An automatic released foldable door, comprising:
- a first closing door means;
- a first door leaf connected to one side of said first closing door means, said first door leaf comprising a top edge, an outer edge vertically downwardly extended from one end of said top edge and a mounting hole vertically downwardly extended from said top edge;
- a first fixing device mounted at one side of said first door leaf;
- a micro switch mounted at said top edge and electrically connected to said first fixing device;
- a locking latch mounted in said mounting hole of said first door leaf;
- a second door leaf;
- a second fixing device mounted at one side of said second door leaf corresponding to said first fixing device and detachably connectable with said first fixing device;
- a third fixing device mounted at another side of said second door leaf;
- at least one first hinge having one hinge leaf thereof affixed to said first door leaf and another hinge leaf thereof affixed to said second door leaf;
- and
- a second closing door means having one end thereof connected to said first door leaf and another end thereof connected to said second door leaf,
- wherein said first fixing device comprises a lock hole, a control circuit and a power supply, said control circuit, said power supply and said lock hole being electrically coupled together, said second fixing device being lockable to and releasable by said lock hole subject to control of said control circuit.
An automatic released foldable door, comprising:
- a first closing door means;
- a first door leaf connected to one side of said first closing door means, said first door leaf comprising a top edge, an outer edge vertically downwardly extended from one end of said top edge and a mounting hole vertically downwardly extended from said top edge;
- a first fixing device mounted at one side of said first door leaf;
- a micro switch mounted at said top edge and electrically connected to said first fixing device;
- a locking latch mounted in said mounting hole of said first door leaf;
- a second door leaf;
- a second fixing device mounted at one side of said second door leaf corresponding to said first fixing device and detachably connectable with said first fixing device;
- a third fixing device mounted at another side of said second door leaf;
- at least one first hinge having a first hinge leaf thereof affixed to said first door leaf and a second hinge leaf thereof affixed to said second door leaf;
- and
- a second closing door means having one end thereof connected to said first door leaf and another end thereof connected to said second door leaf,
- wherein said locking latch comprises a touch pressure device, an elastic latch rod and a control knob, said touch pressure device comprising a receiving hole, said control knob being mounted at said outer edge of said first door leaf, said elastic latch rod being inserted into said mounting hole with one end thereof movable in and out of said receiving hole of said touch pressure device, said touch pressure device being mounted in a top side of said mounting hole to release said elastic latch rod for allowing said elastic latch rod to extend the said one end of said elastic latch rod out of said mounting hole, said control knob being operable by an external force to move said elastic latch rod into a retracted position where the said one end of said elastic latch rod is received inside said mounting hole.
