Description

[Detailed explanation of the idea] The present invention relates to a hinge device.

The purpose of this invention is to allow the panel to be opened and closed smoothly in a watertight manner, and when the panel is fully closed, the cushioning effect of the soft material stopper cushions the shock and prevents the impact noise. The purpose of the present invention is to provide a hinge device that can securely prevent danger.

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

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

2 parallel to the center of the plane part 2 through the partition of the sacred music 19.
The strip bearings 3, 3 are recessed over the entire length in the longitudinal direction.

The bearings 3.degree. 3 are approximately semi-circular arc-shaped, and form an arc-shaped curved surface portion 4 having the same radius of curvature around each bearing 3,3.

At the center of the curved surface portion 4, there is provided a protrusion 6 that bulges outward over the entire length in the longitudinal direction and has a substantially C-shaped cross section and is notched inward.
A mounting hole 5 is bored on the inner surface.

The panel 7 is also extruded from hard synthetic resin, aluminum, etc., and is provided with an arcuate surface 15 on the negative side end surface over the entire length in the longitudinal direction for sliding along the curved surface portion 4.

A cylindrical shaft 9 in which a 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.

The shaft 9 is rotatably inserted into the bearing 3 on one side of the hinge body 1, and the arcuate surface 15 slides along the curved surface portion 4 using the bearing 3 as a fulcrum to open and close the panel 7.

A stopper 10 is provided on the other edge of the arcuate surface 15 so as to protrude over the entire length of the panel I in the longitudinal direction.

The stopper 10 is made of a soft material with good watertightness and cushioning properties, such as a soft synthetic resin material, and is co-extruded with the panel 1.

The stopper 10 is also approximately the same length as the hinge body 1 to maintain watertightness.

The stopper 10 slides in contact with the outer peripheral surface of the curved surface portion 4, and contacts the outer peripheral surface of the protrusion 6 when the panel 7 is closed to reduce the impact.

Also, the tongue piece 16 on one end edge of the panel 1 is connected to the flat part 2 of the hinge body 1.
This prevents the panel γ from opening any further.

Also, when panel I is opened, the shaft 9 of tongue piece 16 of panel 7
The mounting part contacts the seigaku 19 that partitions the bearing 3, and the panel 7
is prevented from rotating beyond a certain angle (for example, 90 degrees).

FIG. 2 shows a plate 12 used to close the side opening of the hinge body 1.
This is an embodiment in which the can be attached freely.

The plate 12 is approximately hemispherical and has two shaft holes 8°8 from the bottom surface.
Legs 13.13 that fit into the screws protrude, and a through hole 4 into which a screw 11 such as a tapping screw is inserted is bored at the top.

As an example of connecting adjacent panels 7.7 via the hinge body 1, the shaft 9 of each panel 7.7 is fitted into the bearing 3, each leg 13 of the plate 12 is inserted into the shaft hole 8, and Each panel 1 is connected to the hinge body 1 by screwing the screw 11 into the attachment hole 5 through the through hole 20.

FIG. 3 shows an example of use in which each panel I is pivoted to the hinge body 1 within a range of about 90 degrees, and a partition A is formed by combining a plurality of panels 7 and the hinge body 1, respectively.

In this embodiment, a shaft 9 and a stopper 10 are provided at the end of the panel I.
Although an example in which the shaft 8 and the stopper 10 are integrally molded is shown, it is not necessarily limited to this, and a frame having the shaft 8 and the stopper 10 may be attached to the panel 1, or the stopper 1 may be attached to the panel 1.
0 may be joined to the panel 1 as a separate body.

In the present invention, two bearings are provided in the longitudinal direction approximately in the center of the flat part of a long hinge body having a substantially semicircular cross section, and longitudinal bearings are provided on the end faces of nine adjacent panels via the hinge body. Since arcuate surfaces are provided along the curved surface portions along the direction, and shafts provided along the longitudinal direction on one side edge of the end surface of the panel are pivoted to the bearings of the hinge body, the arcuate surfaces of the panel are aligned with the curved surface of the hinge. This allows for smooth and reliable rotation around the pivot axis along the section.

A ridge protruding outward from the curved surface of the hinged body is provided along the longitudinal direction of the curved surface of the housing, and a soft material is provided on the other side edge of the end face of the panel in contact with the ridge along the longitudinal direction. Because each stopper is provided, when the panel is fully closed, the soft material stopper cushions and abuts against the protrusion, which reduces the impact between the panel stopper and the hinge body, and prevents wear and tear on the protrusion. It is possible to prevent this and also to prevent the sound of impact upon impact.

Moreover, since the stopper is made of soft material, it can prevent water from entering through the hinge attachment point even when installed in a humid location, and there is no danger of fingers getting stuck between the stopper and the protrusion. It is.

In addition, in this invention, the arc length of the above-mentioned arc shape is an abbreviation of the end face of the panel -
The length extends from one side edge to approximately the other side edge, and the arc length of the curved surface portion is approximately equal to the arc length of the arcuate surface, so when the panel is opened and closed, the arcuate surface moves along the curved surface, causing There are no gaps between the panels, and there are curved parts, which poses the risk of fingers getting caught, and because there are no gaps, the hinge body itself doubles as a material to hide the gaps. This has the effect of giving an integrated image with the finished and folded panel.
