N A H T A N K E SHIFTABLE SPECTACLE Filed July 29, 1952 ATTORNEY United States Patent C) SHIFTABLE SPECTACLE Elizabeth K. Nathan, New Hope, Pa.
Application July 29, 1952, Serial No. 301,430
2 Claims. (Cl. 885 1) This invention is concerned with improvements in womens spectacles; particularly for users whose eyesight require an occasional aid and who, therefore, must keep them handy. To that end, they usually keep them in a pocket, or attached to the garment or person by a cord, hook, or the like. This is not only troublesome but may permit them to be lost or brushed off. As an alternative, bi-focal lens have been worn constantly.
To obviate all of such inconveniences, this invention proposes a construction that, during periods of non-usage, the spectacles may be retained by a tuft of hair against the side of the head somewhat above the ear and more or less rearward thereof; the whole being folded zig-zag to lie flat and out of the way, but always immediately available by being easily unfolded to shift the lens member onto the bridge of the nose for usage without, however, disturbing the position of the catch or gripper for the tuft of hair. The catch then will hold the temple-bar to enable it to steady the lens member on the nose in proper position.
The novel construction for attaining this objective is shown in the accompanying drawings, in which:
Fig. l is a side view showing the location of the device when folded zig-zag fiatwise against the side of the head when the user requires no optical aid.
Fig. 2 shows the device partially unfolded and about to have its lens-frame placed on the nose.
Fig. 3 shows the device in placement for usage with the lens-frame resting on the bridge of the nose; the whole being sufliciently steadied by the single temple-bar. This is adequate because of its permanent attachment to the hair clasp.
Fig. 4 is a plan of the device partially unfolded to show the jaws of the hair clasp opened preparatory to gripping a tuft of hair when about to be mounted for the day at the side of ones head.
Fig. 5 is a similar view of the device up-side down.
In general, the spectacle consists of three major elements; first, the lens-frame A characterized by having hinged thereto a single temple bar; second, the single temple-bar B characterized by having its remote end permanently hinged to a hair-clasp; and third, the hair-clasp C which embodies two meshing jaws for gripping a tuft of hair.
The hair-clasp C comprises per se a body-portion 1; preferably in the form of an ornamental brooch of the sort common in costume jewelry. In this case, the brooch is provided with a first hinged attachment 2 to the solitary temple-bar B. This hinge 2 is such as will enable the temple-bar to lie fiat-wise against the outer face of the brooch (during the non-use time) or in alignment with the plane thereof during the interval of optical aid.
The rear face of the body-portion also is provided with a jaw-member 3 immovably affixed thereto, and which in turn is formed with rearwardly projecting teeth or corrugations 4. A second jaw-member 4 is hinged at 5 to the body-portion and likewise is provided with complementary teeth or corrugations 6 so that, when swung against the other jaw-member 3, the respective teeth will inter-mesh with ample spaces for the strands of hair and thereby hold the unit in place where desired at the side of the head as shown. To hold the jaws closed, any convenient means, such as a small catch 7, is desirable.
The temple-bar B, as aforesaid, is hinged in a convenient manner to the lens-frame A; it being particularly noted, however, that the hinge at its rear extremity is arranged reversely to the forward hinge. This characteristic feature is important in that it enables a zig-zag folding of the three elements into compact form close to the side of the head to be out of the way but yet instantly available when desired to bring the lens before the eyes; all by merely grasping with one hand the lens-frame and shifting it to rest on the bridge of the nose.
1. A spectacle comprising a lens-frame; a single templebar; a hair clip; a first hinge connecting one side-edge of the lens-frame to the forward end and inner side of the temple-bar; and a second hinge connecting an outer sideedge of the hair-clip to the rear end of the temple-bar at the outer side thereof; thereby enabling the frame, the bar and the hair-clip to be folded zig-zag into compact form.
2. A spectacle according to claim 1 in which the inner face of the hair-clip provides a corrugated jaw, and a second jaw hinged to the inner face of the hair-clip and provides corrugations loosely meshing with those of the other jaw.
