Definitions

  • the present invention relates to a sports shoe of the so-called "rigid shell” type and is relates to an adjustable stiffening device intended to modify the characteristics of the sole the shoe, in particular in its longitudinal direction, in order to adapt the overall stiffness of the shoe, and therefore its behavior, for a specific use, especially when it is attached to equipment or accessories necessary for certain sporting practices such as example a ski, a skate, crampons, ... etc.
  • Known sports shoes of this type such as those described in the utility certificate French No. 2,391,666, French Patent Application No. 2,310,719 and the French Patent No. 2 714 800 include adjustable stiffening devices which consist of integrating into the sole or to retain from it at least one rigid element in order to modify the stiffness of the sole, and, consequently, that overall of these shoes.
  • these stiffening devices comprise at least one rigid element removable which extends in the longitudinal direction of the sole, and at least one means assembly of said element with the sole intended to bring them together to achieve their coupling.
  • the adjustment of their stiffness can be done by changing in the sole a rigid element having a stiffness given by another element rigid with a different stiffness.
  • the object of the present invention is to resolve these drawbacks relating to the operations tedious assembly-disassembly and / or storage of unused elements, whether rigid elements or the means of assembling the stiffening devices.
  • Another object of the invention is to propose a stiffening device which is relatively, on the one hand, easy to reach in order to be adjusted, and on the other hand, protected from external contamination and deterioration that may result from the use of the shoe, especially when walking.
  • the invention aims to allow adjustment of the transverse stiffness of the sole simultaneously with an adjustment of the longitudinal stiffness thereof.
  • the invention also aims to optimize manufacturing costs by providing a stiffening device in which at least one rigid element constitutes the inner sole on which rests on the plantar surface of the user's foot.
  • the sports shoe of the rigid shell type is provided with a adjustable stiffening device, intended to modify the characteristics of the sole, which comprises a rigid element extending in the longitudinal direction of the sole and at least one means assembly of the latter with the sole.
  • the rigid element of the stiffening device is mounted freely in a housing made in the sole, this housing being open on the inside of the shoe facing the plantar side of the user's foot.
  • the stiffening device is thus relatively well protected from external contamination and possible damage that may occur during walking. It is also characterized by the fact that at least one assembly means is provided adjustable to intervene between the element rigid and the sole, from a blocking position where it reunites them firmly by realizing their coupling to an unlock position where it leaves them free to debate for the value of a some play left between them.
  • the adjustable assembly means is located in the heel area of the sole and another assembly means, fixed or also adjustable, is used in the sole area.
  • the rigid element can be coupled to the sole in the longitudinal direction thereof at least at two points.
  • the adjustable assembly means is completely inserted into the element rigid through a recess in the latter, and attaches to at least one of the walls of the sole adjoining the rigid element where it remains in engagement, whatever its adjustment position.
  • the rigid element and at least the and / or the means of assembling the stiffening device remain permanently mounted in the sole of the shoe for the operation of adjusting the stiffness thereof.
  • the assembly means being embedded in the thickness of the rigid element, thanks to its insertion into a recess of the latter, its change of adjustment position does not affect the footwear volume of the shoe, in particular vis-à-vis the plantar side of the user's foot.
  • the rigid element is of generally parallelepiped shape and extends approximately from the heel area to the toe area, one at less of its ends situated in correspondence of these zones cooperating with a means adjustable assembly.
  • the rigid element is capable of stiffening the sole of the shoe in its longitudinal direction and practically over its entire length. Given its width, it is also likely to stiffen the sole in its transverse direction.
  • the rigid element has a relatively flat surface on the inside. of the shoe facing the plantar side of the user's foot and constitutes, at least partially, the inner sole of the shoe.
  • the recess in which is inserted the means of assembly is determined taking into account variations in the locking position at that of unlocking the latter relative to the flat surface of the rigid element which serves support for the user's foot. More precisely, the assembly means always remains located below this flat surface, whether it is oriented vertically or transversely to the element rigid which it crosses and then engages in the sole.
  • the sports shoe schematically illustrated in Figures 1 and 2 has a shell rigid 1 and a sole 2, shown along their outline, and is provided with a device adjustable stiffener 3 which is integrated in its sole 2.
  • This device comprises, on the one hand, a rigid element 4 of generally parallelepiped shape which extends in the longitudinal direction of the sole 2 approximately from the heel area 5 up to the end zone 6, and on the other hand, a first assembly means 7 and a second fixed assembly means 8, these means 7 and 8 cooperating with the rear ends 9 and anterior 10 of the rigid element 4 and the sole 2.
  • the rigid element 4 is introduced into a housing 14 produced in the sole 2 on the inside of the shoe where the user's foot is housed.
  • a fixed assembly means 8 that is to say non-adjustable, which is preferably used in the area of the toe 6 of the sole because this area 6 is difficult to access from the inside, which this is not the case for the heel area 5.
  • This fixed assembly means 8 consists, in this example, of a fitting of a part 22 forming a tenon in a portion 23 forming a mortise.
  • this means of assembly fixed 8 can be replaced by another adjustable assembly means 7 or by other means such as screws for example which can be passed through the sole 2 from outside from the walking surface 2 'of the latter.
  • the housing 14, open on the inside of the shoe facing the plantar face 11 of the user's foot (shown in broken lines in Figure 2) is made in the thickness of the sole 2 to freely receive the rigid element 4.
  • the contour of the housing 14 is provided substantially larger than the contour of the rigid element 4 so that there remains a certain clearance 12 between them in the transverse direction and longitudinal.
  • the housing 14 is preferably adjusted with the thickness of the rigid element 4 so that the upper surface 4 'of the latter which is facing the plantar face 11 of the user's foot is substantially the same level as the horizontal part 24 of the sole 2 which surrounds it and on which the foot.
  • the rigid element 4 then constitutes the equivalent of a rigid internal sole.
  • the adjustable assembly means 7 intervenes between the rigid element 4 and the sole 2 by fully inserting through a recess 13 in the rigid element 4 and fixed on the sole 2 where it bears to apply on the rigid element 4, in the position of blocking, in a vertical direction 15 directed from top to bottom as shown in the figure 4.
  • the adjustable assembly means 7 consists of a cylinder comprising an eccentric cylindrical part 17 situated between its two ends 18, 19, which are engaged in bearings 18 ', 19', corresponding made in the sole 2 on either side of the housing 12 into which is introduced the rigid element 4.
  • the assembly means adjustable 7 is axially transverse to the rigid element 4 and one of its ends 18, 19, is provided with an operating means 20, such as a screwdriver slot, accessible from the outside, on a side of the sole 2. It is noted that this lateral arrangement of the operating means 20 of the assembly means 7 relatively limits the risks of deterioration of the latter which may result from the use of the shoe when walking and is easily accessible requiring no manipulation or prior operation such as heaving or opening the shoe to modify the overall stiffness of the sole 2.
  • the fixed assembly means 8 consists of a interlocking over the entire width of the front end 10 of the rigid element 4 and the means adjustable assembly 7 acts, in the locked position, over a large width of the end posterior 9 of said rigid element 4, via its eccentric cylindrical bearing 17.
  • the adjustable stiffening device 3 is capable, on the one hand, of providing a high rigidity at the base 2 both in the longitudinal direction and in the transverse direction when its rigid element 4 is coupled with, and on the other hand, to tolerate a certain overall deformability of the sole 2 when the rigid element 4 is free to debate transversely in the housing 14 of the latter for the value of the predetermined clearance 12.
  • the device adjustable stiffener 33 differs from that of FIGS. 1 to 4 which precede by the shape given to the rigid element 34 with its recess 43, and by its fixed assembly means 38 which is located in the area of the toe 6 of the sole 2.
  • the rigid element 34 consists of a "U" shaped profile mounted at upside down so that its horizontal part between its branches 34 'has a surface upper 4 'which extends at the level of the horizontal part 24 of the sole 2 which surrounds it and on which rests the user's foot.
  • its recess 43 in which fits the adjustable assembly means 7, is formed by a bore corresponding to the cylindrical ends 18 and 19 of the joining means 7.
  • the joining means fixed 38 the latter consists of a pin which is mounted transversely in the sole 2 and the branches of the rigid element 34.
  • each adjustable assembly means 37 can, as shown in FIG. 8, consist of a half of the adjustable assembly means 7 described above and include a scope cylindrical 18 or 19 with partial eccentric cylindrical bearing 17 so as not to engage with a branch 34 ′ only, it being understood that each cylindrical bearing surface 18 and 19 is then provided with an operating means 20.
  • This variant of construction offers the possibility of modifying the overall stiffness of the sole 2 in the longitudinal direction and transverse as before, but with the possibility of additional adjustment making it possible to differentiate the transverse stiffness from one side to the other of the sole 2, at the level of the two adjustable assembly means 37. This possibility is offered by placing only one of the two adjustable assembly means 37 in the locked position.
  • the device adjustable stiffener 53 is provided with two adjustable assembly means 57 which are oriented vertically on the heel area 9 of the rigid element 54, and of a fixed assembly means 8 of the tenon 22 - mortise 23 type transverse to the end region 10 of the rigid element 54.
  • This last 54 mounts in a housing 64 made in the sole 2 taking into account its thickness so that its upper surface 4 'reaches the level of the horizontal part 24 of the sole 2 which serves as a reference for determining the position of the surface on which comes rest the user's foot.
  • the rigid element 54 is obtained with a recess 63 into which the adjustable assembly means 57 are inserted and at the bottom of which the latter are applied, in the blocking position, visible in FIG. 10, according to a vertical direction directed from top to bottom against the sole 2.
  • the recess 63 in fact belongs to a bowl which penetrates, taking into account its depth, in a corresponding clearance 51 from the sole 2.
  • the adjustable assembly means 57 which consist in this example in simple screws, remain located below the upper surface 4 'of the rigid element 54 whether they are in the locking or unlocking position.
  • the adjustable assembly means 77 used with the rigid element 74 consists of a twistlock system 75 cooperating with two retaining and tightening 78 which are fixed in the sole 2.
  • the twist lock 75 placed in a recess 83 of the rigid element 74, is notably obtained with two circular lights 71 opposed by relative to the axis of rotation of latch 75 which extend over an arc of 90 °, and through which pass the retaining and clamping members 78. These lights each have a circular ramp 80, illustrated in section in FIG. 15, on which the head 79 of each retaining and tightening member 78 is supported.
  • the rigid element 4, 34, 54, 74, adjustable stiffening devices 3, 33, 53, 73 can be connected to the sole 2 only using adjustable assembly means 7, 37, 57, 77, that is to say without using fixed assembly means.
  • the rigid element 4, 34, 54, 74 may have other forms than those which come be described, be of full section, hollow or with an open profile, and may not extend longitudinally only over a portion of the length of the sole. Also, it can be of reduced width or, for example, simply consist of a cylinder.
  • adjustable assembly means can be provided only at the end 6 or at the heel 5 of sole 2.
  • Figures 16 and 17 illustrate a fifth embodiment of a stiffening device adjustable 93 in which the adjustable assembly means 97 comprises a movable cleat 98 on a threaded piece 99 in the direction of the rigid element 94 on the side of a recess 103 of which is provided the latter.
  • This recess 103 is delimited by an inclined face 103 'against which it is locks in a given adjustment position.
  • the adjustable assembly means 97 is inserted into the recess 103 and is fixed on the sole 2 by means of the threaded piece 99.
  • the latter has its two ends 100, 101, retained in corresponding bearings 100 ', 101', obtained in the sole 2, one, 100 ', in the wall heel 5 thereof, and the other, 101 ', in a protrusion 110 produced in the housing 104 where the rigid element 94 is mounted.
  • the rigid element 94 is provided with an empty space at the location opposite the protrusion 110, which is advantageously obtained by using a "U" section profile as in the realization described in figure 5.
  • the rigid element 94 has a flat surface 4 'on the side inside of the shoe and at least partially constitutes the internal sole. He is retained by its end 10 in the area of the toe 6 of the sole 2 by means of a means fixed assembly 8 consisting of a socket type tenon 22-mortise 23, and by its end 9 in the heel area 5 using the adjustable assembly means 97 by through the cleat 98 which is provided with a bevel 98 'to act as a wedge blocking on the inclined face 103 'delimiting the rigid element 94 on the side of its recess 103.
  • the bevel 98 'of the cleat 98 is oriented so as to overlap the top down on the inclined face 103 ′, and the threaded piece 99 is locked in translation relative to the sole 2 by its two ends 100, 101, respectively by a stop ring 105 and by a shoulder 106.
  • the coupling of the rigid element 94 with the sole 2 results from a significant thrust of the cleat 98, as indicated by the arrow 119, in direction of the tip 6 of the sole 2 which has the consequence of constraining the latter in its longitudinal direction and, thanks to the bevel 98 'which is applied to the inclined face 103' of the rigid element 94, to simultaneously produce a force tending to press the latter on the bottom of the housing 104.
  • the adjustable stiffening device 93 thus allows, depending on the clamping force applied to the operating means 20, to put the sole 2 more or less in a state of tension without the relative position of the rigid element 94 relative to its housing 104 not exchange.
  • the rigid element 94 is provided with an opening 118 in the form of U overturned on the side where the threaded piece 99 of the adjustable assembly means 97 passes. It is thus very easy to assemble or disassemble the rigid element 94.
