Definitions

  • the present invention relates to a frame particularly for skates provided with in-line wheels.
  • WO 97/02072 discloses a skate having a shoe associated with a frame which has two mutually parallel lateral wings. Each wing has a substantially elliptical configuration so as to form a leaf spring in which one portion is connected to the shoe while the wheels are pivoted to the other portion and are arranged mutually in-line.
  • the above frame entails a considerable drawback for the user, since skating inherently and necessarily entails the need to have adequate lateral support.
  • the elasticity of the wings of the frame required to absorb the stresses, limits the lateral support particularly during thrusting and during sideslip braking.
  • An aim of the present invention is to solve the mentioned problems, eliminating the drawbacks of the cited prior art and thus providing a skate having a frame which allows to simultaneously achieve good absorption of the stresses applied to the wheels by uneven regions (in the ground) and optimum lateral rigidity.
  • An important object of the invention is to provide a skate having a frame which allows to achieve optimum skating control.
  • a further important object is to provide a skate having a frame which allows to perform thrusting and sideslip braking in an optimum manner.
  • a further object is to provide a frame which allows correct, effective and safe use of the skate.
  • a frame particularly for skates comprising a pair of wings, each having an elliptical shape so as to form an upper elastic portion and a lower elastic portion between which mutually in-line wheels are rotatably associated, characterized in that it comprises at least one lateral stiffening and guiding element which is slidingly interposed between said upper and lower elastic portions.
  • 1 designates a skate constituted by a shoe 2 composed of an upper 3 with which a quarter 4 is rotatably associated.
  • the upper 3 is connected to a frame 5 which has a first base 6 and a second base 7 for supporting the tip region 8 and the heel region 9 of the upper 3.
  • the frame 5 is also constituted by two wings 10a and 10b, each of which has an elliptical shape so as to form an upper elastic portion 11 and a lower elastic portion 12 which are mutually connected at their ends.
  • the upper elastic portions 11 are mutually connected at least at the first base 6 and at the second base 7, so that they can be arranged approximately parallel to each other and can accommodate, in the interspace between the wings 10a and 10b, two or more wheels 13, which are thus mutually in-line and are pivoted, by means of pivots 14, at the lower elastic portions 12.
  • the frame comprises at least one lateral stiffening and guiding element, designated by the reference numeral 15, which is slidingly interposed between the upper elastic portions 11 and the lower elastic portions 12.
  • the lateral stiffening and guiding element 15 is substantially U-shaped, so as to form a third base 16 which is preferably located at the central region that lies below the upper in the interspace between the upper elastic portions 11.
  • Two tabs 17a and 17b protrude from the third base 16 and preferably have, in plan view, the shape of a triangle wherein the vertex is directed towards the ground 18.
  • the tabs have a first portion which is associated, so that it can slide freely, at seats 19a and 19b formed at a cross-member 20 that connects the upper elastic portions 11; the tips are instead located outside the lower elastic surfaces 12 and are mutually connected at the pivots 14 for the pivoting of the wheels 13.
  • Said element 21 can also act as a stroke limiter for the vertical movement of one or more wheels, particularly the central wheels, preventing them from touching the lower surface of the upper 3.
  • the frame allows to achieve optimum skating, performing correct thrusting and effective sideslip braking by means of the optimum lateral rigidity of said frame due to the presence of the guiding and lateral stiffening element 15, without altering the characteristics in terms of absorption of the stresses provided by the elliptical configuration of the wings 10a and 10b.
  • a skate is therefore obtained which allows the user to achieve optimum control thanks to a better response, which is achieved by means of the configuration of the frame associated with the shoe.
