Traveling rails for carriage

Abstract

In a carriage traveling rail to which a carriage is movably attached, upper ends of a plurality of suspenders are fixed to a ceiling and the suspenders extend downward. A first linear rail member is elongated in one direction and suspended by the suspenders which are arranged with a prescribed interval. A curved rail module is curved in a vertical plane and elongated in the curved direction. The curved rail module is suspended by the suspenders which are arranged with a prescribed interval and includes a curved member having a curved face which is curved in the vertical plane along the elongated direction, and a plurality of second linear rail members elongated in one direction and fixed to the curved member. The second rail members are shorter than the first linear rail member in length relative to the elongated direction. The second linear rail members are in contact with the curved face while being so arranged that adjacent ones of the second linear members are elongated in directions different from each other and end faces in the elongated direction of the adjacent ones of the second linear members oppose each other, so that the carriage travels while being guided by the second linear rail members.

1 . A carriage traveling rail, to which a carriage is movably attached, comprising: 
 a plurality of suspenders, each of which is extended downward from a ceiling;    a first linear rail member, having a first longitudinal dimension and suspended by the suspenders; and    a curved rail module, comprising:    a curved member, suspended by the suspenders and having a curved face which is curved in a vertical plane along an elongated direction thereof; and    a plurality of second linear rail members, each of which is fixed to the curved member and has a second longitudinal dimension shorter than the first longitudinal dimension, wherein:    the second linear rail members are arranged along the curved face such that adjacent ones of the second linear members are elongated in directions different from each other and longitudinal end faces of the adjacent ones of the second linear members oppose each other.    
   
   
       2 . The carriage traveling rail as set forth in  claim 1 , wherein the curved member is either a convex curved member in which the curved face is convex toward the second linear rail members or a concave curved member in which the curved face is convex concaved from the second linear rail members.
