2. Description of the Related Art
Electronic device with USB interface has gained immense popularity in recent years. Many businessmen and professional find USB very useful in their work. A Universal Serial Bus (USB) is a small portable memory storage device that is used on computers and other digital devices to transfer data using a USB cable. One of the most desirable features in the USB is that, the computer does not need to be powered off and restart to attach or remove the USB.
Today electronic device with USB interface comes in various attractive shapes, colors, and sizes. Many USB peripherals utilize a protective cover to protect the connecting portion. A common problem associated with most USB devices is the possibility of losing the protective cover due to its small size which may cause physical damage to the USB device. Moreover, it increases the susceptibility to slipping off of the protective cover during normal handling, transport and storage.
With the increased use of USB, various extension and retraction mechanisms are provided for the connecting portion. These mechanisms utilize a sliding button to extend the connector from an enclosure of the USB and to retract the connector when not in use. (See prior art U.S. Pat. No. 6,979,210, Regen, et al.) The operation is inconvenient for an end user. Furthermore, such mechanisms require multiple parts such as button and are complex for manufacturing.
In order to address the need of protection of the connecting portion, Some USB devices have been developed with a sheath for slidably receiving the main body. A positioning component in the sheath fixes the main body when the connection portion is protruded and an elastic component in the sheath presses the main body to store the connecting portion. (See prior art U.S. Pat. No. 7,104,814, She, et al.) Frequent use of such device decreases the durability of the elastic component. Further, the damage of the elastic component makes the device useless.
Many attempts are made to utilize a complex sliding mechanism which includes multiple moving parts with a press button. The sliding mechanism is ejected by pressing on the button. This approach is difficult and very expensive to manufacture.
Some other USB devices utilize a spring to keep the button protruded. Utilization of such a spring increases the thickness of the device due to the implementation of the spring mechanism.
Hence, it can be seen, that there is a need for an electronic device that is capable of eliminating the sliding button and/or elastic component for the protection, capable of utilizing fewer parts. Moreover, the needed device would be durable, economical, and easy to manufacture.
To minimize the limitations found in the prior art, and to minimize other limitations that will be apparent upon the reading of the specifications, the present invention provides an electronic device having a sliding protective top case that allows the protection of a connector. The electronic device comprises a main body, a connector positioned at a proximal end of the main body, a bottom case coupled to the main body at a distal end, and a top case slidably located opposite to the bottom case. The electronic device further comprises a first cantilever locking arm and a second cantilever retaining arm on at least one side of the main body; wherein the top case is slid towards at least one end of the main body to expose and protect the connector.
In another aspect of the present invention, a method in accordance with the present invention is a method of protecting and exposing a connector comprising of sliding a top case towards a bottom case to achieve an open state, and sliding the top case towards the connector to achieve a closed state; wherein the top case and the bottom case are immediately adjacent to each other when the top case is in the open state and are distally separated when the top case is in the closed state.
One objective of the invention is to provide an electronic device with a slidable protective top case that is capable of exposing and covering the connector.
Another objective of the invention is to provide an electronic device with a stationary main body and a movable top case.
A third objective of the invention is to provide an electronic device featuring a first cantilever locking arm on at least one side of a main body that includes an open locking mechanism and a close locking mechanism for maintaining a top case in an open state and a closed state respectively.
Yet another objective of the invention is to provide an electronic device featuring a second cantilever retaining arm on at least one side of a main body that is capable of retaining a top case on the main body.
Still another objective of the invention is to provide an electronic device featuring a simple design that facilitates ease of manufacturing.
It is also the objective of the invention to provide an electronic device with two holes on a bottom case, each for receiving a strap means for carrying the electronic device.
These and other advantages and features of the present invention are described with specificity so as to make the present invention understandable to one of ordinary skill in the art.

Electronic device is shown in
The electronic device 100 in this current exemplary embodiment may have a removable plastic window on the top case 112 in order to insert small graphical card. Moreover, although the top case 112 and the bottom case 108 of the electronic device 100 may be made out of a plastic material as the most common material, these may also be made out of any biodegradable material or any other material capable of offering protection to the connector 104 all without departing from the scope of the present invention.
Finally,
Top case 112 may be moved towards the bottom case 108 to expose the connector 104 and achieve the open state 114. The top case 112 and the bottom case 108 in this current exemplary embodiment may be immediately adjacent to each other when the top case 112 is in the open state 114. The connector 104 may be able to connect to the external device (not shown) in this open state 114.

As seen in
First cantilever locking arm 902 may include an open locking mechanism and a close locking mechanism for maintaining the top case 908 in the open state 912 and the closed state (not shown) respectively. Second cantilever retaining arm 904 may retain the top case 908 on the main body 906.
The first cantilever locking arm 902 and second cantilever retaining arm 904 are strong enough that when the connector 910 is covered, the top case 908 will not accidentally slide back towards the bottom case (not shown).
