Specifically, embodiments of the present disclosure relate to convertible platforms that include attachment devices for supporting a child in a standing position and / or a sitting position. Background Art

[0004] In a typical home with children, many child furniture devices are used to assist with various tasks to meet the needs of both the child and the parents. For example, a high chair can be used to seat a child at a certain height, allowing parents to interact with the child during mealtimes and playtimes. A step stool can be used by a child to reach a countertop or sink. These child furniture devices are typically used once a day during dinnertime or playtime. When not in use, these child furniture devices can be bulky and are often placed in the kitchen or dining area, cluttering up the available space.

[0005] Furthermore, when children's furniture units are used, they are often not adjustable to the child's growth and the child quickly becomes too large for the furniture unit to support the larger child or adult. Large children's furniture units become unusable and must be discarded after one or two years of use.

Other embodiments may also be adopted and modified without departing from the scope of the present disclosure. Therefore, the following detailed description is not restrictive. The scope of the present disclosure is defined only by the appended claims and the full range of equivalents to which these claims are entitled.

[0031] In this specification, "one embodiment", "embodiment" or "multiple embodiments" means that one or more features mentioned are included in at least one embodiment of the technology. "One embodiment", "embodiment" or "multiple embodiments" mentioned in this specification do not necessarily refer to the same embodiment and are not mutually exclusive, unless otherwise specified and / or it is easy for a person skilled in the art to see from the description. For example, features, structures, actions, etc. described in one embodiment may also be included in other embodiments, but not necessarily. Therefore, the technology can include various combinations and / or integrations of the embodiments described herein.

[0032] In general, embodiments of the present disclosure relate to a convertible platform, which includes a base for receiving an attachment device that can be selectively attached to support a user, such as an infant, a toddler, a child, and an adult in some embodiments. The base can be foldable so that it can be stored in a folded structure, or it can be unfolded into an unfolded structure for use. The base can receive and fix steps so that the user climbs the base and climbs to the attachment device that can be selectively attached. The base can include a base attachment member for attaching the attachment device. In some embodiments, the base attachment member can be an extension of the front leg or an end of the front leg. In some embodiments, the attachment device can include a chair, a seat, a platform, a guardrail, a bathtub, a cradle, etc., for supporting a user in a standing position and a sitting position. In some embodiments, the attachment device can provide a form of entertainment or education, and can be an easel, an abacus, a blackboard, a whiteboard, a touch screen, or a similar device. For example, the attachment device can be a high chair, providing a seat for a child to sit on, and restraining the child in the seat to ensure safety. Guardrails can be attached to the base to provide a 360 degree guardrail for the child to hold onto when standing. In some embodiments, the convertible platform can support users of any age or size in a sitting or standing position.

[0033] Figure 1 A convertible platform 10 is shown that includes a base 12 and an attachment device 14. In the illustrated configuration, the convertible platform 10 is configured to support a user in the attachment 14, which in the illustrated embodiment is a high chair 16 for supporting a child. In certain embodiments, the attachment device 14 may be selectively attached to the base 12. Thus, the high chair 16 may be removed and replaced with, for example, a backrest 52 ( Figure 3 )、Guardrail 46( Figure 4A-4B ) or any other exemplary attachment device 14 described herein.

[0034] In some embodiments, the front leg 18 and the rear leg 20 include an attachment site 22. The front leg 18 can be one, a group of, or a plurality of legs that are used in conjunction with one, a group of, or a plurality of rear legs 20 to support a user and the attachment device 14. The front leg 18 and the rear leg 20 can be connected at a pivot hinge 24. The pivot hinge 24 can allow the front leg 18 to rotate relative to the rear leg 20 about the pivot hinge 24, thereby forming an angle 26 between the front leg 18 and the rear leg 20. The range provided by the angle 26 between the front leg 18 and the rear leg 20 can be as small as zero degrees to provide a folded configuration ( Figure 7 ), to greater than 45 degrees, or any angle in between, to provide Figure 1 In addition, the pivot hinge 24 can also provide a blocking or locking mechanism to prevent the front leg 18 from rotating relative to the rear leg 20 beyond a specified angle. Therefore, the front leg 18 and the rear leg 20 provide a stable base for the user and the attachment device 14.

[0035] In some embodiments, the convertible platform 10 can be configured to support children and / or adults, but the weight must not exceed a specified weight. The convertible platform 10 can include a transverse support bar 28 and a lower support bar 30 that provide stability. In some embodiments, the transverse support bar 28 and the lower support bar 30 can be multiple transverse support bars and can be disposed between each front leg 18 and / or each rear leg 20. The transverse support bar 28 and the lower support bar 30 can be disposed between any legs of the base 12 to increase the stability and structural integrity of the structure and prevent adjacent legs from separating. In addition, the transverse support bar 28 and the lower support bar 30 can increase the weight of the base 12 close to the floor, lowering the center of gravity of the convertible platform 10, thereby improving the stability of the user sitting above the center of gravity. Like any part of the convertible platform 10, the transverse support bar 28 and the lower support bar 30 can include wood, plastic, metal, or any combination of materials, and can be attached to the front leg 18 and the rear leg 20 by screws, bolts, snaps, or any other fasteners. In some embodiments, the lateral support bar 28 and / or the lower support bar 30 may be molded as a single component of the base 12 or may be welded. In some embodiments, the convertible platform 10 may be configured to support a child weighing no more than 100 pounds and / or an adult weighing no more than 300 pounds. Therefore, it should be understood that the size and materials of the various elements of the convertible platform 10 may be manufactured according to the various shapes and sizes of the intended users.

[0036] In some embodiments, the lower support bar 30 includes a foot 32. The foot 32 includes any material that can change the contact between the lower support bar 30 and the underlying surface (e.g., the floor). In some embodiments, the foot 32 can include rubber, plastic, felt, and / or any material suitable for the application of the convertible platform 10. In some embodiments, the foot 32 can be soft so that the foot 32 does not damage the floor. In addition, the foot 32 can be a material with a higher coefficient of friction to reduce slipping on typical floors.

[0037] The convertible platform 10 can be presented in different embodiments, including various steps and footrests provided by the attachment site 22 at different locations. The steps and footrests can be interchangeable and can be selectively attached at any of the attachment sites 22 to support various heights and leg lengths of people of all shapes and sizes. In some embodiments, the base 12 can also include a step 34 for stepping onto the high chair 16 or as a footrest. The steps 34 and platform 36 can be placed on any of the attachment sites 22. Thus, the attachment site 22 can provide any arrangement of the platform 36 and steps 34. Figure 1 As shown, the platform 36 is used as a footrest / step and the step 32 is used as a step leading to the high chair 16. In certain embodiments, the platform 36 can be used as a step, a seat, a table or any other application. The following embodiments will further discuss the platform 36 and the step 34 in detail.

[0038] Figure 2 The base 12 is shown to include 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 group, or a plurality of base attachment members 38 are extensions of the front leg 18 and are configured for selective attachment of the attachment device 14. The attachment device 14 may be a high chair 16, a backrest 52 ( Figure 3 )、Guardrail 46( Figure 4A-4B ) or any other attachment means described herein. An exemplary guardrail 46 is described here. Any attachment means is contemplated.

[0039] In some embodiments, the front leg 18 can extend beyond the pivot hinge 24 to provide a base attachment member 38 for inserting or receiving the attachment device 14. In addition, the attachment device 14 can include one, a group or a plurality of attachment device attachment members 40 for inserting or receiving the base attachment member 38. The base attachment member 38 can be disposed on the end of the front leg 18 near the attachment device 14 above the pivot hinge 24. In some embodiments, the cross-sectional area 48 of the base attachment member 38 can be slightly smaller than the inner surface 50 of the attachment device attachment member 40. Therefore, as shown, the base attachment member 38 can be slid into the attachment device attachment member 40. Then, the base attachment member 38 can support the attachment device 14 by fixing the attachment device attachment member 40 within the base attachment member 38, as shown.

[0040] In some embodiments, the attachment device attachment member 40 may include a hollow portion having a larger cross-section 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 guardrail 46 includes an attachment device attachment member 40 configured to receive the base attachment member 38.

[0041] In some embodiments, the base attachment member 38 may include a base locking mechanism 42 for interacting with the attachment locking mechanism 44 to lock the attachment 14 in place 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 sleeve for receiving the base locking mechanism 42, and in some embodiments, the base locking mechanism may be a spring loaded ball or shaft. 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 to lock the attachment device 14 in place. Similarly, to remove the attachment device 14 from the base 12 , the user may depress the base locking mechanism 42 , pulling the attachment device 14 away from the base 12 , sliding the attachment device attachment member 40 off the base attachment member 38 .

[0042] In some embodiments, the base attachment member 38 may be an extension of the front leg 18. Thus, the angle of the attachment relative to the floor may be based on the angle 26. For example, Figure 2As shown, the greater the angle 26, the more inclined the front leg 18 is, and therefore the more inclined the guardrail 46 is. Since the attachment device 14 is attached to the front leg 18, and the front leg 18 needs to support the minimum angle of the attachment device 14 and the user, the angle of the attachment device 14 relative to the ground can be based on the angle 26. The relative inclination of the attachment device 14 based on the angle 26 will be discussed in more detail below.

[0043] In some embodiments, the base attachment member 38 can be hollow and receive the attachment device attachment member 40 therein. The attachment locking mechanism 44 can protrude from the attachment device attachment member 40 by a spring pushing the protrusion. The base locking mechanism 42 can be a hole that is configured to receive the protruding attachment locking mechanism 44. The user can slide the device attachment member 40 into the hollow portion of the base attachment member 38. When the attachment locking mechanism 44 is moved onto the base locking mechanism 42 (hole), the attachment locking mechanism 44 can extend into the base locking mechanism 42 to attach the attachment device 14 (e.g. Figure 2 The user can remove the attachment device 14 from the hollow portion of the base attachment member 38 by simply depressing the attachment locking mechanism, thereby compressing the internal spring.

[0044] Figure 3 The base 12 is shown in a chair configuration, which includes a backrest 52 and a platform 36 to provide a seat for a user. In some embodiments, the platform 36 can be attached to the front leg 18 so that the platform 36 can act as a seat, providing a sitting surface or a standing surface that is substantially parallel to the floor / ground or surface on which the base 12 is located. In some embodiments, the attachment site 22 is inclined relative to the front leg 18 so that the attachment site 22 provides a groove that is substantially parallel to the floor and is disposed on the inner side of the front leg 18. When the base 12 is fully opened to the standing configuration (e.g., the angle 26 is maximum), the attachment site 22 can provide a groove that is parallel to the floor on which the convertible platform 10 is located. Therefore, the platform 36 can be substantially parallel to the floor. The platform 36 can provide a seat, a step, a shelf, or any platform for users and / or objects. Therefore, the attachment device 14 can be in an inclined position based on the angle 26 and similarly based on the angle of the front leg 18 with the floor. Each attachment device 14 may be designed to provide an angle sufficient for user comfort depending on the configuration of the convertible platform 10 in which the attachment device 12 is incorporated.

[0045] Figure 3An exemplary backrest 52 is shown. The backrest 52 can be attached to the base attachment member 38 at the attachment device attachment member 40. Here, the hollow cross-section of the attachment device attachment member 40 is slightly larger than the outer surface of the base attachment member 38. Therefore, the attachment device attachment member 40 can receive the base attachment member 38. Any of the base locking mechanisms 42 and attachment member locking mechanisms 44 described above can be used to lock the backrest 52 to the base 12. The backrest 52 can be designed to provide a reclining support for a user sitting on the platform 38 while taking into account the angle 26. The backrest portion 54 of the backrest 52 can be substantially aligned with the front leg portion 18, or it can be slightly tilted forward or backward to provide a comfortable reclining sitting posture. In addition, the backrest portion 54 can be concave and include soft materials to provide a comfortable posture for the user.

[0046] As shown, the base attachment member 38 is a direct linear extension of the front leg 18. However, the base attachment member 38 can be angled relative to the front leg 18 to provide an angle for the attachment device 14. The base attachment member 38 can be tilted relative to the front leg 18 to provide a comfortable angle for the attachment device 14 so that, for example, the high chair 16 provides a flat or slightly tilted seating surface and a tilted backrest, the side rails 46 are horizontal, the backrest 52 is tilted, etc.

[0047] In some embodiments, the steps 34 and platforms 36 can be selectively attached to the front legs 18 and rear legs 20 at the attachment locations 22. As described above, the attachment locations 22 can provide a flat recess (parallel to the floor) for receiving and supporting the steps 34 and / or platforms 36. The attachment locations 22 can be angled relative to the front legs 18 based on the angle 26 to provide the steps 34 and platforms 36 that are substantially parallel to the floor. This allows the user to Figure 3 The chair configuration shown climbs up and sits on the platform 36. In this exemplary embodiment, the user can be of any age and size. The steps 34 and platform 36 can be set to any height depending on the size of the user, or can be set to provide a shelf for objects. Thus, the convertible platform 10 can provide seating for users of any age, size, and shape. The backrest 52 can be plastic, wood, fabric, rubber, foam, or any combination of materials.

[0048] Figures 4A-4C An exemplary guardrail 46 is shown for attachment to the base 12 . Figure 4AThe guardrail 46 is shown extending approximately 180 degrees around a user supported on the platform 36. In some embodiments, the guardrail 46 provides a support for a child standing on the platform 36 to hold on to. The child can use the steps 34 to climb onto the platform 36 and hold on to the guardrail 46 for support while standing. The first end 56 of the guardrail 46 can be attached to a first base attachment member 58, and the second end 60 of the guardrail 46 can be attached to a second base attachment member 62, and the guardrails can be continuous to provide a single 180 degree support guardrail 46. In some embodiments, such as Figure 4A As shown, the guardrail 46 covers approximately 180 degrees; in some embodiments, such as Figure 4B As shown, the guardrail 46 covers substantially 360 degrees around the child.

[0049] Figure 4B The platform 36 is shown connected to the front leg 18 and the rear leg 20 at the front attachment site 22a and the rear attachment site 22b. In certain embodiments, the platform 36 can be configured to be coupled to the front leg 18 or the rear leg 20, or to the front leg 18 and the rear leg 20. The platform 36 can slide into the attachment site 22 and be held in place based on friction, or the platform attachment 37 can hold the platform 36 in place.

[0050] In some embodiments, the platform 36 may include a platform attachment 37. The platform attachment 37 may be spring loaded to lock the platform 36 onto the front attachment site 22a and the rear attachment site 22b. The platform attachment 37 may be a small protrusion that may be pressed into one side of the platform 36 when pressed in by hand or by sliding the platform 36 into place. For example, the platform attachment 37 may be configured at an angle so that when the platform 36 is slid into a locked position between the front legs 18 and the rear legs 20, the sharp angle on the platform attachment creates a force on the rear legs to compress the internal spring and press the platform attachment 37. In addition, the side of the platform attachment 37 that contacts the rear legs 20 may be configured at an angle close to 90 degrees so as not to allow the platform attachment 37 to press when pressed against the rear legs 20. The user may press the platform attachment 37 by hand to slide the platform 36 out and remove the platform 36 from between the legs. This locks the platform 36 in place between the front legs 18 and the rear legs 20 to prevent accidental movement of the platform 36. Similarly or alternatively, a platform attachment 37 may be provided adjacent the front legs 18, which functions as described above in relation to the rear legs 20.

[0051] Figure 4COne embodiment of a guardrail 46 is shown that provides substantially 360 degrees of support. As shown, the guardrail 46 can provide 360 ​​degrees of continuous support around the user. In addition, in some embodiments, one side of the guardrail 46 can provide a door and hinge (not shown) that can be opened and securely closed to provide a passage or entrance for the user. The door and hinge can be securely locked so that a child can use the guardrail 46 without accidentally opening the door.

[0052] In certain embodiments, Figure 4B Any portion of the platform 36 shown in any other figure described herein can be added or combined with the platform 36 shown in any other figure described herein. In some embodiments, the platform 36 includes a lip 64. The lip 64 can be a raised portion near the edge of the platform 36 to provide tactile feedback to the user when the user stands. The user can stand on the platform 36 and feel the lip 64 with his feet. The lip 64 can provide tactile feedback to the user so that the user knows the location of the edge of the platform 36 and avoids stepping on the edge without stepping on it.

[0053] In addition, the platform 36 may include a drip tray 66 and / or a channel (not shown) for catching spills. For example, if a child standing on the platform 36 spills liquid, the liquid may be collected in the drip tray 66 or the channel away from the child's feet. The drip tray 66 may be disposed below the top surface 68 of the platform 36. The drip tray 66 can be easily removed, dumped, and cleaned. In some embodiments, a hole 70 may be provided on the top surface 68 of the platform 36 for receiving any spilled liquid and transferring it to the drip tray 66 to keep the top surface 68 dry and convenient for children to use. In some embodiments, the top surface 68 of the platform 36 and / or the steps 34 include a step surface to provide a high friction surface for children to stand on. The high friction surface can provide grip for the child's feet or shoes, so that when the platform 36 is slippery, the child will not easily slip on the platform 36.

[0054] In some embodiments, the guardrail 46 can be attached to the base 12 via the base attachment member 38 and the attachment device attachment member 40, as described above. In addition, the base attachment member 38 and the attachment device attachment member 40 can provide an adjustable height guardrail 46 for children of different heights. As described above, a plurality of locking mechanisms can be provided on the base attachment member 38 and the attachment device attachment member 40 to adjust the height of the attachment device 14.

[0055] Figure 5AOne embodiment of a high chair 16 for supporting a child in a seated position is shown. In some embodiments, the high chair 16 can be selectively attached to the base 12 by the interaction of the attachment device attachment member 40 with the base attachment member 38, as described above. In some embodiments, the attachment device attachment member 40 can be slightly larger than the base attachment member 38 so as to receive the base attachment member 38 in a telescopic manner. In some embodiments, the high chair 16 can include a concave seat 74 for receiving a child. The concave seat 74 can be U-shaped so as to provide free movement of the child's legs. The U-shape of the concave seat 74 can provide an unobstructed free movement area for the child's legs while ensuring the safety of the child through the straps (not shown). The straps can be set between the child's legs or wrapped around the child's waist and connected to the high chair 16 to secure the child.
