Dependent claims

A collapsible multi-storied parking and/or displaying rack comprising:

at least two vertically spaced parking/displaying members each of which includes a first end, two opposite sides and a second end;
at least one vertically moving mechanism mounted between said two parking/displaying members for moving in parallel said two members apart from or toward each other;
and
at least one positioning mechanism mounted on said moving mechanism and capable of maintaining said two members in a vertically spaced relationship, said positioning mechanism including a first piece having a first end pivotally fixed to a first point of said moving mechanism and a second end having a positioning hole, a second piece connected to said first piece having a first end pivotally fixed to a second point of said moving mechanism, an intermediate positioning hole on said second piece capable of being aligned with said positioning hole of said first piece, and a second end of said second piece being pivotally connected to said second end of said first piece;
and
a positioning pin device capable of being inserted into said positioning holes of said first and second pieces;
wherein said moving mechanism includes:
an oil cylinder enabling said two members to be moved apart from or toward each other,
a pair of first linking pieces respectively disposed on said two sides of said each member and each of which includes a first end pivotally and slidably attached to an upper one of said members near said first end of said upper member, and a second end pivotally fixed to a most adjacent lower one of said members near said second end of said adjacent lower member;
and
a pair of second linking pieces respectively disposed on said two sides of said each member and each of which includes a first end pivotally and slidably attached to said adjacent lower member near said first end of said lower member, and a second end pivotally fixed to said upper member near said second end of said upper member.
