Abstract

Provided is an adjustable barrier having a central hinge having a cylindrical post and an axis of rotation; a first expandable section coupled to the cylindrical post of the central hinge by at least a first connector; and a second expandable section coupled to the cylindrical post of the central hinge by at least a second connector. At least one of the first and second expandable sections is configured to articulate around the axis of rotation of the central hinge forming an articulation angle between the first and second expandable sections.

Claims (30)

1. An adjustable barrier comprising:

an inner upright comprising a plurality of openings extending through a thickness of the inner upright that are spaced along a vertical length of the inner upright;

a cylindrical post;

at least a first connector comprising an inner connecting portion and an outer connecting portion, the inner connecting portion sized to receive the cylindrical post so as to rotate relative to the cylindrical post around an axis of rotation, and the outer connecting portion adapted to removably couple to the inner upright by engaging at least one opening of the plurality of openings;

an outer upright;

at least a first expandable section coupled to the inner upright on a first side and the outer upright on a second side, wherein the first expandable section further comprises a first multiplicity of slats extending between the inner upright and the outer upright, the first multiplicity of slats hingedly interconnected in a scissoring lattice-type structure configured to expand outward from a compact, collapsed narrow configuration to an expanded, wide configuration; and

a footing slideably coupled to a lower end region of the outer upright that is adjustable relative to the barrier.

2. The barrier of claim 1 , wherein the footing comprises a rod extending upwardly and configured to be received into a correspondingly-shaped receiver element near the lower end region of the outer upright.

3. The barrier of claim 1 , wherein the footing incorporates casters.

4. The barrier of claim 1 , further comprising at least one handle coupled to the outer upright and configured to be grasped.

5. The barrier of claim 1 , wherein the post incorporates a second footing coupled to a lower end of the post.

6. The barrier of claim 5 , wherein the second footing incorporates casters.

7. The barrier of claim 1 , further comprising a second expandable section coupled to a second inner upright, the second inner upright coupled to the post by at least a second connector comprising an outer connecting portion and an inner connecting portion, the outer connecting portion of the second connector adapted to couple to at least one opening of a plurality of openings spaced along a vertical length of the second inner upright, the inner connecting portion of the second connector sized to receive the cylindrical post.

8. The barrier of claim 7 , wherein both the first and second expandable sections are movably coupled to the post in order to articulate around the axis of rotation forming an articulation angle between the first and second expandable sections.

9. The barrier of claim 8 , wherein the articulation angle is between 0 degrees at which the first and second expandable sections is folded over completely against one another to about 180 degrees at which the first and second expandable sections are unfolded relative to one another and extend within a single vertical plane.

10. The barrier of claim 1 , wherein the inner connecting portion of the first connector comprises a tubular knuckle and the outer connecting portion of the first connector comprises a pair of opposing flanges extending laterally outward from the tubular knuckle, wherein the tubular knuckle has an inner diameter sized to receive an outer diameter of the post and the pair of opposing flanges are configured to couple to the inner upright.

11. The barrier of claim 10 , wherein, when the post extends through the inner diameter of the tubular knuckle, the inner upright is positioned between the pair of opposing flanges.

12. The barrier of claim 11 , wherein each of the pair of opposing flanges includes a first aperture, wherein the first aperture of the pair of opposing flanges is configured to align with any one of the plurality of openings.

13. The barrier of claim 12 , wherein when the first aperture of the pair of opposing flanges aligns with one opening of the plurality of openings on the inner upright a bore is formed that is configured to receive a coupling element.

14. The barrier of claim 13 , wherein the coupling element is removably received within the bore.

15. The barrier of claim 1 , further comprising a hinge lock attached to the barrier and slideable between a locked position and an unlocked position.

16. An adjustable barrier comprising:

an inner upright;

an outer upright;

a post coupled to the inner upright;

a first expandable section coupled to the post by at least a first connector on a first side and the outer upright on a second side, wherein the first expandable section further comprises a first multiplicity of slats extending between the inner upright and the outer upright, the first multiplicity of slats hingedly interconnected in a scissoring lattice-type structure configured to expand outward from a compact, collapsed narrow configuration to an expanded, wide configuration;

a second expandable section coupled to the post by at least a second connector forming a central hinge between the first expandable section and the second expandable section, the central hinge having an axis of rotation,

wherein the first connector and the second connector each comprises a tubular knuckle and a pair of opposing flanges extending laterally outward from the tubular knuckle, wherein the tubular knuckle has an inner diameter sized to receive an outer diameter of the post and the pair of opposing flanges are configured to couple to a respective one of the first and second expandable sections,

wherein, when the post extends through the inner diameter of the tubular knuckle, the inner upright of the respective expandable section is positioned between the pair of opposing flanges, wherein the inner upright of the respective expandable section comprises a plurality of openings extending through its thickness that are spaced along a vertical length of the inner upright; and

a footing slideably coupled to a lower end region of the outer upright, wherein the footing comprises a rod extending upwardly and configured to be received into a correspondingly-shaped receiver element near the lower end region of the outer upright.
