Description

[Detailed description of the invention] This invention is an improvement of the power transmission cord wiring part of the electric curtain opening/closing device.

A specialized electrician is required to attach the power transmission cord between the motor of the electric curtain opening/closing device and the limit switch along the curtain rail to the mounting surface. In the case of wiring the cord or rail, there are disadvantages such as not only the cord or the cord being exposed or hanging down on the outer surface of the rail, which makes the cord look unsightly, but also causing a malfunction if something else gets caught on it.

The present invention was devised for the purpose of obtaining a wiring device for a curtain rail without the above-mentioned drawbacks, and its configuration will be explained with reference to the drawings. Figure 1 shows an example of a curtain rail equipped with the wiring device of the present invention. A perspective view, FIG. 2 is a side view of the spacer attachment part, and FIG. 3 is a bottom view of the spacer.

The wiring device for a curtain rail according to the present invention will be explained with reference to the drawings. It includes a curtain rail 1 having ears 2A and 2B on both left and right sides of the top, a spacer 11 disposed on the top of the rail, and a power transmission cord wired on the top surface of the curtain rail 1. The spacer 11 is formed by forming the front and rear parts of the top plate into two high and low levels, pulling the front end of the high step part 15 down to a level below the level with the low step part 16, and then bending it inward to attach the spacer 11 below the ear 2A on one side of the rail. An insertion line 17 is formed on the lower surface of the high step section 15 by forming an insertion line 17 on the left and right sides of the low step section 16 so that the upper end thereof is flush with the high step section 15. 15
Drill a hole 19 for a mounting screw in a part of the lower part 16.
Insert plate 20 below the ear 2B on the other side of the rail.
The power transmission cord 14 is inserted into the space 13 during wiring.

Next, to explain the effect, the above-mentioned spacer 1
1 to a mounting surface such as a ceiling, and after fixing the mounting screws 18 to the receiving holes 19, attach the ears 2 on both sides of the rail below the high step part 15 and above the insertion edge 17 and the insertion plate 20.
When A and 2B are inserted and the screws 21 are tightened from the bottom of the insertion plate toward the low level part, the rail 1 is secured by the spacer 11, and there is a gap between the lower surface of the high level part 15 and the top surface of the rail top plate. Since a recess 13 is formed, if a power transmission cord 14 mounted and wired on the top surface of the rail is inserted into this recess, the cord is secured on the rail surface.

According to the present wiring device, the power transmission cord to the limit switch placed on the top surface of the curtain rail 1 can be easily inserted into the wide space under the spacer of each part without damaging the cord during work, and Since the cord is held precisely, there is no risk of it moving or escaping out of the rail, and the cord looks good and there is no risk of failure. Furthermore, since this wiring does not have a fixing structure for the cord, it also has the advantage of not requiring a qualified electrical engineer for legal and practical construction purposes.

Claims (1)

[Scope of utility model registration request] It consists of a curtain rail 1 having ears 2A and 2B on both the left and right sides of the top, a spacer 11 disposed on the top of the rail, and a power transmission cord wired to the top surface of the curtain rail 1. The spacer 11 connects the front and rear of the top board in height The front end of the high step part 15 is pulled down from a position flush with the low step part 16, and then bent inward to insert the edge 1 downward of the ear 2A on one side of the rail.
7 is formed, and rising sides with upper ends flush with the high step part 15 are provided on the left and right sides of the low step part 16 to form a space 13 on the lower surface of the high step part 15, and a part of the high step part 15 is A mounting screw receiving hole 19 is drilled, and an insertion plate 20 for lowering the ear 2B on the other side of the rail is screwed to the lower surface of the low step part 16, and the power transmission cord 14 is inserted into the space 13 when wiring. This is a wiring device for curtain rails.
