Operating hardware for a window complete comprising:
- an upper platform unit attached to a window frame, the upper platform unit comprising an upper platform base, an upper guide track, and an upper link arm mechanism configured to attach the upper link arm mechanism to a window sash;
- a lower platform unit attached to the window frame, the lower platform unit comprising a lower platform base, a first lower guide track, a second lower guide track wider than the first lower guide track, and a lower link arm mechanism, wherein the lower link arm mechanism is attached to the window sash;
- a sliding drive mechanism comprising a sliding housing base, a sliding housing top piece, a planetary gear set, and a worm and wheel gear set,
- wherein the planetary gear set is positioned between the sliding housing top piece and the sliding housing base,
- wherein the worm and wheel gear set comprises a wheel gear mounted to the planetary gear set, and a worm gear positioned between the sliding housing top piece and the sliding housing base and coupled to the wheel gear, and
- wherein the sliding housing top piece is secured to the sliding housing base;
- and
- a handle drive mechanism comprising an input bevel gear, a handle drive cap including a first hole for receiving the input bevel gear and a first half hole, an output drive gear, a handle drive base including a second hole for receiving the input bevel gear and a second half hole, and a handle drive shaft,
- wherein the output drive gear is mounted to the handle drive shaft and disposed within the first half hole and the second half hole;
- wherein the handle drive mechanism is mounted to the second lower guide track of the lower platform unit;
- and
- wherein the sliding drive mechanism is configured to freely slide within the second lower guide track of the lower platform unit.
Operating hardware for a window complete for transition between three modes including an operation mode, a locking/unlocking mode, and a wash mode, the operating hardware comprising:
- an upper platform track system attached to a window frame of the window complete, the upper platform track system comprising an upper platform base, an upper guide track, and an upper link arm mechanism configured to attach the upper link arm mechanism to a window sash;
- a lower platform track system attached to the window frame, the lower platform unit comprising a lower platform base, a first lower guide track, a second lower guide track wider than the first lower guide track, and a lower link arm mechanism, wherein the lower link arm mechanism is attached to the window sash,
- wherein the lower link arm mechanism comprises a 5-bar scissor linkage including a hinge link, a cross link, an outboard link, a sash link, and a push link, wherein the sash link is mounted to the window sash and attached to the hinge link,
- wherein a first slider shoe floats freely within the second lower guide track and attaches the outboard link to the cross link,
- wherein a second slider floats freely to the lower platform base and attaches the hinge link to the cross link;
- and
- wherein the push link is coupled to the cross link and to the sliding house base;
- a sliding drive system comprising a sliding housing base, a sliding housing top piece, a planetary gear system, and a worm and wheel system,
- wherein the planetary gear system is positioned between the sliding housing top piece and the sliding housing base,
- wherein the worm and wheel gear set comprises a wheel gear mounted to the planetary gear set, and a worm gear positioned between the sliding housing top piece and the sliding housing base and coupled to the wheel gear, and
- wherein the sliding housing top piece is secured to the sliding housing base;
- and
- a handle drive system comprising a hand crank, input bevel gear, a handle drive cap including a first hole for receiving the input bevel gear and a first half hole, an output drive gear, a handle drive base including a second hole for receiving the input bevel gear and a second half hole, and a handle drive shaft,
- wherein the hand crank is mounted in a lower frame section of the window frame,
- wherein the output drive gear is mounted to the handle drive shaft and disposed within the first half hole and the second half hole;
- wherein the handle drive mechanism is mounted to the second lower guide track of the lower platform unit;
- and
- wherein the sliding drive mechanism is configured to secure to and freely slide within the second lower guide track of the lower platform unit.
