  • Patent number: 5696572
    Abstract: A retainer for securing a nose pad on an eyeglasses frame, the retainer being composed of a flat, one-piece pad arm having a receiving opening in the form of an elongated hole, and a retaining element of plastic secured to the nose pad, the retaining element having a constriction and being receivable in the receiving opening of the pad arm to be locked in the receiving opening by engagement of the constriction in the opening. The pad arm is a bilaterally symmetrical structure having a first end in which the opening is formed, is made of material which extends continuously around the opening and is substantially inelastic around the opening. The opening cross section of the elongated hole is selected and the retaining element is formed such that when the constriction engages in the receiving opening, a transition surface of the retaining element is engageable with the pad arm for allowing the retaining element and the nose pad to be pivotable and tiltable relative to the pad arm.

  • Patent number: 5351099
    Abstract: A support arm with a holder for a bearing element such as a nose pad for fastening the holder to a respective frame of eyeglasses. The support arm is constituted, along at least a portion of its length, by a core of hard material and inner and an outer layer of wires wound spirally as a jacket around the core. Because of this combination of materials, the support arm has both adequate stability in the normal position when the glasses are worn by the glasses wearer and also flexible resiliency and ensuing restoration of the normal position in the event of an external strain such as an impact, without permanent deformation of the support arm.

  • Patent number: 5200771
    Abstract: In a pair of eyeglasses having a bridge joining the edges of the lenses, the nose rest includes a one-piece bow which is secured via a spacer element to a retaining and essentially rests only on the bridge of the nose. In particular, the bow, spacer element and retaining plate are portions of a one-piece shaped part, so that a wider range of adaptation options to the individual anatomical features of the eyeglasses wearer in the nose region, on the one hand, and to the eyeglasses design used, on the other hand, is possible in a simple manner.

  • Patent number: 4904076
    Abstract: A nose pad adapted to be attached to a spectacle frame to form a part thereof. The nose pad has a relatively hard base body, a relatively soft, skin-friendly and slip-resistant covering on the base body and a securing arrangement affixed to the base body and projected from the covering for connecting the nose pad to the spectacle frame. The securing arrangement comprises a plurality of spaced anchoring pins adapted to be directly received by respective bores provided in a front piece of the spectacle frame. At least one of the anchoring pins has a pulling force-resistant device for resisting a separation of the nose pad from the spectacle frame by forces applied to the nose pad and directed away from the spectacle frame.
