Description

[Technical Field]

[0001] The present invention relates to a door panel and a fixture having a door panel. [Background technology]

[0002] In some fittings in which a door panel is supported on a frame so that it can be opened and closed, attachments made of metal such as aluminum are attached to the four outer periphery of the wooden core. The attachments are attached to the core by screwing in threaded members from the outer periphery (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 58-68590 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-described door panel, when a screw member is simply screwed into the door panel, the head of the screw member protrudes from the outer surface of the attachment, which is not necessarily desirable in terms of appearance quality. This problem can be solved by applying a countersinking process to the attachment. That is, by applying a countersinking process to the attachment, the head of the screw member can be accommodated in the countersinking portion. However, in a countersinking attachment, the inner surface facing the core member protrudes in a truncated cone shape. Therefore, even when the screw member is screwed into the door panel, only the countersinking portion partially abuts against the core member, which raises concerns about the attachment being unstable.

[0005] In view of the above circumstances, the present invention aims to provide a door panel and fittings that can stabilize the attachment state of an attachment and prevent the appearance quality from being impaired. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the door panel and fittings of the present invention are door panels having a door base formed on all four sides from wood or wood-based material, and a metal attachment that covers at least the outer peripheral surface of the door base is attached to the outer peripheral side of the door base, and the attachment is provided with a countersunk processing for a fixing screw so that it protrudes onto the inner surface facing the outer peripheral surface of the door base, and protrusions are provided on both sides of the countersunk processing on the inner surface. [Effects of the Invention]

[0007] According to the present invention, the protrusions provided on both sides of the countersinking process abut the door base, thereby stabilizing the installation state and preventing the appearance quality from being impaired. [Brief explanation of the drawings]

[0009] Preferred embodiments of the door panel and fittings according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "invisible direction" and "visible direction" will be used below. The "invisible direction" is the direction along the depth of the fittings, as indicated by arrow A in the drawings. A surface along the invisible direction will be referred to as a "visible face." The "visible direction" is the direction perpendicular to the invisible direction in the case of an object that extends horizontally, such as a top frame. In the case of an object that extends vertically, such as a vertical frame, the "visible direction" is the direction perpendicular to the invisible direction. A surface along the invisible direction will be referred to as a "visible face."

[0010] 1 to 3 show a fitting according to an embodiment of the present invention. The fitting illustrated here is an entrance door comprising a frame 10 and a door panel 20 supported by the frame 10 so as to be openable and closable. The frame 10 comprises left and right vertical frames 11 and an upper frame 12 extending between the upper ends of the vertical frames 11, and is attached to an opening that serves as the entrance to a building. The vertical frames 11 and the upper frame 12 each have base frame portions 11a and 12a extending along the front-facing direction, and doorstop plates 11b and 12b extending inward from portions of the front-facing surfaces of the base frame portions 11a and 12a that are closer to the exterior of the room. A seal member 13 is attached to the extending edges of the doorstop plates 11b and 12b via seal attachment portions 11c and 12c, respectively, on the portions facing the interior of the room.

[0011] The door panel 20 comprises a door base 21 and attachments 22 attached to the four periphery of the door base 21. The door base 21 comprises a panel frame 30 formed by assembling frame members 31 made of wood or wood-based material around the four periphery, and surface members 32 attached to both the front and back sides of the panel frame 30, and is configured to have a rectangular outer shape. The interior of the panel frame 30 is filled with a filler material 33. The dimensions of the door base 21 along its left and right sides are set so that it can simultaneously abut against the seal members 13 attached to the vertical frame 11 while maintaining a gap between it and the base frame portion 11a of the vertical frame 11. The dimensions of the door base 21 along its top and bottom are set so that a gap is created between it and the floor F when it abuts against the seal members 13 attached to the upper frame 12.

[0012] The attachments 22 are extruded shapes made of metal such as aluminum alloy, and are configured to have a substantially uniform cross-sectional shape along their entire length. In this embodiment, the attachments 22 attached to the top edge and both side edges of the door base 21 have the same cross-sectional shape.

[0013] That is, the attachments 22 attached to the upper and both side edges of the door base 21 each include a base plate 22a and two side plate portions 22b, 22c. The base plate portion 22a is flat. The base plate portion 22a of the attachment attached to the upper edge of the door base 21 (hereinafter referred to as the upper attachment 22A when distinguished) has a length that extends substantially along the entire length of the upper edge, while the base plate portion 22a of the attachment attached to the side edge of the door base 21 (hereinafter referred to as the side attachment 22B when distinguished) has a length that extends substantially along the entire length of the side edge. Each base plate portion 22a has screw insertion holes 22d formed at multiple positions along the length in a portion that is approximately the center in the width direction, and two protrusions 22e formed on one surface (hereinafter referred to as the inner surface) on both sides of the screw insertion holes 22d. The screw insertion hole 22d allows the shank 40a of a flat head screw (fixing screw) 40 to be inserted therethrough. A countersunk processing 22f is applied to the screw insertion hole 22d. The countersunk processing 22f is configured to have a recess 22g on the other surface (hereinafter referred to as the outer surface) of the base portion 22a, into which the head 40b of the flat head screw 40 can be inserted, and a truncated conical protrusion 22h on the inner surface of the base portion 22a. The protrusion 22e is a protrusion that continues along the longitudinal direction of the attachment 22. The protrusion dimensions of the protrusions 22e are the same and are set larger than the protrusion 22h of the countersunk processing 22f. The two side plate portions 22b and 22c each extend from the edge of the base portion 22a in a direction approximately perpendicular to the base portion 22a. One side plate portion 22b protrudes only toward the inner surface from the base portion 22a. The other side plate portion 22c protrudes from the base portion 22a toward both surfaces. The protrusions of the side plate portions 22b and 22c from the inner surface are equal and greater than the protrusions from the outer surface. The distance between the side plate portions 22b and 22c is set to a dimension that allows the edge of the door base 21 to be inserted.

[0014] The attachment attached to the lower edge of the door base 21 (hereinafter referred to as the lower attachment 22C when distinguished from the lower attachment 22C) has a flat base plate 22a and two side plate portions 22b, 22c provided on both side edges of the base plate 22a. The base plate 22a extends along almost the entire length of the lower edge. The base plate 22a has screw insertion holes 22d formed at multiple positions along its length in a portion that is approximately the center of the width direction, and a single protrusion 22e formed on its inner surface between the screw insertion hole 22d and one of the side plate portions 22b. The screw insertion hole 22d allows the shank 40a of a flat head screw 40 to be inserted therethrough. Similar to the upper attachment 22A, the screw insertion holes 22d of the lower attachment 22C are each formed with a countersunk groove 22f. The protrusion 22e is a continuous protrusion along the length of the attachment 22 and is positioned closer to the screw insertion hole 22d than the side plate 22b. The protrusion dimension of the protrusion 22e is set larger than the protrusion 22h of the countersink 22f. The base plate 22a also has an attachment portion 22i adjacent to the other side plate 22c. The attachment portion 22i opens to the outer surface of the base plate 22a and protrudes from the inner surface of the base plate 22a. A mohair (protrusion member) 50 is attached to the attachment portion 22i so as to protrude from the outer surface. The protrusion dimension of the attachment portion 22i from the inner surface is approximately the same as that of the protrusion 22e. The two side plate portions 22b and 22c each protrude only from the edge of the base plate 22a toward the inner surface and extend in a direction approximately perpendicular to the base plate 22a. The side plate portions 22b and 22c have the same protrusion size from the inner surface, and the distance between the side plate portions 22b and 22c is set to a size that allows the edge of the door base 21 to be inserted therethrough.

[0015] The attachment 22 configured as described above is attached to the four periphery of the base plate 22a by inserting the edge of the door base 21 between the two side plates 22b, 22c after applying sealant S to the outer peripheral surface of the door base 21 or the inner surface of the base plate 22a, and then threading flat head screws 40 into the frame material 31 through the screw insertion holes 22d in the base plate 22a. As is clear from Figures 2 and 3, the upper attachment 22A and the side attachment 22B are attached with the side plates 22c protruding from the outer surface facing the interior. The lower attachment 22C is attached with the mohair 50 facing the exterior.

[0016] As described above, the base plate portion 22a of the upper attachment 22A and the base plate portion 22a of the side attachment 22B are each provided with two protrusions 22e on their inner surfaces. Therefore, when the countersunk head screw 40 is screwed in, these two protrusions 22e come into contact with the outer peripheral surface of the door base 21, and the protrusions 22h of the countersunk portion 22f do not come into contact with the door base 21. As a result, the upper attachment 22A and the side attachment 22B are stably attached to the door base 21 with a gap d secured between them. On the other hand, the lower attachment 22C has the protrusions 22e and the mounting portion 22i protruding from the inner surface of the base plate 22a. Therefore, with regard to the lower attachment 22C, the protrusion 22h of the countersunk processing 22f does not come into contact with the door base 21, a gap d is maintained between the lower attachment 22C and the door base 21, and the lower attachment 22C is attached to the door base 21 in a stable state.

[0017] Furthermore, even if the flat head screw 40 is screwed in excessively, the gap d ensures that the desired thickness of the sealing material S is maintained. As a result, even if water such as rainwater seeps in through the joint between the attachment 22 and the door base 21, there is no risk of the seeping water reaching the frame material 31 made of wood or a wood-based material, and problems such as corrosion of the frame material 31 due to water wetting can be prevented.

[0018] As shown in FIG. 5 , in this embodiment, the side attachments 22B are attached to the lower attachment 22C so that the side plate portions 22b and 22c of the side attachment 22B abut against the upper surfaces of the side plate portions 22b and 22c of the lower attachment 22C. Furthermore, a resin cap 51 is attached to the small end of the lower attachment 22C. The cap 51 is integrally molded with a cap body 51a that covers the small end of the lower attachment 22C and a portion of the side attachment 22B, and an insert piece 51b that protrudes from the inner surface of the cap body 51a at a position that becomes the lower edge. The cap 51 is attached to the door base 21 with the insert piece 51b inserted into a gap d provided between the base portion 22a of the lower attachment 22C and the door base 21.

[0019] The door panel 20 described above has one side edge supported by a vertical frame 11 via a hinge 1, and can be opened and closed so as to protrude toward the interior of the room. A locking member 2 is provided between the door panel 20 and the vertical frame 11 at the door edge. When the locking member 2 is in the locked state, the door panel 20 is maintained in the closed position, and the opening in the frame 10 is closed. When the door panel 20 is placed in the closed position, the seal member 13 is simultaneously abutted on three sides. Therefore, there is no risk of outside water or air entering the room through the top and side edges of the door panel 20, or of outdoor light reaching the room.

[0020] Meanwhile, a gap is maintained between the door panel 20 and the floor F. Therefore, even if water accumulates on the floor F, it is possible to prevent the water from the floor F from seeping into the door base 21 through the lower edge of the door panel 20. Moreover, the lower attachment 22C is provided with mohair 50 on the portion facing the exterior. This makes it possible to prevent insects and light from outside from entering the interior of the room.

[0021] In the entrance door constructed as described above, the frame material 31 of the door base 21 is made of wood or wood-based material. When heated by sunlight, the indoor portion of the frame material 31 dries, raising concerns that it may deform and become convex toward the interior. However, in the entrance door described above, side attachments 22B are attached to both side edges of the door base 21. When heated by sunlight, these side attachments 22B thermally expand and deform, becoming convex toward the exterior. Therefore, the deformation of the door base 21 and the deformation of the side attachments 22B cancel each other out, making it possible to suppress deformation of the door panel 20.

[0022] In the above-described embodiment, a fixture having one door panel 20 attached to the frame 10 is exemplified. However, as shown in the modified example in FIGS. 6 and 7, two door panels may be attached to the frame. That is, in this modified fixture, one side attachment (hereinafter referred to as the front attachment 22D when distinguishing between them) attached to the side edge of the door base 21 constituting the door panel 120 is formed by integrally molding a base plate 22a, two side plates 22b and 22c, and a cover plate 22j. The base plate 22a is the same as that in the embodiment. The side plates 22b and 22c, like the lower attachment 22C, are configured to extend only toward the inner surface of the base plate 22a. The cover plate 22j extends from one edge of the base plate 22a along the projection direction, then bends and extends toward the outer periphery. A seal mounting portion 22k is provided on the surface of the cover plate portion 22j that extends toward the outer periphery and faces the base plate portion 22a. This front attachment 22D is attached to the door base 21 of one door panel 20 so that the cover plate portion 22j is located on the indoor side, and is attached to the door base 21 of the other door panel 20 so that the cover plate portion 22j is located on the outdoor side. The upper attachment 22A and the lower attachment 22C are the same as those in the embodiment. Furthermore, the same reference numerals are used in the modified example to designate the same components as those in the embodiment.

[0023] In this modified example, the door panels 120 are arranged so that the front attachments 22D face each other, and hinges 1 are interposed between the side attachments 22B and the vertical frame 11, allowing each to open and close relative to the frame body 10 and protrude toward the interior. A seal member 121 is attached to the seal mounting portion 22k of the cover plate 22j located on the exterior side of the room. A locking member 2 is provided between the front attachments 22D to maintain the two door panels 120 in the closed position. When the two door panels 120 are positioned in the closed position, the seal member 121 abuts against the other door panel 120, and the cover plate 22j is positioned to hide the gap between them. This prevents water or air from entering the room from between the door panels 120, and prevents outdoor light from reaching the room.

[0024] Furthermore, in this modified fitting, the projections 22e and the mounting portions 22i are provided on the inner surface of the base portion 22a of each of the attachments 22A, 22B, 22C, and 22D, so that the projections 22h of the countersinking 22f do not come into contact with the door base 21. As a result, the attachments 22A, 22B, 22C, and 22D are attached to the door base 21 in a stable state, with a gap d secured between them.

[0025] In the above-described embodiment, a door panel is illustrated in which the frame material of the door base is made of wood or a wood-based material. However, the present invention is not limited to this. For example, the entire panel base may be made of wood or a wood-based material, as long as wood or a wood-based material is visible around the four periphery of the panel base. Furthermore, the attachments do not necessarily have to be provided around the entire four periphery of the panel base; they may be provided only on both side edges or only on the bottom edge. Furthermore, as long as the attachments are made of metal, they do not necessarily have to be made of an aluminum alloy. Furthermore, while mohair is used as the protruding members, sealing members provided in various locations may also be used as protruding members.

[0026] As described above, the door panel of the present invention is a door panel having a door base configured so that wood or wood-based material is visible on at least four outer peripheries, and is characterized in that a metal attachment that covers at least the outer peripheral surface of the door base is attached to the outer peripheral side of the door base, and the attachment is provided with a countersunk groove for a fixing screw so that it protrudes onto the inner surface facing the outer peripheral surface of the door base, and protrusions are provided on both sides of the countersunk groove on the inner surface. According to this invention, the protrusions provided on both sides of the countersinking process come into contact with the door base, thereby stabilizing the installation state and preventing the appearance quality from being impaired.

[0027] Furthermore, the present invention is characterized in that, in the door panel described above, the attachments are attached so as to cover the outer peripheral surfaces of the door bases arranged on the left and right sides. According to this invention, the attachments arranged on the left and right sides can prevent the door panel from being deformed so as to be curved.

[0028] Furthermore, the present invention is characterized in that, in the door panel described above, the attachment is attached so as to cover the outer peripheral surface of the door base portion disposed below. According to this invention, the attachment disposed below can prevent the door base from getting wet even when water such as rainwater has accumulated on the floor.

[0029] Furthermore, the present invention is characterized in that in the door panel described above, the attachment is provided with a protruding member that protrudes toward the outer periphery. According to this invention, the gap between the outer surface of the attachment placed below and the floor or lower frame can be increased to more reliably prevent water from getting in, while also preventing insects and light from entering from outside. Mohair or a sealing material can be used as the protruding member.

[0030] The present invention is also characterized in that, in the above-mentioned door panel, the protrusion member is attached to a mounting portion provided on the attachment, the mounting portion opens on the outer surface of the attachment and protrudes from the inner surface, the protrusion member is attached to the opening on the outer surface, and the portion protruding from the inner surface also serves as the protrusion portion. According to this invention, the mounting portion also serves as the protrusion, so the structure of the attachment does not become complicated.

[0031] The present invention is also characterized in that, in the above-mentioned door panel, a gap is formed between the door base and the attachment by the protrusion, and a sealant is provided in the gap. According to this invention, the projection accurately defines the size of the gap between the door base and the attachment, ensuring a desired thickness for the sealant.

[0032] The present invention is also characterized in that, in the above-mentioned door panel, a gap is formed between the door base and the attachment by the protrusion, and an insert piece of a cap attached to the end of the attachment is inserted into the gap. According to this invention, the attachment strength of the cap can be ensured by inserting the insertion piece into the gap.

[0033] Furthermore, the fitting according to the present invention is characterized in that the door panel described above is supported by a frame so as to be openable and closable. According to this invention, the protrusions provided on both sides of the countersinking process come into contact with the door base, thereby stabilizing the installation state and preventing the appearance quality from being impaired.
