Description

[Detailed explanation of the idea] The present invention relates to a curtain rail structure.

Conventional curtain rails made of low-foam synthetic resin had the disadvantage that the running surface had minute irregularities, which caused noise when the runners were running.

The present invention was developed in view of these conventional drawbacks, and its main purpose is to provide a curtain rail with a running surface formed of hard synthetic resin within the curtain rail body, which is formed of low-foaming hard synthetic resin. By fitting the rail body,
Our purpose is to provide a curtain rail structure that suppresses noise when running on runners.Other purposes are:
To provide curtain rail transportation in which a rail main body can be easily attached to a curtain rail main body.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a curtain rail main body, which is an extrusion molded product of a hard synthetic resin such as low-foam polystyrene resin, and is cut into an appropriate length from a long length.

At one end of the base plate 4, which is substantially horizontal in the width direction of the curtain rail main body, a wall height contacting piece 6 which can come into contact with the wall 5 is formed over the entire length.

The wall height contact piece 6 serves as a mounting portion that is attached to the wall 5 by screwing in a screw.

7 is a reinforcing washer.

Two rail receiving portions 9 having L-shaped pieces 8 facing each other are vertically disposed in the middle portion of the substrate 4 in the width direction over the entire length thereof.

A recess 2 is formed in the rail receiving portion 9 and is open at the bottom.

3 is a rail body, which is an extrusion molded product of hard synthetic resin such as vinyl chloride resin or metal.

The running surface of the rail body 3 relative to the runner 13 is flat.

The rail main body 3 has a substantially C-shaped cross section with an open bottom.

An upper fin 10, which is approximately at the same level as the top of the rail body 3 and has approximately the same thickness as the top, extends left and right.

A lower fin 11 extends left and right from the upper and lower intermediate portions of the rail body 3.

As shown in FIG. 1, the rail body 3 is elastically fitted into the recess 2.

In such a case, the top surface of the rail body 3 comes into elastic contact with the top surface of the recess 2 , the tips of the upper fin 10 and the lower fin 11 come into elastic contact with the inner surface of the recess 2 , and the lower surface of the lower fin 11 comes into contact with the top surface of the rail receiver 9 . L
The horizontal piece 12 of the L-shaped piece 8 is in elastic contact with the upper surface of the horizontal piece 12, and furthermore, the cross section of the tip of the horizontal piece 12 of the L-shaped piece 8 is in elastic contact with the outer surface of the rail body 3.

In this way, the rail main body 3 can be attached to the recess 2 of the curtain rail main body 1 without wobbling.

According to this structure, the runner 13 rolls on the flat running surface of the rail body 3 made of hard synthetic resin such as vinyl chloride resin without minute irregularities, so that noise can be suppressed.
This allows the curtain 14 to be opened and closed quietly.

Note that the rail body 3 is made of hard synthetic resin or metal, but if it is made of metal, rolling noise of the runners 13 can be suppressed by covering the running surface with hard synthetic resin.

Furthermore, if the runner 13 is coated with a soft synthetic resin, the rolling noise of the runner 13 can be further suppressed.

In addition, since the upper fin 10 and the lower fin 11 are spaced apart vertically, when the rail body 3 is inserted into the recess 2, the outer peripheral surface of the rail body 3, the upper fin 10, the lower fin 1
1 and the inner peripheral surface of the recess 3. Due to the existence of this gap, vibrations transmitted from the rail body 3 to the curtain rail body 1 are damped by the waist runner 1.
This has the advantage that the occurrence of rolling noise during traveling can be further suppressed.

On the other side of the substrate 4, a front piece 15 is provided in the vertical direction.

A groove 16 is formed in the upper and lower intermediate portions of the front piece 15 over the entire length.

17 is a decorative cover, which is an extrusion molded product of synthetic resin such as vinyl chloride resin.

The decorative cover 17 has a shape that allows it to be inserted and fitted onto the outer peripheral surface of the front piece 15 from its length direction.

The lower end of the decorative cover 17 is made wide and considerably thicker than the material thickness of the decorative cover 17 to give it weight.

Further, two protrusions 18 are formed on the inner surface of the upper part of the decorative cover 17, and these protrusions 18 can be brought into contact with the grooves 16 of the front piece 15.

As shown in FIG. 1, the decorative cover 17 is inserted and fitted into the front piece 15 from the longitudinal direction.
is attached to the front piece 15.

With this configuration, the decorative cover 17 can hide the upper end of the runner 13 mounted on the rail body 3 and the curtain 14 suspended from the runner 13, making it possible to construct a so-called box-shaped curtain. It can be done.

In the figure, 20 is a corner reinforcing material, which includes a board 4 and a wall mounting piece 6.
It is inserted into a part of the corner of the substrate 4 to prevent it from bending downward at the base of the substrate 4.

FIG. 3 shows another embodiment, in which the lower surface of the rail body 3 is approximately aligned with the lower surface of the rail receiving portion 9.

FIGS. 4 and 5 show still another embodiment, in which three protrusions 19 are formed over the entire length on the top surface of the rail body 3, and these protrusions 19 are elastically attached to the upper surface of the recess 2. It was brought into contact with

By appropriately providing the upper fin 10, the lower fin 11, and the protruding portion 19 on the rail main body 3 as in these embodiments, fitting into the recess 2 of the curtain rail main body 1 can be facilitated.

Furthermore, by forming the protruding portion 19 in this way, many gaps are formed between the recess 2 and the rail body 3. This has the advantage that the vibrations transmitted to the curtain rail main body 1 are better suppressed, and the noise generated during running is further reduced than in the embodiment shown in FIG.

In summary, the present invention forms the curtain rail main body using low-foaming hard synthetic resin, forms a recess in the curtain rail main body that is open at the bottom along the entire length, and uses hard synthetic resin with a flat running surface. The curtain rail body is formed into a roughly C-shaped cross section with an open bottom, and the rail body is fitted into a recess.In other words, the curtain rail body is formed from low-foaming hard synthetic resin. Since the curtain rail is made of steel, it has enough strength to hang curtains, and the rail body made of low foam hard synthetic resin is inserted into the recess of the curtain rail body, so it can be used as a runner for running. By moving the rail body, which is made of hard synthetic resin with a flat running surface, it is possible to suppress noise and vibration of the curtain rail body. This has the advantage that it is possible to prevent noise between the two, and to greatly suppress the noise as a whole.

Moreover, since the rail body is fitted into the recess, rattling of the rail body can be eliminated, and rattling noise can be avoided even though the rail body is inserted into the recess.

In addition, horizontal pieces are provided in a direction that narrows the opening width from both opening edges in the width direction of the recess formed in the curtain rail body, and lower fins protruding from the lower part of the circular outer side surface in the width direction of the rail body are attached as described above. Since the rail body is fitted into the recess so as to overlap the top surface of the horizontal piece, the lower fin is locked to the horizontal piece, thereby fixing the rail body to the curtain rail body. Simply fit the rail body into the recess of the curtain rail body without using any fixing tools.
This has the advantage that the rail main body is fixed and the rail main body can be easily attached to the curtain rail main body.

Further, a lower fin is provided protruding from the lower part of the outer circular side surface in the width direction of the rail body, and an upper fin is provided protruding from the upper part of the circular outer side surface in the width direction of the rail body, vertically spaced apart from the lower fin. A gap is formed in the recess between the upper and lower fins, and the presence of this gap dampens vibrations from the rail body to the curtain rail body.
This has the advantage of further suppressing noise while driving.
