Description

[Detailed explanation of the invention] This invention relates to a car towing and transport vehicle that tows and transports broken down cars, illegally parked cars, etc.
A horizontal frame equipped with a wheel holder for mounting the wheels of a towed vehicle such as a parking violation vehicle is movably mounted on the chassis of a transport vehicle, and a rail that extends to the rear of the chassis and is movable is mounted on the chassis. The rail and the horizontal frame can be easily and securely fixed on the chassis by a simple stopper mechanism. Side frames having a U-shaped cross section are arranged in parallel on both sides with their opening surfaces facing each other, and a rail is slidably inserted into the groove of the side frames,
A horizontal frame having wheel receivers on both sides for mounting the wheels of the towed vehicle is arranged in a state of intersection with the vehicle chassis, and is movable along the side frame of the vehicle chassis and a rail extending behind the side frame. A rotating shaft that is mounted and rotated by a handle on one side of the vehicle chassis is mounted in the longitudinal direction of the vehicle chassis, and an engagement piece is mounted on the rear part of the rotating shaft.
An engagement arm is provided at the front part, and the engagement piece is inserted into the engagement recess cut out in the upper wall of the side frame and the upper wall of the rail, and the engagement piece is inserted into the notch recess of the locking piece protruding from the front part of the side frame. The gist is that the engaging arms are removably engaged with hook pieces protruding from the tip of the frame.

The details of the present invention will be described below with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a vehicle chassis, and side frames 2, 2 each having a U-shaped cross section are disposed on both sides with their opening surfaces facing each other. Reference numeral 3 denotes a rail that is slidably inserted into the grooves 2', 2' of the side frames 2, 2, and is connected and fixed at the front and rear ends by horizontal rods 4, 4. 5
wheel receivers 6 on which the wheels of the towed vehicle are mounted on both sides;
6, which is movably placed on the vehicle chassis 1 in a crossed manner, and has claws 7, 7 protruding downward on both sides that engage with the outer surfaces of the side frames 2, 2. A tube body 9 which is rotatably fitted onto a shaft 8 fixed to the claws 7, 7 is grounded on the side frames 2, 2, and is connected to branches 10, 10 hanging below the horizontal frame 5. Install the locking shaft 11, and connect both ends of the locking shaft 11 to the side frame 2,
2, and both ends of the locking shaft 11 are engaged with the upper walls of the grooves 2', 2' to prevent the horizontal frame 5 from detaching from the chassis 1. do. A gear 12 is mounted on the front and rear of one side frame 2 of the chassis 1,
A chain 14 is engaged with the chain 13, the tip of the rail 3 is connected to this chain with an appropriate fastening device 15, and the rail 3 is moved in the front-back direction by rotating the chain 14 with the handle 16. It is something. Furthermore, a handle 1 is provided on one side of the chassis 1.
8, a rotating shaft 17 is mounted on the shaft, an engaging piece 19 is attached to the rear part of the rotating shaft 17, and an engaging arm 20 bent in an L shape is attached to the front part of the rotating shaft 17. The engaging piece 19 is engaged with the engaging recess 21 cut out in the upper wall of the side frame 2 and the engaging recess 22 cut out in the upper wall of one of the rails 3, so that the rails 3, 3 are connected to the side frames 2, 2. Locking pieces 24, 24 are fixed in the grooves 2', 2' and projectingly provided on the support plate 23 provided at the front part of the chassis 1, and the notch recesses 25, 25 of the locking pieces 24, 24 and the horizontal The horizontal frame 5 is fixed onto the chassis 1 by engaging the engaging arm 20 with a hook piece 26 protruding from the tip of the frame 5. 2
Reference numeral 7 denotes two parallel connecting rods provided at the tip of the chassis 1, and 28 is a traction rod connected to the rear of the towing vehicle, and the rear end of the traction rod 28 is connected to the connecting rod 2.
The hook 29 inserted between the connecting rods 27 and 27 and rotatably attached to the traction rod 28 is engaged with the connecting shaft 30 on the connecting rods 27 and 27, and the elevator 31 fixed to the tip of the connecting rod 27 is connected to the hook 29. Therefore, the rear part of the traction rod 28 is lifted, and by this operation, the entire chassis 1 is tilted toward the rear part.

Then, the chassis 1 is tilted backward as described above, and the rails 3,
3 is extended to the rear of the side frames 2, 2, and then the horizontal frame 5 is moved from the side frames 2, 2 onto the rails 3, 3, and the wheel receivers 6, 6 of the horizontal frame 5 are brought into contact with the ground. The wheels of the towed vehicle are set on the tower, and the elevator 31 is then reversely rotated to return the chassis 1 to a horizontal state, and the winch 3
2 and move the horizontal frame 5 to the chassis 1 using the rope 33.
The rails 3, 3 are housed in the grooves 2', 2' of the side frames 2, 2, and the rotating shaft 17 is rotated by the handle 18, and the engaging piece 19 is moved into the engaging recess 21, 22. The engaging arms 20 are engaged with the notch recesses 2 of the locking pieces 24, 24 to fix the rails 3, 3, and
5, 25 and the hook piece 26 to move the horizontal frame 5 to the vehicle chassis 1.
It will be fixed on top and be towed and transported.

As described above, in this proposal, a rotating shaft rotated by a handle is mounted in the longitudinal direction of the chassis, an engagement piece is provided at the rear part of the rotating shaft, and an engagement arm is provided at the front part, and the engagement piece is detachably engaged with an engagement recess cut into the upper wall of the side frame and the upper wall of the rail, and the engagement arm is detachably engaged with a notched recess of a locking piece protruding from the front part of the side frame and a hook piece protruding from the tip of the horizontal frame, respectively. This allows the rail to be securely and stably fixed in the groove of the side frame, and the horizontal frame to be securely fixed on the chassis, so that the rail will not slip out of the groove of the side frame or the horizontal frame will not come off the chassis during towing and transport, allowing safe travel, and the rail and horizontal frame can be easily fixed or released by simply turning the rotating shaft with the handle, which has the advantages of being extremely simple to operate and very convenient to use.
