Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a blind bracket in which a blind head box can be attached / detached with one touch.

[0002]

2. Description of the Related Art A blind bracket that allows the head box to be attached and detached with one touch is disclosed in Japanese Utility Model Publication No. 1-76995.
No. The bracket has a block body slidably arranged under the horizontal plate-shaped bracket body,
A spring that is interposed between the bracket body and the block body to press the block body toward the front side is provided, and a bent edge portion that hangs on the left and right outer sides of the bracket body and a plate shape that hangs on the rear side. Mounting seat plates are integrally formed with each other, and the lower edge of the bent edge portion is extended inward to form a seat for supporting the block body, and front ears of the head box are provided on the left and right of the front end of the bracket body. A hook-shaped hanging seat for hanging is integrally provided, and a seat for restricting the rear surface position of the head box is integrally formed by extending the left and right outer edges of the mounting seat plate forward, and the head box rear is provided at the rear end of the block body. The receiving plate for hanging the side ear portion is formed, and the lower front surface of the receiving plate is formed as an inclined surface. When the front ears of the head box 2 are hung on the left and right seats and the rear side of the head box is lifted, the rear ears of the head box are locked to the block support plate, and the head box can be attached to the blocket with one touch. It was

When the head box is attached to the bracket, the front and rear ears of the head box are gripped by the left and right seats of the bracket body and the left and right receiving plates of the block body.
In addition, the rear surface of the head box contacts the left and right seats of the bracket body and is positioned.

[0004]

Since the bracket holds the head box at four points and abuts the rear surface at two points to determine the position, the bracket is not tolerated against errors in the fixed position and bending or warping of the head box. There was almost no range, and if the fixing positions of the brackets were misaligned or the headbox was warped, the mounting of the headbox was hindered.

As a bracket to which the head box can be attached even if the position of the bracket is slightly deviated, there are two fixed seats provided at the front and rear of the center of the bracket body and two movable seats provided at the left and right of the front and rear. What holds the head box at four points on the backing plate is actually fair 6-1611.
No. 1 is disclosed. This bracket can swing the head box around a pair of front and rear seats provided in the center of the bracket body, but the head box cannot be displaced in the front-back direction. The allowable range for bending or warping of the head box is not so large, and if the displacement of the fixing position of the bracket or the warp of the head box exceeds a certain level, the head box could not be attached.

The present invention has been made to solve this problem, and an object of the present invention is to provide a bracket capable of absorbing the mounting error of the bracket itself and the dimensional error of the bracket.

[0007]

In order to achieve the above-mentioned object, the means adopted by the present invention is that the front and rear ears of the head box are formed between the seat at the center of the front end of the bracket body and the left and right receiving plates of the block body. It was held at three places, and its seat was formed into a leaf spring shape that could be deformed in the front-rear direction, and the rear surface of the head box was brought into contact with a cushion member attached to the mounting seat plate of the bracket body to regulate the position. Especially.

[0008]

The bracket holds the headbox at three places: the seat at the center of the front end of the bracket body and the receiving plates on the left and right of the rear end of the block body. Since the bracket seat is deformable in the front-rear direction and the block body is slidable in the direction orthogonal to the head box longitudinal direction, the gripped head box moves left and right around the bracket center center seat. It is possible to swing around, and thereby it is possible to absorb an error in the mounting position of the bracket and a dimensional error such as a warp of the head box. The cushioning material attached to the mounting seat of the bracket body elastically abuts the rear surface of the headbox and restricts the movement of the headbox to the left and right, but since the cushioning material expands and contracts in the front-rear direction, the bracket must be attached accordingly. Positional errors and headbox dimensional errors can be absorbed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A bracket of the present invention will be described based on an embodiment shown in the drawings. As shown in FIG. 1, the bracket comprises a horizontal plate-shaped bracket body 1 and a block body 10 slidably inserted under the bracket body. Two left and right springs 1 are provided between the bracket body 1 and the block body 10.
The block body 10 is pressed forward with 9 interposed. The bracket body 1 is provided with hanging plate-like curved edge portions 2 at the left and right outer ends thereof, and a hanging plate-like mounting seat plate 3 is integrally formed at the rear end thereof. The lower edges of the left and right bent edges 2 extend inward to form a seat 4 for supporting the block body 10 underneath.

At the center of the front end of the bracket body 1, there is integrally formed a hook-shaped seat 5 for hanging the front ear portion of the head box. The seat 5 has a leaf spring shape that is elastically deformable in the front-rear direction. The left and right outer edges of the mounting seat plate 3 are slightly projected forward and the reinforcing plate 6 is integrally provided. The mounting holes 7 are formed in the left and right reinforcing plates 6, and the left and right mounting protrusions 9 of the cushion member 8 are fitted into the mounting holes. The center of the cushion member 8 projects forward to form a convex contact surface.

A foot 12 is hung from the rear end of the block body 10, and a book-like receiving plate 13 is integrally provided on the left and right of the foot to hang the lower rear ear of the head box from the outside, and the lower part of the receiving plate 13 is provided. The front surface is a slope 14. A long hole 11 in the front-rear direction is formed in the center of the block body 10. When the block body 10 is arranged below the bracket body 1, the hook 5 of the bracket body 1 enters the long hole 11. Spring grooves 15 that open upward and backward are provided on the left and right side surfaces of the block body 10, and a spring receiver 16 that receives the front end of a spring 19 is formed on the front surface of the groove. A stop 18 for receiving the rear end of the spring 19 is provided by partially cutting down near the left and right upper surfaces of the bracket body.

As shown by a chain line in FIG. 2, the inside of the front ear portion 21 of the head box 20 is attached to the seat 5 of the bracket body 1.
When the rear ear 22 is lifted around the front ear, the rear ear 22 pushes the block body 10 backwards against the spring 19 via the slope 14 of the block body 10, and then the ear portion When 22 exceeds the slope 14, the spring 19 pushes the block body 10 back forward, and as shown by the solid line, the receiving plate 1
3 hangs on the rear ear 22 from below and grips the head box 20 with the hanging seat 5 and the receiving seat 13. At this time, the cushion material 8 attached to the lower portion of the reinforcing plate 6 contacts the rear surface 23 of the head box 22 to prevent lateral slippage.

Since the cushion member 8 can be expanded and contracted in the front-rear direction, as shown in FIG. 3, if the front-rear position of the head box 20 with respect to the bracket main body 1 is within the allowable range D, the cushion member 8 will not move. Back 230
The side slip can be surely regulated by making contact with. As described above, the cushion member 8 can absorb some errors in the mounting position of the bracket body 1 and some warpage of the head box without hindering the mounting of the head box 20.

As shown in FIG. 4, the block 10 is slidable in the front-rear direction, and the seat 5 is elastically deformable in the front-rear direction. Therefore, the head box is centered on the seat 5 of the bracket body 1. 20 and the bracket body 1 can be swung relatively by an angle of ± A °. by this,
Even if the relative displacement of the mounting angle between the bracket body 1 and the head box 20 and the warp of the head box are relatively large, they can be absorbed. Therefore, even if there is an error in the mounting angle position of the bracket body 1 or the head box 20 is bent or warped, the head box can be attached to and detached from the bracket without trouble.

In the bracket of the embodiment, the hanging seat hangs the front ear part of the head box from the inside, but the hanging seat may be formed in a hook shape to hang the front ear part of the head box from the outside.

[0016]

According to the bracket of the present invention, the front ears of the head box are gripped by the central seat at the front end of the bracket body, and the rear ears of the head box are gripped by the receiving plates on the left and right ends of the block body. Since it is a system, and both the seat and the seat can be displaced back and forth, there are four locations of the fixed seats on the left and right sides of the bracket body and the moving support plates on the left and right sides of the block body, or the fixed seats and the block body in the front and rear of the center of the bracket body. Unlike the method of gripping the head box at four locations on the left and right moving support plates, the bracket and head box can be swung around the seat, or can be displaced in the front-rear direction.
Even if the head box is bent or warped, or the bracket mounting position has an error, the head box can be mounted on the bracket without any trouble. Further, in the bracket of the present invention, the side slip of the head box can be regulated by the flexible cushion material provided on the mounting seat plate of the bracket body, so that it is regulated unless the conventional head box is brought into contact with the seat of the bracket body. Unlike the one that could not be done, even if the head box has some bending or warping, or there is some error in the bracket mounting position,
It has an excellent effect that the head box can be reliably regulated.
