Abstract
This showcase for the preservation and display of objects in a protected environment, comprises a bell, a base and pantograph mechanisms housed in lateral end regions of the base and formed by arms, pairs of arms and lower arms, the latter with a curvilinear configuration. The pantograph mechanisms are actuated by actuation systems housed at the bottom of the lateral end regions of the base. The showcase ensures an easier recovery of the space otherwise occupied by the actuation systems and at the same time an appropriate opening of the showcase.
Claims3
A museum showcase comprising:
- a base comprising a first actuation system and a second actuation system;
- a bell that can be lifted with respect to the base, the bell comprising transparent walls for showcasing objects within the bell;
- at least two pantograph mechanisms for lifting the bell, each of the at least two pantograph mechanisms having movable arms hinged together, and including:
- i) a pair of lower arms hinged to the base, comprising a first lower arm hinged to the base via a fixed pin, and a second lower arm hinged to the base via a movable pin along the base under control of a respective actuation system of the first and second actuation systems;
- and
- ii) a pair of movable arms hinged to the bell;
- wherein:
- for each of the at least two pantograph mechanisms, the first lower arm and the second lower arm have a curvilinear configuration, said first lower arm and second lower arm forming, in combination, a concavity facing downwards to allow spacing for placement of the respective actuation system between the fixed pin and the movable pin in both a fully retracted and fully extended state of the each of the at least two pantograph mechanisms.
