[Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2001-303815 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in doors where an electric lock is installed, depending on the size of the door, the wiring cord that electrically connects the electric lock and the conductive metal fittings may have excess length. Therefore, in doors where an electric lock is installed, the excess wiring cord is stored in a wiring groove (corresponding to the cord storage groove in the above-mentioned Patent Document 1) provided in the upper part of the door body so that the excess wiring cord does not move. In that case, the strength of the upper part of the door body is reduced by the wiring groove, making it difficult to attach a door closer to the upper part of the door body.

[0006] The present invention has been made in consideration of these points, and its purpose is to ensure the strength of the upper part of the door body on a door on which an electric lock is installed, thereby making it possible to install a door closer. [Means for solving the problem]

[0008] According to the above configuration, in the rectangular outer frame, the first vertical frame on the door end side is provided with a first wiring passage that reaches the electric lock installation section, the second vertical frame on the door end side is provided with a second wiring passage that reaches the electric metal fitting installation section, and the first horizontal frame on the ceiling side is provided with a third wiring passage that communicates with the first and second wiring passages. Here, in the first horizontal frame that constitutes the upper part of the door body, the third wiring passage opens to the outside of the outer frame, and the height in the direction from inside the outer frame to the outside of the frame is relatively high on the door end side and relatively low on the door end side, and a step is provided between the door end side and the door end side. Therefore, a groove that opens to the outside of the outer frame is arranged on the door end side from the step of the third wiring passage, which is formed with a relatively low height in the direction from inside the outer frame to the outside of the frame. As a result, in the first horizontal frame, the bottom of the groove is located on the door end side from the step of the third wiring passage (where the door closer is attached), and the solid structure of the bottom ensures the strength of the upper part of the door body. Therefore, in doors where an electric lock is installed, the strength of the upper part of the door body can be ensured, making it possible to attach a door closer.

[0009] The third wiring passage may be provided so as to penetrate from the step to the door end side in a direction from inside the outer frame to outside the frame.

[0010] According to the above configuration, the third wiring passage is arranged so that the step penetrates from the door end side in the direction from inside the frame to outside the frame, so that the height (groove depth) from the step of the third wiring passage on the door end side in the direction from inside the frame to outside the frame can be made lower than the height from the step of the third wiring passage on the door end side in the direction from inside the frame to outside the frame.

[0011] A cover member for concealing the wiring cord housed on the door end side may be removably provided in the third wiring passage.

[0012] According to the above configuration, a removably provided cover member for concealing the wiring cord housed on the door end side is provided in the third wiring passage, thereby improving the appearance from outside the first horizontal frame. Effect of the Invention

[0013] According to the present invention, the third wiring passage opens to the outside of the outer frame, and its height in the direction from inside the outer frame to outside the frame is relatively high at the door edge side and relatively low at the door tail side, and a step is provided between the door edge side and the door tail side, so that in doors on which an electric lock is installed, the strength of the upper part of the door body can be ensured and a door closer can be installed.

[0024] The first panel 60a and the second panel 60b are made of wood materials such as MDF, plywood, LVL, laminated lumber, PB, CLT, PSL, OSB, solid wood, etc., or inorganic materials such as volcanic vitreous laminate boards and calcium silicate boards.

[0025] The door 80 described above is configured to be a hinged door, with the tail end side rotatably supported via three hinges H (see FIG. 1) on a door frame (not shown) provided at an indoor entrance of a building such as an office or commercial facility. The door 80 is configured to control opening and closing, for example, to close slowly, by a door closer 75 attached to the upper part of the tail end side and the door frame. The door 80 is also configured to be electrically locked and unlocked, for example, in response to card authentication, remote controller operation, etc., by an electric lock 72 on the front end side electrically connected to an electric fitting 71 on the tail end side via a wiring cord L.

[0026] Next, an example of a construction method including a wiring method for the door 80 of this embodiment will be described.

[0027] First, the wiring cord L of the conductive fitting 71 is passed through the second wiring path Pb from the end of the door 80 via the conductive fitting installation section C, and after the wiring cord L is entirely pulled out from the ceiling side of the door 80, the conductive fitting 71 is attached to the conductive fitting installation section C from the side of the end of the door 80.

[0028] Next, the pulled-out wiring cord L is passed through the first wiring path Pa on the door edge side of the door 80, the wiring cord L is pulled out slightly toward the door edge side of the door 80 through the electric lock installation section R, and the wiring cord L is connected to the electric lock (box lock) 72, and then the electric lock 72 is attached to the electric lock installation section R from the side of the door edge side of the door 80.

[0029] Thereafter, the remaining portion of the wiring cord L is placed in the third wiring path Pc so that the corresponding portion is accommodated on the door-end side of the step S of the third wiring path Pc.

[0030] Furthermore, after the handle 73 and the key cylinder 74 are attached to the electric lock 72, the door 80 is attached via three hinges H to a door frame provided at an indoor entrance, for example.

[0031] Finally, the door closer 75 is attached to the upper part of the trailing edge of the door 80 and the corresponding part of the door frame.

[0032] In this manner, the electric lock 72 and the like can be attached to the door 80. In the present embodiment, the method of installing the remaining portion of the wiring cord L in the third wiring path Pc has been exemplified, but the remaining portion of the wiring cord L may be installed in the current-carrying metal fitting installation portion C.

[0033] As described above, according to the door 80 of this embodiment, in the rectangular outer frame F, the first vertical frame Fa on the door end side is provided with the first wiring passage Pa that reaches the electric lock installation section R, the second vertical frame Fb on the door tail side is provided with the second wiring passage Pb that reaches the electric metal fitting installation section C, and the first horizontal frame Fc on the ceiling side is provided with the third wiring passage Pc that communicates with the first wiring passage Pa and the second wiring passage Pb. Here, in the first horizontal frame Fc that constitutes the upper part of the door body, the third wiring passage Pc opens to the outside of the frame of the outer frame F, and the height in the direction from inside the frame to outside the frame of the outer frame F is relatively high on the door end side and relatively low on the door tail side, and a step S is provided between the door end side and the door tail side. Therefore, a groove G that opens to the outside of the frame of the outer frame F is arranged on the door tail side from the step S of the third wiring passage Pc, which is formed to be relatively low in the direction from inside the frame to outside the frame of the outer frame F. As a result, in the first horizontal frame Fc, the bottom of the groove G is located on the door end side from the step S of the third wiring passage Pc where the door closer 75 is attached, and the strength of the upper part of the door body can be secured by the solid structure of the bottom. Therefore, in the door 80 on which the electric lock 72 is installed, the strength of the upper part of the door body can be secured, making it possible to attach the door closer 75.

[0034] Furthermore, according to the door 80 of this embodiment, the third wiring passage Pc is arranged so that the door end side penetrates from the step S of the third wiring passage Pc in the direction from inside the frame of the outer frame F to outside the frame, so that the height Tb (depth of groove G) from the step S of the third wiring passage Pc in the direction from inside the frame to outside the frame at the door end side can be made lower than the height Ta from the step S of the third wiring passage Pc in the direction from inside the frame of the outer frame F to outside the frame at the door end side.

[0035] Furthermore, according to the door 80 of this embodiment, when a cover member J that conceals the wiring cord L stored on the door end side is removably provided in the third wiring passage Pc, the appearance from outside the frame of the first horizontal frame Fc can be improved.

[0036] Other Embodiments In the above embodiments, a flush door with no lighting section is shown, but the present invention can be applied to a flush door with a lighting section in the upper half or the entire surface of the door body, or a slit-shaped lighting section in the door body. The present invention can also be applied to a door with a louver or a mirror panel in addition to the lighting section. [Industrial Applicability]

[0037] INDUSTRIAL APPLICABILITY As described above, the present invention is extremely useful in doors on which electric locks are installed, since it can ensure the strength of the upper part of the door body and enable the installation of a door closer. [Explanation of symbols]
