TOY TRACK SYSTEM SUMMARY OFTHE INVENTION This invention relates to a toy and more particularly to a new and useful toy railroad or track system comprising. in combination, a domed continuous track and an electric motor-driven toy vehicle, The railroad is arranged in such a way that an electric motor-dirven toy vehicle is adapted to run on a pair of conductive rail members disposed within a transparent dome or semicylindrical housing, said rail members being electrically connected to an electric control box.
A number of toy railroads or track systems have heretofore been proposed. Most of these are usually constructed such that an electrically operated train or vehicle is adapted to run on a more conventional track, such as a pair of conductive rails which is exposed to view. Therefore, they have, in general. the disadvantages of being monotonous in appearance and lacking in attractiveness. it is also pointed put that it is difficult to effect a satisfactory electrical connection between the conductive rail sections and also that the rail sections themselves are difficult to connect.
It is, therefore, one object of the present invention to provide entertainment and amusement for children by avoiding such disadvantages and providing a novel and useful toy electric railroad or track system in which an electric motor-driven toy vehicle runs on a pair of continuous conductive rail members which are disposed inside a transparent or translucent tunnellilte cover so that the vehicle travelling therethrough can be viewed from the outside through such cover.
it is another object of the present invention is to provide a new and useful toy of the kind stated above which comprises an electrically operated toy vehicle having a miniature bulb emitting light rays, and a transparent or translucent tunnellike cover having a conductive track on which the vehicle is adapted to run, said tunncllilte cover or dome having means for rcfracting and/or reflecting the light rays emitted by said bulb so that the light rays will be diffused in various directions, as the vehicle runs through the continuous dome, to thereby increase socallcd "play value" of the toy.
It is further object of the present invention to provide a new and useful toy electric railroad or track system of the character described above which comprises different shapes of domed electrical rails which can be easily connected together to form any desired shape of a continuous track and which can be perfectly electrically connected to each other.
it is still further object of the present invention to provide a new toy railroad or track system of the type set forth above which comprises supporting members and accessory members for use in the formation of a new elevated railroad of modern type.
It is yct another object of the present invention to provide a new toy railroad or track system in which the travelling of an electric motondrivcn toy vehicle can be remotely controlled by manual operation of an electric control box.
The features of the present invention which are believed to be novel are act forth with particularity in the appended claims.

The current controlled regulated by the variable resistance which controls the voltage is led to output terminals (not shown) which are connected to lead wires 24 and 24 which are provided with nippers 25 and 25 at the foremost ends thereof, respectively.
The semicylindrical dome track sections 1, 2 and 3 are connected to each other in the following manner. First, two of the track sections are held close to each other edgewise, each being held at an angle of about 45 as illustrated in FIG. 5, and they are brought closer to each other until the small hole 7' of one of the track sections comes to the position of the lateral projection 6' of the other of said track sections, and also until the small hole 10 is positioned to the lateral projection 9'. Then, these lateral projections 6 and 9' are inserted in the small holes 7' and 10', respectively. Thereafter, these two track sections are swung relative to each other about the lateral projections 6 and 9' serving as the fulcrums until these two track sections are aligned straight relative to each other at the end portions of joint of these two track sections. As a result, the aforesaid lugs 6 and 9 will fit in said recesses 8 and 11, while on the other hand the contact cars 13 and 13 of the conductive rails 12a and 12b, after said lugs 6 and 9 have thus been firmly contacted by said contact ears 13 and 13, are brought into tight contact with the contact ears 14 and 14 which are located side by side with said protrusions 7 and 10. In this way, these two track sections are coupled firmly to each other. Accordingly, the conductive rails 12a and 12b of one of said track sections will be brought in tight contact with the corresponding conductive rails 12a and 12b of the other of the two track sections to produce a positive, electrical connection therebetween. It is to be noted that these dome track sections which constitute the railroad track B can be coupled together without the need of any excessive force such as the force with which to broaden the distance between the inner faces of the lugs 6 and 9, and this fact eliminates the danger that the lateral projections 6' and 9' or other members and elements of the track sections are broken.
After the track sections 1, 2 and 3 and the supporting pedestals 16 have been fabricated into an assembly in the manner described above, the input terminals 15a and 1511 which are connected to the conductive rails 12a and 12b of one of said track sections of the track B are nipped by said nippers 25 and 25 to electrically connect the conductive rails 12a and 12b to said control box C. Thereafter, the aforesaid knob 23 of the control box C is turned to close the electric circuit. Whereupon, electric current is allowed to flow through the series circuit formed between the conductive rails 12a and 12b and the motor 17 and the miniature electric bulb 19 of said vehicle A. As a result, the miniature electric bulb 19 is lighted on and at the same time the motor is actuated. The power of this motor is transmitted, through said pinion and said crown gear, to the mile 17 to drive the wheels 18 and 18. In this way, the vehicle A with its miniature electric bulb 19 being lighted on is caused to run on the conductive rails 12a and 12b. It is to be noted that during this travel of the vehicle A, the speed of the running vehicle A and the intensity of brightness of the light of the miniature bulb 19 can be freely controlled as desired by the manual operation of the operating knob 23.
As has been stated, the toy railroad or track system of the present invention is formed by combining, in an appropriate manner, several different kinds of individual transparent dome track sections to each other, each being of the same arrangement with the only exception that they are either curved, straight or inclined to produce said several different kinds. Therefore, a variety of an overhead type cross railroad circuits may be easily fabricated by the use of a desired number of the track sections and the supporting pedestals. In addition, the light rays which are emitted from the miniature electric bulb which is provided in the vehicle adapted to run through the tunnel will be refracted and reflected in various directions during the travel of the vehicle by the transparent dome track, especially by the lens portions and the surfaces of the grooves provided on and in semicylindrical dome. Therefore, the patterns of the light rays which are diffused in various directions as the vehicle runs through the continuous tunnel will lead to the advantage that a greatly enjoyable toy is obtained. Furthermore, the unique arrangement of the toy of the present invention has made it possible to effect a satisfactory electric connection between the conductive rails which has been considered extremely difficult. The disposition of the conductive rails within the track sections in such a way as to be integral with the latter permits the manufacture of the aforesaid respective kinds of track sections at a low cost. Also, to use ornamental accessory members such, for example, as seen on the tops of the toy assembly illustrated in FIG. 1 will increase the attractiveness of the toy. Furthermore, by giving an appropriate color or colors to the individual track sections, there will be obtained a beautiful toy as a whole, and what is more, the effect of the diffusion of light described above will be all the more enhanced. it is needless to say that by the use of a plurality of the toy sets of the present invention, they can be utilized also as a unique and novel racing car set.
It should be noted that the principles of the present invention may be applied to different types of toy track systems and that the devices of the present invention, as heretofore stated, may be used in combination with any suitable track system.
While the particular toy herein shown and described in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiment of the invention and that no limitations are intended to the details of construction or design herein shown other than as defined in the appended claims.
