Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an entertainment track-traveling vehicle device mainly for children, which is installed on the roof of an amusement park, a department store, or an event plaza.

(Prior Art) A roller coaster is known as a rail running game device installed in an amusement park, and it has been popularly operated. However, the conventional roller coaster running in an amusement park is a recreational vehicle that pulls a vehicle on which a passenger rides to a high place and then coasts to a low place, which has long rails and large ups and downs. ,
People who can ride this must be of a certain height or above, and small children and young children must not.

As a rail running game device for small children and toddlers, a mini-vehicle that can run on a circular or elliptical orbit by itself is known. However, conventional mini trains and the like have little or no height difference in their tracks, and since the turning track is a simple circle or elliptical track, they tend to lack interest.

For this reason, there is a demand for an entertainment railroad vehicle in which children or infants and mothers can feel as if they were riding a roller coaster on which adults are riding.

(Problems to be solved by the invention) For small children and toddlers, a mini type coaster of extremely small scale is desired, and in order to make it a roller coaster, it is necessary to provide up and down tracks. However, it is feared that setting a large up / down or increasing the running speed will scare small children and young children and may be dangerous, so the coasting method like a roller coaster will increase the running speed. However, since it is difficult to control the speed, a track traveling device with a small change in speed is required, and a drive traveling system that can control traveling at low speed is desirable.

In addition, in order to enjoy it at a small expense and with little expense, it is desirable to reduce the size of the entire device and the area of the facility.

Under such conditions, when studying a miniature railroad traveling vehicle device for children, it is desired that the up-down radius of curvature and the radius of curvature of the curved portion are small, and the vehicle can travel on a track with a small radius of curvature. And have to.

In this case, when either the left or right wheel of the front wheels or the rear wheels is used as the driving wheel, there is a difference in the speed of turning the curve between the right turn and the left turn, and when turning the curve part with a small radius of curvature. There is a concern that the speed will suddenly increase and a large centrifugal force will be generated, increasing the risk.

In the present invention, the rail having a relatively small installation area and a small radius of curvature of the up and down and the radius of curvature of the curve can be traveled with a simple structure, and the speed can be increased at the up and down at the curve. It is an object of the present invention to provide a railroad traveling vehicle device which can maintain a low speed running without change, is highly safe, and can run on a variety of courses despite being enjoyed by small children and young children.

(Means for Solving the Problem) The present invention is a rail running game vehicle apparatus for allowing a vehicle equipped with a drive device to self-propell along a rail, wherein the rail is
The rail is composed of a pair of left and right guide rails and a drive rail arranged in the middle of the pair of left and right guide rails, following the guide rails. The vehicle is an endless course including a downhill portion and a curved portion, and the vehicle has a bogie frame, projecting pins provided at the bottom of the bogie frame on the center line of the vehicle traveling direction and at positions separated from each other in the traveling direction, and the front and rear protrusions thereof. Arms that are pivotally supported by pins and extend in the left-right direction and can rotate horizontally, main wheels that are provided at both ends of the front and rear arms and that can roll on the upper surface of the guide rail, and the lower surface of the guide rail. A lower wheel for preventing floating of a movable vehicle and a horizontal wheel rotatably disposed on the inner or outer side or both inner and outer sides of the guide rail,
The drive device includes a drive motor supported on the bogie frame, and a drive wheel that is rotated by the drive motor and is located on the vehicle traveling direction center line of the bogie frame and rolls on the upper surface of the drive rail. An urging member for urging the drive wheel so as to be pressed against the upper surface of the drive rail.

(Operation) According to the present invention, since the track is an endless course having a straight track part, an uphill and a downhill part, and a curved part, the running path is rich in variation, and the vehicle has front and rear protrusions at the bottom of the bogie frame. It has horizontally rotating arms that are pivotally supported via pins and extend in the left-right direction. The main wheels are provided at both ends of these arms and can roll on the upper surface of the guide rail, and roll on the lower surface of the guide rail. Since it has a lower wheel that prevents possible vehicle lift and horizontal wheels that can be rolled on the inside or outside or both inside and outside of the guide rail, the longitudinal direction of each arm is always perpendicular to the guide rail. Since the main wheel is always directly above the guide rail, even a curved part with a small radius of curvature can travel without removing the wheel. Furthermore, avoid a coasting means that may increase the traveling speed, and use a vehicle equipped with a drive device such as a reduction motor, and the drive wheels are located on the center line of the bogie frame in the vehicle traveling direction. Since the upper surface is rotatively contacted, it is possible to turn at the same speed when turning the curve to the right and left, and it is safe without sudden centrifugal force. Since the driving wheel is pressed against the upper surface of the driving rail by the biasing member,
The structure of the drive system can be simplified.

It is driven via a chain 67 that is stretched between 62 and 66.

The lower ends of the tension springs 71 and 72 are connected to the front end of the pedestal 50, and the upper ends of these springs 71 and 72 are attached to the cross member 8b. The tensile strength of the tension springs 71, 72 can be adjusted by the adjusting nut 73.

Such a pedestal 50 has tension springs 71,72 at the front end.
Since the urging force in the pulling direction is received by and the load of the reduction motor 61 provided at the rear end acts, the urging force is urged counterclockwise in FIG. 3 about the pin portions 52 and 53 as fulcrums. Therefore, the tire 63 is pushed downward and pressed against the upper surface of the drive rail 3. Therefore, when the drive reduction motor 61 is rotated, the tire 63 is forcibly rotated via the chain 67,
The tire 63 causes friction between the tire 63 and the driving rail 3 and thus drives the vehicle forward.

In this case, the mounting position of the tire 63 is, as is clear from FIG. 2, installed at the center of the vehicle in the front-rear direction and the left-right direction. Therefore, the drive rail 3 is provided on the traveling locus of the tire 63 between the guide rails 2 and 2.

 The operation of the embodiment having such a configuration will be described.

When the driving deceleration motor 61 is driven, the tire 63 is forcibly rotated via the chain 67, and the tire 63 causes friction with the driving rail 3 to rotate and travel on the driving rail 3 surface. Therefore, the vehicle 6 is driven forward.

The running track is a straight track section 1a, an uphill section 1b, and a downhill section 1c.
・ Because the curved parts 1d and 1e are formed, you can enjoy different driving compared to conventional mini trains.

In order for small children and toddlers to enjoy with a small expense, it is desirable that the installation site area of the entire device is small, and therefore the radius of curvature of the curved track must be made small. As the structure of the vehicle traveling 1e, arms 14 and 22 pivotably supported at front and rear positions on the center line of the bogie frame 11 in the traveling direction are provided.
Main wheels 33L, 33R and 34L, 34R are provided at both ends of these arms 14, 22, respectively, and a lower wheel 39 for preventing floating and horizontal wheels 35R, 36R, 35L, 36L, 37R, 38R, 37L, 38L are provided. Therefore, the longitudinal directions of the arms 14 and 22 are always kept at right angles to the guide rails 2 and 2, and therefore, the respective main wheels
The 33L, 33R and 34L, 34R never come off the guide rails 2, 2.

Therefore, the vehicle can smoothly travel even in a curved portion having a small radius of curvature.

In addition, floating prevention lower wheels 39 ...
Since the vehicle 6 is provided, the vehicle 6 is prevented from being lifted up, and the vehicle 6 is stably held even on an up / down course.

Then, the tire driven by the drive reduction motor 61
Since the 63 is pressed against the upper surface of the drive rail 3 by the urging force of the tension springs 71 and 72, a large frictional resistance is generated between the tire 63 and the drive rail 3, and therefore slippage occurs even on an uphill track. The passenger can easily climb up and run without getting up, and the structure of the drive device can be extremely simplified.

In this case, since the mounting position of the tire 63 is installed at the center of the vehicle in the front-rear direction and the left-right direction as is clear from FIG. 2, the same speed is applied in both the right turn and the left turn. The vehicle can be advanced. For this reason, it is possible to prevent a problem that the centrifugal force is generated due to a sudden change in speed at the curved portion.

Further, the main wheels 33L, 33R and 34L, 34R, the lifting prevention lower wheel 39 ... and the horizontal wheels 35R, 36R, 35L, 36L, 37R, 38
Since the R, 37L, and 38L all rotate via ball bearings, it is possible to travel with little resistance when the vehicle travels.

In the above embodiment, the horizontal wheels 35, 36, 37, 38 are provided at the front and rear in pairs at the ends of the arms 14, 22, respectively, so that they roll on the inner surface of the guide rail 2. These may roll on the outer surface of the guide rail 2, or one of the pair may roll on the inner surface of the guide rail 2 and the other roll on the outer surface of the guide rail 2.

(Effects of the Invention) As described above, according to the present invention, the straight line portion on the track,
Since the uphill, downhill and curved sections are provided, children and toddlers in the vehicle can feel the same as riding on a roller coaster for adults and enjoy the fun. In addition, the vehicle is safe because the main wheels, the lift-up lower wheels, and the horizontal wheels prevent derailment and overturning, and can smoothly travel even on a curve with a small radius of curvature. Therefore, the orbiting vehicle device can be a small-sized device, and therefore can be installed in a relatively narrow place. Furthermore, since the drive wheels are installed in the center of the vehicle in the front-rear direction and the left-right direction, it is possible to advance the vehicle at the same speed in both right turn and left turn, and the speed suddenly increases at the curve. Problems such as changes and generation of centrifugal force are prevented. As a result, speed changes can be made small despite the presence of uphill sections, downhill sections, and curved sections, so that infants will not be scared, and children will be safe and enjoyable. Orbital play vehicles for mothers and infants. Can be provided.
