A plurality of mutually independent shutter panels are interposed such that they can be raised and lowered, and lower rollers that are engaged with the first rail are rotatably mounted on both sides of each shutter panel via a support shaft, The middle part of a rotary piece is rotatably supported on both upper sides of each shutter panel, and one end of this rotary piece is attached to the second
An upper roller engaged with the rail is rotatably mounted on a shaft, and a cam is formed at the other end to push up the support shaft of the lower roller and separate the shutter panels from each other. It is something.

[Effect]

The present invention adopts the above-mentioned method, so that when the lowest shutter panel that has been pulled up last is lowered along the guide rail, each of the shutter panels is fitted into each other in the vertical direction in the width direction. They pile up in the opposite direction, blocking the frontage.

In addition, when opening the frontage, when each shutter panel is pulled up, each shutter panel passes through its upper roller and lower roller to the first and second shutter panels.

Next, one end of the cable 43 is locked to the bottom of both ends of the lowermost shutter panel 17, and the other end of the cable 43 on both sides is attached to the brackets 11 on both sides of the storage case 10. It is latched to the winding drum 14 via a guide roller 44 mounted on an axis.

Next, the operation of the above structure will be explained.

First, when closing the frontage A, when the lowest shutter panel 17 that was last pulled up and stored in the storage case 10 is pulled down, it is wound around the winding drums 14 on both sides by the balance spring 15. The rope 43 is sequentially wound back, and each shutter panel 17 is sequentially lowered from the lowest shutter panel 17 along the guide rail 1. At this time, each shutter panel 17 is moved by its upper roller. 35 is transferred from the upper horizontal rail 8 to the vertical rail 7, and the lower roller 41 is transferred from the lower horizontal rail 9 to the confluence section 6 and moved laterally, and the shutter panel is moved along the vertical rail 7. 17 is lowered, its lower roller 41 engages with the first rail 3 and is lowered along the first rail 3, and its upper roller 35 passes through the inclined rail 5 to the first rail 4. The shutter panels 17 are engaged with each other and lowered along the first rail 4, and in this way, each shutter panel 17 is lowered in sequence, and the shutter panels 17 are engaged with each other and are lowered in the width direction. Stacked vertically. That is, the engagement protrusion 29 of the lower horizontal frame 19 of the upper shutter panel 17 is engaged on the engagement step 25 of the upper horizontal frame 18 of the lower shutter panel 17, and also on the engagement surface 26 thereof. The protrusions 31 engage with each other, and the upper horizontal frame 18 and lower horizontal frame 19 of the upper and lower shutter panels 17 fit together and are stacked up, and in this way, the mutually independent shutter panels 17 As the shutter panels 17 are stacked one after another in this direction, the shutter panels 17 are securely fitted and locked to each other, thereby reliably closing the frontage A.

Next, when opening the frontage A closed by each shutter panel 17, when the lowermost shutter panel 17 is pulled up, the balance spring 15 causes the cables 43 on both sides to be connected to the respective winding drums 14. each shutter panel 17 is wound around its upper roller 35 and lower roller 41.
via the respective first and second rails 3, 4
It is raised along the The uppermost shutter panel 17 is then pushed upward from the frontage A, and the upper roller 35 of the second shutter panel 17 from the top engages with the inclined rail 5 from the second rail 4. While being raised along the inclined rail 5, the rotating piece 33 having the upper roller 35 is gradually rotated clockwise about the support shaft 34. As the upper roller 35 of the rotating piece 33 approaches the merging part 6 with the first rail 3, the first pushing part 38 of the cam 37 of the rotating piece 33
is engaged with a guide roller 42 of a support shaft 40 that supports the lower roller 41 of the uppermost shutter panel 17, and the support shaft 40 is rotated through this guide roller 42.
is gradually pushed up, and the upper roller 35 of the rotating piece 33 is moved into and engaged with the merging part 6, and the rotating piece 33
When the cam 37 is rotated approximately vertically, the second pushing part 39 of the cam 37, which is continuous with the first pushing part 38, moves to the support shaft via the guide roller 42 instead of the first pushing part 38. Push 40 further. As a result, due to the operation of the cam 37 of the rotating piece 33, the uppermost shutter panel 17, which has been raised while being fitted onto the second shutter panel 17 from the top, is moved over the second shutter panel 17. It is pushed up from and separated from this.

Further, when the second shutter panel 17 is further raised, the rotating piece 33 thereof is raised while remaining substantially vertical, so that the second pushing portion 39 of the cam 37
is gradually removed from the guide roller 42 while moving the support shaft 40 in the lateral direction via the guide roller 42, and the first pushing section 38 replaces the second pushing section 39 and moves further via the guide roller 42. Support shaft 40
is pushed in the lateral direction, and the lower roller 41 mounted on the support shaft 40 is engaged with the lower horizontal rail 9. At this time, the upper roller 35 in the uppermost shutter panel 17 faces from the vertical rail 7 to the upper horizontal rail 8.

When the second shutter panel 17 is pulled up in the same manner, the second shutter panel 17 moves the uppermost shutter panel 17 onto the upper and lower horizontal rails via its upper roller 35 and lower roller 41. Push in along lines 8 and 9. In this way, each shutter panel 17 that is pulled up in sequence is converted from vertical movement to horizontal movement in a mutually separated and independent state at the upper part of frontage A by the operation of the cam 37 of each rotating piece 33. be done. As a result, the frontage A is opened, and each shutter panel 17 is sequentially fed into the storage case 10 parallel to the wall surface B and toward the front side thereof, and is securely stored in an overlapping state. be done.

Next, the structure of the upper horizontal frame 18 and the lower horizontal frame 19 of each shutter panel 17 that fit into each other is not limited to that shown in FIG. As shown, an engagement recess a and an engagement protrusion b are formed in the upper horizontal frame 18 and the lower horizontal frame 19 so that they can be fitted and separated from the vertical direction, and when the frontage A is closed, the engagement recess a and the engagement protrusion b are formed. The recess a and the engaging protrusion b may be fitted into each other so that they can engage and lock with each other.

[Effects of the invention] According to the invention, by forming a plurality of shutter panels independently from each other, the unit width of the shutter panel can be formed to be large in a desired form, and the appearance of the shutter panel can be increased. It is possible to increase the quality of the parts, and there is no need for processing or assembly, which is required for interconnecting them. In addition, since the multiple shutter panels are fitted vertically when they are closed, the multiple shutter panels can be connected and locked together without interruption, and the dustproof performance can be improved. . In addition, by operating the cam of the rotating piece provided on each shutter panel, it is possible to reliably separate the shutter panels from each other, and the upper shutter panel is separated and independent from the lower shutter panel. can be reliably moved horizontally and engaged with the horizontal rail of the guide rail. In addition, a shutter panel that has been moved onto a horizontal rail can be successively pushed in by the next shutter panel and stacked side by side, and this is not rolled up, so multiple shutter panels can be stored in a small storage space. can be reliably stored, and the dimensions of the horizontal stile can also be reduced. Furthermore, when the plurality of shutter panels are stored, the vertical movement is converted into horizontal movement, and since this is not rotated, the fitting material is stable.
