during tilting, however, when descending from the steep slopes of the mountains it does not solve the problem of separation of fastening and reducing the risk of injury.

The invention is known "Binding Snowboard Mount Release System", patent PCT / ES 2006/000545, WO 2007/039655, publ. April 12, 2007, IPC A630 / 088, which is equipped with an electronic sensor device having a detector for detection, a hand release handle located in a portable case, and an electronic receiving device. The system allows you to reduce the number of injuries resulting from skiing and similar types of sports equipment due to the fact that it is possible to open the mounts, while the system can be activated voluntarily or forcibly. However, the system uses electronic devices, which can lead to the fact that there is no one to press the panic button, i.e. in case of loss of self-control, for example, panic, loss of consciousness, etc., or the device will not work due to failure, for example, of chemical batteries at low temperatures, since low temperatures affect them negatively. In addition, the system requires periodic verification (verification), like any rescue tool, which is difficult to accomplish in field conditions.

A useful model is known “Device for ensuring the convenience of using mono-skis”, patent RU 28986, published 04/27/2003, IPC A63C 5/00, in which the device is placed between the athlete’s leg mount and the upper surface of the mono-ski in the form of two profile disks with means for rigid attachment to the upper surface of the monopole, means for rigidly attaching the athlete’s legs to it, has disks that are mounted coaxially to each other, and on the disks there is a limiter and a latch rigidly fixed to the disk, equipped with a holding her head. The device allows you to create double skis that evenly and symmetrically distribute the load along sliding surfaces under all driving conditions. However, slipping the ski boot in the mount is possible only with axial rotation relative to each other, which does not solve the problem of unfastening the boots in a critical situation, but only the distribution of loads on both skis in the longitudinal direction.

Known invention of "Double skiing", patent RU 22618, publ. 04/20/2002, IPC A63C 5/00, in which there are two movable parts mechanically connected to each other and with an elastic central beam with a cargo area and with a fastener, an elastic element to which a cargo platform with a skier boot mount is attached, and the suspensions are additionally elastic elements. The invention improves the convenience of mounting and expand the functionality. However, in critical situations, when the force on the platform from the side of the athlete’s leg exceeds the shear force of the latch, the fastening allows not to release it, but only to ensure a parallel position of the sliding surfaces to each other and the plane of the sole of the boot with the ski straight and when skiing.

The invention is known, "A node containing a sliding board, and a device for attaching shoes to a board", patent RU 2433851, FR 0604664 from 05.24.2006, publ. 11/20/2011, IPC A63C 9/00, in which there is an intermediate strip made with the possibility of installation on the upper side of the board, a shoe fastening device on the board, and comprises a supporting side resting on the intermediate strip, the intermediate strip comprising a receiving side for the device fasteners, and the receiving side of the intermediate plate and the supporting side of the fastening device are mechanically compatible. However, the receiving side of the intermediate plate and the supporting side of the fastening device are poorly compatible or even completely incompatible mechanically, gaps are formed. The invention allows to improve the connection of the fastening device with the sliding board, but only for cushioning and stability and does not solve the problem of unfastening in critical situations.

Also known is the invention "System for dropping a snowboard in case of emergency", patent RU 2543405, publ. 02/27/2015, IPC A63C 9/00, containing a wireless transmitting module, a module for detaching equipment, consisting of two parts connected by a rod according to the principle of a hinge loop. The system is designed to ensure human safety, in particular, in the event of an avalanche, or other emergency situations when riding a “snowboard” sports equipment, it provides the necessary speed and reliability of the system as a whole, and its elements to release the athlete (snowboarder ) from the snowboard by opening, unfastening or breaking the snowboard mounts, by mechanically separating the legs of the snowboarder from the sports equipment. However, such a system will not help a snowboarder who has lost self-control as a result of a panic or loss of consciousness in an avalanche, because to unfasten you need to press a button or pull a lever on clothes or on a board. In addition, the use of a squib is expensive and unreliable, because The squib is a disposable part. In addition, any life-saving tool requires regular checking, which is difficult to carry out in field conditions, but in cold weather batteries or batteries lose their capacity and do not work.

Closest to the proposed technical solution is the invention of "Monolith", copyright certificate SU 1584972, publ. 08/15/1990, IPC A63C 5/00, containing an installed support pad with an elastic element on the outer surface of the elastic base of the monolith, a groove is made in the back of the support platform to accommodate the platform, and the platform in the back is equipped with a boot heel mount, and in the front parts - grip for the toe of the boot. Mounting the mono-ski allows you to increase the efficiency in use by ensuring the ease of performed acrobatic elements, however, it does not provide detachment of the boot at critical loads with a given value.

There is currently no effective safety solution for critical cases in, for example, avalanches. This problem has not been solved with the help of mechanical devices, which would ensure reliable fastening without a “pull” and unreasonable loosening of fastening, but reliable unfastening of the boot from a sports apparatus under critical loads. Standard fastenings can be opened in the event of a fall only with the additional efforts of the athlete. Those. fastenings open only in some specific cases, not determined by the efforts of the impact on the athlete.

The main causes of death of snowboarders in avalanches are hypoxia, asphyxia, hypothermia and injuries incompatible with life. It is necessary to increase the likelihood of an athlete's survival in an avalanche, in particular from injuries.

This requires the release of the athlete (snowboarder) from the snowboard by opening, unfastening or breaking the fasteners, which is ensured by the mechanical separation of the legs of the snowboarder from the sports apparatus.

When an athlete enters an avalanche, an uneven increase in the load on individual parts of the snowboard and individual parts of the athlete’s body occurs, which leads to the impact on the body of a force exceeding the maximum permissible. Moreover, due to the high energy of the moving masses of snow, the loads on individual parts of the snowboard and the athlete’s body are often directed in different directions. At the same time, the speeds of movement of the snowboard and the body of the snowboarder are very different. For example, the snowboard stops, and the body continues to move forward. In this case, the snowboard plays the role of an anchor in the relatively slow lower layer of the avalanche. And the athlete’s upper body is exposed to the relatively fast upper layers of the avalanche. Reverse movement is also possible. In this case, the snowboard is in the upper (relatively fast) layers of the avalanche, and the body is in the lower (relatively slow) layers, the snowboard plays the role of a sail. In this case, various types of traumatic efforts arise. For example, an athlete experiences an effort stretching his body. Analogue: medieval "rack". The consequences are injuries to the spine and joints. There may be an effect that non-uniformly deflects the athlete’s legs in a rigidly fixed boot by a critical value, which leads to damage to the main joints and spine.

The goal is to reduce the number of injuries resulting from snowboarding and similar types of sports equipment, which can be done due to the fact that the separation of the fasteners is ensured under loads exceeding critical. At the same time, it is required that the boots are securely fastened under normal sliding conditions and are separated from the snowboard when the load on the mount is higher than critical. This will protect the athlete from deflecting influences from the side of the snowboard board on the body, regardless of the direction of impact and the resulting torque.

Separation of the fastening should occur, if possible, only in critical situations, when the force on the platform from the side of the athlete’s leg exceeds the predetermined amount of force to open the latch. At the same time, it is required to ensure the release of both athlete's legs, fixed in boots, with minimal mismatch. In addition, in the case of normal impacts during riding and performing stunts, the opening should not occur. When putting on the mount, it is necessary to normalize the holding force of the mount on the ski so that the mount that is too loose does not unexpectedly release the boot when the user moves while riding, or that the athlete does not tighten the mount excessively.

The technical result of the proposed utility model is the creation of a system for dropping a sports apparatus in an emergency, providing the necessary efficiency at critical loads and improving the connection of the fastening device to the sliding board.

The technical result is achieved due to the fact that the fastening of the sliding board, discharged in emergency situations, contains at least one support plate with at least one elastic element and at least one platform. A support plate is rigidly fixed on the upper surface of the sliding board, in the back of which at least one landing hole or groove is made to accommodate the platform fastener. The platform at the rear is provided with at least one fastener located under the heel of the boot and secured with respect to the standard mount. In the front of the mount, the support plate and platform are provided with at least one grip located under the toe of the boot. The novelty of the utility model lies in the fact that the base plate is provided with a lock, which is made in the form of a cam with a conical surface facing the counter surface of the platform fastener, and the base plate is provided with at least one rod connected to the elastic element. The platform is rigidly connected to the boot mount. The platform fastener is provided with a mating conical surface facing the retainer of the base plate. Moreover, at least one conical surface of the platform fastener is made in total greater length than the cone surface of the retainer, to exclude the involuntary separation of the platform and the support plate during bending of the sliding board when performing tricks and to ensure guaranteed detachment of the support plate from the platform. The support plate retainer is movable relative to the platform fastener, the retainer cam is pivotally connected to the thrust and the cam thrust, for example, is pivotally connected to the elastic element of the retainer, which consists of at least one spring and one turnbuckle. In this case, the lanyard is rigidly attached either to the support plate or to the lock rod of the second mounting platform of the sliding board. In the particular case, the mount contains one base plate with two landing holes for accommodating the fasteners of two platforms, each of which is attached to the corresponding athlete’s shoe. The mount may also contain two support plates, each with a landing hole for placement in each of them, respectively, of the mounting parts of the platforms, each of which is fixed to the athlete’s shoe. The platform fastener can be made in the form of a truncated cone, facing a narrow part to the bottom surface of the platform, and mating with the conical surface of the cam of the retainer of the base plate. In this case, the cam is movable in the transverse direction from the fastener by an amount sufficient to release the platform fastener when the fastener moves in an orthogonal plane. The mount may contain one base plate with two landing grooves for placement of fasteners of two platforms, each of which is fixed to the athlete’s shoe. The mount may contain two base plates with a landing groove for placement in each of them, respectively, of the mounting parts of the platforms, each of which is fixed to the athlete’s shoe. Also, the platform fastener, in the lower part, can be made in the form of a cylindrical helical surface, mating with the cylindrical helical surface of the cam of the clamp of the base plate. In this case, the latch cam is rotatable around an axis parallel to the axis of the fastener by an amount sufficient to release the platform fastener when the fastener moves in an orthogonal plane. In addition, the support plate can be made up of at least two parts rigidly attached to each other, while the upper part of the support plate performs the function of an abutment for the locking cam. At least one groove can be made in the support plate, in which the lug cam rod is axially displaceable. And, in the particular case, the spring of the elastic element is made by a tension spring.

Resettable in emergency situations is arranged as follows.

The mount consists of a support plate (1) and a platform (2). The support plate (1) is rigidly attached to the upper surface “a” of the monolith (3) with bolts (4). The platform (2) is fixed to the standard mount (5) with bolts (6). The athlete’s shoe is normally held by the mount (5). Mounts (5) for a snowboard or for any other type of mono-ski use standard ones made by most manufacturers. The support plate (1) is connected to the platform (2) by means of two locks - the front, under the toe of the boot in the mount (5) and the back - under the heel of the boot in the mount (5). The front lock (shown in Fig. 6.) has a groove (7) (Fig. 8) in the base plate (1) into which the protrusion (8) (Fig. 1, 5, 6) of the platform (2) is inserted. The front lock is designed to hold the toe of the shoe and the relative positioning of the plates when inserting the fastener (9), which is a detachable part of the fastener. It does not carry significant power loads. The protrusion (8) can be made as a separate part and attached to the platform (2) with a bolt (10) and screws (11). The lateral surfaces of the protrusion (8) serve as guides when driving the boot in the mount (5) with a fixed platform (2).

The rear lock performs the main function of the model - it fixes at rated workloads when riding in normal mode and releases a boot with a platform (2) in case of traumatic, exceeding rated loads. The platform (2) is equipped with a fastener (9), which can be performed in several versions. In FIG. 2 shows the design of the fastener (9) in the form of a cone, the narrow part of which is facing the platform (2), and the wide part of which is installed in the cylindrical hole of the base plate (1). During the establishment, the lower edges of the cone are rounded and slide along the side walls of the cylindrical holes of the support plate (1), which serve as guides.

When performed with a rail (Fig. 7), the fastener (9) is made in the form of a rail, concave and convex surfaces, on the concave part of which are placed oblique teeth, and the convex side is cylindrical. The fastener (9) in the form of a rail is inserted into the groove “b” of the support plate (1) until it stops with the surface “c”.

The base plate (1) is equipped with a latch, which is made in the form of a cam (12) (Fig. 3) with a conical surface "g" facing the counter surface of the mounting part (9) of the platform (2). The counter conical surface "g" of the fastener (9) of the platform (2) is facing the cam (12) of the support plate (1). Moreover, the conical surface of the fastener (9) of the platform (2) is made of a total greater length than the conical surface of the cam (12).

The cam (12) in execution 1 (Fig. 4) is made in the form of a segment in which the side facing the support plate (1) is cylindrical and the side facing the fastener (9) is conical.

Cam (12) in execution 2 (Fig. 5) is made in the form of a disk with a month-shaped groove "d". The outer surfaces of the disk are cylindrical and placed in the groove "b" of the support plate (1). The concave surface of the groove “d” of the cam (12) is cylindrical, and the convex surface of the groove “d” is made with counter oblique teeth mating with the oblique teeth of the rail of the fastener (9). The cam disk (12) is mounted on the support plate (1) with a bolt (13) with the possibility of rotation. Thus, the cam (12) is made in the form of a rail with an oblique thread on a concave surface. The angle of the thread is approximately 30 degrees from the vertical.

In both version 1 and version 2, a thrust (14) is pivotally attached to the cam (12).

The latch in the form of a cam (12) of the support plate (1) and rods (14) is made with the possibility of movement relative to the fastener (9) of the platform (2). The latch cam (12) is pivotally connected to the thrust (14) and the thrust (14) of the cam (12) is pivotally connected to the elastic element of the latch, which consists of at least one spring (15) and one turnbuckle (16). In version 1, two rods (14) are predominantly used, which are fixed to the cam (12) (Figs. 3 and 4). In version 2, one rod (14) is mainly used, which is fixed to the cam (12) in the form of a disk. In this case, both in that and in another design, the rods (14) can be rigidly fixed as directly on the snowboard. This is possible with one fastening, for example, if the platform (1) is released, for which the fasteners (9) are on the same platform (1), i.e. the platform is made in the form of one part immediately under two or one leg.

If two support plates (2) are made and two platforms (1) are installed on them under each athlete’s leg, then two or one rod is connected to the tension spring (15) and the lanyard (16), which is connected to the second mount with the support plate (2) ) and platform (1) (Fig. 9). In this case, the thrust with an elastic element is simultaneously a synchronizer for unfastening both fasteners simultaneously.

In all versions in the assembled state of the fastenings, the cam (12) is pressed against the cone of the fastener (9) of the platform (1) by means of a rod (14) and an elastic element consisting of a spring (15) and a turnbuckle, (16) and acts as a synchronizer. The rod (14) can be made of a steel cable with a diameter of approximately 1.5-2 mm. The traction force (14) receives the tension from the tension spring (15) and the cam (9) is pressed tightly along the conical surfaces, securing the entire platform under each shoe placed in a standard mount. Thus, the platform (1) with the fastening of the snowboard, in which the athlete’s foot is fixed, is attached to the snowboard. With sufficient traction (14), which is achieved by adjusting the lanyard, the connection of the base plate (2) and platform (1) is very strong. In FIG. 2, 3, 6, 7, support plates (2) are shown, consisting of several parts fastened together.

The support plate (1) is equipped with one or two rods (14) passing through it, connected to an elastic element. Moreover, the lanyard (16) and the spring (15) are pivotally interconnected. In this case, the lanyard (16) is rigidly attached either to the support plate (2) or to the rod (14) of the retainer (12) of the second platform (1) for attaching the sliding board.

Dividing the base plate (2) into several parts is more technologically advanced and allows producing guides for precise positioning (without slipping) of the connection of the base plate (2) and platform (1) with the fastener (9), grooves for the cable to pass through it without jamming and biting .

Thus, in the cocked position, the mount holds the shoe firmly in the standard mount, rigidly connected to the platform (1). The platform (1) is held for the required force by the cam (12) pressed along the conical surface.

For the athlete’s convenience, a scale in kg can be placed next to the turnbuckle (16), showing the pressing force of the platform (1) during riding and the force in kg of the critical load, in which the cam (12) due to the spring elasticity (15) when exposed to the fastener parts (9) will move to its extreme position and release the fastener (9).

To exclude the involuntary separation of the platform (1) and the base plate (2) when bending the sliding board during tricks and to ensure guaranteed detachment of the base plate from the platform, one cone surface of the fastener (9) of the platform (1) is made of a total longer extent than the cone surface cam (12) retainer.

The proposed mounting design works as follows.

When hit in an avalanche there is a strong pressure of the snow masses on the snowboard (its upper plane). The body of the athlete pulls to the side opposite to the board. There is an effort to tear the board from the leg. In this case, the cone of the fastener (9) of the rear lock starts moving up (view BB Fig. 3 execution 1 and view DD-Fig. 7 - execution 2) and pushes the cam (12) to its extreme position. The cam (12), in turn, overcoming the thrust resistance (14), moves away from the fastener (9).

In execution 1, the cam (12) slides along the conical surface of the fastener (9) with simultaneous retraction to the side (Fig. 3).

In version 2, the cam (12) in the initial position is connected along the conical surfaces of the teeth that are engaged, fastening the fastener (9) of the platform (1) in the form of a rail with an oblique thread on a concave surface with the cam (12) in the form of a disk with a month-shaped hole "e", the internal surface of which has a mating thread. Since the cam disc (12) has an axis of rotation around the axis (13), when the rail of the fastener (9) moves up, the cam disc (12) rotates clockwise, moving along an oblique thread. In this case, the spring (15) of the elastic element is tensioned through the rod (14) (Fig. 5). On top of the cam disk (12) is fixed with a metal plate with a hole for the platform rail (1) with a bolt (13).

When the cam (12) is retracted, the platform (1) is separated from the support plate (2) and, accordingly, the leg in the mount is separated from the snowboard. One foot is released.

Further, the cam (12), not restrained by the conical surface (s) of the fastener (9), moves away from it under the action of the traction force of the elastic element, transmitting a signal (weakening force) to unfasten the second platform (1) through the weakened rods ( 14), the spring (15) and the lanyard (16) compressed in this case. The second mounting platform (1) is made mirror-like, so the movement of the cam (12) of the second platform (1) (conditionally shown in the diagram in Fig. 9) from the fastener (9) of the second platform (1) is carried out after the separation of the platform (1) and the support plates (2) of the first fastening as a result of easing the tension of the thrust (14) of the platform (1) of the second fastening. This allows the cam (12) of the support plate (2) of the second fastening to change position and allow the cone of the fastener (9) to leave the seat of the support plate (2) with minimal upward force. Thus, the second leg is also freed from the snowboard. The elastic element, consisting of rods (14), spring (15) and turnbuckle (16), performs two functions. It provides sufficient force to prevent spontaneous unfastening of the platforms (1) of the mounts and the simultaneous disappearance of the locking force on the rods (14) of the second mount. The fastening works in a similar way with version 2. The only difference is that the cam (12) and the fastener (9) have several conical surfaces.

The lanyard (16) allows you to adjust the tension of the rods (14) of both fasteners, and hence the force at which the cams (12) of both fasteners will be pushed out by the conical surfaces of the fasteners (9). Lanyard (16) is a force regulator in which the snowboarder is freed from the board without injuries.

Moreover, with that and with another design, the elastic element is also made in various designs. For example, the spring may be a tension spring (see FIG. 9) or a compression spring (see FIG. 10).

Execution 2 allows to increase the course of rods. However, both versions, which are not the only possible ones and are given as preferred, allow eliminating the possibility of unfastening the mounting platforms during stunt riding and, at the same time, protect the athlete in critical situations during an avalanche.

So, for example, if it enters the snow mass during execution 1, additional pressure of snow-ice fragments of the interference fit (14) and an elastic element from a tension spring (15) and turnbuckle (16) are possible (Fig. 9). As a result, the force pressing the cams to the cones will increase, and, accordingly, the greater, and most importantly unpredictable, force to unfasten the board.

When using a compression spring (15) (Fig. 10) and when additional pressure of snow-ice fragments of interference (14) occurs, for example, if a piece of ice hits the rods (14) and an elastic element consisting of a compression spring (14) and a lanyard (16), this will only weaken the locking force on the cams and, accordingly, weaken the force necessary to unfasten the fastening, since the actuation is carried out from the pressure on the board in the orthogonal plane. When using a tensile spring (Fig. 9), this drawback remains, since the external forces from the impact of snow-ice masses on the rods (14) will be in the plane of the board sliding or in any other direction having a projection component on the plane of sliding, sufficient for horizontal displacement bending rods (14) and elastic elements, which can lead to their jamming. In the version with compression spring (15), the destruction of the rods (14) will not lead to negative consequences. To avoid accidental operation with all versions helps lightweight casing, which is not shown in the drawings.

Thus, the utility model offers a technical solution for fastening in the form of a mechanical device based on the interaction of conical surfaces and elastic elements, the principle of which is shown in kinematic diagrams (Figs. 9 and 10). The unfastening of the fastening occurs due to the interaction of one movable element by means of rods with an elastic element, the tension of which can be regulated by a turnbuckle. Thus, an improved fastening system is proposed in which dropping the fastening of a sports apparatus in an emergency provides the necessary efficiency under critical loads.

The proposed utility model can be installed on most commercially produced snowboards using commercially available mounts.
