DISPOSIÇÃO CONSTRUTIVA APLICADA EM BLOCO FIXADOR COM PROJEÇÃO DE CAVILHA PARA MÓVEIS DE MADEIRA CONSTRUCTION DISPOSITION APPLIED IN FIXING BLOCK WITH DOWEL PROJECTION FOR WOODEN FURNITURE

BREVE INTRODUÇÃO BRIEF INTRODUCTION

[001] Trata-se o presente pedido de patente de uma nova DISPOSIÇÃO CONSTRUTIVA APLICADA EM BLOCO FIXADOR COM PROJEÇÃO DE CAVILHA PARA MÓVEIS DE MADEIRA, na qual consiste em um bloco semi-oblongo, monobloco, contendo numa superfície três projeções de configurações distintas, sendo duas projeções de maior altura, com núcleo vazado e a outra projeção menor e central de formato cilíndrico, ambas com a função de cravação do bloco fixador no rebaixo usinado na chapa de madeira. Ortogonalmente a estas três projeções citadas, é composta de uma outra projeção, de disposição construtiva cilíndrica com anéis de ranhuras, que tem a função de uma cavilha, fazendo a junção entre duas chapas madeira. [001] This patent application concerns a new CONSTRUCTION DISPOSITION APPLIED TO A FIXING BLOCK WITH A DOWEL PROJECTION FOR WOODEN FURNITURE, which consists of a semi-oblong, monobloc block, containing on one surface three projections of different configurations, two of which are taller, with a hollow core, and the other smaller, central projection of a cylindrical shape, both with the function of driving the fixing block into the recess machined in the wooden sheet. Orthogonally to these three projections mentioned, it is composed of another projection, with a cylindrical construction arrangement with groove rings, which has the function of a dowel, making the joint between two wooden sheets.

[002] A cravação do bloco fixador com cavilha, é por meio de suas projeções e tem um auxílio complementar de fixação, através de uma colagem de material poliuretano muito conhecido como fixador de PU que é inserido nas referidas projeções do bloco fixador e nas furações usinadas nas chapas da madeira. Importante destacar que a utilização do PU, é opcional, sendo viável apenas como reforço. [002] The fixing block is driven in with a dowel by means of its projections and has an additional fixing aid, through a bonding of polyurethane material, well known as PU fastener, which is inserted into the aforementioned projections of the fixing block and into the holes machined in the wood sheets. It is important to highlight that the use of PU is optional, being viable only as reinforcement.

CAMPO DE APLICAÇÃO FIELD OF APPLICATION

[003] O bloco fixador com projeção cilíndrica com função de cavilha é empregado no segmento de componentes do mobiliário. O bloco fixador, também pode ser denominado no mercado consumidor, como conector ou suporte. [003] The fixing block with cylindrical projection with dowel function is used in the furniture components segment. The fixing block can also be called in the consumer market as a connector or support.

ESTADO DA TÉCNICA STATE OF THE TECHNIQUE

[004] No atual estado da técnica a junção entre duas peças de mobília, como por exemplo, uma prateleira fixa nas chapas laterais da cômoda, é feita por cavilhas de madeira. Outro meio de fixação é por um kit, contento parafuso e tambor, ou seja, duas peças, além de uma peça de acabamento. Há outros kits que possuem mais de três peças de fixação independentes, contendo ou não a peça de acabamento. [005] No caso, a cavilha de madeira, não obtém muita aderência pois sua cravação é feita na espessura da chapa, região de baixa resistência, principalmente de chapas de compensados, aglomerados, mesmo inserindo cola de madeira ou cola de PU para melhorar a aderência. [004] In the current state of the art, the joint between two pieces of furniture, such as a shelf fixed to the side panels of a dresser, is made using wooden dowels. Another means of fixing is by means of a kit, containing a screw and a barrel, i.e., two pieces, in addition to a finishing piece. There are other kits that have more than three independent fixing pieces, whether or not containing the finishing piece. [005] In this case, the wooden dowel does not achieve much adhesion because it is driven into the thickness of the sheet, a region of low resistance, especially in plywood and chipboard sheets, even when using wood glue or PU glue to improve adhesion.

[006] Relacionado aos kits de fixação, tem sua composição de um bloco metálico circular com vazado central e fendas circulares, e a outra peça é um parafuso. O bloco metálico circular é inserido no rebaixo usinado na chapa, e assim insere o parafuso entre as fendas do bloco circular, e insere a ponta roscada do parafuso no furo de outra chapa, para fazer a união de duas peças do móvel (prateleira e chapa de estrutura do móvel). Após inserir o parafuso no furo, utiliza-se uma chave apropriada a cabeça do parafuso, geralmente chave fenda cruzada, conhecida por “chave Philips” ou chave de fenda. O aperto é inserido a chave no núcleo central do bloco circular metálico, exigindo habilidade. Outras formas de aperto ou travamento do parafuso no bloco circular, no entanto, é de complexo. [006] Related to the fixing kits, it is composed of a circular metal block with a central hole and circular slots, and the other part is a screw. The circular metal block is inserted into the recess machined in the sheet metal, and thus inserts the screw between the slots in the circular block, and inserts the threaded end of the screw into the hole in another sheet metal, to join two pieces of furniture (shelf and frame plate of the furniture). After inserting the screw into the hole, a wrench appropriate to the head of the screw is used, usually a cross-head screwdriver, known as a “Philips screwdriver” or flathead screwdriver. The tightening is done by inserting the wrench into the central core of the circular metal block, requiring skill. Other ways of tightening or locking the screw in the circular block, however, are complex.

[007] Outro fato é de o kit ter as peças independentes, que na montagem de um móvel de grande proporção e de inúmeras prateleiras, ocorre na montagem algumas perdas de peças, ou por outros motivos, como o distanciamento do parafuso com relação ao bloco circular (peças espalhadas), que ocupa tempo do montador buscar e juntar essas peças, que resulta na demora da montagem. Ainda é importante tomar ciência, que este kit, utiliza-se de uma grande quantidade de metal para sua realização, envolvendo torneiros mecânicos e entre outros processos de fabricação. [008] Em pesquisas elaboradas em site de buscas de patentes, foi encontrada um documento de patentes, no qual não é relevante ao pedido de patente proposto. A seguir, apresenta-se o documento encontrado e na sequência as diferenças entre o documento e o proposto neste pedido de patente. [007] Another fact is that the kit has independent parts, which means that when assembling a large piece of furniture with numerous shelves, some parts are lost during assembly, or for other reasons, such as the distance between the screw and the circular block (scattered parts), which takes up the assembler's time searching for and putting these parts together, which results in delayed assembly. It is also important to be aware that this kit uses a large amount of metal for its construction, involving mechanical lathes and other manufacturing processes. [008] In research carried out on a patent search website, a patent document was found that is not relevant to the proposed patent application. The document found is presented below, followed by the differences between the document and the one proposed in this patent application.

This new construction method increases the stability of the fixing between the parts, significantly improving the final appearance of the assembled furniture.

[010] Esse documento revela melhoria perante os kits já citados nos parágrafos anteriores. Nota-se que este kit ainda é composto de peças independentes e exige ferramentas de aperto, mesmo que seja menos ferramentas que os modelos anteriores do estado da técnica. Uma ilustração desse conector será apresentada em anexo nesse pedido de patente para gerar melhor clareza das diferenças do proposito do pedido de patente. [010] This document shows an improvement over the kits already mentioned in the previous paragraphs. It should be noted that this kit is still composed of independent parts and requires tightening tools, even if it is fewer tools than the previous models of the state of the art. An illustration of this connector will be presented in the annex to this patent application to generate better clarity of the differences in the purpose of the patent application.

[011] O pedido de patente proposto, elimina peças independentes, ou seja, peças separadas, pois a peça de fixação é única, monobloco contento todas as peças unificadas que realiza a cravação do bloco fixador, além da fixação entre chapas de madeira. [011] The proposed patent application eliminates independent parts, that is, separate parts, as the fixing part is unique, a monoblock containing all the unified parts that perform the driving of the fixing block, in addition to the fixing between wooden sheets.

Esta nova forma construtiva aplicada em conector proporciona montagem fácil, rápida e intuitiva sem a utilização de ferramenta. Além disso, reduz o número de ferragens para a montagem, elimina os custos de montagem ao consumidor final e reduz o custo de fabricação do móvel com a diminuição de processos de usinagem. [012] DOCUMENT: BR 202020021646-0 - PUBLICATION DATE: 03/05/2022 - improvement applied to a connector for assembling furniture, which is the object of this patent, aims to solve the drawbacks described in the state of the art through connectors equipped with construction forms that allow fixing without the use of tools due to the connectors being equipped with a specific shape and rear projections that fit into predetermined holes along the faces of the parts, ensuring that the end consumer can assemble their furniture without relying on specialized assemblers. This new construction form applied to a connector provides easy, fast and intuitive assembly without the use of tools. In addition, it reduces the number of hardware for assembly, eliminates assembly costs for the end consumer and reduces the cost of manufacturing the furniture by reducing machining processes.

[013] O conector trata-se de peça única, e de formato em “L” contento duas formas cilíndricas de função de cavilha. O conector tem a finalidade de fixação entre duas chapas de móveis, é um conector que quando instalado fica aparente, além de ser instalado somente pelo lado externo do móvel. Pode-se considerar esse conector como uma cantoneira ou suporte em “L”. Está em anexo uma ilustração do conector, para verificação das diferenças construtivas e do propósito de uso quando comparado com o pedido de patente. [013] The connector is a single piece, and has an “L” shape containing two cylindrical shapes that act as dowels. The connector is intended for fixing two furniture sheets together. It is a connector that is visible when installed, in addition to being installed only on the outside of the furniture. This connector can be considered as a corner or “L” support. An illustration of the connector is attached to verify the construction differences and the intended use when compared to the patent application.

DO NOVO MODELO PROPOSTO OF THE NEW PROPOSED MODEL

[014] O novo bloco fixador com projeção cilíndrica com a função de cavilha é projetado em uma peça única, ou seja, monobloco, que dispensa, uma peça complementar e de uma outra peça, no caso, uma tampa de acabamento. Afixação ou cravação do bloco é feita pela introdução no rebaixo usinado na chapa de madeira, e a fixação é por meio de três projeções de diferentes formas construtivas, sendo duas vazadas, com dois propósitos, para economia de material, e quando optado a utilização de cola de PU, os vazados geram uma maior aderência e fixação entre o bloco e a chapa. Ainda o bloco fixador monobloco, ortogonalmente numa das projeções, é presente por uma outra projeção cilíndrica com anéis perimetrais, para obter uma função de cavilha, que faz junção entre duas placas de madeira. [014] The new cylindrical projection fixing block with the function of a dowel is designed in a single piece, i.e., monoblock, which does not require a complementary piece and another piece, in this case, a finishing cap. The block is fixed or driven by inserting it into the recess machined in the wooden sheet, and the fixing is done by means of three projections of different construction forms, two of which are hollow, with two purposes, to save material, and when the use of PU glue is chosen, the hollows generate greater adhesion and fixation between the block and the sheet. Furthermore, the monoblock fixing block, orthogonally in one of the projections, is present by another cylindrical projection with perimeter rings, to obtain a dowel function, which makes a joint between two wooden sheets.

[015] Essa última projeção, de disposição cilíndrica que define numa cavilha, tem a função de unir e fixar duas chapas de madeira, obtendo a montagem do móvel. [015] This last projection, with a cylindrical arrangement that defines a dowel, has the function of joining and fixing two wooden sheets, obtaining the assembly of the furniture.

[016] De acordo com o propósito funcional e as características construtivas, considera-se num bloco fixador com cavilha, em peça única, como descrito nos parágrafos anteriores, e proporciona inúmeras vantagens, desde sua fabricação, como melhorias funcionais no uso. [016] According to the functional purpose and construction characteristics, it is considered a fixing block with a dowel, in a single piece, as described in the previous paragraphs, and provides numerous advantages, since its manufacture, such as functional improvements in use.

[017] Um bloco fixador que não precisa de ferramenta de aperto, como chave de fenda, peças complementares, além de facilidade de cravação, que torna a montagem do móvel rápida, sem contratempos. [017] A fixing block that does not require tightening tools, such as a screwdriver, additional parts, in addition to being easy to drive, which makes furniture assembly quick and hassle-free.

[018] Importante destacar que o bloco fixador, quando instalado, apresenta duas funções, uma de tampa acabamento e a outra de uma tampa limitadora de profundidade do bloco fixador. O bloco fixador, desempenha a função tampa, devido a sua disposição construtiva semi-oblonga, de maior comprimento e largura quando comparado com o diâmetro das projeções circulares. [019] O bloco fixador com a disposição construtiva semi-oblonga, que define uma tampa de acabamento, permite que, com sua área perimetral esconde as rebarbas causadas nas furações da chapa da madeira, furações essas para serem alojadas as projeções cilíndricas do bloco fixador. [018] It is important to highlight that the fixing block, when installed, has two functions, one as a finishing cover and the other as a depth limiting cover for the fixing block. The fixing block performs the cover function due to its semi-oblong construction arrangement, which is longer and wider when compared to the diameter of the circular projections. [019] The fixing block with the semi-oblong construction arrangement, which defines a finishing cover, allows, with its perimeter area, to hide the burrs caused by the holes in the wood sheet, holes that house the cylindrical projections of the fixing block.

[020] No caso de o bloco fixador exercer a função da tampa limitadora, funciona como um batente, pois caso um dos furos feitos na madeira tenha uma profundidade maior que o das projeções, a área perimetral do bloco fixador assenta na superfície da madeira, impedindo que o bloco fixador fique desnivelado, ou seja, rebaixado perante a superfície da chapa da madeira. [020] If the fixing block acts as a limiting cover, it acts as a stop, because if one of the holes made in the wood has a greater depth than the projections, the perimeter area of the fixing block rests on the surface of the wood, preventing the fixing block from becoming uneven, that is, lowered in relation to the surface of the wood sheet.

[021] A importância de o bloco fixador ficar sobreposto a superfície da chapa de madeira, não é só pela estética, mas também pelo aspecto técnico, pois mantém a projeção cilíndrica com função de cavilha alinhada ao furo executado na outra chapa de madeira para ser introduzido. [021] The importance of the fixing block being placed on top of the surface of the wooden sheet is not only for aesthetic reasons, but also for the technical aspect, as it maintains the cylindrical projection with the function of a dowel aligned with the hole made in the other wooden sheet to be inserted.

DA DESCRIÇÃO TÉCNICA TECHNICAL DESCRIPTION

[023] A nova DISPOSIÇÃO CONSTRUTIVA APLICADA EM BLOCO FIXADOR COM PROJEÇÃO DE CAVILHA PARA MÓVEIS DE MADEIRA, objeto desta solicitação de pedido de patente, consiste em um bloco fixador (1) de formato semi-oblongo (1A), contendo em sua superfície (S1) três projeções (2) de configurações distintas, sendo duas projeções de maiores alturas (2A), com núcleos vazados (3) e a outra projeção de menor altura (2B) e central de formato cilíndrico (4). [023] The new CONSTRUCTION DISPOSITION APPLIED IN A FIXING BLOCK WITH A DOWEL PROJECTION FOR WOODEN FURNITURE, the object of this patent application request, consists of a fixing block (1) with a semi-oblong shape (1A), containing on its surface (S1) three projections (2) with different configurations, two of which are higher projections (2A), with hollow cores (3) and the other projection is lower in height (2B) and has a central cylindrical shape (4).

[024] Importante destacar que as projeções de maior altura (2A), são distintas entre si, sendo uma de projeção cilíndrica (2A) com anéis de ranhuras (A), enquanto a outra é uma projeção semicilíndrica (2A”). [024] It is important to highlight that the highest projections (2A) are distinct from each other, one being a cylindrical projection (2A) with groove rings (A), while the other is a semi-cylindrical projection (2A”).

[025] As três projeções (2) tem a função de cravação do bloco fixador (1) no rebaixo (R) usinado na chapa de madeira (M). [025] The three projections (2) have the function of driving the fixing block (1) into the recess (R) machined in the wooden sheet (M).

[026] Ortogonalmente a projeção semicilíndrica (2A”), é composta de uma outra projeção cilíndrica (2C), com anéis de ranhuras (A), que tem a função de uma cavilha, que faz a junção entre duas chapas de madeiras (M). [026] Orthogonally, the semi-cylindrical projection (2A”) is composed of another cylindrical projection (2C), with groove rings (A), which has the function of a dowel, which forms the joint between two wooden sheets (M).

[027] O bloco fixador (1) na superfície (S2), é liso e com o perímetro semiboleado (B) que exerce a função de tampa (T). Ainda na superfície (S2) é lisa, e define nua área destinada para inserir numeração de série de fabricação, logotipo ou outras informações, por meio de gravações de alto e/ou baixo relevo, além de possibilitar outro meio de aplicação, como o uso de adesivos. Importante destacar que a aplicação de informações na superfície (S2) fica a critério do fabricante. [027] The fixing block (1) on the surface (S2) is smooth and has a semi-rounded perimeter (B) that acts as a lid (T). The surface (S2) is also smooth and defines an area intended for inserting the manufacturing serial number, logo or other information, by means of high and/or low relief engravings, in addition to enabling another means of application, such as the use of stickers. It is important to highlight that the application of information on the surface (S2) is at the discretion of the manufacturer.

[028] A cravação do bloco fixador (1) no rebaixo usinado na madeira (M), é por meio de suas projeções (2A) e (2B), e opcionalmente tem um auxílio de fixação, através de uma colagem com material poliuretano muito conhecido como fixador de PU que é colocado nas referidas projeções (2) do bloco fixador (1), e inserido nos rebaixos usinados nas chapas da madeira (M). Ajunção entre duas chapas de madeira (M), é feita pelo bloco fixador (1) por meio da projeção cilíndrica (2C) que é introduzida no orifício da chapa da madeira (M). [028] The fixing block (1) is driven into the recess machined in the wood (M) by means of its projections (2A) and (2B), and optionally has a fixing aid, through a gluing with polyurethane material well known as PU fixative that is placed in the said projections (2) of the fixing block (1), and inserted into the recesses machined in the wood sheets (M). The joint between two wood sheets (M), is made by the fixing block (1) through the cylindrical projection (2C) that is introduced into the hole in the wood sheet (M).
