Definitions
- the invention relates to an inline roller skate, that is to say with all the wheels arranged lengthwise on a line, provided with a braking device actuable by a movement of the collar of the shoe of the skate or by the skater leg.
- a braking device Since braking of a roller skate cannot in principle be done in the same way as braking on the side of an ice skate at the risk of damaging the bearings of said wheels, a braking device has been preferably added.
- the user of the skates must operate braking by tight and supported turns which is similar to slowing down making the braking distance long enough, or braking in T with the rubber of the wheels leaving one of the pads to drag behind in the transverse position relative to the running line.
- T-braking does not require any particular mechanism, but it can only be used at relatively slow speeds and also quickly wears the wheels while having a long braking distance.
- the braking device is usually placed on one of the two pads to be able to brake for example by placing one leg in front of the other, that is to say in scissors.
- the device acts directly on the wheels or on the ground.
- An example of a commonly used braking device consists in placing an elastomer pad on the front or on the back of the pad in order to come into contact with the ground to brake.
- the mounting of these studs has become widespread, since they are inexpensive.
- braking by pressing on the ground with an elastomer pad is not very comfortable and the braking distance to stop is relatively long.
- Other embodiments of braking devices which have done the work for the most part of patent protection, have been proposed without however being perfectly suited to the practice of roller skating.
- One of the embodiments consists of a braking device for all the wheels of the two skates which includes discs integral with the chassis placed on the outer sides between the wheels and the chassis.
- a braking device for all the wheels of the two skates which includes discs integral with the chassis placed on the outer sides between the wheels and the chassis.
- US Patent 5,41 1, 276 describes, for example, an embodiment in which the user operates the braking on a lateral surface of the two rear wheels of one of the pads in line with a brake actuated by a manually operated control lever and connected by cable to the skid brake linkage.
- a drawback of such an embodiment essentially lies in the fact that the skater must constantly hold the control handle in hand in order to be able to control the braking of the skates which only takes place on the running surface of the rear wheels.
- WO 98/40133 describes such a braking device in which a rod comprises openings housing the wheels and is placed on the axis of said wheels. The rod is pushed forward against return means by a lever articulated on the rear of the shoe so that the edges of the openings come into direct contact with the rolling surface of the wheels.
- a major drawback of having to brake by direct contact with the wheel is that significant heating tends to quickly destroy the wheels which are in themselves already sufficiently subject to wear by their contact with the ground.
- embodiments have concerned the addition of discs of a material, in particular metallic, on a lateral surface of the wheels and of brake pads carried by an element connected to the chassis. brought in the direction of the discs for braking.
- a disc brake device for an in-line roller skate is described in US 5,657,999. It includes two discs mounted on each side of the two central wheels, two rods rotatably mounted on the chassis along an axis of rotation perpendicular to the axes of the wheels carrying brake pads, a rod control lever rotatably mounted under the shoe according to a axis of rotation parallel to the axes of the wheels, a pedal housed inside the shoe to be able to actuate the lever and the rods against return means to bring the pads into contact with the discs for braking.
- the braking device consists of the control lever connected on one side to the shoe collar and on the other to a rotary brake pad mounted on the axis of rotation of the rear wheel, a brake rod connects this first pad to other rotary brake pads mounted on the axis of rotation of other wheels, a surface of said pads opposite the contact surface with the wheel comprising ramps cooperating with projecting elements on inside the chassis so that by acting on the control lever the plates by turning are brought against return springs in the direction of a lateral surface of each of the wheels provided with plates to brake them.
- two braking rods placed on each side and along the length of the row of wheels at their axis of rotation include longitudinal slots so that they can slide on the axes of rotation and a certain number of ramps as brake pads placed opposite each wheel so that by acting on the control lever, the rod slides against biasing means forward bringing the ramps into contact with a lateral surface of each wheel.
- a disadvantage of such a device consists in that the braking force is applied directly at the axes of rotation of said wheels or on the periphery of said wheels which generates too brutal braking and too quickly wears the wheels or even the brake pads. . This therefore does not make it possible to differentiate the pressure on the discs as a function of the position of the wheels on the pad.
- An object which the object of the invention proposes to solve consists in overcoming the drawbacks of the braking devices mentioned above by means of an in-line roller skate provided with a braking device with soft and progressive action.
- an inline roller skate comprising at least three wheels mounted on a chassis on which is fixed a shoe and a braking device which comprises a control lever articulated on the chassis of the skate, a side rod carrying brake pads guided lengthwise on the chassis and return means for bringing the rod into a rest position, a backward movement of the shoe or of the leg of a user to drive the lever that pushes the rod longitudinally against biasing means in a braking position of the wheels, the shoe being characterized in that at least one ramp is provided on the guide path of the rod so that, during a braking command, the rod moves against biasing means forward and in the direction of discs mounted on a lateral surface of the wheels to bring the brake pads into contact with the discs, said ramp being mounted on the rod or on at least one member of guiding the chassis between two adjacent wheel axles so that the braking force imposed on the brake pads against the discs is applied at a point on the rod at the level of the ramp, while allowing the rod to
- An advantage of the braking device consists in using the rotation of the wheels to drive, by friction towards the front, against return means, the rod carrying the brake pads as soon as said pads come into contact with each disc of the wheels, and thus gradually and more strongly apply the pads against the discs to ensure self-braking thanks to the displacement imposed by the ramps on said rods.
- Another advantage of the braking device consists in applying the braking force to the pads at points on the rod located between the axes of two neighboring wheels, and by playing on the elasticity of the metal rod to ensure soft and progressive braking. .
- the skate has four wheels, it is necessary to have at least two ramps on the rod located between the axes of two neighboring wheels. The first ramp is therefore between the two rear wheels and the second ramp is between the two front wheels.
- two rod ramps are used for the three rear wheels, while a third ramp is used between the two front wheels.
- the ramps can be placed in such a way as to obtain differentiated braking (differential braking).
- the ramp located between two neighboring wheels can be offset, which means that the braking force of the pad closest to the ramp is greater than the braking force of the pad furthest from said ramp.
- the braking is done on discs, for example of steel, placed on at least one side of the wheels by means of brake pads generally made of graphite. An insulation joint is interposed between this metal disc and the surface of the wheel in order to prevent heating of the discs during braking being communicated to the rubber of the wheels.
- braking by the wheels is difficult to achieve because it is necessary to measure the braking power on said wheels as a function of the possible grip of the wheels on the ground. This grip is a function of several factors, such as the quality of the "Gripp" of the tire, the diameter of the wheel, the number of wheels braked, the characteristics of the ground and the braking device made up of the materials of the discs and platelets, and the pressurization mechanism which must be progressive.

- - Figure 11 shows a partial longitudinal section along AA at the frame of the skate of Figure 10
- FIG. 12 shows a partial section along B-B at one of the wheels of the skate of Figure 1 1.
- FIG 1 shows a first embodiment of an inline roller skate.
- the skate includes four wheels.
- Said skate may include three, four, five or more wheels in the case of a roller skate used in downhill competitions for better stability.
- the roller skate comprises a shoe fixed above a metal chassis 22 under which the wheels 11 of the skate are arranged between two walls of said chassis 22 and kept distant from the walls by two separating elements 21, visible in FIGS. 4 to 6.
- the wheels 11, made for example of polyurethane, are fixed to the walls of the chassis 22 by an axis passing through the ring or the inner cage of a ball bearing.
- the axle is held fixed to the chassis by a screw-nut arrangement 20. The same is true for the inner ring of the bearings ball or the inner cage keeping them in the wheel thanks to the separating elements.
- a control lever 1 is rotatably mounted along an axis of rotation 19 on a rear part of the chassis 22.
- the upper part of the lever 1 is connected in rotation 15 to the collar of the shoe, while its lower part 2 is used to push a lateral rod 3 guided longitudinally on one of the walls of the chassis 22 and held in the rest position (without braking) against a stop of the chassis by return means.
- An adjustment screw 4 near the axis of rotation 19 of the lever makes it possible to angularly adjust the position of the lever on the chassis in order to be able to act on the inclination which must be given to the collar or even to the leg in order to be able to brake more. sooner or later.
- the rod 3 which can be in one piece or in two half-parts 3a and 3b as shown in FIG. 1 of the first embodiment of the shoe, is made of a metallic material, preferably an alloy of aluminum, to be able to guarantee a certain elasticity during braking.
- Brake pads 5 made for example of graphite are mounted on the rod in a number equal to the number of metal discs 6, preferably of steel, mounted on a lateral surface of the wheels 11.
- the brake pads 5 are four, just like the number of discs 6 so as to be able to brake all the wheels 11 of the shoe in order to ensure uniform braking on said wheels 11.
- Each part or blade 3a or 3b of the rod comprises on the side facing the guide wall of the frame 22 a ramp 7a or 7b which cooperates with a corresponding ramp made in a housing of the guide members 13a and 13b of the frame 22.
- the ramp 7a or 7b comes to bear against a rear stop of each housing of the guide members. Since the housing can be shaped to have the complementary shape of the ramp 7a or 7b of the rod, the rod is in abutment when its ramp fully occupies the housing of the member 13a or 13b. In this rest position, the face of the rod facing the wall comes to bear against said wall of the chassis.
- the shape of the housing of the guide members 13 and 13b is in no way limited to the complementary shape of the ramps 7a and 7b, and those skilled in the art can imagine various other shapes capable of ensuring the guidance of the ramps without departing from the scope of the invention.
- the housing of each guide member may also include the ramp, while the rod only comprises projecting elements each coming into contact with the corresponding ramp for guiding said members provided that the function of bringing the brake pads 5 in the direction of the discs is performed during the advance of the rod.
- the rod 3 carrying the brake pads 5 and guided by the members 13a and 13b is placed above the axes of all the wheels so that in the braking position each brake pad 5 comes to support an upper surface of the disc 6 of each wheel 11.
- the rod 3 is pushed forward and by means of the ramps 7a and 7b brings the brake pads in the direction of the wheel discs.
- the rotation of the discs tends to pull forward independently of the lever said rod and in fact forces the pads 5 to come to bear more strongly against said discs 6 so as to guarantee self-braking while keeping the application of the braking force on the pads by the ramps between two neighboring wheels.
- the two half-parts 3a and 3b of the rod are connected by a spacer 8 housed in a guide element 38 and movable longitudinally.
- Each end 9 of the half-parts 3a and 3b also consists of a ramp bearing against corresponding ramps of the spacer 8 in order to impose a force on the ends of the half-parts 3a and 3b in the direction of the wheel discs when of the rod advance during a braking operation.
- the braking mechanism or device comprises a rod separated into two half-parts 3a and 3b with a ramp 7a and 7b each, a spacer 8 between the two half-parts of the rod allowing their connection when pushed forward causing braking by pressurizing the pads 5 against the discs 6.
- ramps 7a and 7b and the ends 9 of the half-parts of the rod 3a and 3b also shaped as a ramp to rest on complementary ramps of the spacer 8 which cause the platelets to pressurize against the discs.
- Two return springs 10a and 10b, guided in tubular parts 28a and 28b fixed on a wall of the chassis 22 facing the wall guiding the rod 3a and 3b each push with the aid of a wedge 30a and 30b resting on other ramps 7'a and 7'b opposite to ramps 7a and 7b for pressurizing the plates, the rod in the rest position against a stop of the chassis 22, in particular against a rear part of the housing of the guide members 13a and 13b.
- Figure 3 shows an example of application of the braking device on both sides of the wheels.
- the operation of the rod 3 for braking is identical to that previously described with the only difference that one brakes on both sides of the wheels 11.
- the return springs 10a and 10b are each housed in a tubular part which does not bear on one of the walls of the chassis 22 opposite the pressure ramps of the plates, but is connected above said ramps to one or both walls by a mechanical connection, not visible in figure 3.
- FIG. 4 shows the mounting of the discs 6 on a ball bearing cage 12 in which the ball bearings are mounted 14.
- the part of the cage 12 supporting the disc 6 overflows more important than on the other side of the wheel 11.
- An anti-friction and thermal seal 18 is disposed between the disc 6 and the wheel 11 to avoid overheating of the rubber of the wheel 1 1 during the braking friction of the pad 5 against the metal disc 6.
- the wheel 11 with its ball bearings 14 is placed between two walls of the chassis 22.
- the inner part of the bearing 14 is held in position between the walls by two elements 21 one of these elements of which is larger in order to offset the wheel by function of the rod 3 guided on one of the walls of the chassis 22.
- a metal axis defining the axis of rotation of the wheel 1 1 with a screw-nut arrangement 20 passes through the wheel 11 and the elements 21 to hold them.
- Figure 5 is a variant which shows the disc 6 mounted directly on one of the ball bearings 14. While in Figure 6 showing another variant, the disc 6 is mounted on a bearing cage 12 passing right through the wheel 11.
- Figure 7 shows a second embodiment of the roller skate in line with its braking device.
- the essential difference compared to the first embodiment and its variant lies in the fact that the control lever 1 is no longer directly connected to the collar of the shoe, but resting against a cam 16 which defines an inclined plane .
- the control lever 1 When the upper part of the shoe pivots backwards, it drives the lever in rotation around its point of rotation 19 in order to be able to impose a forward movement on the rod 3 against the return means constituted mainly by the springs 10a and 10b each pressing a corner 30a and 30b against a ramp 7a and 7b visible in Figure 2 so that the brake pads 5 come into friction against the discs 6 of the wheels 11.
- braking is obtained by advancing the leg with the pad provided with the braking device so that the legs are in the scissor position.
- This causes the control lever 1 to pivot backwards which, by pivoting on the axis 19, causes the lower part 2 of said lever to be pressed forward.
- the two half-rods 3a and 3b move forward and towards the discs 6 of the wheels by means of their ramps 7a and 7b, visible in FIG. 2, pressing against corresponding ramps of the members guide 13a and 13b of the wall of the frame 22 guiding the rod.
- the brake pads 5 thus come into contact with the discs 6 integral with the wheels 11 in advance of the rod 3.
- the longitudinal positioning and between the axes of two adjacent wheels of the ramps ensures a differentiation of the braking pressure on each of the wheels, which guarantees a certain flexibility in the application of the braking pressure according to one of the goals desired solve the object of the invention.
- Figures 8 and 9 show more explicitly the principle of braking with the application between two wheel axles 11 adjacent to the bearing force of the brake pads 5 against the discs 6 of the wheels.
- the ramp 7 along the ramp of a frame guide member 22 brings the brake pads 5 into contact with the discs 6 while slightly bending the rod 3 in application of the force at the point of support of the ramp on the guide member.
- the curve f in FIG. 8 shows somewhat exaggerated the deflection of the rod at the point p of application of the braking force.
- the rotation of said wheel further drives the rod forwards which ensures self-braking independently of the control on the control lever.
- Figures 10 to 12 show a third embodiment of the roller skate in line with a braking device similar to that explained above. All elements identical to those shown in Figures 1 to 7 bear the same reference signs. The description of this third embodiment only explains the main differences of a roller skate provided with a braking device which includes five wheels for use essentially for downhill sports competitions for example in order to have better stability.
- a plate 32 is added and screwed by screws 33 to one of the walls of the chassis 22 in order to be able to guide, using a longitudinal groove, a rod 3 carrying the brake pads 5.
- the rod in this third embodiment is therefore on the outside of one of the walls of the chassis 22 between which the wheels 11 are placed so as to be able to facilitate the change of the worn brake pads by only removing the plate 32 without having to remove the wheels during this change. It should be noted that the brake pads are much more worn in a downhill competition, which is why they must be changed easily.
- slots 36 are machined on the wall of the frame 22 on the plate side 32 allowing protrusions 37 of the rod to pass through.
- the width of the lights must be such that it allows the rod to be able to slide lengthwise between at least one rest position and one braking position.
- a return spring 35 of the rod to the rest position without braking is placed in a housing 39 formed over a length of the rod 3 and bears against a stop 34 of the plate fixed to the chassis 22.
- the return force of the rod is directed in this third embodiment longitudinally.
- the springs 10 housed in the tubular parts 28a to 28c only serve to push the rod into the guide groove of the plate 32.
- the shoe comprises five wheels, three ramps for applying the force uniformly on all the wheels are provided.
- the first two ramps 7a and 7c are intended for the three rear wheels, while the third ramp 7b is intended for the two front wheels.
- Said ramps 7a to 7c are supported in housings comprising complementary ramps formed along the guide grooves of the plate.
