Abstract:
An adjustable support stand for adjusting a height of a device, the device comprising a housing and a cavity in the housing, the support stand comprising:a ratchet casing capable of moving along a linear direction within the cavity of the housing, the cavity having a first inner end and a first outer end for limiting the ability of the ratchet casing to move within the cavity in the linear direction; a ratchet disposed inside the ratchet casing, the ratchet comprising: a plurality of teeth; and a protruding edge for limiting the ability of the ratchet to move in the linear direction, wherein the protruding edge moves between a second inner end and a second outer end of the ratchet casing; a pawl for engaging the teeth of the ratchet, the pawl being connected to the housing at a pivot point for fixing the pawl to the housing and allowing the pawl to rotate about the pivot point, wherein the pawl rotates for engaging and disengaging with teeth of the ratchet; a biasing means for forcing the pawl to rotate towards the teeth of the ratchet about the pivot point; and a base formed on a third outer end of the ratchet for supporting the device on a surface, wherein the ratchet is capable of being pulled outwards from the ratchet casing for raising a height of the device, and the ratchet casing is capable of being pulled outward to disengage the pawl from the teeth of the ratchet for lowering the height of the device.
