Description

Technical Field

[0001] The invention relates to the technical field of curtain bottom beams, and in particular to a cloth-wrapped bottom beam profile and a cloth wrapping and installation method thereof. Background Art

[0002] The existing curtain bottom beam wrapping method usually adopts the method of directly wrapping the curtain cloth on the bottom beam, and in most cases, it is fixed by colloid. The advantage of this method is that it can make the whole curtain look more integrated and beautiful, and it can also reduce the noise generated when the bottom beam made of metal or plastic contacts the window frame.

[0003] However, this method also has some significant disadvantages. First, over time, the colloid used (especially double-sided tape) may lose its original stickiness, causing the curtain fabric to fall off the lower beam. This not only affects the overall appearance of the curtain, but may also prevent the curtain from working properly. Secondly, double-sided tape has different adhesion for different types of fabrics, which means that some fabrics may not adhere firmly to the lower beam, reducing the versatility and adaptability of this method. In addition, during the installation process, the operator needs to tighten the curtain fabric while pressing it to the lower beam to ensure the stability of the paste. This process requires certain skills and patience, which increases the complexity of the cloth wrapping work. If the curtain fabric does not achieve sufficient flatness and horizontal consistency when wrapping on both sides, the shading effect of the curtain will also be affected, and may even cause light leakage, reducing the functionality of the curtain.

[0004] In view of these limitations, it is particularly important to find a more reliable, efficient and easy-to-operate curtain bottom beam profile and its cloth wrapping method. Summary of the invention

[0042] Embodiment 1

[0043] As Figure 1 shown, this embodiment provides a lower beam profile 10 of the wrapping cloth, which includes an integrally formed wrapping part 11, a cloth hiding part 12, and a card slot 13; both the wrapping part 11 and the cloth hiding part 12 are in a "U" shape, and the length of the upper end part 111 of the wrapping part is less than the length of its lower end part 112; the upper end part of the cloth hiding part 12 is bent downward to form a first hook 121, and its lower end part is bent upward to form a second hook 122; the card slot 13 is obliquely arranged between the wrapping part 11 and the cloth hiding part 12, and the connection side of the card slot 13 with the wrapping part 11 is higher than the connection side of the card slot 13 with the cloth hiding part 12.

[0044] As Figure 2 shown, this embodiment provides a wrapping and installation method for the lower beam profile of the wrapping cloth, which is used to wrap the lower beam profile 10 of the wrapping cloth and install it at the lower end of the curtain cloth 30. The method specifically includes the following steps:

[0045] S1. Cut out a wrapping cloth 20 with a size sufficient to cover the lower beam profile 10 of the wrapping cloth, and fix one end of the wrapping cloth 20 on the hard strip 40 by means of welding, stapling, or bonding, etc. The width of the hard strip 40 is greater than the width of the slot opening of the card slot 13; the other end is fixed on the elastic sheet 50 by means of welding, stapling, or bonding, etc.

[0046] S2. Insert the hard strip 40 fixed with the wrapping cloth 20 from the side of the card slot 13, and the end of the hard strip 40 fixed with the wrapping cloth 20 is arranged on the connection side of the card slot 13 with the wrapping part 11, and the end face of the hard strip 40 fixed with the wrapping cloth 20 faces downward.

[0047] S3, tighten the wrapping cloth 20, and wrap it tightly on the upper end surface, the front end surface and the lower end surface of the wrapping cloth portion 11 from top to bottom, and then press the elastic sheet 50 fixed with the wrapping cloth 20 into the cloth hiding portion 12 from the first hook 121 and the second hook 122;

[0048] S4. Fix the lower end of the curtain fabric 30 on the hard strip 40 by welding, stapling or bonding, wherein the width of the hard strip 40 is greater than the slot width of the slot 13; insert the hard strip 40 fixed with the curtain fabric 30 from the side of the slot 13, and press one end of the hard strip 40 against the wrapping cloth 20 to provide a force to tighten the wrapping cloth 20.

[0049] The hard strip 40 may be a pressure strip with adhesive, or other hard sheets that can be fixedly connected to various fabrics. The elastic sheet 50 is a thin sheet with elastic force, which may be rectangular and have a thickness between 0.2 mm and 0.5 mm. The elastic sheet 50 may provide a force to tighten the wrapping cloth 20, so that the wrapping cloth 20 is tightly wrapped on the wrapping cloth portion 11.

[0050] Example 2

[0051] like Figure 3 As shown, this embodiment provides a cloth-wrapped lower beam profile 10, which is different from the embodiment 1 in that a groove 123 is provided on the front end surface of the cloth-hiding portion 12 for clamping the curtain fabric 30. Accordingly, the cloth-wrapping and installation method of the cloth-wrapped lower beam profile 10 specifically includes the following steps:

[0052] S1, cutting out a wrapping cloth 20 of a size sufficient to cover the wrapping cloth lower beam profile 10, and fixing one end of the wrapping cloth 20 to the hard strip 40 by welding, stapling or bonding, wherein the width of the hard strip 40 is greater than the slot width of the slot 13; and fixing the other end to the elastic sheet 50 by welding, stapling or bonding, etc.;

[0053] S2, insert the hard strip 40 fixed with the wrapping cloth 20 into the side of the card slot 13;

[0054] It should be noted that, although the end of the hard strip 40 fixed with the wrapping cloth 20 is arranged at the connection side between the slot 13 and the cloth-hiding portion 12, and the end face of the hard strip 40 fixed with the wrapping cloth 20 faces upward, this is not necessary in the present embodiment. The end of the hard strip 40 fixed with the wrapping cloth 20 may also be arranged at the connection side between the slot 13 and the wrapping cloth portion 11; the end face of the hard strip 40 fixed with the wrapping cloth 20 may also face downward;

[0055] S3, tighten the wrapping cloth 20, and wrap it tightly on the upper end surface, the front end surface and the lower end surface of the wrapping cloth portion 11 from top to bottom, and then press the elastic sheet 50 fixed with the wrapping cloth 20 into the cloth hiding portion 12 from the first hook 121 and the second hook 122;

[0056] S4. Fix the lower end of the curtain fabric 30 on the hard strip 40 by welding, stapling or bonding, wherein the width of the hard strip 40 is greater than the slot width of the groove 123; and insert the hard strip 40 fixed with the curtain fabric 30 into the side of the groove 123.

[0057] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value. The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention.
