BARRICADE Filed Aug. 12, 1965 INVENTOR Gwen/02' COLL/N8 United States Patent 3,330,534 BARRICADE Clarence Collins, 713 Greenlawn Ave., Columbus, Ohio 43223 Filed Aug. 12, 1965, Ser. No. 479,195 4 Claims. (Cl. 256-64) This invention relates to both civil engineering and building construction, and more particularly to a barricade used wherever roads are made and/ or bridges, buildings, and the like are erected, since construction work of this nature requires some form of temporary structures in the form of barricades to be placed wherever there is danger of people falling into openings in the ground or over objects used during the construction work.

As nearly everyone who has ever done construction work of the above noted nature well knows, barricades are seldom ready-made objects but are usually made whenever needed with whatever materials may be at hand. This is not only time-consuming labor, but more often than not results in barricades of questionable value that can sometimes cause more injuries than they pre- Vent.

It is therefore the principal object of this invention to provide a barricade than can be manufactured in quantity and retailed to contractors and the like at a price anyone having need for barricades can afford.

Another object of this invention is to provide a barricade of the character herein described that can be used over and over again and will last a lifetime.

Another object of this invention is to provide a barricade that can be set-up in but a moment of time.

Another object of this invention is to provide a barricade that can be taken apart for storing, when not in use, in a minimum of space or for transporting from one job to another.

Still another object of this invention is to provide a barricade to which one or more warning flags or lights can be attached.

The foregoing and other objects and advantages of this invention are apparent from the following description taken with the accompanying drawing, in which:

FIGURE 1 is a perspective view of this invention setup and ready for use.

FIGURE 2 is an end view of this invention.

FIGURE 3 is a perspective view of that detail part of this invention known as the end plug.

FIGURE 4 is a top view of that detail part of this invention known as the collar.

FIGURE 5 is a bottom view of FIGURE 4.

Referring now more specifically to the drawing, the reference numeral indicates the invention in its entirety which comprises a horizontally disposed metal pipe 11 having a plurality of spaced openings 12 therein in which may be placed either signal flags or signal lights, both of which are indicated by the use of phantomv lines in the aforesaid FIGURE 1 of the accompanying drawing. A round metal collar 13 having an opening '14 in the top thereof and a like opening 15 in the bottom thereof is screwed or otherwise secured on each end of the aforesaid pipe 11. Two metal legs 16 made of angle iron and having angularly cut ends are placed in the

openings

14 and 15 of each collar 13 and secured at the upper end by the rivet 17 or its equivalent. An end plug 18 having a square head 19 is screwed or otherwise secured in the outer end of each one of the two collars 13. Plugs 18 not only close the ends of collars 13 but a comparison of FIGURES 3, 4 and 5 make it clear that the dimensions are such that the end of plug 18 will bear against legs 16 to force these legs against corresponding edges of

openings

14 and 15 to rigidly secure the parts of the barricade.

It is obvious from the just described construction of this invention of a barricade that there is herein provided a barricade that is not only durable, but a device that cannot be blown over by a strong wind since its legs at each end are secured by the previously mentioned rivet 17 to form an inverted V when viewed from the end. The invention can also be taken apart in but a moment ofiime and the legs folded for storage or transportation as mentioned in one of the objects of this invention, which can be made any desired size one may desire. One obvious place to store legs 16, when not in use, would be within pipe 11.

Changes and modifications may be made in this invention in so long as they fall within the scope of the appended claims.

What I now claim as Letters Patent is:

1. A barricade of the character described, comprising a horizontally disposed tube, two pairs of legs each pair pivotally secured together at their upper ends to form an inverted V, the tube having an upper opening near each end thereof, a lower opening directly below each upper opening, the top of each inverted V extending through one upper opening and the corresponding lower opening with the inverted V transverse to the tube, and the upper and lower openings proportioned so that their edges contact the inverted V.

2. The combination of claim '1 in which the tube comprises a central pipe, a collar secured to each end of the pipe in line therewith and the openings are in the collars.

3. The combination of claim angle iron.

4. The combination of claim 1 including a plug in threaded engagement with each end of the tube with the inner end of each plug contacting the corresponding inverted V whereby the plugs close the ends of the tube and rigidly secure each inverted V to the tube.

Claims

1. A BARRICADE OF THE CHARACTER DESCRIBED, COMPRISING A HORIZONTALLY DISPOSED TUBE, TWO PAIRS OF LEGS EACH PAIR PIVOTALLY SECURED TOGETHER AT THEIR UPPER ENDS TO FORM AN INVERTED V, THE TUBE HAVING AN UPPER ENDS OPENING NEAR EACH END THEREOF, A LOWER OPENING DIRECTLY BELOW EACH UPPER OPENING, THE TOP OF EACH INVERTED V EXTENDING THROUGH ONE UPPER OPENING AND THE CORRESPONDING LOWER OPENING WITH THE INVERTED V TRANSVERSE TO THE TUBE, AND THE UPPER AND LOWER PORTIONS PROPORTIONED SO THAT THEIR EDGES CONTACT THE INVERTED V.
