Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a bracket for supporting a skirted headbox of a Venetian blind.

[Prior Art] A Venetian blind bracket with an integral structure without moving parts, which can be easily fixed and supported by simply pushing in a head box, is disclosed in Japanese Patent Application Laid-open No. 750088/1988. something is known. However, while that bracket is suitable for headboxes with a flat bottom, when supporting a headbox with a skirt that closes off the air gap between the headbox and the top slat, the bottom wall of the bracket protrudes. It's bad for you to look at me.

In addition, since the bracket does not have a structure to support upward external force, if the slat hits the skirt while the Venetian blind is being raised or lowered, and an upward force is applied, there is a risk that the head box will be lifted up and come off. .

[Problems to be solved by the invention] The invention was made to solve the above problems, and its purpose is to make it possible to easily fix and support a skirted head box by simply pushing it in. To provide a bracket which is almost invisible from the outside after the headbox is attached and can stably support the headbox even against the force of lifting the headbox.

[Means for solving the problem] To achieve the above object, the bracket of the present invention supports a skirted head box,
In the cross section of the headbox, the front wall projects high to form a hook, the rear wall projects below the bottom surface to form a skirt, and the upper part of the rear wall forms a thick wall. The bracket that supports the head box is a synthetic resin molded body, and includes an inverted L-shaped main body, an upper hook formed at the top end of the main body, and a rim part formed along the center of the inner surface of the main body. and a protrusion formed on the upper surface of the inner corner of the rim part, the upper hook part engages with the hook of the head box, the protrusion engages with the thick part of the head box, and the lower hook part engages with the lower end of the skirt of the head box. It is formed.

[Operation] When the hook at the top of the front wall of the headbox is hung on the top hook of the bracket and rotated around the hook to press the rear wall of the headbox against the rim of the bracket, the bottom end of the skirt elastically presses the bottom hook. The head box rests on the lower hook part, and the thick part fits between the protrusions of the rim part, so that the head box is fixedly supported by the bracket.

The downward load of the fixedly supported head box is supported by the upper and lower hooks of the bracket, the upward external force is received by the upper surface of the inner corner of the rim, and the external force pushing the head box forward is supported by the protrusion of the bracket. Since the external force pushing it backward is supported by the front side of the rim, the headbox remains stable no matter what external force acts on it. For example, even if the slats hit the skirt when the blind is raised, the headbox will not lurch or come off as in the conventional case.

[Example] The bracket of the present invention will be described based on an example shown in the drawings. As shown in FIG. 1, in cross section, the front wall 11 of the head box 10 bulges forward in a slightly rounded shape, and its upper part protrudes high, bends backward, and then bends downward to form a hook 12. The rear wall 14 protrudes further downward than the bottom wall 13 to form a skirt 15, and the upper part protrudes a little to form a thick part 16.

The bracket 20 is a molded body of synthetic resin,
An inverted L-shaped main body 21, an upper hook 22 formed at the upper front end of the main body, a lower hook 25 formed to slightly protrude forward from the lower end of the main body, and the main body 21. It consists of an inverted L-shaped rim portion 23 along the inner surface of the rim portion, and a protrusion 26 protruding from the upper surface of the inner corner portion 24 of the rim portion.

When the headbox 10 is attached to the bracket 20, the hook 12 of the headbox is engaged with the upper hook part 22 of the bracket, the skirt 15 is engaged with the lower hook part 25, the thick part 16 is engaged with the inner corner part 24 and the protrusion 26, and the headbox is attached. 10 is firmly supported by the bracket.

As shown in FIG. 2, holes 29 for set screws are formed on the top and side surfaces of the main body 21 of the bracket 20. The width of the upper hook portion 22 is the same as that of the main body portion 21, and the width of the lower hook portion 25 is narrow and the same width as the rim portion 23 at the center of the main body portion, but these widths may vary depending on appearance, strength, etc. It is set appropriately. Main body part 2
It is desirable to fold the front end of bracket 1 downward and the lower end forward, respectively, to increase the strength of the entire bracket.

As shown in FIG. 3, attachment of the head box 10 to the bracket 20 is extremely simple. First, attach the inverted U-shaped hook 12 of the head box 10.
is hung on the U-shaped upper hook portion 22 of the bracket 20. Then, as shown by the arrow, rotate the head box around the hook 12 and place it on the bracket 2.
0 so that the rear wall 14 touches the front side of the rim part 23. The lower end of the skirt 15 of the head box 10 elastically rides over the lower hook portion 25 of the bracket 20, and the thick portion 16 is attached to the inner corner portion 24 of the rim portion 23.
and the protrusion 26, and is supported as shown in FIG.

The supported head box 10 has good stability,
The downward load is applied to the upper hook part 22 and lower hook part 25.
The upward external force is received by the upper surface of the inner corner 24 of the rim portion 23. External force from the front is applied to the front side of the rim part 23, and external force from the rear is applied to the protrusion 2.
6 each can be accepted. Therefore, no matter what external force is applied during use, for example, even if a force pushing up the skirt 15 is applied, there is no risk that the headbox 10 will jolt or come off the bracket.

Further, when the head box 10 is attached to the bracket 20, the bracket 20 is almost invisible from the outside, so that the overall appearance is good.

[Effects of the invention] As mentioned above, the bracket of this invention is one piece and has no movable parts, but it can be easily fixed by simply hooking the head box with a skirt and turning it. Since the thick part is fitted between the inner corner of the rim part and the protrusion, the head box can be stably supported not only by downward loads but also by upward external forces and external forces in the front and rear directions. It has no special effect.
