Description

Technical Field

[0001] This disclosure relates to children's products, and more specifically, to the frames of children's vehicles and children's vehicles using the frames. Background Technology

[0002] Strollers are typically used to take children outdoors. With technological advancements, strollers have been designed with certain parts that can move relative to each other, allowing for some degree of deformation and enabling them to fold up, resulting in a more compact structure. However, existing strollers, designed for storage, contain numerous components, increasing their weight and making it difficult to maintain a folded state. Some even require a separate component to keep the stroller folded, all of which contribute to an overly complex structure.

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

[0004] The purpose of this disclosure is to provide a frame for a children's vehicle and a children's vehicle using the frame, which is structurally simpler and easier for users to use than existing children's vehicles.

[0005] As embodied and summarized herein, in order to achieve these and other advantages and for the purposes of this disclosure, a frame for a children's bicycle is proposed, the frame comprising: a handlebar located at the upper part of the frame; a front frame located at the lower part of the frame, the upper end of the front frame and the lower end of the handlebar being connected together via a hinge, wherein the hinge is pivotable or locked pivotable, wherein when the hinge is pivotable, the handlebar and the front frame are pivotable relative to each other by means of the hinge, and when the hinge is locked pivotable, the handlebar and the front frame are not pivotable relative to each other; a rear frame located at the lower part of the frame and behind the front frame, the upper end of the rear frame being pivotally connected to a first hinge on the handlebar; a support frame, the front end of which is pivotally connected to a second hinge on the front frame, and the rear end of which is pivotally connected to a third hinge on the rear frame.

[0007] In one embodiment, the second hinge is positioned near the upper end of the front frame.

[0008] In one embodiment, the hinge includes a pivotable body and two sleeves connected to the body, the two sleeves being pivotable relative to each other by means of the body, the upper end of the front frame and the lower end of the rider frame respectively inserted into the two sleeves.

[0009] In one embodiment, the first hinge and the second hinge are respectively positioned on the two sleeves.

[0010] In one embodiment, the upper end of the rider frame is provided with a rider, the lower end of the front frame is provided with a front wheel, and the lower end of the rear frame is provided with a rear wheel.

[0011] In one embodiment, the frame's hinges allow a seat to be detachably mounted thereon.

[0012] In one embodiment, the seat itself is foldable, and the seat is pivotable with the frame between a use position and a folded position by means of the hinge, wherein the seat can be held in the use position or the folded position when the hinge is locked during pivoting.

[0013] In one embodiment, the frame further includes a connector disposed at the hinge, the connector allowing a basket to be detachably mounted thereon.

[0014] In another embodiment, this disclosure proposes a children's stroller that uses the frame as described above.

[0055] 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.

[0056] It is understood that although terms such as "first" and "second" may be used herein to describe various elements, these elements are not limited by these terms. These terms are generally used only to distinguish one element from another. Furthermore, terms specifically defined in consideration of the construction and operation of the embodiments are used only to describe the embodiments and not to limit the scope of the embodiments.

[0057] In addition, relational terms such as “upper end” and “lower end”, “front end” and “back end” are used only to distinguish one object or element from another, and are not required to require or involve any physical or logical relationship or order between these objects or elements.

[0058] This disclosure will now be described in detail with reference to the accompanying drawings.

[0059] like Figures 1-3As shown, the frame of the children's bicycle according to this disclosure is generally indicated by reference numeral "1" and consists of four frame parts, specifically including: a handlebar frame 10 located at the upper part of the frame 1; a front frame 20 located at the lower part of the frame 1, the upper end 21 of the front frame 20 and the lower end 11 of the handlebar frame 10 being connected together via a self-locking hinge 100; a rear frame 30 located at the lower part of the frame 1 and behind the front frame 20, the upper end 31 of the rear frame 30 being pivotally connected to a first hinge 200 on the handlebar frame 10; a support frame 40 connecting the front frame 20 and the rear frame 30, the front end 41 of the support frame 40 being pivotally connected to a second hinge 300 on the front frame 20, and the rear end 42 of the support frame 40 being pivotally connected to a third hinge 400 on the rear frame 30.

[0060] The handlebar frame 10 is the upper frame of the frame 1, mainly used to provide a point of leverage for the user to move the stroller. In one embodiment, a handlebar 120 can be mounted on the upper end 12 of the handlebar frame 10.

[0061] The front frame 20 and the rear frame 30 together form the lower frame of the frame 1, which is connected to wheels to facilitate the user's movement of the stroller. Specifically, the lower end 22 of the front frame 20 is provided with a front wheel 220, and the lower end 32 of the rear frame 30 is provided with a rear wheel 320. Although in the embodiment shown in the accompanying drawings, there are two front wheels 220 and two rear wheels 320, this disclosure is not limited to this, and there may also be only one front wheel 220.

[0062] The support frame 40 is connected between the front frame 20 and the rear frame 30 to maintain a certain angle between the front frame 20 and the rear frame 30, so that the lower frame formed by the front frame 20 and the rear frame 30 is in a stable support state, so as to effectively support the child equipment placed on the frame 1 and the child riding in the child equipment.

[0063] It is particularly noteworthy that the frame 1 of the children's bicycle according to this disclosure employs four hinge devices to connect the four frame parts, including hinge 100, first hinge 200, second hinge 300, and third hinge 400. With the aid of these four hinge devices, the four frame parts of the frame 1 effectively form a multi-bar linkage mechanism. Furthermore, since hinge 100 can pivot or lock pivot, when hinge 100 can pivot, the handlebar 10 and front frame 20 can pivot relative to each other via hinge 100, at which point the linkage mechanism forms a four-bar linkage; when hinge 100 is locked pivot, the handlebar 10 and front frame 20 cannot pivot relative to each other, at which point the linkage mechanism forms a three-bar linkage. With the aid of these four hinge devices, the frame 1 of the children's bicycle can be easily unfolded and folded, while being stably maintained in both unfolded and folded states.

[0064] The working principle of the four frame parts and four hinge devices of the frame 1 will be described in detail below.

[0065] When the frame 1 of the stroller is in the position as Figure 1 In the deployed state, hinge 100 is locked and pivoted. At this time, the frame 10 and front frame 20 cannot pivot relative to each other, so the frame 10 and front frame 20 can be considered as forming a single linkage. Thus, the linkage formed by the frame 10 and front frame 20, the linkage formed by the rear frame 30, and the linkage formed by the support frame 40 are connected together via the first hinge 200, the second hinge 300, and the third hinge 400, respectively, forming a three-bar linkage. Because this three-bar linkage forms a stable triangle, the frame 1 will be stably held in the deployed state.

[0066] When the frame 1 of the stroller is in the position as Figure 2 and Figure 3 In the folded state shown, hinge 100 is unlocked and can pivot. At this time, the frame 10 and front frame 20 can pivot relative to each other via hinge 100, so the frame 10 and front frame 20 can be considered as two links. Thus, the links formed by the frame 10, the front frame 20, the rear frame 30, and the support frame 40 are connected together via hinge 100, first hinge 200, second hinge 300, and third hinge 400, respectively, forming a four-bar linkage. Because this four-bar linkage can swing, the angle θ1 between the frame 10 and the front frame 20 decreases, and the angle θ2 between the rear frame 30 and the support frame 40 also decreases, thereby allowing the frame 1 to be folded together more compactly.

[0067] What is particularly advantageous is that, since the hinge 100 can be locked and pivoted, once the frame 1 is folded up, it is only necessary to lock and pivot the hinge 100 so that the rider frame 10 and the front frame 20 cannot pivot relative to each other, and the frame 1 can remain folded up without the need for a separate component to keep the bike folded up.

[0068] Preferably, the first hinge 200 can be positioned near the lower end 11 of the frame 10, and the second hinge 300 can be positioned near the upper end 21 of the front frame 20. This makes the lower part of the frame 1 more compact, and also reduces the space occupied by the frame 1 when folded.

[0069] in addition, Figures 1-3The diagram illustrates a connection between the upper end 21 of the front frame 20 and the lower end 11 of the rider frame 10 and the hinge 100. The hinge 100 includes a pivotable body 101 and two sleeves 102 connected to the body 101. The two sleeves 102 are pivotable relative to each other by means of the body 101, and the upper end 21 of the front frame 20 and the lower end 11 of the rider frame 10 are respectively inserted into the two sleeves 102. In this configuration, the first hinge 200 and the second hinge 300 can be positioned on the two sleeves 102, respectively.

[0070] However, this disclosure is not limited thereto. For example, the upper end 21 of the front frame 20 and the lower end 11 of the rider frame 10 may be directly fixed to the body 101 of the hinge 100 without passing through the sleeve 102, as long as it can be ensured that the rider frame 10 and the front frame 20 can pivot relative to each other by means of the hinge 100.

[0071] In order to expand the application range of the frame 1 of the children's vehicle, the frame 1 of the children's vehicle according to the present disclosure can carry a variety of children's products, including a seat 60 and a baby carrier 70.

[0072] In such Figure 4 In the embodiment shown, the hinge 100 of the frame 1 allows the seat 60 to be detachably mounted thereon.

[0073] In such Figure 5 and 6 In another embodiment shown, the frame 1 may further include a connector 50 disposed at the hinge 100, the connector 50 being detachably mounted on the basket 70, the connector 50 being able to better position the basket 70.

[0074] Preferably, the seat 60 itself is foldable, so that it can be folded down together with the frame 1. For example... Figure 7 and Figure 8 As shown, the folded seat 60 can pivot between the use position and the folded position along with the frame 1 via the hinge 100. Moreover, when the hinge 100 is locked during pivoting, the seat 60 can be held in either the use position or the folded position. Thus, when folding the frame 1, the seat 60 does not need to be removed from the frame 1; the seat 60 can be folded up along with the frame 1.

[0075] It should be noted that, in order to show the structure more clearly, Figure 4 , Figure 7 and Figure 8 The seats 60 shown are all seat frame structures, but it should be understood that the seat 60 described in this disclosure is an integral seat including the frame structure.

[0076] The foregoing embodiments and advantages are merely exemplary and should not be construed as limiting the scope of this disclosure. The description herein is intended to be illustrative and not to limit the scope of the claims. Various alternatives, modifications, and alterations will be apparent to those skilled in the art. The features, structures, methods, and other characteristics of the exemplary embodiments described herein can be combined in various ways to obtain other and / or alternative exemplary embodiments.

[0077] Since the features of this disclosure can be embodied in various forms without departing from the nature of this disclosure, it should also be understood that the above embodiments are not limited to any of the details described above, and unless otherwise stated, should be broadly interpreted as falling within the scope defined by the appended claims. Therefore, all modifications and alterations falling within the scope and limits of the claims or equivalents thereof should be covered by the appended claims.
