Spacing limiting device

Technical Field

The utility model relates to a fittings for curtains technical field especially relates to an interval limiting device.

Background

When the curtain is used, friction force exists between the hanging piece and the guide piece, and when the friction force is too large, the curtain cannot move smoothly along the guide piece, so that the curtain cannot be opened and closed normally. Especially for the curtain with the through-type curtain matched with the Roman rod, when the curtain is pulled open, the adjacent Roman rings are arranged in a splayed mode on the Roman rod, and because Luo Majuan is moved by the curtain, for example, the curtain is pulled from the right side, the distance between the adjacent Luo Majuan is smaller and smaller along the length direction of the Roman rod as the position is farther and farther from the right side. This results in the curtain between adjacent left-hand roman rings being in a relaxed state, which results in the right-hand roman ring moving while the left-hand side Luo Majuan of the roman ring is stationary, which increases the overall friction because the static friction is greater than the dynamic friction, and in this case, the curtain is difficult to close or open. When the curtain is an electric curtain, the influence caused by the frictional resistance is more obvious, the general loading force of a curtain motor is smaller, and when the frictional resistance is larger, the curtain motor can stop when meeting the resistance, so that the problem that the curtain can not be opened or closed is caused.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for descriptive purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

For such a window covering with a pass-through blind fitted to the roman pole, when the window covering is pulled open, adjacent roman rings are splayed on the roman pole, and since Luo Majuan is moved by the blind, for example, by pulling the window covering from the right side, the spacing between adjacent Luo Majuan becomes smaller and smaller as the position becomes farther from the right side along the length of the roman pole. This results in the curtain between adjacent left-hand roman rings being in a relaxed state, which results in the right-hand roman ring moving while the left-hand side Luo Majuan of the roman ring is stationary, which increases the overall friction because the static friction is greater than the dynamic friction, and in this case, the curtain is difficult to close or open. When the curtain is an electric curtain, the influence caused by the frictional resistance is more obvious, the general loading force of a curtain motor is smaller, and when the frictional resistance is larger, the curtain motor can stop when meeting the resistance, so that the problem that the curtain can not be opened or closed is caused.

In addition to the top contact point, the side of each roman ring may also contact the roman rod and create frictional resistance, and when the distance between two roman rings is large, the tension of the curtain causes the side of two adjacent roman rings Luo Majuan to contact the roman rod, and the cumulative resistance of the plurality of roman rings is very large, thereby increasing the overall frictional force, in which case the curtain may be difficult to close or open.

In order to solve the problem, the Roman ring can be prevented from tilting by limiting the tilting angle of the Roman ring when the curtain is pulled open, so that the horizontal two sides do not generate friction resistance with the Roman rod. For example, the scheme for limiting the inclination angle of the Roman ring when the curtain is pulled open is characterized in that two parts of the clamp are respectively fixed on the curtain above two adjacent Luo Majuan, the inclination angle of two adjacent Luo Majuan is limited by limiting the angle between the two parts of the clamp, so that the horizontal two sides of the Roman ring do not generate friction resistance with the Roman rod, the whole friction resistance is reduced, and the problem is solved.

However, this solution has great limitations, for example, the specifications of the window curtains on the market are very many, the distance between two adjacent roman rings is not uniform, and the solution of the prior art solution to the problem of non-uniform distance between two adjacent roman rings may adopt clips with different specifications and lengths, or telescopic clips. Therefore, a new problem is caused, and when the clamp is made into different specifications and lengths, the clamp with various types brings higher production cost and higher installation difficulty no matter in the production, manufacturing or installation and use processes; when the clamp is made into a telescopic structure, the problems of complex structure, increased cost and increased weight of the clamp are faced, and the increased weight of the clamp not only increases the friction damping between the contact point on the top of the roman ring and the roman rod, but also causes the deformation of the upper part of the curtain and introduces a new problem.

Optionally, the telescopic laminated body is a curtain cloth, luo Majuan is arranged on the curtain cloth, the plurality of fixing assemblies 2 can be fixed to the upper edge of the curtain cloth, and one fixing assembly 2 is arranged between every two adjacent roman rings, so that the distance between every two adjacent roman rings is limited, the condition that the roman rings are in a static state is reduced, the overall friction resistance is reduced, the curtain cloth is unfolded more uniformly, and the problem of inconsistent light transmission degree is solved; under the action of the wavy structural arrangement of the curtain cloth, the inclination angles of the two adjacent Luo Majuan are limited, so that the horizontal two sides of the Luo Majuan do not generate friction resistance with Roman rods as far as possible, and the whole friction resistance is reduced again.

And, fixed subassembly 2 is in the (window) curtain of different roman circle intervals can be adjusted, applicable in the (window) curtain of different roman rings intervals, need not complicated extending structure, fixed subassembly 2 only needs the effect that has centre gripping or hasp, can be fixed in the curtain, coupling assembling 1 only need be flexible rope or flexible area, consequently interval limiting device 100's weight is also lighter relatively, can not additionally increase more Luo Majuan overhead contact point and the friction damping between the roman pole, also be difficult for causing curtain upper portion to warp, and the practicality is strong.
