Abstract
Description
Technical Field
[0001] The present disclosure relates to a frame folding (retracting) fixing device and a baby carrier including the frame folding fixing device.
Background Art
[0002] A baby carrier can reduce the fatigue caused by holding a baby for a long time and improve the comfort of people's lives. The main structure of a baby carrier usually includes a handle (grip) portion and a front leg portion. In order to conveniently store and carry the baby carrier when it is not in use temporarily, usually, the handle portion and the front leg portion can be relatively folded to reduce the occupied volume of the baby carrier.
[0003] Specifically, referring to FIG. 10, which is a schematic diagram showing a frame folding fixing hook of the related art, a joint 30' is arranged between a handle 10' and a front leg 20'. Due to the arrangement of the joint 30', the handle 10' and the front leg 20' can be folded or deployed (extended) relative to each other, so that the baby carrier can be conveniently stored, carried, and redeployed for use when it is not in use temporarily.
[0004] In order to lock the folded state of the baby carrier and prevent it from being undesirably opened (deployed), according to the related art shown in FIG. 10, a frame folding fixing hook 40' is provided. One end of the frame folding fixing hook 40' is fixedly arranged on, for example, the front leg 30', and the other end is provided in a hook shape. When the handle 10' and the front leg 20' are in the folded state, the other end of the frame folding fixing hook 40' is hooked on, for example, the handle 10' to lock the folded state of the baby carrier. When it is necessary to deploy the handle 10' and the front leg 20' relative to each other again, it is necessary to manually release the other end of the hook of the frame folding fixing hook 40' to release the folded locked state of the baby carrier (that is, unlock the lock).
[0005] However, the above-mentioned frame folding fixing hook 40' in the related art has the following problems. The frame folding fixing hook 40' exposed outside the frame has poor aesthetics and needs to be manufactured separately and then connected to the baby carrier, so the manufacturing process and manufacturing cost increase. Also, when the baby carrier is in the deployed state, the exposed frame folding fixing hook 40' naturally hangs down on the handle 10' or the front leg 20', making it easy for the user to accidentally get injured and reducing the safety of using the baby carrier.
Summary of the Invention

Best Mode for Carrying Out the Invention
[0037] Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings. The present disclosure is susceptible to various changes and alternative forms, but specific embodiments are shown by way of example in the accompanying drawings. However, the present disclosure should not be construed as limited to the embodiments described herein. Instead, the present disclosure is directed to all modifications, equivalents, and alternatives falling within the spirit and scope of the embodiments.
[0038] The frame folding fixing device of the present disclosure can be used in combination with various forms of baby carriers, such as baby strollers, children's tricycles, children's bicycles, children's balance bikes, fan handlebar bikes, etc., to lock the folded states of various baby carriers. For convenience of explanation, in the following detailed description, mainly an example of a baby carrier in the form of a baby stroller will be referred to.
[0039] Hereinafter, with reference to the accompanying drawings, the frame folding and fixing device 40 in the present disclosure and the baby carrier 1 including the frame folding and fixing device 40 will be described in detail.
[0040] FIG. 1 is a schematic view showing the baby carrier 1 in the present disclosure, and the handle 10 is in a deployed state with respect to the front leg 20. According to the embodiment shown in this figure, the baby carrier 1 includes a handle 10, a front leg 20, and a joint 30 between the handle 10 and the front leg 20. Further, as shown in FIG. 1, a handle fastener 12 is provided on the handle 10, and a front leg fastener 22 is provided on the front leg 20. And, as shown in FIG. 2, it is an exploded schematic view showing the specific structure of the joint 30 of the baby carrier 1 according to the present disclosure, and the joint 30 includes a first housing 32, a second housing 34, and a close cover 36 for covering the first housing 32 and the second housing 34. In the illustrated embodiment, the front leg fastener 22 is provided on the first housing 32, and the handle fastener 12 is provided on the second housing 34. Further, a frame deployment lock member 50 and an elastic member 60 are also provided on the joint 30.
[0041] Next, with reference to FIGS. 3 and 4, the frame folding and fixing device 40 in the present disclosure will be described. FIG. 3 is a schematic diagram showing the structure of the frame folding and fixing device 40 in the present disclosure. The frame folding and fixing device 40 includes a first locking device 42 disposed at the joint 30 and provided on the front leg 20 of the frame, and a second locking device 44 provided on the handle 10 of the frame. Specifically, the first locking device 42 is disposed in the first housing 32 of the joint 30 connected to the front leg fastener 22, and the second locking device 44 is disposed in the second housing 34 of the joint 30 connected to the handle fastener 12. When the front leg 20 of the frame is folded with respect to the handle 10 of the frame, the first locking device 42 and the second locking device 44 can rotate towards each other and then lock. When the front leg 20 of the frame is deployed with respect to the handle 10 of the frame, the first locking device 42 and the second locking device 44 are unlocked and rotate away from each other.
[0042] Next, the specific operations of the first locking device 42 and the second locking device 44 while the front leg 20 is folded with respect to the handle 10 will be described in detail with reference to FIGS. 4 to 6. FIG. 4 is a schematic diagram showing the baby carrier 1 in a state where the handle 10 in the present disclosure is not folded with respect to the front leg 20. FIG. 5 is a schematic diagram showing the baby carrier 1 in a state where the handle 10 in the present disclosure is in a half-folded state with respect to the front leg 20. FIG. 6 is a schematic diagram showing the baby carrier 1 in a state where the handle 10 in the present disclosure is completely folded with respect to the front leg 20.
[0043] When the handle 10 is in the deployed state with respect to the front leg 20, according to the illustrated embodiment, referring to FIG. 4A which is an enlarged view showing the details of portion A in FIG. 4, the first locking device 42 includes a base 421 and a boss 422. The boss 422 is the base 421 and is provided on the side surface of the base 421. The second locking device 44 includes an arc rib 441 and a locking projection 442. The arc rib 441 is fitted onto the base 421 of the first locking device 42 and can slide on the base 421. When the handle 10 in FIG. 4 is in the deployed state with respect to the front leg 20, the boss 422 of the first locking device 42 is separated from the locking projection 442 of the second locking device 44 in the circumferential direction. Also, when the handle 10 in FIG. 5 is in the semi-folded state with respect to the front leg 20, as shown in FIG. 5A which is an enlarged view showing the details of portion A in FIG. 5, the arc rib 441 slides on the base 421 in the clockwise direction indicated by the arrow shown in this figure, and the locking projection 442 gradually approaches the boss 422 in the circumferential direction. Further, when the handle 10 in FIG. 6 is in the completely folded state with respect to the front leg 20, as shown in FIG. 6A which is an enlarged view showing the details of portion A in FIG. 6, the arc rib 441 drives the locking projection 442 to pass through the boss 422 and then continues to slide in the clockwise direction so as to be locked with the boss 422. Therefore, when the handle 10 and the front leg 20 are in the completely folded state, the locking between the locking projection 442 and the boss 422 locks the above-mentioned completely folded state, and it is avoided that the completely folded state is undesirably deployed (opened).
[0044] Figures 7 and 7A show the case where the baby carrier 1 needs to be redeployed for continuous use. FIG. 7 is a schematic view showing the baby carrier 1 in a state where the handle 10 in the present disclosure is redeployed with respect to the front leg 20, and FIG. 7A is an enlarged view showing the details of part A of FIG. 7. At this time, the user can forcefully lift the handle 10 upward so that the arc rib 441 of the second locking device 44 slides in the counterclockwise direction indicated by the arrow in FIG. 7A, and the locking protrusion 442 correspondingly passes through the boss 422 in the counterclockwise direction. Then, the lock in the fully folded state is released or unlocked, and the user can conveniently deploy the handle 10 with respect to the front leg 20.
[0045] The handle 10 needs to rotate at a specific angle when the handle is fully folded with respect to the front leg 20. In an embodiment, the handle needs to rotate about 90 to 180 degrees, preferably about 100 to 120 degrees, more preferably about 103 to 110 degrees. Therefore, according to the preferred embodiment shown in this figure, the arc rib 441 extends an arc length corresponding to a specific angle at which the handle 10 needs to rotate relative to the front leg 20 when being fully folded, and satisfies the moving distance of the handle 10 with respect to the front leg 20 during being fully folded. For example, the arc length of the arc rib can be in the range of about one-fourth to about one-half of the circumferential length.
[0046] Next, with reference to FIGS. 8 and 9, the frame folding fixing device 40 according to another embodiment of the present disclosure will be described in detail. FIGS. 8 and 9 are schematic views showing the frame folding fixing device 40 according to another embodiment of the present disclosure. FIG. 8 shows that the frame folding fixing device 40 is in an unlocked state, and FIG. 9 shows that the frame folding fixing device 40 is in a locked state. The differences between the frame folding fixing device 40 according to this embodiment and the first embodiment will be mainly described, and the same content will be omitted.
[0047] The first locking device 42 of the frame folding fixing device 40 includes a boss 422 and a stopper 423, and the boss 422 and the stopper 423 are arranged opposite to each other. The second locking device 44 of the frame folding fixing device 40 includes a locking protrusion 442 and an arc groove 443. The locking protrusion 442 is arranged in the arc groove 443 and protrudes toward the inside of the arc groove 443. Further, the boss 422 and the stopper 423 of the first locking device 42 described above are fitted into the arc groove 443. From the above structure, in the unlocked state shown in FIG. 8, the locking protrusion 442 is separated from the boss 422 in the circumferential direction. While the handle 10 is gradually folded with respect to the front leg 20, the locking protrusion 442 slides in the clockwise direction indicated by the arrow in FIG. 8, and the arc groove 443 also slides in the clockwise direction accordingly. The boss 422 and the locking protrusion 442 gradually approach each other in the circumferential direction. After the handle 10 is completely folded with respect to the front leg 20, the locking protrusion 442 passes over the boss 422 and is locked with the boss 422. The stopper 423 arranged opposite to the boss 422 can prevent the locking protrusion 442 from slipping off the lock with the boss 422. Thereby, the complete folded state of the baby carrier 1 can be ensured, and it is possible to avoid being undesirably deployed. When it is necessary to deploy again for continuous use of the baby carrier, the user can forcibly lift the handle so that the locking protrusion 442 slides in the counterclockwise direction to release the lock with the boss 442, thereby releasing the folded state of the baby carrier.
[0048] Similarly, the arc length of the arc groove 443 also corresponds to a specific angle at which the handle 10 needs to rotate relative to the front leg 20 when being completely folded, and satisfies the moving distance of the handle 10 with respect to the front leg 20 during the process of being completely folded.
[0049] The frame folding and fixing device 40 in the present disclosure is hidden in the joint 30, improving the overall aesthetics of the baby carrier 1. The hidden frame folding and fixing device 40 avoids the security risks caused by the exposed arrangement of the frame folding and fixing hook in the related art, and greatly improves the use safety of the baby carrier. The frame folding and fixing device 40 in the present disclosure has a simple structure and does not require additional processing steps and assembly steps, thereby reducing the manufacturing cost. Furthermore, the frame folding and fixing device 40 in the present disclosure also has the beneficial effect of being easy to operate.
[0050] Since the features of the present can be embodied in various forms without departing from the features of the present disclosure, the above-described embodiments are not particularly limited to the above details without special notice, and should be understood to be broadly construed as falling within the scope defined by the appended claims. Therefore, all modifications and changes corresponding to the scope and limitations described in the claims, or equivalent solutions to such scope and limitations, shall be covered by the appended claims.
