[0002] Office break chair: also known as a "leisure office chair," "conference chair," or "rest area chair." Its primary design purpose is not to allow users to maintain a standard sitting posture for extended periods of desk work, but rather to provide a comfortable experience for short breaks, relaxation, informal conversations, reading, or waiting.

[0003] While existing office break chairs largely meet users' basic needs, they still reveal some significant shortcomings in actual use. For example, to facilitate user rest, existing office break chairs are often designed with adjustable angles, or even unfold into a reclining shape, allowing users to fully relax during work breaks. However, a common problem with commercially available office break chairs is that they cannot fully unfold to a horizontal position. This deficiency prevents users from lying flat, thus affecting the quality of rest to some extent. In addition, the area of ​​office break chairs is often fixed and relatively small. This design results in lower seat comfort, and prolonged use can easily cause user discomfort, further impacting the effectiveness of rest. Therefore, although existing office break chairs can meet the needs to a certain extent, these shortcomings still urgently need to be improved. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3As shown, this utility model provides an office lounge chair with an extended folding function, including a seat panel 1 and a backrest panel 2. Mounting blocks 6 are provided on both sides of one end of the seat panel 1, and connecting blocks 7 are provided on both sides of one end of the backrest panel 2. The connecting blocks 7 are located on one side of the mounting blocks 6 and are rotatably connected to the mounting blocks 6. Both the backrest panel 2 and the seat panel 1 are hollow structures. An unfolding structure is provided on both sides of the backrest panel 2 and the seat panel 1. The unfolding structure includes double-threaded screws 10, which are rotatably installed on both sides inside the backrest panel 2 and the seat panel 1. The two double-threaded screws 10 are interconnected by a transmission sprocket and a transmission chain. A groove is provided in the middle of one end of both the backrest panel 2 and the seat panel 1. An adjusting rod 11 is inserted into the interior of the backrest 2 and the seat 1. One end of the adjusting rod 11 is inserted into the interior of the backrest 2 and the seat 1. The adjusting rod 11 is connected to an adjacent double-threaded screw 10. The adjusting rod 11 is connected to the double-threaded screw 10 through a bevel gear and a reversing gear. An unfolding plate 9 is inserted into the interior of both sides of the backrest 2 and the seat 1. Both ends of one side of the unfolding plate 9 are provided with threaded holes that cooperate with the double-threaded screw 10. One end of the unfolding plate 9 is inserted into the outside of the backrest 2 and the seat 1 and is equipped with an installation strip 3. Folding legs 5 are installed at both ends of one side of the seat 1, the backrest 2 and the installation strip 3. Armrest rails 4 are fixedly installed on the surface of the installation strip 3 on both sides of the seat 1.

[0024] In this embodiment, the user manually rotates one end of the adjusting rod 11. This rotation is transmitted to the other end of the adjusting rod 11 through the internal mechanical transmission structure. This end is connected to a precision gear system, including a bevel gear and a reversing gear. The bevel gear design makes the force transmission smoother, while the reversing gear changes the direction of the force, ensuring that the power can be efficiently transmitted to the adjacent double-threaded screw 10. After being driven, this double-threaded screw 10 begins to rotate. At the same time, the other double-threaded screw 10 connected to it also achieves synchronous rotation under the cooperative action of the transmission sprocket and transmission chain. The precise cooperation of the transmission sprocket and transmission chain ensures the synchronicity and stability of the rotation of the two double-threaded screws 10.

[0025] As the double-threaded screw 10 rotates, the unfolding plates 9 on both sides of the seat plate 1 and backrest plate 2 begin to move under the action of the threaded holes. The design of the threaded holes allows the unfolding plates 9 to move smoothly and precisely to the outside of the seat plate 1 and backrest plate 2 along the threaded trajectory of the screw. This process not only ensures the smoothness of the unfolding action but also ensures the stability of the entire device after unfolding. Through this ingenious design, the entire device can unfold smoothly, thus significantly expanding the usable area. This not only provides users with more spacious space but also greatly enhances the comfort of use, creating a more pleasant resting environment. Whether used for daily rest or temporary relaxation, this design greatly enhances the user experience and meets people's pursuit of a high-quality living environment.

[0026] Both the backrest panel 2 and the seat panel 1 are equipped with insulating pads. These pads can be designed to fold inwards, allowing them to unfold and lay flat on the surface of the unfolding panel 9 when it is fully extended. This design not only facilitates the storage and carrying of the pads but also provides a more comfortable and convenient experience, ensuring that the user on the unfolding panel 9 enjoys warm and soft support.

[0027] like Figures 2 to 5 As shown, this utility model provides an office lounge chair with an extended folding function. An adjustment structure is provided between the backrest panel 2 and the seat panel 1. The adjustment structure includes a mounting sleeve 12, which is fixedly installed on one side of a mounting block 6. A through hole is formed on the surface of the mounting block 6, and a connecting rod 15 is movably inserted through the through hole. Slide grooves 19 are formed on both sides of the surface of the connecting rod 15, and sliders are provided on both sides of the inner wall of the through hole. The sliders are slidably connected to the slide grooves 19. A limiting groove 14 is formed on the surface of the mounting block 6, and a limiting block 17 connected to a connecting block 7 is movably inserted through the limiting groove 14. A fixing tube 8 is fixedly installed between the two connecting blocks 7. One side of the connecting rod 15... The connecting rod 15 is movably inserted inside the fixed tube 8 and is equipped with a movable block 21. The surface of the connecting rod 15 is fitted with a tension spring 20 connected to the movable block 21. The other end of the connecting rod 15 is equipped with a locking gear 16. One end of the locking gear 16 is movably inserted outside the mounting sleeve 12 and is equipped with a push block 18. One end of the mounting sleeve 12 is provided with a locking gear ring 13 that engages with the locking gear 16. One side of each of the two movable blocks 21 is fixedly equipped with a rack 22. The two racks 22 are staggered. The fixed tube 8 is rotatably installed with a rotating rod 23. The surface of the rotating rod 23 is fixedly fitted with a meshing gear 24, which meshes with the rack 22.

[0028] In this embodiment, when the user needs to adjust the angle of the backrest 2, he / she first pushes the push block 18 located on one side of the backrest 2. This push action will be immediately transmitted to the locking gear 16 and the connecting rod 15 connected to it, so that they start to move together. Specifically, after the connecting rod 15 is subjected to the force of the push block 18, it will drive the movable block 21 connected to it to move together. During this series of movements, the tension spring 20 is stretched, and the movable block 21 further drives the rack 22 to move linearly. The rack 22 drives the rack on the other side to start moving through the meshing action of its teeth and the gear. During the movement of the rack on the other side, it will drive the movable block 21, the connecting rod 15 and the locking gear 16 on its corresponding side to move accordingly.

[0029] This linkage mechanism ultimately disengages the locking gears 16 on both sides from the locking gear rings 13, allowing the connecting rod 15 to rotate freely inside the mounting block 6 and the mounting sleeve 12. At this point, the user can manually rotate the backrest plate 2, which will cause the connecting block 7 and the connecting rod 15 to rotate together. The rotation of the connecting rod 15 will further drive the locking gears 16 to rotate accordingly.

[0030] During the entire rotation process, the limiting groove 14 and the limiting block 17 play a key role. They together limit the rotation range of the backrest 2, ensuring that it can be adjusted within a safe range. When the limiting block 17 moves to one end of the limiting groove 14, the seat plate 1 and the backrest 2 will be in a straight line, reaching the maximum unfolded state. At this time, the user can release the push block 18, and the connecting rods 15 on both sides will automatically return to the initial position under the restoring force of the tension spring 20. This process causes the locking gears 16 on both sides to re-engage with the locking gear rings 13, thereby effectively limiting the angle of the backrest 2.

[0031] This ingenious design not only facilitates the unfolding and folding of the entire device, but also greatly enhances the user's comfort. In particular, when the user needs to lie down to rest, the angle adjustment function of the backrest 2 is especially important, providing support that conforms more closely to the curves of the human body, allowing the user to better relax and enjoy a high-quality rest experience.
