Abstract
A frame (10) is disclosed having a top member (12) and a base member (14). A support member (16) having two ends (18, 20) is pivotally connected to the top member (12) at one end (18) and the base member (14) at the other end (20). The top member (12) and the base member (14) rotate about their respective pivot connections with the support member (16) to alternate the collapsible frame (10) between a closed position and an opened position.
Claims17
A free-standing frame for use on a surface comprising:
- a support member;
- a top member pivotally connected by a first pivot connection about a first end of the support member and having an inner surface and an opposed outer surface;
- and,
- a base member pivotally connected by a second pivot connection about a second end of the support member and having an inner surface and an opposed outer surface,
- both the top member and the base member to rotate about their respective pivot connections with the support member between an opened position and a closed position, such that in the opened position, the outer surface of the base member abutting the support member and the top member being supported above the base member, and in the closed position, the inner surface of the top member abutting the inner surface of the base member with the support member disposed therebetween.

A free-standing frame for use on a surface comprising:
- a support member;
- a top member pivotally connected by a first pivot connection about a first end of the support member and having an inner surface and an opposed outer surface;
- and,
- a base member pivotally connected by a second pivot connection about a second end of the support member and having an inner surface and an opposed outer surface,
- both the top member and the base member being adapted to rotate about their respective pivot connections with the support member between an opened position and a closed position, the top member rotating at least 180° and the base member rotating at least 270°,
- in the opened position, the outer surface of the base member abutting the support member and the top member being supported above the base member, and
- in the closed position, the inner surface of the top member abutting the inner surface of the base member,
- the top member further having a channel along an edge thereof for receiving the first end of the support member and permitting limited rotation of the support member relative to the top member and the first pivot connection being a first pivot pin passing through the support member adjacent the first end through the channel and into the top member adjacent the edge thereof,
- the base member further having a notch along an edge thereof for receiving the second end of the support member and permitting limited rotation of the support member relative to the base member and the second pivot connection is a second pivot pin passing through the support member adjacent the second end through the notch and into the base member adjacent the edge thereof,
- the inner surface of the base member having a recess therein for receiving the support member when the base member is in the closed position.
