Description

[Detailed explanation of the invention] This invention uses the inertia of the shoji when it is closed to automatically pull the shoji toward the room, creating an airtight effect between the shoji and the window frame. Regarding equipment.

This applicant fixes a guide piece to a window frame, and a sliding piece that comes into contact with the guide piece when the inner shoji is closed, to a shoji built in the window frame, and either the guide piece or the sliding piece By providing on one side an inclined surface that is inclined with respect to the movement direction of the inner shoji when it is closed and that applies a pulling force toward the interior of the room at the time of the collision, the inertia force when the shoji is closed is utilized. We have proposed a window shoji pulling device that automatically biases the shoji indoors or outdoors to bring the shoji into close contact with the window frame.

However, in the pulling devices proposed so far, the guide piece is placed at a position below each shoji on the bottom frame, for example between the rails of the bottom frame, and the sliding piece is placed at the lower end of the hollow part of the vertical stile of the shoji or Since they are installed in the downward opening grooves at both longitudinal ends of the lower stile, it is difficult to align them immediately before installation.
Not only is it difficult to install it in a narrow area in an appropriate position and condition, but the guide piece also obstructs sweeping out dirt and dust that have fallen between the rails.

In addition, since the guide pieces are installed in a narrow space between the top surface of the bottom frame and the bottom surface of the shoji, their size is naturally limited, so the impact that the guide pieces and sliding pieces receive when the shoji is closed The problem was that it could be destroyed by force.

Therefore, this invention can be easily attached to window frames and shoji screens, can be easily aligned, does not interfere with sweeping out dirt from the bottom frame, and has sufficient strength to withstand the impact force when closing. The aim is to provide a pulling device that can

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

The window frame F, which is formed into a rectangular frame by the upper frame 1, the lower frame 2, and the left and right vertical frames 3, 3', has a guide groove a provided on the lower surface of the upper frame.
l, bl, rail a2 protruding from the upper surface of the lower frame. b2 and grooves a3 provided on the opposing surfaces of the left and right vertical frames. b3. a
4. An inner shoji fitting part a and an outer shoji fitting part a constituted by b4 are provided, and an inner shoji 4 and an outer shoji 5 are provided in each shoji fitting part.
are slidably fitted and held.

If necessary, on the outdoor side of the outer shoji fitting part, a guide groove C1 formed on the lower surface of the upper azure, a rail C2 formed on the upper surface of the lower frame, and grooves A4 on the left and right vertical frames. A screen door fitting part C is provided, which is constituted by projecting edges C3 and C4 forming b4 and outdoor extension parts 03' and C4', and a screen door 6 is slidably fitted and held in the screen door fitting part. There is.

The pulling device according to this invention has a sliding piece A attached to a puller 8 of a joining frame 7 of an inner shoji 4, and a lower frame 2 attached at a position where it collides with the sliding piece A when the inner shoji is closed. The guide piece B is attached to the upper surface of the edge 14.

The puller 8 extends from the upper end of the rain flap 13 of the lower frame to above a mounting edge 14 formed to extend toward the indoor side.

In the example shown in FIG. 3, the sliding piece A has a cross-sectional shape in the horizontal direction, and its negative side 9 is in contact with the connecting edge 8a of the puller 8, and a hole (not shown) provided in the connecting edge is inserted into the sliding piece A. By screwing the screw inserted into the hole 10 provided on one side of the sliding piece A, or by screwing the screw inserted into the hole of the sliding piece into the connecting edge 8a, or by gluing it, the puller 8 can be attached. installed on.

A sliding surface A' is formed at the tip of the other side portion 11 of the sliding piece A, which is inclined obliquely toward the indoor direction toward the sliding direction of the inner shoji when closed, and faces toward the outside of the room.

The indoor side surface of the other side is in contact with the outdoor side surface of the handle edge 8b of the puller.

As a result, as will be described later, the puller 8 has the effect of reinforcing the sliding piece A against the impact exerted by the guide piece B on the sliding piece A when the window is closed.

In the illustrated example, the guide piece B has a trapezoidal horizontal section, and has a guide surface on the side surface of the room that is inclined obliquely toward the room toward the sliding direction of the shoji when closed, and faces the inside of the room. B
'have.

Then, insert the screw S through the hole 12 penetrating in the vertical direction, pass through the mounting edge 14 provided at the upper end of the rain cover 13 of the lower frame 2, and screw it into the window sill (not shown). As a result, the guide piece is fixed to the lower frame at a position where it collides with the sliding piece A just before the inner sash is completely closed.

With the above-described configuration, when the inner and outer shoji 4 and 5 are closed,
Immediately before complete closing, the sliding surface A' of the sliding piece A attached to the puller 8 of the inner shoji 4 collides with the guide surface B' of the guide piece B, so that the lower side of the matching stile 7 of the inner shoji 4 part is subjected to a biasing force in the direction of the room.

When the door is completely closed, the amount of deviation in the indoor direction becomes maximum.

Therefore, the airtight material 16 attached to the indoor side surface of the lower stile 15 of the inner shoji is tightly pressed against the outdoor side surface of the rain cover 13 of the lower frame.

As described above, according to this invention, the sliding piece A is attached to the puller 8, and the guide piece B is attached to the mounting edge 14 at the position where it collides with the sliding piece A immediately before complete closing, so that the installation can be done without any space. can be made large, and therefore,
It is easy to attach to the puller and the lower frame, and while the guide piece B can be positioned with the inner sash closed, appropriate attachment can be easily carried out.

In addition, the dimensions of the sliding piece and the guide piece can be made relatively large, and the height dimension in particular is not limited, so that the sliding piece and the guide piece can be made with enough material to gather against the impact when the window is closed. It can have different thickness and height.

Also, rain return 13, rail a2. Since there is no need to install it in a narrow groove formed by b2 etc., dirt, dust, etc. that have fallen into the groove can be easily cleaned along the rail or washed away with water.

As mentioned above, the pulling device according to this invention only applies a biasing force in the direction of the room to the lower part of the sliding stile 7 of the inner shoji, so this device alone cannot provide a sufficient airtight effect for the entire window. I can't get it.

Therefore, in reality, other attracting means are used in combination, as will be described later.

That is, as for the upper part of the inner shoji 4, as shown in FIG.
The guide member B2 is attached at a position corresponding to both longitudinal ends of the upper stile 7, and the guide member B2 is attached to the upper end of the upper stile or the upper end of the joining stile 7 and the vertical stile 18 on the door stop side. An upper drawing means is provided which includes a sliding member A2 attached so as to abut against the guide surface B2' of B2.

The guide member B2 has a fixed part 19 that is bonded to the bottom of the guide groove a1 with an adhesive or fixed with a screw or the like, and is brought into contact with the indoor side surface of the partition wall 21 that forms the guide groove a1, and the inner shovel is closed. It integrally has a guide portion 20 having a guide surface B2' that is inclined obliquely toward the indoor side in the sliding direction.

In addition, the sliding member A2 is a hole (not shown) made in the upper stile 17.
Or a fixing part 22 that is inserted and fixed into the upper end of the hollow part of the stile 7 and the vertical stile 18, and a guide surface B of the guide member B2 that protrudes upward from the upper end surface of the inner sash and when the inner sash is closed.
2' and a sliding portion 23 having a sliding surface A2' that abuts against the sliding surface A2'.

In this way, when the inner shoji 4 is closed, the sliding surface A'
slides along the guide surface B2', the upper part of the inner shoji is biased toward the outdoors, and the airtight material 2 attached to the upper stile 17
4 is pressed into close contact with the indoor side surface of the partition wall 21.

In addition, pulling members C1 each having a cross-sectional shape of a letter L are fixed to the indoor side of the doorstop groove a4 of the inner shoji screen at appropriate intervals in the vertical direction.

This member has a guide surface 01' that is inclined diagonally toward the outside of the room toward the sliding direction of the inner sash when it is closed.

As a result, when the inner shoji is completely closed, the vertical stile 18 is also deflected toward the outside over its entire length, so that the vertical stile 1
The outdoor side surface of the partition wall 25 is tightly pressed against the airtight material 26 attached to the indoor side surface of the partition wall 25.

So far, we have explained the inner shoji, but also for the outer shoji 5, the guide member B2 of the upper drawing means mentioned above is attached to the guide groove b1, and the sliding member A2 is attached to the upper end of the outer shoji, and the outer shoji 5 is When the shoji is closed, the upper part of the outer shoji is biased toward the room, and a pulling member C2 similar to the pulling member C1 is attached to the outer shoji door stopper groove b3, so that the upper part of the outer shoji is biased toward the room when the shoji is closed. The stile 26' is biased towards the interior of the room.

Therefore, the airtight material 27 attached to the indoor side of the upper stile is
The airtight material 29 is attached to the outdoor side of the partition wall 21 of the vertical frame 3, and the indoor side of the vertical frame 26 is attached to the outdoor side of the partition wall 28 of the vertical frame 3.
Press and adhere to each.

Further, on the inside of the smoke return 31 of the joining frame 30 of the outer shoji, there is a pulling member C3 that is inclined toward the indoor direction in the sliding direction when the outer shoji is closed and has a guide surface facing the outdoor side. Since it is fixed, when the inner and outer shoji are completely closed, the tip of the chimney return 32 of the inner shoji collides with the guide surface of the drawing member C3, and draws the outer and inner stile 30 to the inner and outer stile 7.

Therefore, the airtight material 3 that is attached to the indoor side of the external frame
3 and 34 are pressed tightly against the outdoor side surface of the inner frame 7.

As described above, the lower part of the inner sliding stile 7 is pulled toward the room by the pulling device of this invention, and the lower part of the outer shoji is also pulled toward the room.

Therefore, the airtight material 3 installed on the indoor side of the outer shoji lower stile
5 is pressed into close contact with the stepped portion 36 of the lower frame 2.

In this way, by completely closing the inner and outer shoji of the illustrated window and locking the crescent lock 37, high airtightness and sound insulation can be maintained around each shoji, between the window frame, and at the joint. .

The sliding piece A and the guide piece B constituting the pulling device according to this invention are not limited to the shape shown in FIG. 3.

The sliding piece A has a sliding surface A' and can be fixed to the pull bar 8, and the guide piece B can also be fixed to the indoor side of the lower frame 2 than the rain cover 13, so that it can be fixed just before the inner shoji is completely closed. As long as it has a guide surface B' that abuts against the sliding surface, it may have any shape convenient for attachment depending on the shape of the pull bar.

The sliding surface and the guide surface may both be inclined with respect to the sliding direction when the sash is closed, as in the illustrated example, but if at least one of them is an inclined surface, the other is, for example, a convex surface. Even with curved surfaces, the desired effect can be obtained.

Further, the upper part pulling means for the inner and outer shoji, the door stop side pulling member for each shoji, and the pulling member for the stile are merely examples.

As mentioned above, the pulling device according to this invention consists of a sliding piece fixed to the pull bar and a guide piece fixed to the indoor side of the lower frame rather than the rain cover, so it is very easy to install. Easy and accurate positioning.

Further, the sliding piece has a shape that can be fixed to the pull bar, the guide piece has a shape that can be fixed to the mounting edge of the lower frame, and at least one of the sliding piece and the guide piece is arranged to close the inner sash. The structure is simple and easy to manufacture because the sliding piece has an inclined surface that is inclined with respect to the direction of movement, and just before the inner shoji is completely closed, it collides with the other side and guides and slides the sliding piece in the direction of the room. It is.

Furthermore, since the sliding piece is attached to the pull bar and the guide piece is attached to the mounting edge of the indoor side part rather than the rain cover of the lower frame, the sliding piece and the guide piece can have relatively large wall thickness and height. Therefore, it has sufficient mechanical strength to withstand the impact force when closing the shoji screen.

Furthermore, since it is not installed between the rails like in the past, it does not interfere with the removal of dirt and rainwater.
