Definitions

  • the present invention relates to a skate with aligned wheels.
  • a first conventional type of skate with aligned wheels has a support for an item of footwear from which two longitudinal shoulders protrude; a plurality of aligned wheels is pivoted between the shoulders.
  • This first conventional skate has some problems: the fact that the aligned wheels are pivoted in a fixed manner to the pair of wings entails a direct transmission to the item of footwear of all the stresses due to the uneven parts of the ground encountered during sports practice, with consequent discomfort for the user.
  • the structural rigidity of this known solution furthermore entails the transmission of vibrations to the item of footwear and therefore to the legs of the user which hinder his/her sports performance.
  • a sports implement which is predominantly used by skiers for summer practice on roads and is composed of a support for an item of footwear from which a frame protrudes downward and centrally.
  • the ends of two pairs of wheel supporting trucks are independently pivoted to the frame, and the head of a screw with a threaded stem is connected to the support in the interspace between two adjacent wheels.
  • a complementarily threaded nut is associated with the threaded stem and abuts on the ground-facing surface of a connecting element which is arranged transversely to each pair of trucks.
  • a cylindrical helical compression spring is arranged coaxially to the stem.
  • the adjustment of the degree of packing of the spring only allows to vary the condition of use of the implement during the sports practice of slalom; when the adjustment of the spring is at its minimum setting, i.e. when the spring is not compressed, it is in fact possible to achieve easy use for the practice of slalom, but one also observes yielding during pushing and when traveling along straight paths, with a considerable degradation of athletic performance.
  • a further disadvantage of this solution resides in the fact that the placement of the springs with respect to the pivoting points of the wheel supporting trucks is decisive for the good operation of the device, since the springs are arranged further outward than the fulcrums in order to be able to act by compression.
  • the length of the support for the sole must also be such as to allow its interaction and/or fixing with respect to the springs, and this limits the field of application to the larger shoe sizes.
  • the aim of the present invention is therefore to eliminate the problems described above in conventional types by providing a skate which allows to reduce the stresses transmitted to the legs of the user, caused by rough or uneven ground, keeping the position of the wheels constant with respect to the ground.
  • Another important object is to provide a skate which optionally allows the user to preset the degree of attenuation of said stresses according to a specific use.
  • a further object is to make the positioning of the elastically deformable elements and of the fulcrums of the wheel supporting trucks mutually independent, reducing bulk and simplifying the structure of the skate.
  • Another object is to provide a skate which can be used for any range of sizes.
  • Yet another object is to provide a skate which does not transmit the stresses of the truck directly to the sole support and allows to improve the comfort for the user.
  • Another object is to provide a skate which is structurally simple and easy to assemble.
  • a further object is to provide a skate which is easy to industrialize, reliable and safe in use and has low manufacturing costs.
  • a skate with aligned wheels comprising a support for an item of footwear from which a frame protrudes downward, characterized in that a pivoting pin for the facing end of a wheel supporting truck is associated transversely at at least one end of said frame, at least one means suitable to control the mutual oscillation of said frame and said truck being interposed between said truck and said frame.
  • said means is constituted by an elastically deformable element and/or by a movable slider.
  • the skate generally designated by the reference numeral 1, comprises a support 2 for an item of footwear 3 from which a frame 4 protrudes downward.
  • the frame is constituted by a first wing 5 which is preferably shaped like an inverted trapezoid with the shorter parallel side 6 directed toward the ground 7.
  • a pivot 10 is transversely associated with the frame 4, at at least one end 8, at the first surface 9, which is lateral and preferably inclined with respect to the ground 7, and proximate to the connecting point between said first surface and the shorter parallel side 6.
  • the means is constituted by an elastically deformable element, such as a spring 15 which is arranged coaxially to the pivot 10 and has ends 16 and 17 which respectively interact in abutment with an adapted first lug 18, which protrudes, internally or externally, with respect to the frame 4, and are arranged between a pair of shoulders 19 which are mutually parallel and are formed internally or laterally with respect to the truck 13.
  • the spring 15 acts so as to mutually space the truck 13 and the frame 4.
  • a second wing 20 protrudes from the frame at the end 11 to which the pivot 10 is pivoted and toward the frame 4.
  • the second wing 20 oscillates between a second lug 21 and a third lug 22 which protrude internally or externally with respect to the frame 4.
  • a controlled oscillation within the frame 4 is thus allowed to the second wing 20.
  • a third wing 30 protrudes from the second surface 12 toward and within the frame 4 to guide the mutual sliding.
  • the skate according to the invention has achieved the above aim and objects, a skate with aligned wheels having been obtained which allows to reduce the stresses transmitted to the legs of the user as a consequence of rough or uneven ground; the skate being structurally simple, easy to assemble and industrialize and having modest manufacturing costs.
  • the placement of the spring 15 between the frame and the truck allows to adopt this solution even for small shoe sizes, because the length of the sole support is not linked to the extension of the truck.
  • the sole support can also be made of semirigid material, such as plastics, because it does not have to directly withstand the stresses of the spring, as instead occurs in the known art.
  • figures 3 and 4 illustrate a second embodiment of a skate 101 in which an adapted first seat 123 and a second seat 124 are formed, at the first surface 109 and at the second surface 112, for an elastically deformable element such as a cylindrical helical compression spring 115.
  • the spring 115 preferably has an axis defined approximately along an arc of a circle centered in the rotation point 110 of the truck 113, so as to compress optimally upon stresses imparted to the wheel 114.
  • the stroke limit is defined by the direct interaction between the first surface 109 and the second surface 112 or by the interaction of the second wing 120 with the third lug 122, as shown in figure 4.
  • Figures 5 to 9 illustrate a third embodiment of a skate 201, wherein the means suitable to control the mutual oscillation between the first surface 209 of the frame 204 and the facing second surface 212 of the truck 213 is constituted not only by an elastically deformable element, such as a spring 215 arranged coaxially to the pivot 210, as shown in the first embodiment, but also by a slider 225.
  • an elastically deformable element such as a spring 215 arranged coaxially to the pivot 210, as shown in the first embodiment, but also by a slider 225.
  • the slider has a stem 226 which can slide within a first slot 227 which is substantially L-shaped having a longer wing 228 arranged along an axis which is preferably approximately parallel to the plane of arrangement of the lateral surface 209.
  • the stem 226 also slides within a second longitudinal slot 229 formed on a third wing 230 which protrudes from the second surface 212 toward and within the frame 204, the second slot having such a shape as to be able to arrange itself at the longer wing 228 of the first slot 227.
  • first slot and of the second slot may be reversed, the first slot affecting the third wing 230, in this case with the shorter side of the L directed toward the tip of the truck 213, the second slot being formed at the frame 204.
  • Figure 10 illustrates a further embodiment of a skate 301 whose frame 304 has, at at least one end 308, at the first surface 309, which is lateral and preferably arranged along a plane which is approximately perpendicular to the plane of the ground 307, a pair of shoulders 331 which are mutually identical and parallel and protrude in a direction which is approximately at right angles to the first surface 309.
  • the first surface 309 and the second surface 312 thus face one another, and a first protrusion 332 and a second protrusion 333 protrude respectively from the surfaces at right angles, approximately at the same axis.
  • a means suitable to control the mutual oscillation of the frame and of the truck is interposed coaxially to said protrusions and is constituted by an elastically deformable element such as a spring 315.
  • the spring is compressed optimally, absorbing the stresses imparted to the truck by the wheel 314.
  • the stroke limit is defined by the direct interaction between the lower surface of the support 302 and the underlying third upper surface 334 of the truck 313.
  • Figure 11 illustrates a further embodiment of a skate 401 which comprises a frame 404 which has a first surface 409 preferably arranged along a plane which is approximately at right angles to the plane of arrangement of the ground 407.
  • a pair of shoulders 431 protrudes approximately at right angles from said first surface.
  • the pair of shoulders 431 is adjacent to the lower surface of the support 402.
  • the adjacent end 411 of a truck 413 which supports one or more wheels 414 is transversely pivoted, by means of a pivot 410, at the pair of shoulders 431.
  • a cavity 435 is formed at the end 411 in a region adjacent to the ground 407 and acts as seat for a fourth wing 436 which protrudes at right angles to the first surface 409 of the frame 404.
  • the fourth wing 436 is positioned within the cavity 435 by means of an adapted first hole 437 defined on the truck.
  • a washer 440 can also be arranged within the cavity 435, so that it can be removed by means of an adapted screw 438 which can be inserted through said truck through an adapted second hole 439 formed thereon.
  • the washer is arranged on the head of said fourth wing 436.
  • a means suitable to control the mutual oscillation of the frame and the truck constituted by a spring 415, can thus be arranged within the cavity 435 coaxially to said fourth wing 436.
  • a further embodiment of a skate 501 is illustrated at figure 12.
  • the skate 501 has, at at least one end, a first surface 509 arranged approximately at right angles to the ground 507 and from which a pair of shoulders 531 protrudes in a region adjacent to the lower surface of the support 502.
  • the end 511 of a truck 513 is transversely pivoted between the shoulders by means of an adapted pivot 510.
  • a fourth surface 541 which faces the second surface 512 of the truck 513.
  • a first seat 523 and a second seat 524 are respectively formed at the fourth and second surfaces, and a first crosspiece 542 and a second crosspiece 543 are arranged between the seats.
  • a means suitable to control the mutual oscillation of the frame and the truck is interposed at said crosspieces and is constituted by a cylindrical helical extension spring 515.
  • skate structure may be the most appropriate according to the specific requirements.
