The rods 25, 25 are slidably inserted, and the ends of these connecting rods 25, 25 and the handle shaft 23 are connected to the handle shaft 23, such as a pinion rack mechanism, a crank mechanism, etc.
The connecting rods 25 and 25 are connected via a mechanism that converts their reciprocating rotation into vertical linear motion of the connecting rods 25 and 25, and the connecting rods 25 and 25 are connected via a mechanism that converts the vertical linear motion of the connecting rods into horizontal linear motion, as shown in Figures 4 and 5. An interlocking pin 4 protrudes horizontally toward the vertical frame 4 at the lower end of 25.
2, and a slider 44 is vertically slidably supported by a vertical guide bar 43 fixed to the side of the vertical frame 4.
A U-shaped locking metal fitting 45 to be engaged with the interlocking pin 42 is provided protrudingly on the side surface of the shoji of No. 4, and one end of an elastic material 26 such as a band-shaped steel plate is fixed to the lower surface of the locking metal fitting. The plate 26 is passed through an arcuate L-shaped sheath 27 and extended onto the lower frame 3 in parallel thereto, and a slide piece 28 is connected to the extended end.

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. When the shoji is closed and the movable tight material 19 is in contact with the tight material 14 of the shoji as shown in the figure, looking at the movable tight material next to the lower frame, turn the handle 22 to raise the connecting rod 25. and interlocking pin 4
2 raises the locking metal fitting 45 and pulls the elastic plate 26 upward, and the slide piece 2 is pulled by this elastic plate 26.

The tight material 19 is lowered into the lower tight material 14.
and separate them. When the shoji 6 is rotated and opened in this state, the driven pin 42 separates from the locking metal fitting 45.

When the shoji 6 is rotated and closed, the driven pin 42 engages with the locking metal fitting 45, and when the handle 22 is turned to lower the connecting rod 25, the interlocking pin 42 lowers the locking metal fitting 45 and the elastic plate 26 is pushed downward, and the slide piece 28 is moved to the right in FIGS. 4 and 5 by being pushed by this elastic plate, whereby the movable tight member 19 is pressed against the lower tight member 14 in the opposite manner to the above.

When the movable tight material 19 is raised, the lower tight material 1

is pushed upward, thereby appropriately raising 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.
