By the way, in many cases, a lock case is attached as an accessory to the prospective surface of the door body at a position substantially intermediate in the height direction. The lock case includes a thin rectangular parallelepiped case body and a flange provided on one side surface of the case body. In this lock case, the case body is housed inside the door body through an insertion opening formed in the edge material, and is held by the door body by screwing a mounting screw into the aggregate via a flange.

Here, when the edge material having the insertion opening formed is attached to the aggregate, the mounting screw is screwed into the portion close to the insertion opening so that the peripheral edge of the insertion opening does not float from the edge material. Is preferable. However, in the case of a door body in which mounting screws are screwed to the peripheral edge of the insertion opening, the mounting screws of the edge material and the mounting screws of the lock case are concentrated and exposed at a position where it is easy to see, and the appearance quality is improved. It is not always preferable in that respect.

The above problem is not unique to the lock case. For example, at the hanging source of the door body, since the electric lock is wired to the frame side, an accessory part called an energizing case may be attached. Like the lock case, the energizing case is provided with a flange. Also in this energizing case, a flange is arranged inside the insertion opening formed in the edge material, and the mounting screw is screwed into the aggregate via the flange to hold the door body. Therefore, the mounting screws of the edge material and the mounting screws of the energizing case are concentrated, which may cause the same problem as the door end of the door body, which impairs the appearance quality.

In view of the above circumstances, it is an object of the present invention to provide a door body and fittings to which an edge material can be reliably attached without impairing the appearance quality.

In order to achieve the above object, the door body according to the present invention is a door in which the finding surface of the aggregate having a four-circumferential framework is covered with a surface material, and an edge material is arranged on the prospective surface of the aggregate extending in the vertical direction. The aggregate and the edge material are engaging means that engage with each other by relatively moving the aggregate and the edge material and prevent the edge material from moving in the separation direction with respect to the aggregate. When the engaging means is engaged, the edge material faces the protruding portion provided on the aggregate, and the aggregate and the engaging means are released in the disengaging direction. It is characterized in that a contact piece that limits the relative movement of the edge material is provided .

According to the present invention, the edge material can be temporarily fixed to the aggregate by contacting the contact piece with the protruding portion of the edge material, and the work when attaching the edge material can be facilitated. Become.

Further, according to the present invention, in the above-mentioned door body, the aggregate has a resin bone portion in which each found surface is covered with a surface material and the edge material is attached to an outer prospective surface, and the resin bone portion. It is configured to include a metal bone portion disposed on a portion opposite to the edge material sandwiched between the edge material, and the edge material includes a metal edge material and a resin edge material, and the metal edge material is provided. The resin edge material is arranged side by side in the prospective direction to cover the prospective surface of the aggregate, and the engaging means is provided between the metal edge material and the resin bone portion. To do.

Further, the finding direction is a direction along the top and bottom orthogonal to the prospective direction in the case of a member along the horizontal such as the aggregate 11 arranged along the upper edge and the lower edge of the door body 13. In the case of a member along the top and bottom such as the aggregate 11 arranged along both side edges of the 13, the direction is along the horizontal direction orthogonal to the prospective direction. A plane along the finding direction may be referred to as a finding surface.

As shown in FIG. 5, the contact portions 11A2 and 11A3 of the resin bone portion 11A form a plate-like portion that is bent at a substantially right angle from both side edges of the resin base portion 11A1 in the same direction and extends. There is. The partition wall portion 11A4 is a plate-shaped portion protruding from a portion between the two contact portions 11A2 and 11A3 so as to face the contact portions 11A2 and 11A3. The position where the partition wall portion 11A4 is provided is a position deviated from the center between the two contact portions 11A2 and 11A3 toward the room side. In the present embodiment, the partition wall portion 11A4 is provided at a position where the distances to the contact portions 11A2 and 11A3 are approximately 3: 2. In the following, for convenience, when distinguishing between the two contact portions 11A2 and 11A3, the one having a large distance to the partition wall portion 11A4 is referred to as the first contact portion 11A2, and the one having a small distance to the partition wall portion 11A4 is referred to as the second contact portion. It will be referred to as the contact portion 11A3.

The contact portions 11A2 and 11A3 and the partition wall portion 11A4 are provided with ridge portions 11A5 over the entire length of the extending end portions thereof. The ridges 11A5 of the contact portions 11A2 and 11A3 are provided so as to project from one surface facing the partition wall 11A4, and the ridges 11A5 of the partition wall 11A4 face the contact portions 11A2 and 11A3. It is provided so as to protrude from both surfaces. Further, the first contact portion 11A2 is provided with a support protrusion portion 11A6 on a surface facing the partition wall portion 11A4. The support protrusion 11A6 is a plurality of protruding portions extending along the length of the resin bone portion 11A. In the present embodiment, two support protrusions 11A6 are provided on the first contact portion 11A2. The protrusion heights of the support protrusions 11A6 are set to be equal to each other and smaller than the protrusion heights of the protrusions 11A5.

As shown in FIGS. 6 to 12, the aggregate 11 extending vertically along the door main body 13 has a position between the first contact portion 11A2 and the partition wall portion 11A4 at a position substantially central in the vertical direction. The accommodating opening 14 is provided at this position, and the resin bone portion 11A is provided with two engaging receiving portions 11A7 and 11A8. The accommodating opening 14 is for inserting the case body 31 of the accessory part 30 described later, and is formed in a vertically long substantially rectangular shape along the length of the aggregate 11. Screw holes 15 for screwing the flange 32 of the accessory 30 are formed on both sides of the accommodation opening 14 in the aggregate 11.

As shown in FIGS. 4 and 5, the engagement receiving portions 11A7 and 11A8 project from the resin base portion 11A1 at a substantially right angle in a direction opposite to the projecting direction of the first contact portion 11A2, and then face the outdoor side. It has a bent hook-shaped cross-sectional shape. As is clear from FIG. 5, the surfaces 11A7a and 11A8a facing the resin base 11A1 at the bent portions of the engagement receiving portions 11A7 and 11A8 are inclined toward the tip so as to be gradually separated from the resin base 11A1 to form a resin. The gap with the base 11A1 is increasing. One engaging receiving portion 11A7 is provided at a position between the first contact portion 11A2 and the partition wall portion 11A4, and the other engaging receiving portion 11A8 is provided between the partition wall portion 11A4 and the second contact portion 11A3. It is provided at a position close to the partition wall portion 11A4 between the two. In the following, when distinguishing between the two engaging receiving portions 11A7 and 11A8, the one close to the first contact portion 11A2 is referred to as the first engaging receiving portion 11A7, and the one close to the partition wall portion 11A4 is referred to as the second engaging portion. It will be referred to as the receiving unit 11A8.

The metal bone portion 11B is formed by integrally molding a metal base portion 11B1 and two side wall portions 11B2 and 11B3. The metal base portion 11B1 and the side wall portions 11B2 and 11B3 each have a flat plate shape, and the side wall portions 11B2 and 11B3 are bent at substantially right angles from both side edges of the metal base portion 11B1 toward the same direction. As is clear from the figure, the metal bone portion 11B is arranged in the space between the first contact portion 11A2 and the partition wall portion 11A4 in the resin bone portion 11A, and the metal base portion 11B1 is brought into contact with the resin base portion 11A1. In this case, one side wall portion 11B2 abuts on the first contact portion 11A2 via the support protrusion 11A6, the other side wall portion 11B3 abuts on the partition wall portion 11A4, and the extending end faces of the side wall portions 11B2 and 11B3. The ridges 11A5 of the first contact portion 11A2 and the ridges 11A5 of the partition wall 11A4 are formed to face each other.

When the metal bone portion 11B is arranged in the space between the first contact portion 11A2 and the partition wall portion 11A4, if the metal base portion 11B1 is pushed between the first contact portion 11A2 and the partition wall portion 11A4, the first hit Since the contact portion 11A2 and the partition wall portion 11A4 are elastically deformed so as to expand each other, this can be easily performed. When the metal base portion 11B1 comes into contact with the resin base portion 11A1, the extending end faces of the side wall portions 11B2 and 11B3 face the ridge portion 11A5 as described above, so that between the first contact portion 11A2 and the partition wall portion 11A4. There is no possibility that the metal bone portion 11B will easily fall out of the space. Reference numeral 11B4 in FIG. 3 is a connecting piece provided on the metal bone portion 11B arranged on the upper edge and the lower edge of the door body 13. The connecting piece 11B4 is for connecting to the metal bone portions 11B arranged on both side edges of the door body 13, and is bent at substantially right angles from both ends of the metal base portion 11B1 toward the same direction as the side wall portions 11B2 and 11B3. ing.

As is clear from FIGS. 3 and 4, in the present embodiment, the heat insulating material 16 is arranged in the space between the partition wall portion 11A4 and the second contact portion 11A3 in the resin bone portion 11A. The heat insulating material 16 has a rectangular parallelepiped shape formed of a material having a thermal conductivity lower than that of air. In particular, if a flame-retardant material is applied as the material of the heat insulating material 16, it can contribute to fire resistance in the event of a fire. The heat insulating material 16 has a width slightly larger than the mutual distance between the partition wall portion 11A4 and the second contact portion 11A3, and is compressed into the space between the partition wall portion 11A4 and the second contact portion 11A3. It is arranged in the state of being. As described above, since the ridge portion 11A5 is provided on the partition wall portion 11A4 and the second contact portion 11A3, the heat insulating material 16 easily falls off from the space between the partition wall portion 11A4 and the second contact portion 11A3. There is no fear.

The aggregate 11 having the above-described configuration constitutes the outer shell of the door body 13 by forming a four-circumferential framework with the metal bone portions 11B all oriented in the same direction. Although not clearly shown in the figure, the metal bone portions 11B may be riveted to each other via the connecting piece 11B4. The resin bone portions 11A do not necessarily have to be connected, but they may be joined to each other by heat welding.

The surface material 12 is formed by a thin plate-shaped member formed of a metal such as a steel material, and has a substrate portion 12a and a bent portion 12b. The substrate portion 12a is a portion having a rectangular shape having substantially the same size as the external dimensions of the door body 13. The bent portion 12b is a portion that is bent at a substantially right angle from the four circumferences of the substrate portion 12a in the same direction. The extending dimension of the bent portion 12b is set to about 1/5 of the dimension along the prospective direction of the resin base portion 11A1 described above.

The surface material 12 having the above-described configuration covers the finding surface 11a of the aggregate 11 having a four-circumferential framework, and is arranged so that each of the bent portions 12b partially covers the prospective surface 11A1a of the resin base portion 11A1. The door body 13 is formed by joining the aggregate 11 and the door body 13. As a method of joining the bent portion 12b of the surface material 12 and the aggregate 11, for example, a rivet 17 may be applied. For the portion where the resin bone portion 11A and the metal bone portion 11B are overlapped with each other, it is preferable to join the bent portion 12b of the surface material 12 to the metal bone portion 11B via the resin bone portion 11A.

For the portion of the aggregate 11 in which the metal bone portion 11B does not exist, it is sufficient to join the bent portion 12b of the surface material 12 to the resin bone portion 11A. However, as shown in the modified example 1 of FIG. 13A and FIG. 13B, the metal bone portion 11B'has an extension portion 11B5 that partially extends beyond the partition wall portion 11A4. May be applied so that the bent portion 12b of the other surface material 12 is also joined to the extension portion 11B5 via the resin bone portion 11A. The extension portion 11B5 does not necessarily have to be integrally molded with the metal bone portion 11B, and as in the modified example 2 shown in FIG. 14, the extension portion 11B5'forming a separately molded flat plate is formed as a metal base. The same effect can be obtained even if the metal bone portion 11B ″ is formed by joining the 11B1.

It is preferable to interpose a heat insulating layer material 18 such as urethane foam between the surface materials 12. When the heat insulating layer material 18 is provided between the surface materials 12, an adhesive material may be applied between the surface materials 12 to pressurize the material. Here, the side wall portion 11B2 of the metal bone portion 11B is in contact with the first contact portion 11A2 of the resin bone portion 11A. Therefore, when the surface material 12 is placed on the finding surface 18a of the aggregate 11 and the heat insulating layer material 18 and pressed in the prospective direction, the first contact portion 11A2 maintains the position while the heat insulating layer. The material 18 will bend, which may affect the appearance quality of the surface material 12. In order to prevent this, the support protrusion 11A6 provided on the first contact portion 11A2 of the resin bone portion 11A may be molded with a soft resin. That is, if the aggregate 11 formed by molding the support protrusion 11A6 with a soft resin is applied, the support protrusion 11A6 is appropriately deformed (crushed) when pressed. Therefore, when the pressure is applied, the first contact portion 11A2 can be deformed, and there is no possibility of affecting the appearance quality of the surface material 12. The resin bone portion 11A having a portion molded by a hard resin and a portion molded by a soft resin can be easily integrally molded by applying a double mold (two-color molding). If the method of pressurizing the door body 13 is not applied, it is not always necessary to mold the support protrusion 11A6 with a soft resin.

As shown in FIG. 2, the door body 13 configured as described above is provided with the edge member 20 and the accessory 30 attached to the prospective surface 11A1a of the aggregate 11 extending along the top and bottom, respectively. The edge material 20 covers the prospective surface of the door body 13 (the prospective surface 11A1a of the aggregate 11 and the bent portion 12b of the surface material 12), and is extruded by a metal such as an aluminum alloy as shown in FIGS. 15 and 16. It includes a molded metal edge material 20A and a resin edge material 20B extruded with a hard resin such as hard PVC. Although the detailed configuration of the edge material 20 attached to the prospective surface of the door body 13 and the edge material 20 attached to the prospective surface of the door body 13 are different, the basic configuration is the same. Therefore, in the following, the basic configuration will be described using the edge material 20 for the door end shown in FIGS. 15 and 16 as a typical example.

The metal edge material 20A is a portion arranged on the outdoor side, and is formed by integrally molding the cover base portion 20A1 and the two engaging hook portions 20A2 and 20A3.

Is. That is, as described above, the base portion 21a arranged in the accommodating portion 20A6 is prevented from moving relative to the edge member 20 along the longitudinal direction by the positioning portion 21a2, and is elastically engaged with the tip portion 21a1 of the base portion 21a. The piece 21a3 prevents the relative movement of the edge member 20 in the direction orthogonal to the longitudinal direction and the relative movement in the direction away from the cover base 20A1.

The sandwiched piece portion 21b is a thin plate-like portion extending from both sides of the base portion 21a, and as shown in FIG. 9, when the base portion 21a is brought into contact with the cover base portion 20A1 of the edge material 20, the cover base portion 20A1 It is configured to secure a gap d between the two. Screw insertion holes 21b1 are formed at the extending ends of the sandwiched piece portion 21b, respectively.

In the present embodiment, as shown in FIG. 7, notches 20A6c are provided on both sides of the insertion opening 20A5 in the hooking portion 20A6b of the edge member 20. When the positioning portions 21a2 of the sandwiched member 21 are arranged in each of the notches 20A6c, as shown in FIGS. 11 and 12, the sandwiched piece portions 21b protrude from both sides of the insertion opening 20A5 and are sandwiched. The screw insertion hole 21b1 of the piece 21b is provided so as to match the screw hole 15 of the aggregate 11. The length of the sandwiched piece portion 21b is set so that a distance equivalent to the longitudinal dimension of the accommodating opening 14 provided in the aggregate 11 is secured between the edges of each other.

In the present embodiment, since the base portion 21a is provided with the two sandwiched piece portions 21b to form the sandwiched member 21, the same parts can be attached to both ends of the insertion opening 20A5. It is possible to reduce the manufacturing cost. However, the present invention is not necessarily limited to this, and the sandwiched member 21 may be configured as a dedicated component in which one sandwiched piece portion 21b is provided on the base portion 21a. Further, since the sandwiched member 21 is formed separately from the edge member 20, the manufacturing operation of the edge member 20 is not complicated even when the sandwiched member 21 is formed into an arbitrary shape. However, although not shown in the drawing, the sandwiched member 21 may be integrally formed with the edge member 20.

As shown in FIG. 2, the accessory part 30 is required when the door body 10 is used as a fitting, such as a lock case provided at the door end or an energizing case provided at the hanging source. The lock case and the energizing case have different uses, but they have the same basic configuration. Therefore, in the following, the basic configuration of the accessory part 30 will be described with a lock case attached to the door body 13 via the edge material 20 for the door end as a typical example.

As shown in FIGS. 7 to 12, the accessory part 30 includes a thin rectangular parallelepiped case main body 31 and a flange 32 provided on one side surface of the case main body 31. The main body case is accommodated inside the door main body 13 through the accommodating opening 14 formed in the aggregate 11. The flange 32 has a rectangular plate shape having external dimensions that can be fitted into the insertion opening 20A5 formed in the edge member 20. The plate thickness t of the flange 32 is formed to have a size slightly larger than the gap d secured from the surface of the sandwiched piece portion 21b to the surface of the cover base portion 20A1 of the edge material 20. Screw insertion holes 32a are provided in the portions of the flange 32 corresponding to the screw holes 15 of the aggregate 11.

The accessory 30 having the above configuration is attached to the prospective surface of the door body 13 together with the edge member 20. That is, first, as shown in FIG. 19, the metal edge material 20A and the resin edge material 20B are engaged with each other, and the sandwiched members 21 are attached to both side portions of the insertion opening 20A5 to form the edge material 20. While pressing the edge member 20 against the prospective surface of the door body 13, as shown in FIG. 16, the two engaging hook portions 20A2 and 20A3 are engaged with the engaging receiving portions 11A7 and 11A8 of the aggregate 11, respectively.

In this state, since the engaging hook portions 20A2 and 20A3 are engaged with the engaging receiving portions 11A7 and 11A8 of the aggregate 11, the movement of the edge member 20 in the separating direction with respect to the aggregate 11 is prevented. At the same time, the movement of the edge material 20 toward the indoor side with respect to the resin base portion 11A1 is prevented. Further, since the tip of the contact piece 20B3 provided on the resin edge material 20B is arranged to face the second engagement receiving portion 11A8, the edge material 20 can move toward the outdoor side with respect to the resin base portion 11A1. It will be restricted. Therefore, the edge material 20 can be temporarily fixed to the prospective surface of the door body 13 without falling off. Moreover, in the present embodiment, since the contact piece 20B3 is provided on the resin edge material 20B, the contact piece 20B3 can be easily deformed as compared with the case where the contact piece 20B3 is provided on the metal edge material 20A. Therefore, the gap between the second engaging receiving portion 11A8 and the second engaging receiving portion 11A8 can be set to be small in advance, and it is possible to prevent the edge material 20 from rattling even in the temporarily fixed state.

Next, as shown in FIGS. 8 and 10, the case body 31 of the accessory 30 is housed inside the door body 13 through the insertion opening 20A5 of the edge material 20 and the storage opening 14 of the aggregate 11, and the flange 32. Is arranged in the insertion opening 20A5 of the edge material 20. Further, if the mounting screw S is screwed into the screw hole 15 of the aggregate 11 via the screw insertion hole 32a of the flange 32 and the screw insertion hole 21b1 of the sandwiched member 21 attached to the edge material 20, the accessory part 30 can be obtained. It can be attached to the door body 13. As described above, according to the door body 10, since the edge material 20 is temporarily fixed to the door body 13, it is necessary to hold down the edge material 20 when screwing the mounting screw S. It is possible to facilitate the work.

In the state where the mounting screw S is screwed, the sandwiched member 21 is sandwiched between the aggregate 11 and the flange 32, and the edge member 20 moves relative to the aggregate 11 via the sandwiched member 21. Since it is blocked, the edge material 20 can be held on the prospective surface of the door body 13. Although not clearly shown in the figure, if the edge material 20 is temporarily fixed to the prospective surface at the hanging source of the door body 13 and then the energizing case is attached to the door body 13 by the same procedure, the edge material 20 is simultaneously attached. It can be held on the prospective surface of the door body 13.

According to the door body 10 in which the accessory part 30 is attached to the prospective surface of the door body 13 as described above, the peripheral edge of the insertion opening 20A5 provided in the edge material 20 by the mounting screw S for attaching the accessory part 30. Since the parts are securely tightened together, a separate mounting screw for mounting the peripheral surface of the insertion opening 20A5 is not required, and the appearance quality is impaired by reducing the number of mounting screws S exposed to the outside. Can be prevented.

Moreover, as the aggregate 11 of the door body 13, since the metal bone portion 11B is arranged between the first contact portion 11A2 and the partition wall portion 11A4 in the resin base portion 11A1, the partition wall is formed from the second contact portion 11A3. The metal bone portion 11B and the surface material 12 can be arranged apart from each other by a distance secured between the portions 11A4, and the door body 13 alone can improve the heat insulating property. Further, in the embodiment, since the heat insulating material 16 having a thermal conductivity smaller than that of air is arranged in the space between the second contact portion 11A3 and the partition wall portion 11A4, the heat insulating property of the door body 13 is increased. Can be further improved. However, it is not always necessary to dispose the heat insulating material 16 in the space between the second contact portion 11A3 and the partition wall portion 11A4. Further, as the edge material 20, a metal edge material 20A formed of metal and a resin edge material 20B formed of resin arranged side by side in the prospective direction are applied, so that the edge material 20 becomes a thermal bridge. However, it contributes to the improvement of the heat insulating property of the door body 10.

As shown in FIGS. 1 and 2, the frame body 40 that supports the door body 10 is configured by framing the upper frame 41, the lower frame 42, and the left and right vertical frames 43 in four directions. Of these, the lower frame 42 is formed by arranging two lower frame elements 42a and 42b formed of a metal such as an aluminum alloy side by side in a prospective direction and connecting them with a connecting material 42c. The connecting material 42c is formed of a resin having heat insulating properties.

A lumber 44 is provided below the lower frame 42. The width timber 44 covers the finding surface on the outdoor side between the lower frame 42 and the foundation B. Similar to the lower frame 42, the skirting board 44 of the present embodiment has two skirting boards elements 44a and 44b formed of a metal such as an aluminum alloy arranged side by side in a prospective direction, and is made of heat insulating resin between them. It is connected by a connecting member 44c. The skirt element 44a arranged on the outdoor side of the skirt 44 is connected only to the lower frame element 42a arranged on the outdoor side of the lower frame 42, and the skirt element 44b arranged on the indoor side of the skirt 44 is connected to the lower frame. In 42, it is connected only to the lower frame element 42b arranged on the indoor side. A heat insulating space 45 is secured between the lower frame 42 and the width timber 44. The heat insulating space 45 is provided at a position where it is in contact with the lower surface of the connecting member 42c connecting the lower frame elements 42a and 42b and is in contact with the upper surface of the connecting member 44c connecting between the skirting elements 44a and 44b.

As is clear from FIG. 1, a partition member 46 is provided between the lumber elements 44a and 44b. The partition member 46 is a thick plate-shaped member formed of a material having heat insulating properties, and is arranged so that the lower surface thereof is in contact with the upper surface of the basic heat insulating material BD provided on the foundation B. Reference numeral M in the figure is a mortar placed in the space between the lower frame 42 and the foundation B.

According to the lower frame 42 provided with the widthpiece 44 described above, the mortar M placed between the base B and the mortar M does not come into contact with the outside air via the metal portion. That is, the mortar M is in a state where the lower frame 42 is in contact with only the lower frame element 42b on the indoor side, and the mortar 44 is in contact with only the inner frame element 44b on the indoor side. Moreover, a series of heat insulating lines connecting the basic heat insulating material BD to the connecting material 42c of the lower frame 42 via the partition member 46, the connecting material 44c of the widthpiece 44 and the heat insulating space 45 are formed between the mortar M and the outdoor. Will be done. Therefore, the entry of the outside air temperature into the indoor side through the lower frame 42, the width timber 44, and the mortar M is significantly suppressed.

On the other hand, as shown in FIGS. 20 and 21, the upper frame 41 and the left and right vertical frames 43 of the frame body 40 are made of a metal frame material 413A extruded from a metal such as an aluminum alloy and a hard resin such as hard PVC, respectively. It is provided with an extruded resin frame material 413B. As is clear from the figure, the upper frame 41 and the vertical frame 43 illustrated in the present embodiment have different basic configurations, although the detailed configurations are different. Therefore, in the following, the basic configuration will be described with one vertical frame 43 shown in FIG. 23 as a representative example, and the same reference numerals are given to the same configurations in the upper frame 41 and the other vertical frame 43. I will do it.

The metal frame material 413A has a metal cylinder portion 413A1 having a deformed hollow shape. The metal cylinder portion 413A1 has a cross-sectional shape in which an end portion on the outdoor side is bent at a substantially right angle toward the outer peripheral side after extending along a prospective direction. The dimension of the metal cylinder portion 413A1 along the prospective direction is smaller than the dimension of the door body 10 along the prospective direction. The inner end surface 413A1a, which is the most indoor side of the metal cylinder portion 413A1, extends in a direction substantially perpendicular to the prospective direction. The metal cylinder portion 413A1 is provided with a hook receiving portion 413A2 on the inner peripheral side edge portion of the inner end surface 413A1a, while the mooring piece portion 413A3 is provided on the outer peripheral side edge portion. The hook receiving portion 413A2 extends along a direction orthogonal to the inner end surface 413A1a, and then bends substantially at a right angle to the outer peripheral side toward the mooring piece portion 413A3. The mooring piece portion 413A3 is a flat plate-like portion extending along a direction orthogonal to the inner end surface 413A1a.

In the subtight material 101 shown in FIG. 21, the base end portion 101a is formed of a hard resin, while the tip end portion in contact with the door body 10 is formed of a soft resin.

On the other hand, as shown in FIG. 23, the resin frame material 413B has a resin cylinder portion 413B1 having a substantially rectangular hollow shape. The outer end surface 413B1a located on the outdoor side of the resin cylinder portion 413B1 extends in a direction substantially perpendicular to the prospective direction. The resin cylinder portion 413B1 is provided with a hook insertion portion 413B2 and a support protrusion 413B3 on the outer end surface 413B1a. The hook insertion portion 413B2 protrudes in a direction substantially perpendicular to the portion of the outer end surface 413B1a located on the inner peripheral side, and then bends toward the inner peripheral side. The tip of the hook insertion portion 413B2 is inclined so that the plate thickness gradually decreases toward the tip. The support projection 413B3 projects in a direction substantially perpendicular to the portion located on the outer peripheral side of the outer end surface 413B1a. The protruding height of the support protrusion 413B3 is the same as the protruding height of the hook insertion portion 413B2.

Further, the resin cylinder portion 413B1 is provided with a locking projection 413B4 on a side surface located on the outer peripheral side, and a guide surface 413B5 is provided on an outer peripheral side corner portion of the outer end surface 413B1a. The locking projection 413B4 projects from the side surface of the resin cylinder portion 413B1 to the outer peripheral side. The locking projection 413B4 is set so that the dimension along the prospective direction from the tip of the support projection 413B3 is equal to the distance from the inner end surface 413A1a to the engagement projection 413A4 in the metal cylinder portion 413A1. The guide surface 413B5 is a continuous flat surface from the tip of the support projection 413B3 to the locking projection 413B4, and is inclined toward the indoor side so as to gradually become the outer peripheral side. A mounting piece 413B6 is provided on the inner peripheral side surface of the resin cylinder portion 413B1. The mounting piece 413B6 is a resin cylinder portion 413B1 protruding from a portion located on the indoor side toward the inner peripheral side. A finding mounting groove 413B7 is provided on the finding surface facing the outside at the tip of the mounting piece 413B6. As shown in FIGS. 20 and 21, a main tight material 102 for ensuring watertightness between the door body 10 and the finding surface 10a facing the indoor side is mounted on the finding mounting groove 413B7. Reference numeral 48 in the drawing is a cover member for covering the finding surface on the indoor side of the resin cylinder portion 413B1 and the mounting piece 413B6. The cover member 48 is formed of a metal such as an aluminum alloy.

Further, the resin cylinder portion 413B1 is provided with a contact protrusion 413B8 at an edge portion located on the inner peripheral side of the outer end surface 413B1a. The contact protrusion 413B8 is a protruding portion formed of a soft resin, and protrudes from a corner of the resin cylinder portion 413B1 toward the outdoor side toward the inner peripheral side. The resin cylinder portion 413B1 having a portion molded by a hard resin and a portion molded by a soft resin can be easily integrally molded by applying a double mold.

In addition to the above configuration, the resin frame material 413B of the upper frame 41 is provided with a cover fin portion 413B9 in the resin cylinder portion 413B1 as shown in FIGS. 20 and 22. The cover fin portion 413B9 is a thin plate-shaped portion protruding inward from a portion slightly on the indoor side of the abutting protrusion 413B8 toward the outdoor side. Like the contact protrusion 413B8, the cover fin portion 413B9 is integrally molded with the resin cylinder portion 413B1 by a soft resin.

As shown in FIG. 24, the metal frame material 413A and the resin frame material 413B having the above-described configuration have the inner end surface 413A1a of the metal cylinder portion 413A1 and the outer end surface 413B1a of the resin cylinder portion 413B1 slightly tilted. First, insert the tip of the hook insertion portion 413B2 into the hook receiving portion 413A2. From this state, if the metal frame material 413A and the resin frame material 413B are relatively rotated so that the inner end surface 413A1a and the outer end surface 413B1a are substantially parallel, the mooring piece portion 413A3 guides along the guide surface 413B5. Then, as shown in FIGS. 20 and 21, the engaging projection 413A4 of the mooring piece portion 413A3 is locked to the locking projection 413B4. After that, if the connecting screw 50 is screwed from the outer end surface 413B1a of the resin cylinder portion 413B1 to the inner end surface 413A1a of the metal cylinder portion 413A1, the metal frame material 413A and the resin frame material 413B are maintained in a connected state. The upper frame 41 and the left and right vertical frames 43 are configured.

The upper frame 41 and the left and right vertical frames 43 form a frame 40 by being framed together with the lower frame 42, and the fixing screws 51 are respectively placed on the prospective surface of the skeleton BB via the metal cylinder portion 413A1 and the resin cylinder portion 413B1. Is screwed together, and the fixing screw 52 is screwed into the finding surface of the skeleton BB via the screw screw piece 413A5 to be attached to the skeleton BB. Here, in the upper frame 41 and the left and right vertical frames 43, the boundary surface X between the inner end surface 413A1a of the metal cylinder portion 413A1 and the outer end surface 413B1a of the resin cylinder portion 413B1 is formed on the inner peripheral side prospective surface of the frame body 40. Will be located. However, in this frame body 40, as shown in FIG. 25, the contact protrusion 413B8 provided on the resin cylinder portion 413B1 is appropriately deformed by abutting on the hook receiving portion 413A2 of the metal cylinder portion 413A1, and the hook receiving portion is deformed as appropriate.

Further, in the left and right vertical frames 43, the tip end portion of the contact protrusion 413B8 protruding from the prospective surface of the frame body 40 is covered by the base end portion 101a of the subtight material 101 mounted in the prospective mounting groove 413A7 of the metal cylinder portion 413A1. It is in a broken state. Further, in the upper frame 41, as shown in FIG. 20, the cover fin portion 413B9 provided on the resin cylinder portion 413B1 is the boundary surface X between the inner end surface 413A1a of the metal cylinder portion 413A1 and the outer end surface 413B1a of the resin cylinder portion 413B1. It is arranged so as to cover. Therefore, according to the frame body 40, there is no possibility that water will infiltrate the boundary surface X between the metal frame material 413A and the resin frame material 413B. The inner peripheral surface of the resin frame material 413B is covered with the subtight material 101, the maintight material 102, the cover member 48, and the cover fin portion 413B9. Therefore, the resin frame material 413B is not exposed, and the boundary surface X between the metal frame material 413A and the resin frame material 413B is not exposed. As a result, according to this fitting, the upper frame 41 and the vertical frame 43 of the frame body 40 are fitted as if they are composed of only the metal frame material 413A, which is advantageous in terms of design and weather resistance. It becomes.

With respect to the frame body 40 attached to the skeleton BB, hinges 1 were interposed between the aggregate 11 located at the hanging source of the door body 13 and one of the vertical frames 43, respectively, so as to follow the vertical direction. The door body 10 is supported so as to open toward the outdoor side with the hinge shaft as the center. As shown in FIGS. 1, 2, 20, and 21, in this fitting, the size of the metal frame material 413A along the expected direction is smaller than the size of the door body 10 along the expected direction. The boundary surface X between the 413A and the resin frame material 413B is positioned along the finding direction on the outdoor side of the door body 10 with respect to the finding surface 10a facing the room. Moreover, when the door body 10 is closed, the resin frame material 413B of the frame body 40 and the resin edge material 20B of the door body 10 face each other, and the metal portion exposed to the outside in the frame body 40 and the door body 10. 413A and 20A exist only on the outdoor side of the finding surface 10a facing the interior of the door body 10. Therefore, according to this fitting, the entry of the outside air temperature through the metal frame material 413A of the frame body 40 and the metal edge material 20A of the edge material 20 stops outside the finding surface 10a facing the room of the door body 10. It is possible to suppress the influence on the room temperature.

In the above-described embodiment, the door body 10 that is openably and closably supported by the frame body 40 via the hinge 1 is illustrated, but the present invention is not necessarily limited to this. Further, the frame body 40 includes a metal frame material 413A and a resin frame material 413B, but the frame body 40 is not necessarily limited to this. Further, as the aggregate 11, the one provided with the resin bone portion 11A and the metal bone portion 11B is illustrated, but the aggregate 11 is not necessarily the one provided with the resin bone portion 11A.

Further, in the above-described embodiment, when the sandwiched member 21 is formed separately from the edge member 20, the edge is prevented from moving relative to the edge member 20 in all directions. Since it is attached to the material 20, it is advantageous in terms of the attachment strength of the edge material 20.
