Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flush door attached to a doorway or a window of a house.

[0002]

[Prior art]

 Flush doors are based on a structure in which plates are attached to both sides of the heartwood, and are framed by left and right vertical frames and upper and lower frames. Are assembled by. In the case where an aluminum extruded profile is used for the frame (also called edge), as shown in Fig. 8, a paper honeycomb or urethane foam material is used for the core material 30, and the face material is used for both sides. A frame is formed by bonding an aluminum edge 34 to the one obtained by pasting 32, 32 together.

[0003]

[Problems to be solved by the device]

 According to the conventional flush door as described above, the number of members is large and the assembling is not easy. Especially, in the case of a wooden body, since craftsmanship is required, it is not suitable for mass production. Further, in the case of aluminum, the structure of the core material is simple, and therefore it is relatively suitable for mass production, but it is not easy to assemble the aluminum edge 34.

That is, in the case of aluminum, the aluminum edge has a pair of long holding pieces 36, 36 for holding the core material 30, and short outer edge pieces 38, 38 hanging on the ends of the face materials 32, 32. Therefore, since it takes a certain amount of skill to bond the aluminum edge 34 while incorporating it, further improvement was required in terms of mass production. There was also a risk that the aluminum edge would be removed.

In view of the above situation, the present invention aims at providing a flush door suitable for mass production and excellent in durability because it requires almost no labor for assembling. .

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is mainly composed of a panel made of an extruded profile in which a large number of vertical walls are arranged between front and back double-sided walls, and the upper and lower ends of the panel are arranged along the edges. It is enclosed by a horizontally long plastic cap, and the cap has a multi-legged fitting that closely fits in the hollow between the vertical walls of the panel, and the flush door has both ends of the panel as the ends of the door. Configured.

Further, the panel may be composed of a plurality of panels each having a convex portion and a concave groove that are fitted to each other, and the connection may be held by upper and lower caps.

[0008]

[Work]

 According to the above structure, the main body of the door is made up of the combination of the panel and the upper and lower caps, and the fitting portion of the cap is pushed into the hollow of the panel to facilitate the combination. Also, since there are no vertical frames or edges on the left and right, it will not come off.

The panel has a rib structure in which both side walls are connected to each other by a large number of vertical walls, and furthermore, functions such as heat insulation and soundproofing are exhibited by the air. Further, when the panels are formed by joining a plurality of panels, the fitting portion of the cap is fitted across the hollows of both panels, so that stable joining strength is maintained.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 3 show an example implemented as an opening / closing door of a bathroom, in which a window frame F is fitted to an entrance into a bathroom B, and a flush door D is attached to the opening / closing door so as to be openable / closable. Note that the same can be applied to the front door, the self-service door, etc.

The flush door D is a vertically extruded plastic panel P in which upper and lower ends are fitted with caps 1 and 1 for sealing the ends, and upper and lower bearing members 5 and 7 are attached to one end. The handle 9 which can be locked is attached to the other end.

The panel P is formed by extrusion molding integrally over the entire width, and regarding the cross-sectional structure, a large number of vertical walls 13, 13, ... Are arranged between the double-sided walls 11, 11. A hollow space 14 is formed between the vertical walls 13, 13. There is a fixed space between the vertical walls 13 and 13, but on the mounting side of the handles 9 and 9 the space is narrow and dense to firmly support the handles 9 and 9 and the key 10. A wall 13 is formed. With respect to the key 10, a lock 12 coming in and going out by the handles 9 and 9 projects from the end surface of the panel P 1.

Further, the panel P has a curved end surface wall 15 at the end on the pivot side so as not to be supported by the window frame F by the opening / closing operation, and has a shallow groove-shaped thickness at the end on the locking side for reinforcement. Meat end walls 17 are formed respectively. An access hole for the lock 12 is provided on the thick end face wall 17.

The caps 1, 1 are injection-molded of plastic, and mainly have a horizontally long portion exposed along the edge of the panel P, and the hollows 14, 14, ... The fitting portions 19, 19, ..., Which fit, are projected in a multi-legged shape (see FIG. 5), and are integrated with the panel P by fitting and bonding. The bearings 5, 7 are attached to the caps 1, 1.

The window frame F is framed by the upper and lower frames 21, 22 and the left and right vertical frames 23, 24, of which the dovetail groove 25 is formed in the upper frame 21. The upper support 5 is provided with a shaft 29 in a portion fitted into the dovetail groove 25. Further, a lower rail 31 is provided on the lower frame 22 in a protruding manner, and a shaft is attached to a portion hanging on the lower rail 31. The upper and lower supports 5, 7 are always fixed to the upper frame 21 and the lower frame 22, respectively, but they can be released from the fixed state and transferred to the opposite side of the window frame F. That is, the opening / closing side of the flash door D can be changed.

As for the changer on the opening / closing side of the door, the left and right vertical frames 23, 24 are provided with mounting holes for the lock receiver 35, one of which is the lock receiver 35 and the other of which is the cap 37 so that they can be exchanged with each other. It is worn. The lock 12 can be turned inside out.

FIG. 4 and FIG. 5 show an example implemented as a sliding door. In this case, the panel P is a combination of two panels Pa and Pb each made of an extruded profile, and For this reason, a dovetail-shaped convex portion 39 is formed on one panel Pa, and a dovetail-shaped concave groove 41 into which it cannot be removed is formed on the other panel Pb.

Although the cap 1 may be integrally molded in the same manner as in the above-described embodiment, in this embodiment, the three caps 1a, 1b, 1c are one. The connecting portion is different in position so that it can be supported without bending with respect to the panel P. Since the caps 1, 1 have fitting portions 19, 19, ... That fit into the hollows 14, 14, ... Of the panels Pa, Pb, a strong connection state can be obtained.

Regarding the panel P, since a desired width is obtained by joining a plurality of panels in this manner and the panel P can be held as a single piece by the upper and lower caps 1 and 1, a convex portion for connection is formed. 39 and the concave groove 41 may have a simple straight shape as shown in FIG. Further, in the case of the same figure, the two panels Pa and Pb have the same width, but a combination of different widths such as a combination of the panel Pa of FIG. 6 and the panel Pb of FIG. 7 may be used.

[0021]

[Effect of device]

 As described above, according to the flush door of the present invention, the door main body is simply the combination of the panel and the upper and lower caps, and the fitting portion of the cap is pushed into the hollow of the panel so that the combination is achieved. Since it can be easily done, it is suitable for mass production without requiring much labor for assembling. In addition, since the panel is extruded and has a rib structure, which does not have a rigid frame, it exhibits excellent durability as well as excellent heat insulation and soundproofing.

Even when a panel is formed by joining a plurality of panels (Claim 2), since the fitting portion of the cap is fitted across the hollows of both panels, a stable joining strength is obtained. Hold.
