[0001] The present invention relates to a portable dining utensil, and more particularly
to a loopable and wearable dining utensil, for example a chopstick, a fork or a spoon.
According to various connecting profiles, the multiple dining utensils can form a
bracelet, necklace, belt or an ornament of handbag or hand-held mobile device.
Description of the Prior Art
[0002] As well known to those skilled in the art, Yu-Chiuan Chen teaches a loopable and
wearable dining utensil in
U.S. PAT. NO. 8,176,751, a previous creation of the present invention, granted on May 15, 2012. FIGs. 1A
through 1B are views illustrating the loopable and wearable dining utensil of Chen.
As shown in FIG. 1A, a chopstick 300 includes a rigid function portion 301, a holder
303 and a flexible connector 118. The rigid function portion 301 has a chopstick terminating
at one end in a rounded tip which is intended to engage portions of food and the rounded
tip also serves as a male linker 302. The opposite end of the rigid function portion
301 has a first linking part 116 which is of a rectangle cross-section. The holder
303 is intended to hold the chopstick 300. One end of the holder 303 serves as a female
linker 306 used for linking with the male linker 302, and the opposite end has a second
linking part 112 used for linking with the first linking part 116. The flexible connector
118 intended to connect the rigid function portion 301 and the holder 303 has a flexible
member 122 and a stopper 124. The chopstick 300 forms a loop when the male linker
302 is engaged with the female linker 306 of the holder 303, as shown in FIG. 1B.
The chopstick 300 forms a normal used chopstick which has the flexible connector 118
received in the inner of the chopstick when the first linking part 116 is engaged
with the second linking part 112 of the holder 303.
[0003] From the above description, the features of
U.S. 8,176,751 enable dining utensils to be wearable by using simple structure and easy assembly
to form a bracelet, necklace, belt or an ornament of handbag or hand-held mobile device.
Second, since a carrying case is excluded, a carrying volume is reduced and burden
of user is also relieved. Furthermore, dining utensils as personal ornaments triggers
user to bear when eating outside on weekdays, which is sustainable to our environment.
[0004] The loopable and wearable chopstick 300 is easily carried and wearable as ornaments.
However, the wearable chopstick is very loose. This is that the shape and size of
the wearable chopstick could not be adjusted and fixed due to the configuration of
the flexible connector 118. And, the beauty of ornaments can not be shown. Moreover,
as the flexible connector is a wire or a chain, the second linking part 112 and first
linking part 116 easily get dirt accumulation when the chopstick 300 forms a loop-shaped
ornament. In addition, the flexible connector 118 is not easily to receive in the
inner of the chopstick 300 when forming a normal used chopstick.
SUMMARY OF THE INVENTION
[0005] An objective of the present invention is to solve the above-mentioned problems and
to provide a wearable dining utensil, for example a chopstick, a fork or a spoon,
characterized by a shapeable connector and easy assembly to form a bracelet, necklace,
belt or an ornament of handbag or hand-held mobile device. The shapeable connector
can be adjusted and fixed when forming a loop-shaped ornament.
[0006] The present invention achieves the above-indicated objective by providing a wearable
dining utensil. The wearable dining utensil comprises a rigid function portion for
engaging food, a holder for holding the dining utensil, and a shapeable connector
for connecting the rigid function portion and the holder. The rigid function portion
has a tip terminating at one end for engaging food, wherein the tip also serves as
a male linker and the opposite end of the rigid function portion has a first linking

portion 463. The bendable portion 463 can be bent into a desired shape and can be
recovered with a reverse force by hands. A fifth linking part 477 is used for linking
with the second linking part 412. A central part of the fifth linking part 477 has
an outlet 442 whose shape is adopted to fit the bendable portion 463. The outlet 442
is used for linking with the fourth linking part 475 and can get the bendable portion
463 moving through the middle part 414 of the holder 403 when the fifth linking part
477, the shapeable connector 418 and the second linking part 412 are linked. A stopper
424 is formed at one end of the bendable portion 463 to prevent the bendable portion
463 from separating off the fifth linking part 477. A transparent silicone sheath
499 with a thickness of 0.02 to 0.5 mm forming a protective cover upon the rigid function
portion 401 is added. The protective cover 499 is a replaceable consumable. Silicone,
sustainable to high heat-resistant about 190 °C, can be used in the dishwasher and
boiled disinfections to ensure health.
[0012] Two cavities 408 for engaging with the male linker 402 are formed in the female linker
406 of the holder 403. Dents 404 for locking with knots 410 which are formed on each
middle site of sidewalls of the cavities 408 are formed on the tips of the male linker
402. A shape of the cavities 408 is adopted to fit the male linker 402 resulting in
matched coupling formed by the cavities 408 and the male linker 402. Cavities 408
can be formed in the bottom side of female linker 406 and can be four sides closed
cavities. One rigid central portion 490 can be added between the rigid function portion
401 and the holder 403 of the fork 480 as shown in FIG. 2. Two shapeable connectors
418 are used to link the rigid central portion 490 with the rigid function portion
401 and the holder 403. The rigid central portion 490 has a sixth linking part 479
used for linking with the fifth linking part 477, and a seventh linking part 489 used
for linking with third linking part 476. The sixth linking part 479 formed at one
end of the rigid central portion 490 has the same structure and function to the second
linking part 412. The seventh linking part 489 has the same structure and function
to the first linking part 416. It is understood that the rigid central portion 490
is used to increase a length of the fork 480.
[0013] The fork 480 forms a loop with a desired size and shape when the male linker 402
is engaged with the female linker 406 of the holder 403, as shown in FIG. 3. Additionally,
the shape and size of the loop-shaped fork 480 can be adjusted and fixed through the
bendable portions 463. The fork 480 forms a normal used fork which has the two shapeable
connectors 418 received in the inner of the fork 480 when each the fourth linking
part 475 is engaged with each the outlet 442, as shown in FIG. 4. Furthermore, the
rigid central portion 490 is an optional element. A loop-shaped fork 400 without a
rigid central portion 490 is an essential implementation of the claimed invention,
as shown in FIG. 5.
[0014] FIG. 6 is a perspective view of the first linking part, second linking part and the
shapeable connector. As shown in FIG. 6, the first linking part 416 has a female thread,
and the third linking part 476 has a male thread; a connection manner of these two
components is a connection of thread. An aspect of a connection manner of the fifth
linking part 477 and the second linking part 412 is also a connection of thread. A
cross-section shape of the fourth linking part 475 and of the outlet 442 is a circle,
ellipse, square or rectangle, and an external diameter of the fourth linking part
475 is about equal to an internal diameter of the outlet 442 causing a tight connection.
The tight connection can prevent dirt accumulation when the fork 480 forms a normal
used fork. A washer can be coupled in the inner periphery of the outlet 442 or the
outer periphery of the fourth linking part 475. Functions of the washer are to increase
marginal adaptability between the bendable portions 463 and the fourth linking part
475 as well as reduce the friction effect.
[0015] The bendable portion 463 is formed with a metal or an alloy with the properties of
ductility and malleability, and fixed on the fourth linking part 475 via use of metal
riveting or welding. The bendable portion 463 can move axially relative to the outlet
442, and possesses ductility resulting in shapes and sizes of the loop-shaped fork
being adjusted and fixed. For example, to adjust different curvatures, the bendable
portion 463 can change the size of the loop-shaped ornament. The bendable portion
463 is made of a ductile metal or alloy, noble metals using for ornaments or dining
utensils, such as gold, silver, platinum, tin, titanium and stainless steel. One original
property of metal is having a plastic deformation ability at room temperature, and
it can be cold worked. The selected metal specimens must be no cracks or delamination
occurs during cold bending test. One tensile strength σ b of the selected metal of
the bendable portion is between 40 MPa and 1000 MPa; elongation δ is greater than
7%. The bendable portion 463 can be bent into a desired shape and can be recovered
with a reverse force by hands. A desired shape can be done when the bending force
is between 0.5 and 10 kgf. A cross-section area can be obtained from mechanical prosperities
testing results of the selected metal, and thus the requirement of the 0.5 to 10 kgf
bending force can be achieved. As can be seen from FIG. 6, the rigid function portion
401, the holder 403 and the shapeable connectors 418 of the present invention are
each independent. Therefore, if necessary, each of the parts can be replaced and various
types of the rigid function portion 401 or the holder 403 can be selected.
[0016] FIG. 7 is a perspective view of the fifth linking part and the shapeable connector.
As shown in FIG. 7, the shapeable connector 418 includes a bendable portion 486 whose
function is the same as the bendable portion 463. A body of the bendable portion 486
can be ellipse or square with serrated and can be easily adjusted to a desired shape.
The bendable portion 486 is covered with a soft silicone, rubber, polyethylene or
polypropylene sleeve 482 for increasing marginal adaptability with the outlet 442
of the fifth linking part 477 as well as for reducing the friction effect. The bendable
portion 486 can also be formed with the commonly used copper or aluminum alloy. The
bendable portion 486 is similar to a commonly used electrical copper wire with 1.6
or 2.0 mm diameter and covered with a soft polymer rust proof layer or insulating
layer. The sleeve 482 made of silicone does not cause skin allergies and uncomfortable.
A stopper 484 is formed at one end of the bendable portion 486 to prevent the bendable
portion 486 from separating off the fifth linking part 477. As can be seen from FIG.
7, the bendable portion 486 with the silicone sleeve 482 can move axially relative
to the outlet 442, and as the same function of the bendable portion 463 and the outlet
442.
