[Technical background of the invention and its problems] For example, in a wagon type car, an opening is formed on the side of the car body, and this opening is a sliding door that is slidably supported on the car body. It is designed to be opened and closed. The conventional sliding door lock device has a second door lock device.
As shown in the figure, an operating mechanism 3 is provided near the outside handle 2 of the sliding door 1, and a latch 4 is provided apart from the operating mechanism 3.
and an open rod 5 that connects this latch 4 and the operating mechanism 3. The operating mechanism 3 is constructed as shown in FIG. In the figure, reference numeral 6 denotes a base of the operating mechanism 3. A rotary shaft 7 is protruded from the base 6, and a first lever 8 and a second lever 9 are rotatably attached. A pressed portion 10 is formed at the upper portion of the first lever 8 so as to protrude laterally. and,
This pressed portion 10 is the outside handle 2
It is pressed as shown by the arrow by a handle lever 11 as a pressing part which is interlocked with the handle lever 11 . Further, the pressed portion 1 of the first lever 8
A long hole 12 is formed between the support shaft 7 and the support shaft 7, and a lower end 13a of a control rod 13, which will be described later, is attached to this long hole 12. The lower end 13a of this control rod 13 is connected to the elongated hole 1.
2 along the circumferential wall in the longitudinal direction. The second lever 9 is attached to the outside of the first lever 8, and one end of the open rod 5 is attached to the upper end. A coil spring 14 is attached to the lower end of the second lever 9 to rotate the second lever 9 clockwise. Further, the second lever 9 is provided with a through hole 15 that faces the elongated hole 12 of the first lever 8, and a relief portion 15a is provided on the lower left side of the hole 15. An inside lock lever 16 is attached to the upper part of the base 6. This inside lock lever 16 is rotatable around a pin 17 provided on the second lever 9 side.
On the opposite side of 7 is an inside lock rod 19 with a knob 18 on the top. The knob 18 projects above the mounting portion 20. The upper end of the control rod 13 is connected to the middle portion of the inside lock lever 16.

Note that 21 is the third switch for releasing the locked state.
This is the lever.

In the conventional door lock operation device for a sliding door configured as described above, when the knob 18 is pressed down and locked, the outside handle 2 is operated, and the handle lever connected thereto is operated. 11 moves like an arrow,
When the pressed portion 10 of the first lever 8 is pressed and the first lever 8 attempts to rotate around the support shaft 7, the lower end 13a of the control rod 13 located at the lower end of the elongated hole 12 is opened through the hole. 15, the first lever 8 and the second lever 9
does not rotate and the open rod 5 does not actuate the latch 4, so the locked state is maintained as it is.

Next, when the knob 18 is pulled upward to the unlocked state shown in FIG. Move to. After that, when the handle lever 11 presses the pressed portion 10 of the first lever 8, both the first and second levers 8, 9 rotate around the support shaft 7, so that the open rod 5
moves in the direction of the arrow, the latch 4 is actuated, and the sliding door 1 can be opened.

However, since the operating mechanism 3 of the above-mentioned conventional structure selects the locked state and unlocked state using the inside lock lever 16 and the control rod 13 interlocked therewith, not only the operation becomes unstable but also the number of parts increases. There were flaws.

[Purpose of the invention] This invention was made in consideration of the above circumstances, and its purpose is to provide a door lock operating device for a sliding door that operates smoothly and requires a small number of parts. It is.

[Summary of the invention] In this invention, the operating mechanism of the door lock operating device of the sliding door is such that the first lever that is linked to the outside handle of the sliding door can be directly moved up and down by the inside lock rod, and when lowering, the first lever is moved up and down directly by the outside handle. Even when the handle is operated, the handle lever as a pressing part does not come into contact with the first lever, and the locked state is maintained, and when the first lever is raised, when the outside handle is operated, the handle of this outside handle The lever is configured so that it comes into contact with the pressed portion of the first lever and rotates it, thereby bringing it into the unlocked state.

[Example of the invention] An example of this invention is shown in Figs. 2 and 5 below.
The explanation will be made with reference to FIGS. 1 to 4, in which the same components are given the same reference numerals. In the figure, 30 is a first lever, and 31 is a second lever. Then, the first lever 30 is placed on the base 6 side, and the second lever 3
1 is provided on the outside of the first lever 30.
In addition, the first lever 30 is guided by the second lever 31 and is movable up and down, and is rotatable about the support shaft 7 protruding from the base 6, whereas the second lever 31 is rotatable around the support shaft 7. As shown in FIG. 3, the first lever 30 is provided with a U-shaped bent portion 32 extending downward to the right on the opposite side of the pressed portion 10. As shown in FIG. A mounting hole 33 is provided near the lower end of this bent portion 32 .

Furthermore, the first lever 30 has the above-mentioned mounting hole 33.
An elongated hole 34 that is long in the vertical direction is bored facing the. The support shaft 7 is fitted into the elongated hole 34 as shown in FIG. 1a. That is, as described above, the first lever 30 is guided by the second lever 31 and can freely move up and down, but when descending, the mounting hole 33 is inserted into the lower end of the elongated hole 34 as shown in FIG. 1a. When the mounting hole 33 is raised, the mounting hole 33 faces the support shaft 7, as shown in FIG. 1b. In other words, the length of the elongated hole 34 in the longitudinal direction is the same as that of the first lever 3.
It is equal to the vertical stroke of 0. Furthermore, a projection 35 is provided at the upper end of the first lever 30 and is bent outward at a right angle. This protrusion 35 is fitted into a guide groove 36 provided on the second lever 31 to guide the vertical movement of the first lever 30. The lower end of the inside lock rod 37 is attached to the attachment hole 33 of the U-shaped bent portion 32 of the first lever 30 via a pin 38. This inside lock rod 37 is bent into a dogleg shape, and a knob 18 is attached to its upper end.

In this device configured as described above, when the knob 18 is pushed down as shown in FIG.
The lever 30 is lowered, and the pressed part 10, which had been facing the handle lever 11 as a pressing part, is moved down.
Since the handle lever 11 no longer faces the handle lever 11, even if the outside handle 2 is operated, the handle lever 11 swings in vain above the first lever 30.
The first lever 30 does not rotate. Therefore, the second lever 31 also does not rotate, and the open rod 5 does not operate. Therefore, the latch 4 also does not operate, so the sliding door 1 is locked.

Next, as shown in FIG. 1b, when the knob 18 is pulled up, the first lever 30 rises, its pressed portion 10 faces the handle lever 11, and the support shaft 7 is inserted into the elongated hole 34. It touches the bottom end. At this time,
When the outside handle 2 is rotated, the handle lever 11 presses the pressed portion 10, and the first lever 30 rotates about the support shaft 7. As a result, the second lever 31 rotates together with the first lever 30 via the protrusion 35 of the first lever 30,
actuating the latch 4 via the open rod 5;
The sliding door 1 is released to be in an unlocked state.

[Effects of the invention] As explained above, in this invention, there is an operating mechanism provided near the outside handle, a latch provided separately from this operating mechanism, and a link between the latch and the operating mechanism. In the door lock operating device for a sliding door, the operating mechanism is configured to directly move a first lever, which has a pressed portion opposite to a pressed portion that interlocks with an outside handle, up and down by means of an inside lock rod. It is configured so that it can be unlocked and locked by moving the pressed part toward or away from the pressing part of the outside handle, eliminating the need for the conventional inner lock lever and control rod. This has the effect of making it easier and more reliable.
