JP 2007-253329 A

  However, in the clip structure as described above that uses an elastic member such as a leaf spring, the elastic member is lost and lost, or the elastic member is broken, so that the holding force cannot be obtained, and the function of the clip is impaired. May be. Then, an object of this invention is to provide the clip structure of the writing instrument which can avoid the problem that the elastic member for generating holding force remove | deviates or breaks.

  The clip structure of the present invention is a clip structure of a writing instrument in which a sandwiched object is sandwiched between the clip body and the clip support in a writing instrument including a clip body and a clip support that supports the clip body. The first magnet provided in the clip main body and the second magnet that is provided in the clip support and generates an attractive force between the first magnet and the second magnet are provided.

  According to this clip structure, the holding force for holding the object to be held between the clip main body portion and the clip support body is provided in the first magnet provided in the clip main body portion and the clip support body. It can be generated by the attractive force with the second magnet. Therefore, it is not necessary to provide an elastic member for generating the holding force, and the problem that the elastic member is detached or broken can be avoided.

  The clip body is supported by the clip support and extends in the axial direction of the clip support, and the first magnet is held between the clip body and the clip support when viewed from the portion supported by the clip support. It is good also as being located in the part side which pinches | interposes, and a 2nd magnet facing the 1st magnet.

  According to this configuration, the object to be grasped can be held between the clip main body portion and the clip support body by the attractive force between the first magnet and the second magnet located opposite to each other.

  The clip main body is supported so as to be movable in the axial direction relative to the clip support, and the clip support has a first magnet at a position shifted in the axial direction with respect to the second magnet. Alternatively, a third magnet that generates a repulsive force may be provided.

  According to the configuration of the clip structure described above, the first magnet can be opposed to the second magnet or the third magnet by moving the clip body portion in the axial direction in parallel. . When the first magnet is opposed to the second magnet, a holding force for holding the object to be gripped is generated on the tip end side of the clip main body by the attraction force between the magnets, while the first magnet is moved to the first magnet. When opposed to the magnet 3, the force that pulls the tip of the clip main body away from the clip support is generated by the repulsive force between the magnets. Therefore, the operation of pulling the tip of the clip main body part away from the clip support can be performed relatively easily by the operation of translating the clip main body part in the axial direction from the state where the clip clamping force is generated.

  According to the clip structure of the present invention, it is possible to avoid the problem that the elastic member for generating the holding force is detached or broken.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a writing instrument having a clip structure according to the present invention will be described in detail with reference to the drawings. In the following description, the pen tip side is referred to as “front side” or “tip side”.

  As shown in FIGS. 1 to 4, the writing instrument 1 includes a refill 3 extending in the direction of the axis L, and a synthetic resin shaft cylinder (clip support) 2 that accommodates the refill 3. A base 4 for exposing the front end of the refill 3 is screwed into the front end. A clip portion 10 for locking the writing instrument 1 to, for example, a document, a clipboard, a clothes pocket, or the like is provided at the rear end portion of the shaft tube 2. The clip part 10 includes a clip body part 11 attached along the outer peripheral surface of the shaft tube 2 substantially parallel to the axis L. By holding a pinched object such as a document between the opened front end side of the clip main body 11 and the outer peripheral surface of the shaft tube 2, the locking function of the clip portion 10 is achieved.

  If the writing tool 1 other than the clip main body 11 (the portion consisting of the shaft tube 2, the refill 3, and the base 4) is referred to as the writing tool main body 30, the clip main body 11 is connected to the writing tool main body 30. On the other hand, it is supported movably. As a specific configuration, a base portion 13 for attaching the clip main body portion 11 is formed at the rear end portion of the shaft tube 2 so as to rise from the outer peripheral surface of the shaft tube 2. In the upper end portion of the base portion 13, a long hole 15 that is penetrated in a direction orthogonal to the paper surface of FIG. 2 and long in the front-rear direction is formed. Further, a metal support rod 17 extending in a direction orthogonal to the paper surface of FIG. 2 is attached to a portion near the rear end of the clip main body 11. The support bar 17 has a round bar shape and a length substantially the same as the width of the clip body 11. The support rod 17 has a central portion inserted through the long hole 15 and is fixed to the clip main body portion 11 with both ends supported.

  With this structure, the clip main body 11 can be translated in the front-rear direction (axis L direction) within a movable range corresponding to the length of the long hole 15 with respect to the shaft tube 2, and the support rod 17 is the center of FIG. Can be rotated in a plane parallel to the paper surface. In this case, the rotation range of the clip main body 11 is restricted when the rear end of the clip main body 11 hits the outer peripheral surface of the shaft cylinder 2. Specifically, the maximum opening angle of the clip body 11 with respect to the shaft cylinder 2 is about 10 °. The rotation of the clip main body 11 around the support bar 17 opens and closes the tip of the clip main body 11 for sandwiching documents and the like.

  A magnet (first magnet) 21 is embedded in a portion of the clip main body 11 near the tip, on the side facing the shaft cylinder 2. The magnet 21 is located on the tip side of the portion supported by the base portion 13. Then, two magnets 22 and 23 are arranged and embedded in the front-rear direction on the surface of the shaft cylinder 2 so as to face the magnet 21. Of these, the rear magnet (second magnet) 22 is in a position facing the magnet 21 when the clip main body portion 11 is moved to the rearmost position, and is attached so as to attract the magnet 21. Further, the front magnet (third magnet) 23 is in a position facing the magnet 21 when the clip main body portion 11 is moved forward, and is attached in a direction repelling the magnet 21.

  According to the configuration of the clip portion 10, when the clip main body portion 11 is located at the rearmost position as shown in FIGS. 1 to 3, the tip of the clip main body portion 11 is pivoted by the attractive force between the magnet 21 and the magnet 22. It is attracted in the direction of the cylinder 2, and a pinching force for sandwiching a document or the like between the clip main body 11 and the shaft cylinder 2 is generated. Therefore, if the document or the like is sandwiched between the magnet 21 and the magnet 22 with the clip main body portion 11 moved to the rearmost side, the document or the like is satisfactorily held by the attractive force between the magnet 21 and the magnet 22.

  On the other hand, as shown in FIGS. 5 and 6, when the clip main body 11 is located at the forefront, a repulsive force between the magnet 21 and the magnet 23 generates a force that pulls the tip of the clip main body 11 away from the shaft tube 2. To do. Therefore, if the clip main body 11 is moved to the forefront, the clip main body 11 opens about 10 ° with respect to the shaft cylinder 2 until the rear end of the clip main body 11 hits the outer peripheral surface of the rear end of the shaft cylinder 2. .

  In the clip portion 10, the writing instrument 1 can be locked to a document or the like by the following operation. First, as shown in FIG. 2, the clip portion 10 at the time of writing is in a state in which the clip main body portion 11 is located at the rearmost side and the magnet 21 and the magnet 22 are in close contact with each other by an attractive force. From this state, as shown in FIG. 2, when the rear end 11 a of the clip main body 11 is pushed forward (in the direction of arrow A), the entire clip main body 11 is moved until the support rod 17 hits the front end of the long hole 15. Advance. As a result, the magnet 21 at the tip of the clip main body 11 faces the magnet 23, and a repulsive force between the magnet 21 and the magnet 23 is generated. Due to this repulsive force, the clip body 11 opens about 10 ° with respect to the shaft tube 2 as shown in FIGS.

  With the clip main body 11 opened in this way, as shown in FIG. 5, after inserting the document Y or the like from the front end side between the clip main body 11 and the shaft cylinder 2, the force in the direction of arrow A described above Is released. When the force in the direction of arrow A is released, the clip main body 11 is retracted again by the attractive force of the magnet 21 and the magnet 22, and the magnet 21 and the magnet 22 face each other with the document Y or the like sandwiched therebetween. The document Y sandwiched between the magnet 21 and the magnet 22 is satisfactorily held by the attractive force between the magnet 21 and the magnet 22, and as a result, the writing instrument 1 is satisfactorily applied to the document Y by the clip portion 10. Locked.

  According to the clip structure of the clip portion 10, the holding force for sandwiching the document Y or the like between the clip body portion 11 and the shaft tube 2 is the same as that of the magnet 21 provided on the clip body portion 11 and the shaft tube. 2 can be generated by the attraction force with the magnet 22 provided in 2. Therefore, it is not necessary to provide the clip member 10 with an elastic member for generating a holding force, and the problem that the elastic member is detached or broken can be avoided.

  Moreover, in order to fully exert the holding force, it is preferable to use the magnets 21 and 22 having a strong attraction force. On the other hand, when the clip main body 11 is opened, a strong force against the strong attraction force is used. It becomes necessary, and the operation is troublesome. On the other hand, in the clip portion 10 of the writing instrument 1, a magnet 23 that generates a repulsive force in the magnet 21 is provided in front of the magnet 22. According to this configuration, the clip body 11 can be opened relatively easily by pushing the clip body 11 forward as described above, and the operability when the writing instrument 1 is locked with the clip can be improved. Improvement is achieved.

  In addition, this invention is not limited to the above-mentioned embodiment. For example, the front and rear positions of the magnet 23 attracted to the magnet 21 and the magnet 22 repelling the magnet 21 may be interchanged. In this case, when the clip main body 11 is opened, an operation of translating the clip main body 11 rearward may be performed.

  However, the positional relationship between the magnets 22 and 23 shown in the above embodiment is more preferable from the following viewpoint. In the embodiment, when the clip main body 11 is opened, an operation of pushing the rear end portion 11a of the clip main body 11 forward may be performed in order to translate the clip main body 11 forward. And the operation | movement which pushes the rear-end part 11a of the clip main-body part 11 ahead can be performed by the finger usage similar to operation which knocks a writing tool rear-end part in a normal knock type writing instrument. Accordingly, in this case, the user can lock the writing instrument 1 with a clip by an intuitive operation similar to a knocking operation.

  Furthermore, various positional relationships of the magnets 21, 22, and 23 at the forward limit position of the clip main body 11 can be employed. For example, at the forward limit position of the clip main body 11, a configuration in which about 2/3 of the rear side of the magnet 21 faces the magnet 22 and about 1/3 of the front side of the magnet 21 faces the magnet 23 can also be adopted. . That is, in other words, the positional relationship may be such that the magnets 21 and 23 overlap the magnets 21 and 23. According to this configuration, the magnets 21, 22, and 23 are moved by moving the clip body 11 forward and opening the clip body 11, and then releasing the pushing operation (specifically, by releasing fingers). As a result, the clip body 11 can be automatically moved rearward and the clip body 11 can be closed. In addition, the structure of the fulcrum using the support rod 17 is not limited to this structure, and a known technique such as a protrusion structure that is integrally formed with the clip body 11 by a resin material and protruded is employed. You can also.

  Moreover, in the above-mentioned embodiment, the clip structure of this invention is applied to the clip part 10 comprised in the rear-end part of the writing instrument 1. FIG. In the case of this embodiment, the writing instrument main body 30 of the writing instrument 1 corresponds to a clip support in the clip structure of the present invention. The clip structure of the present invention is not limited to this, and in a cap-type writing instrument that includes a cap that is fitted into the tip of the shaft tube, the clip structure may be applied to a clip portion configured in the cap. In this case, a portion of the cap excluding the clip portion (cap main body portion) corresponds to the clip support in the clip structure of the present invention. Furthermore, in a so-called side knock type multi-core writing instrument, a knock member that is pressed when an arbitrary writing body is selected can be configured as a clip support.
