Description
BACKGROUND OF THE INVENTION
Training aids and exercising aids for swimmers have been proposed
previously. One device of this type includes a ring which is worn
around the waist of the swimmer and which is suspended from a frame
to support the person while he practices swimming or while he
exercises. Such a device has drawbacks. Since the entire body of
the swimmer is supported, the frame means from which the ring is
suspended tends to become awkward and too bulky for use in home
pools. Also, it is believed that it is unnecessary to support the
entire body of the swimmer for some exercising and training
purposes.
SUMMARY OF THE INVENTION
The present invention is a device which provides floating support
for the head of a person rather than his entire body. Since the
device floats, it need not have a bulky frame nor extensive
anchoring means. Also, the floating action provides inherent
resiliency for following the movements of the person. The preferred
embodiment of the device comprises float means for causing the
device to float in the water, anchor means at one end of the float
means for attaching the device to the side of a pool, and head rest
means on the float means providing floating support for the head of
a person while he exercises or practices swimming with his head on
the head rest means and his body stretched out in the water. The
float means may be pivotally connected to the anchor means to allow
the float means to move pivotally in the water and also to allow
the device to be raised out of the water to a rest position. In one
form of the device, the float means includes both a frame and
floatable members attached to the frame, the floatable tubes being
eccentrically mounted on a portion of the frame and rotatable to
different positions to adjust the level at which the device floats.
The float members may also be axially movable if desired.
Accordingly, it is an object of the present invention to provide a
simpler, less cumbersome device for use by swimmers in exercising
and training than has heretofore been available.
Another object of the invention is to provide a floating exercising
and training aid for swimmers.
A further object of the invention is to enable the device to float
in the water while it is attached to the side of a pool.
Another object of the invention is to allow adjustment of the level
at which the device floats in the water.
A further object of the invention is to enable the device to be
raised out of the water to a rest position at the side of the
pool.
Still another, and no less important, object of the invention is to
make the device useful both for professional purposes and also for
use by novices and children in a home pool.
Other objects of this invention will appear from the following
description and appended claims, reference being had to the
accompanying drawings forming a part of this specification wherein
like reference characters designate corresponding parts in the
several views.

DETAILED DESCRIPTION
The device illustrated in the drawings constitutes one of the
possible embodiments of the invention. The device includes float
means generally designated 20 which, in this embodiment, consists
of a frame 22 in the form of a loop, and float members 24 and 26
mounted on the loop 22. The float means 20 has head rest means 28
at the distal end thereof. At the other end of the float means 20,
the ends 30 and 32 of the loop 22 are pivotally attached to a pivot
means 34 which is carried by anchors 36 and 38.
The anchors 36 and 38 serve to attach the device to the side 40 of
a pool. This may be any kind of a pool--not necessarily a home
swimming pool--but the device is suitable for use in home pools if
desired.
The loop 22 has two generally parallel tubular arms 42 and 44, and
a crossarm 46 (FIGS. 4 and 7) which bends or curves around between
the parallel arms 42 and 44. The head rest 28 consists of the
crossarm 46 and a tubular pad 48 carried on the crossarm.
The pivot means 34 is shown most clearly in FIG. 6, and it may be
seen there that it consists of a rigid rod 50 having tubular
sleeves 52, 54 and 56 on the outside thereof with end caps 58 and
60 over the ends of sleeves 52 and 56. There is a space between
sleeves 52 and 54 and another space between sleeves 54 and 56, and
the ends 30 and 32 of the loop 22 fit in these spaces. The rod 50
extends through openings in the ends 30 and 32 of the loop, and the
openings allow for pivotal movement of the loop on the rod 50 while
the entire float means 20 floats in the water. The pivotal
connection of the float means to the anchoring structure also
allows the entire float means to be raised out of the water to a
rest position against the side of the pool as shown in FIG. 10.
The two float tubes 24 and 26 and the head rest 28 may be made of
foam plastic material which is highly buoyant. The float members 24
and 26 are preferably tubes which are eccentrically mounted on the
parallel arms 42 and 44. The tubes have a friction fit on the arms
42 and 44 so that the tubes will stay in any given position but can
be adjusted to different positions. Thus, in FIG. 2, the tubes are
adjusted to a position wherein the thickest part thereof is above
the water line (WL) and the device floats with the head rest 28
partially submerged in the water. On the other hand, in FIG. 8 the
tubes 24 and 26 have been rotated 180.degree. as compared to FIG. 2
so that the thickest portion of the tubes faces downwardly into the
water. The tubes have also been slid upwardly along the parallel
arm portions 42 and 44. With the float members 24 and 26 in the
position shown in FIG. 8, the float means 20 floats on the water
with the head rest portion 28 raised slightly above the water line.
In FIG. 9, the float tubes 24 and 26 are in the same axial position
as in FIG. 2, but they have been rotated so that the thickest
portion of the tubes faces downwardly into the water. With the
float tubes in this position, the float means 20 floats on the
water with the head rest portion 28 approximately at the water
level. Other positions of the float tubes are clearly possible.
As shown in FIG. 5, the anchor means 36 and 38 may consist of
rubber suction cups 62 and 64 mounted on short rods such as the rod
66 shown in FIG. 5. The rod 66 is fastened to the cup 64 and the
rod 50 with a bolt 68.
Referring to FIG. 7, it may be seen that the bent crossarm 46 which
connects the two parallel arms 42 and 44 together at the distal end
of the device may be a separate curved tubular member which is
fastened to arms 42 and 44 with bolts 70 and 72. It should be clear
that it is not essential to make the crossarm 46 in a curved
configuration and it is also not essential that it be a separate
piece. In fact, it is contemplated that the entire flotation means
could be a single piece of material with the floating structure
built into it.
Thus, the invention provides an aquatic device for use as a
training aid or as an exercising aid which is relatively simple in
construction, versatile in use, and readily marketable. The device
has relatively few parts, and can be manufactured from available
components. Since the device floats on the water, the person may
use the device merely by resting his head on the head rest portion
of the device with his body stretched out in the water from the
head rest portion. A swimmer may float on his back with his head
resting on the head rest and exercise by kicking and paddling with
his arms and feet. Alternatively, the swimmer may place his
forehead on the head rest portion of the device and exercise or
practice swimming in a face down position. When the device is not
in use, it may be elevated to a raised position leaning against the
side of the pool as shown in FIG. 10. The device illustrated in the
drawings has adjustable float tubes which can be set in any of a
variety of positions to regulate the level at which the float means
floats in the water. Since a portion of the device floats, it gives
or yields as the person moves while he practices swimming or
exercises. This makes the device relatively comfortable to use.
