DETAILED DESCRIPTION OF THE INVENTION

(14) As shown in FIGS. 1 through 3, the present invention relates to a gate latch assembly generally indicated as 10 to secure a gate (not shown) in a locked position to block or obstruct a portal in a fence or wall (not shown) allowing anyone of a number of users to independently unlock the gate latch assembly 10 and open the gate (not shown). In particular, the gate latch assembly 10 is selectively operable in a closed and locked position (FIG. 1) and an unlocked and open position (FIG. 2A).

(15) The gate latch assembly 10 comprises a latch frame generally indicated as 12 having a gate latch generally indicated as 14 pivotally coupled to the upper portion thereof and a lock tab support generally indicated as 16 (FIGS. 4 and 5) formed on the lower portion thereof to support a plurality of lock tabs each generally indicated as 18 on the latch frame 12.

(16) As best shown in FIGS. 3 through 5, the latch frame 12 comprises a pair of substantially flat, substantially parallel frame members each indicated as 20 held in fixed spaced relationship relative to each other by an interconnecting cross-member 22 extending between the upper portion of each substantially flat frame member 20. The lock tab support 16 may be formed on either or both the substantially flat frame members 20.

(17) The latch frame 12 is secured to a gate post 23 by an upper mount and lower mount. In particular as shown in FIGS. 1 through 5, the upper mount comprises a pair of upper serrated tabs each indicated as 24 extending inwardly from the upper portion of the interconnecting cross-member 22 and a pair of lower serrated tabs each indicated as 26 extending inwardly from the lower portion of the interconnecting cross-member 22 below the upper serrated tabs 24 to engage the outer face of the free end or post 23 of the gate (not shown) in combination with a U-bolt 28 extending through a pair of holes each indicated as 30 formed through the interconnecting cross-member 22 and held in place against the inner face of the free end or post 23 of the gate (not shown) by a pair of nuts or fasteners each indicated as 32. The lower mount comprises a mounting tab 34 extending downwardly from the inner or free end of each lock tab support 16 and substantially parallel to the corresponding substantially flat frame member 20. A hole 36 is formed through each mounting tab 34 to receive a carriage bolt 38 held in place against each side face of the free end or post 23 of the gate (not shown) by a nut or fastener 40.

(18) Although the substantially flat, substantially parallel members 20 of the latch frame 12 are depicted as substantially vertical; the substantially flat, substantially parallel members 20 of the latch frame 12 may be disposed in a substantially horizontal direction or on a diagonal direction relative to either a vertical or horizontal plain.

(19) As best shown in FIGS. 1 through 3, 6 and 7, the gate latch 14 comprises a pair of gate latch members each generally indicated as 42 held in fixed spaced relationship relative to each other by a gate latch cross-member 44. Each gate latch member 42 comprises a substantially flat proximal mounting plate or member 46 including a lower pivot hole 48 and an upper padlock receiving hole 50 formed therethrough, a substantially flat intermediate arm 52 off-set inwardly relative to the corresponding substantially flat proximal mounting plate or member 46 to selectively engage the fence or wall to limit horizontal movement of the gate (not shown) when the gate latch 14 is in the closed position and a substantially flat distal guide plate 54 angled outwardly from the distal end portion of the corresponding substantially flat intermediate arm 52 to guide the gate latch 14 from the open position to the closed position relative to the fence or wall (not shown) when the gate is closed (not shown).

(20) The gate latch 14 is pivotally coupled to the latch frame 12 by a pivot rod 56 extending through each lower pivot hole 48 formed on each substantially flat proximal mounting plate or member 46 and a hollow coupling sleeve 58 affixed to the outer surface of the interconnecting cross-member 22. A nut or fastener 60 secures the gate latch 14 to the latch frame 12 to limit horizontal movement therebetween.

(21) As best shown in FIGS. 8 and 9, each lock tab 18 comprises a pair of substantially flat, substantially parallel lock tab members or plates each indicated as 59 and an arcuate member or interconnecting end portion 60 to cooperatively form a frame member receiving channel 62 therebetween wide enough to operatively place each lock tabs 18 on the same substantially flat frame member 20. Specifically, the frame member receiving channel 62 is wider than the thickness of either substantially flat frame member 20. A substantially vertically disposed slot or oblong aperture 64 is formed on the free end portion of each lock tab member or plate 59 and aligned to relative to each other on each respective lock tab 18. The distance between the inner end of the frame member receiving channel 62 and the corresponding substantially vertically disposed slots or oblong apertures 64 is greater than the width of the latch frame member 20 on which the lock tabs 18 are mounted such that when a padlock 66 is operatively locked in a corresponding lock tab 18 to secure each lock tab 18 in place on the latch frame member 20 of the latch frame 12.

(22) When the gate latch assembly 10 is in the closed and locked configuration (FIG. 1), the aggregate height (AH) of the lock tabs 18 supported on the lock tab support 16 positions the upper most lock tab 18 adjacent to the proximal portion of the gate latch 14 to engage the gate latch 14 when rotated or pivoted upward to limit or stop rotation of the gate latch 14 to the open position (FIG. 2A).

(23) When one of the lock tabs 18 is unlocked, padlock 66 unlocked, and removed from the corresponding substantially vertically disposed or oblong aperture 64, the lock tab 18 can be removed from the substantially flat frame member 20 of the latch frame 12. Once the lock tab 18 is removed from the substantially flat frame member 20 of the latch frame a gap or space is created between the proximal end of the gate latch 14 and the upper most lock tab 18 allowing the gate latch 14 to pivot upward to clear the distal end of the gate latch 14 from the fence or wall (not shown) to swing open (FIG. 2A)

(24) FIG. 10 depicts a double drive gate latch assembly generally indicated as 10 that further comprises a keeper generally indicated as 70. Otherwise, similar structural elements are similarly designated.

(25) In particular, each substantially flat intermediate arm 52 rests in a corresponding channel 72 formed on opposite sides of the keeper 70 that is secured to the gate 71 by u-bolt 74 and fasteners or nuts 76, and bolt 78 and a nut fastener 80 combination opposite the gate post 23 on which the gate latch assembly 10 is secured.

(26) The keeper 70 used for double drive applications where two gates are used that meet in the middle of a gate opening or portal. The keeper 70 performs two functions. First, the gate frame is effectively widened. The second feature is that the keeper 70 retains or secures the two gates together. Ordinarily the gates tend to open as the two adjoining gate frame portions would separate when the gates are swung or pivoted. Since the arms are generally straight and have some tolerance, there is nothing to prevent the non-latch gate (not shown) from slipping out of the gate latches. The keeper 70 function is to retain or hold the gates (not shown) together. Furthermore, the substantially flat distal guide plates 54 disengage from the keeper 70 extending different as the keeper 70 has retaining elements on either side of each of the gate latch members 42 when the gate latch 14 is in the latched position.

(27) It will thus be seen that the objects set forth above, among those made apparent from the preceding description are efficiently attained and since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

(28) It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

(29) Now that the invention has been described,
