Description

Lid lock for wooden boxes There are lid locks for wooden boxes known in which closure parts in slots or notches of the lid or the box intervene; mostly are (read hook-shaped or toggle-like acting Parts that consist of relatively strong iron sheets or wires. To other proposals the closure is made by twisting wire loops, which are attached to protruding parts of the box and the lid against the Tighten the box. Such closures require a lot of iron and make the box unnecessarily difficult. They also interfere with the handling of the boxes because the protruding ones Easily share on other boxes or goods while moving on the loading floor caught. This can also damage the closures, so that the contents the box is not properly secured. The present invention relates to a Lid lock for wooden boxes, which not only requires little iron or the like, but also avoids all protruding parts both outside and in the packing area of the box. Closing the box is extremely easy and can be done with known Perform tools quickly. The closure is completely firm and can also easily protected by seals or other security measures.

In the accompanying drawing, an embodiment of the invention is shown, namely Fig. 1 shows the closure in a view, Fig. 2 in cross-section, Fig. 3 in a plan view and Fig. 4 in a perspective view. Fig. 5 shows the wire loop that is used for closing. As the figures show, reinforcement strips c and d are attached to boards of the cover a and the side wall b. Of course, you can also refrain from attaching these reinforcement strips if you choose the crate boards accordingly. In the interest of saving wood, however, it is more practical to choose the boards relatively thin and to reinforce the edges with strips.

In these strips, notches e are now made, which are exactly opposite, as can be seen in particular in Fig. 4. These notches can be produced by milling, sawing or in any other way. They are distributed on the lid and on the edge of the box at such intervals that depending on the size of the box, the desired number of locking points is available.

Over these notches e, webs f are now arranged, which are expedient consist of a U-shaped bent nail (staple). This cramp will like it in the manufacture of boxes is common, mechanically or even by hand so over the notch e nailed into the bar so that the cramp tips are sufficiently firm Provide support for the bridge part of the staple. But you can also use webs in a different shape over the notches.

Now, as the figures show, a wire loop is used g placed over the webs f so that they are fixed by twisting the loop ends be pulled together. Thereby the lid a is on the side wall b of the box pressed so that the box is closed.

The wire loop can be formed from any piece of wire. However, it should be useful to use prepared wire sections like them are shown in Fig. 5. As this figure shows, there is a wire loop from a hairpin-shaped piece of wire with bent ends. These ends are hooked into a known braid device, as it is, for. B. for closing of sacks or the like. Is common. By pulling on the plait apparatus, the ends are the loop twisted together so that the clasp made is like this especially the Fig. z can be seen. But it is not practical to remove the wire ends, as shown in Fig. a. Rather, you can simply push it in push the ends of the wire loop into the notch so that no parts are left of the lock protrude over the box.

It should be noted that the usual braid devices are relatively Have large pegs over which the ring-shaped ends of the wire are hung will. Such a configuration is not appropriate for the present invention, because then the notches e must be relatively wide. The inventor has therefore changed the braid apparatus in such a way that the ends of the wire loop only slightly are bent and can be hooked into a slot in the braided apparatus. This ensures that the notches only need to be narrow to the To be able to introduce wire loop. This has the great advantage that the wire loop after closing the box in the notch can move only a little.

There is now no difficulty in getting the ends of the wire loop through to secure a seal, so that the closure at the same time to a sealed closure can be designed.

Another advantage of the fastener is that you can get in a lot can easily cover the notches with strips of paper with security features, Company details or the like can be printed; as long as these paper strips are intact the box cannot be opened without authorization.

The invention is suitable for all types of wooden boxes; she is not only usable for solid, but also for detachable wooden boxes.
