Description

  The present invention relates to an assembly chopstick.

  Conventionally, as shown in FIG. 6 and FIG. 7, there is known an assembly chopstick 3 having a gripping portion 1 and a food clamping portion 2, which are assembled as shown in FIG. 6 and separable as shown in FIG. It has been.

  According to the assembled chopstick 3, the two assembled chopsticks 3 are used as a whole in the assembled state shown in FIG. 6, and after use, the gripping portion 1 and the food sandwiching portion 2 are separated as shown in FIG. It is stored in a storage container.

nothing special

  The assembly chopsticks 3 of the prior art has a gripping part 1 and a food sandwiching part as shown in FIG. 6 by a saddle between a fitting projection 4 formed integrally with the food sandwiching part 2 and a fitting hole 5 formed in the gripping part 1. 2 is integrally assembled and released, and the gripping portion 1 and the food holding portion 2 are separated as shown in FIG. . Therefore, the assembled state of the gripping portion 1 and the food sandwiching portion 2 is maintained by the frictional force generated by the eye contact between the fitting protrusion 4 and the fitting hole 5, and the fitting protrusion 4 and the fitting hole are resisted against the frictional force. The state in which the grip portion 1 and the food sandwiching portion 2 are separated can be obtained by pulling 5 apart in the axial direction. There is also an assembly chopstick 3 in which a fitting hole is formed in the grip portion 1 and a fitting protrusion is formed in the food sandwiching portion 2.

  By the way, the assembly chopsticks 3 are often made of wood or bamboo, followed by assembly chopsticks 3 made of synthetic resin or metal. However, wood and bamboo are inferior in wear resistance. In the case of an assembled chopstick 3 made of wood or bamboo that is inferior in wear resistance, the coupling protrusions 4 and the fitting holes 5 are worn in a short time by repeating the coupling and separation, and the frictional force of the eyelashes is reduced. . For this reason, it becomes impossible to hold the proper eyelashes due to both 4 and 5, for example, when the food is sandwiched, the food sandwiching portion 2 falls off from the gripping portion 1 and becomes unusable, or the gripping portion 1 and the food sandwiching portion 2 As a result, relative rotation around the axis occurs, and the usability of the assembly chopsticks 3 is reduced.

  On the other hand, the assembly chopsticks 3 made of synthetic resin or metal have better wear resistance than the assembly chopsticks 3 made of wood or bamboo. Therefore, since the wear of the fitting protrusion 4 and the fitting hole 5 can be suppressed, the drop of the food pinching portion 2 from the gripping portion 1 is normally suppressed by suppressing the reduction in the frictional force of the eye eye over a long period of about 1 to 2 years. And inconvenience such as a decrease in usability due to relative rotation around the axis can be avoided. However, even if the frictional force of the eyelashes decreases due to the wear of the fitting protrusions 4 and the fitting holes 5 over time, it does not have a function to compensate for this, so long-term use exceeding about two years is expected. Can not.

  That is, in the assembly chopsticks 3 of the prior art described with reference to FIGS. 6 and 7, if the grip portion 1 and the food sandwiching portion 2 are made of a popular material such as wood or bamboo, the useful life is short and not practical. Further, if the gripping portion 1 and the food sandwiching portion 2 are made of synthetic resin or metal, although the service life is extended as compared with the assembly chopsticks 3 composed of the gripping portion 1 and the food sandwiching portion 2 made of wood or bamboo, the life span is reduced. Long-term use exceeding 2 years cannot be expected.

  The present invention has been made in order to solve such problems. Regardless of the constituent material of the gripping part and the food sandwiching part, the frictional force reduction of the hameai is suppressed for a long period of time. It is possible to prevent the food gripping part from dropping off, and to reduce the usability due to relative rotation around the axis of the gripping part and the food gripping part. Thus, an object is to provide an assembly chopstick that can extend the service life.

  An assembled chopstick according to the present invention has a gripping portion and a food sandwiching portion, and these are assembled detachable chopsticks, and the gripping portion and the food sandwiching portion can be separated through a coupling means. It is characterized by being coupled to each other.

  According to this, two assembly chopsticks can be used as one glance by assembling the gripping part and the food sandwiching part with each other via the coupling means. After use, the gripping part and the food sandwiching part can be separated by separating the coupling means and then stored in a storage container as appropriate. In addition, by configuring the coupling means with a material with excellent wear resistance, it is possible to hold the food from the gripping portion by suppressing the decrease in the frictional force of the eyelash for a long time regardless of the constituent material of the gripping portion and the food gripping portion. It is possible to prevent the occurrence of inconveniences such as part dropout and usability drop. Therefore, it is possible to extend the useful life of the assembled chopsticks in which the gripping portion and the food holding portion are made of wood or bamboo, which are popular materials.

  Further, the coupling means includes one bonded body fixed to the distal end portion of the gripping portion and the other bonded body fixed to the proximal end portion of the food sandwiching portion. And the food sandwiching portion are coupled to each other, and the gripping portion and the food sandwiching portion are separated by releasing the hameai.

  According to this, one combined body and the other combined body can be manufactured with high accuracy by metal machining. Therefore, it is possible to maintain the combined state of the two combined bodies by the frictional force set to a suitable value, and to release the combined eyes of both the combined bodies by a small separation force, so that the grip portion and the food holding portion can be easily Can be separated.

  Further, at least one of the one combined body and the other combined body is made of a magnetic metal material, and at least the remaining one combined body is provided with a permanent magnet. According to this, even if the frictional force of the eye eye is reduced due to aged wear of one joint and the other joint by continuous use over a long period of time exceeding about two years, the magnetic metal material of the permanent magnet is reduced. The adsorption action compensates for the reduction in the frictional force of the eye and suppresses the spontaneous separation between the gripping part and the food sandwiching part, thereby extending the useful life of the assembled chopsticks.

  Further, a relative rotation preventing means is provided for both the combined body of the one combined body and the other combined body, and the gripping portion and the food sandwiching section are provided by the relative rotation preventing means combined when the both combined bodies are engaged. The relative rotation about the axis at the time of assembling is prevented. According to this, even if the frictional force of the eyelashes is reduced due to aged wear of one of the bonded bodies and the other bonded body due to continuous use over a long period of time exceeding about 2 years, the relative rotation preventing means prevents Compensating for a decrease in frictional force prevents relative rotation around the axis between the gripping part and the food sandwiching part, preventing usability from decreasing and extending the useful life of the assembled chopsticks.

  Furthermore, the gripping part and the food holding part are made of wood and bamboo. It is characterized by comprising a single structure made of synthetic resin or metal or a composite structure thereof. According to this, it is possible to extend the service life with a single structure assembled chopsticks. In addition, with the composite chopsticks with a composite structure, the service life can be extended, and the user can enjoy the visual feeling created by combining different materials.

  According to the present invention, regardless of the constituent materials of the gripping part and the food sandwiching part, the food gripping part falls off from the gripping part, or the gripping part and the food sandwiching part are suppressed for a long period of time by suppressing the reduction of the frictional force of the eye eye. It is possible to prevent a decrease in usability due to relative rotation around the axis and compensate for this even if the frictional force of the eyelashes decreases due to aging deterioration, and a substantial extension of the service life can be realized. .

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is an exploded perspective view of FIG. 1, FIG. 3 is an enlarged cross-sectional view showing a coupling state of one embodiment of the coupling means, and FIG. FIG. 5 is an enlarged cross-sectional view showing the fixation of the other combined body to the food sandwiching portion. 1 to 5, the assembled chopstick 20 has a wooden gripping portion 21 and a wooden food sandwiching portion 22, which are detachably coupled to each other via a coupling means 23.

  The grip portion 21 has a circular cross section with a substantially uniform outer diameter from the base end portion 21a to the tip end portion 21b, and a coupling means fixing hole 24 is formed in the tip end portion 21b. Moreover, the food clamping part 22 is a taper-shaped thing gradually diameter-reduced from the base end part 22a to the front-end | tip part 22b, and the coupling means adhering hole 25 is formed in the base end part 22a.

  The coupling means 23 is made of an rustless metal, and one coupling body 230 that is secured to the coupling means securing hole 24 of the gripping part 21 and the other coupling body 231 that is secured to the coupling means securing hole 25 of the food sandwiching section 22. Is provided. Since the coupling means 23 is made of a non-rust metal, it is possible to avoid the occurrence of inconveniences that cannot be coupled and cannot be separated due to rust.

  One coupling body 230 is a sleeve-shaped member made of a copper alloy (brass), and has a main body portion 230a having a uniform hail eye inner diameter d1 and a flange portion that projects outside the diameter provided at the tip of the main body portion 230a. 230b, the permanent magnet 26 is built into the rear end of the main body 230a by caulking, and the flange 230b has a pair of locking projections 230c at equal intervals in the circumferential direction. The main body 230a, which is formed to protrude slightly forward from the front end surface and is inserted into the coupling means fixing hole 24 of the grip portion 21, is bonded to the coupling means fixing hole 24 with an adhesive (not shown). The fixed body 230 is fixed to the distal end portion 21b of the grip portion 21, and the flange portion 230b protrudes in front of the distal end portion 21b.

  The other coupling body 231 is made of a metal having a magnetizing characteristic, and has a flange portion 231a provided at a substantially central portion in the axial direction, and a circular cross section continuously provided on one side of the flange portion 231a and a uniform outer diameter. The fixing part 231b and the flange part 231a are connected to the other side of the flange part 231a and have a circular cross section and a uniform outer diameter part 231c. The outer diameter of the flange part 231a is the same as the outer diameter of the flange part 230b of the one coupling body 230. A pair of locking holes 231d that are set equally and can be engaged with and disengaged from the pair of locking protrusions 230c are formed at equal intervals in the circumferential direction, and the pair of locking protrusions 230c and the pair of locking holes 231d constitutes a relative rotation preventing means 27. And the other coupling body 231 is the base end of the food clamping part 22 by adhere | attaching the fixing | fixed part 231b inserted in the coupling | bonding means fixing hole 25 of the food clamping part 22 to the coupling | bonding means fixing hole 25 with the adhesive agent which is not shown in figure. The flange portion 231a and the eye-eye portion 231c protrude behind the base end portion 22a by being fixed to the portion 22a.

  The saddle eye inner diameter d1 of the main body 230a in one joined body 230 and the saddle eye outer diameter d2 of the saddle eye portion 231c in the other joined body 231 are determined by the mutual contact force between the joined bodies 230 and 231 and the gripping portion. 21 and the food sandwiching portion 22 can be held in a coupled state (see FIGS. 1 and 3), and the gripping portion 21 and the food sandwiching portion can be released by releasing the coupling of the combined bodies 230 and 231 with a small separation force. 22 is set with high accuracy by machining so that it can be easily separated (see FIGS. 2, 4 and 5).

  According to the assembled chopsticks 20 having the above-described structure, the two assembled chopsticks 20 are used as a whole by assembling the gripping portion 21 and the food sandwiching portion 22 together as shown in FIG. it can. After use, the gripping portion 21 and the food sandwiching portion 22 are separated as shown in FIG. 2 by separating the combined bodies 230 and 231 by releasing the binding eye 23 in the coupling means 23, and then appropriately stored in a storage container (not shown). Can do. Here, the dimension L in the axial direction from the proximal end portion 21a of the gripping portion 21 to the flange portion 230b of one combined body 230 and the distal end portion 22b of the food sandwiching portion 22 to the distal end of the saddle eye portion 231c of the other combined body 231. By setting the dimension L1 in the axial direction to a substantially equal value, the swinging of the gripping part 21 and the food sandwiching part 22 in the storage container in the axial direction can be suppressed, and the stability of the storage state can be improved. .

  Since one coupling body 230 in the coupling means 23 is composed of a copper alloy having excellent wear resistance, and the other coupling body 231 is composed of a metal having excellent wear resistance, the grip portion 21 and the food sandwiching portion 22 are configured. Even in the case of a wooden having poor wear resistance as in the present embodiment, the gripping portion 21 when the assembled chopstick 20 is used can be suppressed for a long period of time by reducing the frictional force reduction of the main body portion 230a and the eye portion 231c. Therefore, it is possible to prevent the food sandwiching portion 22 from dropping off naturally. That is, even with the assembled chopsticks 20 in which the gripping portion 21 and the food sandwiching portion 22 are made of wood, which is a popular material, the useful life of the chopsticks 20 can be extended. This also applies to the assembly chopsticks 20 in which the grip portion 21 and the food sandwiching portion 22 are made of bamboo.

  One combined body 230 and the other combined body 231 can be easily manufactured with high accuracy by machining. Therefore, the combined state of both the combined bodies 230 and 231 can be maintained by the Saddle eye frictional force set to a suitable value, and the combined state of both the combined bodies 230 and 231 can be released by the small separating force to And the food sandwiching portion 22 can be easily separated.

  Normally, long-term continuous use exceeding about two years causes wear over time on the inner peripheral surface of the main body 230a in one of the bonded bodies 230 and the outer peripheral surface of the hail eye 231c in the other bonded body 231. Even if the frictional force of the magnet is reduced, the attracting action of the saddle eye portion 231c by the magnetic force of the permanent magnet 26 compensates for the frictional force reduction of the saddle eye and suppresses spontaneous separation of the grip portion 21 and the food sandwiching portion 22; The service life of the assembled chopsticks 20 can be extended.

  Further, normally, long-term continuous use exceeding about two years causes wear over time on the inner peripheral surface of the main body portion 230a in one combined body 230 and the outer peripheral surface of the eyepiece portion 231c in the other combined body 231. Even if the frictional force of the eyelashes is reduced, the engagement of the pair of locking projections 230c and the pair of locking holes 231d constituting the relative rotation preventing means 27 is obtained, whereby the friction of the eyelashes is obtained. It is possible to compensate for the force reduction and prevent relative rotation around the axis when the gripping portion 21 and the food sandwiching portion 22 are assembled and used, thereby preventing usability from being lowered and extending the useful life of the assembly chopsticks 20.

  According to the present invention, even with the assembled chopsticks 20 in which the gripping part 21 and the food sandwiching part 22 are made of synthetic resin or metal, the attracting action of the eye part 231c by the magnetic force of the permanent magnet 26 and the relative rotation preventing means 27 6 and 7 can be used in combination so that the gripping portion 1 and the food sandwiching portion 2 in FIGS. 6 and 7 have a longer service life than the conventional assembly chopsticks 3 made of synthetic resin or metal. Can be extended.

  As described above, the gripping portion 21 and the food sandwiching portion 22 of the assembly chopsticks 20 are made of wood or bamboo. Whether it is made of synthetic resin or metal, the service life can be extended. Also, the gripping part 21 and the food sandwiching part 22 are made of wood and bamboo. Even if it is composed of synthetic resin or metal, the service life can be extended and the visual feeling produced by the combination of different materials can be enjoyed.

  In the above-described embodiment, the permanent magnet 26 is built in one sleeve-like coupling body 230 made of a copper alloy (brass), and the other coupling body is made of a metal having a magnetization characteristic by the permanent magnet 26. Although the configuration in which 231 is adsorbed is described, a configuration in which one coupling body 230 is manufactured in a sleeve shape with metal and the permanent magnet 26 is incorporated may be used. Moreover, although the assembly chopsticks 20 having the grip portion 21 and the food sandwiching portion 22 having a circular cross section are described, the cross-sectional shapes of the grip portion 21 and the food sandwiching portion 22 are oval, elliptical, or polygonal.
