Definitions

  • the present invention relates to a roller skate frame, namely to a frame for an in-line roller skate.
  • the present invention relates to a roller skate frame made of light metal, e.g. aluminium, obtained by press moulding from a single metal sheet.
  • an in-line roller skate frame comprises a supporting surface intended to receive and support the skate boot and a pair of side wings, between which a plurality of aligned wheels are mounted.
  • Said frame should have a high mechanical strength so as to effectively and reliably support the user's weight; at the same time, it should be as light as possible, so as to improve the user's comfort and avoid unnecessary efforts.
  • manufacturing of said frame should be simple and cheap and it should allow to obtain a wide variety of different frame patterns, even complicated ones, so as to satisfy the aesthetical requirements of the users.
  • Frames made of plastic or metallic material by casting molten material in a mould are known in the art.
  • Frames comprising a plastic material supporting base and a pair of metallic side wings fastened to said supporting base by means of screws, rivets or the like are known.
  • said frames are subject to the risk of losing their mechanical stiffness, for instance when the screws used for fastening the side wings to the supporting base become loose.
  • the main object of the present invention is to provide a roller skate frame that has a satisfactory mechanical strength while being light and comfortable, so as to allow to overcome the drawbacks of known frames.
  • a further object of the present invention is to provide a roller skate frame that can be obtained by a simple and cheap manufacturing process.
  • roller skate frame according to the invention, as claimed in the appended claims.
  • the Applicant has noticed that a high mechanical strength is not required throughout the whole length of the skate frame, but only at some portions thereof, where the user's weight concentrates while skating, and more particularly at the toe-supporting portion thereof.
  • the roller skate frame is obtained from a thin metallic sheet and a portion of greater thickness is provided at the toe-supporting portion thereof.
  • the frame according to the invention can be made from a light metal sheet, e.g. an aluminium sheet, so as to have limited weight.
  • the greater thickness at the toe-supporting portion of the frame is obtained by providing at the toe-supporting portion of the frame a first and second bridging plates, each integral to a respective side wing and projecting inwardly therefrom, said bridging plate being sized so as to overlap each other and being fastened to each other at the longitudinal axis of said toe-supporting portion.
  • the greater thickness at the toe-supporting portion of the frame is obtained by providing at the toe-supporting portion of the frame a single bridging plate of greater thickness, integral to a side wing, projecting inwardly therefrom and fastened to the other side wing.
  • a toe-supporting portion and a heel-supporting portion having different height can be obtained.
  • a heel-supporting portion having a height higher than the toe-supporting portion can be obtained, so that the skate frame is more ergonomic and comfortable for the user's foot.
  • a roller skate frame according to a preferred embodiment of the present invention is indicated by numeral 1.
  • Said frame 1 is preferably manufactured from a metallic sheet, appropriately press-moulded. More particularly, said frame 1 is preferably made from a metallic sheet of a light metal such as aluminium.
  • Said frame 1 comprises a supporting base 3 intended to support the skate boot and a pair of side wings 5a,5b, suitable for receiving therebetween a plurality of aligned wheels.
  • said side wings 5a,5b are provided with aligned through-holes, 7a,7b respectively, that can house the opposite ends of the axles carrying said wheels.
  • Side wings 5a,5b can be shaped in a wide variety of different patterns, so as to satisfy the aesthetical sense of the users. More particularly, said wings can advantageously have openings 9 that contribute to reduce the frame weight, while conferring to the frame itself a distinctive aesthetical appearance.
  • the supporting base 3 does not extend throughout the whole length of the frame. On the contrary, it consists of a first supporting portion 3a for the toe portion of the skate boot (toe-supporting portion 3a) and of a second supporting portion 3b for the heel of the skate boot (heel-supporting portion 3b), separated by a central window 4.
  • the toe-supporting portion 3a of the supporting base 3 is configured so as to have a thickness considerably greater than the rest of frame 1.
  • the supporting base 3a is obtained by providing a pair of separate bridging plates 11a,11b, each integral to a respective side wing 5a,5b and projecting inwardly towards the longitudinal axis L of the frame 1.
  • the toe-supporting portion 3a turns out to have a thickness that is twice the thickness of the rest of frame 1, so that the mechanical strength of the frame 1 at this portion is considerably increased.
  • one of these plates - namely the bridging plates indicated with numeral 11b in Figures 1 - 3 - is provided with a pair of tabs 13, extending in a transverse direction with respect to said plate, which can be wrapped around the overlapping bridging plates 11a,11b and clinched thereto.
  • the heel-supporting portion 3b is provided with a through-hole 15 for fastening means (e.g. a screw) for fastening the frame 1 to a skate boot.
  • fastening means e.g. a screw
  • each bridging plate 11a, 11b is provided with a through-hole 17a,17b, said through-holes 17a,17b being aligned when the plates are overlapped, so that fastening means for fastening the frame 1 to the skate boot can be inserted therethrough.
  • said through-holes 17a,17b can also be used as reference points for correctly overlapping the bridging plates.
  • the heel-supporting portion and the toe-supporting portion necessarily have the same height.
  • the provision of separate, overlapping bridging plates 11a,11b forming the toe-supporting portion 3a allows to obtain supporting portions having different heights.
  • the heel-supporting portion 3b can be higher than the toe-supporting portion 3a, thus allowing to obtain a roller skate which is considerably more ergonomic and comfortable.
  • the toe-supporting portion 3a is obtained by providing a single bridging plate 11a, integral to a first side wing 5a and projecting inwardly towards the longitudinal axis L of the frame 1 and the second side wing 5b.
  • the end of the bridging plate 11 is bent downwards so as to be wrapped around the outer face of said second side wing 5b and fastened thereto by means of a pin 19.
  • the end of the bridging plate 11 can be bent downward so as to lean against the inner face of said second side wing 5b and be fastened thereto by means of a pin.
  • the bridging plate 11 has a thickness s 2 that is noticeably greater than the thickness s 1 of the rest of the frame 1.
  • the bridging plate 11 has a thickness s 2 that is twice the thickness s 1 of the rest of frame 1.
  • the thicker bridging plate 11 can be obtained by providing a zone of greater thickness in the metallic sheet during the press-moulding. Otherwise, it can be obtained by providing a longer metallic strip and then folding it on itself for obtaining the thicker plate. Alternatively, the greater thickness of this plate can be obtained by any other conventional technique known in the art.
  • supporting portions having different heights can be obtained. More particularly, the heel-supporting portion 3b can be higher than the toe-supporting portion 3a, allowing to obtain a roller skate which is considerably more ergonomic and comfortable.
  • the present invention allows to achieve the above-mentioned objects, by providing a roller skate frame that guarantees the necessary mechanical strength for supporting the user's weight, while being light and comfortable.
