CS205754B1 - Device for bolting the tilting cabin of the driver - Google Patents

Description

The invention relates to a device for closing a tilting cab of a driver. The field of application of the invention is in the field of motor vehicles. The objects on which it can be used are folding driver's cabs, especially those of commercial vehicles.

There are already known devices for closing a tilting cab of a driver, which are formed on the principle of so-called hook latches and in which the latch bolt is closed by a hook.

By repairing the additional elements for controlling the movement of the hook, it is possible to meet the requirements set by the ECE conditions, as well as manual unlocking and automatic locking.

Such a solution is described, for example, in GDR patent No. 121754, according to which a special movable actuating plate is provided, which is articulated by means of a pin housed in the body in the recess of the actuating plate in the longitudinal bore.

The main disadvantage of this control plate is that it can become jammed due to the guide on the pin in the recess in the form of an elongated hole, which considerably limits the operation of the picking device and can lead to complete locking of the closure. Although this danger can be reduced by arranging two control plates on either side of the knitting rod which are connected to each other, this entails a considerable cost increase and, in particular, an increase in the stopping space for the device (which is in the driver's cab) very rarely available.

The purpose of the invention is to provide a locking device which does not have the disadvantages of the device described in said patent, which provides a functionally reliable locking of the driver's tilting cabins, which cannot be jammed by jamming the controls and occupies only a minimal stopping space.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hook-and-loop shut-off device for the driver's folding cab which complies with the EOE provisions regarding manual unlocking and automatic locking, and whose dimensions are only such as to require very little stopping space.

This object is achieved by the invention which consists in lying on the rear side of the driver ' s tilting cab about a pivotable metal hook which is known perpendicularly to which a spring force acts. The outer edge of the sheet metal hook is formed as a sliding edge having a known degree of interruption. Parallel to the plane of the metal hook are the connecting angle and the control (a lever that is rotatable about a common pin in both directions of rotation. A protruding sliding pin and a control lever support are arranged in the plate hook plane. for snap bolt.

At least one spring is applied to the connecting bracket and the control lever, the opposite end of which is connected to the metal hook. In the area of the control lever support, the control lever rests on the connecting rectangle.

An opening to which the control device is connected is arranged in the draw lever, which is arranged opposite the hook shape of the metal hook.

To unlock the locking device for raising the driver's cab, the metal hook is rotated by pulling the pulling lever from the rest position until the sliding pin of the connecting bracket, which moves along the sliding edge of the metal hook, engages in a step break of the sliding edge. This locks the hitch. Upon lifting, the metal hook moves upward, with the latch pin sliding along the leading edge of the actuating lever and rotating it from its position to the extent that the actuating lever latches back to its starting position by the force of the spring.

When retracting the driver's cab, the latch pin first engages the leading edge of the control lever. Through the support of the control lever, the rotating pilot rotates the connecting angle from the position in which it locks the metal hook, thereby releasing the sliding pin of the connecting angle to release the metal hook. Under the action of the spring force, the metal plate locks back. and the latch pin is closed by the metal hook.

The described solution permits a one-sided arrangement of the actuators, since the guide is carried out precisely by means of a common pin of the actuating lever and the connecting angle, so that some parts cannot become jammed. This makes it possible to make the locking device flatter than before and the conditions for its incorporation into the structure are considerably more favorable!

In addition, this solution fully satisfies all the requirements of 1ECE, which are also applicable to folding driver's cabs.

The invention is explained in more detail below in an exemplary embodiment in conjunction with the drawing.

The invention shows a locking device according to the invention with a metal hook and a pawl in a side view.

On the rear wall of the driver ' s tilting cab 1 there is a pivot hook 3 which is pivotable on the pin 1 and on which the spring 2 acts. This metal hook 3 embraces a latch pin 4 arranged fixed on the chassis frame II. In the upper part of the sheet metal hook 3 there is provided a pulling lever 5 with which it engages the control rod.

In parallel to the plane of the metal hook 3, there is arranged a connecting angle 7 and an operating lever 8, which are mounted rotatably around a common connecting pin 6 on the driver's cab. Connection angle 7 and control: lever 8 can rotate in both directions.

A sliding pin 9 is provided on the connecting bracket 7, which protrudes into the plane of the metal hook 3 and abuts the sliding edge of the metal hook 3 and the support 10 of the actuating lever 8. On the actuating lever 8 is a leading edge 11 for the pawl. a spring 12 is fastened to the connecting angle 7, the other end of which is connected to the sheet metal hook 3. A spring 13 is mounted on the control lever 8, the other end of which is also connected to the sheet metal hook 3.

If the driver's cab 1 is to be folded upwards, the metal hook 3 is first rotated by acting on the pulling lever 5 from its initial position to such an extent that the sliding pin 9 of the connecting bracket 7, which moves along the sliding edge of the metal hook 3, It locks into the sliding edge 14. This keeps the metal hook 3 in the new position.

When lifting the cab I of the driver, the metal hook is used

3.Moving upwards. The latch pin 4 moves along the leading edge 11 of the actuating lever 8 and rotates it to the extent that the actuating lever 8, after passing through the latch pin 4, engages with its spring force 13 its back (initial position).

When the driver's cab 1 is lowered back into the driving position, the pawl 4 runs onto the leading edge 110 of the control lever 8. By engaging the control lever 8 on the support 10 of the control lever 8, the control lever 8 rotates the connecting bracket 7 from that position. This will release the sliding bolt 9 of the connecting bracket 7, the metal hook 3. By applying the force of the spring 2, the metal hook 3 latches back and embraces the latch bolt 4 with its inner side of the hook.

Thus, the driver's cab I is closed on the chassis frame II of the vehicle.
