  • Patent number: 5588687
    Abstract: A device or kit for making a refrigerator door child proof is disclosed. The device comprises about four distinct parts: a segment of shock cord (lanyard), a spring clasp having a swivel eyelet butt end connected to one end of the shock cord, a first adhesive backed mounting plate with a loop for receiving the spring clasp (first mounting plate), another adhesive backed mounting plate for tethering the spring clasp to via the lanyard (second mounting plate). The first mounting plate is adhered to a refrigerator door. The second mounting plate having the spring clasp and lanyard mounted thereto is either adhered to a second refrigerator door or the side of the refrigerator. When the door is opened by a child the shock cord allows the door to only slightly be opened. The shock cord then springs back to its relaxed state quickly shutting the door. The spring clasp can be operated by an adult by one hand. The device can be disabled by leaving the spring clasp unhooked. The device can only deliberately be enabled.
