Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a folding gate in which a plurality of door bodies are connected in the left-right direction.

This type of gate is widely used because the door body can be compressed into a compact state, the structure is simple, and it is suitable for mass production.

However, in conventionally known folding gates, each door body is only 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, so it is difficult to open and close the door body. It cannot be said that the condition is necessarily satisfactory, with the door body bending irregularly and sometimes creeping out onto the road.

In view of these circumstances, the inventors of the present invention have made extensive studies to make the door body stably self-supporting and to smoothly open and close the door body. In a gate that can be freely folded in a zigzag shape by hinged side parts of adjacent door bodies 1 and 1, a hinge that significantly protrudes outward from the upper end of the mounting board 2 in the front-back direction and the left-right direction of the door body. 3
and a hinge piece 5 having a hinge 4 whose direction in the front-back direction is opposite to that of the hinge 3 and slightly protruding outward in the front-rear direction and left-right direction of the door body from the lower end of the mounting board 2'; and from the lower end of the mounting board 2' A hinge 3' that protrudes largely outward in the front-rear direction and left-right direction of the door body, and a hinge 3' that is opposite to the hinge 3' from the upper end of the mounting board and that is small outward in the front-rear direction and left-right direction of the door body. A hinge piece 5' having a protruding hinge 4' is arranged such that the shaft holes of the hinge pieces 5, 5', which have a small protrusion, are concentric, and the hinge pieces 5, 5' have a large protrusion. The axial holes of the hinges 3, 3' that have been extended are placed in symmetrical positions with the axial holes of the hinges 4, 4' that have been slightly protruded, and the axial holes of the hinge that have been made to protrude greatly on one side and the axial holes of the other hinge. The mounting board 2 of each of the hinge pieces 5, 5' is mounted using hinge fittings 7, 7, which are pivotally connected by disposing links 6, 6 between the small protruding shaft holes of the hinge pieces, respectively. , 2' are the adjacent door bodies 1, 1
By fixing it to the side edge of the door, the stability and operability of the door body are dramatically improved.

The folding gate shown in Figures 1 to 3 is
The hinge fittings 7, 7... are provided at the side ends of the adjacent door bodies 1, 1... alternately in opposite directions so that they can be bent in a zigzag pattern, and the hinges 7, 7... are provided at the side ends of the main door bodies 1, 1... so that they can be bent in a zigzag shape. Auxiliary gate bodies 1', 1' consisting of about half the width of the body are provided, guide rollers 8, 8... are rotatably attached to the central lower end of the main door bodies 1, 1..., and these are laid between the gate posts. It is engaged with the rail 9, and the fourth
In the case shown in the figures to FIG.
The auxiliary door An auxiliary connecting rod 1 having a length approximately half of the connecting rod 10 is placed at a lower outer position of the bodies 1', 1'.
0', 10' are pivotally supported, and adjacent connecting rods 10, 1
0... and the ends of the connecting rod 10 and the auxiliary connecting rod 10' are rotatably connected with pins.

In carrying out the present invention, in order to prevent excessive movement of the respective hinge fittings 7, 7..., a protrusion serving as a stopper is provided on the outer surface of the mounting base plate 2, 2' of each hinge piece 5, 5'. 11, 11 should be formed, and when connecting rods 10, 10... and auxiliary connecting rods 10', 10' which intersect in a pantograph shape are provided on the door bodies 1, 1... and the auxiliary door bodies 1', 1'. In this case, the laying rail can be omitted by using casters instead of guide rollers.

The present invention has the above-mentioned configuration, and the hinge piece 5, which has a hinge 3 that protrudes largely in opposite directions at the upper and lower positions of the mounting board 2 and a hinge 4 that protrudes slightly in opposite directions, and a hinge piece 5 that is opposite to each other at the upper and lower positions of the mounting board 2'. The hinge pieces 5' are combined in a pair, forming a hinge 4' that projects slightly in the direction of the arrow and a hinge 3' that projects greatly, and one hinge piece has a large protruding hinge and the other hinge piece has a small protruding part. A hinge fitting 7 which is pivotally connected by disposing links 6, 6 between the hinges,
7 connects the side ends of the door bodies 1, 1... and the auxiliary gate bodies 1', 1', so that the adjacent door bodies can be integrally connected to the mounting boards 2, 2' of both hinge pieces 5, 5'. The hinges 3, 3' that protrude significantly and the hinges 4, 4' that protrude small integrally from the same mounting board are pivotally connected in an overlapping state by links 6, 6 to form the door body. It can be suspended in a predetermined position with a strong supporting force, and the installed gate does not wobble and has excellent self-sustaining stability, and when opening and closing it, it is possible to , When starting to extend the folded door bodies 1, 1, the hinge pieces 5, fixed to the side edges of the door bodies 1, 1...
There is a large V-shaped opening between the hinges 3, 3', which protrude more than the mounting boards 2, 2', centering on the shaft holes of the hinges 4, 4', which protrude smaller than the mounting boards 2, 2' of 5'. The legs of the links 6, 6 rotate inward, causing mutual bending of the door body, and after both links 6, 6 reach the same vertical plane, the other large protrusion in the same vertical plane The links 6, 6 rotate around the shaft holes of the hinges 3, 3' that have been made to protrude, and at the end of the rotation, the links 6, 6 rotate around the shaft holes of the hinges 3, 3' that have been made to protrude greatly. The legs are opened in a V-shape, and when the extended door body is folded, the operation in reverse to the above is repeated, and whether the door body is retracted or opened. Since the links 6, 6, which are opened in a V-shape, are rotated inward, the stationary gate can be operated with a small amount of force by applying force in the left and right direction to the moving side of the gate. In combination with the fact that the door body does not wobble, the door body can be opened and closed extremely smoothly.
