The ceiling blinder according to an embodiment of the present invention includes a winding device including a first chain gear integrated at an intermediate portion of a first shaft supporting the first rolling gear, and a rotation roll integrated with the other end of the first shaft and winding the blinder. And a timing belt meshing with the first chain gear of the winding device and having a tooth formed therein, the same gear as the first chain gear of the winding device, and having a hollow formed at the center thereof so that the second shaft penetrates through the hollow.

According to the ceiling blinder according to an embodiment of the present invention, the manufacturing cost is low and the production process is shortened, thereby reducing the production equipment and labor costs.

Hereinafter, the configuration and operation exerted by the ceiling blinder according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view schematically showing the configuration of a ceiling blinder according to an embodiment of the present invention.

As shown in FIG. 1, referring to FIG. 1, a ceiling blinder according to an embodiment of the present invention includes a winding device 10. The winding device 10 includes a first shaft 11 for supporting the recommended value 10, a first chain gear 12 integrated at an intermediate portion of the first shaft 11, and a first shaft 11. And a rotary roll 13 which is integrated with the other end of and winds up the blinder 30.

The power transmission device 20 has a timing belt 21 engaged with the first chain gear 12 of the winding device 10 and a second gear having the same gear as the first chain gear 12 of the winding device 10. Chain gear 22.

A gear 23 is formed on the inner surface of the timing belt 21 of the power transmission device 20.

The second chain gear 22 has a hollow (without reference numeral) formed at the center thereof, and the second shaft 5 penetrates through the hollow to be fixed to the guide rail body (not shown).

The gear of the first chain gear 12 of the winding device 10, the gear 23 ′ of the timing belt 21 of the power transmission device 20, and the second chain gear 22 of the power transmission device 20. The gears are designed to be set to 2πR / 8 to 2πR / 12, respectively, when the radius of the rotary roll 13 of the winding device 10 is R.

In other words, the first chain gear 12 of the winding device 10 and the timing belt of the power transmission device 20.

21 and the second chain gear 22 of the power train 20 have a distance between the valleys and valleys or the hills and hills in their respective gears, the radius of the rotary roll 13 of the take-up device 10. In the case of R, they are 2πR / 8 to 2πR / 12, respectively.

The gears of the first chain gear 12 of the take-up device 10, the timing belt 21 of the power transmission device 20, and the second chain gear 22 of the power transmission device 20 are respectively wound. The setting of 2πR / 8 to 2πR / 12 on the basis of the radius R of the rotary roll 13 of 10) indicates that the length of the blinder 30 wound or unwound by the rotary roll 13 is the power transmission device 20. ) Is equal to the length of advancing or reversing by the timing belt.

Therefore, the blinder 30 wound or unwound by the rotary roll 13 in accordance with the rotation of the motor 1 proceeds in line with the traveling speed of the timing belt 21 of the power transmission device 20 and thus remains taut.

The first shaft 11 of the winding device 10 is coupled to the motor shaft 2 by the motor gap housing 3.

Thus, when the motor 1 is driven, the motor shaft 2 is rotated and thus the first shaft 11 is also rotated through the motor gap housing 3.

Subsequently, as the first shaft 11 rotates, the first chain gear 12 of the winding device 10 integrated with the first shaft 11 and the rotation roll 13 of the winding device 10 also rotate.

In addition, the rotational force of the first shaft 11 integrated with the first chain gear 12 of the winding device 10 is transferred to the second chain of the power transmission device 20 through the timing belt 21 of the power transmission device 20. Gear (22)

Is passed on.

Thus, the second chain gear 22 of the power train 20 also has a second shaft in accordance with the rotation of the motor 1.

It will rotate about (5).

The motor 1 can be rotated forward or reverse.

The plastic bar 40 is attached to the lower end of the blinder 30. It is fixed. One end of the bar 40 is attached to and fixed to a part of the side surface of the timing belt 21 of the power train 20.

Thus, as the timing belt 21 of the power transmission device 20 moves forward or backward in accordance with the rotation of the motor 1, it is attached to a part of the side surface of the timing belt 21 of the power transmission device 20. Since the bar 40 is fixed, the bar 40 is pulled firmly while moving forward or backward with the timing belt 21 of the power transmission device 20.

If the motor 1 rotates forward, the blinder 30 is unfolded because the timing belt 21 of the power transmission device 20 advances in the forward direction. On the contrary, when the motor 1 reversely rotates, the blind belt 30 is folded because the timing belt 21 of the power transmission device 20 moves backward. This is a circuit design problem and can be set vice versa. That is, when the motor 1 rotates forward, the blinder 30 may be folded, and when the motor 1 reversely rotates, the blinder 30 may be unfolded.

When the user supplies power through a switch (not shown) to adjust the ceiling blinder installed in the ceiling, the motor 1 rotates. At this time, the forward rotation or the reverse rotation of the motor 1 is determined by the operation of the switch.

If the user tries to block the sunlight coming through the ceiling window by unfolding the ceiling blinder installed in the ceiling, the user causes the motor 1 to rotate forward through the operation of the switch.

When the motor 1 rotates forward, the shaft 11 also rotates forward, and at the same time, the first chain gear 12 and the rotation roll 13 also rotate forward.

As the first chain gear 12 rotates forward, the timing belt 21 also rotates forward. As the second chain gear 22 engaged therewith also rotates forward, the timing belt 21 moves forward. .

The timing belt 21 proceeds in the forward direction and is attached to the bottom end of the blinder 30. The fixed bar 40 also proceeds in the forward direction.

As a result, when the motor 1 rotates forward, the rotation roll 13 also rotates forward, and is attached to the lowermost end of the blinder 30. The fixed bar 40 also proceeds in the forward direction.

Forward rotation of the rotary roll 13 and advancing in the forward direction of the bar 40 releases the blinder 30 wound on the rotary roll 13 and pulls out the released blinder 30 in the forward direction.

Therefore, the blinder 30 wound around the rotary roll 13 is loosened and attached to the bottom end of the blinder 30. When the fixed bar 40 reaches the second chain gear 22, the rotation of the motor 1 is stopped. And as the bar 40 reaches the second chain gear 22, the bullliner 20 is fully extended to cover the ceiling window. Thus, the blind 30 blocks the sunlight entering through the ceiling window.

On the other hand, when the user wants to fold the blinder 30 blocking the sunlight coming through the ceiling window, the user may operate the switch in the opposite manner as described above.

If the user wants to kick off the blinder 30 blocking the ceiling window, the user causes the motor 1 to reverse by operating the switch.

When the motor 1 rotates in reverse, the shaft 11 also rotates in reverse, and at the same time, the first chain gear 12 and the rotation roll 13 also rotate in reverse.

As the first chain gear 12 reversely rotates, the timing belt 21 also reverses, and the second chain gear 22 engaged therewith also reversely rotates so that the timing belt 21 moves backward. .

The timing belt 21 proceeds in the reverse direction and is attached to the lowermost end of the blinder 30. The fixed bar 40 also proceeds in the reverse direction.

As a result, when the motor 1 rotates in reverse, the rotation roll 13 also rotates in reverse and is attached to the lower end of the blinder 30. The fixed bar 40 also proceeds in the reverse direction.

The reverse rotation of the rotary roll 13 and advancing in the backward direction of the bar 40 wind the blinder 30 loosened on the rotary roll 13 and pull the unopened blinder 30 in the reverse direction.

Therefore, the blinder 30 loosened on the rotary roll 13 is wound up and attached to the lowest end of the blinder 30. When the fixed bar 40 reaches the first chain gear 12, the motor

Rotation of (1) is stopped. And as the bar 40 reaches the first chain gear 12, the bullliner 20 is completely folded to open the ceiling window. Thus, sunlight enters through the ceiling window by the blinder 30.

1 is a perspective view schematically showing a configuration of a ceiling blinder that can be driven by one axis according to an embodiment of the present invention.
