[0002] (1. Field) Embodiments of the present teachings are directed to a convertible platform for supporting a user. Specifically, embodiments of the present teachings are directed to a convertible platform comprising an attachment device for supporting a pediatric patient in a standing position and / or a sitting position.

Background Art

[0003] (Background) (2. Related Art) In a typical household with a pediatric patient, many pediatric care devices are used to assist in performing various tasks to meet the needs of the pediatric patient and the caregiver. For example, a high chair can be utilized for a pediatric patient to sit at a convenient height for the caregiver to interact with the pediatric patient while eating and playing. A step - footrest can be utilized for a pediatric patient to reach a countertop or sink. These pediatric care devices are typically used once a day, for example, during dinner time or play time. When not in use, these pediatric care devices are cumbersome to handle and typically sit within the kitchen or dining area, cluttering up the available space.

[0004] Furthermore, when pediatric furniture devices are used, they typically are not adjustable for growing children, and children grow quickly, rendering the pediatric furniture device unable to support larger children or adults. Furniture devices for larger children are no longer usable and must be disposed of after only one or two years of use.

[0005] What is needed is a convertible platform with a support base that supports a mounting device configurable to support users of any age and size in seated and standing positions.

The embodiments are intended to describe aspects of the present teachings in sufficient detail to enable one skilled in the art to practice the present teachings. Other embodiments may be utilized and changes may be made without departing from the scope of the present teachings. The following detailed description, therefore, should not be taken in a limiting sense. The scope of the present teachings is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled.

[0030] In this description, references to "one embodiment," "an embodiment," or "embodiments" mean that the feature or features being referred to are included in at least one embodiment of the technology. Separate references to "one embodiment," "an embodiment," or "embodiments" in this description do not necessarily refer to the same embodiment, and are not mutually exclusive, unless so stated and / or unless readily apparent to one skilled in the art from the description. For example, features, structures, acts, etc. described in one embodiment may also be included in other embodiments, but not necessarily. Thus, the technology can include various combinations and / or integrations of the embodiments described herein.

[0031] Generally, embodiments of the present disclosure relate to a convertible platform comprising a base for receiving a selectively attachable attachment device to support users such as infants, toddlers, children, and in some embodiments, adults. The base may be foldable for storage in a folded configuration or deployed to a deployed configuration for use. The base may receive and secure steps for the user to climb up to the selectively attachable attachment device. The base may comprise a base attachment member for attaching the attachment device. In some embodiments, the base attachment member may be an extension of or an end of the front leg. In some embodiments, the attachment device may comprise a chair, seat, platform, guardrail, bathtub, bassinette, and the like for supporting a user in a standing position and a seated position. In some embodiments, the attachment device may provide some form of entertainment or education and may be an easel, abacus, blackboard, whiteboard, touch screen, or the like. For example, the attachment device may be a high chair and may provide a seat for a child to sit in and be strapped in for securing. The guardrail may be attached to the base and may provide a 360-degree rail for holding while the child is standing. In some embodiments, the convertible platform may support users of any age or size in a seated position or a standing position.

[0032] Figure 1 depicts a convertible platform 10 comprising a base 12 and an attachment device 14. In the configuration shown, the convertible platform 10 is configured to support a user within the attachment 14, which in the illustrated embodiment is a high chair 16 for supporting a child. In some embodiments, the attachment device 14 may be selectively attachable to the base 12. Thus, the high chair 16 may be removed and replaced, for example, with the backrest 52 (FIG. 3), guardrail 46 (FIGS. 4A - 4B), or any other exemplary attachment device 14 described herein.

[0033] In some embodiments, the front legs 18 and the rear legs 20 include attachment points 22. The front legs 18 may be one, a set, or a plurality of legs that cooperate with one, a set, or a plurality of rear legs 20 to support the user and the attachment device 14. The front legs 18 and the rear legs 20 may be connected at a pivot hinge 24. The pivot hinge 24 may allow the front legs 18 to pivot relative to the rear legs 20 about the pivot hinge 24 and provide an angle 26 between the front legs 18 and the rear legs 20. The angle 26 between the front legs 18 and the rear legs 20 may range from an angle as small as zero degrees, which provides a folded configuration (FIG. 7), to an angle greater than 45 degrees or any angle up to an angle that provides a configuration as shown in FIG. 1 therebetween. Further, the pivot hinge 24 may provide a blocking or locking mechanism to prevent rotation of the front legs 18 beyond a defined angle relative to the rear legs 20. Thus, the front legs 18 and the rear legs 20 provide a stable base for the user and the attachment device 14.

[0034] In some embodiments, the convertible platform 10 may be configured to support infants and / or adults up to a defined weight. The convertible platform 10 may include lateral struts 28 and lower struts 30 that provide stability. In some embodiments, the lateral struts 28 and lower struts 30 may be a plurality of lateral struts and may be disposed between each of the front legs 18 and / or each of the rear legs 20. The lateral struts 28 and lower struts 30 may be provided between any of the legs of the base 12 to assist with stability and structural integrity and may add a structure to prevent separation of adjacent legs. Further, the lateral struts 28 and lower struts 30 may add weights near the floor to the base 12 to lower the center of gravity of the convertible platform 10 and provide an increase in safety for a user sitting above the center of gravity. The lateral struts 28 and lower struts 30 may be made of wood, plastic, metal, or any combination of materials, similar to any part of the convertible platform 10, and may be attached to the front legs 18 and rear legs 20 by screws, bolts, snaps, or any other fasteners. In some embodiments, the lateral struts 28 and / or lower struts 30 may be molded or welded as a single piece base 12. In some embodiments, the convertible platform 10 may be configured to support infants up to 100 pounds and / or adults up to 300 pounds. Thus, it is to be understood that convertible platforms 10 of various sizes of elements and materials may be manufactured for expected users of various shapes and sizes.

[0035] In some embodiments, the lower support 30 includes a standing leg portion 32. The standing leg portion 32 is made of any material that modifies the contact between the lower support 30 and the underlying surface (e.g., the floor). In some embodiments, the standing leg portion 32 may be made of rubber, plastic, felt, and / or any material suitable for the use of the convertible platform 10. In some embodiments, the standing leg portion 32 may be soft so that the standing leg portion 32 does not damage the floor. Further, the standing leg portion 32 may be a material with a high coefficient of friction to reduce slipping on a typical floor.

[0036] The convertible platform 10 can be presented in various embodiments that include various steps and footrests at various locations provided by the attachment points 22. The steps and footrests are interchangeable and can be selectively attached at any of the attachment points 22 and may support people of any shape and size with various heights and leg lengths. In some embodiments, the base 12 may further include a step 34 that leads up into the high chair 16 or serves as a footrest. The step 34 as well as the platform 36 may be installed at any attachment point 22. Thus, any arrangement of platforms 36 and steps 34 is conceivably provided by the attachment points 22. As shown in FIG. 1, the platform 36 is used as a footrest / step and the step 32 is used as a step to reach the high chair 16. In some embodiments, the platform 36 may be used as a step, seat, table, or any other use. The platforms 36 and steps 34 are discussed in more detail in the further embodiments below.

[0037] FIG. 2 depicts the base 12, which includes a front leg 18, a rear leg 20, a step 34, a platform 36, and a base attachment member 38. In some embodiments, one, a set, or a plurality of base attachment members 38 are an extension of the front leg 18 and are configured to selectively attach the attachment device 14. The attachment device 14 may be the high chair 16, the backrest 52 (FIG. 3), the guard rail 46 (FIGS. 4A-4B), or any other attachment device described herein. Here, the exemplary guard rail 46 is depicted. Any attachment device is conceivable.

[0038] In some embodiments, the front leg 18 may extend beyond the pivot hinge 24 and provide a base attachment member 38 for inserting or receiving the attachment device 14 therein. Further, the attachment device 14 may include one, a set, or a plurality of attachment device attachment members 40 for inserting or receiving the base attachment member 38 therein. The base attachment member 38 may be disposed on the end of the proximal front leg 18 of the attachment device 14 above the pivot hinge 24. In some embodiments, the base attachment member 38 may include a cross-sectional area 48 that is slightly smaller than the inner surface 50 of the attachment device attachment member 40. Thus, the base attachment member 38 may slide into the attachment device attachment member 40 as shown. The base attachment member 38 may then support the attachment device 14 by securing the attachment device attachment member 40 inside the base attachment member 38 as shown.

[0039] In some embodiments, the attachment device attachment member 40 may include a cross-sectional hollow portion that is larger than the outer surface of the base attachment member 38. Thus, in some embodiments, the base attachment member 38 may receive the attachment device attachment member 40. As shown, the guard rail 46 includes an attachment device attachment member 40 configured to receive the base attachment member 38.

[0040] In some embodiments, the base attachment member 38 may include a base locking mechanism 42 for interaction with an attachment locking mechanism 44 that locks the fixture 14 in a fixed position on the base 12. The base locking mechanism 42 may be spring-loaded and / or may be a compressible protrusion that is depressed when the attachment device attachment member 40 slides over the base locking mechanism 42. When the base locking mechanism 42 is depressed, the base attachment member 38 may receive the attachment device attachment member 40. In some embodiments, the attachment locking mechanism 44 may be a hole or socket for receiving the base locking mechanism 42, which may be a spring-loaded ball or shaft in some embodiments. When the attachment locking mechanism 44 slides over the base locking mechanism 42, the base locking mechanism 42 may extend into the attachment locking mechanism 44 and lock the attachment device 14 in a fixed position. Similarly, to remove the attachment device 14 from the base 12, the user may depress the base locking mechanism 42, pull the attachment device 14 away from the base 12, and slide the attachment device attachment member 40 away from the base attachment member 38.

[0041] In some embodiments, the base attachment member 38 may be an extension of the front leg 18. Thus, the angle of the fixture relative to the floor may be based on the angle 26. For example, as depicted in FIG. 2, the wider the angle 26, the more the front leg 18 will recline, and as a result, the guard rail 46 will recline more. The attachment device 14 is attached to the front leg 18, and since the front leg 18 requires a minimum angle to support the attachment device 14 and the user, the angle of the attachment device 14 relative to the floor may be based on the angle 26. The relative recline of the attachment device 14 based on the angle 26 is discussed in more detail below.

[0042] In some embodiments, the base attachment member 38 may be hollow and may receive the attachment device attachment member 40 therein. The attachment locking mechanism 44 may project from the attachment device attachment member 40 by a spring that biases the projection. The base locking mechanism 42 may be a hole configured to receive the projecting attachment locking mechanism 44. The user may slide the device attachment member 40 into the hollow portion of the base attachment member 38. When the attachment locking mechanism 44 moves across the base locking mechanism 42 (hole), the attachment locking mechanism 44 may extend into the base locking mechanism 42 that locks the attachment device 14 (e.g., the guard rail 46 of FIG. 2) in place. The user may simply push down on the attachment locking mechanism, thereby compressing the internal spring and allowing the attachment device 14 to be removed from the hollow portion of the base attachment member 38.

[0043] FIG. 3 depicts the base 12 in a chair configuration comprising a backrest 52 and a platform 36 that provides a seat for a user. In some embodiments, the platform 36 may be attached to the front legs 18 such that the platform 36 acts as a seat providing a sitting or standing surface or a surface on which the base 12 rests that is substantially parallel to the floor / ground. In some embodiments, the attachment point 22 is angled with respect to the front legs 18 such that the attachment point 22 provides a groove that is substantially parallel to the floor and provided on the inner surface side of the front legs 18. When the base 12 is fully open with respect to the standing configuration (e.g., the angle 26 is at a maximum), the attachment point 22 may provide a groove parallel to the floor on which the convertible platform 10 stands. Thus, the platform 36 may be substantially parallel to the floor. The platform 36 may provide a seat, step, shelf, or any platform for a user and / or object. The attachment device 14 may thus be in a reclined position based on the angle 26 and similarly based on the angle of the front legs 18 to the floor. Each attachment device 14 may be designed to provide an angle that is sufficiently comfortable for the user depending on the configuration of the convertible platform 10 comprising the attachment device 12.

[0044] Figure 3 depicts the exemplary backrest 52. The backrest 52 may be attached to the base attachment member 38 at the attachment device attachment member 40. Here, the attachment device attachment member 40 has a hollow cross-section that is slightly larger than the outer surface of the base attachment member 38. Thus, the attachment device attachment member 40 may receive the base attachment member 38. Any of the base locking mechanisms 42 and attachment locking mechanisms 44 described above may be used to lock the backrest 52 to the base 12. The backrest 52 may be designed to provide a reclining support for a user sitting on the platform 38 while considering the angle 26. The rear portion 54 of the backrest 52 may be substantially aligned with the front legs 18, or may be slightly angled forward or backward to provide a comfortable reclined seating position. Further, the rear portion 54 may be concave, made of a soft material, and may provide a comfortable position for the user.

[0045] As shown, the base attachment member 38 is a direct linear extension of the front legs 18. However, the base attachment member 38 may be angled from the front legs 18 to provide an angle for the attachment device 14. The base attachment member 38 may be angled with respect to the front legs 18, for example, such that the high chair 16 provides a flat or slightly reclined surface for seating and a reclined backrest, the guard rail 46 is horizontal, and the backrest 52 is reclined, to provide a comfortable angle for the attachment device 14.

[0046] In some embodiments, the step 34 and the platform 36 may be selectively attached to the front leg 18 and the rear leg 20 at the attachment point 22. As described above, the attachment point 22 may provide a flat groove (parallel to the floor) for receiving and supporting the step 34 and / or the platform 36. The attachment point 22 may provide a step 34 and a platform 36 that are angled with respect to the front leg 18 based on the angle 26 and are substantially parallel to the floor. This allows a user to climb onto the platform 36 in the chair configuration shown in FIG. 3 and sit thereon. In this exemplary embodiment, the user may be of any age and size. The step 34 and the platform 36 may be set to any height based on the size of the user or may provide a shelf for an object. Thus, the convertible platform 10 may provide a seat for users of any age, size, and shape. Embodiments of the backrest 52 may be of plastic, wood, fabric, rubber, foam, or any combination of materials.

[0047] Figures 4A-4C depict an exemplary guard rail 46 for attachment to the base 12. FIG. 4A depicts a guard rail 46 that substantially surrounds 180 degrees of a user supported on the platform 36. In some embodiments, the guard rail 46 provides a support for a child to grasp while standing on the platform 36. The child may use the step 34 to climb onto the platform 36 and hold the guard rail 46 for support while standing. The first end 56 of the guard rail 46 may be attached to the first base attachment member 58, and the second end 60 of the guard rail 46 may be attached to the second base attachment member 62, and the guard rail may be continuous therebetween and provide a single 180-degree support guard rail 46. In some embodiments, the guard rail 46 substantially covers 180 degrees as shown in FIG. 4A, and in some embodiments, the guard rail 46 substantially covers 360 degrees as shown in FIG. 4B and surrounds the child.

[0048] FIG. 4B depicts a platform 36 that connects to both the front leg 18 and the rear leg 20 at the front attachment point 22a and the rear attachment point 22b. In some embodiments, the platform 36 may be configured to couple to either the front leg 18 or the rear leg 20, or both the front leg 18 and the rear leg 20. The platform 36 may slide into the attachment points 22 and be held in place based on friction, or a platform fixture 37 may hold the platform 36 in place.

[0049] In some embodiments, the platform 36 may include a platform fixture 37. The platform fixture 37 may be spring-loaded to lock the platform 36 into the front attachment point 22a and the rear attachment point 22b. The platform fixture 37 may be a small protrusion that can be pushed down into the side of the platform 36 when manually pressed therein or when the platform 36 is slid into place. For example, the platform fixture 37 may be angled such that when the platform 36 is slid into place to be locked between the front leg 18 and the rear leg 20, the acute angle on the platform fixture provides a force against the rear leg, compressing an internal spring and pushing down the platform fixture 37. Further, the side of the platform fixture 37 that contacts the rear leg 20 may be configured at an angle closer to 90 degrees such that when pressed against the rear leg 20, it does not allow the platform fixture 37 to be pushed down. A user may manually push down the platform fixture 37, slide the platform 36 out, and remove the platform 36 from between the legs. This locks the platform 36 in place between the front leg 18 and the rear leg 20 and prevents unwanted movement of the platform 36. Similarly, or alternatively, the platform fixture 37 may be disposed in the vicinity of the front leg 18 and function as described above in relation to the rear leg 20.

[0050] Figure 4C depicts an embodiment with a protective rail 46 that provides substantially 360-degree support. As shown, the protective rail 46 may provide continuous 360-degree support around the user. Further, in some embodiments, one of the sides of the protective rail 46 may provide a door and hinge (not shown) that opens and closes securely, providing an access or entry and exit point for the user. The door and hinge may lock securely, allowing the protective rail 46 to be used without the child accidentally opening the door.

[0051] In some embodiments, any portion of the platform 36 shown in 4B may be added to or combined with the platform 36 shown in any of the other figures described herein. In some embodiments, the platform 36 includes an edge 64. The edge 64 may be a raised portion near the edge of the platform 36 that provides tactile feedback to the user while standing. The user may stand on the platform 36 and perceive the edge 64 with their feet. The edge 64 may provide tactile feedback to the user to understand where the edge of the platform 36 is present and not step off the edge.

[0052] Furthermore, platform 36 may include a drip tray 66 and / or a channel (not shown) for receiving overflows. For example, if a child standing on platform 36 overflows a liquid, the liquid may be captured within drip tray 66 or the channel and collected away from the child's feet. Drip tray 66 may be provided beneath upper surface 68 of platform 36. Drip tray 66 may be easily removable and disposable as well as cleanable. In some embodiments, holes 70 may be provided within upper surface 68 of platform 36 to receive any overflowed liquid and transport it to drip tray 66, keeping upper surface 68 dry for the child. In some embodiments, upper surface 68 of platform 36 and / or step 34 includes treads for providing a high friction surface for the child to stand on. The high friction surface may provide a gripping portion for the child's feet or shoes so that the child does not easily slide on platform 36 when it is wet.

[0053] In some embodiments, guardrail 46 may be attached to base 12 by base attachment member 38 and attachment device attachment member 40 as described above. Further, base attachment member 38 and attachment device attachment member 40 may provide an adjustable height for guardrail 46 for children of various heights. As described above, a plurality of locking mechanisms may be disposed on base attachment member 38 and attachment device attachment member 40 to enable height adjustment of attachment device 14.

[0054] Illustrated in FIG. 5A is an embodiment of a high chair 16 for supporting an infant in a seated position. In some embodiments, the high chair 16 may be selectively attached to the base 12 by an attachment device attachment member 40 that interacts with the base attachment member 38, as described above. In some embodiments, the attachment device attachment member 40 may be slightly larger than the base attachment member 38 to receive the base attachment member 38 in a telescoping manner. In some embodiments, the high chair 16 may include a concave seat 74 for receiving the infant. The concave seat 74 may be U-shaped to provide free movement of the infant's legs. The U-shape of the concave seat 74 may provide an unobstructed area for the infant's legs to move freely while maintaining fixation for the infant by a strap (not shown). The strap may be provided between the infant's legs and wrapped around the infant's waist and connected to the high chair 16 to secure the infant. In some embodiments, the concave seat 74 includes sidewalls 76 for providing lateral support to the seated infant.

[0055] In some embodiments, the high chair includes an adjustable backrest 78 for supporting the infant's back and sides. The adjustable backrest 78 may again be U-shaped to connect the concave seat 74 and the sidewalls 76 to wrap around the infant's body. In some embodiments, the adjustable backrest 78 includes shoulder straps (not shown) for securing the infant's upper torso. The shoulder straps and the plurality of straps may be attached by snaps, click mechanisms, hook-and-loop fasteners, buttons, or any other fastening device.

[0056] In some embodiments, the adjustable backrest 78 includes an adjustable section 80 that slides vertically to provide height adjustment to support children of various sizes. The adjustable section 80 may slide under force, under friction, or maintain its position by any backrest locking mechanism (not shown). The backrest locking mechanism may be a latching portion provided as a deformable lever with a hook that snap-fits across a protrusion to lock the adjustable section 80 in place. The user may press the lever to release the latching portion and press to move the adjustable section 80 to a different position. A plurality of heights may be provided for children of various sizes.

[0057] In some embodiments, the high chair 16 includes a selectively attachable tray 82. The selectively attachable tray 82 may provide a table for the child to eat or play on. In some embodiments, the selectively attachable tray 82 may include clips for snap-fitting onto the sidewalls 76. In some embodiments, the selectively attachable tray 82 snap-fits and / or slides onto the sidewalls 76.

[0058] FIG. 5B depicts an exemplary attachment mechanism between the selectively attachable tray 82 and the sidewall 76. The selectively attachable tray 76 may include a lever 96 and a pin 98. In some embodiments, the selectively attachable tray 82 may slide onto the sidewall 76, and the pin 98 may be pushed into the side of the selectively attachable tray 82 by compressing a spring or lever. A hole (not shown) in the sidewall 76 may be configured to receive the pin 98 such that when the pin 98 slides across the hole, the pin 98 extends into the hole and locks the selectively attachable tray 82 in place on the sidewall 76.

[0059] In some embodiments, the lever 96 may be configured to receive a compressive force that provides an internal spring or resistance by the lever. The lever 96 may be mechanically coupled to the pin 98 and may cause the pin 98 to be pushed down when a force is applied to the lever 96. When the lever 96 is pressed and as a result the pin 98 is pushed down, a selectively attachable tray may slide easily on and away from the sidewall 76.

[0060] Figures 6A and 6B depict an embodiment with a step 34. As shown, the step 34 is a U-shaped step configured to be attached between the front legs 18.

[0061] In some embodiments, step 34 may be a reversible step that provides an intermediate (at least two) height between attachment points 22. The reversible step may be U-shaped and may be secured within the grooves of attachment points 22 as described above. The reversible step may provide a progressive height change for a child. FIG. 6A depicts a progressive step in an arch configuration and FIG. 6B depicts a progressive step in a U-shaped configuration. The reversible step may provide a platform intermediate the attachment points 22 such that the steps 34 depicted in FIGS. 1-4B provide a platform at each attachment point 22. The reversible step may be secured within the groove with the U-shaped portion upright and may reduce the distance between the user, who is within attachment device 14 or seated on platform 36, as shown in FIG. 6A. Alternatively, the reversible step may be configured in a U-shaped configuration that extends the distance between the reversible step and the user, who is within attachment device 14 or seated on platform 36. Thus, the U-shaped step may provide a progressive platform for a child to climb onto platform 36 or attachment device 14. Further, the reversible step may provide a platform for the user to rest their feet while seated on platform 36 or attachment device 14.

[0062] Figure 7 depicts the base 12 in a folded configuration for storage. In some embodiments, the front leg 18 and the rear leg 20 may rotate about the pivot hinge 24. In some embodiments, the pivot hinge 24 may be spring-loaded such that, in the locked position, the front leg 18 and the rear leg 20 may both be locked and unable to rotate. When a force is applied to the pivot hinge 24, the locking mechanism may compress the spring and slide inwardly to release the front leg 18 from the rear leg 20 and allow rotation. Further, the rear leg 20 may be configured such that, when rotated, the rear leg 20 may slide adjacent to and on the outside of the front leg 18. Thus, the base 12 may be folded into a folded configuration in which the space occupied by the convertible platform 10 is reduced. Any attachment device 14 may be attached or removed while the base 12 is in the folded configuration shown in FIG. 7. When the front leg 18 and the rear leg 20 are configured to support the attachment device 14, the pivot hinge 24 may be installed in the locked position again.

[0063] In some embodiments, the attachment device 14 may be various devices for supporting a child in various ways and for various purposes. The embodiments of the attachment device 14 described herein may be non-limiting. For example, the attachment device 14 may be a bassinet, a bathtub, a diaper changing table, an easel, an abacus, a drawing board, a touch screen, or any other device that may assist and / or facilitate entertainment, education, and / or any other use by an infant, a toddler, a child, or an adult. Any of the alternative attachment devices may be attached to the base 12 as described above and may be designed for the angle 26 to provide the necessary configuration for each alternative embodiment. In some embodiments, the attachment device 14 may be an automobile seat, and the base 12 may be adaptable to be attached to an automobile seat, or the automobile seat may include an attachment device member 40 for attachment to the base attachment member 28.

[0064] Figures 8A-8C depict a convertible base platform 84 for coupling to or supporting on a surface the attachment device 14. In some embodiments, the convertible base platform 84 may comprise a base platform 86 configured to rest on a surface and provide support for the attachment device 14, the user, and / or an object. In some embodiments, the attachment device 14 may be a high chair 16 as shown, or any other attachment device 14 as described herein. In some embodiments, the convertible base platform 84 comprises a base attachment portion 88 having at least one slot 90 for receiving an attachment portion (not shown) of the attachment device 14.

[0065] In some embodiments, the base attachment portion 88 may be a rectangular protrusion having the slot 90. The rectangular protrusion may similarly be provided by an attachment portion of the attachment device 14. In some embodiments, the attachment portion of the attachment device 14 may be slightly larger or slightly smaller than the base attachment portion 88 and provide a secure attachment. In some embodiments, the rectangular protrusion may be of any shape including a square, triangle, rounded shape, any polygon, irregular shape, or any other shape. Further, the attachment portion of the attachment device 14 may be of a similar shape to provide translational and rotational resistance, prevent tipping, and secure the convertible base platform to the attachment device 14.

[0066] In some embodiments, the attachment portion of the attachment device 14 may provide at least one protrusion for reception by at least one slot 90. The at least one protrusion may slide securely into the slot 90 and provide additional translational and rotational support. Thus, the attachment device 14 may be securely attached to the convertible base platform 86 to support a user or an object.

[0067] In some embodiments, the convertible base platform 84 includes a strap 86 for securing the convertible base platform 84 to a surface. In some embodiments, the strap 92 may be a plurality of straps. The strap 92 may be made of any material, including fabrics and plastics, that is flexible enough to wrap around the surface and strong enough to secure the convertible base platform 84. In some embodiments, the surface may be a floor, chair, table, or the like. The surface may be any substantially flat surface that is sufficient to support the convertible base platform 84, mounting device 14, and any user or object described herein. If the surface is a chair, table, or other object that is lifted off the floor, the strap 90 may wrap around the lifted object to provide additional translational and rotational resistance and prevent sliding and tipping.

[0068] Figure 9 depicts an exemplary method 900 for deploying the base and changing the mounting device. In step 902, the base 12 may be reconfigured from a folded configuration to a deployed configuration. In some embodiments, the user may activate the pivot hinge 24 to allow the front leg 18 to rotate about the pivot hinge 24 relative to the rear leg 20. As the front leg 18 rotates relative to the rear leg 20, the angle 26 may become larger, providing a wide support base for the base 12 to rise up. The base 10 may be seated in an upright position with the standing leg 32 on the floor at the distal end of the front leg 18 and the base mounting member 38 at the proximal end of the front leg 18. The base mounting member 38 may be positioned to receive the mounting device 14.

[0069] In step 904, the base may be locked in place at an angle 24 of maximum or desired angle. The maximum angle may be stopped by a stop mechanism that stops the rotation of the front leg 18 relative to the rear leg 20, or may be provided by a locking mechanism that can be automatic or manual. The locking mechanism for the pivot hinge may lock according to the embodiments described above. The pivot hinge 24 may lock such that the base 12 provides a stable base for supporting the mounting device 14 and the user. Further, the pivot hinge 24 may be locked at an angle 26 that provides an appropriate angle such that the mounting device 14 is at a desired angle and the attachment point 22 is substantially parallel to the floor.

[0070] In step 906, the mounting device 14 and other fixtures may be added to the base 12 to complete the deployment of the convertible device 10. Once the base 12 is deployed, the mounting device 14, platform 36, step 34, and any other fixtures may be added to the base 12. The step 34 and / or platform 36 may be added at the attachment point 22 to provide a groove parallel to the floor. The step 34 and platform 36 may be provided in a state substantially parallel to the floor by any of the attachment points 22.

[0071] The mounting device 14 may be attached to the base 12 by the interaction between the mounting device attachment member 38 and the base attachment member 40 described above. The mounting device 14 may be any of the high chair 16, guard rail 46, backrest 52, or any other mounting device 14 described above. In step 908, the mounting device 14 may be locked in place on the base 12 by the interaction between the base locking mechanism 42 and the mounting locking mechanism 44 as described in the above embodiments.

[0072] In step 910, the user may be supported by the convertible platform 10. In some embodiments, the user may climb the steps 34 and the platform 36 and sit or otherwise be supported within the mounting device 14. As described above, in some embodiments, the user may sit within the high chair 16, sit on the platform 36, stand on the platform 36, and hold the guard rail 46.

[0073] When the user finishes using the convertible platform 10 in step 912, the user may exit the convertible platform 10, and the mounting device 14, the steps 34, and the platform 36 may be removed. The mounting device 14 may be removed by engaging the mounting locking mechanism 44 and / or the base locking mechanism 42 and releasing the mounting device 46, as described above.

[0074] In step 914, the convertible platform 10 may be placed in a folded configuration and stored. The pivot hinge 24 may be engaged to release the pivot hinge locking mechanism and allow the front legs 18 to rotate about the pivot hinge 24 relative to the rear legs 20. The front legs 18 may be slightly narrower than the rear legs 20 near the pivot hinge 24, allowing the rear legs 20 to fold close to the front legs 18 and occupy a smaller space than the convertible platform 10 in the deployed configuration, allowing for a smaller configuration.

[0075] Although the present disclosure has been described with reference to the embodiments illustrated in the accompanying drawings, it should be noted that equivalents may be employed and substitutions may be made herein without departing from the scope of the present disclosure as recited in the claims.

[0076] Although the various embodiments of the present disclosure have been described as above, what is desired to be newly claimed and protected by a patent is claimed to include the following.
