Description

[Technical field]

[0001] The present disclosure relates to a fitting frame structure, a fitting frame, and a construction method for a fitting frame structure. [Background technology]

[0002] Doors, sliding doors, and other fixtures cover openings in the walls of buildings in an openable and closable manner. Generally, the opening in the wall is rectangular, and three or four sides of the opening are bounded by a fixture frame. The fixture is attached to the fixture frame.

[0003] Patent Document 1 describes a door frame structure (door frame structure). In the door frame structure, the door frame has a horizontal frame and two vertical frames. The horizontal frame frames the top side of the opening, and the two vertical frames frame the left and right sides of the opening, respectively. A door is attached to one of the two vertical frames via a hidden hinge. The concealed hinge comprises two fixed pieces (fixed parts) and a link mechanism that connects them. The vertical frame is made of wood and is columnar. A hinge accommodating hole (accommodating hole) is formed in each of the vertical frame and the door. One of the two fixed pieces of the concealed hinge is accommodated in the hinge accommodating hole of the vertical frame and fixed to the wall, and the other is accommodated in the hinge accommodating hole of the door and fixed to the door.

[0004] Patent Document 2 describes a door frame (fitting frame). The vertical frame of the door frame is an aluminum extrusion molded product having a cylindrical shape. Hinges are fixed to the peripheral wall of the vertical frame and to the hinged door. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2009-97187 A [Patent Document 2] JP 2016-20555 A Summary of the Invention [Problem to be solved by the invention]

[0006] For example, by cutting a wooden (wooden or solid wood) pillar, a vertical frame having hinge receiving holes of appropriate dimensions formed at appropriate positions can be easily obtained. However, wooden vertical frames are prone to warping and distortion, and therefore require skill to construct a door and frame structure with high construction accuracy.

[0007] On the other hand, metal vertical frames are less likely to warp, distort, etc. Therefore, deterioration of construction accuracy caused by warping, distortion, etc. of the vertical frames can be prevented. However, it is not possible to obtain a vertical frame with hinge receiving holes simply by cutting a metal cylinder. For example, it is necessary to provide an opening in the peripheral wall of the cylinder and add a rib around the periphery of the opening to support the fixing part of the hidden hinge.

[0008] In other words, wooden vertical frames have the disadvantage that it is difficult to improve the construction accuracy of the door frame structure, and metal vertical frames have the disadvantage that the manufacturing process is complicated. This problem can also occur in door frames in which, for example, a receiving hole for receiving the fixing part of a pivot hinge or a receiving hole for receiving a lock catch for a door lock is provided in the vertical frame.

[0009] An object of the present disclosure is to provide a door and window frame structure, a door and window frame, and a construction method for a door and window frame structure that has a simple manufacturing process and can improve construction accuracy. [Means for solving the problem]

[0010] The door and window frame structure according to the present disclosure is a door and window frame structure in which a door and window frame borders a rectangular opening provided in a wall body, the door and window frame comprising a vertical frame bordering one side extending in the vertical direction of the opening, the vertical frame comprising a non-metallic columnar member whose length direction is oriented vertically, and a metallic groove-shaped member holding the columnar member inside and fixed to the wall body whose length direction is oriented vertically. The door and window frame structure according to the present disclosure is a door and window frame structure in which a door and window frame borders a rectangular opening provided in a wall, the door and window frame comprising a vertical frame bordering one side extending in the vertical direction of the opening, the vertical frame comprising a non-metallic columnar member with its length oriented vertically, and a metallic grooved member in which the columnar member is held inside and which is fixed to the wall with its length oriented vertically, the side of the columnar member being provided with an accommodation hole for accommodating a specified component, the grooved member being fixed to the wall so that one side panel of the grooved member is in contact with the one side, a window hole being provided in the other side panel of the grooved member, the columnar member being held inside the grooved member so that the window hole and the accommodation hole are in communication with each other. The door frame structure according to the present disclosure is a door frame structure in which a door frame frames a rectangular opening provided in a wall body, the door frame comprising a vertical frame bordering one side extending in the vertical direction of the opening, the vertical frame comprising a non-metallic columnar member with its length oriented vertically, and a metallic channel member that holds the columnar member inside and is fixed to the wall body with its length oriented vertically, the wall body comprising a rectangular columnar vertical member with one side constituting the one side, and a metal channel member that is fixed to the vertical member and has one side facing the wall body. The groove-shaped member has a surface member that forms a wall surface, a contact piece protruding from the long edge of one of the side plates of the groove-shaped member toward the outside of the groove-shaped member, a fixed piece that is flush with the outer surface of the one side plate protruding from the bottom plate of the groove-shaped member on the opposite side of the one side plate, the one side plate and the fixed piece are in contact with the one side surface, and the contact piece is in contact with the other side surface of the vertical member that is connected to the one side surface, and the groove-shaped member is fixed to the wall body by the fixed piece being fixed to the vertical member. The door and window frame structure according to the present disclosure is a door and window frame structure in which a door and window frame borders a rectangular opening provided in a wall, the door and window frame comprising a vertical frame bordering one side extending in the vertical direction of the opening, the vertical frame comprising a non-metallic columnar member with its length oriented vertically, and a metallic grooved member in which the columnar member is held inside and which is oriented vertically and fixed to the wall, the sheet-like or plate-like decorative member decorating the wall surface of the wall and covering the groove opening of the grooved member, and an intervening member fixed to each of the columnar member and the decorative member is interposed between the columnar member and the decorative member.

[0011] In the present disclosure, the door and window frame comprises a vertical frame, which comprises a non-metallic columnar member and a metallic channel member. The vertical frame is constructed by holding the columnar members inside the grooved members. The grooved members are less likely to warp, distort, etc. The columnar members held inside the grooved members are less likely to warp, distort, etc. As a result, the vertical frame is less likely to warp, distort, etc.

[0012] The vertical frame borders one side extending in the vertical direction of a rectangular opening provided in the wall. A channel-shaped member is fixed to the wall. The vertical frame is less likely to warp or distort, which improves the construction accuracy of the door and window frame structure. The pillar-shaped members are easy to process. Therefore, for example, when a specific part needs to be accommodated in the vertical frame, the manufacturing process of the vertical frame is simple because it is only necessary to process the pillar-shaped members for the part accommodation.

[0013] The door and window frame structure of the present disclosure is characterized in that a storage hole for accommodating a specified part is provided on the side of the columnar member, the grooved member is fixed to the wall body so that one side panel of the grooved member contacts the one side, a window hole is provided in the other side panel of the grooved member, and the columnar member is held inside the grooved member so that the window hole and the storage hole are connected to each other on the inside of the grooved member.

[0014] In the present disclosure, the columnar member has an accommodation hole on a side surface thereof. For example, the columnar member can be easily obtained by forming the accommodation hole in a non-metallic column. The channel member is fixed to the wall so that one side plate thereof contacts one side of the opening. The other side plate of the channel member is provided with a window hole. For example, the channel member can be easily obtained by forming a window hole in a metal channel member. The vertical frame can be easily obtained by holding the columnar member inside the channel-shaped member so that the receiving hole and the window hole communicate with each other. From the above, the manufacturing process for the vertical frame is simple.

[0015] A predetermined component is accommodated in the accommodation hole. Since the window hole communicates with the accommodation hole, the component can be accommodated in the accommodation hole through the window hole.

[0016] The door and window frame structure of the present disclosure is characterized in that the accommodating hole penetrates the columnar member, and the part accommodated in the accommodating hole is fixed to the wall body by a fixing member that penetrates the part and the one side panel and is driven into the wall body.

[0017] In the present disclosure, a component is accommodated in an accommodation hole penetrating a columnar member. The accommodated component is fixed to a wall body using a fixing member. The fixing member is driven into the wall body through the component and one side plate of the channel-shaped member. The fixing member can be driven into the wall body through, for example, a window hole in the channel-shaped member.

[0018] The door frame structure according to the present disclosure is characterized in that the part is one fixed part of a hidden hinge, and a hinged door to which the other fixed part of the hidden hinge is fixed covers the opening in an openable and closable manner.

[0019] In the present disclosure, one of the two fixing parts of the concealed hinge is received in the receiving hole of the column-shaped member and fixed to the wall, and the other is fixed to the door. The concealed hinge passes through the window hole of the channel-shaped member. The space between the door attached to the frame via a hidden hinge and the frame is often small. However, as the construction precision of the frame structure has improved, there is no risk of the frame interfering with the opening and closing of the door.

[0020] The door and window frame structure of the present disclosure is characterized in that the wall comprises a rectangular columnar vertical member, one side of which constitutes one of the sides, and a panel member fixed to the vertical member and one side of which constitutes a wall surface of the wall, a contact piece protruding from a long edge of one of the side panels of the channel-shaped member toward the outside of the channel-shaped member, a fixed piece flush with the outer surface of the one side panel protruding from the bottom panel of the channel-shaped member on the opposite side of the one side panel, the one side panel and the fixed piece are in contact with the one side surface, and the contact piece is in contact with the other side surface connected to the one side surface of the vertical member, and the channel-shaped member is fixed to the wall by the fixed piece being fixed to the vertical member.

[0021] In the present disclosure, the wall comprises vertical members and face members. The vertical member is shaped like a rectangular column, and one side of the vertical member forms one side of the opening. The panel is fixed to the vertical members, and one face of the panel forms the wall surface of the wall body.

[0022] A contact piece projects from one side plate of the channel member and a fixing piece projects from the bottom plate of the channel member. The channel member is positioned by one side panel and the fixing piece contacting one side of the vertical member, and the contact piece contacting the other side of the vertical member. This allows the vertical frame to be positioned with high accuracy, further improving the construction accuracy of the door frame structure. After the channel is positioned, the fixing pieces are fastened to the vertical members, thereby fastening the channel to the wall.

[0023] The door and window frame structure according to the present disclosure is characterized in that a sheet-like or plate-like decorative member decorates the wall surface of the wall body and covers the opening of the groove of the groove-shaped member.

[0024] In the present disclosure, a sheet-like or plate-like decorative member decorates the wall surface of the wall body. This decorative member covers the opening of the groove of the channel-shaped member. The decorative member conceals the boundary between the wall body and the vertical frame and the column-shaped member located inside the channel member, thereby improving the aesthetic appearance of the door and window frame structure. Since the decorative member conceals a portion of the vertical frame, the vertical frame appears to be smaller, which improves the design of the door frame structure.

[0025] The door and window frame structure according to the present disclosure is characterized in that an intervening member is interposed between the columnar member and the decorative member, the intervening member being fixed to each of the columnar member and the decorative member.

[0026] In the present disclosure, an intervening member is interposed between the columnar member and the decorative member. The intervening member is fixed to both the columnar member and the decorative member, so that the decorative member can be indirectly fixed to the columnar member. The intervening member supports the portion of the decorative member that covers the opening of the groove of the groove-shaped member, and can maintain its shape.

[0027] The door and window frame structure according to the present disclosure is characterized in that the channel member is an extrusion molded product.

[0028] In the present disclosure, the channel member is formed using an extrusion molding. Extrusion moldings have high dimensional accuracy, which can further improve the construction accuracy of door and window frame structures.

Wall portion 1a and wall portion 1b are connected to each other such that the left edge of wall portion 1b abuts against the right face of wall portion 1a.

[0037] A rectangular opening 11 is provided in the wall 1. The opening 11 is long in the vertical direction. The wall 1 comprises two vertical members 12, a horizontal member 13, and a number of face members 14. The vertical members 12 and horizontal members 13 are each a wooden prism having a rectangular cross section. These serve as the base material for the wall body 1, and are covered with a surface material 14, as will be described later. The vertical members 12 extend in the vertical direction. The two vertical members 12 are adjacent to each other on the left and right with a suitable distance between them. The left vertical member 12 constitutes the wall portion 1a, and the right vertical member 12 constitutes the wall portion 1b. The horizontal member 13 is bridged between the upper ends of the two vertical members 12. The right side surface of the left vertical member 12 , the left side surface of the right vertical member 12 , and the lower surface of the horizontal member 13 form the left edge, right edge, and upper edge of the opening 11 .

[0038] The opening 11 is bordered by a door frame 3. The door frame 3 has two vertical frames 4. Of the two vertical frames 4, one borders the left side of the opening 11, and the other borders the right side of the opening 11. The fitting frame 3 further includes a horizontal frame 31. The horizontal frame 31 is bridged across the upper ends of the two vertical frames 4, and frames the upper side of the opening 11. The configuration of the horizontal frame 31 is not limited.

FIG. 4 is a perspective view of the right-side vertical frame 4 as viewed from the left. FIG. 5 is a perspective view of the right-hand vertical frame 4 as viewed from the right. As shown in FIGS. 2 to 5, the vertical frame 4 includes a column-shaped member 41.

[0040] The columnar member 41 is made of a square timber having a rectangular cross section. The columnar member 41 is made of a non-metal material, for example, wood. The columnar member 41 is used with its length oriented vertically. The columnar member 41 is provided with a rectangular receiving hole 411 . The accommodating hole 411 penetrates the columnar member 41 across both the left and right side surfaces of the columnar member 41. The accommodating hole 411 also opens to the front side surface of the columnar member 41. Although not shown, three accommodating holes 411 are provided at an appropriate distance from each other in the vertical direction.

[0041] The vertical frame 4 further comprises a channel member 5 . The channel 5 is made of metal, for example aluminum, and includes a bottom plate 50 and side plates 51 and 52. The bottom plate 50 and the side plates 51, 52 are each strip-shaped. A side plate 51 (another side plate) protrudes from one long edge of the bottom plate 50. A side plate 52 (one side plate) protrudes from the other long edge of the bottom plate 50 in the same direction as the side plate 51. Each of the side plates 51, 52 extends over the entire length of the bottom plate 50. The protruding length of the side plate 51 from the bottom plate 50 is greater than the protruding length of the side plate 52 from the bottom plate 50.

[0042] The channel member 5 is used with its length oriented vertically, and with the side plates 51 and 52 each protruding forward from the bottom plate 50. The side plate 51 is located on the left side, and the side plate 52 is located on the right side. The opening of the channel of the channel member 5 (the space between the front edges of the side plates 51 and 52) faces forward.

[0043] The side plate 51 is provided with a screen 53. The screen 53 has a shape such that the tip of the side plate 51 protruding from the bottom plate 50 is bent toward the inside of the channel-shaped member 5 into a U-shape in a plan view. The screen 53 extends over the entire length of the side plate 51. The side plate 51 is provided with a rectangular window hole 511. The position of the window hole 511 corresponds to the position of the accommodation hole 411 in the columnar member 41. The front edge of the window hole 511 is located near the boundary between the side plate 51 and the screen 53.

[0044] A contact piece 54 is provided on the side plate 52. The contact piece 54 is a thin piece perpendicular to the outer surface of the side plate 52, and protrudes from the tip of the side plate 52 in the direction of protrusion from the bottom plate 50 toward the outside of the channel member 5. The contact piece 54 extends over the entire length of the side plate 52. A rectangular through hole 521 is provided in the side plate 52. The through hole 521 is located opposite the window hole 511 of the side plate 51. The front edge of the through hole 521 is located near the boundary between the side plate 52 and the contact piece .

[0045] The bottom plate 50 is provided with a fixing piece 55. The fixing piece 55 protrudes rearward from the bottom plate 50 such that one surface of the fixing piece 55 is flush with the outer surface of the side plate 52. The fixing piece 55 extends over the entire length of the bottom plate 50. The fixing piece 55 is provided with a through hole 551. Although not shown, a plurality of through holes 551 are provided at appropriate intervals from each other in the vertical direction.

[0046] The channel member 5 is provided with two holding pieces 561 and 562 . The retaining piece 561 protrudes leftward from the tip of the fixed piece 55 in the direction in which it protrudes from the bottom plate 50. The retaining piece 561 spans the entire length of the fixed piece 55. Similarly, the retaining piece 562 protrudes leftward from the base end of the side plate 51 in the direction in which it protrudes from the bottom plate 50. The retaining piece 562 spans the entire length of the side plate 51. The left-right positions of the tips of the retaining pieces 561, 562 are the same.

[0047] A reinforcing piece 57 perpendicular to the holding pieces 561 and 562 is provided between the holding pieces 561 and 562. The reinforcing piece 57 is provided with an insertion hole 571. The insertion hole 571 is located at a position facing the through hole 551 of the fixing piece 55.

[0048] The channel member 5 is fixed to the vertical member 12 such that the side plate 52 and the fixing piece 55 contact the left side surface of the vertical member 12 and the contact piece 54 contacts the front side surface of the vertical member 12. The channel member 5 is fixed to the vertical member 12 by fastening the fixing piece 55 to the vertical member 12 with a screw. When fastening the fixing piece 55 with a screw, a tool for fastening the screw (e.g., an impact driver) is inserted into the insertion hole 571. Also, a screw 61 is inserted into the through hole 551 of the fixing piece 55.

[0049] After the fixing piece 55 is fastened with the screws, the concealing member 42 is attached to the holding pieces 561 and 562. The concealing member 42 is strip-shaped. The length of the concealing member 42 is the same as that of the channel-shaped member 5. Both edges in the width direction of the concealing member 42 engage with the tips of the holding pieces 561, 562, respectively, so that the concealing member 42 is held by the holding pieces 561, 562. Since the concealing member 42 conceals the screws 61, the aesthetic appearance of the door and window frame structure is improved.

[0050] The columnar member 41 is held inside the groove member 5 so that the accommodation hole 411 of the columnar member 41 communicates with the window hole 511 and the through hole 521 of the groove member 5. The bottom plate 50 of the groove member 5 contacts the rear side surface of the columnar member 41, and the side plates 51 and 52 of the groove member 5 contact both the left and right side surfaces of the columnar member 41. The screen 53 covers one side portion of the front side surface of the columnar member 41 and contacts the front side surface of the columnar member 41. Due to friction between the channel member 5 and the columnar member 41, the columnar member 41 is held inside the channel member 5. There is no risk of the columnar member 41 inside the channel member 5 passing through the opening of the groove of the channel member 5 and detaching to the outside of the channel member 5.

[0051] An intervening member 43 is attached to the front side surface of the columnar member 41 over the entire length of the columnar member 41. The intervening member 43 is a long and narrow rectangular plate, and covers the portion of the front side surface of the columnar member 41 that is not covered by the blind 53. The intervening member 43 is made of a non-metallic material, and it is desirable that the intervening member 43 be made of the same material as the columnar member 41. The columnar member 41 is concealed from the left side by the side plate 51, and the intermediate member 43 is concealed from the left side by the concealment screen 53. This improves the aesthetic appearance of the door and window frame structure. The means for fixing the interposed member 43 to the columnar member 41 is not limited to pasting. For example, the interposed member 43 may be fixed to the columnar member 41 by screws.

[0052] As shown in Figures 1 and 2, an opening 11 bordered by a door frame 3 is covered by a door 7 so as to be able to be opened and closed. The door 7 is in the shape of a rectangular plate, and a lever-shaped handle 71 is provided in the center of the left side. The handles 71 are provided on both sides of the door 7. The handles 71 can swing around a shaft 711 that is perpendicular to the door 7.

[0053] 1, three hidden hinges 62 are arranged vertically on the right side of the door 7. The door 7 is attached to the vertical frame 4 via the three hidden hinges 62.

[0054] 2 and 3, the hidden hinge 62 includes two fixing portions 621. The two fixing portions 621 are detachably connected to each other via a link mechanism 622. Of the two fixing portions 621 of the hidden hinge 62, one (a specified part) is accommodated in the accommodation hole 411 of the columnar member 41. The fixing portion 621 accommodated in the accommodation hole 411 is fixed to the vertical member 12 by a screw 61 (fixing member). The screw 61 penetrates a through hole (not shown) provided in the fixing portion 621 and the through hole 521 of the groove-shaped member 5. Although not shown, a plurality of screws 61 spaced apart from each other in the vertical direction fix the fixing portion 621 to the vertical member 12.

[0055] A rectangular accommodating hole 72 is provided on the right end surface of the door 7. The other of the two fixing parts 621 is accommodated in the accommodating hole 72 of the door 7. The fixing part 621 accommodated in the accommodating hole 72 is fixed to the door 7 with a screw. Although not shown, three accommodating holes 72 are provided vertically spaced apart from one another on the right end surface of the door 7. The positions of the accommodating holes 72 correspond to the positions of the accommodating holes 411 in the columnar member 41. The right end surface of the door 7 is decorated with a strip-shaped decorative member 73. The decorative member 73 has an opening corresponding to the accommodation hole 72. The hidden hinge 62 passes through the window hole 511 of the channel member 5 and the opening of the decorative member 73.

[0056] The door 7 is attached to the vertical member 12 via a hidden hinge 62 so that the door 7 can open up to 180° from the front to the right side. When the door 7 is closed, the right end face of the door 7 and the side panel 51 of the groove member 5 face each other on the left and right with a small gap between them. It is difficult to see the hidden hinge 62 through this gap. In other words, when the door 7 is closed, the hidden hinge 62 is hidden by the door 7 and the vertical frame 4. This improves the aesthetic appearance of the door frame structure.

[0057] When the door 7 is closed, the rear surface of the door 7 and the front surface of the holding piece 562 of the groove-shaped member 5 face each other in the front-rear direction. The shielding member 44 is attached to the front surface of the holding piece 562. The shielding member 44 is so-called mohair, and comprises a band-like base and a large number of hairs planted on one surface of the base. The holding piece 562 holds the base of the shielding member 44 such that the hairs of the shielding member 44 protrude forward. The shielding member 44 blocks drafts and light leaks by closing the gap that occurs between the door 7 and the vertical frame 4 when the door 7 is closed.

[0058] 2 and 3, the front half of the left side surface of the vertical member 12 is covered by the vertical frame 4. The rear half of the left side surface of the vertical member 12 is covered by the panel member 14 with a splint 15 interposed therebetween. The face material 14 is, for example, a gypsum board. The splint 15 may be a square piece of timber that spans the entire length of the vertical member 12, or may be a plurality of square pieces of timber arranged vertically. For example, a scrap piece of wood is used as the splint 15. The splint 15 is fixed to the vertical member 12 with a screw. The panel 14 covering the left side of the vertical member 12 covers the splint 15 from the left side and is fixed to the splint 15 with screws. This panel 14 is adjacent to the rear side of the vertical frame 4. The front end face of this panel 14 abuts against the rear face of the retaining piece 561 of the channel-shaped member 5.

[0059] Since the panel 14 conceals the rear half of the left side of the vertical member 12 (the portion not covered by the vertical frame 4), the vertical frame 4 can be used in other wall bodies 1 in which the vertical member 12 has a different length in the front-to-rear direction. Because the splint 15 is interposed between the vertical member 12 and the face member 14, when the door frame structure is viewed from the rear, the area in which the channel member 5 is exposed is smaller in the left-right direction. As a result, the width of the vertical frame 4 appears narrower, improving the design of the door frame structure.

[0060] The rear side of the vertical member 12 is covered with a panel 14 . The panel 14 covering the rear side surface of the vertical member 12 extends in all directions, covers the splint 15 from the rear side, and is fixed to the vertical member 12 and the splint 15 with screws. The outer surface of this panel 14 forms the rear surface of the wall portion 1b of the wall body 1. In addition, this panel 14 conceals the rear end surface of the panel 14 covering the left side surface of the vertical member 12 from the rear side. The outer surfaces of the two panel members 14 covering the left side and rear side of the vertical member 12 are finished in a common pattern.

[0061] The front side of the vertical member 12 is covered with a face member 14 . The panel 14 covering the front side of the vertical member 12 extends vertically and horizontally, and is fixed to the vertical member 12 with screws. The outer surface of this panel 14 forms the front surface of the wall portion 1b of the wall body 1, and the left end surface of the panel 14 abuts against the right side surface of the columnar member 41 and the right end surface of the intervening member 43. This panel 14 covers the contact piece 54 of the channel member 5. Therefore, strictly speaking, a gap is generated between the panel 14 and the vertical member 12. However, since the contact piece 54 is sufficiently thin, there is no risk that the gap between the panel 14 and the vertical member 12 will deteriorate the construction accuracy. The panel 14 covering the front side (and rear side) of the vertical member 12 also covers the front side (and rear side) of the horizontal member 13 and is fixed to the horizontal member 13 (see FIG. 1).

[0062] The thickness of the aforementioned intervening member 43 is set so that the front surface of the intervening member 43 fixed to the front side surface of the columnar member 41 is flush with the outer surface of the face member 14 covering the front side surface of the vertical member 12. A decorative member 64 is affixed to the outer surface of this face member 14 and the front surface of the intervening member 43. The decorative member 64 is, for example, a decorative sheet made of synthetic resin. The decorative member 64 decorates the face member 14 and covers the opening of the groove of the channel-shaped member 5. The intervening member 43 supports the portion of the decorative member 64 that covers the opening of the groove of the channel-shaped member 5 and can maintain its shape.

[0063] The decorative member 64 conceals the boundary between the wall body 1 and the vertical frame 4, and the column member 41 inside the channel member 5, thereby improving the aesthetic appearance of the fitting frame structure. Since a portion of the vertical frame 4 is concealed by the decorative member 64, only the concealment 53 of the channel member 5 is exposed when the door frame structure is viewed from the front. As a result, the width of the vertical frame 4 appears narrow, improving the design of the door frame structure.

[0064] 1 and 3, a baseboard 65 is attached to the lower edge of the front surface of the wall portion 1a. The baseboard 65 is a long, narrow plate with its longitudinal direction facing left and right. The left end of the baseboard 65 abuts against the right surface of the screen 53 of the channel member 5. The screen 53 hides the decorative member 64 and the baseboard 65 from the left side, thus improving the aesthetic appearance of the door and window frame structure.

[0065] Next, the left side vertical frame 4 and the left side vertical member 12 will be described. FIG. 6 is an enlarged cross-sectional view of the left vertical frame 4 and its vicinity in the door / window frame structure. As described above, the configuration of the right-side vertical frame 4 and the configuration of the left-side vertical frame 4 are generally symmetrical to each other. In the left-side vertical frame 4, the channel member 5 is also used such that its length faces up and down and each of the side plates 51, 52 protrudes forward from the bottom plate 50. However, the side plate 51 is located on the right side and the side plate 52 is located on the left side. The channel member 5 is fixed to the vertical member 12 such that the side plate 52 and the fixing piece 55 contact the right side surface of the vertical member 12 and the contact piece 54 contacts the front side surface of the vertical member 12.

[0066] The columnar member 41 has one accommodating hole 411. The inter-channel member 5 has one window hole 511 and one through hole 521. The columnar member 41 is held inside the inter-channel member 5 such that the accommodating hole 411, the window hole 511, and the through hole 521 are in communication with each other.

[0067] The accommodating hole 411 is provided on the right peripheral surface of the columnar member 41. This accommodating hole 411 does not penetrate the columnar member 41 and does not open to the front peripheral surface of the columnar member 41. A latch receiver 63 (a specified part) is accommodated in the accommodation hole 411. The latch receiver 63 is box-shaped with one open side, and is accommodated in the accommodation hole 411 with the open side facing rightward. A flange is provided on the periphery of the open side of the latch receiver 63, and a recess into which this flange is fitted is provided on the periphery of the window hole 511 of the side plate 51. The latch receiver 63 is fixed to the vertical member 12 with screws (not shown) that pass through the latch receiver 63, the bottom of the accommodation hole 411, and the through-hole 521 of the side plate 52 and are driven into the vertical member 12.

[0068] The latch receiver 63 is not limited to being screwed to the vertical member 12. For example, the flange of the latch receiver 63 may be screwed to the columnar member 41 by a screw penetrating the flange and the side plate 51. In this case, the through hole 521 of the channel member 5 may be omitted.

[0069] A receiving hole 72 is also provided on the left end surface of the door 7. A latch member 66 is received in this receiving hole 72. The latch member 66 is fixed to the door 7 with a screw (screw not shown). A latch 661 appears and disappears from the latch member 66 in conjunction with the swinging of the handle 71. When the door 7 is closed, the latch 661 that has advanced from the latch member 66 is received by the latch receiver 63. As a result, the door 7 is prevented from opening. When the latch 661 retracts from the latch receiver 63 and retracts into the latch member 66, the door 7 can be opened. The left end surface of the door 7 is also decorated with a decorative member 73 .

[0070] The vertical frame 4 covers the front half of the right side of the vertical member 12. The rear half of the right side of the vertical member 12 is covered by the panel member 14. The panel 14 covering the right side of the vertical member 12 extends vertically and front-to-back and is fixed to the vertical member 12 with screws. The outer surface of this panel 14 forms the right side of the wall portion 1a of the wall body 1 and is decoratively finished. This panel 14 is adjacent to the rear side of the vertical frame 4. The front end surface of this panel 14 abuts against the rear surface of the retaining piece 561 of the channel member 5.

[0071] A splint 16 is affixed to the intermediate member 43 of the vertical frame 4. The splint 16 is, for example, a square timber that spans the entire length of the intermediate member 43. Like the splint 15, the splint 16 is made from scrap wood. The splint 16 is concealed from the right side by the screen 53 of the channel member 5. This improves the aesthetic appearance of the door and window frame structure.

[0072] A stud 17 rises from the floor 2 (see FIG. 1) adjacent to the front side of the vertical member 12. A contact piece 54 of the channel member 5 is interposed between the vertical member 12 and the stud 17. The rear half of the right side of the stud 17 is covered by the vertical frame 4 and the splint 16.

[0073] The front half of the right side of the partition wall 17 is covered with the panel 14 . The panel 14 covering the right side of the partition 17 extends vertically and front-to-back and is fixed to the partition 17 with screws. The outer surface of this panel 14 forms the right side of the wall portion 1a of the wall body 1 and is decorative. This panel 14 is located in front of the vertical frame 4. The rear end face of this panel 14 abuts against the splint 16. The right edge of the front side face of the splint 16 is exposed and is decorated in the same way as the panel 14 (for example, by attaching a decorative sheet).

[0074] Regardless of whether the vertical frame 4 is on the left or right side, the columnar members 41 can be easily obtained by forming the accommodation holes 411 in wooden square timber. The channel member 5 is an extrusion molded product integrally having a bottom plate 50, side plates 51, 52, a screen 53, a contact piece 54, a fixing piece 55, holding pieces 561, 562, and a reinforcing piece 57. The window hole 511, the through holes 521, 551, and the insertion opening 571 are formed after extrusion molding.

[0075] The columnar member 41 and the channel member 5 are manufactured, for example, in a factory, and are shipped in a state in which the columnar member 41 is held inside the channel member 5 so that the receiving hole 411 and the window hole 511 communicate with each other. The columnar member 41 is inserted into the channel member 5 from the opening at the end of the channel member 5 in the longitudinal direction. For the above reasons, the manufacturing process for the vertical frame 4 is simple. In addition, the column members 41 may be inserted inside the channel members 5 at the construction site of the door and window frame structure.

[0076] The construction of the door and window frame structure of this embodiment is carried out simultaneously with the construction of the wall body 1. 7 to 9 are cross-sectional views for explaining a construction method for the door and window frame structure. As shown in FIG. 7, only the vertical members 12 of the wall body 1 are set upright on the floor 2 (see FIG. 1) in advance. The worker prepares two vertical frames 4.

[0077] One of the two vertical frames 4 has three storage holes 411 and window holes 511. The worker turns the vertical frame 4 up and down and aligns it with the right-side vertical member 12. The worker positions it in the left-right direction by bringing the side panel 52 and fixing piece 55 of the channel member 5 into contact with the left side surface of the vertical member 12. The worker also positions it in the front-to-back direction by bringing the contact piece 54 of the channel member 5 into contact with the front side surface of the vertical member 12. The worker positions it in the up-down direction by bringing the lower end of the channel member 5 into contact with the floor 2. After positioning the vertical frame 4, the worker fixes the vertical frame 4 to the vertical member 12 by screwing the fixing piece 55 to the vertical member 12.

[0078] The other of the two vertical frames 4 is provided with one accommodation hole 411 and one window hole 511. The worker turns this vertical frame 4 up and down and aligns it along the left vertical member 12. Except for bringing the side panel 52 and fixing piece 55 of the channel member 5 into contact with the right side surface of the vertical member 12, the worker fixes the vertical frame 4 to the vertical member 12 in the same manner as for the right vertical frame 4. The worker may attach the intervening member 43 to the columnar member 41 before fixing the vertical frame 4 to the vertical member 12, or may attach the intervening member 43 to the columnar member 41 after fixing the vertical frame 4 to the vertical member 12.

[0079] As shown in FIG. 8, the worker fastens the splint 15 to the left side surface of the right-side vertical member 12 with a screw. The worker attaches the splint 16 to the intermediate member 43 of the left vertical frame 4. The worker sets up the partition 17 on the floor 2. The partition 17 may be fixed to the vertical member 12 on the left side.

[0080] As shown in Fig. 9, the worker covers the front side surface of the right-side vertical member 12 with a panel 14 and screws this panel 14 to the vertical member 12. After that, the worker attaches a decorative member 64 (see Fig. 3) to the outer surface of this panel 14 and the front surface of the intervening member 43.

[0081] The worker covers the left side surface of the right vertical member 12 with the panel 14 via the splint 15, and fastens this panel 14 to the splint 15 with screws. The worker covers the rear side surface of the right vertical member 12 and the rear side surface of the splint 15 with the panel 14, and fastens this panel 14 to the splint 15 and the vertical member 12 with screws. The worker covers the right side surface of the left vertical member 12 with a panel 14 and fastens this panel 14 to the vertical member 12 with a screw. The worker covers the right side surface of the partition 17 with a panel 14 and fastens this panel 14 to the partition 17 with a screw.

[0082] Although not shown in the figure, a worker spans the horizontal frame 31 across the two vertical frames 4 on the left and right. For the right-side vertical frame 4, the worker accommodates the fixing portion 621 of the hidden hinge 62 in the accommodation hole 411 of the columnar member 41 through the window hole 511 of the channel-shaped member 5. Next, the worker drives the screw 61 into the vertical member 12 so that it passes through the fixing portion 621 and the through-hole 521 of the channel-shaped member 5, thereby screwing the fixing portion 621 to the vertical member 12. The screw 61 can be driven into the wall body 1 through the window hole 511 of the channel-shaped member 5.

[0083] For the left vertical frame 4, the worker inserts the latch receiver 63 into the receiving hole 411 of the columnar member 41 through the window hole 511 of the channel member 5. Next, the worker drives a screw (not shown) into the vertical member 12 so that it penetrates the fixing portion 621 and the through hole 521 of the channel member 5, thereby screwing the latch receiver 63 to the vertical member 12.

[0084] As shown in FIG. 3, the worker attaches the door 7 to the vertical frame 4 by connecting the fixing part 621 fixed to the door 7 with a screw to the fixing part 621 fixed to the vertical member 12 with a screw via a link mechanism 622. The worker also attaches the cover members 42 and the shielding members 44 to each of the channel members 5 . Furthermore, the worker attaches a baseboard 65 to the lower edge of the wall portion 1a.

[0085] According to the above-described door and window frame structure, the channel member 5, which is a metal extrusion molding, has high dimensional accuracy and is less prone to warping, distortion, etc. The columnar members 41 held inside the channel member 5 are less prone to warping, distortion, etc. As a result, the vertical frame 4 is less prone to warping, distortion, etc. In addition, the side plate 52 and the fixing piece 55 contact one side of the vertical member 12, and the contact piece 54 contacts the other side of the vertical member 12, thereby positioning the channel member 5. Therefore, the vertical frame 4 can be positioned with high precision. As a result of the above, the construction accuracy of the door and window frame structure can be improved.

[0086] The pillar-shaped members 41 and the channel-shaped members 5 can be easily obtained. The vertical frame 4 can be easily obtained by combining the two, so the manufacturing process of the vertical frame 4 is simple. The space between the door 7 attached to the door frame 3 via the hidden hinge 62 and the door frame 3 is often small. However, since the construction accuracy of the door frame structure has improved, there is no risk that the door frame 3 will hinder the opening and closing of the door 7.

[0087] Both of the two vertical members 12 may form the wall portion 1b. In this case, the configuration of the wall 1 around the left vertical member 12 is generally symmetrical to the configuration of the wall 1 around the right vertical member 12. The fitting frame 3 in this embodiment is a three-sided frame, but is not limited to this and may be a four-sided frame. The door 7 may be attached to the door frame 3 via a pivot hinge in which two fixed parts are connected by a rotating shaft, instead of the hidden hinge 62.

[0088] The fixture attached to the fixture frame 3 is not limited to the hinged door 7, and may be, for example, a sliding door. In this case, the receiving hole 411 and the window hole 511 are not provided in the right-side vertical frame 4. A lock may be provided at the door end of the sliding door. In this case, a lock receiver is received in the receiving hole 411 in the left-side vertical frame 4.

[0089] The columnar member 41 may be made of a synthetic resin. The shapes of the accommodating hole 411 of the columnar member 41 and the window hole 511 of the channel member 5 are not limited to rectangular. The accommodating hole 411 and the window hole 511 each have a shape corresponding to the outer shape of the component to be accommodated in the accommodating hole 411. In this embodiment, the window holes 511 and the through holes 521 of the inter-engagement member 5 correspond one-to-one, and a plurality of screws 61 pass through the same through hole 521. However, the through holes 521 of the inter-engagement member 5 may be provided at the positions through which the screws 61 pass, and the number of the through holes 521 may be the same as the number of the screws 61. The fixing member is not limited to the screw 61, but may be, for example, a nail. The decorative member 64 is not limited to a sheet shape, but may be a plate shape.

[0090] Embodiment 2. FIG. 10 is a cross-sectional view of the door and window frame structure according to the second embodiment, showing an enlarged view of the vicinity of the right-hand vertical frame 4. The door frame structure of this embodiment is substantially the same as the door frame structure of embodiment 1, except that the vertical frame 4 does not include the intervening member 43. Below, the differences from embodiment 1 will be explained, and other components that are the same as those in embodiment 1 will be given the same reference numerals and their explanation will be omitted.

[0091] The panel material 14 covering the front side surface of the vertical member 12 is thinner than the panel material 14 covering the front side surface of the vertical member 12 in embodiment 1. The front surface of the panel material 14 is disposed flush with the front side surface of the columnar member 41. The decorative member 64 in this embodiment is attached to the outer surface of the face material 14 and the front side surface of the columnar member 41. The decorative member 64 is, for example, a ceramic decorative plate. In this embodiment as well, the decorative member 64 decorates the face material 14 and covers the opening of the groove of the groove-shaped member 5.

[0092] The decorative member 64 is not limited to a plate shape, but may be a sheet shape. If the decorative member 64 has good shape retention, the decorative member 64 does not need to be attached to the front side surface of the columnar member 41.

[0093] In this embodiment, the vertical frame 4 does not include an intervening member 43. However, it is preferable that the vertical frame 4 in which the columnar member 41 is inserted inside the channel member 5 and the intervening member 43 that is not yet fixed to the columnar member 41 are sold as a set, and whether or not to use the intervening member 43 is determined at the construction site of the door and window frame structure. When using a sheet-like decorative member 64 and a thick face material 14 as in the first embodiment, the worker forms a vertical frame 4 with an intervening member 43 as shown in Fig. 3. When using a plate-like decorative member 64 and a thin face material 14 as in the present embodiment, the worker forms a vertical frame 4 without an intervening member 43 as shown in Fig. 10. Any unused intervening member 43 may be reused as a splint for reinforcing other members or filling gaps between other members, a batten for protecting other members being processed, etc.

[0094] Embodiment 3. FIG. 11 is a cross-sectional view of the door / window frame structure according to the third embodiment, showing an enlarged view of the area near the right-hand vertical frame 4. The door frame structure of this embodiment is substantially the same as the door frame structure of embodiment 1, except that an end part 67, which will be described later, is disposed between the screen 53 and the baseboard 65. Below, the differences from embodiment 1 will be explained, and other components that are the same as those in embodiment 1 will be given the same reference numerals and their explanation will be omitted.

[0095] If the front end of the screen 53 is located behind the front-to-rear position of the front surface of the baseboard 65, the screen 53 cannot cover the left end surface of the baseboard 65. Therefore, an end part 67 is provided between the screen 53 and the baseboard 65.

[0096] FIG. 12 is a perspective view for explaining the attachment of the end part 67. As shown in FIG. 11 and 12, the end part 67 has a rectangular plate shape and is used with one surface facing forward. The end part 67 has a tapered shape that becomes thinner from the right side to the left side. The thickness of the right portion of the end part 67 is the same as the thickness of the baseboard 65. The thickness of the left portion of the end part 67 is the same as the length in the front-rear direction from the front surface of the intervening member 43 to the front end of the screen 53.

[0097] The end part 67 is provided with an engagement protrusion 671 and a fixing piece 672. The engagement protrusion 671 protrudes leftward from the left end surface of the end part 67. The fixing piece 672 protrudes rightward from the right end surface of the end part 67. An engagement recess 531 is provided on the right surface of the blind 53. The engagement recess 531 is a groove extending vertically, and is provided during extrusion molding of the interdigital member 5. The engagement protrusion 671 of the end part 67 is inserted into the engagement recess 531 of the blind 53, and engages with the inner surface of the engagement recess 531.

[0098] The base board 65 comprises a base member 651 and a cover member 652 . The base member 651 is strip-shaped and is arranged along the lower edge of the front surface of the wall body 1, and is fixed to the face material 14 covered with the decorative member 64 by tacker fasteners. The fixing piece 672 of the end part 67 is adjacent to the left end of the base member 651, and is fixed to the face material 14 together with the base member 651 by tucker fastening. The staple 68 for tucker fastening is U-shaped, and is driven in so as to straddle the fixing piece 672 and the base member 651.

[0099] The cover member 652 of the baseboard 65 is belt-shaped and attached to the base member 651 so as to cover the base member 651 and the fixing piece 672 of the end part 67 from above and the front. The cover member 652 conceals the base member 651 and the fixing piece 672. When attaching the end part 67, the worker inserts the engaging protrusion 671 into the engaging recess 531 of the screen 53, and then tacks the fixing piece 672 together with the base member 651 to the face material 14.
