Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a folding door in which a plurality of door body units are sequentially pivotally connected in the left and right direction.
It is suitable for gates, partition doors, etc.

In this type of folding door, each door body unit is simply connected by a hinge made of two blades or a ring-shaped hanging metal fitting, and the bonding strength between the door bodies is poor, causing the door body to sway laterally. However, when opening and closing the door, the door body bends irregularly and sometimes creeps out onto the road, so it cannot be said that the condition is necessarily satisfactory.

The inventors of the present invention have conducted extensive studies on a method for smoothly opening and closing a folding door in which each door unit can be made flat when the door is unfolded, by preventing the door from swinging laterally and allowing the door to stand on its own in a stable manner. As a result, when connecting the plurality of door unit units 1, 1... in the left-right direction, a support shaft part 2 that protrudes largely in opposite directions at the top and bottom positions and a support shaft part 3 that projects slightly are formed. The hinge pieces 4 are combined in a pair with a hinge piece 4' forming a support shaft part 3' which is slightly protruded in opposite directions at the top and bottom positions, and a support shaft part 2' which is largely protruded, and one of the hinge pieces is made to protrude greatly. Using hinge fittings 6, 6 which are rotatably fixed with links 5, 5 disposed in a V-shape between the pivot shaft of the hinge piece and the slightly protruding pivot of the other hinge piece, the hinge Each door body unit 1, 1... is connected by sequentially changing the direction of the metal fittings back and forth, and the surface grid bodies 8, 8... are connected to the spaces 7, 7... formed in the door body units 1, 1...
is suspended rotatably around the middle position between the left and right sides of the door body unit, and the ends of the adjacent double-sided lattice bodies 8, 8 are connected using the same hinge metal fittings 6 as described above, and both the door body units 1, 1 at the relevant position are suspended. The intended purpose was achieved by hinged the hinge metal fitting 6 in the front and back directions. In carrying out the present invention, auxiliary door units 1', 1' and auxiliary surface lattices each having a width of approximately half are provided on both sides of the main door units 1, 1, . . . guide rollers 9, 9 are provided at the central lower end of the door units 1, 1... and at the outer lower end of the movable side auxiliary door unit 1' at appropriate positions.
... is rotatably attached to the shaft, and this is attached to the pillars 10, 10.
The door body units 1, 1... are engaged with the laying rail 11 provided between them, and the door body units 1, 1 when the door body is opened flatly.
In order to avoid contact between the vertical frame and the ends of the screen grids 8, 8..., there is a U-shaped space between the hinge pieces 4, 4' of the hinge fitting 6 and the screen grids 8, 8, as shown in the figure. Either the fitting pieces 12, 12 should be interposed, or the vertical frame of the door unit at the relevant position should be bent outward.

In the figure, reference numeral 13 indicates a door mounting aid, and reference numeral 14 indicates a locking metal fitting.

The present invention has the above-mentioned configuration, and when connecting the plurality of door units 1, 1... in the left-right direction, the support shaft part 2 is made to protrude greatly in opposite directions at the top and bottom positions, and the support shaft part 2 is made to protrude small. A hinge piece 4 forming a support shaft part 3, a hinge piece 4' forming a support shaft part 3' projecting small in opposite directions at the top and bottom positions, and a support shaft part 2' projecting largely are combined in a pair. Links 5, 5 are provided between the largely protruding support shaft of one hinge piece and the small protruding support shaft of the other hinge piece, respectively.
Using hinge metal fittings 6, 6, which are arranged in a V-shape and rotatably fixed, the orientation of the hinge metal fittings is sequentially changed back and forth to form each door body unit 1, 1...
are connected, and the screen grid bodies 8, 8... are suspended in the spaces formed in the door units 1, 1... so as to be rotatable about the left and right intermediate positions of the door units, and the adjacent double-sided grids are The ends of the bodies 8, 8 are hinged using the same hinge fittings 6 as described above, with the front and back directions reversed to the hinge fittings 6 that hinge the both door body units 1, 1 at the relevant positions, so that they can be opened and closed. In this case, as shown in FIGS. 5 to 8, the small protruding parts of the hinge fittings 6, 6... hinged on the side edges of the door units 1, 1... and the screen grid bodies 8, 8... The link 5 has wide-angled legs between the support shaft parts 2 and 2' that are largely protruded around the support shaft parts 3 and 3' that are
5 rotates inward to cause mutual bending of the door units 1, 1 and the screen grid bodies 8, 8, and after both links 5, 5 in the hinge fittings 6, 6 intersect in a straight line, Links 5, 5 centered on the other small protruding support shaft 3, 3' in the same perpendicular line
rotation occurs, and at the end of the rotation, the links 5, 5 are opened in a V-shape around the support shafts 3, 3', and therefore the door units 1, 1... and the surface grid body are opened. 8, 8... can be folded extremely compactly by overlapping in the front and back direction when the door body is retracted, and when the door body is opened, the door body units 1, 1... and the surface grid body 8 , 8... can be overlapped in the left and right direction to form a planar door body, while the fulcrum of the hinge fittings 6, 6... protrudes in the front and back direction, and the links 5, 5...... V
Since it rotates inward with its legs spread apart,
The door body can be moved with a small amount of force.

According to the present invention, the screen grid bodies 8, 8... are interposed between the door units 1, 1... at intermediate positions of the door bodies, and these are intersected with the door units 1, 1... in a pantograph shape. Since the movement of the door units 1, 1... can be controlled by the movement of the door units 8, 8...
This prevents the door body from swinging sideways or irregularly bending, allowing extremely smooth opening and closing operations.

Furthermore, according to the present invention, the door body units 1, 1...
The hinge fittings 6, 6... that hinge the surface grid bodies 8, 8... have a structure in which links 5, 5 are interposed between the support shafts at both end positions of the hinge pieces 4, 4'. By connecting the door body unit and the screen grid body extremely strongly, and by arranging the screen grid bodies 8, 8, etc. in the space of the door unit 1, 1, etc., a novel and aesthetically pleasing door body can be formed. It is something.
