Abstract: A buckling device for fastening a belt is provided. The buckling device comprises a first portion, a second portion and an elastic portion. The elastic portion is made of a material with a shore hardness substantially between A10 and A95. The elastic portion contacts the first portion and the second portion, so that the second portion engages with the belt and the belt is fastened.

Abstract: The present invention relates to the rimless spectacles with lens holding stability, the jointing condition between the respective lenses and the parts to be engaged thereto of which spectacles is very stable and which shape stability lasts for a long period of time. Such rimless spectacles is provided as not only being stable in the jointing condition between the respective lenses and the parts to be engaged thereto so as to keep its shape intact for a long period of time and simplifying the number of the assembly parts so as to be advantageous for the parts inventory control as well as the maintenance thereof, but also improving the production efficiency thereof.

Abstract: Fastening means for attaching eyeglass members together includes a barbed locking pin inserted into a bushing. More particularly, rimless eyeglasses require new technology to render them long-lasting and fail-safe. Said unique means of attachment is a highly effective replacement for the typical screw attachment means in many eyeglass configurations, including rimless and rimmed versions. In one embodiment, the barbed pin is inserted into the bushing such that the barbs restrict removal. The barbs can be spaced circumferentially along a length of the pin or can be intermittently distributed along the pin. In another embodiment, co-planer barbs along the pin create additional sharp corners to facilitate a connection between the pin and bushing. In a preferred embodiment the barbs are metal. The invention disclosed facilitates fail-safe attachment of eyeglass members together including a temple hinge mounting-bracket to a temple or lens and a bridge member to a pair of lenses.

Abstract: Disclosed is an eyewear retention system, which extends across the top of the wearer's head for supporting at least one lens in the wearer's field of view. The retention system includes at least a first and a second support component, which are spaced apart laterally from each other along at least a portion of the eyewear system. The system may include any of a variety of electronics, including telecommunications receivers, transmitters, electronic storage devices, and head-up display driving circuitry.
