[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 3 show one embodiment of a door of the present invention. This door is an entrance door for an apartment building, and is attached to a frame (not shown) attached to an opening in the building frame with hinges 8 so that it opens to the outside. As shown in Figure 3, this door has a window 9 for admitting light at the upper position on the hanging side, and a mail slot 10 for receiving newspapers, mail, etc., located slightly below the center in the left-right direction.

[0010] As shown in Figures 1 and 2, this door has surface materials 1a and 1b made of steel plates on the exterior and interior surfaces, a core material 2 is provided inside the door sandwiched between the surface materials 1a and 1b, and a steel peripheral reinforcing material 11 is provided between the surface materials 1a and 1b so as to surround the periphery of the core material 2. For example, polystyrene foam or paper honeycomb is used as the core material 2, and the core material 2 is adhered to the backside of the surface materials 1a and 1b with an adhesive. The outer periphery reinforcement 11 is a long member with a U-shaped cross section that is open on the inner periphery and reinforces the outer periphery of the door. The outer peripheral edges of the exterior and interior surface materials 1a, 1b are bent to abut against the visible surface of the outer periphery reinforcement 11 and are fixed with rivets 19.

[0011] 1 and 2, the window section 9 is constructed by fitting glass (double-glazed glass) 3 into a frame 4 formed by vertical frame members 12, 12 and horizontal frame members 13, 13 with a roughly U-shaped cross section made of extruded aluminum alloy into a rectangular frame, via glazing channels 14, and the frame 4 with the fitted glass 3 is placed in a hole 7 formed in the core material 2 and positioned between the exterior and interior surface materials 1a, 1b, with an opening 6 formed so that the glass 3 is exposed on the surface materials 1a, 1b. The frame 4 is fixed to the surface materials 1a, 1b with rivets 15. In conventional doors, an opening for the window is formed in the surface material by press punching, and then a drawing process is performed to bend the edge of the opening toward the inside of the door.However, this door does not undergo such drawing process, and the edge 6a of the opening 6 is left cut and faces the inner periphery.

[0012] As shown in Figures 1 to 3, this door has moldings 16, 17 attached to the exterior and interior surfaces to hide the edge 6a of the opening 6. As shown in Figure 3(a), the exterior molding 16 is made up of a pair of vertical moldings 5, 5 provided over the entire vertical length of the surface material 1a, and a pair of horizontal moldings 18, 18 arranged between the vertical moldings 5, 5. As shown in Figure 1, the vertical molding 5 is formed from an extruded aluminum alloy profile, forming a thin, elongated, strip-like member with no hollow. The vertical molding 5 has a longitudinal groove 20 on its backside to accommodate rivets 15, and shallow longitudinal recesses on both sides of the groove 20 for attaching double-sided tapes 21, 21. The molding is attached to the surface material 1a using the two double-sided tapes 21, 21 attached to the recesses. The inner peripheral edge 5a of the vertical molding 5 is located inward of the edge 6a of the opening 6, and a sealing material attachment groove 22 is formed on its backside. A sealing material 23 is attached to the sealing material attachment groove 22. As shown in Figure 4, the sealing material 23 is only provided in the area of ​​the entire length of the vertical molding 5 where the opening 6 is formed in the surface material 1a. The sealing material 23 extends in the interior / exterior direction so that its tip is close to the glass 3, preventing the intrusion of dust and other foreign matter. The horizontal moldings 18, 18 are also formed as thin, solid, extruded aluminum alloy plates. As shown in FIG. 2, they have a recessed groove 20 on their back side to accommodate the rivet 15. They are attached to the surface material 1a with two double-sided tapes 21, 21 on either side of the recessed groove 20. The horizontal moldings 18, 18 have an inner peripheral edge 18a located inside the edge 6a of the opening 6, and a protrusion 24 at their inner peripheral end that protrudes toward the inside of the door, with the tip of the protrusion 24 close to the glass 3. Furthermore, the horizontal moldings 18, 18 have a positioning protrusion 25 formed at a position spaced from the outer peripheral side of the protrusion 24. The protrusion 25 is positioned in the inner and outer circumferential directions by abutting against the inner peripheral edge of the frame 4. Furthermore, the horizontal moldings 18, 18 are positioned in the left and right directions by abutting their left and right end faces 18b, 18b against the inner peripheral edges of the vertical moldings 5, 5, as shown in FIG. 3(a).

[0013] As shown in Figure 3(b), the interior molding 17 has a pair of vertical moldings 26, 26 with their longitudinal ends cut at a 45° angle and a pair of horizontal moldings 27, 27. The diagonal ends are butted together via L-shaped corner connectors (not shown) to form a rectangular frame. As shown in Figures 1 and 2, the vertical moldings 26, 26 and the horizontal moldings 27, 27 are formed from the same extruded aluminum material with a hollow portion 28. The back side has a recessed groove 29 for rivet 15, and the moldings are attached to the surface material 1b with double-sided tape 30, 30 provided on both sides of the recessed groove 29. The vertical moldings 26, 26 and the horizontal moldings 27, 27 have inner peripheral edges 26a, 27a located inside the edge 6a of the opening 6, and a protrusion 31 at the inner peripheral end that protrudes toward the inside of the door, with the tip of the protrusion 31 close to the glass 3.

[0014] Next, we will explain the assembly procedure for this door. First, adhesive is applied to the back surface of one of the surface materials 1a or 1b where the opening 6 is formed, and then the core material 2 with a hole 7 formed in it is placed on top of that. Then the frame 4 with the glass 3 fitted into the hole 7 of the core material 2 is placed, and the peripheral reinforcing material 11 is placed so as to surround the periphery of the core material 2. Next, adhesive is applied to the rear surface of the other surface material 1a or 1b in which the opening 6 is formed, and the other surface material 1a or 1b is placed on top of the other surface material 1a or 1b and bonded together. The molding 16 is then attached to the surface on the outside of the room. To attach the molding 16, first a predetermined length of tension material 23 is passed through the tension material attachment groove 22 of the vertical molding 5 on the hanging side, and the tension material 23 is positioned at a height corresponding to the range of the opening 6 in the surface material 1a, and the upper and lower ends of the tension material 23 are fixed with adhesive to prevent misalignment. Double-sided tape 21, 21 is also attached to both sides of the recessed groove 20 on the back side. Then, as shown in Figure 5-1, the upper end of the vertical molding 5 on the hanging side is aligned with the upper end of the surface material 1a, and it is positioned using a jig (not shown) so that it is a specified distance from the hanging side end of the surface material 1a, and is then adhesively attached to the surface material 1a using double-sided tape 21, 21 that has been previously attached to the backside. Next, as shown in Figure 5-2, the horizontal moldings 18, 18 are positioned in the left-right direction by butting their end faces 18b against the previously attached vertical molding 5, and the positioning protrusions 25 on the back side are positioned in the inner and outer circumferential directions by butting them against the inner edge of the frame 4, and then are adhesively attached to the surface material 1a using double-sided tape 21, 21 that has been previously attached to the back side. Next, the vertical molding 5 on the door end side is attached at a predetermined height by first attaching a predetermined length of tension material 23, and then aligning its upper end with the upper end of the surface material 1a as shown in Figure 5-3, and positioning it by butting it against the end faces 18a of the horizontal moldings 18, 18 that were attached earlier, and then adhesively attaching it to the surface material 1a with double-sided tape 21, 21 that was previously attached to the backside. Thereafter, the vertical moldings 26, 26 and the horizontal moldings 27, 27 are framed in a rectangular shape on the surface on the indoor side, and are then attached to the surface material 1b by means of double-sided tape 30, 30 attached to the back side.

[0015] As described above, this door comprises a pair of surface materials 1a, 1b, a core material 2 placed between surface materials 1a, 1b, a frame 4 with glass 3 fitted in it, and a molding (vertical molding on the outside of the room) 5, surface materials 1a, 1b have an opening 6 formed therein so that glass 3 is exposed, core material 2 has a hole 7 formed therein to fit frame 4, and frame 4 is placed in hole 7 in core material 2 and is arranged between surface materials 1a, 1b, and molding 5 is provided over the entire length of surface material 1a in the vertical direction, and hides the edge 6a of opening 6 in surface material 1a, so there is no need for drawing processing to bend the edge of opening 6 in surface material 1a toward the inside of the door, which makes it easier to manufacture doors with light window portions 9 and reduces costs. The molding 5 has a weatherstripping material 23 attached only to the area where the opening 6 of the surface material 1a is provided, and the weatherstripping material 23 narrows the gap between the molding 5 and the glass 3, preventing dust and the like from entering, and by changing the length and attachment position of the weatherstripping material 23, the position and size of the opening 6 can be flexibly changed. The molding 16 on the exterior side is made up of vertical moldings 5, 5 and horizontal moldings 18, 18 which are independent from each other and are attached by gluing them individually to the surface material 1a, allowing thin shaped materials to be used for the moldings 5, 5, 18, 18, improving the design and eliminating the need to frame the moldings 5, 5, 18, 18 or fix the moldings 5, 5, 18, 18 to the surface material 1a with screws, rivets or the like, thereby making it easier to manufacture the door and reducing costs.

[0016] The present invention is not limited to the above-described embodiments. The material and cross-sectional shape of the molding can be changed as needed. The molding may be a vertical and horizontal frame, or may be fixed to the surface material with screws, rivets, etc. The molding may be attached to either the exterior or interior side. The present invention is not limited to entrance doors, but can also be applied to back doors, interior doors, etc. [Explanation of symbols]
