Description

[Technical field]

[0001] The present invention relates to a renovation cover member used when renovating building fixtures. [Background technology]

[0002] When renovating a fixture, there is a method of leaving the existing frame body in the building. For example, a new upper frame (hereinafter referred to as a new upper frame) is attached to the inner periphery of an existing upper frame (hereinafter referred to as an existing upper frame). In such fixtures, a cover member called an inner frame is provided so that the existing upper frame cannot be seen from the inside of the room. The cover member is formed from a metal such as an aluminum alloy, and is configured with a prospective extension part that extends from the new upper frame toward the room in the prospective direction, and a sight extension part that extends from the prospective extension part toward the outer periphery in the sight direction. The sight extension part is configured with two sight plate parts. A sight plate part for screwing is provided between the two sight plate parts. Of these, the frame is attached by abutting the two sight plate parts as support parts against the building, and from this state, screwing a screw member into the building through the sight plate part (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-125622 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, when the dimension of the existing upper frame along the sight direction is large, a cover member having a sight extension part of a corresponding dimension can be applied. However, in the above-mentioned cover member, the extension length of the two sight plate parts extending almost parallel to each other is large, making it difficult to mold it as an extruded shape material. In addition, this type of cover member has a plurality of grooves called break lines on the sight extension part and the two sight plate parts, and can be cut at appropriate locations to accommodate various dimensions of fittings. However, it is difficult to insert a tool between the two sight plate parts, and even if there is a break line, there is a concern that the work of cutting will become complicated.

[0005] In view of the above-mentioned circumstances, an object of the present invention is to provide a repair cover member that can be easily molded and that can facilitate the work of cutting the sight plate portion. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the renovation cover member of the present invention has a main cover plate portion that is provided on the indoor side of a new frame body provided on the inner periphery of an existing frame body, and extends in a prospective direction from the new frame body toward the indoor room, and then has an extending edge portion bent toward the outer periphery, a first support plate portion that extends in a prospective direction from an edge portion located on the outer periphery of the main cover plate portion toward the outer periphery, a screw plate portion that extends in a prospective direction from the main cover plate portion toward the indoor room, and a second support plate portion that extends in a prospective direction from an edge portion located on the indoor side of the screw plate portion toward the outer periphery, and is a renovation cover member in which a screw member for fixing is screwed into a main body via the screw plate portion while being supported via the first support plate portion and the second support plate portion, and is characterized in that the first support plate portion and the second support plate portion are molded separately from each other. Effect of the Invention

[0007] According to the present invention, since the first support plate portion and the second support plate portion are molded separately from each other, they can be easily molded as extruded members even when their extension dimensions are large. Moreover, since the first support plate portion and the second support plate portion can be handled separately, the operation of cutting them to any desired dimensions can be easily performed.

In the case of an object that extends along the vertical direction, such as a vertical frame, the direction along the horizontal direction perpendicular to the prospect direction is called the "finding direction." A surface along the prospect direction may be called a "finding surface."

[0010] 1 to 3 show fittings to which a cover member for renovation according to an embodiment of the present invention is applied. The fittings exemplified here are doors used at the entrance of buildings such as detached houses, and in particular, a fitting door for renovation that is installed while leaving the existing frame body 1 is exemplified. That is, in this fitting, a new upper frame 11, lower frame 12, and left and right vertical frames 13 are installed on the inner periphery of the existing upper frame 1a, lower frame 1b, and left and right vertical frames 1c that are attached to the framework B, thereby forming a frame body 10 for supporting the door panel P so that it can be opened and closed. The new upper frame 11, lower frame 12, and left and right vertical frames 13 are extruded members formed from metals such as aluminum alloys, and are configured so that the portions along the entire length along the longitudinal direction have a substantially uniform cross-sectional shape. For convenience, in the following, the components of the existing frame body 1 that remain on the structure B will be referred to as "existing" (existing upper frame 1a, etc.), and the components of the newly installed frame body 10 will be referred to as "new upper frame 11, etc.) to distinguish between the two.

[0011] The new upper frame 11 and the new vertical frame 13 are each connected by a resin bridge material 23 between the metal molding part on the outside of the room (hereinafter referred to as the outer metal molding part 21) and the metal molding part on the inside of the room (hereinafter referred to as the inner metal molding part 22). The outer metal molding part 21 and the inner metal molding part 22 each have a hollow shape with a roughly rectangular cross section. The inner metal molding part 22 is provided with a door stop piece 22a facing the inner circumference on the part that becomes the inner circumference. The new upper frame 11 and the new vertical frame 13 having the above configuration are attached to the parts that become the inner circumference of the existing upper frame 1a and the existing vertical frame 1c, respectively, via reinforcing metal fittings 24.

[0012] Outer frames 30A, 30B are provided between the visible surfaces of the new upper frame 11 and the new vertical frame 13 facing the outside and the outer surface Wa of the exterior wall material W, while inner frames 40A, 40B are provided between the visible surfaces of the new upper frame 11 and the new vertical frame 13 facing the inside of the room and the visible surface that is the inner periphery of the frame plate 25 on the structural body side provided on the inside of the room. The outer frames 30A, 30B and the inner frames 40A, 40B are each an extruded material formed from a metal such as an aluminum alloy.

[0013] The outer frame 30A of the new upper frame 11 is composed of an upper first cover plate portion 31 and an upper second cover plate portion 32. The upper first cover plate portion 31 is attached to the surface of the new upper frame 11 facing the outside, and extends toward the outer periphery, then extends toward the outside, and further extends toward the outer periphery. The upper second cover plate portion 32 extends from the edge of the upper first cover plate portion 31 on the outer periphery side toward the inside of the room. The upper first cover plate portion 31 and the upper second cover plate portion 32 are molded separately from each other and then connected to each other to form the outer frame 30A. The upper first cover plate portion 31 extends to the outer periphery beyond the existing upper frame 1a, and the extended edge portion reaches a position facing the outer surface Wa of the exterior wall material W. The upper second cover plate portion 32 has a plurality of fold lines 32a arranged in parallel along the left-right direction in the projection direction. The extended edge portion of the upper second cover plate portion 32 is cut at a position close to the outer surface Wa of the exterior wall material W, and then sealing material S is filled between the exterior wall material W and the extended edge portion so that it contacts the exterior wall material W without any gaps.

[0014] The outer frame 30B of the new vertical frame 13 is composed of a first side cover plate portion 33 and a second side cover plate portion 34. The first side cover plate portion 33 is attached to the surface of the new vertical frame 13 facing the outside of the room, and extends toward the outside of the room and then toward the outer periphery. The second side cover plate portion 34 extends from the edge of the first side cover plate portion 33 on the outer periphery side toward the room. The first side cover plate portion 33 and the second side cover plate portion 34 are molded separately from each other and then connected to each other to form the outer frame 30B. The first side cover plate portion 33 extends to the outer periphery beyond the existing vertical frame 1c, and the extended edge portion reaches a position facing the outer surface Wa of the exterior wall material W. The second side cover plate portion 34 has a plurality of fold lines 34a arranged in parallel along the left-right direction in the projection direction. The extended edge portion of the lateral second cover plate portion 34 is cut at a position close to the outer surface Wa of the exterior wall material W, and then sealing material S is filled between the exterior wall material W and the extended edge portion so that it contacts the exterior wall material W without any gaps.

[0015] As shown in Fig. 4, the inner frame 40A of the new upper frame 11 and the inner frame 40B of the new vertical frame 13 are each configured with a cover molding 41 and a support part molding 42. The cover molding 41 is formed by integrally molding a main cover plate portion 41a and a first support plate portion 41b, and is generally L-shaped in appearance. The support part molding 42 is formed by integrally molding a second support plate portion 42a, a screw plate portion 42b, and a connecting piece 42c.

[0016] The main cover plate portion 41a of the cover molded body 41 extends in the front direction, and then the inner circumferential edge portion is bent toward the outer circumferential side to form a flat plate shape. In the main cover plate portion 41a extending in the front direction, a plurality of fold lines 41c along the left-right direction are arranged in parallel in the front direction. The first support plate portion 41b forms a flat plate shape extending in the front direction from the edge portion located on the outer circumferential side of the main cover plate portion 41a toward the outer circumferential side. In the first support plate portion 41b, a plurality of fold lines 41d along the left-right direction are arranged in parallel in the front direction. In this cover molded body 41, an engagement portion 41e is provided on the front surfaces of the main cover plate portion 41a and the first support plate portion 41b facing the interior of the room. The engagement portion 41e has engagement fin portions 41f protruding in the directions facing each other from the inner circumferential edge portion and the outer circumferential edge portion.

[0017] The second support plate 42a of the support molded body 42 is flat and extends in the find direction. The second support plate 42a has a plurality of fold lines 42d arranged in the left-right direction in the find direction. The screw plate 42b extends in the find direction from a portion located on the inner periphery of the find surface of the second support plate 42a facing the outside of the room toward the outside of the room. The extension dimension of the screw plate 42b is set to be slightly larger than the head outer dimension of the screw member 45 to be screwed. The connecting piece 42c is flat and extends in the find direction from the extending edge of the screw plate 42b, and can be engaged between the engaging fins 41f of the engaging portion 41e provided on the cover molded body 41. The edge located on the inner periphery of the connecting piece 42c and the edge located on the inner periphery of the second support plate 42a are each provided with a cap attachment piece 42e. The cap mounting pieces 42e are for mounting the cap member 43 therebetween.

[0018] The inner frames 40A, 40B configured as described above are connected to each other in a state in which the first support plate portion 41b and the second support plate portion 42a extend substantially parallel to each other by engaging the connecting piece 42c with the engaging portion 41e, and from this state, the screw member 45 is screwed into the frame B via the screw plate portion 42b and the frame plate 25 on the frame side, so that the inner frames 40A, 40B are attached to the frame B in a state in which the space between the front surface of the new upper frame 11 facing the room and the frame plate 25 on the frame side, and the space between the front surface of the new vertical frame 13 facing the room and the frame plate 25 on the frame side, are covered. The extended edge of the main cover plate portion 41a is cut at a position close to the front surface of the new upper frame 11 facing the room or the front surface of the new vertical frame 13 facing the room, so that the gap between the front surface and the front surface is minimized. The extended edge of the first support plate portion 41b and the extended edge of the second support plate portion 42a are cut at a position close to the expected surface on the inner periphery of the frame plate 25 on the main frame side, so that they come into contact with the frame plate 25 on the main frame side when the screw member 45 is screwed in, and are stably attached to the main frame B. The gap between the second support plate portion 42a located on the indoor side and the frame plate 25 on the main frame side is filled with a sealant S.

[0019] Here, in the above-mentioned inner frames 40A, 40B, the first support plate portion 41b and the second support plate portion 42a, which extend substantially parallel to each other, are molded separately from each other. Therefore, even if the extension dimensions of the first support plate portion 41b and the second support plate portion 42a are large, they can be easily molded as extrusion molded bodies. Moreover, when cutting the first support plate portion 41b and the second support plate portion 42a, it is possible to perform this before the cover molded body 41 and the support portion molded body 42 are connected, and this work can be easily performed. After the screw members 45 are screwed, the cap members 43 are attached to the cap attachment pieces 42d, respectively, so that the screw members 45 cannot be seen from the outside, and the appearance quality can be improved.

[0020] In the above-described embodiment, the inner frames 40A, 40B are formed by a cover molding 41 in which the main cover plate portion 41a and the first support plate portion 41b are integrally molded, and a support portion molding 42 in which the second support plate portion 42a, the screw plate portion 42b and the connecting piece 42c are integrally molded. However, this is not limited to this as long as the first support plate portion 41b and the second support plate portion 42a are separate from each other.

[0021] 5 shows inner frames 140A and 140B which are modified examples. The inner frames 140A and 140B of the modified examples are provided on the inner periphery of the new upper frame 11 and the inner periphery of the new vertical frame 13, as in the embodiment, and have a cover body 141 and a support part molding 142. The cover body 141 is formed by integrally molding a main cover plate part 141a, a screw plate part 141b, and a second support plate part 141c, and has an approximately L-shape in appearance. The support part molding 142 is formed by integrally molding a first support plate part 142a and a connecting piece 142b.

[0022] The main cover plate 141a of the cover body 141 extends in the front direction, and then the edge on the interior side is bent toward the outer periphery to form a flat plate shape. In the part of the main cover plate 141a extending in the front direction, a plurality of folding lines 141d along the left-right direction are arranged side by side in the front direction. The screw plate 141b is a flat plate extending in the front direction from the edge located on the outer periphery side of the main cover plate 141a toward the interior. The second support plate 141c extends in the front direction from the edge located on the interior side of the screw plate 141b toward the outer periphery side. The second support plate 141c has a plurality of folding lines 141e along the left-right direction arranged side by side in the front direction. In this cover body 141, an engagement portion 141f is provided on the main cover plate 141a. The engaging portion 141f is configured to have an engaging groove portion 141g provided on an edge portion located on the outer periphery side of the main cover plate portion 141a, and an engaging protrusion 141h provided on a portion of the edge portion on the inner periphery side of the second support plate portion 141c facing the outside of the room. In addition, a cap attachment piece 141j for attaching a cap member is provided on the edge portion located on the inner periphery side of the main cover plate portion 141a and the second support plate portion 141c.

[0023] The first support plate 142a of the support molded body 142 is flat and extends along the front direction. The first support plate 142a has a plurality of fold lines 142c aligned along the left-right direction in the front direction. The connecting piece 142b is provided on the edge located on the inner periphery of the first support plate 142a. In this modification, the connecting piece 142b is configured with a hook piece 142d and an insertion piece 142e. The hook piece 142d is bent from the first support plate 142a toward the outside of the room, then extends toward the inner periphery, and is further inclined so as to gradually become closer to the inside of the room toward the inner periphery. The hook piece 142d is formed so that the extended edge is inserted between the main cover plate 141a and the engagement protrusion 141h when the bent portion on the outer periphery side is abutted against the projection surface located on the outer periphery side of the screw plate 141b. The insertion piece 142e extends from the portion of the hook piece 142d facing the room toward the room in the front direction. The insertion piece 142e is inserted into the engagement groove 141g when the extended edge of the hook piece 142d is inserted between the main cover plate 141a and the engagement protrusion 141h.

[0024] As in the embodiment, the inner frames 140A, 140B of this modified example are connected to each other in a state in which the first support plate portion 142a and the second support plate portion 141c extend approximately parallel to each other by engaging the connecting piece 142b with the engaging portion 141f, and from this state, the screw member 45 is screwed into the body B via the screw plate portion 141b and the body side frame plate 25, so that the inner frames 140A, 140B are attached to the body B in a state in which the space between the visible surface facing the room of the newly installed upper frame 11 and the body side frame plate 25 and the space between the visible surface facing the room of the newly installed vertical frame 13 and the body side frame plate 25 are covered.

[0025] Moreover, in the inner frames 140A and 140B, the first support plate portion 142a and the second support plate portion 141c, which extend substantially parallel to each other, are formed separately from each other. Therefore, even if the extension dimensions of the first support plate portion 142a and the second support plate portion 141c are large, they can be easily molded as extrusion molded bodies. Moreover, when cutting the first support plate portion 142a and the second support plate portion 141c, this can be done before the cover body 141 and the support portion molded body 142 are connected, and this work can be easily performed.

[0026] In the above-described embodiment, a renovation cover member applied to a front door is illustrated as an example, but it can also be applied to other renovation fittings.
