Detailed Description
Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings. While the disclosure is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings. However, the disclosure should not be construed as limited to the embodiments set forth herein, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the embodiments.
Unless otherwise defined, all terms including technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the stroller in this disclosure is generally designated by the reference numeral "1". In addition, for convenience of description, the direction in which the child vehicle is heading is defined herein as "forward" and the direction in which the child vehicle is backing is defined herein as "rearward".
The child car 1 includes a handlebar frame 11 located at an upper portion of the child car 1 and a rear frame 12 and a front frame 13 located at a lower portion of the child car 1 and arranged in the front-rear direction, the handlebar frame 11, the rear frame 12 and the front frame 13 being pivotally connected together relative to each other so that the handlebar frame 11, the rear frame 12 and the front frame 13 can be pivoted to each other to fold the child car 1 together when necessary, as shown in fig. 4 to 6, so as to store the child car 1 with a minimum space. The rear frame 12 is mounted with the rear wheels 121, and the front frame 13 is mounted with the front wheels 131.
In the embodiment shown in the figures, the ends of the handlebar 11 and the front frame 13 are pivoted together, and the rear frame 12 is pivoted to the handlebar 11. However, the present disclosure is not limited thereto, and the hand frame 11, the rear frame 12, and the front frame 13 may take other forms to be pivoted together, for example, the hand frame 11, the rear frame 12, and the front frame 13 may be pivoted to the same pivot.
When the stroller 1 is folded, the handlebar 11, the rear frame 12 and the front frame 13 are pivoted relative to each other to be folded together, but since there are accessories (not shown) such as seats and tarpaulins on the stroller 1, these accessories generate a certain elastic force after the stroller 1 is folded, so that the stroller 1 is bounced off and cannot maintain a compact folded state once the external force applied when the stroller 1 is folded is removed. Therefore, the present disclosure provides a folding mechanism.
The folding mechanism according to the present disclosure includes a folding protrusion 21 on the handle frame 11 and a folding hook 22 on the rear frame 12. When the child stroller 1 is folded, the handlebar 11 and the rear frame 12 are pivoted to approach each other so that the folding projection 21 can be snapped into the folding hook 22, thereby holding the child stroller 1 in the folded state as shown in fig. 5 and 6. The folding projection 21 and the folding hook 22 may be respectively disposed at any positions on the handle frame 11 and the rear frame 12, as long as the positions of the two correspond to each other. Preferably, the folding projection 21 and the folding hook 22 are positioned on the handlebar 11 and the rear frame 12, respectively, at positions away from the pivot joint, so that the child car 1 can be kept in a compact folded state after the folding projection 21 and the folding hook 22 are engaged.
In the embodiment shown in fig. 1 and 4, the converging protrusion 21 has a cylindrical shape. It should be understood that the converging protrusion 21 may take other shapes such as a prism, a truncated cone, etc.
Fig. 3 shows the snap hooks 22 in detail. The folding hook 22 has a connecting portion 221 connected to the rear frame 12 and an engaging recess 222 into which the folding projection 21 is engaged. The connecting portion 221 may be located at one end of the retracting hook 22. Preferably, the folding hooks 22 are pivotally connected to the rear frame 12 via the connecting portion 221 so as to adjust the folding hooks 22 to be more easily engaged with the folding protrusions 21. The engaging recess 222 may be formed by a side surface of the retracting hook 22 being recessed downward, or may be formed by providing an annular wall on a side surface of the retracting hook 22. The engaging recess 222 may have a square shape as shown in fig. 3, or may have another shape such as a circular shape or a triangular shape.
In order to satisfy various requirements, as shown in fig. 3, the catching recess 222 may include a first catching recess 222a distant from the connection portion 221 and a second catching recess 222b close to the connection portion 221, the first catching recess 222a and the second catching recess 222b being spaced apart by a predetermined distance.
As shown in fig. 5, when the folding projection 21 is engaged with the first engaging recess 222a, since the distance between the first engaging recess 222a and the connecting portion 221 is relatively longer than the distance between the second engaging recess 222b and the connecting portion 221, the distance between the folding projection 21 engaged with the first engaging recess 222a and the connecting portion 221 is also relatively longer, which makes the included angle between the handlebar 11 fixed with the folding projection 21 and the rear frame 12 fixed with the connecting portion 221 larger, and at this time, the folded stroller 1 can keep a standing posture.
As shown in fig. 6, when the folding projection 21 is engaged with the second engaging recess 222b, since the distance between the second engaging recess 222b and the connecting portion 221 is relatively short, the distance between the folding projection 21 engaged with the second engaging recess 222b and the connecting portion 221 is also short, which makes the included angle between the handle frame 11 and the rear frame 12 small, and at this time, the folded child car 1 will be more compact, but this compact state is favorable for storing the child car 1 in a smaller space, for example, reducing the packaging volume of the child car 1. Further, in order to make the child car 1 more compactly folded, the front wheels 131 may be arranged to be detachable from the front frame 13 so that the front frame 13 may be closer to the rear frame 12.
In addition, in order to space the first engaging recess 222a and the second engaging recess 222b by a predetermined distance while preventing the folded protrusion 21 from unintentionally switching the position between the first engaging recess 222a and the second engaging recess 222b, in one embodiment, a spacer 223 is provided therebetween. The spacers 223 may be one or more spacer ribs or spacer blocks. As shown in fig. 3, a barrier rib 223 is formed in a middle region of the engaging recess 222 in the lateral direction X for separating the first engaging recess 222a from the second engaging recess 222 b. Of course, the plurality of barrier ribs 223 may be formed in the middle region of the engagement recess 222 in the lateral direction X in sequence so that the first engagement recess 222a and the second engagement recess 222b are spaced apart by a predetermined distance. In a preferred embodiment, one or more reinforcing ribs 224 (two in fig. 3) extend from the barrier rib 223 in the longitudinal direction Y in the second engaging recess 222 b. The reinforcing ribs 224 not only have the function of increasing the strength of the folding hook 22, but also further limit the position of the folding protrusion 21 in the second engaging recess 222b, so that when the folding protrusion 21 is engaged with the second engaging recess 222b, the distance between the folding protrusion 21 engaged in the second engaging recess 222b and the connecting portion 221 is closer, thereby resulting in a smaller included angle between the handle frame 11 and the rear frame 12, and the folded stroller 1 is more compact. In another embodiment, in the first catching recess 222a, one or more reinforcing ribs 224 extend from the barrier rib 223 in the longitudinal direction Y.
In another embodiment, in order to space the first catching recess 222a and the second catching recess 222b by a predetermined distance, an area of the folding hook 22 between the two catching recesses may not be formed to be recessed downward, so that the area of the folding hook 22 not recessed downward is naturally formed as the spacer 223.
It should be understood that the folded-back protrusion 21 may be switched from the first catching recess 222a to the second catching recess 222b or from the second catching recess 222b to the first catching recess 222a under the user's intention. This switching may be performed by sliding the collecting projection 21 from one engaging recess to the other along the partition 223, or may be performed by disengaging the collecting projection 21 from the collecting hook 22 and then engaging the collecting hook with the other engaging recess again. The two switching modes can be selected according to the actual use needs of users.
The exemplary embodiments of the invention presented in this application should not be construed as limiting the application of the appended claims. The verb "to comprise" is used in this patent application as an open limitation that does not exclude the presence of unrecited features. The features recited in the dependent claims may be freely combined with each other, unless otherwise specified. The novel features believed characteristic of the invention are set forth with particularity in the appended claims.
As the present features may be embodied in several forms without departing from the characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims.
