Definitions

  • the present invention relates to a skate with in-line wheels.
  • Conventional skates with in-line wheels generally comprise a frame, supporting a plurality of in-line wheels and which is substantially U-shaped so as to form at least one supporting base for all or part of the sole of a rigid or semirigid shoe.
  • Two lateral wings protrude downwards from the base of the frame,and a plurality of wheels are pivoted thereto by means of fixed pivots between said wings and are thus arranged in-line with respect to each other.
  • a roller skate has two wheels articulated by means of levers constituted by pairs of brackets which surround the wheels.
  • the brackets are articulated, through their open ends, to a flat plate constituting the frame of the skate.
  • each bracket has a plurality of fixing points for selecting and setting the preloading of the springs, so as to match the different forces applied by the user, and of the stroke limits for limiting the deflections of the spring-loaded levers.
  • US-920,848 illustrates a skate with in-line wheels and having a supporting plate for a shoe which can be locked thereat by means of adapted tensioning straps. Lateral bars protrude from the plate and are connected by a first strap for supporting the rear part of the user's leg and by a second strap which surrounds the calf and can be secured thereto.
  • Two arms are pivoted below the plate at one end and have supports for a wheel, said arms interacting, at the other end, with a spring interposed between said arms and the plate that constitutes the frame.
  • EP-545,250 relates to a braking device for skates with in-line wheels wherein a supporting frame for a shoe is provided, in a downward region and centrally, with a tab whereto the ends of two pairs of bars are pivoted. Wheels are pivoted to the bars and a flexible element is interposed in the interspace between two adjacent wheels of each pair of bars, said element being connected below the overlying frame at its other end.
  • WO96/26775 discloses a skate with in-line wheels provided with a frame whereto two curved trucks are pivoted at the regions below the toe and the heel.
  • the wheels are pivoted to the ends of the trucks and the trucks can thus oscillate with respect to the frame and can be provided with spring-loaded or rubber-pad shock-absorbers, for shock-absorbing the truck particularly when, by oscillating about the frame pivot, it abuts against said frame with one end.
  • An aim of the present invention is therefore to overcome the above-described drawbacks and to solve the above problems by providing a skate with in-line wheels comprising a substantially U-shaped frame supporting, in an upward region, a rigid or semirigid shoe and allowing to achieve optimum shock-absorbing of the wheels, thus allowing to optimally cushion the vibrations and/or stresses affecting the wheels.
  • An important object of the present invention is also to provide a skate with in-line wheels wherein the user can select the degree of shock-absorbing according to individual specific requirements or according to the course to be followed.
  • a further object of the present invention is to provide a skate with in-line wheels which at the same time allows to achieve optimum transmission of forces from the shoe to the wheels.
  • a further object of the present invention is to provide a skate with in-line wheels wherein it is possible to selectively vary the position of the rotation axis of at least one wheel.
  • a further object is to provide a skate with in-line wheels having a simple constructive structure and which is easy to industrialize.
  • a further object is to provide a skate with in-line wheels wherein the user can immediately perceive the intended and selected degree of shock-absorbing applied to the wheels.
  • a skate with in-line wheels comprising a substantially U-shaped frame which forms at least one base, above which a shoe is associated, and two lateral wings protruding downwards the ground, characterized in that at least one separate truck for supporting at least one wheel is slidingly associated with said frame in contrast with at least one flexible and interchangeable element.
  • the reference numeral 1 designates a frame of a skate with in-line wheels, said frame being substantially U-shaped in transverse cross-section, so as to form at least a first base 2 for supporting a shoe and two first lateral wings, designated by the reference numerals 3a and 3b, which are parallel to each other and directed towards the ground 4.
  • a first truck 5 and a second truck 6 are slidingly associated with the frame 1.
  • Each truck is U-shaped and comprises a second base 7 which is approximately as wide as the interspace between the inner lateral surfaces 8 of the fast lateral wings 3a and 3b.
  • Two second side wings 9a, 9b protrude from the second base 7 and are parallel to each other.
  • the first truck 5 and the second truck 6 can therefore be inserted at the frame 1 and the second lateral wings 9a and 9b can slide with respect to the first lateral wings 3a and 3b.
  • the second lateral wings 9a and 9b protrude beyond the lower perimetric edge 10a and 10b of the first lateral wings 3a and 3b, and a pair of first pivots 12 for pivoting wheels 13 is transversely associated along parallel axes proximate to the free ends 11a, 11b of the second lateral wings 9a and 9b.
  • the wheels have of course such dimensions that they can be contained in the interspace between the second lateral wings 9a and 9b without interacting with the second base 7 of each truck.
  • Each one of said first and second trucks has a means for guiding it during its sliding inside the frame 1, said means being constituted by a second pivot 14 transversely pivoted to each second base 7 in the interspace between the two adjacent wheels 13, the ends or said second pivot being accommodated in, and interacting with, a pair of adapted first seats 15a and 15b formed at the first lateral wings 3a and 3b of the frame 1 along an axis approximately perpendicular to the ground 4.
  • the first and second trucks slide with respect to the frame 1 in contrast with first and second flexible elements interposed between the second base 7 and the first base 2.
  • the first flexible elements are constituted, for each truck, by a first pair 16a, 16b and by a second pair 17a, 17b of cylindrical helical compression springs arranged transversely to the second base 7, respectively proximate to the front and rear ends 18 and 19 of each second base 7.
  • Said first and second pairs of springs are interchangeable and are accommodated at adapted pairs of second seats 20 and third seats 21 formed at the first lateral wings 3a and 3b.
  • Said first and second pairs of springs are also advantageously used to cushion part of the load and therefore interact both with part of the second base of the first and second trucks and optionally with part of the first lateral wings 3a and 3b, as shown in figure 2.
  • the second flexible elements interposed between the second base of each truck and the first base of the frame are constituted by a third pair of Belleville spring washers or rubber pads, designated by the reference numerals 22a and 22b, which are arranged at the longitudinal median axis of the second base 7, in the interspace between the second pivot 14 and the front and rear ends 18 and 19.
  • said third pair of Belleville spring washers or rubber pads is meant to cushion the remaining part of the load.
  • Both the first flexible elements and the second flexible elements may of course be replaced with others having a different load or a different compressive strength.
  • FIG. 3 illustrates a frame 101 wherein the first pair of springs 116 and the second pair of springs 117 are again interposed between the second base 107 of each first and second truck 105 and 106 and the first base 102 of the frame 101; the axis of said first and second pairs of springs, however, is inclined with respect to said first and second bases.
  • first seats 115a and 115b formed on the first lateral wings 103a and 103b are inclined along the same axis.
  • first and second pairs of springs are interposed between first raised portions 123 and second raised portions 124 which protrude, respectively from said first base 102 and from said second base 107, along planes inclined at right angles with respect to the plane of arrangement of the ends of each one of said first and second pairs of springs.
  • the inclination of the first and of the second pairs of springs and of the first seats allows, in case of collision of the wheels with stones or other objects protruding from the ground, to cushion the main component of the impact force. If the skater performs lateral thrusting in order to increase his or her speed, the inclination allows to transmit a large extent of force to the wheels, wasting a limited amount of energy.
  • Fig. 4 illustrates another embodiment for a frame 201, wherein each individual wheel 213 is pivoted transversely at the second lateral wings 209a, 209b of a single truck, generally designated by the reference numeral 205, which is slidingly associated between the first lateral wings 203a and 203b of the frame 201 along an axis which is perpendicular or, as shown in figure 4, at an angle with respect to the first base 202 of the frame 201.
  • Each wheel 213 is pivoted at a second pivot 214 the ends whereof are located at adapted first seats 215a, 215b arranged at an equal angle with respect to the truck 205.
  • each truck 205 slides not only between said first wings 203a, 203b but also between a pair of adapted tabs 225a, 225b protruding below the first base 202 towards the ground along an axis which is parallel to the plane of arrangement of the truck, the pair of tabs being arranged transversely to the first lateral wings 203a, 203b, and the front end 218 and rear end 219 of each truck interacting with said pair of tabs.
  • the dimensions of the pair of tabs are of course such as to allow normal rolling of the wheels.
  • first flexible elements are interposed between the second base 207 of each truck and the overlying first base 202 of the frame and are constituted by a single spring 216 interposed between said second base and first raised portions 223 protruding from the first base 202.
  • This embodiment too, therefore solves all of the intended aim and objects, the customization of the obtainable degree of cushioning for each individual wheel being even greater.
  • Figs. 5 and 6 illustrate a further embodiment of the present invention for a skate 326 comprising a shoe 327 the sole 328 whereof is associated, preferably at two regions, on the first base 302 of the frame 301, said frame also comprising a pair of first lateral wings 303a and 303b which protrude towards the ground 304.
  • This embodiment too, comprises a first truck 305 and a second truck 306 which are identical to each other, are slidingly associated with the frame 301, and have second lateral wings 309a, 309b which can slide within the first lateral wings 303a, 303b.
  • the wheels 313 are pivoted transversely, by means of first pivots 312, proximate to the free end 311a and 311b of the second lateral wings 309a and 309b.
  • a flap 329a and 329b protrudes from both of the second lateral wings 309a and 309b above the pivoting axis of the first pivots 312; said flaps arrange themselves approximately parallel to the overlying lower perimetric edge 310 of the first wings 303a, 303b.
  • Adapted second seats 320 for first flexible means constituted by first pairs of springs 316a, 316b and by a second pair of springs 317, are formed at the lower perimetric edge 310a, 310b of the first wings 303a, 303b which are adjacent to the flaps 329a, 329b, proximate to the front end 318 and rear end 319 of the first truck 305 and of the second truck 306.
  • the first truck 305 and the second truck 306 again have a second pivot 314 transversely connecting the second wings 309a, 309b; said ends are accommodated at first seats 315 which are substantially slotted with an axis which is approximately perpendicular to the ground 304.
  • a second flexible element can be interposed in the interspace between the second base 307 and the first base 302 and is constituted by a third pair of springs or pads 322a, 322b which can be removed and have, in a longitudinal sectional view, substantially an isosceles-trapezoid configuration allowing to vary the rotation axis of one or more wheels in an upward direction or in a downward direction.
  • the second pair of springs or pads can of course be accommodated at the interspace between the first and the second bases by providing an opening 341 at one of said second lateral wings, as shown in figure 6.
  • the pads 322a, 322b can be replaced either by removing them through the opening 341 or after extracting the second pivot 314 and then removing the truck from the frame.
  • skate according to the invention is susceptible of numerous modifications and variations, within the scope of the appended claims.
  • the materials and the dimensions constituting the various individual components of the skate may also vary according to particular requirements.
