Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to improvement of a curtain rail for a curtain with a top decoration.

[Prior Art] As shown in Fig. 4, a curtain with a top decoration is one in which the top and bottom of two opening and closing curtains 35, 35 that are opened and closed from the center are covered with a top decoration curtain 36. As shown in Fig. 5, two curtain-shaped curtain rails are fixed to the inside and outside of the building wall, and two curtains are installed on the inner curtain rail 40 and the outer curtain curtain 41 on the outside. I had installed a top curtain.

[Problems to be solved by the invention] Fixing two curtain rails to the wall surface requires a lot of man-hours, and the fixing parts are close to each other, which makes it difficult to fix the curtain rail.

The present invention has been made to solve this problem, and an object of the present invention is to provide a curtain rail capable of installing a curtain with a decoration by fixing only one curtain rail to a building. Especially.

[Means for Solving the Problems] In order to achieve the above object, the means adopted by the present invention is, as shown in FIG. 1, a concave portion 17 on both inner surfaces of an upper curtain rail 10 fixed to a building. This is because the opening / closing curtain rail 20 that is provided so as to be able to expand and contract is provided with a convex portion 27 that fits into the concave portion on the outer end surface thereof. The open / close curtain rail is composed of an inner cylinder 25 and an outer cylinder 26 which are slidable with each other, and as shown in FIG. 2, the inner cylinder and the outer cylinder also have slits which overlap each other in the longitudinal direction. Along the slit 23 stopper nut 24
A bolt 28 is fitted so that the fixed position can be adjusted, and a coil spring 30 is slidably inserted between the stopper nut 24 and the inner cylinder 25.

[Operation] First, the top curtain rail 10 is fixed to the building. Then, the inner cylinder 25 of the opening / closing curtain rail 20 is pulled out so that the entire length is slightly longer than the inner width of the top curtain curtain rail 10, and the stopper nut 24 is fixed with a bolt 28. Next, the inner cylinder 25 is pushed against the coil spring 30 to hold the opening / closing curtain rail 20 so that the entire length thereof is slightly shorter than the inner width of the top curtain curtain rail 10. Next, the convex portion 27 at one end is fitted into the concave portion 17 on one side, and then the inner cylinder 25 is released while the convex portion 27 at the other end is fitted into the concave portion 17 on the opposite side. The inner cylinder 25 and the outer cylinder 26 are projected by the force of the coil spring 30, and the projections 27 on both sides are securely fitted in the recesses 17.
20 is supported and fixed to the top curtain rail 10. As described above, according to the present invention, since only one curtain rail is fixed to the building, and the other curtain rail is fixed to the curtain rail via the coil spring, the curtain rail can be easily attached.

[Embodiment] A curtain rail of the present invention will be described based on an embodiment shown in the drawings.

As shown in FIG. 1, both sides of the top curtain curtain rail 10 are symmetrical L-shaped arms 11 and 11, and both ends of the front portion are externally fitted to opposite ends of the arms 11 and 11. The expandable hollow rod 12 is assembled into a character shape as a whole. A set screw hole 13 is formed in each of the arms 11, 11 and a set screw 14 is passed through the set screw hole to fix the arm 11, 11 to the wall surface of the building. The expandable hollow rod 12 is a tubular body 15 fitted so as to be slidable with respect to each other,
It consists of 16. The ends of the arms 11, 11 on which the expandable hollow rod 12 is fitted are formed in two stages, and the cross section on the tip side matches the inner cross section of the inner cylinder 15 and the next cross section matches the cross section of the outer cylinder 16. Therefore, the expandable hollow rod 12 can be fitted onto the end of the arm 11 regardless of the orientation. Further, a protrusion 18 is provided at the end of each of the arms 11 and 11, and the protrusion is a hole 19 at the outer end of the cylindrical body 15 or 16.
I am addicted. One or more angular recesses 17 are provided on the inner side surfaces of the arms 11, 11.

Inner cylinder 25 with which the opening and closing curtain rail 20 is also slidably fitted
And outer cylinder 26, and caps on the outer ends of inner cylinder 25 and outer cylinder 26.
21 and 22 are fitted. On the outer end surfaces of the caps 21 and 22, angular protrusions 27 that fit into the recesses 17 of the arms 11 and 11 are provided.

As shown in FIGS. 2 and 3, a stopper nut 24 is slidably inserted inside the outer cylinder 26, and a coil spring 30 is inserted between the sputter nut and the inner cylinder 25. The inner cylinder 25 and the outer cylinder 26 have slits 23 extending in the longitudinal direction and overlapping each other, and a bolt fitted to the stopper nut 24 from the slits.
28 projects outward. A washer 29 is fitted under the head of the bolt 28. The end of the inner cylinder 25 in contact with the coil spring 30 is bent to increase the contact surface with the coil spring 30.

Next, the assembly and installation of the curtain rail of the present invention will be described.

Although not shown, the curtain runner is attached to the expandable hollow rod 12 and the opening / closing curtain rail 20 in advance. Arm 1
1 and 11 are fixed to a predetermined wall of the building with setscrews 14. Then, one end of the expandable hollow rod 12 is externally fitted so that the projection 18 and the hole 19 fit into the end of the one arm 11, and while the other end is pulled out, the projection 18 and the hole 19 are also formed at the end of the other arm 11. When fitted so as to fit, the top curtain curtain rail 10 is assembled in a state of being fixed to the wall surface.

The total length of the opening and closing curtain rails 20 is a decorative curtain rail 10.
Inner cylinder 25 or outer cylinder 26 so that it is 15 to 20 mm longer than
Withdraw. Then, the bolt 28 is displaced to sandwich the coil spring 30 between the stopper nut 24 and the inner cylinder 25, and the bolt 28 is tightened to fix the stopper nut 24. In this state, the inner cylinder 25 is inserted into the outer cylinder 26 against the coil spring 30 so that the total length of the opening / closing curtain rail 20 is shorter than the inner width of the arms 11 and 11. Fit in the recess 17 of the
Is aligned with the other recess 17 and the inner cylinder 25 is released. Coil spring 30
The other convex portion 27 is fitted into the other concave portion 17 by the force of, and the opening / closing curtain rail 20 is fixed to the top curtain curtain rail 10, and the curtain rail installation is completed. Although not shown, when the width of the curtain rail is long, the support bracket is fixed to the wall of the building to support the center of the upper curtain rail and the opening / closing curtain rail.

Opening and closing curtains 35, 35 and curtains on the curtain runner
When 36 is applied, the condition shown in Fig. 4 is reached and the curtain installation is complete. In this way, the assembly and fixing of the curtain rail is extremely easy. Although the upper decorative curtain rail whose installation width can be adjusted is shown as an example, it is desirable to integrally form both sides and the front surface of the upper decorative curtain rail when the installation width does not need to be adjusted.

[Advantage of the Invention] As described above, the curtain rail for a curtain with a decoration of the present invention can be assembled and installed by simply fixing one curtain rail to the building. Compared to the one that had to be fixed to the building, it is extremely easy to assemble and install, and has the excellent effect of speeding up construction.
