Y s, claims. (criss- 19) i My invention relates to improvements in safety zone devices', and it consists of the com` binations, constructions and arrangements hereinafter described and claimed.
'An object of my invention is to provide a safety zone device which takes the place of a number of buttons and is designed to extend entirely across an end of a safety zone. The device makes' use of a number of removable glass panels that are disposed in a single plane and are designed to reflect the light from the headlights of approaching vehicles. The mirrored glasses may be colored in any desired manner forfurther attracting attention,Vv and the. end glass may be disposed at an angle of forty-five degrees if desired so as to reect light at right angles.v The glasses are pro-'- tected against accidental breakage.Y
The device extends across one end of the safety.v zone for vtwo purposes,v .the first is tol prevent. vehicles moving onto the zone, andthe second is to provide an illuminated line coeX- tensive with the line of the end zone. The device is preferably made-.of aluminum so as to be light in weight and is cast in a single piece. The device is simple in construction and is constructed so as to withstand heavy Weights.
Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawing forming a part of this application, in which Figure 1 is a front elevation of the device;
Figure 2 is a top plan View;
Figure 3 is an enlarged horizontal section through a portion of the device;
Figure 4 is a transverse section enlarged; and
Figure 5 is a horizontal section through a modified form of the device.
In carrying out my invention, I provide a casting indicated generally at I, which is long enough to extend across the Width of a safety zone and thus do away with the necessity of providing a plurality of buttons. The casting is preferably made of aluminum so as to be light in weight and has a base portion 2, (see Figure 4), with an upwardly-extending wall 3. An overhanging portion 4 is integral With the wall 3 and cooperates with a projecting foot portion 5 for providing an elongated recess 6 for receiving removable reflectors hereinafter described. The ends of the casting I are'provided with protecting vslallswl that' pre1-.j
ject in iront of the wall 3. I y
-A curved wall '8 extends'fromthe overhanging portionr 4- to the rear of the base 2f, and this c-urvedwall is supported at intervals by vertically-extending,"'integral webs' Si.V The base 2 has an opening I0 thereinz and thek Opening denes an inwardly-fextending flangeA Il.
'A'number o freflectors fareY placed in the recessgl and are secured'to thewall 3 by brackprisesfa flat glass lcolored in anyY suitable place. lf'fdesired,'the back'surface of the glass I3 may be silvered soA as to provide a reflectingA surface. The wallv 3 hasfa vertically-extending groove I5 therein ,forjreceiving the bracketv I2, and the bracket'is heloljfinV place .DY/.means ofy a screw' H),l or' other suitable fastening means. Thev bracket has laterally-projectingl portions I8', for" reflectorsrare held in place;
I have shown five reflectors in Figures 1 and 2, although this number may be Varied Without departing from the spirit and scope of the invention. In case one of the reflectors becomes accidentally broken, the pieces of glassV are held in place by means of the frame I4. A new reector can be substituted for the broken one by merely removing the bracket I2.
The wall portion 5 has a centrally-disposed lug I9, (see Figures 2 and 4) and this lug removably receives a fastening bolt 2!) that is used for securing the device to the pavement. The lug I9 has a portion projecting below the base 2, as `shown in Figure 4, and this portion is received in a recess in the pavement. The ends of the casting I are held in place by fastening members, such as bolts 2|. The elongated reflector is designed to show as an illuminated line when reflecting light rays from the headlights of an approaching automobile, and this line is coextensive with the line defining an end of the safety zone. Also the device prevents a vehicle from driving through the safety zone.
In Figure 5, I show a slightly-modified form of the device. This form is identical vto that described, except that a reflector 22 is disposed at a forty-live degree angle to the reflectors I3. This causes light rays striking the reflector 22 to be projected at an angle of ninety degrees. This type of reflector can be used for Warning pedestrians on the sidewalk as they are about engag ng-with the frames'l-Iland in this-way, 'the to make their VWay to the Asafety zone. j An approaching vehicle will illuminate the reflector 22, and the pedestrian will be warned in this Y Y n e struction across the entire'end of the safety manner. l Y Y VWhileY I'have shown only the preferred forms of myinvention, it should be understood that various changes or modifications maybe made 'Y ing an elongated` frame extendingracro'ss the Y Y' within the Vscope of the'appended claimsjwithendof'asafetyarea and includinga sustaining out departing from the I claim:
l. A Vsafety zone indicating Vdevice compris- 'ing an elongated'frame extending acrossl ,the
