Detailed description of the invention
Please first consult Fig. 1 and Fig. 4, the curtain without stretching wire 10 shown in figure includes the underbeam 14 of the relative upper beam 12 of a upper beam 12, and one is located at curtain body 16 between upper and lower beam 12,14.Referring again to Fig. 2, the curtain body detent mechanism 18 of the present invention the 1st embodiment includes holder 20, two resistance unit 30,2 first drive 41, two transmission rope 44,2 second drive 51, and a wind spring 54.
Holder 20 to be installed in upper beam 12 and to have upper mounted plate 21 and a bottom plate 23, is joined to each other between upper and lower fixing plate 21,23.
Each resistance unit 30 has unidirectional ratchet 31, resistance shell fragment 32, and a resistance wheel 33.Unidirectional ratchet 31 is between one first retaining wall 25 and one second retaining wall 26 of holder 20 of holder 20 and between the upper and lower fixing plate 21,23 being hubbed at holder 20 with its one end, the side mask of unidirectional ratchet 31 has a curved portions 312, curved portions 312 is connected to the first retaining wall 25 of holder 20, make unidirectional ratchet 31 when being subject to External Force Acting can between first, second retaining wall 25,26 elasticity beat; Resistance shell fragment 32 has fixed arm 321, elastic arm 322 and a friction part 324, the two ends of fixed arm 321 are fixed between the upper and lower fixing plate 21,23 of holder 20, wherein one end of elastic arm 322 self-retaining arm 321 is extended, and friction part 324 is located at the end of elastic arm 322; Resistance wheel 33 has resistance wheel shaft 34, one-way fluted disc 35 in the present embodiment, and a frictional disk 36, resistance wheel shaft 34 is located between the upper and lower fixing plate 21,23 of holder 20 rotationally, one-way fluted disc 35 be connected to the bottom of resistance wheel shaft 34 and bridle joint in unidirectional ratchet 31, make one-way fluted disc 35 to make one-directional rotation, frictional disk 36 is connected to the top of resistance wheel shaft 34 and is connected to the friction part 324 of resistance shell fragment 32.
Each first drive 41 has 2 first transmission fluted discs 42 (as long as in fact at least one) and and is connected to the first power axle 43 between this 2 first transmission fluted disc 42, between the upper and lower fixing plate 21,23 being located at holder 20 when assembling by the first power axle 43, after assembly is completed, this 2 first drive 41 can be arranged between this two resistance wheel 33 in the mode be spaced.
As shown in Figures 3 and 4, the first power axle 43 of the first drive 41 is fixed in one end of each transmission rope 44, and passes curtain body 16 with the other end again and be fixed on underbeam 14 after enclosing around the resistance wheel shaft 34 1 of resistance wheel 33.
Each second drive 51 has 2 second transmission fluted discs 52 (as long as in fact at least one) and and is connected to the second power axle 53 between this 2 second transmission fluted disc 52, between the upper and lower fixing plate 21,23 being located at holder 20 when assembling by the second power axle 53, the the second transmission fluted disc 42 making this 2 second drive 51 each other bridle joint together outside, allow simultaneously this 2 second drive 51 the second transmission fluted disc 42 again bridle joint in the first transmission fluted disc 42 of the first drive 41, make the first drive 41 can with the second drive 51 synchronous axial system.
Wind spring 54 connects the second power axle 53 of this 2 second drive 51 and is selectively wound in the second power axle 53 of one of them the second drive 51.
When curtain body 16 will be launched, as shown in Figure 4, first exert a force underbeam 14 pulled down, make each transmission rope 44 stretch by underbeam 14, can resistance wheel 33 and the first drive 41 be first driven to rotate in the process that transmission rope 44 is stretched, then the first drive 41 can drive the second drive 51 to rotate again, wind spring 54 is furled to another one second drive 51 and the elastic-restoring force of accumulation itself from one of them second drive 51, on the other hand, friction effect by producing between frictional disk 36 and the friction part 324 of resistance shell fragment 32 in the process that resistance wheel 33 rotates, make curtain body 16 can stably action, once discharge the pulling force bestowing underbeam 14 after being launched completely by curtain body 16 again, resistance wheel 33 at this time can be stopped operating by the bridle joint relation between unidirectional ratchet 31 and one-way fluted disc 35, thus, transmission rope 44 is understood by the frictional resistance between resistance wheel 33 and is presented the state of standing balance between the elastic-restoring force of wind spring 54, curtain body 16 is made to remain on deployed condition.
When curtain body 16 will be folded, as shown in Figure 5, first exert a force and underbeam 14 up promoted, transmission rope 44 is made to become lax state and the frictional resistance reduced between resistance wheel 33, the elastic-restoring force of wind spring 54 at this time can force this 2 second drive 51 simultaneously to rotate backward with the thrust of user, the first drive 41 can be driven again to rotate in the process that the second drive 51 rotates, first drive, 41 pairs of transmission ropes 44 are furled, until discharge the thrust bestowing underbeam 14 when curtain body 16 folds completely again, transmission rope 44 is made again tightly to be around in resistance wheel 33, at this time just can present the state of standing balance between the elastic-restoring force of wind spring 54 and the frictional resistance between transmission rope 44 and resistance wheel 33 once again, curtain body 16 is made to remain on collapse state.
It should be added that at this, the present invention structurally can have different change, as shown in Figure 6, the resistance wheel shaft 64 of resistance wheel 63 by two transmission ropes 44 institutes around, between two transmission ropes 44 separate by the frictional disk 65 of resistance wheel 63 and come, and, article two, one end of transmission rope 44 is connected to first drive 61 jointly, in addition, linked together between two the second drives 62 by two panels wind spring 54, structural allocation so can coordinate large-sized curtain body to use.
In sum, curtain body detent mechanism 20 of the present invention mainly utilizes the frictional resistance that produces between transmission rope 44 and resistance wheel 30 and the bridle joint relation between unidirectional ratchet 31 and resistance wheel 33 and provides good locating effect to curtain body 16, reaches effectively to solve curtain body rise problem after deployment and the sagging problem when folding the object increasing ease of use.
