Abstract

A first constituent member configured such that a plurality of panels overlaps and a second constituent member configured such that a plurality of panels overlaps are included, in which a first link member that can be expanded and contracted is connected to the first constituent member, a second link member that can be expanded and contracted is connected to the second constituent member, each of the constituent members can be expanded and contracted by expansion and contraction of each of the link members, the first constituent member and the second constituent member can relatively be rotated around rotation axes and also can removably be connected, the first link member and the second link member are connected to both ends of connecting link arm members via a free joint respectively, and the first link member and the second link member can be separated from each other.

First claim

The invention claimed is:

1. An expansion device of panels comprising:
a first constituent member constructed by a plurality of panels; and
a second constituent member constructed by a plurality of panels that are different from the plurality of panels constructing the first constituent member, wherein
adjacent panels of the first constituent member partly overlap each other, a first link member that can be expanded and contracted is connected to the first constituent member, and the first constituent member can be expanded and contracted by expansion and contraction of the first link member,
adjacent panels of the second constituent member partly overlap each other, a second link member that can be expanded and contracted is connected to the second constituent member, and the second constituent member can be expanded and contracted by expansion and contraction of the second link member,
the first constituent member and the second constituent member can relatively be rotated around rotation axes provided in the expansion and contraction direction of the link members and also can removably be connected,
the first link member and the second link member are connected to both ends of connecting link arm members via a free joint respectively, and
the first link member and the second link member can be separated from each other.

2. The expansion device of panels according to claim 1 , wherein
the first link member includes a first main arm member and a second main arm member provided in parallel and provides a plurality of connecting arm members provided in parallel by rotatably connecting one end of each of the connecting arm members to the second main arm member and the other end thereof to the first main arm member,
the second link member includes a third main arm member and a fourth main arm member provided in parallel and provides a plurality of connecting arm members provided in parallel by rotatably connecting one end of each of the connecting arm members to the fourth main arm member and the other end thereof to the third main arm member,
a plurality of the connecting link arm members is provided,
a main arm member in the first link member and a main arm member in the second link member are connected by one of the connecting link arm members,
a connecting arm member in the first link member and a connecting arm member in the second link member are connected by the other of the connecting link arm members,
panels provided at both ends of the constituent members are rotatably connected to any main arm members, and
a panel provided anywhere other than at both ends of the constituent members or one of the connecting arm members is provided with a rotation axis, to which the other is loosely fitted and connected.

3. The expansion device of panels according to claim 1 , wherein the expansion device of panels is provided between bodies of rolling stock.
