DESCRIPTION

[0001]. Field of the invention

[0002]. The present invention relates to a container cabinet provided with a roto-translatable door.

[0003]. In particular, the present invention relates to a container cabinet provided with a door movable from a closing position in which the door is arranged on a front part of the container cabinet to an opening position in which the door faces a side wall of the container cabinet.

[0004]. Background art

[0005]. In the context of container cabinets provided with doors roto-translating with respect to a containing structure, a particularly felt need lies in the creation of resistant, highly durable, compact, easy to make and aesthetically elegant door opening and closing mechanisms.

[0006]. A known solution, the Less piece of furniture, produced by the applicant itself, provides for the use of a mechanism with a cam path in which two pins, fixed to a plate for the connection to a door of the container cabinet, are guided. Such a solution allows the door to roto-translate from the closing position of a compartment of the box-like structure of the container cabinet to an opening position in which the door is arranged outside a side wall of the box-like structure of the container cabinet. Thereby, the door in the opening position does not obstruct the space in front of the opening of the compartment and therefore the peripheral space of the container cabinet may be used.

[0007]. However, on the one hand, such a mechanism may be particularly noisy due to the mechanical interaction of the pins with the walls of the cammed or cam path and, on the other hand, it may incur a misalignment between the upper mechanism and the lower mechanism.

[0008]. Document JP 2000160921 discloses a solution for opening a roto-translating door of an exhibitor, in which two connection levers are provided between a side wall of the container cabinet and the roto-translating door, in which the two levers are in a vertically offset position. Therefore, such a solution is particularly bulky and takes up space inside the compartment, consequently preventing the use thereof as a container.

[0009]. In this context, the need is therefore felt to create a container cabinet with a roto-translating door in which the door opening mechanism has a smooth and silent opening and closing movement.

[0010]. Furthermore, the need is felt to create a container cabinet with a roto-translating door in which the opening and closing mechanism is as unbulky as possible, while maintaining a high mechanical strength.

[0011]. Solution

[0012]. It is an object of the present invention to overcome the drawbacks of the prior art and to provide a solution to the need of providing a container cabinet as defined in the appended claims. [0013]. By virtue of a container cabinet according to claim 1, it is possible to meet the aforementioned needs, and in particular to obtain a container cabinet provided with a door opening and closing mechanism which is resistant and durable with respect to the prior art.

[0014]. Some advantageous embodiments are the subject of the dependent claims.

[0015]. Drawings

[0016]. Further features and advantages of the assembly according to the invention will become apparent from the description provided below of preferred embodiments thereof, given by way of indicative, non-limiting examples, with reference to the accompanying drawings, in which:
