Definitions

  • the present invention relates to a door/window comprising an operating system with multiple locking points, especially to an operating system for inward tilt-turn doors/windows with multiple locking points.
  • the operating mechanism for a multi-point lock has following shortcomings. Firstly, two casing parts 5a, 5b of a gear casing 5 are made by zinc alloy die-casting. Thus the cost of materials required is high and the total weight is heavier. This has negative effects on the competitiveness of the company. Moreover, riveting is used to join the two casing parts 5a, 5b. The riveting requires a larger force applied to rivets to have impact on the gear casing 5. Such structure and the technique consume more energy during application.
  • a gear housing for windows or doors which comprises threaded sleeves arranged in an insertion position in a ventral position of moving areas, wherein the gear housing is released to both directions of the moving areas of the threaded sleeves in order to allow the movement by a screw connection with a handle on the insertion position in the corresponding releasing position, and wherein the threaded sleeves are flexibly connected with the housing units.
  • US 6,076,304 A discloses a window opening and closing assembly.
  • the assembly is formed of molded plastic which includes first and second housing members suitably secured together with a rack slidably mounted in the housing.

  • the second side of the inner frame can be added with a lock point so as to prevent the second side from being opened by intruders and provide a good anti-theft function when an embedded hinged corner device is installed on top of the second side of the inner frame and the embedded hinged corner device is also connected to a drive bar.
  • An outer edge of the frame strip of the inner frame is disposed with two adjacent projections and a stopper is extended inward from a side end of each projection.
  • a sliding groove is formed on the frame strip and is defined by the projections and the stoppers.
  • the gear casing includes a plastic first casing and a plastic second casing, corresponding to each other.
  • a gear controlled by the handle is mounted inside the first and the second casings.
  • the gear drives a rack set on a moveable frame to slide and move so as to open or close the door/window by sliding of the moveable frame connected with the first and the second casings.
  • the first casing is disposed with at least one insertion hole while the second casing is arranged with at least one projecting bored connecting rod on an inner surface thereof.
  • the number of the projecting bored connecting rod is the same with the number of the insertion hole.
  • a plurality of grooves is arranged annularly around the bored connecting rod.
  • the arrangement of the grooves allows tightening pieces to be expanded outwards and elastically deformed while being applied with forces.
  • An entrance angle is formed on an inner edge of a side end of the tightening piece.
  • the embedded hinged corner device includes a main body, a first block, a second block, a flexible piece, and a C-shaped lock.
  • the main body consists of a horizontal extension segment and a vertical extension segment, respectively disposed with a guiding rail for receiving the first block and the second block.
  • the first block and the second block sliding inside the guiding rail are connected by the flexible piece. While in use, the first block is pushed or pulled and the second block is sliding or stopped from sliding along with the first block synchronously due to the flexible piece that transmits a driving force.
  • the lock point on the second side of the door/window is shifted between a lock state and an unlocked state through the sliding movement mentioned above.
  • Each of two sides of the horizontal extension segment is disposed with a projecting sliding block.
  • the embedded hinged corner device By the sliding blocks being slid along with the horizontal extension segment and into the sliding groove of the frame strip on top of the inner frame, the embedded hinged corner device is fixed on a corner on top of the second side of the inner frame and an inner surface of the vertical extension segment is attached to the stopper of the frame strip on a lateral side of the inner frame. Moreover, the embedded hinged corner device is fastened from the top side by the C-shaped lock. Thus the embedded hinged corner device is positioned on the inner frame by dual mechanisms. Thereby the assembly of the operating system for doors/windows with multiple locking points is completed.
  • a door/window 10 includes an outer frame 11 and an inner frame 12.
  • the inner frame 12 is formed by four frame strips 13 and a petition plate (such as a piece of glass or wood) is mounted therein.

  • a gear 23 controlled by the handle 30 is mounted inside the first casing 21 and the second casing 22.
  • the gear 23 rotates and causes a rack 241 arranged at a moveable frame 24 to slide and move.
  • the door/window 10 is opened or closed according to changes of sliding positions of the moveable frame 24 connected with the first and the second casings 21, 22.
  • the first casing 21 is disposed with at least one insertion hole 211 while the second casing 22 is arranged with at least one projecting bored connecting rod 221 on an inner surface thereof.
  • the number of the projecting bored connecting rod 221 is the same with the number of the insertion hole 211 and the number is two in this embodiment.
  • a plurality of grooves 222 is disposed annularly around the bored connecting rod 221. The formation of the grooves 222 allows tightening pieces 223 to be expanded outwards and elastically deformed when forces are applied to the tightening pieces 223.
  • An entrance angle 224 is formed on an inner edge of a side end of the tightening piece 223.
  • a positioning pin 25 is passed through the insertion hole 211 and inserted into the bored connecting rod 221.
  • the positioning pin 25 presses the tightening piece 223 to expand outward so as to make the bored connecting rod 221 fit in the insertion hole 211 of the first casing 21 firmly.
