The link is rotatable at a fixed position, and the link is slidable and rotatable on the movable shaft 5, whereby the telescopic partition 1 is made telescopic, especially the above-mentioned telescopic partition, and the telescopic partition 1 is opened and closed. It is performed simultaneously in the direction of expansion and contraction.

[0008] A pair of parallel guide rails 12 is
A pair of guide members 6 provided at or near the longitudinal end of the slidable guide member 6 for slidingly guiding the expandable / contractible partition 1 to open and close the wall.
Also, at this time, one of the pair of guide members 6 is slidable in the longitudinal direction of the bar 2 on the bar 2 and the other guide member 6 is slidable in the longitudinal direction of the bar 2 by placing the other in a fixed position on the bar 2. One of a pair of parallel guide rails 12 for slidingly guiding the position can be adjusted in the crossing direction of the telescopic partition 1.

That is, in the present embodiment, the guide member 6 is slidable on the upper side of the bar 2 arranged in the vertical direction, and is fixed at the lower end on the lower side. Upper guide rail 1
2 is slidable in the vertical direction. At this time, the guide member 6 has a C-shaped guide portion 7 which is fitted on the guide rail 12 on its upper side and which is fitted to the crosspiece and slidably engages with the T-shaped guide portion. The C-shaped guide portion 7 of the guide member 6 is enclosed by an upper guide rail 12. Is fitted to
The T-shaped guide portion 8 is connected to the bar 2 having a substantially C-shaped cross section in this embodiment for the sliding rotation of the movable shaft 5 of the telescopic link mechanism 3. The guide member 6 on the lower side is attached to the guide rail 12 by the guide rail 1 so as to be slidable in two directions.

With this arrangement, the guide rails 12 are arranged on the indoor side of the window, and the stretchable surface grid A is installed on the wall surface so that the expandable partition 1 is arranged on the outside of the window. If you fix this below the window,
The upper guide rail 12 can be adjusted and fixed above it according to the size of the window.

At this time, in the present embodiment, the bar 2 located at one end in the longitudinal direction of the pair of upper and lower guide rails 12 in parallel with the end of the telescopic partition 1 is adjusted in position with respect to the upper guide rails 12. Later, it is fixed by fixing means 13 such as screw fixing. By performing this fixing, the extensible partitioning body 1 is set at the end portion at the hanging position, so that the load can be supported and the extensible partitioning body 1 can be expanded and contracted. The partitioning body 1 has a linearity in the direction of expansion and contraction by the telescopic link mechanism 3 and can prevent swinging such as hanging at the opening / closing end, that is, the free end, and the lower guide rail. 12
Although the L-shaped guide portion 9 of the lower guide member 6 is fitted into the lower support member in the form of a support, the fall of the lower guide rail 12 and the detachment from the lower guide rail 12 due to the load of the telescopic partition 1 are prevented. It becomes possible to stably support and fix the telescopic partition body 1 later and open and close in an emergency.

The fixing of the pair of parallel guide rails 12 to the wall surface is performed by using a pair of brackets 15 for the guide rails 12 as a single or a plurality of members as in the conventional method.

By adjusting the position of the upper guide rail 12 and the position of the bracket 15, the elastic surface grid A can be adjusted in both the vertical and horizontal directions, and can be adapted to the size of the window. .

The locking means 21 prevents the expansion and contraction of the telescopic partition 1 and allows it to be opened and closed by releasing from the indoor side in an emergency. A pair of bars 2 are used for link restraint which prevents the opening and closing of the pair of bars 2 by immobilizing the telescopic link mechanism 3 by making the pair of bars 2 immovable.
The locking means 21 of the present embodiment uses a bar 2 fixed at an end to one end in the longitudinal direction of a pair of parallel guide rails 12 of the telescopic partitioning body 1, and additionally, one of the pair of parallel guide rails 12, especially a book. In the example, a rotatable lever having a spun-shaped engaging portion fixed to an upright frame portion 22 fixed to a lower guide rail 12 via an L-shaped angle so as not to hinder opening and closing of the elastic partitioning body 1 The lever 23 is rotated by rotating the lever handle 23 by using a handle 23 and a metal fitting 24 provided on the bar 2 at a position corresponding to the handle 23 when the telescopic partition 1 is closed. By making the engaging portion detachable from the metal fitting 24, the bar 2 at the above-mentioned one end of the telescopic partition 1 and the bar 2 fixed by the lock metal are paired so that they cannot be moved. The expansion and contraction link mechanism 3 are to be constrained.

At this time, the turning radius of the lever handle 23 is increased by increasing the lever length, and the turning radius is set to intersect with the sash door 25 of the window, and the sash door 25 is closed. When the lever handle 23 is in a locked state in which the lever handle 23 cannot be rotated, the opening and closing of the telescopic partition 1 is disabled, and by opening the sash door 25, the lever handle 23 is rotated with one touch to extend and retract the link. The mechanism 3 is released so that the telescopic partition 1 can be opened and closed, and an escape opening can be formed in front of the sash door 25.
