Summary of the Invention

Problems to be Solved by the Invention

[0004] Generally, the expected dimensions of the glass pressing component correspond to the thicknesses of the glass and the door body main body. Therefore, when the glass or the door body main body is changed to one with a larger thickness, the same glass pressing component cannot be used, and it is necessary to produce a new glass pressing component to cope with it.

[0005] Therefore, an object of the present disclosure is to provide a glass pressing component that can sandwich a glass plate using a common member even when the thicknesses of the glass and the door body main body are different, a door body having the glass pressing component, and a fitting.

[0008] The embodiments of this disclosure will now be described in detail with reference to the drawings. Figures 1 and 2 show a joinery 1 according to this embodiment. The joinery 1 according to this embodiment is an example of an entrance door. The joinery 1 has a frame 2 provided in a structural opening 101 formed in the building frame 100. A door 3 is attached to the inside of the frame 2 so as to be openable and closable via a plurality of hinges 25.

[0009] Here, the directions in the fitting 1 are defined as follows. The X1 direction indicated by the arrow in the figure indicates the outdoor side, and the X2 direction indicates the indoor side. In the fitting 1, the indoor-outdoor direction connecting the outdoor side X1 and the indoor side X2 is called the prospective direction. In the fitting 1, the surface arranged along the prospective direction is called the prospective surface. In the fitting 1, the direction that is orthogonal to the prospective direction and connects the inside and outside of the frame of the frame body 2 is called the finding direction. In the fitting 1, the surface arranged along the finding direction is called the finding surface. The left-right direction in the fitting 1 is the left-right direction when the fitting 1 is viewed from the indoor side X2. Therefore, when the fitting 1 is viewed from the indoor side X2, the left hand side is "left" and the right hand side is "right". In the fitting 1, the side facing the inside of the frame body 2 along the finding direction is the inner side, and the side facing the outside of the frame body 2 along the finding direction is the outer side.

[0010] The frame body 2 is configured by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23 and 24 into a rectangle.

[0011] The upper frame 21 is made of an extruded profile made of metal such as aluminum. As shown in FIG. 3, it is formed in a rectangular cross-section having an upper wall portion 21a, a lower wall portion 21b, an outdoor wall portion 21c, and an indoor wall portion 21d, and has a hollow portion 21e inside. The lower wall portion 21b is arranged to face the upper end prospective surface 3a of the door body 3 when closed. The upper frame 21 has a first attachment piece portion 21f and a second attachment piece portion 21g. The first attachment piece portion 21f is formed by extending the indoor wall portion 21d outside the upper wall portion 21a. The second attachment piece portion 21g is formed by extending the lower wall portion 21b to the indoor side X2.

[0012] The second attachment piece portion 21g is formed with an outer protruding piece 21h that protrudes outward. The outer protruding piece 21h is disposed on the outdoor side X1 rather than at the outermost end on the indoor side X2 of the second attachment piece portion 21g, and is erected vertically outward. Further, the second attachment piece portion 21g is formed with an inner protruding piece 21i that protrudes inward. The inner protruding piece 21i is erected vertically inward from a portion between the outer protruding piece 21h and the indoor wall portion 21d in the second attachment piece portion 21g. An upper frame side airtight material 210 is attached to the surface on the outdoor side X1 of the inner protruding piece 21i. The upper frame side airtight material 210 contacts the surface 3b on the indoor side X2 at the upper end portion of the door body 3 when closed, and keeps the space between it and the door body 3 airtight when closed.

[0013] The upper frame 21 is fixed to the outdoor side surface 100a by a screw SC1 that penetrates the first attachment piece portion 21f from the outdoor side X1 in a state where the first attachment piece portion 21f is abutted against the outdoor side surface 100a of the building body 100. Further, the upper frame 21 is fixed to the upper inner peripheral surface 101a by a screw SC2 that penetrates the second attachment piece portion 21g and the plate material 110 from the inside in a state where the outer protruding piece 21h of the second attachment piece portion 21g is abutted against the upper inner peripheral surface 101a of the housing opening 101 via the plate material 110 for interval adjustment. A waterproof tape 111 is attached to the surface on the outdoor side X1 of the first attachment piece portion 21f so as to cover the head of the screw SC1. The gap between the upper wall portion 21a of the upper frame 21 and the exterior material 112 provided on the outdoor side X1 of the building body 100 is sealed by a sealing material 113.

[0014] The second attachment piece portion 21g constitutes an angle portion 21g1 by a portion on the indoor side X2 rather than the outer protruding piece 21h. The angle portion 21g1 sandwiches an upper forehead edge member 120a disposed on the indoor side X2 of the outer protruding piece 21h in the vertical direction between the plate material 110. The angle portion 21g1 is fixed to the upper forehead edge member 120a by a screw SC3 that penetrates the angle portion 21g1 from the inside.

[0015] The lower frame 22 is made of an extruded metal profile such as aluminum, and as shown in Figure 3, it is composed of a lower frame body 22a, an inner projection piece 22b, and an indoor extension piece 22c. The lower frame body 22a is formed in a flat plate shape that extends in the indoor-outward direction and is positioned to face the lower end projection surface 3c of the door body 3 when closed. The inner projection piece 22b has a shape in which the indoor end X2 of the lower frame body 22a is bent inward at a right angle. The inner projection piece 22b is positioned directly below the inner projection piece 21i of the upper frame 21. A lower frame side airtight material 220 is attached to the outdoor side X1 surface of the inner projection piece 22b. The lower frame side airtight material 220 contacts the indoor side X2 surface 3b of the lower end of the door body 3 when closed, and maintains an airtight seal between the door body 3 and the lower frame side airtight material 220 when closed.

[0016] The indoor extension piece 22c extends from the inner projection piece 22b toward the indoor side X2. The inner projection piece 22b protrudes further inward than the indoor extension piece 22c. At the indoor side X2 end of the indoor extension piece 22c, a vertical wall portion 22d is formed, which is bent inward at a right angle to the same height as the inner projection piece 22b. As a result, a groove portion 22e is formed at the indoor side X2 end of the lower frame 22, consisting of the inner projection piece 22b, the indoor extension piece 22c, and the vertical wall portion 22d. A protective member 221 made of rubber, comb, or resin is fitted into the groove portion 22e. The upper surface of the protective member 221 is positioned to be flush with the floor surface FL of the indoor side X2. The protective member 221 prevents the upper surface of the indoor side X2 from being damaged by the adhesion of sand, etc., and also prevents condensation from occurring on the indoor side X2 than the door body 3.

[0017] An outdoor leg portion 22f is formed at the outdoor end X1 of the lower frame body 22a, having a shape that is bent at a right angle toward the outside. An indoor leg portion 22g is formed at the indoor end X2 of the lower frame body 22a, with the vertical wall portion 22d extending toward the outside. The outdoor leg portion 22f and the indoor leg portion 22g protrude toward the outside at the same height. The lower frame 22 is placed on the lower surface 101b of the building frame opening 101 by the outdoor leg portion 22f and the indoor leg portion 22g.

[0018] The left and right pair of vertical frames 23 and 24 have the same structure and are provided symmetrically on the frame body 2. Vertical frame 23 is the left vertical frame when viewing the door 1 from the interior side X2 and is positioned on the hinge side of the door body 3 when closed. Vertical frame 24 is the right vertical frame when viewing the door 1 from the interior side X2 and is positioned on the leading edge side of the door body 3 when closed.

[0019] As shown in Figure 4, the vertical frames 23 and 24 are formed in a rectangular cross-section having outer wall portions 23a and 24a, inner wall portions 23b and 24b, exterior wall portions 23c and 24c, and interior wall portions 23d and 24d, and have hollow portions 23e and 24e inside. The inner wall portion 23b of the vertical frame 23 is positioned to face the hinge-side projection surface 3d of the door body 3 when closed, and the inner wall portion 24b of the vertical frame 24 is positioned to face the door-edge-side projection surface 3e of the door body 3 when closed. The vertical frames 23 and 24 have first mounting pieces 23f and 24f and second mounting pieces 23g and 24g. The first mounting pieces 23f and 24f are formed by extending the interior wall portions 23d and 24d outward beyond the outer wall portions 23a and 24a. The second mounting pieces 23g and 24g are formed by extending the inner wall portions 23b and 24b toward the interior side X2.

[0020] The second mounting pieces 23g and 24g have outwardly projecting outer projection pieces 23h and 24h formed on them. The outward projection pieces 23h and 24h are positioned on the outdoor side X1 beyond the outermost end of the indoor side X2 of the second mounting pieces 23g and 24g, and are erected vertically toward the outside. Furthermore, the second mounting pieces 23g and 24g have inwardly projecting inner projection pieces 23i and 24i formed on them. The inward projection pieces 23i and 24i are erected vertically toward the inside from the portion of the second mounting pieces 23g and 24g between the outward projection pieces 23h and 24h and the indoor wall portions 23d and 24d. Vertical frame side airtight materials 230 and 240 are attached to the outdoor side X1 surface of the inner projection pieces 23i and 24i. The vertical frame side airtight materials 230 and 240 contact the interior side surface X2 3b of the hinge side end and door edge end of the door body 3 when closed, respectively, and maintain an airtight seal between them and the door body 3 when closed.

[0021] The vertical frames 23 and 24 are fixed to the exterior side surface 100a of the building frame 100 by screws SC4 that penetrate the first mounting pieces 23f and 24f from the exterior side X1, with the first mounting pieces 23f and 24f in contact with the exterior side surface 100a of the building frame 100. Furthermore, the vertical frames 23 and 24 are fixed to the interior side surface 101c of the vertical section 101c of the building frame opening 101 by screws SC5 that penetrate the second mounting pieces 23g and 24g from the inside, with the outer protruding pieces 23h and 24h of the second mounting pieces 23g and 24g in contact with the interior side surface 101c of the building frame opening 101. Waterproof tape 111 is attached to the exterior side X1 surface of the first mounting pieces 23f and 24f so as to cover the heads of the screws SC4. The gap between the outer wall portions 23a and 24a of the vertical frames 23 and 24 and the exterior material 112 provided on the exterior side X1 of the building frame 100 is sealed with a sealant 113.

[0022] The second mounting pieces 23g and 24g form angle portions 23g1 and 24g1, respectively, with the portion on the indoor side X2 of the outer protruding pieces 23h and 24h being the same as the angle portions 23g1 and 24g1. The angle portions 23g1 and 24g1 sandwich the vertical frame member 120b, which is positioned on the indoor side X2 of the outer protruding pieces 23h and 24h, between themselves and the inner circumferential surface 101c of the vertical part of the building opening 101 in the left-right direction. The angle portions 23g1 and 24g1 are fixed to the vertical frame member 120b by screws SC6 that penetrate the angle portions 23g1 and 24g1 from the inside.

[0023] Next, the door panel 3 will be described. As shown in Figures 1 and 2, the door panel 3 is assembled into a rectangle that fits inside the frame 2. An exterior handle 30a and an interior handle 30b are attached to the leading edge of the door panel 3. Cylinder locks 30c, 30c are provided above and below the exterior handle 30a and the interior handle 30b, respectively.

[0024] As shown in Figure 4, the door panel 3 is attached to the vertical frame 23 by a hinge 25 on the hinge side (left side in Figure 4). One wing portion 25a of the hinge 25 is attached to the hinge side facing surface 3d of the door panel 3, and the other wing portion 25b of the hinge 25 is attached to the inner wall portion 23b of the vertical frame 23. The pivot axis 25c of the hinge 25 is positioned to protrude outward from the exterior side X1 beyond the exterior side X1 surface 3f of the door panel 3. The door panel 3 opens towards the exterior side X1 around the pivot axis 25c of the hinge 25 to open the building opening 101, and closes towards the interior side X2 so that the door edge side facing surface 3e faces the inner wall portion 24b of the vertical frame 24 to close the building opening 101.

[0025] The door body 3 is composed of a door body 30 having a rectangular opening 31 in the center, and glass G that is fitted into the opening 31. As shown in Figures 4 and 5, an opening core material 32 is provided on the periphery of the opening 31 in the door body 30. As shown in Figure 7, the opening core material 32 is composed of a U-shaped resin core material 321 and a U-shaped metal core material 322 provided along the outer surface of the resin core material 321. The opening core material 32 extends along the left-right direction at the top of the opening 31, the left-right direction at the bottom, and the up-down direction at the top of the vertical part, and is assembled into a vertically elongated rectangle. The inner circumferential surface of the rectangularly assembled opening core material 32 is a flat surface, forming the visible surface 32a of the opening core material 32. The opening core material 32 is sandwiched between steel plates 33a and 33b, which are the surface material of the door body 30. The steel plates 33a and 33b constitute the exterior surface X1 3f and the interior surface X2 3b of the door body 3.

[0026] The glass G is housed inside the opening core material 32 via a glass retaining component 4, which will be described later. The glass G is composed of three glass plates G1 to G3 stacked with a spacer GS in between. The outer edges of the glass G face the visible surface 32a of the opening core material 32 at a predetermined distance.

[0027] The glass retaining component 4 is positioned between the opening core material 32 and the glass G, along the periphery of the glass G. That is, the glass retaining component 4 extends along the left-right direction at the top of the opening 31, the left-right direction at the bottom, and the up-down direction at the top of the vertical part, and is assembled into a vertically elongated rectangle. The glass retaining component 4 supports the glass G in the opening 31 by clamping the periphery of the glass G in the in-room and out-of-room directions, and also functions as a frame member of the door body 3 that conceals the periphery of the opening 31 and the periphery of the glass G, thereby improving the design of the joinery 1 and the door body 3.

[0028] The glass retaining parts 4 have substantially the same structure except for their length. Therefore, they will be described in detail with reference to the glass retaining parts 4 located at the bottom of the opening 31 shown in Figures 7 and 8.

[0029] The glass retaining component 4 comprises an outdoor retaining member 41, an indoor retaining member 42, and a fixing screw 43. The outdoor retaining member 41 is positioned on the outdoor side X1 of the peripheral edge of the glass G. The indoor retaining member 42 is positioned on the indoor side X2 of the peripheral edge of the glass G. Specifically, the outdoor retaining member 41 extends from the outdoor side X1 to the indoor side X2 between the glass G and the opening core material 32. The indoor retaining member 42 extends from the indoor side X2 to the outdoor side X1 between the glass G and the opening core material 32.

[0030] The outdoor-side retaining member 41 is made of an extruded metal profile such as aluminum and is a component that constitutes the outer frame member of the glass retaining part 4, which is a frame member. The outdoor-side retaining member 41 integrally has a decorative panel portion 411 that is positioned facing the outdoor side X1 and a projection plate portion 412 that extends from the decorative panel portion 411 toward the indoor side X2 between the glass G and the opening core material 32.

[0031] The decorative panel portion 411 extends from the outdoor-facing surface X1 Ga of the peripheral edge of the glass G to the steel plate 33a on the outdoor-facing side X1 of the door body 3, and is located outside the opening 31, constituting the decorative material on the outdoor-facing side X1 of the glass retaining component 4. The inner end of the decorative panel portion 411 bends at a right angle toward the indoor-facing side X2, forming a retaining portion 411a that presses against the outdoor-facing surface X1 Ga of the glass G. An outdoor-facing glass contact portion 411b made of rubber or resin is attached to the indoor-facing end X2 of the retaining portion 411a that contacts the glass G.

[0032] The facing plate portion 412 extends from the decorative plate portion 411 towards the interior side X2 between the glass G and the opening core material 32. The facing plate portion 412 has a connecting portion 412a, a rising portion 412b, a glass support portion 412c, and a screw fixing groove portion 412d.

[0033] The connecting portion 412a is connected to the decorative panel portion 411 and extends toward the indoor side X2. The indoor side end of the connecting portion 412a is positioned on the outdoor side X1 of the glass G, relative to the outdoor side surface Ga, and is connected to the rising portion 412b. The rising portion 412b rises inward from the indoor side end of the connecting portion 412a. The glass support portion 412c extends from the inner end of the rising portion 412b toward the indoor side X2, parallel to the end face Gc of the glass G. The screw fixing groove portion 412d is connected to the indoor side X2 end of the glass support portion 412c and opens toward the indoor side X2. The screw fixing groove portion 412d is positioned between the glass G and the opening core material 32, corresponding to the center of the thickness of the glass G. A protruding piece 412e is integrally formed at the indoor side X2 end of the facing plate portion 412 (the indoor side X2 end of the screw fixing groove portion 412d), which protrudes toward the end face Gc of the glass G.

[0034] The glass support portion 412c is positioned opposite the end face Gc of the glass G with a gap between them. A foamed resin sheet 414 and a setting block 415 are positioned on the inner surface of the glass support portion 412c via an L-shaped metal piece 413, sealing the space between the glass support portion 412c and the end face Gc of the glass G. The rising portion 413a of the L-shaped metal piece 413 is positioned on the outdoor side X1 of the glass G, and rises inward from the position of the end face Gc of the glass G. The foamed resin sheet 414 and the setting block 415 are positioned between the rising portion 413a of the L-shaped metal piece 413 and the protruding portion 412e of the facing plate portion 412, with the setting block 415 facing the glass G side. The L-shaped metal piece 413 and the foamed resin sheet 414 are fixed to the glass support portion 412c by screws 416 that are screwed from the inside into tapping holes 412c1 formed in the glass support portion 412c.

[0035] The indoor side retaining member 42 is a component that constitutes the inner frame member of the glass retaining part 4, which is a frame member. The indoor side retaining member 42 is composed of a retaining member body 421, a spacer member 422 positioned on the outdoor side X1 of the retaining member body 421, and a cover member 423 that covers the retaining member body 421 from the indoor side X2. The retaining member body 421, the spacer member 422, and the cover member 423 are each separate components.

[0036] As shown in Figure 9, the retaining member body 421 is made of an extruded profile having a metal core material 421b inside a hard resin member 421a, and is a conventionally used member. The retaining member body 421 has a base portion 4211 that extends outward from the interior side surface X2 Gb of the periphery of the glass G along the interior side steel plate 33b of the door body 3, and three hollow portions: a first hollow portion 4212a, a second hollow portion 4212b, and a third hollow portion 4212c. The core material 421b is embedded in the base portion 4211.

[0037] The base portion 4211 has a bent portion 421c that is bent in a crank shape in the indoor-outdoor direction, near the approximate center of the visible direction of the base portion 4211, such that its inner end is positioned on the outdoor side X1. The first hollow portion 4212a and the second hollow portion 4212b are positioned adjacent to each other on the inside and outside, with the bent portion 421c in between. The first hollow portion 4212a is positioned on the indoor side X2 of the core material 421b and is formed to protrude from the base portion 4211 to the indoor side X2. The second hollow portion 4212b is positioned on the outdoor side X1 of the core material 421b and is formed to protrude from the base portion 4211 to the outdoor side X1. The third hollow portion 4212c is positioned adjacent to the outside of the second hollow portion 4212b on the indoor side X2 of the core material 421b and is formed to protrude from the base portion 4211 to the indoor side X2.

[0038] On the outdoor-facing X1 surface at the inner end of the base 4211, an indoor-facing glass contact portion 4213 made of a rubber or resin material softer than the base 4211 is provided, protruding toward the outdoor-facing X1. The indoor-facing glass contact portion 4213 has a plurality of fin portions 4213a that protrude diagonally inward toward the outdoor-facing X1. On the indoor-facing X2 surface at the inner end of the base 4211, a projection 4214 protruding toward the indoor-facing X2 is integrally formed by a resin member 421a. Between the projection 4214 and the first hollow portion 4212a, a soft layer portion 4215 made of a rubber or resin material softer than the base 4211 is laminated. On the outdoor-facing surface 4211a of the base 4211 corresponding to the second hollow portion 4212b, two soft projections 4216, 4216 made of a rubber or resin material softer than the base 4211 are provided. The two soft protrusions 4216, 4216 are positioned along the inner and outer ends of the exterior surface 4211a, respectively, and protrude toward the exterior side X1.

[0039] On the outer end of the base portion 4211, a steel plate contact portion 4217 is integrally formed by a resin member 421a on the outdoor side X1 surface, projecting toward the outdoor side X1. Inside the steel plate contact portion 4217, a fin-shaped steel plate contact portion 4218 made of a rubber or resin material softer than the base portion 4211 is provided. The steel plate contact portion 4218 projects diagonally inward toward the outdoor side X1 from the corner between the steel plate contact portion 4217 and the base portion 4211.

[0040] As shown in Figures 7 and 8, the retaining member body 421 is integrally fixed to the outdoor retaining member 41 by screwing a fixing screw 43, which is inserted from the indoor side X2 and passes through the retaining member body 421 and the spacer member 422, into the screw fixing groove portion 412d of the outdoor retaining member 41. As shown in Figure 9, the retaining member body 421 has through holes 4219 for screw insertion that penetrate the second hollow portion 4212b in the indoor-outdoor direction, which are created by post-processing. Multiple through holes 4219 are provided along the length of the retaining member body 421 at predetermined intervals. Two soft protrusions 4216, 4216 are arranged to sandwich the through holes 4219 from the inside and outside. The retaining member body 421 has a V-groove shaped notch portion 4219a formed along the length of the retaining member body 421, which serves as a mark (hole center position) for processing the through holes 4219.

[0041] The spacer member 422 is positioned between the screw fixing groove 412d of the outdoor side retaining member 41 and the retaining member body 421 of the indoor side retaining member 42, between the glass G and the opening core material 32. The spacer member 422 is made of resin or metal. Specifically, the spacer member 422 is made of an extruded profile formed from a hard resin material similar to the resin material 421a of the retaining member body 421 or from a metal material such as aluminum. As shown in Figure 10, the spacer member 422 has a spacer member body 4221 with a horizontally elongated rectangular cross-section that is long in the indoor-outdoor direction, and two hollow sections, a first hollow section 422a and a second hollow section 422b, which are separated in the indoor-outdoor direction by the partition wall 4222. Therefore, the spacer member 422 has excellent strength and heat insulation properties.

[0042] The partition wall 4222 extends along the facing direction of the spacer member body 4221. The first hollow portion 422a and the second hollow portion 422b are formed inside the spacer member body 4221, flanking the partition wall 4222, and arranged in the indoor-outdoor direction. In particular, when the spacer member 422 supports the lower end face Gc of the glass G, as shown in Figure 7, the partition wall 4222 can firmly support the load of the glass G. A projection 422a1 with a rectangular cross-section is provided on the inner surface of the first hollow portion 422a, as shown in Figure 10.

[0043] A projection 4223 is integrally formed at the outdoor-facing end X1 of the spacer member 422. The projection 4223 is the part that is inserted into the screw fixing groove 412d of the outdoor-facing retaining member 41, and it protrudes in a plate-like shape from the outdoor-facing end face 4221a of the spacer member body 4221 toward the outdoor-facing X1. Two soft projections 4224, 4224 made of a softer rubber or resin material than the spacer member body 4221 are formed at the inner and outer ends of the outdoor-facing end face 4221a so as to sandwich the projection 4223 from the inside and outside.

[0044] A water-repellent portion 4225 is integrally formed at the indoor-side X2 end of the spacer member 422, projecting inward. The water-repellent portion 4225 is formed to project in a wall-like manner from the indoor-side X2 end of the spacer member body 4221 toward the indoor-side X2 and inward. The water-repellent portion 4225 prevents water that seeps between the spacer member body 4221 and the glass G toward the indoor-side X2 from flowing out to the retaining member body 421.

[0045] A protruding base portion 4226 is integrally formed at the indoor side X2 end of the spacer member 422. The protruding base portion 4226 is the part that abuts against the outdoor side surface 4211a of the retaining member body 421 when it is fixed to the retaining member body 421, and protrudes toward the indoor side X2 from the indoor side end surface 4221b of the spacer member body 4221.

[0046] On the outer surface 4221c of the spacer member 422, which is the surface opposite to the surface facing the glass G, a rectangular cross-section projection 4227 is integrally formed. On the inner surface 4221d of the spacer member 422, which is the surface facing the glass G, a foamed resin sheet 424 and a setting block 425 are arranged, as shown in Figure 7, to fill the space between the spacer member 422 and the end face Gc of the glass G. The foamed resin sheet 424 is attached to the inner surface 4221d. In contrast, the outer surface 4221c has the projection 4227, which prevents the foamed resin sheet from being mistakenly attached by the worker.

[0047] As shown in Figures 7 and 8, the spacer member 422 is fixed between the retaining member body 421 and the outdoor retaining member 41 by fixing screws 43 that are inserted from the indoor side X2 and pass through the retaining member body 421 and the spacer member 422. As shown in Figure 10, the spacer member 422 has through holes 4228 for screw insertion that pass through the spacer member body 4221, extending from the outdoor end face 4221a to the indoor end face 4221b of the spacer member body 4221, which are created by post-processing. Multiple through holes 4228 are provided at predetermined intervals along the length direction, in line with the position of the through holes 4219 of the retaining member body 421. The two soft protrusions 4224, 4224 are arranged to sandwich the through holes 4228 from the inside and outside. Since the diameter of the through-hole 4228 is larger than the thickness of the projection 4223, the projection 4223 is partially interrupted in the portion where the through-hole 4228 is formed when viewed in the longitudinal direction of the spacer member 422. The spacer member body 4221 has a V-groove shaped notch portion 4228a formed along the longitudinal direction of the spacer member body 4221, which serves as a marker (hole center position) for machining the through-hole 4228.

[0048] The cover member 423 is made of an extruded metal profile such as aluminum and is a component that constitutes the inner frame member of the glass retaining part 4, which is a frame member. The cover member 423 extends from the indoor side surface X2 Gb of the peripheral edge of the glass G to the indoor side steel plate 33b of the door body 3 and outwards from the opening 31, and by covering the entire retaining member body 421, it constitutes the decorative material on the indoor side X2 of the glass retaining part 4.

[0049] As shown in Figure 8, the cover member 423 integrally comprises a cover member body 4231, an inner wall portion 4232, an outer wall portion 4233, and a mounting wall portion 4234. The cover member body 4231 is positioned on the indoor side X2 of the retaining member body 421 and covers the entire indoor side X2 surface of the retaining member body 421. The inner wall portion 4232 has a shape in which the inner end of the cover member body 4231 is bent toward the indoor side X2 of the glass G, and covers the retaining member body 421 from the inside. The outer wall portion 4233 has a shape in which the outer end of the cover member body 4231 is bent toward the steel plate 33b on the indoor side X2 of the door body 30, and covers the retaining member body 421 from the outside. The mounting wall portion 4234 is positioned between the inner wall portion 4232 and the outer wall portion 4233 and protrudes toward the outdoor side X1.

[0050] As shown in Figures 7 and 8, the inner wall portion 4232 has a projection 4232a that abuts against the projection 4214 of the retaining member body 421 from the indoor side X2. The tip of the outer wall portion 4233 integrally has a contact portion 4233a that is bent inward and a claw portion 4233b that is positioned on the indoor side X2 of the contact portion 4233a. As shown in Figure 7, the contact portion 4233a abuts against the steel plate 33b of the door body 30 from the indoor side X2. As shown in Figure 9, the claw portion 4233b engages with an engaging projection 421d integrally formed on the surface of the third hollow portion 4212c of the retaining member body 421 from the indoor side X2. The tip of the mounting wall portion 4234 integrally has a contact portion 4234a that is bent outward and a claw portion 4234b that is positioned on the indoor side X2 of the contact portion 4243a. As shown in Figure 7, the contact portion 4234a abuts against the soft layer portion 4215 of the retaining member body 421 from the indoor side X2. As shown in Figure 9, the claw portion 4234b engages with an engaging projection 421e integrally formed on the surface of the first hollow portion 4212a of the retaining member body 421 from the indoor side X2.

[0051] Next, we will explain how to attach the glass retaining component 4 to the door body 30 to support the periphery of the glass G.

[0052] First, as shown in Figure 8, the outdoor retaining member 41 is attached to the outdoor side X1 of the door body 30. More specifically, the visible plate portion 412 of the outdoor retaining member 41, to which the foamed resin sheet 414 and setting block 415 are attached, is installed from the outdoor side X1 between the glass G and the opening core material 32. The outdoor glass contact portion 411b of the outdoor retaining member 41 abuts against the outdoor side X1 surface Ga of the glass G, supporting the glass G from the outdoor side X1.

[0053] Next, the retaining member body 421 and spacer member 422 of the indoor retaining member 42 are attached to the indoor side X2 of the door body 30. Specifically, the retaining member body 421 and spacer member 422 are assembled in a rectangular shape by the corner piece 5, as shown in Figure 11.

[0054] The corner piece 5 has a corner piece body 51 made of a rectangular block and three pairs of insertion legs 52a to 52c that protrude perpendicularly from the corner piece body 51. The insertion legs 52a and 52b are inserted into the first hollow portion 4212a and the second hollow portion 4212b, respectively, of the retaining member body 421 which extends in the left-right and up-down directions. The insertion legs 52c are inserted into the first hollow portion 422a, respectively, of the spacer member 422 which extends in the left-right and up-down directions. As a result, the upper, lower, and left-right vertical retaining member body 421 and the spacer member 422 are assembled in a rectangular shape with them in contact with each other in the indoor-outdoor direction. The retaining member body 421 and the spacer member 422 are positioned in the correct positions relative to each other by the insertion legs 52a to 52c of the corner piece 5. A foamed resin sheet 424 and a setting block 425 are attached to the inner surface 4221d of the spacer member body 4221.

[0055] The retaining member body 421 and the spacer member 422 are assembled in a rectangular shape, with the spacer member 422 side being inserted from the indoor side X2 between the glass G and the opening core material 32. The protruding portion 4223 of the spacer member 422 is inserted into the screw fixing groove portion 412d of the outdoor retaining member 41. As a result, the rectangularly assembled retaining member body 421 and spacer member 422 are positioned in the correct position relative to the outdoor retaining member 41.

[0056] Next, the fixing screw 43 is inserted from the indoor side X2. The fixing screw 43 is screwed into the screw fixing groove 412d of the outdoor side retaining member 41 through the through hole 4219 of the retaining member body 421 and the through hole 4228 of the spacer member 422. As a result, the retaining member body 421 and the spacer member 422 are integrally fixed to the outdoor side retaining member 41. The indoor side glass contact portion 4213 of the retaining member body 421 abuts against the indoor side X2 surface Gb of the glass G, supporting the glass G from the indoor side X2. The outdoor side surface 4211a of the second hollow portion 4212b of the retaining member body 421 is in close contact with the protruding base portion 4226 of the spacer member 422, and the two soft protrusions 4216, 4216 of the retaining member body 421 are in close contact with the indoor end surface 4221b of the spacer member body 4221 and deform, thereby maintaining a watertight seal between the retaining member body 421 and the spacer member 422. The two soft protrusions 4224, 4224 of the spacer member 422 are in close contact with the indoor end surface 412f and the protruding piece 412e of the visible plate portion 412 of the outdoor retaining member 41 and deform, thereby maintaining a watertight seal between the outdoor retaining member 41 and the spacer member 422.

[0057] Subsequently, the cover member 423 is engaged with and attached to the retaining member body 421 from the indoor side X2. As a result, as shown in Figure 1, the peripheral edge of the outdoor side X1 of the glass G is covered all four sides by the decorative plate portion 411 of the outdoor retaining member 41, and the peripheral edge of the indoor side X2 of the glass G is covered all four sides by the cover member 423 of the indoor retaining member 42.

[0058] Thus, even if the thickness of the glass G or the door body 30 increases due to the glass G having three glass plates G1 to G3, the increase in thickness can be compensated for by adding spacer members 422. There is no need to newly manufacture glass retaining parts for each thickness of the glass G or the door body 30, and the outdoor retaining member 41, retaining member body 421, and cover member 423 other than the spacer member 422 can be used in common with conventional parts.

[0059] Figure 12 shows a glass retaining component 4A having a spacer member 422A in another embodiment. Parts with the same reference numerals as those in Figure 7 indicate parts with the same configuration, so their descriptions are based on the above description and may be omitted in the following description.

[0060] The glass retaining component 4A shown in Figure 12 differs from the glass retaining component 4 shown in Figure 7 in the configuration of the spacer member 422A. The spacer member 422A has a larger thickness in the visible direction compared to the spacer member 422 shown in Figure 7. The first hollow portion 422a and the second hollow portion 422b of the spacer member 422A are formed to extend in the visible direction compared to the spacer member 422 shown in Figure 7.

[0061] The spacer member 422A directly supports the glass G by contacting the end face Gc of the glass G with its inner surface 4221d. With this glass retaining component 4A, the spacer member 422A can also serve as a setting block, thus eliminating the need for a setting block to be placed in the area of ​​the spacer member 422A.

[0062] Figure 13 shows another embodiment of the spacer member 422B. Parts with the same reference numerals as those in Figure 10 indicate parts with the same configuration; therefore, their descriptions are based on the above description and may be omitted in the following description.

[0063] The spacer member 422B shown in Figure 13 does not have the protrusion 4223 that is provided on the spacer member 422 shown in Figure 10. The glass retaining component using this spacer member 422B also has the same effect as the glass retaining component 4 shown in Figure 7, but because the protrusion 4223 is not provided, the positioning effect of the indoor retaining component 42 is superior in the indoor retaining component 42 which has the spacer member 422 which has the protrusion 4223. The protrusion 4223 of the spacer member 422A shown in Figure 12 does not necessarily have to be provided, just like the spacer member 422B.

[0064] Figure 14 shows another embodiment of the spacer member 422C. Parts with the same reference numerals as those in Figure 10 have the same configuration, so their descriptions are based on the above description and may be omitted in the following description.

[0065] In the spacer member 422C shown in Figure 14, the projection 422a1 provided on the inner surface of the first hollow portion 422a is formed in a semicircular cross-section. This ensures that the shape of the projection 422a1 is stable when the spacer member 422C is extruded. Furthermore, in the spacer member 422C, the projection 4227 on the outer surface 4221c is formed in a trapezoidal shape with slopes on the outdoor side X1 and the indoor side X2, respectively. That is, the outdoor side X1 and the indoor side X2 surfaces of the projection 4227 are formed by inclined surfaces 4227a, 4227a, respectively. This allows the projection 4227 to easily overcome steps and other obstacles when inserting the spacer member 422C between the glass G and the opening core material 32 from the indoor side X2, thus preventing the projection 4227 from getting caught and allowing for smooth insertion. The inclined surface 4227a only needs to be formed on the outdoor side X1 surface of the projection 4227.

[0066] Figures 15 to 17 show a door / window 1A according to another embodiment. This door / window 1A differs from the door / window 1 described above in that it has a frame 2A with further improved thermal insulation performance. In the frame 2 of door / window 1A shown in Figures 15 to 17, parts with the same reference numerals as the frame 2 in door / window 1 indicate parts with the same function and configuration. Therefore, their explanations may be omitted below, drawing on the explanation of the frame 2 in door / window 1.

[0067] The upper frame 21 of the frame body 2A shown in Figure 15 is formed in a rectangular cross-section and has an upper wall portion 21a, a lower wall portion 21b, an exterior wall portion 21c, and an interior wall portion 21d. The second mounting piece 21g, an exterior projection piece 21h, and an interior projection piece 21i are integrated with the interior side X2 of the exterior upper frame portion 211, which has a hollow portion 21e inside, via a bridge portion 212. The exterior upper frame portion 211, the second mounting piece 21g, the exterior projection piece 21h, and the interior projection piece 21i are all made of extruded metal profiles such as aluminum. The bridge portion 212 is made of a heat-insulating material such as resin. Therefore, this upper frame 21 has excellent heat insulation properties.

[0068] The second mounting piece 21g has a connecting projection piece 21g2. The connecting projection piece 21g2 is positioned parallel to the outer projection piece 21h on the outdoor side X1 of the outer projection piece 21h and protrudes outward with the same projection height as the outer projection piece 21h. The connecting projection piece 21g2 is positioned further outward X1 than the inner projection piece 21i. The bridge portion 212 is provided across the lower end of the indoor wall portion 21d on the outdoor upper frame portion 211 and the connecting projection piece 21g2, and connects the two together as a single unit.

[0069] On the underside of the bridge section 212, a resin shielding plate 213 is provided along the length of the upper frame 21 so as to cover the bridge section 212. The shielding plate 213 is attached to the bridge section 212 by screws 214 that are screwed into the bridge section 212 through the shielding plate 213. The upper frame side airtight material 210 is positioned so as to cover the shielding plate 213 from below.

[0070] An L-shaped angle portion 21j is positioned on the indoor side X2 of the second mounting piece 21g. That is, instead of the integrally molded angle portion 21g1 shown in Figure 3, an angle portion 21j, which is separate from the second mounting piece 21g, is attached to the outer protruding piece 21h by rivets 21j1 on the indoor side X2 of the second mounting piece 21g. Since the angle portion 21j is provided separately from the second mounting piece 21g, it can be formed from resin.

[0071] The left and right vertical frames 23 and 24 of the frame 2A shown in Figures 16 and 17 are formed in a rectangular cross-section having outer wall portions 23a and 24a, inner wall portions 23b and 24b, outdoor wall portions 23c and 24c, and indoor wall portions 23d and 24d. The outdoor vertical frame portions 231 and 241, which have hollow portions 23e and 24e inside, have the second mounting pieces 23g and 24g, outer protruding pieces 23h and 24h, and inner protruding pieces 23i and 24i integrated onto the indoor side X2 via bridge portions 232 and 242. The outdoor vertical frame portions 231 and 241, the second mounting pieces 23g and 24g, the outer protruding pieces 23h and 24h, and inner protruding pieces 23i and 24i are all made of extruded metal profiles such as aluminum. The bridge portions 232 and 242 are made of a heat insulating material such as resin. Therefore, the vertical frames 23 and 24 of this structure have excellent heat insulation properties.

[0072] The second mounting pieces 23g, 24g have connecting protrusions 23g2, 24g2. The connecting protrusions 23g2, 24g2 are positioned parallel to the outer protrusions 23h, 24h on the outdoor side X1 of the outer protrusions 23h, 24h, and protrude outward with the same protrusion height as the outer protrusions 23h, 24h. The connecting protrusions 23g2, 24g2 are positioned further outward X1 than the inner protrusions 23i, 24i. The bridge pieces 232, 242 are provided extending from the inner ends of the indoor wall pieces 23d, 24d in the outdoor vertical frame pieces 231, 241 to the connecting protrusions 23g2, 24g2, and connect the two together.

[0073] On the inner surface of the bridge sections 232 and 242, resin shielding plates 233 and 243 are provided along the length of the vertical frames 23 and 24, so as to cover the bridge sections 232 and 242. The shielding plates 233 and 243 are attached to the bridge sections 232 and 242 by screws 234 and 244 that penetrate the shielding plates 233 and 243 and are screwed into the bridge sections 232 and 242. The vertical frame side airtight materials 230 and 240 are positioned so as to cover the shielding plates 233 and 243 from below.

[0074] On the indoor side X2 of the second mounting pieces 23g and 24g, L-shaped angle pieces 23j and 24j are positioned. That is, on the indoor side X2 of the second mounting pieces 23g and 24g, instead of the integrally molded angle pieces 23g1 and 24g1 shown in Figure 4, angle pieces 23j and 24j, which are separate from the second mounting pieces 23g and 24g, are attached to the outer protruding pieces 23h and 24h by rivets 23j1 and 24j1. Since the angle pieces 23j and 24j are provided separately from the second mounting pieces 23g and 24g, they can be formed from resin.

[0075] Figures 18 to 20 show the thermal insulation structure in the opening 31 of the door body 30, respectively. In Figures 18 to 20, parts with the same reference numerals as in Figure 7 indicate parts with the same function and configuration; therefore, their explanations refer to the explanations in Figure 7 above and may be omitted below.

[0076] The opening core material 32 of the door body 30 shown in Figure 18 is the same as the opening core material 32 shown in Figure 7 in that it is composed of a resin core material 321 and a metal core material 322. However, the width of the metal core material 322 in the depth direction is smaller than the width of the resin core material 321 in the depth direction, and it is positioned off-center towards the exterior side X1 on the outer periphery side of the resin core material 321. As a result, a space is formed between the metal core material 322 and the resin core material 321 on the interior side X2, and the resin block 323 is housed in this space.

[0077] In the example shown in Figure 18, the position of the indoor end X2 of the metal core material 322 in the indoor-outdoor direction is approximately the same as the position of the glass plate G3 on the indoor side X2 of the glass G. The resin block 323 fills the space between the indoor end X2 of the metal core material 322 and the part. The metal core material 322 and the resin block 323 in this opening core material 32 are provided on the outer surface of the resin core material 321 along the left-right direction of the upper part of the opening 31, the left-right direction of the lower part, and the up-down direction of the vertical part. As a result, the transfer of heat in the indoor-outdoor direction through the metal core material 322 is further suppressed, and the thermal insulation performance of the opening 31 of the door body 30 is further improved.

[0078] Figure 19 shows a case where the width of the metal core material 322 in the depth direction is made even smaller than that of the metal core material 322 shown in Figure 18. Specifically, on the indoor side X2 of the metal core material 322, a space approximately twice the size of that in Figure 18 is formed between it and the resin core material 321, and two resin blocks 323 are housed side by side in the depth direction within this space. The metal core material 322 and resin blocks 323 in this opening core material 32 are provided around all four sides of the opening 31. As a result, the transfer of heat from the inside to the outside through the metal core material 322 is further suppressed than in the case of Figure 18, and the thermal insulation of the opening 31 of the door body 30 is further improved.

[0079] As shown in Figure 19, if multiple resin blocks 323 are provided, at least one resin block 323 may be housed between the outdoor end X1 of the metal core material 322 and the outdoor end X1 of the resin core material 321.

[0080] The resin core material of the opening core material 32 of the door body 30 shown in Figure 20 is composed of two resin core materials 321a and 321b, which are divided into an outdoor side X1 and an indoor side X2. The resin core materials 321a and 321b are each formed in an L-shape in cross-section. The resin core material 321a covers the corner of the outdoor side X1 of the metal core material 322 and extends outward to cover the end face of the outdoor side X1 of the metal core material 322. The resin core material 321b covers the corner of the indoor side X2 of the metal core material 322 and extends outward to cover the end face of the indoor side X2 of the metal core material 322. Between the two resin core materials 321a and 321b, an exposed portion 32a1 is formed where the metal core material 322 is exposed due to the absence of a resin core material.

[0081] According to the structure of the opening core material 32 shown in Figure 20, since the resin core material is divided into two resin core materials 321a and 321b, even if the thickness of the door body 30 differs due to, for example, a difference in the number of glass plates constituting the glass G, the resin core materials 321a and 321b can be used in common.

[0082] The above embodiment provides the following effects. The glass retaining parts 4, 4A have an outdoor retaining member 41 positioned on the outdoor side X1 of the peripheral edge of the glass G that is fitted into the opening 31 of the door body 30, and an indoor retaining member 42 positioned on the indoor side X2 of the peripheral edge of the glass G, and the outdoor retaining member 41 and the indoor retaining member 42 are fixed with screws from the indoor side X2 to clamp the peripheral edge of the glass G, and the indoor retaining member 42 has a retaining member body 421 that supports the peripheral edge of the glass G from the indoor side X2, and spacer members 422, 422A, 422B positioned between the retaining member body 421 and the outdoor retaining member 41. According to this, regardless of the thickness of the glass G or the door body 30, there is no need to newly manufacture the glass retaining parts 4 and 4A, and the outdoor retaining member 41, retaining member body 421, and cover member 423, other than the spacer members 422, 422A, and 422B, can be used in common with conventional members.

[0083] In the above embodiment, the outdoor side retaining member 41 has a screw fixing groove portion 412d at the end of the indoor side X2 that opens toward the indoor side X2, and the spacer members 422 and 422A have a projection portion 4223 at the end of the outdoor side X1 that is inserted into the screw fixing groove portion 412d. With this, the indoor side retaining member 42 can be easily positioned in the correct position relative to the outdoor side retaining member 41.

[0084] In the above embodiments, the spacer members 422, 422A, and 422B have hollow portions (first hollow portion 422a and second hollow portion 422b). This provides excellent strength and heat insulation in the spacer members 422, 422A, and 422B.

[0085] In the above embodiment, the spacer members 422, 422A, and 422B have a soft projection 4224 on the outdoor end face 4221a that abuts against the outdoor retaining member 41. This ensures a watertight seal between the outdoor retaining member 41 and the spacer members 422, 422A, and 422B.

[0086] In the above embodiments, the spacer members 422, 422A, and 422B have projections 4227 on the surface opposite to the surface facing the glass G (outer surface 4221c). This makes it easy to distinguish between the inner surface 4221d and the outer surface 4221c of the spacer members 422, 422A, and 422B based on the presence or absence of the projections 4227.

[0087] In the above embodiments, the spacer members 422, 422A, and 422B have notches 4228a for machining through holes for screw insertion. This allows the through holes 4228 to be easily formed at a predetermined position aligned with the through holes 4219 of the retaining member body 421.

[0088] In the above embodiment, the spacer members 422, 422A, and 422B have a water-repellent portion 4225 at the end on the indoor side X2. This prevents water that has entered between the glass G and the spacer members 422, 422A, and 422B from the outdoor side X1 from flowing into the retaining member body 421 on the indoor side X2.

[0089] In the above embodiments, the spacer members 422, 422A, and 422B are made of resin or metal. This allows the spacer members 422, 422A, and 422B to be easily and inexpensively manufactured by extrusion molding. In particular, when the spacer members 422, 422A, and 422B are made of metal, they can maintain their support function for the glass G even in the event of a fire.

[0090] In the above embodiment, the spacer member 422A also serves as a setting block. This eliminates the need for a setting block to support the glass G, thus reducing the number of parts and improving the ease of assembly of the door body 3.

[0091] In the above embodiment, the retaining member body 421 has a metal core material 421b inside the resin member 421a. This improves the strength of the retaining member body 421, allowing the peripheral edge of the glass G to be stably supported from the indoor side X2, and also providing a function to prevent the glass G from falling out in the event of a fire.

[0092] In the above embodiment, the door body 3 comprises a door body 30 having an opening 31, a glass G fitted into the opening 31, and the glass retaining parts 4 and 4A that clamp the peripheral edge of the glass G. With this configuration, the door body 3 can achieve the effects exhibited by the glass retaining parts 4 and 4A.

[0093] In the above embodiment, the joinery 1 comprises a frame 2 provided in the structural opening 101, and the above-mentioned door body 3 housed inside the frame 2 so as to be able to open and close the structural opening 101. With this configuration, the joinery 1 can achieve the effects exhibited by the above-mentioned glass retaining parts 4, 4A.
