Description

safety lock

The present invention relates to a securing element for the slide of a zipper according to the preamble of claim 1.

Such a securing element serves to secure a zipper in the closed state such that no unnoticed opening of the zipper is possible. For example, such secure zippers are used for the closure of folders or bags, which should be opened only by the addressed recipient. In order to indicate an eventual opening on the feed path, individualized security elements, such as seals, for example, are attached to the slider of the zipper in the closed position, which need to be removed to open the zipper. This can be ensured that the folder resp. Bag is unopened resp. an opening attempt resp. an opening made is immediately and obviously indicated by the absence or damage of the security element.

In DE 2 361 440 such a security device for a zipper is described, in which a deformable male part with locking portion and detachable from the headboard the slider resp. the pull tab of the slide locked in the lock part of the securing device. By separating the head part of the locking portion of the male part, the lock of the slider can be canceled. there However, the male part is divided and the items must be disposed of separately and removed from the lock part.

The object of the present invention was to provide a securing element for securing the slider of a zipper in the closed position, which can be used easily, quickly and safely. Another object was that the fuse element can be used multiple times. This object is achieved by a

Secured element correspond to the features of claim 1. Further, inventive embodiments result from the features of further claims 2 to 7. The fuse element for securing the slider of a zipper in the closed state of the zipper according to the invention comprises a housing shell with a pivotally mounted on the housing shell lid, wherein the housing shell one end of the zipper receives or encloses and has means for receiving the slider, which correspond to the lid so that in the closed state of the lid, the slider is fixed in the fuse element. Next, a closure member is formed, which has connectable with the lid locking or clamping elements and which has latching tongues which engage in closing the lid in corresponding latching cams of the housing shell and thus keep the lid closed, wherein the Closing part is constructed in one piece from several members, which are interconnected by webs.

By this arrangement, the slide of the zipper in the closed state can be easily and securely fixed by closing the lid in the fuse element. For this purpose, the securing element is arranged at the end of the zipper and connected to this, to which the slider comes to lie in the closed state of the zipper. Without opening the lid of the fuse element, the zipper can not be opened. For this purpose, however, the closure element must be destroyed because its locking or clamping elements resp. Locking tongues in the lid resp. locked in the housing shell resp. are clamped. Such destruction, especially partial destruction, is obvious and thus the manipulation of the zipper. The webs of the individual members or segments of the fuse element form a rigid connection in the original state and thus a dimensionally stable securing element, which serves as a locking element between the cover and the housing. To open the lid, individual webs must at least partially broken or at least be broken, whereby the locking element loses its shape and thus the elastic locking effect is lost. Nevertheless, the individual members remain resp. Segments of the fuse element connected to each other, so that the fuse elements remains in the destroyed state in one piece and thus easy to handle. For example, the webs of the closure part are dimensioned such that they break or break under load before the connection of the locking tongues or locking elements is released. Thus, individual limbs rep. Segments of the closure member partially separated from other members, without that the overall connection of the members is separated, ie the closure part still remains in one piece. By separating individual webs, however, the locking element and locking tongues can be released from their anchors and thus give the fixation of the cover with the housing shell free, so the lid can be opened and thus the slide of the zipper can be moved freely again. Advantageously, the closure part remains as a single piece and can therefore be easily disposed of. When separating individual webs, the manipulation is immediately apparent by releasing the locking connection, so that such manipulation is also easily detected.

For example, the closure part has a substantially Y-shaped configuration, and a latching tongue is arranged at each of the two ends of the two upper legs and the end of the individual lower leg has an upwardly bent or protruding tongue. This shape of the closure part allows the securing element to be opened simply by pulling on the tongue. Due to the lever action of the tongue, the locking elements of the closure part are separated from the tongue and thus the locking connection of the closure part with the lid is released. This makes it easy to open the lid, which advantageously receive the closure part in one piece remains and can be removed as a single part of the now open fuse element and the slide released from its holder and the zipper can be opened. In a further embodiment, the underside of the housing shell is connected to a base plate. Thus, the housing shell can be connected inextricably and stably connected to the zipper, resp. with the material, for example, the bag equipped with the zipper.

In a further embodiment of the invention, the lid pin respectively. Rods, which in partially open eyelets resp. Retaining tabs of the housing shell are rotatably mounted. For a simple pivotal connection in the form of a hinge between the cover and the housing shell is realized, which may also allow replacement of the cover in the event of damage.

For example, all components of the fuse element made of plastic. Thus, the fuse element can be produced inexpensively in large quantities and high manufacturing accuracy and it also has a robust construction.

In a further embodiment, the lid has an opening for receiving the closure part. Thus, the closure part can be easily from the inside of the

Insert the lid into the lid and still project outwards resp. is optimally accessible from the outside for the opening process. Further, a bag is provided with at least one opening, which is equipped with a zipper for closing the opening, in which according to the invention one end of the zipper is equipped with a securing element according to the present invention. Thus, a container for the transport of confidential goods, such as documents created in which an unauthorized opening attempt or unauthorized opening is clearly displayed, the backup can be done very easily and quickly.

Embodiments of the present invention will be explained in more detail below with reference to figures. 1 shows the view of the individual parts of a securing element according to the invention;

FIG. 8 shows in more detail the plan view of a closure part according to the invention; FIG. 9 shows the partial view of the underside of the front region of the closure part according to FIG. 8;

Fig. 10 shows the view of the arranged in the housing shell resp. snapped-in closure part according to FIG. 8; and FIG. 11 shows the view of an alternative embodiment of the closure part according to FIG. 8.

In Figure 1, the individual components of a fuse element according to the invention are shown with the housing shell 10, the cover 20, the closure member 30 and the base plate 40th

Figure 2 shows schematically the arrangement of the inventive securing element 1 of Figure 1 at the end of a zipper 2 of a bag 3 in the closed state. The slider 4 of the zipper 2 is completely disposed within the securing element 1, so that it is neither visible nor accessible from the outside.

FIG. 3 now shows how, with an opened securing element 1, the slider 4 of the completely closed zipper 2 is positioned in the housing shell 10. Here, for example, the eye 5 'of the pull tab 5 of the slider 4 via a pin 11 in the ground the housing shell 10 is pushed. Thus, the slider 4 is fixed in this housing 10 in this closed position.

By folding down the lid 20, the securing element 1 is closed, as shown in Figure 4. The lid 20 is locked by pressing with the housing 10, as will be explained in more detail below. Thus, the inside of the lid 20 passes respectively. the closure member 30 into abutment with the free end of the pin 11 in the housing shell 10, whereby inadvertent or autonomous release of the slider 4 is prevented from its closed position.

The cover 20 is advantageously mounted in the housing shell 10 such that it remains positioned without pressure load in the open state at an angle relative to the housing shell 10. Thus either the closure process, which has not yet taken place, is visually readily apparent or a defective closure part 30, which can not fix the cover 20 in the closed position, is also displayed. The now so closed fuse element 1 can only be opened by the closure member 30 is released by raising the flag 31 from its anchorage on the lid 20, whereby the lid 20 can be opened again and thus the slide 4 is released and thus the zipper 2 are opened can, as can be seen from Figures 5 and 6.

After opening the lid 20, the closure member 30 advantageously remains in one piece and therefore can be easily and completely removed from the housing shell 10, such as this is shown in FIG. But this is the closure member 30 functionally destroyed and can not be used again for a renewed closing of the housing shell 10. In Figure 8 is the detail of the supervision of a

Shutter member 30 of the preceding figures shown. Here, the one-piece construction, consisting of several interconnected via thin webs links, clearly visible. In this case, the flag 31 is formed at the free end of the central base body 32. At the other end, two quarter-circle-shaped locking segments 36 are laterally connected via webs 37 to the base body.

These locking segments 36 are dimensioned such that they conform elastically against a lid 20 formed on the nose 21 during insertion of the closure member 30 in the lid 20, respectively. engage.

Further, a latching jaw 34 is arranged on each side of the base body 32, which in turn is connected to the base body 32 via webs 38. These locking jaws 34 also enclose the outside of the respective

Locking segments 36 and are connected to these also via webs 39. At the free ends of the locking jaws 34 resilient cam 34 'are arranged, which engage resiliently in corresponding retaining means 12 of the housing shell 10 and thus the locking member 30 with the housing shell 10 latching connect, as can be seen for example from the illustration of Figure 10. In FIG. 10, the closure part 30 is shown locked in the housing shell 10, with the cover 20 open. By the arrangement of the resilient cams 34 'at the free ends of the locking jaws 34, they continue to serve when opening the lid 20, the opening forces on the webs 37, 38, 39 and 39' to transfer and thus break it. Thus, an opening of the lid 20 without visible destruction of the webs is not possible, thus precluding a manipulation of the closure.

Further, for example, in the area between the locking jaws 34 and the flag 31, additional holding cams 33 are arranged laterally on the base body 32, which are likewise connected via webs 39 'to the base body 32 and are in clamping connection with the cover 20.

These additional retaining cams 33 can be arranged, for example, directly as an extension on the respective latching jaw 34, as shown in FIG. 11. In this case, the locking segments 36 may be formed as a semicircular single segment.

The webs 37, 38, 39 and 39 'between a single segment of the closure member 30 are now dimensioned so that they in attempting to open the

Cover open 20 individually or at least buckle before the connection between the closure member 30 and the cover 20 or the housing shell 10 is released. This is achieved, inter alia, by the arrangement of the cams 34 ', which break the webs by their leverage before their locking action is released. Thus, individual webs remain as connecting elements between the individual members of the closure member 30, so that the closure member 30 remains in one piece, but the originally stiff Structure of the closure member 30 is broken. Thus, the attempt of opening the lid by correspondingly broken webs 37, 38, 39 or 39 'is already displayed, without actually an opening has taken place. However, the damaged closure part 30 can no longer be used, but must be replaced by a new closure part.

For the intended opening of the closure, the closure member 30 by lifting the flag 31, as shown in Figure 5, partially broken, causing the cams 34 'of the locking jaws 34, respectively. let the locking segments 36 release their lock and thus the lid 20 can be opened.

Thus, the fuse element can be used multiple times, it must be replaced after use only the used and thus destroyed closure member 30 by a new closure member 30, which thus performs a key function.

The great advantages of the inventive construction are the simple structure, the simple and quick operation, which can be done with one hand majority, the reliable display of manipulation or opening, the security of only one use of each closure part and the robust construction of the lid and housing shell.

Due to the possibility of preparatory use of the closure member 30 in the lid 20, the effective closing operation, ie securing the tab of the closed zipper, easy, reliable and especially done quickly.
