Description

Technical Field

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

Background Art

[0002] Various types of baby carriages (e.g., strollers, safety seats, bassinets , cribs, etc.) are widely used in households with infants. For example, a bassinet is 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 braking or collisions between vehicles, and can protect infants. A bassinet can be carried after getting out of the car or when going out , so it is convenient for carrying infants. A bassinet can also be used alone at home , enhancing the convenience of using the bassinet. To reduce the burden on caregivers when going out, bassinets used in special strollers have been developed to facilitate carrying infants. Since this type of bassinet can only be used in special strollers and not in other baby carriages, the use of this bassinet is limited

[0003] and not yet fully convenient. Therefore, there is a need to provide an adapter device that allows a bassinet to be used with various baby carriages and reduces storage space .

The shaft member 354 is disposed in the longitudinal hole 353 of the connection head 352 and is connected to the side wall of the engagement groove 365 (as shown in FIGS. 16 and 17). When the unlocking operation member 360 rotates along the direction of arrow F3 or in the direction opposite to arrow F3 shown in FIG. 16, the locking pin 350 is slide-driven by the interaction between the shaft member 354 and the longitudinal hole 353. .

[0057] Of course, the unlocking operation member 360 and the return member 370 are not limited to the arrangement of this embodiment and may be realized by other structures shown below. As shown in FIGS. 3, 4, 7, 8, and 10 to 14, the connection mechanism 300 further includes a slide

[0058] 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.

Further, as shown in FIG. 11, a breach 32 4 is formed on 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 above 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 it along the direction of arrow F4 shown in FIG. 3). When the first joint 310 and the second joint 320 are completely folded up, (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 arranged on the stroller to unlock the lock and the adapter device 1 and the stroller are folded synchronously. 333.

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 bassinet to the adapter device 1, the adapter device 1 needs to be deployed first. At this time, the first support member 100 and the second support member 200 extend in opposite directions as shown in FIGS. 1 and 3. The adapter device 1 can be placed directly on the ground or the platform beam, and then the bassinet can be engaged with the adapter device 1. The connection between the bassinet and the adapter device 1 is well known to those skilled in the art. The adapter device 1 can prevent the bassinet from shaking, so that the infants sitting in the bassinet feel more comfortable. Furthermore, the adapter device 1 can be engaged with the stroller. That is, the fixed base 330 can be engaged with the engagement mechanism of the stroller to install the bassinet on the stroller.

[0063] When the adapter device 1 is not needed, the bassinet, the adapter device 1 and the stroller can be removed and folded from each other, or the adapter device 1 can be directly folded together with the stroller. Specifically, as shown in FIGS. 1 to 18, the tension member 400 can be pulled upward so that the two connection mechanisms 30 0's unlocking operation members 360 are pulled and pivot 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 pressing the first support member 100 and rotating it by a predetermined angle, the tension member 400 is released. The unlocking operation member 360 returns by the return member 370, and the locking pin 350 is driven to slide toward the second joint 32 0, and as shown in FIGS. 6 and 8, the locking pin 35 0 slides into the locking hole 322 of the second joint 320 to lock, and the first support member 100 and the second support member 200 are folded. 0 slides into the locking hole 322 of the second joint 320 to lock, and the first support member 100 and the second support member 200 are folded. 0 slides into the locking hole 322 of the second joint 320 to lock, and the first support member 100 and the second support member 200 are folded. 0 engages with the restraint groove 323.

[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 means of 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, there is no need 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 above-described 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 movable to the first joint 310 by means of the shaft 3611'. ​​​​​​​​​​​​ is pivotally connected. 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 31 0. The operation part 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 projecting support column 366 protruding from the side surface, and the first joint 310 has a second projecting support column 315 corresponding to the first projecting support column 366. Both ends of the return member 370' are respectively sleeved on the first projecting support column 36 6 and the second projecting support column 315, and abut against 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, driving the unlocking operation member 360' to return (that is, driving 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 previous embodiment, so the repeated description is 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 an 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 cuts across 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

[0071] 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. As shown in FIGS. 23 to 29, in the third embodiment of the present invention, the difference between the adapter device 1 and the aforementioned first

[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, and 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 point 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 more labor-saving. 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. 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. Here, 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. 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 point P3. Here, 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 point P3. 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. Here, 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. Here, 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. Here, 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 more 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. Here, 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, a slide hole 326 is formed on the second joint 320 and penetrates through it. 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 from it. The support column 316 is slidably arranged within the slide hole 326. The support column 316 extends towards the fixed base 330. As shown in FIG. 24, the support column 316 is pivotally connected to the first end 3411 of the first connecting rod 341. 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 3 81. The shaft member 381 is slidably arranged within the vertical hole 334 of the fixed base 330 and is connected to the slide block 3

[0075] 80. Therefore, when the first joint 310 and the second joint 3 20 pivot towards 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-bar linkage mechanism achieves connection when the first joint 310 and the second joint 3 20 are folded, and further, by driving the slide block 380 to slide downward synchronously, the connection structure between the first joint 31 0 and the second joint 320 is greatly simplified. Specifically, a slide hole 326 is formed on the second joint 320 and penetrates through it. 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 from it. The support column 316 is slidably arranged within the slide hole 326. The support column 316 extends towards the fixed base 330. As shown in FIG. 24, the support column 316 is pivotally connected to the first end 3411 of the first connecting rod 341. 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 3

[0076] In this embodiment, the slide groove 333 of the fixed base 330 is perpendicular to the central axis L of the fixed base 330, and the vertical hole 334 of the slide groove 333 is also perpendicular to the central axis L. It is.

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

[0078] Referring to FIGS. 23 to 29 again, 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 operating 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 fold. The specific operation is as follows. When the first support member 100 is pushed and rotated along the direction of arrow F1 shown in FIG. 23,

[0079] 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 in 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 pivoting 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 3 moves the first end 3411 of the first connecting rod 341 along the slide hole 326 (i.e., the first end 3411 of the first connecting rod 341 rotates around the fourth pivoting 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 3 drives the first end 3411 of the first connecting rod 341 to slide along the slide hole 326 (i.e., the first end 3411 of the first connecting rod 341 rotates around the fourth pivoting 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 3 412 moves downward, thereby pushing the shaft member 381 connected to the second end portion 3412 and sliding downward along the vertical hole 334 of the fixed base 330 (i.e., moving downward along the direction indicated by the arrow F4 shown in FIGS. 26 and 27). When the position of the first connecting rod 341 moves downward, the first connecting rod 341 pulls the second end portion 3422 of the second connecting rod 342 and moves downward along the vertical hole 334

[0080] (i.e., moving downward along the direction indicated by the arrow F4). As a result, the angle included between the second end portion 3412 of the first connecting rod 341 and the second end portion 3422 of the second connecting rod 342 changes. Next, the first end portion 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 close to the first support member 100 (as shown in FIG. 29), thereby making the folding operation easier and more labor-saving. (i.e., moving downward along the direction indicated by the arrow F4 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. (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. (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 close to the first support member 100 (as shown in FIG. 29), thereby making the folding operation easier and more labor-saving. (i.e., moving downward along the direction indicated by the arrow F4 shown in FIGS. 26 and 27).

[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 fully 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 the unlocking device provided on the stroller to unlock the lock, and the adapter device 1 and the stroller are folded synchronously. Of course, when the second support member 200 receives a force, the first support member 100 and the

[0082] second support member 200 also pivot relative to each other and are folded. As described above, the connection mechanism 300 of the present invention has a first joint 310, a second joint

[0083] 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 31 0 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 and 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 and can be installed on different strollers according to different requirements. When the connection mechanism 300 is applied to the adapter device 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 baby carriages, the infant accommodation device can be installed on different baby carriages 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 baby carriage according to the present invention are well-known to those skilled in the art, so the description is omitted here.

[0085] Those skilled in the art will readily understand that numerous modifications and changes to the device and method 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 patent claims. ​
