    Technical area
    The present invention relates to the field of shoes. More specifically, the invention relates to a shoe comprising an integrated automatic lace tightening means.
    State of the art
    Most shoes have laces that must be tightened and tied before walking, forcing wearers to bend and / or crouch to manipulate the laces. For various reasons, lacing can be problematic: balance problems, accidents, osteoarthritis, hand injuries ... For people in a hurry, lacing can be considered a waste of time. The automatic lacing of shoes is a solution to these different issues and solutions have already been developed.
    WO 2004/034831 for example describes an assisted lacing shoe. In a variant of the invention, two laces intersect above the tongue of the shoe to form a lacing on the front part of the shoe. Each lace has one end fixed at a lower eyelet (close to the toes), goes up passing crosswise through the eyelets along the tongue, then is guided in the wall of the shoe to the sole, where its opposite end is connected to a clamping mechanism. The clamping mechanism is housed in a cavity of the sole, under the heel. It includes an axis with ratchet wheel on which wind laces. A lace called "engagement lace" is wound in the opposite direction of the laces. The tightening of the laces is done by pulling by hand the engagement lace thus activating a mechanism. A lever associated with the ratchet wheel releases the axle and loosens the laces.
    The solution proposed in WO 2004/034831 allows faster lacing, but it is not completely automated. In addition, given the path of the laces on and in the shoe, and the point of application of the clamping force, it is clear that the bottom of the lacing will, in practice, poorly tightened. Finally, the proposed mechanism is complex.
    WO 2009/134858 discloses an integrated automatic lacing shoe, electrically actuated. The laces are flat, ribbon type, and each fixed by one end to the edge of the rod bordering the tongue. The laces cross the tongue, parallel to each other, to engage in the opposite side of the stem and join the sole. In the sole, the ends of the laces are attached to a drawbar. The drawbar is movable transversely (relative to the length of the shoe) by means of two rough coupling strips cooperating with two toothed rollers mounted on a shaft driven by an electric motor. Rotating the motor in one direction or the other makes it possible to tighten or loosen the laces.
    The proposed solution WO 2009/134858 is fully automatic, the user having only to put on and press a button to tighten the laces. But it can be noted that the tightening is done by pulling only on a lateral side of the rod, which can be unpleasant. Moreover, the mechanism described is large and complex.
    Object of the invention
    An object of the present invention is to provide a shoe with an improved automatic lacing device, of simple design and effective clamping.
    Another object of the invention is to provide a shoe with an improved automatic lacing device able to take into account the boot of the shoe wearer.
    General description of the invention
    The present invention relates to an automatic lacing shoe, comprising a sole assembly surmounted by a shaft and a set of laces for tightening the shaft by bringing two regions of the shaft together. An electrically actuated lashing means is arranged in a housing of the sole assembly, and adapted to be tripped selectively by the user to tighten or loosen the laces.
    According to the invention, a set of laces comprising one, preferably several, first (s) lace (s) as well as one, preferably several, second lace (s) is used. The first yaw (s) have a first end anchored to a first shank region, the first yarn (s) passing over the foot to a second shank region, to lace clamping means by which each first lace is driven by its second end. In addition, the second yaw (s) have a first end anchored to the second shank region, the second yarn (s) passing over the foot to join the first shank region to the first shank region. by means of tightening laces through which each second lace is driven by its second end.
    The shoe according to the invention thus comprises a set of laces which are anchored (that is to say fixedly attached to the rod) on opposite parts of the shank, and preferably a plurality of laces anchored in several places, for more effective foot clamping Advantageously, the laces are disposed substantially transversely to the axis of the cut separating the two rod regions, alternately, and substantially parallel to each other. Thus, we do not use long laces crossed and slippery patterns, but several laces that simply cross (in a straight line) the shank area to be clamped and are each individually connected to the clamping means.
    In practice, the set of laces comprises at least 2 or 3 first laces and at least 2 or 3 second laces, or more depending on the longitudinal dimension of the rod regions to be brought together.
    According to one embodiment, the clamping means comprises a winding drum coupled to an electric motor, preferably via an integrated gearbox. This retractor drum may comprise a rotary shaft with a respective winding section for each yaw winding end. The set of first and second laces wind on the same drum drum, each at their respective winding sections. For this purpose, the winding end of each lace is fixedly attached to the winding drum in the respective winding section. For example, the winding end of each lace may be engaged in a through-hole of the winding drum, or welded, glued, or tied around the winder drum. The drum drum is preferably positioned in the sole approximately at the height of the laces.
    Preferably, the laces are at least partly guided in sheaths along the rod, the sheaths being visible or integrated into the wall of the rod, for example between the rod itself and the inner lining.
    Note that the term "lace" is here understood in its traditional sense, that is to say a flexible cord, typically flat or round section, able to tighten the stem of a shoe.
    It will further be appreciated that, according to an advantageous variant of the invention, the first end of each lace is fixed to the rod by means of an anchor point comprising a manual means of fine adjustment of the tightening of the lace allowing a tension adjustment. of it independently of electrical clamping. This manual fine adjustment means can take any appropriate form, the idea being to allow a slight tightening or loosening of the lace. For example, a short portion of lace may be wound on an axis mounted in a housing provided in the rod. The anchor may for example take the form of a banjo screw, or the like. In particular, the screw is formed of a threaded rod with a head, and comprising at the base of the head a section, generally smooth, with a through hole, hole in which engages the first yaw end. The threaded rod cooperates with a threaded cylindrical sleeve fixed in the rod. The screw head is adapted to be handled manually by hand (for example a throttle or a thickened portion) or by means of a tool (eg screwdriver or specially adapted tool).
    The automatic lace tightening means comprises a control unit configured to operate the rotation of the motor in the direction of tightening or loosening.
    For actuation of the clamping device, a control knob is advantageously arranged on the boot so as to be accessible from the outside of the boot, and is connected to the control unit. One can for example place such a button at the sole.
    Alternatively or in addition, the control unit is configured to communicate wirelessly with a communicating terminal, from which a user can control the tightening or loosening of the laces. The communicating terminal is typically configured to adjust the two shoes of the same pair, and to memorize tightening settings of one or more shoes / pairs. The invention can be implemented in all types of shoe laces, whether sports shoes, city, walking, relaxing, etc.

    Detailed description of at least one embodiment
    The attached figures show an alternative embodiment of a shoe 10 comprising the present electrically actuated means for tightening laces, hereinafter also called clamping device.
    The shoe 10 mainly comprises a sole 12, lower part which protects the soles of the feet, more or less raised at the back by the heel, and a rod 14, the upper part which surrounds the foot. It can be limited to the ankle or rising.
    Conventionally, the sole 12 or sole may be declined in one or more parts. There is generally an upper sole layer in direct contact with the foot of the user and a lower sole layer in direct contact with the ground or more generally the external environment.
    The shoes whose upper covers the upper of the foot conventionally have a longitudinal opening (or cut or indentation) in the rod at the kick. This opening is covered by a tongue 30 and tightening laces are positioned on the opposite edges of this opening.
    With reference to FIGS. 1, 2 and 4, the stem 14 can be distinguished as follows: the anterior part 16 located at the level of the top of the toes (also often called a vamp); a rear part 18 which surrounds the heel; an outer lateral portion 20 (also called outer quarter), with an edge portion 22 delimiting a central opening 24 on the top of the foot; an inner lateral portion 26 (also called inner quarter), with an edge portion 28 delimiting the central opening 24; - A tongue 30 extending on the top of the foot from the front portion 16, covering the opening between the edges 22, 28 of the side portions.
    A set of laces is provided for clamping the rod at the opening 24, bringing the edges 22, 28 closer. These laces are part of the lacing system of the shoe and cooperate with the laces tightening device shown in FIG. in detail in Figure 5.
    It will be noted that part of the laces, called the first laces 32, have their first end 32i anchored to the edge 22 of the outer lateral portion 20 of the shank, these first laces passing over the foot to join the opposite shank portion, that is, the inner side portion 26, up to the lace clamping device by which they are driven by their second end 322. The other part of the laces constitutes the second laces 36, and have a first end 36i anchored on the edge 28 of the inner side portion 26 of the shank, these second laces 36 passing over the foot to join the outer side portion 20 to the lashing means by which they are driven by their second end 362.
    There are thus 6 individual laces 32, 36, each being attached to a rod edge, passing transversely (relative to the axis of the opening in the rod, here confused with the longitudinal direction of the shoe) on top of the foot, one time, before passing along the foot to reach the clamping device.
    FIG. 5 schematically illustrates the clamping device, designated 40, such that it can be integrated in the sole assembly 12. The device 40 comprises a winding drum 42 rotatably coupled to an electric motor 44, which preferably incorporates a gearbox (Not shown), and the laces have their second end 322 and 362, opposite to that anchored at the rod edges, engaged on the drum drum 42 and attached thereto.
    In the variant embodiment, the drum drum 42 is in the form of a rotating cylindrical shaft, the motor end 44 of which is directly coupled to the axis 46 of the motor, and the other end is supported by a bearing stud 48 which protrudes from the end wall 50 of a housing 52 accommodating the clamping device 40. The reference sign 54 designates a rechargeable battery.
    With particular regard to the drum drum 42, it comprises a plurality of winding sections (here thus six in number) distributed axially, the space of each winding section being delimited by a radially extending wall (not shown ). At each section the shaft is pierced with a hole in its diameter, which allows to engage / tie fixed end 322, 362 of the lace. However, we can consider other ways to set the lace drum, for example by welding, gluing, a knot ...
    Thus, all of the laces 32, 26 cooperate with a single single drum drum 42. The actuation of the drum drum 42 by means of the motor in a given direction of rotation makes it possible to pull the set of laces 32, 36 for the tightening, and rotation in the opposite direction releases the tension.
    The clamping device 40 further comprises a control unit 55, out of the housing 52, which comprises the electronics / control logic of the motor.
    In FIG. 1, we see the second laces 36 which descend to the drum 42 bypassing the foot, for example through the wall of the outer portion 20 rod. Preferably, the laces are guided in the shoe in individual sheaths, shown in Fig.3. These sheaths 56 will generally be placed in the lateral parts of the shank, for example between the material of the shank (leather, textile, plastic) and its inner lining.
    As indicated above, each of the laces has an end 32i, 36i anchored to a respective edge 22, 28 of the rod 14, where there are eyelets lace passage in conventional shoes. Various means can be envisaged for anchoring these ends, that is to say for firmly fixing the ends on the rod. The ends of the laces could be tied, sewn or riveted.
    But it is advantageous to use a fastening means which provides a firm hold of the end of the lace, while allowing a fine and individual adjustment of the lace tension. One can for example use a banjo type screw, indicated 60 in the figures, that is to say a screw formed of a threaded rod with a head, and comprising at the base of the head a section, generally smooth, with a through hole. The head includes a fingerprint to be screwed or unscrewed by a tool, in particular a screwdriver as shown in Figure 4. Alternatively, the screw head could include a butterfly or other shape facilitating handling with the fingers. The banjo screw cooperates for its screwing with a threaded socket (not shown) fixed in the rod at the desired anchoring point.
    It should be noted that such a fastening means with manual adjustment of the lace tension is extremely advantageous in practice, since it allows a fine adjustment of the tension of each lace, and thus an adaptation of the lacing to the kick of the lace. shoe carrier.
    In Figure 6 we recognize the drum drum in its housing. The housing is partially housed in the lower sole and partially in an insole covering the lower sole. The sheaths 56, which start from the housing 52 and go up towards the tongue, pass through the wall of the rod, that is to say between the outer rod fabric 14i and its inner lining 142.
    The control of the clamping device can be done by means of a button 62 located on the shoe and / or wireless by means of a communicating terminal (not shown).
    The button can be placed at the level of the sole, and can have a rest position, a clamping position and a release position. Alternatively, it is possible to use a simple pusher that will command in sequence a tightening or loosening, the intensity of which depends on the duration of pressing the button.
    The communicating terminal may be for example a mobile phone (smartphone), a PDA, a tablet, etc.
    The wireless connection between the clamping device and the communicating terminal is via a wireless communication that can be Bluetooth type, allowing a simplified connection, a low power consumption in the communication and a wide range of applications. communicating devices compatible. The communication can be done by other networks such as cellular networks, satellites, WI-FI, or others. For this purpose, the clamping device thus comprises a wireless communication module with antenna (not shown), preferably integrated with the control unit 55, for controlling the remote control circuit.
    The communicating terminal implements a program that comprises code means able to control the operation of the electric motor in the desired direction of rotation, depending on whether it is desired to tighten or loosen the laces. This terminal, respectively program, is also configured to store one or more clamping positions for the right and left foot, and this in relation to a given shoe. The shoes are identified in the terminal, which allows to control and store the tightening of lace on several pairs of shoes with the same control terminal. For this purpose, it is possible to measure the clamping force by means of a torque sensor positioned at the axis of the motor or the drum. Alternatively the control unit 55 may be designed to estimate this clamping force. It will also be possible to adjust and memorize, via the terminal, the tightening speed of the motor.
    These different settings will make it possible to memorize settings that correspond to various situations of use of the shoe, for example a tightening adjustment winter and / or summer, or with or without socks, see depending on the thickness of socks ...
    In addition to the motor control and the communication, the control unit 55 may be designed to manage other functionalities (where appropriate with appropriate sensors) and in particular to collect information relating to the user, for example step counting, determination of distances, calories, route, etc.
    It should be noted that the reducing motor assembly is advantageously designed to remain locked in position when the motor is not powered. The immobilization of the motor causes the immobilization of the drum retractor, which prevents the laces from loosening after a clamping operation.
    As indicated above, the battery is preferably of the rechargeable type. You can use a rechargeable Lithium-Polymer type battery (or other), ensuring a long life and impact resistance, and a reduced space in the sole.
    The charging of the battery can be carried out according to different technologies: - by charger, with a flush connector at the level of the sole; with a mechanical recharge device integrated into the soleplate, such as, for example, a piezoelectric device capable of supplying electrical energy from the step; with a non-contact device, for example by induction.
