Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for eliminating a difference in slack between roll blinds installed on inclined windows and skylights.

[Prior Art] Roll blinds installed on skylights or inclined windows
It is known from 60-26595 and 60-26596. The known roll blind is a support bar attached to one side of the window, left and right brackets attached to both ends of the support bar, a roll pipe supported by the bracket, and a roll pipe wound around the roll pipe. The screen, the spring that rotates the roll pipe in the direction to wind the screen, the weight bar attached to the free end of the screen, the left and right wire bases attached to the opposite ends of the window, and the left and right wires. A screen opening / closing cord that has one end fastened to one of the bases, penetrates the weight bar in the axial direction, reaches the other wire base, and is further pulled out from the wire base, and a hanging tool that hooks the screen opening / closing cord. The left and right wire stoppers provided near both sides of the It consists of a guide wire that penetrates the weight bar in the string direction and reaches the left and right wire bases and is fixed there.When the screen opening / closing cord is pulled against the spring, the weight bar is guided by the guide wire and the screen is When the screen is pulled out from the roll pipe, the screen is pulled out until the weight bar hits the wire base, then the roll blind is closed by hooking the screen opening / closing cord to the hook, and the screen opening / closing cord is removed from the hook and released, and the screen springs. Will automatically wind the roll pipe and open the blinds.

[Problems to be solved by the invention] It is not easy to attach the wire bases on the opposite side of the window to the roll pipes completely parallel to each other, or to wind the screen uniformly on the roll pipes. When the weight bar comes into contact with the left and right set bases, there is often a slack difference between the left and right sides of the screen. In a known roller blind, the mounting positions of the left and right set bars have to be changed in order to eliminate the difference between the left and right slacks, but since the mounting position is often a high place, it is not always necessary to change the mounting position. It wasn't easy.

The present invention has been made to solve this problem, and an object of the present invention is to provide a roll blind mechanism for a skylight and a tilted window that can easily eliminate the difference between the left and right slack of the screen. It is in.

[Means for Solving the Problems] In order to achieve the above object, the means adopted by the present invention is, as shown in FIG. 1, a wire base 38 with which a weight bar 35 abuts a main body 48 and a weight bar receiver 43. A shaft hole 49 is formed from the adjuster 44 and penetrates the body 48 in the weight bar moving direction, an adjuster groove 41 into which the adjuster 44 fits is provided in the middle of the shaft hole, and a weight bar 35 fits into the weight bar receiver 43. This is because the shaft portion 46, which cannot be rotated, is provided in the shaft 45 and the shaft hole 49, and the male screw 47 provided on the outer periphery of the shaft portion is engaged with the screw 42 to be provided on the inner periphery of the adjuster 44.

[Operation] When the screen opening / closing cord 33 is pulled out and the screen 20 is pulled out, and when the weight bar 35 is brought into contact with the wire base 38 and there is a slack difference between the left and right of the screen 20, turn the adjuster 44 on the slack side. The body of the weight bar receiver 43
Reduced the protruding length from 48, where the screen opening and closing cord
When 33 is pulled hard, the slack side of the screen 20 is stretched and the slack disappears.

[Embodiment] An apparatus of the present invention will be described based on an embodiment shown in the drawings.

As shown in FIG. 1 and FIG. 2, the support bar 30 of the roller blind is attached to one side of the window 50, and the left and right brackets 11 are fixed to both ends of the support bar. The roll pipe 10 is rotatably supported by the left and right brackets 11, and the screen 20 is wound around the roll pipe. A weight bar 35 is attached to the free end of the screen 20. Plates 39 are fixed to the left and right ends on the opposite side of the window 50, and the wire base 38 is attached to the plates. Guide wire stoppers 36 are attached near both sides of the support bar 30, and the starting ends of the left and right guide wires 31 are fixed to the guide wire stoppers. The left and right guide wires 31 penetrate the weight bar 35 in the chord direction and reach the wire base 38. The end of the guide wire 31 is the wire base
It is wound around a reel shaft 54 attached to 38 and fixed. The screen opening / closing cord 33 has a wire base with one starting end
It is fastened to 38, penetrates the weight bar 35 in the axial direction, reaches the other wire base 38, then turns around the guide 37 and hangs.
It is hooked to 32. The left and right wire bases 38 are provided with weight bar receivers 43 projecting toward the weight bar 35, and the projecting length thereof is adjusted by an adjuster 44.

As shown in FIG. 3, the weight bar receiver 43 includes a head portion 45 having a concave surface that fits into the weight wire 35, and a shaft portion 46 extending from the head portion. The shaft portion 46 has a columnar shape in which both sides of the cylinder are removed, and a male screw 47 is formed on the cylindrical surface. The shaft portion 46 is inserted into a shaft hole 49 of a synthetic resin main body 48 having a cross-section of a torus shape. An adjuster groove 41 that overlaps the shaft hole 49 is formed in the main body 48. The adjuster groove 41 opens on the front side of the roller blind. An adjuster 44 is inserted into the adjuster groove 41, and a weight bar support is inserted in the adjuster.
A female screw 42 that engages with the male screw 47 of the shaft portion 46 of 43 is provided. The outer circumference of the adjuster 44 is knurled so that it can be lightly rotated with a finger. Since a part of the outer peripheral surface of the adjuster 44 is exposed from the adjuster groove 41, the protruding length of the weight bar receiver 43 from the head portion 45 can be adjusted by turning it with a finger.

As shown in FIG. 4, when the screen 20 is pulled out until the weight bar 35 reaches the weight bar receiver 43 of the wire base 38 by pulling the open / close operation code 33, slack is generated on either the left or right side of the screen 20. In this case, turn the slack adjuster 44 with your finger and use the body 48 of the weight bar receiver 43.
When the screen opening / closing cord 33 is pulled more strongly by decreasing the protruding length from the weight bar receiver 43, as shown in FIG. 5, the weight bar receiver 43 retracts, so that the slack side of the weight bar 35 is the main body.
Get closer to 48. As a result, the slack of the screen 40 is eliminated, and the screen 20 is uniformly strained from side to side.

[Advantage of the Invention] As described above, the roll blind provided with the mechanism of the present invention is different from the conventional one in which the mounting position of the wire base with which the weight bar abuts is changed to eliminate the left-right slack difference of the screen. Even if the roll blind is installed in a high place, it can be easily done by changing the wire base contact position on the left and right of the weight bar by simply turning the wire base adjuster with your finger to eliminate the screen slack difference. In addition, it has an excellent effect that the difference between the left and right slack of the screen can be eliminated.
