Definitions

  • 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.
  • 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.
  • the device of the invention makes it possible to compensate for marked unevenness in the floor or support surface, adopting the object supported on such device a perfect horizontal and / or vertical leveling.
  • 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.
  • 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.
  • Figure 1 It shows, according to a schematic representation in front elevation, a leveling-stabilizing device for objects supported on legs made in accordance with the object of the present invention.
  • Figure 2 Shows, according to a representation similar to Figure 1, a leveling-stabilizing device applied to a portable ladder, supported on a horizontal plane.
  • Figure 3 Shows a representation similar to that of Figure 2, but in which the ladder appears supported on an inclined plane.
  • Figure 4. It shows, finally, another representation similar to that of Figure 2, but in which the ladder is supported on two different steps of a ladder.
  • 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) capable of maintaining the different branches of the circuit (5) intercommunicated, or unitary isolated.
  • the pistons (3,3 ') can rise and fall by passing the oil from one to the other, 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.
  • the device in a portable staircase provided with two legs, the device can be integrated into 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.
  • 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.
  • 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 ') makes 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 ').

Abstract

La présente invention concerne un dispositif permettant d'installer de niveau et de stabiliser des objets tels que des tables, des escabeaux, des échafaudages et de manière générale des objets qui utilisent des pieds comme éléments d'appui, ledit dispositif selon l'invention étant caractérisé en ce qu'il est constitué d'au moins deux supports verticaux (1,1'), dans chacun desquels on a ménagé, au niveau de leur extrémité inférieure, une chambre hydraulique (2,2') dans laquelle se déplace un piston (3,3') qui constitue l'élément d'appui sur le sol (4), les deux chambres hydrauliques (2,2') étant reliées par un circuit hydraulique (5) pourvu d'une clé (7) d'arrêt de ce dernier, de sorte que dans la position d'ouverture de ladite clé (7), les pistons (3,3') peuvent se déplacer de manière combinée dans le sens vertical, et restent bloqués dans la position de travail lorsque la clé est dans la position de fermeture.
