Abstract
A roller blind has an operating mechanism in the form of an elongated pulling means running over a wheel (11) so as to form two strands (21, 22; 24, 25). This pulling means may be, e.g. a ball chain (20) or a plain cord (23) and the wheel may be a cog-wheel. The cord and the wheel are adapted in such a manner that the cord slips on the wheel when one of the strands is pulled except when a counterforce is applied to the other trailing strand.
Description
Technical field
The present invention relates to a kind of roller shutter of stay cord on the swiveling wheel that have.
Background technology
Usually, such roller shutter has the pelletron of a ring-type, and this circulus exists certain danger, promptly possibly cause children's head to be stuck in the ring-type pelletron of this sealing.One of them problem to be solved by this invention is exactly under the situation that does not increase manufacturing cost, to eliminate this danger.
Summary of the invention
The invention provides a kind of safe volume chain pelletron; Solved the technical problem that the annular pelletron that exists in the prior art damages children easily.
The technical scheme that the present invention adopted is: a kind of roller shutter, include the frame for movement that a control roller shutter goes up and down, and this frame for movement comprises an elongated drag cable; The drag cable solderless wrapped connection is on a roller, and drag cable is separated to form two sections stay cords by roller, it is characterized in that: drag cable is open; Be that drag cable has two free ends; Regulate drag cable and roller, make only wherein on other one section stay cord, to apply the rotation of a reaction force ability driving rolls in one section stay cord, when only spurring one section stay cord in pulling; Stay cord can only slide on roller, and can not rotate by driving rolls.
As preferably; Described drag cable is a pelletron; Pelletron is to be made up of a plurality of spherical bead, and roller surface is provided with the spherical surface of each globule of pelletron and cooperates the arc teeth groove, and the degree of depth of teeth groove makes a end at pelletron under the situation that does not apply reaction force; Pelletron can only slide in the teeth groove of roller, and can not drive the roller rotation.
As preferably, described drag cable is a smooth rope, and rope is solderless wrapped connection one circle on roller, and the solderless wrapped connection angle is greater than 180 °.
As more preferably, the solderless wrapped connection angle of rope is greater than 270 °.
This pelletron is an Open architecture; Promptly be not the ring-type of a sealing, pelletron promptly forms two sections stay cords on swiveling wheel, swiveling wheel and stay cord is set to following particular state; When promptly only drawing any one section stay cord; Pelletron only can slide on the swiveling wheel surface, has only while people on another section stay cord just can to rotate by the driven in rotation wheel for applying a reaction force.Utilize this operation, promptly need not to have re-used the pelletron of ring-type.

Fig. 2 is the exploded perspective view of the present invention for Fig. 1.
Fig. 3 is the present invention has made the roller shutter of partly revising to Fig. 1 a perspective view.
Fig. 4 is the explosive view of Fig. 3.
The specific embodiment
Through embodiment, do further bright specifically below to the technical scheme of invention.
Embodiment 1:
A kind of roller shutter, Fig. 1 and Fig. 2 have been showed a wherein end of roller shutter, comprise roller 11 and gear 12 attached to it; On the axle journal 13 of the end of the axis of rotation of roller shutter, be provided with a square jack 14; Carriage 16 is fixed on the wall, and its inboard is provided with a square bolt that is complementary with square jack 14 sizes (showing in the drawings).Roller 11 is fixed on the curtain rolling shaft; Axle journal is plugged in the centre bore of roller; There is the part face to intersect between the axle journal 13 of roller and end; In case surpassed the frictional force between roller and the crossing face of axle journal during operation pelletron 20 rotation rollers 11, roller 11 can be done freely with respect to fixing axle journal 13 and rotate.This for the frame for movement that prevents the inessential rotation of roller shutter ubiquity, do not giving unnecessary details at this.
Pelletron 20 on the swiveling wheel that has gear 12 11, so make pelletron 20 be divided into two sections, stay cord 21 and stay cord 22.
Gear 12 surperficial ring-types relatively each pearl of pelletron of arranging, more shallow teeth groove relatively, adopting this mode is not to be meshed between ripple pearl and the gear when only drawing any one section stay cord in order to make.
For the ability rotation roller, make roller shutter to go up and down, in one section stay cord of traction, need hold another section stay cord, be meshing with each other to produce a reaction force, so just can make between ripple pearl and the gear, so that roller rotates, go up and down thereby drive roller shutter.Then, can retract initial position to previous upborne one section stay cord, only otherwise on another strand stay cord, apply reaction force, neither can cause the rotation of roller.Above-described this method can repetitive operation, so that roller rotates once more.
Can be according to above this cover method of operating by the fact of continuous repetition, the pelletron that re-uses the sort of closed circular just seems and there is no need, and this also lets the relatively short open pelletron of use become possibility.
Enforcement power 2:
Like Fig. 3 and shown in Figure 4, a kind of roller shutter has wherein been replaced the pelletron of original use by a stay cord with circular section, serve as the traction material.Fig. 4 has showed the state that roller 11 separates from curtain rolling shaft one end, and Fig. 3 displaying is the state that roller and curtain rolling shaft link together.Represent with numeral 23 and 24 respectively for two sections of stay cord.Stay cord 23 is around 11 1 weeks of swiveling wheel, and promptly it has bigger angle of bend, and angle of bend is at least greater than 360 degree in this embodiment.The angle of bend of stay cord depends on the own and interaction force of stay cord and roller, and the function that has reached the embodiment that is showed like Fig. 1 and Fig. 2 is the same,, makes that roller 11 just begins to rotate when other end stay cord receives certain reaction force that is.If the frictional force between stay cord and the roller is bigger, the angle of bend of stay cord needn't look like among this embodiment so big so.In some cases,, that is, make that the angle of bend of stay cord is 180 degree, although this needs relatively bigger reaction force make roller 11 rotations as long as directly hang over stay cord on the roller 11 just enoughly.In order to increase frictional force, the two strands of stay cords of controlling that can be artificial intersect below swiveling wheel 11, increase angle of bend, reach for example 270 degree or bigger.
Fig. 3 and Fig. 4 have also showed the side of projection 26, and it above gear 12, is used to prevent that pelletron 11 from skidding by device, and it is applicable to the pelletron that uses conventional circular and is not suitable for use stay cord 23.If use stay cord certainly as drag cable, use gear 11 just to there is no need so, can use a ganoid roller to replace.
Can make change with stay cord or pelletron as the example of drag cable material like what the embodiment of the invention was showed, for example use flat ribbon also can realize.Other any type of changes all possibly drop in the protection domain of claim of the present invention.
