[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for feeding a rod-shaped material such as a rubber eraser, a lipstick, a marker, an eye shadow, a writing lead and the like, which can be retracted after use.

[0002]

2. Description of the Related Art A conventional rod feeding device will be described with reference to FIG. 1. A rod guiding member 2 having a head portion 1 is provided with a guide slit 3, and a rod 4 is held between the guide slits 3. The holding piece 6 of the bar-shaped object receiving base 5 is slidably fitted, and the projection 7 of the holding piece 6 is screwed into the spiral groove 9 of the spiral member 8.
, And by rotating the spiral member 8, the rod-shaped object receiving base 5 advances or retreats along the guide slit 3 of the rod-shaped object guide member 2, and the rod-shaped object 4 moves the head 1 of the rod-shaped object guide member 2. It is configured to protrude or retract more.

[0003]

In the above-mentioned prior art, since the holding piece 6 does not protrude from the head 1 of the stick guide 2, the holding piece 6 is held by the holding piece 6 of the stick receiving base 5. There is a problem that the remaining rod-shaped material cannot be easily taken out.

[0004]

Since the present invention apparatus SUMMARY OF THE INVENTION To solve the above problems, a a plurality of guide slits 3 in the stick-shaped material guide member 2 having a head 1, as shown in FIG. 1, the respective <br The rod-shaped object receiving table 5 for holding the rod-shaped object 4 in the guide slit 3
Are slidably fitted to each other, and the protrusions 7 of the
Is inserted into the spiral groove 9 of the spiral member 8 in the rod feeding device. The guide groove 10 is connected to the guide slit 3 and projects the holding piece 6 from the head 1 at the most advanced position.
Is provided on the inner surface of the head 1.

[0005]

With such a construction, the holding piece 6 of the bar-shaped object receiving base 5 can be protruded from the head 1 through the guide groove 10 in the inner surface of the head 1 of the bar-shaped object guide member 2, thereby holding the bar. The remaining rod-like material held between the pieces 6 can be easily taken out.

[0006]

FIG. 1A is a longitudinal sectional view showing the structure of the first embodiment of the present invention in a state in which a holding piece is retracted.
FIG. 2B is a perspective view showing a state in which the holding pieces protrude, FIG.
FIG. 2 is a partially exploded perspective view of the first embodiment. In the drawing, reference numeral 2 denotes a rod-shaped object guide member having a head 1, reference numeral 3 denotes a guide slit provided at an opposing portion of the guide member 2, and reference numeral 5 denotes a rod-shaped object receiving table having two holding pieces 6 for holding a rod-shaped eraser 4. Each holding piece 6 is slidably fitted in the guide slit 3. Reference numeral 7 denotes a protrusion provided on both holding pieces 6, which is fitted into the spiral groove 9 of the spiral member 8.

In the first embodiment, in such a rod feeding device, two guide grooves 10 connected to the two guide slits 3 and projecting the two holding pieces 6 from the head 1 at the most advanced position are provided inside the head 1. Are provided in opposing portions.
A cut 11 is formed at the end of the rod-shaped object guide member 2 on the side opposite to the head.
The bar-shaped object guide member 2 is
The end on the opposite side of the head is bent inward, and the rod-shaped object guide member 2 is screwed.
It is inserted into the turning member 8. Also, use the guide slit 3
To guide the rod-shaped object guide member 2 outward,
A rod-shaped receiving table 5 is inserted into the material 2.

In the case of the first embodiment, the spiral member 8 is formed by fitting a coil body 8B forming a spiral groove 9 in a cylindrical body 8A, but the spiral groove 9 is formed on the inner surface of the cylindrical body 8A. It may be formed. Four notches 12 are formed at the end of the bar-shaped object guide member 2 on the opposite side of the head, and a locking claw 13 is provided outside the distal end of each of the notches 12. A plug 14 for spreading the piece 12 outward is fitted. One tongue piece 15 is formed at the rear of the cylindrical portion 8A,
A projection 16 is provided outside the tip of the tongue piece 15.

In the first embodiment having the above structure, when the head 1 of the rod guide member 2 is rotated with respect to the cylindrical body 8A of the spiral member 8, the guide slit 3 of the rod guide member 2 is formed.
The holding piece 6 of the rod-shaped receiving table 5 is slidably fitted, and the projection 7 of the holding piece 6 has a spiral shape of a coil body 8B fitted in a cylindrical body 8A constituting a spiral member 8. Since the rod-shaped object receiving table 5 is fitted into the groove 9, the rod-shaped object receiving table 5 advances or retreats according to the rotation direction along the guide slit 3 and the guide groove 10 of the head 1 by the spiral groove 9, whereby the rod-shaped object receiving table 5 is moved. The rod-shaped eraser 4 clamped between the clamping pieces 6 is the head 1 of the rod-shaped object guiding member 2.
It will be able to protrude and retreat more.

[0010] The rod-shaped eraser 4 is reduced by use, and the holding piece 6 of the rod-shaped object receiving stand 5 becomes a rod-shaped object guide member 2 as shown in FIG.
Projecting from the head 1 through the guide groove 10 on the inner surface of the head 1, and the remaining rod-like material held by the holding piece 6 can be easily taken out.

Since the present embodiment has the above configuration,
Since the cut 11 is provided in the rod-shaped object guide member 2,
When the rod-shaped object guide member 2 is inserted into the spiral member 8, the
Since the portion 11 is easily bent inward, this cut 11
Utilizing this, the rod-shaped object guide member 2 is brought closer to the spiral member 8.
It can be easily inserted.
