Description
Technical field
The utility model relates to a kind of sun blind, is meant the jack of the louver lamina of two kinds of terraced interband distances of a kind of employing especially.
Background technology
Traditional sun blind mostly are wooden, make meticulous wooden sun blind and have shown nature, graceful and luxurious; It is a plastic material to the development-oriented of citizenization, inexpensive and thing U.S..The metal that the structure of these conventional junction configuration sun blind generally comprises iron or aluminium matter is put the beams in place or the PVC of plastic material puts the beams in place and supporting holder, fixator, OM, iron bar, wooden or plastics matter blade, go up rail, transfer rod, stay cord and stay cord lockset, down rail, ladder band, buckle etc. down, also be provided with the outer shrouding of decorating in order to block operative components, and need in the middle of putting the beams in place, to be provided with L type carriage when installing, could whole sun blind are fixing steadily on the wall.Chinese patent ZL01232351.9 " horizontal type louver curtain " provides an illustration for aforementioned structure, the structure that this patent proposes for one horizontally disposed go up rail, be positioned at following rail that the rail below is used to provide counterweight, be positioned at about blade, two between rail be used to sling down rail and pass the stay cord of blade, and be used to control the guiding mechanism of blade angle.In this class formation, the upper end of ladder band is fixed on the rail upper and lower end and is fixed on down on the rail, passing stay cord hole and its lower end that the stay cord that is fixed on the lockset in the rail must pass on the blade is fixed on down on the rail, blade is evenly distributed between the upper and lower rail and is sleeved in the ladder band, and the variation that is reached direction by the ladder band up and down drives blade change direction and folding and unfolding.At this moment, because the density of blade immobilizes, though can realize good screening effect, then the resistance light action of blade is also big when the good printing opacity of needs.
The utility model content
Problem to be solved in the utility model be by which kind of structure and improve imagination provide a kind of not only had good screening effect but also have good light permeability can the novel window blind curtain.
Designed a kind of jack of louver lamina according to above-mentioned problem to be solved, comprise rail, following rail and blade, on last rail, be provided with blade angle adjusting device and transfer rod thereof and folding and unfolding stay cord and locking device thereof, with supporting ladder band and the fixator of folding and unfolding stay cord, traditional common devices such as OM, have the hole of passing for the folding and unfolding stay cord at the left and right sides of blade close end, the stay cord lower end is fixed on down on the rail, blade is positioned at, also overlap between the following rail and be through in the ladder band, have two pairs at this ladder, one pair is traditional, the little spacing ladder band of each sheet blade one lattice, another pair is the big spacing ladder band of two or three or multi-disc blade one lattice, the two secondary ladder bands that are somebody's turn to do respectively have a supporting folding and unfolding stay cord and a locking device thereof, and employed locking device both can be the double bolt lockset, also can be single latch lockset, decide as required.
Wherein, big spacing ladder band folding and unfolding stay cord and locking device thereof and little spacing ladder band folding and unfolding stay cord and locking device thereof are separated, two holes of passing for the folding and unfolding stay cord are side by side promptly arranged, and every the spacing of setting the one support iron ring that is installed in below the blade is set on the big spacing ladder band folding and unfolding stay cord.
The utility model is two big spacing ladder bands about increase on the basis of traditional sun blind has designed, and on last rail, set up a latch lockset, therefore when spurring the stay cord of big spacing ladder band, can close the blade of setting the sheet number several be one, so both suitable screening effect can be arranged, realized better printing opacity again, on visual effect as if the number of blade of sun blind reduce by half or subtract three/second-class, give the people a kind of light sense.
Description of drawings
Accompanying drawing 1 is the structural behavior schematic perspective view after the utility model assembling; Accompanying drawing 2 is the big spacing ladder of the utility model band and interlobate structure partial enlarged diagram.
The specific embodiment
The utility model is for the light transmittance that increases traditional sun blind and does not influence screening effect and an improvement project proposing.
With reference to accompanying drawing.The utility model is similar with traditional face leaf curtain on overall structure, comprise rail 1 on the matrix, in the groove of last rail, generally install, be provided with ohm 2, fixator 3, holder 4 from left to right respectively, and ohm, fixator and holder are all by iron bar 5 location and fixing; Simultaneously, transfer rod 14 generally is installed in the left side of rail, and stay cord and supporting lockset thereof are arranged on the right side; Be equipped with down on following rail 11 and detaining, and be connected with ladder band and the realization of last rail by stay cord, 10 in blade is installed in ladder by traditional mode and is with in the lattice.
Inventive point of the present utility model is to be provided with two parbuckles 6,7 and supporting lockset 8,9 thereof in last rail, promptly traditional, the little spacing ladder that is inserted in the ladder band lattice of blade is with 12 one by one, and big spacing ladder is with 13.Wherein, the length of big spacing ladder band lattice is the twice or the integral multiple of little spacing ladder band, and supporting lockset can adopt traditional double bolt or single latch lockset, and also two kinds of locksets are used with as required.What need further specify at this is big spacing ladder band and interlobate annexation, at first big spacing ladder band folding and unfolding stay cord and locking device thereof are separated with little spacing ladder band folding and unfolding stay cord and locking device thereof, so two secondary folding and unfolding stay cords just can not produce interference each other when operation, but in order to operate the convenience with process and assemble, two secondary stay cords and supporting component design side by side, promptly on blade, have two holes 16 that supply the folding and unfolding stay cord to pass side by side, reach double bolt or single latch lockset with the stay cord coupling; Secondly little spacing ladder band is a traditional structure with structural relation between the folding and unfolding stay cord fully, but as two or threeleaf loosestrife herb sheet the one support iron ring 15 that is installed in below the blade is set every the spacing of setting on the big spacing ladder band folding and unfolding stay cord.The optimum shape of described iron ring is that 8 fonts also are the dicyclo type, the folding and unfolding stay cord that one of them ring is with for big spacing ladder passes and fixedlys connected with stay cord, another folding and unfolding stay cord that encircles for little spacing ladder band passes, and effect is to make the interlobate spacing stack facility more of striding.Certainly iron ring also can be designed to individual pen shape or other shape as required.
During use, after then two secondary stay cords being decontroled fully as the need shield lights, utilize transfer rod to adjust blade angle shutter is closed; As the suitable printing opacity of need, then except that the adjustable blade angle, also can spur the stay cord of big spacing ladder band, two or multi-disc blade are overlaped.Therefore, multiple mode of operation and suitable selection are provided to the user.
