Abstract
Description
Technical Field
[0001] This invention relates to a seating device. It also relates to a stroller. Background Technology
[0002] Strollers, high chairs, and other similar products are common items used during a child's growth. These products all have a seating mechanism to accommodate growth. The seating mechanism mainly includes a seat and a leg support frame that rotates and connects to the front of the seat. By rotating the leg support frame, it can be positioned in different ways, allowing the child's legs or feet to be supported and making the ride more comfortable.
[0003] To position the leg support, a locking mechanism is provided between the seat and the leg support. This mechanism includes a left locking component on the left side of the seat and a right locking component on the right side. When adjusting the leg support, users typically need to press the unlock buttons on both sides of the seat simultaneously with both hands, adjust the leg support to the desired position, and then relock it. However, this unlocking operation requires both hands to operate the unlock buttons simultaneously, making it inconvenient for users to adjust the leg support position, especially when holding other items, making one-handed operation difficult.
[0004] Therefore, the present invention was developed in response to the above-mentioned shortcomings. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a seating device with a simple structure and convenient adjustment of the leg support position. Users can operate the adjustment of the leg support position with one hand, bringing convenience to daily life.
[0006] The present invention also provides a stroller that uses the aforementioned seating device, and the adjustment of the leg support frame position can be operated with one hand, making it very convenient for users to use the stroller.
[0007] This invention is achieved through the following technical solution:
[0008] A seating device includes a seat and a leg support rotatably connected to the front side of the seat. A locking structure is provided between the leg support and the seat to lock their relative positions. The locking structure includes a left locking component located on the left side of the seat and a right locking component located on the right side of the seat. The seating device also includes a left unlocking member for unlocking the left locking component and a right driving member for unlocking the right locking component. A linkage component connected to the left and right locking components is provided within the seat. The linkage component is movably connected to the seat and configured such that when the left unlocking member is operated alone to unlock the left locking component, the linkage component drives the right locking component to unlock; and when the right unlocking member is operated alone to unlock the right locking component, the linkage component drives the left locking component to unlock.
[0009] The seat portion has a left connecting shell on the left side and a right connecting shell on the right side. The leg support frame includes a left connecting seat and a right connecting seat spaced apart from each other. A support rod is provided between the left connecting seat and the right connecting seat. The left connecting seat and the left connecting shell are rotatably connected, and the right connecting seat and the right connecting shell are rotatably connected. The left locking component is located between the left connecting shell and the left connecting seat, and the right locking component is located between the right connecting shell and the right connecting seat.
[0010] The left locking assembly includes a left locking position on the left connecting seat, a left locking block that can engage or disengage from the left locking position is slidably disposed within the left connecting shell, a left unlocking member is connected to the left locking block and can drive the left locking block to disengage from the left locking position, and a first return spring that can push the left locking block to reset is disposed between the left locking block and the left connecting shell; the right locking assembly includes a right locking position on the right connecting seat, a right locking block that can engage or disengage from the right locking position is slidably disposed within the right connecting shell, a right unlocking member is connected to the right locking block and can drive the right locking block to disengage from the right locking position, and a second return spring that can push the right locking block to reset is disposed between the right locking block and the right connecting shell; one end of the linkage assembly is connected to the left locking block and the other end is connected to the right locking block.
[0011] The linkage assembly includes a rotating block rotatably connected to the seat. The rotating block has a first connecting part and a second connecting part at an eccentric position. A left linkage rod is provided between the left locking block and the first connecting part, with one end engaging with the left locking block and the other end movably connected to the first connecting part. A right linkage rod is provided between the right locking block and the second connecting part, with one end engaging with the right locking block and the other end movably connected to the second connecting part. When the left unlocking component drives the left locking block to disengage from the left locking position, the left locking block pushes the rotating block to rotate via the left linkage rod, causing the rotating block to pull the right locking block to disengage from the right locking position via the right linkage rod. When the right unlocking component drives the right locking block to disengage from the right locking position, the right locking block pushes the rotating block to rotate via the right linkage rod, causing the rotating block to pull the left locking block to disengage from the left locking position via the left linkage rod.
[0012] The first connecting part and the second connecting part are protruding posts arrayed on the rotating block. The left linkage rod is provided with a left opening groove that movably engages with the protruding posts, and the right linkage rod is provided with a right opening groove that movably engages with another protruding post.
[0013] The left locking block includes a left locking part that engages with the left locking position. The left locking part has a left protruding rod that passes laterally through the left connecting shell. The left protruding rod is engaged with the left linkage rod. The right locking block includes a right locking part that engages with the right locking position. The right locking part has a right protruding rod that passes laterally through the right connecting shell. The right protruding rod is engaged with the right linkage rod.
[0014] The left locking part includes a left body with multiple left teeth along the circumferential direction. The left locking position is a left locking groove on the left connecting seat along the circumferential direction that can engage or disengage with the left teeth. The left connecting shell has a left engaging groove along the circumferential direction that engages with the left teeth. The left protruding rod is connected to the left body. The first return spring is disposed between the left body and the left connecting shell. The right locking part includes a right body with multiple right teeth along the circumferential direction. The right locking position is a right locking groove on the right connecting seat along the circumferential direction that can engage or disengage with the right teeth. The right connecting shell has a right engaging groove along the circumferential direction that engages with the right teeth. The right protruding rod is connected to the right body. The second return spring is disposed between the right body and the right connecting shell.
[0015] The left unlocking component is a left button that is slidably connected to the left connecting seat and can push the left locking block to move; the right unlocking component is a right button that is slidably connected to the right connecting seat and can push the right locking block to move.
[0016] The left linkage rod is provided with a horizontal left guide groove, the seat part is provided with a left guide post passing through the left guide groove, the right linkage rod is provided with a horizontal right guide groove, and the seat part is provided with a right guide post passing through the right guide groove.
[0017] A stroller includes a frame on which a seating device as described above is connected, and a backrest is also connected to the rear side of the seat.
[0018] Compared with the prior art, the present invention has the following advantages:
[0019] 1. The seat portion of this invention is movably connected to a linkage component that connects to both the left and right locking components. When the left unlocking component is operated alone to unlock the left locking component, the linkage component will cause the right locking component to unlock in conjunction. Conversely, when the right unlocking component is operated alone to unlock the right locking component, the linkage component will cause the left locking component to unlock in conjunction. By operating either the left or right unlocking component, the linkage unlocking of the left and right locking components can be achieved. This one-handed operation significantly improves convenience and adaptability, allowing users, whether left-handed or right-handed, or while holding items, to easily unlock and adjust the leg support.
[0020] 2. When the left button of this invention pushes the left locking block to disengage from the left locking position, the left locking block pushes the left linkage rod to move. The left linkage rod pushes the rotating block to rotate relative to the seat. During the rotation, the rotating block pulls the right linkage rod to move through its second connecting part. The right linkage rod then pulls the right locking block to disengage from the right locking position. Therefore, pressing the left button alone can disengage the left locking block from the left locking position and the right locking block from the right locking position. The rotating block design converts the unidirectional movement of the left button into the opposite movement of the left and right locking blocks, thus achieving synchronous unlocking of the left and right locking components. The design is very ingenious. Similarly, when the right button is pressed, the right locking block disengages from the right locking position. At this time, the right linkage rod pushes the rotating block to rotate, and the rotating block pulls the left locking block to disengage from the left locking position through the left linkage rod. When the user needs to adjust the position of the leg support frame, they only need to press the left or right button with one hand, making the operation very convenient and quick.
[0021] 3. The seating device of the present invention and the stroller using the seating device are very convenient to adjust the leg support frame, and are suitable for widespread application. Attached Figure Description

[0032] The present invention will now be further described with reference to the accompanying drawings:
[0033] like Figures 1 to 9 As shown, this embodiment provides a seating device, particularly suitable for vehicles such as strollers. It includes a seat 1 and a leg support frame 2 rotatably connected to the front of the seat 1. The leg support frame 2 supports the legs of the passenger, and its angle is adjustable relative to the seat 1 to accommodate different seating postures or folded positions. A locking structure is provided between the leg support frame 2 and the seat 1 to lock the leg support frame 2 in a desired relative position.
[0034] like Figures 2 to 9 As shown, specifically, the locking structure includes a left locking component 31 located on the left side of the seat 1 and a right locking component 32 located on the right side of the seat 1. The seating device also includes a left unlocking member 41 for unlocking the left locking component 31 and a right unlocking member 42 for unlocking the right locking component 32. In particular, a linkage component 5 is provided inside the seat 1, which is connected to the left locking component 31 and the right locking component 32 respectively, and is movably connected to the seat 1. The linkage component 5 is configured such that when the user operates the left unlocking member 41 alone to unlock the left locking component 31, the linkage component 5 can simultaneously drive the right locking component 32 to unlock; conversely, when the user operates the right unlocking member 42 alone to unlock the right locking component 32, the linkage component 5 can also drive the left locking component 31 to unlock. This design achieves the unlocking effect of single-sided operation and double-sided linkage, allowing for convenient unlocking regardless of whether the user is left-handed or right-handed, or in scenarios where one hand is used (e.g., holding a child with the other hand), greatly improving the ease of operation.
[0035] like Figures 2 to 9As shown, furthermore, to facilitate installation and achieve a stable rotational connection, a left connecting shell 11 is fixedly installed on the left side of the seat portion 1, and a right connecting shell 12 is fixedly installed on the right side of the seat portion 1. The leg support frame 2 includes a left connecting seat 21 and a right connecting seat 22 spaced apart from each other, with a support rod 23 for supporting the legs connected between the left connecting seat 21 and the right connecting seat 22. The left connecting seat 21 is rotatably connected to the left connecting shell 11 via a pivot, and the right connecting seat 22 is rotatably connected to the right connecting shell 12 via another pivot. Thus, the leg support frame 2 can rotate as a whole relative to the seat portion 1. The left locking component 31 is specifically disposed between the left connecting shell 11 and the left connecting seat 21 to lock their relative rotation; the right locking component 32 is disposed between the right connecting shell 12 and the right connecting seat 22. This symmetrical arrangement ensures uniform stress on the structure and improves the stability of the locking and unlocking process.
[0036] like Figure 5 and Figure 6 As shown, the left locking assembly 31 includes a left latch 311 disposed on the left connecting seat 21. A left latch 312 is slidably disposed inside the left connecting shell 11, which can engage with the left latch 311 to lock or disengage to unlock. The left unlocking member 41 is connected to the left latch 312, thereby driving the left latch 312 to move and disengage from the left latch 311. In addition, a first return spring 313 is disposed between the left latch 312 and the left connecting shell 11, which can push the left latch 312 back to the position engaged with the left latch 311. Similarly, the right locking assembly 32 includes a right latch 321 disposed on the right connecting seat 22. A right latch 322 is slidably disposed inside the right connecting shell 12, which can engage or disengage from the right latch 321. The right unlocking member 42 is connected to the right latch 322 to drive it to unlock. A second return spring 323 is provided between the right locking block 322 and the right connecting shell 12 to push the right locking block 322 to reset. One end of the linkage component 5 is connected to the left locking block 312, and the other end is connected to the right locking block 322. This design, which connects the left and right locking blocks 312 and 322 through the linkage component 5, ensures the synchronicity of the unlocking actions on both sides, avoids the twisting or jamming of the leg support frame 2 caused by unlocking on one side while the other side remains locked, protects the mechanical structure, and extends its service life.
[0037] like Figures 2 to 9As shown, more specifically, the linkage assembly 5 includes a rotating block 53 rotatably connected to the seat portion 1 via a rotating shaft. A first connecting portion 51 and a second connecting portion 52 are provided at an eccentric position (i.e., a non-central position) on the rotating block 53. A left linkage rod 54 is connected between the left locking block 312 and the first connecting portion 51, with one end of the left linkage rod 54 engaging with the left locking block 312 and the other end movably connected to the first connecting portion 51. A right linkage rod 55 is connected between the right locking block 322 and the second connecting portion 52, with one end of the right linkage rod 55 engaging with the right locking block 322 and the other end movably connected to the second connecting portion 52. The linkage working principle is as follows: When the left unlocking component 41 drives the left locking block 312 to move to the right and disengage from the left locking position 311, the left locking block 312 applies a pushing force to the first connecting part 51 through the left linkage rod 54 connected to it. Since the first connecting part 51 is located at the eccentric position of the rotating block 53, this force generates a torque, driving the rotating block 53 to rotate around its axis. When the rotating block 53 rotates, the second connecting part 52 on it moves accordingly, and then pulls the right locking block 322 to the left through the right linkage rod 55, causing it to disengage from the right locking position 321, thereby realizing the linkage unlocking of the right locking component 32. Conversely, when the right unlocking component 42 drives the right locking block 322 to move and unlock, the right locking block 322 drives the rotating block 53 to rotate in the opposite direction through the right linkage rod 55, and the rotating block 53 then pulls the left locking block 312 to move and unlock through the left linkage rod 54. This linkage mechanism based on rotating block 53 is ingeniously designed, compact in structure, and highly efficient in transmission. It achieves reliable bidirectional linkage with fewer parts, reducing manufacturing costs and assembly complexity.
[0038] like Figures 3 to 7 As shown, in a preferred embodiment, the first connecting portion 51 and the second connecting portion 52 are protrusions arrayed (e.g., symmetrically arranged) on the rotating block 53. Correspondingly, the end of the left linkage rod 54 is provided with a left opening groove 56 that movably engages with one of the protrusions, and the end of the right linkage rod 55 is provided with a right opening groove 57 that movably engages with the other protrusion. The engagement of the left and right opening grooves 56 and 57 with the corresponding protrusions allows the corresponding protrusions to slide relative to the groove walls of the left and right opening grooves 56 and 57 when the rotating block 53 rotates. This allows for seamless conversion between the rotational motion of the rotating block 53 and the linear motion of the left and right linkage rods 54 and 55, while ensuring effective force transmission, providing flexible movable connections, reducing motion interference, and making the operation smoother.
[0039] like Figures 3 to 7As shown, the left locking block 312 includes a left locking portion 3121 for engaging with the left locking position 311. A left protruding rod 3122, which extends laterally through the side wall of the left connecting shell 11, is connected to the left locking portion 3121. One end of the left protruding rod 3122 is fixed to the left locking portion 3121, and the other end extends to the outside of the left connecting shell 11 and is connected to the left linkage rod 54 by a snap-fit connection. Similarly, the right locking block 322 includes a right locking portion 3221 and a right protruding rod 3222, which extends laterally through the right connecting shell 12 and is snap-fitted to the right linkage rod 55. By setting the left and right protruding rods 3122 and 3222 to be connected to the corresponding left and right linkage rods 54 and 55, the assembly and connection of the internal linkage mechanism are facilitated, and the force transmission path is made direct and efficient.
[0040] like Figures 4 to 9 As shown, the left locking part 3121 includes a left body 31211, on which a plurality of left teeth 31212 are arranged circumferentially. Correspondingly, the left locking position 311 is a left locking groove (not shown separately in the figure) provided on the left connecting seat 21 and capable of engaging and locking with the left teeth 31212. At the same time, a left engaging groove 314 that mates with the left teeth 31212 is also provided circumferentially on the inner wall of the left connecting shell 11. When the left locking block 312 is in the locked position, its left teeth 31212 engage with both the left locking groove on the left connecting seat 21 and the left engaging groove 314 on the left connecting shell 11, thereby firmly fixing the relative position of the left connecting seat 21 and the left connecting shell 11. The left protruding rod 3122 is connected to the left body 31211. One end of the first return spring 313 abuts against the left body 31211, and the other end abuts against the inner wall of the left connecting shell 11, providing a return force for the left locking block 312. The right locking assembly 32 adopts a completely symmetrical structure: the right locking part 3221 includes the right body 32211, which is provided with right teeth 32212; the right locking position 321 is the right locking groove on the right connecting seat 22; the right connecting shell 12 is provided with a right engaging groove 324; the right protrusion 3222 is connected to the right body 32211; and the second return spring 323 provides the return force. Since the left teeth 31212 and the right teeth 32212 are distributed along the circumferential direction, the leg support frame 2 is allowed to be locked at multiple angle positions, providing more adjustment options.
[0041] like Figures 3 to 7As shown, in this embodiment, the left unlocking component 41 is specifically a left button 411 slidably connected to the left connecting seat 21. Pressing the left button 411 pushes the left locking block 312, causing it to move inward, compress the first return spring 313, and unlock. Simultaneously, the right locking component 32 is unlocked via the linkage 5. The right unlocking component 42 is a symmetrically arranged right button 421. The button-type unlocking is simple, intuitive, and provides a clear tactile feedback. In specific operation, the user can press the left button 411 or the right button 421 with their index finger, and then use their middle, ring, and little fingers to lift the support rod 23 to rotate the leg support frame 2. When rotated to the desired position, releasing the left button 411 or the right button 421 allows the left locking component 31 and the right locking component 32 to re-engage and lock under the reset action of the first and second return springs 313 and 323. Of course, the user can also unlock by pressing both the left button 411 and the right button 421 simultaneously.
[0042] like Figures 2 to 7 As shown, to ensure the stability of the trajectories of the left linkage 54 and right linkage 55 during movement and to prevent deviation, a laterally extending left guide groove 58 is provided on the left linkage 54. A left guide post 13 is fixedly provided on the seat part 1, and the left guide post 13 passes through the left guide groove 58. Similarly, a right guide groove 59 is provided on the right linkage 55, and a right guide post 14 passes through it on the seat part 1. Therefore, the movement paths of the left and right linkages 54 and 55 are precisely constrained and guided, so that they can only move in a predetermined direction, avoiding jamming.
[0043] like Figure 10 As shown, this embodiment also provides a stroller, including a frame 200, on which the aforementioned seating device 100 is connected. A backrest 6 is also connected to the rear side of the seat 1, forming a complete child seating space. With the stroller using the seating device 100 of this embodiment, parents can easily adjust the angle of the leg support frame 2 with one hand, greatly improving the convenience and efficiency of operation and enhancing the product's market competitiveness.
[0044] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
