Abstract

In an information cassette for receiving exchangeable information carriers including a carrier housing, the carrier housing has bent over top and bottom end walls and a T-shaped center web so as to form two information carrier sections covered by hinge lids on which the information carriers can be mounted and which have bottom walls with springs on which the hinge lids are seated in the carrier housing and which resiliently bias the hinge lids upwardly such that the top ends of the hinge lids are engaged behind the front edges of the bent-over carrier housing top end wall or the T-shaped center web, respectively.

Description

The invention relates to a display cassette for interchangeable Information carrier with a carrier housing in the at least one can be opened, at least partially, by a pivoting movement transparent hinged lid with at least one integrated compartment is arranged to accommodate an information carrier.

Such a display cassette is known from EP 0 383 042. The display cassette there essentially consists of a body, a hinged lid and a locking cassette. The hinged lid, which can be folded over the base body, is articulated stored on the body. The pivot axis of the hinged lid lies in the lower area of the body. In the basic body there are several compartments to hold partial information carriers arranged. Above these compartments is in the hinged lid a compartment for another partial information carrier arranged. The subject, including the information carrier it contains lies above and in front of the partial information carriers of Compartments of the basic body. Over the top of the closed Display cassette will be after loading or exchanging the partial information carrier the locking cassette about the combination slipped out of base body and hinged lid. The locking cassette locks the display cassette.

Such a cassette has several disadvantages. For one, it is Handling the display cassette cumbersome and time-consuming. So must always have at least to exchange partial information carriers two parts are moved. The locking cassette must be removed and the hinged lid can be folded forward. When folding forward can open the hinged cover fully, which causes the information carrier can fall out immediately. On the other hand, do not lie all information carriers on one level behind the lens, what u.a. readability due to unfavorable shadows or cause the front information carrier to slip.

Furthermore, there is the large attack surface of the locking cassette there is always the risk of being in contact with people or goods this is pushed upwards and the Display cassette opens.

The publication DE 85 19 139 U1 describes a price tag with two hinged lids closing towards the middle. The one in the price tag interchangeably inserted fanfolds are loose in the base in subjects. The upper hinged lid is used to close the Price tag swung down while the lower hinged lid is pivoted upwards. The hinged lids are on the bottom part permanently attached using film hinges. In the top hinged lid are two inner guide rails arranged, the record a card for the product name.

Furthermore, a display board is known from DE 72 22 056 U1, in the laterally insertable signs on separate cassettes are arranged. The signs sit in guide rails on the External walls of the individual cassettes. They are assembled by Side rails protected from falling out from the side. The cassettes themselves are used to replace the signs in one Lift and swivel movement removed and reinserted.

This display board has a complicated structure and requires several operations for changing the plates.

The invention is therefore based on the problem of a display cassette to create that with simple and uncomplicated handling a quick and safe change of partial information carriers allowed. At the same time, the display cassette should be robust his. In addition, by design, an unintended Prevent opening by external influences. Furthermore should be those known from the prior art Disadvantages are largely avoided.

The invention is solved with the features of the main claim. The individual hinged lid, which can be removed from the carrier housing and can be closed by means of a swiveling and lifting movement, has a viewing window which, with the exception of the upper front edge with three edges, adjoins side walls at least in some areas. When the display cassette is closed, the hinged lid is at least partially encompassed in the region of its two viewing window edges running parallel to its pivot axis, with the aid of a spring mechanism arranged between it and the area of the carrier housing - in the vicinity of which the respective bottom of a hinged lid is located - at least partially with it that supports the lens edge not adjacent to the spring mechanism or another front section against the carrier housing. The spring travel of the spring mechanism is greater than the closing stroke of the hinged lid in the support direction.
This construction enables an easy-to-use, robust display cassette. When the display cassette is closed, the hinged covers sit completely in the protective carrier housing. The spring mechanism and the guide parts in which the hinged covers are used are hidden in the carrier housing. In this way, the display cassette can withstand the usual mechanical shocks in all directions without damage. Even a falling display cassette does not open when it hits the floor.
Since the hinged lid side walls, and in the case of lids with several compartments, the dividers are also supported on the carrier housing, these display cassettes are also tread-resistant, so that a fallen cassette is not broken by accidental treading.
The most sensitive part of the display cassette is the spring mechanism, which pushes the hinged cover through the corresponding grips of the carrier housing or fixes it there. The spring mechanism can be designed in various ways. For example, it can consist of an elastic, compressible rubber hose, a rubber cord, an elastic plastic tube, plastic leaf springs, several rubber balls, or comparable spring elements. The spring elements can either lie loosely in the carrier housing or be attached to or molded onto this or the corresponding hinged cover.

In one embodiment, the spring mechanism consists of at least two spiral springs arranged in the respective hinged cover are. You sit there on the pivot axis of the hinged cover parallel bottom.

Figure 1 shows a display cassette in which in a carrier housing (10) two hinged covers (20, 21) arranged one above the other are arranged with integrated compartments. In the right part of the Figure 1 shows the hinged lid (20, 21) opened. With the opening angle shown, the hinged lid can be (20, 21) by pulling it out in the opening direction Take out the carrier housing (10). The upper hinged cover (20) is for example, a single subject in which as an information carrier inserted a card (1) with an applied description of the goods is. The lower hinged cover (21) here contains six Subjects of the same size, which act as partial information carriers, individual leporello (2) included. The Leporellos (2) can for example on the one hand a position of a total or partial price and on the other other product and / or packaging-related brief information play.

In Figure 2, the carrier housing (10) with a still to be installed Front bar (19) shown. The carrier housing (10) has a flat rear wall (11) on which the side walls (12, 13) Connect at least approximately at right angles. Above and below the rear wall (11) goes into encompassing side walls (15, 16) about. These side walls (15, 16) have a semi-cylindrical outer contour. For example, they go out seamlessly without a transition the rear wall (11). Together with the side walls (15, 16) the carrier housing (10) forms a largely c-shaped cross section, such as also clearly visible in the section of FIG. 5 is.

Approximately in the middle of the front of the rear wall (11) two continuous, parallel webs (17) arranged one above the other. The front strip is in a gap (18) between the webs (17) (19) inserted over the web of their t-shaped cross section and glued there if necessary. The webs (17) communicate in combination the front bar (19) the carrier housing (10) in an upper and lower area. Each area forms a separate one Recording for a hinged lid (20, 21), at least in each case the lower zone of which is channel-shaped or channel-shaped. In Figure 5 is the channel-shaped design in the enlarged detail of the upper area recognizable.

Of course, the front bar (19) can also on the carrier housing (10) be molded.

Each side wall (12, 13) of the carrier housing (10) has on their free edges per hinged cover (20, 21) a circular segment Recess (14). The recess (14) is per hinged lid area each halfway up. The depth of the recess (14) corresponds approximately to half the depth or half The thickness of the display cassette.

In Figures 3, 4 and 6, the hinged cover are in several views shown. The front of the single hinged lid (20, 21) forms the so-called viewing window (23). she is here completely transparent. If necessary, for example opaque through coloring, coating, printing or the like his. The lens (23) is with the exception of each upper front edge equipped with side walls (31, 32). Each vertically arranged side wall (31, 32) contributes Handle part (33). The individual handle part (33) fits when mounted and closed display cassette in the corresponding Recess (14) in the carrier housing (10). Between the carrier housing (10) and the handle part (33) is an approximately 1 mm wide gap available, cf. Figure 1, left representation.

On each side wall (31, 32) is parallel to the viewing window (23) a crossbar (34) arranged to grasp the individual Part information carrier (1, 2) is used. With the hinged lid (20) fix the two crossbars (34) the card (1) from Figure 1 normal to the viewing window (23). When inserting the with the Card (1) equipped hinged cover (20) is through the crossbars (34) prevents the card (1) when closing the Hinged lid (20) between one of the side walls (31, 32) and the carrier housing (10) is jammed, which is the proper Closing difficult or prevented.

The hinged lid (21) has between the side walls (31, 32) five parallel dividers (36), so that six compartments for receiving of partial information carriers (2) arise. Every divider (36) each has a crossbar (37) on both sides each forming a wrap protrudes about 1 mm above the separating web (36). The fan-folds (2) are supported against the encirclements the lens (23).

Each hinged lid (20, 21,) has a bottom (41), each on the side walls (31, 32) and the viewing window (23). in the single floor (41) are here two flexible, leaf spring-like Integrated elements (42), cf. Figures 5 and 6. These spiral springs (42), which are close to the side walls (31, 32) are arranged, protrude at an angle in the unloaded state 25 ° downward and outward from the floor out. A spiral spring (42) has the shape of a length consisting of two legs (43) and (44) angle, one Leg (43), which is also shorter than the other, approximately runs parallel to the floor (41). Both legs (43, 44) enclose a 155 ° angle here in the unloaded state. The kink between the legs (43, 44) is arcuate educated. The spiral spring (42) has its entire length an almost constant rectangular cross-section. It is also possible to change the spring rate of the spiral springs (42) over at least part of their length to develop a variable cross-section. For example the cross-section tapers towards the free end.

The spiral spring (42) has opposite the floor (41) surrounding it a margin of several tenths of a millimeter. This can they also twist slightly when compressed without touching the floor (41) to graze or cant.

The spiral springs support each other when the display cassette is closed (42) of the upper hinged cover (20) on the upper web (17) off while the spiral springs (42) of the lower hinged cover (21) on the inner, here flat inner floor of the lower side wall Support (16).

Each hinged lid (20, 21) is at the top and bottom - so in the area of the horizontal lens edges (24, 25) Viewing window (23) designed step-like. In the area of there formed two stages (26, 27) is the wall thickness of the hinged cover (20, 21) smaller than in the viewing area. The steps (26, 27) have a depth that is approximately the material thickness of the areas of the horizontal covering the hinged cover (20, 21,) Side walls (15, 16) of the carrier housing (10) or the Correspond to the wall thickness of the crossbar of the front bar (19). Because of this design lies with the display cassette closed the viewing panels (23) of the hinged covers (20, 21) and the front of the carrier housing (10) approximately in one plane.

The height of the lower step (27) is greater than the height of the top lying level (26) and greater than the closing stroke of the individual Hinged lid (20, 21,). The total height of a hinged lid (20, 21,) is larger than the clear distance between the lower edge the upper side wall (15) and the upper edge of the front bar (19) or the clear distance between the lower edge of the Front bar (19) and the upper edge of the lower side wall (16).

Since each hinged lid (20, 21) with the display cassette closed with the exception of the handle parts (33) is laterally enclosed, can the hinged lid (20, 21) only via a combined swivel-push movement be closed and opened.

An empty and closed display cassette is used for loading Partial information carriers (1, 2) opened in that, for example the hinged lid (20) to be opened on its two handle parts (33) is pushed down. At the top hinged lid (20) the shift movement is finished when the lower one Step (27) is completely covered by the front bar (19). In this case, the lens (23) is almost flush the front bar (19). Furthermore, in this position both spiral springs (42) their maximum preload. simultaneously the front edge (24) of the hinged cover (20) is below the encompassing lower edge of the upper side wall (15). From this The hinged lid (20) is swiveled out of position until it comes out from under the upper side wall (15) is. Then it can be removed diagonally forwards and upwards.

If the hinged lid (20) is only opened on one side - for example on only one handle part (33) - remains the not shifted corner of the front edge ((24) behind the wrap the upper side wall (15). Consequently, this can be Do not open the hinged lid (20). That provides protection from improper or inadvertently opening the display cassette represents.

After filling a compartment, the hinged lid (20) with the Bending springs (42) ahead from above into the carrier housing (10) used. For this purpose, the hinged cover (20) is opened at an angle held against the carrier housing (10) as he from the representation of the opened display cassette in FIG is recognizable. As soon as both spiral springs (42) on the upper Web (17), cf. Figure 5, the hinged lid (20) pressed down until its front edge (24) is below the bottom edge the upper side wall (15) passes through. Then into that Carrier housing (10) swung in hinged cover (20) from the spiral springs (42) until the upper one Step (26) completely behind that around the hinged cover (20) Lower edge of the upper side wall (15) has disappeared.

If the side walls (31, 32) and the dividers (36) in the upper areas to the rear - i.e. from the viewing window or the front edge (25) away - beveled at least by the lifting height are, the hinged lid (20, 21) after inserting his Bottom (41) in the carrier housing (10) by simply pressing be closed. The bevelled upper edges of the side walls (31, 32) or the partitions (36) force during the closing swivel movement the necessary lifting movement.

The display cassettes have, for example, on the back (11) of the carrier housing (10) a fastening device for attachment on the documents provided for this. These documents, among others Price labeling rails or the leading edges of Shelf compartments can carry dovetail-shaped Surveys by two on a display cartridge facing each other arranged rails can be engaged.
