Unexamined-Japanese-Patent No. 2004-230153 Japanese Patent Application Laid-Open No. 11-137416

  However, in the inventions of Patent Documents 1 and 2, since the thickness of the ring runner main body in the central axis direction of the hole of the ring is uniform over the entire circumference, when the ring runner is passed through the curtain rail It shakes quickly. Therefore, the operation of hooking the curtain hook attached to the curtain to the curtain attachment portion is complicated.

  The present invention has been made from such a point of view, and an object of the present invention is to provide a ring runner that can make the swing slower than before.

  In order to solve such problems, the present invention is an annular ring runner having an insertion hole through which a curtain rail is inserted, and the thickness of the ring runner in the central axis direction of the insertion hole is greater than that of the upper part It is characterized in that the lower portion is formed large.

  According to the present invention, the center of gravity of the ring runner is lowered, and the separation distance from the rocking fulcrum at the top to the center of gravity can be increased, so that the ring runner can be slowed in its swing (the swing cycle can be increased). . This makes it easy to hook the curtain hook on the ring runner.

  Moreover, it is preferable that the thickness of the said ring runner in the central axis direction of the said penetration hole is formed so large that it goes to a lower part.

  According to this configuration, since the outer shape of the ring runner is expanded toward the lower part, the overall design of the ring runner can be changed to improve the design.

  In addition, it has an annular ring runner main body, and a curtain attachment portion attached to the lower portion of the ring runner main body and to which a curtain is attached, and an attachment hole to which the curtain attachment portion is attached is provided in the lower portion of the ring runner main body. Preferably, the ring runner main body has a center of gravity in the lower half including the mounting hole.

  According to this configuration, the center of gravity of the ring runner main body can be lowered even if the mounting hole for mounting the curtain mounting portion is formed in the lower portion of the ring runner main body.

  Preferably, the curtain mounting portion snap-fits into the mounting hole.

  According to this configuration, the mounting work of the curtain mounting portion to the ring runner main body can be easily performed.

  According to the ring runner of the present invention, shaking can be made slower than in the prior art.

<Curtain attachment part>
The curtain attaching portion 32 is a portion to which the draped curtain C is attached. The curtain attachment portion 32 is formed of, for example, a functional and versatile resin. The curtain attachment portion 32 may be formed of metal. The curtain attachment portion 32 is configured of an insertion portion 32 a and an annular portion 32 b that protrudes annularly downward from the lower end of the insertion portion 32 a. The curtain attachment portion 32 is fixed to the runner outer 33 by a snap fit that elastically engages (fits) the insertion portion 32a with the attachment hole 33a. The curtain mounting portion 32 is rotatably mounted around a vertical axis around the insertion portion 32a.

  The insertion portion 32a is a portion inserted from below into the mounting hole 33a, and has a shape in which two truncated cones are vertically connected. The outer diameter of the insertion portion 32a is substantially equal to the inner diameter of the mounting hole 33a.

  The annular portion 32 b is an annular portion to which a curtain hook (not shown) attached to the upper edge of the drape curtain C is hung. In the annular portion 32b, a disc-like collar portion 32c having a diameter larger than that of the insertion portion 32a is formed at the boundary with the insertion portion 32a. The outer diameter of the collar portion 32c is larger than the inner diameter of the mounting hole 33a.

Here, with reference to FIG. 4, the thickness T1 of the ring runner main body 31 and the thickness T2 of the curtain attachment portion 32 in the central axis direction of the insertion hole 35 will be described.
The thickness T1 of the ring runner main body 31 (runner outer 33) is formed to be larger toward the lower portion 3A (closer to the curtain attachment portion 32). Lower part 3 of the ring runner main body 31
The thickness T1a of A is formed larger than the thickness T1b of the upper portion 3B (T1a> T1b). In other words, the longitudinal cross-sectional area of the portion excluding the mounting hole 33a in the lower portion 3A is formed larger than the longitudinal cross-sectional area of the upper portion 3B in a longitudinal cross-sectional view along the rail longitudinal direction. The ring runner main body 31 has a center of gravity on the lower portion 3A side (lower half) including the mounting hole 33a.

  In the curtain attachment portion 32, the thickness T2 of the annular portion 32b exposed from the ring runner main body 31 is formed to be larger toward the center from the collar portion 32c. The thickness T2a of the flange portion 32c is formed to be substantially equal to the thickness T1a of the lower portion 3A of the ring runner main body 31. Thereby, when the ring runner 3 is seen from the room, since the external shape of the ring runner main body 31 and the curtain attaching part 32 is seen continuously, the high designability with a sense of unity can be produced. In the present embodiment, the thickness T2 of the annular portion 32b is formed larger as it goes from the flange portion 32c to the vicinity of the center, but the thickness T2 may be appropriately changed without being limited to such a shape.

The thickness T1a of the lower portion 3A of the ring runner main body 31 is larger than the thickness T1b of the upper portion 3B (T1a> T1b). In other words, the longitudinal cross-sectional area of the portion excluding the mounting hole 33a in the lower portion 3A is formed larger than the longitudinal cross-sectional area of the upper portion 3B in a longitudinal cross-sectional view along the rail longitudinal direction. The ring runner main body 31 has a center of gravity on the lower portion 3A side (lower half) including the mounting hole 33a. Also according to this modification, the same function and effect as those of the embodiment can be obtained.

  Moreover, you may use the square-ring-shaped ring runner main body 31 shown to Fig.6 (a). In the modification shown to Fig.6 (a), the ring runner main body 31 has four sides extended linearly in a side view.

  As shown in FIG. 6 (b), the thickness T1 of the ring runner main body 31 in the central axis direction of the insertion hole 35 becomes smaller from the upper portion 3B to the lower side, It has become. Further, the thickness T1 of the ring runner main body 31 is larger as it goes downward from the thin portion 3C, and the lower portion 3A is the largest. That is, the thickness T1a of the lower portion 3A, the thickness T1b of the upper portion 3B, and the thickness T1c of the thin portion 3C have a relationship of T1a> T1b> T1c. In other words, the longitudinal cross-sectional area of the portion excluding the mounting hole 33a in the lower portion 3A is formed larger than the longitudinal cross-sectional area of the upper portion 3B in a longitudinal cross-sectional view along the rail longitudinal direction. The ring runner main body 31 has a center of gravity on the lower portion 3A side (lower half) including the mounting hole 33a. Also according to this modification, the same function and effect as those of the embodiment can be obtained.

  Moreover, in this embodiment, although the ring runner 3 was provided with the curtain attachment part 32, and it was set as the structure which hooks the curtain hook of the drape curtain C on the curtain attachment part 32, this invention is not limited to this. For example, the curtain attachment portion 32 may be omitted, and the curtain hook may be directly hooked to the ring runner main body 31.
