Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sunshade blind device, and more particularly to a novel blind device that can appropriately adjust the intensity of light rays indoors or in a car.

[Conventional technology]

With the advancement of science and technology and the improvement of living standards, safety, speed, and comfort have become the principles of people's lives. Conventional sunshade blinds used indoors or in cars include, for example, Venetian blinds using slats or curtains made of cloth. And these certainly have a sunshading effect.

[Problems that this invention attempts to solve]

However, the comfort of living in the conventional one,
Even if simplicity and convenience are assumed, there are still drawbacks as listed below.

(1) In conventional sunshade means such as curtains,
They tend to make noise and flip when the wind blows.

(2) When this type of sunshade is fully closed, the incoming light beam is the strongest and often makes your eyes sting, and when it is fully closed, the incoming light beam is the weakest and can cause indoor damage. It is easy to get eyelashes. Therefore, when it is half-opened, the incoming light rays are unevenly distributed, which is not ideal in terms of lighting.

(3) Many of these sunshades use cords to control opening and closing.
Often, when opening/closing, each code is mistakenly entered, making it easy to operate.

(4) Such a sunshade means is difficult to be said to be a sufficiently popular sunshade means because of its high manufacturing cost.

Next, when it comes to sunshading methods used inside cars, most of them are deep-colored anti-light sheets or hand-drawn curtains, and while they do have a sunshading effect, they have the following drawbacks: still exists.

(1) When the sun is strong, the deep-colored anti-reflective sheet
It works well as a sunshade, but when you back up your car at night (especially when you back up on a rainy night), the amount of light is extremely reduced, which significantly obstructs your visibility and impairs safe driving. In addition to causing this, it can also cause accidents.

(2) A deep-colored anti-light sheet has a fixed color, is difficult to peel off once attached, and cannot adjust the amount of light inside the car.

(3) The guide curtains do have a sunshading effect, but since they are based on the guide, it is necessary to be careful when driving.
It is difficult to open and close the curtains by hand due to distraction, which is not very practical.

(4) When the guide curtains are fully open, they emit the most amount of light, which can be blinding, and when they are closed, the amount of light is the least, and the inside of the car tends to get dark. Therefore, the curtains must be adjusted during the day and at night, and must be adjusted frequently depending on the weather conditions, which is very troublesome.

The present invention was made against the background of the above-mentioned circumstances, and an object of the present invention is to provide a novel blind structure that can appropriately adjust the amount of light indoors or in a car.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention is a new blind structure, which includes two sets of cradles fixed to the window frame, and two sunshades each pivotally supported on the cradles. a sunshade sheet having one side fixed to the sunshade rod and the other side fixed to the other sunshade rod, the length of which is longer than the distance between these two sunshade rods; and a driving means for winding up and moving a sunshade sheet between two sunshade rods using an electric motor, wherein the sunshade sheet has an opening diameter along its longitudinal direction. The main idea is that a large number of lighting holes of different sizes are arranged from the smallest one to the largest one, and that the lighting hole of an appropriate size is moved to the window part by the driving means.

The driving means includes a pair of transmission pulleys fixed to the sunshade rod, a belt wound between these transmission pulleys, and a belt fixed to the window frame with an output shaft fixed to the sunshade rod. The invention is characterized in that it comprises an electric motor that is coupled to one of the sunshade rods to rotate the sunshade rod.

[Effect]

Based on the above-mentioned means, the present invention includes two sets of cradles, two sunshade rods that are pivotally supported on these cradles, and a sunshade rod that is stretched between these sunshade rods and that extends in the longitudinal direction. A sunshade sheet is provided with a large number of daylighting holes having different opening diameters from small to large, and an electric motor is used to wind the sunshade sheet between two sunshade rods. With a simple structure consisting of a driving means for taking and moving the light beam, the intensity of the incident light beam can be freely adjusted according to the actual needs of the interior of the room or the car.
It can be operated simply by switching the electric motor on, off, forward rotation, and reverse rotation.

Further, since a cylindrical cover is provided on each set of cradles, it is possible to cover the sunshade sheet wound around the sunshade rod.

Further, by interposing a bearing between each set of cradles and the sunshade rod, the sunshade rod can be rotated smoothly.

Further, by providing one or more sets of transmission pulleys and providing one or more belts wound between these transmission pulleys, rotational driving force is transmitted evenly.

In addition, the sunshade sheet has a large number of lighting holes with a constant opening diameter in each area along its longitudinal direction, and the opening diameter of the lighting holes opened in each area is increased or decreased sequentially to increase the effect. The amount of incident light is adjusted accordingly.

Further, the driving means includes a pair of transmission pulleys fixed to the sunshade rod, a belt wound between these transmission pulleys, and an output shaft fixed to the window frame. and an electric motor that rotates the sunshade rod by being coupled to one of the sunshade rods, thereby winding up and moving the sunshade sheet stretched between the sunshade rods. .

The driving means includes a spiral spring wrapped around one sunshade rod and an electric motor whose rotational driving force rotates the other sunshade rod, so that the electric motor can be operated correctly. When rotating, the sunshade sheet is wound onto another sunshade rod that is not wrapped with a spiral spring, and when the electric motor reverses, the repulsive force of the spiral spring causes the sunshade sheet to be wound around the other sunshade rod. By winding the spiral spring onto the sunshade rod, it is possible to freely select a lighting hole with an appropriate opening diameter on the sunshade sheet.

Further, by using a transparent plastic sheet as the sunshade sheet and changing the color from light to deep, the amount of incident light can be adjusted appropriately.

In FIG. 1, when the electric motor 10 is turned on and the sunshade rod 3 connected to the output shaft 101 is rotated, the transmission pulleys 6 and 7 fixed on the sunshade rod 3 also rotate at the same time. As a result, the lower sliding pulleys 6, 7 and the sunshade rod 4 are also rotated via the belts 8, 9. Therefore, depending on the amount of light required indoors or inside the car, the electric motor 1
By rotating the sunshade sheet 5 in the normal or reverse direction, the sunshade sheet 5 can be quickly rolled up and moved and stopped at an appropriate position. Light rays from the outside enter the interior of the room or the car through the lighting holes 51 provided on the sunshade sheet 5, but the opening diameters of the lighting holes 51 are different in size, and the sunshade sheet 5 is flexible and By being quickly rolled up and moved, the necessary amount of light can be obtained indoors and in cars.

In addition, especially when opening/closing or cleaning windows, the sunshade sheet 5 is rolled up as far as it will go on the upper sunshade rod 3 by operating the switch of the electric motor 10, and then The above work can be made easier by removing the rod 4 along with the tube cover 41 from the shaft support 21 of the cradle 2, and further rotating the electric motor 10 to pull the tube cover 41 below the upper sunshade rod 3. I can do it.

Furthermore, FIG. 3 is a front view showing another embodiment of the present invention, in which the sunshade sheet 5 is divided into two parts, and one belt 8 is wound around one set of transmission pulleys 6. By doing so, the sunshade sheet 5 can be freely rolled up and moved in the same way.

The drive means constituted by the two sets of transmission pulleys 6, 7, two belts 8, 9, and the electric motor 10 described above winds the sunshade sheet 5 between the two sunshade rods 3, 4. This drive means is intended to provide a rotational driving force for picking up and moving, but as shown in FIG. 4, this driving means can also be constructed by combining the electric motor 10 with one spiral spring 91. That is, one inner end of the spiral spring 91 is fixed to the sunshade rod 3, and one outer end thereof is fixed to the solid plate of the cradle 1, so that the electric motor 10 rotates the sunshade rod 4. You can also do that. When the electric motor 10 rotates the sunshade rod 4, the sunshade sheet 5 is wound onto the sunshade rod 4, and at the same time, the sunshade sheet 5 wrapped around the sunshade rod 3 is pulled out. It can be done. At this time, the spiral spring 91 is wound, and the next time the electric motor 10 reverses, the unwinding force of the spiral spring 91 causes the sunshade sheet 5 to be wound onto the sunshade rod 3. . Therefore, the electric motor 10
By operating the forward/reverse direction of the sunshade sheet 5,
is wound up and moved to an appropriate position, and the amount of incident light can be adjusted by adjusting the opening diameter of the lighting hole 51.

Next, FIG. 5 is a front view showing yet another embodiment of the present invention, particularly a sunshade sheet 5, which is divided into sections along its longitudinal direction. It is made up of lighting holes with different opening diameters, the lighting holes in section B have a larger opening diameter than the lighting holes in section A, the lighting holes in section C have a larger opening diameter than the lighting holes in section B, and the lighting holes in section D have a larger opening diameter than the lighting holes in section D. The opening diameter of the lighting hole is larger than that of the lighting hole in section C. In this way, the amount of light entering the room or inside the vehicle can be adjusted as appropriate.
