Description
1323~6~
~AC~C~oUND OF T~E INYENTION
The present invention relates to a housing for a switch, and more particularly relates to a housing for a switch for pedestrian crossing lights which are mounted at a pedestrian crosswalk along a roadway.
Particularly in large urban centers, at locations along roadways other than intersections, there may be specially marked pedestrian crosswalks. At these crosswalks, there may be lights, actuable by a pedestrian intendlng to cross the roadway at such location, and visible by drivers of vehicles in the vicinity of the pedestrian crosswalk, requiring such drivers to stop their vehicles while the lights are actuated and thereby permit safe passage of the pedestrian across the roadway by way of such crosswalk. Conventionally, such lights are positioned over the roadway above the crosswalk, and the switches for operating such lights are mounted on poles, which may be conventional light standards, on either side of the roadway in the vicinity of the commencement of the crosswalk.
In this way the switches are convenient to a pedestrian wishing to traverse the roadway on such crosswalk. Usually such switches are associated with a timing means so that the crosswalk lights are activated only for a period of time sufficient to enable a pedestrian to cross the crosswalk.
Switches are also used at pedestrian crosswalks at signalized intersections to change the sequence of the signal , 1323~65 displays when a pedestrian wishes to cross, as well as sometimes to activate audible indications for sight impaired pedestrians.
There are several different types of conventional switches used to activate such pedestrian crosswalk lights.
Many of such switches have housings made of metal, with many metal component parts which often times seize and make them difficult to disassemble for servicing. As well, metal housings have been known to transmit shocks to users when the circuitry or switches within have broken down. Because the switches are intended to operate in an outdoor environment, they are subject to rigorous use and, occasionally, to vandalism. The switches themselves are usually actuated by depressing a button switch, and it is highly desirable that such button switch be easy to operate even for persons wearing gloves or having limited finger mobility.
It is therefore an object of the present invention to provide a housing for a pedestrian crossing light switch which i will be easy to install and operate, as well as to remove for purposes of servicing. It is a further object of the present invention to provide such a housing for a switch which will minimize the opportunity for vandalism. It is yet a further object of the present invention to provide such a housing which will permit the switch to operate even under rigorous climatic conditions, with relative safety for a pedestrian user.

SUMMARY OF THE INVE~TION
In accordance with the invention there is provided a housing for a switch, such as a pedestrian crossing light switch, which is normally pole-mounted in an exterior environment and intended for public use. The housing has a body made of sturdy plastic of integral construction. The body comprises side walls with an end wall at one end thereof, forming a chamber open at the other end thereof. The end wall mountably receives the switch internally within the chamber as well as an indicator lamp, which is illuminated when the pedestrian crossing light is actuated, where such indicator lamp is included. Flange means outwardly extend from the open end, and the flange means are curved to mateably receive a portion of a pole on which the housing is mounted.
In a preferred embodiment of the present invention the side walls are of cylindrical shape. The flange means comprise flanges, portions of which extend upwardly and downwardly from the open end of the cylindrical sides in a direction normal to their axis. A pair of spaced, strap receiving ridges are provided on the upper and lower flange portions, and extend transversely from side-to-side across the flange portions. Each pair of the strap receiving ridges receive therebetween a metal band to be wrapped about that flange portion and a pole for securing the housing at a desired position on a pole. Gasket means are secured about the .: :, - ; ~ . ~:.
: :, :
13~30~
periphery of the flanges on their pole-receiving surfaces to seal the chamber, when the housing is mounted on a pole, against external weather conditions.
The housing in accordance with the present invention is extremely easy to install, requiring only the application of bands to circumscribe the flanges and the pole to which the housing is to be mounted. Because it is made of plastic, the chance a pedestrian user may receive an electrical shock when activating the switch is virtually eliminated. The integral construction and unique shape of the housing make it possible to attach the component parts such as the switch internally, and secure the parts internally against vandalism. A
pedestrian light switch mounted within a housing in accordance with the present invention is reliable and easy to operate in all types of weather.

DETAILED DESCRIPTION OF T~E DRAWINGS
In the drawings, similar features have been given similar reference numerals.
~ urning to FIGURE 1, there is illustrated a pedestrian crossing light switch housing 2 in accordance with the present invention, mounted by means of circumscribing bands 4 on a service pole 6.
As can be seen in the drawings, the housing comprises a portion having side walls 10, of cylindrical form, with an end wall shown generally as 12, at one end thereof with the side walls 10 being open at the other end (FIGURE 4). At the base of cylindrical walls 10 are flanges 14 curved about an axis normal to the axis of the cylindrical sides 10 as illustrated so as to conform to the surface of pole 6 on which housing 2 is mounted. Upper and lower flange portions 16 and 18 are each provided respectively with pairs of spaced band-retaining ridges 20, within which metal bands 4 are seated when wrapped about housing 2 and pole 4 to hold the housing in position. As can be seen in FIGURE 3, appropriate weatherproofing gasket material 22 is provided about the periphery of the interior surface of flanges 14 so that, when housing 2 is mounted on pole 4, the interior thereof, and in particular interior chamber 24 within cylindrical ~alls 10, is sealed from external environmental weather conditions.
As can be seen in FIGURES 2, 3 and 4, end wall 12 of housing 2 takes a form of a series of stepped surfaces starting from a lower, circular, centrally positioned base surface 26, and progressing outwardly to a spaced annular support surface 28 and an exterior annular circumscribing surface 30. The function of each of these surfaces will be described in more detail hereinafter.
The housing of the general shape as described previously herein is preferably made from an appropriate molded plastic such as ABS plastic, which is both durable and rugged (to resist the effects of weather and vandalism). It is preferably made in a readily visible colour, such as yellow.
A housing 2 of this shape permits easy assemblage of the components of the pedestrian crossing light switch, which ,~.

components include micro switch 32, neon lamp 34, actuator button 36, nylon reinforced rubber diaphragm 38 and actuator cover 40. Micro switch 32, having wires 41 leading to pedestrian crossing light circuitry (not illustrated) is mounted internally, within chamber 24 (FIGURE 4) to end base 26, and secured thereto by appropriate securing means such as bolt 44 extending through aperture 42 in end base 26, and nut 44 which threadably engages bolt 40 on the exterior side of end base 26 to secure micro switch 32 in position. Micro switch 32 preferably is a single-pole momentary action micro switch such as, for example, a Burgess QVCFT9 (trade mark) micro switch.
Double~pole switches can be used where, it is desired to control more functions than just switching lights. Micro switch 32 is actuated by means of actuator button 36 having post 46 seated in an appropriate socket in bolt 44 therein, actuator button 36 being positioned on the exterior side of end base 26 wîthin the well formed by circumscribing side step surfaces 48 (FI~URE 4). A coil spring 47 is preferably positioned between end base 26 and the back of actuator button 36, so as to urge actuator button 36 outwardly, back to its normal, inoperative position, after it has been depressed to actuate micro switch 32. This additional bias provided by spring 47 is important to ensure proper return of actuator button 36, for example in extremely cold weather when the resiliency of rubber 38 or the smooth mechanical operation of actuator button 36 with respect to micro switch 32 may be , .. , . . ~ .
restricted. Neon lamp 34, which is seatably and visibly secured on support surface 28, is wired into the circuitry of the pedestrian crossing lights and micro switch 32 such that it is visibly acuated before the pedestrian crossing lights are on, to give a visual indication to a pedestrian that a demand has been registered by the light switching electronics to switch the pedestrian crossing lights on. Actuator button 36 preferably has an enlarged surface as illustrated, to facilitate actuation thereof by, for example, the young, the elderly, or persons wearing gloves.
To minimize the effects of inclement weather on the workings of micro switch 32 and actuator button 36, nylon reinforced rubber diaphragm 38 is positioned over actuator button 36, and secured in position thereby by means of actuator cover 40, actuator cover 40 and diaphragm 38 being secured in position on annular support surface 28 by means of internally fastened screws 50. Because of the outward and sideways stepped construction of the surfaces of end wall 12, it can be seen (EIGURE 4) that the mounting of micro switch 32 and the securing of actuator cover 40 and diaphragm 38 in position by means of screws 50 may be readily achieved from within chamber 24. As a further feature to reduce the opportunity for vandalism (e.g. by the jamming of a knife or other object between side wall 46 and actuator button 36), the inner diameter of annular actuator cover 40 is preferably such that the space between side wall 48 and actuator button 36 is - .. : . ;. .. . .

The housing and push button switch for a pedestrian crosswalk, as described above, provides an easy to install and repair, as well as easy to operate system for activating pedestrian crosswalk lights. Because the working and electrical parts are completely encased within housing 2, the effects of inclement conditions, such as freezing rain on the system are minimized. As well, because of the internal mounting of the components of the system within chamber 24, and the durable construction of the housing, the system is extremely difficult to vandalize. The large, concentrically placed actuator button 36 is also very easy to locate and operate for pedestrians.
Thus it is apparent that there has been provided in accordance with the invention a housing for pedestrian crossing signal switches that fully satisfies the objects, aims and advantages set forth above. While the invention has been described in conjunction with a specific embodiment thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications and variations as fall within the spirit and broad scope of the invention.
