Abstract

PURPOSE:To prevent generation of gaps between a central part frame and frame decorative plates by sticking the frame decorative plates on the front and rear faces of frame core materials fitted against the central part frame. CONSTITUTION:A door 1 is provided with upper/lower and right/left frames 2, a center part frame 3 fitted in a center opening surronded with them, and decorative members 5 decorating the outside end faces of upper/lower and right/left parts. At first to the four side parts of the center part frame 3, upper/ lower and right/left frame core materials 11 are fitted. Next frame decorative plates 12 are stuck on the front and rear faces of the frame core materials 11. Next after cutting off the outside end faces of the frame core materials 11 and the frame decorative plates 12, or without cutting off them, decorative edge materials 5 are fitted to the outside end faces of the frame cor materials 11 and the frame decorative plates 12. By manufacturing the door by sticking the frame decorative plates on the front and rear faces of the frame core materials after fitting the frame core materials to the central part frame in this way, gaps are not generated between the central part frame and the frame decorative plates, even if size accuracy of the center part frame is low.

There are drawbacks that a gap is generated between the edge portion and the central frame does not fit into the opening.

[0004]

[Means for Solving the Disadvantages] The present invention adopts the following means in order to eliminate the above disadvantages. Claim 1
Of the invention, the step of attaching the upper and lower, left and right frame core members to the four sides of the central frame, the step of attaching the frame decorative plate to the front and rear surfaces of the frame core member, and the outer end surface of the frame core member and the frame decorative plate. And a step of attaching a decorative edge material to the. According to the invention of claim 2, a step of mounting the central frame on the lower frame core material,
The process of attaching the upper and left frame cores to the upper and left and right sides of the central frame, the step of attaching the frame decoration plate to the front and rear surfaces of the frame core, and the outer end face of the frame core and the frame frame And a step of attaching a decorative edge material to the.

[0005]

The present invention has the following functions. After the frame core material is attached to the central frame, the frame is attached to the front and rear surfaces of the frame core to manufacture the door, so even if the size of the central frame is low, the center frame There is no gap between the frame and the frame decoration plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on two embodiments with reference to the drawings. The same members are designated by the same reference numerals in the two embodiments.

First, the door manufactured by the method of the first embodiment will be described with reference to FIGS. In this description, the front means the front side in FIG. 1, the rear means the back side, the left means the left side in FIG. 1, the right means the right side in the figure, and the inner side means the center side of the door and the outer side. Means outside the door.

The door 1 includes a top / bottom / right / left frame 2 and those frames 2
It has a central frame 3 fitted in a central opening surrounded by and a decorative edge member 5 made of a synthetic resin sheet, a projecting plate or the like for decorating the upper, lower, left and right outer end surfaces.

The frame 2 includes inner and outer frame core members 11,
Frame core material 11 for connecting the inner and outer frame core materials 11
And a frame decoration plate 12 attached to the front and rear surfaces of these frame core members 11. The frame decoration plate 12 projects inward from the inner frame core member 11. The front side frame decoration plate 1
An inclined surface 13 is formed on the inner side edge of 2 so as to spread to the front side. An inclined surface 13 is formed on the inner side edge of the rear frame decoration plate 12 and extends rearward.

As shown in FIG. 4, most of the left and right end surfaces of the upper and lower frame decoration plates 12 are inclined surfaces 13 of the left and right frame decoration plates 12.
And the same portion is formed as an inclined surface 18 forming a groove 17 in cooperation with the inclined surfaces 13 of the left and right frames 2. The groove 17 has a function of visually dividing the abutting portions of the frames 2 to make the deviation (step) of the frame decoration plate 12 in the front-rear direction inconspicuous.

The central frame 3 is provided with upper, lower, left and right core members 20.
And the molding 21 attached inside the front and rear parts of the core member 20.
And a glass plate 25 sandwiched between the front and rear moldings 21, and a grid 26 attached to the molding 21 so as to be located on the front and rear surfaces of the glass plate 25. As shown in FIG. 5, the molding 21 includes a slope 22 that abuts the slope 13 of the frame decoration plate 12, a slope 24 that forms the groove 17 with the slope 13, and a step where the core 20 is fitted. It has a section 23. The molding 21 is attached to the core member 20 by a nail or an adhesive as is well known. In addition, as shown in the figure,
The core member 20 is fitted between the front and rear frame decoration plates 12.

Embodiment 1 (see FIGS. 6 and 7) [First Step] Vertical and horizontal frame members 11 are attached to four sides of the central frame 3. [Second step] Frame decoration plates 12 are attached to the front and rear surfaces of the frame core material 11. [Third step] The decorative edge member 5 is attached to the outer end surfaces of the frame core material 11 and the frame decoration plate 12 after or without cutting the outer end surfaces of the frame core material 11 and the frame decoration plate 12.

Embodiment 2 (see FIGS. 8 to 10) [First Step] The central frame 3 is mounted on the lower frame core member 11. [Second step] The upper and right frame core members 11 are attached to the upper, left and right sides of the central frame 3. [Third step] Frame decoration plates 12 are attached to the front and rear surfaces of the frame core material 11. [Fourth step] The decorative edge material 5 is attached to the outer end surfaces of the frame core material 11 and the frame decoration plate 12 after or without cutting the outer end surfaces of the frame core material 11 and the frame decoration plate 12.

FIG. 11 shows an assembly plate 28 used in carrying out the method of the second embodiment. A stopper 29 that receives the lower frame core member 11 is attached to the lower end of the inclined assembly plate 28. The door 1 is manufactured by placing each member on the assembly plate 28.
