A method for production of an eyeglass temple, the method including an injection of a first material into an injection molding tool upon forming an eyeglass temple main part with a main body and an inclination bearing body, and an injection of a second material into an eyeglass temple adjustment part cavity of the injection molding tool upon overmolding at least partly the inclination bearing body to form an eyeglass temple adjustment part, which is penetrated by the inclination bearing body and pivotable in relation thereto, after the first material has cured at least partly, and a removal of the eyeglass temple, which is in an eyeglass temple injection molding position, from the injection molding tool when the first material and the second material have cured at least partly.

Eyeglasses are provided for folding into a substantially flat configuration to be fitted inside a compact case. The eyeglasses include a frame surrounding a pair of lenses, and a pair of temples which extend from respective outer edges of the frame. A first hinge connection positioned on each temple allows outer parts of the pair of temples to be folded horizontally inwards from the unfolded configuration into a first folded configuration. Respective inner parts of the temples are rotatable downwards relative to opposite side edges of the frame about respective second hinge connections into a fully folded condition substantially coplanar with the frame. In some embodiments, the frame and tips or earpieces of the temples are of rigid plastic material while the temples and hinge connections are of metal.

A frame comprises a front portion, connecting members, a first arm coupled to a first connecting member by a hinge, and a second arm coupled to a second connecting member by a hinge. The first and second connecting members are coupled to the front portion by hinges. The first arm is rotatable, relative to the first connecting member, about a first pivot axis, and the second arm is rotatable, relative to the second connecting member, about a second pivot axis. The first pivot axis and second pivot axis are parallel to each other and positioned at an angle relative to lengths of the first and second arms, respectively. The first and second connecting members are rotatable, relative to the front portion, about a third pivot axis, which is positioned at an angle relative to the first pivot axis and the second pivot axis.

A joint for coupling a side arm to a frame of a pair of glasses. The joint includes a post, a plurality of prongs, and optionally a nut. The post is configured to be secured to one of the side arm or the frame and the plurality of prongs are configured to be secured to the other of the side arm or the frame. The post includes a shaft and an enlarged head at a distal end of the shaft. The plurality of prongs define a socket configured to receive at least a portion of the enlarged head of the post and apply a compressive force against the enlarged head of the post. The nut may be configured to generate a compressive force against the plurality of prongs. The compressive force may be adjusted by threading the nut along the length of the prongs. The nut may threadably engage a base that the prongs extend from and/or the prongs.

Rotary eyeglasses comprise a fixed frame bearing a nose abutment and means for holding the eyeglasses on the head, and a movable frame comprising optical members in front of the eyes, when the eyeglasses are in an operational position, wherein the movable frame is secured to the fixed frame by a multi-lever mechanism and is configured to be lifted up relative to the fixed frame and simultaneously to be rotated about its longitudinal axis owing to hinges located in points of securing the levers to the frames. The invention may be used in eyeglasses having positive lenses including reading eyeglasses, and also in protective eyeglasses of different types including sunglasses. The invention allows lifting lenses over the user's forehead, and thus facilitates looking either through lenses or beside lenses, and allows preventing contact between the inner surface of the lenses and the forehead, and thus avoiding contamination of the lenses.

A hinge for a spectacles frame, comprising a front-face element, a side element and a connecting element connecting said front-face element to said side element, said connecting element comprising a base member, mounted in the side element, and a head member, housed in the front-face element, the base member being articulated directly to said head member about a vertical first axis of articulation, the head member of the connecting element being articulated directly to the front-face element about a horizontal second axis of articulation.

The disclosure herein describes an apparatus for dual-frame eyeglasses that include a foundation eyeglass frame that may be worn on the user's head, and a pivot eyeglass frame that is rigidly coupled to the foundation eyeglass frame via a pair of pivot mechanisms. The pivot eyeglass frame may be substantially similar in form and profile to the foundation eyeglass frame. The pivot eyeglass frame may be configured to incrementally rotate about the pivot mechanism from a first position that substantially overlaps a user's line of sight through to a second position that is angularly offset away from the user's line of sight. Additionally, the foundation eyeglass frame may include a nose bridge that separates into two elements at a coupling point on the nose bridge to facilitate each half of the foundation eyeglass frame folding into a separate, compact form.

A hinge assembly comprising a guide body, a first connection element, a second connection element, a first spring and a second spring; the guide body comprising a first end surface and a second end surface provided at opposite sides respectively, wherein the first end surface is provided with a first guide slot, the second end surface is provided with a second guide slot, and the first guide slot and the second guide slot intersect orthogonally, the first connection element is provided with first connection end extending beyond an end surface of the endpiece, the second connection element is provided with a second connection end extending beyond an end surface of the temple end, the first connection end and the second connection end are hingedly connected and pivoted with each other within the guide body; A glasses frame comprising an endpiece, a temple, and a hinge assembly.

A slip-resistant eyewear system comprising an eyewear frame generally comprises a nosepiece comprising a nosepiece material configured to couple to a bridge of an eyewear frame. The frame comprises first and second hinges coupled to the eyewear frame which are also coupled to first and second spring-loaded tension adjusters. First and second bows are coupled to first and second tension adjusters. A first bow extension element is coupled to the first bow and comprises a first fastening element at a first end of the first bow extension element and a second bow extension element is coupled to the second bow and comprises a second fastening element at a first end of the second bow extension element that is configured to mate with the first fastening element to secure the first and second bow extension elements together.

Embodiments of the present application provide a rotating shaft mechanism, a connection mechanism for glasses, and glasses. The rotating shaft mechanism includes: a first component having a first abutting portion; and a second component having a second abutting portion, the second component being rotatably connected to the first component, and the second component being rotatable relative to the first component and having a first position and a second position. The first component includes a cooperating portion, and when the second component is in the first position, the first abutting portion interacts with the second abutting portion to maintain the second component in the first position, and when the second component is in the second position, the cooperating portion interacts with the second abutting portion to maintain the second component in the second position; or the second component includes a cooperating portion, and when the second component is in the first position, the first abutting portion interacts with the second abutting portion to maintain the second component in the first position, and when the second component is in the second position, the first abutting portion interacts with the cooperating portion to maintain the second component in the second position.
