Description

[Detailed description of the invention] The present invention consists of a pair of panel frames 3, 3, each consisting of a vertical stile 1 and a horizontal stile 2, both made of synthetic resin, and a pair of panel frames 3.3, which are made of synthetic resin.
A metal hinge body 4 is foldably connected over the entire length of the upper and lower sides of the hinge body 4, and the hinge body 4 is foldably connected to the vertical stile 1 to prevent vertical displacement between the hinge body 4 and the vertical stile 1. A pull-out stopper 5 is fixed to both the upper and lower ends of the vertical stile 1 to lock both the upper and lower ends of the vertical stile 1, and a metal cover is coated over the entire length of the horizontal stile 2 with one end overlapping the end face of the pull-out stopper 5. This relates to a folding door comprising a cover 6.

This invention relates to a folding door that uses synthetic resin for the vertical and horizontal stile, molds the hinge body from metal, and is placed in the door frame. To provide a folding door which can minimize distortion caused by a difference in expansion/contraction rate from appearing on the outer surface and can prevent a large gap from forming between the door frame and the door frame.

In general, for folding doors in which the vertical and horizontal frames are made of synthetic resin and connected by a metal hinge over the entire length of the vertical frame, due to the difference in expansion and contraction ratio between the synthetic resin and the metal,
In particular, when this folding door is installed in an environment with large temperature changes such as a bathroom, there will be a dimensional change in the vertical stile where there is a large difference in expansion and contraction ratio, and when it shrinks, the upper and lower ends of the panel frame and the door frame will change. There is a large gap between them, which has the disadvantage of causing moisture leakage when used in a bathroom.

The present invention has been devised in view of the above points, and will be described in detail below based on the embodiments shown in the figures.

In this embodiment, the folding door is a bifold door housed in a rectangular door frame 8 made of aluminum, and this folding door has a panel frame 3 with a plastic glass plate 9 made of synthetic resin such as styrene. It is constructed by connecting a pair of door panels to and io that are fitted together by a hinge body 4.

The panel frame 3 is framed in a vertically long rectangular shape by vertical frames 1 and horizontal frames 2, both of which are obtained by extrusion molding of synthetic resin such as vinyl chloride. A door panel 10 is formed by fitting glass plates 9 above and below.

The vertical stile 1 and the horizontal stile 2 are joined by inserting the vertical piece 15 and the horizontal piece 16 of the corner block 14, which are molded into a general shape from synthetic resin, into the vertical stile 1 and the horizontal stile 2, respectively, and each door panel A pivot shaft 20 that is urged downward via a spring (not shown) protrudes from the corner block 14 located at the outer lower end of the door panel 10, and the pivot shaft 20 of one door panel 10 is connected to the lower rail of the door frame 8. 22, and the pivot shaft 20 of the other door panel 10 is engaged with the rail groove 24 of the lower rail 22 so as to be freely movable.

On the other hand, on the upper rail 23 of the door frame 8, a runner 27 with rollers 26 supported at both ends of a horizontal shaft 25 is engaged and held so as to be freely movable, and a runner shaft 28 protrudes below the lower rail 22 from the horizontal shaft 25. can be attached to and detached from the corner block 14 at the upper outer end of each door panel 10, and one runner 27 is attached to the upper rail 2 by a stopper (not shown).
The folding door is opened and closed by holding it rotatably at a fixed position 3 and running the other runner 27 within the upper rail 23, and when it is attached to the door frame 8, the folding door is folded. First, the lower pivot shaft 20 is housed in the lower rail 22, and then the runner shaft 28 is fitted into the corner block 14 through the opening 29 on the outer end surface of the horizontal stile 2.

The hinge body 4 is formed into a hollow body with a substantially semicircular cross section by extrusion of aluminum, and two bearings 31 and 31 parallel to the core of the plane portion 30 are recessed over the entire length in the longitudinal direction. .

This bearing 31 forms a semicircular groove, and curved surface portions 3 with the same radius of curvature are formed on both sides of the hinge body 4 around each bearing 31.

A cylindrical shaft 3B having a shaft hole 37 at the tip is molded over the entire length in the longitudinal direction, and the shaft 38 is connected to one of the bearings 3 of the hinge body 4.
1, and the arcuate surface 35 slides along the curved surface portion 32 using the shaft 38 as a fulcrum to open and close the door panel 10.10.

Further, at the other end edge of the arcuate surface 35, a contact portion 39 having an arcuate cross section is provided over the entire length in the longitudinal direction. This prevents the door panel 10 from opening.

Further, a part of the contact portion 39 protrudes to the side of the arcuate surface 35, and when the door panel 10 is closed, the contact portion 39 engages with a protrusion 40 that protrudes laterally from the flat portion 30 and at the same time (rolls). One of the bifurcated protrusions 43 at both ends of the wall strip 42 that partitions both bearings 31 and 31 comes into contact with the recess 41 formed along the entire longitudinal length of the outer surface of the base of In addition to preventing the door panel 10 from being
This prevents overflow.

The removal stopper 5 is formed into a substantially semicircular shape that is one size larger than the hinge body 4 in order to close the openings at both the upper and lower ends of the hinge body 4, and is
The leg 45.45 of the book protrudes, and a through hole 47 into which a screw 46 such as a tapping screw is inserted is inserted near both legs 45.45.
is bored, and a convex portion 48 projecting outward is formed at the top.

When connecting the two door panels 10.10 via the hinge body 4, the shaft 38 of each vertical stile 1 is loosely fitted into the bearing 31,
Each leg 45 of the removal stopper 5 is inserted into the shaft hole 37, and a screw 49 is screwed into the mounting hole 34 through the through hole 47 to connect the door panel 10 via the hinge body 4.
A notch 50 having approximately the same height as the removal stopper 5 is provided at both upper and lower ends of the vertical stile 1 to which the vertical stile 1 is attached.
The removal stopper 5 fits within the 0, and both upper and lower end surfaces of the removal stopper 5 are aligned approximately with the upper and lower end surfaces of the horizontal stile 2.

On the end faces of the upper and lower side frames 2, 2 facing the door frame 8, a cover 6 having a substantially U-shaped cross section obtained by extrusion molding of aluminum is attached over the entire length in the longitudinal direction, Rain hanging piece 52 at one end of the cover 6 located on the side of the hinge body 4
．． 52, the hanging piece 52 located on the side of the plane part 30 of the hinge body 4 is cut out, and the remaining horizontal piece 53 is removed and slidably placed on the peripheral wall 49 rising from the periphery of the stopper 5, and the cover 6 is attached. The horizontal stile 2 is fixed at an appropriate position with the heavies 65, and the rain hanging pieces 52 of the cover 6 cover both front and rear edges of the horizontal stile 2 over the entire length in the longitudinal direction.

A horizontal piece 53 projects from the other end of the cover 6, and a long hole 54 with one end open is provided in the horizontal piece 53, and the runner shaft 28 is fitted into this long hole 54 from the side. It becomes.

In addition, at the outer end of the vertical stile 1 on the opposite side from the hinge body 4, a side cover 55 having a substantially C-shaped cross section and made of extruded aluminum has a locking piece 56 projecting inward from the edge of the side cover 55. The runner shaft 28 is fitted into locking grooves 57 provided on both the front and rear sides of the side cover 55 and is attached over the entire longitudinal length of the vertical stile 1, and the runner shaft 28 is inserted into and removed from the window 58 provided at the upper end of the side cover 55. Thus, the cover 6 and the side cover 55 are continuous at the corner.

Here, from the side stile 2 near the hinge body 4 of one door panel 10, a latch 60 attached to the internal corner block 14 projects upward through an opening 61 of the cover 6, and when the door panel 10 is closed, this latch 60 is attached to the inner corner block 14. Upper rail 23

As described above, the present invention connects vertical frames made of synthetic resin over their entire longitudinal length with metal hinges, and also attaches covers made of metal to horizontal frames made of synthetic resin over their entire length in the longitudinal direction. One end of the stile is overlapped with the pull-out stopper fixed to both the top and bottom ends of the stile, so the stile, which tends to deform more due to the difference in the expansion and contraction rates of synthetic resin and metal, will shrink more than the hinge body. Even if the horizontal stile shrinks vertically,
One end of the cover is restrained by a stopper on the hinge body, and the cover stays in place, concealing the shrinkage of the side stile within the cover and keeping the vertical dimensions constant. This has the advantage of preventing large gaps from forming between the frame and the frame.
