Description
- The present invention relates to a sports shoe, such as for example a roller skate or ice skate.
- Adjustable-size skates are currently commercially available which are usually constituted by a shell divided into a heel unit and a separate toe unit, which are slidingly associated along an axis that lies longitudinally to the shoe.
- A supporting frame for an ice-skating blade or for a plurality of wheels is associated with the heel unit in a downward region.
- The user can insert his foot within a soft innerboot that is accommodated inside the shell and can then fasten his foot inside the sports shoe by activating closure means arranged transversely to the shell or transversely to the two flaps of the soft innerboot.
- Said soft innerboot further has means that are elastically deformable at least in a longitudinal direction in order to allow an elongation that is equal to the elongation of the shell.
- The main drawback of this known type of sports shoe is the fact that a selected elongation of the shell, obtained by sliding the toe unit forward with respect to the heel unit, is often not matched by an equally effective elongation of the soft innerboot.
- Accordingly, there is the drawback of having available a known type of sports shoe that can be used comfortably for only part of the size range and not all over the size range for which the shoe was designed.
- In particular, the elongation of the soft innerboot often must be achieved by inserting the foot in such innerboot, with consequent user discomfort.
- Another important drawback consists in that due to manufacturing requirements the shell often does not surround the soft innerboot completely but does so only partially at the toe and heel.
- Thereby, a further drawback is due to the fact that the exposed parts of the soft innerboot can be subjected to wear or damage.
- The aim of the present invention is therefore to solve the noted technical problems, eliminating the drawbacks of the cited known art, by providing a sports shoe of adjustable size that allows the user to have at his disposal all the sizes planned during design.
- Within this aim, an object of the present invention is to provide a sports shoe that is comfortable to wear regardless of the preset size.
- Another important object of the present invention is to provide a sports shoe that allows to protect the soft innerboot against wear and any damage.
- Another object of the present invention is to provide a sports shoe that is structurally simple and has low manufacturing costs.
- This aim and these and other objects that will become better apparent hereinafter are achieved by a sports shoe, comprising a semirigid shell divided into a heel unit and a separate toe unit, which are slidingly associated, and a soft innerboot that can be accommodated in said shell, characterized in that it comprises means for detachable interconnection between said soft innerboot and an element for at least partial covering and/or fastening of said soft innerboot, said element being associated with said toe unit and protruding therefrom.
- Further characteristics and advantages of the invention will become better apparent from the detailed description of an embodiment of the sports shoe according to the present invention, illustrated by way of nonlimiting example in the accompanying drawings, wherein:
- Figure 1 is an exploded perspective view of an embodiment of the sports shoe according to the present invention;
- Figures 2 and 3 are two further partially exploded perspective views of the sports shoe shown in Figure 1.
-
- In the examples of embodiments that follow, individual characteristics, given in relation to specific examples, may actually be interchanged with other different characteristics that exist in other examples of embodiment.
- With reference to the figures, the
numeral 1 designates a sports shoe, such as for example a roller skate, with fourwheels 2 arranged in line. - Said
wheels 2 are associated, by way ofmechanical means 3 of a known type, with a supportingframe 4 whose transverse cross-section is arch-shaped, i.e. is like an inverted U. - In particular, the
wheels 2 are associated between the downward-pointing wings of theframe 4. - A box-like heel unit, designated by the
reference numeral 5, is associated above the rear portion of saidframe 4 and is open at the front and top. - At the front of the
heel unit 5, theframe 4 has, in an upward region,guides 6 for the longitudinal sliding of atoe unit 7, from the lower surface of which, not shown, an edge 7a protrudes laterally and frontally and is designed to contain the foot of the user. - The
toe unit 7 and theheel unit 5 constitute a shell, generally designated by thereference numeral 8, that is advantageously made of semirigid material and is adapted to contain asoft innerboot 9 for accommodating the foot of the user. - The
soft innerboot 9 can be associated with theheel unit 5 advantageously by further interlocking means. - For example, such interlocking means are associated laterally with the
soft innerboot 9, approximately to the rear of the malleolar region, and comprise at least a pair ofrigid cleats 10, only one of which is shown in the figures. - Said
cleats 10 can be arranged within complementarilyshaped openings 11 formed in theheel unit 5, so as to ensure mutual locking once the foot has been inserted in the skate. - The
sports shoe 1 further comprises detachable interconnection means, designated by thereference numeral 12, for interconnection between thesoft innerboot 9 and an element for the at least partial covering and/or fastening of saidsoft innerboot 9, such as for example a sheath orovershoe 13. - Said
overshoe 13 is associated with thetoe unit 7 at its front region and has two lateral flaps, respectively designated by thereference numerals toe unit 7 toward theheel unit 5. - As shown in Figure 3, said pair of
flaps soft innerboot 9 laterally, interposing itself partially between said innerboot and the sides of theheel unit 5. - The connection between the
overshoe 13 and thesoft innerboot 9 is achieved by way of said detachable interconnection means 12: in this particular embodiment, shown merely by way of example, saidmeans 12 are advantageously constituted by atongue 15 that protrudes from theinnerboot 9 approximately proximate to the toe region, can be arranged through aslot 16 formed transversely in theovershoe 13 and is provided with engagement means, designated by the reference numerals 17a and 17b, for engagement with saidsoft innerboot 9. - In particular, the engagement means 17a and 17b can be constituted advantageously for example by a press-stud.
- The
overshoe 13, moreover, can comprise fastening means for fastening theshoe 1 around the user's foot, such as forexample laces 18 guided between theflaps overshoe 13. - Operation of the sports shoe is therefore as follows: with reference to the figures, when the toe unit is moved forward, the overshoe is forced to follow such movement, thus applying to the soft innerboot a traction with a point of application located at the detachable interconnection means.
- In this manner, the elongation of the soft innerboot occurs before foot insertion and is not due to the insertion of the user's foot.
- It has thus been found that the invention has achieved the intended aim and objects, a size-adjustable sports shoe having been provided which allows the user to have at his disposal all the sizes planned during design.
- The sports shoe according to the invention, moreover, is very comfortable regardless of the preset size, since the soft innerboot is deformed by the necessary extent before foot insertion.
- Moreover, the overshoe preserves the soft innerboot from wear and any damage, since it covers the lower part of said innerboot, i.e., the part that is particularly subjected to contacts with the ground or with other objects.
- The sports shoe, finally, is very simple from the structural standpoint and therefore has low manufacturing costs.
- The invention is of course susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
- The materials used, as well as the dimensions that constitute the individual components of the invention, may be more pertinent according to specific requirements.
- Various means for performing functions as the ones required by the present invention and set forth in the illustrated preferred embodiment can be envisaged by those skilled in the art which are technically equivalent with those herein illustrated.
- The disclosures in Italian Patent Application No. TV2002A000153 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.
