The present invention relates to a gravity latch device comprising a latch assembly mounted to a fence post adjacent an opening or portal in a fence, wall or other barrier and a keeper assembly attached to a gate post of a gate movable between an open position and a closed position to close or block the opening or portal when the gate is closed.
The latch assembly comprises a latch actuator assembly disposed to selectively engage a pivotal latch member.
The latch actuator assembly comprises an upper actuator pull knob and an elongated interconnecting member including having a ivot latch engaging surface.
A keeper latch assembly pivotally supports the pivotal latch member including a striker pin recess to selectively receive a striker pin of the keeper assembly to maintain the gate in the closed position.
The pivotal latch member a knob to selectively engage the pivot latch engaging member to selectively control the movement and position of the striker pin.
A latch mount assembly and a striker pin mount assembly may include an arcuate or concave base having a radius of curvature equal to or less than the radius of the fence post and gate post respectively mounted to the fence post and the gate post.
The gravity latch device may further include a latch locking assembly to prevent unauthorized opening of the gate. In particular, the latch locking assembly comprises a first lock member or plate having a first lock receiving aperture extending outwardly therefrom and an upper hollow actuator pull knob shroud movable between a first or unlocked position and a second or locked position including a hollow sleeve having a second lock member or flange and a cap or top having a centrally disposed aperture formed therethrough to selectively receive the upper portion of the elongated interconnecting member of the latch actuator assembly when the upper hollow actuator pull knob shroud is in the first or lower position.
The gravity latch device is operable in at least two (2) configurations. The first closed or secured configuration is when the gate is securely closed with the latch assembly is in a first position, and the pivotal latch member and the striker pin are also in a first position with the striker pin disposed within the striker pin recess. The second open or released configuration is when the gate can be swung open with latch actuator assembly and moved from the first position to a second position the latch engaging member or surface engages the latch actuator surface of the inner latch member to rotate the pivotal latch member form the first or striker pin retaining position to the second position clearing the striker pin from the striker pin recess allowing the gate to be opened.
The latch securing assembly is operable in a first or unlocked configuration and a second or locked configuration.
When in the first or unlocked configuration, the upper hollow actuator pull knob shroud is in first or lower position such that the upper actuator pull knob extends or is disposed above the upper hollow actuator pull knob shroud so that the latch assembly may be pulled upward from the first to second position causing the latch engaging member or lower surface of the latch actuator to engage the latch actuator surface of the pivotal latch member rotating the pivotal latch member from the first to second position allowing the striker pin of the keeper assembly to clear the pivot latch member such that the gate can swing open.
When in the second or locked configuration, the upper hollow actuator pull knob shroud is in the second or upper position such that the upper actuator pull knob or member is disposed within the upper hollow actuator pull knob shroud to prevent access to the upper actuator pull knob or member. The first lock receiving aperture and the second lock aperture are axially aligned relative to each other to receive a pad lock or similar locking device to lock or secure the upper hollow actuator pull knob shroud in the second or upper position to maintain the latch locking assembly in the locked configuration.
Due to the size and shape of the latch mount assembly and the striker latch mount assembly, the gravity latch device can be mounted to fence posts and gate posts of various sizes and shapes without modifying the structure of the top pull gravity latch device or any of the structural components.
The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the invention will be indicated in the claims.
