Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for mounting a cover provided on a hanging rod of a curtain rail.

[0002]

2. Description of the Related Art As shown in FIG. 4, a hanging bar 11 of a curtain rail is fixed to the center of the lower surface of a disk-shaped base 23 screwed to a ceiling 13, but when this base 23 is exposed to the outside, it is unshaped. Therefore, a cover that covers the entire base 23 and the base of the hanging rod 10
Attach 24 to the hanging bar 10 from below and cover the base 23. Conventionally,
The cover 24 was screwed to the outer periphery of the base 23 and mounted on the base 23.

[0003]

There has been a problem that the work of rotating and screwing the cover 24 into the base 23 of the curtain rail hanging bar fixed to the ceiling is troublesome. The present invention has been made to solve this problem, and an object of the present invention is to provide a mechanism capable of attaching a cover to a base fixed to a ceiling with one touch.

[0004]

In order to achieve the above object, a means adopted by the present invention is to form a base into a dish shape,
Spring holes are made at two positions diametrically symmetric with respect to the center of the base, a diametrically extending spring member is placed on the upper surface of the base, and diametrically extends from the spring member.
The two ends of the two arms are respectively passed through the spring holes, and then project from the outer periphery of the lower surface of the spring in the diametric direction, and a concave portion is formed in the inner peripheral surface of the cover so that the claws formed at both ends of the arms of the spring member are inserted. Positioning means for holding the center position on the top is provided, and by these means, when the cover is pushed up from below by aligning the vertical position of the claw of the base and the concave portion of the cover, the cover is attached to the base with one touch. .

The base is a disc-shaped disk, and the body of the spring member is an annular body symmetrical in front, rear, left and right, for example, an annular body such as a circle, an ellipse, a diamond, and a hexagon. The spring hole provided in the base is an elongated hole through which the arm of the spring member passing therethrough can move in the diametrical direction. As positioning means for holding the center position of the spring member on the base, a foot extending integrally from the center of the spring member in a direction perpendicular to the arm is provided integrally with the spring member, and a positioning hole is provided in the base so that the foot can move freely in the extension direction. Is provided.
The claw formed at the tip of the arm has a lower surface formed as an inclined surface to taper the vertical width of the claw.

When removing the cover from the base, rather than pulling the cover downward, the cover is slightly rotated to disengage the pawl from the recess in the circumferential direction, and then pulled downward, the cover is more smoothly removed from the base.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments shown in the drawings. As shown in FIGS. 1 and 2, the hanging rod 10 of the curtain rail hangs from the center of the lower surface of the base 11, and a curtain rail (not shown) is attached to the lower end thereof. The base 11 is a dish-shaped aluminum disk, and is fixed to the ceiling 13 of the building by a set screw 12. The entire base 11 and the base of the hanging bar 10 are covered by a cover 14 and are not visible from the outside. The upper edge of the bowl-shaped cover 14 is a hollow cylindrical body having an inner diameter slightly larger than the outer diameter of the base 11, and at least two diametrically opposed recesses 15 are provided on the inner peripheral surface thereof.

On the upper surface of the base 11, a spring member made of synthetic resin is provided.
16 are arranged concentrically. The vertical width of the spring member 16 is the base 11
Is smaller than the depth of the dish-shaped upper surface. The base 11 has spring holes 21 extending in the left-right direction at two positions symmetrical with respect to the center. Two arms 18 extend in the left-right direction from the main body 17 of the spring member 16 and then break and pass through the spring holes 21 respectively.
The lower surface of the base 11 is again extended in the left-right direction. A claw 19 is integrally formed at the tip of the arm 18, and the claw 19 protrudes from the outer peripheral surface of the base 11 and fits into the recess 15 of the cover 14. An inclined surface is formed at the tip of the nail 19, and the thickness is tapered.

As shown in FIGS. 2 and 3, the base 11 is provided with positioning holes 22 extending in the front-rear direction at two positions symmetrical with respect to the center. Two legs 20 extend from the body 17 of the circular annular body in a radial direction perpendicular to the arm 18 with respect to the center thereof, that is, in the front-rear direction, and the legs are broken into the positioning holes 22 of the base 11. Since both arms 18 and both feet 20 fit into spring holes 21 and positioning holes 22 extending in the front-rear and left-right directions with respect to the center of the base 11, the center position of the spring member 16 on the base 11 is always kept constant.

[0010]

The operation of the embodiment of the present invention will be described with reference to FIG. As shown in FIG. 3A, before the cover is fitted to the base 11, the arm 18 passing through the spring hole 21 of the spring member 16 freely extends, and the claw 19 projects from the outer periphery of the base 11. The foot 20 is located at the center of the positioning hole 22.

When the cover 14 is pushed upward so that the left and right recesses 15 of the cover 14 come under the right and left claws 19, as shown in FIG. The claws 19 fit into the recesses 15 of the cover 14, and the arms 18 and the feet 20 slightly return along the spring holes 21 and the positioning holes 22. At this time, you hear a click, and release the cover there. Thus, the cover 14 can be attached to the base 11 with one touch.

When the cover 14 is to be removed, as shown in FIG. 3C, the cover 14 is attached to the base 11 and turned as shown by an arrow. The body 17 is pushed inward along the spring hole 21 by the
Is elastically deformed into an elliptical shape, and the foot 20 moves outward along the positioning hole 22. Then, when the cover 14 is pulled down, the cover 14 comes off the base 11 smoothly.

[0013]

As described above, the mechanism of the present invention is different from the conventional method in which the cover is screwed into the base and mounted.
Since this is a method in which the claws of the spring member provided on the base are fitted into the recesses of the cover and attached, an excellent effect that the cover can be attached to and detached from the base by one-touch operation is achieved.
