BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail with reference to examples shown in the drawings. A is an aluminum emergency escapeable stretched grid formed of, for example, an extruded aluminum material. The elastic surface lattice A is provided with an elastic surface lattice body 1, a pair of parallel guide rails 13, and a lock device 14. In this example, the elastic surface lattice body 1 It is provided with a detachable anti-flap member 10.

The elastic surface lattice main body 1 is configured such that a large number of oblique bars 2 that intersect in a lattice shape are elastically connected to form an elastic lattice body, and that a pair of parallel end bars 3 are disposed at both ends in the elastic direction. In this example, the elastic surface lattice body 1 is
Using a large number of straight cross bars 2 having a C-shaped cross section, these cross bars 2 are arranged in an intersecting manner in the above-mentioned lattice shape, and are fixed rotatably from a fixed shaft 4 at a crossing position at the center of the elastic surface lattice main body 1. At the intersection of the ends, the movable shaft 5
By fixing it so that it can slide freely in the longitudinal direction,
In this example, it is assumed that it can be expanded and contracted in the left and right lateral directions.
At both ends, in this example, at the left and right ends, a pair of parallel end bars 3 having the same C-shaped cross section are arranged as vertical bars, and at this time, the end bars 3 prevent the expansion and contraction of the expandable lattice body. Fixed at the center crossing position or fixed or movable shaft 4 or 5 at the other crossing position by the movable shaft 5 so as to be rotatable or slidable, respectively, and integrally fixed to the telescopic lattice body. It has been done.

A pair of parallel guide rails 13 fixes one end bar 3 of the pair of parallel members to one end in the longitudinal direction, and a guide member 7 provided with the other end bar 3 on the end bar 3.
In the present example, a guide rail is provided for guiding the expansion / contraction surface grid 1 so that the main body 1 can be freely opened and closed by sliding and guiding the expansion / contraction surface lattice 1 via a bracket 19. 13 is a pair of upper and lower parallel bars made of bar material of a square pipe having a C-shaped cross section or a hollow rectangular or rectangular cross section. At one intersection, the one end bar 3 is fixed to a fixed position by a fixing bracket 6 such as a screw or a rivet.

In the present example, the other end bar 3, which is also a vertical bar, uses a guide member 7 made of a synthetic resin integrally molded piece member having a bar fixing portion 8 and a guide portion 9. The guide member 9 is installed so as to protrude toward the guide rail 13 at each of the intersections with the pair of vertically parallel guide rails 13 with both ends in the longitudinal direction of the end bar 3 at this time. 7 is provided with a flat plate-shaped fixing part 8 and a guide part 9 projecting from the fixing part 8 in an L shape.
The beam fixing portion 8 is screwed in contact with the side surface of the end bar 3 and the L-shaped guide 9 is directed downward at the upper end of the end bar 3 and L-shaped at the lower end. The guide portions 9 are arranged upward, and the guide rails 13 are engaged with the guide rails 13 from the outside in a hooking or wrapping manner to guide the guide members 7 in a sliding manner. Of the pair of guide rails 13 vertically movable in the longitudinal direction of the pair of guide rails 13 so as to be movable, so that the end bar 3 can be opened and closed. The telescopic lattice body is expanded and contracted between the fixed end bar 3 and the telescopic surface lattice body 1 so that it can be opened and closed.

At this time, since the stretchable lattice body 1 made of the stretchable lattice body can exhibit the straightness of expansion and contraction without swinging up and down, the guide member 7 can be provided.
In general, it suffices to engage the guide rail 13 while suppressing swinging in the front-rear direction, and to open and close along the guide rail 13.

The locking device 14 is disposed between the telescopic surface lattice main body 1 and the pair of at least one of the guide rails 13.
Reference numeral 4 denotes a guide rail 13 which is rotatably disposed at a predetermined position in a longitudinal direction of the guide rail 13 by operating a lever handle 16 and which can be freely engaged and disengaged with a lock receiver 18 provided on any of the oblique bars 3 of the telescopic surface lattice body 1. The expansion / contraction surface lattice body 1
And the turning radius of the lever handle 16 for operating the lever handle 16 is set to intersect with the sash door B.

That is, since the one end bar 3 is fixed to the guide rail 13, as described above, the oblique bar 2 cannot be moved at the intermediate position in the expansion / contraction direction by the lock device 14. If at least the locking is performed so as not to be movable in the contraction direction, the elastic lattice body 1 which is linked as described above is restricted by the link, and as a result, the elastic movement of the elastic lattice body 1 is restricted. The opening and closing due to the expansion and contraction is prevented, whereby the extended and closed state as a surface lattice is secured in normal times so that it can be used as a partition.

In this embodiment, the lock device 14 includes a holder-like mounting member 15 fixed to, for example, the lower guide rail 13, and a lever handle 16 rotatably supported by the mounting member 15. Among the C-shaped, L-shaped, U-shaped, etc., which are installed at the tip of the lever handle 16, for example, a C-shaped hooking locking portion 17 and a lock receiver 18 installed on the inclined bar 2 are provided. The locking device 14 is adapted to be able to engage and disengage with the intersection of the oblique bar 2 by the rotation of the lever handle 16. At the middle position in the stretching direction
In the extended closed state, the lever handle 16 is overlapped with the lock receiver 18 of an arbitrary crossbar 2 located in front of the sash door B at the position of the lock receiver 18 of the crossbar 2 in this example, and the locking device 14 is locked.
The lever handle 16 is arranged in an inclined shape so as to prevent exposure and conspicuousness.

At this time, the turning radius of the lever handle 16 of the lock device 14 is determined by
Is formed so as to intersect with the sash door B by forming the length of the lever handle 1 longer than the distance between the pivotal support position and the sash door B.
6 and raises the lock device 14 to the lock receiver 1 of the oblique beam 2.
8 while rotating the lever handle 16 to a position where it intersects the sash door B.
4 is removed from the lock receiver 18 of the inclined bar 2 and is released to the indoor side of the stretchable surface lattice body 1 so that it can be released. When the sash door B is opened and escaped in an emergency, The lever handle 16 can be pivoted downward to easily unlock the lock device 14 so that the telescopic surface lattice body 1 can be telescopically opened and closed, in particular, can be reduced and opened, thereby ensuring an emergency exit. The operation of the lever handle 16 from the outdoor side is disabled, so that security can be ensured.

The anti-flap member 10 which is detachable from the pair of parallel guide rails 13 is disposed on the entire or a part of the oblique bar 2 of the elastic surface lattice main body 1, and the elastic surface lattice main body 1 is extended and closed. In this example, the anti-fretting member 10 is provided with the rail fixing portion 11 and the engaging / disengaging portion 1 in the same manner as in the guide member 7.
2 and a part of the elastic surface lattice main body 1 is formed as a piece of the synthetic resin integrally molded piece, and is formed into one of the alternately inclined bars 2 and intersects with the pair of parallel guide rails 13 extended and closed. It is installed at the upper and lower end positions so as to project toward the guide rail 13 side, respectively.
At this time, the anti-fretting member 10 of the present example includes a flat plate-shaped fixing portion 11 and an engaging and disengaging portion 12 which is slightly inclined forward from the fixing portion 11 and protrudes in an L-shape. Is in contact with the back surface of the oblique beam 2 and is screwed to the groove avoiding the C-shaped cross section, and the L-shaped hook engaging / disengaging portion 12 is directed downward at the upper end side of the oblique beam 2. By arranging the L-shaped hook engaging / disengaging portion 12 upward at the lower end side, the pair of parallel guide rails 13 are engaged or locked in a hooking or holding shape from the outside, respectively, and can be freely engaged and disengaged therefrom. In this way, the stretchable surface lattice body 1 can be fixed to the guide rail 13 in the stretched and closed state, while the stretchable surface lattice body 1 is opened and closed. When the position of the stop member 10 is displaced, Then, in this example, the anti-friction member 10 escapes in the vertical direction to prevent the occurrence of frictional resistance due to the anti-flap member 10 due to opening and closing, and improves the security by the anti-fretting fixation in the engaged state. Furthermore, the opening and closing of the elastic surface lattice body 1 can be performed as lightly and smoothly as possible in an emergency.

Although the illustrated example is as described above, the design is changed by using a front curved, wavy oblique beam instead of the above-mentioned straight oblique beam for the elastic lattice body of the elastic surface lattice body. That the locking device is disposed between the guide rail and the other end rail that is movable on the other side, and that the anti-flap member is disposed on all the inclined rails;
The location of the anti-fretting member shall be the intersection of the oblique beams,
When the lock device is operated by a lever handle, the installation of the lock receiver is omitted, and the lock device is configured so as to be freely disengageable at the intersection of the inclined rails and restrained by the link as described above. The lever handle of the lock device is set upright so that the latch portion is latched at the intersection of the oblique bars, or the lever handle of the locking device is installed at an angle in the same manner as described above, while the latch portion is attached to the lever handle. It is to be tilted and rotated so as to be hooked and locked at the intersection of the oblique bars. When the lock receiver is used, the lock receiver is also set upright on the inclined opening and the lever handle of the lock device is erected. In the case where the locking device is to be as described above, a bar is erected as a mounting member between a pair of parallel guide rails, and a lever handle is directly or interposed between the bar. The end crosspiece is a horizontal crosspiece, and a pair of parallel guide rails are arranged in the vertical direction so that the expansion and contraction surface lattice body can be opened and closed in the vertical direction.
