Abstract

PROBLEM TO BE SOLVED: To reduce the cost by dispensing with cutting after the main body is molded, and not to be restricted by material quality in respect of a fusing point by integrally molding the projecting and recessed parts of the main body with the main body. SOLUTION: A ring runner 1 for a curtain pole is formed by a main body 2 and an inner ring 6. The main body 2 is formed by resin excellent in appearance formation, and formed by an annular part 3 where a curtain pole is inserted and a locking part 5 for locking a curtain hook. An annular projection (projecting and recessed parts) 4 is formed on the inner peripheral surface of the annular part 3. The projection 4 is molded integrally with the main body 2 at the time of molding the main body 2. The inner ring 6 is shaped so that a part of the annular portion is notched. An annular groove 7 is formed on the outer peripheral surface of the inner ring 6, and a sliding surface 8 having a semicircular sectional outline is formed on the inside. The inner ring 6 is molded by resin good in sliding performance and elasticity.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring runner for a curtain pole, and more particularly, to a ring runner for a curtain pole made of a resin which requires decorative properties.

[0002]

2. Description of the Related Art Conventional ring runners for curtain poles,
In particular, a ring runner for a resin curtain pole that requires decorativeness is, for example, molded with a resin having an excellent appearance to form the main body in order to have both decorativeness and sliding properties. Is cut to form a groove, and a ring made of a highly slidable resin is fitted into the groove to produce the groove. Alternatively, a resin ring having excellent sliding properties is molded as an insert, and the main body is integrally formed with the resin ring by insert molding with a resin having excellent appearance.

[0003]

However, the above-mentioned conventional ring runner is manufactured by cutting the inner peripheral surface of the annular portion of the main body to form a groove, and fitting a resin ring having a high sliding property into the groove. In the case of (1), there is a problem that a great deal of labor and time are required for cutting the groove, resulting in an increase in cost.
In the case of a ring runner manufactured by insert-molding the main body integrally with the resin ring, use a resin whose ring melting point is higher than the melting point of the main body so that the resin ring does not melt during the molding of the main body. There is a problem of having to choose.

The present invention has been made to solve such a problem, and an object of the present invention is to reduce the cost by eliminating the need for cutting after the main body is formed.
It is an object of the present invention to provide a curtain pole ring runner which is not restricted by the material in terms of melting point.

[0005]

In order to solve the above-mentioned problems, a ring runner for a curtain pole according to the present invention comprises a resin body having an annular concave and convex portion on the inner peripheral surface or the outer peripheral surface of the annular portion; And a resin fitting member which has a partially cut-out shape and is elastically fitted into or out of the uneven portion of the resin body, respectively, and the uneven portion of the body is molded integrally with the main body. . This eliminates the need for cutting the uneven portion provided on the annular portion of the main body.

In this means, when the fitting member is fitted inside the main body, the fitting member is molded with a resin having excellent sliding properties, and the main body is molded with a resin excellent in appearance. When the fitting member is externally fitted to the main body, the fitting member is molded with a resin having excellent appearance, and the main body is molded with a resin having excellent sliding properties.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a ring runner for a curtain pole according to the present invention will be described below in detail with reference to FIGS. FIG. 1 shows a curtain pole ring runner 1 of the present invention, which comprises a main body 2 and an inner ring (fitting member) 6. The main body 2 is made of a resin excellent in appearance and has an annular portion 3 through which a curtain pole is inserted.
And a locking portion 5 for locking the curtain hook. As shown in FIGS. 1 and 2, an annular projection (an uneven portion) 4 is formed on the inner peripheral surface of the annular portion 3. The projection 4 is formed integrally with the main body 2 when the main body 2 is formed. As shown in FIG. 1, the inner ring 6 has a shape in which a part of an annular shape is cut out. As shown in FIGS. 1 and 2, an annular groove 7 is formed on the outer peripheral surface of the inner ring 6, and a sliding surface 8 having a semicircular cross-sectional shape is formed inside. The inner ring 6 is formed of a resin having excellent sliding properties and elasticity.

[0010] The elasticity of the inner ring 6 is used to make the groove 7
Is fitted to the projection 4 of the main body 2, and the inner ring 6 is internally fitted to the annular portion 3 of the main body 2. Thus, the curtain pole ring runner 1 is completed.

[0009]

A second embodiment of a ring runner for a curtain pole according to the present invention will be described below in detail with reference to FIGS. FIG. 3 shows the curtain pole ring runner 11 of the present invention, which comprises a main body 12 and an outer ring (fitting member) 17. The main body 12 is made of a resin having excellent sliding properties, and has an annular portion 13 through which a curtain pole is inserted.
And a locking portion 15 for locking the curtain hook. FIG.
As shown in FIG. 4, an annular groove (irregular portion) 14 is formed on the outer peripheral surface of the annular portion 13. This groove 14 is
Is molded integrally with the main body 12 at the time of molding. Annular part 1
A sliding surface 16 having a semi-circular cross-sectional profile is formed inside 3. As shown in FIG. 3, the outer ring 17 has a shape in which a part of a ring is cut out, and is formed from a resin having excellent appearance and excellent elasticity.

By utilizing the elasticity of the outer ring 17, the outer ring 17 is fitted into the groove 14 of the main body 12 and fitted on the annular portion 13. Thus, the curtain pole ring runner 11 is completed.

[0011]

As described above in detail, the ring runner for a curtain pole according to the present invention has a resin main body having an annular concave and convex portion on the inner peripheral surface or the outer peripheral surface of the annular portion, and a circular annular portion. It has a chipped shape and is made of a resin fitting member that is elastically fitted into or out of the concave and convex portions of the resin main body, and the concave and convex portions of the main body are integrally molded with the main body. Since cutting work is not required, cost can be reduced, and there is an excellent effect that there is no material limitation in terms of melting point because insert molding is not performed.
