Description

i 2642982 The invention relates to improvements in

  characteristics already described and claimed in the patent application No. 88 01914 filed on February 17, 1988 and having for object a roller skate as designed for a game and / or sport article allowing to roll or slide on all types of soil: tarmac, paving stones, clay, grass, wet sabze, snow, etc. The state of the art can be defined by the following patents: - USA 834,526: this patent describes a roller skate with fixing straps; this patent filed on October 30, 1906 describes the skate

1C traditional casters.

  - S 4,445,699: this patent describes a roller skate, the ground clearance and the sole of which lie below the axes of the wheels. The guard

floor is not adjustable.

  US Patent 593,278 describes a roller skate with a double braking system. Wheel wheel is for; lever brake means

operated by a strap.

  We can also cite patents

- SE 221. 4-A,

2C - USA. CS.- '.

- * AZE 25a.8'2S.

  Finally, mention should be made of French patent FR 2,290,927 which describes two-wheel skates having a chassis, a front wheel, a rear wheel and two arches for supporting the chassis on the wheels. A sole is mounted on the chassis, this sole being substantially horizontal and more broken than the trees when the shoe is in position

  of operation with its wheels in a vertical plane.

  Patent FR-2,396,569 describes pads provided with braking means comprising a lever pivotally mounted on the chassis and having at one end a brake pad capable of coming into contact with the rear wheel of the pad. A leather strap, mounted at the other end of the lever, allows the brake to be actuated by exerting traction on the strap. These latest patents describe a roller skate which has many drawbacks. In particular, this roller skate is suitable for

uniform soil.

  The fixation of the foot is of the toe type, the foot is effectively maintained leaving a flexibility of the movement, that is to say that the

  foot is maintained, while the heel remains free.

  This arrangement represents great disadvantages with regard to the

maneuverability of said pad.

  The characteristics of these skates imply that the fixed chassis is very wide, much wider than the axle that holds the wheels. This skateboard, in its technical realization, is therefore very heavy. It is difficult to adapt to different sizes. It is thus mandatory to consider manufacturing, a skate for adults and a skate for children, which increases the manufacturing cost too much. The too wide chassis and its two side members prevent the user

  to tilt the skate when cornering.

  Braking on two wheels is far too complicated and can sometimes be dangerous in certain situations. The rear wheel of said skate is not equipped with an anti-recoil device allowing the use of these skates for cross-country skiing. The guard

on the ground is not dreamable.

  In the breyets mentioned above., The front end and the rear end of the side members is integral with said chassis. There are no fork tips a-c ': ibles allowing to adjust at will the length of the

chassis and or sole.

  2nd plus, the front ends and the rear ends of said longercns are curved towards the top almost forming a right angle

  with said beams. The forks are almost vertical.

  _e pakin on wheels has a tubular frame. Said chassis has in its mrnêe structure, grooves which allow the attachment of bindings or shoes over the entire length of said chassis and this, ro-oyen zrisonniers nuts which can slide and lock in

  said grooves of the crofil of said chassis.

  Said chassis can be dismantled so that it can be cut at the user's choice and then fixed by means of attachment to the fork end caps, so that the size of the roller skate can be adapted to the size of the practitioner . According to a preferred embodiment, these grooves, two in number, are arranged on the upper face of the tubular frame at the level of each longitudinal edge. The upper face of said chassis o rests the sole of the shoe present on its entire surface with non-slip streaks. Said striations are longitudinal. The front fixing is carried out by a counter plate which, by nuts, is fixed at the desired height along the two lateral grooves of the chassis. The front strap is mounted by simple sizing, trapped between said non-slip counter plate on its face

3 2642982

  upper and the chassis itself.

  The rear binding consists of a heel which is fixed at the desired height, along the two lateral grooves of the chassis by

  two fixing screws housed in the base of the heel.

  The vertical wall which substantially forms a half cylinder to hold the heel is provided with holes for the passage of removable rivets which ensure the fixing of two lateral loops, while allowing their orientation to adapt to the profile of the kick of the user. A rear strap provided with a removable protective reinforcement is then fixed in the two loops thus making the

  captive ankle and the background of the foot secured to the chassis.

  Said attachment, according to this embodiment, may include a rear riser yes ensures comfort and maintenance of the lower part of the calf. Said extension is fixed extending the rear part of the

i5 heel piece.

  According to another embodiment, the riser is elongated, it extends to the mid-calf and is mounted articulated on the heel at the

  level of the two removable rivets.

  This elongated extension is referred to hereinafter as a universal shank attachment, because it allows the skate to be used with any city or sports shoe. This elongated riser is mounted articulated on the heel piece at the level of the two removable rivets, it can pivot forward and therefore allows the leg to bend on

1 'before.

  - a rear stop on the heel prevents pivoting backwards. The upper part of this elongated riser is provided with a pass-through strap which allows fixing above the calf and all around the leg. Like the rear strap, this strap is provided with a protective reinforcement loop 30 which prevents the straps from rubbing at the level of the tibia and the

kick.

  The chassis beam is narrower than the sole that supports it, by its length close to traditional skis and by its tubular structure it allows the screwing of ski safety bindings of

  downhill or long distance and / or hiking.

  Another characteristic of the invention resides in the fact that the support of the brake shoe consists of a steel blade which acts as a spring, so as to automatically bring the rubber shoe back, as soon as the practicing loosens the traction on the strap without the need to add any return spring

4 2642982

  additional. Said shoe support spring blade is fixed at the same time

than the rear wheel axle.

  The means of adjusting the ground clearance of the skate is constituted by the ends of the front and rear fork wheel supports which have, at their end, a female toothing which remains fitted on the male toothing

  of the heel on either side of it.

  The attached drawings are given as indicative and non-limiting examples. They represent a preferred embodiment according to

  the invention. They will allow the invention to be easily understood.

  Figure 1 is a schematic side view of the roller skate. It highlights, in dashed lines, the possibility of adjusting the ground clearance

  and the articulation of the elongated riser or universal rod attachment.

  Figure 2 is a top plan view of the roller skate

  with a section along the axis A-A shown in Figure 1.

  Figure 3 is a sectional view of the tubular chassis seen according to the

  section C-C highlighting the front fixing with its counter plate.

  Figure - is a sectional view along the axis D-D highlighting

  the teeth arranged at the end of the fork tips.

  a f-ure is urn perspective view of the tubular frame seen by 2_ one of its extré-its. In particular, it highlights the profile of said

  a.tuular frame: with its two lateral grooves.

  Figure e is a plan view of the counter plate of the front attachment. Figure - is a side view of this counter plate highlighting ^ the fixing means in the lateral grooves of the tubular frame. Figure E is a view of said counter plate seen along its longitudinal axis. The roller skate according to the invention is composed of two wheels, a 3 ^ rear wheel; and a front wheel 2. These two wheels are integral by their axis with a chassis 3 receiving a sole which allows, by means of fixing to the user, to fix his shoes. Said shoe comprising at least on its rear part a brake actuated by a cable and a lever. Said lever can be actuated by a strap. All these elements are known in particular from the patent which was the subject of an application

main patent.

  The tubular frame 3 can be made of light alloy or composite material. The width of said frame 3 is less than the sole intended to receive the binding for the shoe. Said tubular frame m 3 is removable. The wheels being fixed by their axis on end caps

removable fork 4, 5.

  Said fork ends are fixed to the chassis beam by fixing means, adjustment means make it possible to adjust the clearance at

  ground. All of these are known.

  One of the characteristics of the invention resides in the tubular chassis 3. Said tubular chassis 3 is removable so that it can be cut at the user's choice and then fixed by fixing means on the fork ends 4, 5 wheel supports 1, 2 and this, so as to be able to adapt the size of the roller skate to the size of the practitioner. The user can reduce the length of said chassis 3 indifferently by cutting a part on the front or on the rear because the tubular chassis 3 has in its structure grooves 6, 7 which allow the fixing of bindings or shoes over the entire length of said chassis 3 and this, by means of "captive" nuts which can slide and lock in said grooves 6, 7 of the profile of the tubular chassis 3. These grooves 6, 7, two in number, are arranged on the upper face tubular frame 3 at each edge

1 longitudinal.

  The upper face 8 of said tubular frame 3 o rests the 2D sole of the shoe, has non-slip ridges over its entire surface

  9. Said striations are longitudinal.

  The front fixing is carried out by a counter plate 9 which by ir nuts, I1 is fixed at the desired height along the two lateral grooves 6, 7 of the chassis 3. The front strap 12 is mounted by simple screwing. It is trapped between said counter-plate 9 on its

  upper side and the chassis itself.

  This blocking prevents lateral slipping of the strap.

  The foot is fixed at the front and at the heel, from

  very tight to make the roller skate integral with the foot.

  There is no flexibility in the heel. Stability is ensured by the use of shoes. The user is offered an optional screwing kit allowing the shoe to be screwed directly to the chassis with two counter plates and four screws. Stability is ensured by the use of sports or hiking boots that maintain the ankle while allowing all changes. This using:

  - either the shoe screwing kit on the chassis 3.

  - Either the standard type binding supplied with the roller skate, ie the front strap 12 as defined above and the rear binding 13 which consists of a heel piece 14 which is fixed at the desired height. along two lateral grooves 6, 7 of the chassis 3 by

6 2642982

  two fixing screws housed in the base of the heel piece 14. The two fixing screws are screws 15 and 15. The vertical wall 17 which substantially forms a de-i-cylinder for holding the heel is provided with holes for the passage of removable rivets 18 and 19. These removable rivets 18 and 19 ensure the attachment of two side loops while allowing their orientation to adapt to the profile of the kick of the user. A rear strap 20 provided with a removable protective reinforcement 21 is then fixed in the two loops thus making the

  captive ankle and the background of the foot secured to the chassis 3.

  This attachment may include a rear riser not shown on the

  figures which ensure comfort and support of the lower part of the calf.

  This shoe is fixed extending the rear part of the heel.

  Of course, there can be at least two sizes of extension which are

  offered either for an adult or for a child.

  1_5 According to the embodiment shown in FIG. 1, the extension is an elongated renausse. This elongated riser 22 extends to mid-ncllet and is shown articulated on the heel piece 14 at the level of the two removable rivets -E, 9. This elongated riser 22 is hereinafter referred to as "universal rod attachment" because it allows the use of the 2C roller skate with any city or sports shoe, even if these boots provide no support at the ankle. This attachment with its articulated extension thanks to its design allows the use of said pad with low shoes or even

barefoot.

  2_ This elongated riser 22 is articulated on the heel piece 14 at the level of two removable rivets. The two loops of the back strap

2_ remain indenticates.

  This elongated riser 22 can pivot forward and therefore allows the leg to bend forward. A rear stop on the heel piece 14

  3S prevents the pivot-oterrent backwards.

  The upper part of this elongated riser 22 is provided with pass-through straps 23 which allows the attachment above the calf and all around the leg. This strap is provided, like the rear strap, with a protective reinforcement loop 24. The protective reinforcement loop 24 prevents

  rubbing straps at the level of the tibia and the foot cup.

  This elongated riser 22 is more flexible at the calf and provided in its internal part with protective reinforcements as there are in ski boots and this, so as to isolate the leg from the rigid plastic shell and thus avoid any injuries. by increasing the

  A braking device is integrated. It consists of a semi-rigid strap that can be pulled by the practitioner and allows to actuate a multiplier lever 25 whose pivot axis 26 is fixed on the outside of the tubular frame 3 and which allows access by via a bicycle brake cable 27 (which slides inside the tubular frame 3). The rubber brake shoe 28 has been molded so that the curve of its outer surface exactly corresponds to the inner curve of the rim 29 of light alloy or composite on

  which he will wear to cause the braking.

  All of these provisions are known. The characteristic of the present invention resides in the fact that the support 30 of said pad 28 is itself a spring steel blade 30 which automatically brings the rubber pad 28 back as soon as the practitioner releases the traction on the strap and this, without that there is no need to add any

additional return spring.

  Said support blade 3_ of the brake shoe 28 is fixed at the same time as the axis of the rear wheel 3- which makes it possible to change the position of the wheel axis 31 to change for example the ground clearance of the tubular chassis 3 depending on the type of terrain where we are evolving and this, while 2C maintaining the optimal position of said pad 28 relative to the rim 29

of the wheel.

  The semi-rigid brake control strap is equipped with a system

  of adjustment, of the strap type to adapt to the size of the user.

  Another clip, of the strap type, allows its attachment to the belt or to the user's pocket. These means are not shown in the drawings. The fork ends 4 and 5 front and rear, wheel supports 1 and 2 have at their end a female toothing which comes to fit

  on the male toothing of the heel on either side of it.

  By unscrewing, we slightly spread the forks 4, 5 we choose its ground clearance, and by screwing it back in we lock the male teeth in the female teeth. Stabilization is thus obtained after rapid adjustment, said adjustment being progressive since degree by degree without disassembly of the wheel, which was not the case in the various pads.

known to date.

  The entire foot fixing device consists of a plastic front strap in one part equipped with an automatic locking loop allowing immediate tightening of the foot even while riding, thanks to the notched profile of said strap. At the back, a complete set of metal and / or rigid plastic heel pieces to which two

S 2642982

  automatic locking loops on either side of the foot in which are fixed a notched strap at its two ends and widened on the part resting on the kick to not be hurtful. he fastening device allows quick locking and tightening of the front and rear straps requires the use of hands. The size of the straps and their shape allow the tightening of the high shoes

  which by maintaining the ankle, contributes to the stability of use.
