Abstract: In order to improve the behaviour of a museum display case towards objects exhibited therein, the display case is subjected to a heat treatment in which the museum display case is maintained at a treatment temperature for a treatment time. The treatment temperature is between 35° and 50° and the treatment time is at least 30 hours. In this way, the emission of harmful volatile substances, including VOCs (volatile organic compounds), is drastically reduced and consequently the objects displayed in the display case are not at risk of damages due to the presence of these volatile substances in the display case.

Abstract: A museum display case with climate control comprises a case bottom, a display space above the case bottom, a shelf inside the display space, and a housing for hygroscopic material facing into the display space below the shelf. The housing includes a housing window open in the case bottom, a housing frame fixed to the case bottom below the housing window, and a tray mounted in the housing frame. The tray is horizontally and vertically movable between a working position where the tray is raised vertically towards the display space at the window and a service position where the tray is at least partly pulled horizontally out of the housing frame.

Abstract: A method for treating museum display cases includes subjecting a display case to alternating heating and resting steps. The heat treatment process substantially reduces the emission of volatile substances, including volatile organic compounds (VOCs), from the materials comprising the display case. The reduction in volatile emissions prevents damage to museum objects subsequently exhibited within the treated display case.

Abstract: The museum showcase includes a supporting frame, at least one glass wall with an inner face and an outer face, and a fixing frame glued to the inner face of the glass wall by an adhesive and mounted on the supporting frame of the showcase. The showcase also includes for each glass wall a safety profile with a fixing portion and a retaining portion. The fixing portion is fixed to the fixing frame and to the supporting frame; the fixing portion rests at least partially on the inner face of the glass wall near its lower perimeter edge. The retaining portion is hooked to the perimeter edge of the glass wall to retain the glass wall against the fixing portion of the safety profile. The weight of the glass wall is therefore also supported by the safety profile, which reduces the shear stress to which the adhesive is subjected.

Abstract: A museum display case with a fixed case formed by fixed glass walls surmounted by an upper openable glass door. The openable glass door is slidingly openable with respect to the fixed case. The fixed glass walls and the openable glass door have, with respect to the display case, respective inner faces and outer faces connected by peripheral edges. The museum display case has two linear sliding guides between the openable glass door and the fixed case. The linear sliding guides are applied, on one side, on the inner face of the openable glass door near opposite peripheral edges of the openable glass door and, on the other side, on the peripheral edge of two opposite fixed glass walls. The linear sliding guides have dimensions corresponding to the thickness of the fixed glass wall to which they are applied.

Abstract: A service implement for a museum display case has a panel having shape and dimensions corresponding to those of a door of a compartment hosting hygroscopic material for the control of the relative humidity inside the museum display case. The panel has at least a through passage suitable for connection to an external source of air or for housing a detecting probe. With this service implement, the space provided for the compartment with hygroscopic material becomes an easy access into the display case. Thus, before the display case is used to accommodate delicate objects, it can be subject to treatment, monitoring or measuring relevant parameters inside the display case.

Abstract: A museum showcase includes a base, with a laterally accessible technical compartment and an upper platform, and an exhibition space above the platform, delimited by vertically extended glass walls. The glass walls include at least one multi-layered special glass wall, formed of an inner glass pane and an outer glass pane. The inner glass pane extends downwards to cover the base and includes an opening at the technical compartment. The outer glass pane extends downwards only to a height such that the opening in the inner glass pane remains free. The special glass wall includes an openable door shaped and sized to form an extension of the outer glass pane downwards to cover the base. In this way, the opening of the technical compartment is accessible by opening the door, without having to open access to the exhibition space. The inner glass pane ensures that the exhibition space remains closed.

Abstract: A museum display case includes a display space, a filtration system and a climate control system to treat air in the display space. The display case also includes a first air circulation circuit and a second air circulation circuit, which are separate from each other and both originating and terminating in the display space. The filtration system is included in the first air circulation circuit and the climate control system is included in the second air circulation circuit. By providing two independent and separate circulation circuits it is possible to operate such circuits at different intervals, each according to its respective needs, thus avoiding, for example, unnecessary activation of filtration due to the need to intervene on climate control or vice versa.

Abstract: A method for construction of a museum display case is presented. The museum display case has a platform and a case above the platform, the case having at least one opening door. The method includes: providing glass panes, applying first metal beams to the glass panes beforehand by gluing, forming wall units, providing second metal beams at the opening door, forming the case by assembling the wall units together by means of the first and second metal beams, so that the first and second metal beams form a load-bearing structure only when the wall units have been assembled, and fixing the load-bearing structure of the case to the platform. With this method, the load-bearing structure of the display case is not formed by a frame to which the fixed and opening walls are then applied, but by the first and second metal beams, the former being already pre-glued to the glass panes of the fixed walls of the display case. This method makes the assembly of the display case easier and faster.

Abstract: A museum showcase includes a guide system for a sliding door, including upper and lower guide mechanisms. The upper guide mechanism includes primary and secondary rails. The upper guide mechanism also includes a first slide unit and a second slide unit. The first slide unit has a rolling member on an upper horizontal track of the secondary rail, and a sliding block engaged on a vertical track of the secondary rail. The second slide unit has a rolling member on a lower horizontal track of the primary rail, and a sliding block engaged on a vertical track of the primary rail. Thereby, the upper guide mechanism is extremely strong. The weight of the door, entirely supported by the secondary rail, is discharged on the first rail by the two slide units to transmit both vertical and horizontal loads.
