Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gauge for adjusting a nail of a pachinko machine or the like, and in particular, can easily and accurately adjust an interval between obstacle nails called life nails (hereinafter referred to as life nails) that influence the winning of a pachinko ball. The present invention relates to a nail adjustment gauge such as a pachinko machine.
[0002]
[Prior art]
A lot of various winning holes are arranged on the game board surface of a pachinko machine or the like, and whether or not a pachinko ball wins each winning hole greatly depends on the adjustment of the life nail. In the adjustment of such a life nail, a gauge having a gauge ball attached to one or both ends of the grip handle is used, and the gauge ball at the tip of the gauge is passed between the life nails, so that the widest width of the gauge ball is obtained. It is common to adjust the interval of the life nail while checking the condition of the portion (diameter width of the gauge ball). And the adjustment of the life nail by such a conventional gauge is performed by predicting the position where the pachinko ball will flow down the game board and pass between the life nail, relying on experience and feeling, to the position that seems to be most appropriate Since the ball was adjusted together, it required considerable skill to adjust accurately. Therefore, for those who are not skilled in adjusting the nail, a means for adjusting the nail by passing it between the life nails while bringing the gauge ball into contact with the game board so that the nail can be adjusted at a position as constant as possible. Was taken.
[0003]
[Problems to be solved by the invention]
However, if the gauge ball is to be adjusted while abutting against the game board, the passing position of the widest part of the gauge ball will differ depending on the diameter of the gauge ball, so a gauge ball with a different diameter was attached. Each time the gauge is used, the contact part of the gauge ball and the nail changes, and the nail cannot be adjusted based on a certain position, and accurate measurement is impossible with such a method.
[0004]
Therefore, the present invention has been made to solve the above-described problems, and no one has to rely on experience or feeling so that the gauge ball of the gauge is always located at a predetermined position at a certain distance from the game board. The purpose of this is to make it possible to adjust the nail easily and accurately.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a spherical gauge ball fixed to one or both ends of a grip handle, and a protrusion for separating the gauge ball from the game board surface at the tip of the gauge ball. It is a feature.
[0006]
In addition, it is desirable that the tip end surface of the protrusion is formed as a spherical surface having the same center as the center of the gauge sphere. By forming in this way, even if the gauge is inclined with respect to the game board surface, the position of the gauge ball can be kept constant and accurate adjustment can be performed.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a nail adjustment gauge according to the present invention, and FIG. 2 is a plan view thereof. In the nail adjustment gauge shown in FIGS. 1 and 2, gauge balls 2 and 2 are fixed to both ends of the handle 1, and protrusions 3 and 3 are integrally formed at the ends of the gauge balls 2 and 2. It is extended.
[0008]
The grip handle 1 is formed in a round bar shape from a metal material or other material, and display portions 4a, 4b, 5a, 5b for displaying the diameter values of the gauge balls 2, 2 are provided near both ends of the handle handle 1, respectively. Is provided. In addition, screw portions 6 and 6 are formed at both ends of the handle 1 respectively. The grip 1 is not limited to the illustrated shape, and may be formed in an appropriate shape that is easy to grip, such as a polygonal cross section.
[0009]
One of the gauge balls 2 and 2 has a diameter equal to the diameter of a pachinko ball, 11.00 mm, the other is slightly larger than 11.01 mm, or one is 11.02 mm and the other is 11.03 mm little by little. It is formed with different diameters. Further, screw holes 7 and 7 into which the screw portions 6 and 6 of the grip handle 1 are screwed are formed at the rear ends of the gauge balls 2 and 2, and gauge balls having different diameters are appropriately selected as necessary. It can be easily replaced.
[0010]
Further, protrusions 3 and 3 formed in a columnar shape having a diameter shorter than the diameter of the gauge balls 2 and 2 are integrally provided at the tips of the gauge balls 2 and 2. The protrusions 3 and 3 are provided so that their centers are positioned on the axis of the handle 1, and the tip surfaces 8 and 8 are spherical surfaces having the same center as the center of the gauge ball 2. It is formed with. The axial lengths of the protrusions 3 and 3 are set so that the gauge balls 2 and 2 are always located at a certain distance from the game board 9. For example, if the gauge ball 2 has a diameter of 11.00 mm and the axial length of the projection 3 is set to S, the gauge 3 has a diameter of 11.01 mm. When S-0.005 mm and the gauge ball diameter is 11.05 mm, the axial length of the protrusion 3 is set to S-0.025 mm. In this way, by adjusting the length of the protrusions 3 and 3 for each gauge ball having a different diameter, the widest portion of the gauge ball 2 is fixed from the game board 9 regardless of the gauge ball 2 having any diameter. Will be located in the distance. The protrusions 3 and 3 may be formed separately from the gauge balls 2 and 2, and the tip surfaces 8 and 8 of the protrusions 3 and 3 are the same as the center of the gauge balls 2 and 2. If it is formed of a spherical surface, it may have a cross-shaped cross section as shown in FIG. Further, when the gauge is moved vertically with respect to the game board, the tip surfaces of the gauge balls 2 and 2 do not necessarily have to be spherical, and the tip surfaces may be flat.
[0011]
The present invention is configured as described above, and a method for using the same will be described below with reference to FIG. First, the operator selects a gauge having a gauge ball 2 having a diameter as required. Then, the gauge ball 2 is interposed between the life nails 10 and 10 while holding the gauge in the hand, and the tip surface 8 of the protrusion 3 is allowed to pass while contacting the game board 9. In this case, if the gauge ball 2 seems to pass without receiving resistance, the interval between the life nails 10 and 10 is narrowed by a hammer or the like according to the preference of the operator. If the stagnation occurs due to resistance by 10, the interval between the life nails 10 and 10 is increased.
[0012]
In this case, since the axial length of the protrusion 3 is set so that the position of the gauge balls 2 and 2 is always located at a certain distance from the game board 9, it is necessary to rely on experience and feeling for the position. No one will be able to adjust the nail easily and accurately. Further, when the adjustment is performed, it is only necessary to pass between the life nails 10 and 10 while bringing the protrusion 3 into contact with the game board surface 9, so that the position of the gauge ball 2 is stable without being shaken during the adjustment. It can be carried out.
[0013]
Further, since the tip surface 8 of the protrusion 3 is formed in a spherical surface having the same center as the center of the gauge ball 2, it is not always necessary to make the grip handle 1 orthogonal to the game board 9, and the grip handle 1 is a game. Even if the gauge ball 2 is inclined with respect to the board 9, the gauge ball 2 is kept at a fixed position between the life nails 10 and 10 and can always be appropriately adjusted.
[0014]

In addition, a display window 57 for displaying a scale of a shaft 53 described later is opened at the center portion of the grip handle 50. Further, a kerf 55 for accommodating the arcuate portions 54, 54 of the projections 52, 52 is formed at both tip portions of the gauge balls 51, 51.
[0016]
The shaft body 53 is formed to have a predetermined length longer than the length in the axial direction from one gauge ball 51 to the other gauge ball 51, and is movably inserted into the elongated hole 56 of the grip handle 50. In addition, arc-shaped portions 54 and 54 that are in contact with the game board in adjusting the nail are fixed to both ends of the shaft body 53. Further, a scale is engraved on the outer peripheral surface of the shaft 53 and is displayed on the display window 57 of the grip handle 50.
[0017]
When this nail adjustment gauge is used, first, the arc-shaped portion 54 on one end side of the shaft 53 is pushed in to project the arc-shaped portion 54 on the other end side from the gauge ball 51, thereby forming the protruding portion 52. In this case, the scale of the shaft body 53 is displayed on the display window 57 of the grip handle 50 so that the protruding length of the protruding portion 52 can be easily confirmed. Therefore, it is possible to freely adjust the protrusion amount of the protrusion 52 while viewing the displayed scale.
[0018]
As described above, the gauge shown in the present embodiment is provided with the shaft body 53 (protrusion portion 52) so as to be movable so that the protrusion amount of the protrusion portion 52 can be freely adjusted. Depending on the adjustment, the gauge ball 51 can be positioned at any position from the base side to the head side of the life nail. Also, when using a plurality of gauges with gauge balls 51 having different diameters, the widest portion of the gauge ball 51 can be played regardless of which gauge is used by appropriately adjusting the projection amount of the projection 52 of each gauge. It can be located at a certain distance from the board. In addition, since the protrusion amount of the protrusion 52 can be confirmed by the scale displayed on the display window 57, the protrusion amount of the protrusion 52 can be adjusted very easily while confirming the scale. Further, the adjustment of the protruding amount of the protrusion 52 can be performed very easily because it is only necessary to push the arcuate portion 54 on one end side with a finger or the like to move the shaft 53.
