FR2869768A1 - Shoe for sports and festival occasion, has sole on which fixed heel is integrated, removable heel with outer end sliding in cavity of fixed heel, and open and rotating ring placed around fixed heel to avoid dislocation of heels - Google Patents

Abstract

The shoe has a sole on which a fixed circular heel, having reduced thickness, is integrated. A removable heel has an outer end of shape similar to a cavity (3) of the fixed heel, where the outer end of the removable heel slides in the cavity. An open and rotating ring (4) placed around the fixed heel permits to lock the shoe to avoid dislocation of the heels. Lower and upper edges (5, 6) are provided for holding the ring.

Description

2869768 1

  The present invention relates to the device for adding on the same shoe is a flat heel or a high heel.

  Traditionally, the user opts for the purchase of a pair of flat shoes (small heel) or for a pair of high-heeled shoes. Depending on the desired use, sports walk or festive occasion, she must choose a type of shoe. Some solutions such as a single double-position heel could be considered. However, for greater strength, for greater safety and greater flexibility (all types of heel allowed), a disjunction of the heel of the shoe is necessary. To the technical problem, how to add on the same shoe is a flat heel or a high heel, several patents for interchangeable heels have already been filed: screw heels, fixing wedge, magnetization system, clips, pistons. All these technical solutions have the disadvantage of either a complexity of manufacture when the fastening system is in the heel itself or a lack of simplicity for the user when changing the heel.

  I propose the following technical solution: The device comprises according to a first feature a heel shoe integrated with the sole. This integrated heel is designed to receive, by an interlocking system, another heel of any height and shape. This thin heel, integrated, serves as support.

  The second feature is the locking system located on this heel so that there is no dislocation between the heel integrated to the sole and the heel added during walking.

  According to particular embodiments: The sole of the shoe may be rigid at the heel, flexible in the middle and rigid at its end.

  The thin heel built into the sole can be circular. It may have a T-shaped cavity. An open and rotatable ring around the integrated bead may be the locking mode.

  The removable heel may have on its top a rail, of shape and size corresponding to the shape of the cavity (for example, T), so as to slide therein.

  The accompanying drawings illustrate the invention: FIG. 1 represents the concept of the shoe with its thin heel integral with its sole.

  Figure 2 shows the integrated heel alone.

  Figure 3 shows a bottom view of the integrated heel alone.

  Figure 4 shows the shoe with a removable bottom heel. Figure 5 shows the back of a removable bottom heel. Figure 6 shows a 3/4 view of a removable bottom heel. Figure 7 shows the back of a removable high heel.

  With reference to these drawings, the device comprises a shoe whose integrated thin heel (1) is circular in shape, fixed to the sole (2) (Figure 1 plate 1). The sole has no cavity relative to the integrated heel.

  The thin heel built into the sole includes (fig.2): - a central part with four small recesses on its sides. In the central part there is only a T-shaped cavity (3).

  - A ring (4) open and rotating, which includes the central portion. two small borders - lower (5) and upper (6) which hold the ring.

  The T-shaped cavity (3) in the central portion extends to 3/4 of the heel (Figure 3). This cavity (3) allows the introduction by sliding back in front of the shoe, an independent heel surmounted by a rail (8).

  The ring (4) open and rotating serves as a lock: turning it, so that its opening is on the inside of the heel, it avoids a dislocation of the removable heel added. Its opening can not be greater than or equal to the diameter of the base of the heel. The ring (4) has at the bottom of its opening two small notches (7). The central part of the integrated heel has in its rear two small recesses (for an open position). It also has two other small recesses located opposite to the inside of the heel (for a closed position). Thus the user by a simple rotary movement will wedge the ring (4) by bringing the small notches (7) on the small recesses: for an open position or for a closed position.

  2869768 3 Two small curbs - lower (5) and upper (6) hold the ring (4) without preventing it from turning on itself (they prevent it from falling).

  According to board 2 and 3: The removable heel consists of a single block comprises: - a rail (8) a stop (9) - a heel (10) or (11) The rail (8) is of the same size and same shape as the cavity Io (3) so that the user can slide the removable heel in the integrated heel (1) to the sole (2) by a gesture back to the front of the front shoe Lock the assembly by turning the ring (4).

  A stop (9) allows the connection of the lower edge (5) on which the ring (4) rotates. This stop (9) will be of the same height and the same curved shape as the lower edge (5).

  A heel of any shape (10) or (11) covers at its base the entire integrated heel (1) to the sole (2).

  In the factory manufacture of the rail block - heel stop, the shape and height of the heel (10) (11) are chosen. Thus the user goes through a simple change of block, a low shoe to a high shoe, a square heel to a round heel ... an infinity of choices with the same technical process is possible. All types of removable heel can thus be nested on this shoe in a simple process (both in terms of its manufacture and its practical operation for its user), fast and safe.

  This process will be particularly appreciated in the shoe trade by its aesthetic side: heels shapes, colors and different heights and its practical side: heels to slip into his purse.
