Background Technology

[0002] Highchairs provide a convenient and safe place for babies and children to eat and pass the time. Most highchairs are designed for babies around six months old, when they can sit up without assistance to eat solid foods. Newborns to six-month-old babies cannot sit upright and are best kept lying down or in a semi-sitting position at a slight incline, as their backs are not yet developed enough to support their full weight and may become strained from overexertion. Highchairs and cradles are essential for a baby's care and comfort. Highchairs are typically used during feedings, while cradles provide a comfortable resting place for the baby. There is a desire for a multi-functional baby cradle that can be mounted on a highchair, allowing parents to use the highchair for feeding and the cradle for rest without requiring multiple pieces of equipment, thus accommodating children from newborns to several years old and / or larger children.

In one embodiment, seat member 1210 is intended for use by toddlers or infants capable of supporting themselves in an upright position, such as children typically six months or older. Therefore, seat member 1210 is adapted to receive a child sitting in contact with seat member 1210, with the child's back at least partially supported by the seat back.

[0121] Continue to refer to Figures 1 to 3The seat component 1210 is supported by a plurality of legs 1214a-1214d spaced apart from each other. In the non-limiting embodiment shown, the legs are generally arranged near each corner of the seat component 1210. Thus, as shown, the high chair includes a first right front leg 1214a, a second left front leg 1214b, a third right rear leg 1214c, and a fourth left rear leg 1214d. In one embodiment, each of the plurality of legs may be substantially identical. However, in other embodiments, the configuration of the legs may vary. For example, the rear legs 1214c, 1214d may have a first configuration, and the front legs 1214a, 1214b may have a second configuration different from the first configuration. For example, although the overall cross-sectional shape and size of the front and rear legs 1214a, 1214b, 1214c, 1214d appear to be the same, the axial length of the rear legs 1214c, 1214d is greater than the axial length of the front legs 1214a, 1214b.

[0122] The distal end 1215 of each of the front legs 1214a, 1214b and the rear legs 1214c, 1214d is configured to contact a support surface, such as a floor, to support the bar chair in an upright configuration. As shown, the proximal opposite ends 1216 of each leg 1214a, 1214b, 1214c, 1214d are secured to a corresponding portion of the seat member 1210.

[0123] Furthermore, the cradle body 1100 includes a mounting member 1110 that allows it to be attached to a high chair frame, as described in more detail below. The mounting member 1110 is designed to be adaptable, for example, enabling the cradle to be easily converted between a high chair and a cradle stand or a rocking chair. The mounting member 1110 ensures a secure attachment, preventing any accidental movement or disassembly.

[0124] Figure 4 This is an isometric view showing an exemplary or representative embodiment of the mounting component 1110 of the cradle. Figure 5A and 5B The sequence of engagement steps of an exemplary or representative embodiment of the cradle on a high chair is shown in planar cross-sectional views, in the unlocked state or configuration and during the locking process. Figure 6 This is an enlarged plan view illustrating an exemplary or representative embodiment of the locking mechanism.

[0125] Reference Figure 4-6 An exemplary or representative cradle can be connected to the seat member 1210 via at least one mounting member 1110. For example... Figure 4As best illustrated, in one embodiment, a first mounting member is disposed at a first end of a buffer (shock absorber) member, and a second mounting member is disposed at a second end of the buffer member. In some cases, the mounting member 1110 is permanently fixed to or integrally formed with the cradle. For example, the mounting member 1110 may be an injection-molded part molded into the cradle.

[0126] Figure 5A An example of a mounting member 1110 installed within a corresponding opening is shown. At least one mounting member 1110 may be received within a corresponding opening or cavity formed in a portion of the seat member 1210. For example, a first mounting member may be slidably and / or rotatably received within a first opening 1211a formed on the front surface of a first upright sidewall 1211, and a second mounting member may be slidably and / or rotatably received within a second opening 1212a formed on the front surface of a second upright sidewall 1212 (see [reference]). Figure 16 ).

[0127] Reference Figure 6 Additional details of the mounting member 1110 with a locking mechanism are shown. As shown, each mounting member 1110 may include a body 1111 having a first end 1111a connectable to a cradle and a second end 1111b connectable to a seat member 1210. A gap 1112 extends over a portion of the length of the body 1111, such that the body 1111 includes a primary finger 1113 and a secondary finger 1114 at its second end 1111b. The primary finger 1113 and the secondary finger 1114 are connected to each other at the first end 1111a of the body 1111, but are separated from each other over the length of the gap 1112. The gap 1112 may have a non-linear configuration, or alternatively, may have a linear configuration. In the non-limiting embodiment shown, the gap 1112 includes a first straight portion and a second arcuate or curved portion arranged at the second end 1111b of the body 1111. However, gaps 1112 with any suitable configuration are contemplated herein. Therefore, the resulting primary finger 1113 and secondary finger 1114 can have any suitable configuration. In one embodiment, the secondary finger 1114 is flexible or bendable relative to the primary finger 1113, for example, during the installation or separation of the mounting member 1110 from the seat member 1210.

[0128] To connect the cradle to the seat member 1210, at least one mounting member 1110 is inserted into at least one opening 1210a, 1220b formed around the seat member 1210. When the mounting member 1110 is slidably inserted into the openings 1210a, 1220b, the secondary finger 1114 is configured to bend toward the primary finger 1113. When the mounting member 1110 reaches the fully inserted position, as... Figure 5BAs shown, a portion of the secondary finger 1114 may be disposed outside the seat member 1210. Outside the seat member 1210, the secondary finger 1114 is no longer limited by the total height of the openings 1210a, 1220b, and can therefore be biased to its original position. In one embodiment, the secondary finger 1114 includes a notch 1115 configured to engage with a surface of the seat member 1210 to limit lateral movement of the cradle away from the seat member 1210. To separate the cradle from the seat member 1210, an upward force, as indicated by F1, is applied to the exposed portion of the secondary finger 1114. This force bends the secondary finger 1114 toward the primary finger 1113, aligning the primary finger 1113 and the secondary finger 1114 of the mounting member 1110 with the openings 1210a, 1220b for removal therefrom. The mounting member 1110 may comprise a flexible material, such as an engineering resin or a thermoplastic material.

[0129] In the non-limiting embodiment shown, the main finger 1113 extends axially beyond the secondary finger 1114. Therefore, when the mounting member 1110 is installed within the openings 1210a, 1220b, the second end of the main finger 1113 is configured to engage and rest on the shelf 1213 formed in the openings 1210a, 1220b. This engagement between the main finger 1113 and the shelf 1213 is configured to resist rotation of the cradle and relieve stress on the secondary finger 1114. For example, see reference... Figure 2 and 5B The orientation of the cradle allows the upward force applied to it to be transmitted to the junction of the main finger 1113 and the shelf 1213, rather than to the secondary finger 1114.

[0130] As shown in the figure, the interior of the cradle body 1100 has, for example but not limited to, soft materials or cushioning padding (inserts) to provide comfort.

Figure 14 It is an isometric rear view of an exemplary or representative embodiment of a cradle including a suspension attachment 1120 in a first configuration on a high chair.

[0132] Reference Figure 7A-14 An exemplary or representative modular cradle seat system 10 includes a cradle body 1100 mounted to a high chair frame in a first configuration and a cradle body 1100 mounted to a cradle frame in a second configuration. In the illustrated non-limiting embodiment, the cradle body 1100 can be easily mounted to a cradle frame (e.g., a rocking chair, rocker arm, or other suitable connector) by aligning mounting members 1110 and engaging a locking mechanism, thereby providing an alternative independent mode of operation for the cradle of the disclosed system. Figure 7A As shown, the cradle body 1100 is mounted on the high chair via mounting member 1110 and locking mechanism. Similarly, as Figure 7B As shown, the cradle body 1100 can be attached to the cradle frame. The cradle can be mounted on the cradle frame in a manner similar to that described above, except that the curved bottom replaces the high chair legs, as described in more detail below.

[0133] In some cases, the cradle frame includes at least one curved base (or rocker arm, curved plate, or other suitable support) for receiving the cradle body 1100 on a supporting surface (e.g., a floor). The curved base may be configured to have a continuous curvature, such as an arch curving upwards from the bottom. To prevent undesirable slippage during use, the underside of the curved base may have an anti-slip strip, such as a rubber band or anti-slip layer, typically extending the length of the curved base. Furthermore, those skilled in the art will recognize that the size, shape, and material selection of the anti-slip strip should be sufficiently robust for its intended use and application, and are typically determined, for example, but not limited to, based on its application and the expected stress or weight load, as well as aesthetic considerations.

[0134] In a representative embodiment of the cradle frame in the second configuration shown, a support member configured to support the cradle body 1100 is disposed on the upper surface of a curved base. Similarly, an opening or cavity is formed in a portion of the support member, which is configured to receive a corresponding mounting member 1110 of the cradle body 1100. For example, a first mounting member of the cradle body 1100 may be slidably and / or rotatably received in a first opening formed in the upper portion of the first support member of the cradle frame, and a second mounting member of the cradle body 1100 may be slidably and / or rotatably received in a second opening formed in the lower portion of the second support member of the cradle frame.

[0135] In the representative embodiment shown, the support member also includes an arcuate or curved portion disposed on the upper part of the support member. Furthermore, although shown as having substantially rounded edges, those skilled in the art will recognize that numerous other designs are available, and are substantially equivalent, for example, but not limited to those shown in the various figures.

[0136] In a representative embodiment of the cradle frame shown, the support member may be provided with a release member configured to unlock the mounting member 1110. In exemplary or representative embodiments, the release member may have any of a variety of shapes or sizes that are symmetrical or asymmetrical, such as, but not limited to, button-shaped, pear-shaped, triangular, rectangular, spherical, tab-shaped, bulb-shaped, or bulbous, or as shown, semi-elliptical or ovate, i.e., any shape that a caregiver can operate and / or slide with their thumb or finger.

[0137] Reference Figure 8A-14 Additional embodiments of the cradle body 1100 on a high chair in a first configuration and on a cradle frame in a second configuration are shown. In the first configuration, the cradle body 1100 is attached to the high chair; while in the second configuration, the cradle body 1100 is attached to the cradle frame. For example, Figure 9B An additional embodiment of the cradle body 1100 on the cradle frame in a second configuration is shown, in which the combination of the cradle frame and the cradle body can also be referred to as a rocking chair.

[0138] Reference Figure 13A and 13BAnother representative embodiment of a cradle body 1100 on a high chair is shown. The cradle body 1100 has a support member projecting downward from a base of the cradle body 1100, wherein the base has a recess for receiving, for example but not limited to, an infant. As shown, a mounting member 1110 of the cradle body 1100 extends from the rear side of the support member of the base, and the mounting member 1110 can be received within a corresponding opening or cavity formed in a portion of the seat member 1210 of the high chair. Furthermore, although shown as having substantially elongated edges, those skilled in the art will recognize that numerous other designs are also available and substantially equivalent, for example but not limited to those shown in the various figures.

[0139] like Figure 12 and 14 As shown in the illustrated representative embodiment of the cradle body 1100 on the high chair, when the cradle body 1100 is in the first configuration, the cradle may be equipped with a suspension attachment 1120 for holding accessories such as toy sticks, mobile devices (mobile phones), projectors, audio units, light-emitting sticks, or other suitable units.

[0140] Figure 15 This is an isometric view showing an exemplary or representative embodiment of a high chair including a crotch member 1220. Figure 16 This is an isometric view showing an exemplary or representative embodiment of a high chair and crotch member 1220 in a disassembled state. Figures 17 to 19 The diagram shows, in planar cross-sectional views, the sequence of engagement steps of an exemplary or representative embodiment of the crotch member 1220 on the high chair in the unlocked state or in the locked state and during the locking process.

[0141] In the non-limiting embodiment shown, the crotch member 1220 of the armbar is not itself configured to be coupled to the seat member 1210. Instead, the crotch member 1220 is positioned as desired due to the connection between the buffer member and the seat member 1210 via one or more mounting members 1110. However, embodiments in which a portion of the crotch member 1220 may also be coupled to the seat member 1210 are also within the scope of this disclosure.

[0142] Figure 20 This is an isometric view showing an exemplary or representative seat member 1210 and legs in a disassembled state, according to an exemplary or representative embodiment of a high chair. Figure 21 This is a diagram showing an exemplary or representative seat member 1210 and legs in an assembled state, illustrating an exemplary or representative embodiment of a high chair.

[0143] As shown in the figure, at least one of legs 1214a, 1214b, 1214c, and 1214d is detachably connectable to a corresponding portion of seat member 1210. In the non-limiting embodiment shown, at least one of the legs, such as rear legs 1214c and 1214d, is connected via a quick-connect coupling mechanism (…). Figure 20 and 21 It can be connected to the seat component 1210 without the need for any additional or external tools, such as screwdrivers.

[0144] Figure 22 This is an isometric view illustrating an exemplary or representative embodiment of a high chair with an arm, including a tray 1230. As shown, the tray 1230 can be mounted to a portion of the high chair. The tray 1230 may have a generally flat upper surface configured to support items, such as food, at a location easily accessible to the occupant of the seat member 1210. In the non-limiting embodiment shown, the tray 1230 may be positioned to overlap with the upper surface of the arm. Although a portion of the tray 1230 may contact or abut against an adjacent surface of the seat member 1210, such as the front of an upright sidewall, the tray 1230 is not constructed to be coupled to or supported by any part of the seat member 1210. As used herein, the term "coupled" is intended to mean a mechanical connection or fastening that restricts relative movement of two or more components in at least one direction. Rather, in one embodiment, the tray 1230 is configured only to be directly coupled to or attached to the arm. Thus, in one embodiment, the tray 1230 cannot be attached to the high chair when the arm is not connected to it.

[0145] refer to Figure 23 The illustration shows a perspective view of a child seat (also known as a rocking chair) 20 according to an embodiment of the present disclosure, wherein the child seat 20 is in the installed position.

[0146] Specifically, Figure 23 A child seat 20 is shown as viewed from a frontal oblique side. The child seat 20 may include a seat assembly 2100 and a base assembly 2200 for supporting the seat assembly 2100. When the child seat 20 is locked, the seat assembly 2100 is fixedly connected to the base assembly 2200; when the child seat 20 is unlocked, the seat assembly 2100 can be detached from the base assembly 2200.

[0147] A seat and / or seat cover can be supported and mounted on the seat assembly 2100 so that a child can be placed on the seat and / or seat cover. Figure 23 The image shows a child seat 20 that can rock back and forth for children to rock and play with. The child seat 20 has a generally symmetrical structure.

[0148] Seat assembly 2100 may include seat frame 2110 and connector 2120, wherein seat frame 2110 is used to support and mount seat and / or seat fabric. Connector 2120 is disposed under seat frame 2110 and can be mounted to base assembly 2200.

[0149] In one embodiment, the seat frame 2110 may have an approximately rectangular frame configuration. However, this disclosure is not limited to this; other shapes, such as elliptical or circular, are also feasible. The seat frame 2110 may be a single piece or may be assembled from multiple parts. Typically, the seat frame 2110 may be a tubular component made of hollow tubes. Figure 23 The illustrated seat frame 2110 is made of a hollow tube with an approximately rectangular cross-section, and the hollow tube has a flat top surface and a flat bottom surface. The flat top surface can be used to support and mount the seat and / or seat fabric, and the insert 2120 can be mounted to the flat bottom surface. The seat frame 2110 designed in this way is not only strong and reliable, but also easy to manufacture.

[0150] In one embodiment, the seat frame 2110 may be detachably mounted to the connector 2120. Alternatively, the seat frame 2110 may be integrally formed with the connector 2120. For this purpose, the connector 2120 may extend from the seat frame 2110 (e.g., from the bottom surface of the seat frame 2110) toward the base assembly 2200, in other words, along... Figure 23 The first direction shown extends downwards.

[0151] In this text, "first direction" can be understood as a direction that forms a non-zero angle with the vertical direction, allowing the seat frame 2110 to be tilted relative to the support surface used to house the child seat 20. Here, "vertical direction" means a direction perpendicular to the support surface (e.g., the ground) used to house the child seat 20. In this way, the child can recline in the child seat 20 with their head higher than their hips.

[0152] The width of the upper surface of the connector 2120 can optionally match the width of the lower surface of the seat frame 2110. The connector 2120 can be fixed to both sides of the seat frame 2110, located slightly below the middle of the longitudinal direction of the seat frame 2110, so that the child seat 20 is in a forward-lower-rear-high posture when stationary. For example, the midpoint of the connection between the connector 2120 and the seat frame 2110 can be located in the forward 1 / 3 to 1 / 2 range of the longitudinal length of the seat frame 2110, so that the seat assembly 2100 can be installed above the base assembly 2200 and at a certain distance from the support surface, so that the seat assembly 2100 will not collide with the support surface when the child seat 20 rocks back and forth.

[0153] The base assembly 2200 may include a connecting seat 2210, a rocker arm 2220, and a support rod 2230.

[0154] Two rocker arms 2220 can be provided, one on each side of the child seat 20 (left and right). Each rocker arm 2220 can be positioned approximately longitudinally (i.e., Figure 24 The curved rods (shown in the front-to-back direction) extend to allow the base frame assembly 2200 to rock back and forth on the support surface without easily tipping over. The two rocker arms 2220 can be mounted parallel to each other on the support surface; or alternatively, the two rocker arms 2220 can be arranged such that the distance between the two front ends is less than the distance between the two rear ends.

[0155] Each rocker arm 2220 may be provided with a connecting seat 2210. For example, the connecting seat 2210 may be provided on the top surface of the rocker arm 2220, and the width of the bottom surface of the connecting seat 2210 may optionally match the width of the top surface of the rocker arm 2220. The connecting seat 2210 may extend from the top surface of the rocker arm 2220 toward the seat assembly 2100, in other words, extend upward along a first direction. The connecting seat 2210 may be fixed approximately at a position substantially at the midpoint of the longitudinal direction of the rocker arm 2220. For example, the midpoint of the connection position between the connecting seat 2210 and the rocker arm 2220 may be located in the range of the forward 1 / 3 to 1 / 2 of the length of the rocker arm 2220.

[0156] Support rods 2230 can be disposed between two rocker arms 2220 located on both sides of the child seat 20 to increase the overall rigidity of the base assembly 2200. Support rods 2230 can be one, two, or more, selected according to the specific configuration and load-bearing capacity of the base assembly 2200 to ensure its robustness and safety. In one embodiment, two support rods 2230 may optionally be disposed laterally between two longitudinally extending rocker arms 2220 in a parallel manner. Alternatively, the two support rods 2230 may be disposed non-parallel, for example, in a cross configuration, between the two rocker arms 2220. The two ends of the support rods 2230 are respectively connected to the facing inner surfaces of the two rocker arms 2220, thereby forming the base assembly 2200 into a rigid whole, ensuring the structural stability of the child seat 20 during rocking.

[0157] In one embodiment, the connecting seat 2210 may have a release operation member 2240 provided on its laterally outward surface. For ease of operation, the release operation member 2240 may be located approximately at the upper part of the connecting seat 2210 in the vertical direction. When the child seat 20 is in the locked state, the outer surface of the release operation member 2240 is approximately flush with the outer surface of the connecting seat 2210, making the overall appearance of the child seat 20 more aesthetically pleasing and preventing improper operation due to accidental contact by the user. In other embodiments, the release operation member 2240 may be located in other positions.

[0158] The seat assembly 2100 and the base frame assembly 2200 are detachably connected via a snap-fit ​​mechanism between the connector 2120 and the connecting seat 2210. The lower surface shape of the connector 2120 matches the upper surface shape of the connecting seat 2210. Furthermore, the circumferential surface shape of the connector 2120 matches the circumferential surface shape of the connecting seat 2210. When the connector 2120 is inserted into the connecting seat 2210 to install the seat assembly 2100 and the base frame assembly 2200, the circumferential wall of the connector 2120 is flush with the circumferential wall of the connecting seat 2210, resulting in a more aesthetically pleasing product.

[0159] When the child seat 20 is stationary, the lateral projection length of the seat frame 2110 on the horizontal plane can be equal to or slightly less than the lateral projection length of the two rockers 2220 as a whole on the horizontal plane, which is beneficial to the overall stability of the child seat 20.

[0160] refer to Figure 24 The diagram shows a perspective view of a child seat 20 in a disassembled state according to an embodiment of the present disclosure. The seat frame 2110 may be composed of a first frame 2111 and a second frame 2112 connected together. Optionally, the first frame 2111 and the second frame 2112 are abutted and fixed to each other to form a closed-loop seat frame 2110. The first frame 2111 and the second frame 2112 may be substantially symmetrical from left to right and abutted to each other. Optionally, the first frame 2111 and the second frame 2112 may each be U-shaped, with the two free ends of the U-shape abutting to each other.

[0161] The two free ends of the first frame 2111 and the two free ends of the second frame 2112 can be connected by a plug-in connection. Specifically, one of the free ends of the first frame 2111 and the corresponding free ends of the second frame 2112 is configured as a large end interface 2113 that conforms to the outer peripheral contour of the seat frame 2110, and the other can be configured, for example, by a tube shrinking process, as a small end interface 2114 that conforms to the inner peripheral contour of the large end interface 2113. The small end interface 2114 can be inserted into and fixed in the large end interface 2113, thereby achieving a tight assembly of the first frame 2111 and the second frame 2112. Figure 24The big-endian interface 2113 and little-endian interface 2114 shown are merely an example on the first frame 2111 and the second frame 2112. The big-endian interface 2113 and little-endian interface 2114 can be interchanged as needed.

[0162] In one embodiment, the small-end interface 2114 may be provided with an elastic element and a protrusion (not shown). For example, the elastic element may be a spring sheet fixed in the small-end interface 2114, and the protrusion may be a protrusion (not shown) provided on the movable end of the spring sheet. Through holes are respectively provided at positions corresponding to the protrusions in the small-end interface 2114 and the large-end interface 2113, so that the protrusion can elastically move between them when the through holes of the small-end interface 2114 and the large-end interface 2113 are aligned with each other.

[0163] Specifically, when the small end interface 2114 is inserted into the large end interface 2113, the protrusion extending from the through hole of the small end interface 2114 is constrained by the inner wall of the large end interface 2113 and overcomes the elastic force of the elastic element to retract inward until the small end interface 2114 is successfully inserted into the predetermined position in the large end interface 2113 (that is, the through holes of the small end interface 2114 and the large end interface 2113 are basically aligned). At this time, under the action of the elastic force of the elastic element, the protrusion passes through the through hole on the small end interface 2114 and extends into the corresponding through hole of the large end interface 2113 sleeved outside the small end interface 2114. In this way, the small end interface 2114 and the large end interface 2113 can be locked together, thereby locking the second frame 2112 and the first frame 2111 together. If disassembly is required, pressure can be applied from the outside to the protrusion inside the through hole of the large-end interface 2113, causing the protrusion to retract from the through hole of the large-end interface 2113 into the interior of the small-end interface 2114, thereby releasing the protrusion from its jamming between the small-end interface 2114 and the large-end interface 2113. It is understood that the elastic element and the protrusion can be replaced with other reset elements with reset functions, which will not be elaborated upon here.

[0164] In one embodiment, the seat frame 2110 may also be formed by connecting two or more tubes through welding or other means, or it may be an integrally formed component, thereby forming a closed or open rectangular, elliptical, circular or other configuration.

[0165] The connector 2120 can be connected and fastened to the seat frame 2110 by a first fastener 2130, such as a screw. The connector 2120 can also be fixedly connected to the seat frame 2110 by riveting, welding, etc., but this disclosure is not limited thereto.

[0166] like Figure 24 and Figure 26As shown, a locking plug 2121 can be provided on the plug socket 2120. The locking plug 2121 can be provided on the surface of the plug socket 2120 that engages with the connector 2210.

[0167] In one embodiment, the plug-in 2120 is inserted into the connector 2210 in a substantially front-to-back direction. For stability and aesthetic reasons, the plug-in 2120 and the connector 2210 may have complementary mating surfaces so that they fit together tightly after being inserted.

[0168] The locking insert 2121 can extend rearward from the connector 2120. The engagement slot 2211 of the connector 2210 is positioned corresponding to the position of the locking insert 2121 and is optionally provided on the surface of the connector 2210 that engages with the connector 2120. In one embodiment, the engagement slot 2211 can have a front opening facing the child seat 20 for the locking insert 2121 to be inserted therein from front to rear.

[0169] It is understood that, in another embodiment, the insertion slot 2211 may open toward the rear opening of the child seat 20 or in another direction, and the locking plug 2121 may extend from the insertion seat 2120 toward the front or in another corresponding direction so as to be inserted into the insertion slot 2211 in the forward direction or in another corresponding direction.

[0170] Optionally, the connector 2120 has a concave arcuate connector surface 2129, and the connector 2210 has a convex arcuate mating surface 2218 corresponding to the arcuate connector surface 2129. The concave arcuate connector surface 2129 may have a first concave section 2129a facing rearward and a second concave section 2129b facing downward. The locking insert 2121 can extend rearward from the first concave section 2129a of the arcuate connector surface 2129. Correspondingly, the convex arcuate mating surface 2218 may have a first convex section 2218a facing forward and a second convex section 2218b facing upward. The mating groove 2211 may be provided in the first convex section 2218a of the arcuate mating surface 2218. After the connector 2120 is inserted into the connector 2210 and positioned appropriately, the locking insert 2121 is inserted into the mating slot 2211. The arc-shaped insertion surface 2129 and the arc-shaped mating surface 2218 fit together, ensuring that the outer surfaces of the connector 2120 and the connector 2210 are tightly connected and flush. The specific structure of the locking insert 2121 and the mating slot 2211 will be described in detail below. In this embodiment, the first concave section 2129a and the first convex section 2218a are inclined relative to the vertical direction, and the second concave section 2129b and the second convex section 2218b are approximately parallel to the horizontal direction. In other embodiments, the first concave section 2129a and the first convex section 2218a may also be approximately parallel to the vertical direction. Alternatively, in other embodiments, the second concave section 2129b and the second convex section 2218b may also be inclined relative to the horizontal direction.

[0171] The joystick 2220 may also include a joystick operating member 2221 and a locking hole 2223. The locking hole 2223 is provided on the inner side of the joystick 2220 for receiving the support rod 2230. First reset members 2231 may be provided at both ends of the support rod 2230 to securely connect the joystick 2220 and the support rod 2230. The joystick operating member 2221 is used to switch the joystick 2220 and the support rod 2230 from a locked, securely connected state to a disassembled state. That is, both ends of the support rod 2230 can be detachably connected to the joystick 2220, which will be described in detail later.

[0172] See Figure 25The diagram shows a side view of the child seat 20 in a stationary state on the support surface. Both the plug-in seat 2120 and the connecting seat 2210 extend along a first direction, which forms an angle α with the vertical direction perpendicular to the support surface. This angle α can be between 10° and 45°, which helps the child seat 20 maintain a forward-lower, rear-higher posture when stationary after installation. The seat frame 2110 of the seat assembly 2100 forms an angle β with the front-rear direction, optionally between 10° and 45°, allowing the child to comfortably lie within the child seat 20. Preferably, in one embodiment, after the seat assembly 2100 and the base frame assembly 2200 are installed, the connecting seat 2210 and the plug-in seat 2120 are positioned with an upward-sloping posture, while the seat frame 2110 is positioned with a forward-lower, rear-higher posture. Alternatively, the connection between the connector 2120 and the seat assembly 2110 is offset from the connection between the connector 2210 and the rocker arm 2220 in the front-rear direction. For example, the connection position between the connector 2120 and the seat assembly 2110 can be further forward than the connection position between the connector 2210 and the rocker arm 2220. This arrangement allows the seat assembly 2100 to have a tilted posture that is lower in the front and higher in the back, suitable for infants and young children, while also ensuring that the seat assembly 2100 has more stable support. Preferably, in one embodiment, the angle θ formed by the front side of the connector 2120 and the extended surface of the seat frame 2110 is an acute angle. Since the connection between the connector 2120 and the seat frame 2110 is close to the longitudinal front part of the seat frame 2110, this arrangement prevents the seat assembly 2100 from causing excessive shear stress on the connector 2120 during use, thereby improving the overall service life of the child seat 20.

[0173] The seat assembly 2100 can be inserted into the base frame assembly 2200 along a second direction, which intersects with the first direction. Optionally, the second direction is parallel to the fore-and-aft direction of the child seat 20, in which case the acute angle formed by the second direction and the first direction is between 45° and 80°. Of course, the second direction can also form a certain angle with the fore-and-aft direction, for example, the acute angle formed by the second direction and the fore-and-aft direction is between 0° and 45°, and this disclosure is not limited thereto.

[0174] When the child seat 20 is stationary, the front-to-back projection length of the seat frame 2110 on the support surface can be slightly smaller than the front-to-back projection length of the two rocker arms 2220 on the support surface, which is beneficial to the overall stability of the child seat 20.

[0175] See Figure 26The locking plug 2121 can extend from the socket 2120 along a second direction. Specifically, the locking plug 2121 can extend outward from the arc-shaped socket surface 2129 along the second direction. Optionally, the locking plug 2121 can extend from the socket 2120 in a front-rear direction, or its extension direction can be at an angle to the front-rear direction.

[0176] In one embodiment, the locking plug 2121 may include a locking protrusion 2122 extending from the body of the locking plug 2121. The locking protrusion 2122 may form a limiting portion 2123 at its extension portion that contacts the body for engaging and locking with a corresponding engaging structure, which will be described in detail below.

[0177] In one embodiment, the locking insert 2121 may further include a support arm 2124, a locking protrusion 2122 may be disposed at the end of the support arm 2124, and have an extension portion that expands from the end. The extension portion is formed, for example, by increasing the size in a first direction. The locking protrusion 2122 may form a limiting portion 2123 at its extension portion that engages with the support arm 2124. The support arm 2124 extends from the socket 2120 and extends along a second direction. Because the support arm 2124 is elongated, it has a certain degree of deformability, so that when the locking insert 2121 is inserted into the mating groove 2211, the support arm 2124 can elastically deform to provide clearance if necessary.

[0178] In one embodiment, the locking plug-in 2121 may further include a locking part 2125, which may also be provided with a first engagement hole 2126a and a second engagement hole 2126b for engaging and locking with the corresponding engagement structure, which will be described in detail below.

[0179] See Figure 27 The diagram shows a perspective view of the base assembly 2200. The connecting seat 2210 may include an outer cover 2210a arranged laterally on the outer side and an inner cover 2210b arranged laterally on the inner side. The outer cover 2210a has an outwardly opening button slot 2213. Figure 27 In the example shown, the button slot 2213 is located on the lateral outer side of the outer cover 2210a to facilitate button operation. The release actuation element 2240 may be located on the connector 2210 and at least partially accommodated in the button slot 2213.

[0180] Specifically, such as Figure 28The internal structure of the connecting seat 2210 after removing the inner cover 2210b is shown. In one embodiment, the release operation member 2240 may include a pivot 2242 and operation portions 2241 and engaging portions 2244 located on both sides of the pivot 2242. The portion of the operation portion 2241 exposed outside the outer cover 2210a may be rectangular, elliptical, or other shapes, and may optionally be provided with a corrugated or anti-slip coating to facilitate user pressing operation. The size and shape of the operation portion 2241 may match the size and shape of the button slot 2213 for installation within the button slot 2213. The operation portion 2241 and engaging portions 2244 may, for example, be located on the front and rear sides of the pivot 2242, respectively. A first engaging member 2244a and a second engaging member 2244b may be provided in a second direction on the engaging portion 2244. The first engaging member 2244a and the second engaging member 2244b can be formed as hook-shaped protrusions protruding toward the locking insert 2121 inserted into the engagement slot 2211 of the connector 2210. The first engaging member 2244a and the second engaging member 2244b can each have a slope that is inclined from the inside of the connector 2210 toward the outside of the connector 2210 in a second direction, so as to engage with the first engaging hole 2126a and the second engaging hole 2126b of the locking insert 2121 in the locked state, and to disengage from these engaging holes in the unlocked state. This will be described in detail below.

[0181] The interior of the connecting seat 2210 may also have reinforcing ribs 2216 and guide ribs 2217. The reinforcing ribs 2216 can strengthen the structural strength of the connecting seat 2210, and the guide ribs 2217 can not only strengthen the structural strength of the connecting seat 2210, but also limit and guide the release operation member 2240 and the locking plug 2121.

[0182] The pivot shaft 2242 is located within the pivot groove 2212 defined by the guide rib 2217, and the pivot shaft 2242 can rotate within the pivot groove 2212. The axial direction of the pivot shaft 2242 can be arranged along a first direction or along other directions, and this disclosure is not limited in this regard. Thus, by applying a pressing force toward the lateral inward side to the operating part 2241, the engaging part 2244 can pivot outward about the pivot shaft 2242, thereby disengaging the first engaging member 2244a and the second engaging member 2244b of the engaging part 2244 from the first engaging hole 2126a and the second engaging hole 2126b of the locking plug 2121.

[0183] In one embodiment, a plurality of connecting posts 2214 may be provided on the outer cover 2210a. The connecting posts 2214 can be positioned at any location on the outer cover 2210a according to the structural layout requirements of the connecting seat 2210; optionally, they can be arranged at the edge or center of the outer cover 2210a. In one embodiment, the connecting posts 2214 may be distributed along the edge of the outer cover 2210a. The connecting posts 2214 may extend away from the inner surface of the outer cover 2210a in a direction perpendicular to the inner surface of the outer cover 2210a. In this embodiment, the connecting posts 2214 are hollow cylindrical structures. It is understood that the connecting posts 2214 may also be formed as solid cylinders.

[0184] See Figures 29-30 Specifically, it shows the structure and connection relationship of the plug-in 2120, the connector 2210, and the release operation member 2240 according to an embodiment of the present disclosure, wherein the locking plug 2121 of the plug-in 2120 and the release operation member 2240 constitute a locking and unlocking structure. Figure 29 and Figure 30 The corresponding changes in the engagement and disengagement structure are shown when the child seat 20 is in the locked state and the unlocked state, respectively.

[0185] In one embodiment, the release operation member 2240 may further include a second reset member 2243. One end of the second reset member 2243 is connected to the engaging portion 2244, and the other end can be fixed to a certain position within the connecting seat 2210. The second reset member 2243 applies an elastic force to the engaging portion 2244, causing the release operation member 2240 to tend to hold the engaging portion 2244 in a locked position where it engages with the engaging hole of the locking insert 2121. The second reset member 2243 may be a coil spring, a leaf spring, or other elastic element.

[0186] exist Figure 29In this embodiment, the child seat 20 is in a locked state. In one embodiment, the locking insert 2121 enters the connecting seat 2210 via the insertion slot 2211 in the second direction (i.e., moving backward). The first engaging hole 2126a of the locking insert 2121 first engages with the second engaging member 2244b of the engaging part 2244. Further pushing the locking insert 2121 inward causes the first engaging hole 2126a to disengage from the second engaging member 2244b and continue moving into the connecting seat 2210 until the locking part 2125 abuts against the guide rib 2217, preventing the locking insert 2121 from moving backward in the second direction. At this point, the first engaging hole 2126a engages with the first engaging member 2244a, and the second engaging hole 2126b engages with the second engaging member 2244b, preventing the locking insert 2121 from moving forward in the second direction and thus preventing it from disengaging from the connecting seat 2210. That is, the locking plug 2121 engages with the first engaging member 2244a and the second engaging member 2244b of the engaging part 2244 through the first engaging hole 2126a and the second engaging hole 2126b, and the locking part 2125 abuts against the guide rib 2217, so that the locking plug 2121 cannot move in the second direction and thus cannot disengage from the connecting seat 2210. It can be understood that only one engaging hole or more than two engaging holes can be provided, and corresponding engaging members can be provided. It can also be understood that the number of engaging holes and engaging members can be inconsistent. The insertion groove 2211 can also restrict the downward movement of the locking plug 2121. In addition, the locking plug 2121 can be restricted to slide along the insertion direction or move up and down by designing a corresponding guide rib 2217 in the connecting seat 2210.

[0187] When the child seat 20 is locked, the release operation member 2240 is constantly subjected to the force applied by the second reset member 2243, and the first engaging member 2244a and the second engaging member 2244b can be engaged with the first engaging hole 2126a and the second engaging hole 2126b, thereby keeping the locking plug 2121 engaged with the release operation member 2240.

[0188] exist Figure 30 In the unlocked state, the child seat 20 is in the unlocked position. In one embodiment, pressing the operating part 2241 of the unlocking operation member 2240 causes the operating part 2241 to move towards the interior of the connecting seat 2210 around the pivot axis 2242, and drives the engaging part 2244 to move towards the exterior of the connecting seat 2210 against the force applied by the second reset member 2243, until the first engaging member 2244a and the second engaging member 2244b disengage from the first engaging hole 2126a and the second engaging hole 2126b. This causes the locking plug 2121 to disengage from the unlocking operation member 2240. At this time, the locking plug 2121 can move outward (i.e., forward) from the connecting seat 2210 along the second direction via the insertion groove 2211.

[0189] Figure 31 This is a side sectional view of a base assembly 2200 according to an embodiment of the present disclosure, showing the internal structure of the connecting seat 2210. The connecting seat 2210 can be connected and fastened to the rocker arm 2220 by a second fastener 2250, such as a screw. The connecting seat 2210 can also be fixedly connected to the rocker arm 2220 by riveting, welding, etc., or be integrally formed with the rocker arm 2220, but the present disclosure is not limited thereto. In particular, Figure 31 A welded structure is also shown. This welded structure may include a connecting column 2214 and a sleeve 2215.

[0190] Multiple sleeves 2215 may be provided on the inner cover 2210b, each corresponding to a connecting post 2214 on the outer cover 2210a of the connecting seat 2210. In one embodiment, the sleeves 2215 may be evenly distributed along the edge of the inner cover 2210b. The sleeves 2215 may extend away from the inner surface of the inner cover 2210b in a direction perpendicular to the surface of the inner cover 2210b. The sleeves 2215 may be formed as hollow cylinders. The connecting posts 2214 may be inserted into the sleeves 2215 with an interference fit, so that the inner cover 2210b and the outer cover 2210a can be fastened together. Multiple welding ribs or welding protrusions may also be additionally provided on the inner surface of the sleeves 2215 to fix the inner cover 2210b and the outer cover 2210a together, but this disclosure is not limited thereto. By connecting the column 2214 and the sleeve 2215, welding energy consumption can be greatly reduced while ensuring welding strength.

[0191] It is understandable that the sleeve can also be set on the outer cover 2210a, and the connecting post 2214 is correspondingly set on the inner cover 2210b, so as to realize the snap-fit ​​fixation of the outer cover 2210a and the inner cover 2210b.

[0192] It is understood that the fastening and fixing between the connecting post 2214 and the sleeve 2215 of this disclosure can also be replaced or additionally fixed by other known fixing methods such as screws, rivets, and welding.

[0193] Figure 31 A support rod detachment structure is also shown. This structure may include a rocker arm operating component 2221 and a support rod 2230. The rocker arm operating component 2221 may be disposed in a mounting groove 2222 on the top surface of the rocker arm 2220. The outer surface of the rocker arm operating component 2221 is approximately flush with or slightly lower than the top surface of the rocker arm 2220, making the overall appearance of the child seat 20 more aesthetically pleasing and preventing accidental operation by the user.

[0194] The inner surface of the rocker arm operating member 2221 facing the mounting groove 2222 may have a protrusion 2228 for abutting against the first reset member 2231 on the support rod 2230. The rocker arm operating member 2221 deforms downwards after being subjected to downward pressure and returns to its original position after the pressure is removed. The rocker arm operating member 2221 may be a leaf spring or other elastic element, and this disclosure is not limited thereto. The support rod 2230 may be formed as a rod with a non-circular cross-section, and the size and shape of the retaining hole 2223 of the rocker arm 2220 for receiving the support rod 2230 are formed to match the support rod 2230. In one embodiment, the cross-sectional profile of the support rod 2230 may be formed as a shape composed of arcs and chords, so that the support rod 2230 is aligned with the retaining hole 2223 when installed on the rocker arm 2220 and cannot rotate relative to it after installation. The cross-sectional profile of the support rod 2230 is not limited to this, and can also have cross-sectional profiles such as inverted triangle, rectangle, ellipse, hexagon.

[0195] The first reset member 2231 may be an elastic pin or an elastic body made of elastic material, and this disclosure is not limited thereto. It is capable of moving between the protruding and retracting circumferential walls of the support rod 2230. A slot 2229 may be provided at the top of the circumferential wall of the locking hole 2223 to accommodate the first reset member 2231 protruding from the circumferential wall of the support rod 2230. When both ends of the support rod 2230 are inserted into the locking holes 2223 of the rocker arm 2220, the first reset members 2231 at both ends of the support rod 2230 are constrained by the inner peripheral wall of the locking hole 2223 and can overcome the elastic force to retract inward until the support rod 2230 is inserted into the predetermined position in the locking hole 2223. At this time, the first reset member 2231 is located at the locking hole groove 2229, the constraint of the inner peripheral wall of the locking hole 2223 on the first reset member 2231 disappears, and the first reset member 2231 extends into the locking hole groove 2229 under the action of elastic force, thereby engaging and connecting the support rod 2230 and the rocker arm 2220. It can be understood that the first reset member 2231 can be replaced by one or more other reset elements with reset function, which will not be elaborated here. To disassemble the support rod 2230 from the rocker arm 2220, the user can press down on the rocker arm operating member 2221. The protrusion 2228 moves downward, abutting against the first reset member 2231 and retracting it into the support rod 2230, thereby removing the first reset member 2231 from the locking slot 2229. At this point, the support rod 2230 and the rocker arm 2220 disengage, and the support rod 2230 can be pulled out of the locking hole 2223, thus disconnecting the support rod 2230 from the rocker arm 2220. Therefore, the base frame assembly 2200 can be disassembled, and the support rod 2230 and the rocker arm 2220 can be packaged or stored separately for convenient transportation or storage.

[0196] refer to Figure 32This illustration shows a perspective view of a seat assembly 2100 according to one or more of the above embodiments mounted on a high chair 2300 according to another embodiment of this disclosure. A user can disassemble the seat assembly 2100 and the base assembly 2200 of the child seat 20 according to one or more of the above embodiments and mount the seat assembly 2100 onto the high chair 2300 to form a child seat 20 with a certain height, facilitating feeding of the child by a caregiver. It is understood that the seat assembly 2100 can also be mounted on other carriers or support assemblies, and this application is not limited thereto.

[0197] Continue to refer to Figure 33 The diagram illustrates the engagement and disengagement structure of the seat assembly 2100 and the high chair 2300. The high chair 2300 may include a first leg 2310, a second leg 2320, an arm 2330, and a connecting seat 2340. The connecting seat 2340 may be located at the junction of the first leg 2310 and the arm 2330. When the seat assembly 2100 is installed onto the high chair 2300, the insertion seat 2120 and the connecting seat 2340 are connected via the engagement and disengagement structure. The following description only details the differences between the engagement and disengagement structure of this embodiment and the above embodiments; similarities or identical aspects will be omitted.

[0198] The locking insert 2121 is inserted into the connecting seat 2340 along the second direction via the engagement groove 2341. When the locking protrusion 2122 enters the engagement groove 2341, the support arm 2124 can elastically deform and move upward to provide clearance, allowing the locking protrusion 2122 to enter the engagement groove 2341 more smoothly. When the locking insert 2121 enters the predetermined position within the connecting seat 2340, the support arm 2124 can elastically deform and return to its original position, causing the locking protrusion 2122 to move downward, thereby engaging the limiting part 2123 with the limiting step 2342 on the first leg 2310. The side wall of the connecting seat 2340 can guide and limit the locking insert 2121. In one embodiment, a stop part 2343 can also be formed inside the connecting seat 2340, which, together with the side wall of the connecting seat 2340, can limit the locking part 2125. The abutment portion 2127, which abuts against the stop portion 2343, can limit the locking plug 2121 in the second direction, but the abutment portion 2127 can move vertically without being restricted by the stop portion 2343. When the locking plug 2121 reaches the fully inserted position, the locking protrusion 2122 can be arranged on the outside of the high chair 2300. In one embodiment, in order to separate the seat assembly 2100 from the high chair 2300, an upward force is applied to the locking protrusion 2122 exposed on the outside of the high chair 2300. This force causes the locking protrusion 2122 to bend toward the locking portion 2125, causing the limiting portion 2123 to disengage from the limiting step 2342, thereby facilitating the separation of the seat assembly 2100 from the high chair 2300.

[0199] The term “approximately” is intended to include the degree of error associated with a specific number of measurements based on the number of devices available at the time of application submission.

[0200] Figures 34-47 Several embodiments and variations of this disclosure are illustrated schematically, but are merely for illustrating the technical concept of this disclosure and are not intended to limit the scope of protection of this disclosure.

[0201] refer to Figure 34 and Figure 35 The image shows a perspective view of a children's rocking chair 30 according to an embodiment of the present disclosure, wherein the children's rocking chair 30 is in a mounted position.

[0202] Specifically, Figure 34 A child rocking chair 30 is shown as viewed from the front. The child rocking chair 30 may include a seat assembly 3100 and a base frame assembly 3200 that supports the seat assembly 3100.

[0203] Seat assembly 3100 is used to support and mount a seat or seat cover for placing a child on the seat or seat cover for rocking and playing. Seat assembly 3100 can be mounted above or directly above base assembly 3200. Seat assembly 3100 may include seat frame 3110 and connector 3120, wherein seat frame 3110 is used to support and mount the seat or seat cover. Seat frame 3110 may be located above connector 3120. Seat frame 3110 may be formed by connecting multiple tubing components by welding or other means, or it may be integrally formed, thereby forming a closed or open rectangle, ellipse, circle, etc. Seat frame 3110 may be fixedly connected to connector 3120 by riveting, welding, etc., or the two may be integrally formed, but this disclosure is not limited thereto. Connector 3120 extends from seat frame 3110 toward base assembly 3200, in other words, extends downward along a first direction. The width of the upper surface of the connector 3120 can optionally match the width of the lower surface of the seat frame 3110. The connector 3120 can be fixed to both sides of the seat frame 3110, located slightly below the center along the longitudinal direction of the seat frame 3110, to facilitate the overall forward-leaning posture of the child rocker 30 when stationary. For example, the midpoint of the connection point between the connector 3120 and the seat frame 3110 is located within the range of the first 1 / 4 to 1 / 2 of the length of the seat frame 3110.

[0204] The base assembly 3200 may include a connecting seat 3210, rocker arms 3220, and a support rod 3230. Two rocker arms 3220 may be respectively positioned on the left and right sides of the child rocking chair 30. Each rocker arm 3220 may be an arc-shaped rod, allowing for back-and-forth rocking motion when placed on the ground. The connecting seat 3210 may be located above the rocker arms 3220. The connecting seat 3210 may be fixedly connected to the rocker arms 3220 by riveting, welding, or other means, or may be integrally formed with the rocker arms 3220, but this disclosure is not limited thereto. The width of the lower surface of the connecting seat 3210 may optionally match the width of the upper surface of the rocker arms 3220. The connecting seat 3210 may extend from the upper surface of the rocker arms 3220 toward the seat assembly 3100, in other words, also extend upward along a first direction. The connecting seat 3210 may be fixed approximately at the midpoint of the longitudinal direction of the rocker arms 3220. For example, the midpoint of the connection position between the connector 3210 and the rocker arm 3220 is located within the range of the first 1 / 3 to 1 / 2 of the length of the rocker arm 3220. Optionally, the first direction forms an angle α with the vertical direction, and this angle α is between 10° and 45° (see [reference]). Figures 44A-44B This helps the rocking chair 30 maintain a forward-leaning posture when stationary after installation. The support rod 3230 can be positioned between the two rocking arms 3220 on either side of the rocking chair 30, with both ends of the support rod 3230 fixedly connected to the rocking arms 3220. The support rod 3230 can be one, two, or more, depending on the robustness of the base frame assembly 3200. The seat frame 3110 of the seat assembly 3100 forms an angle β with the fore-and-aft direction; optionally, this angle β is between 10° and 45° (see [reference]). Figures 39A-39B This design allows children to comfortably lie supine within the child rocker 30. Preferably, in one embodiment, after the seat assembly 3100 and the base frame assembly 3200 are installed, in the rear-to-front direction, the insertion seat 3120 and the connecting seat 3210 extend upwards at an angle, while the seat frame 3110 extends downwards at an angle. Alternatively, the connection between the insertion seat 3120 and the seat assembly 3110 and the connection between the connecting seat 3210 and the rocker arm 3220 are offset from each other in the front-to-back direction. This arrangement allows the seat assembly 3100 to have a downward-sloping orientation suitable for infants and toddlers, while also providing good support. Preferably, in one embodiment, the angle formed by the front side of the connection between the insertion seat 3120 and the seat frame 3110 is an acute angle, or the angle θ formed by the front side of the upper end of the insertion seat 3120 and the seat frame 3110 is an acute angle (e.g., ...). Figures 44A-44B As shown, since the connection between the connector 3120 and the seat frame 3110 is close to the longitudinal front part of the seat frame 3110, this arrangement ensures that the seat assembly 3100 will not cause excessive shear stress to the connector 3120 during use, thereby improving the overall service life of the child rocking chair 30.

[0205] The seat assembly 3100 and the base frame assembly 3200 are detachably connected via a locking and unlocking structure between the insertion socket 3120 and the connecting socket 3210. Specifically, the seat assembly 3100 can be inserted into the base frame assembly 3200 along a second direction, such as... Figures 39A-39C As shown, the second direction intersects with the first direction. Optionally, the second direction is parallel to the front-back direction of the child rocking chair 30, in which case the acute angle formed by the second direction and the first direction is between 45° and 80°. Of course, the second direction can also form a certain angle with the front-back direction, for example, the acute angle formed by the second direction and the first direction is between 0° and 30°, and this disclosure is not limited thereto. The shape of the lower surface of the plug-in seat 3120 can optionally match the shape of the upper surface of the connecting seat 3210. When the plug-in seat 3120 is plugged into the connecting seat 3210, the circumferential wall of the plug-in seat 3120 is flush with the circumferential wall of the connecting seat 3210, making the product more aesthetically pleasing.

[0206] When the child rocking chair 30 is stationary, the front-to-back projection length of the seat frame 3110 on the horizontal plane can be slightly smaller than the front-to-back projection length of the rocker arm 3220 on the horizontal plane (see...). Figures 39A-39B (44A-44B, 45A-45C), the lateral projection length of the seat frame 3110 on the horizontal plane can be equal to, slightly less than, or slightly greater than the lateral projection length of the rocker arm 3220 on the horizontal plane (see...). Figures 34-35 This contributes to the overall stability of the children's rocking chair 30.

[0207] Figure 35 A child rocking chair 30 is shown as viewed from the rear. In one embodiment, a release operation 3240 is provided on the rear side of the connecting seat 3210 facing longitudinal rearward. The release operation 3240 may be disposed within an outwardly opening button groove 3213 of the connecting seat 3240. The release operation 3240 may be located approximately in the middle of the rear side of the connecting seat 3210 in the vertical direction for easy operation by the user. When the child rocking chair 30 is locked, the outer surface of the release operation 3240 is approximately flush with the outer surface of the connecting seat 3210 (see [reference]). Figure 39A , 44A -44B, 45A-45C) make the overall appearance of the children's rocking chair 30 more aesthetically pleasing, while also preventing improper operation caused by accidental contact by the user. In other embodiments, the release operation member 3240 may be located in other positions.

[0208] refer to Figures 36-37The illustration shows a disassembled child rocker 30 according to an embodiment of the present disclosure. A locking insert 121 is disposed on and fixedly connected to a connector 3120. The locking insert 121 may be disposed on the surface where the connector 3120 engages with the connecting seat 3210. The locking insert 121 may extend from the connector 3120 in a second direction, optionally in a front-rear direction, or its extension direction may be at an angle to the front-rear direction. The locking insert 121 may be provided with a locking protrusion 31211. In one embodiment, the locking insert 121 may include a locking protrusion 31211 extending from the body of the locking insert 121. The locking protrusion 31211 may form a limiting portion 31212 at its extension portion that engages with the limiting step 3251 of the locking member 3250 (see [link to documentation]). Figure 39A The following will describe this in detail. The position of the engagement slot 3211 corresponds to the position of the locking plug 121, and is optionally disposed on the surface of the connector 3210 that engages with the connector 3120. In one embodiment, the engagement slot 3211 may open towards the front of the rocking chair 30 for the locking plug 121 to be inserted therein in a rearward direction. It is understood that in another embodiment, the engagement slot 3211 may open towards the rear of the rocking chair 30 or in other directions for the locking plug 121 to be inserted therein in a forward or other direction. Optionally, the locking plug 121 may further include a support arm 31213, with a locking protrusion 31211 disposed at the end of the support arm 31213. The locking protrusion 31211 may form a limiting portion 31212 at its extension portion that engages with the support arm 31213. The support arm 31213 extends from the connector 3120 and extends along a second direction. Because the support arm 31213 is elongated, it has a certain degree of deformation elasticity, which allows the support arm 31213 to elastically deform to provide clearance when the locking plug 121 is inserted into the mating groove 3211, so that the locking protrusion 31211 can engage more smoothly with the limiting step 3251.

[0209] Optionally, in some embodiments, the locking plug-in 121 may also include an additional locking part 31214, which may also be provided with a locking hole 31215 for engaging and locking with the locking structure of other structures, thereby enabling the seat assembly 3100 to be installed and locked with other structures to increase the versatility of the seat assembly 3100.

[0210] Optionally, the connector 3120 has a concave arc-shaped insertion surface 3122, and the connector 3210 has a convex arc-shaped mating surface 3218 corresponding to the arc-shaped insertion surface 3122. When the connector 3120 is inserted into the connector 3210, the arc-shaped insertion surface 3122 and the arc-shaped mating surface 3218 cooperate, making the surfaces of the connector 3120 and the connector 3210 flush. The locking plug 121 extends outward from the arc-shaped insertion surface 3122 along a second direction.

[0211] See Figure 38 and Figures 39A-39C Specifically, it illustrates the structure and connection relationship of the plug-in 3120, the connector 3210, the release operation member 3240 and the locking member 3250 according to an embodiment of the present disclosure, wherein the locking plug 121 of the plug-in 3120, the release operation member 3240 and the locking member 3250 constitute a locking and unlocking structure. Figure 39A , 39B Figures 39C and 39C respectively show the corresponding changes in the locking and unlocking structure when the child rocking chair 30 is in the locked, unlocked, and disassembled states.

[0212] Specifically, such as Figure 38As shown, in one embodiment, the unlocking operation member 3240 may include an operating portion 3241, a connecting rod 3242, and a driving protrusion 3244. The outward-facing plane of the operating portion 3241 may be rectangular, elliptical, or other shapes, and may be provided with a corrugated or anti-slip coating to facilitate user pressing operation. The operating portion 3241 and the driving protrusion 3244 may be respectively provided at both ends of the connecting rod 3242. The connecting rod 3242 may extend longitudinally from the bottom of the operating portion 3241, and the connecting rod 3242 may be formed as a rectangular rod. The driving protrusion 3244 may extend laterally from the end of the connecting rod 3242 away from the operating portion 3241, and the driving protrusion 3244 may be formed as a cylinder. The locking member 3250 may include a driving groove 3252 that mates with the driving protrusion 3244, and the driving groove 3252 may be an elongated groove. Therefore, by applying a force to the operating part 3241, the connecting rod 3242 can be driven to slide along the second direction, thereby causing the driving protrusion 3244 to slide relative to the driving groove 3252, and further driving the locking member 3250 to move between the locked position and the unlocked position along a third direction, which is different from the second direction. Optionally, the unlocking operating member 3240 may also include a reset member 3243. One end of the reset member 3243 is connected to the operating part 3241, and the other end can be connected to a corresponding position in the connecting seat 3210. The reset member 3243 applies an elastic force to the operating part 3241, so that the unlocking operating member 3240 tends to hold the locking member 3250 in the locked position. The reset member 3243 can be a coil spring, a leaf spring, or other elastic element. In this embodiment, the locking member 3250 moves linearly along the third direction, wherein the third direction intersects with the second direction. In other embodiments not shown, the locking member 3250 can switch between the locked and unlocked positions in a non-linear manner along a third direction (e.g., clockwise or counterclockwise).

[0213] In other embodiments not shown, the release mechanism 3240 may also exclude the linkage 3242, such that a drive protrusion 3244 is formed on one side of the operating part 3241, allowing the driving protrusion 3244 to slide relative to the drive groove 3252 when a force is applied to the operating part 3241. In this case, the reset member 3243 can be connected between the connecting seat 3210 and the locking member 3250, and directly apply an elastic force to the locking member 3250, causing the locking member 3250 to tend to remain in the locked position.

[0214] like Figure 38 and Figures 39A-39CAs shown, in one embodiment, a button groove 3213 is formed on the connector 3210, and the position of the button groove 3213 is opposite to the position of the mating groove 3211 in the longitudinal direction. In one embodiment, the button groove 3213 may be located on the back side of the connector 3210. The size and shape of the button groove 3213 may match the size and shape of the operating part 3241. A guide rib 3217 is also formed inside the connector 3210, which can not only strengthen the structural strength of the connector 3210, but also limit and guide the release operating member 3240, the locking member 3250 and the locking plug 121 (see...). Figure 38 , Figures 39A-39C , Figures 40-41 45A-45C).

[0215] Figures 39A-39C The connection and relative movement relationship of the connecting base 3210, the release operation member 3240, the locking member 3250 and the locking plug 121 are shown. The locking member 3250 can be slidably disposed on the release operation member 3240, so that the release operation member 3240 can drive the locking member 3250 to slide within the connecting base 3210, thereby the locking member 3250 can move between the locking position engaged with the locking plug 121 and the unlocking position disengaged from the locking plug 121.

[0216] In one embodiment, the locking member 3250 is slidably disposed inside the connecting seat 3210 via guide ribs 3217 on the inner surface of the connecting seat 3210, and the guide ribs 3217 can also limit the locking member 3250. Specifically, the locking member 3250 can slide along a third direction by means of the fifth guide rib 32175, the seventh guide rib 32177 and the eighth guide rib 32178, while the third guide rib 32173 and the sixth guide rib 32176 restrict or support it on the upper and lower sides of its sliding direction, respectively.

[0217] In some embodiments, the locking member 3250 may optionally include a limiting groove 3253, which may also be an elongated groove. The limiting groove 3253 is disposed along the sliding direction of the locking member 3250, that is, extending along a third direction. The limiting groove 3253 and the extending direction of the driving inclined groove 3252 form an angle γ. Optionally, the angle γ is between 40° and 70° (e.g., Figure 41(As shown). Accordingly, a limiting protrusion 3212 can also be formed inside the connecting seat 3210. The limiting protrusion 3212 can be formed as a boss that matches the shape of the limiting groove 3253. The length of the limiting protrusion 3212 is less than the length of the limiting groove 3253, so that the locking part 3250 can slide relative to the limiting protrusion 3212 in a third direction. The limiting groove 3253 of the locking part 3250 can engage with the limiting protrusion 3212, and the locking part 3250 can slide relative to the limiting protrusion 3212 along the limiting groove 3253. Through the cooperation of the limiting groove 3253 and the limiting protrusion 3212, the guiding and limiting functions of the locking part 3250 can be realized. It is understood that, in the embodiments of this disclosure, in order to guide and limit the locking member 3250, only the limiting groove 3253 and the limiting protrusion 3212 may be provided, without the guide rib 3217 for the locking member 3250; or only the corresponding guide rib 3217 for the locking member 3250 may be provided, without the limiting groove 3253 and the limiting protrusion 3212; of course, both the limiting groove 3253 and the limiting protrusion 3212 and the guide rib 3217 for the locking member 3250 may be provided.

[0218] The operating part 3241 passes through the button slot 211 to push the connecting rod 3242 to slide within the connecting seat 3210, and the driving protrusion 3244 and the driving inclined groove 3252 are slidably engaged. The operating part 3241 and the connecting rod 3242 can be guided to slide by means of corresponding ribs (such as the fourth guide rib 32174) within the connecting seat 3210. The locking plug 121 passes through the insertion slot 3211 into the interior of the connecting seat 3210, and can be guided to slide by means of corresponding ribs (such as the first guide rib 32171, the third guide rib 32173, and the ninth guide rib 32179) within the connecting seat 3210.

[0219] In some embodiments not shown in the figures, the locking member 3250 includes only the limiting groove 3253 and not the driving inclined groove 3252. In this case, the release operation member 3240 is directly formed on one side of the locking member 3250, and the movement direction of the release operation member 3240 is the same as that of the locking member 3250, that is, both move along the third direction. When a force is applied to the release operation member 3240, the release operation member 3240 directly drives the locking member 3250 to switch between the locked position and the released position along the third direction. In this case, the reset member 3243 is directly disposed between the connecting seat 3240 and the release operation member 3240.

[0220] exist Figure 39AIn the middle, the child rocking chair 30 is in the locked state. At this time, the locking plug 121 enters the connecting seat 3210 through the insertion groove 3211. The locking protrusion 31211 of the locking plug 121 forms an abutment part 31216 on the side away from the limiting part 31212, and a mating part 3254 is formed on the side of the locking member 3250 away from the limiting step 3251 (e.g., Figure 38 As shown, when the locking plug 121 is inserted into the connecting seat 3210, the abutting part 31216 of the locking plug 121 abuts against the mating part 3254 of the locking member 3250, so as to drive the locking member 3250 to move a distance toward the unlocking position to avoid the locking plug 121, thereby realizing the engagement of the limiting part 31212 and the limiting step 3251. That is, the locking plug 121 engages with the limiting step 3251 of the locking member 3250 through the limiting part 31212 of the locking protrusion 31211, so that the locking plug 121 cannot move forward in the second direction (i.e., toward the front of the child rocking chair 30), and thus cannot be separated from the connecting seat 3210. The upper surface of the locking member 3250 can also restrict the downward movement of the locking plug 121. Furthermore, the second guide rib 32172 within the connector 3210 can restrict the locking plug 121 from continuing to slide or move up and down along the insertion direction (i.e., backward along the second direction). Optionally, the second guide rib 32172 can simultaneously abut against the locking protrusion 31211 and the additional locking portion 31214 of the locking plug 121, or the second guide rib 32172 can abut against only one of the locking protrusion 31211 and the additional locking portion 31214 of the locking plug 121. The locking protrusion 31211 can optionally be formed as an arcuate protrusion to abut against the upper surface of the locking member 3250 and slide along that upper surface. That is, the abutment portion 31216 can optionally be an arcuate convex surface on the locking protrusion 31211, which can push against the mating portion 3254 of the locking member 3250 to push the locking member 3250 toward the unlocking position during the insertion of the locking plug 121 into the 3210. The drive protrusion 3244 of the release operation member 3240 can be slidably connected with the drive groove 3252 of the locking member 3250, so that the drive protrusion 3244 can slide in the drive groove 3252. When the child rocking chair 30 is in the locked state, the release operation member 3240 is constantly subjected to the force applied by the reset member 3243, and the drive protrusion 3244 can remain abutting against the lower edge of the drive groove 3252, thereby keeping the locking member 3250 in the position engaged with the locking plug 121.

[0221] In this embodiment, the first guide rib 32171, the third guide rib 32173, the fourth guide rib 32174, the sixth guide rib 32176, and the ninth guide rib 32179 extend generally along the second direction; the fifth guide rib 32175, the seventh guide rib 32177, and the eighth guide rib 32178 extend generally along the third direction. Optionally, in the initial state where the plug-in seat 3120 and the connecting seat 3210 are not assembled, or in the locked state where the locking member 3250 is in the height direction, the upper surface of the locking member 3250 is higher than the upper surface of the ninth guide rib 32179. In this way, when the plug-in member 121 is inserted into the connecting seat 3210, the locking member 3250 can move along the third direction to avoid obstruction, and then the limiting part 31212 can engage with the limiting step 3251. Optionally, the upper surface of the ninth guide rib 32179 has an arc shape on the side near the locking member 3250, which facilitates the removal of the locking plug 121 from the connector 3210 after unlocking. Optionally, similarly, the upper surface of the locking member 3250 is higher than the upper surface of the third guide rib 32173. Specifically, in the initial state where the connector 3120 and the connector 3210 are not assembled, or in the locked state where the locking member 3250 is in the locking state, the upper surface of the locking member 3250 is higher than the upper surface of the third guide rib 32173 in the height direction.

[0222] A force is applied forward along the second direction to the unlocking operating member 3240, causing the connecting rod 3242 to slide forward along the fourth guide rib 32174, which in turn drives the driving protrusion 3244 to slide upward along the driving groove 3252, thereby causing the locking member 3250 to move downward along the third direction within the connecting seat 3210 until the locking member 3250 disengages from the locking plug 121. At this time, the child rocking chair 30 is in the unlocked state (e.g., Figure 39B (As shown). In the unlocked state, the user can apply a force to the right of the plug-in 3120 in the second direction, and the locking plug 121 can be moved away from the connector 3210 in the second direction, thereby separating the seat assembly 3100 from the base frame assembly 3200. At this time, the child rocking chair 30 is in the disassembled state (as shown). Figure 39C(As shown). Then, the release operation 3240 is released. Under the action of the reset member 3243, the release operation 3240 moves backward in the second direction, causing the connecting rod 3242 to slide backward along the fourth guide rib 32174. This, in turn, causes the drive protrusion 3244 to slide downward along the drive groove 3252, thereby causing the locking member 3250 to move upward in the third direction until the locking member 3250 reaches the locking position with the locking plug 121. Optionally, the side of the locking member 3250 facing forward in the second direction can abut against the eighth guide rib 32178 inside the connecting seat 3210. This eighth guide rib 32178 can connect with the ninth guide rib 32179 on the lower edge of the guiding locking protrusion 31211 inside the connecting seat 3210. At least a portion of the ninth guide rib 32179 is arc-shaped, which facilitates the removal of the locking protrusion 31211 from the connecting seat in the released state.

[0223] Figures 40-43 The internal structure of the connecting seat 3210 of a children's rocking chair 30 according to an embodiment of the present disclosure is shown, and in particular, a welding structure is shown. The welding structure may include a welding column 3214, a sleeve 3215, and a welding rib 3216.

[0224] Specifically, Figure 40 The diagram schematically illustrates the inner cover 3210b of the connecting seat 3210 of a child rocker 30 according to an embodiment of the present disclosure. A plurality of welded posts 3214 may be provided on the inner cover 3210b. The number of welded posts 3214 can be several, for example ten, or other numbers. The welded posts 3214 can be arranged at any position on the inner cover as needed, optionally at the edge or center of the inner cover. In one embodiment, the welded posts 3214 can be evenly distributed along the edge of the inner cover 3210b, with four welded posts 3214 arranged on each side of the inner cover 3210b, and one welded post 3214 arranged at the center of the inner cover 3210b. The welded posts 3214 can extend away from the inner surface of the inner cover 3210b in a direction perpendicular to the inner surface of the inner cover 3210b. In this embodiment, the welded posts 3214 are solid columnar structures. It is understood that the welded posts 3214 can also be formed as hollow cylinders.

[0225] Figure 41The diagram schematically illustrates the outer cover 3210a of the connecting seat 3210 of the child rocking chair 30. Multiple sleeves 3215 may be provided on the outer cover 3210a, corresponding one-to-one with the welded posts 3214 on the inner cover 3210b of the connecting seat 3210. In one embodiment, the sleeves 3215 may be evenly distributed along the edge of the outer cover 3210a, with four sleeves 3215 arranged on each side of the outer cover 3210a, and one sleeve 3215 arranged at the center of the outer cover 3210a. The sleeve 3215 at the center can support the ribs supporting the sliding of the connecting rod 3242, while the sleeves 3215 arranged on the sides of the outer cover 3210a can support the ribs supporting the operating part 3241 or the locking plug 121. The sleeves 3215 may extend in a direction perpendicular to the surface of the outer cover away from the inner surface of the outer cover. The sleeves 3215 may be formed as hollow cylinders. The inner surface of the sleeve 3215 is provided with a plurality of welding ribs 3216 or welding protrusions, but this disclosure is not limited thereto. The number of welding ribs 3216 can be four or other numbers. In one embodiment, four welding ribs 3216 are evenly distributed on the inner surface of each sleeve 3215. Through the cooperation between the welding post 3214 and the sleeve 3215, welding energy consumption can be greatly reduced while ensuring welding strength.

[0226] Understandably, the sleeve can also be set on the inner cover 3210b, and the welding post is correspondingly set on the outer cover 3210a, so as to achieve the fixed welding of the outer cover 3210a and the inner cover 3210b.

[0227] See Figure 42A , Figure 42B and Figure 43 The inner cover 3210b and outer cover 3210a of the connecting seat 3210 are fixed by a welding post 3214 and a sleeve 3215, optionally fixed by welding. In one embodiment, the welding post 3214 disposed on the inner cover 3210b of the connecting seat 3210 is inserted into the sleeve 3215 disposed on the outer cover 3210a of the connecting seat 3210, and engages with the welding rib 3216 on the inner surface of the sleeve 3215. The welding rib 3216 can be connected and fastened to the welding post 3214 by welding process, for example by ultrasonic welding process. Welding can be performed at the top and side wall of the welding rib 3216. In another embodiment, the welding post 3214 can be disposed on the outer cover 3210a of the connecting seat 3210, and the sleeve 3215 can be disposed on the inner cover 3210b of the connecting seat 3210. The welding post 3214 and the sleeve 3215 can be connected and fixed by welding or other means, which will not be described in detail here. The welding structure disclosed herein can reduce the need for high-power ultrasonic welding machines and greatly reduce welding energy consumption.

[0228] Understandably, the welding fixing method between the welding column 3214 and the sleeve 3215 of this disclosure can be replaced by other known fixing methods such as screws, rivets, and fastening.

[0229] According to an embodiment of the present disclosure, the children's rocking chair 30 may further include a standing foot 3260, which is pivotally connected to the rocker arm 3220 to provide an additional support point for the children's rocking chair 30. When the children's rocking chair 30 does not need to rock, the standing foot 3260 can be unfolded and supported on the support surface. Figures 44A-44B This is a side view of a children's rocking chair 30 according to an embodiment of the present disclosure, wherein the standing feet 3260 are in the folded position and the unfolded position, respectively.

[0230] like Figure 44A As shown, the standing foot 3260 is in the retracted position within the rocker arm 3220. The overall outline of the standing foot 3260 can be flush with or slightly recessed into the bottom surface of the rocker arm 3220, thus being invisible when viewed from the side. At this time, the rocker arm 3220 can swing back and forth on a horizontal plane, thereby causing the child rocking chair 30 to swing back and forth. Figure 44B As shown, the standing foot 3260 is in the extended position, with one end of the standing foot 3260 abutting against the rocker arm 3220 and the other end abutting against the horizontal surface, thereby fixing the child rocking chair 30.

[0231] Figure 45A , 45B 45C is a side sectional view of a child rocking chair 30 according to an embodiment of the present disclosure, wherein the standing feet 3260 are in the folded position, the transition position and the unfolded position respectively. Figure 46 This is a partial exploded view of the standing foot 3260 of a children's rocking chair 30 according to an embodiment of the present disclosure.

[0232] like Figure 45A-45C As shown, the standing foot 3260 can be provided with a handle groove 3261 and a cam groove 3262. The handle groove 3261 opens towards the surface of the standing foot 3260 away from the rocker arm 3220. The handle groove 3261 can be located near the support end 3263 of the standing foot 3260, making it convenient for the user to operate the standing foot 3260 for storage or unfolding. The shape of the handle groove 3261 can be set to resemble the shape of a finger, such as... Figure 45A-45C As shown, the handle groove 3261 is an inwardly inclined recess, making it easier for the operator's fingers to apply force to the handle groove 3261. Optionally, two handle grooves 3261 may be provided on the standing foot 3260, but this disclosure is not limited thereto. The cam groove 3262 may be shaped like a cam, such as... Figure 45A-45CAs shown, the cam groove 3262 can be approximately semi-circular in shape. The cam groove 3262 includes an arc-shaped wall portion 32621 and a flat wall portion 32622. The cam groove 3262 can be located near the abutting end 3264 of the rocker arm 3220 near the standing foot 3260. A mounting groove 3221 can be provided on the rocker arm 3220. In one embodiment, a fixing seat 3280 can also be provided within the mounting groove 3221. The fixing seat 3280 can be fixedly connected to the mounting groove 3221 by riveting or screws, and the standing foot 3260 can be stored in the storage groove 3281 of the fixing seat 3280. Because of the fixing seat, wear on the rocker arm 3220 can be avoided due to the need for the standing foot 3260 to pivot between the extended and retracted positions, thus improving the durability of the rocker arm 3220. In embodiments not shown in other figures, the fixing base 3280 can be omitted, and the standing foot 3260 can be directly stored in the mounting slot 3221.

[0233] In one embodiment, the fixed base 3280 may be provided with a pivot slot 3282, and the pivot shaft 3270 passes through the pivot slot 3282 and the cam groove 3262 on the standing foot 3260, thereby pivotally connecting the standing foot 3260 and the fixed base 3280, so that the standing foot 3260 can rotate around the pivot shaft 3270 along the inner contour of the cam groove 3262.

[0234] exist Figure 45A In the middle position, the standing foot 3260 is in the retracted position, at which time the standing foot 3260 is kept stationary with the fixed base 3280 by friction. The user needs to apply an appropriate force to pull the standing foot 3260, and the abutting end 3264 of the standing foot 3260 can slide along the bottom and side surfaces of the storage groove 3281 of the fixed base 3280. Simultaneously, the pivot shaft 3270 rotates relative to the cam groove 3262 (e.g., ...). Figure 45B (As shown). Further pull the standing foot 3260 until one end of the standing foot 3260 abuts against the fixed base 3280 and the other end abuts against the horizontal surface. At this time, the standing foot 3260 is in the extended position (as shown). Figure 45C (As shown). That is, by pulling the handle groove 3261 backward, the standing foot 3260 can switch between the folded position, the transition position, and the extended position. Conversely, by pushing the handle groove 3261 forward, the standing foot 3260 can switch between the extended position, the transition position, and the folded position, which will not be described in detail here. During the switching of the standing foot 3260 between the extended position, the transition position, and the folded position, the pivot shaft 3270 will move around the arc-shaped edge of the cam groove 3262. In this embodiment, there are two standing feet 3260, each set on a corresponding rocker arm 3220. In other embodiments, there may be only one standing foot 3260, and this disclosure is not limited to this.

[0235] Continue to refer to Figures 45A-45CThe end face of the support end 3263 of the standing foot 3260 is an inclined surface. That is, when the standing foot 3260 is folded into the storage groove 3281 of the fixed base 3280, the end face of the support end 3263 is inclined relative to the circumferential wall of the storage groove 3281. When the standing foot 3260 is in the unfolded state, the end face of the support end 3263 can be parallel to the support surface of the children's rocking chair 30, so that the standing foot 3260 can stand more stably on the support surface, thereby providing more stable support for the children's rocking chair 30.

[0236] The end face of the abutting end 3264 of the standing foot 3260 is a flat surface. That is, when the standing foot 3260 is folded into the storage groove 3281 of the fixed base 3280, the end face of the abutting end 3264 of the standing foot 3260 is parallel to the circumferential wall of the storage groove 3281. This helps the standing foot 3260 to fit well with the circumferential wall of the storage groove 3281. In addition, the length of the bottom surface of the handle groove 3261 of the standing foot 3260 is equal to or slightly greater than the length of the storage groove 3281, so that the standing foot 3260 in the folded state can closely abut against the circumferential side wall of the storage groove 3281.

[0237] Optionally, a transition portion 3265 is provided on one side of the abutment end 3264 of the standing foot 3260, and the transition portion 3265 is rounded. Since the end face of the abutment end 3264 is flat, the provision of the transition portion 3265 allows the standing foot 3260 to switch more smoothly between the folded and unfolded positions around the pivot axis.

[0238] In one embodiment, an anti-slip strip 3290 (e.g., ...) can be provided on the bottom surface of the rocker arm 3220 of the child rocking chair 30. Figure 47 As shown), this increases the friction between the child rocking chair 30 and the supporting surface (ground).

[0239] Alternatively or additionally, an elastic rubber paint can be applied to the bottom surface of the rocker arm 3220 of the children's rocking chair 30, or an elastic rubber pad can be attached, or other similar methods can be used to increase the friction between the children's rocking chair 30 and the ground. Taking the elastic rubber paint as an example, it can contain components with rubber-like properties, such as elastic paint, feel paint, leather paint, rubber paint, plush paint, rubber oil, etc. The thickness of the elastic rubber paint is approximately 0.3mm, which will not affect the appearance of the children's rocking chair 30, and the process of applying the elastic rubber paint is simple, saving manufacturing costs. Before applying the elastic rubber paint to the bottom surface of the rocker arm 3220 of the children's rocking chair 30, only a simple cleaning of the rocker arm 3220 is required, without needing to apply ordinary paint to the bottom surface of the rocker arm 3220, further reducing processing steps and saving manufacturing costs.

[0240] Optionally, when the rocker arm 3220 of the child rocker chair 30 is equipped with a standing foot 3260, similar anti-slip strips and / or elastic rubber paint can also be provided on the surfaces of the standing foot 3260 and the support end 3263 to increase the friction between the standing foot 3260 and the support surface, which will not be elaborated here.
