Abstract

An autonomous traveling unit is provided with a pair of toggle mechanisms. The toggle mechanisms respectively have displaceable bodies provided with cam followers. A workpiece loading unit is provided with a member in an X shape to be clamped. The cam followers are respectively advanced to a pair of opposing corners (a first crossing portion and a second crossing portion) of the member to be clamped. When advancing to the pair of opposing corners, the cam followers are respectively brought into abutment on the member to be clamped, whereby the workpiece loading unit is restrained on the autonomous traveling unit.

First claim

What is claimed is:

1. A transport vehicle having an autonomous traveling unit and a workpiece loading unit detachably supported over the autonomous traveling unit, the transport vehicle comprising:
at least one pair of toggle mechanisms provided on the autonomous traveling unit and including displaceable bodies that are synchronously displaceable;
cam followers provided on the displaceable bodies; and
a member to be clamped on the workpiece loading unit and configured to allow the cam followers to advance to the member to be clamped;
wherein:
the member to be clamped is formed in an X-shape having two pairs of opposing corners;
the cam followers respectively advance to one pair of opposing corners to abut on the member to be clamped at opposing positions over the clamped member, so that the workpiece loading unit is restrained on the autonomous traveling unit; and
the cam followers are respectively retracted from the one pair of opposing corners, so that the workpiece loading unit is released from restraint on the autonomous traveling unit.

2. The transport vehicle according to claim 1 , wherein:
the displaceable bodies each have three cam followers; and
the three cam followers are arranged at vertices of a triangle with one of the cam followers advanced to the opposing corner.

3. The transport vehicle according to claim 2 , wherein:
when the one of the cam followers advanced to the opposing corner is brought into abutment on the clamped member, the remaining two cam followers are also brought into abutment on the clamped member.

4. The transport vehicle according to claim 2 , wherein:
the displaceable bodies are each formed in an approximately triangle shape.

5. The transport vehicle according to claim 1 , wherein:
the displaceable bodies are displaceable to come close to or away from each other in a horizontal direction.

6. The transport vehicle according to claim 1 , further comprising:
guide members that guide the displaceable bodies when the displaceable bodies are displaced.
