Description

[Detailed description of the invention] [Industrial application field] This invention relates to a hook used for hanging picture frames, etc., and in particular, it is attached to the lower end of a wire hanging from the ceiling along the wall so that it can move up and down. This invention relates to a hook for hanging.

[Conventional technology]

2. Description of the Related Art As a hanging hook used for hanging a picture frame or the like, those shown in FIGS. 6 and 7 have been known. In each of these, a wire gripping portion is provided inside the hook body 21, and the wire 22 passed through the hook body 21 is restrained at an arbitrary position. Further, a hook metal fitting 23 is attached to the lower end of the hook body 21, and a hanging string 25 of the picture frame 24 is hung on the hook metal fitting 23.
The hook fitting 23 in FIG. 6 is attached to the center line of the main body 21, that is, closer to the front than the wire 22, and the wire 22 passes behind the hook fitting 23. The hook fitting 23 shown in FIG. 7 is attached to the hanging part of the main body 21, and is provided with a passage hole 28 for the wire 22.

In the case of FIG. 6, a spacer 26 made of rubber or the like is attached to the back of the main body 21, and in the case of FIG.
6 are attached and each applied to the wall surface 27,
The distance between the hook body 2 and the wall surface 27 is maintained constant.

[The problem that the idea aims to solve]

If the hook fitting 23 is mounted toward the front as shown in FIG. 6, there will be a gap between the point where the load is applied and the wire 22, so the hook body 21 will tend to lean toward the wall surface 27. Therefore, it is necessary to prevent the hook body 21 from tilting by attaching a spacer 26 to the hook body 21.

In addition, in the case of Figure 7, the point where the load acts,
Although the positions of the wires 22 are relatively close to each other, there is still a tendency to tilt the hook body 21, so a spacer 26 is required, and since the wire passage hole 28 is provided in the hook fitting 23, there is a disadvantage that the strength is reduced.

Further, since each of these hook fittings 23 is formed by bending a metal plate, it has a required width. For example, when hanging a large picture frame 24 as shown in FIG. 8, the hook fitting 23 has the required width.
When correcting the inclination of item 4, use the hanging string 25 and the hook fitting 2.
3, the sliding contact resistance becomes large and there is an inconvenience that the inclination cannot be smoothly corrected.

Therefore, the technical objective of this invention is to provide a hanging hook that solves these problems.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a hanging hook consisting of a hook body, a hook metal fitting attached to the lower end of the hook body, and a wire gripping part provided inside the hook body. The main body is provided with a wire guide groove, the lower end of the wire guide groove is opened to the outer surface of the hook main body, and the hanging part of the hook metal fitting is arranged directly below the hook main body.

[Effect]

The wire inserted into the hook body is gripped by the wire gripping part inside the hook, and the part below the gripping part is pulled out to the outside of the hook body through the open part at the lower end of the wire guide groove. The exposed wire hangs downward due to its own weight.

Further, the point at which the load is applied to the hanging portion of the hook and the wire inserted through the hook body are located on the same line.

〔Example〕

As shown in FIGS. 1 and 2, the hanging hook of the embodiment has a cylindrical case 2 screwed to the upper half of the hook body 1. As shown in FIGS. The upper half of the case 2 is formed into a tapered shape. A ball holding member 3 is inserted into the case 2 so as to be vertically movable, and its upper end protrudes from the upper end of the case 2.

The ball holding member 3 has a tapered portion 4 that matches the tapered portion of the case 2, and three ball holes 5 are provided at three equal positions in the circumferential direction of the tapered portion 4. A wire insertion hole 6 passes through the center of the ball holding member 3, and each ball hole 5 communicates with the wire insertion hole 6. The balls 7 inserted into the ball holes 5 partially protrude into the wire insertion holes 6, and the wires 8 are held between each ball 7.

A spring receiving step 9 is formed in the middle of the ball holding member 3, and a spring receiving nut 10 freely passes through the portion below the step 9. The spring receiving nut 10 is screwed to the inner peripheral surface of the case 2.

A spring 11 is interposed between the spring receiving step portion 9 and the spring receiving nut 10, and the tapered portion 4 of the ball holding member 3 is pressed against the inner surface of the tapered portion of the case 2.

As shown in FIG. 4, in the upper half of the hook body 1, there is a wire guide groove 12 which starts from a slit having a required width in the radial direction including the center of the upper end surface and gradually becomes shallower as it goes downward. provided. The wire guide groove 12 extends below the threaded portion 13 for screwing the case 2 together, and is opened at the side surface of the hook body 1 below the case 2. Further, a vertical groove 14 is formed on the opposite surface of the wire guide groove 12 from the upper end of the hook body 1, and is adapted to receive the lower end portion of the aforementioned ball holding member 3.

Hook metal fitting 15 is placed in the center of the lower end surface of the hook body 1.
are screwed together. The hook fitting 15 is formed by bending a round metal bar, and its hanging portion 16 is formed so as to hang down from the wire insertion hole 6 of the ball holding member 3.

The hanging hook of this embodiment is constructed as described above and is used as shown in FIG. That is, a hanger 18 is attached to a hanging rail 17 fixed to the ceiling, and the upper end of the wire 8 is hung on the hook 19. The lower end portion of the wire 8 is pulled out diagonally downward from the open portion at the lower end of the wire insertion hole 6 of the ball holding member 3 of the hanging hook of the present invention through the wire guide groove 12, and hangs downward. When a load is applied to the hook fitting 15, the hook main body 1 and the case 2 move slightly in opposite directions, and as a result, the ball 7 is pushed inward and the wire 8 is clamped.

A hanging string 20 hung on the hook fitting 15 is hung on a hanging portion 16 of the hook fitting 15, and the hanging string 20 is located directly below the vertical portion of the wire 8.

[Effect of idea]

As described above, this invention allows the wire inserted into the hook body to be pulled out to the side of the hook body by providing the wire guide groove open on the outer surface of the hook body below the wire insertion hole.
Therefore, the hook metal fitting can be installed directly below the hook body, and the point where the load is applied is located on the same line as the position of the wire that suspends it, so the wire and the hanging hook will not tilt. . Therefore, no spacer is required to correct the inclination.

In addition, as in the example, the hook metal fittings can be made of round bars, reducing the frictional resistance with the hanging string, making it easy to adjust the inclination of the frame when hanging from two locations as shown in Figure 8. It is possible to increase the strength compared to those made of metal plates.
