Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of an ink pot used as a carpenter's tool.

[Conventional technology]

Conventionally, a reel for storing yarn is inserted into a case by a shaft, and an ink chamber is formed through a partition wall with respect to the reel housing part, and ink ink such as ink cotton is permeated into the ink chamber. There is a known ink pot which is filled with material and has thread insertion holes bored in the partition wall and the outer end wall of the inking chamber, and the thread is drawn out by passing through the thread insertion holes and passing through the inking chamber. It is being

[Problem that the invention attempts to solve]

However, according to the above-mentioned conventional ink pot, the partition wall and the outer end wall are each formed into a simple flat plate shape,
Since the thread insertion hole is simply formed in this flat plate, there is a problem in that when the ink pot is stood up or tilted, the ink in the ink chamber leaks out from the thread insertion hole.

Furthermore, if a slight gap is created between the thread and the ink cotton due to the thread repeatedly moving back and forth within the ink chamber, there is a risk that the amount of ink ink attached to the thread may be insufficient.

[Means for solving problems]

In order to solve this problem, the ink pot of the present invention has a wall part of the ink chamber case into which the ink juice-permeable material such as ink cotton is inserted, and is recessed in the shape of a funnel toward the inside of the case. A thread insertion hole is provided at the bottom of the recess, and the thread insertion hole on the feeding side has a tapered surface whose inner end facing into the ink chamber gradually becomes larger in diameter toward the ink chamber.

[Effect]

The funnel-shaped recess above looks like this when viewed from inside the ink chamber.
It has a mountain shape with a thread insertion hole at the top, and ink ink is collected at the base of the mountain, which prevents ink from leaking out from the thread insertion hole at the top.

In addition, when the thread passes through the ink chamber and is pulled out from the thread insertion hole on the feeding side, a part of the ink ink-permeable material that is drawn toward the thread insertion hole due to friction with the thread is caused by the tapered surface of the thread insertion hole. Since it is squeezed by the inner end, the ink ink-permeable material reliably contacts the thread and ink ink adheres to it.

〔Example〕

Hereinafter, one embodiment of the ink pot of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2 showing the entire ink pot 1, reference numeral 2 indicates a thread winding section formed in a substantially disk shape, 3 indicates an ink chamber section formed in a substantially cylindrical shape, and a thread 4 is indicated by an arrow.

Reference numeral 8 denotes a knob member having a substantially top shape and housed concentrically on the inner peripheral side of the reel 7, and between the cylindrical shaft portion 8a and the inner peripheral wall of the reel 7, both 7, A spiral spring 9 having one end (an inner end and an outer end) fixed to the spring 8a is interposed.
The reel 7 and the grip member 8 are rotatably inserted into the cases 5 and 6, respectively, and the interposition of the spiral spring 9 allows them to operate in a related manner. The outer end surface of the knob member 8 is exposed to the outside through the circular window 5a of the other case 5. Further, a ratchet gear 10 as shown in FIG. 4 is formed along the circumferential direction on the outer circumferential surface of the knob member 8. A locking pawl 12 projecting obliquely from the inner circumferential surface of the annular ratchet member 11 is elastically engaged, and rotates clockwise in the figure (direction in which the thread 4 is pulled out).
A ratchet mechanism is constructed which rotates in cooperation with the thread 4 and freely rotates counterclockwise (in the winding direction of the thread 4). This ratchet member 11 is free with respect to the reel 7, and has a locking protrusion 13 on its upper end surface.
is integrally installed. Reference numeral 14 denotes a clutch lever member which has an oval annular shape (see FIGS. 5 and 6), is attached to the knob member 8 in a loosely fitted manner, and is connected to the peripheral edge of the circular window 5a of the case 5. The knob member 8 is sandwiched between the circumferential stepped portions 8b with the major diameter direction facing the longitudinal direction of the ink pot 1 so as to be slidable in the same direction. On the lower end surface of the clutch lever member 14, two locking protrusions 15 and 16, one each, are integrally provided on both long diameter ends, and
On the other hand (the right end in the figure), there is a lever 17 on the long diameter end.
A protrusion 18 for fitting a coil spring is integrally provided, and the protrusion 18 and the flange 5b of the case 5
In a normal state (when not in operation), a coil spring 19 installed between the two is elastically biased toward the left in the figure. The slide stroke of the clutch lever member 14 is such that the lever 17
The lever hole 5c of the case 5 into which the clutch lever member 14 is inserted has a length that allows movement, and at the left stroke limit (normal state, non-operation) shown in FIG. The locking protrusion 15 on the side near the lever 17 engages in the circumferential direction, and at the right stroke limit (during operation) shown in FIG. The stop protrusion 16 comes to engage in the circumferential direction.

The ink chamber 3 is made of a cylindrical body 23, and a single-opening door-type lid 24 is provided on a part of the peripheral wall. The end surfaces of the cylindrical body 23 are each recessed in a funnel shape,
Thread insertion holes 26 and 28 are opened at the bottom thereof. Then, the thread insertion hole 26 on the feeding side
The inner end 26a facing the ink chamber 3' has a tapered surface whose diameter gradually increases toward the ink chamber 3', and the other thread insertion hole 28 is also formed in the same shape. FIG. 3 shows the right end surface of the cylindrical body 23 drawn in FIGS. 1 and 2, and the notches 29 for engaging the thread 4 are equally spaced on the periphery of the funnel-shaped recess 25 (8 equally spaced in the figure). ), and a metal ring 30 is fitted into an annular groove 31 provided around the periphery of the notch 29 so as to slightly protrude toward the end surface from the bottom surface of the notch 29 . On the outer periphery of the funnel-shaped recess 27 on the other end surface side of the cylindrical body 23, the case 5 of the thread winding section 2
A connecting portion 32 that is a connecting portion to 6 is formed. That is, the cases 5 and 6 are formed with a cylindrical portion 20 that is a connecting portion corresponding to the connecting portion 32, and the connecting portion 32 is inserted into the cylindrical portion 20. As shown in FIG. 7, two outer circumferential engaging protrusions 33 and 34 are integrally molded at 180 degree symmetrical positions (left and right) on the outer circumferential surface of the cylindrical portion 20, and an eighth As shown in the figure, two inner circumferential engaging protrusions 21 and 22 are also integrally molded at 180 degree symmetrical positions (up and down), and when both 20 and 32 are fitted in the illustrated rotational position, the connecting portion 32 After fitting the outer circumference engagement protrusions 33, 34 into the inner circumference engagement protrusions 21, 22 of the cylindrical portion 20, by relatively rotating them approximately 90 degrees, the engagement protrusions 21, 33, 22 and 34 engage with each other to provide a locking effect, thereby forming a one-touch connection structure that can be freely attached and detached. 3
Reference numeral 5 designates a protective ring having a C-shaped end surface to strengthen and protect the connecting portion. Further, a pin 36 is provided protruding from the end surface of the cylindrical body 23 on the side of the connecting portion 32, as shown in FIGS. 7 and 9. This pin 3
6 is inserted into the cases 5 and 6 and comes into pressure contact with the side wall of the reel 7 when the cylindrical portion 20 and the connecting portion 32 are connected and rotated, as shown in FIG. It constitutes a kind of brake mechanism for Reference numeral 37 is a rubber ring that is fitted onto the cylindrical body 23 when the lid is closed, and acts as a kind of cushion material.

The ink pot 1 having the above structure accommodates ink cotton or sponge (not shown) soaked with ink ink in the cylindrical body 23, and also inserts the thread 4 wound around the reel 7 through the thread insertion holes 28, 26. It is designed so that it can be pulled out in the direction of arrow A. During this drawing process, a part of the ink ink permeable material made of ink cotton or sponge is drawn into the thread insertion hole 26 side by friction with the thread 4 moving in the direction A in the ink chamber 3'.
Since it is squeezed by the tapered inner end 26a of the thread insertion hole 26, the India ink permeable material reliably contacts the thread 4 and adheres ink. Therefore, clear marking lines can be obtained during marking work. Further, the ink pot 1 operates as follows.

(When pulling out the thread 4) When the thread 4 is pulled out and the reel 7 is rotated in the drawing direction (hereinafter referred to as clockwise, as described above), the spiral spring 9 fixed to the reel 7 and the knob member 8 tries to rotate as a result of this. However, the knob member 8 and the ratchet member 11 are configured to co-rotate clockwise by a ratchet mechanism, and the locking projection 13 of the ratchet member 11 and the locking projection 15 of one of the clutch lever members 14 are rotated in the circumferential direction. Since the grip member 8 is engaged with the ratchet member 14 to prevent the clockwise rotation of the ratchet member 14 (Fig. 5), the grip member 8 does not rotate and functions similarly to the core rod in conventional products, tightening the spiral spring 9. It becomes like this.

(When the release mechanism is activated) When the thread 4 is pulled out to a certain extent, the spiral spring 9
is tightened to the limit and the reel 7 stops rotating, making it impossible to pull out the thread 4 any further.

In this state, pull the lever 17 of the clutch lever member 14 to
When the engagement between the locking protrusion 15 on one side and the locking protrusion 13 on the ratchet member 11 is released, the latch member 11 and the knob member 8 begin to turn vigorously clockwise due to the elastic restoring force of the spiral spring 9, turning half a turn. By the way, the locking protrusion 13 of the ratchet member 11 collides with the other locking protrusion 16 of the clutch lever member 14, and its rotation is stopped (FIG. 6).
When the lever 17 is returned, the engagement is released and the ratchet member 11 and the knob member 8 rotate half a circle again until the locking projection 13 of the ratchet member 11 comes into contact with the original locking projection 15. It becomes like this. In other words, when the lever 17 is pulled, the knob member 8 rotates halfway around.
When the lever 17 is returned, it rotates clockwise half a turn, loosening the spiral spring 9 by the amount of rotation. After this operation, the lever 17 is tightened again by the amount that the spiral spring 9 has been loosened. Pull out the extra thread 4.

(When storing the thread 4) When the force that was pulling out the thread 4 against the elastic return force of the spiral spring 9 is removed, the reel 7 automatically moves the thread 4 in the winding direction (counterclockwise) due to the elastic return force. ) to wind and store the thread 4.
At this time, the knob member 8 tries to rotate clockwise due to the same elastic return force, but as described above, this movement is prevented by the engagement of the knob member 8, the ratchet member 11, and the clutch lever member 14. , the knob member 8 does not rotate. When the spiral spring 9 returns to the free state and the rotation of the reel 7 comes to a natural stop, the yarn 4 that has been excessively pulled out by the release mechanism remains as it is without being wound around the reel 7. Therefore, grasp the gripping portion 7a of the reel 7 and manually release the reel 7.
is rotated in the winding direction, and the remaining part of the thread 4 is wound and stored. At this time, the knob member 8 connected to the reel 7 via the spiral spring 9 tries to rotate in the same direction, but the counterclockwise rotation is
Since the ratchet mechanism is free from the ratchet member 11 in the direction of engagement, it can be rotated as it is without any hindrance.

After storing all of the thread 4, hold down the grip part 7a of the reel 7 and pull the lever 17,
Manually rotate the knob member 8 to the left several times, and then return the lever 17. As a result, the spiral spring 9 is kept in a slightly tightened state, so that even if the thread 4 is pulled out a little in the next operation,
The elastic return force of the spring 9 increases, making it easier to unwind the thread 4.

Next, how to use the ink pot 1 will be explained. When using a conventional ink pot, the operator tied a thread to the end of the thread and fixed it at the desired location, pulled out the thread, and pressed it with his or her fingers to ink the thread. On the other hand, the inking pot 1 is designed to save the effort of pressing the thread 4, and as shown in FIG. The thread 4 is pulled out from a notch 29 provided on the end surface of the metal ring 30 as if it were sliding on the metal ring 30. Further, on both end surfaces of the cylindrical body 23 of the ink chamber 3,
Since the funnel-shaped recesses 25 and 27 are provided, the ink inside the cylindrical body 23 is difficult to flow outside or into the thread winding part 2 during use or during transportation. The connection between the cylindrical part 20 and the connecting part 32 between the cases 5 and 6 and the cylindrical body 23 is achieved by the engagement of the engaging protrusions 21, 33, 22, and 34 without using special connecting parts such as bolts, nuts, and screws. Since it is only necessary to attach and detach, both the structure and the attachment/detachment operation are extremely simple.

[Effect of idea]

As explained above, in the ink pot of the present invention, the wall of the ink chamber case into which the ink ink permeable material such as ink cotton is inserted is recessed in a funnel shape toward the inside of the case, and the funnel-shaped recess is recessed. Since the thread insertion hole is formed at the bottom, it is possible to prevent ink ink from leaking out of the ink chamber without the need for a special sealing material.

Moreover, when the thread is pulled out, a part of the ink ink-permeable material that is drawn toward the thread insertion hole on the drawing-out side due to friction with the thread is squeezed by the tapered inner end of the thread insertion hole. , since it makes sure contact with the thread and adheres the ink ink, it has excellent effects such as being able to create clear ink lines.
