<P>PROBLEM TO BE SOLVED: To provide a horizontal shutter which allows a shutter unit to be integrally held or released with interlock to opening or closing of the shutter unit, having a structure as simple as possible. <P>SOLUTION: Opening preventing members 5 are arranged at upper and lower edges of each suspender side frames 34 rotatably connected to a pair of door bodies 3 having the same width which constitute a shutter unit 2 of a horizontal shutter A. When the shutter unit 2 is folded, the opposed suspender side frames 34 are contacted to each other to lock the opening preventing members 5, allowing the shutter unit 2 to be integrally held. When the shutter unit 2 is extended, the suspender side frames 34 are separated away to release the lock of the opening preventing members 5, allowing the integration due to the lock to be released. The opening preventing members 5 made of a synthetic resin are located in rail grooves for an upper rail 11 and a lower rail 12, allowing the lock and the release of the lock to be interlocked with opening and closing of the shutter unit 2, using elasticity of the synthetic resin. <P>COPYRIGHT: (C)2012,JPO&INPIT |
