DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll holding plate for holding a shaft end of a roll of a roll blind.

[0002]

2. Description of the Related Art At least one shaft end of a roll for winding a screen of a roll blind is supported by a roll holding plate. The conventional roll holding plate is fixed to the set bar extending parallel to the roll via a dedicated screw,
The set bar was fixed to a ceiling surface or a wall surface via a bracket.

[0003]

When the roll holding plate is screwed to the set bar, not only the screw is required but the number of parts is increased, but also the man-hour for screwing is required, and the cost increases accordingly. There was a problem that. The present invention has been made to solve this problem, and an object thereof is to fix a roll holding plate to a set bar without using a dedicated screw.

[0004]

In order to achieve the above-mentioned object, a means adopted by the present invention is to form a fit between the insertion portion of the holding plate to be inserted into the channel-shaped set bar and the set bar by a play-free intermediate. With the fitting, the claw part extending in the longitudinal direction of the set bar is formed integrally with the holding plate,
A protrusion protruding from the set bar is provided at the tip of the claw portion, and a fitting portion into which the protrusion fits is provided on the set bar.

[0005] It is desirable to provide a slight taper at the tip of the insertion portion to facilitate insertion of the holding plate into the set bar. It is not necessary that the number of the insertion portions and the projections of the insertion portions of the holding plate be limited to one, and two or more may be provided. Further, the insertion portion may be along either the upper surface or the lower surface of the set bar. Since the holding plate of the present invention does not require a dedicated screw for fixing to the set bar, the number of parts of the roll blind and the number of screwing steps are reduced, and the cost of the roll blind is reduced accordingly.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in the drawings. FIG. 1 is a sectional view showing a state in which a holding plate 1 of the present invention is fixed to a set bar 8, and FIG.
FIG. 2 is a view taken along line II-II. The holding plate 1 is a hard synthetic resin molded product, and has a bearing portion 3 provided with a shaft hole 2 for bearing a shaft end of a roll on one of upper and lower sides. On the other side of the upper and lower sides, there are an insertion portion 4 inserted into the inside of the set bar 8 and a claw portion 5 extending along the outer surface of the set bar 8. The set bar 8 is a channel made of sheet metal or extruded aluminum.

As shown in FIG. 1, a portion of the insertion portion 4 that vertically overlaps the claw portion 5 forms a long hole-shaped space 6. Insertion part 4
Of the set bar 8 is tapered to facilitate insertion into the set bar 8. The claw portion 5 extends in the center of the lower surface of the set bar 8 in the longitudinal direction of the set bar. The tip of the claw portion 5 is tapered so as to easily follow the lower surface of the set bar 8. 1 and 2
As shown in FIG. 7, a projection 7 projecting from the lower surface of the set bar 8 is provided at the tip of the claw portion 5 and the projection 7 is attached to the set bar 8.
Is fitted into the hole 9 formed in the center of the lower surface of the claw 5 by utilizing the elasticity of the claw portion 5. Once the projection 7 has been fitted into the hole 9, it does not come off even if a force acts to remove the holding plate 1 in the longitudinal direction of the set bar 8. However, when the protrusion 7 is removed from the hole 9 of the set bar 8 against the elastic repulsive force of the claw portion 5, the holding plate 1
Can be easily pulled out in the longitudinal direction of the set bar 8.

As shown in FIG. 3, the holding plate 1 is inserted into the set bar 8 in the direction of the arrow. Since the distal end of the insertion portion 4 is tapered, insertion into the set bar 8 is easy. Further, since the tip of the claw portion 5 is also tapered, it slides smoothly along the surface of the set bar 8. When the claw 5 slides along the surface of the set bar 8, the protrusion 7 at the tip pushes the surface of the set bar 8 by the elastic repulsive force of the claw 5, so that the protrusion 7 is located at the position of the hole 9 of the set bar 8. Upon reaching, it automatically enters the hole 9. Since the insertion of the insertion portion 4 and the set bar 8 is an intermediate fit without play, there is no possibility that the holding plate 1 in which the insertion portion 4 is fitted to the set bar 8 rattles and becomes unstable.

[0009]

As described above, in the holding plate of the present invention which supports the roll of the roll blind, the insertion portion is inserted and fitted into the inside of the set bar by an intermediate fit without looseness, and the projection of the claw portion is formed. This is a method to prevent the holding plate from slipping out by fitting the claw part into the fitting part of the set bar with the elasticity.No special screw is used, so the number of parts of the roll blind is reduced and the man-hour for screwing is not required. As a result, there is an excellent effect that the cost of the roll blind is reduced.
