Abstract

(57) [Abstract] [Purpose] Even if the lock bar that locks the container door and the container handle are hard and difficult to turn, there is no concern that the container handle will break, and a strong rotational force can be applied in a stable posture. Can be given to the handle. [Structure] On a lower surface 3 of a head 1, a handle base insertion groove 2 having a size that can be inserted into a pivotally attached base portion of a container handle is provided in a substantially U-shaped recess in a horizontal direction parallel to the lower surface 3. The side walls 5 and 5 of the head 1 parallel to the handle base insertion groove 2 are provided with pivot attachment insertion grooves 4 and 4 perpendicular to the handle base insertion groove 2. A rotating grip bar 6 is attached to the side surface 5 in a direction perpendicular to the handle base insertion groove 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an auxiliary tool used when opening and closing a door of a container.

[0002]

[Prior art]

 Conventionally, when opening and closing the door of a container, as is well known, with the door handle that rotates sideways unlocked, hold the tip of the door handle with your hand and rotate it with the lock bar to lock the door. It is released and the door is opened and closed.

[0003]

[Problems to be solved by the device]

 According to the method of gripping and turning the front end of the door handle described in the prior art, depending on the type of cargo in the container, the cargo is pressed strongly from the inside to the outside of the door, causing the center of the door to bend and expand. The lock bar that holds the door in place to put it out also puts a heavy load on the door handle, which makes it difficult to turn, and sometimes the door handle may break, and the container is always open outdoors. Since it is exposed to wind and rain, it deteriorates significantly, and when rust etc. occurs, the handle operation to rotate the lock rod further requires physical strength, and the posture to pull the body diagonally and strongly is also unstable There was also a problem that injuries tended to occur. The present invention has been made in view of the above-mentioned problems of the conventional technology. The purpose of the present invention is to reinforce the rotational force of the container handle so that the rotational force is stable and strong. It is intended to provide a container door opening / closing aid that can open and close doors by rotating the lock rod in addition to the container handle.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a container door opening / closing aid according to the present invention is fitted at a central position of a lower surface of a substantially rectangular parallelepiped head, in a horizontal direction parallel to the lower surface, to a pivot base of a container handle from above. The handle base insertion groove of a size that can be inserted is upside down and U-shaped, and the shaft insertion groove opened in the direction perpendicular to the handle base insertion groove on two sides of the head parallel to the handle base insertion groove. Is formed in an upside-down U shape, and a rotating gripping rod is attached to one side surface of the head parallel to the handle base insertion groove, at a right angle to the handle base insertion groove.

[0005]

[Action]

 Grasp the tip of the rotating grip rod with your hand and insert the handle base insertion groove into the pivot base K of the door handle H (see Fig. 4), then grasp the tip of the door handle with one hand, With both hands open, step on with both feet and firmly and stably, you can give a strong and bold turning force to both the tip of the door handle and the pivot base, and the door D moves vertically. The attached lock rod L can be strongly rotated.

[0006]

【Example】

 1 to 4, the head 1 is formed in a substantially rectangular parallelepiped shape. The handle base insertion groove 2 is a U-shaped groove having a vertical cross section that is substantially upside down in the center position of the lower surface 3 of the head 1 in the left-right direction parallel to the lower surface, and the pivot base K of the container handle H can be inserted. It is formed in the shape of a groove. The pivot insertion grooves 4 and 4 are formed in the side surfaces 5 and 5 of the head 1 in the direction parallel to the handle base insertion groove 2 so as to form a U-shaped groove which is substantially upright in a direction perpendicular to the handle base insertion groove 2. One end of the rotary grip rod 6 is fixed to one side surface 5 of the head 1 which is parallel to the handle base insertion groove 2, and is provided in the direction perpendicular to the handle base insertion groove 2. The shape of the outer shape of the head 1 is not necessarily limited to a substantially rectangular parallelepiped shape, and may be formed in a U-shape with an angled vertical cross section, and the handle base insertion groove 2 and the pivot shaft. It is most preferable that the insertion groove 4 has a substantially upside-down U shape, but it is not always limited to this.

[0007]

As described above, when the door opening / closing aid of the container of the present invention is used, it is inserted into the pivot base of the door handle, and the pivot base and the tip end of the door handle are both attached. Because it can give a turning force. Even if the lock bar is difficult to rotate due to curved bulging of the door or various factors such as rust, the door handle will not break, and you can work with a stable posture with your hands and legs spread out, so you may be injured. Without that, a drastic and powerful turning force can be applied to the door handle, which can be expected to improve work efficiency.
