Device for matchboxes to limit the stroke of the drawer. Patented in the German Empire on November 13, 1925.

It has already been proposed to make arrangements on matchboxes to which causes the drawer to fall out or open it incorrectly Page is prevented by stops are arranged in the area of the drawer. In order to prevent the wooden wall from splintering and breaking out, it has already been proposed has been, for these purposes, a tab provided with a plate in a parallel

to insert the slot arranged in the direction of the grain of the box cover. ·

According to the invention the tongue is now available by a narrow web with the outer plate in conjunction, so that it can be rotated 90 ⁰ slightly after insertion into the slot.

The practical realization of this idea is expedient so that the new device is mainly made of a resilient sheet metal, from which the part serving as a stop is punched and bent downwards. This longitudinal member is then in the fibrillation, which is located at each matchbox perpendicular to the longitudinal side, is ejected and the resilient sheet with the stop 90 ^it is rotated. As a result, on the one hand, the stop when pulling out the box is very favorable because the pieces of wood touching it slide past in their longitudinal direction without any friction, on the other hand, because the stop is brought in at the moment when the box is open

& 5 is pressed against both of its long sides, resulting in an upward curvature of the lid, which returns to the level position when the box is relaxed, the prongs of the stop are pressed into the box top from below and held in this position by the grooves in the sheet metal plate. As a result, the stop within the box is absolutely secured in its correct position and against falling out. Since the casing of the matchbox is only in the form of a short one, lying in the direction of the grain

. If the slot is injured, fragmentation of the sensitive housing is almost impossible.

These processes take place when the box is unopened and filled.

An embodiment of the invention is shown in the accompanying drawing, from which the production of the stop and its attachment can be seen at the same time is.

The stop is made from a sheet metal plate a (Fig. I) of any material, in that this sheet metal plate, as shown in Fig. 2, expediently receives two grooves b and a T-shaped cutout c in a single punching process. As can be seen from Fig. 3, this section is bent downwards. This completes the stop and it is now only necessary to attach it to the matchbox. For this purpose , a slot e is provided in the housing d of the matchbox, as can be seen from Fig. 4, the length of which corresponds to that of the cutout c. Since this slot lies in the direction of the grain of the wood, it can be made very easily without the box splintering. The device α is now pressed onto the box in accordance with the arrows / shown in Fig. 4, the cutout c passing through the slot e . The plate a is then ^{rotated through 90 °} in such a way that, as can be seen from Fig. 5, the section c , which was previously parallel to the grain, is now perpendicular to the grain. The holding of the plate a in this position takes place through the grooves b, which give the plate α and the underlying cutout c a resilient locking. Fig. 6 shows a section through the matchbox in the direction of the final position of the section c. It is useful to provide small spikes g on the plate a , which have the following purpose:

When the stop penetrates, the lid bulges upwards Relaxing the box returns to the level position. This will then the prongs of the stop pressed into the top of the box from below and the sheet metal plate as a result, absolutely retained in their position. The prongs also bring relief the passage materials of the attack with it.

It can be seen from this that the stop effect of the cutout c takes place in the form that is favorable for the distribution of forces. Every force component acting on bending is eliminated and the strength of the entire device is thereby greatly increased.
