Description

[Detailed description of the invention] The present invention has a bottomless trapezoidal cross-section for the underframe material that supports the gate-shaped frame, and further provides an airtight material within the underframe material so that the underframe material is not transmitted from the outside. This folding door is convenient for construction because it prevents rainwater from entering the room, and also allows the frame material to be crimped to the floor to stably support the frame, and improves stability. An embodiment of the present invention will be described below with reference to the drawings.

In the figure, A is a gate-shaped frame that corresponds to the opening of the building, and a pair of formwork materials 2, 2 with a cross section of II shape are applied to the left and right ends of the upper azusa material 1 with a cross section of H shape to form a gate shape. Moreover, the upper abutment part is integrally screwed.

Reference numerals 3 and 3 denote support screws for height adjustment screwed into the lower ends of the formwork members 2 and 2 in the frame body A, which are adjustable and protrude from the lower ends of the formwork members 2 and 2 and are attached to the tips. The provided head 4 is supported by an underframe member, which will be described later, provided on a floor surface 5.

Reference numeral 6 denotes a folding door that is built into the frame A so that it can be bent freely, and a pair of vertical frames 9 and 10 are placed on both left and right ends of upper and lower frames 7 and 8 to form a rectangular door frame. The fishing head door 12 and the hand door 13, each of which has a net 11 stretched over them, are butted against each other and each is attached with a hinge 14, and the hooking door 12 is pivotally supported on one vertical frame member 2 of the frame A so that it can be expanded and bent freely. .

Reference numeral 15 designates an underframe member for supporting the gate-shaped frame body A, and has a bottomless trapezoid cross section consisting of a horizontal portion 16 and hypotenuse portions 17 and 18 on the front and rear sides thereof, and has a piece-shaped piece 19. 19 is correspondingly protruded, and a long airtight member 20 is attached to the hook-shaped piece 19, which presses against the floor surface 5.

21 is a door with a butterfly 22 attached to the outside of the opening of the building; 23 is a closing plate that shields the gap 24 formed between the folding door 6 and the underframe material 15; It is screwed so that it can be adjusted vertically.

25 is a hanging wheel for the folding door 6 that rolls the lumber 1, and 26 is a door check cover installed on the upper part of the frame A.

Although the folding door shown in the drawing is attached to the side edge of an opening in a building, it may also be attached to the door stop side of the opening.

Since the folding door according to the present invention is constructed as described above, when the frame body A is now formed and the folding door 6 is to be attached thereto so that it can be expanded and folded, first, a pair of The gate-shaped frame A is assembled by applying the formwork materials 2, 2, and the bendable folding door 6 assembled in advance is fitted into this frame A, and then the formwork materials 2, 2 in the frame A are fitted. After screwing the support screws 3, 3 onto the lower ends of 2, the underframe material 15 with the airtight material 20 attached in advance to the lower surface of the horizontal part 16 is placed on the floor surface 5, and the horizontal part of this underframe material 15 is The frame A is erected on the part 16, and its upper part is fixed to the lintel of the building, and the horizontal part 16 of the base frame material 15 is pressed and fixed by the support screws 3, 3 at the lower part, and folded with the frame A. The load of the door 6 pushes open the oblique sides 17 and 18 of the frame material 15, and the reaction force causes them to tightly engage with the support screws 3°3, and the airtight material 20 provided on the lower surface of the horizontal part 16 is pushed open to the floor. 5
This prevents the intrusion of rainwater, etc. by press-contacting the

Also, when the folding door of the present invention is installed on the doorstop side of an opening in a building, it is installed in the same manner as above.

Conventionally, as a folding door, a support screw for adjusting the height of the frame is attached to the lower end of the vertical frame of the gate-shaped frame, and this support screw is freely adjustable and supported on the base frame provided on the floor to adjust the frame. After installation, there are some cases in which at least one or more doors are hinged to each other and a folding door is inserted into the frame so that it can be bent freely. In some cases, rainwater flows into the indoor side and wets or stains the indoor floor surface, and the connection between the underframe material and the support screws of the frame is extremely unstable, making it difficult to maintain a strong structure. It was impossible to install it.

However, in the folding door according to the present invention, a pair of vertical frame members are applied to both left and right ends of the upper Azusa wood to form a gate-shaped frame on the floor surface, and an underframe is placed on the floor surface facing below the upper Azusa wood. While arranging the vertical frame members, a support screw for height adjustment is attached to the lower end of the vertical frame member of the frame body, and the support screw presses and fixes the above-mentioned underframe member. An airtight material is provided that presses against the floor surface, and at least two or more foldable doors are built inside the frame, so the gate-shaped frame can be assembled. When supporting screws are supported on the underframe material, an airtight material is attached to the horizontal lower surface of the underframe material that presses against the floor surface, so rainwater that is transmitted from the outside to the underframe material and flows into the interior of the room is prevented. Since this airtight material prevents the water from entering the room, the floor surface inside the room will not get wet or dirty during rain or the like.

In addition, since the support screw compresses the airtight material of the underframe material and the reaction force tightly engages the support screw with the support screw,
The frame body can be supported in an extremely stable state, and robust installation can be achieved.

Furthermore, since the underframe material is pressed and fixed by the support screws,
The base frame material can be fixed at the same time as the gate-shaped frame body.

Therefore, construction becomes very easy.
