  • Patent number: 4887854
    Abstract: A gate latch structure is provided for use with either right-handed or left-handed gates. The latch includes a symmetrical main frame and keeper. The main frame has a striker receiving opening with two opposite cam surfaces flaring outwardly into a "Vee". A retainer stub is fixed to the main frame at a mid location at the inner end of the opening. A substantially flat keeper having a longitudinal axis has two opposite symmetrical striker receiving notches positioned at one end. The other end is pivotally connected at only one point to the main frame. The keeper may be sprung over the stub. While on one side of the retainer stub the keeper is for right handed gate and when it is on the other side it is for a left-handed gate. There are no springs and the weight of the keeper bar causes it to close over the striker.
