DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The entrance door 10 is installed inside a door frame (not shown) installed in an opening of a building frame (not shown) so as to be able to open and close. In Figures 2 and 3, X1 indicates the outdoor side of the door body 1, and X2 indicates the indoor side of the door body 1. The left and right directions when facing the door body 1 are also referred to as left and right directions. The lateral direction of the door body 1 coincides with the left and right direction.

[0009] As shown in Fig. 1, the entrance door 10 includes a door body 1 and a plurality of hinges 11. The door body 1 of this embodiment is, for example, a swing door that can be opened and closed by rotating around the rotation axes of the plurality of hinges 11.

[0010] 1 and 2, the door body 1 comprises a frame material 2 formed into a rectangular frame by an upper material 21, a lower material 22, and a pair of vertical members 23, a light window 3 arranged within the frame material 2, a heat insulating material 4 arranged within the frame material 2 around the light window 3, a metal exterior side material 61 (surface material) covering the surface on the exterior side X1 of the heat insulating material 4, and a metal interior side material 62 (surface material) covering the surface on the interior side X2 of the heat insulating material 4. The heat insulating material 4 is provided in a space surrounded by the frame material 2, the exterior side material 61, and the interior side material 62.

[0011] The light window 3 is disposed in the left-right center of the door body 1, extending in the vertical direction. The light window 3 includes double-glazed glass 31 and an interior frame 32 that holds the peripheral edge of the interior side X2 of the double-glazed glass 31. As shown in Figures 1 and 2, the interior frame 32 holds the outer edge of the interior side X2 of the double-glazed glass 31. The interior frame 32 has an upper frame material 321, a lower frame material 322, and a pair of vertical frame materials 323.

[0012] The heat insulating material 4 is formed in a plate shape having a predetermined thickness. An exterior side surface material 61 is arranged on the exterior side X1 of the heat insulating material 4 so as to cover the surface of the exterior side X1 of the heat insulating material 4. An interior side surface material 62 is arranged on the interior side of the heat insulating material 4 so as to cover the surface of the interior side X2 of the heat insulating material 4.

[0013] The heat insulating material 4 includes a heat insulating material body 41, an opening 42 formed inside the heat insulating material body 41, and a heat insulating material lower portion 43 provided below the opening 42. The heat insulating material 4 is formed from, for example, expanded polystyrene.

[0014] The thermal insulation body 41 has a pair of vertical thermal insulation plate portions 411. The pair of vertical thermal insulation plate portions 411 are arranged on the outer sides of both the left and right sides of the opening 42 and the lower thermal insulation portion 43, and are formed in a plate shape extending over the entire area of ​​the thermal insulation material 4 in the up and down direction.

[0015] Opening 42 opens in a vertically long rectangle in the portion where double glazing 31 of light window 3 is arranged. Opening 42 penetrates through insulation material 4 in the thickness direction (indoor / outdoor direction). Light window 3 is arranged in opening 42.

[0016] The insulation lower portion 43 is located below the opening 42 in the insulation material 4, and is arranged inside in the left-right direction of the pair of insulation vertical plate portions 411 of the pair of insulation bodies 41. The insulation lower portion 43 is located below the opening 42 over the entire left-right area of ​​the opening 42.

[0017] 3 to 6, two slits 5 are formed in the lower part of the heat insulating material 43. Each of the two slits 5 is formed in a groove shape having a width in the left-right direction, and extends in the up-down direction at the lower end 421 of the opening 42, penetrating from the upper end surface 431 of the lower part of the heat insulating material 43 to the lower end 432.

[0018] The two slits 5 are provided at a distance from each other in the left-right direction at the lower end 421 of the opening 42. The two slits 5 penetrate from the lower end 421 of the opening 42 downward through the lower part 43 of the insulation material so as to move water that has traveled along the inside of the vertical frame material 323 (see FIG. 1 ) of the indoor-side frame 32 of the light-receiving window 3 and moved downward below the opening 42 to the outside below the insulation material 4.

[0019] The two slits 5 extend downward from a pair of lower corners 422 formed at both left-right ends of the lower end 421 of the opening 42. The slits 5 extend across the entire vertical area at both left-right ends of the lower insulation part 43, from the upper end surface 431 (upper end) to the lower end 432 of the lower insulation part 43. In this embodiment, the two slits 5 are formed at the boundary between the lower insulation part 43 and the pair of vertical insulation plate parts 411 of the insulation body 41.

[0020] In this embodiment, the lower end 421 of the opening 42 is formed by the upper end surface 431 of the lower portion of the insulation 43. The upper end surface 431 of the lower portion of the insulation 43 is formed in a flat shape that extends horizontally in the left-right direction and faces upward. The upper end surface 431 of the lower portion of the insulation 43 receives water that has entered the opening 42 of the insulation 4 and moved downward. The two slits 5 discharge water that has entered the opening 42 of the insulation 4 and been received on the upper end surface 431 of the lower portion of the insulation 43 to the outside of the insulation 4. The two slits 5 form a drainage structure.

[0021] As shown in FIGS. 4, 6 and 7, the two slits 5 are each formed to have a width in the left-right direction, and include an upper slit 51 and a lower slit 52.

[0022] The upper slit 51 is formed on the upper side of the slit 5 and extends from the upper end of the lower insulation portion 43 to partway down in the vertical direction. The upper slit 51 penetrates the lower insulation portion 43 in the thickness direction.

[0023] The lower slit 52 is formed on the lower side of the slit 5, and extends downward from the lower end of the upper slit 51 to the lower end 432 of the lower part of the insulation material 43. The lower slit 52 is formed in the shape of a groove recessed in a square shape from the surface of the lower part of the insulation material 43 facing the outdoor side X1 in the thickness direction of the lower part of the insulation material 43. The lower slit 52 may also be formed in the shape of a groove recessed in a square shape from the surface of the lower part of the insulation material 43 facing the indoor side X2 in the thickness direction of the lower part of the insulation material 43.

[0024] In the vertical range where the lower slits 52 are formed, a connecting portion 53 is formed in the portion on the indoor side X2 side in the thickness direction of the insulation lower portion 43 where the lower slits 52 are not formed. The connecting portion 53 connects the insulation lower portion 43 and the insulation vertical plate portion 411 at each of the left and right ends of the insulation lower portion 43. The insulation main body 41 and the insulation lower portion 43 are connected by the connecting portion 53 and are integrally configured.

[0025] Next, we will explain the flow of water in the drainage structure of door body 1. For example, if a heavy rain falls and water seeps into opening 42 in insulation material 4 where light window 3 of door body 1 is located, the water that has seenp into opening 42 will travel down opening 42 through a pair of vertical frame members 323 of interior frame 32 of light window 3, as shown in Figure 8.

[0026] Then, the water that reaches the upper end surface 431 of the lower part 43 of the insulation material 4 and is received by the upper end surface 431 penetrates into the upper slits 51 of two slits 5 formed at left and right intervals on the lower part 43 of the insulation material at both left and right ends of the upper end surface 431 of the lower part 43 of the insulation material.

[0027] Here, the upper slits 51 of the slits 5 are formed so as to penetrate the lower insulation portion 43 in the thickness direction, and therefore allow a large amount of water flowing on the upper end surface 431 of the lower insulation portion 43 of the insulation material 4 to penetrate. In addition, two upper slits 51 are formed spaced apart in the left-right direction of the lower insulation portion 43, and therefore a large amount of water flowing on the upper end surface 431 of the lower insulation portion 43 of the insulation material 4 can penetrate from two locations, the two upper slits 51.

[0028] As shown in FIG. 8 , water that has entered the upper slit 51 of the slit 5 moves from the upper slit 51 to the lower slit 52 and is discharged from the lower end of the lower slit 52 to the outside of the thermal insulation material 4. The water discharged to the outside of the thermal insulation material 4 is received by the lower material 22 and flows along the lower material 22 to both left-right end portions. The water flowing along the lower material 22 to both left-right end portions of the door body 1 is then discharged to the outside of the door body 1 through drainage holes 7 provided in the lower material 22 at both left-right end portions of the door body 1. The drainage holes 7 are holes that can discharge water to the outside of the door body 1 and are provided on both left-right end portions of the lower end of the door body 1 for drainage. This prevents water from entering the opening 42 of the thermal insulation material 4 from the lower end 421 of the opening 42 of the thermal insulation material 4 to the indoor side X2. This improves the drainage performance of the door body 1.

[0029] This embodiment provides the following advantages. In the drainage structure of the door body 1 of this embodiment, the insulating material 4 has an insulating material main body 41, an opening 42 formed inside the insulating material main body 41 and in which the light window 3 is disposed, and an insulating material lower portion 43 provided below the opening 42. The insulating material lower portion 43 has a groove-like slit 5 formed at the lower end 421 of the opening 42, penetrating vertically from the upper end surface 431 to the lower end 432 of the insulating material lower portion 43. As a result, by providing the slit 5 through which water can penetrate in the insulating material lower portion 43 located below the light window 3, even if water penetrates the opening 42 of the insulating material 4, it is possible to prevent the water from penetrating from the lower end 421 of the opening 42 of the insulating material 4 into the interior side X2. This improves the drainage performance of the door body 1.

[0030] In this embodiment, two slits 5 are provided at a distance in the left-right direction at the lower end 421 of the opening 42. This provides two portions through which water can enter, thereby further improving water drainage performance compared to providing one portion through which water can enter.

[0031] In this embodiment, the insulation material main body 41 and the insulation material lower portion 43 are integrally formed. This makes it easier for a person to carry the insulation material 4 and also easier to assemble when assembling the door body 1 than if the insulation material main body 41 and the insulation material lower portion 43 were formed separately. In other words, by integrally forming the insulation material main body 41 and the insulation material lower portion 43, handling is easier and productivity can be improved.

[0032] The present disclosure is not limited to the above-described embodiments, and includes modifications, improvements, etc. within the scope of achieving the object of the present disclosure.

[0033] For example, in the above embodiment, the thermal insulation material main body 41 and the lower portion of the thermal insulation material 43 are configured as a single unit, but this is not limiting. For example, two slits 5 may be provided at the lower end 421 of the opening 42, spaced apart in the left-right direction, and the two slits 5 may penetrate the lower portion of the thermal insulation material 43 in the thickness direction over the entire area of ​​the lower portion of the thermal insulation material 43 in the up-down direction. In this way, the thermal insulation material main body 41 and the lower portion of the thermal insulation material 43 may be configured as separate bodies separated by the two slits 5, with the lower portion of the thermal insulation material 43 being positioned inside the inner side of the thermal insulation material main body 41 in the left-right direction, with the two slits 5 sandwiched between them.

[0034] In addition, in the above embodiment, two slits 5 are provided, but this is not limitative. Only one slit may be provided, or three or more slits may be provided.

[0035] In the above embodiment, the two slits 5 are provided at the lower corners 422 at both left and right ends of the lower end 421 of the opening 42 of the heat insulating material 4, but this is not limiting. The slit 5 may also be provided midway along the left and right direction of the lower end 421 of the opening 42.

[0036] In the above embodiment, the door body 1 is configured as a hinged door that can be opened and closed by rotating around the rotation axis of the multiple hinges 11, but this is not limited to this. The door body may also be configured as a sliding door that can be opened and closed by moving left and right. [Explanation of symbols]
