Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a folding door comprising a main frame consisting of upper and lower horizontal X-shaped hinges and a vertical rod connecting these hinges, and a surface material attached to the surface of the main frame.

A folding door is designed to maintain a small gap between its lower edge and the floor so as not to scrape the floor when opening and closing.

However, such an arrangement is not preferable in terms of heat insulation or sound insulation.

When opening and closing such a folding door, the present invention maintains an appropriate gap between it and the floor like conventional folding doors, but when the door is closed (
Insulating the folding door by automatically sealing the gap between its lower edge and the floor surface.

This is an attempt to improve the sound insulation effect.

The sealing device according to the present invention is applied to a folding door comprising a surface material attached to the surface of a main frame consisting of upper and lower horizontal X-shaped hinges and a vertical rod connecting these hinges. A hinge is provided vertically on the top of the folding door, and a sealing material is suspended from the upper pivot of the upper vertical hinge to seal the gap between the lower edge of the folding door and the floor surface when the vertical hinge is extended. .

The invention will now be described in connection with various embodiments of the invention shown in one drawing.

Figures 1, 2, and 3 show an embodiment of the present invention, and in Figure 1, 1 indicates a horizontal X-shaped hinge, and 2 indicates a rod connecting the upper and lower horizontal X-shaped hinges. The rod constitutes a main frame, and the folding boot 2a is formed by attaching the surface material 3 to the main frame.

A large number of removable rods 4 are provided to connect the rods 2 on both sides of this main frame.

A vertical hinge 5 connecting a pair of adjacent removable rods 4 is attached so as to bend upward in a vertical plane.

A sealing material 7 is suspended from the upper pivot 6 of the vertical hinge.

In this embodiment, when the folding door is in the closed position, the vertical hinge 5 is extended, its pivot 6 is lowered, and the sealing material 7 is lowered accordingly to seal the gap between the folding door and the floor surface. .

The embodiment of FIG. 4 is substantially similar to that shown in FIG. 1, but shows an arrangement in which the vertical hinge 5 is attached to the central pivot of the horizontal X-shaped hinge 1 of the main frame. As shown in Figure 1, the horizontal X-shaped hinge at the bottom of the main frame is used as a support for the vertical hinge, without requiring a separate vertical hinge support using a removable rod, resulting in a simple structure. ,
The cost is also low.

The embodiment of FIGS. 5 and 6 shows a structure in which a pair of sealing members are provided, a vertical X-shaped line 51 is provided in the main frame, and the movement is slidably attached to the rod 2 of the main frame. An operating link 8 is connected between the frame 9 and the upper pivot 60 of the vertical X-shaped hinge 5, and a sealing material 71 is attached to the moving frame 9.

As shown in FIG. 7, the vertical
Supported.

In this embodiment, as shown in FIG. 6, in the open position of the folding door, the moving frame 9 is pulled up by the vertical X-shaped hinge 5, while in the closed position, the vertical X-shaped hinge extends and Because axis 6 descends,
Lower the moving frame to the position of 9 or 9 and remove the sealing material 71? It descends to the position shown at 2Vc and seals the gap between it and the floor.

As mentioned above, the present invention can be implemented in various ways, but
When the folding door is closed, the sealing material protrudes downward to seal the gap between the folding door and the floor, significantly improving sound insulation and heat insulation effects.
