  Next, the operation of the automobile transport vehicle 10 and the transported vehicle fixing device 16 will be described.

  First, an operation when the transported vehicle 12 is fixed to the loading platform 14 will be described.

  First, the operator places the movable base 28 in the vicinity of a desired mounting position, and the lower end of the shaft portion 32A of the fitting locking portion 32 of the movable base 28 is connected to the lip groove 18 in the upper surface portion 20 of the fixed rail 26. The movable base 28 is pressed against the fixed rail 26 while being brought into contact with the narrow width portion 24 and retracting the shaft portion 32A against the urging force of the urging portion 34.

  Accordingly, the flange locking portion 36 of the movable base 28 is inserted through the wide portion 22 of the lip groove 18 of the fixed rail 26, and the flange portion 36 </ b> B enters the lip groove 18 below the upper surface portion 20 of the fixed rail 26.

  Next, the operator moves the movable base 28 toward a desired mounting position in the longitudinal direction (vehicle longitudinal direction) of the fixed rail 26 while pressing the movable base 28 against the fixed rail 26 side. The main portion 36 </ b> A of the flange locking portion 36 transitions from the wide portion 22 of the lip groove 18 of the fixed rail 26 to the narrow portion 24. Note that the flange locking portions 36 on both sides in the vehicle front-rear direction of one fitting locking portion 32 of the two fitting locking portions 32 are attached to the long holes 30F of the bottom plate portion 30A of the base portion 30. Even if there is an attachment error with respect to the distance between the pair of fixed rails 26 in the vehicle width direction, the error can be absorbed by sliding in the vehicle width direction and can be shifted from the wide width portion 22 to the narrow width portion 24 of the lip groove 18. When the shaft portion 32A of the fitting locking portion 32 moves about half of the pitch of the wide width portion 22 of the lip groove 18 while sliding with the upper surface portion 20 of the fixed rail 26, the shaft portion 32A is moved by the urging force of the urging portion 34. It protrudes downward and fits into the wide portion 22 of the lip groove 18, and the lower end contacts the bottom surface of the lip groove 18. In this state, the flange portion 36 </ b> B of the flange locking portion 36 is positioned below the narrow portion 24 of the lip groove 18 in the upper surface portion 20 of the fixed rail 26.

  Here, when the operator removes his / her hand from the movable base 28, the flange portion of the flange locking portion 36 is caused by the reaction force of contact with which the lower end of the shaft portion 32 </ b> A of the fitting locking portion 32 contacts the bottom surface of the lip groove 18. 36B abuts on both sides of the narrow portion 24 of the lip groove 18 on the upper surface portion 20 of the fixed rail 26 from below.

  Since the shaft portion 32A of the fitting locking portion 32 is fitted to the wide portion 22 of the lip groove 18, the movable base 28 is restricted from moving in the horizontal direction. Further, since the lower end of the shaft portion 32A comes into contact with the bottom surface of the lip groove 18 and the flange portion 36B of the flange locking portion 36 comes into contact with the upper surface portion 20 of the fixed rail 26 from below, the movable base 28 can move in the vertical direction. Be regulated. Further, since the shaft portion 32 </ b> A and the flange portion 36 </ b> B of the flange locking portion 36 are urged by the urging portion 34 and abut against the fixed rail 26, the movable base 28 does not rattle with respect to the fixed rail 26. Thus, the movable base 28 can be reliably fixed to the fixed rail 26 by a simple operation without using a tool or the like.

  When fixing two wheels 12 </ b> A in the vehicle width direction for one transported vehicle 12, the above operation is repeated twice, and the two movable bases 28 are attached to the loading platform 14 via the four fixed rails 26. Fix it.

  Next, the transported vehicle 12 is moved to a position where the wheel 12 </ b> A abuts against the wheel stopper member 40 by self-propelling, and the wire 42 is wound around the wheel 12 </ b> A of the transported vehicle 12 and the wire 42 using the ratchet mechanism 44. BDSM. When fixing two wheels 12A in the vehicle width direction for one transported vehicle 12, the wire 42 is wound only on the wheel 12A that contacts the wheel stopper member 40, but the wheel that contacts the wheel stopper member 40. A common wire 42 may be wrapped around the front or rear wheel 12A together with 12A to fix the four wheels. Thereby, the work of fixing the transported vehicle 12 to the loading platform 14 is completed.

  Next, an operation when the transported vehicle 12 is released from the loading platform 14 will be described.

  First, the operator uses the ratchet mechanism 44 to loosen the wire 42, removes the wire 42 from the wheel 12 </ b> A, and moves the transported vehicle 12 in a direction in which the wheel 12 </ b> A is separated from the wheel stopper member 40 by self-propelling.

  Next, the operator inserts his hands on both sides of the base 30 of the movable base 28, pulls up the two operation portions 38B of the release member 38, and biases the shaft portion 32A of the fitting locking portion 32. It is raised against the urging force of 34 and pulled up above the upper surface portion 20 of the fixed rail 26.

  In this state, the operator moves the movable base 28 in the longitudinal direction of the fixed rail 26 (the vehicle longitudinal direction) by about half the pitch of the wide portion 22 of the lip groove 18. As a result, the flange locking portion 36 moves to the portion of the wide width portion 22 of the lip groove 18 of the fixed rail 26.

  Here, when the movable base 28 is lifted upward, the flange portion 36 </ b> B of the flange locking portion 36 passes through the wide portion 22 of the lip groove 18, and the movable base 28 is removed from the fixed rail 26. Thereby, the operation of releasing the transported vehicle 12 from the loading platform 14 is completed.

  In this way, the movable base 28 can be attached to the fixed rail 26 with a simple operation, and the movable base 28 can be detached from the fixed rail 26 with a simple operation, so that the vehicle carrier 10 has a high work efficiency.

  Furthermore, since the movable base 28 is securely fixed to the fixed rail 26 and the transported vehicle 12 does not rattle on the loading platform 14, the automobile transport vehicle 10 is highly reliable.

  Further, since a pair of flange locking portions 36 are provided on both sides (in the vehicle front-rear direction) of each fitting locking portion 32, the stability of fixing the movable base 28 to the fixed rail 26 is enhanced.

  Further, since a pair of fixed rails 26 are installed for one movable base 28 and the movable base 28 is installed on the two fixed rails 26, the stable fixing of the movable base 28 to the fixed rail 26 is also possible in this respect. Sexuality is enhanced.

  In the present embodiment, the transported vehicle 12 is a four-wheeled vehicle, but the present invention can also be applied to a case where a motorcycle is fixed.

  When the load acting on the movable base 28 is small as in the case of fixing a motorcycle, only one fixed rail 26 may be installed for one movable base 28. Moreover, you may provide a flange latching | locking part only in the one side of each fitting latching | locking part (vehicle front-back direction).

  In the present embodiment, a wire is used as a string-like member wound around the wheel 12, but a string-like member made of another material such as a synthetic fiber may be used.

  In the present embodiment, the wheel stop member 40 and the ratchet mechanism 44 are attached to the movable base 28, but the members attached to the movable base may be appropriately changed according to the purpose. For example, only one of the wheel stopper member 40 and the ratchet mechanism 44 may be attached to the movable base 28.

  The present invention can be used for an automobile carrier or the like.
