     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to peripheral devices for personal electronic equipment, and in particular to devices used with small portable electronics such as smartphones. 
     Description of the Related Art 
     Small electronic devices, such as smartphones, are becoming ubiquitous. It can be difficult to maintain these devices, i.e. to hold these devices, due to the shape of the device and the human hand. People frequently drop such devices, and in some instances, there can be an urgency in performing other tasks with one&#39;s hands while maintaining control over such devices. 
     Certain devices have been offered to address this issue, including but not limited to devices that effectively tether the electronic device to the user, such as to his or her finger or wrist, as well as simple rings attached to the device wherein the user can slip his or her finger or fingers through the ring so attached. However, none of these devices allow for the ability of the user to quickly and efficiently “flip” the phone such that the user can use his or her hands, or “flip” the phone back into his or her palm with minimal effort. Existing devices, such as the aforementioned tethers and rings, are either impossible to employ to repel and retract or take significant effort and are cumbersome or awkward as a result. No device currently known allows for a quick and relatively minor flick of the wrist to move away from and return to the palm of a user&#39;s hand. 
     Thus, there remains a need to provide a device that overcomes the drawbacks identified above. 
     SUMMARY OF THE INVENTION 
     According to the present design, there is provided an apparatus comprising a base and a loop attached to the base. The loop is joined to the base at a first position at a first length from a first end and further joined to the base at a second position at a second length from the first end. The loop includes an unbound section and the loop is further joined to the base at a third position proximate the first end. The base comprises an adhesive on a side opposite the loop. 
     According to a further embodiment of the present design, there is provided a method for constructing an apparatus to maintain an electronic device, comprising providing a base and a loop, attaching the loop to the base at a first position at a first length from a first end, further attaching the loop to the base at a second position at a second length from the first end, further attaching the loop to the base at a third position proximate to the first end, thereby producing an unbound section of the loop, and joining the base to the electronic device such that an axis of rotation formed by the loop is vertically offset from a centerline of the electronic device. 
     Various aspects and features of the disclosure are described in further detail below.

     DETAILED DESCRIPTION 
     The following detailed description is of the best presently contemplated modes of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims. In certain instances, detailed descriptions of well-known devices and mechanisms are omitted so as to not obscure the description of the present invention with unnecessary detail. 
       FIG. 1  illustrates a first aspect of the present design showing a perspective view of one embodiment of the design. According to  FIG. 1  there is provided a back or backing  101  that can take various forms, including circle, oval, square rectangle, diamond, or an irregular shape, but virtually any shape may be employed. The other side of the backing, not shown in  FIG. 1 , may include an adhesive that allows joining to the device  102  in a secure manner Virtually any means for joining may be employed, including the aforementioned adhesive as well as a mechanical joining arrangement, such as clips or other connectors that premix affixation to the device  102 , tape, glue, or even connections to an intermediate device such as a device cover, including but not limited to pins, screws, and the like, or any other devices, apparatus, systems or arrangements known in the field. In one instance, a cover may be made of a deformable material, placed with the device  102 , such as engaging the device as a cover, and the backing  101  may be simply screwed into the deformable material. The joining adhesive or apparatus or other arrangement typically and preferably securely connects the backing  101  to the device  102 . 
     The apparatus also includes strap  103 . Strap  103  has been sized to enable a typical user to easily “flip” the phone using a single finger and its dimensions have been thoroughly investigated. A typical current smartphone ranges in size from about 115.2 mm by 58.6 mm (Apple iPhone 4/4S) to about 162.9 mm by 80.7 mm (Samsung C9 Pro) with certain phones having one or the other dimension greater than the Samsung or less than the Apple. Weights for Apple devices, which are somewhat representative of all smartphone devices offered, range from approximately 113 g to 202 g. Some devices are larger or smaller than these weights. Even though these devices tend to range in size and weight, they are not as large as what have been called “tablet” devices, and the current design is primarily directed to attachment to smartphone sized, and in some cases smaller, designs. Smaller designs may include portable music devices such as iPods or similar designs. 
       FIG. 2  is a front view of one embodiment of the present design, while  FIG. 3  is a rear view showing the backing, which may include an adhesive or other material intended to join the device to the phone or electronic device.  FIG. 4  is a right side elevation view of one embodiment of the device,  FIG. 5  a left side elevation view,  FIG. 6  a top view, and  FIG. 7  a bottom view of this embodiment of the design. 
       FIG. 8  is a rear view of the design attached to phone device  802 , including base  801  and strap  803 . In a typical arrangement, the device is attached as closely as possible to the center of the rear of the device.  FIG. 9  shows phone  802 , representing any appropriately sized electronic device, with backing  810  and loop  803  shown. Also shown, and pertinent to this design for the ability to “flip” the device, is the direction of motion  901 , axis of rotation  902 , the phone centerline  903 , and the offset separation  904  desirable to facilitate rotational acceleration. It is intended that the center of backing or base  801  be positioned slightly offset vertically from the centerline of the smartphone or electronic device as shown, such as with separation  904 . 
     In operation, the electronic device, e.g. smartphone, may be held with the forefinger through the loop with at least one other finger, such as the pinky and/or middle finger, used for setting the user&#39;s angle of comfort for viewing. The intent is for a user to maintain use of the hand for gripping objects while the cell phone is retained hanging from the forefinger. One aspect of the design is its novel use of the center of gravity of the cell phone and changes in location of a fulcrum. 
     Reference is directed to the slidable movement of the forefinger from one side of the center of gravity to the other side. This results in an improved stability and a more secure feel when the cell phone is flipped from viewing mode to its mode where objects can be gripped or held. A single strap, or loop, or loop strap, without the ability to change its fulcrum may at times require the use of the other hand to assist in rotation. Comparative testing has shown that the design is stable when used with only one hand. 
       FIG. 10  shows the specific dimensions of the loop.  FIG. 10  includes a view of the device  1000  including loop  1001  and base  1002 . In order to provide the rotational functionality discussed herein, including the desired axis of rotation when employed with a small electronic device such as a smartphone, the present design includes a loop  1001  having particular dimensioning. Loop  1001  may be constructed of any appropriate material, and in one instance non-phthalate PVC may be employed. 
     Sew line  1053  is a line approximately ⅜ of an inch wide, and in one embodiment exactly ⅜ of an inch wide, but generally plus or minus 20 percent of that figure. Loop distal end  1004  may be any length between the curved end shown in  FIG. 10  and the sew line  1053 . In one instance loop distal end may be approximately ½ inch in length between end and third sew line  1053 , plus or minus 20 percent. In one instance, the space between the curved end of loop distal end  1004  may be ¼ inch from the edge of backing or base  1002 . Finger loop  1001  runs unimpeded and unbound between third sew line  1053  to second sew line  1052  and is generally ⅝ inch wide, 2 mm thick, and finger loop  1001  may be, in its entirety, approximately 4 inches long. Finger loop  1001  may have exactly these dimensions or within plus or minus 20 percent of these numbers or some other value as discussed herein. Thus the length of finger loop  1001 , from tip to tip as shown in  FIG. 11 , may be anywhere from 3.2 inches to 4.8 inches in length, and may range less, such as 4.5 or 3.5 inches in length, or may be any other value, such as 4.1, 4.2, 3.9, or 3.8, depending on the person using the device and/or the size of phone used. In short, an approximately 4 inch length is used to provide the functionality discussed herein. 
     Second sew line  1052  is approximately ⅜ inch wide, and in one embodiment is not stitched to the edge to avoid tearing of the material. Again, this may be plus or minus 20 percent in sizing. Third sew line  1053  is also provided, again having the same general widths and dimensions as first sew line  1051  and second sew line  1052 . 
       FIG. 11  shows the basic dimensions employed, with a base  1101  approximately 2 inches wide and 3 inches high, plus or minus 20 percent or that amount exactly or close to that amount. Loop  1102  is 4 inches long and ⅝ inches wide in this view, and may be slightly larger or smaller or within 20 percent. In such a construction, the sew lines are positioned as shown in  FIG. 12 , where in the case of a 3 inch by 2 inch base, the third sew line  1203  is ¾ inch from the bottom  1206  of base  1204  in this view, first sewing line  1201  is ¼ inch from third sewing line  1202 , and second sewing line  1202  is ½ inch from first sewing line  1201 . Hence second sewing line  1202  is 1½ inches from the bottom  1206  of base  1204  in this embodiment, where as shown in  FIG. 10 , first sew line  1051  and second sew line  1052  bind one end of loop  1001 , the loop  1001  is folded or provided as shown in  FIG. 10 , and third sew line  1053  sews the distal end of loop  1001  to the base  1002 . Thus to construct the device of this embodiment, the squared off or beveled end of loop  1001  is placed on the base  1003 , first and second sew lines  1051  and  1052  applied, the loop formed and third sew line  1053  applied to create the loop and finish the design. 
     Relative positions of the loop are noteworthy. For an approximately four inch loop, and a 3 inch high base, the squared end of the loop may be placed on the base and the first sew line  1201  applied, followed by the second sew line  1202  ½ inch from the first sew line  1201  so applied, the loop formed and the third sew line  1203  applied to the distal rounded end as shown in  FIG. 10 . Thus for an approximately four inch loop of material applied to base  1204 , the near end of loop  1001  is placed on the position where third sew line  1203  will go, first sew line  1201  applied, 1 inch from the bottom  1206  of base  1204 , followed by application of second sew line  1202  ½ inch from first sew line  1201  and 1½ inch from the bottom  1206  of base  1204 . The loop  1001  is folded over and formed, and third sew line  1203  applied ¾ inch from the bottom  1206  of base  1204  and ¼ inch from first sew line  1201 . This forms the device shown in  FIG. 10 . Surface  1205  of base  1204  may include a graphic, such as a direct four color print onto the material, which may be 2 mm thick non-phthalate PVC or other material having different dimensions but providing the same or similar functionality. 
     The base, such as base  1204 , may therefore be formed of any appropriate material and may include 2 mm thick non-phthalate PVC in one embodiment, and the back side of the base  1204  may include an adhesive such as 3M 9465 PC double sided adhesive, manufactured and sold by 3M Corporation. In one embodiment, the squared end of loop  1001  may be beveled at an angle to “tuck” below the distal rounded end of loop  1001 , with the beveling shown in  FIG. 10 . In other embodiments, the end may be squared off or otherwise provided, and third sew line  1203  may be applied proximate to this beveled, squared or otherwise provided end. 
     Hence for a four inch length of loop material, a first sew line at the ¼ inch point of the loop material may be provided and a second sew line at the ¾ inch point, ½ inch from the first sew line, followed by loop material for 2¾ inch, unimpeded and unbound, before the sewing of third sew line ¼ inch behind first sew line forms the device. So of a four inch piece of material, 2¾ inch, or approximately 68.75 percent of the material, forms the loop between the second sew line and third sew line, enabling the efficient “flipping” of the current design. Other dimensions may be employed, but differences of 1%, 2%, 5%, 10%, or 20% of any dimension mentioned may be employed in any combination. For example, one dimension may be identical or similar to the dimension recited herein, while another dimension may vary 1%, 2%, 5%, 10% or 20% from the dimension provided herein. 
     To be clear, as used herein, the term “approximately” means one of a difference of 1%, 2%, 5%, 10% or 20% from the measurement provided. Use of the term “proximate to” means near or close to, and in some cases at the same point or line. Thus the phrase “attached [or joined] at a line proximate to an end” in this context means the element is provided on or at the line or near the line, where near means approximately at the line, i.e. one of a difference of 1%, 2%, 5%, 10% or 20% from the identified item. Further, as used herein, terms such as “phone” “device” smartphone” “electronic device” and the like are employed, and such terms are not intended to be limiting but to represent any of the class of products to which the current design may be attached. 
       FIGS. 13A through 13H  show a number of different base designs.  FIGS. 13A and 13B  show a first base design in perspective and front view, respectively, and is called the “oval” design.  FIGS. 13C and 13D  show a first alternate base design in perspective and front view, respectively, and is called the “ticket” design.  FIGS. 13E and 13F  show a second alternate base design in perspective and front view, respectively, and is called the “tag” design.  FIGS. 13G and 13H  show a third alternate base design in perspective and front view, respectively, and is called the “rectangle” design. As noted, virtually any reasonable shape base may be employed including ones not pictured here. One particular consideration is the offset separation between the device or smartphone centerline and the loop axis of rotation reflected in  FIG. 9 , but using that relationship, essentially any base shape that can accommodate a similar loop is acceptable for use in the current design. 
     While attachment is primarily described herein with respect to sew lines and sewing, it is to be understood that attachment can be provided in any appropriate manner, including but not limited to use of adhesives, rivets, clips, staples, and/or any other reasonable means for joining. In all instances, three points of adjoining are preferably provided, but more points may be employed, and if some form of adhesive is applied or some other means that cover a larger space, fewer than three may be employed. 
     It is noted that the resiliency of the loop formed in the device allows the fulcrum, here the index finger, to change its pivotal location thereby also moving its point of axis relative to the center of gravity of the device.  FIG. 14  shows the resilient loop extended by the centrifugal force of the device that allows the finger more room to change its center of rotation. Dynamic stretching in this construction and in this manner allows the pivot to move relative to the center of gravity of the device. This change in center of rotation is an improvement over other products currently available. 
     From the Figures presented, it is to be understood that the product is placed at the vertical center of the smartphone&#39;s surface, but the finger loop is slightly offset from the centerline, allowing for additional rotational acceleration when the device Because of the shape and attachment orientation of the finger loop, a rounded surface is always in contact with the finger. Such a geometry acts like a collar (the finger loop) on an axle (the finger, facilitating the free rotation of the phone when being flipped. Again, the shape of the loop allows the finger to always be in contact with the rounded surface, allowing for easy rotation of the phone. 
     When sewing is employed, one stitch on the product is positioned directly under the centerline of the phone, which is also directly under the user&#39;s finger. This stitch helps create the shape of the loop and keeps the loop attached to the device at the point of rotation, which limits the movement of the loop and facilitates rotation when flipped. Two offset stitches on the loop holds the loop in place, limiting motion of the loop, facilitating rotation of the phone when flipped. The offset distance between the two stitches maintains the necessary shape of the loop to facilitate the “flipping” action. In the sew line instance, stitching placement limits the movement of the flexible vinyl material. While a certain amount of movement or flexibility is beneficial, too much movement negatively impacts “flipping” operation. Movement of various centers of rotation is shown in  FIG. 15 . 
     Thus according to the present design, there is provided an apparatus comprising a base and a loop attached to the base. The loop is joined to the base at a first position at a first length from a first end and further joined to the base at a second position at a second length from the first end. The loop includes an unbound section and the loop is further joined to the base at a third position proximate the first end. The base comprises an adhesive on a side opposite the loop. 
     According to a further embodiment of the present design, there is provided a method for constructing an apparatus to maintain an electronic device, comprising providing a base and a loop, attaching the loop to the base at a first position at a first length from a first end, further attaching the loop to the base at a second position at a second length from the first end, further attaching the loop to the base at a third position proximate to the first end, thereby producing an unbound section of the loop, and joining the base to the electronic device such that an axis of rotation formed by the loop is vertically offset from a centerline of the electronic device. 
     The above description is for the best presently contemplated modes of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims. In certain instances, detailed descriptions of well-known devices, mechanisms and methods are omitted so as to not obscure the description of the present invention with unnecessary detail.
