Description of the Related Art A conventional technique relating to a pintle hook is disclosed in Japanese Utility Model Laid-Open No. 3-60103. 5, 6, and 7 show the prior art of the present invention. FIG. 5 is a front view of a pintle hook, FIG. 6 is a plan view, and FIG. 7 is a side view. In FIG. 5, the hook member 10
0 has a U-shaped hooking portion 100a that is curved upward and is formed on the left side of the base portion 100b in FIG. Further, the base portion 100b of the hook member 100 has a mounting hole 100d for mounting on the frame of the vehicle. The lock member 200 shown in FIG. 5 is bifurcated at one end on the right side in FIG. 5, as shown in FIG. The lock member 200 having one forked end on the right side in FIG.
It is rotatably supported by a bolt 400 on b. When the lock member 200 is in the closed position as shown in FIG. 5, the lock member 200 is formed with an elongated hole 200a extending downward from the hole pivotally supported by the bolt 400.
Further, when the lock member 200 is closed, the hooking portion 10
The lock member 200
A protrusion 100c is provided to prevent the rotation of the. That is, when the lock member 200 is in the closed state as shown in FIG. 5, the lock member 200 is brought into contact with the protruding portion 100c due to its own weight, the lock member 200 is rotated, and the latch portion 100a is opened.

Even if an object is hooked on a and a shock or the like is received during work such as towing, the lock member 200 does not rotate.
Attach the end of the towbar or wire rope to the hook 10
When the lock member 200 is opened to be hooked on 0a, the lock member 200 is moved upward along the long hole 200a. As a result, the bolt 4 of the lock member 200
5, one end of which is pivotally supported becomes rotatable to the right in FIG. 5 above the protruding portion 100c, so that the lock member 200 rotates to the position indicated by the chain double-dashed line in FIG. . In addition, when closing, it can be easily closed by operating in the reverse direction of opening. Such a pintle hook is easy to operate and has a lock member 200.
The closed state of can be reliably maintained. In addition, even if there is some error in manufacturing parts, it is acceptable as long as the above-mentioned function is not impaired, so it can be used as-cast without any special processing, and can be manufactured efficiently and inexpensively. .

まうことがない。The lock member and the U-shaped hook member are rotatably attached at one end of the lock member and the base of the hook member. A first engaging portion and a second engaging portion for engaging the lock member and the hook member are provided at the other end portion of the lock member and the end portion of the hook member on the hook portion side. ing. Further, the lock member is provided with a movement restricting portion that restricts a moving direction and a moving distance of the lock member, and the movement of the lock member allows the first engaging portion of the hook member to be engaged with the second engaging portion of the lock member. Engage the parts. Further, in order to prevent the engagement between the second engaging portion of the lock member and the first engaging portion of the hook member from being disengaged, the urging member that urges the engagement so as not to disengage is the hook member. Attached to. When hooking a tow bar or a wire rope on the pintle hook, the lock member is slid against the biasing force of the biasing member. When the lock member slides a certain distance, the second engaging portion of the lock member and the first hook member of the hook member
The engagement by the engagement portion is released. As a result, the lock member rotates upward about the rotation shaft around which the lock portion and the hook member are pivotally supported. Then, the tow bar or wire rope hooked on the pintle hook is hooked on the U-shaped hook member. After that, the reverse operation of removing the lock member from the hook member is performed to engage the lock member with the hook member. In the pintle hook configured as described above, the biasing member biases the lock member in a direction in which the second engagement portion of the lock member and the first engagement portion of the hook member are not disengaged from each other. Therefore, no matter which direction the force is applied to the pintle hook, the lock member and the hook member are not disengaged from each other, and the lock member does not rotate upward.

When hooking a tow bar or a wire rope, the handle 2a of the lock member 2 shown in FIG. 1 is moved in the L direction. As shown in FIG. 3, the lock member 2 includes the cutout portion 1.
When it is moved in the L direction by the distance M along the slide surface 1d 3 of d, the slide receiving portion 1c, and the fitting hole 1e, the first back surface 2b 1 of the lock member 2 and the first contact surface 1d of the hook member.
1 contacts, and the slide portion 2c of the lock member 2 and the slide receiving portion 1c of the hook member 1 are disengaged. As a result, the lock member 2 can be rotated in the N direction shown in FIG. The lock member 2 rotates in the N direction shown in FIG. 3, and FIG. 4 shows a state in which the lock member 2 does not rotate any more. That is, when the lock member 2 is fully opened as shown in FIG.
Since the second rear 2b 2 and the first abutment surface 1d 1 of the hook member 1 is in contact, more locking member 2 is not rotated. At this time, the bottom surface 2b 3 of the lock member 2 and the hook member 1
The second contact surface 1d 2 of is also in contact. In order to maintain this state, the spring 4 biases the second back surface 2b 2 of the lock member 2 to fix the lock member 2. In this state, the tow bar or the wire rope is hooked on the U-shaped hooking portion 1a of the hook member 1. When the lock member 2 moves in the L direction shown in FIG. 3 and the moved distance is less than M, the slide portion 2c
And the slide receiving portion 1c are engaged with each other, the lock member 2 does not rotate in the N direction shown in FIG.

4, the hook portion 2 is rotated in the P direction shown in FIG. 4, and the slide portion 2c of the lock portion 2 is moved to the slide receiving portion 1c of the hook portion 1 as shown in FIG.
At the time of hitting, the slide portion 2c is moved in the Q direction to be engaged with the slide receiving portion 1c. Further, the hook portion 2 is biased by the spring 4 in the Q direction shown in FIG. 3, that is, in the direction in which the slide portion 2c and the slide receiving portion 1c are engaged. Therefore, unless a force (intentionally operated by a person, etc.) that exceeds the urging force of the spring 4 such as the lock member 2 is directly pushed in the L direction is applied from the outside, the engagement between the slide portion 2c and the slide receiving portion 1c. I can not come off. In addition, by the wire rope or the tow bar hooked on the hanging portion 1a, the X direction in FIG.
No matter if the force is applied from the Y direction or the Z direction, it will not come off. At this time, the force urged in the X direction and the Y direction is received by the hook member 1, and the force urged in the Z direction is received by the lock member 2.

ことができる。The pintle hook according to the present invention is provided with the engaging portion for engaging the hook member and the lock member, and the urging member for holding the engagement at the engaging portion.
The lock member is provided with a movement restricting portion that restricts a moving direction and a moving distance. When the lock member moves, the engaging portion engages to prevent rotation of the lock member and rotates the lock member. It is dismissed to let. Further, even if a load such as a tow bar or a rope hooked by the biasing member acts from any direction of the pintle hook, the hook member and the lock member are not disengaged from each other and the lock member is not opened. As described above, with a simple configuration, it is possible to obtain a pintle hook in which the lock member does not open regardless of the direction of the load of the towbar, the wire rope, or the like acting on the pintle hook.
