The present invention relates to systems and methods for providing electrical power to a tap assembly on a beverage dispenser.
Bar taps are well known, and are traditionally used in conjunction with a beverage dispenser to control the release of the beverage. Normally, the beverage dispenser will have one or more tap stems, to which a decorative tap handle may be attached. Decorative tap handles are designed and used to let customers know that a certain beverage is available and to entice them to try that beverage.
Specifically and in one non-limiting example, beer breweries create tap handles of all shapes and sizes to brand their product, to lure new customers to try their beer and/or to let existing customers know which of their particular beverages are available at a given establishment. Indeed, decorative beer tap handles are often the primary marketing vehicle for some smaller scale breweries, such as micro and craft breweries. These breweries often rely on the eye-catching ability of their decorative tap handle to generate business and enlarge their customer base.
However, traditional decorative tap handles, which are commonly made of plastic or wood, have certain limitations. Specifically, and as currently used, these traditional handles are not provided with electrical power. By lacking electrical power, the traditional tap handles can only be effective marketing tools if the potential customer is already looking at the tap, as the non-powered handles are unable to draw attention in the way that an electrically-powered lighted, sound producing or moving tap handle could.
The benefits of providing powered tap handles and a method for achieving the same has been previously addressed in U.S. Pat. No. 6,932,638 (the '638 patent), which is co-owned and fully incorporated by reference herein. While the design described in the '638 patent provided a number of important advances, certain drawbacks that made the mounting and use of the described beer tap assemblies more difficult than necessary in some circumstances remained. For example, in the systems described in the '638 patent, an insulated conductive wire entered the assembly through a hole in a bushing that rotated freely around the locknut. The wire then traveled between the bushing and the locknut. This configuration generated a number of unanticipated drawbacks. For example, the orientation of the wire, when it exited the hole in the bushing, could not be controlled. This lack of control had the dual results of limiting the possible configurations of the tap assembly and being aesthetically unpleasing (potentially resulting in the loss of advertising effectiveness). Further, the wire was unprotected as it entered the hole, which often resulted in fraying or breakage. In addition, the wire would get pinched between the bushing and the locknut, which also resulted in frequent fraying and breakage. Moreover, the hole in the bushing allowed particles to enter into the cavity between the bushing and the locknut, which often resulted in the bushing losing its rotational independence, as well as adding yet another source of wear on the wire. As a final example of drawbacks associated with the systems described in the '638 patent, these systems failed to provide for a reliable mechanism for attaching the bushing to the locknut. This lack of reliable attachment resulted in the bushing frequently falling off of the locknut, thus crippling both the effectiveness and aesthetic appeal of the '638 system. The '638 system also left room for improvement in the attachment of tap handles to the tap assembly. Thus, despite the advancements provided by the '638 patent, there is still significant room for improvement in providing powered tap assemblies.
The present invention addresses drawbacks associated with prior powered tap assembly designs by providing systems and methods that allow for independent rotation of a particular tap assembly's conductive wire entry point as compared to the rest of the tap assembly while also allowing for the control of the wire's final orientation and protection of the wire at its entry point into the tap assembly and while also providing a design that maintains the integrity of the powered tap assembly by preventing dirt or other debris from entering relevant portions of the assembly through the wire's entry point. The present invention provides this benefit by providing a slip ring with a conductive wire entry point between each tap assembly's locknut and ferrule assembly. The slip rings according to the present invention can rotate independently as compared to the other components of the tap assembly. Further, the slip rings provide a novel way for electrical power to enter into a tap handle. Specifically, the slip ring acts to control the direction of the wire as it enters into the tap assembly. Further, the slip ring design advantageously provides a connection which is protected and subjected to much less fraying and breakage than previously designed powered tap handle systems. The slip ring also provides a reliable mechanism for maintaining rotational independence that is less likely to break down with consistent use. In addition, the ferule assembly of the present invention provides a reliable mechanism for attaching a tap handle to a powered tap assembly. The present invention also provides for a tap assembly that is sleeker and more attractive than previous systems, which is important given the use of tap handles for advertising.
Specifically, one embodiment according to the present invention comprises a tap assembly comprising a locknut; a slip ring; and a ferrule assembly; wherein the slip ring is positioned between the locknut and the ferrule assembly; wherein the rotational position of the slip ring can be adjusted relative to the rotational positions of the locknut and/or the ferrule assembly; and wherein the slip ring can accept conductive wires into the tap assembly so that the wires can provide power to the tap assembly.
In another embodiment according to the present invention, the slip ring comprises one or more conductive elements. In certain embodiments, the conductive elements can be conductive rings. Slip rings according to the present invention can also comprise an overmold.
Ferrule assemblies used in accordance with the present invention can comprise a circuit board, a ferrule base, a ferrule wire, and a ferrule stud. Locknuts can comprise a vertical indentation to restrict vertical movement of the slip ring.
One embodiment according to the present invention comprises a powered tap handle system comprising a tap assembly and a power supply system wherein the tap assembly comprises a locknut; a slip ring; and a ferrule assembly, wherein the slip ring is positioned between the locknut and the ferrule assembly; and wherein the rotational position of the slip ring can be adjusted relative to the rotational positions of the locknut and/or the ferrule assembly; and wherein the power supply system comprises a non-conductive protective layer comprising a top surface and a bottom surface; a non-conductive support layer comprising a top surface and a bottom surface; a first conductive material; and a second conductive material, wherein the first conductive material and the second conductive material are located between the top surface of the protective layer and the bottom surface of the support layer and wherein the non-conductive support layer is shaped to allow access to the first conductive material and the second conductive material by a first conductive contact associated with a first conductive wire and a second conductive contact associated with a second conductive wire, wherein when engaged to the first and second conductive materials the first and second conductive contacts and associated conductive wires carry power to the tap assembly via an entry point in the slip ring.
In another embodiment of a powered tap handle system according to the present invention, the slip ring comprises one or more conductive elements and the ferrule assembly comprises a circuit board, a ferrule base, a ferrule wire, and a ferrule stud.
The present invention also includes a ferrule assembly for use with a tap assembly wherein the tap assembly comprises a locknut and a slip ring comprising one or more conductive elements; wherein the slip ring is positioned between the locknut and the ferrule assembly; and wherein the slip ring can accept conductive wires into the tap assembly so that the wires can provide power to the tap assembly. In certain embodiments according to present invention, the ferrule assembly comprises a circuit board, a ferrule base, a ferrule wire, and a ferrule stud.
The present invention also includes a slip ring for use with a tap assembly wherein the tap assembly comprises a locknut and a ferrule assembly comprising a circuit board, a ferrule base, a ferrule wire, and a ferrule stud wherein the slip ring is positioned between the locknut and the ferrule assembly and wherein the rotational position of the slip ring can be adjusted relative to the rotational positions of the locknut and/or the ferrule assembly; and wherein the slip ring can accept conductive wires into the tap assembly so that the wires can provide power to the tap assembly.
Slip rings of the present invention can comprise one or more conductive elements. In certain embodiments, the conductive elements can be conductive rings. In further embodiments, the rotational position of the slip ring can be adjusted relative to the rotational positions of the locknut and/or the ferrule assembly. Slip rings can also comprise overmolds in certain embodiments and, when desired, can be sized to fit into a vertical indentation which is found on the locknut in certain specific embodiments.
The present invention also includes methods. One method according to the present invention includes a method for accepting power into a tap assembly comprising providing a locknut; providing a slip ring; and providing a ferrule assembly, wherein the slip ring is positioned between the locknut and the ferrule assembly; and wherein the slip ring accepts conductive wires into the tap assembly so that the wires can provide power to the tap assembly.
In another embodiment of the methods according to the present invention, the slip ring comprises one or more conductive elements. In another embodiment the rotational position of the slip ring can be adjusted relative to the rotational positions of the locknut and/or the ferrule assembly and the slip ring can further comprise an overmold.
In another embodiment of the methods according to the present invention the ferrule assembly comprises a circuit board, a ferrule base, a ferrule wire, and a ferrule stud.
The present invention also includes tap handles for use with the tap assemblies described herein. In one embodiment, the present invention includes a tap handle for use with a tap assembly wherein the tap assembly comprises a locknut; a slip ring; and a ferrule assembly comprising a circuit board, a ferrule base, a ferrule wire, and a ferrule stud, wherein the slip ring is positioned between the locknut and the ferrule assembly; wherein the rotational position of the slip ring can be adjusted relative to the rotational positions of the locknut and/or the ferrule assembly; wherein the slip ring can accept conductive wires into the tap assembly so that the wires can provide power to the tap assembly and wherein the tap handle is attached to the ferrule stud. In another embodiment, the slip ring comprises one or more conductive elements. In another embodiment of the tap handles according to the present invention, the tap handle performs a function selected from the group consisting of lighting, producing sound, moving, vibrating, and combinations thereof.
Existing tap handles as they are presently used in commercial establishments fail to capitalize on their full advertising potential by failing to effectively draw attention to the beverage with which they are associated. While this drawback was addressed in U.S. Pat. No. 6,932,638 (the '638 patent), which is fully incorporated by reference herein, the systems and methods described in the '638 patent had certain design features that could make their mounting and use more difficult than necessary in some circumstances. For example, due to a problematic wire entry position, those systems and methods had limited configurations. The previous mechanism for wire entry also often resulted in the wire fraying and breakage, thus crippling the functionality of the systems. Further, the '638 system was problematic in that it could not maintain the rotational independence of the wire entry point over a sustained period of time. The present invention addresses these drawbacks of previous approaches and provides a system for transferring electrical power to tap handles so that the handles can move, produce sound, light up, etc. in order to draw the eye of potential customers. Further, the systems and methods of the present invention also provide an advance in the ease and effectiveness with which powered tap assemblies can be mounted and used. The systems and methods according to the present invention address the drawbacks of previously used systems in part by providing for a slip ring in the tap assembly design that provides for independent movement of the wire entry point. This advance also facilitates mounting the tap assemblies in various configurations, and prevents the wires from undue incidences of fraying and/or breakage. The slip ring system also provides a more robust and protective mechanism while maintaining the rotational independence of the wire entry point.

In other specific embodiments, the conductive wires may be directly crimped, soldered, or otherwise connected to each conductive ring 301, 303. In yet other specific embodiments, the conductive wires may be crimped, soldered, or otherwise connected to two conductive spring connectors, brushes, or other connectors adapted to provide continuous contact with one of conductive rings 301, 303.
In specific embodiments, electrical power may be transferred to slip ring 103. In one such embodiment, a powered lead may be connected to upper conductive ring 301 and a neutral lead may be connected to lower conductive ring 303. In one specific embodiment, the powered lead may have, without limitation, about 6 volts on it and the neutral lead may have about 0 volts on it. As will be understood by one of ordinary skill in the art, however, depending on the intended use for a particular electrical power supply system, various other voltages can be used in accordance with the systems and methods of the present invention.
In a specific embodiment shown in
As shown in
Circuit board 501 comprises an electrical contact which, in certain embodiments, engages upper conductive ring 301 although it is understood that various other connection configurations are achievable in accordance with the present invention. In the described embodiments, circuit board 501 is connected to ferrule wire 504, and acts to provide an electrical connection between the upper conductive ring 301 and ferrule wire 504. The connection between circuit board 501 and ferrule wire 504 may be made by soldering, clamping, or any other method of attachment as understood by one of ordinary skill in the art. In a specific embodiment, circuit board 501 may be a printed circuit board. In another embodiment, circuit board 501 may simply comprise a conductive ring similar to those in slip ring 103. In some embodiments, circuit board 501 further comprises an insulating layer that keeps ferrule base 502 from coming in contact with upper conductive ring 301, as well as with any metal portion that contacts upper conductive ring 301. Further, in specific embodiments, the connection between circuit board 501 and ferrule wire 504 is similarly insulated. This insulation is important to prevent shorts, as ferrule base 502 and ferrule stud 504 act as a neutral ground in certain embodiments, while upper conductive ring 301 and ferrule wire 504 act as powered leads.
Ferrule wire 504 serves as a conduit for electrical power to travel from circuit board 501 to tap handle 650 (
As discussed above, electrical power may be transferred to slip ring 103, in the manner of a powered lead connected to upper conductive ring 301 and a neutral lead connected to lower conductive ring 303. Also as discussed above, circuit board 501 acts to provide an electrical connection between the upper conductive ring 301 and ferrule wire 504. As such, if a powered lead is connected to upper conductive ring 301, ferrule wire 504 is also a powered lead. In such a situation, a neutral lead would be connected to lower conductive ring 303. Lower conductive ring 303 is designed to contact locknut 102, which is designed to contact tap stem 101 and ferrule base 502, which in turn contacts ferrule stud 503. As each of these components is conductive, they each act as a neutral lead when a neutral lead is connected to lower conductive ring 303.
Of course, in certain embodiments, lower conductive ring 303 may be connected to a powered lead, while upper conductive ring 301 may be connected to the neutral ground. In such an embodiment, the above conductive paths could still hold true, but be updated to powered instead of neutral and vice-versa. Alternatively, the invention may be adapted such that ferrule wire 504 is configured to make electrical contact, via circuit board 501, locknut 102, or ferrule base 502, with lower conductive ring 303.
In a further alternative embodiment, ferrule wire 504 may comprise a wire with two conductive materials which are insulated from each other. In such an embodiment, circuit board 501, locknut 102, and slip ring 103 are configured such that each of the two conductive materials in ferrule wire 504 contacts one of conductive rings 301, 303 and thus act as the powered and neutral lead for tap stem 101.
Tap assemblies of the present invention can be used with a variety of power systems, one of which is described herein. This power system is also described in copending U.S. application Ser. No. ______ which is fully incorporated herein by reference.
In certain embodiments, first conductive material 20 may act as a powered lead and second conductive material 30 may act as a neutral lead. Alternatively, first conductive material 20 may act as a neutral lead and second conductive material 30 may act as a powered lead. In either embodiment, the powered lead may have, without limitation, below about 6 volts on it and the neutral lead may have about 0 volts on it. As will be understood by one of ordinary skill in the art, however, depending on the intended use for a particular electrical power supply system, various other voltages can be used in accordance with the systems and methods of the present invention.
In addition to a first and second conductive material 20, 30, the described power system also comprises a protective layer 100. As shown, protective layer 100 may comprise a top surface 110 and a bottom surface 120. Protective layer 100 may comprise any non-conductive material as understood by one of ordinary skill in the art, and may specifically comprise, without limitation, rubber, polyethylene, polyvinyl chloride, impregnated paper, neoprene, plastic, foam, glass, porcelain, composite, or any combination thereof. Protective layer 100 may comprise, without limitation, a flexible, semi-flexible, rigid or semi-rigid material. As shown in
In certain embodiments of these exemplary power supplies used in accordance with the present invention, protective layer 100 acts as a barrier to prevent access to first and second conductive material 20, 30 from one side (in one embodiment the top side) of electrical power supply system 50. In specific embodiments, protective layer 100 may also act to keep first conductive material 20 from coming into contact with second conductive material 30. In other specific embodiments, protective layer 100, first conductive material 20, and second conductive material 30 may be created together as a co-extrusion. Because protective layer 100, in specific embodiments, acts as a barrier between the conductive materials 20, 30 and accidental contact and/or liquid spills, it also blocks access to conductive materials 20, 30 that is necessary to utilize the electrical power supply system 50. As such, a novel way to connect to the conductive materials 20, 30 is needed, and is provided for below.
In addition to first and second conductive material 20, 30 and protective layer 100, the described exemplary power system that can be used with the tap assemblies of the present invention also comprises a support layer 40. As shown in
Support layer 40 may comprise any non-conductive material as understood by one of ordinary skill in the art, and may specifically comprise, without limitation, rubber, polyethylene, polyvinyl chloride, impregnated paper, neoprene, plastic, foam, glass, porcelain, composite, or any combination thereof. In specific embodiments, support layer 40 may comprise a flexible, semi-flexible, rigid or semi-rigid material. In specific embodiments, support layer 40 may be about one quarter inch thick, although this dimension is not required and is provided for exemplary purposes only. Thus, this described power system provides an electrical power supply system that can be used in highly trafficked areas without the risk of inadvertent shock, shorts due to liquid spills or other contact and provides a beneficial power system to be used with tap assemblies of the present invention.
In certain embodiments of the exemplary power systems described herein, the bottom surface 420 of support layer 40 may comprise an adhesive surface. Alternatively, bottom surface 420 of support layer 40 may be otherwise associated with an adhesive (through, without limitation, fastening to an adhesive film, coating with an adhesive substance, etc.). In those specific embodiments wherein bottom surface 420 of support layer 40 is adhesive or otherwise associated with an adhesive, the adhesive may be used to mount electrical power supply system 50 upon various surfaces. Further, the adhesive may be of sufficient strength for permanent mounting, or it may be of a strength needed for temporary mounting.
As shown in
Each of third conductive material 710 and fourth conductive material 810 may comprise any conductive material as understood by one of ordinary skill in the art, and may specifically comprise any appropriate metal such as, without limitation, copper, silver, aluminum, steel, gold, tin, lead, nickel, or an alloy; any appropriate non-metallic conductor such as, without limitation, graphite; or any combination thereof. As shown, third conductive material 710 and fourth conductive material 810 may each comprise a round wire. Alternatively, third conductive material 710 and fourth conductive material 810 may each comprise a flat strip or any other appropriate shape. In specific embodiments, third conductive material 710 and fourth conductive material 810 may each comprise a flexible, semi-flexible, rigid or semi-rigid material.
As discussed above, in specific embodiments, first conductive material 20 may act as a powered lead and second conductive material 30 may act as a neutral lead. In such a situation, when first conductive contact 70 engages first conductive material 20, first conductive contact 70 and third conductive material 710 also become powered leads and second conductive contact 80 and fourth conductive material 810 become neutral leads. As such, electrical power can be routed through electrical power supply system 50 to a tap assembly of the present invention. Similarly, if first conductive material 20 was acting as a neutral lead and second conductive material 30 was acting as a powered lead, first conductive contact 70 and third conductive material 710 would become neutral leads and second conductive contact 80 and fourth conductive material 810 would become powered leads, thus also enabling electrical power to be routed through electrical power supply system 50 to a tap assembly of the present invention.
As will be understood by one of ordinary skill in the art, in specific embodiments, connector device 60 may comprise an over-current protection circuit. In such specific embodiments, the over-protection circuit may monitor the current voltage draw of the electrical device that it is associated with, and may terminate operation of that connector device 60 if that voltage draw exceeds a preset voltage level. In such embodiments, connector device 60 may have one or more indicators, such as, in one non-limiting example, one or more light emitting diodes (LEDs) attached to it to indicate the operation status of that connector device 60. For example, if the connector device 60 is working, a green LED may be lit, and if the connector device 60's operation has been terminated by the over-current protection circuit, a red LED may be lit. In alternative embodiments, some other notification device may be used to indicate when the over-current protection circuit has terminated operation of a connector device 60. In specific embodiments, the over-current protection circuit may be automatically resetting. For example, once a given connector device 60's operation has been terminated by an over-current protection circuit, in certain embodiments that connector device 60's operation can be restored by disconnecting it from electrical power supply system 50 and then reconnecting it. Alternatively, the system can reset by eliminating the source of fault by, without limitation, replacing faulty portions of the system. Mechanisms to achieve these benefits are understood by those of ordinary skill in the art.
In specific embodiments, connector device 60 may be used as a conduit to route electrical power from a power source to electrical power supply system 50. In such specific embodiments, the power source may be, without limitation, a standard low voltage transformer, a standard DC power supply, or any other power source as understood by one of ordinary skill in the art.
As will be understood by one of ordinary skill in the art, ferrule wire 504 carries power to tap handle 650 (
Although the present invention has been described in considerable detail with reference to certain specific embodiments, other embodiments and variations will be apparent to those of ordinary skill in the art.
