Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement of a so-called adjuster type plastic curtain hook that can variably adjust the hanging height of the curtain.

[Conventional technology]

A conventional curtain hook of this type includes one shown in FIG. 4, for example. That is, the main body part 10 has the curtain fastening rod 9 on the back side.
A hook body 12 having a locking rod 11 for securing to the curtain runner is slidably assembled at a sliding portion 13, and a downwardly serrated projection 14 that engages a detent engagement pawl provided on the hook body 12 is attached to the main body. This configuration is formed on the back surface of the section 10. Therefore, variable adjustment of the height position is usually performed by sliding the sliding portion 13, and fixation of the position is achieved by engaging the engaging claw with the protrusion 14.

[Problem that the invention attempts to solve]

By the way, due to the unique reason that conventional curtain hooks of this kind are made of plastic, the fastening rods 9 often deform when used, compared to ordinary wire rod type curtain hooks, which causes the curtain to deteriorate. Since the suspended state becomes unstable, it is not only inappropriate from a decorative point of view, but also has the inherent difficulty that the fastening rod, which has been firmly fixed, is likely to come off.

Therefore, the purpose of this invention is to prevent as much as possible the deformation of the fastening rods that occurs when opening and closing the curtains, to stabilize the suspended state of the curtains, and to
To provide a curtain hook made of plastic that does not hinder decoration and is particularly difficult to fall off.

[Means for solving problems]

In order to solve this problem, this invention adopts the following technical means.

In other words, the fundamental reason why the fastening rods are easily deformed and easily separated is that the force applied to the fastening rods when opening and closing the curtain is not directly transmitted to the main body, but is transmitted to the main body through the lower end of the fastening rod. For this reason, this invention adopts a structure in which angular horizontal protrusions are formed on the back surface of the main body portion in a substantially bifurcated manner in opposite directions in the horizontal direction.

[Effect]

Therefore, while the fastening rod plays the original role of fastening to the curtain, the main body itself can also be fixed directly to the curtain fabric, so when opening and closing the curtain, only the fastening rod acts on the curtain hook. It spreads directly to the main body without being biased towards the other side, and becomes integrated with the curtain, so to speak. Therefore, the fastening rod will not be deformed and will never come off from the curtain.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of the curtain hook according to the invention, FIG. 2 is a plan view showing the curtain hook in use, and FIG. 3 is a perspective view thereof. In the figure, 1 is a main body part, and 2 is a fastening rod to the curtain that is located on the back side of the main body part and rises from the lower end in a substantially vertical direction. Reference numeral 3 designates a hook body having a sliding portion 4 that is slidable relative to the main body portion 1, and has a locking rod 5 that is continuously formed from the sliding portion 4 and is connected to a curtain runner.

Reference numeral 6 designates downward serrated projections constituting the back surface of the main body 1, and is configured to engage with the sliding portion 4 of the hook body 3 described above. Note that this downward serrated projection 6 has a reinforcing portion 7 having a substantially triangular cross section on its back surface.
are integrally formed, and together with the downward serrated projections 6, provide a reinforcing effect to the entire main body portion 1.

On the other hand, reference numeral 8 denotes a angular projection formed on the back surface of the main body portion 1, and in this embodiment, in particular, horizontal projections 8a, which protrude approximately bifurcated in opposite directions in the horizontal direction from the upper end portion of the back surface of the reinforcing portion 7; 8b is formed, and a vertical projection 8c projecting downward is formed somewhat below the horizontal projection. Note that 15 is a curtain tack formed by folding back and sewing the upper end of the curtain 16, 17 is a fold for inserting a curtain hook, and 18 is a sewing thread for forming and holding the fold 17. It is.

Therefore, this curtain hook is
As shown in the figure, when the fastening rod 2 is inserted into the fold 17 of the curtain tuck 15, the curtain hook is fixed to the curtain 16 by the fastening rod 2, while the vertical protrusion 8c formed on the back surface of the main body 1 The horizontal protrusions 8a and 8b are caught on the curtain material, and the main body portion 1 is also directly fixed to the curtain 16. In particular, the horizontal protrusion 8 of this embodiment
a and 8b, because the reinforcing part 7 has a substantially triangular cross section, when the fastening rod 2 is fastened to the curtain tack 15, the reinforcing part 7 is relatively fitted to the curtain tack 15, and is horizontal. The protrusions 8a and 8b are hooked on the curtain fabric, and can further prevent the main body from lateral deformation.

Although the angular protrusions 8 are formed relatively at the upper end of the back surface in the embodiment, they are of course not limited to this, and can be formed at any position where the main body 1 can be fixed to the curtain fabric. No problem. However, from the standpoint of preventing lateral deformation as much as possible and facilitating the removal of the curtain hook itself, both the horizontal protrusions 8a and 8b and the vertical protrusion 8c are relatively close to the upper end of the back surface of the main body 1. It is preferable to form the

Also, in this embodiment, the angular protrusion 8 is formed separately into horizontal and vertical protrusions, but these are combined and integrated to prevent deformation or movement in either the horizontal or vertical direction. Needless to say, any structure can be adopted, and in short, any configuration can be adopted as long as the main body portion 1 is fixed to the curtain fabric.

Furthermore, the direction in which the horizontal protrusions 8a and 8b protrude may be determined depending on the type of fastening such as tack.

In this embodiment, the angular protrusion 8 is formed on the reinforcing part 7 of the main body part 1, but it goes without saying that the present invention can also be applied to a curtain hook without a reinforcing part.
Further, in this embodiment, the downward serrations are formed on the main body 1.
Although the explanation has been made by taking as an example a curtain hook that is configured on the back side of the curtain hook, the curtain hook may be configured on the front side of the curtain hook, and is not particularly limited.

[Effect of idea]

As described above, this invention forms angular horizontal protrusions on the back of the main body of the curtain hook that protrude in approximately bifurcated directions in opposite directions in the horizontal direction, so that the curtain hook is integrated with the curtain in all parts. This makes it possible to completely match the movement of the curtain, and it can follow any opening/closing movement of the curtain, preventing undesirable deformation or detachment. We were able to provide a curtain hook that eliminates all the drawbacks.
