BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raising / lowering window, and more particularly to a raising / lowering window for improving the mountability of a balancer.

[0002]

2. Description of the Prior Art A movable shoji is provided in a frame body composed of an upper frame, a lower frame and left and right vertical frames so as to be movable in the vertical direction, and a balancer capable of stopping the movable shoji at an arbitrary height position is provided in the vertical frame. The raising / lowering window provided in the window is, for example, the actual open sho 62-3.
It is already known from Japanese Patent No. 6181 and Japanese Patent Publication No. 4-17277. FIG. 6 is an indoor side front view showing an example of a conventional raising / lowering window, and FIG. 7 is an enlarged sectional view taken along the line BB of FIG. This raising / lowering window is provided with an outer shoji 2 as a fixed shovel in the upper part of a frame body 1 composed of an upper frame 1a, a lower frame 1c and left and right vertical frames 1c, 1c, and an inner shoji 3 is movable in the lower part of the frame body 1. It is provided as a shoji so that it can move vertically. And
In the vertical frame 1c, a nut 4 is urged to rotate by a spring force.
A screw type balancer 43 capable of stopping the inner shoji 3 at an arbitrary height position is attached via a screw plate 42 screwed to 1.

This screw type balancer 43 is composed of the vertical frame 1
A pipe 45 fixed from the inside by a mounting screw 44 is provided in an upper portion of a vertical groove 1c formed by opening inwardly in c, and a nut 41 is rotatably attached to a lower end portion of the pipe 45, Inside the pipe 45, a spiral spring (not shown) whose one end is connected to the nut 41 is attached. A slider 10 slidable in the vertical groove 7 of the vertical frame 1c is provided on a side portion of the inner screen 3, and the screw plate 42 is attached to the slider 10 in an upright state. It is screwed onto the nut 41 and inserted into the pipe 45 so as to be vertically movable. In addition, the vertical frame 1c has a crescent lock 17 attached to the upper end of the inner shoji 3.
A stopper 46 for restricting the upper limit position of the inner shoji 3 is attached so as to hide the mounting screw 44 of the pipe 45.

According to the raising / lowering window constructed as described above, the nut 41 is rotationally biased by the spring force of the spiral spring, thereby generating an urging force for screw-feeding the screw plate 42 upward. The inner shoji 3 can be stopped at an arbitrary height position by balancing the load of the inner shoji 3 with the force and the friction between the nut and the screw plate.

[0005]

However, due to the structure in which the screw-type balancer is used in the raising and lowering window, the frictional resistance between the nut and the screw plate is large. The opening and closing operations tended to become heavier as the load increased. On the other hand, as a balancer for raising and lowering windows, for example, Japanese Patent Laid-Open No. 8-135296
As described in the publication, there is known a wind-up balancer in which a movable shoji can be stopped at an arbitrary height position via a suspending member, for example, a wire which is biased by a spring force. This winding balancer includes a wire winding drum, a constant load spiral spring, and a power transmission mechanism, and thus has a low frictional resistance and makes it easier to open and close the movable shoji. Therefore, if a take-up type balancer can be attached instead of the screw type balancer, the raising / lowering window can be improved to have excellent operability.

However, since the winding balancer is constructed so as to be mounted in the upper frame,
Not only is it troublesome to install, but it is also necessary to form a through hole or groove for allowing the wire to penetrate therethrough. For this reason, it is difficult to attach a take-up balancer in place of the screw type balancer in the raising / lowering window having the screw type balancer.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a raising / lowering window in which a rewind type balancer can be easily attached and the workability and operability of the attachment can be improved. . Further, the object of the present invention is to
It is an object of the present invention to provide a raising / lowering window having a screw type balancer, which can be easily modified to a winding type balancer, and can be improved in operability.
