Description

  The present invention relates to a car for a ferris wheel.

2. Description of the Related Art Conventionally, a manual door that is manually opened and closed has been adopted as a passenger door of a ferris wheel car (see, for example, Patent Document 1). For this reason, the platform needs to be staffed to open and close the passenger door of the car. Since the Ferris wheel is a car that revolves around the trajectory repeatedly, the car regularly enters and exits the platform regularly. During the short period of time when the car is located on the platform, the passenger must keep opening and closing the doors repeatedly, which means that heavy labor is imposed. And this clerk must also pay attention to the safety of the platform, such as the safety of players who get on and off the car at the same time, but due to heavy labor as mentioned above, attention to safety is distracted For example, there is a risk of causing a mistake that the passenger door is not properly opened and closed.

In other words, the balance of the car 1 that is particularly necessary when the automatic door 9 is opened and the player stands up and gets off can be secured, and a good sense of stability can be secured in the car 1 so that the player can get on and off. Safety can be ensured.

Also, the car of the Ferris wheel according to claim 2, Oite to claim 1, the lower portion of the horizontal center portion of the car body 10, characterized in that a door opening and closing mechanism 11. According to this, since the center of gravity can be located below the car 1, the distance between the center of gravity and the hanging position from the rotating body 5 located on the upper part of the car 1 can be increased. The swing width around the car can be reduced, and the stability of the car 1 can be enhanced.

  The present invention has an advantage that a good weight balance can be secured in a car that employs an automatic door as a passenger door.

  As shown in FIGS. 3 and 4, the ferris wheel A of this example has a pair of support columns 3 erected from an installation surface 2 such as the ground, and a horizontal shaft 4 is installed between the upper ends of the pair of support columns 3. The circular rotating body 5 is pivotally supported on the horizontal shaft 4 so that the rotating body 5 is rotated on the vertical surface, and a large number of cars 1 are arranged on the outer peripheral portion of the rotating body 5 in the circumferential direction. The platform 6 is provided on the installation surface 2 for getting on and off the player's car 1. According to this Ferris wheel A, the car 1 rotates on a circular locus substantially along the outer diameter shape of the rotating body 5, and the platform 6 is provided along the lower end portion of the turning locus of the car 1. .

  As shown in FIGS. 1 and 2, the car 1 of this example has a substantially circular outer shape when viewed from the front and a substantially rectangular outer shape when viewed from the side, that is, a side-by-side columnar shape. The main body is composed of a car body 10 provided in an outer shape. For convenience, the arrow a direction is referred to as the front, the arrow b direction is referred to as the rear, and the arrow c direction is referred to as the left-right direction. An air conditioner 13 is mounted on the ceiling surface 10c of the car body 10, and a pivot part 7 that is suspended by the rotating body 5 is disposed at the upper part of the left and right central parts of the front surface 10a and the rear surface 10b of the car body 10. Has been. The pivot 7 is constituted by a connecting shaft 7 a that protrudes outward (front and rear) from the front surface 10 a and the rear surface 10 b of the car body 10 and is suspended by the rotating body 5. That is, the connecting shaft 7 a is the same direction as the horizontal shaft 4. Therefore, the car 1 is suspended by the rotating body 5 at the pivotal support portion 7 so as to be swingable in the left-right direction that is the same as the traveling direction of the rotating body 5. Further, the front surface 10a of the car body 10 is a portion facing the platform 6, and an entrance 8 for a player to get on and off from the platform 6 is provided at the left and right central portions of the front surface 10a. At the lower edge of the mouth 8, a step 14 is provided to project forward in order to prevent the player from falling below the platform 6 when getting on and off. In addition, the car 1 is provided with windows 15 (left side 10d, right side 10e, front face 10a, and rear face 10b) around the car body 10 for the player to enjoy the scenery. In recent years, there are some which are provided with a slashing window on the lower surface 10f of the car body 10 so that the player can enjoy the thrill, and this can also be adopted. In the figure, 16 is a current collector for supplying power to the car 1, and 17 in the figure is a chair for a player sitting in a symmetrical manner inside the car body 10.

  And the automatic door 9 is employ | adopted as the entrance / exit 8 of the car 1 of this example. This automatic door 9 has a pair of doors 12 arranged at the entrance 8 and a door opening / closing mechanism 11 for opening and closing the doors 12, and drive control of the door opening / closing mechanism 11 by the control unit 20 (FIG. 12). Has been made to be done. A pair of doors 12 having the same shape and weight are used for the pair of doors 12, and each door 12 is attached to the car body 10 via arms 18 and 19 above and below the doors 12. Each arm 18, 19 is composed of a main arm 18 and a sub arm 19 that are shifted in pivot point to the door 12 and the car body 10, and the main arm 18 and the sub arm 19 are each of the car body 10. By pivoting around the pivot point, the door 12 can be opened by sliding along the front surface 10a of the car body 10 after the door 12 jumps forward from the entrance 8. Note that the main arm 18 positioned at the upper and lower portions of the car body 10 is connected to the car body 10 by connecting rods connected to each other by a connecting rod so as to be integrated with each other. The door opening / closing mechanism 11 is disposed in the left and right center part of the lower part of the car body 10 and is formed in a symmetrical structure. Specifically, as shown in FIGS. 5 to 7, the door opening / closing mechanism 11 includes a cylinder device 21 serving as a driving source, and left and right link devices 22 that convert the driving force of the cylinder device 21 into the opening / closing force of each door 12. It consists of Specifically, the cylinder device 21 is a device that drives the rod 21a to project and retract electrically, and is disposed at the left and right center portion of the lower portion of the car body 10 so that the rod 21a projects and retracts in the front-rear direction. Each link device 22 includes a V-shaped plate 23 having a base end portion pivotally supported by the car body 10 and a bifurcated tip end portion that can swing substantially horizontally. A first link rod 24 connected to one of the bifurcated tip portions of the character plate 23 by pin joining, a main gear 25 pivotally supported on the car body 10, and a tip portion on the main gear 25 The third link rod 27 whose base end portion is protruded from the main gear 25 with the base end fixed, and the base end portion is pin-joined to the other bifurcated distal end portion of the V-shaped plate 23 and the third link rod 27 A second link rod 26 having a distal end portion pin-joined to the base end portion of the car body 10 and a slave gear 28 attached to the pivotal support portion 7 of the car body 10 of the lower main arm 18 of the car body 10. And provided symmetrically at the left and right central portions of the lower portion of the car body 10. A base end of the sub arm 19 on the lower side of the car body 10 is pivotally supported in the vicinity of the outer edge of the main gear 25 so as to be rotatable.

  In the door opening / closing mechanism 11 having the above configuration, when the cylinder device 21 drives the rod 21a rearward, the first link rods 24 of the left and right link devices 22 are V-shaped plates as shown in FIGS. 23 is rotated rearward, and the second link rod 26 rotates the third end of the third link rod 27 around the distal end of the third link rod 27 as the V-plate 23 rotates rearward. The main gear 25 is rotated by the rotational movement of the third link rod 27, the slave gear 28 meshed with the main gear 25 is rotated, the main arm 18 is rotated in the opening direction, and the left and right doors 12 are moved. Each is designed to open. When the cylinder device 21 drives the rod 21a forward, the first link rods 24 of the left and right link devices 22 rotate the V-shaped plate 23 forward, as shown in FIGS. With the forward rotation of the character plate 23, the second link rod 26 rotates the third link rod 27 forward with the distal end of the third link rod 27 as the rotation center, and the third link rod 27 rotates. As a result, the main gear 25 rotates, and the slave gear 28 meshed with the main gear 25 rotates, so that the main arm 18 rotates in the closing direction, and the left and right doors 12 perform the closing operation. . The door opening / closing mechanism 11 having the above-described configuration is configured so that the cylinder device 21 and the left and right link devices 22 are configured symmetrically and operate symmetrically. Opening and closing operation is ensured.

  As described above, the door opening / closing mechanism 11 has a bilaterally symmetric structure, and the door opening / closing mechanism 11 is disposed at the center of the left and right sides of the car body 10, so that it swings in the left / right direction on the rotating body 5. A good weight balance in the left-right direction is ensured for the car 1 that is freely suspended. More specifically, the door opening / closing mechanism 11 is disposed at the lower part of the left and right center part of the car body 10 suspended from the rotating body 5 at the upper part of the left and right center part. The center of gravity can be located at a lower position of the vehicle, and the distance between the center of gravity and the suspended position from the rotating body 5 located at the top of the car 1 can be increased. Since the swing width around the hanging position of the car 1 can be reduced even when the car is added, a sense of stability is further provided in the weight balance in the left-right direction. In other words, the suspension posture with good balance can be secured to the car body 10 with a sense of stability. Further, the door opening / closing mechanism 11 having a symmetrical structure enables the pair of doors 12 to perform the opening / closing operation at the same timing. A pair of doors 12 that are beautiful and can feel a sense of stability and that open and close at the same timing are located at the same distance from the center of the left and right sides of the car body 10 during the opening and closing operation. A good weight balance in the left-right direction of the car 1 during operation is also ensured. In other words, when the door 12 is opened and closed (that is, when the player gets on and off the car 1), the player who gets on and off stands in the car 1, but at this time, the car 1 enters the car 1 as described above. Since a good left / right balance is ensured, the risk of a player standing up and down is reduced, and the player's safety for getting on and off is also improved.

  It should be noted that the second link rod 26 of the door opening / closing mechanism 11 of the present example is connected to the output door 12 of the cylinder device 21 when the door 12 receives a load from the door 12 side such as a person holding an obstacle such as a person. And a buffer mechanism 39 for buffering the load. Specifically, the buffer mechanism 39 is configured such that the second link rod 26 is formed to be extendable and contractable by a cylinder 26a and a rod 26b connected by a compression spring 26c. As a result, when a player is mistakenly sandwiched between the pair of doors 12, the load received by the door 12 moves the rod 26b against the cylinder 26a against the spring bias of the compression spring 26c as shown in FIG. Since the second link rod 26 contracts so that the third link 27 swings in the opening direction, the player is prevented from being caught by the door 12 with a strong force. In the meantime, the player can easily escape from between the pair of doors 12 sandwiched between them. Although the ratio of children is high as a player of the Ferris wheel A, the effect of preventing the player from being caught by the door 12 with the strong force described above is particularly effective in ensuring safety when the player is a child. Useful. Even when a player or the like is sandwiched between the pair of doors 12, the cylinder device 21 is normally operated so that the door 12 can be closed continuously when the player or the like is removed from between the pair of doors 12. However, the load received by the door 12 by the sandwiched object at this time is absorbed by the elastic deformation of the compression spring 26c, so that this load acts as stress on the link device 22 and the cylinder device 21. The service life of the automatic door 9 is also extended. Of course, when the sandwiched object is still sandwiched between the pair of doors 12, the cylinder device 21 is eventually overloaded, but the cylinder device 21 has a detecting means for detecting this overload. When the detection means detects an overload, the entire ferris wheel A is controlled to stop by the control unit 20 to ensure safety.

  By the way, the automatic door 9 is automatically opened and closed when the car 1 is positioned in the platform 6 by the control unit 20 provided in the car 1. Specifically, as shown in FIG. 8, detection portions 29 are respectively provided at end portions (left and right end portions) in the advancing direction on the rear surface 10 b (surface on the side not facing the platform 6) of the car body 10. Further, a detected portion 30 is provided at the facing position of the platform 6 across the entrance path of the car 1 in the vicinity of the entrance 6a to the platform 6 of the car 1, and the car 1 enters the platform 6 from the entrance 6a. The detected portion 30 is detected by both detection portions 29 of the car 1 to reliably detect that the car 1 is located in the platform 6, and the car 1 has surely entered the platform 6. In this state, the automatic door 9 is opened by the control unit 20, and when the car 1 exits from the exit 6 b of the platform 6, The controller 30 detects the vehicle 30 with the two detectors 29 of the car 1 and reliably detects that the car 1 is located outside the platform 6, and the controller 20 in a state in which the car 1 is reliably out of the platform 6. Thus, the automatic door 9 is closed. Here, a contactless sensor or the like using light or magnetic force can be adopted as the detection unit 29 or the detected unit 30, but in this example, as shown in FIGS. 8B and 8C, the car A rubber fin plate 32 that can be elastically deformed is attached to a pillar 31 that is erected on the side of one approach path, and the detected portion 30 is formed by projecting the fin plate 32 into the approach path of the car 1. And the detection part 29 which detects the contact of the said fin board 32 is employ | adopted, and the certainty of detection of the detection part 29 is expected. Specifically, the detection unit 29 includes a contact bar 29a that protrudes outward from the rear surface 10b of the car 1 and can be applied to the fin plate 32, and the contact bar 29a is placed on the protruding tip of the car 1. A roller 29b that can rotate in the traveling direction is provided, and the car 1 protrudes so as to be able to swing in the direction opposite to the traveling direction. When the fin plate 32 comes into contact with the fin plate 32, the fin plate 32 is made of rubber. Thus, the shock applied to the contact rod 29a can be buffered. As described above, when the car 1 enters the platform 6, the automatic door 9 of the entrance 8 can be automatically opened and closed. Therefore, this clerk can concentrate attention on the safety on the platform 6 and increase the safety of the Ferris wheel A. More specifically, the conventional clerk for opening and closing the door can be omitted, and labor saving of the Ferris wheel A is also achieved.

  The door opening / closing mechanism 11 can be manually operated from an emergency exit operating port 33 provided at the lower portion of the rear surface 10b of the car body 10. The emergency escape operation port 33 is provided with a lid that can be freely opened and closed. Although not shown, the automatic door 9 is provided with a door closing sensor that senses that the door 12 is in a closed state. When the car 1 exits from the outlet 6b of the platform 6, the door closing sensor is provided. When it is not confirmed that the door 12 is closed, the control unit 20 performs control such as stopping the operation of the Ferris wheel A. From this point of view, the safety of the Ferris wheel A is also improved. It is secured.

  Further, the car 1 of this example is provided with a lock device 34 that prevents the opening operation of the door 12 of the automatic door 9 that closes the entrance 8. Specifically, as shown in FIGS. 9 to 11, the lock device 34 includes a lock rod 36 that is slid upward by a solenoid 35 that is energized and energized, and a compression spring 37 that biases the lock rod 36 downward. Are arranged at symmetrical positions on the upper part of the car body 10. When the solenoid 35 is not energized, the lock rod 36 receives the bias of the compression spring 37 and is positioned adjacent to the opening rotation side of the main arm 18 at the top of the door 12 in the closed state as shown in FIG. Therefore, the main arm 18 cannot be turned in the opening direction when the automatic door 9 is in the closed state. Further, when the solenoid 35 is energized, the lock rod 36 is slid upwardly against the urging force of the compression spring 37, and is positioned adjacent to the opening rotation side of the main arm 18 of the upper portion of the door 12 in the closed state. Not to be. The lock device 34 is configured such that the solenoid 35 is energized when the car 1 enters the platform 6, and the energization of the solenoid 35 is released when the car 1 exits the platform 6. Is controlled by the control unit 20. In other words, the automatic door 9 is prevented from being opened in the car 1 exiting the platform 6 by the locking device 34, and the safety of the Ferris wheel A is ensured. Furthermore, the drive system of the lock device 34 is different from the drive system of the automatic door 9, and even if the cylinder device 21 of the automatic door 9 malfunctions, the lock device 34 can be reliably operated. Since the entrance / exit 8 can be kept closed by the door 12 of the automatic door 9, the safety of the Ferris wheel A is also improved in this respect. The locking device 34 can be manually operated from an emergency exit operating port 38 provided at the upper part of the front surface 10a of the Ferris wheel A. Specifically, the emergency escape operation port 38 is provided with a lid that can be opened and closed, and the lock rod 36 can be manually pulled up from the emergency escape operation port 38 by opening the lid. When the door 12 remains closed at the entrance / exit 8 in the event of an emergency such as a failure or a power failure, an operator manually pulls the lock rod 36 upward from the emergency exit operation port 38 on the platform 6 and performs an emergency exit operation. By manually operating the door opening / closing mechanism 11 from the port 33, the door 12 in the closed state at the entrance 8 can be manually opened.
