Patent ID: 7967273

Claim:
A support stand, comprising: a base; a rotatable bracket; two parallel first connecting members; two parallel second connecting members; a first hinge assembly; and a second hinge assembly; wherein both the first and second hinge assemblies together with the two first connecting members and the two second connecting members connect the rotatable bracket with the base; the first hinge assembly has a first pivotal shaft and a restricting member sleeved on the first pivotal shaft; the second hinge assembly has a second pivotal shaft and a restricting member sleeved on the second pivotal shaft; the first pivotal shaft is non-rotatably engaged with the second pivotal shaft, and aligned in a substantially straight line; wherein two restricting protrusions are coplanarly formed on opposite sides of each restricting member; one restricting protrusion resists the first connecting member, the other restricting protrusion resists the second connecting member, thus defining a rotating angle range of the rotatable bracket.
