[0007] The embodiments of the present invention will now be described based on the drawings. Figures 1 to 4 show one embodiment of the opening device of the present invention. This opening device is applied to an entrance door installed at the entrance of a building such as a wooden house, and as shown in Figures 1 and 2, it comprises a frame 13 installed in the opening of the building's structure, and a door 1 attached to the frame 13 by hinges 14 and provided to open outwards. Frame 13 is constructed by framing the upper frame 15, the lower frame 16, and the left and right vertical frames 2,2. As shown in Figure 3, door 1 is equipped with a handle 17 on the leading edge side, a latch lock that is linked to the handle 17, and deadbolts 18a and 18b located above and below the handle 17. The door is locked by engaging the latch lock and deadbolts 18a and 18b with a lock receiver provided on the vertical frame 2. A door closer 19 is provided on the upper part of the interior side of door 1.

[0008] As shown in Figure 1, the vertical frame 2 is composed of a metal frame material 7 located on the exterior side and a resin frame material 8 located on the interior side, and is designed to provide thermal insulation. The metal frame material 7 is formed from an extruded aluminum alloy profile and, as shown in Figure 4, has a hollow portion 20 with a roughly rectangular cross-section and nailing fins 21 that are formed on the indoor end and project outward, and are fixed with screws (not shown) to the outdoor surface of the building structure 11. The metal frame material 7 has a recess 22 formed on its interior side, and a groove 23 formed on the inner circumference side of the recess 22 into which the reinforcing material 10, described later, engages. Furthermore, on the interior side of the metal frame material 7, which is on the inner circumference side of the recess 22, a T-shaped engaging portion 24 and a groove-shaped engaging portion 25 are formed spaced apart in the inward and outward directions for connecting with the resin frame material 8. A water-sealing material 26 is provided on the interior side of the T-shaped engaging portion 24.

[0009] The resin frame material 8 is formed from an extruded resin profile and, as shown in Figure 4, has a main body portion 27 with a rectangular cross-section extending in the indoor-outdoor direction, a connecting portion 28 between the main body portion 27 and the metal frame material 7 provided on the outdoor side of the main body portion 27, and a door stop portion 29 that protrudes from the inner circumference side of the main body portion 27. The main body 27 has a partition 30 inside, forming multiple hollow sections 31 arranged in the direction of the interior and exterior. The connecting portion 28 consists of two projections 32 and 33 that protrude from the main body portion 27 toward the outside. The projection 32 on the inner circumference has a tip 32a that is bent toward the outer circumference in a hook shape, and this tip 32a engages with the T-shaped engaging portion 24 of the metal frame material 7. The projection 33 on the outer circumference has a tip 33a that engages with the groove-shaped engaging portion 25 of the metal frame material 7. Thus, the metal frame material 7 and the resin frame material 8 are connected by engagement from both the indoor and outdoor directions. A sealing material 34 is attached to the door stopper 29 facing outwards, and the sealing material 34 is in contact with the interior side surface of the door 1. A heat-expanding material 35 is provided on the inner circumference of the main body 27 on the exterior side of the door stopper 29. An airtight seal 9 is attached to the exterior end of the inner side surface of the resin frame material 8. The airtight seal 9 is in contact with the interior end of the edge material 6 attached to the leading edge surface of the door 1.

[0010] As shown in Figure 4, the metal frame material 7 and the resin frame material 8 are connected by reinforcing members 10 provided on the outer periphery. The reinforcing members 10 are formed by press-forming a metal plate such as steel, and are formed in a roughly T-shape in plan view with a visible surface portion 36 and an internal surface portion 37. Multiple reinforcing members 10 are provided at intervals along the longitudinal direction of the vertical frame 2. The visible surface portion 36 is fixed by engaging its inner edge with the inner groove 23 of the recess 22 of the metal frame material 7, and contacting the indoor side surface of the recess 22 with screws 38 from the indoor side. The visible surface portion 37 is fixed by contacting the outer surface of the main body portion 27 of the resin frame material 8 with screws 39 from the outer side. The vertical frame 2 is constructed by connecting the metal frame material 7 and the resin frame material 8 with a reinforcing member 10, and then fixing the main body portion 27 of the resin frame material 8 closer to the interior side to the building structure 11 with a screw 12 that passes through the reinforcing member 10. The resin frame material 8 has a cover material 40 attached to the interior side of the door stop 29, and the through-hole 41 for the screw 12 is hidden by the cover material 40.

[0011] Figures 5-1 and 5-2 show the assembly procedure for the vertical frame 2. First, as shown in Figure 5-1(a), the tip 32a of the projection 32 on the inner circumference side of the resin frame material 8 is engaged with the T-shaped engaging portion 24 of the metal frame material 7. Rotating with the engaging portion 24 as a pivot point, the tip 33a of the projection 33 on the outer circumference side of the resin frame material 8 is engaged with the groove-shaped engaging portion 25 of the metal frame material 7, thereby connecting the metal frame material 7 and the resin frame material 8. Next, as shown in Figure 5-1(b), the visible surface portion 36 of the reinforcing member 10 is engaged with the groove 23 on the inner circumference side of the recess 22 of the metal frame material 7, and the visible surface portion 36 is fixed to the metal frame material 7 with screws 38 from the indoor side. Next, as shown in Figure 5-2(c), the visible surface portion 37 of the reinforcing material 10 is fixed to the main body portion 27 of the resin frame material 8 with screws 39 from the outer circumference. Subsequently, the vertical frame 2 is framed with the upper frame 15 and the lower frame 16, and the framed frame 13 is placed into the opening of the building structure from the outside. Then, as shown in Figure 5-2(d), the indoor side of the resin frame material 8 is fixed to the building structure 11 with screws 12 that pass through the reinforcing material 10.

[0012] As shown in Fig. 2, the upper frame 15 is composed of a metal frame member 7 located on the outdoor side and a resin frame member 8 located on the indoor side, similar to the vertical frame 2 described above. The metal frame member 7 and the resin frame member 8 are connected by a reinforcing member 10 on the outer peripheral side, and the indoor side of the resin frame member 8 is fixed to the housing 11 with screws 12 passing through the reinforcing member 10.

[0013] Figs. 6-1 and 6-2 show the assembly procedure of the upper frame 15. First, as shown in Fig. 6-1(a), the tip 32a of the protruding piece 32 on the inner peripheral side of the resin frame member 8 is engaged with the engaging portion 24 on the inner peripheral side of the metal frame member 7, and rotated around the engaging portion 24 as a fulcrum, so that the tip 33a of the protruding piece 33 on the outer peripheral side of the resin frame member 8 is engaged with the groove-shaped engaging portion 25 of the metal frame member 7, thereby connecting the metal frame member 7 and the resin frame member 8. Next, as shown in Fig. 6-1(b), the locating surface portion 36 of the reinforcing member 10 is engaged with the groove 23 of the metal frame member 7, and the locating surface portion 36 is fixed to the metal frame member 7 with screws 38 from the indoor side. Next, as shown in Fig. 6-2(c), the expected surface portion 37 of the reinforcing member 10 is fixed to the main body portion 27 of the resin frame member 8 with screws 39 from the outer peripheral side. After that, the upper frame 15, the lower frame 16, and the vertical frame 2 are framed, and the framed frame 13 is placed into the housing opening from the outdoor side. Then, as shown in Fig. 6-2(d), the indoor side of the resin frame member 8 is fixed to the housing 11 with screws 12 passing through the reinforcing member 10.

[0014] In this way, in this opening device, the reinforcing member 10 is provided on the outer peripheral sides of the vertical frame 2 and the upper frame 15 across the metal frame member 7 and the resin frame member 8, and the reinforcing member 10 is screwed to the metal frame member 7 and the resin frame member 8 respectively, so that the metal frame member 7 and the resin frame member 8 are firmly connected. Moreover, since the indoor side of the resin frame member 8 is fixed to the housing 11 with screws 12 passing through the reinforcing member 10, the metal frame member 7 is connected to the housing 11 through the reinforcing member 10, thus restricting the movement and rotation of the metal frame member 7. As a result, this opening device can form the indoor sides of the vertical frame 2 and the upper frame 15 with the resin frame member 8 to enhance the heat insulation performance while having high strength.

[0015] As shown in FIGS. 1 and 2, the door 1 is configured by arranging aggregates 42 in a frame shape around its perimeter, disposing a heat insulating material 43 formed of styrofoam or the like inside thereof, and attaching an outdoor side member 3 and an indoor side member 4 made of steel plates to the outdoor side and the indoor side, respectively. As shown in FIG. 4, the aggregate 42 is formed of a resin aggregate 42a having a substantially U-shaped cross section and a substantially U-shaped metal aggregate 42b provided on the inner peripheral side thereof. The outdoor side member 3 and the indoor side member 4 cover the mating surface of the aggregate 42, and the edge portions on the four sides are bent along the prospective surface of the aggregate 42 to form bent portions 5a and 5b, and the bent portions 5a and 5b are fixed to the aggregate 42 with rivets 44.

[0016] As shown in FIG. 4, an edge member 6 made of an extruded aluminum alloy material is attached along the longitudinal direction on the prospective surface of the door tip side of the door 1. The edge member 6 has a protrusion 45 protruding to the outer peripheral side at the indoor side end, and a packing 46 is held on the inner peripheral side of the protrusion 45. Further, the edge member 6 has a smoke return 47 for hiding the gap between the door 1 and the vertical frame 2 from the outdoor side, and a tight material 48 is provided on the indoor side of the smoke return 47 so as to abut against the outdoor side surface of the vertical frame 2. The bent portion 5b of the indoor side member 4 extends to a position hidden by the edge member 6 and is spaced apart from the edge member 6.

[0017] In this way, in this opening device, the indoor side of the vertical frame 2 is formed of a resin frame member 8, the airtight material 9 attached to the resin frame member 8 abuts against the edge member 6 of the door 1, and the bent portion 5b of the indoor side member 4 of the door 1 extends to a position hidden by the edge member 6 and is spaced apart from the edge member 6, so that the heat transfer between the indoor and outdoor through the vertical frame 2 is suppressed, and the heat transfer between the indoor and outdoor through the edge member 6 and the indoor side member 4 of the door 1 is suppressed. Furthermore, the airtight material 9 can prevent cold air from entering the room through the gap between the vertical frame 2 and the door 1, so that high heat insulation performance can be exhibited. In addition, this opening device covers the prospective surface of the door tip side of the door 1 with the edge member 6 which is a metal material and the bent portion 5b of the indoor side member 4, so that it takes into account the fire prevention performance in addition to the heat insulation performance. Furthermore, in the event of a fire, the heat-expandable material 35 (see Figure 4) provided on the vertical frame 2 expands due to the heat of the fire, filling the space between the airtight material 9 and the sealing material 34. The heat-expandable material 49 (see Figure 2) provided on the upper frame 15 and lower frame 16 also expands due to the heat of the fire, filling the gap between the door 1 and the upper and lower frames 15 and 16 from the interior side. This prevents flames from passing between the frame 13 and the door 1.

[0018] As described above, this opening device comprises a door 1 and a vertical frame 2. The door 1 has an interior side panel 4 and an edge panel 6 located on the interior side. The interior side panel 4 has a bent portion 5b at its outer edge that is bent outwards. The bent portion 5b extends to a position where it is hidden by the edge panel 6 and is spaced apart from the edge panel 6. The vertical frame 2 has a metal frame 7 located on the exterior side and a resin frame 8 located on the interior side. The resin frame 8 has an airtight seal 9, and the airtight seal 9 is in contact with the edge panel 6 (see Figure 4), which improves thermal insulation. Furthermore, the fact that the bent portion 5b of the interior side panel 4 extends to a position where it is hidden by the edge panel 6 improves fire resistance.

[0019] This opening device includes a vertical frame 2, which has a metal frame material 7 located on the exterior side and a resin frame material 8 located on the interior side. A reinforcing member 10 is provided on the outer circumference of the vertical frame 2, spanning both the metal frame material 7 and the resin frame material 8. The reinforcing member 10 is screwed to the metal frame material 7 and the resin frame material 8, respectively, connecting the metal frame material 7 and the resin frame material 8. The interior side of the resin frame material 8 is fixed to the building structure 11 with screws 12 that pass through the reinforcing member 10 (see Figure 4). This improves thermal insulation and increases strength with the reinforcing member 10. This opening device, like the vertical frame 2, consists of a metal frame 7 located on the exterior side and a resin frame 8 located on the interior side. The metal frame 7 and the resin frame 8 are connected by a reinforcing member 10, and the interior side of the resin frame 8 is fixed to the building structure 11 with screws 12 that pass through the reinforcing member 10 (see Figure 2), thereby further enhancing the thermal insulation performance and strength. The metal frame material 7 and the resin frame material 8 are connected by engagement from both the indoor and outdoor directions (see Figures 5-1 and 6-1), resulting in good assembly.

[0020] The present invention is not limited to the embodiments described above. The cross-sectional shapes of the metal frame material and the resin frame material can be changed as appropriate. The shape and material of the reinforcing material can be changed as appropriate. The present invention can be applied to any opening device having a door. Furthermore, the present invention is not limited to residential use but can also be applied to non-residential use (e.g., warehouses, etc.). [Explanation of symbols]
