Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to a ring runner used for suspending a curtain on a curtain rail erected on, for example, an upper portion of a window frame.

(B) Conventional technology Since the above-mentioned curtain rails and ring runners are conventionally formed of a metal material such as aluminum, in order to enhance the design value of the entire curtain, painting or plating is applied to the entire outer peripheral surfaces of the curtain rails and ring runners. Etc.

(C) Problems to be solved by the device However, when the curtain is opened and closed many times, the paint and plating applied to the sliding surface between the curtain rail and the ring runner gradually wears and peels off. There is a problem that many scratches, peeling off, etc. are attached to the outer peripheral surface of the curtain rail, and the design value of the entire curtain is impaired.

In addition, the paint or plating applied to the curtain rail and ring runner is peeled off, which reduces the smoothness of the sliding surface and increases the sliding resistance of the ring runner, allowing the curtain to open and close smoothly. In addition to the difficulty, there is a problem that an unpleasant metallic noise is generated when opening and closing.

In view of the above problems, the present invention aims to provide a ring runner capable of preventing the paint or plating from peeling off and smoothly opening and closing the curtain.

(D) Means for Solving the Problems This invention is a metal ring which is slidably inserted on the outer peripheral surface of a rod-shaped curtain rail and which guides opening and closing of the curtain in the length direction of the curtain rail. An annular lubricating member made of a transparent or translucent synthetic resin, which is a runner, and which has a sliding surface on the inner side of the ring runner which makes sliding contact with the outer peripheral surface of the curtain rail, and which is made of a transparent or translucent synthetic resin for smooth sliding with the curtain rail. It is a ring runner fitted with.

(E) Action The ring runner of the present invention is provided, for example, on the inner sliding surface of the ring runner that makes sliding contact with the outer peripheral surface of the curtain rail.
Since an annular lubricating member made of polyethylene resin or Teflon resin is fitted, the lubricating member is interposed between the curtain rail and ring runner to prevent direct contact with the curtain rail when opening and closing the curtain. It At the same time, the sliding resistance with the curtain rail is reduced.

(F) Advantageous Effect of the Invention As described above, according to the present invention, since the lubricating member is fitted on the contact sliding surface of the ring runner with the curtain rail, the lubricating member is interposed between the curtain rail and the curtain member. However, direct contact between the curtain rail and the ring runner can be prevented, and even if the curtain rail is opened and closed, the paint and plating applied to the curtain rail and ring runner can be reliably prevented from peeling off. The overall design value can be maintained for a long time. That is, it is possible to prevent occurrence of inconvenience while maintaining the value of the metal ring runner.

Moreover, due to the interposition of the lubricating member, the sliding resistance between the curtain rail and the outer peripheral surface of the ring runner is reduced, the curtain can be opened and closed smoothly, and the opening and closing means is provided in order to achieve the above-mentioned remarkable effects. Since the lubricating member was fitted only on one side, the ring runner side with a small contact area,
This is more economical than covering the entire outer peripheral surface of the curtain rail with the same kind of lubricating member.

Further, since the lubricating member is formed of the annular synthetic resin, the fitting work can be performed extremely easily due to its material elasticity. Further, since it has an annular shape, a reliable effect can be achieved even if the lubricating member rotates on the sliding surface of the ring runner.

Further, since the lubricating member is transparent or translucent,
It is possible to obtain a predetermined aesthetic appearance without wasting the special coating and plating applied to enhance the design value.

(G) Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

The drawing shows a ring runner used as a guide for opening and closing the curtain. In FIG. 3, many ring runners are inserted and fitted on the outer peripheral surface of a curtain rail 2 which is installed above the window frame (not shown). , Two curtains 3, 3 are suspended from each ring runner 1, which is evenly distributed to the left and right.

As shown in FIGS. 1 and 2, the above ring runners 1 include a ring portion 4 slidably fitted on the outer peripheral surface of a metallic curtain rail 2 formed in a cylindrical shape, and a curtain. The hanging part 5 for hanging 3 is integrally formed of a metal material such as aluminum, and the ring part 4
A lubricating ring 6 made of synthetic resin is fitted to the inner peripheral surface of the above, that is, the sliding surface 4a that makes sliding contact with the outer peripheral surface of the curtain rail 2.

The ring portion 4 described above is formed to have a diameter slightly larger than the outer diameter dimension of the curtain rail 2.

The above-mentioned hanging portion 5 is formed with a locking hole 5a for hanging a hook (not shown) locked at the upper edge of the curtain 3.

The lubricating ring 6 is integrally formed of transparent or translucent synthetic resin such as polyethylene resin or Teflon resin,
Moreover, the sliding surface 4a of the ring portion 4 formed on the ring runner 1
It is formed in a ring shape that can be fitted to.

Assuming that the illustrated embodiment is configured as described above, the operation and operation will be described below.

When the curtains 3, 3 using such a ring runner 1 are opened and closed in the direction of the arrow as shown in FIG. 3, the ring runner 1 slides in contact with the outer peripheral surface of the curtain rail 2 and slides on the ring runner 1. By covering the surface 4a with a lubrication ring 6 formed of polyethylene resin, the lubrication ring 6 is interposed between the curtain rail 2 and the ring runner 1 when the curtains 3, 3 are opened and closed so that the curtain ring 2 and the curtain rail 2 directly Contact, and at the same time, the sliding resistance with the curtain rail 2 is reduced.

Therefore, since the sliding surface 4a of the ring runner 1 that contacts the curtain rail 2 is covered with the lubricating ring 6, the lubricating ring 6 is interposed between the curtain rail 2 and the curtain rail 2 and the ring runner 1. Direct contact with the curtain rail 2 even if the curtains 3 and 3 are opened and closed.
Also, it is possible to reliably prevent the paint or plating applied to the ring runner 1 from peeling off, and the design value of the curtains 3, 3 as a whole can be maintained for a long period of time.

Moreover, due to the interposition of the lubricating ring 6, the sliding resistance between the curtain rail 2 and the outer peripheral surface of the ring runner 1 is reduced,
Since the curtains 3 and 3 can be opened and closed smoothly and the remarkable effect as described above is exhibited, the lubricating ring 6 is fitted only on one side of the opening and closing means, which side has a small contact area. This is more economical than forming the same type of lubricating member over the entire outer peripheral surface of the curtain rail 1.

Moreover, since the lubricating ring 6 is formed of an annular synthetic resin,
The fitting operation can be performed extremely easily due to the elasticity of the material.
Moreover, since it is annular, even if the lubricating ring 6 rotates on the sliding surface 4a of the ring runner 1, a reliable effect can be achieved.

Further, since the lubricating ring 6 is formed transparent or semi-transparent, the design value due to the coating or plating applied to the ring runner 1 is not impaired.
