Abstract

Use: when developing locks for apartments, safes, etc. SUMMARY OF THE INVENTION: A magnetic lock comprising a housing, a clip, a plate consisting of disks, rods, a latch and a key with magnets. The castle operates as follows. In the Closed position, the rods are in the underground slots of the housing and, when attempting to rotate, the clips work to cut. After installing the key, the magnets install the rods in the annular groove of the housing and they do not impede the rotation of the heck. The lock is moved to the Closed position when the key is removed. 1 s.p. f-ly, 7 MP .: -, -. :. .. . - .. ..l. ; . . ...

Description

The invention relates to household appliances, and more particularly to a device for locks using permanent magnets, and can be used in door locking devices.

The purpose of the invention is to increase operational reliability.

In FIG. 1 shows a general view of a magnetic lock in the Closed position; in FIG. 2 - the same in the Open position; in FIG. 3 and 4 are a cross-sectional view of the lock in the Closed and Open positions, respectively; in FIG. 5 shows the principle of operation of the washer to provide control of the locking rods; in FIG. Figures 6 and 7 are exemplary embodiments of means for supporting the installation of rods.

The magnetic lock comprises a housing 1, with means for providing key rotation formed on the inner surface of the annular groove 2 and a longitudinal groove 3; grooves 7 and the hub 8, a rotary holder 9, with longitudinal blind holes 10, a washer 11 mounted on the holder 9, q holes 12, a plate formed by disks 13 and 14 of a means for providing. th, locking rods 15. located in holes JO and 12, grooves 7, radial grooves 5 and pivotally mounted between discs 13 and 14: The magnetic lock also contains a key 16 with sockets 17, carrying orientation magnets 18 installed in the sockets 17 and provided protrusion 19.

The magnetic lock can be equipped with a clutch 20 with grooves 21, a spring-loaded spring 22 mounted on the hub 8, on which the protrusions 23. are placed in the grooves 21.

The magnetic lock may have a movable housing 24 mounted on the housing 1 and secured against longitudinal movement, for example, by a locking ring 25.

The magnetic lock operates as follows. In the Closed position (see Fig. 1), the locking rods 15 under the influence of gravity are in radial

grooves 5, in the General case, not falling into the annular groove 4 (see Fig. 3).

To bring the lock into the Open position, it is necessary and sufficient to install the key 16. The protrusion 19 in this case passes through the groove 3 into the annular groove 2 (see Fig. 2). Then the orienting magnets 18 establish the locking rods 15 so that they are located in the annular groove 4 (see Figs. 4 and 5). Thus, the lock is set to the Open position, since nothing prevents the key 16 through the clip 9 to rotate the latch 6.

The lock is put into the Closed position when the key is released 16..

In this case, the orienting magnets 18 cease to control the locking rods 15, and they become disoriented by the force of gravity, i.e., they exit from the annular groove 4 and enter the grooves 5.

Setting the locking rods 15 to the Zero position when their hinge position is above the intersection of the grooves 4 and 5 is provided with means for providing key rotation that allows the key 16 to be released in only one position when the protrusion 19 is in the longitudinal groove 3.

When trying to rotate the clip 9 without first orienting the locking rods 15, the latter also fail in the grooves 7 and grooves 5 and, cutting work, prevent the latch 6 from rotating.

In case of an attempt to rotate the movable housing 24 around the axis of the lock, it rotates around the axis without transmitting torque to the locking part;

An exemplary embodiment 4 of the means for arranging the installation of the rods is shown in FIG. 6. Installation takes place, for example, as follows. After installing the plate 13, using snap-in, for example, 26, the locking rods 15 are pre-installed, and then the plate 14 is fixed.

In FIG. 7 depicts another principle of operation of the rod mounting means.

The principle of increasing reliability by making locking rods with a square cross section is illustrated in Fig. 3, where in place H is shown a rod preventing rotation of the latch, and a dashed line is a rod if it had a circle in cross section. It is easy to see that in the second case, the locking rod would not impede the rotation of the latch, since the rod will fall into the annular groove 4, leaving the longitudinal groove 5.

Providing the lock with a 1Q spring-loaded clutch allows it to be mounted on.

doors of different thicknesses, The rotation is transmitted through the protrusions 23 of the hub 8, to the clutch 20 through the grooves 21. If the thickness of the door is less than the distance from the cage to the end of the clutch, then when installing the shut-off

parts of the clutch will move inside the housing 1, compressing the spring 23 .:.

The lock is user-friendly due to the fact that after removing the key, the lock is in the closed position.
