Title: Support plate for a picture frame

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to picture frames and, more particularly, to a support plate for a picture frame. 
     In prior U.S. Pat. No. 6,780,273 (the &#39;273 Patent), a process for making a picture frame having printed border artwork on a transparent front panel that has a separately attached rear support plate is described. The support plate is created by marking a cut path in a computer for cutting the picture frame support plate and then laser cutting or die cutting a foldout picture frame stand into the support plate and cutting the support plate along the marked cut path. The cut picture frame support plate is then attached to the cut transparent front panel. The picture frame support plate may be made of a paper board or plastic and have a fold-out picture frame stand formed therein to reduce the cost of the picture frame. While this support plate does function as a low-cost frame support for a picture frame, the fold-out stand is relatively weak and easily collapses allowing the frame to fall from an upright position. Accordingly, what is needed is a more robust stand to support the frame while maintaining a low-cost product. 
     SUMMARY OF THE INVENTION 
     A backing plate for a photograph frame comprises a generally flat molded plastic sheet shaped and sized to accommodate a selected style and size of photograph frame. An integral frame stand is defined by a first pair of spaced apart lines formed in the sheet and extending from a pair of spaced apart points in the sheet to one or more edges of the sheet. The lines cut through a thickness of the sheet to create a first plastic strip separated from the sheet by the lines, but attached to the sheet at one end. A thinned linear area is defined between the pair of points at the end of the strip attached to the sheet so as to create a plastic hinge such that the first strip can be bent at an angle out of the plane of the plastic sheet. A second plastic strip is created within the first plastic strip by another pair of lines extending at a first end from a pair of spaced apart points on the first plastic strip. A second end of each of these latter pair of lines terminates in a connecting line extending partially across the first plastic strip thereby forming an end of the second strip. A thinned linear area is defined between the another pair of points such that the second plastic strip can be bent at an angle out of the plane of the plastic strip. At least one groove is formed in the plastic sheet adjacent the first strip in a location such that the second strip can be bent out of a plane of the first plastic strip and the end of the second plastic strip can be placed in the groove to support the first plastic strip at a predetermined angular orientation with respect to the plastic sheet to form a support for the backing plate. 
     In one embodiment, the backing plate is cut such that the first pair of lines define a generally hour-glass shape of the first strip such that the first strip has a narrow width portion between a pair of wider width upper and lower sections. The thinned linear area between the another pair of spaced apart points on the first plastic strip extends partially across the narrow width portion of the first plastic strip. The second plastic strip has an end at the connecting line that is wider than the narrow width portion of the first plastic strip. The at least one groove is formed in the plastic sheet adjacent the narrow width portion of the first plastic strip. The wider end of the second plastic strip is wide enough to engage the groove so as to trap the second plastic strip between the groove and the first plastic strip to thereby hold the first plastic strip in an angular orientation with respect to the plastic sheet. The first plastic strip is thereby formed to support the plastic sheet in an angular presentation position.

     DETAILED DESCRIPTION 
     Embodiments are described herein with reference to the attached figures wherein like reference numerals are used throughout the figures to designate similar or equivalent elements. The figures are not drawn to scale and they are provided merely to illustrate aspects disclosed herein. Several disclosed aspects are described below with reference to non-limiting example applications for illustration. It should be understood that numerous specific details, relationships and methods are set forth to provide a full understanding of the embodiments disclosed herein. One having ordinary skill in the relevant art, however, will readily recognize that the disclosed embodiments can be practiced without one or more of the specific details or with other methods. In other instances, well-known structures or operations are not shown in detail to avoid obscuring aspects disclosed herein. The embodiments are not limited by the illustrated ordering of acts or events, as some acts may occur in different orders and/or concurrently with other acts or events. Furthermore, not all illustrated acts or events are required to implement a methodology in accordance with the embodiments. 
     Notwithstanding that the numerical ranges and parameters setting forth the broad scope are approximations, the numerical values set forth in specific non-limiting examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Moreover, all ranges disclosed herein are to be understood to encompass any and all sub-ranges subsumed therein. For example, a range of “less than 10” can include any and all sub-ranges between (and including) the minimum value of zero and the maximum value of 10, that is, any and all sub-ranges having a minimum value of equal to or greater than zero and a maximum value of equal to or less than 10, e.g., 1 to 4. 
     Referring to the drawings,  FIGS. 1 and 2  concurrently, a substantially flat sheet  10  is shown with various cutouts and cut-lines. This sheet is used as a backing plate for a photographic frame of the type described in the &#39;273 Patent, the disclosure of which is hereby incorporated by reference. In the example described herein, the sheet is about 3 ½ inches by about 4 ½ inches although the design can be employed in any typical sized photograph frame. The sheet  10  may be formed of many different types of materials suitable for use as backing sheets for photograph frames such as, for example, compressed card stock or various types of plastic polymers, but in a preferred embodiment, the selected material for the sheet  10  is a high impact polystyrene material that is commercially available for plastic injection molding. For injection molding of the sheet  10 , the mold is formed with selected cutouts  12   a,    12   b  and  12   c . These cutouts suffice to reduce the volume of material needed to mold the sheet and therefore reduce the cost of manufacturing. Three sides of the sheet  10  are formed with a border or strip-like area  14  that is, in the illustrated embodiment, depressed away from a primary plane of the sheet  10  and serves, in one function, to strengthen the sheet and, in another function, to space the sheet away from a front portion of a frame (not shown) so as to allow space for insertion of a photograph between the backing sheet and the frame front of the type shown in the aforementioned &#39;273 Patent. 
     It should be noted that a typical thickness of material for the sheet  10  is about 1.5 MM or 1/16 inch and the border  14  is desirable in order to minimize bending of the sheet. Furthermore, the offset border  14  also functions as the contact area between the backing sheet  10  and a front decorative support plate of the type described in the &#39;273 Patent so as to create the space between the backing sheet and the front support plate for insertion of a photograph. When the backing sheet and front support plate are assembled, typically by gluing, a photograph can be inserted from the edge of the backing sheet where the border  14  is omitted. A cutout  15  is formed along the edge of the sheet  10  which does not have a border  14  so that a photograph may be grasped in order to remove it from the frame assembly. 
     In the exemplary embodiment, a first pair of spaced apart cut lines  16   a  and  16   b  are formed or die cut in sheet  10  and extend from a pair of spaced apart points  18   a,    18   b , respectively. The lines  16   a,    16   b  cut through the thickness of the sheet  10  and extend from the points  18   a,    18   b  through edges  20   a  and  20   b  of the sheet to define a first plastic strip  22  separated from the sheet by the lines, which strip becomes the stand for supporting the plastic sheet  10  in an upright position. A thinned linear area or groove  24  is formed between the pair of points  18   a ,  18   b  to create a plastic hinge such that the first strip  22  can be bent at an angle out of the plane of the plastic sheet  10 . It will be noted that the strip  22  is positioned such that a distal end is defined by the edges  20   a  and  20   b  so that a portion of the distal end is parallel to edge  20   a  and another portion is parallel is edge  20   b.  This design allows the strip  22  to function as a support for orienting the sheet in either a sideways or upright position. The strip  22  could also be formed such that it intersects only one edge of the sheet  10 , but that would limit the orientation of the photograph frame to one position when supported by the strip  22 . 
     A second plastic strip  26  is defined within the first plastic strip  22  by another pair of cut-through lines  28   a,    28   b  extending from a first end  30 . The strip  26  is preferably oriented to run concurrently with the first strip  22 . The end  30  is established by a thinned area or groove  32  extending between a pair of spaced apart points  34   a,    34   b  on the first plastic strip  22 . A second or distal end  36  of the second plastic strip  26  is defined by a cut-through line  38  extending partially across the first plastic strip. This arrangement allows the second plastic strip  26  to be bent out of the plane of the first plastic strip  22 . 
     It can be seen that the lines  16   a ,  16   b  are cut such that the first strip has a generally hour glass shape defined by a narrow section located at about ⅓ of the distance between the groove  24  and an outer end  40  of the strip. The groove  32  establishing the first end  30  of the second plastic strip  26  is located at the narrowest point between the lines  16   a,    16   b.  The second plastic strip  26  is shaped by the lines  28   a,    28   b  to be wider at the distal end  36  than the width of the first strip  22  at the groove  32  such that when the strip  26  is bent out of the plane of the first plastic strip  22 , edges of the end  36  will abut against the sheet  10  outside the first plastic strip  22 . As best seen in  FIG. 1 , there are two truncated grooves  42   a,    42   b  extending into the sheet  10  and aligned with the groove  32 . 
     Referring to  FIG. 2 , the first strip  22  is shown bent out of the plane of the sheet  10  to create a support stand for the backing plate or sheet. The strip  22  is maintained in the extended position by the second strip  26  being bent back out of the plane of the first strip  22  with the outer edges of the distal end  36  positioned in the grooves  42   a,    42   b  to thereby lock the strip  26  in position. As will be appreciated, the plastic memory inherent in the plastic material of the sheet  10  will cause the strip  22  to be biased toward its initial position in the plane of the sheet thereby pressing the strip  26  toward the sheet  10  so that it is maintained in contact with the grooves  42   a ,  42   b  and keeping the strip  22  in a supporting position for the photographic frame. It can also be seen that the frame can be supported by the strip  22  with either the edge  20   a  being at a bottom of the frame in a display position or with the edge  20   b  being at a bottom of the frame in another display position.
