Abstract
An improved releasable gate locking device for preventing the opening thereof by animals. The device is used with a gate and fence structure and comprises a locking pin which includes a head portion having upper and lower walls spaced apart along the pin's axis so as to define a groove therebetween. The lower wall is at right angles to the pin's axis and the upper wall is inclined away from the pin's axis. The pin cooperates with two spaced apart plates having aligned holes for receipt of the pin and the pin will swivel if not raised in a vertical direction. The lower wall prevents the pin from being withdrawn since swiveling of the pin causes the lower wall to engage the lower plate. The upper inclined wall serves to guide the pin back into proper position when a lifting force on the pin is released.
Claims3
In combination an animal head gate and frame assembly wherein the head gate is hingedly supported on hinges secured to the frame and cooperating formations on the edge of the head gate remote from the hinges and the adjacent portion of the frame, the formations being adapted to receive a locking pin having an axis and upper and lower regions said pin having support means for supporting said pin on said formation on the adjacent portions of said frame, said support means being positioned in the upper region of said pin, said pin having a head end at the lower region of said pin, said head end comprising a first and second wall means vertically spaced apart along the axis of said pin for defining a groove therebetween, said hinges secured to said frame comprising vertically spaced apart plates each having means defining a hole therein for receiving said pin, said groove being slightly wider than the distance said plates are spaced apart, said first wall means being formed at right angles to the axis of said pin, said second wall means being positioned between said first wall means and said support means and at an angle with the axis of said pin so that said second wall means diverges away from said first wall means.
