DE8511421U1 - Automatic locking device, in particular for window shutters - Google Patents

Description

The innovation relates to an automatic hold-open device, especially for shutters, with a one stop and one catch ~ hook having carrier, the catch hook pivotable against spring force on its the stop averted back a run-up surface for the between Stop and catch hook lockable store od. Like. Forms.

Known locking devices are equipped with catch hooks rotatably mounted on the carrier, which, due to a correspondingly inclined run-up surface, are pushed open by the rear edge of the loader when the shutter is opened and then, after engaging around the lower edge, hold the shutter between the gauge and the rigid stop , Zur Ar, -

There is a matching of the catch width to the size of the shop specially designed catch surfaces, swivel locks, sliding guides and the like for the catch hooks. or also slidably mounted stops on the carrier. All of these well-known locks with Their rotatable and / or displaceable parts are, however, affected by weathering, corrosion, Soiling and the like are prone to failure, often because of jamming and similar inadequacies Difficulties especially when opening and can only be compared in addition elaborate and expensive to manufacture.

The innovation is therefore based on the task of providing a locking device of the type described above to create, which allows a simple and cheap production, distinguished by its resistance and Functional reliability and a firm, backlash-free hold of shutters of different thicknesses Od. Like. With the most convenient release option, guaranteed.

The innovation solves this problem in that the catch hook or via a resilient tongue. Like. On Attacks carrier and a resilient stop is provided. Due to the lack of their own rotating or Slidably mounted parts can malfunction from the outset due to weather influences, Corrosion or contamination can be avoided, and there is little effort manufacturable locking device. The catch hook acting resiliently on the carrier also allows one of the bottom edge of the shop independent assignment of the lock to the shop to be held and the resilient compliant stop brings an automatic

Adjustment of the. Locker to the given shop thickness with it. The stop itself is effective additionally due to its resilient properties as a damper or buffer for the store and leads to a gentle gripping and holding of the load. When releasing the store, we are then the one so pre-tensioned spacers as a push-button that opens the store as soon as the catch hook is opened by hand is, repels and brings it out of the area of the arrester, which is convenient, even with one hand Handling allowed.

In a particularly advantageous embodiment of the innovation, the carrier, catch hook and stop are Made in one piece from plastic, making a particularly simple and cheap mass production of the Locking device is possible. Any appropriately solid and resistant, Resilient, non-aging plastic.

To give the stop a spring property that is sufficient also for good damping and pushing-up effects to lend, according to the innovation, the stop in the form of a spiral or helical spring designed so that even if the stop is formed in one piece on the carrier, it is made of stiffer plastic gives the required resilience.

In the drawing, a lock according to the invention is shown, for example, on the basis of a schematic Side view illustrates.

A particularly simple, easy to manufacture and yet functionally reliable locking device for Shutter 1 consists of a carrier 4 anchored in a wall 3 via dowels 2 or the like, which has an attachment

blow 5 and a catch hook 6 has. Carrier 4, stop 5 and catch hook 6 are made in one piece from plastic, which is not only sufficiently strong, tough and resistant to aging, but also has elastic properties. Stop 5 forms a kind of coil spring, to be resiliently, and the Ken with his Rpt ~ a ramp surface 6a forming catch hooks 6 is formed over a resilient tongue 4a on the carrier 4 so that it can come to erfor sary en hook movement. ~

When the drawer 1 swings open, the lower edge of the drawer 1a hits the ramp surface 6a from the outside and presses the catch hook 6 down until it is due to the restoring effect of the resilient tongue 4a pops up and clicks into place. Simultaneously with the actuation of the catch hook 6, the shop 1 also has the Reached stop 5 and pushed it back according to the thickness of the store, the resilient properties of the stop 5 exert a buffer and damper effect on the store. The compliance of the stop 5 also ensures that the catch hook 6 for reaching around the bottom edge of the shop 1a and so that enough space is cleared for proper locking and that the drawer after locking 1 is held free of play between the stop 5 and the catch hook 6 regardless of its strength. The locking device is released by simply manually pressing the catch hook 6 into its The release position indicated by dashed lines, this pressing down by a catch on the catch hook 6 provided handle 7 is facilitated, in which free position the drawer 1 its holder loses and swing forward over the catch hook 6

can. Due to the release of the drawer 1 by the catch hook 6, the can also get through the compression with the loading biased stop 5 again up to its also dashed lines Relax indicated starting position, whereby the store 1 automatically from its holding position is pushed out and is released from the arrester without manual intervention.
