Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to office supplies and more particularly pertains to an improved paper clip construction. 
     2. Description of the Prior Art 
     There is a plethora of different designs for paper clips. In its most ubiquitous form, a paper clip is a wire device formed of internesting elongate wire loops with a single loop facing in one direction and a pair of nesting loops facing in the other direction. A good example of such a well known paper clip style is shown in FIG. 1 of U.S. Pat. No. 4,237,587 which issued to Hsiao et al. on Dec. 9, 1980. In reviewing this standard form of paper clip, it will be noted that only one end of the clip can be utilized to clip pieces of paper together. As such, when a paper clip is removed by a worker for the purpose of clipping sheets of paper together, the worker must first determine the correct end of the clip and align it accordingly. This greatly increases the task of clipping sheets of paper together, both in time and effort, and accordingly, there exists a continuing need for new and improved paper clips which could be more easily aligned and utilized in performing this simple office function. In this respect, the present invention substantially fulfills this need. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of paper clips now present in the prior art, the present invention provides an improved paper clip construction wherein the same can be utilized from either end to clip sheets of paper together. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved paper clip construction which has all the advantages of the prior art paper clips and none of the disadvantages. 
     To attain this, the present invention essentially comprises an improved paper clip which is provided with an extra loop of wire so that the clip can be used from either end to attach papers together. Modifications include providing the clip with serrated gripping edges, bend points and adhesively attachable labels. 
     There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference now to the drawings, and in particular to FIGS. 3, 4 and 5 thereof, a first embodiment of a new and improved paper clip embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     Initially however, reference is made to FIGS. 1 and 2 of the drawings wherein prior art paper clips are illustrated. The paper clip shown in FIG. 1 is the ubiquitous form of the clip over which the present invention comprises a substantial improvement. As shown, this paper clip includes a first end 12 consisting of a single wire loop and a second end 14 having an internested loop 16. As is well known by those who utilize paper clips, only the end 14 of the clip shown in FIG. 1 can be utilized to clip papers together since both of the wire loops 14, 16 are required to grasp overlying sheets of paper. The end 12 cannot be utilized since a second loop is not available for positioning on opposed sides of a sheath of papers. Accordingly, before the paper clip shown in FIG. 1 can be utilized, it must be aligned so that the end 14 points toward the papers to be clipped together, and this often results in a very time consuming operation. 
     FIG. 2 of the drawings illustrates a prior art paper clip of the type shown in U.S. Pat. No. 4,286,358 which issued to Gary Levin on Sep. 1, 1981. This paper clip provides the dual function of being utilized to clip papers together and also serves as a labeling or advertising means. Both of the paper clips illustrated in FIGS. 1 and 2 represent the current state of the art over which the present invention comprises a substantial improvement. 
     As shown in FIGS. 3, 4 and 5, the paper clip 10 comprising the present invention includes the aforedisscussed wire loops 12, 14, 16, and further includes an extension of the loop 16 into a continuous further loop 18 that is internested within the loop 12. As such, this basic embodiment of the present invention provides for wire loops 12, 18 at one end and loops 14, 16 at the other end, whereby either end of the paper clip 10 can now be utilized to clip sheets of paper together. As such, a user of the paper clip 10 need not initially align the paper clip with the correct end pointing toward the sheath of papers inasmuch as either end can now be utilized. 
     FIG. 6 of the drawings illustrates a modified embodiment of the present invention which is generally designated by the reference numeral 20. In this embodiment 20, at least one wire loop 16 is provided with a serrated edge 22 comprising a plurality of gripping teeth. With the wire loop 16 overlying a sheath of papers and the loop 14 being positioned beneath the papers, the gripping teeth 22 prevent the paper clip 20 from becoming unintentionally disengaged therefrom. 
     FIGS. 7 and 8 illustrate a third embodiment of the present invention which is generally designated by the reference numeral 24. This embodiment is similar in all respects to the embodiment shown in FIG. 6 with the exception that the wire loop 18 is turned upwardly as best illustrated in FIG. 7 whereby the two loops 12, 18 no longer lie in the same horizontal plane. This configuration provides for a guided movement of the end 12 of the clip 24 to thus allow papers to be more easily aligned between the two loops 12, 18. Additionally, narrowed portions 26, 28 are disclosed on the wire loop 12, thus to facilitate a selective bending of this loop downwardly if desired. This increases the angle between the planes of the wire loops 12, 18 so as to provide an even larger paper receiving opening to assist in the utilization of this embodiment 24 of the invention. 
     FIGS. 9, 10 and 11 illustrate a fourth embodiment of the invention which is generally designated by the reference numeral 30. In this embodiment, the paper clip 24 is utilized in combination with a T-shaped label 32 positionable over the loop 14. As best illustrated in FIG. 11, a flexible, rupturable glue pouch 34 is positioned within the cavity 36 designed to receive the wire loop 14, and the forced positioning of this wire loop within the cavity results in a rupturing of the glue pouch so as to firmly affix the label 32 to the paper clip 24. This embodiment 30 of the invention allows a paper clip to provide the dual function of clipping sheets of paper together while also being utilized as a labeling means. As is apparent, the cavity 38 forming a part of the T-shaped label 32 is designed to receive a card having pertinent information imprinted thereon. The card is slidably positionable within the cavity 38 in a now well understood manner. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
