1. Field of the Invention
The present invention is directed to an expandable gate operative to selectively inhibit movement through an opening and, more specifically, to a latching mechanism for an expandable gate having a latch adapted to be selectively gripped to disengage the latch and enable the gate to be compressed.
2. Background of the Invention
A variety of gates are known and presently on the market that are designed to prevent children from passing from one area to another. Several of these gates can be adjusted for use in openings having various widths.
Presently there are two common types of adjustable, pressure mounted, security gates that are used in the home for children and pets that have a plurality of panels that are roughly adjusted to fill the passageway in which they are to be used. One type has extendable bumpers on at least one side to firmly engage the side or sides of the passageway to hold the gate in place and the second type that has fixed bumpers on the panels that are caused to firmly engage the sides of the passageway by forcibly extending the panels in opposite directions and locking them in the maximum extended position.
Gates having extendable bumpers may incorporate mechanisms that include numerous interconnecting parts that require precise fits and positioning to interact with each other to extend and retract the bumpers. Gates are also known that utilize actuating mechanisms that include a complex arrangement of links, cranks, pull rods and springs that are interconnected to a pull handle. An example of such an actuating mechanism is disclosed in U.S. Pat. No. 5,052,461.
SUMMARY OF THE INVENTIONThe present invention is directed to an expandable gate operative to selectively inhibit movement through an opening and, more specifically, to a latching mechanism for an expandable gate having a latch adapted to be selectively finger gripped to disengage the latch and enable the gate to be compressed. The gate latch may include a pair of spring biased arms that are adapted to receive a component of the latching mechanism therein to fix the relative dimensions of the expandable gate. The gate latch may be finger gripped to overcome the bias and release the component of the latching mechanism to allow the relative dimensions of the expandable gate to substantially change.

The active clasp 84 includes two pivoting arms 86, 88 divided by a partition 90 within the latch 72. Spanning between the loop 82 and the boxed end 76 are two metal rods 92, 94. The metal rods 92, 94 are offset, with the first rod 92 piercing a rounded projection 96 associated with the first pivoting arm 86, and the second rod 94 piercing a rounded projection 98 associated with the second pivoting arm 88. Two receivers 100, 102 are divided by the partition 90 and mounted thereto, with the first receiver 100 including a rounded cavity 104 that receives the rounded projection 96 of the first arm 86 and allows the rounded projection 96 to pivot therein. Likewise, the second receiver 102 includes a rounded cavity 106 that receives the rounded projection 98 of the second arm 88 and allows the rounded projection 98 to pivot therein. The partition also includes a passageway 108 therethrough that is traversed by a spring 110 concurrently mounted to the arms 86, 88.

After the catch 70 is positioned within one of the troughs 66, the second cantilever segment 60 is pivoted with respect to the first cantilever segment 58 such that the latch 72 is moved downward toward the first cantilever segment 58. This pivoting action by the cantilever segments 58, 60 exerts an outward pressure upon the sections 12, 14, thereby tending to wedge the sections 12, 14 within the opening. If the width of the opening is too narrow based upon the position of the catch 70 within a particular trough 66, the second cantilever segment 60 may not properly pivot with respect to the first cantilever segment 58. An attempt to force the latch 72 to downwardly engage the first cantilever segment 58 under these circumstances would result in undue stress upon the cantilever segments 58, 60, and might result in failure of the cantilevers. Alternatively, the catch 70 may be positioned within a trough 66 that enables the latch 72 to engage the first cantilever segment 58, but does not wedge the gate 10 within the opening. In either circumstance where the initial position of the catch 70 within one of the troughs 66 did not adequately allow the sections 12, 14 to be wedged within the opening, the catch 70 may be repositioned to be seated within another trough 66. The above process may be repeated until the latch 72 is mounted to the first cantilever segment 58 and the gate 10 is wedged within the opening. In this exemplary embodiment as shown in

The biased arms 86, 88 of the latch 72 allow for selective disengagement between the cantilever segments 58, 60 by finger gripping. To disengage the latch 72 and the second cantilever segment 60 from the first cantilever segment 58, the biased arms 86, 88 are gripped and directed inward approximate the partition 90 to pivot the tapered ends of the arms 86, 88 outward and disengage the recesses 126 from the bottom of the first cantilever segment 58. The wedge force created by the cantilever segments 58, 60 in an engaged position is decreased as the latch 72 and second cantilever segment 60 pivot away from the first cantilever segment 58 and enable the gate sections 12, 14 to freely move with respect to one another. The decrease in wedge force backs away the bumpers 27, 47 from the boundary of the opening, thereby allowing the gate 10 to be resized and/or repositioned relative to the boundary.
