Description

Universal mechanism for curtain rope

The invention relates to a curtain, in particular to a universal mechanism of a curtain rope that can follow the rotation direction of the rope.

The general curtain set, as described in the new patent case M497501, will use a track and a curtain when in use, the track is fixed on the ceiling or the side wall, and there will be several pull cords in the track to drive the curtain, the pull The change in the length of the rope will cause the curtain to rise or fall. The shorter the rope is, the higher the curtain will rise. In order to connect the curtain with the curtain, the track will be provided with a corresponding Opening holes for pulling rope.

In the case of the curtain group, the pull cord is connected to the curtain, so the pull cord will bear the weight of the curtain, and because the pull cord passes through the opening, the pull cord will be pressed against the opening after being weighed. The side wall of the hole, and produce a friction effect, except when pulling it will be more laborious because of the friction force. In addition, because the pull rope and the opening remain in a friction state for a long time, the pull rope is likely to break after a long time. Damage; if you want to avoid the friction between the opening and the drawstring, some will increase the area of the opening. In this way, although the friction can be avoided, the position of the drawstring will not be fixed when it is retracted. The drawstring will be entangled and cannot be untied, making the drawstring unreleased.

The main purpose of the present invention is to provide a mechanism that can change direction with the weight-bearing position of the rope.

In order to achieve the above object, the present invention provides a universal mechanism for curtain ropes, including: a top rail group with a track and at least one rolling mechanism, the track is provided with at least one opening; and at least one universal The mechanism includes a pivot plate and a rotating wheel, each pivot plate is pivotally disposed in each opening, and each pivot plate is centrally provided with each pivot wheel.

The universal mechanism of the curtain rope of the present invention, when it is used in curtains, the rope will slide on the universal mechanism, and when the rope is pulling the curtain, the runner of the universal mechanism will rotate as the rope rises and falls, The friction force of contact can be reduced; and the pivot plate of the universal mechanism will rotate because of the different direction of the weight of the rope, so that the pull rope can perform the action of lifting the curtain at a better force position. Make its operation smoother.

Please refer to FIGS. 1 to 4, which is a preferred embodiment provided by the present invention, which is a curtain group 20 including:

A top rail group 30, as shown in FIGS. 3 and 4, has a rail 31 and a rolling mechanism 32. The rail 31 has an accommodating space 311, and an opening 312 is formed at the bottom of the rail 31 The accommodating spaces 311 are in communication. In this embodiment, in order to display the structure clearly and clearly, only a single opening 312 is provided, which can be adjusted and set according to actual needs, and is not limited to the single opening 312; The winding mechanism 32 is disposed in the accommodating space 311, and a winding portion 321 is provided corresponding to the opening 312. Each winding portion 321 is also provided with a rope 322. The structure of the winding mechanism 32 is also conventional The known design will not be described in detail here. It can also use other rope retracting structures to retract and unwind the rope, not limited to the retracted structure;

A universal mechanism 40, please refer to FIGS. 1 to 4, it includes a pivot plate 41 and a rotating wheel 42, the pivot plate 41 is pivotally arranged in the opening 312 from the side of the accommodating space 311 Inner; the bottom of the pivoting plate 41 is protruded with at least four claws 411, the claws 411 includes a cantilever 412 and a buckle 413, each buckle 413 is elastically limited to the bottom of each opening 312, Each pivoting plate 41 and each buckle 413 are located on both sides of the openings 312 respectively; the pivoting plate is recessed with two sets of connecting grooves 414 and two bearing grooves 415, the two sets of connecting grooves 414 and The bearing grooves 415 are opposite to each other, and the two sets of connecting grooves 414 and the two bearing grooves 415 are arranged approximately vertically; the rotating wheels 42 are provided with a wiring groove 421 around the circumference, and the rotating wheel 42 has a shaft A shaft 422 is penetrated in the center of the core, and both ends of the shaft 422 are pivotally arranged in the grouping grooves 414, and the wiring groove 421 is disposed at the outer edge of the bearing groove 415, and the bearing groove 415 is The opening of the wiring groove 421 is opposite, so that a closed space is formed between the wiring groove 421 and the bearing groove 415, and the pull cord 323 is passed around the closed space between the wiring groove 421 and the bearing groove 415 and then protrudes to the Outside of track 31;

A curtain 50 is disposed outside the track 31, and the rope 323 is connected to the curtain 50.

Please refer to FIGS. 3 and 4. When the curtain 50 is to be adjusted to a high or low position, the scrolling mechanism 32 is driven so that the scrolling portion 321 can rotate clockwise or counterclockwise, and then the rope 323 can be adjusted. The length of the rope 323 on the outside of the track 31 will relatively change the position of the curtain 50; when the length of the rope 323 is longer, the curtain 50 will be longer, and when the length of the rope 323 is shorter, the curtain 50 is also Will be shorter.

Please refer to FIG. 4, when the rope 323 is connected to the curtain 50, the weight of the curtain 50 itself will be added to the rope 323. At this time, when the rolling part 321 is being rolled, because the The rope 323 will pass around the connecting groove 421 of the runner 42, and the runner 42 can rotate on the shaft 422, which can reduce the frictional force when pulling. In addition, because the connecting groove 421 and the two bearing grooves 415 forms a closed space, so the rope 322 is not easily detached from the sealed space, but can ensure its smooth rolling effect; moreover, please refer to Figure 5 (A) and (B) as shown in the curtain When retracting, the position of the center of gravity of the rope 50 will change, and the direction of the gravity of the rope 323 under the curtain 50 will also change relatively. At this time, the rope 323 will give the runner 42 a lateral force, so that the runner 42 can drive the pivot plate 41 to rotate in the opening 312, so that the runner 42 can rotate to the direction of the force, and then continue to pull the rope 323, so that the rope 323 can reduce resistance during the pulling process.

Please refer to FIG. 6, which provides a second preferred embodiment of the present invention. Its main structure is the same as the previous embodiment, so it will not be described in detail. Among them, the track 31 of the top rail group 30 is provided with Two sets of different rolling mechanisms 32a and 32b. The two rolling portions 321a and 321b of the two different rolling mechanisms 32a and 32b are respectively provided with two ropes 322a and 322b. The two ropes 322a and 322b can pull different curtains (Not shown); the track 31 is relatively installed with two universal mechanisms 40a and 40b, the two universal mechanisms 40a and 40b are provided at the center of the track 31, and the two rolling mechanisms 32a and 32b are When the two ropes 322a and 322b pass through the two universal devices 40a and 40b, the two rolling parts 321a and 321b will have an angle with the two universal devices 40a and 40b , So that the two pull cords 322a and 322b will relatively drive the universal mechanism 40a and 40b to rotate to a better angle for traction.

In the curtain assembly provided by the present invention, the universal mechanism 40 provided on the opening 312 of the curtain 42 is used to smoothly pull the rope 322 through the runner 42 to avoid a large amount of friction directly passing through the opening 312 as is conventional Improve service life and smoothness of use. In addition, the runner 42 can rotate the drive plate 41 so that the runner 42 can rotate on the opening 312 and can be adjusted to an appropriate pulling position to prevent the rope 322 from being broken due to improper force. The direction mechanism 40 can control the position of the rope 322, so that the rope 322 can be wound in order, and the winding problem caused by the unstable position when the rope 322 is wound can be avoided.
