Abstract
Abstract A traffic indicator used in the road has a body movable from an indicating position to a protection position, the body including a first shoulder lying substantially flush with the road surface, and thus in the protecting position, and a second shoulder, having a reflector in it, standing at an angle away from the first shoulder above the road surface and thus residing in the indicating position. A stationary bar extends through the body for supporting it in a recess in the roadway. The bar forms an axle about which the body pivotally moves from the indicating to the protecting position. A spring means is disposed in the body so that the indicator will be urged back to the indicating position after a vehicle has passed over it and caused it to pivot to the protecting position.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
205 words
A traffic indicator used in a road, comprising: a body movable from an indicating position to a protecting position having a first shoulder which lies substantially flush with the road surface in the indicating position and a second shoulder extending at an angle away from the first shoulder to a location above the road surface in the indicating position; a reflecting element visible to drivers of vehicles moving along the road surface provided on the second shoulder of said body; a stationary bar extending through a passageway in said body for supporting said body in the road with the first shoulder substantially flush with the road surface in the indicating position, said bar extending substantially transverse to the direction of vehicular travel along the road and forming an axis about which said body pivotally moves from the indicating position to the protecting position; a tab extending from and held stationary with said bar; spring means disposed between said body and said tab for urging said body into the indicating position; a moving vehicle engaging said body will thus cause the body to pivot to the protecting position and the spring means will return the body to the indicating position after the vehicle passes the indicator.
Claim 2
Dependent Claim
205 words
A traffic indicator used in a road, comprising: a body movable from an indicating position to a protecting position having a first shoulder which lies substantially flush with the road surface in the indicating position and a second shoulder extending at an angle away from the first shoulder to a location above the road surface in the indicating position; a reflecting element visible to drivers of vehicles moving along the road surface provided on the second shoulder of said body; a stationary bar extending through a passageway in said body for supporting said body in the road with the first shoulder substantially flush with the road surface in the indicating position, said bar extending substantially transverse to the direction of vehicular travel along the road and forming an axis about which said body pivotally moves from the indicating position to the protecting position; a tab extending from and held stationary with said bar; spring means disposed between said body and said tab for urging said body into the indicating position; a moving vehicle engaging said body will thus cause the body to pivot to the protecting position and the spring means will return the body to the indicating position after the vehicle passes the indicator.
Claim 3
Dependent Claim
58 words
The indicator of claim 1, wherein said tab and spring means are disposed within the passageway; including side plates attached on each side of said body, each plate having an opening through which said bar extends; and a seal disposed across the passage of material into the passageway which might interfere with the pivotal action of said body.
Claim 4
Dependent Claim
38 words
The indicator of claim 2, wherein a recess is provided within the second shoulder of said body and the reflector is disposed within the recess to further inhibit the possibility of damage to the reflector from moving vehicles.
Claim 5
Dependent Claim
30 words
The indicator of claim 3, wherein the second surface extends from the first surface at a location past the pivotal axis from the direction the moving vehicles approach said body.
Claim 6
Dependent Claim
136 words
In a reflector body adapted to be recessed into a roadway and to be pivotally mounted therein to move from a first operative position to a second protected position when a vehicle passes thereover so that no damage occurs from contact with the vehicle comprising: a pair of side walls, each having an arcuate defining edge greater than 180° and two radial edges extending to the arcuate edge from a central point thereof, a surface wall connecting the said arcuate defining edges, and a reflector means disposed between at least one pair of opposing radial edges of said side walls, and an axle means perpendicular to said side walls for pivotally supporting the body in the roadway so that contact of vehicle with either radial edges causes the body to pivot to one of said positions.
Claim 7
Dependent Claim
136 words
In a reflector body adapted to be recessed into a roadway and to be pivotally mounted therein to move from a first operative position to a second protected position when a vehicle passes thereover so that no damage occurs from contact with the vehicle comprising: a pair of side walls, each having an arcuate defining edge greater than 180° and two radial edges extending to the arcuate edge from a central point thereof, a surface wall connecting the said arcuate defining edges, and a reflector means disposed between at least one pair of opposing radial edges of said side walls, and an axle means perpendicular to said side walls for pivotally supporting the body in the roadway so that contact of vehicle with either radial edges causes the body to pivot to one of said positions.
Claim 8
Dependent Claim
33 words
The reflector body of claim 5 wherein a bias means is disposed in operative relationship to the reflector body to urge the reflector means to a position above the surface of the roadway.
Claim 9
Dependent Claim
58 words
The reflector body of claim 6 wherein the bias means includes a tab extending from the axle for abutting engagement by a spring means, and a spring means for contacting the tab to urge the reflector body toward its operative position but having sufficient resilience to permit movement of the body to the recessed position in the roadway.
Claim 10
Dependent Claim
77 words
A reflector body of semi-circular configuration adapted to be embedded in a roadway but to protrude there above having a reflector on a radially disposed surface and supported on a stationary axle mounted through the center so as to move in pivotal manner thereabout when it is contacted by a passing vehicle, and biasing means disposed in operative relation to the reflector body to urge the reflector body to a position above the surface of the roadway.
Claim 11
Dependent Claim
77 words
A reflector body of semi-circular configuration adapted to be embedded in a roadway but to protrude there above having a reflector on a radially disposed surface and supported on a stationary axle mounted through the center so as to move in pivotal manner thereabout when it is contacted by a passing vehicle, and biasing means disposed in operative relation to the reflector body to urge the reflector body to a position above the surface of the roadway.
