Claim 3
Dependent Claim
48 words
A suspension structure as claimed in claim 1, wherein said hangers are respectively provided with damper means at the lower portion thereof, one end of said damper means being connected to said carriage body so as to bias the respective hangers in the direction apart from one another.
Claim 4
Dependent Claim
40 words
A suspension structure as claimed in claim 2, wherein said beam trails an electric power collecting unit which is connected with one end of said beam and travels along an electric power cable provided substantially parallel to said aerial track.
Claim 5
Dependent Claim
198 words
An aerial transport system including an aerial track defining a way along which a carriage travels, the carriage being suspended from said aerial track to rotate in the yaw and pitch directions with respect to the track, wherein a structure for suspending the carriage from the track comprises: a plurality of beams located in spaced apart relationship with respect to one another, each of said beams having vertical axes on both ends thereof and a horizontal axis on the transversely central portion thereof; a pair of wheel supporting frames having one end rotatably supporting a wheel engagable with said track and rotating therealong, and the other end rotatably connected with both ends of each beam, said frame being rotatable in the yaw direction about said vertical axis of said beam; and a hanger having one end connected with said beam and being rotatable about said horizontal axis of said beam and the other end provided with joining means which has both vertical and horizontal axes and through which said other end is connected with said carriage so that said carriage is universally rotatable in yaw and pitch directions about said vertical and horizontal axes of said joining means.
Claim 6
Dependent Claim
198 words
An aerial transport system including an aerial track defining a way along which a carriage travels, the carriage being suspended from said aerial track to rotate in the yaw and pitch directions with respect to the track, wherein a structure for suspending the carriage from the track comprises: a plurality of beams located in spaced apart relationship with respect to one another, each of said beams having vertical axes on both ends thereof and a horizontal axis on the transversely central portion thereof; a pair of wheel supporting frames having one end rotatably supporting a wheel engagable with said track and rotating therealong, and the other end rotatably connected with both ends of each beam, said frame being rotatable in the yaw direction about said vertical axis of said beam; and a hanger having one end connected with said beam and being rotatable about said horizontal axis of said beam and the other end provided with joining means which has both vertical and horizontal axes and through which said other end is connected with said carriage so that said carriage is universally rotatable in yaw and pitch directions about said vertical and horizontal axes of said joining means.
Claim 7
Dependent Claim
32 words
A suspension structure as claimed in claim 4 further comprising a link member for connecting the opposed ends of adjacent separated beams and wherein said link member is made of flexible material.
Claim 8
Dependent Claim
48 words
A suspension structure as claimed in claim 4, wherein said hangers are respectively provided with damper means at the lower portion thereof, one end of said damper means being connected to said carriage body so as to bias the respective hangers in the direction apart from one another.
Claim 9
Dependent Claim
39 words
A suspension as claimed in claim 6, wherein said beam trails an electric power collecting unit which is connected with one end of said beam and travels along an electric power cable provided substantially parallel to said aerial track.
Claim 10
Dependent Claim
