Method of swinging on a swing
A method of swing on a swing is disclosed, in which a user positioned on a
standard swing suspended by two chains from a substantially
horizontal tree branch induces side to side motion by pulling alternately
on one chain and then the other.

The present invention relates to a method of swinging on a swing.
BACKGROUND OF THE INVENTION
A few basic types of swings have been around for generations. Perhaps the
most common is one that includes a seat suspended between
two ropes or chains that are hung from a tree branch or other
substantially horizontal support. These swings are often found in
side-by-side sets of two or three or more on, for example, a school
Young children often need help to climb onto a swing, and may need a push
(sometimes even an "underdog" push) to begin swinging.
Others may be able to begin the swinging movement on their own by pushing
with their feet against the ground, and once moving may
coordinate the motion of their legs and body in what may be called
"pumping" to sustain the movement of the swing. When swinging in
this manner, the user travels along a path as generally shown in the
cross-section of FIG. 1. Another method of swinging on a swing
involves twisting the seat around repeatedly so that the chains or ropes
are wound in a double helix. When allowed to unwind, the swing
spins quickly, which can be entertaining for the user.
These methods of swinging on a swing, although of considerable interest to
some people, can lose their appeal with age and experience.
A new method of swinging on a swing would therefore represent an advance
of great significance and value.
SUMMARY OF THE INVENTION
In accordance with one embodiment of the present invention, a method is
provided for swinging on a swing. The swing comprises a seat
for supporting a user that is suspended between two chains that are hung
from a substantially horizontal tree branch. The method
comprises the steps of: a) positioning a user on the seat; and b) having
the user pull alternately on one chain to induce movement of the
user and the swing toward one side, and then on the other chain to induce
movement of the user and the swing toward the other side, to
create side-to-side motion. In another embodiment of the invention, the
swinging method may be practiced independently by the user to
create the side-to-side motion from an initial dead stop. These and other
features of the invention are described in greater detail below.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematic top view of the swinging path of a swing used in
accordance with conventional swinging methods.
FIG. 2 is a front view of a swinging path of a swing used in accordance
with one embodiment of the swinging method of the present
FIG. 3 is a schematic top view of a swinging path of a swing used in
accordance with a second embodiment of the swinging method of
the present invention.
DETAILED DESCRIPTION OF THE INVENTION
The present inventor has created, through experimentation on a standard
swing, a new and improved method of swinging. The swing is
of the type described above, in which a seat is suspended between two
chains that are hung from a substantially horizontal tree branch.
As is apparent to those of ordinary skill in the area of swinging, the
chains could be replaced with ropes, cables, or the like, or the tree
branch could be replaced with another substantially horizontal support
such as a metal bar or pole.
The standard swing should be a single swing that is suspended sufficiently
far away from obstructions to make the practice of the
inventive swinging method completely safe. That is, the swing should be
suspended a sufficient distance away from the trunk of the tree
from which it suspended, and from any other swing, building, support,
overhead wire, or other obstruction or threat to safety that may
The standard method of swinging on a swing is defined by oscillatory
motion of the swing and the user along an axis that is substantially
perpendicular to the axis of the tree branch from which the swing is
suspended. This "forward and back" movement has been known for
generations, and is illustrated in FIG. 1. In contrast to the conventional
method of swinging, the present inventor has discovered that
much greater satisfaction can be obtained by alternately pulling on one
chain to move the swing and the user toward that side, and then
pulling on the other chain to move the swing and the user toward that
side. This side-to-side oscillatory motion of the swing and the user
is thus along an axis that is substantially parallel to the axis of the
tree branch from which the swing is suspended, and is illustrated in
FIG. 2. This side to side swinging method has the added benefit that it
can be continued for long periods of time simply by alternately
pulling on one chain and then the other. The importance of sufficient
clearance between the swing and any obstructions or threats to the
user's safety is apparent.
The present inventor has discovered certain other improvements in the art
of swinging on a swing, either or both of which can be used in
conjunction with the swinging method described immediately above. The
first is that the inventive swinging method can be initiated from
a dead stop without pushing, and without the user having to contact the
ground. That is, the user can climb onto the swing, and begin
from an initial dead stop to pull first on one chain, and then on the
other chain, alternately until the user and the swing have begun to
swing side-to-side in accordance with the inventive swinging method
described herein. This enables even young users to swing
independently and joyously, which is of great benefit to all.
Another improvement on the swinging method described above is the
induction into the side-to-side swinging movement of a component
of forward-and-back motion. That is, by skillful manipulation of the body,
the present inventor has found it possible to add a relatively
minor component of forward-and-back motion to the side-to-side swinging
motion, resulting in a swinging path that is generally shaped
like an oval, as is shown in FIG. 3. It is preferred that the magnitude of
the forward-and back motion (shown in FIG. 3 as being along
the Y axis) be less than the magnitude of the side-to side motion (shown
in FIG. 3 as being along the X axis), so that the latter
predominates. In this manner, the motion can be more easily continued
simply by alternately pulling on one chain and then the other in
the manner described.
Lastly, it should be noted that because pulling alternately on one chain
and then the other resembles in some measure the movements one
would use to swing from vines in a dense jungle forest, the swinging
method of the present invention may be referred to by the present
inventor and his sister as "Tarzan" swinging. The user may even choose to
produce a Tarzan-type yell while swinging in the manner
described, which more accurately replicates swinging on vines in a dense
jungle forest. Actual jungle forestry is not required.
Licenses are available from the inventor upon request.
