The securing ring has a channel therethrough which includes a series of projections. An additional series of projections are formed on the barrel of the pin. Thus, when the pin is mounted within the frame of the glasses, the securing means is placed over the barrel so that the projections within the securing ring and the projections on the barrel cooperatively interact to permanently secure the pin assembly into the eyeglasses frame. This also insures that the lens is permanently mounted within the eyeglasses frame. The projections on the barrel of the pin and within the securing ring are oriented such that the user can slide the ring onto the barrel of the pin but can not remove the ring once the projections come in contact with each other.

Abstract: A portable loudspeaker system that includes loudspeaker means for reproducing relatively high audio frequencies, and amplifier means, and further includes a carrying case formed as a relatively rigid, low-density, releasably matable pair of polystyrene shells that define an enclosed interior space when mated. Mounted in an opening through a wall of one of the shells is a woofer for reproducing only relatively low audio frequencies as acoustic waves radiating away from said case. Disposed within the case is a body of sound absorbing polyurethane foam that has a plurality of relatively large voids for respectively storing the loudspeaker means, the amplifier means and an optional sound source such as a compact disc player.

Abstract: This invention relates to an eyeglass frame comprising members, particularly hinge members, which are connected by a screw joint which is protected from becoming loose. The screw joint comprises a single metal part, which consists of a screw, which does not tend to become seized and to become clamped in the relatively movable hinge eyes. Because plastic parts are not required in the joint, the screw may remain installed during soldering work. This is accomplished in that the screw has a conical head portion which tapers with an included angle of 20 to 40 degrees, preferably 30.degree., and when the screw has been screwed into the frame the head of the screw extends in a conical opening in a member of the frame and in said opening defines with said frame member a clearance angle of 1 to 3 degrees and a clearance space axially adjoining the head. In such a joint the screw can firmly be tightened so that the high friction will prevent the screw from becoming loose spontaneously.
