[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an adjuster type plastic curtain hook capable of variably adjusting the hanging position of the curtain.

[0002]

2. Description of the Related Art A conventional curtain hook of this type is shown in FIG.
As described in 1, a sliding body 18 having a main body 16 having a curtain fastening rod 15 on the back side and a locking rod 17 for a curtain runner, and having a hook portion at both ends and having a substantially U-shaped cross section. The sliding body 18 substantially surrounds and fits the main body portion 16, and the downward-saw-toothed projection 19 formed on the front surface of the main body portion 16 is engaged with the detent engagement claw formed on the sliding body 18. There is provided a variable suspension position adjusting type that engages at 20.

[0003]

However, the conventional front-engagement type curtain hook of this kind uses a plastic material having poor rigidity, unlike metal, so that when the curtain is hung, the curtain hook is locked to the locking rod. By the action based on the self-weight of the attached curtain, the rotational force that pulls the main body away from the sliding body works around the engaging portion of the downward saw tooth projection with which the engaging claws of the sliding body are engaged, resulting in The engaging claw of the sliding body is easily disengaged from the downward saw tooth projection.

An object of the present invention is to provide a variable hanging position type in which the engaging claws of the sliding portion are not likely to be separated from the downward sawtooth projections of the main body even when the curtain itself acts on the fastening rod during use. The point is to provide plastic curtain hooks.

[0005]

In order to solve the above-mentioned problems, the present invention has a curtain fastening rod on the back side of a main body and slides a hook body for locking the curtain runner on the front side. In the hanging position variable adjustment type curtain hook that can be mounted, the hook body is a slidable body that fits vertically with respect to the guide portion formed on the main body, and a lock that is hooked on the curtain runner. The main body is composed of a rod and a plurality of downward-sawtooth projections formed in the longitudinal direction of the main body and engaging claws that engage with the ratchet to regulate the movement of the locking rod. Has a generally H-shaped cross-section with a collar-shaped portion, the front-side collar-shaped portion serves as the guide portion, and the downward serrated projection is provided on the side surface of the main body portion between the collar-shaped portions. The sliding portion of the hook body that fits into the side brim portion is bent at both ends inward, and has a hook portion facing each other. None was substantially U-shaped cross section, adopts the curtain hooks forming the engaging claw of the detent to the hook.

[0006]

Therefore, even if the self-weight of the curtain acts, unlike the front engagement type in which the self-weight acts as a separating force, the section H
Downward serrated protrusions are provided on the side surface of the main body between the collars of the V-shaped body, and both ends are bent inward to form hooks facing each other, and fitted to the front side collar. In the curtain hook of the present invention in which the detent engagement claw is formed in the hook portion at the sliding portion having a substantially U-shaped cross-section, the downward serrated protrusion between the flange portions is engaged from the side. The self-weight of the curtain acts as an engaging force, and there is no possibility that the engaging claw and the downward saw tooth projection are disengaged.

Further, since the main body portion has a substantially H-shaped cross section having a brim portion on the front side and the back side, it has refracting strength and durability. The sliding part is fitted with the front flange part as the guide part, so the sliding is smooth,
Further, unlike the type in which the entire main body is held, the size can be reduced.

Further, the engaging claws are formed on the hooks of the sliding parts having a substantially U-shaped cross section, with both ends bent inward to form hooks facing each other, and on the front side and the back side of the main body. Since the downward sawtooth projections are engaged between the brim portions, the engaging claws and the downward sawtooth projections are caught on the curtain mounted on the fastening rod, and the curtain interferes with smooth hanging. There is no risk of disturbing the variable position adjustment, and there is no problem in use.

[0009]

1 to 4 are perspective views showing an embodiment of a curtain hook according to the present invention. This curtain hook is basically composed of a main body 1, a fastening rod 2, and a hook body 3, and the hook body 3 is a sliding portion that fits in a vertically movable manner with respect to a guide portion formed on the main body 1. 4, a locking rod 5 that is hooked on the curtain runner, and a plurality of downward saw tooth projections 6 formed in the longitudinal direction of the main body 1 are ratchet-type engaged to restrict the movement of the hook body 3. It is constituted by the engaging claw 7.

The main body 1 has a substantially H-shaped cross section having front and rear flanges 8 and 9, and the front flange 8 is formed.
Is used as a guide part on which the sliding part 4 fits and slides, and a plurality of downward saw tooth-shaped projections 6 are formed on the side surface of the main body portion between the front and back side flanged parts 8 and 9. The sliding portion 4 of the hook body 3 that fits into the front side collar-shaped portion 8 has a substantially U-shaped cross-section with both ends bent inward to form opposite hooks 10, and then returned to this hook 10. A locking engagement claw 7 is formed. The central portion of the rear surface of the rear side collar-shaped portion 9 rises in a mountain shape to form a substantially triangular cross section
Increased refraction resistance.

Reference numeral 11 is a pair of horizontal projections projecting horizontally in the upper part of the rear side collar-shaped portion 9, and reference numeral 12 is a vertical projection projecting downward in a slightly lower portion thereof. See also FIG.
Further, in FIG. 4, 13 is a fold formed on the upper end portion of the curtain A, and 14 is a suture thread for forming and holding the fold 13.

When this curtain hook is used, even if the curtain A is hung on the fastening rod 2, the weight of the curtain serves as a force for firmly engaging the engaging claw 7 of the sliding portion 4 with the downward serrated projection 6. Since it works, it does not easily come off during use as in the past.

The present invention is not limited to the above embodiment. Special In this embodiment, the horizontal projection 11 and the vertical projection 12
Was formed, but it does not matter if these are not provided.

[0014]

As described above, since the present invention is a side-engagement type hanging position variable adjustment type plastic curtain hook, the weight of the curtain acts as an engaging force.
The engagement claw of the sliding portion never separates from the downward saw tooth projection of the main body unlike the conventional case. Further, a downward saw tooth projection is formed between the two flange portions of the main body, and the engaging claws engage with each other between the both flange portions, so that the engaging claw and the downward saw tooth projection are caught on the curtain during use. It can be adjusted smoothly without the risk of being caught.

Further, since the main body portion has a substantially H-shaped cross section having a brim portion on the front surface side and the back surface side, it has refracting strength and durability. Further, since the sliding portion is fitted with the front side collar-shaped portion as a guide portion, sliding is smooth, and size reduction is possible unlike the type in which the entire main body portion is held.
