Abstract

A conveying apparatus includes an outer casing for disposing the conveying apparatus on a traveling structure, a storage case that is disposed inside the outer casing and that allows a stored article to be placed therein and removed therefrom from above, a plurality of stretchable elastic members that are spaced apart from each other in a crosswise direction and each of which includes a bridging portion that bridges between front and rear ends of the outer casing in a traveling direction of the traveling structure, and a plurality of suspension devices that are spaced apart from each other at least in a fore-aft direction and each of which includes an upper end assuming a supported portion that is supported slidably on the elastic member and a lower end assuming a supporting portion that supports the storage case.

First claim

The invention claimed is:

1. A conveying apparatus, comprising:
an outer casing for disposing the conveying apparatus on a traveling structure;
a storage case disposed inside the outer casing, the storage case allowing a stored article to be placed therein and removed therefrom from above;
a plurality of stretchable elastic members spaced apart from each other in a crosswise direction, each of the elastic members including a bridging portion that bridges between front and rear ends of the outer casing in a traveling direction of the traveling structure; and
a plurality of suspension devices spaced apart from each other at least in a fore-aft direction, each of the suspension devices including an upper end assuming a supported portion that is supported slidably on the elastic member and a lower end assuming a supporting portion that supports the storage case, wherein
the suspension devices are supported by the elastic members pivotally rockably about the supported portions,
the storage case is supported by the suspension devices pivotally rockably about the supporting portions, and
the storage case is suspended on the elastic members by the suspension devices under a condition in which a gap is available between the storage case and the outer casing.

2. The conveying apparatus according to claim 1 , wherein
the elastic members are disposed in parallel with each other.

3. The conveying apparatus according to claim 1 or 2 , wherein
the elastic members comprise two elastic members, and
the bridging portions of the two elastic members are disposed at positions immediately above both ends in the crosswise direction, respectively, of the storage case.

4. The conveying apparatus according to claim 1 , wherein
the suspension devices each include a connecting portion that connects between the supported portion and the supporting portion, and
the connecting portions are disposed between the storage case and the outer casing.

5. The conveying apparatus according to claim 1 , further comprising:
a tension adjustment structure that adjusts tension in the elastic members.

6. The conveying apparatus according to claim 1 , wherein
each of both ends of each of the elastic members in a direction in which the elastic member is stretched assumes an attached portion to be attached on the traveling structure.
