BACKGROUND OF THE INVENTION

This invention relates to a novel cleaning device for eyeglasses, which is always able to be taken along and is usable at any time. Wearers of eyeglasses know the fact how often a day the glasses are dimmed so for instance by an unintended touching of the glasses or as a result of temperature differences. The contamination of the glasses is often so heavy that only a washing with water and a subsequent drying by rubbing helps.

SUMMARY OF THE INVENTION

It is, therefore, an object of the present invention to provide a cleaning device for eyeglasses by means of which a wearer of glasses is able to effect a thorough cleaning of the glasses in the office or at home at any time, said cleaning device being in the form of a small implement which can be carried in a pocket and has generally the size of a lighter.

To attain this object the present invention provides a cleaning device for eyeglasses which comprises an elongated casing having a circumferentially closed wall and open ends; removable upper and lower lids for closing said ends; a guide member conformed to the inner shape of the casing and longitudinally slidable therein, said guide member having a rearwardly extending projection; a conduit extending through the guide member and the projection; two oppositely arranged resilient limbs extending forwardly from the guide member and having free ends carrying retainers, each of said limbs being adapted to grip in the extended position of the limbs around the edge of a spectacle lens; sponge-like wipers replaceably connected to the retainers at the free ends of the resilient limbs; conduits extending longitudinally through the limbs and communicating with the conduit in the guide member and in the rearwardly extending projection; a film bag detachably attached to the rearwardly extending projection and filled with a liquid cleaning agent, and two diaphragms provided in the wall of the casing and adapted to be pressed in the extended position of the limbs and the wipers so as to cause the film bag to dropwise emit cleaning agent via the conduit in the guide member and in the projection, the conduits in the limbs and in the wipers to the spectacle lens.

BRIEF DESCRIPTION OF THE DRAWING

A preferred embodiment of the invention will now be described by way of example and with reference to the accompanying drawing, in which:

FIG. 1 is a front elevational view of a cleaining device for eyeglasses when not in use;

FIG. 1a is a sectional side view of the cleaning device with the wipers extended and the upper lid removed;

FIG. 1b is a front-elevational view, partly in section of the cleaning device in operation, and

FIG. 1c is a top plan view of FIG. 1a.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The drawing shows a pair of disc-shaped sponge-like wipers 1 which are detachably connected to the free ends of resilient limbs 2 which at their opposite ends are connected to a guide member 2a conformed to the inner shape of an elongated casing 4 in which is is slidably guided in the longitudinal direction thereof. The casing 4 may be of circular, oval, rectangular or substantially rectangular cross section. The guide member 2a at its bottom has a rearwardly extending projection 2d which defines a conduit and serves for detachably receiving a film bag 5 filled with a liquid cleaning agent W. The conduit 2e in the projection 2d extends also transversely in the guide member 2a and communicates with two further conduits 2b defined by the limbs 2 and merging at their forward ends into nozzles 2c located directly adjacent to the wipers 1 as shown in FIG. 1a.

FIG. 1a also shows two oppositely arranged diaphragms 6 which may be formed integral with the wall of the casing 4 by thinning the casing wall or may be in the form of thin discs of a resilient material inserted and fixed by means of an adhesive in openings cut into the casing wall. The film bag 5 is operable from externally by pressing upon the diaphragms 6 for the purpose of emitting cleaning agent via the conduits 2b and the nozzles 2c to the glasses.

The cleaning device further comprises as shown in FIG. 1 two retainers 2' for the wipers 1, an upper closing lid 3, a lower closing lid 7, two spare wipers 8 in the lower closing lid. B is a representation of eyeglasses.

When the lower closing lid 7 has been removed, the wipers 1, the limbs 2, the guide member 2a and the film bag 5 may be pulled rearwardly outwardly from the casing 4 in order to e.g. refill the film bag 5 or in order to exchange the wipers 1.

The invention may be embodied in other specific forms without departing from the spirit of essential characteristics thereof. The embodiment is therefore to be considered in all respects as illustrative and not restrictive.
