Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention generally relates to clips for securing sheets of paper and, in particular, to clips that are adapted to grip sheets of paper while, preferably, being positioned about the corners of the sheets.




2. Description of the Related Art




Generally, it is known to secure loose sheets of paper by utilizing various fasteners, such as staples and paperclips, among others. In this regard, double clips have been utilized that incorporate a body, typically made from a band-like plate, and a pair of fingergrips attached to the body. The body of such a double clip includes a back portion configured to have a length substantially corresponding to a maximum clipping thickness of the clip, and abutment portions extending outwardly from the back portion. Respective free ends of the abutment portions extend inwardly toward each other and abut against each other elastically. The pair of fingergrips, which typically are formed from hard metal wire, are rotatably engaged by the free ends of the abutment portions. So configured, a stack of sheets of paper may be engaged and securely retained by the clip by rotating the free ends of the two fingergrips toward the back portion of the body, and then, once engaging the back portion, towards each other, thereby spreading the free ends of the abutment portions to form an opening for placing the papers therein. Once the papers are suitably positioned, the fingergrips may be released, thus allowing the free ends of the abutment portions to be elastically urged toward each other so that the papers are secured therebetween.




As is known, the aforementioned double clip is particularly well suited for gripping a stack of sheets of paper; however, the band-like plate of the abutment portions oftentimes tends to obstruct an appreciable portion of the uppermost and lowermost sheets of such a stack from view. Therefore, there is a need for improved clips which address these and other shortcomings of the prior art.




SUMMARY OF THE INVENTION




Briefly described, the present invention relates to a clip that is adapted to grip sheets of material, such as paper, while the clip is positioned about the corners of the sheets. In this regard, a preferred embodiment of such a clip includes a body formed from a length of band-like material. The body incorporates a back portion and first and second abutment portions extending outwardly from the body portion. Free ends of the abutment portions are formed at opposing ends of the body and are configured to engage each other. A pair of fingergrips also are provided that are configured with two legs that are spaced from each other. Each of the fingergrips include a gripping end and a pair free ends, with the free ends being retained at respective free ends of the abutment portions. Additionally, a corner-receiving opening is formed through the back portion, with the corner-receiving opening being characterized by a width greater than the spacing of the legs of the fingergrips. So configured, the corner-receiving opening may receive therethrough a corner portion of a stack of sheets of material.




An alternative embodiment of the clip includes a body, a pair of fingergrips, and means for receiving therethrough a corner portion of a stack of sheets of material.




Other features and advantages of the present invention will become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such features and advantages be included herein within the scope of the present invention, as defined in the appended claims.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT




Referring now to

FIGS. 1 and 2

, a representative prior art clip


11


will be described in greater detail. As depicted in

FIG. 1

, clip


11


incorporates a body


14


which is formed by bending a band-like metal plate, i.e., a plate formed of steel, stainless steel, or the like, and fingergrips


25


made from hard metal wires. Body


14


includes a back portion


12


and a pair of abutment portions


13


that are formed by bending the plate. The back portion


12


has a length substantially corresponding to the maximum clipping thickness of the clip


11


. The back portion


12


and the abutment portions elastically engage each other so that free ends of the abutment portions may abut against each other. At the free ends of each of the abutment portions


13


, a pair of lock portions


15


is formed, such as by bending the edges of the free ends into rings. Additionally, an edge portion


16


of the abutting edge between the locking portions


15


may be bent in a manner similar to the locking portions.




As shown in

FIGS. 1 and 2

, an opening


22


preferably is provided substantially in a widthwise center portion of back portion


12


. Notches


23


are formed in the respective abutment portions


13


substantially in their widthwise center portions so that the notches


23


engage the opening


22


. Fingergrips


25


are rotatably inserted into the locked portions


15


with each fingergrip including a fingergrip body


26


. A distance between leg portions


27


and


28


of each of the fingergrip bodies


26


is made larger than the width of the opening


22


formed in the back portion so that when the fingergrip bodies


26


are gripped by fingers and rotated toward the back portion


12


, the fingergrip bodies


26


abut against shoulder portions


29


of the clip body


14


. So configured, the bent portions


17


and


18


which, generally, are caused to engage the respective fingergrips, are made to be fulcrums of rotation of the fingergrips


25


. Thus, when the fingergrip bodies


26


are gripped by fingers and caused to rotate about the respective fulcrums


17


and


18


, the free ends of the abutment portions disengage from each other so that a stack of sheets of paper


30


may be placed therebetween. For instance, when the stack of sheets of paper are to be clipped at the corner thereof (as depicted in FIG.


2


), the corner


32


of the stack may be inserted into the clip


11


so that the corner projects out through the opening


22


. However, due to the limited size of the opening


22


, i.e., the size of the opening being limited by the spacing of the legs of the fingergrips, a substantial portion


34


(depicted in cross-hatching) of the uppermost, as well as the lowermost, sheets of the stack may be obstructed from view.




Reference will now be made to

FIGS. 3 and 4

, which depict a preferred embodiment of the invention. As shown in

FIG. 3

, a preferred embodiment of the clip


100


includes a body


102


, and first and second fingergrips


104


and


106


, respectively. Body


102


incorporates a back portion


108


and a pair of abutment portions,


110


and


112


, which extend outwardly from the back portion and toward each other and, so that the distal or free ends


114


and


116


of the abutment portions engage each other preferably, the body is formed from a sheet of band-like material that is bent to form the various portions so that elastic forces of the material tend to urge the free ends of the abutment portions toward engagement.




The free ends of the abutment portions preferably include retainer portions, e.g.,


120


,


122


,


124


and


126


, which are adapted to receive free ends, e.g., ends


128


and


130


, and


132


and


134


of the fingergrips. So provided, the free ends of the fingergrips may be received and rotatably retained by the retainer portions.




In operation, e.g., when a stack of sheets of paper


136


are to be gripped by the clip


100


, the fingergrips may be rotated toward the back portion until the fingergrips engage the body. Thereafter, the gripping ends


140


and


142


of the fingergrips may be urged toward each other, thereby causing the fingergrips to pivot about respective fulcrums


144


and


146


of the body so that further urging of the gripping ends toward each other causes the free ends of the abutment portions to be drawn away from each other. Once the free ends of the abutment portions have been withdrawn a suitable distance from each other, e.g., a distance which is suitable to accommodate a thickness of a stack of sheets of paper to be gripped by the clip, the stack may be inserted between the abutment portions. The gripping ends of the fingergrips may then be released, thereby allowing the free ends of the abutment portions to securely engage the stack.




Referring more closely to the embodiment depicted in

FIGS. 3 and 4

, it should be noted that such an embodiment includes one or more enhancements, as compared to the prior art, which may intend to improve the functionality of the clip. In particular, preferred embodiments of the clip


100


include a corner-receiving opening


150


formed through the back portion that is adapted for receiving the corner portion


152


of a stack of sheets of paper therethrough, such as depicted in FIG.


4


. Preferably, the corner-receiving opening is characterized by a width that is greater than the spacing of leg portions, e.g., leg portions


154


and


156


, of the fingergrips of the clip. It is to be appreciated that such a large opening, as compared to the size of the body of the clip, may allow for a more secure engagement of the abutment portions about a stack of sheets of paper and may enhance the ability of the clip to secure the sheets of such a stack.




Additionally, one or more of the abutment portions may include an opening


160


which may have a width that is greater than the spacing of the legs of the fingergrips. So provided, the opening(s)


160


may provide for an increased unobstructed viewing area of the uppermost and/or lowermost sheets of a gripped stack, thereby allowing a viewer to view a greater portion of the uppermost and/or lowermost sheets of the stack without having to reposition the clip during viewing. For those embodiments incorporating one or more openings


160


, as well as a corner-receiving opening, it is envisioned that an enlarged opening


160


tends to compensate for the potential of the clip to obstruct the view of a greater portion of the uppermost and/or lowermost sheets of the stack, as compared to the prior art, as the corner-receiving opening allows the clip to be positioned closer to the center of the sheet. The reduced obstructed area of view


164


is depicted in crosshatching.




Although depicted as forming a portion of the respective abutment portions, (not shown) the fulcrums or beams may be formed as portions of the back portion and/or the abutment portions, (as depicted in

FIGS. 3 and 5

, for example) as desired.




Referring now to

FIG. 6

, an alternative embodiment


100


′ will be described in greater detail. As shown in

FIG. 6

(which is depicted absent fingergrips), body


102


′ includes a back portion and respective abutment portions


110


′ and


112


′ that do not incorporate beams. In contrast to the beamed-configuration of the embodiment depicted in

FIGS. 3-5

, the embodiment


100


′ incorporates a beamless structure of the abutment portions is sufficiently robust to maintain structural integrity of the body. In particular, the free ends incorporate retainer portions


170


and


172


, respectively. The retainer portions preferably are adapted to receive free ends of a fingergrip in an inwardly disposed direction, in contrast to the outwardly disposed direction of the retainer configuration in the embodiment depicted in

FIGS. 3 and 4

(such a retainer configuration also is depicted in FIG.


5


). It should be noted that the lack of a beam increases the unobstructed viewing area.




As shown in greater detail in

FIGS. 7 and 8

, the embodiment


100


′ utilizes the substantially outermost opposing portions of the abutment portions as fulcrums for engaging the fingergrips, e.g., fingertip


104


′, (only one fingertip is shown for clarity and ease of description). So configured, the segregated corner-receiving opening


150


and opening(s)


160


of the embodiment


100


preferably are replaced by a contiguous opening


180


which functions both as a corner-receiving opening and an opening for providing an improved unobstructed view of the uppermost and lowermost sheets of a stack of paper to be received by the clip.
