Description

[Detailed description of the invention] The present invention relates to a sliding door for a pan-type automobile, and more specifically, to a sliding door equipped with a locking mechanism that can reliably hold the sliding door in an open state with a simple operation. .

Generally, a pan-type automobile has a body 1 as shown in Fig. 1.
By rotating the door handle 3 at the rear of the sliding door 2 located in the center of the side surface, a sliding door lock device (not shown) is engaged with a door striker (described later) provided at the rear of the sliding door opening of the body 1. At the same time, the sliding door 2 is opened by pulling the door handle 3 toward you to lift the sliding door 2 from the body 1 and sliding it toward the rear. As shown in the figure, the pulley 4 of the sliding door 2 rides on a plate spring 6 provided in the guide rail 5 to maintain the door open state.

However, it is difficult to adjust the spring force of this spring-type stopper for opening the door, and if the spring force is strong, the filling will be poor on flat ground, while if the spring force is weak, it may cause the car to land on a slope. The reality is that no effective countermeasures have been taken, despite the fact that when the sliding door is open, there is a high risk that the sliding door will move due to the weight or impact of the opening and close automatically.

For this purpose, as shown in FIGS. 3A and 3S, a U is fixed at both ends to the rear outer slope 1a of the sliding door opening 9 of the podium 1 when the door is opened, on the inner plate of the front part 2b of the sliding door 2. A hook portion 11 that can be engaged with the letter-shaped door striker 10 from above.
A lock lever 12, which is formed at the tip thereof, is rotatably supported by a pin 13 for the inner handle 14, and when the sliding door 2 is closed, the lock lever is rotated by its own weight to the position shown by the dashed line in the figure. 12 has been proposed in which the hook portion 11 of the sliding door 2 is manually engaged with the door striker 10 to maintain the open state of the sliding door 2 when the door is opened. 12, there was a problem of poor operability.

This invention was made in view of the above-mentioned conventional problems.
To provide a pan-type automobile sliding door equipped with a locking mechanism that can securely hold the sliding door in an open state with simple operation by pulling, pushing, or rotating an operating lever.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The locking mechanism A when opening the door shown in FIGS.
It is adapted to a door striker 22 having a flat flange 22a and a shaft portion 22b provided in the front part 2b of the sliding door 2, and when the door is opened, the recess 23 A lock lever 25 is rotatably supported by a pin 26, and has a notched groove 24 at its tip that protrudes from the shaft portion 22b of the door striker 22 and can be engaged with the shaft portion 22b of the door striker 22 from the side. recess 27 provided in
A rod 30 connects the bush/pull knob 28 housed inside the lock lever 25 with the inward rising edge 29a of the lock lever 25, while a spring force is applied to the lock lever 25 as the lock lever rotates. A dead reversal spring 31 whose acting direction is reversed is provided.

Therefore, when the sliding door 2 is opened, if the knob 28 of the recess 27 of the sliding door 2 is pulled, the lock lever 25 inside the recess 23 will rotate counterclockwise in the figure, and the notch groove 24 will open the door. It comes to engage with the shaft portion 22b of the striker 22.

In this case, the dead reversal spring 31 allows the lock lever to
The positioning of the engaged/disengaged position of the door striker 25 is made more reliable, and the door striker 22 does not easily come off even if it vibrates or comes into contact by mistake.

In addition, since the knob 28 is provided on the side surface 2d of the sliding door 2, it becomes inoperable when the sliding door 2 is closed, which prevents erroneous operation. , knob 28
The knob 28 can be automatically returned to its original position if the tip is pressed against the pillar 32 in front of the sliding door opening 9.

In this locking mechanism A, as shown in FIG. 4C, if the lock lever 25 is provided with an outward rising edge 29b, the lock lever 25 can be engaged with the striker 22 when the knob 28 is pressed. .

Furthermore, the locking mechanism B when the door is opened shown in FIGS. The shaft portion 22 of the door striker 22 having the same structure as above protrudes.
At b, a lock lever 35 having a notch groove 34 formed at its tip that can be engaged from above is attached to a rod 37 rotatably supported at both ends by support angles 36, as shown in FIG. 5C.
is fixed to the distal end side of the rod 37, and at the rear end of the rod 37,
A rotating knob 39 is attached to be housed in a recess 38 provided on the side surface 2d of the sliding door 2.

In the case of this locking mechanism B, rotating the rotating knob 39 counterclockwise in the figure locks the bar 3 in the recess 33.
5 is also rotated counterclockwise, and its notch groove 34 comes to engage with the shaft portion 22b of the door striker 22.

Note that, similar to the lock mechanism A above, the dead reversal spring 3
1 may be provided on the lock cover 35, and the rotation knob 37 also becomes inoperable when the sliding door 2 is closed.

The door striker 22 in this locking mechanism B is the fifth door striker 22.
The above-described U-shaped door striker 10, which is shown in detail in FIG. d, can also be employed.

Further, when the door is opened, the locking mechanism C shown in FIGS. The lock lever 25 having a notch groove 24 that can be engaged with the shaft portion 22b of the door striker 22 is attached to the pin 26.
While the lock lever 25 is rotatably supported,
It is constructed by integrally providing an inward hand raising riser 40.

In the case of this locking mechanism C, the inner surface 2 of the sliding door 2
When the riser 40 is rotated counterclockwise in the drawing from the c side, the lock lever 25 is also rotated, and its notch groove 34 comes to engage with the shaft portion 22b of the door striker 22.

In addition, as shown in FIG. 6C, if the hand raising stand 41 is provided on the side surface of the sliding door 2, it becomes inoperable when the sliding door 2 is closed.

As is clear from the above explanation, the present invention enables the lock lever to be used for the sliding door locking device when opening the sliding door by pulling/buttoning or rotating the operating lever provided at the front of the sliding door. Since the sliding door can be engaged with the door striker to keep the sliding door open, even if the car is placed on a slope, the opened sliding door will be securely locked. , cargo handling operations can be carried out safely.

In addition, the locking mechanism can be locked and unlocked with a simple operation of the operating lever, and the structure is extremely simple, so it has various advantages such as low manufacturing costs.
It has great practical value.
