JPS5916633B2 - Folding door with return prevention device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a handle 2 having a width approximately equal to the width of the folding door 1 when folded, protruding in the folding direction at one end of the folding door 1. This invention relates to a folding door with a return prevention device characterized in that a magnet 4 is provided at the protruding end of the handle 2 and can be freely attracted to a pillar-like vertical frame 3 formed of a magnetic material on the other end. The purpose is to provide a folding door with a return prevention device that prevents the folding door from returning when folded.

When conventional folding doors are folded, the repulsive forces of the exterior material and hinges cause the folding doors to return to a slightly wider direction, leaving them in a half-open state, narrowing the opening and narrowing the passageway.

The present invention has been made in view of this point, and will be explained in detail below using Examples.

FIG. 1 shows an example in which a slutter door is used as the folding door 1. The folding door 1 connects a number of panels 5 in a foldable manner and has end pieces 5a at both ends.

6b is provided and formed.

One end piece 6b is fixed to the vertical frame 3 of one of the pillars of the opening between the rooms in the room.

A handle 2 is attached to the other end piece 6a in a horizontal position, and the width of the handle 2 in the horizontal direction is approximately the same as the width of the folding door 1 when folded. A magnet 4 is attached to the end.

The opening can be opened and closed by moving the end piece 6a on the movable side, and when the folding door 1 is folded, the magnet 4 of the pusher 2 is attracted to the vertical frame 3 made of a magnetic material such as iron. It is maintained in this state.

If a magnet 4' is also attached to the end of the pusher 2 on the movable side, it is possible to prevent the folding door 1 from returning when it is extended.

Next, FIG. 2 shows an example in which an accordion door is used as the folding door 1, and the folding door 1 has an end piece 6.
The exterior material between ay5b can be folded into a bellows shape, and a magnet 4 as shown in FIG. 3a is provided at the end of the handle 2 attached to one end piece 6a and the other end piece 6b A magnet 4' as shown in FIG. 3 is provided at the other end.

The handle 2 can be of various designs such as the one shown in Fig. 1, the one formed into a hollow ring as shown in Fig. 2, and the ones a, b, c, and d shown in Fig. 4.

As described above, in the present invention, a handle is provided at one end of the folding door protruding in the folding direction, and a magnet that can be freely attracted to a vertical frame made of a magnetic material at the other end of the folding door is provided. is installed on the handle, so when the folding door is folded, the magnet on the handle is attracted to the vertical frame, and the repulsive force of the exterior material and frame due to the impact when folding is applied in the direction of the folding door spreading. There is an advantage that the force can be absorbed by this suction force and there is no fear that the folding door will return to its original state, and that when the folding door is folded, the suction force of the magnet can prevent the folding door from swinging and hold it vertically.

Moreover, since the handle is formed to have approximately the same dimensions as the folding door, the handle can cover the sides of the folding door when folded, which has the advantage of reducing the chance of contact with other objects and preventing dirt.

[Brief explanation of the drawing]

Fig. 1 is a top sectional view of one embodiment of the present invention, Fig. 2 is a front view of another embodiment of the same as above, Fig. 3a is a right side view of Fig. 2, and Fig. 3 is a view of Fig. The left side view and FIG. 3C are cross-sectional views taken along the line A-A in FIG. 2, and FIGS. is a magnet.

Claims (1)

[Claims] 1 A handle with a width approximately equal to the width of the folding door when folded is provided at one end of the folding door and protrudes in the folding direction, and a pillar formed of a magnetic material is provided at the other end of the folding door. A folding door with a return prevention device characterized in that a magnet that can be freely attracted to a vertical frame such as the above is provided at the protruding end of the handle.
