Description

[Detailed description of the invention] The present invention relates to the structure of a hinge for a folding door.A bearing fitting 3 having a bearing recess 2 with a substantially C-shaped cross section is attached to the end of a panel 1, and a A plurality of panels 1, 1... are hinged by providing protruding shaft pieces 6, 6 having tapping holes 5, and rotatably inserting these shaft pieces 6, 6 into the bearing recess 2 of the bearing tool 3. 4. Foldable and connected,
The outer diameter is larger than the outer diameter of the shaft piece 6 and the bearing recess 2
Insert the spacer cylinder 8 whose inner diameter and outer diameter are approximately the same into the bearing recess 2 of the bearing tool 3, and tap the lower part of the screw 10 rotatably inserted into the upper and lower through holes 9 of the spacer cylinder 8 to the hinge 4. This relates to a panel connection structure of a folding door which is screwed and fixed into a hole 5.

For folding doors, by rotatably inserting the shaft pieces 6, 6 on both sides of the hinge 4 into the bearing recesses 2, 2 of the bearing fittings 3, 3 attached to the ends of the panels 1, 1, the panel The following problem occurred in the case where 1 and 1 were connected to each other. That is,
As shown in FIG. 1, the opening width a of the side opening 11 of the bearing recess 2 is set to be smaller than the inner diameter b, so that the shaft piece 6 can be prevented from slipping out of the side opening 11 of the bearing recess 2. It is designed to be able to rotate within the bearing recess 2. However, in order to rotate the shaft piece 6 smoothly within the bearing recess 2, it is necessary to provide a clearance between the outer periphery of the shaft piece 6 and the inner periphery of the bearing recess 2. The diameter c is set smaller than the inner diameter b of the bearing recess 2. Therefore, due to structural errors, etc., the outer diameter c of the shaft piece 6 may become a size that approximates the opening width a of the side opening 11 of the bearing recess 2. In this case, the shaft piece 6 may close to the side surface of the bearing recess 2. Pass through the opening 11 and remove the panel 1,
There was a risk that connection 1 would come loose.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a panel connection structure for a folding door that can prevent the shaft piece from coming out of the bearing recess and eliminate the risk of the panel becoming disconnected. This is the purpose.

The present invention will be explained in detail below with reference to Examples. Panel 1
Concave grooves 13 formed on the side end surfaces of the panel 1 are provided at both ends of the panel 1.
By fitting the serrated projections 14 into the bearing member 3, the bearing member 3 is attached over the entire length of the upper and lower sides. This bearing tool 3 is provided with a bearing recess 2 having a substantially C-shaped cross section over the entire length of the upper and lower sides. The hinge 4 has a U-shaped cross section, and a shaft piece 6 having a substantially C-shaped cross section and a tapping hole 5 on the inner periphery is attached to each end of the hinge 4.
6 is protruding. A plurality of panels 1 are connected by the hinge 4 by rotatably fitting the shaft pieces 6, 6 of the hinge 4 into the bearing recess 2 of the bearing tool 3. In this case, as shown in FIG. By attaching the hinges 4 in alternately opposite directions, the panels 1, 1, . . . are connected by the hinges 4 in a foldable manner.

Here, the inner peripheral shape of the bearing recess 2 of the bearing tool 3 is formed into an elliptical shape having a major axis l and a minor axis S, as shown in FIG. Further, as shown in FIG. 6, the shaft piece 6 is cut out at the upper and lower ends of the hinge 4. Reference numeral 8 in FIG. 6 denotes a spacer cylinder made of soft or hard synthetic resin or metal, and has an oval outer circumferential shape having a major axis l and a minor axis S.
First, the shaft piece 6 is inserted into the bearing recess 2 through the opening at the upper or lower end. The outer diameter of the shaft piece 6 is formed to be slightly smaller than the short diameter S of the bearing recess 2, so that the shaft piece 6 can be freely rotated within the bearing recess 2. Next, the spacer cylinder 8 is press-fitted into the upper and lower end positions of the bearing recess 2 using the notch portion of the shaft piece 6. Since the spacer cylinder 8 does not need to be rotated within the bearing recess 2, the outer diameter can be formed to be the same as the bearing recess 2, and the spacer cylinder 8 can be formed to have the same diameter as the bearing recess 2. That's not it. Next, as shown in FIG. 4, a screw 10 is passed through the upper and lower through holes 9 of the spacer cylinder 8, and the lower end of the screw 10 is screwed into the tapping hole 5 of the shaft piece 6 and fixed as shown in FIG. In this way, the shaft piece 6
is integrated into the spacer tube 8 via the screw 10, so that the outer diameter of the shaft piece 6 matches the side opening 1 of the bearing recess 2.
Even if the width of the opening is approximately the same as the width of the opening 1, there is no risk that the shaft piece 6 will slip out of the side opening 11. Also, the screw 10 is connected to the upper and lower through holes 9 of the spacer cylinder 8.
Since the spacer cylinder 8 is press-fitted and fixed into the bearing recess 2, the shaft piece 6 is not prevented from rotating within the bearing recess 2. The outer diameter of the head 12 of the screw 10 is set to be larger than the inner diameter of the bearing recess 2, so that the head 12 of the screw 10 engages with the opening edge of the upper and lower ends of the bearing recess 2, and the shaft piece 6 It is designed to prevent it from slipping out from the upper end opening or lower end opening of the bearing recess 2.

Further, as shown in FIG. 2, guide runners 7 which are biased upwardly by a spring and are movable up and down are attached to every other hinge 4, projecting upward, and main runners 7 are attached to the upper ends of the other hinges 4. 22 is provided to protrude laterally as shown in FIG.
The guide runner 7 is inserted into the upper guide rail part 24 of the upper rail 23, and the main runner 22 is inserted into the lower guide rail part 25 of the upper rail 23. Furthermore, a door roller 26 is attached to each hinge 4 provided with a main runner 22, and this door roller 26 is inserted into a lower rail 27 as shown in FIG. When formed in this way for a folding door, the main runner 2
2. The guide runner 7 runs along the lower guide rail part 25 and the upper guide rail part 24 of the upper rail 23, and the door roller 26 runs along the lower rail 27, so that the upper and lower rails 2
When folding the folding door, the guide runner 7 comes into contact with the kick-out block 28 provided in the upper guide rail section 24 and is pushed down against the spring. Each panel 1 can be folded by protruding from inside the upper guide rail section 24 in the direction of the x arrow in FIG. Each panel 1 can be extended by pushing down the guide runner 7 on the lower surface as shown by the imaginary line in FIG. 8 and inserting the guide runner 7 into the upper guide rail section 24 again. be.

As mentioned above, in the present invention, the spacer tube prevents the shaft portion of the hinge from coming out of the side opening of the bearing recess of the bearing tool attached to the panel, which prevents the panel from being disconnected by the hinge. can be prevented.
