Abstract

PROBLEM TO BE SOLVED: To prevent a dangerous condition owing to flying of a marking thread end fixture when a marking thread is wound on a reel main body which is rotated by the urging force of a spiral spring. SOLUTION: A mass body 40 is connected to a part in the circumferential direction on the outer periphery of a reel main body 31, in the condition to allow the fluctuation of the mass body 40, in the radius direction of the reel main body 31 by making the axis 31a as the center. To the mass body 40, a sliding part 42 slidable with the inner peripheral surface 26 of a bobbin winding case 20 is formed. Since the center of gravity of the reel main body 31 is decentralized by the mass body 40, and when it is rotated in the bobbin winding direction by the energizing force of a spiral spring, a vibration is generated in the diameter direction following the rotation, it is fluctuated to the outer peripheral side by the centrifugal force of the mass body 40, and the sliding part 42 is slided with the inner peripheral surface of the bobbin winding case 20. As a result, the increase of the rotating speed is suppressed, and the flying in of a marking thread end fixture 2 is prevented.

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 As a typical conventional example of a black pot used by a construction worker or the like, as shown in FIG. 5, for example, as shown in FIG. Outer black ink thread 10 of reel 103
4 and the black ink thread 104 is
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]

According to the conventional ink jar,
For example, in the process of the inking operation, the karoko 106 may accidentally fall out of the inking target surface A, or the kerko 106 may be pulled out of the inking target surface A by pulling the inking thread 104 after the inking operation. At the time of pulling out, the longer the feeding length of the black ink thread 104, the faster the rotation of the reel 103 in the thread winding direction. Therefore, in such a case, as shown by a dashed line in FIG.
In No. 6, the piercing needle 106a flies in a state facing the ink fountain side, and there is a danger that the piercing needle 106a may pierce the hand or the like of the worker holding the ink fountain.

The present invention has been made in view of the above circumstances, and a technical problem of the present invention is to prevent a danger caused by the flying of a black ink thread when it is wound on a reel. It is in.

[0006]

Means for Solving the Problems As means for effectively solving the above-mentioned technical problems, in the ink pot according to the present invention, the center of gravity of the reel body is set to a part of the outer peripheral portion of the reel body in the circumferential direction. It is decentered by the provided mass body. Therefore, when the reel body is rotated in the yarn winding direction by the spiral spring stored when the black ink is fed, the reel body whose center of gravity is biased by the mass body rotates with radial vibration (rack). That is, an increase in the rotational speed is suppressed by converting a part of the rotational movement into a radial movement. For this reason, the danger that the black ink thread is wound up relatively slowly and the swarf at the tip flies toward the ink jar side is effectively prevented.

In the present invention, more preferably, the mass body for biasing the center of gravity of the reel body has one end pivotally supported on the outer peripheral portion of the reel body so that the reel body can swing in the radial direction. In addition, the rocking makes it possible to contact the inner peripheral surface of the thread winding case. That is, according to this configuration, when the reel body rotates in the line winding direction, the reel body whose center of gravity is deviated due to the mass body rotates with radial vibration in the same manner as described above, thereby suppressing an increase in rotation speed. In addition, the free end of the mass body swings to the outer peripheral side due to centrifugal force, so that one side comes into contact with the inner peripheral surface of the bobbin case, and the resulting frictional resistance also acts as a suppressing force for increasing the rotational speed. I do. Moreover,
As the rotation speed increases, the frictional resistance between the mass body and the inner peripheral surface of the thread winding case due to the centrifugal force increases, so that the speed of the reel winding rotation of the reel body can be effectively suppressed.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a bottom view of an embodiment of the ink basin according to the present invention as viewed from a direction normally downward, and FIG.
FIG. 3 is a sectional view taken along the line II-II ′ of FIG.
These sectional views are taken along the line II-O-III '. In these figures, reference numeral 10 denotes a main body case, 20 denotes a thread winding case, and 30 denotes a reel rotatably housed in the thread winding case 20. A cylindrical outer joint part 11 protrudes from one end of the main body case 10, and a cylindrical inner joint part that can be inserted into the inner periphery of the outer joint part 11 at a part of the outer periphery of the bobbin case 20 in the circumferential direction. The main body case 10 and the bobbin case 20 are detachably attached to each other by inserting the inner joint portion 21 into the outer joint portion 11 and rotating each other in a predetermined direction. Are connected so as to be rotatable around.

In the main body case 10, a black room 10S filled with a sponge 12 as a black ink penetrating member is formed. The black room 10S is used to refill the sponge 12 with black ink. The cover 10 can be opened and closed by a cover 13 detachably fitted to a normally upper portion of the cover 10. Body case 10
The ink room 10S
A thread insertion tube 14 protruding inward is provided, and a funnel-shaped thread feed port 15 protruding into the ink chamber 10S is provided at an end opposite to the thread winding case 20.

The reel 30 in the bobbin case 20 has a reel body 31. The black ink thread 1 wound on the reel body 31 passes through the thread insertion tube 14 and the black room 10S and is sponge impregnated with black ink. 12 and the yarn feeding port 1
5 is led out of the main body case 10. Further, a thread press lever 16 is rotatably attached to the cover 13 via a shaft 17.
When the finger 6a is pressed by a finger, it rotates about the shaft 17 as shown by the broken line in FIG. 2 so that the inner end 16b forcibly separates the black ink thread 1 passing through the ink chamber 10S and the sponge 12 impregnated with black ink. Pressing is performed so that the ink is sufficiently adhered to the ink thread 1. Reference numeral 13a in FIG. 2 denotes a packing provided on the cover 13 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.

A mass body 40 made of an elongated metal piece is provided on a part of the outer periphery of the reel body 31 in the circumferential direction. When the small hole formed at one end 41 is inserted into a shaft 31a formed on one side plate of the reel body 31, the mass body 40 swings around the shaft 31a in the radial direction. The edge facing the outer peripheral side of the reel body 31 has a shape in which a portion unevenly distributed toward the one end 41 protrudes, so that this portion is formed in the lower half of the thread winding case 20. A sliding portion 42 slidable on the inner peripheral surface 26 of the case member 20B is provided.
Are formed in an arc shape curved in the circumferential direction.

That is, since the mass body 40 is provided in a part of the outer circumference in the circumferential direction, the center of gravity of the reel body 31 is slightly displaced from the axial position to the mass body 40 side. Therefore, a radial vibration is generated at the time of rotation. When the reel body 31 rotates, as shown in FIG. 4, the mass body 40 swings to the outer peripheral side around the shaft 31a by centrifugal force, and the sliding portion 42 of the mass body 40 is moved to the lower half case member 20B of the thread winding case 20. Slides with the inner peripheral surface 26 of the.

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 stroke, 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. After the blackening operation is completed, when the blackening thread 1 is forcibly pulled or the like, and the spar 2 is pulled out from the surface to be blackened (not shown), the spiral spring accumulated when the blackening thread 1 is fed out is accumulated. The urging force of 33 causes the reel body 31 to rotate in the yarn winding direction, whereby the black ink thread 1 is applied to the reel body 31 until the swarf 2 is in a state of being locked in the thread payout opening 15 of the main body case 10. It is automatically wound up.

In the above-described yarn winding process, when the rotation of the reel body 31 rotating in the yarn winding direction is accelerated,
In the reel body 31 whose center of gravity is deviated by the mass body 40, radial vibration is generated with rotation, and a part of the rotational force is converted into radial movement, so that an increase in rotational speed is suppressed. . The deceleration effect thereby becomes more remarkable as the amount of eccentricity of the center of gravity of the reel body 31 due to the mass of the mass body 40 increases.

The mass body 40 swings around the shaft 31a toward the outer periphery by centrifugal force, and its sliding portion 42 slides on the inner peripheral surface 26 of the lower half case member 20A of the bobbin case 20. Therefore, the frictional resistance generated thereby also suppresses an increase in the rotational speed. In addition, the sliding portion 42 is formed at a position from the shaft 31a, which is a fulcrum, and generates a large frictional resistance due to the leverage. This frictional resistance increases as the mass of the mass body 40 increases and the rotational speed increases. It increases as the speed increases. Therefore, even if the ink thread 1 is drawn out long to strike a long ink line, the ink thread 1
During the winding, the acceleration of the rotation of the reel body 31 is limited, and the danger that the carcass 2 flies toward the ink jar side is effectively prevented.

The present invention is not construed as being limited to the illustrated embodiment. For example, the mass 40
Is provided integrally with a part of the reel body 31 in the circumferential direction so that the center of gravity of the reel body 31 is eccentric to generate radial vibrations during rotation. Rotation or increase in rotation speed can be effectively limited. In the above embodiment, the mass 40
Is made of a metal piece, but may have a structure in which a high specific gravity material such as lead is integrated near the free end of a rocking piece made of synthetic resin, for example.

[0023]

As described above, according to the ink fountain of the present invention, the acceleration of the rotation of the reel is restricted during the automatic winding of the black ink yarn by the urging force of the spiral spring. It is possible to prevent the lump at the tip from flying toward the ink jar side, or to significantly reduce the flying speed, thereby improving work safety.
