As shown in FIG. 6 and FIG. 8, each of the drawing grooves 15 and 16 has a drawing side end (FIG. 8) so as to tighten the guide pieces 13 and 14 when the movable surface grid 7 is drawn to the closed position. , Only the end of the recessed groove 16 on the side of the lower horizontal frame 3 is indicated by 16a). In detail, as can be seen from FIG. 8, the retraction-side end 16 a of the retraction groove 16 forms an arc-shaped fitting portion in which the guide piece 14 is press-fitted when the movable surface lattice 7 is retracted. Retracted end 1 5 a retraction groove 15 of the upper lateral frame 2 side, to form an arc-shaped fitting portion similar to the retracted end 16a of the lower lateral frame 3 side pull grooves 16.

In order to connect each of the recessed grooves 15 and 16 to each of the guide grooves 11 and 12, the recessed groove forming block 2 having the recessed grooves 15 and 16 of a predetermined shape is formed.
2 is attached to required portions of the upper and lower horizontal frames 2 and 3 to obtain a state as shown in FIG. In addition, this drawing groove forming block 2
2 has a slightly different shape between the guide piece 13 attached to the door end side end of the movable surface lattice 7 and the guide piece 13 attached to the door end side end. That is, the drawing groove forming block 22 shown in FIGS. 3, 6 and 8 is a block attached to the end portions of the upper and lower horizontal frames 2 and 3.
2 is provided with a stopper 23 for reliably drawing the guide piece 14 into the drawing groove 16 at a position where the drawing groove 16 branches from the guide groove 12, but is provided between the upper and lower horizontal frames 2 and 3. In the recessed groove forming block 22 attached to the portion, the door-side guide piece 14 of the movable surface lattice 7 does not enter the recessed groove 16 and passes through the branching portion of the guide groove 12 as it is, so there is no stopper as described above.

As can be seen from FIGS. 9 to 11, the upper surface of each drawing groove forming block 22, that is, the upper end surface of the drawing groove 16, is a guide surface 19 for guiding the guide roller 20.
The guide rollers 20 are formed at a slightly lower level than the guide rollers 20 when the guide pieces 13 and 14 of the movable surface lattice 7 are guided into the recess grooves 15 and 16. This is because if the upper surface of each recess groove forming block 22 is at the same level as the upper end surface of the recess groove 16, when the movable surface grid 7 is retracted to the closed position or when the movable surface lattice 7 is opened and moved from the closed position, the guide roller 20 It becomes a state of skidding while rubbing the upper surface of the block 22,
This is because this will hinder the operation of pulling in or pulling out the movable surface lattice 7.

In the use of the emergency escape surface grating having the above-described configuration, the movable surface grating 7 is always in the state shown in FIG.
As shown in FIGS. 2 and 3, the vertical frame 5 of the outer frame 1 is locked by a suitable locking device (not shown) in a closed position that is flush with the fixed surface grid 6. Of course, in this case,
The unlocking operation of the movable surface lattice 7 cannot be performed from outside the room.

In an emergency such as a fire, the locking device is unlocked from the indoor side, and the movable surface grid 7 in the closed position as shown by the solid line in FIG. 3 and FIG. The guide pieces 13, 1 of the movable surface grid 7 are drawn by vigorously pulling it toward the indoor side while being drawn toward the surface grid 6.
The movable surface lattice 7 is easily and quickly moved to the open position as shown in the phantom line in FIG. 3 and in FIG. 5 and further in FIG. It can be opened and moved, so that FIG.
The emergency escape opening S can be formed by forming the emergency escape opening S shown in FIG.

When closing the movable surface lattice 7 which has been opened and moved as described above, the movable surface lattice 7 at the open position where the guide pieces 13 and 14 are fitted into the guide grooves 11 and 12 is pulled in the closing direction. By moving, the guide pieces 13 and 14 are drawn in from the guide grooves 11 and 12 to the drawing grooves 15 and 16, and the movable surface lattice 7 is returned to the closed position as shown by the solid line in FIG. 3 and FIG. be able to.

In this case, since the retracted side ends of the retractable grooves 15, 16 form an arc-shaped fitting portion for press-fitting the guide piece 14, when the movable surface lattice 7 is retracted to the closed position. The door-side guide pieces 13 and 14 of the movable surface lattice 7 are fitted into the arc-shaped fitting portions at the retracted ends of the recess grooves 15 and 16 in a press-contact state, thereby smoothly moving the movable surface lattice 7 to the closed position. The movable surface grid 7 can be securely fixed at a fixed position without rattling of the movable surface lattice 7 in the closed position, and the movable surface lattice 7 can be returned to the closed position with vigorous pulling. The door-side guide pieces 13 and 14 of 7 can be fitted and fitted to the draw-in side ends of the draw-in grooves 15 and 16 as if they were sucked, and can be instantly stopped and fixed.

By the way, the width of the recessed ends of the recessed grooves 15 and 16 is wider than the outer diameter of the guide pieces 13 and 14, and the guide pieces 13 and 14 are loosely fitted to the recessed ends. When the movable surface lattice 7 is returned to the closed position, the movable surface lattice 7 cannot be fixed instantaneously, and there is no backlash even when the movable surface lattice 7 is locked in the closed position. This may cause noise due to wind pressure or the like, and when the moving surface grid 7 is vigorously pulled into the closed position, the door-side guide pieces 13, 14 of the movable surface grid 7 are pulled into the drawing grooves 15, 16. There is an inconvenience that the movable surface grid 7 vibrates due to a strong collision with the end portion, and the movable surface grid 7 is opened and moved due to the reaction of the collision.

In this embodiment, the retracted ends of the recessed grooves 15, 16 form an arcuate fitting portion. However, the retractable end is not limited to the arcuate fitting portion, but is movable. When the surface grid 7 is pulled into the closed position, the guide pieces 13, 1
Any structure may be used as long as it acts to tighten the groove 4. For example, both sides of the groove end may be tapered so that the groove end has an inverted C-shape or an inverted trapezoidal plan view.

Further, the guide pieces 13 and 14 are provided at two positions, that is, a door end side end and a door end side end of the movable surface grid 7. Since the movable surface grid 7 can be opened and moved in a stable state, since it is provided at a position corresponding to each of the guide pieces 13 and 14 provided at the front end and the door end, respectively, the opening movement operation can be performed. In addition, the retracting operation to the closed position can be easily and quickly performed.

At the lower end of the movable surface grid 7, a guide roller 20 that rolls on a guide surface 19 provided along the guide grooves 11, 12 at a position near the guide pieces 13, 14.
Is provided, the movable surface lattice 7 can be moved smoothly and in a stable state at the open position.

In the embodiment described above, the fixed surface grid 6 is mounted on one side of the outer frame 1 and the movable surface grid 7 is provided on the other side. The movable surface grid 7 may be of a pull type. Also,
In this embodiment, a louver-type surface grating is used as the movable surface grating 7.
Ordinary plane grids composed of vertical grid members and horizontal grid members can be used.
