Abstract
A collapsible easel with three legs is provided. First ends of the three legs are attached at an apex. The legs are moveable with respect to one another about the apex. The legs are moveable between collapsed and opened positions. The legs are disposed substantially adjacent one another in the collapsed position. The second ends of the legs are spaced a distance away from each other in the opened position. The legs form an upright pyramidal configuration when in the opened position. The easel is supported by a collapsible reinforcing member joining two of the legs. The reinforcing member has first and second arms joined by a pivoting mechanism. The easel is also reinforced by a collapsible bracing assembly comprising alpha, beta, and gamma support members attached to the set of three legs.

- the first end of the beta support member is fixedly attached to the second attachment point of the first leg, wherein the first end of the beta support member is configured to pivot about the second attachment point of the first leg,
- the second end of the beta support member is slidably attached to a third leg in the set of three legs,
- whereby the beta support member is pivotable about the first end of the beta support member between a first beta support member position and a second beta support member position, and
- (iii) a gamma support member comprising a first end and a second end, wherein
- the first end of the gamma support member is slidably attached to the third leg,
- the second end of the gamma support member is fixedly attached to the second attachment point of the second leg, wherein the second end of the gamma support member is configured to pivot about the second attachment point of the second leg,
- whereby the third gamma member is pivotable about the second end of the gamma support member between a first gamma support member position and a second gamma support member position, wherein
- the second end of the beta support member and the first end of the gamma support member are attached to each other, and
- wherein the set of three legs, the reinforcing member, and the bracing assembly are configured so that
- when the three legs are in the collapsed position,
- the reinforcing member is in the first reinforcing member position,
- the alpha support member is in the first alpha support member position,
- the beta support member is in the first beta support member position, and
- the gamma support member is in the first gamma support member position, and
- when the three legs are in the opened position,
- the reinforcing member is in the second reinforcing member position,
- the alpha support member is in the second alpha support member position,
- the beta support member is in the second beta support member position, and
- the third gamma member is in the second gamma support member position.
A collapsible easel comprising:
