Description

DESCRIPCIONDESCRIPTION

Una cadena con elementos identicos entrelazados mutuamente entre s^A chain with identical elements intertwined with each other ^

La invencion se refiere a una cadena para joyas, hecha de metales preciosos y no preciosos, constituida por una sucesion de elementos identicos y concatenados mutuamente entre stThe invention relates to a chain for jewels, made of precious and non-precious metals, constituted by a succession of identical and mutually concatenated elements between st

En la industria de la bisutena y la joyena en general, hay varios ejemplos de cadenas con elementos identicos concatenados entre stIn the industry of bisutena and joyena in general, there are several examples of chains with identical elements concatenated between st

A veces, dichos elementos estan constituidos por anillos cerrados para que el anillo siguiente que se concatene con el anterior se inserte y se suelde luego a fin de cerrar la abertura del mismo, a fin de formar una sucesion de elementos de cadena resistentes a cualquier tension.Sometimes, said elements are constituted by closed rings so that the next ring that concatenates with the previous one is inserted and then welded in order to close the opening thereof, in order to form a succession of chain elements resistant to any tension .

Tambien se conocen construcciones de cadenas en las que cada elemento esta conectado al siguiente a traves de una operacion de plegado que confiere al elemento una forma sustancialmente similar a una caja.Also known are chain constructions in which each element is connected to the next through a folding operation that gives the element a shape substantially similar to a box.

En construcciones de este tipo, las partes terminales que se cierran unas sobre otras para obtener una forma similar a una caja se someten a veces a tensiones que permiten abrir el elemento de nuevo y por consiguiente romper la cadena.In constructions of this type, the terminal parts that are closed over each other to obtain a box-like shape are sometimes subjected to tensions that allow the element to be opened again and consequently to break the chain.

Con el objetivo de superar dicho inconveniente, se propuso reforzar el elemento que constituye la cadena, especialmente en la parte terminal, por ejemplo aumentando el grosor de la misma, para que la parte en cuestion no pueda abrirse facilmente a menos que este sometida a cargas de tension particularmente altas.In order to overcome this inconvenience, it was proposed to reinforce the element that constitutes the chain, especially in the terminal part, for example by increasing the thickness thereof, so that the part in question cannot be opened easily unless it is subjected to loads of particularly high tension.

Sin embargo, incluso esta solucion no permite alcanzar el nivel de seguridad requerido para garantizar que la cadena, por ejemplo, si se somete a un movimiento brusco de tiron o a tensiones inesperadas, no se abra y rompa.However, even this solution does not allow to reach the level of security required to ensure that the chain, for example, if it is subjected to an abrupt movement of tiron or unexpected tensions, does not open and break.

Sin embargo, los fabricantes de cadenas de bisutena o de joyas ornamentales todavfa se esfuerzan por obtener cadenas constituidas por elementos que puedan concatenarse entre sf y sin soldadura.However, manufacturers of bisutena chains or ornamental jewels still strive to obtain chains consisting of elements that can be concatenated between themselves and without welding.

Esto con el claro objetivo de evitar especialmente realizar, en la soldadura en cuestion, operaciones costosas tales como la soldadura, asf como operaciones de acabado estetico que sean largas, caras y que a veces no logren la perfeccion estetica requerida en construcciones de este tipo.This with the clear objective of especially avoiding, in the welding in question, expensive operations such as welding, as well as aesthetic finishing operations that are long, expensive and sometimes do not achieve the aesthetic perfection required in constructions of this type.

El documento de la tecnica anterior EP 1943 916 A2 del mismo Solicitante divulga una cadena que comprende elementos en forma de jaula conectados en sucesion y que comprende un cuerpo central desde el que se ramifican cuerpos laterales cuyos extremos libres estan dispuestos uno en frente de otro, insertados de manera deslizante en otro elemento en forma de jaula adyacente al elemento en forma de jaula y orientado hacia el cuerpo central correspondiente. La cadena comprende un elemento elastico interpuesto entre los extremos libres de los cuerpos laterales de cada elemento en forma de jaula y el cuerpo central del elemento en forma de jaula adyacente.The prior art document EP 1943 916 A2 of the same Applicant discloses a chain comprising cage-shaped elements connected in succession and comprising a central body from which lateral bodies are branched whose free ends are arranged in front of each other, inserted in a sliding manner in another cage-shaped element adjacent to the cage-shaped element and oriented towards the corresponding central body. The chain comprises an elastic element interposed between the free ends of the side bodies of each cage-shaped element and the central body of the adjacent cage-shaped element.

El objetivo de la presente invencion es proporcionar un collar con elementos mutuamente concatenados capaces de superar los inconvenientes indicados anteriormente. El objetivo principal de la presente invencion es proporcionar una cadena en la que cada elemento que lo forme se concatene al otro para que los elementos, aunque no esten provistos de soldadura alguna, no se abran incluso cuando se sometan a fuertes tensiones de traccion de la cadena.The aim of the present invention is to provide a collar with mutually concatenated elements capable of overcoming the drawbacks indicated above. The main objective of the present invention is to provide a chain in which each element that forms it is concatenated to the other so that the elements, although not provided with any welding, do not open even when subjected to strong tensile stresses of the chain.

Otro objetivo de la presente invencion es proporcionar una cadena que sea facil de montar y que este constituida por elementos que sean faciles de obtener a traves de operaciones mecanicas simples tales como operaciones de corte, curvado y conformacion.Another objective of the present invention is to provide a chain that is easy to assemble and that is constituted by elements that are easy to obtain through simple mechanical operations such as cutting, bending and forming operations.

Los objetivos mencionados anteriormente y otros objetivos que deben destacarse en la descripcion indicada mas adelante se obtienen mediante una cadena para joyas cuyas caractensticas estan de acuerdo con el contenido de la primera reivindicacion.The aforementioned objectives and other objectives that should be highlighted in the description indicated below are obtained by a chain for jewels whose characteristics are in accordance with the content of the first claim.

Ventajosamente, de acuerdo con la invencion, la cadena esta formada por una sucesion de elementos en los que cada elemento que esta conectado al siguiente tiene forma de caja y tiene dos partes simetricas plegadas una sobre otra. Cada parte tiene dos apendices esencialmente plegados en 90° que forman el elemento resistente que contrasta con el cuerpo central o la parte inferior del elemento que esta sometido a tension.Advantageously, according to the invention, the chain is formed by a succession of elements in which each element that is connected to the next is box-shaped and has two symmetrical parts folded one upon another. Each part has two appendixes essentially folded in 90 ° that form the resistant element that contrasts with the central body or the lower part of the element that is under tension.

Por consiguiente, las partes terminales de cada elemento, que estan superpuestas entre sf y que podnan abrirse si se someten a tension, realmente nunca se someten a tension ya que toda la posible tension de traccion a la que se somete el elemento con respecto a la otra se absorbe por los apendices dispuestos simetricamente para que ofrezcan el maximo modulo de resistencia a la flexion bajo la tension de traccion.Therefore, the terminal parts of each element, which are superimposed on each other and that could be opened if they are subjected to tension, never really undergo tension since all the possible tension of tension to which the element is subjected with respect to the another is absorbed by the symmetrically arranged appendages so that they offer the maximum flexural strength modulus under tensile stress.

Otras caractensticas y detalles de la invencion resultaran mas evidentes a partir de la descripcion de un modo de realizacion preferido de la invencion, indicada a continuacion a modo de ejemplo no limitativo, con referencia a los dibujos adjuntos, en donde: Other features and details of the invention will become more apparent from the description of a preferred embodiment of the invention, indicated below by way of non-limiting example, with reference to the attached drawings, where:

Con referencia a la fig. 1, se puede observar que la cadena para joyas comprende una pluralidad de elementos indicados con 1 que luego se concatenaran mutuamente directamente entre sf.With reference to fig. 1, it can be seen that the jewelry chain comprises a plurality of elements indicated by 1 that will then concatenate each other directly between each other.

Como se observa en la fig. 1, cada elemento 1 esta formado por dos partes simetricas indicadas con 2 y con 3 unidas entre sf por un cuerpo central 4 esencialmente curvado.As shown in Fig. 1, each element 1 is formed by two symmetrical parts indicated with 2 and 3 joined together by an essentially curved central body 4 .

Cada una de las dos partes 2 y 3 tiene un cuerpo esencialmente longitudinal, indicado con 20 y 30, que esta provisto de dos apendices 21, 22; 31, 32 dispuestos en los lados opuestos con respecto al eje longitudinal X-X de dicho elemento, y con una parte terminal 23; 33.Each of the two parts 2 and 3 has an essentially longitudinal body, indicated with 20 and 30 , which is provided with two appendages 21 , 22 ; 31 , 32 arranged on opposite sides with respect to the longitudinal axis XX of said element, and with a terminal part 23 ; 33 .

Dichos apendices y dicha parte terminal se plegaran posteriormente durante la operacion de plegado y curvado, como se observa en la fig. 2.Said appendices and said terminal part will be folded later during the folding and bending operation, as seen in fig. two.

Basicamente, las partes 2 y 3 se pliegan solas separadas entre sf debido a la presencia del cuerpo central 4 y cerrandose para formar una forma similar a una caja dado que las partes terminales 23 y 33 estan acopladas adherentes entre sf.Basically, parts 2 and 3 fold alone apart from each other due to the presence of the central body 4 and closing to form a box-like shape since the end parts 23 and 33 are adherently coupled to each other.

Como se puede observar en la fig. 5, con referencia particular a los elementos mutuamente concatenados que ahora se indican con a y b, debena observarse que el elemento b esta posicionado, con respecto al elemento a, para que el cuerpo central 4b o la parte inferior del mismo este dispuesto en el espacio entre el cuerpo central 4a del elemento a y los apendices 22a y 32a que todavfa pertenezcan al cuerpo central 4a.As can be seen in fig. 5, with particular reference to the mutually concatenated elements that are now indicated with a and b , it should be noted that element b is positioned, relative to element a , so that the central body 4b or the lower part thereof is arranged in the space between the central body 4a of the element a and the appendages 22a and 32a that still belong to the central body 4a .

Por consiguiente, cuando el elemento b se somete a tension por cualquier motivo, dado que esta concatenado a otros, la parte inferior 4b contrasta con los dos apendices 22a y 32a del cuerpo 4a sin someter nunca las dos partes terminales 23a y 33a plegadas sobre sf mismas a tension y por consiguiente son faciles de abrir bajo una tension considerable.Therefore, when the element b is subjected to tension for any reason, since it is concatenated to others, the lower part 4b contrasts with the two appendixes 22a and 32a of the body 4a without ever subjecting the two terminal parts 23a and 33a folded on each other. themselves to tension and therefore are easy to open under considerable tension.

La informacion proporcionada con referencia a la fig. 5 tambien se pueden observar facilmente en la fig. 7, que muestra la seccion de la pieza de cadena segun la lmea A-A mostrada en la fig. 6.The information provided with reference to fig. 5 can also be easily seen in fig. 7, which shows the section of the chain piece according to the line A-A shown in fig. 6.

Por consiguiente, el hecho de descargar la tension de traccion exclusivamente en los apendices 22a y 32a por el elemento b causa una fuerte resistencia a la tension en toda la cadena dado que la parte inferior 4b ejerce la tension en los apendices 22a y 32a que estan dispuestos a fin de ofrecer el maximo modulo de resistencia a la flexion. Consequently, the fact of discharging the tension of traction exclusively in the appendices 22a and 32a by the element b causes a strong resistance to the tension in the whole chain since the lower part 4b exerts the tension in the appendices 22a and 32a that are ready to offer the maximum flexural strength module.

En realidad, como se observa en la fig. 2, cada uno de los apendices 22a y 32a actua como una viga encajada en la seccion S que tiene una forma esencialmente rectangular, donde la fuerza F se aplica de acuerdo con una direccion Y paralela a la direccion del eje mayor de la seccion. Por consiguiente, dicha seccion esta dispuesta en la configuracion que ofrece el valor maximo del modulo de resistencia a la flexion contra el momento de flexion generado por la fuerza F y que actua sobre el mismo.Actually, as seen in fig. 2, each of the appendages 22a and 32a acts as a beam embedded in the section S which has an essentially rectangular shape, where the force F is applied according to a direction Y parallel to the direction of the major axis of the section. Therefore, said section is arranged in the configuration that offers the maximum value of the flexural strength module against the moment of flexion generated by the force F and acting on it.

De acuerdo con el ejemplo mostrado, se observa por consiguiente que los elementos concatenados mutuamente entre sf sin soldadura alguna, pero exclusivamente cerrados y plegados sobre sf mismos, son capaces de garantizar una resistencia absolutamente comparable a la de los elementos concatenados entre sf y soldados.According to the example shown, it is therefore observed that the elements concatenated mutually between each other without welding, but exclusively closed and folded on themselves, are capable of guaranteeing a resistance absolutely comparable to that of the elements concatenated between sf and welded.

Por consiguiente, se alcanzan todos los objetivos de la invencion; en particular, el proposito era lograr una resistencia maxima de la cadena a un tiron repentino, aunque dicha cadena esta constituida por elementos mutuamente concatenados y plegados entre sf, sin requerir ningun tipo de soldadura.Consequently, all the objectives of the invention are achieved; in particular, the purpose was to achieve a maximum resistance of the chain to a sudden tiron, although said chain is constituted by mutually concatenated elements folded together, without requiring any type of welding.

Por consiguiente, la construccion se vuelve simple y se puede llevar a cabo con maquinas automaticas.Consequently, the construction becomes simple and can be carried out with automatic machines.

Ademas, el acabado de las cadenas ornamentales asf obtenidas tambien es simple, ya que no requiere operaciones adicionales para eliminar los defectos esteticos visibles. In addition, the finishing of the ornamental chains thus obtained is also simple, since it does not require additional operations to eliminate visible aesthetic defects.
