Abstract
Proposed is a utility model relating to an improvement to a shoe, generally for women, which differs from conventional shoes in that the heel can be connected to and disconnected from the sole by screwing and is thus interchangeable. The present improvement comprises an insert (I) in the sole, having a threaded hole for receiving the centre screw (1) of the heel (S), said insert (I) also having a central opening, inside which a flexible tongue (L) is formed, the end of which is provided with a lower protuberance (R) which slots into a cavity (K) in the heel, said cavity (K) being disposed radially relative to the centre screw (1) of the heel (S) so that when the heel (S) is connected to the sole, the protuberance (R) remains engaged in said cavity (K), preventing rotation between the heel and the sole, and when the heel is to be disconnected, it is sufficient for the user to press on the underside of the tongue (L) (the underside of the shoe), thus disengaging the protuberance (R) from the cavity (K) of the heel (S) and making it possible to rotate the heel (S) and disconnect it from the sole.
Description
APERFEIÇOAMENTO INTRODUZIDO EM CALÇADO COM SALTO INTERCAMBIA VEL IMPROVEMENT INTRODUCED IN INTERCAMBIA VEL HEEL FOOTWEAR
[001] Campo da Invenção [001] Field of the Invention
[002] O presente modelo de utilidade se refere a um aperfeiçoamento introduzido num sapato - geralmente feminino - que se diferencia dos sapatos convencionais pelo fato de que o seu salto pode ser acoplado e desacoplado do solado por meio de aparafusamento, tornando-o assim intercambiável. Sendo que, o presente aperfeiçoamento propõe meios consideravelmente práticos para realizar o travamento/destravamento da rotação do referido salto no solado (parafuso). [002] The present utility model refers to an improvement introduced in a shoe - generally female - which differs from conventional shoes in that its heel can be attached and uncoupled from the sole by bolting, thus making it interchangeable. . Therefore, the present improvement proposes considerably practical means for locking / unlocking the rotation of said heel in the sole (screw).
[003] Estado da técnica State of the art
[004] Já são conhecidos alguns modelos de sapatos - geralmente femininos - os quais se destacam entre os demais por permitir a remoção do seu salto, possibilitando assim a sua transformação de um calçado de salto alto numa sapatilha, numa rasteirinha ou mesmo num sapato de boneca, dependendo do tipo do referido calçado, assim como a sua reversão com a recolocação do salto. Deste modo, um calçado do tipo scarpin, com a retirada do salto pode ser comutado para um calçado tipo sapatilha, ao passo que um calçado tipo sandália, com a retirada do salto alto pode ser comutado para uma rasteirinha e vice- versa. Sendo que, estes sapatos consistem essencialmente de um calçado feminino com salto, o qual detém na sua face superior a fixação de um parafuso verticalizado. Enquanto que, no solado é incorporada uma alma de aço (esquino), a qual é dotada de uma furação roscada - ou recurso equivalente - na qual o parafuso no salto é atarraxado ao ser o mesmo rotacionado, proporcionando assim o acoplamento entre salto e palmilha, ou num movimento contrário, o desatarraxamento e consequente desacoplamento. No entanto, ao ser atarraxado no solado, o salto fica ali fixado por meio de um único parafuso central, o que implica na ocorrência de desatarraxamentos involuntários durante o uso, já que ao andar, a somatória de
pequenos giros de pé que a usuária realiza, acaba por fazer com que o solado rotacione sobre o salto, causando o desatarraxamento progressivo, até cair completamente, separando-se o salto do solado. Sabe-se que o Certificado de Adição CA 132016009912-8 propõe a incorporação de um segundo parafuso disposto radialmente ao parafuso principal, e que tem como função travar a rotação do salto, porém, pela natureza do próprio parafuso, esta tarefa se torna pouco prática, e necessitando até mesmo de alguma ferramenta para o aperto do referido parafuso, evitando o seu desatarraxamento involuntário. There are already known some models of shoes - generally female - which stand out among the others for allowing the removal of your heel, thus enabling the transformation of a high-heeled shoes into a sneaker, flat or even a shoe. doll, depending on the type of footwear, as well as its reversal with the replacement of the heel. In this way a scarpin-like shoe with the heel withdrawal can be switched to a sneaker-type footwear, whereas a sandal-like shoe with the heel off can be switched to a flat foot and vice versa. These shoes consist essentially of women's heeled shoes, which have a vertical bolt on their upper face. While a steel core (corner) is incorporated in the sole, which is provided with a threaded hole - or equivalent feature - in which the bolt in the heel is screwed while being rotated, thus providing coupling between heel and insole. , or in a reverse movement, the detachment and consequent decoupling. However, when it is screwed to the sole, the heel is fixed there by means of a single central screw, which implies the occurrence of involuntary loosening during use, since when walking, the sum of small turns of the foot that the user performs, ends up causing the sole to rotate over the heel, causing the progressive detachment, until it falls completely, separating the heel from the sole. It is known that Certificate of Addition CA 132016009912-8 proposes the incorporation of a second radially disposed screw into the main screw, which has the function of locking the rotation of the jump, however, due to the nature of the screw itself, this task becomes impractical. , and even needing some tool for tightening said screw, preventing its unintentional unscrewing.
[005] Objetivos da invenção Objectives of the invention
[006] Com o objetivo de solucionar tais inconvenientes foi que se desenvolveu o presente modelo de utilidade, o qual compreende um inserto ao solado, e que detém o orifício roscado para o atarraxamento do parafuso central do salto - orifício este que pode ser proporcionado por uma porca flanjeada, um inserto redondo (com um único ou vários diâmetros na mesma peça), com rosca central, ou até mesmo uma alma metálica com um furo roscado - E sendo que o referido inserto também apresenta uma abertura central, no interior da qual é formada uma lingueta flexível, a qual é dotada de um ressalto inferior na sua extremidade, o qual encaixa no interior de uma cavidade no salto, sendo esta cavidade disposta radialmente ao parafuso central do salto, de modo que assim, enquanto o salto se encontra acoplado ao solado, aquele ressalto se mantém encaixado no interior daquela cavidade, travando contra o rotacionamento entre salto e solado, e por ocasião do desacoplamento do salto, basta que o usuário pressione a face inferior da lingueta (na face inferior do sapato), desencaixando assim o ressalto do interior da cavidade do salto, e então, podendo rotacionar o salto e desacoplá- lo do solado. In order to remedy such drawbacks, the present utility model has been developed which comprises a sole insert and holds the threaded hole for tapping the center bolt of the heel - which hole can be provided by a flare nut, a round insert (single or multiple diameters in the same piece) with a central thread, or even a metal core with a threaded hole - and said insert also has a central opening within which a flexible tongue is formed which is provided with a lower shoulder at its end which fits within a cavity in the heel, which cavity is arranged radially to the central bolt of the heel so that while the heel is in coupled to the sole, that shoulder remains embedded within that cavity, locking against the rotation between heel and sole, and at the time of the decoupling of the heel, just The user presses the underside of the lug (on the underside of the shoe), thus disengaging the lug from the inside of the heel cavity, and can then rotate the heel and detach it from the sole.
