Technical Field
The present invention relates to a cabinet having a shelf which can be pulled out of a receiving space and located outside the cabinet and which can be put back into the receiving space in turn. A pull-out mechanism is also part of the invention.
Background
In the design of furniture and in particular of corner cabinets, which may have a modular structure, a known way of solving the problem of difficult access to the internal compartment of the furniture through the door of the furniture is to make it possible for the shelf to be pulled out for use and then put back.
In fact, this way allows the user to access and use the shelf very comfortably, without encountering any obstacle, and to subsequently place the shelf, with the items it supports, back into the accommodation space within the piece of furniture after the user has finished disposing of the items.
The movement of pulling and replacing the shelf through the access opening of the piece of furniture affects the shape of the profile of the shelf and the shelf must follow a trajectory in order to achieve the following objectives: away from the accommodation space of the furniture; out of the furniture; and back into the furniture during the reverse movement.
Since the trajectory and the contour shape are related to each other, they are mutually influenced. In fact, the trajectory affects the shape of the shelf and the extent of the surface it can use in order to support the objects inside the containment cabinet.
In terms of shape, it has been found that a semicircular shelf provides a satisfactory compromise between usable surface and ease of passage, i.e. without creating obstacles when passing through the access opening of the furniture.
In fact, the substantially semicircular shape, although smaller than a square and/or rectangular similar fixed shelf, provides a satisfactory load surface. With regard to the ability of this shape to pass through the door, tests have shown that this can be achieved by moving on a generally sinusoidal trajectory that allows the semi-circular shelf to pass around the first of the two vertical edges (that define the door) and then around the other vertical edge.
A first embodiment of a mechanism suitable for allowing such movements of the shelves, known from document US2006/0012273, comprises a support column with a vertical axis of rotation, located inside the housing space of the piece of furniture and behind one of the door posts, and a hinge with a vertical axis, supported by one side of the piece of furniture behind the other door post. Proceeding from the upright and the hinge, cantilevered (cantilever-style) horizontally projects, there being two arms that can rotate independently and oscillate angularly about respective vertical axes of rotation. The two arms support the shelf in combination at two separate points of the shelf. By rotating the two arms in opposite directions about the post and the hinge, the semicircular shelf can be practically completely pulled out of the receiving space of the furniture and in turn be placed back into the receiving space by a reverse movement.
Another solution described and shown by document EP2415370 also comprises a column inside the containment compartment, which supports, cantilevered, an L-shaped bracket (blacket), which can rotate horizontally around the column, and supports a curved guide device on which a trolley (trolley) supporting the shelf is mounted. The L-shaped support rotates around the post, following which the trolley translates along the guide means, allowing the shelves to progressively follow a trajectory oriented such that they can come out through the door, outside the housing space of the furniture, along said trajectory and then be put back into the housing space by a reverse movement.
Disclosure of Invention
This solution solves the drawbacks of the prior art well. However, it still has some potentially improvable aspects that are particular technical goals of the invention.
Within the scope of this technical aim, a first object of the invention is therefore to find a shelf shape which, although limited in relation to the movements of removal and replacement of the receiving space, has a larger usable surface than the solutions of the aforementioned prior art, while the dimensions of the receiving spaces of the cabinet of preset dimensions, intended to receive the movable shelf, are equal.
A second object of the present invention is to devise a structure of the shelf movement control device which is simpler and less costly to manufacture and which is mechanically more reliable, thus guaranteeing a long product life.
These results are achieved, according to the present invention, by means of a cabinet equipped with a pull-out shelf and a pull-out mechanism, the technical characteristics of which are described in one or more of the appended claims.
