Abstract:
A sectional gate assembly having an open position and a closed position comprising:a gate;an upper closing element and a lower closing element for closing up a gate assembly opening, said upper closing element being flexibly connected with said lower closing element, each said closing element having a first and a second opposite side and each having at least one guide arranged on each of said first and second opposite sides of said each said closing element, said lower closing element connected to said gate assembly at least closely adjacent to said first opposite side;a first and a second single track guide rail, said at least one guide adapted to move within said guide rail, said first and second guide rails each having a vertical section and a horizontal section connected with a curved portion;a weight-counterbalancer having a traction mechanism which engages at a first end on one of said closing elements, and at a second end on an energy accumulator allowing said lower closing element to move into said horizontal section;said weight-counterbalancer including a deflection roller for said traction mechanism arranged beneath said horizontal section so that said weight-counterbalancer exerts, by way of said traction mechanism a pulling force that acts generally horizontally on said lower closing element in said gate assembly open position, said pulling force acting generally vertically on said lower closing element in said gate assembly closed position; andmeans for swiveling an upper edge of said upper closing element out of alignment with said guide rails in said closed position including a pivoting lever attached to said upper closing element and having means for driving said upper closing element from a first position in said gate assembly open position into a second position in said gate assembly closed position and back to said first position.
