Specific embodiment
Please referring initially to Fig. 1 and Fig. 6, curtain arrestment mechanism 20 of the invention is mainly used with unification curtain without stretching wire 10, figure
Shown in curtain without stretching wire 10 include a upper beam 12, a underbeam 14 and one be set to curtain between upper and lower beam 12,14
16.Referring again to Fig. 2 and Fig. 3, curtain arrestment mechanism 20 of the invention includes that a pedestal 30, one retracting unit 40, two is driven
Unit 50 and two one-way clutch units 60.
Pedestal 30 is installed in upper beam 12 and butts up against the bottom plate 34 of top plate 32 with a top plate 32 and one, wherein in top plate
32 have two opposite perforation 36, are worn with for a turning-bar 18 of curtain without stretching wire 10.
Furling unit 40, there is wind spring wheel 41, two on two to descend wind spring 43 on wind spring wheel 42, one, and wind spring 44 once.It should
On two wind spring wheel 41 by left and right side by side in a manner of be set to pedestal 30 top plate 32 and mutually bridle joint together, the two lower wind spring wheels 42
The bottom plate 34 of pedestal 30 and mutual bridle joint are set in a manner of controlling side by side together, in addition, between upper and lower wind spring wheel 41,42
It links together by a connecting shaft 45, upper and lower wind spring wheel 41,42 is rotated synchronously;The both ends of upper wind spring 43 connect respectively
A upper wind spring wheel 41 is connect, wind spring 43 is wound on one of them by the relative rotation of two upper wind spring wheels 41
Wind spring wheel 41, the both ends of lower wind spring 44 are separately connected a lower wind spring wheel 42, enable lower wind spring 44 by two lower wind spring wheels
42 relative rotation and be wound in wind spring wheel 42 under one of them.
Each gear unit 50 has a bull wheel 52 and two drawstrings 54.Bull wheel 52 is rotatably arranged in pedestal 30
Between top, bottom plate 32,34 and bridle joint is in a lower wind spring wheel 42, enables bull wheel 52 with the lower wind spring wheel 42 with its phase bridle joint
It rotates synchronously;The both ends of each drawstring 54 are individually fixed in underbeam 14 and bull wheel 52, so that on the one hand two drawstrings 54 can
Bull wheel 52 (as shown in Figure 7) is wound in mode side by side up and down by the drive of bull wheel 52, and in winding process
It drives underbeam 14 to rise, on the other hand can release (as shown in Figure 6) from bull wheel 52 by the pulling of underbeam 14, and
Bull wheel 52 is driven to rotate during release.
One-way clutch unit 60 is adjacent to bull wheel 52 and has a wheel shaft 61, three brake block 62, an one-way wheel 63, and
Three planetary gears 64, in which:
The both ends of wheel shaft 61 are individually fixed in the top of pedestal 20, bottom plate 32,34.
Brake block 62 is fixed on the bottom plate 24 of pedestal 20 and the mode that equiangularly arranges is connected to the outer peripheral edge of wheel shaft 61,
So that an arc rolling groove 65 is formed between two neighboring brake block 62, then as shown in Figures 4 and 5,65 one end of arc rolling groove
Curvature be greater than the curvature of 65 other end of arc rolling groove, what is abutted by the both ends of each arc rolling groove 65 is different
Brake block 62, so the both ends of each brake block 62 can be respectively formed with the curvature difference at 65 both ends of arc rolling groove
One braking parts 66 and a carrier 67, as shown in Figures 4 and 5, the curvature of braking parts 66 are greater than the curvature of carrier 67.
There is one-way wheel 63 axis hole 68 and one to be adjacent to the inner ring teeth portion 69 of axis hole 68, as shown in Figures 3 and 4, unidirectionally
Wheel 63 is sheathed on wheel shaft 61 by axis hole 68, and one-way wheel 63 can allow inner ring teeth portion 69 to be surrounded on braking after being sheathed on wheel shaft 61
Around block 62.In addition, one-way wheel 63 is enclosed in mode side by side up and down around one by two drawstrings 54, so that two 54 quilts of drawstring
Underbeam 14 can drive one-way wheel 63 to rotate simultaneously during pulling.
Planetary gear 64 is set in rolling groove 65 and bridle joint is in the inner ring teeth portion 69 of one-way wheel 63, enables planetary gear 64
It is driven in the rotation process of one-way wheel 63 by the inner ring teeth portion 69 of one-way wheel 63 and is rolled along rolling groove 65.
By above structure it is found that when curtain 18 to be unfolded, as shown in fig. 6, force makes 14 pulled down of underbeam first
Drawstring 54 is stretched by underbeam 14, and one-way wheel 63 and bull wheel 52 can first be driven to start to turn during drawstring 54 is stretched
It is dynamic, during one-way wheel 63 rotates, as shown in figure 4, one-way wheel 63 by inner ring teeth portion 69 drive planetary gear 64 along
Rolling groove 65 is rolled to the carrier 67 of brake block 62, and idling conditions can be presented in planetary gear 64 at this time, so that one-way wheel
63 can be pulled by drawstring 54 and are freely rotated, and on the other hand, will drive and its phase bridle joint during bull wheel 52 rotates
Under wind spring wheel 42 rotate, lower wind spring 44 rotation during wind spring wheel 41 on coupled can be driven to turn together again
It is dynamic, whereby, upper wind spring 40 can from the 6th figure on the left side retracting of wind spring wheel 41 into the 6th figure on the right wind spring wheel 41 and store
The elastic-restoring force of product itself, lower wind spring 44 also can be from wind spring wheel 42 is furled into the 6th figure under the right under the left side in the 6th figure
Wind spring wheel 42 and the elastic-restoring force for accumulating itself.
Once curtain 16 is expanded to and discharges the pulling force for bestowing underbeam 14 after appropriate location again, upper and lower wind spring at this time
Wheel 41,42 can be driven bull wheel 52 to generate by the elastic-restoring force of upper and lower wind spring 43,44 by lower wind spring wheel 42 respectively
Micro- rotates backward, and the drawstring 54 of sub-fraction can be then wound during bull wheel 52 rotates backward, makes one-way wheel 63
It can be pulled by drawstring 54 and generate rotating backward slightly, it can be by inner ring teeth portion 69 during one-way wheel 63 rotates backward
It drives planetary gear 64 to roll along rolling groove 65 to the braking parts 66 of brake block 62 and forms clamping, as shown in figure 5, such one
Coming, planetary gear 64 can stop operating immediately, and related one-way wheel 63 can be allowed to stop operating after planetary gear 64 stops operating,
At this time drawstring 54 can be by the frictional resistance between one-way wheel 63 and between the elastic-restoring force of upper and lower wind spring 43,44
The state that standing balance is presented, is able to maintain curtain 16 in unfolded state.
When curtain 16 to be folded, as shown in fig. 7, force up pushes underbeam 14 first, drawstring 54 is made to become loose
State and reduce the frictional resistance between one-way wheel 63, make the elastic-restoring force of upper and lower wind spring 43,44 by user's
Thrust forces upper and lower wind spring wheel 41,42 while to rotate backward, and can drive drawing again during lower wind spring wheel 42 rotates backward
Rope sheave 52 rotates, and furls bull wheel 52 to drawstring 54, discharges again when curtain 16 folds completely and bestow underbeam 14
Thrust makes drawstring 54 again tightly around in one-way wheel 63, and curtain 16 at this time is located in collapse state as shown in Figure 8, unidirectionally
Wheel 63 is all held in the state not rotated during curtain 16 folds.
To sum up institute is old, and it is good fixed that curtain arrestment mechanism 20 of the invention provides curtain 16 using one-way clutch unit 60
Position effect generally has the configuration of simple structure, and operational stability is also very good, thus can effectively solve curtain
The rise problem of body 16 after deployment and the sagging problem when folding and achieve the purpose that increase operation ease, especially can be with
It is useful in large-sized curtain without stretching wire 10.
