[0010] According to this disclosure, infant swing 10, etc. Figures 1 to 3 As shown, the swing includes a swing base 12 and a child support 14. The swing base 12 is configured to be placed in a fixed position on a surface, and the child support 14 is configured to hold the child so as to move the child relative to the swing base 12.

[0011] In an exemplary embodiment, the infant swing 10 further includes a child support rocker arm 16, which connects the child support portion 14 to the swing base 12 and is configured to move the child support portion 14 relative to the swing base 12 to soothe a child sitting in the child support portion 14. The child support rocker arm 16 is configured to cause the child support portion 14 to swing left and right relative to the swing base 12, from a lower height center position to a first higher lateral position to the right of the center position, and to a second higher lateral position to the left of the center position.

[0012] The child support rocker arm 16 is configured to raise the child support 14 from a lower height center position and guide it to a first higher lateral position to the right of the center position. Then, the child support rocker arm 16 lowers the child support 14 from the first higher lateral position and guides it back to the lower height center position, and then guides the child support 14 to a second higher lateral position to the opposite left of the center position. The child support rocker arm 16 drives the child support 14 from the second higher lateral position back to the lower height center position, and repeats this cycle. The child support 14 is a first distance D1 from the ground at the lower height center position, and a second distance D2 from the ground at the first higher lateral position and the second higher lateral position. This simulates a gentle rocking motion, thereby soothing the child.

[0013] The child support rocker arm 16 is also configured to improve safety and stability for the child at all times. The child support rocker arm 16 keeps the child support portion 14 aligned parallel to the swing base 12 in all positions, preventing the child support portion 14 from twisting about any axis, thereby safely holding the child throughout the entire left-right swinging motion.

[0014] like Figure 4 and Figure 8 As shown, the swing base 12 includes a first base crossbar 18, a second base crossbar 20, and a U-shaped rear crossbar 22. The first base crossbar 18 engages with the placement surface. The second base crossbar 20 engages with the placement surface and is spaced apart from the first base crossbar 18. The U-shaped rear crossbar 22 connects to the rear ends of the second base crossbar 20 and the first base crossbar 18.

[0015] like Figure 4 and Figure 8As shown, the child support 14 includes a support mounting portion 24, a peripheral crossbar 26, and a child carrier 28. The support mounting portion 24 is configured to mount the child support 14 to the child support rocker arm 16. The peripheral crossbar 26 is connected to the support mounting portion 24 and extends around the child carrier 28. The child carrier 28 is connected to the peripheral crossbar 26 and is formed to include a child receiving space 30.

[0016] like Figure 2 As shown, the child support rocker arm 16 is connected between the first base crossbar 18 and the second base crossbar 20 of the swing base 12 and the support mounting part 24 of the child support part 14. Figures 3 to 9 As shown, the child support rocker arm 16 includes a suspension base 32, a support bridge 34, and a bridge mover 36. The suspension base 32 connects a first base crossbar 18 to a second base crossbar 20. The suspension base 32 is also fixed to the swing base 12 at a position relative to the swing base 12. In some embodiments, the suspension base 32 may be an integral structure. The support bridge 34 is connected to the child support 14 and moves with the child support 14. Further, the support bridge 34 is connected to the support mounting portion 24 and swings with the support mounting portion 24. The bridge mover 36 is configured to guide and drive the support bridge 34 and the child support 14 to perform swinging movements relative to the suspension base 32 and the swing base 12.

[0017] like Figures 3 to 8 As shown, the suspension base 32 includes a base base 38, a first rocker arm column 40, and a second rocker arm column 42. The base base 38 connects the first base crossbar 18 and the second base crossbar 20 of the swing base 12. The base base 38 is connected to the outer casing 91. The first rocker arm column 40 is fixedly connected to the base base 38. The second rocker arm column 42 is also fixedly connected to the base base 38 and spaced apart from the first rocker arm column 40.

[0018] The first rocker arm column 40 and the second rocker arm column 42 extend upward and / or inward from the swing base 12 and the placement surface to provide an elevated mounting surface for the support bridge 34, allowing the support bridge 34 to hang down and / or be suspended, as shown in the figure. The first rocker arm column 40 and the second rocker arm column 42 are positioned on opposite sides of the child support rocker arm 16, thus creating a space between the first rocker arm column 40 and the second rocker arm column 42 for the support bridge 34 and the bridge mover 36. The support bridge 34 extends laterally between the first rocker arm column 40 and the second rocker arm column 42, maintaining the parallel orientation of the child support portion 14. At least a portion of the bridge mover 36 connects the support bridge 34 to the first rocker arm column 40 and the second rocker arm column 42, allowing the support bridge 34 to swing between the first rocker arm column 40 and the second rocker arm column 42.

[0019] As shown in the figure, the first rocker arm column 40 and the second rocker arm column 42 each include a lower end and an upper end. The lower end of the first rocker arm column 40 is connected to the base 38 of the foundation section and is located between the first base crossbar 18 and the second base crossbar 20. The upper end of the first rocker arm column 40 is connected to the bridge mover 36. The second rocker arm column 42 includes a lower end and an upper end. The lower end of the second rocker arm column 42 is connected to the base 38 between the first base crossbar 18 and the second base crossbar 20. The upper end of the second rocker arm column 42 is connected to the bridge mover 36.

[0020] like Figures 6 to 9 As shown, the bridge mover 36 includes a first suspension link 44, a second suspension link 46, and an actuator 48. The first suspension link 44 connects the upper end of the first rocker arm column 40 to the first end 50 of the support bridge 34. The second suspension link 46 connects the upper end of the second rocker arm column 42 to the second end 52 of the support bridge 34 opposite to the first end 50. The actuator 48 is connected to the base 38 and the first suspension link 44. The actuator 48 is configured to drive the support bridge 34 and the child support 14 to swing relative to the swing base 12. In some embodiments, the actuator 48 may be omitted, and the child support 14 may swing relative to the swing base 12 by gravity and / or the force applied thereto by a caregiver.

[0021] The first ends of the first suspension link 44 and the second suspension link 46 are each connected to the corresponding first rocker arm column 40 and the corresponding second rocker arm column 42. The first suspension link 44 and the second suspension link 46 can move relative to the corresponding first rocker arm column 40 and the corresponding second rocker arm column 42 about the upper ends of the corresponding first rocker arm column 40 and the corresponding second rocker arm column 42. The first ends of the first suspension link 44 and the second suspension link 46 are connected to the corresponding first rocker arm column 40 and the corresponding second rocker arm column 42, thereby forming corresponding rotation axes, and the first suspension link 44 and the second suspension link 46 rotate about the corresponding rotation axes.

[0022] The first suspension link 44 and the second suspension link 46 hang down and / or suspend from the upper ends of the corresponding first rocker arm column 40 and second rocker arm column 42, such that the second ends of the first suspension link 44 and the second suspension link 46 are located below their first ends and rotate about the axis of rotation. The second ends of the first suspension link 44 and the second suspension link 46 are connected to the support bridge 34, such that the first suspension link 44 and the second suspension link 46 rotate relative to the support bridge 34. This arrangement allows the support bridge 34 and the child support 14 to maintain a parallel orientation to the swing base 12 while swinging relative to the swing base 12 through the movement of the first suspension link 44 and the second suspension link 46.

[0023] Actuator 48 includes motor 54, drive shaft 56, and crankshaft 58. Motor 54 is fixed to base 38. Drive shaft 56 is configured to rotate about a rotation axis 64 transverse to the swing motion. Actuator 48 drives first suspension link 44 and second suspension link 46 to move, which in turn causes support bridge 34 to translate relative to first rocker arm column 40 and second rocker arm column 42 and swing base 12. In this way, actuator 48 drives bridge mover 36, support bridge 34, and child support 14 to move.

[0024] The crankshaft 58 includes a first end 60 and a second end 62. For example... Figure 9 As shown, the first end 60 is eccentrically connected to the drive shaft 56 relative to the rotation axis 64. The second end 62, opposite to the first end 60, is connected to the first suspension link 44, such that when the motor 54 drives the drive shaft 56 to rotate around the rotation axis 64, it drives the first suspension link 44, the support bridge 34, and the child support 14 to perform a swinging motion. When the drive shaft 56 rotates around the rotation axis 64, the first end 60 rotates around the rotation axis 64.

[0025] like Figure 9 As shown, actuator 48 may further include a drive belt assembly 66 and a gearbox 68. The drive belt assembly 66 is coupled to motor 54. The gearbox 68 is coupled to drive belt assembly 66 and drive shaft 56 to transmit motion of motor 54 to drive shaft 56 via drive belt assembly 66 and gearbox 68.

[0026] like Figure 9 As shown, the drive belt assembly 66 includes a drive pulley 70, a driven pulley 72, and a drive belt 74. The drive pulley 70 is connected to a motor 54. The driven pulley 72 is connected to a gearbox 68. The drive belt 74 surrounds the drive pulley 70 and the driven pulley 72. The motor 54 drives the drive pulley 70, which in turn drives the drive belt 74 to rotate. The drive belt 74 drives the driven pulley 72, which in turn drives the gearbox 68.

[0027] The gearbox 68 converts the rotational input of the driven wheel 72 into the rotation of the drive shaft 56. The gearbox 68 may include one or more gears to change the plane of rotation and / or reduce the rotational speed transmitted from the driven wheel 72 to the drive shaft 56. The drive shaft 56 is coupled to a first end of a crankshaft 58 such that the crankshaft 58 rotates about an axis relative to the drive shaft 56. A second end of the crankshaft 58, opposite the first end, is coupled to at least one of a first suspension link 44 and a second suspension link 46 such that the crankshaft 58 rotates about an axis relative to the first suspension link 44 and the second suspension link 46.

[0028] The rotation of the crankshaft 58 drives the drive shaft 56 to move, which in turn drives the first suspension link 44, the second suspension link 46, and the support bridge 34 to swing between a lower height center position, a first higher lateral position to the right of the center position, and a second higher lateral position to the left of the center position, while the child support 14 remains parallel to the swing base 12. In some embodiments, the output of the motor 54 is directly connected to the crankshaft 58, eliminating the need for the drive belt assembly 66, the gearbox 68, and / or the drive shaft 56.

[0029] The supporting bridge 34 includes a bridge base 76 and a bridge support 78. The bridge base 76 is connected to the bridge mover 36. The bridge support 78 extends upward from approximately the center of the bridge base 76 to engage with the support mounting portion 24 of the child support portion 14. The center of the bridge base 76 is arched to increase the vertical distance between the suspension base 32 and the bridge base 76. At least a portion of the bridge mover 36 is fixedly connected to the suspension base 32 and is located vertically between portions of the bridge base 76 and the suspension base 32.

[0030] The suspension base 32 includes a base base 38, a first rocker arm column 40, and a second rocker arm column 42.

The second rocker arm column 42 is spaced apart from the first rocker arm column 40 and connected to the bridge mover 36. The bridge mover 36 includes an actuator 48. The actuator 48 is fixed to the base base 38 and is located between the first rocker arm column 40 and the second rocker arm column 42 in the lateral direction, and between the bridge base 76 and the base base 38 in the vertical direction.

[0031] In some exemplary embodiments, the child support rocker arm 16 is disposed entirely below the child support portion 14. The child support rocker arm 16 is configured to support the child support portion 14, allowing the child support portion 14 to swing relative to the swing base 12, from a lower height center position to a first higher lateral position to the right of the center position, and to a second higher lateral position to the left of the center position, while the child support portion 14 always maintains an orientation parallel to the swing base 12.

[0032] In some embodiments, the first rocker arm column 40 is connected to the base 38 and the bridge mover 36. The second rocker arm column 42 is spaced apart from the first rocker arm column 40 and is connected to the base 38 and the bridge mover 36. In some embodiments, the actuator 48 is connected to the suspension base 32 and to at least one of the first suspension link 44, the second suspension link 46, and the support bridge 34.

[0033] In some exemplary embodiments, the child support rocker arm 16 includes a suspension base 32, a first suspension link 44, a second suspension link 46, and a support bridge 34. The suspension base 32 is connected to the swing base 12. The first suspension link 44 is connected to the suspension base 32. The second suspension link 46 is connected to the suspension base 32 and is spaced apart from the first suspension link 44 in the lateral direction.

[0034] In some exemplary embodiments, the support bridge 34 includes a first end 50, a second end 52, and a bridge support 78. The first end 50 is connected to a first suspension link 44. The second end 52 is connected to a second suspension link 46. The bridge support 78 is connected to the child support portion 14 and is located in the lateral direction between the first end 50 and the second end 52.

[0035] In some exemplary embodiments, the center of the support bridge 34 is vaulted. This vaulted design increases the vertical distance between the suspension base 32 and the support bridge 34. The child support rocker arm 16 also includes an actuator 48 connected to the suspension base 32 and located laterally between the first suspension link 44 and the second suspension link 46, and at least partially below the support bridge 34.

[0036] In some exemplary embodiments, the suspension base 32 includes a base base 38, a first rocker arm column 40, and a second rocker arm column 42. The base base 38 is disposed below the support bridge 34 and connected to the bridge mover 36. The first rocker arm column 40 is connected to a first suspension link 44. The second rocker arm column 42 is spaced apart from the first rocker arm column 40 and connected to the second suspension link 46. An actuator 48 is fixed to the base base 38 and is located in the lateral direction between the first rocker arm column 40 and the second rocker arm column 42.

[0037] In some exemplary embodiments, the child support rocker arm 16 also includes a rocker arm lock 80, which is connected to the suspension base 32, such as Figures 10 to 11 As shown. The rocker arm lock 80 includes a locking switch 82, a locking lever 84, and a locking member 86. The locking lever 84 is connected to the locking switch 82 and moves with the locking switch 82. The locking member 86 is connected to the locking lever 84. The rocker arm lock 80 can be switched between a locked configuration and an unlocked configuration. In the locked configuration, the locking member 86 engages with the support bridge 34 to prevent the child support 14 from moving relative to the swing base 12. In the unlocked configuration, the locking member 86 retracts from the support bridge 34, releasing the restriction on the child support 14 and allowing the child support 14 to move relative to the swing base 12.

[0038] The rocker arm lock 80 is configured to lock or unlock the child support 14 to allow the child support rocker arm 16 to swing or rock relative to the swing base 12. In some exemplary embodiments, the locking switch 82 is configured to be movable by a user pivoting the locking lever 84 downward. The locking lever 84 is configured to pivot about a locking axis 87. The locking lever 84 is also shaped to form a chamfer 85 for guiding and pulling the locking member 86 out of a locking groove 88 formed in the support bridge 34. When the rocker arm lock 80 is in the locked configuration, the locking switch 82 cuts off power to the actuator 48 to prevent the actuator 48 from operating when the child support 14 is locked. When the rocker arm lock 80 is in the unlocked configuration, the locking switch 82 supplies power to the actuator 48 to allow the actuator 48 to operate normally when the child support 14 is unlocked.

[0039] The child support rocker arm 16 also includes a housing assembly 98, which includes a housing 91 and a support slider 95. The support slider 95 is configured to receive the bridge support 78.

The U-shaped upper crossbar 96 is connected to the rear ends of the second upper crossbar 94 and the first upper crossbar 92.

[0043] According to another embodiment 210 of the infant swing disclosed herein, Figures 12 to 13 As shown. Infant swing 210 and Figures 1 to 11 The child support rocker arm 16 shown and described above is similar. Therefore, the same reference numerals in the 200 series indicate the same features between the infant swing 10 and the infant swing 210. The relevant description of the infant swing 10 is applicable to the infant swing 210 by reference unless it conflicts with the specific description and drawings of the infant swing 210.

[0044] In another alternative embodiment, the infant swing 210 according to this disclosure is as follows: Figures 12 to 13 As shown, it includes a swing base 220, a child support 230, and a child support rocker arm 240. Figure 12 and Figure 13 As shown, the swing base 220 is configured to be placed in a fixed position on the lower surface 212. The child support 230 is configured to hold the child and allow movement relative to the swing base 220. The child support rocker arm 240 is configured to move the child support 230 in a swinging motion relative to the swing base 220, swinging from a lower height center position to a first higher lateral position to the right of the center position, and swinging to a second higher lateral position to the left of the center position. The child support 230 remains parallel to the swing base 220 in all positions, preventing the child support from twisting about any axis.

[0045] In an exemplary implementation, such as Figure 12 and Figure 13As shown, the child support rocker arm 240 is disposed within the outer contour of the swing base 220 and located below the child support portion 230. The child support rocker arm 240 connects the child support portion 230 to the swing base 220, allowing the child support portion 230 to swing relative to the swing base 220 along an arc-shaped trajectory. The child support rocker arm 240 drives and guides the child support portion 230 to swing from a lower height center position to a first higher lateral position to the right of the center position. Then, the child support rocker arm 240 drives and guides the child support portion 230 from the first higher lateral position back to the lower height center position, then guides the child support portion 230 to a second higher lateral position to the left of the center position, and then brings the child support portion 230 back from the second higher lateral position to the lower height center position, and repeats this cycle.

[0046] like Figure 12 and Figure 13 As shown, the child support rocker arm 240 includes a suspension mounting portion, which may be an integral structure or may include a first rocker arm column 242 and a second rocker arm column 244. The first rocker arm column 242 is connected to the swing base 220, and the second rocker arm column 244 is connected to the swing base 220 and spaced apart from the first rocker arm column 242 in the lateral direction. The child support rocker arm 240 also includes a support bridge 246 and a bridge mover 250.
