Abstract: The present invention provides a portable support device adapted for being disassembled into segments for packing and being readily assembled. The support device in a first embodiment has a base block to which a pair of arms is assembled and to which a segmented pole is mounted in vertical orientation to support a mosquito net. In a second embodiment, an arm is assembled to a beam to define a horizontal plane and a segmented pole is assembled to the beam in a vertical orientation without use of a connecting block. In third and fourth embodiments, a pair of horizontal members are connected to each other and to a vertical support pole by a rigid connector. According to a third embodiment, a junction piece having two studs extending in a horizontal plane and a third stud in vertical orientation with an arm mounted to each of the horizontal studs and a pole mounted to the vertical stud to form a support apparatus.
