## Title
Cover for storage space affording access to a selected part thereof

## Abstract

A cover affords access to a selected part of a storage space. The arrangement provides at least one opening which can be configured and positioned at any location on the cover. The opening provides access to a limited area of the storage space.

## Background
TECHNICAL FIELD
The invention is usefully applied in the field of applications for closing cupboards and/or shelves destined to contain objects of various natures and sizes. One very useful application of the invention is in the medical supplies field
BACKGROUND ART
Covers of known type, constituted by doors or hatches and the like, generally exhibit the characteristic of being structured with openings which normally afford indiscriminate access to a whole range of stored objects. This usually means that once the door is open a certain time is required for searching out and identifying the object or objects sought.
Apart from the fact that this can lead to errors, numerous other drawbacks are incurred, all due to the fact that many objects are revealed by a single opening of the cover, usually a door.
The main aim of the present invention is to obviate the limitations and drawbacks inherent in the prior art.
In particular the invention proposes to provide a selective opening, which enables a determined section of space to be revealed, both in terms of size and position of the space.
A further aim is to enable precise and rapid identification of the position of single objects or groups of objects.
An advantage of the invention is to make both the object storing and retrieving operations extremely simple and rapid.
These aims and advantages and others besides are all achieved by the present invention, as it is characterised in the claims that follow.



Further advantages of the present invention will better emerge from the detailed description that follows of a preferred but non-exclusive embodiment of the invention, illustrated purely by way of non-limiting example in the accompanying figures of the drawings, in which:
FIG. 1 is an exploded schematic perspective view of the invention;
FIG. 2 is an overall schematic perspective view.



DISCLOSURE OF THE INVENTION
With reference to the figures of the drawings, 1 denotes in its entirety a cover for closing off a defined area, in the example a vertical storage space 3 (but which could be horizontal) which comprises means for generating at least one opening 2 which exhibits the characteristic of being configurable and positionable in any way, so that a defined zone of limited access to the space 3 is afforded.
The means for generating the opening 2 comprise at least a first pair of surfaces which are guided to move in at least a first direction (in the example, a vertical direction) and which are positionable along the first direction in any position; the free edges 10 and 10′ of the first pair of surfaces are arranged at a predetermined distance one from the other so as to define a first gap of predetermined size. The free edges 10 and 10′ can be brought completely together to render the space between them null.
At least a second pair of surfaces are exhibited, guided to move in at least a second direction, not parallel to the first direction and positionable in any position along the second direction, at which the free edges 20 and 20′ of the second pair of surfaces are arranged at a predetermined distance one from the other so as to define a second gap of predetermined size (which can be null). The second gap is arranged transversally to the first gap and is at least partially superposed thereon.
The first pair of surfaces are constituted by two first screens 11, 12 which are commanded to translate along parallel guides 13 and 14.
Similarly the second pair of surfaces is constituted by two second screens 21, 22, which are commanded to translate along parallel guides 23 and 24, transversally arranged with respect to parallel guides 13 and 14.
The first screens 11 and 12 are respectively fixed to first guide devices 15 and 16, slidably coupled with the parallel guides 13 and 14.
The first guide devices 15 and 16 are commanded to translate along the parallel guides 13 and 14 by mechanical transmissions of known type which are powered by gear reducers 17 and 18.
The first screens 11, 12 are fixed at their free ends 10 and 10′ respectively to the first guide devices 15 and 16.
First roller devices 19 and 19′ are provided to gather up the first screens 11 and 12 starting from opposite ends to the respective free ends 10 and 10′.
Similarly, the second screens 21 and 22 are respectively fixed to second guide devices 25 and 26, coupled with the second guides 23 and 24.
The second guide devices 25 and 26 are commanded to translate along the guides 23 and 24 by mechanical transmissions powered by gear reducers 27 and 28.
The second screens 21 and 22 are fixed at their free ends 20 and 20′ respectively to the second guide devices 25 and 26.
Second roller devices 29 and 29′ are provided to gather up the second screens 21 and 22 starting from opposite ends to the respective free ends 20 and 20′.
The first screens 11, 12 and the second screens 21, 22 are moved independently from each other in the two directions along the respective guides, by action of the gear reducers 17, 18 and 27, 28, which are commanded by a control unit which enables the single free edges 10, 10′ and 20, 20′ to be positioned independently in the designated storage space 3.
Thus an opening 2 can be created in the cover 1 which is constituted by the superposing of the two gaps comprised between the free ends 10, 10′ and 20, 20′ and which can be configured—in the example the shape is a rectangle—according to predetermined dimensions and positioned with precision in a pre-selected area of the storage space 3.
In other words, a window can be opened in the space 3, which window will be of the desired size and in the desired position, so as to enable access only to a well-defined zone of the storage space 3.
The control unit is provided with a memory, in which the various, opening positioned assumed by the screens are stored; the opening positions can correspond to the objects stored in the storage space 3 behind those positions.
Thus any memorised position can be called up, making the operation of finding an object in the storage space 3 very simple and rapid.
Not only is the retrieval of the desired object made much easier, as well as making it very difficult to commit errors, but also access is given only to that part of the storage space 3 in which the sought object is stored. This guarantees protection of all remaining parts of the storage space 3, which remain closed off by the screens and therefore inviolable and inaccessible.
In some cases, in order to improve the inviolability of the screens (even where strong screens are used), it is possible to use proper slatted shutters.
