FR2880815A1 - Shoe locking device for snowboard, has inclinable plate mounted on base fixed to snowboard, and connecting rod system closer to rear stirrup, by tilting shoe from front part towards rear part of plate, until shoe is integrated on plate - Google Patents

Abstract

The device has an inclinable plate (2) mounted on a base (1) that is integrated to a snowboard. The plate is connected to the base by an axle which allows the plate to pivot. Front and rear stirrups (3, 4) are mounted respectively on front and rear parts of the plate. A connecting rod system (5) is closer to the stirrup (4), by tilting a shoe fixed at the front part towards the rear part, until the shoe is integrated on the plate.

Description

The present invention relates to a device for locking

  shoes to snowboards.

  Locking is currently done through a system requiring the action of the hand or by a mechanical system. Current mechanical systems require either an adapter mounted on the shoe, or represent an outgrowth on the back of the shoe; which decreases the possibilities of inclination when cornering.

  The first system (requiring the adaptation of the shoe) locks the shoe in a slider which decreases the lateral flexibility with respect to the use of the conventional manual locking fastener.

  The classic attachment has a protrusion at the front of the shoe (buckle on stirrup).

  The device of the invention allows to block the shoe without the hand, without protruding front or rear of the shoe and allows to maintain flexibility identical to the conventional fixation and does not require any adaptation of the shoe.

  This device is intended for all types of use, in addition to the competition. The invention is characterized by a base (1) which is secured to the snowboard by screws. On this base is mounted a plate (2) which is connected to the base by an axis (12) which allows it to rotate. It is on the front of this plate that one fixes the front bow (3) of the fixation. While on the rear part of this plate is mounted a stirrup (4) which is movable. The movement of the stirrup is achieved by a system of rods (5) fixed on one side to the base, on the other, a carriage (6) which slides around the plate. On this carriage is mounted the assembly comprising the rear caliper (4).

  Thus by presenting the shoe in the front caliper, the plate will tilt, which will push back the rear caliper. This action will allow the positioning of the shoe on the plate and, by a pressure of the heel, the operator will reposition the tray to the horizontal, which will bring the rear caliper up to tighten the shoe (tightening the shoe on the tray). The locking of this position will be performed when the two housings provided for this purpose (lugs) will be reached.

  Unlocking requires the intervention of the hand to release the lugs (7) from their housing and thus allow the tray to switch again and release the rear caliper. This is done by pulling on the rings (8). The front caliper on the platform and the rear caliper on the trolley have several mounting locations to match different sizes and types of shoes.

  The clamping tension of the device is made adjustable by changing the distance between the upper link of the rod and the rear caliper. By changing it by action on a thread (9), it increases or decreases the stroke of the rear caliper and therefore the tension of the shoe lock on the fastener.
