Safety Devices 1. Frequently, such flasher lights are mounted on barricades so that their lenses are positioned above the tops of the barricade frames.

While a flashing light of the above-indicated type is easily visible to one facing either of its lenses, it is far less visible to a person looking at if from either side. This could be a disadvantage in the case ofa dangerous traffic condition approachable from more than two directions as, for example, where it occurs at a complex intersection, since the use of a plurality of barricades positioned to cover all lanes of approaching traffic with their flasher lights would then be required for optimum warning effect.

Where a traffic barricade fitted with such a light carries a panel with indicia to attract attention to a traffic hazard, the light contributes substantially no illumination to the panel after dark, since its light rays are directed away from the vicinity of the panel toward approaching traffic.

Furthermore, the elevated position of the light prevents any significant amount of incidental illumination from reaching the panel where the latter is suspended from the cross-bar of the barricade as is normally the case. In brief summary, these barricades are heavy and awkward to handle and transport, they create hazards to persons and property when accidently struck by vehicles, and they tend to scar certain pavement surfaces. When fitted with conventional flasher lights such barricades fail to give radial visual warning of traffic hazards after dark, they are vulnerable to thievery and acts of vandalism and they fail to provide adequate illumination of attached panels to permit easy reading of nonreflective indicia thereon at night.

In its preferred form, the barricade has a built-in flasher light so designed and positioned as to eliminate all of the above-mentioned short-comings of lights conventionally employed on present day barricades.

My novel barricade is preferably a lightweight structure of tubular plastic construction comprising a substantially flat, upright segment and a pair of elongate feet. The flat, upright segment of the barricade structure is formed from plastic tubing and fittings in the shape of a rectangular frame defining a space within which one or more panels can be displayed and a pair of short legs positioned to extend downwardly from the bottom corners of the rectangular frame.

These legs have externallythreaded lower ends, and the elongate feet have sockets intermediate their ends which are threadedly engagable with said legs.

This arrangement permits rotatable adjustment of the feet between positions perpendicular to the plane of the flat, upright segment of the barricade structure, to provide standing support for the barricade, and positions substantially coplaner with said upright segment, to flatten the barricade for easymovement and storage. Typically, this space will be used for the display of two panels, an upper one carrying warning indicia such as, for example, diagonal stripes which reflect light for good visibility at night and a lower one carrying the identity of the contractor, municipality, or other person or organization responsible for the positioning of the barricade.

The rectangular frame portion of the barricade structure has a top member from which the upper of these two panels can be suspended with thin strips of flexible aluminum, or the like, so that it can swing under the influence of wind without exerting undue tilting force on the barricade in stormy weather. The bottom panel can be fastened between the lower parts of side members of the rectangular frame portion of the barricade structure by means of thin flexible strips of material similar to those used for support of the upper panel.

In view of the foregoing, it will be apparent that my novel barricade is of lightweight plastic construction and adapted to stand on a pair of elongate feet which distribute its weight on a road surface in such manner as to prevent scarring of the surface, unlike the conventional sawhorse traffic barricade whose angle iron feet sink into and scar certain pavement surfaces.

It will also be apparent thatmy novel barricade has feet which are easily rotatable from their normal'positions of use 'to.

By virtue of its lightweight tubu- Iar plastic construction, the barricade poses little danger when struck by a'vehicle. Thus, the tubular framework of the barricade will give before it can do any I damage to the striking vehicle, and if the barricade, or. In its preferred form, the novel barricade of this invention has a flasher light built into one of the side members of the rectangular frame portion of its flat uprightsegment.

The flasher light has a tubular lens which directs the light rays laterally outwardly to give radial warning of the presence of the barricade. This tubular lens is preferrably positioned in the top portion of one side of the flat upright segment of the barricade, and forms the upper part of the structure making up that side of the barricade framework. The light is batterypowered, and the battery fits downwardly into the hol-. It will thus be seen that the a flattened shape for convenience of handling and storage; 1.

It is another object of the invention to provide such a barricade which is relatively stable in cross winds and designed to rest lightly on pavement surfaces without scarring effect thereon. It is yet another object of the invention to provide such a barricade which poses substantially no threat of harm to an impacting vehicle and minimum risk of harm to persons or property in the vicinity of'the impact.

Still another object of the invention is to provide such a barricade with flasher light means clearly visible from all sides to give warning of unsafe traffic conditions to truck'andautomobile drivers approaching the barricade from any direction. Yet another object of the invention is to provide such a barricade with a flasher light of difflcultly removable character to maximize the odds against theft or vandalism of the light.

Another object of the invention is to provide such a barricade with flasher light means capable of illuminating a warning panel carried thereby. Other objects, features and advantages of the invention will become apparent in the light of subsequent disclosures herein. FIG 9 is a perspective viewof an adaptor and drip shield fitting fixedly secured to the upper end of the flasher light lens to form a part of thelight unit.

Barricade B has a built-in flasher light L, soon to be described. The barricade is constructed, for the most part, from plastic tubing-and fittings, and is essentially an upright, generally coplanar structure 10supported on a pair of elongatefeet 24 and 25 of similar size and shape.

The upright structure 10 has parallel left and right sides 12 and 14 as seen in FIG. The bottom-cross segment 18 is spaced upwardly from the bottom ends of the left and right sides 12 and 14 of the upright structure, and defines, with the top cross segment 16 and those parts of the left and right sides 12 and 14 of the upright structure thereabove above segment 18 , sometimes hereinafter referred to as jambs, a rectangular frame in which a pair of panels 26 and 32 are displayed, as will be discussed in greater detail below.

Starting at the top, and proceeding clockwise around the aforesaid rectangular frame as seen in FIG. The tubing and fittings of upright structure 10 are preferably of polyvinyl chloride PVC plastic construction, although they could be made of any other suitable plastic material if desired.

These parts can even, in fact, be of other than plastic construction, within the scope of my invention, although the latter is preferred because of the ready availability, lightness of weight and high strength of PVC, or equivalent, plastic parts. The top tubing section 17, right side section 38 and bottom sec tion 41 as seen in FIG.

The tubing and fittings are friction-fitted together to form upright structure 10, and the resulting joints are preferably glued with a suitable cement, or the like, to add strength and rigidity to the barricade framework, except that the joint between elbow 42 and tubing section 38 is not glued, but bolted, for a reason hereinafter explained.

Since, as indicated above and shown in FIG. Friction-fitted into the lower ends of tees 40 and 58, and preferably glued in position there, are two short sections of plastic, preferably PVC, tubing, and Tubing sections 20 and 22 are-threaded upwardly from their lower ends, and form, in combination with downturned outlets of tees 40 and 58 see FIG.
