Description

Dispositivo de apertura - cierre de un elemento, principalmente de un cajón, móvil en relación a otro elemento constituido por el armazón de un mueble especialmente desplazable sobre ruedas.Opening device - closing an item, mainly from a drawer, mobile in relation to another element constituted by the frame of a particularly movable furniture on wheels.

La presente invención está relacionada con un dispositivo de apertura - cierre de un elemento, principalmente de un cajón, móvil con relación a otro elemento constituido por el armazón de un mueble principalmente desplazable sobre ruedas, del tipo descrito en el preámbulo de la reivindicación 1.The present invention is related to a opening device - closing an element, mainly of a drawer, mobile in relation to another element constituted by the frame of a furniture mainly movable on wheels, of type described in the preamble of claim 1.

La invención tiene por objeto suministrar un dispositivo simple, de realización económica y sin embargo muy robusto y fiable. En particular, ese dispositivo debe ser capaz de garantizar la ausencia de apertura intempestiva del elemento móvil cuando éste está constituido por un elemento de apertura, montado sobre rodamientos de bolas, de una mesa u otro mueble desplazable sobre ruedas y sometido, debido a ello, a fuertes sacudidas durante su desplazamiento sobre un suelo irregular.The object of the invention is to provide a simple device, economical and yet very robust and reliable. In particular, that device must be able to guarantee the absence of untimely opening of the mobile element when it is constituted by an opening element, mounted on ball bearings, a table or other movable furniture on wheels and subjected, therefore, to strong shocks during its displacement on an irregular ground.

La DE-A-39 30 271 describe un dispositivo del tipo indicado al principio, aplicado a la apertura - cierre de un cenicero de automóvil. En ese contexto, la carrera de apertura del elemento móvil es muy corta, de manera que el pestillo circula en el sistema de bloqueo estando constantemente en posición sobre éste último, que le guía permanentemente. Una solución como ésa no es conveniente en el caso de un elemento abridor de mueble, tal como un cajón, cuya carrera de apertura es mucho más grande, de forma que el pestillo debe poder alejarse de manera considerable del bloque de bloqueo.DE-A-39 30 271 describes a device of the type indicated at the beginning, applied to the opening - closing of an automobile ashtray. In that context, the opening stroke of the mobile element is very short, so that the latch circulates in the locking system while constantly in position on the latter, which guides you permanently. A solution like that is not convenient in the case of a furniture opener, such as a drawer, whose  opening is much larger, so that the latch must be able to move away considerably from the blocking block.

Para resolver el particular problema técnico planteado por los elementos abridores de los muebles desplazables, el dispositivo de apertura - cierre según la invención está caracterizado por la parte caracterizante de la reivindicación 1.To solve the particular technical problem raised by the opener elements of the movable furniture, the opening-closing device according to the invention is characterized by the characterizing part of the claim one.

El espaciamiento horizontal d, medido perpendicularmente a la pared 12 (figura 1), entre la extremidad superior de la rampa 20 y la de la rampa 18, es inferior al diámetro del hilo que constituye el pestillo 3. Además, el abultamiento 18A que une la cavidad 17 a la rampa 18 se encuentra a un nivel superior al del eje.The horizontal spacing d , measured perpendicularly to the wall 12 (Figure 1), between the upper end of the ramp 20 and that of the ramp 18, is smaller than the diameter of the thread constituting the latch 3. Furthermore, the bulge 18A that joins the cavity 17 to the ramp 18 is at a level higher than the axis.

El resorte de apertura 7 es un resorte helicoidal cuya extremidad se ha hecho solidaria con la pared 12 del armazón por medio de un pitón de montaje 21.The opening spring 7 is a helical spring whose limb has become integral with wall 12 of the frame by means of a mounting python 21.

Se describirá ahora el funcionamiento del dispositivo en relación con las Figuras 3 y 4.The operation of the device in relation to Figures 3 and 4.

Al comienzo, estando abierto el cajón 1, la rama trasera del pestillo se encuentra en el mismo plano horizontal que su rama delantera 8, en relación con un punto intermedio de la rampa 16.At the beginning, when drawer 1 is open, the branch rear of the latch is in the same horizontal plane as its front branch 8, in relation to an intermediate point of the ramp 16.

Para cerrar el cajón, se le empuja hacia atrás, es decir hacia la derecha de la figura 3. La rama 22 hace contacto con la rampa 16, y despuéss sube a lo largo de ella par encontrarse con la rama superior del resorte 5 (flecha F1 de la figura 3). Durante esta subida, la cara trasera 9 del cajón comprime al resorte 7.To close the drawer, it is pushed back, that is to the right of figure 3. Branch 22 makes contact with ramp 16, and then climbs along it to meet with the upper branch of spring 5 (arrow F1 of figure 3). During this rise, the rear face 9 of the drawer compresses the spring  7.

En lo alto de la rampa 16, la rama 22 hace tope contra la extremidad superior de la guía 19, la cual le hace descender otra vez hasta su punto trasero 23, situado en relación a la cavidad 17.At the top of ramp 16, branch 22 stops against the upper extremity of guide 19, which makes descend again to its rear point 23, located in relation to the cavity 17.

El operador no puede entonces hacer retroceder más el cajón. Relaja su presión, de forma que el resorte 7 rempuja el cajón hacia adelante, lo que lleva la rama 22 del pestillo a su alojamiento en la cavidad17.The operator cannot then roll back Plus the drawer. Relax your pressure, so that spring 7 replaces the drawer forward, which brings branch 22 of the latch to its accommodation in the cavity 17.

El cajón está entonces cerrado y bloqueado firmemente en esta posición, como se ilustra en la figura 4.The drawer is then closed and locked firmly in this position, as illustrated in figure 4.

Para abrir el cajón, el operador lo empuja de nuevo, brevemente, hacia la derecha de la figura 4. La rama 22 viene entonces a hacer contacto con la extremidad superior de la rama 20, y luego desciende a lo largo de ésta. Cuando el operador relaja su presión, el resorte 7 rempuja el cajón hacia la derecha, y, estando entonces el pestillo llevado a la posición horizontal por la rama superior del resorte 5, la rama 22 viene a hacer contacto con la extremidad superior de la rampa 18, y después es guiada por ésta hasta la parte baja del bloque 14 (flecha F2 de la figura 3), al encuentro de la rama inferior del resorte 5.To open the drawer, the operator pushes it from again, briefly, to the right of figure 4. Branch 22 comes then to make contact with the upper extremity of the branch 20, and then descends along it. When the operator relax your pressure, spring 7 pushes the drawer to the right, and, the latch being then brought to the horizontal position by the upper branch of the spring 5, the branch 22 comes to make contact with the upper limb of ramp 18, and then it is guided by it to the bottom of block 14 (arrow F2 of the Figure 3), to meet the lower branch of the spring 5.

Cuando la rama 22 ha sobrepasado hacia la izquierda el bloque 14, el resorte 5 vuelve a llevar al pestillo a su posición horizontal de reposo.When branch 22 has surpassed the Left the block 14, the spring 5 returns to the latch its horizontal resting position.

El dispositivo descrito anteriormente lleva un reducido número de piezas de realización económica, y robustas. Es fácil dimensionar las piezas y elegir la fuerza del resorte 7 para que el cajón no tenga el riesgo de desbloquearse de forma intempestiva en sus desplazamientos del mueble, conservando siempre un esfuerzo moderado de maniobra del cajón.The device described above carries a reduced number of pieces of economic realization, and robust. It is easy to size the parts and choose the force of the spring 7 to that the drawer does not have the risk of unlocking so untimely in their movements of furniture, always keeping a moderate effort to maneuver the drawer.
