Abstract
Provided is a chair for a ship with horizontality maintaining structure for preventing passengers on board the ship from getting motion sickness by maintaining the horizontality of the chair installed in cabins and the like in response to wobbles of the ship. The chair for a ship with horizontality maintaining structure according to the present disclosure includes an external frame 10 which is installed in a fixing way on the hull floor; an internal frame 20 which is integrated inside the external frame 10 so that it rotates back and forth; a seat unit 30 which is integrated inside the internal frame 20 so that it rotates from side to side; and a horizontality maintaining means 40 which is formed in the lower part of the seat unit 30.
Claims7
A chair for a ship with horizontality maintaining structure, including:
- an external frame which is installed in a fixing way on a hull floor;
- an internal frame which is integrated inside the external frame so that it rotates back and forth;
- a seat unit which is integrated inside the internal frame so that it rotates from side to side;
- and
- a horizontality maintaining means which is formed in the lower part of the seat unit,
- wherein the external frame comprises:
- a left member which is installed in a fixing way on the hull floor and has the shape of a quadrangle plate;
- and
- a right member which has the same shape as that of the left member and is installed in a fixing way on the hull floor at a distance from the left member to be parallel with the left member;
- the internal frame comprises:
- a back which has the shape of a quadrangle plate, a left plate which has the shape of a quadrangle plate and is installed in a fixing way on the left side of the back so that the left plate protrudes therefrom;
- and
- a right plate which has the same shape as that of the left plate and is installed in a fixing way on the right side of the back so that the right plate protrudes therefrom;
- the internal frame is integrated between the left member and the right member of the external frame;
- a fastening hole is formed at a predetermined corresponding location of the left member of the external frame and the left plate of the internal frame and the right member of the external frame and the right plate of the internal frame, respectively;
- a fastening member is inserted through the fastening hole for the internal frame to be integrated inside the external frame so that the internal frame rotates back and forth;
- a second fastening hole is formed at a predetermined location at the center of the back of the internal frame while a second fastening member is inserted in the second fastening hole so that the seat unit is integrated on the front side of the back;
- the seat unit comprises a seat and a rim;
- the second fastening member penetrates from a rear surface of the rim through the inside of the seat to a front surface of the rim, thereby being inserted in the seat in a forward-backward direction to act as the axis of rotation of the seat unit in a left-right direction for the seat unit to be integrated inside the internal frame so that the seat unit rotates from side to side;
- the horizontality maintaining means is formed in a lower part of the seat unit so as to keep the center of gravity of the horizontality maintaining means in a vertically downward direction;
- and
- the internal frame is integrated with the external frame, which is fixed on the hull floor, so that the internal frame rotates back and forth and the seat unit inclines backward and forward according to the forward-backward rotation of the internal frame to respond to pitching of the hull while the seat unit is integrated with the internal frame so that the seat unit rotates from side to side to respond to rolling of the hull by the action of the horizontality maintaining means.
