Description

Technical Field

[0001] This invention relates to the field of stroller technology, and more particularly to a stroller with a 360-degree quickly adjustable seat. Background Technology

[0002] Strollers are a common piece of equipment for infants and toddlers, allowing them to sit comfortably in the seat and be moved by the parent. Most existing seats are fixed in place, with the child typically facing only forward or towards the parent, making it difficult to meet the needs of multi-angle use. Therefore, strollers with adjustable and rotating seats have been developed to meet these needs. However, most adjustment methods require complex latching mechanisms, making quick adjustments difficult for parents and requiring considerable effort. Simple rotating mechanisms, on the other hand, offer poor seat stability. Therefore, there is a need to design a stroller that is effortless, allows for quick one-handed adjustment, enables 360-degree seat rotation, and has good structural stability, meeting current usage requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a stroller with a 360-degree adjustable seat.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A 360-degree quickly adjustable child stroller includes a frame, a seat, and a foot pedal. The frame has a support base and at least two locking interfaces. The seat includes a base, a rotating seat, an adjustment component, and a locking component. The base is rotatably mounted on the support base via the rotating seat. The base has an adjustment groove, a movable seat, and a rotating seat. The adjustment component is movably installed in the adjustment groove. The movable seat is located in the adjustment groove and has a movable opening that aligns with the locking interfaces. The locking component is movably installed on the movable seat, with its bottom passing through the movable opening and engaging with the locking interfaces to restrict the rotation of the base. The foot pedal is rotatably mounted on the rotating seat and has an adjustment part for pushing the adjustment component to adjust the locking component for engaging or disengaging.

[0006] Furthermore, the base has a side opening on its side wall that communicates with the adjustment groove. The side opening faces the foot pedal. By rotating the foot pedal upward, its adjustment part abuts against the adjustment member and pushes it to move towards the movable seat. This pushes the locking member to move upward along the movable opening and disengage from the locking interface. The base is then rotated 0-360 degrees along the rotating seat.

[0007] Furthermore, one end of the adjusting member is provided with an extension portion, which passes through the side opening and cooperates with the adjusting member. The other end is provided with an inclined surface that cooperates with the locking member to push it upward. The locking member is provided with a push rod that cooperates with the inclined surface. The adjusting member drives the inclined surface to push the push rod, and the push rod moves upward along the inclined surface and the opening.

[0008] Furthermore, the movable seat has rod openings on both sides, the locking member has two push rods installed in the two rod openings respectively, the inclined surface has two parts that cooperate with the two push rods respectively, and the two inclined surfaces have a certain distance to form a notch that is adapted to the movable seat.

[0009] Furthermore, the bottom of the lock is provided with a snap-fit ​​part that fits into the card interface.

[0010] Furthermore, the foot pedal is provided with a rotating part that is rotatably mounted to the rotating seat. The rotating part has rotating openings on both sides that are opposite to the rotating seat and a rotating shaft is rotatably mounted thereon. The adjusting part is provided on the rotating part and faces the adjusting groove.

[0011] Furthermore, the adjustment part is a protruding structure that abuts and cooperates with the adjustment member.

[0012] Furthermore, both the base and the support are provided with rotating openings for mounting the rotating seat. The rotating seat includes an upper plate, a seat body, and a lower plate. The upper plate covers the rotating opening at the top of the base, the seat body is installed in the rotating opening of the support, and the lower plate covers the bottom of the seat body. The upper plate, the seat body, and the lower plate are all provided with aligned mounting holes and have mounting rods for fixing inside.

[0013] Furthermore, the base has an upper groove at its bottom for mounting a support seat, and a limiting protrusion ring for limiting the position is provided in the upper groove and arranged around the rotating opening. The support seat has a limiting groove around its rotating opening and adapted to the limiting protrusion ring. The limiting protrusion ring is embedded in the limiting groove. The base has a locking block on the inner wall of its rotating opening, and the seat body has a locking slot adapted to the locking block.

[0014] Furthermore, the support seat has a limiting flange on the inner wall of its rotating opening, and the seat body has a snap-fit ​​flange at its bottom that engages with the limiting flange.

[0015] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0016] 1. The seat of this invention is rotatably mounted on the support seat of the vehicle frame via a rotating base. A foot pedal is operated with one hand, rotating on the rotating base and moving upwards or downwards. When the foot pedal rotates upwards, the adjusting part of the foot pedal rotates upwards, pushing the adjusting component to move within the adjusting groove. The adjusting component, under force, moves towards the movable seat and pushes the locking component upwards at the movable opening, disengaging from the locking interface. At this point, the seat can rotate 360 ​​degrees on the support seat. After rotating to the predetermined position, rotating the foot pedal downwards moves the adjusting part away from the adjusting component, which in turn moves away from the movable seat. The locking component resets, moves downwards along the movable opening, and engages with the locking interface, restricting the seat's position and preventing rotation. This ingenious structure allows for seat rotation and fixation with one hand, meeting usage requirements.

[0017] 2. The base of the present invention is embedded in the limiting groove of the support seat through the limiting protrusion ring, and the rotating seat is engaged with the locking block of the base through the locking slot of its seat body, so that the seat can rotate stably on the support seat and is not easy to separate, thus meeting the usage requirements and safety.

[0027] Example

[0028] Cooperate Figures 1 to 5 As shown, this invention discloses a 360-degree quickly adjustable child stroller, including a frame 1, a seat 2, and a foot pedal 3. The frame 1 is provided with a support base 4 and at least two locking interfaces 41. The seat 2 includes a base 21, a rotating seat 22, an adjusting member 23, and a locking member 24. The base 21 is rotatably mounted on the support base 4 via the rotating seat 22. The base 21 is provided with an adjusting groove 211, a movable seat 212, and a rotating seat 213. The adjusting member 23 is movably installed in the adjusting groove 211. The movable seat 212 is disposed in the adjusting groove 211 and is provided with a movable opening 214 that aligns with the locking interfaces 41. The locking member 24 is movably installed in the movable seat 212, and its bottom passes through the movable opening 214 and engages with the locking interfaces 41 to restrict the rotation of the base 21. The foot pedal 3 is rotatably mounted on the rotating seat 213 and is provided with an adjusting part 31 for pushing the adjusting member 23 to adjust the locking member 24 to engage or disengage.

[0029] The support base 4 is mounted on the frame 1, which is existing technology and will not be described in detail in this embodiment; the seat 2 also includes a seat cushion board for children to sit on, which is covered on the base 21 and is installed on the base by bolts.

[0030] Seat 2 is rotatably mounted on support seat 4 of frame 1 via rotating seat 22. Foot pedal 3 is operated with one hand, rotatably mounted on rotating seat 213 and rotated up or down. When foot pedal 3 rotates up, adjusting part 31 of foot pedal 3 rotates up and pushes adjusting part 23 to move in adjusting groove 211. Adjusting part 23 is forced to move towards movable seat 212 and pushes locking part 24 to move upward in movable opening 214 and disengage from locking interface 41. At this time, seat 2 can rotate 360 ​​degrees on support seat 4. When rotated to the predetermined position, foot pedal 3 is rotated down, adjusting part 31 moves away from adjusting part 23, adjusting part 23 moves away from movable seat 212, locking part 24 resets and moves downward along movable opening 214 and engages with locking interface 41, restricting the position of seat 2 and preventing it from rotating. The structure is ingenious, and seat 2 can be rotated and fixed with one hand, meeting the usage requirements.

[0031] The base 21 has a side opening 215 on its side wall that communicates with the adjustment groove 211. The side opening 215 faces the foot pedal 3. By rotating the foot pedal 3 upward, the adjustment part 31 is driven to abut against the adjustment member 23 and push it to move towards the movable seat 212. The locking member 24 is pushed to move upward along the movable opening 214 to disengage the card interface 41. The base 21 is rotated 0-360 degrees along the rotating seat 22.

[0032] One end of the adjusting member 23 is provided with an extension 231, which is a plate structure integrally formed with the adjusting member 23. The extension 231 passes through the side opening 215 and cooperates with the adjusting member 31. The other end is provided with a sloping part 232 that cooperates with the locking member 24 to push it to move upward. In this embodiment, the sloping part 232 is preferably a triangular plate, which is integrally formed with the adjusting member 23. Its function is to have a certain inclined surface, the inclination angle of which is not limited, to push the locking member 24 to move along its inclined surface. The locking member 24 is provided with a push rod 241 that cooperates with the sloping part 232. The push rod 241 is integrally formed with the locking member 24. The adjusting member 23 drives the sloping part 232 to push the push rod 241, and the push rod 241 moves upward along the sloping part 232 and the moving opening 214.

[0033] The movable seat 212 has rod openings 216 on both sides. The rod openings 216 can be a limited structure, i.e., an O-shaped structure, or a non-limited structure, i.e., a U-shaped structure. The locking member 24 has two push rods 241 and is installed in the two rod openings 216 respectively. The inclined part 232 has two parts and cooperates with the two push rods 241 respectively. The two inclined parts 232 have a certain distance to form a notch 233 that is adapted to the movable seat 212. After the adjusting member 23 moves toward the movable seat 212, the movable seat 212 is embedded in the notch 233, and the inclined parts 232 are arranged on both sides.

[0034] The bottom of the lock 24 is provided with a card connector 242 that fits into the card interface 41.

[0035] The foot pedal 3 is provided with a rotating part 32 that is rotatably mounted to the rotating seat 213. The rotating part 32 has a rotating opening on both sides that is opposite to the rotating seat 213 and a rotating shaft is rotatably mounted thereon. There are two rotating seats 213 that are arranged opposite to each other. The foot pedal 3 is rotatably mounted between the two rotating seats 213 through its rotating part 32. The adjusting part 31 is provided on the rotating part 32 and faces the adjusting groove 211.

[0036] The adjustment part 31 is a protruding structure that abuts against the adjustment member 23. During the upward rotation of the foot pedal 3, this structure abuts against and pushes the extension part 231 to drive the adjustment member 23 to move inward.

[0037] In this embodiment, the adjustment member 23 can be reset by providing a spring in the adjustment groove 211 to push the adjustment member 23 to move and reset towards the side opening 215. This spring can be provided in the notch 233 and abut against the movable seat 212. Alternatively, a spring can be provided on the top of the locking member 24 to push it downward. After the foot pedal 3 is rotated downward to reset, the locking member 24 loses the upward thrust of the inclined part 232, and the spring pushes it downward and pushes the inclined part 232, the adjustment member 23, and the extension 231 outward, thus resetting the adjustment member 23. This embodiment is not limited to this method.

[0038] Both the base 21 and the support 4 are provided with rotating openings 5 ​​for mounting the rotating seat 22.

The upper plate 221, the seat body 222 and the lower plate 223 are all provided with aligned mounting holes and mounting rods for fixing. The mounting rods can be threaded into the mounting holes or fixed by nuts, so that the upper plate 221, the seat body 222 and the lower plate 223 are not separated. The base 21 is mounted on the support 4 through the rotating seat 22 and rotates at the rotating opening 5. The upper plate 221 is the base 21 mounted on the seat body 222.

[0039] The number of card interfaces 41 is not limited in this embodiment. Each card interface 41 is arranged around the rotating port 5. When there are two card interfaces 41, they are arranged at the front and rear ends of the support base 4 to meet the usage requirements of the seat 2 facing forward and the seat 2 facing backward.

[0040] The base 21 has an upper groove 217 at its bottom for mounting the support base 4. The upper groove 217 has a limiting protrusion 218 for limiting the position, which is arranged around the rotation opening 5. The support base 4 has a limiting groove 42 around its rotation opening and adapted to the limiting protrusion 218. The limiting protrusion 218 is embedded in the limiting groove 42. The base 21 has a locking block 219 on the inner wall of its rotation opening 5. The seat body 222 has a locking slot 224 adapted to the locking block 219. The locking block 219 is engaged in the locking slot 224. When the base 21 rotates, the seat body 222 rotates with it.

[0041] The support base 4 has a limiting flange 43 on the inner wall of its rotating opening, and the base body 222 has a snap-fit ​​flange 225 at its bottom that engages with the limiting flange 43.

[0042] In this embodiment, the base 21 is embedded in the limiting groove 42 of the support seat 4 through the limiting protrusion 218, and the rotating seat 22 is engaged with the locking block 219 of the base 21 through the locking slot 224 of its seat body 222, so that the seat 2 can rotate stably on the support seat 4 and is not easy to separate, thus meeting the usage requirements and safety.

[0043] In this embodiment, the foot pedal 3 is provided with two footrests, and there is a certain gap between the two footrests for cooperating with the push handle of the frame 1. When the seat 2 is rotated to face the push handle, the foot pedal 3 rotates downward through the gap.

[0044] In this embodiment, the one-handed operation means that the user rotates the foot pedal upward with one hand, the base is released from the locking state with the support, and the foot pedal is rotated 360 degrees counterclockwise or clockwise.

[0045] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
