Description

Technical area

This technical solution relates to a safety device for cars, including a latch controlled by a cylinder lock.

The current level of technology

The safety device for vehicles of this type can be classified, depending on the design of the cylinder lock, into a safety device with a rotating cylinder lock (utility model RF 10380, publ. July 16, 1999; CZ 6786, publ. 11/10/1997) and a safety device with a cylinder lock moving in the axial direction (utility model CZ 48, publ. 24.12.1993).

The safety device with a rotating cylinder lock (utility model CZ 6786, publ. 10.11.1997), taken as a prototype, can be adjusted depending on current conditions. But such devices are not applicable in cases where, for any reason, it is impossible or impossible to attach a curved connecting piece between the latch and the rotating cylinder lock to the radial cylinder lock in the radial direction. Typically, in these cases, it was necessary to place the cylinder lock in such a way that it was difficult to access for maintenance personnel, or additional operations were required, for example, moving the saddle, etc. In such cases, safety devices with a cylinder lock moving in the axial direction are used. Their present design has a disadvantage due to the fact that the cylinder lock in the unlocked position protrudes above the surface.

Since the safety device is usually located in such a way that it can be seen outside the car, it is noticeable at first glance where the car is open.

The basis of the technical solution

The purpose of the technical solution is to create a safety device for cars, which would allow, while maintaining the simplicity of design, to use

connecting part of a rotating cylinder lock with axial mounting.

To a large extent this can be achieved in a safety device for cars, including a rotary cylinder lock connected to a latch by means of a connecting part according to this technical solution, which is mainly based on the fact that inside the casing the cylinder lock is connected to a cam, to which through the lever is attached to the spring, and the lever is interconnected with the latch through the connecting part.

A favorable condition is if the spring is put on the connecting part, and one of its ends abuts against the lever, and the other end abuts against the base of the expanded part of the hole in the channel of the connecting part.

Graphic materials

The technical solution is explained in detail using schematic drawings. 1 shows a safety device for cars in an unlocked position. Figure 2 shows the safety device for cars in the locked position.

Sample Description

As shown in figures 1 and 2, the safety device for cars includes a cylinder lock 3, located in the casing 1, which is designed to protect against violent breaking. The rotating part of the cylinder lock 3 inside the casing 1 is connected to the cam 4.

On the side surface of the cam 4, the casing 1 is connected to the channel 2, in which the connecting part 8 is placed, for example, a Bowden cable connected to the end of the channel 2 with a latch 6, and on the side surface of the cam 4 there is a lever 5. In engagement with the cam 4, the lever 5 is held by a spring 7, which, in a favorable case, is worn on the connecting part 8, and one of its ends abuts against the lever 5, and the other end abuts against the base 9 of the expanded part of the hole 10 in the channel 2.

The safety device is mounted in the car using latches 11, the design and position of which on the skin 1 depends on the type of car, and therefore they are not described in detail.

The safety device for cars in the unlocked position is shown in figure 1, which shows the relative position of the cam 4 and the lever 5, in which the latch 6 is fixed using a spring 7 inserted into the channel 2. Locking is carried out by turning the cylinder lock 3 and aligning the connected cam 4, which occurs due to rotation.

When the cam 4 is rotated, the lever 5 pushes the spring 7 into the channel 2, thus, the connecting part 8 pushes the latch 6 from the channel 2 to a position that is clearly visible in figure 2, where the locked safety device is shown. Unlock in the reverse order.

Industrial applicability

The technical solution is designed to protect vehicles, mainly for those equipped with an automatic transmission.
