Description

[Detailed description of the invention] This invention relates to a lock handle for a side gate of a cargo box.

Generally speaking, in a three-way open type freight vehicle, as shown in FIG.
A lock handle 5 is rotatably provided on a guard frame 4 that stands upright with respect to the floor panel, and the pivot portion 5a of the lock handle 5 is fitted into the notch recess 2 of the locking member 3, By rotating this in a predetermined direction, the locking member 3 is held between the lock handle 5 and the upright guard frame 4, and the side gate 1 is locked.

To release the lock, the above operation is reversed.

However, there are two types of this type of freight vehicle, a high-floor type and a low-floor type, and the heights of the side gates 1 are greatly different.

For this reason, in the low-floor type shown in FIGS. 2 and 3, the lock handle 5 is located inside the front body 6, and when the lock handle 5 is unlocked, the tip of the lock handle 5 is located at the front. Hitting body 6,
There is a risk that the paint, rust preventive, etc. on the front body 6 may be peeled off, or the front body 6 may be damaged.

In addition, in the case of the high-floor type, as shown in FIG. 4, the lock handle 5 is located outside the front body 6, and when the lock handle 5 is unlocked, the lock handle 5
There is a drawback that the side gate 1 hangs downward and gets in the way when the side gate 1 is closed again, making it difficult to reset it smoothly.

In view of the above-mentioned drawbacks of the conventional art, the present invention has been developed to improve and eliminate these drawbacks.

The configuration of the present invention will be explained below according to the embodiments shown in the drawings.

5 to 8, the present invention has a lock handle 5.
A stopper plate 7 which also serves as a washer is attached to the lock handle 5 to hold the lock handle 5 in a predetermined upright position when the lock handle 5 is unlocked.

The stopper plate 7, which also serves as a washer, has a hole 9 that fits into a screw 10 with a half-moon-shaped notch 8 at the tip of the pivot portion 5a of the lock handle 6, as shown in FIG. , Due to this fitting, the stopper plate 7
is regulatedly rotated with the rotation of the lock handle 5,
Moreover, it is fixed by a nut 11.

Moreover, this stopper plate serves as a flat washer, and is approximately egg-shaped with a tip 7a protruding in one direction, so that the tip 7a comes into contact with the frame 13 during the required rotation, preventing further rotation. regulate.

A clamp 12 is attached to a frame 13 in the vehicle width direction that connects the left and right guard frames 4, and pivotally supports the lock handle 5 together with the upright guard frame 4.

The stopper plate 7 has a center of gravity that moves a predetermined amount in the unlocking direction from the perpendicular to the pivot portion 5a when the lock handle 5 is rotated in the unlocking direction (counterclockwise in FIG. 8). (When the lock handle 5 is located in the cutout recess 2 of the hanging member 3 installed upright on the side gate 1 and is in a state where the side gate 1 can be opened, that is, in the unlocked position), the tip 7a is in the vehicle width direction. frame 1 of
3 and hold it in the state shown in FIG.

In this case, since the rotational moment due to its own weight acts counterclockwise on the lock handle 5, it will not rotate clockwise unnecessarily and will not fall or hang down.

Therefore, with the configuration of the present invention, when unlocking the side gate 1, whether it is a high-floor type or a low-floor type, the lock handle 5 can always be held in the unlocked position by using its own weight. The side gate 1 can be easily reset.

In this way, in the present invention, the lock handle, which is rotatably pivoted to the guard frame that stands upright with respect to the floor panel, is fitted into the notch recess of the latch member attached to the side gate of the cargo box. In a device in which the locking member is held between the guard frame and the side gate is locked by rotating, the penetrating end of the pivot portion of the lock handle that passes through the guard frame is cut out in a half-moon shape. A stopper plate for regulating the rotation of the lock handle is fitted onto the screw shaft through the half-moon-shaped notch so as to prevent individual rotation, and the lock handle is tightened and fixed with a nut. When the lock handle is rotated a predetermined amount in the lock release direction, the stopper plate comes into contact with the frame and restricts further rotation of the lock handle, so even if it is a high-floor type or low-floor type freight vehicle, the side gate can be easily removed. When unlocking, the lock handle can always be held in the unlocked position.

Therefore, the lock handle does not come into contact with the front body and remove paint or rust preventive, or damage the front body as in the past, and the lock handle hangs down and does not get caught between the side gate and the guard frame when resetting. Workability and operability are good because there is no chance of damage.

Moreover, the installation of this device is extremely simple, without requiring any troublesome adjustments such as mounting, and the stopper plate also acts as a washer, so this part does not loosen and maintains its function for a long time. It is something.
