This invention relates to electronic image frames, and in particular to electronic image frames having an electronics housing portion and a detachable frame portion that is secured in place by a tab and slot mechanism.
Electronic image frames, also known as digital photo frames, are known in the art. Such devices typically consist of an electronic image display (e.g., a liquid crystal display) and its associated electronics, a power supply, a means for operating the functions of the device (e.g., buttons), a means for acquiring and storing image content (e.g., memory card ports, data ports, etc.), and a decorative housing containing the aforementioned components. Some electronic image frames have a detachable decorative frame that surrounds the display, allowing the attachment of different frames to match a particular style or décor. Such a device is disclosed in U.S. Patent Publication No. 20070011929 to Cheng, hereby incorporated by reference in its entirety. A disadvantage of the electronic image frames of the prior art is that they feature multiple tab and slot mechanisms for attaching the frame to the housing. Such a configuration necessarily limits the size and stability of each tab, increases the difficulty and dexterity needed to attach and remove the frame, and increases the overall complexity of the design of both the housing and the frame.
The present invention relates to electronic image frame systems having an electronics housing portion and a detachable frame portion that is secured in place by a single tab and slot mechanism. In preferred embodiments of the present invention, the electronic image frame system includes a power cord. In other embodiments, the electronic image frame system includes a data cable (e.g., Universal Serial Bus “USB” cable, IEEE 1394 “FireWire” cable, RJ-45 “Ethernet” cable, etc.) for communication and data transfer with a computing device. In yet other embodiments, the electronic image frame system includes wireless data transmission capabilities. In some embodiments, the electronic image frame system includes a wired or wireless remote control to facilitate operation of the device.
The electronic image frame systems of the present invention feature an electronics housing portion and a detachable frame portion that is secured in place by a single tab and slot mechanism. In some embodiments of the present invention, the tab is attached to a surface of the housing, and is received in place by a slot in the frame. In preferred embodiments, the width of the tab comprises a substantial portion of the width of the surface of the housing to which it is attached. In particularly preferred embodiments, the width of the tab is at least 50 percent of the width of the surface of the housing to which it is attached. In other embodiments, the width of the tab is between 50 percent and 75 percent of the width of the surface of the housing to which it is attached. In yet other embodiments, the width of the tab is between 75 percent and 100 percent of the width of the surface of the housing to which it is attached. In some embodiments, the tab extends to more than one surface of the housing. In other embodiments, the tab is configured as a unitary ridge protruding from two sides of the housing. In yet other embodiments, the tab is configured as a unitary ridge protruding from three sides of the housing. In some embodiments, the tab is configured as a unitary ridge extending around four sides of the housing. The receiving slot in the frame may be size-matched to the tab. In other embodiments, the slot occupies substantially all of a side of the frame. In yet other embodiments, a single slot spans all four sides of the frame.
