1 shows a schematic diagram of a door lock with a locking insert 10 having a keyhole 11 in which a foreign substance, in this example a matchstick 12, is inserted into the keyhole 11. It is an object of the present invention to prevent foreign material from being inserted into the keyhole in such a vandal way as to prevent the lock from being used by the mother *

They can be removed from the keyhole without dismantling the lock.

2A-5. The door locks shown in Figs. 2A-2C., 3. and Figs. 5 and 5 show a one-sided lock with a lock cylinder 22 on one side and a handle 24 on the other. Figures 4A-4C show a double-sided lock.

The lock cylinder 22 may be a known lock cylinder having a keyhole 26 with code locking pins 28 which can be used in both a single-sided lock and a double-sided lock. The locking insert has at its inner end a locking tongue body 44 which is pivotally disposed in the insert housing and is formed by an axial bearing pin 36 formed by a turn key 30 engaging with a key 60 and a pin 38 inserted into the shaped opening 66 A compression spring 34 is provided between the pivoting member and the carrier pin 36, and a further spring 42 supported by a ring 40 on the stud 38 is provided. The axial movement of the pivoting member 30 in the lock cylinder 22 is delimited by a stop bolt 32 transverse to the keyhole 26. (Figures 2A and 3)

The pivoting member 30 is held in the rest position 34 by the spring 34 away from the stop pin 32, in which position the projection 38 does not engage the tongue body 44. (Figure 2A). 2A. The rest position shown in FIG. 6b is when the key 60 is not inserted into the keyway 26 or is not fully inserted. In Fig. 2, matchstick 46 inserted into keyhole 26 • · · * ·

-βίε is indicated.

2A. As illustrated in FIG. 4a, the locking cylinder 22 is secured axially in the housing 20 by the retaining ring 48 and the handle 24 by the retaining ring 50. The nose 54 of the handle 24 engages the tongue body 44 with the tongue body shaped opening 66 and is thus operable.

The handle 24 has a hollow handle portion 52 sealed by a handle handle 68 to extend the inner end of the keyhole 26 so that foreign material entering the keyhole 26 can be moved to the hollow handle portion 52 (Fig. 2B).

When the key 60 is fully pushed into the keyway 26 (Figures 2B and 3), the front end of the key 60 pushes the pivoting member 0 0 axially against the compression spring 34 to the stop pin 32. Thus, the pin projection 38 is pushed through the spring support ring 40 and pressed against the spring 42 to engage the tongue opening 66 of the tongue body 44, allowing the tongue body 44 to be rotated by turning the key 60 and thereby the lock cylinder 22. During rotation of the tongue body 44, it actuates the door lock into which the locking insert is integrated.

As the key 60 is pushed into the keyway 26, the foreign body enters the keyway, in which case the match wire 46 is pushed out of the keyway 26 along with the stop pin 32 and moved into the hollow handle 52 of the handle 24. It is noted that the hollow compartment 52, which is formed as a hollow handle 52, can be emptied by removing the handle 68 or by removing the locking ring 50 of the handle.

2C. In the embodiment of FIG.

The hen 9 is provided with a channel 70 with an opening 72 opening into the environment through which a foreign body or material ejected from the keyhole can be removed without removing the handle.

4A, 4B. 1 to 4 there is a first lock cylinder 122 on one side and a second lock cylinder 123 on the other side. The lock cylinders 122,123 may be of the same known design. Interlocking pins 128,129 corresponding to the same key code are provided in the key holes 126,127 of the lock cylinders 122,123.

Between the two locking cylinders 122,123 there are 144 tongues and tongue-connected pivoting means 160, the axial movement of the pivoting means 130,131 in the locking cylinder 122,123 is limited by the pivoting position 132,133, which is fixed perpendicular to the key opening 126,123; from the stopcock.

The compression spring 134,135 is disposed between the pivoting element 130,131 and a carrier pin 136,137, the pin 138,139 extending axially to the tongue 144 and extending through the ring 140,141 which rests on the tongue 144. The springs 142,143, when at rest, keep the studs 138,139 disconnected from the tongue body 144. This condition is shown in FIG. illustrated in which one of the matched threads 146 inserted into the keyhole 126 is shown.

• ·

The lock cylinder 122,123 is secured in the housing 20 by an axial displacement ring 148,149.

4B. The key 160 is fully depicted in the keyhole 126. The leading edge of the key 160 pushed the pivoting element 130 axially up to the stop pin 132. This movement of the pivoting member 130, through the compression spring 134, pushes the stud 138 of the carrier pin 136 through the ring 140 while the spring 142 is compressed. The pivot pin 138 extending through the ring 140 engages the shaped opening 166 of the tongue body 144 so that the tongue body 144 is carried with it when the key is turned. The swiveling 144 tongue bodies move the door lock tongue.

The same process occurs when the key is not inserted in the keyhole 126 but in the other side keyhole 127 and rotated in the lock. In this case, the projection 139 of the other side structure engages with the shaped opening 160 of the tongue 144.

4B. It is also apparent from Figures 1 to 4 that when the key 160 is inserted, the matchstick 146 is pushed out of the keyhole 126 by pushing it against the stop pin 132 into the other side keyhole 127.

4C. Fig. 4A shows a preferred way of removing the matchstick from both lock sides. The matchstick 146 is removed from the lock by means of a cleaning tool 170 which has a narrow and long blade 172 fixed in the handle which can be pushed through both keyholes 126,127. The slightly elastic blade 172 is at least as good as · · · ♦ · ·

- 11 122,123 lock cylinders are twice as long and terminate in a flat, perpendicular surface. The cleaning tool 170 is inserted into one of the keyholes 126, the blade end face is supported by the matchstick 146 or other inserted object and pushed through the keyhole on the opposite side, thus completely eliminating the blocking action of the lock. Of course, the tool can be inserted into the lock from the other side, and both sides can be cleaned equally.

6, 7A. 7B and 7B. Figures 1 to 5 illustrate a padlock. The padlock body 210 is made of a relatively soft material, such as soft iron, and is provided with a steel sheet jacket 212 and a vehicle shielding fastener 228 for increased security. The sheet metal casing 212 is preferably made of heat-treated steel.

The lock body 210 includes a lock cylinder 214 which may be any suitable known lock cylinder. The key hole 216 of the lock cylinder 214 is an opening through the lock cylinder which extends from the outer cylinder end 218 of the lock cylinder to the inner cylinder end 220. The locking cylinder 214 moves first and second locking plates 222,224 (Figs. 8A, 8B) for securing the two ends of the yoke 226 in the lock body 210.

The optional fastener 228 is fastened to the steel plate jacket 212 by screws 230. The outer cylinder end 218 of the lock cylinder 214 is covered by a sliding door 232 which is disposed inside the steel plate jacket 212 behind the outer key hole 234 formed therein.

However, the door panel 232 should not prevent anyone from deliberately blocking the material 236 into the keyhole of the lock. In order to remove the blocking material, the locking body 210 of the exemplary padlock has a collector 238 behind the inner cylinder end 220, into which the key 240 inserted into the keyway 216 may insert the blocking material 336 to release the keyway 216. In a preferred embodiment, the container 238 is open to the environment through an opening 242 through which the foreign matter or object can be removed directly. 7A, 7B. In the example shown in Figures 1 to 4, the opening 242 is threaded and closed by one of the screws 230. Alternatively, a collector space 238 may be dispensed with and an open or open opening permanently open to the outside is disposed opposite the key opening (Fig. 6).

8A. Fig. 8B shows the lock in the closed position; Fig. 6A shows the locking plates 222,224 in the open position. It is also apparent from the figures that the locking plates 222,224 are formed with a cut-out which leaves an open opening in front of the key opening through which foreign material can be pushed out of the key opening.
