Definitions

  • the invention relates to a set for retaining a shoe on a sliding board, including alpine skiing.
  • retainers that release the shoe when the stresses between the shoe and the board exceed a predetermined threshold.
  • Patent applications FR 2 351 678 and FR 2 374 922 describe a collection system and electronic processing of efforts.
  • Patent application EP 396 414 describes a electromagnetic type trigger
  • patent application FR 2 398 719 a pyrotechnic type trigger.
  • electromechanical triggering requires a significant source of energy to supply sufficient energy to the electromagnet which controls the opening of the jaw.
  • electromagnet which controls the opening of the jaw.
  • it is difficult to control the discharge phenomena of the battery over time.
  • a pyrotechnic type trigger is capable of providing instant energy important, however the number of possible trips before recharging the system is quite limited.
  • the invention provides a set for retaining a shoe on a board slide comprising a trigger block having at least one retaining jaw of a shoe attachment member, the jaw being movable between a closed position where it retains said attachment member and an open position where it releases the member attachment, the jaw being held in the closed position by a movable lock.
  • the assembly is characterized by the fact that the movement of the bolt is controlled by a source pneumatic energy to the exclusion of all other energy.
  • FIG. 1 represents the central portion 1 of a ski surmounted by a boot 2.
  • the boot is retained on the ski by its two rear and front end caps which are retained by rear and front retainers 3 and 4.
  • the rear retaining element 3 comprises a block of rear retainer 6 articulated with respect to a stirrup 7.
  • the stirrup is mounted tilting with respect to a rear support plate for the rear part of the shoe.
  • the rear plate is fixed in solidarity with the ski by any suitable means and for example by screws, by bonding or welding.
  • the rear retaining block 6 has a shoe retaining jaw 8 and a lever maneuver 9 secured to the block to force the jaw to tilt between a retaining position of the rear shoe toe and a position for releasing this tip.
  • the retaining block is in the shoe retaining position.
  • this rear element is not limiting and other modes of construction may be suitable.
  • the rear retaining block which is not releasable here could be replaced by a releasable element ensuring the release of the shoe beyond a constraint threshold determined.
  • the front retainer includes a front retainer 11 which will now be described and a processing circuit to be described later.
  • the front retaining block includes a lower plate 12.
  • the plate 12 On the rear, the plate 12 has a shoe support plate 14.
  • the plate 14 does not have no particular construction constraint. In particular, it is not necessary to provide an anti-friction material on the upper surface of the plate. Also we have less than construction and material constraint at the level of the shoe.
  • a jaw 15 retaining the front end of the shoe is articulated to the platinum.
  • the jaw is here a monobloc element comprising two lateral wings 16 and 17 of lateral retention of the shoe, and a sole clamp 18 for vertical retention. Restraint front of the shoe is made by the lower part of the jaw in contact with the sole or by the central part of the sole clamp in contact with the upper of the shoe.
  • the base of the jaw is articulated to the plate 12 around a transverse axis 20 and horizontal.
  • the base of the jaw has a width reduced, and the plate comprises a well 22 in which is engaged the base of the jaw.
  • the axis 20 connects the base of the jaw to the lateral edges of the well.
  • the dimensions of the well in the longitudinal direction are determined for allow the jaw to pivot freely between a retaining position where the jaw is standing vertically, the jaw is shown in this position in FIGS. 1 and 3, and a release position where the jaw is tilted on the front, Figures 2 and 6 illustrate this position.
  • stops limit the tilting of the jaw beyond of each of these two positions. These stops are for example the longitudinal edges of Wells. Any other stop may also be suitable.
  • the axis 20 is located in the front part of the jaw, in front of the wings and the sole clamp. Also the lateral trailing edges of the wings and the departure of the sole clamp are inclined. In this way when releasing the jaw, a lateral or vertical stress on the shoe tends to tip the jaw into its open position.
  • a spring can be provided, for example a torsion spring mounted on the axis 20. Such a spring is not visible in the figures.
  • a rocker 25 with two branches controls the opening of the jaw in the manner of a lock.
  • the rocker is articulated around a transverse axis 26 carried by the body 27 of the block trigger.
  • the rocker retains the jaw by its upper branch 28.
  • the branch is oriented in such a way that the support of the jaw generates a force component which passes through the axis 26 so that the rocker works like a lock.
  • the length of the branch 28 is determined for lock the jaw in its upright restraint position preventing it from tipping over forward.
  • the branch 28 is tilted upwards around its axis 26 as shown in figure 5.
  • the jaw thus released has the possibility of tilting towards the front by engaging under the branch 28 as shown in FIG. 6.
  • the end of the branch 28 carries a contact roller with the jaw.
  • the rocker is resiliently returned to its jaw retaining position by a torsion spring 30 which is located at the axis 26, and it is held in this position by a stop which for example comes from the body 27.
  • the movement of the rocker 25 in its jaw release position is itself controlled by a pneumatic cylinder 38, the rod 39 of which is intended to come into contact with the lower branch 35 of the rocker.
  • the body of the pneumatic cylinder 38 is fixedly attached to the plate 12. Its rod is movable between a retracted position illustrated in Figure 3 and an extended position illustrated in Figure 5. In the retracted position the rod exerts no action on the rocker 25 which is itself in the jaw retaining position under the action of the return spring 30. In the position output the rod 39 pushes the branch 35 to tilt the rocker 25 in its position release.
  • the cylinder preferably has an internal spring which recalls the rod in position September.
  • the solenoid valve is connected to a reservoir 42 which contains a gas under pressure by example of air or any other suitable gas.
  • This tank can be filled with gas under pressure via a nozzle 43.
  • the trigger block works as follows. At the engagement of the shoe, the jaw is held in the retaining position by the rocker, the skier engages the boot in the front jaw and immobilizes the boot on the ski using the rear retainer 6.
  • the trigger block could be adopted for the trigger block.
  • a gas cartridge connected to a regulator 51 instead of tank 42.
  • the cartridge contains gas under high pressure, and the regulator delivers low pressure gas to the solenoid valve and to the cylinder. Furthermore this pressure is constant, so that the pressure in the cartridge decreases gradually triggers does not affect trigger conditions. When the pressure of the cartridge drops below a determined value, it is exchanged with a cartridge new.
  • the cartridge 50 can be of the same type as the gas cartridges used for the recreational firearms, fire extinguishers or tire inflating bombs.
  • the electrical impulse which controls the opening of the jaw is delivered by a module 52 analysis and treatment of the constraints between the boot and the ski.
  • This module is shown schematically in Figure 8.
  • strain sensor 53 which delivers one or more signals related to the stresses between the boot and the ski.
  • This sensor is formed for example by a set of strain gauges arranged on a wafer in an arrangement suitable for react to the constraints between the boot and the ski.
  • FIG. 9 illustrates a method of mounting the strain gauges.
  • the sensor is located disposed on a plate 54 for supporting the trigger block.
  • the plate includes a first part in the shape of "U" which is intended to be fixed in solidarity with the ski by any appropriate means, for example screws.
  • a second part 56 in the shape of a "T" is connected to the base 57 of the first part, with a middle branch 58 engaged between the two lateral branches 55 of the first part, and an upper transverse branch which supports in particular the area of the retaining block on which the shoe rests.
  • the retaining block is integrally connected to this second part by any appropriate means, including screws.
  • the second part is kept raised relative to the upper surface of the ski.
  • a wedge 60 in the shape of a "U” is placed under the first part of plate 54.
  • the sensor 53 is located at the base of the middle branch 58 which is an area of bending in which the deformations of the plate appear resulting from the stresses exerted by the shoe on the ski.
  • strain gauges are arranged on their plate so as to react to these different constraints.
  • the wedge 60 and the plate could be in one piece or any other means could be suitable to keep the second part 56 raised "T".
  • the sensor 53 is connected to a processing circuit 54. This circuit analyzes the signals from of sensor 53 and compares them to a trigger threshold. When the trigger threshold is reached, the processing circuit sends to the solenoid valve 40 for a determined period a trigger signal which causes the cylinder 38 to exit.
  • the signal from the sensors is processed in any suitable manner.
  • processing can involve parameters such as signal strength and duration as described in patent application FR 2 363 343, or also FR 2 351 678 in the name of the applicant.
  • Other signal processing modes may also be suitable.
  • the processing circuit requires a source of electrical power.
  • the consumption of the treatment circuit is relatively small, therefore it is sufficient to use a small battery.
  • the energy that drives the trigger block is pneumatic, excluding another source, especially electrical or mechanical. This pneumatic energy has the advantage of being able provide significant power at low volume and weight.
  • the trigger block instead of the trigger block retaining the front of the shoe, it would be possible to place it on the back, or to place a block on the front and a block on the rear.
  • the jaw could retain other fastening members of the shoe than its front and rear end caps. It could for example be studs projecting from to the shoe sole, or a plate attached to the shoe sole, or any other appropriate means.
  • the mode of operation of the actuator and of the solenoid valve In other words, the cylinder is kept in the retracted position by the gas under pressure. In case of release of the shoe the solenoid valve lets out the gas, and the rod of the jack is sent to the extended position under the action of its return spring.
  • the invention is not limited to alpine skiing, it applies to all gliding devices or rolling where the shoe is releasably retained on the machine.
