ABSTRACT:
BACKGROUND OF THE INVENTION
1) Field of the Invention
The invention herein relates to an improved structure binder clip, wherein an insertion hole is punched in each of the two sides of the pincer section and, furthermore, an even number of oppositely facing limiter notches are formed along the inner circumference of the insertion hole and a rounded guide element is disposed in between each of the limiter notches, thereby providing for the rotation of the actuator rods along the rounded guide elements. The actuator rods have two ends bent to an appropriate angular degree and, furthermore, the resulting catch hooks extending from the bent sections formed on the two ends of the actuator rods, by means of the metallic resilience produced by pressing the two sides of the actuator rods inward, enable the catch hooks to become engaged into opposing pairs of limiter notches and, furthermore, the actuator rods remain fully pivotable while positioned in the limiter notches. As such, the improved structure binding clip of the invention herein does not adversely affect reading and writing and, furthermore, its die fabrication is simpler.
2) Description of the Prior Art
Conventional binder clips are utilized to hold printed or written note paper for reading so that the sheets of paper do not become scattered, temporarily lost, or cause a disorderly desktop.
In a conventional binder clip structure, as indicated in
FIG. 1
, the said binder clip
3
is comprised of a pincer section
51
having a hinge fold
511
formed by rolling the two binding ends outward to accommodate the respective insertion of the outwardly bent catch hook
521
formed at the two ends of the actuator rod
52
, which is typically accomplished by squeezing the two sides inward and relying on the tensile metallic reverse force to engage the catch hooks
521
of the actuator rod
52
into the hinge folds
511
and thereby conveniently installing the actuator rod
52
to achieve object binding capability; however, when actually utilized, the conventional binding clip structure is not as ideal as expected and the overall shortcomings may be concluded as follows:
1. Affects Reading and Writing
When sheets of printed material or note paper are held together by the binding clip, due to the forward and backward pivoting characteristics of the actuator rods
52
, the pincer section forms an excessive protuberance, with the left and right portions of the said sheets remaining uneven and unsecurable, which leads to positional writing difficulties; furthermore, if the actuator rods
52
are pivoted downward, although the pincer section is less obtrusive and writing is easier, the actuator rods
52
are pressed against the surface of the paper sheets and still affect reading and writing at this position.
2. Die Fabrication Difficulty
In the conventional binding clip, outwardly rolled hinge folds must be formed on the binding edges in order to fasten the actuator rods
52
to the pincer section
51
, with the bending into shape of the tubular hinge sections
511
involving the fabrication of a die for continuous press forming that requires additional time and, furthermore, is relatively more complex to finish.
In view of the said shortcomings, which lead to the various utilization inconveniences today, the inventor of the invention herein conducted extensive research, including repeated tests and refinements during that period, which culminated in the successful development of an improved structure binding clip that completely eliminates the said shortcomings of the conventional product and, furthermore, is capable of greater practical performance.
SUMMARY OF THE INVENTION
The primary objective of the invention herein is to provide an improved structure binding clip that does not affect reading and writing which is comprised of an insertion hole punched in each of the two sides of the pincer section and, furthermore, an even number of oppositely facing limiter notches are formed along the inner circumference of the insertion hole with a rounded guide element disposed in between each of the limiter notches and actuator rods each having their two ends bent to an appropriate angular degree and, furthermore, having catch hooks extending from the bent sections formed on the two ends, with the catch hooks capable of becoming engaged into opposing pairs of limiter notches and, furthermore, capable of rotation to any angular degree along the rounded guide elements between the limiter notches as well as remaining fully pivotable while positioned in the pincer section, thereby circumventing the excessive protuberance shortcoming of the pincer section in the conventional binding clip due to the fixed upward or downward pivoting range of its hinged actuator rods and, furthermore, reading and writing by the user is not impaired after the actuator rods are pivoted down.
Another objective of the invention herein is to provide an improved structure binding clip that allows simpler and more convenient fabrication. Since the pincer section and the actuator rods are engaged together in a manner that only requires the punching of the insertion holes in the pincer section and the appropriate bending of the actuator arms, it is not necessary to form the hinge folds on the pincer section of the conventional binding clip, a shortcoming that involves greater punch die difficulty during fabrication and as such, die fabrication is simpler in the improved structure binding clip of the invention herein.
To enable the examination committee to further understand the structure, innovations, function, and other practical objectives of the present invention, the brief description of the drawings below are followed by the detailed description of the embodiments.
