Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a closed position regulating device for a folding door, which is foldably connected by a hinge and guided along a guide rail so as to be openable and closable.

[Prior Art] Conventionally, this type of folding door closing position regulating device has a
The structure shown in FIG. 1 is known, as disclosed in Japanese Utility Model Application Publication No. 58-48865. That is, hinges C extending in the vertical direction are attached to the end faces of adjacent folding doors A and B so that they can be folded together, and upper and lower guide rails are provided at the upper and lower left ends of folding door A and at the upper and lower right ends of folding door B. D,
A runner F and a pivot G guided by E are attached, and an embedded hole of a predetermined depth is provided at the upper left end of one of the folding doors B, and the opening of the upper rail D can be freely inserted into and retracted from this embedded hole. A latch member H to engage is embedded. This latch member H has a sliding hole opened upward, and a sliding body is placed from the bottom of the hole via a spring.

[Problem to be solved by the invention] However, in the above conventional structure, when the other folding door A is closed, the other folding door A is in a cantilevered state between the runner F and the latch member H, and the folding door relative to the latch member H is The locking of A is indirect.
For this reason, the folding door A had the disadvantage that it easily rattled and could not be closed flush.

In addition, attaching the latch member H to the folding door not only requires time and effort such as digging into the folding door, but also
It could not be used for folding doors made of materials that could not be dug into. Furthermore, since the principle of simply placing the sliding body on the spring is disclosed, there is a risk that the sliding body will pop out of the sliding hole due to the spring force when the latch is removed from the rail. None of the innovations were disclosed.

Furthermore, since the latch member H is dug into a hole of a predetermined depth, there is a drawback that the amount of latch protrusion cannot be adjusted to obtain an appropriate protrusion.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional situation, an object of the present invention is to provide a closing position regulating device for a folding door that holds the folding door flush when closed and is easy to install and assemble.

[Means for Solving the Problems] The feature of the closing position regulating device for a folding door according to the present invention to achieve the above object is that a long hinge for a folding door is connected to a side plate in a pair with a curtain plate and in a space between the side plates. The latch member is formed into a substantially U-shape in plan view from a pair of plate-shaped pieces integrally protruding from each other, and the latch member is inserted into the space between the side plates of the hinge from above to sandwich and open the plate-shaped pieces in the lateral direction. A pair of fixing plates that are fixed with screws from one side to the other, a guide frame that is erected from one of the fixing plates and has a substantially U-shape and has an elongated hole in the vertical direction, and a spring inside the guide frame. The moving frame is provided with a movable frame which is attached to the elongated hole so as to be retractable while being engaged with a pin, and a latch which is rotatably provided at the upper end of the movable frame.

[Effect]

By interposing a spring in the guide frame and engaging a pin in the elongated hole, the movable frame is removably mounted and the latch member is assembled.

Therefore, when a pair of fixing plates is inserted from above into the space between the side plates of the hinge, the opposing plate pieces are sandwiched between the fixing plates from both edges. Therefore, if you screw the pair of fixing plates while watching the protruding state of the latch from the U-shaped lateral opening of the hinge,
The latch member is installed.

When the folding door is closed, the moving frame is retracted and locked in the rail, so that the latch member evenly locks adjacent folding doors above the hinge.

End surface 2 located on the other surface n side of the folding doors 2 and 3
Bearings 15, 15 are provided at a, 3a, respectively, to which the shaft portion 12 is rotatably mounted. Each bearing 15
has a C-shape in plan view and extends vertically.
One end of the bearing 15 has the other surface n of the end surfaces 2a and 3a.
A strip-shaped mounting plate 16 is integrally protruded from the mounting plate 16 to the one surface m. The mounting plate 16 is fixed to the end faces 2a, 3a with mounting screws 17, 17, . . . , respectively. Therefore, the hinge 1 positions the side plate 11 toward the mounting plate 16 and moves the shaft portion 12 toward the bearing 15.
By fitting, the folding doors 2 and 3 are connected so that they can be folded in two.

Next, a latch member 8 is fixedly projected above the hinge 1. As shown in FIGS. 4 and 5, the latch member 8 includes a pair of fixing plates 80 and 81 that sandwich the support plate 14 of the hinge 1. One of the fixing plates 80 has through holes 8 through which mounting screws 82, 82 are inserted.
0a is opened from the side, and the other fixed plate 81 has screw holes 8 into which mounting screws 82, 82 are screwed.
1a and 81a are similarly opened. A guide frame 83 is provided at the upper end of one of the fixed plates 80 in a U-shape. Bottom plate 8 of guide frame 83
3a is formed by bending the upper end of one fixed plate 80 rearward at a substantially right angle, and the left and right side parts of the bottom plate 83a are raised upward to form a pair of side pieces 83b, 83b of the guide frame 83. ing. Each side piece 8
The front edges of the guide pieces 3b are bent inwardly at substantially right angles to form a pair of guide pieces 83c, 83c.
Each side piece 83b has a vertically elongated elongated hole 83d,
83d is formed.

Inside the guide frame 83, a U-shaped roller frame 84 serving as a movable frame is attached so as to be movable up and down. The left and right pieces 84a, 84a of the roller frame 84 have insertion holes 84b, 8, respectively.
4b are opened at the top and bottom, and the insertion holes 84b, 8
The vertical distance between the holes 4b is smaller than the length of the elongated hole 83d. The roller frame 84 has its side pieces 84
a along the side pieces 83b, 83b of the guide frame 83, and make the upper and lower insertion holes 84b meet a part of the elongated hole 83d, and the two shafts (pins) 85, 85 are inserted into the upper and lower holes from one elongated hole 83d. The roller frame 84 is attached to the guide frame 83 so as to be movable up and down. A compression spring 86 is interposed between the bottom plate 84c of the roller frame 84 and the bottom plate 83a of the guide roller 83. A roller 87 serving as a latch is rotatably mounted between the tops of side pieces 84a, 84a of the roller frame 84 about a shaft 87a.

To explain the effects based on the above configuration,
The folding doors 2 and 3 are closed from the imaginary line to the solid line by an operating force in the opposite direction in the W direction in FIG. 6. At this time of closing, the roller 87 of the latch member 8 attached to the upper end of the hinge 1 is positioned within the opening 5b of the upper guide rail 5 as shown in FIG. 7, and the rail 5a forming the front and rear edges of the opening 5b ，
The roller 87 is brought into contact with the corners 5c, 5c of 5a.
is locked to the guide rail 5 as shown by the solid line.

When the folding doors 2 and 3 are opened, this roller 87 moves as the hinge 1 moves in the W direction.
While the spring 86 is being compressed, the guide frame 8
3, the roller frame 84 is lowered, and the roller 87 moves from the solid line to the imaginary line through the dashed-dotted line while slidingly contacting the lower surface of the rail 5a.

Further, when closing from opening, the roller 87 moves in the Y direction (opposite to the W direction), returns from the imaginary line through the dashed line to the solid line position, and the roller 87 is locked to the guide rail 5. be done.

According to the above embodiment, an average closed state can be obtained by the latch member 8 and the runner, and the pair of support pieces 14, 14 are connected to the fixing plate 8 of the latch member 8.
0,81, so the side plates 11,1 of hinge 1
1 opening can be reinforced.
Furthermore, since there is only one roller 87, locking and unlocking can be performed accurately.

In addition, the guide frame 83 and the roller frame 84
Since they are mounted in a prismatic shape, there is no need to prevent them from rotating, and the structure is simplified.

Furthermore, in the hinge 1 of the above embodiment, since the side plates 11, 11 are in surface contact with the mounting plate 16 in the vertical direction, contact is maintained over substantially the entire area of the end surfaces 2a, 3a, and the shaft There is no generation of external force that is inconvenient for the fitting between the portion 12 and the bearing 15. Therefore, the rotation structure between the shaft portion 12 and the bearing 15 does not cause rattling, and the connection of the foldable door has durability.

Furthermore, the same effect can be obtained even if the latch member 8 holds the curtain plate 10 of the hinge 1 as a plate-like piece.

It goes without saying that the structure of the folding door is not limited to the embodiment.

[Effects of the invention] As explained above, the invention provides the following effects.

If the fixing plate is inserted from above into the space between the side plates of the hinge, the plate-like piece will be held between the pair of fixing plates, and it can be fixed with screws from the U-shaped opening in the horizontal direction of the hinge. It is very easy to assemble and can be used regardless of the hinge structure as long as there is a plate-like piece.

Further, since it can be fixed from the lateral direction, it is possible to finely adjust the mounting position while observing the state in which the latch member is locked to the guide rail.

The basic form is a pair of fixing plates that can be screwed together, and a guide frame that is U-shaped and has an elongated hole above one of them, and if a spring is interposed in this frame and a pin is inserted into the elongated hole,
Since the movable frame can be attached so as to be freely retractable, the number of parts can be reduced, and the latch member can be assembled extremely easily, making it possible to commercialize the product.
