Abstract: A fastener system that includes a fastener, a compression-limiting sleeve, and a retainer which generally retains the compression-limiting sleeve on the fastener. By providing that the compression-limiting sleeve is not staked to the fastener, existing technology can be used, and no extra staking processing step needs to be performed. The fastener may comprise a conventional metal threaded screw or bolt, possibly having a recess in its head for receiving a driver. Preferably, the compression-limiting sleeve is cold headed as opposed to being stamped, and preferably includes a counter bore which assures that an end of the retainer is below an end surface of the compression-limiting sleeve. Preferably, the retainer is formed of a thermoplastic elastomer or another suitable material.

Abstract: A glass door construction set in a pre-existing frame includes glass door leaves made of two or more panes of glass, which define a top edge, a bottom edge, and two lateral edges. The top and bottom edges include a top and bottom rail, respectively, to enhance the structural integrity of the glass door leaves. The lateral edges, however, remain free of the typical perimeter framing required on current glass doors to meet the stringent impact standards. The glass door leaves each include handles on either side of the glass leaves that are interconnected to effectively create a structural equivalent of an I-beam. The handles provide the necessary structural rigidity along a vertical extent to meet impact standards.

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.

Abstract: A pair of rimless eyeglasses are formed with lenses having mounting apertures defined through their structures near both their mutually proximate and mutually remote edges. The mounting wires and mounting apertures are of uniform cross section throughout between the inner and outer surfaces of the lenses. The ends of coupling wires at the bridge and temple pieces are bent back upon themselves to form mounting loops. The ends of the coupling wires at the mounting loops are inserted into the apertures in the lenses. The mounting wires are thereby secured in the apertures by the force of friction. Preferably each mounting aperture is lined with a resilient grommet that conforms to the shape of the aperture and at least partially conforms to the shape of the wire inserted therewithin. The grommets grip the wires and the structure of the lenses at the apertures to stabilize the bridge and temple pieces relative to be lenses.
