Filed May 20, 1959, Ser. No. 814,545 4 Claims. (Cl. 94-15) The present invention generally relates to a sign construction and more particularly to a retractable and folding sign such as the type used as warning signs on the side of a highway, in the middle of the street or intersection or the like in which the sign may be folded and then retracted completely within the ground surface so as to be completely concealed or moved to an extended position for use as an effective sign.

In present day practice, movable signs are usually placed in the center of a street to Warn approaching drivers of a school zone or of other conditions or possible dangers. Such signs are of a portable nature in that they are placed in the street for only a certain period of time or periods of time each day such as when school is beginning in the morning, during recess time and after adjournment of classes. It is usually necessary for a person or persons who place the signs in position and then remove the signs after the time of use thereof has passed. Therefore, it is the primary object of the present invention to provide a retractable sign which will be normally disposed in a concealed relation completely retracted within the ground or street surface with the device being capable of movement to an extended position in which the sign is extended vertically above the ground or street surface and then unfolded and anchored in the upwardly extended position thereby forming an effective sign having the desired qualities of signifying to approaching drivers of the conditions existing.

Another object of the present invention is to provide a sign which is foldable and retractable having novel structural arrangements for maintaining the sign in extended position in a positive manner but yet permitting easy retraction thereof.

Yet another object of the present invention is to provide a sign construction in which the upper end of the. vertically movable post is provided with a closure memher for the upper end of the casing slidably receiving the sign.

A further important object of the present invention is to provide a sign construction which is simple, easy to use, foldable, retractable, safe in operation, long lasting and generally inexpensive to manufacture.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a plan View of the sign construction of the present invention;

FIGURE 2 is a side elevation of the sign construction taken substantially upon a plane passing along reference line 2-2 of FIGURE 1;

FIGURE 3 is a vertical sectional view similar to FIG- URE 2 but showing the sign in retracted condition;

FIGURE 4 is a transverse vertical sectional view taken substantially upon a plane passing along section line 4-4 of FIGUREI;

FIGURE 5 is a transverse, plan sectional view taken substantially upon a plane passing along section line 55 of FIGURE 2 illustrating the manner of supporting the vertically movable post in extended position; and

FIGURE 6 is a transverse, plan sectional view taken 2 substantially upon a plane passing along section line 66 of FIGURE 3 illustrating the construction of the folding sign when in folded condition.

Referring now specifically to the drawings, the numeral 10 generally designates the sign construction of the present invention which is mounted within a casing generally designated by the numeral 12 disposed vertically in the street surface 14 and the underlying ground area 16 in which the sign construction 10 is completely received within the casing or housing 12 so that the upper surface of the street 14 will be smooth enabling trailic to move over the street surface without any adverse effect upon the trafiic or without any adverse effect upon the sign.

The sign construction 10 includes a vertically elongated post 18 of generally channel shaped configuration and provided with outwardly extending flanges 20 which are slidably received within a channel shaped guide 22 having inturned flanges 24 slidably receiving the outturned flanges 20 of the channel shaped post 18 thereby vertically slidably mounting the channel shaped post 18.

The upper end of the channel shaped post 18 is provided with an enlarged closure plate 26 of relatively thick construction which has reinforcing ribs 28 thereon. The plate 26 is provided with a depending projection 30 slidably received within the upper end of the post 18 and anchored thereto by a pin 32 which extends through the post 18 and the depending projection 30 on the closure plate 36. The upper surface of the closure plate 26 is provided with a suitable depression having a niche 34 which receives the bight portion 36 of a U-shaped handle which has the terminal ends thereof turned inwardly as indicated by the numeral 37. Thus, the inturned end portions 37 limit upward movement of the U-shaped handle 36 so that when the handle is elevated, the closure plate 26' and the post 18 will be elevated but when no force is exerted on the handle 36, it will be normally recessed so that it will be flush or slightly below the upper surface of the closure plate 26.

'F-ixed to the front surface or bight portion of the post 18 is an elongated central panel 38 which may be secured thereto in any suitable manner such as by welding or the like as indicated by the numeral 40.

Intermediate side or inner panels 42 are attached to each side of the central panel 38 by vertical hinge means such as a piano hinge 44. Outer or outermost side panels 46 are hingedly attached to the intermediate side panels 42 by a piano type hinge 48. The surface of the panels 38, 42 and 46 is colored a distinctive color and is provided with indicia 50 indicating the conditions existing and in this instance, the indicia spells School Zone requiring that the drivers use due caution while proceeding through the school zone.

The lower end of the post 18 is provided with an elongated support bar 52 pivotally attached midway between its ends to the post 18 by a hinge pin 54, a stop pin 56 being providedrfor limiting the pivotal movement of the support bar 52 in one direction. The support bar 52 is longer than the transverse distance across the post 18 and when the sign construction 10 is elevated above the upper end of the casing 12, the support bar 52 may be pivoted to a horizontal or substantially horizontal position thereby providing adequate support for the sign construction when it is in extended position.

The casing or housing 12 includes an elongated hollow member 58 having an annular casting or adapter 60 at the upper end thereof which is a recess 62 for receiving the closure plate 26 with the recess 62 having an annular upstanding projection 64 upon which the pivotal transverse support bar 52 rests when extending transversely and supporting the sign construction 10 as shown in FIG- URE 2. When the sign is retracted, the closure plate 26 3 a a is received within the recess 62 and rests on the projections 64 as, illustrated in FIGURE 3.

Disposed within the tubular housing or hollow member 53 is a guide supporting member 66 which is anchored by laterally extending flanges 68 secured by fastener memhers 7% with the flanges 68 being received in recesses 72 with the member 66 having a continuous rear plate 74 on which the channel shaped guide 22 is mounted throughout its length. Otherwise, the sides of the member 66 are interrupted by an elongated open area 76 Which forms a guide and housing for the sign panels when folded and retracted and also guides the movement of the post 18 in relation to the tubular member 58.

In operation, the present invention will normally be retracted with the sign construction disposed completely within the tubular housing 58 with the upper end of the plate 26 forming a closure for the annular ring member 60 and the entire casing or housing 12. When it is desired to lift and extend the sign, it is only necessary to grasp the handle 36 and raise upwardly thus raising the closure plate 26 as well as the sign construction 10 which is rigidly attached to the closure plate 26. When the closure plate 26 has been elevated to substantially its maximum position, the bar 52 will be above the upper end of the casing thus enabling the bar to be pivoted to a transverse position in relation to the casing thereby permitting the bar 52 to be rested against the aforementioned surface 64 '(FIG. 2) thus retaining the sign in extended position. The panels 38, 42 and 46 are then unfolded into a condition in coplanar relation to each other thereby providing the warning indicia on substantially a smooth and uninterrupted surface.

The indicia appearing on the sign may vary and the shape of the sign may vary to be in accordance with various standards set up by the regulatory agencies setting up standards for signs.

In actual practice it may be desirable, though optional, to stabilize or otherwise stiffen the component parts of the sign when it is in the up position illustrated in FIG. 2. To this end a stabilizing bar or brace 77 of suitable elongated form and construction will be provided, the same when the horizontal position being suitably fastened at its opposite ends as at 78 and 79 to the sign panels. When not in use the bar may be swung up to an out-of-the-way position as shown in the collapsed arrangement in FIG. 3 wherein it may be held in this position by another suitably constructed and arranged fastener 8.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, allsuitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
