Description

Hand-operated drive for opening and closing curtain

The utility model relates to a kind of transmission device of curtain account switch, especially a kind of transmission device of manual curtain account switch.

In existing various manual curtain account switch transmission devices, if the frictional property classification during with relevant moving component relative motion can be divided into following two big classes substantially: first sliding friction class.This is general, a most original a kind of manual curtain account switching device, and the rail profile of its sliding rail is generally the C type, during work moving component can be in track sliding motion.This sliding type is simple in structure, but because coefficient of friction is bigger, so relatively require great effort during switch curtain account.It two is rolling friction classes, and its rail profile is made simply usually Type, moving component rolling movement in orbit during work is so coefficient of friction is less.

But all there is common weak point in use in the manual curtain account of above-mentioned two classes switching device.At first, owing to all adopt three pulleys, one structure of tow line during the work of the manual curtain account of this two class switching device, stay cord is not separated with other moving component that moves in track of sliding track again, when being in relaxed state, stay cord very easily produces the displacement of beating, even twine with other moving component and card rope accident takes place, can make the stay cord fracture when serious.Secondly because that normally used slide rail length needs is consistent with the length of curtain account, long track also for storage, transport and carry and brought inconvenience.

The purpose of this utility model just is to provide a kind of manual curtain account switching device that not only is difficult for generation card rope accident but also can makes slide rail length can contract and roll over.

Invention main points of the present utility model are to have adopted a kind of section to be The transmission mechanism of the special sliding rail of type and two backguys of four pulleys reaches above-mentioned first goal of the invention, but has adopted the combination of contractible track to reach second goal of the invention.

Figure 1 shows that schematic diagram of the present utility model, the schematic diagram when wherein (b) is slide rail section and work;

But Figure 2 shows that contractible slide rail jockey schematic diagram;

Figure 3 shows that the tenon joint type connection diagram of curtain account calibrator;

Figure 4 shows that the embodiment when the utility model is used for plane curtain account;

Figure 5 shows that the embodiment when the utility model is used for three-dimensional curtain account.

The utility model can be made of slide rail (1), turning rolls (2), (3), suspension arrangement (4), curtain account calibrator (11) and pulley, cotton rope.The section of track of sliding track (1) is Type, its middle part orbit space is a sipes, the sealing of sipes upper wall, Zuo Bi, right wall and lower wall then can respectively be kept somewhere a breach.The space, both sides of track of sliding track is narrow slot space, and the sidewall that this narrow slot space is adjacent with the sipes space can be connected two space-likes by breach.The effect of sipes is to make turning rolls (2), (3) and suspension arrangement moving components such as (4) to move along this rail, narrow slot space has then limited the scope of activities of cotton rope, thereby has avoided the displacement because cotton rope lax beats and the motion of disturbed motion parts.Among the figure, (2) and (3) are turning rolls.Turning rolls can form by the suspension arrangement that is fixed for the hanging curtain account on roller.(4) suspension arrangement can be forms such as hook, folder, ring, only is that embodiment illustrates with the hook among the figure.Suspension arrangement (4) can directly snap in track and slide, and can be installed in indirectly also that (as roller, ball etc.) roll along track on the tourelle.(7), (8), (9), (10) are 4 pulleys among the figure, and wherein two (7), (8) can lay respectively at the two ends of slide rail (1) as the interlock pulley, and two pulleys (9), (10) can be positioned at arbitrary end of track as angle pulley in addition.Article two, (5) are train line in the cotton rope, and this line can connect into a closed-loop with turning rolls (2), (3) with interlock pulley (6), (7); The two ends of another cotton rope (8) rely on gravity to dangle as line of pull naturally after then can being individually fixed in and also can passing through two angle pulleys (9), (10) respectively on two turning rolls.As long as drive the motion of any one turning rolls with line of pull, then another turning rolls will produce relative motion, and the sequence of motion of turning rolls has promoted the motion of each moving component, thereby has driven the unlatching of whole curtain account or close.The material of cotton rope is advisable can bear suitable pulling force, can adopt various ropes, chain, band etc. with suiting measures to local conditions.

For the ease of preserving, transporting and carry, long sliding rail can be made the short rails of some joints and be formed by connecting.By the thin plate match with the rail profile geometric shape is set respectively on the connection end point of track as clip, and on clip, set in advance the stationary positioned device, clip is installed on short rail end points also through the short rails of some joints being connected the growth rails after the positioning and fixing.Fig. 2 shows a kind of radial type positioning and fixing jockey that is provided with on clip.In Fig. 2, clip (12) is

The type thin plate can be connected into long rail at the articulated slab (13) that is shaped on the band locating hole on the clip (12) and by latch (14) is interdigital with articulated slab (13) with lacking rail after hinged.When with the latch being the central shaft rotation, can realize on short rail the folding that contracts of slide rail.

For plane curtain account, can directly hang on turning rolls and the suspension arrangement (4), but concerning three-dimensional curtain account, for the design that keeps the curtain account has then needed to be provided with separately curtain account calibrator.Curtain account calibrator (11) often adopts the closed curve framework.In the utility model, match for the ease of short slide rail with the folding that can contract, can consider also to make this curtain account calibrator dismountable and be illustrated among Fig. 3.The closed curve framework of this curtain account calibrator can be made of two parts symmetrical, and the top of each several part and sidepiece all can be provided with some hangers, as hole, hook, folder, ring etc.On two-part joint face, then can set up some tenons (15) and the mortise (16) that matches with it separately, tenon is inserted mortise after, can make two symmetrical independent sectors be combined into a complete curtain account calibrator (11).

The utility model is because based on rolling friction, so coefficient of friction is less, it is all very laborsaving to open and close the curtain account.Because the interlock rope (5) in the cotton rope is limited in narrow gauge top and in tension all the time, so it is lax can not hang, and stay cord (6) is limited in the narrow gauge bottom all the time, and two ropes are isolated with track with other moving component, so do not block the sorrow of rope.From mechanical analysis as can be known, special track of sliding track Section Design is improved the track flexural strength in the utility model, therefore its flexural deformation is reduced, and is particularly suitable for adopting some costs low but use usual method to be easy to produce diastrophic material and make, as plastic material.

The utility model can be used as the manual switchgroup of various planes curtain, three-dimensional curtain account, can be widely used in various occasions such as hotel, family, office.Because it is easy, with low cost that the utility model is drawn materials, and helps more applying.
