Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating device for a sliding door latch device for an automobile.

As shown in Figure 1, the so-called sliding door, which is opened by sliding the door A backward along the outer panel B of the vehicle body, is generally installed on the vehicle body side with the front end of the door A above and below. A center guide rail C that is guided by the upper and lower guide rails and whose rear end center portion is provided on the vehicle body side outer plate B.
When the door is in the closed state as shown in the figure, a latch device D installed at the center of the rear end of door A engages with a striker on the vehicle body to maintain the closed state. By operating the outer handle or the inner handle, the latch device D can be unlatched via the operating device E and the connecting member F such as a rod, and the locking member G such as the inner lock knob can be unlatched. By locking the operating device E.
When the connection between the holder and the connecting member F becomes disconnected, an unlatched state becomes impossible, that is, a locked state.

The operating device E generally includes an unlatch operating lever that rotates when the outer handle or the inner handle is operated, a linking lever that operates when the unlatch operating lever rotates and operates the connecting member F in the axial direction, and a locking operating member G. Usually, it is constructed by a combination of three levers, including a lock lever which is rotated by the locking operation of the lever to rotate the linking lever and release the engagement between the linking lever and the linking member F.

The present invention aims to reduce the number of parts of the above-mentioned operating device and simplify the configuration and assembly man-hours, and will be described below with reference to the accompanying drawings.

In FIGS. 2 to 4, reference numeral 1 denotes a base plate attached to the inner panel of the door, and the base plate 1 has an unlatch operating lever 2 attached to the shaft 21.
It is mounted so that it can be rotated.

The shaft 21 is provided with an engaging portion 21' that engages with the unlatching operation lever 2. An inner handle (not shown) is attached to the shaft 21, and by rotating the inner handle, the engaging portion 21' is adapted to push the unlatch operating lever 2 and rotate it in the unlatching direction (clockwise in FIG. 2), and the pressing part 22 is pushed by operation of the outer handle (not shown) and rotates in the unlatching direction as described above. It's starting to move.

A lock lever 3 is attached to the unlatch operation lever 2 so as to be rotatable about a shaft 31.

The lock lever 3 has a hook portion 32 that engages with one end of the connecting member F, and an arm portion 33 that rotatably pivots the tip of a locking operation member G such as an inner lock knob.

The other end of the connecting member F is connected to the latched state holding member of the latching device D as shown in the first figure, as in the conventional case, and by pulling the connecting member F to the left in FIG. It is possible to release the hold and make it into an unlatched state.

The end portion of the connecting member F that engages with the lock lever 3 is inserted into and supported by the holding portion 11 of the base plate 1 so as to be slidable approximately along the axial direction, and the rotation center O of the lock lever 3 by the shaft 31 is located at the holding portion 11 of the base plate 1. The connecting member F is disposed so as to be located substantially on an extension of the axis of the connecting member F supported by the connecting member F.

Further, the unlatch operation lever 2 is held pressed against the stopper part 12 of the base plate 1 by the return spring 4 via the engagement part 21', and the lock lever 3 is held pressed against the stopper part 23 provided on the unlatch operation lever 2 by the reversing spring 5.
It is designed to be held in the unlocked position where it is pressed against the stopper part 24 and the locked position where it is pressed against the stopper part 24, respectively.

The pivot point 33' between the locking lever 3 and the locking operation member G is located above the axis of the connecting member F in the figure, that is, at a position close to the shaft 21 of the unlatching operation lever 2, so that the unlatching operation lever 2 can be rotated in the unlatching direction. The structure is such that the displacement of the shaft attachment point 33' in the left-right direction at the time of locking operation is made as small as possible, and the swing width of the locking operation member G is made small.

In the above configuration, when the outer handle or the inner handle is rotated in the state shown in the second figure,
The unlatch operation lever 2 and the lock lever 3 which is pivotally attached to the unlatch operation lever 2 and whose hook portion 32 is held in a state engaged with the connecting member F by the reversing spring 5 are connected to the shaft 2.
1 in the clockwise direction in FIG. 2, and the connecting member F can be pulled into the unlatched state.

When the locking operation member G is pushed down by operating a key from inside or outside the vehicle in the state shown in FIG. 2, the lock lever 3 rotates clockwise in FIG.
It is held pressed against the stopper part 24 by this. In this state, the hook portion 32 has come out of the engagement portion of the connecting member F, and the connection between the lock lever 3 and the connecting member F has been released, and the unlatch operation lever 2 can be rotated by rotating the outer handle or the inner handle. Even if it is, the connecting member F will not be able to be latched, resulting in an unlatched state, that is, a locked state.

When the locking operation member G is pulled upward by a key operation from inside or outside the vehicle, the lock lever 3 rotates around the shaft 31 and returns to the state shown in the second figure, and the hook portion 32 engages with the connecting member F. It can be in an unlatched operable state, that is, in an unlocked state.

As described above, according to the present invention, one lock lever can perform the functions of the conventional two levers, the linking lever and the locking lever, and the predetermined action can be performed using only two levers, the unlatching operation lever and the locking lever. By creating a structure that satisfactorily fulfills the above requirements, it is possible to reduce the number of parts and assembly man-hours, which not only reduces cost and weight, but also makes the entire operating device smaller and more compact. By arranging the rotation center of the lock lever to be located almost on the extension of the axis of the connecting member, the operating force during the unlatching operation is easily and efficiently transmitted to the connecting member, and no rotational torque is generated in the lock lever. , which can maintain reliable operability and can bring about great practical effects.
