Description
Background of the Invention
1. Field of the Invention
This invention relates in general to a glare eliminating device and in particular to means which provides for substantial universal adjustment and for easy out of the way storage.
2. Description of the Prior Art
It has always been desirable to provide for a motorist an effective sun and/or headlight shield, having a cross sectional area sufficiently large enough to obscure the objectional rays, but yet small in size as to not obstruct the driver's clear view of the road. The conventional large size fold-down visor is not adequate because of its tendency to obscure such a great portion of a driver's view in attempting to screen out the rays of the sun.
To eliminate glare effecting a motorist from either the sun or from the headlights of on-coming cars, devices, other than conventional visors, have been suggested. Examples of these devices are disclosed in U.S. Pat. Nos. 2,878,714 and 3,261,638. Such devices have been relatively complicated and have had a plurality of spaced shielding areas requiring more than a simple touch of the hand for adjustment. While many previous devices were adjustable to some extent, they were generally characterized by a limited range of adjustment. Thus, these models, which offered only limited adjustment capabilities, left the driver with substantial visual areas where glare from the sun could still be hazardous to safe driving. Likewise, most of these devices required permanent affixation and/or were not readily movable from the initial setting while the vehicle was in motion, and were not readily storable permitting for free access and use of the existing conventional visor.
Reference is made to my U.S. Pat. No. 3,940,180 wherein the disclosed mounting means consisted of a length of hook-type pressure sensitive releasably-engaging cloth materials such as commonly sold under the Trademark VELCRO, affixed by an adhesive along the inner windshield molding or the like and on the bottom of the mounting bracket. An increasing number of foreign and domestic vehicles have inner windshield moldings made of rubber and other materials which reject pressure sensitive adhesives. Likewise, in extreme heat the material occasionally tends to separate from the windshield molding or from the bottom of the mounting bracket.
Summary of the Invention
The present invention is directed to a glare eliminating device, which is simple, easy to install, inexpensive, readily adjustable and storable. It as well eliminates affixation by use of an adhesive.
To accomplish these results, the invention comprises a glare eliminating device including a support arm, a flat shielding portion of an opaque material pivotally attached at its center to one end of said support arm, and a mounting means pivotally attached to the other end of said support arm, said mounting means of a resilient or thermoplastic material found as a one piece member having a bight portion interconnecting a pair of legs having means for gripping formed on the ends thereof, said bight portion resiliently urging the ends of said legs towards each other so that the means for gripping formed on the ends of said legs will tightly engage the leading edge portion of the usual vehicle sun-visor inserted therebetween.
Brief Description of the Drawings
Other objects, features and advantages of the invention, together with its organization, construction and operation will be best understood from the following detailed description of a preferred embodiment of the invention, taken in conjunction with the accompanying drawings, on which:
FIG. 1 is a pictorial representation of the view blocked by conventional visors and that of the device of the present invention illustrating its in use and storage positions;
FIG. 2 is a frontal view of the present invention showing the radially adjustable feature;
FIG. 3 is a side view;
FIG. 4 is a pictorial representation of the present invention in a stored position; and
FIG. 5 is a perspective view of the present invention.
Description of the Preferred Embodiment
Referring to FIG. 1, a storable glare eliminating device indicated generally by the reference numeral 10 including a shielding portion 11 having a rectangular shape with rounded corners of the approximate dimension of 4.5 inches in length and 2.25 inches width. The shape of the shielding portion 11, as best illustrated in FIG. 2, is chosen with the dimension X equalling about 2.5 inches, approximating an average eye-to-pupil distance to completely block the objectionable glare from impinging upon the eyes of the motorist, while leaving unobstructed the greatest possible field of vision. As a result of the optical phenomenon referred to as "Binocular Diplopia" occurring under normal vision, the shielding portion 11 will be reduced, in the mind of the motorist, to a black, generally circular-shaped spot of approximately one-half the width of the shielding portion 11, which spot covers the sun effectively for both eyes.
The support arm 14 is approximately 0.5 inch wide and 6 inches long. The shielding portion is pivotally attached by means of a rivet 12 and steel spring or Neoprene washer 13 to one end of the support arm 14. The other end of the support arm 14 is pivotally attached by means of a rivet 15 and a spring or Neoprene washer 16 to a mounting means 17 at approximately the center of its bight portion 18. The configuration of the mounting means 17 is best seen in FIG. 5. The rivet 15 and the spring or Neoprene washer 16 provide sufficient frictional engagement between the support arm 14 and the mounting means 17 to retain the selected relative positions of the support arm 14 and the mounting means 17 after adjustment. A similar frictional engagement is provided by the rivet 12 and the spring or Neoprene washer 13 between the shielding portion 11 and the support arm 14.
The mounting means 17 is preferably formed from a tough thermoplastic material such as for example ABS (a copolymer of acrylonitrile, butadiene and styrene), which will adapt to the thickness of the item to which it is attached in approximately 24 hours and remain tightly resiliently engaged thereto. The mounting means 17, as best illustrated in FIG. 5, is comprised of a bight portion 18 with an ID radius of about 1/3 inch interconnecting a pair of legs, 19 and 20, having means for gripping formed on the ends thereof, flanges 21 and 22, respectively. Leg 20 is approximately 2.5 inches wide and 2 inches long, and leg 19 is approximately 2.5 inches wide and 1.75 inches long. The gripping means, ribs or flanges 21 and 22, have a length of approximately 0.25 inch and extend the width of the legs, approximately 2.5 inches, and perpendicular thereto. The gripping means, flanges 21 and 22, overlap as a result of the 0.25 inch difference in the lengths of the legs 19 and 20.
Two visor-engaging ribs 23 are provided on the interior surface of each leg 19 and 20 having an approximate height of 1/32 inch which run parallel to the flanges for the width of the legs.
FIG. 1 illustrates that the storable glare eliminating device constructed in accordance with the present invention will effectively screen objectionable glare from the driver with absolute minimum obstruction of the area required by a conventional sun visor 24 (as indicated by the dotted lines) while at the same time providing for a convenient method of storage, wherein the support arm 14 and shielding portion 11 are pushed up parallel with the leading edge of the vehicle visor (as indicated by the dotted line configuration), while allowing the regular up and down use of the automobile visor without interference therewith. The stored position is more specifically illustrated in FIG. 4. As can be seen from FIGS. 3 and 4, the shield 11 is stored slightly ahead, or in front of the regular visor in a manner perpendicular to visor 11, permitting ordinary pivotal rise even though the visor is tilted downwardly. Thus, the relatively simple device may be placed completely out of use in the storage condition in which it does not interfere in any way with conventional automobile operation.
Variations may be made without departing from the novel concepts of my invention, it is therefore intended that the scope of the invention be limited solely by the hereinafter appended claims.
