For the purpose of explaining the thermal insulation structure, Figure 4 omits some components such as reinforcing members 51 and 52 from the vertical cross-sectional view of the upper frame portion of the entrance door shown in Figures 1 and 5.

[0029] The main body portion 111a of the metal upper frame material 111 has a depth dimension greater than the depth dimension of the insulated door 15. When the insulated door 15 is closed, the indoor facing surface 111c of the main body portion 111a is located on the indoor side 15a of the insulated door 15, and the position in the depth direction of the indoor side 111e that partitions the corner space S1 is approximately the same as the position in the depth direction of the indoor side 15a of the insulated door 15.

[0030] The metal upper frame material 111 is provided with engaging portions 111f and 111g on its inner circumferential surface 111d and indoor side surface 111e, respectively, which partition the inner corner space S1, for attaching the resin upper frame material 112.

Furthermore, on the upper frame 11, a tight seal s11 attached to the tight seal attachment part 112j abuts against the indoor side surface 15a of the insulated door 15 on the inner circumference (indoor side) of the contact portion between the indoor side surface (contact surface) 111e of the metal upper frame material 111 and the attachment part 112a of the resin upper frame material 112, forming a tight seal t11. An insulating space R1 formed by resin material is provided on the indoor side of the opposing surfaces between the insulated door 15 and the metal upper frame material 111.

[0040] The upper frame 11 has a portion of the mounting part 112a of the resin upper frame material 112 that is partially cut out. In the cutout portion, as shown in Figure 5, a reinforcing member 51 with a roughly L-shaped cross-section is arranged from the indoor side surface 111e of the metal upper frame material 111 to the outer peripheral side surface of the recessed wall portion 112d of the resin upper frame material 112.

[0041] As shown in Figure 3, the reinforcing member 51 is a steel member consisting of a visible portion 51a and a recessed portion 51b. The visible portion 51a is fixed to the metal upper frame material 111 by screws (fixing means) b1 via a reinforcing member (back plate) 53 positioned inside the main body portion 111a of the metal upper frame material 111.

[0042] The upper frame 11 has a hollow section formed by a resin upper frame material 112 and an auxiliary frame material 113, in which a reinforcing member 52 with a roughly U-shaped cross-section is positioned with one side 52a of the U-shape facing upwards and the other side 52b facing downwards. One side 52a of the reinforcing member 52 and the facing wall 51b of a reinforcing member 51 positioned on the indoor side of the metal upper frame material 111 are connected by screws (fixing means) b2.

[0043] The upper frame 11 is configured such that the frame-side arm 61a of the link mechanism 61 of the door closer 6, which is mounted on the indoor side, is connected to the other side 52b of the reinforcing member 52 located in the hollow section by screws (fixing means) b3, sandwiching the main body 113a of the auxiliary frame material 113. The link mechanism 61 of the door closer 6, which is connected to the inner circumference of the resin auxiliary frame material 113, is connected to the metal upper frame material 111, thereby enabling the door closer 6 to operate stably.

[0045] The main body portion 131a of the metal vertical frame material 131 has a depth dimension greater than the depth dimension of the insulated door 15. When the insulated door 15 is closed, the indoor facing surface 131c of the main body portion 131a is located on the indoor side 15a of the insulated door 15, and the position in the depth direction of the indoor side 131e that partitions the corner space S3 is approximately the same as the position in the depth direction of the indoor side 15a of the insulated door 15.

[0046] The metal vertical frame member 131 is provided with engaging portions 131f and 131g on its inner circumferential surface 131d and indoor side surface 131e, respectively, for attaching the resin vertical frame member 132 to the inner corner space S3.

[0051] The auxiliary frame material 133 of the vertical frame 13 of the entrance door in this embodiment has a main body portion 133a with a hollow section, an inner peripheral wall portion 133b extending to the outdoor side of the main body portion 133a, engaging claws 133c, 133c formed on the outer peripheral surface of the hollow section of the main body portion 133a, and an engaging portion 133d extending outward from the outer peripheral surface of the inner peripheral wall portion 133b.

[0052] The auxiliary frame member 133 is positioned on the inner circumference side of the resin vertical frame member 132, with its engaging portion 133d engaging with the auxiliary frame member engaging portion 132i on the visible wall portion 132c of the resin vertical frame member 132, and its engaging claws 133c,133c engaging with the auxiliary frame member engaging portion 132h on the outer peripheral side surface of the visible wall portion 132d of the resin vertical frame member 132, thereby attaching it to the resin vertical frame member 132, covering the heads of the screws A32 that fix the resin vertical frame member 132, and forming a hollow portion that protrudes in the inner circumference direction.

[0053] In the vertical frame 13, with the resin vertical frame material 132 attached to the metal vertical frame material 131, the position in the depth direction of the indoor facing surface 131c of the metal vertical frame material 131 and the position in the depth direction of the indoor side surface of the attachment portion 132a of the resin vertical frame material 132 are approximately coincident, allowing the indoor sides of the metal vertical frame material 131 and the resin vertical frame material 132 to be brought into contact with and fixed to the vertical members of the building's openings, etc.

[0054] In the vertical frame 13, with the resin vertical frame material 132 attached to the metal vertical frame material 131, the visible position of the inner circumferential surface of the main body portion 131a of the metal vertical frame material 131 and the visible position of the inner circumferential surface of the resin vertical frame material 132 on the outdoor side of the visible wall portion 132c are almost identical, and the inner circumferential surface is formed without leaving a large gap between the metal vertical frame material 131 and the resin vertical frame material 132.

[0055] When the insulated door 15 is closed, the vertical frame 13 is positioned such that the position of the contact portion between the indoor side (contact surface) 131e of the metal vertical frame material 131 and the mounting portion 132a of the resin vertical frame material 132 is approximately the same as the position of the indoor side 15a of the insulated door 15, forming an insulating line that extends from the insulated door 15 to the vertical frame 13. Furthermore, on the vertical frame 13, a tight seal s13 attached to the tight seal attachment part 132j ​​abuts against the indoor side surface 15a of the insulated door 15 on the inner circumference (indoor side) of the contact portion between the indoor side surface 131e of the metal vertical frame material 131 and the mounting part 132a of the resin vertical frame material 132, forming a tight seal t13. An insulating space R3 formed of resin material is provided on the indoor side of the opposing surfaces between the insulated door 15 and the metal upper frame material 111.

[0056] (Effects of the entrance door of this embodiment) In this embodiment, the entrance door has an inner corner space formed in the frame material and the resin frame material attached in the inner corner space. This allows for a larger depth dimension of the upper frame and / or vertical frame to maintain the strength of the frame material, while aligning the insulation line formed by the resin frame material of the upper frame and vertical frame with the insulation line formed on the indoor side of the insulated door to form a continuous insulation line, thereby improving insulation performance.

[0057] In this embodiment, the entrance door has a hollow mounting section for the resin frame material, and the hollow mounting section is fitted into an inner corner space formed in the metal frame material. This makes it easy to position the resin frame material relative to the metal frame material, and also prevents misalignment, allowing for a secure attachment.

[0058] It goes without saying that the embodiments described above are not intended to limit the inventions described in the claims, but are to be treated as illustrative examples. [Explanation of Symbols]
