  A door such as the above-described heat-insulating metal door requires a highly rigid member such as the door frame member in order to provide a handle, a locking mechanism, or the like on the door end side. Such door frame materials are generally made of metal such as iron, but like the above-described heat-insulating metal door, the door frame material covers the entire circumference between the door surface material and the door back surface material. In the case where it is provided, there is a problem that heat conduction on the front and back sides occurs in the door frame material and it is difficult to obtain high heat insulation performance.

  This invention is made | formed in view of this subject, The place made into the objective is to provide the door with higher heat insulation performance, and the fitting provided with this door.

  In order to achieve such an object, the door of the present invention is a door provided with an opening that opens and closes to communicate indoors and outdoors, and a core disposed on the outdoor side between two surface materials forming the front and back surfaces. A material, a vacuum heat insulating material facing the core material on the indoor side, a metal reinforcing material covering the outer peripheral surface of the core material, and the reinforcing material and the prospective direction on the outer peripheral side of the vacuum heat insulating material And a synthetic resin-made peripheral end member arranged side by side.

  According to such a door, since the metal reinforcing material covering the outer peripheral surface of the core material is provided on the outer periphery of the core material, the door does not have a frame material surrounding the entire periphery of the door. The necessary handle and locking mechanism on the outer peripheral side can be arranged on the core material side and attached to the reinforcing material. In addition, it is possible to place the vacuum insulation material on almost the entire surface of the door by arranging the locking mechanism attached to the reinforcing material covering the outer peripheral surface of the core material on the core material side so as not to reach the vacuum insulation material side. is there. For this reason, it is possible to provide higher heat insulation performance. At this time, since the vacuum heat insulating material is provided so as to face the core material, the exterior material of the vacuum heat insulating material is hardly damaged by the core material. For this reason, it is possible to provide a door that can be easily provided on the indoor side with a vacuum heat insulating material having high heat insulating properties. Furthermore, since a synthetic resin peripheral end member is provided on the indoor side of the metal reinforcing material, heat conduction to the indoor side by the reinforcing material can be suppressed. For this reason, it is possible to provide the door which has higher heat insulation performance.

In this door, it is preferable that the peripheral end member has an engaging portion that engages with the reinforcing material.
According to such a door, since the peripheral end member includes the engaging portion that engages with the reinforcing member, the peripheral end member can be more reliably disposed on the indoor side of the reinforcing member.

In such a door, the core material is preferably a heat insulating material.
According to such a door, since the core located outside the vacuum heat insulating material is also a heat insulating material, it is possible to provide a door with higher heat insulating performance.

  The indoor cover includes: a frame that forms the opening; and a synthetic resin indoor cover member that covers a metal portion disposed on the indoor side of the frame from the inner peripheral side of the opening. The member is a joinery that is provided at a distance from each other, and has two sealing materials that abut each of the peripheral end members in a state where the door closes the opening. .

  According to such a joinery, in a state where the door closes the opening formed by the frame body, the two sealing materials provided on the indoor cover member at a distance from each other are made of a synthetic resin that the door has. It abuts on the peripheral end member. For this reason, the synthetic resin indoor cover member included in the frame body and the synthetic resin peripheral end member included in the door are connected by the two sealing materials spaced apart from each other. That is, a space surrounded by the synthetic resin is formed between the frame body and the door by the indoor cover member, the peripheral end member, and the two sealing materials. For this reason, it is possible to provide a fitting with higher heat insulation performance.

At this time, the facing wall portion 14a on the indoor side of the reinforcing member 14 is disposed so as not to protrude to the inner peripheral side from the inner peripheral side edge of the peripheral end main body portion 16a. Here, a synthetic resin member covering the outer peripheral surface of the vacuum heat insulating material 13, that is, the base material peripheral end member 16 and the peripheral end inner cover 17 correspond to the peripheral end member. Moreover, since the base material peripheral edge material 16 engages with the reinforcing material 14 by the connection part cover part 16b and the outer extension part 16c, the connection part cover part 16b and the outer extension part 16c correspond to an engagement part.

  The reinforcing material 14 and the base material peripheral edge material 16 are formed in a frame shape, and a vacuum heat insulating material 13 is arranged inside thereof, and a surface material 18 that forms an outdoor side surface and an indoor side surface is attached to form a panel shape having a space inside. It is formed. At this time, the end portions of each surface material 18 are extended to the center side in the thickness direction of the door 10 in the four directions of the reinforcing material 14 and the base material peripheral end material 16, and screws (not shown) or rivets (not shown) from the outer peripheral side.

A synthetic resin sealing material 29 is provided on the lower door portion 22b so as to protrude outward. For this reason, when the door 10 is closed, the inner peripheral cover 17 made of synthetic resin and the sealing material 29 provided at the lower end of the door 10 come into contact with each other, and the outer peripheral cover 15 made of aluminum and the aluminum cover 15 are made of aluminum. There is no contact with the lower frame 22. In other words, the outer peripheral end cover 15 and the lower frame 22 are thermally insulated by the inner peripheral end cover 17 and the sealing material 29.

  The upper frame 21 and the left and right vertical frames 23 are formed by connecting outer frame members 21a and 23a made of a metal, for example, an aluminum extruded member, and inner frame members 21b and 23b via synthetic resins 21c and 23c. ing. The outer frame members 21 a and 23 a face the substantially outer peripheral surface of the door 10 when the door 10 is closed, and the inner frame members 21 b and 23 b are arranged on the indoor side of the closed door 10. Moreover, the inner frame members 21b and 23b cover the inner frame members 21b and 23b on the inner peripheral side of the frame body 2 and project to the inner peripheral side of the frame body 2 to form a door stop. Synthetic resin door holding members 25 and 26 are provided.

  A seal member 29 is provided on the door holding member 25 of the upper frame 21 so as to protrude outward. Therefore, when the door 10 is closed, the synthetic resin-made peripheral end inner cover 17 and the sealing material 29 provided at the upper end of the door 10 come into contact with each other, and the aluminum peripheral end outer cover 15 and the aluminum-made cover 15 are made of aluminum. There is no contact with the inner frame member 21b. That is, the outer peripheral end cover 15 and the inner frame member 21 b are thermally insulated by the peripheral end inner cover 17 and the sealing material 29.

  The door holding members 26 of the left and right vertical frames 23 are projected to the inner peripheral side of the frame body 2 at the outer end of the portion covering the inner frame member 23 b and also protruded to the inner peripheral side of the frame body 2. Each of the sealing materials 30 is provided so as to protrude outward from the portion of the door 10 facing the indoor side surface of the closed door 10. For this reason, when the door 10 is closed, the synthetic resin-made peripheral end inner cover 17 and the two sealing members 30 provided at the left and right ends of the door 10 come into contact with each other, so that the aluminum peripheral end outer cover 15 is made. And the inner frame member 23b made of aluminum are not in contact with each other. That is, the outer peripheral end cover 15 and the inner frame member 23 b are thermally insulated by the peripheral end inner cover 17 and the sealing material 30. In addition, since the two sealing members 30 provided on the door holding member 25 of the left and right vertical frames 23 are spaced apart from each other, when the door 10 is closed, the door 10 and the vertical frame 23 A space S surrounded by the two sealing materials 30, the inner circumferential end cover 17 and the door-holding member 25 is formed. This space S further improves heat insulation.

  According to the door 10 and the fitting 1, since the metal reinforcing material 14 that covers the outer peripheral surface 12 a of the core member 12 is provided on the outer periphery of the core member 12, a frame that surrounds the entire periphery of the door 10. Even if a material or the like is not provided, it is possible to provide the reinforcing material 14 with a latch mechanism 10a and a locking mechanism 10b necessary for the door tip side, a hinge (not shown) necessary for the hanging base side, and the like. Moreover, since the vacuum heat insulating material 13 is provided in the prospective direction on the indoor side of the core material 12, it is possible to provide higher heat insulating properties.

  At this time, the vacuum heat insulating material 13 is provided so as to face the core material 12, and the facing wall portion 14 a on the indoor side of the reinforcing material 14 is located closer to the inner peripheral side than the inner peripheral side edge of the peripheral end main body portion 16 a. Since it is formed so as not to protrude, the packaging material of the vacuum heat insulating material 13 is hardly damaged. For this reason, it is possible to provide the door 10 which can equip the indoor side of the core material 12 with the vacuum heat insulating material 13 with high heat insulation easily. Further, since the base material peripheral end material 16 made of synthetic resin is provided on the indoor side of the iron reinforcing material 14, heat conduction to the indoor side by the reinforcing material 14 can be suppressed. For this reason, it is possible to provide the door 10 and the fitting 1 which have higher heat insulation.

Further, the base material peripheral end member 16 includes a connecting portion cover portion 16b that covers the connecting portion 14b of the reinforcing member 14 on the outer peripheral side, and an outer extending portion 16c that extends outward from the outdoor end of the connecting portion cover portion 16b. Since it engages with the reinforcing material 14, it is possible to more reliably arrange the base material peripheral end material 16 on the indoor side of the reinforcing material 14.
Moreover, since the core material 12 is heat insulation materials, such as urethane foam, it is possible to provide the door 10 and the fitting 1 with higher heat insulation.

  Further, in a state where the door 10 closes the opening 2 a formed by the frame body 2, the two sealing members 30 provided at intervals on the synthetic resin door-holding member 25 are combined with each other. It abuts on the resin base material peripheral end material 16. For this reason, the door holding member 25 on the frame body 2 side and the base material peripheral end member 16 on the door 10 side are connected by the two sealing materials 30 spaced apart from each other. That is, a space S surrounded by the synthetic resin is formed between the frame body 2 and the door 10 by the door holding member 25, the base material peripheral end material 16, and the two sealing materials 30. For this reason, it is possible to provide the fitting 1 with higher heat insulation performance.
