[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for retracting shoji sliding doors on wooden sashes such as entrances and windows.

[0002]

2. Description of the Related Art In a sash in which a sliding shoji is housed, a gap is inevitably formed between the connecting frames of the inner and outer sliding screens. Therefore, in the aluminum sash, L-shaped engaging pieces that are fitted to each other are integrally formed. Thus, when the shoji screen is tightened, the gap between the fitting frames is closed by both the engaging pieces. However, conventionally, in the wooden sash, the engagement frame has not been provided with such an engaging piece.

[0003]

[Problems to be solved by the invention] Therefore, in the wooden sash, there is a problem that outside air easily enters through the gap between both calling frames and lacks airtightness, and cold drafts are introduced in winter,
Especially in the present age when the air-conditioning system is fully equipped, it is necessary to ensure its efficiency, and this is one of the factors that hinder the spread of wooden sashes.

Even in a wooden sliding door, it is not always impossible to provide an L-shaped engaging piece on the assembly frame, but since the sectional structure is complicated, it is not easy to work, and the wooden piece Since it is brittle unlike metal such as aluminum, the engaging piece may be chipped.

It is also conceivable to separately manufacture the engaging piece from a metal such as aluminum and fix it to the joining surface of the joining frame by means such as screwing.

[0006] However, in the conventional wooden shoji, since the cross section of the fitting frame is rectangular, in this case, in order to make it project in an L shape, the engaging piece including the fixing portion, for example, Since it has to be formed into a complicated U-shape and is mounted so as to project from the fitting surface of the fitting frame, the mounting strength cannot be reliable. Further, it is necessary to provide an interval between both engagement frames in which both engagement pieces project and engage with each other, the airtightness is not always improved, and the engagement piece can be seen from the interval. There is a problem that the general appearance as a wooden sliding door cannot be maintained.

Originally, the wooden shoji paper has a gorgeous appearance due to the choice of materials, in combination with the natural beauty of the wood grain.
Not only can you feel the warmth of the wood, but because the thermal conductivity is much smaller than that of aluminum, it has excellent heat insulating properties, and even if it is completely dead, the wood breathes. It also has the characteristic of being healthy.

The present invention has been made in view of the above situation, and since a space between the fitting frames of the inner and outer sliding doors is sealed by a combination of the cross-sectional shape and another member, a gap is formed between them. It is a wooden piece that does not enter the wind, is easy to work on the joint frame, has a simple shape of another member, and has stable mounting, and can maintain its general appearance as a wooden shoji screen. The purpose of the invention is to provide a device for summoning a shoji shoji.

[0009]

[Means for Solving the Problems] A wooden sliding screen shoveling device according to the present invention for achieving the above-mentioned object is provided on the calling side of both shoring frames for inner and outer shoji screens, and is located slightly outside the width center. By providing a step on the side, a wide main side surface that is flush with the side surfaces of the upper and lower frames and a step protrusion that is adjacent to the main side surface of the other summing frame are formed, and the interval between both step protrusions is increased. Attach the tough band plate members to be sealed along the protruding surface of the tip,
When attaching the strip-shaped member, a low notched step surface for incorporating the strip-shaped member is provided on the projecting surface of the step projection, and the strip plate member is fixed to the notched step surface so as to be flush with the projecting surface.

[0010]

[Operation] When the sliding frame is tightened by tightening the sliding doors, the strip-shaped members on both sides seal between the step protrusions of both sliding frames, and there is double wind and rain between the step protrusions. Intrusion is blocked.

Not only is the shoring frame simple in structure and easy to work, but the main side surface of the shoring frame is flush with the side surfaces of the upper and lower frames when the shoji screen is viewed from the inside, and a normal wooden sliding shoji screen is used. Similarly, the calling frame is seen as having the same thickness as the upper and lower frames, and when viewed from the end, the step protrusion is seen as the thickness of the calling frame. It looks like a sliding shoji, and it is close to the other calling frame due to the step protrusion, and there is a slight gap between both calling frames as in the case of a normal wooden shoji, and the strip plate from that gap. Since the member is not visible, it is completely similar to a wooden shoji in appearance when it is installed.

Since the strip-shaped member is incorporated in and fixed to the stepped projecting portion at the low notch step surface, not only can the strength stability of the attachment be obtained, but it cannot be seen directly from the outside, even through the glass. Even if it looks like, it is easy to be seen as a part because it is flush with the step protrusion.

[0013]

Embodiments of the present invention will now be described with reference to the drawings. Although the drawing shows an example implemented in a wooden sash at the entrance, it can be similarly implemented in a wooden sash at a window.

The installation of the wooden sash is shown in FIG.
As shown in Fig. 4, there are four sliding screens 3 and 5 between the left and right columns 1 and 1 of the entrance and exit, and the central two sliding screens 3 and 3 are inside and the sliding screens 5 at both ends are 5 is on the outer side, and the adjacent inner and outer shoji screens 3, 5 are in a pulling relationship.

Therefore, each of the sliding shoji 3, 5 has a calling frame 7 on one side and upper and lower frames 11, 11 on the calling frame 7 and the other vertical frame 9.
It is a general framework in which the end faces of 13 are butted.

Like the other vertical frame 9, the combining frame 7 is abutted against the upper and lower frames 11, 13 at the same thickness. And on the calling side, the upper and lower frames 11,
By having the main side surface 14 that is flush with the side surface 16 of the reference numeral 13 and providing the step 17 on the outer side of the width center, a step protrusion 19 that is narrower than the main side surface 14 is formed.

The step projection 19 is a main side surface 1 of the other frame 7.
4 is projected until it comes close to 4, and when both calling frames 7 and 7 are brought together (FIG. 3), there is a space L between the step projections 19 and 19. In addition, the protruding tip surface 20 of the step protrusion 19
A low notch step surface 28 is formed by notching so that the step 17 side becomes low, the strip plate member 25 is fixed to the notch step surface 28 with a screw 27, and the outer surface is the protruding tip surface of the step protrusion 19. It is flush with 20.

The strip-shaped member 25 is a strip of aluminum alloy having substantially the same length as that of the fitting frame 7, and is wider than the width of the notched step surface 28, and the tip thereof is a step protrusion of the other fitting frame 7. When hitting the part 19, both calling frames 7 and 7 are correctly called. However, even if it does not abut, it may be close (especially in the case of a two-pull shoji).

The shape of the strip-shaped member 25 does not need to be a perfect strip. For example, the step projection 19 is formed on the strip.
It is also possible that a piece that abuts the side surface of the step 17 is projected.

As shown in FIG. 4, the two shoji shoji 3 and 3 in the center are vertically aligned with each other, as shown in FIG.
A groove line 29 and a protrusion line 31 to be assembled with each other,
The tightness of the butt is improved.

The airtightness of the sliding shoji 3 and 5 is also improved, as shown in FIG.
Rails 37, 3 made of extruded aluminum alloy
9, rail engaging grooves 41, 43 are formed at both upper and lower ends, and a groove 45 for accommodating the upper ends of both the sliding doors 3, 5 is formed in the duck 33.

[0022]

Since the present invention is as described above, the following effects are remarkably exhibited. 1) When the shoji screen is tightened, the interlocking spaces of both the inner and outer sliding screens are securely sealed by the interaction between the step projections and the strip-shaped member attached to the step projections. It is very good and can surely prevent drafts from entering, and in combination with the characteristics of the wooden sliding door with excellent heat insulation, it is suitable for providing a wooden sash with better heat insulation than an aluminum sash.

2) The strip-shaped member is hidden behind the other shoji screen and is not directly visible, and the relationship between the upper and lower stiles and the mutual relationship between the stiles and frames is visually different from that of a normal wooden shoji screen. Not only that, the appearance of wood is maintained, but it is possible to provide a luxurious wooden sliding door at a low price because only the stepped portion is seen as a thick frame.

3) The cross-sectional structure of the siding frame is a simple structure having only step protrusions, is easy to work, and the structure of the band plate member is also simple, which is suitable for mass production of wooden shoji. In this respect as well, it is possible to provide at low cost.

4) The strip-shaped member is fixed to the step protrusion of the assembly frame by incorporating it into the stepped notch surface, and even if it is a separate member, the integration with the assembly frame is strong and stable. Since it also reinforces the stepped portion, there is no fear of chipping it out, and since the calling frame is reinforced along the longitudinal direction to some extent, it is a wooden crib with stable strength.
