Motorized collapsible platform assembly

A collapsible platform assembly adapted to be secured to a vertically extending surface such as a wall and having a planar work surface which is adjustable between a horizontal work position and a vertical storage position comprising:

• a single vertical support member having an upper end and a lower end, said lower end having a cylindrical coaxial base member extending therefrom, said base member attached to an inner coaxial member, said vertical support member further including an outer coaxial member axially slidable upon said inner member, said outer coaxial member having an outer surface and an inner surface, said upper end of said vertical support member having a horizontal support ledge attached thereto,
• said horizontal support ledge being attached to said wall at one side and being hingedly connected to said planar work surface at an opposing side,
• a source of motive power attached to said outer surface of said outer coaxial member, said source of motive power being operably connected to a first end of an axially reciprocable drive shaft, the drive shaft having an opposing end connected to said work surface thereby allowing adjustment of the position of said work surface in accordance with the actuation of said source of motive power.
