Description

DESCRIPTION

Modular footwear

TECHNICAL SECTOR

The present application refers to a type of modular, multipurpose footwear, which is easily and quickly configurable to be able to carry out different activities, mainly sports.

STATE OF THE ART

The use of different pieces of footwear for different activities is known in the state of the art: skating, sports ... Each piece of footwear requires a series of modifications, mainly in the sole, such as the addition of wheels.

It is also known in the state of the art, mainly as children's footwear, to use shoes that have a wheel on the heel, partially hidden, so that the user can skate on their heels, or walk in a normal way.

If a user wants to do multiple activities, they need two different pieces of footwear for each activity. This requires a very large space (especially in the case of skates) and creates problems in terms of the real possibility of carrying out these activities.

The applicant does not know of any footwear that can solve these problems.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a versatile, modular footwear, according to the first claim. Its different variants solve the problems outlined.

It is a modular footwear, with a replaceable sole to perform different activities. It comprises an upper part with the upper, the toe, the heel and a base under the sole of the foot in addition to the sole. This sole is removably attached from the top by a series of compatible male protrusions and female holes and by a retention system of the male protrusions within the holes. This is how the sole is interchangeable.

For example, the sole may comprise skating wheels or blades, diving fins, bicycle attachments, or any other type of custom modification of sports shoes.

The preferred restraint system comprises a cable take-up pulley such that take-up of the cable modifies the shape or position of the male protrusions or holes.

Other variants can be seen in the rest of the report.

DESCRIPTION OF THE FIGURES

For a better understanding of the invention, the following figures are included.

Figure 1: Side view of a first embodiment of the modular footwear.

Figure 2: Different models of sole: footwear with in-line wheels (A), footwear with parallel wheels (B) and footwear with fins (C).

MODES OF EMBODIMENT OF THE INVENTION

An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.

The footwear shown in figure 1 comprises an upper part (1) that includes the upper, the laces, velcro (registered trademark) or the like, the heel and the toe. The upper part (1) comprises a base (2) where a sole (3) is removably connected, for example by a series of compatible male projections (4) and female holes (5) forming a tongue and groove. In figure 1 the male projections (4) are arranged in the upper part (1) and the holes (5) in the sole (3).

A retention system (6) deforms the male projections (4) or the holes _{(5) to ensure that the sole (3) is perfectly fixed to the} upper part (1). The retention system (6) is preferably on the sole (3) to make replacement easier. For example, it can be a pulley (61) that collects a cable (62). The cable (62) deforms the sole (3) so that the fixation between the male projections (4) and the holes (5) occurs. For example, the holes (5) may be in a movable part within the sole (3) against a spring, so that when pulling r the cable (62) the spring is defeated and the sole (3) is secured to the top (1). The part may need to be moved to release or to fix the two parts.

_{Figure 2 shows several models of sole (3), with in-line wheels} (figure 2A), with parallel wheels (figure 2B), with wings (figure 2C). Figure 1 shows a sports sole (3), which can have a different design for tennis, bicycle, football, racing ... It can also have ice skating blades, etc.

Likewise, the sole (3) can be varied to modify the color of the footwear, to renew worn parts, etc.

Claims (1)
