Abstract
This museum showcase comprises a bearing frame and fixed and/or openable walls supported by the bearing frame. The bearing frame comprises a platform that includes joints connected to horizontal beams. The fixed and/or openable walls of the showcase are supported only by the joints. The weight of the walls is supported by the joints, whereas the horizontal beams are not subjected to significant stresses. It is thus possible to design the showcase in a particularly simple and therefore quick manner, choosing the lengths of each beam according to the dimensions of the showcase and leaving the support of the weights to just the joints.
Description
CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims priority to Italian Application No. UA2016A002429 filed on Apr. 8, 2016, which is incorporated herein by reference in its entirety.


FIELD

The present invention concerns a museum showcase, i.e. a showcase intended for being arranged in a display room such as a museum, an exhibition or similar and intended for conserving and displaying items of cultural heritage, such as works of art, historical artefacts and similar, in a protected environment. Hereinafter, sometimes for the sake of brevity just the term showcase will be used, by this in any case still meaning a museum showcase.


BACKGROUND

Showcases of this type must satisfy various requirements, in relation to the conservation and integrity of the displayed objects. In particular, high security must normally be ensured against possible unauthorised attempts at opening or breaking in, as well as ensuring adequate insulation between the internal and external environment. Moreover, it is suitable for these showcases to have a structure such as to facilitate the production processes.


For this purpose, showcase manufacturers use metallic materials—typically aluminium and iron—to make support structures, such as a bearing frame and/or a platform of the showcase; the fixed and openable walls of the showcase, typically made of transparent material, are mounted on these structures. Normally, the transparent material used is glass.


In particular, showcases have been developed with a base having a case formed from the walls mounted on top; the base houses the technical components of the showcase and it is thus normally closed by non-transparent walls, to prevent such components being seen; on the other hand, the walls of the case are totally or largely transparent to allow the displayed objects to be viewed.


The frame is normally built with beams welded together and then painted. In this way, it is possible to obtain a frame having the necessary solidity to adequately support all of the transparent walls (the weight of which can by very high, in large sized showcases) as well as any other element or accessory of the showcase.


The Applicant has realised that structures of this type are relatively complex to make.


The present invention thus sets the problem of facilitating the construction of the showcase.


SUMMARY

Consequently, the present invention concerns a showcase as defined in claim 1. Preferred characteristics are indicated in the dependent claims.


In particular, the invention concerns a museum showcase comprising a bearing frame and fixed and/or openable walls supported by the bearing frame, characterised in that the bearing frame comprises a platform that includes joints connected to horizontal beams, in which the fixed and/or openable walls are supported only by the joints.


In this way, the weight of the walls is supported by the joints, whereas the horizontal beams are not subject to significant stresses. It is thus possible to design the showcase in a particularly simple and therefore quick manner, by selecting the lengths of each beam according to the dimensions of the showcase and leaving the support of the weights to just the joints. Moreover, it is possible to easily define standard sizes for the joints, so as to be able to use the same joints for showcases of even very different sizes, the dimensions of the showcase only requiring the use of horizontal beams of different lengths; this can lead to an oversizing of the joints with respect to the need of any single specific showcase, however the advantages of such standardization certainly outweigh the drawbacks of such possible oversizing. The different lengths of the horizontal beams necessary to make showcases of different sizes do not require particular sizing calculations, except perhaps the choice of the length: indeed, the main weights of the showcase (i.e. the weights of the walls) still remain discharged substantially on only the joints. At most, it may be advantageous to use horizontal beams by selecting a range thereof of differentiated cross sections, since the greater dimensions of a showcase can make it advisable to in any case adopt greater sections for the horizontal beams.


Moreover, this structure allows quick and easy mounting of the showcase, as well as equally quick and easy dismounting thereof.


Preferably, the joints comprise corner joints, each connected to two horizontal beams. The presence of the corner joints, each connected to two horizontal beams, ensures the possibility of easily mounting on the joints both the openable walls, by means of hinges or other opening systems, and the fixed walls.


Preferably, the joints also comprise intermediate joints, arranged in intermediate positions on the horizontal beams. Indeed, the presence of these intermediate joints facilitates the support for horizontal beams of substantial length and also provides a further connection point for possible hinges, in the case in which the showcase has more than one openable wall on the same side.


Preferably, the platform comprises struts connected to two of the joints. Two joints connected in this way by struts form an assembly having particular solidity.


Preferably, the bearing frame comprises a ceiling, which includes upper joints connected to upper horizontal beams. The frame equipped with such a ceiling is provided with even greater solidity, which is particularly desirable in showcases of substantial height.


More preferably, the upper joints comprise upper corner joints, each connected to two horizontal beams.


More preferably, the upper joints comprise upper intermediate joints, arranged in intermediate positions on the upper horizontal beams.


These characteristics make it possible to have a substantial correspondence between the platform and the ceiling.


In order to connect the ceiling to the platform, preferably the museum showcase comprises vertical beams connected to the joints of the platform and to the upper joints of the ceiling. The vertical beams make it possible to discharge onto the platform (in particular onto the joints of the platform) the weight of the ceiling and of all of the possible elements or accessories carried by the ceiling; in this way, the vertical beams are in any case stressed substantially only by compression.


Preferably, each corner joint of the platform is connected to a respective one of the vertical beams and this vertical beam is connected to a corresponding one of the corner joints of the ceiling. In this way, the bearing frame is formed from joints (which carry substantially the entire weight of the showcase) and beams, including horizontal beams that are not substantially stressed and vertical beams that are stressed only by compression.


Preferably, each joint comprises a lower shell, an upper shell and connecting tie rods between the lower shell and the upper shell. Indeed, this structure with the two shells and the connecting tie rods makes it possible to adjust the joint in height, thus adapting it to horizontal beams having different sized sections.


Preferably, the lower shell and the upper shell comprise respective housing seats of the horizontal beams, in which each horizontal beam housed in said housing seats is clamped between said lower and upper shells by means of the tie rods. In this way, the height adjustment of the joint with respect to horizontal beams of different sizes is safe and easy.


Preferably, each joint comprises a threaded hole in one from the upper shell and the lower shell and a through hole in the other from the upper shell and the lower shell, and the tie rods are inserted in the through holes and in screwing engagement in the threaded holes.


Preferably, each joint comprises coupling seats provided on faces pointing towards the outside of the showcase. The coupling seats make it possible to couple any element, so that the weight thereof discharges directly onto the joint.


Preferably, each coupling seat comprises an upper shaped channel formed on the upper shell and a lower shaped channel formed on the lower shell, in which the upper and lower shaped channels are aligned with each other. In this way, the weight of any element coupled with the joint can discharge onto both of the shells thereof.


Preferably, the showcase comprises a bar inserted into the upper and lower shaped channels of one same coupling seat, wherein in the bar at least one threaded hole is formed. Such a bar allows any element to be coupled quickly and easily with the joint.


Preferably, the showcase comprises one or more from supports for walls, hinges, clamps or sealing devices, supported by joints by means of the coupling seats.


In a preferred embodiment, the museum showcase comprises support feet, applied to the joints of the platform, beneath them.

FIG. 12 shows a showcase 110 according to another embodiment of the invention. The showcase 110 essentially has all of the characteristics of the showcase 10 just described; therefore, the characteristics of the showcase 110 common to the showcase 10 are not described here in detail and in FIG. 12 they are simply indicated with the same reference numerals as the showcase 10.


In particular, the showcase 110 is provided with a platform 13, exactly like the showcase 10.


Differently from the showcase 10, the showcase 110 is provided with a ceiling 118, structured in an analogous manner to the platform 13. The ceiling 118 thus includes upper corner joints 119 and upper intermediate joints 120 connected to upper horizontal beams 121. The upper corner joints 119 are each connected to two upper horizontal beams 121 and the upper intermediate joints 120 are arranged in intermediate positions on the upper horizontal beams 121. The showcase 110 can also comprise vertical beams (not shown in FIG. 12), connected to the corner and intermediate joints 14 and 15 of the platform 13, and to the upper corner and intermediate joints 119 and 120 of the ceiling 118.


Similarly to what is outlined for the platform 13, each upper corner joint 119 comprises a lower shell 129, an upper shell 130 and connecting tie rods 131 between the lower shell 126 and the upper shell 127. Similarly, each upper intermediate joint 120 comprises a lower shell 132, an upper shell 133 and connecting tie rods 134 between the lower shell 132 and the upper shell 133.


Similarly to what is outlined for the platform 13, each upper corner joint 119 comprises a housing seat 136a, formed in the lower shell 129, and a housing seat 136b, formed in the upper shell 130. The upper horizontal beams 121 are housed in the seats 136a and 136b and are clamped between the lower and upper shells 129 and 130 by means of the tie rods 131. Each upper intermediate joint 120 comprises a housing seat 137a, formed in the lower shell 132, and a housing seat 137b, formed in the upper shell 133. The upper horizontal beams 121 are housed in the seats 137a and 137b and are clamped between the lower and upper shells 132 and 133 by means of the tie rods 134.


Similarly to what is outlined for the platform 13, in the upper corner joint 119, there are threaded holes in one from the upper shell 130 and the lower shell 129 and through holes in the other from the upper shell 130 and the lower shell 129; these holes (totally analogous to the holes 39 and 40 of the corner joints 14) are not highlighted in FIG. 12. The tie rods 131 are inserted in the through holes and screwed into the threaded holes. In the intermediate upper joint 120 there are threaded holes in one from the upper shell 133 and the lower shell 132 and through holes in the other from the upper shell 133 and the lower shell 132; these holes (totally analogous to the holes 41 and 42 of the intermediate joints 15) are not highlighted in FIG. 12.

The showcase 110 can comprise vertical beams connected to the joints 14, 15 of the platform 13 and to the upper joints 119, 120 of the ceiling 118. Each corner joint 14 of the platform 13 is connected to a respective one of the vertical beams and this same vertical beam is connected to a corresponding one of the upper corner joints 119 of the ceiling 118; other vertical beams can be connected to the intermediate joints 15 of the platform 13 and to the intermediate joints 120 of the ceiling 118.


As stated, the present invention makes it possible to design and make museum showcases in a particularly quick and simple manner. This is true for showcases of any shape and size, not only for parallelepiped shaped showcases like the showcase 10. In the case of different shapes, like in the case of the showcases 210 of FIG. 13 and 310 of FIG. 14, it is nevertheless possible to make frames with a shape that approximates the shape of the showcase, using for the support of the walls, depending on the shape thereof, supports of a specific shape or extensions in shaped sheet metal that join the frame (or the frames) to the curvilinear walls of the showcase. It is also possible to combine the frames with each other, so as to make compositions of adjacent showcases. The advantages of the invention remain clearly unchanged.
