Definitions
- the invention relates to a roller skate, in particular an inline wheel.
- roller skates are either autonomous, that is to say independent of the shoe, or integrated, that is to say forming a single piece with the shoe.
- the invention aims to improve skates of the first category, that is to say autonomous skates.
- the invention overcomes these drawbacks.
- the skate according to the invention is characterized in that it comprises a plate provided with means of attachment, preferably of the quick type, to a shoe, a running gear comprising a chassis and wheels fixed to this chassis, and means for detachably fix the running gear to the plate.
- the removable base and undercarriage give the skate a modular character.
- This modularity brings many advantages.
- the skater may have a single plate and a plurality of running gear, two running gear differing either in the number of wheels or in the diameter of the latter.
- the plate and the running gear are configured in such a way that the running gear can be fixed indifferently in one direction or the other. In this way the skater can turn the running gear in particular to compensate for asymmetrical wear of the wheels.
- the chassis is for example constituted by a simple profile having two longitudinal walls receiving the axes of the wheels.
- the plate preferably comprises, in its lower part, at least two tabs located on the longitudinal sides of the plate.
- the removable fixing means are provided for attaching the legs of the plate to the longitudinal walls of the chassis.
- connection of the plate to the chassis is, in one embodiment, carried out in such a way that the flexibility of the plate ensures damping between the shoe and the running gear. It is also possible to provide damping means, such as “silent-block” type bodies, between the plate and the running gear.
- the plate can be fixed in variable positions relative to the running gear.
- the plane of the plate is parallel to the plane containing the axes of the wheels and, in another position, the plane of the plate is inclined relative to the plane containing the axes of the wheels. This inclination is for example directed downwards from the rear or is directed downwards from the outside.
- the plate is connected so as to be able to pivot, at a limited angle, relative to the chassis.
- braking means comprising a braking element controlled so that it comes into action, against the ground or against a wheel, when the skater exerts a tending action. to tilt the plate relative to the chassis.
- This brake control is particularly simple and ergonomic. It can be done under the effect of the skater's weight.
- the braking control means is preferably such that in normal operation, without braking control, the plate has a fixed position (not pivoting) relative to the chassis and the tilting controlling the braking is effected by an effort of the skater, who uses his weight.
- this control means there is provided, between the chassis and the plate, a leg formed by two rods, one of which is articulated to the plate and the other to the chassis; these links are hinged together, and the leg can only bend in one direction. Without control or braking force the leg remains straight.
- the brake control allows you to bend your leg. The latter returns to its upright position in the absence of braking force; preferably a spring is provided to assist in returning to the extended position of the leg.
- the braking element is either fixed to the plate or is pivotally connected to the chassis. In this way, the wheels can stay in contact with the ground when braking.
- a command for tilting the plate in the opposite direction to the tilt controlling the braking authorizes a metering of this braking.
- FIG. 1 is a diagram showing a shoe and, the disassembled state, a skate according to the invention
- FIG. 2 is a diagram of a plate fixed to a chassis in a first position
- FIG. 3 is a diagram similar to that of FIG. 2, but for a fixing of the plate to the chassis in another position
- FIG. 4 is a diagram similar to that of FIG. 2, but for a variant
- FIG. 5 shows a part of the shoe represented in FIG. 4
- FIG. 6 is a section along the line 6-6 of FIG. 5
- FIG. 7 is a diagram of a shoe comprising braking means
- FIG. 8 is a diagram similar to that of FIG.
- FIG. 9 is also a diagram of a skate part showing a varian te of realization of the braking means.
- FIG. 1 in which a shoe 22 and a shoe 20 formed of a plate 24 and a running gear 26 have been shown.
- the sole 23 of the shoe includes catching receiving elements (not shown) cooperating with catching means (also not shown) located on the plate 24.
- the running gear 26 has four wheels 28l to 284 mounted on a chassis 30 consisting of two vertical flanges 32 (only one of which is visible in FIG. 1) connected at their ends by webs 34 and 34 'and receiving the axes 36i to 364 wheels.
- the aligned openings 38 ⁇ are between the wheels 28 ⁇ and 282 while the aligned openings 382 are between the wheels 283 and 284.
- Cross sails 34 ⁇ and 342 frame the openings 38l in order to reinforce the structure.
- transverse webs 343 and 344 frame the openings 382.
- a web 345 also intended to reinforce the structure, is provided in the central part, between the wheels 282 and 283.
- the running gear is symmetrical with respect to a median plane 40, perpendicular to the longitudinal axis of the shoe. It is therefore reversible, that is to say that the wheel 28i can be either the front wheel or the rear wheel.
- the openings 38 ⁇ and 382 are intended to cooperate with corresponding openings provided in lugs 42 and 422 of the plate 24.
- the plate 24 has, in plan, a shape (not shown) corresponding substantially to the sole of the shoe.
- the legs 42 ⁇ are located forward. They project from the underside 241 of the plate, at its lateral edges.
- the spacing between the front legs 42 ⁇ (only one of which is visible in the figure) is such that the inner face of each leg 42 ⁇ is applied against the outer face of each flange 32.
- each leg 42 ⁇ has a trapezoidal shape, the smallest side of which is that which is distant from the plate 24.
- Each leg 42 ⁇ has three openings 44, 442 and 443. The centers of the openings 44i, 442 and 443 are aligned vertically , that is to say perpendicular to the plane of the plate 24.
- the legs 422 have openings 444, 45 and 446, the centers of which are aligned vertically.
- the plate 24 it is possible to arrange the plate 24 so that the rear part, the heel part, is raised relative to the front part. It is also possible to tilt the plate 24 around a longitudinal axis, the outer longitudinal edge being for example raised relative to the inner longitudinal edge.
- a braking element 46 for example of a plastic material. To brake the skater tilts his foot backwards so that the braking element 46 touches the ground.
- the axes 36i to 364 of the wheels are substantially in the middle, in the direction of the height, of the walls 32. Thus the wheels protrude from the chassis up and down.
- FIG. 2 differs from the embodiment represented in FIG. 1 by the relative position of the axes of the wheels 28l with respect to the longitudinal walls 32 of the chassis 26, as well as by the openings provided in the tabs 42 'and in the walls 32.
- the axes 36l of the wheels 28l are not disposed midway between the upper 31 and lower edges 33 of the walls 32, but are closer to the lower wall 33 than to the upper wall 31.
- the wheels 28i are projecting , down, from edge 33, but do not extend upwards above edge 31.
- Each tab 42 '1, 42'2 has a single opening, respectively 50 ⁇ and 502-
- Against by the walls 32 have three pairs of aligned openings, respectively 48i, 482 and 483 between the wheels 281 and 282, as well as three other pairs of aligned openings, respectively 484, 485 and 486 between the wheels 283 and 284.
- the multiplicity of openings 48i plays the same role as the multiplicity of openings 44i of the skate of FIG. 1.
- the plate 24 is arranged in such a way that the rear end 25 is raised relative to the front end 23.
- the removable fixing of the plate to the running gear is effected for example using screws (not shown) passing through the openings 38l and 44 ⁇ or 48i and 50 ⁇ cooperating with nuts also not shown.
- the flexibility of the plate 24 and the legs 42 makes it possible to attenuate, to a certain extent, the transmission, towards the foot of the skater, of the shocks undergone by the wheels 28i.
- the plate 24 comprises, for its attachment to the chassis 26, a single pair of lugs 51 in the central position having one or more openings 52 intended to cooperate with one or more corresponding openings on the side walls 32 of the chassis 26. These wall openings 32 are located between the wheels 282 and 283.
- Damping blocks 54 ⁇ and 542 are arranged, respectively at the front and at the rear, between the plate and a ceiling 27 of the chassis 26. These damping blocks, of the "silent-block" type, are fixed either on the underside of the plate 24, either on the ceiling 27 of the plate, or both on the ceiling and on the plate.
- the fixing of these blocks 54 ⁇ and 542 is such that it allows their displacement in the longitudinal direction so as to be able to choose, at will, the position of these elements.
- a second position of the damping elements there is shown in broken lines, a second position of the damping elements.
- damping effect is obtained not only by the blocks 54 ⁇ and 542, but also by the flexibility of the plate on either side of the legs 51.
- This flexibility also depends on the front 55 and rear 57 locations of the fastening means (not shown in detail) of the plate to the sole of the shoe.
- the front "silent-block" 64 can be arranged in two separate locations, one near the front end of the plate 24, and the other between the wheels 28i and 282- Of course, similar provisions are found at the rear of the skate.
- the plate comprises, at the front, an opening 60 formed by stamping so that this opening is bordered in the upper part, by a cell and, in the lower part, by a projection 61.
- the side walls 32 of the chassis 26 have, in their upper part, at the front, openings 62 with the same longitudinal positions as the opening 60.
- the plate 24 has an opening 58 formed by a stamping directed downwards. In the example shown in FIGS. 5 and 6, it is this opening 58 which is used to fix the "silent-block" 64.
- the opening 58 and the block 64 pass through a threaded rod 66 with which a nut 72 cooperates, housed in the cavity formed in the upper part of the plate 24 by the stamp surrounding the opening 58.
- the threaded rod 66 ends, at its lower part, by an enlarged part 68 having an oblong opening 69 (FIG. 5) elongated in the vertical direction.
- This oblong light passes a rod 70 fixed to the walls 32 ⁇ and 322 of the frame 26.
- This rod 70 therefore crosses openings 62 and 622 of the walls 32 and 322- It is held at these walls by means of removable fixing means (not shown ).
- the underside of the silent-block 64 is moreover fixed to a plate 67 resting on the upper edges of the walls 32 and 322. This plate 67 is of course crossed by the rod 66.
- the braking element 84 is fixed to the rear end of the plate 24.
- the rear is provided wheel 284 one leg
- the rod 77 is projecting above the plate 24. It has a return 86 directed towards the front which is intended to cooperate with a lever 88 articulated, along axes 90, to tabs 91 projecting upwards. edges of the plate 24.
- the legs 91 are in front of the axis 80.
- a spring 92 is integral with the lever 88 and the plate 24 in such a way that it always brings the lever 88 upwards.
- the articulation of the links 76 and 77 is such that they can only be folded in one direction. More precisely: in the position shown in Figure 7 the links 76 and 77 are aligned and therefore form a vertical leg. The leg can be bent only so that the axis 78 moves backwards and not forward.
- the braking can be adjusted by the skater with a slight pressure exerted towards the front, which releases the braking, possibly gradually.
- the skater exerts strong pressure forward.
- the embodiment of the invention which is shown in Figure 8 differs from that shown in Figure 7 by the position of the leg 751 which is between the wheels 283 and 284.
- this leg 751 can not be folded in the opposite direction of the leg 75 of Figure 7, that is to say that the axis 78 common to the rods 76 and 77 ⁇ can move only forward (and not backward) to from the rectilinear position of the leg shown in Figure 8.
- the rear part of the plate has an opening 89 through which extends an arm 93 extending the lever 88.
- the end 98 of the arm 93 cooperates with a rod 97 located along the axis 78.
- the operation of the skate shown in FIG. 8 is similar to that described in relation to FIG. 7. The only difference is that to control the braking the arm 93 presses on the rod 97 which thus pushes the articulation 78l forward, which allows to apply the braking element 84 against the ground.
- the braking element 84 is not integral with the plate 24 but with the frame 26 to which it is articulated.
- the articulation 822 is common with the articulation, at the rear of the chassis 26, of the link 762 of the leg 752-
- the braking element 84 ⁇ also comprises an upper arm 94, the end 99 of which is intended to cooperate with the rod 772-
- the leg 752 is foldable in a direction such that the articulation 782 can only move forward from the straight leg position shown in Figure 9.
- the upper edge of the arm 94 has a lug 96 forming a stop intended to cooperate with a projection 100 at the rear lower end of the plate 24.
- the leg 752 In normal operation, in the absence of a brake control, the leg 752 remains straight and the brake block 102 of the element 841 is removed from the ground 104.
- the skater wants to brake, he shifts his weight backwards slightly lifting the front part of the shoe, which has the effect of applying the brake block 102 against the ground 104 and, thus, causing the element 84 to tilt forwards.
- the link 772 is then pushed forward by the arm 94, which folds the leg. In this position, the projection 100 of the plate 24 can cooperate with the lug 96 to push the block 102 against the ground, the wheels all having returned to their normal rolling position on the ground.
- the braking can be measured by pressing more or less on the rear part of the plate 24.
