Pen-like universal serial bus (USB) flash drive with deploying and retracting functionalities

A universal serial bus (USB) flash drive pen device, comprising:

• a USB plug assembly having a flash controller and a flash memory device;
• a pusher assembly including a block having a tab disposed thereon;
• and
• a housing for housing at least a portion of the USB plug assembly and the pusher assembly, the housing having a chamber disposed on an inner wall of the housing, and the chamber having a deployed angled corner and a retracted angled corner disposed therein,
• wherein when the USB plug assembly is deployed, the block is pushed forward through the chamber, which in turn pushes the USB plug assembly to be deployed through a front end of the housing, wherein the tab of the block is interlocked with the deployed angled corner of the chamber to maintain the USB plug assembly in a deployed position, and
• wherein when the USB plug assembly is retracted, the tab of the block is unlocked from the deployed angled corner and pushed backward towards to the back end of the housing which in turn retracts the USB plug assembly into the housing, wherein the tab of the block is interlocked with a retracted angled corner of the chamber to maintain the USB plug assembly in a retracted position.

A universal serial bus (USB) flash drive pen device, comprising:

• a USB plug assembly having a flash controller and a flash memory device;
• an end cap for holding the USB plug assembly, the end cap including a pusher segment and a support segment extended from the pusher segment, wherein the USB plug assembly is securely disposed on the support segment;
• a spring clip having a center ring, a first arm extended from the center ring, and a second arm extended from the center ring, the first arm ended with an end tip and the second arm ended with a front tip;
• and
• a housing for housing at least a portion of the USB plug assembly and the end cap, the housing having one or more tracks to form a deployed path, a retracted path, and a lock groove therein,
• wherein when the USB plug assembly is deployed, the pusher segment of the end cap is pushed forward causing the front tip of the spring clip traveling forward within the deployed path to deploy the USB plug assembly through a front end of the housing while the end tip is secured on a surface of the end cap, wherein the front tip of the spring clip is interlocked with the lock groove to maintain the USB plug assembly in a deployed position, and
• wherein when the USB plug assembly is retracted, the pusher segment of the end cap is pushed again causing the front tip of the spring clip traveling backward within the retracted path while the end tip is secured on the surface of the end cap to retract the USB plug assembly from the front end of the housing.
