Description

Caballete multiuso.Multi-purpose stand

Objeto de la invenciónObject of the invention

La presente invención se refiere a un caballete, del tipo de los que se materializan en una columna rematada inferiormente en un trípode y superiormente en un cabezal, que a través de dicho cabezal cumple su función como tal elemento de apoyo, convenientemente distanciado del suelo.The present invention relates to an easel, of the kind that materialize in a topped column inferiorly on a tripod and superiorly on a head, which at through said head it fulfills its function as such an element of support, conveniently distanced from the ground.

El caballete constituye una herramienta de gran resistencia y fácil transporte, que cuenta con múltiples aplicaciones tales como la sustentación de rótulos, tubos, vigas, techos prefabricados, muebles, etc, pudiendo actuar también como prensor de suelo a techo o de pared a pared, etc.The easel is a great tool Resistance and easy transport, which has multiple applications such as the support of signs, tubes, beams, prefabricated ceilings, furniture, etc., and can also act as floor to ceiling or wall to wall presser, etc.

El objeto de la invención es conseguir un caballete de altura regulable, dotado de medios de nivelación y con una gran facilidad de adaptación o adecuación a cualquier exigencia práctica derivada de las diferentes utilidades previstas para el mismo.The object of the invention is to achieve a height adjustable stand, equipped with leveling means and with a great ease of adaptation or adaptation to any requirement practice derived from the different utilities planned for the same.

Antecedentes de la invenciónBackground of the invention

Los caballetes existentes en la actualidad se materializan en un trípode inferior del que emerge una columna telescópica rematada en una pequeña superficie de apoyo, de manera que estos caballetes traen consigo una notable limitación aplicativa, ya que están concebidos fundamentalmente como puntales.The easels currently available are they materialize on a lower tripod from which a column emerges telescopic topped on a small support surface, so that these easels bring with them a notable limitation application, since they are primarily conceived as props

Los caballetes concebidos como elementos sustentadores son dobles, es decir, repiten la estructura citada, relacionándose sus dos mitades mediante travesaños, lo que complica considerablemente su estructura y dificulta también de forma muy considerable su manejo dada su volumetría, por lo que habitualmente, en estos casos se utilizan dos caballetes independientes, relacionados entre sí mediante un travesaño superior desmontable, que constituye el medio de apoyo para los objetos a sustentar. Esta solución simplifica sensiblemente los problemas de manipulación, pero sin embargo, sigue suponiendo una notable complejidad estructural para el caballete doble, y una ocupación de espacio que en muchos casos resulta inaceptable.Easels conceived as elements Sustainers are double, that is, they repeat the structure cited, relating its two halves through crossbars, which complicates considerably its structure and also makes it very difficult considerable handling given its volumetry, so usually, in these cases two easels are used independent, interrelated by means of a top crossbar  detachable, which is the support for objects to sustain, support. This solution significantly simplifies the problems of manipulation, but nevertheless, it is still a remarkable structural complexity for the double stand, and an occupation of space that in many cases is unacceptable.

Además, cualquiera de los caballetes anteriormente citados presenta problemas de nivelación en el plano de carga.Also, any of the easels previously mentioned presents leveling problems in the plane loading

Descripción de la invenciónDescription of the invention

El caballete que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta.The easel that the invention proposes resolves from the problem was fully satisfactory before exposed.

Para ello y de forma más concreta el caballete que se preconiza, provisto de una columna telescópica rematada inferiormente en un trípode de apoyo, por ejemplo sobre el suelo, presenta su extremidad superior y libre rematada en una pletina transversal, que se fija al tubo participante en dicha columna telescópica por su punto medio, y que se remata por sus extremos en sendos tornillos reguladores, paralelos y verticales, dotados de respectivas manetas de accionamiento, de manera que en el caballete se definen dos zonas de apoyo sustancialmente distanciadas, de posicionamiento en altura regulable para asegurar una perfecta nivelación. En este sentido y de acuerdo con una variante de realización de la invención, la citada pletina puede rematarse a su vez en otras dos pletinas transversales y paralelas, que reciben por sus extremos a sendos tornillos reguladores, en cuyo caso el caballete ofrece cuatro puntos de apoyo regulables, situados según los imaginarios vértices de un cuadrilátero.For this and more specifically the easel which is recommended, provided with a telescopic column topped inferiorly on a support tripod, for example on the ground, presents its upper and free limb topped on a plate transverse, which is fixed to the participant tube in said column telescopic by its midpoint, and that is topped by its ends in two regulating screws, parallel and vertical, equipped with respective drive handles, so that on the easel two substantially spaced support areas are defined, of height-adjustable positioning to ensure perfect leveling In this regard and according to a variant of embodiment of the invention, said plate can be finished off once in two other transversal and parallel plates, which are received by its ends to two regulating screws, in which case the easel offers four adjustable support points, located according to the imaginary vertices of a quadrilateral.

La columna telescópica está constituida, como es convencional, mediante dos o más tubos cilíndricos y coaxiales, uno solidario a la pletina que forma parte del cabezal superior y otro al trípode inferior, que son fijados entre sí mediante dos pomos que rematan respectivos tornillos prisioneros, de manera que esta doble fijación, además de asegurar la inmovilización entre los dos tubos que participan en la columna telescópica, permite fijar convenientemente dichos tubos, en situación de desacoplamiento total de uno con respecto al otro, cuando es necesario incrementar en mayor medida la altura efectiva del caballete, mediante la utilización de un tubo alargador, con un casquillo intermedio, provisto a su vez de otros dos prisioneros con sus respectivos pomos.The telescopic column is constituted, as it is conventional, by means of two or more cylindrical and coaxial tubes, one solidarity with the plate that is part of the upper head and other to the lower tripod, which are fixed together by two knobs that finish off respective captive screws, so that this double fixation, in addition to ensuring the immobilization between the two tubes that participate in the telescopic column, allows fixing conveniently said tubes, in a situation of total decoupling of one with respect to the other, when it is necessary to increase in greater measure of the effective height of the easel, through use of an extension tube, with an intermediate bushing, provided in turn with two other prisoners with their respective knobs

Se ha previsto también la disposición, inmediatamente por encima del trípode, es decir, donde se inicia la columna propiamente dicha, de un tope discoidal, coaxial con la propia columna, del que emerge lateralmente un pasador desmontable, estando dicho tope destinado a recibir opcionalmente a una pluralidad de contrapesos, asimismo discoidales, con un corte radial para su acoplamiento lateral en la columna, y con un orificio operativamente enfrentado al citado pasador, para definitiva retención de tales contrapesos, los cuales tienen como evidente finalidad desplazar sustancialmente hacia abajo el centro de gravedad del caballete, con su carga, para potenciar su estabilidad en aquellos casos en los que el cabezal se sitúa a gran altura.The provision is also planned, immediately above the tripod, that is, where the column itself, of a discoidal stop, coaxial with the own column, from which a detachable pin emerges laterally, said stop being intended to optionally receive a plurality of counterweights, also discoidal, with a radial cut for lateral coupling in the column, and with a hole operatively faced with the aforementioned pin, for definitive retention of such counterweights, which are evident purpose of substantially shifting the center of gravity of the easel, with its load, to enhance its stability in those cases in which the head is placed at high altitude.

De acuerdo con otra de las características de la invención se ha previsto que el caballete propiamente dicho esté asistido por una serie de adaptadores que adecuan su estructura a diferentes aplicaciones prácticas, concretamente un listón de madera u otro material, acoplable a la pareja de tornillos reguladores, que forman el cabezal actuando como aislante y evitando que el objeto a colocar, de base plana, apoye directamente sobre dichos tornillos reguladores y pueda resultar dañado por los mismos, especialmente cuando se trata de objetos delicados. Existe otro adaptador acoplable de igual manera que el anterior y con su base superior diédrica, es decir, una base de asiento angular para estabilización de objetos de sección circular. También se ha previsto la adaptación al cabezal de un rodillo, con medios de freno o bloqueo, que resulta especialmente idóneo cuando el objeto a colocar debe ser desplazado lateralmente una vez que se ha alcanzado la altura deseada.According to another of the characteristics of the invention it is provided that the stand itself is assisted by a series of adapters that adapt their structure to different practical applications, specifically a ribbon of wood or other material, attachable to the pair of screws regulators, which form the head acting as an insulator and avoiding  that the object to be placed, with a flat base, rest directly on said regulating screws and may be damaged by the themselves, especially when it comes to delicate objects. Exists another adapter attachable in the same way as the previous one and with its upper dihedral base, that is, an angular seat base for stabilization of objects of circular section. It has also provided for adaptation to the head of a roller, with brake means or blocking, which is especially suitable when the object is place must be displaced laterally once it has been reached the desired height.

Todos estos adaptadores pueden tener exclusivamente alojamientos en su base para los tornillos reguladores, o bien pueden incorporar además prolongaciones ranuradas en funciones de encaje para el borde superior de la pletina del cabezal.All these adapters can have exclusively housings in its base for the screws regulators, or they can also incorporate extensions grooved in lace functions for the upper edge of the head plate.

Por último se ha previsto también que la extremidad libre de los brazos que participan en el trípode quede encajada en bases de madera u otro material, con un revestimiento inferior de goma u otro material blando para evitar el deterioro de superficies delicadas sobre las que deba apoyar el caballete. Además, se ha previsto también que uno de los brazos del trípode esté dotado de medios de regulación en altura, para permitir un perfecto aplomo de la columna cuando existan desniveles en la superficie de apoyo.Finally, it is also foreseen that the free limb of the arms that participate in the tripod is embedded in bases of wood or other material, with a coating rubber bottom or other soft material to prevent deterioration of delicate surfaces on which the easel should rest. In addition, it is also planned that one of the tripod arms is equipped with height adjustment means, to allow a perfect poise of the spine when there are unevenness in the support surface.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de las figuras reseñadas y más concretamente de la figura 1, puede observarse como el caballete multiuso que la invención propone está constituido a partir de una columna telescópica en la que participan al menos dos tubos (1) y (2), rematada inferiormente en un trípode (3) y superiormente en un cabezal (34), estando el tubo telescópico inferior (1), provisto, cerca de su extremidad superior, de una pareja de tuercas (5) debidamente fijadas al mismo, para paso de respectivos tornillos prisioneros (6) que atacan radialmente al tubo (2), para su fijación, y que están asistidos por respectivos pomos (7) que facilitan su accionamiento manual.In view of the figures outlined and more specifically from figure 1, it can be seen as the easel multipurpose that the invention proposes is constituted from a telescopic column in which at least two tubes (1) participate and (2), topped off on a tripod (3) and top on a head (34), the lower telescopic tube (1) being provided, near its upper extremity, a pair of nuts (5) duly fixed to it, for the passage of respective screws prisoners (6) that radially attack the tube (2), for fixing, and that are assisted by respective knobs (7) that They facilitate manual operation.

Los brazos del trípode (3) se rematan en sendas bases de madera u otro material (8), una de ellas asistida por un tornillo de regulación (9), para una correcta nivelación del conjunto y consecuente aplomo de la columna (1- 2), bases de madera u otro material (8) preferentemente con su cara inferior dotada de un revestimiento de goma u otro material blando, que proteja convenientemente la superficie de apoyo del caballete.The tripod arms (3) are finished off in paths bases of wood or other material (8), one of them assisted by a adjustment screw (9), for proper leveling of the set and consequent aplomb of the column (1-2), wooden bases or other material (8) preferably with its lower face provided with a rubber coating or other soft material, which protects conveniently the support surface of the easel.

El cabezal (34) se materializa en la pletina transversal, que se corresponde con la referencia (4), convenientemente solidarizada a la extremidad superior del tubo (2) que participa en la columna, pletina (4) rematada en sendos tornillos reguladores (10), verticales, en disposición simétrica con respecto al tubo (2) y asistidos por correspondientes manetas (11) de accionamiento de los mismos, de manera que el disco frontal (12) de tales tornillos reguladores (10) constituye la zona de apoyo sobre el caballete, consecuentemente en dos puntos sustancialmente distanciados.The head (34) materializes on the plate transverse, which corresponds to reference (4), conveniently in solidarity with the upper end of the tube (2) participating in the column, plate (4) finished off in two regulating screws (10), vertical, in symmetrical arrangement with respect to the tube (2) and assisted by corresponding handles (11) driving them, so that the front disk (12) of such regulating screws (10) constitutes the area of stand on the easel, consequently in two points substantially distanced.

Existe no obstante la posibilidad mostrada en la figura 2 de que la pletina (4) se remate en una pareja de pletinas transversales (4'), rematadas a su vez en cuatro tornillos reguladores (10), constituyendo todo ello el cabezal (35), lo que equivale a la existencia en el caballete de cuatro puntos de apoyo distribuidos según los imaginarios vértices de un cuadrilátero.There is, however, the possibility shown in the Figure 2 that the plate (4) is shot in a pair of plates transverse (4 '), finished in turn with four screws regulators (10), all of which constitutes the head (35), which it is equivalent to the existence of four support points on the easel distributed according to the imaginary vertices of a quadrilateral.

La cota en altura que pueden alcanzar los citados apoyos (12) viene derivada de la longitud de los tubos telescópicos (1) y (2), y la pareja de los tornillos prisioneros (6) para fijación de dichos tubos tiene como finalidad, además de potenciar dicha fijación, permitir la utilización opcional de al menos un tubo alargador (13), intermedio, que se fija por uno de sus extremos al tubo inferior (1) y que por su otro extremo recibe, con la colaboración de un casquillo (14), con un tope (15), al tubo (2) del cabezal, con la colaboración de otra pareja de tornillos prisioneros (6'), como se observa en la figura 6.The height that can be reached supports (12) is derived from the length of the telescopic tubes (1) and (2), and the pair of the captive screws (6) for fixation of said tubes is also intended to enhance said fixation, allow the optional use of at least one extension tube (13), intermediate, which is fixed at one end  to the lower tube (1) and that at its other end receives, with the collaboration of a bushing (14), with a stop (15), to the tube (2) of the head, with the collaboration of another pair of screws prisoners (6 '), as seen in figure 6.

La extremidad inferior de la columna, es decir, la extremidad inferior del tubo inferior (1), inmediatamente por encima del trípode (3), recibe a un tope discoidal (16) rígidamente fijado a dicha columna, del que emerge superiormente y en situación marginal un pasador desmontable (17) de reducido diámetro, paralelo a la propia columna, estando dicho tope (16) destinado a recibir a uno o más contrapesos (18), como el mostrado en la figura 7, a su vez de configuración discoidal, con un corte diametral (19) para permitir su acoplamiento lateral a la columna (1), y con un orificio (20) para acoplamiento del pasador desmontable (17), que inmoviliza el contrapeso (18) una vez que éste ha alcanzado la situación límite de apoyo sobre el tope (16) o sobre un contrapeso intermediamente inferior, teniendo estos contrapesos la finalidad ya comentada de dotar de mayor estabilidad al caballete, especialmente cuando sus cabezales (34) (35) se sitúan a mucha altura.The lower extremity of the spine, that is, the lower extremity of the lower tube (1), immediately by on top of the tripod (3), receive a hard disk (16) rigidly fixed to said column, from which it emerges superiorly and in situation marginal a detachable pin (17) of reduced diameter, parallel to the column itself, said stop (16) intended to receive one or more counterweights (18), as shown in Figure 7, at its time of discoidal configuration, with a diametral cut (19) for allow its lateral coupling to the column (1), and with a hole (20) for detachable pin coupling (17), which immobilizes the counterweight (18) once it has reached the situation support limit on the stop (16) or on a counterweight intermediate lower, these weights having the purpose already commented on providing more stability to the easel, especially when their heads (34) (35) are placed a lot height.

Los cabezales (34) y (35), si bien pueden actuar directamente como elemento sustentador a través de los tornillos reguladores (10), y más concretamente en sus bases discoidales (12), pueden hacerlo con interposición de diferentes adaptadores, los mostrados en las figuras 3 a 5. Concretamente en la figura 3, a través de un adaptador (21) materializado en un listón de madera u otro material, provisto en su cara inferior de alojamientos cilíndricos (22) para acoplamiento de las citadas bases discoidales (12) de los tornillos reguladores (10), listón de madera u otro material, prismático-rectangular, que no hace más que ofrecer un apoyo plano y continuo para los objetos a depositar sobre el caballete. Un segundo tipo de adaptador consiste a su vez una pieza (23) cuya cara o borde superior (24) configura un diedro obtuso, especialmente idóneo para apoyar sobre el caballete, en lugar de objetos con una base plana, objetos cilíndricos que puedan tender a la rodadura lateral y dotado en su base inferior de alojamientos (22') similares a los alojamientos (22) del caso anterior y con la misma
finalidad.The heads (34) and (35), although they can act directly as a support element through the regulating screws (10), and more specifically in their discoid bases (12), can do so with interposition of different adapters, those shown in Figures 3 to 5. Specifically in Figure 3, through an adapter (21) materialized in a slat of wood or other material, provided on its lower face with cylindrical housings (22) for coupling the said discoidal bases (12 ) of the regulating screws (10), wooden strip or other prismatic-rectangular material, which only offers a flat and continuous support for the objects to be deposited on the easel. A second type of adapter in turn consists of a piece (23) whose face or upper edge (24) configures an obtuse dihedral, especially suitable for resting on the stand, instead of objects with a flat base, cylindrical objects that can tend to the lateral rolling and endowed in its lower base of housings (22 ') similar to the housings (22) of the previous case and with the same
purpose

En determinados supuestos prácticos puede darse la circunstancia de que el objeto a ubicar sobre el caballete, una vez alcanzado el nivel en altura adecuado, deba ser desplazado transversalmente, en cuyo caso se ha previsto el adaptador mostrado en la figura 5, en el que sobre una plataforma plana (25) se establecen dos tabiques paralelos (26) sobre los que se monta con libertad de giro el eje de un rodillo (27), que constituye el verdadero elemento de apoyo que permite tal desplazamiento lateral, quedando dicho rodillo (27) enmarcado por dos bloques prismáticos-laterales (28) en los que se establecen respectivos elementos de freno materializados en sendos prisioneros (29), con sus respectivos pomos (30), encargados de bloquear el rodillo para anular funcionalmente al mismo una vez que el objeto situado sobre él ha adoptado la posición correcta.In certain practical cases it can occur the circumstance that the object to be placed on the easel, a Once you have reached the appropriate height level, it must be moved transversely, in which case the adapter shown is provided in figure 5, in which on a flat platform (25) establish two parallel partitions (26) on which it is mounted with freedom of rotation the axis of a roller (27), which constitutes the true support element that allows such lateral displacement, said roller (27) being framed by two blocks side-binoculars (28) in which they are set respective brake elements materialized in two prisoners (29), with their respective knobs (30), responsible for blocking the roller to functionally override it once the object located above it has taken the right position.

En este caso, en la plataforma base (25) se establecerán protuberancias (31) con alojamientos (22'') para los apoyos discoidales (12) de los tornillos reguladores (10), habiéndose previsto que en cualquiera de los casos anteriormente citados los adaptadores puedan incorporar además prolongaciones inferiores (32), con respectivas ranuras (33) para su acoplamiento a las pletinas (4) ó (4') de los cabezales (34) ó (35).In this case, on the base platform (25) you they will establish bumps (31) with housings (22 '') for the discoidal supports (12) of the regulating screws (10), having anticipated that in any of the cases previously cited adapters may also incorporate extensions lower (32), with respective grooves (33) for coupling to the plates (4) or (4 ') of the heads (34) or (35).

El carácter cambiable de estos adaptadores (21), (23) y (25) potencia de forma muy considerable la funcionalidad del caballete.The changeable nature of these adapters (21), (23) and (25) greatly enhance the functionality of the easel.
