Abstract

A transport structure ( 1 ) for a lead-acid battery ( 10 ) includes: a packing box ( 20 ) in which a lead-acid battery ( 10 ) is packed, in which an upper wall portion ( 23 ) is formed by two flaps ( 24 ) extending from two first side wall portions ( 21 ) facing each other of the packing box ( 20 ), and in which a distal end portion ( 26 ) of at least one of the flaps ( 24 ) is bent and inserted into the packing box ( 20 ); and an upper buffer body ( 42 A) disposed outside the upper wall portion ( 23 ), the upper buffer body ( 42 A) including an upper wall portion ( 51 ) facing the upper wall portion ( 23 ).

First claim

The invention claimed is:

1. A transport structure for a lead-acid battery comprising:
a packing box in which a lead-acid battery is packed, in which a second wall portion is formed by two flaps extending from two first wall portions facing each other of the packing box, and in which a distal end portion of at least one of the two flaps is bent and inserted into the packing box; and
a buffer body disposed outside the second wall portion, the buffer body including a third wall portion facing the second wall portion,
wherein the third wall portion has a projecting portion projecting toward the second wall portion, and at least a part of the distal end portion of the at least one of the two flaps overlaps the projecting portion when viewed from a direction orthogonal to a wall surface of the third wall portion, and
a terminal is provided on a surface of the lead-acid battery facing the second wall portion, and the terminal and the projecting portion do not overlap when viewed from the direction orthogonal to the wall surface of the third wall portion.

2. The transport structure for a lead-acid battery according to claim 1 , wherein when the packing box falls in a posture in which a surface of the lead-acid battery facing the second wall portion faces downward, the distal end portion of the at least one of the two flaps is sandwiched between the lead-acid battery and the third wall portion and crushed, so that an impact of the falling is buffered.

3. The transport structure for a lead-acid battery according to claim 1 , wherein the entire distal end portion of the at least one of the two flaps overlaps the projecting portion as viewed from the direction orthogonal to the wall surface of the third wall portion.

4. The transport structure for a lead-acid battery according to claim 1 , wherein a surface side of the projecting portion on a side opposite to a surface facing the second wall portion is hollow.

5. The transport structure for a lead-acid battery according to claim 1 ,
wherein the terminal is provided on any one side in a short-side direction with a center in the short-side direction of the lead-acid battery as a reference or provided on any one side in a long-side direction with a center in the long-side direction of the lead-acid battery as a reference when viewed from the direction orthogonal to the wall surface of the third wall portion, and
wherein even when the buffer body is rotated by 180 degrees around a straight line perpendicular to the wall surface of the third wall portion and disposed, the terminal and the projecting portion do not overlap when viewed from the direction orthogonal to the wall surface of the third wall portion.

6. The transport structure for a lead-acid battery according to claim 1 , wherein a width of the distal end portion of the at least one of the two flaps in the direction orthogonal to the wall surface of the third wall portion is wider than a width of the terminal in the direction orthogonal to the wall surface of the third wall portion.

7. The transport structure for a lead-acid battery according to claim 1 , further comprising:
a fourth wall portion having a frame shape that is continuous with a peripheral edge portion of the third wall portion and surrounds the packing box; and
a fifth wall portion having a frame shape that is connected to the fourth wall portion and surrounds the fourth wall portion,
wherein a space is provided between the fourth wall portion and the fifth wall portion.

8. The transport structure for a lead-acid battery according to claim 7 , wherein the third wall portion and the fourth wall portion are recessed so as to be separated from a corner portion of the packing box.

9. The transport structure for a lead-acid battery according to claim 1 , wherein the buffer body is made of pulp mold.
