Description

Technical Field

[0001] This disclosure relates to children's vehicles, and more specifically, to backrest limiting components for children's vehicles. Background Technology

[0002] To accommodate children's different needs when sitting or lying in a stroller, the angle of the seat back often needs to be adjusted during use. However, existing stroller seats are inconvenient to adjust when adjusting the seat back angle, especially since the seat back tends to tilt forward beyond the frame and cannot be stopped, thus posing a safety hazard.

[0003] Therefore, it is necessary to develop a backrest limiting device for children's strollers that can avoid the aforementioned problems existing in the prior art. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of this disclosure is to provide a backrest limiting component and a child stroller, wherein when the user adjusts the backrest forward, the backrest limiting component can limit the backrest to prevent it from exceeding the frame body when the seat back is tilted forward, thereby making the child stroller safer.

[0005] As embodied and summarized herein, in order to achieve these and other advantages and for the purposes of this disclosure, a backrest limiting assembly for a stroller is provided for limiting the adjustment position of the stroller's backrest. The backrest limiting assembly is mounted on the stroller's frame and includes two side guards located on the left and right sides of the backrest limiting assembly, a top guard located on the upper side of the backrest limiting assembly, and a backrest frame located on the rear side of the backrest limiting assembly, wherein the top guard is pivotally connected to the side guards and... The backrest is connected to the vehicle frame via an upper pivot and a lower pivot, respectively, so that the side guard, the top guard, the backrest, and the vehicle frame form a four-bar linkage. The backrest has two sides located on the left and right sides, and at least one side overlaps vertically with the side guard on the corresponding side, so that when the side of the backrest is pivoted forward around the lower pivot to a preset position, it will be blocked by the part of the side guard that is pivoted to the vehicle frame.

[0006] In one embodiment, each of the side guards is elongated and has a first end and a second end, the first end being pivotally connected to the frame via the upper pivot, and the second end being pivotally connected to the top guard.

[0007] In one embodiment, each of the side guards is a long strip of plate, and the plate has a hollow structure.

[0008] In one embodiment, both sides of the backrest are elongated, and the lower end of each side is pivotally connected to the frame via the lower pivot.

[0009] In one embodiment, the backrest frame further has an upper portion that connects the two sides together, and the top guard is pivotally connected to the upper portion of the backrest frame.

[0010] In one embodiment, the top guard is a plate-shaped piece with a hollow structure and has an upper part and a lower part, the side guard is pivotally connected to the upper part of the top guard, and the backrest is pivotally connected to the lower part of the top guard.

[0011] In one embodiment, each side of the backrest has a clearance bend at a position corresponding to the upper pivot, so that the backrest is not blocked by the side guards before pivoting forward to the preset position.

[0012] In one embodiment, the avoidance bend is formed by bending or recessing each side of the backrest at a position corresponding to the upper pivot.

[0013] In one embodiment, the frame includes a rider located at the upper part of the frame, and the backrest limiting assembly is mounted on the rider.

[0014] In one embodiment, the frame includes a rear frame located at the lower part of the frame, and a center post is fixed on the rear frame, such that the backrest limiting assembly can be mounted on the center post.

[0015] In another embodiment, this disclosure proposes a stroller that includes the backrest limiting component as described above.

[0016] The beneficial effect of this disclosure is that the backrest limiting component of the child stroller disclosed herein can limit the backrest of the seat, preventing it from exceeding the frame body when the backrest is tilted forward, thus making the child stroller safer.

[0017] The foregoing and other objects, features, aspects and advantages of this disclosure will become more apparent from the following detailed description of the disclosure taken in conjunction with the accompanying drawings. Attached Figure Description

[0044] In the following, exemplary embodiments will be described in detail with reference to the accompanying drawings. Although this disclosure is open to various modifications and alternatives, specific embodiments thereof are shown by way of example in the drawings. However, this disclosure should not be construed as limiting itself to the embodiments set forth herein, but rather, this disclosure is intended to cover all modifications, equivalents, and alternatives that fall within the spirit and scope of the embodiments.

[0045] Existing children's vehicles generally include a frame and a seat, the seat including a backrest, which is generally fixedly or adjustablely pivoted to the frame.

[0046] In the stroller 1 according to this disclosure, the seat backrest (not shown) is mounted on the frame via a backrest limiting assembly 10. The backrest limiting assembly 10 not only supports the backrest but also limits its adjustment position. In one embodiment, the frame includes a handlebar 20 located at the upper part of the frame for pushing and pulling the stroller 1, and the backrest limiting assembly 10 is mounted on the handlebar 20. In another embodiment, the frame includes a rear frame 40 located at the lower part of the frame, with a rear wheel mounted on the rear frame 40 and a center post 30 fixed thereon. The center post 30 can be fixed in a suitable position on the rear frame 40 such that the backrest limiting assembly 10 can be mounted on the center post 30, such as... Figure 1 and Figure 3 Ideally, this is particularly applicable to children's vehicles where the rider 20 can be rotated forward and backward. In the following description, this disclosure will be illustrated using the example of the backrest limiting assembly 10 mounted on the center pole 30, but it should be understood that this disclosure is not limited thereto. Furthermore, for ease of showing the construction of the children's vehicle 1, the accompanying drawings of this disclosure only show the skeletal structure of the children's vehicle 1 and its backrest limiting assembly 10, omitting accessories such as the seat and sunshade.

[0047] It should be noted that, for ease of description with reference to the accompanying drawings, this disclosure specifically refers to the forward direction of the stroller 1 as "front," the backward direction of the stroller 1 as "rear," and the two sides of the stroller 1 in the lateral direction as "left and right sides." However, it should be clearly understood that the scope of this disclosure is not limited to any particular direction described herein.

[0048] like Figures 1 to 4 As shown, the backrest limiting assembly 10 includes: two side guards 11 located on both sides of the backrest limiting assembly 10; a top guard 12 located on the upper side of the backrest limiting assembly 10; and a backrest frame 13 located on the rear side of the backrest limiting assembly 10.

[0049] The top guard 12 is pivotally connected between the side guards 11 and the backrest 13. The side guards 11 and the backrest 13 are pivotally connected to the central upright 30 via upper pivot O1 and lower pivot O2, respectively, so that the side guards 11, top guard 12, backrest 13, and central upright 30 constitute a four-bar linkage. Figure 2Best viewed. In this configuration, the central arm 30 corresponds to the frame (i.e., the fixed arm) in a four-bar linkage; the side guards 11 and backrest 13 correspond to the connecting rods (i.e., the rods connected to the frame) in the four-bar linkage; and the top guard 12 corresponds to the connecting link (i.e., the rod not connected to the frame but connecting two connecting rods) in the four-bar linkage. The side guards 11, top guard 12, and backrest 13, as movable components in the four-bar linkage, undergo rocker motion relative to the central arm 30. For example... Figure 3 As shown, when the backrest 13 has two sides 131 located on the left and right sides and at least one side 131 and the corresponding side guard 11 overlap vertically, the side guard 11, the top guard 12, the backrest 13 and the central upright 30 actually constitute a planar four-bar linkage.

[0050] The limiting principle of the back-mounted limiting component 10 according to this disclosure will now be described.

[0051] When the backrest limiting assembly 10, as described above, pivots forward relative to the central pole 30, the backrest frame 13 also pivots forward and approaches the side guard frame 11. Since at least one side 131 of the backrest frame 13 and the corresponding side guard frame 11 overlap vertically, when the backrest frame 13 pivots forward to a preset position, this side 131 of the backrest frame 13 will be blocked by the part of the side guard frame 11 that is pivotally connected to the central pole 30 and cannot continue to pivot forward. Figure 4 and Figure 5 As can be seen, the entire backrest limiting assembly 10 is unable to pivot forward any further. In this way, the backrest supported by the backrest limiting assembly 10 will not tilt too far forward and exceed the main body of the frame, thus realizing the backrest limiting function.

[0052] The preset position refers to the extreme position of the backrest 13 when it pivots forward around the lower pivot O2, which can be set according to actual needs. In addition, the preset position that the backrest 13 can reach when it pivots forward can be adjusted by changing the lengths of the side guards 11, the top guards 12 and the backrest 13, as well as the distance between the upper pivot O1 and the lower pivot O2.

[0053] Next, various embodiments of the back-stopping component 10 according to this disclosure will be described.

[0054] The side guards 11 protect children sitting on the seat from both sides. Preferably, the side guards 11 are elongated and have a first end 111 and a second end 112. The first end 111 is pivotally connected to the central support 30 via an upper pivot O1, and the second end 112 is pivotally connected to the top guard 12. For example, the side guards 11 can be rod-shaped or, as shown in the image, can be... Figure 1 and Figure 2 The long, strip-shaped piece shown can have a perforated structure, which not only reduces weight but also increases breathability.

[0055] Of course, the side guard 11 can also take other shapes such as square or triangular as needed, as long as it can be pivotally connected between the central upright 30 and the top guard plate 12. Moreover, the side guard 11 can be pivotally connected to the central upright 30 and the top guard plate 12 at other parts other than its ends.

[0056] The two sides 131 of the backrest 13 can also be elongated, such as in the form of a tube as shown in the figure. The lower end 1311 of each side 131 is pivotally connected to the central upright 30 via a lower pivot O2, which is located below the upper pivot O1. Similar to the side guards 11, the two sides 131 of the backrest 13 can also take other shapes such as square or triangular as needed, as long as they can be pivotally connected between the central upright 30 and the top guard plate 12. Moreover, the backrest 13 can be pivotally connected to the central upright 30 and the top guard plate 12 at locations other than the ends of the sides 131.

[0057] In the preferred embodiment shown in the figure, the backrest 13 also has an upper portion 132 that connects the two sides 131 together, and the top guard 12 can be pivotally connected to the upper portion 132 of the backrest 13. Of course, the backrest 13 may also not have an upper portion, in which case the upper ends of the two sides 131 are pivotally connected to the top guard 12 respectively.

[0058] Furthermore, to ensure that the backrest 13 does not interfere with the side guardrail 11 before pivoting forward to a preset position, each side 131 of the backrest 13 has a relief bend 1312 formed at a position corresponding to the upper pivot O1, such as... Figure 1 and Figure 2 Best visible. The avoidance bend 1312 can be formed by bending or recessing the portion of each side 131 of the backrest 13 at the position corresponding to the upper pivot O1. Specifically, the avoidance bend 1312 creates an avoidance space at the portion of each side 131 of the backrest 13 at the position corresponding to the upper pivot O1, and the first end 111 of the side guard 11 gradually enters the avoidance space before the backrest 13 pivots forward to a preset position (e.g., ...). Figure 5 (Best visible) until the side guard 11 reaches the preset position without obstructing the side 131 of the backrest 13 from continuing to pivot forward.

[0059] The top guardrail 12 is pivotally connected between the side guardrail 11 and the backrest 13. For example... Figure 1 and Figure 2 As shown, the top guard 12 has an upper part 122 and a lower part 121, wherein the upper part 122 is pivotally connected to the second end 112 of the side guard 11, and the lower part 121 is pivotally connected to the backrest 13. Of course, the top guard 12 may also be pivotally connected to the side guard 11 and the backrest 13 at other locations other than the upper part 122 and the lower part 121.

[0060] Additionally, as shown in the figure, the top support frame 12 is a sheet-like component, and this sheet-like component can also adopt a perforated structure, thereby reducing weight and increasing breathability. Of course, in other embodiments, the top support frame 12 can also adopt, for example, a rectangular frame structure.
