Definitions
- the present invention concerns a levelling device to be used particularly for levelling furniture.
- the known levelling devices comprise a first element capable of being stably attached to the item of furniture to be positioned, and a second element intended to rest on the ground and capable of being associated with the first element and movable in translation with respect to the same in order to vary the height of the levelling device, and accordingly the height of the item of furniture to be levelled, with respect to the ground.

Abstract
Description
- The present invention concerns a levelling device to be used particularly for levelling furniture.
- The known levelling devices comprise a first element capable of being stably attached to the item of furniture to be positioned, and a second element intended to rest on the ground and capable of being associated with the first element and movable in translation with respect to the same in order to vary the height of the levelling device, and accordingly the height of the item of furniture to be levelled, with respect to the ground.
- These devices also comprise a screw intended to be received inside the second element and translationally fixed to the first element in such a way that rotation of the screw causes relative translational movement between the first and second elements so as to vary the height of the levelling device.
- The know levelling devices also comprise a pinion intended to be engaged with the head of the screw and capable of being rotated from outside the item of furniture by means of a tool. Rotating the pinion causes a corresponding rotation of the screw in the second element and therefore a relative translational movement between the first and second elements of the levelling device.
- The known devices are formed in such a way as to be housed in a seat formed directly inside the structure of the item of furniture, for example inside a shoulder, and are capable of being actuated from outside the item of furniture by means of suitable tools, such as a screwdriver or a hexagonal key.
- A device of the type described above is shown, for example, in
WO 2009/056935 . - A disadvantage of these devices is the fact that the production process includes a tapping phase, in which the threading of the second element is carried out after the element has been moulded.
- This phase entails a considerable loss of time and an increase in the costs associated with the production process for the known levelling devices. Another type of levelling device according to the known art is described in
EP 1832201 . - In this device, the second element comprises a first portion internally threaded to allow the coupling between the second element and the threaded screw, and a second supporting portion spaced along the longitudinal translational axis with respect to the first portion and provided with a pair of longitudinal lightening openings.
- This device allows a reduction in the quantity of material used, but the disadvantages pointed out with reference to the device of
WO 2009/056935 remain. In addition, the devices produced according to the instructions ofEP 1832201 are not very stable and do not allow a solid coupling to be obtained between the screw and the second element of the levelling device. - The problem addressed by the present invention is that of producing a levelling device for furniture that overcomes the limits mentioned above with reference to the cited known art.
- In the context of this problem, a first aim of the invention is to provide a levelling device for furniture that is reliable, simple to produce and low in cost.
- A further aim of the invention is to provide a levelling device for furniture whose production steps are simplified and of reduced duration, and which, at the same time, provides a stable coupling between the various parts of the device and therefore offering a precise and durable functioning.
