Description

Technical Field

[0001] The present invention relates to baby (infant) products, and more specifically, to a unlocking device and a stroller equipped with the unlocking device.

Background Art

[0002] A stroller is a means of transportation designed to provide convenience for infants' outdoor activities and has been widely used for a long time. Currently, some strollers include a frame, a frame folding mechanism, front wheels, rear wheels, and a wheel rotation direction mechanism. The frame folding mechanism is configured to fold the frame. In this way, when the stroller is not in use, the stroller can be folded into a smaller volume for easy carrying and storage. The wheel rotation direction mechanism is configured to lock and unlock the rotatable rear wheels. The wheel rotation direction mechanism unlocks the rear wheels so that the rear wheels can rotate freely. When reversing, the rear wheels can rotate at a specific angle to facilitate changing the direction of the stroller. After changing the direction, the wheel rotation direction mechanism can be used to lock the rear wheels and move the rear wheels forward by changing their positions. However, the above-described mechanisms occupy more space in the stroller, the operation is extremely inconvenient, the stroller looks bad, and the purchase intention of consumers may decrease.

Summary of the Invention

[0003] In order to solve the above problems, the present invention provides an unlocking device and a stroller equipped with the unlocking device.

[0004] According to an embodiment of the present invention, the unlocking device includes at least one operating member, a first unlocking module, and a second unlocking module. The at least one operating member is movably disposed on the frame, and the frame includes a first locking mechanism and a second locking mechanism. The first unlocking module is movably disposed on the frame and is connected to the first locking mechanism. The second unlocking module is movably disposed on the frame and is connected to the second locking mechanism. The at least one operating member moves to drive the first unlocking module to move to unlock the first locking mechanism, or drives the second unlocking module to move to unlock the second locking mechanism.

[0005] In another embodiment, the unlocking device may further include a selection member movably disposed on the frame. The selection member moves between a first position and a second position relative to the frame. When the selection member is disposed at the first position, the at least one operating member slides to drive the first unlocking module to move to unlock the first locking mechanism. When the selection member is disposed at the second position, the at least one operating member slides to drive the second unlocking module to move to unlock the second locking mechanism.

[0006] In another embodiment, the at least one operating member may include a first operating member and a second operating member. The first operating member slides to drive the first unlocking module to move to unlock the first locking mechanism, and the second operating member slides to drive the second unlocking module to move to unlock the second locking mechanism.

[0007] In another embodiment, the unlocking device may further include a holding mechanism disposed on at least one operating member. The holding mechanism holds the at least one operating member at the unlocking position when the at least one operating member slides to unlock one of the first locking mechanism and the second locking mechanism. The holding mechanism releases the at least one operating member when the at least one operating member is actuated from the unlocking position.

[0008] According to an embodiment of the present invention, a baby stroller includes a frame, a wheel socket, a first locking mechanism, a second locking mechanism, and the aforementioned unlocking device. The wheel socket is rotatably disposed on a leg of the frame. The first locking mechanism is disposed on the frame and configured to fold the frame. The second locking mechanism is disposed on the frame and configured to lock the wheel socket. The unlocking device is configured to unlock the first locking mechanism and the second locking mechanism.

[0009] As described above, the present invention uses at least one operating member to drive and move the first unlocking module to move so as to unlock the first locking mechanism, or to drive and move the second unlocking module to move so as to unlock the second locking mechanism. In an embodiment, the selection member may be movably disposed on the frame and may be movable between a first position and a second position with respect to the frame. When the selection member is disposed at the first position, the first locking mechanism corresponds to the operating member such that the operating member can drive and move the first unlocking module to slide so as to unlock the first locking mechanism. When the selection member is disposed at the second position, the second locking mechanism corresponds to the operating member such that the operating member can drive and move the second unlocking module to slide so as to unlock the second locking mechanism. Therefore, the present invention does not need to dispose two independent unlocking devices to unlock the first and second locking mechanisms. That is, the present invention can unlock two different locking mechanisms using a single unlocking device. Therefore, the manufacturing cost is reduced, and the unlocking device of the present invention occupies less space in the stroller and is easy and convenient to operate.

[0010] In another embodiment, the at least one operating member may include a first operating member and a second operating member configured to unlock the first locking mechanism and the second locking mechanism, respectively. In other words, the present invention may unlock two different locking mechanisms using two operating members.

[0011] In another embodiment, the present invention may hold the operating member at the unlocking position using a holding mechanism when the operating member slides to unlock the first locking mechanism and the second locking mechanism. Accordingly, the first locking mechanism and the second locking mechanism can be held in the unlocked state until the operating member is actuated from the unlocking position. For example, the second locking mechanism may be a wheel rotation direction mechanism, and the holding mechanism may hold the operating member at the unlocking position when the operating member slides to unlock the second locking mechanism. When the user presses the operating member to unlock the wheel rotation direction mechanism, the wheel rotation direction mechanism is held at the unlocking position so that the wheels can still rotate freely even if the user releases the operating member. Further, when the operating member is actuated from the unlocking position, the holding mechanism releases the operating member so that the operating member slides to lock the wheel rotation direction mechanism and then the wheels are locked.

[0012] These and other objects of the present invention will become apparent to those skilled in the art without doubt after reading the following detailed description of the preferred embodiments illustrated in the various figures and drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0041] Referring to FIGS. 1 to 3, the baby stroller 100 of the present invention includes a frame 2, a wheel socket 3, a first locking mechanism 4, a second locking mechanism 5, and an unlocking device 1. In this embodiment, the first locking mechanism 4 may be, without limitation, a frame folding mechanism, and the second locking mechanism 5 may be, without limitation, a wheel rotation direction mechanism. The frame 2 includes a handle 21, a front leg 22, and a rear leg 23. The front leg 22 and the rear leg 23 are legs of the frame 2, and each wheel socket is provided with a wheel. The first locking mechanism 4 is disposed on the frame 2 and configured to fold the frame 2. The first locking mechanism 4 is well known to those skilled in the art. Generally, the first locking mechanism 4 may include a wire and a locking member. One end of the wire is connected to the locking member, and the locking member is engaged between the handle 21 and the rear leg 23 of the frame 2. When the other end of the wire is pulled, the wire drives the locking member to release the engagement so that the frame 2 can be folded and the frame 2 is unlocked. Since the first locking mechanism 4 is well known to those skilled in the art, the figure only exemplifies the wire of the first locking mechanism 4.

[0042] In an exemplary embodiment, the first locking mechanism 4 and the second locking mechanism 5 can be, without limitation, one of the locking mechanisms for handle conversion, wheel braking, handle angle adjustment, frame folding, and wheel rocking lock, but their functions do not overlap with each other.

[0043] Referring to FIGS. 1 and 8, the wheel socket 3 is rotatably arranged on the rear leg 23 through the central shaft 32 so that the wheel socket 3 can drive the wheel to rotate around the central shaft 32. The second locking mechanism 5 is arranged on the frame 2 and is configured to lock the wheel socket 3. The second locking mechanism 5 includes a link mechanism member 51 and two positioning assemblies 52 connected to the link mechanism member 51. The positioning assembly 52 includes a first drag member 521, a second drag member 522, a positioning member, and a return member 524. The wheel socket 3 has a positioning portion, which may be the positioning hole 31. The positioning member may be a positioning pillar 523 configured to cooperate with the positioning hole 31. The positioning pillar 523 may be telescopically arranged in the positioning hole 31. The link mechanism member 51 is slidably arranged on the frame 2. One end of the first drag member 521 is connected to the link mechanism member 51, and the other end of the first drag member 521 is connected to the positioning member. The positioning member is movably arranged on the leg of the frame 2 and can be connected to or separated from the positioning portion. The return member 524 provides an elastic force to push the positioning member towards the positioning portion. The second drag member 522 is connected between the second locking module 14 and the link mechanism member 51. When the second drag member 522 is pulled, the second drag member 522 drives the two first drag members 521 to pull the two positioning pillars 523 so that the two positioning pillars 523 retract into the rear leg 23 and compress the return member 524 (for example, a spring), and pulls the link mechanism member 51 to slide relative to the frame 2. At this time, the two positioning pillars 523 are discharged from the positioning hole 31 of the wheel socket 3 to unlock the wheel socket 3. As a result, the wheel socket 3 can rotate around the central shaft 32

[0044] The unlocking device 1 is configured to unlock the first locking mechanism 4 and the second locking mechanism 5. Referring to FIGS. 2 and 3, the unlocking device 1 of the present invention includes at least one operating member 11, a selection member 12, a first unlocking module 13, and a second unlocking module 14. In this embodiment, the unlocking device 1 includes one operating member 11, but is not limited thereto. The operating member 11 is movably disposed on the frame 2. The selection member 12 is movably disposed on the frame 2. The sliding direction of the selection member 12 may intersect the sliding direction of the operating member 11. The first unlocking module 13 is movably disposed on the frame 2 and is connected to the first locking mechanism 4. The second unlocking module 14 is movably disposed on the frame 2 and is connected to the second locking mechanism 5. The selection member 12 can slide to drive the first unlocking module 13 and the second unlocking module 14 to move so that one of the first unlocking module 13 and the second unlocking module 14 moves to a position corresponding to the operating member 11. Next, the operating member 11 can move to drive the first unlocking module 13 to move to unlock the first locking mechanism 4, or to drive the second unlocking module 14 to move to unlock the second locking mechanism 5.

[0045] In another embodiment, the at least one operating member may include a first operating member and a second operating member configured to unlock the first locking mechanism and the second locking mechanism, respectively. In other words, the present invention may use two operating members to unlock two different locking mechanisms.

[0046] Referring to FIGS. 1 and 8, in this embodiment, the operation member 11 may slide upward and downward with respect to the frame 2, and the selection member 12 may slide leftward and rightward with respect to the frame 2. To avoid misoperation, the selection member 12 abuts against the operation member 11. The selection member 12 may slide away from the operation member 11 so that the operation member 11 may slide. Specifically, the selection member 12 has an abutting portion 123, and the abutting portion 123 abuts against the operation member 11 so that the selection member 12 may lock the operation member 11 by the abutting portion 123 to avoid misoperation. The first unlocking module 13 is disposed between the operation member 11 and the selection member 12. The first unlocking module 13 may be movably disposed on the selection member 12 and may slide upward and downward with respect to the selection member 12. The first unlocking module 13 abuts against the operation member 11. The first unlocking module 13 is connected to the wire of the first locking mechanism 4 and can drive the wire of the first locking mechanism 4 to move. The second unlocking module 14 is disposed between the operation member 11 and the selection member 12. The second unlocking module 14 may be movably disposed on the selection member 12 and may slide upward and downward with respect to the selection member 12. The second unlocking module 14 abuts against the operation member 11. The second unlocking module 14 is connected to the second drag member 522 of the second locking mechanism 5 and can drive the second drag member 522 to move. The first unlocking module 13 is located on the right side of the handle 21 of the frame 2, and the second unlocking module 14 is located on the left side of the handle 21 of the frame 2. However, the arrangement of the first unlocking module 13 and the second unlocking module 14 is not limited to the foregoing method. For example, the positions of the first unlocking module 13 and the second unlocking module 14 may be changed with respect to each other.

[0047] To unlock the first unlocking module 4 or the second unlocking module 5, the selection member 12 may slide to slide the first unlocking module 13 and the second unlocking module 14 so that the operating member 11 may slide to push one of the first unlocking module 13 and the second unlocking module 14. For further explanation, the selection member 12 may move between a first position (as shown in FIG. 6) and a second position (as shown in FIG. 4) with respect to the frame 2. When the selection member 12 is located at the first position, the operating member 11 may slide to drive and move the first unlocking module 13 to unlock the first locking mechanism 4. When the selection member 12 is located at the second position, the operating member 11 may slide to drive and move the second unlocking module 14 to unlock the second locking mechanism 5. Needless to say, in other embodiments, the first unlocking module 13 and the second unlocking module 14 may not contact the operating member 11. For example, the operating member 11 may be disposed in the space between the first unlocking module 13 and the second unlocking module 14. At this time, the selection member 12 may not contact the operating member 11.

[0048] Referring to FIGS. 3, 6, and 7, in this embodiment, the first unlocking module 13 includes a first rotating member 131 and a first sliding member 132. The first rotating member 131 is pivotally connected to the frame 2. The first locking mechanism 4 is connected to a position of the first rotating member 131 that is eccentric with respect to the rotation center of the first rotating member 131. The first sliding member 132 is slidably disposed on the frame 2. The sliding direction of the first sliding member 132 is the same as the sliding direction of the operating member 11. Specifically, the selection member 12 has a first receiving hole 121, and an end of the first sliding member 132 is slidably inserted into the first receiving hole 121. The other end of the first sliding member 132 abuts against the operating member 11. The first sliding member 132 is configured to drive the first rotating member 131 to rotate. When the operating member 11 slides to push the first sliding member 132, the first sliding member 132 drives the first rotating member 131 to rotate. Specifically, the first rotating member 131 has a first protruding portion 131a, and the first sliding member 132 has a first engaging groove 132a. The first protruding portion 131a is slidably disposed within the first engaging groove 132a. The first sliding member 132 can move to push the first protruding portion 131a to rotate the first rotating member 131. Due to the first engaging groove 132a, the first rotating member 131 can be stably disposed on the first sliding member 132. More specifically, the first rotating member 131 has a first connecting member 131b, and the first connecting member 131b is eccentric with respect to the rotation center of the first rotating member 131 and is connected to the first locking mechanism 4. The first rotating member 131 may have two first connecting members 131b. The two first connecting members 131b may be symmetrically disposed with respect to the first rotating member 131. The two first connecting members 131b are respectively connected to two wires of the first locking mechanism 4. In order to rotate the first rotating member 131, the operating member 11 may slide and be actuated to push the first sliding member 132 so that the first sliding member 132 slides to push the first protruding portion 131a.The first rotating member 131 rotates to pull the wire of the first locking mechanism 4 in order to unlock the frame 2. As a result, the frame 2 can be folded up.

[0049] Referring to FIGS. 3 to 5, in this embodiment, the second unlocking module 14 includes a second rotating member 141 and a second sliding member 142. The second rotating member 141 is pivotally connected to the frame 2. The second locking mechanism 5 is connected to the position of the second rotating member 141 that is eccentric with respect to the rotation center of the first rotating member 141. The second sliding member 142 is slidably disposed on the frame 2. The sliding direction of the second sliding member 142 is the same as the sliding direction of the operating member 11. That is, the sliding directions of the first and second sliding members 132 and 142 are both the same as the sliding direction of the operating member 11. Specifically, the selection member 12 has a second receiving hole 122, and an end of the second sliding member 142 is slidably inserted into the second receiving hole 122. The other end of the second sliding member 142 abuts against the operating member 11. The second sliding member 142 is configured to drive the second rotating member 141 to rotate. When the operating member 11 slides to push the second sliding member 142, the second sliding member 142 drives the second rotating member 141 to rotate. Specifically, the second rotating member 141 has a second protruding portion 141a, and the second sliding member 142 has a second engaging groove 142a. The second protruding portion 141a is slidably disposed in the second engaging groove 142a. The second sliding member 142 can move to push the second protruding portion 141a to rotate the second rotating member 141. Due to the second engaging groove 142a, the second rotating member 141 can be stably disposed on the second sliding member 142. More specifically, the second rotating member 141 has a second connecting member 141b, and the second connecting member 141b is eccentric with respect to the rotation center of the second rotating member 141 and is connected to the second locking mechanism 5. In order to rotate the second rotating member 141, the operating member 11 may slide to actuate so as to push the second sliding member 142 so that the second sliding member 142 slides to push the second protruding portion 141a. To unlock the wheel socket 3, the second rotating member 141 rotates to pull the second drag member 522 of the second locking mechanism 5, and the positioning post 523 is discharged from the positioning hole 31 of the wheel socket 3.As a result, the wheel socket 3 can rotate around the central shaft 32.

[0050] Referring to FIG. 3, in this embodiment, the first unlocking module 13 and the second unlocking module 14 are symmetrically arranged. The first unlocking module 13 and the second unlocking module 14 may be realized by the cooperation between the slide member and the rotating member, but are not limited thereto. In other embodiments, the first unlocking module 13 may only arrange the first slide member 132, and the first locking mechanism 4 is connected to the first slide member 132. The first slide member 132 may be pushed to slide to unlock the first locking mechanism 4. Alternatively, the second unlocking module 14 may only arrange the second slide member 142, and the second locking mechanism 5 is connected to the second slide member 142. The second slide member 142 may be pushed to slide to unlock the second locking mechanism 5. Alternatively, the first unlocking module 13 and the second unlocking module 14 may be asymmetrically arranged. One of the first unlocking module 13 and the second unlocking module 14 may be slidably arranged on the frame 2, and the other of the first unlocking module 13 and the second unlocking module 14 may be pivotally connected to the frame 2. For example, one of the first unlocking module 13 and the second unlocking module 14 may be a slide member slidably arranged on the frame 2, and the other of the first unlocking module 13 and the second unlocking module 14 may be a rotating member pivotally connected to the frame 2. The slide member and the rotating member are respectively connected to two different locking mechanisms and are configured to unlock the two different locking mechanisms.

[0051] Referring to FIGS. 3 and 9, in this embodiment, the first slide member 132 includes a first slide portion 132b, a first drive portion 132c connected to the first slide portion 132b, and a first limiting portion 132d connected to the first drive portion 132c. The first slide portion 132b is slidably inserted into the selection member 12. The first drive portion 132c is connected to the first rotating member 131. The first limiting portion 132d is disposed on the side of the first drive portion 132c. The second slide member 142 includes a second slide portion 142b, a second drive portion 142c connected to the second slide portion 142b, and a second limiting portion 142d connected to the second drive portion 142c. The second slide portion 142b is slidably inserted into the selection member 12. The second drive portion 142c is connected to the second rotating member 141. The second limiting portion 142d is disposed on the side of the second drive portion 142c. In order to prevent the other of the first unlocking module 13 and the second unlocking module 14 from interfering with the operating member 11, when the operating member 11 slides to press one of the first unlocking module 13 and the second unlocking module 14, a first accommodation space 15 is formed between the first slide member 132 and the operating member 11, and a second accommodation space 16 is formed between the second slide member 142 and the operating member 11. When the operating member 11 slides to press one of the first unlocking module 13 and the second unlocking module 14, the operating member 11 may be accommodated in the first accommodation space 15 or the second accommodation space 16.

[0052] Referring to FIGS. 10 to 13, the selection member 12 may move between a first position (as shown in FIG. 11) and a second position (as shown in FIG. 10) with respect to the frame 2. As shown in FIG. 11, when the selection member 12 is in the first position, the operating member 11 corresponds to the first unlocking module 13. As shown in FIG. 10, when the selection member 12 is in the second position, the operating member 11 corresponds to the second unlocking module 14. During the operation of the selection member 12, the following incorrect operations may occur. Essentially, the user operates the selection member 12 to slide it towards the second position, causing the operating member 11 to correspond to the second unlocking module 14. Then, the user operates the operating member 11 to slide it and press the second unlocking module 14 to unlock the second unlocking module 5. However, the user may accidentally operate the selection member 12 to slide it towards the first position, causing the operating member 11 to correspond to the first unlocking module 13. Then, the user presses and slides the operating member 11 to press the first unlocking module 13. If there is a child sitting on the stroller 100, the frame 2 may be folded, which may pose a hazard to the child sitting on the stroller 100. Therefore, in order to avoid the above-mentioned incorrect operations, the elastic member 17 may be disposed between the selection member 12 and the frame 2 and may be configured to move the selection member 12 away from the first position. When the user accidentally operates the selection member 12 to slide it towards the first position, the selection member 12 compresses the elastic member 17 due to the elastic member 17. After the user releases the selection member 12, the selection member 12 returns to its original position due to the elastic force of the elastic member 17. Next, the selection member 12 drives the first sliding member 132 of the first unlocking module 13 and the second sliding member 142 of the second unlocking module 14 to return to their original positions so that the operating member 11 cannot slide and press the first unlocking module 13. As a result, in order to enhance the safety of the stroller 100, the frame 2 is locked and cannot be folded. After the selection member 12 returns to its original position, the selection member 12 abuts against the operating member 11 again to lock the operating member 11. Specifically, the elastic member 17 may be a spring, but is not limited thereto.The elastic member 17 may be another elastic object. To position the elastic member 17 properly, the frame 2 has a protruding block 211, and the end of the elastic member 17 is sleeved to the protruding block 211, abuts against the frame 2, and the other end of the elastic member 17 may abut against the selection member 12. However, the present invention is not limited to the foregoing embodiments.

[0053] Referring to FIGS. 10 and 11, in the second preferred embodiment of the present invention, the elastic member 17 provides an elastic force to return the selection member 12 to the second position, and the second position of the selection member 12 may be set to be the initial state of the selection member 12. The operating member 11 may be directly pressed to press the second unlocking module 14 to unlock the second locking mechanism 5. When the frame 2 needs to be folded, the selection member 12 slides from the second position to the first position in order to correspond the operating member 11 to the first unlocking module 13 and must be held at the first position. Next, the operating member 11 can drive and slide the first unlocking module 13 to unlock the first locking mechanism 4. During the foregoing operations, the elastic member 17 is compressed and deformed. When the selection member 12 is released, the selection member 12 returns to the second position due to the elastic force of the elastic member 17.

[0054] Referring to FIG. 2, to facilitate the operation of the unlocking device 1 of the present invention, the unlocking device 1 may be disposed above the handle 21 of the frame 2. Needless to say, in other embodiments, the unlocking device 1 may be disposed at other positions of the frame 2.

[0055] It should be noted that the unlocking device 1 of the present invention is not limited to unlocking the frame folding mechanism and the wheel rotation direction mechanism. The first connecting member 131b of the first unlocking module 13 and the second connecting member 141b of the second unlocking module 14 may be connected to other locking mechanisms of the stroller, such as a handle rotation locking mechanism. Further, the unlocking device 1 of the present invention is not limited to being applied to a stroller. The unlocking device 1 may be used to unlock two different locking mechanisms in other fields.

[0056] Referring to FIGS. 3 to 7, the operation of the unlocking device 1 of the present invention is depicted as follows. First, the operating member 11 abuts simultaneously against the first sliding member 132 and the second sliding member 142. When it is necessary to unlock the first locking mechanism 4, the selection member 12 is operated to move leftward so as to be separated from the operating member 11 to unlock the operating member 11, driving the first unlocking module 13 and the second unlocking module 14 to move leftward. The second sliding member 142 of the second unlocking module 14 is also separated from the operating member 11, and the first sliding member 132 of the first unlocking module 13 still abuts against the operating member 11. When the operating member 11 is pushed, the operating member 11 slides upward, pushing the first sliding member 132 to slide. The first sliding member 132 slides to push the first protruding portion 131a, driving the first rotating member 131 to rotate. The first rotating member 131 rotates to pull the wire of the first locking mechanism 4 so that the frame 2 can be unlocked. As a result, the frame 2 can be folded. When it is necessary to unlock the second locking mechanism 5, the selection member 12 is operated to slide rightward so as to be separated from the operating member 11 to unlock the operating member 11, driving the first unlocking module 13 and the second unlocking module 14 to move rightward. The first sliding member 132 of the first unlocking module 13 is also separated from the operating member 11, and the second sliding member 142 of the second unlocking module 14 still abuts against the operating member 11. When the operating member 11 is pushed, the operating member 11 slides upward, pushing the second sliding member 142 to slide. The second sliding member 142 slides to push the second protruding portion 141a, driving the second rotating member 141 to rotate. The positioning post 523 is discharged from the positioning hole 31 of the wheel socket 3. Next, the second rotating member 141 rotates to pull the second drag member 522 of the second locking mechanism 5 so that the wheel socket 3 can be unlocked. As a result, the wheel socket 3 can rotate around the central shaft 32.

[0057] Referring to FIGS. 14 and 15, the unlocking device 1 of the present invention may further include a holding mechanism 6 disposed on the operating member 11. The holding mechanism 6 can hold the operating member 11 at an unlocking position (as shown in FIG. 15) when the operating member 11 slides to unlock one of the first locking mechanism 4 and the second locking mechanism 5. Further, the holding mechanism 6 can release the operating member 11 when the operating member 11 is actuated from the unlocking position.

[0058] In this embodiment, the holding mechanism 6 may include a first engaging member 61 and a second engaging member 62. The first engaging member 61 is fixed to the operating member 11. The second engaging member 62 is connected to the frame 2. If the unlocking device 1 is disposed on the handle 21 of the frame 2, the second engaging member 62 may be disposed and connected to the handle 21 of the frame 2. The first engaging member 61 has a first inclined groove 611, a second inclined groove 612, a third inclined groove 613, and a fourth inclined groove 614 that are connected to each other. The end of the second engaging member 62 has an engaging portion 621.

[0059] When the user presses the operating member 11 to unlock the first locking mechanism 4 or the second locking mechanism 5, the engaging portion 621 of the second engaging member 62 moves along the first and second inclined grooves 611, 612, and then engages with the recess 615 between the second and third inclined grooves 612, 613 to hold the operating member 11 at the unlocking position (as shown in FIG. 15). At this time, the first locking mechanism 4 and the second locking mechanism 5 are held at the unlocking position. Further, when the operating member 11 is actuated from the unlocking position (that is, when the operating member 11 located at the unlocking position is pressed again), the engaging portion 621 of the second engaging member 62 is disengaged from the recess 615 and moves along the third and fourth inclined grooves 613, 614 to release the operating member 11.

[0060] For example, the second locking mechanism 5 may be a wheel rotation direction mechanism. When the operating member 11 is pushed to unlock the wheel rotation direction mechanism, the holding mechanism 6 holds the operating member 11 at the unlocked position so that the wheel can still rotate freely even if the user releases the operating member 11. Further, when the operating member 11 is actuated from the unlocked position, the holding mechanism 6 releases the operating member 11 so that the operating member 11 slides to lock the wheel rotation direction mechanism, and then the wheel is locked.

[0061] Referring to FIGS. 16 and 17, at least one operating member of the present invention may include a first operating member 111 and a second operating member 112. The first operating member 111 slides to drive the first unlocking module 13 to move and unlock the first locking mechanism 4, and the second operating member 112 slides to drive the second unlocking module 14 to move and unlock the second locking mechanism 5. In other words, the present invention may use two operating members 111 and 112 to unlock two different locking mechanisms 4 and 5. In this embodiment, the holding mechanism 6 may be disposed on the second operating member 112, but it is not limited thereto. In another embodiment, the holding mechanism 6 may be disposed on the first operating member 111.

[0062] When the user presses the second operating member 112 to unlock the second locking mechanism 5, the engaging portion 621 of the second engaging member 62 moves along the first and second inclined grooves 611 and 612, and then engages with the recess 615 between the second and third inclined grooves 612 and 613 to hold the second operating member 112 at the unlocked position (as shown in FIG. 17). At this time, the second locking mechanism 5 is held at the unlocked position. Further, when the second operating member 112 is actuated from the unlocked position (i.e., when the second operating member 112 located at the unlocked position is pressed again), the engaging portion 621 of the second operating member 62 is disengaged from the recess 615 so that the second operating member 112 slides to lock the second locking mechanism 5, and then moves along the third and fourth inclined grooves 613 and 614 to release the second operating member 112.

[0063] In an exemplary embodiment, the second locking mechanism 5 may be, without limitation, one of the locking mechanisms that need to hold or maintain a state, such as wheel braking and wheel swing locking. The first locking mechanism 4 may be, without limitation, one of the locking mechanisms for handle conversion, wheel braking, handle angle adjustment, frame folding, and wheel swing locking, but their functions do not overlap with each other.

[0064] Referring to FIGS. 18 and 19, the holding mechanism 7 is pivotally connected to the operating member 11 and includes an engaging portion 71 and an elastic portion 72. Further, the frame 2 has an engaging hole 24. In this embodiment, the operating member 11 may be configured to unlock the aforementioned second locking mechanism 5. As shown in FIG. 18, the engaging portion 71 of the holding mechanism 7 abuts against the frame 2, and the elastic portion 72 of the holding mechanism 7 is compressed by the frame 2 before the operating member 11 slides to unlock the second locking mechanism 5. As shown in FIG. 19, when the operating member 11 slides to unlock the second locking mechanism 5, the elastic portion 72 provides an elastic force to drive and rotate the holding mechanism 7 so that the operating member 11 is held at the unlocked position, and the engaging portion 71 engages with the engaging hole 24. The user presses the holding mechanism 7 to disengage the engaging portion 71 from the engaging hole 24 to release the operating member 11 so that the operating member 11 slides to lock the second locking mechanism 5.

[0065] Referring to FIGS. 20 to 24, at least one operating member of the present invention may include a first operating member 111 and a second operating member 112. The first operating member 111 slides to drive the first sliding member 132 to move and unlock the first locking member. The second operating member 112 slides to drive the second sliding member 142 to move and unlock the second locking mechanism 5. In this embodiment, the selection member 12 is movably disposed on the aforementioned frame 2 so that it can move between a first position (as shown in FIG. 21) and a second position (as shown in FIG. 23) with respect to the aforementioned frame 2. First, as shown in FIG. 20, the first sliding member 132 and the second sliding member 142 abut against the selection member 12. When the first locking mechanism 4 needs to be unlocked, the selection member 12 is operated to move leftward (as shown in FIG. 21) so that the selection member 12 is separated from the first sliding member 132 to unlock the first operating member 111, and the second sliding member 142 still abuts against the selection member 12. At this time, the first accommodation space 15 is formed between the first sliding member 132 and the selection member 12. When the first operating member 111 is pushed (as shown in FIG. 22), the first operating member 111 slides upward to push and slide the first sliding member 132 in order to unlock the first locking mechanism 4. When the second locking mechanism 5 needs to be unlocked, the selection member 12 is operated to move rightward (as shown in FIG. 23) so that the selection member 12 is separated from the second sliding member 142 to unlock the second operating member 112, and the first sliding member 132 still abuts against the selection member 12. At this time, the second accommodation space 16 is formed between the second sliding member 142 and the selection member 12. When the second operating member 12 is pushed (as shown in FIG. 24), the second operating member 112 slides upward to push and slide the second sliding member 142 in order to unlock the second locking mechanism 5. Since how to unlock the first and second locking mechanisms 4 and 5 is described in detail above, repetitive descriptions are not described here again.

[0066] Referring to FIGS. 25 to 28, at least one operating member of the present invention may include a first operating member 111 and a second operating member 112. The first operating member 111 slides to drive the first sliding member 132 to unlock the first locking mechanism 4, and the second operating member 112 slides to drive the second sliding member 142 to unlock the second locking mechanism 5. In this embodiment, the selection member 12 is pivotally connected to the aforementioned frame 2 such that the selection member 12 can rotate between a first position (as shown in FIG. 27) and a second position (as shown in FIG. 25) with respect to the aforementioned frame 2. First, the selection member 12 is disposed at the second position such that the selection member 12 is separated from the second sliding member 142 to unlock the second operating member 112, and the first sliding member 132 abuts against the selection member 12 to lock the first operating member 111. At this time, a second accommodation space 16 is formed between the second sliding member 142 and the selection member 12. In this embodiment, a torsion spring or the like can be used to maintain the selection member 12 at the second position. When the second operating member 112 is pushed (as shown in FIG. 26), the second operating member 112 slides upward to push and slide the second sliding member 142 in order to unlock the second locking mechanism 5. When it is necessary to unlock the first locking mechanism 4, the selection member 12 is operated to rotate counterclockwise (as shown in FIG. 27) such that the selection member 12 is separated from the first sliding member 132 to unlock the first operating member 111, and the second sliding member 142 abuts against the selection member 12 to lock the second operating member 112. At this time, a first accommodation space 15 is formed between the first sliding member 132 and the selection member 12. When the first operating member 111 is pushed (as shown in FIG. 28), the first operating member 111 slides upward to push and slide the first sliding member 132 in order to unlock the lock of the first locking mechanism 4. It should be noted that if the selection member 12 is released from the first position shown in FIG. 27, the torsion spring rotates the selection member 12 to the second position shown in FIG. 25 to avoid misoperation of the first operating member 111.How to unlock the first and second locking mechanisms 4 and 5 has been described in detail above, so repetitive explanations will not be described again here.

[0067] As described above, the present invention uses at least one operating member to drive and move the first unlocking module to unlock the first locking mechanism, or to drive and move the second unlocking module to unlock the second locking mechanism. In an embodiment, the selection member is movably disposed on the frame and can move between a first position and a second position with respect to the frame. When the selection member is disposed at the first position, the first locking mechanism corresponds to the operating member such that the operating member can drive and move the first unlocking module to slide to unlock the first locking mechanism. When the selection member is disposed at the second position, the second locking mechanism corresponds to the operating member such that the operating member can drive and move the second unlocking module to slide to unlock the second locking mechanism. Therefore, the present invention does not need to arrange two independent unlocking devices to unlock the first and second locking mechanisms. That is, the present invention can unlock two different locking mechanisms using a single unlocking device. Therefore, the manufacturing cost is reduced, and the unlocking device of the present invention occupies less space in the stroller and is easy and convenient to operate.

[0068] In another embodiment, the present invention may use a holding mechanism to hold the operating member at the unlocking position when the operating member slides to unlock the first locking mechanism and the second locking mechanism. Accordingly, the first locking mechanism and the second locking mechanism can be held in the unlocked state until the operating member is actuated from the unlocking position. For example, the second locking mechanism may be a wheel rotation direction mechanism, and the holding mechanism may hold the operating member at the unlocking position when the operating member slides to unlock the second locking mechanism. When the user presses the operating member to unlock the wheel rotation direction mechanism, the wheel rotation direction mechanism is held at the unlocking position so that the wheel can still rotate freely even if the user releases the operating member. Further, when the operating member is actuated from the unlocking position, the holding mechanism releases the operating member so that the operating member slides to lock the wheel rotation direction mechanism and then the wheel is locked.

[0069] Those skilled in the art will readily observe that many modifications and changes may be made to the apparatus and methods while retaining the teachings of the present invention. Accordingly, the foregoing disclosure should be construed as being limited only by the boundaries of the appended claims.
