Description

"Sports footwear for cycling use"
Technical field
The present invention relates to sports footwear for cycling use. of the type including a sole which comprises:
- a flexible element bearing a tread surface and an opposite second surface,
- the flexible element defining longitudinally opposed heel and toe regions between which there is an arch region.
- a plate-like element, stiffer than the flexible element and disposed next to the second surface,
- fixing means for an element for attachment to the pedal, the fixing means being associated with the platelike element and accessible from the tread surface.
Background art
In the. specific technical field there is footwear intended mainly for walking use and bearing a particularly flexible and comfortable sole, and footwear which is clearly suitable for cycling use and which bears a particularly rigid sole with fixing memoers for an element for rapid attachment to the pedal. An example of this second type of footwear is known from British patent No. 2,239,779. The footwear of this example has a sole with a flexible element which bears the tread surface and to which a stiffer plate-like element extending as a midsole is fixed by gluing. Next to the toe region, the midsole which constitutes the stifrening element of the footwear has a pair of parallel through-slots in which an attachment element for fixing the footwear to the pedal is engaged. The currently known footwear of the first type has no specific arrangement to facilitate the use of rapid attacnment pedals. It can tnerefore be used, for example, in off-road cycling, better known by the English term "mountain biking", exclusively with conventional, non-specialized pedals.
In contrast, although the footwear of the second type on the one hand permits use with rapid attachment pedals, on the other hand, it is too stiff to provide adequate comfort for walking. As a result, this type of footwear is therefore intended strictly for cycling use in which only occasional walking is envisaged.
The problem upon which the present invention is based is that of providing sports footwear which is designed structurally and functionally to permit walking with comfort comparable to that of a normal walking shoe whilst being functionally equivalent to the most rigorously designed cycling footwear.
Disclosure of invention
This problem is solved by the invention by means of sports footwear of the type indicated, characterized in that the plate-like element extends to cover the second surface only partially, in a region between the toe and arch regions.
Brief description of drawings
The characteristics and advantages of the invention will become clearer from the following detailed description of a preferred embodiment thereof described by way of non-limiting example with reference to the appended drawings, in which: - Figure 1 is a side elevational view or a sports shoe formed according to the present invention.
- Figure 2 is an exploded perspective view of the sole of tne shoe of Figure 1 from above.
- Figure 3 is a section taken on the line III-III of Figure
2,
- Figure 4 is a section taken on the line IV-IV of Figure 2,
- Figure 5 is an exploded, perspective view of the sole of Figure 2, from below,
- Figure 6 is a perspective view of a variant of a detail of Figure 2.
Modes for carrying out the invention
In the drawings, a sports shoe, indicated A, for cycling use with rapid attachment to the pedal, comprises an upper B of known type, and a sole C connected thereto. The sole C comprises a flexible element 1 bearing a tread surface 2 and an opposite second surface 3. Longitudinally opposed toe and heel regions 4, 5 are identified in the flexible element 1. Between these there is an arch region 6.
Two protective elements 7, 8 projecting from the surface 3 extend around the toe 4 and the heel 5, respectively.
The tread surface 2 has a recess 9 extending longitudinally in a region between the toe and arch regions 4 and 6 and flanked by two edge portions 10, 11. A plurality of pairs of V-shaped notches 12, between wnich arrow-shaped cleats 13 are defined, ls formed on each edσe portion 10, 11 as well as in the heel region 5. The notches 12 and the cleats 13 define a pattern for improving tne grip of the treac surface 2 on the ground. The surface 3 bears first and second blind cavities 14, 15, the former extending in the heel region 5 and partially in the arch region 6 and the latter between the arch region 6 and the toe 4. Both of these cavities bear mtersecting ribs 16 and are intended to be filled with expanded resin.
In tne cavity 15, the ribs 16 surround a recess 20 with concave wall 20a.
The recess 20 is formed in the second surface 3between the toe region 4 and the arch region 6. covering the latter only partially. The wall 20a has a central hole 21 extending througn the tread surface 2 where the hole faces the recess 9 .
The hole 21 is surrounded by a lip 25 projecting from the wail 20a and having two opposed gaps 26a,b.
The recess 20 constitutes a seat for housing a plate-like element 30 made of stiffer material than the flexible element 1. A concave surface 31 and a convex surface 32 are identified on the plate-like element 30 which has an egg-shaped periphery. The thickness of tne plate-like element 30 between the surfaces 31, 32 increases from its periphery towards its centre.
with the convex surface 32 housed, substantially with form coupling in the recess 20, the plate-like element 30 extends to cover the surface 3 in a region between the toe region 4 and the arch region 6, leaving the toe region 4 and part of the arch region 6 clear.
It should be noted that the stiffness of the plate-like element 30 decreases from its centre towards its periphery owing to its variable thickness. This reduces the difference in stiffness between the flexible element 1 and the plate-like element 30 in the peripheral region of the latter limiting the possibility or relative sIiding between the surface 32 and the wall 20a once they are glueo together. The plate-like element 30 is thicker centrally, however., wnere tne stresses due to the attacnment of the shoe to the pedal are concentrated.
The convex surface 32 has a central annular groove 35 for housing the lip 25 substantially with form coupling.
Two projections 36a,b are provided in the groove 35 for coupling with the corresponding gaps 26a,b. The groove 35 and the lip 25 constitute mechanical engagement means Detween the flexible element 1 and the plate-like element 30.
The convex surface 32 has parallel grooves 37 spaced apart and extending transverse the toe-heel axis. These grooves serve to improve adhesion between the wall 20a and the surface 32.
The concave surface 31 is shaped so as to connect continuously with the surface 3, maintaining substantially the same curvature as the surface 3 along its periphery. A rectangular seat 40 formed in the concave surface 31 has two parallel, spaced-apart slots 41a,b which are elongate in the toe-heel direction and extend through the plate-like element 30 so as to face the hole 21.
In a preferred embodiment, tne flexible element 1 is formed of elastomeric material such as synthetic rubber or the like, whereas the plate-like element 30 is made of polyamide resin f illed with graphite .
In order to fix the sole to an element for attachment to the pedal, not snown, a rectangular plate 55 is noused in tne seat 40. One side of the plate 55, whicn ls preferably made of metal, bears four identical pillars 51 engaged siidmgly in pairs in the corresponding slots 41a, 41b. Each pillar 51 has a threaded axial through-hole 52 whicn is accessible from tne tread surface 2 through the corresponding slot 41a.b. A cover 60 is provided for covering tne hole 21 at least partially on the tread surface 2.
The cover 60 comprises a rectangular plate-like body 61. One side of the body 61 bears four identical, parallel and spaced-apart appendages 62, as well as two pins 63. The positions of the frustoconical hollow appendages 62 are such that they can be engaged removably under pressure in the correspondmg holes 52 in the plate 55. The pins 63 are provided for interfering with the corresponding slot 41a. 41b and preventing the plate 55 from sliding relative to the plate-like element 30.
As an alternative to the cover 60 of Figure 1, a second cover 160 shown in Figure 5 may be used. The cover 160 comprises a plate-like body 161 bearing a projection 166 on one face. Two holes 162a,b formed in the projection 166 extend through the body 161 so that the cover 160 can be fixed to the plate 55 by means of screws engaged in the holes 162a. 162b and screwed into corresponding holes 52.
The covers 60, 160 are preferably made of material similar or identical to that of the plate-like element 30.
The invention thus solves the problem set, achieving many advantages. In particular, the sports shoe produced has a sole with differentiated stiffness in which there is greater stiffness in the region intended for attachment to the pedal during cycling use and, at the same time, the walking flexibility and comfort of the shoe are unchanged.
