4 Claims.

This invention relates to traiiic guards, and more particularly those which are installed along highways, although not limited thereto.

One object of the present invention is the provision of a novel trafc guard which will very eiiectively resist heavy impact forces, but one which will at the same time be very cheap and easy to manufacture and install.

Another object is to provide a device of the class described which will be resiliently deformable laterally, longitudinally and vertically with respect to its supporting structure, and preclude the possibility of shearing its connecting devices, such as nuts, bolts and the like. Y

A still further object of the invention is to provide a novel traiiic guard which will be more easily discernible than the devices' oi the prior art.

rlhese and further objects will be apparent after referring to the drawings, in which:

Figure l is a side elevati-on of the device of the invention.

Figure 2 is a sectional end elevation.

Figure 3 is a sectional plan.

Figures 4 through '7 are sectional plans of various modiiied forms of the invention.

Referring more particularly to the drawings, the numeral 2 designates a plurality of a conventional type of post which is particularly adaptable tor supporting the devices of the invention, although it is to be understood that they may, in practice, be any of a number of well known designs. The fence posts 2 are provided with apertures 3 at spaced intervals.

A plurality of novel resiliently deformable elements are provided for connecting the guard of the invention to the posts 2 and each comprises broadly a substantially oval-shaped sleeve ft having enlarged and rearwardly curved portions 5 at either of its ends. The substantially oval-shaped sleeves i may be made of any suitable metal, and are preferably not continuous, having their ends overlapped on one of their sides, as shown at 6. The sides of the oval-shaped sleeves 4 which are .opposite the overlapped ends B are apertured, as at l, to permit a bolt t to extend therethrough, and through the apertures 3 in the posts 2. A lool: washer il and nut lil are provided on the inner side of each' of the posts 2 for securing the` sleeves Li in rigid position. The overlapping ends G on the sides of the substantially oval-shaped sleeves t are apertured, as at i2.

The novel guard of the invention comprises a flexible metallic strip iii of substantial width, which is suitably apertured at intervals conforming to the linear spacing of the posts 2, as shown (El. 256-13.l)

at l5. A washer it is provided for the outer side of the strip l@ and comprises a beveled strip having a plurality of spaced and countersunk apertures. Abolt ll is extended inwardly through each of the countersunk apertures in the washer i6 through each of the apertures l5, in the strip it, and through the apertures l2 in the overlapped ends t of the substantially oval-shaped sleeves il, and each receives a lock washer I9 and nut 2t on its threaded end.

Referring to Figure 4 of the drawings, the substantially oval-shaped sleeve lt is provided, as in the preferred embodiment, with rearwardly curved, enlarged portions 5, but its ends 6 are overlapped on the opposite side thereof from that shown therein.

A still further modiiication of the substantially oval-shaped sleeve Il contemplates the provision of curved and reduced extensions 5a which extend rearwardly in lieu of the enlarged curved portions 5, as shown in Figure 5.

In Figure 6 the substantially oval-shaped sleeve 0l, of Figure 4, is shown as provided with a reenforcing spring 22 having an aperture 23 which is adapted to aline with the apertures I2 in the overlapped ends 6. The spring 22 carries torwardly curving extensions 24, with oppositely curved portions Z5 on its ends for contacting that portion of the sleeve l which is adjacent the metallic strip lll.

in Figure 7 of the drawings, a still further modification contemplates a metallic sleeve composed partially of a curved plate 2l, having oppositely curved portions 28 on its ends, and being apertured along its mid-portion as at 29. A curved plate 3) is arranged with its axis extending oppositely with respect to the axis of the curved plate 2l, and is secured to the ends of the oppositely curved portions 28 of the latter by way of/being bent thereover, as at 3l.

In installing the -device of the invention, and using any o1" the substantially oval-shaped flexible sleeves heretofore described, the upper portions ofthe posts 2 are apertured, as at 33, for receiving the ends of a U-bolt 3Q which is adapted to be secured thereto by means of the usual nuts 35. A guard cable Sii is strung between the U-bolt te in a taut manner before the nuts 35 are tightened, which permits the distribution of impact forces between a number of the posts 2 independently of the metallic strip I4.

Due to the ability of the resiliently deformable sleeves to receive impact forces laterally, longitudinally and vertically with respect to the posts 2, the possibility of the shearing of the various bolts 8 and Il is eliminated, and the substantial width of the strip l 4 makes it much more readily discernible to those using the highway than any of the devices of which I am aware.

While I have shown and described several specific embodiments of my invention, it will be understood that I do not wish to be limited exactly thereto, since various modications may be made without departing from the scope of my invention, as defined in the following claims.

I claim:

1. A'highway traffic guard comprising a plurality of spaced posts arranged along the edge of the highway, a vertically disposed resiliently compressible metallic sleeve supported by at least one of said posts, a flexible metallic strip of substantial width extending horizontally across the outer surface of said sleeve in spaced relation to said supporting post, a strip extending vertically across the outer surfaces of said flexible metallic strip, and connecting means extending through both of said strips.

2. A highway traflic guard comprising a plurality of spaced posts arranged along the edge of the highway, a vertically disposed resiliently compressible metallic sleeve supported by at least one of said posts, a flexible metallic stripof substantial width extending horizontally across the outer surface of said sleeve in spaced relation tosaid supporting post, a beveled strip extending Vertically across the outer surface of said exible metallic strip, and connecting means extending through both of said strips.

3. A highway trac guard comprising a plurality of spaced posts arranged along the edge of the highway, a vertically disposed resiliently compressible metallic sleeve supported by at least one 0f said posts, a flexible metallic strip of substantial width extending horizontally across the outer surface of said sleeve in spaced relation to said supporting post, a strip extending vertically across the outer surface of said flexible metallic strip, connecting means extending through both of said strips and means within said sleeve for resisting the compression thereof.

4. A highway traic guard comprising a plurality of spaced posts arranged along the edge of the highway, a vertically disposed resiliently compressible metallic sleeve supported by at least` one of said posts, a iiexible metallic strip of substantial width extending horizontally across the outer surface of said sleeve in. spaced relation to said supporting post, a strip extending vertically across the outer surface of said flexible metallic strip, connecting means extending through both of said strips and means within said sleeve for f resisting the compression thereof, said means being connected to said supporting post.
