A miniature wind sock assembly adapted to be coiled and inserted into a small plastic display container. The wind sock is supported on a spring mast in turn fixed to a spring base bracket that is designed to be attached either to standard bicycle handlebars or to standard adjustable headband hats.

Description:
BACKGROUND OF THE INVENTION 
     Attention-attracting novelty items, some of which also have some utility, have achieved a considerable degree of commercial success over the last several decades in the United States as well as many foreign countries. Such novelty, or semi-novelty and utility items frequently take the form of pictorial T-shirts, pennants, flags, badges and banners. Many of these items such as flags and pennants have rigid masts originally constructed of wood that are not only subject to breakage, but also require a rather large shipping container for transport. Moreover, because of the mast length and the relatively low cost of the product, the flag assembly cannot be economically packaged in individual containers and retailers hesitate to purchase any product that is shipped in bulk form and not individually containerized for sale to the consuming public. 
     Another problem with masted semi-novelty products is that because most retailers will not handle such bulk packaged products, there is no readily definable channel of trade, and as a result they have had only limited sales success. Their size also precludes them from many channels of trade handling other novelty items such as coin-operated vending machines. 
     It is a primary object of the present invention to ameliorate the problems noted above in semi-novelty masted products. 
     SUMMARY OF THE PRESENT INVENTION 
     According to the present invention a miniature wind sock is provided that is adapted to be coiled and then inserted into a small plastic container for both shipment and display to the customer either at a retail outlet or in coin operated vending machines. 
     Toward these ends the present miniature wind sock includes a one-piece rigid plastic wind sock that has a downwardly opening projection that fits over the upper end of a coiled spring mast that has its lower end pressed into a fitting ia a one-piece flat spring bracket with an upwardly opening loop and a larger downwardly opening loop. 
     The bracket&#39;s upwardly opening loop receives one side of a strap in an adjustable plastic head strap, a standard strap found in many visor-type sport caps. This enables the wind sock assembly to be mounted on the rear of the owner&#39;s hat for full display to all without interfering with the user&#39;s sporting activities or vision. Such adjustable plastic head straps have a projection that fits through one of a series of apertures in an opposed strap to adjust the size of the headband. This projection, prior to being inserted into one of the apertures is simply pushed through an aperture in the bracket and then through the other strap so that the straps clamp against the bracket holding the entire wind sock assembly in a vertical position with the wind sock pointing in the direction of the user&#39;s head. 
     This bracket also has a downwardly opening loop that is sized to fit over and clamp against a standard handlebar of a bicycle which is a very accessible support for the wind sock. 
     An important aspect of the present invention is that the coil spring mast has sufficient flexibility so that the mast can be wound around the wind sock with the bracket and then inserted into a very small plastic container at the manufacturing location. This container holds the wind sock assembly in the coiled position during shipment as well as during display to potential customers either in retail outlets and commercial coin operated vending machines.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings, a wind sock assembly 10 is illustrated and is seen to include a flat spring lower bracket 11, a closely coiled spring wire mast 12, and a wind sock 14 mounted on the upper end of the mast 12. 
     The wind sock 14 is a one-piece rigid plastic injection molding and is seen to include a frusto-conical body 16 with an annular boss projection 17 extending downwardly integrally from the body portion 16. As seen in FIG. 4 the projection 17 has an internal bore 19 that receives with a slight interference fit upward end 21 of spring mast 12. The spring mast 12 may, for example, be constructed of 0.018 inch wire, have a length of 41/4 inch and an outer diameter of 5/16 inch. In this way the wind sock boss 17 may be pressed on the spring 12 without the need for special tools or any adhesive whatsoever simplyfying its manufacture. 
     The bracket 11 is constructed of flat steel stock bent to the configuration illustrated in the drawings and then hardened to provide the bracket with the next necessary spring characteristics. This flat stock is bent into an annular shape forming fitting 24 with a internal diameter 25 slightly less than the spring mast 12 so that the spring mast may be pressed into the fitting 24 also without any special adhesives. Bracket 11 also includes an upwardly opening loop 26 that has a vertical leg 27 with an aperture 28 therein seen in both FIGS. 2 and 7. 
     As seen in FIG. 7, when it is desired to mount the wind sock 10 on the rear of a hat with a standard adjustable head band, strap 30 is positioned against the forward surface of bracket leg 27 with strap post 32 inserted through aperture 28, and thereafter through one of the apertures in cooperating strap 33. In this way the straps squeeze against bracket 27 holding the entire wind sock assembly in the position illustrated in FIG. 5 with the wind sock pointed in the direction of the user&#39;s head. 
     The bracket 11 has a downwardly opening arcuate loop 35 that is sized somewhat smaller than the diameter of a standard handlebar, and this loop continues into a reverse bend portion 36 with a distal end loop 37. The reverse loop 37 acts as a camming surface to open the loop 35 as the bracket snapped over a handlebar as illustrated in FIG. 1. 
     As seen in FIGS. 8 and 9, a plastic container 40 is provided for the present wind sock and is seen to include a lower base 41 and an upper transparent semi-spherical cover 42. The base 41 has an annular integral flange 44 with a tapered lead-in-surface 45 and an annular radial extending locking groove 47. The transparent cover 42 has a lower annual rim 48 that is cammed radially inwardly by surface 45 as the cover 42 is pushed into base 41. As rim 48 passes surface 45 it snaps into groove 47 locking cover 42 to base 41. 
     An important aspect of the present invention is that the container 40 has an inside diameter only slightly greater than the length of the wind sock 14 and the wind sock is held by the container in a coiled position, thus requiring a far smaller container than would be required to package it in its relaxed state illustrated in FIGS. 1 to 4. After manufacture, the manufacturer&#39;s packaging facility coils the mast 12 around the wind sock 14 and inserts it into the cover 42. The cover holds it in the coiled condition as the base 41 is inserted over the open end of the cover 42.
