Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vane angle control disc for an electric blind in which the vanes are raised, lowered and tilted by a drive shaft rotated by a motor.

Conventionally, in such electric blinds, four blades
In order to stop at a desired angle such as 50.900.135°, a complicated mechanism including multiple limit switches and control circuits corresponding to the desired angle was required.

An object of the present invention is to provide a blade angle control device that stops a blade at a desired angle with an extremely simple mechanism, and the blade is rotated by a motor to raise and lower and tilt the blade. A clutch drum is disposed around the drive shaft, and a vane angle control disc is rotatably mounted on the clutch drum, and between the disc and the clutch drum, when the vanes are tilted, both A clutch spring Y is arranged to connect the blades, but to interrupt the connection between the two when the blades are raised and lowered, and one or more actuating parts corresponding to the desired blade angle Pfr are formed on the disk, and The present invention is characterized in that it is provided with a switch that is operated by the operating section to stop the rotation of the motor.

The acid will be explained below with reference to the drawings.

FIGS. 1 and 2 show a lifting and tilting device N for a sleeper-type blind equipped with a vane angle control device according to the present invention. In the figures, 1 denotes a head box of the blind;
2 is a blade plate for the blind, 3 is a ladder cord that supports the filter plate, 4 is a lifting cord that raises and lowers the Vs plate, 5 is a drive shaft that raises and lowers the vane and tilts it, and 6 is a motor that rotates the drive shaft. .

The upper end of the rudder cord 3 is placed over the moving drum 7, and the upper end of the elevating cord 4 is attached to the elevating drum 8, and the motor 6 rotates the drums 7 and 8 to raise and lower the vane. It is configured to perform movements. 9 shows an embodiment of the wing plate angle control device h- according to the present invention. As shown in an enlarged view in FIG. 3, this g-turn angle control device 9 includes a frame 10 fixed within the head box 1, and a clutch supported within the frame and fixed on the drive shaft 5. A drum 11 and a vane angle control disc 12 rotatably mounted on the clutch drum connect the disc 12 and the clutch drum 11 when the vane 1 is rotating, but when the vane is moving up and down. A clutch spring 13 is provided to disconnect and disconnect the two. In the illustrated example, the clutch springs 13 are arranged on both sides of the disc 12, and act in opposite directions depending on the direction of rotation of the drive shaft 5. can achieve the purpose of

As clearly seen in the exploded perspective view of FIG. 4, the clutch spring 13 is engaged at one end 13a in the cutout groove of the disc 12. Further, the other end portion 13b of the H spring protrudes in the radial direction, and is provided inside the frame 1o so that when the disk 12 rotates until the rotation of the wing plate reaches the final position, as described later, 1. Protrusion 14a and 1.
4b is provided.

In the blade angle control disk 12K, a single actuating part of the sand is formed corresponding to a desired blade angle, and a limit switch is provided which is actuated by this actuating part to stop the rotation of the motor. provided. In the illustrated embodiment, the vane plate P1 is configured to be sub-tubed at Do, 48°, 900.135', 1800, and 450° on the side of the disk 12.
．． 90°, 135cYC equivalent position 2 action tiles 1
5 is formed, and the limit switch 1 has an arm that is activated by being engaged with these recesses Pgr15.
6 is provided.

Next, Fig. 5, which briefly explains the above-mentioned tearing operation, is as follows.
The control panel for the blinds above is shown.

For example, if the blade angle is to be set to 90 degrees, that is, to a horizontal device, the knob 17v900 on the control panel is set. The motor 6 is then activated to drive the drive 111dl.
5', and the disk 12 is rotated together with this rotation. When the vane rotates to the 90° position, the tip of the arm of the corresponding limit switch 16 enters the recess 15, stopping one rotation of the motor, and the vane stops around this.

Next, if you want to set the vane plate yic''135°V (, just set the knob 17 to the 165° position. As a result, the motor 6 is driven as before,
Rotate the drive shaft 5 degrees to bring the vane to the desired position. Here, the motor is stopped by the action of the limit switch, and the blade plate is stopped at this position.When raising and lowering the plate, the rotation of the blade plate is controlled by the drive shaft 5 until it reaches the final position. When the plate 12 is rotated, as shown in FIG.
The end of the clutch spring 13 comes into contact with the protrusion 14a or 14b in the frame 10, and the subsequent rotation of the drive shaft 5 works to loosen the clutch spring 13'7:, so the vane angle control circle The plate 12 and the clutch drum 11 are in a 7-lead configuration, so that the rotation of the driving kJJ axis is not transmitted to the control disk, and the lifting drum is rotated to raise and lower the blind blade plate. As described above, the present invention Lifting/lowering and tilting of the board 11711%j In an electric blind of the type that is operated by a single drive shaft, it is an extremely simple mechanism,
The blades can be stopped and moved as desired, and the blinds can be moved outside.Therefore, there is no need for a recovery mechanism or complicated circuits as in the past, so there are fewer failures.
This provides blade angle V control drawing at low cost.
