This invention relates to oar, fork and U-shaped gate latches, and in particular to two part sleeves that fasten about existing arms of U-shaped gate latches, as well as bonded and slide on sleeve and cover devices, and replacement gate latches and methods for preventing injury with persons that come into contact with oar, fork and U-shape gate latches that are pivotally attached to fixed support posts next to an opening in a fence.
Popular gate latches for mesh fences will often use a pivotable oar, fork or U-shaped latches to lock and unlock a swinging gate which is used to open and close an opening in a mesh fence. One side of the gate is usually hingedly attached to a fixed support post. The free swinging edge post of the gate will swing into and out of the pivotable gate latch. See for example, U.S. Pat. No. 2,666,660 to Yougworth; U.S. Pat. No. 4,691,541 to McQuade Sr.; and U.S. Pat. No. 5,593,141 to Cain et al. A problem with these popular gate latches are their narrow and often sharp metal tips which become protruding hazards when the gates are left open.
When the gate is open, the metal tips of the oar, fork or U-shape latch is generally facing sideways in a horizontal direction where the prong arms of the latch are parallel to the ground. Even if the outer tips are rounded, in these horizontal positions, injury can easily occur to someone walking into the gate latch. The problem is further compounded on playgrounds and school yards where running children can go front first and/or back first into these protruding hazards causing skin lacerations and punctures. Small children also have the danger of these protruding hazards being at face and eye level that can further cause serious harm.
Various attempts have been tried over the years to fix the problem. For example, wrapping electrical type tape around the latches is only a temporary fix, since the tape would unwrap over time, and the tape would be an attractive nuisance for children who would want to pull the tape loose. Sticking an old tennis ball on the latch is also only a temporary fix, since the ball would easily fall off or be easily pulled off.
The inventor is not aware of any products and solutions to protect children and/or adults from being injured by the protruding hazards of these oar, fork and U-shape gate latches that are left in their horizontal and unlocked positions. Thus, the need exists for solutions to the above problems with the prior art.
A primary objective of the present invention is to provide bonded on sleeve and cover devices, and methods for preventing injury from using oar, fork and U-shape gate latches that are pivotally attached to fixed support post next to an opening in a fence.
A secondary objective of the present invention is to provide slide on sleeve and cover devices, and methods for preventing injury from using oar, fork and U-shape gate latches that are pivotally attached to fixed support post next to an opening in a fence.
A third objective of the present invention is to provide replacement gate latches and methods for preventing injury from using oar, fork and U-shape gate latches that are pivotally attached to fixed support post next to an opening in a fence.

Two Part Sleeves
Referring to
A right sleeve can include a first half sleeve 410 having a narrow stem portion 412, which expands outward along a convex curved sides to an enlarged rounded midportion 414, and tapers back along a convex curved sides to a tip end 416 that can have an outer convex curved edge and an internal concave insert opening 419. The first half sleeve 410 can have a generally flat bottom surface.
An elongated channel 415 can start from the stem end 412 and run in an elongated curve shape with an opposite closed end before the tip 416. On the top of the first half sleeve 410 can be a pair of enlarged indents 413, 417 having smaller diameter through holes in the bottom of the indents.
The right sleeve can include a second half sleeve 420 having a narrow stem portion 422, which expands outward along a convex curved sides to an enlarged rounded midportion 424, and tapers back along a convex curved sides to a tip end 426 that can have an outer convex curved edge and an internal concave insert opening 429. The second half sleeve 420 can have a generally flat top surface.
An elongated channel 425 can start from the stem end 422 and run in an elongated curve shape with an opposite closed end before the tip 426. On the top of the second half sleeve 420 can be a pair of threaded openings 423, 427.
The curved shaped openings 415, 425 in each of the half sleeves 410, 420, can each be larger than the width and/or height of each of the flange arms 110, 120.
To assemble the two part embodiment 400, the installer can position the first half sleeve 410 over and about the top of the right flange arm 120 so that the top edge of the right flange arm 120 fits into the elongated curved channel 415. Next, the installer can position the second half sleeve 420 over and about the bottom of the right flange arm 120 so that the bottom edge of the right flange arm 120 fits into the elongated curved channel 425. Next, the installer can pass the shaft ends of the screws 432, 434 into the indented portions 413, 417 and rotate the screws into the threaded openings 423, 427 in the second half sleeve 420 until both half sleeves 410, 420 abut one another. The indents 413, 417 allow for the heads on the fasteners 432, 434 to be below the outer surface of the half sleeve 410.
The left flange arm 110 can similarly be installed with the same half sleeves 410, 420, but reversing the location of the half sleeves, 410, 420. For the left flange arm 110, the first half sleeve 410 can be located underneath the left flange arm 110, and the second half sleeve 420 can be positioned over the top of the left flange arm 110, and the screws 432, 434 be used to similarly attach the half sleeves 410, 420 together.
To increase the locking of the half sleeves 410, 420 to the flange arms 110, 120, the installer can insert materials, such as but not limited to two part epoxy, caulk, glue, bonding agent, adhesive and/or expanding filling material into the curved channels 415, 425. These materials can be inserted into the curved channels 415, 425 before the half sleeves, 410, 420 are positioned on the flange arms 110, 120. Alternatively, these materials can be squeezed into the ends 412, 422 of the respective channels 415, 425 after the half sleeves 410, 420 are attached to the respective flange arms 110, 120.
Still furthermore, the channels 415, 425 can inwardly protruding wings, and/or inwardly protruding bumps or other inwardly protruding members to better cause a friction fit between the flange arms 110, 120 and the channels 415, 425 of the half sleeves 410, 420.
Referring to
Although the embodiment shows a pair of fasteners, 432, 434 being used to attach the first half sleeve 410, to the second half sleeve 420, the invention can be used with one fastener to attach the half sleeves 410, 420 together.
While the fasteners 432, 434 are described as being screws with threaded shafts, other types of fasteners, can be used such as but not limited to self tapping friction locking fasteners, and the like.
Although the heads on the fasteners 432, 434 are shown with indented hex heads, such as those used in restrooms and the like, the heads can be raised hex heads and the like.
The two part sleeves and be packaged as kits for to be used with an oar, fork or U-shape gate latch. The enlarged curved channels 415, 425 in the half sleeves 410, 420 can be large enough to fit over different sized right and left flange arms 110, 120 in different oar, fork or U-shape gate latches.
