Abstract
Abstract The device includes a platform mounted on a base and adapted to support a person's hands or feet in side-by-side relation. A slotted plate defines left and right sets of air-directing channels between the platform and the base. A rotatable impeller circulates air through a manifold and into the channels with the air being discharged upwardly from the channels and through ports in the platform to relax and refresh the hands or feet. A weight attached to one of the blades of the impeller causes the platform to vibrate and further induce relaxation.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
209 words
A device for relaxing and refreshing left and right terminal limbs having digits, said device comprising an upper, generally horizontal platform of sufficient length and width to enable left and right limbs to rest on the platform in side-by-side relation, a lower base underlying and supporting said platform, means defining left and right sets of channels between said platform and said base, each of said sets comprising at least two distinct channels positioned to underlie different areas of the respective limb, a manifold between said platform and said base and communicating with all of said channels, said means comprising a plate sandwiched between said platform and said base, slots formed through said plate and defining said channels, an opening formed in said plate and defining said manifold, the upper and lower sides of said slots and said opening being closed by said platform and said base, respectively, a hole formed in said platform above said manifold, a rotatable impeller alined with said hole and operable when rotated to circulate air in said manifold and into said channels, a motor for rotating said impeller, and ports formed through said platform and overlying said channels whereby upwardly directed air streams are emitted from said ports to relax and refresh said limbs.
Claim 2
Independent Claim
209 words
A device for relaxing and refreshing left and right terminal limbs having digits, said device comprising an upper, generally horizontal platform of sufficient length and width to enable left and right limbs to rest on the platform in side-by-side relation, a lower base underlying and supporting said platform, means defining left and right sets of channels between said platform and said base, each of said sets comprising at least two distinct channels positioned to underlie different areas of the respective limb, a manifold between said platform and said base and communicating with all of said channels, said means comprising a plate sandwiched between said platform and said base, slots formed through said plate and defining said channels, an opening formed in said plate and defining said manifold, the upper and lower sides of said slots and said opening being closed by said platform and said base, respectively, a hole formed in said platform above said manifold, a rotatable impeller alined with said hole and operable when rotated to circulate air in said manifold and into said channels, a motor for rotating said impeller, and ports formed through said platform and overlying said channels whereby upwardly directed air streams are emitted from said ports to relax and refresh said limbs.
Claim 3
Dependent Claim
31 words
A device as defined in claim 1 in which said impeller is located within said hole, the lower end of said impeller being located below the lower side of said platform.
Claim 4
Dependent Claim
26 words
A device as defined in claim 1 in which the channels of said left set are a mirror image of the channels of said right set.
Claim 5
Dependent Claim
34 words
A device as defined in claim 1 in which the channels of said left set and the channels of said right set are located symmetrically with respect to the longitudinal centerline of said platform.
Claim 6
Dependent Claim
54 words
A device as defined in claim 1 for relaxing and refreshing left and right feet, each set of channels having a generally laterally extending channel positioned to underlie the toes of the respective foot and having a generally longitudinally extending channel positioned to underlie the inner side of the arch of the respective foot.
Claim 7
Dependent Claim
50 words
A device as defined in claim 1 for relaxing and refreshing left and right hands, each set of channels having a generally laterally extending channel positioned to underlie the fingers of the respective hand and having another generally laterally extending channel positioned to underlie the palm of the respective hand.
Claim 8
Dependent Claim
31 words
A device as defined in claim 6 in which each set of channels further includes a third channel positioned to underlie both the thumb and the palm of the respective hand.
Claim 9
Dependent Claim
20 words
A device as defined in claim 1 further including means for causing said impeller to impart vibration to said platform.
Claim 10
Dependent Claim
43 words
A device as defined in claim 8 in which said impeller comprises a plurality of angularly spaced blades, said last-mentioned means comprising a weight attached to one of said blades to cause said impeller to be angularly unbalanced and to vibrate said platform.
Claim 11
Dependent Claim
48 words
A device as defined in claim 1 further including a housing on the upper side of said platform, said motor being enclosed in said housing, and openings in said housing to enable said impeller to draw air into said housing for circulation through said manifold and said channels.
Claim 12
Independent Claim
196 words
A device for relaxing and refreshing left and right feet, said device comprising an upper, generally horizontal platform of sufficient length and width to enable left and right feet to rest on the platform in side-by-side relation, a lower base underlying and supporting said platform, a plate sandwiched between said platform and said base, left and right sets of slots formed through said plate and having upper and lower sides closed by said platform and said base, respectively, each set of slots comprising a generally laterally extending slot positioned to underlie the toes of the respective foot and further comprising a generally longitudinally extending slot positioned to underlie the inner side of the arch of the respective foot, an opening formed through said plate and defining a manifold communicating with all of said slots, a hole formed in said platform above said opening, a rotatable impeller alined with said hole and operable when rotated to circulate air in said opening and into said slots, a motor for rotating said impeller, and ports formed through said platform and overlying said slots whereby upwardly directed air streams are emitted from said ports to relax and refresh said feet.
Claim 13
Independent Claim
