Description

Technical Field

[0001] The utility model relates to the technical field of blinds, in particular to an active blind bracket and a blind. Background Art

[0002] Venetian blinds, a common window shading device, consist of a blind bracket and a series of horizontally or vertically arranged blades mounted on the bracket. The amount of light entering can be adjusted by rotating the blades, thereby controlling the light intensity and privacy within the room. The blades are typically secured by clips, which are rotated to adjust the blade angle.

[0003] Currently, the leaf clamps are typically rotated by a lever mounted on the blinds support, driving a rotating member connected to the leaf clamps. Specifically, the lever and the rotating member are rotatably connected, allowing the rotating member to drive the leaf clamps to adjust the blade angles according to actual needs. However, most blinds support systems typically use a single lever to drive the rotating member, which is prone to breakage during daily use, resulting in poor overall balance and durability, and shortening the actual lifespan of the blinds.

[0033] In addition, numerous specific details are provided in the following detailed description to better illustrate the present disclosure. Those skilled in the art will appreciate that the present disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main points of the present disclosure.

[0034] like Figure 1 and Figure 2As shown, the embodiment of the present application provides an active bracket for a venetian blind, comprising: a bracket main body 100; a plurality of leaf clips 200 are arranged on the top of the bracket main body 100 for clamping the blades of the venetian blind, and a accommodating groove 110 is opened at the bottom of the bracket main body 100, and a rotating member 500 corresponding to the leaf clip 200 is arranged in the accommodating groove 110; a fixing member 510 is provided on the rotating member 500 for movably connecting the rotating member 500 with the leaf clip 200, and double-pull rod structures 300 are relatively arranged on both sides of the bottom of the rotating member 500; the two sides of the double-pull rod structure 300 are rotatably connected to the two sides of the rotating member 500 respectively, and a handle 400 is provided on the double-pull rod structure 300; wherein, when the handle 400 is moved, the handle 400 drives the double-pull rod structure 300 to move relative to the bracket main body 100, so that the rotating member 500 rotates, and the leaf clip 200 rotates relative to the bracket main body 100 under the drive of the rotating member 500.

[0035] Specifically, the active blinds support provided in this embodiment features a dual-tie rod structure 300 disposed on either side of a rotating member 500. It should be noted that when the handle 400 attached to the dual-tie rod structure 300 is moved, the handle 400 can drive the dual-tie rod structure 300 to move relative to the support body 100. The two tie rods on the dual-tie rod structure 300 move in opposite directions, thereby driving the rotating member 500 to rotate, which in turn drives the attached leaf clip 200 to rotate, thereby adjusting the angle of the blinds. The dual-tie rod structure 300 effectively shares the load, reducing the risk of damage to a single tie rod due to excessive stress. Furthermore, the dual-tie rod structure 300 disposed on either side of the rotating member 500 ensures a more balanced overall structure, evenly distributing force when rotating the rotating member 500, thereby enhancing the balance and durability of the active blinds support. The active blinds support in this embodiment features a simple overall structure, making it easy to install and disassemble, effectively improving the efficiency of both initial installation and subsequent maintenance and cleaning.

[0036] In some embodiments, the double-rod structure 300 includes a first rod 310 and a second rod 320 arranged in parallel; and the first rod 310 and the second rod 320 are both accommodated in the accommodating groove 110; wherein, when the handle 400 is moved, the first rod 310 and the second rod 320 move in opposite directions, so that the rotating member 500 can rotate driven by the first rod 310 and the second rod 320.

[0037] The double-pull rod structure 300 in this embodiment includes a first pull rod 310 and a second pull rod 320 that are parallel to each other, and the first pull rod 310 and the second pull rod 320 move in opposite directions, thereby driving the rotating member 500 to rotate. It should be noted that the first pull rod 310 and the second pull rod 320 in this embodiment are both accommodated in the receiving groove 110 at the bottom of the bracket body 100 and do not extend out of the receiving groove 110. That is, the first pull rod 310 and the second pull rod 320 are surrounded by the receiving groove 110, preventing the first pull rod 310 and the second pull rod 320 from breaking when exposed outside the bracket body 100, further ensuring the durability of the double-pull rod structure 300.

[0038] In some embodiments, a connecting member 600 is further included; the connecting member 600 is arranged corresponding to the rotating member 500, and the top surface of the connecting member 600 is fixedly connected to the bottom surface of the rotating member 500, and the two ends of the bottom surface of the connecting member 600 are rotatably connected to the top surface of the first pull rod 310 and the top surface of the second pull rod 320 respectively.

[0039] In this embodiment, a connector 600 is further provided between the rotating member 500 and the double-tie rod structure 300. Specifically, the connector 600 is provided corresponding to the rotating member 500. The center of the top surface of the connector 600 is fixed to the center of the bottom of the rotating member 500. The two ends of the bottom surface of the connector 600 are respectively located on the first tie rod 310 and the second tie rod 320, and are rotatably connected to the top surfaces of the first tie rod 310 and the second tie rod 320. It should be noted that when the first tie rod 310 and the second tie rod 320 move in opposite directions, they can drive the connector 600 to rotate, thereby rotating the rotating member 500 fixed to the connector 600. It should be noted that the coordinated arrangement of multiple connectors 600 between the first tie rod 310 and the second tie rod 320 makes the overall structure more stable and firm, less likely to loosen, and effectively enhances the durability of the active blind bracket.

[0040] In some embodiments, a gasket 700 is provided on the double-pull rod structure 300 ; one end of the gasket 700 is rotatably connected to the first pull rod 310 , and the other end is rotatably connected to the handle 400 .

[0041] In this embodiment, the gasket 700 is disposed within the receiving groove 110, and one end of the gasket 700 is rotatably connected to the first pull rod 310, and the other end is rotatably connected to a corresponding position of the handle 400. The handle 400 has one end disposed on the second pull rod 320 and the other end extending toward the first pull rod 310 and out of the bracket body 100. Specifically, when the blades are in a closed state, the connection position between the gasket 700 and the handle 400 is located between the first pull rod 310 and the second pull rod 320. At this time, the gasket 700 tilts from the end fixed to the first pull rod 310 toward the second pull rod 320; when the handle 400 moves, the gasket 700 gradually rotates to a state parallel to the first pull rod 310. When the connection position between the gasket 700 and the handle 400 is located directly above the first pull rod 310, the gasket 700 as a whole is parallel to the first pull rod 310; when the blades are in a fully open and closed state, the gasket 700 tilts from the end fixed to the first pull rod 310 toward the outside of the bracket body 100. That is, an openable and closable structure is formed between the gasket 700, the first pull rod 310 and the handle 400. When the handle 400 is operated, the handle 400 can be effectively maintained at the target position, ensuring the normal use requirements of the blinds and preventing the blades from moving under the influence of gravity, thereby affecting the actual shading effect.

[0042] In some embodiments, the number of the fixing members 510 is at least two.

[0043] It should be noted that the rotating member 500 of this embodiment is provided with at least two fixing members 510. The fixing members 510 extend upward from the bottom of the rotating member 500 through the bracket body 100 and into the page clip 200 to secure the page clip 200 and the rotating member 500, thereby movably connecting the rotating member 500 and the page clip 200. In other words, under the fixing action of the fixing members 510, the rotating member 500 and the page clip 200 can rotate relative to each other simultaneously. When the rotating member 500 is rotated by an external force, the page clip 200 can rotate accordingly. With the action of at least two fixing members 510, the fixing effect between the page clip 200 and the rotating member 500 can be effectively guaranteed, preventing the rotating member 500 from loosening after multiple rotations during subsequent use, thereby preventing the page clip 200 from falling.

[0044] It should also be noted that the fixing member 510 in this embodiment is preferably a screw, which can reduce production costs. The material of the bracket body 100 is preferably aluminum alloy, and screw fixing holes are provided at the upper and lower ends of the bracket body 100 for fixing the bracket body 100 to the wall. In addition, the rotating member 500 in this embodiment has a cylindrical structure. When the first pull rod 310 and the first pull rod 320 move in opposite directions, the rotating member 500 can rotate along its axis.

[0045] In some embodiments, a groove 120 is formed on one side of the bracket body 100 to limit the movement position of the handle 400.

[0046] In this embodiment, the bracket body 100 has a groove 120 at a position corresponding to the handle 400, with one end of the handle 400 extending out of the groove 120. Specifically, when the handle 400 is located in the middle of the groove 120, the blades are in a closed state; as the handle 400 is gradually moved, the blades tilt synchronously; and when the handle 400 contacts one end of the groove 120, the blades are in a fully open state, thereby limiting the maximum opening and closing of the blades.

[0047] In some embodiments, the handle 400 includes a pull handle 410 and a pull head 420; one end of the pull handle 410 is rotatably connected to the side of the double pull rod structure 300 away from the pull head 420, and the other end of the pull handle 410 extends out of the bracket body 100 to form a bending structure between the pull head 420.

[0048] In this embodiment, one end of the handle 410 is rotatably connected to the second pull rod 320, and the other end extends toward the first pull rod 310 and out of the bracket body 100 from the groove 120. A bend is formed between the pull head 420 and the end of the handle 410 that extends out of the bracket body 100. During actual use, the user can place their fingers on the bend and move the pull head 420 according to specific needs. Compared to traditional handles 400 without a pull head 420, the push-pull process is more labor-saving and convenient to operate, and the handle 400 can be moved with a single finger. The handle 400 is preferably made of plastic, which can effectively reduce production costs.

[0049] It should also be noted that the handle 410 of this embodiment also has a bent structure. When the leaves are in the closed state, the distance between the end of the handle 410 extending from the bracket body 100 and the bracket body 100 is smaller than the distance between the end of the handle 410 extending from the bracket body 100 and the bracket body 100 of a traditional straight-line handle 410. This allows the slider 420 to fit more closely with the side of the bracket body 100. In other words, the overall structure is more compact, takes up less space, and can meet the needs of users with limited installation space.

[0050] In some embodiments, the slider 420 is an arc-shaped sheet structure.

[0051] In this embodiment, the slider 420 is an arc-shaped sheet structure, which is suitable for users to place their fingers, and the curvature of the arc surface matches the curvature of the fingertips, making the user's operation more comfortable.

[0052] In some embodiments, the leaf clip 200 includes a first clip 210, a second clip 220 and a bottom plate 230; the first clip 210, the bottom plate 230 and the second clip 220 are sequentially arranged to form a cavity for placing the leaf, and notches 231 with opposite opening directions are arranged at both ends of the bottom plate.

[0053] In this embodiment, a first clip 210, a base plate 230, and a second clip 220 are used to enclose a cavity capable of accommodating a blade. Furthermore, notches 231 with openings in opposite directions are provided on either end of the base plate 230. After the blade is installed in the cavity, its upper and lower ends are positioned above the corresponding notches 231. Therefore, when a user needs to replace a blade, they can simply move the blade from the notches 231 on the base plate and remove it from the cavity, allowing for the ability to replace the desired blade at any time, providing greater flexibility during use.

[0054] In some embodiments, when the blades are in the closed state, the first clip 210 and the second clip 220 extend into adjacent notches 231 .

[0055] In order to ensure the light-shielding property of the blinds, the first clip 210 and the second clip 220 of this embodiment can extend into the adjacent notches 231 to ensure that sunlight cannot pass through between adjacent leaf clips 200 when the blades are closed.

[0056] In some embodiments, the first clip 210 includes a first clamping plate 211 and a first side plate 212, and the second clip 220 includes a second clamping plate 221 and a second side plate 222; the first clamping plate 211 and the second clamping plate 221 are parallel to each other and are used to clamp the upper and lower ends of the blade; the first side plate 212 and the second side plate 222 are parallel to each other and are used to fix the left and right sides of the blade.

[0057] It should be noted that the first and second clipping plates 211, 221 of this embodiment are parallel to each other and are located at the upper and lower ends of the leaf clip 200, respectively. The first and second side plates 212, 222 are also parallel to each other and are located at the left and right sides of the leaf clip 200, respectively. Thus, the left and right sides of the leaf can be fixed by the parallel side plates, and the clipping plates at the upper and lower ends further enhance the fixing effect of the leaf, preventing the leaf from falling out of the cavity during use, and improving overall safety.

[0058] In the second aspect, an embodiment of the present application provides a Venetian blind, comprising: any of the above-mentioned Venetian blind active brackets, a Venetian blind driven bracket and blades matching the Venetian blind active bracket; and the two ends of the blades are respectively arranged on the Venetian blind active bracket and the Venetian blind driven bracket.

[0059] Specifically, the Venetian blinds driven bracket in this embodiment includes a driven bracket body, driven leaf clips, and a driven rotating member. The driven leaf clips are mounted on the top surface of the driven bracket body, and their number matches the number of blades. A receiving cavity is provided at the bottom of the driven bracket body. The driven rotating member is located within the receiving cavity and is movably connected to the driven leaf clips. When the handle on the Venetian blinds active bracket is moved, the leaf clips on the active bracket rotate the blades, and the driven leaf clips on the driven bracket rotate accordingly. That is, the two sides of the blades are mounted on the active bracket and the driven bracket, respectively, and the leaf clips provided on the brackets secure the blades.
