Embodiment

Please referring initially to Fig. 1, the curtain without stretching wire 10 shown in figure includes the underbeam of the relative upper beam 12 of a upper beam 12, one 14, and a curtain 16 being located between upper and lower beam 12,14.Referring again to Fig. 2 and Fig. 3, curtain detent mechanism 18 of the invention Include a transmission device 20 and a damping unit 30.

Transmission device 20 has a fixed seat 21,2 first drives 22, a wind spring 23,2 second drives 24, and Two pairs of transmission ropes 25, wherein：

There are each first drive 22 2 first transmission fluted discs 221 (as long as actually at least one) to be connected to one The first power axle 223 between the 2 first transmissions fluted disc 221, is sheathed on upper and lower in assembling by the first power axle 223 Wherein two upper and lower fixing axles 216,218 of fixed plate 212,214, after assembly is completed, the of 2 first drive 22 The one mutual bridle joint of the transmission meeting of fluted disc 221 is together.

Wind spring 23 connects the first power axle 223 of 2 first drive 22 so that wind spring 23 can be by 2 first biography The relative rotation of driving wheel 22 and the first power axle 223 for being wound in one of them the first drive 22.

There are each second drive 24 2 second transmission fluted discs 242 and one to be connected between the 2 second transmissions fluted disc 242 The second power axle 244, other two of upper and lower fixing plate 212,214 are sheathed on by the second power axle 244 in assembling Upper and lower fixing axle 216,218, after assembly is completed, the second transmission fluted disc 242 of 2 second drive 24 can distinguish bridle joint First in the first drive 22 is driven fluted disc 221 so that first, second drive 22,24 can synchronous axial system.

The second power axle 244 of the second drive 24, every a pair of transmission ropes are fixed in one end of every a pair of transmission ropes 25 25 other end passes curtain 16 and is fixed on upper beam 12.The mistake rotated in order to avoid two transmission ropes 25 in the second drive 24 Wound mutually in journey, the center of the second power axle 244 of the second drive 24 can set a separation ring portion 246 by two biographies Running rope 25 is separated.

Referring again to Fig. 3, damping unit 30 has a shaft seat 40, a damper 50, and a rotating shaft 60, wherein：

Shaft seat 40 is fixed in underbeam 14 and the two sides wall 41,42 is connected with one with two relative side walls 41,42 Bottom wall 43, one of side wall 41 has a pivot connected slot 44, and another side wall 42 has a caulking groove 45.

Damper 50 has a fuel reserve tank 52 and a spragging gear 54, and fuel reserve tank 52 is fixed on the caulking groove 45 of shaft seat 40 Interior, to store the damping oil with high viscosity characteristic, spragging gear 54 is hubbed at fuel reserve tank 52 and positioned at the embedding of shaft seat 40 Outside groove 45.

One end of rotating shaft 60 is pivotly connected in the pivot connected slot 44 of shaft seat 40, and the other end of rotating shaft 60 has a tooth Shape covers hole 62 so that rotating shaft 60 can be covered the spragging gear 54 that hole 62 is connected in damper 50 by dentation, be after assembly is completed Can be with the synchronous axial system of spragging gear 54.In addition, rotating shaft 60 is surround by one pair of which transmission rope 25, in order to avoid two transmission ropes 25 wind mutually during rotating shaft 60 is rotated, and the center of rotating shaft 60 can set a Spacing flanges 64 by two transmission ropes 25 Separate.

From said structure, when curtain 16 to be deployed, exert a force the pulled down of underbeam 14 first, make each transmission rope 25 Moving and be stretched with underbeam 14, during transmission rope 25 is stretched, on the one hand can drive 24 turns of the second drive It is dynamic, make the second drive 24 drive the first drive 22 to rotate again, wind spring 23 at this time can be from one of them the first drive 22 retractings are to the elastic-restoring force of another first drive 22 and accumulation itself, and on the other hand, transmission rope 25 can drive again Rotating shaft 60 is rotated, and makes rotating shaft 60 drive spragging gear 54 to rotate, and release is to underbeam 14 after curtain 16 is fully deployed Pulling force, damping oil countershaft 60 of the meeting of spragging gear 54 stored by fuel reserve tank 52 now bestows stream resistance hysteresis, and this is first-class Resistance hysteresis can between the elastic-restoring force of wind spring 23 present standing balance state, consequently, it is possible to transmission rope 25 will be unable to by Second drive 24 furls and allows curtain 16 to be maintained at deployed condition as shown in Figure 1 really.

When curtain 16 to be folded, exert a force up promote underbeam 14 first, now as shown in figure 5, the elasticity of wind spring 23 Restoring force is just enough to overcome damping oil stored in fuel reserve tank 52 to pass through the countershaft of spragging gear 54 by the thrust of user The 60 stream resistance hysteresis bestowed, the first drive 22 meeting at this time is simultaneously to rotate backward, and the band during rotation Dynamic second drive 24 rotates and transmission rope 25 is furled, and is discharged again after curtain 16 is folded completely and bestows underbeam 14 Thrust, standing balance can be presented once again between the stream resistance hysteresis that at this time elastic-restoring force and damping oil of wind spring 23 are provided State, curtain 16 is maintained at collapse state as shown in Figure 6.

In summary, the stream resistance hysteresis that curtain detent mechanism 18 of the invention is provided using damper 50 is carried to curtain 16 For good locating effect, reached with effectively solving the problems, such as the rise of curtain 16 after deployment and the sagging problem when folding Increase the purpose of ease of use.
