Abstract

A collapsible seat having a human support position when in an assembled condition and a transportable condition. The collapsible seat includes a seating member and a base member that are both substantially identical wherein the seat member and the base member are removably interengaged by a telescopic pedestal. When in the assembled condition, the pedestal is in at least one extended position and a top end of the pedestal is rigidly connected to the seat member while the bottom end of the pedestal is rigidly connected to the base member. When in the transportable condition, the pedestal is in a retracted position and is separate from the seat member and the base member and can be stored between the seat member and the base member.

Claims

1. A collapsible seat having an assembled condition and a transportable condition, said seat comprising:

a seat member having an upper seating surface, a peripheral seat edge, and a lower side that includes a first connector;

a base member including a peripheral base edge and a bottom surface extending substantially to said peripheral base edge and an upper side that includes a second connector;

a telescopic pedestal including a top end, a bottom end, and slidably interengaged outer and inner members, said pedestal having a retracted position and at least one extended position;

said top end of said pedestal including first connection means for removable interengagement with said first connector and said bottom end of said pedestal including second connection means for removable interengagement with said second connector;

said first connector being connected to said first connection means, said second connector being connected to said second connection means and said pedestal being in said at least one extended position when said seat is in said assembled condition;

said peripheral edges of said seat member and said base member being adjacent one another, and said pedestal being in said retracted position separate from said first and second connectors, when said seat is in said transportable condition and said inner and outer members have circular cross-sections, said first and second connection means are external threads on said top and bottom ends, and said first and second connectors are internally threaded.

2. A collapsible seat having an assembled condition and a transportable condition, said seat comprising:

a seat member having an upper seating surface, a peripheral seat edge, and a lower side that includes a first connector;

a base member including a peripheral base edge and a bottom surface extending substantially to said peripheral base edge and an upper side that includes a second connector;

a telescopic pedestal including a top end, a bottom end, and slidably interengaged outer and inner members, said pedestal having a retracted position and at least one extended position;

said top end of said pedestal including first connection means for removable interengagement with said first connector and said bottom end of said pedestal including second connection means for removable interengagement with said second connector;

said first connector being connected to said first connection means, said second connector being connected to said second connection means and said pedestal being in said at least one extended position when said seat is in said assembled condition;

said peripheral edges of said seat member and said base member being adjacent one another, and said pedestal being in said retracted position separate from said first and second connectors, when said seat is in said transportable condition, at least one of said upper side and said lower side includes a retainer for said pedestal, and said pedestal is between said upper and said lower side and is held in place by said retainer when said seat is in said transportable condition, and said outer member has an outer diameter and at least one of said base members and said seat member includes a spacer between said upper and lower sides approximately equal to said outer diameter.

3. The seat of claim 2, wherein said seat member and said base member are circular, and each said seat edge and base edge is a peripheral flange, said inner and outer members have circular cross-sections, said first and second connection means are external threads on said top and bottom ends, and said first and second connectors are internally threaded.

4. The seat of claim 2, wherein said seat member and said base member are circular, and each said seat edge and base edge is a peripheral flange, and said seating surface includes a cushioned portion.

5. The seat of claim 4, wherein said cushion portion is foam rubber material.

6. The seat of claim 2, wherein said seat member and said base member are circular, each said seat edge and base edge is a peripheral flange, and said peripheral flanges extend toward one another, and said pedestal is held in place by said retainer and said peripheral flanges when in said transportable condition.

7. The seat of claim 6, wherein said outer member has an outer diameter and at least one of said base members and said seat member includes a spacer between said upper and lower sides approximately equal to said outer diameter.

8. A collapsible seat having an assembled condition and a transportable condition, said seat comprising:

a seat member having an upper seating surface, a peripheral seat edge and a lower side that includes a first connector;

a base member having an upper side that includes a second connector, a peripheral base edge, and a bottom surface extending substantially to said peripheral base edge;

a pedestal having a top end, a bottom end, a retracted position and at least one extended position, said top end of said pedestal including first connection means for removable interengagement with said first connector and said bottom end of said pedestal including second connection means for removable interengagement with said second connector;

said first connector being connected to said first connection means, said second connector being connected to said second connection means and said pedestal being in said at least one extended position when said seat is in said assembled condition;

said pedestal being in said retracted position and separate from said first and second connectors when said seat is in said transportable condition;

said pedestal is telescopic and includes an outer member and an inner member slidably engageable with said outer member; and

,

said inner and outer members have circular cross-sections, said first and second connection means are external threads, and said first and second connectors are internal threads.

9. The seat of claims 8, wherein said peripheral flanges extend toward one another and at least one of said upper and lower sides includes a retainer for said pedestal, said pedestal being held in place by said retainer and said peripheral flanges when in said transportable condition.

10. The seat of claim 9, wherein said outer member has an outer diameter and at least one of said base members and said seat member includes a spacer approximately equal to said outer diameter.

11. A collapsible seat having an assembled condition and a transportable condition, said seat comprising:

a seat member having an upper seating surface, a peripheral seat edge and a lower side that includes a first connector;

a base member having an upper side that includes a second connector, a peripheral base edge, and a bottom surface extending substantially to said peripheral base edge;
