This invention relates to a cabinet with shelves that can be pulled out of a containment space and related pull-out mechanism with improved guide.
When constructing furniture and in particular corner cabinets, which may have a modular structure, a known method for solving the problem of poor access to the inner compartment of the furniture through its door is to make the shelves such that they can be pulled out for use and then put back into the compartment with a reverse movement.
In fact, that allows the user to access and use the shelf in total comfort, without encountering any obstacles, and then put the shelf, along with the objects supported, back in the containment space inside the piece of furniture when he or she has finished handling the objects.
The movements of pulling out and putting back in the shelf through the access opening of the piece of furniture affect both the shape of the outline of the shelf and the trajectory that the shelf has to follow in order to: come out of the containment space of the piece of furniture; reach the outside of the piece of furniture; and go back into it during the reverse movement. In terms of shape, semi-circular shelves have proved able to provide a satisfactory compromise between usable surface and transit without obstacles through the access opening of the piece of furniture.
One prior art solution proposed by the same Applicant and described in document IT 102017000069780 presents a solution provided with a track having an essentially sinusoidal, two-lobe shape, basically defined by two consecutive arcs which are substantially semi-circular in opposite directions, which are closed at the opposite ends of the track. The pull-out shelf is moved by a control mechanism (for shelf movement) which essentially comprises a slider which is moved forward and backward along the track—with a suitable law of motion implemented within the geometric shape of the track—as well as between the closed ends of the track which prevent the slider from being able to release itself from the track.
That solution, although achieving significant advantages in particular with reference to simplification of the moving mechanism for the pull-out shelves, is susceptible to further improvement.
Within the scope of that technical purpose a first aim of the invention relates to the search for a moving mechanism which allows a very regular and repeatable sliding of the sliding parts even after a very prolonged period of use.
A second aim is the search for a high level of structural rigidity of the components which guarantees that the movable component parts will not accidentally be released even following any accentuated deformability induced by a high overloading of the object holding shelf.
The advantages of the invention are more apparent in the detailed description which follows, with reference to the accompanying drawings which illustrate an example, non-limiting embodiment of the invention, in which:
With reference to
The arms 5, 6 in turn sustain a shelf 9, which is also rotatable about a vertical line V and in particular the second arm 6 is provided with two component segments 10, 11, converging at an interposed articulated joint 12. The coordination of the movement of the above-mentioned arms 5, 6 is designed to allow the shelf 9 to travel along a horizontal trajectory with variable orientation of its positioning, in such a way as to pass through the access opening 3 of the cabinet 1.
In particular (
In particular, as shown in
The double sliders 14 are coaxial and connected to each other in a single body as well as being interposed between two said tracks 16, which are on either side and opposite one another.
The two opposite plates 16 may be monolithically connected to each other by screws (not shown) engaged in seats which are shaped to match them and are labelled 24.
The invention fulfils the stated aims. In fact, the presence of a double plate 17 in which double sliders 14 engaged in a double track 16 operate allows, all conditions being equal, halving of the contact pressure between the movable parts, with a consequent increase in the working lifetime of the invention.
Moreover, the high level of rigidity of the control and guiding means 13 means that the movement is extremely regular and repeatable under any shelf 9 load condition, also guaranteeing that the sliders 14 and the related tracks 16 are not accidentally released from each other. The invention described above is susceptible of evident industrial application. It may also be modified and adapted in several ways without thereby departing from the scope of the following claims. Moreover, all details of the invention may be substituted by technically equivalent elements.
