[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-23799 Summary of the Invention [Problem to be solved by the invention]

[0004] Doors are required to ensure privacy for people inside and to improve lighting. [Means for solving the problem]

[0005] (1) A door that solves the above problem is a door that separates the outdoors from the indoors, and comprises a door body and a translucent body provided within the door body. The door body has an outdoor portion located on the outdoors side of the translucent body and an indoor portion located on the indoor side of the translucent body. The outdoor portion is provided with an outdoor slit extending in the height direction of the door body, and the indoor portion is provided with an indoor slit extending in the height direction of the door body. The outdoor slit extends at an angle to the thickness direction of the door body in a plan view. The indoor slit extends in the thickness direction of the door body in a plan view. An inner end portion of the outdoor slit in the thickness direction of the door body, which is located on the indoor side, is aligned with the indoor slit in the thickness direction of the door body.

[0006] With this configuration, the outdoor-side slit extends at an angle relative to the thickness direction of the door body in a plan view, making it more difficult for people outdoors to see the translucent body compared to when the slit extends in the thickness direction of the door body. Therefore, it becomes more difficult for people outdoors to see what is happening inside the building through the translucent body.

[0007] Furthermore, because the inner end of the outdoor slit is aligned with the indoor slit in the thickness direction of the door body, light can be taken in from outdoors through the outdoor slit, the translucent body, and the indoor slit. Because the indoor slit extends in the thickness direction of the door body in a plan view, it provides better daylighting than a slit extending at an angle to the thickness direction of the door body. This allows for improved daylighting while ensuring the privacy of people inside.

[0008] (2) In the door of (1) above, the entire outer end portion, which is the end portion of the outdoor slit in the thickness direction of the door body and is located on the outdoor side, is positioned at a position shifted in the width direction of the door body relative to the entire inner end portion of the outdoor slit.

[0009] With this configuration, people outdoors cannot see the light-transmitting body through the outdoor-side slit, making it more difficult for them to grasp what is happening inside the room, thereby ensuring the privacy of people indoors.

[0010] (3) In the door of (1) or (2) above, the door is a hinged door that is rotatably attached to the door frame via a hinge, and the outdoor slit is inclined so as to move away from the hinge in the thickness direction of the door body as it moves from the indoor side to the outdoor side.

[0011] With this configuration, when a person outside stands in front of the door and opens it to the outside, the direction of the outdoor slit changes to be parallel to the direction in which the person outside faces the door, making it easier for light from inside to reach the person outside. Therefore, the person outside can sense what is happening inside the door when they open it.

[0012] (4) In any one of the doors (1) to (3) above, the translucent body has an outdoor-side translucent member and an indoor-side translucent member located on the indoor side of the outdoor-side translucent member, and an air layer is provided between the outdoor-side translucent member and the indoor-side translucent member. According to this configuration, the air layer can improve the heat insulating properties of the translucent body.

[0013] (5) In the door of any one of (1) to (4) above, the outdoor slits and the indoor slits are provided in pairs at intervals in the width direction of the door body. This configuration improves the appearance of the door.

[0014] (6) The door of (5) above is provided with a bar-type outdoor handle provided on the outdoor surface of the door body and a bar-type indoor handle provided on the indoor surface of the door body, and the spacing between the two outdoor slits is the same as the width of the outdoor handle, and the spacing between the two indoor slits is the same as the width of the indoor handle. This configuration further improves the appearance of the door.

[0015] (7) In the door of (5) or (6) above, the translucent body is arranged in the width direction of the door body, from between one of the outdoor slits and one of the indoor slits to between the other of the outdoor slits and the other of the indoor slits.

[0016] This configuration makes installation easier than when a translucent body is individually installed between one outdoor slit and one indoor slit, and between the other outdoor slit and the other indoor slit.

[0017] (8) A building that solves the above problem includes any one of the doors described above in (1) to (7). With this configuration, the outdoor-side slit extends at an angle relative to the thickness direction of the door body in a plan view, making it more difficult for people outdoors to see the translucent body compared to when the slit extends in the thickness direction of the door body. Therefore, it becomes more difficult for people outdoors to see what is happening inside the building through the translucent body.

[0018] Furthermore, because the inner end of the outdoor slit is aligned with the indoor slit in the thickness direction of the door body, light can be taken in from outdoors through the outdoor slit, the translucent body, and the indoor slit. Because the indoor slit extends in the thickness direction of the door body in a plan view, it provides better daylighting than a slit extending at an angle to the thickness direction of the door body. This allows for improved daylighting while ensuring the privacy of people inside. [Effects of the Invention]

[0060] An outdoor slit S1 is provided in the outdoor portion 111. An indoor slit S2 is provided in the indoor portion 112. <Outdoor slit, indoor slit> As shown in FIG. 1 , the outdoor slit S1 extends in the height direction of the door body 11. In this embodiment, the outdoor slit S1 extends from the lower end to the upper end of the door body 11. In this embodiment, two outdoor slits S1 are provided spaced apart in the width direction of the door body 11. In the following description, one outdoor slit S1 is referred to as the first outdoor slit S11, and the other outdoor slit S1 is referred to as the second outdoor slit S12. The first outdoor slit S11 and the second outdoor slit S12 are provided in the center of the door body 11 in the width direction. A distance D1 between the first outdoor slit S11 and the second outdoor slit S12 is less than ¼ of the width W11 of the door body 11. In this embodiment, the distance D1 between the first outdoor slit S11 and the second outdoor slit S12 is the same as the width W12 of the outdoor handle 12.

[0061] As shown in Fig. 4, the first outdoor-side slit S11 of this embodiment is formed by a gap provided between the first outdoor-side slit-forming portion 21b of the first component part 20 and the third outdoor-side slit-forming portion 42 of the outdoor-side component part 40. The second outdoor-side slit S12 of this embodiment is formed by a gap provided between the second outdoor-side slit-forming portion 31b of the second component part 30 and the fourth outdoor-side slit-forming portion 43 of the outdoor-side component part 40. The width of the first outdoor-side slit S11 and the width of the second outdoor-side slit S12 are the same. The width of the first outdoor-side slit S11 and the width of the second outdoor-side slit S12 are each several millimeters.

[0062] As described above, the first to fourth outdoor-side slit forming portions 21b, 31b, 42, 43 extend so as to be inclined with respect to the thickness direction of the door body 11 in a plan view. Therefore, the first outdoor-side slit S11 and the second outdoor-side slit S12 each extend so as to be inclined with respect to the thickness direction of the door body 11 in a plan view. The first outdoor-side slit S11 and the second outdoor-side slit S12 extend parallel to each other. The first outdoor-side slit S11 and the second outdoor-side slit S12 are inclined at 60 degrees with respect to the thickness direction of the door body 11 in a plan view. The first outdoor-side slit S11 and the second outdoor-side slit S12 of this embodiment each incline so as to move away from the hinge 102 from the indoor side toward the outdoor side in the thickness direction of the door body 11.

[0063] 6, the outdoor slit S1 has an outer end S1a and an inner end S1b. The outer end S1a is an end of the outdoor slit S1 in the thickness direction of the door body 11 and is an end located on the outdoor side. The inner end S1b is an end of the outdoor slit S1 in the thickness direction of the door body 11 and is an end located on the indoor side.

[0064] As shown in FIG. 2 , the indoor side slit S2 extends in the height direction of the door body 11. In this embodiment, the indoor side slit S2 extends from the lower end to the upper end of the door body 11. In this embodiment, two indoor side slits S2 are provided at an interval in the width direction of the door body 11. In the following description, one indoor side slit S2 is referred to as the first indoor side slit S21, and the other indoor side slit S2 is referred to as the second indoor side slit S22. The first indoor side slit S21 and the second indoor side slit S22 are provided in the center of the door body 11 in the width direction. A distance D2 between the first indoor side slit S21 and the second indoor side slit S22 is less than ¼ of the width W11 of the door body 11. In this embodiment, the distance D2 between the first indoor side slit S21 and the second indoor side slit S22 is the same as the width W13 of the indoor side handle 13.

[0065] As shown in Fig. 4, the first indoor side slit S21 in this embodiment is formed by a gap provided between the first indoor side slit component 22b of the first component part 20 and the third indoor side slit component 52 of the indoor side component part 50. The second indoor side slit S22 in this embodiment is formed by a gap provided between the second indoor side slit component 32b of the second component part 30 and the fourth indoor side slit component 53 of the indoor side component part 50. The width of the first indoor side slit S21 and the width of the second indoor side slit S22 are the same. The width of the first indoor side slit S21 and the width of the second indoor side slit S22 are each several millimeters.

[0066] As described above, the first to fourth indoor side slit forming portions 22b, 32b, 52, 53 extend in the thickness direction of the door body 11 in plan view. Therefore, the first indoor side slit S21 and the second indoor side slit S22 each extend in the thickness direction of the door body 11 in plan view.

[0067] 6, the light-transmitting body 14 is provided between the outdoor-side slit S1 and the indoor-side slit S2. In this embodiment, the light-transmitting body 14 is provided in the width direction of the door body 11, from between the first outdoor-side slit S11 and the first indoor-side slit S21 to between the second outdoor-side slit S12 and the second indoor-side slit S22.

[0068] The outdoor-side slit S1 and the indoor-side slit S2 are configured to allow light to pass in and out between the outdoors and the indoors via the outdoor-side slit S1, the light-transmitting body 14, and the indoor-side slit S2. Specifically, the inner end S1b of the outdoor-side slit S1 is aligned with the indoor-side slit S2 in the thickness direction of the door body 11, with the light-transmitting body 14 interposed therebetween. In this embodiment, the entire inner end S1b of the outdoor-side slit S1 is aligned with the indoor-side slit S2 in the thickness direction of the door body 11, with the light-transmitting body 14 interposed therebetween.

[0069] The outdoor-side slit S1 of this embodiment is configured so that people outdoors cannot see the light-transmitting body 14 through the outdoor-side slit S1. Specifically, the entire outer end S1a of the outdoor-side slit S1 is provided at a position shifted in the width direction of the door body 11 with respect to the entire inner end S1b of the outdoor-side slit S1.

[0070] [Operation of this embodiment] The operation of this embodiment will be described. The building 100 is equipped with a door 10 that separates the outdoors from the indoors. The door 10 is equipped with a door body 11 and a light-transmitting body 14 provided within the door body 11. The door body 11 has an outdoor-side section 111 located on the outdoors side of the light-transmitting body 14, and an indoor-side section 112 located on the indoor side of the light-transmitting body 14. The outdoor-side section 111 is provided with an outdoor-side slit S1 extending in the height direction of the door body 11. The indoor-side section 112 is provided with an indoor-side slit S2 extending in the height direction of the door body 11.

[0071] The outdoor slit S1 extends at an angle relative to the thickness direction of the door body 11 in a plan view. The indoor slit S2 extends in the thickness direction of the door body 11 in a plan view. The inner end S1b of the outdoor slit S1 is aligned with the indoor slit S2 in the thickness direction of the door body 11.

[0072] Fig. 7 shows a state in which a person outdoors is standing in front of the closed door 10. Because the outdoor-side slit S1 extends at an angle relative to the thickness direction of the door body 11 in a plan view, it becomes difficult for the person outdoors to see the translucent body 14, as indicated by the dashed-dotted arrow in Fig. 7. Therefore, it becomes difficult for the person outdoors to grasp the situation inside the room through the translucent body 14.

[0073] Because the inner end S1b of the outdoor-side slit S1 is aligned with the indoor-side slit S2 in the thickness direction of the door body 11, light can be taken in from outdoors through the outdoor-side slit S1, the light-transmitting body 14, and the indoor-side slit S2, as shown by the solid arrows in Fig. 7. Because the indoor-side slit S2 extends in the thickness direction of the door body 11 in a plan view, it provides better daylighting properties than if it extended at an angle relative to the thickness direction of the door body 11. This allows for improved daylighting while ensuring the privacy of people inside.

[0074] [Effects of this embodiment] The effects of this embodiment will be described. (1) The outdoor-side slit S1 extends at an angle relative to the thickness direction of the door body 11 in a plan view. This makes it more difficult for people outdoors to see the translucent body 14 compared to when the outdoor-side slit S1 extends in the thickness direction of the door body 11. This makes it more difficult for people outdoors to see the situation inside the room through the translucent body 14.

[0075] Furthermore, the inner end S1b of the outdoor-side slit S1 is aligned with the indoor-side slit S2 in the thickness direction of the door body 11. This allows light to be taken in from outdoors through the outdoor-side slit S1, the light-transmitting body 14, and the indoor-side slit S2. Because the indoor-side slit S2 extends in the thickness direction of the door body 11 in a plan view, it provides better daylighting properties than if it extended at an angle relative to the thickness direction of the door body 11. This allows for improved daylighting while ensuring the privacy of people indoors.

[0076] (2) The entire outer end S1a of the outdoor-side slit S1 is positioned at a position offset in the width direction of the door body 11 with respect to the entire inner end S1b of the outdoor-side slit S1. With this configuration, people outdoors cannot see the translucent body 14 through the outdoor-side slit S1, making it more difficult for them to grasp what is happening inside the door. Therefore, the privacy of people indoors can be better ensured.

[0077] (3) The door 10 is a hinged door that is rotatably attached to a door frame 101 via hinges 102. The outdoor-side slit S1 is inclined in the thickness direction of the door body 11 so as to move away from the hinges 102 as it moves from the indoor side toward the outdoor side.

[0078] 8, when a person outside is standing in front of the door 10 and opens the door 10 to the outside, the direction in which the outdoor-side slit S1 extends changes to become parallel to the direction in which the person outside faces the door 10, making it easier for light from inside to reach the person outside. Therefore, when the person outside opens the door 10, they can sense what is happening inside the room.

[0079] (4) The light-transmitting body 14 has an outdoor-side light-transmitting member 14a and an indoor-side light-transmitting member 14b that is provided closer to the indoor side than the outdoor-side light-transmitting member 14a. An air layer 14c is provided between the outdoor-side light-transmitting member 14a and the indoor-side light-transmitting member 14b. With this configuration, the air layer 14c can improve the heat insulating properties of the light-transmitting body 14.

[0080] (5) The outdoor slits S1 and the indoor slits S2 are provided two by two with a gap between them in the width direction of the door body 11. This configuration can improve the appearance of the door 10.

[0081] (6) The door 10 is equipped with a bar-type outdoor handle 12 provided on the outer surface 11a of the door body 11, and a bar-type indoor handle 13 provided on the inner surface 11b of the door body 11. The distance D1 between the two outdoor slits S1 is the same as the width W12 of the outdoor handle 12. The distance D2 between the two indoor slits S2 is the same as the width W13 of the indoor handle 13. This configuration can further improve the appearance of the door 10.

[0082] (7) The translucent body 14 is provided from between the first outdoor-side slit S11 and the first indoor-side slit S21 to between the second outdoor-side slit S12 and the second indoor-side slit S22 in the width direction of the door body 11. This configuration makes installation easier than when the translucent body 14 is provided individually between the first outdoor-side slit S11 and the first indoor-side slit S21 and between the second outdoor-side slit S12 and the second indoor-side slit S22.

[0083] (8) When the outdoor-side slit S1 and the indoor-side slit S2 extend in the thickness direction of the door body 11 in a plan view, light enters from the outdoors into the indoors in a straight line. In contrast, in this embodiment, the outdoor-side slit S1 extends at an angle to the thickness direction of the door body 11 in a plan view, and the indoor-side slit S2 extends in the thickness direction of the door body 11 in a plan view. Therefore, light enters from the outdoors into the indoors while changing direction within the door body 11. This makes it possible to take in soft light from the outdoors into the indoors.

[0084] (9) The outdoor slit S1 and the indoor slit S2 each have a width of about several millimeters. This makes it difficult for a person outdoors to insert a tool into the outdoor slit S1 to destroy the light-transmitting body 14. Even if the light-transmitting body 14 is destroyed, it is difficult for a person outdoors to reach inside through the outdoor slit S1, the destroyed part of the light-transmitting body 14, and the indoor slit S2, making it difficult for the lock to be released. This improves security.

[0085] (10) The distance D1 between the first outdoor-side slit S11 and the second outdoor-side slit S12, and the distance D2 between the first indoor-side slit S21 and the second indoor-side slit S22 are each less than ¼ of the width W11 of the door body 11. In this way, the first outdoor-side slit S11 and the second outdoor-side slit S12 are closely spaced, and the first indoor-side slit S21 and the second indoor-side slit S22 are closely spaced, which makes it easier to ensure the amount of light that is taken in from outdoors to indoors.

[0086] (11) The outdoor-side light-transmitting member 14a is made of crime prevention glass. The indoor-side light-transmitting member 14b is made of glass. This reduces costs and improves crime prevention.

[0087] (12) The door 10 is not provided with a center sash. In this case, the exterior slit S1 and the interior slit S2 are not interrupted by the center sash, which improves the appearance of the door 10.

[0088] (13) The outdoor slit S1 is inclined at 60 degrees with respect to the thickness direction of the door body 11 in a plan view. This allows the outdoor slit S1 to be inclined with respect to the thickness direction of the door body 11 while ensuring the structural strength of the door body 11.

[0089] <Example of change> The above-described embodiments are examples of possible forms of the door 10 and the building 100, and are not intended to limit the forms.

The light-transmitting body 14 may be made of any material that can transmit light. For example, the light-transmitting body 14 may be made of frosted glass or colored glass, or may be made of a resin panel.

[0094] The number of outdoor slits S1 provided in the outdoor portion 111 and the number of indoor slits S2 provided in the indoor portion 112 may be changed as appropriate. For example, there may be one outdoor-side slit S1 and one indoor-side slit S2. Specifically, the door body 11 does not have the outdoor-side component 40 and the indoor-side component 50 of the above embodiment. The outdoor-side slit S1 is formed by a gap provided between the first outdoor-side slit component 21b of the first component 20 and the second outdoor-side slit component 31b of the second component 30. The indoor-side slit S2 is formed by a gap provided between the first indoor-side slit component 22b of the first component 20 and the second indoor-side slit component 32b of the second component 30.

[0095] In the above embodiment, the outdoor slits S1 are inclined at 60 degrees relative to the thickness direction of the door body 11 in a plan view, but the inclination angle of the outdoor slits S1 is not limited to this. The inclination angle of the outdoor slits S1 can be set within a range of 45 degrees to 75 degrees depending on the thickness of the outdoor component 40.

[0096] In the first outdoor-side slit S11, the third outdoor-side slit component 42 may extend so as to be inclined relative to the first outdoor-side slit component 21b in plan view. In the second outdoor-side slit S12, the fourth outdoor-side slit component 43 may extend so as to be inclined relative to the second outdoor-side slit component 31b in plan view.

[0097] The length of the outdoor slit S1 in the height direction of the door body 11 is not limited to the example in the above embodiment. The outdoor handle 12 and the outdoor handle 12 are not limited to bar-type handles. The outdoor handle 12 and the outdoor handle 12 may be, for example, a door knob.

[0098] The distance D1 between the two outdoor slits S1 may be different from the width W12 of the outdoor handle 12. The distance D2 between the two indoor slits S2 may be different from the width W13 of the indoor handle 13. Even in this case, at least the effect (1) of the above embodiment can be obtained.

[0099] The light-transmitting bodies 14 may be individually provided between the first outdoor-side slit S11 and the first indoor-side slit S21 and between the second outdoor-side slit S12 and the second indoor-side slit S22.
