Description

Shipping box with theft-proof lid lock. The invention relates to a thief-proof type of closure for shipping boxes, namely a thief-proof Lid lock with built-in electric bolt or lock inside the box, which can be opened and closed by means of an electric current. To the supply line a needle contact is used for the current required for opening and closing, which is inserted through small contact holes made in one of the box walls and thereby completing a circuit. The used electrical Latches or locks of this type are no longer new. The essence of the invention consists in that the electric bolts or locks in connection with a needle contact come into use for the purpose of the box lid closure.

With this new type of box locks, nailing and Eliminates other damage to the crate parts, and it is therefore an unrestricted one Duration of use guaranteed with a completely theft-proof lock of the boxes. Other types of closures for boxes, such as iron, wire and internal closures Bending the nails, can be easily opened and re-opened without leaving any marks are closed, while with the present closure only very small needle-thin There are contact holes that were spread with a putty of the same color as the box, can no longer be found without a template and are therefore the safest of all Give a guarantee against unauthorized opening.

In the drawing is an embodiment of the subject matter of Invention brought to the representation, namely show: Fig. I a partial view of the opened box (openwork interior view) with lock and supply line plus contact screw, Fig. Z a partial cross-section of a box wall with contact screw and inserted Needle contact, Fig. 3 the needle contact: with stranded wire and thread mount, Fig. 4 the box ready packed for dispatch.

All the edges of the boxes in question are mortised and glued. The crate lock consists of an electric bolt or lock a, which is screwed to one of the inner walls. The lid b is a sliding lid, which moves in the fold c. The cover labeled d is the actual one Cover, which is screwed onto the all-round support strips e by means of screws will. This creates a small space between the two lids, which It is therefore provided so that the sliding cover never gets lost or blocked can and thus always easy opening and closing is ensured. The gap can be used to receive letters, invoices, etc. Under the bar e is the supply line f for the current, and it ends on the one hand in the Contact screw g, on the other hand in the bolt or lock a. The second lead of the current happens in the same way, and therefore the contacts g can be attached at any point. Such a contact is shown in Fig. 2, namely, h shows a part of the box wall in which a recess i is let into is, for receiving the insulated wire f. This wire ends in the contact screw g and is clamped between two washers k by means of this screw. If the contact is attached to another point of the box, where the supply line cannot be hidden under a ledge, a box will appear on this side of the box Piece of veneer glued on (see Fig. 2).

If the needle contact 1 is now inserted into the Inserted the box wall, the contact needle l hits the screw g. Will with the contact needle in the same way by applying a second template move the second contact screw g, this closes the circuit, whereby the bolt or lock tongue n is withdrawn and the outer box lid b can be pushed open easily.

As a power source for the power required for opening and closing can serve a flashlight battery. The threaded socket o is used for this purpose screwed into a flashlight case. Other elements or by means of Bell transformers stepped down heavy current are used.

The goods are packed as follows: The goods to be shipped are packed in the lower box space q. The cover d is then screwed onto the strips e. Then the documents or the like to be sent are inserted and the cover b is closed. Now the two protective corners r and the iron straps s are screwed on, the collar parts located on the outer cover end in loose tabs t, but are otherwise riveted to the cover. As soon as the box is turned slightly onto the lid side, the bolt or lock tongue? A jumps automatically into the recess in the sliding lid b and can only be restored with the help of a 3.5 to 5 volt current be opened. However, if goods are to be packed in the box that do not allow the box to be turned over, the lock of the box can also be closed by means of an electric current: the procedure is the same as when opening the box, namely by applying the button to close it required template for the contact screws in the closing circuit.

If the box is now ready for shipping, the needle-fine ones are still fine The contact holes were spread with a putty of the same color as the box, whereupon itself the initiate without using the template after some time the individual contact holes no longer finds. Thus, the greatest possible protection against unauthorized opening Security required.

The placement of the individual contact holes is different for each box. There are also deviations in the design and use of the electric bolt and Locks provided.
