Description

[Technical Field]

[0001] The present disclosure relates to a child car seat equipped with a misuse prevention mechanism. [Background technology]

[0002] Child seats are fixed to vehicles such as automobiles to provide a safe riding environment for children.

[0003] In some cases, child car seats are provided with a 360-degree rotational capability around a vertical axis, i.e., between a forward position (where the seat faces the direction of travel of the vehicle) and a rearward position (where the seat faces away from the vehicle). To ensure safety, children under 15 months of age are typically required to use a child car seat in the rearward position. To prevent children under 15 months of age from being accidentally placed in a child car seat in the forward position, some child car seats are provided with a misuse prevention mechanism.

[0004] In a child car seat equipped with such a misuse prevention mechanism, the user can use the operating member of the misuse prevention mechanism to switch between an unlocked mode, in which the child car seat can be switched to a forward position, and a locked mode, in which the child car seat cannot be switched to a forward position. However, conventional misuse prevention mechanisms do not have a mechanism for automatically pressing and positioning the operating member, and the operator may not operate the operating member to the specified position, resulting in the seat mode not actually being switched and the seat ultimately being used in the wrong orientation, which may have a negative impact on the child's safety when traveling.

[0005] Typically, a turntable is provided between the seat and the base for rotating the seat between a forward position and a rearward position, and in some cases, it may be desirable to separate the seat from the turntable in order to replace the seat or move the seat to another environment for use.

[0006] Therefore, it is necessary to provide a mechanism for preventing misuse of a child car seat that can automatically push and position the operating member and separate the seat from the turntable. Summary of the Invention

[0007] The present disclosure provides a child car seat including a base, a turntable, a seat, and a misuse prevention mechanism, wherein the turntable is positioned above the base and is rotatable relative to the base between a forward position and a rearward position about a substantially vertical axis; the seat is positioned above the turntable and is rotatable together with the turntable, the forward position being a position that allows the turntable to orient the seat forward, and the rearward position being a position that allows the turntable to orient the seat rearward; the misuse prevention mechanism is provided between the base, the turntable, and the seat and includes an operating member, the operating member is attached to the child car seat and is movable between a first position and a second position relative to the seat, thereby preventing or allowing relative rotation between the turntable and the base; the operating member automatically moves to the first position when it passes an intermediate position between the first position and the second position and approaches the first position, and automatically moves to the second position when it passes an intermediate position and approaches the second position.

[0008] In one embodiment, the misuse prevention mechanism further includes a positioning member that is disposed on the child seat and abuts against the operating member so as to automatically move the operating member to the first position or the second position when the operating member approaches the first position or the second position.

[0009] In one embodiment, the operating member includes a ridge that protrudes from and abuts the positioning member so that the operating member automatically moves to the first position or the second position.

[0010] In one embodiment, the operating member includes a sliding portion and two positioning recesses, the sliding portion being slidable relative to the child car seat, the two positioning recesses being disposed on the sliding portion, and the positioning member including a protrusion, when the operating member is positioned near the intermediate position, the protrusion abuts against the ridge, and the operating member automatically moves to the first position or the second position, and after the operating member passes the intermediate position and approaches the first position or the second position, the protrusion abuts against the corresponding positioning recess, pushing the operating member to the first position or the second position.

[0011] In one embodiment, the operating member further includes a toggle portion, the toggle portion being connected to the slide portion and configured to drive the slide portion to slide relative to the child seat.

[0012] In one embodiment, each of the positioning recesses extends in an arc relative to the slide portion, and the protrusion has an arcuate contour corresponding to the positioning recess.

[0013] In one embodiment, the protrusion is movable relative to the positioning member body.

[0014] In one embodiment, the ridge is formed between the two positioning recesses, and the ridge is formed in an arc shape at a position facing the protrusion.

[0015] In one embodiment, the tamper-proof mechanism further includes a linkage that swings about a lateral axis, the operating member abutting one end of the linkage and driving the linkage to swing by lateral movement of the operating member.

[0016] In one embodiment, the operating member includes an inclined surface portion, and the upper surface of the inclined surface portion extends obliquely so that one end is laterally higher than the other end. The linkage includes a handle that is held against the upper surface of the inclined surface portion and a pivot spaced apart from the handle, and the linkage is configured to swing about the pivot. When the operating member moves from the first position to the second position or from the second position to the first position, the handle abuts and slides against the upper surface of the inclined surface portion and moves vertically, driving the linkage to swing.

[0017] In one embodiment, the pivot engages beneath a cross bar attached to the seat, allowing the linkage to swing about the cross bar.

[0018] In one embodiment, the misuse prevention mechanism further includes a push member provided on the seat and restricted from moving vertically, the other end of the linkage relative to the handle is connected to an upper end of the push member, and the linkage is pivoted to drive the push member to move vertically.

[0019] In one embodiment, the linkage further includes a fork located at the other end of the linkage relative to the handle, and has two arms provided laterally on either side of the longitudinal center of the pusher member, and the pusher member is rotatably connected between the two arms via a pusher member pin.

[0020] In one embodiment, the misuse prevention mechanism further includes a drive unit that is provided on the turntable and positioned vertically below the push unit, and that restricts vertical movement of the push unit. A lower end of the push unit abuts an upper end of the drive member, and vertical movement of the push member causes the drive member to move vertically.

[0021] In one embodiment, the misuse prevention mechanism further includes a driven member, the driven member being disposed within the turntable and restricted in its vertical movement, and a lower end of the pushing member abuts an upper end of the driving member, such that vertical movement of the pushing member causes vertical movement of the driving member.

[0022] In one embodiment, the driven member has two side walls extending in a longitudinal direction and an open top, each of the side walls being symmetrically provided with a slide groove having an inclined edge relative to the longitudinal direction, and the driving member has a driving member pin extending laterally outward from each of the opposing side surfaces of the driving member, the driving member pin being inserted into a corresponding slide groove and held against a corresponding inclined edge.

[0023] In one embodiment, the child car seat further includes a protrusion, the protrusion being at least partially disposed within the turntable and movable between a locked position in which the protrusion extends from the turntable and an unlocked position in which the protrusion retracts into the turntable, the protrusion being disposed at a position near the outside of the turntable, and vertical movement of the driven member driving the protrusion to move between the locked position and the unlocked position.

[0024] In one embodiment, the misuse prevention mechanism further includes a positioning member spring, a pressing member spring, and a driving member spring, wherein the positioning member spring is provided between the positioning member and the seat and urges the positioning member upward, the pressing member spring is provided between the pressing member and the seat and urges the pressing member upward, and the driving member spring is provided between the driving member and the turntable and urges the driving member upward.

[0025] In one embodiment, the slide groove is a groove having a substantially right-angled triangle shape, and the hypotenuse of the right-angled triangle is located on a vertical side of the slide groove and functions as the inclined edge. The misuse prevention mechanism further includes a driven member spring, the driven member spring being disposed between the driven member and the turntable and biasing the driven member so as to tend to move toward the outside of the turntable, thereby tending to drive the driven member to extend the protrusion from the turntable.

[0026] In one embodiment, the turntable includes a disk portion located below the turntable, the base includes an opening and a block portion, the opening is located above the base and is circular, the disk portion is rotatably engaged with the opening, and the block portion is located on the edge of the opening, and when the protrusion is in the locked position, the protrusion interferes with the block portion to limit the rotation range of the turntable relative to the base.

[0027] In one embodiment, the sheet is selectively separated from the turntable. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0029] Although the present disclosure is illustrated and described herein with reference to particular embodiments, the present disclosure should not be limited to the details shown. Rather, various changes can be made to those details within the scope and range of equivalents of the claims without departing from the present disclosure.

[0030] Furthermore, the descriptions of directions such as "front," "rear," "upper," and "lower" in the present disclosure are for the convenience of understanding, and the present disclosure is not limited to these directions and can be adjusted according to actual circumstances. Although the present disclosure has been described with reference to exemplary embodiments, the terms used are exemplary and illustrative, and not limiting.

[0031] 1 and 2, a child car seat 1 according to the present disclosure is shown in its entirety. The child car seat 1 includes a base 300, a turntable 200, a seat 400, and a misuse prevention mechanism 100.

[0032] The base 300 is located under the child car seat 1 in order to secure the child car seat 1 to a vehicle such as an automobile.

[0033] The turntable 200 is positioned above the base 300 and is rotatable relative to the base 300 between a forward position and a rearward position about a substantially vertical axis.

[0034] The seat 400 is positioned above the turntable 200 and can rotate together with the turntable 200. That is, the turntable 200 can switch the seat 400 between a forward position and a rearward position. Here, the forward position shown in FIG. 2 is a position where the turntable 200 allows the seat 400 to face forward (i.e., in the direction of travel of the vehicle), and the rearward position shown in FIG. 1 is a position where the turntable 200 allows the seat 400 to face rearward.

[0035] The misuse prevention mechanism 100 is disposed between the base 300, the turntable 200, and the seat 400. The misuse prevention mechanism 100 can prevent or allow relative rotation between the turntable 200 and the base 300.

[0036] In some applications, the seat 400 is configured to be removably coupled to the turntable 200. The misuse prevention mechanism 100 of the present disclosure is configured to allow separation and engagement between the seat 400 and the turntable 200.

[0037] 3 and 4, a seat 400 of the child car seat 1 is shown.

[0038] At least a portion of the misuse prevention mechanism 100 is installed within the seat 400, specifically within the front side of the lower end of the seat 400. The misuse prevention mechanism 100 includes an operating member 110 for receiving operations by the user. The operating member 110 is attached to the seat 400 and can be operated from outside the seat 400.

[0039] More specifically, the operating member 110 can be moved relative to the seat 400 between a first position shown in FIG. 3 and a second position shown in FIG. 4 to switch the misuse prevention mechanism 100 between a locked position and an unlocked position.

[0040] For example, in the first position shown in FIG. 3, the operating member 110 is on the right side in the horizontal direction shown in FIG. 3, and therefore the misuse prevention mechanism 100 is in the locked position. At this time, the rotation range of the turntable 200 (and the seat 400) relative to the base 300 is limited, and the turntable 200 cannot be rotated to the forward position. The principle behind the rotation range limitation will be described in detail later. When the operating member 110 is in the first position, a mark on the operating member 110 is exposed on the outside of the seat 400 to notify the user of the current status of the misuse prevention mechanism 100. This mark may be, for example, "<15M," indicating that the current status is suitable for children under 15 months old.

[0041] In the second position shown in FIG. 4, the operating member 110 is on the left side in the horizontal direction as shown in FIG. 4, and therefore the misuse prevention mechanism 100 is in the unlocked position. At this time, the rotation range of the turntable 200 (and seat 400) relative to the base 300 is not restricted, and the turntable 200 is allowed to rotate to the forward position or the rearward position. When the operating member 110 is in the second position, another mark on the operating member 110 is exposed on the outside of the seat 400 to inform the user of the current status of the misuse prevention mechanism 100. This mark may be, for example, ">15M," indicating that the current status is suitable for children aged 15 months and older.

[0042] The principle by which the misuse prevention mechanism 100 limits the range of rotation of the turntable 200 relative to the base 300 will be described with reference to FIGS.

[0043] As shown in FIG. 5, the turntable 200 may be disposed on a base 300 and configured to rotate about a substantially vertical axis. As shown in FIG. 6, the turntable 200 includes a disk portion 210 located below the turntable 200. At least a portion of the misuse prevention mechanism 100 may be disposed on the turntable 200, and the protrusion 170 of the misuse prevention mechanism 100 may extend from the edge of the disk portion 210. As shown in FIG. 7, the base 300 includes an opening 310 and a block portion 320. The opening 310 is located above the base 300 and has a circular shape. The block portion 320 is located on the edge of the opening 310. It should be understood that the disk portion 210 is rotatably engaged with the opening 310. When the protrusion 170 is in the locked position, the protrusion 170 and the block portion 320 interfere with each other to limit the rotation range of the turntable 200 relative to the base 300. For example, the block portion 320 is disposed along the semicircle of the opening 310. When the protrusion 170 is in the locked position (i.e., extending from the turntable 200), the protrusion 170 can only move within the rear half circle of the opening 310, thereby restricting the turntable 200 from rotating to a forward position.

[0044] The relationship between the components of the misuse prevention mechanism 100 will be described with reference to FIGS.

[0045] The misuse prevention mechanism 100 includes an operating member 110, a toggle portion 111, a slide portion 112, a positioning member 120, a positioning member spring 129, a linkage 130, a pushing member 140, a pushing member pin 148, a pushing member spring 149, a driving member 150, a driving member pin 158, a driving member spring 159, a driven member 160, a driven member spring 169, and a protrusion 170.

[0046] The operating member 110 is disposed on the seat 400 and moves laterally relative to the seat 400 between a first position and a second position (a position perpendicular to the plane of the paper on which FIGS. 8 to 11 are drawn) in response to an operation by a user. According to the design of the present disclosure, when the operating member 110 passes an intermediate position between the first and second positions and approaches the first position, the operating member 110 automatically moves to the first position, and when the operating member 110 passes the intermediate position and approaches the second position, the operating member 110 automatically moves to the second position, which will be described in detail later.

[0047] The positioning member 120 is disposed on the seat 400 and abuts against the operating member 110, and when the operating member 110 approaches the first position or the second position, automatically moves the operating member 110 to the first position or the second position, as will be described in detail later.

[0048] The positioning member spring 129 is disposed between the positioning member 120 and the seat 400 and biases the protrusion 121 of the positioning member 120 upward.

[0049] Linkage 130 extends longitudinally toward the inside of seat 400 and pivots about a lateral axis (i.e., about crossbar 410). Operating member 110 abuts one end of linkage 130 (i.e., the end where handle 131 is located, see Figures 9 and 11), and lateral movement of operating member 110 causes linkage 130 to pivot. It should be understood that linkage 130 may extend in a different direction, for example, in an oblique direction.

[0050] The push member 140 is provided vertically on the seat 400 and is restricted to be movable in the vertical direction. The other end of the linkage 130 relative to the handle 131 is engaged with the upper end of the push member 140, and the push member 140 is driven to move in the vertical direction by swinging the linkage 130. It should be understood that the push member 140 may be disposed in other directions and / or moved in other directions, for example, may be disposed diagonally and / or moved diagonally.

[0051] A pusher pin 148 is inserted between the pusher member 140 and the linkage 130 to allow for interaction between the pusher member 140 and the linkage 130, as will be described in more detail below.

[0052] The push member spring 149 is disposed between the push member 140 and the seat 400 and biases the push member 140 upward.

[0053] The driving member 150 is provided inside the turntable 200, is arranged vertically below the pushing member 140, and is arranged to be movable in the vertical direction. The lower end of the pushing member 140 abuts against the upper end of the driving member 150, and vertical movement of the pushing member 140 causes the driving member 150 to move vertically.

[0054] A drive member spring 159 is disposed between the drive member 150 and the turntable 200 and biases the drive member 150 upward.

[0055] It can be seen that the driving member 150 and the pushing member 140 are disposed on the turntable 200 and the seat 400, respectively. When the turntable 200 and the seat 400 move away from each other, the driving member 150 and the pushing member 140 also move away from each other accordingly. When the seat 400 is engaged with the turntable 200, the pushing member 140 extends from the bottom of the seat 400 and enters the turntable 200 from the top of the turntable 200, pushing the driving member 150 downward.

[0056] The driven member 160 is disposed in the vertical direction of the turntable 200 and is restricted to be movable in the vertical direction. The driven member 160 is coupled to the driving member 150, and vertical movement of the driving member 150 drives the driven member 160 to move in the vertical direction.

[0057] The driven member spring 169 is disposed between the driven member 160 and the turntable 200 and biases the driven member 160 so that the driven member 160 tends to approach the outside of the turntable 200, i.e., so that the driven member 160 tends to drive the protrusion 170 to protrude from the seat 400.

[0058] The protrusion 170 is at least partially disposed within the turntable 200 and is movable between a locked position in which the protrusion extends from the turntable 200 and an unlocked position in which the protrusion retracts into the turntable 200. The protrusion 170 is disposed at a position on the driven member 160 near the outside of the turntable 200, and longitudinal movement of the driven member 160 drives the protrusion 170 to move between the locked and unlocked positions.

[0059] 8 and 9, the misuse prevention mechanism 100 is in the unlocked position. At this time, the operating member 110 is in the first position, and the end of the linkage 130 that abuts the operating member 110 is raised upward. The end of the linkage 130 opposite the operating member 110 is pressed downward, driving the pushing member 140 to move downward. The pushing member 140 presses the driving member 150, and the driving member 150 drives the driven member 160 to move toward the inside of the turntable 200. Therefore, the protrusion 170 provided on the driving member 150 is housed inside the turntable 200.

[0060] 10 and 11 , when the user moves the operating member 110 to the second position, the operating member 110 no longer presses the end of the linkage 130 that abuts the operating member 110 upward, and the end of the linkage 130 that faces the operating member 110 no longer presses the push member 140 downward. Therefore, the push member 140 is reset upward by the action of the push member spring 149, driving the linkage 130 to rotate clockwise and resetting it. Because the push member 140 no longer presses the drive member 150 downward, the drive member 150 is reset upward under the action of the drive member spring 159, and the driven member 160 is no longer driven to move toward the turntable 200. The driven member 160 is reset toward the outside of the turntable 200 under the action of the driven member spring 169, driving the protrusion 170 to extend from the turntable 200, and the tamper-proof mechanism 100 is in the locked position.

[0061] The structures of the operating member 110, the positioning member 120, and the pushing member 140 will be described with reference to FIGS.

[0062] As shown in FIGS. 13 and 14, the operating member 110 includes a slide portion 112, a toggle portion 111, two positioning recesses 113, an inclined surface portion 114, and a ridge 115.

[0063] The slide portion 112 extends laterally and can slide relative to the outer surface of the seat 400 (i.e., relative to the child car seat 1). The toggle portion 111 is connected to the outer side of the slide portion 112, which is exposed on the outside of the seat 400, and can drive the slide portion 112 to move laterally relative to the seat 400. A mark may be provided on the outer surface of the slide portion 112, and the mark may be provided on each side of the toggle portion 111 so that the user can easily understand the state of the tamper-proof mechanism 100 (see FIGS. 3 and 4). It should be understood that the slide portion 112 can also be arranged to extend in other directions, such as vertically, diagonally, or curvedly. The slide portion 112 may be attached to the outer surface of the seat 400, embedded in the seat 400, or hung outside the seat 400. The toggle portion 111 may be exposed on the outside of the seat 400 or hidden within the seat 400.

[0064] The two positioning recesses 113 are located inside the slide portion 112, are located at the horizontal center of the slide portion 112, and are symmetrical with respect to the vertical center of the slide portion 112. It should be understood that the two positioning recesses 113 may be asymmetrically located on one side of the slide portion 112 or on both horizontal sides of the slide portion 112. Each of the positioning recesses 113 extends cambered relative to the slide portion 112 from a horizontal midpoint. A ridge 115 is formed between the two positioning recesses 113, and the ridge 115 protrudes downward relative to the positioning recess 113. That is, the bottom surface of the operating member 110 forms a shape in which both sides of the horizontal positioning recesses 113 and the ridge 115 are higher than the center. The ridge 115 protrudes toward the positioning member 120 and abuts against the protrusion 121 of the positioning member 120, so that the operating member 110 automatically moves to the first position or the second position. The ridge 115 is curved at the position facing the protrusion 121 to prevent the ridge 115 from locking with the protrusion 121 .

[0065] The inclined surface portion 114 is formed on the inside of the positioning recess 113 in the vertical direction, and the upper surface of the inclined surface portion 114 extends obliquely so that one end is higher than the other end in the horizontal direction. It should be understood that the inclined surface portion 114 may be formed in a different position, for example, vertically above or below the positioning recess 113, or on one lateral side surface of the positioning recess 113, or between the positioning recess 113 and the slide portion 112, as long as it can abut against the handle 131 of the linkage 130.

[0066] As shown in FIG. 15 , the positioning member 120 is positioned vertically below the operating member 110. In other embodiments, the positioning member 120 can be positioned in other directions relative to the operating member 110 as long as the positioning recess 113 and the ridge 115 can abut against the protrusion 121. The positioning member 120 includes a positioning member body 122 and a protrusion 121. The positioning member body 122 is generally rectangular and is disposed within the seat 400. The protrusion 121 is vertically movable within the positioning member body 122 and has an arc-shaped protrusion 121 that fits into the positioning recess 113. A positioning member spring 129 biases the protrusion 121 upward. When the operating member 110 approaches the intermediate position, the protrusion 121 abuts against the ridge 115, and the operating member 110 automatically moves to the first position or the second position. When the operating member 110 passes the intermediate position close to the first position or the second position, the protrusion 121 abuts against the corresponding positioning recess 113, pushing the operating member 110 to the first position or the second position.

[0067] More specifically, the intermediate position refers to the position where the ridge 115 of the operating member 110 corresponds exactly to the upper end of the arc-shaped protrusion 121 .

[0068] As shown in FIG. 13, the linkage 130 includes a handle 131 , a pivot 132 , and a fork 133 .

[0069] The handle 131 is located at one longitudinal end of the linkage 130 and is held against the upper surface of the inclined surface portion 114. It should be understood that the handle 131 may be formed at another position on the linkage 130, for example, at the vertical upper end, the vertical lower end, or on one lateral side of the linkage 130, as long as it abuts the slide portion 112.

[0070] Pivot 132 is spaced apart from handle 131, and linkage 130 can swing about pivot 132. More specifically, pivot 132 is an arc-shaped groove that opens upward and extends laterally, and is engaged under a crossbar 410 installed in seat 400, thereby allowing linkage 130 to swing about crossbar 410. It should be understood that pivot 131 may be located near the longitudinal middle of linkage 130 or near any end of linkage 130, and that pivot 132 may have other shapes as long as it can swingably engage with crossbar 410.
