Description

[Detailed description of the invention] This invention relates to a shoji frame that prevents dew condensation from forming on the side surfaces of a room.

Metal shoji frames have a high coefficient of thermal conductivity, so condensation tends to form on the sides of the room.

In order to prevent this, a shoji frame has been proposed in which the metal frame body is covered with a cover plate made of a synthetic resin material with a small coefficient of thermal conductivity. The installation structure is complicated and requires special and expensive manufacturing equipment, the resulting stile has strength problems, and the structure of the stile makes it difficult to install airtight materials. Things are not being supplied.

In view of the above points, the object of this invention is to provide a shoji frame that is easy to manufacture, has sufficient strength, can be easily fitted with an airtight member, and can sufficiently prevent dew condensation.

Next, an embodiment of this invention will be described based on the drawings.

As shown in FIG. 1, the shoji frame according to this invention consists of a metal frame body A and a synthetic resin cover body B.

The frame body A has a structure that can provide the strength generally required for frames.

'f, that is, it integrally has the outdoor side wall 1, the indoor side wall 2, and at least one, preferably two, webs 3, 4 connecting these side walls, and both side walls 1.2 and one web. It has a glass fitting groove 5 formed by 4 and 4.

Furthermore, the stile main body A has a dovetail groove 6, which is newly added according to this invention, on the side surface of the room, that is, on the side surface of the room on the indoor side wall 20, and opens toward the room over the entire length.

6a and 6b are locking edges that form the openings of the dovetail grooves.

On the other hand, the cover unit B is formed into a substantially thin plate shape as a whole by an outdoor side wall I and an indoor side wall 8 extending in parallel, and at least two webs 9 and 10 connecting these side walls. side walls 7.8 and web 9,
An intermediate section 11 is provided between the sections 10.

A protrusion 12 having protrusions 12a and 12b protruding in opposite force directions is integrally provided on the outdoor side wall γ.

The distance between the tips of these protrusions 12a and 12b is the length of the frame body A.
It is approximately equal to the width of the bottom of the dovetail groove 6.

Further, a groove 13 is formed near one end of the indoor side wall 80 in the width direction, and opens toward the indoor direction over the entire length.

This groove 13 is for attaching an airtight member 14 (described later) which is usually attached to a shoji in a metal sash. It is inserted into the groove 13 from one end in the longitudinal direction, and is fitted by sliding in the longitudinal direction.

Then, the cover unit B inserts the protrusions 12a and 12b at one end in the longitudinal direction into the dovetail groove 6 at one end in the longitudinal direction of the frame body A, and slides the cover unit with the longitudinal force of the frame body, The protrusions 12 are formed at the locking edges 6a and 6b.
By locking a and 12b, the cover is fitted onto the stile main body, and the indoor side surface of the stile main body is entirely covered with the seventh cover.

In this way, one shoji frame is constructed.

AB□ in FIG. 2 shows an example of one stile constructed as described above, and AB2 similarly shows an example of the lower stile.

15 is a bead attached to the periphery of the glass plate 160;
The locking edge 15a on the outdoor side of this bead is locked on the bent edge 1a formed at the end of the outdoor side wall 1 of the frame body A, and the locking edge 15b on the indoor side is locked on the web 9 of the cover integral B. It has been stopped.

By locking and covering the locking edge 15b on the indoor side of the bead 150 with the web 9 on the inner circumference side of the cover, the inner circumference of the cover is brought into closer contact with the frame body by the bead, Moreover, it is expected that the indoor wall of the stile body will be completely covered, thereby completely preventing dew condensation.

In addition, if the web 9 is made to protrude slightly toward the outdoors from the indoor wall 7 and the protruding portion is engaged with the inner circumferential end of the indoor wall 2 of the stile main body, the inner circumferential end of the integral cover will be connected to the stile main body. can be more reliably prevented from separating from the inner peripheral side end of the indoor wall.

To explain the effect of the above embodiment, since the frame body A is formed of the indoor and outdoor side walls 1.2 and the two webs 3 and 4, it becomes the mechanical main body of the frame and has sufficient strength.

In addition, the cover integrated B also has indoor and outdoor side walls 7.8 and web 9,
10 to form the hollow part 11, the cover has sufficient strength and can be firmly connected to the frame body even if the cover is attached by simply fitting it onto the frame body. The cover itself will not be damaged or warped by heat, wind pressure, etc.

Furthermore, since the hollow part 11 is provided, the heat effect between the indoor side surface of the stile body and the indoor side surface of the integral cover is very large.
There is no condensation on the interior side of the stile.

Furthermore, since the airtight member 14 is attached to the cover, even when the airtight member 14 protrudes toward the interior of the stile,
The metal part is not exposed on the indoor side, completely preventing dew condensation on the indoor side of the stile, and the shape of the stile body can be simplified.

The stile main body and the cover are integrally formed with a protrusion 12a in the dovetail groove 6,
Since it is attached by fitting the frame 12b, the frame body and the cover can be molded separately, and can be manufactured at low cost using ordinary simple manufacturing equipment. and cover can be combined.

As mentioned above, the shoji frame according to this invention is cheap and easy to manufacture, has sufficient strength, can be easily fitted with airtight members, and is completely prevented from condensation on the side surfaces of the room. There is.
