SU1168099A3 - Vehicle door lock - Google Patents

Abstract

A turning stop member is mounted on a support piece attached to the door of a vehicle, together with a closing bolt attached to the vehicle body, working in conjunction with this when the door is closed. The stop is inside a retainer on the support piece. There is one elastic stress member (6) inside the retainer (4), and another (8) attached to the body. With the door closed, the first acts with the closing bolt for elastic absorption of displacement forces between door and body, and the second acts with the outside face of the retainer to check vertical relative movements between them. Relative movements between door and vehicle body are more effectively prevented.

Description

This invention relates to a device for fixing transport door means.

The purpose of the invention is to improve the operational capabilities by eliminating the vertical displacement of the pin.

FIG. 1 shows the structure of a pin with a fixing plate; in fig. 2 shows a housing structure with a locking plate; FIG. 3 the relative position of the elements of the lock in the closed position.

The lock contains a stop element 1, which is fixed on the fixing plate 2 in its recess 3, a casing 4 with a window for entering the Igryr 5, inside which a stop is installed on the axis 6, a plate 7 with a recess 8. In the recess 3 of the plate 2 the direction 9 is fixed which houses a wedge-shaped support 10, a spring-loaded compression spring 11, which is located between the stop 10 and the side surface 12 of the recess 3. The bottom surface 13 of the recess 3 has a bevel 14 and on the bottom surface 12 there is a flat elastic plate 15 that contacts the bottom edge 16 stop layer 7.

The castle operates as follows

In the open position, the locking plate 7 is loaded in the position shown in FIG. 2, using a spring mechanism (not shown).

When ejecting the door, on which the fixing plate 2 with the lock element 1 is placed, the latter enters the window 5 and enters the forked recess 8 and rotates it on the axis 6 in the position shown in FIG. 3. At the same time, the flat elastic plate 15 comes into contact with the lower face 16 of the plate 7 and limits its rotation. And the casing 4 is in contact with the wedge-shaped movable stop 10, limiting the dead stroke, which may occur in the castle due to technological tolerances or wear.

For reliable operation of the lock, the lower part of the casing 4 is in contact with the bevel 14, which raises the height of the movable support element 1 necessary for normal operation. The design of the lock makes it possible to increase the reliability of operation.
