Description
Background of the Invention
1. Field of the Invention
The field of invention relates to eyeglass apparatus, and more particularly pertians to a new and improved adjustable spectacle leg apparatus wherein the same includes earpiece legs adjustably mounted relative to each temple leg.
2. Description of the Prior Art
Accommodating various cranial geometries of individuals to receive eyeglass frames thereon requires time consuming and labor intensive procedures. Further, conventional eyeglass assemblies during normal usage are frequently dropped, deformed, exposed to sun, depressed temperatures and the like to alter the geometric configuration and integrity of an eyeglass assembly. Positioning of an eyeglass assembly relative to an individual is a significant and important aspect in the proper alignment of the eyeglass assembly relative to an individual's focal orientation, as well as to minimize damage due to improperly mounted eyeglass organizations.
Prior art structure to address these problems has been exemplified in U.S. Pat. No. 4,844,605 to Peterson, et al. wherein an auxiliary earpiece is mounted relative to each temple leg of an eyeglass assembly for securement to an individual.
U.S. Pat. No. 4,732,465 to Field sets forth an eyeglass holder wherein flexible sheets are directed through each earpiece to enhance securement of each earpiece to an individual.
U.S. Pat. No. 4,925,291 to Anger, et al. sets forth a readily deformable earpiece leg.
As such, it may be appreciated that there continues to be a need for a new and improved adjustable spectacle leg apparatus as set forth by the instant invention which address both the problems of ease of use as well as effectiveness in construction and in this respect, the present invention substantially fulfills this need.
Summary of the Invention
In view of the foregoing disadvantages inherent in the known types of eyeglass apparatus now present in the prior art, the present invention provides an adjustable spectacle leg apparatus wherein the same includes an adjustable earpiece mounted to a temple leg to permit longitudinal adjustment of the earpiece relative to an associated temple leg. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved adjustable spectacle leg apparatus which has all the advantages of the prior art eyeglass apparatus and none of the disadvantages.
To attain this, the present invention provides an eyeglass assembly including a rim organization to mount spectacle lenses therewithin pivotally mounting a plurality of temple legs, with a temple leg pivotally mounted at each end of the rim organization. The temple legs each include an arcuate earpiece leg that mounts an internally threaded rod rotatably received within an internally threaded bore formed longitudinally of each terminal end of each temple leg to permit adjustment of each earpiece leg relative to each temple leg.
My invention resides not in any one of these features per se, but rather in the particular combination of all of them herein disclosed and claimed and it is distinguished from the prior art in this particular combination of all of its structures for the functions specified.
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.
