Description

The invention relates to a connecting device between the sole of a

  ski boot and ski, monoski or snowboard. New ski sports such as monoskiing or surfing have made it necessary to create adapted surf bindings. The first bindings were bindings adapted to this type of sport, but they came from classic bindings

downhill skiing or downhill skiing.

  The bindings were secured to the ski board or the surfboard, only the orientation of said bindings was different from the longitudinal axis of the boards

  compared to the orientation for classic skis.

  The fixings were arranged, of course, according to the user according to, if it has as a foot of call,

a left foot or a right foot.

  Currently, there are three trends for ski bindings to be adapted to monoski or ski surfing: independent triggering, synchronized triggering and

elastic fixation.

  The state of the art can be defined by the following patents: FR-A-2,627,097: each attachment comprises a plate provided with a central hole into which a central pivot integral with the snowboard engages. can rotate around the central pivot and be locked in an angular position chosen by sliders sliding in the slides of the central pivot and provided with notches engaging in notches

  cores formed at the periphery of the central platinum hole.

  Application to adjustable bindings for snowboarding.

  FR-A-2 626 189: the attachment comprises, for the blocking of the boot, a front caliper and a rear caliper with cam, pivotally mounted respectively on two sliders movable longitudinally on the same elongated plate adjusting screws with head of maneuver allow to modify the longitudinal position of each slider The plate is fixed, by its

  central part, on the ski or similar by means of screws.

  Applications: skiing, monoski, snowboarding.

  FR-A-2 649 329: this device is characterized in that the two movable jaws of the two front and rear attachment assemblies are coupled to each other and to a braking device mounted at the rear of the board. surfboard and having a movable spade articulated about an axis so as to automatically move the spade of the braking device into the active position in which it is planted in the snow as soon as one of the movable jaws moves as a result of the triggering

of one of the fasteners.

  FR-A-2651144: each foot of the user is keyed on the supports integral with the plate, itself secured to a cylindrical base fixed to the surf A collar, anchored at two points of the plate, encloses the foot to keep it on the supports When a fall of the user causes, in one or both collars, a tension higher than an adjustable value, the locks simultaneously release one of the anchoring points of the collars, thanks to the sheathed cables From when the front foot released, pulls on a belt that separates the abutment of the surf; the bent shaft, articulated in the center of the base pivots to bring the spade to the edge of the surf where it rotates in a vertical plane which drives it into the snow The device according to the invention is intended for the practice of the snowboarding and all sports requiring the binding of feet to the same element. FR-A-2651143: the present invention relates to a device for attaching a front shoe and a skier's rear boot to a snowboard, of the type in which these shoes are respectively held on the snowboard. surfboard by first and second fasteners, these two fasteners being provided with respective energy generating means and being coupled to each other by connecting means This attachment is characterized in that the force provided by the means for generating energy of the first fixation is determined by its energy generation means and by the energy generation means of the second fixation, the force supplied by the energy generation means of this second fixation being determined by his only means of

energy generation.

  FR-A-2 630 338: the fixing assembly according to the invention comprises a first attachment and a second attachment each provided with a plate retained by a fixed stop and a movable stop. The movable stops slide in their bases and are connected to each other. by a cable The release of one of the plates releases the mobile stop so that the cable also releases the second

movable stop and the second plate.

  This state of the art highlights the three trends

techniques mentioned above.

  The triggering in rotation and simultaneous causes

serious accidents.

  The current elastic fastening does not allow the loosening The current elastic fastening allows a damping of the shocks at the time of the falls by absorption of the efforts The main disadvantage mainly lies in the fact that there is no direct contact between the sole of the shoe and the ski board This drawback raises

  board control problems by the user.

  In summary: There are three types of snowboard binding: 1) the "plate" bindings, a single support element for the ski boot: BURTON, EFGEN, EMERY, MEYER, FIGL

(registered trademarks).

  2) the so-called "studs" fasteners, the ski boot is held by a front stop and a rear stop:

  EMERY, EFGEN, SNOWPRO (registered trademarks).

  3) the so-called "plastic shell" fasteners, the semi-rigid plastic shell system only allows the use of boots

  or après-ski: BURTON, DURET, LOOK (registered trademarks).

  The first observation is the most important: in the existing snowboard binding systems (with plate or studs) using ski boots, none has a flexibility of the entire binding in relation to the movements of the ski. sole of the ski boot (both lateral and rotational) existing snowboard binding systems (plate or stud) use rubber parts that are inserted

  between the binding and the sole of the shoe.

  The locking of the shoe on the binding completely crushes the canceling rubber, makes itself any lateral bending. The second finding: existing snowboard binding systems (plate or studs) do not dampen any bending and shock, hence many trauma and ligament problems in the

knees of surfers.

  The sole of the ski boot never follows the plane of the fixation of the surf o the problem of breakage for the elements

  constituting the fixation or even tearing of it.

  The device according to the invention is of the type using the elastic fastening while maintaining contact between the sole of the shoe and the surfboard or monoski; this device which serves platinum between the board and the binding allows to use the most effective ski bindings, said fasteners coming into place on the

connecting device.

  The device according to the invention may be entitled "device

  damped asymmetric bending connection ".

  For this purpose, the connecting device between the sole of a ski boot and the board of a ski, monoski or snowboard, is of the type using a support plate which is fixed to the board, said board can receive a abutment on which is mounted a connecting plate characterized in that said plate is provided with rubber elements ensuring the connections and damping, said stop is composed of an assembly element which is assembled on said plate support, a support head which receives holding pins ensuring the maintenance; said connecting plate, in its front part, is mounted inclined relative to the plane of the board, the part

  rear of said platen is provided with a removable damper.

  Said connecting plate consists of two asymmetrical parts; both parties are hulls that receive

  two axes of support and two axes of connection.

  The holding pins are embedded in the bending rubbers passing through two holes provided for this purpose in the head

support that makes up the stop.

  The holding pins are interchangeable depending on the use. The connecting pins stiffen the assembly of the connecting plate by crossing right through the two plastic shells, the front shell and the rear shell The end of the connecting pins allows complete locking of the stop and the

connecting plate by means of screws.

  The ends of the connecting pins allow the mounting of a fastening means of the ski boot on the connecting plate. Between the front shell and the connecting element, a screw of

  adjustment adjusts the inclination of the connection plate.

  The bending rubbers are four in number, two per support axis. They are arranged concentrically with the axes of

  holding on either side of the stop support head.

  The bending rubbers are interchangeable according to the

hardness wanted.

  According to another embodiment, the bonding rubbers are hollow beads which provide an elastic continuity between

  the front hull and the rear hull of the connecting plate.

  The rear shell is provided with a hole which makes it possible to set up a rubber damper. Said damper has a half-spherical shape extended by a cylindrical part which ends with another smaller semi-spherical shape. The rubber half-sphere, the largest, is in contact with the ski board or surf The other half rubber sphere protrudes from the upper face of the rear shell of the connecting plate,

  it is directly in contact with the sole of the shoe.
