[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to fittings that are openably and closably installed in ordinary windows and doorways such as entrances of buildings, doors of arbitrary openings, sliding doors, and shutters.

[0002]

2. Description of the Related Art In recent years, in order to save energy by forming a comfortable living space and reducing energy used for heating and cooling, heat insulation performance of outer walls and fittings is emphasized. For this reason, fittings having heat insulation performance have been used as fittings such as entrance doors and entrance sliding doors.

As a fitting having such heat insulating properties, it is composed of a frame framed in a rectangular shape, steel plates attached to both surfaces in the prospective direction of the frame, and a heat insulating member filled between the steel plates. There is known a heat-insulating door including a door panel main body having an opening for lighting formed in a portion thereof.

In this adiabatic door, the glass disposed in the lighting opening is sandwiched between the decorative material provided on the outdoor surface side of the door panel body and the frame provided around the indoor opening of the door panel body. Has been done. Specifically, the decorative material on the outside has an outside fin that extends into the opening and is applied to the outside surface of the glass, and a mounting piece that extends beyond the outside of the glass to the frame on the inside. The indoor fin is provided on the indoor frame, and the indoor fin is applied to the inner surface of the glass. These fins and mounting pieces are respectively provided along the four edges of the glass, and the four edges of the glass are sandwiched between the fins of the decorative material and the frame by screwing the frame to the mounting pieces of the decorative material. It is like this. That is,
The decorative material and the frame also serve as a holding frame for holding the glass.

[0005]

By the way, if such a decorative material for a heat insulating door is formed by using a metal material such as aluminum, the temperature of the decorative material rises when the decorative material is exposed to direct sunlight, and the thermal expansion of the decorative material occurs. To do. At this time, since the decorative material is also used as a holding frame for holding the glass, the structure of the opening portion is such that, even when the decorative material thermally expands, the attachment piece of the decorative material hits the inner surface of the opening portion. It must be configured so that it does not exist.

For this reason, conventionally, the attachment piece of the decorative material and the inner surface of the opening are provided so as to be separated from each other by a predetermined distance so that even if the decorative material thermally expands, the expansion can be absorbed. Since the outdoor fins of the decorative material need to securely hold the glass even after the thermal expansion of the decorative material, it is necessary to increase the dimension of the decorative material to the glass in consideration of the amount of expansion of the decorative material. It was

However, if the outside fin of the decorative material has a large hanging dimension with respect to the glass, there is a problem in that the appearance dimension of the decorative material is increased and the opening area is reduced accordingly.

An object of the present invention is to provide a fitting in which the size of the glass holding frame can be reduced and the opening area of the lighting opening can be increased.

[0009]

A fitting according to claim 1 is a base unit having a lighting unit, and a part of the exterior surface of the basic unit excluding the lighting unit attached to the exterior surface side of the basic unit. or a supplementary unit to cover the entire surface, the said base unit, the panel holding frame is provided for holding the translucent panel which is provided on the lighting unit, the supplementary unit is this panel holding frame and the separate The above
Holds the outer circumference of the accessory unit on the outer circumference of the basic unit
An edge material to be installed is provided.
Allows expansion and contraction of the accessory unit in the in-plane direction between
It is characterized in that a gap is formed .

The basic unit means a unit having the rigidity, waterproof property, heat insulating property, sound insulating property, etc. required for a fitting by itself. Specifically, the upper frame, the lower frame, and the left and right vertical frames, which are assembled in four round frames,
Indoor and outdoor surface materials attached inside and outside of this frame, and a honeycomb core (paper honeycomb etc.) having heat insulating properties such as paper and resin placed between the indoor and outdoor surface materials, urethane resin, etc. And the like, which are provided with a heat insulating member. However, the present invention can be applied even when the basic unit does not have a heat insulating property.

In such a fitting, since the accessory unit provided on the outdoor surface side of the basic unit is separate from the panel holding frame that holds the translucent panel such as glass, it is directly exposed to the accessory unit. Even if the panel holding frame is thermally expanded by being irradiated with sunlight, the panel holding frame does not thermally expand, and it is not necessary to provide a space for absorbing the thermal expansion between the opposing surfaces of the panel holding frame and the opening provided for lighting. Therefore, the found size of the panel holding frame can be reduced, and the opening area of the lighting portion can be increased. Further, such an effect can be obtained even when the auxiliary unit contracts due to low temperature such as at night or in winter, that is, it can correspond to expansion and contraction of the auxiliary unit. In addition, the accessory unit receives heat from direct sunlight
Even if it does, the amount of displacement due to this thermal expansion can be absorbed in the gap.

Further, the panel holding frame is provided with a fin portion for holding the outdoor surface of the translucent panel, and the decorative frame arranged on the indoor side of the panel holding frame is the interior of the translucent panel. It is preferable that another fin part that holds the surface is provided, and the translucent panel is sandwiched between these fin parts. In the case of such a configuration, since it is not necessary to hold the translucent panel by the panel holding frame alone, the structure of the panel holding frame can be simplified and the translucent panel can be easily held.

Further, it is preferable that the auxiliary unit covers a part or the whole of the outer surface of the panel holding frame. According to such an accessory unit, since the accessory unit is configured so as to cover the panel holding frame, it is possible to limit the irradiation of direct sunlight to the panel holding frame and prevent thermal expansion of the panel holding frame.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. [First Embodiment] Fig. 1 is an external view showing a heat insulating door 1 as a fitting according to the first embodiment of the present invention, Figs. 2 and 3.
Is a longitudinal sectional view and a transverse sectional view of the heat insulating door 1, FIG. 4 is an enlarged view showing a main part in the horizontal sectional view, and FIG. 5 is a heat insulating door 1.
It is an exploded perspective view which shows typically.

The heat-insulating door 1 is a so-called single-opening door, and is composed of a door frame 10 provided at the entrance opening of a building and a door plate 20 arranged in the door frame 10, and the door plate 20 is mainly insulated. Is given. Note that such an adiabatic door may be a double-opening door as in the present embodiment, or a double-opening type door, that is, a parent-child door provided with a sleeve panel that is usually closed.

The door frame 10 is formed by arranging an upper frame 11, a lower frame 12, and left and right vertical frames 13 each of which is made of extruded aluminum frame, for four circumferences. Attachments 14, 15 and 16 having locking claws 14A, 15A and 16A are detachably attached to the lip grooves 11A to 13A provided on the indoor side of each of the frame members 11 to 13 by one-touch type. ing.

Examples of such attachments 14 to 16 include resin-made ones and aluminum-made ones.
Further, as the attachments 14 and 16 for the upper frame 11 and the vertical frame 13, particularly, those without an angle shown by a solid line and those with an angle shown by a chain line are prepared. These attachments 14 to 16 are appropriately selected and used from those having different materials and shapes, thereby increasing the fit and design variation of the door frame 10 without changing the frame members 11 to 13. It is possible.

On the other hand, the door plate 20, as shown in FIG.
A door plate main body 21 as a basic unit, a shield 22 as an incidental unit that covers substantially the entire outer surface of the door plate main body 21 except for the inner window 24, and a decorative frame 23 that covers the four inner peripheral edges of the inner window 24. It has and. The middle window 24 serves as a daylighting section according to the present invention.

The door plate main body 21 is composed of an upper frame 211, a lower frame 212, and a left and right vertical frames 213, each of which is made of a hollow aluminum extruded frame, and a frame assembly 214 formed by arranging four frames.
A paper honeycomb core 215 having a heat insulating property arranged in the frame 214, and the paper honeycomb core 215.
And the steel plate 21 joined to the inside and outside of the frame 214
6,217, with an opening 218 for the middle window 24 in the center
have. Then, the paper honeycomb core 215 imparts heat insulating performance to the door plate body 21,
It is difficult for the heat transfer inside and outside in 1 to be performed.

Further, in FIG. 3, one vertical frame 213 of the frame assembly 214 has a larger cross-sectional dimension than the other, and is in contact with the steel plates 216 and 217 with a larger contact area. Therefore, a step portion 213A that is recessed to the outside of the room is provided on the indoor surface of the vertical frame 213, and a heat insulating sheet 213B is attached so as to fill the step portion 213A. That is, since the vertical frame 213 has a large cross-sectional dimension, there is a concern that the heat on the outdoor side may affect the indoor side, but by contacting most of the indoor surface with the steel plate 217 via the heat insulating sheet 213B, The heat of the outdoor steel plate 216 transmitted through the vertical frame 213 is hard to reach the indoor steel plate 217 (the indoor surface of the door plate body 21).

In the frame assembly 214 constituting the door plate body 21, the upper end of the upper frame 211 is closed by an upper edge member 219 which is laid across the rising portion, as shown in FIG. Two drainage spaces 220 and 221 are formed along the longitudinal direction of 211. Such drainage spaces 220 and 221 serve as drainage flow paths for rainwater and the like, as well as the electric wiring 2 for the electric lock 223 (FIG. 3).
It is also used as a space for 23A (illustrated by a circular dashed line in FIG. 2) and can be easily maintained by removing the upper edge material 219. Further, in FIG. 2, a lower edge member 222 is also applied to the lower frame 212 from below to be screwed.

Each vertical frame 213 of the frame assembly 214 is hollow with a rectangular cross section. As shown on the right side of FIG. 3, one vertical frame 213 has a hollow portion with respect to the vertical frame 13 of the door frame 10. The electric lock 223 to be disengaged is housed. As a result, even if rainwater enters through the screw holes of the vertical frame 213 for fixing the electric lock 223, the rainwater will fall along the hollow portion of the vertical frame 213, and the rainwater will fall onto the paper honeycomb core 215. There is no worry to reach. The same applies to the vertical edge material 224 drilled in the vertical frame 213 and rainwater entering from the screw holes for fixing the door closer (not shown). further,
As shown on the left side in FIG. 3, such a configuration is similar in the other vertical frame 213, and the vertical edge member 22 is attached to the vertical frame 213.
In addition to No. 4, even if the hinge 25 for connecting to the door frame 10 is fixed, rainwater that enters from this fixed portion does not reach the inside of the paper honeycomb core 215.

2 and 4, the inner window 24 is provided with a frame body 225 as a panel holding frame which is housed in the opening 218 of the door plate body 21 separately from the shield 22. By making the frame body 225 and the shield body 22 separate from each other, the thermal expansion of the shield body 22 caused by direct sunlight irradiation is suppressed from affecting the inner window 24 side.

The frame body 225 has an upper frame 226, a lower frame 227, and left and right vertical frames 228 made of an extruded aluminum material, which are welded or bonded to each other, or 45 ° to each other via an L-shaped bracket.
It is joined and framed. A multi-layer glass panel 229 as a translucent panel is arranged in the frame body 225, and an outdoor surface of the glass panel 229 is provided with a sealing material 230 on the fins 226A, 227A, 228A on the outdoor side of each of the frame materials 226 to 228. The fin portion 23 on the inner peripheral edge of the decorative frame 23, which is supported via
It is supported by the seal member 231 at 2A.

The decorative frame 23 is a frame in which four aluminum or resin frame members 232 having the same cross-sectional shape are welded, adhered, or joined at 45 ° to each other via a bracket, and are framed from the indoor side. The design is improved when viewed (inside view).

In such an inner window 24, the frame 225 is inserted from the outdoor side toward the indoor side, and the outer peripheral edge portion of the frame 225 on the outdoor side is locked to the outdoor surface of the door plate body 21. After that, the glass panel 229 is arranged in the frame body 225, and the decorative frame 23 is screwed to the frame body 225, whereby the glass panel 229 is fixed between the fins 226A to 228A, 232A of the frame body 225 and the decorative frame 23. And the frame body 225 and the decorative frame 23 are fixed to each other so as to sandwich the door plate body 21. At this time, as shown by the chain double-dashed line, a waterproofing treatment is applied to the boundary portion between the outer periphery of the frame body 225 and the outdoor surface of the door plate body 21 by taping with the waterproofing material 233.

Below, a shield 22 for covering the door plate body 21 is provided.
Will be explained in detail. In FIGS. 1 and 5, the shield 22
Is an upper cross member 23 that covers the four edges of the exterior surface of the door plate body 21.
4, lower horizontal members 235, and left and right first vertical members 236. These members 234 to 236 are formed as plate materials by extruded aluminum members, and a pair of second vertical members 237 are arranged inside each first vertical member 236. A pair of third vertical members 238 that covers the left and right edges of the center window 24 is disposed inside. The innermost third vertical member 238 and the upper and lower horizontal members 234 and 235 cover the entire outer surface of the frame body 225 that forms the middle window 24. The temperature of the vertically long shield 22 is increased by direct sunlight irradiating the outdoor side surface, and the vertically elongated shield 22 is thermally expanded in the vertical direction.

The upper and lower horizontal members 234 and 235 and the first vertical member 23
No. 6 is joined to the first vertical member 236 by 90 ° in the state where the first vertical member 236 is passed through (vertical pitch / vertical passing), and is formed into an overall frame shape. At this time, as shown in FIG. 3, in the first vertical member 236, the prospective piece 236A on the outer peripheral side is fixed to the outdoor side of the vertical edge member 224 by a screw 236B. The screw hole (not shown) formed in the prospective piece 236A is a long hole. Expected piece 236C on the other side of the first vertical member 236
The lip groove 236D is provided in the lip groove 236D.
D is a resin guide member 2 attached to the door plate body 21 side.
It is fitted with 39.

That is, the vertically elongated first vertical member 236 causes thermal expansion in the vertical direction when exposed to direct sunlight, but interference with the screw 236B is avoided by the elongated hole on one side of the left and right sides. The other side slides along the guide member 239 so that the heat expansion as the first vertical member 236 is performed without being hindered by the door plate body 21.

The guide member 239 is previously fitted to the first vertical member 236, and each plate member 234 assembled in a frame shape.
At the same time as attaching ~ 236 to the door plate body 21, it is attached to the outdoor surface of the door plate body 21. In addition, the guide member 2
To attach 39, a surface fastener may be used instead of an adhesive or a double-sided tape. The material of the guide member 239 may be metal, but it is preferable to use a resin having a low thermal conductivity, which is difficult to transfer heat to the door plate body 21 side. Further, the prospective pieces 236A and 236C of the first vertical member act as reinforcing ribs themselves, and are also useful for improving the rigidity of the first vertical member 236.

By the way, an upper cross member 234 assembled in a frame shape,
In the lower horizontal member 235 and the first vertical member 236, as shown in FIG.
As shown in, the lower end of the lower horizontal member 235 is placed on the lower edge member 222 of the door plate body 21, and the upper end of the upper horizontal member 234 is locked to the upper edge member 219. At this time, the upper cross member 234
On the side, a gap 240 is provided between the upper end of the upper horizontal member 234 and the flat portion of the upper edge member 219.

That is, since the irradiation area of the direct sunlight is larger in the first vertical member 236 than in the upper and lower horizontal members 234 and 235, the lower end of the lower horizontal member 235 is placed on the lower edge member 222. In the present embodiment, the upper horizontal member 234 moves upward as the first vertical member 236 thermally expands in the vertical direction. On this occasion,
A gap 240 between the upper horizontal member 234 and the upper edge member 219 absorbs the amount of displacement due to thermal expansion, and causes the thermal expansion even on the upper side of the shield 22 without interfering with the door plate body 21 side. Is possible.

In the present embodiment, the lower edge material 222
The outdoor end of the shield is bent upward, and the upper transverse member 234, the lower transverse member 235, and the first longitudinal member 2 which are frame-shaped and are assembled together.
When 36 is attached to the door plate main body 21 in a loose manner using the upper gap 240, the lower horizontal member 235 is connected to the lower edge member 222.
It can be easily dropped by guiding it at the bent portion. The lower horizontal member 235 is also attached to the door plate body 21 via two horizontal guide members 239. In addition, the upper and lower horizontal members 234 and 235 and the first vertical member 2
In consideration of the fact that 36 is slightly thermally expanded in the finding direction, the screw 236B for fixing the first vertical member 236 and the prospective piece 2 described above are provided.
An elastic body such as a rubber washer that absorbs the displacement due to the thermal expansion is interposed between the elastic body and 36A.

Second and third vertical members 23 constituting the shield 22.
7, 238 are also extruded shape members made of aluminum, and the first vertical member 2
Like 36, it is a plate material. First, the third vertical member 238 is
As shown in FIG. 3, by fitting the lip grooves 238B provided on the left and right prospective pieces 238A into the two guide members 239, they are vertically slidably attached to the door plate body 21 and the frame body 225. There is. On the other hand, in the second vertical member 237, the prospective pieces 237A on both the left and right sides of the second longitudinal member 237 face each other of the first vertical member 236 and the third vertical member 238.
36C, 238A provided with engaging portions 236E, 238
It is attached by engaging with C and can also slide up and down.

The upper and lower horizontal members 234 and 235 are provided on the upper and lower ends of the second and third vertical members 237 and 238, respectively.
Are swallowed by each. That is, in FIG. 2, the second and third prospective pieces 234A on the lower side of the upper transverse member 234 and the prospective piece 235A on the upper side of the lower transverse member 235 are provided.
Notches (not shown) are provided that follow the outer shape of the vertical members 237 and 238, and the upper and lower ends of the notches (not shown) are swallowed in the form of a basket.

The lower ends of the second and third vertical members 237 and 238 are
It is placed on another prospective piece 235B provided below the prospective piece 235A of the lower horizontal member 235. Upper horizontal member 234
Is also provided with a similar prospective piece 234B. Inside the interior of each of the prospective piece 234B and the prospective piece 235B,
Locking portions 234C and 235C that are locked to the upper and lower ends of the second and third vertical members 237 and 238 are provided. Therefore, the lower side of the upper horizontal member 234 near the center window 24 and the upper side of the lower horizontal member 235 are the second and third vertical members 2 attached to the door plate body 21.
37, 238 is reliably locked, and flapping to the outside of the room is suppressed. The second and third vertical members 2
37, 238, each prospective piece 237
A and 238A improve their rigidity.

In the shield 22 as described above, the upper cross member 23
4, the lower horizontal member 235 and the first to third vertical members 236 to 238 are prospective pieces 234A, 235A, 236A, 237A, 23.
By having 8A, the outdoor surface is separated from the door plate main body 21, and each horizontal member 234, 235 and each vertical member 236-2.
Air layer 2 as a heat insulating layer between 38 and the door plate body 21
41 are formed. The air layer 241 makes it difficult for the heat of the shield 22 to be transferred to the door plate body 21, and reliably suppresses heat expansion and deterioration of the door plate body 21 due to heat. In addition, such an air layer 241 is well communicated with the outside,
Air may be circulated between the inside of the air layer 241 and the outside. In such a case, since heat can be radiated favorably on the back surface side of the shield 22, the shield 22 is exposed to direct sunlight. Can suppress the temperature rise of the outdoor surface, and the door plate body 21
Not only can the thermal expansion of the shield 22 itself be prevented.

In this embodiment as described above, the upper horizontal member 234, the lower horizontal member 235, and the first to third vertical members 236 to 238.
Is previously assembled as the shield 22, and the lower cross member 23
5, the first and third vertical members 236 and 238 have guide members 23.
Insert 9 in advance. From this state, the shield 22 is assembled to the door plate body 21 to complete the door plate 20. The installation of the entire heat insulating door 1 is performed in the same procedure as that of normal door construction. That is, the door frame 10 may be fixed to the entrance opening portion of the building, and the door plate 20 may be attached to the door frame 10 via the hinge 25 and the door closer.

According to this embodiment as described above, the following effects can be obtained. 1) The door plate 20 of the heat insulating door 1 is provided with a middle window 24, and the frame body 225 and the shield body 22 that constitute the middle window 24 are provided.
Since it is a separate body from the above, thermal expansion of the shield 22 caused by direct sunlight irradiates the frame 225, the internal glass panel 229, and the opening 218 of the door plate main body 21 provided for the inner window 24. There is no fear of being obstructed by such things as the shield 2
A heat elongation of 2 can be reliably tolerated. Therefore, even if the shield 22 is exposed to direct sunlight and greatly expands in the vertical direction, the frame 225 does not expand thermally, and thus the frame 225 and the opening 218.
It is not necessary to provide a space for absorbing thermal expansion between the inner surface of the frame body 225 and the upper surface of the frame body 225, especially the upper and lower frames 226 and 227, and the found size H (FIG. 2) can be reduced, and the opening area of the middle window 24 can be increased.

2) The frame 225 is provided with fins 226A to 228A for holding the outer surface of the glass panel 229, and the decorative frame 23 is provided with another fin 232A for holding the inner surface of the glass panel 229. , The glass panel 229 between these fins 226A-228A, 232A.
Since the frame body 225 is sandwiched, it is not necessary to hold the glass panel 229 by the frame body 225 alone, and the structure of the frame body 225 can be simplified. In addition, the glass panel holding work is performed by the frame 22.
Makeup frame 23 such as 5 with the makeup frame 23 fixed with screws
It is efficient because it can be done at the same time as the fixing work.

3) Since the shield 22 covers the entire outer surface of the frame 225, it is possible to limit the direct sunlight to the frame 225 and prevent the frame 225 itself from being thermally expanded.

4) Since the door plate 20 is provided with the door plate body 21 having a heat insulating property and the shield 22 arranged outside the door plate body 21, the outdoor surface of the door plate body 21 is irradiated with direct sunlight. It is possible to prevent the temperature from rising and prevent the temperature of the outdoor surface from rising. Therefore, since the temperature difference between the outdoor surface and the indoor surface can be reduced by blocking the irradiation of the direct sunlight to the door plate main body 21, it is possible to prevent the thermal expansion of the outdoor surface, and thus the basic performance as a fitting is required. It is possible to effectively prevent the warp of the door plate body 21 to be broken, and to prevent deterioration due to ultraviolet rays.

5) Since the outdoor side of the door plate main body 21 is covered with the shield 22, rainwater and the like do not fall directly onto the door plate main body 21, water stopping performance can be improved, and deterioration due to rain water can be ensured. It can be prevented and weather resistance and durability can be improved.

6) An upper edge material 219, a lower edge material 222, which holds the outer periphery of the shield 22, is provided on the outer periphery of the door plate body 21.
And the left and right vertical edge members 224 are provided, and a gap 240 is formed between the upper edge member 219 and the shield 22 to allow the shield 22 to expand and contract in the vertical direction. Even if it receives thermal expansion due to sunlight, the amount of displacement due to this thermal expansion can be absorbed by the gap 240, and the shield 22 can be prevented from attempting to spill outside. In addition, the gap 240
Since the shield 22 is provided with no problem, it does not cause any problem even if the shield 22 is formed of a heat-expandable metal material.
Each horizontal member 234, 235, each vertical member 236-23
8 can be formed of an extruded aluminum material, and the workability can be improved.

7) Second and third vertical members 237 of the shield 22,
238 is inserted in the upper cross member 234 and the lower cross member 235 in the form of a seal cage, and each of the cross members 234, 23.
Since the vertical portions 237C and 235C are provided with locking portions 234C and 235C, respectively, which are locked to the insides of the vertical members 237 and 238, the horizontal members 23 are fixed to the door plate main body 21 and the horizontal members 23, respectively.
4, 235 can be securely locked, and the lateral members 234, 235 can be prevented from flapping outside. Specifically, the middle window 2
The second and third vertical members 23 attached to the door plate main body 21 are arranged on the lower side of the upper horizontal member 234 near 4 and the upper side of the lower horizontal member 235.
7, 238 can be reliably locked, and its fluttering can be prevented.

8) Since the shield 22 covers up to the portion along the outer circumference of the outdoor surface of the door plate body 21, it is possible to make it difficult for rainwater to enter the outer peripheral portion of the outdoor surface and the end face side of the door plate body 21. Therefore, the electric lock 22 is provided on the end face side of the door plate body 21.
3, even when fitting parts such as hinges 25 and door closers are fixed with screws, there is no concern that rainwater will enter through the screw holes, and the waterproofness of the door plate 20 can be maintained well, and the door plate 20 can be used well for doors. be able to. Since the door lock components such as the electric lock 223, the hinge 25, and the door closer are attached to the door plate main body 21 having rigidity as the door plate in the door plate 20, each component is securely attached to the door plate 20. In addition, it is possible to improve the durability of the heat insulating door 1 without fear that the mounting portions of those constituent members will be deformed or the like and will not function during the opening and closing of the door plate 20.

9) Since the shield 22 is provided with the air layer 241 as a heat insulating layer between the shield 22 and the door plate body 21, even if the shield 22 is made of aluminum having a high thermal conductivity, the shield 22 is made of aluminum. The heat generated by irradiating 22 to the air layer 241
It is possible to prevent the heat from spreading to the side of the door plate main body 21 and to prevent the thermal expansion of the outdoor surface of the door plate main body 21 and the deterioration of the outdoor surface due to heat.

10) Since the door plate 20 is limited in direct sunlight applied to the door plate body 21, a large difference does not occur in the temperature of the inside and outside surfaces of the door plate body 21, and warpage due to thermal expansion is prevented. It is particularly effective as a fitting having a heat insulating property in which a temperature difference easily occurs.

11) First vertical member 236 forming the shield 22
At the time of thermal expansion of the first vertical member 236, the long hole avoids the interference with the screw 236B on one side, and the other side slides along the guide member 239. The heat expansion can be allowed without being hindered by the door plate body 21 side. In addition, the second vertical member 237 is slidably engaged between the first and third vertical members 236 and 238, and the third vertical member 238 is also slidably attached to the door plate body 21 via the guide member 239. Therefore, the heat expansion of these vertical members 237 and 238 can be allowed without being hindered by the door plate body 21 side. Therefore, when the entire shield 22 is thermally expanded in the vertical direction, even if the shield 22 is attached to the door plate body 21, the thermal expansion can be allowed, and the amount of displacement due to the thermal expansion is absorbed in the gap 240 described above. Together with this, it is possible to more reliably prevent the occurrence of warpage in the shield 22.

12) The shield 22 may have a vertically long shape, so that heat expansion in the vertical direction is mainly allowed. However, in the present embodiment, the lower horizontal member 235 is provided with a horizontal guide member 239. Because the elastic member such as a rubber washer is attached to the door plate main body 21 or for fixing the first vertical member 236 to the door plate main body 21 with a screw, the shield 22 may be slightly stretched in the lateral direction. Is definitely acceptable.

13) When the shield 22 is attached to the door plate main body 21 by a spatula type, the lower end is guided by the bent portion of the lower edge member 222 of the door plate main body 21, and the lower end can be easily dropped. , Work can be done quickly and surely.

14) Prospective pieces 234A and 234 are provided on the horizontal members 234 and 235 and the vertical members 236 to 238 of the shield 22.
B, 235A, 235B, 236A, 236C, 237
Since A and 238A are provided, the rigidity thereof can be improved, and even when the shield 22 is preassembled, it does not bend and can be easily handled. Further, the improvement in rigidity can sufficiently counteract negative pressure in strong winds. In addition, prospective pieces 234A, 234B, 235
A, 235B, 236A, 236C, 237A, 238
Since A also acts as a radiation fin, the heat of the shield 22 can be efficiently released to the air layer 240, and the shield 2
It is possible to suppress the temperature rise of 2 and make the thermal expansion of the shield 22 less likely to occur.

15) Since the attachments 14 to 16 attached to the door frame 10 are appropriately selected and used from those having different materials and shapes, the attachments 14 to 16 can be accommodated as the door frame 10 without changing the frame members 11 to 13. It is possible to increase variations in terms of design.

[Second Embodiment] FIGS. 6, 7, 8, and 9.
FIG. 4 shows an external view, a longitudinal sectional view, a transverse sectional view, and an enlarged view of the transverse section of the heat insulating door 2 according to the second embodiment of the present invention. In this embodiment, the same members as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted or simplified.

As a supplementary unit of the present invention, the heat insulating door 2 is provided with a decorative frame 26 which covers only the peripheral portion of the opening 218 of the door plate body 21 on the outdoor side. Therefore, in the heat insulating door 2, substantially the entire outer surface of the frame 225 is covered, but most of the outer surface of the door plate body 21 is exposed. Further, the decorative frame 26 is formed by frame-forming a shape member 245 made of aluminum and having the same cross-sectional shape by 45 ° joining.

In such a decorative frame 26, the frame body 225 for the middle window 24 is provided with screws 2 on the indoor side of the shape members 245 on the left and right sides.
It is fixed at 48. Further, on the indoor side of the frame body 225, as with the first embodiment, a decorative frame 23 for indoor use is screwed. As a result, the opening 2 of the door plate body 21
The area around 18 will be sandwiched between the makeup frames 23 and 26 and the frame body 225. At this time, the screw hole of the frame body 225 formed to penetrate the screw 248 is a long hole (not shown) so as not to interfere with the thermal expansion of the decorative frame 26 in the vertical direction.

On the other hand, in the frame body 225 of this embodiment, the frame members 226 to 228 are mutually screwed at 90 ° with screws 249 (FIG. 9).
They are joined together, and are inserted and arranged from the indoor side into the opening 218 of the door plate body 21. Also, the door plate body 2
On the outdoor surface of No. 1, a double-sided decorative molding 246 made of an extruded shape member made of aluminum or resin is attached by an appropriate adhesive means such as a double-sided tape, an adhesive, a surface fastener.

In the present embodiment, first, a tape-shaped waterproof material 233 (FIGS. 7 and 9) is attached to the interior surface of the framed makeup frame 26, and the makeup frame 26 is attached to the door plate body 2.
The first opening 218 is applied from the outdoor side. As a result, a part of the water blocking material 233 comes into close contact with the outdoor surface of the door plate body 21. Next, the framed frame body 225 is housed in the opening 218 from the indoor side and fixed to the decorative frame 26 with screws 248. At this time, the outdoor surface of the frame body 225 is substantially flush with the outdoor surface of the door plate body 21, and faces the water blocking material 23.
3, and the waterproof property is secured at the boundary portion between the door plate body 21 and the frame body 225. After this, the glass panel 229
Is placed inside the frame body 225 from the indoor side, and finally, the decorative frame 23 on the indoor side is screwed to the frame body 225 and the glass panel 229 is held.

According to such an embodiment, although the structure as an accessory unit is different from that of the first embodiment, since the decorative frame 26 on the outdoor side and the frame 225 for the middle window 24 are separate bodies, Even when the makeup frame 26 is thermally expanded by the irradiation of direct sunlight, the thermal expansion of the makeup frame 26 can be allowed without being interfered with by the frame body 225. Therefore, the frame body 225
It is not necessary to provide a space for heat expansion in the part, and the frame 2
The found size H of 25 can be reduced, the opening area of the middle window 24 can be increased, and the effect of 1) described above can be similarly obtained.

Further, in this embodiment, the same effects as 2), 3), and 15) described above can be obtained with the same configuration as that of the first embodiment. Furthermore, since the exterior surface of the door plate body 21 in this embodiment is covered with the decorative frame 26, although slightly, it is not as effective as in the above 4), but direct sunlight to the covered portion of the door plate body 21. Can block the irradiation of
Therefore, there is an effect that the heat expansion of the door plate body 21 can be reduced. As a result, the effect of 10) can be obtained similarly. Further, since the area around the opening 218 of the door plate body 21 is covered with the decorative member 26, there is no concern that rainwater or the like will fall directly onto this portion, so it is not as good as the above 5) effect, but somewhat. Water resistance, weather resistance and durability can be improved.

In addition, in this embodiment, the following effects can be obtained by the configuration not provided in the first embodiment. 16) In the present embodiment, the frame body 225 of the inner window 24 and the shield 2
Since the frame member 225 and the frame member 225 are separate,
It can be assembled by 6-228 90 ° joints. For this reason, since the water blocking treatment of the frame body 225 can be performed by a method usually applied to a general frame, the water blocking treatment can be performed easily and surely.

The present invention is not limited to the above embodiment. In each of the above embodiments, the door plate main body 21 has the heat insulating property by using the paper honeycomb core 215, but the heat insulating structure of the door plate main body is arbitrary, and for example, a paper roll core may be used. Also, as the heat insulating structure, a resin heat insulating material such as expanded polystyrene foam or urethane foam is sandwiched between a resin plate or a metal plate from both front and back surfaces, a thick plate-shaped resin enriched panel, or Alternatively, a wooden panel may be used. Alternatively, a structure in which a resin heat insulating material is filled inside a paper honeycomb core or a paper roll core may be applied. When the door panel main body is made of resin or wood, it is possible to prevent ultraviolet deterioration of the outdoor surface and improve weather resistance and durability by covering it with a shield or a decorative frame on the outdoor side. In addition, the shield and the decorative frame on the outdoor side as described in each of the embodiments may have the same heat insulating structure as that of the door plate body. However, it is included in the present invention even when the door plate body and the shield do not have heat insulating properties.

Further, the door frame as described in each embodiment may be provided with heat insulation. That is, each frame member that constitutes the door frame is composed of, for example, an outdoor member made of an aluminum extruded shape member, an indoor member made of an aluminum extruded shape member, and a heat insulating member made of resin for connecting these indoor and outdoor members. It can be implemented by using a heat insulating profile. And
Such a heat insulating structure can be applied to a basic unit such as a door plate body. For example, each frame that constitutes a frame of the door plate body may be a heat insulating frame member. The heat insulating member used for the heat insulating profile is not limited to one formed by injecting a resin, but may be a plate-shaped heat insulating member that is preformed and is joined by caulking between indoor and outdoor members.

In each of the above-mentioned embodiments, the frame 225 and the decorative frame 23 on the indoor side are also separate bodies, but they may be integrated, and the effect of the above 1) is not impeded. That is, since it does not receive direct sunlight as well as the makeup frame on the indoor side, it does not expand heat and it is not necessary to consider interference with the frame in the opening. However, in such a case, in order to improve the inner appearance of the portion corresponding to the decorative frame, usually, the 45 ° joining of the shape members is performed, so that the portion corresponding to the frame is also joined at 45 °. 16) The effect of 16) may not be obtained.

In each of the embodiments, the frame 225 covers the entire or almost the entire outdoor surface of the frame with the shield 22 and the decorative frame 26. However, when a part of the outdoor surface of the frame is covered, , Even if not covered at all, is included in the present invention. In short, in the present invention, such a frame body and the shield body or the makeup frame may be separate bodies.

The fitting of the present invention is not limited to a door, and may be a sliding door having a shoji. In addition, the shape and material of each member constituting the fitting may be arbitrarily determined as long as the object of the present invention can be achieved.

[0068]

As described above, according to the present invention,
Since the panel holding frame of the lighting unit and the incidental unit are separate bodies, even if the incidental unit is exposed to direct sunlight and thermally expanded, the panel holding frame does not expand thermally. It is not necessary to provide a space for absorbing heat expansion between the surfaces facing the opening. Therefore, there is an effect that the found size of the panel holding frame can be reduced and the opening area of the lighting portion can be increased.
