Description

OBJETO DE LA INVENCiÓN OBJECT OF THE INVENTION

La presente invención se refiere a un dispositivo que ha sido especialmente concebido para conseguir de una forma rápida y sencilla una perfecta nivelación de cualquier objeto apoyado sobre patas, así como una fijación o estabilización en tal posición. The present invention relates to a device that has been specially designed to quickly and easily achieve a perfect leveling of any object supported on legs, as well as a fixation or stabilization in such position.

La invención resulta particularmente aplicable a mesas, escaleras portátiles, andamios, plataformas de todo tipo y en general a todos aquellos objetos que utilicen patas como elemento de apoyo. The invention is particularly applicable to tables, portable stairs, scaffolding, platforms of all kinds and in general to all those objects that use legs as a support element.

El dispositivo de la invención permite compensar acusados desniveles existentes en el suelo The device of the invention makes it possible to compensate for marked unevenness in the ground

o superficie de apoyo, adoptando el objeto apoyado sobre tal dispositivo una perfecta nivelación en sentido horizontal y/o vertical. or support surface, adopting the object resting on such a device a perfect leveling horizontally and / or vertically.

ANTECEDENTES DE LA INVENCiÓN BACKGROUND OF THE INVENTION

La mayor parte de los objetos destinados a apoyar sobre el suelo a través de patas, ya sea a través de dos, cuatro o mas de tales patas, están estructurados de manera que la extremidad inferior de tales patas está incluida en un imaginario plano horizontal, por lo que su apoyo solo resulta adecuado cuando el suelo es a su vez perfectamente horizontal, lo que en la práctica no sucede en la mayoría de las ocasiones, lo que hace que el objeto quede "cojo", con posibilidad de basculación, lo que causa a su vez que el posicionamiento sea inestable. Para solventar este problema se utilizan habitualmente calzos que se introducen entre pata y suelo, calzos que deben presentar un grosor específico en cada caso y que hacen que el apoyo resulte poco seguro con el consiguiente riesgo de accidentes mas o menos graves. Most of the objects intended to rest on the ground through legs, whether through two, four or more of such legs, are structured such that the lower extremity of such legs is included in an imaginary horizontal plane, so that its support is only adequate when the ground is in turn perfectly horizontal, which in practice does not happen in most cases, which makes the object "lame", with the possibility of tilting, which cause in turn that the positioning is unstable. To solve this problem, chocks are usually used that are inserted between the legs and the ground, shims that must have a specific thickness in each case and that make the support unsafe with the consequent risk of more or less serious accidents.

Tratando de obviar este problema es conocida la utilización de tornillos reguladores que se sitúan como prolongación inferior de las patas y que constituyen los apoyos del objeto sobre el suelo. Sin embargo esta solución resulta extraordinariamente lenta y de difícil manipulación cuando, con el tiempo, se produce un ensuciamiento que dificulta el movimiento de rosca, como por ejemplo en el caso de objetos utilizables en obras, donde sobre los mismos caen pegotes de yeso u otros materiales que se adhieren a los citados tornillos. Además las posibilidades de regulación de estos dispositivos roscados resulta muy corta, de manera que resultan inutilizables en determinados casos, como por ejemplo el de una escalera portátil que en un determinado momento debe apoyar sobre dos escalones de una escalera de obra, con evidente y acusada diferencia de altura sobre los planos de apoyo. Trying to obviate this problem it is known to use regulating screws that are located as a lower extension of the legs and that constitute the supports of the object on the ground. However, this solution is extraordinarily slow and difficult to handle when, over time, fouling occurs that hinders the movement of thread, as for example in the case of objects that can be used in works, where plaster sticks or others fall on them. materials that adhere to the aforementioned screws. In addition the possibilities of regulation of these threaded devices is very short, so that they are unusable in certain cases, such as that of a portable staircase that at a given moment must rest on two steps of a ladder, with obvious and pronounced height difference over the support planes.

DESCRIPCiÓN DE LA INVENCiÓN DESCRIPTION OF THE INVENTION

El dispositivo nivelador-estabilizador que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, consiguiendo una perfecta nivelación y estabilización del objeto de que se trate, con una estructura simple, altamente eficaz y de rápida manipulación. The leveling-stabilizing device that the invention proposes solves in a fully satisfactory manner the above-mentioned problem, achieving a perfect leveling and stabilization of the object in question, with a simple structure, highly effective and quickly manipulated.

De forma mas concreta el dispositivo en cuestión, que puede estar integrado en el objeto de que se trate o constituir un complemento adaptable al mismo, se materializa en un émbolo hidráulico para cada pata, estando los diferentes émbolos relacionados entre si mediante un circuito hidráulico que los intercomunica, circuito en el que se establece una llave de paso fácilmente accesible, de manera que cuando dicha llave está abierta los émbolos pueden bajar y subir libremente hasta conseguir una perfecta nivelación del objeto, momento en el que el cierre de la citada llave supone la rigidización de todos y cada uno de los émbolos, con la consecuente fijación y estabilización del objeto de que se trate con respecto al suelo. More specifically, the device in question, which may be integrated in the object in question or constitute an adaptable complement thereto, is embodied in a hydraulic piston for each leg, the different pistons being related to each other by means of a hydraulic circuit that the intercoms, a circuit in which an easily accessible stopcock is established, so that when said key is open the pistons can go down and up freely until a perfect leveling of the object is achieved, at which time the closing of said key supposes the stiffening of each and every one of the pistons, with the consequent fixation and stabilization of the object in question with respect to the ground.

REALIZACiÓN PREFERENTE DE LA INVENCiÓN PREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas y en particular de la figura 1, puede observarse como el dispositivo que la invención propone está constituido a partir de soportes verticales (1, 1 '), que pueden quedar integrados en la estructura del objeto de que se trate, por ejemplo formando parte de sus patas, o que pueden constituir un accesorio adaptable al objeto en cuestión. Estos dos soportes verticales se rematan por su extremidad inferior en sendas cámaras (2, 2') en las que juegan respectivos émbolos hidráulicos (3, 3'), que constituyen los elementos de apoyo real sobre el suelo (4). Las diferentes cámaras (2, 2') están relacionadas entre si mediante un circuito hidráulico (5) que se asocia tanto con los soportes verticales (1) como a un travesaño (6) que relaciona tales soportes, estableciéndose en el lugar mas apropiado de dicho circuito hidráulico (5), el mas fácilmente accesible, una llave In view of the figures outlined and in particular of Figure 1, it can be seen how the device proposed by the invention is constituted from vertical supports (1, 1 '), which can be integrated into the structure of the object of which try, for example, as part of their legs, or which may constitute an accessory that is adaptable to the object in question. These two vertical supports are topped by their lower extremity in two chambers (2, 2 ') in which respective hydraulic pistons (3, 3') play, which constitute the real support elements on the ground (4). The different chambers (2, 2 ') are related to each other by means of a hydraulic circuit (5) that is associated with both the vertical supports (1) and a crossbar (6) that relates such supports, establishing themselves in the most appropriate place of said hydraulic circuit (5), the most easily accessible, a key

(7) capaz de mantener las diferentes ramas del circuito (5) intercomunicadas, o unitariamente aisladas. (7) able to keep the different branches of the circuit (5) intercommunicated, or unitary isolated.

De acuerdo con esta estructuración, cuando la llave (7) está abierta los émbolos (3, 3') pueden subir y bajar pasando el aceite de unos a otros, hasta conseguir una perfecta nivelación, momento en el que el cierre de la llave (7) provoca que tal nivelación quede asegurada y estabilizada en el tiempo. According to this structuring, when the key (7) is open, the pistons (3, 3 ') can rise and fall by passing the oil from one to another, until a perfect leveling is achieved, at which point the closing of the key ( 7) causes such leveling to be secured and stabilized over time.

A título ejemplo, en el caso especifico mostrado en las figuras 2 a 4, puede observarse como en una escalera portátil provista de dos patas, el dispositivo puede quedar integrado en la escalera, formando parte de dichas patas (8), relacionadas mediante los clásicos travesaños (9), de los que uno de ellos se corresponde con el travesaño (6) anteriormente citado, en el que se aloja parte del circuito hidráulico (5), en el que se establece la llave (7). Cuando la escalera apoya sobre el suelo (4) horizontal, los émbolos (3, 3') rematados en los correspondientes apoyos antideslizantes (10), emergen de los cilindros hidráulicos (2) en la misma magnitud, como muestra la figura 2, lo que hace que la escalera adopte una disposición vertical. Si por el contrario el suelo (4') adopta un plano inclinado, con cualquier inclinación, la apertura de la llave de paso (7) supone que los émbolos (3, 3') puedan desplazarse combinadamente a través del circuito hidráulico, de manera que el émbolo (3), correspondiente al apoyo mas bajo, sobresale de la cámara correspondiente (2) en mayor amplitud que el émbolo (3') lo hace de su correspondiente cámara (2'), hasta el momento crítico de que la escalera adopta una disposición perfectamente vertical, momento en el que el cierre de la llave (7) rompe la comunicación entre ambas cámaras, y los émbolos se mantienen fijos completando el desnivel generado por el plano inclinado (4'). By way of example, in the specific case shown in Figures 2 to 4, it can be observed that in a portable staircase provided with two legs, the device can be integrated in the ladder, forming part of said legs (8), related by means of the classics crossbars (9), of which one of them corresponds to the crossbar (6) mentioned above, in which part of the hydraulic circuit (5) is housed, in which the key (7) is established. When the ladder rests on the horizontal floor (4), the pistons (3, 3 ') finished off in the corresponding non-slip supports (10), emerge from the hydraulic cylinders (2) in the same magnitude, as shown in Figure 2, which makes the ladder adopt a vertical layout. If, on the other hand, the ground (4 ') adopts an inclined plane, with any inclination, the opening of the stopcock (7) means that the pistons (3, 3') can move together through the hydraulic circuit, so that the piston (3), corresponding to the lowest support, protrudes from the corresponding chamber (2) in greater amplitude than the piston (3 ') does it from its corresponding chamber (2'), until the critical moment that the ladder It adopts a perfectly vertical arrangement, at which point the closing of the key (7) breaks the communication between the two chambers, and the pistons remain fixed, completing the slope generated by the inclined plane (4 ').

Con una disposición similar para los émbolos (3, 3') Y tal como muestra la figura 4, se consigue también estabilizar la escalera en su conjunto cuando ésta apoya sobre dos peldaños (11, 11 ') de una escalera de obra. With a similar arrangement for the pistons (3, 3 ') And as shown in Figure 4, it is also possible to stabilize the staircase as a whole when it rests on two steps (11, 11') of a construction ladder.
