Description

[Technical Field]

[0001] The present invention relates to an infant bathing aid that supports an infant so that the infant can remain upright during bathing. [Background technology]

[0002] Generally, infants aged 5 to 24 months are unable to stand up by themselves or maintain an upright position for a long period of time. Therefore, when bathing or washing away feces after a bowel movement, parents have to maintain the infant's position with one hand while operating the shower nozzle and washing with the other, which is inconvenient.

[0003] In order to solve these problems, many bathing aids have been proposed to support babies and keep them upright while bathing. As an example of the prior art, the structure of the baby bathing aid described in Korean Patent Publication No. 10-2022-0131036 will be described in detail below with reference to Figures 1 and 2.

[0004] The conventional bathing aid includes an upper body part 10 that supports the upper body of the baby to keep it upright, a pair of armrests 20 formed on both sides of the upper body part 10 to support the baby's arms and prevent the baby from slipping off, a lower body part 30 formed below the upper body part 10 to prevent the bathing aid from tipping over, and a height adjustment part 40 that allows the height of the upper body part 10 to be adjusted relative to the lower body part 30. The armrests 20 can rotate inward and outward, but by restricting their movement so that they can only rotate outward, the armrests 20 do not spread out uncontrollably, allowing the baby to lean on them stably.

[0005] However, conventional bathing aids have the problem that when the armrest 20 is rotated inward, a continuous loud impact noise is generated, and when the armrest 20 is rotated outward, the parent or guardian must exert a considerable amount of force to release the restriction on the operation of the armrest 20.

[0006] Specifically, conventional bathing aids must be able to narrow the armrest 20 inward to fit the baby's physique, while preventing it from spreading outward, but this requires an angle adjustment device made up of a pair of gears and a compression spring, which makes it impossible to avoid the generation of continuous impact noise. As shown in Figure 2, conventional bathing aids have fixed teeth 15 formed integrally with the upper body 10, and rotating teeth 25 connected to them are formed to move in conjunction with the armrest 20, and a compression spring 27 is interposed in the axial direction of the rotating teeth 25, so that the connection can be selectively maintained depending on the direction of rotation of the rotating teeth 25. While the armrest 20 rotates horizontally, the fixed teeth 15 and the rotary teeth 25 that control the rotation reciprocate relative to each other in an axial direction perpendicular to the rotation direction. Therefore, in order to control the rotation using the teeth of the armrest 20, the only option is to rely on the compression spring 27 that presses the teeth in the axial direction. Due to the structural limitations described above, when the armrest 20 rotates inward, the teeth collide with the compression spring 27 as the rotary teeth 25 reciprocates in the axial direction, which causes a continuous loud impact noise.

[0007] In particular, for the safety of the baby, the armrest 20 must not unfold on its own, so that when the baby leans on the armrest and the weight of the baby acts in the unfolding direction of the armrest 20, a strong compression spring 27 must be used to keep both teeth connected sufficiently, which causes a problem of making a louder impact noise. Moreover, since the impact noise is generated close to the baby's ear, the baby's sense of rejection is more severe.

[0008] In addition, after taking a bath, in order to unfold the armrest 20, the connection between the rotary teeth 25 and the fixed teeth 15 must be released. The source of the force that connects the two teeth is the elastic force of the compression spring 27. As a result of using a strong compression spring 27 as described above, it is very difficult to release the rotation restriction of the armrest 20, which requires a force that is greater than the elastic force of the compression spring.

[0009] In addition, conventional bathing aids have serious problems, such as when the armrest 20 is rotated inward, the baby's skin is pulled into the gap between the upper body part 10 and the armrest 20, or the skin is pressed against it, causing bruises and other serious injuries. Specifically, as shown in Fig. 1, the mating part A of the upper body part 10 and the armrest 20 interacts like a pressure roller, drawing in and pressing against an object in contact with it into the mating part A by friction when the armrest 20 is rotated inward. Therefore, when the armrest 20 is rotated inward with the baby's skin in close contact with the mating part A, the action of the mating part A pulls the baby's skin into the gap, and because the gap is very narrow, the skin is pressed against it tightly, causing bruises and other serious injuries.

[0010] Meanwhile, some bathing aids are equipped with means for attracting the baby's attention to prevent the baby from feeling uncomfortable or losing its posture when using them. Therefore, while conventional bathing aids are equipped with a display unit, a bubble generator, etc., there are serious problems in that if the baby shows no interest in the means for attracting the baby's attention or if the parent dislikes the means, they cannot be replaced with another one, and even if the baby loses interest after repeated use, they cannot be replaced with another one. Furthermore, since the means are built into the bathing aid, they must be purchased together even when they are not being used, which significantly increases the purchase cost.

[0011] Furthermore, in order to attract the interest of babies aged 5 to 24 months who use bathing aids, it is generally recommended to provide visual and tactile stimulation through direct hand play. However, the display unit can have a harmful effect on babies of this age, and therefore cannot be said to be a safe means of visual stimulation. In addition, the bubble generator is generated in the armrest 20, which is located under the baby's armpit, and is therefore difficult to reach and touch directly, and bubbles can get into the baby's mouth. Considering these factors, there are problems in that this is not a safe and effective means of attracting interest.

[0012] On the other hand, conventional bathing aids have a drain hole only in the step, which is the part of the lower body part (30) that the baby steps on. Because the gap between the bottom of the bathtub or tub and the bottom of the lower body part (30) is very narrow, washing water and foreign matter such as feces that flows into the inside of the step cannot be smoothly drained. A large portion of the washing water is discharged to the open rear part of the lower body part (30). However, if the bathing aid is tilted forward due to the slope of the bottom of the bathtub or tub, the washing water cannot be drained quickly. Furthermore, foreign matter such as feces cannot be drained quickly and ends up on the baby's feet inside the step, or, even if it is drained through the drain hole, the gap between the step and the bottom is too narrow to get on the bottom of the bathtub or tub or the bottom of the lower body part (30). This creates serious hygiene problems, and there is also the problem that the baby may slip in the washing water while it is still pooling, causing a safety accident.

[0013] Furthermore, since the bathing aid is used in the bathroom, it is generally stored on the bottom of the bathroom or bathtub, but since the bathing aid is quite large compared to the small area of ​​the bathroom, it can be inconvenient when using the bathroom for other purposes due to the space it occupies, and there are problems such as the retention of moisture on areas that come into contact with the bottom of the bathtub, such as the bottom of the lower body, which can lead to the growth of mold, etc. Furthermore, the bathing aid is often brought into a living room or room other than the bathroom and used for other purposes, such as supporting an infant when changing diapers or clothes, but due to the above-mentioned storage method, moisture on the bottom of the lower body does not dry well, causing inconvenience and sanitary problems as water drips onto the floor of the living room or room when the bathing aid is moved.

[0014] On the other hand, even though the outward rotation of both armrests is restricted to prevent the baby from falling off the upper body part, as the baby's weight is excessively concentrated on the ends of the armrests, the baby's flexible upper body may fall into the space between the ends of the armrests, or if the baby's lower body muscles are not yet developed and they sit down, the baby's neck may slip through the space between the ends of the armrests, causing the baby to fall off the upper body part and fall and be injured.

[0015] Furthermore, the armrest is hinged to the upper body and pivots, necessitating the formation of an operating hole. However, as shown in Figure 1, the armrest is formed in a horizontal structure, and water that enters the armrest through the operating hole is not naturally drained out. This not only requires tilting the bathing aid to drain the water, but also makes the water get deeper. If water remains inside the armrest, it not only makes a water-spraying noise inside the bathing aid, but also causes hygiene problems, such as mold growth inside. Summary of the Invention [Problem to be solved by the invention]

[0016] The present invention aims to solve the problems of the conventional baby bathing aids as described above. In the configuration of the rotation control means for restricting the operation of both armrests provided in the bathing aid, instead of relying on a strong compression spring acting perpendicular to the rotation plane of the armrest, the rotation control means is configured to interact on the same plane so that the external force for rotating the armrest can be used as the control force. This eliminates the need for a strong compression spring, thereby reducing noise and allowing the rotation restriction to be released with less force. By providing a skin protection means, it is possible to prevent injury caused by the baby's skin being pulled into or pressed into the gap between the upper body part and the armrest due to the movement of the mating part of the upper body part and the armrest when the armrest is rotated inward. By making the play means detachable, it is possible to replace it with a safe play means preferred by the baby or guardian, or to solve the problem of not being able to purchase the bathing aid separately. Instead of a configuration in which a drain hole is formed only in the step, a drain outlet and drain are provided at the boundary located at the front or side of the step. The step stool has an outlet passage to quickly drain foreign matter such as washing water and feces that enters the inside of the step stool. A removable anti-slip pad is provided on the upper part of the lower body to prevent injuries caused by the baby slipping and falling from the upper part of the lower body. The hanging means allows for easy storage inside the bathroom, eliminating the need to store it on the bottom of the bathroom or bathtub, thereby efficiently using bathroom space and allowing for easy drying and hygienic use. When the armrests are fully folded, the gap between the anti-slip sections formed on the ends of the armrests is set to 3cm or less, which is too small for the baby's neck, the narrowest part of the upper body, to pass through, completely preventing the baby from coming off. This prevents the baby from coming off between the ends of both armrests even if the baby's weight is excessively concentrated on the ends of the armrests or if the baby's lower body muscles are not yet developed and they sit down. The armrests have partitions to prevent water from flowing inside, minimizing the water inflow area. A drain is provided to discharge water that has entered inside, preventing water from remaining inside the armrests.The purpose of the invention is to solve the problem of water noise or mold growth inside. [Means for solving the problem]

[0017] The baby bathing aid according to the present invention, which allows a caregiver to keep a baby standing upright without tipping over when bathing the baby, comprises an upper body part supporting the baby's upper body, armrests supporting the baby's arms or sides to keep the baby standing upright, and a lower body part formed below the upper body part to support the baby's lower body, the armrests being rotatably formed on the upper body part and capable of narrowing inward or widening outward, and comprising a rotation control means for restricting rotation in one of the two directions, the rotation control means comprising a fixed ring, a rotating ring, and a stopper interposed between the fixed ring and the rotating ring and performing a constriction action, the constriction action being achieved by a process in which the gap between the pressing areas of the fixed ring and the rotating ring narrows, or the gap between both pressing areas of the stopper widens, or both changes occur simultaneously, the stopper making point contact, line contact, or surface contact with the fixed ring and the rotating ring, and the stopper being formed from a single body. the armrest is hinged to the upper body portion and has a rotation shaft therein, and the armrest and the rotation control means are selectively linked to each other depending on the axial position of the rotation shaft; an engagement groove is formed at the rotation center of the rotation wheel; and an engagement protrusion is partially formed on the outer circumferential surface of the rotation shaft, and the engagement groove and the engagement protrusion are selectively coupled to each other depending on the axial position of the rotation shaft.

[0018] In addition, a skin protection means is further provided to prevent the baby's skin from being pinched in the gap between the upper body part and the armrest, or to prevent the baby's skin from being pressed against the gap even if it is positioned therein. The skin protection means is a space portion of a predetermined shape for preventing the skin from being pinched, formed in either or both of the armrest and the upper body part, and the skin protection means is a blocking member that blocks part or all of the gap between the upper body part and the armrest.

[0019] In addition, an outlet is formed at the front or side of the platform formed on the lower body portion, or at the boundary between the front and side, and an outlet passage connected to the outlet is formed on the bottom surface of the lower body portion.

[0020] The baby bathing aid is further characterized in that a play means is detachably provided on the baby bathing aid, the play means is installed by a support means that is detachably attached to the baby bathing aid, the support means is detachable from the play means, and the support means is rod-shaped or table-shaped.

[0021] In addition, by forming at least one hanging means, the towel can be hung on an existing bathroom structure such as a towel rack or towel shelf or on a hanging member formed on the wall of the bathroom for storage, and the hanging means is characterized by being formed in a groove shape or a hook shape.

[0022] The anti-slip pad may also include an anti-slip pad that prevents the baby from slipping on the upper part of the lower body part, the anti-slip pad being made of flexible resin, the anti-slip pad being formed in a shape corresponding to the shape of the step stool, a protrusion formed on the upper surface of the anti-slip pad and a recess formed on the bottom surface of the anti-slip pad, and an attachment / detachment means that allows the anti-slip pad to be attached to and detached from the lower body part, the attachment / detachment means being an adsorption plate formed on the bottom surface of the anti-slip pad, or including a fixing protrusion formed on the bottom surface of the anti-slip pad and a fixing groove formed on the step stool.

[0023] On the other hand, it is characterized in that it includes anti-slip parts formed at the ends of the armrests to prevent the baby from slipping out between the armrests, and the distance between the anti-slip parts on both sides is 3 cm or less when the armrests on both sides are fully closed.

[0024] Meanwhile, the armrest includes a blocking means for blocking water from flowing inside or a discharge means for discharging water that has flowed inside, the blocking means for blocking water from flowing inside is a partition wall, and the discharge means for discharging water that has flowed inside is a drain hole formed on the bottom surface of the armrest, and the drain hole may be formed in multiple numbers or may be formed at the lowest position in the space partitioned by the reinforcing ribs. [Effects of the Invention]

[0025] The baby bathing aid of the present invention is configured with a rotation control means that interacts on the same plane, so that the rotation of the armrest can be controlled using an external force that rotates the armrest without using the elastic force of a strong compression spring. As a result, it not only reduces noise when the armrest is operated and eliminates the baby's refusal due to the excessive noise, but also has the effect of being able to release the rotation restriction of the armrest with a small force.

[0026] In addition, the baby bathing aid according to the present invention has a space for preventing skin pinching at the joint of the upper body and the armrest, which minimizes the baby's skin from being pulled in when the armrest is rotated inward. Even if a part of the skin is pulled in, it will not be pressed so tightly that it will be injured. The installation of a blocking member fundamentally prevents the baby's skin from being pulled in, so there is no risk of bruising or other injuries. Therefore, the baby can use it safely and will not feel any refusal to use it.

[0027] In addition, since the play means is detachable, it can be efficiently replaced with the play means most preferred by the baby or guardian, and the consumer can purchase a bathing aid without the play means, which not only has the effect of reducing the purchase cost of the bathing aid, but also allows the user to select a play means that is safe and stimulates the visual and tactile senses and is generally recommended for the age of the baby using the bathing aid.As the baby uses the bathing aid, they can play with the play means by seeing it with their eyes and touching it with their hands, which not only attracts the baby's interest, but also has the effect of developing their brain through the visual and tactile stimulation and small muscles through the act of touching it with their hands.

[0028] In addition, the bathing aid according to the present invention has a sufficiently large drainage opening at the boundary located at the front or side of the step, which allows washing water and foreign objects such as feces that flow into the inside of the step to be smoothly drained in a short time, preventing hygienic problems such as foreign objects such as feces getting on the baby's feet inside the step or being discharged through the drainage hole of the step and getting on the bottom of the bathroom or bathtub or the bottom of the lower body, and also minimizing the phenomenon of the baby slipping due to accumulated washing water.

[0029] In addition, the bathing aid can be easily stored in the bathroom using the hanging means, allowing for efficient use of bathroom space, and is easy to dry and does not develop mold, making it hygienic to use.When the bathing aid is brought to a room other than the bathroom and used for other purposes, such as changing diapers or clothes or supporting an infant, moisture on the bottom of the lower body dries quickly, preventing the inconvenience and hygienic problems that would occur if water were to drip onto the floor of the room or living room while the aid is being moved.

[0030] In addition, a removable anti-slip pad is formed on the upper part of the lower body part, which minimizes the baby's slipping on the lower body part due to accumulated washing water.Furthermore, the anti-slip pad can be easily attached and detached using the attachment and detachment means for easy cleaning, which has the effect of preventing the formation of water stains and mold.

[0031] In addition, when both armrests are fully narrowed, the gap between the anti-slip parts formed on the ends of the armrests is less than 3cm, which is too narrow for the baby's neck to pass through. This means that the baby's neck, the thinnest part of the baby's upper body, cannot pass through. This completely prevents the baby from escaping through the gap between the armrests, even if the baby's weight is excessively concentrated on the ends of the armrests or the baby's lower body muscles are not yet developed and sits down.

[0032] Furthermore, partition walls are formed on the upper and lower sides of the interior of the armrest so that their ends touch and overlap each other, fundamentally preventing water that has flowed into the operating hole of the armrest from flowing into other compartments and minimizing the area through which water flows in. Furthermore, a drain hole is formed on the bottom of the armrest, so even though the armrest is formed in a horizontal structure, water that has flowed in through the operating hole is naturally discharged without remaining inside the armrest, preventing the inconvenience to users caused by the sound of water inside and preventing sanitary problems such as mold growth inside.

DETAILED DESCRIPTION OF THE INVENTION

[0034] The baby bathing aid according to the present invention has a pair of armrests 200 formed on both sides of an upper body part 100, and a lower body part 300 and a height adjustment part 400 formed below the upper body part 100. Each component of the bathing aid according to a preferred embodiment of the present invention will be described in detail below with reference to Figures 3 to 20.

[0035] The upper body part 100 of the bathing aid according to the present invention supports the upper body of the baby so that the baby can maintain an upright position, and a pair of armrests 200, which are hinged and rotate on both sides of the upper body part 100, support the baby's arms or sides and prevent the baby from slipping off the upper body part 100. Here, since the upper body part 100 and the armrests 200 come into contact with the baby's body, they are preferably formed in a soft curved shape, and the surface material can be selected from hard and soft materials. The armrests 200 can be rotated to narrow inward or widen outward, and a rotation control means 500 that allows selective rotation in at least one of the two directions can be formed in conjunction with the armrest 200 to restrict its operation. Preferably, the rotation control means 500 restricts the outward rotation of the armrest 200 so that the armrests 200 do not unintentionally widen and the baby can rest stably on the armrest 200, and allows the armrests 200 to rotate freely inward, narrowing the width of the armrests 200 to suit the baby's physique. Meanwhile, the rotation of the armrests 200 in both directions can be controlled according to the user's preference.

[0036] To explain the configuration of the rotation control means 500 in more detail, the rotation control means 500 interlocked with the armrest 200 includes fixed rings 510 formed on both sides of the upper body part 100, a rotating ring 520 located on the same plane as the fixed ring 510 and interlocked with the armrest 200, stoppers 550, 560, 570 interposed between the fixed ring 510 and the rotating ring 520 and formed to limit and release the relative rotation between the fixed ring 510 and the rotating ring 520, and position setting means for controlling the operating range of the stoppers 550, 560, 570 so that the stoppers 550, 560, 570 move within a certain range, and may further include contact maintaining means for maintaining contact of the stoppers 550, 560, 570 with the fixed ring 510 and the rotating ring 520 in the direction of the limit.

[0037] The restriction is achieved by a constriction action between the fixed ring 510 and the rotating ring 520 and the stoppers 550, 560, and 570 interposed therebetween. More specifically, when the rotating ring 520 is rotated in a direction that restricts the relative rotation of the rotating ring 520 with respect to the fixed ring 510, the relative distance between the pressing areas of the fixed ring 510 and the rotating ring 520 and the pressing areas of the stoppers 550, 560, and 570 narrows, i.e., the distance between the pressing areas of the fixed ring 510 and the rotating ring 520 narrows, or the distance between the pressing areas of the stoppers widens, or both changes occur simultaneously, resulting in a constriction action in which the pressing areas of the stoppers 550, 560, and 570 interposed between the fixed ring 510 and the rotating ring 520 press against the pressing areas of the fixed ring 510 and the rotating ring 520, respectively, restricting the relative rotation of the rotating ring 520 with respect to the fixed ring 510.

[0038] Meanwhile, if the stoppers 550, 560, 570 are spaced apart from the fixed wheel 510 and the rotating wheel 520 in the direction of restriction during the restriction operation without contacting them, the restricting action cannot be performed immediately, and the rotating wheel 520 may rotate a little before the restricting action is performed, or in some cases, the restricting action may not be performed effectively. In order to minimize this, it is preferable to provide a contact maintaining means for maintaining the stoppers 550, 560, 570 in contact with the fixed wheel 510 and the rotating wheel 520 in the direction of restriction.

[0039] In addition, by forming a concave-convex portion on at least one of the pressing areas of the fixed ring 510, the rotating ring 520, and the stoppers 550, 560, and 570 during the restricting operation, slippage of the stoppers 550, 560, and 570 can be prevented, and the constriction effect can be made more robust. The concave-convex portion is a protrusion formed on either side of the pressing area or a combination of a protrusion and a groove formed on both sides of the contact surface, and its shape is not limited to a sawtooth shape, a triangle, a semicircle, a diagonal line, a dot shape, etc.

[0040] The release is achieved by releasing the constricted state. More specifically, when the rotating wheel 520 is rotated in a direction that releases the restriction on the relative rotation of the rotating wheel 520 with respect to the fixed wheel 510, the relative distance between the pressing areas of the fixed wheel 510 and the rotating wheel 520 and the pressing area of ​​the stopper increases, i.e., the distance between the pressing areas of the fixed wheel 510 and the rotating wheel 520 increases, or the distance between the pressing areas of the stopper decreases, or both changes occur simultaneously, causing the pressing areas of the stopper interposed between the fixed wheel 510 and the rotating wheel 520 to release from the pressing contact state with the pressing areas of the fixed wheel 510 and the rotating wheel 520, respectively, thereby releasing the restriction on the relative rotation of the rotating wheel 520 with respect to the fixed wheel 510.

[0041] Meanwhile, in order for the stoppers 550, 560, and 570 to stably restrict and release the movement, their operating range must be limited. The operating range of the stoppers is limited within a certain range by the combination of the pressing areas of the fixed ring 510 and the rotating ring 520 and the position setting means.

[0042] 4 to 8, an embodiment of the rotation control means 500 according to the present invention is described. Fixed rings 510 of the rotation control means 500 are formed on both sides of the upper body part 100, a rotating ring 520 that moves with the armrest 200 is inserted in the center of the fixed ring 510, at least one stopper 550 is interposed between the fixed ring 510 and the rotating ring 520, and at least one groove 530 in which the stopper 550 is located is formed. The groove 530 may be formed in the rotating ring 520, or as shown in FIG. 6, may be formed in the fixed ring 510. The groove 530 according to the embodiment is formed with an inclined surface 531 on which an inclined pressing area is located so that the gap between the pressing areas formed in the fixed ring 510 and the rotating ring 520 narrows to perform a constriction action or widens to release the gap depending on the direction of relative rotation between the fixed ring 510 and the rotating ring 520. Meanwhile, in addition to the inclined surface 531, the groove 530 is formed with a side wall 532 as a positioning means for limiting the operating range of the stopper 550 to a certain extent, and the operating range of the stopper 550 is limited to a certain range by the combination of the side wall, the fixed wheel 510 and the pressing area of ​​the rotating wheel 520.

[0043] Therefore, according to the embodiment, when the armrest 200 is rotated in the rotation restriction direction, the rotating wheel 520 is constrained relative to the fixed wheel 510 by the constriction action of the fixed wheel 510, the rotating wheel 520 and the stopper 550, thereby restricting the rotation. The greater the external force that rotates the armrest 200, the greater the force that constrains the armrest 200. Therefore, the rotation of the armrest 200 can be effectively controlled only by the external force acting on the armrest 200, without using a powerful compression spring.

[0044] Meanwhile, the stopper 550 of the rotation control means 500 according to the embodiment is not limited to this shape. That is, it may be configured as a ball that makes point contact as shown in Figures 4 to 6, or as a cylindrical shape that makes line contact (not shown), or as a polyhedron that makes surface contact as shown in Figures 7 and 8.

[0045] In addition, it is preferable that the rotation control means 500 further includes an elastic body 580 or a magnetic body 585 as a contact maintaining means for maintaining the stopper 550 in contact with the fixed ring 510 and the rotating ring 520 in the direction of the restriction. Specifically, when the rotation control means 500 restricts rotation, if the stopper 550 is spaced apart from the fixed ring 510 and the rotating ring 520 in the restricting direction without contacting them, an immediate constriction action is not performed. Therefore, the rotating ring 520 may rotate partially before the constriction action is performed, or in some cases, the constriction action may not be performed effectively. To minimize this, the elastic body 580 is provided as a contact maintaining means to maintain the stopper 550 in contact with the fixed ring 510 and the rotating ring 520. Here, the elastic body 580 may be formed in a coil shape as shown in FIGS. 5 and 6, or in a plate shape as shown in FIG. 7. In addition, the elastic body 580 may be formed on the fixed ring 510 or the rotating ring 520, or on the stopper 550, taking into consideration the position where the groove 530 is formed, and may also be formed integrally with the fixed ring 510, the rotating ring 520, or the stopper 550 as needed.

[0046] Referring to FIG. 8, an example in which a magnetic body 585 is used as the contact maintaining means will be described. One of the pair of magnetic bodies 585 constituting the contact maintaining means is formed on the rotating wheel 520 or the fixed wheel 510, and the other is formed on the stopper 550, so that the stopper 550 can be maintained in contact with the fixed wheel 510 and the rotating wheel 520 by using the attractive or repulsive force generated between the two magnetic bodies 585.

[0047] Meanwhile, the rotation restriction action of the armrest 200 is not performed by the action of the elastic body 580 or the magnetic body 585, but is restricted by the constriction action using an external force that rotates the armrest 200. Therefore, the elastic force of the elastic body 580 and the magnetic force of the magnetic body 585 are sufficient as long as they are sufficient to maintain the stopper 550 in contact with the fixed wheel 510 and the rotating wheel 520.

[0048] 7, in order to prevent slippage of the stopper 550 and to enhance the constriction effect, a concave-convex portion 555 may be formed in at least one of the fixed ring 510, the rotating ring 520, and the pressing area of ​​the stopper 550. Here, the concave-convex portion 555 is a protrusion formed on one side of the pressing area or a combination of a protrusion and a groove formed on both sides of the contact surface, and its shape is not limited to a sawtooth shape, a triangle, a semicircle, a diagonal line, a dot shape, etc.

[0049] Another embodiment of the rotation control means will be described with reference to FIGS. 9 and 10. The stopper 560 provided in the rotation control means 500 is an irregular roller that makes line contact with the fixed wheel 510 and the rotating wheel 520. An inclined surface 565 is formed on one or both sides of the outer periphery of the stopper 560 so that the distance between the corresponding pressing areas on both sides gradually changes. When the armrest 200 is rotated in the rotation restriction direction, the stopper 560 rotates in a direction that increases the distance between the pressing areas on both sides, causing both pressing areas of the stopper 560 to press and come into contact with the pressing areas of the fixed wheel 510 and the rotating wheel 520, thereby performing a constriction action and restricting the rotation of the armrest 200. When the armrest 200 is rotated in the restriction release direction, the stopper 560 rotates in a direction that decreases the distance between the pressing areas on both sides, thereby releasing the constriction and allowing the armrest 200 to rotate freely.

[0050] Meanwhile, a position setting means must be provided to allow the stopper 560 to operate within a certain range. As shown in Fig. 9, a separate guide ring 590 into which at least one stopper 560 is inserted is used, or as shown in Fig. 10, a groove 530 is formed in the fixed ring 510 or the rotating ring 520 and its side wall 532 is used. Therefore, the operating range of the stopper 560 is limited within a certain range by the combination of the position setting means and the pressing areas of the fixed ring 510 and the rotating ring 520.

[0051] In addition, it is preferable to form an elastic body 580 as a means for maintaining contact of the stopper 560 with the fixed ring 510 and the rotating ring 520. Therefore, as shown in Fig. 10, the elastic body 580 can be installed on the stopper 560, and can be selectively formed on any of the fixed ring 510, the rotating ring 520, and the guide ring 590.

[0052] Meanwhile, by forming a concave-convex portion on at least one of the fixed ring 510, the rotating ring 520 and the pressing area of ​​the stopper 560, slippage of the stopper 560 can be prevented and the constriction effect can be made stronger.

[0053] 11, a stopper 570 provided in the rotation control means 500 is composed of a first member 571 that comes into surface contact with the fixed wheel 510 or the rotating wheel 520 and a second member 572 that guides the constriction of the first member 571 according to the rotation direction of the rotating wheel 520. Here, a position setting means must be provided to allow the stopper 570 to operate within a certain range, and therefore a groove 530 can be formed and its side wall 532 can be used.

[0054] Preferably, the first member 571 of the stopper 570 is a polyhedron that is in surface contact with the inner peripheral surface of the fixed ring 510, and the second member 572 is formed of a link member that connects the rotating ring 520 and the first member 571. When the armrest 200 is rotated in the rotation restriction direction, as the second member 572 of the stopper 570 rotates in a direction that presses the first member 571 toward the fixed ring 510, pressing areas on both sides of the first member 571 and the second member 572 press against pressing areas of the fixed ring 510 and the rotating ring 520, thereby performing a constriction action and restricting the rotation of the armrest 200. When the armrest 200 is rotated in the restriction release direction, the second member 572 of the stopper 570 rotates in the opposite direction to release the constriction action, thereby allowing the armrest 200 to rotate freely. An elastic body 580 may be provided as a contact maintaining means for maintaining the stopper 570 in contact with the fixed ring 510 and the rotating ring 520 in the rotation restricting direction. In addition, by forming an uneven portion on at least one of the pressing areas of the fixed ring 510, the rotating ring 520, and the stopper 570, slippage of the stopper 570 can be prevented and the constriction effect can be made stronger.

[0055] Meanwhile, in each embodiment of the rotation control means 500 according to the present invention, it is preferable to provide a cover 540 for preventing the rotation wheel 520 and the stoppers 550, 560, 570 from coming off the fixed wheel 510.

[0056] As described above, various embodiments of the rotation control means 500 are possible depending on the constriction method, and in each embodiment, the fixed ring 510, the rotating ring 520, and the stoppers 550, 560, and 570 may have various shapes. The fixed ring 510, the rotating ring 520, and the stoppers 550, 560, and 570 may have any shape as long as the relative distance between the pressing areas of the fixed ring 510 and the rotating ring 520 and the pressing areas of the stoppers 550, 560, and 570 changes when the rotating ring 520 rotates relative to the fixed ring 510, thereby causing a constriction or releasing the constriction. The contact method between the stoppers 550, 560, and 570 and the fixed ring 510 and the rotating ring 520 may be a point contact method, a line contact method, an area contact method, or a combination of these contact methods. The present invention is not limited to the shapes of the fixed ring 510, the rotating ring 520, and the stoppers 550, 560, and 570.

[0057] In each of the above-described embodiments of the present invention, the rotation control means 500 and the armrests 200 are selectively linked to each other, and the armrests 200 are allowed to rotate freely without being linked to the rotation control means 500, so that after the baby has been bathed, the armrests 200 on both sides can be freely spread outward.

[0058] Specifically, the pair of armrests 200 hingedly connected to the upper body part 100 are provided with a rotation shaft 600 therein, as shown in Figures 12 and 13. A number of engagement protrusions 630 are partially formed on the outer circumferential surface of the rotation shaft 600, and an engagement groove 525 into which the engagement protrusions 630 are engaged is formed at the rotation center of the rotating wheel 520 of the rotation control means 500. When the engagement protrusions 630 engage with the engagement groove 525, the armrests 200 are interlocked with the rotation control means 500, and when the engagement protrusions 630 disengage from the engagement groove 525, the armrests 200 spin freely without being interlocked with the rotation control means 500, and the rotation restriction on the armrests 200 is released, so that the armrests 200 can be freely spread outward.

[0059] In order for the engaging protrusion 630 to be selectively coupled to the engaging groove 525, the rotating shaft 600 must be able to move its position vertically in the axial direction and maintain its coupled state with the armrest 200, and therefore, is provided with at least one slider having a combination of a protrusion and a groove. Preferably, as shown in Fig. 12, an upper groove 610 is formed on the upper side of the rotating shaft 600, which is slidably coupled with an upper protrusion 210 formed on the inner upper side of the armrest 200, and a lower protrusion 620 is formed on the lower side of the rotating shaft 600, which is slidably coupled with a lower groove 220 formed on the inner lower side of the armrest 200. Meanwhile, the combinations of protrusions and grooves as sliders formed on the rotating shaft 600 and the armrest 200, respectively, may be formed with their positions interchangeable.

[0060] Preferably, a spring 650 is disposed above the rotating shaft 600 so that the engaging protrusion 630 normally remains engaged with the engaging groove 525 of the rotating wheel 520, and the engaging protrusion 630 disengages from the engaging groove 525 of the rotating wheel 520 when the rotating shaft 600 is pushed upward. The upper end of the spring 650 is supported on the upper interior side of the armrest 200, and the lower end of the spring 650 is supported by a support protrusion 640 formed on the outer circumferential surface of the rotating shaft 600. The elastic force of the spring 650 does not affect the rotation limiting action of the rotation control means 500, but acts only when the rotating shaft 600 is pushed upward to release the rotation limit on the armrest 200. Therefore, the strength of the spring 650 can be optimally selected according to the user's convenience. Meanwhile, the lower end of the rotating shaft 600 disposed inside the armrest 200 penetrates the bottom surface of the armrest 200, thereby serving as a button for pushing up the rotating shaft 600.

[0061] The baby bathing aid according to the present invention includes a skin protection means for preventing the baby's skin from being pinched in the gap between the upper body part 100 and the armrest 200, or for preventing the baby's skin from being pressed against the gap even if the baby's skin is positioned in the gap, thereby preventing injury. The skin protection means will be described below with reference to Figures 14 to 17.

[0062] Specifically, when the armrest of the bathing aid is rotated inward, the mating parts of the upper body part and the armrest interact like pressure rollers, which draw and press objects that come into contact with them into the mating parts due to friction, so if the armrest is rotated inward with the baby's skin in close contact with the mating parts, the baby's skin may be pulled in or pressed into the gap due to the movement of the mating parts, causing an injury. The space part 230 for preventing skin pinching of the skin protection means is formed so that the shape of the mating parts of the upper body part 100 and the armrest 200 does not have a structure that interacts like a pressure roller, and may be formed in any one or all of the mating parts of the upper body part 100 and the armrest 200. The space 230 for preventing skin pinching according to a preferred embodiment of the present invention is a space having a predetermined shape formed from the outside to the inside at least a part of the mating part of the armrest 200, i.e., the part where the armrest 200 may pull in or press the skin due to frictional force as it rotates inward. As shown in FIGS. 3 and 14, the space 230 for preventing skin pinching, which is a vertically concave space, is formed at the mating part of the armrest 200, and is different from a shape that causes interaction like a pressure roller. This prevents the skin that is in close contact with the mating part of the upper body part 100 and the armrest 200 from being pulled into the gap at the mating part when the armrest 200 is narrowed inward. Even if a part of the skin is pulled in, the gap widens. Therefore, unlike conventional cases where the skin is pinched and pressed into a narrow gap, the present invention does not cause pressure and does not cause injury to the baby.

[0063] As described above, the space 230 for preventing pinching of the skin may have any shape as long as the shape of the mating part of the upper body part 100 and the armrest 200 can be free from the structure where interaction occurs such as the pressure roller, and may be formed in various shapes such as a concave shape or a flat shape, and the present invention is not limited to the shape of the space 230 for preventing pinching of the skin.

[0064] 15 to 17, the structure of the blocking member 240 as the skin protection means will be described. The blocking member 240 blocks a part or all of the gap formed between the upper body part 100 and the armrest 200 to prevent the baby's skin from entering the gap, and is made of a soft material such as silicone to block a part or all of the gap while preventing discomfort when it comes into contact with the baby's skin. Specifically, the blocking member 240 may be configured in various forms such as a pad type, a protrusion type, a covering type, etc., and may be formed in either the upper body part 100 or the armrest 200, or may be formed together with the space portion 230 for preventing skin pinching.

[0065] 15, the pad-type blocking member 240 has a flat surface and is configured to block a part or all of the entrance of the gap formed between the upper body part 100 and the armrest 200. For example, fastening holes 120 are formed on both sides of the upper body part 100, and the blocking member 240 is detachably coupled by engaging members 245 that engage with the fastening holes 120, thereby allowing the blocking member 240 to be easily separated for cleaning or replacement. Meanwhile, the engaging members 245 are formed in a shape that is bent toward the fastening holes 120 of the upper body part 100. The engaging members 245 of the blocking member 240 can be designed in various shapes and methods.

[0066] As shown in FIG. 16, the protrusion-type blocking member 240 is formed to protrude considerably from the joining portion of the upper body portion 100 and the armrest 200, thereby preventing the baby's skin from approaching the gap when the armrest 200 is narrowed inward and blocking the skin from entering the gap.

[0067] In addition, as shown in Figure 17, the covered blocking member 240 completely covers the entrance of the gap, thereby preventing the baby's skin from being pulled into the gap, and the covered blocking member can also be formed to extend to the top end of the upper body part 100 or the top end of the armrest 200.

[0068] The blocking member may be formed in various shapes to block a part or all of the gap, but the present invention is not limited to the shape of the blocking member.

[0069] In addition, as another safety measure, slip-off prevention portions 250 are formed at the ends of the armrests 200. Specifically, even if the outward rotation of both armrests 200 is restricted, if the weight of the infant is excessively concentrated on the ends of the armrests 200, the infant's flexible upper body may slip through the space between the ends of the armrests 200, or if an infant with underdeveloped lower body muscles sits down, the infant's neck may slip through the space between the ends of the armrests 200 and be injured. In the present invention, as shown in FIGS. 3 and 14, the slip-off prevention portions 250 are formed to extend gently upward on the same line facing each other so that the ends of both armrests 200 can stably support the infant's back or chest, thereby preventing the infant from slipping through the gap between the armrests 200. Furthermore, by setting the distance L between the slip-off prevention portions 250 to 3 cm or less when the both armrests 200 are fully closed, the infant's neck is supported even when the infant sits down, preventing injury.

[0070] The recommended age for using the baby bath aid of the present invention is between 5 and 24 months of age. Therefore, 20 babies aged 5 to 6 months, who have the thinnest necks among babies in this age group and are at greatest risk of falling, were investigated to see whether the baby's neck could pass through depending on the spacing between the anti-slip parts 250. As a result, as shown in Table 1, all babies could pass through up to 7 cm, but some babies could not pass through at spacings of 6 cm, most babies could not pass through at spacings of 4 cm, but some could pass through, and at spacings of 3 cm, all babies could not pass through. Therefore, there is a significant qualitative effect when the spacing L between the anti-slip parts 250 on both sides is 3 cm or less.

[0071] [Table 1]

[0072] The baby bathing aid according to the present invention is provided with a number of drain holes 270 and partitions 281, 282 in the armrest 200 as a means for preventing hygienic problems, such as mold growth due to water entering the armrest 200. Specifically, as shown in FIGS. 4 and 12, the armrest 200 is hinged to the upper body 100 for rotation, and therefore an operating hole H into which the housing 150 of the upper body 100 is inserted is inevitably formed. However, water that enters the armrest 200 through the operating hole H not only does not drain naturally to the outside, but also causes inconvenience, such as the need to tilt the bathing aid to drain the water, and in fact, this process may cause the water to penetrate deeper. If water remains inside the handle 200, not only will it cause splashing sounds inside the bathing aid, but it will also cause hygienic problems, such as mold growth inside the armrest 200. Therefore, the present invention prevents water from remaining inside the armrest 200 by forming a number of drain holes 270 in the bottom surface of the armrest 200. That is, as shown in Fig. 12, the interior of the armrest 200 is divided into a number of spaces by reinforcing ribs, and a drain hole 270 is formed on the bottom of the lowest position of each divided space, so that water that has flowed into the interior of the armrest 200 can be naturally discharged. Also, in order to minimize the area into which water can flow into the interior of the armrest 200, as shown in Fig. 12, partitions 281 and 282 that also serve as reinforcing ribs are formed on the upper and lower sides of the interior of the armrest 200, and the ends of the partitions 281 and 282 are in contact with and overlap each other, so that water that has flowed into the operating hole H of the armrest 200 is fundamentally prevented from flowing into other divided spaces, thereby minimizing the area into which water can flow.

[0073] Furthermore, when assembling the armrest 200, the joints can be joined using ultrasonic waves, heat fusion, adhesives, resins, waterproof finishing agents, etc., thereby fundamentally preventing water from entering the inside of the armrest 200.

[0074] 3, the lower body part 300 is formed below the upper body part 100 and includes a step 310, which is a space for the baby to stand up by stepping on it, and a border part 320 that protrudes upward from the edge of the step 310. Even if the bathing aid tilts, the baby's weight acts as a load on the step 310 to maintain the center of gravity, so the bathing aid does not tip over but returns to an upright position. The border part 320 prevents the baby from slipping off the step 310 and also restricts the baby's position by maintaining the center of gravity of the lower body part 300 continuously according to the baby's weight.

[0075] As shown in FIGS. 3 and 18, the lower body part 300 has a discharge port 330 formed in front of a step 310 that contacts the boundary part 320, and a discharge passage 340 connected to the discharge port 330 is formed in the front of the bottom surface of the lower body part 300, so that foreign matter such as cleansing water and feces can be immediately discharged without accumulating on the step 310. Specifically, since the boundary portion 320 formed on the lower body portion 300 is open to the rear of the bathing aid, the washing water and the like can be easily discharged behind the step stool 310. However, since the bottom of a bathroom or bathtub is generally inclined, the washing water and the like can accumulate in front of the step stool 310 depending on the direction in which the bathing aid is used. In particular, when washing away feces after defecation, if feces accumulate in front of the step stool 310 on which the baby steps, the feces will get on the baby's feet again, which is unhygienic. Therefore, the washing water and the like are designed to be quickly discharged through the discharge port 330 and discharge passage 340.

[0076] Here, the outlet 330 is formed in a tunnel shape at the boundary part 320, and is preferably formed wide on both sides to quickly discharge the cleaning water, etc., and the outlet passage 340 formed on the bottom of the lower body part 300 ensures sufficient space so that foreign matter such as feces discharged through the outlet 330 can be smoothly discharged and does not stick to the bottom of the bathroom or bathtub or the bottom of the lower body part 300 again, and also plays a role in guiding the flow of the cleaning water, etc. to one side.

[0077] As described above, the outlet 330 and the outlet passage 340 may be formed in any shape as long as they are formed in the boundary portion 320, such as on the side of the platform 310, and may be formed in various shapes such as multiple narrow tunnels, and the present invention is not limited to the shape of the outlet 330 and the outlet passage 340.

[0078] In addition, the bottom surface of the lower body part 300 comes into contact with the bottom of the bathroom or bathtub at multiple points to prevent the bathing aid from tipping over or slipping. Furthermore, by attaching friction members 370 made of a material with a high friction coefficient to the multiple contact points, the friction force can be increased, thereby preventing the bathing aid from slipping.

[0079] An anti-slip pad 350 may be further provided on the top of the step stool 310 of the lower body part 300 so as to be detachable by an attachment / detachment means to prevent the baby from slipping and falling and getting injured. The anti-slip pad 350 is preferably made of a flexible resin that is soft yet has excellent anti-slip properties, such as silicone, rubber, thermoplastic elastomer (TPE), or polyvinyl chloride (PVC), and is formed in a shape that corresponds to the shape of the step stool 310. As shown in FIG. 19 , the anti-slip pad 350 has protrusions 351 on its upper surface to prevent the baby's feet from slipping, and recesses 352 on its bottom surface to improve the contact force between the step stool 310 and the anti-slip pad 350 and provide a cushioning feeling when the baby steps on the anti-slip pad 350. The anti-slip pad 350 may also have a number of through holes 353 formed therein to allow water to drain quickly without accumulating.

[0080] Meanwhile, the attachment / detachment means is composed of an adsorption plate 354 formed on the bottom surface of the anti-slip pad 350, thereby increasing the contact force with the step stool 310 and enabling more secure attachment / detachment. In addition, the attachment / detachment means includes a fixing protrusion 355 formed on the bottom surface of the anti-slip pad 350 and a fixing groove 315 formed on the step stool 310 and corresponding to the fixing protrusion 355, thereby enabling the anti-slip pad 350 to be easily and securely attached / detached to / from the step stool 310 without using adhesive such as glue. In addition, the anti-slip pad 350 can be easily cleaned, allowing it to be kept clean and free from water stains and mold.

[0081] The height adjusting unit 400 of the present invention will now be described. The height adjusting unit 400 is formed between the upper body unit 100 and the lower body unit 300 below it, and can adjust the height of the upper body unit 100 relative to the lower body unit 300. More specifically, the height adjusting unit 400 includes an upper support unit 410 formed below the upper body unit 100, a lower support unit 430 formed on one side of the lower body unit 300 and into which the upper support unit 410 is inserted, and a known fixing button 450 provided in the lower support unit 430 and fixing the position of the upper support unit 410. The height adjusting unit 400 of the present invention is not limited by the operating methods of the upper support unit 410, the lower support unit 430, and the fixing button 450.

[0082]

[0033] The structure of the play means 700 that attracts the interest of infants in the present invention will now be described. Even for infants who are not accustomed to using an infant bathing aid, or even for infants who are accustomed to using it, the longer the bath time, the more uncomfortable the infant becomes, and the more unstable the posture becomes, requiring special care during bathing. The present invention makes the play means 700 detachable from the upper body portion 100 or the height-adjustable portion 400, allowing the infant or guardian to efficiently switch between different play means that are most preferred by the infant or guardian. Consumers can also purchase bathing aids without play means, reducing the cost of purchasing bathing aids. This allows selection of play means that stimulate the visual and tactile senses, which are generally recommended for infants of a certain age who use bathing aids. As infants use the bathing aid, they can see and touch the play means with their eyes and hands, which not only attracts the infant's interest but also promotes brain development through visual and tactile stimulation and small muscle development through touching.

[0083] Specifically, the play means 700 can be attached and detached to any part of the baby bathing aid, preferably to any part that the baby can see or reach so that the baby can play while looking and touching, and can stimulate the baby's visual and tactile senses. Here, the play means 700 is not limited to the form of a spinner, rattle, or toy.

[0084] In addition, in order to easily adjust the position of the play means 700 so that it is within the baby's line of sight or reach, or to install multiple play means simultaneously, a separate support means 750 as shown in Figs. 3 and 20 can be interposed between the play means 700 and the baby bathing auxiliary device, such as the upper body part 100, the height adjustment part 400, or the armrest 200. The support means 750 is detachably installed on the baby bathing auxiliary device, and may be formed integrally with or detachably formed with the play means 700. In one embodiment, as shown in Fig. 20, an insertion hole 170 is formed in the bottom surface of the upper body part 100, and the lower end of the support means 750 is inserted and fixed into this hole, and the play means 700 can be attached to the upper end of the support means 750.

[0085] The support means 750 may also be configured in various shapes, and may be formed into an I-shape or an inverted U-shape in addition to the J-shape shown in the drawings. In addition to such rod-shaped support means, a table-shaped support means may also be formed. As for the attachment method, the support means may be designed and modified into various shapes and methods other than the form in which the support means is inserted into the upper body part 100, and the present invention is not limited to the shape of the support means 750.

[0086] Although not shown, the play means 700 is formed in a manner that it is inserted into or attached to the rod-shaped support means, and when the play means 700 is separated from the support means, it can be used as a toy in daily life.

[0087] On the other hand, since the bathing aid according to the present invention has a relatively large volume compared to the small bathroom area, when it is stored on the floor of the bathroom or bathtub, it can cause inconvenience when the bathroom is used for other purposes due to the space it occupies. In addition, moisture can remain on the bottom of the lower body, which comes into contact with the floor of the bathroom, and mold can grow. Therefore, as shown in Figure 18, it is preferable to form at least one or more hanging means 810, 820, 830 such as grooves or hangers on the upper body 100 and lower body 300 of the bathing aid, and install a hanging device such as an S-shaped hanger on an existing bathroom structure such as a towel rack or towel shelf, or attach a separate hanging device to the bathroom wall, and store the bathing aid on it. Specifically, the bathing aid can be stored upright by using the hanging means 810, 820 formed on the rear or side of the upper body part 100, or the bathing aid can be stored lying down against a wall or hanging upside down by using the hanging means 830 formed on the lower body part 300. The hanging means can be in any form that allows hanging, such as a groove or a hook, and the present invention is not limited to the form of the hanging means.

[0088] In this way, the bathing aid can be easily stored in the bathroom using a hanging means, etc., allowing for efficient use of bathroom space, and it dries easily and does not get moldy, allowing for hygienic use. Furthermore, when the bathing aid is brought to a living room or other room other than the bathroom and used for other purposes, such as supporting an infant when changing diapers or clothes, the present invention allows moisture on the bottom of the lower body part 300 to dry quickly, eliminating the inconvenience and hygienic problems of water dripping into the living room or room when moving it.
