Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention relates to molded plastic articles such as clothespins for suspending laundry from such as a clothesline, or multipurpose clamps such as bag clips, hobby clamps or ice tongs.




2. Description of Related Art




Wooden clothespins of the unitary simple split type and of the double jaw, spring-loaded type are well known.




However, the wood in both types is subject to rot and deterioration and the springs of the springloaded type are subject to rust and easy breakage, twist and disassemble and pinch the user.




Molded plastic clothespins and clamps are also available.




However, most are expensive or complicated in their construction and unreliable in their use and, when used as clothespins, allow the articles which they are intended to hold suspended from such as a clothesline to fall to the ground or floor.




BRIEF SUMMARY OF THE INVENTION




It is an object of the invention to provide a simple, inexpensive reliable, unitary, clothespin or multipurpose clamp which may be molded as an integral unit fabricated from a resilient plastic.




Another object is to provide such a clothespin or multipurpose clamp having a hairpin like configuration to include a loop allowing its suspension from a line or the like and a pair of pivotally related jaws which may be moved between a gripping,confronting position wherein the jaws are in contact with one another and an open position wherein the jaws are separated by the application or release of a squeezing pressure on the loop.

DETAILED DESCRIPTION OF THE INVENTION




A clothespin, or multipurpose clamp embodying the invention, generally indicated by the numeral


10


, is fabricated from a resilient plastic material such as high impact polystyrene or the like.




As shown in

FIG. 13

, clothespin or multipurpose clamp


10


is molded to provide an elongated, substantially rectangular integral unit having a substantially flat, outer face


12


and an inner face


14


which has a flat, central main body portion


15


, a first raised portion


16


extending inwardly from one of its free ends and communicating with one end of main body portion


15


, and a second raised portion


18


extending inwardly from its opposite free end and communicating with the opposite end of main body portion


15


.




First raised portion


16


includes, adjacent its outer end, a pair of spaced, parallel rounded projections


20


and


22


which extend across inner face


14


and are separated by a rounded depression


24


.




First raised portion


16


also includes, adjacent its inner end and one end of main body portion


15


, a combination locking/pivot member


26


having an annular crowned head


28


which extends across approximately one-half the width of inner face


14


and has an integral locking/pivot pin


30


disposed centrally thereof.




Locking/pivot pin


30


extends from a flat inner face


31


of crowned head


28


across inner face


14


of the clothespin and is split for a portion of its length as at


32


for purposes to appear.




A semi-circular depression


34


is provided in raised portion


16


immediately below locking/pivot pin


30


, also for purposes to appear.




Second raised portion


18


includes adjacent its outer end, a series of spaced, parallel, alternating rounded projections


36


and


38


and rounded depressions


40


and


42


which extend across inner face


14


.




Second raised portion also includes, adjacent its inner end, and the opposite end of main body portion


14


, an annular hub


44


which extends across approximately one-half the width of inner face


14


.




Hub


44


has a flat inner face


45


and is provided with a central through bore


46


of a diameter complemental to the outer diameter of locking/pivot pin


30


on locking/pivot member


26


of first raised portion


16


.




A semi-circular depression


47


is provided in raised portion


18


immediately adjacent hub


44


, also for purposes to appear.




In use, the opposite free ends of the clothespin or multipurpose clamp are grasped and raised portions


16


and


18


thereof are brought into a confronting, face-to-face relation, with main body portion


15


now having a curved configuration to form a loop


17


wherein the clothespin or multipurpose clamp assumes a hair-pin like or inverted U-shape as shown in

FIGS. 1-4

, and

FIGS. 14 and 15

.




At this time, the clothespin or multipurpose clamp now may be suspended from a clothesline C, or the like, with inner face


14


of main body portion


15


and loop


17


resting on the clothesline.




Raised portions


16


and


18


now may be inter-engaged, by being moved from the positions of

FIGS. 1 and 2

to the positions of

FIGS. 3

,


4


,


14


and


15


.




Body portions


16


and


18


are interengaged by deflecting raised portion


18


to a position behind raised portion


16


, exerting an inward pressure on outer face


12


in the direction of the arrows a so as to bring locking/pivot pin


30


of locking/pivot member


26


into alignment with through bore


46


of hub


44


and pressing with the fingers on the outer surfaces of crowned head


28


of raised portion


16


and hub


44


of raised portion


18


to snap locking/pivot pin


26


into through bore


46


, with split


32


in pin


26


permitting compression of the pin for easy passage through the bore.




Body portions


16


and


18


may be separated by simply reversing the above noted procedure.




In the closed configuration of

FIGS. 3 and 4

, hub


44


is disposed in semi-circular depression


34


of raised portion


16


, annular crowned head


28


is disposed in semi-circular depression


47


of raised portion


18


, and the flat inner faces


31


and


45


of crowned head


28


and hub


44


respectively are resting against each other as shown in

FIG. 12

, with raised portions


16


and


18


now forming confronting faces of a pair of pivotally interrelated jaws


48


and


50


for firmly gripping miscellaneous items.




In the closed configuration of

FIGS. 3 and 4

, rounded projections


20


and


22


of raised portion


16


of jaw


48


are pressing firmly against the inner face of raised portion


18


of jaw


50


with rounded projection


20


being disposed immediately above rounded projection


36


of portion


18


, and with rounded projection


22


pressing into rounded depression


42


of raised portion


18


.




With the clothespin or multipurpose clamp in the closed position of

FIGS. 3 and 4

, the lower ends of jaws


48


and


50


may be opened or spread apart as shown in

FIGS. 14 and 15

by applying a squeezing pressure to outer face


12


at pressure points b and c immediately above raised portions


16


and


18


respectively of the jaws to deflect loop


17


inwardly causing the lower ends of the jaws to move outwardly as the raised portions


16


and


18


pivot relative to each other relative to locking/pivot pin


30


.




When such squeezing pressure is released, the jaws return automatically to their closed, confronting positions.



Claims
  • 1. A unitary clothespin or multipurpose clamp molded from a resilient plastic material having a hair-pin like configuration comprising a loop, the loop terminating in a pair of confronting gripping jaws, and means permitting releasable, pivotal interconnection of the jaws whereby the jaws may be moved between a position whereby the jaws are not pivotally interconnected, thereby permitting suspension of the loop from a line or other support, and a position whereby the jaws are pivotally interconnected thereby precluding removal of the loop from the line or other support, and whereby when the jaws are pivotally interconnected, the jaws may be moved between a closed, gripping position in contact with each other for securely holding an article therebetween and an open, non-gripping position not in contact with each other for release of the article held therebetween upon the application or release of a squeezing compressive force upon the loop, wherein the means for releasably pivotally interconnecting the jaws is a locking/pivot member comprising a locking/pivot pin on one jaw and an apertured hub on the other jaw, the pin being slidably receivable in and removable from the aperture of the hub in the manner of a press fit, and wherein the pin is split for a portion of its length.
