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.

Dependent claims

An accessible pedestrian pushbutton station mountable to a vertical support surface, the pushbutton station comprising:

a housing having a front and a back;
a push button assembly supported in the front of the housing,
a rear mount having a rear surface attachable to the vertical support surface and a front surface with a first pivot surface;
a second pivot surface fixed to the back of the pushbutton station housing and formed for pivotal attachment to the first pivot surface on the rear mount whereby the pushbutton station housing is supported for pivotal movement relative to the rear mount about a vertical axis;
and
a pair of vertical sidewalls extending from the front surface of the rear mount to at least partially define a rear mount cavity;
a pair of vertical sidewalls extending from the back of the pushbutton station housing to at least partial define a housing back cavity;
and
wherein the pair of vertical sidewalls of one of the rear mount cavity and the housing back cavity fits telescopically with the pair of vertical sidewalk of the other of the rear mount cavity and the housing back cavity.
