Abstract

The pair has a crossbar (1) whose end includes a gutter and a bolt, where the other end of the crossbar includes a cut (23) and another bolt. Another crossbar includes an end with a cut in which the gutter is inserted, and another end with a pin integrated to an axle of the latter crossbar and inserted in a housing of the former crossbar. The former bolt is released to integrate the pair and to facilitate transport of the pair. Each crossbar includes two articulations (2, 3) in which beveled upper ends of feet (4, 4', 5, 5') are housed, where the articulations are articulated.

Description

El presente invento tiene como objetivo aportar perfeccionamientos a diferentes modelos de caballetes o soportes de estructura del tipo caballete con pies plegables, tal y como se describe en la patente FR-2617944-A, de manera que The present invention aims to provide improvements to different models of easels or stands of easel type structure with folding feet, as described in patent FR-2617944-A, so that

simplifique el despliegue, lo haga automático y recupere los juegos de bloqueo. Este invento permite también asegurar un ensamblaje de dos caballetes independientes de manera muy segura y automática. La primera mejora reside en el dispositivo de bloqueo de las articulaciones que soportan los cuatro pies y que se Simplify deployment, do it automatically and recover blocking games. This invention also allows ensure an assembly of two independent stands in a very safe and automatic way. The first improvement lies in the joint blocking device that supports the four feet and that

pliegan en el interior de la traviesa con forma de U que forma la parte horizontal del caballete. Esta disposición permite, durante el despliegue de los pies, bloquear automáticamente las articulaciones mientras recupera los juegos de funcionamiento cuando la articulación llega al tope cuando los pies están por tanto desplegados y crea una inmovilización irreversible. fold inside the U-shaped sleeper that forms the horizontal part of the easel. This arrangement allows, during the deployment of the feet, automatically block the joints while recovering the operating games when the joint reaches the top when the feet are therefore deployed and creates an irreversible immobilization.

La segunda mejora reside en la forma, el desplazamiento de una respecto a otra de las dos articulaciones que The second improvement lies in the form, the displacement of one respect to another of the two joints that

permite superponer los pies plegados en el interior de la traviesa. Otra mejora concierne a una de las dos articulaciones que presenta una forma recortada permitiendo girar a la articulación y hacer tope de bloqueo sin necesidad de soldadura específica. allows to superimpose the folded feet inside the sleeper. Another improvement concerns one of the two joints that has a shortened shape allowing to rotate the articulation and block stop without the need for specific welding.

Otra mejora concierne la unión de los pies en las dos articulaciones que, gracias a la posición de su eje de rotación, permite a los dos pies superponerse completamente cuando están plegados; asentándose perfectamente el conjunto de los dos pies en la prolongación de la articulación con el fin de obtener una compacidad de plegado ideal. Another improvement concerns the union of the feet in the two joints that, thanks to the position of its axis of rotation, allows the two feet to completely overlap when folded; perfectly set the whole of the two feet in the extension of the joint in order to obtain an ideal folding compactness.

Otra mejora reside en la forma de bisel de la extremidad superior de los pies que, situados en la articulación, permite Another improvement lies in the bevel shape of the upper extremity of the feet that, located in the joint, allows

obtener un tope muy sólido y sin juego cuando los pies están desplegados y el caballete cargado. Otra mejora concierne la apertura de estos cuatro pies que es realizada mediante un muelle que atraviesa los pies y que está dimensionado para escamotearse completamente en los pies cuando éstos se repliegan con el fin de evitar por tanto un sobre-espesor. get a very solid and no play stop when the feet are deployed and the stand is loaded. Another improvement concerns the opening of these four feet that is made by a pier that crosses the feet and which is sized to completely retrace the feet when they fold in order to avoid therefore an over-thickness.

La última mejora concierne al sistema que hace solidarias las dos traviesas conjuntamente lado a lado por medio de la combinación de dos formas cooperantes con una extremidad de traviesas y un tetón que penetra en la segunda traviesa en la otra extremidad; estando el conjunto bloqueado de forma muy segura mediante la utilización de uno de los dos bloqueos de articulación al que se ha añadido un gancho. The last improvement concerns the system that supports the two sleepers together side by side through the combination of two cooperating forms with a sleeper limb and a bumper that penetrates the second naughty on the other end; the assembly being locked very securely by using one of the two articulation locks to which a hook has been added.

Figure 11 represents the second end of the sleepers after assembly. Figure 12 depicts a side view of the assembled stands to show the release system. of the easels.

La figura 13 representa una vista del interior de un caballete plegado. Según la figura 1, el caballete está compuesto por una traviesa (1), dos articulaciones (2) (3) y dos pares de pies (4) (4’) y (5) (5’). Las dos articulaciones (2) (3) pivotan alrededor de ejes de rotación (7) (7’) perpendiculares a la traviesa Figure 13 represents a view of the inside of a folded stand. According to figure 1, the easel is composed of a sleeper (1), two joints (2) (3) and two pairs of feet (4) (4 ’) and (5) (5’). The two joints (2) (3) pivot around axes of rotation (7) (7 ’) perpendicular to the crossbar

(1). Los pares de pies (4) (4’) y (5) (5’) pivotan alrededor de los ejes (9) (9’) solidarios perpendicularmente a las articulaciones (2) (3). (one). The pairs of feet (4) (4 ’) and (5) (5’) pivot around the axes (9) (9 ’) in solidarity perpendicular to the joints (2) (3).

Según la figura 2, las articulaciones (2) (3) y los pies (4) (4’) y (5) (5’) están totalmente escamoteados en el perfil de la traviesa (1). El conjunto forma un perfil rectangular y compacto. According to figure 2, the joints (2) (3) and the feet (4) (4 ’) and (5) (5’) are fully retracted in the profile of the sleeper (1). The set forms a rectangular and compact profile.

Las figuras 2 y 3 muestran también la diferencia entre las dos articulaciones (2) (3). Para permitir una compacidad creciente y la superposición de los dos pares de pies (4) (4’) y (5) (5’), una de las articulaciones, aquí la articulación (2), tiene su eje de rotación (7) descentrado respecto del plano horizontal formado por la unión de dos pies (4) (4’) pero permanece alineado con el segundo eje de rotación (7’) para garantizar el bloqueo. Para ello, la pared de la articulación (2) en contacto con el bloqueo (6) durante el estado abierto se sitúa al mismo nivel horizontal que la misma pared de la articulación (3). Figures 2 and 3 also show the difference between the two joints (2) (3). To allow increasing compactness and the superposition of the two pairs of feet (4) (4 ') and (5) (5'), one of the joints, here the joint (2), has its axis of rotation (7) offset from the horizontal plane formed by the union of two feet (4) (4 ') but remains aligned with the second axis of rotation (7') to ensure blockage. To do this, the wall of the joint (2) in contact with the lock (6) during the open state is positioned at the same horizontal level as the same wall of the joint (3).

Según las figuras 1, 2, 3 y 4 el usuario puede desplegar la articulación (3) presionando sobre el tetón (22) solidario de la articulación (3). Las dos articulaciones (2) (3) y los pares de pies (4) (4’) y (5) (5’) pivotan de los ejes de rotación (7) (7’) gracias a su propio peso y hacen tope respectivamente sobre (17) (17’). El bloqueo se realiza entonces mediante cerrojos (6) (6’) que estaban alojados e inmovilizados bajo las articulaciones (2) (3) en posición plegadas y que son liberados durante la rotación de las articulaciones (2) (3). Éste movimiento de rotación de los cerrojos (6) (6’) alrededor de los ejes (12) (12’) está provocado por los dos muelles (19) (19’) que toman apoyo sobre la cara interior y superior de la traviesa (1) y empuja los dos cerrojos (6) (6’). Los puntos de apoyo (27) (27’) de los cerrojos (6) (6’) sobre las articulaciones (2) (3) se alinean sobre las rectas horizontales simbolizadas en sus extremidades mediante los topes (17) (17’) y los ejes (12) (12’). Estos alineamientos confieren a las articulaciones un bloqueo irreversible. Para plegar los conjuntos de articulaciones (2) (3) con sus pies (4) (4’) y (5) (5’), hace falta entonces presionar sobre los cerrojos (6) (6’) a nivel de sus extremidades respectivas (24) (24’) para hacer pivotar estos cerrojos (6) (6’) alrededor de sus ejes (12) (12’). Esto permite entonces la liberación de las articulaciones y su plegado en la traviesa (1). According to figures 1, 2, 3 and 4 the user can deploy the joint (3) by pressing on the joint (22) integral with the joint (3). The two joints (2) (3) and the pairs of feet (4) (4 ') and (5) (5') pivot of the rotation axes (7) (7 ') thanks to their own weight and stop respectively on (17) (17 '). The blocking is then carried out by means of bolts (6) (6 ’) that were housed and immobilized under the joints (2) (3) in the folded position and that are released during the rotation of the joints (2) (3). This rotational movement of the bolts (6) (6 ') around the shafts (12) (12') is caused by the two springs (19) (19 ') that take support on the inner and upper side of the crossbar (1) and push the two bolts (6) (6 '). The support points (27) (27 ') of the bolts (6) (6') on the joints (2) (3) are aligned on the horizontal straight lines symbolized at their extremities by means of the stops (17) (17 ') and the axes (12) (12 '). These alignments give the joints an irreversible block. To fold the joint assemblies (2) (3) with their feet (4) (4 ') and (5) (5'), then it is necessary to press on the bolts (6) (6 ') at the level of their extremities respective (24) (24 ') to swing these bolts (6) (6') around their axes (12) (12 '). This then allows the release of the joints and their folding in the crossbar (1).

Las figuras 2 y 3 muestran que, para realizar el tope con fin de carrera de la articulación (2), se recorta un recorte Figures 2 and 3 show that, to make the stop with end of stroke of the joint (2), a cut is cut

(16) que tiene como centro, el eje de rotación (7). El final de este recorte (16) se apoya sobre el tope (17) en posición desplegado. (16) whose center of rotation is the axis of rotation (7). The end of this cutout (16) rests on the stop (17) in the deployed position.

Según las figuras 5 y 6, el despliegue de los pies (4) (4’) y (5) (5’) se realiza alrededor de ejes (9) (9’) solidarios a las articulaciones (2) (3). Cuando las articulaciones (2) (3) se despliegan fuera de la traviesa (1), los pies (4) (4’) (5) (5’) se despliegan pivotando alrededor de los ejes (9) (9’) bajo la acción de los muelles (8) (8’). La posición final se obtiene mediante las extremidades superiores (25) (25’) biseladas de los pies (4) (4’) y (5) (5’) que se apoyan sobre la pared interior de las articulaciones (2) (3). Durante su plegado, los muelles (8) (8’) se escamotean completamente en los pies (4) (4’) y (5) (5’) permitiendo obtener una superposición de estos últimos que forman entonces una sección (20) que se inscribe en la sección (21) definida por las articulaciones (2) (3). Esto confiere una compacidad que permite plegar las articulaciones (2) (3) y los pies (4) (4’) y (5) (5’) en el perfil de la traviesa (1). According to figures 5 and 6, the deployment of the feet (4) (4 ’) and (5) (5’) is carried out around axes (9) (9 ’) integral to the joints (2) (3). When the joints (2) (3) are deployed outside the crossbar (1), the feet (4) (4 ') (5) (5') are deployed pivoting around the shafts (9) (9 ') under the action of the springs (8) (8 '). The final position is obtained by the upper extremities (25) (25 ') beveled of the feet (4) (4') and (5) (5 ') that rest on the inner wall of the joints (2) (3 ). During its folding, the springs (8) (8 ') are completely retracted on the feet (4) (4') and (5) (5 ') allowing to obtain an overlap of the latter that then form a section (20) that it is inscribed in section (21) defined by the joints (2) (3). This confers a compactness that allows the joints (2) (3) and the feet (4) (4 ’) and (5) (5’) to be folded into the profile of the sleeper (1).

La figura 7 muestra las traviesas (1) (1’) ensambladas lado a lado. Figure 7 shows the sleepers (1) (1 ’) assembled side by side.

Las figuras 8, 9, 10 y 11 describen las extremidades de las traviesas (1) (1’). Para realizar el ensamblaje el usuario inserta el recorte (15) de la traviesa (1’) en el canal (14) de la traviesa (1). Después de haber ensamblado de esta forma estos dos extremidades de las traviesas (1) (1’) y después de haber elevado el gancho (11) del cerrojo (6’), el usuario bloquea las otras dos extremidades de dichas traviesas (1) (1’) introduciendo el tetón (13) del eje (12’) del cerrojo (6’) de la traviesa (1) en un alojamiento (18) de la traviesa (1). Figures 8, 9, 10 and 11 describe the ends of the sleepers (1) (1 ’). To assemble the user inserts the cutout (15) of the crossbar (1 ’) into the channel (14) of the crossbar (1). After having assembled in this way these two ends of the sleepers (1) (1 ') and after having raised the hook (11) of the bolt (6'), the user blocks the other two ends of said sleepers (1) (1 ') by inserting the pin (13) of the shaft (12') of the bolt (6 ') of the crossbar (1) into a housing (18) of the crossbar (1).

Según las figuras 2, 10 y 11, el cerrojo (6’) es levantado para que el gancho (11 ) ligado a este cerrojo no moleste el adosamiento de las dos traviesas (1) (1’). Cuando entran en contacto, el cerrojo (6’) es liberado y empujado por el muelle (19’) que va a arrastrar el gancho (11), que va a inmovilizar las dos traviesas impidiendo que el tetón (13) salga del alojamiento (18). El par de traviesas se hace pues solidario. According to figures 2, 10 and 11, the bolt (6 ’) is lifted so that the hook (11) attached to this bolt does not disturb the attachment of the two sleepers (1) (1’). When they come into contact, the bolt (6 ') is released and pushed by the spring (19') that is going to drag the hook (11), which will immobilize the two sleepers preventing the pin (13) from leaving the housing ( 18). The pair of sleepers becomes solidarity.

Las figuras 1, 7, 12 y 13 permiten mostrar el sistema de liberación automático de las articulaciones (2) (3). Un tetón Figures 1, 7, 12 and 13 show the automatic joint release system (2) (3). A big tit

(22) solidario a un muelle (26) y deslizante en la articulación (3) va a un recorte (23) de la traviesa (1). Para liberar los pies, el usuario mantiene la traviesa horizontal del lado abierto hacia el suelo y presiona sobre el tetón (22) que se hunde en la articulación (3) y permite a esta última girar alrededor del eje de rotación (7’) mediante gravedad. (22) attached to a spring (26) and sliding in the joint (3) goes to a cutout (23) of the crossbar (1). To release the feet, the user keeps the horizontal crossbar from the open side towards the ground and presses on the pin (22) that sinks into the joint (3) and allows the latter to rotate around the axis of rotation (7 ') by gravity.
