Abstract
ABSTRACT OF THE DISCLOSURE
An eyeglass assembly having removable temple pieces. A
spring arm has on one end a hinge pin and on the other end means for mounting the arm on the temple piece. The arm is shiftable between an advanced position wherein the pin unites the knuckles to form a hinged connection, thereby attaching the temple pieces to the front frame piece, and a retracted position wherein the pin is removed from the knuckles. This detaches the temple pieces from the front frame piece and enables use of the latter separately, for example, in a gas mask where the temple pieces would interfere with the proper placement of the mask.

Description
EYE&LASSES WITH QUICK CONNECT ~ND DISCONNECT
TEMPLE PIECES
BACKGROUND AND GENERAL STATEMENT OF THE INVENTION
This invention relates to eyeglasses with temple pieces which may be quickly connected and disconnected to the front frame piece, as required in a structure such as gas masks where independent use of the front frame piece with its component S lenses is required.
The most commonly used style of eyeglasses comprises a front piece, which includes the lenses, hinged through pin and knuckle hinges to a pair of temple pieces having bows which attach the eyeglasses to the ears of the wearer. However, there are situations in which it ls desirable to use the frame front piece and lenses independently of the temple p~eces.
Such a situation exists in the use of gas masks, which re-quire the mask to fit tightly around the face of the u~er. In such a situation it is not possible for the user to wear eye-glasses of the type described since the temple pieces wouldproject outslde the periphery of the mask and prevent the re-quired tight fit of the mask about the face.

2. ~ L~
The conventional solution to this problem is to provide eyeglasses without temple pieces which attach to the gas mask through an attaching device mounted on the eyeglass bridge.
Such an assembly is illustrated in Wise et al 3,563,640. Al-though this assembly achieves the desired purpose of providingthe gas mask user with eyeglasses which do not interfere with the proper functioning of the ma~k, it forces the user to pur-chase an extra pair of prescrlption glasses, one for use in hls gas mask and the other for ordinary wear, with attendant extra expense.
It is the general object of the present invention to pro-vide an eyeglass assembly having a front frame piece which may be disconnected and connected quickly and easily from the asso-ciated temple pieces~ without damaging either component of the assembly. This makes it possible to use the front piece with associated lenses independentiy, as in a gas mask. It also makes posslble use of the front piece~temple plece assembly in the usual manner when gas mask use is not con~empla~ed.
A further object of the invention ls the provi~ion of an eyeglass assembly having quick connect and disconnect temple pieces, which assembly is non-injurious to the wearer, of in-conspicuous appearance and easily adaptable for use with any of the conventional eyeglasses of the type having a front piece connected to two temple pieces through the agency of knuckle-type hinges.

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION
In the drawings:
Fig. 1 i9 a fragmentary perspective view of the eyeglasses of the invention in a first embodlment;
Fig. 2 is a fragmentary, exploded, perspective view of the eyeglas~es of Fig. 1~ illustrating the manner of connecting and disconnecting the temple pieces to and from the Eront piece;
Figs. 3 and 4 are ~ragmentary perspective views illustrating the eyeglasses of the invention in another embodiment~ with the temple pieces connected to and disconnected from the front piece, ~ ~``
respectively; and Fig. 5 is a fragmentary exploded view of the eyeg7ass assembly of the present invention in a third embodiment.
As shown in the drawings, the eyeglass a~ser~ly to whlch the present invention pertains comprises broadly a front frame piece or "front" indicated generally at 10, to which are hinged a pair of temple pieces, referred to genericall~ as "temp~es", and indicated generally at 12.
The front frame piece includes a pair of lens-supporting frames or rims 14 connected in the usual manner by a bridge 16.
Each of the lens-supporting frames carries on its outer margin a bracket 18 on which is mounted a knuckle hinge component 20.
Temple 12 comprises the usual elongated wire or plastic elongated member 22 which terminates at its outer end in an ear-encircling loop or bow 2~. The temp~e has a sleeve extension 26 which may be fabricated from metal, or provlded with a metal insert. Sleeve:26 mounts knuckle hinge components 28 which mate with knuckle hinge components 20 on the front frame piece with the vpenings through the knuckles reglsterlng in conventional manner. The openings may be internally threaded and designed to receive a threaded pin, not shown, which releasably couples the two parts.
The connecting pin normally is o~ very small dimensions and difficult to insert and remove without magnification and a special appliance. It is the purpose of my invention to provlde removable pin means which renders quick and easy the coupling and uncoupling opera~ions ~o tha~ the front rame piece w~th its lens components may be used independently when th~s is 5 desired, as in the case of a gas mask application One such removable pin means is ~llustrated generally a~
30 in Figs. 1 and 2.
As illustrated, it may be fabricated rom a continuous len-gth of wire or other spring materlal. It comprises an arm 32 which terminates at its ~orward end in a pin 34. The pin lies substantially at right angles to the arm and ~s dlmensioned for reception in hinge knuckles 2~, 28 when the knuckles are in mated position with their respective openings aligned.
Arm 32 is mounted on the temple p-lece through the agency of an integral, reversely-bent, rearward end 36 which may be adherently united or welded to sleeve 26, as indicated at 38.
To facilitate the connecting and disconnecting operations~
arm 32 may be provided with an integral, outwardly extending tab 40 which serves as a finger grip.
To operate the device, spring arm 32 is elevated to its Fig. 2 position, knuckles 20, 28 mated~ and pin 34 inserted into the registering openings in the knuckles. The device then assu-mes its Fig. 1 position, with the temple pieces securely attached to the front frame piece.
~hen it is desired to disconnect the temple pieces, the procedure is reversed. Spring arm 32 is elevated, removing the pin from the hinge knuckles. The two pieces then are separated.
The embodiment of Figs. 3 and 4 is similar, except that different means o~ mounting the spring arm on each temple piece is employed.
In this embodiment the spring pin assembly comprises spring arm 42 having at its forward end ,a pin 44 which liès substantially at right angles to the spring arm, Integrally formed wlth the spring arm and pin is a mounting clip 46 dimensioned for sliding frictional engagement with 10- temple piece 22. Its dimensions are such that it may be slid on and off the temple piece at will. When it is ~n the operative position of Figs. 3, it grips the temple piece and secures the p~n in the connected position. However, it may be flexed to its Fig. 4 position to disconnect the pin from the knuckles when it is desired to disconnect the temple piece from the front frame piece, Still another embodiment of the eyeglass assembly of my inventlon is illustrated in Fig. 5.
In this embodiment the removable pin means comprises a spring arm 48 and an integral pin 50 which in its normal po-sition lies spaced from and substantially parallel to the spring arm. The pin asse~bly is releasably secured to the knuckle in operative position through the agency of a mounting base 52 provided with an aperture 54. The aperture is si2ed to receive the end of pin 50.
Accordingly, the pin assembly may be inserted in the kn-uckle~ and locked in position by lnsertlng the end of pin 50 in base aperture 50 in the manner illustrated ln full line in Flg. 5. However~ it may be sprung and removed to the dashed line position of that figure when separation of the temple piece from the front frame piecé is desired.
