4 Claims. (Cl. 40-125) This invention relates to signs and pertains particularly to a sign of a new and improved construction, adapted to be mounted on a lamp pole or the like.
This application is a continuation of the applicants co-pending application, Serial No. 97,503, filed March 22, 1961, now abandoned.
One object of the present invention is to provide a new and improved sign which may be mounted in a secure manner on a pole, with a minimum of supporting structure.
A further object is to provide a new and improved sign of the foregoing character which may be mounted on a pole very quickly and readily by one man.
Further objects and advantages of the present invention will appear from the following description, taken with the accompanying drawings, in which:
FIG. 1 is a perspective view showing the first stage in the erection of a pole sign to be described as an illustrative embodiment of the present invention.
FIG. 2 is a perspective view showing the second stage in the erection of the sign.
FIG. 3 is a fragmentary perspective view showing a detail of the sign construction.
It will be seen that FIGS. 1 and 2 illustrate a sign adapted to be mounted on apole 12. The sign will find many applications, but is particularly advantageous for use as a temporary or short term sign at automobile servvice stations or the like. Thesign 10 is adapted to be installed on an existing pole which has previously been erected to support lamps, a permanent sign, or the like.
Thesign 10 may be mounted on poles of various types, but is especially well adapted for mounting on poles of the illustrated type which taper upwardly in cross section. It will be seen that the illustrated pole is substantially square in cross section, but the sign may be mounted on poles of any suitable cross sectional shape.
As shown, thesign 10 comprises a pair ofplacards 14 and 16 which may be made of cardboard or any other suitable sheet material. Initially, theplacard 14 is folded accordion fashion into three panels 14a, 14b and 14c. Similarly, theplacard 16 is folded into three panels 16a, 16b and 160. Thepanels 14 and 16 are folded alonghorizontal fold lines 14d, 14e, 16d and 16a.
The upper edges of theplacards 14 and 16 are secured to wood boards or other similar resilient supportingmembers 18 and 20. In the first stage of the erection of thesign 10, theboards 18 and 20 are pressed against opposite sides of thepole 12 by means of a pair ofsprings 22 or other resilient members. As shown, thesprings 22 are of the coiled extension type and are stretched betweeneye bolts 24 extending through theboards 18 and 20. Thesprings 22 are on opposite sides of thepole 12 so as to retain theboards 18 and 20 on the pole. The force of thesprings 22 clamps theboards 18 and 20 against opposite sides of thepole 12.
It is preferred, as the next step in the erection of thesign 10, to bring the ends of theboards 18 and 20 together. This may be done in various ways, but it is convenient and easy simply to stringwires 26 throughholes 28 in the ends of theboards 18 and 20. The ends of thewires 26 may then be twisted together, as shown at 30,
3,217,437 Patented Nov. 16, 1965 ice so as to draw the ends of theboards 18 and 20 together. This flexes the boards into a bow shape, as clearly shown in FIG. 2. The flexure of theboards 18 and 20 provides additional compressive force which clamps the boards against the opposite sides of thepole 12.
Next, thesign 10 is lifted up thepole 12, and theplacards 14 and 16 are allowed to unfold. The edges of theplacards 14 and 16 are preferably clipped together by means ofstrips 32. Each of thestrips 32 may be riveted or otherwise secured to theplacard 14 and may be threaded through acorresponding slot 34 in theplacard 16. Thestrips 32 may then be bent across the edges of theplacards 14 and 16 and behind theplacard 14, as clearly shown in FIG. 3.
The joining of the edges of theplacards 14 and 16 rigidities the placards to such an extent that the placards may be shoved up thepole 12 to the desired final elevation. This operation is clearly shown in FIG. 2. Finally, the lower edges of theplacards 14 and 16 may be secured to thepole 12. This may be done by stringing a wire 36 around thepole 12 and throughopenings 38 in theplacards 14 and 16 adjacent the lower edges thereof. Theopenings 38 may be reinforced with grommets or the like. The wire 36 is pulled up tight and is secured in place by twisting the ends of the wire together.
Even though thepole 12 tapers upwardly, theboards 18 and 20 remain securely clamped to the'pole by the force of thesprings 22, and the additional clamping force due to the fiexure of theboards 18 and 20. The resilient action of thesprings 22 compensates for the upward taper of thepole 12. Thus, thesign 10 is securely retained at any desired elevation on thepole 12, without any adjustment.
It will be evident that the sign It) may easily be erected in a matter of a few minutes. One man can easily erect the sign without any assistance. Normally it is not necessary to use a ladder in the erection of the sign. The sign is securely maintained on the pole and is resistant to the force of the wind.
Various modifications, alternative constructions and equivalents may be employed without departing from the true spirit and scope of the invention, as exemplified in the foregoing description and defined in the following claims:
