Description

[Detailed description of the invention] [Industrial applications]

The present invention relates to a structure of a lower rail of a partition device in which a plurality of panels are foldably connected and the panels are movably mounted along upper and lower rails.

[Prior art]

BACKGROUND ART Conventionally, as a partition device such as a folding door, an opening / closing wall, a partition device in which a plurality of panels are foldably connected by a hinge body is known. In this partitioning device, the panel is hung on the upper rail at the upper end,
The lower end is guided by the lower rail.

[Problems to be solved by the invention]

In the prior art, as shown in FIG. 8, the lower rail 3 'has a U-shaped cross section, and is fixed to the floor surface by driving the fixing member 8 into the bottom piece 3a'. There is a problem that the lower end of the panel is caught by the fixing member 8 and cannot be opened and closed smoothly. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a structure of a lower rail of a partitioning device which can smoothly open and close a panel by smoothly moving a panel.

[Means for Solving the Problems]

The structure of the lower rail of the partition device of the present invention is such that the adjacent panels 1, 1 are rotatably pivoted to connect the plurality of panels 1, 1 in a foldable manner, and the panel 1 is connected to the upper and lower rails 2,
3 is a structure of a lower rail of the partitioning device A movably mounted along 3, and the lower rail 3 is buried diagonally upward from the outer surface of the upper and lower middle portions of both side pieces 3b, 3b of the grooved lower rail 3. The locking pieces 5, 5 for the buried holding section to be held are provided, and the inner end edges of the sliding contact pieces 3c, 3c which are horizontally extended outward at the upper ends of both side pieces 3b, 3b are substantially circular in cross section. 3c ″, 3
c "is formed, and the enlarged portions 3c", 3c "are provided so as to protrude into the space X formed in the lower rail 3. [Operation] The partitioning device of the present invention is characterized in that: The structure of the lower rail is provided on the outer surfaces of the upper and lower middle portions of both side pieces 3b, 3b of the lower rail 3 with locking pieces 5, 5 which protrude obliquely upward and embed the lower rail 3 with respect to a buried holding portion. The lower rail 3 can be buried and held by locking the locked pieces 5, 5 of both side pieces 3b, 3b of the lower rail 3 to the buried holding portion. This prevents the fixing tool 8 from protruding, and guides the pivot 15 of the partitioning device A by the enlarged portions 3c ", 3c" protruding into the space X formed in the lower rail 3. [Example] The two panels 1 can be freely folded via the hinge body 9. The hinge body 9 is a vertically long extruded product having a U-shape with a lip in cross section made of a synthetic resin or metal, and a pivotal support 11 is provided at each end edge of the opening 10. A pivoted support portion 12 protrudes from one side end of the side end surface of the panel 1. A pivoted support portion 12 of an adjacent panel 1 is provided.
Are pivotally supported by a pivot portion 11 of the hinge body 9 so that the two panels 1 are foldably connected. An end cap 13 having a U-shaped cross section is attached to a side end surface of the panel 1 opposite to a side end portion pivotally supported by the hinge body 9,
Screw the fixing pieces 14a and 15a in this end cap 13 respectively.
A runner 14 and a pivot 15 for running are respectively provided on the upper surface and the lower surface, which are stopped at 16. An end cushion 17 is attached to the end cap 13. Runner 14
The pivot 15 and the pivot 15 are respectively fitted to the upper rail 2 and the lower rail 3 so as to be able to travel. A stopper 18 is detachably attached to one end in the longitudinal direction of the upper and lower rails 2 and 3 by a screw or the like. The stopper 18 prevents one of the runners 14 and the pivot 15 of the panel 1 from running, and the runner 14 and the pivot 15 is the pivot side of the two panels 1 and the hinge body 9
, The panels 1 are folded and spread, and the partition device A, which is a two-fold door, is opened and closed. At the lower part of the hinge body 9, concave portions 19 a on both sides are fitted into the pivotal support portion 11, are fixed with screws 20, and the drop rod case 19 is attached. A dropping rod 21 is stored in the dropping rod case 19, and a connecting tool 22 is inserted into the slide hole 23 of the dropping rod case 19 so as to be movable up and down.
21 is operated up and down. A mounting portion 24a is fitted on the upper portion of the hinge body 9, and a latch 24, which is a roller, protrudes from the upper end. With the partitioning device A closed, the drop bar 21 is fitted into the lower rail 3, and the latch 24 is snapped into the upper rail. The upper rail 2 is attached to the horizontal frame 25 with a mounting piece 26, the rail body 2a has a U-shape with a lip in cross section that opens downward, and the lower part of the side piece 2b in the opening direction of the partitioning device A is inclined. It is a surface 2c and protrudes upward from both side edges of the opening 27. The outer surface of the base of the rising piece 28 is formed to be in contact with the outer peripheral surface of the latch 24. Thus, when the partitioning device A is closed, the latch 24 is guided by the inclined surface 2c and smoothly locked in the opening 27 as shown in FIG. The lower rail 3 has a U-shaped cross section, as shown in FIG. The groove portion 4 may be provided over the entire length in the longitudinal direction, or may be provided partially. 3b on both sides
A sliding contact piece 3c extends substantially horizontally outward from the upper end of the groove 3 and the lower surface of the groove portion 4 is flush with the lower end surface of the side piece 3b. Locked pieces 5 are provided on outer surfaces of both side pieces 3 b of the lower rail 3. Both sides 6a of a substantially U-shaped mounting bracket 6 as a buried holding portion for burying and holding the lower rail 3 are cut and raised on the inner surface side, and a locking piece 7 is projected.
Is fixed to the floor by inserting a fixing tool 8 into the bottom piece 6b, and the lower rail 3 is fitted into the mounting bracket 6 so that the lower rail 3
The locked piece 5 is locked with the locking piece 7. According to such a configuration, there is no obstacle on the inner surface of the lower rail 3, so that the pivot 15 can run smoothly.

[Effect of the invention]

In the structure of the lower rail of the partition device of the present invention,
Since the locking pieces are provided on the outer surfaces of the upper and lower middle portions of both side pieces of the groove-shaped lower rail so as to protrude obliquely upward with respect to the buried holding section for burying and holding the lower rail, the locked pieces are engaged with the buried holding section. By stopping, the lower rail can be buried and held, and there is an advantage that the fixing tool can be prevented from protruding into the lower rail in the buried state of the lower rail. In addition, there is an advantage that the pivot of the partitioning device is guided by the enormous portion protruding into the space formed in the lower rail so that the panel can run smoothly.
