Barriers, such as window blinds, such as venetian blinds, and vertical blinds, screens, shields, etc. may be used in residential and commercial applications as window coverings, screens, barriers, etc. to act as a physical barrier, and because of their ability to selectively vary the amount of light passing through a window, glass door, skylight, or the like, by the varying deployment, or adjustment of a plurality of vanes, louvers or slats.
Current anti-ballistic protection systems in residential and commercial applications such as armored doors, shutters, and windows are usually made of metal or a material containing at least one metal plate, and thus having an extremely high weight. Some plastic systems exist that have lower weight, but that are very flimsy and weak, and thus would provide no protection from projectiles or other forced entry into the dwelling.
It would be useful to utilize the widespread use of various types of barriers to provide unauthorized entry protection to individuals and organizations in residential, commercial, government, federal building and mobile or any suitable application.
The following presents a simplified summary in order to provide a basic understanding of some example aspects described in the detailed description.
Provided is a barrier comprising material having anti-ballistic properties to prevent penetration by a ballistic projectile, such as a bullet.
In one aspect, a system for protecting a space from ballistic objects using a deployable barrier is provided, comprising: a mounting structure configured for storing the deployable barrier in a retracted position; the deployable barrier comprising a flexible anti-ballistic material formed into a flexible sheet; and a deployment mechanism configured to drop the deployable barrier into a deployed position such that the barrier protects the space from entry by a ballistic object, said barrier being configured to flex and move in response to impact from the ballistic object to absorb energy from the ballistic object to further protect said space from the ballistic object.
In another aspect, a barrier system is disclosed herein including a control system operably configured to cause a change in state of the barrier from an open or retracted state to a protective state; and a sensing system operably configured to detect a threatening event, in which the sensing system upon sensing the threatening event triggers the control system to transition to the protective state.
In still another aspect, the above barrier systems may be configured to secure sides and/or bottoms of the barrier, when deployed, to prevent an individual or large object from entering the space.
In another aspect, a blind system is disclosed herein including a plurality of slats having a ballistic resistant material; a control system operably configured to cause a change in state of the blind from an open state to a protective closed state; and a sensing system operably configured to detect a threatening event, wherein the sensing system upon sensing the threatening event triggers the control system to transition from the open state to the protective state such that in the protective state, the blinds are adapted to be resistant to penetration by high-speed ballistic objects.
In yet another aspect, a blind system is disclosed herein including a blind suspended from a rail and a blind adjustment system that is configured to transition the blinds from an open state to a closed, protective state in which the blinds are adapted to be resistant to penetration by high-speed ballistic objects.

In a further aspect, an anti-ballistic window blind system is provided that is configured for providing in the window of a structure having an interior, the system comprising: a mounting structure; a blind suspended from the mounting structure and configured to be retracted toward the mounting structure to expose the window and deployed from the mounting structure to cover at least a portion of the window, the blind comprising non-metallic material having anti-ballistic properties; mechanical components associated with the mounting structure for automatically deploying the blind into an anti-ballistic protection mode for protecting the interior of the structure from ballistic objects attempting to enter through the window; a sensing system for detecting threat data indicating a ballistic threat exists; and a control system configured to receive the threat data from the sensor, the control system operably configured to trigger the mechanical components to automatically deploy the blind into the anti-ballistic protection mode based on the received threat data.
In still another aspect, anti-ballistic window blind system is provided that is configured for providing in the window of a structure having an interior, the system comprising: a valance configured to be mounted at a window; a blind suspended from the valance and configured to be retracted toward the valence to expose the window and deployed from the valence to cover at least a portion of the window, the blind comprising a plurality of slats, wherein each of the slats is comprised of a non-metallic material having anti-ballistic properties, and wherein the slats are configured to be rotatable when the blind is deployed from the valence for allowing light from the window through the blind; mechanical components associated with the valence for automatically deploying the blind into an anti-ballistic protection mode for protecting the interior of the structure from ballistic objects attempting to enter through the window, wherein the automatically deploying the blind into an anti-ballistic protection mode includes rotating the slats into a closed position if the slats were in an open position, and/or automatically deploying the blind if the blind was in a retracted position; a sensing system for detecting threat data indicating a ballistic threat exists; a control system configured to receive the threat data from the sensor, the control system operably configured to trigger the mechanical components to automatically deploy the blind into the anti-ballistic protection mode based on the received threat data; and a user actuated device configured to trigger the control system to deploy the blind into the anti-ballistic protection mode when actuated.

Any of the above systems may utilize manual or automated deployment mechanisms to protect a room or space from a ballistic threat.
This summary is not an extensive overview of the features and systems discussed herein. It is not intended to identify key/critical elements or to delineate the scope of such features and systems. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description.
The features and advantages of the example embodiments described herein will become apparent to those skilled in the art to which this disclosure relates upon reading the following description, with reference to the accompanying drawings, which show some of the example embodiments of the disclosed devices.
This application includes modifications and additional alternatives to the bullet proof blinds disclosed in U.S. patent application Ser. No. 14/476,206 filed on Sep. 3, 2014, and U.S. patent application Ser. No. 15/050,639 filed on Feb. 23, 2016, both incorporated herein by reference and substantially reproduced herein below.
This application includes modifications and additional alternatives to the bullet proof blinds disclosed in U.S. patent application Ser. No. 16/215,162, filed on Dec. 10, 2018, and incorporated herein by reference and substantially reproduced herein below.
There are various proposals for improving ballistic protection of individuals and interior spaces in buildings and vehicles as discussed in the related patent applications listed at the top of this application. The inventor has discovered that a problem with many current solutions to these problems is that the protection devices don't absorb much of the energy that is contained in the ballistic projectiles, such as shrapnel or bullets that have been fired. The inventor has determined that one solution to this problem is to allow the protective device, such as a screen, panel, shroud, blind, or other barrier to hang freely, perhaps in a weighted manner, which allows the barrier to flex, vibrate, flow, sway and otherwise move in response to receiving the projectile, thereby dissipating some of the energy from the projectile that otherwise would remain as kinetic energy. This reduces the amount of damage and potential penetration of the projective with respect to a given amount of projection.
As shown in U.S. patent application Ser. No. 16/215,162 and its related parents, all incorporated herein by reference, various deployable barriers using non-metallic anti-ballistic materials can be formed for use as window blinds and similar barriers that might be provided at various locations in buildings. Use in windows, doorways, hallways, and other interior locations as a deployable barrier that is stowed when not needed provides a way to protect various interior spaces within buildings. Furthermore, barriers can be provided within vehicles in either deployable or fixed manners (or both). Deployable barriers might be used to protect vehicle windows, doorways, hatches, and other access points, whereas permanently deployed barriers could be provided within vehicle voids such as in doors, body panels, and other locations.
Of particular interest for at least some embodiments are barriers that are not fixed on their sides and bottoms, but that may include weights to increase their overall mass. Such barriers are free to flex and move in response to receiving a ballistic projectile, thereby converting at least a portion of the kinetic energy of the projectile into kinetic and heat energy in the barrier distributed across the entire surface area of the barrier. Allowing this free motion actually increases the effectiveness of the barrier by reducing the penetration energy of the projectile, thereby effectively improving the ability of the barrier to protect the desired person and/or interior region.
Of additional interest for at least some other embodiments are barriers that are still designed to flex and move in interior portions, but that are fixed on their sides and/or bottoms (i.e., fixed around a perimeter or portion thereof) in order to add additional stability and strength, such as to prevent a person or large object from entering a protected region. Such barriers are still free to flex and move in response to receiving a ballistic projectile in at least portion of their surface area, thereby converting at least a portion of the kinetic energy of the projectile into kinetic and heat energy in the barrier distributed across the entire surface area of the barrier. However, along with a fixed top, the fixed sides and/or bottom prevent individuals or objects from bypassing or pushing aside the barrier to get into the protected region. Hence, only the perimeter, or a portion of the perimeter, is fixed and secured, whereas an interior portion of the barrier is free to flex, vibrate, and otherwise kinetically absorb the energy of a ballistic projectile impinging on the barrier.
The inner layer 420 can be comprised of a plurality of layers of anti-ballistic material that might include layers including one or more of: plastic, composites, wood, metal, fabric, fiberglass or any other suitable anti-ballistic material including, but not limited to, Kevlar® (which is a synthetic fiber of high tensile strength comprised of poly-para-phenylene terephthalamide) or Lexan® (which is a transparent polycarbonate of high impact strength) or Lucite® (which is a solid transparent plastic comprised of polymethyl methacrylate) or DuPont™ Tensylon® (which is an ultrahigh molecular weight polyethylene anti-ballistic material), or a boron treated cloth, or a plexiglass with anti-ballistic properties, for example, or any combination thereof. Anti-ballistic gel materials such as shear thickening fluids that may be transparent can be used to saturate a material or fill voids (some of these materials harden upon impact and might be comprised of non-Newtonian fluids that that thicken in response to force). Other materials or combinations described elsewhere in this document can also be used as an alternative or supplement these materials.
All of the layers provided in the laminate 400 (that may be used as the barrier layer 100 of
An aspect of the first surface that the bullet hits can be designed to act like a strike face, to slowdown and deform/mushroom the bullet before it hits the inside layers which then stop the projectile. For example, the outside layer can be anodized, coated, plated or treated/coated to provide the first task of slowing and deforming the bullet before it hits the layers that do the heavy lifting.
The outside strike face can have ridges or protrusions to roll the bullet. There could also be a ceramic veneer or layer to act as the strike face. The strike face layer can also be a combination of different technologies such as coating a ceramic veneer, such as to keep the weight down.
The whole barrier assembly can be spring loaded or partial break away to dissipate energy, or to move in an X, Y or Z direction. The strike faces could slide in pockets of the barrier. The hinges can be metal or composite based.
A security film can be applied to the strike face to slow down and mushroom the projectile such as a bullet. The material would not be flammable like glass and other methods currently used, would be safer for schools etc. On lightweight metal barriers or blinds (having metal slats) a coating or layer/foam, or lightweight material slides in to the extrusion or stamping.
The barrier shape can be used to change the roll of the bullet, various angles to get bullet on its side, for example. The point of the first, outer layer (other than surface decorative layer(s)) is to act as a strike face and slow down and mushroom flatten out the bullet/projectile. When glass is in front of the barrier, a security film can be applied to a surface of the glass that acts as a strike face to slow down the bullet.
On light weight metal barriers (e.g., shutters or blinds) a coating or layer of lightweight material such as Tensylon that fastens or slides into the extrusion or stamping. The barriers could also be a clear lexan that darkens with sunlight. The barriers or shutters could also be a laminated/sage glass that darkens automatically or when electricity is applied.
Barriers can also be a shutter made of tensylon that has a metal, ceramic or wood veneer surface, to make that barriers more presentable but also act as a strike face. The slats or edges can also have a metal edge to improve the appearance. Lightweight materials light dyneema can act as a ladder or to keep the barriers aligned. A metal shutter can be a extrusion or stamping that the cavity is filled with a combination of materials foam, coating, kevlar polyurethane, or anti-ballistic gel, depending on the function of providing strength, sound dampening, strike face, decorative, etc. The fabric laminate may also be coated with various substances to help provide decorative features, or to stiffen outer layers to deform bullets, or to provide sound deadening, or otherwise provide other desirable features.
The barriers can be provided in modular sections that can deploy horizontally or vertically. The device can deploy from the top bottom or side. Sections can be provided in fabric or hinged, daisey chained, or wired together. Speakers and/or lights can be provided in various sizes.
The sections can be electrostatic or the equivalent of a thin speaker to block light sound bullet etc. (as described in more detail below). The barriers can provide light or emitted sound. Barriers, such as blinds or shutters can use speakers for security, and can block light and provide sound. Speakers can be provided to vibrate the barriers do active noise cancellation.
Barriers can be designed in a way to dissipate the energy from the shot through motion, destruction, heat dissipation, deformation, or other processes. They may sacrifice themselves much like a formula one car sacrifices itself to save the driver.
A cavity or pockets of the barriers (e.g., blinds or shutters) can be provided to house different modules according to the needs desired or a combination of elements. Slats could rotate on there axis to displace energy or change side according to purpose.
The barriers can be comprised of various layers of fabric material. The material layers may be secured to each other by stitching, quilting, gluing, welding, or merely the edges may be bound and perhaps tacked in a few spots leaving inner layers unsecured to each other, allowing motion or pockets for other uses, such as inserting materials or gels. Perhaps not stitch bonding or perhaps a very open quilt pattern.
A logo can be provided, such as using 1 inch or ¾ inch binding, or by sewing in a logo. As many as 18 plies or more of woven Kevlar fabric or other material can be used in the laminated material. Depending on the weave and year size, the result can meet at least a level IIIa protection, or more. Fabric style can be 600d Kevlar KM2 Plus, 24×24 square yarns per inch, plain weave construction, Polyester stitching yarn, 75 denier textured yarn. Stitch pattern can be: linear chain stitch (machine direction), 3.5 gage spacing. Quilting can be used to secure the layers to each other. Layers secured only at the ends can also be utilized. It is noted that the very looseness, flexibility, and motion of the material aids in energy absorption, providing better ballistic protection and penetration avoidance.
Referring back to
In this generic approach, as discussed above, the barrier layer 110 will be a flexible layer that can move, vibrate, swing, and otherwise convert the kinetic energy of the ballistic projectile into kinetic and/or heat energy in the barrier 100 by nature of having barrier sides 112 and a barrier bottom 114 that are not secured to any structure in this free hanging embodiment. A weighted end 130 can be provided on the barrier layer 110 to add mass to the barrier so that the kinetic energy of the projective is also transferred to this mass as kinetic energy by moving the mass of the end 130, which can include lifting the end, swinging the end, and other types of motion. The end 130 also helps keep the barrier 100 in place by providing stability and in a deployable embodiment, may also help deploy the barrier 100 in emergency situations, as is also discussed in the parent applications.
As an alternative, the side mounting structures 140 may be extended further, even along the entire length of the barrier sides 112, to secure the sides. Furthermore, an optional floor structure 152 can be provided at a bottom of the barrier 100, such as on or beneath a floor, to secure the barrier bottom 114 when deployed. For example, bottom 114 may include a magnet along it's length as part of the weight 130, and the floor structure 152 could include a magnet of an opposite pole (which may be an electromagnet), to secure the bottom 114 to the floor. Alternatively, floor structure 152 might include a latch or gripping device that secures the bottom 114 to the floor. Hence, in conjunction, extended side mounting structures 140 and/or the floor structure 152 secures the barrier 100, when deployed, to prevent individuals or objects from passing beyond the barrier 100 into a protected region.
Note that automatic deployment, based on the detection of a dangerous situation such as an explosion or gunshot (e.g., triggered by sound waves, breaking glass, light flash, or even detection of intruders, for example) can be provided as discussed in the parent applications. Manual deployment through activation of a motor or drop function through use of a switch, lever, or other manual activator can also be provided as an alternative or supplemental means of deployment. The weight 130, when provided, can aid in quick deployment. Such barriers can be provided in windows, doorways, hallways, or even across rooms, for example.
Alternative approaches where the barrier is installed in a rising manner could also be provided. For example, posts may rise out of the ground or floor for deploying the barrier from the ground up, with the top portions free to move, or with sufficient flex in the barrier to allow freedom of motion. Such devices can protect hallways, stages, rooms, doorways, garage doors, or other locations in and out of buildings.
Referring to
The slats could be formed having matching grooves or a tongue and groove system to allow the slats to interlock or overlap with each other in a more secure way to ensure better resistance to ballistic intrusion, as described elsewhere herein. For example, the slats might overlap by ½ inch.
The slats 10 can be of conventional construction but with updated materials, and can be constructed of a number of different materials having desirable properties, including, but not limited to, the following materials: plastic, composites, wood, metal, fabric, fiberglass or any other suitable anti-ballistic material including, but not limited to, Kevlar® (which is a synthetic fiber of high tensile strength comprised of poly-para-phenylene terephthalamide) or Lexan® (which is a transparent polycarbonate of high impact strength) or Lucite® (which is a solid transparent plastic comprised of polymethyl methacrylate) or DuPont™ Tensylon® (which is an ultrahigh molecular weight polyethylene anti-ballistic material), or a plexiglass with anti-ballistic properties, for example, or any combination thereof. Other materials or combinations described elsewhere in this document can also be used as an alternative or supplement these materials.
In an example embodiment, the slats could be provided as a laminate, such as steel or aluminum with a carbon fiber or tensylon or fiber glass backing. Decorative layers or paints can be provided for room esthetics. Also, fabric can be treated with boron to form a ballistic resistant material. For example, a fabric can be dipped into a boron solution, then heated in an oven at more than 1000° C., which changes cotton fibers in the fabric into carbon fibers, such that the carbon fibers react with the boron solution to produce boron carbide.
The slats 10 could vary in shape, width, thickness, and/or orientation to form blinds of various styles and construction, as desired. The slats 10 can be made flat or curved across their transverse dimension, they can be of any desired width or length or thickness, and they could be provided of different dimensions, such as, for example one, two, three, or four inches wide or any other suitable width for the desired application. Rather than horizontal slats, the slats may be arranged vertically, as shown elsewhere in this document. The lengths of the slats for the various blind designs can be varied according to the window or door size that they are being utilized to protect, and they could be of a length of a foot or more, up to 4 to 8 feet or more, as desired.
Turning to the operation of the blind system 5, the slats 10 can be tilted (e.g. by rotation) by a tilt mechanism 50 to let in partial light, such as when a tilt wand or cord 25 is used to adjust the slats 10. The slats 10 can also be lifted or collapsed by a lift mechanism 100 (for example, to fold or accordion the slats into a compact position) to let in full or nearly full light, for example.
Referring to the example embodiment of
As an alternative to rotation, in some embodiments the slats may be opened and closed by sliding the slats or collapsing the slats together, for example. And the entire blind may be retracted toward the top (valence) structure or deployed as desired.
The slats 10 of the blind system 5 further comprise rods 45 routed through rod holes 40. In this example embodiment, each slat 10 comprises at least one rod hole 40. At least one steel rod 45 which is affixed to the head or bottom rail 20 runs through each slat 10. The slats 10 could pivot about the steel rod 45 which is encased in the slats 10. Pulling the lift-cord activates the lift mechanism 100 causing either the bottom rail or the top rail to rise, sequentially collecting the slats from the bottom up or the top down and compressing the entire array of slats 10 against the top-rail.
Turning to
In an example embodiment, the slats 10 may have a groove 65 and and/or tongue 68 that may run the length of the slats 10 to interlock the slats together during deployment. While the embodiment shows the groove runs the length of the slat, it is appreciated that a groove-tongue system located at the edge of the slat 10 may suffice. The groove 65 and tongue 68 allows slats 10 to interlock when they are in a closed position for additional strength. In another example embodiment, the slats 10 can have fasteners that allow them interlock for additional strength. The fasteners could engage with the window or door sill for added strength, if desired. Or magnets or electromagnets might be used to interlock the individual slats together. Another example of such a tongue-and-groove interlocking approach is shown in
Where a building may already have a central control system (e.g., a security or other alarm system), controller 202 may utilize such a system by adding additional customized code for operating the blinds system 5. In another example, the blinds could also utilize ground sourced radar, infrared (heat), sonar, or some other active or passive detection system. The sensor array 204 can include one or more heat sensors, infrared sensors, video sensors, audio sensors, smoke detectors, or other types of sensors, or may utilize already existing sensors of a fire or burglar system, for example. Any of the sensors in the sensor array 204, the panic switch 206 or the user interface 210, or any combination of these components, may be connected to the controller 202 in a wireless manner, such as by WiFi or Bluetooth, for example, and the panic switch and/or user interface could be implemented on a cell phone or tablet computer, for example.
The system or any of its components may be controlled by any external or internal system, such as one that may exist prior to the installation of the blinds. For example, the blind system could be tied to an external system such as an alarm system or video cameras with analytics. The blind system could also be controlled remotely via the internet or a WiFi or Bluetooth connection by any connected device such as a tablet, computer, PDA, or a smartphone. Blinds such as disclosed herein would be very useful in a panic situation in a school or federal building. Such blinds could also be used in a lock down situation to prevent people or valuables from leaving the premises, for example.
The blinds could be retrofitted to an existing building or other structure, and adapted to tap into existing security or burglar alarm systems, for example, or they could be added during structure construction.
The blinds could also be adapted to sense the location of the occupants of the building and close by according to predetermined parameters such as direction of threat and the location inside the building that would be the best to return fire from. Blinds could also be controlled by facial recognition, video analytics, or by the occupants' voice or any other suitable biometrics, such as for recognizing an threatening person, such as an ex-spouse, or ex-employee who has made threats or acted in a threatening manner, or otherwise recognizing a wanted criminal or an enemy soldier, for example. When the blind system 5 is activated, the slats 10 may be configured to overlap each other to form the interlocking pattern discussed above so as deflect bullets, shells, or other ballistic weapons to prevent a fatal impact and/or property damage. Such blinds can protect from thrown objects as well, such as rocks, grenades, bricks, molotov cocktails, etc. Blinds could be controlled individually or together with a timing mechanism.
The blinds could be configured to protect against remote monitoring of sound and conversation, such as by providing random vibrations to the blind to avoid vibration detection by remote monitoring devices, for example.
As an example use, the blind system may be provided in an open state where the blinds are provided in an open condition (e.g., with open slats) to allow viewing through the blinds, or the blinds in a retracted position. The blind system sensor array would detect a potential intruder or the sound of gunfire using visual, auditory, or other sensed information. The system would then automatically enter a protective state, such as by closing the blinds (e.g., closing the slats) or deploying the blind (by lowering it to cover the window), or both, to protect the interior of the room from external entry of projectiles (e.g., bullets), for example. Or the system may detect the entry of a ballistic projectile (e.g., a bullet, rock, etc.), or threatening shouts or yells, sirens, explosions, proximity of threatening individuals, etc., in which case the blinds would be activated into a protective mode.
In an alternate example embodiment illustrated in
In an example embodiment, the slats 110 used between the safety glass panes 135 could be comprised of a composite or laminate, such as fabric with a carbon fiber or tensylon or fiber glass backing or other ballistic resilient backing.
In an example embodiment, the glass panes 135 could have a layer of safety film 140 such as, for example, Cellulose acetate film, 3M safety film, Armor guard films or the like for additional protection. The safety film can be between 4 mil to 10 mil, for example, although other thicknesses could be used. In another example embodiment, the glass panes 135 could be made of fire glass with a gel center such as manufactured by SAFTI First, for example.
In an automobile application, the blind system 105 could be controlled with safety in mind so that a driver does not lose all drivability at once and improving the ability to evade. For example, the blinds could have a small port hole for the driver of the vehicle to see out of to allow the driver to continue to drive toward a safer area, for example. Or the blinds could be comprised of a transparent material with anti-ballistic properties, or a material with anti-ballistic materials woven therein.
In use for mobile applications, such as in boats, or airplanes or automobile, the blind system 105 could be configured to tilt or close the blinds based on temperature, sound, threat, geographic terrain, environmental conditions and any outer suitable factors. For example, as a vehicle goes up a hill, the blinds can be adapted to tilt so that air or light can get in and not bullets.
The blind system 105 could also be fire rated to prevent fire from spreading to the next room or structure through the use of fire retardant or preventive materials, where the blinds can be automatically closed when a fire is detected through monitoring of temperature, light, or infrared, for example.
In another example embodiment illustrated in
In an alternate example embodiment to the slat blind system, the roll up blind system 305 can reside between two glass panes, such as safety glass panes 135 for use in applications like automobiles, airplanes, boats or other mobile applications, as shown in
Any of the protective blinds described herein might also be stored in a ceiling rather than a valance structure, and in some cases bullet proof panels rather than blinds might be used, where deployment in emergency situations means that the blinds drop from the ceiling to provide ballistic protection.
The fabric blind 310 could also tilt or otherwise be operated according to the threat or terrain. The fabric blind 310 could close from the top or bottom depending on the design of the building or application. The fabric blind 310 could also run left to right, for example. The blinds could also tilt according to the threat or terrain. For example with vehicle application when the blind is used as a radiator cover, as the vehicle goes up a hill the radiator blinds tilt so air can get in and not bullets.
In an alternate example embodiment, the roll up blind system 305 may be used for windows, doors, entryways, or any other desired application in a building or vehicle. The roll up blind system 305 could suspend from a rail 315 and that may be disposed within a head box 320 (acting in concert at a valence) and may be weighed down by bottom rail 325 to maintain its position and add structural strength. The weight of the bottom rail can vary to match the desired application, or it may be paired with a structure enhancement such as through the use of electromagnets or a structure secured to a sill or floor. A reel cord 330 may be used to be roll up the blinds 310 or to roll down the blind 310. The reel cord 330 may also be pneumatically or automatically driven, such as by using a chain. The lengths of the blind 310 can be varied according to the window or door size that they are being utilized to protect, and they could be of a length for the desired application.
Generally, any of the blind systems provided herein will typically be provided with blinds that can be placed in an open state at the request of a user to enable viewing through the blinds, and/or to allow for airflow and/or light flow and/or other flow through the blinds. Such blinds can also be closed at the request of a user, in which case the blinds may also be in a protective state. The blinds can also be provided in an intermediate state, able to both provide some limited ballistic protection and to let in a substantial amount of light. Upon detection of a threatening condition, such as detection of a gunshot or a flying projectile, or by activation of a panic button or security system, blinds that are in an open state will be transitioned into a closed, protective state to protect against ballistic projectiles or other threatening materials.
In addition to the embodiments disclosed in the '206 application and described above, various forms of vertical blinds based on concepts provided in that application are also provided. Additional materials are also disclosed for constructing the blinds in this and that application.
The use of a Kevlar fabric having expanding baffles between the layers is one alternative in such blinds. By providing baffles in the material, the material is enabled to expand in an outward direction, which will help to absorb some of the energy provided by a ballistic impact.
The fabric blinds could utilize horizontal or vertical pleats or slats. Separate vanes or material can be provided to add bullet proof functionality, such that existing blind designs, that may have ornamental aspects, can be supported by a set of bullet proof blinds placed underneath the current blind design. The blinds would act in conjunction to open and close in a traditional manner, with the added functionality of providing ballistic projectile protection. Solenoids or motors, or electromagnets, or other electrical or mechanical devices can be used to mechanically open and close the blinds.
In some options, a bullet proof blind (that may be provided behind or in front of a traditional blind or a as a full replacement) may remain normally in a retracted or otherwise open mode. The bullet proof portion of the blind may be hidden in a valence of the blinds, for example, or be rotated or retracted in an open position. The bullet proof material can be automatically deployed, such that upon a triggering event (such as the detection of a gunshot, or the triggering of a proximity alarm or other type of burglar alarm, for example) the bullet proof (ballistic) blind would then deploy, such as by dropping into place from a valance or roof or ceiling, for example.
Such a dropping ballistic blind might be comprised of panels or slats of ballistic material that are folded, overlapped, or otherwise collapsed in the retracted position, or it may comprise a roll of ballistic fabric that rolls to retract, and unrolls to deploy to form a ballistic layer of protection. A weight may be provided at the bottom of the roll to aid deployment (e.g., unrolling) and to help keep the material in place for stopping or slowing the projectiles. Alternatively, some structure to increase the strength of the deployed blind could be used, such as electromagnets or electrical or mechanical latches at the base to secure the deployed blind to the floor or window sill or wall or other structure.
The blinds can be placed between layers of glass, for example, which can be used in original installations or to retrofit existing windows. The blinds may be used in conjunction with bullet proof or bullet resistant glass. For example, blinds such as disclosed in U.S. Pat. Nos. 5,826,338 & 6,070,638, incorporated herein by reference, could be modified using the materials disclosed herein to add ballistic protection to such blinds. Automatic deployment functions, as also described herein, could also be provided.
In particular, vertical blinds (or shades) can be used to provide bullet-proof protection, as described herein. Such blinds, although they may use hanging panels, can still provide ballistic projective protection by absorbing energy from a bullet or other projectile. Such a device may be comprised of a plurality of panels made of a ballistic material. Acceptable materials may include a high-density polymer (e.g., polyethylene, Tensylon), ceramic, metal (e.g., steel, titanium, and alloys thereof), aramid fiber (e.g., Kevlar), polycarbonate (e.g., Lexan), fiberglass (ArmorCore, see www.armorcore.com), carbon fibers, and other carbon structures, boron treated cloth, etc. and combinations thereof. Ballistic cloths can be used for such panels, such as by laminating such cloths, with or without other materials.
The blinds can be made with slats in more than one thickness. For example, two different thicknesses including ¼ inch or ½ inch thick slats may be provided. The blinds might have slats with a width of 3 inches, among other widths, as desired. The blinds can overlap (e.g., when closed) more for additional support and protection, and may include structure to enhance structural strength. Different types of cord for the panels to hang from, including exotic fibers such as boron and composite fiber, can be utilized. The blinds could fasten at the bottom or sides for additional strength and stability.
As examples, slats made from ArmorCore can be provided of dimensions 2″×36″×0.35″ (weight=1.9 lbs./slat) Slats made from Tensylon can be provided of dimensions 2″×36″×0.23″ (Total weight=0.6 lbs./slat).
Shades can be provided that are of a uniform material that don't use slats, but instead use one or more uniform layers of ballistic material, which may or may not be laminated, and may even be formed into panels or slats. Such shades can drop automatically, as described herein for the blinds. The shades may be opaque (blackout shades), or somewhat transparent (translucent) or totally transparent, or otherwise have small or large gaps to let light through, as desired. Multiple layers of material can be used in the shades, and the shades may be used in combination with the blinds to add extra protection. For example, the shade may automatically deploy (drop) when a ballistic event is detected, while blinds may automatically close (such as by rotating the slats).
A weight bar 615 can be used to weigh the blind 610 to aid in deployment, if desired. If desired, this weight 615 can be made of a magnetic material to be held in place by a magnet or electromagnet 617 provided on a window sill or floor or wall, such that the electromagnet is activated when a security situation is detected or otherwise triggered to better secure the blind 610 in place and improve its anti-ballistic performance. For power outages, the electromagnet may be battery powered, and only activated during as security event. Alternatively, a mechanical or electrical latch could be used for this purpose.
Alternatively, rather than a motor, the drive system 630 may utilize electromagnets or solenoids or pneumatic or hydraulic devices to retract and/or release the blind. For example, electromagnets may be used to hold the blind in a retracted position, for deployment during a security event by powering down the electromagnet when deactivated either by automated or manual means (as described herein), or by power outage, in which case the blinds, which can be weighted, can automatically deploy.
In contrast, a fixed barrier might be deployed within the door body panels, or other hollow body locations, that is permanently deployed within the door and attached to the door frame to add anti-ballistic properties to the body of the door. Such a barrier might have the upper portion attached to the door frame but hang freely within the door panels within free space in the door to provide the benefits of such a structure as described herein. The barrier would then absorb the energy of a projectile as described above. Such a barrier could be installed during manufacture of the vehicle, or might be provided as an after-market installation to add anti-ballistic properties to existing vehicles. The window blinds might also be added at the factory or as an after-market add-on.
For example, the flexible barrier in, say, a 3.5 inch door cavity takes up about ¼ inch to 1 inch of the overall space. The shock wave that goes across the material from the projectile dissipates the energy through and across the whole piece of material rather than just a small area directly around the projectile when the material is affixed to the strike face of the door. The shock wave dissipates the energy more efficiently through the material than would a fixed barrier.
Other options for use in vehicle door panels and other hollow bodies include inflatable bags that can fill with an anti-ballistic gel, sand, balls or other material to provide anti-ballistic protection. Airbag type devices might also be provided that deploy outside of the body panels to protect individuals inside the vehicle, where such airbags might be comprised of anti-ballistic inflatable sheets as discussed herein or filled with anti-ballistic material such as a gel. Such systems may be automatically or manually deployed, or permanently deployed, all of which is discussed herein and in the parent applications for various barrier embodiments.
Note that for some applications, the beads may be deployed permanently between the panes of glass, or anywhere else that ballistic protection is desired, including in hard-to-reach areas such as in doors or walls. The beads may be small and light enough to be deployed by using a pump or fan to blow the beads in place, and/or to remove them.
The beads can be comprised of any of the materials described herein, including ceramic materials or carbon fiber materials which may be particularly applicable for this purpose.
The blinds or shades can be utilized in automotive applications, such as currently blinds that are provided in some vehicles, such as in limousines or luxury vehicles, for example.
Note that anti-ballistic sheets might be used to provide protection in door and other body panels or other cavities. Alternatively or additionally, air bags constructed of anti-ballistic material (see discussion below regarding
The blind could be deployed in a manner similar to that discussed above with respect to other blinds, and these vehicle blinds might also have adjustable blades/louvers, which can have a groove that runs the length of the louver. This groove or notch can allow the louvers to interlock for additional strength. With either the home/commercial application or the automotive application the blinds can be electronic and close automatically when gunfire is sensed. The front windshield one could close partially or slowly according to the speed of the vehicle. The blinds could have fasteners that allow them to interlock. The blinds could also engage with the window sill for added strength. There could also be 2 or more layers of blinds depending on the threat. This would also allow light in but keep bullets out.
Such blinds may be deployed in school buses, public transportation (busses, trains, trolleys, taxis, even planes, for example) to protect children or other members of the public in battlefield areas or in dangerous cities or sections of cities, for example. Schools and other public buildings could be provided with such blinds, for example.
The blinds could be used to retrofit existing vehicle blinds that do not have bullet-proof or other ballistic features, or they could be installed as original equipment or as after-market add-ons.
The vehicle blinds could be configured to vibrate at a random or constant rate, as described above, to prevent an interferometers or vibration sensing listening devices from working through the blinds, avoiding eavesdropping or other spying activities. Vibration can be applied to the blinds through use of motors or piezo devices in a manner known in the art to create vibrations. Such blinds may be ideal for board rooms or military planning rooms to avoid spying operations.
Note that blinds that are constructed of ceramic or composite ballistic material can be much lighter and cheaper to build than blinds that use metallic materials, such as steel, for example, and they could prove flexible and more deployable and retractable.
Blinds using fabric and/or panels held together by fabric can be utilized. Also having blinds in a horizontal or vertical position. Closing and opening from all possible sides can be provided, e.g., from the top or bottom or left or right. Also a combination of these approaches can be used. Blinds could close from both sides. Or close from the top and bottom where each blind half covers half of a particular window.
Roll down fabric blinds using ballistic materials that come down from the top, such as that can be quickly deployed can prove useful. Also panels that fold down from the top can be utilized.
Ballistic resistant panels can be provided with the ballistic material provided on back of an ornamental design (e.g., wooden slats), or between ornamental designs, so that the blinds provide traditional ornamental aesthetics. The ballistic materials may be woven into a layered cloth that can be attached, glued, or otherwise combined with the ornamental panels to achieve the desired effect. A string or rope made of the ballistic material can be used to replace the string/rope that may be utilized in existing blind applications.
For example,
For example, 18 plies of woven Kevlar fabric such as a 600d Kevlar KM2 Plus, 24×24 square yarns per inch, plain weave construction, polyester stitching yarn, 75 denier textured yarn with a stitch pattern from a linear chain stitch (machine direction), 3.5 gage spacing or 0.75 inch spacing.
Sheets of material of the blinds, or individual slats, may have the individual fabric sheets bound by using a glue or substance around a perimeter of the sheets or a pair of edges to hold the sheets together, but let the layers remain unbound in an interior portion.
The laminated material of
Alternatively, tensylon slats can be used for the venetian style blinds. As an alternative, a thin layer of steel as a strike face can be provided on the slats to improve the anti-ballistic properties. Tensylon slats, with or without the steel surface layer, can slide in pockets on the kevlar fabric blinds to add further protection, such as in solid sheets that are rolled up when retracted and unrolled when deployed, as described hereinabove. Such blinds re flexible and lightweight, and could be designed to level 4 protection to stop rifle rounds.
For vertical blinds such as shown in
Ballistic blinds might also be arranged in a manner similar to drapes, where ballistic fabric is used to form the bullet proof drapes. In this case, the drapes can be deployed in a manner similar to fabric drapes. Vertical slats can be used in such approaches as well, where the slats fold together when the “drapes” are withdrawn (opened), and unfold when the “drapes” are deployed (closed).
Note that blinds could also be installed in the interior of rooms or against walls with the structures being installed at the ceiling or above a drop ceiling, so that the blinds can be dropped when needed for protecting a wall or room. Automatic deployment can occur as discussed above for window blinds. It has been found that free-hanging blinds can actually perform better than blinds that are secured at the bottom or sides, likely due to better energy dissipation properties when the blind is permitted to move upon impact with a bullet or shrapnel. Hence, blinds without being secured at the bottom and sides are of particular interest and make up some preferred embodiments, although a weight may be used on the bottom edge of the blinds to aid in deployment.
An alternative blind design could utilize thin layers of glass with graphene centers or Lexan between two layers of glass that may be transparent or translucent sheets or slats. A transparent or translucent anti-ballistic gel might also be used, such as shear thickening fluids that are transparent to fill the gaps between window panes or layers of glass. Some of these materials harden upon impact and might be comprised of non-Newtonian fluids that that thicken in response to force (such as mixtures of cornstarch and water do). Examples of such materials have been disclosed recently but their composition are trade secrets. See www.sciencealert.com/liquid-armour-is-now-a-thing-and-it-stops-bullets-better-than-kevlar and www.telegraph.co.uk/news/uknews/defence/4862103/Military-to-use-new-gel-that-stops-bullets.html for examples.
It is desirable that the blinds meet NIJ level IIIA standards or above. Large sheets of material can be formed which are then water jet cut to 2.5″×36″ strips of material out of the larger sheets for slats, for example.
Many other example embodiments can be provided through various combinations of the above described features. Although the embodiments described hereinabove use specific examples and alternatives, it will be understood by those skilled in the art that various additional alternatives may be used and equivalents may be substituted for elements and/or steps described herein, without necessarily deviating from the intended scope of the application. Modifications may be necessary to adapt the embodiments to a particular situation or to particular needs without departing from the intended scope of the application. It is intended that the application not be limited to the particular example implementations and example embodiments described herein, but that the claims be given their broadest reasonable interpretation to cover all novel and non-obvious embodiments, literal or equivalent, disclosed or not, covered thereby.
