DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

(8) For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.

(9) Referring now to FIG. 1, a removable bullet resistant protective shield 100 is shown according to one embodiment of the present invention. The entire desk is not depicted in the figures, but FIG. 1 does depict a desktop 102 shown supported by a standard desk frame 103. It is noted that the present invention in its various embodiments is capable of being adapted for use with a variety of desk styles. It is also noted that while in a typical scholastic setting a desk would either generally be a standalone desk and chair, a multi-student desk and chairs, a frame styled desk or a storage styled desk, the term desk as used herein is not intended to be limited any particular style. Rather, the present invention could be utilized with numerous desk styles having a substantially planar work surface to which the bullet resistant protective shield can be affixed.

(10) In the illustrated embodiments, the bullet resistant protective shield 100 is affixed to the desktop 102 with a channel coupling 104. The bullet resistant protective shield 100 is a projectile resistant material. Known projectile resistant materials suitable for use with the present invention include but are not limited to ultra-high molecular weight polyethylene, bullet-resistant glass, polycarbonates (including specialized scratch resistant polycarbonates), polyurethane, fiberglass and resins alone or in combination. Bullet resistant protective shield 100 can also be made of conventional desktop materials equipped with protective interlayers and protective films.

(11) The channel coupling 104 can comprise two elements: a bullet resistant protective shield coupling 106 and a desktop coupling 108. The bullet resistant protective shield coupling 106 features a coupling edge 110 and a coupling channel 112. The desktop coupling 108 also features a coupling edge 114 and a coupling channel 116. It is noted that the coupling channel 116 as depicted in FIG. 1 is formed by an inner surface 124 of the coupling edge 114 and an outer surface of the desktop edge 126. However, as discussed further below, channels 112 and 116 could be formed in other ways. Bullet resistant protective shield coupling 106 can be secured to bullet resistant protective shield 100 by a variety of fastening mechanisms 118. In the illustrated embodiment, fastening mechanism 118 is a screw through a connection element of the coupling 106 but could be various other attachment means including but not limited to nails, welds and adhesives alone or in combination. Similarly, desktop coupling 108 is secured to desktop 102 with a fastening mechanism 120. Again, in the illustrated embodiment, fastening mechanism 120 is a screw but could be various other attachment means including but not limited to nails, welds and adhesives alone or in combination. In FIG. 2, openings 122 are illustrated through which fastening mechanisms 118, 120 are inserted.

(12) In operation, the bullet resistant protective shield 100 would be secured to the desktop by inserting coupling edge 110 into channel 116. The relative length of coupling edge 110 and depth of channel 116 could vary from embodiment to embodiment. However, in one embodiment, it is preferred that the respective length and depth are sufficient that the bullet resistant protective shield 100 when seated does not rock or wobble back and forth. When needed, the bullet resistant protective shield 100 can be lifted thereby disengaging coupling edge 110 from channel 116 allowing bullet resistant protective shield 100 to be completely removed.

(13) In certain embodiments, bullet resistant protective shield 100 can be equipped with handles on an inside or outside surface or outer edge allowing for better user control. In FIG. 5, the top edge of the bullet resistant protective shield 100 includes grasping mechanisms 128 such as handles or knobs (FIG. 5) to aid in its removal.

(14) Referring to FIGS. 3-5, channel coupling 104 could be accomplished in a variety of ways and yet still accomplish its intended purpose. In FIG. 3, rather than utilizing an edge of the desktop, channel 116 is formed by an integrated piece that is affixed to the edge of the desktop with a fastening mechanism 120 such as a screw through a connection element of the coupling 104. For ease of discussion, such a channel 116 will be referred to as “U-shaped.” However, it is not intended to be limited to a rounded bottom but rather simply signifies that the channel 116 is formed by two substantially parallel vertical pieces flanking a bottom section. The bottom of the channel 116 could be rounded (concave or convex), V-shaped or numerous other shapes. Moreover, in the embodiments of FIGS. 1-5, the bottom of channel 116 substantially corresponds to the bottom surface of the coupling edge 110. However, in other embodiments, it is not critical that the bottom of the channel 116 match up at all with the shape of the coupling edge. Such variety in the respective shapes of channels 112, 116 and coupling edges 110, 114 can apply to all channel coupling 104 embodiments discussed herein.

(15) Again, for ease of reference, bullet resistant protective shield coupling 106 in FIG. 3 is referred to as “L-shaped,” given its cross-sectional shape. However, it is not intended to be limited to any particular angular orientation provided it has a substantially horizontal section and a substantially vertical section. In this embodiment, channel 112 is formed by coupling edge 110 and the inner surface of the bullet resistant protective shield 100. In operation, coupling edge 110 is slid into channel 116 and coupling edge 114 rests in channel 112. It is noted that channel 112 is not depicted in FIG. 3 as snugly fitting around coupling edge 114. In certain embodiments, such a fit would be acceptable. In other embodiments, a snugger fit would be preferred. Similar adaptability would apply to all channel/coupling engagements discussed herein.

(16) Referring to FIG. 4, channel coupling 104 comprises two L-shaped couplings—one affixed to the bullet resistant protective shield 100 and one affixed to the desktop. Again, L-shaped is not intended to be limited to any particular angular orientation provided it has a substantially horizontal section and a substantially vertical section.

(17) In FIG. 5, two U-shaped couplings are utilized. Again, U-shaped is not intended to be limited to a rounded bottom but rather simply signifies that the channel 112, 116 is formed by two substantially parallel vertical pieces flanking a bottom section. The bottom of the channel 112, 116 could be rounded (concave or convex), V-shaped or numerous other shapes.

(18) The channel couplings 104 discussed herein could be made of numerous materials including but not limited to aluminum, steel, plastic and combinations thereof.

(19) It is also noted that, as depicted in FIG. 6, coupling edges 114 along the desktop 102 and their corresponding coupling edges 110 on the protective shield 100 could be substantially continuous along the entire edge of the desktop 102 and protective shield 100. However, as seen in FIG. 7, in some embodiments, intermittent sections of coupling edges 114 on the desktop 102 and corresponding to intermittent coupling edges 110 on the protective shield 100 would suffice. It is also noted that in certain embodiments, intermittent coupling edges on the desktop could be used with a continuous coupling edge on the protective shield. Similarly, continuous coupling edges on the desktop could be used with intermittent coupling edges on the protective shield.

(20) It is understood that the above-described arrangements are only illustrative of the application of the basic principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention. The appended claims are intended to cover such modifications and arrangements.

(21) For example, it is noted that, as used herein, the terms vertical, substantially vertical, horizontal and substantially horizontal are intended to encompass embodiments where, for example, the coupling edge 110 is slightly angularly oriented and the receiving channel 116 is capable of receiving the coupling edge 110 at such an angle without the protective shield 100 becoming immobilized due to a poor fit. In other words, the more truly vertical the coupling edge 110 and receiving channel 116 are, the more readily one can remove the protective shield 100 when needed. Such an orientation also allows for a more substantially vertical orientation of the shield 100. Nevertheless, the invention in its various embodiments does not require strictly vertical or horizontal members in coupling the shield 100 to the desktop 102 and such variations are considered to be within the scope of the claims.
