Description

[Detailed description of the invention] The present invention has a cylindrical shaft 9 protruding from one side end of a synthetic resin panel 7 in the vertical direction, and a cylindrical shaft 9 extending longitudinally along the hinge body 1 at the same height as the panel 7. Bearing 3 whose two threads have a roughly semicircular cross section
. Hard cylindrical body washers 11°11 are inserted into the holes 8, 8, respectively, and two shaft legs 15 protrude from each plate 14 fixed to both upper and lower end surfaces of the hinge body 1.
, 15 are loosely fitted into the cylindrical body washers 11 at both the upper and lower ends of each cylindrical shaft 9, and each cylindrical body washer 11 comes into sliding contact along the surface of the plate 14 as the cylindrical shaft 9 rotates within the bearing 3. This relates to a folding door device.

The purpose of the present invention is to provide an easy-to-assemble folding door device that prevents abrasion of the shaft portion of a synthetic resin panel and allows smooth opening and closing over a long period of time.

The present invention will be explained in detail below with reference to the accompanying drawings.

The hinge body 1 is extruded and molded from synthetic resin, aluminum, etc., and has a substantially semicircular cross section consisting of a flat part 2 and a curved part 4, and is a long piece having approximately the same length as the panel 7. It is.

2 parallel to the center of the plane part 2 with a partition of the wall strip 19 interposed therebetween.
The strip bearings 3, 3 are recessed over the entire length in the longitudinal direction.

The bearings 3, 3 have a substantially semi-circular arc shape, and form an arc-shaped curved surface portion 4 with the same radius of curvature around each bearing 3, 3.

At the center of the curved surface part 4, a protrusion 6 having a substantially C-shaped cross section is provided extending outwardly over the entire length in the longitudinal direction and notched inwardly, and a mounting hole 5 is provided on the inner surface.

The panel 7 is a hollow panel formed by extruding synthetic resin such as polyvinyl chloride, and has the curved surface 4 on one end surface.
An arcuate surface 15 for sliding along the entire length in the longitudinal direction is provided.

A cylindrical shaft 9 in which a cylindrical shaft hole 8 is bored at the tip of a tongue piece 16 extending laterally from one end edge of the arcuate surface 15 is provided over the entire length in the longitudinal direction.

Note that it is sufficient that at least the end portion is a cylindrical body.

The cylindrical shaft 9 is rotatably inserted into one bearing 3 of the hinge body 1, and the arcuate surface 15 is connected to the curved surface portion 4 with the bearing 3 as a fulcrum.
The panel 7 is opened and closed by sliding along the panel 7.

On the other end edge of the arcuate surface 15, there are provided sills 1 to flange 10 having a bow-shaped cross section projecting over the entire length of the panel 7 in the longitudinal direction. It comes into contact with the surface and prevents the panel 7 from opening any further.

A portion of the stopper 10 protrudes toward the arcuate surface 15, and when the panel 7 is closed, the stopper 10 engages with a protrusion 17 that protrudes laterally from the flat surface 2, and is formed on the outer surface of the shaft 9. The rib 18 comes into contact with a wall strip 19 that partitions both bearings 3, and prevents the panel 7 from rotating beyond a certain angle (for example, 90 degrees) and prevents the panel 7 from coming out from the hinge body 1. .

Cylindrical body washers 11 are respectively inserted into the cylinder shaft holes 8 of the cylindrical shaft 9. The two cylinder body washers 11 are made of metal with good wear resistance, and have a flat washer portion 12 and teeth protruding from the inner circumferential lower surface. It is formed from a shaped portion 13.

When the toothed portion 13 is provided in a protruding manner, it can be inserted and fixed by biting into the cylinder shaft hole 8.

The plate 14 is formed into a substantially semi-disc shape in order to close the openings on both upper and lower ends in the longitudinal direction of the hinge body 1, and has two shaft legs 15 and 15 protruding from the lower surface, and a tapping screw-like screw on the top. A through hole 20 is bored through which the fastener 21 passes.

In order to connect adjacent panels 7.7 with the hinge body 1 as shown in FIG. 3, the cylindrical shaft 9 of each panel 7.
.
1, and fit the shaft legs 15.15 of the plate 14 into the cylinder washer 11.11, respectively, and insert the fastener 21 into the mounting hole 5 through the through hole 20. It is screwed in and fixed to both the upper and lower end surfaces of the hinge body 1 in the longitudinal direction.

In the above embodiment, the hinge body 1 having a substantially semicircular cross section has been described, but the present invention is not limited to this hinge body 1.

In the present invention, as described above, a cylindrical shaft is provided vertically extending from one side end of a synthetic resin panel, and a cylindrical shaft is provided along the longitudinal direction approximately in the center of the flat part of the hinge body at the same height as the panel. Two bearings each having a semicircular cross section were installed, and the cylindrical shafts of the adjacent panels were fitted into the bearings of the hinge body, so all that was needed was to fit the cylindrical shafts of the panels into the bearings of the hinge body, respectively. To obtain a door device which can be assembled with a cylindrical shaft, has a large contact area between a cylindrical shaft and a bearing, has a small withstand pressure load, has little wear, has good durability, and can be folded smoothly.

In addition, hard cylindrical body washers are inserted into the cylindrical shaft holes on both the upper and lower end surfaces of the cylindrical shaft, and two shaft legs protruding from each plate fixed to the upper and lower end surfaces of the hinge are attached to the upper and lower ends of each cylindrical shaft. It fits loosely into the cylindrical body washers at both ends, and each cylindrical body washer slides along the surface of each plate as the cylindrical shaft rotates within the bearing.
The shaft legs of each plate are loosely fitted to both the upper and lower ends of the cylindrical shaft of the panel that is housed in the bearing of the hinge body, so that the cylindrical shaft rotates within the bearing around the shaft legs at both the upper and lower ends. As a result, each shaft leg can prevent the cylindrical shaft from rotating within the bearing, and as a result of fixing plates with shaft legs to the top and bottom of the hinge body to prevent this rotational vibration, the plate Both the upper and lower end surfaces of each cylindrical shaft that come into sliding contact with the cylindrical shaft are covered with hard cylindrical washers to prevent wear on the upper and lower end surfaces of the cylindrical shaft, allowing the panel to rotate smoothly over a long period of time. It is possible.
