Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention generally relates to a drill bit
suspension structure, which provides complete enclosure of a
working portion of a drill bit and allows for vertical suspension
for exhibition, where a package arrangement that realizes complete
enclosure of the working portion of the drill bit is provided and a
bottom of the package case forming an insertion tube or supporting
a retention seat for assisting positioning of the drill bit in a
suspended condition, so that the drill bit can be set in an erected
condition for secure suspending package to realize aesthetics,
security, and practicability of suspending exhibition.
DESCRIPTION OF THE PRIOR ART
[0002] Display and sale of a drill bit are often done with a
suspending enclosure form that is made of a transparent case or
shell to provide a completely enclosed package. As shown in FIGS. 6
and 7, a transparent hollow package case body 30 is provided, which
has a predetermined length, normally slightly greater than the
length of a packaged drill bit like tool piece 31, and is used in
combination with a cap 32 or a hanging plate 33 to seal and close
the package, so as to safely receive and store the tool piece 31
therein. However, the whole package is nothing but simply placing
the drill bit like tool piece in the package case. For a drill bit
like tool piece that is of a substantial length, there must be such
a situation that the tool piece is received in an inclined fashion,
so that whether the tool piece is disposed in one direction or the
other direction, the tool piece is placed in an inclined fashion
and the spiral cutting edge of the drill bit is inevitably
subjected to physical contact and thus potential risk of damage.
Such a package design that allows for arbitrary placement can
hardly provide and ensure protection and may cause such a trouble
of inconsistency in product exhibition. These are problems that are
hard to overcome. Further, a consumer is only allowed to make
visual observation of the product through the transparent case or
package shell. It is difficult to correctly inspect the product due
to the inclined deposition of product and also due to light
reflection caused by the transparent case. It has long been a
challenge of the industry to overcome the problems associated with
the existing packages that are unsafe and impractical and to
provide a dill bit suspension device that allows for true
convenience of suspended exhibition of drill bit like tool pieces
and at the same time realizes theft resistance and easy inspection
for consumers.
SUMMARY OF THE INVENTION
[0003] In view of the above problems of the existing suspending
packages that do meet the needs for package safety and aesthetics
of exhibition and use, the present invention aims to provide an
improved drill bit suspension structure, which adopts such an
arrangement that an insertion tube or a retention seat is formed on
a bottom of a package case to realize easy positioning and packing
a cutting section of drill bit to thereby meet the needs for safe
packaging and easy inspection of vertically suspended drill bit
like tool pieces and effectively improve the insufficiency of
practicability of the existing suspension means for drill bit like
tool pieces.
[0004] An objective of the present invention is to provide a drill
bit like tool piece with vertical disposition suspension package
that ensures safe exhibition and use, so as to realize reliable
protection and safety of cutting edge of drill bit like tool piece
and aesthetics, security, and theft resistance for suspension
exhibition of the bit like tool piece, as well as easy access,
inspection, and use of the packaged product.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] The following descriptions are exemplary embodiments only,
and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0015] The present invention provides a drill bit suspension
structure, which provides a dill bit like tool piece package that
allows for easy suspension and exhibition of the package and ready
inspection of the packaged product. As shown in FIGS. 1-3, the
suspension structure comprises a package case 10 that is provided
for product insertion and packaging. For easy inspection, it is
made by a transparent packaging material in the form of a hollow
box, which has a length that is slightly greater than the cutting
edge portion of a drill bit like tool piece 20 to be packaged. The
case has a bottom board 11 that forms centrally a through hole. The
through hole has a circumferential rim that projects inward or
outward the case to form an insertion tube 12 of a predetermined
length. The case has an open top, which may form, for the purpose
of coupling, apertures or recesses 13 in for example opposite side
walls of the tetragonal case as shown in the drawing, so that a cap
like cover 14 may be coupled thereto in a snap-in fashion to close
and cover and fix to the top opening of the case 10 to realize
package safety The cover 14 has a top forming a suspension board 15
that extends therefrom for suspending exhibition. To use the
package container, the drill bit like tool piece 20 to be packaged
is inserted, in a revered fashion, into the package, whereby the
long stem like shank 21 of the drill bit like tool piece 20
directly fit into the insertion tube 12 and partially extending
outside the case 10 by a predetermined length. The drill bit like
tool piece 20 is thus in a naturally erected condition, where the
cutting edge portion 22 of the drill bit inserted into the case 10
is set upright, instead in an inclined fashion as the existing ones
do. There will be no concern about impacting and abrading against
the cutting edge. As such, the purpose of safe suspension and
package is achieved.
[0016] If desired for practical applications, the drill bit like
tool piece 20 can be packaged in the form shown in FIGS. 4 and 5,
wherein, based on the circumferential configuration of the case 10,
a retention seat 16 that provides a predetermined raised elevation
is provided and forms centrally a bore 17 for insertion, whereby a
conic-shaped bit tip 23 of the drill bit like tool piece 20 can be
directly set into the bore 17, for example through threading
engagement therebetween, to fix and combine together. The drill bit
like tool piece 20 is thus inserted in and held on the retention
seat 16 in advance and the retention seat 16 is disposed into the
lower end portion of the case 10 to set the drill bit like tool
piece 20 in an erected and packaged condition. The retention seat
16 may be alternatively formed in combination with and raised from
the bottom board of the case, whereby the bit tip 23 can be
disposed to insert into and fix to the bore 17 that is formed above
the board. This may then be combined with closure realized by the
cover 14 to allow the suspension board 15 to readily suspend the
drill bit for suspending exhibition.
[0017] The vertical suspension structure according to the present
invention is characterized in that the unique insertion and
retention arrangement provided on the bottom of the case 10, namely
the insertion tube 12 that is formed through a central portion of
the case 10 or the retention seat 16 that forms the central bore
17, the tool piece 20 inserted therein can be held in an erected
condition to realize an inserted packaging and an additional
efficacy of vertical positioning and protection of the inserted
tool piece 20 can be realized to protect the tool piece 20, when
packaged for suspension, from impact, shifting, and damaging. The
reversely inserted shank 21 is allowed to extend outside the case
10 for hand touching and holding and rotating the tool piece 20 to
realize effective inspection of the cutting edge portion 22 of the
drill bit. The suspension package according to the present
invention makes the suspending exhibition package case aesthetic in
the outside appearance and reduces the package length of the case,
due to the reverse insertion, so as to substantially reduce the
package volume. The whole suspension package of drill bit can be
molded easily to lower down the manufacturing cost and allows for
easy insertion of the packaging of the drill bit like tool piece
20. Thus, the packaging of the tool piece 20 is simplified. In view
of such a suspension package case structure, the present invention
is advantageous for being economic and providing practical use of
safety and convenience, and shows a milestone innovation of
packaging for drill bit like tool piece 20 of this kind.
[0018] The top opening of the case 10 allows the cover 14 to couple
thereto in a forcible snap-in fashion through the engagement
recesses 13 or apertures formed in side walls of the case opening
for securely fixing and positioning. The top of the cover 14 forms
the suspension board 15 extending therefrom to allow the package
case to be easily suspended for exhibition. The shank of the
reversely inserted drill bit like tool piece 20 naturally depends
and projects down below the case 10 to allow a consumer to tough
with hand for inspection. The insertion tube 12 that is provided
for insertion and positioning can be directly formed on the bottom
board in a unitary fashion, or an alternative design of a separate
lining board may be adopted, where the lining board forms centrally
an insertion tube integrally extending therefrom and the lining
board is then disposed in the case 10, this being in resemblance to
the independent arrangement of the retention seat 16 and achieving
the same result of insertion and positioning. This is thus
considered a simple modification and is believed belonging to the
scope of the present invention. The suspension device according to
the present invention allows a drill bit like tool piece 20 to be
vertically disposed by the gravity thereof. This ensures stability
of suspending exhibition of the tool piece and surely sets the tool
piece 20 in vertical suspension for exhibition to realize aesthetic
and secure suspending exhibition of the tool piece. The present
invention is an innovate design for packaging and suspending of
drill bit and provides the advantages of secure suspension and use,
which is an novel and practical design of drill bit suspending
device of this kind.
[0019] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0020] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
