  • Plant bench for use in a greenhouse or nursery structure, and a greenhouse or nursery structure including the plant bench
    Patent number: 7051476
    Abstract: A plant bench device used in a greenhouse or nursery structure can reduce its horizontal width in order to create space for aisles in the structure. Two plant bench tables are supported by suitable support structure in the greenhouse or nursery structure. The tables are supported so as to be movable between a first position in which the two bench tables can be used for the greenhouse or nursery operations, and a second position in which the two plant bench tables are at least partially superposed. This allows more effective utilization of the available space in the greenhouse or nursery structure by creating aisles when the tables are moved to the second position.
