FR2823985A1 - Electronic ski binding has remote control with motor release - Google Patents

Abstract

An electronic ski binding release has a remote control unit with receiver (3) controlling a motor (2) that releases the latch (1) releasing the ski boot when commanded automatically or by pressing a button.

Description

). The present invention relates to an electronic device for

  the opening of ski or snowboard bindings to allow the release of the skier / surfer's boot. The ski / surf bindings are traditionally opened mechanically during an impact (fall of the skier / surfer). You can also open them

  maouelle. The opening sensitivity of certain fasteners is adjustable.

  The disadvantage of the usual devices is that the fasteners only open when there is a shock or a force greater than the settings of the fxation. What has

  effect of causing injuries very often when skiers / surfers fall.

  The device according to the invention overcomes these drawbacks. According to a first characteristic, it in fact comprises a remote control unit which can trigger the opening of the ski / snowboard bindings automatically as soon as the skier / surfer begins to fall. You can also trigger the opening of

  fixings by a button placed on the remote control.

  According to particular embodiments: - the remote control unit (9) can be placed on the skier / surfer, on the skis, on the

  surf, or at a distance from one or the other.

  - the device is designed to reset automatically (13).

  - photovoltaic cells can be added for recharging

accumulators.

  - The device can be mounted alone or coupled with existing fixings (8).

  - the device can be installed either at the back of the shoe, in the middle, at

  the front or on a surfboard binding.

  - a specific module can be incorporated into the receiver (3) on each ski to know their positions one by contribution to the other, and if necessary to order

opening fasteners.

  - a sound and light device can be installed on skis / snowboards (3) and on the remote control (9) in order to find the equipment in the snow or as a theft prevention. The device can be triggered by a button (1 1) or by moving away from the

  remote control with respect to skis / surf.

  - the antenna of the remote control and receivers can be external or internal to the device - the opening and release device can be realized according to several modes of

  realization without the basic principle being changed.

  - The device according to the invention can be equipped with electronic sensors of the type:

  temperature, speed, shock, tilt, movement, vibration.

  -2 - the frequencies used for the links between the remote control and the receivers are

  chosen according to the manufacturing methods or uses.

  - the remote control like the receivers can be equipped with LCD screens (12) (liquid crystals) and microprocessors as well as computer programs allowing the configuration of the device and the support of the various sensors and

other devices.

  - springs (7), gas cartridges, electric motors (2) or electromechanical and explosives can be added to facilitate the ejection of the shoes or

opening the device.

  The electrical and electronic devices used for carrying out this invention

  are common and commercially available.

  The accompanying drawings illustrate the invention:

  Figure 1 shows in section, the device of the invention in the "closed" position.

  2 shows in section, the device of the invention in the "open" position.

  Figure 3 shows the front of the remote control.

  With reference to these drawings, the device comprises a remote control unit (9) fitted inside an electronic device allowing communication (on a given frequency) with the receivers (3). The remote control also has a battery or an accumulator for the operation of the device, a switch (10) allows the triggering of the receiver (3) placed at the back of the fations, a selection key (11) gives access to the computer program of the remote control and allows the selection of the various functions as well as the starting and stopping of the device,

  an lcd screen (12) allows the user to view the functions of the device.

  By actuating the switch (10) or by tilting the remote control, you give the order to a box (3) in which there is an electronic device allowing to receive information from the remote control. The electric device makes it possible to control electric motors and sensors, the housing (3) called receiver has a battery or an accumulator and an antenna for the operation of the device. Once the information has been received, the receiver (3) activates the electric motor (2) which, by a rotational movement, pivots up a latch (1) the latch is in the form of a hook, it has a straight part and a part smaller cubit at 90 forming a rim, the flap (4) is housed in the rim. The latch (1) in the "closed" position retains the flap (4). Which is pushed out by the central part of the fixing (6). Once the fixing "closed", the latch (1) by lifting by the action of the motor (2) releases the flap (4) which under the pressure of the part (6) opens by lowering. The fixing (8) ends up with a part (6) which has moved and which is no longer under pressure. The binding (8) can then be opened easily under the action of the

spring (7).

  i -3 On the final opening phase the part (6) returns to position and the flap (4) goes back up to lodge in the edge of the latch (1) thanks to the spring (5) the part (13) provides the connection

  between the head (14) of the binding and the part (6) for resetting.

  The spring (7) can be replaced by other devices as described in the chapter "particular embodiments" for faster ejection. By way of nonlimiting example, the casing of the remote control will have dimensions of the order of 5 cm for the length, a width of 4.5 cm, and a thickness of 2 cm. A receiver will have dimensions of the order of 4 cm in height and 4 cm in width

for a length of 5 cm.

  The device according to the invention is particularly intended for opening the fasteners

of skis and surf.
