    [0001] FIELD OF THE INVENTION The invention relates to a device for winding and locking a tightening lace. It finds a particular application in the field of lacing personal equipment such as clothing, shoes, helmets, protective equipment by allowing a lacing, more generally a clamping, fast and accurate. STATE OF THE ART There are several types of devices for winding and locking a lace. In general such devices comprise a fixed support connected to the equipment, a coil for winding or unwinding of the lace at its periphery and means for locking the coil in a winding position. An element, frequently a wheel, is provided so that the user of the equipment can control the locking in position of the coil. For example, US-A-8 468 657 discloses a device for winding and locking a lace having a coil and means for locking its rotation. In this document, the locking means consist of three thin engagement rods integral with one end of the coil and the other end of which comprises a blocking surface capable of being embedded in a toothing for block the rotation of the coil. Each engagement rod forms a ratchet. This document also shows a release surface carried by each of the engagement rods and may be brought into contact with a drive pad of the wheel in order to bend the engagement rods. The presence of the three engagement rods makes it possible to balance the coil and to distribute the retention forces of the rotation at three points. On the other hand, it presents the disadvantage of posing problems of complexity of construction and hyperstatism. In addition, this system is in practice relatively fragile and not adapted to withstand high tension of the lace. The fragility is further accentuated by the fact that the locking and unlocking surfaces are placed close to each other. Patent IT-A-1,220,811 also discloses a winding and locking device of a lace which partially solves the problem of fragility. In this document, there is provided a single massive ratchet which comes into contact with a peripheral toothing. The means which make it possible to subtract the pawl from its engagement with the toothing consist of a cam surface formed on the pawl, which is placed close to the axis. It is also provided a spring pushing the pawl in position. Such positioning is unfavorable in terms of moment and the user must exert a relatively large torque to proceed with loosening, which makes this loosening difficult. On the other hand, the presence of a spring in this device makes the construction of the device more complex and heavier. However, for some applications, especially for clothes or shoes or similar objects, the lightness is a very important parameter. The problem underlying the present invention is to design a device for winding and locking a tightening lace that is simple in design while having improved strength. SUMMARY OF THE INVENTION For this purpose, provision is made according to the invention for a device for winding and locking a tightening lace for personal equipment of the clothing, shoe, helmet or protective equipment type, the device comprising a fixed support, a spool that is rotatable relative to the fixed support and is intended to be tied to the lace for its tightening or loosening, a wheel for driving the spool that can be actuated by a user, and elements for locking the rotation of the spool, characterized in the locking elements comprise at least one pawl having: a retention portion configured to engage, in a rotational locking position, at least one complementary relief integral with the fixed support in the absence of a rotational force exerted by the user on the wheel; a base configured to be rotated when the wheel is rotated by the user in the direction of loosening; a first bar carrying the retention portion, the first bar being elastically deformable to cause, when deformed, the disengagement of the retention portion of said at least one complementary relief. Preferably, the bar separating the retention portion of the base; an actuating portion of the retention portion, this actuating portion being carried by a second bar being remote from the retention portion; the pawl being configured so that, in a direction of rotation of the wheel corresponding to loosening, the wheel, via the actuating portion, causes the disengagement of the retention portion of said at least one relief complementary. This makes it possible to obtain an easy release while reinforcing the mechanical strength of the locking means. The contact surface of the retention portion is at least as large as that provided by the device according to the state of the art closest. The pawl of the device according to the present invention is urged respectively in tightening and loosening by the wheel in two different places spaced from each other: on the base carried by the first bar, on the one hand, and on the portion actuation carried by the second bar, on the other hand. There is therefore distribution of the forces on a large surface of the pawl which reduces the risk of wear and rupture of the pawl. In addition, the fact of moving the actuating portion away from the retention portion increases the strength of the pawl, contrary to the state of the art of US-A-8 468 657 where the locking and unlocking surfaces are placed close to each other. Indeed, in the context of the development of the present invention, it has been noted that the fragility of the device described in US-A8 468 657 comes at least in part because the locking and unlocking surfaces are placed in the vicinity one from the other. Therefore, the sizing of each engagement rod must be such that the wheel turning can easily bend. Such a dimensioning makes it fragile and not very resistant to retaining a high tension of the lace. It follows that such a device can not be subjected to a too strong lace tension. Finally, the positioning of the actuating portion on the second bar, preferably at the free end of the second bar, provides a large lever arm which helps to disengage the retention portion of the complementary relief and thus allows an easy unlock. Optionally, the invention has any of the preceding features that may be used separately or in combination. According to one embodiment, the actuating portion is disposed in the vicinity of a first end of the second bar, the second bar comprising a second end by which the second bar is integral with the first bar. This allows to have a maximum lever arm for disengagement of the retention portion of the complementary relief and thus the release of the coil. According to one embodiment, the actuating portion is driven by a first integral drive member of the wheel. This allows a drive limited to the actuating portion and therefore more effective. According to one embodiment, the first drive member is in the form of a drive stop pushing the actuating portion carried by the second bar for unlocking the rotation of the wheel, this thrust deforming the first bar in order to disengage the retention portion of the complementary relief of the fixed support. The deformation of the first bar helps the thrust of the drive abutment by not opposing this thrust and decreases the friction and therefore the wear of the stop and the body. According to one embodiment, in the tightening direction, the driving abutment is configured to push an actuating element integral with the spool in order to rotate the spool in this direction. This driving abutment has the advantage of combining two functions, on the one hand, a thrust function on the drive member in the loosening direction and, on the other hand, a thrust function on an element. of the coil in the direction of tightening. This is therefore achieved with the same element hence a decrease in the elements necessary for the operation of the winding device and also a decrease in the total weight of the device, which is important when the personal equipment must be light. According to an embodiment that can be combined with the previous mode or implemented individually, the retention portion is in the vicinity of a first end of the first bar, the base being in the vicinity of the second end of the first bar. There is therefore distribution of efforts on the entire pawl so that the pawl is solicited all around its periphery, which weakens it less. According to one embodiment, in the direction of loosening, the base is pushed by a second drive member secured to the wheel. This characteristic relates to the second drive that the wheel exerts on the pawl at a different location from the first, which still allows a distribution of forces on the entire ratchet. According to one embodiment, the pawl is secured to the coil near the base, a fork carried by the pawl surrounding a fastening element carried by or secured to the coil, the base forming one of the branches of the fork. Thus, the place where the pawl is pushed by the second member is also the place of its attachment to the coil which improves the transmission of the forces of the wheel to the pawl and then to the coil. According to one embodiment, the device comprises a noise element configured to rub against the inner periphery of the fixed support under the action of a rotational force exerted by a user on the wheel in the loosening direction. The sounding element serves to guide the user to the sound during loosening, the retention portion not then rubbing against the inner periphery of the fixed support. This represents a significant advantage over a solution of the type described in US-A-8 468 658. In this solution of the prior art, since there is no contact between the rod of engagement and teeth when turning the wheel in the direction of loosening, the user has no audible indication of the length of lace that is unwound, the engagement rod producing no friction noise on the teeth . According to one embodiment, the noisemaker element is carried by an arm which extends from the first bar so that the deformation of the arm causes the friction of the noisy element against the inner periphery of the fixed support under the action of said rotational force exerted by a user on the wheel in the loosening direction. Preferably, the arm comprises a first end through which it is secured to the first bar and a second end which forms lo the noise element. According to one embodiment, the device comprises a second drive member integral with the wheel and configured to push the base under the action of said rotational force exerted by a user on the wheel in the tightening direction, and wherein the second drive member also forms said abutment 15 away. According to one embodiment, the arm is elastically deformable, a distance stop carried by or secured to the wheel now spaced from the inner periphery of the support fixed the free end of the arm, this during tightening. This makes it easier to place the arm against the periphery of the fixed support so that it fulfills its role as a buzzer during loosening and away from the contact with the periphery so as to make no noise at the end of clamping. According to a preferred form of this embodiment, when the base is pushed by a second drive member secured to the wheel, the second drive member also forms the distance stop. The second organ performs as the first organ two functions: there is thus simplification of the device and economy of the elements to be implemented for its operation. According to one embodiment, the complementary relief integral with the fixed support is formed of notches into which a respective tooth carried by the retention portion is inserted. The device is configured so that in the absence of said rotational force exerted by a user on the wheel in the loosening direction, at least one tooth carried by the retention portion fits into a notch. For example, the number of teeth carried by the retention portion may be between 1 and 5. The contact between complementary relief and retention portion is thus reinforced compared to that obtained according to the state of the art closest to the 35 engagement rod and the fixed support which is unique. According to one embodiment, the first bar has at least for its retention portion an external curvature oriented towards the fixed support corresponding to that of the inner periphery of the fixed support. The first bar therefore has a configuration specifically adapted to the inner periphery of the fixed support, which increases the engagement between the retention portion and the complementary relief in the locking position of the coil. According to one embodiment, the device comprises a single pawl, the single pawl can carry a single retention portion. Compared to the closest state of the art which comprises three engagement rods, this represents a simplification of the device with a saving in manufacturing time and elements that the device contains. According to one embodiment, the pawl is formed integrally. In particular, the base, the first and second bars, the actuating portion and the retention portion form a single piece. They are trained come matter. According to another object of the invention, there is provided personal equipment of the clothing, footwear, helmet or protective equipment type having at least one tightening lace, comprising for said at least one lace such a winding and locking device according to the invention. The tightening thus obtained is fast and resistant in position. In the context of the invention, there is finally provided a device for winding and locking a tightening lace for personal equipment of the clothing, footwear, helmet or protective equipment type comprising a fixed support, a rotating coil by relative to the fixed support, a wheel for driving the reel and elements for blocking the rotation of the reel, characterized in that the elements for blocking the rotation of the reel comprise a pawl, said pawl comprising a base, a portion retainer disposed away from the base on a first elastically deformable bar and an actuating portion of the retention portion carried by a second bar being away from the retention portion.

DETAILED DESCRIPTION OF THE INVENTION Referring to all the figures, the present invention relates to a winding and clamping device 100 of a clamping lace 400 for personal equipment such as clothing, shoes, helmet, protective equipment. The device 100 comprises a fixed support 200, a spool 300 rotatable relative to the fixed support 200 and intended to be connected to the lace 400. The lace 400 is wound around the spool 300. A first end (not shown) of yaw is fixed to the fixed support, the other end 401 is fixed to the coil. The first strand of the lace, linked to the first end, is visible on the left in FIG. 1. The second strand which enters on the right in FIG. 1 wraps around the spool 300 so that the two strands are simultaneously tightened, respectively loosened, during the same rotation of the wheel. As illustrated in FIG. 4, the fixed support 200 rests on the personal equipment being fixed thereto by a base 221. The fixed support 200 also comprises, among other elements, a cylindrical portion 220 carried by the base 221. Referring to all the figures, the fixed support 200 may thus comprise several elements integral with each other removably or not, including a central axis 230 for a wheel, which will be described later. For example, the fixed support 200 may comprise a housing portion 30 receiving inside the coil 300, this housing portion can be removable from the base 221. It is this housing portion which is referenced 200 in Figures 1 to 3 . Referring more particularly to Figures 1 to 3, the device 100 also comprises a wheel 500. This wheel 500 is used to drive the coil 300 in rotation. The wheel 500 substantially forms the contour of the device 100 by covering it at its upper face when the device 100 is fixed on the personal equipment and having a substantially circular slice.
    [0002] The wheel 500 rotates about a central axis 230 fixedly or non-detachably fixed support 200. For this the wheel 500 has an inner cylindrical housing 530 to the device 100 and receiving the central axis 230. The user can operate the wheel 500 by its edge or by an element carried by its upper face and projecting from this face, the latter embodiment being not shown in the figures. Finally, the device 100 comprises locking elements 210, 600 of the rotation of the coil 300. The locking elements 210, 600 of the rotation of the coil 300 comprise at least one pawl 600. The or each pawl 600 carries a 10 retention portion 611 engaging with at least one complementary relief 210 carried by the fixed support 200. In the preferred embodiment illustrated in the figures, the pawl 600 is unique and has a single retention portion 611. Still according to the mode embodiment shown in the figures, the aforementioned housing portion of the fixed support 200 is in the form of a ring and houses inside the pawl 600 and the coil 300. For simplification, this housing portion being part of the support will be called fixed support 200. The inner periphery of the device 100 of the fixed support 200 carries at least one notch 211, preferably several notches 211. The notches 211 are distributed over the entire inner periphery of the fixed support 200. Each notch 211, when facing the retention portion 611 of the pawl, forms the complementary relief 210. The retention portion 611 carries at least one tooth 612 which can penetrate into said at least one notch 211 of the complementary relief 210. By way of example, without being limiting, this number of teeth 612 can vary from 1 to 5. In FIGS. 1 to 3, four teeth 612 are shown for the portion 611. The notches 211 are inclined by having a substantially radial side to the device 100, this side being oriented in the loosening direction of the coil 300. The other side is inclined so that the entrance of the notches 211 is more great than their bottom. The retention portion 611 is thus configured, in a locking configuration, to engage at least the complementary relief 210 integral with the fixed support 200 in order to block the rotation of the coil 300 in the absence of an effort of Rotation exerted by a user on the wheel 500. This retention portion 611 is also configured to allow the rotation of the coil 300 relative to the fixed support 200 under the action of a rotational force exerted by a user on the wheel 500 in a tightening direction and in a loosening direction, this by elastic deformation as will be described later.
    [0003] In the example illustrated in Figures 1 to 3, the clamping direction corresponds to a rotation of the wheel 300 in the opposite direction of that of the clockwise. This direction is illustrated by the arrows Es of Figure 1. The direction of loosening corresponds to a rotation of the wheel in the direction of that of the clockwise. This direction is illustrated by the arrow Fd of FIG. 3. The blocking position also referred to as the blocking configuration corresponds to the case where the user does not drive the wheel 500 in rotation. In this case, the lace 400 remains blocked when traction is applied thereto. Hereinafter the composition of the pawl 600 will be described.
    [0004] The pawl comprises a first bar 610 which carries the retention portion 611. This first bar 610 is elastically deformable in order to disengage the retention portion 611 of the complementary relief 210 integral with the fixed support 200 when an action of the user is transmitted to it by the wheel 500. Per bar, it is understood an elongate member having two ends, this shape is not necessarily straight. In the embodiment shown in the figures, the first bar 610 has, on its face facing the fixed support 200, a curved shape corresponding to the curvature of the inner periphery of the fixed support 200, that at least for the retention portion 611 it carries.
    [0005] The fact that the bar designates a generally elongate shaped member also applies to a second bar 620 which will be described later. Deformation of the first bar 610 causes disengagement of the retention portion 611 with respect to said at least one complementary relief 211 carried by the fixed support 200.
    [0006] To deform the first bar 610, when the wheel 500 is driven in the loosening direction, and consequently disengage the retention portion 611, there is provided on the pawl 600 an actuating portion 622. In the embodiment illustrated in FIGS. FIGS., the actuating portion 622 is disposed away from the retention portion 611. This actuating portion 622 is carried by a second bar 620. In this embodiment, the second bar 620 is attached by one of its members. the first and second bars 610, 620 are not in line with one another but form an angle of approximately 90 ° between them.
    [0007] The second bar 620 may carry the actuating portion 622 near its free end opposite that attached to the first bar 610, this free end may for example form the actuating portion 622.
    [0008] The pawl 600 is configured so that, in a direction of rotation of the wheel 500 corresponding to the loosening, the wheel 500 moves the actuating portion 622, said displacement of the actuating portion 622 causing the disengagement of the portion 611 of the complementary relief 210 of the fixed support 200. The actuating portion 622 is moved under the action of a first drive member 510 integral with the wheel 500. This first drive member 510 is configured to be driven in rotation directly or indirectly by the wheel 500. to In the embodiment of the figures, this actuating member is in the form of a first drive stop 510. The drive stop 510 pushes the portion of actuating 622 and consequently the second bar 620, which deforms the first bar 610 and disengages the retention portion 611 of the complementary relief 210 of the fixed support 200. It is provided a cavity 615 in the first bar 610 near the retention portion 611 which allows it to be flexible. As previously mentioned, the second bar 620 can be connected to a first end of the first bar 610, the retention portion 611 being carried by the first bar 610 in the vicinity of this first end. In the vicinity of the opposite end of the first second end bar 610, so the end of the bar 610 does not bear the retention portion 611, the first bar 610 of the pawl 600 carries a base 614 configured to be rotated directly or indirectly by the wheel 500 in a direction of rotation of the wheel 500 corresponding to the loosening. In the loosening direction, the base 614 is pushed by a second drive member 520 integral with the wheel 500. In the embodiment shown in the figures, the pawl 600, via its first bar 610, is integral with rotation of the coil 300, this close to the base 614. This is achieved by a fork 613 carried by the first bar 610 of the pawl 600 surrounding a securing element 320 carried by or integral with the coil 300. As illustrated on the figures, the base 614 forms one of the branches of the fork 613, this branch may be the outermost to the first bar 610. The fork 613 being in the vicinity of the base 614 sandwiches between two branches the fastener 320. L securing element 320 transfers the rotation of the wheel 500 to the coil 300. In branch of the base 614, in the vicinity of its second end, the first bar 610 is also extended by an arm 63 0 noiser forming, the free end 631 of the arm 630 rubbing against the inner periphery of the fixed support 200 under the action of a rotational force exerted by a user on the wheel 500. The free end 631 can then be set contact with the inner periphery of the fixed support 200 carrying the notches 211 and emits a noise when the free end 631 slides against the inner periphery of the fixed support 200 carrying at least one notch 211, this for example during the action of a rotation force exerted by a user on the wheel 500 and more particularly to loosening. The user can easily control the loosening done. The arm 630 can be brought into contact with the inner periphery of the fixed support and then be moved away from this periphery. A cavity 616 may be provided in the first bar 610 between the base 614 and the attachment of the arm 630 with the first bar 610 to provide some elasticity to the arm 630 allowing it to easily take the contact positions respectively with the fixed support 200 and away from the fixed support 200.
    [0009] The illustrated embodiment shows a second possible function of the drive member 520 integral with the wheel 500 as a stop away from the free end 631 of the arm 630 the inner periphery of the fixed support 200, this second stop being said distance stop. This distance stop 520 approaches the noisemaker arm 630 by moving away from the base 614 during clamping and prevents the free end 631 of the buzzer 630 from coming into contact with the inner periphery of the fixed support 200 and thus of make a noise when the free end 631 slides along the inner periphery by keeping this end 631 away from the periphery. This makes it possible not to use the noisemaker arm while a ratchet noise can be obtained by the friction of the teeth 312 on the reliefs of the crown. Referring to Figures 1 to 3, the various phases of clamping, locking and loosening of the lace 400 by the winding and locking device 100 will now be described. This embodiment is not limiting. In FIG. 1, during tightening, the user of the equipment provided with at least one lace 30 with a winding and locking device 100 according to the invention turns the wheel 500 in the direction of the clamping arrow Fs. , only one of which is referenced in this figure. During this rotation of the wheel 500, the first and second drive members 510, 520 which are integral with the wheel 500 follow this rotation. The first drive member 510 comes into abutment with the actuating element 310 integral with the spool 300 and pushes the actuating element 310 in rotation in the direction of the clamping arrow Fs. The coil 300 is then driven in the tightening direction.
    [0010] The second drive member 520 does not then carry out a drive function but serves as a stop away from the free end 631 of the noisemaker arm 630 by moving this end 631 away from the inner periphery of the fixed support 200. it is indeed not necessary to use the sounder to evaluate the number of notches 211 of the inner periphery of the fixed support 200 already crossed during the rotation. Indeed, a noise is already emitted by the teeth 612 of the retention portion 611 having been in contact with notches 211 of the inner periphery of the fixed support 200, which allows the user to estimate the rotation achieved by the coil 300 and thus the clamping.
    [0011] During tightening, the noisering arm 630 and the second bar 620 are in contact at diametrically opposite points of the cylindrical housing 530 for receiving the wheel 500 surrounding the central axis 230 of rotation of the device 100. This allows a centering of the pawl 600 in the device 100. In Figure 2, the tightening is completed. The user no longer rotates the wheel 500. A locking is done in the position of the pawl 600 and consequently of the coil 300, because of the interaction of the retention portion 611 of the pawl 600 with the complementary relief 210 at the inner periphery of the fixed support 200, the teeth 612 of the retention portion 611 having penetrated into notches 211 of the complementary relief 210.
    [0012] As shown in Figure 2, the coil 300 is integral in rotation with the pawl 600 by the fastening element 320 inserted in the fork 613 near the base 614 carried by the first bar 610 of the pawl 600. However if such solidarization is permanent, it can also be considered a temporary joining of the coil 300 with the pawl 600.
    [0013] In the locking position, the second drive member 520 of the wheel 500 is always interposed between the free end 631 of the noisemaker arm 630 and the inner periphery of the fixed support 200. The first drive member 510 of the wheel 500 is always in abutment with the actuating element 310 integral with the coil 300 but no longer acts on this element 310. A traction exerted on one or other of the strands of the lace 400 is then transferred to the spool in the form of a rotational force, rotational force blocked by the pawl 600, on the one hand integral in rotation with the spool and on the other hand secured to the fixed support 200 through the cooperation of the pawl 600 with the reliefs of the fixed support 200. The lace 400 is thus blocked even under the action of a large traction. As shown in Figure 3, when loosening, the user turns the wheel 500 in the direction of the loosening arrow Fd. The first drive member 510 of the wheel 500 stops abutting with the actuating element 310 and rotates in the direction of the arrow Fd to come into contact with the actuating portion 622 at the free end. the second bar 620. The drive element 510 pushes the actuating portion 622 in the loosening direction, which causes the deformation of the first bar 610 and the disengagement of the retention portion 610 from the complementary relief: the blocking is then deleted. The second drive member 520 also follows the rotation of the wheel 500 and no longer performs its function as a distance stop of the free end 631 of the lo 630 forming noise generator. The free end 631 of the arm 630 then rubs against the inner periphery of the fixed support 200, which allows the arm 630 to perform its function of noise and provide the user with sound guidance for the evaluation of the loosening. The second drive member 520 having ceased to be interposed between the free end 631 and the inner periphery of the fixed support 200 comes into contact with the base 614 towards the end of the first bar 610. This second drive member 520 then performs a rotational drive function according to the loosening arrow Fd of the base 614 and consequently the pawl 600 and the coil 300, the latter being secured to the base 614 by its securing element 320 received in the fork 613 In view of the above description, it is clear that the invention provides a robust, simple and reliable solution to provide easy and precise clamping and loosening as well as high tensile strength in the operating position. blocking. The described embodiment corresponds to a cable winder whose tightening is done by rotation in the anti-clockwise direction. For example, this retractor will be placed on a left shoe. A symmetrical embodiment in which the clamping is done by clockwise rotation is also considered in the context of the invention.
