Description

Technical Field

[0001] This invention belongs to the field of sunshade product technology, specifically relating to a louvered sunshade awning. Background Technology

[0002] Venetian awnings not only provide shade, heat insulation, and rain protection, but also enrich the facade of buildings, beautify them, and change their appearance. They are durable, easy to clean, breathable, and fireproof. Traditional venetian awnings have exposed end plates at both ends of the louvers, with significant gaps between the end plates and the frame. During rain, water splashes onto the end plates or die-cast parts, easily entering the awning. Water also tends to accumulate at the joints between the end plates and other components, leading to rust and shortening the awning's lifespan. Furthermore, the end plates require self-tapping screws for fixing to the louvers, which is inconvenient, time-consuming, and makes it difficult to ensure a seamless fit between the end plates and the louvers, resulting in loosening and wobbling. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a louvered awning.

[0004] To achieve the above objectives, the invention employs the following technical measures: A louvered awning includes a frame and multiple louvers. Each louver has a louver end cap installed on both sides below its top cover. The louver end caps are hinged to the frame via a pivot. Two transmission rods are provided below each louver, and each louver end cap on the same side is hinged to the same transmission rod.

[0005] Preferably, the louver includes a bottom cover and a top cover, which are connected by a staggered interlocking method, forming an installation cavity between the bottom cover and the top cover. The two louver end caps are respectively installed at both ends of the installation cavity, and the rotating shaft extends from the end of the installation cavity.

[0006] Preferably, the top cover includes a covering surface, and the two ends of the covering surface are folded down to form a first fastening surface and a second fastening surface, respectively. The covering surface is a curved surface, a plane, or an inclined surface.

[0007] Preferably, the bottom cover includes a bottom plate, the two sides of which are folded upward to form a third fastening surface and a fourth fastening surface, the third fastening surface being connected to the bottom of the cover surface, and the second fastening surface being connected to the bottom plate.

[0008] Preferably, the bottom cover has mounting holes at both ends that communicate with the mounting cavity, the top end of the louvered end cover extends into the mounting cavity through the mounting holes, and the middle part of the louvered end cover abuts against the bottom surface of the bottom cover.

[0009] Preferably, the top of the louvered end cap is connected to an elastic card, and the elastic card is provided with a limiting buckle.

[0010] Preferably, the louvered end cap has a slot in the middle.

[0011] Preferably, the inner side of the louvered end cap is provided with a reinforcing rib skeleton, which is located at the edge of the louvered end cap.

[0012] Preferably, the rotating shaft includes a screw, on which a rotating shaft sleeve is mounted.

[0013] Preferably, the bottom of the louvered end cover has a pin hole for installing a pin, and the louvered end cover is connected to the transmission rod by the pin and limited by a loop pin.

[0014] The beneficial effects of this invention are as follows: Compared with the prior art, the louvered awning disclosed in this invention adopts the method of building the louver end caps inside, which reduces the corrosion of the louver end caps and their connections by rainwater, thus reducing oxidation or rust and effectively extending the service life of the louver end caps and even the louvered awning. Moreover, since the louver end caps are no longer set between the louvers and the frame, the gap between the louvers and the frame can be effectively reduced, which can not only effectively improve the light transmission and water seepage between the louvers and the frame, but also improve the fit between the louvers.

[0015] Furthermore, the louver end caps do not require screws to connect to the louvers, making them easy to install and remove. Even after multiple assembly, the louvers will not be damaged. There is no need to add reinforcing ribs to the louvers to accommodate the end caps, which reduces the weight of the louvers and makes the overall rotation of the louvers more flexible. In addition, the drive rod is located below the louvers, so the drive rod is not obviously exposed when the louvers are opened and closed. The overall canopy is more aesthetically pleasing and reduces unnecessary erosion of the drive rod and its connection points by rainwater. Attached Figure Description

[0020] Figures 1-6 This application discloses a louvered awning, comprising a frame 1 and multiple louvers 2. Each louver 2 has a louver end cap 3 installed on both sides below its top cover 21. The louvers 2 cover the louver end caps 3 at both ends. The louver end caps 3 are hinged to the frame 1 via pivots, thus mounting the louvers 2 onto the frame 1. Two transmission rods 4 are provided below each louver 2, and each louver end cap 3 on the same side is hinged to the same transmission rod 4. When the louvers 2 are open, they are parallel to each other. When the louvers 2 are closed, adjacent louvers 2 are connected end-to-end to form a sealed shading surface.

[0021] The rotating shaft includes a screw that passes through the louver 2. A rotating shaft sleeve is installed at the end of the screw. The rotating shaft sleeve is threadedly engaged with the screw. The outer wall of the rotating shaft sleeve is smooth. The louver 2 is mounted on the rotating shaft groove of the frame 1 through the rotating shaft sleeve.

[0022] See Figure 5The frame 1 is composed of four beams connected end to end. Two of the beams are provided with multiple pivot grooves. The pivots on both sides of the louvers 2 are respectively installed on the pivot grooves on both sides of the frame 1. Drainage grooves 11 are installed on the inner side of the four beams of the frame 1. The drainage grooves 11 are located below the gap between the louvers 2 and the frame 1. Columns are installed at the four corners of the frame 1. The columns are hollow inside and communicate with the drainage grooves 11.

[0023] In addition, a light groove 12 for installing light strips can be provided on one side of the drainage groove 11, and atomizers, heat sinks, etc. can also be installed. It can be set as needed and is not further limited.

[0024] For details, please refer to the following: Figure 4 In this embodiment, the louver 2 includes a bottom cover 22 and a top cover 21. The top cover 21 includes a covering surface 211. The two ends of the covering surface 211 are folded downward to form a first fastening surface 212 and a second fastening surface 213, respectively. The covering surface 211 can be a curved surface, a plane, or an inclined surface. Preferably, for better drainage and heat insulation, when the covering surface 211 is curved, an arched curved surface can be selected; when the covering surface 211 is inclined, a unidirectional inclined surface or a bidirectional inclined surface can be selected.

[0025] refer to Figures 2-3 The bottom cover 22 includes a bottom plate 221. The two sides of the bottom plate 221 are folded upward to form a third fastening surface 222 and a fourth fastening surface 223, respectively. The bottom cover 22 and the top cover 21 are connected by a staggered interlocking method, that is, the third fastening surface 222 is connected to the bottom of the covering surface 211, and the second fastening surface 213 is connected to the bottom plate 221, so that an installation cavity 23 is formed between the bottom cover 22 and the top cover 21. The bottom cover 22 has installation holes 24 at both ends that communicate with the installation cavity 23. The top end of the louvered end cover 3 extends into the installation cavity 23 through the installation hole 24. The two louvered end covers 3 are respectively installed at both ends of the installation cavity 23 through the installation hole 24. The rotating shaft extends out from the end of the installation cavity 23.

[0026] To secure the louvered end cap 23, one side of the louvered end cap 3 has a stepped structure. The top of the louvered end cap 3 is adapted to the mounting cavity 23. An elastic clip 32 is connected to the top of the louvered end cap 3. The elastic clip 32 is located on one side of the louvered end cap 3 and has a limiting buckle 33. When installing the louvered end cap 3, the elastic clip 32 is pressed towards the side of the louvered end cap 3, and the top of the louvered end cap 3 and the limiting buckle 33 are inserted into the mounting hole 24. The middle part of the louvered end cap 3 abuts against the mounting cavity 23. On the bottom surface of the bottom cover 22, a slot 34 is provided at the middle corner of the louver end cover 3. The slot 34 cooperates with the bottom cover 22 on one side of the mounting hole 24. When the elastic clip 32 is released, the elastic clip 32 elastically abuts against one side of the mounting hole 24, and the limiting buckle 33 limits and abuts against the upper end of the bottom cover 22, thereby limiting and installing the louver end cover 3 onto the louver 2. There is no need to use self-tapping screws for fixing. It can be repeatedly disassembled and reassembled, which is convenient and quick. It can also prevent the louver end cover 23 from becoming loose and shaking.

[0027] To ensure the structural strength of the louvered end cover 3, a reinforcing rib skeleton 35 is provided on the inner side of the louvered end cover 3, which is located at the edge of the inner side of the louvered end cover 3, and multiple reinforcing ribs are provided in the middle of the reinforcing rib skeleton 35.

[0028] In other embodiments, the louver 2 may be a single-layer structure, with a slot on both sides of the lower end of the louver 2 that is sealed around the perimeter and open at the bottom. The louver end cap 3 is installed on the slot by the elastic card 32 and the limiting buckle 33.

[0029] In other embodiments, the mounting cavity 23 may be filled with heat insulation materials, such as fiberglass, asbestos, rock wool, foam plastic, superfine glass wool, high silica cotton, aerogel felt, etc., which can enhance the heat insulation effect of the awning, and the heat insulation material is placed between the two louvered end caps 3.

[0030] refer to Figure 6 The bottom of the louvered end cap 3 has a pin hole, through which a pin 6 passes, connecting the louvered end cap 3 to the transmission rod 4. The end of the pin 6 has a through hole for inserting a U-shaped pin 7. The louvered end cap 3 and the transmission rod 4 are limited on the pin 6 by the U-shaped pin 7. The U-shaped pin 7 is made of a single elastic metal strip bent into shape. At least one side of the U-shaped pin 7 has a limiting protrusion. In use, pressing both sides of the U-shaped pin 7 causes its lower end to retract, inserting the U-shaped pin 7 into the through hole of the pin 6. Releasing the U-shaped pin 7 causes it to elastically return to its original position and lock into the through hole of the pin 6.

[0031] In summary, the louvered awning disclosed in this invention adopts an internal louver end cap design, which reduces the erosion caused by rainwater on the louver end cap and its connection points, thus reducing oxidation or rust and effectively extending the service life of the louver end cap and even the louvered awning itself. Moreover, since the louver end cap is no longer located between the louvers and the frame, the gap between the louvers and the frame can be effectively reduced, which not only effectively improves the light transmission and water seepage problems between the louvers and the frame, but also improves the fit between the louvers.

[0032] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the invention and should not be construed as limiting the specific implementation of the invention to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the inventive concept, and all such modifications and substitutions should be considered within the scope of protection of the invention.
