Referring to FIGS. 1 to 17, a foldable-width curtain according to the present invention is described. The foldable-width curtain comprises an upper rail assembly 1 and a light-shielding assembly 2. The upper rail assembly 1 is configured to be mounted on an external frame. The length of the upper rail assembly 1 is adjustable. The upper rail assembly 1 comprises a plurality of interconnected upper rail sections 11. The light-shielding assembly 2 is connected to the upper rail assembly 1. The light-shielding assembly 2 has a foldable structure. The light-shielding assembly 2 is capable of lateral folding. The light-shielding assembly 2 is also capable of vertical folding. The upper rail assembly 1 has a first use state and a second use state. In the first use state, the plurality of upper rail sections 11 are aligned in the same plane and connected to each other. In the second use state, the connection posture between the upper rail sections 11 changes. Specifically, the upper rail sections 11 are separated or folded.

It should be noted that the structure of the external frame is not unique and may be selected according to actual usage requirements. By way of example, the external frame may be a window frame or a door frame.

In one specific embodiment of the present invention, referring to FIGS. 1 to 8, the upper rail assembly 1 is positioned at the upper end of the curtain. The light-shielding assembly 2 is fixed to the upper rail assembly 1. The upper rail assembly 1 is mounted within a window frame or a door frame. The upper rail assembly 1 is formed by connecting a plurality of detachable or foldable upper rail sections 11. The connection between adjacent upper rail sections 11 includes, but is not limited to, a connector connection, an insertion connection, a mortise-and-tenon connection, or a hinge connection, in one or more forms.

In any practicable embodiment, referring to FIGS. 1 to 17, the upper rail section 11 has a cuboid shape, and both ends of the upper rail section 11 are provided with upper rail connecting holes 111 penetrating vertically. The upper rail connecting hole 111 is used for mounting an upper rail connector 12. Adjacent upper rail sections 11 are connected by the upper rail connector 12, and a plurality of upper rail sections 11 connected together form the upper rail assembly 1. The upper rail section 11 is provided with a fixing hole 112, a threaded sleeve 113, and a screw 114. The fixing hole 112 is used for installing the threaded sleeve 113, the threaded sleeve 113 is used for receiving the screw 114, and the screw 114 is used for fixing the light-shielding assembly 2. The upper rail connector 12 comprises a U-shaped slot strip 121. The U-shaped slot strip 121 laterally encloses the joint between two adjacent upper rail sections 11. The U-shaped slot strip 121 is provided with a threaded hole penetrating vertically, corresponding to the upper rail connecting hole 111. By passing a long screw through the threaded hole and the corresponding upper rail connecting hole 111, two adjacent upper rail sections 11 can be connected and fixed.

In one specific embodiment of the present invention, referring to FIGS. 1 to 17, the light-shielding assembly 2 comprises curtain panels 21 and connectors 22. The curtain panels 21 are provided in multiple pieces, and adjacent curtain panels 21 are connected to each other by the connectors 22. The light-shielding assembly 2 is configured to block light and to cover the upper rail assembly 1. The light-shielding assembly 2 may be fixed to the upper rail assembly 1 by one or more of bolts, air nails, adhesive, or insertion connection. When the light-shielding assembly 2 is fixed to the upper rail assembly 1, the portion located behind the upper rail assembly 1 serves as a curtain fabric, and the portion located in front of the upper rail assembly 1 serves as a curtain head. The light-shielding assembly 2 comprises a plurality of transversely separated curtain panels 21. The curtain panels 21 are interconnected by the connectors 22 and thereby can achieve lateral folding.

The structure of the connector 22 is not unique. The connector 22 includes, but is not limited to, flexible connectors and hinge connections. In any practicable embodiment, the connector 22 preferably has a flexible connector structure. When the number of curtain panels 21 is two, the light-shielding assembly 2 forms a “V”-shaped lateral fold. When the number of curtain panels 21 is three, the light-shielding assembly 2 forms an “N”-shaped lateral fold. When the number of curtain panels 21 is four, the light-shielding assembly 2 forms a “W”-shaped lateral fold. The light-shielding assembly 2 thus comprises short curtain fabrics and flexible connectors.

In some practicable embodiments, the curtain panel 21 is a curtain fabric that can be rolled up or folded in the vertical direction. Preferably, the curtain panel 21 is a bamboo curtain, in which a plurality of horizontally arranged bamboo strips are fixed by a plurality of vertically arranged woven cords. The curtain panel 21 is provided with a fixing hole 213, a mounting hole 214, and a cord-passing hole 215. The fixing hole 213 is configured to receive a fixing screw for securing the light-shielding assembly 2 to the upper rail assembly 1. The mounting hole 214 is configured for installing a mounting bracket assembly 3. The cord-passing hole 215 is configured for passing a pull cord therethrough.

In some practicable embodiments, the connector 22 is a flexible fabric, and the connector 22 connects adjacent curtain panels 21 by sewing or similar means, such that the adjacent curtain panels 21 achieve lateral folding about the connector 22 as an axis.

In one specific embodiment of the present invention, referring to FIGS. 1 to 17, the upper rail assembly 1 is connected and fixed to the external frame by a mounting bracket assembly 3. Specifically, the mounting bracket assembly 3 is mounted at the left and right edges of the upper rail assembly 1, and the upper rail assembly 1 is installed into a window frame or a door frame through the mounting bracket assembly 3.

In some practicable embodiments, the mounting bracket assembly 3 is arranged at both ends of the upper rail assembly 1. The mounting bracket assembly 3 may be one or more of a perforated mounting bracket 301 and a drill-free mounting bracket 302. The mounting bracket assembly 3 fixes the upper rail assembly 1 to the window frame or the door frame by means of tension support, screw fastening, or similar techniques. It should be noted that the specific structural composition of the mounting bracket assembly 3 belongs to the prior art and is not the focus of the present invention, and therefore will not be described in further detail herein.

In one specific embodiment of the present invention, referring to FIGS. 1 to 17, the foldable-width curtain further comprises a lifting control assembly 4. The lifting control assembly 4 is disposed below the upper rail assembly 1 and is configured to control the lifting of the light-shielding assembly 2 by one or more of manual lifting control, semi-automatic lifting control, or intelligent lifting control.

In some practicable embodiments, the lifting control assembly 4 is a semi-automatic lifting control structure. Specifically, the lifting control assembly 4 comprises a pull cord driving device 41, a positioner 42, positioning rings 43, and a pull cord 44. The pull cord driving device 41 is mounted below the upper rail assembly 1 and is connected to the pull cord 44. The pull cord driving device 41 controls the raising and lowering of the curtain by winding or unwinding the pull cord 44. The positioners 42 are distributed on both sides of the pull cord driving device 41 and mounted on the upper rail assembly 1, through which the pull cord 44 passes. In the naturally hanging state of the curtain, the positioner 42 applies a certain resistance to the retraction direction of the pull cord 44, thereby preventing the pull cord 44 from being retracted by the pull cord driving device 41 to some extent. The positioning rings 43 are arranged at uniform intervals on the surface of the light-shielding assembly 2. The positioning rings 43 may be attached to the curtain panels 21 by woven cords, fixing components, or directly by passing through the surface of the light-shielding assembly 2. The pull cord 44 passes through the positioning rings 43. When the curtain is lifted, the pull cord 44 is wound into the pull cord driving device 41, and the positioning rings 43 on the surface of the light-shielding assembly 2 are drawn closer together from bottom to top, thereby forming a number of folds in the light-shielding assembly 2. In any practicable embodiment, the positioning ring 43 has a closed-loop structure. The positioning ring 43 may be made of metal, plastic, or other suitable materials. The pull cord 44 is configured to control the lifting of the light-shielding assembly 2. One end of the pull cord 44 is wound within the pull cord driving device 41, which controls the winding and unwinding of the pull cord 44. The other end of the pull cord 44 passes through the positioner 42 and extends through the cord-passing hole 215 of the light-shielding assembly 2 from the front side to the rear side, and is finally fixed to the lowermost positioning ring 43, thereby enabling the pull cord 44 to control the lifting of the curtain.

In one specific embodiment of the present invention, referring to FIGS. 1 to 17, the foldable-width curtain further comprises a lower rail assembly 5. The lower rail assembly 5 is positioned at the bottom of the curtain and is connected to the light-shielding assembly 2. The lower rail assembly 5 increases the counterweight of the light-shielding assembly 2 so as to balance the tightening force of the lifting control assembly 4. By pushing upward or pulling downward on the lower rail assembly 5, the light-shielding assembly 2 can be driven to rise or lower accordingly.

In some practicable embodiments, the lower rail assembly 5 comprises multiple spliced lower rail sections 51. The length of the lower rail assembly 5 is adjustable. The lower rail assembly 5 has a first use state and a second use state. In the first use state, multiple lower rail sections 51 are in the same plane and adjacent lower rail sections 51 are connected in alignment. In the second use state, the connection posture between the lower rail sections 51 changes. Specifically, the lower rail assembly 5 is formed by connecting multiple detachable or foldable lower rail sections 51. The connection methods between the lower rail sections 51 include, but are not limited to, connector connections, insertion connections, mortise-and-tenon connections, and hinge connections.

In any practicable embodiment, adjacent lower rail sections 51 are connected by a lower rail connector 52.

The upper side of the lower rail section 51 is provided with a transversely penetrating strip-shaped slot 511 for mounting the light-shielding assembly 2. The rear side of the lower rail section 51 is provided with a positioning hole 513. The lower rail assembly 5 is equipped with a fixing screw 514, which passes through the positioning hole 513 to secure the light-shielding assembly 2. The lower side of the lower rail section 51 is provided with a transversely penetrating connector slot 512 for installing the lower rail connector 52.

The lower rail connector 52 is a strip-shaped metal plate, the surface of which is provided with screw holes 522 for installing connecting screws. The lower rail connector 52 is mounted within the connector slot 512 to connect adjacent lower rail sections 51. The strip-shaped metal plate is fixed to the lower rail sections 51 by connecting screws, thereby joining multiple small lower rail sections into an integral lower rail assembly 5.
