DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door, a sliding door and the like having a picture frame and a panel, and more particularly to a door and a sliding door suitable for an energy-saving type house where importance is placed on heat insulation and comfortable living. It is related to fittings such as. More specifically, a fitting that employs a heat-insulating material for the door body and the panel, etc., and places importance on blocking heat conduction from the outer surface side to the inner surface side of the fitting such as a door having a frame and a panel,
That is, the present invention relates to a structure that can be suitably used for doors, sliding doors, and other fittings that emphasize the heat insulation of the fitting itself.

[0002]

2. Description of the Related Art In buildings such as houses, energy saving and comfortable habitability have been emphasized for a long time, and even in private houses, heat insulating materials are used for outer walls. For the same reason, not only the outer wall but also a window facing the outside of the building, etc., a glass double sash or a double glass called a pair glass has already been adopted. In addition, doors and sliding doors and other fittings facing the outside,
The same is true, already using insulating materials,
Some form doors and panels.

In this case, a panel such as a double glass or a heat-insulating plate-like body having a decorative aluminum plate on the inner and outer surfaces is provided around an aluminum outdoor frame and a resin indoor panel. With this structure, it is sandwiched by the frame and held inside the door, and by adopting this structure, the temperature difference between the indoor and outdoor, that is, the high temperature in summer and the low outdoor temperature in winter, is transmitted to the indoor side by aluminum with good heat conductivity. Is prevented from being done. At that time, the previous panel is formed by a holding member projecting toward the panel, called a beat made of soft resin formed on the indoor side frame.
It is fixed stably so as not to move.

[0004]

The fittings having the above-mentioned structure are excellent in terms of heat insulation based on the thermal conductivity of the material, and are excellent. However, this fitting was not originally designed with sufficient consideration for airtightness and watertightness. As a result, when heavy rain such as a typhoon blows the fittings from the side, water leakage may occur. It was found that airtightness and watertightness were not perfect.

Therefore, the present inventor paid attention to this problem,
The present invention has been researched and developed to solve this problem. That is, an object of the present invention is to provide a fitting such as a door having sufficient airtightness and watertightness. Particularly, the airtightness and the airtightness capable of sufficiently withstanding a special weather such as a typhoon. It is an object of the present invention to provide a fitting such as a door that can exhibit watertightness.

[0006]

A fitting adopted by the present invention to achieve the above object has a panel inside a door and a frame provided around the panel, and the frame is an outdoor frame. The panel is sandwiched between the two frames, and the airtight portion is substantially continuously interposed on almost all four sides between the facing portions of the indoor side frame and the outdoor side frame. It is characterized by the following. By adopting such a structure, the fitting of the present invention has excellent airtightness and watertightness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a fitting, particularly a door, of the present invention will be described in detail and concretely with reference to the drawings. FIG. 1 is a cross-sectional view illustrating the entire entrance door 1, in which a central portion thereof, that is, a portion of a panel 5 made of double glass is broken up and down and shortened. FIG. 2 is a longitudinal sectional view showing the entire entrance door 1, in which a central portion thereof, that is, a portion of a panel 5 made of double glass is cut horizontally and shortened.

This door comprises a door 2, a handle 3, and an outdoor frame 1.
1, an indoor side frame 20, an indoor side frame cover 15, a panel 5, and the like. In the illustrated door, the door body, the outdoor frame, the indoor frame and the indoor frame cover are each made of a heat insulating material, aluminum, synthetic resin, and wood or aluminum in order from the front,
The panel is made of double glazing, called a pair of glazings, which encloses dry air in the middle. The panel is sandwiched between the outdoor side frame and the indoor side frame, and its structure will be described in detail below.

The double glass, which is an example of the panel, has an outdoor glass 6 and an indoor glass 7, and has a heat insulating structure in which dry air is sealed in a space 8 therebetween. The panel is sandwiched between an outdoor frame 11 surrounding four rounds and an indoor frame 20, and is held by the door body 2 by connecting both frames. The connection is performed by screwing a screw 24 from the indoor side of the indoor side frame into a groove 13 that opens to the indoor side formed at the panel side end of the outdoor side frame. As a result, the holding portion 21 made of a soft resin called a beat formed on the indoor side frame and the holding portion of the outdoor side frame,
The panel is stably fixed so as not to move in the front direction. The holding tool 9 is also provided in the side surface direction of the panel, thereby suppressing the movement of the panel in the side surface direction.

The holding member 21 is used to stably fix the panel 5 originally. However, since the holding member 21 is formed of a flexible resin, the holding member 21 comes into close contact with the panel, and as a result, the panel 5 It has a structure that can also maintain the airtightness between the inner side frame 20 and the indoor side frame 20. In the present invention, not only that,
Further, in order to complete the airtightness and the watertightness between the two frames, an airtight portion 22 is formed between the facing portions of the indoor and outside frames and the indoor side frame 20, which is a feature of the present invention. is there.

The illustrated structure for that is as follows. That is, the indoor-outside frame 11 and the indoor-side frame 20
Abuts along the longitudinal direction of both frames, and at the abutting portion, both ends 12 on the indoor side of a portion forming the groove 13 of the outdoor frame 11 have a flange shape. In the portion, two narrow band-shaped airtight portions 22 made of a soft resin are formed in the indoor side frame 20 along the longitudinal direction of the same frame.

In the conventional indoor side frame 20, the contact surfaces of the two frames are made of a hard material, and the airtightness in this portion is not considered. As a result, the airtightness and the watertightness are insufficient. It was incomplete. The present invention has improved this point by adopting the above-described structure, and thereby completes the airtightness and watertightness between the opposing portions of both frames, particularly, the abutting / joining portions. The structure of the indoor side frame will be described in further detail. A thin band-shaped contact member 26 made of a flexible resin also exists on a contact surface of the door body side end surface with the door body 2. Thereby, it is stably attached to the door body and attached.

The interior side frame 20 is not integrally formed as a whole, but as shown in FIG.
And a horizontal member 32 in the form of a hollow plate are engaged with each other via a coupling 33 and assembled. The engagement is performed by engaging a claw (not shown) protruding from the coupling member 33 formed of a square plate-like member between the indoor side frame 20 and the indoor side frame cover 15 described later formed on both members. This is performed by engaging the groove 23 formed in the mating portion, and as a result, a rectangle surrounding the four circumferences of the panel is formed.

The vertical and horizontal members have a thin band-shaped airtight portion 22 for maintaining the above-mentioned airtightness and watertightness. The coupling member 33 has this shape, that is, the thin band-shaped airtight portion 22. It is not present, and instead, a synthetic resin having extremely high flexibility is present on almost the entire surface 34 (that is, except for the contact surface with the door body) and covers it. Airtightness and the like can be maintained.

An interior frame cover 15 having an excellent design is attached to the interior frame. The attachment structure is as follows. That is, the indoor side frame 2
The shape of the position at which the screw 24 is screwed when the screw 24 is connected to the outdoor frame is a groove 23, and the groove is provided with a claw 25 extending toward the indoor side. On the other hand, a U-shaped engaging member 16 having a claw 17 extending to the indoor side frame side at a position facing the frame cover 15 is also connected to the frame cover 15 by screwing. Both have a structure which can be joined by engaging these claws. Therefore, after arranging the indoor side frame cover 16 at a corresponding position of the indoor side frame 20, it is necessary to strongly press the former. Can be simply combined and integrated.

In the present invention, the exterior frame is made of a structure having excellent design properties made of aluminum, the door body is provided with a heat insulating structure in which a heat insulating material is inserted, and the panel is provided with double glass or a heat insulating material. It is desirable to adopt a heat-insulating structure, and to adopt a synthetic resin structure having a cover with excellent design for the indoor side frame. And in that case, while having the airtightness and the watertightness which are the excellent effects of the present invention, the design is also excellent, and the outside air temperature is high from the aluminum outdoor frame or the door body. Heat transfer to the indoor side can be blocked, and the fitting itself can have a structure excellent in heat insulation. Also, outdoor frame,
As for the material of the door body, the panel, and the indoor side frame, the above-described materials are preferable, but the materials are not limited thereto, and appropriate materials can be adopted as long as they do not deviate from the scope described in the claims. Needless to say.

According to the present invention, as described above, an airtight portion made of a flexible material made of a soft resin or the like is formed between the opposing portions of the indoor side frame and the outdoor side surface, particularly at the abutting portions of the two frames. Although it is characterized in particular, the shape of the airtight portion is preferably made of two thin strips at positions on both sides of the screw as specifically shown, but is not limited thereto. A single thin band may be used. Further, instead of the narrow band as shown in the figure, a band having a wide width such as two narrow bands and an intermediate portion thereof may be used.

And also about the position where it is formed,
It is not limited to extending over both sides of the screw. In short, the shape and position of the frame may be any as long as the airtightness and the watertightness can be maintained by forming an airtight portion at and near the abutting portion of both frames. Furthermore, referring to the installation position of the hermetic part, the target member for installing the hermetic part may be installed not only on the indoor picture frame specifically shown in the drawing but also on the outdoor picture frame. May be installed in both. Furthermore, instead of being connected to one of the two frames and being installed integrally, it may be merely sandwiched between the two frames. The point is that an airtight portion that can maintain airtightness and watertightness may be interposed between both frames. It is preferable that the hermetic portion is formed without a break over the entire periphery of the panel. However, even if a part of the hermetic portion is missing, it is acceptable as long as the hermeticity and watertightness can be maintained to a considerable extent.

As for the structure of the connecting portion between the vertical member and the horizontal member, it is preferable to use the above-mentioned connecting member, but the present invention is not limited to this structure. Of course, other known structures can also be employed. For example, the angle of both ends of both members may be set to 45 degrees, and the two members may be joined by abutting each other. Further, as for the airtight structure formed in the coupler, the illustrated structure is preferable from the viewpoint of manufacturing and the like, but is not limited thereto. For example, the same structure as that formed on both the vertical and horizontal members may be used. In addition, if it takes too much time to form a hermetic part in this part by adopting another coupling structure, even if it is omitted, there is no problem with extreme decrease in hermeticity and the like.

[0020]

According to the present invention, the airtight portion and the airtight portion are interposed substantially continuously around the entire periphery of the panel between the facing portions of the outdoor side frame and the indoor side frame, so that the airtightness and the watertightness are improved. Excellent fittings such as doors and sliding doors can be provided.
