Abstract
Abstract A device for stimulating the soles of a person's feet comprises a plastic holder having a central recess. A multiplicity of spherical plastic bearings of different sizes are supported within the recess in a loosely-packed layer. A dampening medium such as a gel surrounds the bearings to dampen their movement. A plastic film overlays the bearings and conforms to the shape of the underlying bearings when stepped on by the feet. A user simply stands on the plastic film and rocks thereby displacing the bearings and stimulating various parts of the bottoms of his feet.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
84 words
A device for stimulating a person's feet, comprising: a holder having a recess; a multiplicity of rigid spheroid members supported in a loosely-packed layer within the recess; a dampening medium located within the recess and engaged with the spheroid members to dampen movement of the spheroid members; and, a cover attached to the holder and overlaying the layer of spheroid members, the cover being formed of a material which conforms to the shape of the underlying spheroid members when stepped on by the feet.
Claim 2
Independent Claim
84 words
A device for stimulating a person's feet, comprising: a holder having a recess; a multiplicity of rigid spheroid members supported in a loosely-packed layer within the recess; a dampening medium located within the recess and engaged with the spheroid members to dampen movement of the spheroid members; and, a cover attached to the holder and overlaying the layer of spheroid members, the cover being formed of a material which conforms to the shape of the underlying spheroid members when stepped on by the feet.
Claim 3
Dependent Claim
19 words
A device as claimed in claim 1 in which the dampening medium is a gel surrounding the spheroid members.
Claim 4
Dependent Claim
18 words
A device as claimed in claim 1 in which the spheroid members have a plurality of different sizes.
Claim 5
Dependent Claim
15 words
A device as claimed in claim 1 in which the cover is a plastic film.
Claim 6
Independent Claim
103 words
A device for stimulating a person's feet, comprising: a holder having a recess; a multiplicity of rigid spheroid members retained within the recess, the spheroid members being characterized by a plurality of predetermined different sizes; a cover attached to the holder and overlaying the spheroid members, the cover being formed of a material which conforms to the shape of the underlying spheroid members when stepped on by the feet; the spheroid members being loosely packed such that the spheroid members can be displaced in response to a user stepping on the cover to expose the user's feet simultaneously to spheroids of different sizes.
Claim 7
Independent Claim
103 words
A device for stimulating a person's feet, comprising: a holder having a recess; a multiplicity of rigid spheroid members retained within the recess, the spheroid members being characterized by a plurality of predetermined different sizes; a cover attached to the holder and overlaying the spheroid members, the cover being formed of a material which conforms to the shape of the underlying spheroid members when stepped on by the feet; the spheroid members being loosely packed such that the spheroid members can be displaced in response to a user stepping on the cover to expose the user's feet simultaneously to spheroids of different sizes.
