BACKGROUND OF THE INVENTION
1. Field of the Invention:
[0001] The present invention relates to everyday eating utensils and cutlery, and more particularly,
to an assemblable eating utensil that is actuated using the characteristic of elasticity
and gripping power.
2. Description of Related Art:
[0002] Portable assemblable and disposable eating utensils have become common in modern
life as people tend to eat out frequently. Moreover, a rising awareness of the potential
adverse effects of industrial chemicals used in disposable utensils has promoted the
use of reusable assemblable eating utensils for use while away from home.
[0003] Fig. 1 shows a conventional assemblable chopstick 1 that is often-seen and comprised
of two corresponding stick structures for easy assembling and carrying, wherein the
assembling structure is a screwing portion disposed at the end portions of the two
sticks to be assembled and disassembled by screwing to combine the two sticks together.
[0004] However, the dual-stick assembly has the drawback of troublesome operation in that
a user has to rotate one stick into the other several times in order to assemble the
two sticks together, and over-turning may easily cause damage to the threads of the
screwing portion.
[0005] In view of the drawback mentioned above, Taiwanese New Design Publication No. 00541924
discloses an assemblable chopstick as depicted in FIG. 2. As shown, the assemblable
chopstick 2 is comprised of a first section 20 and a second section 21, wherein one
end of the first section 20 is provided with an assembling hole 201 and a positioning
hole 202 connecting with the assembling hole 201, whereas the second section 21 includes
a protruding pillar 210 for inserting into the first stick 20, and the protruding
pillar 210 has a corresponding positioning protrusion 211. Using this design, the
protruding pillar 210 of the second section 21 can be inserted into the first stick
20 and then the positioning protrusion 211 can be slid into the assembling hole 201
to rotate the first and second sections and slide the positioning protrusion 211 into
the positioning hole 202, thereby assembling the two sections together to form an
assemblable chopstick.
[0006] In contrast to the known assemblable chopstick that is assembled by a screwing method,
the design of Taiwanese New Design Publication No. 00541924 has a relatively less
complex assembly method. However, the protruding pillar 210 of the second section
21 cannot be freely inserted into the first section 20 but requires using the positioning
protrusion 211 to slide into the assembling hole 201 for effective coupling. Therefore,
a user has to check first if the positioning protrusion 211 can be smoothly slid into
the assembling hole 201, thereby increasing difficulty in assembling, and it's possible
a user may need to try more than once in order to get the correct alignment or orientation
to combine the first section 20 with the second section 21.
[0007] Further, the positioning protrusion 211 and its positioning hole 202 are located
at a position close to the average holding position regularly used by users, resulting
in the protrusion 211 sometimes coming loose from the positioning hole 202 due to
the pressure of being held. Therefore, it is desirable to develop an assemblable eating
utensil, such as a pair of chopsticks, that has a simple yet reliable assembly structure
to improve on the prior techniques.
SUMMARY OF THE INVENTION
[0008] The present invention aims to eliminate the aforementioned drawbacks, and, as such,
a primary objective of the present invention is to provide an assemblable eating utensil
that has a simple assembly process.
[0009] Another objective of the present invention is to provide an assemblable eating utensil
that has an easy and clear assembly.
[0010] Another objective of the present invention is to provide an assemblable eating utensil
that provides for secure and reliable assembly.
[0011] In order to achieve the above and other objectives, the present invention provides
an assemblable eating utensil, comprising: an action member, such as a chopstick,
a spoon, a knife and a fork, etc., having a first gripping portion formed on one end
thereof; a body having a first positioning portion and a guiding portion disposed
on one end thereof; a moving member movably connecting the body and having a second
positioning portion corresponding to the first positioning portion, and one end of
the moving member is provided with a second gripping portion that is deformable for
elastically connecting with the first gripping portion, wherein the second gripping
portion becomes elastically deformed by contacting the guiding portion when the moving
member moves with respect to the body to grip on the first gripping portion; and an
elastic member disposed on the moving member at a position between the first and second
positioning portions, wherein the elastic member has the elasticity to permit the
second gripping portion to move towards and contact with the guiding portion, thereby
enabling the action member to be connected with the moving member and assembled with
the body to form an eating utensil.
[0012] In addition, one end of the moving member may further include a pressing head portion
protruding from the body to be pressed down to detach the second gripping portion
from the guiding portion so as to easily grip the first gripping portion, the inherent
elasticity of the second gripping portion allowing the first gripping portion to be
slightly gripped and then released by loosening the pressing head portion thereof,
such that the second gripping portion that is gripping on the first gripping portion
can return to the position of contacting the guiding portion by the elasticity of
the elastic member to grip the first gripping portion.
[0013] Compared to the assemblable chopsticks of the prior art that are assembled by a screwing
method, the assemblable eating utensil of the invention is implemented by pressing
and releasing the pressing head portion thereof to thereby grip and detach the first
gripping portion from the second gripping portion to achieve rapid assembly of the
action member and the body.
[0014] In one preferred embodiment, the moving member is a rod or stick, and the body is
a sheath for covering the rod body, the guiding portion being disposed at one end
of the sheath and the second gripping portion being movable for moving in and out
of the sheath, and the elastic member is a spring around the moving member, and the
first positioning portion and the second positioning portion are protruding stairs
disposed in the sheath and on the rod body respectively.
[0015] The guiding portion is a passageway extending from an opening formed at one end of
the sheath inwardly at tapering angles toward the sheath. The second gripping portion
is an elastic block having a narrow opening/crack and the external portion thereof
is also a taper-shaped structure for passing in and out of the sheath. The second
gripping portion is guided by the guiding portion to become elastically deformable
as a result of the characteristic of the guiding portion having an inner tapered-shape
toward the sheath. The first gripping portion may be a protrusion disposed at one
end of the action member to be freely assembled and disassembled on the second gripping
portion when the second gripping portion detaches from the guiding portion.
[0016] Compared to the known assemblable chopsticks that require accurate positioning to
facilitate smooth insertion and rotation for assembling, the assemblable eating utensil
of the invention utilizes the action member to assemble and disassemble the first
and second gripping portions, which can be completed at one time without the burden
of positioning.
[0017] Also compared to prior techniques in which positioning points and holes are required
for assembling and thus often result in insufficient stability, the assemblable eating
utensil of the invention is implemented by combining the first and second gripping
portions in the body, i.e. the sheath, thereby preventing easy accidental detachment
caused by inadvertent contact, and, also, the assembly of the second gripping portion
that is restricted by the guiding portion gripping on the first gripping portion is
firm and cannot be easily broken.
[0018] Moreover, the second gripping portion may be integrally formed with the moving member
or connected by screwing to the moving member, wherein the second gripping portion
may be screwed to the moving member to more tightly assemble the action member on
the body when the second gripping portion retracts back to the body, thereby connecting
the pressing head portion with the body by a screwing action to increase the visual
appeal.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0020] The present invention is described in the following so that one skilled in the pertinent
art can easily understand other advantages and effects of the present invention. The
present invention may also be implemented and applied according to other embodiments,
and the details may be modified based on different views and applications without
departing from the spirit of the invention.
[0021] Referring to Fig. 3 and Fig. 4, the assemblable eating utensil of the invention includes
an action member 32 with a first gripping portion 320 formed on one end thereof; a
body 31 having a first positioning portion 310 and a guiding portion 311 disposed
on one end thereof; a moving member 30 movably connecting the body 31 and having a
second positioning portion 302 corresponding to the first positioning portion 310,
and one end of the moving member 30 is provided with a second gripping portion 303
for elastically connecting with the first gripping portion 320, wherein the second
gripping portion 303 becomes deformable by contacting the guiding portion 311 when
the moving member 30 moves with respect to the body 31 to grip the first gripping
portion 320; and an elastic member 33 disposed on the moving member 30 at a position
between the first and second positioning portions, wherein the elastic member 33 has
elasticity to allow the second gripping portion 303 to move towards and contact with
the guiding portion 311, enabling the action member 32 to be connected with the moving
member 30 and assembled with the body 31 to form an assemblable eating utensil.
[0022] The action member 32 is an eating utensil such as a chopstick, a spoon, a knife and
a fork, etc. One end of the moving member is further comprised of a pressing head
portion 304 that protrudes from the body 31 to be pressed down to thereby detach the
second gripping portion 303 from the guiding portion 311 to easily grip the first
gripping portion 320, and the inherent elasticity of the second gripping portion 303
allows the first gripping portion 320 to be slightly gripped and then released by
loosening the pressing head portion 304 thereof, such that the second gripping portion
303 connecting with the first gripping portion 320 can return to the position of contacting
the guiding portion 311 by the elasticity of the elastic member 33 to grip the first
gripping portion 320.
[0023] Compared to the complex screw-assembled chopsticks used in the prior art, the assemblable
eating utensil of the invention is assembled by pressing and then releasing the pressing
head portion 304 thereof to grip and detach the first gripping portion from the second
gripping portion to achieve a rapid assembly of the action member 32 and the body
31.
[0024] The moving member 30 may be a rod or stick and the body 31 may be a sheath for covering
the rod member; the guiding portion 311 is disposed at one end of the sheath and the
second gripping portion 303 is movable lengthwise within the sheath; the elastic member
33 is a spring around the moving member 30, and the first positioning portion 310
and the second positioning portion 302 are protruding stairs disposed in the sheath
and on the rod member respectively. The guiding portion 311 is a passageway extending
from an opening formed at one end of the sheath inwardly with tapered angles going
inwards. The second gripping portion 303 is an elastic block having a narrow opening/crack
and the external portion thereof is also a taper-shaped structure for moving in and
out of the sheath; the second gripping portion 303 is guided by the guiding portion
311 to become elastically deformable by the characteristics of the guiding portion
311 that is formed with tapered angles going inwards from the opening. The first gripping
portion 320 may be a protrusion disposed at one end of the action member 32 so as
to be freely assembled and disassembled on the second gripping portion 303 when the
second gripping portion 303 detaches from the guiding portion 311.
[0025] Compared to the conventional assemblable chopsticks that require accurate positioning
to facilitate smooth insertion and rotation for assembling, the assemblable eating
utensil 3 of the invention utilizes the action member 32 to assemble and disassemble
the first gripping portion 320 from the second gripping portion 303, and such assembly
can be completed at one time without the burden of accurate positioning.
[0026] Also compared to prior techniques in which positioning points and holes are required
for assembling and often result in insufficient stability, the assemblable eating
utensil of the invention is assembled by gripping the first gripping portion 320 and
the second gripping portion 303 in the body, i.e. the sheath, thereby preventing detachment
that is easily caused by inadvertent contact by the user. Also, the assembly of the
second gripping portion 303 that is restricted by the guiding portion 311 connecting
with the first gripping portion 320 is firm and cannot be easily broken.
[0027] Moreover, the second gripping portion may be integrally formed with the moving member
or connected by screwing to the moving member, wherein the second gripping portion
may be screwed to the moving member to more tightly assemble the action member on
the body when the second gripping portion retracts back into the body, thereby connecting
the pressing head portion with the body by a screwing action to increase the visual
appeal.
[0028] Further, the implementation of the moving member 30 and the body 31 can be switched
with one another, thus making the guiding portion 311 a tapered object formed at an
end of the body 31, while the first gripping portion 320 is an elastic covering body
covering the second gripping portion 303, the configuration being assembled by first
entering the second gripping portion 303 into the first gripping portion 320, and,
when it retracts back to contact the guiding portion 311, the second gripping portion
303 is forced to open and further grasp the first gripping portion 320.
[0029] Additionally, in order to ensure that the moving member 30 can smoothly slide longitudinally
to connect with the body 31 and to enhance the positioning effect between the elastic
member 33 and the body 31, a stopping member 34 is further formed in this embodiment
at a position between the elastic member 33 and the first positioning portion 310,
wherein the stopping member 34 may be a ring for surrounding the moving member 30,
the inner diameter and outer diameter of the ring respectively corresponding to the
outer diameter of the moving member 30 and the inner diameter of the body 31.
[0030] Moreover, the second gripping portion 303 can be integrally formed with the moving
member 30 or connected to the moving member 30 by a screwing action, as shown in Fig.
4, where an embodiment of the second gripping portion 303 connecting with the moving
member 30 by a screwing method is depicted, making each component of the assemblable
eating utensil detachable for easy maintenance and replacement when required. Further,
extra threads on the screw may be added and preformed between the second gripping
portion 303 and the moving member 30, so that when the second gripping portion 303
retracts back into the body 31, the second gripping portion 303 can be further screwed
onto the moving member 30 to provide for tight connection between the motion member
32 and the body 31, while the pressing head portion 304 can be pressed down to connect
with the body 31 to make the appearance of the assemblable eating utensil of the present
invention more appealing.
