Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a support bracket that supports a screen winding shaft of a roll blind.
[0002]
[Prior art]
One type of roll blind is one in which both ends of the winding shaft are rotatably supported by independent support brackets, and the support brackets are attached to the mounting surface.
[0003]
In such a roll blind, since independent support brackets are attached to the mounting surface, fine adjustment is performed so that the winding shaft is supported in the horizontal direction after the support bracket is attached to the mounting surface. There is a need. This is because if the winding shaft is not supported in the horizontal direction, the screen is unwound.
[0004]
Thus, the roll blind provided with the fine adjustment apparatus which finely adjusts the support position of a winding shaft is disclosed by patent documents 1-3.

[Problems to be solved by the invention]
The fine adjustment devices disclosed in Patent Literature 1 and Patent Literature 2 are configured to finely adjust the height of the winding shaft by rotating an adjustment screw. Therefore, there is a problem that the adjustment screw is loosened due to vibration during the raising / lowering operation of the screen, and the height of the winding shaft is distorted.
[0007]
Patent Document 3 discloses a fine adjustment device in which the height of a winding shaft is adjusted with an adjustment bolt and then fixed with a fixing bolt. In this fine adjustment device, the height of the winding shaft after adjustment can be prevented by the action of the fixing bolt. However, similarly to Patent Document 1 and Patent Document 2, in order to enable the adjustment bolt to be operated from below, it is necessary to provide the adjustment bolt on the support bracket between the edge of the winding shaft and the support bracket. Therefore, there is a problem that the support bracket is enlarged in the axial direction of the winding shaft.
[0008]
An object of the present invention is to provide a roll blind capable of reliably performing fine adjustment of a support position of a winding shaft and preventing an increase in size of a support bracket.
[0009]

[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A support bracket 1 shown in FIG. 1 is fixed to a mounting surface such as an upper frame of a window and rotatably supports one end of a winding shaft 2 of a roll blind. The other end of the winding shaft 2 is rotatably supported by a similar support bracket.
[0014]
The support bracket 1 supports the mounting position of one end of the winding shaft 2 so that it can be finely adjusted in the vertical direction, and the other support bracket supports the mounting position of the other end of the winding shaft 2 so that it cannot be finely adjusted. .
[0015]
A bearing fixing plate 3 is fixed to one support bracket 1 so that the position thereof can be adjusted, and a base end portion of a support shaft 4 that rotatably supports one end of the winding shaft 2 is fixed to the bearing fixing plate 3.
[0016]
The detailed configuration will be described. A base end of the support shaft 4 is fixed to a bearing portion 5, and a flange portion 6 is formed on the bearing portion 5. The flange portion 6 is fixed to the bearing fixing plate 3 with screws 7.
[0017]
The bearing portion 5 penetrates the bearing fixing plate 3 and protrudes toward the support bracket 1, and the protrusion engages with a long hole 8 formed in the support bracket 1 in the vertical direction. Therefore, the bearing fixing plate 3 is supported by the support bracket 1 so as to be movable up and down along the long hole 8.
[0018]
In the bearing fixing plate 3, an arc-shaped first guide hole 9 is formed on one side of the mounting position of the support shaft 4, and a long hole-shaped second guide hole 9 is formed on the other side of the mounting position of the support shaft 4. A guide hole 10 is formed.
[0019]
Screw shafts 11 and 12 projecting from the support bracket 1 are passed through the first and second guide holes 9 and 10, and nuts 13 and 14 are screwed into the tip portions of the screw shafts 11 and 12, respectively. Has been. Accordingly, as shown in FIGS. 2 to 4, when the nuts 13 and 14 are loosened, the bearing fixing plate 3 can rotate along the first and second guide holes 9 and 10 with respect to the support bracket 1. It has become.
[0020]
If the nuts 13 and 14 are tightened, the bearing fixing plate 3 is fixed to the support bracket 1 so as not to rotate.
An arc-shaped third guide hole 15 is formed in the lower portion of the support bracket 1, and a guide shaft 16 protrudes from the bearing fixing plate 3 in the third guide hole 15. Therefore, when the bearing fixing plate 3 rotates with respect to the support bracket 1, the guide shaft 16 moves along the third guide hole 15.
[0021]
When the bearing fixing plate 3 rotates with respect to the support bracket 1, as shown in FIGS. 2 to 4, the support shaft 4 is located away from the center of rotation of the bearing fixing plate 3. It moves up and down along.
[0022]
A large number of irregularities 17 are formed at equal intervals on the lower edge of the third guide hole 15, and the guide shaft 16 moves while engaging with the irregularities 17. Therefore, when the bearing fixing plate 3 is rotated with respect to the support bracket 1, an appropriate click feeling can be obtained.
[0023]
Now, in the roll blind configured as described above, one end of the winding shaft 2 is placed on the support shaft 4 while the other end of the winding shaft 2 is positioned by the other support bracket at the time of attaching to the window frame or the like. It is supported so that it can rotate.
[0024]
In this state, when the nuts 13 and 14 are loosened and the bearing fixing plate 3 is rotated along the first to third guide holes 9, 10, and 15, as shown in FIGS. The height changes.
[0025]
When the nuts 13 and 14 are tightened at a position where the height of the support shaft 4, that is, the height of one end of the winding shaft 2 becomes a desired height, the bearing fixing plate 3 is fixed to the support bracket 1, and the winding shaft One end of 2 is positioned.
[0026]
In the roll blind configured as described above, the following operational effects can be obtained.
(1) By rotating the bearing fixing plate 3 with respect to the support bracket 1, the height of one end of the winding shaft 2 can be finely adjusted. Therefore, the height of one end of the winding shaft 2 can be easily finely adjusted so that the winding shaft 2 is supported in the horizontal direction between the support brackets.
(2) Since the bearing fixing plate 3 is fastened to the support bracket 1 by the nuts 13 and 14, the fixing state of the bearing fixing plate 3 is not easily loosened by vibration during the screen lifting operation.
(3) Since there is no need to provide an adjustment screw as shown in the conventional example in the support bracket 1, the space between the winding shaft 2 and the support bracket 1 can be reduced. Therefore, the support bracket 1 can be downsized in the axial direction of the winding shaft 2.
(4) By the unevenness 17 provided in the third guide hole 15, it is possible to give a click feeling to the rotation operation of the bearing fixing plate 3. Therefore, the fine adjustment position of the height of the winding shaft 2 can be easily reproduced by counting the number of clicks.
[0027]
The above embodiment can be modified as follows.
The third guide hole 15 may be provided with irregularities on both upper and lower edges.
[0028]
【The invention's effect】
As described above in detail, the present invention can provide a roll blind capable of reliably performing fine adjustment of the support position of the take-up shaft and preventing an increase in the size of the support bracket.
