Description

A kind of improved horizontal type louver

The utility model relates to a kind of improved horizontal type louver (Venetian blind), more particularly, relates to a kind of improved trapezoidal ribbon (ladder string) that is used for the adjusting vane angle.

Traditional horizontal type louver (Venetian blind) has functions such as sunshade, adjusting light and decoration and is widely used because of it.The concrete structure of tradition horizontal type louver as shown in Figure 1, it mainly includes rail 10 on, the once vane group 30 that is made of the multi-disc blade of rail 20,, the blade draw off gear 40 that a cover includes the stay cord 41 that can move up and down, and a cover includes the blade steering device 50 of many trapezoidal ribbons (ladder string) 51.For rail under the Balance Control 20 and vane group 30 are carried out folding and unfolding campaign up and down synchronously, thereby stay cord 41 is symmetrical set.The quantity of trapezoidal ribbon 51 is also along with the width of shutter is properly set simultaneously.

When using this traditional horizontal type louver, at first will go up rail 10 and be fixed on upper limb 61 places near door and window framework 60, utilize stay cord 41 to do synchronously folding and unfolding up and down and move and control down rail 20 and vane group 30 and put down and launch from last rail 10 is parallel.As shown in Figure 2, when rail 20 and vane group 30 are by parallel root edge 62 places of transferring to window 60 instantly, the blade of vane group 30 is all launched, and the blade that launches utilizes trapezoidal ribbon (ladder string) 51 to regulate, control whole blade group 30 can carry out parallel deflection in 180 degree, thereby reaches dimming function by blade steering.As shown in Figure 3, when rail 20 and vane group 30 were by parallel arbitrary height of transferring to window instantly, the blade 30a that top is unfolded still utilized trapezoidal ribbon (ladder string) 51 to come turning to of adjusting vane, and reaches the function of light modulation.The blade 30b that does not launch the bottom then is stacked on down the top of rail 20.

The go to action of trapezoidal ribbon 51 is controlled by a transfer 50, wherein the mode of operation of transfer 50 and the member that is mated use have the multiple different structure that changes, but its principle of carrying out steering operation all is similar, promptly at first with the upper end of the front and back two vertical rope 51a of each trapezoidal ribbon 51 and 51b respectively from front and back relative direction fixing respectively (for fixed location) in a upper face center that turns to body, this turns to body is that a support arm lever that waits that is horizontally set in the same rotating shaft turns to body, and has suitable arm distance at arm room.Utilize the rotating operation (or other modes are operated) of turner bar 52 to control the rotation that both forward and reverse directions 90 degree are done in rotating shaft again, and order about the lever that turns to body to make both forward and reverse directions 90 degree and rotate from horizontal level, thereby the relativity that two vertical rope 51a and 51b do one on the other before and after making moves, and then the vaned horizontal scalariform rope 51c of carrying is deflected, final blade reaches its dimming function also along with turning to.

The tradition horizontal type louver is in the user mode shown in Fig. 2 and Fig. 3, no matter the adjusting of draw off gear of its blade 40 and transfer 50, control mode are hand or electrodynamic type, up to the present existing multiple different structure, yet its purpose that can reach is nothing more than being to make that vane group 30 is can be from the upper end parallel to be put down and launch at arbitrary height, and promptly vane group 30 and following rail 20 are by the parallel arbitrary height that is lowered into the root edge place of window or rests on the window centre.During this horizontal type louver of reverse operation, rising vane group 30 and following rail 20 also draw in the below of last rail 10, make the place, below of vane group 30 and following rail 20 that a transmission region that does not have blade to cover fully be arranged.Therefore below the height that vane group 30 is stopped together with following rail 20, just can't utilize vane group 30 to cover the zone that to block again.But indoor, the Lower Half that often needs shielding window, the first half of window then needs the translucent effect that keeps good, even a middle part of wishing a shielding window is regional, and making two subregions, upper and lower part of window all can keep good translucent effect, this can't realize general existing horizontal type louver.

Resemble the U.S. the 5th, 443, No. 108 patents, its denomination of invention is the structure of UPWARDLY DEPLOYEDPRIVACY BLIND, though can above vane group, form the transmission region that does not have blade to cover, but its vane group is drawn in the lower edge at window, like this and be not suitable for the custom that common people use horizontal type louver, but and can obviously see the movable rail of upper and lower fixed track and middle another oscilaltion in whole horizontal type louver structure.A kind of hundred window shades (pleated shade) that are considered as having the top-down function of use are arranged in addition, there is a last rail that is fixedly arranged on upper window edge the top of this hundred window shade, whole window shade descends and leaves rail when using this hundred window shade, thereby the window shade top forms the transparent area that a no window shade covers.But this hundred window shades need be provided with on its body one coupled movable on rail, therefore go up rail as two from just seeing in appearance, one of them is the fixed rail of going up that is installed in upper window edge, another is the movable upward rail that itself is connected with hundred window shades.Control the movable rail of going up by the fixing member of going up rail inside and do lifting action, therefore the rail transverse arrest is obviously arranged in the activity on window when top-down uses.

It is a kind of through after improving that main purpose of the present utility model is to provide, and can all can produce the horizontal type louver of transmission region in the window upper and lower.

To achieve these goals, improved horizontal type louver in the utility model includes rail on, rail, a vane group, a cover include the blade draw off gear of the stay cord that can move up and down, the blade steering device that a cover includes many trapezoidal ribbons once.And the upper ends of the vertical rope in the front and back two of each trapezoidal ribbon no longer are provided with horizontal scalariform rope, but prolong the folding and unfolding rope that certain-length is arranged separately.At first make separately the folding and unfolding rope that prolongs respectively with movable circle around the turning on the body of an adjusting vane angle, again the folding and unfolding rope is wound on a reel and does and carry out synchronous folding and unfolding campaign.Adopt said apparatus, when vane group is expanded to arbitrary height from the top down, rotating operation by reel, make the upper blade of vane group continue to descend, above vane group, form one section complete transparent area that on-bladed blocks, and the vane group of launching turns to by transfer, thereby has dimming function.

Best, the reel and the rotating shaft of the folding and unfolding rope extension that will be used to reel all are arranged on rail inside.

Best, the reel and the transmission device of the folding and unfolding rope extension that will be used to reel are connected, and be convenient to the user and externally just can handle rotating shaft and do the both forward and reverse directions rotation, thereby control folding and unfolding rope is done synchronous folding and unfolding action.

Best, turning to body is the lever body such as support arm such as grade that is erected on the central axis, the extension of front and back two folding and unfolding ropes is at first passed the end aperture that turns to the body support arm respectively from the bottom up, after the direction of change folding and unfolding rope extension two folding and unfolding ropes are pulled to the lever center that turns to body, through changing the direction of folding and unfolding rope once more behind the lever center and being wound on the reel, make the folding and unfolding rope be movable pile warp and turning on the body and doing the free action of folding and unfolding up and down, thus make blade turn to function can by simple and easy, finish effectively.
