This application is based upon and claims priority under 35 U.S.C. 119 from China Patent Application No. 201710028448.8 filed on Jan. 16, 2017, which is hereby specifically incorporated herein by this reference thereto.
The present invention relates to a baby carriage.
The baby carriage is a fairly common tool for families with babies or children today, which prevents the parents from holding the baby all the time and keeps their hands or shoulders free while moving. A conventional baby carriage with double seats is also developed for accommodating two babies.
However, the two seats of the aforementioned baby carriage are fixed and unmovable. Thus, as the baby grows, the spaces of the baby carriage may be insufficient for the baby or the child.
In addition, for families having babies or children, the baby car basket or the child car safety seat are also common tools. But when the baby car basket or the child car safety seat is put on one of the two seats of the baby carriage, the baby car basket or the child car safety seat may extend to the other seat due to the large volume, and thus none of the two seats can accommodate the baby or the child, which is inconvenient.
As a result, the fixed and unmovable seats of the conventional baby carriage cause inconvenience in use, and need to be improved.
It is to be understood that the disclosure of the information in this background is only intended to increase the understanding of the overall background of the present invention and should not be regarded as admitting or in any way hinting that the information constitutes a prior art that is known to those skilled in the art.
To overcome the shortcomings, the present invention provides a baby carriage and a carriage frame thereof to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a baby carriage and a carriage frame thereof that can improve the ride experience for the baby or the child, and improve the adaptability to various situations and reliability.
The carriage frame has a frame body, multiple wheels, a front-seat panel, a rear-seat panel, and at least one rear-seat fixing assembly. The wheels are mounted on the frame body. The front-seat panel is mounted on the frame body. The rear-seat panel is front-and-rear moveably mounted on the frame body, is disposed in back of the front-seat panel, and has at least one clamping recess. The at least one clamping recess is formed in a bottom of the rear-seat panel, is disposed adjacent to one of two transverse sides of the rear-seat panel, and is downwardly disposed around the frame body. The at least one rear-seat fixing assembly corresponds to the at least one clamping recess. Each one of the at least one rear-seat fixing assembly has a seat pivot frame and a seat clamping panel. One of two sides of the seat pivot frame is pivotally connected to the bottom of the rear-seat panel and is disposed adjacent to the corresponding clamping recess. The seat pivot frame is rotatable to be disposed below the corresponding clamping recess. The seat clamping panel is pivotally connected to the other side of the seat pivot frame, and has a seat eccentric part. The seat eccentric part selectively abuts tightly against the transverse side that the corresponding clamping recess is disposed adjacent to, so as to fix the rear-seat panel on the frame body.
As mentioned above, the rear-seat fixing assembly has a seat pivot frame and a seat clamping panel, and the seat clamping panel is mounted with a seat eccentric part. The relative rotation between the seat eccentric part and the seat pivot frame makes the seat eccentric part tightly abut the rear-seat panel to fix the rear-seat panel on the frame body, which is convenient and quick in use, is reliable, and is easy to separate the rear-seat panel from the frame body.
The clamping recess on a bottom of the rear-seat panel also enables the rear-seat panel to move continuously front-and-rear along the frame body in one step. When the rear-seat panel is moved to any suitable position, the rear-seat panel can be quickly and stably fixed on the frame body. When the baby or the child grows up, or when the baby car basket or the child safety seat is put on to be above the front-seat panel, the rear-seat panel can be moved backward to enlarge the space between the front-panel and the rear-seat panel, such that the baby or the child still can sit on the rear-seat panel. The present invention can be adapted to various situations and has various ways of use.

All other embodiments obtained by ordinary skill in the art without making creative work are within the scope of the present invention, based on the following embodiments.
In the following description of this present invention, it is to be understood that the terms “middle”, “transversely”, “vertical”, “front”, “rear”, “left”, “right”, “upper”, “lower”, “top”, “bottom”, “inner”, “outer” and the like are based on the azimuth or positional relationship shown in the drawings. The description, rather than indicating or implying that the device or element referred to must have a specific orientation, is constructed and operated in a particular orientation and therefore cannot be construed as limiting the scope of the present invention.
With reference to FIGS. 1 and 2, a baby carriage in accordance with the present invention comprises a frame body 10, four wheels 16, a folding switch assembly 17, a stand board 71, two stand linking assemblies 72, a front-seat panel 21, a front back-support rod 31, two front back-support fixing assemblies 32, a front back-support switch assembly 33, a rear-seat panel 41, two rear-seat fixing assemblies 42, a rear back-support rod 51, two rear back-support fixing assemblies 52, a rear back-support switch assembly 53, two armrests 61, and two armrest fixing assemblies 62.
With reference to FIGS. 1, 2, and 13, the frame body 10 has two seat rods 11, two armrest rods 12, two front foot rods 13, two rear foot rods 14, and a pushing rod 15. The two seat rods 11 and two armrest rods 12 extend front-and rear. The two seat rods 11 are transversely spaced apart from each other. The two armrest rods 12 are transversely spaced apart from each other, and respectively disposed above the two seat rods 11. Middle parts of the two front foot rods 13 are respectively connected to front ends of the two seat rods 11. Top ends of the two front foot rods 13 are respectively connected to front ends of the two armrest rods 12. Top ends of the two rear foot rods 14 are respectively connected to middle parts of the two armrest rods 12. In a preferred embodiment, the four wheels 16 are respectively mounted on bottom ends of the two front foot rods 13 and bottom ends of the two rear foot rods 14. But the wheels 16 are not limited by the aforementioned, may be three or other numbers in amount, and may be mounted in any other position.
The pushing rod 15 is U-shaped with a downward opening, and is connected to rear ends of the seat rods 11 and rear ends of the armrest rods 12. Two bottom ends of the pushing rod 15 are respectively connected to two middle parts of the two rear foot rods 14. In a preferred embodiment, the front foot rods 13 are pivotally connected to the two seat rods 11 and the two armrest rods 12. The pushing rod 15 is pivotally connected to rear ends of the two seat rods 11, and is pivotally connected to rear ends of the two armrest rods 12. Two top ends of the rear foot rods 14 are respectively and pivotally connected to the two armrest rods 12. Thus, the seat rods 11, the armrest rods 12, the front foot rods 13, and the pushing rod 15 form a four-bar linkage to be folded, and the folding can be proceeded with the folding switch assembly 17.
With reference to FIGS. 2 to 4, two receiving recesses 141 are respectively downwardly formed in the two middle parts of the two rear foot rods 14. The folding switch assembly 17 is mounted on a middle part of the pushing rod 15, and has two fixing units 171, two fixing unit resilient elements 172, a folding switch 173, and two folding ropes 174. The two fixing units 171 are up-and-down movably mounted in the pushing rod 15, and are selectively downwardly mounted in the two receiving recesses 141 of the two rear foot rods 14. The two fixing unit resilient elements 172 are mounted in the pushing rod 15, and respectively push the two fixing units 171 into the corresponding receiving recess 141. Two ends of each folding rope 174 are respectively connected to the folding switch 173 and one of the fixing units 171. In a preferred embodiment, the folding rope 174 is preferably, but not limited to, a steel rope. The folding switch 173 can pull up the two fixing units 171 via the two folding ropes 174.
Therefore, when the seat rods 11, the armrest rods 12, the front foot rods 13, and the pushing rod 15 are expanded for use, the two fixing units 171 on the pushing rod 15 are mounted in the receiving recesses 141 of the rear foot rods 14 to keep the frame body 10 in the expanded situation. To fold the frame body 10, the folding switch 173 is pressed to separate the fixing units 171 from the receiving recesses 141. At this time, the pushing rod 15 can be pushed forward to fold the frame body 10.
With reference to FIGS. 2, 5, 6, and 17, the stand board 71 is mounted between the two rear foot rods 14 and disposed between the two wheels 16 on the two rear foot rods 14. The two stand linking assemblies 72 are mounted on two sides of the stand board 71. Each stand linking assembly 72 is connected to the rear foot rod 14 and the seat rod 11 that are at the same side. When the frame body 10 is folded, the stand linking assemblies 72 rotate the stand board 71 to be folded. When the frame body 10 is expanded, the stand linking assemblies 72 also rotate the stand board 71 to be horizontally expanded.
In a preferred embodiment, each stand linking assembly 72 has a driving element 721 and a linking rod 722. A top end of the driving element 721 is pivotally connected to the rear end of the seat rod 11. A bottom end of the driving element 721 is pivotally connected to the rear foot rod 14 via a first pin 723. A curved guiding hole 7211 is formed through the driving element 721. A second pin 724 is mounted through the linking rod 722, and is mounted in the curved guiding hole 7211. A linking slide hole 7221 is formed through a top end of the linking rod 722, and is disposed below the second pin 724. The first pin 723, which is pivotally connected to the driving element 721 and the rear foot rod 14, is mounted through the linking slide hole 7221. A bottom end of the linking rod 722 is pivotally connected to the stand board 71.
As such, to fold the frame body 10, the pushing rod 15 is pushed forward to move back the seat rods 11. Then, the back movements of the seat rod 11 make the driving element 721 rotated backward, and the first pin 723 is the rotating axis. The driving element 721 downwardly pushes the linking rod 722 via the curved guiding hole 7211 and the second pin 724. Finally, the downward movement of the linking rod 722 makes the stand linking assembly 72 simultaneously rotate the stand board 71 to be vertical, thereby achieving the folding.
With reference to FIG. 17, in another preferred embodiment, the stand board 71 is further pivotally connected with a stand tube 73. When the frame body 10 is folded and the baby carriage frame is standing, the stand tube 73 is simultaneously rotated by the stand linking assemblies 72 and the stand board 71 to abut on the ground to keep the baby carriage frame in a standing position.
With reference to FIGS. 1, 2, 7, and 8, the front-seat panel 21 and the rear-seat panel 41 are mounted on the frame body 10, are mounted between the two seat rods 11, and are spaced apart from each other.
The rear-seat panel 41 is front-and-rear moveable relative to the frame body 10, thereby adjusting a distance between the front-seat panel 21 and the rear-seat panel 41 to adapt to the babies and the children of different body sizes.
Furthermore, the rear-seat panel 41 is detachable from the frame body 10, such that the frame body 10 may have larger space to accommodate various items when removing the rear-seat panel 41. The seat space of the present invention can be adjusted, and has multiple functions.
To be specific, a bottom of the rear-seat panel 41 is formed with two clamping recesses 411. The two clamping recesses 411 are respectively disposed adjacent to two transverse sides of the rear-seat panel 41, and are respectively downwardly disposed around the two seat rods 11 of the frame body 10.
The two rear-seat fixing assemblies 42 are respectively mounted on the transverse sides of the rear-seat panel 41, are connected to the frame body 10, and can fix the rear-seat panel 41 on the frame body 10. In a preferred embodiment, the two rear-seat fixing assemblies 42 are respectively correspond to the two clamping recesses 411. Each rear-seat fixing assembly 42 has a seat pivot frame 421 and a seat clamping panel 422. A side of the seat pivot frame 421 is pivotally connected to the bottom of the rear-seat panel 41. The seat pivot frame 421 is disposed adjacent to the corresponding clamping recess 411, and the seat pivot frame 421 is rotatable to be disposed below the corresponding clamping recess 411.
With reference to FIGS. 7 and 8, the seat clamping panel 422 is pivotally connected to the other side of the seat pivot frame 421, and the seat clamping panel 422 is formed with a seat eccentric part 4221. A head of the seat clamping panel 422 is roughly round. A rotating shaft is eccentrically mounted through the head of the seat clamping panel 422. That is, a distance between a periphery of the head and the rotating shaft is not constant. When the seat clamping panel 422 is rotated to make the seat eccentric part 4221 abut against the transverse side of the rear-seat panel 41, the distance between the rotating shaft and the transverse side of the rear-seat panel 41 is the largest to make the seat eccentric part 4221 tightly abut the transverse side of the rear-seat panel 41, such that the rear-seat panel 41 is fixed on the frame body 10.
The relative rotation between the seat eccentric part 4221 and the seat pivot frame 421 makes the seat eccentric part 4221 tightly abut the rear-seat panel 41 to fix the rear-seat panel 41 on the frame body 10, which is convenient and quick in use, is reliable, and is easy to separate the rear-seat panel 41 from the frame body 10. The clamping recesses 411 on the bottom of the rear-seat panel 41 enable the rear-seat panel 41 to move continuously front-and-rear along the frame body 10 in one step. When the rear-seat panel 41 is moved to any suitable position, the rear-seat panel 41 can be quickly and stably fixed on the frame body 10.
Two rear-seat resilient panels 412 are respectively mounted on the two transverse sides of the rear-seat panel 41, and each rear-seat resilient panel 412 has a curved concave surface 4121 on an outer wall of the rear-seat resilient panel 412.
To be specific, when the seat pivot frame 421 is rotated to be below the clamping recess 411, the seat clamping panel 422 can be rotated upward to make the seat eccentric part 4221 tightly abut the curved concave surface 4121 of the rear-seat resilient panel 412 of the rear-seat panel 41, such that two side walls of the clamping recess 411 tightly clamp the seat rod 11 to fix a relative position between the rear-seat panel 41 and the frame body 10. On the contrary, to detach the rear-seat panel 41, the seat clamping panel 422 is rotated reversely to make the seat eccentric part 4221 not abut the rear-seat resilient panel 412, and then the rear-seat panel 41 is detached upward from the seat rods 11.
With reference to FIGS. 2 and 9, the rear back-support rod 51 is tiltably and detachably mounted on the two seat rods 11 of the frame body 10. The two rear back-support fixing assemblies 52 are respectively mounted between the rear back-support rod 51 and the two seat rods 11 to fix the rear back-support rod 51 on the two seat rods 11.
Each rear back-support fixing assembly 52 has a channel unit 521, a positioning pin 522, a moving element 523, and a positioning pin resilient element 524. The two channel units 521 of the two rear back-support fixing assemblies 52 are respectively mounted securely on the two seat rods 11. A channel recess 5211 and multiple positioning parts 5212 are formed in a side surface of the channel unit 521. The positioning parts 5212 are spaced apart from each other, are disposed below the channel recess 5211, and communicate with the channel recess 5211. The rear back-support rod 51 is pivotally connected to a side surface that forms the channel recess 5211 of the channel unit 521. The positioning pin 522 is up-and-down movably mounted through the rear back-support rod 51, and is up-and-down movably mounted in the channel recess 5211. To be specific, the positioning pin 522 is movable in the channel recess 5211, and may be moved into one of the positioning parts 5212. The positioning pin resilient elements 524 are mounted in the rear back-support rod 51, and downwardly push the positioning pins 522 to make the positioning pins 522 move into the positioning part 5212.
To be specific, the positioning pin resilient element 524 may be a spring. An end of the spring is connected to the moving element 523, and the other end of the spring is connected to a shaft between the rear back-support rod 51 and the seat rod 11. The rear back-support rod 51 is formed with an elongated hole, and the moving element 523 corresponds in position to the elongated hole. Thus, the positioning pin 522 is up-and-down moveable in the elongated hole, and the positioning pin 522 is limited in the corresponding positioning part 5212 by the positioning pin resilient element 524.
The rear back-support switch assembly 53 is for controlling the two rear back-support fixing assemblies 52. The rear back-support switch assembly 53 is mounted on the rear back-support rod 51 and has a rear back-support switch 531 and a rear back-support rod rope (not shown). Two ends of the rear back-support rod rope are respectively connected to the rear back-support switch 531 and the positioning pin 522 of one of the rear back-support fixing assemblies 52. In a preferred embodiment, the rear back-support rod rope is preferably, but not limited to, a steel rope. The rear back-support switch 531 can pull up the two positioning pins 522 via the two rear back-support rod ropes.
Normally, the positioning pin 522 engages in one of the positioning parts 5212, thereby fixing the relative angle between the rear back-support rod 51 and the seat rods 11. To adjust the angle, the rear back-support switch 531 is pressed to make the positioning pin 522 detached upward from the positioning part 5212.
With reference to FIG. 9, in addition, each seat rod 11 is mounted with a connecting seat 18, and the connecting seat 18 has a pressing protrusion 181. The channel unit 521 of the rear back-support fixing assembly 52 is downwardly mounted around the connecting seat 18, and the channel unit 521 has an opening for the pressing protrusion 181 to protrude out. Therefore, normally, the pressing protrusion 181 engages in the opening of the channel unit 521, and thus the rear back-support rod 51 and rear back-support fixing assembly 52 are fixed on the seat rods 11. To separate the rear back-support rod 51, the pressing protrusion 181 of the connecting seat 18 is pressed to be inside of the opening, and the rear back-support rod 51 and the rear back-support fixing assembly 52 are upward detachable from the seat rods 11 and the connecting seats 18.
In a preferred embodiment, the front back-support rod 31 is tiltably and detachably mounted on the two seat rods 11 of the frame body 10. The two front back-support fixing assemblies 32 and the front back-support switch assembly 33 are substantially the same in structure as the two rear back-support fixing assemblies 52 and the rear back-support switch assembly 53, and thus are not repeated in the description.
With reference to FIGS. 2, 10, and 11, the two armrests 61 are up-and-down movably and detachably mounted on the pushing rod 15. In a preferred embodiment, the armrest 61 is U-shaped, and two ends of each armrest 61 are respectively mounted with a surrounding element 611. The surrounding element 611 is mounted around the pushing rod 15 by a backward opening. In a preferred embodiment, a transverse outer side of the surrounding element 611 is mounted with a surrounding element resilient panel 6111. An outer wall of the surrounding element resilient panel 6111 is formed with a curved concave surface 6112.
The two armrest fixing assemblies 62 are respectively mounted on the two armrests 61, are connected to the pushing rod 15, and respectively fix the two armrests 61 on the pushing rod 15. In a preferred embodiment, each armrest fixing assembly 62 corresponds to the two surrounding elements 611 on the same armrest 61. The armrest fixing assembly 62 has an armrest pivot frame 621 and an armrest clamping panel 622. One of two sides of each armrest pivot frame 621 is pivotally connected to the corresponding end of the armrest 61, and the armrest pivot frame 621 is rotatable to surround the pushing rod 15 with the corresponding surrounding element 611.
With reference to FIGS. 10, and 11, the armrest clamping panel 622 is pivotally connected to the other side of the armrest pivot frame 621, and the armrest clamping panel 622 is formed with an armrest eccentric part 6221. A head of the armrest clamping panel 622 is roughly round. A rotating shaft is eccentrically mounted through the head of the armrest clamping panel 622. That is, a distance between a periphery of the head and the rotating shaft is not constant. When the armrest clamping panel 622 is rotated to make the armrest eccentric part 6221 abut against the transverse side of the surrounding element resilient panel 6111, the distance between the rotating shaft and the transverse side of the surrounding element resilient panel 6111 is the largest to make the armrest eccentric part 6221 tightly abut the transverse side of the surrounding element resilient panel 6111, such that the armrest 61 is fixed on the frame body 10.
To be specific, when the armrest pivot frame 621 is rotated to be in back of the surrounding element 611, the armrest clamping panel 622 can be rotated forward to make the armrest eccentric part 6221 tightly abut the curved concave surface 6112 of the surrounding element resilient panel 6111 of the surrounding element 611, such that the two side walls of the surrounding element 611 tightly clamp the pushing rod 15 to fix a relative position between the armrest 61 and the pushing rod 15. On the contrary, to detach the armrest 61, the armrest clamping panel 622 is rotated reversely to make the armrest clamping panel 622 not abut the surrounding element resilient panel 6111, and then the armrest 61 can be detached forward from the pushing rod 15.
With reference to FIG. 14, in addition, in a preferred embodiment, the pushing rod 15 is same with the armrest rod 12 in cross section. Thus, the armrest 61 and the armrest fixing assembly 62 may be mounted on the armrest rod 12, thereby facilitating convenience in use and increasing various ways of use.
When the present invention is in use, the rear-seat panel 41 is front-and-rear moveable to adjust the space between the front-seat panel 21 and the rear-seat panel 41, thereby fitting babies and children of different body sizes and ages.
With reference to FIG. 12, when the rear-seat panel 41 is moved backward relative to the two seat rods 11 and the front back-support rod 31 is detached, the space corresponding to the front-seat panel 21 can accommodate objects such as a baby car basket or a child car safety seat. At the same time, the space corresponding to the rear-seat panel 41 is still large enough for the baby or the child to be seated therein.
On the contrary, when the rear back-support rod 51 is detached, the space corresponding to the rear-seat panel 41 also can accommodate the baby car basket or the child car safety seat. At this time, the space corresponding to the front-seat panel 21 is still large enough for the baby or the child to be seated therein.
With reference to FIGS. 13, and 14, when the rear-seat panel 41 is moved forward relative to the two seat rods 11 and the rear back-support rod 51 is detached, an elder or bigger child can stand on the stand board 71 and hold the armrests 61. The armrest 61 can be moved upward or downward on the pushing rod 15 or can be moved front-and-rear on the armrest rods 12 to be grabbed conveniently.
With reference to FIGS. 15, and 16, finally, the rear-seat panel 41a also can be detached when in need for a larger space. For example as shown in FIG. 15, a hanging connector 111 is mounted on a bottom of the seat rod 11 to hang a large shopping bag with a top opening or the shopping basket below the seat rod 11.
To be specific, a belt crosses a bottom of the shopping basket and two ends of the belt respectively extend above two sides of the shopping basket. The two ends of the belt are respectively mounted with a connecting part. The connecting part is 8-shaped and has an upper and smaller first circle and a lower and larger second circle. The hanging connector 111 comprises a tube and a protrusion. The protrusion is formed on an outer end of the tube, and the protrusion is larger than the tube in diameter. The first circle of the connecting part is substantially the same as the tube of the hanging connector 111 in diameter. The second circle is substantially the same as the protrusion in diameter. When installed, the connecting part of the belt engages with the hanging connector 111. The second circle is mounted through the protrusion and the tube in sequence, and then the hanging connector falls down by the gravity to make the first circle mounted around the tube. At this time, the protrusion abuts the first circle to prevent the connecting part from detaching from the hanging connector.
In addition, in the abovementioned figures, the baby car basket and the child safety seat are mounted on the space corresponding to the front-seat panel 21. But the baby car basket and the child safety seat also may be mounted on the space corresponding to the rear-seat panel 41. Therefore, the baby or the child also can sit on the front-seat panel 21. Moreover, when the baby or the child sits on the rear-seat panel 41, he can face forward (with the rear back-support rod 51 installed) or face backward (with the rear back-support rod 51 uninstalled).
