Abstract
An amusement device having a rotating carriage and means for rotating the carriage. A plurality of spaced apart sliding members is connected to the rotating carriage. A plurality of magnetic actuators, act upon the sliding members as the sliding members rotate relative to the magnetic actuators. An electromagnetic force applied by the magnetic actuators to the sliding members causes the device to lift.
Claims
exact text as granted — not AI-modified1 . An amusement device, comprising:
(a) a frame having vertical supports, a support platform and a frame bottom member; (b) a rotating carriage that is located within said frame having a carriage base plate and a carriage top and includes a rotator about which the rotating carriage is mounted, said rotator extending upward through said support platform; (c) a plurality of evenly spaced apart sliding members, wherein said sliding members are slidably connected on rods between carriage base plate and a carriage top said, rods being disposed at an angle from the vertical of between 15° and 35°; (d) a plurality of magnetic actuators that are evenly spaced apart and mounted under said support platform and act upon said sliding members as said sliding members rotate relative to said magnetic actuators; and (e) means for rotating said carriage connected to said rotator so as to cause said device to lift from the surface on which it is placed.
2 . The lifting device as described in claim 1 , wherein each of said sliding members travel along a line that is 22° from said vertical axis.
3 . The lifting device as described in claim 1 , wherein said plurality of magnetic actuators do not rotate at the same rate of rotation as said sliding members.
4 . The lifting device as described in claim 1 , said lifting device comprising at least four sliding members.
5 . The lifting device as described in claim 1 , said lifting device comprising at least four magnetic actuators.
6 . A lifting device, comprising:
(a) a frame having vertical supports, a support platform and a frame bottom member; (b) a rotating carriage that is located within said frame having a carriage base plate and a carriage top and includes a rotator about which the rotating carriage is mounted, said rotator extending upward through said support platform; (c) a plurality of evenly spaced apart sliding members, wherein said sliding members are slidably connected on rods between carriage base plate and a carriage top said, rods being disposed at an angle from the vertical of between 15° and 35°; (d) a plurality of magnetic actuators that are evenly spaced apart and mounted under said support platform and act upon said sliding members as said sliding members rotate relative to said magnetic actuators; and (e) means for rotating said carriage connected to said rotator, wherein each of said plurality of magnetic actuators force said sliding members downwardly at predetermined intervals.
7 . The lifting device as described in claim 6 , wherein each of said sliding members travel along a line that is 22° from said vertical axis.
8 . The lifting device as described in claim 6 , wherein said pluralities of magnetic actuators do not rotate at the same rate of rotation as said sliding members.
9 . The lifting device as described in claim 6 , said lifting device comprising at least four sliding members.
10 . The lifting device as described in claim 6 , said lifting device comprising at least four magnetic actuators.
11 . The lifting device as described in claim 6 , wherein said actuators are located upon said rotating carriage.
12 . The lifting device as described in claim 11 , wherein one of said actuators is positioned above each of said sliding members.Join the waitlist — get patent alerts
