Definitions

  • the present invention relates to so-called "rigid shell” sports shoes having a upper, in the form of an openable tube on the front, which is connected by lateral joints to a base of shell and which is pivotally stopped rearward by means of its lower edge which is supported on a rim of the shell base, this rim extending between the articulations of the rod at less in the heel area of the shell base.
  • Known sports shoes of this type such as ski boots, have generally, as illustrated by way of example in FIGS. 1 and 2, a rod 1 in the form of openable tube on the front which is articulated, 2, on the sides of a hull base 3, the area of the heel 4, at least, is provided with a rim 5 against which the lower edge 6 of the upper bears 1 thus stopped pivoting backwards.
  • the upper 1 can be opened on the front constitutes, inter alia, thanks to its own rigidity and its rearward locking, the support means posterior of the skier which allows him to control his anteroposterior balance and the transmission efforts towards the heel of the ski.
  • the upper 1 of these shoes, and in particular the dorsal area 7 thereof, is provided relatively undeformable and stiff, as illustrated in FIG. 1, or able to deform elastically, as illustrated in Figure 2.
  • the shell base is, on the one hand, capable of making detectable and amplifying small variations, and on the other hand, is capable of transmitting impulses without loss of force and in a time very short.
  • the upper 1 is made in the form of a tube can be opened on the front with a dorsal area 7 in one piece to present, by its very shape, a great vertical rigidity towards the rear.
  • This vertical rigidity is taken up at the heel 4 of the shell base 3 by means of a flange 5 facing which extends the lower edge 6 of said rod 1, substantially to the joints 2 of the latter.
  • the different rigid constituent parts or high resistance of the shoe are thus perfectly adjusted and locked in pivoting backwards and therefore capable of transmitting the back support of the skier in the area of the heel 4 without loss of force and almost instantly.
  • FIG. 2 which corresponds to the "LOTUS" model marketed in 1979 under the brand RAICHLE, illustrates a shoe capable of providing a some damping of the skier's back support.
  • upper 1 has a transverse slot 8 which extends from its dorsal zone 7 to its lateral joints 2.
  • the present invention proposes to remedy these drawbacks of shoes with rigid shell whose rod can be opened from the front in a simple and efficient way allowing the wearer to modify the initial predetermined stiffness of the rod in the antero-posterior direction to obtain support firmer, and this, reversibly.
  • the invention aims to allow the wearer to adapt the stiffness of the rod backwards in line with its technical level and practice sports planned.
  • the rigid shell sports shoe has a tube-shaped upper that can be opened on the front which has a dorsal area in one piece.
  • the rod is connected by lateral joints to a hull base and is stopped pivoting backwards via its edge lower which rests on a rim of the shell base, this rim extending between the upper joints in the heel area of the base of the shell.
  • the shoe is characterized by the fact that the lower edge of the rod is obtained with an inverted "U" shaped notch which extends in the extension of the dorsal area of the upper, bypassing the heel area and a part of the sides of the hull base, in order to determine reduced lateral spans supported on the edge of the hull base which extends from one to the other of the sides of the latter in bypassing the heel area.
  • This notch is intended to weaken the rod in its dorsal area lower and decrease the support length of its lower edge on the edge of the shell base of the heel as far as its sides and towards its joints, leaving only reduced lateral spans.
  • the rod thus produced has, in a predetermined manner, a certain faculty to be able to deform elastically towards the rear, that is to say an initial stiffness little which is, for example, sought after for the practice of recreational skiing.
  • At least one removable cam is capable, in a first position, to be placed inside the notch in the shape of an inverted "U" to constitute a stop between the latter and the edge of the shell base preventing any elastic deformation towards the back of the rod thus stiffened.
  • the removable cam In a second position, the removable cam is capable of being retracted to leave the interior of the notch free and thus restore the rod to its initial stiffness, that is to say with its predetermined elastic deformation faculty.
  • two removable cams are provided to be put in works inside the notch in the shape of an inverted "U". These cams are located on the side and on the other side of the latter, at the level of the dorsal region of the rod and in correspondence with the rim of the base of shell each between the heel area of the latter and the corresponding flank.
  • the removable cam or cams are rotary cams mounted preferably on rotating shafts, which are provided with an operating means, such as a slot for screwdriver or button.
  • the removable cam or cams are carried either by the rod either by the shell base and comprise a latching and / or stop means intended for them maintain in their first stop position and / or in their second retracted position.
  • Figure 3 shows, in rear perspective view, a ski boot equipped with an adjustable upper stiffness according to the invention.
  • Figures 4 and 5 illustrate the shoe of Figure 3 respectively, with its upper in the position of minimum stiffness (figure 4) and with its rod in position of maximum stiffness (figure 5).
  • FIG 6 shows the shoe of Figure 3 sectional view along the line VI-VI.
  • Figure 7 shows an embodiment detail
  • the shoe shown in Figures 3, 4 and 5 has a rod 1 in the form of a tube which can be opened on the front which has a dorsal area 7 in one piece.
  • the rod 1 is connected to a shell base 3 by side joints 2 and is stopped pivoting backwards via its lower edge 6 which rests on a rim 5 of the shell base 3.
  • This rim 5 extends from continuously from one side to the other of the sides 13, 13 ′, of the hull base 3, bypassing zone 4 of the heel, at least from the joints 2 of the upper 1, the inner edge 6 of which is obtained with a rounded front part 6 '.
  • the rod 1 can thus bend forward without being hindered or stopped in its movement by the edge 5 of the shell base 3 which is tangential to the rounded part 6 '.
  • a notch 10 in the shape of an inverted "U” is obtained in the lower edge 6 of the rod 1 in the extension of the dorsal zone 7 of the latter and extends laterally by its edges 10 'to the at least partially on the sides 13, 13 ′ of the shell base 3.
  • the rod 1 no longer takes back support on the rim 5 of the hull base 3 only by the reduced lateral surfaces 16 of its lower edge 6 which remain between the edges 10 'of the notch 10 and the perpendicular 5' at the point of tangency of said flange 5 with the anterior rounded part 6 ′ of its edge 6, as illustrated more particularly in Figure 7.
  • the rod 1 is thus weakened in its dorsal area 7 and is predisposed to flex elastically backwards when a force directed in this direction is applied to it.
  • two removable cams 8, mounted rotating on rotating shafts 9, are located on the rod 1, approximately on either side of the dorsal zone 7 thereof so as to be able to cooperate, each, with the rim 5 of the shell base 3 between the heel area 4 and the flank 13, 13 ', corresponding to the latter.
  • cams are provided to be able to be implemented in the notch 10 in a first illustrated position in Figures 3, 5, 6 and 7, where they abut against the flange 5 of the shell base 3 and in a second position, illustrated in Figure 4 and in Figure 7 in broken lines, where they retract to distance from said flange 5.
  • the cams removable, each provided with an eccentric arm 18, an operating means such as a slot screwdriver 19, produced on the shaft 9, and a stop means for each position of implementation such that a boss 20 intended to cooperate, by elastic snap-fastening, with a corresponding recess 21.
  • the removable cams 8 are fixed relative to the rod 1 by the plug as a "sandwich" of their eccentric arm 18 between the walls 1 'and 3' of the rod 1 and the shell base 3 and by the interlocking of their rotating shaft 9 which passes through the wall of the rod 1 through a corresponding hole 9 'and this, when the rod 1 is mounted on the shell base 3 using the hinge pins 2.
  • the rod 1 is then able to flex elastically towards the rear, in the direction indicated by arrow 15, and from the lateral bearing surfaces 16 of its lower edge 6 which are in stop on the ledge 5.
  • the removable cams 8 can tilt inside the notch 10 so that their eccentric arms 18 are have, at their end, supported on the rim 5 of the shell base 3, as illustrated on the Figures 3, 5, 6 and 7.
  • the removable cams 8 each constitute a stop which, interposed between the dorsal zone 7 of the rod 1 and the rim 5 of the shell base 3, opposes the elastic deformation of the rod 1 towards the rear.
  • the rod 1 is only capable of bending in a latero-posterior direction directed towards the side of the shoe where the removable cam 8 is retracted. We can therefore increase the anteroposterior stiffness of the dorsal area 7 of the upper 1, favoring one side of the shoe.
  • the invention can be applied to other rigid shell shoes such as ice skates, roller skates, etc ..., and that it can only comprise a removable cam, mounted, preferably in the middle part of the dorsal area 7 of the rod 1.
  • the removable cams 8 can be mounted and fixed on the shell base 3 and come in the stop position, pressing on the bottom of the notch 10 without thereby leaving the frame of the invention.
