Definitions

  • the present invention relates to a pressing type latch device and, more particularly, to a pressing type latch device that can be set to include a plurality of retainable open positions and a retainable closed position.
  • U.S. Patent No. 7,452,010 discloses a handle for moving a pull shaft between an upper position and a lower position in the vertical direction. When the pull shaft is in the lower position, a latch bar can engage the hatch jamb in a latched position.
  • the shape of the handle matches with a well of a housing to precisely move the latch bar to the latched position, such that the handle can be inserted into the well only after 180° rotation to achieve a closing state or an open state.
  • a pin of the pull shaft must be located in a slot of a boss of the housing, such that the handle can only actuate the latch bar in a fixed direction for closing or opening purposes.
  • Closing and opening of the above D-handle latch must be operated in a specific direction, and the handle can be inserted into the well only after 180° rotation. Thus, the installer must notice the operating direction during installation, which is inconvenient. Furthermore, if a user applies the force in the wrong direction, the boat latch cannot be opened, and the latch could even be damaged.
  • the primary objective of the present invention is to provide a latch device including a handle pivotably connected to two eccentric locations of a body of a pivotal seat, such that a greater operational height can be formed when the handle is lifted. Furthermore, the latch device can be set to include a plurality of retainable open positions and a retainable closed position. Thus, the latch device can be installed and used more easily.
  • the secondary objective of the present invention is to use an engaging member of a pivotal seat of the latch device to secure the handle in a state preventing burglars or preventing mistaken opening, such that the handle cannot be lifted and rotated.
  • a pressing type latch device including a seat, a pivotal seat, and a handle.
