Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window frame, and more particularly to a window frame attached to an opening whose periphery is a true wall.

[0002]

BACKGROUND ART Conventionally, there are large walls that are often used in Western-style rooms and true walls that can be used in both Japanese-style rooms and Western-style rooms as interior walls of buildings, but most Western-style rooms are large walls, and true walls are used. It is often limited to Japanese-style rooms. Moreover, in recent years, when the number of Japanese-style rooms in the building is decreasing, the number of inner walls constructed with true walls is very small. Therefore, a window frame such as a sash window attached to the opening portion of the inner wall is designed on the assumption that the inner wall is a large wall. This is done by installing an attachment that is framed around the four sides on the indoor side. According to this, only one type of window frame is required, and it is not necessary to purposely manufacture a dedicated window frame for a small number of true walls, which is economical in terms of various costs.

[0003]

By the way, the conventional attachment is screwed to the window frame, but this screw is used at the position where the head is exposed. This is because even if the attachment needs to be replaced for some reason after the window frame is attached to the opening, the screw can be operated to facilitate the replacement work.

However, if the screws are exposed, the internal appearance is not good, and it is desired to reduce the number of screws. Further, if the number of screws is large, the work of exchanging the attachment becomes complicated, and from this point as well, there is a demand to reduce the number of screws.

An object of the present invention is to provide a window frame that can be made to look good and the attachment can be easily replaced.

[0006]

A window frame according to claim 1 of the present invention is a window frame assembled by arranging an upper frame, a lower frame, and left and right vertical frames around four frames, and the chamber of each frame. On the inner side, a finding piece protruding toward the building body side and a prospecting piece that is spaced apart from the building body side with respect to the finding piece and protrudes toward the indoor side are provided, and at least the prospective piece of the upper frame and the vertical frame. wherein between the building skeleton side, the upper frame and the vertical frame longitudinally continuous attachment is provided in at least one of the attachment is engaged with the base member fixed to the found pieces and , The above each frame
The inner side of the is the metal frame body and the resin that covers this frame body.
And a cover material made of
Is formed on the frame main body, and the prospective piece is made of the resin cover.
It is characterized in that the attachment is made of resin and the attachment is made of resin .

In such a structure, at least one of the attachments attached to the frame is engaged with the base member provided on the inner side of the frame, so that it is possible to use many screws unlike the conventional case. The attachment state of the frame and the attachment is reliably maintained, the number of screws is reduced, and the appearance is good. The base member is fixed to the fitting piece with a screw or the like, but such a screw is hidden by the attachment and therefore is not exposed and does not impair the appearance. Further, since the number of screws is reduced, the complexity of operating many screws is eliminated and the attachment can be easily replaced.

[0008] Then, because find pieces for fixing the base member is made of metal, it becomes what find piece has a large rigidity, the fixing strength of the base member increases. Further, since the indoor side of the frame is covered with the resin cover material, even if the metal part of the frame body is cooled by the outside air or the like, cold heat is not conducted to the surface of the cover material exposed to the indoor side and dew condensation occurs. It is hard to occur. Further, since the attachment arranged between such a resin-made prospective piece (cover material) and the building frame is also made of resin, the prospective piece and the attachment visually observed from the inside of the room have the same color and the like. The resin made of can be unified, and the designability is further improved.

In the window frame according to claim 2 of the present invention, the base member is provided in a piece shape, and a plurality of base members are arranged at intervals in the longitudinal direction of the frame. In such a configuration, since the base member is not continuous in the longitudinal direction of the frame, the contact resistance between the base member and the attachment is reduced, so that the attachment is easily engaged.

The cover member 132 is prevented from being deformed due to over-tightening. The screw 18 does not reach the pillar 4 and has a length sufficient to be screwed into the screwing portion 332.

The attachments 31, 32, 33 are engaged with the respective frames 11, 12, 13 as an attachment frame 30 which is a four-frame framework with screws (not shown). Further to the indoor side of such an attachment frame 30, except for a portion corresponding to the attachment 32, a gate-shaped frame 40 composed of an upper frame 41 made of split material and left and right vertical frames 42.
Is attached. Then, the window frame 10 is made compatible with a true wall by attaching the attachment frame 30, and when the attachment frame 30 is not provided, each prospective piece 14, 127, 134 is fixed to a plate-like frame on the side of the frame. For example, it is possible to deal with large walls.

In this embodiment as described above, the window frame 10 is installed in the opening portion of the building as follows. First, in a factory or the like, each frame body 111, 121, 131 is framed around four sides, and the cover members 112, 125, 132 are attached to this by engagement or screwing, and the window frame 10 is completed. Next, the base members 14, 15 and 16 are attached to the fitting pieces 113, 126 and 1 of the frame bodies 111, 121 and 131, respectively.
33 with screws and these attachments 31, 3
2, 33 are engaged. After this, the window frame 10 is attached to the shoji screen 2.
Deliver to the site with 0.

At the site, the upper frame 11 is attached to the lintel 2,
The lower frame 12 is screwed to the window stand 3 and the vertical frame 13 is screwed to the pillar 4. As one (one type) of these screws,
Using the long screw 17 shown in FIG. 8, the cover material 132 of the vertical frame 13 is fixed to the column 4 together with the attachment 33. After that, the shoji 20 is arranged in the window frame 10 via the hinge 26, and the vertical sliding window 1 is completed.

According to this embodiment, the following effects can be obtained. (1) Attachments 31, 3 attached to the window frame 10
Since the reference numerals 2, 33 are engaged with the base members 14, 15, 16 fixed to the frames 11, 12, 13, they are not fixed to the upper frame 11 and the lower frame 12 with screws or the like. Also, in the vertical frame 13, screws 1 are used to fix the cover member 132 to the attachment 33 at both ends and the center.
Only 7, 18 are used. Therefore, the window frame 1
As a whole, the number of screws to be visually recognized can be reduced as compared with the conventional one, and the appearance can be improved.

(2) For some reason, the attachment 31,
When it is necessary to replace 32 and 33, the upper frame 11 and the lower frame 12 are attached to the attachments 31 and 32.
It is only necessary to pull it out from the vertical frame 13, and with respect to the attachment 33, it takes a little time to remove the screws 17 and 18, and after that, it can be pulled out from the vertical frame 13, and when the new attachments 31, 32 and 33 are assembled. Similarly, since they can be engaged with each other, the replacement work can be easily performed because the number of screws to be operated is small.

(3) The base members 14, 15 and 16 have screws 115 and 1 on the metal parts of the frame bodies 111, 121 and 131, respectively.
Since it is fixed with 16, 118, screws 115, 11
The screwed portions of 6,118 are not damaged and loosened, and the base members 14, 15, 16 can be securely screwed, and the fixing strength can be improved.

(4) The cover members 112, 125, 132 for covering the interior sides of the frame bodies 111, 121, 131 are made of resin and have a heat insulating property.
Even when the cold heat due to the outside air is conducted to the indoor side of 131, it is not conducted to the surfaces of the cover members 112, 125, 132. Therefore, the temperature of the surface exposed in the room, that is, the surface temperature of the cover materials 112, 125, 132 does not decrease, and dew condensation can be effectively prevented. Particularly, in the lower frame 12, since the lower frame body 121 is formed of a heat insulating profile,
In general, even in the lower frame 12 portion where cold heat is easily conducted, heat conduction from the outside of the room can be reliably blocked, and the dew condensation performance can be markedly improved to prevent dew condensation more reliably.

(5) Since the cover members 112, 125, 132 and the attachments 31, 32, 33 are both made of resin, they can be molded by using resins of the same color.
Therefore, by unifying the colors, the appearance when viewed from the indoor side can be improved and the designability can be further improved.

(6) Since the base members 14, 15, 16 are short piece-shaped, long attachments 31, 3
Even when the two and 33 are engaged, the contact resistance is not so large, the engagement can be facilitated, and the workability is good.

(7) The cover member 132 of the vertical frame 13 is longer than the other members and easily floats on the indoor side.
The both ends and the center are attached by the attachment 33.
Since it is fixed to the cover member 132, it is possible to prevent the cover member 132 from rising and prevent a gap from being formed between the cover member 132 and the attachment 33, and there is no fear that the appearance will be impaired. The screws 17 and 18 are screwed into positions corresponding to the base member 16, and the base member 16 and the screwing portion 332 of the attachment 33 are interposed between the prospective piece 134 and the pillar 4. From the prospective piece 134 to these base members 16
And it can be supported by the attachment 33, and screws 17, 18
It is possible to prevent the cover material 132 from being deformed due to over tightening.

The present invention is not limited to the above embodiment. For example, in the above embodiment, all the attachments 31, 32, 33 are the base members 14, 1
Although it was attached to the frames 11, 12, and 13 via 5 and 16, at least any one of the attachments 31, 32 and 33 may be attached to the frame via the base member. Even in such a case, the number of screws can be reduced in the attachment portion attached via the base member as compared with the conventional case, and thus the object of the present invention can be achieved.

When the attachment is attached to the frame without using the base member, a horizontal screw may be screwed from the inside of the room so that the head of the screw hits the attachment, but the screw may be a little. In order to make it inconspicuous, it is desirable to screw the cover material so that the head of the screw hits the cover material like the screws 17 and 18 of the above-described embodiment. The attachment 31 for the upper frame 11 and the attachment 32 for the lower frame 12 screwed in this way
Is enlarged and shown in FIG. 9 and FIG.

In FIGS. 9 and 10, the frame bodies 111, 1
The base member is not fixed to the found pieces 113 and 126 of the attachment 21, and the attachment 31 arranged on the indoor side,
32 is a cover member 11 for these screwed portions 313, 324.
2, 125 are fixed by vertical screws 18 (also shown by a chain double-dashed line in FIG. 8) so that they cannot be separated from the frames 11 and 12. In such a configuration, the base members of the upper frame 11 and the lower frame 12 are omitted, so that the mounting work of the base member itself can be simplified. This is effective when the attachment frame 30 is not attached to the window frame 10 in advance at the factory as in the above-described embodiment, but is attached later at the construction site as an optional specification, and the base easily becomes complicated at the site. By simplifying the work of attaching the members, there is an effect that the work at the site can be performed quickly. Then, in such a case, the base member is provided only on the vertical frame 13, but at least on the vertical frame 13 side, the number of screws can be reduced as compared with the case where the base member is not used, The object of the present invention can be achieved.

Further, as in the above embodiment, the frame body 11
The base member 1 is attached to the found pieces 113 and 126 of 1,121.
Even when 4, 15 are fixed, a small number of screws 18 shown by the chain double-dashed line in FIG.
The prospective pieces 114, 127 of the attachments 31, 32
It may be fixed to the threaded portions 314 and 324. Even in such a case, if the number of screws in the vertical frame 13 can be reduced, it is included in the present invention. At this time, since the attachments 31 and 32 are reinforced vertically by the base members 14 and 15, if the positions of the base members 14 and 15 and the positions of the screws 18 are made to correspond to each other, the prospective piece 114, 1
27 to the attachments 31, 32 and the base member 1
4, 15 can be favorably supported, and the cover materials 112, 125 can be prevented from being deformed due to over-tightening of the screws 18.

In the above embodiment, the attachment 31,
Although all four circumferences of the window frame 10 are surrounded by using 32 and 33, a floor surface material is arranged immediately below the prospective piece 134 of the lower frame 12 like a terrace type window (sweep window), for example. In such a case, the attachment 3 for the lower frame 12
2 is omitted, and even if omitted, any of the remaining attachments 31 and 33 is included in the present invention as long as it is attached via the base members 14 and 16.

In the above-described embodiment, the window frame 10 is applied to the vertical sliding window 1, but the window frame of the present invention is not limited to the vertical sliding window, but the horizontal sliding window and the sliding window. For window frame of any window that is considered as a true wall, such as windows, dead-end windows, single-sided windows, double-sided windows, inward-facing windows, outward-facing windows, up / down windows, horizontal axis rotating windows, vertical axis rotating windows, louver windows, etc. Applicable.

In addition, the specifications relating to the heat insulating performance of the shoji arranged in the window frame are arbitrary. Further, the shape of the found piece, the prospective piece, or the like of the frame, or the shape of the attachment is arbitrary, and it may be appropriately determined in the implementation.
Furthermore, the material of each component is also arbitrary. For example, the cover material and the attachment exposed on the indoor side may be formed of a resin material containing wood powder, and the texture of natural wood can be obtained by doing so, so that the surrounding frame made of natural wood, Harmony with the lintel, window sill, and pillars improves the design.
