Description




BACKGROUND OF THE INVENTION




1) Field of the Invention




The invention herein relates to a tool box drill bit retainer that provides for the containment of different diameter drill bits inside the tool box, the primary application of which is keeping larger size drill bits within the drill bit recess of the tool box. The improved structure of the drill bit retainer effectively enhances the orderly securing of drill bits in the tool box and increases product practicality.




2) Description of the Prior Art




In a conventional tool box drill bit holder, referring to

FIG. 1

,

FIG. 2

, and

FIG. 3

, the said conventional tool box


10


has disposed within a plurality of clips that hold a series of different diameter drill bits; larger size drill bits are grouped into a drill bit recess


11


of the conventional tool box


10


and a drill bit retainer


20


is fitted into an insertion hole


12


in the tool box


10


to keep the larger drill bits forcefully contained within the drill bit recess


11


, wherein the conventional drill bit retainer


20


consists of a fan-shaped push plate


21


extending laterally from its upper edge and a locating column


22


projecting downward vertically, with the said locating column


22


having a flat face


23


formed along one side; the insertion hole


12


of the said tool box


10


is compatible in internal shape with the outer profile of the locating column


22


and has flat face along one side; the conventional tool box


10


, as structurally described above, is capable of keeping larger size drill bits in position, but since tool boxes are frequently carried and moved about, the drill bit retainer


20


loosens in the tool box


10


insertion hole


12


, causing the larger size drill bits to become scattered among the other drill bits inside the tool box


10


, resulting in wear and damage from collisions.




In view of the said shortcomings in the structural technology of the conventional product that await improvement, the inventor of the invention herein, based on experience gained from engagement in the related industries and actual design experience, devised an original solution that culminated in the successful development of the improved tool box drill bit retainer of the invention herein.




SUMMARY OF THE INVENTION




The objective of the invention herein is to provide a tool box drill bit retainer that effectively stabilizes the containment of drill bits in the tool box and increases product practicality.




To enable a further understanding by the examination committee of the advantages, objective, and function of the invention herein as well as how the said objective is achieved, the brief description of the drawings below is followed by the detailed description of the most preferred embodiment.

DETAILED DESCRIPTION OF THE INVENTION




The invention herein is a tool box drill bit retainer; referring to

FIG. 4

,

FIG. 5

,

FIG. 6

, and

FIG. 7

, the said tool box


30


has arrayed within a plurality of clips that hold a series of different diameter drill bits; larger size drill bits are grouped into a drill bit recess


31


of the tool box


30


and a drill bit retainer


40


is fitted into an insertion hole


32


in the tool box


10


to keep the larger drill bits forcefully contained within the drill bit recess


31


, wherein the said drill bit retainer


40


consists of a fan-shaped push plate


41


extending laterally from its upper edge and a locating column


42


projecting downward vertically, with the said locating column


42


having a flat face


43


formed along one side and, furthermore, a catch block


44


protrudes laterally along the lower half of the flat face


43


; in addition, the internal shape of the insertion hole


32


in the said tool box


30


is compatible with the exterior profile of the locating column


42


and a stop block


33


having a thickness of approximately


2


mm protrudes laterally from the top edge of the said insertion hole


32


.




The invention herein is utilized to secure larger size drill bits that are grouped into the tool box


30


drill bit recess


31


and the drill bit retainer


40


is fitted into the tool box


10


insertion hole


32


; with the centers of the drill bit retainer


40


and the insertion hole


32


in axial alignment, the catch block


44


on the locating column


42


of the drill bit retainer


40


is rotated in the tool box


30


until it engages the stop block


33


situated at the top edge of the insertion hole


32


which effectively secures the push plate


41


of the drill bit retainer


40


against the larger size drill bits. To obtain a larger sized drill bit from the tool box


30


, the drill bit retainer


40


is rotated in the tool box


30


to disengage the catch block


44


from the stop block


33


at the top edge of the insertion hole


32


, thereby enabling the removal of the drill bit retainer


40


and access to the larger drill bits.




In summation of the foregoing section, since the invention herein is capable of achieving the claimed utilization objective and the disclosed structure provides for greater practical value and, furthermore, no identical or similar product has been observed on the market, the present invention is submitted to the examination committee for review and the granting of the commensurate patent rights.



Claims
  • 1. A tool box having a drill bit retainer, comprising:a tool box having an upper side, said upper side having (a) a drill bit recess formed therein for receiving drill bits of predetermined sizes, and (b) an insertion hole disposed adjacent said drill bit recess, said insertion hole having a stop block extending from an inner wall thereof adjacent an upper end of said insertion hole; a plurality of clips secured to said upper side of said tool box for retaining a plurality of drill bits of varying sizes; and, a drill bit retainer releasably coupled to said tool box, said drill bit retainer having a longitudinally extended location column, a push plate extending laterally from a one end of said location column, and a catch block formed adjacent an opposing end of said location column, said location column being rotatably received in said insertion hole, wherein said drill bit retainer is rotated within said insertion hole until said catch block is engaged by said stop block to thereby direct said push plate into retaining engagement with drill bits in said drill bit recess, and is reversibly rotated to disengage said catch block from said stop block and withdrawn from said insertion hole to provide access to the drill bits in said drill bit recess.
