BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Further characteristics and advantages of the present invention will become apparent from the following description of a non-limiting embodiment with reference to the figures of the accompanying drawings, wherein:

[0029] FIG. 1 is a perspective view of a casing for housing and transporting stage production material according to the present invention in a first operating position;

[0030] FIG. 2 is a perspective view of the casing of FIG. 1 in a second operating position.

DETAILED DESCRIPTION OF THE INVENTION

[0031] FIG. 1 indicates with the reference number 1 a casing for housing and transporting stage production material (not shown for simplicity's sake in the attached figures) in an open configuration.

[0032] In the non-limiting example here described and shown, the casing 1 is designed for housing two stage projectors, as shown in more detail hereinafter.

[0033] The casing 1 comprises a hollow main body 2, shaped so as to define a seat 3 for housing the material, and a cover 4.

[0034] The cover 4 is mobile between a closed position (shown in FIG. 2), wherein the cover 4 closes the seat 3, and an open position (shown in FIG. 1), wherein the cover 4 is arranged in such a way that the seat 3 is accessible to allow positioning the material.

[0035] In the closed position, the cover 4 is coupled to the main body 2 by geometrical coupling. Advantageously, the geometrical coupling is such that it does not require the use of seals and ensures a good seal against water and dust.

[0036] In the non-limiting example here described and shown, the cover 4 is provided with two perimeter grooves 5a, which are engaged in the closing position by respective perimeter ribs 5b formed along the edge of the main body 2.

[0037] The main body 2 preferably has a parallelepiped shape and is at least partially made of a first expanded polymer, preferably expanded polypropylene (EPP).

[0038] The first expanded polymer preferably has a density comprised between about 50 g/l and 70 g/l. In the non-limiting example here described and shown, the density of the first expanded polymer is of 60 g/l.

[0039] Preferably, the main body 2 is made in one piece, for example by moulding.

[0040] Externally, the main body 2 is provided with a base surface 6 (not visible in the attached figures) and with a lateral surface 7.

[0041] Preferably, the main body 2 is provided with a plurality of wheels 8 coupled to the base surface 6. In the non-limiting example here described and shown, the wheels 8 are four.

[0042] Along at least two opposite faces of the lateral surface 7, the main body 2 is provided with at least two grooves 10 coupled to respective handles 11, preferably of the retractable type. In this way, when the handles 11 are not used, the lateral surface 7 has no protrusions that might prove dangerous or be a hindrance during the movement of the casing 1. Preferably, the handles 11 are made of metal material.

[0043] In the non-limiting example here described and shown, the handles are eight (only four of which are visible in the accompanying figures), two for each face of the lateral surface 7.

[0044] A variant not shown provides that also the grooves 10 are shaped so as to define a gripping point, in order to avoid the use of the handles.

[0045] Internally, the main body 2 comprises an inner bottom wall (not clearly visible) and an inner lateral wall 14 (partially visible), which define the seat 3.

[0046] The inner bottom wall 13 and the inner lateral wall 14 are shaped so as to define at least a protection shell 15 designed to minimize the movements of the material which must be housed in the housing 3 during transport.

[0047] Preferably, the protection shell 15 is made of a material different from the material constituting the main body 2 and is removable.

[0048] Preferably, the protection shell 15 is at least partially made of an expanded polymer having a density lower than the one of the expanded polymer constituting the main body.

[0049] For example, the expanded polymer constituting the protection shell 15 has a density comprised between 30 g/l and 40 g/l.

[0050] In the non-limiting example here described and shown, the expanded polymer constituting the protection shell 15 is expanded polypropylene (EPP).

[0051] Preferably, the removable protection shell 15 is made by moulding.

[0052] In the non-limiting example here described and shown, the bottom wall and the lateral wall 14 are shaped so as to define two protection shells 15, each of which is designed to minimize the movements of two respective stage projectors (not shown for simplicity's sake in the attached figures).

[0053] The cover 4 is at least partially made of an expanded polymer, preferably expanded polypropylene (EPP), identical to the one used for making the main body.

[0054] Preferably, also the cover 4 is made in one piece, for example by moulding.

[0055] With reference to FIG. 2, the cover 4 is externally provided with a top surface 17, which is preferably provided with a plurality of reinforcement plates 18 and is internally provided with an inner surface 19 provided with a coating 20 (FIG. 1).

[0056] The reinforcement plates 18 have the function of reinforcing the cover 4 when different casings 1 are stacked one over the other, e.g. during transportation or storage.

[0057] In fact, the reinforcement plates 18 are arranged at the wheels 8, so that the wheels 8 of the casing 1 lying on the cover 4 rest on the reinforcement plates 18.

[0058] Preferably, the reinforcement plates 18 are slightly concave so as to define a sort of housing for the wheels 8.

[0059] The coating 20 is preferably shaped so as to cooperate together with the protection shell 15 to minimize the movements of the material housed in the seat 3.

[0060] The casing 1 is further provided with at least a closing device 22 (FIG. 2), designed to lock the cover 4 in the closed position, and with a driving device (not visible in the attached figures), designed to guide the movement of the cover 4 with respect to the main body 2 from the closed position to the open position and vice versa. In particular, the driving device comprises one or more hinges (not shown for simplicity's sake) coupled to the main body and to the cover and designed to allow a rotation of the cover around the same axis. Preferably, the driving device is also designed to lock the cover 4 in the open position and to allow an easy access to the seat 3.

[0061] Finally, it is clear that the casing described herein can be subject to modifications and variations without departing from the scope of the appended claims.
