DESCRIPTION

Furniture leg leveler.

Technical sector

The sector of the technique to which the invention is directed is that of furniture. Although the invention has been specifically designed to solve the problem of the lack of stability of the tables provided with several legs when they come into contact with uneven or uneven floor surfaces, it can be applied to any furniture element provided with several support legs that may need stability against irregular support surfaces by leveling each of them independently of the rest to achieve a perfect level of the furniture they hold, so we indicate that the sector of the affected technique is the of furniture in general.

Background of the invention

So far in the market there are different means to regulate in height the support legs of tables and other furniture in order to correct its stability in the presence of floors or irregular support surfaces and thereby leveling its surface, avoiding the annoying effect of the "limping." Mainly, the existing mechanisms employ a screwing or screwing system, either of the leg itself or of an external element, which by means of manual manipulation serves to adjust the height of the leg according to the unevenness of the support surface.

There are also complicated hydraulic systems that allow self-regulation of the legs.

Faced with this state of the art, the invention that is intended involves a simple innovation that without the need for manual manipulation allows the table to be leveled on any type of surface by a self-regulating system of the leg itself, independently, thanks to the internal mechanism which solves the problem of a lame table easily and without complex manipulation. In cafeterias, at home, in the garden, in training classrooms, office meeting tables etc.

The mechanism that constitutes the invention and we explain below resolves that the table whose legs incorporate the mechanism, by itself, on usual slopes does not destabilize giving the solution to the limping problem. Once inserted in the legs of any material in which they are manufactured and with the shapes that the manufacturer of tables and legs requires or desires, oval, round, rectangular, square or any other, the problem of possible limping disappears.

Explanation of the invention.

The invention consists in the introduction at the lower end of each of the legs of the table of a piece (leveler) characterized by presenting three overlapping components: an outer casing (1) that fits into the table leg itself (4 ) and inside which there is a spring (2) provided with a spring (5) located in turn inside a moving part (3) that will penetrate inside the housing (1) according to the needs of the support surface up to get the correct fixation of the leg to the ground according to the presence of irregularities in it. All this as shown in figure 1 of this report.

These three elements: housing (1), spring (2) and moving part (3), located at the end of each table leg (4), self-regulate independently of each other the height of each of the legs in a way that the stability of the table is guaranteed and the surface of the table is leveled for proper use without the need for any manipulation or the use of screws or threads, solving the problem of lameness of the table or furniture without the need for any manual manipulation.

To achieve the union of the three elements, a fitting system is used, for which the housing (1) in its upper part is provided with a stop with groove (6) of optimal travel to regulate the height autonomously ( Figures 2 and 3), and thereby achieve the leveling of the table. The pressure that the leg exerts on the ground is received by the spring (2) located inside the moving part (3) and will cause it to rise inside the cavity of the housing until it is at the point of stability that is necessary in each case with the help of spring tension (5).

By achieving stability by the pressure of the weight of the table itself on the floor independently on each leg, nothing prevents the leveling element at its bottom or friction with the floor, is in contact with a wheel or other element external support, at the manufacturer's choice To do this, simply attach the desired wheel or element to the lower end of the moving part (3).

Brief description of the drawings

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description, where illustrative and non-limiting nature, the next:

Figure 1 shows a drop-down of the invention, which includes as inside any table leg or other furniture element (4) a casing (1) with a vertical sliding slot in its upper part (6) is inserted or fitted, through which the moving lower part (3) provided with an anchoring element (7) in the housing (4) and inside which a spring (2) with spring (5) is to be moved.

Figure 2 represents the leveler object of the invention extended inside the leg which is as it is when it has not yet touched the ground or support surface. It looks like the spring (2) and the spring (5) appear fully extended and the anchoring piece (7) occupies the lower part of the sliding groove (6) of the upper part of the housing (1).

For its part, Figure 3 represents the leveler object of the invention closed, that is, in contact with the floor or support surface. When the leg (4) is supported, the moving part (3) goes up to rest on the ground or support surface, leaving the spring (2) and the spring (5) as tense as necessary to exert adequate pressure and level the surface, while the anchor pieces (7) occupy their position in the anchor zone (6).

Finally, Figure 4 gives details of the fitting of parts in the leveling element with indication of the upper housing (1) in which the lower moving part (3) is inserted with the sliding groove (6) through which they will move the anchoring elements (7) offering the external appearance of the leveling piece.

Preferred Embodiment of the Invention

The invention that is intended as we have advanced consists of a piece external to the leg that is located inside and at the lower end of it which will be the one that comes into contact with the ground or support surface to achieve its stability and with it the leveling of the furniture.

There are two requirements of the invention, the existence of a furniture with several hollow section clamping legs and an external element to be introduced in each of the legs for the leveling of the furniture according to the irregularities of the support surface. This element that we call leveler consists of a piece that fits inside the leg by means of a housing (1) in whose upper internal part an anchor design (6) has been made that in turn locates the internal spring (2) that subsequently press a spring (5); the spring (2) and the spring (5) are embedded in the moving part (3) that comes into contact with the support surface and moves according to the pressure exerted by the table itself on the floor, inside the housing (1) through the anchorage area sliding groove (6) by means of the anchoring parts (7) designed in the moving part, which run through the anchoring area (6) of the housing (1) until the appropriate height is occupied .

20 When the leveling element is at rest (not in contact with the ground) it has the aspect shown in Figure 2, with the spring (5) fully extended as there is no ground pressure on the lower surface that presses the spring (2 ). Putting the table or furniture on the floor, the moving lower part (3) which is the one that comes into contact with it, will move through the interior of the upper part with the clearance allowed according to the design of the upper housing as a consequence of the pressure of the weight of the table itself on the spring (2), being in the position shown in figure 3 in a more or less open position in relation to the weight of the table and the support surface.
