Abstract

PROBLEM TO BE SOLVED: To provide chopsticks which are excellent in balance, easy to grip, smoothly operated with small force, hardly roll off a plate or a table, can achieve unique external design and ornamental expression, and can be sanitarily held by making a part contacting the mouth afloat, and provide a holding tool for the same.SOLUTION: By inserting a weight material 5 from a rear part 4 of a chopstick 1, an operation fulcrum at the time when the chopstick is put on the hand becomes closer to a centroid point 1b after eccentricity to make the balance of the chopstick good and thereby the operation thereof can be smoothly performed. The chopstick achieves unique external design and ornamental expression at all time by being eccentric to a centroid point 5b with low centroid closer to the lower side from a centroid point 5a that the chopstick originally has. Moreover, the chopstick can be attached to a chopstick rest with a magnet or the like in the state in which a part 11 contacting the mouth is made afloat. Consequently, the chopsticks which can be sanitarily held and stored and a holding tool for the same can be configured as a set.

Description

  The present invention relates to a chopstick that is well-balanced and can be operated smoothly, and that is able to achieve a unique design and decorative expression by standing still in a certain direction even when it is rolled, and for that purpose insertion arrangement The present invention relates to a chopstick that can be held hygienically by floating a portion to be a mouth in the air by making a weight material to be magnetic, and a tool for holding the chopstick.

  Chopsticks are mature products that have been used for many years by people in Asia as eating tools, but with the recent development of resin molding technology, it is possible to manufacture chopsticks with complex shapes, and chopsticks that do not roll Although the proposal of the shape (see Patent Documents 1 and 2) is described, it is a proposal only for the outer shape of a combination such as a non-cylindrical square or polygon, and in particular, a notable function for stopping rolling other than that Was not included.

Some chopsticks (see Patent Document 3) that are easy to hold and have a good balance by placing a rubber cap at the rear end (see Patent Document 3) cannot be denied, but they are superior in design and cleaning. There seems to be no.

In addition, there are chopsticks that are easy to clean by standing in the water by attaching a weight to the rear (see Patent Document 4), but most resin and metal chopsticks other than wood have a higher specific gravity than water Since they do not float, in order to float upright, it is necessary to form a hollow structure inside them, and there is a concern that a high level of technical skill is required for their production, which would be expensive. In addition, it is considered that a desired result can be obtained by adjusting the hollow capacity and position without intentionally arranging a weight.

Other than chopsticks, there is a writing instrument with a structure that makes it difficult to roll by inserting a weight (see Patent Document 5), but it has only the eccentricity of the center of gravity while still in a cylindrical shape, so there was also the inconvenience that it did not stop easily if it started rolling.

  In addition, chopsticks are important enough to be revered as a “sacred instrument” used by God for sacred things, and “Longevity Chopsticks” is not a tool for eating, but a tool for healthy and long life. At the landlord shrine, “Longevity Chopsticks” were awarded with the wish for good health and longevity. In addition, many shrines are now treated as good luck charms and lucky charms with letters such as “household safety” and “business prosperity”.

Japanese Patent Laid-Open No. 10-328209 (FIG. 1) JP 2010-104528 A (FIG. 1) Registered Utility Model No. 3181048 (Figure 1-5) JP 2012-161393 A (page 2-3, FIG. 1-2) JP 2012-166504 A (page 2-3, FIG. 1-4)

  The present invention has been made in view of the above-mentioned shortcomings of conventional chopsticks, and as its first object, by realizing a chopstick that is easier to hold and operate. There is.

  The second purpose is to prevent the chopsticks from rolling down on the bowl or table as much as possible, and to stand still in a certain direction even when rolling, the design and decoration can be uniquely appealed. It is to realize chopsticks.

  The third purpose is to use a magnetic detachment function to keep the part of the chopstick mouth clean, especially when the chopstick and chopstick rest, chopstick box, chopstick stand, etc. are floating in the air. It is to realize a combined hygienic holding and storage configuration.

  Means employed by the present inventor for solving the above technical problem will be described with reference to the accompanying drawings.

  In order to improve the balance between the front part 2 and the rear part 4 of the chopsticks so that the operation can be performed smoothly, the weight material 5 is inserted from the rear part 4 of the chopsticks 1, and the original center of gravity of the chopsticks 1 is moved backward from 1a. By decentering to 1b closer to the part 4, the operation fulcrum when the chopsticks are picked up is set near the center of gravity 1b after decentering.

Also, in order to prevent the chopsticks 1 from rolling over the table or table, it is eccentric from the original center of gravity 5a to the lower center of gravity 5b, and the back surface outline 6 (kamaboko-shaped) ), That is, the ground plane with the top cylindrical part 1x and the bottom plane part 1y combined, the bottom plane part 1y is always in contact with the horizontal floor surface, that is, the top cylindrical part 1x is The chopsticks are designed to be stationary and always have a unique design and decorative appearance.

Furthermore, in order to make it possible to easily and hygienically hold the portion 11 entering the mouth in a suspended state, the weight material 5 arranged for eccentricity of the chopsticks is made of a magnetic material, and a magnet 8 is partly provided. It is adopted that a holder such as a chopstick rest 7 is also configured.

  Furthermore, when the chopsticks 1 are directly placed on the floor or wall surface or rolled, the upper cylindrical part 1x or the bottom flat part 1y of the part that touches the chopsticks 1 is clean without touching those surfaces. In order to maintain this, the contour means of forming the refracting line 3 instead of aligning the contour lines of the part 11 entering the mouth and the handle part 12 is also employed.

  In the present invention, when the chopstick is placed in the hand, that is, when the chopstick is placed between the base of the thumb and the index finger, the center of gravity 1b of the chopstick 1 is in the vicinity thereof, and the balance is good and the operation is performed. It is possible to provide a comfortable eating tool with minimal force.

  Furthermore, by configuring the outer shape of the kamaboko shape and the eccentricity of the center of gravity inside, it is possible to more strongly realize a rolling prevention function that makes it difficult for chopsticks to roll off from a table or table.

  In addition, the chopsticks that can always have a unique design / decorative appearance can be provided by a structure that is stationary in a certain direction.

  Further, according to the present invention, if necessary, the weight member 5 is made of a magnetic material and used in combination with a holder provided with a magnet that can be easily detached, so that the portion 11 entering the mouth can be suspended. It can be kept and stored while keeping it clean and floating.

  Furthermore, only the portion 11 entering the mouth is formed by being refracted thinly from the refraction line 3 toward the front portion 2, so that even when the chopsticks 1 are installed on the floor or wall surface, they enter the mouth. Since the portion 11 is not touched, it can be placed in a sanitary manner, thereby preventing infection of bacteria and pathogens in the mouth, and is particularly useful for preventing nosocomial infections in public facilities such as hospitals.

  This chopstick that always stops with the top cylindrical part 1x facing upward even if it rolls up like a rising spill, can be seen as a positive movement, so it can be used as an auspicious item handled at shrines, etc. Even when positive characters such as “Rebirth” are entered, or when the name of a company or store is entered, it can be expected to have a positive impression and a sense of image enhancement, that is, the industrial utility value as an appealing tool. The

It is a side view showing the chopsticks of 1st Embodiment of this invention. It is a top view showing the chopsticks of 1st Embodiment of this invention. It is a rear view showing the chopsticks of 1st Embodiment of this invention. It is a side image figure showing the chopsticks of 1st Embodiment of this invention. It is a side image figure showing the chopstick rest of 1st Embodiment of this invention.

  The mode for carrying out the present invention will be described in more detail with reference to the drawings specifically illustrated as follows.

  A first embodiment of the present invention will be described with reference to FIGS. In the figure, reference numeral 1 denotes a chopstick body, reference numeral 2 denotes a front part of the chopstick tip, and reference numeral 4 denotes a rear part. A part 11 entering the front mouth and a handle part 12 other than that. The refraction line at the boundary is denoted by reference numeral 3.

  First of all, the decorative recess 13 that is a feature of the outer shape is formed by cutting off a part of the upper cylindrical part 1x, and when it is basically held, it is fixed with the thumb just between this part of the chopsticks In other words, the flat surface of the decorative recess 13 is opposed to the bottom flat surface 1y. That is, since both planes are sandwiched, this embodiment adopts a shape that can be sandwiched more stably. (See Figure 1)

In the present embodiment, the material of the chopstick body 1 is made of a heat-resistant resin PBT, and the one that is injection-molded by a mold and that has a urethane resin coating on the surface is adopted.

  Further, in the present embodiment, the handle portion 12 is subjected to a masking process, and only the portion 11 to be put in the mouth is separately subjected to a non-slip process in which irregularities are formed by resin coating. (See Figure 4)

  In constructing the eccentricity of the center of gravity of the present embodiment, the weight material 5 is directly inserted from the rear portion 4 side simultaneously with the injection molding or the dummy material is once inserted to open only the elongated hole and then the weight material 5 is inserted. It was arranged inside by the procedure. Moreover, after insertion, the same material resin shall be welded and sealed in the insertion port. (See FIGS. 1, 2, and 4).

  At this time, a chopstick that can be easily attached to and detached from the magnet 8 is realized by inserting a magnetic material such as iron into the weight member 5 as necessary. In this embodiment, a round bar-shaped iron core having a diameter of 2.7 mm and a length of 100 mm is inserted. (See FIGS. 4 and 5).

  With this configuration, even magnetic materials that are concerned about rust do not appear on the surface in normal use, and the surface hardness can be kept soft, so that many times of washing and long-term use Can be provided with high durability. (See Figure 4)

  At the same time, a chopstick rest 7 with a magnet 8 is constructed so that the chopstick 1 having a magnetic body can be easily detached and held. (See Figure 5)

In addition, a similar chopstick box or chopstick stand that can be held hygienically without touching the portion 11 entering the mouth by floating in the air by arranging a similar magnet 8 can be considered.

  In addition, for use as a positive product, it may be possible to provide chopsticks with name processing such as company names and messages, or to prepare chopsticks of various colors that have the meaning of Feng Shui. .

  Similarly, since the product of the present invention is also a positive movement, for example, by adding characters such as “household safety” and “business prosperity”, the utility value of the shrine or the like treated as a good luck charm or a souvenir is further increased. It seems.

  In addition, because of the movement of getting up all the time, for example, if the market value is recognized as a gift for parents in hospitals and nursing homes, the price can be set high. It is also possible to use genuine chopsticks with genuine lacquering.

  The product of the present invention has a good balance of chopsticks and is easy to operate even for those with weak chopsticks. In that sense, it is also considered highly valuable as a gift for the elderly.

  It also has a structure that is difficult to roll down, so it seems to be useful as an auspicious item in prayers for passing exams such as “study achievement”.

  However, the main body material of the chopstick body 1 and the weight material, the surface treatment (including the case where no surface treatment is performed) material and color, the shape of the decorative recess 13 and the shape of the refracting line 3, etc. None of these, such as letters in the name, limit the scope of the present invention.
