Description
TECHNICAL FIELD
The present invention relates generally to a door handle, and relates more particularly to a fluid-filled, aerated door handle for use with a cooler.
BACKGROUND OF THE INVENTION
Sculpted door handles have been placed on coolers and refrigerators used to house beverages or other items in retail outlets and elsewhere. These sculpted handles add to the aesthetics of the cooler door. The sculpted handles also may increase the exposure of the beverages or other items offered for sale to the passing consumers, i.e., the handle may catch the consumer's eye. For example, it is known to replace a cooler door handle with a handle sculpted in the shape of the well-known contoured bottle of The Coca-Cola Company of Atlanta, Ga. The use of such a sculpted handle serves to draw attention to the cooler and the beverages or other products within the cooler.
One goal in the design of the sculpted handles is to make the handle appear as close as possible to the product it is simulating. In the case of the contoured bottle, the design goal would be to have the handle appear as close as possible to an actual bottle of a carbonated soft drink. To date, this has been accomplished with a metal or a composite door handle manufactured in the shape of the contoured bottle. The handle is then painted partially with a dark color to simulate the carbonated beverage and partially with a light color to simulate the top of the bottle. The trademarks or other types of source indicia of the manufacturer or the distributor are then added to the door handle. Although the handle may appear to be an actual bottle at a distance, a close inspection of the handle may reveal that the handle is a close simulation.
What is needed, therefore, is a door handle or a similar object that attracts the eye of a consumer and also simulates a product to the greatest extent possible. Such a simulation should be realistic and easy to operate, while being relatively inexpensive to provide.
SUMMARY OF THE INVENTION
The present invention thus provides a bubbling door handle system for a cooler. The door handle system includes a door handle fixedly attached to the cooler. The door handle has a substantially transparent exterior surrounding an internal chamber. A fluid is positioned within the chamber. An air pump is positioned about the cooler. The air pump is in communication with the chamber so as to introduce air into the fluid. The result is the simulation of an actual beverage positioned within the chamber of the door handle.
Specific embodiments of the present invention include the use of a door handle having a bottle shape. The door handle may be made from a thermoplastic material. The fluid may be an oil solution such as an iso-paraffin oil. The fluid may have coloring therein. An aerator may be positioned within the chamber in communication with the pump so as to provide air bubbles to the fluid. The pump may be diaphragm pump. The pump may have a flow rate of about two liters per minute. The door handle may be fixedly attached to the cooler by a number of mounts or by similar means.
The door handle system may further include a number of air passageways connecting the pump and the chamber. The fluid may partially fill the chamber such that the chamber includes a fluid portion and an air portion. One of the air passageways connects the fluid portion of the chamber and one of the air passageways connects the air portion of the chamber. The air passageways may form an open loop system or a closed loop system with the pump.
A further embodiment of the present invention provides for a cooler with a number of beverages positioned therein. The cooler includes a door with a door handle fixedly attached thereto for movement therewith. The door handle may be made from a substantially transparent material. The door handle may have an internal chamber with a fluid positioned therein. The cooler also may include an air pump. The air pump may be in communication with the fluid in the chamber so as to provide the fluid with the appearance of one of the beverages position within the cooler. The door handle may have a bottle shape. The fluid may have the appearance of a carbonated soft drink or a similar beverage.
A further embodiment of the present invention provides for a bubbling door handle. The door handle may have a semi-transparent chamber for holding liquids and a compressor for the circulation of gas. A liquid may partially fill the chamber. An aerator may be positioned inside the chamber in communication with the compressor so as to release bubbles into the liquid. The door handle also has an intake tube for carrying gas from the compressor to the aerator and a vent for the release of gas from the chamber. The vent may be situated so as to avoid contact with the liquid.
Other objects, features, and advantages of the present invention will become apparent upon review of the following detailed description of the preferred embodiments of the present invention when taken in conjunction with the drawings and the appended claims.

DETAILED DESCRIPTION OF THE INVENTION
Referring now in more detail to the drawings, in which like numerals refer to like parts throughout the several views,
FIGS. 1-5
show a door handle system
100
of the present invention. The door handle system
100
preferably may be used with a refrigerator or a cooler
110
having a door
120
. The cooler
110
may be largely of conventional design. The cooler door
120
may swing open, slide open, or open in any convenient fashion. The cooler door
120
may be transparent in whole or in part. The cooler
110
preferably has a number of products
125
placed therein that are offered for sale. The products
125
may be carbonated soft drinks or any kind of refrigerated beverages, foods, or other items.
This invention is preferably implemented as a bottleshaped refrigerator door handle
130
. The shape of the door handle
130
will typically mirror the shape of the beverage bottles or other products
125
housed within the cooler
110
. The door handle
130
, however, may take any convenient shape. The door handle
130
may be made out of a transparent or semi-transparent thermoplastic material or any similar types of transparent or semi-transparent materials. The door handle
130
may be made by injection molding or other conventional types of manufacturing techniques. The door handle
130
may be e made from two halves that are welded together or otherwise fixedly joined.
The door handle
130
may be largely hollow with an interior chamber
140
. A fluid
150
may partially fill the chamber
140
. The fluid
150
fills a fluid portion
160
of the chamber
140
so as to leave an air portion
170
of the chamber
140
. The fluid
150
may be a colored oil solution, such as an isoparaffin oil. Water or any other type of liquid also may be used. The fluid
150
may have an anti-fungal agent added thereto. The fluid
150
may be colored so as to match the color of the beverage desired to be simulated. For example, a dark brown color may be used to simulate a typical cola beverage. Other colors may be used to simulate, for example, noncarbonated beverages, beer, milk, or other types of fluids. A foaming agent also may be added as needed.
The door handle
130
also may have an aerator
180
positioned within the chamber
140
. The aerator
180
may be largely of conventional design. The aerator
180
releases air into the fluid
150
as is known to those skilled in the art. The aerator
180
is a “sprinkler” or a “bubbler” device similar to an aquarium air “stone”. Specifically, the aerator
180
releases air bubbles
190
that rise to the top and break at the surface of the fluid
150
so as to simulate a carbonated soft drink or other type of beverage. The aerator
180
may be made out of a sintered phosphor bronze or similar materials. The aerator
180
also may include sintered glass beads or similar materials.
The door handle
130
also may include a bottle inlet
200
and a bottle outlet
210
. The bottle inlet
200
may be positioned in communication with the fluid portion
160
of the chamber
140
while the bottle outlet
210
may be positioned in communication with the air portion
170
of the chamber
140
. The aerator
180
may be in communication with the bottle linlet
200
via a bottle line
220
. The bottle line
220
may be any type of substantially air impermeable tubing.
The door handle
130
may be fixedly attached to the cooler door
120
by one or more mounts
230
. These mounts
230
may be separate elements that are fixedly attached to the door handle
130
or the mounts
230
and the door handle
130
may be an integral element. The mounts
230
also may be made from a thermoplastic material in an injection molding process or by any other type of conventional materials and methods. In
FIG. 2
, two mounts
230
are shown, a first mount
240
and a second mount
250
. Any number of mounts
230
, however, may be used. The mounts
230
may each have an air passageway
260
therein in communication with the chamber
140
of the door handle
130
. Specifically, the first mount
240
may have a first passageway
270
therein in communication with the chamber
140
via the bottle inlet
200
and the second mount
250
may have a second passageway
280
therein in communication with the chamber
140
via the bottle outlet
210
.
As is shown in
FIGS. 3 and 4
, the door handle system
100
may include a pump
300
in communication with the door handle
130
. The pump
300
may be a conventional diaphragm pump or any other type of air compressor. The pump
300
may be similar to a conventional aquarium air pump. The pump
300
may have a flow rate of about two liters per minute, although great variations in the flow rate may be accommodated. The operating pressure of the pump
300
may be about three to four psi (about 0.21 Kgf/cm
2
to about 0.28 Kgf/cm
2
), also with great variations therein to be accommodated. The pump
300
generally includes an exit vent
310
and an entrance vent
320
. A preferred air pump
300
is manufactured by Tetra/Second Nature, Inc. of the United States and sold under the name “Whisper 300” or by Yagami, Inc. of Japan and sold under the name “SP290”. The pump
300
may be positioned within or adjacent to the cooler
110
or in any other convenient location. The pump
300
may be operated by a conventional electrical source. The pump
300
may need to be modified to accept an air return line in addition to an air discharge line.
The pump
300
may be in communication with the door handle
130
via one or more conduits
330
. In this example, a first conduit
340
and a second conduit
350
are used. The conduits
330
may extend through the cooler
110
and the door
120
. The conduits
330
may extend adjacent to the hinge mechanism
335
of the door
120
. The conduits
330
may be any type of conventional, substantially air impermeable tubing. The first conduit
340
has a first air inlet
360
and a first air outlet
370
. The second conduit
350
has a second air inlet
380
and a second air outlet
390
. The first air inlet
360
of the first conduit
340
and the second air outlet
390
of the second conduit
350
are positioned near the pump
300
while the first air outlet
370
of the first conduit
340
and the second air inlet
380
of the second conduit
350
are positioned near the door handle
130
.
The present invention may be implemented as a closed loop system, in which the air is recirculated, or as an openloop system. In a closed loop system, air is delivered from the exit vent
310
of the pump
300
(
FIG. 4
) to the first air inlet
360
of the first conduit
340
. The first conduit
340
may extend through the door
120
of the cooler
100
to the first air outlet
370
. The first air outlet
370
is in communication with the first passageway
270
of the first mount
240
. The first passageway
270
is in communication with the aerator
180
of the door handle
130
via the bottle inlet
200
and the bottle line
220
. The air is then released into the fluid
150
via the aerator
180
. The air bubbles
190
then rise through the fluid
150
to the air portion
170
of the chamber
140
.
After rising through the fluid
150
and into the air portion
170
of the chamber
140
, the air is forced out of the chamber
140
via the bottle outlet
210
back towards the pump
300
. The bottle outlet
210
is in communication with the second passageway
280
within the second mount
250
. The second passageway
280
is in communication with the second conduit
350
positioned within the door
120
of the cooler
110
via the second air inlet
380
. The air travels through the second conduit
350
and exits via the second air outlet
390
. The second air outlet
390
is in communication with the entrance vent
320
of the pump
300
. The air is then forced through the pump
300
so as to repeat the cycle. This closed loop design minimizing fluid loss due to, for example, foaming or evaporation.
As an alternative, an open loop pump system also may be used. Specifically, the entrance vent
320
of the pump
300
may be accessible to the atmosphere. Likewise, the second conduit
350
also may be vented to the atmosphere. In fact, the outgoing air may vent anywhere down stream of the door handle
130
. Preferably, the second conduit
350
is vented at a location above the door handle
130
. The air also may be vented directly through the air portion
170
of the door handle
130
.
The door handle system
100
of the present invention thus provides a door handle that closely simulates an actual bottle with a carbonated beverage therein. Specifically, the door handle
130
is largely transparent and filled with the colored fluid
150
. The fluid
150
has the appearance of being an actual carbonated beverage because of the air bubbles
190
rising therein. The combination of the fluid
150
and the bubbles
190
serves to catch the eye of the consumer and encourages the purchase of an actual carbonated beverage or other product offered for sale within the cooler
110
.
It should be apparent that the foregoing description relates only to the preferred embodiments of the present invention and that numerous changes can be made herein without departing from the spirit and scope of the invention as defined by the following claims. Specifically, the scope of the present invention is defined by the following claims rather than the foregoing description.
