Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a shutter that functions as both a blind and a shutter.

(b) Conventional technology and problems Conventionally, blinds have been attached to the inside of windows so that they can move up and down and can be opened and closed to provide sunshade, etc. However, in the summer, sunlight irradiates the blind slats. When the blind slats overheat, they cannot efficiently cool the room, and since the blind itself does not serve as rain protection or crime prevention, it is necessary to install a separate shutter. As a result, the structure of the rabbit-angle window has become complicated, which has led to problems such as it being difficult to install and use.

(C) Means for Solving the Problems In view of the above, the present invention provides a large number of blinds in which guide grooves are provided on the inner wall surfaces of the left and right guide tubes provided on the outside of the window frame, and V grooves are formed in the guide grooves. The left and right ends of the slats are fitted together, and the front and rear ends of a receiving piece fixed to the tip of the slat are connected at a predetermined interval to an extension of a chain wrapped around a drum that is rotated in forward and reverse directions by a motor installed above the guide cylinder. By separating and fixing each blind slat separately, the blind slats are arranged vertically at intervals and openable/closable, and both ends are fitted into the lower bottom of the guide groove in correspondence with the lowermost blind slat to form a seat plate. This seat plate is connected to a winding drum installed at the top of the guide tube through wires, and the sunlight outside the window can be blocked by the blind slats, making indoor cooling more efficient. By rotating a large number of blind slats arranged vertically at intervals and overlapping the V-grooves formed on both the front and rear edges of the blind slats, a wall surface of blind slats is formed on the outside of the window. Therefore, it can be conveniently used as a blind shutter that has both the functions of a blind and a shutter.

(d) Embodiments and operations Embodiments of the present invention will now be explained with reference to the drawings as follows.

In the figure, reference numerals 1 and 1 denote left and right guide tubes provided on the wall surface of the house outside the window frame 2, and a guide groove 3 is provided on the inner wall surface of the guide tubes.

Reference numeral 4 denotes a large number of blind slats having V grooves 5, 5 formed on both front and rear edges, and the left and right ends of the central support shaft 6 of the blind slats are fitted into the guide grooves 3, and the blind slat plates are inserted into the guide grooves 3. A chain 9 is formed by winding the front and rear ends of a receiving piece 7 fixed diagonally across the plane around a drum 8 which is rotated in forward and reverse directions by a motor installed above the guide cylinder 1 in a double winding manner, and having both ends hanging down. (a chain in which a connecting ball and a connecting line are connected in a chain) are individually fixed at predetermined intervals to an extension of the connecting ball and a connecting line, so that they can be opened and closed vertically and spaced apart. Reference numeral 10 designates a seat plate provided below the lowermost blind slat 4, with a rising piece 11 protruding from its upper surface for supporting the lowermost blind slat 4, and receiving portions at both left and right ends. 12
This receiving part is fitted into the guide groove 3, and the lower end of a band-shaped wire 15 to be wound onto a winding drum 14 rotated by a motor is connected to this through an idling roller 13 provided at the upper part of the guide tube 1. It has been done.

16 is a rotating shaft of the drum 8 and idle roller 13 installed in the shutter case 17, 18 is a rotating shaft of the winding drum 14 installed in the shutter case 17, and 19 is a rotating shaft of the shutter case 17.
Sprockets 22, 22 of the reducer 21 and the rotating shafts 16, 18 are connected to both sides of the motor via clutches 20, 20.
Sprockets 23, 23 provided on the chain 2
4, 24 are wound around the rotary shafts 16, 18.
It rotates.

Since the present invention is configured as described above, now,
As shown in FIG. 4 of the drawings, in a state where a large number of blind slats 4 are supported by a seat plate 10 and are stored on top of each other on the outside of the window frame 2, a switch (not shown) installed in the room is installed. motor 1 by the operation of
Winding drum 1 which starts 9 and is connected to this
4 is rotated to let out the strip wire 15, as shown in FIG. When the winding drum 14 reaches a receiving plate 25 protruding from the outside of the lower edge of the frame 2, the winding drum 14 stops and the blind slats 4 are disposed on the outside of the window frame 2 at a predetermined distance from each other. Therefore, it can be used as a blind. In this state, if the drum 8 is rotated by operating the switch, the receiving piece 7 is pulled by the chain 9 and rotates, and together with this, a large number of blind slats 4 are rotated. is turned 90 degrees, and the V grooves 5 formed on both the front and rear edges overlap each other, forming a wall surface of the blind slats 4 on the outside of the window frame 2, as shown in Figures 1 and 2 of the drawings. It can be used as a shutter for rain protection and crime prevention.

As shown in FIG. 3 of the drawings, with the blind slats 4 open and arranged vertically at predetermined intervals, the winding drum 14 is rotated by the operation of the motor to roll the strip wire 15. When it is rolled up, the seat plate 10 rises and a large number of blind slats 4
are supported by this seat plate and are stacked on top of each other as shown in drawing No. 4.
As shown in the figure, it is stored above the outside of the window frame 2.

(E) Effects of the Invention As described above, the blind shutter according to the present invention can block sunlight by using a large number of blind slats arranged at intervals and openable and closable on the outside of the window frame. Since it is a type of shutter, it can efficiently cool the room, and since it has both the function of a blind and a shutter, it eliminates the need for shutters that were conventionally installed on the window frame. Since the structure is simplified, it is easy to open and close the window, and it can also be used for rain protection and crime prevention, and it can also be easily used as a blind, making a great contribution to the industry as a shutter that can also be used as a blind. It is possible.
