Description

introduction

The invention relates to an archive box. In particular, the invention relates to an archive box for receiving documents or other items at multiple levels.

State of the art and disadvantages

Well-known exhibition boxes, so-called showcases. Such showcases have at least one single level, on the support surface of which the items to be displayed are arranged. This level is then covered with a transparent surface such as a glass or Plexiglas plate to protect the items to be exhibited. The walls of such showcases usually consist at least partially of a transparent material such as glass in particular.

Also known are showcases with several levels, on each of which objects can be arranged. The floors forming the levels are also at least partially transparent in order to allow the observer to see objects which would otherwise be covered by overlying storage surfaces. However, a disadvantage of such a showcase is that the viewing through several levels only works satisfactorily if the objects are small or have a large lateral distance from one another, and / or if the planes have a large vertical distance from each other. In the case of large, especially flat objects such as pictures or books, or in the case of small lateral distances of the objects to each other or too low vertical distances of the planes to each other fails this concept, since the objects either cover each other, or the lateral or vertical Distance must be chosen so large that only a small number of (then sufficiently visible) objects can be issued.

Furthermore, archive boxes for receiving objects are known. In particular, such archive boxes are known, which accommodate objects on several levels, for example by the use of laterally extendable drawers to have the same footprint of the archive box a larger usable storage space for the archived items available.

In order to combine the advantage of the visibility of a display case with the small footprint of an archive box, a combination of an archive box with a display case is thus conceivable in order to be able to present a large number of objects on a small footprint.

The problem with this is that only the top shelf can be kept visible at any time by Providing a transparent lid. The objects that lie in the exhibition levels below are visible only if the corresponding storage areas can also be viewed. These must be pulled out of the archive box. Thus, in addition to the topmost - only one more, arranged underneath storage space completely visible. Others, even further below arranged shelves are covered by the uppermost pulled-out shelf. This is also the case when the shelves are made of transparent material, since then prevent the objects themselves the review. If the walls of such an archive box are made of transparent material in the manner of a showcase, the levels can be viewed even when the drawers are closed, but not from above, but only from the side. The problems described in the context of the above showcase then even come to light in an intensified form.

To ensure visibility, the drawers with the shelves can be pulled out laterally. However, withdrawal is often undesirable to protect the exhibits from environmental or unauthorized access.

Another problem is that the lateral extraction of the shelves in confined spaces such as on narrow aisles is difficult, namely, especially when several people are in the immediate vicinity of the archive box and thus by their bodies at least as complete as possible pulling out of Block shelves. The same applies to arranged in the immediate vicinity of the archive box items such as seating or room walls.

Object of the invention and solution

The object of the invention is to provide a viewable archive box for objects, which provides a plurality of exhibition levels with shelves on a limited footprint, even at low lateral distances of the objects to each other and at low vertical distances of the exhibition levels to each other at least parts of below a supreme Storage surface arranged further storage surfaces are visible from above, without these other storage surfaces must be pulled out laterally.

description

The problems described are solved by the independent claims. Preferred embodiments are contained in the dependent claims, the following description, as well as the figures and their description.

The invention discloses an archive box for receiving items to be exhibited. According to the invention, this comprises a plurality of exhibition levels, each with at least one segment providing a shelf. An exhibition level corresponds to a "floor" which is ready to receive objects. The present invention is characterized in that at least the top of the archive box is at least partially transparent, and that at least one of the segments is movable in the interior of the archive box in the horizontal direction.

As materials for the at least partially transparent top are in particular glass and transparent plastics in question. The thickness of this surface is preferably selected as a function of its size such that it does not suffer any damage, in particular does not break, even under load, for example by persons supporting it.

In the simplest case, a segment according to the invention can extend over the entire base area of an exhibition level, which essentially corresponds to the footprint of the archive box. However, a segment preferably has a smaller area, so that at least in one direction a distance arises between the edge of the segment and the edge of the archive box. In this way, there is the possibility that this segment is movable inside the archive box.

According to a preferred embodiment, an exhibition level comprises a plurality of segments, at least one of which is movable in the horizontal direction. However, it is also possible to move several or all segments of a respective exhibition level. It is clear that a certain segment can only ever be moved so far that it hits the inner wall of the archive box or another segment. In the case of a plurality of movable and adjacent segments, it is possible to push by moving a single segment of its directly or indirectly adjacent segments and thus to move.

According to a particularly preferred embodiment, it is provided that the lowermost exhibition level is immovable, and that each of the remaining exhibition levels comprises at least one movable segment. The lowermost exhibition level thus preferably forms the bottom of the archive box, while the remaining exhibition levels comprise a plurality of movable segments.

In principle, the archive box can have an arbitrarily shaped base area. However, it is preferred that it has a rectangular base and a horizontal longitudinal axis, and that the segments are movable parallel to this longitudinal axis. However, it is also conceivable that several horizontal longitudinal axis exist, along which the segments are movable. Finally, it is also conceivable that the segments are freely movable in the respective horizontal exhibition level.

Another embodiment provides that the archive box has a round base and a vertical axis of rotation, and that the segments are movable about this axis of rotation.

Furthermore, the archive box can basically comprise any number of exhibition levels. The archive box preferably comprises between two and six, and particularly preferably four, exhibition levels.

In order to ensure the independent mobility of the individual movable segments, a corresponding storage is provided. According to a preferred embodiment, plain bearings are used for this purpose. Particularly preferred is provided as a plain bearing for the movable segments or felt. Alternatively, however, for example, low-friction plastic pairings, magnetic bearings or ball bearings are possible.

According to the invention, it is provided that the archive box according to the invention comprises movable segments. For actuation, that is to say for the movement of the movable segments, basically all possibilities known from the prior art are considered. These include both direct-acting, mechanical means (levers, gears) as well as indirectly acting, for example electrical means (motors, electromagnets). The funds can be controlled controllable or, for example, random. It is preferred that the or the movable segments from outside the archive box are manually operated. Manually operable means that indirectly (for example, by sensor surfaces) or direct mechanical force of the user, a movement of the corresponding movable segment can be caused.

For this last-described case, ie the direct mechanical actuation, it is provided that the or the movable segments protrude from at least one slot arranged laterally of the archive box. By acting in the direction of movement, mechanical force can so the corresponding segment can be moved directly without having to intervene in the interior of the archive box. Preferably, the slot has a height which is only slightly greater than the thickness of the protruding part (handle) of the movable segment.

The handle can consist in the simplest case only by the projecting out of the archive box part of the respective segment. This part may additionally comprise grip aids such as depressions, holes, a corrugation or the like, or consist of or comprise an additionally attached element such as a metal handle.

According to the invention, the archive box can comprise further elements, both individually and in any combination, which are enumerated below.

Accordingly, the archive box can have at least one sealant against dust, light and / or intermeshing. Preferably, the sealant provides all of these functions equally. The sealing means is provided in particular in the region of the slot preferably described above, in order to close it wherever it is not pierced by the handle of a movable segment. Of course, the sealant must not significantly impede the mobility of a segment.

It is particularly preferred that the sealing means comprises a brush seal. Such a seal consists of a plurality of, for example, vertically arranged bristles, which touch each other, so that they form a substantially dense surface in their rest position. Since the bristles are flexible, they give way when the handle of a movable segment brushes them, and go back to their rest position after passing the handle.

It is further provided that the archive box according to the invention can comprise means for guiding and / or removal by pulling out the at least one movable segment. The guide means serves to determine the direction of movement of the segments. Without this means, the segments would be able to move indefinitely, which is often undesirable. The removal-removal means of the at least one movable segment ensures that the segment can not be removed unintentionally or by unauthorized persons from the archive box at least so far that the objects located on it can be removed. Preferably, these two means are provided by one and the same component.

It is therefore particularly preferred that the means for guiding and / or removal by pulling out the at least one movable segment comprises at least one blind spring. Such a blind spring, which is for example firmly connected to the archive box, cooperates with a corresponding recess, which is then provided in the movable segment. The movable segment can move along the direction predetermined by the dummy spring. Another direction of movement, in particular a movement which is perpendicular to the side wall, however, is not possible.

It is further provided that the archive box according to the invention can comprise at least one backup of the items to be exhibited against a relative movement to the respective segment. This means that the objects arranged on the respective segments must not slip or fall over during acceleration or deceleration of the segments. The objects can be arranged directly on the shelves of the segments, or on intermediate carriers (shelves). For fixing the objects comes, for example, a frictional connection means such as double-sided adhesive film, which does not harm the respective materials in question. The trays can also be held, for example, with such a film, and / or with screws, bolts, dowels or other positive connection elements on the respective segments. It is preferred that the connecting elements are provided in the segment and the cooperating openings in the tray.

Finally, it is preferably provided that the archive box according to the invention comprises means for hard striking a movable segment. When moving a segment, it may happen that it bounces unchecked at a high speed on an adjacent segment or against the inner wall of the archive box. There is a risk of damage to both the archive box and the issued items. To reduce this risk, one or more such means are located at each exhibition level, which includes movable segments. Particularly preferred are gas spring, alternatively or additionally, for example, steel or plastic springs may be provided.

Moreover, it is preferred that the archive box further comprises at least one illumination. This illumination is particularly preferably mounted in the upper edge region of the at least partially transparent upper side of the archive box, wherein an exit of the light in the direction of the transparent upper side through corresponding apertures is avoid. Fluorescent tubes are particularly suitable as illumination means, since they provide a uniform light with relatively low heat development. Further preferred illumination means are light-emitting diodes and fluorescent / luminescent surface radiators.

It can also be provided that information about the contents of the archive box can be arranged at least on parts of the at least partially transparent surface of the archive box. This information may be presented, for example, in printed, electronic and / or audible form. For this purpose, at least one separate deposition surface arranged on the at least partially transparent surface is preferably provided. This shelf can be fixed or movable. It can extend over the entire depth of the archive box, or just over part of it.

The archive box according to the invention can also be connected or equipped with a monitoring of its interior arranged items such as an alarm system. It may further include means for secure closure, such as any locks known in the art. These means can serve both against unauthorized removal of the at least partially transparent surface of the archive box; However, they can also secure an optionally provided door through which the segments can be inserted or pulled out in their exhibition levels. In the case of a rectangular base of the archive box such a door is preferably provided on one of the two side walls, which are arranged perpendicular to the direction of movement of the segments.

According to a preferred embodiment, it is provided that (in the case of a rectangular base area of the archive box) at least one longitudinal exhibition plane has a two-part division into two longitudinal halves, and that each of these longitudinal halves has its own segment arrangement. This means that both long sides of the archive box can be used by different users without the positions of the respective segments interacting with each other.

According to a further embodiment, which likewise has the longitudinal division described above, it is provided that the segments of both longitudinal halves are at least partially connected to one another. This means that the actuation of a segment on one longitudinal side of the archive box leads to a simultaneous actuation of the segment located on the other longitudinal side of the archive box. Such a coupling may be provided according to the invention for some or all movable segments of a respective exhibition level.

It can further be provided that the connection regions of adjacent segments have recesses which lead to a passage to the underlying exhibition level remaining free even in the case of directly adjoining segments.

The archive box according to the invention is preferably used for presenting coherent information, wherein this information can be grouped hierarchically, chronologically and / or thematically in the respective exhibition levels and / or segments. For example, it can be provided that, with regard to a topic, more in-depth information is also presented in an exhibition level of the archive box arranged further down. Similarly, chronologically older information below and chronologically newer information can be presented earlier. Accordingly, the archive box according to the invention is particularly suitable for use in exhibitions or at fairs.

• – Öffnen der mindestens teilweise transparenten Oberseite;
• – Positionieren des zu bestückenden Segments derart, dass es von der Oberseite her zugänglich ist;
• – Bestücken der Ablagefläche des Segments mit den Gegenständen oder mit einem diese Gegenstände haltenden Tablar;
• – ggf. Sichern der Gegenstände bzw. des Tablars auf der Ablagefläche des Segments;
• – Schließen der mindestens teilweise transparenten Oberseite.

The present invention also discloses a method for equipping an archive box according to the invention. At least the following steps are necessary:

• - Opening the at least partially transparent top;
• - Positioning of the segment to be loaded such that it is accessible from the top;
• - equipping the storage surface of the segment with the objects or with a shelf holding these objects;
• - if necessary, securing the objects or the tray on the storage surface of the segment;
• - Close the at least partially transparent top.

In other words, for equipping the archive box or for subsequent modification of parts of its contents, it is not necessary to remove all segments of the corresponding exhibition level from the archive box, but due to the displaceability of the individual segments they can each be positioned so that the modifying exhibition level and on this the desired segment area is accessible from above. For safe lifting of the at least transparent surface glass lifter or the like are preferably used. In the case of the presence of a corresponding safety device, this must be solved before carrying out the above-described steps, and then again to press. In the case of the presence of the trays described above, it may be sufficient to remove a whole tray from the archive box, to repackage, and then reset again as a whole to the respective segment.

After placement of the archive box according to the invention for the operation of the invention is prepared. This is characterized in that the movable segments are displaced by the action of the user so that the support surface of the desired segment is visible from above through the at least partially transparent top. In other words, the mobility of the individual segments, in conjunction with the at least partial transparency of the surface of the archive box, allows a user to expose the view to ever deeper levels of exposure by moving certain segments, without the need to remove the corresponding segments from the archive box would.

Due to the interaction with the movable segments, the user also experiences an increase in attention, thus thus a better and more intensive experience when recording the information transmitted by the archive box according to the invention.

At the same time, the objects in the archive box are protected against environmental influences and unauthorized access. Due to the mobility of the segments, a large amount of information can be presented on a small footprint effectively and fully accessible. This is a great advantage especially in confined spaces. Due to the possibility of using inexpensive materials such as wood, felt, and glass, the production cost of a storage box according to the invention can be kept low. Due to the easy interchangeability of individual shelves as well as the ability to exchange entire segments or even exhibition levels, the interior of a storage box according to the present invention can be repeatedly made new and flexible.

The invention thus makes it possible to provide a viewable archive box for objects, which provides a plurality of exhibition levels with shelves on a limited footprint, even at low lateral distances of the objects to each other and at low vertical distances of the exhibition levels to each other at least parts of the below a top shelf arranged further storage surfaces are visible from above, without these other storage surfaces must be pulled out laterally.
