Curb feeler mounted behind the front wheel of a 1950s Rambler American.

Curb feelers or curb finders are springs or wires installed on a vehicle which act as "whiskers" to warn drivers that they are too close to the curb or other obstruction. The devices are fitted low on the body, close to the wheels. As the vehicle approaches the curb, the protruding 'feelers act as whiskers and scrape against the curb making a noise and alerting the driver in time to avoid damaging the wheels or hubcaps. Since they are flexible, they bend out of the way when pressed against a surface.[1] The original Rambler was an automobile produced of the Thomas B. Jeffery Company then by its successor, Nash-Kelvinator Corporation and finally, by its successor, American Motors Corporation (all in Kenosha, Wisconsin). ...

Hotrods

Curb feelers are still used on some hotrods when a 1950s look is wanted. They are especially popular for cars with whitewall tires which easily lose their white coating when scraped against the curb. Sometimes curb feelers are found only on the passenger side of the car since that is most commonly near the curb when parking. Sometimes they are added only next to the front wheels. Some curb feelers have a single wire or spring - others have two to increase the area that can be protected. A particular car might have between one and eight 'feelers.

Rec vehicles

Recreational vehicles sometimes have rubber feelers or metal antenna rods mounted on the lower part of the body that act as 'feelers so that drivers are warned if they are approaching a curb or other obstruction, thus reducing the chances of gouging or even cutting the tire sidewalls and generally increasing the safety of vehicle operation.

Heavy equipment

Today, the U.S. Department of Labor Mine Safety and Health Administration mentions that users of heavy equipment can benefit from an analagous accesory: The United States Department of Labor is a Cabinet department of the United States government responsible for occupational safety, wage and hour standards, unemployment insurance benefits, re-employment services, and some economic statistics. ...

In the 1950's, cars were often equipped with curb feelers ...Using a piece of 48 inch conveyor belt, 4 to 5 feet long by 4 to 6 inches wide and a couple of pieces of angle iron, you can make a pinch-point feeler, a warning device for the corners of a continuous miner. This will give a warning nudge to anyone in the danger area, giving him or her about a two-foot running start to stop the machine or to yell at the operator to stop. The belting is stiff enough to hold its shape but flexible enough to give if it runs into a miner or vice versa. The flexibility also allows this "curb feeler" to drag against the rib or be smacked by a shuttle car with little or no damage. A little spray from a can of reflective paint will make the belt a visual warning device as well. One or two on each corner will help or put as many as you want.[2] Belting is the substantive derived from the verb to Belt, and hence has the same heterogenous meanings. ...

Although different in design from the whisker-like feelers described above, the purpose of these devices is same.


Electronic sensors

Curb feelers based on optical technology are designed to function the same way but work in the proximity of an obstruction rather than having to come into physical contact with it. As described by one United States patent: The United States patent law is a first-to-invent patent legal framework in contrast to all other national patent laws. ...

An electronic curb feeler system uses two pairs of optical sensor units to detect an object located near the front end of a vehicle during parking. One pair of optical sensor units detects an object directly in front of a left portion of the front end of the vehicle while another pair of optical sensors detects an object directly in front of a right portion of the front end of the vehicle. By supplying the operator of the vehicle with the location of the object as well as the exact distance the object is from the front end of the vehicle the operator can avoid hitting the object while parking very close to the object.[5]

Devices such as this, and simpler electronic devices similar to the original wire curb feelers used on cars, are used in the design of various mobile robotic devices. One robotics company that does work for the United States Department of Defense uses laser-assisted curb feeler technology.[6] It has been suggested that this article or section be merged with robot. ...
