Description

  The present invention relates to a movable object unit having a movable object driven via a rack member and a pinion member, and more particularly to a movable object unit having a movable object that moves in an oblique direction inclined with respect to the vertical direction.

  In a pachinko machine, a ball that has been bulleted flows down a game area (an area formed on or near the game board surface for realizing a game or production by the flow of the game ball). In the process of flowing down, the game ball turns while colliding with a game nail (also referred to as a gauge) or a windmill in the game area, and the flow direction changes. As a result, a predetermined prize ball is paid out when a game ball wins at various winning holes arranged on the game area, while a prize ball flows into the out port without winning at any winning hole. Will not be paid out. The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the game ball flowing down and expecting the game ball to be won and the prize ball paid out.

  There are various game areas for realizing games based on the flow of game balls, such as a winning device having a entrance for a game ball to enter, a display device for displaying a game state, a movable object unit having a movable object, etc. These members are arranged. For example, Patent Document 1 describes a movable object unit in which a pair of drive doors are arranged in front of a display device.

JP 2007-61488 A

  The movable object unit described in Patent Document 1 is retracted to a pair of drive doors arranged so as to be movable in the left-right direction on the front side of the display means, a fully closed position where the drive doors are in contact with each other, and both left and right sides of the display means. A drive mechanism that opens and closes between the fully open position. The drive mechanism has left and right racks provided along the lower end side or upper end side of the left and right drive doors, and a pinion that meshes with the left and right racks, and the drive doors move along the left and right racks.

  When the movable door unit is moved to the fully open position, the rear display device can be seen, and when the drive door is moved to the fully closed position, the front of the display device can be blocked, thereby realizing different effects. Can do. However, if the drive door tilts during movement and the relative position of the pair of drive doors shifts, the front of the display device may not be reliably blocked.

  In view of such a problem, the movable object unit described in Patent Document 1 is provided with an inclination correcting means for correcting the inclination of the drive door when the drive door is located at or near the fully closed position. By adjusting the inclination of the drive door to the correct angle by the inclination correcting means, the front of the display device can be reliably closed.

  However, in a configuration in which the left and right racks are arranged on the lower end side, if the weight of the drive door acts on the left and right racks, the left and right racks may be distorted and a vertical displacement of the left and right racks may occur. When the left and right racks are displaced, the drive doors moving along the left and right racks are also displaced in the vertical direction, and the driving force of the drive means may not be smoothly transmitted to the left and right racks.

  The present invention has been made in view of the above circumstances, and provides a movable object unit capable of suppressing the displacement of the rack member in the movable object unit that drives the movable object by the rack member and the pinion member. This is an exemplary problem.

  A movable object unit according to an exemplary aspect of the present invention includes a rail member, a slide member that slides relative to the rail member, a rack member that is fixed to the slide member, and that slides together with the slide member, and meshes with the rack member. A pinion member, drive means for rotationally driving the pinion member, and a movable object connected to the rack member and slidably moved together with the rack member and the slide member. The rail member, the slide member, and the rack member are arranged in the vertical direction. Are arranged so as to be slid in an oblique direction.

  The movable object is connected to the rack member, and slides as the rack member slides. The rack member is fixed to the slide member, and slides together with the slide member. That is, the movable object slides together with the slide member via the rack member. The slide member moves along the rail member, and the rail member serves as a guide for the slide member. As described above, since the slide member and the rail member that serve as a guide for the rack member that moves together with the movable object are provided, the displacement of the rack member and the movable object can be prevented.

  Further, for example, by making the slide member and the rail member made of metal having relatively high rigidity, it is possible to further effectively prevent the positional deviation of the rack member and the movable object that move together with the rail member and the slide member.

  The rack member is configured such that the driving force of the driving means is transmitted through the pinion member. If the rack member is displaced, the relative position between the rack member and the pinion member is displaced, and the transmission force of the drive means may not be transmitted reliably. However, by fixing the rack member to the slide member, it is possible to increase the rigidity of the drive mechanism of the rack member and prevent the rack member from being displaced. Therefore, a shift in the relative position between the rack member and the pinion member can be prevented, and a reduction in driving force transmission efficiency can be prevented.

  Specifically, by preventing the relative position between the rack member and the pinion member from being shifted, the distance between the pitch points can be kept substantially constant, and the torque transmitted from the pinion member to the rack member is reduced. Can be prevented. Furthermore, by keeping the distance between the pitch points substantially constant, the meshing of the rack member and the pinion member is stabilized, and tooth wear can be prevented. Here, the pitch point is a point on the pitch line and the pitch circle, and is a point that meshes with each other in the rack member and the pinion member.

  In addition, the rail member, the slide member, and the rack member are arranged to be inclined with respect to the vertical direction, and are configured to slide in the oblique direction. Therefore, compared to the configuration in which the rail member slides in the vertical direction. Thus, the load on the driving means can be reduced, and the required torque for driving the slide member, the rack member, and the movable object can be reduced. By reducing the required torque, it is possible to reduce the size of the driving means and improve the space efficiency.

  Furthermore, since the rack member is directly fixed to the slide member, it is not necessary to provide a holding mechanism for the rack member mounting structure, and the rigidity of the rack member can be increased. Compared with the configuration in which the holding mechanism is provided, the movable object unit can be downsized and the space efficiency can be improved.

  The pinion member includes a first pinion member and a second pinion member that meshes with the first pinion member. The first pinion member is arranged to mesh with the rack member, and the second pinion member is The driving means may be connected to the driving means, and the driving force of the driving means may be transmitted to the rack member via the first pinion member and the second pinion member.

  When an impact force is applied to the first pinion member, such as when a movable object connected to the rack member falls by connecting the rack member and the driving means via the first pinion member and the second pinion member. It is possible to disperse the impact force related to the above and prevent damage to the connecting portion and the motor. Specifically, the impact force acting on the first pinion member and the second pinion member due to the backlash between the first pinion member and the rack member and the backlash between the first pinion member and the second pinion member. Can be dispersed and absorbed to reduce the impact force acting individually.

  The movable object unit further includes an arm member that connects the movable object and the rack member, and a guide member that guides the sliding movement of the rack member. One end of the arm member is connected to the rack member, and the arm member The other end of the movable member is connected to the movable object, the center of gravity of the movable object is disposed at a position shifted from the plane including the sliding direction of the rack member, and the guide member is disposed on one end side of the arm member, It is desirable to be configured to prevent the rack member from falling in a direction perpendicular to the plane based on the weight of the movable object.

  The center of gravity of the movable object is arranged at a position shifted from the plane including the sliding direction of the rack member. Therefore, a tensile force in a direction perpendicular to the plane including the sliding direction acts on the rack member due to its own weight. The action of the tensile force may cause the rack member to fall in a direction perpendicular to the plane including the sliding direction. When the rack member falls down, the rack member and the pinion member are displaced from each other, which may reduce transmission efficiency.

  However, by providing a guide member that prevents the rack member from falling in the direction orthogonal to the plane based on the weight of the movable object, the movable object is prevented from falling, and the rack member and the pinion member are prevented from being displaced. A decrease in transmission efficiency can be reduced.

  Furthermore, since the guide member is disposed on one end side of the arm member connected to the rack member and is provided relatively close to the rack member, it is possible to effectively prevent the rack member from falling over. it can. In particular, when the arm member is a relatively long member, the distance between the movable object and the rack member is relatively long, so that the weight of the movable object acts on the rack member relatively large. However, by providing the guide portion, it is possible to reduce the weight of the movable object acting on the rack member, and to prevent a position shift (falling) or the like due to the weight.

  The guide member prevents the rack member from collapsing in a direction perpendicular to the plane including the sliding direction. Specifically, the guide member is disposed in contact with the rack member in the direction in which the rack member falls, and contacts the rack member. An example of a configuration that prevents the rack member from collapsing by contact is possible.

  The guide member may be configured to guide the sliding movement of the rack member or the arm member together with the function of preventing the rack member from falling. Specifically, a rotating body that rotates and moves along the rack member or arm member, or a rod that is inserted into a hole formed in the rack member or arm member and slides along the hole of the rack member or arm member. A member can be illustrated.

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, the distance between the pitch points can be kept substantially constant by increasing the rigidity of the rack member mounting structure and preventing the relative position of the rack member and the pinion member from shifting. It is possible to suppress a decrease in transmission efficiency from the member to the rack member. In addition, since the rigidity of the rack member mounting structure is increased by directly fixing the rack member connected to the movable object to the slide member, it is not necessary to provide a holding mechanism for the rack member mounting structure. The rigidity of the structure can be increased. Therefore, compared with the structure which provides a holding mechanism, a movable object unit can be reduced in size and space efficiency can be improved.

A second movable object 51 that rotates about the first rotation shaft 51a is provided on the right side of the first movable object 46, and the second rotation shaft 61a is centered on the left side of the first movable object 46. A third movable object 61 that rotates is provided.

  3 to 6 show a state in which the first movable object 46 is located at the upper end. The first movable object 46 is configured to move obliquely downward to the left from the state shown in FIGS. FIG. 7 is a diagram showing a state in which the first movable object 46 is in the upper end position, and FIG. 8 is a diagram showing a state in which the first movable object 46 is in the lower end position. The first movable object 46 moves between the upper end position and the lower end position. 7 and 8, the first movable object 46, the second movable object 51, and the third movable object 61 are omitted for the explanation of the drive mechanism of each movable object.

  The second movable object 51 is connected to a fourth pinion member 53 that meshes with a third pinion member 52 (see FIG. 1) that is pivotally supported by the first base member 8, and the third pinion member 52 is moved by a motor (not shown). By being rotated, it is configured to rotate together with the fourth pinion member 53.

  The second movable object 51 is connected to the first movable object 46 via the first connection member 54. The 1st connection member 54 is comprised by the several member connected so that rotation was possible. The left end of the first connection member 54 is rotatably connected to a connection plate 48 fixed to the rear surface of the first movable object 46, and is connected to the first movable object 46 via the connection plate 48.

In a state where 46 and the second movable object 51 are connected, each movable object can be moved independently.

  The third movable object 61 is connected to a sixth pinion member 63 that meshes with a fifth pinion member 62 (see FIG. 1) that is pivotally supported by the first base member 8, and the fifth pinion member is driven by a motor (not shown). By rotating 62, it is comprised so that it may rotate with the 6th pinion member 63. FIG.

  The third movable object 61 is connected to the first movable object 46 via the second connection member 64. The 2nd connection member 64 is comprised by the several member connected so that rotation was possible. The right end of the second connection member 64 is rotatably connected to a connection plate 48 provided on the rear surface of the first movable object 46, and is connected to the first movable object 46 via the connection plate 48. Has been. The left end of the second connection member 64 is rotatably connected to the third movable object 61.

  Thus, since the 1st movable object 46 and the 3rd movable object 61 are connected by the 2nd connection member 64 comprised by the several member connected rotatably, the 1st movable object which implement | achieves a different motion. With the 46 and the third movable object 61 connected, each movable object can be moved independently.

  Further, the metal rail member 41 constituting the drive mechanism of the first movable object 46 is fixed to the flat plate-like second base member 11. The slide member 42 is engaged with the rail member 41 and slides relative to the rail member 41. A rack member 43 is directly fixed to the rear surface of the slide member 42. A pinion member 44 that meshes with the rack member 43 is provided on the right side of the rack member 43. By directly fixing the rack member 43 to the metal slide member 42 having a relatively high rigidity, the rigidity of the mounting structure of the rack member 43 can be increased and the displacement of the rack member 43 can be prevented.

  The pinion member 44 includes a first pinion member 44a and a second pinion member 44b that meshes with the first pinion member 44a. The first pinion member 44 a and the second pinion member 44 b are rotatably connected to the second base member 11. The first pinion member 44 a is disposed so as to mesh with the rack member 43. The second pinion member 44 b is connected to the motor 45 and is driven to rotate by the motor 45.

  The driving force of the motor 45 is transmitted to the rack member 43 via the first pinion member 44a and the second pinion member 44b. Therefore, when the motor 45 is driven to rotate, the first pinion member 44 a and the second pinion member 44 b rotate, and the rack member 43 slides together with the slide member 42.

  An arm member 47 is connected to the left end of the rack member 43. A right end (one end) 47 b of the arm member 47 is fixed to the rack member 43, and a left end (other end) 47 a of the arm member 47 is fixed to the first movable object 46. Since the arm member 47 is fixed to the rack member 43, the arm member 47 slides with the slide movement of the rail member 41, the slide member 42, and the rack member 43, and slides the first movable object 46 in the diagonally up and down direction.

  The left end 47 a of the arm member 47 is rotatably connected to a connection plate 48 provided on the rear surface of the first movable object 46. The arm member 47 is substantially flush with the plane P including the sliding direction of the rack member 43. Further, the center of gravity G of the first movable object 46 connected to the left end 47a of the arm member 47 is located in front of the plane P including the sliding direction of the rack member 43 (see FIG. 6). The weight of the first movable object 46 acts forward of the arm member 47. Therefore, a tensile force in the direction X orthogonal to the plane P including the sliding direction acts on the arm member 47, and the arm member 47 may fall in the orthogonal direction. In order to prevent the arm member 47 from falling due to the weight of the first movable object, a rotating body 49 as a guide member is provided.

The rotating body 49 is disposed on the upper part on the front side of the arm member 47 and on the lower part on the rear side. In this way, by disposing the rotating body 49 so as to be separated from the upper part on the front side and the lower part on the back side, the first movable object 46 is effectively prevented from falling due to its own weight (falling in the direction in which the front is lowered). can do.

  FIG. 10 is an enlarged partial view of the rack member 43, the first pinion member 44a, and the second pinion member 44b shown in FIG. At the point where the rack member 43 and the first pinion member 44a mesh with each other, the pitch line Q1 that meshes with the teeth of the first pinion member 44a in the rack member 43 is the pitch circle Q2 that meshes with the teeth of the rack member 43 in the first pinion member 44a. Tangent. In a state where the pitch circle Q2 and the pitch line Q1 are in contact, the pitch point (point on the pitch line Q1) R1 of the rack member 43 and the pitch point (point on the pitch circle Q2) of the first pinion member 44a. R2 maintains a substantially constant distance.

  For example, if the rack member 43 is displaced, the relative position with respect to the first pinion member 44a is displaced, and the distance between the pitch points cannot be kept substantially constant. If the distance between the pitch points is not kept constant, there is a possibility that the transmission efficiency may be reduced, or the teeth may be poorly engaged and the teeth may be worn out. However, by increasing the rigidity of the mounting structure of the rack member 43 and preventing the displacement of the rack member 43, it is possible to prevent a decrease in transmission efficiency and tooth wear.

  Further, the first movable object 46 is connected to the motor 45 via the arm member 47, the rack member 43, the first pinion member 44a, and the second pinion member 44b. By connecting the first movable object 46 and the motor 45 via the two pinion members, the impact force when the impact force acts on the rack member 43 such as when the first movable object 46 falls is distributed. Thus, the impact force acting individually can be reduced, and damage to the connecting portion and the motor 45 can be prevented.

  Specifically, the backlash between the first pinion member 44a and the rack member 43 and the backlash between the first pinion member 44a and the second pinion member 44b are used to reduce the impact force acting on the rack member 43. It can be absorbed and reduced. Furthermore, by providing backlash at a plurality of locations, it is possible to disperse the impact force, reduce the impact force acting individually, and prevent damage to the connecting portion and the motor 45.

  According to the movable object unit 40 configured in this way, the rack member 43 is directly fixed to the relatively rigid metal slide member 42, thereby effectively increasing the rigidity of the mounting structure of the rack member 43, The position shift of the rack member 43 can be prevented. By preventing the displacement of the rack member, it is possible to prevent the displacement of the relative position between the rack member and the pinion member, thereby preventing the transmission efficiency from being lowered and the teeth from being worn.

  Further, by connecting the first movable object 46 and the motor 45 via the two pinion members, the impact force acting on the first movable object 46 and the like is dispersed and absorbed, and the impact on the connecting part between the members and the motor is achieved. The force can be reduced.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary.
