DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure for slidingly moving a double-folding door with the double-folding door being closed.

[Prior Art] Japanese Utility Model Laid-Open No. 62-11977 has been known as a device for fixing a double-folding door when the double-folding door is closed. The one disclosed in Japanese Utility Model Laid-Open No. 62-11977 is a two-fold folding door in which two panels are foldably connected by a hinge member, and a hole is made in the upper part near the hinge member, and a spring is used to move the hole upward. When the two-fold door is closed, the roller elastically engages with the upper rail and locks the two-fold door when the fixture equipped with both the elastically biased roller and the stopper member is fitted and attached. Further, the stopper member is brought into contact with the side surface of the upper rail to prevent the double-folding door from being forcibly bent to the opposite side when an external force is applied.

[Problems to be solved by the invention] However, in the above-mentioned conventional example, since the protruding position of the roller is located at a position deviated from the intermediate position of the double-fold door, when the double-fold door is opened and closed. There was a problem that it was difficult to smoothly fit and disengage the rollers from the upper rail. Further, since the fixing tool is provided with the rollers and the stopper member and fitted into the holes provided in the panel, the positional error between the groove of the upper rail and the side surface of the upper rail, the positional error of the hole provided in the panel, the fixing There is a problem that due to an error in accuracy of the tool, for example, when the stopper member hits the side surface of the upper rail, the roller may not be completely fitted in the groove of the upper rail. Moreover, the conventional double-fold door is merely fixed at a fixed position and opened / closed, and cannot be smoothly slid while the double-fold door is closed (for example, actual opening).

The present invention was devised in view of the above-mentioned conventional problems, and the purpose thereof is to smoothly fit and disengage from the upper rail of the roller, and further to adjust the mounting position when mounting the stopper member. By doing so, despite the provision of the stopper member, the roller can be securely fitted to the upper rail, and the sliding door can be smoothly slid while the double-folding door is closed. It is in providing structure.

[Means for Solving the Problems] The door-stop structure of the two-fold folding door of the present invention is the upper part of the hinge member 2 in the two-fold folding door 3 in which two panels 1 are foldably connected by a hinge member 2. And a stopper member 6 fixed to the upper surface of the end of the panel 1 in the vicinity of the hinge member 2.
The roller 5 is fitted in the groove 8 of the upper rail 7 on which the double-fold door 3 travels so that the stopper member 6 abuts on the side surface of the upper rail 7 and is opposite to the hinge member 2 of the double-fold door 3. An upper traveling member 12 and a lower traveling member 13 are provided above and below the end on the side, and the upper traveling member 12 is movably fitted to the upper rail 7 and the lower traveling member 13 is movably fitted to the lower rail 14. A projecting strip 16 is formed on the outer surface of the upper rail 7 in the longitudinal direction so as to be slidably contactable with the stopper member 6. By adopting such a configuration, the above-mentioned object of the present invention is achieved. It was done.

[Operation] By providing the roller 5 on the upper part of the hinge member 2, the roller 5 is positioned in the middle of the double-fold door 3, and when the double-fold door 3 is opened and closed, the upper rail of the roller 5 is opened. 7
It is possible to smoothly fit into and disengage from the roller, and to install the roller 5 on the upper part of the hinge member 2,
Since the stopper member 6 is fixed to the upper surface of the end of the panel 1 in the vicinity of the hinge member 2, by adjusting the mounting position of the stopper member 6, the roller is surely fitted to the upper rail 7 even though the stopper member 6 is provided. The upper traveling member 12 is provided with an upper traveling member 12 and a lower traveling member 13 above and below an end of the double-folding door 3 opposite to the hinge member 2. Is fitted into the upper rail 7 so that it can travel freely, and the lower traveling member 13 is attached to the lower rail 1.
Since the double folding door 3 is slidably mounted on the upper rail 7 and the lower rail 14, the stopper member 6 on the side of the double folding door 3 has the upper rail 7 By slidingly contacting the ridges 16 on the outer side surface with point contact, the resistance between the stopper member 6 and the upper rail 7 can be made as small as possible.

[Embodiment] The present invention will be described in detail below with reference to an embodiment. As shown in FIG. 1, two panels 1 are foldably connected by a hinge member 2 to form a two-fold folding door 3. A roller unit 15 is fitted and attached to the upper part of the hinge member 2. A rotatable roller 5 is attached to the upper part of the roller unit 15 so as to be vertically movable, and the roller is elastically biased upward by a spring installed in the roller unit 15. A stopper member 6 is fixed to the upper surface of the end of the panel 1 near the hinge member 2. The stopper member 6 is formed by projecting an abutting portion 11 upward from the end of the laterally-fixed fixing piece 9, and the fixing piece 9 is fixed to the upper surface of the panel 1 by a fixing tool 10 such as a screw. In this case, the stopper portion 6 is attached so that the contact portion 11 is located on the protruding side when the double-folding door 3 is folded. As the stopper member 6, an L-shaped metal fitting as shown in FIG. 2 or a shaft protruding from the end of the fixing piece 9 as shown in FIGS.
It may be one in which a roll to be 1 is rotatably supported. In this case, the upper surface of the roll may be hemispherical as shown in FIG. An upper traveling member 12 and a lower traveling member 13 are provided above and below the ends of the two panels 1 opposite to the hinge member 2, respectively. The upper traveling member 12 is fitted in the upper rail 7 so as to be freely movable, and the lower traveling member 13 is attached to the lower rail 14.
It is fitted so that it can run freely.

When the double-folding door 3 having the above structure is closed, the roller 5 first fits into the groove 8 of the upper rail 7, and in this state, the contact portion 11 of the stopper member 6 abuts the side surface of the upper rail 7. is there. The roller 5 is fitted in the groove 8 of the upper rail 7 to prevent the double-fold door 3 from opening naturally. Further, since the hitting portion 11 hits the side surface of the upper rail 7, the hitting portion 11 serves as a stopper during the closing operation so that the panel 1 will not be pushed over the upper rail 7 to the opposite side. Therefore, even if an external force is applied to the panel 1 in the closed state, the contact portion 11 hits the side surface of the upper rail 7 so that the double-fold door 3 will not be folded in the opposite direction. On the other hand, when the double-folding door 3 is opened, an external force is applied so as to fold the double-folding door 3, so that the roller 5 is released from the groove 8 of the upper rail 7 against the spring force of the spring and is folded. is there.

By the way, when the double-folding door 3 is closed, the stopper member 6 is attached to the upper surface of the panel 1 so that the contact portion 11 just hits the side surface of the upper rail 7 with the roller 5 fitted in the upper rail 7. It is adjusted and installed,
By doing so, the state where the contact portion 11 hits the upper rail 7 and the roller 5 is not yet fully fitted in the groove 8 of the upper rail 7 does not occur.

If the ridge 16 having an arc-shaped cross section is provided on the side surface of the upper rail 7, the contact portion 11 will hit the arc-shaped surface of the ridge 16 having the arc shape, and will hit an unspecified portion of the side surface of the upper rail 7. The part 11 does not scratch and rub against it. In this case, if ridges 16 are provided on both side surfaces of the upper rail 7 as shown in FIG. 7, when the two-fold folding door 3 is foldably attached to the upper rail 7, the protruding direction when folded is reversed. Even if it is constructed in this way, the contact portion 11 will hit the ridge 16 on the opposite surface. That is, as shown in FIGS. 5 and 7, in the structure in which the double-fold door 3 is slidable along the upper rail 7 and the lower rail 14, the double-fold door 3 is kept closed. When the slide door is slid, the stopper member 6 of the double-folding door 3 prevents the double-folding door 3 from being reversely folded by the outer surface of the upper rail 7, and the rollers of the double-folding door 3 are located on the upper rail 7. Since it is fitted in the groove, the double-folding door 3 is slidably moved in a stable state, and the stopper member 6 on the side of the double-folding door 3 comes into surface contact with the outer surface of the upper rail 7. Rather, the sliding contact with the ridge 16 formed in the longitudinal direction of the outer side surface reduces the resistance between the stopper member 6 and the upper rail 7, and facilitates the sliding movement of the double-fold door 3. There are advantages.

Further, when the contact portion 11 is a roll, it is possible to further prevent the side surface of the upper rail 7 from being scratched. In particular, when the double-folded door 3 travels along the corner rail portion 7a of the upper rail 7, the contact portion 11 travels while hitting the side surface of the corner rail portion 7a of the upper rail 7 as shown in FIG.
In this case, when the contact portion 11 is a roll, the upper rail 7 is not damaged. If the upper surface of the roll is hemispherical, even if the upper end of the roll, which is the hitting portion 11, contacts the ceiling member or the like when the double-folding door 3 is opened and closed, the upper part of the hemispherical surface comes into contact with the ceiling. It does not damage the members. If the roll is made of an elastic material, it is possible to prevent scratches. In order to prevent the ceiling member from being scratched, the stopper member 6 may be shaped as shown in FIGS. 12 and 13 in addition to the above embodiment.

Reference numeral 17 in FIG. 3 is a lower stopper attached to the lower portion of the hinge member 2, and the stopper 17 is projected downward and inserted into the lower rail 14 with the double-folding door 3 closed. Lower stopper 1 when opening the folding door 3
7 is pulled up.

Further, as shown in FIG. 11, an inclined portion is provided on the lower portion of the side surface of the upper rail 7, the contact portion 11 is inclined corresponding to this inclined portion, and the inclined contact portion 11 is applied to the inclined portion of the upper rail 7. You may

[Effect of the Invention] According to the present invention, as described above, the hinge member is attached to the upper portion of the hinge member and elastically biased upward, and the stopper member fixed to the upper surface of the panel end portion near the hinge member. Since the roller fits in the groove of the upper rail through which the double-fold door travels, and the stopper member abuts the side surface of the upper rail, the roller is positioned in the middle of the double-fold door. When opening and closing the double folding door, the rollers can be smoothly fitted into and disengaged from the upper rail, and the rollers are attached to the upper part of the hinge member, and the stopper member is fixed to the upper surface of the panel end near the hinge member. Therefore, by adjusting the mounting position of the stopper member, the roller can be reliably fitted to the upper rail despite the provision of the stopper member. Further, an upper traveling member and a lower traveling member are provided above and below an end portion of the two-fold door opposite to the hinge member, and the upper traveling member is movably fitted to the upper rail and the lower traveling member is attached to the lower rail. Sliding smoothly with the double-folding door closed with a ridge that is fitted so that it can travel freely and that can be slidably contacted with the stopper member on the double-folding door side in the longitudinal direction of the outer surface of the upper rail. It can be moved.
