Brief description of the drawings
Accompanying drawing 1 is schematic structural view of the invention.
1 is lower fulcrum bar in figure, and 3 is second connecting rod, and 5 is that corner amplifies pole, and 7 is first connecting rod, and 9 is fastening sector
Wheel, 11 is upper rack posts.
Specific embodiment
The automatic both shoulders back of the body umbrella stand for keeping umbrella balance vertically, including upper rack posts (11), lower fulcrum bar (1), with Braces hanged over tow shoulders
Backrest (13), upper rack posts (11) are with the first backrest fulcrum shaft O1It is hinged；Band extension spring between upper rack posts resistance arm and backrest (13)；Under
Pole (1) is with the second backrest fulcrum shaft O2It is hinged.Therefore, upper rack posts can only be around the first backrest fulcrum shaft O by limitation1Rotate, draw
The pulling force of spring makes upper rack posts Connectable umbrella pommel (namely upper rack posts resistance arm end) be drawn close to backrest.Lower fulcrum bar also can only be around
Two backrest fulcrum shaft O2Rotate.Improvements of the invention are also to include that corner amplifies pole (5).It is same that the corner amplifies pole
3rd backrest fulcrum shaft O3It is hinged.Therefore, corner amplification pole also can only be around the 3rd backrest fulcrum shaft O3Rotate.
Amplify pole (5) with upper rack posts (11), corner respectively and be hinged in first connecting rod (7) two ends.Therefore first connecting rod two ends
Can be rotated respectively around pin joint D and pin joint C.
Amplify pole (3) with lower fulcrum bar (1), corner respectively and be hinged in second connecting rod (3) two ends.Therefore, second connecting rod two ends
Can be rotated respectively around pin joint A and pin joint B.
First connecting rod amplifies the backrest fulcrum shaft O of pin joint C distances the 3rd of pole with corner3Put with corner than second connecting rod
The backrest fulcrum shaft O of pin joint B distances the 3rd of big pole3It is long.That is, straight line CO3Distance is than straight line BO3It is long.Therefore, when
Corner amplifies pole (5) around the 3rd backrest fulcrum shaft O3When rotating and turning over an angle, the thread of C points movement is moved than B point
Thread it is long.So, when lower fulcrum bar (1) is around the second backrest fulcrum shaft O2When turning over an angle [alpha], corner amplifies pole will be around
The second backrest fulcrum shaft O3Rotation, the angle of rotation will be β=α × AO2/BO3.And upper rack posts (11) will be around the first backrest
Fulcrum shaft O1Angle γ=β × CO3/DO1.β is substituted into and obtains final product γ=α (AO2/BO3)(CO3/DO1).If AO2With DO1Length is big
Cause is equal, then γ ≈ α (CO3/BO3).So, corner amplifies the pin joint C and pin joint B on pole (5), plays and allows lower fulcrum bar
(1) make α angular turns and zoom into upper rack posts (11) must and then to make the effect of γ angular turns.
For the angle γ for controlling upper rack posts to rotate, corner can be allowed to amplify pole (5) with no less than two same second
The optional pin joint that connecting rod (3) end is hinged.When using, one of them pin joint of selection is hinged with second connecting rod as needed.
Likewise, for the angle γ for controlling upper rack posts to rotate, corner can be allowed to amplify pole (5) with no less than two
The optional pin joint that same first connecting rod (7) end is hinged.When using, selecting one of them same first connecting rod of pin joint as needed
It is hinged.
Fixed using with a certain size active force to will be turned over the upper rack posts after an angle, the first backrest fulcrum shaft
O1On can fasten sector gear (9) so that compact conformation, sector gear is fixed together with backrest (13).When using, can
To install hammer pendulum and tongue latch additional on upper rack posts.
When using, umbrella handle is fixed together with upper rack posts, unfurled an umbrella, backrest worn on the back.Lower fulcrum bar is inserted into
Among the collar, then the waistband plug that one is fixed on the collar is inserted on waistband.Different height and different motion in reality
The people of custom, its angle for bending over to be turned over to work waist of bending is different.Appropriate pin joint may be selected, to control upper branch
The bar angle to be rotated.When work above the waist is bent down when bending over, lower fulcrum bar under effect, produces rotation in waistband between backrest
And turn over an angle.Now, corner amplifies the corner size to upper rack posts of pole with control, forces upper rack posts to rotate rule
Fixed angle, allows upper rack posts to keep vertical.Extension spring is stretched.Bowed from bending over above the waist when returning back to standing state, extension spring is by upper branch
Bar retracts vertical state, while lower fulcrum bar is slided in the collar transfers back to initial angle.
