Abstract

PROBLEM TO BE SOLVED: To easily release a locked state by remote operation. SOLUTION: This device connects a cam plate 9 to a support bar 7 of a stopper 6 which links to a lock hole 4a of a slider 4 and stops the slider 4 against a guide cylinder 3. And the stopper 6 exerted by a compression spring is housed in a cylinder 5, two surfaces 9a, 9b of a cylinder of a base end portion of the cam plate 9 are contacted alternatively to a head portion 5a of the cylinder 5, and an operation wire 12 with a finger-hooking ring 13 is attached to the tip portion of the cam plate 9.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stay device for fixedly holding a door lifted by a driving means such as a gas damper at a fixed opening angle in a truck bed container or the like.

[0002]

2. Description of the Related Art In a conventional stay device, since a release mechanism of a stopper mechanism for stopping a slider with respect to a guide cylinder is directly attached to a side surface of an upper end portion of the guide cylinder, a guide cylinder is required to release the stopper mechanism. Must be able to reach the top of the Therefore, when the stay device is installed at a high position on the fixed frame, it is difficult to release the lock, and the operator has to jump on the floor of the loading platform and perform the releasing operation while stretching out.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a stay device with a stopper mechanism that can easily release a lock by remote control.

[0004]

A stay device with a stopper mechanism according to the present invention is rotatably mounted on a fixed frame 1 by a guide tube mounting bracket 14. A guide cylinder 3; a slider 4 having one end rotatably mounted on the door 2 by a slider mounting bracket 15 and the other end inserted into the guide cylinder 3.
And a cylinder 5 fixed to the upper end of the side surface of the guide cylinder 3
And fixed to the stopper-supporting rod 7 and inserted into the cylinder 5, urged by the compression spring 8 in the direction of protruding into the guide cylinder 3, and the tip end of the lock hole 4 of the slider 4.
a cam plate 9 whose base end is connected to a portion of the stopper support rod 7 protruding from the cylinder 5 by a pivot 10; 11 and an operation wire 12 with a finger ring 13 attached to the lower end thereof. The cam plate 9 rotates about the pivot 10 so that one surface 9a of the base end of the cam plate 9 is the head of the cylinder 5. When the stopper 6 comes into contact with the portion 5a, the stopper 6 escapes from the lock hole 4a,
The dimension is set so that the stopper 6 engages with the lock hole 4a when the other surface 9b of the base end of the cam plate 9 contacts the head 5a.

[0005]

FIG. 5 shows a stopper mechanism at the time of locking. When the stopper 6 engages with the lock hole 4a of the slider 4, the movement of the slider 4 with respect to the guide cylinder 3 is restricted, and the door 2 is fixed and held at a predetermined open angle as shown in FIG. You. The engagement between the stopper 6 and the lock hole 4 a is maintained by the bias of the compression spring 8.
At this time, the cam plate 9 connected to the stopper-support rod 7 is attracted to the head 5a of the cylinder 5 by the action of the compression spring, and comes into contact with the head 5a at the other surface 9b of the base end. I have.

When the finger ring 13 of the operation wire 12 is pulled downward from the door opened state, the cam plate 9 rotates clockwise around the pivot, and the one surface 9 of the base end of the cam plate 9 is rotated.
a contacts the head 5 a of the cylinder 5. Since the distance between the pivot 10 and the one surface 9a is set to be sufficiently longer than the distance between the pivot 10 and the other surface 9b, the stopper 6 is pulled into the cylinder 5 against the bias of the compression spring 8. It is. Therefore, the tip of the stopper 6 comes out of the lock hole 4a of the slider 4, and the lock of the slider 4 is released. When the door 2 is closed and rotated about a hinge shaft (not shown), the slider 4 is stored in the guide cylinder 3. Then, when you release your hand from the finger ring 13,
The stopper 6 is fixed while being pressed against the side surface of the slider 4 by the compression spring 8.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The length of a wire 12 used for remote control is appropriately set so that a finger ring 13 is located close to a worker of normal height. In addition, the door 2 can be fixedly held at a plurality of open angles by placing a plurality of lock holes 4a on the slider 4 along the length direction. The lower end of the guide tube 3 is a shaft pin 16
The guide tube mounting member 14 is fixed to the fixed frame 1 such as a pillar portion of a container of a truck by a fixing member such as a screw passing through the through hole 14a. The upper end of the slider 4 has a shaft pin 18
Is connected to the slider mounting bracket 15 by
The slider mounting bracket 15 is fixed to the door 2 such as a container by a fixing tool such as a screw passing through the through hole 15a.

[0008]

In the stay device with the stopper mechanism of the present invention configured as described above, even when the stay device is installed at a high position, the length of the operation wire 12 is appropriately adjusted and placed. Since the lock of the stopper mechanism can be released only by pulling the finger ring 13 at hand, the release operation can be performed easily and quickly without the need for the operator to jump on the floor of the loading platform.
