Abstract

A collapsible support includes at least one leg that can be stored in a cavity and at least one substantially smooth surface when assembled in a deployed condition. The collapsible support can also include at least one substantially smooth surface when assembled in a collapsed or stored condition. The collapsible support includes unique provisions for associating the legs with a base in both the collapsed condition and the deployed condition.

Claims

1. A collapsible support comprising:

a base including a first end and a second end,

the first end comprising a first side portion and the second end comprising a second side portion,

a cavity formed between the first side portion and the second side portion,

the first side portion having projecting members defining a slot,

the base defining a base hole adjacent to the slot,

the base having a projecting base tenon disposed adjacent to the base hole on a side of the base hole opposite the slot, and

the projecting base tenon and the base hole having a substantially similar size and shape; and

a first leg disposed within the cavity during a collapsed position,

the first leg including a lateral tenon disposed on an upper end of the first leg,

the lateral tenon and the slot having a substantially similar size and shape,

the first leg having a projecting leg tenon adjacent to the lateral tenon,

the first leg defining a leg hole disposed adjacent to the projecting leg tenon on a side of the projecting leg tenon opposite the lateral tenon, and

the projecting leg tenon being substantially similar in size and shape to the leg hole, the base hole, and the projecting base tenon.

2. The collapsible support according to claim 1, further comprising a second leg disposed within the cavity during a collapsed position,

the second side portion of the base having second projecting members defining a second slot,

the base defining a second base hole adjacent to the second slot,

the base having a second projecting base tenon disposed adjacent to the second base hole on a side of the second base hole opposite the second slot,

the second projecting base tenon and the second base hole having a substantially similar size and shape,

the second leg including a second lateral tenon disposed on an upper end of the second leg,

the second lateral tenon and the second slot having a substantially similar size and shape,

the second leg, having a second protecting leg, tenon adjacent to the second lateral tenon,

the second leg defining a second leg hole disposed adjacent to the second projecting leg tenon on a side of the second projecting leg tenon opposite the second lateral tenon, and

the second projecting leg tenon being substantially similar in size and shape to the second leg hole, the second base hole, and the second projecting base tenon.

3. The collapsible support according to claim 1, further comprising at least one substantially smooth surface while the collapsible support is in the collapsed position.

4. The collapsible support according to claim 1, wherein every exterior surface is substantially smooth while the collapsible support is in the collapsed position.

5. The collapsible support of claim 1, wherein, when the first leg is disposed within the cavity during a collapsed position, the lateral tenon is disposed in the slot and the projecting leg tenon is disposed in the base hole.

6. The collapsible support according to claim 1, wherein projecting leg tenon extends in a direction approximately normal to the lateral tenon of the first leg.

7. A collapsible support comprising:

a base comprising a first end and a second end

the base defining a base hole proximate to the first end,

the base having a projecting base tenon disposed adjacent to the base hole on a side of the base hole opposite the first end; and

a first leg having a first surface and a second surface,

the first leg having a lateral tenon extending from an upper end of the first leg,

the first leg having a projecting leg tenon adjacent to the lateral tenon,

the first leg defining a leg hole disposed adjacent to the projecting leg ten on a side of the projecting leg tenon opposite the lateral tenon,

wherein, in a collapsed position,

the first surface of the first leg faces the base,

the projecting leg tenon engages the base hole, and

the projecting base tenon engages the leg hole, and

wherein, in a deployed position,

the first surface of the first leg faces outward,

the lateral tenon engages the base hole, and the upper end of the first leg faces the base.

8. The collapsible support of claim 7, further comprising a second leg having a first surface and a second surface,

the base defining a second base hole proximate to the second end,

the base having a second projecting base tenon disposed adjacent to the second base hole on a side of the second base hole opposite the second end,

the second leg having a second lateral tenon extending from an upper end of the second the second leg having a second projecting leg tenon adjacent to the second lateral tenon,

the second leg defining a second leg hole disposed adjacent to the second projecting leg tenon on a side of the second projecting leg tenon opposite the second lateral tenon,

wherein, in a collapsed position,

the first surface of the second leg faces the base,

the second protecting leg tenon engages the second base hole, and

the second projecting base tenon engages the second leg hole, and

wherein, in a deployed position,

the first surface of the second leg faces outwards,

the second lateral tenon engages the second base hole, and

the upper end of the second leg faces the base.

9. The collapsible support of claim 8,

the second end comprising a second side portion,

the second side portion having projecting members defining a slot,

wherein, in the collapsed position, the second lateral tenon engages the slot, and

wherein, in the deployed position, the upper end of the second leg is received in a region disposed between the second projecting base tenon and the projecting members of the second side portion.

10. The collapsible support of claim 7, the projecting leg tenon being substantially similar in size and shape to the hole, the projecting base tenon being substantially similar in size and shape to the leg hole, and the lateral tenon being substantially similar in size and shape to the base hole.

11. The collapsible support of claim 7, the first end comprising a first side portion, the first portion having a projecting members defining a slot, and wherein, in a collapsed position, the lateral tenon engages the slot.

12. The collapsible support of claim 11, wherein, in the deployed position, the upper end of the first leg is received in a region disposed between the projecting base tenon and the projecting members of the first side portion.
