- an outer frame, a static window, a joint axle,
- a bended axle;
- a left pinion and a right pinion;
- the sliding window comprising:
- a sliding frame, a sliding pane, a left rack, a right rack;
- wherein the sliding pane is made of transparent material and is configured to be framed within the sliding frame;
- the sliding frame is constructed from a left vertical sliding plank, a right vertical sliding plank, a lower horizontal sliding plank and an upper horizontal sliding plank;
- wherein the left rack is installed on an inner side of the left vertical sliding plank;
- wherein the right rack is installed on an inner side of the right vertical sliding plank;
- the static window comprising:
- a static frame, a static pane;
- wherein said static pane is made of transparent material and configured to be framed within said static frame;
- wherein the static frame is constructed from a left vertical static plank, a right vertical static plank, a lower horizontal static plank and an upper horizontal static plank;
- wherein the lower horizontal static plank has a recess which is configured to house the left pinion, the joint axle and the right pinion;
- the outer frame comprises:
- a left vertical guide, a right vertical guide, a lower horizontal outer bar and an upper horizontal outer bar;
- wherein said left vertical guide is parallel to the right vertical guide;
- wherein said left vertical guide is facing the right vertical guide;
- wherein the left vertical guide and the right vertical guide both include a first track and a second track;
- wherein the first track is parallel to the second track;
- wherein the first track is configured to guide the sliding frame in sliding up and down within the outer frame;
- wherein the static frame is installed in the second track;
- wherein a top side of the upper horizontal static plank is attached to a bottom side of the upper outer horizontal bar;
- wherein the joint axle is coupled with the left pinion at a joint axle left end;
- wherein the joint axle is coupled with the right pinion at a joint axle right end;
- wherein, turning the joint axle also turns the left pinion and the right pinion;
- wherein the left pinion is engaged with the left rack and the right pinion is engaged the right rack;
- wherein the right rack and the sliding frame are configured to being vertically moved by turning the right pinion;
- wherein the left rack and the sliding frame are configured to being vertically moved by turning the left pinion;
- wherein, a single turn of the left pinion is configured to displace the left rack by a unit left displacement;
- wherein, a single turn of the right pinion is configured to displace the right rack by a unit right displacement;
- wherein the unit right displacement is configured to be equal to the unit left displacement;
- wherein moving the sliding window up and down is facilitated by turning the joint axle;
- wherein the joint axle right end is coupled with a bended axle left end;
- wherein turning the bended axle is configured to turn the right pinion, the joint axle and the left pinion.
