Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cargo fastening device in which a fastening member such as a belt or a rope that binds luggage can be easily opened.
[0002]
[Prior art]
For example, when fixing a load to a vehicle bed with a tightening member, a ratchet type tightening device is used, and the reversing of the gear is regulated by the ratchet pawl, and the gear is rotated to tighten and tighten the tightening member. Yes. In order to release the load tightening, the ratchet pawl is removed after the gear is rotated in the tightening direction.
[0003]
[Problems to be solved by the invention]
However, the ratchet-type loading device cannot be opened quickly, and it is difficult to open the loading site when the loading site is at a high position due to the rising of the loading platform or the like. In addition, there is a means for pulling out the hinge pin of the hook on which the tightening member is hung. However, if the tension of the tightening member is large, the frictional force increases and the pin does not come off.
[0004]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cargo tightening device capable of quickly and easily releasing a cargo tightening member.
[0005]
[Means for Solving the Problems]
In order to achieve the above-described object, a loading device according to the present invention includes a hook provided on one end of the arm so as to be able to be tilted and a hook provided on the other side of the tip of the arm so that the hook can be raised. A locking member that regulates, and provided on the locking member is a turn restricting means that engages with the arm to restrict the turning of the locking member so as to be able to advance and retreat, and to turn the locking member in the opening direction It is characterized in that it is provided with a raising means. Moreover, a rope can be connected to the rotation restricting means and the raising means, respectively.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment in which the present invention is applied to a loading platform on which a transport cart stands will be described based on the drawings. In the loading device 1, an arm 4 is provided on a mounting plate 3 on the side surface of the loading platform 2 so as to be rotatable about a support shaft 5 in the longitudinal direction of the loading platform. The arm 4 has a hook 6 provided on one side of the tip so as to be able to rise and fall, and a lock member 7 provided on the other side of the tip so as to be rotatable so as to restrict the standing of the hook 6.
[0007]
The hook 6 is formed in a substantially U shape having a recess 6a into which a tightening member such as a belt or a rope is inserted. The hook 6 is provided on a support shaft 8 orthogonal to the support shaft 5 so as to be tilted and locked. The opening of the recess 6a faces sideways when tilted to the member 7 side, and the opening of the recess 6a faces upward when the stopper 6b stands on the arm 4 and stands up 90 degrees.
[0008]
The lock member 7 is rotatably provided on a support shaft 9 in the same direction as the support shaft 8, and the end surface of the arm 4 on the lock member 7 side is formed in an arc centered on the support shaft 9. . Further, the lock member 7 is inserted into the recessed portion 6a of the hook 6 that has been tilted, and has a roller follower 10 that restricts the standing of the hook 6, and also engages with the end face of the arm 4 to restrict rotation. A pin plunger 11 is provided as a regulating means. The tip of the pin plunger 11 is always advanced toward the end surface of the arm 4 and engaged with the end surface of the arm 4. When the eye nut 12 is pulled, the tip is retracted and the engagement with the end surface of the arm 4 is released. . Further, an eye bolt 13 is provided at the tip of the lock member 7 as a pulling means for rotating the lock member 7 in the opening direction. An operating rope can be connected to each of the eye nut 12 and the eye bolt 13.
[0009]
In the load tightening by the load tightening device 1 configured as described above, the tightening member is inserted into the recessed portion 6a of the hook 6 that has been tilted, and the lock member 7 is rotated to insert the roller follower 10 into the recessed portion 6a. Thereby, since the standing of the hook 6 is regulated, the tightening member is tensioned and loaded. When releasing the load tightening, when the eye nut 12 and the eye bolt 13 are pulled, the lock member 7 is rotated and the hook 6 is raised by the tension of the tightening member, and the tightening member is released.
[0010]
Therefore, the release of the load can be quickly and easily performed. In particular, even when the loading platform 2 as shown in FIG. 2 is raised or when the loading platform is raised, an operation rope is attached to the eye nut 12 and the eye bolt 13. Just install it. In addition, although the said embodiment demonstrated the load-clamping apparatus attached to the loading platform of a conveyance trolley, this invention is applicable also to the loading of the slinging wire of a crane.
[0011]
【The invention's effect】
As described above, the load tightening device according to the present invention is a circuit that engages the arm and restricts the rotation of the lock member to the lock member that restricts the rising of the hook provided at the tip of the arm so as to be able to rise and fall. Since the movement restricting means is provided so as to be able to advance and retract, and the pulling means for rotating the lock member in the opening direction is provided, when the rotation restricting means and the pulling means are pulled, the hook stands up due to the tension of the tightening member. Thus, the tightening member is released, so that the load can be released quickly and easily. Further, by connecting the ropes to the rotation restricting means and the raising means, it is easy to release the load tightening even if the load tightening portion is at a high place.
