Abstract

(57) [Summary] [Purpose] The elastic cylinder for preventing slippage does not move during writing work, and therefore writing work can be performed smoothly. [Structure] A ridge edge 7 and a recessed edge 8 along the axial direction of the body 1 are provided on an outer peripheral surface 2'of a finger rest portion 2 of a writing instrument body 1, and these ridge edge 7 and the recessed edge 8 are engaged with each other. The elastic cylinder 4 having the recessed edge 9 and the projecting edge 10 provided on the inner peripheral surface 4 ′ is fitted into the finger rest 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a non-slip device for writing instruments such as ballpoint pens and mechanical pencils.

[0002]

[Prior art]

 The tip of the writing instrument such as a ballpoint pen is provided with unevenness so that the writing instrument can be easily held.However, if the writing effect is uneven, the pressure during writing will inevitably be applied to the fingertips, causing pain. I may feel. For this reason, it has become popular in recent years to dispose a rubber elastic body on the finger holding portion, but the work of attaching the elastic body to the finger holding portion is rather complicated, and in order to avoid the complexity. A means is employed in which the elastic body is formed into a tubular shape and the finger rest of the writing instrument body is fitted into the tubular body.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional example, the elastic tubular body is simply fitted into the finger rest, but the fitted state cannot be maintained due to the change with time of the elastic tubular body and the elastic tubular body moves (mainly moves). As a result, it rotated around the main body), which made it originally convenient for writing work, but on the contrary it caused inconvenience in writing work.

The present invention has been devised in view of such a normal situation.

[0005]

[Means for Solving the Problems]

 At the tip of the writing instrument main body, there is a protruding edge or a concave edge on the outer peripheral surface, and on the inner peripheral surface of an elastic cylinder made of an elastic material such as rubber, a concave edge or a protruding edge, at least each axis line. A part which is provided along the direction, and the recessed edge or protruding edge of the finger rest is engaged with the protruding edge or recessed edge of the elastic tubular body to insert the finger rest into the elastic tubular body. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of a non-slip device for a writing instrument according to the present invention, FIGS. 1 to 3 show a first embodiment, FIGS. 4 to 6 show a second embodiment, and FIG. FIG. 2 is a sectional view taken along line bb of FIG. 1, FIG. 2 is a sectional view taken along line bb of FIG. 4, FIG. 4 is a partially cutaway front view, and FIG. 4 is a sectional view taken along line cc of FIG. 4, and FIG. 6 is a sectional view taken along line dd of FIG.

In the figure, 1 is a writing instrument main body, 2 is a finger rest on the tip side of the body 1, 3 is a tip member screwed to the tip of the body 1, and 4 is an elastic cylinder made of a rubber material, respectively. The cylindrical body 4 may be made of synthetic resin.

[0008]

[First embodiment]

 In the first embodiment shown in FIGS. 1 to 3, the outer diameter of the finger rest 2 is made smaller than the outer diameter of the main body 1, and the rear end of the outer peripheral surface 2 ′ of the finger rest 2 has a finger rest. The pair of projecting edges 7 and 7 along the axial direction of 2 are provided at opposite positions, and the tip end is provided with a pair of recessed edges 8 and 8 at the position above the extension of the projecting edges 7 and 7. The recessed edges 9, 9 or the ridge edges 10, 10 are provided at both ends of the inner peripheral surface 4'of the elastic cylindrical body 4 so as to correspond to the protruding edges 7, 7 and the recessed edges 8, 8. The elastic tube body 4 is fitted into the finger contact section 2 by inserting the finger contact section 2 into the elastic tube body 4, and the elastic tube body 4 is recessed into the projecting edges 7, 7 of the finger contact section 2. The edges 9 and 9 are engaged with the recessed edges 8 and 8 and the projecting edges 10 and 10 are engaged, and the tip member 3 is screwed onto the tip of the main body 1 so that the tip member 3 and the body 1 are elastically coupled. The cylindrical body 4 is interposed.

[0009]

[Second embodiment]

 In the second embodiment shown in FIGS. 4 to 6, the outer diameter of the finger contact portion 2 is the same as the outer diameter of the main body 1, and the protruding edge 7 and the tip end portion are provided at the rear end on the finger contact portion 2 side. One recessed edge 8 is provided on each side, and a recessed edge 9 and a ridge edge 10 corresponding to these are provided on the elastic cylinder body 4 side, and the remaining points are almost the same as in the first embodiment. is there.

[0010]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the elastic cylinder does not pivotally move with respect to the main body, so that writing work can be performed smoothly.
