Abstract: A strap lengthening arrangement for eyewear incorporating an extendable and retractable retaining strap in a hollow temple to form a part of and be attached to eyewear such as eye sight correction glasses, sunglasses, safety and protection goggles, and the like. The temple has a longitudinal passageway extending the length of the temple and an eyewear retaining strap, a moveable or traveling strap retaining block, and a block retractor are disposed within and along the length of the temple. The strap is arranged to fold back on itself first about a pivot positioned proximate the end of the temple and then again about a second pivot attached to or made part of the block effectively tripling the length of the strap within the temple. An improved block retractor and lock and release mechanism for the block are also disclosed.

Abstract: An extendable and retractable eyewear telescoping retaining strap assembly consisting of an outer tubular strap member and an inner strap member slidably disposed within the tubular member. Means are provided to secure the inner strap within the outer strap in the retracted position and to prevent the separation of the two straps when the inner strap is in the extended position. The assembly is attachable to the temple of an eyewear frame either by attaching the outer tubular strap to the temple or by attaching the inner strap to an additional retaining strap disposed within the temple. Each strap of the assembly is flexible and either longitudinally stretchable or inelastic to provide for different modes of use.

Abstract: A mechanism for extending and retracting a retainer strap for eyewear. The strap is disposed in one or both hollow temples of an eyeglass frame and is manually extended, retracted, and locked by an extension which slides in a port or passageway forming a track or slot disposed in one surface of the temple extending from the interior to the exterior of the temple. The extension provides the means to manually retract the strap from an extended position, which extended position is achieved by pulling out the strap from the rearward end, and may be used to form one component of a locking mechanism for the strap either in the extended or retracted position. The retainer straps may be either elastic, inelastic, or one of each to provide for different modes of use.

Abstract: An improved mechanism for extending and retracting a retainer strap for eyewear. The strap is disposed in a cartridge unit such as a box like container which may be inserted into the interior of one or both hollow temples of an eyeglass frame. Alternatively, the strap containing cartridge may be affixed to the exterior of the temple of any pair of eyewear of sufficient size to support the cartridge. Retainer straps suitable for use with the cartridge may be either elastic, inelastic, or one of each to provide for different modes of use.

Abstract: A temple construction arrangement for eyewear incorporating a retractable retaining strap in a hollow temple to form a part of and be attached to eyewear such as eye sight correction glasses, sunglasses, safety and protection goggles, and the like. The temple is separated or split lengthwise into two haves and a rotatable bearing, positioned transverse the length or longitudinal axis of the temple, is placed at the temple end attachable to the lens holding frame between the two halves. The retractable strap is disposed within and along the length of one side of the temple and, in combination with a longitudinal stretchable retracting member such as a spring or elastic cord, passes around the bearing. The attached retracting member is disposed along the length of the opposite side of the temple from that of the strap providing a retraction force for the retaining strap. The temple halves are then joined together to enclose the bearing, retaining strap, and retracting member as a finished unit.

Abstract: A retractable eyeware retaining strap assembly consisting of a strap and a hollow eyewear temple for containing the strap, a strap retaining block to which the strap is attached positioned within the temple and arranged to slide along the temple, an elastic member such as an extendable spring connected between the block and the eyewear end of the temple and fastening means attached to the strap at the temple end for fastening the withdrawn strap to the eyewear. A block locking device is provided to secure the block at a desired position along the temple, particularly at one end or the other. The strap is withdrawn by releasing the block at the eyewear end of the temple and retracted by releasing the block at the temple end.
