Description

  The present invention relates to a nail interval adjusting tool used for adjusting an opening / closing interval of two nails placed on a game board surface of a gaming machine such as a pachinko gaming machine or a coin gaming machine.

  A nail that is driven into the surface of a game machine such as a pachinko machine, in particular, an obstacle nail that is placed above the chucker and is called a “life nail” or “navel nail”, is the opening / closing interval of the two nails (nail The so-called nail master adjusts and manages the opening and closing of the ball. There are various adjustment methods depending on the nail artist, but in general, hold a hammer in one hand and a ball gauge or angle gauge in the other hand, and finely adjust the angle while hitting the side of the nail with a hammer. To do.

However, in the method of adjusting the angle by hitting such nails one by one, it is necessary to hit each of the two nails with a hammer, which is troublesome and inefficient. Therefore, as a technique capable of shortening the time required for the interval adjustment, for example, there is “Pachinko game table nail adjustment pliers” disclosed in Patent Document 1.
Japanese Unexamined Patent Publication No. 1-144083

  However, according to such a technique disclosed in Patent Document 1, two nails are sandwiched from both sides at the press contact portion of the pliers to narrow the distance between them, and a gauge member such as a ball gauge is interposed between both nails. In order to prevent the gap between the nails from becoming narrower than that, it is regulated.

  For this reason, since the distance between the nails can be narrowed but cannot be widened, when it is desired to widen the distance, it is necessary to hit each of the two nails with a hammer or the like as in the prior art. That is, since the gap between the nails is not only narrowed, the technique disclosed in Patent Document 1 cannot be applied when it is necessary to widen the gap, and there is a problem that it takes time to adjust the gap. .

  Further, since the gap is narrowed by interposing a gauge member between the nails, the nail bends around the gauge member as a fulcrum. For this reason, since the nail is deformed into a “heavy” shape from the middle of the upper part of the base of the game board surface, when trying to widen the gap between the deformed and narrowed nails, “S-shaped” There is a problem that the nail is deformed (meandering deformation) as if it is meandering in shape, and the appearance is deteriorated.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a nail interval adjusting tool that can shorten the nail interval adjusting time and can prevent the meandering deformation of the nail.

In order to achieve the above object, the means described in claim 1 described in claims is adopted. According to this means, the tool tip portion is provided with two plate walls each having a groove width wider than the axial diameter of the nail and extending in the longitudinal direction of the tool tip portion in a substantially parallel manner at a predetermined interval. Two of them are formed side by side in the upward or downward direction with respect to the virtual surface that expands in the opening / closing direction of the distal end portion, and these plate walls are not formed and project in a plate shape along the virtual surface toward the distal end side. At each tip, a flat portion that is linear in the direction in which the virtual plane expands is formed at a contact portion with the game board surface so as to be orthogonal to the groove, and both the groove portions are opened and closed with the opening and closing of the tool tip. with spacing is wide or narrow, this interval, both the groove and equal to the base distance between the two nails become substantially parallel, the both end portions and the unequal is not parallel.

As a result, by fitting two nails (having the root interval set to a predetermined value in advance) placed on the gaming board surface of the gaming machine into the two grooves, respectively, Since these nails are respectively hooked in the groove portions in the opening / closing direction, the opening / closing intervals of the two nails can be adjusted in the opening direction and the closing direction by opening / closing the tool tip portion by the pliers structure. Further, the two groove portions are formed to extend in the longitudinal direction of the tool tip portion by two plate walls erected substantially parallel to each other at a predetermined interval, and the interval between the two groove portions is the two grooves. When it becomes equal to the root distance of the nail, it becomes almost parallel, and when it is not equal, it becomes non-parallel. Can do. In addition, in the direction in which the imaginary plane expands at the abutting portion with the game board surface so as to be orthogonal to the groove portions at the respective leading ends projecting in a plate shape along the virtual plane without forming these plate walls. A flat portion having a linear shape is formed.

The means described in claim 2 described in claims is adopted. According to this means, the length of the plate wall is set to 0.5 to 0.8 times the axial length of the nail exposed from the game board surface, and the two groove portions formed by these plate walls Are formed from one end side to the other end side of the plate wall at a predetermined angle set to a predetermined acute angle with respect to the virtual plane. Thus, with respect to the nail that is substantially perpendicular Da設the game board of the gaming machine, since the tool tip upward or downward at a constant angular degree can be aligned, setting the angle of this Thus, it is possible to make it difficult to place a physical burden on the wrist and arm of the nail artist (user of the tool).

The means described in claim 3 described in claims is adopted. According to this means, the constant angle is not less than 10 degrees and not more than 30 degrees. As a result, when a standard adult nail master sits on a chair installed in front of a gaming machine and works, it is possible to confront almost the entire nail on the game board surface with a good positional relationship. It can make it difficult to put a physical burden on the wrist and arm.

  The means described in claim 4 described in the claims is adopted. According to this means, the tool tip is formed with a notch that extends in the longitudinal direction and is wide and capable of communicating with the groove and accommodating the nail head of the nail. As a result, the nail head can move in the longitudinal direction of the tool tip in such a notch, so that the nail shaft portion of the nail fitted in the groove can also be moved in the longitudinal direction of the tool tip. That is, since the nail fitted in the groove can be slid in the longitudinal direction of the tool tip, the position of the groove relative to the nail can be changed, or the shape of the nail can be adjusted by pressing the nail.

  The means described in claim 5 described in claims is adopted. According to this means, when the grip portion is closed, the interval between the tool tip portions is widened, and when the grip portion is opened, the tool tip portion is narrowed. Because of the characteristics of a human hand that can generally exert power rather than opening the hand, the invention according to claim 1 is a tool that focuses on the method of closing (narrowing) the opening / closing interval of the nail. For example, the invention according to claim 5 can provide a tool that focuses on a method of opening (expanding) the opening / closing interval of the nail. Moreover, it becomes possible to apply each feature of Claims 2-4 to what opens and closes a space | interval.

In the invention of claim 1, by fitting two nails (having the root interval set to a predetermined value in advance) placed on the gaming board surface of the gaming machine into the two groove portions, Since these nails are hooked in the grooves with respect to the opening and closing direction of the tool tip, the opening and closing intervals of the two nails can be adjusted in the opening and closing directions by opening and closing the tool tip with a pliers structure. Can do. Therefore, since the opening / closing interval of the nail can be narrowed or expanded with the same tool, the nail interval adjusting time can be shortened. Further, the two groove portions are formed to extend in the longitudinal direction of the tool tip portion by two plate walls erected substantially parallel to each other at a predetermined interval, and the interval between the two groove portions is the two grooves. When it becomes equal to the root distance of the nail, it becomes almost parallel, and when it is not equal, it becomes non-parallel, so it can be deformed in the same groove part in the closing direction and the opening direction with respect to the nail, and also deformed in the same position with respect to the nail Can do. Therefore, since the deformation position of the nail is fixed in both the closing direction and the opening direction, meandering deformation of the nail can be prevented. In addition, in the direction in which the imaginary plane expands at the abutting portion with the game board surface so as to be orthogonal to the groove portions at the respective leading ends projecting in a plate shape along the virtual plane without forming these plate walls. A flat portion having a linear shape is formed. Therefore, the tip of the tool tip can be applied almost perpendicularly to the game board surface.

In the invention of claim 2, with respect to the nail that is substantially perpendicular Da設the game board of the gaming machine, since the tool tip at a constant angular degrees upward or downward can be aligned, this By setting the angle, it is possible to make it difficult to place a physical burden on the wrist and arm of the nail artist (user of the tool). Therefore, since it becomes difficult to get tired even if it is used for a long time, it is possible to shorten the time for adjusting the nail interval and to improve the working efficiency.

  According to the third aspect of the present invention, when a standard adult nail master sits on a chair installed in front of a gaming machine and works, it becomes possible to confront almost the entire nail on the game board surface with a good positional relationship. , It can make it difficult to put a physical burden on the wrist and arm of the nails. Therefore, since it becomes difficult to get tired even if it is used for a long time, it is possible to shorten the time for adjusting the nail interval and to improve the working efficiency.

  In the invention of claim 4, as a result of the nail head being movable in the longitudinal direction of the tool tip within such a notch, the nail shaft of the nail fitted in the groove is also moved in the longitudinal direction of the tool tip. be able to. That is, since the nail fitted in the groove can be slid in the longitudinal direction of the tool tip, the position of the groove relative to the nail can be changed, or the shape of the nail can be adjusted by pressing the nail. Therefore, it is possible to change the position where the nail is deformed or to arrange the nail that has been deformed unintentionally.

  According to the fifth aspect of the present invention, it is possible to provide a tool that focuses on the method of opening (expanding) the opening / closing interval of the nail. Therefore, the nail interval adjustment time can be shortened with respect to the opening direction of the opening / closing interval, and the meandering deformation of the nail can be prevented. In addition, since it is possible to make it difficult to place a physical burden on the wrist and arm of the nail artist, work efficiency can also be improved. Even in the invention according to claim 5, like the invention according to claim 1, the nail interval adjustment time can be shortened with respect to the “opening” direction of the open / close interval, and the nail meandering Deformation can also be prevented.

  Hereinafter, an embodiment of a nail interval adjusting tool of the present invention will be described with reference to the drawings. The nail interval adjusting tool 10 according to the present embodiment is used for adjusting the opening / closing interval of two nails placed on a game board surface of a gaming machine such as a pachinko gaming machine or a coin gaming machine. It is an effective tool for adjusting the opening and closing intervals of obstacle nails (opening and closing states of obstacle nails) called “nails” and “navel nails”.

  First, the configuration of the nail interval adjusting tool 10 will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing the overall configuration of the nail interval adjusting tool 10, which is viewed from the back side during normal use (see FIG. 3). FIG. 2 shows the configuration of the tool tip 20 and the like.

  As shown in FIG. 1, the nail interval adjusting tool 10 according to the present embodiment is mainly composed of grip portions 11 and 12 and movable portions 14 and 15, and is formed integrally and has a rod-like grip portion. 11 and the movable part 14, and the grip part 12 and the movable part 15, which are similarly rod-shaped, are crossed, and the crossing part is pivotally supported by the shaft part 16.

  Thereby, in the said nail space | interval adjustment tool 10, when the grip parts 11 and 12 are closed, the space | interval of the edge part 14a of the movable part 14 and the edge part 15a of the movable part 15 becomes narrow, and when the grip parts 11 and 12 are opened, it is movable. The movable portions 14 and 15 operate like a Western-style rice cake in which the distance between the end portion 14a of the portion 14 and the end portion 15a of the movable portion 15 is widened. That is, the nail interval adjusting tool 10 is configured to have a “pinch structure that closes when nipped” (or pliers structure).

  In addition, the nail | interval space | interval adjustment tool 10 of this embodiment is provided with the spring 18 as a compression coil spring which spreads against the pushing force between the grip parts 11 and 12 close to the shaft part 16. As a result, the biasing force (repulsive force) of the spring 18 biases the grips 11 and 12 in the direction in which the distance between the grips 11 and 12 increases, so that when the user is not gripped by the nail spacing adjusting tool 10 (for example, a nail artist). The nail interval adjusting tool 10 keeps the grips 11 and 12 in an open state.

  FIG. 1 shows a closing direction (arrows with broken lines) of the movable parts 14 and 15 that are opened and closed by such a “hold and close type” pliers structure, and a symbol K indicating a virtual plane extending in the opening and closing direction. In addition, a center line J that passes through the shaft portion 16 that is the center of the open / close range of the movable portions 14 and 15 on the virtual plane K is indicated by a one-dot chain line J.

  The nail interval adjusting tool 10 according to the present embodiment includes end portions 14a and 15a (hereinafter collectively referred to as “base 21”) of movable portions 14 and 15 (hereinafter collectively referred to as “tool tip portion 20”) that open and close in this manner. Characteristic in shape. For this reason, from here, the tool front-end | tip part 20 is demonstrated mainly with reference to FIG. In addition, since the shape of each base 21 which comprises the tool front-end | tip part 20 is comprised similarly about both the edge part 14a and the edge part 15a, it demonstrates on behalf of the edge part 14a here.

  2A is a plan view of the tool tip 20, FIG. 2B is a side view of the tool tip 20 viewed from the 2B direction shown in FIG. 2A, and FIG. 2) is a bottom view of the tool tip 20 seen from the 2C direction shown in FIG. 2B, and FIG. 2D is a front view of the tool tip 20 seen from the 2D direction shown in FIG. 2B. FIG. 2 (E) shows the configuration of the obstacle nail 110 placed on the game board 100. FIG.

  In the tool tip 20, a groove 23 extending in the longitudinal direction of the tool tip 20 with a groove width wider than the shaft diameter X of the obstacle nail 110 is formed on each base with respect to a virtual plane K extending in the opening / closing direction of the tool tip 20. 21 are formed side by side in the downward direction (see FIG. 1).

  That is, as shown in FIGS. 2 (B) to 2 (D), the groove portion 23 is provided with two guides 22 erected substantially parallel to each base 21 at a predetermined interval α in a plate wall shape. The position interval between the two groove portions 23 increases or decreases with the opening and closing of the tool tip portion 20. Further, as will be described later, these groove portions 23 are positioned so as to be substantially parallel when the interval between both groove portions 23 becomes equal to the root interval of the obstacle nail 110.

  The two guides 22 forming such a groove 23 have a predetermined interval (groove width) α set to, for example, 1.2 to 1.5 times the shaft diameter X of the obstacle nail 110. If this interval is smaller than 1.2 times the shaft diameter X, it becomes difficult to fit the obstacle nail 110 between the guides 22, that is, the groove 23. Since the play space of the nail 110 is created and the obstacle nail 110 cannot be bent at the intended position, the groove width α of the groove 23 is set in this way. The shaft diameter X of the obstacle nail 110 here means the thickness of the nail shaft portion 110a as shown in FIG. 2 (E), and is usually set to 1.7 mm.

  In this embodiment, as shown in FIG. 2B, the groove portion 23 is formed with an angle θ with respect to the base 21. That is, the groove 23 is relative to the above-described virtual plane K (a plane extending in the opening / closing direction of the tool tip 20 and including the line K shown in FIGS. 2B and 2D in FIG. 2). A predetermined acute angle is formed along the angle θ direction. For example, the angle θ is set in the range of 10 degrees to 30 degrees (for example, 15 degrees), and a standard adult body user (nails) is installed in front of a gaming machine (usually a game When sitting on a chair on which a machine customer sits, the work can be done with a good positional relationship with respect to almost the entire nail of the game board surface.

  As shown in FIG. 2C, the length (groove length) β of these two guides 22 is set to 0.5 to 0.8 times the axial length Y of the obstacle nail 110, for example. . Further, the length β ′ from the front end (hereinafter referred to as “base front end”) 21 a of the base 21 to the guide rear end 22 b is set to be at least shorter than the axial length Y of the obstacle nail 110. That is, the nail head portion 110b of the obstacle nail 110 is set so as to protrude from the groove portion 23 to a notch portion 25 described later. In addition, the axial length Y of the obstacle nail 110 here means the length including the nail shaft part 110a and the nail head part 110b exposed from the board surface 100a as shown in FIG. 2 (E). Usually, it is set to 17 mm. The total length of the obstacle nail 110 is usually 33 mm.

  In the present embodiment, as shown in FIG. 2B, the tip 22 of the guide 22 (hereinafter referred to as “guide tip”) 22a and the tip of the base 21 (hereinafter referred to as “base tip”) 21a are rounded. Yes. That is, by taking the corners of the guide tip 22a and the base tip 21a (chamfering), as will be described later, even when the nail spacing adjusting tool 10 is in contact with the board surface 100a of the game board 100, the board surface 100a is not affected. I am trying not to get scratches.

  As shown in FIGS. 2A and 2B, the flat portion side (the shaded portion shown in FIGS. 2A and 2B) where the guide 22 of the base 21 is not formed is also in the width direction. Both corners 21b are rounded. This chamfering is also made so that the board surface 100a is not easily scratched even if it contacts when the nail interval adjusting tool 10 is used.

  As shown in FIGS. 2B and 2C, the base 21 has a notch 25 in addition to the guide 22. The notch 25 is formed on the side of the base 21 where the guide 22 is formed (in the present embodiment, the lower side) so as to communicate with the groove 23 described above. The notch 25 is for accommodating the nail head 110 b of the obstacle nail 110 fitted in the groove 23. For this reason, the notch length γ is set so that the nail head portion 110 b of the obstacle nail 110 does not contact the rear end wall 21 c of the base 21.

  In the present embodiment, the base tip 21a of the base 21 protrudes from the guide tip 22a of the guide 22, and the end of the base tip 21a is formed flat. That is, as shown in FIG. 2C, the base 21 protrudes such that its flat tip extends in the tip direction from the guide 22 by (β′−β). Thus, as will be described later, when the base tip 21a comes into contact with the board surface 100a of the game board 100 when the nail interval adjusting tool 10 is used, the base 21 is guided so as to be substantially perpendicular to the board surface 100a. I am doing.

  For example, the base tip 21a and the guide tip 22a may be covered with an object (elastic body) softer than the board surface 100a such as rubber or resin. Thereby, since such an elastic body plays the role of a buffer member, it is possible to prevent the board surface 100a from being damaged even if the base tip 21a or the like contacts the board surface 100a.

  Thus, the nail | interval space | interval adjustment tool 10 with which the tool front-end | tip part 20 is comprised is used as shown in FIG.3 and FIG.4, for example. FIG. 3 shows a state in which a user (for example, a nail artist) adjusts the opening / closing state of the obstacle nail 110 using the nail interval adjusting tool 10, and FIG. The state which looked up at the tool front-end | tip part 20 of the nail space | interval adjustment tool 10 shown in FIG. Reference numerals 120 and 130 both indicate “chucker”.

  That is, as shown in FIG. 3, with the guide 22 and the groove 23 facing downward (in the direction of gravity) with the nail interval adjusting tool 10 placed, grasp the grips 11 and 12 so that they are covered with palms from above. The nail interval adjusting tool 10 is grasped.

  Then, as shown in FIG. 4, aiming at the nail root 110c of the two obstacle nails 110 to be adjusted for opening and closing, the base tip 21a is aligned so as to be in perfect contact with the board surface 100a, and then the obstacle nail is The nail shaft 110a is fitted into the groove 23 between the guides 22 so as to cover the base 21 from above the nail shaft 110a. At this time, the base 21 is positioned so that the nail head 110 b of the obstacle nail 110 protrudes from the groove 23 and the nail head 110 b enters the notch 25.

  In this state, when the grip portions 11 and 12 are gripped so as to close the space between the grip portion 11 and the grip portion 12, the distance between the end portion 14a of the movable portion 14 and the end portion 15a of the movable portion 15 is narrow. That is, since the space between both bases 21 is narrowed, the opening / closing interval between the obstacle nails 110 that are fitted and hooked in the groove portions 23 of both bases 21 is narrowed. As a result, the opening / closing interval of the obstacle nail 110 is reduced in the closing direction. Can be adjusted.

  On the contrary, when the grips 11 and 12 are opened so that the gap between the grip 11 and the grip 12 is opened, the space between the bases 21 is widened. The opening / closing interval between the obstacle nails 110 that have been stopped is widened, and the opening / closing interval of the obstacle nail 110 can be adjusted in the opening direction.

When the operation of the tool tip 20 is arranged, it is expressed as shown in FIG.
That is, as shown in FIG. 5A, the tool tip 20 has a groove 23 extending in the longitudinal direction of the tool tip 20 with a groove width α wider than the shaft diameter X of the obstacle nail 110. Are formed side by side in a downward direction with respect to a virtual plane K extending in the opening / closing direction (see FIG. 2), and the gap Z1 between the groove portions 23 becomes wider and narrower as the tool tip 20 is opened and closed. When the distance Z1 is equal to the root distance Z0 of the two obstacle nails 110, both the groove portions 23 become substantially parallel.

  As a result, the two obstacle nails 110 placed on the board surface 100a of the game board 100 are fitted into the two groove portions 23, respectively, so that these obstacle nails are in the opening / closing direction of the tool tip portion 20. 110 is hooked in the groove 23, and the opening / closing interval Z1 is adjusted in the opening direction and the closing direction by changing the inclination angle Zθ of the two obstacle nails 110 by opening and closing the tool tip 20 by the pliers structure. Can do.

  For example, as shown in FIG. 5 (C), when the grips 11 and 12 are gripped so that the gap between the bases 21 is narrowed, the obstacle that has been hooked in the groove 23 of both the bases 21 is locked. The inclination angle Zθ of the nail 110 is an acute angle. As a result, the opening / closing interval Z2 between the groove portions 23 becomes narrower than the root interval Z0, so that the opening / closing interval Z2 of the obstacle nail 110 can be adjusted in the closing direction.

  On the other hand, as shown in FIG. 5 (D), when the grips 11 and 12 are opened, the distance between the bases 21 is widened, so that the obstacle nail 110 fitted in the groove 23 of both the bases 21 is hooked. The inclination angle Zθ is an obtuse angle. As a result, the opening / closing interval Z3 between the grooves 23 is larger than the root interval Z0, so that the opening / closing interval Z3 of the obstacle nail 110 can be adjusted in the opening direction.

  Further, as shown in FIG. 5A, these two groove portions 23 are formed extending in the longitudinal direction of the tool tip portion 20, and the interval between the two groove portions 23 is the distance between the two obstacle nails 110. When equal to the root interval Z0, both groove portions 23 are substantially parallel (parallel to the central axis J). For this reason, the closing direction and the opening direction with respect to the obstacle nail 110 can be deformed by the same groove 23, and the obstacle nail 110 can be deformed at the same position. Accordingly, since the deformation position of the obstacle nail 110 is fixed in both the closing direction and the opening direction, meandering deformation of the obstacle nail 110 can be prevented.

  Further, as shown in FIG. 5B, the two groove portions 23 formed in each base 21 are formed along a direction that forms a predetermined acute angle θ with respect to the virtual plane K. As a result, the tool tip 20 is placed at a predetermined angle θ upward (antigravity direction) or downward (gravity direction) with respect to the obstacle nail 110 that is driven almost perpendicularly to the board surface 100a of the game board 100. Can be aligned.

  For example, by setting this angle θ to 10 degrees or more and 30 degrees or less, when a standard adult user (for example, a nail artist) sits on a chair installed in front of the game board 100 and works, Since it is possible to confront the almost entire obstacle nail 110 on the board surface 100a with a good positional relationship, it is possible to make it difficult to apply a physical burden to the wrist and arm of the user. Therefore, since it becomes difficult to get tired even if it is used for a long time, in addition to shortening the interval adjustment time of the obstacle nail 110, work efficiency can be improved.

  Furthermore, as shown in FIGS. 5 (C) and 5 (D), the tool tip 20 has a wide and longitudinally extending notch that communicates with the groove 23 and can accommodate the nail head 110b of the obstacle nail 110. A portion 25 is formed. As a result, the nail head portion 110b can move in the longitudinal direction of the tool tip portion 20 in such a cutout portion 25. As a result, the nail head portion 110b of the obstacle nail 110 fitted in the groove portion 23 is also the tool tip portion 20 in the same manner. Can be moved in the longitudinal direction (arrow directions shown in FIGS. 5C and 5D).

  That is, since the obstacle nail 110 fitted in the groove 23 can be slid in the longitudinal direction of the tool tip 20, the position of the groove 23 with respect to the obstacle nail 110 can be changed, or the obstacle nail 110 can be shaped by the groove 23. It becomes possible to arrange. Therefore, the position where the obstacle nail 110 is deformed can be changed, or an unintentionally deformed nail can be prepared.

  The nail interval adjusting tool 10 described above is configured to have a “pinch structure that closes when gripped” (or a plier structure), but conversely, a “pinch structure that opens when gripped” (or (A plier structure). That is, as shown in FIG. 6, when the grip portions 11 and 12 are closed, the distance between the end portion 14a ′ of the movable portion 14 ′ and the end portion 15a ′ of the movable portion 15 ′ is widened (arrow by the broken line). 11 and 12, the nail interval adjusting tool 10 ′ in which the movable portions 14 ′ and 15 ′ operate so that the distance between the end portion 14 a ′ of the movable portion 14 ′ and the end portion 15 a ′ of the movable portion 15 ′ becomes narrower. Also, the present invention can be applied.

  As a result, in the above-described nail interval adjusting tool 10, gripping is generally more effective than opening the hand. Due to the characteristics of a human hand, emphasis is placed on closing (narrowing) the opening / closing interval of the obstacle nail 110. In contrast to the placed tool, the nail interval adjusting tool 10 ′ shown in FIG. 6 is a tool that places emphasis on how to open (expand) the open / close interval of the obstacle nail 110.

  That is, the interval adjustment time can be shortened with respect to the opening direction of the opening / closing interval of the obstacle nail 110, and the meandering deformation of the obstacle nail 110 can be prevented. Further, similarly to the nail interval adjusting tool 10, it is possible to make it difficult to put a physical burden on the wrist and arm of the user (for example, a nail maker), so that the work efficiency can be improved and the obstacle nail 110 can be improved. Serpentine deformation can also be prevented.

  In the embodiment described above, both the groove portions 23 are formed in the tool tip portion 20 side by side with respect to the imaginary plane K in the downward direction of the respective bases 21. You may form in a direction. In this case, with the nail interval adjusting tool placed with the guide 22 and the groove 23 facing upward (anti-gravity direction), the nail interval adjusting tool 10 is grasped by grasping the grip portions 11 and 12 so as to cover with palms from above. The nail shaft 110a is fitted into the groove 23 so that the base 21 is covered from below the obstacle nail 110. Others can be used in the same manner as the nail interval adjusting tool 10 in the positional relationship upside down in each figure shown in FIG.

  Further, such both groove portions 23 may be formed side by side with respect to the virtual plane K in both the upper and lower directions of the respective bases 21. As a result, it becomes possible to fit the nail shaft portion 110a into the groove portion 23 so that the base 21 can be covered with the obstacle nail 110 from either the upper or lower direction, and the usability can be further improved.

  In the embodiment described above, the configuration and usage example of the nail interval adjusting tool 10 have been described by exemplifying a case where the opening / closing state of the obstacle nail 110 placed on the board surface 100a of the game board 100 is adjusted. The application of the nail interval adjusting tool according to the present invention is not limited to this, for example, the interval adjustment of each nail (top nail, road nail, step nail, step nail, jump nail) placed in a gaming machine, The present invention can also be applied to a tool for finely adjusting the opening / closing interval of two nails driven so that the nail shaft portion is exposed on the wall surface of a building.

  Further, in the embodiment described above, the tool tip portion 20 is integrally formed with the grip portions 11 and 12 as a part of the movable portions 14 and 15, but the tool tip portion as an attachment removable to the movable portion tip of the general-purpose tool. 20 (base 21) may be configured separately. Thereby, this invention is applicable to the general purpose tool which can replace | exchange the movable part front-end | tip for various attachments.

  For example, if this is grasped as a creation of a technical idea, “a pliers structure (or a plier structure) in which the gap between the movable part tips becomes narrower when the grip part is closed, and the gap between the movable part tips becomes wider when the grip part is opened. Alternatively, when the grip portion is opened, the interval between the movable portion tips becomes narrower, and when the grip portion is closed, the interval between the movable portion tips becomes wider. A tool attachment comprising a set of two rod-shaped sets provided, wherein a groove extending in the longitudinal direction is formed with a groove width wider than the axial diameter of a nail placed on the gaming board surface of the gaming machine, and the movable When attached to the tip of the part, the tool attachment is characterized in that two of the groove parts are arranged side by side in the upward or downward direction with respect to a virtual surface that expands in the opening / closing direction of the tip of the movable part.

  Specifically, for example, it is configured as shown in FIG. 7A is a side view of the tool attachment 50, FIG. 7B is a bottom view of the tool attachment 50 viewed from the 7B direction shown in FIG. 7A, and FIG. A cross-sectional view of the cross section taken along the alternate long and short dash line shown in FIG.

  That is, each component (guide 22, groove 23, etc.) of the base 21 of the tool tip 20 as described above is formed on one end of the tool attachment 50, and a general-purpose tool (not shown) is movable on the other end. A detachable round bar-like connection part 52 is formed at the tip of the part. The connection portion 52 is formed with a notch groove 54 in a part thereof. As a result, the position around the axis of the tool attachment 50 is unambiguous, that is, it can be attached to the tip of the movable part of the general-purpose tool so that the guide 22 and the groove part 23 face downward (gravity direction) or upward (antigravity direction). Become.

  Note that a connection hole into which the connection part 52 can be inserted is formed at the distal end of the movable part of the general-purpose tool. The connection hole 52 protrudes substantially perpendicular to the connection hole and is inserted into the notch groove 54 of the connection part 52 inserted into the connection hole. An engaging screw is provided. Thereby, the tool attachment 50 can be fixed to a predetermined direction (orientation) at the tip of the movable part.

  With this configuration, the two obstacle nails 110 (nails) placed on the gaming board 100 (the gaming board surface of the gaming machine) are respectively inserted into the groove portions 23 of such a set of two tool attachments 50. By fitting, the obstacle nails 110 are hooked in the groove portions 23 in the opening / closing direction of the distal end of the movable portion. For this reason, the opening and closing intervals of the two obstacle nails 110 can be adjusted in the opening direction and the closing direction by opening and closing the tip of the movable part by the pliers structure.

  In addition, when the distance between the two groove portions of such a set of two tool attachments 50 is equal to the root interval of the two obstacle nails 110, the tool attachment 50 is made to be substantially parallel to the movable part of the general-purpose tool. By attaching to the tip, the closing direction and the opening direction of the obstacle nail 110 can be deformed at the same groove, and the obstacle nail 110 can be deformed at the same position.

  Furthermore, by forming the two groove portions 23 provided in such a set of two tool attachments 50 along a direction that forms a predetermined acute angle θ with respect to the virtual plane K, the game board 100 is substantially The tool attachment 50 can be aligned at a predetermined angle θ (acute angle) upward or downward with respect to the obstacle nail 110 that is vertically driven. Thereby, it is possible to make it difficult to apply a physical burden to the wrist and arm of the nail master (user of the general-purpose tool with the tool attachment attached) by setting the predetermined angle θ.

  Furthermore, by setting the angle θ of the “predetermined acute angle” to 10 degrees or more and 30 degrees or less, a standard adult body nailman sits on a chair installed in front of a game machine and works. Then, it becomes possible to confront almost the entire nail of the game board 100 with just a good positional relationship, so that it is difficult to apply a physical burden to the wrist and arm of the nail master.

  Further, such a set of two tool attachments 50 is formed with a notch 25 extending in the longitudinal direction and extending in the longitudinal direction so as to communicate with the groove 23 and accommodate the nail head 110b of the nail. However, as a result of being able to move in the longitudinal direction of the tool attachment 50 within the notch 25, the nail shaft 110a of the obstacle nail 110 fitted in the groove 23 can be moved in the longitudinal direction of the tool attachment 50 as well. . That is, since the obstacle nail 110 fitted in the groove 23 can be slid in the longitudinal direction of the tool attachment 50, the position of the groove 23 with respect to the obstacle nail 110 is changed or the shape of the obstacle nail 110 is adjusted by the groove 23. It becomes possible.
