[0024] In the vertical frame 13, the mounting piece part 131e of the metal vertical frame member 131 is screwed to the left and right vertical members of the building opening from the outdoor side by screws (fixing means) A31, and the indoor side projected wall 131f of the metal vertical frame member 131 is screwed to the left and right vertical members of the building opening from the inner circumferential side by screws (fixing means) A32, and is fixed to the left and right vertical sides of the building opening.

[0025] As shown in Figure 3, the entrance door mullion 14 of this embodiment comprises a metal frame material 141 made of a metal material such as an aluminum alloy, a resin frame material 142 attached to the indoor side of the metal frame material 141, and a resin cover material 143 attached to the indoor side of the metal frame material 141. The mullion 14 has a fixed window 16 on its outer perimeter side and an insulated door 15 on its inner perimeter side, and a sealing material s14 is attached to the inner perimeter side of the resin frame material 142, which abuts against the vertical edge of the insulated door 15 on the outdoor side.

[0026] The left mullion 14 supports the insulated door 15 so that it can be opened and closed via a hinge 71 on the inner surface of the metal frame 141, while the right mullion 14 has a receiving bracket 72 attached to the inner surface of the metal frame 141 to receive the locking member of the insulated door 15.

[0027] As shown in Figures 1 and 3, the insulated door 15 of this embodiment is rotatably supported on the left mullion 14 by a hinge 71, and a door closer 6 is provided above the interior surface, which is in contact with the upper frame 11 to enable smooth opening and closing.

[0028] As described above, in this embodiment, the entrance door has an insulated door 15 placed in an opening formed by assembling an upper frame 11, a lower frame 12, and left and right mullions 14, 14. By placing a resin component on the indoor side of the mullion 14, the transfer of cold and heat from the metal frame material of the mullion 14 is suppressed, thereby improving the thermal insulation performance of the entrance door. The thermal insulation structure of the mullion portion of the entrance door in this embodiment will be described in more detail below. Since the mullions of the entrance door in this embodiment have the same configuration on both the left and right sides, the following description will mainly use the right-side mullion.

[0029] As shown in Figures 4 and 5, the metal frame material 141 of the entrance door mullion 14 of this embodiment has a main body portion 141a having a substantially rectangular hollow cross-section, a reinforcing arm portion 141b that is continuous with the indoor side of the main body portion 141a, and an outdoor side facing piece 141c that protrudes outward from the outdoor side of the main body portion 141a, and a pair of engaging portions 141g, 141g are provided on the indoor side surface 141h.

[0030] The main body portion 141a of the metal frame material 141 has its inner circumferential side facing the vertical side of the insulated door 15, and a panel opening 14a for holding the panel body of the fixed window 16 is formed on the outer circumferential side.

[0031] The reinforcing arm portion 141b of the metal frame material 141 has a recessed wall portion 141d extending in the inward direction from the outer peripheral end of the indoor surface of the main body portion 141a, and an indoor-facing wall portion 141e extending in the inward direction from the recessed wall portion 141d, forming a recess on the indoor side of the main body portion 141a. The formation of the reinforcing arm portion 141b on the indoor side of the main body portion 141a improves the overall strength of the metal frame material 141.

[0032] The metal frame material 141 has a trim engagement portion 141f on the outer circumference side of the recessed wall portion 141d of the reinforcing arm portion 141b, and the trim 144 engaged with the trim engagement portion 141f and the outdoor-side facing piece 141c form a panel opening 14a that holds the panel body of the fixed window 16.

[0033] The resin frame material 142 of the entrance door mullion 14 in this embodiment has a mounting portion 142a having a hollow section, a recessed wall portion 142d having a hollow cross-sectional shape that extends inward from the mounting portion 142a, and a visible wall portion 142c that extends inward from the recessed wall portion 142d, and a sealing material mounting portion 142j that opens to the outside is provided on the visible wall portion 142c.

[0034] The resin frame material 142 is provided with engaging portions 142f and 142g on the outer and inner sides of the hollow portion of the mounting portion 142a, respectively. The resin vertical frame material 132 may, if necessary, be provided with an engaging portion 142h for attaching the cover material 143 to the indoor side of the visible wall portion 142c.

[0035] The resin frame material 142 is attached to the indoor side of the metal frame material 141 by bringing the outdoor side of the mounting portion 142a into contact with the indoor side 141h of the metal frame material 141, and engaging the engaging portions 142f and 142g with a pair of engaging portions 141g and 141g of the metal frame material 141.

[0036] The cover material 143 of the entrance door mullion 14 in this embodiment has a central portion 143a with a pair of engaging claws 143d, 143d formed on the outdoor side of a single rectangular hollow section, an outer peripheral portion 143b provided on the outer periphery of the central portion 143a with a plurality of hollow sections arranged in the direction of depth, and an inner peripheral portion 143c that extends inward from the inner peripheral end of the central portion 143a and then bends outward to form an outer peripheral portion.

[0037] The cover material 143 is attached to the metal frame material 141 by engaging the engaging claws 143d, 143d provided on the outdoor side of the central part 143a with the indoor-facing wall portion 141e of the reinforcing arm portion 141b of the metal frame material 141. Furthermore, the cover material 143 may be provided with an engaging portion 143e at the outdoor end of its inner circumference portion 143c, and the engaging portion 143e may be engaged with a receiving portion 142h provided on the indoor side of the visible wall portion 142c of the resin frame material 142. This allows the mullion 14 to be positioned on the indoor side without rattling.

[0038] In the mullion 14, with the resin frame material 142 attached to the metal frame material 141, the visible position of the inner circumferential surface of the main body portion 141a of the metal frame material 141 and the visible position of the inner circumferential surface of the resin frame material 142 on the outdoor side of the visible wall portion 142c are almost identical, and the inner circumferential surface is formed without leaving a large gap between the metal frame material 141 and the resin frame material 142.

[0039] In the mullion 14, on the inner circumference side of the contact portion between the indoor side surface 141h of the metal frame material 141 and the mounting portion 142a of the resin frame material 142, a tight portion t14 is formed when a tight material s14 attached to the tight material mounting portion 142j contacts the indoor side surface 15a of the insulated door 15, and an insulated space R4 formed of resin material is provided on the indoor side of the opposing surfaces between the insulated door 15 and the metal frame material 141.

[0040] When the insulated door 15 is closed, the mullion 14 is positioned such that the position in the depth direction of the contact portion (surface) between the indoor side (contact surface) 141h of the metal frame material 141 and the mounting portion 142a of the resin frame material 142 almost coincides with the position in the depth direction of the indoor side 15a of the insulated door 15 at the tight portion t14 between the mullion 14 and the insulated door 15, forming an insulation line that extends from the insulated door 15 to the mullion 14.

[0041] (Effects of the entrance door of this embodiment) In this embodiment, the entrance door aligns the position in the depth direction of the contact portion between the metal frame material and resin frame material of the mullion that is placed inside the frame and supports the insulated door with the position in the depth direction of the indoor side surface of the insulated door. This aligns the insulation line of the entrance door with the indoor side surface of the insulated door, reducing the amount of metal protruding into the room and improving insulation performance.

[0042] In this embodiment, the entrance door is provided with reinforcing arms that extend inward on the indoor side of the metal frame material of the mullion, which is positioned within the frame and supports the insulated door. This allows the strength to be maintained without increasing the cross-sectional area of ​​the main body of the mullion, and improves the insulation performance by aligning the insulation line formed at the contact portion between the metal frame material and the resin frame material with the indoor side of the entrance door.

[0043] The cover material 143, attached to the indoor side of the mullion 14, has a central portion 143a that covers the indoor side of the main body portion 141a and reinforcing arm portion 141b of the metal frame material 141, while the outer peripheral portion 143b is positioned on the indoor side of the panel opening 14a of the fixed window 16. This suppresses the transfer of cold and heat from the metal frame material 141 and improves the aesthetic appearance.

[0044] 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]
