Description

[Technical field]

[0001] The present invention relates to a frame structure formed by joining a plurality of frame members, such as a shoji screen, and to a fixture equipped with a frame structure. [Background technology]

[0002] In a shoji door, a fitting with a vertical frame extending up and down and a horizontal frame extending left and right, for example, the small end of the horizontal frame faces the projecting surface of the vertical frame and is joined together. A clamping fin is provided on one edge of the projecting surface on the inner periphery of each of the vertical frame and horizontal frame, and a ridge is attached to the other edge, and the peripheral edge of the surface material is clamped between the clamping fin and the ridge (for example, see Patent Document 1).

[0003] [Patent Document 1] JP 2010-150910 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the projection surface of the vertical frame is provided with a protruding edge engagement piece for attaching the edge. Therefore, if the horizontal frame and the vertical frame are joined with the edge engagement piece still attached, there is a concern that the joining state between them may become unstable, such as the vertical frame being tilted relative to the horizontal frame. In other words, the horizontal frame and the vertical frame are joined together with only the edge engagement piece abutting against the small end of the horizontal frame. For this reason, in the past, it was necessary to remove the edge engagement piece in advance from the part where the small end of the horizontal frame faces, which makes the manufacturing work of the shoji screen complicated. The above-mentioned problem can also occur when the horizontal frame and the vertical frame are joined with the small end of the vertical frame facing the projection surface of the horizontal frame.

[0005] In view of the above-mentioned circumstances, an object of the present invention is to provide a frame structure and fittings that can simplify manufacturing work. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides a frame structure comprising a first frame member and a second frame member joined together in a state in which the small end of the second frame member faces the inner peripheral surface of the first frame member, and the first frame member has a small end portion on the inner peripheral surface of the first frame member. Interior edge A ridge engagement piece for attaching a ridge is provided on the inner peripheral surface of the first frame member so as to protrude in the inner peripheral direction. Outside edge a protruding piece that can be abutted against one outer surface of the second frame member protrudes in the same direction as the pressing edge engagement piece, and is provided so that the protruding dimension is larger than that of the pressing edge engagement piece; A seal member is attached to the inner peripheral surface of the first frame member so that the seal member is attached to the seal member engagement piece so as to protrude inward, and the protruding piece protrudes inward to a position corresponding to the protruding edge of the seal member, and an attachment is provided on the inner surface of the protruding piece to clamp a surface material between the seal member and the seal member, The portion between the protruding piece and the edge engagement piece is characterized in that an abutment surface portion with which the small end portion of the second frame can abut is provided corresponding to the protruding height of the edge engagement piece.

[0007] Furthermore, the fittings of the present invention are characterized in that the first frame is arranged in the vertical direction, the above-mentioned frame structure is arranged so as to be openable and closable relative to the frame body with the protruding piece positioned on the outside of the room, and the visible surface of the edge attached to the first frame facing into the room and the visible surface of the second frame facing into the room are each arranged on the same plane as the visible surface of the first frame facing into the room. Effect of the Invention

[0008] According to the present invention, since the first frame has an abutment surface between the protruding piece and the edge engagement piece, the small end of the second frame abuts against the abutment surface and the edge engagement piece, and the outer surface of the second frame can be opposed to the inner peripheral surface of the first frame while abutting against the protruding piece. Therefore, the first frame and the second frame can be joined in a stable state without performing any cutting or other processing on the first frame in advance, which makes it possible to facilitate the manufacturing process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, a preferred embodiment of the frame structure and fittings according to the present invention will be described in detail with reference to the attached drawings. In the following, for convenience, the terms "visible direction" and "visible direction" are used. The "visible direction" is the direction along the depth of the fittings, as shown by the arrow A in the figure. The surface along the visible direction may be called the "visible surface." The "visible direction" is the direction along the top and bottom perpendicular to the visible direction in the case of an object that extends along the horizontal direction, such as an upper frame or a lower frame. 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 visible direction is called the "visible direction." The surface along the visible direction may be called the "visible surface." In the following description, the direction of each component is specified in the position in which the fittings are attached to the framework.

[0011] 1 to 4 show a fitting to which a frame structure according to an embodiment of the present invention is applied. The fitting shown here is equipped with a frame 10 and a door panel 20 which is a frame structure, and the door panel 20 is supported by the frame 10 with multiple hinges 1 interposed between the frame 10 and the door panel 20 so that the door panel 20 can rotate around a hinge axis extending vertically.

[0012] The frame body 10 is composed of upper and lower horizontal frames 11, 12 and left and right vertical frames 13, 14, which are framed on all four sides to form a vertically long rectangular shape. The horizontal frames 11, 12 and the vertical frames 13, 14 are extruded shapes formed from metal such as aluminum alloy, and each is configured to have a substantially uniform cross-sectional shape over the entire length along the longitudinal direction. The upper horizontal frame (hereinafter referred to as the upper frame 11) is composed of a hollow upper frame base 11a and an abutting upper fin portion 11b protruding from the edge of the upper frame base 11a, which faces the room, toward the inner periphery. The lower horizontal frame (hereinafter referred to as the lower frame 12) is composed of a lower frame base 12a and an abutting lower fin portion 12b protruding from the edge of the lower frame base 12a, which faces the room, toward the inner periphery. The lower frame base 12a has a dimension along the front direction that is almost the same as that of the upper frame base 11a, and is generally hollow and opens to the bottom. Frame screw holes 15 are provided in the hollow parts of the horizontal frames 11, 12. The vertical frames 13, 14 have cross-sectional shapes that are almost symmetrical to each other on the left and right, and are composed of hollow vertical frame bases 13a, 14a and abutting vertical fins 13b, 14b that protrude from the edges on the inner periphery of the vertical frame bases 13a, 14a that face the room toward the inner periphery. The abutting upper fins 11b, the abutting lower fins 12b, and the abutting vertical fins 13b, 14b are provided with tension material attachment parts 16 on the visible surfaces facing the outside of the room at the protruding edges of each. The twill material attachment parts 16 are provided so as to protrude outside the room from the visible surfaces of the respective fin parts 11b, 12b, 13b, 14b. Although not shown in the drawing, these horizontal frames 11, 12 and vertical frames 13, 14 are connected to each other by abutting the small ends of the horizontal frames 11, 12 against the visible surfaces on the inner periphery of the vertical frames 13, 14, and then screwing frame mounting screws (not shown) into the frame screw holes 15 of the horizontal frames 11, 12 through the vertical frames 13, 14. The twill material attachment parts 16 mentioned above have twill material 17 attached so as to run continuously around the four periphery.

[0013] The door panel 20 is constructed by attaching upper and lower horizontal frames (second frames) 22, 23 and left and right vertical frames (first frames) 24, 25 to the four periphery of a face material 21 such as a glass plate having a vertically long rectangular shape. In this embodiment, three hinges 1 are provided between the vertical frame 14 located on the left side as viewed from the outside of the room and the vertical frame 25, and the door panel 20 is supported rotatably around these hinges 1 with respect to the frame body 10 so as to protrude to the outside of the room. A lock 2 is provided between the vertical frame 13 located on the right side as viewed from the outside of the room and the vertical frame 24, and a door handle 3 for releasing the lock 2 is provided on the vertical frame 24 located on the right side as viewed from the outside of the room. The horizontal frames 22, 23 and vertical frames 24, 25 that make up the door panel 20 are each an extruded member made of a metal such as an aluminum alloy, and each is configured to have a substantially uniform cross-sectional shape over its entire length in the longitudinal direction.

[0014] The horizontal frames 22, 23 have cross-sectional shapes that are almost symmetrical to each other at the top and bottom, and are configured with a horizontal frame base 22a, 23a that is hollow, and a clamping fin portion 22b, 23b that protrudes from the edge of the horizontal frame base 22a, 23a that is the outside of the room toward the inner circumference. As shown in Figure 5, the horizontal frame base 22a, 23a is substantially rectangular surrounded by two horizontal projection walls 41, 42 and two horizontal sight walls 43, 44, and has screw holes 45 at each of the four corners of the hollow portion. The horizontal frame base 22a, 23a has two horizontal push-edge engagement pieces 46, 47 provided on the horizontal projection wall 41 that is the inner circumference. The horizontal ridge engagement pieces 46, 47 are for attaching the horizontal ridge 50 to the interior edge of the horizontal frame bases 22a, 23a, and protrude inward from the interior edge of the surface 41a of the horizontal projection wall 41 and from a portion that is approximately the center of the horizontal projection wall 41. The horizontal ridge engagement piece provided on the interior edge (hereinafter referred to as the inner horizontal ridge engagement piece 46 when distinguishing between them) protrudes inward, and then the protruding edge is bent at approximately a right angle toward the outside of the room. The horizontal ridge engagement piece provided in the center (hereinafter referred to as the middle horizontal ridge engagement piece 47 when distinguishing between them) protrudes inward, and then the protruding edge is bent at approximately a right angle toward the room. As is clear from the figure, the protruding dimension of the middle horizontal edge engagement piece 47 and the inner horizontal edge engagement piece 46 is sufficiently smaller than the protruding dimension of the clamping fin portions 22b, 23b described below, and the protruding dimension of the middle horizontal edge engagement piece 47 is slightly smaller than the protruding dimension of the inner horizontal edge engagement piece 46. To show specifically for illustration, the protruding dimension of the middle horizontal edge engagement piece 47 is about twice the plate thickness of the horizontal frames 22, 23, and the protruding dimension of the inner horizontal edge engagement piece 46 is set to about three times the plate thickness of the horizontal frames 22, 23.

[0015] The horizontal shims 50 attached to the horizontal frames 22, 23 via these horizontal shim engagement pieces 46, 47 are extruded shapes made of metal such as aluminum alloy, and are configured to have a substantially uniform cross-sectional shape over the entire length along the longitudinal direction. In this embodiment, as shown in Fig. 2 and Fig. 5(c), the horizontal shims 50 are applied, which have a shim base plate portion 51, a panel support plate portion 52, and an engagement plate portion 53. The shim base plate portion 51 is disposed along the horizontal visible wall portion 43 on the indoor side of the horizontal frame base portions 22a, 23a. The panel support plate portion 52 is bent at a substantially right angle from the edge portion on the inner periphery of the shim base plate portion 51 toward the outside of the room, and then further bent toward the outer periphery. A dry inner seal member 5 is attached to the extended edge portion of the panel support plate portion 52. The engagement plate portion 53 extends at an angle from the edge on the outer periphery of the press base plate portion 51 toward the outside of the room so as to gradually become more and more outward. An engagement groove 54 is provided at the protruding corner portion between the press base plate portion 51 and the engagement plate portion 53, into which the bent portion of the inner horizontal press engagement piece 46 can engage. This horizontal press 50 is attached to the horizontal frame base portions 22a, 23a in a state where it protrudes inward from the indoor side of the horizontal frame base portions 22a, 23a by inserting the extended edge of the engagement plate portion 53 between the middle horizontal press engagement piece 47 and the horizontal projection wall portion 41 and engaging the bent portion of the inner horizontal press engagement piece 46 with the engagement groove 54.

[0016] The clamping fins 22b, 23b have approximately the same protruding dimension as the horizontal ridges 50 attached to the horizontal frame bases 22a, 23a, and have a seal mounting portion 48 on the facing surface of the protruding edge that faces the interior of the room. The seal mounting portion 48 is for mounting a dry outer seal member 6 on the portion that faces the interior of the room, and is provided so as to protrude into the room from the facing surface of the clamping fins 22b, 23b.

[0017] The vertical frames 24, 25 have cross-sectional shapes that are almost symmetrical on the left and right, and are configured with hollow vertical frame bases 24a, 25a and protruding pieces 24b, 25b that protrude from the edges of the vertical frame bases 24a, 25a on the outside of the room toward the inner periphery. The vertical frame bases 24a, 25a are surrounded by two vertical projection walls 61, 62 and two vertical observation walls 63, 64 to form an approximately rectangular shape. As is clear from Fig. 7, the vertical frame bases 24a, 25a are configured such that the dimension along the projection direction is larger than that of the horizontal frame bases 22a, 23a by approximately the plate thickness of the protruding pieces 24b, 25b, and when the facing surfaces 43a, 64a facing the room are positioned on the same plane, the facing surface 44a facing the outside of the horizontal frame bases 22a, 23a can be abutted against the facing surfaces of the protruding pieces 24b, 25b facing the room (hereinafter referred to as the inner surfaces 24c, 25c of the protruding pieces 24b, 25b). The vertical frame bases 24a, 25a have two vertical push-edge engagement pieces 65, 66 on the surface (inner peripheral surface) 61b of the vertical projection wall portion 61, which is the inner peripheral side. The two vertical spur engagement pieces 65, 66 are for attaching the vertical spur 70 to the interior edge of the vertical frame base 24a, 25a, and are composed of the interior vertical spur engagement piece 65 on the interior side and the middle vertical spur engagement piece 66 in the center, similar to the horizontal spur engagement pieces 46, 47 provided on the horizontal frames 22, 23. The protruding dimensions of the middle vertical spur engagement piece 66 and the inner vertical spur engagement piece 65 are sufficiently smaller than the protruding dimensions of the protruding pieces 24b, 25b described later, and the protruding dimension of the middle vertical spur engagement piece 66 is slightly smaller than the protruding dimension of the inner vertical spur engagement piece 65. To give a specific example, the protruding dimension of the middle vertical spur engagement piece 66 is about twice the plate thickness of the vertical frames 24, 25, and the protruding dimension of the inner vertical spur engagement piece 65 is set to about three times the plate thickness of the vertical frames 24, 25.

[0018] The vertical ridge 70, which is attached to the vertical frames 24, 25 via these vertical ridge engagement pieces 65, 66, is an extruded member formed from a metal such as an aluminum alloy, and is configured to have a substantially uniform cross-sectional shape over its entire length along the longitudinal direction. In this embodiment, as shown in Figures 3 and 6, the vertical ridge 70 has a ridge base plate portion 71, a panel support plate portion 72, and an engagement plate portion 73, similar to the horizontal ridge 50. An engagement groove 74 is provided at the protruding corner portion between the ridge base plate portion 71 and the engagement plate portion 73 in the vertical ridge 70, with which the bent portion of the inner vertical ridge engagement piece 65 can engage. A dry inner seal member 5 is attached to the extended edge portion of the panel support plate portion 72. This vertical flange 70 is attached to the vertical frame bases 24a, 25a in a state where it protrudes inward from the room side of the vertical frame bases 24a, 25a by inserting the tip of the engagement plate portion 73 between the middle vertical flange engagement piece 66 and the vertical projection wall portion 61 and engaging the bent portion of the inner vertical flange engagement piece 65 with the engagement groove 54.

[0019] The protruding pieces 24b, 25b have approximately the same protruding dimension as the vertical ridge 70 attached to the vertical frame bases 24a, 25a, and the inner surfaces 24c, 25c are approximately flat, with abutment surface fins (abutment surface) 67 at the base end. The abutment surface fins 67 are thin plate-like and protrude at approximately a right angle from the inner surfaces 24c, 25c of the protruding pieces 24b, 25b toward the inner vertical ridge engagement piece 65 located inside the room. The surface 67a located on the inner periphery of the abutment surface fins 67 has a dimension from the vertical projection wall 61 approximately the same as the protruding height of the inner vertical ridge engagement piece 65, and is configured to be located on the same plane as the protruding end surface 65a of the inner vertical ridge engagement piece 65. In the projecting pieces 24b, 25b having the above-described configuration, the portions of the inner surfaces 24c, 25c located on the tip side relative to the contact surface fin portions 67 form substantially flat opposing surface portions 24d, 25d.

[0020] The attachment 80 is attached to the inner surface 24c, 25c of the protruding pieces 24b, 25b. The attachment 80 holds the face material 21 between the vertical ridge 70 and the attachment 80, and is made of an extruded material made of a metal such as an aluminum alloy, as is the vertical ridge 70. In this embodiment, the attachment 80 has a seal mounting plate 81, an engagement groove 82, and an engagement plate 83. The seal mounting plate 81 is disposed along the opposing surface 24d, 25d of the protruding pieces 24b, 25b, and has a length approximately equal to the distance from the contact surface fin 67 to the protruding end edge of the protruding pieces 24b, 25b. The seal mounting plate 81 is provided with a seal mounting portion 84 on the visible surface of the protruding edge that faces the room. The seal mounting portion 84 is for mounting the dry outer seal member 6 on the portion facing the room, and is configured to have the same configuration as the seal mounting portion 48 provided on the clamping fin portions 22b, 23b of the horizontal frames 22, 23. The engagement groove 82 is a portion into which the abutment surface fin portion 67 is inserted when the seal mounting plate portion 81 is abutted against the opposing surface portions 24d, 25d of the protruding pieces 24b, 25b. The engagement plate portion 83 extends from the surface located on the outer periphery of the abutment surface fin portion 67 toward the room inside, and then extends at an angle toward the outer periphery. The engagement plate portion 83 is formed to have a dimension such that the extended edge portion can abut against the center vertical push edge engagement piece 66 when the seal mounting plate portion 81 is abutted against the opposing surface portions 24d, 25d of the protruding pieces 24b, 25b.

[0021] The above-mentioned attachment 80 is attached to the vertical frames 24, 25 with the extended edge of the engagement plate 83 abutting against the central vertical push edge engagement piece 66 and the abutment surface fin 67 inserted into the engagement groove 82, so that the seal mounting plate 81 abuts against the opposing surface 24d, 25d of the protruding pieces 24b, 25b. However, the attachment 80 to be attached to the vertical frames 24, 25 has a dimension that is twice as short as the dimension along the length of the vertical frames 24, 25 as the dimension along the top and bottom of the horizontal frames 22, 23.

[0022] The horizontal frames 22, 23 and vertical frames 24, 25 configured as described above are joined together by facing the small end of the horizontal frame 22, 23 to the surface 61b on the inner periphery of the vertical frame 24, 25 as shown in Figures 8 to 12, and screwing the mounting screws 90 into the screw holes 45 of the horizontal frames 22, 23 through the vertical frame 24, 25. In more detail, the vertical projection wall 62 located on the outer periphery of the vertical frame bases 24a, 25a has a screw through hole 62a through which the head 90a of the mounting screw 90 can be inserted, and the vertical projection wall 61 located on the inner periphery has a screw insertion hole 61a through which the shaft 90b of the mounting screw 90 can be inserted but the head 90a cannot be inserted. The screw through hole 62a and the screw insertion hole 61a are provided at positions that face the screw holes 45 of the horizontal frames 22, 23 when the sighting surface 43a of the horizontal frame bases 22a, 23a facing the room and the sighting surface 64a of the vertical frame bases 24a, 25a facing the room are positioned on the same plane. Therefore, when the mounting screw 90 passing through the screw through hole 62a is screwed into the four screw holes 45, the sighting surfaces 43a, 64a facing the room are positioned on the same plane, and the sighting surfaces of the horizontal frame bases 22a, 23a facing the outside of the room are abutted against the opposing surfaces 24d, 25d of the protruding pieces 24b, 25b. Furthermore, the small end portions of the horizontal frames 22, 23 located on the indoor side abut against the inner vertical edge engagement pieces 65 of the vertical frames 24, 25, while the portions located on the outdoor side abut against the abutment surface fin portions 67 of the vertical frames 24, 25. Therefore, the small end portions of the horizontal frames 22, 23 abut against the vertical frames 24, 25 in a stable state, eliminating concerns that problems such as the vertical frames 24, 25 becoming tilted relative to the horizontal frames 22, 23 may occur. Furthermore, the above-mentioned joining state is achieved by providing a contact surface fin portion 67 on the inner surfaces 24c, 25c of the protruding pieces 24b, 25b when molding the vertical frames 24, 25, while not providing a portion that protrudes beyond the abutment fin portion 67 into the interior of the room over the entire length of the opposing surface portions 24d, 25d on the inner surfaces 24c, 25c of the protruding pieces 24b, 25b, which are further towards the tip side than the abutment surface fin portion 67.This means that no processing such as cutting is required after molding the vertical frames 24, 25, and there is no concern that the manufacturing work will become complicated.

[0023] After the horizontal frames 22, 23 and the vertical frames 24, 25 are joined together, the face material 21 is placed on the inner peripheral portion with the outer seal members 6 attached to the seal mounting portions 48 of the horizontal frames 22, 23 and the seal mounting portions 48 of the attachment 80, respectively. If the horizontal ridges 50 are attached to the horizontal frames 22, 23 from this state, the face material 21 can be sandwiched between the clamping fin portions 22b, 23b and the horizontal ridges 50 via the outer seal member 6 and the inner seal member 5. Similarly, if the vertical ridges 70 are attached to the vertical frames 24, 25, the face material 21 can be sandwiched between the attachment 80 and the vertical ridges 70 via the outer seal member 6 and the inner seal member 5. As described above, the attachment 80 to which the outer sealing member 6 is attached is twice as long as the dimension along the top and bottom of the horizontal frames 22, 23 compared to the dimension along the length of the vertical frames 24, 25, so that it does not get in the way when the small end portions of the horizontal frames 22, 23 are abutted against the inner vertical edge engagement pieces 65 and abutment surface fin portions 67 of the vertical frames 24, 25.

[0024] Furthermore, in this embodiment, a resin spacer member 100 is interposed between the small end of the horizontal frame 22, 23 and the vertical projection wall portion 61 of the vertical frame 24, 25, to fill the gap between the small end of the horizontal frame 22, 23 and the vertical projection wall portion 61 located on the inner periphery side of the vertical frame base portion 24a, 25a. The spacer member 100 is formed by integrally molding a flange portion 110 and an insertion portion (second limiting portion) 120. The flange portion 110 is configured in a substantially rectangular shape with dimensions that can cover all the screw holes 45 provided in the horizontal frame base portion 22a, 23a and can simultaneously abut against the two horizontal projection wall portions 41, 42. Screw insertion holes 110a are formed in the portions of the flange portion 110 that correspond to the screw holes 45. The dimension of the flange portion 110 along the projection direction is set to a dimension that allows it to fit between the abutment surface fin portion 67 and the inner vertical press-edge engagement piece 65. As is clear from Figures 11 and 12, a recess 111 and a positioning protrusion (first limiting portion) 112 are provided in the flange portion 110 at a portion corresponding to the middle vertical press-edge engagement piece 66 of the vertical stile base portions 24a, 25a. The recess 111 is for accommodating the middle vertical press-edge engagement piece 66 so that the surface of the flange portion 110 can abut against the vertical projection wall portion 61 on the inner periphery side of the vertical stile base portions 24a, 25a. The positioning protrusion 112 restricts the relative movement of the spacer member 100 in the projection direction with respect to the vertical stiles 24, 25 by abutting against the side surface of the middle vertical edge engagement piece 66 located on the outside of the room when the flange portion 110 is abutted against the vertical projection wall portion 61 on the inner periphery side of the vertical stile base portion 24a, 25a between the abutment surface fin portion 67 and the inner vertical edge engagement piece 65. The insertion portion 120 is in the shape of a block configured to a dimension that allows it to be inserted into the hollow portion of the horizontal stile base portion 22a, 23a. The dimension of the insertion portion 120 in the projection direction is approximately the same as that of the flange portion 110. The dimension of the insertion portion 120 in the vertical direction is set so that it can abut against the peripheral walls of the screw holes 45 adjacent to each other on the top and bottom at the same time. An upper protrusion 121 and a lower protrusion 122 are provided in the portion of the insertion portion 120 between adjacent screw holes 45 in the projection direction so that they can simultaneously abut against the respective peripheral walls.

[0025] When the spacer member 100 is attached, the gap between the vertical projection wall portion 61 of the vertical frame 24, 25 and the small end of the horizontal frame 22, 23 is filled by the spacer member 100, so that it is possible to prevent a bending moment from occurring in the shaft portion 90b of the mounting screw 90. Furthermore, between the spacer member 100 and the vertical frame 24, 25, the position in the projection direction is determined by the positioning protrusion 112, and between the spacer member 100 and the horizontal frame 22, 23, the position in the projection direction and the sight direction is determined by fitting the insertion portion 120 into the hollow portion of the horizontal frame base portion 22a, 23a. As a result, the horizontal frame 22, 23 and the vertical frame 24, 25 can be easily and accurately joined by the spacer member 100, which makes it possible to facilitate the manufacturing work and improve the joining strength between the horizontal frame 22, 23 and the vertical frame 24, 25.

[0026] In the above-mentioned embodiment, the abutment surface fin portion 67 is provided so as to protrude from the inner surface 24c, 25c of the protruding piece 24b, 25b toward the vertical edge engagement piece 65, 66, but the present invention is not limited to this. For example, as shown in the modified example in Fig. 13 and Fig. 14, the abutment surface fin portion (abutment surface portion) 167 can be provided on the surface (inner peripheral surface) 61b of the vertical projection wall portion 61 on the inner peripheral side of the vertical frame base portion 24a, 25a of the vertical frame 124, 125. That is, in the modified example, the abutment surface fin portion 167 is provided from the portion between the protruding piece 24b, 25b and the vertical edge engagement piece 65, 66 on the surface 61b of the vertical frame base portion 24a, 25a in the same direction as the protruding piece 24b, 25b, and has the same protruding height as the vertical edge engagement piece 65, 66. The protruding edge of the contact surface fin portion 167 protrudes slightly toward the outside of the room. The protruding pieces 24b, 25b configure opposing surface portions 24d, 25d that are located on the tip side of the contact surface fin portion 67 on the inner surfaces 24c, 25c and are substantially flat.

[0027] The attachment 180 applied in this modification is configured with a seal mounting plate 181 and an engagement plate 182. The seal mounting plate 181 is arranged along the opposing surfaces 24d, 25d of the protruding pieces 24b, 25b. The seal mounting plate 181 is provided with a seal mounting portion 183 on the visible surface facing the interior of the room at the protruding edge. The seal mounting portion 183 is for mounting a dry outer seal member 6 on the portion facing the interior of the room. The engagement plate 182 is bent so as to gradually incline outward from the edge on the outer periphery of the seal mounting plate 181 toward the interior of the room, and then gradually inclines outward toward the exterior of the room, and can be attached between the protruding pieces 24b, 25b and the abutment surface fin portion 167. When the engagement plate 182 is brought into contact with the surface 61b, the seal mounting plate 181 is configured to have approximately the same protruding height as the protruding pieces 24b, 25b. The vertical protruding edge 70 used in the modified example has the same configuration as in the embodiment. In addition, the same reference numerals are used for the same configurations in the modified example as in the embodiment.

[0028] In the modified example constructed as above, the small ends of the horizontal frames 22, 23 and the vertical frames 24, 25 are extended in a direction perpendicular to the longitudinal direction, and the small ends of the horizontal frames 22, 23 are opposed to the inner peripheral surface 61b of the vertical frames 24, 25, and from this state, the horizontal frames 22, 23 and the vertical frames 24, 25 are joined together by screwing the mounting screws 90 into the screw holes 45 of the horizontal frames 22, 23 through the vertical frames 24, 25. At this time, the facing surfaces 43a, 64a of the horizontal frame bases 22a, 23a facing the room are positioned on the same plane, and the facing surfaces of the horizontal frame bases 22a, 23a facing the outside of the room are abutted against the facing surfaces 24d, 25d of the protruding pieces 24b, 25b. The small end portions of the horizontal frames 22, 23 located on the inside of the room abut against the inner vertical edge engagement pieces 65 of the vertical frames 24, 25, while the portions located on the outside of the room abut against the abutment surface fin portions 167 of the vertical frames 24, 25. Therefore, the small end portions of the horizontal frames 22, 23 abut against the vertical frames 24, 25 in a stable state, eliminating concerns that problems such as the vertical frames 24, 25 becoming tilted relative to the horizontal frames 22, 23 may occur. Moreover, the above-mentioned joining state is achieved by providing an abutment surface fin portion 167 on the surface 61b of the vertical frame base portions 24a, 25a when molding the vertical frames 24, 25, while not providing a portion that protrudes beyond the position of the abutment fin portion 67 toward the inside of the room over the entire length of the opposing surface portions 24d, 25d on the inner surfaces 24c, 25c of the protruding pieces 24b, 25b, which are further towards the tip side than the abutment surface fin portion 167. This means that no processing such as cutting is required after molding the vertical frames 24, 25, and there is no concern that the manufacturing work will become complicated.

[0029] In the above-mentioned embodiment and modified example, the door panel 20 is exemplified as the frame structure, but it can be applied to other things such as a sliding door for a hinged window, as long as it is constructed by joining a plurality of frame members. In addition, the frame structure is constructed with the first frame member being the vertical frame 24, 25 and the second frame member being the horizontal frame 22, 23, but the frame structure may be constructed with the first frame member being the horizontal frame 22, 23 and the second frame member being the vertical frame 24, 25, or it is also possible to construct the frame structure with either the first frame member or the second frame member being the central rail. Furthermore, the frame member is exemplified as being made of a metal such as an aluminum alloy, but it may be made of a resin or a composite structure of metal and resin. In addition, the spacer member is exemplified as being made of a resin, but it may be made of a metal such as a die cast.

[0030] In the above-mentioned embodiment and modified example, the attachment 80 is arranged on the protruding pieces 24b, 25b, but it is also possible to support the surface material without the attachment 80 by applying a wet type sealing material. Furthermore, the fittings are exemplified in which the protruding pieces 24b, 25b are arranged on the outside of the room, but the fittings may be configured to arrange the protruding pieces 24b, 25b on the inside of the room. Furthermore, the abutment surface fin portion 67 is exemplified as the abutment surface portion, which is a thin plate, but the abutment surface portion does not necessarily have to be a thin plate. In addition, since the horizontal and vertical frames are joined with the facing surfaces facing the room being located on the same plane, it is possible to ensure watertightness and airtightness between the frame body 10 by a series of seal materials 17, but the present invention is not limited to this.

[0031] Furthermore, in the above-mentioned embodiment, the second frame material is exemplified as a frame material configured to sandwich the surface material between the sandwiching fin portion and the ridge, but this is not necessarily limited to this. For example, it is also possible to form a sandwiching fin portion integrally on the indoor side of the horizontal frame base portion 22a, 23a, and to sandwich the surface material between the two sandwiching fin portions. Furthermore, the first frame material and the second frame material are exemplified as frames having hollow frame base portions 22a, 23a, 24a, 25a, but they do not necessarily have to be configured to have hollow portions.

[0032] As described above, the frame structure of the present invention is a frame structure constructed by joining a first frame member and a second frame member with the small end of the second frame member facing the inner surface of the first frame member, and is characterized in that a flange engagement piece for attaching a flange is provided protruding inwardly on one edge portion of the inner surface of the first frame member, and a protruding piece against which one outer surface of the second frame member can abut is provided on the other edge portion of the inner surface of the first frame member, the protruding piece protruding in the same direction as the flange engagement piece and having a protruding dimension larger than that of the flange engagement piece, and a contact surface portion against which the small end of the second frame member can abut is provided in the portion between the protruding piece and the flange engagement piece, corresponding to the protruding height of the flange engagement piece. According to this invention, since the first frame has an abutment surface between the protruding piece and the edge engagement piece, the small end of the second frame abuts against the abutment surface and the edge engagement piece, and the outer surface of the second frame can be opposed to the inner peripheral surface of the first frame while abutting against the protruding piece. Therefore, the first frame and the second frame can be joined in a stable state without performing any cutting or other processing on the first frame in advance, which makes it possible to facilitate the manufacturing process.

[0033] The present invention is further characterized in that, in the above-mentioned frame structure, the abutment surface portion protrudes toward the edge engagement piece from a position on the inner surface of the protruding piece corresponding to the protruding height of the edge engagement piece. According to this invention, the contact surface portion provided on the protruding piece can be brought into contact with the small end portion of the second frame member.

[0034] The present invention is further characterized in that, in the above-mentioned frame structure, the abutment surface portion protrudes from the inner surface of the first frame member in the same direction as the protruding piece and to the same protruding height as the edge engagement piece. According to this invention, the abutment surface portion provided on the inner peripheral surface of the first frame member can be abutted against the small end portion of the second frame member.

[0035] The present invention is also characterized in that, in the above-mentioned frame structure, a flat opposing surface portion is provided along the entire length of the first frame member on the inner surface of the protruding piece, which is located toward the tip side of the abutment surface portion, and the second frame member is joined to the first frame member with one outer surface abutting against the opposing surface portion and the small end portion abutting against the abutment surface portion and the edge engagement piece. According to this invention, since a flat opposing surface is provided on the inner surface of the protruding piece, the outer surface of the second frame can be abutted against this abutment plane. Therefore, the first frame and the second frame can be joined in a more stable state. The flat opposing surface does not necessarily have to be configured flat so that the entire surface is positioned on the same plane, and it is acceptable for it to have irregularities as long as the protruding height from the inner surface of the protruding piece (the protruding height toward the room side in the embodiment) is smaller than the abutment surface.

[0036] The present invention is also characterized in that, in the above-mentioned frame structure, an attachment having a sealing member attached thereto is arranged on the inner surface of the protruding piece of the first frame, and a ledge having a sealing member attached thereto is attached to the ledge engagement piece so as to face the attachment, and a surface material is sandwiched between the attachment and the ledge via the respective sealing members. According to this invention, it is possible to sandwich the face material between the seal member of the embossing and avoid direct contact between the face material and the protruding piece without using a wet seal member.

[0037] The present invention is also characterized in that, in the above-mentioned frame structure, a spacer member is arranged between the inner circumferential surface of the first frame member and the end of the second frame member so as to abut against these inner circumferential surface and the end of the second frame member. According to this invention, the inner peripheral surface and the fore-end portion can be brought into close contact with each other via the spacer member, which is advantageous in terms of bonding strength.

[0038] The present invention is also characterized in that, in the above-mentioned frame structure, the spacer member is provided with a first limiting portion which abuts against the first frame member to limit relative movement in a direction along the inner surface. According to this invention, by abutting the first limiting portion against the first frame, the positioning of the spacer member relative to the first frame can be easily carried out.

[0039] The present invention is also characterized in that, in the above-mentioned frame structure, the spacer member is provided with a second limiting portion which abuts against the second frame member to limit relative movement in a direction along the inner surface. According to this invention, by abutting the second limiting portion against the second frame, the positioning of the spacer member relative to the second frame can be easily carried out.

[0040] The present invention is also characterized in that, in the above-mentioned frame structure, the second frame has a hollow portion opening at the small end, and the second limiting portion is configured to fit into the hollow portion of the second frame. According to this invention, the relative movement of the second frame member with respect to the first frame member is restricted, making it possible to suppress misalignment and twisting after the frames are joined.

[0041] Furthermore, the building fixture of the present invention is characterized in that the first frame member is arranged in the vertical direction, the above-mentioned frame structure is arranged so as to be openable and closable relative to the frame body with the protruding piece positioned on the outside of the room, and the visible surface of the first frame member facing the interior of the room is arranged on the same plane as the visible surface of the second frame member facing the interior of the room. According to this invention, since the first frame has an abutment surface between the protruding piece and the edge engagement piece, the small end of the second frame abuts against the abutment surface and the edge engagement piece, and the outer surface of the second frame can be opposed to the inner peripheral surface of the first frame while abutting against the protruding piece. Therefore, the first frame and the second frame can be joined in a stable state without performing any cutting or other processing on the first frame in advance, which makes it possible to facilitate the manufacturing process.
