Description

Technical Field

[0001] This invention relates to a seesaw, and more specifically, to a jellyfish-inspired seesaw, belonging to the field of recreational and sports facilities. Background Technology

[0002] Traditional seesaws are standard recreational facilities in residential communities and kindergartens due to their simple structure and easy installation. However, traditional seesaws also have many problems, such as difficulty in playing if there is a large weight difference between the riders on both sides, limited gameplay, inability to accommodate multiple people, and lack of parent-child interaction. Existing patented technologies mainly focus on improving the gameplay, such as changing the movements, adding fun features like sound and light effects, and improving the safety of traditional seesaws. However, existing technologies do not provide a good solution for how to make seesaw activities simple, convenient, and fun for multiple people. Furthermore, multiple participants present more complex usage scenarios, such as those needing parent-child interaction, those seeking excitement, and those who don't want to exert themselves. Is it possible to create a seesaw that meets these more complex needs? As a form of public recreational equipment, especially for children, seesaws not only fulfill functional requirements but also have numerous emotional appeals. Existing patented technologies primarily focus on developing functional aspects, with less attention paid to emotional appeal. However, emotional appeal is crucial to the market value of patented technologies. As a planktonic organism, jellyfish move in water by deforming their transparent, bell-shaped bodies, causing their tentacles to sway. They possess exceptional stability and agile movement, appearing graceful and dreamlike under light, making them very popular. If seesaws could emulate the dynamic characteristics of jellyfish in the user's interactive experience, users would have a deeper sense of participation in both the user experience and their psychological engagement.

[0003] If a seesaw can meet the above complex usage requirements, it will greatly improve the seesaw's ability to adapt to different scenarios, and its market value and social value will have significant positive implications. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a jellyfish-inspired seesaw that uses a combination of single or double seats, mimics the dynamic characteristics of a jellyfish, employs modular components, and offers various play options such as tilting, swinging, and sliding. It also features the ability to switch between electric and manual modes.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: This invention discloses a jellyfish-inspired seesaw, comprising a primary support and a universal joint. The primary support includes a base plate and a cylinder connected to the base plate. A sliding sleeve is fitted onto the cylinder, allowing for vertical displacement and rotational movement along the cylinder. Several Z-axis holes are connected around the outer circumference of the sliding sleeve, and each Z-axis hole is connected to a sliding rod via a universal joint. The ends of the sliding rods are arranged in a circular pattern, and each sliding rod is linked to a rotating seat assembly. The rotating seat assembly includes a secondary support fixed to the base plate, on which a rotating seat is rotatably and fixedly connected. A rotating sleeve is hinged to the rotating seat, and a sliding hole is formed on the rotating sleeve. The sliding rod is movably inserted through the sliding hole, and a seat assembly is connected to the free end of the sliding rod. By actuating the seat assembly, the sliding rod's sliding and rotational movement on the cylinder of the primary support are separately limited, thereby enabling three different usage modes of the seesaw: rotation, lifting, and rotation.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In the description of the invention, it should be noted that the terms "upper", "lower", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0041] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an indirect connection through an intermediate medium, but the connections at various points do not affect the multi-position folding of this application. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] The ingenuity of this invention lies in the use of a continuous swing mechanism, universal joint, and slider linkage to realize a variety of new ways of using the seesaw, such as "tilting," "swinging," and "sliding," which are different from traditional seesaws. It can meet the needs of users from single to multiple people, and the combination of large and small seats can meet the needs of parent-child companionship. The biomimetic shape and movements are more likely to match the emotional experience needs of users.

[0043] Principle: The motor 14 transmits its motion to the sliding sleeve 3 via the crank 13, the sliding transmission block 12, and the sliding transmission shaft 11. One end of the crank 13 is fixed to the shaft of the motor 14, and the other end can slide on the connecting rod of the sliding transmission block 12. The top surface of the sliding transmission block 12 is in contact with the bottom surface of the sliding transmission shaft 11 (rotatable connection), and the two can generate relative rotational motion around the Z-axis. The sliding transmission shaft 11 is installed in the sliding shaft hole 3.2 and can rotate around the axial direction of the sliding shaft hole 3.2. The sliding sleeve 3 can move up and down and rotate along the cylinder of the first bracket 1. The Z-axis hole 3.1 of the sliding sleeve 3 is connected to the Z-axis shaft 4.1 on the universal joint 4. The X-axis shaft 4.2 of the universal joint 4 is connected to the X-axis hole 5.1 of the sliding rod 5. The sliding rod 5 is installed in the sliding hole 6.1 of the rotating sleeve 6. The rotating sleeve 6 is connected to the rotating seat 7 through the rotating hole 6.2 and can rotate around the axial direction of the rotating hole 6.2. The rotating seat 7 is connected to the rotating seat frame 8 via bearing 7.1 and can rotate axially around bearing 7.1. When driven by motor 14, the seesaw's continuous movement can be achieved without manual intervention. When motor 14 and related components are removed, the traditional manual-driven movement can be achieved. In this case, the sliding and rotation of the sliding sleeve 3 on the cylinder of the first support 1 can be separately limited, thus enabling three different usage modes: rotation, lifting, and turning. The small seat assembly 9 and the large seat assembly 10 can be installed simultaneously, or only one of them can be installed, or they can be installed in combination, etc. The small seat assembly 9 can achieve three actions: "tilting," "swinging," and "sliding"; the large seat assembly 10 can achieve two actions: "tilting" and "swinging." The Z-axis hole 3.1 on the sliding sleeve 3 can have a single or multiple features, that is, the seesaw can realize normal use features from single to multiple, with high flexibility and enough for multiple people to use at the same time. The motor frame 15 is used to install and adjust the height position of the motor 14, and the required height can be set according to the site requirements. As a preferred option, three sliding shaft holes 3.2 are also connected around the outer circumference of the sliding sleeve 3, that is, corresponding to three motors 14 and three motor frames 15. The detachable top cover 1.1 on the cylinder can be equipped with LED light groups, and the semi-transparent outer cover 2 presents a jellyfish-like visual feature through the lighting effect.

[0044] Specifically: The usage of this invention is as shown in Figures 1-23. By combining different modules of the seesaw, various usage modes can be achieved, such as electric double seat mode, electric small seat mode, electric large seat mode, electric hybrid mode, double seat mode, small seat mode, large seat mode, and hybrid mode.

[0045] Example 1 (Spindle 7 is fixed on bracket 8, using both child and adult seats): This invention discloses a jellyfish-inspired seesaw, comprising a primary support 1 and a universal joint 4. The primary support 1 includes a base plate and a cylinder connected to the base plate. A sliding sleeve 3 is fitted onto the cylinder, allowing for vertical displacement and rotational movement along the cylinder. Several Z-axis holes 3.1 are connected around the outer circumference of the sliding sleeve 3. Each Z-axis hole 3.1 is connected to a sliding rod 5 via the universal joint 4. The ends of the sliding rods 5 are arranged in a circular pattern, and each sliding rod 5 is linked to a rotating seat assembly. The device includes a second bracket 8 fixed to the base plate, a rotating seat 7 fixedly connected to the second bracket 8, a rotating sleeve 6 hinged to the rotating seat 7, a sliding hole 6.1 opened on the rotating sleeve 6, a sliding rod 5 movably passing through the sliding hole 6.1, and a small seat group 9 connected to the free end of the sliding rod 5. By actuating the small seat group 9, the sliding rod 5 can separately limit the sliding and rotation of the sliding sleeve 3 on the cylinder of the first bracket 1, thereby realizing three different usage modes of the seesaw: rotation, lifting, and rotation. The small seat assembly 9 includes a seat plate 9.3, two armrests 9.1, and two pedals 9.2. The free end of the slide rod 5 is provided with a seat plate hole 5.3 and armrest holes 5.2 located on both sides of the seat plate hole 5.3 and symmetrically arranged. The two armrests 9.1 are rotatably connected to an armrest hole 5.2 via a first pivot. The two pedals 9.2 are connected to a first pivot to achieve linkage with the armrests 9.1. The pedals 9.2 can rotate left and right in the horizontal direction, and the seat plate 9.3 is rotatably connected to the seat plate hole 5.3 in the vertical direction. The seat plate 9.3, armrests 9.1, and pedals 9.2 constitute a child seat. It also includes two foot pedal links 9.4 and a guide rail with a groove 5.4. The guide rail is connected to the lower end of the slide rod 5 and extends beyond the free end of the slide rod 5 along the direction of the slide rod 5. The two foot pedal links 9.4 are rotatably connected to a first rotating shaft. The other ends of the two foot pedal links 9.4 are hinged to form a sliding part, which is reciprocally sliding within the groove 5.4. A support rod is connected to each of the left and right sides of the rotating sleeve 6. The support rod is located below the small seat assembly 9 and its end extends past the small seat assembly 9. The end of the support rod is connected to... A large seat assembly 10 is attached to the seat, which includes a seat plate and an armrest frame connected to a support rod. The armrest frame is located at the front end of the seat plate and forms the backrest of the child seat. The armrest frame and the large seat assembly 10 together form an adult seat. The armrest frame includes a symmetrical and connected frame, which includes a bottom crossbar connected to the support rod. Both ends of the crossbar curve upwards and extend to a first longitudinal bar and a second longitudinal bar. The first longitudinal bar is located in front of the second longitudinal bar, and its height is lower than that of the second longitudinal bar. A first connecting rod is connected between the longitudinal rod and the second longitudinal rod, and the upper end of the first connecting rod extends upward to form a second connecting rod. A backrest rod is connected between the second connecting rods on the two frames. Several sliding shaft holes 3.2 are also connected around the outer circumference of the sliding sleeve 3. A sliding transmission shaft 11 is installed in each sliding shaft hole 3.2. The sliding transmission shaft 11 can rotate axially around the sliding shaft hole 3.2. A sliding transmission block 12 is rotatably connected to the bottom surface of the sliding transmission shaft 11 to achieve relative rotational motion between the two around the Z-axis. The sliding transmission block 12 includes... A connecting rod is rotatably fitted with a crank 13, which can slide left and right on a sliding transmission block 12. The crank 13 is connected to the rotating shaft of a motor 14. The motor 14 transmits its motion to the sliding sleeve 3 through the crank 13, the sliding transmission block 12, and the sliding transmission shaft 11. The motor 14 is mounted on a base plate. Several motor frames 15 are connected to the base plate. The number of motor frames 15 is the same as the number of motors 14. The motors 14 are mounted on the motor frames 15, which are used to install and adjust the height position of the motors 14.

[0046] When driven by motor 14, the seesaw's continuous movement can be achieved without manual intervention. By separately limiting the sliding and rotation of the sliding sleeve 3 on the cylinder of support 1, three different usage modes—rotation, lifting, and ascending—can be realized. Figure 18-20 As shown, in this application, preferably, three sliding shaft holes 3.2 are also connected around the outer peripheral surface of the sliding sleeve 3, which correspond to three synchronous motors 14; Usage Method 1: As shown in Figure 1, Figure 3 , Figure 4 The image shows several usage modes of the "electric two-seat mode". Figure 2 This is a breakdown diagram of the overall structure, used to illustrate the specific structure.

[0047] Mode 1: Figure 1 The overall state of the seesaw with outer cover 2 as perceived by the user is as follows: during movement, the distance between the small seat 9 and the outer cover 2 will continuously change, with the distance being the farthest when in a horizontal state and the distance becoming closer when rising or falling. Figure 3 , Figure 4 This refers to the state where the motor drives the two seats to swing up and down. The small seat group 9 has three movements: "lifting", "swinging", and "sliding"; the large seat group 10 has two movements: "lifting" and "swinging".

[0048] Mode 2: By assembling and disassembling the small seat assembly mounted on the slide rod 5 in the armrest hole 5.2, seat plate hole 5.3, and slide groove 5.4, and by assembling and disassembling the large seat assembly 10 mounted on the rotating sleeve 6 in the side hole 6.3, three different entertainment modes can be achieved: electric small seat mode, electric large seat mode, and electric hybrid mode. The operating characteristics of the small seat assembly 9 and the large seat assembly 10 remain unchanged in different combination modes.

The pedals 9.2 can rotate left and right in the horizontal direction, and the seat plate 9.3 is rotatably connected to the seat plate hole 5.3 in the vertical direction. The seat plate 9.3, armrests 9.1, and pedals 9.2 constitute a child seat. It also includes two foot pedal links 9.4 and a guide rail with a groove 5.4. The guide rail is connected to the lower end of the slide rod 5 and extends out of the free end of the slide rod 5 along the direction of the slide rod 5.

The armrest frame includes a frame that is symmetrical and connected from left to right. The frame includes a bottom crossbar connected to the support rod. The two ends of the crossbar bend upward and extend to a first longitudinal bar and a second longitudinal bar. The first longitudinal bar is located in front of the second longitudinal bar. The height of the first longitudinal bar is lower than the height of the second longitudinal bar. A first connecting rod is connected between the first longitudinal bar and the second longitudinal bar. The upper end of the first connecting rod extends upward to form a second connecting rod.

[0050] Method 2: Mode 1: Figure 5 , Figure 6and Figure 7 This demonstrates the different motion states of the small seat group 9 and the large seat group 10 when the sliding sleeve 3 rotates upwards, downwards, and horizontally in "dual-seat mode." By separately limiting the sliding and rotation of the sliding sleeve 3, three different usage modes of the sliding sleeve 3 in "dual-seat mode" can be achieved: rotational movement, lifting and lowering, and rotation. When the sliding sleeve 3 rotates, the motion is similar to... Figure 5 , Figure 6 , Figure 7 Consistent; when the sliding sleeve 3 is restricted to rotation and only performs lifting and lowering movements, the small seat group 9 moves in the "lifting" and "sliding" motions, while the large seat group 10 only has the "lifting" motion; when the sliding sleeve 3 only rotates, the small seat 9 moves in the "swinging" and "sliding" motions, while the large seat group 10 only has the "swinging" motion.

[0051] Mode 2: When the "mixed mode" is used, that is, some positions have only small seat group 9 or large seat group 10, some positions have two seat groups (small seat group 9 and large seat group 10), and some positions are empty, the movement mode of small seat group 9 and large seat group 10 is the same as described above.

[0052] Example 3 (removing motor 14 and outer cover 2, using only an adult seat, such as...)
