Zip puller

The invention relates to a slide fastener, the one Has body with guideways for zipper teeth.

In known zipper sliders, the locking of the slider on the zipper is in the closed position of the zipper by causing a nose between the staples or teeth of the closed zipper is used, which is formed or arranged in suitable queens of the lever-shaped pulling eye of the slide fastener is. Such a locking is not reliable, however, since even slight stresses or movements of the lever-shaped pull handle enable unlocking and thus allow unwanted opening of the zipper.

In order to avoid these drawbacks, it has been proposed to use For safety reasons, the lever-shaped pull eye with a removable To provide lock that engages in a suitable fixed slot in the closed position. This kind however, it is not applicable to all types of zip fasteners and often interferes with the locking mechanism aesthetic impression of the zipper closure slide see -

'The invention is based on the object To avoid disadvantages and to design a slide fastener of the type mentioned in such a way that it can be operated without impairment its appearance can be reliably and securely locked in the closed partition.

The aforementioned object is achieved according to the invention by that a key-operated locking device is housed in the slide body.

A slide fastener designed according to the invention is characterized in that the slide body has a Has cylindrical recess, which with the inner Pührungsbahnen communicates via a slot in which a suitable locking plate is pivotally received. The swiveling one Locking plate is equipped with a nose or the like. That is between two adjacent teeth or clamps of the zipper closure can intervene. In this locked position and a

The locking plate is released by a base surface that is inclined to the cylinder axis of a cylindrical block transferable when the in the cylindrical recess recorded cylindrical block is rotated by means of a removable key about its cylinder axis.

body 1 there is a cylindrical recess 3 (Fig. 2), which communicates with the inner guide track 2 via a slot 4 which is transverse to the longitudinal axis of the Zipper is arranged and in which there is a locking plate 5 (Fig. 3), 'around a pin or tenon 6 is pivotable, which extends in the longitudinal center line of the slide body 1.

At the lower end of the locking plate 5 there is a rabbit 7, which is designed so that it can engage in the gap between two adjacent teeth of the zipper or after corresponding pivoting about the pin 6 in the direction of the two arrows 8 emerges from the gap and into a Exemption is transferable.

The pivoting movements of the locking plate 5 are caused by rotation a cylindrically shaped block 9 which is fitted into the recess 3 and in this around its Cylinder axis is freely rotatable.

As FIGS. 3 and 4 clearly show, the .der is cylindrical Block 9 equipped at the lower end with a base surface 10 inclined to the cylinder axis, in which a longitudinal groove 11 (Fig. 4) is located, which is used to receive the upper edge of the locking plate 5 to this or also to lock the block 9 in two fixed end positions, the

can each be reached by turning by 180 ° and from which one brings about the locking position and the other the release of the locking plate.

The cylindrical block 9 is constantly resiliently pressed against the locking plate 5 by means of a spring 12. The spring 12 rests on the upper end face of the block 9 and is supported on the lower surface of a cap 13, which the cylindrical recess 3 closes at the top. The function of the spring 12 is to provide sliding contact between the upper end edge of the locking plate 5 and the inclined base surface 10 of the cylindrical block maintain.

The cylindrical block 9 can be rotated by means of a removable key 14 (FIG. 10) and faces this Purposes a slot-shaped recess 15 opening out in its upper end face (FIGS. 3, 4 and 9), which in their cross-sectional shape of a double flat 16 of the key 14 is adapted. In order to be able to insert the key 14 into the recess or the slot 15 in the block 9, the spring 12 is also equipped with a central recess. The cap 13 also has a central keyhole 17, which is adapted in the shape of the key shape or the flat 16 of the key 14.

we are now on the Pig. 51 6, 7 and 8 referenced in which shows a second embodiment of the slide fastener. The structural design of the The zipper slider shown in Figs. 5-6, 7 and 8 is, corresponds to the design of the slide that is in the Pig. 1 am 4 is shown and they will therefore be the same Parts are provided with the same reference mark. The two zip sliders namely only differ in the type and manner in which the locking plate 5 can be pivoted is stored. The Pig. 5, 6, 7 clearly show that üaß the locking plate 5 is pivotably mounted on a web 18 which extends centrally across the slot 4 and is in one piece is formed on the slide body 1.

In both embodiments of the slide fastener, the cylindrical block 9 is in the longitudinal or axial direction held with play in the recess 3. The game is so big that the rotation of the block around the angle of 180 ° is below is possible under all circumstances, even if the cheese 7 of the locking plate 5 is in the current respective state of the heat seal slide or the position in relation to the zipper is so that the nose on a tooth of the Zipper meets. The key H can thereby be pulled out of the keyhole 13 under all circumstances.

However, the locking of the zipper slider is under

secured under all circumstances. It takes namely from the described state in which the nose of the locking plate on dex \ tooth of the slide fastener is, starting only a slight displacement of the slide fastener slider, occur in order to achieve that the lug ¹ 7 engages immediately into the gap between two adjacent teeth of the zipper .

It should be emphasized that the above description of the Embodiments serve exclusively to explain the concept of the invention and that further modifications and Modifications to the slide fastener are possible without departing from the essence and content of the invention by the appended Claims expressed to differ.
