## Title
Double kick adapter for video game drum machine

## Abstract

An electronic apparatus that allows for the connection of a pair of bass drum pedals to a single controller further comprises an electronic circuit housed within an enclosure and provided with two (2) input jacks to allow connection of two (2) standard bass drum pedals from the drum controller used in the video game ROCK BAND® (video game). An output cable is then provided for connection to the drum controller. The electronic circuit accepts the switch closure connections from either pedal and uses an array of electronic components to drive a relay which produces a contact closure. This contact closure is then used to feed the controller. The electronic circuit eliminates the collision and cancellation effects associated with simply combining the pedal closures in parallel. In such a manner, a videogame player can generate a greater number of bass drum pedal actuations in a given period of time by using both feet.

## Background
RELATED APPLICATIONS
The present invention was first described in and claims the benefit of U.S. Provisional Application No. 61/263,963 filed Nov. 24, 2009, the entire disclosures of which are incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates generally to music video games, and in particular, to an electronic double bass drum pedal adapter for music video games.
BACKGROUND OF THE INVENTION
Home video game systems are more popular than ever. Modern technological advancements in gaming systems have resulted in literally hundreds of games with unprecedented depth and detail. It is in the not-too-distant future that one could envision the home video game system as a standard item in almost every American home in much the same manner as a television or computer is.
As these numbers continue to increase, the market for gaming accessories is growing as well. An example of a recent game which is very popular is the game ROCK BAND® (video game). It uses various controllers to mimic various instruments in a rock band. The drum controller used with this game even has a bass drum foot pedal.
One (1) problem associated with such games is that the bass drum foot pedal controller can only be actuated using a single foot. Many users have attempted to plug multiple pedals into one (1) controller, but due to the configuration of these controllers the signals from one (1) pedal will block out and overlap the signals from the other pedal.
Various attempts have been made to provide music video game controllers. Examples of these attempts can be seen by reference to several U.S. patents. U.S. Pat. No. 6,835,887, issued in the name of Devecka, describes a method and apparatus for providing an interactive musical game including a plurality of electronic drum pads and displays which simulate a live drum setup.
U.S. Pat. No. 7,320,643, issued in the name of Brosius et al., describes a game controller simulating a guitar.
U.S. Pat. No. 7,351,148, issued in the name of Rothschild et al., describes an electronic sequence matching game including a controller with which a user must match timed sequences produced by the game.
While these apparatuses fulfill their respective, particular objectives, each of these references suffer from one (1) or more of the aforementioned disadvantages. Many such apparatuses are not adapted for use with existing music video game controllers. Furthermore, many such apparatuses are unsuited for mimicking a traditional double kick drum pedal assembly commonly found on analog drum sets. Accordingly, there exists a need for a double kick adapter without the disadvantages as described above. The development of the present invention substantially departs from the conventional solutions and in doing so fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing references, the inventor recognized the aforementioned inherent problems and observed that there is a need for an apparatus adapted for use with an existing music video game system which allows a user to emulate a double kick drum pedal assembly. Thus, the object of the present invention is to solve the aforementioned disadvantages and provide for this need.
To achieve the above objectives, it is an object of the present invention to provide an adapter for the connection of a pair of foot pedals to a single drum controller for a music video game. The apparatus accepts a connection cable from each foot pedal and the drum controller accepts output cable from the apparatus to enable a user to utilize each foot pedal while playing the video game.
Another object of the present invention is to house the electrical and electronic components of the apparatus in a protective enclosure.
Yet still another object of the present invention is to comprise a primary embodiment which allows for adaptation to an existing drum controller.
Yet still another object of the present invention is to comprise an alternate embodiment built into a drum controller as a part of an original equipment manufacturing configuration.
Yet still another object of the present invention is to provide continuous power to the apparatus via connection to a 120-VAC power outlet using a power cord.
Yet still another object of the present invention is to comprise a first signal jack and a second signal jack disposed along an exterior surface of the enclosure which receive a foot pedal output cable from the foot pedals.
Yet still another object of the present invention is to allow simultaneous operation of both foot pedals by producing an instantaneous switch closure at the instant of either switch closure from the foot pedals. This allows the apparatus to emulate the functionality of an analog double bass drum pedal assembly while playing the music video game.
Yet still another object of the present invention is to conserve energy consumption by comprising a battery and a battery power switch which allow the user to selectively operate the apparatus without connection to the power outlet.
Yet still another object of the present invention is to comprise internal circuitry which relays electrical signals from the foot pedals to the drum controller.
Yet still another object of the present invention is to provide a method of utilizing the device that provides a unique means of obtaining an instance of the apparatus, activating the apparatus by plugging in the power cord or operating the apparatus with the internal battery, plugging up to two (2) foot pedals into a respective jack, plugging the output cable into the drum controller, utilizing either foot pedal to perform an action which pertains to the game being played, and simulating a double bass drum pedal assembly.
Further objects and advantages of the present invention will become apparent from a consideration of the drawings and ensuing description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within FIGS. 1 through 5. However, the invention is not limited to the described embodiment and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention, and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items.
The present invention describes a dual pedal for interface for a video game system (herein described as the “apparatus”) 10, which provides an adapter for the connection of a pair of bass drum pedals 25 to a single drum controller 20 in a video game such as ROCK BAND® (video game). The apparatus 10 accepts connection cable 27 from each drum pedal 25 and the drum controller 20 accepts output cable (P3) 55 from said apparatus 10 to enable a player to utilize each said pedal 25 during playing of the video game.
Referring now to FIG. 1, an isometric view of the apparatus 10, according to the preferred embodiment of the present invention, is disclosed. The functional components of the apparatus 10 are provided within an enclosure 15. The overall size of the enclosure 15 is approximately one-and one-half (11⁄2) inches tall, four (4) inches wide and one-and-one-half (11⁄2) inches deep. The enclosure 15 houses the necessary discrete components and associated circuitry to provide the necessary functionality to the apparatus 10. While the present invention depicts the enclosure 15 as a separate device to allow for adaptation to an existing drum controller 20, future versions of the present invention could be built into either the drum controller 20 or one (1) of the two (2) foot pedals 25 as part of an original equipment manufacturing configuration. As such, the enclosure 15 should not be interpreted as a limiting factor of the present invention. A power cord (P1) 30 is used to connect the apparatus 10 to a suitable source of electric power as provided through a 120 VAC power outlet 35 via a disconnect plug (P2) 40. The foot pedals 25 are connected into a first signal jack (J1) 45 and a second signal jack (J2) 50 respectively on the enclosure 15 via their existing foot pedal output cables 27 while an output cable (P3) 55 is used to connect the output signal from the apparatus 10 to the drum controller 20. The apparatus 10 produces an instantaneous switch closure at the instant of either switch closure from the foot pedals 25. The closure immediately opens back up again regardless of whether or not the foot pedals 25 was released. In such a manner the other foot pedal 25 can immediately issue a closure command without waiting for the prior engaged foot pedal 25 to be released. Such a feature eliminates the collision and cancellation effects associated with simply combining the pedal closures in parallel. Thus, a player can generate a greater number of bass drum pedal actuations in a given period of time by using both feet. Additionally, such features add to the excitement of the game and allow for higher scores.
Referring next to FIG. 2, an end view of the apparatus 10, according to the preferred embodiment of the present invention is depicted. This view more clearly shows the power cord (P1) 30 connected to the enclosure 15 via the disconnect plug (P2) 40. The 120 VAC power outlet 35 allows for the continuous operation of the apparatus 10 without usage of internal battery (B1) 57 (see FIG. 4) thus allowing basically unlimited operational time. Since the operation of the gaming system associated with the drum controller 20 requires the presence of conventional AC electrical power as provided by the 120 VAC power outlet 35, the operation of the apparatus 10 is aligned in the same manner. The internal battery (B1) 57 is disconnected from the circuit via a top mounted battery power switch (S1) 60. Thus for operation via a 120 VAC power outlet 35 (as seen in FIG. 1), the battery power switch (S1) 60 is left in an off state and the operation of the apparatus 10 is controlled by simply plugging the power cord (P1) 30 in and out of the 120 VAC power outlet 35. It can be left plugged in at all times due to the low power consumption of the apparatus 10. To operate the apparatus 10 on its internal battery (B1), the apparatus 10 is left unplugged from the 120 VAC power outlet 35, and the battery power switch (S1) 60 turned on. It is turned off when utilization of the apparatus 10 is complete to conserve battery power.
Referring now, to FIG. 3, an opposite end view of the apparatus 10, according to the preferred embodiment of the present invention is shown. This figure more clearly depicts the first signal jack (J1) 45 and the second signal jack (J2) 50 located on the face of the enclosure 15 along with the output cable (P3) 55 leaving the enclosure 15. The first signal jack (J1) 45 and the second signal jack (J2) 50 are comprised of a standard eighth-inch (1⁄8) mono plug design such that it can connect to standard foot pedals 25 and standard drum controller 20 without customization. The battery power switch (S1) 60 is also visible on the top of the enclosure 15. Also visible is a light-emitting diode (LED) (D4) 65 to indicate operation of the apparatus 10 and help alert the player to turn off said apparatus 10 when utilization is no longer needed.
Referring next to FIG. 4, an electrical schematic diagram of the apparatus 10, according to the preferred embodiment of the present invention is disclosed. Electrical power is introduced to the apparatus 10 via the power cord (P1) 30 and the disconnect plug (P2) 40 as shown into a transformer (T1) 70. The resultant AC power is converted to DC by a first integrated circuit (U1) 75. Further regulation and filtering of the power is provided by a second integrated circuit (U2) 80 and a first transistor (Q1) 85. This resultant power is then sent to a third integrated circuit (U3) 90 which is also supplied power via the internal battery (B1) 57 through the battery power switch (S1) 60. The resultant power from the third integrated circuit (U3) 90 is then delivered to the light-emitting diode (LED) (D4) 65 to indicate operation as well as to a fourth integrated circuit (U4) 95. The first signal jack (J1) 45 and the second signal jack (J2) 50 provide trigger inputs to the fourth integrated circuit (U4) 95. Various values of related circuit components control the time duration and cycle times. The resultant output is then directed through a second transistor (Q2) 100 which drives the coil of a mechanical relay (K1) 105. The output contacts of the mechanical relay (K1) 105 are then directed through the output cable (P3) 55 which are used to trigger the drum controller 20 (as shown in FIG. 1). Said description is an overview of circuit operation. Other components not described serve related functions associated with the above description and will be readily discernable to those skilled in the art. Further description of all circuit components will be provided herein below.
Referring finally to FIG. 5, a chart depicting the parts list of the electronic components as used with the apparatus 10 is depicted. Said description can be related to circuit designations as provided in FIG. 4 with corresponding representation made to certain specific components in other figures. Exact part numbers and values serve to represent circuit operation and are not intended to limit or exclude other specific parts or values which may work equally as well.
It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
The preferred embodiment of the present invention can be utilized by the common player in a simple and effortless manner with little or no training. After initial purchase or acquisition of the apparatus 10, it would be installed as indicated in FIG. 1.
The method of installing and utilizing the apparatus 10 may be achieved by performing the following steps: acquiring the apparatus 10; activating the apparatus 10 via plugging in the power cord (P1) 30 into a 120 VAC power outlet 35 or operating the apparatus 10 with the internal battery (B1) 57 and depressing the battery power switch (S1) 60; plugging up to two (2) foot pedals 25 into a respective jack (J1, J2) 45, 50; plugging the output cable (P3) 55 into the drum controller 20; placing each foot upon a foot pedal 25; utilizing either foot pedal 25 to perform an action which pertains to the game being played; deactivating the apparatus 10 via disconnecting the power cord (P1) 30 from the 120 VAC power outlet 35 or depressing the battery power switch (S1) 60; and, utilizing the apparatus 10 as desired.
