Description

[Detailed Description of the Invention] The present invention relates to a device for pressing an operating rod of a vehicle locking device.

The present invention reduces the size of the locking device and prevents the vibration of the operating rod so that unpleasant noises are not generated.

The operating rod of a conventional locking device has an open lever attached to the back side of a synthetic resin body, one end of which is pivoted to the open lever, and the other end is a free end. Therefore, looseness at the free end was difficult to avoid. In this case, the conventional method for dealing with the looseness of the operating rod is to prevent the free end of the operating lever from shaking by firmly attaching it to the open lever with as little looseness as possible. However, no matter how firmly the shaft is fixed, there is considerable play, so the present invention uses a lock lever to press the free end of the operating rod. In this case, if the lock lever is made of synthetic resin, the effect of pressing the operating rod will be more pronounced.

To explain with reference to the drawings, reference numeral 1 denotes a synthetic resin body, on the front side of which a cover plate 2 made of a metal plate is abutted, and on the rear side a metal back plate 3 is attached. As shown in the rear view of FIG. 3 and the cross-sectional view of FIG. It is formed in the section 6. An open lever 7, an operating rod 8, and a lock lever 9 are provided concentrated at a portion below the bulging portion 6 on the rear side of the body 1. The front side of the body 1 is formed with a recess 12 for mounting a latch 10 that engages with the striker 4 and a latch 11 that prevents the latch 10 from being reversed. Reference numeral 13 denotes a shaft for attaching the latch 10, which is inserted into a shaft hole 14 formed in the body 1.The rear side of the shaft hole 14 has a cylindrical shape formed by integrally protruding the synthetic resin body 1. shaft cylinder 1
5. Therefore, the shaft 13 can be installed without any play compared to when the shaft 13 is simply inserted into a shaft hole. Similarly, the ratchet 11 also has a shaft 1 inserted into a shaft cylinder 16 made of synthetic resin that protrudes from the body 1.
7' so that it can be installed in the recess 12 without play. Fifth
The figure shows a state in which an open lever 7 and an operating rod 8 are attached to the body 1, and a state in which a lock lever 9 is about to be attached. Approximately midway between the left and right sides of the open lever 7, a shaft cylinder 17 formed by pressing is provided, as shown in FIGS. 7-9. The open lever 7 and the operating rod 8 are formed by punching a metal plate such as an iron plate using a press. When punching the open lever 7, when forming the shaft hole 18, the shaft cylinder 17 is formed by deep drawing. integrally formed. The shaft hole 18 is connected to the shaft 13 of the latch 10 described above.
The open lever 7 has a diameter that fits on the outside of the shaft cylinder 15 that is integral with the body 1 that locks the shaft.
7 is fitted and fixed on the outside of the shaft cylinder 15,
It can be installed without any looseness. The operating rod 8 is formed by pressing a metal plate as shown in FIGS. 10 and 11, and has a shaft hole 19 formed in one end, a long hole 21 in the other free end 20, and a long hole 21 in the middle. It is formed by bending the contact piece 22 at a right angle. As shown in FIGS. 12 to 14, the lock lever 9 is made of synthetic resin, and a shaft cylinder 23 is formed approximately in the middle thereof, similar to the shaft cylinder 17 of the open lever 7, and the shaft cylinder 23 is connected to the body. It fits snugly onto the outer surface of the shaft tube 16 that protrudes from the shaft tube 1. A chevron-shaped engaging portion 24 is integrally formed at one end of the lock lever. 25,
26 is each engagement surface of the engagement part 24. A protrusion 27 is integrally formed on the front side of the lock lever 9, and the protrusion 27 is engaged in an elongated hole 21 formed in the free end 20 of the operating rod 8. When the lock lever 9 is attached to the body 1, the free end 20 of the operating rod 8 is clamped at the front surface thereof. A communication port 28 communicating from the front to the rear is formed in the body 1, and a rod-shaped projection 29 protruding from the ratchet 11 projects from the communication port 28 to the rear surface. The locking lever 9 is displaced between the locking device and the unlocked position as shown in FIGS. 23-24. FIG. 23 shows the unlocked position, where the contact piece 22 formed on the operating rod 8 and the rod-shaped protrusion 29 are in the engaged position, and when the open lever 7 is rotated clockwise as indicated by arrow a, the operating rod 8 moves downward. Then, the rod-shaped projection 29 is pushed down by the contact piece 22, and the engagement of the latch 11 with the latch 10 is released. FIG. 24 shows the lock position, in which the free end 20 of the operating rod 8 is moved to the right, so that the abutting piece 22 and the protrusion 29 are out of position, and even if the open lever 7 is rotated, the ratchet 11 does not move. 25 and 26 illustrate the coil spring 30 that presses against the lock lever 9. FIG. One end of the coil spring 30 is engaged with the engagement piece 31 protruding from the open lever 7, and after being wound around the outside of the shaft tube 17 of the open lever 7, a folded part 32 is formed at the other end, and this Engage with the chevron-shaped engaging portion 24. The outer periphery of the latch 10 provided in the recess 12 is formed with an engagement groove 33 in which the striker 4 engages, and a half engagement step 35 and a full engagement step 36 in which the pawl 34 of the ratchet 11 engages. Ru. Reference numeral 37 denotes a buffer, which is made of a material such as rubber, and is provided so as to cover at least the striker contact surfaces 38 and the engagement surfaces 39 on both sides of the engagement groove 33. It is formed so as to cover the groove bottom surface 40 and the engagement surface 41. In the figure, 42 is a contact surface covering part, 43 is an engaging surface covering part,
44 is a groove bottom covering portion, and 45 is an engaging surface covering portion.

Next, we will discuss the effect.

When the vehicle door is closed, the striker 4 engages with the engagement groove 33 of the latch 10 on the lock body side (Figs. 16 to 18), and the pawl 34 of the latch 11 engages with the full lock engagement step 36. This prevents the latch 10 from being reversed and the door is closed. In this state, when the lock lever 9 is rotated to the lock position shown in FIG. 24, the bent portion 32 of the coil spring 30 will be bent as shown in FIG.
It lands on the engagement surface 25 of the engagement portion 24 and maintains the locked state. Even if the open lever 7 is rotated clockwise and the operating rod 8 is moved, the contact piece 22 and the rod-shaped protrusion 29 of the ratchet 11 are out of position, so the ratchet 11 cannot be removed, resulting in what is called a missed swing. is locked. Next, when the lock lever 9 is placed in the non-locking position (FIGS. 23 and 25), the bent portion 32 of the coil spring 30
engages with the engagement surface 26 of the engagement portion 24 to fix the lock lever 9, moves the operating rod 8 so that its abutment piece 22 faces the rod-shaped protrusion 29, and moves the open lever 7 in the direction indicated by the arrow in FIG. When the latch is rotated to the position a, the rod-like projection 29 is pushed down and the pawl 34 of the latch 11 is disengaged from the engagement steps 35 and 36 of the latch 10, thereby making it possible to open the door.

The present invention is as described above, and in particular, the latch 1 is attached to the recess 12 on the front side of the body 1 made of synthetic resin.
