Abstract
A latch for a wire gate includes a frame defining a post confining enclosure. The frame is clamped to a fixed fence post in a substantially horizontal orientation. One of the sides of the frame is pivots about a substantially vertical axis. A spring biases the pivotally mounted side toward a closed position against the frame. A guide channel is provided for directing a movable fence post between the pivotally mounted side and the frame. The latch, as described above, enables a person to close a gate with one hand by pushing a movable fence post into the guide channel. As the post passes along the guide channel, the biasing force of the spring is overcome sufficiently to move the pivotally mounted side to an open position and allow entry of the post into the post confining enclosure.
Description
TITLE OF THE lNV~NLlON:
latch for a wire gate NAME OF lNV~NLOR:
Shane Walter Sroka FIELD OF THE lNV~-.llON
The present invention relates to a latch for a wire gate and, in particular, a wire gate used with a barbed wire fence.
BACKGROUND OF THE lNV~NllON
An opening in a wire fence is defined by a first fixed post and a second fixed post. Wire gates used to close the opening, consist of a plurality of wires extending from the first fixed post to a movable post. In order to close the gate, a lower end of the movable post is inserted in a lower wire loop secured to a lower end of the second fixed post. The movable post is then forced into a substantially vertical position, and an upper end of the movable post inserted into a loop secured to an upper end of the second fixed post.
Opening and closing a gate, as described, requires two hands. This causes a problem when a farmer passing through the gate, has one of his hands occupied; as frequently occurs.
There have been previous attempts to develop a gate latch that is capable of one handed operation. An example of such a gate latch is illustrated and described in United States Patent 5,476,133 which issued to Torkelson in 1995.
SUMMARY OF THE lNv~NllON
What is required is an alternative form of gate latch that is capable of one handed operation.
According to the present invention there is provided a latch for a wire gate which includes a frame defining a post confining enclosure. Means is provided for securing the frame to a fixed fence post in a substantially horizontal orientation. A portion of the frame is pivotally mounted for movement about a substantially vertical axis. The pivotally mounted portion is movable between an open position and a closed position. In the open position the pivotally mounted portion is spaced from the frame thereby providing ingress and egress of a movable fence post to the post confining enclosure.
In the closed position, the pivotally mounted portion rests against the frame. Biasing means urges the pivotally mounted portion toward the closed position. It is preferred that channelling means be provided for directing a movable fence post between the pivotally mounted portion and the frame.
The latch, as described above, enables a person to close a gate with one hand by pushing the movable fence post into the channelling means. As the movable fence post passes along the channelling means, the biasing force of the biasing means is overcome sufficiently to move the pivotally mounted portion to the open position and allow entry of the post into the post confining enclosure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, a latch for a wire gate generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 5.
Referring to FIGURES 1 and 2, latch 10 include a rectangular frame generally indicated by reference numeral 12.
Frame 12 has a first side 14, a second side 16, a third side 18, and a fourth side 20 defining a post confining enclosure 22. A clamp, generally indicated by reference numeral 24, is secured to frame 12. Referring to FIGURE 3, clamp 24 is used as means for securing frame 12 to a fixed fence post 26. Clamp 24 is pivotally secured at first side 14 of frame 12 for pivotal movement about a substantially horizontal axis defined by bolt 28. This enables frame to be moved between a substantially horizontal operative orientation as illustrated in FIGURES 4 and 5, and a substantially vertical stored or inoperative orientation as illustrated in FIGURE 3. Referring to FIGURE 1, a bolt 36 is used as a rotational stop to maintain frame 12 is a horizontal position relative to clamp 24. Bolt 36 is secured by a nut 46. Referring to FIGURES 1 and 2, clamp 24 includes a first clamping member 30 and a second clamping member 32. Clamp 24 is attached to frame 12 by means of a pair of attachment brackets 34 secured by bolt 28 and nut 38. First clamping member 30 and second clamping member 32 are maintained in clamping engagement by bolts 40 and nuts 42.
Fourth side 20 is pivotally mounted to frame 12 for movement about a substantially vertical axis defined by a hinge 44.
Pivotally mounted fourth side 20 is movable between an open position illustrated in FIGURE 4 and a closed position illustrated in FIGURES 1, 2, and 5. Referring to FIGURE 4, in the open position, pivotally mounted fourth side 20 is spaced from third side 18 of frame 12 thereby providing a movable gate post 48 with ingress to and egress from post confining enclosure 22. Referring to FIGURES 1 and 2, in the closed position, pivotally mounted fourth side 20 rests against thirds side 18 of frame 12. A biasing spring 50 on hinge 44 urges pivotally mounted fourth side 20 toward the closed position.
A first guide member 52 is positioned at a remote end 54 of pivotally mounted fourth side 20. A second guide member 56 is secured to third side 18, extending away from post confining enclosure 22. First guide member 52 and second guide member 56 form a generally "V" shaped channel, generally identified by reference numeral 58. A generally "U" shaped clip 60 is secured by a chain 62 to frame 12.
The use and operation of latch 10 will now be described with reference to FIGURES 1 through 5. Referring to FIGURE 3, frame 12 is secured to fixed fence post 26 by means of clamp 24. Frame 12 is pivoted to the inoperative position when not required. When required, frame 12 is pivoted to the operative substantially horizontal position illustrated in FIGURES 4 and 5. Referring to FIGURE 4, in order to close latch 10 using one hand, movable gate.post 48 is pushed into "V" shaped channel 58. As movable gate post 48 passes along "V" shaped channel 58, it is directed between pivotally mounted fourth side 20 and third side 18 of frame 12. The biasing force of biasing spring 50 is overcome sufficiently to move pivotally mounted fourth side 20 to the open position and allow entry of movable gate post 48 into post confining enclosure 22. Referring to FIGURE
5, once movable gate post 48 is within post confining enclosure 22, spring 50 returns pivotally mounted fourth side 20 to the closed position. In order to ensure that pivotally mounted fourth side 20 remains in the closed position and does not prematurely release movable gate post 48, "U" shaped clip 60 may be used. "U" shaped clip 60 is slidable over first guide member 52 and second guide member 56 to maintain pivotally mounted side 20 in the closed position.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
