for engaging the vertical environmental object such as a door jamb or wall. The wall cup 38 is fixable to the door jamb or wall by a pin connector 40 such as a screw. Hidden from sight is a rotatable disk on the end of the shaft 34 that is received by the wall cup 38. The threaded shaft 34 may or may not be threadingly engaged with a respective corner portion 42, 44, 46, 48 of the frame 20 and frame extension 30. Preferably the threaded shaft 34 slides into and out of its respective corner portion 42, 44, 46, 48 without being threadingly engaged. The frame 20 and frame extension 30 hold the gated barrier 18 in place, and optionally off the floor, by the hand wheel 36 being turned so as to increase the effective distance of the shaft 34 between the hand wheel 36 and the disk in the wall cup 38. The hand wheel 36 abuts the corner portion 42, 44, 46, 48 and the disk abuts the wall cup 38 that is engaged to the door jamb or wall. When such effective distance is increased, one result is to pressurize the frame 20 and frame extension 30. In other words, one or more of the standards 24, 26 are manufactured to be oblique relative to the lower horizontal support 28. However, when the frame 20 and frame extension 30 are pressurized by increasing such effective distance, such one or more standards 24, 26 are drawn into a right angle relationship with the lower horizontal support 28, thereby drawing the upper portion of standard 26 into engagement with the latch 14 of the latch apparatus 10.

The gate 22 includes outer or end support members 50, 52. End support member 52 defines the pivot axis of the gate 22. Gate 22 further includes an upper horizontal or transverse support member 54 and a lower horizontal or transverse support member 56. Gate 22 further includes, disposed between end support member 50, 52, a set of vertical support members 58, 60, 62, 64, and 66 that extend from the lower horizontal support member 56 to the upper horizontal support member 54. Vertical support members 50, 58, and 60 extend into the latch apparatus 10 and are engaged to the upper horizontal support member 54. In FIG. 1A, the latch apparatus 10 is closed and the gate 22 is closed.

FIG. 2A shows a front view of the latch apparatus 10. Latch apparatus 10 includes a spring loaded slide lock 68. Slide lock 68 is mounted on the upper horizontal member 54 of gate 22. An internally mounted spring 70, shown in FIGS. 9A, 9B, 9C, and 9D, biases the slide lock 68 toward the housing 12. Slide lock 68 includes a main body 72 and a ledge 74 extending from the main body 72. Ledge 74 extends in the direction of the housing 12. Ledge 74 includes an oblique upper portion that extends downwardly and toward the latch apparatus 18 such that the lever 16 can snap back into a locking relationship with the slide lock 68.

Lever 16 swings or pivots on a pivot pin 76. Pivot pin 76 engages the housing 12, further engages the latch 14, and further engages the gate upper horizontal support member 54. Pivot pin 76 is secured to the latch apparatus 16 by a lock washer or clip 77.
