Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
A magnetic suspension vehicle for movement relative to a rail arrangement, comprising a vehicle body, a plurality of magnet means elastically mounted on the body for assuming positions spaced from the rail arrangement by given finite distances when energized, said magnet means being serially arranged in a row along the body, said magnet means being individually flexibly mounted on the body, universal coupling means connecting said magnet means to each other along the row to reciprocally adjust the movement of the magnet means relative to the rail arrangement so that when force variations cause one end of one magnet means to deviate from the given finite distances between the magnet means and the rail arrangement by approaching the rail arrangement too closely and conversely by departing too far therefrom, the one end of one magnet tends to draw an adjacent end of the serially adjacent magnet in the same direction and is drawn by the end of the serially adjacent magnet in the other direction.
Claim 2
Dependent Claim
165 words
A magnetic suspension vehicle for movement relative to a rail arrangement, comprising a vehicle body, a plurality of magnet means elastically mounted on the body for assuming positions spaced from the rail arrangement by given finite distances when energized, said magnet means being serially arranged in a row along the body, said magnet means being individually flexibly mounted on the body, universal coupling means connecting said magnet means to each other along the row to reciprocally adjust the movement of the magnet means relative to the rail arrangement so that when force variations cause one end of one magnet means to deviate from the given finite distances between the magnet means and the rail arrangement by approaching the rail arrangement too closely and conversely by departing too far therefrom, the one end of one magnet tends to draw an adjacent end of the serially adjacent magnet in the same direction and is drawn by the end of the serially adjacent magnet in the other direction.
Claim 3
Dependent Claim
43 words
A magnetic suspension vehicle as in claim 1, wherein adjacent ones of said magnet means form couplings which join the adjacent ones of said magnet means to each other, said coupling means permit articulating movement of the magnet means relative to each other.
Claim 4
Dependent Claim
30 words
A magnetic suspension vehicle as in claim 1, wherein spring arrangements mount the magnet means on the body for limiting longitudinal movement of adjacent magnet means relative to each other.
Claim 5
Dependent Claim
29 words
A vehicle as in claim 1, wherein said coupling means permit at least angular relative movement of the magnet means along the longitudinal mid-planes of the respective magnet means.
Claim 6
Dependent Claim
21 words
A vehicle as in claim 4, wherein said coupling means permits articulating movement of the magnet means relative to each other.
Claim 7
Dependent Claim
36 words
A vehicle as in claim 1, wherein each of said magnet means includes a magnet assembly and elastic mounting means connecting the magnet assembly to the body for springily mounting the magnet assembly from the body.
Claim 8
Dependent Claim
40 words
A vehicle as in claim 6, wherein said elastic mounting means includes a rod secured to the magnet assembly and slidably movable perpendicular to the vehicle body and a spring surrounding the rod between the body and the magnet assembly.
Claim 9
Dependent Claim
42 words
A vehicle as in claim 1, wherein each of said magnet means includes a magnet carrier, at least one magnet supported by the carrier, and elastic mounting means connecting the carrier to the body for springily mounting the carrier from the body.
Claim 10
Dependent Claim
37 words
A vehicle as in claim 8, wherein said elastic mounting means includes a rod secured to the carrier and slidably movable perpendicular to the body and a spring surrounding the rod between the body and the carrier.
