[0001]

BACKGROUND OF THE INVENTION The present invention relates to an automatic winding type ink pot used by carpenters and masons to draw black lines on wood, walls, floors and stone materials.

[0002]

2. Description of the Related Art A hand-type ink bottle shown in Japanese Utility Model Publication No. 1-23749 has been developed for the conventional old ink bottle, but this hand-type ink bottle is wound around the outer periphery of a wound drum. When the rotated ink thread is pulled out from the ink pot main body, the mainspring spring installed in the thread winding drum is urged,
A structure is adopted in which when the hand is released from the ink thread, the ink thread is automatically rewound to the outer periphery of the bobbin drum. When it became difficult, he had to remove the spool from the ink bottle body and fix the ink. At that time, there was a handling problem such as the spring being momentarily opened by the urging force of the spring, and the spring becoming weak.

[0003] Therefore, in the Japanese ink bottle disclosed in Japanese Utility Model Publication No. 3-54874, a knob member is provided to release the tight winding of the mainspring interposed between the cylindrical shaft portion and the inner peripheral wall of the mainspring spring accommodating portion of the bobbin drum. A release mechanism composed of a ratchet member and a clutch lever is attached to the ink bottle main body, and the clutch lever is slid once to partition the loose rotation of the mainspring by a half turn to release the close-wound winding of the mainspring. However, this mechanism has to operate the clutch lever to catch the fingernail and release the winding drum half a turn at a time, so that the claw hurts and the trouble of having to intermittently operate the half turn at a time The structure was quite complicated.

The present invention solves the above-mentioned drawbacks, and provides a normal protruding claw and a normal immersion claw on the inner wall of the storage section whose protruding / retracting state is reversed by a push button exposed to the outside of the storage section. By operating the push button, the locking claw of the stop rotating plate is alternately rotated and brought into contact with the normal protruding claw and the normal immersion claw sequentially, so that the locking body is allowed by the one-way rotation permissible claw of the stop rotating plate. It is an object of the present invention to provide an automatic winding type ink pot that is rotated and stopped to gradually release the biasing force of a mainspring.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

To be provided.

A rotating body 24 provided with a plurality of (four in the figure) engaging step portions 24 'in the shape of a ratchet wheel as shown in FIG. The first bearing portion 3 'is provided so as to be rotatable in a retaining state. The stop rotating plate 22 is fitted on the rotating body 24, and the rotation of the thread winding drum 2 as shown in FIG. The locking shaft 23 is provided clockwise as viewed from the Z direction in FIG. 1 (the direction in which the black thread 5 is pulled out for the bobbin drum 2 and the Is a direction in which the mainspring spring 4 is urged when the locking shaft 23 is stopped. The same applies to the following description.) When rotating, the rotating body 24 and the one-way rotation allowing claw 18 are locked and rotated together, When the locking shaft 23 rotates counterclockwise, the rotating body 24 is provided so as to rotate counterclockwise due to elastic deformation of the one-way rotation allowing claw 18 of the stop rotating plate 22.

A locking claw 25 is protrudingly provided on the surface of the stop rotating plate 22. When the locking shaft 23 rotates clockwise, the rotating body 24 is locked by the one-way rotation allowing claw 18 (FIG. 5). A point) Since the stop rotation plate 22 is rotated clockwise, the stop rotation plate 22 is rotated.
The locking shaft 23 rotates clockwise until the locking claw 25 of FIG. 5 abuts on the normal projection claw 20 (point B in FIG. 5).

A protruding tongue piece 28 is provided on the inner wall surface of the storage section 3 as shown in FIG. , And is provided so as to prevent the stop rotation plate 22 from rotating counterclockwise.

Since the embodiment is constructed as described above, when the black thread 5 is pulled out from the bobbin drum 2, the bobbin drum 2 rotates clockwise, and the mainspring 4 and the locking shaft 23 both try to rotate clockwise. However, the locking step 2 of the rotating body 24
4 'is locked to the one-way rotation allowing claw 18 of the stop rotation plate 22, and the locking claw 25 is locked to the normal protruding claw 20 to prevent rotation. Then, the bobbin drum 2 rotates and the mainspring spring 4 provided inside the bobbin drum 2 is urged. The black thread 5 is pulled out against the urging force of the mainspring 4, and when the power is released, the bobbin drum 2 rotates counterclockwise due to the urging force of the mainspring 4, and the black bobbin 5 is wound around the bobbin drum 2 and stored. .

At this time, the locking shaft 23 tends to rotate clockwise by the urging force of the mainspring 4, but as described above, the locking shaft 23 is rotated by the rotating body 24, the one-way rotation allowing claw 18,
The rotation is prevented by the locking claw 25 and the normal projection claw 20, and the locking shaft 23 does not rotate.

When the urging force of the spring 4 urged by pulling out the ink thread 5 from the ink pot main body 1 is released, the ink thread 5 is first wound around the winding drum 2 by the urging force of the spring 4. In order to prevent this, the disc portion 2 ′ exposed to the outside of the bobbin drum 2 is pressed, and the push button 19 is pushed with one finger to push the normal projection claw 21 from the inner wall surface of the storage portion 3 so that the normal projection claw When the protrusion 21 is projected from the wall surface (FIG. 6), the locking step 24 'of the rotating body 24 is locked on the contact surface (point A) of the one-way rotation allowing claw 18 and the spring 4 is rotated.
As shown in FIG. 6, the locking claw 25 of the stop rotating plate 22 is locked by the protruding normal immersion claw 21 (point C in FIG. 6). Therefore, the locking shaft 23 rotates by the angle θ ゜ as compared with FIG. 5, and the urging force of the mainspring spring 4 decreases by the rotation angle θ ゜.

Next, when the pressing of the push button 19 is released, the normal immersion claw 21 is immersed from the wall surface, and the state projection claw 20 is released.
Projecting from the wall surface, the contact surface (point A) of the rotating body 24 and the one-way rotation allowing claw 18 is rotated clockwise by the urging force of the mainspring 4 in the same manner as described above, and the locking claw 25 is projected. As shown in FIG. 5 (point B in FIG. 5), the locking shaft 23 further rotates as compared with the previous state, and the spring spring 4 is attached by that amount. Power is reduced.

As described above, by repeatedly pushing and releasing the push button 19, the urging force of the mainspring 4 for winding the black thread 5 onto the bobbin drum 2 can be sequentially released in a stepwise manner. When the ink thread 5 is cut or entangled unfortunately when the ink thread 5 is stretched on the workpiece and the ink line is drawn, the urging force of the mainspring spring 4 is released by pushing and releasing the push button 19, Then, the broken ink thread 5 can be connected and loosened, and the tangled ink thread 5 can be loosened, so that the work can be performed safely.

When the length of the black thread 5 wound on the bobbin drum 2 is longer than the feeding length of the mainspring spring 4 by winding the mainspring 4, when the black thread 5 is pulled out longer than a predetermined length, the mainspring 4 is brought into a substantially close contact state. When it is desired to pull out the ink thread 5 having a length longer than that, the close-winding of the mainspring 4 is released by the push button 19 as described above, and the ink thread 5 having a length corresponding to the release is released. Can be pulled out from the bobbin drum 2.

A knob 29 is provided in the outer exposed end of the flange portion 23 'of the locking shaft 23. When the knob 29 is rotated counterclockwise in FIG. When the knob 29 is rotated in the counterclockwise direction to apply the initial urging force of the mainspring 4 or when the number of turns of the mainspring 4 around the locking shaft 23 is small and the urging force is weak, The urging force of the mainspring 4 can be freely adjusted by rotating the knob 29 in a counterclockwise direction.
