Abstract
A ratchet clip is comprised of first and second jaws hinged together at proximal ends. A serrated member is attached to the proximal end of the first jaw. Teeth on the serrated member are angled against the opening direction of the second jaw. An intermediate portion of a ratchet lever is hinged to the second jaw. An inner portion of the lever is engaged against the teeth on the serrated member, and an outer portion is positioned through a hole in the second jaw. A spring positioned between the proximal ends of the jaws bias the distal ends of the jaws away from each other. One end of the spring is arranged to bias the outer portion of the lever outward, and the inner portion against the serrated member. When the lever is depressed, its inner portion is disengaged from the serrated member to allow the jaws to open.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates generally to clips with hinged arms.




2. Prior Art




Clips are commonly used for securing two or more items together. A typical clip is comprised of two jaws hinged together at proximal ends. A spring connected between the jaws bias the distal ends of the jaws together for gripping. Prior art clips typically rely solely on spring pressure to keep the jaws clamped together. The springs have limited power because they must be weak enough for a user to open the jaws. Therefore, such clips may lose grip if the items being held are pulled with moderate force.




OBJECTS OF THE INVENTION




Accordingly, objects of the present ratchet clip are:




to removably attach itself to a supporting device such as clothing;




to grip an item securely between its jaws;




to be easily opened by a user;




to prevent being spread apart once the jaws are closed around an item;




to be easily adjustable for gripping items of different sizes; and




to easily release the item quickly without being detached from the supporting device.




Further objects of the present invention will become apparent from a consideration of the drawings and ensuing description.




BRIEF SUMMARY OF THE INVENTION




A ratchet clip is comprised of first and second jaws hinged together about a first axle at proximal ends. A serrated member attached to the first jaw is curved about the first axle. Teeth on the serrated member are angled toward the distal ends of the jaws. An intermediate portion of a ratchet lever is hinged about a second axle to the second jaw. An inner portion of the lever is engaged against the teeth on the serrated member, and an outer portion is positioned through a hole on the second jaw. A spring is positioned between the proximal ends of the jaws bias the distal ends of the jaws away from each other. One end of the spring is arranged to bias the outer portion of the lever outward against an edge of the hole. When the lever is pressed, it inner end is disengaged from the serrated member to allow the jaws to open. When the lever is released, its inner end is engaged against the serrated member to lock the jaws in position.

DETAILED DESCRIPTION OF THE INVENTION




FIG.


1


:




A preferred embodiment of the ratchet clip is shown in a perspective view in FIG.


1


. It is comprised of first and second jaws


10


and


11


hinged together about a first axle


12


at proximal ends


13


and


14


. A serrated member


15


is positioned between the proximal ends of jaws


10


and


11


. Serrated member


15


is fixed to first jaw


10


and curved about first axle


12


. Teeth


16


on serrated member


15


are angled against the opening direction of second jaw


11


. An intermediate portion


17


(

FIG. 2

) of a ratchet lever


18


is hinged to second jaw


11


about a second axle


27


. A serrated inner portion


19


(

FIG. 2

) of lever


18


is positioned between the proximal ends of jaws


10


and


11


, and engaged against teeth


16


on serrated member


15


. An outer portion


20


of lever


18


is positioned through a hole


21


in second jaw


11


. Gripping members


22


and


23


are hinged to the distal ends of jaws


10


and


11


for providing self-adjusting gripping surfaces when jaws


10


and


11


are wide open.




A coil spring


24


is positioned between the proximal ends of jaws


10


and


11


. A first end


25


of spring


24


is arranged to bias outer portion


20


of lever


18


outward and inner portion


19


of lever


18


against serrated member


15


. Since lever


18


is attached to second jaw


11


, second jaw


11


is also biased outward by spring


24


. A second end


26


of spring


24


is arranged to bias against the inner side of first jaw


10


. The distal ends of jaws


10


and


11


are thus biased away from each other.




A spring clip


28


is attached to first jaw


10


by a ring


29


connected to loop


30


(

FIG. 2

) attached to first jaw


10


. Spring clip


28


may be hooked to any supporting device, such as clothing, backpacks, tool bags, etc. The clip is usable for gripping items between its jaws, such as gloves, to the supporting device, such as clothing. It can easily and quickly release the items without being detached from the supporting device.




FIGS.


2


-


5


:




In

FIG. 2

, jaws


10


and


11


are fully closed. Inner portion


19


of lever


18


is engaged against serrated member


15


. Teeth


16


on serrated member


15


are angled against the opening direction of second jaw


11


. Inner end


19


of lever


18


cannot slide against the direction teeth


16


are angled. Therefore, inner portion


19


of lever


18


is locked against serrated member


15


. Since serrated member


15


is fixed to first jaw


10


, second jaw


11


is also locked relative to first jaw


10


so that they cannot be accidentally spread apart. In

FIG. 3

, the outer portion of lever


18


is depressed and its inner end is disengaged from serrated member


15


, and jaws


10


and


11


are free to spread open under the pressure of spring


24


.




In

FIG. 4

, jaws


10


and


11


are opened to a desired position while lever


18


is still depressed. In

FIG. 5

, lever


18


is released to engage its inner portion against serrated member


15


and lock jaws


10


and


11


in position. Jaws


10


and


11


may be opened to any position within a range determined by teeth


16


of serrated member


15


. Jaws


10


and


11


cannot open any further when it is locked in a selected position. Jaws


10


and


11


can be tightened together by pressing them closer. Inner portion


19


of lever


18


are arranged to slide past teeth


16


to allow second jaw


11


to be pivoted towards first jaw


10


. When jaws


10


and


11


are opened, gripping members


22


and


23


are free to pivot into parallel position for improving grip.




SUMMARY AND SCOPE




Accordingly, the present ratcheting clip can grip an item securely between its jaws. It is easily opened by pressing the lever. It cannot be accidentally loosened once the jaws are closed around the item. It is also easily adjustable for gripping items of different sizes.




Although the above description is specific, it should not be considered as a limitation on the scope of the invention, but only as an example of the preferred embodiment. Many variations are possible within the teachings of the invention. Therefore, the scope of the invention should be determined by the appended claims and their legal equivalents, not by the examples given.
