As shown in FIG. 5A, the bracket 120 except for the bracket 120 at the left end of the pair of brackets 120 includes a roller link strut 121 protruding from one end, And link posts 122 and 123 protruding from the ends.

The roller link pillars 121 are larger in height than the link pillars 122 and 123 protruding from the center and the other end, respectively, at one end thereof, and threaded lines are provided for the respective inner diameters.

As shown in FIG. 5B, the bracket 120 at the left end of the bracket 120 includes a hinge support 124 protruding from one end, a link support 125 protruding from the center and the other end 126).

The height of the hinge strut 124 at one end portion and the height of the link struts 125 and 126 at the center and the other end are the same and screw threads are provided for each inner diameter.

The link 130 is divided into a pair of long links 131 and a pair of short links 132 which are attached to the upper and lower sides of the bracket 120. The long link 131 is connected to the brackets 120 6a, a bracket connecting hole 131a is provided at the center of the long link 131, and both ends of the long link 131 are pierced with bracket connecting holes 131b and 131c as diagonally asymmetrical.

Bracket connecting holes 132a and 132b are formed in both ends of the short link 132, as shown in FIG. 6B.

The brackets 120 except for the brackets 120 at the left and right ends are coupled with the long links 131 and the brackets 120 at the left and right ends are assembled in addition to the short links 132 Nut.

7, the upper driving part 141 includes a first roller 141 and a second roller 142 protruding from one side of the bracket 120, The column connecting hole 141a to be assembled to the link strut 121 is pierced and can be fastened with the engaging member.

Here, the engaging member can be fastened by bolt (B1) or riveting.

In addition, rollers 141b are provided on both sides of the upper driver 141 and roller housings 141c are provided on the lower side.

The rollers 141b provided on both sides are guided and rotated in a roller guide groove 161c provided in the upper guide frame 161 to be described later and the roller housing 141c is disposed on the lower side of the upper guide frame 161 And means for supporting the wobbling of the door 110 when the plurality of doors 110 are assembled to slide to prevent noise.

8, the lower driving part 142 is formed with a column connecting hole 142a formed in a roller link support 121 protruding from the bracket 120 at the center thereof, Respectively.

Here, the engaging member can be fastened with the bolt B2 or riveting.

And a roller 142b on the lower side of the lower driver 142.

The roller 142b reciprocates in a roller guide groove 162c provided in a lower guide frame 162 to be described later.

The hinge roller unit 150 is divided into a hinge housing 151 and a hinge member 152. The hinge housing 151 has a stopper 151a at both ends thereof And a plurality of guide protrusions 151b in the longitudinal direction from the upper side to the lower side.

9 to 10, the hinge member 152 is provided with rollers 152a on both sides and a protrusion 152b which is braked by the stopper 151a is provided on the same line as the roller 152a, And a hinge connection hole 152c is formed at the opposite end of the roller 152a so as to be assembled to the hinge support 124 provided in the left end bracket 120. [

Here, the hinge roller unit 150 is capable of adjusting the sliding movement section L1 of the storage type door 100, and has a means for allowing the movable door 100 to be movable in a variable manner in accordance with the width of the opening.

In other words, when the width of the opening portion is large, the hinge roller portion 150 is moved to the right to move the storage door 100 to the right side. On the contrary, when the width of the opening portion is small, To move to the left and the storage-type door 100 to move to the right by that amount.

The guide frame 160 is divided into upper and lower guide frames 161 and 162 to be fixed to the ceiling and the floor. First, as shown in FIG. 11, The rear frames 161a and 161b are separated from each other by a bolt B3. The bolts B3 can easily be fastened and dismounted so that the inside thereof can be repaired or replaced.

A roller guide groove 161c in which the roller 141b of the upper drive portion 141 is assembled is provided below the front and rear frames 161a and 161b, 161d are provided with a housing guide groove 161e in which the hinge housing 151 of the hinge roller unit 150 is assembled.

The lower side of the roller guide groove 161c provided in the rear frame 161b is semicircular with the same shape as the outer peripheral edge of the roller 141b to be assembled. However, the lower side of the roller guide groove 161c of the front frame 161a It is flat.

This is because the roller 141b can not be assembled if the rear frame 161b has a semicircular shape like the lower side of the rear frame 161b when the front frame 161a is assembled after the roller 141b is assembled.

1 or 10, the hinge housing 151 of the hinge roller unit 150 is assembled to the inside of the channel 162a protruding upwardly from the lower guide frame 162 And a roller guide groove 162c in which a roller 142b of the lower drive portion 142 is received is formed at the center of the lower guide frame 162. [

The bottom surface of the roller 142b accommodated in the roller guide groove 162c is positioned on the upper side at a predetermined height from the bottom surface of the roller guide groove 162c and its outer circumferential edge is in a state of being in close contact with the side surface of the roller guide groove 162c .

The lower side of the roller guide groove 162c is an inclined surface 162d for allowing the rainwater to be concentrated in one direction and the rainwater collected in one direction can be drained to the outside on one side surface of the roller guide groove 162c A plurality of drain holes 162e are provided at regular intervals.

A door 122 is provided at the end of the door 110 located at the right end of the plurality of doors 110 so that the door 100 can be opened and closed by a plurality of doors interlocked with each other, 113 are coupled to each other.

The operation of the retractable door provided at the opening of the building of the present invention having the above-described structure is as follows.

First, as shown in FIGS. 12A to 12C, when a plurality of doors 110 are folded and stored in the curtain 180, when the handle 111 is artificially pulled at the right end, The plurality of brackets 120 are horizontally slid while the upper and lower driving parts 141 and 142 in the frames 161 and 162 are driven and the plurality of long links 131 are connected to the center bracket connecting hole 131a, And the short link 132 is also rotated counterclockwise by the progress of sliding of the brackets 120 on both sides and horizontally unfolded so that the storage type door 100 is opened.

The operation of the upper and lower drive units 141 and 142 in the upper and lower guide frames 161 and 162 is performed by the roller 141b of the upper drive unit 141, The roller housing 141c is brought into close contact with the lower ends of the front and rear frames 161a and 161b to be rotated on the upper side of the plurality of doors 110 As shown in FIG.

  The outer periphery of the roller 142b of the lower driver 142 is closely contacted with the roller guide groove 162c of the lower guide frame 162 so that the underside of the plurality of doors 110 moves smoothly.

9 to 10, the hinge roller unit 150 is rotated by the channel 161d of the rear frame 161b and the channel 161d of the lower guide frame 162 The roller 152a moves to the right by the movement of the bracket 120 at the left end coupled with the hinge member 152 and the guide protrusion 151b, And the protrusion 152b at the right end is braked by the stopper 151a of the hinge housing 151. [

On the other hand, among the plurality of doors of the storage type door 100, the reading bar 113 coupled to the door 110 at the right end of the door 100 slides and moves horizontally when the handle 112 is pulled Other operations are the same as the above-mentioned contents and are omitted.
