ROAD BARRICADE Filed Dec. 28, 1962 INVENTOR. 1203521 SWQLK ATTOENEY$ United States Patent 3,168,288 ROAD BARRKZADE Robert S. Wollr, Leonard J. Kalish, Suite 1629, Du Pont Bldg, Miami 32, Fla. Filed Dec. 28, 1962, Ser. No. 247,934 9 flaims. (Cl. 25664) This invention relates to a novel road barricade.

The primary object of the invention is the provision of a simpler, more eiiicient, and more easily and quickly set .up device of the kind indicated, which eliminates the need for the loosening and tightening of bolts or other tastenings when setting up the device.

Another object of the invention is the provision of an inexpensive and long lasting device of the character indicated above, which comprises at least one and usually a pair of standards and any desired barricade bar, the standards consisting of single, generally vertical rods or bars having low-profile ground-engaging feet, on their lower ends, which, because of their low profiles are not subject to being damaged by the bumper bars of vehicles, and which can be run over by the tires of vehicle wheels, without necessary damage thereto. Present barircades use A frame standards whose upwardly converging straight legs present obstacles likely to be struck and damaged by vehicle bumper bars and the like, when vehicles come close to the barricades, as when the barricades are set up parallel to a road, as one side of the road is being repaired and its other side is open to tratlic.

A further object of the invention is the provision of a device of the character indicated above wherein the bars or rods of the standards have vertically spaced, pivoted clips, of simple and inexpensive design, which are spaced from each other at a distance greater than the width of a barricade bar, the barricade bar being adapted to be placed freely between the clips with the standards in erect perpendicular positions, and the standards then tilted inwardly toward each other, whereby the distances between the clips are reduced and the clips are forced into secure retaining or clamping engagements with the upper and lower edges of the barricade bar, and at the same time the over-all height of the barricade is reduced to the desired height from the erect heights of the standards.

A still further object of the invention is the provision of an economical and easily serviced device of the character described above, wherein the rods or bars of the standards are provided with at least three vertically spaced bolt holes, so that the clips can be spaced at different distances from each other, by inserting their bolts through the appropriate holes, for the accommodation of barricade bars of difierent Widths, and wherein, in case of damage to clips, bolts, or standard test, these can be readily individually replaced from stock, instead of having to go to the expense of replacing the entire standards, as is now the practice; and wherein the clips are adapted to be reversed for accommodating barricade bars of different thicknesses; and wherein, in case of damaged standards, their undamaged components may be saved to make up other complete standards economically, so as to eliminate the expense of providing new standards.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

FIGURE 1 is a perspective view of a barricade in accordance with the present invention;

FIGURE 2 is an enlarged fragmentary front elevation of a portion of the barricade of FIGURE 1;

FIGURE 3 is a vertical transverse section taken on the line 33 of FIGURE 2;

"Ice

FIGURE 4 is a fragmentary schematic and diagrammatic front elevation, showing the reduction in the spacing of the clips, as a standard is tilted out of erect position, which produces clamping of the clips on the upper and lower edges of the barricade bar;

FIGURE 5 is an enlarged exploded perspective view of a clip and its bolt;

FIGURE 6 is a view like FIGURE 3, showing the clips reversed tor accommodating a barricade bar which is narrower and thicker than the barricade bar of FIG- URE 3.

Referring in detail to the drawings, wherein like numerals designate 'like 'parts throughout the several views, the illustrated barricade comprises a pair of similar standards 10, and a horizontal barricade bar or slab 12 supported thereon.

Each of the standards 10 comprises a straight, generally vertically elongated rod or bar 14, herein shown as being tubular and made of metal, such as galvanized steel. However, rods or bars of any other forms and material are contemplated by the present invention. The rods 14 have upper ends 16 and are formed at their lower ends with fiat arcuate saddles 18, which embrace one side of the middle of the horizontal cross members 26 of low profile inverted U-shaped ground-engaging feet 22, and are removably secured in place by means of bolts 24 extending through the saddles and the cross members 20, so that a foot 22 can be readily replaced.

The standard rods 14 are provided, adjacent to their upper ends, with vertically spaced upper, intermediate, and

lower bolt holes

26, 28 and 30, respectively. Additional bolt holes may be provided, it desired. In the arrangement shown in FIGURES l to 3, wherein the barricade bar 12 is relatively wide and relatively thin, upper and

lower pivot bolts

32 and 34 are inserted through the upper hole 26 and the lower hole 3t), for pivotally supporting similar but reversed upper and lower clips, or

hook elements

36 and 38, respectively.

Each of the clips comprises a relatively narrow web 40, adapted to have free bearing against one side of the standard rod 14, and having a centered hole 42 t hrough which the shank 44 of the related pivot bolt is passed, the shank having a fixed head 46 engaged with the outer side of the web 40, in opposition to a self-locking nut 48, on the other end of the shank 44, which bears freely against the other side of the standard rod.

Parallel, spaced,

horizontal arms

50, 54, extend laterally outwardly from the upper and lower ends of the web 40 and are spaced at such a distance that these arms engage opposed upper and lower, edge faces of the bolt head 46, as shown in FIGURE 2, whereby the bolt is prevented from rotating as the nut 48 is applied to the bolt shank, thereby eliminating the need to use two wrenches, when installing the clips or reversing the same.

The arms consist of flat, relatively long arms 50, having lateral transverse flanges 52, on their outer ends, which extend away from flat, relatively short arms 54, which have lateral transverse flanges 56, on their free ends, which extend away from the upper arms 50. As shown in FIG- URE 3, the short arms 54 are the inner arms and are used for supporting a relatively wide and thin barricade bar 12, whereas, as shown in FIGURE 6, the clips are reversed, by rotating them on the bolts, in addition to placing the lower bolt in the intermediate bolt hole 28, and the long arms 50 used for supporting a relatively narrow and thick barricade bar 12 The standards 10 are longer than or taller than the contemplated height of the completed and set-up barricade, and the clips are spaced from each other, at distances greater than the width of the associated barricade bar, so that, as shown, at the right-hand side of FIGURE 4, the barricade bar can be readily passed between the upper and 7 3

lower clips

36 and 38, with the standard 10 in erect position; and so that when the standard is tilted inwardly, toward the other standard, as shown, at the left-hand side of FIGURE 4, the effective distance between the upper and lower clips is reduced, while the clips pivot on their bolts, and make clamping contacts with the upper and lower edges of the barricade bar, the height of the bar bolts. Replacement of a foot 22 is simply a matter of loosening the bolt 24.

In addition to serving as a barricade, the assembly of FIGURE 1 may be grouped in multiples of at least two and in that way provide a frame for supporting planks, staging or the like.

It is to be noted that it is often the practice with pre ent barricades, where such as'a repair spot on aroadway or the like is to be guarded against traffic, to use a barricade which involves only the barricade bar and a single standard,.with one end of the bar resting upon the surface and the other end thereof supported onthe single standard. The components of the above described barricade are adapted to be used in the same way, for the same purpose.

Although there has been shown and described a preferred form of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as defined by the claims appended hereto.
