    [0001] FIELD OF THE INVENTION The invention relates to a locking device for a wire element such as a strap, a rope, a cord, a lace, etc. STATE OF THE ART In the field of sport, and in particular that of mountain sports, it is important to be able to safely and effectively block one or more wire elements such as ropes, cords or straps. This is for example very important for climbing and mountaineering helmets. Adjusting the position of the neck and neck straps in relation to the head circumference must be properly performed to ensure that the helmet is fully effective in the event of an impact. The protective helmet described in the document EP 558427 in the name of the applicant relates to a helmet whose adjustment is made by two internal wheels that mesh with racks of racks provided in the headband and the neckband. The knobs protrude partially under the side edge of each side of the cap. One of the knobs is used for the adjustment of the headband, and the other for the neckband. In the patent application EP 2138061 also in the name of the applicant, the protective helmet comprises a neckband adjustable by means of two movable slides through a slot of the cap. These two slides meshes with two integral racks of the neck-band. In these two examples of the prior art, the adjustment is accurate and efficient but must be done by the user and requires learning. The disadvantage is that in the context of community use, it is difficult for the supervisor to adjust the helmets instead of the user.
    [0002] In the field of tightening shoe laces, patent application EP 0629793 A1 discloses a lace locking device comprising a body, a locking member and a maneuvering cap with two elastic tongues. The locking member is positioned in a body cavity, and the maneuvering cap is positioned above the body.
    [0003] The locking member and the maneuvering cap are integral, so that a movement of the maneuvering cap causes a displacement of the locking member. In the absence of external force, the elastic tongues push the actuating cover and therefore the locking member in a position such that the laces are wedged between the wall of the body and the locking member.
    [0004] To tighten the laces, the user must stretch the laces and translate the locking device by pushing on the body. Conversely, to loosen the laces, the user must pull the maneuvering cover to place the locking member out of the jamming position.
    [0005] The use of this device is relatively intuitive for tightening shoe laces because the user can see what he is doing. On the other hand, the use of this device to adjust a helmet headband is complex because the user must make the adjustments without seeing what he is doing.30 There is therefore a need to provide the helmets with blocking devices that are intuitive and easy to use, especially in the context of community use, where users are unfamiliar with this type of equipment.
    [0006] OBJECT OF THE INVENTION An object of the invention is to provide a device for locking at least one wire element that is reliable and easy to adjust. For this purpose, the locking device comprises at least one locking member intended to block at least one of the wire elements by wedging, a body provided with a cavity configured to allow the passage of at least one of the wire elements. and housing at least one of the locking members so that at least one of the locking members is movable in translation in the cavity along a first axis to a wedging position of at least one of the wire elements , a maneuvering cover, movable in translation along the first axis relative to the body and configured to allow the displacement of the locking member relative to the body along the first axis, means for driving the locking member by means of the maneuvering hood.
    [0007] The drive means allow on the one hand free movement of the locking member along the first axis relative to the maneuvering cover and relative to the body, and on the other hand allow the displacement of the locking member out the jamming position by operating the maneuvering hood.
    [0008] The maneuvering cap may comprise stop elements limiting the displacement of the body relative to the maneuvering cap and allowing a free play of movement between the body and the maneuvering cap. The drive means may allow free movement of the locking member along the first axis relative to the maneuvering cap and relative to the body when the maneuvering cap is in abutment against the body. According to one aspect of the invention, the drive means are configured to move in a hole in a wall of the body. The hole may be through and the drive means may be configured to move in the game in a wall of the maneuvering hood. According to an alternative embodiment, elastic means may be positioned between the wall of the body and at least one of the locking members, the elastic means being configured to move at least one of the locking members to the position of jamming. According to one embodiment of the device, the maneuvering cover comprises a cavity configured to house the body and allow the passage of at least one of the wire elements. According to one aspect of the invention, at least one of the locking members comprises at least one prism configured to lock at least one of the wire elements against a wall of the body.
    [0009] According to another aspect of the invention, at least one of the locking members comprises a wheel rotatable along a second axis orthogonal to the first axis, the wheel being configured to block at least one of the wire elements against a wall The invention may relate to a protective helmet comprising a locking device having the aforementioned characteristics, the locking device being able to be used to tighten or loosen neck straps of the protective helmet.
    [0010] The invention can also be used on lace-up shoes comprising a locking device having the aforementioned characteristics, the locking device being able to be used to tighten or loosen laces.
    [0011] The invention may also relate to a backpack having a locking device with the aforementioned characteristics, the locking device may be intended to tighten or loosen a closure cord of the backpack.
    [0012] Finally, the invention relates to a method of clamping the at least wire elements by means of a locking device provided with the aforementioned characteristics, the method comprising the following steps: - applying a voltage on at least one of the wire elements relative to the operating cover so as to move at least one of the locking members to an unlocking position, - stop said tension on at least one of the wire elements. The method for loosening at least one wire element comprises the following step: translating the maneuvering cover relative to the body until it engages the displacement of at least one of the blocking to a position of unlocking at least one of the wire elements.
    [0013] BRIEF DESCRIPTION OF THE DRAWINGS Other advantages and features will emerge more clearly from the following description of particular embodiments of the invention given by way of nonlimiting example and represented in the accompanying drawings, in which: FIG. schematically a perspective view of an embodiment of a blocking device; Figures 2 and 3 are sectional views showing two possible positions of the locking device according to a first embodiment, Figures 4 and 5 are truncated perspective views illustrating the two possible positions shown in Figures 2 and 3 of the device 6a and 6b illustrate the use of the device on a protective helmet.
    [0014] DETAILED DESCRIPTION The invention relates to a device 1 for blocking at least one wire element 2. According to the embodiment illustrated in the figures, the blocking device 1 is configured to allow the locking and unblocking of straps, in particular climbing helmet neckband straps. To block the wire element or elements 2, the locking device 1 is provided with at least one locking member 7 housed in a cavity 4d of a body 4. The cavity 4d of the body is also configured to allow the passage of the at least one of the wire elements 2. More specifically, the body 4 has at least one inlet hole 4a and at least one outlet hole 4b allowing the passage of the wire element (s) 2 in at least one displacement channel (no represent). The displacement channel passes through the body 4. For example, in the embodiment shown in FIGS. 2 and 3, the body 4 has two inlets 4a each traversed by a strap, an outlet 4b, and a cavity 4d of substantially frustoconical shape of which the base is located on the side of the entrances 4a.
    [0015] Inside the cavity 4d, at least one of the locking members 7 is movable along a first axis AA (see FIG. 1), and advantageously to a wedging position of the wire element or elements 2 against the 4. As a result, a translation of the locking member 7 in a first direction along the axis AA makes it possible to jam at least one of the wire elements 2, while they are released by a translation of the locking member 7 in a second direction opposite to the first direction. The locking member 7, the cover 4 and the operating cover 3 are integral.
    [0016] To manipulate the locking device 1, it advantageously comprises a maneuvering cover 3. The maneuvering cover 3 is movable in translation relative to the body 4 along the axis AA, and is configured to allow the displacement of the member 7 of blocking relative to the body 4. The locking member 7 can move relative to the maneuvering cap 3 and relative to the body 4 at the same time. Thus, the movement of the maneuvering cap does not necessarily cause the blocking member 7 to move. The locking device 1 advantageously comprises means 5 for driving the blocking member 7 by means of the maneuvering cover 3. The drive means 5 are configured to allow free movement of the locking member relative to the body 4 without coupling between the operating cover 3 and the locking member 7. In this first configuration, the blocking member 7 is free to move along the axis AA relative to the actuating cover 3 and relative to the body 4 when the operating cover 3 is in abutment against the body 4. The displacement of the locking member 7 can be achieved for example by actuating the wire elements 2. The drive means 5 are also configured to move the locking member 7 out of the jamming position by actuating the operating cover 3. In these conditions, if the locking member 7 is in its jamming position, simply move the operating cover 3 to leave the jamming position and reduce the stress applied to the wire element 2.
    [0017] In other words, the maneuvering cover 3 comprises stop elements limiting the displacement of the body 4 relative to the cover, these stop elements allowing a play of movement between the body 4 and the maneuvering cover 3. The means of 5 can move freely along the axis AA between these stop elements, so as to allow displacement along the axis AA of at least one of the locking members 7 relative to the maneuvering cover 3. The set of displacement is configured to allow the movement of the operating cover 3 to one of the stop members, so as to cause the translation of at least one of the locking members 7 out of the jamming position. The drive means 5 may be formed by any suitable means which allows to allow relative movement of the different parts relative to each other. Advantageously, the drive means 5 comprise at least one connector which is fixed on one of the three integral elements (ie the maneuvering cover 3, the body 4 and the locking member 7) and which moves to inside a cavity arranged in the other two elements.
    [0018] By way of example, as illustrated, it is possible to have a connector fixed to a locking member 7 and which moves in cavities 3b and 4d respectively provided in the maneuvering cover 3 and in the body 4. Alternatively, it is possible to have a connector attached to the operating cover 3 and which moves in cavities in the body 4 and in the locking member 7. Alternatively, it is still possible to have a first connector attached to the maneuvering cover 3 and which moves in a cavity arranged in the body 4. The body 4 has a second connector which moves in a cavity arranged in the locking member 7. There is also a connector which connects in certain conditions the operating cover 3 and the locking member 7.
    [0019] An opposite configuration can be achieved with a first connector fixed to the body 4 and cooperating before the operating cover 3, a second connector fixed to the locking member 7 and cooperating before the body 4 and a last connector which is fixed to the cover of maneuver 3 or blocking member 7.
    [0020] These various embodiments can be combined, for example to form connectors attached to the operating cover 3 and the locking member 7. These connectors move in separate cavities formed in the body 4 or in the same cavity. If the two cavities are distinct, an additional connector linking the movement of the actuating cover 3 with respect to the locking member 7 is used. As will be seen below, the game can be defined by means of an oblong hole 3c positioned on the walls of the maneuvering cover 3 (see FIGS. 4 and 5). The game can also be defined by means of a hole in the locking member 7. It is still possible to provide that the game is defined by a difference in position between two connectors. In the embodiment illustrated in Figures 4 and 5, the connector is formed by a rod 5 which moves in the oblong hole 3c. The rod 5 also moves in the hole 4c arranged in the body 4. It is observed that in a first configuration the rod 5 moves in the hole 4c without abutting the oblong hole 3c. It is therefore possible to have a displacement of the locking member 7 inside the body 4 and relative to the maneuvering cover 3. When the operating cover 3 is actuated, the oblong hole 3c moves up to contact the rod 5. Continuing movement of the operating cover 3, the locking member 7 is moved out of the jamming position. These drive means 5 are configured so that the driving of the locking member 7 with the actuating cover 3 occurs when the actuating cover 3 moves beyond a threshold position relative to the body 4 preferably in a release direction. In this way, when the maneuvering cover 3 is in a particular zone, the locking member 7 can move independently of the maneuvering cover 3. The locking member 7 is for example in a jamming position of the element or elements. 2, unless the wire element or elements 2 tend to move it out of the wedge position. When the threshold position is reached, there is a mechanical connection between the locking member 7 and the maneuvering cap 3 so that the maneuvering cap 3 can cause the blocking member 7 to move relative to the body 4 out of the wedging position of the wired element 2.
    [0021] If the locking member 7 is out of the jamming position, the mechanical coupling between the locking member 7 and the maneuvering cover 3 is obtained beyond the threshold position.
    [0022] Thus, under certain conditions, there can be a mechanical connection between the operating cover 3 and the locking member 7 so that the movement of the operating cover 3 causes the blocking member 7 to move. other conditions, the locking member 7 can move freely relative to the operating cover 3, there is no direct mechanical connection between these two elements. In this configuration, a movement of the maneuvering cover 3 with respect to the body 4 makes it possible to simply release the stress on the wire element 2. The use of drive means 5 comprising a movement clearance or allowing a free movement of the blocking member 7 relative to the operating cover 3 is particularly advantageous when the locking device 1 is configured so that the user grasps the locking device 1 by the operating cover 3. In fact, in the devices of the prior art, the operating cover 3 is used exclusively to make the loosening and the body 4 is used exclusively for clamping the wire element 2. The actuating cover 3 during the operating phase tightening makes it very difficult to move the wire element 2.
    [0023] To force the locking member (s) 7 to be placed in the jamming position, it may be envisaged to add elastic means (8) between the wall of the body (4) and the locking member (s). The elastic means (8) are then in position. rest position when the locking member (s) 7 are in the jamming position, and they are constrained when the locking member (s) 7 are out of the jamming position. The elastic means 8 may be formed by any suitable device, for example a spring, a blade acting in bending, a tube deforming to regain its original shape. When the wire element or elements 2 are straps, it may be advantageous to add elastic means 8 in the locking device. Indeed, the straps have the property of not deforming when they apply a traction force and can contribute to the displacement of the locking member 7 out of the wedge position.
    [0024] Conversely, when the locking device 1 is used to tighten laces, the elastic means are not necessarily useful. Indeed, laces generally have a thinner section when stretched than when they are at rest. Consequently, increasing the section of the laces when they are not stretched further is sufficient to initiate the jamming by the locking member 7. In general, the elastic means 8 are not necessary if the actuation of the wire element 2 towards the jamming position is sufficient to cause a displacement of the locking member 7 to the jamming position. Figures 1 to 5 show a detailed view of an embodiment of a locking device that can be mounted on a neck brace of protective helmet.
    [0025] To be fixed on a neckband, the locking device comprises fixing means 6. In this configuration, the body 4 is attached to the neckband, which facilitates the application of forces on the various elements of the blocking device 7.30 The fixing means 6 may comprise a rod which passes through one or more holes formed in the body 4. The rod or another element may be arranged at the outlet 4b of the body 4 in order to facilitate the positioning of the wire element in the body 4. Here, each strap passes on both sides of the rod. The fastening means 6 make it possible to limit the displacement of the locking device 1 with respect to the object on which it is fixed, here a helmet. Fixing the locking device 1 on the object to be adjusted is performed by means of the body 4. In this configuration, the force is applied to the wire element 2 by resting on the helmet. In a particular embodiment, the fixing means can be used to prevent the disengagement of the maneuvering cover 3 relative to the body 4. The rod 6 can be configured to form an end stop. Alternatively, the limit stop may be formed by the element to be adjusted. In the embodiment illustrated in the figures, the maneuvering cover 3 is advantageously provided with a cavity 3b whose shape is adapted to house the body 4 and allow the passage of at least one of the wire elements 2 at a time through the body 4 and through the maneuvering cover 3. The maneuvering cover 3 is more particularly structured to allow the passage of two straps, one on each side of the body 4. To facilitate the gripping of the maneuvering cover 3 by the user, it can advantageously be provided with a protruding portion 3a. A coil spring 8 allows the application of a restoring force from the body 4 on the locking member 7 in order to place it in the wedging position of the wire element 2. In the illustrated embodiment, the spring helical is disposed between the upper wall of the body 4 and the locking member 7, and more precisely inside a guide rail 4e arranged in the body 4. The locking member 7 may for example be a prism triangular base or trapezoidal (not shown), the large base is positioned on the side of the inputs 4a of the wire elements. The blocking of the wire element or elements 2 is produced by friction between the walls of the cavity 4d and the lateral sides of the prism.
    [0026] According to an alternative embodiment illustrated in the figures, the locking member 7 may be a freewheel rotated along the longitudinal axis of the rod 5. Using a wheel as a locking member 7 can block several wire elements 2 simultaneously , even if the tensile force is different on each wire element 2. The wheel may optionally be provided with teeth to increase the friction forces used for jamming the wire element or elements 2. The locking member 7 may also include several blocking elements, for example several wheels or several prisms it is also possible to combine these two embodiments. Here, the locking member 7 has a through hole (not shown) of axis BB orthogonal to the axis AA through which a rod 5 is inserted. The rod 5 cooperates with the holes 4c formed in the body 4, the holes 3c arranged in the actuating cover 3, to allow the displacement of the locking member 7 relative to these two parts. The holes 3c and 4c serve as a guide rail for the rod 5. The holes 4c are advantageously through, while the holes 3c can be through or not. It is particularly advantageous to use a rod 5 passing through the holes. through cavities in the body 4 and in the operating cover 3 because the manufacture and repair of the locking device 7 are facilitated.
    [0027] In this configuration, the movement of the maneuvering cover 3 relative to the body 4 can be effected without moving the locking member 7 to a certain extent. When the maneuvering cap 3 is moved relative to the body beyond a threshold position, the rod 5 abuts against the hole 3c, so that the maneuvering cap 3 comes into mechanical contact with the valve member. 7. From this moment, the locking member is driven by the operating cover 3, which results in a displacement of the locking member 7. However, if the locking member 7 is already in the unlocking position, there is not necessarily contact with the maneuvering cover 3.
    [0028] The holes 3c and 4c are advantageously formed in the operating cover 3 and in the body 4 so that the displacement path of the locking member 7 is formed by the edges of the holes. In a preferred embodiment, the hole 4c defines the two stops that define the extreme relative positions between the body 4 and the locking member 7, and the hole 3c defines the two stops that define the extreme relative positions between the body. blocking 7 and the operating cap 3.
    [0029] Advantageously, to limit the lateral displacement of the locking member 7 in the cavity 4d of the body, the rod 5 advantageously translates into the guide rail 4e of the body 4. This guide rail 4e is preferentially disposed in the center of the body 4 so as to limit the deformation of the locking member if significant forces are applied for example during tightening. The lateral displacement is limited along an axis perpendicular to the axis AA and the axis BB. Preferably, the guide rail 4e forms a housing zone of the elastic means 8. It is noted that it is particularly advantageous to size the cavities 3b of the maneuvering cover and 4d of the body 4 to ensure the joining of the parts together and / or to achieve the drive of the locking member 7 with the actuating cover 3. In this way, the device is particularly compact and robust because the number of parts used is reduced.
    [0030] Alternatively, the drive means of the locking member 7 with the operating cap 3 may be formed by other elements and in particular by a projecting piece for example a rod 5 which moves inside the body 4. This embodiment is particularly interesting if the cavities 4c are not through.
    [0031] For example, a rod integral with the operating cap 3 and projecting inside the cavity 4a of the body 4 may be used. When moving the operating cover 3, the rod moves until it comes into contact with the locking member 7 and cause it to move. These means may for example be configured to fit through the outlet hole 4b in the cavity 4d of the body 4, and push the rod 5 in the unlocking direction when the user moves the operating cover 3 in the same direction.
    [0032] This embodiment is less interesting than the previous one because it requires the use of a rod which passes through the body 4 and the maneuvering cover 3 to actuate the locking member 7. To use the locking device 1 in order to block one or more wire elements 2, the user must first apply a voltage on the wire element or elements 2 relative to the body 4, so as to move the wire element or elements 2 relative to the blocking device 1 to an unlock position. The force applied on the wire element or elements 2 makes it possible to move the locking member 7 along the direction A1 (FIG. 2). The locking member 7 moves towards the unlocking position and it can be in abutment against the body 4 and / or the maneuvering cover 3. Advantageously, the locking member 7 is in abutment against the body 4 so as to take advantage of a maximum amplitude for the passage of the wire element or elements 2. The force applied on the wire element or elements 2 comes to counter the force applied by the elastic means 8 and the wire element or elements 2 can move between the blocking member 7 and the wall of the body 4. In an advantageous embodiment, the tensioning force is applied to the wire element or elements 2 relative to the maneuvering cap 3 which presses against the body 4 This embodiment is particularly advantageous when the wire element or elements 2 make it difficult to access the body 4, for example when at least two straps are used and pass on either side of the locking member 7.
    [0033] As soon as the force disappears or decreases below a threshold value, the locking member 7 is placed in the blocking or jamming position. The wire element or elements 2 are then wedged between the wall of the body 4 and the locking member 7.
    [0034] Pulling the wire element (s) 2 relative to the body 4 and preferably relative to the operating cap 3, allows the rod 5 to translate in the direction AA, and the locking member 7 to move out 2.30 When the user the tension force decreases, for example when the user releases the maneuvering cover 3 and / or the wire elements 2. The friction forces between the walls of the cavity 4d and the locking member 7 cause the blocking or the wire elements 2. These are blocked in the desired position by the user. To achieve the unlocking of the wire element or elements 2, actuation of the maneuvering cover 3 makes it possible to move the locking member 7 which moves from the jamming position towards the unlocking position.
    [0035] Actuation of the maneuvering cover 3 results in movement of the operating cover 3 with respect to the body 4. In a first part, the cover 3 is moved without causing the locking member 7 to be actuated. cover 3 mates with the locking member 7 which leaves the jamming position.
    [0036] In this case, if no force is applied to the wire element or elements 2, the latter move to reduce the clamping force that it supports. It is also possible to apply a force on the wire element (s) 2 in the opposite direction to the clamping.
    [0037] By releasing the operating cover 3, the locking device 7 stops in the position chosen by the user. The locking device 1 can be used wisely on sports articles, for example on a protective helmet to adjust the neck strap straps as shown in the figures. In this configuration, when the helmet is placed on the head of the user, simply pull on the wire elements 2 to obtain the tightening of the helmet. In the same way, the actuation of the maneuvering cover 3 makes it possible to loosen the helmet easily. The helmet can be adapted to the size of the head of the user, and ensure optimal use of the helmet.
    [0038] The locking device 1 can also be used on lace-up shoes in order to tighten and lock them. The device prevents any unwanted loosening of the lace, which can generate discomfort to the user.
    [0039] The backpacks may also be provided with a locking device 1, for example to tighten the cord of a sealing skirt to protect the contents of the bag.
    [0040] Without departing from the scope of the invention, those skilled in the art can very well combine the various technical characteristics which have just been described. The locking device may for example not be placed on any fixed element, as in the case of use to tighten laces of shoes.
