摘要 | Glasses of the kind to be worn for reading and including a pair of optical lenses to be positioned over the eyes of a wearer, first and second frame ends surrounding respective ones of the lenses, and a flexible bridge extending between the first and second frame ends. According to a preferred embodiment, the flexible bridge enables the first and second frame ends to be rotated toward one another, whereby the optical lenses will be aligned one above the other to create a space-efficient folded glasses configuration suitable for storage and transport in a compact enclosure. By way of example, the flexible bridge extending between the opposing frame ends is one of a wire having a spring memory, a coil spring, or a hinge. A handle is attached to one of the frame ends to receive a pushing or a pulling force to enable the wearer to slide his glasses, in their folded configuration, into the compact enclosure or to remove the glasses from the enclosure at which time the glasses will automatically return (i.e., expand) to their normal unfolded configuration ready for use. | ||||||

说明书全文 | 1. Field of the Invention Folding glasses are disclosed of the type to be used from time-to-time for reading. A flexible bridge extends between a pair of optical lenses to permit the glasses to be manipulated to a space-efficient folded configuration at which to be removably received for storage and transport within a compact enclosure. 2. Background Art Depending upon his circumstances, a wearer may need to have available a pair of glasses to be worn from time-to-time for reading when his existing eyesight or a primary pair of distance glasses is ineffective. That is to say, the wearer will be required to carry with him or have ready access to a pair of reading glasses that will only be worn on a short-time basis. Sometimes, because of its size, there is no place on the wearer's person at which to easily carry a pair of reading glasses. Other times, the wearer may simply forget to carry his reading glasses. Consequently, the wearer will be deprived of the benefit of having with him on a regular basis a pair of glasses to be worn on those occasions when small print must be read. Therefore, what is desirable is a pair of (e.g., reading) glasses that can be folded in a space-efficient configuration for receipt within a compact enclosure that is suitable to be conveniently and non-obtrusively carried on a regular basis in the wearer's shirt pocket, pants pocket, purse, key chain, and the like. Folding glasses are disclosed having particular application for reading. The folding glasses include a pair of optical lenses, a first frame end surrounding at least some of a first of the pair of lenses, and a second frame end surrounding at least some of the other lens. A flexible bridge extends between the first and second frame ends. By virtue of the flexible bridge, the frame ends can be manipulated from an unfolded configuration, at which the pair of lenses are axially-aligned with one another to cover the eyes of a wearer, to a folded configuration, at which the first and second frame ends are rotated towards one another so that the pair of lenses are positioned one above the other. By way of example only, the flexible bridge extending between the first and second frame ends has a spring memory. In this case, the flexible bridge may be one of a wire manufactured from spring steel or a coil spring that is bent (i.e., stressed) when the frame ends are rotated to the folded configuration. By way of an additional example, the flexible bridge includes a hinge around which the frame ends are rotated to the folded configuration. With the first and second frame ends rotated to the folded configuration, the glasses will be sized to fit and be transported within a compact enclosure. The enclosure allows the folded glasses to be conveniently and non-obtrusively carried on a regular basis in the wearer's shirt pocket, pants pocket, purse, and the like. A ring attached to the enclosure facilitates coupling the enclosure to a key chain or a key ring. In this manner, the glasses will be carried along with the wearer's keys so as not to be easily forgotten and left behind. Folding glasses 1 according to a preferred embodiment of this invention are initially described while referring to As is best shown in However, unlike conventional glasses, the folding glasses 1 are devoid of the usual arms that are pivotally coupled to the frame ends 7 and 9 to rest upon respective ones of the wearer's ears. By avoiding the arms, and as will soon be explained, the folding glasses 1 may be more easily stored and transported in a space efficient folded configuration within a compact enclosure (designated 20 in In accordance with an important feature of this invention, the opposing frame ends 7 and 9 are capable of being folded towards one another to establish the aforementioned space-efficient configuration suitable for storage and transport within the enclosure 20 when use of the lenses 3 and 5 is not required. The foregoing folding capability is achieved by the bridge 10 between frame ends 7 and 9 having a flexible characteristic. By way of a first example, and continuing to refer to By virtue of its flexible nature, the wire bridge 10 will be stressed and bent by the wearer when the opposing frame ends 7 and 9 are rotated downwardly and towards one another (in the direction of the reference arrows of The enclosure 20 is preferably manufactured from a material (e.g., vinyl or cloth) that will not scratch the lenses 3 and 5 carried therewithin. The enclosure 20 has an open end 22 within which to receive the glasses 1 in the folded configuration in response to a pushing force applied thereto. In this same regard, whenever they are needed, the glasses 1 can be removed from the open end 22 of enclosure 20 in response to a pulling force applied to handle 12 (represented by the reference arrow in Ideally, the enclosure 20 is a small case or pouch having a flexible characteristic so as to be adapted to expand around and prevent the glasses 1 in the folded configuration from accidentally sliding outwardly through the open end 22. In the alternative, the enclosure 20 may have an inflexible, rigid construction to retain the folded glasses 1 therein by means of friction. By way of example, and as is best shown in A ring 24 is carried by an end of the enclosure 20 that lies opposite the open end 22. The ring 24 is attached to enclosure 20 at a hole 26 formed therethrough. The ring 24 provides the wearer with the advantage of being able to carry small articles (e.g., a key) alongside the enclosure 20. In addition, the ring 24 enables the enclosure 20 to be coupled to a key chain or a key ring. In this manner, the wearer will advantageously be able to carry a pair of reading glasses along with his house keys or car keys such that the glasses will not be easily forgotten and left behind.
