Description

Frame assembling structure and door and window

Technical Field

The present invention relates to a framing structure formed by joining a plurality of frame members, such as door sashes and the like, and a door and window provided with the framing structure.

Background

In a door sash of a door window including a vertical frame extending in a vertical direction and a horizontal frame extending in a horizontal direction, for example, a cutout end portion of the horizontal frame and a depth surface of the vertical frame are joined to each other in a state of facing each other. The vertical frame and the horizontal frame are provided with a clamping fin portion at one edge of the depth side on the inner peripheral side, and a bead is attached to the other edge, and the periphery of the surface material is clamped between the fin portion and the bead (see, for example, patent document 1).

Patent document 1: japanese patent laid-open publication No. 2010-150910.

Disclosure of Invention

However, a bead engaging piece for attaching the bead is provided to protrude from the depth surface of the vertical frame. Therefore, when the lateral frame and the vertical frame are directly joined together with the bead engagement piece provided, the joined state of the vertical frame and the lateral frame may become unstable, for example, in a posture in which the vertical frame is inclined with respect to the lateral frame. That is, the horizontal frame and the vertical frame are joined to each other in a state where only the clip engaging piece abuts against the cutout end portion of the horizontal frame. Therefore, in the conventional art, it is necessary to remove the bead engaging piece in the portion facing the cutout end portion of the horizontal frame in advance, which complicates the manufacturing work of the door sash. The above-described problem similarly occurs when the horizontal frame and the vertical frame are joined together with the kerf end portion of the vertical frame facing the depth surface of the horizontal frame.

In view of the above circumstances, an object of the present invention is to provide a sash structure and a door window, which can facilitate the manufacturing work.

In order to achieve the above object, a frame assembly structure according to the present invention is a frame assembly structure in which a first frame member and a second frame member are joined to each other in a state in which a cutout end portion of the second frame member is opposed to an inner peripheral surface of the first frame member, a bead engaging piece for attaching a bead is provided on an inner peripheral surface of the first frame member so as to project in an inner peripheral direction at a portion serving as one side edge of the inner peripheral surface, a projecting piece is provided on an inner peripheral surface of the first frame member so as to serve as the other side edge of the inner peripheral surface, an outer surface of one side of the second frame member is capable of abutting against the projecting piece, the projecting piece is provided so as to project in the same direction as the bead engaging piece and has a projecting dimension larger than that of the bead engaging piece, and an abutting surface portion is provided between the projecting piece and the bead engaging piece so as to correspond to a projecting height of the bead engaging piece, the cut end of the second frame member can abut against the abutting surface portion.

In the door/window according to the present invention, the first frame member is disposed in the vertical direction, and the projecting piece is disposed outside the room, the frame assembly structure is disposed so as to be openable and closable with respect to the side frame body, and a front view surface of the bead attached to the first frame member facing the room and a front view surface of the second frame member facing the room are disposed on the same plane as a front view surface of the first frame member facing the room.

According to the present invention, since the first frame member is provided with the abutting surface portion at the portion between the protruding piece and the bead engagement piece, the kerf end portion of the second frame member can be abutted against the abutting surface portion and the bead engagement piece and opposed to the inner peripheral surface of the first frame member in a state where the outer surface of the second frame member is abutted against the protruding piece. Therefore, the first frame member and the second frame member can be joined in a stable state without performing machining such as cutting on the first frame member in advance, and the manufacturing operation can be facilitated.

The lower frame base 12a is formed in a substantially hollow shape open on the lower surface, and the size thereof in the depth direction is substantially the same as that of the upper frame base 11 a. Frame screw holes 15 are provided in the hollow portions of the horizontal frames 11 and 12, respectively. The

vertical frames

13 and 14 have cross-sectional shapes substantially bilaterally symmetrical to each other, and are configured to have

vertical frame bases

13a and 14a formed in a hollow shape, and abutting

vertical fins

The door 20 is configured by attaching upper and lower horizontal frames (second frame members) 22 and 23 and left and right vertical frames (first frame members) 24 and 25 to the periphery of a surface member 21 such as a vertically rectangular glass plate. In the present embodiment, three hinges 1 are provided between the vertical frame 14 and the vertical frame 25 on the left side as viewed from the outdoor side, and the door 20 is supported so as to be able to rotate about these hinges 1 so as to project toward the outdoor side with respect to the side frame 10. The lock 2 is provided between the vertical frame 13 and the vertical frame 24 on the right side as viewed from the outdoor side, and the door handle 3 for unlocking the lock 2 is provided on the vertical frame 24 on the right side as viewed from the outdoor side. The

horizontal frames

22 and 23 and the

vertical frames

24 and 25 constituting the door 20 are extruded sections formed of metal such as aluminum alloy, and are each configured to have substantially the same cross-sectional shape over the entire length in the longitudinal direction.

The

lateral frames

22 and 23 have cross-sectional shapes substantially symmetrical to each other in the vertical direction, and are configured to have

lateral frame bases

22a and 23a formed in a hollow shape, and pinching

fins

22b and 23b protruding from the outdoor side edges of the

lateral frame bases

22a and 23a toward the inner peripheral side. As shown in fig. 5, the

horizontal frame bases

22a and 23a are surrounded by two horizontal

deep wall portions

41 and 42 and two horizontal

front wall portions

43 and 44 to form a substantially rectangular shape, and have screw holes 45 at the four corners of the hollow portion. The lateral

frame base portions

22a and 23a are provided with two lateral

bead engagement pieces

46 and 47 on the inner peripheral side of the lateral deep wall portion 41. The lateral

bead engagement pieces

46 and 47 are used to attach lateral beads 50 to the indoor side edges of the

lateral frame bases

22a and 23a, and project toward the inner peripheral side from the indoor side edge of the surface 41a of the lateral deep wall portion 41 and the substantially central portion of the lateral deep wall portion 41, respectively. A lateral bead engaging piece (hereinafter, referred to as an inner lateral bead engaging piece 46 when necessary) provided at an indoor side edge protrudes toward an inner peripheral side, and then a protruding edge thereof is bent at a substantially right angle toward the outside. A lateral bead engaging piece (hereinafter, referred to as a middle lateral bead engaging piece 47 when necessary) provided in the central portion is projected toward the inner peripheral side, and then the projected edge is bent toward the room at a substantially right angle. As is also apparent from the drawing, the projecting dimension of the middle lateral pressure bar engaging piece 47 and the inner lateral pressure bar engaging piece 46 is sufficiently smaller than the projecting dimension of the holding

fins

22b, 23b described later, and the projecting dimension of the middle lateral pressure bar engaging piece 47 is slightly smaller than the projecting dimension of the inner lateral pressure bar engaging piece 46. Specifically, for illustration, the projecting dimension of the middle lateral bead engaging piece 47 is set to about twice the thickness of the lateral frames 22 and 23, and the projecting dimension of the inner lateral bead engaging piece 46 is set to about three times the thickness of the lateral frames 22 and 23.

The lateral beads 50 attached to the lateral frames 22 and 23 by the lateral

bead engagement pieces

46 and 47 are extruded sections formed of metal such as aluminum alloy, and are configured to have substantially the same cross-sectional shape over the entire length in the longitudinal direction. As shown in fig. 2 and 5 (c), the lateral pressure bar 50 having the pressure bar base plate portion 51, the face material support plate portion 52, and the engaging plate portion 53 is applied to the present embodiment. The bead base plate portion 51 is disposed along the indoor-side transverse front wall portion 43 of the transverse

frame base portions

22a, 23 a. The surface material support plate portion 52 is bent at a substantially right angle from the inner peripheral edge of the bead base plate portion 51 toward the outside, and then further bent toward the outer peripheral side. A dry inner seal member 5 is attached to the extended edge of the face material support plate portion 52. The engagement plate portion 53 extends from the outer peripheral edge of the bead base plate portion 51 toward the outside and gradually inclines toward the outer peripheral side. An engaging groove 54 is provided at an outer corner portion of the bead base plate portion 51 and the engaging plate portion 53, and the curved portion of the inner lateral bead engaging piece 46 can be engaged with the engaging groove 54. The lateral beads 50 are attached to the

lateral frame bases

22a, 23a in a state of protruding from the indoor side portions of the

lateral frame bases

22a, 23a toward the inner circumferential side by inserting the extending edges of the engaging plate portions 53 between the middle lateral bead engaging pieces 47 and the lateral deep wall portions 41 and engaging the bent portions of the inner lateral bead engaging pieces 46 in the engaging grooves 54.

The pinching

wings

22b, 23b have substantially the same projecting dimension as the cross beads 50 attached to the

cross frame bases

22a, 23a, and have the sealing member attaching portion 48 on the front view side of the projecting edge facing the inside of the chamber. The sealing member mounting portion 48 is provided so as to protrude inward of the chamber from the front view surface of the pinching

fins

22b and 23b, and is used to mount the dry outer sealing member 6 on a portion facing the inside of the chamber.

The

vertical frames

24 and 25 have cross-sectional shapes substantially bilaterally symmetrical to each other, and are configured to have

vertical frame bases

24a and 25a formed in a hollow shape, and projecting

pieces

24b and 25b projecting from the outdoor side edges of the

vertical frame bases

24a and 25a toward the inner peripheral side. The

vertical frame bases

24a and 25a are surrounded by two vertical deep-

depth walls

61 and 62 and two vertical front-

view walls

63 and 64 to form a substantially rectangular shape. As is apparent from fig. 7, the

vertical frame bases

24a and 25a are configured such that the dimension in the depth direction is larger than the plate thickness of substantially one projecting

piece

24b or 25b of the

horizontal frame base

22a or 23a, and when the

front surfaces

43a and 64a facing the indoor space are placed on the same plane, the front surface 44a facing the outdoor space of the

horizontal frame base

22a or 23a can be brought into contact with the front surface (hereinafter, referred to as the

inner surfaces

24c and 25c of the projecting

pieces

24b and 25 b) facing the indoor space of the projecting

pieces

24b and 25 b. The

vertical frame bases

24a, 25a are provided with two vertical

bead engagement pieces

65, 66 on a surface (inner peripheral surface) 61b of the deep-depth wall portion 61 on the inner peripheral side thereof. The two vertical

bead engagement pieces

65, 66 are used to attach the vertical beads 70 to the indoor side edges of the

vertical frame bases

24a, 25a, and are constituted by the indoor side inner vertical bead engagement piece 65 and the central middle vertical bead engagement piece 66, similarly to the horizontal

bead engagement pieces

46, 47 provided to the

horizontal frames

22, 23. The projecting size of the middle longitudinal bead engaging piece 66 and the inner longitudinal bead engaging piece 65 is sufficiently smaller than the projecting size of the projecting

pieces

24b, 25b described later, and the projecting size of the middle longitudinal bead engaging piece 66 is slightly smaller than the projecting size of the inner longitudinal bead engaging piece 65. Specifically, for example, the projection dimension of the middle vertical bead engaging piece 66 is about twice the thickness of the

vertical frames

24 and 25, and the projection dimension of the inner vertical bead engaging piece 65 is about three times the thickness of the

vertical frames

24 and 25.

The vertical beads 70 attached to the

vertical frames

24 and 25 by the vertical

bead engagement pieces

65 and 66 are extruded sections formed of metal such as aluminum alloy, and are configured to have substantially the same cross-sectional shape over the entire length in the longitudinal direction. As shown in fig. 3 and 6, similar to the lateral beads 50, the vertical bead 70 having the bead base plate portion 71, the face material supporting plate portion 72, and the engaging plate portion 73 is applied to the present embodiment. An engaging groove 74 is provided in an outer corner portion of the bead base plate portion 71 and the engaging plate portion 73 of the longitudinal bead 70, and a bent portion of the inner longitudinal bead engaging piece 65 can be engaged with the engaging groove 74. A dry inner seal member 5 is attached to the extended edge of the surface material support plate portion 72. By inserting the front end of the engaging plate 73 between the middle vertical bead engaging piece 66 and the vertical deep wall portion 61 and engaging the curved portion of the inner vertical bead engaging piece 65 with the engaging groove 74, the vertical bead 70 is attached to the

vertical frame bases

24a, 25a in a state of protruding from the indoor side portions of the

vertical frame bases

24a, 25a toward the inner peripheral side.

The projecting

pieces

24b, 25b have substantially the same projecting dimensions as the vertical pressing bars 70 attached to the

vertical frame bases

24a, 25a, and

inner surfaces

24c, 25c thereof are formed substantially flat and have an abutment surface fin portion (abutment surface portion) 67 at a proximal end portion. The contact fin portion 67 is formed in a thin plate shape protruding from the

inner surfaces

24c and 25c of the protruding

pieces

24b and 25b at substantially right angles toward the inner vertical bead engaging piece 65 located on the indoor side. The dimension of the surface 67a on the inner peripheral side from the deep-depth wall portion 61 to the abutment surface fin portion 67 is substantially the same as the projecting height of the inner longitudinal bead engaging piece 65, and the surface 67a is configured to be on the same plane as the projecting end surface 65a of the inner longitudinal bead engaging piece 65. The projecting

pieces

24b and 25b having the above-described structure constitute substantially flat opposing

surface portions

24d and 25d in the portions of the

inner surfaces

24c and 25c located on the distal end side of the abutting wing portions 67.

The

tabs

24b, 25b mount an accessory 80 on the

inner surfaces

24c, 25 c. The attachment 80 is used to sandwich the surface material 21 between the longitudinal beads 70, and an extruded material formed of a metal such as an aluminum alloy is applied as in the case of the longitudinal beads 70. In the present embodiment, the attachment 80 having the sealing member mounting plate portion 81, the engaging groove 82, and the engaging plate portion 83 is applied. The seal member mounting plate portion 81 is disposed along the facing

surface portions

24d, 25d of the projecting

pieces

24b, 25b, and has substantially the same length as the distance from the contact surface fin portion 67 to the projecting end edges of the projecting

pieces

24b, 25 b. The seal member mounting plate portion 81 is provided with a seal member mounting portion 84 on a front view surface of a projecting edge thereof facing the inside of the chamber. The sealing member attachment portion 84 is used to attach the dry outer sealing member 6 to the portion facing the indoor space, and has the same configuration as the sealing member attachment portion 48 provided to the sandwiching

fins

22b, 23b of the lateral frames 22, 23. The engaging groove 82 is a portion into which the abutting fin 67 is inserted when the sealing member mounting plate 81 abuts the opposing

surface portions

24d and 25d of the projecting

pieces

24b and 25 b. The locking plate portion 83 extends from the surface located on the outer peripheral side of the abutting wing portion 67 toward the indoor side, and then extends obliquely toward the outer peripheral side. The engaging plate portion 83 is formed in such a size that when the seal member attaching plate portion 81 is brought into contact with the facing

surface portions

24d and 25d of the projecting

pieces

24b and 25b, the extended edge thereof can be brought into contact with the middle-vertical bead engaging piece 66.

The attachment 80 is attached to the

vertical frames

24 and 25 in a state where the seal member attaching plate portion 81 abuts the opposing

surface portions

24d and 25d of the projecting

pieces

24b and 25b by abutting the extending edge of the click plate portion 83 against the middle-vertical bar engaging piece 66 and inserting the abutting surface fin portion 67 into the click groove 82. Also, as the attachments 80 attached to the

vertical frames

24, 25, attachments 80 whose dimension is shorter than the longitudinal dimension of the

vertical frames

24, 25 by twice the vertical dimension of the

horizontal frames

22, 23 are applied.

In a state where the

horizontal frames

22 and 23 and the

vertical frames

24 and 25 configured as described above have their respective cutaway ends extending in the direction orthogonal to the longitudinal direction, as shown in fig. 8 to 12, the cutaway ends of the

horizontal frames

22 and 23 are opposed to the inner peripheral side surfaces 61b of the

vertical frames

24 and 25, and in this state, the mounting screws 90 are screwed into the screw holes 45 of the

horizontal frames

22 and 23 through the

vertical frames

24 and 25, respectively, to be joined to each other. More specifically, the deep-depth wall portion 62 located on the outer peripheral side of the

vertical frame bases

24a and 25a is formed with a screw insertion hole 62a through which the head portion 90a of the mounting screw 90 can be inserted, and the deep-depth wall portion 61 located on the inner peripheral side is formed with a screw insertion hole 61a through which the shaft portion 90b of the mounting screw 90 can be inserted and the head portion 90a cannot be inserted. The positions where the screw insertion holes 62a and the screw insertion holes 61a are provided are set to be portions facing the screw holes 45 of the

horizontal frames

22 and 23 when the indoor-facing main viewing surfaces 43a of the

horizontal frame bases

22a and 23a and the indoor-facing main viewing surfaces 64a of the

vertical frame bases

24a and 25a are on the same plane. Therefore, if the mounting screws 90 inserted through the screw insertion holes 62a are screwed into the four screw holes 45, the

front surfaces

43a and 64a facing the indoor space are positioned on the same plane, and the front surfaces of the

horizontal frame bases

22a and 23a facing the outdoor space are brought into contact with the facing

surface portions

24d and 25d of the projecting

pieces

24b and 25 b. Further, the slit end portions of the

horizontal frames

22, 23 are in contact with the inner vertical clip engaging pieces 65 of the

vertical frames

24, 25 at the portions located on the indoor side, and in contact with the contact surface fin portions 67 of the

vertical frames

24, 25 at the portions located on the outdoor side. Therefore, the kerf end portions of the

horizontal frames

22 and 23 can be in contact with the

vertical frames

24 and 25 in a stable state, and there is no concern about a problem such as the

vertical frames

24 and 25 being inclined with respect to the

horizontal frames

22 and 23. Further, the above-described joined state is achieved by providing the abutting surface fin portions 67 on the

inner surfaces

24c, 25c of the projecting

pieces

24b, 25b at the time of forming the

vertical frames

24, 25, and not providing the portions projecting beyond the abutting surface fin portions 67 toward the indoor side over the entire lengths of the opposing

surface portions

24d, 25d located on the front end side of the abutting surface fin portions 67 in the

inner surfaces

24c, 25c of the projecting

pieces

24b, 25b, and there is no need to perform machining such as cutting after forming the

vertical frames

24, 25, and there is no fear that the manufacturing operation becomes complicated.

After the lateral frames 22 and 23 and the

vertical frames

24 and 25 are joined to each other, the surface member 21 is disposed at the inner peripheral side portion in a state where the outer seal member 6 is mounted on the seal member mounting portions 48 of the lateral frames 22 and 23 and the seal member mounting portions 84 of the attachments 80, respectively. If the lateral pressure strips 50 are attached to the lateral frames 22 and 23 in this state, the surface material 21 can be sandwiched between the sandwiching

fins

22b and 23b and the lateral pressure strips 50 by the outer sealing member 6 and the inner sealing member 5. Similarly, if the vertical bead 70 is attached to the

vertical frames

24 and 25, the surface material 21 can be sandwiched between the attachment 80 and the vertical bead 70 by the outer seal member 6 and the inner seal member 5. As described above, since the dimension of the attachment 80 to which the outer seal member 6 is attached is twice as short as the dimension in the vertical direction of the lateral frames 22, 23 as compared with the dimension in the longitudinal direction of the

vertical frames

24, 25, the notch end portions of the lateral frames 22, 23 do not interfere with the contact between the inner vertical bead engaging pieces 65 of the

vertical frames

24, 25 and the wing surface portions 67.

Further, in the present embodiment, the gap generated between the cutout end portions of the

horizontal frames

22 and 23 and the deep wall portions 61 of the

vertical frames

24 and 25a located on the inner peripheral side of the vertical

frame base portions

24a and 25a is filled by interposing the resin-made packing member 100 between the cutout end portions of the

horizontal frames

22 and 23 and the deep wall portions 61 of the

vertical frames

24 and 25. The pad member 100 is integrally formed by the flange portion 110 and the insertion portion (second restriction portion) 120. The flange portion 110 is formed in a substantially rectangular shape having a dimension capable of covering the screw holes 45 provided in the entire lateral

frame base portions

22a, 23a and simultaneously abutting the two lateral

deep wall portions

41, 42. Screw insertion holes 110a are formed in the flange portion 110 at portions corresponding to the screw holes 45, respectively. The flange portion 110 is set to have a dimension in the depth direction so as to fit between the abutment surface fin portion 67 and the inner longitudinal bead engagement piece 65. As is apparent from fig. 11 and 12, in flange portion 110, a concave portion 111 and a positioning ridge (first regulating portion) 112 are provided at a portion corresponding to middle vertical bead engagement piece 66 of vertical

frame base portions

24a and 25 a. The recess 111 is for receiving the middle vertical bead engaging piece 66 so that the surface of the flange portion 110 can abut against the deep vertical wall portion 61 on the inner peripheral side of the

vertical frame bases

24a, 25 a. When the flange portion 110 is brought into contact with the longitudinal deep wall portion 61 on the inner peripheral side of the vertical

frame base portions

24a, 25a between the contact surface fin portion 67 and the inner longitudinal bead engagement piece 65, the positioning ridge 112 is brought into contact with the side surface of the middle longitudinal bead engagement piece 66 on the outdoor side, thereby restricting the relative movement of the gasket member 100 in the depth direction with respect to the

vertical frames

24, 25. The insertion portion 120 is a block having a size that can be inserted into the hollow portions of the horizontal

frame base portions

22a and 23 a. The dimension of insertion portion 120 in the depth direction is substantially the same as flange portion 110. The insertion portion 120 is set to have a dimension in the vertical direction so as to be able to simultaneously abut against the peripheral walls of the vertically adjacent screw holes 45. In the insertion portion 120, an upper protrusion 121 and a lower protrusion 122 are provided so as to simultaneously abut against the peripheral walls at a portion between the screw holes 45 adjacent in the depth direction.

When the above-described packing member 100 is mounted, the gap between the deep wall portion 61 of the

vertical frames

24 and 25 and the kerf end portions of the

horizontal frames

22 and 23 is filled with the packing member 100, and thus the shaft portion 90b of the mounting screw 90 can be prevented from generating a bending moment. Further, the position in the depth direction is defined by positioning ribs 112 between pad member 100 and

vertical frames

24 and 25, and the position in the depth direction and the position in the front view plane direction are defined by insertion portions 120 fitted into hollow portions of horizontal

frame base portions

22a and 23a between pad member 100 and

horizontal frames

22 and 23. As a result, the

horizontal frames

22 and 23 and the

vertical frames

24 and 25 can be easily and accurately joined by the spacer member 100, the manufacturing work can be facilitated, and the joining strength between the

horizontal frames

22 and 23 and the

vertical frames

24 and 25 can be improved.

In the above embodiment, the abutment wing portions 67 are provided so as to project from the

inner surfaces

24c, 25c of the projecting

pieces

24b, 25b toward the vertical

bead engaging pieces

65, 66, but the present invention is not limited thereto. For example, as in the modification shown in fig. 13 and 14, an abutment fin portion (abutment surface portion) 167 may be provided on a surface (inner peripheral surface) 61b of the deep-depth wall portion 61 on the inner peripheral side of the

vertical frame bases

24a and 25a of the

vertical frames

124 and 125. That is, in the modification, the contact surface fin 167 is provided on the surface 61b of the vertical

frame base portions

24a and 25a so as to have the same projecting height as the inner vertical bead engagement piece 65, and so as to face the same direction as the projecting

pieces

24b and 25b from the portion between the projecting

pieces

24b and 25b and the vertical

bead engagement pieces

65 and 66. The projecting edge of the abutment wing 167 projects slightly toward the outdoor side. The portions of the

inner surfaces

24c, 25c of the projecting

pieces

24b, 25b located on the tip side of the abutting wing 67 constitute substantially flat facing

surface portions

24d, 25 d.

The attachment 180 applied to this modification includes a seal member mounting plate portion 181 and a clip plate portion 182. The seal member mounting plate portion 181 is disposed along the facing

surface portions

24d, 25d of the projecting

pieces

24b, 25 b. In the seal member mounting plate portion 181, a seal member mounting portion 183 is provided on a front view surface of the projecting edge facing the inside of the chamber. The seal member attachment portion 183 is for attaching the dry outer seal member 6 to a portion facing the indoor space. The locking plate portion 182 is formed in a bent shape that gradually inclines outward from the outer peripheral edge of the sealing member mounting plate portion 181 toward the indoor side and then gradually inclines outward toward the outdoor side, and can be mounted between the protruding

pieces

24b and 25b and the contact fin portion 167. The sealing member mounting plate portion 181 is configured to have substantially the same projection height as the projecting

pieces

24b and 25b when the engagement plate portion 182 is brought into contact with the surface 61 b. The longitudinal beads 70 applied in the modification have the same structure as that of the embodiment. In the modification, the same components as those in the embodiment are denoted by the same reference numerals.

In the modification configured as described above, similarly, the slit ends of the

horizontal frames

22, 23 and the

vertical frames

24, 25 are opposed to the inner peripheral side surface 61b of the

vertical frames

24, 25 in a state where the slit ends of the

horizontal frames

22, 23 and the

vertical frames

24, 25 extend in the direction orthogonal to the longitudinal direction, and in this state, the mounting screws 90 are screwed into the screw holes 45 of the

horizontal frames

22, 23 and the

vertical frames

22, 25, respectively, to bring the

horizontal frames

22, 23 and the

vertical frames

24, 25 into a state of being joined to each other. At this time, the indoor-facing

main viewing surfaces

43a, 64a of the

horizontal frame bases

22a, 23a and the

vertical frame bases

24a, 25a are positioned on the same plane, and the outdoor-facing main viewing surfaces of the

horizontal frame bases

22a, 23a abut against the facing

surface portions

24d, 25d of the projecting

pieces

24b, 25 b. The portions of the kerf end portions of the

horizontal frames

22 and 23 located on the indoor side are in contact with the inner vertical stripe pressing engagement pieces 65 of the

vertical frames

24 and 25, and the portions located on the outdoor side are in contact with the contact surface fin portions 167 of the

vertical frames

24 and 25. Therefore, the slit ends of the lateral frames 22 and 23 can be abutted against the

vertical frames

24 and 25 in a stable state, and there is no concern about a problem that the

vertical frames

24 and 25 are inclined with respect to the lateral frames 22 and 23. Further, the above-described joined state is achieved by providing the abutting surface fin 167 on the front surface 61b of the

vertical frame bases

24a, 25a at the time of forming the

vertical frames

24, 25, and by not providing the portion projecting beyond the abutting surface fin 67 toward the indoor side over the entire length of the opposing

surface portions

24d, 25d located on the front end side of the abutting surface fin 167 in the

inner surfaces

24c, 25c of the projecting

pieces

vertical frames

In the above-described embodiment and modification, the door 20 is exemplified as the frame assembly structure, but the present invention can be applied to other articles such as a sash of a casement window as long as the door is configured by joining a plurality of frame members. Further, although the frame assembly structure is configured by the first frame members being the

vertical frames

24, 25 and the second frame members being the

horizontal frames

22, 23, the frame assembly structure may be configured by the first frame members being the

horizontal frames

22, 23 and the second frame members being the

vertical frames

24, 25, or the frame assembly structure may be configured by either the first frame member or the second frame member being the middle horizontal frame. Further, the frame material is made of metal such as aluminum alloy, but may be made of resin or a composite of metal and resin. Further, a resin material is exemplified as the pad member, but it may be made of metal such as die cast.

In the above-described embodiment and modification, the attachment 80 is disposed on the projecting

pieces

24b and 25b, but the attachment 80 may be omitted to support the surface material by applying a wet seal as a sealing member. Further, although the window and door is illustrated as being disposed such that the projecting

pieces

24b and 25b are located on the outdoor side, the window and door may be configured such that the projecting

pieces

24b and 25b are disposed on the indoor side. Further, although the thin-plate-shaped abutting surface fin portion 67 is exemplified as the abutting surface portion, the abutting surface portion does not necessarily need to be thin-plate-shaped. Further, since the horizontal frame and the vertical frame are joined in a state where the front surfaces facing the inside of the room are positioned on the same plane, the water-tightness and the air-tightness with respect to the side frame 10 can be ensured by the single continuous tightening member 17, but the present invention is not limited thereto.

Further, in the above-described embodiment, the structure in which the face material is sandwiched between the sandwiching fin portion and the bead is exemplified as the second frame material, but the structure is not necessarily limited thereto. For example, a pinching fin portion may be formed integrally with the indoor side of the horizontal

frame base portions

22a and 23a, and the surface material may be pinched between the two pinching fin portions. Further, although the first frame member and the second frame member are illustrated as frame members having

hollow frame bases

22a, 23a, 24a, and 25a, the first frame member and the second frame member do not necessarily have to be configured to have a hollow portion.

As described above, the present invention relates to a frame assembly structure in which a first frame member and a second frame member are joined to each other in a state in which a cutout end portion of the second frame member faces an inner peripheral surface of the first frame member, a bead engaging piece for attaching a bead is provided on an inner peripheral surface of the first frame member so as to project in an inner peripheral direction at a portion serving as one side edge of the inner peripheral surface, a projecting piece is provided on an inner peripheral surface of the first frame member so as to project in the same direction as the bead engaging piece and have a projecting dimension larger than that of the bead engaging piece at a portion serving as a portion between the projecting piece and the bead engaging piece so as to be capable of abutting against the projecting piece is provided on an outer surface of one side of the second frame member so as to correspond to a projecting height of the bead engaging piece, the cutout end portion of the second frame member can abut against the abutting surface portion.

According to the present invention, since the first frame member is provided with the abutting surface portion at the portion between the projecting piece and the bead engagement piece, the cutout end portion of the second frame member can be made to abut against the abutting surface portion and the bead engagement piece, and can be made to face the inner peripheral surface of the first frame member in a state where the outer surface of the second frame member abuts against the projecting piece. Therefore, the first frame member and the second frame member can be joined in a stable state without performing machining such as cutting on the first frame member in advance, and the manufacturing operation can be facilitated.

In the above-described frame assembly structure, the abutting surface portion protrudes toward the bead engaging piece from a position on the inner surface of the protruding piece corresponding to the protruding height of the bead engaging piece.

According to the present invention, the abutting surface portion provided on the projecting piece can abut on the kerf end portion of the second frame member.

In the above-described frame assembling structure, the abutting surface portion may be projected in the same direction as the projecting piece and at the same projecting height as the bead engaging piece from the inner peripheral surface of the first frame member.

According to the present invention, the abutting surface portion provided on the inner peripheral surface of the first frame member can abut on the cutout end portion of the second frame member.

In the above-described frame assembly structure, the flat opposing surface portion extending over the entire length of the first frame member is provided on the inner surface of the projecting piece at a portion located at the distal end side of the abutting surface portion, and the second frame member is joined to the first frame member with one outer surface thereof abutting against the opposing surface portion and with the cutout end abutting against the abutting surface portion and the bead engaging piece.

According to the present invention, since the flat facing surface portion is provided on the inner surface of the projecting piece, the outer surface of the second frame member can be brought into contact with the contact plane. Thus, the first frame member and the second frame member can be joined in a more stable state. The flat facing surface portion does not necessarily have to be configured so that the entire surface thereof is flush with the same plane, and there is no problem if the height of projection from the inner surface of the projecting piece (the height of projection toward the indoor side in the embodiment) is smaller than the contact surface portion.

In the above-described frame assembly structure, the attachment to which the seal member is attached is disposed on the inner surface of the projecting piece, the bead to which the seal member is attached to the bead engagement piece so as to face the attachment, and the surface material is sandwiched between the attachment and the bead by the seal members.

According to the present invention, the surface material can be held between the projecting piece and the sealing member of the bead without applying a wet sealing member and without bringing the surface material into direct contact with the projecting piece.

In the above-described frame assembly structure, a spacer member is disposed between the inner peripheral surface of the first frame member and the slit end of the second frame member so as to abut against the inner peripheral surface and the slit end.

According to the present invention, the inner peripheral surface can be tightly connected to the kerf end portion by the packing member, which is advantageous in the point of joining strength.

In the above-described frame assembly structure, the spacer member may be provided with a first regulating portion that regulates relative movement of the first frame member in a direction along the inner peripheral surface by abutting against the first frame member.

According to the present invention, the first regulating portion can be brought into contact with the first frame member, whereby the positioning of the spacer member with respect to the first frame member can be performed more easily.

In the above-described frame assembly structure, the spacer member may be provided with a second regulating portion that regulates relative movement of the second frame member in a direction along the inner peripheral surface by abutting against the second frame member.

In the above-described frame assembly structure, the second frame member has a hollow portion that opens at the cutout end portion, and the second restriction portion is configured to be fitted into the hollow portion of the second frame member.

According to the present invention, since the relative movement of the second frame member with respect to the first frame member is restricted, the deviation or distortion generated after the joining of these frame members can be suppressed.

In the door/window according to the present invention, the first frame member is disposed in the vertical direction, and the projecting piece is disposed outside the room, and the first frame member is disposed on the side frame body so as to be openable and closable, and the front surface of the first frame member facing the room is disposed on the same plane as the front surface of the second frame member facing the room.

According to the present invention, since the abutting surface portion is provided in the first frame member at the portion between the protruding piece and the bead engaging piece, the kerf end portion of the second frame member can be abutted against the abutting surface portion and the bead engaging piece and opposed to the inner peripheral surface of the first frame member in a state where the outer surface of the second frame member is abutted against the protruding piece. Thus, the first frame member and the second frame member can be joined in a stable state without performing machining such as cutting on the first frame member in advance, and the manufacturing operation can be facilitated.
