Abstract
Description
Technical Field
[0001] This invention relates to the field of posture correction technology, and more particularly to a posture training device for children. Background Technology
[0002] Sitting is a posture where the buttocks are on the ground and the body is perpendicular to the ground, starting from the pelvis and moving upwards. The ultimate goal of achieving sitting is to maintain a stable sitting position with the spine vertically extended without upper limb support. Normal children can sit by 7-8 months. Not being able to sit means that sitting development has stalled before the stage of assisted sitting or that abnormal postures such as kneeling or leaning backwards are observed. Independent sitting is the first milestone in gross motor development, and sitting is an intermediate posture in the development towards standing. If a child cannot sit, they cannot stand. Therefore, sitting training and posture correction training are crucial in a child's development.
[0003] To address the issue of children's inability to sit properly, sitting training and posture correction training should begin in early childhood. During the training process, appropriate training aids should be used, such as cylindrical aids for posture correction training. Traditional training aids have poor adaptability and adjustability, cannot be adjusted for different types of children, and are inconvenient for operators during operation, making it difficult to effectively train and control the child's sitting posture.
[0004] Therefore, there is an urgent need for a child sitting posture training device to solve the above problems. Summary of the Invention

Furthermore, the terms "first" and "second" are merely used for descriptive distinction and have no special meaning.
[0039] like Figures 1 to 6As shown, this embodiment provides a child sitting posture training device, which includes a correction component. The correction component includes a first pad 1 and a second pad 2. The first pad 1 has a first top surface 11 and a first bottom surface 12 that are disposed opposite to each other. The second pad 2 has a second top surface 21 and a second bottom surface 22 that are disposed opposite to each other, and a plurality of side surfaces 23 disposed between the second top surface 21 and the second bottom surface 22. At least two adjacent side surfaces 23 are disposed at a preset angle, for example, at 90°. Of course, the angle between the two side surfaces 23 can also be other angles, such as acute angles or obtuse angles. The second bottom surface 22 and the first bottom surface 12 are detachably connected. The size of the second bottom surface 22 is smaller than that of the first bottom surface 12. The first pad 1 has a support position and a table position relative to the second pad 2. When the first pad 1 is in the support position, the child can sit on the second top surface 21 and step on the first bottom surface 12. Both legs can rest against the two sides 23 set at a preset angle. When the first pad 1 is in the table position, the child's legs can rest against the two sides 23 set at a preset angle in the sitting position. The first top surface 11 is used to place items. By placing the first pad 1 under the second pad 2, a step is formed between the two pads, allowing the child to sit on the second top surface 21 with their feet on the first bottom surface 12. Both legs can rest against the two angled sides 23, ensuring the child's legs are spread at the required angle, thus training the child's sitting posture. This operation is simple, and the pre-set angled sides 23 act as guides, avoiding the need for operators to rely on experience to control the child's leg angle and position during assistance, improving training effectiveness and saving manpower. Simultaneously, by placing the first pad 1 on top of the second pad 2, the child's legs can be fully extended and pressed against the two angled sides 23 when seated, providing another sitting posture training. During training, items to attract the child's attention, such as toys, can be placed on the first top surface 11 to reduce the difficulty of training and ensure its smooth progress.
[0040] like Figure 1 and Figure 6 As shown, to improve the flexibility of the child's sitting posture training device, the correction component also includes a middle pad 3, which is detachably connected between the first bottom surface 12 and the second bottom surface 22. The middle pad 3 may have the same or different shape as the second pad 2. The height of the correction component can be adjusted according to the child's height and body shape to suit children in different situations. Furthermore, by adding the middle pad 3, the child can stand and lean against the correction component, while also holding onto the first top surface 11, thereby achieving corrective training for the child's standing posture and further improving the flexibility and practicality of the child's sitting posture training device.
[0041] Optionally, multiple intermediate pads 3 can be provided to facilitate operators in placing an appropriate number of intermediate pads 3 between the first pad 1 and the second pad 2 according to usage requirements. Preferably, the shape and size of the intermediate pads 3 are the same as those of the second pad 2 to ensure consistency, improve training effectiveness, and facilitate assembly.
[0042] For example, the first pad 1, the second pad 2, and the middle pad 3 are all rectangular, with the rectangular corners serving as training angles. That is, each corner can be used as a training angle, eliminating the need to specifically align with the two sides 23 set at a preset angle during training. When the second bottom surface 22 and the first bottom surface 12 are connected, each rectangular corner of the second pad 2 faces one side of the first pad 1. When the child sits on the second top surface 21 with their legs apart, the first bottom surface 12 provides sufficient space for the child's feet to rest on. Of course, in other embodiments, the first pad 1, the second pad 2, and the middle pad 3 can also be other shapes, such as pentagons, hexagons, or irregular shapes, depending on the actual needs.
[0043] Specifically, such as Figure 4 and Figure 5 As shown, a first connector 14 is provided on the first bottom surface 12, and a second connector 24 is provided on the second bottom surface 22. The first connector 14 and the second connector 24 are detachably connected. The first pad 1 and the second pad 2 are detachably connected through the first connector 14 and the second connector 24. For example, one of the first connector 14 and the second connector 24 is a hook-and-loop fastener, and the other is a loop fastener, resulting in a simple structure and convenient operation. More specifically, a third connector 31 is provided on each of the opposite sides of the middle pad 3. The third connector 31 is detachably connected to both the first connector 14 and the second connector 24. For example, the third connector 31 is either a hook-and-loop fastener or a loop fastener. This facilitates assembly and disassembly, and the surface of the middle pad 3 is relatively flat when not in use, allowing it to be used for other purposes, such as a seat cushion, thus improving practicality and applicability. Of course, in other embodiments, the first connector 14, the second connector 24, and the third connector 31 can also be other structures, such as hooks and hanging ropes, depending on the specific circumstances.
[0044] Preferably, a plurality of limiting blocks 6 are provided around the first bottom surface 12, and the side 23 of the second pad 2 can abut against the plurality of limiting blocks 6. For example, the plurality of limiting blocks 6 are arranged around the outer periphery of the first connecting member 14. When assembling the first pad 1 and the second pad 2, the second pad 2 can be placed in the space surrounded by the plurality of limiting blocks 6. The limiting blocks 6 can restrict the lateral sliding of the second pad 2 relative to the first pad 1, thereby improving the stability and reliability of the child sitting posture training device. More preferably, a plurality of limiting blocks 6 are also provided around the second bottom surface 22, and the plurality of limiting blocks 6 are arranged around the outer periphery of the second connecting member 24. When the middle pad 3 is assembled with the first pad 1 and the second pad 2, both ends are limited by the limiting blocks 6 on the first bottom surface 12 and the limiting blocks 6 on the second bottom surface 22, respectively, to prevent the middle pad 3 from sliding laterally, thereby improving the stability and reliability of the child sitting posture training device.
[0045] Furthermore, the first pad 1 includes a first packaging layer and a first filler. The first packaging layer is provided with an openable and closable first filling port, through which the first filler can be filled into or removed from the first filling port. This facilitates the disassembly and assembly of the first pad 1, thereby facilitating the replacement of the first packaging layer or the first filler, ensuring the quality and training effect of the child sitting posture training device, saving costs, and also facilitating the cleaning of the first packaging layer, maintaining the cleanliness of the child sitting posture training device, and improving hygiene.
[0046] Specifically, a zipper 15 is provided at the openable / closeable opening on the first packaging layer. The first packaging layer can be opened or closed by means of the zipper 15. The structure is simple, the cost is low, and the operation is convenient. Of course, in other embodiments, the openable / closeable opening on the first packaging layer can also be provided with other structures, such as a button, etc., and the first packaging layer can be opened and closed by means of the button engaging the buttonhole.
[0047] For example, the first packaging layer is made of artificial leather, which facilitates daily disinfection and cleaning without the need for removal and washing, thus improving hygiene and ensuring safety during use. Of course, in other embodiments, the first packaging layer may also be made of other materials, such as cloth, depending on the actual needs.
[0048] For example, the first filling material includes a sponge. The first filling material can be a single sponge block or multiple sponge pads. The sponge has good flexibility, improving comfort and facilitating filling and removal, while also being lightweight for easy movement. The multi-layered sponge configuration allows for adjustment of the thickness of the first pad 1 within a certain range as needed, providing good flexibility. Of course, in other embodiments, the first filling material can also be other materials, such as wood, depending on actual requirements.
[0049] In this embodiment, the structure and material of the second pad 2 and the intermediate pad 3 can be the same as those of the first pad 1. For example, the second pad 2 includes a second packaging layer and a second filler. The second packaging layer is provided with an openable and closable second filling port, through which the second filler can be filled into the second packaging layer or extracted from the second filling port. The intermediate pad 3 is the same as above, and will not be described in detail here.
[0050] Refer again Figure 1 To further reduce operator workload, the child sitting posture training device also includes a backrest 4, which is positioned on one side of the correction component, allowing the child to lean against it. During correction training, the child stands or sits between the backrest 4 and the correction component. After adjusting to the training posture, the backrest 4 prevents the child from leaning backward or falling, thus fixing the child's position and posture, improving the training effect, and freeing up the operator's hands. The operator does not need to constantly support the child, making the child sitting posture training device more practical and applicable.
[0051] Specifically, the backrest 4 includes a first backrest panel 41 and a second backrest panel 42 arranged at an angle. The side of the first backrest panel 41 and the second backrest panel 42 with an angle no greater than a flat angle forms a support surface, allowing the child to lean against it. The angle between the first backrest panel 41 and the second backrest panel 42 improves the stability of the backrest 4 and reduces the child's comfort when leaning against it, preventing the child from relying on the backrest 4 and affecting the training effect. Furthermore, the angled first backrest panel 41 and the second backrest panel 42 also protect the child's sides 23, preventing the child from tipping over. For example, the angle between the first backrest panel 41 and the second backrest panel 42 is 90°. Of course, in other embodiments, the angle between the first backrest panel 41 and the second backrest panel 42 can also be an acute angle or an obtuse angle, depending on the actual needs.
[0052] Optionally, the backrest 4 also includes a base, which is vertically connected to the first backrest plate 41 and the second backrest plate 42 and extends toward the side away from the backrest surface, thereby improving the stability of the backrest 4, preventing the child from pushing the backrest 4 over when leaning against it, and improving the reliability of the child sitting posture training device.
[0053] In another embodiment, the backrest 4 may also be in other shapes, such as the side of the backrest 4 near the correction component being arc-shaped or wavy. The arc shape can improve comfort, and the wavy shape can improve the stability of the backrest 4. The shape of the backrest 4 can be set according to the requirements.
[0054] Furthermore, the child sitting posture training device also includes a fixing mat 5 with an anti-slip layer. The corrective components can be placed on the anti-slip side of the fixing mat 5. The child can stand or sit on the fixing mat 5, which provides a training space. At the same time, the anti-slip layer improves the stability of the corrective components, preventing them from slipping during training and affecting operation and training effectiveness.
[0055] Preferably, the first top surface 11 and the second top surface 21 are provided with a textured surface of Velcro, and the anti-slip layer is the hook surface of Velcro. The orthotics component is fixed by fixing the first top surface 11 to the anti-slip layer or the second top surface 21 to the anti-slip layer. The textured surface of the first top surface 11 and the second top surface 21 will not cause discomfort to the child, thus improving comfort. Of course, in other embodiments, the anti-slip layer can also be other structures, such as a rubber anti-slip surface. The first pad 1 or the second pad 2 placed on the rubber anti-slip surface has a large friction force, avoiding slippage and improving reliability.
[0056] Preferably, the backrest 4 is also provided with an anti-slip structure on the fixed blanket 5, which can be a Velcro or rubber anti-slip surface, etc., depending on the actual needs.
[0057] More preferably, the back of the fixing blanket 5, that is, the side facing away from the corrective component, is also provided with an anti-slip layer to improve the stability of the fixing blanket 5 and prevent the fixing blanket 5 from sliding relative to the ground or tabletop.
[0058] During corrective training, when the child is seated or standing with their legs and feet in the correct positions, a foot restraint (not shown in the figure) is provided on the first pad 1 to prevent the child from moving on their own and causing training failure. When the child sits on the second top surface 21 and places their feet on the first bottom surface 12, the foot restraint can fix the child's feet. A leg restraint (not shown in the figure) is provided on the second pad 2 to fix the child's legs. The foot and leg restraints can fix the child's feet and legs during training, preventing the child from moving around and affecting the training effect, and eliminating the need for the operator to constantly pay attention to and adjust the position of the legs and feet.
[0059] Specifically, the first pad 1 has a side wall 13 disposed between the first top surface 11 and the first bottom surface 12. The side wall 13 is provided with a plurality of first fixing positions, and the first bottom surface 12 is provided with a plurality of second fixing positions. The foot limiting member includes at least two foot restraint straps. The two ends of the foot restraint straps can be detachably connected to the first fixing position and the second fixing position respectively. When the child sits on the second top surface 21 and steps on the first bottom surface 12, both feet are fixed in the placement position by the two foot restraint straps respectively, that is, the child's feet are restrained between the foot restraint straps and the first bottom surface 12.
[0060] For example, the first fixing position and the second fixing position are the hook or loop side of the Velcro, and the two ends of the foot strap are respectively provided with the hook or loop side of the Velcro. Of course, in other embodiments, the first fixing position and the second fixing position can also be a pull buckle or other structure.
[0061] Specifically, the side 23 of the second pad 2 is provided with a leg restraint. When the child sits on the fixed blanket 5 with both legs extended and against the side 23, the leg restraint fixes the child's legs in the correct position, preventing the child from curling their legs or leaving the second pad 2. Exemplarily, the leg restraint includes a third fixing position and a leg strap. The third fixing position can be the hook or loop side of Velcro, and the leg strap has the loop or hook side of Velcro. When the legs are against the side 23, the leg strap restrains the legs and fixes them to the third fixing position, thus limiting the child's legs. Of course, in other embodiments, the third fixing position can also be a pull-button structure, etc., depending on actual needs.
[0062] In this embodiment, arrow markings 7 are provided on the side 13 of the first pad 1, the side 23 of the second pad 2, and the side of the middle pad 3. The arrow markings 7 on the side 13 of the first pad 1 point to the first connector 14, the arrow markings 7 on the side 23 of the second pad 2 point to the second connector 24, and the arrow markings 7 on the side of the middle pad 3 point to the third connector 31 that connects to the first pad 1 or the second pad 2. During assembly, the assembly direction can be quickly identified according to the arrow markings 7, saving assembly time.
[0063] The following is the method of using the child sitting posture training device provided in this embodiment:
[0064] For long-sitting posture training, the corrective components are positioned with the first pad 1 on the tabletop, above the second pad 2. Depending on the child's height and posture, a middle pad 3 may or may not be added. The child sits on the fixation mat 5, with their body against the sides of the corrective components and their legs against the two angled sides 23. Two leg straps are then used to secure the legs to the corresponding third fixation points. The backrest 4 is placed behind the child to help them straighten their back. Toys or other items can be placed on the top surface 11 to attract the child's attention.
[0065] For sitting posture training, the corrective components are arranged with the first pad 1 in the support position, that is, the first pad 1 is located under the second pad 2. Depending on the child's height and posture, the middle pad 3 may or may not be added. The child sits on the second top surface 21 of the second pad 2, with both legs resting against the two sides 23 set at an angle, and both feet stepping on the first bottom surface 12 of the first pad 1. Then, the two foot restraints are wrapped around the two insteps and fixed to the corresponding first and second fixation positions.
[0066] For posture training, the corrective components are positioned with the first pad 1 on the tabletop, above the second pad 2. Depending on the child's height and posture, an intermediate pad 3 may or may not be added.
