Abstract

An accessible pedestrian pushbutton station. The station includes an articulating rear mounting structure to facilitate accurate positioning of the station on either a curved or flat surface. Additionally, slots in the rear mounting structure allow for minor positional adjustments during installation. The crossing direction arrow is easily repositioned on the front of the station without disassembling the housing. After removing the screw-mounted arrow, the plunger can be turned clockwise or counter-clockwise using only a flat-head screw driver. The plunger is balanced between oppositely biased springs. The spring-balanced plunger indirectly actuates an offset piezo bender using a flexible spring actuator and a second, offset stem bumper. This protects the piezo bender from direct pressure and potential damage. The station includes an internal speaker and the housing includes bilateral sound vents to project the sound emitted by the speaker. Baffles may be inserted in one or both of the sound vents.

Claims10

Dependent claims

An accessible pedestrian pushbutton station comprising:

a housing having a front that includes a plunger space;
a push button assembly supported in the housing, the pushbutton assembly comprising:
a plunger with a plunger head having a front and a rear;
at least one detent on the rear of the plunger head;
wherein the plunger space in the front of the housing is sized to receive the plunger head and includes at least one detent receiving notch;
wherein the plunger is mounted in the housing for axial and rotational movement between a fixed position and an adjustment position,
wherein in the fixed position, the at least one detent on the rear of the plunger head is received in the at least one detent receiving notch in the plunger space so that rotation without axial movement is prevented, and wherein in the adjustment position, the at least one detent is withdrawn from the at least one detent receiving notch so that rotation of the plunger head is permitted;
a spring assembly for axially biasing the plunger inwardly toward the housing;
and
a crossing direction arrow removably attached to the front of the plunger.
