Abstract: Provided is an eyeglass frame that includes a hinge with which a reduction in size and a reduction in weight can be achieved, and stable open/close operations can be performed over a prolonged period of time. The eyeglass frame includes a lens holding portion 2, a temple 3, and a hinge 5 that enables pivoting of the lens holding portion 2 and the temple a The hinge 5 includes a terminal portion 21 of the lens holding portion 2, a terminal portion 31 of the temple 3, and a coupling portion 4 that couples the two terminal portions. The terminal portion 31 of the temple 3 is selectively positioned with respect to the coupling portion 4 at a position when the temple 3 is completely open and at a position when the temple 3 is folded.

Abstract: Provided are eyeglasses with a reduced total weight achieved by a reduction in the weight of nose pads. In the eyeglasses of the present invention, a through hole is provided in each nose pad, the through hole extending in the thickness direction of the nose pad. The through hole is preferably provided in a central portion of the nose pad, and is of a size such that, when the nose pad is viewed from the front, the through hole occupies a space that is about 10 to 80%, preferably 20 to 60%, and more preferably 30 to 50% of the nose pad. The nose pads are made of a rubber-like synthetic resin.

Abstract: The eyeglasses frame includes a first hinge barrel provided on a lens holding portion, a second hinge barrel provided on a temple, a first screw that pivotably couples the first hinge barrel and the second hinge barrel, and a second screw provided in the second hinge barrel and contactable with the first hinge barrel. A tip portion of the first hinge barrel is a cam that includes a first depression where the second screw comes to rest when the eyeglasses frame is completely open, a second depression where the second screw comes to rest when the eyeglasses frame is completely closed, substantially straight portions that join the first and second depressions, and a corner portion where the substantially straight portions change direction at a point therebetween.

Abstract: The present invention provides eyeglasses (1) having left and right lenses (3) that are rimless at least in a lower half thereof wherein at least one lens-extending portion (5 to 5F) formed as a member separate from the left and right lenses (3) is attached to the eyeglasses so as to extend outward directly from each of the left and right lenses. The lens-extending portion (5 to 5F) is used for various purposes such as ornamentation, ventilation, flow control, and the like.

Abstract: Rimless eyeglasses are provided that allow a lens to be fixed to a connector only by fitting the lens into the connector, and that also enable strong engagement between the lens and the connector. Rimless eyeglasses include a rimless lens, a bridge, and a connector that is provided at the tip of a temple. The rimless lens has an inwardly extending notch near upper left and right ends thereof. The bridge and the connector have a groove having a C-shaped longitudinal cross section and extending between top and bottom surfaces thereof. The notches of the rimless lens engage with the grooves of the bridge and the connector.

Abstract: A locking claw of a first seat locking mechanism is connected to a locking claw of a second seat locking mechanism by a second wire through a relay member so that, when the first seat locking mechanism is locked by an external force such as pressing down a seat by hand, the second seat locking mechanism is locked in conjunction with the first seat locking mechanism. The locking operations for a plurality of the first and second seat locking mechanisms can be carried out collectively and easily. In addition, locking of the plurality of lock members can be carried out assuredly without being influenced by dimensional variations, variations in assembly of a first and second U-shaped fixtures and the first and second seat locking mechanisms, by stiffness of the seat or the like. Therefore, repeated closing of the seat as in the case of the prior art where either one of a plurality of lock members fails to lock can be obviated, and convenience to use of the seat can be enhanced.

Abstract: Eyeglasses having lenses, a lens frame, temples and hinges that connect the lens frame with the temples. The hinge parts are provided with elasticity or play. At the ends of the lens frame, hinge projections each having a deep hole and an elongated hole are established. At one end of each temple, a hinge thick part having two holes on the same axis is provided. A leaf spring is inserted in the deep hole, while a stem that runs through the elongated hole of the hinge projection and the two holes of the hinge thick part is provided so as to act on the leaf spring. The deep hole is the widest at its open end, and gets gradually narrower towards its deepest end. The leaf spring is preferably provided with a bendable part.

Abstract: Spectacles having a lens frame corner and an engaging arm end. The lens frame corner includes a parallelepiped block extending from the lens frame and having a top and a bottom surfaces. Each of the top and bottom surfaces of the block has a recess or a hole, a first groove having a semicircular section, and a second groove having a semicircular section at right angle with the first grooves. The arm end include a pair of parallel planar strips. The distance between the upper strip and the lower strip is such that it allows forcible insertion of the block of the frame corner. Each of the strip has a cylindrical projection facing each other which, in use, is inserted into the recess or the hole of the block and a linear projection having a semicircular section, which, in use, is inserted into one of the grooves of the block.
