Abstract: A multi-function roller skate system functions as a conventional skate configuration, with the wheels wide apart, and also as an in-line skate configuration, with a single row of wheels. The skate has multiple pairs of wheels which may be moved closer together or farther apart according to the skater's needs, either in connection with training or to accommodate changing skating conditions. When the wheels are at their closest, each pair operates as a single wheel directly under the skater's foot like an in-line skate. The skate may include at least one intermediate position for intermediate skill skaters. In addition, the skate may be extended to fit different or growing skaters.

Abstract: Disclosed is an adjustable lamp assembly especially suitable for use as a table or desk lamp. The lamp assembly has a substantially spherical or conical base member having an adjustable center of gravity which allows it to be moved and retained in a variety of inclined and tilted positions. Also disclosed is a lamp assembly having a concave shade member having a peripheral rim and a central opening adapted to rest upon and be supported freely on the curved outer surface of a lamp bulb globe whereby the peripheral rim of the shade member will remain in a horizontal plane as the lamp assembly is tilted relative to the horizontal plane.
