Description

[Detailed Description of the Invention] This invention relates to a tight material extension adjustment device in a movable tight device of the type that advances and retreats the tight material in a rotary window that rotates on a vertical axis or a horizontal axis.

The present applicant first proposed a movable structure in which a movable tight material is supported on a frame material perpendicular to the rotation axis of a shoji of a revolving window so as to be able to move forward and backward, and the tight material is moved forward and backward through an interlocking mechanism by operating a handle. I applied for a tight device.

This proposal addresses the unevenness of the gap between the shoji and the window frame that should be sealed, and the increase and decrease in the gap due to use.
The present invention provides a tight material extension adjustment device in a movable tight device that can maintain a required tightening effect by adjusting the extension of the tight material. The details of the present invention will be explained below with reference to the drawings.

In FIG. 1, a shoji 6 consisting of upper and lower frames 7 and a and left and right vertical frames 9 and 10 is installed vertically on a window frame 1 consisting of upper and lower frames 2 and 3 and left and right vertical frames 4 and 5. Rotating axis 1
It is rotatably supported by 1 and 11. 12
is the glass of the shoji.

On the indoor side of the upper and lower frames 2 and 3 of the window frame 1, there is a tight material receptacle 13 with a U-shaped cross section that opens across the shoji (the upper frame is not shown) as shown in the second figure.
A belt-like tight material 14 running through the length is attached to this, and a third
As shown in the figure, tight material receivers 15, 15 with a C-shaped cross section that open across the shoji are provided, and longitudinal tight materials 16, 16 are attached to these. They are arranged in a series of frame shapes.

On the other hand, as shown in the second figure, the upper and lower tight materials 1 are placed on the interior side of the upper and lower frames 7 and 8 of the shoji 6.
4 and 14, a tight material guide groove 17 (the upper stile side is not shown) with a vertically U-shaped cross section and an appropriate depth that opens on both sides of the upper and lower tight materials is provided protrudingly. A vertically elongated tight material holder 18 is fitted so as to be vertically slidable, and a longitudinally extending movable tight material 19 is attached to the holder 18 to be brought into contact with and separated from the upper and lower tight materials 14, 14. Reference numerals 20 and 20 denote longitudinal abutment flanges protruding from the interior side of the room facing the left and right vertical frames 9 and 10 of the shoji. When the shoji is closed, one of the abutment flanges 20 is attached to the left tight member 16 of the window frame. On the side of the room,
The other abutting flange 21 abuts against the outdoor side surface of the right tight member 16.

The drive mechanism for moving the movable tight member 19 up and down includes an interlocking mechanism that interlocks a slide piece (to be described later) by operating a handle, and a cam mechanism. For convenience, the drive mechanism for the upper and lower frames will be explained. A handle 22 (Fig. 2) is attached to an intermediate position of a hollow part H (Fig. 3) extending in the longitudinal direction in the left vertical stile 9 of the shoji, and the shaft 23 of the handle penetrates into the hollow part H. Connecting rods 25, 25 extending upward and downward from a position close to the handle shaft 23 are slidably inserted into a guide groove 24 which is provided adjacent to the hollow portion H and has a substantially C-shaped cross section and extends in the longitudinal direction. , the ends of these connecting rods 25, 25 and the handle shaft 23 are connected to a means such as a pinion rack mechanism, a crank mechanism, etc. for converting the reciprocating rotation of the handle shaft 23 into vertical linear movement of the connecting rods 25, 25. A fourth,
5. As shown in the figure, one end of the elastic plate 26, such as a belt-shaped steel plate, is fixed, and the elastic plate 26 is attached to the arc-shaped L-shaped sheath 2.
7 and extends laterally behind and parallel to the tight material guide groove 17, and a slide piece 2 is provided at the extending end.
It is connected to 8.

The slide piece 28 has a protrusion adjustment screw rod 32 rotatably supported through the opposing side plates 30 and 31 of a substantially flat U-shaped frame 29, with its head 33 exposed outside the side plate 30. Between the side plates 30 and 31, a block 34 having an inclined groove cam 35 on the side surface is screwed through the threaded rod 32, and as the threaded rod 32 rotates, the block 34
can be moved between the side plates 30 and 31, and the slide piece 28 is connected to a pair of guides having an L-shaped cross section and extending in the lateral direction provided on the outer surface of one side wall 17' of the tight material guide groove 17. Rail 36, 36
At the same time, a driven pin 37 protruding from one side of the tight material holder 18 is passed through a longitudinal long hole 38 (FIG. 4) formed in the side wall 17' of the tight material guide groove. and is engaged within the grooved cam 35. Reference numeral 39 denotes a connecting pin protruding from the back surface of the slide piece 28, to which the elastic plate 26 is connected. Another slide piece 28' having substantially the same structure as the above-mentioned slide piece 28 is arranged on the right side of the shoji in the same manner as described above, and both of these slide pieces are connected to the connecting rod 4.
They are connected by 0. 41 is the sheath 2 of the elastic plate
This is a bracket that holds 7.

The drive mechanism for moving the movable tight member of the upper stile of the shoji up and down is also substantially the same as that described above.

The operation of this device is as follows. As shown in the figure, the shoji is closed and the movable tight material 19 is moved to the tight material 1.
4, when the movable tight material on the lower side of the stile is turned, when the handle 22 is turned to raise the connecting rod 25, the slide piece 28 is pulled by the elastic plate 26 and moved onto the guide rails 36, 36. Move to the left in Figures 4 and 5 along the block 34.
The grooved cam 35 pushes the driven pin 37 upward along the elongated hole 38, thereby pushing the tight material holder 1.
8 rises within the guide groove 17 and separates the tight material 19 from the lower tight material 14.

When the movable tight material 19 descends, the lower tight material 1
4, by turning the head 33 of the protrusion adjusting screw rod 32 of the slide piece 28 with a screwdriver, move the block 34 to the right in FIG. Push it downward, thereby appropriately lowering the tight material holder 18 and increasing the protrusion of the movable tight material 19.

One end of the entire movable tight material 19 is in pressure contact with the lower tight material 14, but if the other end creates a gap with the lower tight material 14, adjust the adjustment screws of the left and right slide pieces 28, 28'. Turn the rod 32 to adjust the left and right protrusion of the movable tight member 19.

As another embodiment of the present invention, the grooved cam 35 in the above example is provided in the tight material holder 18, the driven pin 37 is provided in the block 34, and the driven pin 37 is provided in a horizontal elongated hole formed in the guide groove side wall 17'. It is also possible to provide another guide that penetrates through and engages with the grooved cam, while moving the tight material holder 18 only up and down within the guide groove 17, and the other structure is substantially the same as the above example. It will be done.

According to this invention, the protrusion of the movable tight material in the tight direction can be adjusted by operating the protrusion adjustment member, thereby ensuring that there is no gap between the shoji and the window frame that should be sealed with the movable tight material. It is very convenient to use because it can be adjusted to maintain the required seal even when the gap becomes uniform or increases or decreases with use.
