The concept of ergonomics, that is the tudy of how the human
body interacts with a mechanical environment, is being applied to
the design of office furniture, computer terminals and equipment
generally operated by human being~ in a sitting postion. The
application of ergonomic principles to designs of such devices
has as its intended purpose the reduction o fatigue, stre~s and
discomfort in daily work situations.
Several text~ are available which de~cribe and teach the use
of ergonomics in order to increase productivity of humans. One
such text i8 in a book entitled THE BIOMEDICAL BASIS OF
ERGONOMICS (1978), E. R. Tichauer, published by
Wiley-Interscience Publication which setsforth at page 71 thereof
the advantages of properly designed chairs in a production
environment.
Also, numerous medical reports and article~ are well known in
the art which teach the advantages of elevating the feet of a
user in a sitting position to relieve fatigue in the legs and
thighs.
However, the art is devoid of any suggestions, teachings or
di~closures which recognize the advantages associated with an
apparatus having both a foot massaging ~urface and a foot
receiving and support surface and having the same positioned at
a slope which approximates the ergonomic design angle which is
adapted to reduce atigue, stress and discomfort of the thigh,
lower leg and foot of a human user in a sitting position.
SUMMARY OF THE INVENTION
The present invention relates to a new, novel and unique com-
bined foot mas~age and support. In the preferred embodiment, the
combined foot massage and support includes a base ~upport which
has a base plate having a substantially planar surface and a
071983-837.1
~ ~LS926
~econd opposite surface and a circular ~haped opening located
centrally therein. The combined foot massage and support inclu-
des a pair of substantially planar side support members each of
which terminate in a first support end and a second support end.
The first support end of each of the side ~upport members include
means deining a substantially planar support surface and the
second support end of each of the side support members are
located opposite the first support end and includes mean~
defining a ramp support surface having a a slope which approxima-
tes the ergonomic design angle which is adapted to reduce fati-
gue, strefis and discomfort of the thigh, lower leg and ~oot of a
human user in a sitting position. The substantially planar side
support members are operatively coupled to and extending in the
same substantially normal direction from the ba~e support and
base plate and in a spaced parallel relation~ip to each other
with the substantially planar support surface of the first sup-
port end of each of said side support members positioned adjacent
the base support and with the ramp support sur~ace of the ~econd
support end of each of said side support members positioned with
the ramp support surface extending in the same direction. The
suppport Eurther includes a plurality of massage as3emblies each
of which include an axially extending center support member and a
plurality of annular shaped mas~age elements mounted axially on
and rotatable about said center support members. The center sup-
port members are mounted in an arcuate, ~paced parallel alignment
between the spaced parallel planar side ~upport members above the
base support and above the opposite slde of the base plate. The
plurality of massage elements are mounted on the center ~upport
members and have a radius which extends therefrom to below the
ramp support surfaces to form a convex shaped, angularly disposed
' 071983-837.1
~2~9Z~
treating surface which extends sub3tantially between the substan-
tially parallel side support members. The support member has a
means including a rotatable disc positioned in the circular
opening in the ba~e plate which is adapted to be engaged and
rotated by at least one foot of a user. The foot massage and
support are adapted to have a mas~age position wherein the base
support, the 6ubstantially planar surface of the base plate and
the substantially planar surface of the side support members are
positioned on a supporting surface placing the convex shaped,
angularly disposed treating ~urface in a ma~sage position which
is adapted to receive the feet of a user. The feet of a u6er may
be ma6saged by movement of the feet relative to the rotatably
mounted mas6age elements and a support position wherein the ramp
support surfaces of the second support end of each side 6upport
members are po~itioned on a supporting surface placing the base
support including the substantially planar surface of the base
plate at an angle to receive and support the feet of a user.
The present invention overcome6 certain of the deficiencies
of the known prior art footrests. None of the known prior art
devices ~uggest or disclose the po6itioning of foot massaging
devices at an angle which approximates the ergonomic design angle
which iB adapted to reduce fatigue, stres6 and discomfort of the
thigh, lower leg and foot of a human user in a sitting position.
One advantage of the present invention i~ that a combined
foot ma6sage and support device i3 di~closed wherein both the
foot treating surface and the foot receiving and supporting sur-
face are at the ergonomic design angle.
Another advantage of the present invention is that the foot
treating surface can be formed of a plurality of massage
a~semblies each of which include an axially extending center sup-
port member and a plurality of annular ~haped mas~age elements

mounted axially on and rotatably about said center support
members which are mounted in an arcuate, spaced parallel align-
ment between spaced parallel planar ~ide support members to form
an arch ~ype surface which is adapted to conform with the arch of
the foot of a user.
A yet another advantage of the present invention is that the
foot receiving and supporting surface and the foot treating sur-
face can be easily xeversed by merely reversing the integral foot
massage and foot support apparatus.
A still yet further advantage of the present invention iB the
the foot receiving and supporting surface can be fixed relative
to the foot treating ~urface at the desired ergonomic design
angle.
A yet still further advantage of the present invention is
that the foot receiving and support surface can be covered with a
rubberized matt or resilient covering, having a plurality of
~ubstantially parallel protruding members which can be used to
cushion or resiliently support the feet~ Also, the resilient
covering ~timulates circulation in the foot as a result of
relative movement therebetween.
A still yet further advantage of the present invention is
that the base support can be integral with the apparatus housing
and a base plate can be pivotally mounted to the base support
such that the angle of the base plate can be varied relative to
the baae support by an elongated rod and cam a~embly.
Another advantage of the preaent invention i8 that the
selected ergonomic de~ign angle further helps circulation of the
body in the unstre6sed area and further reduces pressure,
compre~sion and strain on the back.
~L%~5~ZE;
0719~3-837.1
Another advantage of the present invention is that a combined
foot massage and support device can be fabricated in a width to
accomodate one foot of a user.
Another advantage of the present invention is that the base
plate can be Pabricated with a rotatable disc located centrally
therein to enable a user to place a foot thereon and obtain exer-
cise by rotating the disc with the foot.
A still yet further advantage of the pre~ent invention i~
that the base plate can be centrally pivotly mounted on the side
walls such that a user can exercise a foot by a pitching axis
about the pivotal axis of the base plate.
A stii yet further advantage of the preaent invention is that
the pivotaly base plate can be split to as to permit independent
pitching movement of each half of the base plate with the feet of
a user.
A still further advantage of the present invention is that
the base plate, with or without the rotatable disc, can be sli-
deably mounted to the side supports to enable a user to slideably
extend the base plate along a plane and to still pivot or pitch
the base plate about the pivotal axis.

port which is shown generally by arrow 20. The combined foot
massage and support comprises a base support 22 which includes a
base plate 24. The base plate 24 i~ integral with the ba~e sup-
port 22 which forms part of a houslng means shown generally as
26. The base plate 24 has a substantially planar ~urface 30 and
a second opposite surface 32. The housing means includes means
for deflning a pair of sùbstantially planar side support members
38 and 40, each of which term,inate in a first ~upport end 44 and
46, respectively, and a second ~upport end 48 and 50, respec-
tively. The first ~upport ends 44 and 46 of side support members
38 and 40, respectively, including means defining a sub6tantially
planar ~upport qurface 60 and 62, respectively. The second sup-
--10--
~5~32~
071983-837.1
port ends 48 and 50 of side support members 38 and 40, respec-
tively, are located opposite the first support ends 44 and 46,
respectively. The second support ends 48 and 50 include means
defining a ramp support surface 66 and 68 respectively. The ramp
support surfaces 66 and 68 extend a selected distance and have a
slope which approximates the ergonomic design angle which is
adapted to reduce ~atigue, ~tress and discomfort of the thigh,
lower leg and foot of a human user in a sitting po~ition. The
substantially planar side support members 38 and 40 are opera-
tively coupled to and extend in the same substantially normal
direction from the base support 22 and base plate 24 and in a
spaced parallel relationship to each other with the sub~tantially
planar suppc)rt surfaces 60 and 62 of the first support ends 44
and 46, respectively, of the side ~upport members 38 and 40 posi
tioned adjacent the base support 22 and with the ramp ~upport
surfaces 66 and 68 positioned to extend in the same direction.
A plurality of massage assemblies 70 each of which include an
axially extending center support member 74 and a plurality of
annular shaped mas~age elements 72 are mounted axially on and
rotatable about the center support members 74. The ends of each
center support member 74 in side wall 40 of Figure 1 are iden-
tified by numerals 76 to 86. As is apparent from Figures 1 and
2, the center ~upport members are mounted on an arcuate, spaced
parallel alignment between the spaced, parallel planar side sup-
port members 38 and 40 and above the base support 22. Each of
the plurality of massage asaemblies 70 are also located above the
opposed surace 32 ol: base plate 24.
In order to insure that the massage elements 72 do not extend
beyond the housing means 20, the radius of the spherical massage
element 72 extend from the center support member 74 to below the
ramp`support surfaces 66 and 68.

The plurality of message assemblie~ 70 together form an
arcuate shaped, which is generally convex, treating surface. The
treating surface is angularly di6posed and extends between the
substantially parallel side support members 38 and 40.
In the preferred embodiment illustrated in Figures l and 2,
the base plate 24, which i5 integral with the base support 22,
has affixed to the substantially planar surface 30 a resilient
covering 90 which has a plurality of substantially parallel
protruding members extending therefrom. A user, when utilizing
the combined foot massage and support as shown in Figure 2, has
a resilient support for the feet.
In Figures 3, 4, and 5 the convex treating ~urface formed by
the massage elements 72 of the plurality of massage
a0semblies 70 is readily apparent. The angle of the convex
shaped treating surface permits a user to place the arch of a
foot over the convex shaped massage assemblies 70 to massage the
foot. A handle 92 is provided to lift and/or reverse the posi-
tion of the foot massage an~ ~upport.
As illustrated in Figure 1, the foot massage and support 20
has a ma~sage portion wherein the base support 22, the substan-
tially planar surface 30 of th~ ba~e plate 24 and the substan-
tlally planar support surfaces 60 and 62 of the side support
members ~8 and ~0, respectively, are positioned on a 0upporting
0urface .
In the massage position, the convex shaped, angularly
disposed treating surface is adopted to receive the feet of user
which may be massaged by movement of the feet relative to the
rotatably mounted massage elements 76. A dashed foot 88
illustrate~ that the preferred size of the massage element~ 70 is
that two of the elements are sufficient to support the foot 88.
In Figure 5, the preferred ergonomic design angle is about
10 to about 20.

The present invention has wide utility in both industrial and
health applications. The present day trends in the computer and
production fields generally require a human being to spend
substantial time in a sitting position. Accordingly, the
fatigue, stress and di~comfort of a human being is greatly
reduced by elevating the feet, legs and thighs. As a result
thereof, the duration span, comfort and health of a user is
substantially improved by application of the ergonomic principles
to the combined foot massage and foot rest.
In addition, the foot massage treating ~urface ha~ theraputic
value, that is, by massage of the feet of a user at the preferred
071983-837.1
