Ryan, lurlingame, Calif. Application .lune 27, 1955, Serial No. 518,073 4 Claims. (Cl. 40-139) This invention relates to a new and improved animated display sign. More particularly the invention relates to a sign which may be supported elevated high in the air and which is so constructed and mounted that it receives a high degree of animation which attracts attention. A distinguishing feature is the absence of twirling, an undesirable feature of many signs of this general type, inasmuch as rapid twirling makes it diflicult to read the message on the sign.

@ne of the features and advantages of the invention is the fact that its animation results from a combination of three different movements. ln the iirst place, the sign is mounted on a supporting rod by means of a connection which permits rotation of the sign relative to the rod, but at the same time the rod is off centerl with respect to the sign so that a weathervane, as distinguished from a twirling motion, results from wind action on the sign. A second movement imparted to the sign resuits from the fact that it is'mounted on a relatively long, ilexible tube or rod which bends or tlexes. A third movement results from the fact that the lower end of the tube or rod which support-s the sign is received inside a larger diameter pipe Xed to the ground or other stationary support, the lit between the upper tube and lower tube being loose to permit tilting or rocking of the upper tube.

Another feature of the invention is the fact that it may be installed by unskilled labor without the use o special tools and equipment, and, further, the fact that it is not necessary for the installer to mount a ladder, despite the fact that the sign is displayed many feet above the ground. y

An important advantage of the invention is the facility with which the advertising message of the sign may be replaced as occasion requires with a minimum of time and labor and without the necessity of scaling high ladders.

An additional feature of the invention is the facility with which it may be employed in conjunction with threedimensional display devices.

A further feature of the invention is the fact that when installed in locations where there is no wind, a motor may be connected to the sign to impart animation.

Still another feature of the invention is the fact that the supporting structure of the sign may be anchored in the ground or attached to poles, walls, the outer edges of .existing signs, store counters, or the like, in order to attract attention.

Other objects of the present invention will become apparent upon reading the following specication and re-v ferring to the accompanying drawings in which similar characters of reference represent corresponding parts in each of the several views.

The present invention provides a mounting for a sign 20 bearing an advertising message and particularly relates to the mounting structure for such a sign. The mounting structure consists of several elongated tube or rod sections which are telescopically tted together so that the sign 20 is elevated a considerable height above its support. The lower end of the mounting structure comprises a pipe 2l which is provided with a cap 22 at its lower end, the lower end of the pipe 2 and cap 22 being buried inthe ground 23, so as to atord stability to the sign. Pipe 21 may be, for example, 6 to 8 feet in length, so that its upper end is accessible to the installer of the sign without using a high ladder. A tube 24, having an external diameter considerably .less than the internal diameter of the pipe 2l, is mounted in the upper end of the pipe and is provided with a collar 26 secured to tube 24 by means of set screws (not shown), or other conventional means, so that the lower end of the tube 24 is positioned suiciently inside the upper end of the pipe 2li to prevent dislodgment. As shown in Fig. l, the loose t permits a whipping movement of the sign as the lower end of tube 24 rocks baci; and forth in pipe 21. Tube 2d may be assembled in several sections jointed together in any convenient manner.

At the upper end of the tube 24 there is a smaller diameter rod Z7 which is of a flexible nature. The rod 27 is provided with a second collar 25 secured thereto by means of set screws (not shown), so that the lower end of rod 27 is maintained in position in the top of tube 24. The upper end of rod 27 ts inside a bearing tube 23 in the sign 2li. Each end of the bearing tube 2S is provided with a collar 29 having a neel: 3l fitting inside the tube 25 and an external shoulder 32. A collar 33 is tapped to receive a set screw 33a which bears against the rod 27 and secures the bearing tube 2S and rod 27 in such position as to permit rotation of the one relative to the other, but to prevent axial movement. The upper end of 'bearing tube 28 is capped with a cap 30 threaded on the end of rod 27 to protect the bearing assembly against atmospheric conditions.

Sign 2i) consists of two cardboard sheets 36 or a single piece of cardboard bent into substantially parallel sheets 36. Positioned transversely to the axis of the bearing tube 28 are two upper and two lower strips 37 of relatively inflexible material, such as sheet metal. The cardboard 36 is secured to the strips 31"/v by means of staples 38 which pass through the sheets 36 in close proximity t-o the longitudinal edges of the strips 37. Bearing tube 28 is provided with four flattened external surfaces 39, two diametrically opposed at the top to receive top strips 37 and two diametrically opposed at the bottom to receive bottom strips 37 so as to prevent rotation of the sign 20 relative to the bearing tube 23. lt should be pointed out that the bearing tube 2S is eccentric to the center line of the sign 20 which results in a weather vane rather than a whirling movement of the sign.

The animation of the sign 20 shown in Fig. l is the result of the action of the wind blowing thereon. There are three simultaneous motions imparted to the sign. The first is a weather vane action, as the direction of the wind or wind Velocity changes, which results in a rotation of bearing tube 28 relative to the rod 27. The second movement is a exing of the rod 27 and tube 24 by reason of their resilient and exible nature. The third movement results from the fact that the t between the lower end of the tube 24 and the pipe 21 is sutiiciently loose to permit a tilting of the tube 24 which causes a rocking movement of the sign.

Turning now to the modification shown in Fig. 5, it is seen that the sign which is the subject of this invention may be adapted to installation on existing structures. An existing sign 41 mounted from a standard 42 by means of spring hinges 43 is illustrated in Fig. 5.. Attached to the sign 41 are a pair of horizontally projecting brackets 44 which engage bottom tube 46, which corresponds in function and position to the pipe 21 shown in Fig. 1, but is of lesser length. in other respects, the sign illustrated in Fig. is substantially identical with thaty shown in Fig. 1.

In Fig. 6 is shown a modificationsuitable for a location where there is no wind, such as the interior of a store, or the like. The sign mounting may be attached to a store counter 51 or similar stationary location. The bottom tube S2 is suitably anchored thereto Land they upper end of the tube 52 is supplied with a motor 53 fastened thereto by means of strap 54. The upper end of the motor shaft 57 is provided with an eccentric 56 which bears against tube 24. Thus as the motor revolves, the

eccentric causes flexure of the tube 24, producing a whip- 7 ping action generally similar to that pointed out in connection with Fig. 1.

Figs. S and 9 illustrate still a further modified form of the invention. in particular, these drawings illustrate a modified form of rotatable bearing assembly by which the display signs may be rotatably supported. Fig. 9 illustrates the details and construction of a rod bearing assembly and Fig. S illustrates how a plurality of the assemblies may be effectively utilized to support a plurality of display signs of different dimensions and shapes, and at different heights relative to one another.

Referring now more specifically to Fig. 9, the supporting rod and tubular bearing assembly therein illustrated generally at 641 comprises a flexible, vertical sign supporting rod 61 which may be considered generally equivalent in structure and function to iiexible rod 27 in Figs. 1 and 6, for example. The lower end of rod 61 is rotatably supported within a crimped bearing sleeve or tube 62 and the upper end of rod 61, in turn, rotatably supports a similarly crimped bearing tube 62a. More specifically, bearing tube 62 comprises a length of tubular material formed with an annular crimp 63 defining an interiorly projecting circular bearing seat or ledge 64 of smaller diameter than the rod 61 which it rotatably supports. The upper bearing tube 6.2a may be of identical construction to lower crimped tube 62 and is also formed with an annular crimp 63 defining an interior bearing ledge or seat 64a.

Referring now particularly to Fig. 8, the display sign structure therein disclosed comprises a primary display sign indicated at 66 rotatably supported on a vertical rod 67 for weather vane movement. For purposes of convenient explanation, sign 66 and its supporting standard 67 may be considered as equivalent to sign 20and vertical support 27 heretofore shown and described with reference to Figs. 1 and 6. Supported above and by primary sign 66 are a plurality of secondary display sign units such as indicated at 68, 69, '76, 71, 72 and '73, and each of which is supported for iiexible and rotatable weather vane movement by one of the fiexible rod and bearing tube assemblies 66 shown in detail in Fig. 9. Thus, for example, sign 68 is supported on an associated flexible rod 61, the lower end of which is telescoped within a crimped bearing tube 62. The upper end of rod 61 carries a corresponding crimped bearing tube 62e to which the sign pieces 68 are stapled or otherwise attached in the manner previously described. Secondary sign 69 is similarly supported to primary sign 66. It is observed that the upper andV lower crimped bearing tubes 62 and 62a associatedl with the fiexiblerod 61. in each instance provides twov bearing 4 surfaces. 64v andv 64a, respectively, about which each sign 68 and 69 can rotate in weather vane fashion.

It is further observed that each of the secondary signs 68 and 69 support above them two additional signs 70-71 and 7273, respectively. Each of these latter mentioned signs is exibly and rotatably supported by identical fiexible rod and bearing assemblies 60, each comprising a rod 61 and upper and lower crimped bearing tubes 62 and 62a. Signs 70 and 73 are shown as being made of flat sheet material stapl'ed or otherwise secured to a respectively associated bearing tube Signs 71 and 72, on the other hand, are shown as supporting a three-dimensional. display representation of a product such as a tubular body 76 configured and decorated, as by lithographing, to represent a canned food product.

The closed ends of each of the tubular sign displays 76 may be apertured with registering holes 78 to receive a bearing tube 63a. 62a may be flanged outwardly as indicated at 79 to provide an abutment shoulder or ledge on which the bottom end of the tubular sign may rest.

Although the foregoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be practiced within the spirit of the invention and scope of the appended claims.
