Definitions

  • the invention relates to a device for retaining a shoe on a sports machine, which device comprises a reversible locking mechanism of an anchoring element of the boot.
  • Such a device is used in areas such as skiing, particularly cross-country skiing, hiking, or telemark, snowshoeing, skiing or rollerblading, or the like.
  • a reversible locking mechanism which comprises a housing which carries a fixed jaw, a base, and a drawer which carries a movable jaw.
  • the slide can slide in the housing in a direction of approximation or in a direction of relative distance of the jaws, the sliding being obtained in part at least by action on a lever of the mechanism.
  • the invention generally aims to improve a retaining device which comprises a reversible locking mechanism of an anchoring element of a boot. More specifically, an object of the invention is to simplify the structure of the locking mechanism. Another aim is to reduce the assembly time of the component parts of the mechanism. One more goal is to reduce the manufacturing cost of the mechanism.
  • the invention proposes a device for retaining a boot on a sports machine, the device comprising a reversible locking mechanism of an anchoring element of the boot, the mechanism comprising a casing which carries a fixed jaw. , a base, and a drawer which carries a movable jaw, the slide slidable in the housing in a direction of approach or in a direction of relative distance from the jaws, the mechanism further comprising a lever.
  • the lever has a cam surface, the lever being secured by a hinge to one of the parts that are the housing and the drawer, the other of the parts having a bearing surface, the cam surfaces and bearing cooperating so that, when in contact with each other, the jaws are brought closer to each other if the lever is in a locking position, and the jaws are moved away from one another other if the lever is in an unlock position.
  • the retaining device according to the invention is characterized in that the mechanism comprises an elastic means adapted to bias the slide so as to cause the relative movement of the movable jaw with respect to the fixed jaw.
  • the arrangement of the locking mechanism organizes a cooperation between the position of the lever and the position of the drawer. This cooperation is done by contact between the cam surface of the lever and the bearing surface connected to either the housing or the drawer. The contact is direct, which is to say that it is done without recourse to other moving parts.
  • a first advantage generated by the invention is that of simplicity, not only as regards the structure of the locking mechanism, but also with regard to its use. Indeed, the relative friction of the cam and bearing surfaces faithfully informs the user about the state of the mechanism, that is to say on the position of the movable jaw, because the lock-related efforts are transmitted directly. between the lever and the drawer by the interaction of cam and support surfaces.
  • the first embodiment which will be described below relates more particularly to a device for retaining a boot on a cross-country ski, or telemark.
  • the invention applies to other fields, such as those mentioned before.
  • a retaining device 1 is provided for reversibly retaining a shoe 2 on a cross-country ski 3.
  • the shoe 2 is represented in part only, in phantom. It will be noted that it comprises an anchoring element 4, made for example by means of a rigid wire of circular section, oriented transversely and parallel to the soleing 5.
  • ski 3 is shown partially and stylized. It is well known to those skilled in the art.
  • the retaining device 1 comprises a first reversible locking mechanism 6 of the anchoring element 4 of the shoe 2. The operation of the mechanism 6 will be discussed later.
  • the retaining device 1 comprises, as shown in the figures, only the first reversible locking mechanism 6.
  • the device 1 may also include a second mechanism, not shown, which may also be a reversible locking mechanism, an elastic return mechanism, or a mechanism that provides both the locking and return functions.
  • the second mechanism cooperates in this case with another anchoring element of the shoe, located further back than that 4 used to cooperate with the first reversible locking mechanism 6.
  • the device 1 may further comprise one or more longitudinal guide edges of the sole assembly 5.
  • the first locking mechanism 6, called simply reversible locking mechanism 6, comprises in particular a casing 11, which carries a fixed jaw 12, a base 13, and a drawer 14, which carries a movable jaw 15. It will be seen later how these elements 11, 12, 13, 14 and 15 are structured and how they work.
  • the retaining device 1, here in fact the locking mechanism 6, further comprises a lever 16.
  • the latter serves to lock or unlock the mechanism, for example by an external action such as a manual action.
  • an external action such as a manual action.
  • the structure and operation of the lever 16 will be deepened afterwards.
  • the lever 16 has a cam surface 21, the lever 16 being secured by a hinge 22 to one of the parts that are the housing 11 and the slide 14, the other of the parts 11, 14 having a bearing surface 23, the cam surfaces 21 and support 23 cooperating so that, when in contact with each other, the fixed jaws 12 and movable 15 are moved towards each other if the lever 16 is in a locking position, and the fixed and movable jaws 12 are moved away from each other if the lever 16 is in an unlocked position.
  • the lever 16 acts directly on the housing 11 or on the slide 14 by contacting the cam surfaces 21 and support 23. This direct action allows the user to properly perceive the position of the drawer, and therefore the movable jaw 15 when the lever 16 is manipulated. Moreover, because of the simplicity of its structure, the locking mechanism 6 faithfully transmits driving pulses, or sensory information, between the boot 2 and the ski 3.
  • the housing 11 delimits a longitudinal cavity 24.
  • the casing 11 comprises a first lateral wall 25 opposite a second lateral wall 26, which 25, 26 are connected to one another by a top 27 and a wall 28.
  • the walls 25, 26, 28 and the top 27 form here a single piece.
  • a cover 29 delimits the cavity 24 opposite the top 27. It is noted that the latter 27 is provided to be opposite the shoe 2, and that the lid 29 is facing the ski 3 .
  • the housing 11 is secured to the base 13, by the side walls 25, 26 and rear 28.
  • the base 13 and the housing 11 form a single piece.
  • the cover 29 is parallel to the base 13, and for example located in the same plane as the latter 13.
  • the base 13 is formed as a plate which extends to the base of the housing 11 , especially towards the front, that is to say in a direction away from the rear wall 28, but also on the sides.
  • the slide 14, housed in the housing 11, is movable in translation parallel to the base 13. Since the latter 13 is provided to bear on the ski 3, directly or indirectly, the slide 14 is itself movable in translation in the direction of the length of the ski 3. It follows that the jaw 15 is movable in translation, parallel to the base 13, in the direction of the length of the ski 3, when the mechanism 6 is mounted on the latter 3. This promotes cooperation with the transverse anchoring element 4 of the shoe 2.
  • the lever 16 is secured to the slide 14. As a result the lever 16 follows the movements of the slide 14, both in a locking direction and in an unlocking direction.
  • the lever 16 extends in length between a hinge end 33 and a free end 34.
  • the hinge 22 secures the hinge end 33 of the lever 16 to the drawer 14.
  • the hinge 22 comprises for example a journal which extends along an axis 35.
  • the free end 34 for its part, is intended to be manipulated by the user, as will be seen later.
  • the axis 35 of the articulation 22 of the lever 16 is parallel to the base 13. This allows the manipulation of the free end 34 in a direction of removal or in a direction of approximation of the base 13 is that is to say also, by cause-effect relationship, ski 3. This manipulation has the advantage of being simple to achieve.
  • the axis 35 of the hinge 22 of the lever 16 is perpendicular to the direction of movement of the slide 14 in the housing 11. It follows that the lever 16 pivots in a plane perpendicular to the base 13 or the ski 3. The lever 16 thus remains above the base 13 and the ski, which gatantit the absence of interference by contact with another retaining device used for the second foot, or with any other obstacle. The use of the device 1 is therefore easier.
  • the cam surface 21 of the lever 16 has a convex portion 41 formed of a series of lines juxtaposed and parallel to the axis 35 of the joint 22. It will be seen later that the orientation of the surface 21 allows the lever 16 to bias the slide 14 by efforts oriented in the direction of movement thereof 14. This optimizes the efficiency of the locking mechanism 6, reducing as much as possible the efforts to provide to obtain the lock.
  • a stop 42 is integral with the housing 11, the abutment 42 having the bearing surface 23 intended to cooperate with the cam surface 21 of the lever 16. More precisely here the stop 42 is secured to the base 13, which is secured to the housing 11. In other words the stop 42 is integral with the housing 11 through the base 13. The stop 42 is indirectly secured to the housing 11. The use of a stop 42 allows to choose the best point of support for the lever 16, as will be understood in the following description.
  • the stop 42 is disposed on the base 13 so that the hinge 22 of the lever 16 is located between it 42 and the slide 14.
  • the bearing surface 23 of the stop 42 intended to cooperate with the cam surface 21 of the lever 16, is in the path of the slide 14. This surface 23 is therefore in the extension of the longitudinal cavity 24. This allows to urge the slide 14 in its direction of movement in the housing 11.
  • the bearing surface 23 of the abutment 42 has a flat shape.
  • the bearing surface 23 forms with the base 13 an angle ⁇ whose value is between 60 and 90 °, knowing that angle values of 75 to 85 ° gave good results.
  • the bearing surface 23 is inclined, with respect to the base 13, so that its top 43 is closer to the housing 11 than its base 44. It will be seen later that this inclination gives stability to the locking situation mechanism 6.
  • the stop 42 forms with the base 13 a single piece. Finally, the housing 11, the base 13 and the stop 42 form a single piece. This saves time in manufacturing. It may alternatively be provided that the stop 42 is an insert on the base.
  • the shoe 2 is approached from the retaining device 1 so that the anchoring element 4 is above the space between the fixed jaws 12 and mobile 15.
  • the space has its maximum volume because the jaws 12, 15 are spaced apart from each other, which is possible because the lever 16 is in an unlocked position. This position is obtained when the free end 34 is at the maximum distance from the base 13.
  • the anchoring element 4 is located between the jaws 12, 15.
  • the locking operation consists in pivoting the lever 16, according to the articulation 22, to approach the free end 34 towards the base 13.
  • the cam surface 21 is supported on the bearing surface 23 of the stop 42 to push the slide 14 in a direction away from the stop 42, or also in a direction of approximation of the wall rear 28 of the housing 11.
  • the rotation of the lever 16 in a locking direction causes the relative approximation of the movable jaws 15 and fixed 12.
  • the retaining device 1, and more precisely the locking mechanism 6, is structured to oppose the unlocking in case driving stresses tend to move the jaws 12, 15 away from each other.
  • the locking mechanism 6 opposes the opening of the jaws, proportionally to the forces applied to them.
  • the locking mechanism 6 according to the invention operates here according to the principle of the toggle joint. Indeed, the arrangement of the point of contact 45 with respect to the hinge pin 22 makes it possible to generate a torque tending to press the lever 16 against the base 13, that is to say to maintain the lever in the locking position, when moving the slide 14, and therefore the axis 22, forwards.
  • an elastic means 51 urges the slide 14 in a direction of relative distance from the fixed jaws 12 and mobile 15.
  • the bias is towards the stop 42
  • the elastic means 51 facilitates the spacing of the jaws 12, 15, and consequently the release of the anchoring element 4, when the user returns the lever 16 to the unlocking position, as on the figure 3 .
  • the elastic means 51 makes it possible to maintain the contact between the cam surface 21 and the bearing surface 23, which provides stability and good operation of the locking mechanism 6.
  • the resilient means 51 urges the drawer 14 so as to to oppose the initial movement of the slide generated during the transition from the locking position to the unlocking position or vice versa.
  • the elastic means 51 is a spring.
  • it is a helical spring, housed in the housing 11, between the slide 14 and the rear wall 28, the spring is compressed when the mechanism 6 is in a locking position with the jaws 12, 15 close together. one of the other.
  • This arrangement is simple and easy to achieve. It can of course be provided any other structure for the elastic means, such as a wedge of elastomeric material, or other.
  • the bearing surface 23 is a single surface, in the sense that it is the only surface provided to cooperate with the cam surface 21, in a closing direction of the jaws. In other words, the bearing surface 23 is provided to the exclusion of any other surface that could have been used for the lever to request opening. This simplifies the structure of the locking mechanism 6, and therefore of the retaining device 1.
  • the slide 14 carries a stop 52 resiliently deformable in a reversible manner the stop being shaped to make contact with a front portion 53 of the shoe 2.
  • the idea is to remove the mechanical clearances between the front 53 and the locking mechanism 6, that is why the stop 52 is dimensioned to be slightly compressed between the front 53 and the mechanism 6 when the boot 2 is retained.
  • the movable jaw 15 has a concave shape.
  • this jaw can accommodate the anchoring element 4, so that the latter is retained on the principle of an obstacle connection, as opposed to a friction bond. This ensures a reliable hold.
  • the concave shape is here semicircular, to better marry the anchoring element 4, whose cross section is circular.
  • the fixed jaw 12 in turn, has a flat shape. This allows him easy cooperation with the movable jaw 15, for the retention of the anchoring element 4. And this also serves as a guide for the establishment of the anchoring element 4 between the jaws 12, 15.
  • the stop 62 is constituted by a folded tab, consisting for example of metal.
  • the stop 62 is an insert on the base, secured thereto 13 by any means. It can be a permanent means, such as gluing, riveting or other, or a removable means, such as a screw, a shape that allows nesting, or other.
  • bearing surface 23 of the stop 62 intended to cooperate with the cam surface 21 of the lever 16, has a concave portion 63. This facilitates the maintenance of the lever 16 in a stable locking position.
  • a retaining device 1 with a locking mechanism 6 This comprises a casing 11, a base 13, a slide 74 and a lever 76.
  • the lever 16 is secured to the housing 11. More precisely the lever 16 is connected to a support 77, by a hinge 78. The support 77 is itself secured to the base 13, which itself is secured to the housing 11, as seen for the first form. Finally, according to the third form, the lever 16 is connected indirectly to the housing 11, by the hinge 78. We are here in an inverse organization to those of the first and second forms, but for a similar operation.
  • the invention also covers an inverted locking mechanism 6, that is to say a mechanism favoring a locking position.
  • the resilient means 51 urges the drawer in a direction of relative approximation of the fixed jaws 12 and movable 15.
  • the first stable position is the locking position.
  • the lever When acting on the lever, it causes the movement of the drawer to move the jaws away from each other.
  • This displacement is obtained by a solution similar to the previous solutions, thanks to the cooperation of a cam surface with a bearing surface.
  • the drawer is more stressed by the elastic means 51 than in the previous embodiments.
  • This variant makes it less possible to solicit the mechanism. Indeed, the retainer is most often in the locking position.
  • the elastic means is less constrained, it requires less other elements of the device.
  • the elastic means 51 can therefore urge the drawer in a direction of relative distance from the fixed jaws 12 and movable 15, as is the case in the first three embodiments. However, it can also urge the drawer in a direction of relative approximation of the fixed jaws 12 and movable 15, as is the case in the fourth embodiment.
  • the elastic means 51 is thus able to urge the drawer so as to cause the relative movement of the movable jaw 15 relative to the fixed jaw 12.
  • the elastic means acts on the drawer when it is stressed, for example when a compression spring is compressed.
