Abstract

A tire support device includes: a first rim support portion; a second rim support portion which is provided so as to oppose the first rim support portion; a frame which includes a guide which movably guides the second rim support portion in a direction approaching or separating from the first rim support portion; a transport portion which is movably attached along the guide; a drive portion which moves the transport portion along the guide; an engagement mechanism which can engage with the frame at a retreat position at which the second rim support portion is separated from the first rim support portion; and a supported portion which integrally supports the second rim support portion and the transport portion in a movable manner along the guide in a state where engagement with the engagement mechanism is released.

First claim

The invention claimed is:

1. A tire support device, comprising:
a first rim support portion which supports a first rim mounted on a tire;
a second rim support portion which is provided so as to oppose the first rim support portion and supports a second rim mounted on the tire;
a frame which includes a guide which movably guides the second rim support portion in a direction approaching the first rim support portion and in a direction separating from the first rim support portion, the second rim support portion being attached to the guide;
a transport portion which is attached to the guide to move along the guide, and performs at least one of extraction of the tire supported by the first rim support portion and attachment of the tire to the first rim support portion;
a drive portion which moves the transport portion along the guide;
an engagement mechanism which can engage the second rim support portion with the frame at a retreat position at which the second rim support portion is separated from the first rim support portion;
a supported portion which integrally supports the second rim support portion and the transport portion in a movable manner by the drive portion along the guide in a state where engagement with the engagement mechanism is released; and
a connection mechanism which is configured to mechanically connect the second rim support portion and the transport portion in a vertical direction in a state where the second rim support portion and the transport portion are stacked in the vertical direction so that the second rim support portion and the transport portion are integrated in a state where engagement with the engagement mechanism is released,
wherein the connection mechanism is configured to move the second rim support portion and the transport portion at a time in the vertical direction in a state where engagement with the engagement mechanism is released,
the connection mechanism comprises:
a movement member which is provided on one of the second rim support portion and the transport portion, the movement member is configured to be moved by an engagement operation and a disengagement operation of the engagement mechanism; and
a fixing member which is provided on the other of the second rim support portion and the transport portion,
wherein the movement member comprises a through-hole extending in a horizontal direction,
the through-hole comprises a first hole portion, and a second hole portion which is continuous with the first hole portion and which is provided further from the guide than the first hole portion, wherein a width of the second hole portion is larger than that of the first hole portion,
the fixing member comprises a first shaft portion protruding toward the one of the second rim support portion and the transport portion, and a second shaft portion provided on a tip of the first shaft portion,
a width of the first shaft portion is smaller than that of the first hole portion,
a width of the second shaft portion is larger than that of the first hole portion and is smaller than that of the second hole portion, and
the fixing member and the movement member are configured to engage with each other by arranging the first shaft portion in the first hole portion, and to disengage from each other by arranging the first shaft portion in the second hole portion via switching by the movement of the movement member.

2. The tire support device according to claim 1 , wherein the engagement mechanism includes:
an engagement member which is provided on one of the second rim support portion and the frame, and can advance and retreat in a direction in which the second rim support portion and the frame are connected to each other;
an engagement portion which is provided on the other of the second rim support portion and the frame and engages with the engagement member which is in an advanced position; and
an advancing-retreating portion which advances and retreats the engagement member.

3. The tire support device according to claim 2 , wherein a key portion which protrudes downward is formed on the engagement member, and
wherein a key engagement portion, which meshes with the key portion in a state where the engagement member engages with the engagement portion, is formed on the engagement portion.

4. A tire cooling system, comprising: a tire support device according to claim 1 ; and
a fluid supply portion which can supply a fluid injected into the tire in which the first rim and the second rim are mounted.

5. A tire support device, comprising:
a first rim support portion which supports a first rim mounted on a tire;
a second rim support portion which is provided so as to oppose the first rim support portion and supports a second rim mounted on the tire;
a frame which includes a guide which movably guides the second rim support portion in a direction approaching the first rim support portion and in a direction separating from the first rim support portion, the second rim support portion being attached to the guide;
a transport portion which is attached to the guide to move along the guide, and performs at least one of extraction of the tire supported by the first rim support portion and attachment of the tire to the first rim support portion;
a drive portion which moves the transport portion along the guide;
an engagement mechanism which can engage the second rim support portion with the frame at a retreat position at which the second rim support portion is separated from the first rim support portion;
a supported portion which integrally supports the second rim support portion and the transport portion in a movable manner by the drive portion along the guide in a state where engagement with the engagement mechanism is released; and
a connection mechanism configured to:
mechanically connect the second rim support portion and the transport portion in a vertical direction in a state where the second rim support portion and the transport portion are stacked in the vertical direction so that the second rim support portion and the transport portion are integrated in a state where engagement with the engagement mechanism is released, and
move the second rim support portion and the transport portion at a time in the vertical direction in a state where engagement with the engagement mechanism is released,
the connection mechanism comprises:
a movement member which is provided on one of the second rim support portion and the transport portion, and is moved by an engagement operation and a disengagement operation of the engagement mechanism; and
a fixing member provided on the other of the second rim support portion and the transport portion,
wherein the fixing member protrudes toward the one of the second rim support portion and the transport portion, the fixing member comprises a hole passing through the fixing member in a horizontal direction, and
the fixing member and the movement member are configured to engage with each other by inserting the movement member into the hole and to disengage from each other by separating the movement member from the hole via switching by the movement of the movement member.
