Description

Sun blind

Technical field

The utility model relates to sun blind, particularly relates to a kind of simple in structurely, can reduce the sun blind of manufacturing cost.

Background technology

See also traditional sun blind 10 of Fig. 1, its consist predominantly of one put the beams in place 11, two be located at ladder that 11 the fixators 12, two of putting the beams in place connect these these fixators 12 respectively with 13, these these ladders of a plurality of connection are located at the driving iron bar 17 that put the beams in place 11 driver 15, a stay cord 16 and that connects driver 15 are arranged in these these fixators 12 and driver 15 with 13 blade 14.

Please cooperate and consult Figure 1A, when the user spurs stay cord 16 downwards, the internal gear that drives driver 15 is rotated, simultaneously, the internal gear of driver 15 will drive fixator 12 rotations by driving iron bar 17, fixator 12 will be with 13 to drive blade 14 deflections by these these ladders again, to reach the effect of adjusting light.

Hence one can see that, traditional sun blind 10 are if will obtain to adjust the effect of light, the start that must pass through a plurality of members such as driver 15, driving iron bar 17 and fixator 12 could drive blade 14 deflections, and it is quite complicated that whole structure seems, manufacturing cost also will improve certainly thereupon.

The utility model content

Main purpose of the present utility model is to provide a kind of sun blind, and it is simple in structure, can effectively reduce manufacturing cost.

For reaching above-mentioned purpose, sun blind provided by the utility model include a upper beam, a plurality of blade, two ladder bands and two stay cords.These these ladder band is located at this upper beam with its top respectively, and connects the respectively two opposite sides of this blade; These these stay cords are fixed in this upper beam with its top respectively and can drive this upper beam rotation respectively.

When spurring wherein stay cord, will drive this upper beam towards rotation clockwise, make these these terraced band can drive this these blade deflections, to reach the effect of light modulation by the rotation of this upper beam; When the other stay cord of pulling, will drive this upper beam towards the counterclockwise rotation, make these these blades be returned to state originally.

The beneficial effects of the utility model: via as can be known above-mentioned, the utility model dispenses employed driver in the prior art sun blind, fixator and driving iron bar, and be to use two stay cords and a rotating upper beam to control blade deflection, to reach the purpose of light modulation, sun blind of the present utility model are had than the more simple structure of prior art sun blind, and manufacturing cost also just can be lowered certainly effectively.

The specific embodiment

In order to describe structure of the present utility model, feature and effect place in detail, lift now the explanation of following preferred embodiment and conjunction with figs. as after.

See also Fig. 2 and Fig. 4, be the sun blind 20 that the utility model one preferred embodiment is provided, include put the beams in place 30, one underbeam 40, a plurality of blade 50, four ladders and be with 52, one lifting stay cord, 60, one left big envelope 70, one right big envelope 80, one first light modulation stay cord 90 and one second light modulation stay cord 92.

Please cooperate and consult Fig. 2 and Fig. 3, the cross sectional shape of upper beam 30 is circular in the present embodiment, but is not limited to circle.Upper beam 30 has a left part 32 and a

right part

34,30 outer peripheral faces in left part 32 of wherein putting the beams in place are formed with the left groove 326 of 2 first grooves 322,324 and between this these first groove 322,324, and 34 outer peripheral face forms a right groove 342 in the right part.

The cross section of underbeam 40 is a rectangle, is positioned at the below of upper beam 30.

These these blades 50 equally spaced are arranged between upper beam 30 and the underbeam 40.

These these ladders are in pairs settings with 52.Each is fixed in 52 top ladder puts the beams in place 30, and drawdown and connect the two opposite sides of each blade 50 downwards, is fixed in underbeam 40 with its bottom again.

The top of lifting stay cord 60 stretch into put the beams in place in 30 and with not shown in the figures connection of a pulley gear of 30 inside of putting the beams in place, the bottom is drawdown downwards then.By pulling lifting stay cord 60, can these these blades 50 be folded by pulley gear, as shown in Figure 6.

Please cooperate and consult Fig. 3, left side big envelope 70 has a left big envelope seat 72 and a left big envelope lid 74, wherein left big envelope seat 72 can be fixed in wall or window frame, and the inner peripheral surface of left big envelope lid 74 has the left raised line 746 of 2 second grooves 742,744 and between this these second groove 742,744.When left big envelope lid 74 is covered on when putting the beams in place 30 left part 32, left raised line 746 is sticked in 30 the left groove 326 of putting the beams in place, and this these first groove 322,324 of this these second groove 742,744 of left big envelope lid 74 and upper beam 30 is relative in twos.In addition, left big envelope lid 74 has one first perforation, 76 and 1 second perforation 78.

Right big envelope 80 has the right big envelope seat 82 and a right big envelope that can be fixed in wall or window frame equally and covers 84, and the inner peripheral surface of right big envelope lid 84 has a right raised line 842.When right big envelope lid 84 was covered on the right part 34 of upper beam 30, right raised line 842 was sticked in the right groove 342 of upper beam 30.

The top of the first light modulation stay cord 90 is fixed in the left part 32 of upper beam 30, and along first groove 322 and the left big envelope of the left part 32 of pile warp upper beam 30 cover 74 second groove 742 clockwise, pass first perforation 76 of left big envelope lid 74 again and drawdown downwards, make and win light modulation stay cord 90 when pulled, can drive and put the beams in place 30 towards rotating clockwise.

The top of the second light modulation stay cord 92 is fixed in the left part 32 of upper beam 30 equally, and along counterclockwise pile warp put the beams in place first groove 324 of 30 left part 32 and second groove 744 of left big envelope lid 74, pass second perforation 78 of left big envelope lid 74 again and drawdown downwards, make the second light modulation stay cord 92 when pulled, can drive puts the beams in place 30 rotates towards counterclockwise.

When the downward pulling first light modulation stay cord 90, will drive and put the beams in place 30 towards rotation clockwise, make these these ladders can drive this these blade 50 deflections by 30 the rotation of putting the beams in place, as shown in Figure 5 with 52; After 30 rotations of putting the beams in place, by the frictional force between the left groove 326 of left raised line 746 and left big envelope 70, and right raised line 842 locatees with the frictional force of the right groove 342 of right big envelope 80, in order to these these blades 50 are remained on the state after the deflection, so that the effect of light modulation to be provided.

In the time these these blades 50 will being reverted back to the state of printing opacity, then be that the pulling second light modulation stay cord 92 forces to put the beams in place and 30 rotates towards counterclockwise, these these ladders also go back to position originally with regard to driving these these blade 50 deflections again via the rotation of upper beam 30 with 52, as shown in Figure 4.

In addition, when wanting these these blades 50 of folding and unfolding, be that the pulley gear that utilizes pulling lifting stay cord 60 to drive 30 inside of putting the beams in place carries out folding and unfolding with these these blades 50, as shown in Figure 6.Since the folding and unfolding blade do flowing mode and traditional shutter to make flowing mode identical, this just appearance do not give unnecessary details detailed process.

The utility model related composed component in previous embodiment only for illustrating, is not to be used for limiting scope of the present utility model, and substituting or changing of other equivalence element also should be claim of the present utility model and contain.
