Definitions

• Batteries are commonly used to provide power to electronic devices. Typically, batteries are placed within a battery-operated device in a particular orientation to properly complete an electrical circuit. For example, some batteries have a positive terminal at one end of the battery and a negative terminal at the other end of the battery, and the battery must be properly oriented within the device so that the battery terminals engage appropriate contacts of the device. Incorrectly orienting batteries within a device may not only yield an incomplete circuit rendering the battery-operated device unusable, but may also cause permanent damage to the electronic components of the device.
• SUMMARY [0002] Accordingly, the present description provides a battery carriage which may be incorporated into a battery-operated device.
• the battery carriage includes first and second dual-contact assemblies, each of which has a positive contact configured to contact a positive terminal of a battery and a negative contact configured to contact a negative terminal of the battery.
• the positive and negative contacts of the dual-contact assemblies ensure proper electrical connection of the battery to the battery carriage and battery- operated device regardless of how the battery is placed in the battery carriage.
• the battery carriage further includes a body portion to which the first dual- contact assembly is affixed and a separable portion to which the second dual- contact assembly is affixed. The separable portion is selectively moveable into and out of a coupled state with the body portion.
• the first dual-contact assembly and the second dual-contact assembly are held in a spaced relationship to define a receptacle in which the first dual-contact assembly and the second dual-contact assembly are operable to receive and hold opposing ends of the battery.
