Summary of the Invention

Problems to be Solved by the Invention

[0004] The problem to be solved by the present invention is to provide a vertical frame member that can be used not only for flush-mounted installations but also for other types of attachments and can be stably attached.

Means for Solving the Problems

[0005] The reference numerals shown in the following parentheses are referred to in FIGS. 1 to 16.

[0006] To solve the above problems, according to claim 1, the vertical frame member (1) comprises a frame body (10) and a support member (40) attached to the frame body (10), wherein the frame body (10) comprises a strip portion (11) provided in the shape of a strip having a width in the depth direction, a thickness in the visible direction, and a length in the vertical direction, and a convex piece portion (20) integrally formed with the strip portion (11), protruding in the depth direction from the side end of the strip portion (11) in the depth direction, and having a thickness thinner than the thickness of the strip portion (11), and the strip portion (11) However, the strip portion (11) has a groove (16) extending in the longitudinal direction on its side end surface (14) in the depth direction, and the support material (40) has an insertion portion (41) that is inserted into the groove (16), and a projection portion (42) that is integrally formed with the insertion portion (41) and protrudes from the groove (16), and the convex piece portion (20) protrudes from the side end of the strip portion (11) in the depth direction beyond the tip end surface (43) of the projection portion (42), and a gap (48) is formed between the projection portion (42) and the convex piece portion (20).

[0007] According to claim 1 as described above, since the convex piece (20) protrudes in the depth direction from the side end of the strip portion (11) beyond the tip end surface (43) of the protruding portion (42), when the support material (40) is removed from the frame body (10), the convex piece (20) protrudes from the wall surface and an offset is achieved between the wall surface and the end of the convex piece (20). Since the thickness of the protruding piece (20) is thinner than the thickness of the strip portion (11), when the support material (40) is removed from the frame body (10), a soffit-type fitting can be achieved in which the protruding piece (20) appears thinner. As the insertion piece of the support material (40) is inserted into the groove (16), the bending of the convex piece (20) is suppressed by the insertion piece (41). The convex piece (20) bends when it comes into contact with the projection (42), but any further bending of the convex piece (20) is suppressed by the projection (42). Therefore, the insertion piece (41) and projection (42) of the support material (40) contribute to preventing damage to the convex piece (20). Since the protruding piece (20) extends beyond the tip surface (43) of the projection (42) and protrudes from the side edge of the strip portion (11) in the depth direction, a mounting space for an auxiliary frame material or trim material is formed on the back of the protruding piece (20). By combining the auxiliary frame material or trim material with the protruding piece (20), a finish can be achieved that makes the frame body (10) appear thicker. Since the protruding piece (20) is supported by the auxiliary frame material or trim material, damage to the protruding piece (20) is prevented. When the strip portion (11) is placed against the mounting surface along the vertical edge of the wall opening and the vertical frame member (1) is attached to the vertical edge of the opening, the protruding portion (42) of the support member (40) is also placed against the mounting surface. Thus, the mounting of the support member (40) and the frame body (10) becomes stable. Since the gap (48) is precisely formed between the protruding portion (42) and the convex piece (20), the projection formed on the auxiliary frame material or trim material can be inserted into the gap (48). This contributes to the stable installation of the auxiliary frame material or trim material.

[0008] According to claim 2, in the vertical frame member (1) described in claim 1, the strip portion (11) has a flat concealed surface (12) on its surface that faces the visible direction, the protruding portion (42) bulges out from the groove (16) and the insertion portion (41) toward the concealed surface (12), and the protruding portion (42) has a second concealed surface (44) on the surface of its bulging portion that faces the same direction as the concealed surface (12) and is provided flush with the concealed surface (12).

[0009] According to claim 2 as described above, since the second concealed surface (44) is provided flush with the concealed surface (12), when the concealed surface (12) is brought into contact with the mounting surface along the vertical edge of the opening in the wall and the vertical frame member (1) is attached to the vertical edge of the opening, the second concealed surface (44) is also brought into contact with the mounting surface. Therefore, the attachment of the support member (40) and the frame body (10) is stabilized.

[0010] According to claim 3, in the vertical frame member (1) described in claim 2, the recess (46) is formed between the visible / hidden surface (12) and the second visible / hidden surface (44).

[0011] According to claim 3 described above, when a thin piece such as a flathead screwdriver or blade is inserted into the recess (46) and a load in the forward direction is applied to the protruding part (42) by the thin piece, the insertion part (41) is pulled out of the groove (16). This contributes to the easy removal of the support material (40).

[0012] According to claim 4, in the vertical frame member (1) described in claim 2 or 3, the strip portion (11) and the protruding piece portion (20) have a flat visible surface (13) on their surface that faces in the direction opposite to the direction in which the visible / hidden surface (12) faces. It holds.

[0013] According to claim 5, the vertical frame member (1) described in claim 1 further comprises a second support member (50) attached to the frame body (10), the frame body (10) is integrally formed with the strip portion (11), and further comprises a second convex portion (21) which protrudes from the side end of the strip portion (11) opposite to the side end in the direction opposite to the protruding direction of the convex portion (20) and has a thickness thinner than the thickness of the strip portion (11), and the strip portion (11) has a front side end face (15) opposite to the side end face (14) of the strip portion (11). The second support material (50) has a second groove (17) extending in the longitudinal direction, and the second support material (50) has a second insertion portion (51) that is inserted into the second groove (17), and a second projection portion (52) that is integrally formed with the second insertion portion (51) and protrudes from the second groove (17), and the second convex piece portion (21) protrudes in the opposite direction to the protrusion direction of the convex piece portion (20) beyond the tip end surface (53) of the second projection portion (52), and a second gap (58) is formed between the second projection portion (52) and the second convex piece portion (21).

[0014] According to claim 6, in the vertical frame member (1) described in claim 5, the strip portion (11) has a flat concealed surface (12) on its surface facing the visible direction, the protruding portion (42) bulges out from the groove (16) and the insertion portion (41) toward the concealed surface (12), the protruding portion (42) has a second concealed surface (44) on the surface of its bulging portion that faces the same direction as the concealed surface (12) and is provided flush with the concealed surface (12), the second protruding portion (52) bulges out from the second groove (17) and the second insertion portion (51) toward the concealed surface (12), the second protruding portion (52) has a third concealed surface (54) on the surface of its bulging portion that faces the same direction as the concealed surface (12) and is provided flush with the concealed surface (12).

Mode for Carrying Out the Invention

[0019] Hereinafter, embodiments will be described with reference to the drawings. The features and technical effects of the embodiments will be understood from the following detailed description and the drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. Since the drawings are provided for illustrative purposes only, the scope of the present invention is not limited to the illustrations in the drawings.

[0020] <1. Vertical Frame Member> Figure 1 is a cross-sectional view of the vertical frame member 1. Figure 2 is an enlarged view of region II shown in Figure 1. Figure 3 is an enlarged view of region III shown in Figure 1.

[0021] The rectangular opening into which the vertical frame member 1 is installed is formed in the wall of the building. The pair of vertical edges of the opening are vertical, and the upper and lower horizontal edges of the opening are horizontal. The wall into which the opening is formed is either a partition wall or an exterior wall. A partition wall is a wall that divides an indoor space. An exterior wall is a wall that separates an indoor space from an outdoor space.

[0022] The vertical frame member 1 is installed on the vertical edge of the opening. The cross-sections shown in Figures 1 to 3 are perpendicular to the depth direction and the face direction. Here, depth refers to the width dimension of a member such as the vertical frame member 1, the depth direction refers to the depth direction of the opening, and the depth direction is parallel to the wall thickness direction. Face refers to the thickness dimension of a member such as the vertical frame member 1, and the face direction refers to the direction parallel to the width direction of the opening. The direction perpendicular to the depth direction and the face direction is called the vertical direction.

[0023] The vertical frame member 1 is provided in the shape of a thin, elongated plate having a width in the depth direction, a thickness in the visible direction, and a length in the vertical direction. The horizontal cross-sectional shape of the vertical frame member 1, that is, the cross-sectional shape perpendicular to the vertical direction, is uniform from the top end to the bottom end of the vertical frame member 1 and is symmetrical in the depth direction.

[0024] The vertical frame member 1 comprises a frame body 10 and two support members 40 and 50 attached to the frame body 10.

[0025] The frame body 10 is provided in the shape of a thin plate in the visible direction and long in the vertical direction, having a width in the depth direction, a thickness in the visible direction, and a length in the vertical direction. The overall length of the frame body 10 is sufficiently greater than the overall width of the frame body 10, and the overall width of the frame body 10 is greater than the overall thickness of the frame body 10. The horizontal cross-sectional shape of the frame body 10 is uniform from the top end to the bottom end of the frame body 10.

[0026] The frame body 10 is made of wood or resin, or a mixture of resin and wood fiber material. The mixture material may be, for example, medium-density fiberboard (MDF), hardboard, particleboard, extruded or injection-molded products. A decorative sheet may be attached to all or part of the surface of the frame body 10.

[0027] The frame body 10 has a strip portion 11 and two protruding portions 20 and 21. The strip portion 11 and the protruding portions 20 and 21 are integrally formed. The strip portion 11 has a width in the depth direction, a thickness in the visible direction, and a length in the vertical direction, and is formed in the shape of a thin strip in the visible direction and long in the vertical direction. The strip portion 11 has a flat, visible / hidden surface 12 on its surface that faces the visible direction. When the vertical frame member 1 is attached to the vertical edge of the opening, the visible / hidden surface 12 faces the inner surface of the opening along the vertical edge of the opening. The visible / hidden surface 12 forms an external corner with each of the side end faces 14 and 15 of the strip portion 11 in the depth direction.

[0028] The protruding pieces 20 and 21 project in opposite directions in the depth direction from each of the two ends of the strip portion 11 in the depth direction. The protruding pieces 20 and 21 and the strip portion 11 have a common depth surface 13 on their surfaces. The depth surface 13 is formed flat. The depth surface 13 faces in the opposite direction to the direction of the concealed surface 12. The depth surface 13 is parallel to the concealed surface 12. Because the depth surface 13 faces inward into the opening, the depth surface 13 is the design surface (visible surface). The depth surface 13 faces the vertical edge opposite to the vertical edge to which the vertical frame material 1 is attached. The distance from the depth surface 13 to the concealed surface 12 corresponds to the thickness of the strip portion 11, as well as the overall thickness of the vertical frame material 1 and the frame body 10. The protruding pieces 20 and 21 are formed in a strip shape with a thickness thinner than the thickness of the strip portion 11.

[0029] The end faces 22 and 23 of the protruding portions 20 and 21 in the depth direction are both the visible surface and the design surface. A chamfer 18 is formed at the corner between the end face 22 of the protruding portion 20 and the depth surface 13. Similarly, a chamfer 19 is formed at the corner between the end face 23 of the protruding portion 21 and the depth surface 13. Chamfers 24 and 25 are angular chamfers. However, chamfers 24 and 25 may also be rounded chamfers.

[0030] The protruding portion 20 has a flat back surface 26 on the surface opposite to the visible surface 13. The back surface 26 faces the same direction as the visible / hidden surface 12 and the opposite direction to the visible surface 13. The distance from the visible surface 13 to the back surface 26 corresponds to the thickness of the protruding portion 20. The back surface 26 and the end surface 22 form an outer corner. Just as the protruding portion 20 has a back surface 26, the protruding portion 21 has a flat back surface 27 on the surface opposite to the visible surface 13.

[0031] In the direction of projection, the side end face 14 of the strip portion 11 and the back surface 26 of the protruding piece portion 20 form an inside corner. The opposite side end face 15 and the back surface 27 of the protruding piece portion 21 form an inside corner.

[0032] The frame body 10 has grooves 16 and 17 formed on the side end faces 14 and 15 of the strip portion 11, respectively. The grooves 16 and 17 extend vertically from the upper end to the lower end of the frame body 10 and the strip portion 11. The grooves 16 and 17 are rectangular in shape in a cross section perpendicular to the vertical direction. The grooves 16 and 17 are slightly separated from the back surfaces 26 and 27 of the protruding pieces 20 and 21 toward the concealed surface 12, for example, by about 1 mm. There is a step between the inner surface 18 of the groove 16 that is closer to the visible surface 13 and the back surface 26 of the protruding piece 20, and there is a step between the inner surface 19 of the groove 17 that is closer to the visible surface 13 and the back surface 27 of the protruding piece 21. However, the inner surface 18 of the groove 16 and the back surface 26 of the protruding piece 20 may be flush, and the inner surface 19 of the groove 17 and the back surface 27 of the protruding piece 21 may be flush.

[0033] The support materials 40 and 50 are made of wood or resin, or a mixture of resin and wood fiber. The mixture may be MDF. The support materials 40 and 50 may be molded products such as extruded or injection molded products. The composition or raw materials of the support materials 40 and 50 may be changed to rigid fiberboard or particleboard, etc. The horizontal cross-sectional shape of the support materials 40 and 50 is uniform from the top end to the bottom end of the vertical frame material 1.

[0034] The support material 40 is partially inserted into the groove 16 and partially protruding from the groove 16. In other words, the support material 40 has an insertion portion 41 that is inserted into the groove 16 and a protruding portion 42 that protrudes from the groove 16.

[0035] The insertion portion 41 and the protruding portion 42 are integrally formed. The support material 40 is held to the frame body 10 by inserting the insertion portion 41 into the groove 16. The insertion portion 41 can be removed from the groove 16. The removed insertion portion 41 can be reinserted into the groove 16.

[0036] When the insertion portion 41 is inserted into the groove 16, the protruding portion 42 is positioned in the inner corner formed by the side end surface 14 of the strip portion 11 and the back surface 26 of the convex piece portion 20. The protruding portion 42 does not extend to the end surface 22 of the convex piece portion 20, and the flat tip surface 43 of the protruding portion 42 is positioned between the end surface 22 of the convex piece portion 20 and the side end surface 14 of the strip portion 11 in the depth direction. In other words, the convex piece portion 20 protrudes in the depth direction from the side end of the strip portion 11 in the depth direction, beyond the tip surface 43 of the protruding portion 42.

[0037] The protruding portion 42 bulges out from the groove 16 and the insertion portion 41 toward the visible / hidden surface 12 of the strip portion 11, and the bulging portion is in contact with the side end surface 14 of the strip portion 11. The protruding portion 42 has a flat visible / hidden surface 44 on the surface of the bulging portion that is oriented in the same direction as the visible / hidden surface 12 of the strip portion 11. The visible / hidden surface 44 of the insertion portion 41 and the visible / hidden surface 12 of the strip portion 11 are flush. A recess 46 is formed between the visible / hidden surface 44 of the insertion portion 41 and the visible / hidden surface 12 of the strip portion 11. Specifically, the insertion portion 41 has a notch in the region between the surface 45 of the insertion portion 41 that is in contact with the side end surface 14 of the strip portion 11 and the visible / hidden surface 44 of the insertion portion 41, and this notch is the recess 46. When a thin piece, such as a flathead screwdriver or a blade, is inserted into the recess 46 and a load in the forward direction is applied to the protruding portion 42 by the thin piece, the insertion portion 41 is pulled out of the groove 16.

[0038] The insertion portion 41 is positioned away from the protruding piece 20 in the visible direction on the back side of the protruding piece 20, and a gap 48 is formed between the insertion portion 41 and the protruding piece 20. The insertion portion 41 has a notch in the region between the surface 47 of the insertion portion 41 that is in contact with the back surface 26 of the protruding piece 20 and the visible / hidden surface 44 of the insertion portion 41, and this notch forms the gap 48.

[0039] The horizontal cross-sectional shape of the support material 50 is symmetrical with respect to the horizontal cross-sectional shape of the support material 40. The insertion portion 51, projection portion 52, tip surface 53, visible / hidden surface 54, surface 55 and surface 57 of the support material 50 correspond to the insertion portion 41, projection portion 42, tip surface 43, visible / hidden surface 44, surface 45 and surface 47 of the support material 40, respectively. The recess 56 and gap 58 correspond to the recess 46 and gap 48, respectively.

[0040] <2. Fitting> A mounting structure using one or more vertical frame members 1 will be described below. In the following description, the wall is a partition wall or exterior wall of a building constructed by the wood panel adhesive method. However, the wall may also be a partition wall or exterior wall of a building constructed by the post-and-beam construction method or the framed wall construction method. The wall may also be a structural wall. A structural wall is a structure in which gypsum board is attached to one or both sides of a framework made of wood or lightweight steel.

[0041] (1) Hachikake-sagari As shown in Figure 4, the wall is mainly composed of wall panels 70, which are structural materials. The wall panels 70 are made of wood. The wall panels 70 have a pair of vertical frame members 71, a pair of horizontal frame members connected between the upper and lower ends of the vertical frame members 71, and face materials 72, 73 attached to both sides of the frame made up of the vertical frame members 71 and the horizontal frame members. The wall panels 70 may have one or more wooden auxiliary battens assembled to the frame on the inside of the frame. The wall panels 70 may have insulation material filled on the inside of the frame. In Figure 4, a single vertical frame member 71 is shown, and this vertical frame member 71 runs along one of the vertical edges of an opening 80 formed in the wall.

[0042] A wall is formed by joining multiple wall panels 70 so as to surround the opening 80. Wooden timbers, called mullions 74, are erected on both sides of the opening 80 and joined to the side edges of the wall panels 70. The mullions 74 are adjustment members used to adjust the width of the opening 80 to the design value. A strip-shaped board 79 is attached to the face of the mullion 74 that faces inward towards the opening 80. The board 79 is, for example, gypsum board or plywood. The board 79 may also be fire-resistant. The board 79 forms the inner surface of the opening 80 along its vertical edges. Alternatively, the mullions 74 may be omitted, and the board 79 may be attached to the side edges of the wall panels 70.

[0043] The support materials 40 and 50 have been removed from the frame body 10. The visible / hidden surface 12 of the strip portion 11 is facing the board 79 and in contact with the board 79, and the frame body 10 is fixed to the inner surface of the opening 80 by fasteners 77 and 78, such as finish nails or screws, being driven into the frame body 10 from both wall surfaces of the wall. The visible / hidden surface 12 of the strip portion 11 may also be bonded to the inner surface of the opening 80. The visible / hidden surface 12 of the strip portion 11 may also be joined to the inner surface of the opening 80 by using fasteners 77 and 78 in combination with adhesive.

[0044] Alternatively, the mullions 74 and boards 79 may be omitted, the visible / hidden surface 12 of the strip portion 11 may be in contact with the side end surface of the wall panel 70, and the frame body 10 may be fixed to the side end surface of the wall panel 70 by fasteners 77 and 78.

[0045] The width of the strip portion 11 in the depth direction is equal to the thickness of the wall. The side end faces 14 and 15 of the strip portion 11 are flush with both wall surfaces of the wall.

[0046] Boards 75 and 76 are attached to the respective wall surfaces of the wall. Boards 75 and 76 may have cloth attached to their surfaces. Boards 75 and 76 protrude into the inner surface of the opening, that is, from board 79 into the opening. These protruding portions are in contact with the side end surfaces 14 and 15 of the strip portion 11, respectively, and grooves 16 and 17 are hidden behind these protruding portions. These protruding portions may be bonded to the side end surfaces 14 and 15 of the strip portion 11. Grooves 16 and 17 may be filled with a filler such as resin.

[0047] The side edges of boards 75 and 76 are abutted against the back surfaces 26 and 27 of the protruding pieces 20 and 21. The side edges of boards 75 and 76 may also be bonded to the back surfaces 26 and 27 of the protruding pieces 20 and 21.

[0048] The thickness of the board 75 is less than the protrusion width of the protruding piece 20 from the side end face 14 of the strip portion 11 to the end face 22 of the protruding piece 20, and the protruding piece 20 protrudes further in the depth direction than the board 75. A step is formed between the surface of the board 75 and the end face 22 of the protruding piece 20. Similarly, the thickness of the board 76 is smaller than the protrusion width of the protruding piece 21 from the side end face 15 of the strip portion 11 to the end face 23 of the protruding piece 21, and the protruding piece 21 extends outward from the board 76.

[0049] Furthermore, as shown in (2) below, the board 75 may not protrude from the inner surface of the opening, that is, from the board 79 into the opening, and the side end surface of the board 75 may be separated from the back surface 26 of the convex piece 20. This will be explained in detail below.

[0050] (2) Finishing using trim As shown in Figure 5, the support material 40 is not removed, and the support material 40 is held in place by the insertion portion 41 of the support material 40 being inserted into the groove 16. The protruding portion 42 of the support material 40 is positioned in the area between the side end face of the board 75 and the back surface 26 of the convex piece 20.

[0051] The side end face of the board 75 is in surface contact with the protruding portion 42 of the support material 40, particularly the visible / hidden surface 42. The side end face of the board 75 may be joined to the protruding portion 42 by adhesive or double-sided adhesive tape. The surface of the board 75 and the protruding end face 43 of the protruding portion 42 are flush.

[0052] The trim piece 91 fits into the inner corner formed by the protruding end surface 43 of the projection 42 and the back surface 26 of the convex piece 20. The trim piece 91 extends vertically along the convex piece 20. The horizontal cross-sectional shape of the trim piece 91, that is, the cross-sectional shape perpendicular to the vertical direction, is rectangular, and this cross-sectional shape is uniform from the top end to the bottom end of the trim piece 91. The dimension of the trim piece 91 in the visible direction is larger than the dimension of the trim piece 91 in the depth direction.

[0053] The trim piece 91 makes surface contact with the back surface 26 of the protruding piece 20. The trim piece 91 may be joined to the back surface 26 of the protruding piece 20 by adhesive or double-sided adhesive tape. The trim piece 91 protrudes further away from the wall than the end surface 22 of the protruding piece 20.

[0054] The trim piece 91 makes surface contact with the protruding portion 42 of the support material 40, particularly the tip surface 43. The trim piece 91 is joined to the tip surface 43 of the protruding portion 42 by adhesive or double-sided adhesive tape.

[0071] Figure 9 is an enlarged view of region IX shown in Figure 8. Similar to case (1), the visible / hidden surface 12A of the strip portion 11A is in contact with the inner surface of the opening 102, i.e., the board 79A, and the frame body 10A is fixed by the fastener 78A. The board 76A protrudes from the inner surface of the opening 102 to the inside of the opening 102, and the side end surface of the board 76 abuts against the back surface 27A of the convex piece portion 21A. The groove 17A is hidden behind the protruding portion of the board 76A. The side end surface of the board 76A may be bonded to the back surface 27 of the convex piece portion 21.

[0072] Figure 10 is an enlarged view of region X shown in Figure 9. Board 75A does not protrude inward from board 79A into the opening 202, and the side end face of board 75A is separated from the back surface 26A of the protruding piece 20A. The side end face of board 75A is in surface contact with the protruding portion 42A of the support material 40A. The side end face of board 75A may be joined to the protruding portion 42A by adhesive or double-sided adhesive tape.

[0073] The visible / hidden surface 12D of the strip portion 11D is in surface contact with the inner surface of the opening 202, that is, the surface of the board 75A. The visible / hidden surface 12D may be bonded to the surface of the board 75A with adhesive or double-sided adhesive tape.

[0074] The protruding portion 21D extends from the side end surface of the board 75A. The protruding portion 21D is separated from the projection 42A, and the back surface 27D of the protruding portion 21D faces the tip surface 43A of the projection 42A.

[0075] The protruding portion 52D of the support material 50D is in surface contact with the inner surface of the opening 202, that is, the surface of the board 75A. The support material 50D is fixed to the board 75 by fasteners 79D.

[0076] The protruding portion 20A extends from the surface of the board 75. The protruding portion 21A is separated from the projection 52D, and the back surface 26A of the protruding portion 20A faces the tip surface 53A of the projection 52A.

[0077] A space is formed enclosed by the convex portion 20A, the protruding portion 42A, the convex portion 21D, and the protruding portion 52D. This space is open to the outside through the gap between the corner formed by the end face 22A and the back surface 26A of the convex portion 20A and the corner formed by the end face 23D and the back surface 27D of the convex portion 21D. The trim piece 900, which is an auxiliary frame material, is housed in this space.

[0078] Figure 11 is a horizontal cross-sectional view of the trim piece 900. The length of the trim piece 900 in the vertical direction corresponds to the length of the frame body 11A and 11D in the vertical direction. For example, the length of the trim piece 900 in the vertical direction is equal to the length of the frame body 11A and 11D in the vertical direction.

[0079] The trim piece 900 has a main body 901, an insertion piece 902, and a protrusion 903. The main body portion 901 is formed to be long in the vertical direction. The cross-sectional shape of the main body portion 901 is rectangular. One corner 912 of the main body portion 901 is chamfered, and in the example shown in Figure 11, this chamfer is a square chamfer. However, this chamfer may also be a rounded chamfer. The corner 913 opposite to corner 912 is also chamfered, and this chamfer is a square chamfer. However, the chamfer of corner 913 may also be a rounded chamfer. The chamfered area of ​​corner 913 is narrower than the chamfered area of ​​corner 912.

[0080] The insertion piece 902 protrudes from corner 914 of the main body 901 in the direction from corner 913 toward corner 914. The direction of protrusion of the insertion piece 902 is perpendicular to the vertical direction. The insertion piece 902 has multiple constrictions so that its thickness is reduced.

[0081] The protrusion 903 projects from corner 915 of the main body 901 in the direction from corner 913 toward corner 915. The projection direction of the protrusion 903 is perpendicular to the vertical direction. The projection direction of the protrusion 903 is perpendicular to the projection direction of the insertion piece 902.

[0082] The protrusion 903 has notches 931 and 932 on both sides of the protrusion 903 at a position close to the main body 901. The notches 931 and 932 are V-shaped notches. When the protrusion 903 is bent laterally, the protrusion 903 is cut at the positions of the notches 931 and 932, and the tip 934 of the protrusion 903 is separated from the remaining protrusion 933, which is the base end of the protrusion 903. The remaining protrusion 933 also protrudes from the corner 915 of the main body 901 in the direction from corner 913 toward corner 915.

[0083] As shown in Figure 10, the main body 901 of the trim piece 900 is contained within the space enclosed by the convex piece 20A, the protruding part 42A, the convex piece 21D, and the protruding part 52D. The main body 901 is in surface contact with the back surface 26A of the convex piece 20A. The main body 901 is in surface contact with the back surface 27D of the convex piece 21D. The corner 913 of the main body 901 protrudes from the space to the outside through the gap between the corner formed by the end face 22A and back surface 26A of the convex piece 20A and the corner formed by the end face 23D and back surface 27D of the convex piece 21D. Therefore, a part of the main body 901 is visible. In other words, a part of the surface from corner 913 to corner 915 is visible from the inside of the opening 102, and a part of the surface from corner 913 to corner 914 is visible from the inside of the opening 202.

[0084] The insert piece 902 of the trim piece 900 is inserted into the gap 58D between the projection 52D and the convex piece 21D. The insert piece 902 is in contact with the projection 52D and the convex piece 21D, and is slightly compressed and deformed by the projection 52D and the convex piece 21D. The compression and deformation of the insert piece 902 prevents the insert piece 902 from coming out of the gap 58D. The convex piece 903 is inserted into the gap 48A between the projection 42A and the convex piece 20A. The convex piece 903 is in contact with the convex piece 20A, but is separated from the projection 42A.

[0085] Alternatively, the trim piece 900 may be inverted, with the insert piece 902 inserted into the gap 48A between the protruding portion 42A and the convex piece portion 20A, and the convex portion 903 inserted into the gap 58D between the protruding portion 52D and the convex piece portion 21D.

[0086] Figure 12 is an enlarged view of region XII shown in Figure 9. The protruding portion 42D of the support material 40D is in surface contact with the inner surface of the opening 202, that is, the surface of the board 75A. The support material 40D is fixed to the board 75 by a fastener 77D. The convex portion 20D is separated from the surface of the board 75A, and the back surface 26D of the convex portion 20D faces the surface of the board 75A. The space between the back surface 26D of the convex portion 20D and the surface of the board 75A houses the trim piece 800, which is an auxiliary frame material. The length of the trim piece 800 in the vertical direction corresponds to the length of the frame body 11D in the vertical direction. For example, the length of the trim piece 800 in the vertical direction is equal to the length of the frame body 11D in the vertical direction.

[0087] The trim piece 800, like the trim piece 900, has a main body 801 and an insert piece 802. The combination of the main body 801 and the insert piece 802 of the trim piece 800 has a shape symmetrical to the combination of the main body 901 and the insert piece 902 of the trim piece 900.

[0088] The trim piece 800 is obtained by cutting off the tip 934 of the protrusion 903 from the trim piece 900 and then inverting it. Therefore, the trim piece 800 has a residual protrusion 833 at the corner 815 of the main body 801 that faces the corner 814 of the main body 801 to which the base end of the insertion piece 802 is connected.

[0089] The main body 801 of the trim piece 900 fits into the space between the back surface 26D of the protruding piece 20D and the surface of the board 75A. The main body 801 is in surface contact with the back surface 26D of the protruding piece 20D. The main body 801 is in contact with the surface of the board 75A. The residual protrusion 833 is either crushed by the board 75A or slightly protruding from the surface of the board 75A. The main body 801 protrudes from the space between the back surface 26D of the protruding piece 20D and the surface of the board 75A, beyond the end face 22D of the protruding piece 20D.

[0090] The insert piece 802 of the trim piece 800 is inserted into the gap 48D between the protruding portion 42D and the convex portion 20D. The insert piece 802 is in contact with the protruding portion 42D and the convex portion 20D, and is slightly compressed and deformed by the protruding portion 42D and the convex portion 20D. This compression and deformation of the insert piece 802 prevents it from coming out of the gap 48D.

[0091] As shown in Figure 8, the frame body 10B is attached to the vertical edge of the opening 102 symmetrically with respect to the frame body 10A with respect to the vertical center plane of the opening 102. The vertical frame members, consisting of the frame body 10E and support members 40E and 50E, are attached to the surface of the board 76B symmetrically with respect to the vertical frame members, consisting of the frame body 10D and support members 40E and 50E, with respect to the vertical center plane of the opening 102. The frame body 10D is used as a trim piece.

[0092] The trim piece 900E is installed in the space enclosed by the protruding parts 21B, 20E of the frame bodies 10B, 10E and the support members 50B, 40E, symmetrically with respect to the trim piece 900 with respect to the vertical central plane of the opening 102. The trim piece 900E has a shape that is symmetrical to the shape of the trim piece 900 with respect to the vertical central plane of the opening 102.

[0093] The trim piece 800E is installed in the space between the protruding piece 21E and the board 76B, symmetrically with respect to the trim piece 800 with respect to the vertical central plane of the opening 102. The trim piece 800E has a shape that is symmetrical to the shape of the trim piece 800 with respect to the vertical central plane of the opening 102.

Summary> (1) Since the convex portion 20 protrudes in the depth direction from the side end of the strip portion 11 beyond the tip end surface 43 of the protruding portion 42, as shown in Figure 4, when the support material 40 is removed from the frame body 10, the convex portion 20 protrudes from the surface of the board 75 and an installation is achieved in which a step is created between the surface of the board 75 and the end surface 22 of the convex portion 20.

[0112] (2) Since the thickness of the protruding piece 20 is thinner than the thickness of the strip portion 11, when the support material 40 is removed from the frame body 10, an eclipse fitting can be achieved in which the protruding piece 20 appears thin, as shown in Figure 4.

[0113] (3) As the insertion piece of the support material 40 is inserted into the groove 16, the bending of the protruding piece 20 is suppressed by the insertion piece 41. As the projection 42 protrudes from the groove 16, bending of the protruding piece 20 occurs until the protruding piece 20 hits the projection 42, but not beyond that. Therefore, the insertion piece 41 and projection 42 of the support material 40 contribute to preventing damage to the protruding piece 20.

[0114] (4) Since the protruding piece 20 protrudes in the depth direction from the side end of the strip portion 11 beyond the tip surface (43) of the projection portion 42, as shown in Figure 5, a mounting space for the trim material 91 is formed on the back of the protruding piece 20. When the trim material 91 is combined with the protruding piece 20, a finish is achieved in which the frame body 10 appears thicker. Similarly, as shown in Figure 9, when the trim material 800 is combined with the protruding piece 20D, a finish is achieved in which the frame body 10D appears thicker. Since the protruding pieces 20 and 20D are supported by the trim material 91 and the trim material 800 respectively, damage to the protruding pieces 20 and 20D is prevented.

[0115] (5) As shown in Figure 10, if the two vertical frame members 11A and 11D are arranged at right angles to each other, a mounting space for the trim piece 900 is formed behind the protruding parts 20A and 21D. When the trim piece 900 is combined with the protruding part 20A, a finish is achieved in which the visible surface of the frame body 10A appears thicker. When the trim piece 900 is combined with the protruding part 21D, a finish is achieved in which the visible surface of the frame body 10D appears thicker.

[0116] (6) As shown in Figure 5, when the strip portion 11 is placed against the mounting surface along the vertical edge of the wall opening 80 and the vertical frame material 1 is attached to the vertical edge of the opening 80, the protruding portion 42 of the support material 40 is also placed against the mounting surface. Thus, the mounting of the support material 40 and the frame body 10 is stabilized.

[0117] (7) Since the gap 48A is formed between the protruding portion 42A and the convex piece portion 20A, the convex portion 903 formed on the trim material 900 can be inserted into the gap 48A. This contributes to the stable installation of the trim material 900.

[0118] (8) As shown in Figure 5, the concealed surface 44 of the protruding portion 42 is flush with the concealed surface 12 of the strip portion 11. Therefore, when the concealed surface 12 is brought into contact with the mounting surface along the vertical edge of the opening 88 in the wall and the vertical frame material 1 is attached to the vertical edge of the opening 80, the concealed surface 44 of the protruding portion 42 is also brought into contact with the mounting surface. Thus, the mounting of the support material 40 and the frame body 10 is stabilized.

[0119] (9) The support material 40 can be easily removed from the frame body 10 by inserting a flathead screwdriver or a thin blade into the recess 46.

[0120] (10) The energy used from the production to the disposal of wood is less than the energy used from the production to the disposal of metal or concrete materials. Therefore, if the frame body 10, support material 40 or support material 50, or two or more of these are made of wood, the vertical frame material 1 contributes to the realization of a decarbonized society by promoting carbon neutrality, which effectively reduces carbon dioxide emissions to zero, and to the achievement of the Sustainable Development Goals (SDGs).
