Description
- L. H. KLEIN NOSE PAD GUARD MOUNTING CONSTRUCTION May 4, 193 7.
Filed Aug. 2, 1935 Patented May 4, 1937 UNITED STATES PATENT OFFICE Louis H. Klein, Chicago, Ill.
Application August 2,
2 Claims.
My invention relates to a nose pad guard mounting construction for frames or mountings for eye glasses.
One of the objects of my invention is to provide a mounting for the guard which will permit of a suitable automatic adjustment of the guard to the wearer.
A further object is to provide such a construction in which the adjustment will permit of a limited tilting self-adjustment of the guard in two directions and which will cause the guard to exert a substantially even pressure throughout its extent.
Further objects and advantages of the invention will be apparent from the description and claims.
In the drawing, in which two forms of my invention are shown,
Figure 1 is a rear view of a pair of eye glasses provided with my improved nose pad guard mounting;
Fig. 2 is an enlarged detail view of the guard and bow spring;
Fig. 3 is an enlarged side view of the guard and mounting, parts being broken away;
Fig. 4 is a view similar to Fig. 3, but showing the bow spring compressed as it might be when worn;
Fig. 5 is a somewhat enlarged perspective view showing the mounting bracket and lens frame; and
Fig. 6 is a view similar to Fig. 3, but showing a different form of mounting.
Referring to the drawing in detail, and first to Figs. 1 to 5, inclusive, the construction shown comprises the lens frames I, in which the lenses 2 are mounted, the bridge 3 connecting the frames l, the bows 4 pivot-ally connected with the frames, and the guards 5, here shown as mounted on brackets 6 secured to the lens frames I. The mounting for the guard comprises the curved bracket member 6 brazed or otherwise suitably secured to the lens frame i and extending generally rearwardly and thence downwardly therefrom, as shown in Fig. 5, a non-circular pin 1 loosely fitting in an opening in a flattened portion of the bracket 6 so as to be able to tilt slightly in any direction and slide in said opening, and a pair of bow springs 8 and 9 having openings through which the pin 1 extends and having their central portions spaced from each other and their ends in engagement with each other. These bow springs are so tensioned thatv they tend to hold the guard in the position shown in Fig. 3 but will permit the guard 5 to be forced toward the bracket 6, as shown in Fi 4, when in use. The
1935, Serial No. 34,365
shape of the bow spring also enables the guard to tilt by a rocking movement of the bow spring 8 on the fiat portion of the bracket so as to accommodate itself to the wearer. The bow spring exerts a substantially equal pressure on both ends of the guard to cause an even pressure of the guard on the nose. The yielding spring construction relieves the pressure and cushions the action of the guard. The guard is held in position on the bracket against the action of the springs by means of a washer l0 underneath the head of the pin which will engage the flat portion of the bracket when the glasses are not in use, as shown in Fig. 3. By referring to Fig. 3, it will be seen that the bow spring acts as a sort of rocker, engaging the flattened portion of the bracket to enable the guard to rock readily to accommodate itself to the nose.
The construction of Fig. 6 is similar to that just described, except that in this form the leaf spring which engages the guard is backed up by a small coil compression spring I l between the bow spring and the flattened portion of the bracket.
Further modifications will be apparent to those skilled in the art, and it is desired, therefore, that the invention be limited only by the prior art and the scope of the appended claims.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. A lens mounting construction for eye glasses and spectacles comprising a guard supporting bracket having means for securing it in position with respect to the lens, a guard, and means for adjustably mounting said guard on said bracket, said bracket having an opening therethrough, and said mounting means comprising a pin secured to said guard slidably and tiltably but nonrotatably mounted in said opening, and a bow spring having an opening through which said pin extends, the ends of which spring exert pressure on the guard tending to hold it away from the bracket, said bow spring having an intermediate curved portion and said bracket having a substantially flat surface extending a substantial distance on both sides of the opening on which surface the intermediate curved portion of the spring may rock with a chair rocker action to bring different parts of the curved portion of the spring into engagement with said flat surface, thereby shifting the effective fulcrum about which the bow spring rocks to enable the guard to adjust itself to the wearer, the extent of the fiat surface on which the spring may rock being at least three times the extent of the opening through which said pin extends.
2. A lens mounting construction for eye glasses and spectacles comprising a guard supporting bracket having means for securing it in position with respect to the lens, a guard, and means for adjustably mounting said guard on said bracket, said bracket having an opening therethrough, and said mounting means comprising a pin secured to said guard slidably and tiltably but non-rotatably mounted in said opening, and a pair of bow springs having openings through which said pin extends, said springs having their middle portions spaced from each other and their ends in engagement with each other and exerting pressure on the guard, one of said bow springs having an intermediate curved portion and said bracket having a substantially flat surface extending a substantial distance on both sides of the pin on which surface the intermediate curved portion of the spring may rock with a chair rocker action to bring difierent parts of the curved portion of the spring into engagement with said fiat surface, thereby shifting the effective fulcrum about which the bow spring rocks 1 to enable the guard to adjust itself to the wearer.
