The present invention relates generally to an apparatus for obstructing the view of an individual. More specifically, the present invention is a deployable vision obstructer that is attached to a door above a door window, to be used specifically during a lockdown drill or procedure.
Public acts of violence unfortunately occur with some frequency, especially in educational environments where academic or peer stress can play a role in an individual's mental state. Measures can be taken in an attempt to reduce or discourage violent acts, such as using metal detectors or personal searches, however, many of the measures taken are not always applicable to other situations or are not infallible. While much effort is put into the prevention of such violent incidences, the reality is that such events still occur. As a result, many institutions practice lockdown drills in an attempt to be prepared for potential life threatening situations. During these drills, individuals are told to remain in the room they are currently in and lock the door. Many of the doors in schools and other institutions have windows that allow the perpetrator to peer inside, allowing them to locate individuals on which they can inflict harm. One of the best ways to prevent a perpetrator from attacking is to block his or her view from the person or object to which the perpetrator intends to inflict harm. If the perpetrator is unaware of the presence of an individual, then the chances of the perpetrator inflicting harm on the given individual are greatly lowered. Additionally, the doors for certain rooms are not always easily locked, especially if the door requires a key and in an emergency situation time is undoubtedly important.
Therefore it is the object of the present invention to provide an apparatus for obstructing an individual's view during lockdown drills and procedures. The present invention is a deployable vision obstructer that is attached to a door surface above a door window. The deployable vision obstructer includes a flexible shade that is opaque and is configurable between a retracted position and a deployed position. The flexible shade is attached to the door surface by means of a mounting assembly being a pair of opposing hook and loop fasteners. When in the retracted position, the flexible shade is rolled above the door window, such that the door window is unobstructed, and is held in place by a shade retaining assembly. When in the deployed position, the flexible shade extends down below the door window, such that the door window is obstructed. A security key for locking the door is also coupled to the flexible shade and is accessible when the flexible shade is in the deployed position.
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
The present invention is a deployable vision obstructer specifically for use during lockdown drills and procedures. The deployable vision obstructer comprises a flexible shade 10, a shade retaining assembly 20, a mounting assembly 30, and a security key 40. The flexible shade 10 is an opaque piece of material that is used to obstruct the view of an individual. The flexible shade 10 is designed to be used on an as needed basis and thus is configurable between a retracted position, shown in

In the preferred embodiment of the present invention, the first fastener 21 is a lashing hook 26 and the second fastener 25 is a cord 22. The cord 22 comprises a first end 23 and a second end 24, wherein the first end 23 and the second end 24 are positioned opposite each other along the cord 22. The first end 23 and the second are sewn to the proximal surface 13, such that the cord 22 is positioned in between the flexible shade 10 and the door surface 70, when the flexible shade 10 is attached to the door surface 70. The lashing hook 26 is riveted to the distal surface 14, such that the lashing hook 26 protrudes away from the door. When the flexible shade 10 is rolled upwards into the retracted position, the cord 22 is traversed around the flexible shade 10 and coupled to the lashing hook 26, wherein the flexible shade 10 is retained in the retracted position.

In the preferred embodiment of the present invention, the deployable vision obstructer is constructed in the following manner. The flexible shade 10 is cut from a piece of fabric according to the dimensions of the window for which the flexible shade 10 is intended to cover. Each edge of the flexible shade 10 is then stitched using a four-thread overlock stitch, or similar stitch, in order to reinforce the edges of the flexible shade 10 while allowing the flexible shade 10 to maintain flexibility. A portion of the two sides perpendicular to the proximal end 11 and the distal end 12 are then folded over and are straight stitched from the proximal end 11 to the distal end 12 forming a first folded edge and second folded edge. The first weight 51 and the second weight 52 are then stitched to opposing corners on the proximal surface 13, such that a bottom section of material remains below the first weight 51 and the second weight 52 along the distal end 12. The bottom section of material is then folded over the first weight 51 and the second weight 52 and stitched to the proximal surface 13 along the distal end 12. The aperture 15 is then cut through the distal end 12 and the grommet 16 is positioned through the aperture 15 and connected to the flexible shade 10. A top section of material along the proximal end 11 is then folded over towards the proximal surface 13 and stitched to the proximal surface 13 along the proximal end 11. The lashing hook 26 is then riveted to the distal surface 14 along the proximal end 11, while the first end 23 and the second end 24 of the cord 22 are sewn to the proximal surface 13 along the proximal end 11. The first fastening strip 31 is then stitched to the top section of material, along the proximal edge. Finally, the lanyard 60 is looped through the grommet 16 and the security key 40 is attached to the lanyard 60. While the above describes the preferred method of constructing the present invention, it is possible for the deployable vision obstructer to be constructed in any number of similar ways.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
