Ergonometric pushup wedge
Abstract
A pushup wedge. The pushup wedge is made of an elastomeric
material with a density in the range of about 25 kg/m.sup.2 to
about 150 kg/m.sup.2 and has a generally wedge shape with a sloping
top that slopes between about 5 and 20 degrees from the horizontal
from a lower front portion to a higher rear portion, wherein the
rear portion has a generally curved contour. A retention strap can
be further included that passes over sloping top, which retention
strap is adapted for retaining a user's hand between the strap and
the sloping top.

Description
SUMMARY
[0001] The invention relates to the field of exercise, sports and
training equipment, and more particularly to ergonometric push up
wedges to help ease the stress on a person's wrists as he or she
does push ups and other similar exercises.
[0002] Push ups are a basic exercise incorporated into many
exercise and physical fitness programs and routines. In standard
pushups, a person will position his or her body generally
horizontally and straight, with the full body weight carried on the
toes and hands placed on the ground, and arms fully extended
straight (the starting position). From this position, the person
will lower the torso to touch his/her chest to the ground, and then
fully extend the arms to raise the body back to the starting
position. By changing the level of the feet relative to the torso,
the level of difficulty of the exercise can be varied. For example,
some exercisers like to place their feet on a chair for an extra
vigorous workout, while others will lean against a wall or pivot on
their knees rather than their toes for less strenuous exercise.
[0003] Regardless of the particular style used, one complaint that
many people have with pushups is that they can be uncomfortable or
put extra stress on the palms, fingers and particularly wrists of
the exerciser.
[0004] Numerous devices have been developed with the goal to make
pushups more comfortable. For example, there are devices that
comprise a pair of stands with horizontal padded grips which a user
can grip while doing pushup. There are also devices that comprise
padded bars that can be grasped while doing push up. However, with
these devices, the push up posture is not ideal.
[0005] There remains a need for an ergonometric device that makes
doing push up more comfortable, productive and biomechanically
correct.

DETAILED DESCRIPTION OF THE INVENTION
[0017] Turning to FIGS. 1 to 4, there is shown view of an exemplary
push up wedge 10 of the invention, with FIG. 1 being a front
isometric view, FIG. 2 being a side view, FIG. 3 being a front
view, and FIG. 4 being a bottom view of the exemplary push up wedge
10. The push up wedge 10 has a top surface 12, a front 14, a rear
16, left and right sides 18 and 20, and a bottom surface 22.
Although the exemplary wedge 10 is shown with its front side 14 and
rear side 16 having four planes 14a, 14b, 14c and 14d, and 16a,
16b, 16c and 16d, respectively, the wedge 10 can have a greater or
lesser number of less sides, and can be curved, flat, be contoured
to fit a user's fingers and the like. The top surface 12 is shown
as having planes 12a, 12b and 12c to provide an arched shaped top
surface to better cup a user's palm. However, the top surface 12
can be made in a curved or other contoured shape to better fit a
user's palm, or can be flat. The wedge 10 is preferably constructed
of material that somewhat soft and conforming to the hand under
pressure, yet is sufficient firm and resilient such that the wedge
does not collapse under normal use. Materials such as ethylene
vinyl acetate (EVA) foam function well, and can have a density in
the range of about 25 kg/m.sup.2 to about 150 kg/m.sup.2, and more
preferably in the range of about 42 kg/m.sup.2 to 140 kg/m.sup.2,
and even more preferably in the range of 65 kg/m.sup.2 to 85
kg/m.sup.2 with the particular density and resilience, and with
hardness measured on a shore 00 scale ranging from 40.+-.10 to
50.+-.10, such as provided by Engineered Plastics, Inc. of
Gibsonville, N.C. 27249, selected based on the body weight ranges
of people who will be using the wedge 10. For example, #2 EVA
offered by Engineered Plastics, Inc. a density of 0.032.+-.0.008
g/cm.sup.3 (2.+-.0.5 lb/ft.sup.3); #3 EVA, a density of
0.048.+-.0.008 g/cm.sup.3 (3.+-.0.5 lb/ft.sup.3); and #4 EVA, a
density of 0.054.+-.0.008 g/cm.sup.3 (4.+-.0.5 lb/ft.sup.3). In
addition to EVA foam, the wedge can also be constructed out of
multicellular expanded resinous foam material (such as
Styrofoam.RTM.), padded and unpadded wood and/or plastics, or other
materials. The top surface could also be textured or covered in
material with friction enhancing textures and finishes, which would
make the surface less slippery. In general, the material should be
selected to provide sufficient cushioning to a user's hands and
wrists, to prevent stress thereon.
[0018] FIG. 5 is a diagrammatic view of a wedge 10 of the invention
and shows three slants of the upper surface 12a, 12b, and 12c,
which slant upwardly from the horizontal from the front 14 to the
rear 16 by about 2.5.degree. to 20.degree.. The inventors have
found that a slant of the upper surface 12b of about
10.degree..+-.2.5.degree. from the horizontal is a comfortable
angle range for most users who are healthy and uninjured, as shown
in solid line 12. The slant can be increased to about
15.degree..+-.2.5.degree., e.g., for orthopedic users who desire
less stress on their hands and wrists and desire a more comfortable
posture, as shown in large dashed line 30. For users who wish a
more strenuous posture (a "pro" embodiment"), the slant can be
decreased to about 5.degree..+-.2.5.degree., from the horizontal,
as shown in small dashed line 32.
[0019] Table 1 list some exemplary push up wedge dimensions for a
"normal" 10.degree. slant of the top surface 12. TABLE-US-00001

[0020] FIGS. 6 and 7 are a top and isometric view of another
embodiment of the push up wedge 40 that has a curved front walls 42
and curved rear wall 44, side walls 46 a flat top surface 48. The
top surface 48 can be contoured instead of flat if desired. The
push up wedge 40 has a bottom surface 49 for placement on a floor.
In actuality, the pushup wedges can be used with either the top
surface or bottom surface facing up for contact with a user's
palms.
[0021] FIG. 8 is isometric view of yet another embodiment of the
push up wedge 50 that is similar to the push up wedge of FIGS. 6
and 7, and has a curved front walls 52 and curved rear wall 54,
side walls 56 a top surface 58. The top surface 58 can be contoured
instead of flat if desired. A retention strap 60 is provided on the
pushup wedge which makes the device very easy to retain on a user's
hands. This feature is very convenient for certain exercises, for
example, such as military style 8 count push ups where a user
starts from a standing position, touches the floor in front of
his/her hands, hops his/her feet back for a straight leg posture
with his/her back straight in a pushup position, dips with a
straight back, dips with a straight back again, hops his/her feet
back closer to his/her hands touching the floor, and then stands
up. The retention straps 60 will help prevent the user from
dropping the pushup wedges at an inappropriate time. Besides a
strap, other shapes, such as cords, integral loops or handholds,
etc. formed from the resilient material are also useable.
[0022] FIG. 9 is a rear isometric view of a further exemplary push
up wedge 70 of the invention with a convexly cupped top surface
72.
[0023] FIG. 10 is a front view and FIG. 11 is a side view of the
exemplary pushup wedge of FIG. 9. The convexly cupped top surface
72 shape will provide a smooth and comfortable surface upon which a
user will rest his/her palms during pushups. The front of the
pushup wedge can also be curved if desired.
[0024] In general, the pushup wedges of the invention will provide
cushion for the user's palms and help protect the wrists from undue
stress and strain.
[0025] Having thus described exemplary embodiments of the present
invention, it should be understood by those skilled in the art that
the above disclosures are exemplary only and that various other
alternatives, adaptations and modifications may be made within the
scope of the present invention. The presently disclosed embodiments
are to be considered in all respects as illustrative and not
restrictive.
