[Brief explanation of the drawing]
[0007] [Figure 1] This is a cross-sectional view of a door according to an embodiment of the present invention, cut at position AA shown in Figure 2. [Figure 2] This is a front view of a door according to an embodiment of the present invention, seen from one side. [Figure 3] This is a front view of the door according to an embodiment of the present invention, with the other side surface material removed, as seen from the other side. [Modes for carrying out the invention]
[0008] Embodiments of the present invention will be described below with reference to the attached drawings. As shown in Figures 1 and 2, the door 1 comprises a door 3, a reinforcing member 5, and a door closer 7. The door 1 is installed at an entrance to the building, and the door 3 is installed so as to open outwards (to the other side) relative to a door frame 9 attached to an opening in the building's structure. As shown in Figure 2, the door frame 9 is framed by an upper frame 11, a hinge frame 13, and a door edge frame 15.
[0009] As shown in Figure 3, the door 3 comprises a frame body 27 surrounded by an upper frame 19, a lower frame 21, a hinge frame 23, and a door edge frame 25, a one-sided surface material 29 (see Figure 1) attached to the interior side of the frame body 27, and a other-sided surface material 31 (see Figure 1) attached to the exterior side of the frame body 27. The surface material 29 on one side and the surface material 31 on the other side are spaced apart, with the frame body 27 in between them. Between the surface material 29 on one side and the surface material 31 on the other side, the inner circumference of the frame body 27 is filled with insulating material 33. The insulating material 33 is a honeycomb material made of resin. The insulation material 33 is fixed to the surface material 29 on one side and the surface material 31 on the other side with adhesive.
[0010] As shown in Figure 1, the reinforcing member 5 is provided between the one-sided surface material 29 and the other-sided surface material 31 and is fixed to the one-sided surface material 29 and the other-sided surface material 31. The reinforcing member 5 comprises a surface material fixing portion 35 on one side, a surface material fixing portion 37 on the other side, and a connecting portion 39 that connects the surface material fixing portion 35 on one side and the surface material fixing portion 37 on the other side. In this embodiment, the reinforcing member 5 is formed in a substantially U-shape by the surface material fixing portion 35 on one side, the connecting portion 39, and the surface material fixing portion 37 on the other side. The surface material fixing portion 35 on one side and the surface material fixing portion 37 on the other side have the same width dimension W (see Figure 3) along the width direction of the door 3, but the vertical dimension H1 of the surface material fixing portion 35 is larger than the vertical dimension H2 of the surface material fixing portion on the other side. Therefore, the area of the surface material fixing portion 35 on one side is larger than the area of the surface material fixing portion 37 on the other side. In this embodiment, the vertical dimension H1 of the one-sided surface material fixing portion 35 is at least twice the vertical dimension H2 of the other-sided surface material fixing portion.
[0011] One surface material fixing part 35 is fixed to the other side surface of the one surface material 29 with adhesive, and the other surface material fixing part 37 is fixed to the one side surface of the other surface material 31 with adhesive. The adhesive used to bond each surface material fixing part 35 and 37 to the corresponding surface materials 29 and 31 is the same type of adhesive used to bond the heat insulating material 33 to each surface material 29 and 31. One side surface material fixing portion 35 has a total of four screw holes 36 (see Figure 3) into which the screws 49 described later are screwed.
[0012] As shown in Figure 2, the door closer 7 has essentially the same configuration as conventional models, so a detailed description of its structure is omitted. It is installed on one side (the interior side) of the door 3 and comprises a main body 40, a rotating shaft 41 provided on the main body 40, a door mounting portion 43 attached to the door 3, a bracket 45 fixed to the upper frame 11, and a link mechanism 47 provided between the bracket 45 and the rotating shaft 41. The main body 40 incorporates a damper and spring that utilize the viscosity of the fluid (oil). When the door 3 is opened and released, a rotating shaft 41 on the main body 40 slowly rotates, causing the door 3 to close slowly and automatically.
[0013] The door attachment portions 43 project from the left and right sides of the main body 40 respectively, and as shown in FIG. 1, are stepped portions thinner than the main body 40. Two screw insertion holes 48 are formed vertically in each door attachment portion 43, and the door closer 7 is fixed to the door 3 by screws 49 inserted through the screw insertion holes 48. Each screw 49 is inserted through the screw insertion hole 48 of the door attachment portion 43 and the screw insertion hole 38 of one side surface member 29, and is screwed into the screw hole 36 of the one side surface member fixing portion 35 of the reinforcing member 5.
[0014] As shown in FIG. 2, the link mechanism 47 includes a door-side arm 51, a frame-side arm 53, and a connecting portion 55 that connects the door-side arm 51 and the frame-side arm 53. One end portion 51a of the door-side arm 51 is fixed to the rotation shaft 41 of the door closer main body 40, and the other end portion 51b is rotatably connected to the connecting portion 55. One end 53a of the frame-side arm 53 is rotatably connected to the bracket 45, and the other end 53b is rotatably connected to the connecting portion 55. In addition, in FIG. 1, only the door 3 is shown, so the bracket 45 fixed to the upper frame 11 and the frame-side arm 53 are not described.
[0015] Next, a method for manufacturing the door 1 will be described. First, the door 3 is manufactured. As shown in FIG. 3, the door 3 has one side surface member 29 (see FIG. 1) pasted on one side (indoor side) of the framed frame body 27, and the reinforcing member 5 is arranged on the other side surface of the one side surface member 29 on the inner peripheral side of the upper frame frame 19, and the one side surface member fixing portion 35 of the reinforcing member 5 is fixed to the one side surface member 29 with an adhesive. Next, the heat insulating material 33 is fixed to the other side surface of the one side surface member 29 and the other side surface of the one side surface member fixing portion 35 of the reinforcing member 5 with an adhesive respectively. Note that the heat insulating material 33 is not provided in the space S (see FIG. 1) between the one side surface member fixing portion 35 and the other side surface member fixing portion 37 of the reinforcing member 5. After that, an adhesive is applied to the other side surface (outdoor side surface) of the frame body 27, the other side surface of the other side surface material fixing portion 37 of the reinforcing member 5, and the other side surface of the heat insulating material 33, and the other side surface material 31 is attached to the other side surface of the frame body 27. In addition, a screw insertion hole 38 (see FIG. 1) is formed in the one side surface material 29 at a position corresponding to the screw hole 36 of the reinforcing member 5.
[0016] Next, referring to FIG. 1, the attachment of the door closer 7 will be described. The main body 40 of the door closer 7 is arranged on the one side surface material 29 of the door 3, and the screw insertion hole 48 of the door attachment portion 43 is aligned with the screw insertion hole 38 of the one side surface material 29. Then, the screw 49 is inserted through the screw insertion holes 48 and 38 and screwed into the screw hole 36 of the reinforcing member 5 to fix the door closer main body 40 to the door 3. After that, as shown in FIG. 2, the link mechanism 47 is attached between the bracket 45 attached to the upper frame 11 and the rotation shaft 41 of the main body 40.
[0017] Next, the operation and effect of this embodiment will be described. As shown in FIG. 1, the reinforcing member 5 for fixing the door closer 7 is provided between the one side surface material 29 and the other side surface material 31 and is fixed to the one side surface material 29 and the other side surface material 31 respectively, so that the fixing strength of the door closer 7 to the door 3 can be increased.
[0018] Since the reinforcing member 5 is composed of a one side surface material fixing portion 35, an other side surface material fixing portion 37, and a connecting portion 39 connecting these, the structure of the reinforcing member 5 can be simplified and the manufacture of the reinforcing member 5 is easy. Since the one side surface material fixing portion 35 and the other side surface material fixing portion 37 of the reinforcing member 5 are fixed to the corresponding surface materials 29 and 31 with an adhesive, the reinforcing member 5 can be easily attached to the door 3. Since the adhesive uses the same type of adhesive as the adhesive of the heat insulating material 33 filled between the one side surface material 29 and the other side surface material 31 of the door 3, the types of materials used in the manufacture can be reduced.
[0019] Since the area of the surface material fixing portion 35 on one side of the reinforcing material 5 that secures the door closer 7 is larger than the area of the surface material fixing portion 37 on the other side, the door closer 7 can be firmly fixed and the amount of material required for the reinforcing material 5 can be reduced. Except for the space S between the surface material fixing portion 35 on one side and the surface material fixing portion 37 on the other side of the reinforcing material 5, the insulating material 33 is also placed in the area where the reinforcing material 5 is located, so high thermal insulation can be obtained even with the reinforcing material 5 in place.
[0020] The present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the spirit of the invention. The reinforcing member 5 is not limited to being formed in a roughly U-shape with a surface material fixing portion 35 on one side, a surface material fixing portion 37 on the other side, and a connecting portion 39. It may also be H-shaped, or two connecting portions 39 may be provided between the surface material fixing portion 35 on one side and the surface material fixing portion 37 on the other side to form a rectangle.
