WITH

This invention relates to locking devices with electromagnets.

An electromagnetic lock is known that contains an electromagnet installed in housings, a rod with a spring, a microswitch, a spring-loaded bolt, an internal and external control knob, and a communication mechanism between the button of the external handle and the microswitch.

The well-known lock requires turning the handles when opening the doors, the structure of the lock is complicated. The presence of an external control knob is available for malicious damage to the lock.

The purpose of the invention is to increase the convenience of operation, simplify the design of the lock, protect the lock from damage.

The goal is achieved by the fact that an electromagnetic lock contains an electromagnet with

a rod, a microswitch, a double-arm lever, a spring-loaded bolt, a knob, on whose axis there is a catch with a finger, which, through a communication mechanism, interacts with the bolt, the inner and outer handles. In the proposed lock there are no movable lock handles, the kinematics are simplified,

Figure 1 shows the castle, a general view; figure 2 - section aa in figure 1; on fig.Z - view B in figure 1; FIG. 4 is a view B of FIG. 3; figure 5 is a view of G in figure 4.

An electromagnetic lock consists of a door lining 1 in which an electromagnet 2 is installed, a microswitch 3, a bolt 4 with a spring, a rod 6, a double-arm lever 7, a knob 8, on its axis a clamp 9 with a finger 10 and spring-loaded spring 11, an emphasis 12. Mechanism closed by a lid 13.

The inner handle consists of a housing 14, in which a button 15 with a spring 16 is installed, a leash 17, a rod 18, a latch 19 with a spring 20.

The handle 21 is installed on the outside of the door.

Electromagnetic lock works as follows.

Outside, the lock is opened by inserting a key into an encoder (not shown). At the same time, the electromagnet is turned on and moves the rod 6, which through the double-arm lever 7 draws in Rmgel 4 and the lock opens. From the inside, the lock is opened by pressing the button 15, which, through the lead 17 and the rod 18, retracts the latch 19. When the door is closed, the latch 19 turns on the rod 18, passes the bolt 4 and the lock closes. In an emergency (no power), the lock is opened with a key for an encoder that has a tide. The key is inserted into the groove of the driver 8, and by pressing it in the axial direction the retainer 9, the stop 12, engages the two-arm lever 7 (Fig. 4). By turning the knob 8, the locking pin with its finger 10 through the communication mechanism is engaged in the bolt 4, and the lock is opened.

So that the lock is not opened with a third-party object, in the presence of electricity, the lock is locked, which is performed as follows.

When the knob 8 is pressed axially, the clamp 9 moves and becomes in the path of movement of the rod 6. At the same time, the microswitch 3 switches and the electromagnet turns on, which begins to move the rod 6. The latter locks the cranking of the knob 8 with its collar 6 with a latch 9. At the same time, further movement of the rod 6 is stopped (Fig. 5).

In the absence of electricity, the stem 6 with the collar is in the designated position, and when turning the knob 8, the clamp 9 passes by the collar and zamrk

is blocked.

The use of the invention allows, with minimal dimensions and simplicity of the I design, to ensure reliable locking regardless of the thickness of the door leaflets.

and opening directions.
