[Industrial applications]

 The present invention relates to improvement of hinges for glasses, and more particularly to a new spring hinge capable of locking the rotation at desired two positions when a temple or the like pivotally supported by the hinges is rotated. .

[0002]

[Prior art]

 The temples of spectacles are usually hinged to the front part of the spectacles via hinges. As a result of this hinge connection, the temples are extended to the rear of the front when the glasses are used, and when the glasses are stored or carried, the temples are rotated to two positions, that is, the temples are folded along the front. , The shape of the eyeglass itself can be changed to a more desirable shape. However, the conventional hinge is designed to regulate the rotation only by the contact frictional force of the parts around the rotation axis, and does not have the ability to fix the temple even if it is rotated to the desired position. In other words, even if the temple is rotated in order to change the outer shape of the eyeglasses to the shape that suits the purpose, the temple will freely rotate in response to something and the eyeglasses will change into an unwilling shape. Of.

Further, pursuing the ideal of eyeglasses, when using eyeglasses, the temple is not only extended to the rear of the front and hooked on the ear, but also is urged inward to lightly pinch both heads. It is better to attach it. For this purpose, however, if the temple is curved inward and biased inward by the springiness of the temple itself, the central portion of the temple swells when the temple is folded. Others tried to exert an inward biasing force by incorporating a spring near the hinge connection part of the temple, but the structure tends to be complicated, so disassembling and assembling for maintenance purposes is difficult. There was a drawback that

[0004]

The present invention has been made in view of the above problems of the conventional temple hinge mechanism. Therefore, it is an object of the present invention to realize a temple hinge mechanism that can lock a temple at a desired position for rotation. This is a technical issue. Also, if necessary, the temples can be urged inward when the glasses are used, and the structure is simple and easy to disassemble and assemble, and the temples do not swell when the temples are folded. Achieving a hinged mechanism will also be a technical issue.

[Means for Solving the Problems]

 The means adopted in the present invention for solving the above problems will be described below. That is, first, two pieces are formed on the outside of the bottom of the bottomed cylindrical hinge part, and the hinge part penetrates the vicinity of the center of the bottom of the cylinder to the root part between the two pieces, while the hinge A stopper of a predetermined size and a spring are inserted into the cylindrical bore of the component, and the tip of a predetermined spectacle component to be hingedly connected is inserted and fixed in the cylindrical bore with the spring retracted. Next, another spectacle component is equipped with a single piece having two recesses of a predetermined shape on the side surface parallel to the rotation axis. Then, this one piece piece is inserted between the two piece pieces and connected by a rotary shaft to form a hinge. When desired, the front end of the stopper urged by a spring has a crotch between the two piece pieces. It is a means to lock the rotation of the hinge connection part by exposing it from the inside and fitting it into the recess of one piece. The spectacle parts to be hingedly connected in the above means specifically means, for example, temple parts or intelligent parts.

Further, if necessary, the eyeglasses component having the tip inserted into the cylindrical bore of the hinge component is fixed by a screw, so that the disassembly and assembly can be facilitated. Furthermore, if a spherical stopper is adopted, when the eyeglass component is rotated from the locked position of the stopper, the stopper is fitted naturally and is somewhat smooth.

【Example】

 The present invention will be described below based on the embodiments shown in FIGS.

A nickel alloy wire rod that is easy to cut is prepared, swaged to a predetermined diameter, and then cut into a predetermined length. From one end surface of the cut alloy wire rod, a hole is drilled to a predetermined depth in the longitudinal direction of the wire rod to form a cylinder bore 13, and the alloy wire rod is processed into a cylindrical shape with a funnel-shaped bottom inside. . Further, a slit having a predetermined width is made at the end opposite to the one where the holes are drilled to separate it into two thin plate-like projections, and the thin screw projections 11a and 11b are opened to make two holes. Form a piece 11. Next, screw holes 12 are drilled from the cylindrical surface of the alloy wire toward the cylinder bore 13 to complete the hinge part 1. In the above case, it is assumed that the bottom of the cylinder bore 13 formed first is located at the base of the tops 11 and 11 when the two tops 11 and 11 are formed. Therefore, the bottom portion of the cylinder bore 13 disappears at the central portion when the gap between the two pieces 11, 11 is formed, but a part of the peripheral edge remains at the base of the two pieces 11, 11. Further, the cylinder bore 13 penetrates to the base of the two-piece top 11.

At the rear end of the intelligent component 2, a piece 21 is formed. This one-piece piece 21 is configured by forming a hinge screw hole 21a in the center of a distorted, substantially elliptical plate having a thickness corresponding to the gap between the two pieces 11 and 11, and on the side surface thereof. Has two recesses 22, 22 cut out. Of these, one of the recesses 22 is provided at a position that is substantially straight toward the rear of the intelligent component 2 from the screw hole 21a, and the other recess 22 is toward the inside of the intelligent component 2 from the screw hole 21a. It is provided in the position. In addition, the edge of the concave portion 22 behind the one-piece frame 21 located outside the spectacles protrudes particularly long, and when the temple component 5 described later is pivotally supported, the temple component 5 is rotated outward more than necessary. It is designed to be difficult to move.

The stopper 3 and the spring 4 are inserted into the cylinder bore 13 of the hinge part 1. The stopper 3 is a stainless steel sphere, and does not fall out from the penetrating portion of the bottom of the cylindrical cavity of the hinge part 1, but only a part of the sphere is exposed from the penetrating portion to the outside of the hinge part 1. It has such a size. The spring 4 is a stainless steel coil spring. After inserting the stopper 3 and the spring 4, insert a titanium temple part 5 having a screw hole 51 near the tip, and while retracting the spring 4, the screw hole 51 of the temple part 5 and the screw hole of the hinge part. Match 12 and screw in screw 7 to fix temple part 5 to hinge part 1. In the above assembly, when the part of the stopper 3 projecting from the hinge part 1 receives a predetermined force, there is enough room for the stopper 3 to dive into the hinge part 1 while further retracting the spring 4. The lengths of the hinge part 1, the spring 4 and the insertion amount of the temple part 5 are determined so that they are left.

The intelligent component 2 is attached to the side portion of the spectacle front F so as to be brought out rearward. Further, the single piece 21 of the intelligent component 2 is sandwiched between the two pieces 11 and 11 of the hinge component 1 and is pivotally supported by the hinge screw 6 to be connected. At this time, the side surface of the one-piece piece 21 comes into contact with the stopper 3 protruding from between the two piece pieces 11 and 11 of the hinge component 1. Then, the urging force of the spring 4 locks the hinge part 1 in the direction in which the stopper 3 is most protruded. The locking direction of the hinge part 1 is aligned with the direction in which one of the recesses 22, 22 on the side surface of the one-piece comma 21 of the intelligence part 2 is located in front of the stopper 3. Therefore, the temple component 5 connected to the hinge component 1 is rotated in a predetermined direction and locked. Also, when the temple part 5 is held and rotated by hand, the hinge part 3 is naturally depressed and the hinge part 1 is rotated with respect to the intelligence part 2, and the stopper 3 is one of the intelligence parts 2. The temple component 5 is locked again when it is positioned in front of the other recess 22 of the top 21. Further, when the temple component 5 is rotated outward, the stopper 3 is fitted into the recess 22 at the rear of the piece 21. Here, when a further outward force is applied, the stopper 3 comes into contact with the outside of the edge of the concave portion 22 behind the one-piece frame 21 and opposes this force by a predetermined biasing force. Therefore, if the temple component 5 is positioned slightly inside the temporal region when the eyeglasses are worn, the temple component 5 is pushed outward by contact with the temporal region, and the spring An inward force that opposes this is generated by the hinge, and the temple part 5 and the temporal region are brought into contact with each other with a predetermined force. It should be noted that the extended portion outside the edge of the concave portion 22 behind the one-piece frame 21 comes into contact with a predetermined portion of the intelligent component 2 when the temple component 5 pivots extremely outward, and further pivots. It also has the function of preventing.

Although the present embodiment is configured as described above, the present invention is not necessarily limited to the above embodiment. For example, it is possible to improve the performance by changing the type of metal used for each part or change the color matching. In addition, one piece is formed at the tip of the temple part, and the rear end of the smart part is inserted and fixed in the cylinder bore of the hinge part having two pieces. It is also possible to equip (see Figure 4). Furthermore, when connecting the temple component and the hinge component, it is possible to use a rivet fixing method or a caulking fixing method instead of the screwing method.

[Effect of device]

 As described above, the spring hinge of the present invention can lock the rotation of the eyeglass component at two positions by combining the biasing stopper at the predetermined portion of the two-piece frame and the concave portion of the one-piece frame. If you apply this to the temple, you can lock it in two places, when the temple is opened and when it is folded. Further, when the stopper starts to shift from the center of the recess, a reverse force acts, so that it is possible to apply an inward biasing force to the temple. In addition, the whole structure is very simple, and if necessary, a screwing method is used for assembly, making it easy to replace stoppers and springs. Thus, the spring hinge of the present invention has high industrial utility value.
