Description

Technical Field

[0001] This application claims priority to U.S. Provisional Patent Application No. 63 / 019,656, filed May 4, 2020; No. 63 / 070,503, filed August 26, 2020; No. 63 / 109,086, filed November 3, 2020; No. 63 / 116,286, filed November 20, 2020; and No. 63 / 137,496, filed January 14, 2021, the disclosures of which are incorporated herein by reference in their entirety.

[0002] This invention relates to a cradle assembly, and more particularly to a cradle assembly containing a bedside cradle assembly, and its specific features and configuration. Prior Technology

[0003] A cradle typically comprises any type of enclosed structure that allows an infant to sleep or rest close to a caregiver. A cradle essentially consists of some form of support structure and an enclosed area, which usually includes some kind of soft support surface for the infant.

[0004] Some known cradles include a static support member, which typically comprises a vertical or upright frame. The support member is usually configured to hold the cradle in a specific position and at a specific height. The cradle is typically fixed to the static support member so that it cannot be easily moved or adjusted without moving the entire cradle assembly. Other known bedside cradles include anchoring elements, such as straps, to specifically secure and fasten the cradle relative to a supporting structure, such as an adjacent bed frame. Therefore, these cradles do not have any ability to rock or otherwise move.

[0005] The effectiveness of a cradle in encouraging infant rest or sleep can be increased by providing some form of regular movement, such as rocking motions, soothing and comforting the infant to promote sleep. The rocking mechanism of the cradle should be simple so as not to disturb or otherwise disrupt a sleeping infant. An intuitive and reliable rocking mechanism is also desirable.

[0006] A further advantage is that the cradle can be removed or detached from the cradle frame or support structure. Therefore, it is desirable to provide a crib assembly that allows caregivers to quickly and easily remove the crib from its support.

[0007] Offering varying degrees of adjustability is also important for cradle components. For example, the ability to adjust the cradle height allows caregivers to position the cradle so that the baby is visible from different situations and positions. This is also important for correctly placing the cradle close to the caregiver's bed, especially given the different heights of mattresses and bed frames. Summary of the Invention

[0008] The present invention typically provides a cradle assembly including various features related to rocking, height adjustment, and the ability to remove the cradle from the rest of the cradle assembly.

[0009] In one embodiment, the present invention provides a rocking mechanism for a cradle assembly configured to allow a cradle to rock in a predetermined pattern to make an infant in it feel comfortable.

[0010] In another embodiment, the invention includes a cradle removably attached to the bottom frame portion or support structure. This feature allows a caregiver to remove the cradle from the main frame and move it to another room or location.

[0011] The cradle assembly disclosed in this invention also includes a height adjustment assembly or mechanism. In one embodiment, a main frame or support structure includes an easily accessible height adjustment actuator.

[0012] In one configuration, the cradle assembly is typically detachable into at least two main parts, thus limiting or minimizing the size of the assembly for transport purposes. Furthermore, the cradle assembly can be quickly and easily assembled without any tools.

[0110] The following description uses certain terms for convenience only and not limitation. The terms "front," "back," "up," and "down" indicate directions of reference in the diagram. The terms "inward" and "outward" refer to directions toward and away from the parts referenced in the diagram. "Axial" refers to the direction along the axis of rotation. Items referenced as "at least one of a, b, or c" (where a, b, and c represent the listed items) refer to any one of items a, b, or c, or a combination thereof. This terminology includes specifically mentioned terms, their variations, and similarly imported terms. []

[0111] The cradle assembly 10 is generally shown in Figure 1A. In one embodiment, the cradle assembly 10 has the capability to provide a soothing rocking motion, as described in more detail herein. In another embodiment, the cradle assembly 10 provides the capability to completely remove the cradle 20 from the frame 40 of the cradle assembly 10. Figure 1A illustrates the cradle assembly 10 in a fully assembled state with the cradle 20 and frame 40. Figure 1B illustrates the frame 40 used to support the cradle 20 when it has been removed. Figure 1C illustrates the cradle 20 removed from the frame 40.

[0112] As shown in Figures 2A and 2B, the cradle 20 can be completely removed from the rest of the cradle assembly 10. In one configuration, this is provided by a cradle support 60, which extends cantileveredly from the frame 40. The cradle support 60 can extend from the frame 40 at an upward angle in the unloaded state where the cradle 20 is detached.

[0113] Those skilled in the art will understand that the cradle support 60 can be formed as a frame, arm, or any other type of support structure configured to secure the cradle 20. In one embodiment, the cradle support 60 is formed as a support structure with a dovetail-connected frame 40.

[0114] As shown in more detail in Figure 2C, when the cradle support 60 is in the unloaded state, i.e., when there is no infant in the cradle, the cradle support 60 can be tilted upward at an angle (α) relative to the horizontal plane (PH) at its end region relative to the frame 40. In one embodiment, this angle (α) is between 0 and 3 degrees, preferably 2.5 degrees. In another embodiment, when the cradle 20 is installed and there is no infant in the cradle 20, and when the cradle assembly 10 is in its lowest height position, the angle (α) is selected such that the angle (α) is between 0 and 2.5 degrees, and preferably 1.5 degrees. This configuration essentially solves the deflection of the cradle support 60 due to its cantilever configuration, while still providing a positive angle for the sleeping surface in the cradle 20. In one example, the cradle support 60 is configured to deflect approximately 1.5 degrees when a 20-pound load is placed in the cradle 20. In one embodiment, when fully loaded, the angle (α) is essentially 0 degrees. By presetting the angle (α) of the cradle support 60 to a specific angle before installing the cradle 20, negative angles (drooping) are largely avoided.

[0115] Once the cradle 20 is attached, the cradle support 60 will naturally tilt, sink, or otherwise slightly lower. Furthermore, once an infant is placed in the cradle 20 attached to the cradle support 60, the cradle support 60 will further lower, sink, or otherwise descend. In one embodiment, when the infant is placed in the cradle 20 attached to the cradle support 60, the cradle support 60 is at an angle relative to the frame 40 such that the bottom plane of the cradle 20 and the bottom plane of the cradle support 60 are substantially parallel to the horizontal plane (PH). Those skilled in the art will appreciate that the bottom plane of the cradle 20 being substantially parallel to the horizontal plane (PH) includes slight variations in the angle of the bottom plane of the cradle 20, for example, less than 5 degrees relative to the horizontal plane, more preferably less than 3 degrees, and even more preferably less than 1 degree.

[0116] A fastening interface is provided between the cradle 20 and the cradle support 60, which is described in more detail, at least with respect to Figures 12A to 13E. The cradle 20 is configured to be removably secured and supported by the cradle support 60, and once removed, the cradle 20 is completely independent, as shown in Figure 1C. Thus, the cradle 20 can be used as an infant sleeping area in a location away from the frame 40. As shown in Figures 2A and 2B, the cradle support 60 typically includes an elliptical tubular frame that generally has a profile that matches the perimeter of the bottom of the cradle 20. Those skilled in the art will appreciate that the exact shape and configuration of the cradle support 60 can be varied.

[0117] Figure 3A illustrates another view of the frame 40 and provides further details to illustrate the rocking mechanism 50. In Figure 3A, region 3B is enlarged in Figure 3B to show a view of the rocking mechanism 50, and region 3C is enlarged in Figure 3C to show the rocking mechanism 50 engaged with the cradle support 60.

[0118] Figure 4A illustrates a cross-sectional view of the rocking mechanism 50. As shown in Figure 4A, the rocking mechanism 50 includes a pivot shaft 52 and an attachment member 54. The pivot shaft 52 is connected to the attachment member 54. The attachment member 54 can be frictionally engaged with the pivot shaft 52 through an opening formed in the attachment member 54, the opening being configured to engage around the pivot shaft 52. Those skilled in the art will understand that the pivot shaft 52 and the attachment member 54 can be connected in other ways, or these components can be integrally formed.

[0119] The attachment 54 provides a connection or interface between the pivot 52 and the cradle support 60. As shown in Figures 4B and 4C, the pivot 52 is configured to rotate, causing the attachment 54 to rock or rotate. The motion illustrated in Figures 4B and 4C shows the rocking motion of the cradle support 60. In one configuration, the pivot 52 is freely rotatable. The pivot 52 is configured to rotate about its axis (AS) and provide pivoting motion to the attached cradle support 60. This specification provides additional details regarding the pivot 52 and its rotational capability or the provision of pivoting motion.

[0120] The attachment 54 includes at least one socket 55a, 55b, which is scaled to receive a portion of the cradle support 60. In one embodiment, the attachment 54 includes two sockets 55a, 55b, which are scaled to receive a portion of the cradle support 60. As shown in Figures 4B and 4C, the two sockets 55a, 55b are positioned on opposite sides of the pivot 52 to provide a uniform load on the rocking mechanism. Figures 4D and 4E illustrate top views of the cradle assembly to show the rocking motion associated with Figures 4B and 4C. Figures 4F through 4H further illustrate the cradle 20 in various rocking positions.

[0121] In one configuration, the pivot 52 is positioned in a non-vertical position. This configuration causes the rotational motion of the pivot 52 to mimic the swing motion of a natural pendulum, thus providing a rocking motion for the cradle 20.

[0122] As shown in Figure 4A, the axis (AS) of the pivot 52 can be configured at an angle (θ) of 3 to 10 degrees relative to a vertical axis (AV) extending perpendicularly from the ground or support surface. In a preferred embodiment, the pivot 52 is tilted or configured at 5-8 degrees relative to the vertical axis (AV). In a more preferred embodiment, the pivot 52 is tilted or configured at 7 degrees relative to the vertical axis (AV). Based on this angle (θ), the cradle 20 experiences a rocking, scooping, and pendulum motion when pushed. The angle (θ) of the pivot 52 is chosen such that the cradle 20 swings within a rocking arc, which is shown in more detail in Figures 4I to 4N.

[0123] Figures 4I to 4N illustrate further details of the rocking arc of the cradle support 60 and the cradle 20. Figures 4I to 4K illustrate the cradle support 60 with the cradle 20 mounted. Figures 4L to 4N illustrate the cradle support 60 in its loaded state. As shown in Figure 4I, which corresponds to the leftmost extreme rocking position of the cradle support 60, and as shown in Figure 4K, which corresponds to the rightmost extreme rocking position of the cradle support 60, an angle (φ) is defined between the bottom plane (PB) on the bottom surface of the cradle support 60 and the cradle 20 relative to the horizontal plane (PH). As shown in Figure 4J, the bottom plane (PB) and the horizontal plane (PH) are parallel or coincident with each other.

[0124] The same angle (φ) is provided in Figure 4L, which corresponds to Figure 4I without cradle 20; in Figure 4M, which corresponds to Figure 4J without cradle 20; and in Figure 4N, which corresponds to Figure 4K without cradle 20.

[0125] The angle (φ) of the bottom plane (PB) at the extreme swing positions (i.e., the rightmost and leftmost swing positions) is set within 5 degrees of the horizontal plane (PH) parallel to the ground or support surface. In one configuration, the bottom plane (PB) is preferably kept within 1 to 3 degrees relative to the horizontal plane (PH).

[0126] The rocking mechanism 50 and the pivot shaft 52 may include, but are not required to be, a drive mechanism, such as a motor or at least a spring, to provide the rocking motion of the cradle 20.

[0127] The cradle assembly 10 can be a non-electric assembly, meaning it does not require an external power source. After the user or caregiver applies an initial pulsation or push to the cradle 20, it utilizes gravity and momentum to provide rocking motion. Assuming the infant weighs between 6 and 20 pounds, gently pushing the cradle 20 can provide at least two to three minutes of rocking motion.

[0128] In another specific embodiment, the pivot shaft 52 may be configured entirely vertically and may be provided with other mechanical components to assist the oscillating motion, such as a drive mechanism. In one embodiment, at least one of a magnetic drive system, a DC motor assembly, a gearbox assembly, and / or any one or more combinations thereof may be used to drive the pivot shaft 52. In one embodiment, at least one of a compression spring or a torsion spring may be used to drive the pivot shaft 52. Those skilled in the art will appreciate that in another configuration, the pivot shaft 52 may be stationary and may be provided with other components configured to rotate about the axis of the pivot shaft 52. For example, the pivot shaft 52 may be stationary while the attached component 54 rotates about it.

[0129] As shown in Figure 5A, the cradle support 60 includes rocking attachment portions 62a and 62b. The rocking attachment portions 62a and 62b may include at least one extension, such as a tube or rod, engaged within at least one socket 55a and 55b. In one configuration, a spring-locking assembly 61 may be provided between the rocking attachment portions 62a and 62b and the sockets 55a and 55b. As shown in Figure 5A, the rocking attachment portions 62a and 62b include two cantilever rods or tubes. The connection between the rocking attachment portions 62a and 62b and the sockets 55a and 55b can be achieved by any number of fastening devices, such as friction mating or locking pins or elements. Those skilled in the art will understand that the rocking mechanism 50 may include an extension and the cradle support 60 may include a socket configured to receive the extension in another configuration. Figure 5B illustrates another interface between the rocking attachment portions 62a and 62b and the housing 56. The housing 56 generally defines the connection or interface between the cradle support 60 and the frame 40.

[0130] Figures 6A to 6C illustrate additional configurations of the rocking mechanism 50. As shown in Figure 6A, the rocking mechanism 50 may be formed in a housing 56 that engages with the top of the frame 40. In one configuration, as shown in Figure 6B, housings 56a and 56b may comprise two halves of the housing, namely a front housing and a rear housing. Furthermore, an opening 56c may be defined by housing 56b. Additional details of the rocking mechanism 50 are shown in Figure 6C.

[0131] The rocking mechanism 50 includes a pivot support 57a, 57b, 57c, which may include multiple components such as brackets or supporting housing elements. In one embodiment, the pivot support 57a, 57b, 57c may include a pair of brackets 57a, 57b attached to the frame 40 and the main housing support 57c. A pair of bearings 57d, 57e may be configured at opposite ends of the pivot 52 within the main housing support 57c. Based on these bearings 57d, 57e and other supporting components, the pivot 52 is freely rotatable within the frame 40. As used with respect to the pivot 52, the term "freely rotatable" means that the pivot 52 can rotate or give pivoting motion in an unimpeded manner, particularly when something connected to or attached to the pivot 52 (i.e., the cradle support 60 and the cradle 20) is pushed. Any force, movement, or thrust applied to the cradle support 60 and the cradle 20 is transmitted to the pivot 52 via the attachment member 54. Because the pivot 52 is freely rotatable, the cradle support 60 and the cradle 20 will continue to sway for a period of time after being pushed. In another embodiment, the term "freely rotatable" relative to the pivot 52 means that the pivot 52 can rotate freely within a predetermined range. For example, a rotation stop or end stop can be provided for the pivot 52 to limit rotational or pivoting movement.

[0132] Figure 6D illustrates the rocking angle (β) of the cradle 20. As shown in Figure 6D, the rocking angle (β) is defined as at least 25 degrees between the centerline (CL) and the midline (ML) when the cradle 20 is in its extreme rocking position. Those skilled in the art will understand that the rocking angle (β) is adjustable and can be greater than or less than 25 degrees (i.e., a total of 50 degrees).

[0133] Figure 6E illustrates an enlarged portion of Figure 6D, "6E". As shown in Figure 6E, a pair of stops 156a, 156b may be disposed within the housing 56. In one embodiment, the pair of stops 156a, 156b is defined on a bracket 57a. The pair of stops 156a, 156b may include stop surfaces comprising rubber ends, such as thermoplastic elastomers, which act as buffers for the attachment member 54. Other stop configurations or components may be used.

[0134] Brackets 57a and 57b may be separate from or integrally formed with the main housing bracket 57c. These support components typically secure the rocker mechanism 50 to the frame 40. Components of the pivot brackets 57a, 57b, and 57c may be attached to the frame 40 by any connection method or construction, such as welding, riveting, snap-fitting, press-fitting, or interference fitting, or any other connection or attachment. The pivot brackets 57a, 57b, and 57c, and bearings 57d and 57e, house the pivot shaft 52 and support it in the radial and axial directions. As shown in Figure 6C, the axial end 57f of the reduced-diameter pivot shaft 52 is supported by bearing 57d.

[0135] This invention provides a configuration for locking or preventing rocking motion. A rocking locking assembly 70 is provided, configured to lock the cradle 20 in a stationary position. As shown in Figures 7A to 7C, the rocking locking assembly 70 can be disposed in the front handle portion 64 of the cradle support 60. As shown, the front handle portion 64 is positioned away from the frame 40 or relative to its end. Those skilled in the art will appreciate that the locking feature can also be provided on the frame 40 itself, or on the cradle support 60 in an area adjacent to or close to the frame 40, and in any other location.

[0136] The rocking locking assembly 70 includes a locking handle, actuator, or first rocking locking interface 72 configured for user engagement. The locking handle 72 is illustrated in an inward position relative to the front handle portion 64 shown in FIG. 7B and an outward position relative to the front handle portion 64 shown in FIG. 7C. In one embodiment, the locking handle 72 is configured for both inward and outward actuation. Those skilled in the art will appreciate that the locking handle 72 can include any type of actuator configured for user engagement. The configuration of the locking handle 72 in FIG. 7B corresponds to the locking position for rocking, and the configuration in FIG. 7C corresponds to the rocking position. These positions are interchangeable. Furthermore, alternatives to the locking handle 72 include knobs or other types of interfaces.

[0137] Figure 8A provides another view of the rocking locking assembly 70. As shown in Figure 8A, the locking handle 72 is connected to the latch tube 74. In one configuration, the handle 72 and the latch tube 74 are engaged with each other. In another configuration, the handle 72 and the latch tube 74 are integrally formed with each other. The latch tube 74 is connected to the locking handle 72 at one end and to the rocking mechanism 50 at the proximal end.

[0138] Figures 8B and 8C illustrate enlarged cross-sectional views of the rocker locking assembly 70 shown in Figure 7B. As shown in Figure 8B, the locking handle 72 is in the locked position. The locking handle 72 includes at least one locating rib 73a, 73b. As shown in Figure 8B, at least one locating rib 73a, 73b is disposed on the top surface of the locking handle 72. The front handle portion 64 includes a mating element for engaging the at least one locating rib 73a, 73b. The mating element on the front handle portion 64 may include a biasing or spring finger 65. The spring finger 65 extends cantilevered from the main portion of the front handle portion 64. Those skilled in the art will appreciate that any type of mating configuration can be used to provide an interface between the front handle portion 64 and the locking handle 72.

[0139] Figure 8B illustrates the rocking locking assembly 70 in an inward position corresponding to the locked position, and Figure 8C illustrates the rocking locking assembly 70 in an outward position corresponding to the unlocked or rocking position. In the locked position of Figure 8B, the spring finger 65 engages with the first engagement in the positioning rib 73a, and the locking handle 72 is substantially aligned with the front handle portion 64. In the rocking position of Figure 8C, the second positioning rib 73b is pulled past the spring finger 65, and the locking handle 72 is pulled outward relative to the front handle portion 64. A stop 74a may be provided under the latch tube 74 and may be configured to engage with a portion of the cradle bracket 60 when the handle 72 is pushed inward, as shown in Figure 8B.

[0140] Figure 9A is a partial cross-sectional view showing the interface between the rocker mechanism 50 and the proximal end of the latch tube 74. As shown in Figure 9A, the proximal end of the latch tube 74 includes a plunger spring 75 and a plunger 76. The housing 56b includes a groove 58, which is sized to receive a portion of the plunger 76. As shown in Figure 9A, a first pin 75a is configured as a stop pin at the end of the spring 75, while a second pin 75b is configured as a connecting pin connecting the latch tube 74 to the plunger 76. As shown in Figure 9A, the plunger 76 includes an enlarged head with a tapered profile. Those skilled in the art will appreciate that the exact shape and configuration of the interface between the plunger 76 and the groove 58 can be varied. In one configuration, the plunger 76 and the groove 58 have interfaces with complementary shapes. As shown in Figure 9A, the rocker mechanism 50 is in the inward or locked position. Figure 9B is another view from below of the same configuration as Figure 9A. Figure 9C shows the plunger 76 disengaging from the groove 58, causing the rocking mechanism 50 to be in the rocking position. Figure 9D shows the configuration of Figure 9C as viewed from below.

[0141] When the rocking mechanism 50 is in the inward or locked position, the latch tube 74 is pushed toward the housings 56a and 56b. The plunger 76 is deflected by the plunger spring 75, causing the plunger 76 to engage with the groove 58. The rocking mechanism 50 is held in the locked position by engaging the positioning rib 73a with the spring finger 65 on the front handle portion 64.

[0142] Figures 9E and 9F show enlarged views of the interface between plunger 76 and groove 58. As these figures show, the head of plunger 76 has a tapered or angled profile that typically matches the corresponding tapered or angled profile of groove 58. Based on the interface between plunger 76 and groove 58, when the rocking mechanism 50 is in the locked position, under strong force or impact on cradle 20, plunger 76 will be forced out of groove 58 based on the biasing force of the impact force over the plunger spring 75. Plunger spring 75 provides a damping element that absorbs any impact on cradle 20. Therefore, cradle assembly 10 includes protective components or assemblies, including at least plunger spring 75, plunger 76, groove 58, etc., that protect the mechanical aspects of cradle assembly 10, particularly rocking mechanism 50, from damage in the event of accidental force applied to or impact on cradle assembly 10. This will allow cradle 20 to rotate or rock freely, thereby preventing any damage. Even when the plunger 76 is not aligned with the groove 58, the plunger spring 75 allows the rocking mechanism 50 to be placed in the inward position for locking. When the cradle 20 rotates to the position where the plunger 76 and the groove 58 are rotatably engaged, the tapered end of the plunger 76 is pushed into the groove 58, thereby ensuring that the cradle 20 will be in the locked position.

[0143] Figures 10A to 10C illustrate another configuration of the rocking locking interface or mechanism. Figure 10B corresponds to the unlocked or rocking position, and Figure 10C corresponds to the locked or non-rocking position. As shown in Figures 10B and 10C, the rocking mechanism 50 includes a locking interface 80 exposed from the housing 56. As used herein, the term locking interface refers to a lever, actuator, handle, or other component configured to initiate and release the locking function of the rocking mechanism 50. The locking interface 80 (also referred to as the second rocking locking interface 80) includes a housing having a pivot connection 81 and an engagement rib 82. The engagement rib 82 is configured to engage with corresponding recesses 83a, 83b formed in the housing 56. In this particular embodiment, the rocking locking mechanism is disposed directly on the housing 56, rather than in the end region of the cradle support 60. Those skilled in the art will appreciate that a first rocking locking interface 72 or a second rocking locking interface 80 may be provided to prevent rocking motion.

[0144] The locking interface 80 is pivotally secured to the housing 56 via a pivot connection 81. This configuration allows the locking interface 80 to rotate upward to a rocking position and downward to a locked position. The locking interface 80 is held in these positions by engaging an engagement rib 82 within an upper recess 83a or a lower recess 83b formed on the housing 56.

[0145] When the locking interface 80 is in the upward position, the locking pin housing 84 is biased towards the upward position (i.e., the rocking position). As shown in Figure 10B, this bias configuration is provided by the main spring 85a. In this upward position, the engaging pin 86, partially housed in the locking pin housing 84, is in a generally upward position, as shown in Figure 10B.

[0146] When the lock is actuated, the locking pin housing 84 and the engaging pin 86 are driven downward together, causing the engaging pin 86 to extend within the engaging plate 87a. Specifically, the engaging pin 86 is driven within the engaging hole 87b defined on the engaging plate 87a. This engagement locks the cradle 20 in the rest position.

[0147] An auxiliary spring 85b may be disposed within a spring housing 85c connected to the attachment member 54. As shown in FIG10B, the spring housing 85c protrudes upward from the attachment member 54 and contacts the bottom surface of the locking interface 80. The spring housing 85c may include a generally cylindrical body having a slot or opening in a central region. As shown in FIG10B, an engagement pin 86 may be configured to engage the slot of the spring housing 85c. When the engagement pin 86 and the engagement hole 87b are misaligned or misoriented and the locking interface 80 is pushed downward (i.e., in a rocking position), the auxiliary spring 85b deflects the engagement pin 86 generally downward and abuts against the engagement plate 87a. This configuration ensures that the engagement pin 86 abuts against the engagement plate 87a until the attachment member 54 is rotated to align the engagement pin 86 and the engagement hole 87b. When the engagement pin 86 and the engagement hole 87b are aligned, the auxiliary spring 85b pushes the engagement pin 86 into the engagement hole 87b. As shown in Figures 10B and 10C, the auxiliary spring 85b engages the end surface of the locking pin housing 84 at one end and the end surface of the engaging pin 86 at the second end. The main spring 85a has a first end that engages the inner surface of the attachment member 54 and a second end that engages the locking pin housing 84. In one embodiment, the engaging pin 86 is disposed inside the main spring 85a.

[0148] Figures 12A to 12J illustrate further details of the cradle 20. As shown in Figures 12A and 12B, the cradle 20 can be completely detached, removed, or disassembled from the cradle support 60, and the cradle 20 can be used as a completely independent baby basket device.

[0149] As shown in Figures 12C and 12D, the cradle 20 includes a base 22, which typically defines a sleeping surface on a top or first side. In one embodiment, the base 22 may be an injection-molded plastic part. Based on the invention, those skilled in the art will understand that other materials and forming methods can be used to form the base 22. The cradle 20 also includes at least one housing 24a, 24b and an upper frame 26. As shown in Figure 12C, at least one housing 24a, 24b extends generally vertically between the base 22 and the upper frame 26. At least one housing 24a, 24b has a first end 24c attached to the base 22 and a second end 24d extending away from the base 22 and connected to the upper frame 26. As shown in Figure 12D, the upper frame 26 may include two halves 26a, 26b, or may be formed as a single tube or rod. Enclosed sections, such as those made of soft material or articles, are configured to surround at least a portion of the cradle 20. In addition, the mattress or other form of padding is configured to be mounted on or fixed to the base 22.

[0150] Figure 12F includes an enlarged view of the housing 24a along a portion of plane 12F-12F shown in Figure 12E. As shown in Figure 12F, the housing 24a includes a closed section 25a and an inner cover 25b that are fastened to each other. Those skilled in the art will understand that the housing can also be formed as a single unit. A release actuator 27a is disposed between the closed section 25a and the inner cover 25b. In one configuration, the release actuator 27a is formed as a release handle. As shown in Figure 12F, the release handle 27a is fully recessed into the cradle 20. The release handle 27a is deflected to a downward position by a spring 27c, which typically corresponds to the state in which the cradle 20 is fixed to the cradle support 60.

[0151] Rope 27b is connected to release handle 27a at its proximal end and to latch 29 at its distal end. The term latch, as used herein, refers to any type of release mechanism or element configured to engage with another component. Latch 29 is also referred to herein as an engagement feature.

[0152] In one embodiment, the cord 27b may be pivotally connected to a boss molded with a latch 29. The latch 29 is configured to pivot and is generally biased to engage with the cradle support 60 when the release handle 27a is not pulled. In one embodiment, a spring may be provided to bias the latch 29 to engage with the cradle support 60. Other biasing elements or configurations may be used. As shown in FIG12F, the latch 29 is configured to nest or reside within a cavity 23 defined in the bottom surface of the base 22, which is opposite to the sleeping surface. In one embodiment, the cavity 23 serves as an engagement feature with the cradle support 60. Those skilled in the art will appreciate that other engagement features may be provided. The latch 29 engages the cradle support 60 to prevent the cradle 20 from being lifted from or otherwise removed from the cradle support 60. In one embodiment, the cavity 23 is the first engagement feature and the latch 29 is the second engagement feature configured to engage with the cavity 23. Although the latch and cavity are shown as engaging features in the accompanying drawings, those skilled in the art will understand that other configuration types can be used to secure the cradle to the cradle support.

[0153] Figures 12G and 12H illustrate the disengagement of latch 29 from cradle support 60 while handle 27a is pulled. Figure 12H is an enlarged view of portion "12H" shown in Figure 12G. When handle 27a is pulled upward against the force of spring 27c, latch 29 rotates clockwise about its pivot axis and retracts from its extended position as shown in Figure 12F, thus moving out of cavity 23. When handle 27a is pulled (indicated by arrow (A) in Figure 12H), rope 27b is guided by track 31 molded in housing 24a. The end of rope 27b pulls latch 29, causing it to rotate clockwise, as shown in movement (B) in Figure 12H. This movement of latch 29 disengaging from cradle support 60 and entering housing 24a empties cavity 23 of latch 29, thereby allowing removal of cradle 20 by raising it relative to cradle support 60.

[0154] Figure 12I shows a bottom view of the cradle 20. Figure 12J is an enlarged view of region "12J" in Figure 12I. As shown in Figure 12J, the latch 29 is in a separated position relative to the support tube 12. Depending on whether the handle 27a is pulled up or released, the latch 29 is shown in a fully inwardly rotated position. Slots are defined in the end of the rope 27b and the front surface of the latch 29. These slots allow the latch 29 to rotate independently of the handle 27a, such as when the cradle 20 is mounted on the cradle support 60.

[0155] Figures 13A to 13E illustrate other configurations and features of the cradle 20. Specifically, Figures 13A to 13E illustrate other configurations of the cradle release assembly, similar to the configurations shown in Figures 12A to 12J.

[0156] As shown in Figure 13B, the release handle 127a is biased to a downward position by the spring 27c. The release handle 127a is disposed at a first end of the connector body 127b. The second end of the connector body 127b includes a pivot latch 129. The pivot latch 129 typically engages with the cradle support 60 to ensure that the cradle 20 remains positioned. The cradle support 60 is sized to fit within a cavity 23 defined on the underside of the cradle 20.

[0157] As shown in more detail in Figures 13C and 13D, a cam 127d is disposed on the connector body 127b, and the cam 127d engages a portion of the pivot latch 129. Specifically, the cam 127d may be configured to surround a post or pin 129a formed on the pivot latch 129. In one configuration, the handle 127a, the connector body 127b, and the cam 127d are integrally formed with each other.

[0158] Figure 13E provides a lower view of the cradle 20 and the cradle support 60 to illustrate how the cradle 20 is secured to the cradle support 60.

[0159] Figures 11A to 11D reveal additional features of the cradle assembly 10, including the cradle 20, frame 40, and cradle support 60. The cradle 20 is adjustable to multiple height positions, as shown in Figures 11A and 11B. The frame 40 is shown in a lower position in Figure 11A, with the cradle 20 attached to it. In Figure 11B, the frame 40 is in a raised position without the cradle 20. Figure 11C shows other components of the frame 40. Specifically, the frame 40 includes an upright portion 42 and a base portion 44. In this context, the term "upright" generally means upright to the ground but not necessarily perpendicular to it. Figure 11D illustrates another configuration of the cradle assembly 10, where the frame 40 is in its lowest position. A frame enclosure section 40a, shown in Figure 11D, is configured to enclose the bottom of the frame 40. Figure 11E illustrates another view of the cradle assembly 10, and Figure 11F illustrates the cradle assembly 10 shown in Figure 11E without the cradle 20 or the cradle support 60.

[0160] Figures 14A to 16C illustrate further configurations of the height adjustment feature of the present invention. As shown in Figure 14A, the upright portion 42 of the frame 40 includes at least one upper telescopic tube 42a and at least one lower telescopic tube 42b. As shown, the at least one upper telescopic tube 42a may include two tubes 42a, 42a', and the at least one lower telescopic tube 42b includes two tubes 42b, 42b'. Generally, the upper half of the upright portion 42 within the frame is designated as the upper telescopic portion 43a in Figure 14A, while the lower half is designated as the lower telescopic portion 43b in Figure 14A. The height adjustment feature of the frame 40 typically occurs through telescopic movement between the upper telescopic portion 43a and the lower telescopic portion 43b. This configuration is shown in Figure 14B, which shows a cross-sectional view of the interface between these components. Adjustment movement or motion occurs between the at least one upper telescopic tube 42a and the at least one lower telescopic tube 42b.

[0161] Figures 14C and 14D show additional details regarding the interface between the upper telescopic portion 43a and the lower telescopic portion 43b. Figure 14C is a cross-sectional view of the upper telescopic portion 43a and the lower telescopic portion 43b. This configuration includes a release connector 47, which is connected at one end 47a to the actuator 68, as described in more detail in this specification. The release connector 47 is attached at the other end to a pawl 48, which includes a first end 48a connected to the release connector 47 and a second end 48b defining a protrusion extending through a height adjustment slot 45 in the lower telescopic tube 42b. A spring 51 is attached at one end to the pawl 48 and at the second end to a support structure 49 within the upper telescopic tube 42a.

[0162] Adjustment or movement between the upper telescopic portion 43a and the lower telescopic portion 43b is provided by a pivoting pawl 48 in the upper telescopic tube 42a. The pawl 48 pivots about a pivot pin 48c and is deflected counterclockwise by a spring 51. The deflection of the spring 51 causes the pawl 48 to selectively pass through one of a plurality of slots 45 in the upper telescopic tube 42a. Engagement of the pawl 48 with these slots utilizes the securing of the upper telescopic tube 42a and the lower telescopic tube 42b to fix the height of the frame 40. To adjust the height between the upper telescopic portion 43a and the lower telescopic portion 43b, the pawl 48 is rotated clockwise by engagement with an actuator 68, which disengages the pawl 48 from the slots 45 in the upper telescopic tube 42a. Pulling or actuating the release connector 47 drives the pawl 48 to disengage from the slots 45. As shown in Figures 15A and 15B, the upper telescopic portion 43a is attached to a housing 56 formed on top of the frame 40. Housing 56 includes a height adjustment lock or actuator 68, shown in FIG. 15A as being in a rest or downward position and in FIG. 15B as being in an engaged or upward position. As shown in FIG. 15A and FIG. 15B, the same housing 56 may include a rocking locking interface 80 for controlling the locking and unlocking of the rocking mechanism 50, and a height adjustment actuator 68 for adjusting the height of the cradle assembly.

[0163] Figures 16A to 16C illustrate further details of the latch 68 and its interface with the release connector 47. In one embodiment, the latch 68 may include a crossbar or pin extending through a ring or opening at the end of the release connector 47. As shown in these figures, the release connector 47 provides a connection between the pawl 48 and the latch 68. When the latch 68 is pressed up or engaged, tension is applied to the release connector 47, which is converted into a force acting on the pawl 48, causing the pawl 48 to rotate clockwise and disengage from the slot 45, thereby allowing the cradle 20 to be height adjusted.

[0164] To achieve a relatively small packaging size for transport, frame 40 is assembled to base 44 using connecting elements. As shown in Figure 17A, in one configuration, base 44 is secured to the rest of cradle assembly 10 by supports or tubes 46, 46' arranged on base 44. In another configuration, supports 46, 46' are welded to base 44. Supports 46, 46' are configured to receive lower telescopic tubes 42b, 42b'. Those skilled in the art will understand that, depending on the number of upright support elements or tubes, a single support or two or more supports may be provided.

[0165] As shown in Figures 17B and 17C, fasteners 53a and 53b are provided to mate with nuts 59a and 59b. As shown in Figure 17B, fasteners 53a and 53b extend through the base 44 and into the bearings 46 and 46'. In one embodiment, fasteners 53a and 53b are bolts. Nuts 59a and 59b are typically disposed within the lower telescopic tube 42b. In another embodiment, plates 59c and 59d are fixed within the cavity of the lower telescopic tube 42b. Plates 59c and 59d may be welded or otherwise fixed to the lower telescopic tube 42b. Those skilled in the art will understand that the base 44 may include nuts 59a and 59b, and fasteners 53a and 53b may extend through plates disposed on the lower telescopic tube 42b. To maintain component rigidity and reduce wobbling, the customer installs two bolts 53a and 53b through the base 44 into the nuts 59a and 59b.

[0166] Figures 18A to 21C illustrate other configurations of the cradle assembly 10. As described in more detail in this specification, the frame 40 can be easily assembled to the base 44. The lower portion of the frame 40 may include at least one tube, conduit, bracket, or other structure configured to engage the base 44. The base 44 also includes at least one connector configured to mate with the bottom of the frame 40. The frame 40 includes at least one upper tube 42a, 42a' and at least one lower tube 42b, 42b'. The bottom region of the lower tubes 42b, 42b' may include a biasing locking element or a protrusion 41a. As shown in Figure 19C, the biasing locking element 41a may include a protrusion or pin biased by a spring 41b (such as a compression spring). The protrusion 41a is generally biased radially outward from the lower tubes 42b, 42b'. As shown in Figure 19B, the bottom surface of the lower tubes 42b, 42b' includes a recess or curved surface 41c that adapts to engage the base 44.

[0167] Figures 20A and 20B illustrate another configuration of the base 44. As shown in Figures 20A and 20B, at least one bearing 46, 46' is attached to or formed together with the base 44. Each of the bearings 46, 46' includes a socket 46a, which is typically sized to receive a portion of the lower tubes 42b, 42b'.

[0168] In the upper region of the bearings 46, 46', a protruding guide feature 46b is provided, which includes an enlarged opening sized to receive the protrusion 41a. The lower region of the bearings 46, 46' includes an engagement hole, channel, or opening 46c configured to retain the protrusion 41a. Those skilled in the art will understand that the socket 46a may be formed on the lower tubes 42b, 42b', rather than on the bearings 46, 46'. The socket 46a provides a telescopic structure between the lower tubes 42b, 42b' within the bearings 46, 46'.

[0169] Figures 21A to 21C illustrate the interconnected frame 40 and base 44. As shown in Figure 21C, a protrusion 41a extends outward from the lower tubes 42b, 42b' and passes through a hole 46c in the supports 46, 46'. Once the protrusion 41a extends through the hole 46c, the frame 40 and base 44 are secured to each other. The locking or engaging feature between the frame 40 and base 44 can be provided in various forms, as long as a mating or engaging interface is provided between the two components. For example, a bolt can be used instead of a spring, which can be configured to be extended by the user through the opening to secure the frame 40 to the base 44. In another example, the mating interface can be provided by a cantilever spring finger. Alternatively or additionally, the protrusion 41a and spring 41b can be combined into a single spring and pin assembly.

[0170] During assembly, a protruding guide feature 46b, which may be formed on the lower tubes 42b, 42b' or the bearings 46, 46', provides an inclined surface for engaging the protrusion 41a. When the lower tubes 42b, 42b' engage the bearings 46, 46', the protrusion 41a engages the guide feature 46b, thereby retracting the protrusion 41a. When the lower tubes 42b, 42b' are engaged within or around the bearings 46, 46', the protrusion 41a aligns with the engagement hole 46c, thereby allowing the protrusion 41a to extend into the engagement hole 46c.

[0171] The configuration shown in Figures 21A to 21C allows the user to quickly assemble the cradle base and frame by inserting the lower tubes 42b, 42b' or the supports 46, 46' into another component. The guide feature or inclined surface 46b has a profile that allows for easy and quick pressing down of the protrusion 41a until it aligns with the engagement hole 46c. Once the protrusion 41a extends through the engagement hole 46c, the frame 40 and the base 44 are secured to each other. To detach or remove the base 44 from the frame 40, the user simply pushes the protrusion 41a inward, thus disengaging it from the engagement hole 46c.

[0172] Figures 22A and 22C illustrate further configurations of the cradle 20. As shown in Figures 22A and 22C, the baby support surface 21 (i.e., the sleeping surface) of the cradle 20 has a curved profile. Specifically, the baby support surface 21 has a concave profile when viewed in at least one direction. In one configuration, the baby support surface 21 has a concave profile when viewed in both the transverse (Figure 22C) and longitudinal (Figure 22B) directions. This baby support surface 21 generally helps and encourages the baby within the cradle to remain in the central area of ​​the cradle 20, especially during rocking motions. Furthermore, this curved baby support surface 21 helps to keep the baby's head above the baby's heart during rocking. In other words, the curved baby support surface 21 positions the baby's heart lower than the baby's head (i.e., within the lowermost concave portion of the surface 21), while the baby's head is located at the outer edge of the concave portion of the baby support surface 21.

[0173] Figures 23A to 23J illustrate additional embodiments of the invention. As shown in Figures 23A to 23J, an offset support member 90 provides a connection between the cradle 20 and the frame 40. The offset support member 90 may include a first proximal end 90a attached to an attachment member 54 and a second end 90b attached to the cradle support 60. The offset support member 90 may have an "S"-shaped profile, as shown in Figures 23A and 23B. This offset support member 90 serves as an auxiliary height adjustment feature. In one embodiment, a telescopic tube or rod of the frame 40 (such as those described herein with respect to at least Figures 14A to 16C) provides a primary height adjustment assembly or mechanism, and the offset member 90 provides an auxiliary height adjustment assembly or mechanism independent of the primary height adjustment mechanism. Therefore, this configuration enhances the ability to adjust the height of the cradle 20.

[0174] As shown in Figures 23A, 23C, 23E and 23G, the offset support member 90 has been rotated (i.e., within the socket of the attachment member 54) such that the end of the offset support member 90 is higher than the proximal end of the offset support member 90.

[0175] Figures 23B, 23D, 23F, and 23H illustrate an offset support member 90 that is reversed by 108 degrees (i.e., within the socket of the attachment member 54), such that the end of the offset support member 90 is lower than its proximal end. Therefore, the cradle 20 supported by the cradle support 60 shown in Figures 23B, 23D, 23F, and 23H should be lower than the position of the cradle 20 shown in Figures 23A, 23C, 23E, and 23G. The offset support member 90 may be integrally formed with the cradle support 60, or may be separately connected to or attached to the cradle support 60. In one configuration, the offset support member 90 is selectively positioned at a first position corresponding to a first cradle support height and a second position corresponding to a second cradle support height different from the first cradle support height. In either configuration, the cradle 20 can still be rocked by the rocking mechanism 50. In one state, as shown in Figure 23E, an offset (Z) is defined between the first proximal end 90a attached to the attachment member 54 and the second end 90b connected to the cradle support 60. []

[0176] Figure 23I illustrates offset support members 90 at two overlapping positions 90' and 90" respectively. The offset support member 90 at position 90' corresponds to the lower position, while the offset support member 90 at position 90" corresponds to the higher position. Figure 23J is an enlarged view of region "23J" shown in Figure 23I. As shown in Figure 23J, the offset support member 90 can be formed by a pair of offset support members, which are formed as hollow tubes and connected to the cradle support 60.
