Abstract

The opening and closing mechanism for opening and closing bodies has a first opening and closing body, a second opening and closing body, a first support member, a second support member, a first and second guide member, wherein a first and a second guide member intermediate portion are disposed to have an overlapping region, in the overlapping region, one of the first guide member intermediate portion and the second guide member intermediate portion is arranged, with respect to the other of the first guide member intermediate portion and the second guide member intermediate portion, in a direction to which a load is applied, and each of the first to fourth connecting portions has a rolling element provided at a side so as to apply a load toward toe guide members.

First claim

What is claimed is:

1. An opening and closing mechanism for opening and closing bodies comprising;
an opened member having a first opening and a second opening;
a first opening and closing body being movable between an opened position where the first opening is opened and a closed position where the first opening is closed:
a second opening and closing body being movable between an opened position where the second opening is opened and a closed position where the second opening is closed:
a first support member for supporting the first opening and closing body, the first support member mounted to the first opening and closing body:
a second support member for supporting the second opening and closing body, the second support member mounted to the second opening and closing body: and
guide members provided to the opened member and guiding the first opening and closing body and the second opening and closing body via the first support member and the second support member, respectively, such that each of the first opening and closing body and the second opening and closing body is reciprocally movable between the opened position and the closed position, wherein
the guide members have a first guide member and a second guide member, each of the first guide member and the second guide member extending from the first opening side to the second opening side of the opened member,
the first support member has a first connecting portion connected to the first guide member so as to be movable relative the first guide member and a second connecting portion connected to the second guide member so as to be movable relative to the second guide member,
the second support member has a third connecting portion connected to the first guide member so as to be movable relative to the first guide member and a fourth connecting portion connected to the second guide member so as to be movable relative to the second guide member,
the first guide member has
a first closed position guide portion guiding the first connecting portion so that the first opening and closing body moves to the closed position where the first opening is closed,
a second closed position guide portion guiding the third connecting portion so that the second opening and closing body moves to the closed position where the second opening is closed, and
a first guide member intermediate portion connected to the first closed position guide portion and the second closed position guide portion, the first connecting portion and the third connecting portion being movable on the first guide member intermediate portion,

the second guide member has
a third closed position guide portion guiding the second connecting portion so that the first opening and closing body moves to the closed position where the first opening is closed,
a fourth closed position guide portion guiding the fourth connecting portion so that the second opening and closing body moves to the closed position where the second opening is closed, and
a second guide member intermediate portion connected to the third closed position guide portion and the fourth closed position guide portion, the second connecting portion and the fourth connecting portion being movable on the second guide member intermediate portion,
the first guide member intermediate portion and the second guide member intermediate portion are disposed in parallel with each other and are disposed to have an overlapping region, in the overlapping region, one of the first guide member intermediate portion and the second guide member intermediate portion is arranged, with respect to the other of the first guide member intermediate portion and the second guide member intermediate portion, in a direction to which a load from the first opening and closing body and the second opening and closing body via each of the connecting portions is applied,

each of the first connecting portion, the second connecting portion, the third connecting portion and the fourth connecting portion has a rolling element provided at a side so as to apply a load toward the guide members, and
the first support member and the second support member are mounted at positions where, when one of the first opening and closing body and the second opening and closing body is located at the closed position, the other of the first opening and closing body and the second opening and closing body is movable in a double-sliding manner.

2. The opening and closing mechanism for opening and closing bodies of claim 1 ,
wherein the first support member has
a first mounting portion to be mounted to the first opening and closing body, and
a first extending portion extending from the first connecting portion in a direction in which the first mounting portion is away from the first guide member when the first opening and closing body is located at the closed position, and

the second support member has
a second mounting portion to be mounted to the second opening and closing body, and
a fourth extending portion interposed between the second mounting portion and the fourth connecting portion and provided so as to extend across the first extending portion in a moving direction of the second opening and closing body when the second opening and closing body is located at the opened position.

3. The opening and closing mechanism for opening and closing bodies of claim 1 ,
wherein the first connecting portion and the second connecting portion are mounted over the first opening and closing body,
the third connecting portion and the fourth connecting portion are mounted over the second opening and closing body, and
the first guide member and the second guide member are disposed being overlapped each other in an up-and-down direction.

4. The opening and closing mechanism for opening and closing bodies of claim 1 ,
wherein each of the first connecting portion, the second connecting portion, the third connecting portion and the fourth connecting portion comprises a radial roller receiving a load in a vertical direction and a thrust roller receiving a load in a horizontal direction.

5. The opening and closing mechanism for opening and closing bodies of claim 1 ,
wherein the opened member is provided with third guide member at an opposite side of the opened member to a side at which the first guide member and the second guide member are provided,
the first opening and closing body is provided with a third support member having a fifth connecting portion connected the third guide member, the third support member being mounted at an opposite position to a position at which the first support member is mounted,
the second opening and closing body is provided with a fourth support member having a sixth connecting portion connected to the third guide member, the fourth support member being mounted at an opposite position to a position at which the second support member is mounted, and
the third guide member is provided at a position where the fifth connecting portion and the sixth connecting portion press the third guide member.
