Definitions
- the invention relates to roller skates and more particularly to roller skates with aligned wheels.
- the invention relates more particularly to the so-called aggressive skate intended for acrobatic figures, these skates having significant requirements in terms of protection of the joints.
- skates There is also a third family of skates that could be called hybrid because they include a removable liner. In some cases, these slippers are designed to work, but they are not real shoes.
- An independent walking shoe skate is shown in document DE-U-93 07 747. It comprises a shell provided with three simple ratchet tightening devices which are identical to each other. Between the lower leg clamping device and the clamping device placed on the instep, the shell has a wide notch on each side to facilitate flexing 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 instep area and the lower leg area.
- the two portions of the shell come into contact with one another.
- the notched strap provided to connect these two portions is fine, more flexible and, being set back from the shell, it does not bear against the instep of the user.
- the user will feel a discontinuity in the pressure exerted by the shell on his foot between the instep area and the lower leg area. It is however established that all the sensory sensors placed on the surface of the skin may be necessary for the prevention of injuries due to the overstepping of joint capacities. In this sense, the pressure discontinuities exerted by the rigid structures of a skate on the foot of a user endanger the joint.
- Such a pad also does not provide good protection of the ankle joint during lateral bending of the leg because of the wide notches the lateral holding of the collar is not sufficient.
- a roller skate the shoe of which is an integral part of said skate, is described in application EP 891 794. It includes a shell bottom and a collar articulated along the axis of the ankle joint. This shoe nevertheless has the drawback 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 skate, a skater who wishes to give more amplitude to his movements has no other solution than to loosen all the tightening mechanisms of his skate.
- the first objective of the invention is to provide an inline skate which allows the use of an independent shoe, which provides good protection for the ankle joint.
- the pad provided by the invention must also be inexpensive to manufacture and easy to use.
- an inline skate for receiving a shoe, which skate comprising a longitudinal frame on which a plurality of wheels are fixed, a base whose upper surface is provided to support the tread. of said shoe, a rear quarter, an upper part of which is equipped with a comfort element surrounding the lower leg.
- the shoe also includes a forefoot tightening device pressing the front part of said shoe against said upper surface of the base, a lower leg tightening device tightening said upper part against the lower leg and a neck support device.
- -foot exerting a force on the instep part of said shoe and comprising a frame ensuring continuous support from a lateral side to a medial side from the instep area to the upper portion of the skate.
- the frame is made of rigid plastic material and has two main parts.
- the first called plastron
- the breastplate has a certain width, of at least 3 cm, so as to distribute the large clamping force exerted by the lever mechanism of the instep support device.
- the second of these main parts called the tongue
- the tongue is attached to the plastron by means of a foot, from which it widens and curls in order to correspond to the front face of the user's lower leg.
- the tongue extends substantially at the same level as the top of the upper part of the skate and thus ensures the continuity of the support maintenance from the instep area to the top of the skate.
- Under the frame is fixed a padding slightly wider than the frame itself, so as to avoid direct contact of the frame with the user.
- the instep support device also comprises adjustment means connecting the faceplate to the internal side of the quarter and clamping means connecting the frame to the external side of the rear quarter.
- the tightening means comprise a notched strap, a catch for retaining the notched strap and a lever for driving the notched strap. This considerably increases the holding force of the instep area.
- the adjustment means allow them precise positioning of the faceplate before tightening is carried out.
- Another objective of the invention is to provide a set consisting of a skate and an independent shoe ensuring comfort and protection of the ankle joint equivalent to those offered by a conventional "aggressive" skate .
- an assembly comprising a roller skate and an independent shoe, which shoe comprising a longitudinal frame on which a plurality of wheels are fixed, a base whose upper surface is provided to support the sole of said shoe, a rear quarter of which an upper part is equipped with a comfort element surrounding the lower leg.
- the shoe also includes a forefoot tightening device pressing the front part of said shoe against said upper surface of the base, a lower leg tightening device tightening said upper part against the lower leg and a neck support device.
- - foot exerting a force on the instep part of said shoe and comprising a frame ensuring continuous support from a lateral side to a medial side from the elbow area to the upper portion of the skate.
- the frame is made of rigid plastic material and has two main parts.
- the first called plastron
- the second of these main parts called the tongue
- the tongue is attached to the plastron by means of a foot, from which it widens and curls in order to correspond to the front face of the user's lower leg.
- the tongue extends substantially at the same level as the top of the upper part of the skate and thus ensures the continuity of the support maintenance from the elbow area to the top of the skate.
- the rear quarter includes an opening whose upper edge is substantially horizontal.
- the shoe includes in its rear part a sidewalk protruding. When the shoe is inserted into the shoe, the sidewalk cooperates with said upper stop and prevents any movement of the heel of the shoe upwards.
- the instep holding device is equipped with a tightening assistance mechanism comprising a pawl and a lever.
- the invention also relates to a skate intended to receive any shoe and in particular a skateboard shoe or any type of sports shoe in general.
- a skateboard shoe or any type of sports shoe in general Each shoe having its own characteristics, sole height, lateral overhangs thereof, etc., it is difficult to guarantee the correct positioning of the user's foot relative to the skate and to reproduce this positioning whatever the shoe used.
- the objective of the invention is to provide a skate that does not have the aforementioned drawbacks.
- the objective of the invention is to provide a shoe which allows the multidirectionality of deformation of the rod, in particular in order to accompany the lateral and medial flexions of the user's lower leg.
- the objective of the invention is also to provide a pad which allows greater continuity of the deformations of the rod.
- the objective of the invention is also to provide a skate which allows the skater to be in contact at all times with the rigid elements of the shell without this contact being a hindrance to the movements of the foot.
- the objective is finally to provide a skate which guarantees the correct positioning of the foot whatever the shoe used.
- the object of the invention is also achieved by providing a pad intended to receive the foot, the ankle joint and the lower leg of a user.
- Said skate comprising:
- a collar encircling all the upper parts of the rigid elements in a clamping plane perpendicular to the axis of the user's leg.
- the collar is fixed to the rest of the structure so that it can pivot around an axis perpendicular to the axis of articulation of the ankle and located lower than the tightening plane of said collar .
- adjustment means make it possible to vary the height of the clamping plane of said collar, in order to vary the rigidity in lateral and anterior bending of the pad.

- Figures 1 and 2 respectively show a front perspective view and a rear perspective view of a skate according to a preferred embodiment of the invention.
- an independent shoe 30 is inserted into the skate while in FIG. 2 it is removed therefrom.
- the shoe 1 comprises a footwear part 2 fixed by detachable fixing means on a chassis 3 equipped with a sliding element.
- the sliding element consists of two wheels mounted in line in the longitudinal plane of the chassis.
- the skate in question is particularly suitable for the practice of aggressive skating, the choice of a chassis with two wheels is not limiting and one can envisage a chassis with three, four or five wheels. It is also possible to attach an ice skate blade or a mini ski.
- the footwear part includes a base 5 intended on the one hand for fixing the chassis and on the other hand for supporting the user's foot.
- the bottom surface of the base is wider than the frame attached to it. So when the chassis is fixed, a medial sliding surface and a lateral sliding surface are defined. These medial and lateral gliding surfaces each comprise a co-planar front portion and a rear portion of the gliding plane of the skate. During some figures, the user can use one or other of these sliding surfaces to slide on a rail or a ramp.
- the base 5 is extended on the lateral side and the medial side by two substantially vertical edges which ensure the lateral stability of the shoe in the shoe, a lateral edge 6 and a medial edge 7.
- the upper surface of the base is substantially flat and comprises a removable heel 31 making it possible to raise the heel of the user substantially. Since the skate is likely to be used with independent shoes that do not necessarily have the same heel heights and that the heel height plays an important role in the maneuverability of the skate, it is preferable to provide a removable heel. However, it is also conceivable to provide that the heel is not removable.
- the heel 31 is made of a material in a shock absorbing material, such as for example a high density foam, so as to protect the user when receiving jumps.
- the footwear part comprises a rigid rear quarter 8 fixed on the rear part of the base 5.
- This quarter shown in FIG. 3 comprises a rear buttress 9 from which three rigid elements 10, 11, 12 come from.
- These elements extend to the upper part of the skate and include an external wing 11 supporting the external side of the user's lower leg, an internal wing 12 supporting the internal side of the lower leg and a rear wing 10 supporting the rear part of the lower leg.
- These three wings are made of plastic and form with the rear buttress a single piece: the rear quarter 8. The structure of this piece associated with the choice of material gives it a certain lateral flexibility both towards the internal side and towards the external side.
- the wings may be envisaged in the context of the invention to provide the wings as separate parts fixed removably or not to the rear buttress.
- the external wings 11 and internal wings 12 shapes which are substantially different from each other so as to differentiate their behavior in flexibility.
- An opening 15 is formed in the rear buttress 9, at the base thereof. This opening improves flexibility towards the rear of the rear quarter 8.
- the stiffness bar 32 Between the opening 15 and the front edges of the rear quarter, this comprises a very rigid zone called the stiffness bar 32.
- the bar present on the lateral side as on the medial side ensures the lateral stability of the user's leg and effectively protects the ankle joint from sprains.
- the lateral bar, respectively the medial bar is extended by the lateral wing, respectively by the medial wing.
- the thickness of plastic material used to manufacture the rear quarter being lower at the level of the wings than of the bar, the rigidity of the quarter 8 is progressive, decreasing regularly from the bottom to the top.
- the collar 27 is fixed, by a screw 28 on the rear side of the skate, to the rear wing 10 or to the rear buttress 9. It comprises a back 17, an internal arm 18 and an external arm 19.
- a low clamping device leg 21 extends the arms so that the collar tightens the upper part of the skate, against the user's lower leg.
- the position of the arms 18, 19 and the lower leg straps define a substantially horizontal clamping plane.
- Means for vertical adjustment of the clamping plane are provided in the form of a plurality of holes formed in the rear wing and arranged in a vertical line.
- the lower leg tightening device 21 comprises two flexible straps, one of these two straps, the medial strap 48, is fixed to the internal arm of the collar while the other, the lateral strap 50, is fixed to the external arm .
- a lateral loop 47 and a medial loop 49 are fixed on the tongue 29.
- the lateral strap 50, respectively the medial strap 48 passes through the lateral loop 47, respectively the medial loop 49, and can be folded in on itself, Velcro type attachment means then ensuring the retention of the strap.
- the lower leg tightening device allows, in addition to tightening, the very precise positioning of the tongue. This last additional function is also achievable independently of the actual tightening.
- the user can choose and ensure that the tongue 29 is maintained in the chosen position. In practice, to save time the user can be satisfied to release only one of the two straps before you can take your foot off the skate.
- a cushion 16 is inserted into the space formed by the three wings, it comprises a shock-absorbing material of the foam type.
- the cushion cushion 16 extends only in the region of the lower leg of the user. It is held at the rear wing 10 by means of a screw.
- the same screw fixes the collar 27 and the cushion 16 to the rear quarter 8.
- the cushion is also directly attached to the collar 27, at the ends of the arms 18 and 19. In the same way that it is possible to adjust the height of the lower leg tightening device, the position of the cushion 16 can be adjusted in height in order to adapt it to different morphologies.
- FIGS. 4a, 4b and 4c show the behavior in lateral flexion of a skate according to the invention. Each of these figures represents a partial rear view of the skate at different times during the use of the skate.
- Figure 4b shows the pad subjected to lateral bending to the right.
- the internal wing is offset to the right, the collar pivots around the articulation axis, visible by the screw 28, and causes the external wing to flex to the left.
- the external notch 13 which separates the external wing 11 from the rear wing 10 allows the bending of the external wing 11.
- the presence of the collar 27 which surrounds the upper part of the skate causes the bending of the internal wing 12 to the right.
- Figure 4c shows a symmetrical behavior of the skate when bending to the left.
- These softening slots can be horizontal, vertical or oblique.
- the rear quarter 8 associated with the collar 27 allows the skater to be in contact at all times with the rigid elements of the skate, even when bending on the sides, without this contact being a discomfort for movement.
- the footwear part also includes a forefoot tightening device 33.
- a forefoot tightening device 33 This is in the form of a flexible strap fixed on one side of the base 5 at the area occupied by the portion of the user's foot. which surrounds the metatarsophalangeal flexion zone. On the other side, a loop for the passage of the strap is attached.
- the strap is equipped with fastening means such as velcro straps.
- the strap is optionally lined with a comfort element comprising a foam-like material.
- the means for fixing this strap and the buckle do not project laterally from the outer and inner rims of the base.
- the forefoot strap and its fixing means are protected from damage caused by the friction of the exposed parts of the skate against concrete, bitumen or any other surface on which the sport of "aggressive skating" will be practiced.
- Several anchoring zones of the forefoot clamping device are provided so as to modify the longitudinal position of the clamping device.
- the footwear part 2 includes a instep support device 23.
- the adjustment means comprises an anchoring zone consisting of a plurality of threaded inserts anchored in the rear quarter, preferably on the internal side of the latter, an adjustment strap fixed by means of a screw. one of the threaded inserts.
- the free end of this adjustment strap 34 includes a plurality of aligned holes. By means of an enlarged head screw 35, the free end of the adjustment strap is fixed to the faceplate 22.
- the enlarged head of the screw must allow it to be handled directly by the user, without the assistance of any tool.
- the adjustment means allow the centering of the plastron on the instep of the user according to its morphology and the shoe that it uses.
- the plurality of threaded inserts provided in the rear quarter allows the height adjustment of the faceplate.
- the clamping means proper On the side opposite the adjusting means are the clamping means proper. Unlike the other two means of tightening the footwear, it is assisted by a lever mechanism. It comprises an anchoring zone consisting of a plurality of threaded inserts anchored in the rear quarter, preferably on the external side of the latter, a tightening strap 36 fixed by means of a screw to the one of the threaded inserts and a tightening assistance mechanism.
- the free end of the tightening strap is provided with notches intended to cooperate with a pawl of the mechanism 37.
- the said mechanism also includes a lever whose role is assist the user when tightening.
- the mechanism 37 has a button which releases the pawl from its engagement with the notches so as to loosen it.
- the faceplate 22 is part of a frame 24 extending continuously from the internal side to the external side.
- a slot 25 is formed in the central portion of the front plate, this slot makes it possible to soften said frame when the user is brought to bend his leg forward.
- the frame has a certain width, at least greater than 3 or 4 cm.
- Under the frame is fixed a padding 26.
- the padding 26 is slightly wider than the frame 24 and as the latter extends continuously from the inner side to the outer side.
- the padding 26 which does not include any discontinuity from the top to the bottom is visible through the slot 25.
- the skate according to the invention favors tightening at the instep compared to tightening the lower leg and the forefoot. All the clamping force developed by the lever is distributed over the surface of the frame, that is to say both continuously from the internal side to the external side and over the great width of the frame. On the other hand the padding 26 protects the instep of the user against too strong contact with the frame.
- the frame 24 also comprises a tongue 29.
- This tongue 29 is made of the same material as the faceplate 22.
- the tongue and the faceplate are one and the same piece. Due to the rigidity, the plastron 22 and the tongue 29 are part of the skid structure parts, which also include the base and the rear quarter.
- the tongue 29 comprises a foot 38 which attaches it to the plastron in the center of the latter. From this foot, the tongue widens and bends so as to wrap the user's lower leg.
- the padding 26 extends under the tongue to leave no portion of the tongue in contact with the user's leg.
- the tongue 29 in its own way performs a function similar to that performed by the three wings 10, 11 and 12 by accompanying the bending of the leg forwards. On the other hand, it improves the quality of the wrapping of the lower leg by the rigid elements of the skate.
- the lower leg clamp is operated, rather than simply pressing the two wings, lateral and medial, against the lower leg, the latter, by means of the tongue 29, also exerts a force pushing the bottom leg against the rear wing.
- the lower leg tightening device comprises a flexible strap fixed to the outer arm of the collar.
- the free end of this strap passes through a loop fixed to the internal arm of the collar and fitted with Velcro type attachment means ensuring the retention of the strap.
- a loop fixed on the tongue 29 allows a sliding connection between the strap and the tongue 29.
- the shoe shown in Figure 2 has a walking sole and a low upper.
- a sidewalk 40 projects. This sidewalk is intended to cooperate with the upper edge of the opening 15.
- the instep area of the shoe is devoid of bulky rigid elements so as to avoid any pain when the frame 24 is in abutment thereon.
- FIG. 5 describes an alternative version of the base fitted to a skate according to the invention.
- the base includes two independent shoes 43, 44.
- these shoes have sliding characteristics different from the base.
- the sliding characteristics of the shoe or the base correspond to the ease that these elements offer to allow sliding on metal or concrete. These characteristics are linked to the very nature of the material and to another extent to the shape of the part.
- the shoes have sliding characteristics which are also different from those of the material constituting the chassis and in particular from those constituting the central arch of the chassis.
- the shoes 43, 44 each include a horizontal portion which is interposed between the base and the chassis.
- the lower surfaces of these shoes protrude from the lower surface of the base so that when the user slides longitudinally, only the horizontal portions of the shoes are in contact with the metal rail or the edge of the concrete.
- the shoes On each side of the horizontal portions, the shoes have vertical portions which also project from the surrounding areas of the base.
- the hooves are made of polyacetal, a material that promotes sliding.
- the base and the frame are made of polyamide loaded with fibers in order to increase its resistance.
- the skate according to the invention multiplies the possibilities of figures because the user can either roll on the wheels, or slide longitudinally on the shoes at a rapid speed, or slide transversely on the central arch of the chassis at a reduced speed, from made of the higher sliding resistance of the chassis material.
- FIG. 6 shows the detail of the fixing of the rear quarter 8 to the base 5.
- the rear quarter 8 comprises a horizontal plate 41 placed on the rear part of the upper surface of the base 5.
- the rear quarter 8, the base 5 and the chassis are held together by a single screw associated with a threaded insert.
- the threaded insert includes a horizontal flange resting on the bottom of the rear quarter board and a threaded sleeve which is inserted in an oblong opening 42, which passes through the board 41.
- a screw screwed from below the chassis ensures the removable fixing of the rear quarter 8 with the rear parts of the base and the chassis.
- a similar fixing device secures the front part of the chassis to the base.
- the oblong opening 42 is oriented in the longitudinal direction and makes it possible to modify the position of the rear quarter 8, so as to adapt the shoe for several sizes.
- the spacing of the two fixing means is compatible with the UFS, the technical data of which are described in patent application S.N. 09/779 843.
- Figure 7 shows a shoe 1 according to a second embodiment of the invention. It consists of a chassis 3 receiving a plurality of wheels 4, a base 5 and a part full foot.
- the base 5 is intended on the one hand for fixing the chassis 3 and on the other hand for supporting the foot of a user. It further comprises sliding plates 45, these plates come directly from the base 5 itself and form therewith a single piece. Of course, these plates can also be made from a material different from that of the base 5 in order to modify the sliding coefficient of the skate.
- the foot portion of the shoe 1 is designed to receive the foot of a user equipped with a low or semi-rising shoe of the skateboard shoe type (not shown). It includes a front strap 33, fixed on the base 5 and covering the metatarsophalangeal flexion zone. To allow the fitting of the footwear to the morphology of the user, two pairs of anchoring points of the front strap on the base are provided on the base 5.
- the footwear also includes a rigid rear quarter 8 fixed on the rear part of the base 5. This quarter comprises a rear buttress 9 from which three rigid elements 10, 11, 12 come from.
- These elements extend to the upper part of the skate and include an external wing 11 supporting the external side of the user's lower leg, an internal wing 12 supporting the internal side of the lower leg and a rear wing 10 supporting the rear part of the lower leg. These three wings are separated from each other by an external notch 13 and by an internal notch 14. These three wings are made of plastic and form with the rear buttress a single piece: the rear quarter 8.
- the structure of this associated part the choice of material gives it a certain lateral flexibility both towards the internal side and towards the external side.
- An opening 15 is formed in the rear buttress, at the base thereof. This opening improves the rear flexibility of the rear quarter 8.
- a shock absorbing cushion 16 is inserted into the space formed by the three wings, it comprises a shock absorbing material of the foam type. It is designed to surround itself with a spiral around the user's lower leg. The shock absorber cushion only extends into the user's lower leg area. It is held on the outer 11 and inner 12 wings by means of two screws.
- the collar 27 is fixed, by a screw 28 on the rear side of the skate, to the rear wing or to the rear buttress. It includes a back 17, two arms 18, 19 made of the same plastic. The back 17 and the two arms are separated by more or less large notches 20 improving the lateral flexibility of the collar 27.
- a lower leg strap 21 extends the arms so that the collar tightens the upper part of the skate, against the user's lower leg.
- the position of the arms 18, 19 and of the lower leg strap define a substantially horizontal clamping plane.
- Means for vertical adjustment of the clamping plane are provided in the form of a plurality of holes formed in the rear wing and arranged in a vertical line.
- Figure 9a shows the hindquarters and the collar 27 in high position in view of a skate with maximum rigidity.
- Figure 9b shows the same pad adjusted for maximum flexibility, the collar 27 being fixed very low.
- the collar 27 can be produced by injection or by gluing and or stitching of various elements of the tissue, plastic sheet type.
- a instep holder 23 is provided to hold the user's heel at the bottom of the rear buttress. It includes an internal anchoring zone (not shown), a central force distribution zone and an external adjustment zone. The internal, central and external zones are oriented along a line called PCT for "short heel perimeter". The tightening along this line has the effect of pressing the heel of the user at the bottom of the rear buttress 9.
- the central zone is in the form of a plastron 22 while the external zone consists of a notched strap and d 'a ratchet locking mechanism 37.
- the front plate 22 has, among other things, the effect of distributing the tightening pressure of the strap and of allowing a greater tightening force without generating pain for the user.
- FIG. 11 shows a pad fitted with an alternative version of the plastron 22.
- the plastron 22 extends towards the top of the shoe and it is equipped with means for passing the lower leg strap 21.
- 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 tight against the user's foot, the connection of the strap to the buttress is relatively rigid.
- Such a plastron can be equipped with means promoting flexion, such as weakened zones. But it can also be equipped with means protecting the user from hyperflexion, such as for example one or more stops.
- the skate according to the second embodiment described here is intended to be used with any shoe, in particular a skateboard shoe or a sports shoe in general. Due to the presence of the shock cushion 16, this shoe will be low or semi-rising.
- the cooperation between the PCT instep strap and the opening 15 made in the rear buttress 4 guarantees optimal positioning of the user's lower leg. Indeed, if the user has a shoe whose sole is very wide or has significant overhangs, the sole may overflow through the opening 15 and the rear of the user's lower leg will be pressed against the wing rear 10.
- FIGS 8a, 8b and 8c show the lateral bending behavior of a skate according to the invention. Each of these figures represents a partial rear view of the skate at different times during the use of the skate.
- FIG. 8a the shoe does not undergo any lateral deformation, the collar and the clamping plane that this defined is horizontal.
- Figure 8b shows the skate subjected to lateral bending to the right.
- the inner wing is offset to the left, the collar pivots around the hinge pin 9 and causes the outer wing to flex to the left.
- Figure 8c shows a symmetrical behavior of the skate when bending to the left.
- Figures 9a and 9b show in perspective two views of the rear quarter.
- a plurality of holes are drilled arranged in a vertical line.
- the skate can be optimally adapted to the morphology of the user.
