Description

The present invention relates to a shoe assembly with exchangeable sole portions. More particularly, the present invention relates to a shoe assembly having a shoe and exchangeable sole portions which have mounting projections adapted to fit into attachment holes and are arranged in various shapes and designs for multiple styles, allowing said soleing portions to be added to ballerina-style flat shoes without heels, which are comfortable and commonly sold on the market but which nevertheless are suitable for only one style and which have a flat, beadless structure without the possibility of change, in that said protrusions penetrate into said attachment holes drilled on two support points, one of which is in front of the shoe and the other is partly rear. Problems that most women, especially women working in offices and indoor spaces of this type, encounter with regard to shoes are those of trying to find a suitable shoe for their styles, not having the opportunity to make changes to a heel model of the desired shoe as well as to have comfort, and when they wish to have comfort and be chic the same day, to have to carry additional shoes and to change shoes in order to reach the goal and to have to buy lots of shoes for all these.

The present invention aims to solve these problems and achieve this goal by allowing women to have both comfort and chic style in one and the same product whenever they want using only one sole and thanks to suitable exchangeable base parts, by suitable mounting methods, on this sole. The present invention allows basic features of flat sole, soled wedge and platform heel sole structures suitable only for styling and directing female users to purchase separate shoes according to their preferences. comfort or style, to be joined together by appropriate methods and to have the opportunity to change these characteristics of the sole structure. In this way, the present invention enables female users to save money because they no longer have the obligation to buy more than one pair of shoes. The present invention, with the advantages of having multiple soleing parts and different models and types within these soleing parts, allows the wearer to use both shoes without heels, shoes without heels and platform-heeled or wedge-heeled shoes by inserting the protrusions of the appropriate sole portion into the attachment holes on the front and back of the soleplate, possibly after bleeding the plugs of the fixing hole, according to the preference of the user. The user having a flat shoe without heel, a short shoe or a wedge heel, with an introduction-extraction process requiring only a few seconds, will have increased comfort since it will not have to carry with she's extra shoes and will save money by having all these products put together in one set. The subject of the present invention is therefore a shoe assembly enabling an exchange of soleing parts, comprising a boot formed of a upper and a sole attached to the upper, characterized in that the sole on its outer surface presents in its parts respectively front and rear a removable attachment hole of a projection of a forming part forming front platform, heel or wedge heel.

The shoe assembly may further comprise, in the first and second embodiments of the present invention, a front platform forming portion and / or a heel forming portion, each having a first ground engaging surface and opposed to said first surface, a second surface from which extends a protrusion detachably attachable in the fastening hole at the front of the sole assembly for the front platform forming portion and the fastening hole therein. rear portion of the sole assembly for the heeling portion forming heel. In the first embodiment of the present invention, the projection of the front platform forming portion and / or the projection of the heel forming portion is threaded for threaded fastening into the corresponding threaded fastening hole. In the second and third embodiments of the present invention, the shoe assembly may further comprise a wedge heel portion having a first ground contact surface and, opposite said first surface, a second surface from of which extend, in its parts respectively front and rear, a projection adapted to be removably attached in the fixing hole respectively in the front portion and in the rear portion of the sole. In the second embodiment of the present invention, the protrusion of the front platform forming portion and / or the projection of the heel forming portion and / or the projections of the wedge forming portion are capable of being releasably secured by interlocking in the corresponding fixing hole. In the third embodiment of the present invention, the wedge heel portion comprises, for each protrusion, a passage opening at a first end into the peripheral surface of the protrusion and at a second end into the lateral surface of the portion. wedge-shaped sole assembly, and an insert mounted in the passageway so as to be movable between a first position in which a first and a second portion of the insert project out of the first end and the second end of the passage respectively, and a second position in which the first portion of the insert does not extend out of the first end of the passage. The soleing may comprise a shank metal plate 10 and also extending into the respective front and rear portions of the sole. The shoe assembly may further include two plugs each adapted to plug a fastening hole, to allow a user to walk with the shoe without attaching a sole portion forming front platform, heel or wedge heel. The rod may be made of an elastic material so as to maintain the foot of the user.
