Claim 6

A foldable caster according to claim 4, wherein said base plate and said caster support plate are substantially flat.

Claim 7

A foldable caster according to claim 3, wherein said base plate is magnetic and said swivel has magnetically attractive metal portions which contact said magnetic base plate to magnetically secure said caster in said storage position.

Claim 8

A foldable caster according to claim 6, wherein said magnetically attractive portions comprise a pair of flanges which together support said caster wheel bearing.

Claim 9

Claim 10

A foldable caster and caster housing comprising: a) a caster housing; b) a caster base plate slidably received in a pair of opposed grooves in said housing; c) a caster support plate, said support plate being hingedly connected along a first axis to said base plate for movement of at least 180° around said first axis, said first axis being perpendicular to the direction of movement of said base plate into said housing grooves; d) a caster swivel affixed to said caster support plate for rotary movement relative thereto about a second axis perpendicular to said first axis, said swivel having means for rotatably supporting a caster wheel thereon; e) a caster wheel rotatably mounted on said swivel for rotation about a third axis which is substantially perpendicular to said second axis; f) means for securing said caster support plate to said base plate on a first side of said base plate with said caster wheel operatively positioned outside of said housing; and g) means for securing said swivel and caster wheel for storage in said housing with said swivel on the side of said base plate opposite said first side of said base plate.

Claim 11

A foldable caster and caster housing according to claim 8, wherein said support plate is moveable approximately 270° around said first axis.

Claim 12

A foldable caster and caster housing according to claim 9, wherein said means for securing said caster support plate in at least one of said positions are magnetic.

Claim 13

A foldable caster and caster housing according to claim 8, wherein said base plate is magnetic and said caster support plate is magnetically attractive metal.

Claim 14

A foldable caster and caster housing according to claim 11, wherein said base plate and said caster support plate are substantially flat.

Claim 15

A foldable caster and caster housing according to claim 10, wherein said base plate is magnetic and said swivel has magnetically attractive metal portions which contact said magnetic base plate to magnetically secure said caster in said storage position.

Claim 16

A foldable caster and caster housing according to claim 13, wherein said magnetically attractive portions comprise a pair of flanges which together support said caster wheel.

Claim 17

A foldable caster and caster housing according to claim 8, wherein said caster is secured for storage in said housing by friction contact between said caster swivel and wall portions of said housing.
