[0034] References in this specification to "one embodiment," "an example," or "an example" mean that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment disclosed herein. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0035] Example:

[0036] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The figure shows a bouncer designed for infants and young children, providing them with a space for exercise and play. The bouncer includes a stable seat frame and a bounce chassis 300 suspended from the seat frame via multiple elastic retractable components 400. The seat frame is placed on the ground, providing a solid mounting base to ensure the stability and safety of the bounce chassis. In this example, the elastic retractable components 400 can be elastic bands, springs, or a combination of the two. This design can provide the bouncer with better elasticity and cushioning during use, providing a more comfortable and safe experience.

[0037] The seat frame's outer contour on the ground is larger than that of the bouncing chassis 300, and the frame's outer contour surrounds the bouncing chassis 300, forming a circular structure. This design maintains a certain distance between the seat frame and the bouncing chassis 300, with the spacing being approximately equal around the perimeter. This provides stable and uniform support for the seat frame, ensuring it is less likely to tilt or tip over during use.

[0038] See also Figure 1 The seat frame includes a base frame 110, a plurality of support columns 120, and a plurality of reinforcing connectors 200. The plurality of support columns 120 are evenly distributed around the base frame 110 and are erected on the base frame 110. The bottoms of the support columns 120 are fixed to the base frame 110 by bolts, plugs, or other detachable connections to facilitate disassembly and maintenance.

[0039] The reinforcing connector 200 covers the connection between the support column 120 and the bottom frame 110, aiming to strengthen the connection between the support column 120 and the bottom frame 110, while also protecting the connection and extending its service life. The reinforcing connector 200 has a support surface facing the ground, which is equipped with a corresponding anti-slip pad 230 for contact with the ground.

[0040] In some embodiments, as Figure 4 As shown, the reinforcing connector 200 includes an outer shell 210 and a bottom cover 220. One side of the outer shell 210 is provided with a through-hole 211 for mounting the support column 120, and the other opposite side is provided with an opening. Two opposing sides of the opening are each provided with a notch 212 for passing through the base frame 110, and the middle of the opening intersects and communicates with the bottom of the through-hole 211. The bottom cover 220 covers the opening and forms a mounting cavity between the bottom cover 220 and the outer shell, which is used to mount and secure the connection between the support column 120 and the base frame 110. The bottom surface of the bottom cover 220 opposite the opening forms a support surface, and an anti-slip pad 230 is provided on the bottom surface of the bottom cover 220. After the bottom cover 220 is connected to the opening, it fills the perimeter of the notch 212 on the side wall of the opening. The base frame 110 extends along the top surface of the bottom cover 220, and protrudes through the notch 212 on both sides. In this way, when the bottom frame 110 is subjected to pressure, the pressure will directly act on the bottom cover 220 and be evenly dispersed on the anti-slip pad 230 of the bottom cover 220, thereby enhancing the overall stability and bearing capacity.

[0041] The bouncing chair provided in this embodiment significantly increases the friction between the support surface and the ground by providing an anti-slip pad 230 on the support surface of the reinforced connector 200. This design prevents horizontal displacement of the bottom frame 110 even if the bouncing chassis 300 experiences significant wobbling during use, effectively eliminating safety hazards associated with significant wobbling or placement on uneven surfaces. This not only improves the stability of the bouncing chair during use but also enhances its overall safety, providing a safer and more comfortable exercise and play environment for infants and young children.

[0042] In some embodiments, as Figure 4 As shown, the bottom surface of the bottom cover 220 is provided with a receiving groove 221. The thickness of the anti-slip pad 230 is greater than the depth of the receiving groove 221, so that the anti-slip pad 230 partially embeds within the receiving groove 221. The anti-slip pad 230 is made of a material with a certain degree of elasticity. When the bouncing chassis 300 is in use, the anti-slip pad 230 not only increases friction with the ground but also absorbs some energy, reducing impact on the seat frame. A portion of the anti-slip pad 230 is located within the receiving groove 221 for easy installation, while the other portion is located outside the receiving groove 221, providing a certain amount of elastic deformation to cope with wear during use and extend its service life.

[0043] The technical effect of this design is that the structure of the anti-slip pad 230 can effectively reduce the impact force generated by the bouncing movement, ensuring the safety of infants and young children when playing. In addition, through the reasonable structural layout and material selection, the overall stability and comfort of the bouncing chair are improved, creating a safer environment for users.

[0044] In some embodiments, as Figure 4 As shown, the bottom cover 220 and the outer shell 210 are connected by multiple threaded fasteners. The bottom cover 220 is provided with multiple mounting holes 222 for the threaded fasteners to pass through. The multiple mounting holes 222 are distributed around the periphery of the receiving slot 221. For example, the threaded fasteners are bolts. Multiple internally threaded studs are provided within the outer shell 210. One end of the bolt passes through the mounting holes 222 of the bottom cover 220 and connects with the internally threaded studs within the outer shell 210, ensuring the structural strength and stability.

[0045] In a specific implementation, the bottom cover 220 is located on the inner and outer sides of the bottom frame 110 and is fixed by two bolts respectively. These bolts arranged on the inner and outer sides of the bottom frame 110 not only effectively position the bottom frame 110, but also play a role in strengthening the bottom frame and improving the stability of the overall structure.

[0046] In some embodiments, the area of ​​the anti-slip pad 230 accounts for at least 60% of the support surface area of ​​the reinforcing connector 200. Specifically, the area of ​​the anti-slip pad 230 can account for 60%, 70%, 80%, 90%, or 100% of the support surface area of ​​the reinforcing connector 200. Furthermore, the area of ​​the anti-slip pad 230 is at least 4 square centimeters, and specifically can be 4 square centimeters, 8 square centimeters, 12 square centimeters, 16 square centimeters, 20 square centimeters, or 24 square centimeters. Furthermore, in the circular design of the bottom frame 110, the width of the anti-slip pad 230 is greater than the width of the bottom frame 110. This design can provide better support and friction, thereby enhancing safety.

[0047] In other alternative embodiments, such as Figure 5 and Figure 6 As shown, the area of ​​the anti-slip pad 230 completely covers the support surface area of ​​the reinforcing connector 200, that is, the area of ​​the anti-slip pad 230 completely covers the bottom surface of the bottom cover 220. The bottom cover 220 and the outer shell 210 are connected by multiple threaded fasteners. The combination of the bottom cover 220 and the anti-slip pad 230 is provided with multiple mounting holes 222 for the threaded fasteners to pass through, ensuring a tight connection of the entire structure.

[0048] This design effectively improves the safety and stability of the bouncing chair, ensuring that it can withstand a certain amount of pressure and impact when used by infants and young children. At the same time, it increases the contact area with the ground and improves the anti-slip effect.

[0049] In some embodiments, the base frame 110 includes a plurality of curved tubes 111, which are connected end to end to form a single, integrated base frame 110. For example, the base frame 110 is circular and is composed of three curved tubes 111 with a curvature of π / 3. For example, the ends of the curved tubes 111 are connected by splices or connectors. In the radial direction of the base frame 110, the width of the anti-slip pad 230 is greater than the width of the curved tubes 111 to ensure sufficient support and friction.

[0050] Each arc-shaped tube 111 is provided with a plug connector 112 corresponding to the support column 120, and multiple plug connectors 112 are connected to corresponding multiple support columns 120. For example, the plug connector 112 is vertically arranged on the plane corresponding to the arc-shaped tube 111, and the plug connector 112 and the support column 120 are both tubular structures. The plug connector 112 is integrally connected to the middle part of the arc-shaped tube 111, for example, by welding. The diameter of the plug connector 112 can be larger or smaller than the diameter of the pipe mouth of the support column 120, so that the plug connector 112 can be inserted into the pipe mouth of the support column 120 from the side, or the pipe mouth of the support column 120 can be inserted into the pipe mouth of the plug connector 112. In addition, a pin is provided on the overlapping section where the plug connector 112 and the support column 120 are connected. The pin passes through the pipe wall of the plug connector 112 and the support column 120 along the radial direction, thereby achieving fixation after plugging.

[0051] The reinforcing connector 200 is wrapped around the plug connector 112 of the arc-shaped tube 111. Specifically, the outer shell 210 and the bottom cover 220 form a housing cavity, and the arc-shaped tube 111 is disposed within the housing cavity. The two ends of the arc-shaped tube 111 extend from the notch 212, and the plug connector 112 is disposed within the through hole 211 and partially extends out of the through hole 211. The bottom of the support column 120 is inserted into the plug connector 112 within the through hole 211, ensuring a stable and reliable connection.

[0052] In some embodiments, the anti-slip pad 230 has two opposing surfaces along its thickness. One surface is connected to the support surface of the reinforcing connector 200, and the other surface is provided with concave and convex anti-slip patterns. In some examples, the anti-slip patterns can be in the form of elongated strips, circles, or crosses, and are evenly distributed across and cover the entire bottom surface of the anti-slip pad 230. It is worth noting that the anti-slip patterns on the bottom surface of the anti-slip pad 230 are not shown in the figures.

[0053] In some embodiments, the anti-slip pad 230 has two opposing surfaces along its thickness: one surface is connected to the support surface of the reinforcing connector 200, and the other surface is provided with at least one anti-slip suction cup. In this example, a single, larger diameter anti-slip suction cup can be provided on the bottom surface, or four anti-slip suction cups arranged in a 2x2 pattern can be provided. The tops of these anti-slip suction cups are integrally or detachably connected to the anti-slip pad 230. The anti-slip suction cups, as an optional accessory for the anti-slip pad 230, can enhance the stability of the bounce chair on a tiled bottom surface, ensuring safety during use.

[0054] In some embodiments, the anti-skid pad 230 includes any one of a rubber pad, a silicone pad, or a polyurethane pad. In some examples, the anti-skid pad 230 can be a rubber pad, a silicone pad, or a multi-layer pad made of the above materials to provide better anti-skid effect and durability.

[0055] In some embodiments, as Figure 7 、 Figure 8 and Figure 9The figure shows a bouncing chair, which also includes a tread cloth mounted on a base frame. The tread cloth includes a main tread cloth body 500 and multiple fixed side bands 600 arranged around the main tread cloth body 500. While the main tread cloth body 500 is circular in shape, it can also be polygonal, trapezoidal, or other irregular shapes, without limitation. Three fixed side bands are provided, evenly spaced around the circumference of the main tread cloth body. The fixed side bands comprise two layers of fabric connected at their edges. The fixed side bands 600 have a specific length and width. Along their length, one end of the fixed side band 600 is connected to the main tread cloth body 500, and the other end is used to connect to the base frame 110. The end connected to the main tread cloth body is the first end, while the end connected to the base frame is the second end. The first end is wider than the second end. The first end is connected to the main tread cloth body 500, and the second end is provided with a button assembly 700. The second end can be fastened to the base frame by the button assembly to form a belt sleeve. Specifically, the second end can be tied into a belt sleeve with an accommodating space, the perimeter of the accommodating space is greater than the perimeter of the cross section of the bottom frame, so that the belt sleeves of multiple fixed edges can provide corresponding accommodating spaces for the bottom frame to pass through.

[0056] The tread cloth of this embodiment, on the one hand, avoids the occurrence of multiple corners at the second end by designing the fixed edge band 600 to be wider at the first end and narrower at the second end, potentially eliminating any corners. Thus, during the manufacturing process, after sewing the three edges of the fixed edge band 600, the user can simply reach into the pocket reserved at the first end, grasp the second end, and then flip it outward and back to the front, without the need for tools, thereby improving production efficiency. Furthermore, the fixed edge band 600 eliminates the conventional Velcro assembly and instead utilizes a button assembly 700. The button assembly 700 can be installed using a crimping machine, eliminating the need for manual sewing and further improving production efficiency.

[0057] In some embodiments, the two layers of fabric of the fixed sideband 600 are respectively a top layer and a base layer, both of which are trapezoidal in shape and can be made of different materials. The top layer and base layer are stacked together, overlapping, and connected by sewing at their periphery, forming a pocket at the first end of the fixed sideband 600. The pocket is connected to the edge of the main body of the tread cloth 500.

[0058] In some alternative embodiments, when the outer fabric and the base material are made of the same material, one side of the outer fabric and the base material can be integrally connected and formed into two sides by folding.

[0059] In some embodiments, the width of the fixing side band 600 gradually decreases from the first end to the second end, so that the edge of the fixing side band 600 is continuous and easy to process.

[0060] In some embodiments, the bottom surface of the trampoline is provided with suction cups for adsorbing and fixing to a smooth surface, such as a tile surface. The suction cups on the trampoline are fixed to the ground, which can also increase the connection strength between the trampoline and the ground to a certain extent, thereby reducing the possibility of the trampoline shifting.

[0061] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are included within the scope of the claims.
