说明书全文 | This application requests foreign priority from and incorporates by reference attached certified copy China application 200410086772.8 filed Nov. 1, 2004. This invention relates to one kind of eyeglass; it particularly relates to one kind of Eyeglasses that can be folded to form a case. In the case of the common eyeglasses, the temple bars are folded inward and then the eyeglasses are put into an eyeglass case to be carried away. That kind of operation is very inconvenient, particularly for elderly folks who use bi-focal eyeglasses and need to put on and take off the bi-focal eyeglasses frequently. This invention overcomes the shortcomings of the current technology by providing Eyeglasses that can be folded to form a case which is easy to use. To achieve the above-mentioned goal, this invention provides one kind of Eyeglasses that can be folded to form a case that is comprised of lenses and temple bars; a lens and a temple bar are two separate objects of connection; the two are joined together through a hinging apparatus. One end of the hinging apparatus forms a rotating connection with one object of connection; the other end of the hinging apparatus forms a pivotal connection with another object of connection. The rotating connection and the pivotal connection are perpendicular to each other. Two hollow sections are formed on those two temple bars. By turning and locking the hinging apparatus, the lenses can be stored in the chamber formed by the two hollow sections. The hinging apparatus is a hinging apparatus with a locking position at a set angle. When not in use, this invention, which is one kind of Eyeglasses that can be folded to form a case, can be conveniently folded into a case with the lenses stored inside the temple bars. That is why this invention is very convenient, particularly for elderly folks who use bi-focal eyeglasses. The hinging apparatus with a pre-set locking position makes the rotation of the temple bars more precise and makes the closing-up of the temple bars with more ease. Implementation 1 This invention of one kind of Eyeglasses that can be folded to form a case is comprised of lenses (1) and temple bars (2); a lens (1) and a temple bard (2) are connected to a hinging apparatus (3). The hinging apparatus (3) is comprised of a rotating connection section and a pivotal connection section, as shown in Illustration 3; the rotating connection section includes the anchoring body (31). The anchoring body (31) can be a in the shape of a cube; it is affixed to the outer side of the lens (1); on the anchoring body (31), on the side opposite to the lens, is a hole into which the connecting shaft (35) is inserted. Near the tip of the connecting shaft (35) that sticks into the anchoring body is a recessed neck (37). On the adjacent side is a threaded hole (36) that is at a right angle to the insertion hole. In the threaded hole (36) are installed, in sequence, a depresser (32), a spring (33), and a screw (34). The depresser (32) can be in the shape of a round disk, one end of which presses against the side of the recessed neck (37); the spring (33) pushes again the other end of the depresser (32). The screw (34) is twisted into the threaded hole (36) and depresses the spring (33), which, in turn, pushes the depresser (32) against the surface of the recessed neck (37); as a result, a rotating connection is formed between the connecting shaft (35) and the anchoring body (31), i.e., the connecting shaft (35) can rotate with the recessed neck (37) as the axis. The other end of the connecting shaft (35) is connected to the front end of the temple bar (2) and forms a pivotal connection. The rotating axis and the pivotal axis are perpendicular to each other, i.e., the axis line of the rotating axis and the axis line of the connecting shaft (35) share the same axis; the axis line of the pivotal axis and the axis line of the connecting shaft (35) are perpendicular to each other. The structure of the pivotal connection can be of a regular structure, for example, the pivotal connection end of the connecting shaft (35) is made into a flat tooth (38); on the tooth (38) is a hole; the tooth (38) in inserted into the temple bar; a screw is inserted from one side of the temple bar (2) and, after going through the hole on the tooth (38), is screwed onto the other side of the temple bar (2). As a result, the temple bar (2) forms a pivotal connection with the connecting shaft (35) by using the screw as the pivot. On the inner side of each of the two temple bars (2) is a hollow section (21) with an opening that faces the inner side. When the hollow sections (21) on the temple bars are closed together a case with an empty chamber is formed, within which the lenses (1) can be stored. The hollow section (21) can also be adjacent hollow sections with two openings, i.e., the openings can be on the upper and inner sides of the temple bars (2), so long as the locations of the hollow sections are identical on the two temple bars. For easy wearing of the eyeglasses, it would be preferable to taper off the temple bars (2) starting from the point where they are connected to the lenses (1); the ends of the temple bars can rest on the ears of the wearer. The shape of the temple bars can take on other shapes, as shown in When eyeglasses with the preceding configuration are worn, the eyeglasses are in the state shown in The recessed neck (37) can be in the shape of a polygonal post, as shown in Implementation 2 All other conditions are the same as those in Implementation 1, except that the structure of the hinging apparatus (3) between the temple bars (2) and the lenses (1) can be modified. The manner of connection of the hinging apparatus (3) between the connecting shaft (35) and the temple bar (2) can remain unchanged; except that the rotating connection section between the connecting shaft (35) and the lens (1) can be as shown in One end of the rotating connection section between the connecting shaft (35) and the lens (1) is the groove section (41); the other end is the ridge section (42); the two are connected by a spring (43). At the tip of the groove section (41) are a number of semi-spherical surfaced or spherical crown surfaced grooves (412) that are evenly distributed along the circumference, i.e., the surface of a groove is smaller than one half of a sphere. A round tubular shank (411) sticks out from the center of the surface of the groove section (41); the round tubular shank (411) should be concentric with the circumference on which a number of grooves (412) are scattered; on the surface of the ridge section (42) is a notch (421) that couples up with the groove (412), i.e., the size and shape of the notch are identical to those of the groove. In the ridge section (42) there are is round tubular hole (422) at a location that corresponds to the shank (411); the shank (411) can be inserted into the round tubular hole (422); together, the two allow a sliding movement. When the shank (411) is inserted into the round tubular hole (422), the notch (421) sets into the groove (412). The groove section (41) and the ridge section (42) match up and form the rotation plane; the spring (43) and the rotation plane are aligned concentrically; the spring (43) can be set inside the groove section (41); one end of the spring (43) pushes against the internal surface (413) that corresponds to the surface of the groove (412); the free end of the spring (43) connects to the inside of the ridge section (42) through a pull rod that passes through the shank (411) and the round tubular hole (422), as a result, the ridge section (42) is connected to the groove section (41) through the spring (43). The pull rod that is mentioned herein, as shown in As a result, the groove section (41) and the ridge section (42) can turn with the shank (411) as the axis; the convex ridge (421) glides from one groove (412) to another groove under the elastic effect of the spring (43), which, in turn, allows rotation between the connecting shaft (35) and the lens (1). Because the grooves (412) are not continuous, they produce locking position(s) at certain set angle(s) as the rotation is in progress. If the groves (412) are one continuous circular groove, a continuous rotation is produced. The groove (412) and the ridge (421) can be semi-oval shaped; such structure can also produce the same result. It would be best to place arc shaped guiding grooves (414) on the circumference where the multiple grooves (412) are scattered so that the rotation between the ridge section (42) and the groove section (41) is more accurate. Implementation 3 All other conditions are the same as those in Implementation 2, except that there can be multiple ridges (421) so long as their locations and sizes correspond to the multiple grooves (412). Implementation 4 All other conditions are the same as those in Implementation 2 or Implementation 3, except that the pull rod on the spring can be a thick “I” shaped rod (432); as shown in Here, the shank (411) can be eliminated. In the middle of the groove section (41) is a round hole that is identical to the round tubular hole (422); the thick rod (432) passes through the round hole and the round tubular hole (422) and forms a sliding union with the two holes. Implementation 5 All other conditions are the same as those in Implementation 2 or Implementation 3, except that the spring (43) can be placed inside the ridge section (42). Through the same method that is mentioned above, the ridge section (42) and the groove section (41) are connected. Implementation 6 All other conditions are the same as those in Implementation 1, except that the structure of the hinging apparatus (3) between the temple bar (2) and the lens (1) can be modified. The manner of connection between the temple bar (2) and the connecting shaft (35) of the hinging apparatus (3) can remain unchanged, except that the rotating connection section of the connecting shaft (35) and the lens (1) can be as shown in At one end of the rotation connection section, which is between the connecting shaft (35) and the lens (1), is a ridge section (44); the other end is a groove section (45); at the end of the ridge section (44) is positioned a raised round tube (441); on either side of the round tube (441) are two rectangular holes (442); within the round tube (441) is placed a circular spring piece (443); the circular spring piece (443) is an elastic ring with an opening; the two open ends of the circular spring piece (443) are inserted into the round tube (441); through the rectangular hole (442), the two sides the left and right sides of the circular spring piece (443) stick out of the round tube (441) thereby allowing the circular spring piece (443) to expand and contract in the direction of the diameter of the round tube (441). At one end of the groove section (45) is a recessed tubular groove (451); the round tube (441) of the ridge section (44) can stick into the tubular groove (451); the circular spring piece (443) locks in the tubular groove (451); as a result, the circular spring piece is pressed inside the tubular groove (451) thereby allowing the groove section (45) and the ridge section (44) to turn. The ends of the groove section (45) and the ridge section (44) are connected with bolts or rivets that can turn thereby allowing the groove section (45) and the ridge section (44) to turn but not to be pulled upward in the direction of the axis and be separated. Implementation 7 All other conditions are the same as those in Implementation 6, except that the tubular groove (451) in the groove section (45) can be in the shape of a round tube or a polygonal tube, such as in cubical shape, the cross-section view of which is shown in Implementation 8 All other conditions are the same as those in Implementation, i.e., the structure of the rotating connection section is the same as that in Implementation 1, except that, as shown in The other end of the connecting shaft (35) forms a pivotal connection with a connector (51) which is connected to the outer side of the lens (1), i.e., there is a groove at the other end of the connecting shaft (35); in the middle, perpendicular to the groove is a threaded hole; the connecting shaft (35) and the protruded end of the connector (51) are connected together with a screw, thus forming a pivotal connection with the screw as the axis; the rotating axis and the pivot are perpendicular to each other; other usual structure can be adopted as the structure of the pivotal connection. Implementation 9 All other conditions are the same as those in the above Implementation, except that the lens (1) is affixed by the lens frame, the hinging apparatus (3) forms a hinge with the lens (1) through the lens frame. |
