DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a black ink pot used for black ink in woodwork or construction.

[0002]

2. Description of the Related Art Ink pots 100 used by construction workers and the like are:
Conventionally, as shown in FIG. 7, for example, basically, a black ink thread 104 is wound around an outer periphery of a bobbin reel 103 urged in a bobbin winding direction by a spiral spring (not shown) in a bobbin case 101. The driving thread 104 is a main body case 1
No. 02, the ink is passed through the ink penetrating member 105 housed in the ink chamber 102S, and is fed out of the main body case 102 through the thread feeding port 102a. Thread feed port 1
The yarn hooking portion on the outer periphery of the black ink yarn 104a is rubbed with the black ink yarn 104a when the yarn is fed or wound.
In order to reduce the frictional load on
07 is provided, or the entire outer peripheral portion of the thread payout port 102a is formed of metal or ceramics. 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 black-inking operation using the above ink bottle 100, first, the karuko 106 is fixed to the starting point of black ink by piercing the piercing needle 106a into the surface A to be blacked. Is moved to a predetermined position, the black ink thread 104 wound around the spool 103 in the thread winding case 101 is fed out by the moving distance of the ink vase 100. In the feeding process, the ink penetrating member 105 in the main body case 102 is drawn out. The black ink held on the black ink yarn 104 is attached to the black ink yarn 104, and the black ink yarn 104 stretched between the sculpture 106 and the outer yarn hooking portion of the yarn feeding port 102a is removed.
It is performed in such a procedure that the black line is transferred by flicking and striking with a finger toward the black ink target surface A. After the blackening operation is completed, the spar 106 is pulled out from the surface A to be blackened by forcibly pulling the blackening yarn 104, and the spiral spring accumulated when the blackening yarn 104 is fed out. The urging force causes the wind reel 103 to rotate in the winding direction, whereby the black ink thread 104 is automatically transferred to the wind reel 103 until the swarf 106 is locked in the thread feed port 102a of the main body case 102. It is wound up.

[0004]

SUMMARY OF THE INVENTION A conventional structure of an inkwell 100.
In the above, as described above, the metal ring 107 is provided on the outer thread catching portion of the thread pay-out port 102a, or the entire outer peripheral portion of the thread pay-out port 102a is formed of metal, ceramics, or the like, so that it can be used for feeding or winding. As shown in FIG. 8A, such a metal ring 107 and a threaded portion made of metal or ceramic are also used to reduce the frictional load on Is repeatedly worn, causing wear during long-term use. Moreover,
A thread hooking groove 10 formed on the inner surface of the thread payout port 102a.
Since only the portion corresponding to the path of the black ink thread 104 by 2b is subjected to friction, as shown in FIG. 8B, the wear state of the metal ring 107 is such that the wear surface 107a forms a sharp edge. It becomes a shaved shape. Then, when the edge due to such abrasion is formed, the black ink thread 1
04 may be easily cut off by being hooked on this.

[0005] In addition, the conventional inkwell 100 includes a main body case 10.
The outer periphery of the second yarn feeding port 102a is formed in a substantially circular shape, or is formed with a certain width and thickness because the kawk 106 needs to be locked in a semi-accommodated state when not in use. For this reason, when the blackening starting point on the opposite side to the fastening portion by the spar 106 is present, for example, at the entry corner or the like, the blackening thread 104 is moved to the back of the narrow entry corner by the outer peripheral portion of the yarn feeding port 102a. It is difficult to hold down, so for example, as shown in FIG. 9, the finger is used dexterously to hold down the black ink thread 104 in the corner, or it is called a crane for exclusive use in the corner. An elongated hook (not shown) was required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and a technical problem thereof is to prevent cutting of a black ink thread due to abrasion of a thread hook portion into a sharp shape. Another technical problem is to improve the usability in a narrow space such as a corner.

[0007]

Means for Solving the Problems The inkwell according to the present invention is a means for effectively solving the above technical problems.
The periphery of the yarn feed-out port from which the black ink yarn is led out is formed of a wear-resistant resin material. In other words, even though the portion of the black ink thread around the yarn feed-out port is subjected to repeated friction with the black ink yarn, since this portion is made of a wear-resistant resin material, it is hard to wear, and However, since the abraded portion does not have a sharp shape, it is effective in preventing cutting of the black ink thread. In addition, as the wear-resistant resin material,
Typically, POM (polyacetal) is employed.

As another solution, an opening edge on the yarn feed-out port side from which the black ink yarn is led out is formed in a flat elongated hole shape, and a portion near the opening edge is a portion containing the ink chamber. It is formed to be thinner. This makes it possible to easily and accurately perform the work of stretching the black ink thread to a narrow place such as a corner. In addition, by providing an engaging portion with the flat elongated hole-shaped opening edge on the sculpture to be connected to the black ink thread, the sculpture can be hooked.

2c and 52d, and reaches a linear portion where the thread hook notch 54 is formed at the opening edge 53b.

Karuko 2 is a handle 2 made of synthetic resin such as ABS.
a and a piercing needle 2b having a base embedded and fixed in the handle 2a
And a protective material 2c made of synthetic resin such as ABS surrounding the outer periphery of the piercing needle 2b. The handle 2a is formed in a flat shape, and the end on the side of the piercing needle 2b is provided with a thread pay-out opening 53 of the top member 50 in a state where the black ink thread 3 is completely wound on the thread winding reel 30. Opening edge 53b of
And a pair of engaging projections 2a2 and 2a2 that can be inserted into the thread payout port 53 are formed. Further, the base 2c1 of the protective member 2c is locked between the engaging projections 2a2 and 2a2, the main body is formed in a coil spring shape, and only the sharp end of the piercing needle 2b protrudes from the tip of the main body. ing.

That is, by forming the handle 2a of the carcass 2 into a flat shape as described above and forming the engaging projections 2a2 and 2a2, the carcass 2 can be inserted into the thread feeding port 53 through the piercing needle 2b. Can be hooked on the flat yarn feed-out port 53 in a safe state, and in other words, by forming the bulge 2 as described above, the yarn feed-out port 53 of the ink vase 1 is provided. The end on the side can be formed into a tapered flat shape as shown in the figure.

In the above-described configuration, when black ink is to be performed, the piercing needle 2b of the sculptor 2 is pierced into one of the starting points of the black ink, and then the ink fountain 1 is moved to a predetermined position. The black ink thread 3 is fed by the moving distance of the ink fountain, and the opening edge 53b of the top member 50 of the black ink fountain 1 (the thread hook notch 54 or the thread hook 5
5), the black ink thread 3 to which the ink has adhered in the feeding process is stretched between the two starting points,
The ink line is transcribed by flicking and striking the surface with the finger toward the surface to be inked. After the completion of the blackening operation, when the black yarn 2 is pulled out from the surface (not shown) forcibly by pulling the black yarn 3 forcibly, the spiral spring 33 stored in the process of feeding the black yarn 3 is used. The urging force causes the reel body 31 to rotate in the yarn winding direction, whereby the black ink thread 3 is locked until the sparker 2 is half-housed in the yarn feeding port 53 of the top member 50 of the black pot 1. , Is automatically wound on the reel body 31.

In the above-described ink-inking operation, when the ink-inking yarn 3 is fed out, the thread notch 54 or the thread-engaging groove 55 in the top member 50 of the ink jar 1 receives friction with the ink-inking yarn 3. Since the member 50 is formed of POM having high wear resistance and high mechanical strength, the member 50 is hardly worn and has relatively small frictional resistance. In addition, even if the thread hook notch 54 or the thread hook groove 55 gradually wears out during a long-term use, the wear shape does not become a shape having a sharp edge as a result of an experiment conducted by the inventor. It takes on the shape. Therefore, it is possible to effectively prevent the black ink thread 3 from being easily cut by being caught by the worn portion of the thread hook notch 54 or the thread hook groove 55.

In addition, the end of the ink pot 1 on the side of the thread pay-out port 53 is formed to be tapered and gradually flattened toward the front end. The black ink thread 3 is moved to the black ink starting point P at a narrow corner as shown in FIG. 5, for example, by the thread notch 54 or the thread groove 55 of the opening edge 53b formed at the flat tip of the top member 50. Can be restrained. Therefore, the black ink starting point P on the opposite side to the fastening part by the carving 2 is
Accurate blackening can be performed even in the case where such a corner exists.

In the above embodiment, the end of the ink fountain 1 on the side of the yarn feeding port 53 extends from the main body case 10 to the top member 50, and the inclined surfaces 10c, 52c, 10d, 52d are formed.
However, as shown in FIG. 6, even if a flat portion is formed in a stepped shape from the end of the portion including the ink chamber 10S in the main body case 10 to the top member 50, as shown in FIG. The work of pressing down the black ink thread 3 in a narrow place such as the above can be easily performed.

[0029]

According to the ink fountain according to the present invention, the thread hooking portion around the thread payout port is not worn into a sharp shape due to friction with the black ink thread, so that the cutting of the black ink thread is effective. In addition, by forming the end on the yarn feed-out port side to be a flat protruding shape thinner than the portion containing the ink chamber, it is possible to improve the usability in a narrow space such as an entrance corner. Can be.
