Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to helmet locks and more particularly pertains to a new telescoping motorcycle helmet lock for preventing the theft of a motorcycle helmet from a parked motorcycle. 
     2. Description of the Prior Art 
     The use of helmet locks is known in the prior art. More specifically, helmet locks heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     Known prior art helmet locks include U.S. Pat. No. 4,438,877; U.S. Pat. No. 4,063,637; U.S. Pat. No. 4,274,271; U.S. Pat. No. 4,733,805; U.S. Pat. No. 3,399,855; and U.S. Pat. No. 2,032,591. 
     In these respects, the telescoping motorcycle helmet lock according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of preventing the theft of a motorcycle helmet from a parked motorcycle. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of helmet locks now present in the prior art, the present invention provides a new telescoping motorcycle helmet lock construction wherein the same can be utilized for preventing the theft of a motorcycle helmet from a parked motorcycle. 
     The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new telescoping motorcycle helmet lock apparatus and method which has many of the advantages of the helmet locks mentioned heretofore and many novel features that result in a new telescoping motorcycle helmet lock which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art helmet locks, either alone or in any combination thereof. 
     To attain this, the present invention generally comprises a plurality of rigid semi-circular portions each defined by a 30 degree section of a full sphere. As shown in FIG. 3, each semi-circular portion has an upper edge and a lower edge each with a lip formed thereon. A pair of planar, circular end plates are formed on diametrically opposed points on each semi-circular portion. Such end plates are each rotatably mounted with respect to the end plates of the remaining semi-circular sections. For reasons that will soon become apparent, a hole is formed in at least one end plate of each semi-circular portion at a position different from that of the remaining semi-circular portions. In use, the semi-circular portions have an extended orientation defining a hemispherical cover, as shown in FIGS. 1 &amp; 2. Further, the semi-circular portions have a retracted orientation, wherein each semi-circular portion is in alignment to define a single 30 degree section. Note FIG. 4. It should be noted that the holes of the end are aligned upon the semi-circular portions being in the extended orientation. Next provided is a strap having a pair of ends coupled to the end plates of the semi-circular portions. An intermediate extent of the strap is situated below a seat of a motorcycle. As such, the rigid semi-circular portions are maintained on a rear extent of a seat of the motorcycle. Finally, a locking assembly is mounted on an end plate of an outermost one of the semi-circular portions. The locking assembly preferably includes an inner face with a locking pin adapted to be extended within the holes of the semi-circular portions when in the extended orientation. By this feature, unauthorized access is precluded to a helmet under the hemispherical cover without a key. 
     There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new telescoping motorcycle helmet lock embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     The present invention, designated as numeral 10, includes a plurality of rigid semi-circular portions 12 each defined by a 30 degree section of a full sphere. As shown in FIG. 3, each semi-circular portion has an upper edge and a lower edge each with a lip 14 formed thereon. It should be noted that the lip of the upper edge extends inwardly whereas the lip of the lower edge extends outwardly. A pair of planar, circular end plates 16 are integrally formed on diametrically opposed points on each semi-circular portion. Such end plates are each rotatably mounted with respect to the end plates of the remaining semi-circular sections. Such rotatable coupling may be accomplished by any desired means such as an annular slot and groove combination. For reasons that will soon become apparent, a hole 18 is formed in at least one end plate of each semi-circular portion at a position different from that of the remaining semi-circular portions. 
     In use, the semi-circular portions have an extended orientation defining a hemispherical cover, as shown in FIGS. 1 &amp; 2. Further, the semi-circular portions have a retracted orientation, wherein each semi-circular portion is in alignment to define a single 30 degree section. Note FIG. 4. Preferably, the semicircular portions are adapted to retract rearwardly so as to not interfere with a rider of the motorcycle during use. In other words, the semi-circular portions open towards the front of the motorcycle. It should be noted that the holes of the end are aligned upon the semi-circular portions being in the extended orientation. 
     Next provided is a strap 20 having a pair of ends coupled to the end plates of the semi-circular portions. An intermediate extent of the strap is situated and coupled below a seat of a motorcycle. As such, the rigid semi-circular portions are maintained on a rear extent of a seat of the motorcycle. In the preferred embodiment, the strap is constructed from a metallic material or the like that can not be severed or removed. 
     As shown in FIG. 2, the strap may be situated vertically or at a rearward angle such that the present invention is positioned as far back as possible. It is imperative that it be understood that the present invention is to be mounted as close to the rear of the motorcycle as will be permitted. In the alternative, the present invention may be mounted in other locations on the bike. For example, the semi-circular portions of the present invention may be mounted at a front of the motorcycle and open towards the rear. 
     Finally, a locking assembly 22 is mounted on an end plate of an outermost one of the semi-circular portions. The locking assembly preferably includes an inner face with a locking pin adapted to be extended within the holes of the semi-circular portions when in the extended orientation. By this feature, unauthorized access to a helmet under the hemispherical cover is precluded without a key. During use, the locking pin is adapted to automatically insert within the holes when aligned. Further, the locking pin may be removed by inserting the key within a slot formed in an outer face of the locking assembly and subsequently rotating the same. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, 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, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
