Abstract

A convertible platform for supporting a user in a standing or seated position is presented. In some embodiments, the convertible platform presents a set of front legs and a set of back legs that pivot about a pivot hinge to a preferred angle. The set of front legs and the set of back legs provide a base for supporting various attachment devices. The various attachment devices may comprise attachment members for attaching to base members for supporting the attachment device. The various attachment devices may be configured for supporting infants, toddlers, children, and adults in both standing and sitting positions. Furthermore, various attachments may be connected between the sets of legs for providing steps, platforms, shelves, and seats for the various users and/or objects.

First claim

Having thus described various embodiments of the disclosure, what is claimed as new and desired to be protected by Letters Patent includes the following:

1 . A convertible platform for supporting a user in a seated position or a standing position, the convertible platform comprising:
a base comprising:
a set of front legs and a set of back legs,
wherein the set of front legs comprise a distal end proximate a surface supporting the convertible platform and a proximal end opposite the distal end;
attachment points disposed on each front leg of the set of front legs at the proximal end;
a platform attached to each front leg of the set of front legs at the attachment points,
wherein the platform comprises a spring-loaded protrusion interacting with the set of front legs and/or the set of back legs for locking the platform in place;

a pivot hinge connecting the set of front legs and the set of back legs and providing rotation of the set of front legs relative to the set of back legs; and
base attachment members,
wherein the base attachment members are an extension of the set of front legs at the proximal end; and
an attachment device for attaching to the base and supporting the user, the attachment device comprising attachment device attachment members configured to attach to the base attachment members, wherein the attachment device is configured to support the user in a standing or sitting position.

2 . The convertible platform of claim 1 ,
wherein the base attachment members are hollow and receive the attachment device attachment members; and further comprising a set of attachment locking mechanisms and a set of base locking mechanisms configured to lock the attachment device on the base.

3 . The convertible platform of claim 1 , wherein the attachment device is a highchair.

4 . The convertible platform of claim 3 , wherein the highchair comprises:
a U-shaped seat and sidewalls for securing a child in the highchair; an adjustable backrest for adjusting based on a height of the child; and a selectively attachable tray configured to attach to the sidewalls.

5 . The convertible platform of claim 1 , wherein the attachment device is a guard rail and is attached at a height for gripping by a child when the child is standing on the platform.

6 . The convertible platform of claim 5 , wherein the guard rail provides 180-degree support around the child.

7 . The convertible platform of claim 1 , wherein the attachment device is a backrest, and the platform provides a seat that is substantially parallel with the surface.

8 . The convertible platform of claim 1 ,
wherein the attachment device is disposed in a reclined position based on a first angle between the set of front legs and the set of back legs, and wherein the first angle provides a second angle of the base attachment members relative to the surface.

9 . The convertible platform of claim 1 , wherein the set of front legs rotate relative to the set of back legs to provide a folded configuration of the base for storage.

10 . A convertible platform for supporting a user in a seated position or a standing position, the convertible platform comprising:
a base comprising:
a set of front legs and a set of back legs,
wherein the set of front legs comprise a distal end proximate a surface supporting the convertible platform and a proximal end opposite the distal end;
attachment points disposed on an inner side of each front leg of the set of front legs;
a platform attached to each front leg of the set of front legs at the attachment points,
wherein the platform comprises a spring-loaded protrusion interacting with the set of front legs and/or the set of back legs for locking the platform in place;

a pivot hinge connecting the set of front legs and the set of back legs and providing rotation of the set of front legs relative to the set of back legs; and
base attachment members,
wherein the base attachment members are a linear extension of the set of front legs at the proximal end;
an attachment device for attaching to the base and supporting the user, the attachment device comprising attachment device attachment members configured to attach to the base attachment members, wherein the attachment device is configured to support the user in a standing or sitting position.

11 . The convertible platform of claim 10 ,
wherein the base attachment members are hollow and receive the attachment device attachment members; and further comprising:
a set of attachment locking mechanisms and a set of base locking mechanisms configured to lock the attachment device on the base.

12 . The convertible platform of claim 11 , wherein the set of attachment locking mechanisms is a set of spring-loaded pins and the set of base locking mechanisms is a set of holes configured to receive the set of spring-loaded pins.

13 . The convertible platform of claim 10 ,
wherein the attachment device is disposed in a reclined position based on a first angle between the set of front legs and the set of back legs, and wherein the first angle provides a second angle of the base attachment members relative to the surface.

14 . The convertible platform of claim 10 ,
wherein the attachment device is a guard rail and is attached at a height for gripping by a child when the child is standing on the platform, wherein the guard rail provides 360-degree support around the child.

15 . A convertible platform for supporting a user in a seated position or a standing position, the convertible platform comprising:
a base comprising:
a set of front legs and a set of back legs,
wherein the set of front legs comprises a distal end proximate a surface supporting the convertible platform and a proximal end opposite the distal end;
attachment points disposed on each front leg of the set of front legs;
a platform attached to each front leg of the set of front legs at the attachment points,
wherein the platform comprises a spring-loaded protrusion interacting with the set of front legs and/or the set of back legs for locking the platform in place;

a pivot hinge connecting the set of front legs and the set of back legs and providing rotation of the set of front legs relative to the set of back legs; and
base attachment members configured to receive an attachment device for supporting the user,
wherein the base attachment members are an extension of the set of front legs at the proximal end.

16 . The convertible platform of claim 15 ,
wherein the base attachment members are a linear extension of the set of front legs, wherein the attachment device is disposed in a reclined position based on a first angle between the set of front legs and the set of back legs, and wherein the first angle provides a second angle of the base attachment members relative to the surface.

17 . The convertible platform of claim 15 , wherein the platform is secured in the attachment points substantially parallel to the surface.

18 . The convertible platform of claim 15 , wherein the attachment points are a first set of attachment points and further comprising:
a second set of attachment points disposed in the set of front legs; and a step connected to the second set of attachment points.

19 . The convertible platform of claim 18 , wherein the step is U-shaped and invertible providing at least two platform heights between heights of the second set of attachment points.

20 . The convertible platform of claim 15 , wherein the set of front le
