Description

Motorized louver system

The present invention relates to an electric louver system, and more particularly, there is no play between the slats and the slats, so the light blocking effect is excellent, and since the rotation of the slats rotates smoothly by the bearings, there is no noise and jamming phenomenon so that the convenience of operation. This is outstanding.

In general, louver systems are widely used to control the amount of light and air radiated from the outside to the interior by separately installing doors, windows, ceilings and roofs.

1 is a schematic diagram of a conventional passive louver system. As shown in FIG. 1, the conventional louvered louver system includes a window frame 1, a slat 2, and a plurality of connecting frames 1a.

Since the connecting frame (1a) is separated from each other, in order to open and close the slats (2) of each window, the corresponding handle (3) must be mounted to each connecting frame (1a).

Therefore, in the manual louver system, in order to open or close all the slats 2, there is a disadvantage in using the user to operate each handle 3 separately.

In order to overcome the disadvantages of the passive louver system, a louver system has been developed that can open and close all slats 2 simultaneously as an automatic louver system.

Conventional automatic louver systems are also complicated and not beautiful because the louver connection device is mounted on the outside, and in particular, the louvers are limited in the opening angle of each slat, so that it is difficult to control the light or air volume desired by the user. Since the slat rotates at a limited angle, there is a problem that periodic cleaning work for the slat is also difficult.

The present invention has been made in consideration of the various problems as described above, the object of which is to facilitate the rotation of the slats and at the same time there is no play between the slats to complete the light blocking, as well as structurally simple and convenient operation It is to provide an electric louver system that is easy and easy to maintain and repair.

In order to achieve the above object, a guide rail is provided to provide a predetermined space so that a plurality of gear bodies are arranged in a row, and is connected to the gear belt while being installed inside the guide rail and has an insertion groove on one side. In the center, a gear is formed on the outer circumferential surface of the upper surface and a main rotating shaft having a coupling protrusion having a cutting groove at the bottom thereof is inserted therein, and a gear body provided with a plurality of auxiliary rotating shafts formed in multiple stages on both sides of the main rotating side, On the upper surface of the slat fixing plate is installed in contact with the outer surface and the gear belt formed gears in a constant arrangement on the inner surface, the slat fixing plate having a fixed plate is fastened to the coupling projection of the main rotation shaft, the fastening projection is formed in the center of the bottom surface, Constructed with slats installed and rotating 360 °

The present invention as described above has various effects as follows.

The first is that the rotation of the slats is smooth, and the operation is convenient.

Second, there is no play between the slats, so the effect of light blocking is excellent, thereby reducing the heat loss inside.

Third, the structure is simple and easy to install and install, which has the advantage of excellent economic efficiency.

Hereinafter, described in detail with reference to the accompanying drawings for the practice of the present invention will be described.

2 and 3 are views showing in detail the overall configuration of the electric louver system to which the present invention is applied, in which reference numeral 100 denotes a main body of the electric louver system according to the present invention.

The main body 100, the guide rail 10, the main body shaft 20 and the auxiliary rotation shaft 30, the gear body 40, the gear belt 50, the slat 70 is fixed to the upper slat It consists of a fixed plate 60.

The guide rail 10 is formed of a metal material and has a predetermined space (11) so that the gear body 40 to be described later inside is arranged in a row, the support protrusion for supporting the gear body 40 on both sides of the upper ( 12) is formed to protrude to the outside. And the guide hole 13 is formed long in the longitudinal direction in the upper center.

The gear body 40 has a rectangular shape made of a synthetic resin material as shown in Figures 4 to 7 attached to the main gear shaft 41 and the main rotating shaft (installed with the main rotating shaft 20 and the auxiliary rotating shaft 30) 20) is divided into the auxiliary gear body 42 is installed only.

The main gear body 41 has an insertion groove 42 in which a gear belt 50 is inserted at one side of an upper surface thereof and forms an insertion hole 43 in which a main rotation shaft 20 is inserted in the center thereof.

At this time, the bearing 44 is installed on the outer circumferential surface of the insertion hole 43 as shown in the accompanying drawings so that the rotation of the main shaft 20 is made smooth.

And in the lower center of the main gear body 41, the U-shaped guide groove 45 is formed.

As shown in FIGS. 5 and 7, the auxiliary gear body 47 has an insertion hole 43 into which a main rotation shaft 20 is inserted in the center thereof, and a guide groove 45 having a U shape in the lower center thereof. Formed.

The bearing 44 is also installed in the insertion hole 43 of the auxiliary gear body 47 to smooth the rotation of the main rotation shaft 20.

* The main rotating shaft 20 has a gear 21 is formed at regular intervals on the upper outer circumferential surface, the cutting groove 23 is formed in the center of the lower end and the coupling projection 24 formed to penetrate the bolt hole 25 on both sides Has

The coupling protrusion 24 is smaller in diameter than the main rotation shaft 20 and is installed in the insertion hole 43 of the gear body 40 to be exposed to the outside.

At this time, the upper surface of the main shaft 20 is in contact with the bearing 44 formed in the insertion hole 42, so that the rotation of the main shaft 20 is smooth.
