Abstract

The utility model relates to a control structure for blades of a window blind. A first ladder cord is arranged between a top beam and a bottom beam of the window blink, each blade is pivoted, abutted and positioned on the first ladder cord at equal intervals, the blades are wound and positioned on regulating seats in the top beam, and both sides of each regulating seat are provided with regulating wheels. A piece of pull rope is pivoted with a rope penetrating hole of each blade and is downwards wound from a pulley seat on one side in the top beam. Positioning seats, linking pull sheets which are linked with each other, and sliding guiding members are arranged between the regulating seats in the top beam and are respectively wound and connected with a second ladder cord and an operating rope. The operating rope vertically and downwards extends along a pulley seat on other side of the bottom beam; the second ladder cord straddles the bottom beam in a U shape; the positioning sections of the second ladder cord straddle the blades of odd number (or even number) at intervals. With the structure, the second ladder cord is linked to move upwards by pulling the operating rope so that the operation is simple and quick, and the optimum user state can be obtained.

Description

The blade of louver window control structure

Technical field

The utility model is relevant for a kind of blade of louver window control structure.

Background technology

Below enumerating the patent of invention that the U.S. checks and approves demonstrate,proves US664804B2 number, be illustrated in figure 1 as known plan view, its shutter 10 is respectively equipped with the first ladder rope, the 11 and second ladder rope 12 and is mounted on each blade 13 in regular turn, and be the ㄩ shape and be around underbeam 14, and 15 the both sides of putting the beams in place are respectively equipped with location traveller 151 and first, second pulley base 152,153 for the first ladder rope, the 11 and second ladder rope, 12 two ends wear around and descend, when first ladder restricts 11 when pulled, 13 in blade can present also folded in twos and make the printing opacity space increase (being illustrated in figure 2 as known user mode figure), and work as the second ladder rope 12 when pulled, then blade 13 is continued up to fold, and 15 the inside group of putting the beams in place is established holder that a tool adjusts body and is made blade 13 can do the turn of angle (graphic being drawn) for the ladder rope location that bridges.

Aforesaid known structure, it still has following disappearance: (one) first ladder the rope 11 and second ladder rope 12 is to be descended by the same side drawdown of upper beam 15, so on using, often must operate again because of the mistake on judging, and in case the two ends of the first ladder rope, the 11 or second ladder rope 12 because of the power of pulling not for the moment, then can make blade 13 produce the situation of inclination, cause comparatively inconvenience in the use; (2) first ladder ropes 11 are around underbeam 14, thus in case the power of pullling when excessive, then can drive underbeam 14 rises and make each blade 13 up fold shape in regular turn in an overlapping, and can't present really also stacked in twos, so more wayward on operating; (3) first of the shutter 10 ladder rope 11 is around the inside of underbeam 14, so in operation, then must spur underbeam 14 earlier and can make the first ladder rope 11 smoothly through 152 stretchings of first pulley base and descend, causes the power that comparatively consumes in the operation.

Summary of the invention

Main purpose of the present utility model, be to provide a kind of blade of louver window control structure, its shutter utilizes slide guide part and interlock pulling-on piece and the second ladder rope to produce interlock and be subjected to a stand alone type to operate the design of rope control, impel in the operation, only must the pull operation rope can make the up start of synchronously second ladder being restricted of slide guide part, can be because of the unequal situation that causes blade lean of power, and utilize stay cord and operation rope to be mounted on the design of upper beam both sides respectively, do not have the situation that the customer must operate again because of misjudgment, to reach best user mode.

Secondary objective of the present utility model is to provide a kind of blade of louver window control structure, and shutter only must the pull operation rope, promptly can spur interlock pulling-on piece and slide guide part synchronously and affect the second terraced rope band moving vane up to be in twos and folded, and is more laborsaving in the order operation.

The purpose of this utility model is to realize like this, a kind of blade of louver window control structure, its shutter is in last, group is established the first ladder rope and is worn against the location for the equidistant pivot of each blade and wear around the location between underbeam, respectively be provided with the adjustment seat of tool adjusting lever in the inner both sides of putting the beams in place, make blade can do the rotation of different angles, and establish a stay cord pivot be through at each blade lacing hole and by the pulley base of the inner side of putting the beams in place wear around and descend, make blade fold and to launch with the do action of stay cord, the inner group between the adjustment seat of putting the beams in place established a positioning seat, organize respectively in the both sides of positioning seat and to establish a slide guide part, and set firmly an interlock pulling-on piece in the upper end of slide guide part and be subjected to an operation rope control, and be provided with the second ladder rope and wear around being consolidated in the slide guide part and stride the underbeam of being located at shutter, the rank, location of this second ladder rope are established and are the blade that is across odd number or even number at interval, and the operation rope is worn and is descended by the pulley base drawdown of upper beam opposite side by inside one side of putting the beams in place, and then only must the pull operation rope can make the interlock pulling-on piece drive each slide guide part synchronously and blade is in twos and folded the up start of restricting of second ladder, unexpected because of the unequal situation that causes blade lean of power, and utilize stay cord and operation rope to be mounted on the design of upper beam both sides respectively, the situation that it is unexpected that the customer must operate again because of misjudgment is to reach best user mode.

The inside of positioning seat is established one and is offered the opening-like guide channel of a side from top to bottom, is arranged with a hub setting groove in another routine wall of guide channel, and bottom land one side is cut in hub setting groove below and established a rectangular-shaped hole of engraving and form a guide plate, in engraving hole book office pivot group one slide bar.

The place upwards is convexly equipped with the abaculus that a tool colludes the angle in the middle of the slide guide part, and bilateral symmetry is convexly equipped with a card knot post and is arranged with a branch of groove, vertically is convexly equipped with the pivot post of a tool guide hole in the below of abaculus symmetry.

The interlock pulling-on piece provides embedded hole arranged side by side and some jacks in both sides circumferential surface book office, and provides a location pulling eye in book office.

The interlock pulling-on piece can be made as flexible plates.

Positioning seat is convexly equipped with assembly hole that some clamping blocks and the upper beam inside of shutter provided card group location mutually in the below of guide plate.
