From California in the 1950s, "Fifth Wheel" to simplify parallel parking and garage entry

In cars equipped with functions to support garage parking in parallel parking or back with an alarm of contact prevention alarm using a camera at the rear of the body and a sound wave sensor, and vehicles that automatically do steering until some are not uncommon recently Perhaps it is a car with a unique parking assist function completely different in ideas from those, but devised in California in the 1950s about 60 years ago from now.

The movie in which "5th wheel" which is normally hidden demonstrates power is from the following.YouTube - 1950's Fifth Wheel Parking Concept


While the car gets bigger, the parking space is getting smaller. So CaliforniaPiedmontAn inventor who invented a device that solves the driver's headache.


Switch on and demonstrate at once.


A seemingly ordinary spare tire that entered the trunk.


When I descend under the car body ......


I will lift the rear wheel as it is.


Drive shaftWith this "fifth tire" connected to this, you can escape with enough margin, even if you have enough parallel parking that you can not get out unless you have to move the front and rear cars.


After putting the rear part of the car body to the road so as to make it swing, it is OK if you retract "5th tire" as it is.


This car seems to be Cadillac, but this device named "Park car" by the inventor is that it can be installed in any car.


Next, demonstration of garage parking. Even though I wanted to put in a garage in the back when considering the way out, if the road to the garage is narrow and long, is not there many people who are anxious to go back at the entrance of the driveway all the time?


In such a case as well, it thrusts from the head until a little before the garage ......


If there is the same road width as the length of the car, you can change direction by 180 degrees.



Very smooth. In a place like this garage where there are garages for several cars at the end of a narrow driveway, it seems to be optimal as the radius of gyration can be secured before the garage.
