Abstract

The invention relates to devices for ensuring personal safety when skiing. An emergency ski release device consists of a base and a rear stop, which are fastened to a ski, and also a platform, upon which at least one part of a ski binding can be mounted and which has openings for pins in the front and rear ends thereof. The rear end of the platform mates with the rear stop, and the front end of the platform mates with the base, where it is fastened with the aid of a locking device that can be unlocked by the skier, thereby separating the platform from the ski. A release mechanism consists of a pyrotechnic thruster and a retainer for a receiver module, said retainer engaging with a locking protuberance on the base and being openable by actuation of the pyrotechnic thruster so as to disengage from the locking protuberance on the base. This enables a skier to free their foot rapidly from a ski.

Description

DEVICE FOR EMERGENCY SKI HEATING AND OPENING MECHANISM OF SUCH DEVICE

The invention relates to devices for ensuring human safety in necessary cases, in particular, in the event of an avalanche, or other emergency situations when skiing, namely: it is an emergency means of cleaving the legs from the ski.

Close in technical essence to the claimed invention is the solution according to US patent (publication number US7815213 B2, application number US 11 / 624,997), in which the back (heel) part of the ski mount can be mechanically pushed back, which allows the foot in the ski boot to be released from the mount . The ejection mechanism is located between the heel and the front (cape) parts of the mount, under the foot of the boot and is made as an electric drive. The mechanism is driven by an electric motor. The disadvantage of this solution is that when it is triggered, considerable effort is required to push the heel out, especially if the skier presses on it. In this case, the electric motor of the electric drive should be significantly energy-intensive, while it will have low efficiency and will be exposed to aggressive media all the time, especially the influence of low temperatures that reduce its effectiveness when the ejection mechanism is activated. At the same time, before the actuation, that is, in the process of ordinary skiing, the given mechanism of such an ejection must be subjected to significant vertical and horizontal loads (mounting backlash), which can render it unusable. The disadvantages include the not entirely successful solution of the location of the extrusion mechanism, which may be subjected to pressure from ski boot, including, in case of falling between the boot and the mechanism of a foreign object: ice, stone, branches, etc. The structural complexity of the mechanism reduces its reliability, which determines the health and life of the athlete.

5 Also close in technical essence to the claimed invention is the decision according to the US patent (publication number US20050167950 A1, application number US 10 / 336,564), in which the effect is also on the back (heel) of the ski mount. At the same time, it is not pushed out, but is stretched out mechanically, which allows the foot in the ski boot to be released from the mount. The pulling mechanism is located behind the heel of the mount and is designed as an electric drive. At the same time, the mount itself is mounted on runners that do not allow it to shift horizontally during riding and, at the moment the device is triggered, set the direction of the rear mount offset.

The disadvantage of this solution is that when it is triggered, considerable effort is required to stretch the calcaneal part, especially if the foot of the skier presses on it and creates additional friction that can impede or completely block the mechanism. At the same time, before the actuation, that is, in the process of ordinary skiing, the given mechanism of such an ejection must be subjected to a significant vertical and horizontal load, capable of rendering it unusable. The disadvantages include the fact that the runners, and

25 also, snow or ice can accumulate in the space between the rear of the mount and the pulling mechanism, which quite often cling to the ski mount at the time of use; these mechanical obstacles will block the operation of the mechanism and violate the standard disengagement procedure, or completely make it impossible. The mention in the patent that its mechanism is based on the operation of the solenoid, that is, on the magnet, due to the fact that interference may occur in its operation due to magnetic anomalies frequently encountered in the mountains, as well as the unreliability of the magnet, can be considered not entirely successful. with sharp accelerations.

Thus, the general task of the technical solution for uncoupling the athlete’s legs from the ski is to create such a device that would be highly reliably isolated from the mechanical obstacles of the environment, would not be subjected to significant mechanical stress (load) during regular skating, while carrying out the opening carried minimal physical exercise. In this case, the objective of the claimed device is the quick release of the skier’s legs from the ski (s), that is, the creation of an emergency and almost instantaneous dropping of the ski in case of emergency, which device provides the necessary speed and reliability of the device as a whole and its components. A quick release from the ski (its dropping) is necessary because this eliminates the effect of sailing created by skis in the avalanche, which causes the person to be drawn into the snow stream, which, in turn, critically reduces the chances of survival. In addition, the faster the ski is unfastened (uncoupled), the greater the likelihood of injuries and injuries to the lower extremities.

"Dropping or uncoupling" a ski for the purposes of this patent application means mechanically separating a skier's leg from a sports apparatus. For the purposes of writing this application, it is assumed that a standard ski mount is a device in which a ski boot is attached. Historically, fixing the boot only in the front (cape) part, as well as attaching the boot to the ski with straps, is known. Currently, the most convenient and effective for alpine skiing is the mount, consisting of the front (cape) part and the rear (heel) part, containing the mechanism of closing and opening the mount. There are so-called freeride mounts, where the heel and toe of the ski mount are mounted on the ski, but do not have, with the help of ski, fastenings with each other (that is, are installed independently of each other), as well as the so-called mounts for skit, where the heel and toe are fixed on a platform swinging relative to the ski. The technical solution of this application is universal for any of these mounts.

The essence of the device according to this application is as follows.

The device for emergency (urgent) detachment of the ski consists of a base and a back stop, which are attached directly to the ski, a platform on which at least one part of the ski mount is mounted, and which has a groove or grooves for a pin or pins in the front and rear ends, which platform, with the rear end, joins with the rear stop, and with the front end, joins the base, where it is fixed (fixed) with a locking device that can be unlocked by the skier, whereby the platform can be separated from the ski. The locking device consists of a receiving module connected to the base, which is an enclosed electrical appliance capable of receiving radio signals, despite the fact that at least one pin comes out of the receiving module, which goes into the hole in the front end of the platform and thus fixes (attaches) it to the ski. The device is characterized in that at least one spring is installed between the receiving module and the base, which, after fixing (fixing) the receiving module in the closed position, is in a compressed state between the base and the receiving module, and when opening the latch made by the command of the receiving module, pushes the receiving module is forward (to the side opposite to the platform and the stop) and thus releases the platform from the pin (s) located in its grooves, after which the platform is easily separated from the ski.

For the purposes of this application, the terms “receiving module” and “capable of receiving radio signals module” are equivalent.

For the purposes of this application, a ski mount is understood to mean both a ski mount as a whole, consisting of several parts, and individual parts of a ski mount, namely: a front (cape) ski mount, a rear (heel) ski mount.

For the purposes of this application, the term "front" refers to what is directed towards the sharp (cape) end of the ski (or is located closer to it), and the term "rear" refers to what is directed to the blunt (heel) end of the ski (or is located closer to him).

The emphasis and base are designed to securely fix them on the ski, including through self-tapping screws, soldering, embedding, gluing, anchoring, etc. Together with the receiving module, for the purposes of this application, it is permissible to call the disconnecting unit or actuator.

The receiving module has at least one pin that, when the receiving module is moved to a fixed state, enters a hole in the front end of the platform. Between the receiving module and the base, springs (or a spring) are installed, which, when the latch is opened, push the receiving module forward (in the direction opposite to the platform and the stop). The locking mechanism opens (for example, under the action of a pyro-pusher, that is, a pyrotechnic element, in the particular case made on the basis of a pyro cartridge). Thus, the spring extrudes the pins from the end openings of the platform, and the platform is released.

In the particular case of the device: the receiving module contains a socket for a current source (power source, electric battery or several batteries).

In the particular case of the device: the receiving module contains a current source.

In the particular case of the device, two or more springs are installed between the receiving module and the base.

In the particular case of the device, the locking mechanism (the mechanism that opens the latch that holds the receiving module in a fixed state on the base) opens under the action of the pusher.

In the particular case of the device, a pin that exits the receiving module and enters the hole in the platform can pass through the hole in the base. In the particular case of the device in the platform there are more than one pin and more than one hole.

Any of the pins mentioned in this application can be made in the form of a strip, and also have a round, oval, square and rectangular shape in cross section, and also have a flat end, a conical end, a beveled end.

In the particular case, the pins in the section from the receiving module to the front end of the platform can be bent, including being made at right angles, to allow greater removal of the receiving module up from the base and from the ski. Accordingly, the pin may be L-shaped so that at one end it extends from the bottom of the receiving module and the other end enters the opening of the platform.

The emphasis is made in such a way that the platform placed in it with the rear end is limited in movement. In the particular case of the stop, the emphasis has at least one tenon, peg or pin, which is inserted into the counterpart on the platform. In this case, the use of two spikes, pegs or pins is optimal.

In the particular case of the device, the battery of the receiving module is removable, that is, capable of easily detaching from the receiving module and securing it back, which simplifies the replacement or recharging of the battery.

In the particular case of the device, the radio device of the receiving module is removable, that is, capable of being easily separated from the receiving module and secured to it again, which simplifies the replacement or storage of such a radio device. In the particular case of the device, the spring is worn on the pin of the receiving device.

A possible embodiment of the described device for emergency (urgent) ski cleavage with a special release mechanism for the lock (lock), arranged as follows.

As already mentioned, the device for emergency (urgent) detachment of the ski is different in that at least one spring is installed between the receiving module and the base, which, after fixing (fixing) the receiving module in the closed position, is in a compressed state between the base and the receiving module, and when the latch is opened, made by the command of the receiving module, pushes the receiving module forward (to the side opposite to the platform and the stop) and thus releases the platform from the pin located in its grooves (pcs ftov), whereupon the platform can be easily separated from the ski. The most optimal solution to the mechanism for opening the latch in such circumstances is a mechanism that opens under the action of a pyro-pusher, that is, a pyrotechnic element, in a particular case made on the basis of a squib.

Until the pyrotechnic element is activated, the latch remains closed, being pressed by an elastic element (latch spring), which does not allow it to move freely. In this case, the latch is engaged (engages) with the locking protrusion of the base. When triggered by a signal, the pyrotechnic element releases explosive energy directed towards the retainer, after which the retainer shifts toward the elastic element (retainer spring) and opens, that is, it reaches a position opposite the base recess and exits engagement with the locking protrusion of the base, after which the fixation of the spring-loaded receiving module disappears, which begins to move away from the platform.

So that the latch does not have time to return to its previous position before the receiving module moves, a latch stopper of the latch can be provided, which, under the action of the spring of the latch stopper, will enter the groove of the latch and will not allow it to return to the locked position (meshing with the protrusion of the base).

In a particular case, the device may additionally include a transmitting module (transmitting unit), with which a person (skier) initiates the separation of skis by pressing a special key (button). Such a unit contains a radio transmitting module, with the help of which a communication is made with the ski receiving module. The transmitting unit may contain the following buttons: activating disconnection, turning on the unit, and checking communication with the receiving module. The charge level and the on state of the device can be displayed by an LED. The disconnect activation button starts transmitting the radio signal from the transmitting unit of the transmitting unit to the receiving unit, after which the receiving unit opens the locking mechanism.

In the particular case of the device: the receiving device can be enclosed in a water-repellent housing equipped with devices for damping loads and vibrations (dampers).

In the particular case of the device: the receiving device further comprises a power button (activation toggle switch). In the particular case of the device: the receiving device further comprises light bulbs or LEDs signaling the strength (measure, magnitude, degree) of the charge of the current source.

In the particular case of the device: the power button (activation toggle switch) of the executive module can serve as an indicator of the charge strength of the current source.

In the particular case of the device: the receiving device contains a connector for recharging the current source.

In the particular case of the device: the connector for charging the current source is made according to the micro-USB standard.

In the particular case of the device: the receiving module is configured to receive signals via wireless communication such as "bluetooth", either wirelessly such as Wi-Fi, or by other wireless standards not specified above.

In the particular case of the device: the receiving module further comprises an indicator of the ability to receive signals wirelessly (communication indicator).

The device emergency (urgent) cleavage of the ski, mounted on the ski and brought into working position (the spring is compressed and fixed), operates according to the following scheme.

In an emergency, the receiving module receives a start (start) signal via radio, and then transmits a signal to open the spring retainer, which, when released, pushes the receiving device and its pins forward (to the side opposite to the platform and the stop), after which the platform, having lost fixing on one of the sides, can no longer be held only by contact with the stop and is completely detached from the ski. Thus, the ski mount fixed on the platform is separated from the ski, in which the ski shoes (boot) are located, and the skier gets rid of the skis that create the sailing effect, which would drag him deep into the avalanche mass.

The claimed technical solution allows for emergency, as fast as possible, uncoupling the ski when emergency release is required.

Thus, the claimed technical solution fully fulfills the task.

It is assumed that during the sale (turnover) of a product (device) on the free market, it will be just a single set (set) of at least the following structural elements:

- battery,

- a receiving module designed to be fixed on the base and containing a radio device,

- emphasis

- a platform designed to carry at least one ski mount and designed to be fixed between the emphasis and the base by means of at least one pin that exits the receiving module and enters an opening in the platform,

- a spring installed between the receiving module and the base, which spring, after fixing (fixing) on the base of the receiving module, is in a compressed state, and when opening the latch pushes the receiving module forward (to the side opposite to the platform and the stop).

In the future, the athlete or other person who is servicing the skis will be able to fix the proposed device on each ski that is not equipped with mounts, namely, fix the emphasis and base on the ski, fix the ski mount (or both ski mounts) on the platform, place the platform between the emphasis and base, set the receiving module in a fixed position on the base so that the pin (s) enter the receiving hole (s) of the platform.

The analysis of the prior art, including a search by patents and scientific and technical information and identification of sources containing information about analogues of the claimed technical solution, allowed us to establish that the applicant did not find sources characterized by signs that are identical or equivalent to all the essential features of the claimed invention, as well as obvious for a specialist in the specified field.

Therefore, the claimed technical solution meets the criteria of novelty, inventive step and industrial applicability.
