Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bracket for fixing a head box of a Venetian blind.

[Prior Art] The headbox of a Venetian blind is attached to a fixed part of a building, such as a ceiling or wall, via a bracket. The tilter box that supports the drum that tilts the slats of the blind is installed inside the headbox, and the tilter box is provided with a cover to protect the drum, so the bracket supports the headbox in the part where the tilter box is not located. I had to.
When the head box is sufficiently long compared to the tilter box, there is no problem, but when installing Venetian blinds in a narrow area such as a bay window, the length of the headbox is not long enough compared to the tilter box. There was a problem that Venetian blinds were difficult to install because the area that the brackets could support was limited.

[Problems to be solved by the invention] The invention attempts to solve the above problems by providing a bracket that can easily support the headbox even if the length of the headbox is not sufficient compared to the tilter box. It is something to do.

[Means for Solving the Problems] A characteristic feature of the present invention in order to achieve the above object is that the bracket also serves as a cover for the tilter box.

The bracket is a plate-shaped body made of highly elastic synthetic resin, and the plate-shaped body is provided with four J-shaped hooks and mounting holes. The length of the plate-shaped body along the longitudinal direction of the head box is equal to or slightly longer than the length of the tilter box. The four J-shaped hooks are provided symmetrically, two on each side, with respect to the center line along the longitudinal direction of the headbox, and are formed so as to hang over the upper edge bend of the headbox. The outer spacing of the four J-shaped hooks in the longitudinal direction of the head box is equal to or slightly smaller than the inner longitudinal width of the tilter box. The plate-shaped body has a fixed wing that projects horizontally from the head box in a direction perpendicular to the longitudinal direction of the head box, and the mounting hole is bored in the fixed wing.

[Function] When a tilter box is attached to the headbox and a bracket is pushed into the headbox from above the tilter box, the outer spacing of the four J-shaped hooks in the longitudinal direction of the headbox is equal to the inner spacing of the tilter box. Or because it is slightly smaller, the four J-shaped hooks are inside the tilter box, elastically deform inward and pass through the upper edge bend of the head box, and then spread outward again and hang on the upper edge bend of the head box. . At this time, the fixed wings of the plate-like body come into contact with the upper surface of the headbox to prevent the plate-like body from sinking further into the headbox. As a result, the bracket is connected to the head box and the inside of the tilter box is covered by the bracket, so there is no risk of dust entering the tilter box and interfering with the operation of the tilter drum or the like. When a screw or the like is passed through the fixed wing of the bracket to fix it to a ceiling or the like, the head box is also fixed through the bracket.

[Example] The bracket of the present invention will be described based on an example shown in the drawings. As shown in FIG. 1, the bracket 10 is a cross-shaped plate made of highly elastic synthetic resin. Four J-shaped hooks 12 hang down from the plate-like body, and two fixed wings 14 project horizontally in opposite directions. The tilter box 20 is housed in a head box 30, and the bracket 10 has four J
A letter-shaped hook 12 fits inside the tilter box 20 and is hooked onto the upper edge bent portion 32 of the head box 30. The fixed wing 14 has mounting holes 1 for fixing the bracket 10 to the ceiling etc. via screws 18.
6 is drilled.

As shown in FIGS. 2 and 3, the tilter box 20 is installed so that the cord outlet 21 at the bottom fits into the cord hole 31 of the head box 30. The tilter box 20 bears the guide roll 23, a rotary shaft 35 passes through it, and a tilter drum 36 is attached to the rotary shaft. Bracket 10 is fitted into tilter box 20 and headbox 30 so that its longitudinal centerline lies in the same vertical plane as the longitudinal centerline of the tilter box. The four J-shaped hooks 12 of the bracket 10 are provided in pairs symmetrically about the longitudinal center line, and the outer dimension spacing in the longitudinal direction is equal to the inner dimension spacing of the walls 22 on both longitudinal sides of the tilter box 20. The four J-shaped hooks 12 fit inside the tilter box 20 because they are slightly smaller.
In addition, four J opposing in the direction perpendicular to the longitudinal direction
The shape and dimensions of the glyph hook 12 are the head box 30.
Since it is equivalent to the upper edge bent portion 32 of the head box 30, when it is fitted into the head box 30, it elastically engages with the upper edge bent portion 32. Fixed wing 14 of bracket 10
hits the top surface of the head box 30 and regulates the depth of the J-shaped hook 12. The length of the bracket 10 in the longitudinal direction is longer than the tilter box 20, and the eaves portions 14 on both sides of the bracket 10 are longer than the walls 2 of the tilter box 20.
Prominent beyond 2.

As shown in FIG. 4, the bracket 10 has a cross shape as a whole, but the upper surface is flat, so that it can be brought into close contact with a ceiling surface or the like.

[Effects of the invention] As mentioned above, the bracket of the invention has four J-shaped hooks that fit inside the tilter box.
When the J-shaped hooks are pushed into the headbox from above so that they fit inside the tilter box inside the headbox, the four J-shaped hooks can be easily hooked onto the bends on the upper edge of the headbox, and the brackets and tilter box The three members of the head box become one. Additionally, since the bracket completely covers the tilter box, it also serves to protect the interior of the tilter box. In this way, the bracket and tilter box are installed at the same location on the headbox, so unlike conventional headboxes where the bracket is installed in the part where the tilter box is not installed, even if the length of the headbox is short, It is easy to install and has the excellent effect of being able to fixedly support the tilter box and head box as one unit.
