[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to hook fittings for suspending large and heavy exhibits.

[0002]

2. Description of the Related Art A conventional hook fitting is illustrated in FIGS. As shown in FIG. 9, the hook fitting has a spring receiving portion 22 screwed onto a shaft 21a of the hook portion 21,
A coil spring 23 and a washer 24 are passed through a shaft 21a of the hook portion 21, and a runner portion 25 is screwed and fixed to an end of the shaft 21a of the hook portion 21.
The coil spring 23 fits into the hole 22a of the spring receiving portion 22, projects from the hole 22a, and presses the washer 24 against the runner portion 25.

FIG. 10 shows a state in which the hook fitting is attached to the guide rail. This guide rail 26
Has an elongated opening 26a and is fixed to a wall surface or a ceiling. A plurality of hook fittings are attached to the guide rail 26, and wires are stretched between the hook fittings and the exhibit to suspend the exhibit.

11 and 12 show a procedure for attaching the hook fitting to the guide rail 26. First, as shown in FIG. 11A, the spring receiving portion 22 of the hook fitting is moved downward and the runner portion 25 is inserted into the opening 26 a of the guide rail 26. Since the lateral width of the runner portion 25 is narrower than that of the opening portion 26a,
As shown in (b), the longitudinal direction of the runner portion 25 and the opening 2
When 6a is made parallel, this runner portion 25 is opened
It can be put in a. Further, when the hook portion 21 is pushed upward, the runner portion 25 is also pushed up. at the same time,
The washer 24 hits the spring receiving portion 22, and the coil spring 23 contracts and fits into the hole 22 a of the spring receiving portion 22.

Subsequently, as shown in FIG. 12 (b), the hook metal fitting is rotated by 90 °, and the hook portion 21 is released as shown in FIG. 12 (a). Then, the hook portion 21 and the runner portion 25 descend. At this time, since the convex portion 25a of the runner portion 25 is fitted into the opening portion 26a, the orientation of the hook portion 21 is determined. In this state, the spring receiving portion 22 is rotated so that the spring receiving portion 22 is inserted through the washer 24 into the guide rail 2
Press on 6. As a result, this hook fitting is fixed to the guide rail 26.

[0006]

By the way, when the hook fitting is attached to the guide rail 26, the appearance of the runner portion 25 inside the guide rail 26 is obscured by the washer 24 and cannot be seen. Therefore, the protrusion 25a of the runner portion 25 is confirmed to fit into the opening 26a by checking the feeling.

However, the convex portion 25 of the runner portion 25
If the opening 26a of the guide rail 26 is too wide, or if both edges of the opening 26a are thinner than a, the sufficient feel cannot be obtained and the workability is significantly reduced.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hook fitting which gives a clear feel to the runner portion fitted in the opening of the guide rail.

[0009]

In order to solve the above problems, in the hook fitting of the present invention, a substantially square convex portion is formed on the bottom, and a vertically long runner portion having the same lateral width as the convex portion is provided. , The hook portion protrudingly provided on the convex portion of the runner portion, the spring receiving portion screwed into the male screw around the axis of the hook portion, the washer interposed between the runner portion and the spring receiving portion, and when reduced. And a coil spring that fits in the spring receiving portion and projects from the spring receiving portion to press the washer against the runner portion. The washer is formed with a pair of engaging claws that face each other and sandwich the convex portion of the runner portion.

[0010]

In the hook fitting of the present invention, the convex portion on the bottom of the runner portion is substantially square, and a pair of engaging claws sandwiching the convex portion of the substantially square are formed on the washer. The engaging claws of the washer sandwich the substantially square convex portion of the runner portion in two directions orthogonal to each other. Here, the approximately square convex portion of the runner portion is fitted in advance between the engaging claws of the washer, the runner portion is inserted into the opening of the guide rail, and the hook metal fitting is rotated by 90 °. , Attach this hook fitting to the guide rail. At this time, since each engaging claw of the washer is caught in the opening of the guide rail, the washer does not rotate. Also,
With the rotation of the runner portion, the substantially square convex portion is once disengaged from between the engaging claws of the washer, and is fitted therein again.
Due to this re-fitting, even if the opening of the guide rail is too wide or both edges of this opening are thin, a sufficient feeling can be obtained and workability is not deteriorated.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 6 show an embodiment of a hook fitting of the present invention. As shown in FIG. 1, the hook fitting of this embodiment includes a hook portion 1, a spring receiving portion 2, a coil spring 3, a washer 4, and a runner portion 5. A substantially square convex portion 5a is formed on the bottom of the runner portion 5, and a cylindrical body 5b is projectingly provided on the lower surface of the convex portion 5a.

The washer 4 and the coil spring 3 are passed through the tubular body 5b of the runner portion 5, and the spring receiving portion 2 is screwed into the tubular body 5b. The coil spring 3 fits into the hole 2a of the spring receiving portion 2 and presses the washer 4 against the runner portion 5. Also,
The shaft 1a of the hook portion 1 is screwed into and fixed to the tubular body 5b of the runner portion 5. As a result, the hook fitting as shown in FIG. 2 is assembled.

A pair of engaging claws 6 are provided on the upper surface of the washer 4.
Are formed. The interval between these engaging claws 6 is longer than one side of the substantially square convex portion 5a of the runner portion 5. Therefore, the substantially square convex portion 5a of the runner portion 5 is sandwiched between these engaging claws 6. In FIG. 2, the protrusion 5 a of the runner portion 5 is fitted between the engaging claws 6 with the longitudinal direction of the runner portion 5 and the direction in which the engaging claws 6 of the washer 4 are aligned. There is. In addition, the convex portion 5 of the runner portion 5
Since a is substantially square, even when the runner portion 5 is rotated by 90 °, the convex portion 5a of the runner portion 5 is fitted between the engaging claws 6.

Now, as shown in FIG. 3A, the spring receiving portion 2 is moved downward and the runner portion 5 is inserted into the opening 11a of the guide rail 11. When the hook portion 1 is pushed upward, the washer 4 is pressed against the guide rail 11 by the coil spring 3, and the runner portion 5 is pushed up inside the guide rail 11. At this time,
As shown in (b), the longitudinal direction of the runner portion 5 is aligned with the direction in which the engaging claws 6 of the washer 4 are aligned, and the engaging claws 6 of the washer 4 are aligned with the opening 11 a of the guide rail 11.
Get in.

As shown in FIGS. 4 (a) and 4 (b), when the hook portion 1 is rotated by 90 °, the runner portion 5 is also rotated, but the engaging claws 6 of the washer 4 are guided. Since it is caught in the opening 11a of the rail 11, the washer 4 does not rotate. When the hook portion 1 is released after the hook portion 1 is rotated, the convex portion 5a of the runner portion 5 is fitted again between the engaging claws 6 of the washer 4 as shown in FIG. At the same time, the convex portion 5a of the runner portion 5 also fits into the opening portion 11a of the guide rail 11. Therefore, the convex portion 5 a of the runner portion 5 is formed between the engaging claws 6 of the washer 4 and the opening portion 1 of the guide rail 11.
It will be double fitted to 1a. As a result, the feel when the convex portion 5a of the runner portion 5 is fitted becomes clear, and this can be easily recognized.

Thereafter, as shown in FIG. 6, when the spring receiving portion 2 is rotated and the spring receiving portion 2 is tightened, the hook fitting is fixed to the guide rail 11.

If the opening 11a of the guide rail 11 is too wide or both edges of the opening 11a are thin, the feel obtained by fitting into the opening 11a is weakened, but the respective engagements of the washers 4 are reduced. Since the feel obtained by fitting between the claws 6 does not change, it is not difficult to recognize this.

Further, the fact that the feel of fitting can be easily recognized also means that the direction of the runner portion 5 can be easily recognized. Therefore, as shown in FIG. It is possible to prevent an error that the hook fitting is attached to the guide rail when the portion 5 is obliquely arranged. The state in which the runner portion 5 is obliquely arranged causes an accident in which the hook fitting is disengaged from the guide rail due to a slight impact or vibration.

Further, as shown in FIG. 8, with the spring receiving portion 2 loosened, the hook metal fitting is attached to the guide rail,
The wire between this hook and the exhibit may be stretched diagonally. In this case, half of the convex portion 5a of the runner portion 5 comes off from the opening 11a of the guide rail,
Since the convex portion 5a of the runner portion 5 is surely hooked to the one engaging claw 6 of the washer 4, the hook metal fitting will not come off. In comparison with this, in the conventional hook metal fitting, since the convex portion of the runner portion is only caught in the opening of the guide rail, the hook metal fitting is easily detached.

Further, this hook metal fitting is used for the guide rail 11
To remove the hook from the hook, the procedure from FIG. 3 to FIG. 6 may be reversed, but when the hook 1 is released at the last step in FIG. Since the fitting is performed between the engaging claws 6, the clear feel at this time recognizes that the longitudinal direction of the runner portion 5 and the opening portion 11a are parallel to each other, and the runner portion 5 is quickly moved from the opening portion 11a. Can be removed.

[0022]

As described above, in the hook metal fitting of the present invention, when the runner portion is inserted into the opening of the guide rail and the hook metal fitting is rotated by 90 °, a substantially square convex portion of the runner portion is formed. It fits between the engaging claws of the washer and gives a clear feel to the operator, so that workability can be improved.
