DOOR LOCK, IN PARTICULAR PUR MOTOR VEHICLES

The invention relates to door locks. Such locks contain a locking latch that can be rotated between a release position and a locking position, a locking bolt and a mechanism for Rotation of the latch from the locking position to the release position. When the latch is turned to the locking position and the two Parts are joined together by the interlocking of the striker and the latch, the resulting force is between the contact surfaces of the locking bolt and the locking latch through the pivot point of the locking latch through or to the side of this pivot point. This has the consequence that the latch still further into its blocking position is rotated.

The force required to operate the mechanism, namely that required to rotate the latch into the release position, is sometimes unusually high. This is due to the fact that the latch is hindered in its rotation by the locking bolt. According to the present invention, the locking bolt is also rotatably arranged between a blocking position and a release position. With an opening force at the T ¹ Ur in the locking device, the resulting force action between the contact surfaces of the locking bolt and the locking latch passes through the axis of rotation of the locking bolt or by close to this axis. As a result, it is turned further into its locked position. The axis of rotation

of the Sohlioßklobens is located between the contact surfaces and the Fulcrum of the closing trap that when the mechanism for rotation of the Gel iließfalle is actuated in the release position, the closing latch the Closing pin rotates in such a way that as a result of the arrangement of the axis of rotation the locking latch the contact surface of the locking bolt on the contact surface the latch slides by. In this way the possibility becomes an obstruction of the latch by the locking bolt when rotating into the release position is greatly reduced. The latch preferably has an approach that in the locked position against the contact surface the locking block ^; opposite side or almost adjacent and when the latch is turned to the release position, against strikes the locking bolt and rotates it into its release position. the Investment areas are preferably flat.

Locks according to the present invention are particularly suitable for installation in Suitable for motor vehicles. The latch is preferred here attached to the door and the striker attached to the door jamb. Hereinafter the invention is explained with reference to the drawings. Show it:· '

ticfun. '¹; 5 ondot in TUchtunf-; Door stop on a floor 7 ^a · Mechanism for rotating the latch 1 is mounted on the side of the Dasio surface in the recess 5 facing the door. The latch 1 is provided with a bolt that protrudes through the basic surface.

The lock block 3 is mounted on a plate, which in a (not shown here) door post of a motor vehicle can be attached. There is also an upper guide body on the plate 7 and a lower guide body 9 attached.

The closure 1 is spring-loaded in a clockwise direction and with a guide part 11, a shoulder 13 and a flat contact surface 15 provide. The closing block has a flat contact surface 17. When the door is closed, the recess 5 slides over the Rihrungskörpor 7 and 9 and is in a perpendicular opposite the door Position taken. If dan guide part 11 of the safety catch 1 against the protruding corner 18 of the upper guide body 7 abuts, rotates the latch 1 turns counterclockwise and slides past the protruding corner 18. As the guide part slides by, 11 on the protruding edge 18, the latch is brought into the position shown in FIG. 4 as a result of its spring preload. this is the position of security. In this position the door can be opened by turning the latch 1 counter to the UiirKcigersinn. When the guide part 11 at the protruding Edge ItS vorboigleitct, a surface 19 on the latch 1 is opposite a surface 21 on dom locking block 3. This turns it clockwise rotated against a stop (not shown here) and thus Iri brought a blocking tunnel.

Thus, no opening force on the door can cause the latch 1 to rotate into the release position. When the latch 1 and the locking block 3 assume this position, the axis of rotation 25 is closer to the support surfaces 15 and 17 than the pivot point 2j5, and the contact surface of the locking block 5 rests against the contact surface 15.

When the mechanism (not shown here) is operated with the purpose of rotating the locking arrangement counterclockwise, the contact surface 17 and the contact surface 15 of the latch 1 rest against one another. The locking block J> is therefore rotated counterclockwise. Since there is a smaller distance between the contact surface 17 of the locking block and the point of rotation 23 than between the contact surface 15 and the point of rotation 23 ' , the contact surface 17 of the locking block moves a little away from the contact surface 15. This facilitates the rotation of the latch 1 into the release position. If, as in previously known designs, the locking pin j5 is firmly attached (i.e. not rotatable), the contact surface 15 of the latch 1 hooks on the protruding corner between the contact surface 17 and the surface 21 of the locking pin J5. As a result, the force required to rotate the closing latch 1 is increased.

In Fig. 1 the lock is shown in the locked position and in Pig. 2 in the position in which the latch is turned a little counter-clockwise. In Fig. J) it is drawn in the position in which the contact surface 15 has just slid past the protruding corner between the contact surfaces 17 and 21 of the locking bolt J> .

that the locking bolt 3 is designed differently. In this version is the locking bolt by the contact surface 15 of the latch 1 force acting on locking block J5 is rotated into its release position. .
