BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle towing device for towing a vehicle, such as an automobile, that has broken down due to an accident, with the left and right wheels mounted and held separately.

0002

[Prior Art] Conventionally, this type of vehicle traction device has
For example, there is one disclosed in Japanese Utility Model Publication No. 52-9123. In this system, a tow bar that extends forward is integrally installed in the center of the front of the framed chassis, and wheel holders are installed on both sides at a distance about the width of the car, and a pair of wheels are mounted on the shafts inside both wheel holders. It consists of the following configuration. and,
When a vehicle such as an automobile that has been involved in an accident is towed, both the left and right wheels, including those that are unable to rotate due to the accident, are placed and fixed on the wheel holders and the tow bar is pulled.

However, a traction device constructed in this manner necessarily requires a width comparable to that of a general automobile, resulting in an increase in size and weight. Therefore, not only does it require a large amount of force to move, but it is also difficult to operate, especially for people with weak strength. Furthermore, since it cannot be disassembled, it requires a large space for storage, and there are also problems in that it is expensive to manufacture. In particular, since the wheels are mounted at a narrower position than the wheel holders on both sides, i.e., narrower than the wheels of a general automobile, a pair of gangplanks are used that are slanted between the truck bed and the road surface. When placing an accident vehicle on top of a truck, it has a fatal drawback in that the wheels of the towing device are too narrow to cover the spanboard, making it impossible to place the vehicle on top of the truck. Therefore, the vehicle traction device of the present invention attempts to solve all of the above-mentioned drawbacks by separately forming wheel holders to place and hold the left and right wheels of the accident vehicle and towing the vehicle with cables.

0004

[Means for Solving the Problems] The vehicle traction device of the present invention comprises a pair of wheel holders for respectively mounting and holding both left and right wheels of a vehicle such as an automobile. The long side rods are arranged horizontally and parallelly at appropriate intervals, and rollers are attached to both ends of each side long rod, and the end hook of the traction cable is hooked to one end. In addition, between the long rods on both sides, two connecting shafts are removably installed horizontally at both ends so that the distance between the long rods can be widened or narrowed as the side long rods expand and contract.

[0005]

[Operation] Extend the length measuring rod of the wheel holder, then loosen the bolt on one side to separate both length measuring rods. Then, the two vehicle receivers with the length measuring rods separated were placed so that the length measuring rods were located at the inner and outer positions of both the left and right wheels, including the wheel that could no longer rotate due to the accident, and the connecting shafts were located at the front and rear positions of the wheels. Then reinsert the connecting shaft into the bearing and tighten the bolts to integrate. In this state, the measuring rod is retracted and the wheel is placed and held between the connecting shafts so that the wheel is sandwiched between the two connecting shafts from the front and back. next,
The distal end hook of the towing cable is hooked to a locking part provided at one end of the side long rods located at bilaterally symmetrical positions, and the automobile is towed by pulling the cable.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle traction device according to the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a wheel support for mounting and holding the wheels V of the accident vehicle being towed, and both left and right wheels V, V
Two symmetrical shapes are used to place one each.

Each wheel support 1 is made up of a pair of long side rods 2, 2 which are extendable and retractable in the longitudinal direction and arranged horizontally and parallel to each other with a distance slightly wider than the width of the wheel V. It consists of a square tube-shaped fixed member 3 whose front end is closed and whose rear end is open, and a movable member 4 whose both ends are closed and which is fitted into the fixed member 3 from behind. In addition, as shown in FIG. 2, a screw shaft with a narrow diameter portion 5 at one end inserted into a through hole 6 provided on the front end face and supported, and a hexagonal high nut 7 fixed to the tip of the screw shaft, as shown in FIG. At the same time, the threaded shaft 8 is screwed through a through hole 9 formed in the front end face of the movable member 4 into a threaded bearing 10 continuously provided on the rear face thereof. Then, by applying, for example, an impact wrench (not shown) to the high nut 7 and rotating it, the movable member 4 is slidably extended and contracted with respect to the fixed member 3.

Further, fixing plates 11 extending outward are attached to the front end upper surfaces of the left and right fixed members 3, 3 and the rear end upper surfaces of the movable members 4, 4, respectively, and a horizontal surface is attached to the lower surface of each fixed plate 11. A rotatable support plate 12 is provided vertically within the support plate 1, and each support plate 1
A roller 13 is pivotally attached to each of the rollers 2 and 2. Furthermore, the fixing member 3,
The support plates 12, 12 on the third side are each provided with a locking portion 15 extending inwardly and having a vertical hole 14. In this embodiment, the rollers 13' located on the outside of each wheel support 1, 1 have a larger diameter than the rollers 13 located on the inside.

Furthermore, both fixed members 3, 3 and movable members 4, 4
Bearings 16a, 16a and 16 are arranged opposite to each other between the inner surfaces of the
b, 16b are fixed respectively, and two connecting shafts 17a, 1
7b to each bearing 16a, 16a and 16b, 16
b and is removably fixed with bolts 18. Each connecting shaft 17a, 17b has a bearing 1 that supports both ends.
A cylindrical body 20 is attached via 9 and 19, so that the wheels V of the accident vehicle can be easily placed on top of the cylindrical body 20.

[0010] Accordingly, the present invention has the above-mentioned configuration, and is capable of handling wheels V which are unable to rotate due to an accident of a car to be towed.
The two high-height nuts 7, 7 are rotated so that the movable members 4, 4 are moved forward, and the side long rods 2, 2 are extended. Then, loosen the bolts 18, 18 on one side and remove the long rods 2, 2 on both sides.
These two wheel supports 1, 1 are connected to both left and right wheels V,
The side long rods 2, 2 come to the inside and outside positions of V, and the connecting shafts 17a, 1
7b is located at the front and back position of the wheel V, and the connecting shaft 1
7a and 17b are reinserted into the bearings 16a and 16a and bolted to integrate them. In particular, the large-diameter rollers 13' of each wheel support 1, 1 are placed on the outside of the vehicle, making it easy to place them on the underside of the vehicle. In this state, for example, apply an impact wrench (not shown) to each high nut 7, 7, rotate the screw shafts 8, 8 to contract the long rods 2, 2 on both sides, and connect the connecting shafts 17a, 17b to the wheel V. is placed and held between the connecting shafts 17a and 17b so as to sandwich it from the front and back.

[0011] Next, the connecting tools 21, 21 are inserted into the vertical holes 14, 14 of the locking parts 15, 15 located on the outside of both wheel receivers 1, 1.
The hooks 23 and 23 attached to both ends of the towing cable 22 are engaged with these connectors 21 and 21, and the hooks 23 and 23 attached to the pulley 24 that are engaged with the towing cable 22 are separately hooked to the hooks 23 and 23, respectively. By hooking the hook 27 at the tip of the tension cable 26 and pulling the tension cable 26, the accident vehicle is towed. Usually, the tension cable 26 is a wire attached to a truck such as a winch (not shown). A pair of spanning boards (not shown) are diagonally spaced apart from each other, and a winch is driven to pull the accident vehicle onto the track along the spanning boards.

In this embodiment, the rollers 1 of the wheel support 1
3' was made to have a large diameter, but this is because some of the above-mentioned spanning boards have a mesh shape, and when the small diameter roller 13 is placed on the spanning board, it fits into the mesh and does not come off. This is to prevent the accident vehicle from becoming unable to move itself, and if this is not necessary, small diameter rollers may be used for both.

[0013]

[Effects of the Invention] As described above, according to the vehicle traction device of the present invention, wheel receivers are separately provided to place and hold each wheel, and these are towed by cables. Since it is smaller in size and lighter in weight, it can be moved with a relatively small force and is easy to operate. In addition, since the wheel holder is downsized and has a structure that can be disassembled, it is not necessary to take up a large storage space, making effective use of the space, and it is also compact, making it extremely convenient for transportation. Furthermore, the manufacturing cost can be kept low and it is economical. Furthermore, it has many advantages such as being able to be mounted on a truck using a mesh-like span plate, which was not possible with conventional towing devices, expanding the range of use and increasing the value of use.
