Description

Door latch for doors vehicles.

Object of the invention

Door latch for doors vehicles.

Field of the Invention

The present invention relates to a latch door, which prevents blocking of vehicle doors from its interior and can be mounted later on the doors.

Background of the invention

In the state of the art, in the industry automobile, the mechanisms of the locking latches of the vehicle doors are being manufactured in such a way that they block the doors of the vehicle when turned in one direction and open the vehicle doors when turned in the opposite direction.

In vehicles that are provided with this kind of door latches, especially in vehicles commercials used in school transportation services of children, in case the passengers had to be evacuated due to dangerous situations, the panic that can originate in these conditions and the young age of the passengers can lead to move the door latch in the opposite direction to the proper one and It can cause material losses and deaths.

As a result of the reasons stated previously, especially in vehicles used to passenger transport, and in order not to endanger the passenger safety in case of emergency due to lack of time to react, a door latch is necessary that prevents the blocking of the doors from inside the vehicle.

The door latch (Figure 2), which is the object of the present invention, causes the rotation of the handle (1) in one direction (in the direction of opening the door) by moving the spring support (5) inside (Figure 3) between the lock shaft gears (11) and when the lock is drives in the opposite direction, the blocking trees (6, 7) remain crazy and do not block the vehicle door. In this way, in Dangerous circumstances that require the evacuation of vehicle passengers, the vehicle door latch does not it will allow the blocking of the doors from the inside and avoid wasted time caused by the error blocking of the door.

Detailed description

As can be seen in Figure 2, the latch of Door object of the present invention is composed of lock trees consisting of five independent parts linked together (6, 7, 9, 10, 11), a door latch (12), a control support element (8) movement transmitter that receive the trees (6, 7, 9, 10, 11) from the latch (12) and locking safety springs (15) at both ends of the door latch.

The detailed view of the door latch (12) is shown in Figure 3. As can be understood from the Figure 3, the body of the door latch is composed of a handle (1), a spring (4), an inner ring (2), a support spring (5) and a pin (3). The ring spring (4) in the inside the door latch (Figure 2) is located in the handle (1) and at one point the two ends of the spring are open, one of these open ends bent towards inside (Figure 4). The inner ring (2), which is shaped cylindrical, it is arranged precisely inside the spring (4). On this part (2) is a support of spring (5) presenting a straight projection that goes from a point of the outer surface and passes along the entire surface (Figure 5). The pin (3), which is a cylindrical rod, fixes the position of the spring support (5) Attention has been paid special at the distance of the open hole in the support spring (5) in order to place the pin (3) in position appropriate to allow the movement of the spring support (5) in a sense.

The door latch (12) is located in the control support element (8) of the locking shaft (Figure 2) by means of an adhesive tape. In this way, the support of spring (5) is housed in the locking shaft mechanism (11)  located in the control support element (8) and as consequence performs the movement of the handle only in one sense. As mentioned above, the distance of the open hole to accommodate the pin (3) used with in order to fix the spring support (5), it provides the movement of the spring support (5) only in one direction.

With this connection, when the lock is operates in the opening direction, the handle (1) rotates, and as consequently the spring support (5) acts in the same direction and activates the locking shaft (11) that acts on the mechanism of the spring support (5). By activating the tree lock (11), the door latch is released and the door is opens. Similarly, when the lock is turned in the direction opposite, because the position in which the support has been fixed of the spring (5), the handle (1) goes crazy and does not make any movement. Taking into account that the handle (1) does not move, neither does any door tree move, which could perform the door lock and door latch to which it is attached the handle

As discussed in detail above, the  Door latch object of the present invention prevents the door lock from the inside and can be mounted with after the doors. In this way, in a situation of danger that may occur in the vehicle, the loss of time that may originate as a result of blocking the door, which would prevent the evacuation of passengers. In a emergency situation in the vehicle, where the panic and the ignorance of the elderly or children did not possible the activation of the door lock in the direction correct, this invention is extremely useful. So especially in commercial vehicles that carry passengers, the presence of a blocking system that prevents blockage of doors from the inside is of great importance for the passenger safety

Claims (1)

1. Door latch (12) used especially in public transport vehicles, which is subject by means of an adhesive tape (14) on the control support (8) of the Locking mechanism and eliminates the risk of door lock of the vehicle from the inside, which comprises:

-
