Description

[Technical Field]

[0001] This utility model relates to a child riding device. [Background Technology]

[0002] Child seating devices, such as high chairs, are common products designed for children, allowing them to eat independently. While these devices typically offer height adjustment, the entire seat and backrest are raised or lowered at the same time; the backrest itself remains unchanged. Therefore, these devices are only suitable for very young children, as the seats become unsuitable as they grow. Consequently, a growing number of consumers desire seating devices suitable for children for several years and / or for all age groups. [Utility Model Content]

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a child riding device with a simple structure that can be used by children of all ages, thereby extending the service life of the product.

[0004] This utility model is achieved through the following technical solution:

[0005] A child riding device includes two spaced-apart front legs, each front leg connected to a rear leg. A backrest is fixedly attached to the upper end of each front leg, connecting the two legs and supporting the child's back. Each front leg also has a seat support that can slide relative to the two legs to change height. A first locking mechanism is provided between the seat support and the corresponding front leg to lock it at an appropriate height. The child riding device also includes a front frame detachably connected to the seat support and backrest. When the front frame is connected to the seat support and backrest, the front frame, seat support, and backrest form a protective space to protect the child, and the front frame prevents the seat support from moving up and down along the front legs. When the front frame is detached from the seat support and backrest, the seat support can move up and down along the front legs after the first locking mechanism is unlocked. A support tray for placing items can also be detachably connected to the front frame.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The backrest of this utility model is fixed to the upper ends of the two front legs, and the seat support is connected to the front legs and can move up and down. A first locking mechanism can lock the seat support to the front legs. When the seat support is in a higher position, a front frame can be connected between the seat support and the backrest. The front frame makes the child-rearing device convenient for smaller children, ensuring their safety while seated within the protective space. Because the front frame is connected to the backrest and seat support, it prevents the seat support from descending, thus keeping it in a higher position for the convenience and safety of smaller children. When the front frame is removed from the seat support and backrest, the height of the seat support can be adjusted by unlocking the first locking mechanism. This position is suitable for older children, who no longer require the front frame for safety. Therefore, this child-rearing device has a simple structure, is suitable for children of multiple ages, and extends the product's lifespan.

[0017] 2. Both the support tray and the front frame of this utility model are detachable. When the support tray is connected to the front frame, it can be used to place toys or bowls. When the bowl is removed from the front frame, it can be hung on the crossbar or the hook on the back leg for easy storage. Additionally, when the support tray is detached and the front frame is connected to the seat support and backrest, the child can sit on the seat support. Adults can then sit in front of the child's seat for easy interaction with the child inside the high chair. The child's seat can also be pushed to the dining table for the child to eat at. When both the bowl and the front frame are detached, the child's seat can be used as a chair. For older children, the chair can be placed next to a desk, and the child can adjust the seat to a comfortable position to study. Alternatively, the chair can be pushed to the table for meals.

Detailed Implementation Methods

[0046] The present invention will be further described below with reference to the accompanying drawings:

[0047] like Figures 1 to 5 As shown, a child riding device is available for children of different ages. It includes two spaced-apart front legs 11, each front leg 1 connected to a rear leg 12. A backrest 13 is fixedly attached to the upper end of the two front legs 11, connecting the two legs and supporting the child's back. A seat support 14 is also provided on the two front legs 11, which can slide relative to the two legs to change its height. A first locking mechanism 21 is provided between the seat support 14 and the corresponding front leg 11 to lock it at an appropriate height. The child riding device also includes a front frame 15 that can be detachably connected to the seat support 14 and the backrest 13. When the front frame 15 is connected to the seat support 14 and the backrest 13, the front frame 15, the seat support 14 and the backrest 13 form a protective space 100 that can protect the child, and the front frame 15 can prevent the seat support 14 from moving up and down along the front legs 11. When the front frame 15 is detached from the seat support 14 and the backrest 13, the seat support 14 can move up and down along the front legs 11 after the first locking mechanism 21 is unlocked. When the seat support 14 is in the higher position, a front frame 15 can be connected between the seat support 14 and the backrest 13. The front frame 15 makes the child-sitting device convenient for smaller children to use, ensuring their safety while seated within the protective space 100. Because the front frame 15 is connected to the backrest 13 and the seat support 14, it prevents the seat support 14 from descending, thus keeping it in a higher position for the convenience and safety of smaller children. When the front frame 15 is removed from the seat support 14 and the backrest 13, the height of the seat support 14 can be adjusted by unlocking the first locking mechanism 21. This position is suitable for older children, who no longer require the protection of the front frame 15 for safety.

[0048] like Figures 1 to 5 As shown, a support tray 16 for placing items can be detachably connected to the front frame 15, allowing children to place toys for play or place bowls for meals on the support tray 16. A crossbar 17 connects the two rear legs 12, and a hook-on part 18 is provided on the crossbar 17 or the rear legs 12. The support tray 16 has a connection position 161 that can connect with the hook-on part 18 when it is detached from the front frame 15. When the child seat needs to be parked directly at the table, the support tray 16 can be removed and hooked onto the crossbar 17 or the rear legs 12 for easy storage.

[0049] like Figures 22 to 24 As shown, the seat support 14 includes a support frame 141, with support seats 142 at both ends of the support frame 141 that can slide relative to the front legs 11. A support plate 143 is connected to the support frame 141. The first locking mechanism 21 includes a plurality of first slots 211 arranged along the front legs 11. The support seat 142 is provided with a first locking block 212 that can move laterally and engage or disengage from the first slots 211. The support seat 142 is also provided with an exposed first pressing block 213 that can push the first locking block 212 away from the first slots 211 when pressed. The first pressing block 213 is provided with a first inclined surface 216. The first locking block 212 is provided with a mating part 217 that abuts against the first inclined surface 216. A first elastic element 214 that can push the first locking block 212 to slide back to its original position is provided between the support seat 142 and the first locking block 212. A first return spring 215 that can push the first pressing block 213 to slide back to its original position is provided between the support seat 142 and the first pressing block 213. Pressing the first pressing block 213 will push the first inclined surface 216 against the mating part 217, causing the first locking block 212 to disengage from the first locking groove 211. Once disengaged, the first locking mechanism 21 is unlocked, and the seat support 14 can be adjusted up and down. Of course, if the front frame 15 is connected to the seat support 14 and the backrest 13, the height of the seat support 14 cannot be adjusted even if the first locking mechanism 21 is unlocked, due to the connection between the front frame 15 and the fixed backrest 13. This allows the seat support 14 to remain at a higher height for safe use by younger children.

[0050] like Figure 23 As shown, the support base 142 is provided with a horizontal protrusion 144 that allows the support base 142 to slide up and down along the front leg 11 when the first pressing block 213 is pressed and unlocked. Therefore, the user can press the first pressing block 213 with the horizontal protrusion 144 as a fulcrum, and once unlocked, the height of the seat support 14 can be adjusted by operating the horizontal protrusion 144, making the operation very convenient and quick.

[0051] like Figures 26 to 28As shown, the front leg 11 and the corresponding rear leg 12 are rotatably connected and can be unfolded or folded relative to each other. A second locking mechanism 32 is provided between the front leg 11 and the rear leg 12. The second locking mechanism 32 includes a second locking seat 321 provided on the front leg 11, and a second slot 322 provided on the second locking seat 321. A second locking block 323 is provided in the rear leg 12, which can slide along it and engage or disengage with the second slot 322. The second locking block 323 is provided with a second inclined surface 324. The rear leg 12 is also connected to... A second pressing block 325 that can be pressed laterally is provided. The second pressing block 325 is provided with a second inclined surface 326 that abuts against the second inclined surface 324 and can push the second locking block 323 out of the second locking groove 322 when the second pressing block 325 is pressed laterally. A second return spring 327 that can push the second pressing block 325 to slide back to its original position is provided between the rear leg 12 and the second pressing block 325. A second elastic element 328 that can push the second locking block 323 to slide back to its original position is also provided inside the rear leg 12. When the second pressing block 325 is pressed, the second inclined surface 326 on it pushes the second inclined surface 324 on the second locking block 323, thereby causing the second locking block 323 to slide and disengage from the second locking groove 322 on the second locking seat 321. At this time, the second locking mechanism 32 is unlocked, and the rear leg 12 can rotate relative to the front leg 11 and fold onto the front leg 11 for easy storage and transportation packaging of the product.

[0052] like Figure 5 , Figure 8 , Figure 10 , Figure 17 and Figure 20As shown, the front frame 15 includes a U-shaped upper frame 151, with hooks 152 at both ends of the upper frame 151. The backrest 13 has locking holes 131 that can engage with the corresponding hooks 152. A front stop bar 153 extending vertically is provided at the center of the front end of the upper frame 151. The seat support 14 has a locking position 145. The lower end of the front stop bar 153 can be detachably inserted into the locking position 145. The seat support 14 has a locking mechanism that locks the seat support 14 to the front stop bar 153 when the front stop bar 153 is inserted into the locking position 145. The three locking mechanisms 43 include a third slot 431 located at the lower end of the front stop lever 153, a rotating rod 432 that can rotate relative to the seat support 14, a third locking block 433 that can engage or disengage with the third slot 431 when the rotating rod 432 rotates, an exposed third pressing block 434 for pressing, and a third return spring 435 that can push the rotating rod 432 to rotate and reset between the seat support 14 and the rotating rod 432. When the third pressing block 434 is pressed, the rotating rod 432 rotates relative to the seat support 14. During the rotation, the third locking block 433 on the rotating rod 432 disengages from the third locking groove 431 on the front stop 153. At this time, the front stop 153 can be pulled out of the locking position 145. During the pulling process, the upper frame 151 will also rotate relative to the backrest 13, so that the hook 152 exits from the locking hole 131 of the backrest 13. At this time, the front frame 15 is removed.

[0053] like Figure 7 , Figure 12 and Figure 13 As shown, the front stop lever 153 is detachably connected to the upper frame 151, facilitating product packaging. Users can connect the front stop lever 153 to the upper frame 151 themselves after purchase. A seventh locking mechanism 57 is provided between the upper frame 151 and the front stop lever 153. The seventh locking mechanism 57 includes seventh slots 571 symmetrically arranged on the upper frame 151. The upper ends of the front stop lever 153 have exposed seventh blocks 572 that can move laterally within them to engage or disengage with the corresponding seventh slots 571. The seventh blocks 572 have a seventh inclined surface 574. A seventh return spring 573 is provided between the seventh blocks 572 and the front stop lever 153 to push the seventh blocks 572 to move and reset. During assembly, simply insert the front stop lever 153 upwards. When the seventh inclined surface 574 touches the upper frame 151, it will be pressed down, and the seventh return spring 573 will be compressed. When the front stop lever 153 moves to the point where the seventh locking block 572 and the seventh locking slot 571 are aligned, the seventh return spring 573 extends and pushes the seventh locking block 572 to engage with the seventh locking slot 571.

[0054] The first locking mechanism 21 is located between the support base 142 and the front leg 11. The support plate 143 is slidably connected to the support frame 141 and can move back and forth. A fourth locking mechanism 64 for locking the support plate 143 and the support frame 141 is provided between them. The fourth locking mechanism 64 includes a fixed base 641 on the support frame 141. The fixed base 641 has a plurality of fourth slots 642 along the front and rear direction. The support plate 143 includes an upper plate 1431 and a lower plate 1432. The upper part of the fixed base 641 is inserted into the support plate 143. The lower plate 1432 is provided with a moving block 643 that can move back and forth relative to it. The moving block 643 is provided with an exposed fourth operating block 644. The plate 1432 is also provided with a locking block 645 connected to the moving block 643 and capable of being moved laterally by the moving block 643 when the moving block 643 moves backward. The locking block 645 is provided with a fourth locking block 646 that can engage or disengage with the fourth locking slot 642 when it moves laterally. A fourth return spring 647 is provided between the lower plate 1432 and the moving block 643 to push the moving block 643 to slide back to its original position. The moving block 643 is provided with an upwardly protruding protrusion 648, and the locking block 645 is provided with an inclined groove 649 for the protrusion 648 to be inserted. When the moving block 643 moves back and forth, the protrusion 648 pushes against the groove wall of the inclined groove 649, causing the locking block 645 to move laterally. When the child is small, the front frame 15 will be used for protection, and the support plate 143 will be set further back. When the child is older and the front frame 15 is not needed, the support plate 143 needs to be adjusted forward to provide sufficient seating support area for the child's comfort and safety. Pull the fourth operating block 644 backward, and the moving block 643 moves backward. The protrusion 648 on the moving block 643 pushes against the inclined groove 649 wall on the locking block 645, causing the locking block 645 to move laterally. At this time, the fourth locking block 646 on the locking block 645 disengages from the fourth locking groove 642, and the position of the support plate 143 can be adjusted back and forth.

[0055] like Figures 8 to 11 ,as well as Figure 14 and Figure 15As shown, the upper end of the front frame 15 has an arc surface 154, and the lower side of the support plate 16 is provided with an opening groove 162 that matches the arc surface 154. When the front frame 15 is connected to the support plate 15, the opening groove 162 is locked on the arc surface 154. A fifth locking mechanism is provided between the support plate 16 and the front frame 15. The fifth locking mechanism includes a vertical groove 751 located at the rear end of the front frame 15 and a horizontal groove 752 communicating with the vertical groove 751. The support plate 16 is provided with a locking block 753 that can enter from the vertical groove 751 and engage with the horizontal groove 752. The front end of the front frame 15 is also provided with a fifth slot 754. The support plate 16 is provided with a sliding block 755 that can slide relative to it. The sliding block 755 is provided with a fifth locking block 756 that can engage with the fifth slot 754 when the locking block 753 engages with the horizontal groove 752 and the opening groove 162 engages with the arc surface 154. The sliding block 755 is also provided with an exposed fifth operating block 757 that can operate its sliding. A fifth return spring 758 that can push the sliding block 755 to slide back to its original position is provided between the sliding block 755 and the support plate 16. When the support plate 16 needs to be disassembled, the fifth operating block 757 is pulled outward, causing the sliding block 755 to disengage the fifth locking block 756 from the fifth locking groove 754. Once disengaged, the support plate 16 can be slightly rotated upward, disengaging the opening groove 162 of the support plate 16 from the arc surface 154. At this time, the locking block 753 can also exit from the horizontal groove 752 and the vertical groove 751. When assembling the support plate 16 onto the front frame 15, the locking block 753 is pushed downward into the vertical groove 751 and forward into the horizontal groove 752. Then, the support plate 16 is rotated, causing the opening groove 162 to engage with the arc surface 154, and the fifth locking block 756 to engage with the fifth locking groove 754. Because the opening groove 162 is engaged with the arc surface 154, the support plate 16 cannot move back and forth in this state. Even if the first locking block 756 disengages from the fifth locking groove 754, the locking block 753 can still be prevented from disengaging from the horizontal groove 752. The support plate 16 can only be removed when the first card block 756 is disengaged from the fifth card slot 754 and the support plate 16 is rotated downwards, so that the connection of the support plate 16 is relatively stable and reliable.

[0056] like Figure 1 and Figure 15As shown, a foot pedal 19 that can move up and down relative to the front leg 11 is also connected to the front leg 11 for children to step on. A sixth locking mechanism 86 is provided between the foot pedal 19 and the front leg 11. The sixth locking mechanism 86 includes a plurality of sixth slots 861 provided on the front leg 11. Sliding seats 862 are provided at the left and right ends of the foot pedal 19. A sixth locking block 863 is provided in the sliding seat 862, which can slide relative to it and engage or disengage with the sixth slots 861. The sliding seat 862 is also provided with an exposed and pressable sixth pressing block 864. The sixth pressing block 864 is provided with an inclined hole 865. The sixth locking block 863 is provided with a connecting shaft 866 that passes through the inclined hole 865 and can be pushed by the wall of the inclined hole 865 when the sixth pressing block 864 is pressed. A sixth return spring 867 is also provided between the sixth pressing block 864 and the sliding seat 862, which can push the sixth pressing block 864 to slide back to its original position. Pressing the sixth pressing block 846 pushes the connecting shaft 866 through the inclined hole 865, causing the sixth locking block 863 to move laterally and disengage from the sixth locking slot 861.
