Abstract
This invention discloses a cantilever umbrella with duo-arc tubes in a sliding-sleeve configuration, which includes: a base support for the arched tubes, a lower arched tube, an upper arched tube, a main canopy frame and a handle assembly. The upper arched tube is slidably connected with the lower arched tube through the handle assembly; the umbrella's main canopy frame is installed at the distal end of the upper arched tube through a canopy base junction; a mounting channel cooperating with the upper arched tube is provided on the inner surface of said lower arched tube—said mounting channel, once mated with the upper arched tube, leads to a semi-covered structure over the upper arched tube; and a winding wheel is provided to control the open and close of the main canopy frame.
Claims21
A cantilever umbrella, comprising an arched spine, said arched spine comprising a lower arched tube and an upper arched tube connected through a handle assembly with said upper arched tube situated at a distal end of said arched spine and connected through a canopy base junction to a main canopy frame, wherein one of said lower arched tube and upper arched tube is arranged to provide an open mounting channel that receives and only partly wraps around the other arched tube in partial but not full coverage of its outer surface, such that the upper arched tube slides along the lower arched tube when driven by said handle assembly;
- and
- wherein said handle assembly comprises a handle shell main body, a winding wheel set, and a locking mechanism assembled in cooperation with the handle shell main body;
- said handle shell main body is slidably connected to said lower arched tube, said locking mechanism is configured to be capable of locking positions between said handle shell main body and said lower arched tube, thereby effectively locking the connected upper arched tube at any desired position along the lower arched tube;
- and said winding wheel set is configured to control the open and close of the main canopy frame.
A cantilever umbrella, comprising a lower arched tube, an upper arched tube, a main canopy frame and a handle assembly, wherein said upper arched tube is slidably connected with said lower arched tube through said handle assembly, and said main canopy frame is installed at a distal end of said upper arched tube through a canopy base junction, wherein one of said lower arched tube and upper arched tube is arranged to provide an open mounting channel that receives and only partly houses wraps around the outer surface of the other arched tube, forming partial but not full coverage by the former over the latter tube when the two are collapsed together.
An outdoor umbrella, comprising a spine connected at its distal end to a canopy frame and at its proximal end to a tube support, said tube support comprising a mounting base, an inner vertical pipe, an outer vertical pipe and a locking structure, wherein said inner vertical pipe is fixedly attached to a top of said mounting base, said outer vertical pipe is fixedly attached to said spine and sleeving over an outer surface of said inner vertical pipe, and said locking structure disposed between said inner vertical pipe and said outer vertical pipe, said spine comprising a straight column affixed at its proximal end to said outer vertical pipe and said outdoor umbrella is a Roman umbrella;
- wherein said locking structure comprises a fluted disk comprising toothed grooves, a rotating sleeve piece and a locking assembly, said fluted disk affixed to a top of said inner vertical pipe, said rotating sleeve piece affixed to said outer vertical pipe and rotating in cooperation with said fluted disk, and said locking assembly disposed on said outer vertical pipe and capable of locking and unlocking said outer vertical pipe as parts of said locking assembly insert into or disengage from toothed grooves of said fluted disk, thereby effecting 360 degrees of rotation and locking at any of those degrees of said outer vertical pipe therefore said spine and said canopy relative to said inner vertical pipe;
- and
- wherein said mounting base comprises a counterweight seat and two elongated pieces installed therein, said counterweight seat comprises at least two counterweight blocks configured to have, in opposing side faces, accommodating housing grooves such that when said two counterweight blocks are closed together, a housing cavity is formed between said two counterweight blocks, wherein said two elongated pieces are arranged in the housing cavity in an intersecting fashion.
An outdoor umbrella, comprising a spine connected at its distal end to a canopy frame and at its proximal end to a tube support, said tube support comprising a mounting base, an inner vertical pipe, an outer vertical pipe and a locking structure, wherein said inner vertical pipe is fixedly attached to a top of said mounting base, said outer vertical pipe is fixedly attached to said spine and sleeving over an outer surface of said inner vertical pipe, and said locking structure disposed between said inner vertical pipe and said outer vertical pipe, said spine comprising a straight column affixed at its proximal end to said outer vertical pipe and said outdoor umbrella is a Roman umbrella;
- wherein said locking structure comprises a fluted disk comprising toothed grooves, a rotating sleeve piece and a locking assembly, said fluted disk affixed to a top of said inner vertical pipe, said rotating sleeve piece affixed to said outer vertical pipe and rotating in cooperation with said fluted disk, and said locking assembly disposed on said outer vertical pipe and capable of locking and unlocking said outer vertical pipe as parts of said locking assembly insert into or disengage from toothed grooves of said fluted disk, thereby effecting 360 degrees of rotation and locking at any of those degrees of said outer vertical pipe therefore said spine and said canopy relative to said inner vertical pipe;
- further characterized as:
- said locking assembly comprises a fixed sleeve seat and a wrench, wherein:
- said fixed sleeve seat is affixed to said outer vertical pipe, a first receding groove and a second receding groove which are in communication with each other are provided in said fixed sleeve seat and said outer vertical pipe, respectively;
- said wrench is rotatably connected to said fixed sleeve seat, and a locking piece is arranged at an inner end of said wrench, said locking piece passing through said first receding groove and said second receding groove, and extending into an inner cavity of said outer vertical pipe;
- and a locking groove that mates with the grooved teeth of said fluted disk is provided in an outer end of said locking piece;
- and
- wherein said wrench is configured with, in its rotating end, a mounting groove, a second torsion spring is embedded in an inner wall of said mounting groove with an inner end of the second torsion spring affixed to said inner wall of said mounting groove, and an outer end of said second torsion spring abutting against an outer vertical face of said fixed sleeve seat.
