Abstract
A trim and position control device and method comprising a
generally ring-shaped, continuous and unbroken weight formed with a
central elongated opening therethrough. The opening is preferably
shaped like an elliptical diamond and enables placement of the
weight over a pillar valve and pillar valve rotatable pressure
control handle onto the top surface of a diving tank. The bottom
surface of the weight is preferably concave to promote proper
nesting upon the top surface of the diving tank. The weight is
secured in place by the connection of a primary stage regulator to
the pillar valve of the diving tank, wherein the primary stage
regulator is connected to a buoyancy compensator device and second
stage regulator. This prevents the weight from being inadvertently
detached. The weight enables a diver to maintain desired trim and
position in conjunction with the inflation of the buoyancy
compensator device.

Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority to U.S. Provisional Patent
Application No. 61/251,986 filed Oct. 15, 2009, the disclosure of
which is incorporated herein by reference.
FIELD OF THE INVENTION
[0002] The present invention relates to SCUBA diving gear, and more
particularly, to a device and method for promoting proper trim and
position during a dive while underwater and upon surfacing through
the use of a specially formed weight installed on the top of a
diving tank.
BACKGROUND OF THE INVENTION
[0003] It is well known in SCUBA diving that a diver must
compensate for the natural buoyancy of the diver and the buoyancy
of the wet suit typically worn by the diver. This is primarily done
with weights. Additionally, when SCUBA diving, a diver should be
taught that as soon as he reaches a desired depth, he must add a
small amount of air into his buoyancy compensator device ("BC" or
"BCD"), such as shown in U.S. Pat. No. 5,662,433 to Seligman,
incorporated herein by reference, in order to attain neutral
buoyancy. In addition, he should be aware of the importance of
having arranged the weights carried in or on his equipment so as to
achieve the proper trim.
[0004] During the dive, once neutral buoyancy is achieved, a
properly trimmed diver will tend to maintain a horizontal or slight
head-down position. Improper trimming causes the diver to have
trouble maintaining horizontal orientation and, as a result, many
divers tend to rotate toward a vertical upright orientation
affecting their ability to adequately view the sea floor and other
structures and potentially causing the diver's fins to come in
contact with and damage a reef or sea floor. During the equipment
set-up before the dive, transferring an appropriate amount of
weight from the weight belt or weight pocket location to a position
atop the air tank and behind the diver's head will correct this
problem.
[0005] Upon surfacing at the conclusion of a dive, the desired trim
orientation now becomes vertical with the head either upright or in
a slight head-back position. Upon surfacing, the diver should
inflate the air bladder in the BCD. In current BCD designs, an air
pocket tends to be positioned behind the diver's head, resulting in
a near vertical, slight head-forward, nose-down tendency. This is
undesirable for a diver who has taken the regulator out of his
mouth to breathe fresh air because the head-forward position
creates a propensity for the diver to inadvertently aspirate water
causing discomfort and potential panic. The present invention is
secured atop the dive tank and behind the BCD bladder, thus its
weight acts as an opposing directional force and allows the diver's
head to be in a more favorable face-up position.
[0006] Various weighting systems have been developed to address the
trimming problem, wherein weights are attached to the diver's BCD
or to the diving tank. These weights are all designed to be easily
detachable underwater. A resulting problem with prior art weighting
systems designed for attachment to diving tanks is they are prone
to accidental detachment, and an unexpected loss of weight can
result in frustration with trimming or a dangerous rapid rise to
the surface which can cause injury or death.
[0007] Accordingly, what is needed is a weight that can be used to
promote proper trim and position during a dive while underwater and
upon surfacing, and cannot be inadvertently detached.
SUMMARY OF THE INVENTION
[0008] The current invention is an improvement over prior art
weighting systems in that it cannot be accidentally detached, it
does not require any adjusting during the dive, and it promotes
both the proper horizontal trim and position needed at depth and
the proper vertical trim and position needed upon surfacing. More
particularly, the current invention is a SCUBA diving trim and
position control device and method comprising a generally
ring-shaped, continuous, unbroken weight formed with a central
elongated opening. The opening is preferably shaped like an
elliptical diamond with a long axis and a short axis. The weight
preferably has a bottom concave surface and a flat top surface.
[0009] Due to the design of the opening of the weight, in a
preferred embodiment the weight should normally only be able to be
placed over a pillar valve and pillar valve rotatable pressure
control handle with the long axis of the opening of the weight in a
parallel plane with the pillar valve and rotatable control handle
of the tank. However, for example, an alternate design of a weight
with an opening in the shape of a circle would function, but it
would have several drawbacks including less stability of the weight
on the tank.
[0010] In use, the weight is placed over the pillar valve of a
diving tank and onto the top surface of the diving tank. It can
then be rotated 90 degrees to take advantage of the short axis of
the weight opening for purposes of securing the weight underneath
the pillar valve rotatable pressure control handle. A primary stage
regulator is then attached to the pillar valve, wherein the primary
stage regulator is connected to the BCD via a first hose and to a
breathing regulator via a second hose. The primary stage regulator
can also be attached to other devices, such as a pressure gauge and
back-up breathing regulator via additional hoses. Thus, the weight
is secured in place, thereby enabling a diver to maintain proper
trim in conjunction with inflation of the BCD while avoiding
inadvertent detachment of the weight.
[0011] The method and device of the present invention may be
achieved at low cost especially due to the invention using inherent
properties and qualities already present on a diving tank and a
primary stage regulator, thereby eliminating the use of an
additional fastening system for the weight.

DETAILED DESCRIPTION OF THE INVENTION
[0024] The present invention, shown in FIGS. 1-12, is an unbroken
ring-shaped weight and the use of the weight for SCUBA diving.
Referring to FIGS. 1-9, a preferred embodiment of the weight 10 is
shown with an opening 12 therethrough. The weight 10 preferably has
a flat top surface 14 and a bottom concave surface 16. The weight
10 is preferably polygonal in overall shape with the opening 12
having an elliptical diamond shape. The opening 12 has a long axis
A and a short axis B. The weight 10 is preferably coated with a
coating 18 that protects the weight 10 and cushions the weight 10
when secured atop the diving tank 20. The coating 18 is preferably
a soft plastic coating having a frictional effect to resist sliding
when secured atop the diving tank 20.
[0025] Referring to FIGS. 10-12, the weight 10 is shown being
placed onto a diving tank 20 and secured thereto. Specifically,
FIG. 9 illustrates a diving tank 20 having a pillar valve 22 and a
pillar valve rotatable pressure control handle 24. The weight 10 is
placed over the pillar valve 22 and control handle 24 by aligning
the long axis A of the opening 12 over the pillar valve 22 and
control handle 24. FIG. 10 illustrates the weight 10 on the top
surface of the diving tank 20 and being rotated ninety degrees for
purposes of securing the weight 10 underneath the pillar valve 22
and control handle 24. FIG. 11 illustrates the assembly of a
buoyancy compensator device 26 fastened to the diving tank 20. The
weight 10 is further secured to the tank by the attachment of a
primary stage regulator 28 having a rotatable pressure control
handle 34 to the pillar valve 22, wherein the primary stage
regulator 30 is connected to the buoyancy compensator device 26 via
a first air hose 30 and to a secondary stage breathing regulator
(not shown) via a second air hose 32.
[0026] Accordingly, the present invention comprises a SCUBA diving
trimming and position control device and method of using the device
with a diving tank. The device is preferably an elliptical,
circular, or polygonal shaped weight 10 having an unbroken and
continuous member and an elongated opening 12 therethrough
generally shaped like an elliptical diamond having a short axis B
and long axis A, thus allowing the weight 10 to be placed over a
pillar valve 22 and pillar valve rotatable pressure control handle
24 of a diving tank 20. The weight 10 preferably has a flat top
surface 14 and a bottom concave surface 16 to promote proper
nesting upon the top surface of the diving tank 20.
[0027] In use, the weight 10 is placed over the pillar valve 22 and
onto the top surface of the diving tank 20. The weight 10 is
preferably rotated ninety degrees to trap it under the pillar valve
22 and pillar valve rotatable pressure control handle 24 by way of
the opening's 12 short axis B. A primary stage regulator 28 is then
attached to the pillar valve 22, wherein the primary stage
regulator 28 is connected to a buoyancy compensator device 26 via a
first air hose 30 and to a secondary stage breathing regulator (not
shown) via a second air hose 32. The primary stage regulator 28 and
the attachments thereto trap the weight 10 between the diving tank
20 and the primary stage regulator 28. Thus, the weight 10 cannot
be inadvertently detached. Upon diving, the diver will fill his
buoyancy compensator device 26 with an appropriate amount of air to
maintain a proper horizontal trim and position.
[0028] In the present invention, a weight preferably of three
pounds will typically adequately control trim and position for
SCUBA divers in most situations with varying: tank type, size and
weight; diver weight and size; buoyancy compensating devices;
weight belts and other diver related equipment. However, a weight
of smaller or greater mass may be used up to a mass which is
appropriate for the given application and equipment. A weight of
two to four pounds would typically be adequate. Although lead is
the most feasible material to use for the weight, it can be made of
any suitable material.
[0029] In addition, the weight 10 would preferably be coated with a
protective frictional coating 18. This coating 18 could be rubber,
vinyl, plastic or the like. The coating 18 on the weight 10 would
protect the weight from corrosion, dampen any vibration of movement
of the weight 10 on the diving tank 20, resist sliding during the
dive, and further promote proper nesting of the weight 10 on the
diving tank 20 due to its frictional nature.
[0030] While the invention has been shown and described in some
detail with reference to specific exemplary embodiments, there is
no intention that the invention be limited to such detail. On the
contrary, the invention is intended to include any alternative or
equivalent embodiments that fall within the spirit and scope of the
invention as described herein.
