Abstract: There is described an apparatus and a fixture used in determining position and for producing assembling holes in a spectacle lens for rimless spectacles. The assembling holes are intended for receiving a U-shaped bracket which is used in fastening bridge and side bar hinge. The apparatus and fixture includes interacting guide pins and guide holes. These guide holes/pins are unambiguously disposed. The guide holes will preferably be placed symmetrically in relation to a hole center line for the lens, when this is placed in the fixation opening of the fixture with the hole center line disposed opposite to markings at the fixation opening. The assembling holes are thus placed symmetrically in relation to the marking. By such a system it is possible to make rimless spectacles that appear very accurate, without special skilled qualifications on the part of the optician to make assembling holes in the lenses.

Abstract: An eyeglass frame comprises a frame front, a pair of temple bars and a hinge for each temple bar to provide a pivotal connection. The hinge comprises a coil winding of a resilient wire integral with the temple bar and a body with a threaded groove integral with the other one of the frame front or temple bar. The body comprises friction material and the coil is adapted for cooperating and pretensioned engagement with the body in order to provide a pivotal connection with a controlled friction resistance to turning of the pivot. The invention a so provides a hinge, an eyeglass and a method of manufacturing a hinge.

Abstract: A pair of spectacles comprises two support elements (7) for engaging the nose of the wearer. Each support element comprises a pad (8) of an elastic material, a reinforcement member (22) and a peg (13) adapted for being received in the eyelet. The reinforcement member and the peg are adapted for mutual snap fitting engagement. The peg relieves the pad of any tensile forces and makes it feasible to select for the pad a very soft and comfortable material. Easy mounting and safe retention are provided. The invention further comprises a blank for the manufacturing of the peg, and a method of manufacturing a pair of spectacles.

Abstract: A pair of spectacles comprises two support elements (7) for engaging the nose of the wearer. Each support element comprises a pad (8) of an elastic material secured to a shank (10) with an enlarged head (11) adapted for retaining the support element relative to the rest of the spectacles by way of inserting the shank through said eyelet of the frame. According to the invention a peg (13) is inserted into the head end of the shank for providing a hard core inside at least part of the shank. Thus, easy mounting and safe retention are provided. The invention further comprises a blank for the manufacturing of the peg, and a method of manufacturing a pair of spectacles.

Abstract: An eyeglass frame comprising a frame front, a pair of temple bars and respective hinge means, adapted to provide a pivotal connection of each temple bar with the frame front. According to the invention each hinge means comprises a cooperating pair of friction members (13,15) and a spring means (13) adapted for applying balanced, radially directed biasing forces onto the cooperating pair of frictions members. Hereby any play in the hinge is eliminated and the friction is maintained. Further the invention provides an eyeglass and a method of manufacturing an eyeglass.

Abstract: A shield (2) for selective fitting on a pair of spectacles (2) comprises shield glasses, a shield frame and shield guide faces (8). The spectacles comprise a spectacle frame with frame guide faces (3, 19, 20), which are oriented generally perpendicular to or in an oblique direction relative to the spectacle glasses. The spectacle guide faces and the shield guide faces are adapted to permit sliding the shield into a secured position, while preserving the mutual orientation of the shield and the glasses during a final stage of approach.

Abstract: A clip-on shield (6) for spectacles (1) adapted for securing shield lenses (7) in front of the lenses (4) of the spectacles is provided with a connecting bridge (8) between the lenses provided with an engagement tongue (12) that engages behind the connecting bridge (3) of the spectacles, and is designed to transmit force from the shield which is oriented centrally relative to the symmetrical plane of the spectacles. The shield is guided by the abutment of a friction surface at each shield lens on the front of the spectacles and optionally by a guide pin (9) at each shield lens, said guide pin engaging with the spectacles. A spring means is arranged to bias the engagement tongue against the back of the spectacle's connecting bridge and the shield lenses towards the front of the frame of the spectacles.

Abstract: The closing of tubular casings containing foodstuffs by mounting a binder on a constriction of the casing involves the traditional problem of a high waste percentage due to the binders either damaging the casing material or sliding off the constriction. A method and a binder are proposed which makes it possible to obtain a very strong clamping of the binder without damaging the casing material, and, in connection with tight plastic casings, it is even possible to provide a "super tight" closure, by ranging the constriction with an oblong cross section between opposed straight clamping beams, which are forced together so as to produce a controlled deformation flowing of the casing material.
