NECK EXERCISE DEVICE
DESCRIPTION
BACKGROUND OF THE INVENTION
Field of invention
The neck is one of the body's most flexible joints. Due to the mobility
required of the neck,
and the load the neck must carry, a complex arrangement of muscles, tendons,
ligaments,
and soft tissue are involved in supporting the head and absorbing shock in
this area of the
body. As part of the neck's normal daily function, neck movement includes
rotation, flexion,
extension, lateral bending, and combinations of all these movements. The neck
muscles
are easily strained if they are not sufficiently strong. Neck muscles are very
susceptible to
injury or other painful problems from a variety of sources, including jarring
motion from
motor vehicle accidents or contact sports; posture-related fatigue, and
emotional stress.
When the head is suddenly jerked in one direction without warning, as in a
motor vehicle
accident or in a contact sport, the neck muscles contract in spasm, which
holds the muscle
in a foreshortened position, and causes pain and interference with neck
function and
posture. When office workers sit for long hours at a desk or in front of a
computer, they
suffer neck fatigue due to improper posture, inactivity, and poor circulation;
which can
adversely affect a person's performance.
Furthermore, many people store emotional tension in the neck, which can result
in
headaches, sleeplessness, and even spasm when the tension does not get
released.
There are common techniques employed in the rehabilitation of spasm and
general muscle
tension. Isometric contraction (where the force exerted by the muscle matches
the
resistance offered and movement does not occur), has been shown to induce a
relaxation
in the antagonist muscle group, and lessen the degree of spasm. Isotonic
contraction
(where the force exerted by the muscle overcomes resistance and movement does
occur),
has been shown to retrain weak muscles to normality, increase circulation, and
in effect
flush inflammation and tension from a muscle. Neither approach calls for heavy
loading. In
all cases the resistance is less than the muscle is capable of overcoming.
CA 3070329 2020-01-30

2
A need has thus arisen for an exercise device for use on a daily basis to
rehabilitate,
develop, and strengthen the muscles of the neck and the surrounding area,
affording the
usage of both isometric and isotonic techniques; employing a safe, limited
resistance.
A need has further arisen for an exercise device to allow neck injury
sufferers to perform
light exercise, either isometric or isotonic, especially with the injured
muscle or its
antagonist in isolation, to reduce spasm, relieve pain, and enable an injured
patient to
return to normal activities of daily living. As the injury heals, continued
exercising, with
slightly more resistance, employing complex movement, can be prescribed to
strengthen
the surrounding muscles, improve posture, and help prevent recurrence of
injury.
A need has further arisen for a simple, portable, inexpensive, and safe device
that can be
prescribed for rehabilitation and ongoing general neck wellness.
Description Of Prior Art
One of the known devices used in the prior art for exercising the human neck,
involves the
use of a series of straps of cloth material which are sewn or otherwise
secured together to
form a hat-like pocket for cradling the head of the person whose neck is to be
exercised.
Portions of the straps are arranged to depend from the hat portion of this
prior art device
so as to extend substantially below the neck and shoulders of the person
performing a
neck exercise routine but not, typically, below the waist of such user. The
ends of such
straps terminate in loops for anchoring suitable weighted objects thereto.
The use of this prior art neck exercising device involves placing the hat
portion over the
head of the person whose neck is to be exercised, affixing one or more
weighted objects to
the looped portions of the depending straps and thereafter moving the neck up
and down
and side to side. The weighted objects provide a constant pull or "force"
which is
transmitted to the user's neck via the depending straps and the hat structure
formed by the
sewn straps. The neck is thereby exercised along with the muscles of the human
body
which are associated with the movement of the human neck. At least one
deficiency with
this prior art device lies in the inability of the user to comfortably stand
up and exercise his
neck; the contact of the weighted objects with his body is in some cases
intolerable and in
other cases, simply a nuisance and a source of irritation.
Another prior art neck exercising device includes an upright frame capable of
surrounding
the upper torso of a person. This device includes: a pair of handles manual
gripping of the
frame, a plurality of weighted objects, and some flexible ropes. One end of
each rope is
CA 3070329 2020-01-30

3
secured to one of the weighted objects. The device further includes guide
means secured
to a frame for guiding each of the plurality of ropes; means for securing the
ropes to the
weighted objects; and means for securing the unattached ends of the ropes to
the head of
the person using the device.
The use of this prior art device relies on movements of the weights which are
intended to
strengthen the neck. This device, however, can present problems when used by
patients
with a herniated disc. The weights can cause additional compression of the
cervical spine
and therefore, possibly exacerbate the injuries of the cervical spine. In
addition, the use of
the frame is cumbersome and a nuisance.
At this time, there is a continuing need for a device for exercising the
cervical spine as it
relates to rehabilitation of injuries to the cervical spine, deformities of
the cervical spine
and disease of the spine affecting the neck area. There is also a need for
strengthening
soft tissues and ligamentous tissues, such as the anterior, posterior and left
and right
lateral longitudinal ligaments of the cervical spine. A device is especially
needed when
these areas have been exposed to trauma and injury has resulted. A device is
also needed
for those people suffering from a weakness in the cervical spine from other
causes other
than trauma. Especially needed is a device which can address the above needs
while
depending solely on isotonic responses (without weights) to natural movements,
and
allows the person to use the device while engaging in almost any type of
activity. Such a
device would an improvement over the prior art and is described herein.
SUMMARY
This device is based from the foundation of a padded cotton strap with Velcro
one wrap tie
on top of the head band and back of the head band as adjusting and fastening
system.
That provides the nucleus for which this device is constructed, manufactured
and utilized.
In order for this device to be used as intended, a Velcro one wrap tie
material is attached
to the end of the cotton strap on top of the head to adjust and fasten
vertically and on the
back of the head to adjust and fasten horizontally around the head of the
user. Velcro one
wrap tie portion on one side and a single loop slider ring on the other side.
The Velcro one
wrap tie tip threads through the loop slider and wrap it onto itself, then
becomes the
element with which this exercise device is to be properly positioned and
secured in place
for use. Attached to this cotton strap on the outer parameter circumference at
four
separate opposing points are double "D" configuration rings and tow nylon
webbing strap
