[0005]

BRIEF DESCRIPTION A first embodiment with reference to the accompanying FIGS. 1 to 5. A flat portion 1a is formed in the outer wall of the shaft cylinder 1 in the axial direction, and the flat portion 1a is formed with a slit 2 on each side of which is provided a large number of opposed portions 2a each having a rectangular notch. I have.

A mounting portion 3 for a rod-shaped material A such as a lip collar, a crayon, a pass, an eraser, a cutter blade, etc. is provided in the barrel 1.
The slider 3 having “a” is slidably disposed.
The slider 3 has a mounting portion 3a for the rod-shaped object A,
The retraction preventing portion 3b having the projection 3d serving as the locking portion is connected by a plate-shaped portion 3e which is an elastic body on the side (downward position) facing the engaged portion 2a. Further, the retraction preventing portion 3b and the slider body 3c are connected by a plate-like portion 3f which is an elastic body on the side (upper position) close to the engaged portion 2a.

Further, inside the retracting portion 3b and the slider body 3c, an engaged portion 2a formed on the shaft cylinder 1 is provided.
Body having an engaging portion 4a capable of engaging with the elastic member (such as a leaf spring)
4 are arranged in a mountain shape. The engaging portion 4a of the elastic body 4 has a hole 3 provided at the center of a plate-like portion 3f connecting the retracting preventing portion 3b and the slider body 3c.
Through g, it can be engaged with the engaged portion 2a formed on the barrel 1. The knob 5 of the clip 6 is fixed to the slider body 3c by a leg 5a extending downward through the slit 2.

At this time, the engaging portion 4a only needs to be a convex portion that can be inserted into the engaged portion 2a. However, in consideration of the operability at the time of extension and storage, the engaging portion 4a has a curved surface. Alternatively, it is desirable to be formed of an inclined surface. Further, from the viewpoint of preventing the rod-shaped object A from being retracted, it is preferable that the projection 3d serving as the locking portion has a curved surface or an inclined surface in the feeding direction and a substantially vertical surface in the housing direction. In addition, the shaft cylinder 1
As for the cross-sectional shape of, other shapes such as a square shape and a flat shape can be adopted as appropriate.

Next, the method of use will be described. In FIG. 2 showing the stationary state, since the retraction preventing part 3b does not receive any force from the mounting part 3a and the slider main body 3c, the convex part 3d as the locking part is locked with the engaged part 2a. I haven't. In addition, when a pressing force is applied in the moving direction in order to feed or house the rod-shaped material A, the engaging portion 4a is displaced in the axial direction (that is, inward in the radial direction), and Although the engagement with the portion 2a is released, only the force in one direction acts on the retraction preventing portion 3b at this time, so that the protrusion 3d as the locking portion is locked with the engaged portion 2a. Is not configured. In use, that is, in a state in which the rod-shaped material A protrudes and is in contact with the paper surface, a reaction force equivalent to a pressing force on the paper surface is applied. Accordingly, a force acts on the slider 3 in the direction in which the rod-shaped material A is stored. However,
Since the engaging force formed by the engaged portion 2a and the engaging portion 4a is acting on the slider body 3c, the retracting prevention portion 3b receives a clamping force by the mounting portion 3a and the slider body 3c, and is displaced radially outward. Then, a locked state is formed by the engaged portion 2a and the convex portion 3d as the locking portion (see FIG. 5). Thereby, the retraction of the rod A can be prevented. After use, when the stick A is separated from the paper surface,
Since the reaction force is also lost, the retracting preventing portion 3b returns to the original state, and the engaged portion 2a and the convex portion 3d serving as the locking portion are returned.
Is released, and the rod A can be easily accommodated.

Next, a second embodiment will be described with reference to FIGS. In the second embodiment, a plate-like portion 3e of an elastic body that connects the mounting portion 3a of the slider 3 and the retraction preventing portion 3b is on the side close to the engaged portion 2a, and the retraction preventing portion 3b, the slider body 3c Is located on the side facing the engaged portion 2a, and
The operation is the same as that of the first embodiment except that the protrusion 3d serving as the locking portion is formed on the attachment portion 3a side of the retracting prevention portion 3b, and the operation and effect are substantially the same.

Next, a third embodiment will be described with reference to FIGS. In the third embodiment, an elastic plate-shaped portion 3e for connecting the mounting portion 3a of the slider 3 to the retractable portion 3b, and the retractable portion 3b and the slider body 3
c and the elastic plate-like portion 3f are both formed on the side close to the coupled portion 2a, and therefore, the convex portion 3d serving as the locking portion is substantially at the center of the retracting prevention portion 3b. Except for being formed, it is the same as the first embodiment, and the operation and effect are also substantially the same.

Next, a fourth embodiment will be described with reference to FIG. In the fourth embodiment, the slider mounting portion 3a and the slider main body 3c are connected by a retraction preventing portion 3b made of an elastic plate, and a protrusion 3d serving as a locking portion is provided substantially above the center of the retraction preventing portion 3b. It is formed. The fourth embodiment is the same as the first embodiment except that the retraction preventing portion 3b is formed to be curved in an arc shape and the convex portion 3d is formed outside the arc. Is substantially the same.

Incidentally, in FIG. 10, the retracting prevention portion 3b
Has shown only one example, but two may be provided. In this case, the second retractable portion 3b is provided so as to connect the mounting portion 3a of the rod A to the lower position of the slider body 3c. A protruding portion 3d, which is a locking portion, is formed substantially below the center of the retraction preventing portion 3b. In this case, since the convex portion 3d, which is the downward locking portion, comes into contact with the inner wall of the shaft cylinder 1 to generate frictional resistance, the rod A can be more reliably prevented from being retracted.
Furthermore, depending on the type of the rod-shaped material A, the retraction may be prevented to some extent only by friction between the retraction preventing portion 3b and the inner wall of the barrel. In such a case, the retraction preventing portion 3b may be used.
The protrusion 3d need not be formed in b.

Next, a fifth embodiment will be described with reference to FIG. In the fifth embodiment, the slit 2 and the engaged portion 2a formed of a number of holes are formed so as to face each other in the barrel 1. Therefore, the knob 5 is mounted in the direction opposite to the engaged portion 2a. Except for this, the configuration, operation and effect are the same as those of the first embodiment. The engaged portion 2a may be a hole other than the illustrated example.

Next, a sixth embodiment will be described with reference to FIGS. In the sixth embodiment, the slider 3 elastically connects a retractable portion 3b, which is formed with a convex portion 3d, which is a locking portion, to the mounting portion 3a of the rod-shaped object A by a plate-shaped portion 3e. The slider body 3c is elastically connected to the portion 3b by a plate-like portion 3f. Further, a resilient body 4 such as a leaf spring having an engaging portion 4a capable of engaging with the engaged portion 2a formed on the shaft cylinder 1 is arranged inside the slider main body 3c so as to have a mountain shape. I have. The engaging portion 4a of the elastic body 4 protrudes from a window 3g provided on the side wall of the slider body 3c so as to be able to engage with the engaged portion 2a of the shaft cylinder 1. The part 4b is in contact with the inner wall of the slider body 3c. Other configurations are the same as in the first embodiment.

The method of use is as described in the first embodiment (for example,
Although the detailed description is omitted because it is the same as FIG. 2, a reaction force equivalent to the pressing force on the paper surface is applied during use, that is, in a state where the rod-shaped object A is protruding and abutting against the paper surface. I have. Accordingly, a force acts on the slider 3 in the direction in which the rod-shaped material A is stored. However, since the slider body 3c is subjected to the engaging force of the engaged portion 2a and the engaging portion 4a, the retraction preventing portion 3b receives the clamping force by the attaching portion 3a and the slider body 3c, and moves outward in the radial direction. It is displaced, and a locked state is formed by the engaged portion 2a and the convex portion 3d as the locking portion (see FIG. 5). Thereby, the retraction of the rod A can be prevented.

Further, when a pushing force is applied to the knob 5 fixed to the slider body 3c in the moving direction side in order to extend and accommodate the rod-shaped material A, the engaging portion 4a of the elastic body 4
Is displaced in the axial direction (that is, inward in the radial direction) against the elastic force, the engagement with the engaged portion 2a is released, and the slider 3 moves, so that the engaged portion is displaced. It enters the engaged portion 2a next to 2a. At this time, both shoulders 4b of the repellent body 4 collide with the inner wall of the slider body 3c and emit a light collision sound, so that a comfortable operation feeling can be obtained. Moreover, since the inner wall of the slider body 3 can be made thicker, it can withstand long-term use.

[0018] Next, the seventh with reference to FIG. 15 view and FIG. 16
An embodiment will be described. In the seventh embodiment, the slider 3
Is a plate-like portion 3e extending behind the mounting portion 3a of the rod-shaped material A.
Anti-retraction part 3b formed with a convex part 3d as a locking part
Are connected rotatably by a connecting member 3h such as a bolt or a screw, and furthermore, the retractable portion 3b and the slider body 3c are rotatably connected by a connecting member 3f and connecting members 3j and 3k such as a bolt or a screw. Connected. Although the plate-like portion 3e has been described as an example in which the plate-like portion 3e is integrated with the mounting member 3a, the plate-like portion 3e may have a separate structure. In the case of separate configuration,
The attachment portion 3a and the plate-like portion 3e may have a fixed connection structure or may be rotatably connected. Other configurations are the same as in the first embodiment .

Since the method of use is the same as that of the first embodiment, a brief description will be given. When the rod-shaped object is used, a reaction force equivalent to the pressing force on the paper surface acts on the rod-shaped object, so that a force in the direction in which the rod-shaped object A is accommodated acts on the slider 3. However, on the slider body 3c, an engaging force is exerted on the engaged portion 2a of the barrel 1 and the engaging portion 4a of the elastic body 4. Then, the retraction preventing portion 3b receives a clamping force by the mounting portion 3a and the slider body 3c,
Displaced outward in the radial direction, the engaged portion 2a of the barrel 1 and the projection 3d serving as the locking portion form a locked state. Thereby, retraction at the time of use of the rod-shaped material A can be prevented.
After use, when the rod-shaped material A is separated from the paper surface or the like, the reaction force is also lost, the pressing force between the engaged portion 2a of the barrel 1 and the convex portion 3d as the locking portion is lost, and the retracting prevention portion 3b is It returns to the original state, the locked state is released, and the rod A can be easily accommodated. In this embodiment, the plate-like member 3e and the connecting portion 3f
Can be formed separately from each other, so that the material can be freely selected, so that the mechanical strength of the slider can be increased as required, and a configuration that can withstand long-term use can be achieved.
