[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.
[0031] A segmented, flexible curtain track includes several segmented tracks 100 and a connecting structure for fixing adjacent segmented tracks 100 together. The segmented tracks 100 can be of equal or unequal length. By sequentially assembling several segmented tracks 100 of equal or unequal length through the connecting structure, a curtain track of any length can be formed. Figure 1 and Figure 8 As shown.
[0032] The segmented track 100 has a sheet-like structure, allowing it to be bent along its length, thus adapting to different installation environments and enabling both straight and bent applications. Figure 9 A diagram showing the curve of the curtain track;
[0033] The segmented track 100 has an upper rail 1 that protrudes to both sides along its width at the upper end, and a lower rail 2 that protrudes to both sides along its width at the lower end, forming an "I"-shaped structure. Figures 2-4 As shown.
[0034] The docking structure includes a docking insert 3 protruding from one end of the segmented track 100, a docking slot 4 recessed at the other end of the segmented track 100, an elastic latch 5 elastically disposed on the docking insert 3, and a latching groove 6 recessed in the docking slot 4 to hook with the elastic latch 5. The docking insert 3 is integrally formed with the segmented track 100. When assembling two adjacent segmented tracks 100, the docking insert 3 of one segmented track 100 is inserted into the docking slot 4 of the other segmented track 100. During the insertion process, the elastic latch 5 on the docking insert 3 can engage with the latching groove 6 of its corresponding docking slot 4, thereby fixing the two segmented tracks 100 together. Figure 6 and Figure 7 As shown.
[0035] In some examples, such as Figure 2 and Figure 3 As shown, the docking structure also includes a positioning protrusion 7 protruding from one end of the segmented track 100 and a positioning groove 8 recessed at the other end of the segmented track 100 for the positioning protrusion 7 to be inserted. The end of the positioning protrusion 7 facing away from the segmented track 100 is tapered, which can provide guidance for its insertion process. In the process of assembling the two segmented tracks 100, the two segmented tracks 100 can be aligned in the horizontal and vertical directions by the cooperation of the positioning protrusion 7 and the positioning groove 8. Then, the two segmented tracks 100 can be fixed by the elastic latch 5 and the latch groove 6.
[0036] In some examples, such as Figure 2 As shown, the mating insert 3 forms a through groove 301, the elastic buckle 5 is located in the through groove 301 and one end of the elastic buckle 5 is fixed to the groove wall of the through groove 301, and the other end is suspended and protrudes to form a fastening part 501. The structure of one end fixed and the other end suspended allows the elastic buckle 5 to have a certain elasticity. The upper rail 1 and the lower rail 2 have recesses on the side that are close to each other. The openings of the two recesses are opposite to each other to form the above-mentioned mating slot 4. When the curtain track bends, the mating insert 3 confined in the mating slot 4 will not come out. Preferably, in order to ensure the structural strength after bending, the bending direction of the curtain track is away from the protruding direction of the fastening part 501, thereby improving the connection strength between the fastening part 501 and the buckle groove 6.
[0037] In some examples, such as Figure 1 As shown, the curtain track also includes multiple track mounting brackets 9, which are spaced apart along the length of the curtain track. Each track mounting bracket 9 has a groove 901 that mates with the upper rail 1. The curtain track can be installed at any position on the wall using the track mounting brackets 9.
[0038] In some examples, such as Figure 1As shown, the curtain track also includes multiple hanging rollers 10 arranged sequentially along the length of the curtain track. Each hanging roller 10 includes rollers 1001 that cooperate with the lower track 2 and hanging rings 1002 for hanging the curtain. Each hanging roller 10 has two sets of rollers 1001 connected by mounting ears. The hanging rings 1002 are rotatably mounted on the lower end of the mounting ears by pins. The rotation axis of the pins intersects with the rotation axis of the hanging rings 1002. The rollers 1001 reciprocate along the length of the curtain track to open or close the curtain.
[0039] In some examples, such as Figure 1 As shown, both ends of the curtain track are adjustable and equipped with end caps 11. The shape of the end caps 11 matches the shape of the curtain track. They are fitted onto the ends of the curtain track, and a set screw is installed on the end caps 11. The set screw passes through the end caps 11 and its head abuts against the curtain track. By adjusting the abutment position, the end caps 11 can be fixed at different positions on the curtain track, thereby achieving precise adjustment of the length of the curtain track.
[0040] In some examples, the segmented track 100 is extruded, a molding method that has a short cycle time, high dimensional accuracy, good surface quality and excellent mechanical properties, and has different cross-sectional shapes along its length.
[0041] In some examples, such as Figure 2 As shown, the end of the mating insert 3 that is away from the segment track 100 where it is located is its insertion end. The insertion end has a guide slope 302, which facilitates the insertion of the mating insert 3 into the mating slot 4.
[0042] In some examples, such as Figure 2 As shown, the fastening part 501 includes an abutting section 5011 for abutting against the groove wall of the locking groove 6 and a guide section 5012 connected to the abutting section 5011. The guide section 5012 is located at the front end of the abutting section 5011 along the insertion direction and is inclined. The guide section 5012 facilitates the fastening part 501 to be inserted into the locking groove 6.
[0043] In some examples, such as Figure 2 and Figure 3 As shown, there are multiple positioning protrusions 7 and positioning grooves 8, and they correspond one-to-one. Each positioning protrusion 7 is inserted into its corresponding positioning groove 8. In this embodiment, the multiple positioning protrusions 7 and multiple positioning grooves 8 are divided into two groups and are distributed vertically. One group of positioning protrusions 7 (or positioning grooves 8) is located on the upper rail 1, and the other group of positioning protrusions 7 (or positioning grooves 8) is located on the lower rail 2. There are also multiple positioning protrusions 7 (or positioning grooves 8) in each group.
[0044] Working principle:
[0045] During installation, the two segmented tracks 100 are first aligned horizontally and vertically using the positioning protrusion 7 and positioning groove 8. Simultaneously, the mating insert 3 of one segmented track 100 is inserted into the mating slot 4 of the other segmented track 100. During the insertion process, the elastic latch 5 on the mating insert 3 can be engaged into the latch groove 6 of its corresponding mating slot 4, thereby fixing the two segmented tracks 100 together. Similarly, multiple segmented tracks 100 of equal or unequal length can be connected to form a curtain track of a predetermined length. Then, end caps 11 are fitted onto both ends of the curtain track, and the end caps 11 are fixed at different positions of the curtain track with set screws to obtain a curtain track of precise length. Finally, the assembled curtain track is fixed in the required position using the track mounting bracket 9. The segmented track 100, with its sheet-like structure, can be bent or straight, thus adapting to different installation environments.
[0046] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
