Description

[Detailed description of the invention] (Industrial application field) This invention relates to a mounting support device for a bracket member for a roll screen device, and is generally used for shielding windows that are openings in houses and partitioning rooms. The present invention relates to a mounting and supporting device for a bracket member for a roll screen device, which allows the roll screen device to be supported by the bracket member on a curtain rail material having a substantially C-shaped cross section for hanging curtains, which is commonly used in the industry.

(Prior Art) Conventionally, curtains have generally been hung to block windows, partition rooms, etc. A curtain rail material with a roughly C-shaped cross section is used to support the hanging of the curtain, and the curtain can be opened and closed by moving it horizontally via a runner that is slidably fitted to the curtain rail material. The curtain rail material itself is supported by the ceiling, wall, etc. so that it is suitable for the installation. On the other hand, recently, as houses become more Western-style, roll screen devices that open and close screen materials in the vertical direction by accumulating and releasing the elastic force of built-in coil springs are becoming more and more popular. It is supported by the ceiling, wall, etc.

(Problem that the invention aims to solve) However, although they are all used for controlling light and temperature, soundproofing, shielding, partitioning, and decoration, the supporting means differ as mentioned above due to differences in their structural features. Unavoidably, in order to change each other, it was necessary to replace the entire supporting means.

Therefore, this invention was devised in view of the above points, and allows the bracket member configured to support the roll screen device to be directly connected to the remaining curtain rail material, making it easy to attach and detach. To provide a mounting support device for a bracket member for a roll screen device, which can be easily and quickly replaced with a curtain, and is highly versatile in mounting to curtain rail materials of various shapes.

In order to achieve the above-mentioned purpose, this invention uses an elastic force that tends to spread when a curtain rail material having a substantially C-shaped cross section is inserted into an opening from below. A pair of resiliently engaging leg pieces that slide into sliding contact with each other and whose lower ends are locked on the inner surfaces of both sides of the opening after insertion are vertically inclined so that the distance between them gradually increases as they reach the lower end. A V-shaped mounting support is formed, and on the other hand, a mounting groove having an insertion portion in the inner bottom wall is aligned with the opening in the mounting base portion of the bracket member that comes into contact with the opening of the curtain rail material. The mounting base portion of the bracket member is mounted on the top of the mounting support with a mounting screw from the insertion portion via a flexible spacer material between the mounting groove and the opening. This is what I did.

(Function) By using the above-mentioned technical means, the mounting support with its top end is forcibly inserted into the opening of the existing curtain rail material against the elastic force generated in the elastic engagement leg itself. The mounting support is set by doing this, and then the mounting screw is inserted into the insertion part of the mounting base part of the bracket member and the spacer material that matches this insertion part, and in this state, the spacer material is opened. At the same time, by fitting the mounting screw into the top of the mounting support and pulling the mounting support, the entire structure is flattened.
The lower ends of the resiliently engaging leg pieces are engaged with the inner surfaces of both sides of the opening.

(Embodiment) An embodiment of this invention will be described below with reference to the drawings.

Reference numeral C shown in the figure is a curtain rail material C that is attached to the ceiling, wall, etc., and this curtain rail material C generally has a substantially C-shaped cross section as shown in the drawing. Various shapes are used, such as an approximately square C-shape, an H-shape, an inverted Y-shape, etc., but basically they are open at the bottom and have protruding parts on both sides of the opening. A liner having a substantially E-shaped cross section is slidably fitted thereinto.

Further, B is a bracket member that supports the roll screen device R, and this bracket member B is a bracket base B1 having a substantially L-shaped side surface as shown in the figure.
and a bowl-shaped bracket cup B2 can be removably combined. As the bracket cup B2, one having a square hole for connecting and supporting one end of the coil spring built in the roll screen device R, and the other having a round hole for supporting the shaft are selectively used. The mounting base part 1 of this bracket member B, that is, the bracket base B1, has a mounting groove 2 having approximately the same width as the opening of the curtain rail material C. As shown in the figure, the bottom wall of the mounting groove 2 is formed with one or more elongated or circular (not shown) insertion parts 3 that communicate with the outside at the end of the mounting base part 1. .

In order to abut and connect the bracket member B to the curtain rail material C, a mounting support 10, a spacer material 14, and a mounting screw 15 are interposed between both C and B.

As shown in FIG. 4, when the curtain rail material C is inserted into the opening from below, the mounting support 10 slides into contact with the edge of the curtain rail material C with an elastic force that is biased toward the opening, thereby preventing the insertion. After that, a pair of elastic engagement leg pieces 11 whose lower ends are locked to the inner surfaces of both sides of the opening are vertically inclined so that the distance between them gradually increases as they reach the lower ends,
The entire structure is formed to have an approximately inverted V-shaped cross section. The mounting support 10 itself is formed of a highly elastic spring steel plate, such as phosphor bronze, by cutting a suitably thick sheet material into a predetermined shape and bending it. The mounting support 10 shown in the figure is made by bending a rectangular sheet material into a rounded, approximately V-shape, and making a narrow cut 12 from the center on both sides of the opening edge to divide it into two parts, front and back. It is designed to be By doing this, as will be described later, when the two mounting screws 15 are screwed in separately, each of the divided elastic engagement leg pieces 11 is separately locked to the inner surface of both sides of the opening of the curtain rail material C. This further increases stability during installation and support.

The distance between the lower ends of the elastic engagement leg pieces 11 is not smaller than the width of the opening of the curtain rail material C, and the width of the upper end of the mounting support 10, that is, the width of the top even if rounded, is not smaller than the width of the opening of the curtain rail material C. It is assumed that it is not larger than that of the department. When the resilient engaging leg pieces 11 are pressed from the outside in order to bring them close to each other, a resilient force is exerted that tends to expand and restore the original shape.

Further, the spacer material 14 is inserted into the mounting groove 2 and the opening, which are recessed so as to correspond to the mounting base 1 of the bracket member B that is in contact with the opening of the curtain rail material C. It is made of rubber or flexible plastic and has a cylindrical or square tube shape so that the mounting screw 15 can be inserted therethrough. Its external size is approximately the same as the width of the opening or the mounting groove 2, its height is greater than the depth of the mounting groove 2, and it is attached to the mounting support 10 placed within the curtain rail material C as shown in the figure. When the resilient engagement leg piece 11 is expanded by screwing in the screw 15, it is assumed that the inner surface of the resilient engagement leg piece 11 is pushed into the curtain rail material C to the extent that it is crushed. The outer periphery of the upper end is chamfered in an arc shape so that they will come into contact with each other.

In addition, the mounting screws 15 are arranged so that the mounting base portion 1 is fixed so that the resilient engagement leg pieces 11 of the mounting support 10 inserted into the curtain rail material C are clamped to the inner surfaces of both sides of the opening. It is inserted through this 1 and the spacer material 14 and screwed onto the top of the mounting support 10. Therefore, a tap-shaped female screw hole 13 is drilled at the top so that the mounting screw 15 can be securely screwed, as shown in the figure.
By screwing in a total of two mounting screws 15 at the front and rear of the mounting support 10, rotational wobbling of the mounting support 10 itself can be prevented, and further stability of the bracket member B can be achieved during mounting support.

(Effect of the invention) This invention is constructed as described above, and when used, as shown in Fig. 4, it is possible to install a mounting support whose top part can be seen inside the opening of the existing curtain rail material C. The mounting support 10 is set by forcibly inserting the elastic engaging leg piece 11 against the elastic force generated in the elastic engagement leg piece 11 itself. Next, the mounting screw 15 is inserted through the insertion portion 3 of the mounting base portion 1 of the bracket member B and the spacer material 14 that matches this 3, and in this state, the spacer material 14 is fitted into the opening and the mounting screw is inserted. 15 is screwed into the female threaded hole 13, and the lower end of the resilient engagement leg piece 11 is locked to the inner surface of both sides of the opening so that the entire body is flattened by pulling the mounting support 10. When the pair of bracket members B are connected to the curtain rail material C in such a manner that they are opposed to each other, the roll screen device R can be mounted between the bracket members B.

Therefore, since the bracket member B can be attached to the curtain rail material C in a connected state,
The curtain and the roll screen device R can be easily replaced while leaving the curtain rail material C in place, and since there is no need to remove the curtain rail material C, it can be attached and detached freely, and the work can be done in a short time. It is also possible to adjust the distance between the bracket members B in accordance with the length of the roll screen device R, which in turn helps the smooth operation of the roll screen device R.

When the mounting support 10 is inserted into the opening of the curtain rail material C from below, it slides into contact with the edge of the curtain rail material C with an elastic force that tends to expand, and after insertion, the lower end touches the inner surface of both sides of the opening. A pair of elastic engagement leg pieces 1 that are engaged with the
1 are vertically inclined so that the distance between them gradually increases as they reach the lower end, and the cross section is formed into a substantially inverted V-shape. Since the mounting base part 1 is pulled tightly against the opening of the curtain rail material C, the mounting base part 1 is firmly attached to the opening of the curtain rail material C. Moreover, at this time, once the elastic engagement leg piece 11 is expanded within the curtain rail material C by its own elastic force that tends to expand, it becomes extremely difficult to remove it.
Coupled with the strong screwing force of the mounting screws 15, it can be firmly fixed, and the fixed position will not be shifted even by vibrations and shocks generated from the roll screen device R, which is repeatedly pulled out and wound up.

The flexible spacer material 14 interposed in the mounting groove 2 of the mounting base part 1 and the opening of the curtain rail material C is attached to the mounting base part 1 when the mounting screw 15 is screwed into the mounting support 10. When the mounting support 10 is pulled toward the side, a strong crushing force is applied to itself, which not only further encourages the elastic engagement leg pieces 11 to expand outward, but also causes the mounting support 10 to expand outwardly.
The screwing direction of the mounting screw 15 is regulated and corrected to ensure reliable screwing, and furthermore, the tilting of the bracket member B is prevented, thereby achieving further mounting stability.

In addition, once the mounting support 10 is inserted into the curtain rail material C, it is temporarily screwed with the mounting screw 15 through which the spacer material 14 is inserted, and in this state, the insertion portion 3 that communicates with the outside is used. This makes it easy to attach and detach the bracket member B. Not only that, since the bracket member B can be attached and detached from the curtain rail material C using only three members: the mounting support 10, the spacer material 14, and the mounting screw 15, there is no need to assemble complicated parts, making it easy to handle. is easy.

As explained above, according to this invention, the roll screen device can be easily installed via the bracket member that is fixed to the existing curtain rail material while leaving it in place, and it is also easy to handle as it can be attached and detached freely. As a result, it can be expected to have the secondary effect of promoting replacement and modification to roll screen devices, and has practical beneficial effects such as being highly versatile in installation, simple in structure, and inexpensive to provide. .
