Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings and embodiments, but the following embodiments are interpretations of the invention, and the invention is not limited to the following embodiments.

1 to 6, the foldable fan pen of this embodiment comprises an outer shaft 1 and a fan surface 2, the outer shaft 1 is cylindrical, and the fan surface 2 is a foldable structure. It is hinged to the distal end of the outer shaft 1 by means of a hinge mechanism 3, and the distal end 11 of the outer shaft 1 is provided with a housing cavity 4 through which the fan surface 2 in the folded state rotates relative to the outer shaft 1. be done.

The fan surface 2 includes an elastic metal wire ring 21 and a cloth 22. An edge cover 23 is sewn on the cloth 22 along the edge of the cloth 22, and a metal wire is formed between the cloth 22 and the edge cover 23. An accommodation space is formed for accommodating the ring 21, and the metal wire ring 21 can be twisted and folded.

In this embodiment, since the metal wire ring 21 is elastically deformable, when the fan surface 2 is fixed to the outer shaft 1, the outer end of the metal wire ring 21 is twisted to change the metal wire ring 21 from the ring shape to "8". At this time, the metal wire ring 21 changes from one ring to two rings, and then the two rings are overlapped while twisting the metal wire ring 21 presenting the "8" shape to complete the folding of the fan surface 2, The folded fan 2 is then rolled into the containment cavity 4 (Fig. 2), the outer shaft 1 serves to limit the redeployment of the fan 2, lowering the center of gravity of the foldable fan pen Not only does it reduce the force required to be applied by the user to grip, allowing the user to use the foldable fan pen for writing for a long time, but also the length of the foldable fan pen is shortened. , convenient to store and carry.

When it is necessary to unfold the fan surface 2, the folded fan surface 2 is first pulled out of the accommodation cavity 4, and the outer shaft 1 releases the expansion restriction of the fan surface 2, so that the fan surface 2 is elastically restored by the metal wire ring 21. In the action of force, it quickly unfolds and returns to its original shape, and at this time, the outer shaft 1 can be used as a handle, so that the foldable fan-type pen can be used as a fan to generate wind.

In this embodiment, when the fan surface 2 is folded and stored in the accommodation cavity 4, the fan surface 2 is fixed so that it does not interfere with the hand when writing with a foldable fan type pen. It is rotated at an angle so that the fan surface 2 is stored in the accommodation cavity 4 (FIG. 3) in a state inclined with respect to the outer shaft 1. - 特許庁At this time, the fan surface 2 in the folded state is inserted only from one side of the accommodation cavity 4 and does not protrude to the other side of the accommodation cavity 4, and then the non-exposed side of the fan surface 2 on the outer shaft 1 is placed at the tip of the hand. Being able to write against it reduces the influence of the fan surface 2 on the user's writing with the foldable fan pen.

Referring to FIG. 1, the bottom surface of the storage cavity 4 is arc-shaped to improve the visual aesthetics of the foldable fan-type pen appearance, so that the user can hold the foldable fan-type pen to write. When doing so, the position facing the bottom surface of the housing cavity 4 on the outer shaft 1 is in contact with the hand, and by providing the arc shape, the bottom surface of the housing cavity 4 and the outer wall surface of the outer shaft 1 are smoothly connected. , the discomfort of the hand when holding and using is reduced.

Referring to FIG. 4, the hinge mechanism 3 includes a rotating member 31 and a pin member 32. The rotating member 31 is rotatable with the pin member 32 fitted therein. Two clamping pieces 33 are provided, and a housing groove 34 for housing the metal wire ring 21 is formed in the rotating member 31. The housing groove 34 communicates with a clearance space 35 between the two clamping pieces 33 and has a cross section of A locking groove 36 having an inverted T shape is formed, and the pin member 32 is detachably attached to the outer shaft 1 .

Both the end surface of the distal end 11 of the outer shaft 1 and the side surface of the rotating member 31 are arc-shaped (FIGS. 1 and 4). The end surface of the terminal 11 of 1 has a spherical shape in accordance with the side surface of the rotating member 31 to improve the safety of using the foldable fan type pen when writing with the foldable fan type pen.

Referring to FIG. 4, the outer wall surface at the position corresponding to the rotating member 21 on the distal end 11 of the outer shaft 1 is recessed to form a planar pressing surface 8 . Since the rotating member 31 and the outer shaft 1 can rotate freely, when the fan surface 2 is unfolded and used, in order to ensure the effect of fanning with a foldable fan type pen, the outer shaft 1 A position corresponding to the housing cavity 4 is pressed, and the rotating member 31 is sandwiched by the outer shaft 1. - 特許庁

When the user's fingers are pressed against the two pressing surfaces 8, the force applied by the fingers directly acts on the outer shaft 1 and the rotating member 31, so that the holding strength of the outer shaft 1 against the rotating member 31 is greatly improved. , the stability of the relative position between the fan surface 2 and the outer shaft 1 can be further improved, and the foldable fan-type pen can ensure the effect of fanning and creating wind.

At the same time, the function of fanning the foldable fan-type pen to create wind is mainly used when the temperature is high, and by providing the pressing surface 8 in a flat shape, the effect of finger perspiration on the pressing operation is reduced. can do.

5 and 6, a mouthpiece 5 is rotatably inserted into the tip of the outer shaft 1, and a lead feeding mechanism 6 is provided between the outer shaft 1 and the mouthpiece 5. The lead feeding mechanism 6 is , a pen core 61 and a slider 62. The pen core 61 is inserted from bottom to top and is fixed to the slider 62. The top of the slider 62 is slidably mounted on the outer shaft 1 so as not to rotate. A protrusion 63 is provided on the inner wall surface of the mouthpiece 5 into which the core 61 is fitted, and a sliding groove is obliquely drilled in the outer wall surface of the bottom of the slider 62 along the circumferential direction so that the protrusion 63 can slide. .

In this embodiment, the outer wall surface of the mouthpiece 5 is provided with a convex ring portion 71 , and the inner wall surface of the outer shaft 1 is provided with a groove 72 that fits the convex ring portion 71 . A rotatable arrangement between the base 5 and the outer shaft 1 is achieved by fitting the groove 72 . When the cap 5 rotates with respect to the outer shaft 1 , the protrusion 63 slides in the obliquely arranged sliding groove 64 , and the slider 62 slides with respect to the outer shaft 1 , thereby moving the pen core 61 . By moving, the pen tip of the pen core 61 on the outer shaft 1 is expanded and contracted (FIGS. 5 and 6).

The protrusions 63 can be fixed to both ends of the sliding groove 64 through a buckle structure, thereby improving the stability of the expansion and contraction state of the pen tip of the pen core 61 on the outer shaft 1, and folding the fan type. to ensure the writing effect of the pen.

The foregoing description of this specification is intended to be exemplary of the invention only, and those skilled in the art may make various modifications, supplements, or similar modifications to the specific embodiments described. can be used to replace them, and fall within the protection scope of the present invention without departing from the scope specified in the description of the present invention or the claims of the utility model registration.
