(First embodiment)
An embodiment of a ring runner embodying this invention will be described below with reference to the drawings. As shown in FIG. 1, the curtain rail 11 is formed in a round bar shape with metal, both ends are supported by brackets 12, and the brackets 12 are fixed to the mounting surface. A decorative terminal member 13 is attached to both ends of the curtain rail 11.

  A large number of ring runners 14 are movably supported between the brackets 12 on the curtain rail 11, and one end runner 15 is supported between each bracket 12 and the terminal member 13. The ring runner 14 and the end runner 15 are runners having the same configuration.

  Next, a specific configuration of the ring runner 14 will be described with reference to FIGS. The ring runner 14 includes an outer ring 16 formed in an annular shape with a metal that is harmoniously designed with the curtain rail 11, and an inner ring 17 that is fitted on the inner peripheral side of the outer ring 16.

  The inner ring 17 is formed of a synthetic resin into an annular shape having an opening 17a, and an outer ridge 18a is formed on the outer peripheral surface in the circumferential direction. On the inner peripheral surface of the outer ring 16, a recess 19 that allows the outer protrusion 18 a to be fitted is formed. Then, the inner ring 17 is bent and inserted into the outer ring 16, and when the outer protrusion 18 a of the inner ring 17 is fitted into the recess 19 of the outer ring 16, the inner ring 17 is moved to the inner peripheral side of the outer ring 16. Retained. In this state, the inner peripheral surface of the outer ring 16 is covered with the inner ring 17.

  Inner ridges 18b are formed on the inner peripheral side of the inner ring 17 so as to be in sliding contact with the curtain rail 11, and oval insertion holes 20 are formed between the inner ridges 18b. The opening 17a is located on the shaft. The short diameter of the insertion hole 20 is smaller than the diameter of the termination member 13.

  The outer ring 16 is provided with a mounting hole 22 for attaching a hook hook 21. The mounting hole 22 is formed so as to penetrate the outer ring 16 in the radial direction, and the inner ring 17 is fitted so that the mounting hole 22 is exposed at the opening 17a.

  A hook hook 21 is inserted into the mounting hole 22 from the inside of the outer ring 16, and a hook ring 23 is attached to the tip of the hook hook 21 exposed to the outer peripheral side of the outer ring 16. The base end portion of the hook hook 21 is formed in a lid shape that covers the inner peripheral surface of the outer ring 16 around the attachment hole 22 between the openings 17a.

  In order to install the curtain rail 11 using the ring runner 14 and the end runner 15 configured as described above, the curtain rail 11 is inserted into the insertion holes 20 of the ring runner 14 and the end runner 15, and then both ends of the curtain rail 11 are installed. The end member 13 is attached to the end.

  Next, the curtain rail 11 is attached to the bracket 12 fixed to the attachment surface in advance. At this time, the end runner 15 is positioned between the end member 13 and the bracket 12.

  Thus, in the state where the curtain rail 11 is attached to the bracket 12, even if the ring runner 14 and the end runner 15 are inclined as shown in FIG. 4, the shape of the insertion hole 20 of the internal ring 17 and the hook hook 21 As shown in FIG. 2, the hook ring 23 is automatically rotated to a state in which the hook ring 23 is suspended and supported by the weight of the hook ring 23.

Moreover, since the short diameter of the insertion hole 20 of the end runner 15 is smaller than the diameter of the termination member 13, the end runner 15 is held between the termination member 13 and the bracket.
If the curtain fabric is suspended and supported on the hook ring 23 of the ring runner 14 and the end runner 15, the curtain fabric is suspended and supported so as to be movable along the curtain rail 11.

  As shown in FIG. 3, the ring runner 14 that suspends and supports the curtain fabric is always held in the vertical direction, and is in contact with the curtain rail 11 by the internal ring 17. Even when the ring runner 14 is inclined in the moving direction with respect to the curtain rail 11 as shown in FIG. 5 during the movement of the curtain fabric, the contact between the curtain rail 11 and the outer ring 16 is caused by the inner protrusion 18b and the hook hook 21. Is prevented.

  Moreover, even if the ring runner 14 is inclined in the left-right direction, as shown in FIG. Therefore, the curtain rail 11 and the outer ring 16 do not come into contact with each other.

With the ring runner configured as described above, the following operational effects can be obtained.

(2) The contact between the outer ring 16 and the curtain rail 11 can be prevented when the curtain fabric is moved.
(3) Since the inner ring 17 in contact with the curtain rail 11 is formed in an annular shape having an opening 17a, it can be easily fitted inside the outer ring 16.
(4) Since the outer ring 16 is covered with the hook hook 21 formed of synthetic resin in the opening 17a of the inner ring 17, contact between the curtain rail 11 and the outer ring 16 can be prevented in the opening 17a.
(5) Since the insertion hole 20 between the inner ridges 18b has an oval shape, the opening 17a is positioned on the long axis of the ellipse, and the hook hook 21 is positioned in the opening 17a, the ring runner 14 The center of gravity can be eccentric to the hook hook 21 side. Therefore, when the curtain fabric is not operated, the ring runner 14 can be automatically rotated so that the hook hook 21 is positioned downward.
(6) Since the insertion hole 20 between the inner ridges 18b is always in the shape of an ellipse in the vertical direction, it is necessary to ensure a sufficient allowable tilting angle in the traveling direction of the ring runner 14 when the curtain fabric is moved. Can do. Therefore, the sliding performance of the ring runner can be ensured.
(7) Since the short diameter of the insertion hole 20 of the inner ring 17 is made smaller than the outer diameter of the termination member 13, the end runners 15 at both ends of the curtain rail 11 and the ring runners 14 at the intermediate part of the curtain rail 11 are made common. Can do. Therefore, the number of parts can be reduced.
