(16) As show in FIG. 2 and FIG. 3, the lateral flexible splicing assembly 4 includes a fastening band 41 and a planar fastening cloth 42 as shown in a shaded portion of the figures. The fastening band 41 is fixed at a backlight surface of the lower curtain piece 3 by stitching; and the fastening cloth 42 is fixed at a sun-facing surface of the upper curtain piece 2 by stitching, and at least a peripheral portion of the fastening cloth 42 is stitched at the upper curtain piece 2, such that the lateral flexible splicing assembly 4 can be well concealed when viewed from a front of the curtain 1, and whole of the lateral flexible splicing assembly 4 is placed at a valance position, effectively ensuring the overall aesthetics of the curtain. The fastening cloth 42 is the first splicing part of this embodiment, and the fastening band 41 is the second splicing part of this embodiment.

(17) As the fastening cloth 42 is covered with soft fiber loops on a binding surface of the fastening cloth 42, and the fastening band 41 is covered with hooks, such that the fastening cloth 42 and the fastening band 42 can be detachably bound.

(18) In this embodiment, the fastening cloth 42 is fixed at a lower end portion and a middle portion of the valance, and a lower edge of the fastening cloth 42 is aligned with a lower end edge of the fastening. The fastening band 41 is fixed at an upper end portion of the curtain body, and an upper edge of the fastening band 41 is aligned with an upper end edge of the curtain body.

(19) Since a longitudinal size of the fastening cloth 42 is larger than that of the fastening band 41 and bindable positions are continuously arranged to present a planar structure, specifically, the longitudinal size of the fastening cloth 42 is twice or even ten times more than that of the fastening band 41, that is, in this embodiment, the first splicing part is a planar splicing structure.

(20) During the usage, the fastening band 41 separated from the fastening cloth 42 is adjusted in a longitudinal direction and then bound to a corresponding position of the fastening cloth 42 to adjust a spacing between the upper end edge and the lower end edge of the curtain 1, that is, the longitudinal size of the curtain 1 is adjusted to match height requirements of the actual installation scene.

(21) In this embodiment, as the fastening cloth 42 is a continuously arranged planar splicing structure in a bindable area and in the longitudinal direction, such that there are theoretically numerous splicing positions, and the positional difference of these splicing positions in the longitudinal direction may be any value.

(22) In this embodiment, not only the adjustment of the longitudinal size of the curtain 1 can be achieved, but also the disassembly and assembly of the curtain body 3 during the cleaning process can be facilitated, and the curtain body 3 with different structures or patterns can be replaced according to the application scene and season.

Curtain of a Second Embodiment

(23) See FIG. 4 to FIG. 5, this curtain includes an upper curtain piece 2, a lower curtain piece 3, and a lateral flexible splicing assembly 4 used to detachably splice the upper curtain piece 2 and the lower curtain piece 3. In this embodiment, the upper curtain piece 2 is a valance, and the lower curtain piece 3 is a curtain body, that is, this curtain embodiment of the invention is a splicing structure having a short upside and a long downside spliced by the valance and the curtain body.

(24) The lateral flexible splicing assembly 4 includes a fastening band 41, a planar fastening cloth 42 as shown in a shaded portion of the figure, and laterally arranged adhesive tapes 43. During the binding process of the fastening band 41 and the fastening cloth 42, the binding position is aligned by the adhesive tape, that is, the adhesive tape 43 is the binding alignment strip in this embodiment. The fastening band 41 is fixed at a backlight surface of the lower curtain piece 3 by stitching. The fastening cloth 42 is fixed at a sun-facing surface of the upper curtain piece 2 by stitching, such that the lateral flexible splicing assembly 4 can be well concealed when viewed from the front of the curtain 1, and whole of the lateral flexible splicing assembly 4 is placed at the valance position, effectively ensuring the overall aesthetics of the curtain. The adhesive tape 43 is pressed onto the binding surface of the fastening cloth 42 by press gluing, that is, the adhesive tape 43 is attached to a part of the bonding surface S of the fastening cloth 42 to cover this part of the bonding surface S, such that the fastening band 41 is not bound to this part of the bonding surface S. The fastening cloth 42 and a plurality of adhesive tapes 43 fixed at the fastening cloth 42 form the first splicing part of this embodiment, and the fastening band 41 forms the second splicing part of this embodiment.

(25) As the fastening cloth 42 is covered with soft fiber loops on the bonding surface S of the fastening cloth 42, and the fastening band 41 is covered with hooks, such that the fastening cloth 42 and the fastening band 41 can be detachably bound.

(26) In this embodiment, the fastening cloth 42 is fixed at a lower end portion and a middle portion of the valance, and a lower edge of the fastening cloth 42 is aligned with a lower end edge of the valance. The fastening band 41 is fixed at an upper end portion of the curtain body, and an upper edge of the fastening band 41 is aligned with an upper end edge of the curtain body.

(27) In this embodiment, the adhesive tapes 43 divide the bonding surface S of the planar fastening cloth 42 into a plurality of strip-shaped fastening cloth areas arranged in a lateral direction, that is, into a plurality of discontinuous bonding surface areas, and the longitudinal size of those bonding surface areas are larger than the that of the fastening band 41. That is, in this embodiment, the first splicing part is a plurality of strip-shaped splicing structures, and a number of the strip-shaped splicing structures is set according to the actual application scene, which is more than five in this embodiment.

(28) During usage, the fastening band 41 separated from the fastening cloth 42 is adjusted in the longitudinal direction and then bound to a corresponding bonding surface area to adjust the spacing between the upper end edge and the lower end edge of the curtain 1, that is, the longitudinal size of the curtain 1 is adjusted to match the height requirements of the actual installation scene. And during the splicing process of the longitudinal size adjustment, the fastening band 41 is aligned in the bonding process by correspondingly aligning the upper edge or the lower edge of the fastening band 41 with the lower edge or the upper edge of the adhesive tape 43, which not only effectively improves the alignment rate, but also prevent the first splicing part and the second splicing part from being obliquely spliced based on the fact that fastening band 41 and the adhesive tape 43 cannot be bound. That is, in this embodiment, each adhesive tape 43 can provide alignment for two splice positions, meaning that in this embodiment, a number of provided splicing positions is at least twice that of the adhesive tapes. Of course, the adhesive tape 43 attached to the upper and lower edges of the fastening cloth 42 can only provide alignment for one of the splicing positions. For part of the areas that the longitudinal size of the bonding surface area is larger than that of the fastening band 41, that is, part of the areas that a distance between two adhesive tapes 43 is larger than the fastening band 41, these areas can also provide a partially continuously adjustable splicing positions, and for these splicing positions, the adhesive tape can be used for reference alignment.
