Self-clamping ladder caddy

A self-clamping caddy for attachment to a ladder upright having first and second parallel, horizontally spaced, vertically extending surfaces, said caddy comprising:

• an open tray having a bottom and at least first and second spaced side walls,
• handle means including a pair of spaced handles, each handle extending between a first and second sidewall and arranged to support the tray from above so that the bottom is substantially level, said handles being pivotably connected to the sidewalls to fold down and not obstruct the contents of the tray,
• first gripping means attached to the tray near the bottom thereof comprising a first friction member facing outwardly from a sidewall of the tray,
• second gripping means comprising a bracket attached to the tray, an arm attached to the bracket, and a second friction member attached to the arm and disposed higher than the first friction strip and facing inwardly toward said sidewall with the second friction member spaced a greater distance from the sidewall than the first friction member,
• means for adjusting the spacing in a horizontal direction between the first and second friction members, and
• means for clamping the adjusting means when said first and second friction members are spaced apart in a horizontal direction slightly greater than the respective horizontally spaced vertical surfaces, such that the weight of the tray causes the first and second friction members to engage the respective first and second vertical surfaces when the tray is not supported by the handle means, but which are disengaged when the tray is supported by the handle means.
