Definitions
- the present invention relates to a skate of the roller or in-line type comprising a shoe, the sole of which is associated with an upper plate of a chassis on which the skating wheels are arranged.
- This type of brake is very effective for making an emergency stop, but can be difficult to implement by beginners due to the lifting of the wheels, and therefore the decrease in balance that it imposes.
- slowing devices consisting in having in a wheel attached to the skate and raised relative to the ground at rest, a system for absorbing energy by friction entering into action by contacting the ground by lifting the front of the skate.
- the object of the present invention is to remedy these various drawbacks by proposing a skid braking / deceleration device which is both stable and which allows relatively gentle deceleration and more particularly, but not essentially, intended for non-experienced skaters.
- the invention relates to a shoe of the in-line wheel type comprising a shoe, the sole of which is associated with an upper plate of a chassis on which the skating wheels are arranged capable of cooperating with slowing-down means work on the initiative of the skater, characterized in that said means consist of a relatively flexible friction element extending above at least one of the wheels, between an anchoring point located at the front of the latter and actuation means located towards the rear and which are capable of causing, under the effect of a pulling or pressing force on said friction element, its displacement in a radial direction relative to the wheel with which it comes into contact to ensure its deceleration, in proportion to the force applied by the skater on the means of actuation.
- the present invention also relates to the characteristics which will emerge during the description which follows, and which should be considered in isolation or according to all their possible technical combinations.
- FIG. 1 is a side view of an in-line roller skate provided with a retarding device according to the invention, shown in a rest position,
- FIG. 2 is a schematic view of the retarding device according to FIG. 1, in an active position of the retarder,
- FIG. 3 is a side view of an in-line roller skate according to FIGS. 1 and 2, but provided with actuation means of the retarding device, designed differently,
- FIG. 4 is a side view of an in-line roller skate provided with a retarding device, according to an alternative embodiment of the invention, shown in a rest position,
- FIG. 5 is a view of the retarding device according to FIG. 4, but in an active position of the retarder
- FIG. 6 is a detail view showing an effective connection of the retardation strip with a link, actuation means according to the device in FIGS. 4 and 5,
- FIG. 7 is a view showing an alternative embodiment according to FIGS. 4 to 6.
- the inline skate 1 designated as a whole and shown in Figure 1, comprises a shoe 2 consisting of an outer sole 3, intended to be made integral with the upper plate 4 of a frame 5 on which are arranged wheels, sole 3 from which extends a rod 7 covering the entire foot and extending in the direction of the skater's ankle.
- the sole 3 of the shoe 2 is made integral with the chassis 5 forming the horizontal upper plate 4 on which said sole 3 is fixed, by means of fixing means, such as screws, rivets, glue, etc..
- the chassis 5 also includes a lower part extending perpendicular to the plate 4, constituted for example by two vertical lateral wings 10 parallel to each other.
- the lateral wings 10 extend respectively at their upper part by a perpendicular return defining a plane corresponding to the horizontal plate 4
- the vertical lateral wings 10 define generally with the sole 3 of the shoe 2, an "U” reversed between the wings of which are arranged a plurality of wheels 6, for example four in number, by means of transverse articulation axes 12 integral with the chassis 4 to constitute a running gear.
- the wheels 6 are capable of cooperating with slowing means implemented on the initiative of the skater and which are constituted by a relatively flexible friction element 13 extending above at least the one of the wheels 6, between an anchor point 14 located at the front thereof and actuating means 15 located at the rear of the chassis and which are capable of being actuated by the user according to a force F, and of exerting a traction or pressure force on said friction element 13 with a view to causing it to move in a radial direction relative to a tread of the wheel 6 with which it comes into contact to slow it down, this traction or pressure force being proportional to the force F applied by the skater on the actuating means 15.
- the actuating means 15 are connected to the skater's ankle so that they can be actuated during a pivoting towards the rear of the latter.
- the slowing effect is very easily obtained by simple pivoting of the skater's ankle towards the rear, and this effect can be more or less accentuated depending on the effort exerted by the skater.
- the friction element 13 is a flexible band connected, on the one hand to the front anchoring point 14 which is fixed, and on the other hand to a point rear anchor 16 which can be fixed movably relative to the actuating means 15, said front anchor point 14 being situated lower than the upper horizontal tangent of the adjacent wheel 6 so as to bring the latter into contact with the friction strip 13 when traction is exerted on it.
- this movement of the strip takes place in the direction F1 when the pressure F is exerted on the actuating means 15.
- the friction strip 13 extends from the front anchor point 14 to the rear anchor point 16 of the actuating means 15, along a path passing under intermediate axes 17, 18, located between each pair of successive wheels , the front 14 and rear 16 axes, as well as the intermediate axes 17, 18, being lower than the upper horizontal tangent of the wheels 6, so as to apply the strip on each of the wheels included between two of said anchor points and axis intermediate, and thus to multiply the number of wheels 6 slowed down by friction of the strip 13 during the exercise of a traction thereon and consequently distribute the friction forces on said wheels and limit the wear thereof this.
- the friction strip 13 can advantageously consist of a composite braid, a leather or flexible plastic strap, etc. the flexibility of the strip is provided so that it stretches on the wheels by imparting a radial force thereon generating friction which will brake the pad.
- the advantage of this construction also lies in the fact that the deceleration effort can be distributed between the different wheels as desired by acting on the position of the axes 14, 16, 17 and 18.
- the flexibility, even a slight elasticity of the strip contributes to obtaining a progressive and soft braking which prevents the wheels from locking.
- the friction band 13 is kept out of contact with the wheels 6 by means of elastic lifting means 19, the holding force of which is determined so as to be able to be easily overcome during the implementation of the actuating means 15, and consequently of a traction of the strip 13.
- the strip 13 has substantially the same width as the wheels 6.
- the rear anchoring point 16 of the strip is constituted by a movable axis secured to the actuating means 15.
- the actuating means 15 consist of a link 21 carrying the rear anchor point 16 of the strip 13 and articulated, on the one hand on the axis 12 of the rear wheel 6, and on the other hand to a link arm 22 which is itself secured to an articulated part 7 of the shoe 2, so that a rearward tilting of the skater's leg causes, via the linkage arm 22, a tilting towards the bottom of the link 21, and consequently produces a traction F1 on the strip 13, and an application of the latter on the wheels 6, hence a slowing down by friction of said wheels 6.
- FIGS. 1 and 2 also show that the link arm 22 is connected to the link 21 by means of an articulation point 23.
- the link 21 comprises a plurality of positioning holes 24 whose distance from each of them relative to the axis 12 of angular pivoting of said link 21, relative to the wheel 6, is different, so as to be able to modify the useful length of said link 21 by moving the articulation point 23 of the connecting arm 22, or the rear anchoring point 16 of the strip.
- the traction force exerted on the strip 13 will be modified, while in the second case the braking force exerted on the last wheel 6 will be modulated.
- the front 14 and rear 16 anchor points of the strip 13 may include winding and locking means acting on the ends of said strip 13, so as to vary its length.
- the front fixed anchor point 14 and / or the intermediate axes 17, 18 under which the strip 13 passes may include means for adjusting their position in a vertical direction, so as to vary the initial tension of the strip 13.
- the embodiment of FIG. 3 differs from the previous one in that the actuating means 15A of the strip 13 are constituted by a link arm 25 connected, on the one hand, to an articulated part 7 of the shoe 2, and on the other hand, to a rear part of the chassis 5 by means of a movable axis 16A corresponding to a rear anchor point of the strip 13, and capable of moving longitudinally downward in a lumen 26 of said chassis 5 during a rearward tilting of a skater's leg, so as to cause traction on the strip, hence friction of the latter on the wheels 6.
- link arm 25 may consist of two parts capable of being screwed into one another so as to be able to vary the length thereof, and thus to vary the lever arm of the actuating means 15A.
- the link arm 2 is constituted by two telescopic tubular parts 27, 28, one of which 27 is integral with the articulated part 7 of the shoe 2 and the other 28 of the chassis 5, by means of its movable axis 16A slidably mounted in the lumen 26 of said chassis 5, a compression spring 29, calibrated according to a predetermined force, being interposed between the two parts 27, 28.
- a compression spring 29 calibrated according to a predetermined force
- the skater can independently adjust the point of action on the arm and the point of attachment of the strap.
- the friction element 13B is a flexible band connected on the one hand to the front anchoring point 30 which is fixed and on the other hand to a point d rear anchor 31 which is also fixed, said strip 13B being stretched over at least two wheels 6 substantially tangentially thereto, so that at least one higher pressure point A, B, in relation to the actuating means 15B can be exerted on the strip 13A between two successive wheels 6 in order to bring the latter, by deformation, lower than the upper horizontal tangent of the wheels.
- the actuating means 15B consist of a link 32 articulated on the chassis 5 by a front end 33 and articulated by its rear end 34 with a link arm 35, itself secured to a articulated part 7 of shoe 2, said link 32 comprising an intermediate protuberance 36 constituting the pressure point A, which is of a size such that it can act in deformation on the strip 13B until it brings it below the upper tangent of the wheels 6, during an action on the link arm 35 effected by tilting the skater's leg towards the rear.
- the link 32 comprises in its end part integral with the link arm 35 a plurality of holes 37 for positioning an articulation axis 38 of the corresponding end of this arm 35, so as to be able to modify the length of the link 32 hence the tilt angle of the skater's leg to obtain a deceleration according to a chosen force.
- the strip 13A comprises permanent connection means 39 with the pressure point A or protuberance 36 of the rod 22, so as to positively ensure that said strip 13A is put out of contact with respect to the wheels 6 in the skating phase.
- the protuberance 36 of the link 32 is connected via a hinge pin 40, to a lifting beam 41 extending on either side of the axis 40 and comprising at each of its free ends pressure points A, B, constituted by two protuberances 42, 43, so as to distribute the pressure force of the branch 13B over a greater number of wheels 6.
