An apparatus for securing a computing device relative to a platform, the apparatus comprising:
- a base assembly configured to secure to the platform, and having a base connector defining a first axis of the apparatus relative to the platform;
- an oblique arm assembly having a lower connector and an upper connector, the lower connector coupled to the base connector along the first axis and configured to rotate at least partially about the first axis, and the upper connector defining a second axis of the apparatus generally parallel with the first axis;
- a power arm assembly having a lower connector and an upper connector, the lower connector of the power arm assembly coupled to the upper connector of the oblique arm assembly along the second axis and configured to rotate at least partially about the second axis, the upper connector of the power arm assembly defining a third axis of the apparatus generally parallel with the second axis, the lower connector of the power arm assembly includes a fixed pin;
- a head assembly having a head and a coupling, the coupling coupled to the upper connector of the power arm assembly along the third axis and configured to rotate at least partially about the third axis;
- and
- a board assembly coupled to the head of the head assembly and configured to secure to the computing device;
- wherein the coupling of the lower connector of the power arm assembly and the upper connector of the oblique arm assembly forms a first switch mechanism configured to enable the power arm assembly to be unlocked relative to the oblique arm assembly, to be locked in place relative to the oblique arm assembly rotatable a first degree or rotatable a second degree relative to the oblique arm assembly,
- the first switch mechanism includes components of the oblique arm upper connector:
- a powder sleeve hole, a powder sleeve located within the powder sleeve hole, a pair of pins, a pair of small pressure springs, a pair of holes associated with the oblique arm upper connector, a pair of features associated with the powder sleeve of the oblique arm upper connector, a knob assembly including a knob and an indicator, a pressure cap, a first-degree indicator and a second-degree indicator,
- the fixed pin of the lower connector of the power arm assembly includes a first-degree groove and a second-degree groove, wherein the fixed pin is configured to fit within and couple with the powder sleeve of the upper connector of the oblique arm assembly, the fixed pin functions together with the first switch mechanism to set range of degree of rotation of the power arm assembly relative to the oblique arm assembly along the second axis,
- the components of the first switch mechanism are arranged and aligned relative to each other so that when the knob assembly is placed at a first location, the biasing force of the pair of small pressure springs maintain the pair of pins in a retracted position relative to the corresponding pair of holes associated with the oblique arm assembly upper connector and with the corresponding pair of features of the powder sleeve associated with the oblique arm upper connector, wherein when the pair of small pressure springs is in the retracted position, the fixed pin of the power arm assembly is unlocked from the oblique arm assembly upper connector and the power arm assembly may be vertically displaced along the second axis and decoupled from the oblique arm assembly,
- when the knob cover is rotated to align the indicator on the knob assembly with the first-degree indicator, a pin arc of the knob engages the head or arc of a first pin of the pair of pins of the first switch mechanism and advances the first pin through a first hole of the pair of holes of the upper connector of the oblique arm assembly and through a first feature of the pair of features of the powder sleeve of the upper connector of the oblique arm assembly, the shaft of the first pin is placed in the first-degree groove of the fixed pin of the power arm assembly, accordingly the power arm assembly can rotate a degree corresponds to the first degree about the second axis, wherein in this state the fixed pin of the power arm assembly is locked with the upper connector of the oblique arm assembly and the power arm assembly cannot be removed from the oblique arm upper connector,
- when the knob assembly is rotated to align the indicator of the knob assembly on with the second-degree indicator, a pin arc of the knob engages the head or arc of a second pin of the pair of pins of the first switch mechanism and advances the second pin through a second hole of the pair of holes of the upper connector of the oblique arm assembly and a second feature of the pair of features of the powder sleeve of the upper connector of the oblique arm assembly, the shaft of the second pin is placed in the second-degree groove of the fixed pin of the power arm assembly, accordingly the power arm assembly can rotate a degree corresponds to the second degree about the second axis, wherein in this state the fixed pin of the power arm assembly is locked with the upper connector of the oblique arm assembly and the power arm assembly cannot be removed from the oblique arm upper connector.
