安全性の面で一抹の不安が残されていた。 Conventionally, regarding the pivot structure of the front folding door of assembled storage furniture, as shown in Fig. 4, the door frame 2
While the rail 22 is fixed on the floor in front of the lower stile 1, the upper pivot 2 is attached to the pivot side end of the bifold door 23 so as to project upward and downward, respectively.
4 and a lower pivot 25 are pivotally supported by an upper pivot receiver 26 attached to the upper stile of the door frame 21 and a lower pivot receiver 27 fixed to one end of the rail 22. In such a pivot structure, in order to facilitate the assembly work of the door 23, the upper pivot 24 is made retractable downward against a spring. In some cases, the lower pivot 25 is first fitted into the upper pivot receiver 26, and then the door 23 is slightly lifted to allow the lower pivot 25 to ride over the rail 22 and drop into the bearing recess 27a of the lower pivot receiver 27. . However, in this case,
Although it is easy to install the door, if an upward external force is applied to the door 23 for some reason, such as when someone or something hits it from the outside, or when the door 23 is opened or closed roughly.
3 is lifted upward, the lower pivot 25 inadvertently slides into the recess 27a of the pivot receiver 27.
We cannot deny the possibility that the door 23 may come off by detaching it from the
There remained some concerns regarding safety.
この考案は、扉の装着作業性の面での上記利点

折れ状態に開き得るものとなされている。 This embodiment is applied to a pivot structure for a bifold door on the front of assembled storage furniture.As shown in FIG. A door frame 2 assembled into a correspondingly sized square is attached to the front opening edge, and a channel-type rail made of extruded aluminum or the like is fixed to the floor or the like on the front side of the lower stile of the door frame 2. 3 is provided. On the other hand, each of the front folding doors 4 has one
The ends of the pair of door panels are pivotally connected to each other to form a bifold door that can be bent freely, and an upper pivot 5 is attached to the upper end of one side edge on the base end of the rotation. This is fitted into a shaft hole 6a of an upper pivot receiver 6 attached to the upper stile of the door frame 2 and is pivotally supported, and a lower pivot 7 is attached to the lower end of the same in a downwardly projecting manner, and this is connected to the rail 3. It is fitted and pivotally supported in a bearing recess 8a of a lower pivot receiver 8 fixed to one end. Further, a runner 9 is attached to the lower surface of the other side edge of the door 4 in a downwardly projecting manner, and is slidably supported on the rail 3. Therefore, as shown in FIG. 1, the door 4 can be opened in two by rotating around the upper and lower pivots 5 and 7.
上部ピボツト５は、扉４に埋設された保持筒１

ができるようになつている。 The upper pivot 5 is connected to the holding cylinder 1 embedded in the door 4.
0 so as to be able to move up and down, and is always urged upward by a spring built into the holding cylinder.
Therefore, it is possible to retract downward against this spring force.
一方、下部ピボツト７は、第２図に示すように

ある。 On the other hand, as shown in FIG. 2, the lower pivot 7 has an upper male threaded portion 7a screwed into a female threaded cylinder 11 embedded in the door 4, and a polygonal height adjusting portion integrally provided at the lower part. By rotating using the flange 12, the height, that is, the degree of downward protrusion of the lower pivot 7 can be adjusted. 1
Reference numeral 1a denotes a sleeve plate for mounting that is integrally provided with the female threaded cylinder 11, and is fixed to the lower surface of the door with screws or the like.

It consists of a metal plate piece having 8b, and the rail 3
It is placed on opposing convex edges 3a, 3a provided on both sides of the upper part of the groove part 13, and one end part is placed on the upper sides of the groove part 13.
It is fixed to the rail 3 by a fixing bolt 15 screwed into a nut piece 14 fitted inside.

ａから脱外するおそれがある。 The above configuration is as conventionally known, but if the door 4 moves upward for some reason and the upper pivot 5 moves back and forth against the spring for its extension, the lower pivot 7 will move into the lower pivot receiver 8. recess 8
There is a risk of falling off from a.

るものとなつている。 Therefore, in this invention, the lower pivot 7
A locking plate 16 that absolutely prevents excessive upward movement of the
is added. This locking plate 16 is made of a metal plate piece formed in a round shape when viewed from the side, and as shown in FIGS. 2 and 3, one end thereof is attached to the fixing bolt 15 on the lower pivot receiver 8. It is integrally and removably fixed to the rail 3 by using the U-shaped notch 17 provided at the other end at a position slightly above the height adjusting collar 12. A portion of the lower pivot 7 is fitted. Therefore, the lower pivot 7 is connected to the locking plate 16 of the flange 12.
Its locking action prevents its upward movement.
上記鍔部１２の代りに、ピボツト７の一部に切
欠溝をして、該溝部分に係止板１６の切欠部１７
をしつくりとはめ合わせることにより、下部ピボ
ツトの上方移動を阻止せしめるものとしても良
い。 Instead of the flange 12, a notch groove is formed in a part of the pivot 7, and the notch 17 of the locking plate 16 is inserted into the groove.
It may also be possible to prevent the lower pivot from moving upward by fitting together.
なお、扉４の着装に際しては、一旦固定ボルト

きるようにすることもある。 When installing the door 4, first loosen the fixing bolt 15 and rotate the locking plate 16 backward to release it, and after fitting it into the recess 8a of the lower pivot 7, return it to the predetermined position and tighten the fixing bolt 15. Needless to say, it is used for tightening and fixing. Further, by forming the fixing bolt penetration portion of the locking plate 16 with a U-shaped notch or the like, the locking plate 16 can be attached after fitting into the recess 8a of the lower pivot 7. You can do it like this. If the locking plate 16 hits the lower frame and is difficult to rotate backwards, prepare right-hand and left-hand fittings so that the locking plate 16 can be rotated forward and released. There is also.
この考案は上述の次第で、扉４の不慮の上方移

きる等の利点がある。 This invention, as described above, eliminates the risk of the lower pivot 7 escaping from the recess 8a and the door coming off due to an accidental upward movement of the door 4, which not only improves safety but also makes it easier to install the door. It has the advantages of simplicity and opening/closing operation without causing any hindrance, and that it can be easily implemented by using the conventional pivot structural parts as they are and adding only the locking plate.
