发明名称 Mountable work platform for a ladder
摘要 The present invention relates to a mountable work platform for use on a ladder, comprising a long plate and a short plate. The long plate and the short plate each further comprise a plurality of plates, arranged in a row and connected by a connection bar and a clamp bar, where a stable assembly is attained by protrusions of the connection bar and the clamp bar holding depressions on the plates. The connection bars of the long plate and of the short plate together embrace a step of the ladder, and the clamp bars of the long plate and of the short plate each hold another step of the ladder in a grip. The long plate and the short plate are independently usable as a table on the ladder, when the ladder is folded.
