The present invention relates to glazing protections systems and, more specifically, to a glazing protections system that protects display case glass.
Display cases are typically used to display expensive items, such as jewelry, in retail stores. As shown in
Since glass can be brittle, dropping heavy objects on the glass can cause it to shatter. Also, “smash-and-grab” robberies have become more frequent in recent years. In such a robbery, a perpetrator will shatter one of the glass sheets with a hammer or other such object and then will reach in the display case to remove the items inside.
Attempts have been made to cover display cases with transparent sheets of plastic to protect the glass. However, common plastics, such as acrylic sheets tend to scratch easily and give the display a cheaper look, which makes items such as jewelry look less desirable to potential consumers. Smash resistant window films have also been tried. While the decrease the likelihood of a glass sheet shattering, they give only limited protection and can be easily cut away with a sharp instrument.
Therefore, there is a need for a display case protection system that appears like glass, but that resists shattering even when hit with objects like sledge hammers.
The disadvantages of the prior art are overcome by the present invention which, in one aspect, is a display case shield for protecting a display case having a frame that supports a first glazing and a second glazing that is transverse to the first glazing. A smash-resistant plastic sheet is bent to include at least one angle between a first portion that covers the first glazing and a second portion that covers the second glazing. An anchoring system secures the smash-resistant plastic sheet to the display case.
In another aspect, the invention is a display shield for protecting a display case having a frame that supports a first glazing and a second glazing that is transverse to the first glazing. A polycarbonate smash-resistant plastic sheet is bent to include at least one angle between a first portion that covers the first glazing and a second portion that covers the second glazing. The polycarbonate smash-resistant plastic sheet defines a linear notch separating the first portion from the second portion. A first anchor secures a first end of the polycarbonate smash-resistant plastic sheet to the display case. The first anchor includes a first L-shaped strip having a first surface disposed along the first end of the polycarbonate smash-resistant plastic sheet and a second surface disposed along a first edge of the frame; a first fastener that fastens the first surface of the L-shaped strip and the first end of the polycarbonate smash-resistant plastic sheet to a first face of the frame; and a second fastener that fastens the second surface of the L-shaped strip to a second face of the frame. A second anchor secures a second end, disposed oppositely from the first end, of the polycarbonate smash-resistant plastic sheet to the display case. The second anchor includes a second L-shaped strip having a third surface disposed along the second end of the polycarbonate smash-resistant plastic sheet and a fourth surface disposed along a second edge of the frame; a third fastener that fastens the third surface of the L-shaped strip and the second end of the polycarbonate smash-resistant plastic sheet to a third face of the frame; and a fourth fastener that fastens the fourth surface of the L-shaped strip to a fourth face of the frame. A first strip of very high bond tape is adhered to both the first surface of the L-shaped strip and to the polycarbonate smash-resistant plastic sheet. A second strip of very high bond tape is adhered to both the second surface of the L-shaped strip and to the frame.
In yet another aspect, the invention is a method of protecting a display case having a frame that supports a first glazing and a second glazing that is at an angular relationship to the first glazing, in which a linear notch is cut in a selected surface of a polycarbonate sheet so as to separate a first portion that corresponds in size to the first glazing and a second portion that corresponds in size to the second glazing. The polycarbonate sheet is cold bended along the linear notch so that the first portion is at an angular relationship that corresponds to the angular relationship between the first glazing and the second glazing. The polycarbonate sheet is secured to the display case after the cold bending step.
These and other aspects of the invention will become apparent from the following description of the preferred embodiments taken in conjunction with the following drawings. As would be obvious to one skilled in the art, many variations and modifications of the invention may be effected without departing from the spirit and scope of the novel concepts of the disclosure.
A preferred embodiment of the invention is now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. Unless otherwise specifically indicated in the disclosure that follows, the drawings are not necessarily drawn to scale. The present disclosure should in no way be limited to the exemplary implementations and techniques illustrated in the drawings and described below. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of “a,” “an,” and “the” includes plural reference, the meaning of “in” includes “in” and “on.”
As shown in
Generally, heating a polycarbonate sheet to facilitate bending it will result in discoloration and distortion. Therefore, to ensure that the smash-resistant plastic sheet 110 is clear, it is bent using a cold bending process. As shown in
One embodiment of the anchoring system, as shown in
A first strip of two-sided very high bond tape 162 can be adhered to both the first surface 142 of the first L-shaped strip 140 and to the smash-resistant plastic sheet 110 and a second strip of very high bond tape 162 can be adhered to both the second surface 144 of the L-shaped strip 140 and to the frame 12. Similarly, a third strip of very high bond tape 162 can be adhered to both the third surface 176 of the second L-shaped strip 170 and to the smash-resistant plastic sheet 110 and a fourth strip of very high bond tape 162 can be adhered to both the fourth surface of the L-shaped strip 170 and to the frame 12. Also, a first impact equalization bond material 168 can be placed under the first anchor 122 between a first portion of the smash-resistant plastic sheet 110 and the first glazing 22 and a second impact equalization bond material 168 can be placed under the second anchor 124 and between a second portion of the smash-resistant plastic sheet 110 and the second glazing 24.
Although specific advantages have been enumerated above, various embodiments may include some, none, or all of the enumerated advantages. Other technical advantages may become readily apparent to one of ordinary skill in the art after review of the following figures and description. It is understood that, although exemplary embodiments are illustrated in the figures and described below, the principles of the present disclosure may be implemented using any number of techniques, whether currently known or not. Modifications, additions, or omissions may be made to the systems, apparatuses, and methods described herein without departing from the scope of the invention. The components of the systems and apparatuses may be integrated or separated. The operations of the systems and apparatuses disclosed herein may be performed by more, fewer, or other components and the methods described may include more, fewer, or other steps. Additionally, steps may be performed in any suitable order. As used in this document, “each” refers to each member of a set or each member of a subset of a set. It is intended that the claims and claim elements recited below do not invoke 35 U.S.C. § 112(f) unless the words “means for” or “step for” are explicitly used in the particular claim. The above-described embodiments, while including the preferred embodiment and the best mode of the invention known to the inventor at the time of filing, are given as illustrative examples only. It will be readily appreciated that many deviations may be made from the specific embodiments disclosed in this specification without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is to be determined by the claims below rather than being limited to the specifically described embodiments above.
