Abstract

[PROBLEMS] In a sea container, the container door is not closed normally due to lack of confirmation when the container door is closed, and a gap occurs between the door and the container body. To prevent. A protrusion (1) is provided on a cam (4) of a container door, and a protrusion (2) is provided on a cam receiver (5). As a result, when the container door is closed, the cam and the cam receiver do not engage with each other, and when the back side of the cam (4) is in contact with the front side of the cam receiver (5), the protrusion (1) is caught by the protrusion (2). Since the handle forms an angle with the door surface, the door handle cannot be hung on the handle rest. As a result, the operation of closing the container door must be performed again, so that incomplete closing can be prevented. [Selection] Figure 8

Description

Detailed Description of the Invention

      The present invention relates to a structure of a cam and a cam receiver which are parts of a container door.

      Some of the import / export containers are incompletely closed as shown in FIG. 17 or 18. FIG. 19 is an enlarged photograph of the part indicated by the arrow (8) in FIG. 17, but when the closing is incomplete, a gap is formed in the part indicated by the arrow (9), and the container is caused by wind and rain during the transportation. Cargo damage such as wetting loss will occur in the cargo inside. If a container with an incompletely closed door is found, it will take time and effort to close the gap with aluminum tape and sealer as shown in Fig. 18, but it will also completely prevent cargo damage. Is not done.

In order to solve this problem, the structure of the cam and the cam receiver is as follows. According to an embodiment based on claim 2, the cam (4) is provided with a protrusion (1) and the cam receiver (5) is provided with a protrusion (2) as shown in FIG. Provide. In this manner, when closing the container doors, without Awa chewing receiving cams and cam, projection as shown in FIG. 13 rotates while contacting the rear surface of the cam (4) on the front of the receiving cam (5) (1) Since the door handle (6) forms an angle with the door surface as shown in FIG. 16, the door handle (6) cannot be hooked on the handle receiver (7). As a result, the operation of closing the container door must be performed again, so that incomplete closing can be prevented. Further, in the cam and the cam receiver of the first aspect, the protrusion (1) is not provided on the cam (4), but when the container door is closed, the lock rod (14) is rotated by the door handle (6) to lock the container door. The cam (4) provided at the upper and lower ends of the rod (14) failed to engage with the cam receiver (5), and the cam (4) rotated while the rear surface of the cam (4) was in contact with the front surface of the cam receiver (5). When the cam (4) has no projection (1), the crotch portion (17) of the claw (12) divided into the two forks of the cam (4) is restrained by the projection (2) of the cam receiver (5). It is what.

    If the protrusion (2) is provided on the cam receiver (5), the protrusion (2) and the cam (4) may interfere with each other as shown in FIGS. Interference can be prevented by providing a recess (3) in the cam (4) as shown in FIGS.

14 is a cross-sectional view as viewed from the left side along the line BB in FIG. 14. In FIG. 11, when a T-shape is imitated on the front surface of the T-shaped member (15) of the cam receiver (5) as shown in FIG. By providing an inclination that inclines in the container body direction from the intersection of the horizontal line to the left and right ends of the horizontal line, and by providing an inclination suitable for the inclination on the rear surface of each of the claws (12) divided into the bifurcated cam (4) when to be Shimeyo container door, if missed engagement receiving cams and cam (4) (5) becomes the projection (1) projection (2) is easily caught.
