Description
(1) technical field
The present invention relates to the chain-drive mechanism of ornamental sun blind, especially relate to a kind of chain-drive mechanism that can be used for being sealed in the bottom-fixed blind curtain that uses in the hollow glass.Belong to the decorations technical field.
(2) background technology
Sun blind can be regulated the light function and used widely because of having.But the sun blind of existing all kinds of cross blades all belong to overhead type basically, that is to say that sun blind blade when drawing in all concentrates on the top.This class formation is difficult to satisfy people's different demands in many instances when using.As people during in indoor activity, for daylighting effect and the outer people's sight of while air lock that reaches indoor maximum, wish curtain only to intercept the sight line of window the latter half and guarantee the daylighting of window the first half, and existing sun blind just are difficult to accomplish this point, because its blade just can cover the bottom of window after must all launching from top to bottom.For reaching this purpose, people have done various improvement designs to horizontal stripe formula sun blind.
For example, aspect the stay cord control of external hanging type blind.Chinese patent application number 02151751.7, name is called " a kind of dragline type blind curtain ", Japanese patent application No. JP8082174, name is called in the patent application of " VERTICALLYOPENABLE/HORIZONTALLY OSCILLATING BLIND " etc., at the bottom of all reaching the control sun blind on the function substantially, put the purpose that the blade rising launches and blade overturns, but because curtain rope needs pulling control respectively, be easy to cause the not parallel arrangement of curtain blade in actual use, influenced its result of use.
Aspect the rotating shaft control of the blind of electronic control, particularly can pack into sun blind in the hollow glass, Chinese patent application number 00106691.9, name is called " a kind of preparation method of rotation shaft regulated venetian blinds ", Chinese patent application number 00235056.4, name is called " rotation shaft regulated venetian blinds ", Chinese patent application number 03106508.2, name is called " the vane type sun blind are put at a kind of end ", European Patent Application No. EP1213437, name is called " Lamellar blind with tiltingmechanism ", international patent application no WO2007064215, name is called " A SYSTEM FOR ELEVATINGAND LOWERING A LIGHT AND/OR VISION IMPEDING ARRANGEMENT ", though having solved sun blind rises from bottom to top and launches and blade rotates the problem of adjusting at an arbitrary position, but because complex structure, transmission inconvenience, need occupation space bigger, in the hollow glass of sealing, use especially, there is certain difficulty, is necessary to do further improvement.
(3) summary of the invention
1, purpose
The invention provides a kind of chain-drive mechanism of bottom-fixed blind curtain, it can overcome the deficiencies in the prior art, and its novel structure is with low cost, easy to use.
2, technical scheme
The chain-drive mechanism of a kind of bottom-fixed blind curtain of the present invention, it is to be made of left and right metallic bond, left and right upper sprocket wheel, left and right friction pulley, power transmission shaft, trip shaft, bearing, loose slot, key way etc. down; On the window frame left side, left metallic bond one end is fixed on the window frame upper left side, and the other end is a free end, and this left side metallic bond freely is suspended in the key way after walking around lower-left friction pulley, upper left sprocket wheel; On window frame the right, be symmetrical arranged the same with the left side, promptly right metallic bond one end is fixed on the window frame upper right side, and the other end is a free end, and this right side metallic bond freely is suspended in the key way after walking around bottom right friction pulley, upper right sprocket wheel; Left and right friction pulley down is installed in the trip shaft two ends, and trip shaft passes bearing and supported by it, and bearing is connected with loose slot; Left and right upper sprocket wheel is installed in power transmission shaft two, and power transmission shaft is connected with dynamical system; When the dynamical system of curtain (motor-driven or by the contactless driving of the magnetic control of magnetic line of force effect) entry into service, the whole chain transmission mechanism of curtain carries out work.The rotation of this left and right upper sprocket wheel has spurred left and right metallic bond and has moved back and forth up and down, thereby drives also correspondingly deflection up and down, expansion and gathering of curtain blade.
Friction pulley in the such scheme also can substitute with sprocket wheel, and promptly left and right friction pulley down can substitute with left and right upper sprocket wheel.At this moment, described sprocket wheel both can fixedly also slidably be connected with trip shaft, thereby can realize deflection up and down, expansion and the gathering of curtain blade.
Consider different occasions and demand, above-mentioned chain-drive mechanism also is applicable to the curtain of other structural shape, as similar curtain such as shutter curtain, curtains.
3, advantage and effect
The chain-drive mechanism of bottom-fixed blind curtain, simple, easy to use, particularly this acyclic chain drive can realize in not same plane, has increased its scope of application greatly.The blade deflection of sun blind, expansion and gathering all well obtain Synchronization Control.
