Description

[Detailed description of the invention] This invention relates to a folding door that is hung over the front opening of a storage unit such as a closet or cupboard and opens and closes the front opening to widen the opening. Fixtures such as runners are hidden behind the folding panel, and the gaps between the folding panel and the frame and bottom frame of the front opening of the storage compartment are reduced to improve the appearance, and the upper part is separated from the bottom frame. Even if there is a dimensional difference in the spacing between the two, it is possible to hang it so that it can be opened and closed smoothly without vibration.

Hereinafter, the present invention will be explained based on the drawings.

The folding door shown in FIGS. 1 and 2 is an embodiment of the present invention.

An abbreviated upper rail 2 is vertically provided on the upper frame portion 1 of the inner peripheral surface of the front opening a of the storage section, and an abbreviated lower rail 4 is provided upright on the lower frame portion 3. .

Furthermore, as shown in FIG. 3, a plurality of unit panel pieces are connected by pivoting the side ends of the unit panel pieces on both sides of the band-like connecting piece 5. A suspension runner 7 that protrudes rearward and has a rolling wheel 6 at its tip is provided at the upper part of the strip-shaped connecting piece 5, and at the lower part, it protrudes rearward and slides downward against the spring force of the spring 8. A freely movable anti-shake runner 9 is provided.

The vibration prevention runner 9 includes a fixed part 10 attached to the strip-shaped connecting piece 5, and a sliding part that passes through the fixed part 10 so as to be slidable in the vertical direction, has a lower end bent rearward, and has a rotating wheel 11 at its tip. 12, and a sling 8 is interposed between the upper end of the slide portion 12 and the upper surface of the fixed portion 10.

The rolling wheel 6 of the hanging runner 7 is engaged with the upper rail 2, the rotating wheel 11 of the anti-sway runner 9 is engaged with the lower rail 4, the upper edge 13 of the folding panel b is engaged with the upper casing 1, and the lower edge 14 of the folding panel b is engaged with the upper rail 2. are respectively proximate to the lower frame portion 3 and are suspended from the folding panel b or the front opening a of the storage portion so as to be openable and closable.

Therefore, in the folding door, - the upper rail 2, the lower rail 4, the hanging runner 7, the swing prevention runner 9, and other fixtures are hidden behind the folding panel b, and the space between the folding panel b and the front surface of the storage section D The gap between the upper frame part 1 and the lower frame part 3 of a is small, and the appearance is good. Even if there is a dimensional difference in the distance between the rotating wheel 11 and the lower frame portion 3, the rotating wheel 11 can be suspended by engaging with the lower rail 4, and in this case, the rotating wheel 11 moves downward against the spring force of the spring 8. Because it engages under tension,
Since the hanging runner 7 is provided on the strip-shaped connecting piece 5, which allows the folding panel b to smoothly move without shaking and to slide linearly even when the folding panel b is folded and opened/closed, 7 slides linearly to smoothly open and close the folding panel.

In addition, in the folding door of the present invention, as in the embodiments shown in FIGS. 4 and 6, the folding panel b is suspended so as to enter into the front opening a of the storage section, and is flush with the front surface of the storage section. This is desirable in terms of appearance.

In the embodiment shown in FIG. 4, as also shown in FIG.
The anti-shake runner 9 is composed of a fixed part 10 and a sliding part 12 that passes through the fixed part 11 so as to be slidable in the vertical direction. Since the rotating wheels 11 of the vibration prevention runners 9 do not rotate relative to each other, opening and closing can be performed more smoothly, and the lower edge 14 of the folding panel b is less likely to shake. This is preferable.

Also in the embodiment shown in FIG.
is composed of a fixed part 10 and a sliding part 12, and in this embodiment, the sliding part 12 is formed into a bifurcated shape and penetrates the fixed part 10, so that the penetrating sliding contact parts of the two parts rotate relative to each other. This is preferable because the folding panel b can be opened and closed more smoothly and the lower end edge 14 of the folding panel b is less likely to swing, similar to the above embodiment.

In addition, in this embodiment, as shown in FIG. 7, protrusions 18 provided on the side edges of the panel piece 17 are rotatable in both grooves 15 of the mold material 16 having grooves 15 formed on both side edges. A bent portion 15 is formed by being fitted into the shape member 16, and a slide groove 19 is formed in the longitudinal direction of the shape member 16, and a slide groove 19 is formed in the slide groove 19 in the longitudinal direction.
Since the hanging runner 7 and the anti-shake runner 9 are slidably fitted together and fixed with screws 20,
The mounting positions of the hanging runner 7 and the vibration prevention runner 9 can be easily moved up and down.

As mentioned above, in the folding door of the present invention, the upper rail, the lower rail, the hanging runner, the anti-sway runner, and other attachments are hidden behind the folding panel, and the folding panel and the upper and lower parts of the front opening of the storage compartment are hidden behind the folding panel. The gap between the front opening of the storage compartment and the bottom frame is small, giving it a good appearance, and the anti-sway runner can slide downwards against the spring resistance, so there is no difference in the distance between the upper and lower frame parts of the front opening of the storage compartment. Even if the folding panel is folded open and closed, it can be opened and closed smoothly without wobbling, and even when the folding panel is folded open and closed, the hanging runner is provided on the strip-shaped connecting piece, which can slide in a straight line. The folding panel slides linearly and smoothly opens and closes.
