Description

Lid lock for boxes To deal with today's shortage of wood for boxes and containers for the transport of goods of any kind, one uses so-called. Permanent boxes, i.e. boxes that are always returned as empties and then used again Serve packaging, with the purpose of taking up little space when returning it is useful to make the box collapsible. With such; Boxes the type of cover fastening plays an important role, since it is nailed up or screwing the lid onto the side walls of the lid and side walls are very damaged, so that, after a short period of use, the box for further use becomes unusable. So it depends on a lid closure to avoid damaging any parts of the crate. Lid closures for boxes have become known in a wide variety of designs. So z. B. crate closures are known in which a perforated at the ends Metal band. is folded with the ends and pushed through the box wall, whereupon, when the lid is closed, a spring hook arranged on the lid inside the box through the holes in the metal band and thereby the lid is kept closed. Such closures have the disadvantage that a Reopening the box no longer allows the box that is locked in this way therefore only find a one-time use and must be destroyed for the purpose of opening them will.

Closures are also known, which consist of two interlocking with Bayonet lock, provided sleeves exist, wherein when bringing in the second sleeve in the first sleeve pivotable latches spread apart. will. Such closures are extremely cumbersome and require precise Execution, so are very expensive to produce. They are therefore not suitable for ordinary shipping boxes, but are probably mainly used as secret locks intended for containers or suitcases.

Furthermore, screw closures for boxes are known in which a freely passing through the lid, provided with a nose on its lower part Screw bolts into a corresponding recess located on the box wall Rifle rims. This is not just a screw lock, a screw bolt is therefore not screwed into a thread of the bushing, but must counter to one Spring action in this so far down until the nose of the screw bolt reaches the position in which it passes into the corresponding recess in the sleeve Turning - can be introduced, a measure that cannot be achieved with filled boxes or can only be carried out with great effort when the filling of the box opposite Bring your crate a little bit more Yes.

Finally there are crate closures in the form of screw locks known who pursue the purpose, the screws after the boxes have been closed secure against unscrewing. For this purpose, after screwing in, lie down the screw plugs pawls or other locking devices against the thread turn, in which they were screwed, so that hereby locked boxes not without further can be reopened. So much for the latter after the closure should be opened again at all for the purpose of reuse, i.e. not are subject to destruction, reopening is only more cumbersome by means of special means Precautions possible by means of which the pawls or the like must be triggered, whereupon the screws are unscrewed «and can be grounded. It stands to reason that such closures for ordinary shipping boxes can not be used.

In order to now deal with the disadvantages inherent in the aforementioned cover closures to avoid and around one for ordinary shipping boxes. simple and cheap To create a lid lock that does not damage the box when it is opened and closed and therefore enables reuse of the box, the invention proposes one Lid closure by means of freely passing through the lid in the side walls The screw bushes embedded in the box surround the crate and are finite in their lower part Locking pawls o. The like. Provided locking screws before, in which the pivotable in the lower ring-shaped recessed part of the @ ei-schlul) schratilienl) olzen arranged Insert pawls or locks into these recesses when screwing them in and remain therein, uni after the screws have been unscrewed in itself to tip out of the screw shaft as a result of its own weight, so that the screws are secured against loss by falling out of the cover. Here it is crucial. the pawls or locks in per se known Way to be provided under the influence of springs, when the ratchets slide in or locks in the recesses of the lock! ', screws are tightened and after the screw plugs have been unscrewed, the tilting out of the Support pawls or latches.

In the accompanying drawing the invention is in two different ways Embodiments illustrated. namely Fig. i shows the lock in closed position and Fig. 2 in the open position.

Fig.; FIGS. 4 and 5 show a "cheap" c -iter embodiment.

i is the side wall of the box, and are the ones on it, for the Z @ s-: ckc of the cover storage, it is advisable to pull the reinforcement up to the cover height or hinge straps. 3 is the cover, which is used to hold screw plugs .4 has any type of holes 5, the diameter of which has been introduced through the top Metal plates 6 is reduced, so that inside the openings 5 a protruding Paragraph is created. In the side wall t introduced, provided with thread. Metal cans; serve to accommodate the screws 6, which are in their lower part with pivotable locks 8 are provided, which are when screwing in the screw insert into the sleeve 7 in the screw 6 and when you leave the thread of the Rifle ; fall out due to their own weight and stand against the by the put in the cover 3 hastily brought metal plate 6 paragraph formed and thereby insert The screws .1 fall out of the cover 3 and thus the screws are raffled Avoid with the lid open.

The swivel locks are in the carrion guide according to Fig. 3 8 under the influence of springs 9, which when the locks 8 are pressed in in the screw .1 can be tightened by screwing the screw into the threaded bushing 7 and those at releases the locks 8 when leaving the sleeve j By releasing the tension, press the latches outwards so that they get caught the locks 8 in the screw q. .excludes eats.

The closure according to the invention can also be used for metal boxes Find or similar use.
