Description:
SUMMARY OF THE INVENTION
The invention is a manually maneuverable sign or signal device adapted for use by personnel such as flagmen, individuals controlling traffic at intersections or by any person controlling traffic or other movements in the vicinity of construction sites or otherwise.
Persons other than traffic officials or uniformed officers are frequently called upon to direct or control traffic at intersections or in the vicinity of construction sites or areas where streets are being worked on to control traffic to prevent accidents that might otherwise arise by reason of areas being blocked off, closed or otherwise. Typically persons who undertake to control traffic at intersections, as for example, individuals who assist children in crossing busy streets on their way to school or otherwise use an ordinary hand sign resembling a paddle with a short handle with the word "Stop" printed on it. Similarly workmen in the vicinity of construction sites or on streets where street work is being done undertake to control traffic either by way of a small hand flag or without any signalling device at all. Such forms of warning or signalling devices are primitive or are less than adequate for their purpose. This is particularly true since the individual manipulating the warning or traffic device is frequently himself subjected to danger. This is true because in effectively use such warning or signalling device, the user himself has to position himself in the path of the moving traffic or too close to it to be safe. Motorists tend in fact not to pay the same degree of attention to such an unofficial individual directing traffic as they would to a uniformed officer typically armed and wearing white gloves and thus accoutered with the symbols of authority which the unofficial individual is lacking. Furthermore, such primitive signalling or warning devices as are referred to may be heavy, and not easy to maneuver or manipulate.
The herein invention provides a warning or signalling device which overcomes all of the drawbacks and deficiencies as referred to in the foregoing as well as providing a number of other significant advantages as will be pointed out. In a preferred exemplary form of the invention as described in detail herein, it takes the form of a sign having a laterally extending handle of appropriate length for the purpose with a hand grip at the end of the handle. Adjacent to the sign is provided a supporting leg pivoted or hinged to the handle so as to adapt the device to various forms of utilization. Firstly, the object is realized that the sign can be held in the most effective position for serving its purpose of giving warning while the user holds it in a safe position at a distance from the sign itself. Furthermore, the effort required to use the sign is minimized by way of the supporting leg which supports the sign at a position adjacent to it. The user then merely has to stabilize it and furthermore can very easily automate it by oscillating it about its pivot, the effort required to do this being minimal. Further, the supporting leg is pivoted or collapsible so that it can be folded against the handle either for storage or transportation or for then using the sign with the handle in a vertical position and supported from the ground.
All of the foregoing objects are readily achieved by the article of the invention. Many further objects and additional advantages of the invention will become apparent from the following detailed description and annexed drawings wherein:
FIG. 1 is a view illustrating one manner of utilization of the invention;
FIG. 2 is a view illustrating another manner of utilization of the invention wherein the sign is supported directly by the supporting leg in a vertical position;
FIG. 3 is a view showing the sign with the supporting leg collapsed about the handle and with the handle in a vertical position;
FIG. 4 is a detailed view illustrating a pivoted joint between the handle and supporting leg;
FIG. 5 is a sectional view taken along the line 5--5 of FIG. 4.
Referring now more in detail to the various figures of the drawings which illustrate a preferred exemplary form of the invention, numeral 10 designates a rectangular sign of suitable size which may be made of any preferred material such as plastic, wood, or otherwise. In the form of the invention shown, the sign has the word "Stop" imprinted on one side and the word "Slow" imprinted on the opposite side. Numeral 12 designates a handle which in the exemplary form of the invention is a long bar of hollow square cross-section which may be metal, plastic, or otherwise. The sign 10 is secured to the handle 12 by any suitable means such as rivets, bolts, adhesion or otherwise.
At the end of the handle 12 is a hand grip 14 in the form of a bar having end parts suitably secured to the top side of the handle 12 and providing room so that it can be gripped or grasped either with one hand or two.
In the exemplary form of the invention two rectangular signs are shown, one having the word "Stop" on it being parallel to the handle 12 and the other one having the word "Slow" on it designated at 16 being transverse to the handle 12.
Numeral 22 designates a supporting leg which may be made of any suitable material and it may be made from bar stock like the handle 12 or it may be simply a strip of plastic, wood or metal. At its lower end a supporting end 22 is bifurcated having two diverging parts as designated at 24 and 26. The supporting leg has pivotal or hinged attachment to the handle 12, as shown more in detail in FIGS. 4 and 5. Referring to FIG. 5 attached to the sides of the handle 12 by welding, soldering or otherwise, are two bracket pieces 30 and 32 which form a yoke. The upper end of the supporting end 22 is pivoted between the bracket pieces 30 and 32 by means of a pivot shaft 36 which is held in place by cotter pins 38 and 40. The supporting leg 22 is rotatable about its hinge or pivot so that it can be folded or collapsed into a position as shown in FIG. 3. However, a stop member 44 is provided as may be seen particularly in FIG. 4 secured as by welding or the like to the bracket pieces 30 and 32 in a position which limits the angular or rotative movement of the supporting leg 22. The stop member 44 is positioned to limit the angular movement of the supporting leg 22 so that it will be retained in substantially a 90° position relative to the handle 12 as shown in FIG. 1.
The great versatility, adaptability and utility of the article is illustrated in FIGS. 1, 2 and 3. FIG. 2 illustrates a position wherein a user grasps the grip 14 with the handle 12 extending out into an intersection while the user is safely at the curb or on the sidewalk. The supporting leg 22 is in a substantially vertical position with the bifurcated end part formed by the diverting extensions 24 and 26 resting on the street so that the entire weight of the unit is supported. Little or no effort is required by the user since he does not have to hold the weight of the assembly but only has to stabilize it and if desired can oscillate the handle to give it dynamic moving effect to the sign and thereby enhance the warning qualities.
FIG. 1 illustrates a utilization of the invention which is a static utilization not requiring the presence of a user at all. In this utilization the handle 12 is simply allowed to have its end rest on the ground or pavement as shown so that it is tilted with the sign in the position shown but yet readily visible and readable. The sign can be left in this position at any place or area where it is necessary or desirable that a warning or signal be displayed.
FIG. 3 illustrates the sign with the supporting leg 22 folded or collapsed against the handle 12. As shown in FIG. 3, the handle 12 is in a vertical position and in this position its end may be stuck into the ground or otherwise supported so that the handle is vertical. The "Slow" sign as previously explained is positioned transversely with respect to the handle 12 so that the sign as a whole appears as in FIG. 3.
In the positions of FIGS. 1 and 2 the hinge stop 44 acts to hold the supporting leg 22 in substantially a ninety-degree position as shown.
From the foregoing those skilled in the art will readily understand the nature and utilization of the invention and the manner in which it achieves and realizes all of the objects and advantages as set forth in the foregoing as well as the many additional advantages that are apparent from the detailed description.
The foregoing disclosure is representative of a preferred form of the invention and is intended to be interpreted in an illustrative rather than a limiting sense, the invention to be accorded the full scope of the claims appended hereto.
