A toy train and trackway wherein the trackway is provided with a section which has a base and upstanding side walls provided with supporting surfaces which include portions that are parallel to the base and portions that slope downwardly toward the base, a powered vehicle having wheels that move along the trackway and the base of the section and which is provided with outwardly extending flanges, and a plurality of covers of varying configuration for the vehicle, each being provided with flanges extending outwardly therefrom which are oriented to engage the supporting surfaces of the side walls of the section and the flanges of the vehicle.

Description

BACKGROUND AND SUMMARY OF THE INVENTION

The present invention relates to the general class of toys wherein a powered vehicle traverses a trackway. More particularly, the trackway of the present invention is provided with a station section which includes upstanding walls provided with supporting surfaces that are parallel to the base and then slope downwardly toward the base. The powered vehicle has wheels which move along the trackway, and flanges which extend outwardly from the sides thereof. A plurality of covers of varying configuration are designed to both slide along the station section and to fit over the vehicle. To accomplish the foregoing, each of the covers is provided with flanges which extend outwardly therefrom and which are positioned apart from each other a distance such that the flanges engage the supporting surfaces of the sidewalls of the trackway and as well the flanges of the vehicle. Thus, as the vehicle enters the station section the cover carried thereby is deposited on the supporting surfaces of the upstanding walls of the station section, afterwhich the powered vehicle moves under the intermediate cover, and then engages the last cover which is positioned along the downwardly sloping supporting surfaces thereafter carrying this cover around the trackway, afterwhich this procedure is repeated time and time again for each of the covers.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The amusement device of the present invention, as illustrated in FIG. 1, consists of a trackway having a turning section 10, a straight section 12, a station section 14, a turn around section 16, an elevated section 18, and a bridge section 20. Appropriate wall structure generally designated by the

reference numerals

22, 24, 26, 28, 30, 32, 34, 36, 38, 40, and 42 is provided within the

sections

10, 12, 16, 18, and 20 to define a continuous path along which a powered vehicle 44 travels.

As illustrated in FIG. 5, the vehicle 44 consists of a chassis 46 through which a shaft 48 extends to which the front wheels 50 are mounted such that the wheels 50 are free to rotate as the vehicle 46 moves along the trackway. A miniature motor, which may be battery powered or of the wind-up variety, well known in the prior art, is enclosed within the chassis 46 and arranged to drive the rear wheels 52 which are mounted to an axle 54 extending through the chassis 46. The top of the chassis 46 is provided with an upstanding central portion 58 having a front beveled surface 60, and side portions 62, each of which includes a front beveled surface 64.

Three or more vehicle casings designated by the

reference numerals

66, 68, and 70, as illustrated in FIGS. 6-8, are constructed to fit on top of the powered vehicle 44. The vehicle casing 66 is designed to resemble a high speed train engine, the vehicle casing 68 is designed to resemble an electric engine, and the vehicle casing 70 is designed to resemble a wood burning engine.

It will be apparent that each of the

vehicle casings

66, 68, and 70 are provided with outwardly extending flanges 72 which are constructed to rest upon the corresponding flanges 74 which extend outwardly from the top of the chassis 46 of the powered vehicle 44.

The station section 14 consists of a base 76 along which the vehicle 44 travels, and

sidewalls

78 and 80 which extend upwardly from the base 76 and which include on the insides thereof shoulders provided with supporting surfaces 82 which are spaced apart from each other such that the flanges 72 of the

vehicle casings

66, 68, and 70 may rest upon the surfaces 82. It can be seen from FIGS. 1 and 3 that the supporting surfaces 82 terminate in surfaces 82' that slope downwardly in the vicinity of the station house 84 which is positioned at the end of the section 14.

As illustrated in FIG. 2, the section 20 is provided with a bridge 86 which is mounted to rotate about a shaft 88 which is journalled within the section 20, and a spring 90, having one end fastened to an abutment 92 on the section 20 and the other end thereof attached to a flange 94 extending from the bridge 88, which normally urges the bridge 86 into raised position.

As illustrated in FIGS. 1 and 9, the turning section 10 is provided at the center thereof with an upstanding post 96 having a spiral groove formed therein defining a supporting surface 98. Affixed to the left front wheel 50 of the powered vehicle 44 is a cam 100 provided with a stepped surface 102 ending in a tip as shown. The interrelationship between the tip of cam 100 and the surface 98 of the spiral groove on the post 96 will be explained hereinafter.

After the

vehicle casings

66, 68 and 70 are positioned along the supporting surfaces 82 of the station section 14, the motor within the vehicle 44 is activated causing the vehicle 44 to move forwardly along the trackway. Eventually, the

beveled surfaces

60 and 64 of the vehicle 44 strike the rear wall 104 of the first of the vehicle casings that are lined up on the station section 14. As illustrated in FIG. 3, for example, engagement of the

beveled surfaces

60 and 64 against the rear wall 104 of the vehicle casing 68 permits the vehicle 44 to raise the casing 68 upwardly and thereafter move under the casing 68, afterwhich the

beveled surfaces

60 and 64 engage the rear wall 104 of the vehicle casing 66 raising momentarily the casing 66 to permit the vehicle 44 to continue its movement along the section 14. Eventually, the vehicle 44 reaches the last casing 64 which is resting in a downwardly inclined position on the supporting surfaces 82'. Note that abutments 106 that are formed at the end of the

walls

78 and 82 engage the front ends of the side flanges 72 which extend outwardly from the vehicle casings for retaining the

respective casings

66, 68 and 70 in position as the vehicle 44 moves forwardly along the station section 14. Eventually, the front portions 75 of the flanges 74 of the forward vehicle 44 engage the downwardly extending flanges 108 and the vehicle 44 is positioned within the vehicle casing 70, raising the vehicle casing 70 and the flanges 72 above the abutments 106 of the

walls

78 and 80 thus permitting the vehicle 44 with the casing 70 positioned thereon to leave the station section 14, as illustrated in FIG. 4.Iadd.. .Iaddend..[.of.]. .Iadd.Of .Iaddend.course the abutments 106 must be of such a height to permit this action to take place. The vehicle 44 then carries the casing 70 around the trackway and eventually deposits same at the rear of the station section 14, afterwhich the procedure enumerated above is repeated. Thus, each time the vehicle 44 approaches the station 14 it deposits a casing that it has carried onto the front end of the station 14, at which time the flanges 72 extending outwardly from the casing rest on the supporting surfaces 82 of the

walls

78 and 80. The vehicle 44 continues to move underneath the remainder of the casings until reaching the last of the casings which has its flanges 72 resting on the downwardly inclined supporting surfaces 82', at which time the vehicle 44 engages this last casing and carries same along the trackway.

Of course, for the above operation to function as described the distance A between base 76 and the portions 82 of the supporting surfaces of the

sidewalls

78, 80 that are parallel to the base is greater than the distance between the bottoms of

wheels

50, 52 and flanges 74 of the powered vehicle 44 such that when the vehicle and the respective covers are in that portion of the station section wherein the supporting surfaces 82 are parallel to the base 76, the flanges 74 of the vehicle are positioned below the flanges 72 of the cover.

The front of vehicle 44 is provided with

beveled surfaces

60, 64 such that as the vehicle travels along the station section the beveled surfaces engage the covers that are resting on the portions 82 of the supporting surfaces that are parallel to the base raising the respective covers in turn as the vehicle passes underneath thereof.

Abutments 106 are formed at the ends of the portions 82' of the supporting surfaces that slope downwardly for engaging the front ends of flanges 72 of the respective covers. The distance B between the ends of portions 82' of the supporting surfaces that slope downwardly and the base is less than the distance X between the bottom of

wheels

50, 52 and the flanges 74 of the powered vehicle such that when the vehicle is at the end of station section 14 the flanges of the vehicle engage the flanges 72 of the associated cover raising same above abutments 106 and permitting the vehicle and cover to leave the station section.

From FIGS. 1 and 2, it will be apparent that as the vehicle 44 enters the section 20 the bridge 86 is lowered by the weight of the vehicle 44 against the force of the spring 90. After the vehicle 44 leaves the section 20 the bridge 86 rises once again. Thereafter, the vehicle 44 enters the turning section 10, at which time the cam 100 on the left front wheel 50 engages the post 96. The engagement of the cam 100 and the post 96 causes the vehicle 44 to circle the post 96 during which time the tip of surface 102 of the cam 100 rises along the supporting surface 98 of the spiral groove on the 96. When the tip of surface 102 of the cam 100 reaching the uppermost part of the supporting surface 98, the cam 100 is released from the post 96 thus permitting the vehicle to leave the turning section 10 to enter the section 12.

Of course, the cam 100 is suitably spaced from the left front wheel 50 of the powered vehicle 44 so that the wheel will not engage or bind on post 96 as the vehicle circles around post 96 when the vehicle is in the turning section 10.
