Definitions

  • the invention relates to roller skates and more particularly roller skates with in-line wheels.
  • the invention relates more particularly to the so-called aggressive shoe intended for acrobatic figures, these pads having important requirements in terms of protection of the joints.
  • skates There is also a third family of skates that could be described as hybrid because they include a removable boot. In some cases, these slippers are intended to walk but it is not about real shoes.
  • An independent shoe shoe pad is shown in the document DE-U-93 07 747 . It comprises a hull provided with three simple ratchet clamps identical to each other. Between the clamp of the lower leg and the clamping device placed on the instep, the shell has on each side a wide notch, to facilitate the flexion of the lower leg.
  • the shell which constitutes the rigid structure, is not only discontinuous between the medial side and the lateral side but also between the zone of the instep and the zone of the lower leg.
  • the tightening of the instep is at most the two portions of the shell come into contact with one another.
  • the user will feel discontinuities of support of the rigid elements between the medial portion of the shell and the lateral portion.
  • the notched strap designed to connect these two portions is thin, more flexible and, being set back from the shell, it does not rest against the instep of the user.
  • the user will feel a discontinuity in the pressure exerted by the hull on his foot between the zone of the instep and the area of the lower leg. It is however established that all sensory sensors placed on the surface of the skin may be necessary for the prevention of injuries due to excess of joint capacities. In this sense, the pressure discontinuities exerted by the rigid structures of a pad on the foot of a user endanger the joint.
  • Such a pad also does not provide good protection of the ankle joint during lateral flexions of the leg because of the large notches the lateral strength of the collar is not sufficient.
  • a roller skate whose shoe is an integral part of said shoe is described in the application EP 891 794 . It includes a shell bottom and a hinged collar along the axis of the ankle joint. This shoe nevertheless has the disadvantage of limiting the movements of the foot other than forward bending, which is ensured by the articulation of the collar. On the other hand, the bending movement generated by the pivot of the collar on the bottom of the shell lacks continuity and fluidity. With this type of pad, a skater who wishes to give more amplitude to his movements has no alternative but to loosen all the clamping mechanisms of his pad. In doing so he allows his foot more possibility of movement, but he also loses continuous contact with the rigid shell and therefore he does not benefit at any time from the support that the hull could bring him.
  • the first object of the invention is to provide an aligned roller skate which allows the use of an independent shoe, which provides good protection of the ankle joint.
  • the pad provided by the invention must also be inexpensive to manufacture and easy to use.
  • an in-line roller skate for receiving a shoe, which shoe comprises a longitudinal frame on which a plurality of wheels are fixed, a base whose upper surface is provided to support the sole of the shoe. walking of said shoe, a rear quarter whose upper part is equipped with a comfort element surrounding the lower leg.
  • the pad also includes a forefoot clamping device that presses the front portion of said shoe against said upper surface of the base, a lower leg clamp clamping said upper portion against the lower leg and a neck restraint.
  • a foot exerting a force on the instep portion of said shoe and having a frame providing continuous support from a lateral side to a medial side from the instep area to the upper portion of the foot; skate.
  • the frame is made of a rigid plastic material and comprises two main parts.
  • the first called plastron
  • the plastron substantially surrounds the entire area of the instep of the user and ensures the continuity of support maintenance from the internal lateral side to the external lateral side.
  • the plastron has a width of at least 3 cm, so as to distribute the large clamping force exerted by the lever mechanism of the instep holding device.
  • the second of these main parts called tab, is attached to the chest by means of a foot, from which it widens and curls to match the front of the lower leg of the user.
  • the tongue extends substantially at the same level as the top of the upper part of the pad and thus ensures the continuity of support maintenance from the area of the instep to the top of the pad.
  • Under the frame is attached padding slightly wider than the frame itself, so as to avoid direct contact of the frame with the user.
  • the instep holding device also comprises adjustment means connecting the plastron to the inner side of the quarter and clamping means connecting the armature to the outer side of the rear quarter.
  • the clamping means comprise a toothed strap, a ratchet of the toothed strap and a drive lever of the toothed strap. This considerably increases the holding force of the instep area.
  • the adjustment means allow them to accurately position the front plate before the tightening takes place.
  • Another object of the invention is the provision of an assembly consisting of a skid and an independent shoe providing comfort and protection of the ankle joint equivalent to those offered by a conventional "aggressive" skate .
  • an assembly comprising an aligned roller skate according to claim 1 and an independent shoe, which shoe comprises a longitudinal frame on which a plurality of wheels are fixed, a base whose upper surface is provided to support the outsole of said shoe, a rear quarter whose upper portion is equipped with a comfort element surrounding the lower leg.
  • the pad also includes a forefoot clamping device that presses the front portion of said shoe against said upper surface of the base, a lower leg clamp clamping said upper portion against the lower leg and a neck restraint.

  • the central zone is in the form of a plastron 22 while the outer zone is constituted by a notched strap and d a locking mechanism 37 with ratchet.
  • the plastron 22 has, inter alia, the effect of distributing the clamping pressure of the strap and allow a greater clamping force without generating pain for the user.
  • the figure 11 has an equipped skate, an alternative version of the plastron 22.
  • the plastron 22 extends to the top of the shoe and it is equipped with passage means of the lower leg strap 21.
  • the part The upper part of this plastron plays the role of a fourth rigid element having the same function as the outer and inner wings. Although it is not directly connected to the base like the wings 10, 11 and 12, it is indirectly connected via the instep strap. When the strap is tightened against the foot of the user, the connection of the strap to the buttress is relatively rigid.
  • Such a plastron may be equipped with means for bending, such as weakened areas. But it can also be equipped with means protecting the user from hyperflexion, such as for example one or stops.
  • the pad according to the second embodiment described herein is intended to be used with any shoe, including a skateboard shoe or a sports shoe in general. Due to the presence of the cushion cushion 16, this shoe will be low or semi-rising.
  • the cooperation between the PCT type instep strap and the opening 15 formed in the rear buttress 4 guarantees the optimal positioning of the lower leg of the user. Indeed, if the user has a shoe whose sole is very wide or has significant overhangs, the soleplate may overflow through the opening 15 and the back of the lower leg of the user will be pressed against the wing rear 10.
  • FIGS. 8a, 8b and 8c show the behavior in lateral flexion of a pad according to the invention. Each of these figures represents a partial rear view of the pad at different times of use of the pad.
  • the figure 8b shows the pad flexed sideways to the right.
  • the inner wing is offset to the left, the collar pivots about the hinge axis 9 and causes the bending to the left of the outer wing.
  • the figure 8c shows a symmetrical behavior of the pad during a bending to the left.
  • the Figures 9a and 9b show in perspective two views of the back quarter.
  • the collar In the lower part of the rear wing are drilled a plurality of holes arranged in a vertical line. So the collar can take different positions, the lower the collar will be ( Fig. 9b ), the more the user will have a great laxity of movement.
  • the pad can be adapted optimally to the morphology of the user. A person of very large size will prefer the high setting ( Fig. 9a ) while another will opt for a lower setting.
  • the inner and outer wings are also each equipped with a plurality of holes arranged in a vertical line. These various holes are used for fixing the internal buttress element in different vertical positions for a morphological adaptation of the pad to the user.
  • FIGS. 10a and 10b show an alternative embodiment of the adjustment means of the clamping plane of the collar.
  • the pivot axis of the collar 46 on the rear quarter is not placed in the clamping plane, and the latter can be placed in two positions. In the high position, the clamping plane is above the hinge axis, while in the lower position it is below the axis. The passage from the high position to the low position is done by the 180 ° pivoting of the collar around the axis of articulation thereof.
  • the figure 12 presents another embodiment which does not form part of the invention in which the collar 27 is a strap fixed on the rear wing 10.
  • the point of attachment of the strap which is in the clamping plane of the collar 27 can be moved vertically according to the desired rigidity. It is of course possible to use in this embodiment the plastron described in FIG. figure 11
