Definitions

  • This invention relates to a roller skate.
  • Roller skates can be used to perform sport or as an environmentally friendly means of transport.
  • roller skates are used for recreational purposes or sport.
  • Skates are usually made in the form of a shoe equipped in its lower portion, that is to say, the one closest to the ground, with wheels.
  • rollerblade may be arranged in line, in this case the term "rollerblade” is used or arranged in pairs on two axes to form a square (traditional roller skates). Disadvantageously, not all users are able to manoeuvre naturally on roller skates, especially in the case of roller blades.
  • the difficulty of use is due to the fact that as well as carrying out the manoeuvres for moving forward along the ground it is also necessary to pay great attention to maintaining an adequate balance.
  • roller skates comprise self-propelled systems.
  • patent US5492345 describes a self-propelled roller skate wherein the shoe rotates with respect to a lower frame pulling the rear wheel by means of a cable.
  • a major drawback is due to the fact that the cable used does not allow a fluid and natural movement and is not effective in transmitting the motion to the rear wheel, cancelling and reducing the overall energy efficiency of the skate.
  • the aim of the invention is to provide a roller skate which overcomes the drawbacks of the prior art.
  • a further aim of the invention is to provide a roller skate which allows a facilitated and more natural use also by an unskilled user with an efficient transmission of the forward motion.
  • a further aim is to provide a roller skate which, if used by persons with an average level of skill, allows higher speeds to be reached with respect to traditional roller skates or makes it possible to overcome significant slopes which would otherwise be difficult to overcome with traditional roller skates.
  • FIG. 1 is a first perspective view of a roller skate according to the invention in a first configuration of use
  • FIG. 2 is a second perspective view of a roller skate according to the invention in the same configuration of use of Figure 1,
  • FIG. 3 is a side view of the roller skate according to the invention in a second configuration of use.
  • skate 1 denotes in its entirety a roller skate which for simplicity will hereinafter be referred to as skate 1.
  • the skate 1 according to the invention comprises a first fixed frame 3 supporting at least two wheels 6, 7, advantageously three, of which at least one is associated with a respective free-wheel.
  • the drawings show an embodiment of a skate 1 comprising three wheels, a front wheel 6, relative to the direction of travel, a central wheel and a rear wheel 7.
  • the wheel associated with the respective free-wheel is the rear wheel 7.
  • the skate 1 also comprises a second movable frame 2 operatively connected to the first fixed frame 3 and configured to move relative to it at least from a first far position, shown in Figures 1 and 2, to at least one second near position, shown in Figure 3.
  • the skate 1 also comprises a pinion connected stably to the free-wheel of the wheel 7 and a rack 5 operatively connected to the second movable frame 2.
  • the rack 5 is designed to engage with the pinion to impart to it a rotary movement.
  • the pinion not illustrated in the drawings since it is interposed between the rack 5 and the wheel 7, is advantageously mounted on the axis of the wheel 7 and integral with a part of the free-wheel, also not illustrated since it inside the hub of the wheel 7.
  • the rack 5 is advantageously shaped in the form of a circular segment as shown in Figures 2 and 3.
  • the free-wheel connected to the wheel 7 transmits the rotary motion to the wheel only when the rack 5 performs the movement corresponding to the forward movement of the skate 1.
  • the free-wheel uncouples the rotary motion induced by the rack 5 not transmitting it to the pinion and, therefore, to the wheel 7.
  • the skate 1 also comprises elastic means 4 positioned between the first fixed frame 3 and the second movable frame 2.
  • the elastic means 4 comprise a suspension spring and are configured to dampen the movement of the second movable frame 2 from the first far position ( Figures 1 and 2) to the second near position ( Figure 3).
  • the presence of the elastic means 4 makes it possible to obtain a greater comfort of use of the skate 1 by the user.
  • the skate 1 advantageously also comprises an element 8 for supporting the rack 5.
  • the support element 8 is pivoted on the first fixed frame 3 by a fulcrum 15.
  • the support element 8 comprises a drive crank 12 connected to the second movable frame 2 and configured to transfer the relative movement of the second frame 2, when it passes from the first far position to the near position and vice versa, with respect to the first frame 3, to the rack 5.
  • the rack 5 being engaged on the pinion allows, lastly, the transfer of motion to the wheel 7 by means of the free-wheel.
  • the support element 8 comprises two mutually hinged portions, each of which is then connected to the first fixed frame 3, at the pivot 15, and to the second movable frame 2, at the pivot 28.
  • the upper portion is the crank 12 which is in turn pivoted on the second movable frame 2 at a respective pivot 28.
  • the lower portion of the support element 8 is, on the other hand, a fan-shaped element 25 which is pivoted at a first end on the pivot 15 and at a second end comprises the rack 5.
  • a user lifts the rear portion of the second frame 2, that is to say, the heel of the user; the second frame 2 inclines relative to the first frame 3 fixed at the pivot point 19.
  • the second frame also moves in a longitudinal direction relative to the first frame 3.
  • the above-mentioned longitudinal movement occurs by free sliding of the pin 19 in the respective linear guide 18, which is clearly shown in Figure 2.
  • the skate 1 advantageously comprises a braking system designed to limit the forward speed of the skate 1.
  • the braking system can be operated by the user by operations of a manual type or, advantageously, by the passage of the second frame 2 to a third operating position, shown in Figure 4.
  • Figure 4 shows an embodiment in which the braking system can be operated by the user, that is to say, by a movement obtained directly on the second movable frame 2.
  • the skate 1 comprises a braking lever 10 whilst the second movable frame 2 comprises an engagement element 11 configured to actuate the lever 10, for example by physical contact, when the second movable frame 2 adopts the third operating position of Figure 4.
  • the third operating position of the second movable frame 2 relative to the first fixed frame 3 corresponds to a position wherein the second frame 2 is inclined relative to the first far position and said second near position (that is to say, the operating positions for the forward movement of the skate on the ground).
  • the braking position (shown in Figure 4) entails raising the front portion of the second frame 2 (that is to say, the tip of the user's foot) relative to the first frame 3.
  • the braking system comprises a disc type system, comprising a disc 14 and a respective gripper 13.
  • the disc 14 and the respective gripper 13 are installed at the rear wheel 7 on the opposite side relative to the pinion and the free-wheel.
  • the gripper 13 is connected to the lever 10 advantageously through a hydraulic cable or conduit 26.
  • the drawings show a wearable element 20 which can be made in the form of a shoe and installed by threaded connections 21 of known type on the second movable frame
  • the second movable frame 2 in this regard comprises adjusting means, for example a plurality of fixing seats, to be able to adapt the skate 1 to different sizes of the wearable element 20.
  • the invention achieves the preset aims, overcoming the drawbacks of the prior art.
  • the skate 1 according to the invention allows a more natural and effective use both by skilled and unskilled users in the sport of roller skating.
  • the rack 5 always engaged on the pinion makes it possible not to have jerks in the operation of the skate 1 making the use more fluid and faster.
  • a further advantage of the invention is that it provides a roller skate which is a true means of traction transport identified by the regulations as a pace accelerator, that is to say, a means of transport which does not constitute an obstruction since it has muscular and individual activation.
  • roller skate according to the invention is identified as a pace accelerator allows it to circulate anywhere, including pavements and pedestrian areas.
