Description

SPORT SHOE WITH A MOVABLE INSERT LOCATED INSIDE THE SQLE AND SUITABLE FOR CHANGING THE FEATURES OF THE LATTER WHEN IT HITS THE GROUND
The present invention relates to a sports shoe in accordance with the introduction to claim 1.
A sports shoe is known to comprise a sole for contacting the ground and, above said sole, a vamp for receiving the foot of a user wearing the shoe. The sole comprises an outer part, an inner part and, overlying this latter, an innersole with which the user's foot makes contact. The sole outer part comprises two separate portions: a metatarsal front first portion and a rear second portion (located at the heel). These portions, which contact the ground during normal shoe use, are separated by an intermediate third portion positioned at the arch of the user's foot and separated from the ground.
The sole is usually made of EVA or similar materials. Solutions are known in which the sports shoe is provided with elements which return to the user a part of the energy discharged thereby onto the ground during movement. These shoes are however aimed only at a single particular use (competitive or non-competitive sports) during which the user
or athlete receives said energy while moving.
An object of the present invention is to provide a shoe which is improved
compared with known shoes. A particular object of the invention is to provide a shoe offering optimal use to the user whether pursuing a sporting activity or merely running on the ground without pursuing any specific activity.
Another object is to provide a shoe of the stated type which is simple to use whether the user wears it to pursue a sporting activity or is merely running or walking on the ground.
A further object is to provide a shoe of the stated type which is reliable in use and is of a cost comparable with known sports shoes. These and other objects which will be apparent to the expert of the art are attained by a shoe in accordance with the accompanying claims. The present invention will be more apparent from the accompanying drawings, which are provided by way of non-limiting example and in which: Figure 1 is a schematic longitudinal section through a shoe, of the invention shown at one stage of its use; Figure 2 is a view of the shoe of Figure 1 from below; Figure 3 is a view similar to that of Figure 1 , but with the shoe shown at a different stage of its use;
Figure 4 is a view of the shoe of Figure 3 from below; Figure 5 is a partial schematic view of a part inside the sole of Figure 1 ; and Figures from 6 to 8 are schematic longitudinal sections through the part of Figure 5 in different utilization positions.
With reference to said figures, a shoe of the invention is indicated overall by 1. It comprises a sole 2 and an overlying vamp 3 to contain the user's foot. The sole 2 comprises an outer part 4 for contacting the ground, an inner part 5 and an innersole 6, this latter contacting the user's foot. The outer part 4 comprises a first front (metatarsal) portion 8 and a second rear portion 9 (located at the heel) separated by an intermediate portion 10; the intermediate portion 10 is raised from the ground on which the portions 8 and 9 rest.
In the interior of the inner part 5 of the sole 2 a movable insert 15 of rigid material is disposed, able to assume two stable working positions, alternative to each other, inside said part 5 of the sole 2. Specifically, in a first working position (Figures 3 and 4) said insert is disposed at the front portion 8 of the sole 2, whereas in the second working position (Figures 1 and 2) the insert lies substantially in correspondence with the third portion 10 of the sole 2 to also involve the second portion thereof. More in particular, the insert 15 presents a body 16 having a flat portion 17 for sliding within a corridor 18 of an element 19 inserted into the interior of the sole 5, mainly in correspondence with the portion 8 although it also involves the sole portions 9 and 10. Said flat portion 17 terminates substantially with two overlying arms 21 , 22 which are movable relative to each other and mutually elastic. The arm 21 rises inclinedly from the portion 17 and overlies the arm 22; the arm 21 comprises a step 25 cooperating with a tooth 26 of a portion 27 of the element 19 defining the access to the corridor 18. At said portion 27 said corridor widens to be able to receive the arm 21 when the portion 17 is inserted into the element 19 by sliding the body 16 along a flat portion 28 of the element 19 which extends from said
corridor. The tooth 26 cooperates with the step 25 when the portion 21 penetrates into the corridor 18 in order to lock the insert 15 in a position in which the portion 17 is inserted into the corridor 18.
This insertion is achieved by moving the insert 15 along said flat portion 28 (arrow F of Figure 4 and arrow K of Figure 7), said insert being retained within the element 19 even when (partly) external to the element 19. The corridor 18 is present in the portion 8, the flat base 28 being positioned between the portions 10 and 9.
To enable the insert 15 to move, the arm 21 presents a projection 31 accessible by the user from below the shoe: his projection projects from a window or aperture 33 provided in the portions 9 and 10 of the outer part 4 of the sole. By acting on the projection 31 of the insert 15 this latter can be moved along the flat base 28 and be brought into a position such that its portion 17 is inserted or not inserted into the corridor 18. By moving said portion 17 inside said corridor 18, the insert 15 reaches the position shown in Figure 4 to hence stiffen the front part of the sole and offer support to the user when undertaking a sporting activity such as
spinning.
In contrast, by acting on the projection 31 by pressing it towards the underlying arm 22 (arrow M of Figure 6), the portion 17 can be brought into correspondence with the portion 27 of the element 19, the insert 15 becoming partly extracted from this latter (arrow W of Figure 2) to lie mostly within the sole portion 10 and give the shoe optimal rigidity for its use during
normal running.
Obviously, the element 19 is formed such that the insert 15 is unable to completely escape from it. For example, the element 19 presents opposing lateral edges 19A such that it overlies the insert 15 (or rather the opposing sides of the portion 17 and the sides of the arm 22) whatever the position reached by this latter within the sole.
At least the insert 15 is made of a rigid material and preferably of a composite material such as carbon fibre, glass fibre, aramid fibre or a combination of these fibres.
The shoe of the invention can be produced by methods known to the expert of the art: for example the element 19 provided with the insert 15 can be inserted into the mould in which the sole is moulded before injecting its constituent material therein.
A particular embodiment of the invention has been described; it can however be obtained in different embodiment such as one in which the insert 15 is made slidable in the inner part 5 of the sole 2, within a seat or chamber formed directly in this latter, or an embodiment in which the seat or chamber for sliding the insert 15 is made in a body provided in the part 5 of the sole 2, said body having characteristics such as not to deform as a result of the movement of the insert therein, and achieving recovery of the energy transferred by the user to the ground during use of the shoe. This insert, defining a device positioned within the sole of a shoe and arranged to selectively stiffen of this latter, also independently forms a subject of the invention as defined by the accompanying claims. This device can assume different positions in the sole along the central longitudinal axis thereof to stiffen the metatarsal part, the arch or the heel, or to the side of this axis to stiffen the sole along a lateral part thereof.
