Abstract
Description
- The present invention relates to a shell, particularly for sports shoes such as, for example, a skate.
- Shells made for example of plastics or carbon and constituted by a single body, obtained by molding, are currently known.
- A conventional shell is shaped complementarily to the foot, so as to wrap around its sole, tip and heel, and also covers the region located proximate to the malleoli.
- In conventional skates, a soft shoe, an upper cuff, and a lower frame for connection to a plurality of wheels or to a blade for gliding over ice, are associated with such conventional shell, which is rigid.
- However, such conventional structure requires providing, for each skate size, a specific mold suitable to obtain the corresponding shell having the required size.
- Moreover, in order to offer better comfort to the user, in some cases the shells are produced also in intermediate sizes between two successive standard sizes, but this requires the use of additional padding to compensate for the greater space.
- The need to provide as many molds as there are sizes, entails even higher costs if one wishes to manufacture skates in intermediate sizes.
- Accordingly, the manufacturing process described above, suitable to obtain conventional shells, clearly has the drawback of requiring a large number of molds.
- Such drawback therefore translates into a high production cost for each individual shell and accordingly also translates into a high production cost for the sports shoe.
- Moreover, when the number of required items per size varies, the time required to reset the machines is long, and this entails a further increase in production costs.
- The aim of the present invention is therefore to solve the noted technical problems, eliminating the drawbacks of the cited prior art, by providing a shell that can be produced with reduced production costs particularly for manufacturing roller skates and ice skates.
- An important object of the invention is to provide a shell that allows to reduce the number of molds required to produce shells of every required size.
- Another important object is to provide a shell that allows high flexibility in the production of shells for sports shoes by allowing to vary the number of manufactured items per size rapidly and with shorter machine resetting times.
- Another object is to reduce inventory costs and simplify inventory management.
- Another object is to provide a structurally simple shell that can be obtained with conventional machines.
- This aim and these and other objects that will become better apparent hereinafter, are achieved by a shell, particularly for sports shoes, characterized in that it has a size, preselected during production, that is obtained by selectively connecting to a central body for supporting the sole of the foot a separate front toe portion and a separate rear heel portion.
- Further characteristics and advantages of the invention will become better apparent from the detailed description of a particular embodiment, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- Figure 1 is a perspective exploded view of the shell according to the invention;
- Figure 2 is a perspective view of the shell;
- Figure 3 is a side view of the shell according to the invention.
-
- With reference to the above cited figures, the
reference numeral 1 designates a shell, particularly usable in the manufacture of sports shoes, such as for example in-line skates or ice skates. - The
shell 1 comprises acentral body 2, for supporting the sole of the foot, constituted by afirst surface 3, shaped approximately complementarily to the sole of the foot, and from which twowings - The first front end 5a and the second rear end 5b of the
central body 2 are substantially flat and the toes or the metatarsal region and the heel of the foot protrude from thefirst surface 3. - The
central body 2 is associated with aseparate toe portion 6, arranged at the front, and with a separaterear heel portion 7. - The
toe portion 6 has a secondflat surface 8, from which a second raised rim, designated by thereference numeral 9, for containing the tip of the user's foot protrudes laterally and frontally. - The
heel portion 7 is constituted by a thirdflat surface 10, from which a third raised rim designated by thereference numeral 11 protrudes laterally and to the rear, in order to contain the user's heel. - The first and second ends 5a and 5b of the
central body 2 are arranged above the second and thirdflat surfaces toe portion 6 and of theheel portion 7, so that the second and third raisedrims wings perimetric rim 12 which contains the foot and prevents lateral movements thereof. - The shape of the
central body 2, of thetoe portion 6 and of theheel portion 7 is such that they can be selectively mutually associated, thetoe portion 6 and theheel portion 7 being able to slide longitudinally with respect to thecentral body 2, as schematically shown in Figure 3. - Once the position of the
toe portion 6 and of theheel portion 7, with respect to thecentral body 2, has been determined, according to the required size, the toe and heel portions may be fastened to the central portion. - In this manner it is possible to obtain shell structures of different sizes, so as to cover at least two successive sizes, without the need to have a mold for each size, including intermediate sizes.
- It is in fact sufficient to have a mold for each one of the three parts that compose the invention; in this manner, one also has a distinct reduction in the space required for inventory and in the minimum number of parts in stock, with a substantial cost reduction.
- It has thus been found that the invention has achieved the intended aim and objects, a shell having been provided that allows to reduce production costs for the manufacture of shells for sports shoes, since it reduces the number of molds required to manufacture shells of any required size and also reduces inventory costs while simplifying inventory management.
- The invention also allows high flexibility in the manufacture of shells for sports shoes, since it is possible to vary the number of items manufactured per size simply by acting on the procedures for mutually connecting the central body, the toe portion and the heel portion.
- The materials used, as well as the dimensions that constitute the individual components of the invention, may of course be more pertinent according to specific requirements.
- The disclosures in Italian Utility Model Application No. TV2001U000014 from which this application claims priority are incorporated herein by reference.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
