DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] An opening device according to one embodiment will be described with reference to the drawings, taking as an example an entrance door decorated with a plurality of decorative moldings attached in a left-right line to the exterior side surface. (Overall composition) As shown in FIG. 1, the entrance door of this embodiment is an entrance door having a door body 1 arranged at an entrance or other entrance of a building and having a plurality of vertically long decorative moldings 5, 5 attached side by side on the exterior side of the door body 1.

[0010] The door body 1 constituting the front door is formed by arranging plate materials 1a, 1b such as steel plates inside and outside a core material 11 made of resin or the like arranged on all four sides (top, bottom, left, right), as shown in Figure 2(a), and arranging a heat insulating material 1c made of a foam plate material or the like between the plate materials 1a, 1b. The door body 1 has a vertical member 16 made of a metal material such as an aluminum alloy attached to the vertical side on the door tip side, and is supported by a hinge 81 (FIG. 1) on the vertical side on the hanging side so that it can be opened and closed freely.

[0011] The front door has multiple decorative moldings 5, 5 arranged in the left-right direction on the exterior side of the door body 1, i.e., the exterior side of the exterior panel material 1b, and is attached to the exterior side of the door body 1 by an adhesive means such as double-sided tape.

[0012] (Structure of cosmetic mall) As shown in FIG. 4, the decorative molding 5 of the front door of this embodiment includes a molding material 51 made of a metal material such as an aluminum alloy, and end caps 6 made of a resin material that close the upper and lower ends of the molding material 51.

[0013] As shown in Figures 2(b), 3(a), and 4, the molding material 51 is a vertically long component that has an exterior decorative wall 51a that has a cross-sectional shape with two peaks toward the exterior and with the central portion in the left-right direction concave toward the interior of the room, left and right side walls 51b, 51b extending toward the interior of the room from both the left and right sides of the decorative wall 51a, and left and right mounting walls 51c, 51c extending toward each other from the interior ends of the left and right side walls 51b, 51b. The molding material 51 may have double-sided tape 511 attached in advance to the indoor side surfaces of the left and right mounting walls 51c, 51c.

[0014] The decorative molding 5 has resin end caps 6 attached to the upper and lower ends of the molding material 51, and is attached to the door body 1 by adhering the left and right mounting walls 51c, 51c of the molding material 51 to the exterior side surface of the door body 1 with double-sided tape or the like.

[0015] As described above, the decorative molding 5 is attached by adhesion to the exterior side of the door body 1, but the front door of this embodiment further has a fixing part 7 provided on the door body 1, and the decorative molding 5 is supported by this fixing part 7, which ensures that the decorative molding 5 is fixed to the door body 1 and makes it easy to manufacture a front door with the decorative molding 5. The configuration for fixing the decorative molding 5 to the exterior side surface of the door body 1 using the fixing parts 7 will be further described below.

[0016] (Fixed with fixing parts for molding material) As shown in Figures 2(b), 3(a), and 4, the molding material 51 of this embodiment has a pair of locking portions 51d, 51d extending along the longitudinal direction formed at the left-right central position of the door-side surface of the decorative wall 51a. Each of the pair of locking portions 51d, 51d has a locking claw portion 51e, 51e whose tips extend close to each other, and the surface of the locking claw portion 51e facing the door body 1 is an inclined surface that slopes toward the outside of the room as it approaches the center of the left and right sides of the molding material 51.

[0017] On the other hand, as shown in Figures 2, 3(b), and 4, the door body 1 of this embodiment has fixing parts 7 attached to upper and lower portions on the exterior side surface so as to correspond to the mounting positions of the decorative molding 5. The fixing part 7 is made of a resin material and, as shown in Figures 3(d), (e), and (f), has a circular base portion 7a and a number of locking pieces 7b, 7b arranged in a circular shape on the outer circumferential surface of the base portion 7a and protruding to the outside of the room.

[0018] Each of the multiple locking pieces 7b, 7b has a locking claw 7c, 7c at its protruding end that extends in the outer circumferential direction of the base portion 7a, and the tip surface of the locking claw 7c, 7c is an inclined surface that approaches the base portion 7a as it moves from the inside to the outside. The fixing part 7 has a mounting hole 7d formed in the center of the base portion 7a, and is fixed to the exterior-side plate material 1b of the door body 1 with a rivet 72.

[0019] (Installation procedure of the decorative molding according to the embodiment) When attaching the decorative molding 5 of this embodiment to the door body 1, the molding material 51 with the end caps 6, 6 attached to the upper and lower ends is brought close to the exterior side surface of the door body 1 with the mounting height adjusted. At that time, as shown in Fig. 3(c), the fixing part 7 attached to the door body 1 is brought close so as to be sandwiched and engaged by a pair of locking parts 51d, 51d provided on the interior side surface of the molding material 51.

[0020] The fixed part 7 sandwiched between a pair of locking portions 51d, 51d of the molding material 51 has the inclined surfaces of the locking claw portions 51e, 51e abut against the inclined surfaces of the locking claws 7c, 7c of the fixed part 7, causing the locking pieces 7b, 7b of the fixed part 7 to deform inward due to their elasticity, and to get past the pair of locking claw portions 51e, 51e of the molding material 51 without damaging them and be fitted between the locking portions 51d, 51d.

[0021] At the upper and lower portions, the decorative molding 5 is engaged by fitting the fixing part 7 between a pair of engaging portions 51d, 51d, and the double-sided tapes 511, 511 arranged on the indoor side of the left and right mounting walls 51c, 51c abut against and adhere to the outdoor side surface of the door body 1, and the decorative molding 5 is attached to the outdoor side surface of the door body 1.

[0022] In addition, the cross-sectional shape of the molding material 51 may be set so that when the locking pieces 7b, 7b of the fixing part 7 are fitted over the pair of locking claw portions 51e, 51e of the molding material 51, the pair of locking claw portions 51e, 51e are forced toward the outside of the room, so that when the decorative molding 5 is locked to the door body 1, the left and right mounting walls 51c, 51c are pressed against the door body 1.

[0023] (Effects of the opening device of the embodiment) In the front door of this embodiment, a fixing part 7 is attached to the door body 1, and the decorative molding 5 can be attached in accordance with the fixing part 7, so that it is easy to position the decorative molding 5 that enhances the design of the front door, and the front door can be easily manufactured.

[0024] In the front door of this embodiment, the fixing part 7 to be attached to the door body 1 is formed in a circular shape, and the locking pieces 7b are arranged in a circle along the outer periphery of the circle to form the fixing parts 7. Therefore, there is no need to be aware of the direction in which the fixing parts 7 are attached, and the fixing parts 7 can be easily attached. Furthermore, with the entrance door of this embodiment, the decorative molding 5 can be easily attached even when the decorative molding 5 is arranged diagonally or horizontally to the door body 1, making it possible to simplify the manufacture of the entrance door.

[0025] In the front door of this embodiment, the locking pieces 7b of the fixed part 7 are arranged in a row along the outer periphery of the circular base portion 7a. Therefore, when the locking portion 51d of the molding material 51 locks, only the locking pieces 7b that abut the locking portion 51d can be elastically deformed. This makes it possible to prevent damage to the locking portion 51d of the molding material 51 and the locking pieces 7b of the fixed part 7, and prevents defects from occurring during manufacturing.

[0026] The front door of this embodiment is configured so that when the molding material 51 of the decorative molding 5 is engaged with the fixing part 7, the left and right mounting walls 51c, 51c of the molding material 51 are pressed against the door body 1, thereby preventing peeling of the adhesive portion attaching the molding material 51 to the door body 1 and improving durability.

[0027] In the front door of this embodiment, the fixing part 7 is fixed by rivets 72 to the plate material 1b made of steel or the like on the exterior side of the door body 1. This means that no large holes are formed in the plate material 1b of the door body 1 and, in the event of a fire, the hole can be blocked by the fixing part 7 and rivets 72, preventing flames and smoke from penetrating through the hole and improving fire resistance.

[0028] It goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples. [Explanation of symbols]
