ACTIVE SECURITY SYSTEM
An active security system with a rotating spoke and hub apparatus with razor wire, barbed wire or other types of sharp objects affixed to the spokes that is free standing or on top of an existing fence or wall and mounted to stationary columns. A motor and linkage provide for the active rotation of the rotating spoke and hub structure. The motor is activated by sensors that detect a presence of an intruder.
1. Field of the Invention (Technical Field)
The presently claimed invention relates to security systems and more particularly to a rotating structure affixed to a top of a stationary structure that is actively rotated on demand.
2. Background Art
Presently there are several types of passive security devices for impeding intruders from entering or exiting a secure area. These include walls, fences, and other types of barriers. To enhance these types of designs, additional deterrence devices have been added, such as broken glass, razor wire or projections from the top of the wall or fence. However, these are also passive devices that can easily be overcome by a determined intruder. This type of device is shown in U.S. Pat. No. 4,602,764. There are also several prior art systems that have rotating structures with spikes or blades used as a deterrent; however these structures are not active in that a person causes the rotation when attempting to scale the structure. These include U.S. Patent Application No. 2005/0189529, U.S. Pat. No. 4,739,970, U.S. Pat. No. 4,270,736, and U.S. Pat. No. 5,310,163.
SUMMARY OF THE INVENTION Disclosure of the InventionThe presently claimed invention overcomes the shortcomings of the prior art by providing an active deterrent system with a driven rotating apparatus with spikes or blades that is activated by sensors or manually with a switch. This type of system is preferable to existing systems, especially for high security areas. Further, by using the presently claimed invention, fewer guards are necessary to secure a facility.
In a first embodiment, a rotating assembly comprising a spoke and hub axel mechanism with razor wire, barbed wire, spikes or blades are attached to rotary spokes. This embodiment is affixed to a top portion of a fence, such as a chain link fence or a wall. The rotating assembly is affixed to stationary supports with a rotating shaft encased by a bearing assembly and the shaft driven rotationally by a pulley or sprocket driven by a fan belt or chain. A motor provides the drive to the belt or chain. The motor can be activated by sensors, such as light sensors, motion sensors, pressure sensors or the like. Optionally, the motor can be activated by a manual on/off switch. The control box can also deactivate the motor with a timer or by a manual switch.
In a second embodiment, the shaft comprising a first diameter can be inserted into a specific length of a larger diameter pipe at each stationary support, the length of large diameter pipe attached to the stationary support with a clamp or the like and the spoke, an axel mechanism affixed to the shaft and driven as in the first embodiment.
In a third embodiment, the rotating assembly is a free standing assembly affixed to stationary supports with the rotary spokes near but not touching the ground level. The drive mechanism is as previously described and this embodiment can also include bearings or the inserted shaft embodiments.
A primary object of the presently claimed invention is to provide an active deterrent for entry or exit to or from a high security area.
A primary advantage of the presently claimed invention is that it cannot be easily compromised and when activated will provide additional visual and auditory deterrence.
Other objects, advantages and novel features, and further scope of applicability of the presently claimed invention will be set forth in part in the detailed description to follow, taken in conjunction with the accompanying drawings, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the claimed invention. The objects and advantages of the claimed invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
The accompanying drawings, which are incorporated into and form a part of the specification, illustrate several embodiments of the presently claimed invention and, together with the description, serve to explain the principles of the claimed invention. The drawings are only for the purpose of illustrating a preferred embodiment of the claimed invention and are not to be construed as limiting the claimed invention. In the drawings:
The presently claimed invention is a system and method to control access or egress to security areas, such as operating areas for correctional facilities, department of defense facilities, or other private areas of high security. The composition of the claimed invention is a steel structure assembly consisting of support elements with a spoke hub assembly that will rotate on electrical control demand.
Although the claimed invention has been described in detail with particular reference to these preferred embodiments, other embodiments can achieve the same results. Variations and modifications of the presently claimed invention will be obvious to those skilled in the art and it is intended to cover all such modifications and equivalents. The entire disclosures of all references, applications, patents, and publications cited above, are hereby incorporated by reference.
