Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a game machine body holding device for holding a passenger seated on a seat of a game machine to which motion such as rotation is applied.

(Prior art) Roller coasters, rotating swings shown in Japanese Utility Model Publication No. Sho 59-100487, flying discs shown in Japanese Utility Model Publication No. 57-5007, and amusement vehicles showing movements similar to the flight on the moon. The play machine of the type is provided with a body holding device for holding a passenger sitting in the seat so that the body is not thrown out of the seat under the influence of movement such as turning.

In such a body holding device, a rotatable arm is arranged on the front side of the passenger, and the arm is restrained from the engagement between the engagement groove and the engagement protrusion that can be engaged and disengaged to hold the passenger in the seat. It is being done.

Specifically, for example, as in Japanese Utility Model Laid-Open No. 50-46276, an arm for holding a body is arranged on the front side of the seat so that the arm can be tilted forward, and a large number of groove portions are formed at the end of the arm on the side of the pivot point. A tooth portion forming plate formed on the outer periphery is provided, and a claw body having a claw portion serving as an engaging convex portion at the tip is rotatably provided around the tooth portion forming plate. Then, the claw body is rotationally driven by a drive mechanism composed of a link mechanism or the like, and the claw portion is engaged with the groove portion of the tooth portion forming plate from the rotation, and the movement of the arm that has rotated to the front surface of the body. Are restrained, or the engagement is released to release the restraint.

(Problems to be solved by the invention) By the way, in such a body holding device, in order to prevent the function of holding a passenger's body from being lost when the play machine is in operation, the body holding device is usually placed in a direction away from the passenger side. The shapes of the engagement protrusion and the engagement groove are formed so that the engagement protrusion enters the engagement groove when an external force is applied to the arm.

However, although such an engaging means certainly does not impair the holding function, when the restraint of the arm is released, there is a fast passenger, and the passenger disengages the arm from the body in order to remove it from the body. When a force is applied in the direction, the length of the lever member, which is a mechanical component, is shorter than the length of the arm around the body, so the force that the passenger tries to remove is driven. There is a problem that the release movement from the mechanism is restricted. If this happens, the parts of the drive mechanism may be damaged. Further, as described in the above publication, in the case of a body holding device configured to release the restraint of a plurality of arms by a single driving source, any one of the engaging means is engaged and locked. If it is done, there is a problem that other arms are also restrained and all the arms cannot be released.

The present invention was made in view of such a problem, and the purpose is to release the drive mechanism even if a force is applied from the passenger to the arm to release the restraint of the body. It is an object of the present invention to provide a body holding device for a game machine, which does not require an unreasonable force and which does not affect other engaging parts even if any one of the engaging parts bites.

(Means and Actions for Solving Problems) A body-holding device for a game machine according to the present invention comprises a rotating plate provided at end portions of a plurality of arms on a rotation center side, and a plurality of rotating plates driven by a drive source. The engaging groove and the engaging convex portion are respectively provided between the lever member and the lever member, and the engaging is structured such that the engaging proceeds when an external force is applied in the direction of removing the arm from the passenger side, Also, the plurality of lever members are simultaneously rotated by the drive source, and the rotary member is provided between each lever member and the drive source, and the power is transmitted between the rotary shaft member and the rotary shaft member. Is provided, and an elastic connecting body is provided between the rotating shaft member and the rotating member in the rotating power transmitting mechanism. The elastic connecting body connects the rotating shaft and the rotating member. When the relative rotation of the It is designed to give a restoring force to the original.

With this configuration, when an external force is applied to the arm restraining the body from the passenger side in the direction of removing the arm, the engagement between the engaging groove and the engaging convex portion progresses, so that the body is restrained. There is no worry of being released.

Moreover, in this case, the force applied to the arm is transmitted to the lever member through the rotating plate, and the lever member has a rotation power transmission mechanism including a rotation shaft member and a rotation member between the lever source and the drive source. Since the rotating power transmission mechanism is provided with the elastic connecting body, the elastic connecting body is elastically deformed to allow the lever member to rotate, thereby preventing the engagement groove and the engaging convex portion from being caught. Also, it prevents excessive force from being transmitted to the drive source. Therefore, it is not necessary to restrain the movement of the engaging portions at other locations.

Further, when the elastic coupling body is deformed, the elastic coupling force is stored, and when a driving force in the releasing direction is applied in this state, the elastic coupling force acts in addition to this driving force. The engagement between the mating groove and the engagement protrusion can be automatically released.

Has become. The detailed structure around the safety bar 16 is shown in FIGS. 6 and 7, and the drive source and the link mechanism are also shown.
The structure around 17 is shown in both FIG. 4 and FIG.

Since the structure around the safety bar 16 is the same, if one of them, for example, the one at the center of the seat 8 is explained, 20 is a pillar installed on the upper surface of the vehicle floor base 9, and 21 is the pillar 20. Is a frame provided at the upper end of the.

The frame 21 is configured by vertically arranging two opposing plate members 21a and 21b with the plate surfaces facing the front via a connecting plate 22 on the column 20. A rotary shaft 24 extending in the front-rear direction of the seat 8 is rotatably supported by using two bearings 23a and 23b provided on the left and right sides of the frame 21, respectively. Then, at the front end (the direction indicated by the arrow P in FIG. 6) of the rotary shafts 24, the tubular support body 25 forms a connecting tool 25a in a direction perpendicular to the rotary shafts 24. They are connected to each other and form the entire safety bar 16. That is, the support body 25 can rotate in front of the front seat 8 about the rotation axis 24, and when the support body 25 is located in front of the seated passenger, the detachment of the passenger can be restrained. ing. Then, the plate member 21a and the plate member of each rotating shaft 24, 24

A swing lever 30 (corresponding to a lever member of the present invention) extending toward the cam plate 27 is connected to a shaft portion surrounded by the plate members 23a and 23b of 8, 28. Then, a roller 31 (corresponding to the engaging convex portion of the present invention) which can be engaged with and disengaged from the engaging groove 26 of the cam plate 27 is rotatably connected to the tip end portion of the swing lever 30, and the support body 25 is attached. If the swing roller 31 is engaged with the engagement groove 26 in a state in which the movement of the passenger is restrained, the seventh
In that state, the safety bar 16
Can be fixed. More specifically, in the engagement structure, the engagement groove 26 has a substantially J-shaped notch at a position where the angle θ formed by the center of the rotating shaft 24 and the axis of the support body 25 is set to be smaller than “90 °”. Has a structure. The swing lever 30 has a structure in which the roller 31 is engaged with the engagement groove 26 from an oblique direction, and if a force is applied to the safety bar 16 in the engagement state, the engagement is released. It also has a structure in which the roller 31 advances, that is, the roller 31 enters the engaging groove 26. In other words, the structure is such that the function of holding the passenger's body is not lost. 32 is a cam plate provided on the frame 21
It is a stopper shaft for positioning a state in which the movement of passengers is restrained by engaging with the circular arc 27a on the outer periphery of 27.

On the other hand, a link 33 is provided at the rear end of each of the rotary shafts 28, 28 along a direction that makes an acute angle with the swing lever 30 and extends to the left and right. The link mechanism 17 is provided at the remaining end of each link 33, and the swing lever 30 is operated by receiving power from the drive source provided on the platform 1a side.

Specifically, the link mechanism 17 is rotatably connected to the other end of the link 33 via a vertically extending rod 34 and a pin 35. Further, the lower ends of these elevating rods 34 are connected to a long transmission shaft 36 that is rotatably provided on the vehicle floor base 9 over the row of seats 8. In addition to this, a cam 38 having a forked portion 38a at the tip is fixed to the shaft portion of the transmission shaft 36,
An L-shaped receiving portion 34a (see FIG. 5) is provided at the lower end of the lifting rod 34, and the receiving portion 34a is rotatably connected to the inside of the forked portion 38a of the cam 38. The elevation rod 34 can be moved up and down by the rotation of the transmission shaft 36. However, 39 indicates a bearing for rotatably supporting the transmission shaft 36.

Further, the ends of the two transmission shafts 36 arranged corresponding to this seat row are connected by the parallel link 37, and for example, the shaft portion of the transmission shaft 36 on the rear seat side is used for inputting downward. Long lever 40
Is provided so as to be able to receive a driving force from the outside. A compression coil spring 41 for biasing the lever 40 backward is connected to the lever 40, and normally biases the swing lever 30 in the engaging direction. In other words, the tip of the rocking lever 30 is constantly cambed by elastic force so that the function of holding the passenger's body is not lost during operation of the play machine.
When the lever 40 is biased toward the 27 side and the lever 40 is rotated forward against the compression coil spring 41, the tip end of the swing lever 30 can be rotated in the disengaging direction.

On the other hand, on the platform 1a side, a pushing lever 42 is rotatably erected on the front side at a base portion directly below the vehicle floor base 9. The length of the pushing lever 42 is set so that the tip of the pushing lever 42 intersects with the end of the lever 40 of the vehicle floor base 9. A power source for raising and tilting the pushing lever 41 forward, for example, a hydraulic cylinder 43, is rotatably connected to the pushing lever 42 in the middle of the pushing lever 42, and the platform 1a supports the vehicle floor base 9. From the arriving state, the pushing lever 42 is erected by the hydraulic cylinder 43 and the roller 40a provided at the tip of the lever 40 is pushed forward to pass through the parallel link 37, the transmission shaft 36, the lifting rod 34 and the link 33. The tip of the rocking lever 30 can be rotated toward the disengagement side. Of course, the pushing lever 42 is the lever 40 when stopped on the platform 1a.
It is installed corresponding to the position of. However, 44
Shows a bracket for rotatably supporting the pushing lever 42 and 45 for rotatably fixing the hydraulic cylinder 43.

In the body holding device 15 configured in this way, the rotation power transmission mechanism is provided in the middle of the power transmission path connecting the lifting rod 34 located on the drive source side and the swing lever 30. That is, the rotary power transmission mechanism is a mechanism composed of a rotary shaft member and a rotary member that exchanges rotary motion with the rotary shaft member. For example, the pin 35 or the rotary shaft 28 is rotated by the rotary member. It corresponds to a shaft member, and the link 33 and the swing lever 30 correspond to a rotating member. More specifically, between the pin 35 and the link 33, between the link 33 and the rotating shaft 28, and between the rotating shaft 28 and the swinging shaft 28. A mechanism for transmitting the rotational movement to and from the moving lever 30 is configured. A rubber spring 47 (elasticity of the present invention), which is a main part of the present invention, is attached to one of the rotational power transmission mechanisms for transmitting the rotational movement, for example, to the connecting portion 15a composed of the rotational shaft 28 and the link 33. Corresponding to the connecting body) is interposed. Its structure is shown in FIGS. 1 and 6.

Here, the structure around the rubber spring 47 will be described. For example, the rubber spring 47 has a cylindrical outer case 48 in which the outer side is circular and the inner side is square, and the midpoint of the square side of the outer case 48 is An inner rectangular case 49 composed of connecting edges 49
Is rotatably arranged, and rubber members 50 are respectively inserted in cavity portions having a triangular cross section formed at four positions between the inner case 49 and the outer case 48. Then, such a rubber spring 47 is attached to the plate surface of the link 33 using the key 53. On the other hand, the rear end of the rotary shaft 28 is formed in a square shape. Then, the square portion is fitted into the inner case 49 of the rubber spring 47 so as to be provided between the rotary shaft 28 and the link 33 that receives the rotary shaft 28. By mounting the rubber spring 47, the fixed connecting portions are elastically and rotatably connected to each other, and an unreasonable force applied to the link 33 is absorbed by the elastic deformation of the rubber member 50. .

Reference numeral 51 is a torsion spring for causing the safety bar 16 wound around the rear end side of the rotary shaft 24 to be flipped up to the body open position shown by the chain double-dashed line in FIG. 4, and 52 is a cam plate 27. It is a shallow groove for holding the safety bar 16 in an open state provided on the outer periphery.

Then, when using such a large-sized play machine, first, a passenger is seated on each seat 8 from the vehicle floor base 9 stopped on the platform 1a by a stop mechanism (not shown). On this occasion,
The safety bar 16 consists of a shallow groove 52 and a roller at the tip of the swing lever 30.
Since it is held in a state where it is greatly opened upward as shown by the chain double-dashed line in FIG.
Passengers can sit without difficulty. At this time, the hydraulic cylinder 43 is contracted.

Then, when the passenger is seated, each safety bar 16 is lowered. As a result, the support body 25 of each safety bar 16 is arranged in front of each seated passenger. Then, when the roller 31 is lowered to a predetermined position, the roller 31 is engaged with the J-shaped engagement groove 26 to fix the position of the support body 25.

Here, since the position of the engaging groove 26 is close to the support body 25 side, and further, the roller 31 is engaged with the engaging groove 26 obliquely from the support body 25 side, for example, during operation, the support body
The safety bar 16 will not be released even if a force such as lifting is applied to the 25, and always restrains the seated body from coming out of the seat 8 forward. In other words, the passenger's body is surely retained.

After that, if the stop mechanism is released and the hydraulic motors 6, 6 are operated, the vehicle platform 9 turns with the turning arm 4 while maintaining the normal position as shown by the arrow in FIG. Passengers will enjoy the movement.

Then, when the predetermined operation is completed, the vehicle floor base 9 stops again on the platform 1a. Then, along with the stop, the hydraulic cylinder 43 extends, the push-out lever 42 is raised, and the tip of the lever 40 protruding from the lower portion of the vehicle floor base 9 is pushed forward. Then, the transmission shaft 36 on the rear seat side rotates to the rear side (clockwise) and at the same time, the parallel link 37
The transmission shaft 36 on the front seat side also rotates rearward through the elevator shafts, and the lifting rods 34 of the seats 8 are raised. As a result, each link 33 is pushed upward, and the swing lever 30 is rotated in the disengagement direction about the rotation shaft 28 as a fulcrum. Accordingly, the roller 31 disengages from the engagement groove 26, and the safety bar 16 is released from being fixed. That is, if the passenger then pushes the support body 25 upward to open the front of the seat 8, the seat 8
You will be able to get off the ground.

Here, when releasing such restraint, if there is a passenger with a quick mind and a force is applied from the passenger toward the support body 25 in order to remove the safety bar 16 from the body, There is concern that the release motion with the roller 31 may be constrained by the force applied by the passenger.

However, according to this invention, the rubber spring 47 is interposed between the connecting portions formed by the rotating shaft 28 and the link 33. This is a safety bar 16 that causes the release movement to be constrained.
Unreasonable force from the rubber member that constitutes the rubber spring 47
It is absorbed by 50 elastic displacements. Specifically, for example, 20
The elastic force of the rubber member 50 absorbs the displacement up to the angle of °.

However, even if the engagement cannot be released, the parts of the drive mechanism, such as the elevating rod 34, will not be damaged, and damage can be avoided in advance.

Further, even if the drive source 43 is the same, the movement of the other lifting rods 34 that actuate the other support bodies 25 is not restricted, so that the other support bodies 25 have the same structure as the two-dot chain line in FIG. Smoothly release the restraint of passengers.

Moreover, if the passenger loosens the force to push up the support body 25, the force accumulated in the rubber member 50 acts on the swing lever 30 as a force to release the engagement, and the engagement is quickly released. It does not impair the timing at which the roller 31 disengages from the engagement groove 26.

In this case, the lift rod 34 may be lifted by the action of the hydraulic cylinder 43 in the state where the passenger who is quick to push up the support body 35, but in this case, in addition to the force accumulated in the rubber member 50, the lift rod 34 is lifted. When the rotating torque is applied as the rod 34 rises, and the passenger releases the support body 35, the swing lever 30 is rotated in the releasing direction and the roller 31 is engaged with the engaging groove 26.
Therefore, the support body 35 is automatically rotated upward under the force of the torsion spring 51. That is, the function of the body holding device 15 can be effectively and sufficiently fulfilled.

In one embodiment, the present invention is applied to the connecting portion between the rotary shaft 28 linked to the swing lever 30 and the link 33, but the invention is not limited to this, and the link 33 is used as a rotary power transmission mechanism linked to the swing lever 30. A rubber spring 47 may be provided between the connecting portion between the lifting rod 34 and the lifting rod 34. Further, although the rubber spring is used as the elastic connecting body in the embodiment, the structure is not limited to this, and for example, a coil spring may be used instead of the rubber spring, and the structure of the elastic connecting body is not limited.

[Effects of the Invention] As described above, according to the present invention, when the restraint of the body is released, when a force is applied from the passenger to the arm, the elastic displacement of the elastic coupling body causes the excessive force. You will be able to miss.

Therefore, even if a force is applied from the passenger to the arm to remove it, it is not necessary to apply an unreasonable force to the components of the drive mechanism, and it is possible to prevent the drive mechanism from being damaged.

Moreover, when the force from the passenger is relaxed, the engagement can be quickly disengaged by the force accumulated in the elastic coupling body.
