Abstract

PURPOSE:To obviate a cover so as to reduce the cost by journalling a pulley to the position of meeting rails at the time of an inner sash and an outer sash being both in the closed state, and covering the pulley with the meeting rail of the inner sash and a stile in the opening/closing state of both sashes. CONSTITUTION:A shaft is connected to a wire 4 hung around a pulley 3 journalled to a longitudinal frame 5 toward the depth direction of the longitudinal frame 5, and an inner sash 1 and an outer sash 2 are both elevated along the longitudinal frame 5 in the mutually balanced state through the pulley 3. In this case, the pulley 3 is journalled to the position of meeting rails 11, 21 at the time of both the inner sash 1 and outer sash 2 being in the closed state, and at the opening/closing time of both sashes 1, 2, the pulley 3 is covered with the meeting rails 11 and a stile 12. One end position, connected to the sashes 1, 2, of the wire 4 is connected to the stile 12 in addition to the lower rail, and the connecting position to the stile 12 is changed to cope with the height dimension change of the sashes 1, 2.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raising / lowering window having an inner shoji and an outer shoji which are opened and closed in conjunction with each other.

[0002]

2. Description of the Related Art An opening / closing mechanism for a raising / lowering window accommodating an internal shoji and an external shoji that interlocks with each other along a vertical frame has a rack and pinion structure as in Japanese Utility Model Sho 63-45498. There are two types, one is the method of using the pulley and the wire as in Japanese Utility Model Publication No. Sho 59-21251.However, when the former method is used alone, each load of the internal shoji and external shoji is part of the tooth of the pinion. Therefore, when the shoji has a large load, such as when accommodating double glazing, the tooth load becomes large and there is a fear of damage.

In the latter method, since the shoji is supported by the tension of the wire, there is no problem of breakage, but for the purpose of increasing the amount of raising and lowering the shoji with respect to the height of the shoji, the pulley is conventionally used as in Japanese Utility Model Publication No. Sho 59-21251. Is located above the shoji that closes downward with both shoji closed, so that the pulley is exposed to the inside of the room with both shoji closed. In order to avoid exposing the pulley, it is necessary to install a cover in the vertical frame, which causes an increase in cost.

Further, in the above example, since both ends of the wire are connected to the lower frame of the shoji, in order to cope with the change in the height of the shoji while keeping the length of the wire constant, the axial support position of the pulley must be changed. It is troublesome.

The present invention has been made by paying attention to the problem of a conventional raising / lowering window using a pulley and a wire, and proposes a raising / lowering window which does not expose the pulley.

[0006]

According to the present invention, when the inner shoji and the outer shoji are both closed, the sheaves are opened by pivotally supporting the pulley at the position of the summing frame which overlaps each other in the prospective direction. The pulley is covered with the inner frame and the vertical frame of the sliding door in any of the closed states, and the cover for covering the pulley is unnecessary.

Further, since the connection position of one end of the wire to the shoji is not limited to the lower frame, the wire length and the axial support position of the pulley are kept constant when the height of the shoji changes. One of the two ends is connected to the vertical frame, and the position is changed. Especially when the height of the shoji is large, it is possible to keep the wire length constant by changing the pivotal support position of the pulley and the connection position of one end of the wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, the raising and lowering window of the present invention is connected to a wire 4 which is hooked on a pulley 3 which is pivotally supported by the vertical frame 5 with its axis facing the direction of finding the vertical frame 5. The inner shoji screen 1 and the outer shoji screen 2 move up and down along the vertical frames 5 and 5 while maintaining equilibrium with each other.

The pulley 3 is a summing frame 11, which overlaps each other in the prospective direction when both the inner and outer shovels 1 and 2 are closed.
As shown in FIG. 3, the pulley 3 is pivotally supported at the position 21 and the pulley 3 is hidden from the indoor side by the summing frame 11 and the vertical frame 12 of the inner shoji 1 as shown in FIG. Since the inner shoji 1 is in a closed state and descended, the pulley 3 is hidden from the indoor side by the vertical frame 12 when the two shoji 1 and 2 are in a semi-open state or a fully opened state.

Both ends of the wire 4 are connected to the inner shoji screen 1 and the outer shoji screen 2, but one end is connected to one end as shown in FIG. In the embodiment, the position of the end of the wire 4 is connected to the shoji screen 2 in a finely adjustable state. This finely adjustable side end is stopped in a state where both shoji 1 and 2 are closed and there is no gap between the shoji and the lateral frame. At the fixed end, the fixing tool 6 connected to the wire 4 engages the receiving member 7 upward, and the receiving member 7 is fixed to the vertical frame 12 (22) and the lower frame 13 (summer frame 21). The fixing member 6 is engaged with the fixing member 6 and the receiving member 7 is fixedly connected by the vertical frame 22 (12) and the summing frame 21 (lower frame 13).
The height of the pulley 3 is freely adjustable by being connected to the screw 8 screwed on.

1 and 3 show a case where a screwdriver is used to adjust the position of the screw 8, and FIG. 4 shows a knob attached to the outer periphery of the screw 8.
An example of connection on the adjustment side when the position is directly adjusted by hand is shown.

In FIGS. 5 and 6, the fixed side of the wire 4 is attached to the inner shoji 1.
Fig. 7 and Fig. 8 show the fully closed state and the fully opened state when they are arranged near the lower frame 13, respectively. The closed state and the fully open state are shown. The receiving member 7 on the fixed side of the wire 4 is fixed to either the vertical frame 12 (22) or the lower frame 13 (summer frame 21), and does not necessarily have to be fixed to the lower frame 13 (summer frame 21). Therefore, for example, when the height dimensions of both shoji 1 and 2 are changed with respect to the same opening frame, the vertical frame of the receiving member 7 which is the fixed side of the wire 4 is not changed without changing the axial support position of the pulley 3. 12
It can be handled simply by changing the mounting position on (22). When the height of the opening frame changes, the pulley 3 is moved according to the length of the vertical frame 5.
By changing the shaft support position and the mounting position of the fixed side receiving member 7 to the vertical frame 12 (22), it is possible to cope with changes in the dimensions of the shoji 1 and 2 without changing the length of the wire 4.

[0013]

The present invention is as described above, and the pulley is
Since the inner shoji and outer shoji are pivotally supported at the position of the summing frame when both are in the closed state, the pulley is used as the summing frame for the inner shoji when the shoji are both open and closed. Since it can be covered with a vertical frame, the cover for covering the pulley is not required, and the cost for that can be reduced.

Further, the connecting position of one end of the wire to the shoji is not limited to the lower frame, but by connecting it to the vertical frame,
The height of the shoji can be changed by changing the connection position to the vertical frame while keeping the wire length and the pulley position of the pulley constant. By changing the position and the connection position of either end of the wire, it is possible to cope with the wire without changing its length.
