DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to a curtain rail with improved mobility wooden ring runner is slidably fitted into a tree Pall.

[0002]

2. Description of the Related Art The walls of living spaces such as houses, offices, restaurants, coffee shops, and classrooms are provided with light and ventilation in consideration.
There are various windows such as high waist windows, bay windows and sweep windows. And these windows have privacy protection,
Curtains are generally hung from the viewpoint of enhancing the livability such as light-shielding properties, sound-insulating properties, and cooling and heating effects. or,
These curtains are also a major factor in impressing the design features of the target living space.

[0003] Therefore, curtains suspended from these windows are replaced with seasonal ones whose colors, patterns, materials, etc. are carefully selected according to the use and atmosphere of each living space, and the living space is utilized. The user opens and closes these curtains according to the situation inside and outside at the time of the operation.

[0004] By the way, as shown in FIG. 7, a kind of curtain rail for suspending the curtain so as to freely open and close the curtain includes a round bar-shaped wooden pole 1 and a plurality of relatively large wooden ring runners of the same quality as the wooden pole. 2 are movably fitted, and an upper edge of a curtain (not shown) is hung on these ring runners 2.

[0005] A curtain rail using such a wooden pole 1 can enhance the atmosphere of the target living space by matching the texture of the wooden pole 1, which is a natural material, with the walls, window frames, curtain fabric, and the like that constitute the living space. A synergistic effect can be expected to relax naturally.

[0006]

However, a curtain rail using such a wooden pole 1 has a design effect that the atmosphere of a living space can be more naturally relaxed, but the curtain is opened and closed. There is also a drawback that the movement of the ring runner 2 at the time may not be performed smoothly.

The cause of such a problem is that the wooden pole 1 and the wooden ring runner 2 have a long mutual contact portion along the circumferential direction as shown in the sectional view of FIG.
In addition, since the frictional resistance is large due to the material, the sliding resistance is increased.

If the pole 1 or the ring runner 2 contains moisture or the sliding surface becomes rough due to aging, the sliding resistance rises. The sliding contact surface between the pole 1 and the ring runner 2 wears due to the use over time, and irregularities are generated, and the sliding resistance increases. Can be considered.

[0009] The influence of the above-mentioned problems becomes greater as the mounting position of the curtain rail becomes higher and the hanging curtain becomes longer and its weight increases. In order to solve these problems caused by the combination of the wooden pole and the wooden ring runner, there is, for example, an invention described in Japanese Patent Application Laid-Open No. 9-224813.

According to the present invention, a guide means such as a guide groove is provided along the length of the wooden pole, and a runner member such as a guide roller which is movably guided relative to the guide means is provided on the wooden ring runner. Is proposed, but a runner member must be provided for each of the plurality of wooden ring runners, which increases the number of parts and complicates the structure of the curtain rail.

The present invention also solves such a problem in the combination of the guide means and the runner member, and has a new structure in which the wooden ring runner can move smoothly with a relatively simple structure. and an object thereof is to <br/> provide rail.

[0012]

Means for Solving the Problems According to the first aspect of the present invention, there is provided a wooden pole which is mounted substantially horizontally near an upper portion of an opening portion of a living space, In a curtain rail in which a plurality of wooden ring runners are movably fitted to a pole, an upper portion and a window-side upper portion of the wooden pole are provided.
Further, a sliding body continuous in the longitudinal direction is provided so as to protrude from the surface of the wooden pole.

Accordingly, when the wooden ring runner moves, the inner peripheral surface of the wooden ring runner moves while being in contact with the surface of the sliding member provided on the wooden pole, and the wooden ring runner moves as compared with the case where there is no sliding member. Sliding resistance can be greatly reduced.

[0014]

Further , when opening and closing the curtain while pulling the curtain from a position slightly away from the window, the inner peripheral surface of the wooden ring runner moves while being in contact with the surface of the sliding body provided on the window-side upper portion of the wooden pole. In other words, the sliding resistance can be reduced as compared with the case without the sliding body.

According to the present invention for solving the above-mentioned problems, claim 2 is provided.
