EP0301482A2 - Window storing case - Google Patents

Abstract

The window storing case has a peripheral reinforcement profile in the manner of a hollow chamber profile. The reinforcement profile forms an upper stacking edge and surrounds a window opening at the front side of the case, into which opening a collapsible window pane (10) can be inserted, the window pane (10) being swivellable about pivots (11), which are mounted in recesses (9), for collapsing. In the collapsed state, the window pane lies flush against the end wall (1) of the case and has a recess (12a) in the region of the pivots (11) of such a size that it can only be displaced laterally in a particular position, namely at an angle of precisely 90 DEG to the end wall (1), by which means the pivots (11) can be taken out of or inserted into their respective recesses (9). The window pane is thus captively connected to the case and thus forms a unit. Furthermore, the window storing case can be provided with a dust lid (17), a compartment divider (14) or a label holder (6, 7). <IMAGE>

Description

The invention relates to a face storage box with a circumferential stiffening profile, which forms an upper stacking edge and has a viewing opening into which a hinged viewing window can be inserted, the viewing window being pivotable about a pivot which is mounted in a recess for folding down. Such a storage box is known from DE-OS 29 15 812.

The known storage box has a hollow chamber profile on its end wall, which surrounds the viewing opening on three sides. The hollow chamber profile merges at the upper peripheral edge of the box into a stacking edge with a horizontal stacking edge and an upward-facing vertical boundary edge.

A face storage box with a hollow chamber profile drawn around the entire box, but without an upwardly facing boundary edge, is known from DE-OS 30 14 387.

A viewing window can be inserted into the viewing opening of the box of the first-mentioned DE-OS 29 15 812. For this purpose, the edges of the viewing opening are provided with retaining grooves and webs. At its lower end, the known lens has an angled forward leg, on which pivot pins projecting sideways are formed. The spin reach behind bars that protrude into the viewing opening. The visor can be released from the holding grooves by lifting and then folded down around the pivot pin to the front. When folded down, the visor hangs more or less freely in front of the box front wall.

This arrangement has the disadvantage that it cannot be handled safely, especially not with mechanical devices. This means that even with manual handling of the box, the lens can easily accidentally move from its closed position into the open position. When the box is transported through mechanical devices, the lens can be unintentionally folded down due to the inevitable vibrations. This has some undesirable consequences: First, in addition to parts of the contents of the box, the viewing window itself can also be lost. Appropriate securing of the viewing window is possible by means of plugs which can be inserted into openings in the known box, but experience has shown that such additional securing elements tend not to be present if required. When the box is transported, for example on an inclined roller conveyor, the boxes being able to collide with considerable force, the viewing panes are easily destroyed, resulting in sharp-edged splinters which represent a considerable danger. Above all, however, a folded down viewing window prevents safe manual or mechanical gripping and lifting of the box, since it protrudes from the front of the known box.

In addition, the known face storage box is difficult to provide with compartments and additional elements because of these safety deficiencies, since these represent further uncertainty factors when handling the faceplate.

The object of the invention is to design the open fronted storage box so that, in particular when using compartments, simple handling, secured against loss and destruction, is also possible with mechanical devices.

This object is achieved in that the visor lies flush against the end wall of the box in the folded state, and that in the region of the pivot, the visor has a recess which, when the visor is in a position relative to the end wall of the box, of exactly 90 degrees, and only in this position, the insertion and removal of the pivot pin in or out of the recess by lateral displacement from the central position to the viewing opening.

The open front storage box according to the invention has the advantage that the viewing window forms a unit with the box and does not hinder manual or mechanical gripping of the box neither in the folded-up state nor in the folded-down state, since in any case it lies flush against the box and cannot be lost connected is. Handling is therefore independent of whether the lens is folded down or not. When the window is folded down, it can no longer break because it is supported flatly on the front of the box.

The lens preferably has an extension which, when folded down, engages under the front edge on the front wall of the box and forms a recessed grip. This supports the safe gripping and lifting of the box even when the viewing window is folded down.

With an additional equipment of the storage box with a dust cover contributes to safe handling, in particular by mechanical gripping devices, an embodiment in which the dust cover has two upwardly bent tabs on its back, which can be snapped into openings in the rear stacking edge of the box, so that the dust cover just as the lens can be placed captively, the upwardly bent tabs have a hinge effect, so that the dust cover is held on the box even when open.

A compartment divider can also be used in the open front storage box according to the invention, which can be inserted between strips in the box, the compartment divider advantageously having wide flanges at least on its edges abutting the walls of the open front storage box. This does not affect the good handling of the box, since the compartment divider with its wide edges is supported on the walls of the box and cannot slip. To define the compartment divider, only slightly bulky strips on the inside of the box are required, which do not interfere and which cannot clog with small parts or dirt.

The training with a label holder with grooves on the end wall, the grooves advantageously having a nose for holding the labels, ultimately contributes to the fact that labels can also be captively attached to the box, so that faults due to missing label labels or half-jumped out of their holders be avoided.

The storage bin according to the invention thus has a along the upper edge around the entire box and in particular around the hollow chamber profile pulled around the viewing opening. Captive lenses, labels and dust covers as well as non-slipping compartment dividers contribute to safe, in particular mechanical handling. The lens forms a unit with the box in such a way that the box can also be lifted when the lens is folded down.

Fig. 1 shows the storage box in an overall view. The box made of plastic has at its upper edge a circumferential hollow chamber profile, the outer walls of which are drawn relatively far downward in the area of the end wall 1 and around a viewing opening. Sufficient free space remains, however, up to the lower edge of the box, so that for handling the box, one can reach into the hollow chambers of the end wall which are open from below and are designed as a recessed grip. The downward-drawn hollow chamber profile continues around the front corners of the box and merges into narrower sections on the longitudinal sides 2 of the box.

On the long sides and also on the back of the box, the hollow chamber profile adjoins the side walls 2 or the rear wall of the box at right angles, horizontal sections 4 (FIG. 2) and, in turn, adjoining them, extending upwards and downwards Flanges 3, which run parallel to the corresponding side wall or rear wall. The part of the flange 3 which extends upwards forms a stacking edge together with the section 4 and the part which extends downwards forms the actual hollow chamber profile. This downwardly extending part of the flange 3 is connected to the wall 2 by webs 5 (FIGS. 2, 3) running perpendicular to the wall 2. The free lower edges of the webs 5 are curved upwards or concavely in order to make it easier to pick up the box on the side walls with mechanical gripping devices acting on the webs.

The lower edge of the box can additionally be provided with a stacking edge which interacts with the upper stacking edge when the boxes are placed on top of one another and which reinforces the lower edge.

Below the viewing opening, a label field is arranged in the end wall 1 of the box, which has a groove 6 (FIGS. 1, 4) running around on three sides, into which a label card or the like can be inserted from above, from the side of the viewing opening . In order to hold the label captively even when the box is tilted, the lower groove has an inwardly directed nose 7. The label is held particularly securely by the nose 7 when the label is placed in a transparent envelope which is folded once so that the fold can be pushed under the nose 7.

On the walls, e.g. On the side walls 2 of the box, markings 8 (FIG. 1) can additionally be made, which always facilitate the arrangement of machine-readable coding fields in the same place on the box, so that it is ensured that e.g. Optical identifiers can also be read automatically and a rotation of the box (turned upside down) can also be automatically recognized. These markings 8 can consist of elevations, depressions or the like formed on the walls.

Furthermore, some of the cavities of the hollow chamber profile can also be designed such that active coding elements can be inserted therein and fastened, for example, by snapping in, which interact with an automatic storage system for the automatic detection of the boxes.

Recesses 9 are arranged in the lateral boundary of the viewing opening of the box and accommodate corresponding locking and pivot pins 11 of a viewing window 10 (FIG. 5). The recesses 9 and the pin 11 cooperate so that the lens can only be mounted on the box in such a position that does not normally occur during operation, so that the lens is captively connected to the box. For this purpose, the lens 10 is provided with an angled leg 12 on which the lower pivot 11 are arranged. In the area of these pivots, the lens or the leg 12 has a shoulder or a recess 12a which, when the lens is in a position of exactly 90 ° to the front of the box, and only in this position, the insertion and removal of the lower pivot 11 in the lower recesses 9 of the viewing opening allowed. The view can be seen in all other positions do not move the washer laterally from a position in the center of the viewing opening, in which both of the lower pivot pins 11 are seated in the corresponding recesses 9. For this purpose, the recess 12a has the shape of an incision with 90 ° side walls, in which a web-shaped section of the end wall 1 can engage in the region of one of the recesses 9 in the case of a lateral movement only in the 90 ° position mentioned. At any other angle than 90 °, the incision and the wall section are tilted against each other and cannot interlock, that is, the viewing window is fixed laterally.

The visor 10 can be folded down in the assembled state by lifting and rotating about the pivot pin 11, with the angled leg 12 on the visor on which the pivot pins are arranged ensures that they are flush with the front of the folded-down state Front wall 1 of the box rests and forms a unit with it.

The lens 10 has an extension 13 which, when the lens is folded down, engages under the lower edge of the front of the front wall 1. The approach 13 is hollow so that it forms a recessed grip when the lens is folded down. When lifting the box on this recessed grip of the lens, this is secured by the interaction of the approach 13 and the lower edge of the front of the end wall 1, so that the box can be lifted manually and mechanically on the lens recessed grip. The lens does not interfere with the handling of the box even when it is folded down.

For dividing the box in the longitudinal or transverse direction (usually a division in the longitudinal direction is provided) compartment dividers 14 (FIG. 6) can be used. These compartment dividers 14 are provided on the edges or narrow sides with which they rest on the walls of the box, and possibly also on the narrow side lying against the bottom of the box with relatively wide flanges 15 which are supported on the box walls. The flanges 15 form an angle of slightly more than 90 ° on both sides with the plane of the compartment divider, so that a flat "V" is formed. In the event of a bending load, the flanges 15 are supported on the side opposite the bending load against the box walls. The compartment dividers 14 are fixed in the box 15 by means of low strips 16 on the inside of the walls of the box.

The top of the box can be covered with a dust cover 17 (FIG. 7). The dust cover 17 lies on the upper stack edge of the box and has on the back two tabs 19 which are bent upwards at an angle of approximately 30 ° and which engage in corresponding openings in the rear stack edge of the box. The dust cover can thus only be inserted and removed in an inclined position of approximately this 30 °, so that the dust cover is also captively attached to the box. In connection with the lens 10, the dust cover 17 closes the box completely.

Finally, the box can be provided with a support rod 18 (Fig. 1), which consists of a steel tube. A spring is arranged in the steel tube between two outwardly projecting plastic mandrels. There are openings in the walls of the box, into which the plastic pins of the carrying bar can engage. For installation, the plastic mandrels are pressed into the steel tube and the support rod is simply snapped into the openings.
