DD223490A1 - RETRACTABLE UNLOCKING DEVICE FOR LEVERAGE - Google Patents

Abstract

The invention relates to a nachruestbare unlocking device for push rod, especially at gates of garages with a second input. The invention aims at always safe and fast opening of locked, freely mounted thrust loads from the side of Gestaenges. The task of structurally designing the unlocking mechanism of a thrust linkage so that the gate can be opened quickly and at any time from the side of the linkage and the existing linkage can easily be retrofitted. This is achieved by paralleling the already existing link, but not to the point A second, forcibly guided sliding latch is attached to the locking reaching bolt, which takes over the locking in the ground. The invention may find application in the production of Schubgestaengevorrichtungen as well as Nachruestvariante for existing thrust linkage. Fig. 1

Description

Stahnsdorf, d. 29. 03. 1984-

Title of the invention

Equipped unlocking device for push rod

Field of application of the invention

The invention relates to a retrofittable unlocking device for push rods, especially in one-sided operated Yerschlußvorrichtungen.

Characteristic of the known technical solutions

They are closures with push rods on G-ark swing gates. in the locked state, they are either not at all open or can only be opened with a key. In a suddenly occurring G-efahr situation (outbreak of a fire, etc.), the unlocking is relatively complicated and time consuming »Even with locks with a movable cylinder has the disadvantage that for unlocking a key is also required from the inside of the door.

There are many possibilities of locking operation, such as by a latch bolt (DE-PS 1 063 927), by opposing locking bars (DE-OS 1 553 617), by angular zuein-

otherwise arranged espagnolettes CDS-OS 1 553 563), by a Yerschluß with a single drive rod and pivot bolt CDE-AS 1 291 65o} or by an espagnolette closure, combined thrust and traps (DS-PS 1 286 934).

In DE-PS 1 171 78o a drive rod lock is described, which can be used except for overhead doors for rotary and folding doors. In the DR-PS 388 255 from 1924 a lockable sliding bolt is described, which can be opened and closed on both sides, but only with a key.

A disadvantage of all the solutions outlined is that in case of danger the gates with push rods are not open or only with a key destructive from the inside.

Object of the invention

The aim of the invention is a door direction for unlocking freely mounted push rods, which allows unlocking without a key on the side of the push rod in dangerous situations occurring.

Presentation of the invention of the invention

The object of the invention is to make the unlocking mechanism of a push rod retrofitted constructive so that the push rod at any time without the presence of a key from the side of the linkage to unlock and also the existing push rod easily retrofitted with the unlocking mechanism.

According to the invention the object is achieved in that parallel

for already existing, but · shortened thrust bolt a second, positively driven sliding bolt is attached and with the help of this bolt, the original length of Yerriegelungsvorrichtung is restored.

The second sliding bolt is connected to a tension spring. Against the force of this tension spring. This sliding bolt can be raised by hand and thus a release from the side of the push rod from completed. For re-engagement, the second latch is chamfered at its lower end.

embodiment

In the flat version, shown in the jig. 1 and 2, the sliding bolt (3) via a rotary handle (1) and lock box (2) is actuated. In the embodiment of this invention, this sliding bolt (3) does not reach the ground, but was shortened. A second bolt (4-) mounted in parallel thereto is fixed in its thrust direction by two lifting straps (5) screwed or welded onto the sliding bolt (3). Between the lower guide plate (5) and a pin (7) on bolt (4-) a tension spring (8) is mounted. This tension spring (8) causes the locking of the bolt (4) in the G-aragen floor, the gate (6) is closed. The latch (4-) is bent at its upper end and lies with the bent portion on the upper Siihrungslasche (5) · To open the gate (6) from the inside, the bent portion of the bolt (4) is pulled up · Sin slip out out of the 3 contact tabs (5) prevents the screw (9) ·

In the second variant of solution shown in FIG

the sliding bolt (1o) is also shortened. · Via this sliding bolt (3), a pipe (11) is pushed, which takes over the function of the additional bolt. The pin (12) fastened to the sliding bolt C1o) ensures that the pipe (11) is held in its working position after its assembly. The compression spring (13) keeps the pipe (11) in the closed position again and again.
