DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a straddling monorail type traveling toy.

[0002]

2. Description of the Related Art There are many types of traveling toys with a railway motif, and there are many variations. The power source is usually electric power, and usually employs a method in which a motor is used to move driving wheels to travel along a fixed track (rail). The power to the motor is generally supplied from a battery in a relatively inexpensive toy. When collecting electricity from the track, it is necessary to provide a current collecting path along the track, and when the track connects several elements, both mechanical connection and electrical connection are required Because. Lines made of conductive metal, which were once commercially available, are suitable for two-wire and three-wire rails, and are not suitable for monorail types that require a structure that bears strength. Not suitable.

[0003] The linear motor car has been in the limelight, for example, with the construction of an experimental line progressing and the practical use route being planned. However, currently known vehicles have an appearance similar to a straddle type monorail type. Therefore, when a linear motor car is planned as a monorail-type traveling toy, a method of supplying electric power to the motor becomes a problem in addition to the above-described problems. This is because when the batteries are loaded into the vehicle, the center of gravity rises, and the monorail type is unstable, so measures need to be taken. However, a traveling toy of the above type has not yet been proposed.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to make it possible for a straddle-type monorail traveling toy to travel stably and to ensure a reliable and easy rail. Is to be able to connect.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a driving vehicle which can travel by a driving wheel having an upper surface of a projected rail as a traveling path and a free wheel rolling on the traveling path. comprises, together with the movably journalled to the vehicle width direction to drive the vehicle a pair of left and right current collecting wheel that rotates in contact with a current path provided on both left and right sides of the railway, the same collector wheel to current paths A means is provided in which a pressing elastic means is provided in the drive vehicle as a part of the current collecting circuit. In addition, the rail has a male-female fitting type connection part, and there is a current collecting path on the male outer surface and the female side inner surface of the connecting part, and a means is adopted that the current collecting path is connected at the same time as the male and female fitting. .

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A traveling toy according to the present invention is a straddle-type monorail traveling toy. Therefore, this traveling toy has a monorail type rail 10 and a vehicle for traveling there, and the vehicle is a combination of a driving vehicle A having a self-propelled function and a vehicle B having no self-propelled function. Can be.

[0007] The rail 10 is a base 1 placed on a laying surface such as a floor.
1 and a monorail structure projecting therefrom and having an upper surface serving as a traveling path 12. A current collecting path 13 is provided on one or both of the left and right sides of the rail 10 (FIGS. 5 and 6). The upper part of the rail provided with the traveling path 12 has an end 14 projecting left and right beyond the current collecting path 13. See FIG.

The rail 10 has a structure that can be disassembled, cleared, and assembled at the time of use. Therefore, at the end of each rail 10, there are male and female mating connection parts 15, 16,
Extends to each connection. See FIG. Connection parts 15, 16
In this embodiment, the base 11 and the traveling path 12 are formed so as to protrude or retract in a staggered manner, and the monorail intermediate portion 17 is fitted between the upper traveling path 12 and the lower base lower plate 18. Reference numeral 19 denotes a member for stabilizing the rail.

[0009] To further explain the electric system,
A current is sent to the current collector 13 from a power box, that is, a controller 20. The control unit 20 includes a power source (not shown) such as a battery or a converter for converting a home power source to DC, a switch 22 interposed in a wiring circuit 21 to the current collecting path 13, and a variable resistor for adjusting the traveling speed. Adjuster 23 like vessel
And so on.

The rail 10 has several elements such as a linear element and a curved element as shown in the drawing, and the elements are connected to each other by a connecting portion 24 to assemble a desired layout.
See FIG. Of course, in addition to the above elements, a branch element, an intersection element, and the like can be used together.

A driving vehicle A having driving wheels 25 traveling on the traveling path 12 and free wheels 26 rolling on the traveling path 12 is combined with the rail 10 as traveling wheels. The driving vehicle A is set on the rail 10 in a straddling manner, and is driven by an electric motor 27 provided therein.
The vehicle travels on drive wheels 25 driven via power transmission means 28 such as a gear set.

In order to collect power from the rail 10, a current collecting wheel 29 rotating in contact with a current collecting path 13 provided on a side surface of the rail 10 is moved to a driving vehicle A simulating a linear motor car in a vehicle width direction. An elastic means 30 is provided in the driving vehicle A as a part of a current collecting circuit, which is movably supported and pushes the current collecting wheel 29 toward the current collecting path 13. See FIGS. By elastically pressing the pair of current collecting wheels 29 against the current collecting paths 13 on both the left and right sides, the driving vehicle A is elastically held on the rail 10 and stability is enhanced. In addition, since the battery is not disposed in the vehicle, the position of the center of gravity of the driving vehicle A does not need to be raised, and light driving can be achieved by reducing the weight.

In the illustrated example, the collector wheel 29 is supported by upper and lower shafts 31 and 32 having a large diameter at the center like an abacus ball. At least a part of the upper and lower shafts 31 and 32 (particularly, the upper portion 31 in the drawing) is supported by a bearing 33 having a long hole in the vehicle width direction, and is configured so that the elastic force of the elastic means 30 is sufficiently transmitted. I have. See FIG. 5 (b). The illustrated elastic means 30 is made of a metal piece having a spring property, and forms a part of a wiring for supplying electric power to the motor 27 by slidingly contacting a part of the current collecting wheel 29.

To improve the stability in the left-right direction, the rail 10
A guide wheel 34 is provided on the vehicle body as a pair of left and right or more free wheels in contact with a part of the vehicle body. The drive wheel 25, the free wheel 26, the guide wheel 34 and the like are covered by a skirt 35. Further, a guide portion 36 extending forward can be provided in order to avoid contact with a structure or the like that can appear on the rail 10 such as a branch portion or to smooth the direction of the traveling course.

A connecting portion 37 of the driving vehicle A is provided at an end near the driving wheel 25 for connection with the vehicle B having no self-propelling function. On the other hand, the free wheel 26 can be provided at an end other than the connecting portion 37 side. However, the driving vehicle A may have the connecting portions 37 at both ends, and may be the driving wheels 25 for both front and rear traveling wheels.

In connection with the vehicle B having no self-propelled function,
It can be configured such that the load of another vehicle B connected at the connection portion is applied to the drive wheels 25. This is driving vehicle A
This is achieved by applying a load on the other vehicle B side by setting the connection joint 38 on the side of the vehicle B to be lower and the connection joint 39 on the side of another vehicle B to be higher. In the illustrated example simulating a linear motor car, one connecting joint 38 has a vertical shaft, and the other connecting joint 39 has a hole that fits coaxially.

The other vehicle B is provided with a weight 40 for applying a load to the connecting portion 37. Due to this load, the connected vehicle B comes to follow the vehicle stably even at high speed. The connected vehicle B having no self-propelled function can support one end of the vehicle body by the connecting portion 37, and therefore can run if the free wheel 26 is provided only at the other end of the vehicle body. However, the guide wheel 3 is used as a free wheel for stability in the left-right direction.
Needless to say, 4 can be provided. Reference numeral 41 denotes a connecting portion cover, and reference numeral 42 denotes a space where the connecting portion cover 41 can enter.

Therefore, necessary rail elements are connected at the connecting portion 24 to form a fixed running track layout. Before the last rail 10 is connected, the traveling toys vehicles A and B
It is better to set it to straddle type 2. However, collector wheel 2
9 has a flat spindle shape such as an abacus ball, and can be retracted outward by the elastic means 30, so that the vehicles A and B can be set and removed from the upper side after the rail is completed.

In the case of a bidirectional switch, when the lever is tilted to either side, the power distribution circuit 21 is energized and the current collecting circuit is also activated. That is, if sufficient electric power is selected by the adjuster 23, the vehicles A and B start running at a speed corresponding to the value, accelerate, decelerate, and stop.

[0020]

Since the present invention is constructed and operates as described above, the electrical connection of the current collecting path is made by the mechanical connection of the rail elements, so that the vehicle does not need a power source battery, and the center of gravity is reduced. Do not raise, the pair of left and right collector wheels are rails
Since taking system in contact with the left and right sides of the current paths to the resilient, reliable current collecting effect can be obtained, and also because the vehicle body resiliency by elastic contact is obtained, enabling stable traveling This has the effect.
