One reel (20) is microscler cylindric, and the window that its axial length is about and institute's desire is used is horizontal wide isometric.Reel (20) (is annotated: usually at the affixed crossbearer of window apical margin in order to laterally to be hubbed at the window apical margin, again reel is articulated in this crossbearer), be available for users to control and original place rotation (notes: the method that control is rotated reel (20), pull rope mechanism for example can be set spur stay cord and drive reel (20), or motor drive mechanism is set to be rotated with line traffic control or remote control mode control reel (20) for the user for the user; But aforementioned manner is known skill and creates emphasis with the application and has nothing to do, so will not describe in detail).
One sheer pole (30) is parallel to reel (20) below, is that the flat of a hollow is rectangular, and its length is horizontal wide isometric with window approximately, and width is then made an appointment with and reel (20) equal diameters, for metal material (for example aluminium extruded type) omits tool weight.Two ends respectively are provided with an end cover (31) about sheer pole (30), see also Fig. 3, and each end cover (31) has one and embeds the inner caulked (32) of sheer pole (30) by end face, and a L shaped plate (33) that is linked to caulked (32) outer end.This L shaped plate (33) wherein end bending extends to sheer pole (30) bottom side, form a supporting plate (34) parallel with sheer pole (30) bottom surface, and L shaped plate (33) other end is perpendicular to sheer pole (30), and forms a side plate (35) that exceeds sheer pole (30) end face predetermined altitude.
Some blades (40), each is made with soft fabric, and area is long and narrow rectangle, and its length is horizontal wide isometric with window approximately, and width is slightly less than reel (20) diameter.The relative two long limits of each blade (40) are overseam one side rod (41) respectively, makes blade (40) can roughly keep the glacing flatness that major axis makes progress; Each blade (40) can upwards form crooked at minor axis conversely speaking.These blades (40) line is between reel (20) and sheer pole (30).
Two connection cord groups (50), be located at the right two end places of keeping left partially of these blades (40) symmetrically, a rope (51) and a back rope (52) before each connection cord group (50) comprises one, before rope (51) and back rope (52) extends longitudinally and front and back are relative, length all is substantially equal to the window lengthwise, the top is linked to relative two sides of reel (20) side face respectively, and the bottom is linked to front and back two lateral margins of sheer pole (30) respectively; In addition, before rope (51) and back rope (52) respectively with etc. between the mode leading edge and the trailing edge that connect these blades (40) one by one (annotate: in the present embodiment, preceding rope (51) and back rope (52) are the side rods (41) that is tied to blade (40) front and back dual side-edge, and this is to use skill always; Other still have multiple known juncture, hold and do not give unnecessary details).By vertical connection of this two connection cords group (50), sheer pole (30) and these blades (40) can be suspended to reel (20) below with predetermined relationship.See also Fig. 2, side by side, wherein, the spacing (P) of adjacent two blades (40) (that is preceding rope (51) or back rope (52) length between two blades (40)) was slightly less than the bond length (W) of blade (40) between these blades (40) were etc.In addition, present embodiment makes especially that the blade (40a) of below is close to sheer pole (30) end face.Moreover, lowermost two blades (40a) (40b), about two ends respectively by side plate (35) retaining of this two ends cover (31) of sheer pole (30) to, sliding partially about not understanding.
One cloth sheet (60), material is the class of tulle, has the light transmission of appropriateness.The area of cloth sheet (60) is rectangular, and its length is about the twice of window lengthwise, and width is then about horizontal wide isometric with window.This cloth sheet (60) according to major axis to rough half area (being the area of corresponding window size) position of half-and-half distinguishing in these blades (40) the place ahead, the rough central part of cloth sheet (60) is walked around this sheer pole (30) bottom side, should be curved about partly two sides between sheer pole (30) and this two supporting plate (34) (as shown in Figure 3), other rough half area of cloth sheet (60) then the position at these blades (40) rear, simultaneously, the apical margin of cloth sheet (60) front and back two halves is linked to relative two sides of reel (20) side face respectively.In addition, the length of the length of cloth sheet (60) and connection cord group (50) cooperatively interacts, make sheer pole (30) can keep being pressed on cloth sheet (60) lowermost end (that is cloth sheet (60) central authorities are curved around inner face partly), two sides all can longitudinally smooth extension before and after the cloth sheet (60) and allow.And can be pressed on cloth sheet (60) bottom in order to ensure sheer pole (30), can allow connection cord group (50) a little long a little on making, so, the bottom of each connection cord group (50) partly have can't full extension phenomenon, be shown in Fig. 2, before rope (51) and back rope (52) blade (40a) and the rope body between second from the bottom blade (40b) below, promptly can't be straightened fully as other parts.
More than be the formation of the roller shutter (10) of the utility model one preferred embodiment.
When just changeing (referring to the clockwise rotation among Fig. 2) or reverse when user's control makes reel (20), can be with this cloth sheet (60), this two connection cords group (50) and these blades (40), little by little up draw and carry and furl to reel (20) side face, or little by little down put lowering to good use by reel (20) side face by reel (20) rear side.When sheer pole (30) hangs down when reducing as far as possible, these blades (40) promptly are evenly distributed in whole fan window; Can see through connection cord group (50) drive these blades (40) synchronous change blade face angle, to be adjusted to required printing opacity and shield coverage if control makes reel (20) deflection this moment; Above function is same as roller shutter commonly used.In the utility model, especially cover front and back two sides of these blades (40) simultaneously as this cloth sheet (60) of doubling, and cloth sheet (60) is curved is down exerted pressure by sheer pole (30) around locating, therefore can respectively form the smooth cloth curtain of an appropriate printing opacity in two sides before and after the blade (40), its visual effect is identical with roller shutter commonly used.
When reel (20) begins just changeing under roller shutter full extension state (for example will adjust blade tilt or will up furl), as shown in Figure 4, cloth sheet (60) the position apical margin in the front side engages partly and can be reduced to reel (20) bottom side earlier, cloth sheet (60) position the apical margin of rear side partly then can along the work rotation direction early one step ahead coating to reel (20) side face; And then when reel (20) continued just to change, as shown in Figure 5, the front and back two halves of cloth sheet (60) and these blades (40) can be wound to the reel side face by reel (20) rear side in the lump gradually.The said structure that provides by the utility model, even if two halves are wound to the starting point and the coiling speed and inconsistent of reel (20) side face before and after the cloth sheet (60), but because of cloth sheet (60) does not link with these blades (40) or sheer pole (30), therefore the central authorities of cloth sheet (60) are curved can slide before and after sheer pole (20) bottom side around the position, the cloth cover length of distributing as two sides before and after the automatic adjusting, make the cloth cover of two sides can keep smooth pulling-over state at any time, the bottom of unlikely generation roller shutter commonly used has more the situation not attractive in appearance that one section fold is hung down and weighed down.
What must remark additionally is, before take off embodiment sheer pole (30) two ends be provided with supporting plate (34) be trapped among cloth sheet (60) curved about locating two sides, and side plate (35) retaining is set at (40b) two ends of blade (40a), all are smooth and easy and neat when keeping action.
Moreover, width of blade (W) is than the bigger predetermined length of blade pitgh (P), purpose is when making these blades (40) upright, the apical margin of lower leaflet (previous trailing edge) side rod (41), can be a little more than root edge (previous leading edge) side rod (41) of top blade, as shown in Figure 5, avoid the folded mutually facts of side rod in the roller shutter commonly used, making can be comparatively evenly neat when blade (40) is wound to reel (20) side face.And, establish a blade (40) at sheer pole (30) end face, can make outward appearance more consistent and attractive in appearance.
In addition, cloth sheet in the utility model does not limit will walk around the sheer pole bottom surface, for example also can establish grow crosswise the hole seam (almost isometric with sheer pole) and front and back two sides of this hole seam break-through sheer pole at sheer pole, so for the cloth sheet with can before and after the mode of slippage pass, can reach above-mentioned functions equally.
