June 8, 1937. F. BIRKENSTEIN 210831287 FRAMES OF SPECTACLES AND THE LIKE A Filed April 25, 1936 'all'.
INVENTOR= Ferdinand Blrkerrslcm By, fiumi/Www. ANW. A
Patented June 8, 1937 Ge A Application April l,The present .invention relates to side arms for theframes of spectacles and the like which are made of any suitable material. Y
Side arms for spectacles are known, the crooked end portion of which press against the side of the face oi the wearer oi' the spectacles by means nof a hinge and a spring provided therein in order to obtain a secure fitting of the frame.
In accordance with the present invention these side parts of the spectacles are considerably sim- 25, 1936, sensi No. 76,424. In
1r May ld, 1935' `pliie'd so that various parts hitherto considered essential, can be eliminated u for instance spiral springs, which are very sensitive and easily damaged, the casing for the spiral springs, bayonettype ttings and similar expensive parts. 'Ihese complicated parts frequently cause trouble in the mechanism which is often subjected to wrong and improper treatment.
The side part of the spectacles, in accordance with the invention, consists oi two parts which may be moved independently to each other and which are connected mether by means of freely movable metallic wire-like members passing through both parts of the side arm. A certain amount of tension provided by the metallic wire presses the curved or crooked end oi' the side arm of the spectacle against the side of the face.
.es regards known constructions of side arms for spectacles embodying metallic wires for strengthening and stifening the frame, the construction ofthe side arm in accordance with the present invention diifers chley therein that a metallic wire is provided which latter has a bending` e'ect. The present invention is further char- 35 acterized in that the metallic wire can move freely in the main part oi' the side arm of the spectacles. A In order that the presentinvention may be clearly understood and readily carried into ef- 4@ fect, I will describe said invention in reference to the accompanying drawing, in which:-
Figure l shows a diagrammatical view of the construction; Fig. 2 shows an enlarged longitudinal section ci a tical construction o the improved side arm; Fig. 3 is a section taken on the line mof Fig. 2; Fig. d snows a modied construction.
The curved end i of the side arm of the spectacles is connected in a freely movable manner to the straight portion of the side arm by means of ametallic wire d, a space 3 being left between the two parts of the side arm. The metallic wirev which can be turned freely in the side arm is held fast in both parts of the'side arm atis out- 55 er ends 5, by means for instance of a hook. In
order not to weaken the side arm of the spectacles at the connecting part 3, such as a collar, ball and socket joint or the like, a sleeve 6 is, for example embodied, as shown in the drawing, which engages in both ends of the two movable parts 5 i and 2 of the side arm in such a manner that one of the ends is freely movable whereby the rigid side part is not weakened at the connection with' the curved end.
A practical form of construction oi such a side 10 arm for spectacles (Fig. 2) which can be built up in the actual process of manufacture in simple manner. 'I'he metallic wire 4 connecting the curved end i and the straight portion 2 of the side arm is freely movable in the outer protect- 15 ing casing and 'i and held fast in said casing at 5 by being bent round, pressed together, soldered or otherwise. The protecting case may be covered partly or wholly. In order to obtain a clean connection between the curved end and the 20 straight portion a metallic member 9 is provided in which rests, freely movable, the metallic head I. In order to limit the movement of the curved end an abutment is provided which, by way of example, is represented by a nose or projection 8 25 which, in the drawing, has a protecting casing l,
a segment striking against said projection 8.
The segment is formed by removing a part of the surface oi the sleeve This sleeve is surrounded by a second protecting casing on which 30 the nose or projection 8 is formed or filled. The casing l is enclosed in the outer casing 2.
In the constructional form shown at Fig. 4, by way of example, the casing for the curved end i can be exchanged, the metallic wire t being provided with screw threads Ii to receive a screw threaded member i2 which, when screwed up keeps the casing in the desired position. Fig. shows the end portion of a side arm in accordance with Figs. 1 and 2 but not yet bent. o
It will be understood that the details may be modied without exceeding the scope of the present invention.` For instance, the, connecting wire may consist of several strands of wire twisted or spun together.
1. A side arm for spectacles comprising a stationary part having a longitudinal bore therein, a movable curved part also having a longitudinal bore therein, said curved part being adapt- 5o ed to t behind the ear, and `a resilient wire connecting said parts, freely mounted in said. bores, one end ofsaid wire being fastened to the stationary part and the other to the movable part, said parts and the wire being co-axialiy si mounted, the connections of the wire and the side arms beingrexnote from the junction between said parts,I the outer part ofthe side arm being rotatable only about the common axis of the parts to torsion the wire.
2. A side arm for spectacles comprising a stationary part, a sleeve mountedtherein having a longitudinal bore, a movable curved part', another sleeve mounted therein also having a 1ongitudinal bore, said movable curved part tting behind the ear, and a resilient wire connecting said parts mounted co-axially in said bores, one end of said wire being'connected to the station- `ary part, theother end of said wirebeing connected to the movablepart, the connections vbe' tween said parts and the wire ends being remote from the Junction between the parts, said parts being co-axial, the outer part of the side arm being rotatable onlyabout the common axis of the parts to torsion the wire.
3, Aside arm for spectacles lcomprising a sta'- i tionary part having a longitudinal bore therein, a bearing member on the end of said stationary part, a movable part also having a lonear, a resilient wire connecting said parts together,` the bearing members contacting. said wire being coaxially mounted in said bores, one end of said wire being connected .to the stationary part and the other end to the.movable part, the wire endsbeing connected remote from the junction between the parts and the outer .part being rotatable only about the common axis o1' the parts, the -wire being tortioned for pressing the curved part against the side oi' the head.
4. A side arm for spectacles comprising a stationary part having a longitudinal bore therey its length in, said bores, one end of said wire being connected to the stationary part, the other end to the movable part, and a sleeve mounted inthe ends of the stationary and movable parts to strengthen the junction thereof, the connections between the parts and the wire ends being remote from the junction of said parts. said parts and the wire being co-axially mounted, the
'outer part being rotatable only about the common axis' of the parts to put the wire under tension to cause the movable curved part to press against the side of thehead. Y I
