Abstract
The support tower assembly of the disclosed invention includes an upper tower section and a tower base section pivotally joined together. The tower base section is also pivotally mounted. Both the upper tower section and the lower base section are readily pivoted selectively to be raised and lowered using a leveraged design cable systems and a small winch. A mounting base system is provided to support the tilt-up tower.
Claims35
A collapsible tilt-up support tower assembly for supporting an elevated device comprising:
- (a) a pivoting tower base section having at least three-point support including at least one a free strut support and at least a pair of base section pivoting support legs having free upper ends and lower ends designed to be received in and pivotally attached to spaced pivotal mounts;
- (b) an upper tower section designed to attach to and pivot about a pivot shaft connected with said free upper ends of said base section pivoting support legs, said pivot function being between an upright, raised position and a lowered position;
- (c) an operating mechanism for selectively controlling the pivoting of said tower base section and said upper tower section between an upright, raised position and a lowered position;
- and
- (d) latching systems for selectively fixing said upper tower to said tower base section and said free strut support of said tower base section to a fixed mount to secure the tower assembly in said upright raised position.

A collapsible tilt-up support tower assembly for supporting an elevated device comprising:
- (a) a mounting base system comprising at least three spaced points of support for receiving at least three support legs and including a pair of spaced pivotal mounts and at least one fixed mount spaced from said pivotal mounts;
- (b) a pivoting tower base section having at least three support legs including at least one free leg and a pair of base section pivoting support legs having free upper ends and lower ends designed to be received in and pivotally attached to said pair of spaced pivotal mounts near the lower ends thereof;
- (c) an upper tower section designed to attach to and pivot about a pivot shaft pivotally connected with said free upper ends of said base section pivoting support legs of said base section between an upright raised position and a lowered service position, said upper tower section including an extended aspect for leveraging the pivoting of said upper tower section and connecting to said tower base section;
- (d) a winching mechanism for selectively controlling the pivoting of said tower base section and said upper tower section between an upright raised position and a lowered service position;
- and
- (e) latching systems for selectively fixing said upper tower to said tower base section and said at least one free leg of said tower base section to said fixed mount to secure the tower assembly in said upright raised position.
