Description

Technical Field

[0001] This application relates to the field of leisure products, and more particularly to a floating chair. Background Technology

[0002] A floating chair is a type of seating specifically designed for aquatic environments, primarily used in swimming pools, lakes, beaches, and other similar settings, providing users with stable posture support on the water's surface. Its core technologies involve buoyancy materials, structural stability, ergonomic design, and portability optimization, falling within the cross-disciplinary field of leisure products, water sports equipment, and medical rehabilitation devices.

[0003] Currently, the main types of floating chairs on the market are inflatable floating chairs, foam-filled floating chairs, and rigid-structure floating chairs. Inflatable floating chairs are typically made of PVC or TPU materials, and buoyancy is adjusted by inflating and deflating an air valve. Foam-filled floating chairs use EPE (expanded polyethylene) or EVA (ethylene vinyl acetate) foam as the buoyancy core. Rigid-structure floating chairs use waterproof wood or hollow plastic designs, such as folding floating chairs. With all these types of floating chairs, once the product is formed, the user cannot adjust the structure of the floating chair, making it unsuitable for different usage conditions.

[0004] Therefore, it is necessary to provide a floating chair that can flexibly change its usage status. Utility Model Content

[0005] Therefore, it is necessary to provide a floating chair that can flexibly change its usage status.

[0006] An embodiment of this application provides a floating chair, comprising:

[0007] Two floating boards are arranged facing each other and overlapping along their thickness direction;

[0008] The hinge buckle, along the length of the float plate, comprises two hinge buckles respectively hinged to opposite ends of the float plate, and

[0009] The floating board is made of flexible material. The two floating boards are bent and staggered relative to each other by two hinged buckles to form an unfolded state for users to ride on in the water.

[0010] Preferably, one or more through holes are provided at either end of the floating plate along its length, and the two hinge buckles are respectively hinged in either of the through holes at opposite ends of the floating plate.

[0011] Preferably, the hinged buckle includes a female buckle, a male buckle inserted into the female buckle and engaging with it, and a locking member inserted into the male buckle and engaging with it. When the locking member is inserted into the male buckle, the locking member is located on the side of the male buckle away from the female buckle, so as to prevent the male buckle from disengaging from the female buckle, thereby locking the engagement between the male buckle and the female buckle.

[0012] Preferably, the male buckle includes a male buckle end cap and a male buckle connecting portion extending perpendicular to the end cap; the female buckle includes a female buckle end cap and a female buckle connecting portion extending perpendicular to the female buckle end cap; the male buckle connecting portion is hollow inside, and the locking member is inserted into the male buckle connecting portion and engages with it; the female buckle connecting portion is hollow inside, and the male buckle connecting portion is inserted into the female buckle connecting portion and engages with it.

[0013] Preferably, the direction perpendicular to the male and female end caps is designated as the first direction, and the direction perpendicular to the first direction is designated as the second direction. The male buckle connection portion is provided with a cantilever extending along the second direction. The two sides of the cantilever extend outward to form hooks that respectively engage with the female buckle. The female buckle connection portion is provided with a stop opening extending along the second direction. Multiple stop openings are provided on both symmetrical sides of the outer wall. When the male buckle is inserted into the female buckle along the first direction, the hooks on the cantilever abut against the inner wall of the female buckle connection portion, thereby deforming the cantilever inward along the second direction. When the hooks are pushed forward along the first direction to the position corresponding to the stop opening, the hooks slide into the stop opening, thereby causing the cantilever to spring back outward along the second direction to restore its original shape, thus completing the engagement of the male buckle and the female buckle.

[0014] Preferably, there are multiple gear positions, which are evenly arranged along the first direction; the top of the hook has a bevel that forms an angle with the second direction. When the hook slides into the gear position, it continues to push the male buckle along the first direction. The bevel of the hook abuts against the gear position, causing the cantilever to deform inward along the second direction. The hook can then continue to advance along the first direction to the next gear position, thereby achieving the engagement of the male buckle and the female buckle in another gear position.

[0015] Preferably, the cantilever has a through-hole in the second direction, and the outer wall of the locking member has a protrusion that mates with the through-hole. When the locking member is inserted into the male buckle in the first direction, the protrusion slides into the through-hole, thereby achieving a snap-fit ​​engagement between the locking member and the male buckle.

[0016] Preferably, when viewed along the first direction, the included angle between the two floating plates is denoted as R; the state in which the two floating plates are completely overlapping is denoted as the retracted state; the state in which the two floating plates are bent and staggered relative to each other with the two hinged fasteners as connection points is denoted as the unfolded state; and the included angle R between the two floating plates in the unfolded state satisfies the following relationship:

[0017] 0° < R < 180°.

[0018] Preferably, the floating plate material is one or a combination of XPE, EVA, PE, EPS, and EPE.

[0019] Preferably, the floating plate has symmetrical notches in the middle, and the notches are one or a combination of two of the following: arc-shaped notches or polygonal notches.

[0020] The technical effect is as follows:

[0021] By setting two floating plates that overlap each other along their thickness direction and hinge them to the opposite ends of the floating plates with two hinge buckles, and the floating plates are made of flexible material, the two floating plates are bent and staggered relative to each other with the two hinge buckles as connection points to form an unfolded state for users to ride in the water. By staggering them at different angles, different usage states can be combined. Attached Figure Description

[0046] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0047] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0048] See Figures 1-22 The embodiments of this application provide a floating chair 100, including: a floating plate 10 and a hinge buckle 20.

[0049] Two floating panels 10 are arranged opposite each other along their thickness direction. Two hinge buckles 20 are respectively hinged to opposite ends of the floating panels 10 along their length. This double-panel, end-hinged design secures the two overlapping flexible floating panels 10 along their thickness direction using the end hinge buckles 20. This not only allows for flattening and space-saving storage, but also enables free unfolding in the water at different angles (0° < R < 180°) using the two hinge points as pivots, meeting various posture requirements such as lying flat or sitting.

[0050] Specifically, the floating board 10 is made of a flexible material, which can be one or more of XPE, EVA, PE, EPS, and EPE. In this embodiment, the floating board 10 is made of EVA material. The floating board 10 made of EVA foam material has a low-density closed-cell structure that ensures sufficient buoyancy while not easily absorbing water and increasing weight. It has excellent flexibility and elasticity, which can effectively buffer water surface fluctuations and conform to the human body curve to improve the sitting comfort. At the same time, EVA itself has excellent weather resistance and corrosion resistance to ultraviolet rays, seawater, and common corrosive chemical media. Even if exposed to outdoor water for a long time, it is not easy to age and crack. The mature die-cutting and hot-pressing molding process can not only accurately manufacture the central arc or polygonal fitting notch 12, reducing the weight of the whole machine and enhancing the fitting safety, but also mass production with controllable costs. More importantly, EVA is non-toxic, odorless, environmentally friendly and safe, which makes this floating chair significantly improved in terms of comfort, buoyancy stability, durability and user health protection.

[0051] Specifically, the two floating panels 10 are bent and staggered relative to each other at the two hinged fasteners 20 as connection points, forming an unfolded state for the user to ride on in the water. Different usage states are formed based on different staggered angles, and are not limited to such... Figures 2-6 The diagram illustrates this. This staggered structure, with double hinge points as the pivot, allows the two flexible floating panels 10 to seamlessly transition from a flat, stowed state to an unfolded state of any angle (0° < R < 180°) in the water. Users can freely adjust them to various postures such as lying down, sitting, or leaning back. Multi-position locking ensures stable load-bearing and distributes force at different angles, improving seating support and anti-tipping performance. At the same time, the staggered panels can flexibly conform to the curves of the human body, achieving more ergonomic back and hip support, enhancing comfort and safety.

[0052] Preferably, one or more through holes 11 are provided at either end of the floating plate 10 along its length, and the two hinge buckles 20 are respectively hinged into either of the through holes 11 at opposite ends of the floating plate 10. In this embodiment, there is one through hole 11 at each of the left and right ends, and the two hinge buckles 20 are respectively disposed in the two through holes 11. In other embodiments, it may also be as follows: Figure 9 and Figure 10 Other different combinations are shown. By creating through holes 11 at both ends of the floating plate 10 and directly hinged the hinge buckle 20 within the through holes 11, a tight, integrated connection between the hinge point and the plate body can be achieved, making the force path more direct and evenly distributed, thereby improving the tear resistance and durability of the hinge joint. The symmetrical layout of the through holes 11 not only simplifies the assembly process but also allows for flexible adjustment of the hinge point position according to different needs (such as...). Figure 9 , Figure 10The multi-hole combination shown can change the range of the opening angle and the comfortable support area, so as to achieve adaptive fit for different body shapes and usage scenarios. In addition, the combination of through holes 11 and flexible plates reduces the use of additional metal or rigid brackets, reduces the overall weight and cost, while maintaining structural stability and overall aesthetics.

[0053] Preferably, the hinge buckle 20 includes: a female buckle 21, a male buckle 22, and a locking member 23.

[0054] The male buckle 22 is inserted into the female buckle 21, thus engaging with it. The locking member 23 is inserted into the male buckle 22, also engaging with it. When the locking member 23 is inserted into the male buckle 22, it is positioned on the side of the male buckle 22 away from the female buckle 21, preventing the male buckle 22 from disengaging from the female buckle 21, thereby locking the engagement between the male buckle 22 and the female buckle 21. This three-stage locking structure—the male buckle 22 inserts into the female buckle 21 and initially engages, then the locking member 23 is inserted into the male buckle 22 and positioned on the side of the male buckle 22 away from the female buckle 21—achieves a safe locking system from initial load-bearing to final locking. In dynamic water conditions and when used by multiple people, it effectively prevents the hinge point from loosening due to vibration or external force, improving the reliability and safety of the structure. Simultaneously, the locking member 23 can be quickly assembled or disassembled via unidirectional insertion, without the need for complex tools, thus combining ease of maintenance and user-friendly operation.

[0055] Preferably, the male buckle 22 includes a male buckle end cap 221 and a male buckle connecting portion 222. The female buckle 21 includes a female buckle end cap 211 and a female buckle connecting portion 212.

[0056] The male snap-fit ​​connector 222 extends along the direction perpendicular to the end cap. The female snap-fit ​​connector 212 extends along the direction perpendicular to the female snap-fit ​​end cap 211. The male snap-fit ​​connector 222 is hollow inside, and the locking member 23 is inserted into the male snap-fit ​​connector 222 and engages with it. The female snap-fit ​​connector 212 is also hollow inside, and the male snap-fit ​​connector 222 is inserted into the female snap-fit ​​connector 212 and engages with it. The connection parts of the male buckle 22 and the female buckle 21 both adopt a hollow cylindrical extension structure perpendicular to the end cap, which allows the male buckle connection part 222 to be smoothly inserted into the female buckle connection part 212 and achieve initial engagement. The hollow internal design not only provides an insertion space for the locking member 23, but also ensures that after the locking member 23 and the male buckle connection part 222 are firmly engaged, the male buckle 22 can be effectively prevented from falling out in reverse within a limited stroke. The overall cylindrical structure allows the bending and shearing forces generated by the hinge buckle 20 under stress to be transmitted axially, thereby maximizing the engagement strength and durability, while simplifying the mold structure and assembly process.

[0057] Preferably, the direction perpendicular to the male end cap 221 and the female end cap 211 is denoted as the first direction F1, and the direction perpendicular to the first direction F1 is denoted as the second direction F2.

[0058] The male buckle connection 222 is provided with a cantilever 2221 extending along the second direction F2. The two sides of the cantilever 2221 extend outward to form hooks 2222 that respectively engage with the female buckle 21. The female buckle connection 212 is provided with a stop opening 2121 extending along the second direction F2. Multiple stop openings 2121 are provided on both sides of the outer wall. When the male buckle 22 is inserted into the female buckle 21 along the first direction F1, the hooks 2222 on the cantilever 2221 abut against the inner wall of the female buckle connection 212, thereby deforming the cantilever 2221 inward along the second direction F2. When the hooks 2222 are pushed forward along the first direction F1 to the position corresponding to the stop opening 2121, the hooks 2222 slide into the stop opening 2121, thereby the cantilever 2221 springs back outward along the second direction F2 to restore its original shape, thus completing the engagement of the male buckle 22 and the female buckle 21.

[0059] The combined structure of the cantilever 2221, hook 2222, and multi-position slot 2121 allows the male buckle 22 to achieve initial transition locking through the elastic deformation of the cantilever 2221 when inserted into the female buckle 21. After the hook 2222 slides into different position slots 2121, it automatically rebounds to complete precise positioning, thus supporting a freely switchable and stable multi-angle locking system. Users only need to insert or push along the first direction F1 to easily adjust and lock any angle without additional tools. The even distribution of multiple positions avoids stress concentration at a single point, improving durability and load-bearing capacity. At the same time, the elastic cantilever 2221 solution takes into account both the high fatigue resistance of repeated assembly and disassembly and the smooth operation experience of ergonomics.

[0060] Preferably, there are multiple gear positions 2121, which are evenly arranged along the first direction F1. The top of the hook 2222 has a bevel 22221 that forms an angle with the second direction F2. When the hook 2222 slides into the gear position 2121, it continues to push the male buckle 22 along the first direction F1. The bevel 22221 of the hook 2222 abuts against the gear position 2121, causing the cantilever 2221 to deform inward along the second direction F2. The hook 2222 can then continue to advance along the first direction F1 to the next gear position 2121, thereby achieving the engagement of the male buckle 22 and the female buckle 21 in another gear position 2121.

[0061] The multi-position openings 2121 are evenly arranged along the axial direction. Combined with the design of the beveled surface 22221 at the top of the hook 2222, it achieves progressive opening and locking without the need for additional tools: after the male buckle 22 is inserted into any position, the hook 2222 springs back to position and can stably bear the load; when the user continues to push in the direction of the insertion force, the beveled surface 22221 and the edge of the position opening 2121 collide obliquely, causing the cantilever 2221 to retract inward, the hook 2222 to disengage from the current position and slide into the next position, thus seamlessly switching to a larger angle; this structure not only ensures a smooth transition and precise stopping between multiple positions, but also reduces single-point wear by distributing the force, improves the fatigue resistance and service life of the hinge buckle 20, and provides users with a smooth and intuitive angle adjustment experience.

[0062] Preferably, the cantilever 2221 has a card interface 2223 extending along the second direction F2, and the outer wall of the locking member 23 has a protrusion 231 that cooperates with the card interface 2223. When the locking member 23 is inserted into the male buckle 22 along the first direction F1, the protrusion 231 slides into the card interface 2223, thereby realizing the card engagement between the locking member 23 and the male buckle 22.

[0063] The design of the card interface 2223, which runs through the second direction F2, and the protrusion 231 on the outer wall of the locking member 23, allows the cantilever 2221 to automatically engage and lock after the male buckle 22 has initially engaged. This is achieved by inserting the locking member 23 along the first direction F1, without any additional actions or tools. The mechanical limitation of the cantilever 2221 can be completed in the final step, thus completely blocking the path of the hook 2222 to pop out and return to its original position. This secondary locking mechanism not only significantly improves the resistance of the hinge point to loosening under water surface vibration and impact loads, but also reduces the excessive reliance on material elasticity, further improving safety and durability, while maintaining ease of assembly and disassembly and intuitive operation.

[0064] Preferably, when viewed along the first direction F1, the included angle between the two floating plates 10 is denoted as R. The state in which the two floating plates 10 are completely overlapping is denoted as the retracted state. The state in which the two floating plates 10 are bent and staggered relative to each other with the two hinge buckles 20 as connection points is denoted as the unfolded state. In the unfolded state, the included angle R between the two floating plates 10 satisfies the relationship: 0° < R < 180°. Different usage states are formed based on different staggered included angles R, and are not limited to such... Figures 2-6 The illustration.

[0065] By using two floating panels 10 as hubs with two hinged buckles 20, the floating chair 100 can freely switch between a folded state (R = 0°) and an unfolded state (0° < R < 180°). When not in use, it can be compactly closed for easy carrying and storage. Furthermore, it can be quickly adjusted to various postures such as lying flat, half-sitting, and backrest to suit different water surface environments and user needs. The evenly distributed locking points between the multiple positions ensure stable support and anti-tipping performance at any R value, while dispersing stress to avoid fatigue failure caused by excessive force on a single point. The overall structure takes into account flexibility, stability, and comfort, greatly improving the applicability and user experience of the floating chair 100.

[0066] Preferably, the floating plate 10 has symmetrically provided notches 12 in the middle, and the notches 12 are one or a combination of two of the following: arc-shaped notches 12 or polygonal notches 12. Symmetrically providing arc-shaped or polygonal notches 12 in the middle of the floating plate 10 not only conforms to the curves of the user's back or legs, improving seating comfort and ergonomic support, but also effectively reduces the overall weight of the plate, lowers water resistance and eddy current generation, and enhances water surface maneuverability. The notches 12 also serve as drainage channels, preventing water accumulation on the plate, improving drainage performance and safety, while simplifying the die-cutting process, reducing material consumption, and achieving the best balance between lightweight and efficient production.

[0067] In this way, by setting two floating plates 10 that are directly opposite each other along their thickness direction and hinged to the opposite ends of the floating plates 10 by two hinge buckles 20 respectively, and the floating plates 10 are made of flexible material, by bending and offsetting the two floating plates 10 relative to each other with the two hinge buckles 20 as connection points, an unfolded state for users to ride in the water can be formed. By offsetting them at different angles, different usage states can be combined.

[0068] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
