Abstract: A pair of eyeglasses includes an eyeglass frame and a lens unit mounted detachably on the eyeglass frame. The eyeglass frame includes a curved front frame with two downwardly projecting end portions, and two bows. The curved front frame has an engagement groove formed therein, and a retained portion disposed at the middle section of the curved front frame. The engagement groove has two end portions respectively extending into the front surfaces of the downwardly projecting end portions of the curved front frame. The lens unit includes two lenses and a plastic lens rim mounted securely on the lenses. The lens rim has a rib projecting upward from the upper end portion thereof so as to engage the engagement groove. The rib has two lugs projecting respectively and outwardly from two ends thereof and being inserted into the end portions of the engagement groove. A hook is fixed on the lens rim and has a retaining space formed therein so as to retain the retained portion of the curved front frame.

Abstract: An improved pair of swim goggles, especially designed for competitive swimming, is comprised of two substantially ovoid, convex lenses secured to a soft neoprene base. The goggles are simply and easily tightened about the head by a one pull toggle mechanism that provides an equal, balanced fit of the eye pieces against the face. The goggles provide less hydrodynamic resistance in the water during swimming and not only reduces fatigue by cutting down on eye strain but allows the swimmer both superior frontal and peripheral vision.

Abstract: The present invention relates to eyeglasses and, more particularly, to eyeglasses made of an NT alloy. In an eyeglass frame, an anti-rotation groove (12) is formed at an end of a member to be joined, and an engagement tube (13) having an inner threaded periphery is secured to the periphery of the groove (12), joined with engagement portions (8) and (9) of a rim (2), and secured to them by securing means. The bridge and bar of the eyeglass frame having the above-described arrangement are connected to each other by means of the engagement tubes. With this arrangement, it is possible to prepare a variety of parts in advance and easily replace various parts in compliance with the demands of users.

Abstract: Disclosed herein is a structure adapted to connect eye-glass parts to each other and comprising a small plate integrally extending from a main body of one eyeglass part which is made of a hardly solderable metal such as pure titanium or Ni-Ti base alloy. A connecting member made of an easily solderable metal has side walls and a cross section of U-shape defining a channel for receiving the small plate which has such constricted regions as formed at both sides surfaces of the small plate. The side walls of the connecting member are folded onto the inserted small plate such that inner surface material of said member are pressed into the constricted regions so as to be secured to said small plate. To the connecting member unseparably wound around the small plate, any other eyeglass part can be soldered or welded.

Abstract: A glasses with bridges and temples which are fixed to lens frames, without depending upon deposition. Bridges and temples of this glasses can be changed easily according to one's taste because they are not deposited to lens frames but are fixed to lens frames through the medium of sleeves and other means.

Abstract: This invention relates to spectacles in which are spectacle lens is connected to an individual component, for example a flange, by means of a fatening device. In the spectacle lens the two ends of a borehole are expanded into two borehole widenings which are engaged with a first protrusion on the flange and with a connecting element that is connected to a pin leading to the first protrusion. In addition, the flange has two further protrusions supporting themselves on the border of the spectacle lens, so that a four-point anchoring of the flange secured by the pin against pulling and by the additional protrusions against rotating is furnished on the spectacle lens and vice versa. A certain flange is suitable for given thicknesses and curvatures of the spectacle lens, because both on the front side and the back side of the spectacle lens it is not the front or back sides that define the gripping surfaces for the connecting element and first protrusion, but the borehole widening.

Abstract: Nasal equipment for spectacle frame of the type comprising in a single piece a central bar and two lateral pads each intended to interlock on the corresponding eyewire of the frame. In a central bar is provided at least one recess in which is disposed at least one interlocking element intended to cooperate with a recess provided in each eyewire of the frame.

Abstract: A spectacle frame comprising two components which constitute a supporting structure and a face assembly, respectively, mounted removably to each other, wherein one of the components comprises at least one locking element and the other component comprises a recess adapted to receive the at least one locking element being movable between a rest position wherein it allows the components to be separated from each other and an active position wherein the at least one locking element cooperates with the recess when the supporting structure and the face assembly are mounted onto each other, so as to firmly connect the supporting structure to the face assembly.

Abstract: An eyeglass frame with a detachable frame front is disclosed. The eyeglass frame comprises a main frame structure including a main cross bar and hinged temples at its ends, and the separate, detachable frame front comprises rims interconnected by a pair of parallel cross members defining a bridge. A fastener member or pad is secured to the underside of the main cross bar and has a pair of parallel grooves cooparable with the cross members for releasably securing the latter in position. One of the grooves is along the front surface of the fastener member and the other groove lies along the lower surface thereof. The fastener member also has one or more apertures cooperable with teats on an additional (sun) frame front for releasable securing the latter. Alternatively the additional frame front may be pivotally mounted on the fastener member.

Abstract: A spectacle frame comprises a crossbar and a removable lens holder comprising a central bridge, side pieces joined by the bridge retaining respective lenses. The bridge mates with a central section of the crossbar to removably attach the lens holder to the crossbar. The bridge comprises two branches curved in opposite senses, substantially in alignment with the side pieces, to constitute as plane closed loop. The branches of the bridge carry resilient retaining clips which engage co-operating edge portions of the central section of the crossbar.The central section comprises two branches curved in opposite senses and joined together to constitute a substantially plane closed loop analogous to and superposable on the closed loop formed by the curved branches of the bridge.

Abstract: The invention relates to an improvement to spectacle frames, and is more particularly directed to a novel nose plate holder which comprises a fixing tab adapted to be attached to the spectacles, an upright member adapted to support the side members of the frame and having a length at least equal to twice the thickness of said side members, a substantially U-shaped bow portion having its open end directed downwardly, and a plate attaching member adapted to support the nose plate, said fixing tab, upright member, bow portion and plate attaching member being substantially disposed in line.

Abstract: An eyeglass frame comprising two lens rings and two temples, the frame being supported and reinforced at the point of engagement of the temples and the lens rings by a loop or series of loops extending from the side of the eyeglass frame. The loop or loops that contact the outside portion of the temples is rigid enough to support and reinforce the junction of the lens ring and temple yet is pliable enough when heated to allow adjustment of the eyeglass frame to comfortably fit a wearer.
