[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook wire retaining hook.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional sling hook, which has a hook body 1'to prevent the wire from coming off.
It is known to provide a spring-repellent wire disengagement pawl 2 ′ toward the tip K.

[0003]

In order to hang the wire on the hook body 1'or remove the hung wire with the above-mentioned conventional structure, the wire disengagement pawl 2'is preliminarily attached to the spring. It is necessary to release the tip K of the hook body 1 ′ by pressing with a finger against the arrow F in the direction of arrow F. At this time, however, there is a problem that the wire comes into contact with the pressing finger to scratch the finger. is there.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and the structure is such that the tip of the hook is applied upward from the inner surface of the root of the hook by the repulsive force of the spring. It is characterized in that a recess g sufficient for inserting a finger when pressing is provided on the front surface side of the wire detachment preventing claw which is in contact, and an engaging groove m for forming a hook tip and a contact surface is provided on a lower end edge. To do.

[0005]

1 is a perspective view of an improved wire disengagement pawl 2 according to the present invention, in which the spring tip is abutted upward from the inner surface side of the hook root by the resilient force of a spring. In addition, a recess g is formed on the surface side of the wire disengagement prevention claw 2 that is sufficient for the fingertip to be depressed. m is an engaging groove for forming a contact surface with the tip of the hook.

FIG. 2 is a view of the mounting state, in which a spring 3 is used on the support shaft side, and the engaging groove m at the tip of the toe is always in elastic contact with the tip K of the hook body 1.

FIG. 3 is a view showing the state of use. In the present invention, when a wire is to be hooked, a fingertip is hooked in the recess g of the wire disconnection preventing claw 2 and pressed in the direction of arrow F as shown in the figure. At this time, since the finger 4 is depressed in the recess g of the disengagement prevention claw 2, the wire passing gap S is formed to be large, and the wire and the fingertip do not come into contact with each other. It is a thing. This also applies to the case of removing the wire. The above embodiment is an example of use for a sling hook, but the present invention can also be applied to a hook for a power shovel, a swivel hook, a choker hook, and the like to prevent the hook from coming off, which is another embodiment of the present invention. And

[0008]

As described above, according to the present invention, the recess g which is sufficient to cause the fingertip to be depressed into the wire disengagement preventing claw 2 which is abutted upward from the inner surface of the base of the hook by the elastic force of the spring.
By providing the wire retaining hook 2 simply by putting a finger in the recess g of the wire stopper claw 2 and pushing it down, the hook 2 for preventing the stopper 2 and the tip k of the hook body 1 can be easily attached when hooking or removing the wire in various hooks. When the wire is hooked or the wire is removed, the wire does not come into contact with the fingertip pressing the detachment preventing claw 2. In addition, the disengagement preventing claw 2 can be reliably and strongly pressed.
