Description

Firearm Having Central Power Source and Integrated Data Bus to both Power and
Control Multiple Accessories Technical Field
The present disclosure provides a firearm having one or a plurality of rails for mounting weapon attachments (accessories), said rails having a central power source capable of powering the accessory devices that electrically connects through a series of parallel rails circumferentially surrounding a barrel or otherwise attached to a firearm. More specifically, the present disclosure provides a central power source that provides electric power to one or a plurality of rail accessories and that provides electric power to each rail-mounted accessory through one or a plurality of conducting strips located on each rail element. In addition, the present disclosure provides a method for transmitting information among and between rail- mounted weapon attachments using the rails as a data bus or as an antenna. Digital or analog signals can be transmitted and received by and between attachments mounted to the rails by means of the rails. Background
Various accessory devices are often used together with firearms, particularly, automatic or semiautomatic firearms. Such accessories often utilize electric power and generally need DC electric power in the 3 volt or 6 volt range and include, for example, flashlights, laser target designators, laser optical scopes and launchers of ordinance. Each such accessory typically comes with its own independent electric power source, often primary or secondary batteries. These batteries may or may not need changing or recharging during a specific mission.
Firearms, such as carbines of the "M" series or even AK47 type weapons, have a central barrel with the ability to integrate accessory mounting rails circumferentially surrounding the barrel and barrel housing element. Additional opportunities exist for placing rails on other places on the firearm. However, each accessory is independent and operates independently of others due to a lack of electrical communication by and between the accessories that are mounted to the one or a plurality of accessory-mounting rails. Therefore, there is a need to be able to centrally control and provide electric power to accessories rather than having to operate each accessory independently.
Therefore, there is a need in the field of firearms to be able to centralize the electric power needs of one or a plurality of accessories through a common "hot" rail system that transmits power to the accessories through its attachment to the firearm through a mounting rail. Various means of communication have been developed between trains using the train tracks to transmit radio frequencies (U.S. Patent 6,830,224, the disclosure of which is incorporated by reference herein). The conducting strips in the present invention can serve a similar purpose allowing accessories mounted to the rails to transmit and receive information by and between each accessory. However, many issues of significant distances and large masses of metal exist for railroads that do not exist in the much smaller environment of firearms and weapons systems carried by individuals. Therefore, there is a need in the art to coordinate the performance of, and transmit information between, multiple accessories in firearms and weapons systems. The present disclosure was made to also address this issue. Summary
The present disclosure provides a firearm having a one or a plurality of mounting fixtures, preferably circumferentially surrounding a barrel, wherein each mounting fixture comprises one or a plurality of common electric conductors, and wherein each common conductor is electrically connected to a power source, wherein the power source is AC or DC. Preferably, the common conductors comprise a copper or brass strip of metal in electrical contact with a power source. More preferably, the power source is a portable device that produces voltage or current power. More preferably, the power source is selected from the group consisting of a battery, a Lithium ion rechargeable battery, a fuel cell, a grid power transformed, and combinations thereof. Preferably, the power source is located on a mounting fixture as an accessory device, within an ammo clip, within the stock of the firearm or attached to another location surrounding the barrel of the firearm. Preferably, two or more common conductors are located on opposite sides of the mounting fixture or two or more common conductors are located on the same side of a mounting fixture. Preferably, the power source provides voltage or current that is either direct or alternating. More preferably, the power source provides voltage output from about 2 volts to about 12 volts. Preferably, the common conductors further carry RF (radio frequency) signals to communicate between the accessories. Preferably, the common conductors are a data transmission means that allow accessories in contact with the common conductors to transmit and/or receive analog and/or digital signals from and to other accessories in contact with the common conductors. Alternatively, the accessory mounting rail may incorporate a data transmission means that is separate from the common conductors that will allow accessories mounted to the rail to transmit and/or receive data from each other. Such a separate means may be, for example, a fiber optic bus, a two wire Ethernet bus, a serial communications bus and other means that will be evident to one skilled in the art. Alternatively, the data transmission means may incorporate both the common conductors and one or a plurality of separate data transmission means. The accessories may or may not need to be attached to the mounting fixtures as a source of power. Preferably, the common conductors are coated with a silicon lubricant so that the conductors will not short if the firearm is carried through water. The present disclosure further provides a firearm or weapons system having a plurality of fixtures, comprising
(a) one or a plurality of mounting fixtures circumferentially surrounding a barrel or otherwise attached to the body of a firearm or weapons system, wherein each mounting fixture comprises one or a plurality of common conductors, and wherein each common conductor is electrically connected to a power source; and
(b) a radio frequency (RF) antenna embedded within the plurality of common conductors, wherein each RF antenna is capable of transmitting or picking up radio frequency signals; or
(c) a data transmission means that allows accessories in contact with the data transmission means to transmit and/or receive data from other accessories in contact with the data transmission means.
Preferably, the common conductors comprise a copper or brass strip of metal in electrical contact with a power source. More preferably, the power source is a portable device that produces voltage or current power. More preferably, the power source is selected from the group consisting of a battery, a Lithium ion rechargeable battery, a fuel cell, a grid power transformed, and combinations thereof. Preferably, the power source is located on a mounting fixture as an accessory device, within an ammo clip, within the stock of the firearm or attached to another location surrounding the barrel of the firearm. Preferably, two or more common conductors are located on opposite sides of the mounting fixture or two or more common conductors are located on the same side of a mounting fixture. Preferably, the power source provides voltage or current that is either direct or alternating. More preferably, the power source provides voltage output from about 2 volts to about 12 volts.
