A more detailed description will be given below with reference to the embodiments shown in FIGS. The one side member 20 facing the base member 11 and the groove member 31 are integrally formed by bending a metal plate. The end edge side of the base member 11 is bent to form a guide member 22 facing the side member 20 in parallel, and a guide groove 23 continuing in the length direction of the base member 11 is provided between the side member 20 and the guide member 22. The slider 32 is slidably fitted in the guide groove 23 in the direction from the base member side (11) to the groove member side (21).

The slider 32 is formed by bending a metal plate, and a part of the slider 32 constitutes the groove member 31 and the other side member 30 facing the side member 20 and the groove member 31.
That is, the metal plate is bent at two right angles, and one of the two bending tongues 37 and 38 (37) facing each other in parallel constitutes the side member 30 which is long projected, and the end side thereof is bent inward. The other groove member 31 is formed as the other, and the outer dimension B of the bent tongue pieces 37 and 38 facing in parallel is matched with the inner dimension (B) of the guide groove 23, and the base member side (11)
The slider 32 is slidable in the direction from the groove member side (21) to the groove member side (21), and when the slider 32 is guided and moved by the side member 20 and the guide member 22, the groove member 31 also moves.

On the outside of the base member 11, the base member 1
1, a moving member 15 is mounted so as to be movable in the length direction, and one end of the moving member 15 is connected to an operating portion 35 of a driving device 15 such as an air cylinder or a solenoid through a string, a rod, a wire, a piano steel wire or the like 36. The moving member 15 is connected and is pulled by the driving device 15 in the longitudinal direction of the base member 11.

The base member 11 and the moving member 15 have openings 16 and 1 which are vertically overlapped and penetrated toward the running groove side (12).
No. 8 is opened, and in these openings 16 and 18, a hook member 19 of a hook 24 protruding toward the upper end side of a peripheral edge 26 of the opening 16 of the moving member 15 has a hook tip in the longitudinal direction of the base member 11. And the lower end of the hook member 19 has a slider 32 connecting the left and right bent tongue pieces 37 and 38.
It is screwed to the connecting member 39. Base member 11
A spring 40 is fitted in the gap between the connection member 39 and the connection member 39, and the connection member 39 is elastically biased in a direction away from the base member 11.

The height dimension H of the bent tongue piece 38 facing the side member 30 is made sufficiently smaller than the depth dimension D of the guide groove 23 so that the groove member 31 together with the slider 32 has the groove width (A) of the running groove 12. Allows large movement in the direction perpendicular to. Height dimension E from hook 24 of hook member 19 to slider 32
Is set so that there is a sufficient gap 41 between the connecting member 39 of the slider and the base member 11 to sandwich the spring 40.

The groove member 31 moves the moving member 15 and hooks the hook tip 24 to the peripheral edge 26 of the moving member 15 to fix it, and in the fixed state, it faces one of the groove members 21 and runs in the running groove 12. And the curtain 34 is hung by engaging the runner 13 therewith.

In such a state in which the hook tip 24 is oriented toward the length of the base member and hooked on the opening peripheral edge, the moving member 15 is pulled by the drive unit 14 to move the hook tip 24 from the opening peripheral edge 26 of the moving member 15. When the slider 32 is removed, the slider 32 is elastically biased by the spring 40 and slides away from the base member 11, the groove member 31 moves in the direction perpendicular to the running groove 12, the groove width A widens, and the runner 13 moves. When the curtain 34 comes off from the curtain 12, the curtain 34 and the runner 13 fall from the curtain rail 33. Therefore, the drive device 14
Is linked to the sprinkler, the sprinkler is activated during a fire, and at the same time, the curtain 34 falls and is less likely to be exposed to flames.

In this case, the side member 3 together with the slider 32
0 and the groove member 31 do not fall out of the guide groove 23, so that the length dimension F of the opening 16 of the moving member 14
Is the dimension G near the tip of the hook member 19 in the length direction.
The hook 25, which is slightly larger than the hook 24 and whose hook tip is in the opposite direction to the hook 24, is formed on the base member 11 more than the hook tip 24.
It is preferable to attach it to the upper side away from the slider 32. When the slider 32 descends, the reverse hook 25 catches on the other peripheral edge 27 of the moving member 15 and stops.
Will not come off from the guide groove 23. 43 in the figure
Is a curtain rail upper cover that covers the base member 11 and the hook member 19.

FIG. 6 illustrates another embodiment for preventing the slider 32 from falling off the guide groove 23. That is, the moving member 15 is made of a square pipe and has an opening 16
・ 17 is double-sided. From the hook member 19, two hooks 24 and 25 having hook points directed in opposite directions to each other in the length direction of the base member 11 are projected, and when one hook 24 is caught on the peripheral edge 26 on one side of the upper opening 16. The other edge 27 is far away from the other tip 25 and the lower opening 1
The lower peripheral edge 28 of the hook 24, which is caught by the peripheral edge 26 of the upper opening 16 among the two peripheral edges 28 and 29 facing each other, is far away from directly below the tip 24 of the hook, and the other peripheral edge 29 is It is approaching just below the unhooked hook 25.

Therefore, the moving member 15 is the base member 11
Move in the direction of the length of the hook 2
When 6 is disengaged from the peripheral edge 26, the hook member 19 falls below the upper opening 16, but when the moving member 15 moves in this way, one of the lower openings 17 is provided just below the hook tip 25 that has not been caught until then. Since the peripheral edge 29 of the hook comes in, the other tip 25 of the hook that has not been hooked until then moves and is hooked at the peripheral edge 19 of the lower opening 17 that has come directly below, and the hook member 1
The fall of 9 is to stop.

The hook member 19 can be pulled out from the opening 16 (17) by further moving the moving member 15 in the opposite direction, so that the slider 32 is inserted into the guide groove 22 in the length direction of the base member 11. , The slider 32 is pushed up to the base member side (11) against the reaction force from the spring 40, and the hook member 19 is opened to the upper side of the base member 11.
When projecting from and pulling out from the base member 11, the moving member 15 is moved back and forth in the longitudinal direction of the base member 11 in the reverse order to project the hook 24 to the upper side of the opening 16 and hook it on the peripheral edge 26, and the base member 11 and the left and right side members. The curtain rail 33 can be assembled by the 20/30 and the left and right groove members 21 and 31. In the figure, 42 is a hook, and 14 is
It is an air cylinder fixed to the base member.
Is a push rod joined to the moving member.

[0020]

According to the curtain rail 33 of the present invention, at least one of the left and right groove members 21 and 31 is movable in the direction in which the groove width A is expanded or contracted so that the side member 20, the base member 11 or the other member can be moved. Since it is locked in any of the groove members 21, when the drive device 14 is interlocked with the sprinkler, the groove width A widens and the runner 13 is disengaged from the curtain rail 33 and the curtain 34 falls when a fire occurs. It is possible to prevent the spread of the fire due to the flame on the curtain rail 3 and prevent the members 30, 31, 32 of the curtain rail 33 from falling.
3 does not interfere with evacuation activities and fire extinguishing work.

Since the curtain 34 is dropped and removed in the event of a fire, it is not necessary to install a sprinkler for each partition even if the bed is partitioned by the curtain.

Also, since the curtain thus does not interfere with the operation of the sprinkler, it is possible to use a densely woven curtain with a shielding part extending to the upper edge, thereby blocking the convection of air between the beds. The present invention is also advantageous in terms of preventing nosocomial infections.
