Abstract
Description
- The field to which the invention is directed is the furniture. Although the invention has been specifically designed to solve the problem of lack of stability of the tables provided with several legs when in contact with floor surfaces not leveled or irregular, the same is liable to be used in any item of furniture provided with several support legs who may need stability against irregular supporting surfaces by leveling each leg independently of the others in order to get a perfect level of the holding furniture, that is why we indicate that the sector concerned is furniture in general.
- So far, in the market, there are different ways to adjust in height the support legs of tables and other furniture in order to be able to correct its stability in presence of irregular support ground or surfaces and with it to level the surface, avoiding the annoying effect "wobble". Mainly, the existing mechanisms employ a system of threading or screwing, either of the own leg or an external element that through manual manipulation serves for adjusting the leg height depending on the unevenness of the supporting surface.
There are also some complex hydraulic systems that allow self-regulation of the legs.
Faced with this state of the technique, the invention which is intended as a simple innovation without manual manipulation that allows leveling the table on any surface by a system of self-regulation of the leg itself, independently, thanks to the internal mechanism which solves easily and without a difficult manipulation the issue of a wobbly table, in the pubs, at home, in the garden, in the classrooms, office meeting tables etc.
The mechanism which constitutes the invention and that we hereunder explain solves that the tables whose legs incorporate the mechanism, by itself, in usual slopes, don't destabilize giving the solution to the problem of "wobble". Once inserted into the legs of any material manufactured and with the forms that the manufacturer of tables and legs required or desired, oval, round, rectangular, square or any others, the problem of possible "wobble" disappears. - The invention consists on the introduction at the lower end of each table leg a piece (leveler) characterized by having three overlapping components: an outer casing (1) that fits into the own table leg (4) and inside which a piston (2) provided with a spring (5) located in its turn inside a moving part (3) which will penetrate into the casing (1) according to the needs of the support surface until the correct setting of the leg to the ground depending on the presence of irregularities in the same. All this as reflects graphically
Figure 1 herein.
These three elements: casing (1), piston (2) and mobile part, located in each leg of the table (4), auto-regulate independently the height of each one of the legs in order to guarantee the stability of the table and leveling the surface for proper use without any handling or use of screws or threads, solving the problem of "wobble" of the table or furniture without manual manipulation.
To achieve the union of the three elements a fitting system is used, the casing (1) is provided at its top with a stop with the groove (6) with the optimal routing for height adjustment autonomously (figures 2 and 3 ), and thereby achieve the level of the table. The pressure exerted by the leg on the ground is received by the piston (2) located inside the mobile part (3) and will cause the rise of the same inside the cavity of the casing until the point of stability needed in each case with the help of the spring tension (5).
By achieving the stability thanks to the pressure of the table against the ground independently on each leg, nothing impede that the leveller element in its bottom or friction area with the ground could be in contact with a wheel or other external support element, at the manufacturer election. For this, it is sufficient to couple the desired wheel or element at the lower end of the mobile part (3). - To complement the description being made and in order to aid to a better understanding of the characteristics of the invention, a set of drawings, wherein illustrative and not limitative, are attached as an integrated part of the description, it shows the following:
-
Figure 1 shows a display of the invention, which includes how in the inside of any leg of a table or other item of furniture (4) is inserted or fitted a casing (1) with a vertical displacement groove at its upper part (6), in which the mobile lower part will move (3) equipped with an anchor element (7) in the casing (1) and in which a piston (2) with a spring (5) is located. -
Figure 2 represents the leveller object of the invention spread within the leg which it is how it looks like when it has not touched yet the ground or support surface. As it can be seen the piston (2) and the spring (5) are fully extended and the anchor element (7) occupies the bottom of the scroll groove (6) of the upper part of the casing (1) - On the other hand,
Figure 3 shows the leveller, an object of the invention closed, this means in contact with the ground or support surface. When the leg (4) is in contact, the mobile part (3) rises to stay resting on the ground or support surface and the piston (2) and spring (5) are as tense as necessary in order to exert the adequate pressure for leveling the surface, while the anchor parts (7) occupy their position in the anchoring zone (6) - Finally,
Figure 4 gives detail of the lace of part of the leveler element with indication of the upper casing (1) in which it has been introduced the lower mobile part (3) with the groove of displacement (6) by which the anchor elements will move (7) offering the outside appearance of the leveler piece. - The invention that is intended, as we have advanced, consists of a piece, external to the leg, placed in its inside and its lower end that will be in contact with the ground or support surface to achieve stability and with it the level of the furniture.
- There are two requirements for this invention, the existence of furniture with several support legs with a hollow section and an external element to be introduced inside each one of the legs for the levelling of the furniture according to with the unevenness of the support surface. This element that we call leveller consists of a piece that fits inside of the leg by a casing (1) in whose inside top an anchor pattern (6) has been made. This anchor pattern has inside the inner piston (2) that will press subsequently the spring (5); the piston (2) and spring (5) are embedded in the mobile part (3) that contacts the support surface and moves according to the pressure exerted by the own table on the ground, inside the casing (1) by the anchoring area with groove of displacement (6) by the anchor pieces (7) designed in the mobile part, that run through the anchoring zone (6) of the casing (1) up to occupy the correct height.
- When the levelling element is at rest (not in contact with the ground) it has the appearance that represents
Figure 2 , with the spring (5) fully extended in the absence of any pressure of the ground on the bottom surface to press the piston (2). Set the table or furniture on the ground, the mobile bottom part (3) which is the one to contact the same, will move through the inside of the upper part with the allowable clearance in accordance with the design of the upper casing as result of the pressure made by the weight of the table on the piston (2), remaining in the position depicted infigure 3 in more or less open position in relation to the weight of the table and the support surface.
