Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door lock device for a vehicle. Generally, the middle part of the oven plate is pivotally supported by the case, which restricts the placement of the ratchet and the swing radius of the oven plate is small, but the direction of the force applied to both ends is opposite. Therefore, the inner handle and the outer handle, which are connected via a lever, are difficult to operate and the interlocking mechanism thereof is complicated.

The purpose of the present invention is to improve this inconvenience, and the oven plate is rotated using its entire length as a swing radius, thereby making it easier to arrange the long chute and also applying the force required during the swing. The direction of the handle is made substantially straight so that the handle operation associated with this direction can be performed smoothly.

To explain this with reference to the illustrated embodiment, (1) indicates a latch, and the latch (1) is connected to the intermediate wall (2a) of the case (2).
It is pivoted via a support shaft (3) provided on the case (2), and the reaction is carried out via a spring (6) that is suspended between a pin (4) protruding from the back of the support shaft (3) and a bottle f51 provided on the case (2). A striker (7) is energized to rotate clockwise and is provided on the outer periphery of the vehicle body.
Fork teeth (1a) that mesh with the ratchet (to be described later)
A first stage part (1b) of a half lock and a second stage part (1c) of a full lock are provided, which engage with the second stage part (1c) of a half lock. (8)
indicates a ratchet, and the ratchet (8) is connected to the middle septum (
The spring receiver (8a) and the intermediate partition wall (2a) are pivotally supported via a support shaft (9) provided in 2a) and protrude from the outer periphery of the support shaft.
A spring receiver a recessed in the spring is biased to rotate clockwise via a spring αυ interposed between the spring receiver a, and the first step part (1b) and second step part of the latch (1) are attached to the outer periphery of the spring receiver a. A claw piece (8b) to be engaged with the step part (1c) and a piece (8C) for holding a slider (12+, which will be described later) are provided. (12+ indicates a slider, and the slider az (2a) is in contact with the front surface of the ratchet (8), overlaps with the back surface of the ratchet (8), and is fitted into the spindle (9) via a U-shaped leg piece (12a) formed at one end of the ratchet (8). , the holding piece (8C) via the guide side (12b) formed on the lower side thereof.
and a lock brake (to be described later) on the other end.

The through hole formed in 2a) and the open bra (described later) (
A projecting piece (

A square hole (13a) communicating with the through hole formed in the intermediate partition wall (2a) is provided in the middle, and the winding is suspended between the center of the upper side of the square hole (13a) and the support shaft (3). It is suspended via the spring Q61, and the slider (

A regulating protrusion (13c) for regulating the lateral movement of the member 1 is provided. aη indicates a lock plate, and the plate α7) is supported by a support plate Oa fixed to the back surface of the intermediate partition wall (2a) and connected to a lock knob and a cylinder lock (not shown), and has a projecting pin ( 17, 1) is passed through the square hole (13a) of the open plate (13) and fitted into the ring groove (12c) of the slider housing z.

Next, the operation will be explained with reference to the operation diagram shown in Fig. 5. In the door open/unlocked state shown in Fig. 5 (a) where the striker (7) does not engage with the latch (1), the pawl (8b) of the ratchet (8)
are disengaged from the engagement steps (1b) (1c) of the latch (1) and come into contact with the circumferential side of the latch (1), and the slider (121)
) The protruding piece (12d) abuts the i-side protruding piece (13C) of the open plate (13), making it impossible to slide the slider az in the lateral direction by operating the lock plate aη. To perform keyless locking from the following state, press down the open plate α3) by operating the inner handle or outer handle of the hatch, disengage the regulating protrusion (15a) from the protrusion (12a) of the slider (121), and then lock the lock knob. By rotating the lock plate (17) by sliding the slider α2 in the lateral direction, keyless locking is possible in which the locked state is achieved without using a key.From the state shown in FIG. ) and the ratchet (8) in the flocked state.
The claw piece (8b) is the latch (first step part (1b) of 11).
As the slider αZ rotates to engage with the rotation, the slider αZ also rotates and finally falls into the half-lock step, and the protrusion (12(L) is an open play) (the regulating protrusion of 131) This state is the same even in the fully locked state in which the pawl (8b) of the ratchet (8) in Figure C is engaged with the second step (1C) of the latch (1).

Therefore, when the open plate 0:1 is swung by operating the inner handle or the outer handle in this fully locked state as shown in FIG. In order to rotate the slider (121) together with the ratchet (8) and disengage the claw piece (8b) from the engagement step (1C), the latch (11 is moved to the door open position as the striker is removed). However, in the full lock state shown in figure C, the slider α2
In order to enable the lateral movement of the lock brake (lη), the slider (121 slides as shown in e in the figure) and its protrusion ( 12d) is an unlocking protrusion with an open plate (
13b) by operating the inner handle or outer handle to move outside the rotation locus), (
131 swings in vain as shown in figure f, and the door is not unlocked.

In this way, according to the present invention, open play) (13
) is suspended in the case (2) via the winding spring (161) that is locked at the middle upper part, so the plate (1
31 is pivotally supported in the middle part, and the slider (
It facilitates the arrangement of the ratchet (8) that is interlocked via the 12 This has effects such as making the operation easier and simplifying the interlocking mechanism.
