DE2721650C2 - Door lock for toilet cubicles or the like. with remotely controllable, electromagnetic blocking device - Google Patents

Description

The invention relates to a door lock for toilet cubicles or the like of a stationary or mobile type with a locking mechanism, which can be operated under signal control.

Locking arrangements for door locks of the type mentioned are in the? » ^! Various embodiments are known. These are primarily purely mechanical locking arrangements that can be released on one side. Special designs of such systems are those door locks that can be operated by inserting coins, etc. All of these arrangements prevent the cabin from being used even if there are operational disruptions.

Now the applicant has already created an automatic door lock that still has the outlet Permitted from the cabin, but denied further entry. The locking mechanism is also used here Can be actuated by signal-controlled electromagnetic means, but allows the blocking to be canceled by hand, whereby the locking force is overcome.

The present invention builds on this arrangement and has set itself the task at a Door lock of the type mentioned above to block access in the event of malfunctions by remote triggering, however, to allow the exit by manual actuation until the malfunction has been rectified. The access is blocked on one side by remote triggering, while the The door can be locked, unlocked and opened manually from the other side. That is, while so far the automatic locking basically had to be unlocked by hand, is with the invention The door is also automatically unlocked. The remote-controlled locking only remains for this long in functional activity until the disorder is effectively eliminated.

This object is achieved by the measures indicated in the patent claim.

The invention is described below using an exemplary embodiment and shown in the drawing. It shows

F i g. 1 is a front view of a car door provided with the invention;

F i g. 2 shows a sectional drawing of the detail X according to FIG. 1 and

3 shows a section along the line AA according to. On the front of the car door 1 there is a recess 2 in a known manner, into which the so-called door lock 3 is embedded are connected, mutually rotatable. Both parts interlock like a claw coupling, but they allow a radial rotation up to a certain angle. This possibility of rotation is necessary in order to

to be able to open the door from the inside to be able to open the door from the inside. The twist angle between the outer Door handle 11 and inner door handle 12 and the coupling bolts 4, 6 must be equal to or greater than the maximum angle of movement of the inner door handle

-oeim opening the door. Holds when the lock is not blocked the leg spring 9 the inner and outer door handles 11, 12 in a parallel position, while through the pin screw 13, the outer door handle 11 is locked axially, but the required rotational movement opposite the coupling bolt 6 is still possible

To lock the outer door handle 1 i is now at the appropriate distance from the door lock in a recess of the door leaf 1, an electromagnet 7 is arranged with a bearing frame 8. This magnet 7 carries by means of a rivet 25 or the like a locking sheet 10 with a nose 14, which in a groove Ϊ5 of the outer Door handle 11 can intervene. The handle 11 is blocked as soon as the electromagnet 7 is energized is supplied by the transmitter of the fault reporting device (not shown). This will tighten the anchor and the locking blade 10 firmly connected to it moves up and engages with its nose 14 in the Groove 15 of the handle 11. This is blocked and as long as the magnet is energized. The cabin cannot be accessed by a user from the outside more to be entered.

However, if the blockage occurs at a time when there is still a user inside the cabin is located, this can easily leave the cabin, because the inner door handle can be due to the Coupling pin assembly 4, 5, 6, 7 can be operated. Now to the cleaning or repair staff To enable access to the locked cabin is in the line between the locking magnet 7 and the signal transmitter a pushbutton switch 36, which can also be actuated with a key or the like, is arranged in an inconspicuous place, which interrupts the circuit to the magnet and thus deactivates the lock.

This push button switch can now be designed in such a way that it only allows the car door to be opened once and the lock is immediately effective again when the car door falls into the lock again the block always remains in effect and can only be permanently overridden by rectifying the fault will.

The individual structural parts shown in the drawing are designated with the following numbers. The display plate for "free" or "occupied" and the corresponding operating lever bear the numbers 16 and 17. The so-called lock cover is denoted by 18 and the display of a malfunction that also done automatically by the transmitter, consists of the lamp 21, the display disc 20 and a clamping bracket 22 together.
