Abstract

PROBLEM TO BE SOLVED: To provide a remote-controllable, self-advancing, and compact electrically- driven curtain opening/closing device capable of smoothly advancing itself, overlapping the terminal edges of curtains on each other which are moved from both ends of a curtain rail to the center part, and completely preventing a gap between the curtains. SOLUTION: This device comprises top runners 1, and runner rollers 3 and 7 provided with a pair of free rollers in the front and rear to be supported at both lower edges of a curtain rail 14 are pivoted to the top runner 1 via a supporting member. The top runner 1 is provided with both an electric motor 9 inside and a drive roller 13 interlocked with the drive shaft of the electric motor 9 via a decelerating mechanism and is moved by pressing the drive roller 13 into contact with the lower surface of the curtain rail 14. The device electrically moves the top runners 1 to open and close curtains. In this case, an engaging hole 2a to be engaged with a curtain suspending ring is formed for the tip of the front arm rod 2 of one top runner 1, and an engaging hole 2'a to be engaged with a curtain suspending ring is formed for the tip of the arm rod for intersection of the other top runner 1'. The tip locations of the arm rods 2 and 2' of both top runners 1 and 1' are displaced to each other so that the arm rods 2 and 2' may intersect and be overlapped on each other at the location where both top runners 1 and 1' collide with each other.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric curtain opening / closing apparatus having a self-propelled electric member for a curtain suspended on a window frame or the like, and more particularly to an electric curtain opening / closing apparatus for a stretchable curtain rail.

[0002]

2. Description of the Related Art In a conventional opening / closing device in which a leading runner, which is a self-propelled member incorporating an electric motor, slides from both ends of a curtain rail to open and close a curtain, the leading runners collide with each other and a rear end of the leading runner. Since the ends of the curtains were connected to each other, a gap was created between the curtains from both sides. In addition, since the gap between the curtains is generated, the inside of the room can be seen from the outside or the light of the outside light leaks, so that the person cannot sleep at night with peace of mind.

Further, since the leading runner is self-running, the curtain cannot be manually opened and closed. Therefore, an electromagnet for separating the driving roller pressed against the curtain rail is provided so that the curtain can be manually opened and closed. However, there is a method in which the driving roller is moved away from the curtain rail and moved manually. However, not only the structure of the leading runner becomes complicated, but also the cost increases.
In addition, installing an electromagnet or the like in such a leading runner causes the leading runner to be bulky, which imposes a heavy load on the curtain rail.

[0004]

In a curtain electric opening / closing device that arranges and moves the two leading runners toward or away from both ends and opens and closes a curtain suspended by a large number of curtain hanging rings connected to the leading runner, An engaging hole is provided at the tip of the arm rod for engaging the curtain suspension ring, and the other end is engaged with the curtain suspension ring at the tip of the crossover arm rod of the first runner. The provided, at a position where both the top runner collides shifting the position of the tip of Ude杆 of both the top runner is characterized in that the arm rod cross is made to overlap by the intersection.

According to a second aspect of the present invention, a runner roller provided with a pair of front and rear free rollers supported on both lower edges of a curtain rail is axially mounted via a support member, and an electric motor and a motor are mounted inside the runner roller. A drive roller interlocked with a drive shaft of the electric motor via a speed reduction mechanism is provided. The drive roller has a leading runner that moves by pressing against the lower surface of the curtain rail. The leading runner is disposed at both ends of the curtain rail. In a curtain electric opening / closing device for bringing the two leading runners closer to or away from both ends and opening / closing a curtain suspended by a large number of curtain hanging rings connected to the leading runner, The support member supporting the runner roller is axially attached to the base of the leading runner via an elastic member, and the axially attached portion of the leading runner is moved up and down. It said drive roller Te is curtains electric opening and closing device which is toward and away from the lower surface of the curtain rail.

Further, the object of the present invention is to provide an engaging hole for engaging a curtain suspension ring at a tip of an arm rod in front of one of the leading runners and a curtain at a tip of a crossing arm rod of the other leading runner. An engaging hole for engaging the suspension ring is provided, and at the position where the two leading runners collide with each other by shifting the tip positions of the arm rods of the two leading runners, the mutual arm rods intersect and overlap. A support member supporting the runner roller close to the drive roller is axially attached to the base of the leading runner via an elastic member, and the axially attached portion of the leading runner is moved up and down so that the drive roller is attached to the lower surface of the curtain rail. This can be achieved by a curtain electric opening / closing device that is adapted to come and go.

[0008] The electric curtain opening and closing device of the present invention has the above problem even when the curtain rail is extendable and retractable so that the length thereof can be adjusted, so that even an amateur at home can easily attach the window to any size window frame. Can be achieved, and
