However, when the conventional curtain hook 400 is used, there is a problem that the upper part of the curtain is inclined forward with respect to the curtain body as shown in FIG. This is because, when the curtain hook 400 is inserted into the curtain fixing portion, the hook 451 portion locked to the curtain runner 310 and the substantially U-shaped curved portion 420 supporting the curtain fixing portion end surface This is because the curtain hook 400 is rotated so that the substantially U-shaped curved portion 420 is pulled in the vertically downward direction of the hook 451.
For this reason, when the conventional curtain hook 400 is used, the appearance of the upper part of the curtain is deteriorated, and a gap is widened between the curtain rail 300 and the upper part of the curtain, which is not preferable from the viewpoint of soundproofing, light shielding, and indoor heat insulation. The curtain hook according to the present invention solves these problems.

The curtain hook according to the present invention is an insertion rod to be inserted and attached to the fastening portion of the curtain,
A main rod that is connected to the insertion rod via a substantially U-shaped curved portion;
A hook body that is hooked to the curtain runner at the upper portion and a claw portion at the lower portion, and that is connected to the main rod,
In curtain hooks having
The principal consists of a first principal and a second principal,
The first main rod is connected to the insertion rod via a substantially U-shaped curved portion,
The second main rod is connected to the first main rod at an angle with respect to the first main rod,
It is a ratchet structure which can engage the claw part of the hook body with the engagement projection formed in the surface opposite to the paper surface perpendicular direction of the 2nd main fence.

  Preferably, the first main rod has a ratchet structure in which a hook portion of the hook body can be engaged with an engaging protrusion formed on the front surface and / or the back surface of the first main rod.

  Further preferably, the first main rod has a fin portion facing the insertion rod and formed from the first main rod along the second main rod and the substantially U-shaped curved portion. The fin portion has a smaller cross section than the first main rod.

  Also preferably, it has a hook-shaped ten-hand portion projecting in the direction of the insertion rod from the upper portion of the fin portion and / or the upper portion of the first main rod.

  Preferably, an angle between the first main rod and the second main rod is 35 to 65 degrees.

  Further preferably, an angle between the first main rod and the second main rod is 40 to 50 degrees.

  In the curtain hook according to the present invention, the main rod is composed of the first main rod and the second main rod, and the first main rod is continuously provided via the insertion rod and the substantially U-shaped curved portion. The rod is connected to the first main rod at an angle with respect to the first main rod. Therefore, the hook can be positioned above the substantially U-shaped curved part that supports the curtain fastening part end face. Therefore, since the vertical displacement between the hook portion locked to the curtain runner and the substantially U-shaped curved portion is reduced, the curtain hook becomes difficult to rotate and the forward tilt of the curtain upper portion is suppressed. Can do.

  If the forward tilt of the upper part of the curtain is suppressed, the upper part of the curtain becomes closer to the vertical, so that the appearance can be improved. In addition, the light shielding effect is improved by narrowing the gap between the curtain upper portion and the curtain rail. Similarly, when the gap between the curtain upper portion and the curtain rail is narrowed, the area into which the outside air directly flows is narrowed, and the indoor warming effect is improved. Similarly, since the space between the curtain upper part and the curtain rail is narrowed, the area in which external sound is propagated in the air is narrowed, so that the indoor soundproofing effect is improved.

Furthermore, the curtain hook according to the present invention can be used for the so-called B suspension as long as the first main rod can be engaged with the claw portion of the hook body and the hook body is engaged with the first main rod. Can do.
In general, there are two ways of hanging the curtain from the runner: A hanging and B hanging. A-hanging is a method of hanging so that the height of the upper edge of the curtain is substantially coincident with the height of the lower end of the runner. How to hang.

  Further, since the fin portion is present, the fixing portion of the curtain can be sandwiched between the insertion rod and the fin portion, and the curtain can be stably supported. Further, by making the fin portion thinner than the first main rod, the curtain fixing portion can be easily inserted into the insertion rod. In addition, by reducing the thickness of the fin portion, the curtain and the curtain hook are less likely to slip because the fin is firmly inserted into the curtain even after the insertion rod is inserted. Further, since the plate thickness is thin, the resin material can be reduced and the cost can be suppressed.

As shown in FIG. 7, in the conventional curtain hook, in the natural state where the curtain hook is suspended from the curtain runner, the vertical inclination of the curtain hook is 10.16 degrees. Therefore, it is necessary to correct the inclination of at least 10.16 degrees.
In the curtain hook according to the present invention, this inclination is corrected by the angle (shown in FIG. 8) between the first main rod and the second main rod. If the angle between the first main rod and the second main rod is less than 10.16 degrees, the curtain hook itself is in a forward tilted posture, and it is difficult to realize the effect. Further, if the angle between the first main rod and the second main rod is greater than 90 degrees, it may be difficult for the hook to be locked to the curtain runner, and the function of the curtain hook may be impaired.
Therefore, if the angle between the first main rod and the second main rod is 10.16 to 90 degrees, the vertical inclination of the curtain hook can be corrected and the hook can be properly locked to the curtain runner. can do. Also, even if the shape and dimensions of the adjuster hook change to some extent, the angle between the first main rod and the second main rod is 35 in order to secure the vertical adjustment width by the adjuster and to suppress the tilt of the upper part of the curtain. -65 degrees is preferred.

  Furthermore, if the angle between the first main rod and the second main rod is 40 to 50 degrees, the hook is positioned substantially above the end surface of the curtain fastening portion while ensuring the vertical adjustment range by the adjuster. Since it becomes easy, inclination of the curtain upper part can be suppressed more.

  The curtain hook 100 in FIG. 1 includes an insertion rod 10, a first main rod 31 that is connected to the insertion rod 10 via a substantially U-shaped curved portion 20, and a substantially U-shape in the first main rod 31. The second main rod 32 is provided on the other end side continuous with the curved portion 20, and the hook body 50 is engaged with the second main rod 32.

  The insertion rod 10 is intended to be inserted into the fastening portion of the curtain 200, and after being inserted into the fastening portion of the curtain 200, the curtain 200 is mainly supported by the insertion rod inner surface 11. Further, if the free end 12 of the insertion rod 10 is warped back to the opposite side to the first main rod 31, the insertion rod 10 can be easily inserted into the fastening portion of the curtain 200.

  The main rod 30 includes a first main rod 31 and a second main rod 32. As shown in FIG. 4, the second main rod 32 has a substantially H-shaped cross section having flange portions 32 a and 32 b in the front and rear, and a plurality of downward projections 32 c are continuously formed on the back surface of the front flange portion 32 a. Yes. The claw portion 52 is mounted so as to hold the front collar portion 32a, has a claw that engages with the downward projection 32c in a ratchet manner, and is slidably mounted only downward. This configuration is known as an adjuster type hook.

  The fin portion 40 is disposed between the first main rod 31 and the insertion rod 10, and supports the curtain 200 when the insertion rod 10 is inserted into the fastening portion of the curtain 200. Specifically, it is formed along the first main rod 31 to the second main rod 32 and the substantially U-shaped curved portion 20 while facing the insertion rod 10. If the fin inner surface 41 is formed so that the absolute value of the angle between the fin inner surface 41 and the insertion flange inner surface 11 is 0 ° to 10 °, the fastening portion of the curtain 200 is inserted into the insertion rod 10. It becomes easy and it becomes easy to support the curtain 200 even after insertion.

  In addition, as shown in FIG. 2, the fin portion 40 is formed to have a thickness smaller than that of the first main rod 31. By making the fin portion 40 thinner than the first main rod 31, the fastening portion of the curtain 200 can be easily inserted into the insertion rod 10. Further, by reducing the thickness of the fin portion 40, the curtain 200 and the curtain hook 100 are not easily displaced because the fin 200 is firmly inserted into the curtain 200 even after the insertion rod 10 is inserted. Further, since the plate thickness is thin, the resin material can be reduced and the cost can be suppressed. Considering the ease of insertion into the insertion rod 10 with respect to the fastening part of the curtain 200 and the strength of the fin part 40, the plate thickness of the fin part 40 is preferably 1 mm to 5 mm. More preferably, it is 2 mm-4 mm.

  The hook body 50 includes a hook 51 and a claw portion 52 that are engaged with the curtain runner 310. As described above, the claw portion 52 engages with the downward projection 32c in a ratchet manner.

  Next, the curtain hook in the second embodiment of the present invention will be described. FIG. 9 shows a curtain hook in the second embodiment of the present invention.

  As shown in FIG. 9, the curtain hook 101 of the second embodiment is a curtain hook in which a tenth portion 60 is further formed on the curtain hook 100 of the first embodiment. The tenth hand part 60 is formed in a hook shape protruding from the upper part of the fin part 40 in the direction of the insertion hook 10. The ten-handed portion 60 can support the curtain 200 by being inserted into the fastening portion of the curtain 200 in the same manner as the insertion rod 10. Since the curtain 200 can be supported by the insertion rod 10 and the ten-handed portion 60, the insertion rod 10 can be prevented from being elastically deformed in the direction opposite to the main rod 30 due to the weight of the curtain. If the insertion rod 10 is elastically deformed, the center of gravity of the curtain hook 101 is changed accordingly, and the curtain hook 101 is inclined forward. The presence of the ten-handed portion 60 can prevent elastic deformation of the insertion rod 10 and prevent the curtain hook 101 from being tilted forward. The ten-handed portion 60 is formed not only from the upper portion of the fin portion 40 but also from the upper portion of the first main rod 31 or from the upper portion of the fin portion 40 and the first main rod 31 in the direction of the insertion rod 10. Also good. Moreover, workability at the time of inserting in a curtain fastening part can be improved by making the hook-shaped front-end | tip of the ten hand part 60 warp to the opposite side to the 1st main rod 31. FIG. When using the curtain hook 101 in which the ten-handed portion 60 is formed, it is necessary to separately form an insertion port for inserting the tenth-handed portion 60 in the fastening portion of the curtain 200.
