Various aspects of the present disclosure relate to an entry door barricade that can be quickly and effortlessly deployed to barricade an entry door. The entry door barricade can also be quickly and effortlessly removed to allow opening of the entry door, e.g., when the user no longer intends to barricade the entry door.
When outbreaks of violence at buildings such as schools, government offices, businesses, and other occupied locations occur, potential victims located within buildings and/or interior rooms have little time to react in defense of their lives. Such outbreaks pose particular challenges to making provision for the security of occupied rooms because building design specifications, codes, regulations and laws focus on minimum safety goals rather than security considerations. For instance, typical safety goals focus on the types of safety concerns that arise in response to non-manmade issues. As such, security considerations that focus on acts that lead to intentional human violence are largely unaddressed. By way of example, as a result of the vulnerability inherent to many door designs, perpetrators of violent acts have easily moved through hallways and into rooms during the implementation of their of nefarious and heinous acts of violence.
According to various aspects of the present disclosure, an entry door barricade is provided, which is deployed to temporarily hold a door shut against a corresponding doorframe. The entry door barricade comprises an elongate bar and a channel lock. The elongate bar has a major length, which may be at least as long as a span between opposing jams of the doorframe to which the entry door barricade is to be deployed. The channel lock has an extension member and a bar grasping member that extends out from the extension member. When the entry door barricade is used to temporarily hold the door shut against the corresponding doorframe, the elongate bar is positioned between a surface of the door and the bar grasping member of the channel lock. Here, the surface of the door faces the inside of the room or other area to be barricaded (and is thus referred to herein as an “inside” surface of the door). The channel lock also engages at least one of the doorframe and the door such that the extension member of the channel lock extends under the door.
For instance, the channel lock may further comprise a door grasping member such that the extension member spans between the door grasping member and the bar grasping member. Under this configuration, when the entry door barricade is used to temporarily hold the door shut against the corresponding doorframe, the door grasping member of the channel lock is positioned adjacent to a surface of the door facing outside the room or other area to be barricaded (and is thus referred to herein as an “outside” surface of the door). Moreover, the door sits over the extension member of the channel lock and the elongate bar is positioned between an inside surface of the door and the bar grasping member of the channel lock. This configuration is particularly well suited for an outward swinging door.
As another example, the extension member of the channel lock may comprise a plate having a notch therein to receive a soffit of the corresponding doorframe. Under this configuration, when the entry door barricade is used to temporarily hold the door shut against the corresponding doorframe, the door sits over the plate of the channel lock, the notch of the plate is received in the soffit of the corresponding doorframe, and the elongate bar is positioned between the inside surface of the door and the bar grasping member of the channel lock. This configuration is particularly well suited for an inward swinging door.
According to further aspects of the present disclosure, an entry door barricade is provided to temporarily hold a pair of doors shut against a corresponding doorframe. The entry door barricade comprises an elongate bar having a major length and a channel lock having an extension member that spans between a door grasping member and a bar grasping member. The elongate bar and channel lock are configured such that when positioned relative to a first door and a second door in a double door entryway and both the first door and the second door are closed against the doorframe, the extension member of the channel lock extends under both the first and second doors. Also, the door grasping member of the channel lock contacts an outside surface of each of the first and second doors. Moreover, the elongate bar is positioned between an inside surface of each of the first and second doors, and the bar grasping member of the channel lock.
According to yet further aspects of the present disclosure, an entry door barricade is provided to temporarily hold a pair of doors shut against a corresponding doorframe. The entry door barricade comprises an elongate bar having a major length, a first channel lock and a second channel lock. The first channel lock has an extension member that spans between a door grasping member and bar grasping member. Likewise, the second channel lock has an extension member that spans between a door grasping member and bar grasping member. The elongate bar, the first channel lock and the second channel lock are configured such that when positioned relative to a first door and a second door in a double door entryway and both the first door and the second door are closed against the doorframe, the extension member of the first channel lock extends under the first door.
Also, the extension member of the second channel lock extends under the second door. Additionally, the door grasping member of the first channel lock contacts an outside surface of the first door, and the door grasping member of the second channel lock contacts an outside surface of the second door. Yet further, the elongate bar is positioned between an inside surface of each of the first and second doors on a first side of the elongate bar, and the bar grasping member of the first channel lock and the bar grasping member of the second channel lock on a second side of the elongate bar opposite the first side of the elongate bar.
Various aspects of the present disclosure provide a universal entry door barricade that is capable of being deployed in seconds to temporarily barricade a door, thus preventing the door from being opened. Likewise, the entry door barricade can be quickly and easily removed from engagement with a door, e.g., when the user no longer intends to barricade the door, thus allowing normal operation of the door for ingress or egress. The entry door barricade herein is configurable to accommodate both inward and outward swinging doors and requires no modification to the existing door structure. Moreover no modification is required to the area surrounding the door. Still further, the entry door barricade is simple in construction, light weight and can be used by persons of all ages without the use or need for tools, keys, special knowledge, or significant effort.
Referring to the drawings and in particular to
The elongate bar 12 is a rigid structure that extends along a major length, e.g., the X dimension in
The major length of the elongate bar 12 is typically at least as long as a span between opposing jams of a corresponding doorframe. Thus, the elongate bar 12 may be at least 28 inches (71.12 centimeters) long. For instance, entry doors may range from about 30 inches (76.2 centimeters) to about 38 inches (97.52 centimeters) wide. As such, the length of the elongate bar 12 can match or exceed the width of the door to which the elongate bar 12 is designed to barricade. However, in practice, other dimensions may be utilized, e.g., depending upon the features of a doorway for which the entry door barricade 10 is intended.
As a working example, a commercial entry door may be about 38 inches (97.52 centimeters) wide. In this working example, the elongate bar 12 is at least 38 inches long (97.52 centimeters) long (in the X dimension). As a further example, the elongate bar 12 may have a cross-section of 1.5 inches (3.81 centimeters) in the Y dimension by 1.5 inches (3.81 centimeters) in the Z dimension.
In the illustrative example, the channel lock 14 is implemented as a “trough-shaped” (e.g., generally U-shaped) channel member. For instance, the channel lock 14 may be bent from a single piece of material, e.g., ASTM A36 Carbon Steel. The channel lock 14 includes an extension member 16 (seen in the X-Y plane) that spans between a door grasping member 18 (seen in the X-Z plane), and a bar grasping member 19 (also seen in the X-Z plane). The extension member 16 has a major surface 16A that projects outward perpendicular to the elongate bar 12 as illustrated. The door grasping member 18 extends upward from a first end of the extension member 16 and the bar grasping member 19 extends upward from a second end of the extension member 16 opposite the first end.
In the above-working example, the extension member 16 is approximately 4-½ inches (about 11.43 centimeters) long along the X dimension. The depth of the extension member 16 in the direction away from the elongate bar 12 (along the Y dimension) will vary depending upon the door and doorframe configuration. Correspondingly, the door grasping member 18 is approximately 4-½ inches (about 11.43 centimeters) long along the X dimension and approximately 1 inch (about 2.54 centimeters) tall along the Z dimension. Similarly, the bar grasping member 19 is approximately 4-½ inches (about 11.43 centimeters) long along the X dimension and approximately 1 inch (about 2.54 centimeters) tall along the Z dimension. However, the dimensions of the extension member 16 will ultimately vary based upon a number of factors, such as the size of the door, the configuration of the doorframe, and the holding strength required by the particular application.
The door grasping member 18 is illustrated as having a length (along the X dimension) that is the same as the corresponding length of the extension member 16. However, in practice, the length of the door grasping member 18 may alternatively be larger or smaller than the length of the extension member 16 (an example of this is set out with regard to
During use, the channel lock 14 extends from the elongate bar 12 in a direction perpendicular to the major length of the elongate bar 12. Thus, for instance, in
The entry door barricade 10 may also include other features. For instance, in illustrative implementations, the elongate bar 12 and the channel lock 14 are handled separately until set up to barricade a door. As such, the entry door barricade 10 may include a first handle 20 that attaches to the top of the elongate bar 12 to make it easy to wield the elongate bar 12. For example, as illustrated in
The entry door barricade 10 may also include a second handle 22 that attaches to the back side of the bar grasping member 19 of the channel lock 14. The second handle 22 is provided to make it easy to wield the channel lock 14 independent of the elongate bar 12. Thus, in
Referring to
Notably, the major surface 16B of the extension member 16 portion of the channel lock 14 is not rectangular. Rather, the major surface 16B includes a flared out portion. For instance, the extension member 16 may comprise at least one projection such that a major surface 16B of the extension member 16 is not rectangular. The flared out portion (e.g., projection) can be used to grab a door jam or create interference with a soffit so as to provide resistance to door entry by securing to both the door and the door frame, as will be described in greater detail herein.
Also, the channel lock 12 includes a stop member 21 that extends from the bar grasping member 19. For instance, the stop member 21 may be implemented as a strike plate that extends from the bar grasping member 19 such that when the entry door barricade 10 is deployed to barricade the door, the strike plate extends over the top of the elongate bar 12. The strike plate may be formed by making approximately a 90 degree bend in the base material used to make the channel lock 14.
The implementation of the entry door barricade 10 of
Thus, when the entry door barricade 10 is used to temporarily hold the door shut against the corresponding doorframe, the door grasping member 18 of the channel lock 14 is positioned adjacent to a surface of the door facing outside a room or other area to be barricaded (and is thus referred to herein as an “outside” surface of the door). Also, the door sits over the extension member 16 of the channel lock 14. Still further, the elongate bar is positioned between a surface of the door facing inside the room or other area to be barricaded (and is thus referred to herein as an “inside” surface of the door), and the bar grasping member 19 of the channel lock 14. In this manner, the channel lock 14 is prevented from sliding lengthwise along the major axis of the elongate bar 12 based upon contact between an abutment surface of the stop bar 21 and the limiter 23.
Where the elongate bar 12 includes both limiters 23, 25, the user can engage the elongate bar 12 in two different orientations for ease of use, i.e., the user can flip the elongate bar 12 around so that the stop member 21 of the channel lock 14 engages the limiter 25, if desired. Regardless, the limiter (e.g., limiter 23) in engagement with the abutment surface of the strike plate (stop member 21), prevents the channel lock 14 from sliding along the elongate bar 12, thus securing the channel lock 14 in a desired position, proximate to one end of the elongate bar 12.
Also, as illustrated, a single handle 22 is provided. The handle 22 is on the channel lock 14, although other configurations may be implemented.

In practice, there is likely to be some variability from door to door. As such, a spacer 25 can be installed to act as a shim. The spacer 25 couples between the elongate bar 12 and the channel lock 14 when the entry door barricade 10 is used to temporarily hold a door shut against a corresponding doorframe, to adjust a distance that the channel lock 14 extends from the elongate bar 12. The thickness of the spacer 25 thus serves to ensure a snug fit between the elongate bar and the channel lock 14 when used to hold a corresponding door closed. Moreover, when the channel lock 14 is installed in cooperation with the elongate bar 12 in a doorway, movement by the channel lock 14 along the length of the elongate bar 12 is restricted in part due to friction that is created by the spacer 25.
As illustrated, the spacer 25 includes a projection that is received in (e.g., snaps in, compresses in, slides in, etc.) the channel 24B. As such, the spacer 25 can be installed, relocated, swapped out for a different spacer 25 of different thickness, etc., in a quick and efficient manner. However, other techniques can be utilized to add a shim/spacer as required by a particular application. Optionally, a spacer 25 can also be positioned on a side of the elongate bar 12 facing the inside surface of the door, e.g., by positioning the spacer 25 in the channel 24D. Still further, multiple spacers 25 can be used, e.g., a first spacer in the channel 24B and a second spacer in the channel 24D.

According to illustrative examples, when the entry door barricade 10 is deployed, the elongate bar 12 has a major length that extends a length at least as long as a span between opposing jams of the doorframe 40. In this regard, the ends of the elongate bar 12 are seated within the doorframe 40 such that the elongate bar 12 abuts a “stop” of the soffit 48 on both the hinge jam 42 and the strike jam 46.
The channel lock 14 is dimensioned to extend from the elongate bar 12 in a direction perpendicular to the major length of the elongate bar 12 and in the direction of the door 32 such that when the elongate bar 12 is positioned relative to the doorframe 40 (e.g., between the hinge jam and strike jam) and the door 32 is closed against the doorframe 40, and the extension member 16 of the channel lock 14 extends under the door 32 to the opposite side of the door relative to the elongate bar. Here, the elongate bar 12 is further positioned between an inside surface of the door 32 and the bar grasping member 19 of the channel lock 14. As such, there may be a “snug” fit between the elongate bar 12, the channel lock 14 and the door 32.

With reference to the previous FIGURES generally, in operation, a user, e.g., a classroom teacher in a crisis situation (such as the presence of an unauthorized or violent intruder in a school), grabs the components of the entry door barricade 10. The elongate bar 12 is detached from the channel lock 14 until brought into cooperation to hold the door 32 shut against the doorframe 40. As such, the user pushes open the door slightly and slips the channel lock 14 under the door 32, then pulls the door 32 shut. For instance, the user can grasp the handle 22 to easily wield the channel lock 14.
Once the door 32 is pulled shut, the user drops the elongate bar 12 down into the channel lock 14. For instance, the user can wield the elongate bar 12 using the handle 20 or otherwise grasp the elongate bar along its length. As such, the elongate bar 12 is positioned between the hinge jam 42 and the strike jam 46, and engages the stop surface 48A of the soffit 48. Moreover, the elongate bar 12 is wedged between the bar grasping member 19 of the channel lock 14 and the inside surface of the door 32. In the event that an assailant armed with a firearm or someone else try to enter while the entry door barricade 10 is in place, any attempts to pull on the door 32 will result in the door 32 failing to open because the channel lock 14 cooperates with the elongate bar 12 and the soffit 48 to prevent the door from swinging open.
However, if an emergency situation arises, the entry door barricade 10 can be quickly removed from the inside to allow the door to open, e.g., to allow an innocent party otherwise trapped in a hallway or other exterior location to enter through the doorway before the entry door barricade 10 is quickly redeployed as described above. For instance, the user lifts the elongate bar 12, e.g., by grasping the handle 20, and lifting upward. The door 32 can be opened while the channel lock 14 remains under the door 32. After the door is re-closed, the user drops the elongate bar 12 back into the channel lock 14 as described above.
The ability to quickly remove the entry door barricade 10 by lifting the elongate bar 12 out of the channel lock 14, e.g., by grasping the handle 20 and lifting upward, permits individuals to quickly open the door 32 once rapidly changing circumstances drive a decision or need to evacuate a secured location.
The entry door barricade 10 is durable and robust against attempts to disable the device through the use of weapons and hand tools. The entry door barricade 10 is even bullet resistant. In a working example, analysis results indicate a force well in excess of 1,000 pounds has been found to be required to compromise example implementations of the entry door barricade 10. This is significantly more force than a typical assailant is capable of producing. Moreover, in illustrative examples, even attempts to shoot out the entry door barricade 10 will result in the assailant wasting time and effort to gain access to the room. For instance, an exemplary implementation has been tested and found with withstand gunshots from 9 mm (millimeter), 0.223 and 12 gauge caliber weapons. In this regard, the selection of the material for the channel lock 14 and the X shape design of the elongate bar 12 allows the entry door barricade 10 to withstand multiple penetrating blows, e.g., via gunshot, without completely compromising the structural integrity of the entry door barricade 10 and its ability to hold a door in its secure position.
