Drag-line mechanism comprises multi-bended drag-line 56, upper block seat 6, lower tumbler seat 7 and first, second, third and fourth guide wheel 1R, 2R, 3R, 4R.

The inside and outside bitter end 561,562 of multi-bended drag-line 56 connects discount 551 respectively and goes up nest 15.

As Fig. 1, Fig. 2, shown in Figure 3, bitter end 561 in the drag-line 56 of these discount 551 direct bearings and go up the first rope section 1S that the contiguous first guide wheel 1R that goes up nest place 15 of pile warp forms drag-line 56; By first guide wheel 1R turnover is the second rope section 2S until the second guide wheel 2R that is hubbed at down nest 23 down; Rotate again by the second guide wheel 2R then and go up and constitute the 3rd rope section 3S so that vicinity goes up the 3rd guide wheel 3R of nest 15; And then turnover and down pile warp be hubbed at down four guide idler 4R on the nest 23 to constitute the 4th rope section 4S; Be pulled in the nest 15 to constitute the 5th rope section 5S, so just form five folding formula rope sections by four guide idler 4R at last for the application of many folding umbrellas.

First and third guide wheel 1R, 3R system is hubbed in the nest 15, or on the installation part at nest 15 places, being embedded on the upper block seat 6 on the nest 15 as shown in Figure 1 and Figure 2.

The second, four guide idler 2R, 4R then are hubbed at down respectively in the nest 23, or the following installation part at nest 23 places, on the lower tumbler seat 7 on the nest 23 under Fig. 1, Fig. 2, Fig. 4, being embedded at shown in Figure 5.

Manage 14 tops in the umbrella on the rod 1 and be provided with two catching grooves 141,142; Upper block seat 6 both sides two lugs 61,62 of buckle in last pipe 14 top catching grooves 141,142 of deriving respectively; Be arranged with the first and third guide wheel cave 63,64 that articulates first and third guide wheel 1R, 3R respectively on it and be equipped with the drag-line hole of shuttling back and forth for drag-line 56; In case of necessity, also can add guiding drag-line 56 in 63 belows, the first guide wheel cave to avoid the dragline groove 630 of drag-line 56 disorders.

First and third guide wheel 1R, 3R are hubbed on the upper block seat 6 in the corresponding first and third guide wheel cave 63,64 by bearing pin 1P, and the two tail end 11P caulkeds of bearing pin 1P are fixed in the pin shaft hole 631,641 at 63,64 two ends, first and third guide wheel cave.

The tail end 11P of bearing pin 1P may be molded to square fixing tightly to fill in each pin shaft hole 631,641.In case of necessity, also can as gluing etc., bearing pin 1P be fixed in the pin shaft hole 631,641 in bearing pin 1P two ends with other related measures.

23 liang of seat boards 233 of following nest are arranged with lughole 234 and form the garter spring 231 of depression 231a; Lower tumbler seat 7 comprises saddle 71 and the adjutage 75 that extends from saddle 71.Saddle 71 is arranged with and articulates second respectively, four guide idler 2R, 4R second, four guide idler cave 72,77 and offer the drag-line crack 711,712 of shuttling back and forth for drag-line 56, spread out respectively to establish and be snapped in down the interior lug 74 of 23 liang of seat boards of nest, 233 lugholes 234 in its both sides; Saddle 71 bottom surfaces coincide with following nest 23 substrates 235.The second, four guide idler 2R, 4R by bearing pin 73 be hubbed at saddle 71 second, in the four guide idler cave 72,77.Adjutage 75 is provided with garter spring groove 76; Adjutage 75 is snapped in down in the depression 231a of nest 23 garter springs 231; and by pile warp on it garter spring groove 76 and down the steel wire 232 of nest 23 garter springs 231 lower tumbler seat 7 is anchored on down on the nest 23; not only can not come off, and hold concurrently and to protect second in the lower tumbler seat 7, four guide idler 2R, 4R.

73 liang of tail ends 731 of bearing pin also can be made into square or rectangle with in two pin-and-holes 720,770 of firmly filling in saddle 71.

Upper and lower wheel stand 6,7 also can be modified into other shapes.

First, second, third and fourth guide wheel 1R, 2R, 3R, 4R last pipe 14 upper ends, in the nest 15 or down in the nest 23; The mode of installation site, orientation, pivot joint; Mechanism, coaxial or disalignment or the like can be varied to various forms, are illustrated as best Installation Modes.

As Fig. 1, shown in Figure 3, the relevant rope section of drag-line 56 is disposed at the first guide wheel 1R both sides as the first rope section 1S and the second rope section 2S; The second rope section 2S and the 3rd rope section 3S are disposed at the second guide wheel 2R both sides; The 3rd rope section 3S and the 4th rope section 4S are disposed at the 3rd guide wheel 3R both sides; The 4th rope section 4S and the 5th rope section 5S are disposed at four guide idler 4R both sides; Be corresponding each to the rope section all each with a guide wheel center balanced configuration, so the pulling force balance opens the utility model, the stroke of drag-line is dynamic equilibrium, smooth and easy not deflection when closing one's umbrella.

When state parachute-opening as shown in Figure 1, press and touch the button 51, retreat locking bolt 52, remove its with umbrella in the buckle of excellent 1 pore 100, launch rod 1 all pipes in the umbrella with the elasticity of deployment spring 3, nest 23 risings under the order are opened umbrella frame assembly 2 and are the parachute-opening shape.Because of the no longer compacting locking bolt 54 down that rises of rod 1 all pipe in the umbrella, make down locking bolt 54 jack-up and also contact slip ring 511 inwalls that rise under the elastic force effect of spring.

When closing one's umbrella, press and touch the button 51, make and press slip ring 511 to reach locking bolt 54 down in the button 51, discount 551 is triped from button hole 111b, to remove the tension force of drag-line 56 and deployment spring 3, shrink umbrella frame assembly 2 by the elastic force that lies in many umbrella colsing springs 4 on the umbrella frame assembly 2, to finish the action that closes one's umbrella.

Since drag-line 56 in umbrella rod 1, on nest 15, down between the nest 23 via above first and third guide wheel 1R, 3R and below second, the circle of four guide idler 2R, 4R is along winding, guiding, makes operation dynamic equilibrium, smooth and easy.And all very convenient and automatic umbrella folding and unfolding that is better than commonly using of the installation, the combination that comprise the drag-line mechanism of first, second, third and fourth guide wheel 1R, 2R, 3R, 4R, upper block seat 6, lower tumbler seat 7 and drag-line 56.
