Description

Technical Field

[0001] The present invention relates to a baby carriage, and more particularly to an adapter device adapted to a baby carriage and its connection mechanism.

Background Art

[0002] Various types of baby carriages (e.g., strollers, car seats, bassinets, cribs, etc.) are widely used in households with infants. For example, bassinets are mainly suitable for infants up to about 15 months old. A bassinet can be attached to the base of a car seat to avoid or reduce vibrations and impacts caused by brakes or vehicle collisions, protecting the infant. Since a bassinet can be carried after getting out of the car or when going out, it is convenient for carrying an infant. A bassinet can also be used alone at home, enhancing the convenience of using a bassinet.

[0003] To reduce the burden on caregivers when going out, bassinets used in special strollers have been developed to facilitate carrying infants. However, this type of bassinet can only be used with special strollers and not with other baby carriages, so there are limitations in using this bassinet and it is not yet convenient enough.

[0004] Therefore, there is a need to provide an adapter device that enables a bassinet to be used with various baby carriages and reduces storage space.

Embodiments for Carrying Out the Invention

[0037] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, where similar numbers in the drawings represent similar elements.

[0038] As shown in FIGS. 1 to 29, the adapter device 1 of the present invention is mainly used for connecting an infant accommodation device or installing the infant accommodation device on a different baby carriage so that the infant accommodation device can be used more flexibly. Here, the infant accommodation device is a bassinette, a safety seat, etc., and the baby carriage is a stroller, a baby bed, a diaper changing table, a safety seat base, etc. It should be noted that the infant accommodation device and the baby carriage are not limited to the above products, and any other infant products may be used.

[0039] As shown in FIGS. 1 to 4, 18, 19, and 23, the adapter device 1 of the present invention includes a first support member 100, a second support member 200, and a connection mechanism 300 for connecting the first support member 100 and the second support member 200. The first support member 100 and the second support member 200 are substantially U-shaped. The first support member 100 and the second support member 200 are connected to each other by two connection mechanisms 300. The adapter device 1 can be folded and unfolded by the two connection mechanisms 300. Further, the two connection mechanisms 300 can be detachably connected to a stroller, and the infant accommodation device can be selectively attached to different strollers according to different requirements. When the adapter device 1 is not in use, (as shown in FIGS. 2, 4, and 29) the adapter device 1 can be pivoted and folded.

[0040] Referring to FIGS. 1 to 23, different embodiments of the adapter device 1 of the present invention will be described below.

[0041] As shown in FIGS. 1 to 7, in the first embodiment of the adapter device 1 of the present invention, the two connection mechanisms 300 have the same structure and are symmetrically arranged. One connection mechanism 300 is exemplified below for the purpose of explanation. Specifically, the connection mechanism 300 includes a first joint 310, a second joint 320, a fixed base 330, a connecting member 340, a locking pin 350, a unlocking operation member 360, and a return member 370. The second joint 320 is pivotally connected to the first joint 310. The first support member 100 is connected to one of the first joint 310 and the second joint 320. The second support member 200 is connected to the other of the first joint 310 and the second joint 320. The locking pin 350 is movably disposed between the first joint 310 and the second joint 320 and is configured to lock or unlock the first joint 310 and the second joint 320.

[0042] The unlocking operation member 360 is connected to the lock pin 350 and configured to drive the lock pin 350 to disengage from the first joint 310 and / or the second joint 320, thereby unlocking the first joint 310 and the second joint 320. The return member 370 abuts against the unlocking operation member 360 and has a tendency to return the unlocking operation member 360 to its initial position. Further, the connecting member 340 is disposed between the first joint 310 and the second joint 320. When one of the first joint 310 and the second joint 320 receives a force, the other of the first joint 310 and the second joint 320 is pivotally driven by the connecting member 340, enabling the adapter device 1 to be folded more conveniently and easily. The fixed base 330 is connected to the first joint 310 or the second joint 320 and configured to be detachably connected to the stroller.

[0043] In this embodiment, the first joint 310 is fixed to the first support member 100, the second joint 320 is fixed to the second support member 200, and the connection shaft 331 protrudes from the fixed base 330. The connection shaft 331 passes through the second joint 320 and is pivotally connected to the first joint 310 such that the second joint 320 is sandwiched between the fixed base 330 and the first joint 310. The unlocking operation member 360 is pivotally connected to the first joint 310 and connected to the lock pin 350. When a force is applied to rotate the unlocking operation member 360, the lock pin 350 is driven to move and the lock is released. Of course, the arrangement positions of the first joint 310 and the second joint 320 may be reversed.

[0044] As shown in FIG. 1, the adapter device 1 further includes a tension member 400. The unlocking operation members 360 of the two connection mechanisms 300 are connected to each other by the tension member 400. Therefore, by pulling the tension member 400, the two connection mechanisms 300 can be driven simultaneously to unlock, making the operation of folding the adapter device 1 more convenient. The tension member 400 may be a webbing, a steel rope, a plastic strip, or other ropes, but the present invention is not limited thereto.

[0045] As shown in FIGS. 6 to 11, in this embodiment, the connecting member 340 may be a gear pivotally connected between the first joint 310 and the second joint 320. A plurality of protruding teeth 340a are formed on the outer side of the connecting member 340. The first joint 310 has a plurality of first gear teeth 311 that mesh with the protruding teeth 340a of the connecting member 340. The second joint 320 has a plurality of second gear teeth 321 that mesh with the protruding teeth 340a of the connecting member 340. Therefore, when either the first joint 310 or the second joint 320 receives a force, due to the interaction between the first gear teeth 311, the protruding teeth 340a, and the second gear teeth 321, the first joint 310 and the second joint 320 pivot relative to each other. Needless to say, the connecting member 340 is not limited to a gear, and other components can be used to connect the first joint 310 and the second joint 320.

[0046] As shown in FIGS. 6 to 12, the connection base 312 protrudes from one side of the first joint 310 (as shown in FIGS. 7 and 9), and the inner diameter of the connection base 312 corresponds to the outer diameter of the connection shaft 331. The first joint 310 is pivotally connected to the connection shaft 331 via the connection base 312. The first gear teeth 311 are arranged on the outer wall of the connection base 312 (as shown in FIGS. 7 and 9). The second joint 320 is circular, and the second gear teeth 321 are arranged on the inner wall of the second joint 320 (as shown in FIGS. 6, 8, and 11).

[0047] When the second joint 320 is pivotally connected to the first joint 310, the first gear tooth 311 and the second gear tooth 321 are separated from each other along the radial direction of the two joints (as shown in FIG. 12). Further, a connection post 332 is configured to protrude from the fixed base 330. The connecting member 340 is pivotally connected to the connection post 332 and meshes with the second gear tooth 321. The connecting member 340 protrudes from the second joint 320 along the axial direction of the connection post 332 (as shown in FIG. 8) so that the connecting member 340 can extend into the first joint 310 and mesh with the first gear tooth 311.

[0048] Preferably, the connection mechanism 300 can include a plurality of connecting members 340 regularly arranged around the connection shaft 331, and the connection shaft 331 is the pivot axis of the first joint 310 and the second joint 320. In this embodiment, there are three connecting members 340 arranged regularly on the fixed base 330 parallel to the connection shaft 331. Of course, the number of the connecting members 340 is not limited to three.

[0049] As shown in FIGS. 12 to 14, FIG. 12 is a cross-sectional view showing the connection mechanism 300 when the adapter device 1 is deployed. When the lock of the connection mechanism 300 is released and the first support member 100 rotates in the direction indicated by the arrow F1 in FIG. 12, the first support member 100 drives the first joint 310 to rotate synchronously. At this time, the first gear teeth 311 of the first joint 310 act on the protruding teeth 340a to rotate the connecting member 340 in the reverse direction. That is, the connecting member 340 rotates along the direction indicated by the arrow F2 in FIG. 12. Thereby, it acts on the second gear teeth 321 to drive the second joint 320 and rotate it along the direction indicated by the arrow F2 in FIG. 12. That is, the rotation direction of the second joint 320 is opposite to the rotation direction of the first joint 310. Therefore, only one hand is required to push the first support member 100 for pivoting, and the second support member 200 is driven to rotate in the reverse direction (as shown in FIG. 13) toward the first support member 100. Therefore, the folding operation is made easier and labor-saving. Next, the first support member 100 and the second support member 200 rotate to the terminal positions where they are folded, as shown in FIG. 14. The folded adapter device 1 is shown in FIGS. 2 and 4. Naturally, when the second support member 200 receives a force, the first support member 100 and the second support member 200 can also pivot relative to each other.

[0050] As shown in FIGS. 5 to 8 and 15 to 17, in this embodiment, the second joint 320 has a lock hole 322, the first joint 310 has a through hole 313 corresponding to the lock hole 322, and the lock pin 350 is slidably connected within the through hole 313. The end of the lock pin 350 protrudes from the first joint 310 and connects to the unlocking operation member 360. The unlocking operation member 360 can drive the lock pin 350 to slide within the through hole 313 such that the other end of the lock pin 350 is removably engaged with the lock hole 322. Of course, a lock hole may be formed in the first joint 310, and the unlocking operation member 360 may be disposed at the second joint 320 or other positions and connected to the lock pin 350. In this way, the lock pin 350 can also be slidably driven to be removably engaged with the lock hole.

[0051] As shown in FIGS. 6, 8, and 15, the second joint 320 further has a restraint groove 323. The restraint groove 323 is arc-shaped and is arranged coaxially with the pivot axis (connection shaft 331) of the first joint 310 and the second joint 320. The lock hole 322 is located at the end of the restraint groove 323. In this way, when the first joint 310 and the second joint 320 pivot relative to each other, the lock pin 350 engages within the restraint groove 323 and slides along the restraint groove 323.

[0052] As shown in FIGS. 16 and 17, the lock pin 350 may include a lock rod 351 and a connection head 352 disposed at the end of the lock rod 351. The connection head 352 is formed as a sheet structure and has a longitudinal hole 353. The shaft member 354 is disposed within the longitudinal hole 353 and is pivotally connected to the unlocking operation member 360. When the unlocking operation member 360 rotates, the unlocking operation member 360 slides the lock pin 350 such that the other end of the lock rod 351 away from the connection head 352 is removably engaged with the lock hole 322.

[0053] As shown in FIGS. 1, 2, 5 to 7, and 15 to 17, the unlocking operation member 360 includes a pivoting portion 361 and an operating portion 362. The pivoting portion 361 is pivotally connected to the first joint 310 by a shaft 3611 (as shown in FIG. 5). The axial direction of the shaft 3611 is perpendicular to the axial direction of the pivot axis of the first joint 310. When the operating portion 362 receives a force, the unlocking operation member 360 pivots about the shaft 3611, driving the lock pin 350 to slide and release the lock. The return member 370 abuts against the unlocking operation member 360. When the unlocking operation member 360 pivots, the return member 370 deforms. When the return member 370 returns, the return member 370 drives the unlocking operation member 360 to return.

[0054] In this embodiment, the pivoting portion 361 protrudes from the end of the unlocking operation member 360. The pivoting portion 361 is pivotally connected to the recess 314 at the end of the first joint 310 by a shaft 3611 (as shown in FIGS. 5 to 7). The other end of the unlocking operation member 360 forms the operation portion 362. The return member 370 is disposed between the pivoting portion 361 and the operation portion 362 by a fixing member 371. Specifically, the unlocking operation member 360 has a longitudinal hole 363. The longitudinal hole 363 extends along the direction from the pivoting portion 361 toward the operation portion 362. As shown in FIG. 6, the first abutting portion 364 protrudes from the inner wall toward the center of the longitudinal hole 363. Further, the end of the fixing member 371 has a second abutting portion 3711. The fixing member 371 is disposed in the longitudinal hole 363, and the end of the fixing member 371 is fixed to the first joint 310. The second abutting portion 3711 is located outside the first joint 310 and is away from the first joint 310. As shown in FIGS. 1, 2, 5, and 6, the return member 370 is sleeved on the fixing member 371, and both ends of the return member 370 abut against the first abutting portion 364 and the second abutting portion 3711. When the operation portion 362 is pulled and the unlocking operation member 360 pivots about the shaft 3611 (that is, the unlocking operation member 360 rotates along the direction indicated by the arrow F3 shown in FIGS. 1 and 16), the first abutting portion 364 compresses the return member 370 so that the return member 370 is deformed. When the operation portion 362 is released, the return member 370 returns, and the unlocking operation member 360 is driven to return (that is, the unlocking operation member 360 rotates in the reverse direction of the arrow F3 and changes from the state shown in FIG. 17 to the state shown in FIG. 16). Thereby, the lock pin 350 engages with the lock hole 322 or the restraint groove 323.

[0055] As shown in FIGS. 1, 5, and 6, the operation portion 362 has a through hole 3621. The tension member 400 is connected by the through hole 3621, which makes the connection more convenient.

[0056] As shown in FIGS. 5, 7, 16, and 17, the interior of the unlocking operation member 360 further has an engaging groove 365 (as shown in FIG. 7), and the extending direction of the engaging groove 365 is substantially the same as the extending direction of the vertical hole 363. The connecting head 352 of the lock pin 350 engages with the engaging groove 365. The shaft member 354 is disposed in the vertical hole 353 of the connecting head 352 and is connected to the side wall of the engaging groove 365 (as shown in FIGS. 16 and 17). When the unlocking operation member 360 rotates along the direction of arrow F3 shown in FIG. 16 or in the direction opposite to arrow F3, the lock pin 350 is slidably driven by the interaction between the shaft member 354 and the vertical hole 353.

[0057] Of course, the unlocking operation member 360 and the return member 370 are not limited to the arrangement of the present embodiment and may be realized by other structures shown below.

[0058] As shown in FIGS. 3, 4, 7, 8, and 10 - 14, the connecting mechanism 300 further includes a slide block 380 and a connecting rod 390. The slide block 380 is slidably connected to the fixed base 330 and is located on the side away from the second joint 320. The connecting rod 390 is curved and is disposed between the fixed base 330 and the second joint 320. One end of the connecting rod 390 is connected to the slide block 380, and the other end of the connecting rod 390 is pivotally connected to the second joint 320. When the second joint 320 pivots, the connecting rod 390 drives the slide block 380 to slide back and forth.

[0059] As shown in FIGS. 3, 4, and 7, the fixed base 330 has a slide groove 333 for installing the slide block 380. The slide groove 333 extends along the direction from top to bottom of the fixed base 330. A vertical hole 334 is further formed in the slide groove 333. A shaft member 381 disposed in the vertical hole 334 connects the slide block 380 and the end of the connecting rod 390. Further, as shown in FIG. 11, a breach 324 is formed in the side wall of the second joint 320. The other end of the connecting rod 390 is pivotally connected to the breach 324. The breach 324 provides a space for the connecting rod 390 to pivot.

[0060] As shown in FIGS. 3, 4, and 10 - 14, when the adapter device 1 is deployed, (as shown in FIG. 3) the slide block 380 is located at the upper part of the slide groove 333. When the first joint 310 and the second joint 320 pivot and fold, the second joint 320 moves the connecting rod 390 to drive the slide block 380 and slide it downward along the slide groove 333 (i.e., slide along the direction of arrow F4 shown in FIG. 3). When the first joint 310 and the second joint 320 are completely folded, (as shown in FIGS. 4 and 14) the slide block 380 slides to the bottom of the slide groove 333. When the slide block 380 slides downward, the slide block 380 drives an unlock device disposed on the stroller to release the lock, and the adapter device 1 and the stroller are folded synchronously.

[0061] As shown in FIGS. 1 - 10, in this embodiment, the fixed base 330 can further have an engaging protrusion 335 for engaging with the stroller and a button 336 for protruding or retracting the engaging protrusion 335. Since the structures and principles of the engaging protrusion 335 and the button 336 are well - known to those skilled in the art, the description is omitted here.

[0062] When it is necessary to connect the bassinette to the adapter device 1, the adapter device 1 needs to be deployed first. At this time, as shown in FIGS. 1 and 3, the first support member 100 and the second support member 200 extend in opposite directions. The adapter device 1 can be placed directly on the ground or platform, and then the bassinette can be engaged with the adapter device 1. The connection between the bassinette and the adapter device 1 is well known to those skilled in the art. Since the adapter device 1 can prevent the bassinette from shaking, the infants sitting in the bassinette will feel more comfortable. Further, the adapter device 1 can be engaged with a stroller. That is, the fixed base 330 can be engaged with the engagement mechanism of the stroller to install the bassinette on the stroller.

[0063] When the adapter device 1 is not needed, the bassinette, the adapter device 1 and the stroller can be detached and folded from each other, or the adapter device 1 can be directly folded together with the stroller. Specifically, the tension member 400 can be pulled upward so that the tension member 400 shown in FIGS. 1 to 18 pulls the unlocking operation member 360 of the two connection mechanisms 300 and pivots synchronously. The unlocking operation member 360 drives the locking pin 350 to slide out of the locking hole 322 of the second joint 320 and disengage as shown in FIG. 17. The return member 370 is compressed during the above process. Next, after pushing the first support member 100 and rotating it by a predetermined angle, the tension member 400 is released. The unlocking operation member 360 is returned by the return member 370, and is driven so that the locking pin 350 slides toward the second joint 320, and the locking pin 350 engages with the restraint groove 323 as shown in FIGS. 6 and 8.

[0064] Next, press the first support member 100 and rotate it in the direction of arrow F1 in FIG. 12. The first support member 100 drives the second support member 200 to rotate along the direction indicated by arrow F2 in FIG. 12 until the first support member 100 and the second support member 200 pivot to the folded state shown in FIGS. 2, 4, and 14. At this time, the lock pin 350 slides within the restraint groove 323 as shown in FIG. 15. For the folded state of the adapter device 1, reference can further be made to FIGS. 2 and 4.

[0065] Furthermore, when the first support member 100 and the second support member 200 pivot and fold, the second joint 320 drives the slide block 380 to slide downward along the fixed base 330 by the connecting rod 390. Accordingly, the slide block 380 drives the engagement mechanism of the stroller to unlock, and the adapter device 1 can be folded together with the stroller. That is, it is not necessary to remove the adapter device 1 from the stroller. The folding operation is simpler.

[0066] As shown in FIGS. 18 to 22, in the second embodiment of the present invention, the difference between the adapter device 1 and the aforementioned first embodiment lies in the arrangement of the unlocking operation member 360' and the return member 370'. Only the differences will be shown below, and other similar points will not be described again.

[0067] Specifically, in this embodiment, the pivoting portion 361' is formed substantially in the middle portion of the unlocking operation member 360' and is pivotally connected to the first joint 310 by a shaft 3611'. After the pivotal connection, the axial direction of the shaft 3611' is perpendicular to the axial direction of the pivot axis of the first joint 310. The operation portion 362' is formed at the lower end of the unlocking operation member 360'. The return member 370' abuts against the upper end of the unlocking operation member 360' and the first joint 310.

[0068] As shown in FIG. 22, the upper end of the unlocking operation member 360' has a first protruding support column 366 protruding from the side surface, and the first joint 310 has a second protruding support column 315 corresponding to the first protruding support column 366. Both ends of the return member 370' are sleeved on the first protruding support column 366 and the second protruding support column 315 respectively, and are in contact with the unlocking operation member 360' and the first joint 310. Therefore, when the operation part 362' is pulled and moves away from the first joint 310, the unlocking operation member 360' pivots about the shaft 3611' (that is, the unlocking operation member 360' pivots about the shaft 3611' in the direction indicated by the arrow F3 shown in FIG. 22), and the upper end of the unlocking operation member 360' moves close to the first joint 310, compressing and deforming the return member 370'. When the operation part 362' is released, the return member 370' returns and drives the unlocking operation member 360' to return (that is, drives the unlocking operation member 360' to return in the reverse direction of the arrow F3 in FIG. 22).

[0069] In this embodiment, the folding and unfolding operations and principles of the adapter device 1 are the same as those of the foregoing embodiments, so the repeated descriptions are omitted here.

[0070] As shown in FIGS. 20 and 22, in this embodiment, the first joint 310 and the second joint 320 are not limited to being locked by a lock pin, and may be locked by other methods. For example, the unlocking operation member 360' can be directly engaged with the second joint 320. Specifically, the operation portion 362' of the unlocking operation member 360' is bent (as shown in FIGS. 20 and 22) to form the engaging portion 367 and extends toward the second joint 320. A lock breach 325 is formed at the edges of the second joint 320 and the first joint 310 (as shown in FIGS. 20 and 22) and corresponds to the engaging portion 367. When the unlocking operation member 360' is in the initial position, the engaging portion 367 crosses the outer edge of the first joint 310 and engages with the lock breach 325 of the second joint 320 (as shown in FIGS. 20 and 22). At this time, the first joint 310 and the second joint 320 cannot rotate relative to each other. When the operation portion 362' is pulled and the unlocking operation member 360' is driven to pivot, the engaging portion 367 is disengaged from the lock breach 325. On the other hand, the first joint 310 and the second joint 320 can rotate relative to each other.

[0071] As shown in FIGS. 23 to 29, in the third embodiment of the present invention, the difference between the adapter device 1 and the foregoing first embodiment lies in the structure of the connecting member 340 and the connection method between the first joint 310 and the second joint 320. Only the differences will be shown below, and other similar points will not be described again.

[0072] In this embodiment, the connecting member 340 includes a first connecting rod 341 and a second connecting rod 342. Here, the first end 3411 of the first connecting rod 341 is pivotally connected to the first joint 310 to form a first pivot point P1. The first end 3421 of the second connecting rod 342 is pivotally connected to the second joint 320 to form a second pivot point P2. And the second end 3412 of the first connecting rod 341 is pivotally connected to the second end 3422 of the second connecting rod 342 to form a third pivot P3. Further, the centers of the pivot axes of the first joint 310 and the second joint 320 form a fourth pivot point P4, and the fourth pivot point P4 is located above the third pivot point P3. The first pivot point P1, the third pivot point P3, the second pivot point P2, and the fourth pivot point P4 are sequentially connected to form a four-bar linkage mechanism. When either the first joint 310 or the second joint 320 receives a force, due to the interaction between the first connecting rod 341 and the second connecting rod 342, the four pivot points of the aforementioned four-bar linkage mechanism pivot relative to each other, pulling and pivoting the other of the first joint 310 and the second joint 320. Therefore, the first joint 310 and the second joint 320 can be automatically folded, and the folding operation is made easier and labor-saving.

[0073] As shown in FIGS. 23 to 27, in this embodiment, the first connecting rod 341 and the second connecting rod 342 are disposed between the second joint 320 and the fixed base 330.

[0074] Specifically, the slide hole 326 is formed on and penetrates through the second joint 320. The slide hole 326 is arc-shaped and is arranged coaxially with the pivot axes of the first joint 310 and the second joint 320 (that is, the slide hole 326 is centered on the fourth pivot point P4). At the same time, the support column 316 is arranged on the first joint 310 and protrudes therefrom. The support column 316 is slidably arranged within the slide hole 326. The support column 316 extends towards the fixed base 330. The support column 316 is pivotally connected to the first end 3411 of the first connecting rod 341 as shown in FIG. 24.

[0075] As shown in FIG. 23, the second end 3412 of the first connecting rod 341 is pivotally connected to the second end 3422 of the second connecting rod 342 by a shaft member 381. The shaft member 381 is slidably arranged within the vertical hole 334 of the fixed base 330 and is connected to the slide block 380. Therefore, when the first joint 310 and the second joint 320 pivot and approach each other, the first joint 310 and the second joint 320 drive the shaft member 381 to slide downward along the vertical hole 334, whereby, as shown in FIGS. 28 and 29, the slide block 380 also slides downward along the slide groove 333. Therefore, in this embodiment, the four-section connecting mechanism achieves connection when the first joint 310 and the second joint 320 are folded, and further simplifies the connection structure between the first joint 310 and the second joint 320 by driving the slide block 380 to slide downward synchronously.

[0076] In this embodiment, the slide groove 333 of the fixed base 330 stands upright along the central axis L of the fixed base 330, and the vertical hole 334 of the slide groove 333 also stands upright along the central axis L.

[0077] Note that the parts not described in detail in this embodiment are the same as those in the above-described first embodiment.

[0078] Referring again to FIGS. 23 to 29, the pivoting and folding operations of the adapter device 1 in this embodiment will be described. As shown in FIGS. 23 and 28, when the adapter device 1 is deployed, the slide block 380 is located at the upper part of the slide groove 333. At this time, the first connecting rod 341 and the second connecting rod 342 are in the positions shown in FIG. 26. When the lock release operation member 360 is pulled to release the lock, the first support member 100 and the second support member 200 can be pushed and pivoted to be folded. The specific operation is as follows.

[0079] When the first support member 100 is pushed and rotated along the direction of arrow F1 shown in FIG. 23, the first support member 100 drives the first joint 310 to rotate synchronously. During the rotation of the first joint 310, the column 316 of the first joint 310 slides within the slide hole 326 of the second joint 320 as shown in FIG. 27. The column 316 drives the first end 3411 of the first connecting rod 341 to slide along the slide hole 326 (that is, the first end 3411 of the first connecting rod 341 rotates around the fourth pivot point P4), and as a result, the first end 3411 of the first connecting rod 341 descends as shown in FIG. 27. During the movement of the first connecting rod 341, its second end 3412 moves downward, thereby pushing the shaft member 381 connected to the second end 3412 and sliding it downward along the vertical hole 334 of the fixed base 330 (that is, moving downward along the direction indicated by arrow F4 shown in FIGS. 26 and 27).

[0080] When the position of the first connecting rod 341 moves downward, the first connecting rod 341 pulls the second end 3422 of the second connecting rod 342 and moves downward along the vertical hole 334 (i.e., moves downward along the direction indicated by the arrow F4). As a result, the angle included between the second end 3412 of the first connecting rod 341 and the second end 3422 of the second connecting rod 342 changes. Next, the first end 3421 of the second connecting rod 342 rotates about the second pivot point P2, pulling the second joint 320 and moving it downward. Thereby, the second joint 320 rotates along the direction indicated by the arrow F2 shown in FIGS. 26 and 27 (i.e., the rotation direction of the second joint 320 is opposite to the rotation direction of the first joint 310). During the above-described process, as shown in FIG. 27, the first to fourth pivot points P1 to P4 of the four-bar linkage rotate relative to each other. Therefore, the user can push and rotate the first support member 100 with one hand, drive the second support member 200 to rotate in the reverse direction, and move it closer to the first support member 100 (as shown in FIG. 29), thereby making the folding operation easier and more labor-saving.

[0081] Furthermore, when the first joint 310 and the second joint 320 pivot and approach each other, the first joint 310 and the second joint 320 drive the slide block 380 to slide downward along the slide groove 333. When the first joint 310 and the second joint 320 are completely folded, the slide block 380 slides to the bottom of the slide groove 333 (see FIG. 29). When the slide block 380 slides downward, the slide block 380 drives a lock release device provided on the stroller to release the lock, and the adapter device 1 and the stroller are folded synchronously.

[0082] Naturally, when the second support member 200 receives a force, the first support member 100 and the second support member 200 also pivot relative to each other and are folded.

[0083] As described above, the connection mechanism 300 of the present invention has a first joint 310, a second joint 320, and a lock pin 350. The first joint 310 and the second joint 320 are pivotally connected to each other, and the lock pin 350 is connected between the first joint 310 and the second joint 320. The unlocking operation members 360, 360' can conveniently unlock the connection mechanism 300 to achieve the pivotal operation for folding and unfolding, and the operation is simple and labor-saving. Further, one of the first joint 310 and the second joint 320 is connected to the fixed base 330. The fixed base 330 is configured to be detachably connected to the stroller. Therefore, the connection mechanism 300 can be installed on different strollers according to different requirements. When the connection mechanism 300 is applied to the adapter device 1, the adapter device 1 is convenient and labor-saving enough for folding and unfolding, the operation becomes more convenient, and the storage space occupied by the folded adapter device 1 is reduced. Since the fixed base 330 can be connected to different strollers, the infant accommodation device can be installed on different strollers by the adapter device 1, and the infant accommodation device can be used more flexibly and conveniently.

[0084] The structures of the infant accommodation device and the stroller according to the present invention are well known to those skilled in the art, and thus the description thereof is omitted here.

[0085] Those skilled in the art will readily understand that numerous modifications and variations of the devices and methods can be made while maintaining the teachings of the present invention. Therefore, the above disclosure should be construed as being limited only by the scope of the appended claims.
