Description

Technical Field

[0001] This utility model relates to a leisure chair, specifically a leisure chair with adjustable functions. Background Art

[0002] A lounge chair is a chair that people use to enjoy their leisure time. Unlike dining chairs and office chairs, these chairs are not formal but have a touch of personality and can bring both visual and physical comfort.

[0003] Fujian Huian Zhenhui Furniture Co., Ltd. disclosed a leisure chair in its utility model patent with authorization announcement number CN218683121U. The chair includes a seat and a backrest fixedly connected to the seat. The seat includes diagonal support legs, connecting rods, straight support legs, and a seat plate. The seat plate is horizontally arranged. There are two of each of the diagonal support legs, connecting rods, and straight support legs, which are distributed along the length of the seat plate. The connecting rod is located between the diagonal support legs and the straight support legs, and one end of the connecting rod is fixedly connected to the diagonal support legs. This device only uses an arc-shaped back panel and a soft padding wrapped around the arc-shaped back panel to improve the fit of the user's back. The structure is relatively simple, not convenient for flexible adjustment to various usage states, and difficult to adapt to different groups of people.

[0024] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0025] Example: This utility model provides a lounge chair with an adjustable function, see reference. Figures 1 to 9As shown, the device includes a seat frame 1, a crossbeam 2, a backrest frame 3, a seat cushion 4, a backrest 5, and a limiting structure. The seat frame 1 has crossbeams 2 spaced apart, and seat cushions 4 are placed on the crossbeams 2. The backrest frame 3 is rotatably connected to the rear of the seat frame 1, and the backrest 5 is located on the front of the backrest frame 3. The upper side of the crossbeams 2 and both the front and rear sides of the backrest frame 3 are provided with rough surfaces 100. The seat cushions 4 and backrest 5 are fixed by fitting against these rough surfaces 100, facilitating easy disassembly and placement of the seat cushions 4 and backrest 5, and allowing for flexible switching and adjustment of the backrest frame 3 and backrest 5's usage status, making it convenient to use. A limiting structure is provided at the rear of the seat frame 1 to support the backrest frame 3. The structure allows the backrest frame 3 to flip forward to be flush with the crossbeam 2, facilitating easy adjustment of the backrest 5's height. This allows the backrest 5 to flip backward and wrap around the limiting structure, thus flexibly reducing the usable height of the backrest 5. Flipping the limiting structure downward to contact the ground provides further support for the backrest frame 3 and the backrest 5. The limiting structure includes a rotating rod 6, a connecting rod 7, a limiting rod 8, and an adjusting component. The rotating rod 6 is rotatably connected to the rear side of the seat frame 1 near the connection point of the backrest frame 3. Connecting rods 7 are spaced apart in the middle of the rotating rod 6. Limiting rods 8 are connected between the ends of each connecting rod 7. An adjusting component is provided between the limiting rod 8 and the seat frame 1.

[0026] See Figures 3 to 9 As shown, the adjusting component includes a pull rod 9, an insert rod 10, an elastic element 11, and a fixing sleeve 12. Movable cavities 60 are respectively opened at both ends of the rotating rod 6, and the pull rod 9, which can be moved and adjusted, is inserted into the movable cavity 60. The other end of the pull rod 9 is connected to the insert rod 10. Adjusting cavities 80 are respectively opened at both ends of the limiting rod 8, and the insert rod 10 is slidably inserted into the adjusting cavity 80. An elastic element 11, which is a compression spring, is connected between the inner side of the adjusting cavity 80 and the insert rod 10 to provide outward pressing force to the insert rod 10 connected thereto, so that the outer end of the insert rod 10 can be firmly inserted into the fixing sleeve 12. A fixing sleeve 12 is provided on the upper rear side of the seat frame 1, and the outer end of the insert rod 10 is movably inserted into the fixing sleeve 12. Combining the pull rod 9 and the insert rod 10 can form an I-shaped structure, which is beneficial to improving the structural strength of the pull rod 9 and the insert rod 10, thereby providing stable support for the backrest frame 3 and the backrest 5.

[0027] This lounge chair allows users to adjust the angle and position of the backrest frame 3 and backrest 5 according to their needs, thus helping them achieve optimal comfort for rest. Specifically, when the insert rod 10 is inserted into the fixing sleeve 12, the backrest frame 3 and backrest 5 can be flipped open (e.g., Figure 1 , Figure 4 and Figure 6 As shown); when the backrest 3 is flipped forward until it is flush with the crossbeam 2 (as shown); Figure 2 and Figure 5As shown), the backrest 5 is made of flexible filling material and can be folded back onto the limiting structure. When it is necessary to adjust the angle of the backrest frame 3 and the backrest 5 to tilt backward, first pull the pull rods 9 on both sides to retract them to the middle so that the insert rod 10 can be disengaged from the fixing sleeve 12. Then, the connecting rod 7, limiting rod 8, pull rod 9, insert rod 10 and elastic element 11 can be flipped downward around the rotating rod 6 to contact the ground. Subsequently, the backrest frame 3 and the backrest 5 can be flipped backward simultaneously to adjust a certain range so that the lower part of the rear side of the backrest frame 3 can abut against the rotating rod 6 (as shown). Figure 7 and Figure 8 As shown), the rotating rod 6 can then provide a limiting support for the backrest frame 3 that flips backward; thus, it is beneficial for the user to flexibly adjust the use of this lounge chair, thereby providing the user with a variety of comfortable rest options.
