This invention relates generally to optical devices for magnifying or enlarging viewed images. More particularly, this invention relates to a relatively lightweight and inexpensive pair of binocular eyeglasses which can be worn comfortably and adjusted easily for use in magnifying observed images, for example, while watching television or observing sporting events or the like.
Optical devices such as telescopes, binoculars, and the like are relatively well known in the art for use in magnifying or enlarging observed images. Such optical devices conventionally include eyepiece and objective lenses mounted within an elongated tubular housing in spaced relation along an optical axis. Adjustment means is normally provided to vary the spacing between the eyepiece and objective lenses to select the range at which images can be viewed in relatively sharp focus.
While prior art binoculars and telescope devices accommodate viewing of images at relatively long-range distances, their use can be cumbersome or inconvenient in some situations. For example, binoculars are commonly used by spectators during sporting events, theatrical or operative productions, and the like to afford a better or close-up view of the event. However, the binoculars tend to be relatively heavy and bulky and are not adapted for direct mounting and wearing upon the viewer's head but instead must be held manually in front of the viewer's eyes. As a result, the viewer tends to observe the event through the binoculars at intermittent intervals and not for any sustained period of time. Moreover, the requirement to look through the tubular housing structure can be distracting to some viewers, resulting in a tendency to avoid use of the binoculars for purposes of avoiding eye fatigue.
In addition, traditional binoculars and/or telescope devices have not been adapted in a convenient and relatively inexpensive form for viewing relatively close-range images, for example, while watching television or the like. However, magnification of television images for easier viewing can be extremely beneficial when the television is relatively small or when the viewer is located at a significant distance from the television. Moreover, magnification of television images can be beneficial to persons having certain vision deficiencies, such as myopia.
Accordingly, the object of the present invention is to provide a relatively simple and relatively inexpensive optical device in the form of binocular eyeglasses which can be worn comfortably and over a prolonged time period, and which includes optical elements for magnification of observed images.
In accordance with the invention, a relatively lightweight pair of binocular eyeglasses is provided for magnification or enlargement of observed images, for example, while watching television or a sporting event or the like. The binocular eyeglasses include optical elements supported upon a relatively simple frame assembly which can be worn in a comfortable manner over an extended time period. The optical elements are adjustable between preset limits for respectively viewing relatively close-range or long-range images in clear focus.
In the preferred form of the invention, the frame assembly for the binocular eyeglasses includes a front frame with a rear panel supporting a pair of eyepiece lenses. The rear panel is joined at its opposite ends to a pair of forwardly projecting side panels to which a pair of adjustable bows are connected to extend rearwardly over the ears of the person wearing the eyeglasses, thereby supporting the eyepiece lenses in fixed positions in front of the viewer's eyes. A front slide panel is carried along a track between the side panels and includes a pair of objective lenses positioned in respective optical alignment with the eyepiece lenses. These objective lenses are selected to have relatively wide angle and relatively low power magnification characteristics.
The eyeglasses include adjustment means including front and rear limit stops defining end limits of fore-aft movement for the front slide panel and objective lenses. More particularly, the front slide panel can be moved forwardly between the frame side panels to contact the front limit stops thereby achieving a close-range focus setting position for clear viewing of images within a relatively close range, such as about six feet to about twenty feet. Alternatively, the slide panel can be displaced rearwardly into contact with the rear limit stops for focusing of relatively long-range images, such as images located at distances greater than about twenty feet. Guide runners on the side panels conveniently cooperate with the front slide panel to maintain optical alignment between the eyepiece and objective lenses. Lock means are provided for securing the slide panel in the selected position of adjustment.
In accordance with further features of the invention, the front frame includes a plurality of forwardly projecting spacer tabs for preventing surface scratching of the objective lenses when the eyeglasses are placed, for example, face down upon a flat surface. In addition, the eyeglasses are adapted for convenient wearing in conjunction with conventional eyeglasses. In this regard, support pins are mounted on the bows to project in inboard directions behind the rear panel of the front frame. These support pins are adjustable in vertical position to rest upon the bows of conventional eyeglasses thereby supporting the binocular eyeglasses in a secure and stable manner. Adjustable ear pieces on the bows may also be provided.
Additional features and advantages of the present invention will become more apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
The accompanying drawings illustrate the invention. In such drawings:
FIG. 1 is a side elevation view depicting use of binocular eyeglasses embodying the novel features of the invention;
FIG. 2 is a front elevation view depicting use of the binocular eyeglasses;
FIG. 3 is an enlarged perspective view illustrating the binocular eyeglasses;
FIG. 4 is a transverse vertical sectional view taken generally on the line 4--4 of FIG. 3, with portions broken away to illustrate construction details of the eyeglasses;
FIG. 5 is a longitudinal vertical sectional view taken generally on the line 5--5 of FIG. 3;
FIG. 6 is a fragmented top plan view of the eyeglasses, with portions broken away to illustrate additional construction details;
FIG. 7 is a fragmented exploded perspective view illustrating assembly of portions of the eyeglasses;
FIG. 8 is a perspective view illustrating adjustment of the eyeglasses in use; as viewed in FIG. 10, the eyepiece and objective lenses 26 and 36 may comprise so-called anamorphic lenses of equivalent focal lengths for magnifying images in one plane only, such as magnification in the horizontal plane. With such modification, the eyeglasses can be used while veiwing viewing television images 80 which have been previously reduced in the horizontal plane from a so-called wide screen motion picture production for broadcast on a standard television 82. The anamorphic lenses enlarge the images in the horizontal plane to provide the viewer with a wide screen effect 84 without impacting the images in the vertical plane.
Other features and advantages are also believed to be apparent to those skilled in the art. Accordingly, no limitation on the invention is intended by way of the description and drawings herein, except as set forth in the appended claims.
