DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0015]
FIG. 1 is a perspective view showing a blind to which a balance is attached by a balance bracket according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view with the balance of FIG. 1 removed. In the figure, reference numeral 10 denotes a blind, and a large number of slats 16 are supported by a ladder cord 14 from a head box 12 of the blind 10. The head box 12 is attached to a mounting surface 20 such as a ceiling surface by a blind mounting bracket 18. A plate-like balance 22 is attached to the front surface of the head box 12 by a balance bracket 24 and covers the front surface of the head box 12. One or more balance brackets 24, preferably a plurality of the balance brackets 24 may be used at intervals in the longitudinal direction of the head box 12.
[0016]
As shown in FIGS. 2 and 3, the balance bracket 24 is fixed to the rear surface of the balance 22 and the bracket body 26 having a pressing surface 26 a that can be independently engaged with the head box 12 and can press the head box 12 from above. And a bracket guide 28 having a pressing surface 28a capable of pressing the head box 12 from below.
[0017]
The bracket body 26 is preferably made of metal and is formed by bending a plate material into a U shape, and the horizontal width of the plate material is substantially the same as or preferably smaller than the height of the blind mounting bracket 18. . Therefore, when the mounting surface 20 is a ceiling surface and the head box 12 is mounted on the ceiling surface by the blind mounting bracket 18, a gap formed between the upper surface of the head box 12 and the ceiling surface is defined as a bracket body. 26 can be inserted and moved in a horizontal posture. The U-shaped shape of the bracket body 26 is a shape that fits the dimensions of the upper surface of the head box 12, the front surface, and the rear surface. That is, the central portion of the U-shaped shape of the bracket body 26 is a pressing surface 26a that can be pressed from the upper side of the head box 12 to the upper surface and press the upper surface. The arm portions 26b1 and 26b2 overlap a part of the front and rear surfaces of the head box 12 from above. Thus, the bracket body 26 engages with the head box 12 with the upper surface of the head box 12, the front surface, and a part of the rear surface interposed therebetween. Further, a horizontal surface 26c that protrudes forward is formed from the lower end of one arm portion 26b1 of the bracket body 26 that overlaps the front surface of the head box 12, and a screw hole 26d is formed in the horizontal surface 26c. ing. Further, an upwardly extending wall is provided from the peripheral end of the horizontal surface 26c, and a portion surrounded by these walls is an opening 26e (locked portion) that opens upward.
[0018]
One bracket guide 28 is preferably made of metal and is formed by bending a plate material into an L-shape. A vertical surface 28 b located on the upper side of the L-shaped shape of the bracket guide 28 is fixed to the rear surface of the balance 22 by screws 29 and 29. Further, a horizontal pressing surface 28 a located on the lower side of the L-shaped shape of the bracket guide 28 extends rearward and can press the lower surface of the head box 12 from below the head box 12. The pressing surface 28a is preferably sized so as to be able to come into contact with the lower surface of the head box 12 in as wide an area as possible. An insertion hole 28c for inserting a screw is formed in the vicinity of the vertical surface 28b of the pressing surface 28a. In addition, a horizontal plane 28d that protrudes rearward in the horizontal direction is formed from the tip of the vertical surface 28b, and a locking portion 28e that is bent downward is formed at the tip of the horizontal plane 28d.
[0019]
The operation of attaching the balance 22 to the head box 12 using the balance bracket 24 configured as described above will be described with reference to FIGS. In this case, it is assumed that the head box 12 is already attached to the attachment surface 20 by the blind attachment bracket 18. The bracket guide 28 is fixed to the balance 22 with screws 29 and 29 in advance.
[0020]
Next, an operation of engaging an appropriate number of the bracket bodies 26 at an appropriate position of the head box 12 is performed. At this time, if the mounting surface 20 is a ceiling surface, the bracket body 26 is placed in a horizontal orientation as described above and inserted into the gap formed between the head box 12 and the ceiling surface. The bracket body 26 is completely inserted into the gap between the head box 12 and the ceiling surface so that one arm portion 26b1 of the bracket body 26 is located on the front surface and the other arm portion 26b2 is located on the rear surface. After that, the bracket body 26 is rotated to return to the normal posture from the lateral direction (see FIGS. 4 and 5A). Accordingly, the pair of arm portions 26b1 and 26b2 of the bracket body 26 overlap with a part of the front surface and the rear surface from above the head box 12, and the pressing surface 26a of the bracket body 26 overlaps with the top surface of the head box 12 from above. 26 engages the head box 12. In this way, the bracket body 26 is temporarily fixed to the head box 12 without easily falling off without using a coupling means such as a screw. If there is sufficient space above the head box 12, the bracket body 26 may be engaged from above the head box 12 in a normal posture without the bracket body 26 being turned sideways.
[0021]
Next, as shown in FIG. 5B, the locking portion 28 e of the horizontal surface 28 d of the bracket guide 28 is locked to the corresponding opening 26 e of the bracket body 26. As a result, the balance 22 is temporarily held by the head box 12 without falling off. Here, the balance 22 exerts a weight in the clockwise direction in FIG. 5 due to its weight, so that the balance 22 tries to fall down. However, since the locking portion 28e of the bracket guide 28 is locked to the opening 26e, A fall in this direction is prevented, and it is surely temporarily held.
[0022]
Next, the positions of the insertion hole 28c of the bracket guide 28 and the screw hole 26d of the bracket main body 26 are aligned, and the screw 30 is inserted into the insertion hole 28c from below and screwed into the screw hole 26d of the bracket main body 26. (FIG. 5C). As a result, the bracket body 26 and the bracket guide 28 approach each other, the pressing surface 26a of the bracket body 26 presses the upper surface of the head box 12, and the pressing surface 28a of the bracket guide 28 presses the lower surface of the head box 12. Then, the head box 12 is sandwiched. Thereby, the balance bracket 24 is fixed to the head box 12, and as a result, the balance 22 is attached to the head box 12 (FIG. 5D).
[0023]
The structure of the balance bracket is not limited to that shown in FIG. 3, but may be the balance bracket 24 ′ shown in FIG. In FIG. 6, the bracket body 26 ′ of the balance bracket 24 ′ omits the opening 26 e, shortens the length of the arm portion 26 b 2 ′, and shortens the length overlapping the rear surface of the head box 12. One bracket guide 28 ′ has a second vertical surface 28 f that rises vertically from the front end of the pressing surface 28 a ′ with the front end of the pressing surface 28 a ′ extending to the rear surface of the head box 12. 28 f overlaps the rear surface of the head box 12. An insertion hole 28g through which the screw 31 is inserted is formed in the horizontal plane 28d that protrudes rearward in the horizontal direction from the tip of the vertical surface 28b.
[0024]
When the balance 22 is attached to the head box 12 using the balance bracket 24 ′ shown in FIG. 6, the bracket body 26 ′ is engaged from above the head box 12 at an appropriate position of the head box 12. As in the manner shown in FIG. 5, when the gap between the head box 12 and the ceiling surface is small, the bracket main body 26 'is turned sideways so that the engagement between the head box 12 and the ceiling surface is performed. After being inserted into the gap, the bracket body 26 'is rotated so that one arm portion 26b1 of the bracket body 26' is positioned on the front surface and the other arm portion 26b2 'is positioned on the rear surface. Or when there is sufficient space above the head box 12, the bracket body 26 'may be engaged from above the head box 12 in a normal posture (FIG. 7A). )).
[0025]
Next, the pressing surface 28a ′ of the bracket guide 28 ′ fixed to the balance 22 is viewed from the front in parallel to the lower surface of the head box 12 from the gap between the head box 12 and the uppermost slat (not shown). It is inserted (FIG. 7B).
[0026]
Next, the positions of the insertion hole 28c of the bracket guide 28 'and the screw hole 26d of the bracket body 26' are aligned, and the screw 31 is inserted into the insertion hole 28c from below and screwed into the screw hole 26d of the bracket body 26 '. Wear it (Fig. 7 (c)). As the screwing progresses, the screw 31 also passes through the insertion hole 28g, whereby the bracket body 26 'and the bracket guide 28' approach each other, and the head box 12 is sandwiched between them. Thereby, the balance bracket 24 ′ is fixed to the head box 12, and as a result, the balance 22 is attached to the head box 12 (FIG. 7D).
[0027]
As described above, since the balance brackets 24 and 24 ′ are attached by sandwiching the head box 12, there is no need to drill the head box 12, and the head box 12 is attached to the attachment surface 20. In this state, the head box 12 can be easily attached later without removing the head box 12 from the attachment surface 20, and the attachment positions of the balance brackets 24 and 24 'to the head box 12 can be freely set. .
[0028]
In addition, after the balance 22 is attached to the head box 12 by the balance brackets 24 and 24 ', the bracket guides 28 and 28' can be applied even if a clockwise moment acts on the weight of the balance 22 in FIG. Since the pressing surfaces 28a and 28a 'press the lower surface of the head box 12 and receive such a moment, the balance 22 can be reliably prevented from falling.
[0029]
【The invention's effect】
As described above, by using the balance bracket of the present invention, it is not necessary to drill holes in the head box, and the balance can be easily attached to the head box later, and the attachment position can be freely set. Can also be secured.
