The yarn is fed to the outside from the yarn feeding port 102a of the main body case 102 through the ink penetrating member 105 accommodated in the ink container. At the front end of the black ink thread 104 fed from the yarn feeding port 102a, a sword 106 for fixing to a black ink target surface A such as wood is attached.

[0003] In the above-described ink-inking operation using the ink pot, first, the karuko 106 is fixed to the starting point of the ink-inking by piercing the puncture needle 106a into the ink-inking target surface A. By moving to a predetermined position, the black ink thread 104 wound on the reel 103 in the thread winding case 101 is fed out by the moving distance of the main body case 102, and is held by the ink penetrating member 105 in the main body case 102 in the feeding process. The obtained ink is adhered to a black ink thread 104, and the black ink thread 104 stretched between the sculpture 106 and the main body case 102 is struck with a finger toward the black ink target surface A, thereby striking. This is performed by a procedure such as transferring the black line. After the completion of the inking operation, if the spar 106 is pulled out from the inking target surface A by forcibly pulling the inking yarn 104, the inking yarn 10
The reel 103 is rotated in the winding direction by the urging force of the spiral spring stored at the time of feeding of No. 4, whereby the black ink thread 104 is turned into
Reel 10 until it is locked in the thread feeding hole of the reel 10.
3 automatically wound up.

[0004]

In the above-described conventional ink jar, for example, the rotation of the reel 103 is stopped by pressing the handle 103a of the reel 103 with the black ink thread 104 being fed out by a predetermined length, or Thread 104
There is a problem that it is difficult to perform an operation of pressing the pressing member 102a for sufficiently adhering the ink in the process of extracting the ink.

The present invention has been made in view of the above circumstances, and a technical problem thereof is to provide a body case and a thread winding case, which constitute the outer shell of a sumo pot, with ease of use by giving each other a degree of freedom. Is to improve.

[0006]

Means for Solving the Problems As means for effectively solving the above-mentioned technical problems, the connection structure of the ink pot according to the present invention is such that the main body case and the bobbin case are arranged around the radial axis of the reel main body. Are pivotally connected via a pivoting ridge and a pivoting projection engaged with each other in a state in which relative rotation is possible, and the pivoting ridge is fitted with the pivoting projection at one or more locations in the circumferential direction. The holding recess and the pivot projection have a gap portion that can pass in the axial direction, and when the predetermined recess of the pivot projection and the pivot projection are relatively rotated in a certain direction, the pivot connection is made. The engagement between the ridge and the pivot projection is released.

[0007] According to the present invention, the main body case and the bobbin case are provided with an axial center extending in the radial direction of the reel main body because the pivot projection is relatively slidable in the circumferential direction of the pivot projection. It is pivotally connected so that relative rotation within a predetermined angle range is possible. Further, each time the main body case and the bobbin case are rotated relative to each other by a predetermined angle, the pivoting projection is fitted into the concave portion of the pivotal ridge, and an appropriate resistance to the relative rotation is generated. The case can be held at an appropriate angle. For this reason, when the operator uses the ink bottle while holding the main body case, the relative angle between the main body case and the axis of the reel main body can be arbitrarily changed, so that various operations at the time of use, for example, a spiral spring Operation of the clutch lever for releasing the urging, or operation of the thread press lever for sufficiently attaching the ink to the ink stroke, etc., is facilitated.

[0008]

The black ink thread 1 wound around the reel body 31 of the reel 30 passes through the thread insertion tube 14 and the black ink chamber 10S and is brought into contact with the sponge 12 impregnated with black ink, and from the thread feed port 15 to the outside of the main body case 10. Derived. Also,
A thread holding lever 16 is rotatably attached to the cover 13 via a shaft 17. When the outer end 16a is pushed by a finger, the lever 16 is rotated as shown by a broken line in FIG.
7, the inner end portion 16b forcibly presses the black ink thread 1 passing through the black ink chamber 10S and the sponge 12 into which the black ink has penetrated, so that the black ink sufficiently adheres to the black ink thread 1. . The reference numeral 13a in FIG.
Is a packing provided for preventing ink leakage.

At the paying-out end of the black ink thread 1 led out of the main body case 10 from the yarn feeding port 15, a sword 2 for piercing a mating material of black ink and fixing the black ink thread 1 is provided. Are tied up. In a state where the black ink thread 1 is completely wound on the reel 30, the sculpture 2 is engaged with the thread pay-out port 15 in a semi-accommodated state as shown by a two-dot chain line in FIG. 2.

The bobbin case 20 and the inner joint 21 integral therewith are divided into upper and lower parts, that is, an upper half case member 20A and a lower half case member 20B. The upper half case member 20A and the lower half case member 20B are engaged with engaging projections 22 and 23 projecting at 180 ° symmetrical positions with respect to the inner joint portion 21 in the circumferential direction, respectively. The joint portion 21 is assembled into a shape as a thread winding case 20 by fitting an O-ring 25 made of rubber into a large-diameter base portion 24 and binding the joint.

The reel 30 has a spring core 32 mounted on the inner periphery of the reel body 31 in a substantially concentric and relatively rotatable state, and one end is fixed to the reel body 31 and the other end is fixed to the spring core 32. And a spiral spring 33 for urging the reel body 31 in the winding direction of the black ink thread 1. The reel body 31 has a winding handle 34 formed on an inner peripheral portion on one side in the axial direction for winding the black ink thread 1 by manual rotation, and a circular window formed on an inner peripheral portion of the upper half case member 20A. A charge handle 35 is formed at an end of the spring core 32 facing the opposite side of the take-up handle 34 from the outside, and a circular window formed at the inner periphery of the lower half case member 20B. From the outside.

A ratchet gear (not shown) is formed on an outer peripheral surface of a portion of the charge handle 35 inserted into the bobbin case 20, and is formed on an inner peripheral surface of an annular ratchet member 36 arranged on the outer periphery. Is formed with a ratchet pawl (not shown), and the ratchet pawl is engaged with the ratchet gear to form a spring core 3.
2 (charge handle 35) can rotate only in the direction of energy accumulation of the spiral spring 33 with respect to the ratchet member 36. An abutment projection 36a is formed at one circumferential position of the ratchet member 36,
The abutting projections 36a are provided at the abutting projections 37a, which are provided at 180 ° symmetrical positions in the circumferential direction of the annular clutch member 37.
37b. The clutch member 37 is pressed in one direction by a coil spring 38, so that usually the ratchet member 3 is pressed.
The abutment projection 36a of 6 is prevented from rotating by abutment with one abutment projection 37a of the clutch member 37.

[0015] Therefore, the reel body 31 is
Is rotated in the feeding direction, the ratchet gear on the outer peripheral surface of the charge handle 35 engages with the ratchet pawl of the ratchet member 36 stopped by the clutch member 37, so that the spring core 32 in the feeding direction is rotated.
Is prevented from being rotated, so that the spiral spring 33 is
And gradually accumulate energy. If the charge handle 35 is rotated in the same direction as the yarn winding direction in a state in which the black yarn 1 is completely wound up until the spar 2 is locked to the yarn feeding port 15, the reel body 3
1 prevents the rotation of the charge handle 35 in the winding direction and the rotation of the charge handle 35 in the opposite direction due to the hook 2 being locked to the line pay-out port 15, so that the spiral spring 33 is It can be charged arbitrarily.

Normally, one abutting projection 37a of the clutch member 37 which abuts against the abutting projection 36a of the ratchet member 36 projects the clutch member 37 from a small hole on the lower surface of the lower half case member 20B. Clutch lever 3
When the coil spring 38 is displaced in the compression direction (right direction in FIG. 2) by manual operation of the contact projection 7c, the coil spring 38 is disengaged from the abutment projection 36a. For this reason, the ratchet member 36 is attached to the charge handle 35
(Spring core 32), the clutch member 37 rotates in the biasing direction of the spiral spring 33 and rotates by 180 °.
Abuts on the other abutted projection 37b and stops. next,
The biasing force of the coil spring 38 causes the clutch member 3
7 is returned to the normal position, the other abutted projection 37b is disengaged from the abutment projection 36a, so that the ratchet member 36 is again moved in the biasing direction by the spiral spring 33 together with the charge handle 35 (spring core 32). Rotate, 180
At the time of rotation, the abutment projection 36a is stopped by reengaging with the one abutment projection 37a. That is, by repeatedly repeating such an operation of the clutch member 37 via the clutch lever 37c, the spring core 32 moves in the direction of reducing the urging force of the spiral spring 33 by one.
Since it rotates intermittently by 80 °, the urging force of the spiral spring 33 can be arbitrarily reduced or completely released.

The outer joint portion 11 has a cylindrical shape, is welded to the end of the main body case 10 on the side of the bobbin case 20, and has a pivotal ridge extending in the circumferential direction on its inner peripheral surface. 18 are protruded. The pivoting ridges 18 are discontinuous at circumferentially 180 ° symmetrical positions corresponding to the left and right side surfaces of the main body case 10, that is, a pair of semicircular arcs are formed as shown in FIG. Each pivot ridge 18
Recesses 18a to 18c are formed in the vicinity of both ends in the circumferential direction and in the center in the circumferential direction of the side surface facing the main body case 10 side, respectively, so that the outer joint portion 11 is viewed from the outer end side (the side of the bobbin case 20). In this case, the body case 10
A stopper 18d extending toward the side is formed.

The inner joint portion 21 has a cylindrical shape that can be inserted into the inner periphery of the pivoting ridge 18 of the outer joint portion 11, and its axis is oriented in the radial direction of the reel 30. 20 is formed integrally with a part of the outer peripheral portion in the circumferential direction. A pair of pivoting projections 26 are provided on the outer peripheral surface of the distal end of the inner joint portion 21 at circumferentially 180 ° symmetrical positions corresponding to the axial direction of the reel 30. Each pivoting projection 26 connects the inner joint 21 to the outer joint 1.
Rotate appropriately when inserting it into the inner circumference of
By positioning the gap with the gap 18e between the opposed ends of the outer and inner joints 8 and 18, the inner joint can be passed through the gap 18e until the distal end surface 11a of the outer joint 11 comes into contact with the O-ring 25. After the part 21 is completely inserted into the outer joint part 11, the main body case 10 and the thread winding case 2
By rotating the outer joint portion 0 relative to the outer joint portion 11 and the inner joint portion 21 in the circumferential direction, each of the pivoting projections 26 is slidably engaged with the surface of the pivoting ridge 18 on the body case 10 side. As a result, the main body case 10 and the bobbin case 20 are pivotally connected.

In the above-mentioned connection state, the elasticity of the O-ring 25 acting in the direction of separating the outer joint portion 11 and the inner joint portion 21 from each other causes the pivoting projection 26 to be attached to the surface of the pivoting ridge 18 on the body case 10 side. They can contact each other with an appropriate load and slide with each other. Then, the main body case 10 and the bobbin case 20 are connected to the outer joint portion 11 and the inner joint portion 21.
Each time the O-ring 25 is reciprocally rotated in the circumferential direction by a predetermined angle, the pivoting projection 26 is formed by the elasticity of the O-ring 25 so that the concave portions 18a to 18
c to generate an appropriate resistance to the relative rotation.

The upper surface of the main body case 10 and the thread winding case 20
In the normal state in which the upper surfaces of the pivot projections 26
Are fitted in the concave portion 18b located at the intermediate portion of the pivoting ridge 18, so that the normal state is maintained.
From this state, the main body case 10 is turned 70 ° counterclockwise with respect to the thread winding case 20 as shown by a solid line in FIG. When it is moved, the pivoting projection 26 sliding with the pivoting ridge 18 is fitted into the concave portion 18c and held in the state shown by the solid line, and the further rotation in the counterclockwise direction is performed. , Are prevented by interference between the pivot projection 26 and the stopper 18d. Conversely, from the normal state, when the main body case 10 is rotated clockwise by 70 ° with respect to the thread winding case 20 as shown by a broken line in FIG. The pivot projection 26 fits into the recess 18a and is held in the state shown by the broken line. When the body case 10 is further rotated clockwise against the rotational resistance caused by the engagement between the pivot projection 26 and the concave portion 18a,
The pivot projection 26 moves to a position corresponding to the gap 18e,
Since the engagement state with the pivot projection 18 is released, the main body case 10 and the thread winding case 20 can be separated.
Therefore, the angle between the main body case 10 and the bobbin case 20 can be changed within a total range of 140 ° while maintaining the connected state.

In the ink fountain having the above-described configuration, as in the prior art, the sword 2 is pierced to the starting point of the ink wiping, and then the ink fountain is moved to a predetermined position. The black ink thread 1 to which the black ink is attached in the process is flicked and hit with a finger toward the black ink target surface, thereby performing the black ink work. Ink thread 1
If the urging force of the spiral spring 33 accumulated at the time of feeding is not released by the repetitive operation of the clutch lever 37c, the black ink thread 1 is forcibly pulled after the black ink work is completed, and the like. 2 is the surface to be ink-marked
When pulled out from the reel, the urging force causes the reel body 31 to rotate in the yarn winding direction.
The reel 2 is automatically taken up by the reel body 31 until the spar 2 is locked in the thread pay-out port 15 of the main body case 10.

In such an operation, for example, the thread press lever 16 is pressed with a finger or a spiral spring 33 to sufficiently attach ink to the ink thread 1 fed out.
The spring core 32 is swirled by a repetitive operation of the clutch lever 37c in order to prevent the spring core 33 from being excessively charged.
When performing various operations such as rotation in the urging force decreasing direction, the main body case 10 and the bobbin case 20 are fitted with the pivoting projection 26 and the concave portion 18a or 18c so as to facilitate these operations. It can be rotated to any angle within the allowable angle (140 °) defined by the combination.

The present invention is not construed as being limited to the illustrated embodiment. For example, contrary to the illustrated embodiment, the same effect can be realized by providing the pivot connection protrusion 26 on the inner peripheral surface of the outer joint portion 11 and the pivot connection protrusion 18 on the outer peripheral surface of the inner joint portion 21. . In addition, the number of recesses and their intervals are also arbitrary, and can be set to an allowable angle other than 140 °.

[0024]

As described above, according to the present invention,
Since the main body case and the bobbin case can be rotated relative to each other at an arbitrary angle, various operations can be easily performed in the process of feeding or winding the black ink yarn, and the usability is improved.
