(2) At this time, the rotary damper rotates, unlike window frames that move in a straight line, so the damping effect is achieved by converting the kinetic energy generated while moving in a straight line into rotational motion, so the shock absorption is smooth and the shock absorption effect is increased. You can.

(3) In addition, when opening a window panel, the rotary damper, which was forcibly rotated when closing the window panel, rotates in the opposite direction and forcibly pushes out the window panel, so to maintain airtightness, the window panel that was tightly closed to the window frame is removed. It can be opened easily and conveniently by forcefully pushing it out.

(4) On the other hand, the rotary damper is equipped with a roller at the part that contacts the window frame, so that the direction in which the window frame moves straight and the direction in which the rotary damper rotates are different, preventing a sudden buffering action when closing the window frame, thereby creating a buffering effect. Let it happen naturally.

(5) The slider that catches the striker moves in a direction that intersects with the direction in which the window panel moves and pulls the striker into the body, so the window panel adheres firmly to the window frame, preventing foreign substances, dust, etc. from entering the room. Effectively blocks inflow.
