Description

  The present invention relates to an inclinometer used for measuring the vertical of a gaming machine or measuring an inclination angle from the vertical.

  In pachinko machines, it is known that the ball can be adjusted by giving an appropriate inclination to the board surface. Utilizing the fact that the closer the board surface of the pachinko machine is to an angle, the more the ball gets entangled with the nail. By attaching an appropriate inclination when attaching a pachinko machine or making adjustments afterwards, it is possible to obtain the same effect as when the nail is adjusted more easily.

  The inventors have filed applications such as JP-A-63-226385, JP-A-63-226386, JP-A-10-80563, and JP-A-2002-062131 in consideration of such points. . These relate to an instrument for fixing a pachinko gaming machine to a pachinko gaming machine installation unit with a variable inclination angle.

  Each of these devices is useful, but when using these devices, it will be necessary to check the vertical position of the pachinko machine and check the inclination angle, and the accuracy of measurement is also required. Will be.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an inclinometer that is used for measuring vertical or measuring an inclination angle from the vertical, and can be used easily and has a certain accuracy.

  The inventor of the present application proposes the following inclinometer in order to solve the above-mentioned problems.

The inclinometer of the present invention is an inclinometer for measuring an inclination angle of a surface to be measured in which at least one nail is driven substantially perpendicularly to the surface to be measured, and is longer than the nail and is in use during the use. A plurality of substantially rod-shaped installation legs whose tips are brought into contact with the measurement surface are connected to the base ends of the plurality of installation legs, and the plurality of installation leg tips are connected to the surface to be measured. An inclinometer body whose distance to the surface to be measured is determined to be constant by being brought into contact, and an inclination of a virtual axis that is a virtual axis having a fixed positional relationship with the inclinometer body Inclination angle measuring means provided on the inclinometer body for measuring an angle and at least one of the installation legs, and attached to the inclinometer body by an elastic body (for example, always) A force is applied to the elastic body. A movable body adapted to be moved in a direction away from the inclinometer body along the installation leg by applying an external force that resists the biasing force applied to the movable body. When the external force is not applied in a state where the tip of the installation leg provided with the movable body is in contact with the surface to be measured, the inclination is more than the nail umbrella of the nail. A contact surface is provided at a position close to the meter body, and when the external force is applied, it can be moved to a position farther from the inclinometer body than the nail umbrella of the nail. The nail umbrella of the nail is applied by applying the external force to the movable body in a state where the tip of the installation leg provided with the movable body is in contact with the surface to be measured near the nail. Moved to a position far from the inclinometer body than The contact surface is locked to the surface of the nail umbrella on the surface to be measured, and the contact surface is urged toward the clinometer body by the urging force of the elastic body. The installation leg can be fixed to the surface to be measured.
Normally, pachinko machines have a large number of nails on the board surface that is the surface to be measured, so when measuring the inclination angle of the board surface, these nails become obstacles and it is possible to accurately measure the inclination angle of the board surface. Can not. Therefore, this inclinometer is equipped with a plurality of installation legs that are long enough to avoid such a large number of nails, and the tip of the installation legs is brought into contact with the board surface to keep the distance from the board surface constant. In addition, the inclination angle of a virtual axis having a fixed positional relationship with respect to the inclinometer body is measured. Further, since the movable body provided on at least one installation leg can be fixed to one nail, the inclination angle of the board surface can be measured easily and accurately.
In the inclinometer of the present invention, when fixing the installation leg of the inclinometer to the board surface, an external force is applied with the tip of the installation leg with the movable body in contact with the vicinity of the nail on the board surface. If not, the contact surface of the movable body, which is closer to the clinometer body than the nail umbrella, is farther from the clinometer body than the nail umbrella by applying external force to the movable body. It moves to a position, engages with the surface of the nail umbrella on the surface side, and urges the contact surface against the nail umbrella in the direction of the inclinometer body by the urging force of the elastic body. By using a movable body having such an elastic body, the force with which the installation leg presses the board surface when the installation leg of the inclinometer is fixed to the board surface is always constant. For example, when holding the inclinometer by hand and pressing the installation leg against the board surface, if the force for pressing the installation leg against the board surface is excessive, the flexible board surface will be bent, resulting in In some cases, the tilt angle cannot be measured accurately. In the present invention, in the measurement of the inclination of the board surface by the inclination system, the force for pressing the installation leg against the board surface can be a constant force by the elastic body, so that the above-mentioned problems can be avoided. The accuracy of measurement of the inclination angle can be improved.
The inclinometer of the present invention is such that the installation leg having such a movable body can be detachably fixed to the board surface. Can be released. Thus, the operator can conveniently measure the inclination angle of the board surface while looking at the inclinometer.
The inclinometer installation leg may be configured to be able to move in parallel on the facing surface of the inclinometer body facing the board surface in parallel.

  A groove along the length direction of the installation leg may be provided on the lower surface of the movable body, and the nail may be locked in the groove. By fitting the nail into the groove well, the movable body can be more stably fixed to the nail, and the inclination angle can be easily and accurately measured.

The inclinometer main body can be held with one hand whose vertical direction is the length direction in a state where the tip of the installation leg provided with the movable body is in contact with the surface to be measured near the nail. The movable body may be provided on the installation leg which is formed in a long and narrow shape and is relatively uppermost in the range above the center of gravity of the inclinometer.
By making the inclinometer body into an elongated shape that can be held by one hand with the vertical direction as the length direction, the inclinometer can be easily brought into contact with the surface to be measured. In addition, even if the hand that supports the inclinometer is released by fixing the leg that is above the center of gravity of the inclinometer and is relatively uppermost to the surface to be measured, the weight of the inclinometer itself, It can be avoided that the inclinometer rotates around the installation leg having the movable member. As a result, the stability of fixing to the board surface by the installation legs provided in the movable body becomes stronger.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a best embodiment for carrying out the invention will be described with reference to the drawings.
FIG. 1 shows a state in which the inclinometer 10 is installed on the surface to be measured 20 in this embodiment. FIG. 2 is a perspective view of the inclinometer 10.
The measured surface 20 is a board surface in a pachinko gaming machine, and a plurality of nails 21 are driven therein. The surface 20 to be measured is inclined such that the surface on which the nail 21 is driven is the front surface and the upper portion is the rear. The inclinometer 10 according to the present invention measures the inclination of the board surface. In this embodiment, the surface to be measured 20 can be changed in inclination angle by a known method.

  As shown in FIG. 1, the inclinometer 10 has an inclinometer main body 11 whose length direction is the vertical direction when used. The inclinometer body 11 is not limited to this, but is made of metal and is formed in a rectangular parallelepiped shape. In this embodiment, the inclinometer body 11 which is a rectangular parallelepiped is used in a state where the facing surface 12 facing the measured surface 20 of the inclinometer body 11 is parallel to the measured surface 20. The inclination angle of the measurement target surface 20 from the direction perpendicular to the ground can be measured by the inclination angle of the facing surface 12. The line along the maximum inclination direction on the facing surface 12 is an example of a virtual axis in the present invention.

  The inclinometer body 11 in this embodiment has a back surface 13 that is a surface parallel to the facing surface 12. The back surface 13 is provided with a table-like member 14 having a surface perpendicular to the back surface 13. A plurality of level meters 15 are provided on the table-like member 14 in the direction perpendicular to the back surface 13 as tilt angle measuring means. When the inclinometer 10 is installed perpendicular to the ground, each level meter 15 has an end near the back surface 13 that is higher than the other end, and has an inclination angle A. In this embodiment, the level gauges 15 on the table-like member 14 are installed so as to have different inclination angles A. When the inclinometer 10 is installed on the surface 20 to be measured, if there is a level meter 15 that shows horizontal, the inclination angle A of the level meter 15 is the inclination angle of the opposing surface 12 from the vertical direction with respect to the ground. Matches. As described above, the inclinometer body 11 is installed such that the facing surface 12 is parallel to the surface to be measured 20. Therefore, the inclination angle A that is the inclination angle of the facing surface 12 is an inclination angle of the measurement target surface 20 from a direction perpendicular to the ground. For example, in this embodiment, four level meters 15 are used, and the inclination angle A given to each level meter 15 is 3 degrees, 3.5 degrees, 4 degrees, 4 degrees from the front of FIG. It is 5 degrees. Therefore, when the inclinometer 10 is installed on the surface 20 to be measured, for example, if the level meter 15 that measures 4 degrees is horizontal, the inclination angle of the surface 20 to be measured is 4 degrees. The number of level meters 15 and the inclination angle of each level meter 15 can be determined appropriately. Furthermore, the level meter may not be used as the tilt angle measuring means, and the table-like member 14 may not be used depending on the tilt angle measuring means. For example, instead of the level meter 15, it may be possible to use a tilt angle measuring device controlled by a computer having a tilt sensor inside.

  A substantially rod-shaped installation leg is connected to the facing surface 12 of the inclinometer body 11. For example, two installation legs 30 and 40 each having a prismatic shape are connected to the inclinometer body 11 in this embodiment. These installation legs 30 and 40 need to be longer than the nail 21. Further, in this embodiment, the installation legs 30 and 40 are such that the facing surface 12 and the measurement surface 20 are parallel in a state where the tips of the installation legs 30 and 40 are in contact with the measurement surface 20. The length is such that the distance from the facing surface 12 to the measured surface 20 is constant. That is, the tips of the installation legs 30 and 40 are flush with each other. The number of installation legs need not be two, and may be increased in accordance with factors such as the shape of the inclinometer body 11. In this embodiment, the installation leg has a prismatic shape, but may have another shape as long as it is substantially rod-shaped. For example, it may be a columnar shape.

  Of the two installation legs, the installation leg 30 that is relatively upper in use is in a range above the position of the center of gravity of the inclinometer 10. The installation leg 30 is provided with a movable body 31. In this embodiment, the other installation leg 40 does not have a movable body, but the two installation legs may have a movable body.

FIG. 3 is a diagram showing the internal structure of the installation leg 30 in the vicinity of the movable body 31, and FIG. 4 is an enlarged view of the vicinity of the movable body 31 of the installation leg 30 in FIG. A cavity 32 having a substantially rectangular cross section is present in a portion of the installation leg 30 that is covered with the movable body 31. A first spring 33 is provided inside the cavity 32. The movable body 31 is composed of the first resin body 50 and the second resin body 60, and is configured to be combined so as to sandwich the cavity 32 therebetween. The first resin body 50 has a first protrusion 51. The first protrusion 51 has a plate shape parallel to the length direction of the installation leg 30, and the length of the installation leg 30 is such that the protrusion 51 can be fitted at both ends near the cavity 32. There is a recess 34 having a length parallel to the length direction. The length of the installation leg 30 of the recess 34 in the length direction is longer than the length of the first protrusion 51 in the same direction.
Further, a groove 52 is provided on the lower surface of the movable body 31 so that the nail 21 can be locked in a more stable state.

  The first resin body 50 has a rectangular parallelepiped second protrusion 53 that is inserted into the cavity 32 of the installation leg 30. In this state, the surface in the distal direction of the installation leg 30 of the second protrusion 53 comes into contact with the first spring 33. The first spring 33 is already in a contracted state with the second protrusion 53 being in contact with the first spring 33, and always urges the second protrusion 53 toward the inclinometer body 11. . By moving the movable body 31 away from the inclinometer body 11 along the installation leg 30, the second protrusion 53 further contracts the first spring 33, and the second protrusion 53 is directed toward the inclinometer body 11. The power to urge you to become stronger.

  In this embodiment, the first resin bodies 50 are fitted so that the two first protrusions 51 fit in the corresponding two depressions 34 and are covered with the second resin body 60 from above. The first protrusion 51 can be moved along the recess 34 while being guided in the length direction of the installation leg 30. The first protrusion 51 can be moved only within the range of the length of the recess 34, and accordingly, the moving range of the movable body 31 is also limited.

  The surface closest to the inclinometer body 11 of the movable body 31 is the contact surface 35. The contact surface 35 moves as the movable body 31 moves. The contact surface 35 can be moved from the position a to the position b when the movable body 31 is in the initial state. The position b is a position closer to the measured surface 20 than the surface of the nail 21 on the measured surface 20 side of the nail umbrella 22. As described above, by moving the movable body 31 in the direction of the measured surface 20, a strong force is generated by the first spring 33 to bias the movable body 31 in the direction of the inclinometer body 11. When the movable body 31 is released so that the contact surface 35 contacts the surface of the nail umbrella 22 on the measured surface 20 side, the movable body 31 is engaged with the nail 21 by the biasing force generated in the movable body 31. Can be stopped. At this time, the movable body 31 can be fixed in a stable state by the nail 21 by bringing the nail 21 into contact with the groove 52. The movable body 31 does not have to be made of resin or a rectangular parallelepiped shape, but the nail umbrella 22 does not slide in a portion from the contact surface 35 of the movable body 31 to the lower surface of the movable body 31 with the groove 52. It is preferable that the nail 21 has a shape that can be locked (for example, a shape that is not chamfered) and has sufficient rigidity.

In this embodiment, the installation leg 40 can be moved in parallel in the vertical direction on the facing surface 12 along the length direction of the inclinometer body 11.
There is no particular limitation on the configuration for allowing the installation leg 40 to move along the length direction of the inclinometer body 11, but in this embodiment, for example, a configuration as shown in FIG. It has been adopted.
In this embodiment, the inclinometer body 11 is constituted by a square pipe. A rectangular cut 16 having a long side in the length direction of the inclinometer body 11 is present on the facing surface 12 of the inclinometer body 11. The installation leg 40 is connected to the inclinometer main body 11 with its base end inserted into the opposing surface 12.
Inside the inclinometer main body 11, a fixing plate 70 for fixing the base end of the installation leg 40, and the inside of the inclinometer main body 11 together with the fixing plate 70 fitted with the fixing plate 70, are formed in the above-described notch 16. A moving table 80 that moves along is accommodated.
The fixing plate 70 has a rectangular plate portion 72 provided with a through hole 71 at the center thereof, and two prismatic fixing legs 73 extending in the back direction of the inclinometer main body 11 from two opposite sides of the plate portion 72. And. The installation leg 40 is fixed to the fixing plate 70 by screws 90. The fixing is performed by screwing the screw 90 penetrating the above-described through hole 71 into the base end side surface of the installation leg 40. In order to make this possible, a screw hole 41 is provided in the surface of the installation leg 40 on the side of the inclinometer main body 11 so that the screw 90 can be screwed therein. Further, the diameter of the through hole 71 is set such that the screw portion of the screw 90 passes but the screw umbrella does not pass.
The moving table 80 has a substantially rectangular parallelepiped shape. The movable table 80 is not necessarily limited to this, but is made of resin in this embodiment. Two insertion ports 81 and a cylindrical hole 82 are provided on the surface of the moving table 80 facing the fixed plate 70. The insertion port 81 is a hole whose cross-sectional shape substantially corresponds to the cross-sectional shape of the fixing leg 73, and is provided at a position corresponding to the position of the two fixing legs 73. The cylindrical hole 82 is a hole having a relatively shallow circular cross section. One end of the second spring 100 can be fitted into the cylindrical hole 82.
The fixed plate 70 includes the second spring 100 sandwiched between the movable base 80 and the two fixing legs 73 inserted into the insertion ports 81 of the movable base 80, respectively. It is stored in. In this state, the second spring 100 is in a contracted state with one end abutting against the movable table 80 and the other end abutting against the fixed plate 70. Therefore, the fixed plate 70 is always urged by the second spring 100 in the direction of the measured surface 20 with a constant force. Thereby, the surface on the facing surface 12 side of the fixed plate 70 is in a state of being pressed against the inner wall of the facing surface 12 of the inclinometer body 11. In this state, it is almost impossible to move the installation leg 40 along the notch 16 by a force caused by friction between the fixed plate 70 and the inner wall of the inclinometer body 11. However, if the installation leg 40 is pushed in the direction of the moving base 80 by applying a force capable of further compressing the second spring 100 so that the fixed plate 70 does not come into contact with the inner wall of the inclinometer body 11, the installation leg 40 can be installed. The service leg 40 is easily moved. That is, with this configuration, in this embodiment, the installation leg 40 can be freely moved in the length direction of the cut 16 and the installation leg 40 can be moved to any position in the length direction of the cut 16. It is compatible with fixing with.
However, the installation leg 40 does not necessarily have to be movable, and if the movable direction is parallel to the facing surface 12, the installation leg 40 must be limited to the vertical direction along the length direction of the inclinometer body 11. There is no. Further, the installation leg 30 may be movable as long as it is in a range above the center of gravity of the inclinometer 10.

Next, a method of using the inclinometer 10 will be described.
In using the inclinometer 10, first, the inclinometer 10 is fixed to the measurement target surface 20. As described above, when the inclinometer 10 is fixed to the measured surface 20, the tips of the installation legs 30 and 40 extending from the inclinometer 10 are brought into contact with the measured surface 20.
At this time, the installation leg 30 is brought into contact with the surface to be measured 20 while fitting the appropriate nail 21 into the groove 52 in the movable body 31 of the installation leg 30. At this time, if the other nail 21 interferes when the installation leg 40 is brought into contact with the surface 20 to be measured, the installation leg 40 is cut 16 so that the installation foot 40 and the other nail 21 do not interfere with each other. Move up and down within the range. Then, the movable body 31 is moved from the position a to the position b in a state where the installation legs 30 and 40 are in contact with the surface to be measured 20, and the contact surface 35 of the movable body 31 is locked to the nail 21. When the hand is released from the movable body 31, the movable body 31 moves in a direction in which the contact surface 31 returns to the position a by the strong elastic force generated by the first spring 33 inside the movable body 31. The locking of the surface 35 to the nail 21 is automatically performed when the hand is released from the movable body 31. At this time, the force by which the installation leg 40 is pressed against the surface to be measured 20 is a constant force due to the elastic force of the elastic body first spring 33.
In this embodiment, the inclination angle of the virtual axis of the inclinometer 10 is determined by the two points where the installation legs 30 and 40 abut on the surface to be measured 20. The inclination angle of the virtual axis is indicated by the inclination angle of the level gauge 14 indicating the horizontal among the plurality of level gauges 14 installed at different angles, and the inclination angle of the measured surface 20 is determined by the inclination angle. Measured. The operator can perform necessary work such as adjustment of the inclination angle of the surface to be measured 20 while looking away from the inclinometer 10 while viewing the inclination angle of the surface to be measured 20 indicated by the inclinometer 10. .
