Description

[Detailed description of the invention] Industrial application field The present invention relates to the improvement of the hook body of a hook consisting of an eye body and a hook body. In particular, when a large number of hook bodies are plated, two hook bodies are in an abeta state. That is, it relates to a hook body that prevents the hook from becoming in a coupled state.

BACKGROUND ART A hook body A shown in FIG. 6 consists of a front flat plate 1 and a back flat plate 2 integrally formed into a substantially horizontal U-shape, into which an eye body (not shown) is inserted and engaged. Width W of the insertion slot 3 formed by the front flat plate 1 and the back flat plate 2
is somewhat wider than the wall thickness T of the front flat plate 1 and the back flat plate 2.

Problems to be Solved by the Invention Therefore, when a large number of hook bodies A are plated at the same time, two hook bodies A are inserted into each other's insertion openings 3 with either the front flat plate 1 or the back flat plate 2. If the two hook bodies A are inserted into each other, the two hook bodies A may be placed in an abaxial state, that is, in a joined state, resulting in a problem that plating, etc., cannot be performed sufficiently.

The present invention has been developed with the above-mentioned points in mind. Even when a large number of hook bodies are plated at the same time, the present invention prevents the hook bodies from being joined together in an uneven state, and allows individual hook bodies to be individually plated. It is an object of the present invention to provide a hook body for a hook hook whose body can be sufficiently plated.

Means for Solving the Problems According to the present invention, the above-mentioned problems are solved in the hook body of a hook in which a front flat plate and a back flat plate are integrally formed in a substantially horizontal U-shape. A blocking means for preventing the front flat plate or the back flat plate itself from being inserted and engaged into the insertion opening formed by the front flat plate and the back flat plate is provided on the front end side of the front flat plate and the back flat plate so as to protrude outward. resolved.

Embodiments Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Figures 1 to 3 show the hook body A according to the present invention.
The hook body A is basically formed by integrally forming a front flat plate 1 and a back flat plate 2 into a substantially horizontal U-shape.

Reference numeral 3 denotes an insertion opening into which an eye main body (not shown) is inserted and engaged, and the insertion opening 3 is formed by the front flat plate 1 and the back flat plate 2.
It has a width W that is somewhat wider than the wall thickness T of.

The front flat plate 1 has a protrusion 4 protruding outwardly on its tip side, and the back plate 2 also has a protrusion 5 protruding outwardly on its tip side. Each of the protrusions 4 and 5 on the front flat plate 1 and the back flat plate 2 serves as a blocking means for preventing the front flat plate 1 or the back flat plate 2 of another hook body A from entering into the insertion opening 3. That is, since the width D from the inner surfaces 6, 6 of the front flat plate 1 and the back flat plate 2 to the tops 7, 7 of each protrusion 4, 5 is configured to be wider than the width W of the insertion opening 3, , front flat plate 1 or back flat plate 2
Even if the front plate 1 or the back plate 2 tries to enter the insertion opening 3, the protrusions 4 and 5 get stuck at the entrance, and the front flat plate 1 or the back flat plate 2 is prevented from entering the insertion opening 3.

Reference numeral 8 denotes a hole formed in the front flat plate 1 for inserting a caulking punch, and on both side edges of the hole 8 there are locking protrusions that protrude inward to make it difficult to disengage from the eye main body. Sections 9, 9 are provided.

On the back flat plate 2, a embossed portion 10, which is embossed from the inside to the outside by press working or the like, is formed at a location facing the hole 8 (see FIGS. 2 and 3). Holes 11, 11 are formed through which the claws of a stopper (not shown) are inserted.

FIG. 4 shows another embodiment, in which the protrusion 4 of the embodiment shown in FIGS. 1 to 3,
5, an example is shown in which two protrusions 12, 12 are provided on the front end sides of the front flat plate 1 and the back flat plate 2, which are spaced apart in the width direction. Even if the protrusions 12, 12 are provided on the front flat plate 1 and the back flat plate 2 in this way, the front flat plate 1 and the back flat plate 2 cannot enter the insertion opening 3 due to the protrusions 12, 12, as in the first embodiment. This prevents the so-called two hook bodies A from being connected in an abloc state.

FIG. 5 shows still another embodiment in which the protrusions 4, 5 and the protrusions 12, 12, which are the blocking means for preventing the two hook bodies A from being combined in the abject state, are replaced. , shows an example in which the front flat plate 1 and the back flat plate 2 are provided with bent portions 13, 13, which are formed by bending the tips of the front flat plate 1 and the back flat plate 2 outward. That is, the bent portion 13 is bent outward so that the width D from the inner surfaces 6, 6 of the front flat plate 1 and the back flat plate 2 to the top 14 of the bent portion 13 is wider than the width W of the insertion opening 3. In this way, the bent portion 13
By providing these on the front flat plate 1 and the back flat plate 2, the front flat plate 1 and the back flat plate 2 are prevented from entering the insertion opening 3, and the two hook bodies A are prevented from being connected in an abloc state.

Function The hook body A according to the present invention has the above-mentioned structure, and even when a large number of hook bodies A are plated at the same time, the protrusions 4 and 5 are provided on the front end sides of the front flat plate 1 and the back flat plate 2. , protrusion 12 and bent portions 13 , 13
Since this is provided, the front flat plate 1 and the back flat plate 2 of the two hook bodies A do not enter into the insertion opening 3 and are combined in an abaxial state. That is, to explain the embodiment shown in FIGS. 1 to 3, the width D, which is the height of the protrusions 4 and 5 provided on the front flat plate 1 and the back flat plate 2, is the width D of the insertion opening 3 of the hook body A. Since it is wider than the width W, even if the front flat plate 1 or the back flat plate 2 tries to enter the insertion opening 3, the protrusions 4 and 5 get caught at the entrance and are prevented from entering. Therefore, even if a large number of hook bodies A are to be plated at the same time, two hook bodies A will not be joined in an uneven manner, and each hook body A can be sufficiently plated.

Effects of the Invention As described above, according to the present invention, a blocking means is provided on the tip end sides of the front flat plate and the back flat plate constituting the hook body to prevent the front flat plate or the back flat plate themselves from entering the insertion slot. Therefore, even when a large number of hook bodies are plated at the same time, the hook bodies will not be joined together in an uneven state.
This has the practical effect that each hook body can be sufficiently plated.
