Claims8
Improved gate apparatus, comprising:
- a gate mounted pivotally for being pivoted in the forward direction to close said gate and for being pivoted in the rearward direction to open said gate;
- at least one coiled tension spring connected to said gate;
- first spring engaging means including at least one first curved surface for engaging said spring upon said gate being pivoted in said forward direction to place said spring in tension and to cause said spring to apply first tension force to said gate to cause said gate to be spring balanced in a generally horizontal closed position to close said gate;
- second spring engaging means including at least one second curved surface for engaging said spring upon said gate being pivoted in said rearward direction to place said spring in tension and to cause said spring to apply second tension produced force to said gate to cause said gate to be spring balanced in a generally vertical position to open said gate.
