Description

[Detailed explanation of the idea] This invention relates to an improved double sash.

Conventional double sashes are those in which the inner sash for the inner sliding shoji and the outer sash for the outer sash are integrally molded, and the inner sash and outer sash are molded separately, and each sash is molded separately. There are two types that are bonded with a heat insulating material interposed between them.

Since the former is a one-piece structure, it can only be used as a double sash, and therefore it can only be installed on windows with a width that allows for the installation of a double sash. Requires dedicated large inventory space.

In addition, in the latter case, the inner sash and outer sash are separate bodies, but because the feeding structure with the insulation material interposed is a special shape provided on the inner and outer sashes, the inner sash and outer sash are always connected. They are used as a pair, and it is not suitable to use any one of them alone, and manufacturers still need to handle and inventory the inner and outer sashes by distinguishing them from the single sashes.

This idea was made with attention to the above points, and in a double sash where the inner sash and outer sash are molded separately, this inner sash can be improved by making only slight improvements to the inner sash. The sash can be easily attached to the conventional outer sash to form a highly insulated double sash, and it also reliably prevents water from entering from the joint between the outer sash and the lower frame of the inner sash. The purpose is to provide a double saturation that is made to be

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

In the figure, 1 is a wooden window frame that serves as a lintel, window sill, pillar, etc., and forms a window opening 2 of a building.

, Sl are outer sashes, and the upper frame S10. is made of a metal profile. The lower frame S12 and the vertical frame S13 are assembled and connected in a rectangular manner using screw holes and screws, etc., and the mounting edge 3 is formed so as to be continuous in the shape of a brim along a vertical plane common to each frame. Fit the outer sash into the window opening from the outdoor side so that it is in contact with the outdoor side of the window frame 1, drive the nail 4 into the window frame from the mounting edge 3, and screw the screw 5 from the base frame. It is screwed into the wooden window frame and fixed to the building.

In the outer sash S1, sliding shoji 6, 7 and, if necessary, a screen door 8 are slidably installed in the same manner as the outer sash of a normal double sash or a double sash.

Furthermore, in this invention, the outer sash S1 is provided with a contact edge 9 that continues in a rectangular manner along a common vertical plane at the indoor end.

In the illustrated embodiment, the abutting edge also serves as the indoor side hanging wall 10' forming the upper Azusa shoji guide groove 10, the weir wall 11 of the lower frame, and the projecting edge 12' forming the doorstop groove 12 of the vertical frame. .

S2 is an inner sash, and an upper frame S21.S2 is also made of a metal profile. The lower frame S22 and the vertical frame S23 are connected in a rectangular manner in the usual manner, and the sliding shoji 13, 14 is slidably erected as is well known.

Dovetail grooves 15 that open toward the outdoors are provided at the indoor end of the base frame constituting the inner sash, and each dovetail groove is made of rubber or plastic elastic material that protrudes toward the outdoor direction but is not breathable. A heat insulating material 16 is fitted.

The dovetail groove 15 and the heat insulating material 16 exist on a common vertical plane, and at least the heat insulating material 16 is continuous in a rectangular shape.

Such dovetail grooves and heat insulating material are provided at positions such that when the inner sash S2 is fitted into the window opening 2 from the indoor side, they come into contact with each contact edge 9 of the outer sash S1 that is already attached. It is being

With the above-described configuration, after the outer sash S1 is fitted and fixed in the window opening 2 as described above, the inner sash S1 is
is fitted from the indoor side, and with the heat insulating material 16 strongly pressed against the abutting edge 9 and brought into close contact, by screwing nails or screws 17 from the base frame of the inner sash S1 into the window wooden frame,
Fix the inner satsushi to the building.

This constitutes a double satsushi.

In conventional double sashes that separate the inside and outside sashes, the metal screws that connect the inside and outside sashes pass through the insulation material.
The screws became a heat conduction medium and the insulation properties were significantly impaired, but with this invention, the inner and outer sashes are completely isolated by the heat insulating material, and no metal members are used to connect the inner and outer sashes. has been improved.

In addition, since the outer sash S1 only has a rectangular continuous contact edge 9 along a common vertical plane at the indoor end,
Since it is almost the same as a conventional single-layer sash, only the outer sash can be used as a single-layer sash, and therefore manufacturers and tailors can sell only the outer sash separately.

Conventionally, in order to convert a window that previously had a single sash to a double sash, it was necessary to replace all the inner and outer sashes, but if the outer sash of this invention is installed, it can be converted into a double sash. To do this, simply purchase the inner sash, fit it into the window opening, press the insulation material against the abutting edge of the outer sash, and secure the inner sash.

Therefore, the cost of double sashing can be saved and construction is extremely simple.

In order to facilitate fixing to the window frame when the outer sash is used alone, the lower frame of the outer sash is provided with a fastening edge 3' that protrudes toward the interior of the room from its indoor end. .

Therefore, in this invention, the lower surface of the web of the lower frame S22 of the inner sash is attached so that the inner sash can be easily attached to the outer sash to form a double sash, regardless of the presence of the fastening edge. By providing the protruding support leg 31 at a position closer to the indoor side from the outdoor end of the lower frame by a distance greater than the protruding length of the fastening edge 3', the fastening to the lower side of the web is achieved. A gap 32 is formed excluding the edge 3'.

In addition, in double sashes, since dew condenses multiple times on the sliding shoji 13, 14 on the indoor side especially in winter, a large amount of water often accumulates on the upper surface of the lower frame S2□ of the inner sashes.

However, in this invention, a rising edge 33 is formed at the outdoor end of the web of the lower frame S22 of the inner sash, the dovetail groove 15 is provided at the upper end of this rising edge, and a heat insulating material 16 is provided in the dovetail groove. Although the heat insulating material is tightly attached to the outer sash weir wall 11, the water that has flowed down onto the upper surface of the lower frame of the inner sash as described above infiltrates into the window wooden frame from the joint between the inner and outer sashes. This is definitely prevented.

Figures 3 and 4 show an embodiment in which this invention is applied to a double sash for a bathroom, and the outer sash has the same basic components as those described above (the same symbols as above are used).
In addition to this, it integrally includes a lattice holding frame S3 consisting of a portion of the base frame extending toward the outside.

The lattice holding frame S3 is the upper frame S30. Lower frame S3□ and vertical frame S3
3, and the upper frame and lower frame are provided with locking edges 18° and 19 extending downward and upward at the outdoor end portions spaced from the contact edge 9 by an equal distance l in the outdoor direction.

Further, the locking edges 18, 1 are provided on the vertical frame S33 of the grid holding frame.
A fixed edge 20 is provided along a vertical plane common to window 9 and protrudes toward the center of the window.

Reference numeral 21 denotes a surface lattice, which consists of a large number of vertical lattices 24 on the outer surfaces of the upper and lower horizontal bars 22 and 23, the upper and lower ends of which extend upward and downward from each horizontal bar, and are fixed with screws 25. , the upper horizontal member 22 has a locking edge 27 forming a groove 26 that opens upward.
The lower horizontal crosspieces 23 each have a locking edge 29 forming a groove 28 opening downward. First, the surface lattice 21 is lifted and the locking edge of the lattice holding frame of the outer sash is inserted into the groove 26. 1
8, and then the lower horizontal bar 23 of the surface lattice.
When the surface grid 21 is brought into contact with the lower frame S3□, the locking edge 19 of the grid holding frame is fitted into the groove 28 of the lower horizontal crosspiece 23, and the surface is secured by the locking edges 18, 27 and 19.29. It is installed using the so-called Kendon method, prohibiting further downward movement and tilting of the grid, and screws 3 are inserted from the fixed edge 20 of the vertical frame S33.
0 are screwed into the vertical lattice 24 at both ends, and the panel lattice is attached to the window frame so that it cannot be removed from the outside.

Such a screen grid, which is easy to attach to bathroom windows and cannot be removed by unauthorized persons from outside, is suitable for construction and security reasons.

Furthermore, the inner sash S2 in this embodiment has the same basic components as those described above (indicated by the same reference numerals as those described above).

), an interior finishing frame S4 is provided at the indoor end.

That is, the interior finishing frame S4 is similar to the base frames S2□, S22.
．． It is composed of portions S4□ to S43 extending from S23 by an equal distance in the direction of the room, and the extension portion S4□ is sloped downward in the direction of the room to facilitate the flow of water droplets flowing down along the indoor side surface of the interior material 31. The lower extension part S42 is gradually inclined downward toward the room together with the lower frame S2□, making it easier for water droplets that have fallen from the shoji 13 and 14 to flow down to the bathroom floor and to sweep away dust that has adhered to the upper surface of the lower frame. ing.

32 is a water drain hole. 33 is a tile. Since each of the extension portions S4□, S42, and S43 receives the parting of the interior material, the interior finishing can be done very easily.

In double sash installed in bathroom windows, a large amount of dew condenses on the inner sliding shoji 13 and 14, and since the upper surface of the lower frame and the upper surface of the lower extension face into the room, it is necessary to occasionally remove dirt that accumulates on this upper surface with water. It is necessary to wash it with water.

In this invention, as described above, a rising edge 33 is formed at the outdoor end of the web of the lower frame of the inner sash, and a heat insulating material 16 is fitted to the upper end of the rising edge 33 to form a rising edge 33 on the weir wall 11 of the lower frame of the outer sash. Because they are pressed together, there is no risk of water seeping into the wooden window frame or the outer wall from the connection between the lower frames of the inner and outer sashes, even if a large amount of condensation water is generated or washing water is poured as described above. It is.

As described above, according to this invention, firstly, a rising edge is formed at the outdoor end of the web of the lower frame of the inner sash, a heat insulating material is fitted to the upper end of the rising edge, and the heat insulating material is fitted to the upper end of the rising edge. Since the material is placed in close contact with the indoor side of the lower frame of the outer sash, it is possible to clean the large amount of condensation that tends to occur from the inner sliding shoji of double sash, or the top surface of the lower frame of the inner sash when installed on a bathroom window. This prevents water from entering the window frame from the joint between the lower frame of the inner and outer sashes.

Second, on the lower surface of the web of the lower frame of the inner sash, a supporting leg is provided that projects from the indoor end of the lower frame of the outer sash and forms a gap excluding the fastening edge. Therefore, the inner sash can be easily attached to the outer sash which is provided with the fastening edge and can be used as a double sash to form a double sash.
