And Figure 3 is a plan view of the folding shade unit 10 according to the present invention is shown.

The shade unit 10 according to the present invention includes a center plate 100 , a frame 200 , a membrane member 300 and a reinforcing material 900 .

The center plate 100 is located in the center of the foldable shade unit 10 according to the present invention, and serves as a reference for other components constituting the shade unit 10 . The center plate 100 may be formed in a disk shape, for example.

The plurality of frames 200 serve to support the membrane member 300 to be described below, and each has a long bar shape. Each frame 200 may have one end rotatably coupled with respect to the center plate 100 to fold the membrane member 300 . That is, when the frames 200 are positioned radially with respect to the center plate 100 , the membrane member 300 is unfolded, and the frames 200 are rotated and positioned in contact with each other in one direction of the center plate 100 . The membrane member 300 is folded. The rotation axis of each frame 200 is positioned parallel to the central axis of the center plate 100 .

The membrane member 300 is formed in a membrane shape and serves to form a shade, and is formed while connecting a plurality of frames 200 . The membrane member 300 has a portion that is split along the radial direction in at least one place.

The reinforcement 900 may have one end connected to the center plate 100 and the other end connected between one end and the other end of the frame 200 to firmly support the frame 200 . That is, each frame 200 may be structurally unstable because only one end is coupled to the center plate 100 compared to the long bar shape, but by reinforcing each frame 200 using the reinforcing material 900 , the frame (200) can be structurally stable.

Since the foldable shade unit 10 of the present invention is structurally stable, it is less likely to be damaged by wind, etc., so it is possible to facilitate the management of the shade shade.

And since the axis of rotation of each frame 200 is formed parallel to the central axis of the center plate 100, there is no fear of interfering with pedestrians located under the shade curtain when the frame 200 rotates while the shade curtain is folded.

More specifically, the reinforcing material 900 may be a tensile reinforcing material 910 pulling the frame 200 upward from the upper portion of the frame 200 . 4 is an explanatory view of the tensile reinforcement 910 is shown.

The tensile reinforcing material 910 is made of, for example, wire and connects the middle portion in the longitudinal direction of the frame 200 and the center plate 100 in a tensioned state to prevent the frame 200 from sagging downward.

The tensile reinforcing material 910 may be disposed to be inclined upward toward one end of the frame 200 so that the tensile reinforcing material 910 may pull the frame 200 upward.

The tensile reinforcement 910 made of wire is hardly conspicuous, and since the members supporting the membrane member 300 other than the frame 200 in the shade unit 10 are inconspicuous, the shade unit 10 gives a simple feeling. can have Accordingly, the appearance of the shade unit 10 is excellent.

One end of the tensile reinforcement 910 may be formed to be movable along the circumference of the center plate 100 .

For example, a spherical rolling member 911 is formed at one end of the tensile reinforcing material 910, and a groove ( 120 is formed, and by moving the rolling member 911 along the groove 120 , it is possible for one end of the steel reinforcement to move along the circumference of the center plate 100 .

The length of the tensile reinforcing material 910 is such that the tensile reinforcing material 910 is tensioned in the fully unfolded state of the shade unit 10 so that the unfolding process of the frame 200 is not disturbed by the tensile force of the tensile reinforcing material 910 . do.

As shown in FIG. 5 , the reinforcement 900 may be a compression reinforcement 920 supporting the frame 200 under the frame 200 .

The compression reinforcing material 920 may be made of, for example, steel to support the middle portion in the longitudinal direction of the frame 200 to prevent the frame 200 from sagging downward.

The compression reinforcing material 920 may be disposed to be inclined downwardly toward one end of the frame 200 so that the compression reinforcing material 920 can firmly support the frame 200 . To this end, one end of the compression reinforcing material 920 may be connected to the center plate 100 through the connecting member L positioned below the center plate 100 .

The compression reinforcement 920 may be rotatably formed together with the frame 200 .

Accordingly, when the frame 200 rotates with respect to the center plate 100 for folding of the shade unit 10 , the compression reinforcing material 920 may not interfere with the rotation of the frame 200 .

As with the frame 200 , the compression reinforcing material 920 may rotate together with the frame 200 by being rotatably formed at one end with respect to the center plate 100 .

Unlike this, a gear is formed on the rotation shaft of the driving motor 410 and the rotation shaft of the frame 200 receiving the rotation of the driving motor 410 and meshed with each other so that the rotational force of the driving motor 410 is transmitted to the frame 200 It is also possible

The foldable shade unit 10 according to the present invention may further include a rotating plate 500 .

The rotating plate 500 is rotatably formed with respect to the central plate 100 with respect to the central axis of the central plate 100 . And the frames 200 may be coupled to the center plate 100 through the rotating plate 500 . Accordingly, the frames 200 can be rotated with respect to each of the rotation shaft portions (A) and each can rotate with respect to the center plate 100 , and with respect to the center plate 100 at once by the rotation of the rotation plate 500 . It can also rotate.

Even when the frame 200 is coupled to the central plate 100 through the rotating plate 500 , one end of each frame 200 is rotatable with respect to the central plate 100 , so that one end of each frame 200 is connected to the rotating plate 500 . ) is rotatably coupled to

The rotating plate 500 is, for example, located under the central plate 100 , and the frames 200 may be coupled to the rotating plate 500 between the central plate 100 and the rotating plate 500 .

When the folding shade unit 10 according to the present invention includes the rotating plate 500 , the rotation transmitting member 420 transmits the rotation of the driving motor 410 to one frame 200 among the plurality of frames 200 . transmit The frame 200 receiving the rotation of the driving motor 410 is referred to as a driving frame 210 .

Even if the rotation of the driving motor 410 is transmitted only to the driving frame 210 , the frames 200 are all connected to the center plate 100 by the rotation of the rotating shaft portion A of the driving frame 210 and the rotation of the rotating plate 500 . It can be rotated about to be fully folded or unfolded.

When the foldable shade unit 10 according to the present invention includes the rotating plate 500 , the guide groove 110 may be formed in the center plate 100 .

The guide groove 110 is formed along a path through which the rotation shaft portion A of the driving frame 210 passes when the rotation plate 500 rotates, and may guide the movement of the rotation shaft portion A of the driving frame 210 . . In addition, it is possible to prevent the connection between the rotation transmission member 420 and the driving frame 210 from interfering with the center plate 100 when the rotation plate 500 is rotated.

Hereinafter, the operation process of the foldable shade unit 10 according to the present invention will be described in detail. 8 to 10 show the folding process of the foldable shade unit 10 according to the present invention in order.

First, as shown in (a) of FIG. 8 , the driving frame 210 is rotated by the driving unit 400 based on the rotating shaft portion A. As shown in FIG. When the driving frame 210 rotates and presses the frames 200 positioned in the rotational direction in sequence, as shown in FIG. 8(b), about half of the frames 200 are positioned side by side. do.

After the frames 200 are folded to some extent, the rotational force of the driving unit 400 makes it difficult to rotate the driving frame 210 , and is transmitted to the rotating plate 500 through the driving frame 210 . Accordingly, as shown in FIGS. 9 and 10 , as the rotating plate 500 rotates, the frames 200 rotate together, so that the frames 200 can be completely folded.

When the foldable shade unit 10 according to the present invention is unfolded, the driving unit 400 rotates the driving frame 210 in the opposite direction. After the frames 200 are unfolded about half by the rotation of the driving frame 210, the rotational force of the driving unit 400 makes it difficult to rotate the driving frame 210, so that the rotating plate 500 rotates so that the frames 200 are fully unfolded. do.

The foldable shade unit 10 according to the present invention may include a first alignment stopper 610 .

When the rotation direction when the driving frame 210 is unfolded is referred to as one direction, the frame 200 positioned adjacent to the driving frame 210 in one direction is referred to as an alignment frame 220 .

The first alignment stopper 610 serves to prevent the alignment frame 220 from moving in one direction, and in a state in which the frames 200 are fully unfolded, contact the alignment frame 220 at one side of the alignment frame 220 . positioned to do

Accordingly, after the frames 200 are fully unfolded, the rotating plate 500 may not rotate.

The alignment frame 220 may be fixed to the lower surface of the center plate 100 to serve to prevent the rotation plate 500 from rotating any more.

The foldable shade unit 10 according to the present invention may further include a second alignment stopper 620 .

The second alignment stopper 620 is disposed to be spaced apart from the first alignment stopper 610 in the other direction, and may be fixed to the lower surface of the center plate 100 like the first alignment stopper 610 .

The second alignment stopper 620 causes the alignment frame 220 to rotate in one direction at a predetermined position, so that the alignment frame 220 is moved to a predetermined position by the rotation of the rotating plate 500 in the process of folding the frames 200. When the alignment frame 220 is rotated, the frames 200 are all positioned side by side so that they can be completely folded.

That is, when the rotation plate 500 rotates to a position where the alignment frame 220 is in contact with the second alignment stopper 620 as shown in FIG. 9(b), the alignment frame 220 is a second alignment stopper ( As shown in (a) of FIG. 10 by interference with the 620, the rotation plate 500 rotates in one direction by further rotation. When the alignment frame 220 is rotated and the frames 200 positioned in the rotation direction of the alignment frame 220 are pressed one after the other, eventually the driving frame 210 as shown in FIG. The frames 200 positioned side by side by the frame 200 and the frames 200 positioned side by side by the alignment frame 220 are all positioned side by side.

The foldable shade unit 10 according to the present invention may include two second alignment stoppers 620 .

After one second alignment stopper 620 aligns adjacent frames 200 in the rotational direction of the alignment frame 220 to some extent, the remaining second alignment stopper 620 is the alignment frame 220 is the driving frame. The process of folding the frames 200 is completed by making them almost completely parallel to the 210 .

The second alignment stopper 620 is formed to interfere with only the alignment frame 220 among the plurality of frames 200 .

Accordingly, the frame 200 other than the alignment frame 220 may interfere with the rotation of the rotation plate 500 by interfering with the second alignment stopper 620 .

For example, the alignment frame 220 is formed to protrude more in the direction of the center plate 100 than the other frames 200, and the second alignment stopper 620 formed on the lower surface of the center plate 100 is the alignment frame ( By coming into contact with the protruding portion of 220 , it may be formed so as to interfere only with the alignment frame 220 .

Similarly, the first alignment stopper 610 is formed to interfere with only the alignment frame 220 among the plurality of frames 200 .

In the alignment frame 220, the connection portion with the rotation shaft portion (A) may be formed in a 'L' shape.

The alignment frame 220 having this shape may be more precisely aligned while being in contact with the second alignment stopper 620 from two sides.

The foldable shade unit 10 according to the present invention may further include a fixed frame 700 .

The fixed frame 700 is fixed to the rotating plate 500 on the opposite side of the driving frame 210 and does not rotate with respect to the rotating plate 500 .

In this case, after the driving frame 210 rotates at a certain angle and some frames 200 including the driving frame 210 are positioned in parallel with the fixed frame 700 as shown in FIG. 8(b), The angle of the driving frame 210 with respect to the rotating plate 500 does not change any more, and the rotational force of the driving unit 400 may reliably rotate the rotating plate 500 .

Accordingly, it is possible to prevent the driving frame 210 from being rotated with respect to the rotating plate 500 more than necessary to prevent the frames 200 from being difficult to align in the second half of the folding process of the frames 200 .
