Description
FIELD OF THE INVENTION
[0001] The present invention relates to exercise mats and, in
particular, to exercise mats that are particularly well-suited to
yoga.
BACKGROUND OF THE INVENTION
[0002] Yoga is practiced worldwide as both a form of spiritual and
physical development. In the West, Yoga is most often practiced as
a form of exercise that develops and tones the muscles, increases
flexibility and strength, improves balance and promotes overall
health and well-being. Circulation is also increased and the nerves
are ensured a supply of nutrients and oxygen.
[0003] The Yogic physical exercises are called Asanas, a term which
means "steady pose." By way of example, in one form of yoga some
basic postures include: headstand, shoulderstand, plough, fish,
forward bend, cobra, locust, bow, spinal twist, crow pose, and
peacock pose, standing forward bend, and triangle. The names of
these poses indicate that much bending and stretching is
involved.
[0004] The routine is typically done on a floor, and poses are
normally held for some time. It is therefore common to use a yoga
mat or rug during a yoga routine. However, many of the yoga mats
currently in use do not provide optimal support to the user, or do
not provide optimal comfort. Consequently, it would be desirable to
have improved mat options for the yoga practitioner.
SUMMARY OF THE INVENTION
[0005] In one embodiment, an exercise mat for yoga has a lower
non-slip layer, a middle cushion layer, and an upper layer. The
upper layer has knobs on its outer surface to provide acupressure
support to a user. Side layers are interconnected with the upper
and lower layers to encompass the middle cushion layer.
[0006] In accordance with optional aspects of the embodiment, the
middle cushion layer may be made of foam. The foam may be any type
of foam known in the art for mats, or may be a specialized foam
such as memory foam. As an alternative to foam, the cushion layer
may be formed from cotton batting, hulls, or other cushioning
material. The upper layer may be molded rubber. The knobs may be
integral to the upper layer, or may be separately attached.
[0007] In one embodiment, the mat is divided into foldable
sections. The sections may be divided by seams, such as sewn seems,
interlocking seems, or other seems known in the art.
[0008] Considering another embodiment, an exercise mat for yoga may
have a lower non-slip layer, a middle cushion layer, an upper
layer, and side layers interconnected with the upper and lower
layers to encompass the middle cushion layer. In all of the
embodiments, the lower, upper and side layers may be one continuous
sheet of material, if desired, that is welded or otherwise
connected together.
[0009] In another embodiment, an exercise mat for yoga has a lower
non-slip layer, at least one foam middle cushion layer, and an
upper layer that has integral knobs on its outer surface, to
provide acupressure support to a user. Side layers are
interconnected with the upper and lower layers to encompass the
middle cushion layer. The exercise mat also has foldable
sections.
[0010] Generally, the present invention encompasses a variety of
improved mat designs, including sectioned mats that fold, mats that
are cushioned with memory foam, mats that have knobs or similar
protrusions on (or beneath) the upper surface in order to provide
acupressure, and/or any combination of these elements.
[0011] Other variations are possible, including providing a foam
layer that has a pattern on its surface, such as a wave pattern, an
undulating pattern, an egg crate pattern, or the like, to provide a
specialized cushioning to the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] The present invention relates to various embodiments of
optimal yoga mats for improved balance, stability, relief of joint
and knee pain, and/or improved grip. Certain embodiments also
provide specific advantages, such as providing acupressure to the
exerciser, and/or utilizing memory foam, and/or dividing the mat
into hinged sections so as to be foldable.
[0020] Considering now a first embodiment, FIG. 1 illustrates yoga
mat 10 having four sections: 12a, 12b, 12c, and 12d. Although this
mat is shown having four sections, it is possible to have any other
number of sections, such as three, four, six, or eight sections.
Consequently, the specific number of sections in the mat can be
varied depending upon the desired characteristics of the mat.
[0021] The sections are divided by joints 14a, 14b, and 14c. These
joints may be any of the number of different forms. The joints may
be, for example, seams formed by sewing the top and bottom layers
together. Alternatively, the top and bottom layers may be fused
together at the fold seams, as by heat welding or other type of
welding, or with an adhesive. The seams may also be hinged, as by
an interlocking hinge or by other hinges suitable for use on a
folding mat.
[0022] FIG. 2 is a cross-section taken about line 2-2 in FIG. 1.
FIG. 2 shows that the upper surface 16 of the mat 10 includes
various knobs or "bumps" 18. The knobs 18 may be an integral part
of a top layer 20, which may be made out of any of a number of
materials. For example, the upper layer 20 may be made of rubber,
latex, plastic, or other moldable material.
[0023] Alternatively, the upper layer 20 may be a composite formed
from an upper sheet having knobs attached thereto, such as by
sewing, gluing, or other attachment method known in the art. For
example, the knobs 18 may be made, in one embodiment, from metal,
which is attached to an upper layer (for example, rubber) by way of
an adhesive or other known means.
[0024] Most typically, the upper surface 16 will be formed of an
integral layer of molded material, which may be made with standard
injection molding equipment or other equipment known in the art.
The knobs may be circular in shape, elliptical, square,
rectangular, pointed, or a mixture of different shapes. In one
embodiment, the knobs are a uniform height across the upper
surface. In another embodiment, however, the knobs vary in height
to provide a non-uniform upper surface.
[0025] Also, the knobs may be arranged in patterns atop the
surface, so as to support certain portions of the anatomy during
use. That is, there may be knobs concentrated in a central portion
of the mat, for example, with fewer knobs elsewhere on the mat.
Also, the density or size of the knobs may increase in certain
areas of the mat, to improve the function of the mat. Other
patterns of knobs may be made, as desired.
[0026] FIG. 2 also shows a central layer 22, which typically
provides the primary cushioning of the mat. Layer 22 may be made
from any of a variety of materials, most commonly foam. In one
embodiment, the layer 22 may be a memory foam, which is known in
the art as a special foam that provides specialized comfort and
support.
[0027] Memory foam is made from polyurethane with additional
chemicals that add to its viscosity level, thereby increasing the
density of the foam. It is often referred to as visco-elastic
polyurethane foam. Memory foam is available commercially under the
name Tempur-Pedic.RTM.. A variety of different densities may be
used, such as the 4 pound density memory foam. In one embodiment,
the memory foam is up to two inches thick, although thinner layers
may be used.
[0028] The foam layer 22 may be provided as a single layer, or may
be provided as multiple layers stacked atop one another. The foam
layer may also be, for example, a bonded foam. As a further
alternative, the layer 22 may be a material other than foam, such
as cotton.
[0029] A bottom layer 24 is typically made from a material known in
the art for yoga mats, particularly a material that has non-slip
and/or sticky properties. The material 24 may be, for instance, a
sticky material that temporarily adheres to the floor during
exercise in order to prevent movement of the mat during exercise.
Non-slip materials for yoga mats are known in the art.
[0030] Considering now FIG. 3, and taking into consideration the
embodiment of FIG. 1, the mat 10 may be folded when not in use so
as to store the mat. FIG. 3 shows the mat 10 in a folded
configuration in which the four sections of the mat are stacked
atop one another. FIG. 3 is somewhat simplified, although it
clearly shows the sections folded atop one another. FIG. 3 is
simplified in the sense that any of a variety of different types of
joints 14a, 14b, or 14c may be used.
[0031] FIG. 4 illustrates an alternative method of storing a yoga
mat according to the present invention. In FIG. 4, the mat is
rolled rather than folded. This type of storage would most commonly
be used in embodiments in which the mat is not divided into
sections. That is, the mat may be provided with knobs 20 as shown
in FIGS. 1 and 2, but not have the joints 14a, 14b, or 14c. With
that configuration, it is most convenient to store the mat by
simply rolling it up.
[0032] FIG. 5 illustrates a second alternative embodiment, in which
the knobs or protrusions are formed within a mat 110 rather than on
the upper surface. In FIG. 5, an upper cushioning layer 122 has an
undulating pattern 124 in order to provide an uneven upper surface
to the foam. This undulating pattern may be in the form of multiple
waves, or may be in the form of an egg crate pattern.
[0033] The foam layer 122 may be a resilient foam known in the art,
or may be a special memory foam, when desired. In the embodiment of
FIG. 5, a second layer of foam 126 underlies the upper layer of
foam 122. The lower layer of foam 126 may be a solid foam sheet, of
standard resilient foam known in the art and/or memory foam. In one
configuration, either the upper or lower layer of foam 122 is not a
memory foam, but is rather another type of foam known in the art.
However, the lower layer 126 may be a special foam, such as memory
foam, in order to improve the function of the mat. Alternatively,
standard foams known in the art may be used for both layers.
[0034] In the embodiment of FIG. 5, the outer layer 128 on the top
and layer 130 on the bottom may be made of any standard material
known in the art for yoga mats. For example, layers 128 and 130 may
be made of a non-slip material, for example. Alternatively, the
bottom layer 130 may be made of a non-slip material, while the
upper layer 128 may be a particularly thin and compliant material
such as fabric, in order to improve the function of the undulating
pattern atop the upper layer of foam 122. As a further alternative,
both the upper layer 122 and the bottom layer 126 of foam may both
have an undulating or other type of uneven surface, when
desired.
[0035] FIG. 6 is an embodiment in which the upper surface has no
knobs or irregularities, and is generally flat, although the
surface may have some slight texture, if desired. In FIG. 6, there
are multiple sections as in the embodiment of FIG. 1. However,
these multiple sections 212a, 212b, 212c, and 212d may be filled
with pieces of foam having flat upper and lower surfaces, and/or
with multiple layers of foam stacked atop one another. This foam
may be any of the foams known in the yoga mat art, and may be of
standard thicknesses, as desired. An advantage of the specific
embodiment of FIG. 6 is that the sections may fold atop one another
for storage, to create a configuration such as that shown in FIG.
3.
[0036] As a further embodiment, FIG. 7 illustrates a yoga mat 310
having no separate sections, but rather having one continuous sheet
of foam therein. The foam may be of memory foam, or of other foam
known in the art of yoga mats. The embodiment of FIG. 7 may
alternatively have multiple knobs on the upper surface, as in FIG.
2, in order to provide specialized acupressure. Typically in this
arrangement the upper layer will be made of rubber or latex or
other covering known in the art of yoga mats.
[0037] As a further alternative, FIG. 7 may illustrate a mat having
no central layer of foam but, rather, being a single solid material
such as latex or rubber. The mat may have no outer cover or,
alternatively, may be provided with any mat cover known in the
art.
[0038] Those skilled in the art will recognize a variety of
different materials that can be employed. For the cushioning,
materials such as memory foam, closed-cell PVC vinyl material, open
cell foam, neoprene, rubber, latex, microfiber cushion, cotton
batting, kapok and hull filling and/or a variety of other materials
known in the art may be employed. The outer surface of the mat may
be a known material that provides a high-tack surface, such as
latex for example, particularly for the lower covering to prevent
slipping on the floor. Alternatively, other covering
materials--including natural materials such as cotton, a jute
fabric/rubber mix or many other materials--may be employed.
[0039] As further alternatives, the yoga mat may have built-in
carrying handles to eliminate the need for a separate mat bag.
Also, the mat may be covered in a waterproof material for outdoor
use. The mat may come in any of a wide variety of colors.
[0040] As a matter of terminology, "knob" as used in the claim
means a protrusion of any shape or size. In specific embodiments,
the knobs may be fairly tall, such as 1/4'', 1/2'', 1'', or 2''
high, for example, and 1/8'' to 2'' in width. In one embodiment,
the knobs are 1/2'' wide by 1/2'' tall, which provides an
acupressure effect that mere surface roughness could never
approximate.
[0041] It will be apparent from the foregoing that the present
invention provides new and improved embodiments of yoga mats,
providing balance, stability, relief of joint pain, and/or
acupressure. The folding feature of the mat offers convenience to
carry or transport the mat, as well as to travel with it. While the
invention has been illustrated and described herein in terms of its
use relative to yoga, it will be apparent to those skilled in the
art that the invention can be used in other endeavors, such as
stretching exercises.
[0042] While particular forms of the invention have been
illustrated and described, various modifications can be made
without departing from the spirit and scope of the invention.
Accordingly, it is not intended that the invention be limited,
except as by the appended claims.
