Description

Technical Field

[0001] This application relates to the technical field of furniture, and in particular to a lounge chair that can be converted into multiple positions. Background Technology

[0002] In daily life, lounge chairs are commonly used furniture for rest and relaxation, and their design rationality and comfort are of paramount importance. However, most lounge chairs on the market today have relatively fixed shapes, mainly consisting of two simple forms: those without backrests and those with backrests. This single-form design makes it difficult to meet the diverse seating posture needs of different users in various scenarios.

[0003] For example, when reading outdoors, users would like a lounge chair with an adjustable leg rest to relieve leg fatigue; for short breaks, it needs to be adjusted to a reclining position; and when chatting with friends, the leg rest needs to be folded down while the backrest remains for easy interaction.

[0004] Different scenarios require different postures when using a lounge chair, but traditional lounge chairs, due to their fixed shape, have significant limitations in terms of comfort, adaptability, and functionality, making it difficult to meet the diverse seating needs of different users. Therefore, there is an urgent need for a lounge chair that can flexibly adapt to multiple postures to solve these problems. Utility Model Content

[0005] In order to provide a lounge chair that can flexibly change posture according to usage needs, this application provides a lounge chair that can change to multiple postures, which is highly adaptable and can meet the needs of different users for seats in various postures.

[0006] This application provides a lounge chair that can be converted into multiple postures, using the following technical solution:

[0007] A lounge chair capable of changing multiple postures includes a fixed base, adjustable plates, and a locking structure. The fixed base is supported on the ground, and two adjustable plates are provided, each rotatably connected to opposite ends of the fixed base. The locking structure is installed at the connection between the adjustable plates and the fixed base, and is used to lock the rotation angle of the adjustable plates to achieve posture changes.

[0008] By adopting the above technical solution, the fixed base provides stable support for the lounge chair, the adjustable plate can change shape by rotating, and the user can adjust the adjustable plate to a suitable position by locking the angle of the adjustable plate through the locking structure. The operation is simple and meets the diverse usage needs of users in different scenarios.

[0009] Optionally, the fixed base includes a base grid plate, the base grid plate has an inverted U-shaped structure, and there are multiple base grid plates. The multiple base grid plates are evenly spaced and a rotating shaft passes through them, and a grid gap is formed between adjacent base grid plates; the adjustable plate is inserted into the grid gap and connected to the rotating shaft.

[0010] By adopting the above technical solution, the inverted U-shaped design enhances the mechanical stability of the fixed rod base under pressure, preventing the lounge chair from tilting or deforming due to uneven force; the evenly spaced base grid provides installation space for the adjustable plate, while saving materials, reducing the overall weight of the lounge chair, and making it convenient to move and transport.

[0011] Optionally, the adjustable plate includes a rotating grid plate, and the rotating grid plate has multiple rotating grid plates arranged in parallel. The rotating grid plates are inserted into the grid gaps. The ends of the rotating grid plates are fixedly connected to a rotating shaft, and the multiple rotating grid plates rotate synchronously with the rotating shaft.

[0012] By adopting the above technical solution, rotating one of the rotating grid plates can drive the entire adjustable plate to rotate synchronously, completing the angle adjustment. It is not necessary to adjust each rotating grid plate separately, making the adjustment process of the adjustable plate more convenient. At the same time, the synchronous rotation design avoids structural distortion or damage caused by asynchronous rotation of each rotating grid plate, extends the service life of the adjustable plate, and improves the overall reliability and durability of the lounge chair.

[0013] Optionally, the locking structure is located at the connection between the rotating grid plate and the base grid plate near the side; the locking structure includes a locking wheel and an adjusting rod, the rotating grid plate has an installation cavity at one end near the base grid plate, the locking wheel is installed in the installation cavity, the locking wheel is coaxially fixed to the circumference of the rotating shaft and rotates synchronously with the rotating shaft; the adjusting rod passes through the base grid plate and extends into the installation cavity, the adjusting rod can move along the axial direction; when the adjusting rod engages with the locking wheel, the locking wheel is locked in position, when the adjusting rod disengages from the locking wheel, the locking wheel rotates freely.

[0014] By adopting the above technical solution, when the adjusting rod engages with the locking wheel, the rotation of the locking wheel can be effectively restricted, thereby fixing the adjustable plate at a specific angle. This ensures that the chair's posture is stable during use and will not change angle arbitrarily due to external forces, providing safe and reliable support for the user. When it is necessary to adjust the angle of the adjustable plate, the adjusting rod is disengaged from the locking wheel, allowing the locking wheel to rotate freely. This allows the user to quickly adjust the shape of the chair according to their needs, meeting diverse usage requirements.

[0015] Optionally, the circumference of the locking wheel is provided with a plurality of locking protrusions evenly spaced along the circumference, and a locking groove is formed between two adjacent locking protrusions, the locking groove being used to lock with the adjusting rod.

[0016] By adopting the above technical solution, the cooperation between the locking wheel and the adjusting rod makes the locking structure more secure and stable when locked, maintaining a reliable locking state, effectively preventing the adjustable plate from rotating accidentally, and ensuring user safety. In addition, the locking groove provides multiple locking points, allowing the adjustable plate to be adjusted to multiple angles. Users can precisely adjust the adjustable plate to a suitable angle according to their own comfort and actual needs, further improving the comfort and practicality of the lounge chair.

[0017] Optionally, a handle is installed at one end of the adjusting rod, and a locking block is provided at the end of the adjusting rod away from the handle. The locking block can be inserted into the snap-fit ​​groove. A limit groove is opened at the end of the base grid plate near the rotating grid plate. An elastic element is installed in the limit groove. The elastic element acts on the locking block to push the locking block into the snap-fit ​​groove. When the locking block snaps into the snap-fit ​​wheel, the snap-fit ​​wheel is locked in position. When the locking block disengages from the snap-fit ​​groove and enters the limit groove, the snap-fit ​​wheel rotates freely.

[0018] By adopting the above technical solution, the handle provides users with a convenient point of force application. Pulling the handle controls the locking block to disengage from the snap-fit ​​groove and enter the limiting groove. After the force on the handle is released, the locking block is pushed back into the snap-fit ​​groove by the elastic element. The operation is simple. At the same time, the limiting groove can ensure that the locking block is stably placed, preventing the locking block from shaking or misaligning in the installation cavity, thus ensuring the smoothness and reliability of the adjustment rod operation.

[0019] Optionally, the elastic element is configured as a compression spring, the elastic element is sleeved around the adjusting rod, one end of the elastic element is connected to the end of the locking block near the adjusting rod, and the other end of the elastic element is connected to the bottom of the limiting groove.

[0020] By adopting the above technical solution, the compression spring is sleeved around the adjustment rod, which can provide a guide limit for the compression spring, so that the force of the compression spring is along the direction of the axis of the adjustment rod, thereby pushing the locking block to quickly and accurately insert into the locking groove, so as to achieve stable and reliable locking.

[0021] Optionally, the bottom of the base grid plate is provided with an anti-slip rubber pad.

[0022] By adopting the above technical solution, the anti-slip rubber pad effectively increases the friction between the lounge chair and the ground, preventing the lounge chair from sliding or shifting due to user movement or uneven force during use, thus improving safety and stability during use.

[0023] By adopting the above technical solution, the number of connection links between components is reduced, the strength and durability of the locking structure are improved, the risk of failure caused by loose or detached components is reduced, and the service life of the lounge chair is extended.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Users can adjust the lounge chair to a suitable posture by rotating the adjustable plate and locking it with the locking mechanism. The operation is simple and meets the diverse usage needs of users in different scenarios.

[0026] 2. When the adjusting rod engages with the locking wheel, it effectively restricts the rotation of the locking wheel, thereby fixing the adjustable plate at a specific angle. This ensures the stability of the chair during use and prevents it from changing angle arbitrarily due to external forces, providing safe and reliable support for the user. When it is necessary to adjust the angle of the adjustable plate, simply disengage the adjusting rod from the locking wheel, allowing the locking wheel to rotate freely. This makes operation convenient.

[0027] 3. By evenly spaced multiple locking protrusions on the periphery of the locking wheel to form multiple locking grooves, multiple locking points are provided for the adjustment rod, enabling the adjustable plate to be adjusted to multiple angles. Users can precisely adjust the adjustable plate to a suitable angle according to their own comfort and actual needs, further improving the comfort and practicality of the lounge chair.

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0036] This application discloses a lounge chair that can be transformed into various postures, referring to... Figure 1 and Figure 2 The chair includes a fixed base 1, adjustable plates 2, and a locking structure 3. The fixed base 1 has an inverted U-shaped structure. There are two adjustable plates 2, which are respectively rotatably installed at opposite ends of the fixed base 1 and can be locked by the locking structure 3. This allows the two adjustable plates 2 to either fit into the two ends of the fixed base 1 to form a basic lounge chair without a backrest and leg rest, or to rotate independently to form a lounge chair with a backrest, leg rest, or both, thus meeting the diverse usage needs of users in different indoor and outdoor scenarios.

[0037] The fixed base 1 includes multiple evenly spaced base grid plates 11, with grid gaps 12 formed between adjacent base grid plates 11. Each base grid plate 11 is inverted U-shaped, with rotating shafts 4 passing through its two corners, forming a unified inverted U-shaped structure that provides stable support for the lounge chair. The bottom of each base grid plate 11 is equipped with an anti-slip rubber pad to enhance friction. Two adjustable plates 2 are connected to two rotating shafts 4, and both adjustable plates 2 can rotate around the axis of their respective rotating shafts 4.

[0038] The adjustable plate 2 includes multiple rotating grid plates 21, which are sequentially installed in the grid gap 12 located at the same end of the fixed base 1. The rotating shaft 4 passes through the end of the rotating grid plate 21 and is fixedly connected, so that when the rotating grid plate 21 rotates, it can drive the rotating shaft 4 to rotate synchronously, and rotating any rotating grid plate 21 can drive all rotating grid plates 21 to rotate synchronously.

[0039] The locking structure 3 is installed at the connection between the rotating grid plate 21 and the base grid plate 11 near the side. (Refer to...) Figure 3 and Figure 4The locking structure 3 includes a locking wheel 31 and an adjusting rod 32. A mounting cavity 22 is provided at one end of the rotating grid plate 21 near the base grid plate 11. The locking wheel 31 is installed in the mounting cavity 22 and is coaxially fixed to the circumference of the rotating shaft 4 by a positioning pin. When the rotating shaft 4 rotates, it drives the locking wheel 31 to rotate synchronously. Multiple locking protrusions 311 are integrally connected to the circumference of the locking wheel 31. These protrusions 311 are evenly spaced along the circumference of the locking wheel 31, and a locking groove 312 is formed between adjacent protrusions 311. The locking groove 312 engages with the adjusting rod 32 to lock the position of the adjustable plate 2.

[0040] One end of the adjusting rod 32 is threadedly connected to a handle 33. The end of the adjusting rod 32 away from the handle 33 passes through the base grid plate 11 and extends into the mounting cavity 22. The adjusting rod 32 can move along the axial direction. The end of the adjusting rod 32 away from the handle 33 is integrally formed with a locking block 34. The locking block 34 has a cylindrical structure and its diameter is larger than that of the adjusting rod 32. The locking block 34 can be inserted into the snap-fit ​​groove 312 and abut against the inner wall of the mounting cavity 22 to lock the position of the snap-fit ​​wheel 31.

[0041] A limiting groove 13 is formed at one end of the base grid plate 11 near the rotating grid plate 21, and an elastic element 14 is provided in the limiting groove 13. The elastic element 14 provides an elastic force to the locking block 34 toward the rotating grid plate 21, so that the locking block 34 abuts against the inner wall of the mounting cavity 22 away from the base grid plate 11. In this embodiment, the elastic element 14 is a compression spring, which is sleeved around the adjusting rod 32, with one end of the compression spring connected to the end of the locking block 34 near the adjusting rod 32, and the other end of the compression spring connected to the bottom of the limiting groove 13.

[0042] When stationary, the end of the locking block 34 away from the adjusting rod 32 abuts against the inner wall of the mounting cavity 22. At this time, the locking block 34 is inserted into the snap-fit ​​groove 312, and the side wall of the locking block 34 is limited by the side wall of the snap-fit ​​protrusion 311, so that the position of the snap-fit ​​wheel 31 is locked and the rotation angle of the adjustable plate 2 is locked. When the handle 33 is pulled toward the end away from the rotating grid plate 21, the elastic element 14 deforms, and the locking block 34 disengages from the snap-fit ​​groove 312 and enters the limiting groove 13. At this time, the snap-fit ​​wheel 31 can rotate freely, thereby realizing the adjustment of the angle of the adjustable plate 2. When the force on the handle 33 is released, the locking block 34 moves away from the bottom of the limiting groove 13 under the action of the elastic force of the elastic element 14 until the locking block 34 is inserted into the snap-fit ​​groove 312 and abuts against the inner wall of the mounting cavity 22, thereby locking the rotation angle of the adjustable plate 2.

[0043] Reference Figure 5When the adjustable plate 2 at one end is rotated to the vertical position, it can form a lounge chair with a backrest, which is suitable for sitting for a long time, such as reading or watching TV indoors. The backrest can provide good lumbar support for the user and reduce fatigue.

[0044] Reference Figure 2 and Figure 6 When one adjustable plate 2 remains vertical and the other adjustable plate 2 is rotated to a horizontal position, a lounge chair with a backrest and leg rest can be formed. This form further enhances comfort, and the leg rest can effectively relieve leg pressure. It is suitable for use when relaxing, such as sunbathing or resting on the balcony.

[0045] When both adjustable plates 2 are in a horizontal position, a bench-like position similar to a recliner can be formed. This position is suitable for lying down and resting, such as during an outdoor lunch break or a short indoor nap, providing a more comfortable resting experience.

[0046] The same lounge chair can be transformed at any time according to different needs of daily activities, replacing multiple traditional chairs in different scenarios. This eliminates the need to purchase multiple different types of chairs, helping to save space and costs for users.

[0047] In this embodiment, the fixed base 1 is made of a sturdy metal material, such as aluminum alloy or stainless steel, and the adjustable plate 2 is made of a metal material that matches the fixed base, ensuring the strength and durability of the lounge chair. To improve user comfort, a soft material, such as sponge or fabric, can be covered on the surfaces of the fixed base 1 and the adjustable plate 2 to provide more comfortable support for the user.

[0048] The implementation principle of a multi-positional leisure chair disclosed in this application is as follows: the fixed base 1 has an inverted U-shaped structure, and two adjustable plates 2 are respectively rotated and installed at opposite ends of the fixed base 1 and locked by the locking structure 3. This allows the two adjustable plates 2 to either fit into the two ends of the fixed base 1 to form a basic leisure chair without a backrest and leg rest, or to rotate independently to form a leisure chair with a backrest, a leg rest, or both, thus meeting the diverse usage needs of users in different indoor and outdoor scenarios.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
