Patented Dec. 17, 1935 UNITED STATES PATENT OFFICE ROAD GUARD New Jersey Application November 20, 1934, Serial No. 753,979
3 Claims.
'Ihis invention relates to road guards having guard rails consisting of flat metal strips arranged in alinement with their respectively adjacent ends interfastened, one of the objects being to elastically tension these strips in a manner that is inexpensive yet safe.
In the accompanying drawing, Figures 1 and 2 show the top and traic side of a portion of a guard rail embodying the invention, while Figures 3 and 4 show similar views of one embodying a variation of the invention.
The guard rail shown by Figures 1 and 2 includes two alined flat metal strips I and 2, a flat spring metal strip 3 having a looped central portion 4 and oppositely extending alined end portions 5 and 6, and bolts 'l xing the end portions 5 and 6 of the spring metal strip 3 to the respectively adjacent end portions of the two strips I and 2.
It is obvious that tensioning of the strips is thus eiected in an inexpensive manner. When a vehicle collides with the guard rail, the strip 3 simply straightens out, so that it is as strong as the guard rail strips I and 2.
The end portions of the strips I and 2 are overlapped so as to close the open face of the looped central portion 4 of the strip 3. This prevents a break in the continuity of the guard rail.
Figures 3 and 4 show the same elements as have been described except that the end portions of the strips I and 2 are not overlapped. Instead, a fiat metal plate 8 is fixed to the end portion of one of the strips I and 2, the one numbered 2 in this instance, and extends to sliding overlapped relationship with the other of the end portions of the strips so as to close the open face of the looped central portion 4 of the strips 3.
We claim:
1. In a guard rail, the combination of two alined 5 iiat metal strips, a flat spring metal strip having a looped central portion and oppositely extending alined end portions and fastenings fixing the end portions of said spring metal strip to the respectively adjacent end portions of said two metal 10 strips.
2. In a guard rail, the combination of two alined iiat metal strips, a iiat spring metal strip having a looped central portion and oppositely extending alined end portions and fastenings xing the end portions of said spring meta-1 strip to the respectively adjacent end portions of said two metal strips, the end portions of the latter being overlapped so as to close the open face of the looped central portion of the former.
3. In a guard rail, the combination of two alined flat metal strips, a iiat spring metal strip having a looped central portion and oppositely extending alined end portions, iastenings fixing the end portionsof said spring metal strip to the respectively adjacent end portions of said two metal strips, and a iiat metal plate xed to the end portion of one of said two metal strips and extending to sliding overlapping relationship with the other of the end portions of said two metal strips so as to close the open face of the looped central portion of said spring metal strip.
