Definitions

  • the present invention relates to a window blind apparatus which is disposed in a window of a building to hinder sight and shut out light for the interior of a room.
  • Patent Document 1 JP-A-2004-156289
  • Window blind apparatuses are known in which a plurality of slats are arranged vertically in a window of a building to hinder sight and shut out light for the interior of a room by the raising/lowering and tilting of the slats.
  • a raising and lowering device for raising and lowering the slats and a tilting mechanism for tilting the slats are provided in such a window blind apparatus.
  • the plurality of slats superposed on each other and bundled are generally disposed on the ceiling side.
  • the plurality of slats which, in the full opening of the window, are superposed on each other and bundled so as not to obstruct the field of view through the window and, where necessary, to allow sufficient daylight to be obtained, are preferably disposed on the ceiling side without greatly covering an upper portion of the window.
  • the upper portion of the window is greatly covered by these bundled slats unless the ceiling is made high.
  • the slats are linked to each other by link mechanisms having cord-like bodies; however, if the slats are bundled in the full opening of the window, such cord-like bodies droop to the outside from between the slats, which mars the beauty of the room interior. Furthermore, if such a droop to the outside occurs partially, an irregularity occurs in the height of the slats between the left and the right, which also mars the beauty.
  • the window blind apparatus which is installed at the window, has a possibility of being fouled early due to dust and the like, so that it is desirable to perform frequent cleaning.
  • the window blind apparatus since the slats are normally linked to each other by the cord-like bodies of the link mechanisms, the window blind apparatus is inferior in assembling and disassembling efficiency, with the result that cleaning is time-consuming and may possibly involve large-scale work.
  • the slats are normally linked to each other by the cord-like bodies of the link mechanisms, and are hung down at the window at the time of shutting out the light or hindering sight.
  • the slats being swung by the external wind or the wind from an indoor air-flow system. Such swinging of the slats shortens the life of the link mechanisms, and can lead to the damage of surrounding objects in some cases.
  • the present invention has been devised in view of the above-described aspects, and its object is to provide a window blind apparatus in which the plurality of bundled slats can be disposed on the ceiling side as practically as possible, thereby making it possible to obtain sufficient daylight without obstructing the field of view through the window.

  • Still another object of the present invention is to provide a window blind apparatus which excels in assembling and disassembling efficiency, thereby making it possible to reduce the manufacturing cost and facilitating cleaning.
  • a further object of the present invention is to provide a window blind apparatus in which the plurality of slats hanging down at the window can be held so as not to sway due to the wind or the like, thereby preventing the occurrence of an unexpected accident or the like and making it possible to improve the product life.

  • the transmitting mechanism may include an idling mechanism for idling the rotating shaft of the rotational power source with respect to the rotator in a case where the rotational load of the rotator increases due to the abutment of the coupling pin member against the fixed plate at an end of the guide hole.
