Abstract
Description
[0001] This application is a divisional application of the invention patent application of Mingmen Switzerland Co., Ltd. (the application date is January 5, 2021, the application number is 202110015379.3, and the invention title is "Baby Carrier and Its Anti-Misuse Height Adjustment Mechanism"). Technical Field
[0002] The present invention relates to a baby product, and in particular to a baby carrier and an anti-misuse height adjustment mechanism. Background Art
[0003] Baby strollers have long been widely used in families with children. This type of baby stroller usually has a frame and a sleeping box or seat that can be selectively installed on the frame. To facilitate the use of the baby stroller, some baby strollers are also provided with a seat height adjustment mechanism located between the frame and the seat. The existing seat height adjustment mechanism includes an operating mechanism and a clamping mechanism. By operating the operating mechanism, the clamping mechanism is controlled to unlock, so as to adjust the height of the seat relative to the frame. However, the current seat height adjustment mechanism allows the seat to be adjusted immediately after the operating mechanism is operated, so the height adjustment of the seat is too casual, and the seat may slide off the frame when there is accidental contact or improper operation.
[0004] Therefore, there is an urgent need for a baby carrier and its anti-misuse height adjustment mechanism to overcome the above defects. Summary of the Invention
[0005] The purpose of the present invention is to provide an anti-misuse height adjustment mechanism that can avoid accidental unlocking caused by accidental contact.
[0006] Another purpose of the present invention is to provide a baby carrier that can avoid accidental unlocking caused by accidental contact.
[0007] To achieve the above purpose, the anti-misuse height adjustment mechanism of the present invention is provided on a baby carrier. The baby carrier includes a carrier skeleton and a carrier body. The anti-misuse height adjustment mechanism includes a clamping member, an elastic member, a card-releasing operation member, and a fixed seat for assembling and connecting with the carrier body. The fixed seat is slidably disposed on the carrier skeleton and slides and adjusts relative to the carrier skeleton. The carrier skeleton has at least two stage mating and clamping portions. The clamping member is movably assembled on the fixed seat and selectively engages with any stage mating and clamping portion. The card-releasing operation member is movably installed on the fixed seat. The card-releasing operation member is also linked with the clamping member through the elastic member, and the force that causes the elastic member to generate elastic deformation when the card-releasing operation member releases the card is less than the resistance that blocks the clamping member from performing the card-releasing movement generated by the fixed seat and the carrier body on the fixed seat.
[0008] Preferably, the card-releasing operation member is telescopically hinged to the fixed seat, and when the card-releasing operation member is pressed, it rotates and retracts into the fixed seat to release the card.
[0009] Preferably, the anti-misuse height adjustment mechanism of the present invention further includes a sliding member slidably disposed in the fixed seat. The sliding member is blocked and connected to the elastic member. During the card release operation, the card release operating member pushes the sliding member to slide upward, and the upward-sliding sliding member pushes the elastic member to elastically deform.
[0010] Preferably, the card release operating member is provided with a pushing protrusion protruding outward. A positioning notch is defined between the pushing protrusion and the card release operating member. The sliding member is disposed in the positioning notch and is in blocking cooperation with the card release operating member. The pressed card release operating member rotates and retracts into the fixed seat, so that the pushing protrusion pushes the sliding member to slide upward.
[0011] Preferably, the bottom of the sliding member is provided with a pushed inclined surface arranged obliquely with respect to the sliding direction of the sliding member. The pushing protrusion abuts against the pushed inclined surface of the sliding member.
[0012] Preferably, the anti-misuse height adjustment mechanism of the present invention further includes a connecting member. The engaging member is installed at the first end of the connecting member. The sliding member is slidably disposed at the second end of the connecting member. The elastic member is disposed between the sliding member and the connecting member.
[0013] Preferably, the sliding member has an installation cavity. The second end of the connecting member is movably disposed in the installation cavity. The elastic member is disposed in the installation cavity.
[0014] Preferably, a blocking protrusion is provided at the end of the second end of the connecting member. The first end of the elastic member abuts against the blocking protrusion. The second end of the elastic member abuts against the bottom wall of the installation cavity in the sliding member.
[0015] Preferably, the engaging member includes an engaging portion and a pivoting portion. The first end of the pivoting portion is pivotally connected to the first end of the connecting member. The first end of the engaging portion is installed at the second end of the pivoting portion and is pivotally connected to the fixed seat. The pivoting portion is pivotally arranged on the connecting member.
[0016] Preferably, the engaging member further includes a pivot shaft. The first end of the pivot shaft is rotatably assembled in the fixed seat. The second end of the pivoting portion is installed at the second end of the pivot shaft. The first end of the engaging portion is installed at a position between the two ends of the pivot shaft.
[0017] Preferably, the engaging portion is a block-shaped member whose width gradually increases from its first end to its second end. An insertion inclined surface is provided on the bottom surface of the second end of the engaging portion.
[0018] Preferably, the anti-misuse height adjustment mechanism of the present invention further includes a card engaging and resetting member disposed between the fixed seat and the connecting member. The card engaging and resetting member always has a tendency to drive the connecting member to slide downward.
[0019] Preferably, the connecting member is a rod-shaped member. The sliding direction of the sliding member is the same as the sliding direction of the connecting member.
[0020] Preferably, a slide rail is installed on the vehicle frame, the fixed seat is slidably assembled on the slide rail, and all the stage matching card parts are arranged on the slide rail at intervals from each other.
[0021] Preferably, the stage matching card part is a slot structure.
[0022] Preferably, the upper side wall of the stage matching card part is a sliding inclined surface arranged obliquely inward from top to bottom.
[0023] Preferably, the fixed seat includes a long handle part and a support seat part installed at the lower end of the long handle part. The card releasing operating part is arranged inside the upper end of the long handle part. A collar is installed at the upper end of the long handle part, and the collar is slidably sleeved on the vehicle frame.
[0024] To achieve the above object, the baby carrier of the present invention includes a vehicle frame, a vehicle body and the above anti-misuse height adjustment mechanism, and the fixed seat is assembled on the vehicle body.
[0025] Preferably, the vehicle frame is a pushchair frame or a baby dining chair frame.
[0026] Preferably, the vehicle body is a baby sleeping box, a safety seat or a baby dining chair.
[0027] Compared with the prior art, the anti-misuse height adjustment mechanism of the present invention includes a clamping member, an elastic member, a card releasing operating member, a fixed seat, a sliding member slidably arranged in the fixed seat and a connecting member. The fixed seat is slidably arranged on the vehicle frame and slides relative to the vehicle frame for adjustment. The vehicle frame has at least two stage matching card parts. The clamping member is movably assembled on the fixed seat and selectively engages with any stage matching card part. The card releasing operating member is movably installed on the fixed seat. The card releasing operating member is also linked with the clamping member through the elastic member, and the force that the card releasing operating member drives the elastic member to generate elastic deformation during the card releasing process is less than the resistance that the fixed seat and the vehicle body on the fixed seat generate to block the clamping member from performing the card releasing movement. Therefore, even after the card releasing operating member is operated to release the card, since the vehicle body does not move upward, there is a lack of a force to lift the vehicle body to balance the resistance that the fixed seat and the vehicle body generate to block the clamping member from performing the card releasing movement. Therefore, the clamping member always remains engaged with a stage matching card part, the vehicle body is locked on the vehicle frame, and the vehicle body cannot be adjusted in height. Therefore, during the height adjustment process of the vehicle body, the vehicle body must be lifted upward to unlock the anti-misuse height adjustment mechanism. Therefore, accidental unlocking caused by accidental contact can be effectively avoided.
[0028] It can be understood that since the baby carrier of the present invention includes a vehicle frame, a vehicle body and an anti-misuse height adjustment mechanism, the baby carrier of the present invention can avoid accidental unlocking of the vehicle body on the vehicle frame caused by accidental contact, effectively ensuring the use safety.

Detailed implementation manners
[0040] In order to elaborate in detail the technical content and structural features of the present invention, the following further description is made in conjunction with the implementation manners and with reference to the drawings.
[0041] As Figure 1 and Figure 2 shown, the baby carrier 100 of the present invention includes a carrier frame 10, a carrier body 20 and a misuse-preventing height adjustment mechanism 30. The fixed seat 34 in the misuse-preventing height adjustment mechanism 30 described below is assembled on the carrier body 20. The fixed seat 34 is slidably disposed on the carrier frame 10 and is slidably adjusted relative to the carrier frame 10. When adjusting the height of the carrier body 20, it is necessary to lift the carrier body 20 upward to perform the height adjustment, avoiding misoperation of the height adjustment of the carrier body 20. Thus, the baby carrier 100 of the present invention can avoid accidental unlocking of the carrier body 20 on the carrier frame 10 due to accidental contact, effectively ensuring the use safety. For example, the carrier body 20 is mainly a device for supporting infants and young children, such as a baby sleeping box, a safety seat or a baby dining chair, but not limited thereto. The carrier frame 10 is mainly divided into two categories. One category is the carrier frame 10 that can provide a moving function, such as a pushchair frame, and the other category is the carrier frame 10 that can provide a fixed support function, such as a baby dining chair frame, but not limited thereto. In summary, those skilled in the art can connect the carrier body 20 to the existing carrier frame 10 according to the actual needs without any creative labor for combined use according to the actual situation requirements, so it will not be described in detail herein. The following will further elaborate on the misuse-preventing height adjustment mechanism 30 of the present invention with reference to Figures 2 to 11 make a further detailed description of the misuse-preventing height adjustment mechanism 30 of the present invention:
[0042] As Figures 2 to 8As shown in the figure, the anti-misuse height adjustment mechanism 30 includes a clamping member 31, an elastic member 32, a release operation member 33, a fixed seat 34, a sliding member 35 slidably disposed within the fixed seat 34, and a connecting member 36. The fixed seat 34 is slidably disposed on the vehicle frame 10 and is slidably adjusted relative to the vehicle frame 10. The vehicle frame 10 has at least two stage mating and clamping portions 11. The clamping member 31 is movably assembled on the fixed seat 34 and selectively engages with any one of the stage mating and clamping portions 11. The release operation member 33 is movably mounted on the fixed seat 34. The release operation member 33 is also linked to the clamping member 31 through the elastic member 32. Moreover, the force that causes the elastic member 32 to generate elastic deformation when the release operation member 33 performs the release operation is less than the resistance that blocks the clamping member 31 from performing the release movement generated by the fixed seat 34 and the vehicle body 20 on the fixed seat 34. Therefore, even after the release operation member 33 is operated to release the lock, since the vehicle body 20 is not adjusted upward, there is a lack of a force to lift the vehicle body 20 to balance the resistance that blocks the clamping member 31 from performing the release movement generated by the fixed seat 34 and the vehicle body 20. Thus, the clamping member 31 always remains engaged with one of the stage mating and clamping portions 11, and the vehicle body 20 remains locked on the vehicle frame 10, and the vehicle body 20 cannot be adjusted in height. Therefore, during the height adjustment process of the vehicle body 20, it is necessary to lift the vehicle body 20 upward to release the lock of the anti-misuse height adjustment mechanism 30. Therefore, accidental unlocking caused by accidental contact can be effectively avoided. For example, the elastic member 32 is a compression spring. Of course, according to actual needs, the elastic member 32 can also be provided as a pair of magnetic members with opposite polarities, where the positive member is installed on the connecting member 36 and the negative member is installed on the sliding member 35. Therefore, it is not limited thereto. Specifically, the sliding member 35 is blockingly connected to the elastic member 32. During the release operation, the release operation member 33 pushes the sliding member 35 to slide upward, and the upward-sliding sliding member 35 pushes the elastic member 32 to elastically deform, so as to facilitate driving the elastic deformation of the elastic member 32. More specifically, the clamping member 31 is installed at the first end of the connecting member 36, the sliding member 35 is slidably disposed at the second end of the connecting member 36, and the elastic member 32 is disposed between the sliding member 35 and the connecting member 36. By means of the setting of the connecting member 36, the linkage structure between the operation member 33 and the clamping member 31 is simplified. In order to facilitate the reset of the clamping member 31 to engage with the stage mating and clamping portions 11 on the vehicle frame 10, the anti-misuse height adjustment mechanism 30 further includes a clamping and resetting member 37 disposed between the fixed seat 34 and the connecting member 36. The clamping and resetting member 37 always has a tendency to drive the connecting member 36 to slide downward.
[0043] As Figures 4 to 8As shown, the card releasing operating member 33 is telescopically hinged to the fixed seat 34. When the card releasing operating member 33 is pressed, it rotates and retracts into the fixed seat 34 to release the card, so the operation of the card releasing operating member 33 is simple. Specifically, the card releasing operating member 33 is provided with a pushing protrusion 331 protruding outward. A positioning notch 332 is defined between the pushing protrusion 331 and the card releasing operating member 33. The sliding member 35 is arranged in the positioning notch 332 and is in blocking cooperation with the card releasing operating member 33. When the card releasing operating member 33 is pressed, it rotates and retracts into the fixed seat 34, so that the pushing protrusion 331 pushes the sliding member 35 to slide upward. Therefore, the linkage structure between the card releasing operating member 33 and the sliding member 35 is simple and easy to implement, which is beneficial to reducing the production difficulty and production cost. More specifically, the bottom of the sliding member 35 is provided with a pushed inclined surface 351 arranged obliquely with respect to the sliding direction of the sliding member 35. The pushing protrusion 331 abuts against the pushed inclined surface 351 of the sliding member 35. The arrangement of the pushed inclined surface 351 on the sliding member 35 can facilitate the card releasing operating member 33 to push the sliding member 35 to slide.
[0044] As Figures 5 to 8 shown, the sliding member 35 has an installation cavity 352. The second end of the connecting member 36 is movably arranged in the installation cavity 352. The elastic member 32 is arranged in the installation cavity 352. The cooperation between the installation cavity 352 of the sliding member 35 and the connecting member 36 enables the sliding member 35 to slide smoothly on the connecting member 36, and is also beneficial to hiding the elastic member 32 and further simplifying the structure. Specifically, the end of the second end of the connecting member 36 is provided with a blocking protrusion 361. The first end of the elastic member 32 abuts against the blocking protrusion 361, and the second end of the elastic member 32 abuts against the bottom wall of the installation cavity 352 in the sliding member 35, so that the elastic member 32 is stably installed in the installation cavity 352.
[0045] As Figures 5 to 9As shown, the engaging member 31 includes an engaging portion 311 and a pivoting portion 312. The first end of the pivoting portion 312 is pivotally connected to the first end of the connecting member 36. The first end of the engaging portion 311 is mounted on the second end of the pivoting portion 312 and pivotally connected to the fixed seat 34. The pivoting portion 312 is pivotally arranged on the connecting member 36. The arrangement of the pivoting portion 312 enables the engaging member 31 to perform displacement and rotation simultaneously, so as to facilitate the effective and stable engagement and disengagement of the engaging member 31 with the segment matching engaging portion 11 on the vehicle frame 10. Preferably, a rotating shaft 3121 perpendicular to the pivoting portion 312 is provided at the first end of the pivoting portion 312. The pivoting portion 312 is pivotally connected to the first end of the connecting member 36 by means of the rotating shaft 3121 to facilitate the pivoting of the pivoting portion 312. Specifically, the engaging member 31 further includes a pivot shaft 313. The first end of the pivot shaft 313 is rotatably assembled to the fixed seat 34. The second end of the pivoting portion 312 is mounted on the second end of the pivot shaft 313. The first end of the engaging portion 311 is mounted on the portion between the two ends of the pivot shaft 313. The arrangement of the pivot shaft 313 provides a fulcrum for the rotation of the engaging member 31, facilitating the rotation of the engaging member 31. More specifically, the engaging portion 311 is a block-shaped member with a gradually increasing width from its first end to its second end. An insertion and carding inclined surface 314 is provided on the bottom surface of the second end of the engaging portion 311. The width of the second end of the engaging portion 311 is relatively wide and is not easily damaged, while the insertion and carding inclined surface 314 facilitates the insertion or withdrawal of the engaging portion 311 into or from the segment matching engaging portion 11. Preferably, the connecting member 36 is a rod-shaped member. The sliding direction of the sliding member 35 is the same as the sliding direction of the connecting member 36. Therefore, the structure of the connecting member 36 is simple and easy to arrange and process. The co-directional sliding of the sliding member 35 and the connecting member 36 greatly simplifies the structure of the anti-misuse height adjustment mechanism 30, making the structure of the anti-misuse height adjustment mechanism 30 more compact. Preferably, since the rotation direction of the card release operating member 33 is different from the rotation direction of the engaging member 31, the connecting member 36 will swing slightly during the sliding process.
[0046] As Figures 2 to 8As shown, a slide rail 12 is installed on the vehicle frame 10, and the fixed seat 34 is slidably assembled on the slide rail 12. All the stage matching card parts 11 are arranged on the slide rail 12 at intervals from each other. Therefore, the fixed seat 34 can slide quickly and smoothly on the vehicle frame 10 along the slide rail 12 to facilitate the rapid height adjustment of the vehicle body 20 on the vehicle frame 10. For example, the stage matching card part 11 is a slot structure, such as a counterbore structure, to facilitate the engagement between the engaging part 31 and the stage matching card part 11, but it is not limited thereto. Specifically, the upper side wall of the stage matching card part 11 is a sliding inclined surface 111 arranged obliquely inward from top to bottom. When the vehicle body 20 is adjusted upward, it can drive the engaging part 31 to move upward, so that the engaging part 311 in the engaging part 31 can be quickly pushed out by using the sliding inclined surface 111, facilitating quick release of the card. More specifically, the fixed seat 34 includes a long handle part 341 and a support seat part 342 installed at the lower end of the long handle part 341. The card release operating part 33 is arranged inside the upper end of the long handle part 341. A collar 343 is installed at the upper end of the long handle part 341. The collar 343 is slidably sleeved on the vehicle frame 10. The collar 343 can limit the dislocation of the fixed seat 34, so that the fixed seat 34 slides stably on the vehicle frame 10. The vehicle body 20 can be assembled to the vehicle frame 10 by using the support seat part 342, facilitating the disassembly and assembly between the vehicle body 20 and the vehicle frame 10. For example, the support seat part 342 has a clamping cavity to facilitate the vehicle body 20 to be clamped into the clamping cavity. The card release operating part 33 arranged at the upper end of the long handle part 341 facilitates people's operation.
[0047] Combined with the attached Figures 1 to 11, the working principle of the baby carrier 100 of the present invention will be described: When in use, the carrier body 20 is snapped onto the support portion 342 of the fixed seat 34. When the height of the carrier body 20 needs to be adjusted, by pressing the unlocking operation 33, it rotates and retracts into the fixed seat 34. The pushing protrusion 331 on the unlocking operation member 33 pushes the sliding member 35 to slide upward. The upward-sliding sliding member 35 continuously compresses the elastic member 32 upward. However, at this time, due to the weight of the fixed seat 34 and the carrier body 20 itself, the engaging portion 311 in the engaging member 31 is always engaged in the first-stage mating engaging portion 11. The insertion card inclined surface 314 of the engaging portion 311 in the engaging member 31 always abuts against the bottom surface of the first-stage mating engaging portion 11. The engaging member 31 cannot move, which can prevent the carrier body 20 from being unlocked due to accidental contact with the unlocking operation member 33. When adjusting the carrier body 20 upward, the insertion card inclined surface 314 of the engaging portion 311 in the engaging member 31 is disengaged from the abutment with the first-stage mating engaging portion 11. At this time, the elastic member 32 resumes deformation. The elastic member 32 pushes the connecting member 36 to slide upward. The connecting member 36 drives the pivot portion 312 in the engaging member 31 to pivot. The pivot shaft 313 rotates around its own axis, thereby driving the engaging portion 311 in the engaging member 31 to rotate. The engaging portion 311 in the engaging member 31 is disengaged from the engagement with the first-stage mating engaging portion 11, and the height adjustment of the carrier body 20 can be carried out. During the height adjustment of the carrier body 20, since the carrier body 20 must be lifted upward to unlock the anti-misuse height adjustment mechanism 30, accidental unlocking caused by accidental contact with the unlocking operation member 33 can be effectively avoided. The working principle is as described above.
[0048] Compared with the prior art, the anti-misuse height adjustment mechanism 30 of the present invention includes a clamping member 31, an elastic member 32, a card-releasing operation member 33, a fixed seat 34, a sliding member 35 slidably disposed within the fixed seat 34, and a connecting member 36. The fixed seat 34 is slidably disposed on the vehicle frame 10 and is adjusted by sliding relative to the vehicle frame 10. The vehicle frame 10 has at least two section mating and clamping portions 11. The clamping member 31 is movably assembled on the fixed seat 34 and selectively engages with any one of the section mating and clamping portions 11. The card-releasing operation member 33 is movably mounted on the fixed seat 34. The card-releasing operation member 33 is also linked with the clamping member 31 through the elastic member 32. And the force that the card-releasing operation member 33 drives the elastic member 32 to generate elastic deformation during the card-releasing process is less than the resistance that the fixed seat 34 and the vehicle body 20 on the fixed seat 34 together generate to block the clamping member 31 from performing the card-releasing movement. Therefore, even after the card-releasing operation member 33 is operated to release the card, since the vehicle body 20 is not adjusted upward, there is a lack of a force to lift the vehicle body 20 to balance the resistance that the fixed seat 34 and the vehicle body 20 together generate to block the clamping member 31 from performing the card-releasing movement. Therefore, the clamping member 31 always remains engaged with one of the section mating and clamping portions 11, the vehicle body 20 is locked on the vehicle frame 10, and the vehicle body 20 cannot be adjusted in height. So, during the height adjustment process of the vehicle body 20, the vehicle body 20 must be lifted upward to unlock the anti-misuse height adjustment mechanism 30. Therefore, accidental unlocking caused by accidental contact can be effectively avoided.
[0049] It can be understood that since the baby carrier 100 of the present invention includes a vehicle frame 10, a vehicle body 20, and an anti-misuse height adjustment mechanism 30, the baby carrier 100 of the present invention can avoid accidental unlocking of the vehicle body 20 on the vehicle frame 10 caused by accidental contact, effectively ensuring the use safety.
[0050] The above-disclosed are only the preferred examples of the present invention and cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention all fall within the scope covered by the present invention.
