Description

[0001] The present invention relates to a multifunctional blind operated by automatic illumination and humidity sensing,

The present invention relates to a blind installed in the vicinity of a window of a home or an office or the like to cover the entire window or cover only a part of the window as needed to serve as a ventilation and awning. More specifically, It is maximized convenience by automatically controlling the operation according to the amount of sunlight irradiated through the window.

In addition, it is possible to smoothly operate the motor by suppressing the occurrence of motor overload, and to maintain the straightness so that the blind can be accurately controlled. In addition, it is possible to smoothly and precisely operate the rotary system by long- It is a technology that enables automatic operation according to brightness.

Generally, blinds are widely used for the purpose of exhibiting an awning function and an indoor privacy function by being installed in a window of a home or an office.

The performance required for the blinds is that it allows easy visualization of ventilation, indirect light, and a certain degree of visibility while blocking direct sunlight or an external visual line, and that it can easily be removed and removed when not needed.

On the other hand, a blind is a shape in which a rectangular thin cover plate is arranged in parallel, and the light beam can be shielded by changing the angle of the cover plate.

Such conventional built-in electric blinds are difficult to precisely adjust the timing when the power of the driving apparatus is cut off at the upper and lower limit positions of the blinds in accordance with the respective window lengths, so that the installation time is long and the long- .

In addition, the conventional built-in type electric blind not only can not accurately detect the winding amount of the rope for lifting and lowering, but also causes overload to shorten the service life of the motor and even damage the winding portion.

Therefore, it has been demanded to develop a more excellent device by continuously operating the smooth blind in the window with the large electric blind

In particular, in the case of being built in a large electric blind window, since the head box must be installed in the lateral direction, the straightness of the rotated shaft is reduced, which causes an overload in the motor, which shortens the life of the motor and even damages it .

In addition, the conventional blind has a complicated structure and a relatively wide front / rear width, so that when the blind is used as a built-in type of double window, the thickness of the double window becomes thick.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the problems of the related art,

The upper and lower limit positions of the blinds can be accurately set, and the blinds can be smoothly operated, thereby improving work efficiency and reliability.

Also, even when installed in a large window, the straightness of the rotation of the shaft can be maintained to be excellent, thereby preventing overload of the motor and extending the service life.

In addition, when the blind is folded, the blind can not be seen from the outside, so that the appearance can be treated neatly.

Also, it is possible to maximize the convenience by allowing the blind to operate automatically by using the illumination sensor.

And it simplifies the structure and minimizes the width of the front and rear to minimize the thickness of the installed double blind so that the double blind can be manufactured.

The multifunctional blind which is automatically operated through the illumination and humidity automatic detection of the present invention is a multifunctional blind which automatically rotates the shaft 113 by combining the speed reducer 112 with the motor 111 to reduce the rotational force to a proper number of rotations, A drive supply unit 110 for selectively controlling the operation of the motor 111 by connecting the shaft 113 of the drive supply unit 110 to the rear end and a prismatic adjustment shaft 153 at the front end thereof, A flexible joint 150 in which a spiral slit 152 is formed on an outer circumferential surface and a front end of an adjustment shaft 153 of the flexible joint 150 are connected to a prismatic hole 143 formed in a rising drum 141 A spiral support 148 is formed on the outer circumferential edge of the lifting drum 141 to form a spiral portion 142 and a screw hole 149 for screwing and supporting the spiral portion 142, A plurality of lifting and lowering drums 141 are connected and a plurality of lifting and lowering drums 141 And a shaft 124 is coupled to the front end of the ascending and descending drum 141 of the actuating part 140 and the shaft 124 is coupled to a worm A power transmitting portion 120 forming a worm 121 in the longitudinal direction and having a worm wheel 122 vertically erected and coupled to the lower side of the worm 121 with a planetary gear 123 formed on the worm wheel 122, And a pair of swing arms 133 are fastened to the center shaft 132 formed on the other side of the sun gear 131 and fixed to the planetary gears 123 of the transmission unit 120 by gear- A control unit 130 for controlling the upward and downward movement of the swing arm 133 by providing a pair of limit sensors 135 corresponding to the upper side of the swing arm 133 and a control unit 130) Operation part 140 A transmission part 100 composed of a flexible joint 150 is installed on the upper side of the inside and the lower part of the lower part of the blind 1, It is composed of a support frame 40 that forms a cross.

The drive supply unit 110 integrally includes a reduction gear 112 on the motor 111 so that the rotation speed of the motor 111 can be reduced to an appropriate rotation speed.

Here, the illuminance sensor of the driving supply unit 110 may be configured to automatically control the motor 111 according to the brightness of the outside using a variable resistor or a switching device, Do.

The flexible joint 150 has a cylindrical shape and is formed with a shaft hole 151 penetrating right and left, and a screw-shaped spiral slit 152 is formed on the outer periphery to have a certain elasticity

Here, it is preferable that a hexagonal shape is formed by coupling a rectangular adjustment shaft 153 to the front end of the flexible joint 150.

The actuating part 140 sequentially connects a plurality of lifting and lowering drums 141 in the longitudinal direction to the adjusting shaft 124 of the flexible joint 150 and sequentially connects the lifting and lowering drums 141 to the connecting shaft 147).

Here, the shaft hole 143 is formed with a hexagonal hole in the ascending and descending drum 141 on the flexible joint 150 side.

In addition, the gap between the lifting drum 141 and the lifting drum 141 is connected by a shaft 147, and a flexible adhesive is filled in the connecting portion to maintain a slightly flexible state in the joint portion, It is preferable to improve the straightness of the shaft so as to suppress the occurrence of an overload in the members such as the motor 111 and the like.

Further, it is preferable that the lifting wire 30 is coupled to the lifting drum 141 and at least one support 144 is provided at the lower side.

In addition, a tilt adjuster 145 having a guide groove 146 formed therein is coupled to one side of the outer periphery of the ascending and descending drum 141, and the upper side of the ladder-shaped pivoting guide wire 20 is fixed thereto.

Further, the tilt adjuster 145 is installed to have a constant frictional force on the ascending / descending drum 141, idling when rotating at a high speed, and interlocking at a low speed.

In detail, when the blind 1 is lifted and lowered, the lifting and lowering drum 141 rotates at a high speed, so that the tilt adjuster 145 is kept stationary, and the blocking louver 10 of the blind 1 When the degree of light transmission is adjusted by adjusting the angle of the shielding plate 11, the tilt adjustor 145 is rotated by the friction force due to the rotation of the lifting drum 141 at a very slow speed, 11 are adjusted.

In fact, since the angle of rotation is very fine, the left and right angles are 85 °, so there is little change in the height of the blind 1.

Preferably, the power transmission unit 120 can minimize the width by gearing the worm wheel 122 vertically to the lower side of the worm 121.

Here, the planetary gear 123 is formed on one side of the rotation shaft of the worm wheel 122.

In addition, since the ascending and descending drum 141 is connected to the shaft 124 of the power transmitting portion 120 in the longitudinal direction, a structure for simultaneously performing the rotational motion and the linear motion is adopted. So that the elevating wire 30 can be wound or unwound in the form of a coil on the lifting drum 141 so that the blind 1 can be raised and lowered accurately.

It is preferable that the control unit 130 can minimize the width by vertically erecting the sun gear 131 formed with the gears in an internal shape and engaging the planetary gear 123 formed on the rotary shaft of one side of the worm wheel 122 .

Here, a plurality of guide rollers 134 are installed on the outer circumference of the sun gear 131 so that the sun gear 131 is set at a correct position and smoothly rotated, while the guide roller 134 is coupled to the head box .

In addition, the headbox is preferably formed so that the internal components can be perfectly positioned after assembly

Further, a center shaft 132 is formed on the opposite side of the internal gear of the sun gear 131, and a swing arm 133 for controlling the up and down movements of the center shaft 132 is fixed at an accurate position.

The limit sensor 135 is provided on the upper side of the sun gear 131 so as to correspond to each of the swing arms 133 so that the covering louver 10 of the blind 1 is completely lowered One swing arm 133 is set on the center shaft 132 of the sun gear 131 and the blind louver 10 of the blind 1 is in a completely raised state (in the folded state) Since the one swing arm 133 is set on the center axis 132 of the sun gear 131 to fix them completely, the operator blind 1 can be easily and quickly installed, Prevent overload.

In this configuration, when the motor 111 is controlled to raise or lower the covering louver 10 of the blind 1, it is transmitted to the worm 121 by the rotary sequence while rotating at a proper rotation speed through the reducer 112 At the same time, the ascending and descending drum 141 coupled in the longitudinal direction of the rotating series rotates or reversely rotates to raise and lower the covering louver 10 to a desired position.

At this time, when the desired position is reached, the power of the motor 111 is cut off and the operation is stopped.

When the blind 1 is folded to the uppermost side or spreads to the lowermost side, the above-described operation is continuously performed, and the worm wheel 122 vertically engaged with the upper side of the worm 121 by the continuous rotation of the worm 121 The integral planetary gear 123 is rotated and the sun gear 131 coupled to the planetary gear 123 is also rotated.

The swing arm 133 coupled to the center shaft 132 of the sun gear 131 presses the limit sensor 135 to open the cover louver 10 of the blind 1 in a fully extended state or in a completely folded state, The supply is shut off to stop the operation, thereby protecting the motor 111 from overloading.

Furthermore, even when the limit sensor 135 is formed on the upper side and used for a long period of time, there is almost no influence on the weight, so that it always operates reliably.

In this case, when the blind 1 is folded to the uppermost side, the folded state of the blind 1 can not be visually observed from the outside because it is folded into the inside of the support frame 40. As a result, do.

On the other hand, the tilt adjuster 145 remains stopped even when the ascending / descending drum 141 rotates.

When the angle of the shielding plate 11 constituting the blind louver 10 of the blind 1 is adjusted to adjust the degree of light transmission or the like, the motor 111 is rotated at a low speed so that the rotational force transmitted from the speed reducer The angle of the shield plate 11 is adjusted because the tilt adjuster 145 is rotated by the friction force with the lifting drum 141.

Actually, the rotation angle is 170 deg. Overall, and the rotational force is very minute. Therefore, there is almost no change in the height of the blind 1 already set.

The motor 111 and the flexible joint 150 are connected to each other and the shaft 147 between the ascending and descending drum 141 and the ascending and descending drum 141 is filled with a soft adhesive. The overload of the motor 111 can be suppressed, and the overload of the motor 111 can be suppressed.

On the other hand, when the outside is somewhat darkened by the illumination sensor, the variable resistor is turned on or off or the switching element is turned "on " or off to control the motor 111 to rotate or reverse to fold or unfold the blades .
