Abstract

A support piece (2), with an edge cutout (5) in a plate (2b) for a closing bolt (4) is incorporated in the lock, esp for the luggage compartment door on a vehicle with a rasiable rear flap. Two levers (7) move into the cutout and permit bolt movement between them, and can swing into a closing position. One bears a stop piece (10); and a spring mechanism. Pref is sited between this and the support piece. The stop is moved by an activating device, into a lock-opening position, with its stop face out of contact with the second lever. The latter can be brought into locking engagement by stop piece displacement. This effectively checks closed door movement.

B j The invention relates to locking devices, in particular, to a lock for the rear cargo door of a truck. A lock for a cargo door of a motor vehicle is known that contains a support plate with a seat for constipation, hinged on one side of the saddle. A catch with a notch and two protrusions, one of which is made for contact with the stop surface of the locking element hinged on the plate, and a turn stop capture l. The disadvantage of the known lock is its low reliability when locking, due to the possibility of the door moving and tilting in its closed state relative to the body of the car. The purpose of the invention is to improve the reliability of locking. The goal is achieved by the fact that a lock for a cargo door of an automobile, containing a support plate with a seat for constipation, is hinged on one side of the seat grip with a recess and two projections, one of which is made for contact with the abutment surface. .to the locking element, hinged on the plate, and the grip rotation stop, is provided with a pivot axis mounted on the plate on the opposite side of the saddle and an auxiliary catch fixed on it with a recess for constipation, wherein the auxiliary gripper is pivotally connected to the locking element and has an abutment for contact with another protrusion of the main gripper. In addition, the lock is provided with an auxiliary gripper clamped onto the plate. Fig.1 shows the castle, view in the plate; in fig. 2 - section A-A in FIG. 1, (lock in the open position); fig.Z - the same, in the closed position; Fig. 4 is a section E-B in Fig. 2 (fastener fastening elements). The lock contains a support structure that includes a plate 1, provided with openings 2, which serve to crease the support structure to a car part, a cylindrical lock 3 in FIG. 2 and h) which is intended to interact with the elements of the lock in the supporting structure when locking the car door. The supporting structure can be mounted on the body of the car. In this case, the lock 3 is fixed to the rear door of the car, and vice versa, the supporting structure can be mounted on the rear door, while the lock 3 is attached to the body of the car. The support structure of the lock includes a support plate 4 (FIGS. 2 and 3), which is located in a plane perpendicular to the plate 1 and to the axis of the lock 3. The plate 4 has a seat 5 for the lock 3. The support structure also has two walls 6 that are separated from the edges of the plate 4 on the opposite seats 5 in the direction of movement of the constipation 3 inwards. The walls 6 are inclined towards each other and with respect to the entrance to the saddle 5 for contact with the corresponding spring 7 placed on the lock 3 to direct it to the saddle 5. On the plate 4 it is pivotally mounted on the axis 8 on one side of the saddle gripper 9 with a notch 10 and protrusions 11 and 12. On the opposite side of the saddle 5, on the axis 13, there is a pivotally engaging gripper 14 with a notch 15 for locking 3. In the open position of the lock shown in FIG. 2, the notches 10 and 15 are turned towards the entrance of the saddle 5 and have adjacent closely spaced, covering the pore surface which it covers when it is moved into the saddle and turning the grippers 9 and 14 to the closed position of the lock shown in fkg.Z. In this position; notches 10 and 15 face each other and form a circular opening in which 1 is located constipation 3, adjacent to it almost over the entire outer surface. The support plate 4 has a raised part 16 so that the working surface of the grippers is at some distance from the main part of the plate, allowing them to freely rotate around the axes 8 and 13. On the gripper 14 it is fixed by means of a rotary axis 17 parallel to the B and 13 axes. , resilient locking element 18, which has a thrust surface 19 for contact with the protrusion 12 of the gripper 9; One end of the axis 17 protrudes into the arcuate gap of the plate 4, which allows the axis 17 to move, and therefore the locking element 18 on the gripper 14 around the axis 13.. The locking element is spring-loaded with a coil torsion spring 20, which is attached at one end to the protrusion 21 located on the locking element 18, and the other end to the supporting structure of the lock so that it tends to fiddle; the locking element 18 and zasvat 14, on which it is located, counterclockwise, as from the drawing to the open position of the lock. The locking element and the protrusion 12 are made so that in the open position of the lock (FIG. 2), the edge of the protrusion 12 engages with the supporting surface 19 of the locking element 18, and when the arms are turned to the closed position of the lock (FIG. 3), the protrusion 12

slides along the surface 19 of the locking element 18 and fixes it. in order to hold the grippers in the locked position of the lock.

In order to bring the lock to the open position with IcioMoutH controls (not shown), the locking element 18 is turned counter-clockwise so as to separate its working surface 22 and the protrusion 12. The drive means may, for example, be a Bowden cable, but in the proposed The lock has a button that acts on the protrusion 23, which is provided with a locking element 18. When you press it. button to release the working surface from the hook or with the protrusion 12, the element 18 and the grip 14, to TojxjMy it: Replen / released so as to be able to (return counterclockwise under the spring of the spring 20 to the open polo. Lock Wing At this stage, the support surface 19 of the locking element 18 engages the edge of the protrusion 12 by sliding and turns the grip 9 clockwise to open the lock.

The gripper 14, on which the locking element is hinged, has an abutment 24 / which protrudes from the other gripper 9 dp, acting on its protrusion 11 so that it turns from the closed position to the open position. . , -,, . The movement of the claws to their open position is fixed by the stoppers 25 and 26, which are adjacent to the rachagam. An additional stop 27 serves to limit the movement of the claws to the closed position when the lock 3 is not trapped between the notches 10 and 15. The stops 25-27 are formed by cutting and pressing in the plate 4 itself.

Support 28 on the plate 1 (figure 1); It is designed to install a support for a push button that acts on the protrusion 23 of the locking element 18 in order to open the ZSH4OK. Bearing 28 has two holes, designed for two pins, with the help of which

The button support is set in such a way that the button is fixed in the exact position relative to the supporting structure.

The lock works as follows.

When p; the locked lock position of FIG. 2} it closes and locks the cargo door of the vehicle when the lock 3 moves in the direction of the seat 5 in the direction of the arrow A when the door is closed. When the stop element comes in contact with the gripping surfaces of the recesses 9 and 15, the grippers 9 and 14 are turned towards the closed position (Fig. 3). More precisely, the gripper 14 is rotated clockwise while the hook 9 is rotated counter-clockwise. During this movement, the protrusion 12 slides along the surface 19 of the locking element 18 (resting against the surface 22, fixes the constipation 3 between the recesses of the grippers 9 and 14. The sliding of the protrusion 12 along the surface 22 under the action of the spring 20 provides a tight fit of the gripper 9 to the constipation 3.

When it is necessary to open the lock, the button is pressed to turn the locking element 18 clockwise, which frees the surface from engagement with the spike and allows the bosses to turn to the open position. In the open position (Fig. 2), the clamps 9 and 14 press on.: I locking 3, pushing it out of the saddle 5.: The locking element is usually cylindrical. Preferably, it is with an enlarged head, in order to prevent it from axial P1} slipping between the grippers 9 and 14, when the gage is closed.
