Description

[0001] Blind apparatus [

The present invention relates to a blind apparatus which is automatically operated by a motor and which opens and closes a blind, and more particularly, to a blind apparatus which is capable of being easily folded or unfolded while a plurality of blinds are disposed separately from each other, To a blind device capable of shielding a large door or a window.

In general, blinds are installed on windows to prevent light from entering the room through the windows or to prevent the interior space from being exposed to the outside.

Most of these blinds are made of cloth, and in other cases, thin and hard materials are used.

Therefore, most of these blinds have a structure in which the user unfolds or folds them by manual operation, and is installed and operated indoors.

Therefore, conventional blinds generally have a disadvantage in that they can only function as a door, not only as a window but also as a door.

In this state, it is fixed to the upper part of the housing 100 by using the fixing piece 211 of the fixing block 310 so that the blind guide part can be operated in the housing by the driving part.

After the other one is further coupled in the same manner as described above, the support pieces are fixed to be opposed to each other, and the blinds 400 are fixed to the support pieces, So that the motor can be operated.

At this time, a control unit (not shown) is additionally installed on the motor side to control the normal rotation and the rotation amount of the motor.

Hereinafter, an operation state of the present invention will be described with reference to the accompanying drawings.

A blind guide portion is provided in the housing as described above and a driving portion is provided on the housing. In the drawings, portions that are considered unnecessary for describing the configuration for operation of the present invention in more detail and in detail are omitted Respectively.

6, the blind apparatus 10 of the present invention is configured such that the engaging protrusion 243 of the rotating plate 240 is inserted into the engaging groove 265a of the stopper 265 in a state where the rotating plate 240 is initially rotated, The latching pin 231 engaged with the chain 230 is in a state in which the latching protrusion 243 is extended to the latching protrusion 265b so that the rotating plate can no longer be rotated in the forward direction And the fixing arm 334 of the link stand 330 is positioned to be inclined to one side as the rotation plate 240 is rotated.

Further, as the fixing arm 333 is inclined, the supporting piece 334 is horizontal, and the blind 400 provided on the supporting piece is also horizontal.

The link rotating plate 340 rotatably coupled to the guide body 310 rotates in the rotating direction of the rotating plate as the rotating plate 240 rotates and the guide pin 312 of the guide body 310 is rotated by the pin guide And is guided along the groove 343.

7, in order to fold the blind 400 of the present invention in this state, the rotation plate 240 is not engaged by the stopper 265, so that the rotation plate 240 is no longer rotated, The first guide base 321 and the second guide base 316 connected to the lower end of the chain 230 are moved downward by the sprocket 220 in the normal rotation The first arm 331 and the second arm 332 are folded by the fastening holes 331a and 332a and the blinds 400 are folded by the fastening holes 331a and 332a, To the upper direction.

That is, as the chain 230 moves, the guide body 310 connected to the chain 230 rises and folds the link band, and a plurality of blinds 400 connected to the link band are folded upward to align them .

The space (not shown) between the housings is opened by the blinds arranged in the upper folded state as described above, thereby functioning as a door of the entrance and opening the window.

Next, a description will be made of an operation of expanding and overlapping the blinds. In this case, the sprockets in FIG. 7 are rotated in the reverse direction (clockwise direction) to lower the folded blinds so as to have a predetermined interval.

8, when the blinds 400 are completely opened, the engagement pins 231 are engaged with the sprocket 220 in a state where the engagement grooves 244 of the sprocket 220 and the rotation plate 240 are aligned with each other, When the sprocket is rotated (in the direction of the arrow in the figure), the sprocket and the rotary plate 240 are engaged with each other by the engagement pin 231 so as to rotate and are engaged with the engagement protrusion 243 The stopper 265b of the stopper 265 in the unlocked state is pushed outward to push out the engagement of the stopper primarily.

9, the sprocket 230 coupled to the engaging pin 231 and the rotating plate 240 are simultaneously rotated and the pressing surface 245 of the rotating plate 240 is rotated Pushes the bottom surface 265c and pushes the stopper outward to completely release the stopper 265 from the rotary plate and one of the link bars 330 connected to both ends of the fixed plate 250 is raised and the other is raised The fixing arm 333 is rotated so that the blind 400 coupled to the supporting piece 334 of the fixing arm 333 is vertically aligned so that the ends of the adjacent blinds overlap each other do.

In addition, the stopper 265 stops to rotate when the rotating plate is rotated in the forward and reverse directions while being constantly pressed in the axial direction by the first elastic member, and the second elastic member connecting the lower link rotating plate and the guide body The link rotating plate is retracted by the elasticity while maintaining the tensioned state according to the overlapping operation of the blinds.

At this time, the rotation of the sprocket 220 is no longer rotated due to the overlap of the blinds, but it is also possible to control the rotation amount of the motor according to the control signal of the control unit.

Further, the separate operation of the rotary plate and the sprocket is enabled by the hollow shaft and the hexagonal shaft formed in the sprocket. The hexagon shaft rotates the sprocket. The hollow shaft is coupled to the rotating plate. When the rotation of the rotating plate is not restricted by the stopper, the hollow shaft rotates at the same time. However, when the stopper restricts the hollow shaft, the hollow shaft slides between the rotating plate and idles. So that it is possible to operate in such a manner that only the rotation is performed.

In this manner, the functions of superimposing, unfolding, folding, and the like of the blind can be divided and performed by the operation in the forward and reverse rotation (forward rotation is opposite to the time and reverse rotation is in the clockwise direction) It is possible to perform opening and closing functions of a role or a window. At this time, it is preferable to use blinds having a constant thickness and rigidity.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. There is no doubt that it is within.
