However, in the method of separately providing the protector, the number of parts is increased and the labor for mounting the side door is added, so that the cost is high.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lock handle device for a side door of a container of a cargo truck, which can ensure safety without increasing the number of parts and the mounting time. .

[0006]

The lock handle device for a side door according to the present invention will now be described with reference to the accompanying drawings, in which a lock shaft 9 is rotatably supported by a side door 5 of a container 1. On the side of the latches 16 and 17 fixed to the upper and lower ends of the lock shaft 9, the receiver 1 on the door frame 2 side of the container 1 is provided.
Locking hooks 10 and 11 that engage and disengage with 6 and 17 are projected,
The base end of the operation handle 15 is pivotally connected to a bearing plate 14 provided at an intermediate portion of the lock shaft 9 by a horizontal pivot 35, and
A handle receiving plate 19 to which a distal end of the operation handle 15 is disengaged is fixed to a lower half portion of the base plate 18 fixed to the base plate 18.

A handle stopper plate 21 is pivotally mounted on the upper end of the base plate 18 by a horizontal pivot 24,
A cover plate 33 is provided in the lower half of the handle stopper plate 21 to surround the handle receiving plate 19 and the distal end of the operation handle and to prevent the operation handle 15 from coming out of the handle receiving plate 19, and the side door moves toward the distal end. The cover plate portion 33 is provided with a slope wall portion 33a which is inclined with respect to the traveling direction of the cargo truck so as to approach 5.

[0008]

[Function] To open the side door 5 of the container 1,
After the handle stopper plate 21 is rotated upward along the outer surface of the side door 5 about the horizontal pivot 24 to release the handle receiving plate 19 from the cover plate portion 33 of the handle stopper plate 21, the horizontal pivot 35 is removed. The operation handle 15 is lifted and rotated along the outer surface of the side door 5 as a center. After the tip portion of the operation handle 15 has escaped from the handle receiving plate 19, the operation handle 15 is pulled toward the front side so as to be separated from the outer surface of the side door 5, so that when the lock shaft 9 rotates by a predetermined angle, the latches 12, 13 are locked. Stop hook 10,
11 escapes from the receipts 16 and 17 on the side of the door frame 2. Therefore, the side door 5 is opened and rotated by further pulling the operation handle 15 toward the user.

To lock the side door 5 with respect to the door frame 2 of the container 1, after the side door 5 is closed and rotated, the operation handle 15 is turned down toward the side door 5, and the lock shaft 9 is rotated in the reverse direction. Hook portions 10 and 11 of latches 12 and 13
Are engaged with the receiving members 16 and 17. Thereafter, the operation handle 15 is rotated downward around the horizontal pivot 35 along the outer surface of the side door 5, and the tip of the operation handle 15 is dropped into the handle receiving plate 19. Then, the handle stopper plate 21 about the horizontal pivot 24 is rotated downward, and the handle plate 19 and the operation handle 15 are rotated by the cover plate portion 33.
Surround the tip of.

A pedestrian approaching the container 1 of the cargo truck is guided away from the side door 5 by the inclined wall portion 33a of the cover plate portion 33, so that an accident involving the pedestrian is properly prevented.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A base end of a side door 5 is hinged to a door frame 2 of a container 1 by hinges 3 and 4, and a lock shaft 9 is vertically disposed near a front end of the side door 5, and bearing plates 6 and 7 are provided. , 8 are supported on the outer surface of the side door 5. The base plate 18 is fastened and fixed to the side door 5 at the upper end by a horizontal pivot 24 composed of bolts and a nut 26 screwed to the tip of the horizontal pivot 24, and another set of bolts 25 and nuts 27. The lower end is fastened and fixed to the side door 5.

At the upper end of the base plate 18, there is provided a receiving hole 36 having a so-called oval cross section, which is formed by cutting both opposite sides of a circle in a straight line. The receiving hole 36 also has a collar 22 having an oval cross section.
Are fitted non-rotatably, and the horizontal pivot 24 is inserted into the central shaft hole 37 of the collar 22. Handle stopper plate 2
A shaft hole 30 into which a front end raised portion 32 of the collar 22 is fitted is provided at the upper end of the collar 1, and a collar 2
The two front end ridges 32 are provided with notches 31 that can be disengaged.

After the handle receiving plate 19 and the distal end of the operating handle 15 are covered with the cover plate portion 33, when the hand is released from the handle stopper plate 21, the handle stopper plate 21 moves downward by its own weight and the shaft hole 30 is notched. Part 31 is color 22
In this case, the handle stopper plate 21 does not rotate unintentionally due to vibration of the vehicle body or the like, so that the operation handle 15 is not released.

The cover plate 3 of the handle stopper plate 21
3, the upper surface, the left side surface and the front surface are closed, and the lower surface, the right side surface and the back surface are opened, and the sloped wall portion 33a is formed on the left side surface. A long hole 29 is provided in the front wall of the cover plate portion 33. The handle receiving plate 19 is bent in a stepped parallel plate shape, and the vertical lower side portion 19b is welded to the lower portion of the base plate 18. Operation handle 1
5 is dropped into a pocket formed by the vertical upper side 19c, the horizontal middle side 19a, and the base plate 18 of the handle receiving plate 19.

A lock receiving plate 20 is fixed to the front side of the handle receiving plate 19, and the lock receiving plate 20 is provided with an elongated hole 28 at a position overlapping with the elongated hole 29 of the cover plate portion 33. By passing another locking means such as a padlock hook rod through these long holes 28 and 29, the handle stopper plate 2
1 can also be locked to the base plate 18. The left side of the upper end of the handle stopper plate 21 contacts the side surface of the base plate 18 to guide the vertical movement of the handle stopper plate 21 or to hold the handle case plate 21 in the evacuation rotation indicated by the phantom line. A wall 34 is provided.

[0016]

As described above, in the lock handle device for a side door of the present invention, the handle receiving plate 19 to which the front end of the operating handle 15 engages and disengages is fixed to the lower half of the base plate 18 fixed to the side door 5. Then, the handle stopper plate 21 is pivotally attached to the upper end of the base plate 18 by the horizontal pivot 24, and the handle receiving plate 19 and the tip of the operating handle are surrounded to prevent the operating handle 15 from coming out of the handle receiving plate 19. The cover plate 33 is provided in the lower half of the handle stopper plate 21,
The cover plate portion 33 is provided with a slope wall portion 33a that is inclined with respect to the traveling direction of the cargo truck so as to approach the side door 5 toward the front end. Entanglement accidents are accurately prevented.
As described above, since it is not necessary to separately prepare a protector made of rubber or the like and attach it to the side door 5 in order to ensure safety, it is possible to reduce costs by reducing the number of parts and the labor for mounting.
