Definitions

  • the present invention relates to two-wheel skates provided with braking means.
  • French patent 2,290,927 describes two-wheel skates having a chassis, a front wheel and a rear wheel, and two shafts for supporting the chassis on the wheels.
  • a sole is mounted on the chassis, this sole being substantially horizontal and lower than the shafts when the shoe is in the operating position with its wheels in a vertical plane.
  • 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 skate.
  • a leather strap mounted at the other end of the lever allows the brake to be actuated by exerting traction on the strap.
  • One of the aims of the present invention is to provide a two-wheeled skate with greater braking efficiency.
  • Another object of the invention is to provide such a two-wheeled skate having powerful braking means while avoiding any lateral offset when these means are used at very high speed.
  • the invention provides a two-wheeled skate having a chassis, a front wheel and a rear wheel, two shafts for supporting said chassis on said wheels, a sole mounted. on said chassis, said sole being substantially horizontal and lower than said shafts when the shoe is in the operating position with its wheels in a vertical plane, and braking means, characterized in that said means comprise two levers pivotally mounted on said chassis, each lever having at one of its ends a brake shoe capable of coming into contact with one of said wheels, common brake actuation means for actuating the two brake levers to bring said shoes into contact with said wheels , and connecting means for connecting said levers to said brake actuation means.
  • each wheel of the skate is provided with a brake, the braking efficiency is improved. But it has been found that, surprisingly, although the front wheel has a brake, there is no lateral offset because there is only one brake actuation means for the two levers of brake.
  • the pad according to the invention comprises a tire and a rim having a cylindrical surface coaxial with the axis of said wheel, each lever being mounted pivoting about an axis parallel to said shafts, each brake pad being mounted on said first end of its respective lever so that it faces said cylindrical surface, said brake actuating means and said levers being connected to said connecting means so that each lever pivots about its axis respective in response to an upward pull on said brake actuating means so as to bring each brake shoe into contact with the cylindrical surface of the rim of its respective wheel.
  • said levers are substantially aligned
  • said connecting means comprising a connecting rod substantially aligned with said levers, and connected at each of its ends with the second end of one of said levers, said brake actuation means being fixed to said connecting rod to pivot the two levers by acting on said actuation means.
  • This arrangement provides efficient balancing of the braking power between the two wheels, thus eliminating any possibility of lateral offset when the brakes are applied.
  • the connecting rod can be loosely connected at at least one of its ends with the second end of the respective lever in order to compensate for the change in the distance between the second ends of the levers when the levers are pivoted by the actuating means of brake.
  • the connecting rod is for example loosely connected at its rear end with the second end of the rear lever.
  • the pads according to the invention can be provided with a connecting pin which passes through an elongated hole formed, either in said loosely connected end of the connecting rod, or in said respective second lever end, and through a hole formed respectively, either in said second end of the respective lever, or in said loosely connected end of the connecting rod.
  • said levers are substantially parallel to each other and vertical and pivotally mounted on the chassis near their second end, said connecting means comprising a third lever pivotally mounted on the chassis, said means brake actuation being fixed to said third lever, and said third lever being connected to each of the first two levers by a traction cable.
  • the skate according to the invention shown in FIG. 1 essentially comprises a chassis 1 supported by two shafts 2 and 3 on a front wheel 4 and a rear wheel 5.
  • the chassis 1 consists of two side rails 6 whose central parts are parallel and are in a horizontal plane lower than the shafts of the wheels.
  • the side members 6 are made of bent tubes.
  • the front end 7 and the rear end 8 of the side members 6 are curved upwards and have a hole through which the respective shaft 2 or 3 passes.
  • Bolts 9 are screwed to the ends of each shaft to maintain the chassis 1 on the wheels.
  • a sole 10 of sheet steel is welded to the longitudinal members 6.
  • the sole is substantially rectangular so that the longitudinal members 6 are spaced from the width of the sole.
  • Fastening means (not shown) are mounted on the sole 10 for fixing a shoe of a user.
  • Each wheel consists of a tire 11 mounted on a rim 12.
  • Each rim has a cylindrical inner surface 13 coaxial with the respective shaft 2 and 3.
  • a tongue 14 is welded at each end of the central part of the lateral side beam 6 outside.
  • a front brake lever 15 is pivotally mounted on the front tongue 14 via a pin 16.
  • a rear brake lever 17 is mounted on the rear tongue 14 by means of a pin 18.
  • the axes 16 and 18 are horizontal and perpendicular to the axial vertical plane of the skate.
  • Each brake lever 15 and 17 has at its distal end a brake shoe 19 facing the respective cylindrical surface 13 of the rim 18.
  • a return spring 20 mounted on each axis 16 and 18 holds each lever brake in a position such that the brake pads 19 are not in contact with the cylindrical surfaces 13 as long as no action is exerted on the brake levers 15 and 17.
  • the central ends of the levers 15 and 17 are connected to a connecting rod 21.
  • the corresponding ends of the front lever 15 and of the connecting rod 21 are connected by means of a connecting pin 22 passing through two corresponding round holes in the ends lever 15 and connecting rod 21.
  • the corresponding ends of the rear lever 17 and connecting rod 21 are connected by means of a connecting pin 23 which passes through a round hole in the end of the connecting rod 21 and a horizontally elongated hole 24 in the lever 17.
  • An actuating strap 25 has its lower end mounted substantially in the middle of the connecting rod 21 and has at its upper end a clip 26 for fixing it to the belt of a user.
  • the brake levers 15 and 17 and the connecting rod 21 are aligned with each other and the connecting axes 22 and 23 are horizontal and perpendicular to the axial vertical plane of the shoe, as are the axes 16 and 18. Consequently , when a user pulls up on the strap 25, the brake levers 15 and 17 are pivoted by means of the connecting rod 21 against the return torque of the springs 20, as shown by the arrows A of Figure 1. In response to this movement, the brake pads 19 come into contact with the respective cylindrical surfaces 13 of the rims 18, which has the effect of braking the skater.
  • the pivoting movement of the brake levers 15 and 17 causes an increase in the distance between their central ends, which is possible because the connecting rod 21 and the lever 17 are loosely connected due to the presence of the elongated hole 24.
  • connection between the ends of the levers 15 and 17, and more particularly the arrangement of the connecting rod 21, causes a balanced braking effect, so that no lateral offset results therefrom.
  • the brake levers 15 ⁇ and 17 ⁇ are mounted on the substantially vertical chassis 1, pivoting at their lower end around the axes 16 and 18.
  • the brake pads 19 are mounted at the upper ends of the levers 15 ⁇ and 17 ⁇ , in oblong holes to ensure their adjustment.
  • a third lever 30 is mounted on the chassis 1 pivoting about a horizontal axis 31.
  • This lever consists of a lever rod 32 extending from the axis 31 towards the rear of the shoe, and a circular part 33 coaxial with the axis 31.
  • the lever 30 is mounted against the outer spar of the shoe on the side of the axial plane of this shoe.
  • a cutout 34 in the sole 10 allows the passage of the lower portion of the portion 33 of the lever, it protrudes as little as possible from the chassis so as not to reduce the ground clearance.
  • the end of the rod 32 receives the lower end of the strap 25.
  • Two diametrically opposite holes 35a and 35b are provided in part 33, diametrically opposite with respect to the axis 31.
  • Each of the holes 35a and 35b receives the end piece of a traction cable 36a and 36b respectively, for example a cable under sheath.
  • the cable 36a extends from the upper hole 35a backwards through a cutout 37 in the sole 10 of the shoe, then at 38 under the shoe, and it finally rises beyond the rear edge of the sole 10, towards the upper end of the lever 17 ⁇ where it is retained by another end piece in a hole 39.
  • the traction cable 36b extends from the lower hole 35b towards the front of the shoe, first at 40 under the sole 10, then beyond the front edge of the sole upwards 'at the upper end of the lever 15 ⁇ where it is retained by a nozzle in a hole 41.
  • the holes 35a and 35b, in the lever 30, are arranged so that the cables 36a and 36b are, in the vicinity of these holes, as perpendicular as possible to the diameter connecting these two holes, so as to reduce the braking stroke.
  • this diameter is inclined by 15 ° relative to the vertical.
  • Return springs may possibly be provided to keep the levers 15 ⁇ and 17 ⁇ in a position where the pads 19 do not rub on the surfaces 13.
  • a pin return spring can also be mounted on the pin 31 to return the lever 30.
  • the embodiment shown in Figure 2 also provides an excellent distribution of braking between the front and rear wheels.
  • the use of traction cables makes it possible to obtain a braking power greater than the embodiment in FIG. 1.
  • the braking stroke is also very low and the braking can be dosed at will.
