Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an up / down window and a door with an up / down window, and more particularly to an up / down window and a door with an up / down window for improving operability.

[0002]

2. Description of the Related Art As a raising / lowering window attached to an opening of a building, a fixed shoji and a movable shoji which can be raised and lowered are provided in a four-peripheral frame composed of upper and lower frames and left and right vertical frames.
There is a known configuration in which a balancer that holds the movable shoji at an arbitrary height position is housed and arranged via a suspending member that is wound and urged by a spring force (for example, Japanese Patent Application Laid-Open No. 8-1352).
No. 96, etc.). The balancer has a winding unit that rotates around a vertical axis and winds a hanging member,
After the hanging member is pulled out from the winding portion toward the end of the upper frame, the hanging member is guided downward by a pulley (guide pulley) along the vertical frame to hold the movable shoji.

[0003] In particular, in the case of a balancer in which a spiral winding groove having a gradually reduced diameter is formed in the winding portion so that a constant tension acts on the suspension member from the start to the end of winding, the winding portion and the pulley When the distance between is short, the angle at which the suspending member intersects the winding groove with the pulley as a fulcrum increases, so that the hanging member emits a noise rubbing at the edge of the winding groove. A certain distance must be secured between the winding unit and the pulley.

[0004]

However, in the raising and lowering window having the above structure, the suspension member drawn from the winding portion of the balancer is guided downward through the pulley.
A large load is applied to the pulley to generate frictional resistance, which necessitates an increase in the opening / closing force of the movable shoji, resulting in poor operability. In addition, since it is necessary to secure a distance between the winding section and the pulley, it has been difficult to reduce the width of the up / down window.

The present invention has been made in view of the above circumstances, and eliminates a pulley that guides a suspension member downward from a winding portion of a balancer, reduces frictional resistance, improves operability, and reduces width. An object of the present invention is to provide an up-and-down window and a door with an up-and-down window that enable the manufacture of a small up-and-down window.
