[Modes for carrying out the invention]

[0008] The embodiments of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited in any way to the embodiments described below, and may be implemented with appropriate modifications without departing from the spirit of this disclosure.

[0009] [First Embodiment] As shown in Figure 1, the joinery 100 comprises a door frame 10, a door body 20 and a side panel 19 which are installed inside the door frame 10 so as to be openable and closable, and a door closer 80 which electrically closes the door body 20. Hereinafter, as shown in Figure 1, the state in which the door body 20 and side panel 19 are closed will be referred to as the "closed door state".

[0010] As shown in Figure 4 below, two predetermined directions that are perpendicular to each other in the horizontal plane are referred to as the "X direction" and the "Y direction". One side of the X direction is called the "X- side", and the opposite side is called the "X+ side". Similarly, one side of the Y direction is called the "Y- side", and the opposite side is called the "Y+ side". The positional relationships of each component described below are those as viewed in the closed door state. In the following, the "X direction" may be read as the "width direction of the door body 20", and the "Y direction" may be read as the "thickness direction of the door body 20".

[0011] As shown in Figure 1, the door frame 10 comprises a vertical frame 11 on the X-side, an upper frame 12, a vertical frame 13 on the X+ side, and a lower frame 14. The two vertical frames 11 and 13 are spaced apart in the X direction and arranged side by side. Each vertical frame 11 and 13 extends in the vertical direction. The upper frame 12 and the lower frame 14 each extend in the X direction. The upper frame 12 connects the upper ends of the two vertical frames 11 and 13. The lower frame 14 connects the lower ends of the two vertical frames 11 and 13.

[0012] The long side of the door body 20 on the X-side is attached to the vertical frame 11 on the X-side via a hinge 31 shown in Figure 4, so that it can be opened and closed on an axis in the vertical direction. The long side of the sleeve portion 19 shown in Figure 1 on the X+ side is attached to the vertical frame 13 on the X+ side via a hinge or the like, so that it can be opened and closed on an axis in the vertical direction. As a result, the door body 20 and the sleeve portion 19 are installed inside the door frame 10, side by side in the X direction, so that they can be opened and closed.

[0013] As shown in FIG. 5, the door body 20 includes a vertical core material 21 on the X-side, an upper core material 22, a vertical core material 23 on the X+-side, a lower core material 24, an indoor side surface material 27, and an outdoor side surface material 28. Further, the door body 20 includes a heat insulating material 69 inside thereof. As shown in FIG. 6, the two vertical core materials 21, 23 are arranged side by side at intervals in the X direction. Each of the vertical core materials 21, 23 extends in the vertical direction. The upper core material 22 and the lower core material 24 each extend in the X direction. The upper core material 22 extends from a position adjacent to the upper end portion of the vertical core material 21 on the X-side to a position adjacent to the upper end portion of the vertical core material 23 on the X+-side. The lower core material 24 extends from a position adjacent to the lower end portion of the vertical core material 21 on the X-side to a position adjacent to the lower end portion of the vertical core material 23 on the X+-side.

[0014] As shown in FIG. 5, the indoor side surface material 27 constitutes the surface portion on the Y-side of the door body 20. A protruding portion 27e protruding to the Y+-side is provided at the edge of the indoor side surface material 27. An indoor side handle 37 extending in the vertical direction is attached to the end portion on the X+-side on the Y-side of the door body 20.

[0015] The outdoor side surface material 28 constitutes the surface portion on the Y+-side of the door body 20. An outdoor side handle 38 extending in the vertical direction is attached to the end portion on the X+-side on the Y+-side of the door body 20.

[0016] As shown in FIG. 5, the heat insulating material 69 is provided inside the door body 20, that is, in a portion surrounded by the vertical core material 21 on the X-side, the upper core material 22, the vertical core material 23 on the X+-side, the lower core material 24, the indoor side surface material 27, and the outdoor side surface material 28. In the present embodiment, the heat insulating material 69 is EPS (Expanded Poly-Styrene).

[0017] As shown in Fig. 5, a back plate 32 is provided at a portion located between the heat insulating material 69 and the indoor side surface material 27 at the X-side end of the upper edge of the door body 20. As shown in Fig. 7, a protrusion 32p protruding in the Y+ direction is provided at the upper part of the back plate 32. The protrusion 32p is fixed to the upper core material 22 by screws or the like. As shown in Fig. 5, the closer 80 is arranged on the Y - side of the indoor side surface material 27 and is fixed to the back plate 32 by screws or the like with the indoor side surface material 27 interposed therebetween. However, alternatively, a predetermined fixing fitting may be fixed to the back plate 32 with the indoor side surface material 27 interposed therebetween, and the closer 80 may be fixed to the fixing fitting. From these, as shown in Fig. 2, in the front view seen in the Y direction, the closer 80 is provided at a position overlapping the heat insulating material closer portion 50.

[0018] As shown in Fig. 7, the closer 80 includes a closer body 85, a link mechanism 86, and a closer wiring 82. The link mechanism 86 includes a plurality of joints 86j rotatable about the vertical axis. One end of the link mechanism 86 is rotatably attached to the closer body 85 about the vertical axis. The other end of the link mechanism 86 is attached to the upper frame 12. The closer body 85 is configured to be drivable to close the door body 20 electrically by acting on the link mechanism 86. The closer wiring 82 is a wiring for supplying power to the closer body 85. A connector is attached to the tip 82c of the closer wiring 82.

[0019] As shown in Figure 3, a power supply device 70 is installed inside the door body 20. As shown in Figure 9, the power supply device 70 comprises a power supply wiring 72, a mounting part 73, a power supply device body 75, and a connecting wiring 78. The mounting part 73 is a part for mounting the power supply device body 75 inside the door body 20 and is configured to be screw-fastened to the vertical core material 21 on the X- side. The power supply device body 75 protrudes from the vertical middle part of the mounting part 73 towards the X+ side. The power supply wiring 72 is wiring for supplying power to the power supply device body 75. The power supply wiring 72 extends to the power supply device body 75, for example, by passing through the inside of the wall surrounding the joinery 100 or the vertical frame 11 on the X- side. The connecting wiring 78 is wiring for electrically connecting the power supply device body 75 and the closer wiring 82. A connector is attached to the tip 78c of the connecting wiring 78. The connector on the tip 82c of the closer wiring 82 is connected to that connector.

[0020] The following describes in detail the structure of the part of the door body 20 shown in Figure 3 where the power supply 70 and closer wiring 82 are installed.

[0021] As shown in Figure 6, the insulation material 69 is divided into an insulation material main section 60, an insulation material closer section 50, and an insulation material wiring section 40. Both the insulation material closer section 50 and the insulation material wiring section 40 are smaller than the insulation material main section 60.

[0022] As shown in Figure 7, the insulation material closer section 50 constitutes the X-side end of the upper edge of the entire insulation material 69. The insulation material wiring section 40 also constitutes the upper end of the X-side edge of the entire insulation material 69. Therefore, the insulation material wiring section 40 extends downward from the lower surface of the X-side end of the insulation material closer section 50.

[0023] As shown in Figure 9, a storage recess 42 is provided at the lower part of the insulation material wiring section 40, which is recessed upward from the lower end. The storage recess 42 is open on both sides in the X direction. The inner space of the storage recess 42 constitutes most of the storage section St for housing the power supply unit body 75.

[0024] As shown in Figure 7, the vertical core material 21 on the X-side is provided with a through-hole 217 that penetrates in the X direction and communicates with the storage recess 42. As shown in Figure 5, the protruding portion 27e of the interior surface material 27 is provided with a through-hole 277 that penetrates in the X direction and communicates with the through-hole 217 of the vertical core material 21 on the X-side. These through-holes 217 and 277 also constitute a part of the storage section St, respectively.

[0025] As shown in Figure 9, a groove 45 is provided on the X+ side of the portion of the insulation wiring section 40 located above the storage recess 42, recessing toward the X- side and extending vertically. The groove 45 is open on both the upper and lower sides. Therefore, the lower end of this groove 45 communicates with the storage recess 42. The inner space of this groove 45 constitutes most of the wiring passage Wp for passing the closer wiring 82.

[0026] As shown in Figure 8, recesses 55 are provided on the lower surface of the insulation closer section 50, opening on both sides in the Y direction. The upper end of the groove 45 of the insulation wiring section 40 shown in Figure 7 is in communication with these recesses 55. These recesses 55 constitute the upper end of the wiring passage Wp. Within these recesses 55, a retaining groove 558 is provided for temporarily holding the tip 82c of the closer wiring 82 when the closer wiring 82 is installed. By fitting the tip of the connector into this retaining groove 558, the connector can be prevented from coming into contact with the adhesive on the indoor surface material 27.

[0027] As shown in Figure 7, the back plate 32 is provided with a through hole 328 that communicates with the recess 55. As shown in Figure 5, the indoor surface material 27 is provided with a through hole 278 that communicates with the through hole 328 of the back plate 32. Each of these through holes 328 and 278 also constitutes a part of the upper end of the wiring passage Wp.

[0028] Next, the closer installation method described above will be explained. This closer installation method can be performed not only when the door 100 is first installed, but also when the door 100 is being repaired. The closer installation method includes a wiring process, a closer installation process, a connection process, a power supply installation process, and a door installation process.

[0029] In the wiring process, first, as shown in Figure 4, the door body 20 is removed from the door frame 10, and the closer 80 and power supply unit 70 are removed from the door body 20. From this state, the worker inserts the tip 82c of the closer wiring 82, as shown in Figure 4, into the through hole 278 of the interior surface material 27, thereby inserting the tip 82c of the closer wiring 82 into the wiring passage Wp. From this state, the portions of the closer wiring 82 following the tip 82c are sequentially fed into the wiring passage Wp. At this time, the closer wiring 82 hangs downward due to its own weight. Therefore, by feeding it in this sequential manner, the tip 82c of the closer wiring 82 can reach the storage section St.

[0030] In the subsequent door closer installation process, workers secure the door closer 80 to the door body 20 using screws or other means.

[0031] In the subsequent connection process, the worker connects the tip 82c of the closer wiring 82 that has reached the storage section St to the tip 78c of the connection wiring 78 of the power supply device 70 shown in Figure 9. This electrically connects the closer wiring 82 to the power supply device 70. This connection process may be performed before the closer installation process.

[0032] In the power supply installation process, which follows the connection process, a worker attaches the power supply 70 to the storage compartment St by screwing the mounting portion 73 of the power supply 70 shown in Figure 4 to the long side of the door body 20 on the X-side.

[0033] In the subsequent door installation process, the worker screws the hinge 31, which is attached to the long side of the door body 20 on the X-side, to the vertical frame 11 on the X-side, as shown in Figure 4. This rotatably attaches the long side of the door body 20 on the X-side to the vertical frame 11 on the X-side.

[0034] As described above, the power supply unit 70 and closer wiring 82 can be installed inside the door body 20, as shown in Figure 3, and the installation of the door fitting 100 can be completed.

[0035] The configuration and effects of this embodiment are summarized below.

[0036] As shown in Figure 3, the closer wiring 82 extends from the power supply through the inside of the door body 20 to the electric closer 80. Therefore, as shown in Figure 2, the closer wiring 82 can be concealed to improve the aesthetic design of the joinery 100.

[0037] As shown in Figure 3, a wiring passage Wp is provided inside the insulation material 69 located inside the door body 20. The closer wiring 82 passes through this wiring passage Wp. Therefore, even when the insulation material 69 is installed inside the door body 20, the closer wiring 82 can be installed inside the door body 20.

[0038] As shown in Figure 7, the thermal insulation material 69 is divided into multiple components. The majority of the wiring passage Wp is provided in the thermal insulation material wiring section 40. Therefore, it is easier to provide the wiring passage Wp inside the thermal insulation material 69 compared to when the entire thermal insulation material 69 is formed as a single unit.

[0039] As shown in Figure 9, the insulation material wiring section 40 is provided with a groove 45 that extends vertically and opens to the X+ side. The opening of the groove 45 on the X+ side is closed by the main insulation material section 60, so that a wiring passage Wp is formed in the shape of a hole inside the insulation material 69, as shown in Figure 3. Thus, a hole-shaped wiring passage Wp can be simply provided inside the insulation material 69.

[0040] As shown in Figure 9, a storage compartment St is provided on the inside of the lower part of the insulation material wiring section 40. The wiring passage Wp is connected to this storage compartment St. By providing not only the wiring passage Wp but also the storage compartment St on the inside of the insulation material wiring section 40 in this way, it becomes easier to install the storage compartment St inside the insulation material 69.

[0041] As shown in Figure 7, the insulation material 69 includes an insulation material closer portion 50. A recess 55 is provided at the lower part of the insulation material closer portion 50, which constitutes the upper end of the wiring passage Wp. Therefore, the upper end of the wiring passage Wp shown in Figure 3 can be provided simply.

[0042] As shown in Figure 3, in a front view in the Y direction, the wiring passage Wp extends straight downward from the closer 80 and communicates with the storage section St. Therefore, the closer wiring 82 shown in Figure 4 can be routed down to the storage section St simply by inserting its tip 82c into the upper opening of the wiring passage Wp shown in Figure 3. Thus, the closer wiring 82 can be easily connected to the power supply 70.

[0043] As shown in Figure 3, the door body 20 has a recessed storage compartment St on the long side on the X-side, which, when the door is closed, is blocked by the vertical frame 11 on the X-side. The power supply unit 70 is stored in this storage compartment St. Therefore, when the door is closed, as shown in Figure 2, the storage compartment St and the power supply unit 70 are hidden by the door frame 10 and the door body 20. As a result, when the door is closed, the storage compartment St and the power supply unit 70 are not visible from either the inside or the outside. This improves the aesthetic design of the door 100.

[0044] As shown in Figure 7, a backing plate 32 is provided between the closer 80 and the insulation material 69. A through-hole 328 for passing the closer wiring 82 is provided in the backing plate 32. Therefore, even when the backing plate 32 is present, the closer wiring 82 can be inserted into the wiring passage Wp through the through-hole 328 in the backing plate 32.

[0045] As shown in Figure 7, the backing plate 32 is fixed to the upper core material 22 of the door body 20 with screws. This allows the backing plate 32 to be easily positioned within the door body 20. As a result, the through-hole 328 of the backing plate 32 can be easily positioned directly in front of the recess 55 of the insulation closer part 50.

[0046] [Other embodiments] The above embodiments can be implemented with modifications as follows, for example: The closer 80 may be a concealed type closer installed inside the door body 20. The joinery 100 may be equipped with an automatic opening and closing device that electrically opens and closes the door body 20. The closer 80 may constitute a part of that automatic opening and closing device. [Explanation of symbols]
