Unlock button for emergency exit door lock. - Limited validity in respect of certain goods.

The invention relates to an opening button for the lock of the emergency exit door 5, the button comprising a handle and a rotating sleeve associated with one end which engages the lock spindle so that when the handle is turned the lock spindle rotates with the rotating sleeve and moves after.

The emergency exit buttons shall be such that, in an emergency, the door can be easily opened, even if there is an obstacle 15 which makes it difficult to open the door. In many cases, the removal or breaking of such an obstacle is arranged to trigger an alarm so that emergency exits are not used in normal situations. One commonly used solution is such that there is an obstacle below the handle which prevents the handle from turning, which, however, can be turned aside by the use of force, whereby the alarm is triggered, or which can also be turned aside with a key without triggering the alarm. However, this device is' · '' difficult to use in an emergency if you don't know how the device is' 'meant to be used. In addition, the device is expensive.

25 * ί “· German application DE-3818 538 discloses: a similar release button in which opening the seal or: 1 · 1: breaking allows the handle to be turned. After use, the release button must be resealed, where j ·. 30 additional work is caused when unauthorized openings cannot be avoided unless the seal is so strong as to interfere with opening in an emergency.

: t_: Another previously known device is a breakable plastic hood for use with the button 35. However, practice has shown that they do not prevent unauthorized passage through emergency exits, in which case broken plastic domes must be constantly renewed.

The object of the invention is to provide an improved emergency exit opening button which effectively prevents improper passage through the emergency exits, but is nevertheless extremely easy to use when it is necessary to pass through the emergency exits and is also simple in construction and inexpensive.

This object is achieved by the invention on the basis of the features set out in the appended claim 1.

Advantageous details of the structural implementation of the invention are set out in the dependent claims.

In the following, one embodiment of the invention will be described in more detail with reference to the accompanying drawings, in which Figure 1 shows an opening button according to the invention seen from the side to be attached to the door 20; Fig. 2 shows the same button in a sectional view and Fig. 3 shows a section taken along the line A-A in Fig. 2.

• ·: At one end of the handle 1 there is a rotating sleeve 2, the inner sleeve part 2a of which is around the locking mandrel 3. When the locking spindle 3 is turned when the handle distributor 1 is turned, the locking tongue 30 (not shown) moves to the open position.

• · · • · ·

The pin 4 passing through the locking mandrel 3 engages the opening 5 of the sleeve part 2a, which is elongated in the circumferential direction. In this case, the sleeve part 2a has a certain free angle of rotation (e.g. 18 °), ....: 35 during which the spindle 3 does not rotate with it. As a result .... the handle 1 has a certain free pivoting movement (e.g. 18 °) during which the locking spindle 3 does not rotate or move the locking tongue.

Attached to the inner surface of the outer circumference of the rotating sleeve 2 is a microswitch 6 which cooperates with the protruding end of the pin 4. The microswitch 6 is positioned so that when the handle and 1 are turned e.g. in a horizontal position, the pin 4 hits the microswitch 5, which trips the relay 10, which in turn switches the current from the battery 12 to the buzzer 11, which beeps. At this point, the spindle 3 is not yet twisted, so the lock is fully closed. Hearing the beep usually interrupts the continued turning of the handle 1 and the attempt to open the door. This can be further ensured by a barrier limiting the rotation of the handle 1, which can be overcome if necessary by applying sufficient additional force. In the case shown, the inner surface of the sleeve 2 is provided with a suitably positioned recess to which the spring-loaded ball 13 adheres. The spring 15 and the ball are retained in the base plate 7. The receiving recess of the ball 13 restricts the rotation of the handle 1 at the latest in a situation where the continuation of the rotation would start to rotate the locking spindle 3.

Between the base plate 7 fixed to the door and the rotating sleeve 2 there is a spring 9 which holds the handle 1 in the upper position shown in Fig. 1, which is the starting position of said free pivoting movement. Said free pivoting movement thus takes place against the force of the spring 9, and when the grip on the handle 1 is released, the position of the handle-25 returns to the upper position. The buzzer alarm may end after a certain * *** * time, or it may remain on until it is acknowledged and, if necessary, the alarm may also be sent remotely::: to the control center.

30 The alarm can be acknowledged with the key 14 by a rotary on / off switch 15, with which the alarm can also be bypassed • · · so that it can pass through the door without an alarm.

The handle 1 can be made of a suitably sized tube, whereby it creates a receiving space for the relay 10, the buzzer. 11 and 12 for the battery.

The invention is not limited to the above push button structure and handle design. The handle can be, for example, a long rod with an opening button structure as described at both ends, but with only 5 alarms. In this case, the handle bar moves in the same direction and pivots the pivot arms at both ends thereof, which correspond to the pivoting handle 1. The door is then opened by pressing the handle bar, which causes the pivot arms to pivot.
