Description

[Detailed Description of the Invention] This invention is an improvement in the attachment part of the limit switch which is attached near the curtain opening/closing end of the curtain rail.

The above-mentioned limit switch is generally fixed to the top surface of the curtain rail by screws or other means via a bracket or the like, but with such means, there is little space above the curtain rail after it is installed. In this case, it was difficult to operate a screwdriver for installation, and even after installation, it was inconvenient to move the installation position or attach/detach.

This invention was devised for the purpose of obtaining a curtain opening/closing switch that does not have the above-mentioned drawbacks.The structure is explained with reference to the drawings. Figure 1 is a front view of one embodiment of the curtain opening/closing switch of this invention, and Figure 2 is a rear view. Figures 3 and 3 are bottom views, and Figure 4 is a perspective view of the seat plate 1.
Protruding arms 2 are provided on the rear left and right sides, and downward folding edges 3 are formed at the rear ends, rearward notches 4 are provided on the front left and right sides to form left and right seat parts 5 and an intermediate seat part 6 separately, A receiving plate 7 is superimposed on the lower surface of the left and right seat portions 5, and a long hole 8 in the front and rear direction is bored in the center of the receiving plate, and a screw 9 is inserted through the hole from below toward the seat portion 5.
to fasten. Note that a hanging side 10 is provided on one side of the receiving plate.

The middle seat part 6 is separated from the left and right seat parts 5, and a switch case 15 is attached to the lower surface thereof. A normally closed limit switch 16 is housed in the case, and a movable button 17 of the switch is projected near the lower center of the seat plate 1. 18 indicates a lead-in line to the switch.

5 and 6 are a side view and a bottom view showing the usage state of the curtain opening/closing switch according to the present invention, and 21 is a curtain rail having ears 22 on both sides of the top plate; 23
24 is a vertical groove in the center of the lower surface of the rail, 24 is a curtain leading runner that advances and retreats along the rail, and 25 is a switch push plate provided on the side surface of the runner.

To attach the proposed switch to a curtain rail, loosen the screw 9, insert the left and right protruding arms 2 above the top plate of the curtain rail 21 as shown in FIG. It is only necessary to hang it, push the rear edge of the receiving plate 7 below the other ear part 22B of the rail, engage it, and then tighten the screw 9.

Next, the effect will be explained.

As shown in FIG.
When the button 17 is pressed, it opens the normally closed switch and stops the runner. If the runner tries to advance further due to inertia after the switch is opened, the front end of the push plate 25 will hit the hanging side 10 and be stopped, so the push plate 25 will move forward when the button 17
There is no possibility that the curtain will be closed by passing over the curtain and moving forward to close the switch again.

When the curtain opening/closing switch of this invention is attached to a curtain rail, it is only necessary to insert the flat plate-shaped protruding arm 2 above the top plate of the rail.
It can also be used for rails installed close to the mounting surface, and the screws 9 are tightened by inserting a screwdriver from below, making it easy to switch even if the rail is installed inside a curtain box, etc. It has the advantage of being able to be attached, detached, and moved.
