Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a folding door in which a plurality of door body units are successively pivotally connected in the left-right direction, and is suitable for a gate 1 partition door or the like.

In this Yuzu folding door, each door body unit is simply connected by the tA number consisting of two blade plates or the current hanging bracket, and the bonding strength between the outside of the door is poor, causing the door body to sway laterally. However, when opening and closing, the door body bends irregularly and sometimes extends onto the road, so it cannot be said that the rattan is in a satisfactory condition.

The inventors of the present invention have worked diligently to develop a method for smoothly opening and closing a folding door in which each door unit can have a V-plane shape 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 of repeated consideration, several door body units σ)
When connecting α)... in the left-right direction, a hinge piece (4) formed with a spindle part ■ that protrudes largely in opposite directions at the top and bottom positions and a spindle part C3) that protrudes small. The hinge pieces ml, which form part e) of the supporting shaft part that projects slightly in opposite directions in the vertical position and the supporting shaft part that projects largely, are combined in a pair, and one support part of the hinge piece is made to protrude greatly. A hinge metal fitting in which a link 6) 6) is arranged in a V-shape between the shaft portion and a small protruding support shaft portion of the other hinge piece and is rotatably fixed.
was used to sequentially change the direction of the hinge metal fittings back and forth to connect each door body unit α) α)... to form a door body unit α)(1)... Space department...

(1) A hinge fitting that attaches 111 σ) (the intended purpose is achieved by hinged in the opposite direction of θ).In carrying out the present invention, the main door unit σ) On both sides of G)...and the surface grid body ■8)..., there are auxiliary door units σ)α) each consisting of approximately half the width.
and an auxiliary surface grid body 85 el tt are provided, and guide rollers are provided at the central lower end of the door unit α) α) and at the outer lower end of the moving side auxiliary door unit ω at appropriate positions. f! It is pivoted so that it can move freely, and this is connected to the support (10) and the laying rail (11) installed between the rails.

In order to avoid contact at the ends of

Claims (1)

[Claims] When connecting several door units in the left-right direction, a hinge piece is formed with a support shaft portion that protrudes largely in opposite directions at the top and bottom positions and a support shaft portion that protrudes small. The first pieces are combined in a pair, forming a spindle portion that protrudes small and a spindle portion that protrudes greatly in opposite directions at the top and bottom positions, and the spindle portion that protrudes greatly on one hinge piece and the spindle portion that protrudes greatly on the other hinge piece. Each door body unit is assembled by using a hinge member which is rotatably fixed with links arranged in a V-shape between small protruding support shafts, and the direction of the hinge member is sequentially changed back and forth. connected, and suspending the screen grid body in a space formed in the door unit so as to be rotatable about the left and right intermediate position of the door unit,
A folding door characterized in that the ends of the double-sided lattice body that are in contact with each other are hinged in the opposite direction from the front to the rear using the same hinge metal fittings as described above to hinge the hinge metal fittings that hinge both door body units at the relevant position. 2-
