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. For example, it is made of metal, particularly aluminum, provided with the partition body 1 and a pair of guide rails 6 for opening and closing the telescopic partition body 1.
[0006]
In this example, the expansion / contraction partition 1 can be expanded and contracted in the lateral direction (width direction) by disposing the expansion / contraction link mechanisms 3 on the top and bottom of a pair of longitudinal bars 2 in the longitudinal direction. The mechanism 3 is constructed in such a manner that a link is laid in an X shape so as to extend between the alternate vertical bars 2 installed alternately from the end portion, and one of the alternate alternate bars 2 in the longitudinal direction is installed. In this example, the fixed shaft 4 is located at the upper end side in the upper and lower telescopic link mechanisms 3 and the lower end side in the lower telescopic link mechanism 3 and the other upper and lower inward in the longitudinal direction. In the upper telescopic link mechanism 3, a movable shaft 5 is arranged on the lower side of the fixed shaft 4 and in the lower telescopic link mechanism 3 on the upper side of the fixed shaft 4. Intercourse with the other pier 2 The fixed shaft 4 is arranged at the fixed position, the fixed shaft 4 is fixed at a fixed position on the crosspiece 2, and the movable shaft 5 is fixed so as to be slidable in the vertical direction of the crosspiece longitudinal direction. At this time, the X-shaped link is fixed as described above. By making each of the shaft 4 and the movable shaft 5 pivotable, the telescopic partition body 1 can be telescopically opened and closed and the telescopic link mechanism 3 can be telescopically retracted, so that the telescopic partition body 1 can be telescopically opened and closed in the telescopic direction. It is supposed to be done at the same time.
[0007]
The guide rails 6 are a pair of rectangular hollow tops and bottoms arranged horizontally in parallel with the upper and lower end indoors, that is, the rear window side of the longitudinal end of the crosspiece 2 in the telescopic partition 1 in this example. In this example, the telescopic partition 1 is moved in the longitudinal direction of the guide rail 6 by hooking and engaging the L-shaped slider 7 projecting inwardly at both ends in the longitudinal direction of each crosspiece 2 to the guide rail 6. Thus, it is assumed that it can be expanded and closed in the horizontal lateral direction (width direction).
[0008]
At this time, the telescopic partitioning body 1 restrains the telescopic link mechanism 3 by making the pair of crosspieces 2 immovable in the longitudinal direction of the guide rail 6 in the telescopic direction, and opens the sash door B at least one of them. In this example, the pair of crosspiece fixing means is provided as an intermediate crosspiece fixing means that is disposed in front of the opening formed by the above and is configured as an intermediate crosspiece fixing means that can be freely released from the indoor side. The fixing means that cannot be released with respect to one end beam 2 in the expansion / contraction direction of the expansion / contraction partition 1 and the intermediate beam 2 in the middle of the expansion / contraction direction of the expansion / contraction partition 1 are released from the indoor side. It is based on a free intermediate cross fixing means.

That is, in this example, the unreleasable fixing means fixes one end bar, that is, the end vertical bar 2 positioned at one end of the telescopic partition 1 to the pair of guide rails 6. In this example, the 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, that is, for example, a fixing bracket 10 made of an L-shaped angle member is used. Are fixed to the end vertical beam 2 and the guide rail 6 with screws, rivets, etc., respectively, thereby fixing one end of the expansion / contraction partition 1 in the expansion / contraction direction to the guide rail 6 and moving the end at the one end It is assumed that it is prevented and the cancellation is impossible.
[0010]
On the other hand, the intermediate crosspiece fixing means is formed by a receiving metal fitting 11 installed at the intermediate position in the longitudinal direction of the lower guide rail 6 of the pair and a locking metal fitting 16 installed on the crosspiece 2 of the telescopic partition 1. At this time, the locking metal fitting 16 is attached to the indoor side of a predetermined vertical beam 2 of the telescopic partition 1 corresponding to the position of the metal fitting 11, and the longitudinal direction of the beam is guided by the slide case 17. A slide member 23 slidable into and out of engagement with the bracket, and a lever handle that is pivotably coupled to the front end of the non-bracket side of the slide member 23 toward the indoor side and slides the slide member 23 in the detachment direction. 26 and the slide case 17 and the slide member 23 or the lever handle 26 and provided with a rotation link 27 for fixing the lever handle 26 to the slide case 17. There is as of.
[0011]
At this time, the receiving bracket 11 has an extension fixing piece on both the left and right sides of the lower guide rail 6 in the longitudinal direction of the lower side of the guide rail 6 and installed on the indoor side thereof. The sliding base of the locking bracket 16 is formed as a metal having a base and a rectangular protrusion that defines an engaging / disengaging receiving hole protruding from the base toward the indoor side. The case 17 has a base 18 having an overhanging fixing piece 19 on both sides facing the longitudinal direction of the longitudinal beam 2 attached thereto, and a pair of protruding connecting pieces 20 on both sides in the width direction from the base 18. And a cylindrical slide guide 21 extending in the vertical direction and projecting toward the indoor side, and the slide member 23 is slidable by the guide of the cylindrical slide guide 21 of the slide case 17. As shown in the figure, a hollow or solid cross-section rectangular shape that fits and slides in accordance with the shape of the cylindrical slide guide 21 is provided, and a connecting piece portion 24 that protrudes so as to be thinned is provided at the upper end thereof, and slides up and down. Accordingly, the lever handle 26 is made of the same metal that protrudes and sinks into the receiving hole 15 of the receiving bracket 11 and can be freely engaged with and disengaged from the receiving bracket 11. The lever handle 26 overlaps the connecting piece portion 24 of the slide member 23. Similarly, it is made of a metal that is pivotally attached to the front end of the non-receptor side of the slide member 23 so as to be pivotable toward the indoor side, and has a turning radius larger than the interval between the sash doors. The rotating link 27 is made of a metal plate that intersects the lateral intermediate positions of both sides of the cylindrical slide guide 21 of the slide case 17 and the lever handle. Likewise, the lever handle 26 and the slide member 23 are fixedly held on the slide case 17 by pivotally fixing both ends in the longitudinal direction between the intermediate positions on both sides of the rod 26 so as to be rotatable. 26, and a pair of link plates on both sides for engaging and disengaging the slide member 23 with respect to the metal fitting 11.

Therefore, the lever handle 26 and the slide member 23 are fixed to the slide case 17 by the rotation link 27 and are held and prevented from being detached or dropped, and the lever handle 26 is rotated and the slide member 23 is thereby moved. The lever handle 26 can be engaged with and disengaged from the bracket 11, and the lever handle 26 is rotated by the rotation link 27 so that the shaft support portion on the slide case 17 side is the center position and the length between the shaft supports is a radius. And the rotation is performed smoothly and reliably. That is, the lever handle 26 stands on the slide case 17 and is arranged in series with the slide member 23, so that the slide member 23 is lowered and engaged with the bracket 11, and the lever handle 26 is rotated downward. By moving and moving the slide member 23 side tip upward, the slide member 23 is lifted so that the slide member 23 is removed from the receiving bracket 11 to be unlocked, and the telescopic link mechanism 3 of the telescopic partition 1 is disengaged. The restraint is released so that it can be opened and closed, and the lever handle 26 is turned upward to restrain the telescopic link mechanism 3 by the reverse operation to the locked state. It is intended to ensure sex. At this time, since the lever handle 26 has a turning radius larger than the interval between the sash door B and the sash door B, the lever handle 26 is rotated when the sash door B is closed. Therefore, the locked state cannot be changed from the locked state to the unlocked state by being obstructed by the sash door B. Therefore, as the crescent locking of the sash door B, for example, between the sliding doors, the crime prevention as the stretchable lattice A On the other hand, in an emergency, the escaper unlocks the crescent from the indoor side, or the rescuer rotates the lever handle 26 by breaking the sash door B from the outdoor side. In the locked state, the telescopic partition 1 is opened by guiding the guide rail 6 and an escape opening for emergency escape from the indoor side to the outdoor side is formed before the opening of the sash door B, and escape from the window is avoided. It is possible to enable the.
