DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lead-acid battery carrying structure.

[0002]

2. Description of the Related Art Various leaders are used in general lead-acid batteries in order to make them easy to carry. Among these various types of hands, as shown in FIG.
Is used. That is, a method is used in which the string for the lead-acid battery is passed through the mounting hole 3b formed in the lid 2 of the lead-acid battery, and then the ends are tied to form a knot 9, thereby functioning as a hand for the lead-acid battery. Things.

[0003] However, when this method is used, the work of tying the ends of the string is required, and the man-hour is required. Further, these hands are required only when the lead-acid battery is carried, and become unnecessary after the lead-acid battery is attached to the device. Therefore, after attaching the lead storage battery to the device, it is necessary to remove these supports. After carrying the heavy lead storage battery, the knot 8 was tightly tied, and it took a lot of time to untie it. Therefore, in order to perform this operation in a short time, the strap 6 for the carrying hand may be cut, which is not preferable from the viewpoint of saving resources.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to an object of the present invention is to provide a support structure which can be easily attached to and detached from a lead storage battery in a short time.

[0005]

In order to solve the above-mentioned problems, a first invention uses a strap for carrying a lead-acid battery, and a mounting hole for attaching the strap for carrying is provided with a lid. In the lead-acid battery holder structure formed so as to penetrate the upper surface portion and the side surface portion of the lead-acid battery, the strap for the handle is formed by a string portion and a substantially rectangular parallelepiped node formed at both ends thereof. The node has a node height that is greater than the node height, and has a substantially rectangular upper opening on the top surface of the lid, and a substantially convex side opening on the side surface. The mounting structure of the strap for the carrying hand is formed,
The dimension in the short side direction of the upper opening is larger than the length of the node and smaller than the height of the node, and the dimension of the side opening in the bottom direction and the height is smaller than the height of the node. It is characterized by being larger than the size of the height.

[0006] A second invention is characterized in that the string for the carrying hand is formed by integrating the knot portion and the string portion by insert molding, and the third invention is characterized in that the string for the carrying hand is provided. The string is characterized in that the side of the node is larger than the height of the node.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS.

[0010] The strap 6 of the present invention is formed of a string portion 8 made of polypropylene resin, and a substantially rectangular parallelepiped node 7 made of polypropylene resin formed at both ends thereof (FIG. 3). . In addition, the string 6 for a hand is prepared integrally by previously fixing the string portion 8 to a mold, pouring a polypropylene resin, and insert-molding. As shown in FIG. 3, the dimensions of the substantially rectangular parallelepiped nodes were manufactured by changing the dimensions in the following order: node vertical 7a <node height 7b <node horizontal 7c.

On the other hand, the battery case 1 and the lid 2 of the lead-acid battery are both made of polypropylene resin.
A mounting hole 3a is provided as shown in FIG. Each of the mounting holes 3a is formed so as to penetrate the upper surface portion and the side surface portion of the lid 2, and a strap 6 for a hand to be described later is passed through the penetrating portion. As shown in FIG.
The upper opening 5 of the portion formed on the upper surface of the cover 2 has a substantially rectangular shape, and the side opening 4 of the portion formed on the side surface of the lid 2 has a substantially convex shape. The dimension of the upper opening hole 5 formed on the upper surface of the lid in the short side direction 5a is larger than the dimension of the node vertical 7a and smaller than the dimension of the node height 7c. did. The side opening 4 has a dimension in the bottom direction 4b and a dimension in the height direction 4a larger than the dimension of the node height 7c.

The node 7 having a substantially rectangular parallelepiped shape is connected to the node vertical
With the surface formed by 7a and the side of the node 7b as the bottom surface, insert through the upper opening 5 (FIG. 1- (a)), pull out the node 7 from the side opening 4, and rotate 90 degrees. (Figure 1
(B)), and reinserted into the side opening 4 with the surface formed by the joint side 7b and the joint height 7c as the bottom surface (FIG. 1).
(C)). Therefore, as described above, the node 7 does not rotate in the side opening 4 in the state of FIG. 1C due to the dimensional relationship between the node 7 and the side opening 4.

Further, the upper opening hole 5 having a substantially rectangular shape is provided.
Since the dimension of the short side direction 5a is shorter than the dimension of the joint height 7c, even if the lead-acid battery is carried with the strap 6 for the carrying hand, the joint 6 of the strap 6 for the carrying Never get out of the way. In addition, by increasing the dimension of the joint side 7c from the dimension of the joint height 7b to increase the area of the welded portion,
The adhesion strength between 7 and the lace 8 can be improved,
It is possible to make it difficult for the string portion 8 to be detached from 7. on the other hand,
After attaching to a device using a lead-acid battery, the hand strap 6 can be easily removed from the attachment hole 3a in the reverse procedure described above.

By using the present invention, a strap for a hand
6 can be easily installed and removed in a short time. Therefore, when the present invention is used, as described above, it is not necessary to cut the strap for removing the strap 6 and the strap for strap 6 can be used over and over again. This is preferable from the viewpoint of saving.

[0013]

As described above, the use of the strap structure of the present invention facilitates the attachment and detachment of the strap for the strap, and can be used repeatedly over and over, thus saving resources. It is preferable from a viewpoint.
