Document Type and Number:
Japanese Patent JP2005515862
Kind Code:
A
Abstract:
A skate (10) includes a base plate (11) pivotally carrying a platform plate (14) which can be the sole of a shoe (16). There is an aperture (18) in the base plate (11) so that when the platform plate (14) is adjacent to the base plate (11), a pad (17) on the platform plate (14) extends through the aperture (18) so that the user may walk on the skate (10). A frame (23) carries a drive shaft (20) which carries drive wheels (19). The drive shaft (20) is journalled in unidirectional bearings (21) and has a gear (32) which engages a threaded motor shaft (31) of a motor (27). A collar (38) has threads (37) which engage the threads (36) of a motor housing (33). When the motor (27) rotates in the one direction permitted by the unidirectional bearings (21), the drive wheels (19) will power the skate (10). When, upon voice command, the motor (27) attempts to rotate the shaft (31) in the other direction, the motor (27) rotates so that the collar (38) moves relative to the housing (33) to move the pad (17) through the aperture (18).
