Definitions

  • the invention relates to a element for retaining a boot on a gliding board, in particular a ski. More specifically, the invention relates to the device for adjusting the longitudinal position of a retaining element on a ski.
  • each element has a jaw carried by a body which is movable under the effect of the stresses of the shoe against the return force of a spring housed in the body.
  • the body of the rear element is, in known manner, movable along a slide, and a lock makes it possible to position the body in a precise position adapted to the length of the shoe. From this position defined by the lock, the body can still slide backwards, when the boot is engaged and during flexing of the ski, against the restoring force of one or more springs called recoil springs. It also happens that the front retaining element has a body movable along a slide.
  • the recoil spring or springs determine the thrust that the retaining element applies to the boot, the front element forming a fixed stop on the ski.
  • the thrust depends on the longitudinal position of the body along the slide. An initial position that is too far back from the rear element gives too little thrust, resulting in loose support of the boot in the retaining elements, great imprecision in driving the ski, and a high risk of inadvertent triggering by premature release of the shoe. A too advanced initial position of the rear element makes it difficult to put on. The thrust is too strong and disturbs the correct functioning of the retaining elements.
  • the adjustment of the longitudinal position of the retaining elements, in particular of the rear element, is an important operation on which the proper functioning of the elements depends. Some experience is necessary to perform this operation, since it must be checked that the thrust is within a correct range of value. A ski specialist can carry out this operation without difficulty, but, as a general rule, the user of the skis is not able to carry out the adjustment himself, or else to find a good adjustment after an accidental displacement of the element. .
  • the lock which allows this longitudinal adjustment must be accessible and easy to maneuver. It is also necessary that once the lock in the open position, the body of the element can be easily manipulated to bring it into a new position. This is particularly important for skis used for rental where an adjustment is necessary for each new user.
  • the lock must be well protected to prevent it from accidentally opening, for example, during skiing, following blows from the other skiing during a fall, or coming from the skis of other skiers in the queues to the lifts. It is also necessary to prevent the lock from accidentally opening during transport and handling of the skis.
  • a lock, as described in German patent application DE 27 47 626 is easy to operate but poorly protected. In fact, given its dimensions and its orientation, the long operating tongue can be very easily accidentally lifted, for example when handling skis.
  • a lock as described in patent applications DE 30 15 478, and FR 2 451 756 is better protected insofar as it offers little grip outside the volume of the body.
  • the longitudinal adjustment requires the use of a tool. Its use for the specialist is therefore not simple.
  • a lock such as that described in patent application FR 2 672 506 offers a good compromise between good protection for the user and ease of operation for the specialist.
  • the body is easy to move for the specialist. Indeed, by placing for example the thumb on the body of the element, and raising the loop with the index finger, the specialist has a good grip for easily moving the body in its new position.
  • Such a lock is however complex to achieve on a mechanical level, because it requires several connecting parts to access the lock itself.
  • An object of the invention is to improve existing adjustment devices, and to produce a longitudinal adjustment device which gives a very good compromise between ease of manufacture for the manufacturer, accessibility and ease of handling for the specialist. , and protection against accidental opening for the user.
  • the invention proposes to achieve this object by extending the horizontal part of the lock by an operating member extending along the rear face of the body of the retaining element, and having the overall shape of a "T" , whose branches of the horizontal upper bar are designed to be lifted by two fingers of the hand.
  • the operating member is made of a flexible material.
  • the base of the operating member has a ramp oriented from bottom to top and from back to front.
  • Figure 1 is a perspective view of a rear retaining element equipped with the longitudinal adjustment device of the invention.
  • FIG. 2 shows in side view and in partial section the rear part of the retaining element of FIG. 1.
  • FIG. 3 is a front view of the operating member which equips the device of FIGS. 1 and 2.
  • FIG. 1 represents a rear retaining element 1.
  • the element has a jaw 2 carried by a body 3.
  • the jaw is movable around a transverse axis carried by the body, and its movement is controlled by a spring housed in the body.
  • the initial compression of the spring is adjustable by a plug 4 accessible on the rear face of the body. The plug is located about halfway up the body.
  • the jaw has two stable equilibrium positions, a low position for retaining the shoe, and a high position for releasing the shoe.
  • Figure 1 shows the retainer with the jaw in the up position.
  • a release lever 5 makes it possible to bring the jaw into the high position by voluntary action.
  • the lever 5 is articulated to the body in the vicinity of the axis of rotation of the jaw. According to Figure 1, when the jaw is in the high position, the heaving lever is lying on the rear part of the body. In this position, the rear end of the lever 5 extends a little beyond the body. This rear end preferably has a bowl 5a in which the end of the stick can be engaged, and a projecting rim 5b.
  • the body 3 is slidably mounted along a slide 6 which is intended to be secured to a ski.
  • the position of the body along the slide is defined by means of longitudinal adjustment.
  • the slide has an elevated central portion pierced with a plurality of orifices 8.
  • the body 3 has in its lower part, on the rear, a lock 9 provided with teeth 10 which are intended to engage in one or more openings adjacent to the slide.
  • the lock 9 is slidably mounted inside the body, and a recoil spring 12 housed in the rear part of the body pushes the lock into abutment towards the rear of the body.
  • the recoil spring 12 defines the thrust that the retaining element exerts on the shoe.
  • the recoil spring also ensures the return of the lock in its locked position, that is to say its low position where its teeth are engaged in orifices. From this position, the lock can be raised until the teeth are released from the holes in the slide.
  • the upper position of the lock it is not intended that the upper position of the lock be a stable position.
  • the invention could be applied to locks with two stable positions.
  • the bolt has an operating tongue 13 towards the rear.
  • the rear end of the tongue is extended upwards by an operating member 14.
  • the actuator 14 extends upward along the rear face of the body. Seen from the front, it generally has the shape of a "T”, with a central upright 15 and an upper transverse bar 16. The member is located substantially in line with the rear end of the heaving lever, when the lever is lying alongside the body.
  • the operating member is intended to be used in the following manner. Generally, the adjustment in the longitudinal position of the body is carried out while the jaw is in the open position, and the release lever is in the lying position. In addition, for such an adjustment, the specialist is used to presenting skis flat, facing him, with the tip on his left, and the heel on his right.
  • the lock can be brought into the low position very simply by placing the thumb in the middle of the crossbar 16, then by pushing down on this bar. This movement is also achievable in a very natural way.
  • the height dimension of the operating member is determined so that in the high position of the lock, the crossbar does not come to abut against the rear end of the lever and that it remains below.
  • the operating member has in its conditions a height close to half the height of the body.
  • the member has a central clearance 17 in the middle of the crossbar 16. This clearance is provided so that the plug 4 remains accessible.
  • the upright 15 has a substantially rectangular section, the largest dimension of which corresponds substantially to the width of the lock.
  • the crossbar has an approximately circular section, at least at the end of its branches.
  • the branches of the bar 16 extend on each side of the upright 15 over a distance corresponding approximately to half the width of the index or middle finger of a human being that is about 10 millimeters, and the branches are connected to the upright by a quarter-circle rib whose curvature is approximately that of the end of the index or middle finger.
  • These shapes and dimensions are intended to facilitate the grip of the operating member. However, they are not limitative for the invention, and any other suitable shape or dimension is suitable.
  • the operating member is flexible, that is to say it is made for example of deformable plastic, or elastomer.
  • the rigidity of the operating member is however sufficient for the operating member to stand upright by itself along the rear face of the body.
  • the lock is itself made of a rigid material taking into account its function, the operating member is assembled to the lock by any suitable means.
  • the member 14 is extended forward by a tongue 19 which passes under the rear end of the lock, and which is assembled to this end for example by screws or rivets. Any other means of mechanical assembly, by gluing or the like is also suitable.
  • the lock is metallic and the operating member is made of a vulcanizable elastomer, the operating member can be produced by counter-molding on the end of the lock. The assembly occurs by itself with the vulcanization of the elastomer.
  • the flexibility of the operating member makes the device and the body of the retaining element less sensitive to shocks. Indeed, in the event of impact, the operating member deforms and is pressed against the rear face of the body which it also protects. The operating member also absorbs each shock by its deformation.
  • the upright of the operating member has at its base an inclined ramp from bottom to top and from back to front. Thanks to this ramp, the shocks applied to the base of the operating member produce a downward component in the lock. This component opposes the opening of the lock. In addition, the deformation of the operating member under the effect of the shock increases the slope of the ramp 20 in the direction where eu prevents the opening of the latch.
  • the operating member which has just been described facilitates the operation of the lock. It also makes it safer insofar as the operation of the lock and the longitudinal movement of the body are easy and natural only if the ski is facing the manipulator, with the tip on the left and the heel on the right. In other cases, either the opening of the lock, or the movement of the body requires a significant voluntary effort.
  • the bolt is easily raised only if the two branches of the crossbar 16 are stressed simultaneously. If only one of the branches is gripped, the operating member responds with a deformation in the advantageous case where it is flexible.
  • the device which has just been described can be produced in a very simple manner. It does not require any particular arrangement of the body of the retaining element, apart from the lock itself, more precisely the rear end of the lock.
  • the lock itself is well protected against accidental opening, in particular because of its flexibility and the ramp that it presents at the base of the upright.
  • the present description is given for information only and other implementations of the invention could be adopted without departing from the scope thereof.
  • the invention is not limited to a rear retaining element. It could also apply to a front retaining element which would have a movable body along a slide. In this case, the device could be located on the front or on the side of the body.
