DEPLOYABLE BALLISTIC SHELTER
A deployable ballistic shelter includes a rear ballistic panel abutting a room wall; first and second side ballistic panels movable relative to the rear panel; and a front ballistic panel coupled to the side panels. The ballistic panels can be arranged into a wall assembly. An actuation assembly transitions the side and front panels between a stowed position and a deployed position forming an enclosed perimeter. A local authorization switch can be operable to deploy and stow the shelter. The shelter can receive a signal from a central control system via a communications network to deploy. Multiple shelters can be coordinated by the central control system, and duplex installations across a shared wall may omit rear-wall ballistic panels.
The safety and security of students and staff in school environments has become increasingly critical in recent years, particularly in response to a growing number of active shooter incidents and other emergency situations. In such scenarios, the ability to provide immediate and reliable protection can significantly reduce the risk of injury or loss of life. Ballistic shelters, designed to withstand gunfire and other threats, offer a potential solution for enhancing security within school classrooms and other educational facilities.
Traditional approaches to improving classroom security have included reinforced doors, lockable entry systems, and lockdown drills. Potential victims often hide in closets, storage cabinets, or beneath desks or tables. Current measures do not provide an adequate level of protection against firearms. While existing measures are essential, they may not provide sufficient protection in situations where evacuation is not possible or when the threat occurs within the building. Portable and fixed ballistic barriers have been deployed in some environments, but these solutions often lack the rapid accessibility, scalability, and discreet integration required for use in educational settings.
Despite the critical need for such solutions, current options for ballistic protection in classrooms often fall short in terms of practicality, cost-effectiveness, and user-friendliness. Existing solutions are either ineffective, prohibitively expensive, difficult to deploy, or unsuitable for integration into standard classroom layouts.
In light of these challenges, there is a clear and pressing need for an innovative ballistic shelter specifically tailored to the unique requirements of school classrooms. Such a shelter would enhance the safety of students and staff by providing immediate and effective protection during emergency situations, contributing to a more secure and resilient educational environment.
The foregoing aspects and many of the attendant advantages of the present disclosure will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
The following description provides several examples that relate to configurations of apparatuses for deployable ballistic shelters, and more specifically, shelters configured to deploy and house occupants for protection from threat of an active shooter, e.g., in a school classroom environment. A deployable ballistic shelter (also referred to herein as a “ballistic safety room”) is designed for use in any suitable room, such as classrooms, offices, conference rooms, and other room types. The shelters described herein include features that are expected to provide one or more of the following benefits: (1) a sufficient level of ballistic protection, capable of withstanding rounds from commonly used firearms; (2) straightforward and quick deployment, permitting occupants to access the shelter in an emergency without requiring extensive training or additional equipment; (3) compact and unobtrusive, integrating into the classroom or other room environment without disrupting day-to-day activities or occupying excessive space; (4) construction of durable materials for longevity; (5) straightforward installation procedure; and/or (6) comfort and capacity considerations, ensuring it can accommodate the occupants within the installation room and any designated additional occupant room, while providing adequate ventilation and communication capabilities during extended use. Hereinafter, the deployable ballistic shelters are described in the context of an installation in a classroom setting; however, embodiments of the present disclosure are suitable for use in any room type where the safety of a ballistic shelter is desired.
In some embodiments of the present disclosure, the shelters are offered in three levels of ballistic protection, including UL 752 Levels 3, 5, and 8. Shelters rated at level 8 may provide protection against certain assault-style rifle threats. However, other ballistic protection levels can be achieved by the ballistic shelters disclosed herein and are within the scope of the present disclosure.
By way of example, deployable ballistic shelters of the present disclosure can have any suitable deployed footprint, such as a deployed footprint of about 16 feet wide by about 4 feet deep, and any suitable height, such as a height of about 8 feet. Some embodiments can be configured to shelter about 30-40 individuals, depending on their size, with other sizes being within the scope of the present disclosure. An optional ceiling module is shown in
In some embodiments, the ballistic shelters of the present disclosure include a local authorization switch adjacent to each shelter for regular system checks, and/or for an authorized person to reset the ballistic shelter to its stowed position and to prevent unauthorized deployment. The local authorization switch can be used to control a single local shelter, or to send a network command to deploy one or more shelters in nearby classrooms, in certain buildings, and/or campus wide. The authorization switch can be authenticated and operated using any suitable security authentication device, such as a physical key, authorized user fingerprint, RFID device, voice authentication, authorized user retina/retinal scan, other authorized user biometrics, or any other security authentication scheme.

In some embodiments, one or more access pass-through openings 160 can be formed through the shared wall 104 (and, where present, through corresponding structural frame components) to permit occupant movement between rooms 100 and 100′. The illustrated embodiment shows four access pass-through openings 160a, 160b, 160c, and 160d with structural frame components therebetween. In other embodiments, one or both of the shelters 110d and 110d′ can include rear panels, such as the rear panels 113a-d shown in
After deployment of any of the shelters 110 described herein, the access door 117 can be held closed by a magnetic force to be opened from the outside in an emergency. Once occupants have entered the shelter 110, the access door 117 can be securely closed with a three-point mechanical latch or other equivalent security latch from the inside.
As shown, the control panel 140 can include a housing 302, a front panel 304, a battery monitor 306 on an external surface and electrically connected to an energy storage device 320 (e.g., a battery). The battery monitor 306 can permit an operator to read the voltage and other battery health information, and provide service. The control panel 140 can include various circuits and other features on a board 310 having a power converter 312. The board 310 can include, e.g., a power management circuit, a communications system, and other components to operate the shelters 110 of the present disclosure. Wiring to the motor 206 of the actuation assemblies 130 can include a power input wiring to 48VDC to 12VDC converters 312. In some embodiments, due to the heavy weight of the ballistic fiberglass material, and the need to operate in school classrooms or other locations unlikely to be provided with three phase power supplies, the ballistic shelter can deploy using 48VDC motors using the converters, without the need for the conventional 3- phase electrical service that would otherwise be required. These motor assemblies may be assembled and tested in any suitable light industrial manufacturing facility.
The local authorization switch 150 can include a momentary operation to deploy/stow the shelter. The control panel 140 can be in communication with a central control system to operate the shelters 110, for example, to deploy all the shelters in a system in response to an active threat upon receiving a deployment or stowage signal. As used herein, a signal includes a wired or wireless electrical or digital communication, including a command message transmitted over a communications network. In some embodiments, the central control system can be configured to deploy only a selected subset of the shelters 110, for example, deploying only shelters in a specific hallway/building or forgoing deployment when a room is unoccupied during a threat.
As used herein, the communications network/facility control network can have a dedicated network installed for the ballistic shelters, operating independently from an existing school IP network or Internet connectivity. In some embodiments, the facility control network includes a wired multi-drop communications bus and/or local wired connections between shelters and a central control system. In further embodiments, the central control system can optionally interface with a building or campus emergency alert system to receive a deployment signal.
The shelters can include other safety features, such as proximity sensors to pause, halt, and/or reverse deployment if a person is within the deployed footprint, one or more indicators (e.g., lights and/or a display) configured to indicate deployment status, and control of actuation speed (including variable or limited speed) suitable for operation in proximity to room occupants, voice activation of the access door lock, RFID or other identification systems to provide access to authorized individuals, etc. Although various options and configurations are shown in the FIGURES, other suitable configurations of the shelter are also within the scope of the present disclosure.
Embodiments of the deployable ballistic shelters 110 of the present disclosure include various components. In an example, the shelter 110 includes a modular steel frame wall assembly coupling the panels 112a-d, 113a-d, 115, and 119, which can be fabricated, e.g., from sheet metal at a manufacturing facility, and assembled on site by the installer. The panels 112a-d, 113a-d, 115, and 119 can be ballistic fiberglass mounted in the modular steel frame, e.g., panels available in several thicknesses corresponding to the protection level desired, for example, UL 752 Level 3, 5 or 8, where additionally, the panels can be water-jet cut for accurate assembly and fitment.
In each of these embodiments, a connection to a conventional 120 VAC power supply having a power input may be required to charge and condition the energy storage device 320 between deployments; however, the embodiments can be operated without the conventional power supply so that the system is failsafe from the perspective of power failures. The control panel 140 can be connected to the facility control network, which can be configured to transmit a deployment signal in the event of an alarm and monitor individual shelter status at all times. The control panel 140 can be assembled and tested in any suitable light industrial manufacturing facility.
An exemplary method of deployment of the ballistic shelter 110 will now be described in greater detail. During deployment, the following steps may occur:
-
- (1) initiating a deployment signal at a central control system, including in response to a manual deployment trigger, an external emergency alarm/alert system, or an automated facility input;
- (2) transmitting, via a communications network, the deployment signal to all deployable ballistic shelters or to a selected subset of deployable ballistic shelters, causing the addressed shelters to deploy; (which, as noted above, can occur, for example, in less than about 30 seconds), in some embodiments, initiating deployment at one or more shelters via a local deployment command independent of the central control system;
- (3) a teacher or other authorized individual opening the entry door of the ballistic shelter, which in some embodiments can be held closed by a magnetic latch prior to opening to prevent potential jamming of a mechanical latch;
- (4) the intended occupants (e.g., students) entering the ballistic shelter;
- (5) the final person entering, the teacher, or other individual closing the entry door, which is secured from inside with a locking mechanism, for example, a three-point heavy-duty latching mechanism; and
- (6) optional monitoring cameras and screens can be viewed so that the shelter occupants can monitor the scene outside the shelter, avoiding unintentionally opening the shelter door after hearing a false all-clear message prior to apprehension of the active shooter by the authorities, resulting in injury to the occupants.
Once a ballistic shelter of the present disclosure is installed, teachers and/or authorized users can be trained in the use of the shelter, and regular drills can take place to ensure that the system performance is adequate. In some embodiments, a regular inspection and test protocol may be required to ensure that all aspects of the ballistic shelter are functional for emergency use.
Further embodiments of the shelters 110 described herein can include any combination of the following features in addition to those described above: (1) left or right facing access door; (2) interior dome camera for monitoring of occupants over the building network; (3) exterior dome camera for monitoring of surroundings by shelter occupants; (4) proximity wall mount workstation & tech cabinet for use by occupants; (5) communication device (e.g., microphone) and listening device (e.g., speaker); (6) interior LED strip lighting; (7) O2 Monitor Sensor connected to the building network; and (8) collapsible fabric chairs for use by occupants.
The foregoing options for the deployable ballistic shelters are intended to describe examples of possible options compatible with the embodiments of the present disclosure. Although specific examples are noted above, further options are also compatible with the shelters of the present disclosure and are also within the scope herein.
The principles, representative embodiments, and modes of operation of the present disclosure have been described in the foregoing description. However, aspects of the present disclosure, which are intended to be protected, are not to be construed as limited to the particular embodiments disclosed. Further, the embodiments described herein are to be regarded as illustrative rather than restrictive. It will be appreciated that variations and changes may be made by others, and equivalents employed, without departing from the spirit of the present disclosure. Accordingly, it is expressly intended that all such variations, changes, and equivalents fall within the spirit and scope of the present disclosure as claimed.
