Abstract

PURPOSE:To ensure resistance against an impact force applied to a door panel by bonding a surface plate of a size suitable for fitting within a door frame to both inside and outside of a core plate larger than the inner width of the door frame, and coupling the peripheral edge of the core plate to an engagement groove formed on the door frame. CONSTITUTION:A door panel 7 to be coupled to a door frame 1 is constituted with a core plate 7a larger than the inner width of the door frame 1 in every direction, and surface plates 7b and 7b of a size suitable for coupling within the door frame 1 bonded to both inside and outside of the core plate 7a. Furthermore, the peripheral edge of the core plate 7a is coupled to a door panel engagement groove 9 formed all around the internal surface of the door frame 1. According to the aforesaid construction, an impact working on the door panel 7 is absorbed by the door frame 1, thereby enabling the prevention of the disengagement of the door panel 7 and the separation of a casing material 8.

Description

[Detailed description of the invention] This invention relates to a flush door.

As a type of door with a flush structure, a door panel is fitted into the door frame, and the periphery of this door panel is surrounded by a pair of front and back frame materials that are glued to the inner peripheral surface of the door frame with the door panel sandwiched between them. Some have a sandwiched structure. Figures 1 and 2 show conventionally known doors of this type. In the figures, 1 is a door frame, and this door frame 1 is made from a pair of inner and outer vertical frames 2a and 3a. A decorative board (decorative veneer board) is applied to each of the front and back sides of the core frame, which is a combination of two sets of vertical stile core materials on the left and right, and two sets of upper and lower horizontal stile core materials, consisting of a pair of inner and outer horizontal stile materials 2b and 3b. It has a structure in which a frame surface plate 4.4 cut out in the shape of a frame is glued. In addition, in the figure, 5 is a paper honeycomb core provided in the gap in the door frame 1 to support the frame surface plate 4゜4 from the inside, and 6 is an end plate glued to both end faces of the door frame 1. . In addition, 7 is a door panel, and this door panel 7
The front and back surfaces of a core board 7a made of plywood are laminated with face plates 7b and 7b made of decorative boards. Cut-out decorative boards are used. This door plate panel 7 is fitted into the door frame 1, and the inner peripheral surface of the door frame 1 (inner frame materials 2a, 2b
It is held between a pair of front and back frame materials 8, 8 which are adhered to the inner peripheral surface of the frame.

However, since the above-mentioned conventional door only has a frame material 8.8 sandwiching the periphery of the door panel 7, if a person bumps into the door and a shock is applied to the door panel 7. This impact force causes the frame material 8 on the opposite side to the side to which the impact is applied to peel off, and the door panel 7 comes off together with the frame material 8.

This invention was made in view of the above-mentioned circumstances, and its purpose is to prevent the door panel from coming off or the frame material from peeling off even if an impact is applied to the door panel. It's about providing a door.

That is, in the door of the present invention, the door panel is fitted into the door frame, and the front and back sides of the core plate, which is larger than the upper, lower, left, and right inner widths of the door frame, are provided with face plates of a thickness that fits into the door frame. By fitting the peripheral edge of the core plate of this door panel into the door panel fitting groove provided on the inner peripheral surface of the door frame all around the door frame, the door panel is attached to the door. This structure is such that the door frame receives the impact force applied to the door panel by holding it in the frame.

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 3, 1 is the door frame %2a, 3a is the vertical frame material of this door frame 1, 4 is the frame surface plate, 6 is the end plate, 7 is the door panel, and 8 and 8 are the frame materials. The door panel 7 has a core plate 7a made of a plywood board that is slightly larger than the inside 111 of the lower left and right sides of the door frame 1, and a front plate made of a decorative board bonded to both the front and back sides of the core plate 7a. The face plates 7b, 7b have a structure that is sized to fit almost tightly into the door frame 1. Reference numeral 9 denotes a door panel fitting groove provided on the inner peripheral surface of the door frame 1 (inner peripheral surface of the inner frame material 2a) over the entire circumference of the door frame; Face plate 7b
, 7b is fitted into the door plate panel fitting groove 9 and held in the door frame 1, and the periphery of the door plate panel 7 is surrounded by this door plate. Panel 7
It is held between a pair of front and back frame members 8, 8 which are glued to the inner circumferential surface of the door frame 1. Furthermore, the peripheral edge of the door panel 7 that fits into the door panel fitting groove 9 is firmly fixed to the door frame 1 by being glued into the groove 9 or tightly fitted into the groove 9 by press fitting. has been done. This door has the same structure as the conventional door shown in FIGS. 1 and 2, except that the peripheral edge of the door frame panel 7 is held on the inner periphery of the door frame 1. It has become. In addition, this door has vertical and horizontal inner frame members 2a, 2b around the door panel 7.
(see Fig. 1), and then arrange the vertical and horizontal outer stile materials 3a and 3b (see Fig. 1) on the outside to assemble the stile core material, and then glue the stile surface plates 4, 4. , then picture frame material 8
, 8 (the frame materials 8, 8 may be bonded only to the door frame 1, or may be bonded to both the door frame 1 and the door plate panel 7).

However, since this door has the periphery of the door panel 7 held directly by the door frame 1, even if an impact is applied to the door panel 7, this impact force will be stopped by the door frame 1. Therefore, the door panel 7 will not come off, and the frame material 8 will not peel off due to impact force being applied to the frame material 8.

Moreover, in this door, the core plate 7a of the door plate panel 7 is attached to the door frame 1.
Fit only the peripheral edge of the core plate 7a into the door plate panel fitting groove 9 of the door frame 1, and the surface plates 7b and 7b of the door plate panel 7 are fitted into the door frame 1. Since it is sized to fit inside, the front and back surface plates 7b, 7b of the door panel 7
As such, it is possible to use the remaining decorative board obtained by cutting out the front and back frame surface boards 4.4 of the door frame 1 into a frame shape, and therefore,
Although the peripheral edge of the door panel 7 is fitted into the door panel fitting groove 9 of the door frame 1 to prevent the door panel 7 from coming off and the frame material 8 from peeling off, Frame surface plate 4
and the surface plate 7b of the door panel 7 can be cut from the same decorative board to save material costs and reduce the manufacturing cost of the door.

Since the door of this invention is as described above, even if an impact is applied to the door panel, the door panel will not come off or the frame material will not peel off, and moreover, the periphery of the core plate of the door panel The front panel of the door panel fits into the door panel fitting groove of the door frame, and the surface plate of the door panel is sized to fit within the door frame, so it can be used as the front and back surface plates of the door frame. Since you can use the remaining decorative board that has been cut out into a frame shape from the front and back stile surface panels, you can remove the door panel by fitting the peripheral edge of the door panel into the door panel fitting groove of the door frame. While this is designed to prevent the frame material from peeling off, the door frame face plate and the door panel face plate are cut from the same decorative board, saving material costs and reducing door manufacturing costs. can do.
