[Modes for carrying out the invention]

[0010] A preferred embodiment of the joinery according to the present invention will be described in detail below with reference to the attached drawings. For convenience, the terms "depth direction" and "face direction" may be used in the following description. The depth direction is the direction along the depth of the joinery, as indicated by arrow A in the figure. The surface along the depth direction may be referred to as the depth surface. The "visible direction" refers to the direction perpendicular to the depth direction and running vertically, in the case of elements that extend horizontally, such as bottom frames. In the case of elements that extend vertically, such as vertical frames, the visible direction refers to the direction perpendicular to the depth direction and running horizontally. The surface that aligns with the visible direction is sometimes called the visible surface.

[0011] (Embodiment 1) Figures 1 and 2 show a joinery piece to which a frame profile, which is Embodiment 1 of the present invention, is applied. The joinery piece illustrated here is called a stepped window, having an upper vertical sliding window and a lower fixed window inside a single frame 10. The frame 10 is composed of an outer perimeter frame 10a formed by assembling an upper frame (horizontal frame) 11, a lower frame (horizontal frame) 12, and left and right vertical frames 13 around the perimeter, and a transom (internal frame material) 14 provided to divide the internal space of the outer perimeter frame 10a into two vertical sections. In this frame 10, a sash 20 constituting a vertical sliding window is arranged in the portion enclosed by the upper frame 11, transom 14, and left and right vertical frames 13 so as to be openable to the outside, and a panel 30 such as double-glazed glass constituting a fixed window is arranged in the portion enclosed by the transom 14, lower frame 12, and left and right vertical frames 13. The upper frame 11, lower frame 12, left and right vertical frames 13, and transom 14 that constitute the frame body 10 are each composed of a metal frame part formed from a metal such as an aluminum alloy and a resin frame part formed from resin. The shoji screen 20 is constructed by assembling an upper frame 22, a lower frame 23, and left and right vertical frames 24 around the four sides of a rectangular panel 21 such as a double-glazed glass panel. The upper frame 22, lower frame 23, and left and right vertical frames 24 that constitute the shoji screen 20 are each composed of an exterior metal frame part 25A formed from a metal such as an aluminum alloy and an interior resin frame part 25B formed from resin. The following will mainly describe the structure of the transom 14 and also explain the characteristic features of the present invention.

[0012] As shown in Figures 2 to 5, the metal frame portion 40 of the transom 14 is integrally molded from a metal body 40a, a door stop wall portion 40b, an upper resin frame insertion portion 40c, an outer panel support portion 40d, an inner panel support portion 40e, and a lower resin frame insertion portion 40f. The metal body 40a has an irregular shape with a hollow form in which the exterior-facing surface 40a1 and the interior-facing surface 40a2 extend almost vertically. The door stop wall portion 40b extends upward from the upper surface of the metal body 40a, closer to the interior side. A sealing member S1 is attached to the upper edge of the door stop wall portion 40b that faces the exterior. An upper cover groove portion 40g that opens upward is provided on the upper edge of the door stop wall portion 40b that faces the interior. The upper resin frame insertion portion 40c is provided on the upper surface of the metal body 40a at the indoor-facing edge and opens upward. The outer panel support portion 40d extends downward from the outer edge on the lower surface of the metal body 40a. The inner panel support portion 40e extends downward from a position on the lower surface of the metal body 40a that is on the indoor side of the outer panel support portion 40d. These outer panel support portions 40d and inner panel support portions 40e are provided facing each other with a gap between them that is larger than the thickness of the panel 30. The extended edge of the outer panel support portion 40d is provided with an outer pocket portion 40h that protrudes from the portion facing the room. The extended edge of the inner panel support portion 40e is provided with an inner pocket portion 40i on the portion facing the room, and further down is provided with an upper cover groove portion 40j that opens to the room. The lower resin frame insertion section 40f is a groove-shaped section provided on the inner edge of the lower surface of the metal body 40a, and is formed to open downwards.

[0013] The resin frame portion 41 of the transom 14 is composed of three parts: an upper frame component 42 provided on the indoor side of the upper part of the metal frame portion 40, a lower frame component 43 provided on the indoor side of the lower part of the metal frame portion 40, and a cover frame component (cover member) 44 provided between the upper frame component 42 and the lower frame component 43. The upper frame component 42, the lower frame component 43, and the cover frame component 44 are each configured to have approximately the same longitudinal dimensions as the metal frame portion 40.

[0014] The upper frame component 42 is formed by integrally molding an upper resin frame body 42a, upper insertion fin portions 42b, and upper cover mounting pieces 42c. The upper resin frame body 42a extends substantially horizontally along the prospective direction. In the illustrated example, the upper resin frame body 42a is configured to have a length corresponding to the dimension from the doorstop wall portion 40b to the upper resin frame insertion portion 40c on the upper surface of the metal frame portion 40. On the lower surface of the upper resin frame body 42a at the outdoor side portion, an upper cover protrusion 42d is provided downward. The upper insertion fin portions 42b extend substantially vertically downward from the edge portion located on the indoor side of the upper resin frame body 42a. The upper cover mounting pieces 42c extend obliquely downward toward the indoor side from the edge portion located on the indoor side of the upper resin frame body 42a. Although not clearly shown in the figure, the upper cover mounting pieces 42c can be elastically deformed via the base end portions. When the upper cover mounting pieces 42c are deformed upward, the protruding end portions can be arranged above the upper resin frame body 42a. On the protruding end portions of the upper cover mounting pieces 42c, upper contact ribs 42e are provided to protrude downward.

[0015] The upper frame component 42 having the above-described configuration is mounted on the metal frame portion 40 by inserting the upper cover protrusion 42d into the upper cover groove portion 40g and inserting the upper insertion fin portions 42b into the upper resin frame insertion portion 40c. As is clear from the figure, in the metal frame portion 40 with the upper frame component 42 mounted, the upper edge surface of the doorstop wall portion 40b and the upper surface of the portion located more indoors than this are covered by the upper frame component 42. The upper cover mounting pieces 42c protrude to the indoor side more than the upper resin frame insertion portion 40c.

[0016] The lower frame component 43 has a lower resin frame body 43a, an outer cover piece portion 43b, an inner insertion fin portion 43c, and a lower cover mounting piece 43d. The lower resin frame body 43a has a hollow shape with a substantially rectangular cross-section. The outer cover piece portion 43b extends outward from the edge portion on the outdoor side and below of the lower resin frame body 43a, then bends upward, and further bends inward. The inner insertion fin portion 43c is inserted into the lower resin frame insertion portion 40f of the metal frame portion 40, and extends upward from the edge portion on the indoor side and above of the lower resin frame body 43a. The lower cover mounting piece 43d is provided indoors from the portion on the indoor side and above of the lower resin frame body 43a and extends obliquely upward gradually. Although not shown in the figure, this lower cover mounting piece 43d can be elastically deformed via the base end portion. When the lower cover mounting piece 43d is deformed downward, the protruding end portion can be arranged below the horizontal position. A lower contact rib 43e is provided at the protruding end portion of the lower cover mounting piece 43d so as to protrude upward. In the first embodiment, the lower cover mounting piece 43d and the lower contact rib 43e are configured to have a symmetrical shape with respect to the upper cover mounting piece 42c and the upper contact rib 42e.

[0017] The lower frame component 43 having the above-described configuration is attached to the metal frame portion 40 by locking the bent portion of the outer cover piece portion 43b to the upper cover groove portion 40j and inserting the inner insertion fin portion 43c into the lower resin frame insertion portion 40f. As is clear from the figure, in the metal frame portion 40 to which the lower frame component 43 is attached, the lower edge portion of the inner panel support portion 40e and the lower surface of the portion on the indoor side of the inner panel support portion 40e are covered by the lower frame component 43. The lower cover mounting piece 43d protrudes to the indoor side of the lower resin frame insertion portion 40f.

[0018] As shown in FIG. 4, when the upper frame component 42 and the lower frame component 43 are respectively attached to the metal frame portion 40, the upper cover mounting piece 42c and the lower cover mounting piece 43d are in a state of being inclined in a direction approaching each other, and the mutual distance gradually decreases from the base end portion to the protruding end portion.

[0019] The cover frame component 44 has a cover base 44a and two joining protrusions (clamping parts) 44b. The cover base 44a is a flat plate that extends vertically. As is clear from the figure, the width dimension of the cover base 44a along the vertical axis is configured to substantially coincide with the distance d1 from the upper surface of the upper cover mounting piece 42c to the lower surface of the lower cover mounting piece 43d when the upper cover mounting piece 42c and the lower cover mounting piece 43d are arranged parallel to each other. The joining protrusions 44b protrude outward from both the upper and lower edges of the cover base 44a and are configured to be hollow. The joining protrusion 44b provided on the upper edge of the cover base 44a is provided with an upper support surface 44c and an upper guide surface 44d, and the joining protrusion 44b provided on the lower edge of the cover base 44a is provided with a lower support surface 44e and a lower guide surface 44f. The upper support surface 44c extends substantially horizontally above the joint projection 44b, and the lower support surface 44e extends substantially horizontally below the joint projection 44b. The dimension d2 from the upper support surface 44c to the lower support surface 44e is set to substantially coincide with the distance from the upper contact rib 42e of the upper cover mounting piece 42c to the lower contact rib 43e of the lower cover mounting piece 43d when the upper cover mounting piece 42c and the lower cover mounting piece 43d are arranged parallel to each other. The upper guide surface 44d is provided on the outdoor side of the joint projection 44b and is inclined to gradually become downward from the upper support surface 44c toward the outside. The lower guide surface 44f is provided on the outdoor side of the joint projection 44b and is inclined to gradually become upward from the lower support surface 44e toward the outside. The dimension d3 from the outdoor-facing edge of the upper guide surface 44d to the outdoor-facing edge of the lower guide surface 44f is set to be smaller than the distance d4 between the upper contact rib 42e of the upper cover mounting piece 42c and the lower contact rib 43e of the lower cover mounting piece 43d, which are inclined relative to each other.

[0020] The cover frame component 44 is positioned by inserting two connecting protrusions 44b between the upper cover mounting piece 42c and the lower cover mounting piece 43d, and is attached between these upper cover mounting piece 42c and lower cover mounting piece 43d by screwing screw members (connectors) N1 into the connecting protrusions 44b via the upper cover mounting piece 42c and lower cover mounting piece 43d. Although not explicitly shown in the figure, the screw members N1 are screwed into multiple positions along the longitudinal side of the transom 14 with spacing between them. The visible surface of the metal frame portion 40 facing the interior is covered by the cover frame component 44 and is not visible from the interior side. The connecting protrusions 44b provided on the cover frame component 44 are configured to have dimensions in the depth direction that are smaller than those of the upper cover mounting piece 42c and lower cover mounting piece 43d, and are in a non-contact state with the upper insertion fin portion 42b, the inner insertion fin portion 43c, and the metal frame portion 40. To explain in more detail, the joint projection 44b of the cover frame component 44 is designed to ensure a gap of at least the thickness of the metal frame component 40 between it and the upper resin frame insertion portion 40c and the lower resin frame insertion portion 40f of the metal frame component 40. To give a specific numerical example, it is preferable to ensure a gap of more than 2 mm, but it is also acceptable to ensure a gap of 2 mm or less.

[0021] Here, when inserting the joint projection 44b between the upper cover mounting piece 42c and the lower cover mounting piece 43d, if the cover frame component 44 is pressed with the upper cover mounting piece 42c in contact with the upper guide surface 44d and the lower cover mounting piece 43d in contact with the lower guide surface 44f, the upper cover mounting piece 42c and the lower cover mounting piece 43d will elastically expand apart from each other due to the inclination action of the upper guide surface 44d and the lower guide surface 44f. When the protruding ends of the upper cover mounting piece 42c and the lower cover mounting piece 43d are in contact with the cover base 44a, the upper contact rib 42e is pressed against the upper support surface 44c, and the lower contact rib 43e is pressed against the lower support surface 44e. Therefore, in this state, even if you release your hand from the cover frame component 44, the cover frame component 44 is maintained in a fitted state by the pressing force from the upper cover mounting piece 42c and the lower cover mounting piece 43d. This makes it possible to simplify the installation work of the cover frame component 44, such as being able to operate a tool with one hand while gripping the screw member N1 with the other hand. Moreover, since the upper cover mounting piece 42c and the lower cover mounting piece 43d extend in a direction that is inclined toward each other, there is no concern that the parts of the screw member N1 located between them will curl up, and they will be in a state where they abut the joint projection 44b without any gaps along the entire length.

[0022] (Embodiment 2) Figures 6 and 7 show a joinery piece to which a frame profile, which is an embodiment 2 of the present invention, is applied. The joinery piece illustrated here is called a connected window, in which vertical sliding windows are arranged on the left and right sides inside a single frame 50. The frame 50 is composed of an outer perimeter frame section 50a formed by assembling an upper frame (horizontal frame) 51, a lower frame (horizontal frame) 52, and left and right vertical frames 53 around the perimeter, and a mullion (internal frame material) 54 provided to divide the internal space of the outer perimeter frame section 50a into two halves, left and right. In this frame 50, a sash 20 constituting the first vertical sliding window is arranged in the area enclosed by the upper frame 51, lower frame 52, left vertical frame 53, and mullion 54 so as to be openable to the outside, and a sash 20 constituting the second vertical sliding window is arranged in the area enclosed by the upper frame 51, lower frame 52, mullion 54, and right vertical frame 53 so as to be openable to the outside. The upper frame 51, lower frame 52, left and right vertical frames 53, and mullions 54 that constitute the frame body 50 are each composed of a metal frame portion formed from a metal such as an aluminum alloy and a resin frame portion formed from resin. The shoji screen 20 is constructed in the same manner as in Embodiment 1 by assembling an upper frame 22, a lower frame 23, and left and right vertical frames 24 around the four sides of a panel 21 made of double-glazed glass or the like, each forming a rectangular shape. The upper frame 22, lower frame 23, and left and right vertical frames 24 that constitute the shoji screen 20 are each composed of an exterior metal frame portion 25A formed from a metal such as an aluminum alloy and an interior resin frame portion 25B formed from resin. The following will mainly describe the configuration of the mullions 54 and also explain the characteristic features of the present invention.

[0023] As shown in Figures 7 to 10, the metal frame portion 60 of the mullion 54 has a six-part structure comprising a mullion core material 61, mullion reference molding portions 62 and attachment molding portions 63 provided on both the left and right sides of the mullion core material 61, and a connecting plate 64 provided on the portion extending to the interior side of the mullion core material 61 and the left and right mullion reference molding portions 62. The left and right mullion reference molding portions 62 and attachment molding portions 63 are configured to be symmetrical with respect to each other. For convenience, in the following explanation, the left and right positions will be specified with respect to the mullion core material 61 as the center. That is, the direction close to the mullion core material 61 will be referred to as the center side, and the direction away from the mullion core material 61 will be referred to as the periphery side.

[0024] The vertical core material 61 has a base plate portion 61a, a support plate portion 61b, and a connecting piece 61c. The base plate portion 61a is a flat plate that extends vertically along the depth direction. The support plate portion 61b is provided on the outer edge of the base plate portion 61a, extends vertically along the width direction, and protrudes to the left and right of the base plate portion 61a. The connecting piece 61c extends inward from the inner edge of the base plate portion 61a, then bends and extends in the width direction.

[0025] The mullion reference molded section 62 is formed by integrally molding a metal frame body 62a, an outer visible wall section 62b, and an inner visible wall section 62c. The metal frame body 62a is a flat plate shape that extends almost vertically along the depth direction. The dimensions of the metal frame body 62a along the depth direction are smaller than the dimensions from the connecting piece 61c to the support plate section 61b in the mullion core material 61. The outer visible wall section 62b extends along the visible direction at the edge located on the outdoor side of the metal frame body 62a. The inner visible wall section 62c extends along the visible direction at the edge located on the indoor side of the metal frame body 62a, and its center side is bent outwards. A resin frame insertion section 62d that opens outwards is provided in the portion located on the periphery side of the inner visible wall section 62c.

[0026] The attachment molding section 63 is integrally molded with the attachment body 63a, outer support wall section 63b, inner support wall section 63c, door stop component wall section 63d, and central resin frame insertion groove section 63e. The attachment body 63a is a flat plate shape that extends vertically along the depth direction. The length of the attachment body 63a along the depth direction is smaller than the metal frame body 62a of the mullion reference molding section 62. The outer support wall section 63b extends in the visible direction from the edge located on the outdoor side of the attachment body 63a toward the center. The dimension of the outer support wall section 63b along the visible direction is approximately the same as the length of the portion of the outer visible wall section 62b that extends toward the periphery beyond the metal frame body 62a. The inner support wall section 63c extends in the visible direction from the edge located on the indoor side of the attachment body 63a toward the center, and then bends toward the outdoor side. The dimensions of the inner support wall portion 63c along the visible direction are approximately the same as those of the outer support wall portion 63b. A sealing member S2 is attached to the central part of the inner support wall portion 63c. The door stop component wall portion 63d extends in the visible direction from the edge located on the indoor side of the attachment body 63a toward the periphery. A sealing member S3 is attached to the portion of the periphery edge of the door stop component wall portion 63d that faces the outside. A periphery side resin frame insertion groove portion 63f, which opens toward the periphery, is provided on the periphery side resin frame insertion groove portion 63f, which faces toward the periphery, on the periphery side resin frame insertion groove portion 63e is provided in the middle part of the visible surface located on the indoor side of the door stop component wall portion 63d and opens toward the periphery.

[0027] The attachment molding section 63 described above is connected to the mullion reference molding section 62 by bringing the exterior-facing surface of the exterior-facing wall section 63b into contact with the interior-facing surface of the exterior-facing wall section 62b, and bringing the interior-facing wall section 63c into contact with the periphery-facing surface of the metal frame body 62a, and then screwing the screw member N2 into the bent portion of the interior-facing wall section 63c via the metal frame body 62a.

[0028] The connecting plate 64 is a plate-shaped member for connecting the connecting piece 61c of the mullion core material 61 and the inner visible wall portion 62c of the left and right mullion reference molded portions 62 to each other. On the surface of the connecting plate 64 facing the outside, ribs 64a are provided on the left and right sides to define the mounting position of the mullion reference molded portion 62 to the mullion core material 61.

[0029] The metal frame portion 60 having the above-described configuration is connected to each other by arranging mullion reference molding portions 62, which are integrated with attachment molding portions 63, on both sides of the mullion core material 61, screwing screw members N3 into the connecting piece 61c via a connecting plate 64, and screwing screw members N4 into the inner visible wall portions 62c via the connecting plate 64. Furthermore, the support plate portion 61b faces the outer visible wall portion 62b on the outdoor side of the outer visible wall portion 62b, and by interposing an elastic member 61d between them, the position of the attachment molding portion 63 relative to the mullion core material 61 is defined.

[0030] The resin frame portion 70 of the mullion 54 has a three-part structure consisting of left and right frame components 71 and a cover frame component (cover member) 72 provided between the left and right frame components 71.

[0031] The frame structure 71 is symmetrical on the left and right sides, and is formed by integrally molding a resin frame body 71a, a frame cover 71b, an inward insertion fin 71c, an outward insertion fin 71d, and a cover mounting piece 71e. The resin frame body 71a has a hollow shape with an irregular cross-section. The frame cover 71b extends outward from the edge on the periphery side of the resin frame body 71a, which is on the outdoor side. A cover projection 71f is provided on the central side of the frame cover 71b, facing towards the center. The inward insertion fin 71c extends outward from the edge on the central side of the resin frame body 71a, which is on the indoor side. The outward insertion fin 71d protrudes outward from the edge on the central side of the resin frame body 71a, which is on the outdoor side, and then bends towards the center. The cover mounting piece 71e extends in an inclined manner from the central part of the visible surface of the resin frame body 71a facing the interior of the room, gradually moving towards the center inwards. The protruding end of the cover mounting piece 71e is provided with a contact rib 71g that protrudes toward the center.

[0032] The frame component 71 is attached to the metal frame 60 by inserting the cover projection 71f into the surrounding resin frame insertion groove 63f, inserting the inward insertion fin 71c into the resin frame insertion part 62d, and then crimping the resin frame insertion part 62d. As is clear from the figure, in the metal frame 60 to which the frame component 71 is attached, the visible surface on the surrounding side of the door stop component wall 63d, the visible surface of the door stop component wall 63d facing the interior, and the surrounding side of the portion of the metal frame body 62a that protrudes inward from the attachment molding part 63 are covered by the frame component 71. The cover mounting piece 71e protrudes inward from the resin frame insertion part 62d and is inclined toward a direction toward proximity to each other, with the distance between them gradually decreasing from the base end to the protruding end.

[0033] The cover frame component 72 has a cover base 72a and two joining protrusions (clamping parts) 72b. The cover base 72a is a flat plate that extends from left to right. As is clear from the figure, the width dimension of the cover base 72a along the left and right sides is configured to substantially coincide with the distance d5 from the surface located on the periphery side of one cover mounting piece 71e to the surface located on the periphery side of the other cover mounting piece 71e when the left and right cover mounting pieces 71e are arranged parallel to each other. The joining protrusions 72b are hollow and protrude outward from both the left and right edges of the cover base 72a, and are configured to be symmetrical. The joining protrusions 72b are provided with a support surface 72c and a guide surface 72d. The support surface 72c extends substantially vertically along the depth direction on the periphery side of the joining protrusions 72b. The dimension d6 from one support surface 72c to the other support surface 72c is set to approximately coincide with the distance from the contact rib 71g of one cover mounting piece 71e to the contact rib 71g of the other cover mounting piece 71e when the left and right cover mounting pieces 71e are arranged parallel to each other. The guide surface 72d is provided on the outdoor side of the joint projection 72b and is inclined so as to gradually move towards the center from the support surface 72c outwards. The dimension d7 from the outdoor side edge of one guide surface 72d to the outdoor side edge of the other guide surface 72d is set to be smaller than the distance d8 between the contact ribs 71g of the left and right cover mounting pieces 71e, which are inclined relative to each other.

[0034] The cover frame component 72 is positioned by inserting two connecting protrusions 72b between the cover mounting pieces 71e, and is attached between the cover mounting pieces 71e by screwing screw members (connectors) N5 into the connecting protrusions 72b via each cover mounting piece 71e. Although not explicitly shown in the figure, the screw members N5 are screwed into multiple positions along the longitudinal side of the mullion 54, with spacing between them. The visible surface of the metal frame 60 facing the interior is covered by the cover frame component 72, so there is no risk of it being visible from the interior. The connecting protrusions 72b provided on the cover frame component 72 are configured to have a dimension smaller than that of the cover mounting pieces 71e in the depth direction, and are in a non-contact state with both the inward insertion fin portion 71c and the metal frame 60. To explain in more detail, the joint projection 72b of the cover frame component 72 is designed to ensure a gap between it and the resin frame insertion portion 62d of the metal frame portion 60 that is greater than or equal to the thickness of the metal frame portion 60. To give a specific numerical example, it is preferable to ensure a gap of more than 2 mm, but it is also acceptable to ensure a gap of 2 mm or less.

[0035] Here, when inserting the joint projection 72b between the left and right cover mounting pieces 71e, pressing the cover frame component 72 with each cover mounting piece 71e in contact with the guide surface 72d will cause the left and right cover mounting pieces 71e to elastically expand apart due to the inclination action of the guide surface 72d. When the protruding ends of the cover mounting pieces 71e are in contact with the cover base 72a, the contact ribs 71g are pressed against the support surface 72c. Therefore, in this state, even if you release your hand from the cover frame component 72, the cover frame component 72 will remain fitted in place due to the pressing force from the left and right cover mounting pieces 71e. This makes it possible to simplify the installation of the cover frame component 72, for example, by being able to hold the screw member N5 with one hand while operating a tool with the other. Furthermore, since the left and right cover mounting pieces 71e extend in a direction that is inclined toward each other, there is no concern that the parts located between the screw members N5 will curl up, and they will be in a state where they abut the joint projection 72b without any gaps along their entire length.

[0036] In the embodiments described above, the distance between the two cover mounting pieces is gradually reduced by inclining each of them, but it is sufficient if at least one of the cover mounting pieces extends in an inclined manner. Furthermore, although examples are given of joinery where the cover member is provided only on the central frame material such as the transom or mullion, it is not necessarily limited to the central frame material, and it can also be applied to joinery where the cover member is provided on multiple frame materials. In the case of application to the transom, a stepped window consisting of a vertical sliding window and a fixed window is given as an example, but the types of windows provided above and below the transom are not limited to these. Similarly, in the case of application to the mullion, a series of vertical sliding windows is given as an example, but the types of windows provided on the left and right of the mullion are not limited to those in the embodiment. Furthermore, although resin frame parts are attached to both sides of the metal frame part, and the cover member is provided between the cover mounting pieces provided on each resin frame part, the present invention is not limited to this. For example, each single resin frame part may have a cover mounting piece. Furthermore, although an example is given in which the cover member is attached to the visible surface of the frame material, the cover member may also be attached to the depth surface of the frame material. The connector provided between the cover member and the cover clamping piece does not necessarily have to be a screw member.

[0037] As described above, the joinery according to the present invention comprises, at least one of the frame materials constituting the frame body, a resin frame portion molded from resin, and a cover member supported by the resin frame portion, wherein the resin frame portion is provided with two cover mounting pieces facing each other, the cover member is provided with clamping portions arranged between the cover mounting pieces, and a connector is provided on the clamping portions via the cover mounting pieces, wherein the cover mounting pieces extend so as to gradually decrease in the distance between them toward the protruding ends, and the clamping portions are arranged between them in an expanded state. According to this invention, when attaching the cover member, the clamping portion can be fitted between the cover mounting pieces, eliminating the need to hold the cover member in place by hand. Therefore, the attachment work of the cover member can be made easier, for example, by allowing the user to hold the connector with one hand while operating a tool with the other.

[0038] Furthermore, the joinery according to the present invention comprises, at least one of the frame materials constituting the frame body, a metal frame portion formed from metal, two resin frame portions formed from resin and attached to both sides of the metal frame portion, and a cover member provided between the two resin frame portions, wherein the two resin frame portions are each provided with cover mounting pieces facing each other, the cover member is provided with clamping portions arranged between the cover mounting pieces, and a connector is provided between the clamping portions via the cover mounting pieces, wherein the cover mounting pieces extend so as to gradually decrease in distance from each other toward the protruding ends, and the clamping portions are arranged between them in an expanded state. According to this invention, when attaching the cover member, the clamping portion can be fitted between the cover mounting pieces, eliminating the need to hold the cover member in place by hand. Therefore, the attachment work of the cover member can be made easier, for example, by allowing the user to hold the connector with one hand while operating a tool with the other.

[0039] Furthermore, the present invention is characterized in that, in the above-described joinery, the frame body comprises an outer perimeter frame portion formed by assembling upper and lower horizontal frames and left and right vertical frames around the perimeter, and a central frame member provided to divide the internal space of the outer perimeter frame portion, wherein the central frame member comprises the resin frame portion and the cover member. According to this invention, the process of attaching the cover member to the central frame material can be made easier.

[0040] Furthermore, the present invention is characterized in that, in the above-described joinery, the cover member has a cover base that is in the shape of a flat plate and a clamping portion that extends from the cover base toward the outside, and the clamping portion has two joining protrusions that protrude from both side edges of the cover base. According to this invention, a space can be secured between the metal frame and the cover base, which is advantageous in terms of heat insulation.

[0041] Furthermore, the present invention is characterized in that, in the above-described joinery, when the cover member is supported by the resin frame, a gap is secured between the two joint protrusions and the metal frame. According to this invention, the metal frame and the cover member are in a non-contact state, which is advantageous in terms of heat insulation.
