DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a stretchable surface grid, and the stretchable surface grid A is a stretchable structure formed by connecting a plurality of crosspieces 2 by a stretchable link mechanism 3 so as to be simultaneously stretchable. It is made of aluminum provided with a partition 1 and a pair of guide rails 6 for extending and closing the telescopic partition 1.
[0006]
In this example, the telescopic partitioning body 1 is designed to be telescopic by disposing the telescopic link mechanisms 3 on a pair of upper and lower sides of the longitudinal bars 2 in the longitudinal direction. A link is laid in an X-shape so as to extend between alternate vertical bars 2 that are installed alternately, and the upper and lower sides of the alternate alternate bars 2 are moved upward and downward in the longitudinal direction. The fixed shaft 4 is located at the upper end side of the lower telescopic link mechanism 3, the lower end side of the lower telescopic link mechanism 3, and the lower side of the fixed shaft 4 in the upper telescopic link mechanism 3 with the other upper and lower inward in the longitudinal direction. The movable shaft 5 is disposed on the upper side of the fixed shaft 4 in the lower telescopic link mechanism 3, and the fixed shaft 4 is disposed at the intersection with the alternate beam 2 positioned between the alternate beams 2. The fixed shaft 4 is positioned on these crosspieces 2 The movable shaft 5 is fixed so as to be slidable in the vertical direction in the longitudinal direction of the crosspiece. At this time, the X-shaped link can be rotated on the fixed shaft 4 and the movable shaft 5 respectively to thereby expand and contract the partition. The body 1 can be opened and closed freely and the expansion and contraction link mechanism 3 can be extended and retracted simultaneously.
[0007]
The guide rails 6 are a pair of horizontally-oriented rectangles arranged horizontally and parallel to the upper and lower ends of the telescopic partition 1 at the end in the longitudinal direction, that is, on the back side of the window. By extending and engaging the L-shaped slider 7 projecting to the guide rail 6, the telescopic partition 1 is expanded and closed in the longitudinal direction of the guide rail 6 in the horizontal direction in this example. As a thing.
[0008]
At this time, the telescopic partition body 1 has a pair of cross rail fixing means for restraining the telescopic link mechanism 3 by making the pair of cross bars 2 immovable in the longitudinal direction of the guide rail 6 in the telescopic direction. 6 is installed between the mounting bar 22 laid between 6 and the intermediate bar 2 in the middle of the expansion / contraction direction of the expansion / contraction partition 1, and at least one of them is arranged in front of the opening formed by opening the sash door B. In this example, the pair of crosspiece fixing means is connected to one end crosspiece 2 in the extension / contraction direction of the extendable partition 1. On the other hand, the fixing means that cannot be released and the intermediate beam fixing means that allows the intermediate beam 2 in the middle of the expansion / contraction direction of the expansion / contraction partition 1 to be freely released from the indoor side.
[0009]
That is, in this example, the unreleasable fixing means is based on fixing one end vertical bar 2 positioned at one end of the telescopic partition 1 to the pair of guide rails 6. In this example, the above-mentioned one end vertical beam 2 is fixed to the guide rail 6 at the upper and lower ends at both ends in the longitudinal direction, and a fixing bracket 10 made of an L-shaped angle member is used. Each of the rails 6 is fixed to each of the rails 6 with a rivet or the like, whereby one end of the expansion / contraction partition 1 in the expansion / contraction direction is fixed to the guide rail 6, and the movement is blocked at the one end and disabled. .
[0010]
On the other hand, the intermediate beam fixing means that can be released from the indoor side is paired with the fixing means, so that the middle of the expansion / contraction direction of the expansion partition 1 in front of the opening when the sash door B is opened, this example In this case, the intermediate beam 2 located in the middle of the other end in the direction of expansion opposite to the one end where the fixing means is installed is fixed releasably so that the expansion and contraction can be performed simultaneously. While the expansion / contraction link mechanism 3 of the partition 1 is constrained, the constraining is released by releasing the constraining link mechanism 3 so that the expansion / contraction opening / closing can be performed. The intermediate beam fixing means is formed by a receiving metal fitting provided on the back side of the indoor side below the intermediate beam and a locking metal fitting 24 provided on the mounting beam 22.
[0011]
At this time, the receiving bracket 20 is made of a plane C-shaped piece fitting having a vertical slit 21 opened toward the indoor side, and the locking fitting 24 is connected to the lever handle 26. It is formed by a locking metal fitting 27 that is integrally installed at the tip thereof, and the lever handle 26 of the locking metal fitting 24 is turned to the inner side of the mounting bar 22 and is pivotable to a shaft support member 25 fixed at a lower position thereof. The lever handle 26 is pivotable inwardly, and the locking bracket 27 at the tip thereof is received by the bracket 20 through the through hole 23 that is formed in the mounting bar 22 by raising the lever handle 26. The end bent projecting piece 28 is hooked and locked to the bracket 20 and is pulled out of the slit 21 of the bracket 20 by the turning operation of the lever handle 26. There as by crescent-shaped metal fitting formed in a semicircular shape to release the locking.
