Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for attaching a roll blind to a wall, ceiling, etc.

[Prior art] Instead of attaching the bracket of the roll blind directly to the wall surface, the installation work is facilitated by installing the roll blind using a device consisting of a set bar to which the bracket is attached and an L-shaped support fixed to the wall surface, etc. Not only that, but you can also easily adjust the installation position. However, in the conventional device, as shown in Utility Model Application No. 57-204393, a hook member having hook-shaped portions formed on the upper and lower sides is fixed to a support, and a set bar is attached to the upper and lower hook-shaped portions of the hook member. However, there is a problem in that it is not easy to hang the upper hooked part of the set bar onto the upper hooked part of the hook member because the condition cannot be seen. In particular, the front edge of the set bar to which the front cover can be attached has a long horizontally protruding front edge, making it extremely difficult to install the roll blind using conventional equipment. Further, although the lower hooked portion is fixed with a screw or the like, the upper hooked portion cannot be fixed, which causes the problem of vibration when the screen is rolled up.

[Purpose of the invention] The present invention facilitates installation of a set bar, especially a set bar to which a front cover can be attached.
The present invention attempts to solve the above problem by providing a roll blind mounting device that can prevent chatter when the screen is rolled up.

[Structure of the invention] In order to achieve the above object, the device of the invention is characterized by bending both sides of the vertical plate part of the support into a U-shape, and bending the upper edges of the sides downwards from the front. A cam lever and a support cam are inserted into the gap between the side parts and the vertical plate part, and a U-shaped part is formed on the lower edge of the support cam that bends upward in the front, and when the cam lever is turned to one side, both sides The cam groove of the cam lever and the cam pin of the support cam are formed so that the distance between the U-shaped upper edge of the cam lever and the U-shaped lower edge of the support cam becomes wider and becomes narrower when turned in the other direction. Therefore, by operating the cam lever, the upper and lower edges of the set bar smoothly fit into the U-shaped upper edges on both sides and the U-shaped lower edge of the support cam. Even a protruding set bar can be easily attached to the support. By attaching cushioning material such as rubber to the inner and lower surfaces of the horizontal plate part of the support and pushing up the set bar with the support cam so that its upper edge touches the cushioning material, it is possible to prevent vibration when the screen is rolled up. It is.

[Example] The apparatus of the present invention will be described based on an example shown in the drawings. As shown in FIG. 1, the roll blind support 10 includes an L-shaped horizontal plate part 11 and a vertical plate part 12, and one or both of the horizontal and vertical plate parts are attached to a wall surface 13 or the like by screws 14. Fixed via etc. Both side portions 15 of the vertical plate portion 12 are bent into a U-shape and face each other, forming a gap 16 between the vertical plate portion 12 and the vertical plate portion 12 . The upper edges of the side portions 15 are bent downward at the front to form a U-shaped portion 17. void 16
A cam lever 20 and a support cam 30 are inserted into the cam lever 20, and the cam lever 20 is rotatably attached to the vertical plate by a rivet 21. The support cam 30 is vertically slidably inserted between the front surface and both side portions 15 of the cam lever 20, and its lower end portion is bent upward to form a U-shaped portion 37. The U-shaped portions 17 on both sides grip the upper edge 41 of the set bar 40, and the supporting cam U-shaped portion 37 grips the lower edge 42 to hold the set bar 40. A bracket 50 is screwed to the set bar 40, and a roll blind main body 51 is supported by a bearing on the bracket. A front end 43 of the set bar 40 projects forward along the ceiling and connects a front cover 44 in a rotatable and detachable manner. A screen 52 having a weight bar 53 attached to its tip is pulled out from between the front cover 44 and the set bar 40. A cushioning material 18 such as rubber is attached to the inner and lower surface of the horizontal plate portion 11, and a set bar 40 is attached to the cushioning material.
The upper edges 41 of the two abut against each other.

As shown in FIG. 2, caps 45 are attached to both ends of the set bar 40. Since only the front cover 44, the drawn-out screen 52, the weight bar 53 at its lower end, and the weight bar caps 54 at both ends are visible from the front, the appearance of the entire roll blind is clean and neat. The cushioning material 18 is attached to the inner and lower surfaces of the vertical plate portions 11 of the side portions 15 and is aligned with the U-shaped portion 17. A rivet 21 for fixing the cam lever 20 is located on the center line of the support 10. Knob 22 of cam lever 20
When the U-shaped portion 37 of the support cam 30 is turned from the position shown by the solid line to the position shown by the chain line, the U-shaped portion 37 of the support cam 30 is lowered from the position shown by the solid line to the position shown by the chain line. Both sides of the support cam 30 are along the inner surfaces of the both sides 15 of the support 10, and the U-shaped part 37 is located in the opening between the sides 15.

As shown in FIG. 3, the cam lever 20 inserted into the gap 16 of the support 10 is rotatably attached to the vertical plate portion by a rivet 21. As shown in FIG. A cam pin 33 provided on the center line of the support cam 30 fits into the cam groove 23 of the cam lever 20 . Since the small protrusion 24 is formed at the lower end of the cam groove 23, the position of the cam pin 33 at the lower end of the cam groove 23 is stable, and the position of the cam pin 33 will not shift unless operated from the outside.

Next, installation of a roll blind using the device of the present invention will be explained. Horizontal plate portion 1 of support 10
1 or vertical plate part 12 to the building side such as a window frame, wall surface, ceiling 13, etc. as shown in FIGS. 1 and 2 with screws 14.
Fix it with. Turn the knob 22 of the cam lever 20 to the position shown by the chain line in FIG. 2, lower the support cam 30 to the position shown by the chain line, and widen the distance between the U-shaped parts 17 on both sides and the support cam U-shaped part 37. In this state, set bar 4
0 on the support cam U-shaped portion 37.
Needless to say, this work is easy because it is done by observing the state. Even if the front end 43 of the set bar 40 to which the front cover is attached protrudes forward, the lower edge 42 can be easily inserted into the U-shaped part 37 even with the front cover 44 attached. Next, when the upper edge 41 of the set bar 40 is placed on the front surface of both sides 15 and the knob 22 is returned to the original position shown by the solid line, the support cam 30 lifts the set bar 40 and the upper edge 41 automatically moves to the both sides. At the same time, the upper edge 41 of the set bar 40 bites into the lower surface of the cushioning material 18. In this way, the roll blind main body 51
The set bar 40 holding the
Attached to 0. Unlike previous devices in which the hook of the set bar had to be hooked on the hook of the support invisibly, the installation of the roll blind is significantly easier, even though the front end 43 of the set bar 40 projects forward. Furthermore, even if the front cover 44 is attached to the front end, the set bar 40 can be easily attached to the support 10.
After installation, the position of the cam pin 33 of the support cam 30 is stabilized by the small protrusion 24 as shown in FIG. 3, so there is no risk that the set bar 40 will come off the support 10. Since the upper end 41 of the set bar 40 bites into the cushioning material 18, vibrations during winding up of the screen are absorbed by the cushioning material 18, thereby preventing chatter of the roll blind.

[Effects of the invention] As mentioned above, the device of the present invention is different from the conventional device in which the upper hook of the set bar had to be hung on the upper hook of the support in a visible state. The installation of the roll blind is significantly easier, as the set bar can be automatically attached to the support simply by inserting the edge into the U-shaped upper edge of the support cam and then turning the cam lever. It has the special effect that even a set bar can be easily installed. Furthermore, since the upper edge of the set bar comes into contact with the cushioning material, it also has the effect of preventing the roll blind from chattering.
