Hinged door
A door main body includes a through hole formed on an end surface located at an end of the door main body in a rotation axis direction of rotation of the door main body, a cable or a hose being inserted through the through hole. A door frame portion includes: a frame opening portion which is formed on a surface opposed to the through hole and has a shape corresponding to a movement trajectory of the through hole when the door main body is opened or closed; and a slide supporting member supporting the cable or the hose extending through the frame opening portion while sliding relative to the frame opening portion.
1. A hinged door comprising:
a door frame portion;
a door main body arranged inside the door frame portion; and
an attaching member by which the door main body is rotatably attached to the door frame portion, wherein:
a cable or a hose extends between the door frame portion and the door main body;
the door main body includes a first through hole formed on an end surface located at an end of the door main body in a rotation axis direction of rotation of the door main body, the cable or the hose being inserted through the first through hole; and
the door frame portion includes
a second through hole which is formed on a surface of the door frame portion, the surface being located opposed to the first through hole, the second through hole having a shape corresponding to a movement trajectory of the first through hole when the door main body is opened or closed, and
a slide supporting member supporting the cable or the hose extending through the second through hole while sliding relative to the second through hole.
2. The hinged door according to claim 1 , wherein:
the slide supporting member includes a supporting portion supporting the cable or the hose and a covering portion adjacent to the supporting portion and extending in a direction in which the slide supporting member slides; and
the covering portion covers at least a part of the second through hole.
3. The hinged door according to claim 2 , wherein:
a maximum rotation angle of the door main body is not more than 100°;
the first through hole is located at a hanging side of the door main body; and
the slide supporting member slides linearly.
4. The hinged door according to claim 3 , wherein:
the hinged door is provided at an end surface of a railcar; and
the door main body opens toward a car inner side.
5. The hinged door according to claim 1 , wherein each of the door main body and the door frame portion is formed in a quadrangular shape.
