As shown in the figure, the support assembly 210 includes a first side section 201, a second side section 202, and a middle section 203. The middle section 203 is positioned substantially between and integrally formed with the first side section 201 and the second side section 202. The middle section 203 is curved, e.g., downward. The first side section 201 is substantially parallel to the second side section 202 along the length of both side sections. The first side section 301, along its length, may be substantially straight. The second side section 302, along its length, may be substantially straight. In this direction, the middle section 203 does not extend beyond the length of the first side section 201 or the length of the second side section 202. The support assembly 210 has an upper side and an underside. The upper side of the support assembly 210 is formed of the upper side of the first side section 201, that of the second side section 202, and that of the middle section 203. The underside of the support assembly 210 is formed of the underside of the first side section 201, that of the second side section 202, and that of the middle section 203. As illustrated, on the upper side of each of the first side section 201, the second side section 202, and the middle section 203, there are patches 204, 205 and 206 of reusable hook-and-loop fasteners. Any one of the patches 204, 205 and 206 may fasten or bind temporarily with a complimentary patch of the reusable hook-and-loop fastener during the time that they are pressed together. The patch and the complimentary patch may be separated by peeling them apart. It is understood that the support assembly 210 may include more or fewer patches on either one of the first side section 201, the second side section 202, and the middle section 203.
The adjustment assembly includes a first adjustment subassembly and a second adjustment subassembly. The first adjustment subassembly includes a first linker 213 and a second linker 214. The second adjustment subassembly includes a first linker 215 and a second linker 216 (invisible in FIG. 2A). The first adjustment subassembly and the second adjustment subassembly are coupled to the support assembly 210 on the underside of the first side section 201 and the underside of the second side section 202. The first adjustment subassembly and the second adjustment subassembly are configured to cooperate to adjust the positioning of the support assembly 210 relative to another portion of the cradle frame, e.g., the beam connector of the connection assembly (discussed below). The relative positioning of the support assembly 210 includes, e.g., the height of the support assembly 210, the distance, the tilting angle of the support assembly 210, or the like.
The connection assembly includes a first beam 211 (see FIGS. 2B-2D), and a second beam 212, and a beam connector including a shaft sleeve 218 (described below in connection with FIG. 4C). The gear assembly may control, e.g., lock or unlock, the relative positioning of the support assembly 210 of the cradle frame (e.g., the table 100 shown in FIG. 1). Part of the gear assembly, a latch 220, is shown in FIG. 2A. The latch 220 may move in the directions as indicated by 230, between an unlocked position 220A as illustrated in phantom and a locked position 220B. When the latch 220 is in the unlocked position 220A, the gear assembly allows for the movements of the first linkers 213 and 215, the second linkers 214 and 216 of the adjustment assembly, and the first beam 211 and the second beam 212 of the connection assembly; while when the latch 220 is in the locked position 220B, the gear assembly prevents the movements of these parts. As illustrated in FIG. 2A, the first linker 213 and the second linker 214 of the first adjustment subassembly substantially align with each other; likewise, the first linker 215 and the second linker 216 of the second adjustment subassembly substantially align with each other. The second linker 214 of the first adjustment subassembly pivotally connected with the first side section 201 of the support assembly 210 at a protrusion 223. The protrusion 223 may be integrally formed with and on the underside of the first side section 201.

Likewise, the first linker 215 of the second adjustment subassembly includes a slot 215A through which the first linker 215 is rotatably and slidably coupled to the beam connector of the connection assembly. The first linker 215 may rotate around the beam connector and slide along the slot 215A.
As used herein, a first structural component being coupled or connected to/with a second structural component is used interchangeably. Both indicate that the movement of the first structural component and that of the second structural component are coordinated. The specific coordination depends on the specific coupling or connection between the first structural component and the second structural component.
FIG. 2B shows the exemplary cradle frame in a lower position with the beams 211 and 212 of the connection assembly in an unfolded configuration. As illustrated, the beams 211 and 212 are extended for coupling the cradle frame to a structure, e.g., the table 100 shown in FIG. 1. In this lower (or unraised) position, the first linker 213 and the second linker 214 of the first adjustment subassembly substantially align with each other; likewise, the first linker 215 and the second linker 216 of the second adjustment subassembly substantially align with each other. The first beam 211 and the second beam 212 of the connection assembly are substantially parallel to each other. The first beam 211 and the second beam 212 as illustrated are substantially straight. It is understood that in other embodiments, one or both of the first beam 211 and the second beam 212 may be curved.
FIGS. 2C and 2D show the exemplary cradle frame in a higher position with the beams 211 and 212 of the connection assembly in an unfolded configuration. As illustrated, the beams 211 and 212 are extended for coupling the cradle frame to a structure, e.g., the table 100 shown in FIG. 1. In this higher (or raised) position, the first linker 213 and the second linker 214 of the first adjustment subassembly do not align with each other; likewise, the first linker 215 and the second linker 216 of the second adjustment subassembly do not align with each other. The beam connector including the shaft sleeve 218 is located below or underneath the support assembly. FIG. 2C shows that the first linker 213 of the first adjustment subassembly is pivotally connected, at an end 213B of the first linker 213, with the first side section 201.
The cushion 250 shown in FIG. 2D may be put on the upper side of the support assembly 210. The cushion 250 may include one or more complimentary patches of reusable hook-and-loop fasteners that may fasten or bind temporarily with the patches 204, 205, and 206 on the upper side of the first side section 201, the upper side of the second side section 202, the upper side of the middle section 203, respectively, during the time that the one or more complimentary patches on the cushion and the patches on the support assembly 210 are pressed together. The patches and the complimentary patches may be separated by, e.g., peeling them apart.
FIG. 3A and FIG. 3B illustrate perspective views of the exemplary cradle frame and the cushion 250 when there is no force applied to the cushion 250 (FIG. 3A) and when a force F is applied to the cushion 250 (FIG. 3B). In both FIG. 3A and FIG. 3B, the exemplary cradle frame is in a lower position with the beams 211 and 212 of the connection assembly in an unfolded configuration, extended for coupling the cradle frame to a structure, e.g., the table 100 shown in FIG. 1. As shown in FIG. 3A, when there is no force applied to the cushion 250, two arms of the cushion 250 temporarily bind, via the complimentary patches of reusable hook-and-loop fasteners on the two arms of the cushion 250 (invisible in FIG. 3A), to the support assembly 210, via the patches 204 and 205 on the upper side of the first side section 201 and the upper side of the second side section 202, respectively. The middle part of the cushion 250 does not bind to the middle section 203 of the support assembly 210 where the middle section 203 is curved, e.g., downward. As shown in FIG. 3B, when the force F is applied to the cushion 250, the two arms of the cushion 250 that originally bind to the first side section 201 and the second side section 202 of the support assembly 210 (as shown in FIG. 3A) deflect, e.g., upward and inward, and partially separate the binding between the two arms of the cushion 250 and the first side section 201 and the second side section 202 of the support assembly 210. The force F pushes the middle part of the cushion 250 downward such that it binds temporarily, via the complimentary patch of a reusable hook-and-loop fastener on the middle part of the cushion 250 (invisible in FIG. 3B), to the middle section 203 of the support assembly 210, via the patch 206 on the upper side of the middle section 203. The downward curve of the middle section 203 may facilitate the middle part of the cushion 250 to move downward when the force F is applied.

The cradle may be coupled to a structure including, for example, a massage table, a massage chair, or a table/bed or chair for medical or other uses, or the like. The cushion may also be used independently as, for example, a neck pillow, or the like.
FIG. 10A and FIG. 10B show perspective views of the exemplary cushion 1. FIG. 10C shows a perspective view of the underside of the cushion 1. There are three patches 2 of reusable hook-and-loop fasteners. These patches 2 may be complimentary to those on the support assembly 210 or the support assembly 310 of exemplary cradle frames already discussed, if the cushion 1 is intended to be used with any one of those exemplary cradle frames.
FIGS. 11A and 11B show the perspective views of the body 3 of the exemplary cushion 1. The body 3 includes a first arm 20, a second arm 30, and a middle part 40. The middle part 40 has a thickness, a length, and a width. The middle part 40, along the length thereof, is positioned substantially between and integrally formed with the first arm 20 and the second arm 30.
As shown in FIG. 11A, on the upper side of the body 3, the first arm 20, the second arm 30, and the middle part 40 may form a contour for better matching the shape of a subject or a part thereof, e.g., the face or the back of a user's head. The outer edge of the body 3 includes the outer edge of the first arm 20, that of the second arm 30, and that of the middle part 40. Along the outer edge of the body 3, the thickness of the body 3 changes continuously and/or smoothly.

FIG. 13A shows that the contour of the upper side of the cushion 1 matches the shape of the back of the user's head well. FIG. 13B shows that the contour of the upper side of the cushion 1 matches the shape of the user's face (or the shape of the user's cheeks) well.
FIGS. 14A and 14B show the empty space 50 in the middle of the exemplary cushion 1. The empty space 50 may accommodate a subject or a portion thereof. Merely by way of example, the subject is a user. The empty space 20 may accommodate the nose, the mouth, and/or the eyes of the user if the user faces downward such that the user's face contacts the cushion 1. The empty space 50 may accommodate a portion of the back of the user's head, if the user faces upward such that the back of the user's head contacts the cushion 1. If the cushion 1 is used as a neck pillow, the empty space 50 may accommodate the user's neck such that the cushion 1 wraps around the user's neck.
FIGS. 15A and 15B show that the arms of the cushion (or the arms 20 and 30 of the body 3 of the cushion 1) deflect upward and inward as indicated by the two arrows D when a force F is applied to the cushion 1. As shown in FIG. 15B, the deflected cushion 1 cradles the back of the user's head.
In some embodiments, a cushion is provided. The cushion includes a body having an upper side and an underside. The body includes a first arm, a second arm, and a middle part. The middle part, along the length thereof, may be positioned substantially between and integrally formed with the first arm and the second arm. The upper side of the cushion is contoured such that it matches the contact surface of an intended subject, or a part thereof, well. The intended subject may be a person or user, or an object other than a person. The contact surface may be, e.g., a face or the back of the head of a user, or a part thereof. The middle part has a thickness, a length, and a width. The middle part, along the length of the middle part, is positioned substantially between and integrally formed with the first arm and the second arm. The middle part may include an opening on the underside of the body of the cushion. The middle part may include more than one opening on the underside of the body of the cushion. The one or more of openings may facilitate the first arm and the second arm to deflect when a force is applied to the upper side of the body. The one or more openings extend partially through the width of the middle part. The one or more openings extend partially through the thickness of the middle part. The one or more openings extend through the entire width of the middle part. The one or more openings extend through the entire thickness of the middle part. The body may be made of a material such as, for example, foam, rubber, or the like. Merely by way of example, the body 3 may be made of memory foam, e.g., polyurethane foam. The cushion may include an empty space in the middle such that the empty space may accommodate a subject or a portion thereof. The cushion may include a cover. The cover may be made of at least one material selected from cloth, paper, plastic, leather, polyester, or the like. The cover may be disposable or reusable.
In some embodiments, a cushion is used in connection with a cradle frame to form a cradle. The support assembly of the cradle frame may include one or more patches of reusable hook-and-loop fasteners on the side sections and/or the middle section of the support assembly. The cushion may include one or more complimentary patches of reusable hook-and-loop fasteners on the two arms and/or the middle part. When there is no force applied to the cushion, two arms of the cushion may temporarily bind, via the complimentary patches of reusable hook-and-loop fasteners on the two arms of the cushion, to the support assembly, via the patches on the upper side of the first side section and the upper side of the second side section, respectively. In some embodiments, the middle part of the cushion does not bind to the middle section of the support assembly where the middle section is curved, e.g., downward. When a force is applied to the cushion (e.g., when a user rests his/her head on the cushion of the cradle, and/or when another person, e.g., a masseur, applies a force to the user who rests his/her head on the cradle), the two arms of the cushion that originally bind to the first side section and the second side section of the support assembly may deflect upward and inward, and partially separate the binding between the two arms of the cushion and the first side section and the second side section of the support assembly. The force may push the middle part of the cushion downward. If the force is large enough, the middle part of the cushion may touch the upper side of the middle section of the support assembly such that the middle part of the cushion binds temporarily, via the complimentary patch of a reusable hook-and-loop fastener on the middle part of the cushion, to the middle section of the support assembly, via the patch on the upper side of the middle section. The downward curve of the middle section may facilitate the middle part of the cushion to move downward when the force is applied. If the support assembly includes a ribbon or band as already discussed, the length of the portion of the ribbon or band, located between the first side section and the second side section and substantially above the middle section of the support assembly, may be adjusted. The length of the portion of the ribbon or band may affect the stiffness of the cushion, or how much force is needed to push the cushion down toward the middle section of the support assembly. The contour of the upper side of the cushion may be such that it matches the contact surface of an intended subject, or a part thereof, well. The intended subject may be a person or user, or an object other than a person. The contact surface may be, e.g., a face or the back of the head of a user, or a part thereof.

The area 1706 may accommodate, e.g., a patch, such as a patch similar to or the same as the patches 1704 and 1705. It is understood that the support assembly 1710 may include more or fewer patches on either one of the first side section 1701, the second side section 1702, or the middle section 1703.
At least part of the support assembly 1710 may include at least one void. The void(s) may be through holes extending through the upper side and the underside of the part of the support assembly 1710. The void(s) may be non-through holes, extending only partially through the upper side and the underside of the part of the support assembly 1710. Merely by way of example, the first side section 1701 may include a plurality of voids on the underside thereof. The voids may be non-through holes. The voids may be arranged in a row, or more than one rows, along at least part of the length of the first side section 1701. The first side section 1701 is substantially parallel to the second side section 1702 along the length of both side sections. At least part of the second side section 1702 and/or the middle section 1703 may also include voids.
The connection assembly includes a first beam 1711, and a second beam 1712, and a beam connector including a shaft sleeve 1718 (described below in connection with FIG. 19A). The support assembly 1710 is connected with or coupled to, pivotally or otherwise, the connection assembly. For example, the first side section 1701 and the second side section 1702 of the support assembly 1710 are connected with or coupled to the beam connector of the connection assembly. At least part of the connection assembly may include at least one void 1732. The void(s) 1732 may be through holes extending through, e.g., the first beam 1711, the second beam 1712, or the beam connector, where the void(s) is or are located. The void(s) 1732 may be non-through holes, extending only partially through, e.g., the first beam 1711, the second beam 1712, or the beam connector, where the void(s) is or are located. Merely by way of example, the first beam 1711 may include a plurality of voids 1732. The voids 1732 may be non-through holes. The voids 1732 may be arranged in a row, or more than one rows, along at least part of the length of the first beam 1711. The first beam 1711 is substantially parallel to the second beam 1712 along the length of both beams. The voids 1732 may be located on the side of the first beam 1711 facing the second beam 1712 (referred to as the inner side of the first beam 1711). The voids 1732 may be located on another side of the first beam 1711, e.g., the outer side (opposite to the inner side), the upper side or the underside of the first beam 1711, or more than one side of the first beam 1711. The upper side of the first beam 1711 may face essentially the same direction as the upper side of the first side section 1701 when the first beam 1711 is in its unfolded configuration (as illustrated in FIG. 17B); the underside of the first beam 1711 is opposite to its upper side. Likewise, the upper side of the second beam 1712 may face essentially the same direction as the upper side of the second side section 1702 when the second beam 1712 is in its unfolded configuration (as illustrated in FIG. 17B); the underside of the second beam 1712 is opposite to its upper side. At least part of the second beam 1712 and/or the beam connector may also include one or more voids 1732.
The gear assembly may control, e.g., lock or unlock, the relative positioning of the support assembly 1710 of the cradle frame relative to, e.g., the beam connector or the table 100 shown in FIG. 16. Part of the gear assembly, a latch 1720, is shown in FIG. 17A. The latch 1720 may move in the directions as indicated by 1730, between an unlocked position 1720A as illustrated in phantom and a locked position 1720B. When the latch 1720 is in the unlocked position 1720A, the gear assembly allows for the movements of at least one of the parts including the first side section 1701, the second side section 1702 of the support assembly 1710, and the first beam 1711 and the second beam 1712 of the connection assembly; while when the latch 1720 is in the locked position 1720B, the gear assembly prevents the movements of these parts. The latch 1720 may include one or more void areas 1722. The void areas 1722 may include through holes, extending through the latch 1720 along one direction, e.g., the width direction W. The void areas 1722 may include non-through holes, extending only partially through the latch 1720 along one direction, e.g., the width direction W. The void areas 1722 may extend through or partially through the latch 1720 along a direction other than the width direction W.
FIG. 17B shows an exemplary cradle frame in a lower (or unraised) position with the beams 1711 and 1712 of the connection assembly in an unfolded configuration. As illustrated, the beams 1711 and 1712 are extended for coupling the cradle frame to a structure, e.g., the table 100 shown in FIG. 16. In this lower position, the first side section 1701 substantially aligns with the first beam 1711; likewise, the second side section 1702 substantially aligns with the second side beam 1712. The first beam 1711 and the second beam 1712 of the connection assembly are substantially parallel to each other. The first beam 1711 and the second beam 1712 as illustrated are substantially straight. It is understood that in other embodiments, one or both of the first beam 1711 and the second beam 1712 may be curved.
FIG. 17C shows an exemplary cradle frame in a raised position with the beams 1711 and 1712 of the connection assembly in an unfolded configuration. As illustrated, the beams 1711 and 1712 are extended for coupling the cradle frame to a structure, e.g., the table 100 shown in FIG. 16. In this higher (or raised) position, the first side section 1701 does not align with the first beam 1711; likewise, the second side section 1702 does not align with the second beam 1712. The beam connector including the shaft sleeve 1718 is located below or underneath the support assembly.
FIG. 17D shows an exemplary cradle frame with the beams 1711 and 1712 of the connection assembly in an unfolded configuration. FIG. 17D also shows the cushion 1750. The cushion 1750 shown in FIG. 17D may be put on the upper side of the support assembly 1710. The cushion 1750 may include one or more complimentary patches of reusable hook-and-loop fasteners that may fasten or bind temporarily with the patches 1704 and 1705 (and/or 1706 if available), on the upper side of the first side section 1701, and the upper side of the second side section 1702 (and/or the upper side of the middle section 1703 if available), respectively, during the time that the one or more complimentary patches on the cushion and the patches on the support assembly 1710 are pressed together. The patches and the complimentary patches may be separated by, e.g., peeling them apart.
FIGS. 18A and 18B show an exemplary cradle frame and the cushion 1750 when there is no force applied to the cushion 1750 (FIG. 18A) and when a force F is applied to the cushion 1750 (FIG. 18B). In both FIG. 18A and FIG. 18B, the exemplary cradle frame is in a lower (or unraised) position with the beams 1711 and 1712 of the connection assembly in an unfolded configuration, extended for coupling the cradle frame to a structure, e.g., the table 100 shown in FIG. 16. As shown in FIG. 18A, when there is no force applied to the cushion 1750, two arms of the cushion 1750 temporarily bind, via the complimentary patches of reusable hook-and-loop fasteners on the two arms of the cushion 1750 (invisible in FIG. 18A), to the support assembly 1710, via the patches 1704 and 1705 on the upper side of the first side section 1701 and the upper side of the second side section 1702, respectively. The middle part of the cushion 1750 does not bind to the middle section 1703 of the support assembly 1710 where the middle section 1703 is curved, e.g., downward. As shown in FIG. 18B, when the force F is applied to the cushion 1750, the two arms of the cushion 1750 that originally bind to the first side section 1701 and the second side section 1702 of the support assembly 1710 deflect, e.g., upward and inward, and partially separate the binding between the two arms of the cushion 1750 and the first side section 1701 and the second side section 1702 of the support assembly 1710. The force F pushes the middle part of the cushion 1750 downward toward the middle section 1703 of the support assembly 1710. If there is a patch located at 1706 of the middle section 1703, the cushion 1750 may bind temporarily, via the complimentary patch of a reusable hook-and-loop fastener on the middle part of the cushion 1750 (invisible in FIG. 3B), to the middle section 1703 of the support assembly 1710, via the patch located at 1706 on the upper side of the middle section 1703. The curve, e.g., a downward curve, of the middle section 1703 may facilitate the middle part of the cushion 1750 to move, e.g., downward, when the force F is applied.
FIG. 19A shows an exploded view of an exemplary cradle frame. The support assembly 1710 includes the first side section 1701, the second side section 1702, and the middle section 1703. The patch 1704 of a reusable hook-and-loop fastener is located on the upper side of the first side section 1701. Likewise, the patch 1705 of a reusable hook-and-loop fastener is located on the upper side of the second side section 1702. On the upper side of the middle section 1703, there may be the area 1706. The area 1706 may include a depression or indentation. The area 1706 may accommodate, e.g., a patch, such as one like 1704 or 1705, or a complimentary patch of the patch 1704 or 1705. The cradle frame 1710 may include a cavity for, e.g., holding an agent. The agent may include, e.g., at least one composition selected from the group consisting of a fragrance, an essential oil, and a medication, or the like. The cavity may house a wicking material, and the wicking material is configured to absorb and/or release the agent. Merely by way of example, the civility may be located at the first side section 1701, the second side section 1702, or the middle section 1703, e.g., the underside thereof.
The first side section 1701 may include a small crown gear 1772, and the second side section 1702 may include a small crown gear 1774. The small crown gear 1772 may be integrally formed with the first side section 1701 of the support assembly 1710. Likewise, the small crown gear 1774 may be integrally formed with the second side section 1702 of the support assembly 1710. The small crown gear 1772 may include a slot 1776 for accommodating a double end threaded stud 1719 (discussed below). Although invisible in FIG. 19A, the small crown gear 1774 may include a slot similar to the hole 1776 in the small crown gear 1772 for accommodating the double end threaded stud 1719 (discussed below). FIG. 19B shows a front view (in the A direction) of the exemplary support assembly 1710 illustrated in FIG. 19A.
Returning to FIG. 19A, the connection assembly includes the first beam 1711, the second beam 1712, and the beam connector. The beam connector includes a shaft sleeve 1718 and the double end threaded stud 1719.
The gear assembly includes the latch 1720, an internal thread connector 1752, large crown gears 1754 and 1760, springs 1756 and 1758, a self-locking nut 1762, and a cap 1764. The large crown gear 1754 may be integrally formed with the first beam 1711; likewise, the large crown gear 1760 may be integrally formed with the second beam 1712.
