Abstract
A traffic gate apparatus comprises an upstanding pedestal. A first elongate arm is also provided having a proximal end and a distal end, with the proximal end of the first elongate arm being pivotally connected to the pedestal at a first pivot axis. A second elongate arm has a proximal end and a distal end, with the proximal end of the lower elongate arm being pivotally connected to the pedestal at a second pivot axis. The second pivot axis is below the first pivot axis such that the first and second elongate arms are movable between a lowered position, in which the first and second elongate arms are generally horizontal and parallel with the first elongate arm being above said second elongate arm, and a raised position. The first and second elongate arms each have an adjustment mechanism such that a length thereof can be varied.
Claims24
A traffic gate apparatus comprising:
- an upstanding pedestal;
- a first elongate arm having a proximal end and a distal end, said proximal end of said first elongate arm being pivotally connected to said pedestal at a first pivot axis;
- a second elongate arm having a proximal end and a distal end, said proximal end of said second elongate arm being pivotally connected to said pedestal at a second pivot axis, said second pivot axis being below said first pivot axis;
- said first and second elongate arms being movable between a lowered position in which said first and second elongate arms are generally horizontal and parallel with said first elongate arm being above said second elongate arm, and a raised position;
- and
- said first and second elongate arms each having an adjustment mechanism such that a length thereof can be varied,
- wherein each of said first and second elongated arms are pivotally connected to said pedestal via corresponding first and second hinges, each of said hinges including an outer tubular element and an inner tubular element, said outer tubular element being fixed with respect to said pedestal and at least a portion of said inner tubular element being rotatable with respect to said outer tubular element,
- wherein said inner tubular element has an end portion that extends beyond said outer tubular element, a corresponding one of said first and second elongate arms being attached to said end portion, and
- wherein at least one of said inner tubular elements has a linkage connecting structure for allowing motorized operation.
A traffic gate apparatus as set forth in claim in 4, wherein said arm elements and said extendible portions are telescopically connected.
A traffic gate apparatus comprising:
- an upstanding pedestal;
- a first elongate arm having parallel first and second arm elements;
- a first hinge at which proximal ends of said first and second arm elements are pivotally connected to said upstanding pedestal so as to pivot about a horizontal pivot axis;
- said first hinge including an outer tubular element and an inner tubular element, said outer tubular element being fixed with respect to said pedestal;
- said inner tubular element having first and second end portions extending beyond said outer tubular element, said first and second arm elements being attached to said first and second end portions of said inner tubular element;
- and
- said inner tubular element further having a central portion fixed with respect to said outer tubular element, said central portion being separated from said first and second end portions by respective cuts such that said inner tubular element forms a torsion spring,
- wherein said inner tubular element of said first hinge has a linkage connecting structure for allowing motorized operation.
