A portable flash drive with snap hook for attaching the drive to an object such as a key, key chain, etc. is disclosed herein. The portable flash drive includes a housing defining a chamber, a memory unit disposed in the chamber of the housing, and a slot hook attached to an end of the housing. The slot hook includes an interior aperture, a blocking end, a pivoting end, and an opening therebetween, and a spring lever having a first arm and second arm of staggered lengths extending parallel from opposite ends of an abutment segment therebetween, the first and second arms attached to the hook at the pivoting end of the hook such that the spring lever is biased to a closed position across the opening.
1. A portable flash drive, comprising:
a housing defining a chamber;
a memory unit disposed in the chamber of the housing;
a slot hook attached to an end of the housing, the slot hook including:
a hook defining an interior aperture and having a blocking end, a pivoting end, and an opening therebetween; and
a spring lever having a first arm and second arm of staggered lengths extending parallel from opposite ends of an abutment segment therebetween, ends of the first and second arms attached to the hook at the pivoting end of the hook so as to form a vertical displacement of the ends of the first and second arms such that the spring lever is biased to a closed position across the opening due to the vertical displacement of the ends of the first and second arms; and
the flash drive further comprising a retaining clip having a bottom portion, a top portion, a back wall segment interconnecting the bottom portion to the top portion, and a front wall segment connected to the bottom portion, the memory unit frictionally secured between the bottom portion and the top portion and the front wall segment preventing the memory unit from sliding out from between the bottom portion and the top portion, the retaining clip positioned and retained within the chamber of the housing.
2. The portable flash drive of claim 1 , wherein the spring lever is rotationally positionable to an open position by application of an external force to the spring lever.
3. The portable flash drive of claim 2 , wherein rotating the spring lever creates a torsion force in the abutment segment of the spring lever.
4. The portable flash drive of claim 1 , wherein the first arm comprises an upper segment, a lower segment, and a first end opposite the abutment segment, the second arm comprises an upper segment, a lower segment, and a second end opposite the abutment segment, and wherein the upper and lower segments of the first arm and the upper and lower segments of the second arm each form an angle less than 180 degrees.
5. The portable flash drive of claim 4 , wherein the hook further comprises a first and second holes formed in the pivoting end of the hook.
6. The portable flash drive of claim 5 , wherein the spring lever is attached to the hook by insertion of the first and second ends of the first and second arms of the spring lever into first and second holes of the hook.
7. The portable flash drive of claim 5 , wherein the first and second holes of the hook are vertically aligned and staggered.
8. The portable flash drive of claim 1 , wherein the housing includes an open end, and the open end of the housing and memory unit define a universal serial bus (SB) interface.
9. The portable flash drive of claim 1 , wherein the housing further comprises an inwardly biased tab, and the snap hook further comprises a connector attached to the hook and including a niche to receive the tab.
10. The portable flash drive of claim 1 , wherein the snap hook further comprises a connector with one or more engagement protrusions to engage one or more engagement recesses formed on the top portion of the retaining clip for retaining the retaining clip and the memory unit in the housing.
