3- The present invention is a lock system according to Claim 1, characterized by comprising a hatch lock bolt (4) that stretches inside housings located on the body (1) allowing the lock bolt (4) to be fitted into its place even though the lock bolt housing (2) is in closed position.

Description:
SELF-ADJUSTING LOCKING SYSTEM

The present invention relates to a self-adjusting locking system usable in all types of white appliances such as dishwashers and washing machines that utilize hatch locking mechanisms which allows the user to shut the machine hatch even though the lock bolt's housing is closed. Technical Field of the Invention

The present invention relates to locking systems used in all types of white appliances. Problems That the Invention Seeks to Solve

Due to an unknown reason, following the switching of lock bolts in locking mechanisms to a closed position while the hatch is open, hatches of dishwashers or suchlike devices cannot be closed and when the hatch is forced to shut by the end user housing of the lock bolt breaks. In both of these cases end users end up calling technical service personnel.

State of the Art

In all of the manufactured white appliances, locking mechanisms are mounted on the hatch. The hatch gets locked once the lock bolt mounted on the machine's hatch slips into the lock bolt housing located on the lock's body and teeth on the lock bolt housing goes into the gap located on the lock bolt when the machine's hatch is closed. After the switch locking operation on the lock's body is carried out, the machine receives a signal and the operation · commences. While the hatch is open, lock bolt housing located on the hatch could switch into a closed position due to an unknown reason. Because of this particular unknown reason, when the end user tries to shut the hatch lock bolt does not go into the lock bolt's housing.

The present invention, against locking issues seen in locking systems used in white appliances and hatch shutting problems occurring due to an unknown reason when the lock bolt housing located on the hatch's locking mechanism relates to a self-adjusting locking system that allows hatches to be shut no matter what position the lock bolt is in.

Gliding channel located on the locking mechanism body on which the lock bolt housing is mounted, pushes the teeth of the lock bolt housing which is in a closed position while the lock bolt is going into the said housing once the lock bolt housing is closed.

Brief Description of the Invention

l The present invention relates to a self-adjusting locking system that converts a horizontal motion into a vertical motion in the lock bolt housing (2) inside the gliding channel located on the lock body (1) by using the available spring (3) of the lock group without rotating the lock bolt housing (2) on the lock body (1) which occurs during the collision action of the lock bolt (4) when hatch of the white appliance is closed.

Disclosure of the Invention Subject matter lock system is characterized by comprising lock body (1), gliding channels (6) located on the body, lock bolt housing (2), lock bolt (4), hatch safety switch (5) and spring

(3) .

Subject matter invention relates to a self-adjusting locking system that converts a horizontal motion into a vertical motion in the lock bolt housing (2) inside the gliding channel located on the lock body (1) by using the available spring (3) of the lock group without rotating the lock bolt housing (2) on the lock body (1) which occurs during the collision action of the lock bolt

(4) when hatch of the white appliance is closed.

The present invention is a lock system that forms a group with hatch safety switch (5), lock bolt housing (2) and spring positioned on the lock body (1), When the hatch is opened the lock bolt (4) that locks the hatch, lock bolt housing (2) rotates on the housings located on the channeled lock body (1) and disengages from the lock bolt (4). In case the hatch is wanted to be shut in available systems when the lock bolt housing (2) switches to a closed position by an extraneous force while the hatch is open, because the lock bolt (2) is shut, locking system prevents the hatch from being closed.

Figure 1 illustrates the exploded view of the self-adjusting lock system. Lock body (1) is located on the hatch and keeps lock bolt housing (2) and spring (3) mechanism atop and facilitates movement upon the gliding channels (6) located on the body (1 ).

Lock bolt housing (2) holds the teeth that goes into the lock bolt's (4) gap and mounted on the lock bolt's body (1). When the lock bolt (4) is forced to be shut lock bolt housing (2) allows the lock bolt (4) to be seated by pushing it downwards through the gliding channels (6) located on the body when the lock bolt housing is in closed position.

Spring (3) is positioned between the lock bolt housing (2) and lock bolt body (1). Spring (3) holds the lock bolt housing (2) on the lock body (1) under a certain amount of pressure. By this means it prevents the lock bolt housing (3) to close itself while the lock is open.

Lock bolt (4) is the part that is mounted on the machine's main frame and that allows the hatch to be locked. The teeth located on the lock bolt housing (2) goes into the gap at the end of the lock bolt (4) which allows the performing of the locking action.

Hatch safety switch (5) is mounted on the lock body (1). Once the hatch is closed it sends a signal to the machine which then initiates the operation of the system. When the hatch is open it deactivates the system automatically.

In Figure 2 top view of the self-adjusting lock system is provided. It demonstrates the particular position when the lock bolt (4) goes into the lock bolt housing (2).

Figure 3 shows the frontal perspective of the subject matter self-adjusting lock system. In this Figure position of the gliding channel (6) can be observed. Gliding channel (6) is located on the lock body (1) and below the lock bolt housing (2).

In Figure 4 a detailed view of the gliding channel (6) is provided. Gliding channel (6) located on the lock body (1) assumes an assistive role in locking of the lock bolt (4) by sliding downwards during the action of closing the hatch while the lock bolt housing (2) is closed. In the subject matter self-adjusting lock system, lock bolt housing (2) upon the gliding channels (6) located on the body moves the lock bolt (4) by stretching the lock bolt housing (2) allowing the lock bolt (4) to be fitted into the gap then it returns to its former position completing the locking action by means of the spring (3).

In the subject matter invention lock bolt housing (2) moves in gliding channels (6) located on the body (1) by means of the spring (3). If the lock bolt housing (2) switched to closed position even if the hatch is open, lock bolt (4) moves the lock bolt housing (2) upon the lock body (1) allowing the lock bolt (4) to be fitted into its hole and completes the operation of the lock system by restoring the lock bolt housing (2) back to its former position.

On account of the present invention, lock bolt (4) stretches inside housings located on the lock body (1) even if the lock bolt housing (2) is closed allowing the lock bolt (4) to be fitted to the hatch.
