Implementation Method

[0014] Although the present invention has been illustrated and described herein with reference to specific embodiments, the invention should not be limited to the details shown. Rather, various modifications to these details may be made within the scope of equivalents of the claims and without departing from the invention.

[0015] The directional descriptions such as "front," "back," "up," and "down" used herein are for ease of understanding only. The present invention is not limited to these directions but can be adjusted according to actual circumstances. Although the present invention has been described with reference to exemplary embodiments, the terminology used is illustrative and exemplary, and not restrictive.

[0016] Figure 1 shows a rear perspective view of a seat 1 according to the present invention. The seat 1 is designed to soothe or assist an infant to sleep. According to the present invention, the seat 1 includes: a base 40 for enabling the seat 1 to sit more stably on the ground; a carrier 10 located above the base 40 for supporting an infant; a support 30 extending upward from the base 40 for connecting to the carrier 10 and suspending the carrier 10 above the base 40; and a rocker arm 20, one end of which is rotatably connected to the carrier 10 and the other end of which is pivotally connected to the support 30, such that the carrier 10 can rotate relative to the rocker arm 20 and rock relative to the support 30. For example, rocking relative to the support 30 on the left and right sides. The base 40 and the support 30 of the seat 1 can be integrally or separately arranged. According to this embodiment, the base 40 is arranged as a rod that forms an enclosed space. In other embodiments, the base 40 may also be formed from a continuous plate surface. When the carrier 10 is stationary relative to the base 40, the central area of ​​the carrier 10 is approximately directly above the base 40 and its enclosed space, providing stable support for the carrier 10 and preventing it from tipping over. The support 30 extends upward from the rear edge of the base 40, and wheels 50 are provided at the lower rear end of the support 30. When the seat 1 is placed on a horizontal surface as shown in Figure 1, the wheels 50 will not contact the ground. When changing the location of use, the seat 1 can be tilted backward, causing the wheels 50 to contact the ground and roll, thus facilitating transport. According to this embodiment, two wheels 50 are provided, located on opposite sides of the support 30. Alternatively, the wheels 50 can also be provided on the base 40.

[0017] According to the present invention, to facilitate infant seating and to position the infant in different rocking directions, the carrier 10 of the seat 1 is configured to rotate relative to the base 40, the support 30, and the rocker arm 20. According to the present invention, the carrier 10 includes: a connecting seat 11 for connecting to the rocker arm 20; and a base frame 12 connected to the connecting seat 11. The base frame 12 is frame-shaped. Specifically, the connecting seat 11 is connected to two opposite sides of the base frame 12, for example, the base frame 12 is formed in a generally rectangular frame shape, and the connecting seat 11 is connected to the two longer opposite sides of the base frame 12. Furthermore, the base frame 12 can be directly supported on the ground after the carrier 10 is removed from the rocker arm 20. The base frame 12 can be configured as an arc shape with raised sides (see Figure 2), thus advantageously serving as an independent cradle on the ground. The carrier 10 also includes an armrest frame 15, located above the base frame 12, also frame-shaped, which can be used to secure the upper edge of the seat fabric supporting the infant. The carrier 10 also includes two spaced-apart connecting frames 13, which connect the base frame 12 and the armrest frame 15 respectively. The two connecting frames 13 are also connected to connecting seats 11. For example, the two connecting portions of the two connecting frames 13 that connect to the base frame 12 are also connected to both ends of the connecting seats 11. The carrier 10 also includes a support rod 17 located between the armrest frame 15 and the base frame 12, with both ends connected to the two connecting frames 13 in a U-shape. For example, both ends of the support rod 17 connect to the two connecting points of the two connecting frames 13 and the armrest frame 15. The end of the support rod 17 connected to the connecting frame 13 is higher than the rest of the support rod 17. The end of the support rod 17 facing the armrest frame 15 protrudes forward but does not extend beyond that end of the armrest frame 15. The support rod 17 is used to extend downward between the two ends of the armrest frame 15 to support the bottom of the lining supporting the infant. The vehicle 10 also includes a carrying frame 14, which is connected to the handrail 15 and located above the handrail 15. The two ends of the carrying frame 14 are connected to the two connection points of the handrail 15, which correspond to the two connection points of the handrail 15 and the two connecting frames 13. The user can use the carrying frame 14 to carry the vehicle 10.

[0018] According to the present invention, a carrier mounting portion 100 is provided at the end of the seat 1 where the rocker arm 20 is connected to the connecting seat 11. The carrier mounting portion 100 has a rotating seat 110 and a fixed seat 120, which can rotate relative to each other about an axis X. The fixed seat 120 is fixedly connected to the rocker arm 20, and the rotating seat 110 is detachably connected to the carrier 10. The rotating seat 110 cannot rotate relative to the carrier 10, so that the orientation of the carrier 10 relative to the rocker arm 20 can be adjusted by rotating the rotating seat 110 relative to the fixed seat 120. Specifically, the connecting seat 11 is detachably connected to the rotating seat 110 of the carrier mounting portion 100. For example, the connecting seat 11 can be sleeved on the rotating seat 110 from top to bottom. The specific embodiments of the rotating seat 110 are explained in detail with reference to the following drawings.

[0019] Figure 2 shows a side view of the seat 1 according to the present invention. Figure 2 shows that the fixed seat 120 of the carrier mounting part 100 is fixedly connected to one end of the rocker arm 20, while the rotating seat 110 of the carrier mounting part 100 is connected to the connecting seat 11 of the carrier 10. The connecting seat 11 is connected to the base frame 12 and the connecting frame 13, and the connecting frame 13 is connected to the support rod 17, the armrest 15, and the carrying handle 14, so that the weight of the carrier 10 and the infant is substantially stably supported by the rocker arm 20 through the carrier mounting part 100. Furthermore, the carrier mounting part 100 is located directly above the enclosed space of the base 40 in the vertical direction, making the seat 1 less prone to tipping over. The side view of the base frame 12 is arc-shaped, with the lowest part of the arc located in the middle of the base frame 12 and vertically opposite the connecting seat 11. When the carrier 10 is supported on the ground, the lowest part of the arc touches the ground. If an external force is applied to the carrier 10 at this time, the carrier 10 can sway around the lowest point of the arc to soothe the baby or help the baby fall asleep. The rocker arm 20 is designed to be approximately L-shaped, and the other end of the rocker arm 20 can be pivotally connected to the upper part of the support 30. According to this embodiment, the rocker arm 20 is provided with a pivot part 31 for pivoting with the support 30. The pivot part 31 can pivot relative to the support 30 in a direction perpendicular to the plane of the paper, as shown in FIG. 2. The remaining part of the rocker arm 20 is inserted into the pivot part 31 from the lower side and is fixedly connected to the pivot part 31 by a connector 32, such as a bolt or pin, so that it can sway relative to the support 30 together with the pivot part 31.

[0020] As can also be seen from Figure 2, the wheels 50 do not contact the ground when the seat 1 is laid flat on the ground, thus effectively preventing the seat 1 from being moved unintentionally. The wheels 50 can only slide on the ground when the seat 1 is tilted backward.

[0021] FIG3 shows a bottom cross-sectional view of the seat 1 according to the present invention, cut along section line AA in FIG2. As can be seen from FIG3, the carrier mounting part 100 is located at the center of the base frame 12 and armrest frame 15 of the carrier 10, and the fixing seat 120 of the carrier mounting part 100 is located at the center of the connecting seat 11, which can be molded from a rigid material such as plastic.

[0022] Figures 4, 5, 6, and 7 show front perspective views of the carrier 10 of the seat 1 according to the present invention at different angles. The position of the infant's feet, supported by the support rod 17, is determined based on the position of the support rod 17. After the infant sits in the carrier 10, as seen in Figure 4, the infant's face faces forward; as seen in Figure 5, the infant's face faces backward; as seen in Figure 6, the infant's face faces to the left; and as seen in Figure 7, the infant's face faces to the right. According to the present invention, the rotation of the carrier 10 relative to the rocker arm 20, the support 30, and the base 40 is achieved by rotating the rotating seat 110 relative to the fixed seat 120.

[0023] FIG8 shows a perspective view of the carrier 10 according to the present invention. The carrier 10 can be clearly seen in FIG8. According to this embodiment, a connecting groove 16 is provided at the center of the connecting seat 11. The connecting groove 16 is a through hole penetrating the connecting seat 11, and the rotating seat 110 of the carrier mounting part 100 is inserted upward into the connecting groove 16 to connect with the carrier 10. According to this embodiment, the connecting groove 16 is configured to be similar to a cross shape and has four slots, but the present invention is not limited to this embodiment.

[0024] Figure 9 shows a perspective view of the seat 1 according to the present invention after the carrier 10 has been removed. When using the seat 1, the rocker arm 20 can be rocked left and right relative to the support 30 in a manual or electric manner. When using the electric manner, a motor can be provided in the pivot 31 to drive the rocker arm 20 to swing together relative to the support 30.

[0025] As shown in Figure 9, the rotating seat 110 includes a connecting protrusion 111 located in its middle. The connecting protrusion 111 is used to insert into the connecting groove 16 of the connecting seat 11 shown in Figure 8, and is set to a cross shape corresponding to the shape of the connecting groove 16. According to this embodiment, the connecting protrusion 111 is composed of four protrusions spaced upward around the axis X. Advantageously, at least one of the four protrusions can be different in shape from the other protrusions, and at least one of the four slots of the connecting groove 16 is set to correspond to the at least one protrusion, while the other slots are used to mate with the other protrusions. This advantageously allows the rotating seat 111 and the connecting seat 11 of the carrier 10 to be assembled only in a specific direction, thereby avoiding assembly errors. At the same time, since the outer edges of both the connecting protrusion 111 and the connecting groove 16 are non-circular, after the connecting protrusion 111 and the connecting groove 16 are inserted and engaged, the connecting seat 11 cannot rotate relative to the rotating seat 110, that is, the carrier 10 cannot rotate relative to the rotating seat 110, and the two can only rotate together relative to the fixed seat 120.

[0026] FIG10 shows a perspective view of the rocker arm 20 and the carrier mounting portion 100 according to the present invention. The rocker arm 20 may be integrally formed or assembled from multiple parts as shown in FIG10. The upper connecting portion 21 of the rocker arm 20 is tapered relative to the other parts so as to be inserted into the pivot portion 31 shown in FIG9. The connector 32 shown in FIG9 can be inserted into the through hole in the upper connecting portion 21 to fix the pivot portion 31 and the upper connecting portion 21.

[0027] FIG11 shows a top view and a cross-sectional view of the rocker arm 20 and the carrier mounting portion 100 according to the present invention. The left view in FIG11 is a top view of FIG10, the right view in FIG11 is a cross-sectional view of the left view of FIG11 after being cut along section line BB, and FIG12 is an enlarged view of part C in FIG11, wherein the rocker arm 20 can be constructed of a hollow tube, thereby saving weight and materials. The outer edge of the carrier mounting base 100 is set as circular, and the connecting protrusion 111 is located at the center of the carrier mounting base 100.

[0028] The internal structure of the vehicle mounting section 100 can be seen in the right view of Figure 11. The lower connecting part 22 of the rocker arm 20 extends from the side of the fixed seat 120 of the vehicle mounting section 100 into the fixed seat 120 in a direction perpendicular to the axis X, and is fixedly connected to the fixed seat 120 together with the reinforcing part 24 of the rocker arm 20. The structure of the reinforcing part 24 is shown in Figure 14. The vehicle mounting section 100 also includes a connecting shaft 23 connecting the fixed seat 120 and the rotating seat 110, and the connecting shaft 23 extends along the axis X. The connecting shaft 23 is, for example, a rivet, bolt, etc.

[0029] The details of part C in Figure 11 can be seen more clearly in Figure 12. The connecting shaft 23 is inserted into the fixing part 118 of the rotating seat 110 from above. The head of the connecting shaft 23 is snapped into the boss in the fixing part 118 of the rotating seat 110. The other end of the connecting shaft 23 passes through the through hole in the fixing part 118 and the lower connecting part 22 of the rotating seat 110 and extends to the bottom of the fixing seat 120, so that the rotating seat 110 can rotate relative to the fixing seat 120 around the axis X. The rotating seat 110 is provided with spaced sidewalls 112 and 115 in a radial direction perpendicular to the axis X. The sidewalls 112 and 115 extend circumferentially around the axis X. According to this embodiment, along a radial direction perpendicular to axis X, the rotating seat 110 is provided with an outer sidewall 112 and an inner sidewall 115 spaced apart. The outer sidewall 112 and the inner sidewall 115 are each provided in two layers, that is, there are two outer sidewalls 112 and two inner sidewalls 115, as shown in Figure 13. The positioning part 121 of the fixing seat 120 is located between the outer sidewall 112 and the inner sidewall 115, that is, between the radially inner outer sidewall 112 and the radially outer inner sidewall 115. The positioning part 121 of the fixing seat 120 can abut against the outer sidewall 112 or the inner sidewall 115, or abut against both simultaneously. According to this embodiment, along the extending direction of the lower connecting part 22, the positioning part 121 is opposite to the lower connecting part 22 and has a gap, thereby advantageously allowing the positioning part 121 to partially elastically deform. Alternatively, the positioning part 121 may abut against the lower connecting part 22, that is, against the end of the lower connecting part 22, in which case the positioning part 121 can be provided with greater support.

[0030] According to this embodiment, the reinforcing part 24 of the lower connecting part 22 is, for example, a hollow tube and is provided in two, which are perpendicular to the extension direction of the lower connecting part 22 and are spaced apart from the axis X, so that the connection between the lower connecting part 22 and the fixing seat 120 can be more stable.

[0031] FIG13 shows a bottom view of the rotary seat 110 according to the invention. The rotary seat 110 may be molded from plastic or made by other means. The interior of the connecting protrusion 111 may be molded as a hollow part, thereby advantageously saving material. A fixing part 118 is molded in the center of the hollow part for inserting the connecting shaft 23 shown in FIG11.

[0032] According to this embodiment, the outer side wall 112 is formed around and extends downward along the axis X. The outer side wall 112 is used to abut against the fixed seat 120 in a radial direction perpendicular to the axis X to prevent the rotating seat 110 from moving relative to the fixed seat 120 in a radial direction perpendicular to the axis X, thereby causing the two to misalign in a radial direction perpendicular to the axis X. According to this embodiment, the outer side wall 112 is provided with two layers, one of which is located radially inside the other outer side wall 112, and the outer side wall 112 located on the outside is provided along the outer periphery of the rotating seat 110. The two outer side walls 112 are spaced apart to form a first buffer portion 117A, and at least one first connecting rib 116A is provided between the two outer side walls 112, the first connecting rib 116A connecting the two outer side walls 112. Multiple first connecting ribs 116A are evenly spaced in the circumferential direction around axis X, thereby advantageously strengthening the connection between the two outer sidewalls 112, while reducing material usage compared to a continuous connection between the two outer sidewalls 112. In another embodiment, the rotary seat 110 may have only one outer sidewall 112, which is arranged along the outer periphery of the rotary seat 110.

[0033] According to this embodiment, the inner sidewall 115 is formed around and extends downward along the axis X. The inner sidewall 115 is located inside the outer sidewall 112 and is radially spaced from the outer sidewall 112. According to this embodiment, the inner sidewall 115 is also provided with two layers, one of which is located radially inside the other inner sidewall 115. The inner sidewall 115 located radially inside the other inner sidewall 115 is approximately vertically opposite to the outer periphery of the connecting protrusion 111, so that the rotational force received by the connecting protrusion 111 can be better transmitted to the two inner sidewalls 115. A second buffer portion 117B is also formed between the two inner sidewalls 115, and at least one second connecting rib 116B is also provided between the two inner sidewalls 115. The second connecting rib 116B connects the two inner sidewalls 115. Multiple second connecting ribs 116B are evenly spaced circumferentially around axis X, thereby advantageously strengthening the connection between the two inner sidewalls 115 and reducing material usage compared to a continuous connection between the two inner sidewalls 115. In other embodiments, the rotating seat 110 may have only one inner sidewall 115, which is substantially vertically opposite to the outer periphery of the connecting protrusion 111 or located radially outside the outer periphery of the connecting protrusion 111.

[0034] According to the present invention, at least two, more preferably four, snap-fit ​​portions 113 are provided on the radially outer inner wall 115 of the double inner wall 115. The four snap-fit ​​portions 113 are evenly spaced on the outer inner wall 115. The snap-fit ​​portions 113 are used to cooperate with the positioning portions 121 (see FIG. 14) provided on the fixed seat 120 to position the rotating seat 110 relative to the fixed seat 120 in four different positions, thereby positioning the carrier 10 relative to the rocker arm 20, the bracket 30 and the base 40 in four different positions, as shown in FIG. 4 to FIG. 7. According to this embodiment, the engaging portion 113 is configured as a positioning recess 113. Each positioning recess 113 includes two elastic protrusions 114 extending radially outward from the inner sidewall 115 on the radially outer side, perpendicular to the axis X. Specifically, the elastic protrusions 114 are formed by partially arching outward from the outer sidewall 115, and the edges of the elastic protrusions 114 are rounded. Alternatively, they can be configured in another way. The two elastic protrusions 114 and the radially outer inner sidewall 115 between the two elastic protrusions 114 combine to form the positioning recess 113, which cooperates with the positioning portion 121 (see FIG. 14) provided on the fixing seat 120. For example, the positioning portion 121 is engaged in the positioning recess 113 between the two elastic protrusions 114. According to the present invention, the elastic protrusions 114 may not be provided. Instead, for example, the radially outer inner sidewall 115 may be arched radially inward to form the positioning recess 113 of the present invention. The present invention is not limited thereto. Advantageously, the snap-fit ​​portion 113 is opposite to the second connecting rib 116B in a radial direction perpendicular to the axis X to improve the strength of the positioning recess 113. Specifically, the second connecting rib 116B is opposite to the inner sidewall 115 of the radially outer side between the two elastic protrusions 114 of the corresponding positioning recess 113 in a radial direction to enhance the snap-fit ​​between the positioning recess 113 and the positioning portion 121 on the fixing seat 120.

[0035] In addition, the snap-fit ​​portion 113 may also be provided on the outer wall 112 that is radially inner on the double outer wall 112. Specifically, the snap-fit ​​portion 113 is provided as a positioning recess 113, each positioning recess 113 including two elastic protrusions 114 that are radially inner on the outer wall 112 and protrude inward in a radial direction perpendicular to the axis X.

[0036] Figure 14 shows a top perspective view of the rocker arm 20 and the fixed base 120 according to the present invention. Figure 14 shows the structure of the lower connecting portion 22 of the rocker arm 20. At least one, preferably two or more, reinforcing portions 24 are provided on the lower connecting portion 22. The reinforcing portions 24 are, for example, rods or tubes, and extend laterally through the lower connecting portion 22 in a direction perpendicular to its extension direction. The reinforcing portions 24 are spaced apart from the axis X, specifically located on both sides of the axis X along the extension direction of the lower connecting portion 22. Multiple through holes are provided on the reinforcing portions 24 and the lower connecting portion 22 for fixing the lower connecting portion 22 and the reinforcing portions 24 to the fixed base 120 of the carrier mounting portion 100, thereby increasing the number of fixing points between the rocker arm 20 and the fixed base 120 to achieve a more stable connection. Figure 14 also shows the connecting shaft 23 for connecting the fixed base 120 and the rotating base 110.

[0037] According to the present invention, a positioning part 121 is provided on the fixed base 120 for cooperating with the snap-fit ​​part 113 or positioning recess 113 provided on the rotating base 110 in FIG. 13 in the circumferential direction around the axis X, so as to restrict the rotation of the rotating base 110 relative to the fixed base 120 about the axis X, so that the rotating base 110 and the fixed base 120 are relatively fixed, thereby fixing the carrier 10 and the rocker arm 20 respectively, so as to position the carrier 10. According to the present invention, the positioning part 121 is configured as a positioning protrusion 121, which protrudes upward from the bottom of the fixed base 120. The positioning protrusion 121 can be configured as solid or hollow. As shown in FIG. 14, the positioning protrusion 121 is configured as a hollow elliptical structure with transverse ribs 1221 provided inside to strengthen the strength of the positioning protrusion 121. The positioning protrusion 121 is opposite to the lower connecting part 22 along the extending direction of the lower connecting part 22 of the rocker arm 20, or it can abut against each other, so that the lower connecting part 22 can provide stable support for the positioning protrusion 121. In other embodiments, the positioning protrusions 121 may also be evenly spaced in the circumferential direction around the axis X, but the present invention is not limited thereto.

[0038] FIG15 shows a side view and a cross-sectional view of the rocker arm 20 and the carrier mounting part 100 according to the present invention. The upper view in FIG15 is cut from the section line DD of the lower view, so that a part of the rotating seat 110 and the fixed seat 120 can be seen.

[0039] The positioning protrusion 121, which protrudes upward from the fixed seat 120, is located between the radially inner outer wall 112 of the double outer wall 112 and the radially outer inner wall 115 of the double inner wall 115, and abuts against the outer wall 112 and the inner wall 115. The positioning protrusion 121 is currently located in a positioning recess 113 of the rotating seat 110, and abuts against the elastic protrusions 114 at both ends of the positioning recess 113 in the circumferential direction around the axis X, so as to restrict the rotation of the positioning protrusion 121 relative to the corresponding positioning recess 113. When adjusting the orientation of the carrier 10, the rotating seat 110 rotates relative to the fixed seat 120 due to the user rotating the carrier 10. The elastic protrusion 114 at the rear along the rotation direction deforms radially into the corresponding second buffer portion 117B due to the resistance of the positioning protrusion 110, so that the positioning protrusion 110 disengages from the positioning recess 113. As the rotating seat 110 continues to rotate, for example as shown in Figure 15, after the rotating seat 110 rotates 90°, the positioning protrusion 110 engages with another positioning recess 113 again, thereby changing the orientation of the carrier 10 by 90 degrees and positioning it. In the above manner, the carrier 10 can be positioned in the four orientations shown in Figures 4 to 7 respectively.

[0040] Alternatively, the positioning protrusion 121 can be provided on the rotating seat 110, and the positioning recess 113 can be provided on the fixed seat 120. That is, the snap-fit ​​part 113 is provided as the positioning protrusion 121, the positioning part 121 is provided as the positioning recess 113, and the fixed seat 121 is provided with an inner sidewall 115 or an outer sidewall 112 forming the positioning recess 113.

[0041] Alternatively, at least two, preferably four, positioning protrusions 121 may be provided on the fixed seat 120. The positioning protrusions 121 are spaced apart in the circumferential direction around the axis X, while the rotating seat 110 has only one positioning recess 113, for example. The carrier 10 is positioned at different positions by the cooperation between the positioning recess 113 and different positioning protrusions 121.

[0042] By providing a locking part 113 and a positioning part 121 that cooperate with each other on the fixed seat 120 and the rotating seat 110, such as a positioning protrusion 121 and a positioning recess 131, the rotational positioning of the carrier 10 is realized. The carrier has fewer parts, a simple structure, and is easy to operate.

[0043] Since this application can be implemented in various forms without departing from the spirit and substance of this application, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted in the broadest possible sense within the scope of the claims. Therefore, all variations falling within the scope of the claims or their equivalents should be covered by the scope of the claims. [Simplified Explanation of the Diagram]
