Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a flush door, particularly a double-sided flush door.

BACKGROUND ART Conventionally, metal doors made of steel or aluminum have existed as a type of steel fittings.

Among these, double-sided flush doors in particular have greater strength than single-sided flush doors, and have many advantages such as high soundproofing and heat insulation effects, so they are widely used as residential or fire doors.

However, since the conventional flush door has the structure shown in FIGS. 1 and 2, it is unsatisfactory due to the following drawbacks in terms of manufacturing and product quality.

That is, in the conventional door of this kind, a core material 2 such as a heat insulating material or a soundproof material is loaded into a surface material 4 having a rectangular shape.
In addition, the four circumferences are simply attached with I-type or [-type edge material. Therefore, for example, when installing the locking metal fitting 3, the core material 2 at the location must be hollowed out to a predetermined size, and
A U-shaped wooden frame 5 is installed inside the edge material 1 to also reinforce the surface material 4 corresponding to this hollowed out part, and the mechanism body 3 of the metal fitting 3 is
It takes a lot of time and effort to manufacture the housing (a) within the frame of the wooden frame 5 (Fig. 2), and when trying to attach this pull fitting to a flush door, there is no space to effectively attach the main body of the mechanism. For this reason, it is difficult to attach a pull fitting to a flush door, and it is difficult to provide a flush door with a high degree of airtightness and/or watertightness. Conventional flush doors could not be used in areas requiring insulation.

Furthermore, the storage area of the mechanism main body 3a of the locking metal fitting 3 is not fully lined with the surface plate 4, so it easily cracks due to impact, making the product unsatisfactory.

The present invention was made in view of the above-mentioned drawbacks, and the main body of the flush door is reinforced by two surface materials, the front and back, a core material disposed between the surface materials, and a U-shaped cross section provided around the four peripheries. The reinforcing frame is arranged so that its sides are in contact with the surface material and the bottom is on the outside, and edge materials are provided around the four peripheries of the main body of the flush door, and the edge materials includes a horizontal plate that abuts and is fixed to the bottom of the reinforcing frame;
A protruding piece that clamps the surface material and the side part of the reinforcing material is integrally formed, and a hollow part is integrally formed on the edge material attached to the door edge side on the opposite side of the protruding piece. At the same time, by storing the main body of the mechanism such as a locking metal fitting or a pulling metal fitting in the hollow part, the metal fittings can be easily and effectively attached to the flush door, and the performance of the flush door can be further improved. It is something that

The present invention will be explained in detail below based on the embodiments shown in the drawings.

FIG. 4 is a cross-sectional view showing an embodiment of the flush door according to the present invention, in which the flush door 7 is attached to a hinge 8 which is fixed at one side so as to be openable and closable.

The flush door 7 is composed of a flush door main body 9, an edge member 12 and a hollow edge member 10 attached to one end of the main body 9, and upper and lower edge members (not shown).

The main body 9 can be made of any of the panel materials that constitute a normal flush door, but in this embodiment, the surface materials 11a and 11b and glass wool 15 as the core material are used.
was used.

Further, the flush door 7 according to the present invention has a surface material 11.
Atllb, the core material 15 disposed between the surface material 11ayllb, and the reinforcing frame 13.14 disposed between the surface material 11a and the llbl eye make up the flush door body 9.
It has sufficient strength and edge material 10.
12 can be attached.

That is, the hinge side is the surface material 11a. 11b are opposed to each other, and the negative end portion of each is connected to the horizontal plate 12a of the H-shaped edge material 12.
The U-shaped reinforcing frame 13 with its bottom 13a abutted against the horizontal plate 12a is sandwiched between the side parts 12b and 12c of the vertical frame 12 and the opposing side part 13be13c of the reinforcing frame 13. The other side ends of each reinforcing frame 14 are fixed by being brought into contact with the outside of the side parts 14b and 14c of the other reinforcing frame 14, and appropriate upper and lower edge materials (not shown) are attached to the main body 9. It constitutes a base frame, and the main body 9 is constructed by loading glass wool as a core material 15 such as a soundproofing material or a heat insulating material into the base frame.

The hollow edge material 10 has a hollow section 16 with a rectangular cross section that is open at both ends in the longitudinal direction, and opposite side sections corresponding to the indoor side and the outdoor side that constitute the hollow section 16 are extended respectively to form projecting pieces 10b and 10C. , and a fitting groove is formed in the longitudinal direction outside the hollow portion 16 together with the side portion 10a to which the protruding piece 10bvlOc is connected.

In order to attach the hollow edge material 10 to the side of the door edge of the flush door main body 9, the edge material 10 is attached so that the side part lea forming the hollow part 16 of the edge material 10 hits the bottom part 14a of the reinforcing frame 14. 10 is fitted into the side portion of the door edge of the main body 9, and the side portion 10a of the edge material 10 and the bottom portion 14a of the reinforcing frame 14 are appropriately fixed with bolts 17 or the like.

The outer shape of the side of the hollow edge material 10 opposite to the side on which the fitting groove is formed may vary depending on whether the door is single-opening or double-opening, and/or considering airtightness and watertightness. The design can be changed as appropriate, and FIG. 4 shows a single-door type with a protruding piece 10d that contacts the sealing member 18, and FIG. A retaining portion A having a shape suitable for engaging with the retaining portion A to ensure airtightness and watertightness is provided.

When attaching the locking fitting 3 or the pulling fitting to the flush door 7, the hollow part 1 of the hollow edge material 10 is
The mechanism bodies 3a, 6a of the metal fittings are housed in the metal fittings 6, and these metal fittings 3, 6 are attached in the same manner as a normal stile door.

For example, the locking fitting 3 can be attached to the hollow portion 16 of the hollow edge material 10 of the flush door 7 without making any features on the core material 15.
The pulling fitting 6 is installed in the same way as a normal frame door, and the pulling fitting 6 is installed by storing the main body 6a of the mechanism in the hollow part 16 of the hollow edge material 10 of the flat siding door 7, as shown in FIGS. 3a and 3b. Install in the same way as a stile door.

In addition, Fig. 3 a and b show the state in which the door D□ is pulled in the direction of the α arrow at the same time as the lock is locked, and when the handle H is turned in the direction of the β arrow, the door D□ is unlocked and the pulled state is removed. (shown by the broken line in Figure 3).

In addition, Fig. 3a. The pulling mechanism of the pulling fitting 6 in b is such that the rod 19 is moved in the α arrow direction (the door D1 is pulled in the C direction) or the β arrow direction (the door D1 is pulled in the C direction) by the rotation of the handle H.
Door D□ is released) and rod 1
This is done by sliding an inclined surface 19a formed at the tip of the roller 9 on the surface of the roller 20.

The door D1 is locked using the tongue E.

Reference numeral 18 is a sealing member.

As described above, according to the present invention, a hollow edge material that accommodates the main body of the mechanism such as a locking metal fitting or a pulling metal fitting is used as the edge material on the door end side of the flush door, so there is no need to create a core material when installing the metal fittings etc. This not only simplifies the installation work, but also reliably prevents water entering from the upper part of the pulling mechanism from wetting the core material.

In addition, according to the present invention, there is no need to perform work such as drilling or notching the metal fitting attachment part of the surface material as in the past, and it is possible to effectively attach the pulling metal fitting to the flush door, thereby improving the airtightness of the flush door. Watertight performance can be further improved, and soundproofing and/or heat insulation effects can be further improved.

Furthermore, the flush door according to the present invention has sufficient strength in the main body of the flush door, and the pulling fittings etc. are stored in the hollow part of the edge material, so they can be attached to the surface plate like conventional flush doors. It does not cause the Pecocchi phenomenon and is easy to manufacture.

It exhibits various excellent effects such as.
