Abstract
This mechanical design intends to protect the USB from environmental damage via transfer of linear and circular motion to a housing which houses the USB chip. Unlike other USB housing products with only linear or circular motion, this engineering design does both in order to secure the USB port and enclosing it completely rather than just concealing it, without requiring a separable component. The mechanism is secured in place by applying constant tensile force to the mobile/movable components of the present invention.
Claims
1. A USB portable housing comprising; a base supporting two legs that supports between said legs a plate and shell arrangement; said plate and shell comprise a USB port at one vertical end and a male extrusion at the other end; and said plate and shell are configured to move vertically within the legs with the USB port normally housed within a cavity in the base; this cavity also has a female pocket around the outer edge of the cavity, this female pocket can accommodate the male extrusion; and said legs each contains a tension spring that moderates the vertical movement of said plate and shell; and said tension springs are secured to said shell on its sides, applying constant downward force to said shell towards said base; said plate and shell are also configured to spin 360° between the legs; where the plate and shell are capable to move from a first position where the USB port rests within the cavity to a second deployed position where the male extrusion rests within the female pocket; each leg further contains an outer cavity and an inner cavity that are connected to each other; the outer cavity is closer to the external surface of the leg and the inner cavity with a smaller diameter than the outer cavity is recessed further within the leg, this inner cavity also contains the spring; the outer cavity is configured to accommodate a protrusion or trunnion on both outer edges of said shell, thereby controlling the 360° spin of said plate and shell; the inner cavity is configured to accommodate the protrusion and control with the spring's vertical linear motion within said legs.

DETAILED DESCRIPTION OF THE DRAWINGS
(9) Referring to FIG. 1, the various parts are identified as the Base (1), 2 Legs (2), Plate (3), and Shell (4). These are the parts in relation to the present invention.
(10) Referring to FIG. 2, the present invention can be seen with the Shell (4) and Plate (3) part moving vertically upwards until the USB Port (5) and the Cavity (7) which it was housed in is exposed, which pulls on a tension spring housed within the 2 Legs (2) secured to the Base (1) with a hole on both sides (8). The male extrusion (6) on top of the Shell (4) is also identified.
(11) Referring to FIG. 3, the present invention can be seen rotated at the Axis point located at (9), at the 2 Legs (2) circular outer cavity (18). Here the male extrusion (6) can be seen aligning with the female pocket (10) which will allow the Shell (4) to not slip while in deployed state.
(12) Referring to FIG. 4, the present invention can be seen in its deployed state.
(13) Referring to FIG. 5, the drawing is a detailed diametric and orthographic cross section sketch of the Base (1). The 2 holes which the tension spring is housed in (12) and secured in (13) can be seen in between the 4 machine screw holes (11) which is used to fasten the Base (1) to the 2 Legs (2). The cavity for the USB connector (14) is also identified.
(14) Referring to FIG. 6, the drawing is a detailed diametric and orthographic cross section sketch of the 2 Legs (2). The 2 holes (15) seen on the top right sketch is used to fasten to the holes (11) of the Base (1). The outer cavity (16) of this Part is where the Shell (4) side extrusions (20) sits in, which vertically constrains it for only linear motion, and the inner cavity (17) is where the tension spring is housed (not pictured), serving to secure the Shell (4) in place. A large circular cavity can be found on the top of the outer cavity (18) which is the location where the Shell (4) is able to rotate via circular motion, using its side extrusions (20) as a hinge.
(15) Referring to FIG. 7, the drawing is a detailed diametric and orthographic cross section sketch of the Shell (4), the part which provides the shell for the USB chip. The 2 extrusion (20) found on both sides of the Part is used as the guide for the outer cavity (16) of the 2 Legs (2). A hole (19) can be seen on both of these extrusions (20) which is where the tension spring will be fastened to via another machine screw. In order to have a secure fit with the Plate (3), the Shell (4) also have two ribs (21) on both walls.
(16) Referring to FIG. 8, the drawing is a detailed diametric and orthographic cross section sketch of the Plate (3). The rounded cavity (22) is where the USB connector end faces, and a female rib cavity (23) is also identified, which fits with the ribs (21) found on the Shell (4).
