Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a vehicle transport device for moving a vehicle that cannot travel on its own by towing it.

B. Prior Art Conventionally, a vehicle transport device for moving a vehicle that is not self-propelled has a fixed wheel stop that projects horizontally to the left and right, and a fixed wheel stop for the fixed wheel stop, as described in, for example, Japanese Utility Model Application No. 61-34595. There was a device that used a tire holder consisting of a movable wheel chock that could be fixed in a position parallel to the wheel chock to hold the tire between both wheel chock and lift and tow the vehicle in that state.

C. Problems to be Solved by the Invention The conventional device described above first places the movable wheel chock in a forward position relative to the entry direction and enters under the vehicle.
When the fixed wheel chock contacts the outer circumference of the tire, the approach must be temporarily stopped, then the movable wheel chock must be rotated and fixed until it is parallel to the fixed wheel chock, and then the tire clamping device must be raised. Its operation is complicated, and it requires a rotating mechanism for the movable wheel stop and its fixing device, which increases costs.
It had the disadvantage of being prone to malfunction.

D. Means for Solving the Problem The present invention is a vehicle transport device that can easily carry out tire clamping work without worrying about breakdowns. death,
A symmetrical mounting bar is attached to the central tip of the lift plate so that it can rotate horizontally using the center as a fulcrum, and U-shaped tire holders are attached to both ends of the mounting bar with the opening side facing outward. The purpose is to pivotally support the front corner portion in the state where the tip is held, and to apply an inward biasing force to the tip side.

E. Embodiment In FIG. 1 showing a vehicle transport device according to the present invention, a fork 1 consisting of two elevating plates 2, 2 projecting forward in parallel is mounted on the front side of a base 1a equipped with wheels. It is a self-propelled trolley equipped with a case 1b having a built-in battery and a motor at the rear, and a handle 1 protruding diagonally upward at the rear end.
It can be freely moved forward, backward, left and right by operating c. Between the elevating plates 2, 2, the elevating plate 2,
A connecting body 2a is attached integrally with the connecting body 2, and a horizontally long mounting bar 3 is attached to the central tip of the fork via the connecting body 2a so that the horizontally long mounting bar 3 can be rotated horizontally. It is being Further, U-shaped tire holders 4, 4 are attached to both ends of the mounting bar 3, with the opening side facing outward and the front corner being pivotally supported, and the other corner being pivotally supported. A coil spring 5 is stretched between the parts. Thereby, the tire holder 4,
4 has its front sides pulled toward the center so that the open side faces diagonally forward left and right in an inverted figure-eight shape. In addition, the tire clamping tool 4 has a wheel chock 4 on the tip side.
a is shorter than the wheel stopper 4b on the front side, and the wheel stopper 4b on the rear end side is curved outward in an arched shape.

To explain how to use it, by operating the handle 1c, the self-propelled trolley 1 is brought close to the vehicle from directly in front (straight behind), and both wheel holders 4, 4 are moved into the underside of the vehicle. Then, the front wheel chock 4b comes into contact with the outer periphery of the tire 5, and the tire holder 4 is rotated outward. When both wheel chock 4a and 4b become perpendicular to the direction of approach, the approach is stopped and the elevating plate is moved. 2, 2 is raised, the tire 6 is held in a pinched state by the wheel chocks 4a, 4b. If a stopper mechanism is provided that locks the wheel chock 4b when it becomes perpendicular to the direction of approach, the timing to stop the approach can be known by the locking operation, and the tire holding operation during towing becomes stable. Once the tire 6 is held and lifted, the vehicle M can be towed by operating the traveling trolley.

As described above, the vehicle carrying device of the present invention is extremely easy to operate because it holds the tire properly by simply entering the tire holder into the underside of the vehicle and lifting the elevating plate. In addition, the tire holder is attached to both ends of a rotatable mounting bar, and the angle can be changed with respect to the lifting plate, so if there is not enough space for the cart on the entry side,
It is also possible to enter from the diagonal side by rotating the attachment bar 3 as shown in the fourth figure. Furthermore, the front wheel chock is made short to make it easier for the tire to enter, and the front wheel chock, which comes into contact with the tire and is pressed when the tire enters, is curved in an arched shape, which reduces the tire's gripping action. can be done smoothly.

In the above embodiment, the mounting bar is straight in the left and right directions, but it may be in a V-shape as shown in FIG. 5, for example, as long as it is symmetrical. Also, explanations of the drive mechanism of the trolley and the elevating mechanism of the elevating plate have been omitted, but
These mechanisms may be determined as appropriate within the range that can achieve the purpose of the present invention.

F. Effects According to the vehicle transport device of the present invention, the tire holding operation can be performed by simply inserting the tire holder into the lower part of the vehicle. There is no need to install it, making it simple, easy to handle, and there is no need to worry about malfunctions or breakdowns.
