TECHNICAL FIELD
This application relates generally to gate latches and, in particular, to an adjustable gate latch assembly adapted for use with either left side hinge locations or right side hinge locations.
BACKGROUND
FIGS. 1A and 1B show an exemplary prior art gate latch assembly 1 installed on a door 2, between two posts 3a and 3b, where rotation of a handle 4a in direction 4b (or handle 4c in direction 4d) causes rotation of a latch bar 5 in direction 6. In the illustrated position, door hinges 2d would be toward the left side of the image of FIG. 1A and to post 3b, with hinge plates mounted on the face 2a of the door. The gate latch assembly 1 includes a front part 1a mounted on door face 2a and which carries the latch bar 5, and a back part 1b mounted. on door face 2b. The latch bar 5 is seated in a slot of a gate latch plate 7 that is mounted to gate post 3a. Movement of the latch bar 5 in direction 6 moves the latch bar up out of the slot to enable the door to swing inward in image of FIG. 1A. Notably, such prior art gate latches are only capable of rotation of the latch bar 5 in the single direction 6. Thus, if the hinges are shifted to the right hand side of the door 2, the hinges must be installed at the opposite face 2b of the door and the gate latch assembly installed with front part 1a on face 2b and back part mounted on face 2a, per FIGS. 2A and 2B. In this orientation, the door would swing open in a direction to an opposite side of the fence line than that of the FIGS. 1A and 1B. Thus, in the prior art gate latch assembly, the swing open direction is defined by hinge location, and is not selectable. In order to provide user flexibility, manufacturer's provide two different gate latch assemblies (e.g., a right side latch and a left side latch).
It would be desirable to provide a gate latch assembly that provides greater flexibility in terms of swing direction, regardless of whether the door the hinges are located on the right side of the door or left side or the door.
SUMMARY
In one aspect, a gate latch assembly includes a door mountable portion including a body and carrying a pivotable latch bar that extends outward from a side of the body, and a handle part operatively connected to effect pivot of the latch bar when the handle is rotated. The door mountable portion includes a position limiting structure that is selectively positionable in a first location on the body or a second location on the body. When the position limiting structure is in the first location, the position limiting structure prevents the latch bar from pivoting in a first direction while permitting the latch bar to pivot in a second direction that is opposite the first direction. When the position limiting structure is in the second location, the position limiting structure prevents the latch bar from pivoting in the second direction while permitting the latch bar to pivot in the first direction.
In another aspect, a gate latch assembly includes a first door mountable portion including a first body and carrying a pivotable latch bar that extends outward from a side of the first body, and a first handle part operatively connected to effect pivot of the latch bar when the first handle is rotated. A second door mountable portion includes a second body and carrying a pivot bar, and a second handle part operatively connected to effect pivot of the pivot bar when the second handle is rotated. A shaft assembly is provided for interconnecting the first door mountable portion and the second door mountable portion through a hole in a gate door. The gate latch assembly includes one or more position adjustable components for permitting the gate latch assembly to be assembled in either a first configuration or a second configuration. In the first configuration, each of the latch bar and the pivot bar is rotatable away from its neutral position in only a first direction, in the second configuration, each of the latch bar and the pivot bar is rotatable away from its neutral position in only a second direction that is opposite the first direction.

DETAILED DESCRIPTION
Referring to FIGS. 3A and 3B, two door mountable portions 10a and 10b of a gate latch assembly are shown in front view (e.g., views from the side that will face away from the door surfaces). Each portion includes a respective body 12a and 12b with an associated handle 14a and 14b. Body 12a also carries the latch bar 16a of the assembly, with the latch bar 16a extending outwardly from a side 18a of the body 112a. As shown, the bodies include openings for receiving listeners to secure each body to respective, opposite faces of a gate door when the assembly is installed for use.
FIGS. 4A and 4B show side views, and FIGS. 5A and 5B show rear views with body recesses 30a and 30b. Per FIG. 4B, the latch bar slot 20a on side 18a of the body 12a extends both above and below the illustrated neutral position of the latch bar 16a. A blocking part 22a is located below the latch bar in order to prevent the latch bar from rotating in the downward direction (in the FIG. 5b view). Per FIG. 4A, a slot 20b on the side of body 12b is also provided and the body 12b carries a pivot bar 16b. A blocking part 22b is positioned to prevent the latch bar from rotating in the up direction (in the FIG. 5A view). Notably, when the two portions 10a and 10b are connected at opposite faces of a door, the blocking parts 22a and 22b would align with each other at opposite sides of the door, such that the blocking parts 22a and 22b work in the same manner in terms of limiting latch bar rotation in one direction. Notably, both blockings, parts can be selectively relocated from the illustrated positions of FIGS. 5B and 5A to positions on the opposite side of the latch bar 16a and pivot bar 16b (e.g., positions 23a and 23b) to switch the permitted rotation direction of the latch bar 16a and pivot bar 16b respectively.
In one implementation, each blocking part may be repositioned by removing a fastener that secures the blocking part in place, shifting the blocking part to the other location and securing in place with the same fastener. This could be achieved via access, removal and reposition of the blocking parts from the cavity side of each body or, in some embodiments, via the side slots 20a and 20b.
Notably, a dual acting spring 24a and 24b is provided on each portion 10a and 10b for biasing the latch bar 16a (and handle 14a) and the pivot bar 16b (and handle 14b), respectively, into their illustrated neutral positions. The dual acting springs 24a and 24b provide this function regardless of the position of the blocking parts 22a and 22b. The dual acting springs also provide this function if the blocking parts 22a and 22b are removed or left out entirely upon installation.
FIGS. 6A and 6B depict operation of portion 10a when the blocking part 22a is in the position of FIG. 5B. In this orientation portion 10a operates similar to the handle gate latch assembly portion 1a. FIGS. 7A and 7B depict operation of portion 10a when the blocking part 22a is switched to position 23a of FIG. 6B. Notably, the rotation direction of the latch bar in FIG. 7B is opposite that of the latch bar in FIG. 6B. The FIGS. 7A and 7B orientation provides two additional installation configurations for the inventive gate latch assembly, as compared to the prior art assembly 1. Thus, the inventive latch assembly, when in the orientation of FIGS. 6A and 6B can be mounted to a gate door 2 in either the manner as shown in FIGS. 1A-1B (door swings out of the page in the FIG. 1A view) or the manner shown in FIGS. 2A-2B (door swings out of the page in the FIG. 2A view). In addition, the inventive latch assembly, when in the orientation of FIGS. 7A and 7B, can be mounted to the gate door 2 in either the orientation shown in FIGS. 8A and 8B (door swings out of the page in the FIG. 8A view) or the manner shown in FIGS. 9A and 9B (door swings out of the page in the FIG. 9A view).
Referring now to FIGS. 10-16, a detailed exemplary configuration of the gate latch assembly 10 is shown. FIGS. 10-11 show the gate latch assembly with door mountable portions 10a and 10b in the configuration adapted for gate door installations of the type shown in FIGS. 1A-1B and 2A-2B, with the two portions in their respective opposed positions on opposite faces of a door (not shown). The illustrated shaft assembly 30 interconnects the two portions 10a and 10b, where the shaft assembly would extend through a hole in the gate door to make the interconnection. The shaft assembly 30 causes the two portions to operate together. Thus, rotation of handle 14a causes rotation of each of latch bar 16a, shaft assembly 30, pivot bar 16b and handle 14b. Likewise, rotation of handle 14b causes rotation of each of pivot bar 16b, shaft assembly 30, latch bar 16a and handle 14a. Here, each blockings, part 22a and 22b is mounted on a respective bracket 32a and 32b which is secured to its respective body 10a and 10b by one or more fasteners 34a and 34b. The brackets 32a and 32b span across the latch bar 16a and the pivot bar 16b, respectively. The blocking parts 22a and 22b are secured to the respective brackets by fasteners, such as fastener 36b.
Notably, each bracket 32a and 32b includes two respective mount locations for the blocking part, the illustrated position and another position 23a and 23b. If each blocking part 22a and 22b is moved to its second position 23a and 23b, the result is the configuration shown in FIGS. 12-13, which sets up the gate latch assembly 10 for installations of the type shown in FIGS. 8A-8B and 9A-9B. Thus, the gate latch assembly 10 provides a configuration in which a user can, relatively easily, adjust the configuration of the gate latch assembly to match the user's desired installation orientation and corresponding swing direction for a gate door.
In addition to adjustment of the gate latch assembly configuration by repositioning of the blocking parts 22a and 22b on their respective brackets 32a and 32b, the configuration can also be adjusted by switching the brackets 32a and 32b between the two bodies 12a and 12. Referencing FIGS. 14 and 15, this adjustment is akin to rotating the position of the brackets 32a and 32b in the gate latch assembly, per arrows 50, but without rotating the position of any other parts of the gate latch assembly.
FIGS. 16A-16B show operation of portion 10a in both of its configurations, as viewed from the back side or door facing side.
In the inventive gate latch assembly, there is no need to provide both a left side latch assembly and a right side latch assembly. Instead, the adjustable configuration of the inventive latch assembly accommodates both left side installation and right side installation, which can be adjusted per consumer need. In addition, this unique latch design will allow the door to be opened inward or outward with flexibility of the door hinge orientation.
It is to be clearly understood that the above description is intended by way of illustration and example only, is not intended to be taken by way of limitation, and that other changes and modifications are possible. The scope of protection of each following claim shall only be limited by features expressly set forth in such claim.
