A ball is rotatably assembled to the tip 4 of the writing lead 2.

The outer cylinder 10 is formed to be divided into two parts and the screw portion 18 is formed to be assembled to each other.

Although not shown in the figure at the upper end of the outer cylinder 10, it is possible to form a clip that can be inserted into the collar, it is also possible to form a clip on the rotary arm (20).

The upper end of the outer cylinder 10 has a through portion 19 is formed so as to communicate with the outside so that the moving cap 34 is one side (above) of the moving member 40 through the through portion 19. Touch the end.

The rotating arm 20 is formed so that the inner surface facing each other is in contact with the symmetrical outer peripheral surface of the outer cylinder (10).

In addition, fixing protrusions 23 are formed on inner surfaces of the rotary arms 20 that face each other, and fixing grooves 13 are formed on the outer circumferential surface of the outer cylinder 10 so that the fixing protrusions 23 are inserted into and rotated. The arm 20 and the outer cylinder 10 are fixed.

As shown in FIG. 6, the hinge protrusion 22 of the rotating arm 20 is formed in a cylindrical shape, and the hinge groove 12 of the outer cylinder 10 corresponds to the hinge protrusion 22. It is formed into a shape.

The end portion of the hinge protrusion 22 and the portion where the hinge groove 12 meets are preferably formed to be round so that rotation is smooth with each other.

The hinge groove 12 is formed to extend up and down along the longitudinal direction on the outer circumferential surface of the outer cylinder 10 so that the hinge protrusion 22 rotates while moving up and down along the hinge groove 12. It is also possible.

A moving hole 24 is formed at the center of the rotary arm 20 in contact with one end of the outer cylinder 10 to assemble the pressing cap member 30.

The pressing cap member 30 is a moving cap 34 which is supported to be movable along the longitudinal direction through the moving hole 24 and reciprocates the moving member 40, and the moving cap 34 It consists of a pressing piece 36 is assembled with the end protruding toward the opposite side of the moving member (40).

The moving cap 34 is inserted into the pressing piece 36 to form an assembly protrusion 35 on the outer circumferential surface to be integrally fixed, and to form the assembly protrusion 37 on the inner circumferential surface of the pressing piece 36 as well. It is preferable to assemble by interference fit.

The moving cap 34 is hollow so that the side in contact with the moving member 40 is configured to communicate with the outside.

Both ends of the second elastic member 32 are supported between the flat portion and the pressing piece 36 on which the moving hole 24 of the rotary arm 20 is formed.

In the central portion of the rotating member 50 is formed a through hole 59 through which air is introduced into the writing core 10 so that atmospheric pressure acts.

Although not shown in the lower portion of the rotating member 50, it can be configured to be integrally assembled with the opposite end of the tip 4 of the writing machine 2 to rotate together.

The outer peripheral surface of the moving member 40 is formed by dividing the moving protrusions 42 by dividing at a predetermined angle along the circumference.

On the outer circumferential surface of the rotating member 50 is divided by a predetermined angle along the circumference to protrude a number of knock protrusions 52 corresponding to 1/2 of the moving protrusion 42.

The upper surface of the knock protrusion 52 is formed of an inclined surface 53, and the bottom surface of the moving member 40 is formed with a plurality of triangular teeth 44 are coupled to contact with the inclined surface 53.

In the above, the teeth 44 are formed in the same number as the number of the moving protrusions 42 described above.

In addition, the inner surface of the outer cylinder 10 alternately forms the guide groove 62 and the guide projection 64 in which the movable projection 42 is inserted to be movable.

The bottom surface of the guide protrusion 64 is formed of an inclined surface 65 corresponding to the inclined surface 53 of the knock protrusion 52.

When the force that pressed the pressing piece 36 in the above state is removed, the pressing cap member 30 moves backward by the elastic force of the second elastic member 32, and the first elastic member The writing core 2 also moves backward by the elastic force of (6), and the inclined surface 53 of the knock protrusion 52 moves the inclined surface 65 of the guide protrusion 64 while the rotating member 50 moves backward. A predetermined angle rotates according to the sliding, and the backward movement of the rotating member 50 stops as the knock protrusion 52 is caught by the return preventing protrusion 66.

When the backward movement of the rotating member 50 is stopped as described above, the tip 4 of the writing lead 2 is in a writing state in which the state where the tip 4 is exposed to the outside is maintained.

In the writing state as described above (see FIG. 3), when the user writes and presses the pressing piece 36 again for storage, the rotating member 50 moves forward, and the knock protrusion 52 prevents the return. It is separated from the state in close contact with the projection 66.

At this time, the rotating member 50 is rotated again so that the knock protrusion 52 passes over the guide protrusion 64 and is located in the guide groove 62 in which the return preventing protrusion 66 is not formed. do.

When the pressing force of the pressing piece 36 is removed in the above state, the pressing cap member 30 is moved backward by the elastic force of the second elastic member 32, and the elastic force of the first elastic member 6 By the writing core (2) is moved backwards, in turn the rotating member 50 and the moving member 40 is moved backwards, the tip (4) end of the writing core (2) is completely inside the outer cylinder (10) A concealed release state (see FIG. 4).

As described above, as the pressing piece 36 is repeatedly pressed, the writing state (see FIG. 3) and the release state (see FIG. 4) are repeatedly made.

In the above description of the preferred embodiment of the safety knock-type writing instruments according to the present invention, the present invention is not limited to this, but the present invention is not limited to the utility model registration claims and the detailed description of the invention and the various modifications to be carried out within the scope of the accompanying drawings. It is possible and this also belongs to the scope of the present invention.
