Lid closure, in particular for motor vehicles

The innovation "concerns a lid lock, in which within» an orund body a push button for actuating a spring-loaded locking hook a ^: ial slidably arranged is,

In a known cover lock of the type mentioned above, the push button is made of die-cast zinc, which has the disadvantage that this push button has to be surface-treated before chrome-plating by grinding or the like, so it has to be reworked. The spring, against which the push button is axially displaceable, is arranged in the base body of the cover closure. For this purpose, the base body and the push button must be processed accordingly. In the case of the known cover closure, a contact surface of larger diameter is formed on the outer cylinder surface of the push button and a contact surface of smaller diameter is formed on the inner cylinder surface of the bore of the base body. Furthermore, the seal, which seals the known cover lock with respect to the push button, is arranged in an annular groove which is screwed into the cylinder bore of the base body. So it is a separate work ⁴ step for the production of this ring groove required.

The innovation is based on the task of providing a lid |

To create the conclusion of the type mentioned at the beginning, which

Swsbsnd does not have disadvantages listed and "cheaper I

is to be established. This object is achieved in that the 1st

sheet metal push button connected to the hook j

is. j

Because the snap # S is made of sheet metal, which "Can be done, for example, by punching or deep-drawing, it is no longer necessary to post-process the surface instead, the chrome plating can be done immediately after punching and drawing.

The Deekel closure is advantageously designed in this way that the push button has a visible cup-shaped section protruding from the base body and is formed thereon te arms that connect to the ratchet.

This embodiment can be easily produced and guaranteed performs a good function of the lid closure.

Since the push button is made of sheet metal, it is still possible to roll an annular groove into the cup-shaped section from which is used to accommodate a sealing ring. In the arrangement of the sealing ring in the push button itself is omitted screwing an annular groove into the base body of the cover closure.

It is also advantageous to use the spring against which the push button is axially displaceable, not to be arranged in the basic bait, but to train and fasten in such a way that it has two legs, one of which is directly dsn The locking hook is applied and the other is supported on the housing is. When the spring is arranged and designed in such a way that it moves the locking hook into the Kichtung in the closed position presses, in which the force of gravity also acts on the locking hook, there is the additional advantage that in the event of failure The spring does not unlock because the locking hook is still in the closed position due to the force of gravity acting on it is held.

Further advantages and details of the innovation can be seen from the drawing, in which the innovation on the basis of an Au management example is illustrated.

It shows:

Lock;

Fig. 2 shows a section through the lid closure fax Fig. * I along the line AB.

The lid closure shown in Fig. 1 consists of a Locking hook 10 with the help of a shaft 2 in a GrundköruBr 4 is supported and can be actuated by a push button 9. The locking hook 1 is acted upon by a spring 7 which is around the Shaft 2 is wound. The connection between the push button 9 and the locking hook is made via a split pin 3-

The push button 9 has a cup-shaped, visible portion and two arms 14 and 15, which on the split pin 3 with the

In Pig. 2 are the two arms 14 and 15 of the push button 9 illustrated in the base body 4.

All technical details recognizable in the description and shown in the drawing are for the innovation significant.
