  • Patent number: 10815723
    Abstract: The safety barrier gate with alarm comprises a gate, an approach sensor, a pressure sensor, and an alarm. The gate may be adapted to block a passage to restrict the movement of a child. As non-limiting examples, the passage may be a doorway or a hallway. The alarm may warn when the approach sensor detects that the child has entered a protection zone that is located on a front side of the gate or when the pressure sensor detects that the child is in the process of climbing the gate. The alarm may selectively provide an audible indication upon detection by the approach sensor or by the pressure sensor. The audible indication may alert an adult to an attempt by the child to leave an area of confinement.

  • Patent number: 5461364
    Abstract: An intrusion detection device that can be used singly or in multiplicity to immediately and silently alert the user of attempts to climb over a security fencing system. The invention consists of a base element which attaches to the security fencing, and an alarming arm. The alarming arm is equipped with barrier material, such as concertina wire or barbed wire. The alarming arm is connected to the base element both at a pivot point and through a tensioning means. Attempts to climb over the barrier material result in additional loading of the alarming arm which rotates transversely about the pivot point, and against the force of the tensioning means. This rotational displacement of the alarming arm enables an electrical sensing device which then signals that an intrusion is in progress.

    Abstract: An attachment to a fence, such as a chain link fence, used to confine a dog, prevents the dog from climbing the fence or using the top of the fence to assist himself in escaping over the fence. The attachment creates a region of instability, superjacent the top of the fence, which will not support the dog's weight and thus does not allow the dog to cling to or push off of the top rail of the fence. The region of instability is created by a freely rotatable roller attachment or a flexible panel attachment, both of which yield under the weight of the canine.

A series of relatively short turn cylinders are rotatably mounted, end-to-end, about the bearing member. A plurality of spine-like members extend radially outwardly from the surface of each rotatable member in spaced relationship precluding purchase by an animal's leg or paw. The spines are preferably yieldable so as to substantially minimize injury to climber, with rotation of the spine carrying member precluding a purchase by means of which the climber might pull itself up and over the fence.

  • Patent number: 4081177
    Abstract: An outrigger arm assembly to prevent a would-be intruder from successfully climbing over a fence. The outrigger arm assembly is mounted on top of the fence. Each hollow fence post is interconnected to a hollow outrigger arm by a replaceable collar which breaks when a load in the range of 20 to 30 pounds is applied to the outrigger arm, resulting in the downward movement of the outrigger arm, and the fall of the climber. The assembly also includes a movement sensor, within the hollow arm, which is activated and provides an alarm signal, when the outrigger arm is moved more than a predetermined number of degrees, such as the downward movement of the outrigger arm. The assembly further includes a coiled spring, positioned within the hollow fence post and extending into the hollow outrigger arm, by which the arm is automatically returned to its original defensive position, after the load is removed.
