Work seat apparatus

Abstract

A work seat apparatus ( 20 ) in which an operator ( 22 ) can work on a workpiece ( 13 ) while seated. The apparatus includes a horizontal first arm part ( 31 ) that is raised and lowered by a raising and lowering part ( 29 ), and a second arm part ( 32 ). The second arm part ( 32 ) is rotatably provided to the first arm part via a joint part ( 34 ). A seat on which the operator sits is rotatably provided to a distal end part of the second arm part and is readily brought near to an operation position.

1 . A work seat apparatus with which an operator can work on a workpiece while seated, the work seat apparatus comprising:
 a base part provided to an anchoring object in a horizontally moveable manner;   a rotating support part provided to the base part so as to be able to rotate about a vertical shaft;   a raising and lowering part that is provided to the rotating support part and that extends and retracts in a vertical direction;   a first arm part that extends horizontally and that is raisably and lowerably supported by the raising and lowering part;   a second arm part that extends horizontally and that is rotatably connected to a distal end of the first arm part via a joint part; and   a seat rotating mechanism that is provided to a distal end of the second arm part and that supports, in a manner that allows rotation about the vertical shaft, the seat part on which the operator sits.   
   
   
       2 . The work seat apparatus of  claim 1 , wherein the base part is designed to be supported by a rail provided to the anchoring object. 
   
   
       3 . The work seat apparatus of  claim 1 , wherein the base part comprises a wheel that travels on the anchoring object. 
   
   
       4 . The work seat apparatus of  claim 1 , wherein a connecting arm connected to a conveying mechanism for conveying the workpiece is provided to the base part. 
   
   
       5 . The work seat apparatus of  claim 1 , wherein the seat part is detachably provided to the seat rotating mechanism. 
   
   
       6 . (canceled) 
   
   
       7 . The work seat apparatus of  claim 1 , wherein the seat rotating mechanism is disposed on either a left side or a right side of the seat part. 
   
   
       8 . The work seat apparatus of  claim 1 , wherein the seat rotating mechanism is disposed to the rear of the seat part. 
   
   
       9 . A work seat apparatus in which an operator can work on a workpiece while seated, the work seat apparatus comprising:
 a support member extending toward the workpiece;   a frame provided to a distal end of the support member;   a rotating member swingably supported by the frame via support shafts; and   a seat part that is attached to the rotating member and is provided with a seat surface part on which the operator sits and a backrest part on which the operator leans back.   
   
   
       10 . The work seat apparatus of  claim 9 , wherein the support member comprises a base part provided to an anchoring object in a horizontally moveable manner; a rotating support part provided to the base part so as to be able to rotate about a vertical shaft; a raising and lowering part that is provided to the rotating support part and that extends and retracts in a vertical direction; a first arm part that extends horizontally and that is raisably and lowerably supported by the raising and lowering part; and a second arm part that extends horizontally and that is rotatably connected to a distal end of the first arm part via a joint part. 
   
   
       11 . The work seat apparatus of  claim 9 , wherein the support shafts are provided above the seat surface part and below an upper end of the backrest. 
   
   
       12 . The work seat apparatus of  claim 9 , wherein in the support shaft, an elastic member that is provided below the seat surface part and that returns the seat part to an original position is disposed between the seat part and the frame. 
   
   
       13 . The work seat apparatus of  claim 9 , wherein the apparatus is provided in a vehicle assembly line, and the support member is disposed to one side of a vehicle.
