Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a side holder with a cover for a chain wheel of a chain operated roll screen.

[0002]

[Prior art]

 A chain wheel cover fixed to the shaft end of the hoisting roll is attached to the side holder that supports the hoisting roll of the chain-operated roll screen. This cover must always be opened in the direction of pulling out the chain. However, since the angular position of the side holder varies depending on the mounting surface, it is preferable that the angular position of the cover with respect to the side holder be adjustable. Such a side holder is disclosed in Japanese Utility Model Laid-Open No. 5-6093 and Japanese Patent Application Laid-Open No. 10-140955.

The former operates a lock pin that determines the angular position of the cover, and the latter operates a lever that determines the angular position of the cover, thereby adjusting the angular position of the cover with respect to the side wheel. However, in the former case, adjustment by the user is not always easy because the screwdriver turns the lock pin dial. Also, when the roll screen was installed in a position where the driver could not be used, the roll screen had to be removed once. The latter was not always easy to adjust by the user due to its complicated structure.

[0004]

[Problems to be solved by the invention]

 The present invention has been made to solve these problems, and the problem is that the roll screen has a simple structure and allows the user to easily adjust the angular position of the side wheel chain wheel cover. An object of the present invention is to provide a side holder with a cover.

[0005]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention employs a bearing in a side holder in which a bearing body of a winding roll is fixed to a holder plate with a chain wheel interposed therebetween. A disk part and a shaft part projecting toward the holder plate side are formed on the body, and the substrate part of the cover is rotatably fitted to the shaft part, and a plurality of recesses are formed on the outer peripheral side of the disk part. A cover part is formed on one side in the diameter direction of the substrate on the outer periphery of the disk part, an arc part having a larger diameter than the substrate part is formed on the other side, and an operation knob is provided on the outer periphery of the circular part and on the inner part. An arc-shaped slit forming a projection fitted into the recess is formed so that the arc can be resiliently swingable toward the holder plate.

By this means, when the operation knob protruding from the side holder is pushed toward the holder plate, the convex portion comes out of the concave portion and the cover becomes rotatable. Can be adjusted. Then, when the operating knob is released, the arc portion returns by elastic repulsion, the convex portion fits into the concave portion of the bearing portion corresponding to the angular position, and the cover is fixed to the bearing body. In order to reinforce the elastic repulsive force of the arc portion, it is preferable to form a symmetrical arc-shaped wing in which the tips on both sides of the projection come into contact with the holder plate in the substrate portion.

[0007]

[Embodiment of the invention]

 The present invention will be described based on an embodiment shown in the drawings.

FIGS. 1 and 2 are a side view and a longitudinal sectional view of a side holder according to an embodiment, and FIG. 3 is a side view of a cover.

The side holder covers a holder plate 1 fixed to a wall surface or the like, a bearing body 2 for supporting a shaft end of a winding roll of a roll screen, and an upper part of a chain wheel attached to the shaft end of the winding roll. The bearing 2 is fixed to the holder plate 1 via a set screw 13 with the cover 3 interposed therebetween.

The bearing body 2 has a shaft part 4 on the end face on the holder plate side and a disk part 5 on the winding roll side of the shaft part. Engraved.

The cover 3 has a substrate portion 7 rotatably fitted to the shaft portion 4 of the bearing body 2, and a cover portion 8 for a chain wheel is wound up from one side in the diameter direction of the substrate portion 7. Protruding toward the An arc portion 9 having a larger diameter than that of the disk portion 5 is formed on the other side of the substrate portion 7, an operation knob 10 is provided at the center of the outer periphery of the arc portion 9, and an arc-shaped slit is provided at the substrate portion 7 on the inner peripheral side. 11 are formed respectively. The slit 11 forms a convex portion 12 that fits into the concave portion 6 of the disk portion 5 and two symmetrical arc-shaped wings 14 at the center of the inner periphery of the circular arc portion 9. To be able to swing.

The two wings 14 having tips on both sides of the convex portion 12 come into contact with the holder plate 1 and try to push back the arc portion 9 pushed toward the holder plate by elastic repulsion.

Next, adjustment of the angular position of the cover of the side holder according to the embodiment will be described.

As shown in FIGS. 4 and 5, when the operation knob 10 is pushed toward the holder plate side against the elastic repulsive force of the arc portion 9 and the wing 14, the arc portion 9 of the cover 3 is moved to the holder plate 1 side. , The convex portion 12 comes off the concave portion 6 of the bearing body 2. Then, when the cover 3 is rotated in order to adjust the angular position of the cover portion 8, the convex portion 12 enters under the disk portion 5.

When the cover 3 is rotated to a predetermined angular position and the operation knob 10 is released, the arc portion 9 returns by elastic repulsion, and as shown in FIG. 6, the convex portion 12 becomes the concave portion at that angular position. 6, the angle of the cover 8 is adjusted, and the cover 3 is fixed to the bearing body 2 at the adjusted angular position.

[0016]

[Effect of the invention]

 As described above, the side holder with cover of the present invention is composed of a holder plate, a cover, and a bearing, and the angle of the cover can be adjusted by simply pressing the knob on the projecting cover toward the holder plate and turning it. It requires a special lock pin or lever in the past, and can be provided at a lower cost compared to the case where the angular position adjustment of the cover was not always easy, and the user could easily cover it. This has an excellent effect that the angle position of the lens can be adjusted.
