Description

[Detailed description of the invention]

The present invention relates to an improvement in a corner joint for connecting a head box split such as a Roman shade or a venetian blind installed in a bay window or the like.

[0002]

2. Description of the Related Art Rows installed on convex windows such as bay windows.
The head box of the man-shade and venetian blind is divided according to the window surface, and the divided parts are connected by a corner joint.
No. 515. In this known corner joint, a connecting plate extending in the longitudinal direction from the ends of the divided bodies on both sides is overlapped and rotatably mounted on the shaft, so that one divided body is fixed to the other divided body. It could not be rotated in the torsional direction.

[0003]

The head box of a Roman shade or venetian blind installed in a flat window has upper and lower upper edges bent inward to form hooks. Hang the front upper edge on the front hook of the bracket fixed to the ceiling, etc., push up the rear part around the hook, and hang the rear upper edge on the rear hook of the bracket. It was attached to. For this reason, it has been common to use a head box of the same shape and attach it to a bracket of the same shape, even if it is installed on a convex window such as a bay window. However, when the head box connected by a known corner joint is turned in a torsion direction in order to hang the front upper edge of one of the divided bodies on the front hook of the bracket fixed to the ceiling, the head box is connected via the corner joint. Since the other divided body extending in the intersecting direction rotates and hits the ceiling, it cannot be mounted on a bracket previously fixed to the ceiling. Therefore, all the brackets are attached to the divided body first, and the bracket attached to the divided body is fixed to the ceiling, or the corner joint is removed and the divided body is attached to the bracket fixed to the ceiling, and then the core is fixed. The two joints were attached, but the former requires two or more hands to be installed because the connected divided body must be kept at all times while the bracket is screwed to the ceiling. A high degree of skill was required because the mounting position of the device had to be accurate.

The present invention has been made to solve this problem, and an object of the present invention is to attach one of the divided parts of a head box to a bracket fixed to a ceiling surface in advance, and connect the other divided part to the other. It is to provide a corner joint in which the body does not hinder its mounting.

[0005]

In order to achieve the above object, the present invention employs a means in which at least one side of a corner joint for connecting divided parts of a head box is rotatably supported on a bearing. That is, the bearing body is fixed to the end of the divided body.

[0006]

The point that each of the divided bodies constituting the head box is connected to each other via a hinge which can be rotated horizontally via a hinge is the same as the conventional one, but one side of the corner joint. Unlike the conventional one, which is rotatably bearing, the divided body can freely rotate in the torsional direction. Therefore, since one of the divided bodies is attached to the bracket fixed to the ceiling in advance, even if it is rotated in the torsion direction, the other divided body connected via the corner joint does not rotate at all but maintains a horizontal position. I do.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a joint according to the present invention. As shown in FIGS. 1 and 2, each of the divided bodies 20 and 20 ′ of the head box is connected by a corner joint 10. The corner joint 10 is a cylindrical first body.
11 and a bearing body 31 for bearing the shaft portion 12 on one side of the main body.
Is formed from a hollow square second body 21 connected to the opposite side via a pin 13. The first and second bodies 11, 21 are pins 13
Can be rotated horizontally with respect to each other. The pin 13 is provided in the pin hole 1 of the connecting portion 14, 24 of the first and second main bodies 11, 21 which overlap each other.
It passes through 5 and 25 and penetrates the guide roll 23 disposed therebetween. Two guide rolls 22 are also arranged inside the second main body 21. The second main body 21 is fixed to the divided body 20 'via a fixing plate 26 and a set screw 27. The bearing body 31 is fixed to the divided body 20 via a fixing plate 36 and a set screw 37. The tip of the set screw 37 fits into the circumferential long hole 18 formed in the shaft portion 12 of the first main body 11, The longitudinal movement of the shaft 12 is restricted.

[0008] Although not shown, in the case of the Roman shade, the elevating code moves up and down inside the first and second bodies.
In the case of a venetian blind, the flexible shaft and the lifting / lowering code also pass through the guide roll. Such a divided body 20 connected to the divided body 20 'via the corner joint 10 has a horizontal width of 100 mm.
Not only does it rotate freely by nearly a degree, but also partially rotates in the torsional direction about the shaft 12.

FIGS. 3 and 4 show a state in which the divided bodies 20 and 20 'are installed on a wall surface such as a bay window which is bent at a right angle. The bracket 40 supporting the divided body 20 is fixed to the ceiling surface in advance, but a bracket (not shown) supporting the divided body 20 'is fixed to the divided body instead of the ceiling surface. First, hook the front upper edge hook 22 of the divided body 20 on the front hook 42 of the bracket 40,
The rear upper edge hook is pushed up by rotating about the hook, and the rear upper edge hook 23 is hung on the rear hook 43 of the bracket 40 to support the divided body 20 on the bracket 40 fixed to the ceiling surface. After that, when the divided body 20 is leveled and a bracket (not shown) previously attached to the divided body 20 'is fixed to the ceiling surface, the mounting of the head box is completed.

The mounting of the bracket 40 on the ceiling surface is extremely easy because it has nothing to do with the head box, and the mounting of the divided body 20 on the bracket 40 is a simple two-touch operation. When the bracket attached to the divided body 20 'is attached to the ceiling surface, one side is also supported and positioned by the divided body 20 already fixed to the ceiling surface.
Although it is screwing from the inside of 20 ', it can be said that it is much easier than the conventional one.

In the embodiment, the bearing is provided on one side of the corner joint, but the bearing may be provided on both sides. in this case,
The outer ends of the first and second bodies are both hollow shafts, and the first and second bearings are fixed to the ends of the divided bodies on both sides, and each divided body is free to the corner joint. Partial rotation in the torsional direction becomes possible.

[0012]

As described above, in the corner joint of the present invention for connecting the divided bodies of the head box, at least one of the divided bodies is partially rotatable in the torsional direction with respect to the corner joint. Different from those in which the divided bodies cannot rotate relative to each other in the torsional direction, even if they are inclined to attach one of the divided bodies to a bracket fixed to the ceiling in advance, Since the extended end does not hit the ceiling high, at least one of the divided bodies can be easily attached to the bracket fixed to the ceiling in advance, and if one of the divided bodies is attached to the bracket fixed to the ceiling , The other part supported by the bracket is supported by one part, making it easy to fix the pre-installed brat to the ceiling It exhibits an excellent effect that it becomes.
