    DESCRIPTION
    Object of the Invention
    The present invention relates to a system for manufacturing footwear by assembling components, which provides essential novelty characteristics and notable advantages over the means known and used for the same purposes in the current state of the art.
    More in particular, the invention develops a system whereby it is possible to manufacture footwear from previously manufactured and precisely adjusted components, where the component assembly operation is carried out by coupling between complementary elements such as studs, pivots or protuberances carried by some of the components and insert holes carried by the complementary components, or through the provision of guidance zones, so that the assembly can be carried out by any person without risk of making mistakes, and with the security of obtaining finished shoes or shoes with a perfect level of finish. The system also admits the possibility of combining various components to obtain shoes or footwear with variable aspects.
    The scope of the present invention is within the industrial sector dedicated to the manufacture of footwear in general.
    Background of the Invention
    It is a known fact that the manufacture of footwear

    It involves a set of manual operations performed by the operators in charge of assembly. As will be understood, the manual nature of these operations requires that, in addition to the quality of the components used to manufacture the shoe, the operators in charge of the assembly operations are skilled persons so that it can be guaranteed, up to a certain limit, that mounting errors are not going to be made and that the level of finishing is going to be above an acceptable limit, especially if one takes into account that the assembly of some of the components requires manual sanding, gluing or nailing operations . Obviously, apart from the requirement of care and attention that must be given by the assembly workers to achieve the desired level of finish in the final shoe, this form of work is laborious, requires time and specialized labor, with the consequent impact of all this in the manufacturing costs and in the final price of the finished footwear.
    There is therefore a need in the current state of the art to simplify shoe assembly operations in order to reduce production costs, while guaranteeing at all times the quality and level of finishing and presentation of the final product.
    Summary of the Invention
    Taking into account the drawbacks of the prior art mentioned above in relation to the manufacture of footwear, the present invention has developed an advantageous system with which an important part of the aforementioned problem is solved. For this, the system of the invention has provided the manufacturing of the different components that make up a shoe as separate pieces, of injected thermoplastic material with the optional possibility of integrating some part of fiber or

    metal as a function of the desired characteristics for the final product, all these components having respective integral elements designed in a mutually complementary manner to allow the adjacent components to be coupled together. Taking into account that the manufacturing of each of the components is carried out with CNC-type machines (numerical control), it will be understood that the precision of each component is optimal, thereby achieving a high quality final design and finishing shoe . In addition, since all components are previously dimensionally adjusted, manual assembly operations are simply limited to the coupling of components, which reduces assembly times, eventually no specialization of labor is necessary, and the costs of manufacturing decrease significantly.
    According to the system proposed by the invention, a shoe constructed by said system comprises from a generic point of view the usual components of any conventional shoe or footwear: cut, sole, sole and heel, but unlike conventional shoes, the System of the invention provides that the assembly of the various components of the shoe is carried out by coupling of protruding elements such as lugs, pivots or protuberances of another type, carried by at least one of the components, in housings or openings carried by the adjacent component and specifically designed to receive such protruding elements of the first component. By way of illustrative and non-limiting example, a preferred embodiment may consist of the provision of a properly sized plant component, which includes a multiplicity of blind holes located next to the perimeter edge of the plant, accessible from the surface

    lower of the same, of pre-established dimensions, and one or more protruding lugs also with respect to the lower surface of the plant, located at the rear of the same, that is, in the area correspondingly facing the heel of the footwear (if wearing ). On the other hand, the component corresponding to the sole of the footwear presents a multiplicity of outstanding elements of the type mentioned, in corresponding positions with the housings of the floor, and dimensionally adapted to the mentioned housings, in such a way that the coupling between both components ( plant and sole) can be carried by insertion by pressing the protruding elements of the sole into the holes or housings of the plant. In addition, in relation to the rear part, the sole also has protruding formations of the same type mentioned for coupling to the heel component, which carries a multiplicity of housings prepared to receive the corresponding outstanding formations of the sole. Additionally, the heel includes one or more blind holes extended according to the longitudinal direction of the heel from its upper base, intended to receive the one or more protruding elements from the rear of the plant. Finally, the lower tip of the heel also includes one or more holes for receiving as many protuberant portions incorporated by a conventional lid element.
    As will be understood, the operation of manufacturing a shoe or footwear with its previously adjusted components in the manner indicated, is easy and quick to carry out, with the consequent reduction of operating costs and avoiding at the same time the possibility of produce human errors as in conventional assembly.

    As stated, the linkage and
    solidarity between the components of the footwear is by coupling protuberant portions carried by one or more of the components in specific housings carried by other components. If desired, this assembly phase can be accompanied by some immobilization operation such as by screwing or with the application of some type of glue or glue that provides additional immobilization between the components of the footwear, once mounted.
    In an alternative form of implementation of the system of the invention, the protruding elements and the holes or housings for the reception thereof, can be replaced by coupling guides in any of the components (for example, in the sole and heel components ), and emerging portions in the complementary components, that is, surface recesses in said sole and heel components and an emerging projection
    from the bottom facing surface of the plant component, of dimensions consistent with the recessed areas
    complementary. The final bonding, in this alternative embodiment, is carried out by means of an operation of gluing or screwing the components.
    Brief Description of the Drawings
    These and other features and advantages of the
    The invention will become more clearly apparent from the following detailed description of a preferred embodiment thereof, given only by way of illustrative example and without limitation whatsoever with reference to the accompanying drawings, in which:
    Figure 1 is a schematic view, in side elevation, showing an exploded view of the components that

    they integrate a heel shoe, the coupling and mounting means being visible between components proposed by the system of the invention;
    Figure 2 is a schematic bottom plan view of an example of a floor component for the footwear of Figure 1, according to the invention, and
    Figure 3 is a schematic illustration of an alternative embodiment of the system of the invention.
    Description of the Preferred Embodiment
    As mentioned above, the
    Detailed description of the preferred embodiment of the object of the invention will be carried out in the following with the help of the attached drawings, through which the same numerical references are used to designate the same or similar parts. Thus, attending first to Figure 1 of the drawings, a view of an exploded heel shoe can be seen, with the different components separated for a better
    visualization of them. As is conventional, a shoe constructed in accordance with the system of the present invention, comprises, as in shoes
    conventional, a component 1 constituting the cut of the shoe, a component 2 or plant intended to provide the support surface for the user's foot, a sole component 3 of the shoe, possibly a
    constituent component 4 of the heel of the shoe, and a cover 5 associated with the heel 4. As said, the components of the shoe, preferably manufactured in an injected thermoplastic material, with the possibility of integrating some part of fiber or metal depending on the desired characteristics for the final product, respond to a design that allows the various components

    they can be linked together by mutual coupling of the complementary elements they incorporate. Thus, the floor 2 is of conventional configuration, and has a multiplicity of housings constituted by blind holes 2a, opened outwards by the face of the floor 2 destined to occupy the lower position, performed in the molding operation of the plant itself in the vicinity of the perimeter edge, in parallel with said edge and extended to almost the entire perimeter, with the exception of the heel area. This design of the floor 2 can be seen more clearly in the representation of Figure 2. Additionally, the floor 2 incorporates, in the heel area, at least one protruding element, such as a stud or other protuberance, marked with the numerical reference 2b. As shown in the representation of Figure 2, the plant 2 includes in the present embodiment two studs 2b transversely aligned with each other in the vicinity of the rear end, but this number of studs may be larger or smaller, varying according to each need. or concrete convenience.
    The sole 3 follows a development as is conventional for some heel shoe designs of the prior art. Thus, most of the surface of this component is designed for its complementary coupling with the floor 2, and also integrates a rear portion 3b that adopts an approximately vertical positioning, and which is intended to engage with the heel 4 of the shoe. The particularity of the sole component 3 of the shoe is that it incorporates a multiplicity of protuberant formations 3a, such as lugs or other protuberant formations, distributed along the perimeter edge of the piece, in positions correspondingly coinciding with the blind trades 2a
    5

    of the floor 2, and sized in accordance with the mentioned housings so that they can be embedded inside the holes simply by pressure when the floor 2 and the sole 3 are coupled together. In addition, the rear portion 3b of the sole includes a number of these same protuberant formations 3a, in predetermined positions and coinciding with blind holes 4a made in the front face of the heel 4, also sized in accordance with the protrusions 3a for coupling between the heel 4 and sole 3.
    Also for coupling purposes, the heel 4 incorporates a blind hole 4b at its upper base, extended according to the longitudinal direction (in height) of the heel 4, and adapted to receive and retain the stud 2b that projects downward from the area of heel of the floor 2.
    The above description shows a set of practical advantages related to the assembly operations of the shoe shown in Figure 1 of the drawings. As will be understood, it is sufficient to perform the coupling operations between the heel components 4 and sole 3 and then the coupling of both with the floor 2, by fitting the various protuberant formations of some of the components in the holes or housings of the other components, being operations that are free of error (they only have a possibility of coupling) and are also achievable in very short periods of time, with the consequent savings already mentioned. The cut 1 of the footwear can be joined to the rest of the components by some conventional technique.
    Finally, to finish off the assembly of the set,
    5
    10
    fifteen

    25

    35
    simply attach the cover 5 to the heel 4. Split it, in the same way as in the case of the components already described, the heel 4 includes one or more blind holes 4c accessible from the bottom base of the heel and extended according to the longitudinal direction (in height) of the heel 4, while the cover 5 includes a number of protruding studs or formations 5a equal to the number of holes 4c of the heel.
    As said, the coupling between the various components of the shoe is done simply by pressing against each other once placed in correct relative positions. If desired, to establish greater solidarity between components, some type of adhesive or screw system can be used to join the components together.
    Continuing with the description, reference is now made to the illustration of Figure 3, in which it appears, as has been said, a representation of an alternative embodiment of the footwear manufacturing system of the present invention.
    As can be seen, Figure 3 shows an exploded schematic representation of the 2 'floor components, 3' sole and 4 'heel for footwear, conceived in accordance with an alternative version of the system of the present invention. Unlike with the same components of the embodiment shown in Figure 1, the floor 2 'includes an emerging portion 7, projected from its lower base, of predetermined height, which results in the formation of a stepped area extended perimetrically in parallel with The edge of the piece. In addition, the sole 3 'and the heel 4' include a respective surface recess 6, 6 ', sized in
    5
    10
    fifteen
    twenty
    25
    30
    concordance with the emergent portion 7 of the plant 2 ', so that the union between the components is carried out simply by guided coupling between the emergent portion 7 of the plant and the surface recesses 6, 6'
    of the sole and heel. That way, once the components are mutually coupled, the footwear will be left
    fully formed, without this being possible in this case there may be mounting errors. The definitive bonding between the various components can be carried out eventually with the help of an adhesive or screwing means, and the heel 4 'includes a blind hole 4'c in its lower base to receive the protruding portion 5'a of a 5 'cap, as conventional.
    It is not considered necessary to make the content of the present description more extensive so that a person skilled in the art can understand its scope and the advantages derived therefrom, as well as carry out the practical realization of its object.
    Notwithstanding the foregoing, and since the description given corresponds only to an example of
    preferred embodiment of the invention, it will be understood that within its essentiality multiple variations of detail may be introduced, also protected, which may affect the shape, size or manufacturing materials of the assembly or its parts, without implying any alteration of the invention as a whole, delimited only by the claims provided below.
