[0002] In the current context of increasing demands for the quality of infant care by families, the safety and convenience of infant bathing has become a particular concern for parents. Most of the existing infant bathing auxiliary equipment on the market is designed to lie down, which provides stable support for infants. However, as children grow up, they begin to learn to stand and walk, and the infant bathing needs at this stage require standing auxiliary equipment to meet them.

[0003] In response to this demand, a new type of infant bathing aid has been designed, which consists of a base, a support column and a double-arm restraint device. The double-arm restraint device is specially designed as two arms that can be folded and unfolded, which can stably support infants and young children in the aid, allowing them to remain in a standing position, making it easier for parents to bathe them.

[0094] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0095] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0096] like Figures 1 to 6 As shown, the infant standing bathing aid 100 comprises a main base 10, a support column assembly 20, an upper base 30 and two foldable and unfoldable support arms 40. The main base 10 is used to be placed stably on the target ground, and the support column assembly 20 is a telescopic structure, which is longitudinally connected to the main base 10. The upper base 30 is connected to the upper end of the support column assembly 20, and the support arms 40 are rotatably connected to both sides of the upper base 30. The support column assembly 20 adjusts the telescopic degree to achieve the purpose of adjusting the height of the upper base 30, and then is suitable for infants of different heights.

[0097] Specifically, the main base 10 includes a mounting area f1 on the front side and a standing area f2 on the rear side. The design of the main base 10 provides a wide and stable support surface. The distinction between the mounting area f1 on the front side and the standing area f2 on the rear side ensures the stability and safety of the auxiliary device 100 during use. The lower end of the support column assembly 20 is connected to the mounting area f1, and the upper end of the support column assembly 20 is connected to the upper base 30. Two support arms 40 are axially connected to the two ends of the upper base 30. The support arm 40 is connected to the end 32 of the middle support member through a multi-angle limited rotation mechanism. The support arm 40 can adjust the expansion and contraction range, and then adjust the arc extension range and range of the restraining arc surface s.

[0098] The support arm 40 is connected by a multi-angle limited rotation mechanism, so that the support arm can be flexibly expanded and folded to adapt to the body shapes and posture changes of different infants and young children during bathing, providing a more personalized bathing experience.

[0099] The adjustment of the support arm 40 not only changes the arc extension amplitude of the restraining arc surface s, but also changes its range, so that the auxiliary device can be freely adjusted according to the movements of the infant to provide more fitting support and restraint.

[0100] The multi-angle limited rotation mechanism includes a rotation joint 60 and a locking assembly 70 disposed on the rotation joint 60. The rotation joint 60 allows the support arm 40 to rotate at multiple angles, providing a more detailed angle adjustment possibility; the locking assembly 70 ensures that the support arm 40 can be stably locked after being adjusted to the desired angle, preventing accidental sliding or rotation during use, thereby enhancing the safety of use. The user can quickly adjust the position of the support arm 40 by rotating the joint 60, and quickly lock it by the locking assembly 70, thereby improving the adjustment efficiency. The specific technical solution will be described below.

[0101] like Fig. 9 As shown, the upper base 30 includes a lower set 31 and a middle support member 32 which are sleeved on the upper end of the telescopic column 22 of the support column assembly 20. The telescopic column 22 passes through the lower set 31 and is fixed on the mounting seat in the middle support member 32. Through the close combination of the telescopic column 22 and the middle support member 32, the design of the upper base 30 forms a solid support system, providing a stable connection point for the support arm 40, and ensuring the reliability of the entire auxiliary device 100 in use.

[0102] A first arcuate surface s1 is provided on the inner side of the middle support member 32, and a second arcuate surface s2 is provided on the inner side of the two support arms 40. When the support arms are closed, the first arcuate surface s1 and the two second arcuate surfaces s2 together form a restraining arc surface s for restricting infants from escaping.

[0103] The design of the first and second curved surfaces provides a contact surface that matches the body curve of the infant, thereby enhancing the comfort of use and effectively limiting the range of movement of the infant during bathing to prevent the infant from slipping or falling off the aid.

[0104] The smooth transition between the curved surfaces s1 and s2 provides a better touch, making infants and young children feel more comfortable when bathing, and is also easy to clean and maintain.

[0105] The formation of the restraint arc surface s provides a safe protection area for infants and young children, reducing the risk of accidents that may occur during bathing. The closing and unfolding design of the support arm 40 makes it easy to adjust the restraint arc surface s, and parents can easily operate it according to the needs of infants and young children.

[0106] An auxiliary base assembly 50 consisting of three auxiliary bases e is disposed on the periphery of the installation area f1 of the main base 10. The addition of the auxiliary base assembly 50 significantly improves the stability of the entire bathing aid 100 on the ground, especially in a slippery bathroom environment.

[0107] The auxiliary base assembly 50 includes a front auxiliary base 1e, a left auxiliary base 2e and a right auxiliary base 3e. The front auxiliary base e1, the left auxiliary base e2 and the right auxiliary base e3 are respectively connected to the front, left and right sides of the main base 10 through connecting structures; the detachable design of the front auxiliary base 1e, the left auxiliary base 2e and the right auxiliary base 3e makes the assembly and disassembly of the total base K simple and quick, reduces the packaging volume during storage and transportation, and facilitates storage and transportation.

[0108] The auxiliary base assembly 50 and the main base 10 together constitute the entire total base K. The existence of the auxiliary base increases the contact area with the ground, reduces the risk of the bathing aid 100 tipping over, and the auxiliary base assembly 50 and the main base 10 work together to provide a more stable and comfortable bathing support base. In addition, the design of the auxiliary base assembly 50 enhances the structural strength of the entire total base K, so that it can better withstand the pressure caused by the activities of infants and young children during bathing.

[0109] The main base 10 includes a main bottom surface 11 , a main surface 12 and a peripheral side wall 13 ; and the peripheral side wall 13 includes three independent main connecting planes 14 .

[0110] The connection structure includes a connection groove g2 inside the auxiliary base e and a peripheral side wall where the main connection plane 14 of the main base 10 is located. Figure 7 As shown, the auxiliary base e includes an auxiliary bottom surface e1, an auxiliary surface e2 and an auxiliary connecting plane e3. An L-shaped connecting portion g1 is provided on the outer side of the auxiliary connecting plane e3. The L-shaped connecting portion g1 and the auxiliary connecting plane e3 form a connecting groove g2.

[0111] like Figure 8 As shown, the peripheral side wall where the main connecting plane 14 is located is inserted into the connecting groove g2 to connect the auxiliary base e with the main base 10.

[0112] The main connecting plane 14 cooperates with the connecting groove g2 formed by the L-shaped connecting portion g1 to achieve a stable connection between the auxiliary base e and the main base 10, thereby enhancing the stability of the entire bathing aid 100. The design of the L-shaped connecting portion g1 simplifies the assembly process of the auxiliary base e and the main base 10, making the assembly quick and without the need for additional tools.

[0113] The detachable design of the auxiliary base allows users to quickly remove and reinstall it as needed, providing greater flexibility and convenience.

[0114] The three independent main connecting planes 14 on the peripheral side wall 13 provide multiple connection points, increasing the overall strength and durability of the base structure.

[0115] After assembly, the design of the auxiliary base e makes the total base K more compact, optimizes space utilization, and makes the product more suitable for use in a home environment.

[0116] The main bottom surface 11 and the three auxiliary bottom surfaces e1 constitute the total bottom surface of the total base. Through the combination of the main bottom surface and the auxiliary bottom surfaces, the contact area with the ground is increased, thereby improving the stability of the entire bathing aid 100 and reducing the risk of tipping over.

[0117] The main surface 11 and the three auxiliary surfaces e2 smoothly transition and form the overall surface of the overall base. The smooth transition between the main surface 12 and the auxiliary surfaces e2 helps to evenly distribute the weight of the infant and water, reduce local stress concentration, and improve the durability of the product. The main connecting plane 14 and the auxiliary connecting plane e3 are closely attached to each other, making the connection between the two closer and the entire base more stable and compact.

[0118] In another implementation, the auxiliary base e and the main base 10 are separated when sold for easy storage and transportation, and after the user assembles them, the two are fastened and cannot be separated. Specifically, an undercut fastening assembly is provided between the auxiliary base e and the main connecting plane 14, including convex buckles c1 on both sides of the L-shaped connecting portion g1, and buckle holes c2 distributed at corresponding positions on the main connecting plane 14.

[0119] like Figures 15 to 17 As shown, when the peripheral side wall where the main connecting plane 14 is located is inserted into the connecting groove g2, the convex buckle c1 is embedded in the corresponding buckle hole c2, completing the locking of the auxiliary base e and the main base 10. The convex buckle c1 is embedded in the corresponding buckle hole c2, which not only limits the vertical separation of the L-shaped connecting portion g1 and the peripheral side wall of the main connecting plane 14, but also, the convex buckle c1 itself and the buckle hole c2 can be firmly positioned in the horizontal direction based on the slight deformation of the convex buckle c1 inserted into the buckle hole c2; that is, this technical means realizes the fastening between the auxiliary base e and the main base 10 in the vertical and horizontal dimensions, ensuring the firmness and stability of the entire base K after assembly.

[0120] Preferably, the front wall surface of the convex buckle c1 is an inclined surface, so as to facilitate guiding the convex buckle c1 to be buckled into the corresponding buckle hole c2 more easily.

[0121] The center of the installation area f1 is provided with an installation cavity f3, and the horizontal height of the standing area f2 is lower than that of the installation area f1; the surface of the standing area f2 is provided with an anti-slip mat. The installation cavity f3 is located at the center of the main base 10, providing a precise positioning point for the support column assembly 20, ensuring the structural stability and verticality of the entire auxiliary device 100.

[0122] The design of the mounting cavity f3 simplifies the installation process of the support column assembly 20 , eliminating the need for additional alignment or adjustment, thereby improving assembly efficiency.

[0123] The level of the standing area f2 is lower than that of the installation area f1. This design allows water in the installation area f1 to flow into the standing area f2 to avoid water accumulation in the installation area f1. It also helps to keep the center of gravity of the entire auxiliary device 100 low, thereby improving the overall stability.

[0124] The anti-skid mat on the surface of the standing area f2 provides additional grip for infants and young children, reducing the risk of slipping in a wet environment. Preferably, the design of the anti-skid mat takes into account the comfort of infants and young children when standing, and the soft material can provide better cushioning and sole support.

[0125] The support column assembly 20 includes a fixed column 21 and a telescopic column 22. A cavity is provided in the middle of the fixed column 21. The telescopic column 22 is inserted into the cavity and can move up and down relative to the fixed column 21. A control assembly 50 is provided between the fixed column 21 and the telescopic column 22, which can lock and unlock the telescopic column 22.

[0126] like Fig.10 and Fig.11 As shown, the control assembly 50 includes a button 51 disposed on the fixed column 21, a shift member 52 driven by the button 51, and a shift slot 53 disposed on the surface of the telescopic column 22. The user can precisely control the lifting and lowering of the telescopic column 22 through the button 51 to achieve fine adjustment of the height to accommodate infants of different heights.

[0127] The button 51 is easy to operate, so that the shift member 52 can be quickly locked or unlocked, which is convenient for the user to adjust the position of the telescopic column 22 as needed.

[0128] The bottom of the fixing column 21 is inserted into and fixed in the installation cavity f3 by a screw assembly. The fixing column 21 is fixed in the installation cavity f3 by a screw assembly, providing a stable base and ensuring the stability of the entire support column assembly 20.

[0129] The operating button 51 can make the shift member 52 fall into or leave the shift slot 53 , thereby locking or moving the telescopic column 22 relative to the fixed column 21 .

[0130] More specifically, Fig.10 and Fig.11 As shown, the button 51 is connected to the shift member 52 via a connecting rod 54. The shift member 52 includes a base 521 and a protrusion 522 on one side of the base 521, the protrusion 522 cooperates with the shift slot 53, and a connecting hole 523 is provided at the center of the base 521.

[0131] The first end of the connecting rod 54 is provided with a tilting portion 541, the second end of the connecting rod 54 is inserted into the connecting hole 523, the middle part of the connecting rod 54 is axially connected to the substrate p, and the substrate p is provided with a receiving groove p1 for receiving the connecting rod 54. The receiving grooves p1 are distributed along the length direction of the substrate p.

[0132] A first return spring 56 is disposed on the outer side of the base 521 and the inner wall of the fixing column 21 .

[0133] During actual use, the support column assembly 20 is in an initial position, wherein the telescopic column 22 is inserted into the cavity of the fixed column 21 and is maintained at a desired height by the control assembly 50 .

[0134] In order to adjust the length of the telescopic column 22, the user first needs to operate the button 51. Pressing the button 51 triggers the movement of the connecting rod 54, and the movement of the connecting rod 54 is transmitted to the shift member 52. The shift member 52 moves under the action of the connecting rod 54, and its protrusion 522 interacts with the shift groove 53 on the surface of the telescopic column 22. When the protrusion 522 of the shift member 52 matches the shift groove 53, the telescopic column 22 is locked in the current position.

[0135] If the length of the telescopic column 22 is to be adjusted, the protruding portion 522 of the shift member 52 needs to be disengaged from the shift slot 53 via the connecting rod 54 , thereby unlocking the telescopic column 22 .

[0136] Once the telescopic column 22 is unlocked, the user can manually move the telescopic column 22 up and down to adjust to a desired height or length.

[0137] During the adjustment process, the first return spring 56 is arranged between the outer side of the base 521 and the inner wall of the fixing column 21 to provide a restoring force for the shifting member 52, thereby ensuring that the shifting member 52 can quickly return to its initial position after being unlocked.

[0138] The upper base 30 is fixed to the upper end of the telescopic column 22, and the width of the middle support member 32 is greater than the width of the lower set 31; the upper base 30 is fixed at a higher position, and the middle support member 32 is wider, which can increase the stability of the entire bathing aid. The wider middle support member 32 can provide a larger support area, so as to better adapt to the body curve of infants and young children. The wider middle support member 32 helps to distribute the force more evenly when supporting infants and young children, reduce the local pressure on the infants and young children's body, and improve the comfort during bathing.

[0139] like Figure 12 to Figure 14 As shown, both sides of the middle support member 32 are connected to the support arm 40 via a rotation joint 60. The rotation joint 60 is provided with a locking assembly 70, which can lock or release the rotation of the support arm 40.

[0140] Specifically, the rotating joint 60 includes a sleeve 61 connected to the end of the middle support member 32 and a rotating shaft assembly 62 disposed in the support arm 40 . The rotating shaft assembly 62 penetrates into the sleeve 61 so that the support arm 40 can rotate relative to the middle support member 32 .

[0141] The locking assembly 70 includes a first annular tooth 71 disposed in the sleeve 61 and a second annular tooth 72 disposed on the shaft assembly 62. The first annular tooth 71 and the second annular tooth 72 cooperate with each other up and down. When the first annular tooth 71 and the second annular tooth 72 are engaged, the locking arm 40 is locked. When the second annular tooth 72 is separated from the first annular tooth 71, the arm 40 can rotate.

[0142] The rotating shaft assembly 62 includes an axle pin 621 and a cover portion 622 fixed to the upper end of the axle pin 621 . Second annular teeth 72 are arranged around the cover portion 622 .

[0143] More specifically, the upper end protrusion of the shaft pin 621 passes through the through hole of the shaft sleeve 61, and the upper end protrusion can move up and down relative to the through hole. A connecting hole for the fastener t to pass through is opened at the upper end of the cover 622, and the fastener t passes through the connecting hole, the through hole and the upper end protrusion to be fixedly connected.

[0144] A second return spring 63 is provided between the shaft pin 621 and the shaft sleeve 61. The function of the second return spring 63 during operation is to ensure that the shaft assembly 62 can automatically return to its initial position after the adjustment is completed.

[0145] The lower end of the shaft pin 621 is exposed from the lower end surface of the support arm 40 and forms a pressing portion; or the lower end of the shaft pin 621 is flush with the lower end surface of the support arm 40 .

[0146] The lower end of the axle pin 621 is placed in a cylindrical through cavity inside the shell of the support arm 40. When the expansion range of the support arm 40 needs to be adjusted, the lower end surface of the axle pin 621 is pushed upward, and the cover 622 fixed on the upper end of the axle pin 621 moves upward relative to the sleeve 61 to disengage the first and second annular teeth, thereby completing the unlocking. At this time, the support arm 40 can rotate relative to the shaft joint.

[0147] When it is necessary to lock a certain rotation angle of the support arm 40, after the rotation adjustment is completed, the pushing force applied to the lower end of the shaft pin 621 is removed, and the shaft pin 621 will move downward and reset under the action of the rebound force of the second reset spring 63, and the second annular tooth 72 at the lower end of the cover 622 engages and locks with the first annular tooth 71 on the sleeve 61, thereby locking the support arm 40 in the current position.

[0148] With the above technical means, the user can easily lock or unlock the support arm 40 by simply pushing the lower end surface of the shaft pin 621 upward or downward. The synergistic relationship between the rotating joint 60 and the locking assembly 70 provides a safe and flexible support system for the infant standing bathing aid, while ensuring the stability and durability of the structure, providing a convenient and safe bathing experience for parents and infants.

[0149] Preferably, the middle support member 32 and the two support arms 40 are both cylindrical hollow structures, and the middle support member 32 and the two support arms 40 are in an arc shape as a whole. The cylindrical hollow structure can reduce the overall weight while maintaining sufficient strength and rigidity. This design helps to improve the overall stability of the bathing aid. The arc-shaped design is more ergonomic, can better adapt to the body curve of infants and young children, and provide more comfortable support. This helps to reduce the discomfort of infants and young children during bathing.

[0150] Furthermore, the columnar hollow structure generally has better compression and bending resistance, which makes the entire bathing aid more durable and able to withstand the wear and tear of long-term use.

[0151] The peripheral side wall of the standing area f2 is an inclined arc-shaped wall, and the rear inclined wall u of the peripheral side wall and the arc-shaped front inclined surface of the front auxiliary base 1e have the same inclination amplitude, so that the upper edge u1 of the rear inclined wall u is flush with the highest point of the front inclined surface. Among them, the inclined wall design helps to guide water flow and reduce water accumulation, thereby reducing the risk of slipping in a slippery environment. The upper edge u1 of the rear inclined wall u is flush with the highest point of the front inclined surface, and the center of gravity of the entire base is more stable, and it is not easy for the front and rear ends to flip up and down during use, which can effectively ensure the stability of the entire base K during use.

[0152] The left auxiliary base 2e, the right auxiliary base 3e and the mounting cavity f3 are located on the same straight line, and the auxiliary surfaces of the left and right auxiliary bases are connected to the front surface 131 of the side wall 13 of the main base 10. This structural design may increase the overall strength and durability of the base, so that it can better withstand the pressure and wear during use. In addition, it can also ensure the continuity of the entire base and make the appearance curve more smooth and beautiful.

[0153] Preferably, the restraining arc surface s is located directly above the standing area f2. This orientation relationship can more effectively limit the range of movement of infants and young children, and effectively and comfortably restrain infants and young children.
