Position mechanism 18 includes a fixed seat 20, two resistance units 30,2 first drives 41, two transmission ropes 44,2 second drives
51, and a wind spring 54.
Fixed seat 20 is installed in upper beam 12 and has a upper mounted plate 21 and a bottom plate 23, upper and lower fixing plate 21,
It is joined to each other between 23.
Each resistance unit 30 has a unidirectional ratchet 31, a resistance shell fragment 32, and a resistance wheel 33.Unidirectional ratchet 31 is situated between
Between one first retaining wall 25 of fixed seat 20 and one second retaining wall 26 of fixed seat 20 and fixed seat 20 is hubbed at its one end
Upper and lower fixing plate 21,23 between, the one side of unidirectional ratchet 31 has a curved portions 312, and curved portions 312 are connected to fixation
Seat 20 the first retaining wall 25 so that unidirectional ratchet 31 when being acted on by external force can between first, second retaining wall 25,26 bullet
Property beat；Resistance shell fragment 32 has a fixed arm 321, an elastic arm 322 and a friction portion 324, and the two ends of fixed arm 321 are fixed on
Between the upper and lower fixing plate 21,23 of fixed seat 20, wherein one end of the self-retaining arm 321 of elastic arm 322 is extended, friction portion 324
Located at the end of elastic arm 322；Resistance wheel 33 has a resistance wheel shaft 34, an one-way fluted disc 35 in the present embodiment, and one rubs
Disk 36 is wiped, resistance wheel shaft 34 is rotatably arranged between the upper and lower fixing plate 21,23 of fixed seat 20, and one-way fluted disc 35 is connected to
The bottom of resistance wheel shaft 34 and bridle joint is in unidirectional ratchet 31 so that one-way fluted disc 35 can only make one-directional rotation, and frictional disk 36 is connected
In the top of resistance wheel shaft 34 and it is connected to the friction portion 324 of resistance shell fragment 32.
There are each first drive 41 2 first transmission fluted discs 42 (as long as actually at least one) to be connected to one
The first power axle 43 between the 2 first transmissions fluted disc 42, fixed seat 20 is located in assembling by the first power axle 43
Upper and lower fixing plate 21,23 between, after assembly is completed, 2 first drive 41 can be set in the way of being spaced
Between two resistance wheel 33.
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
Curtain 16 is passed with the other end again after the circle of resistance wheel shaft 34 1 of resistance wheel 33 and underbeam 14 is fixed on.
There are each second drive 51 2 second transmission fluted discs 52 (as long as actually at least one) to be connected to one
The second power axle 53 between the 2 second transmissions fluted disc 52, fixed seat 20 is located in assembling by the second power axle 53
Upper and lower fixing plate 21,23 between, make 2 second drive 51 second be driven fluted disc 52 each other bridle joint together outside,
Allowing the second of 2 second drive 51 to be driven fluted disc 52 simultaneously, bridle joint is driven fluted disc 42 in the first of the first drive 41 again, makes
Obtaining the first drive 41 can be with the synchronous axial system of the second drive 51.
Wind spring 54 connect the second power axle 53 of 2 second drive 51 and be selectively wound in one of them the
Second power axle 53 of two drives 51.
When curtain 16 to be deployed, as shown in figure 4, exerting a force the pulled down of underbeam 14 first, make each transmission rope 44 by under
Beam 14 is stretched, and can first drive resistance wheel 33 to be rotated with the first drive 41 during transmission rope 44 is stretched, and then
One drive 41 can drive the second drive 51 to rotate again, wind spring 54 is furled from one of them second drive 51 to other one
Individual second drive 51 and the elastic-restoring force of accumulation itself, on the other hand, friction are passed through during resistance wheel 33 is rotated
Friction effect produced by between disk 36 and the friction portion 324 of resistance shell fragment 32, enables curtain 16 stably to act, once will
Curtain 16 discharges the pulling force for bestowing underbeam 14 again after being fully deployed, and resistance wheel 33 at this time can pass through unidirectional ratchet 31 and list
Stopped operating to the bridle joint relation between fluted disc 35, consequently, it is possible to which transmission rope 44 can pass through the friction between resistance wheel 33
Resistance and between the elastic-restoring force of wind spring 54 present standing balance state, curtain 16 is maintained at deployed condition.
When curtain 16 to be folded, underbeam 14 is up promoted as shown in figure 5, exerting a force first, transmission rope 44 is become pine
The state of relaxation and reduce the frictional resistance between resistance wheel 33, the elastic-restoring force of wind spring 54 at this time can be with user
Thrust force 2 second drive 51 simultaneously to rotate backward, can drive the again during the second drive 51 is rotated
One drive 41 is rotated, and the first drive 41 is furled transmission rope 44, is discharged and apply again when curtain 16 is folded completely
The thrust of underbeam 14 is given, makes transmission rope 44 again tightly around in the elastic-restoring force and transmission rope of resistance wheel 33, at this time wind spring 54
The state of standing balance will be presented between frictional resistance between 44 and resistance wheel 33 once again, is maintained at curtain 16 and folds shape
State.
Herein it should be added that, the present invention can have different changes in structure, as shown in fig. 6, resistance wheel 63
Resistance wheel shaft 64 surround by two transmission ropes 44, separated out between two transmission ropes 44 by the frictional disk 65 of resistance wheel 63
Come, moreover, one end of two transmission ropes 44 is commonly connected to first drive 61, in addition, two the second drives 62 it
Between linked together by two panels wind spring 54, structure so configuration can coordinate large-sized curtain to use.
In summary, curtain detent mechanism 18 of the invention is mainly utilized produced by between transmission rope 44 and resistance wheel 33
Bridle joint relation between frictional resistance and unidirectional ratchet 31 and resistance wheel 33 and good locating effect is provided curtain 16, to have
Effect solves the problems, such as the rise of curtain after deployment and the sagging problem when folding and reaching increases the purpose of ease of use.
