Abstract

This creation is a curtain hem, which has a hollow structure. The upper and lower end surfaces of the hem main body are connected by two reinforcing ribs, so that the hollow structure of the hem forms a number of accommodating spaces, allowing the ladder rope and the counterweight to be placed in the accommodating space. , move the center of gravity of the hem down to increase the stability of the hem of the curtain; in addition, use the concave curved surface formed on both sides of the hem for its hands to kiss and grasp, so as to stably control the stacking of the curtain blades through the hem of the curtain.

Description

curtain hem

The invention relates to a curtain hem, especially a hem structure that can stably control the stacking of curtain blades and stably hang the hem.

The curtain hem is usually a member used to stabilize the operation of the curtain blade, so that the curtain blade can be kept upright. The typical hem structure is a solid structure, and there are several holes and slots at the bottom, which can cooperate with the cover to close the cover. When the ladder rope is wound to the bottom end of the hem, the ladder belt is fixedly connected with the fixed cover to control the flip of the hem; Since the traditional hem has a solid structure, the ladder belt is covered with a fixed cover, and the remaining ladder belt will be exposed outside the hem, which will affect the aesthetics of the curtain. Although the hem of the hollow structure can hide the ladder belt, it causes the center of gravity of the hem to become higher, which makes the hem easy to shake and affects the stability of the blade.

In addition, the traditional hem structure usually adopts an oblique plane design or a round convex structure on both sides. For a cordless curtain that uses the hem to control the stacking of the curtain blades, the traditional hem structure design is not conducive to the user's hand. The grab control affects the operation of the curtain blades.

The purpose of this creation is to provide a curtain hem that effectively maintains the upright or horizontal state of the curtain blade and is convenient for grasping the hem to control and operate the curtain blade. The upper and lower ends of the hem are connected with reinforcing ribs to form several accommodating spaces in the hollow structure of the hem, respectively accommodating the ladder belt and the counterweight, so that the lowering In addition to lowering the center of gravity of the hem and improving the appearance of the hem, the concave curved surfaces on both sides of the hem are designed for the operator's hands to kiss and hold, so that the hem can control the hanging or closing of the curtain.

In order to achieve the above-mentioned creative purpose, the curtain hem provided by this creation includes a hem main body, wherein the upper end of the hem main body is a plane structure, and two inner concave arc surfaces extending downward from both sides of the upper end plane structure are connected to the lower end arc surfaces, so that the structure is formed. The lower hem is designed with a hollow structure, and the upper and lower ends are integrally connected by reinforcing ribs. In addition to strengthening the strength of the hem, the hollow structure of the hem is divided into several accommodating spaces. The accommodating spaces are used to accommodate the ladder belt and place the counterweight. , to lower the center of gravity of the hem and improve the aesthetics of the hem.

In order to make the control of the curtain blades more convenient and stable, this creation is specially formed with a concave curved surface structure on both sides of the hem, which can be kissed and grasped by the operator's hand, so that the operator can control the hanging of the curtain with the hem. or collapse.

Please refer to FIG. 1 and FIG. 2 , the present invention mainly includes a lower swing body 1 with a hollow structure, wherein the lower swing body 1 has an upper end plane 10 , a bottom arc surface 11 and concave arc surfaces 12 and 13 on both sides and the connection The two reinforcing ribs 14 and 15 of the upper end plane 10 and the bottom arc surface 11; the inner concave arc surfaces 12 and 13 extend downward from the two sides of the upper end plane 10, and are connected with the bottom arc surface 11 by planes 16 and 17. The two reinforcing ribs 14, 15 are integrally extended from the upper end plane 10 to the bottom arc surface 11, so that the hollow structure of the hem main body 1 defines three accommodating spaces 18, 180, 181; the accommodating spaces 18, 180 , 181 are correspondingly configured with a cover body group, wherein the cover body group includes a first cover body 2 and a second cover body 3, and the first cover body 2 and the second cover body 3 have a cover plate 20, 30 and a combined body 21, 31, the shape system of the combined body 21, 31 is consistent with the accommodating spaces 18, 180, 181 of the hem main body 1, and the end faces are additionally provided with flanges 210, 310, through the flanges 210, 310 are tightly covered. The accommodating spaces 18 , 180 , and 181 are combined to form a closed space (refer to FIG. 3 and FIG. 4 ).

In addition, the bottom arc surface 11 of the hem main body 1 specially defines a through hole (not shown in the figure), and a cover 4 is closed correspondingly outside the through hole. The cover 4 has a flange 40 and a cover plate 41. The center of the cover plate 41 is closed. A through hole 42 is also opened at the place for the ladder belt 5 and the pull rope 6 to be threaded and fixed.

Please refer to FIG. 5 and FIG. 6 for the assembly instructions of the hem of the present creation. The cover 4 is mainly covered on the bottom arc surface 11 of the hem main body 1 , and the flange 40 is protruded from the accommodating space 180 , and The ladder belt 5 is wound from both sides of the hem main body 1 to the bottom arc surface 11 of the hem main body 1 and penetrated through the central hole 42 of the cover 4, and then fixed with a rope knot, so that the excessively long ladder belt 52 can be accommodated in the inside the space 180 (refer to FIG. 7 ); and the drawstring 6 is penetrated from the upper end plane 10 and then through the central hole 42 of the cover 4 , and the outer end of the bottom arc surface 11 of the hem main body 1 is fixed with a knot 7 , and then Then place the counterweight 8 in the accommodating spaces 180, 181 to lower the center of gravity of the hem main body 1, and finally place the first cover 2 and the second cover 3 toward the accommodating spaces 18, 18 180 and 181 are closed to complete the assembly of the hem body. The pull rope 6 is used to control the stacking of the hem body 1 and the blade 9 up and down, and the ladder belt 5 is used to control the opening and closing of the blade 9 (see Figure 8).
