As a result, the above objective was achieved.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. 1 is a panel, and an aluminum frame member 2 is attached to the outer peripheral surface of the panel 1. On the side surface of the panel 1 on the connection side, a hinge piece 3 having a cross section of "C" is protruded from the frame material 2, and on the free side surface, a gasket attachment part 4 with a semicircular notched cross section is protruded. ing. The hinge frame 5 for connecting the hinge pieces 3 is made of aluminum and has a substantially U-shaped cross section, and the hinge frame 5 has small cylindrical hinge pin portions 6 on the inner side at both ends.
is provided. Then, the hinge piece 3 is inserted into the hinge frame 5 so as to wrap around the hinge pin part 6, and the spacer 7 is press-fitted into the hinge frame 5 so that the hinge piece 3 can rotate smoothly without rattling. The hinge piece 3 is designed so that it will not come off from the hinge frame 5 even if it rotates. In this way, a door panel 8 that can be folded in a zigzag pattern is constructed by rotatably connecting a plurality of panels 1. A gasket 9 is attached. Here, the tongue piece 10 at the end of the seal 9 is panel 1

The figure shows a latch device 1 having the above-mentioned latch roller 26.
7 is shown. That is, a guide spacer 22 is installed inside a cylindrical case 21 so as to be slidable along the axial direction of the case 21, and a coil-shaped spring 23 is installed between the bottom surface of the case 21 and the lower surface of the guide spacer 22. Interpose guide spacer 2
2 is urged upward, and the upper opening of the case 21 is closed with a plate 29. A through hole 30 and a through hole 3 are provided in the centers of the guide spacer 22 and the plate 29, respectively.
1 is open. One or two grooves 24 are formed along the axial direction on the outer peripheral surface of the guide spacer 22.
A protrusion 25 protruding from the inner surface of the case 21 is fitted into the groove 24 so that the guide spacer 22 can slide within the case 21 but cannot rotate. Reference numeral 27 designates a latch pin, which has a driver groove 32 at its upper end, a rotatable latch roller 26 attached to its upper end, and an E-ring 3.
It is stopped by 3. A male threaded portion 28 is provided at the lower end of the latch pin 27.
The latch roller 26 is attached to the case 21 by tapping it through the through hole 31 into the through hole 30 (which may or may not have an internal thread) of the guide spacer 22. Since the guide spacer 22 does not rotate at this time, the latch pin 27 can be easily screwed into the guide spacer 22, and the protrusion of the latch roller 26 can be adjusted by changing the screw-in depth. The latch device 17, which has been made into an integral part in this way, is inserted into the upper end of the spacer 7 of the hinge portion 16 and fixed with screws or the like.

However, this latch roller 26 is connected to the door panel 8.
When the door panel 8 is extended, it fits into the opening of the upper rail 12 to keep the door panel 8 flat, and when the door panel 8 is folded, it escapes from the upper rail 12 and becomes free, and when the door panel 8 is extended again, the upper rail 12 It is once retracted downward by the inclined surface 34 of the upper rail 12 and is fitted into the opening of the upper rail 12.

[Effects of the invention] As described above, the present invention includes hinge pieces protruding from the connecting side surfaces of the panels to be connected, and hinge pin portions formed at both ends of the hinge frame having a substantially U-shaped cross section. In a latch device used for a partition door, in which a spacer is press-fitted into the hinge frame to engage the hinge piece and prevent the hinge piece and the hinge pin from coming apart, the spacer is used to connect the panels in a rotatable manner. A cylindrical case with a bottom that is fixed to the upper end of the case other than the one to which the runner is attached so as to be freely movable on the rail, and a guide spacer that is housed in the case so as to be slidable in the vertical direction but not rotatable. , a spring that is inserted between the bottom of the case and the guide spacer and urges the guide spacer upward; a latch pin that has a male threaded part formed at its lower end that is screwed into the guide spacer so that it can freely protrude and retract; and the upper end of the latch pin. Since it is equipped with a latch roller that is rotatably attached to the holder, it can be easily assembled by assembling the case side and the latch roller side separately and then screwing the latch pin into the guide spacer. It is made into parts,
Furthermore, since the case side is attached to the spacer of the hinge part that connects the panels, there is an advantage that it can be easily assembled into the door panel. Moreover, it has the advantage that the height of the latch roller can be easily adjusted by rotating the latch pin.

In addition, since the male screw part that is screwed into the guide spacer so that it can freely come out and go out has a latch pin formed at the lower end, the amount of protrusion of the latch roller can be adjusted by adjusting the screwing amount of the latch pin. Since it is rotatably attached to the top end, the rotational force exerted on the latch roller when it is attached and detached from the rail is not transmitted to the latch pin, and the amount of protrusion of the latch roller changes during long-term use, making it difficult to fold the panel smoothly. It also has the advantage of not causing problems. Furthermore, since the latching device is attached to the hinge portion that connects the panels, the latching rollers move substantially perpendicularly to the rails, so there is an advantage that the folding operation of the panels can be performed smoothly.
