The present disclosure relates to a falling and death leap defense rotating cylinder system, including a supporter; a rotator that is rotatably installed in the supporter, and that inhibits a death leap of a death leap attempter by rotating when grasped by the death leap attempter; and a spiked unit that forms a cutting edge, and that is detachably installed in any one or more of the supporter and the rotator. According to the present disclosure, by the spiked unit detachably installed in the supporter or the rotator, a falling and death leap of a death leap attempter may be inhibited more effectively.

A doorway and passage barrier having a plurality of freely rotating members engaged upon a mounting member positioned upon a top edge of a frame of a child or pet barrier. The rotating members positioned adjacent the top edge of the frame form a bi-rotational shield preventing stationary contact with the top edge of the frame, thereby preventing a child or pet from using the top edge of the frame as a hand grip or foot positioner to climb over the barrier.

The invention disclosed in this application is a non-injurious ascension barrier for mounting on the top of security walls or fences. The invention is cylindrical in shape with the curved sides extending out from the sides of the wall or fence to which it is affixed to prevent the climber from reaching the top of the fence or the wall. The product is sufficiently rigid to prevent the climber from compressing the extending sides into handholes yet may be sufficiently flexible to bend vertically to horizontally to follow the contours of the wall or fence top as the wall or fence changes in elevation or direction to follow the contours of the land.

A device for canine containment includes a pair of opposing brackets, each including a mounting portion and support plate, and two pins extending perpendicularly therefrom aligned in a vertical plane. The device includes two hollow cylindrical rods configured to hang from and roll freely around each set of upper pins and lower pins extending from opposing brackets. The pair of opposing brackets with the two hollow cylindrical rods mounted therebetween form a unit configured to place atop a fence panel intact and fixed thereto. A method of installing the device includes adjusting a length of the rods based on a distance between adjacent fence posts; mounting ends of upper/lower cylindrical rod, over upper/lower pins; pushing opposing brackets toward each other, and mounting the device intact onto the fence panel via the mounting portions; and sliding each of the opposing brackets outward until each rests flush against the adjacent post.

An improved system, apparatus, and methods for a pet and child confinement gate providing enhanced safety and deterrence of climbing attempts. The confinement gate includes first and second brace portions with an innovative locking system. A drop-in catch engages with a metal sheath by lifting and lowering the gate, providing a primary locking feature. A rotatable knob, when turned, extends a sliding bolt into a receiver hole on the opposite brace, securing the gate against all directions of movement. The top of the gate features a free-spinning mechanism, which may include cylindrical rollers or ball-bearings, equipped with noise-making loose objects and sensors to deter and detect climbing attempts. The free-spinning mechanism can also trigger auditory deterrents via an audio device and send alerts through communication circuitry to a caretaker's device, further enhancing security measures.
