Description

  The present invention relates to a knock-type pen, and more specifically, a knock-type of a type in which a core of a desired color is projected and retracted from a tip of a shaft cylinder by operating a knock whose part (finger hook portion) protrudes from the upper portion of the shaft cylinder. It is about a pen.

  Knock pens of the above type (for example, black and red two-color ballpoint pens) are widely available in various designs. The pair of knocks there is assembled to the upper part of the knock body that is normally urged upward by a push-up spring with a core fitted to the lower end and wound around the upper part of the core.

  In the knock pen of the above mechanism, the applicant of the present application first enlarges the finger hooks of the pair of knocks so that they look like the ears of animals or characters, frog eyes, etc. It has been well received in the market by planning products with a design like this. The product employs an assembly structure in which the knock does not drop off from the knock body even when a diagonally outward force is applied to the finger hook during the pressing operation (Patent Document 1: Japanese Patent No. 5064320). Patent Document 2: Japanese Patent No. 5802365).

  In the case of the above-mentioned knock type pen, the pair of knocks are enlarged and looked at the ears of animals, characters, etc., the eyes of frogs, etc., but the pair of knocks is simply a side. The surface that protrudes in the direction is flat, and the pair of knocks are separated into left and right, and there is a limit to the pursuit of fun and taste.

There is an effect that is further promoted.

1 is an overall external view of one embodiment of a knock pen according to the present invention (when one knock is pressed); FIG. It is a perspective view of the important section of one embodiment of a knock type pen concerning the present invention. It is a disassembled perspective view of the principal part of one Embodiment of the knock type pen which concerns on this invention.

  A mode for carrying out the present invention will be described with reference to the accompanying drawings. The illustrated knock type pen according to the present invention is of a type in which one of the two cores 2 of different colors is selected to be projected and retracted. The two types of cores 2 that protrude from the tip of the shaft cylinder 1 and a pair of knocks 3 and 3a that perform the operation of feeding the core 2 are configured.

  Each of the knocks 3 and 3a has a knock main body 4 fitted with a core 2 at the lower end and constantly urged upward by the action of a spring 6, and a knock body 4 assembled to the knock main body 4 so as to be three-dimensionally larger from the shaft cylinder 1 during assembly. It consists of finger-hanging portions 7 and 7a that protrude. The finger hook part in the conventional knock type pen is merely a flat plate projecting to the side, but the finger hook parts 7 and 7a in the present invention are half of the front surface from the side surface of the shaft tube 1. It has a large and three-dimensional shape that can be covered over.

  The finger hooks 7, 7 a are configured by three parts, that is, a locking member 8 assembled to the knock body 4, a front surface constituent member 9, and a back surface constituent member 10. It is integrated on the other side. For this purpose, for example, two receiving cylinders 11 are formed on the inner surface of the front surface constituting member 9, and an insertion rod 12 corresponding to the receiving cylinder 11 is provided on the inner surface of the rear surface constituting member 10. Further, the locking member 8 is provided with an insertion hole 13 for allowing the insertion rod 12 to pass therethrough. Contrary to the above, the insertion rod 12 may protrude from the inner surface of the surface constituting member 9 and the receiving cylinder 11 corresponding to the insertion rod 12 may be provided on the inner surface of the rear surface constituting member 10.

  The finger hooks 7, 7 a composed of these three parts are configured such that the insertion rod 12 of the back surface component 10 is inserted into the insertion hole 13 of the locking member 8 and the tip thereof is inserted into the receiving cylinder 11 of the surface component 9. Formed by. In the assembled state, one half of one three-dimensional shape is formed.

  In the illustrated example, one finger hook 7 constitutes one half of a three-dimensional ribbon, the other finger hook 7 a constitutes the other half, and the finger hook 7 in the state where the core 2 is retracted. A three-dimensional ribbon is formed by the finger-hook portion 7a. In FIG. 1, a state where one knock 3 is pressed is indicated by a solid line, and in this state, one half of the ribbon and the other half are shifted. The front surface component member 9 and the back surface component member 10 can have other arbitrary shapes. For example, a three-dimensional shape such as an animal or a character's face can be created.

  The locking member 8 includes a substrate 14 in which the insertion hole 13 is formed, and a locking portion 15 that is formed at one end of the substrate 14 and is engaged in an engagement opening 20 provided in the knock body 4. The The locking portion 15 is generally elastic to some extent in the up-down direction when its center is bent into a V-shaped cross section. In addition, an upper hooking portion 16 protruding upward is formed at the upper surface edge of the locking portion 15, and a lower hooking portion 17 protruding downward is formed at the lower surface edge of the locking portion 15. A protrusion 18 is provided so as to be inserted into the formed support hole.

  The pair of knocks 3, 3 a having such a configuration is incorporated in the shaft cylinder 1 in the same manner as the conventional one with the core 2, and in that state, the knock body 4 is formed on the upper portion of the shaft cylinder 1. It moves up and down along the slit and is locked at the descending end. Since the mechanism for extending and retracting the core 2 by pushing down the knocks 3 and 3a and the locking mechanism for the knocks 3 and 3a are not different from ordinary ones, detailed description thereof is omitted.

  In one embodiment, a design or a character is expressed at the upper part of the shaft cylinder 1 so as to appear when one of the knocks 3 and 3a is pressed. In that case, it is preferable that the symbol or character that appears is related to the form of one or both of the knocks 3, 3a or the meaning expressed therefrom. For example, when a tiger is represented by the knocks 3 and 3a, a character of Tiger is written.

  The knock-type pen according to the present invention is as described above, and the pair of finger hooks 7 and 7a can express the face of an animal or a character or other three-dimensional shapes, not only for writing purposes. It is accepted as a kind of fun goods with rich taste and variety, and its industrial applicability is great.
