Uma peça guia cilíndrica vazada, provida de abas laterais de fixação é colocada na cavidade da peça de apoio e uma haste com extremidade pontiaguda passa pela abertura central da peça guia e perfura a parede quando impulsionada pela força de um martelo, golpeado em sua outra extremidade, que é provida de um tampo tipo "copo" provido de uma cavidade superior com paredes com rosca fêmea para ser rosqueado na extremidade superior da haste. This object refers to an unprecedented device for perforating walls of various types of materials, plaster, cellular cement, concrete and so on. The device has a support piece in the form of a solid geometric body, with a central cavity, structure suitable for absorbing impacts and non-slip ability, and can be developed in various types of materials such as: PVC, plastic, wood, acrylic, among others. A hollow cylindrical guide piece provided with fixing side tabs is placed in the support piece cavity and a pointed end rod passes through the central opening of the guide piece and punctures the wall when driven by the force of a hammer struck at its other end. , which is provided with a "cup" cap provided with a female-walled upper cavity to be threaded into the upper end of the rod.
Destina-se o presente objeto a facilitar a perfuração de paredes de todos os tipos de materiais, pois a haste com extremidade pontiaguda, quando impulsionada pela força dos golpes de um martelo perfura a parede e a peça de apoio impede que o movimento seja feito para os lados ou de forma errada, evitando furos errados, fora de diâmetro e evitando que a parede seja quebrada ou lascada. A possibilidade de se fazer furos diferentes é muito menor porque o material da peça de suporte absorve muito bem e suporta a superfície de parede e o impacto quando a haste penetra na parede, principalmente quando é necessário fazer dois furos ou mais para pendurar algo na parede.
Além de evitar maiores danos e oferecer maior praticidade, o objeto em questão evita sujeiras, como é comum observarmos com uma furadeira, que perfura a parede e retira o material, levantando muito pó e deixando o ambiente sujo; nao necessida de energia elétrica, portando pode ser utilizado em qualquer lugar; é pequeno, leve e fácil de transportar; muito simples e prático de ser utilizado, portanto uma excelente alternativa para ser utilizado numa reforma ou construção. The present object is intended to facilitate the perforation of walls of all kinds of materials, as the pointed-tipped rod, when driven by the force of hammer blows, pierces the wall and the support piece prevents movement to wrong sides, avoiding wrong holes, out of diameter and preventing the wall from being broken or chipped. The possibility of drilling different holes is much smaller because the material of the support piece absorbs very well and supports the wall surface and the impact when the rod penetrates the wall, especially when it is necessary to drill two or more holes to hang something on the wall. . In addition to preventing further damage and offering greater practicality, the object in question avoids dirt, as we often observe with a drill that punctures the wall and removes the material, raising a lot of dust and leaving the environment dirty; No electric power needed, so can be used anywhere; It is small, light and easy to carry; Very simple and practical to use, so an excellent alternative for use in a renovation or construction.
A perfuração na parede é feita para que se coloque uma bucha e posteriormente um prego ou parafuso que irá segurar o objeto. De acordo com o tamanho da bucha a ser colocada, o tamanho e largura da haste podem variar. The perforation in the wall is made to place a bushing and later a nail or screw that will hold the object. Depending on the size of the bushing to be placed, the size and width of the rod may vary.
Para utilizar o dispositivo basta que o usuário marque um ponto na parede, onde quer fazer a perfuração; apoie a parte plana inferior da peça de apoio na parede, fazendo com que a extremidade pontiaguda da haste fique direcionada no ponto que foi marcado; a peça de apoio deve ser segurada firmemente e o usuário deve golpear um martelo sobre a extremidade do tampo superior tipo "copo" que é fixado na outra extremidade da haste; para tirar a haste da parede, depois de perfurada, a tampa deve ser girada e puxada para trás. To use the device, the user simply has to mark a point on the wall where he wants to drill; support the lower flat part of the support piece on the wall, making the pointed end of the rod point at the point that was marked; the support piece should be held firmly and the user should strike a hammer over the end of the "cup" top cap that is fixed to the other end of the rod; To remove the rod from the wall, after piercing, the cover must be turned and pulled back.
Estado da técnica: Até o momento a forma mais conhecida de se perfurar paredes de gesso, cimento celular ou outro tipo de material, é através da furadeira com brocas, que são apresentadas de algumas formas: a manivela, a bateria, elétrica e pneumática. Poréma furadeira apresenta alguns inconvenientes, entre eles: muitas vezes a broca sai da sua posição original ou perfura mais a parede do que necessário, fazendo com que um novo furo seja feito e aquele anterior deve ser coberto novamente com massa, o que desperdiça muito
mais tempo e material; quanto maior o tamanho da broca, maior a possibilidade do fura não sair como desejado, pois o usuário precisa fazer muita força para que a furadeira penetre na parede, principalmente numa parede de material mais firme, portanto a chance de errar é cada vez maior; a broca da furadeira penetra na parede e retira o material para fora, fazendo com que todo pó suje o ambiente; a maioria das furadeiras utilizadas e mais conhecidas atualmente, necessitam de energia elétrica, portanto não podem ser utilizada em qualquer lugar, além de não serem práticas de serem utilizadas, o que requer um mínimo de experiência com o equipamento, para que seja utilizado de forma correta. State of the art: So far the best known way to drill plaster walls, cellular cement or other material is through the drill with drills, which are presented in some ways: the crank, the battery, electric and pneumatic. However, the drill has some drawbacks, among them: often the drill goes out of its original position or pierces the wall more than necessary, causing a new hole to be drilled and the previous one to be covered again with grease, which wastes a lot. more time and material; the larger the drill bit size, the greater the chance that the hole will not come out as desired, as the user needs to push hard enough for the drill to penetrate the wall, especially a firmer material wall, so the chance of making a mistake is increasing; the drill bit penetrates the wall and pushes the material out, causing all dust to get in the environment; Most of today's most well-known drills require electrical power, so they cannot be used anywhere, and are not practical to use, which requires minimal equipment experience to use properly. correct.
