Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stationary small-sized amusement vehicle intended mainly for children such as infants, which is installed and used in amusement parks, the roofs of department stores, game corners, etc.

[Conventional technology]

Conventionally, there are various kinds of amusement rides as described above that operate for a certain period of time when a player inserts a predetermined coin to entertain the player. For example, there may be a car that can accommodate two children, a motorcycle, a train, a boat, an airplane, or an animal such as a horse.

By the way, all of these conventional small stationary amusement vehicles have simple movements, such as only moving back and forth, only moving up and down, only rotating, or only swinging like a seesaw. Many of them simply repeated one action, and few moved in multiple unusual ways. Even though the vehicle had a plurality of unusual movements, it was simple enough to use springs to amplify the vibrations caused when the vehicle itself moved back and forth, for example.

For this reason, in the above-mentioned small stationary amusement ride,
It has the advantage of allowing children to play with it easily at a low price, but on the other hand, because the movements are simple,
Today's children, who enjoy a variety of play activities, are unable to satisfy their playful spirit, and despite efforts to install such facilities, they are unpopular and are left unused due to the small number of users. .

For this reason, the present applicant has proposed that this kind of amusement vehicle has very interesting and complex movements in which the vehicle body, on which children and other players ride, moves back and forth and swings a lot at the same time. We are currently researching and developing something that will be extremely fun and satisfying.

As such an amusement vehicle, a trolley is provided so as to be movable back and forth along a guide such as a rail of a fixed frame, and the vehicle body is supported on the trolley so as to be swingable,
A configuration has been considered in which the vehicle body is largely rocked at the same time as the trolley is moved back and forth.

[Problem that the invention attempts to solve]

By the way, in the case where the truck moves back and forth and the vehicle body supported by the truck swings as described above, there is a concern that the drive device becomes complicated.

In other words, in conventional small stationary amusement vehicles of this type that only move forward and backward, a motor is provided outside the cart that can be moved back and forth, and the cart is driven back and forth by this external motor. many. If a vehicle with such a configuration is to be provided with the above-described swinging motion, a special motor for swinging motion is mounted on the trolley, and this motor is used to swing the vehicle body. There must be.

However, in such a configuration, it is necessary to provide a motor for longitudinal drive and a motor for rocking motion, and as the number of motors increases, the device becomes complicated.
There is a problem with high manufacturing costs.

The present invention uses only one motor, yet can drive the cart back and forth and drive the vehicle itself in a swinging manner.
The purpose is to provide an amusement vehicle with a simple configuration.

[Means for solving problems]

In the present invention, a trolley is provided so as to be able to reciprocate along the guide of the fixed frame, and a vehicle body on which a player can ride is swingably supported on the trolley, and a motor is mounted on the trolley. The front-rear drive crank arm and the rocking drive crank arm are connected so as to rotate, and a rod is spanned between the front-rear drive crank arm and the fixed frame to drive the truck back and forth, and the above-mentioned The present invention is characterized in that another rod is bridged between the rocking drive crank arm and the vehicle body to drive the vehicle body to rock.

[Effect]

According to the present invention, the rotation of the motor mounted on the truck drives the truck back and forth through the front and rear drive crank arms and rods, and the rotation of the motor drives the vehicle body through the swing drive crank arms and other rods. Since it is driven by swinging,
A single motor makes it possible to move the cart back and forth and swing the vehicle body. In this case, the motor is mounted on a cart that moves back and forth, which simplifies the configuration.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

1 in the figure is a stationary fixed frame, in which four columns 1b are erected on a rectangular base frame 1a constructed by welding multiple steel shapes, and horizontally mounted on these columns 1b. In this way, the left and right pair of guides 1
c and 1c are arranged horizontally. The left and right guides 1c, 1c each have a channel-shaped rail-like cross section that is elongated in the front-rear direction, and are opposed to each other with a parallel interval therebetween.

2 in the figure shows the left and right guides 1c inside the pedestal 1,
This is a trolley mounted so as to be able to move back and forth in the front and back direction along the line 1c. This bogie 2 has a generally rectangular underframe 2a constructed by welding a plurality of shaped steel members, and has a total of four wheel axles 3 protruding from each side, one pair at the front and one at the front. The guide wheel 5 rotatably attached via the left and right guide 1
c, 1c so that they slide and roll.

Here, a short prismatic body support 6 is erected from the center of the support beam 2b horizontally suspended between the underframe 2a of the truck 2, and swing shafts 7, 7 are provided on both sides of the body support 6. A body mounting plate 8 is provided horizontally protruding coaxially toward the left and right, and a body mounting plate 8 rotates a pair of left and right arms 8a, 8a, such as bearings, protruding from the lower surface of the body mounting plate 8. By fitting freely, they are attached so as to be swingable about the shafts 7, 7. A central bottom portion of the body of the vehicle body 9 is fixed to the upper surface of this body mounting plate 8. The vehicle main body 9 has a seat section on which multiple children can ride, and although a model imitating a boat is shown here, the vehicle body 9 is not limited to this, and may be used for various vehicles such as cars, trains, airplanes, etc. You may choose one that imitates or has an interesting shape that imitates an animal such as a horse, a horse such as a duck, or a fish such as a dolphin.

Further, a relatively narrow shelf-shaped base plate 12 is horizontally fixed to the underside of the underframe 2a of the truck 2 through angle members 10 and 11, two each hanging from the front and rear ends. A drive device 13 is mounted on the upper surface of the plate 12. This drive device 13 moves the trolley 2 back and forth and swings the vehicle body 9, and has a deceleration motor (geared motor) 14 attached to the rear end of the upper surface of the base plate 12 and a sprocket 15 of the motor shaft. It is comprised of a back-and-forth movement mechanism 17 and a swing mechanism 18 that are rotatably driven through a transmission chain 16.

The forward/rearward movement mechanism 17 is composed of a rotating shaft 20 supported on a pair of bearings 19, 19 fixedly mounted on the front end of the base plate 12, a sprocket 21 fitted onto one end of the rotating shaft 20 and around which the transmission chain 16 is wound, a crank arm 22 screwed to one side of the sprocket 21, a crank pin 23 protruding from one end of the crank arm 22, and a rod 25 having one end rotatably connected to the crank pin 23 and the other end rotatably connected to a fixed pin 24 on the inside of the front end pillar 1b of the fixed base 1.

On the other hand, the swinging mechanism 18 shares the rotating shaft 20 so as to be rotationally driven coaxially with the reciprocating mechanism 17, and includes a rotating plate (crank arm) 26 fitted to the other end of the rotating shaft 20; A crank pin 27 protrudes from the eccentric portion of the rotating plate 26, a lower end is rotatably connected to the crank pin 27, and an upper end is provided at a location slightly offset forward from the center of the lower surface of the mounting plate 8 of the vehicle body 9. The rod 29 is rotatably connected to the bracket 8b via a pin 28. In other words, both the reciprocating mechanism 17 and the swinging mechanism 18 are crank mechanisms that convert the rotation of the rotary shaft 20 driven by the motor 13 into reciprocating motion.

In the above-described amusement vehicle, when children get on the vehicle body 9 and insert a predetermined coin into the slot of a coin box (not shown), an electric switch is turned on and activated for a predetermined period of time. In this operation, the motor 14 of the drive device 13 rotates, and in conjunction with the motor 14 through the sprocket 15, transmission chain 16 and sprocket 21, the reciprocating mechanism 17 rotates at a constant speed in the direction of the arrow in FIG. As the crank arm 22 rotates together with the rotating shaft 20 and sprocket 21, the entire truck 2 moves horizontally back and forth along the left and right guides 1c, 1c of the frame 1 due to the crank action of the crank pin 23 and rod 25. Repeat the move. At this time, the vehicle body 9 supported on the truck 2 is also moved back and forth together with the truck 2. Also, during the back and forth movement, the rotating plate 26 of the swinging mechanism 18 rotates together with the rotating shaft 20, so that the crank pin 2
7 and the rod 29, the lower surface bracket 8b of the mounting plate 8 of the vehicle body 9 is moved up and down, and as a result, the vehicle body 9 is tilted forward greatly around the rocking shaft 7, or vice versa. It is made to oscillate in a downward slope.

In other words, the vehicle main body 9 moves forward from the intermediate position shown in the figure and enters an upwardly tilted state, and then moves backward from the forward limit of its movement, corrects itself to a horizontal state, returns to the initial intermediate position, and then returns to the initial intermediate position. While moving further backwards, the vehicle tilts forward downward (backward upward), moves forward from the backward limit, corrects itself to a horizontal position, returns to the intermediate position, and moves forward again, and so on. By combining two types of movements: forward and backward movement, and the rocking of the pitching, which goes up and down, the children are able to move in a variety of interesting movements that were not found in the past. You can enjoy it and enjoy it more.

Although not shown, the fixed pedestal 1 is entirely covered with a cover that has elongated holes formed on the top surface through which the body holder 6 and the rod 29 can move, thereby ensuring safety and improving the appearance. In addition to improving the appearance of the vehicle, it also has a decorative effect that matches the upper vehicle body 9. Also, during the above operation, music (back music) that matches the movement and the shape of the vehicle body 9 is played.

[Effect of idea]

As explained above, according to the present invention, the rotation of the motor mounted on the truck drives the truck back and forth via the front and rear drive crank arm and the rod, and the rotation of the motor drives the swing drive crank arm and other rods. Since the vehicle body is driven to swing through the rod, it is possible to move the truck back and forth and swing the vehicle body using a single motor. In this case, since the motor is mounted on a cart that moves back and forth, the power for the back and forth drive and swing drive can be immediately branched off from this motor, simplifying the structure. Since it can be attached to a trolley, it can be made smaller and more compact, and it can also be made cheaper. By not incorporating a drive device into the vehicle body, there are advantages such as the vehicle body being able to be used as a passenger seat without waste, and an enjoyable vehicle to be obtained.
