Claims

[Scope of utility model registration request]

A balancer biasing means in which a link mechanism that can be bent and expanded is interposed between the lower side of the elevating window main body and the fixed machine frame, and the link mechanism is biased in the direction of extension, or a window opening/closing device that expands and contracts the link mechanism. In an elevating window provided with a drive means for use, a spring is installed between two adjacent links in the link mechanism, and as the link mechanism expands and contracts, the springs move on both sides of an imaginary neutral line passing through the link pivot points. The link mechanism is interposed so that the spring action position is switched at , so that the biasing force of the spring extends the link mechanism only when the elevating window main body exceeds a fixed position near the upper limit of movement toward the upper limit of movement. It is configured to act in a direction to move the elevating window main body upward, and further configured to be able to adjust the position of one of the application points at both ends of the spring in a direction that can change the timing at which the direction of the urging force of the spring changes. A latch device for elevating windows.
