Abstract

Abstract A toy vehicle racing game is described utilizing a continuous, unguided vehicle race track with steeply banked curves and straight, flat horizontal track sections. The width of the unguided roadbed surface is selected so that vehicles may pass one another. A player-controlled chicane is employed in the path of the high speed vehicles. The chicane includes normally active slow-down devices which the players attempt to disable manually just at the time that their vehicle is about to pass over the chicane. Vehicles which are able to pass the chicane without a speed reduction travel over the high end of the steeply banked curves to pass other vehicles which were slowed down. A vehicle diverter is employed to segregate the vehicles on a right-left basis before traversing the chicane. The vehicle diverter employs track guides in dove-tailed relationship to guide the vehicles and prevent their bouncing off the track as they engage the track guides at high speeds. The toy vehicles are spring-driven and provided with travel range limits to require a number of spring rewinds before completing a race of a desired number of laps around the track.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 184 words
A toy vehicle track segment comprising a vehicle racing surface and means on said segment for co-acting with a surface on a vehicle to brake the vehicle while retaining it vertically, said means including first and second elongated braking elements projecting upwardly from said racing surface, said first braking element having a vehicle contacting surface which is inclined at an acute angle relative to the vehicle racing surface to form therewith a recess to receive a complementary-shaped vehicle-mounted guide to direct toy vehicles traversing the vehicle racing surface while maintaining the toy vehicle in operative contact with the vehicle racing surface; said second braking element having a vehicle-contacting surface that is inclined at an acute angle to the vehicle racing surface, said contacting surfaces of said first and second braking elements being located in spaced opposed relationship to frictionally engage a vehicle-mounted guide therebetween, said second braking element being movably mounted to the track segment for braking movement towards and away from the first braking element to influence the speed of a toy vehicle whose guide passes between the first and second braking elements.
Claim 2
Dependent Claim 184 words
A toy vehicle track segment comprising a vehicle racing surface and means on said segment for co-acting with a surface on a vehicle to brake the vehicle while retaining it vertically, said means including first and second elongated braking elements projecting upwardly from said racing surface, said first braking element having a vehicle contacting surface which is inclined at an acute angle relative to the vehicle racing surface to form therewith a recess to receive a complementary-shaped vehicle-mounted guide to direct toy vehicles traversing the vehicle racing surface while maintaining the toy vehicle in operative contact with the vehicle racing surface; said second braking element having a vehicle-contacting surface that is inclined at an acute angle to the vehicle racing surface, said contacting surfaces of said first and second braking elements being located in spaced opposed relationship to frictionally engage a vehicle-mounted guide therebetween, said second braking element being movably mounted to the track segment for braking movement towards and away from the first braking element to influence the speed of a toy vehicle whose guide passes between the first and second braking elements.
Claim 3
Dependent Claim 31 words
The toy vehicle track segment as in claim 1 further including means for momentarily actuating said second braking element to cause successive movements towards and away from the first braking element.
Claim 4
Dependent Claim 47 words
The toy vehicle track segment as in claim 2 wherein said momentary actuating means further includes: a normally-contracted bellows operatively coupled to the second braking element to cause movement thereof in response to expansion of the bellows; and means for pressurizing said bellows to cause expansion thereof.
Claim 5
Dependent Claim 31 words
The toy vehicle track segment as in claim 3 wherein said momentary actuating means further includes means effectively coupled to the bellows to spring bias said bellows to a contracted state.
Claim 6
Dependent Claim 36 words
The toy vehicle track segment as in claim 4 further including means for varying said spring bias to vary the braking force applied to said vehicle when frictionally engaged by said first and second braking elements.
Claim 7
Dependent Claim 36 words
The toy vehicle track segment as in claim 5 wherein said bellows has a bleed hole which is sized to cause recovery to the normally contracted state of the bellows over a predetermined period of time.
