1. A device for growth acceleration and regeneration of lawn areas, comprising:
a housing defining an enclosed space which is open towards the bottom and can be placed on a lawn area and delimits a space above the lawn area, the housing comprising a frame formed of a plurality of struts arranged to form a first end wall, a second end wall, a first side wall, a second side wall and a roof; wherein said first and second end walls are each formed of two vertically and two horizontally extending struts, said first and second end walls longitudinally spaced from each other by said first and second sidewalls; wherein said first and second sidewalls are each formed of a plurality of longitudinally extending struts, each of said longitudinally extending struts connected to said first and second end wall, wherein said longitudinal struts are adjustable in length such that the distance between the first and second end walls may be varied, and each said longitudinal struts provided with blocking members to selectively lock said longitudinally extending struts; a film material covering said frame to define a tent, said film being formed so as to be transparent and gas-tight; an illumination device positioned within said housing for illuminating the lawn area, a CO2 outflow means being provided for introducing CO2 into the housing, wherein said housing is realized with moving equipment said moving equipment comprises a first pair of wheels coupled to said first end wall of the housing and a second pair of wheels coupled to said second end wall of the housing, a motor for driving one or more of said first pair of wheels, said first pair of wheels rotatable around a vertical axis by bearings, a brake connected to one or more of said second pair of wheels, said second pair of rotatable around a vertical axis by bearings,
a controller operatively connected with said blocking member, said motor and said brake;
said controller operable to automatically move said housing between an extended state and a collapsed state by releasing said blocking members, actuating said brake coupled to said second pair of wheels and actuating said motor coupled to said first pair of wheels, thereby preventing movement of the second wall of the housing while the length of the longitudinal struts are reduced and the first end wall moves toward the second end wallsaid controller operable to automatically move the entire housing in said extended state by locking said blocking members, releasing said brake coupled to said second pair of wheels and actuating said motor coupled to said first pair of wheels thereby automatically and freely moving said housing over an entire portion of the lawn area for growth acceleration and regeneration of the entire portion of the lawn area in sections. |
