Description

Curtain roller rail

The utility model relates to the curtain rail technical field, belongs to the improvement of " slide block C shape guide bead ".

The structure of " slide block C shape guide bead " as shown in Figure 1.The section of track body is a C shape, and a fork-like farm tool used in ancient China one goes two stay cords 2 to place the inside of track body, and slide block 3 is solid plastic products, and slide block is along the open slot operation of track body side during use, and the bottom of slide block 3 hangs with cord.

Its advantage has:

(1) simple in structure, durable in use;

(2) stay cord is hidden in curtain rail inside, and outward appearance is good;

(3) slide block is solid, and bearing capacity is strong.

Its shortcoming is: friction is big, underaction during folding curtain curtain, and especially when cord was more thick and heavy, this shortcoming was more obvious.

Obviously, just can reduce friction if replace slide block, but do following several difficulty like this with roller:

(1) the true footpath of the axle of scroll wheel too hour, weight capacity is not enough, easily bending; The true footpath of the axle of scroll wheel is strengthened, and can influence " ratio of wheel, shaft diameter " again widely, and friction is increased.

(2) for to bring into play the little advantage of rolling friction power fully, roller will be in operation, its wheel rim does not rub with the other parts of track as much as possible mutually.If this strengthens the distance of track other parts and roller, then roller can be deviate from from open slot again at an easy rate.

(3) when drawing cord in, when two adjacent rollers are close to contact,, and cause roller pressured mutually, squeeze a ball because the direction of motion of contact point place two wheel rims is opposite, very easily Duan stay cord and wheel shaft.

More than be exactly why to reach on the market at present not see the reason that roller is applied to " C type curtain rail " in China's patent documentation as yet.

The purpose of this utility model provides and a kind ofly replaces slide block to reduce friction with roller, is applied to the Curtain roller rail on the C shape curtain rail.

The utility model is achieved in that the open slot of track body is in the side, downside at open slot is provided with track, be provided with roller in orbit, for improving " ratio of wheel, shaft diameter " to reduce its friction, this roller top is placed isolate in the frame, roll in orbit in the bottom of roller, connection is supported by isolating frame in the two ends of roller shaft, be connected with the curtain handle in the outside that isolates frame, this curtain handle combines as a whole with isolating frame, curtain hole on the curtain handle or hook be located at roller under.

For improving good looking appearance and result of use, also roller top can be placed in the cage, roll in orbit in its underpart, and the wheel shaft two ends are supported by cage and are connected, and are connected with the curtain handle in the outside of cage.

The effect of cage is identical with the isolation frame, has both improved bearing capacity, and when preventing that again cord from drawing in, card wheel phenomenon is avoided in adjacent roller wheel rim contact; Because isolate frame or cage each roller is placed in it, when cord draws in, only have the frame of isolation or cage to be in contact with one another like this, can not cause card wheel phenomenon.

The coincidence that can produce broad when cord is closed up can respectively be provided with as mentioned above a track in the both sides of track body, is provided with roller in it.

Because the utility model friction is less, thus the stay cord of the traction usefulness of track inside in addition can save need not, can reach the purpose that makes the curtain folding with the hand whipping.

Compared with the prior art the utility model has easy to use, flexible operation, advantage such as outward appearance is good.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is existing " slide block C shape guide bead " schematic diagram;

Fig. 2 is the horizontal cross-sectional schematic of the utility model monorail;

Fig. 3 is the horizontal sectional structure schematic diagram of the utility model two-orbit;

Fig. 4 is the horizontal cross-sectional schematic of pelmet that two two-orbits are arranged;

Fig. 5 is a two-orbit user mode schematic top plan view;

Fig. 6 (a) and (b), (c) are three kinds of embodiment that roller connects with track.

Referring to accompanying drawing 2: track body 9 available metal plates are rolling, also available plastics or aluminium alloy extruded one-tenth section bar, there is an opening groove 10 side of track body 9, downside at open slot is provided with the U-shaped grooved tracks 6 that supplies roller 11 walking usefulness, be provided with roller 11 in orbit, roller 11 tops place and isolate frame 12(if isolate the top sealing of frame 12, promptly become cage) in, wheel shaft 4 two ends are by isolating frame 12(or cage) the support connection, isolating frame 12(or cage) the outside be connected with curtain handle 5, this isolation frame 12(or cage) firmly combine as a whole with curtain handle 5, curtain hole 7 on the curtain handle 5 be located at roller 11 under, make the center of gravity of the center of gravity of cord, to improve the bearing capacity of roller 11 by roller.

Because 4 on the wheel shaft of roller 11 firmly links to each other with curtain handle 5 and isolate frame 12 isolating the connection of frame 12 upper supports, and the stressing conditions of roller shaft 4 is improved, and has strengthened its bearing capacity widely; Since cord hang over roller 11 under, under the effect of gravity, roller 11 can erectly walk in the U-shaped grooved tracks 6, and shaking amplitude is less, wheel rim is difficult for rubbing mutually with the object on next door; Because roller 11 rotates in isolating frame 12, the wheel rim of two adjacent rollers can not contact, and has fundamentally eliminated the possibility that roller and roller bear against mutually; Because the darker U-shaped grooved tracks 6 and the form fit of curtain handle 5 can limit roller effectively and deviate from from open slot 10.

Referring to Fig. 3, respectively be provided with a track 6 in the both sides of track body 13, be provided with roller 11 in it, traction stay cord 8 is placed in the open slot 10 on both sides, during actual the use, the configuration of curtain, rope, roller, fixed pulley as shown in Figure 5, by horizontal trolley 14, roller 11, drive two guide rollers 15 of cord operation, stay cord 8, track body 13, vertically pulley 16, be fixed in two rollers 11 of track body, about the intersection 17 of two width of cloth cords, the cord 18 that roller is hung down, manual stay cord end 19 is formed.As long as left and right cord is enough wide, just can make the intersection of curtain reach the width that needs.This has solved general curtain rail effectively, and also fashionable intersection is wide inadequately when cord, the problem that cord bottom easily grins out.

When pelmet will be hung two-layer cord, can adopt two two siding tracks, the visible Fig. 4 of the configuring condition that pelmet gets on the right track.

Certainly, the shape of track body reaches and the technical scheme that is used of roller is not limited in the above, also can adopt (a) and (b) shown in Figure 6, (c) scheme, their common ground is: use roller, roller in isolating frame or cage, track body, roller, isolation frame, curtain handle are designed to the shape that is unfavorable for that roller is deviate from by lateral opening groove place.

The utility model integrates the advantage of existing curtain rail, so can satisfy preferably the instructions for use in modern room, hotel, restaurant.
