Description:
FIELD OF THE INVENTION 
       [0001]    This invention generally relates to devices and processes for folding sheet like articles such as bottom sheets (fitted), top sheets, blankets, table cloths, drop cloths, tarps, and the like. The invention is especially suited for folding fitted or contoured sheets (e.g. fitted bottom bed sheets that incorporate an elastic type material). The invention is appropriate for low volume folding type of environments. 
       BACKGROUND OF THE INVENTION 
       [0002]    The present invention is directed to situations where occasional low volume folding is required. Environments with such low folding demands include the home, bed and breakfast establishments, small shops, and the like. In contrast, it is common in high volume folding environments (e.g. textile manufacturing &amp; packaging plants, large hotel laundry departments) to find large, complex, expensive, semiautomatic to fully automated folding machines designed to keep up with the substantially large folding demands. Such high volume folding equipment, though efficient, is not appropriate for the low volume folding environment where article folding is an occasional occurrence. The folding apparatus needs for the occasional use, low volume folding environment is directed to units that are inexpensive, safe, compact, etc., whereas, the high volume folding environments are mainly focused on production or throughput. 
         [0003]    Many have experienced the frustration of folding sheets like articles such as bottom sheets (fitted) top sheets, blankets, table cloths, drop cloths, tarps and the like. For many, this is a clumsy task, especially when it comes to fitted sheets, that is, contoured sheets with elasticized bands located on their entire, or a portion, of the sheet&#39;s periphery. These bands snugly engage the bottom and/or side of a mattress to prevent slippage and the sheet from dislodging during use. Folding bed sheets is a housekeeping chore that is performed to aid in sheet storage and prevent wrinkled bed coverings. In the commercial or institutional setting, the folding of bed sheets and the like is a housekeeping chore that some workers must regularly and repeatedly endure. 
         [0004]    Elderly, frail, invalid or disabled individuals often find it difficult, or even impossible, to lift and stretch articles such as bed sheets in a manner that facilitates easy folding. Some find it difficult to bend at the waist or difficult to use the fingers with precision to fold and manipulate the bed sheet at the corners. Children are well-known to have difficulty folding bed sheets in manner that results in a neat appearance. This can be especially challenging where, as is often the case in children, where the bedding is substantially longer that the child. 
         [0005]    A folded sheet product that deviates from the well established rectangular shape tends to yield a disorganized untidy appearance. Similarly, a series of folded products having non-uniform final dimensions is yet another situation that can create an untidy appearance, especially if several folded articles are vertically stacked. Furthermore, stacking folded articles having non-uniform final dimensions often leads to stack instability as well as storage problems. Stack instability can be of particular concern where the folded articles run the risk of being bumped (e.g. retail situations, hotel housekeeping cart, and the like). 
         [0006]    Description/discussion of the related art; U.S. Pat. No. 6,814,269 to Fernandez, and U.S. Pat. No. 6,360,927 to Barker describe devices that function in the horizontal position (e.g. tabletop or the like) and are geared toward the folding of upper body garments (e.g. shirts and tops). U.S. Pat. No. 6,685,065 to Ebling et al. discloses a similar folding aid including a telescopically adjustable center member. While, in contrast, U.S. Pat. No. 5,816,434 to Weinstein discloses a folding device having a spring clip and holding bar, where the device is mounted to a vertical surface such as a wall. Both U.S. Pat. No. 6,269,987 to LaPace et al., and U.S. Pat. No. 6,015,069 to Christensen disclose folding devices that are in the form of a table or table like structure. Such designs and the like, do not provide a user with a compact inexpensive folding device for low volume folding situations; furthermore the known difficulties in folding fitted sheets are not addressed. The previous discussion along with the aforementioned references reveals many shortcomings associated with sheet folding aids for low volume folding situations. 
         [0007]    The purpose of the present invention is to overcome several of the shortcomings affiliated with the prior art as well as the introduction of additional novel features.

         [0041]    Also, in this disclosure, the term “exemplary” shall possess only one meaning; wherein the sole definition pertains to serving as an example, instance, or illustration. 
       DETAILED DESCRIPTION 
       [0042]    In the following is described several embodiments of the Sheet Folding Device of the present invention. In describing the embodiments illustrated in the drawings, specific terminology will be used for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents that operate in a similar manner to accomplish a similar purpose. 
         [0043]    In this context, the Sheet Folding Device may be constructed of any relatively rigid material such as various plastics, polymers, metals, woods, metals, metal alloys, rubbers, synthetic rubbers, rubber-like materials, composite materials, or the like. In preferred embodiments the device would be constructed from moisture resistant, wear-resistant, light weight, rigid, thin materials such as aluminum, ALUMACORR, SINTRA/PVC, Foamboard, GATORFOAM, CORTEX, SIGNBOND, Styrene, PVC foam board, to name a few. For purposes of this application, however, the Sheet Folding Device will be referred to as if constructed from PVC foam board. The PVC foam board is polymer based material that is but one of many preferred material choices that possess many of the aforementioned desired material properties. A specific example of such a PVC foam board material is the Excel PVC Free Foam product, available from the Jain Inc. of Columbus, Ohio. Additionally, by way of example, but not limitation, said Sheet Folding Device may be formed of a moldable high strength, resilient impact resistant plastic material. Optionally the Sheet Folding Device materials aforementioned can be perforated to reduce weight, increase ventilation, and the like. 
         [0044]    There are several joint or hinge types that will adequately function in the Sheet Folding Device application, one such example is piano hinge, or continuous hinge in conjunction with appropriate fastening means such as nuts &amp; bolts, screws, rivets, adhesives and the like. Preferred hinge materials include various plastics, polymers, metals, metal alloys, rubbers, synthetic rubbers, rubber-like materials, composite materials or any other materials that possess preferred properties which include moisture resistance, wear-resistance, light weight, rigidity. A preferred hinge design is one that incorporates both the fastening function and the hinge function, thereby streamlining the device design and fabrication thereof. One such example of a preferred combination hinge successfully tested is Plastic Panel Hinge P/N 108-640, available from Outwater Plastics industries Inc. of Bogota, N.J. 
         [0045]    Other suitable hinges include butt hinges, slip hinges, flag hinges, liftoff hinges, as well as other hinge types generally known in the industry. Additional methods of providing a reliable hinging means to join the PVC panels, or equivalently create connected panel like segments include the use of polymeric living hinges. Living hinges are generally created by the placement of a thin portion of material bridging two heavier portions of the same material. They provide the ability to flex repeatedly without the use of a classical mechanical hinge. Again, using such a technology, one can construct a device from one continuous piece of polymeric material followed by subsequent hinge creation processes (a well known process in the polymeric industry) potentially leading to a durable inexpensive product. 
         [0046]    In another embodiment, the Sheet Folding Device comprises two or more sections cooperatively assembled to the desired configuration. For example, the panels and joints or hinges may be separately manufactured and joined together by known manufacturing methods such as mechanical fasteners, heat welding or by the use of adhesives. These sections can be either temporarily or permanently affixed to each by means known to one skilled in the art. 
         [0047]    Many types of sheet type products can be folded using this device. However, this application will generally refer to fitted or contoured sheets which are known to be one of the most challenging types of sheet product to fold uniformly. Yet, it is to be understood that this device can be used to fold flat sheets, duvets, tablecloths, blankets, comforters, oversized towels, bedspreads, drop cloths, tarps, among other relatively large sheet type products. An advantage of using the folding device is that all processed completely folded sheet products folded by the device will all achieve substantially similar final folded dimensions. The relatively uniform condition of the finished (completely folded) sheet products enables enhanced stacking properties, predictable storage strategies (e.g. placement into storage bags, closets, drawers), a neat organized appearance, and the like. 
         [0048]      FIGS. 1A and 1B  illustrates an overall perspective front-top view and a front view respectively, of the manually operated sheet folding device  100  with hinges  116  in the unfolded condition having a front face  102  and a back face  104 . 
         [0049]      FIG. 2  illustrates a front view of the sheet folding device depicting a first folding panel pair  210  having first panel  110 A and a second panel  110 B, a second folding panel pair  212  having a first panel  112 A and a second panel  112 B, and a third folding panel pair having a first panel  114 A and a second panel  114 B. 
         [0050]    The first panel  110 A of first folding panel pair  210  comprises a top edge  210 A 1  having a first cut-out  110 A 1  and a second cut-out  110 A 2 , a bottom edge  210 A 2 , a left edge  210 A 3 , and a right edge  210 A 4 . The second panel  110 B of first folding panel pair  210  is substantially a mirror image of first panel  110 A, and comprises a top edge  210 B 1  having a first cut-out  110 B 1  and a second cut-out  110 B 2 , a bottom edge  210 B 2 , a left edge  210 B 3 , and a right edge  210 B 4 . 
         [0051]    The first panel  112 A of second folding panel pair  212  comprises a top edge  212 A 1  having a first cut-out  112 A 1 , a bottom edge  212 A 2 , a left edge  212 A 3 , and a right edge  212 A 4 . The second panel  112 B of second folding panel pair  212  is substantially a mirror image of first panel  112 A, and comprises a top edge  212 B 1  having a first cut-out  112 B 1 , a bottom edge  212 B 2 , a left edge  212 B 3 , and a right edge  212 B 4 . 
         [0052]    The first panel  114 A of third folding panel pair  214  comprises a top edge  214 A 1  having a first cut-out  114 A 1 , a bottom edge  214 A 2 , a left edge  214 A 3 , and a right edge  214 A 4 . The second panel  114 B of second folding panel pair  214  is substantially a mirror image of first panel  114 A, and comprises a top edge  214 B 1  having a first cut-out  114 B 1 , a bottom edge  214 B 2 , a left edge  214 B 3 , and a right edge  214 B 4 . 
         [0053]    Referring to  FIGS. 1A ,  1 B and  2 , the connections among first, second, and third panel pairs  210 ,  212 , and  214  respectively are as follows, right edge  214 A 4  of first panel  114 A of third folding panel pair ( 3 FP)  214  is hingedly connected to left edge  212 A 3  of first panel  112 A of second folding panel pair ( 2 FP)  212 . The right edge  212 A 4  of first panel  112 A of  2 FP  212  is hingedly connected to left edge  210 A 3  of first panel  110 A of first folding panel pair ( 1 FP)  210 . The right edge  210 A 4  of first panel  110 A of ( 1 FP)  210  is hingedly connected to the left edge  210 B 3  of second panel  110 B of ( 1 FP)  210 . The right edge  210 B 4  of second panel  110 B 4  of first folding panel pair ( 1 FP)  210  is hingedly connected to the left edge  212 B 3  of second panel  112 B of ( 2 FP)  212 . The left edge  212 B 4  of second panel  112 B of ( 2 FP)  212  is hingedly connected to the left edge  214 B 3  of second panel  114 B of ( 3 FP)  214 . 
         [0054]    As will be apparent, the size of the overall sheet folding device and its components can vary in size, as long as the basic intra-panel relationships are maintained, therefore the device can be adapted to most any series of standard sizes associated with a particular sheet type product as well as non-standardized products. 
         [0055]    The basic intra-panel relationships among the individual panels are exemplified in  FIG. 1B  and  FIG. 2 . Shown is the folding panel pairs increase in size starting with the outermost panels located on the extreme left and right, and progressing to the center panel pair. Such a size coordinated panel progression or layout, configures a nested array that enables the folding and inline nesting of the folding multiple panel pairs atop of one another. 
         [0056]    For example the sizing scheme of certain product may be delineated by the nomenclature or terms: small, medium and large, or compact, standard, and full, and so forth. In the area of bedding, the sizing scheme of sheet based products is dictated by a unique set of terms. The jargon used in this industry includes the basic terms: twin, full, queen, king, where each term is associated with a narrow set of rectangular dimensions for a given fitted sheet, flat sheet, comforter, duvet/quilt, etc. The rectangular dimensions associated with each of the terms can vary significantly depending on the type of bed (e.g. standard box spring based, waterbed, etc.), as well as the country of original design (e.g. U.S.A., U.K., E.U., etc.). This disclosure will primarily focus on the bedding standard of the U.S.A. for standard box spring/mattress type systems, with the understanding that achieving functionality with other sizing systems can be had by simple corresponding dimensional alterations of the sheet folding device. The basic dimensions for flat and fitted sheet products for bedding applications in the U.S.A. are presented in Table 1.

         [0057]    Referring to  FIG. 1B , in one embodiment of the present invention the following dimensions are within the working range associated with fitted and flat sheets (U.S.A. measurement system) with approximate standardized dimensions presented in Table. 1. The width associated with both first panel  110 A and second panel  110 B both have the same width  128  dimension, which is about 18 inches as presented in Table 2. Hinge width  132  is approximated at about ½ an inch, and represents the separation between all adjacent, hingedly connected panels here and throughout the disclosure. Width of first folding panel pair ( 1 FP)  118  is approximately 36 and ½ inches in width (see Table 3) and is designed to substantially approximate the width of “small” sheet products (e.g. Twin, as presented in Table. 1).  FIG. 5  depicts sheet folding device  500  configured for small sheet product  502 , mounted thereon. 
         [0058]    Height of sheet folding device  124  represents the height of all panels (i.e.  110 A,  110 B,  112 A.  112 B,  114 A,  114 B) and hinges  116 , whose dimension is approximately 39 inches in height and is designed to be longer than ½ of the sheet product&#39;s length, such that the once folded lengthwise sheet product is supported by the sheet folding device without engaging the floor (when the device is used in the upright position). Even though hinges  116  are shown having length  124 , other embodiments of the present invention can functionally utilize one or more hinges lengths shorter that length  124 . The width associated with both first panel  112 A and second panel  112 B both have the same width  130  dimension, which is about 9 inches. Likewise, the width associated with both first panel  114 A and second panel  114 B both have the same width  126  dimensions, which is about 7 and ½ inches. The thickness dimension of all panels in this and all embodiments in this disclosure is about ⅛ inches; the ⅛ inch thickness is a commonly manufactured panel dimension. Other thicknesses can be used, depending on the panel material properties such as stiffness, weight, expense, and the like. 
         [0059]    Referring to  FIG. 1B , Table 2, and Table 3, the summation of width dimensions associated with panels  110 A, 112 A,  110 B and  112 B, with corresponding hinge widths  132  yields the overall width of second folding panel pair ( 2 FP)  120 . The overall width of second folding panel pair ( 2 FP)  120  is approximately 55 and ½ inches and is designed to substantially approximate the width of “medium” sheet products (e.g. Full, Queen as presented in Table. 1).  FIG. 4  depicts sheet folding device  400  configured for small sheet product  402 , mounted thereon. Likewise, the summation of width dimensions associated with panels  110 A, 112 A,  110 B,  112 B,  114 A, and  114 B with corresponding hinge widths  132  yields the overall width of third folding panel pair ( 3 FP)  122 . The overall width of third folding panel pair ( 3 FP)  122  is approximately 71 and ½ inches and is designed to substantially approximate the width of “large” sheet products (e.g. Eastern King, California King as presented in Table. 1).  FIG. 3A  depicts sheet folding device  300  configured for large sheet product  302 , mounted thereon. 
         [0060]      FIG. 6  depicts an example panel hinge  600  having a left panel clamp  606  attached to left panel  602 , and a right panel clamp  608  attached to right panel  604 . Each panel clamp possesses a plurality of holding ribs  616  that functions as a holding means securing the panels to the panel clamps. The left panel clamp  606 —left panel  602  assembly moves in folding direction  612 , and the right panel clamp  608 —right panel  604  assembly moves in folding direction  614 , both movements based about the same pivot point or panel hinge center  610 . 
         [0061]      FIG. 3D  depicts a large sheet product  302  mounted on sheet folding device  300  in the completely folded, closed, or home position. In the completely folded, closed, or home position, all cut-outs  110 A 1 ,  110 A 2 ,  110 B 1 ,  110 B 2 ,  112 A 1 ,  112 B 1 ,  114 A 1 , and  114 B 1  located on panels  110 A,  110 B,  120 A,  120 B,  114 A, and  114 B align into one of either first access channel  312 , or second access channel  314 . The access channels  312  and  314  provide a means of grabbing and lifting a large sheet product  302  off of sheet folding device  300 . 
       Additional Features (Not Shown) 
       [0062]    Optionally, the cut-out features can be provided on both top and bottom edges of sheet folding device  300 , substantially duplicating the means of grabbing and lifting a large sheet product  302  on both ends of sheet folding device  300  enabling the device to be used in either orientation. Additionally, one or more apertures can be located on each of panels  110 A,  110 B,  120 A,  120 B,  114 A, and  114 B such that the plurality of aligning apertures creates a convenience feature. Such a convenience feature can function as a handle to assist the user in transporting the device, as a storage feature enabling the device to be stored on a hook, dowel, etc.; and the like. 
       Process or Method of Use 
       [0063]      FIGS. 3A ,  3 B,  3 C, and  3 D depicts an example process showing how a large sheet product  302  is mounted onto the sheet folding aid device  300 , folded, and removed. 
         [0064]    To use sheet folding aid device  300 , a user would select and arrange the appropriate panels to accommodate the size sheet product to be folded. For small sheet products, panels  112 A,  112 B,  114 A, and  114 B, are folded back in the stored position as depicted in  FIG. 5 ; optionally, panels can be added/removed to achieve the proper configuration. For medium sheet products, panels  114 A, and  114 B, are folded back in the stored position as depicted in  FIG. 4 ; optionally, panels can be added/removed to achieve the proper configuration. For large sheet products, panels all of the panels  110 A,  110 B,  112 A,  112 B,  114 A, and  114 B are used as depicted in  FIG. 3A ; again, panels can be optionally added/removed to achieve the proper configuration. Once the panel configuration is complete, the user positions the sheet folding device in the open, or semi-open state on level ground in the upright position such that cut-outs are situated on top as depicted in  FIG. 3A . 
         [0065]    The user would then proceed to the mounting step which involves the preparation of the sheet product followed by the placement onto the sheet folding device. Proper preparation of the sheet product is dependent on the type of sheet product that is to be folded. There are two basic types of sheet products, the fitted sheet product that possesses a box like generally rectangular geometry in its functional state, and the flat sheet that is a generally rectangular, planar, textile based article. In the case of a fitted sheet product, preparation would comprise folding the sheet product about its elongated dimension such that the width is unchanged while the elongated dimension is substantially halved. In addition, the user would ensure the alignment and nesting of the bottom two fitted corners of the fitted sheet product into the top two fitted corners thereof enabling placement of first nested fitted corner assembly  306  and second nested fitted corner assembly  308  onto sheet folding device  300  as depicted in  FIG. 3A . The preparation of a flat sheet product would comprise draping the elongated side of the flat sheet product over the sheet folding device  300  such that it is substantially centered about front face of sheet folding device  102  and back face of sheet folding device  104 . The flat sheet product can be optionally folded about its width dimension to correspond with the folded panel pair of choice prior to placement onto the prearranged panel configuration of the sheet folding device. A properly mounted sheet product should not engage the ground. 
         [0066]    Continuing with the folding of a large sheet product  308  depicted in  FIG. 3A , once the sheet product is mounted onto the sheet folding device, the user can commence with the folding process. The folding process, in the folding of a large sheet product example, starts with the folding of both the first panel of ( 2 FP)  112 A and first panel of ( 3 FP)  114 A moving in unison toward first panel of ( 1 FP)  110 A, and the folding of second panel of ( 2 FP)  112 B and second panel of ( 3 FP)  114 B moving in unison toward second panel of ( 1 FP)  110 B, ultimately arriving at the configuration depicted in  FIG. 3B . 
         [0067]    The next step in the folding process is the folding of the configuration depicted in  FIG. 3B  to the home position depicted in  FIG. 3C ; this is accomplished by folding the  110 A,  112 A,  114 A nested assembly toward the  110 B,  112 B,  114 B nested assembly. 
         [0068]    The user then grabs onto the stacked vertical layers of the large sheet product  302  using a pinching action via first access channel  312  and second access channel  314  and lifting in the first access channel sheet removal direction  316  and second access channel sheet removal direction  318 , respectively; best depicted in  FIG. 3D . 
         [0069]    Next in the sequence is the user folding the portion of the large sheet lifted off of folding device in a downward direction away from the user such that a series of horizontal folds are created atop of remaining sheet portion remaining on folding device. Optionally the folding device can be tilted backward toward the user to facilitate this step. The user repeats the lifting and folding steps until the large sheet product is completely removed from the folding device and in a uniform folded condition.
