Continuous Roadbeds Patents (Class 238/10C)
  • Patent number: 6164555
    Abstract: A structure is provided for creating an elevated subroadbed for an artificial landscape. The structure includes a flexible riser section of a given length that has a generally planar bottom. The riser section also has a generally planar top extending and supported parallel to the bottom so that the height of the section is consistent along its entire length. The riser is provided with first and second side walls, which each have a series of channels that extend into the riser in spaced apart relation. The channels allow the riser to be positioned in a radius. The top forms an elevated surface that enables low-lying areas to be more easily created on the artificial landscape below the elevated surface.

  • Patent number: 5839657
    Abstract: A method is provided for creating an incline for a roadbed on an artificial landscape that involves coupling a flexible section to a base in a desired location. The section has a top that extends at an angle relative to its bottom so that it increases in elevation from one end to the other. The section has a series of channels formed therein which allows the section to flex so that it can conform to a curve. The method further involves placing a second section in abutting relationship with the first section to form a roadbed with a continuously increasing or decreasing grade. In one embodiment, the method further includes placing a number of flexible sections in abutting relationship to form an incline that rises from a base to a desired elevation. The present invention also provides a flexible section for creating a roadbed for an artificial landscape. The section has a top that extends at an angle relative to its bottom so that the section increases in elevation from one end to the other.

  • Patent number: 5299969
    Abstract: A loop feature for propelled toy vehicles includes a generally vertically oriented single loop having a movable ingress portion and a movable egress portion. A propelled toy vehicle enters the loop upon engaging one surface of the ingress portion. Player-operable controls effect movement of the egress portion to permit the propelled toy vehicle to exit the loop. Both movable portions have a free end and a connected end. The connected end of each movable portion is hingedly connected to each end of a fixed arcuate portion. Within the loop there is provision for propelling the toy vehicle as it continues to go around the loop.

  • Patent number: 5203733
    Abstract: Die-cut corrugated paperboard blanks define a closed looped oval race track. The blanks form a flat roadway surface which is supported on paperboard wedges at an angle to provide banked straightaways and curves for the travel thereon of radio controlled battery powered cars. A paperboard barrier formed of a plurality of folded corrugated blanks is engaged against the elevated edges of the roadway to prevent the escape of the cars from the race track. The blanks which form the banked curves of the roadway have a plurality of radial slit scores which facilitate the bending of the corrugated paperboard blanks to approximate a frustroconical shape.

  • Patent number: 4195776
    Abstract: A track section for model vehicles adapted to be interconnected with like adjacent track sections includes a longitudinally extending body having a top wall, first and second end faces and first and second sides. First and second teeth extend transversely from the body proximate the sides and the end faces in transversely opposite directions away from the centers of the end faces. First and second receiving members are fixed relative to the body proximate the sides and the end faces, each receiving member defining a recess adapted to receive a corresponding tooth of a like adjacent track section. First and second transverse flexion stabilizing members project longitudinally outward relative to the respective first and second receiving members. First and second lugs are mounted to the sides of the body proximate the teeth, each lug defining a cavity adapted to receive a corresponding transverse flexion stabilizing member of a like adjacent track section.

  • Patent number: 4106694
    Abstract: A railroad bed assembly for supporting thereon metallic railroad tracks is formed with a base structure which consists essentially of reinforced concrete made as prefabricated blocks with the base structure including a slab section adapted to be installed over a ground formation at the railroad bed site and with at least one upwardly extending projection running transversely to the direction of the tracks and having a trapezoidal cross sectional configuration taken in a plane extending parallel to the tracks. The projection and the slab are integrally formed of prestressed concrete material and the projection extends to form a cross tie for supporting thereupon the tracks.

  • Patent number: 4091561
    Abstract: A toy road system includes a helical, ascending roadway fixedly mounted on a base and coaxially enveloping a column rotatably mounted on the same base. A slide is axially freely movable on the column, but secured thereto for joint angular movement. A permanent magnet on the slide may couple a toy vehicle carrying an armature to the slide so that the slide rises along the column and a coupled vehicle moves along the ascending roadway while the column turns. A descending roadway connects the two ends of the helical roadway for descent of the uncoupled vehicle by gravity.

  • Patent number: 4082220
    Abstract: A sectional track construction wherein each section constitutes a generally flat body having at least one longitudinally extending conductor exposed upwardly and provided with end portions each extending beyond the adjacent lateral body portion on one side of the conductor, and an oblique cam at each end of the section for engagement with a like cam of a like section to urge the exposed conductor end portions into side-by-side facing engagement with conductor end portions of a like track section.
