Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spectacle frame, and more particularly to a spectacle frame configured so that appropriate parts thereof can be folded and folded to form a flat-plate thin body as a whole.

[0002]

[Prior Art]

 At present, the structure of the spectacle frame that is generally used is such that the spectacle temple pivotally connected to the front frame is simply rotated within a range of about 90 degrees with respect to the front frame to be folded or unfolded. In many cases, the eyeglass temples can be pushed outward by the elastic deformation of the eyeglass temples so that the temples on both sides can be easily inserted between the eyeglass temples. However, if the eyeglass temples are slightly pushed apart when putting on or taking off the eyeglasses, the joints between the front frame and the eyeglass temples eventually loosen, or even the eyeglasses as a whole It easily causes frame deformation. On the other hand, even if it is taken by the user, it is unavoidable that the temple bite is strongly pinched for a long period of time, and in addition, ordinary eyeglasses simply fold the eyeglass temple sideways on the back side of the front frame. Since it is designed to fit and the eye rests are formed at each end of the spectacle temple, there is a considerable thickness in the retracted state when the spectacle temple is folded to the back side of the front frame. There are times when it is quite inconvenient to carry and carry an eyeglass, and it is hard to say that such a design is satisfactory for those who have to carry glasses with them at all times.

[0003]

[Problems to be solved by the device]

 In view of the above-mentioned problems of the conventional spectacle frame, the present invention provides a pair of spectacles and a pair of spectacles front frames with connecting bodies at the bases of both ends of the pair so that the spectacles vines are substantially flush with the front frame. In addition to the above, it is an object of the present invention to provide an ophthalmoscope frame that can reduce the thickness of the retracted state on the second plane orthogonal to this, and can push it outward from both ends of the front frame. And

[0004]

[Means for Solving the Problems]

 Therefore, the present invention provides a spectacle frame in which spectacle temples are pivotally connected to both ends of the front frame via hinges so that they can be folded in the space between both ends of the back side of the front frame. The object is achieved by a structure in which universal joints are attached to both ends, and the spectacle temple is foldable so as to rotate in the direction of the secondary dimension with respect to the front frame so as to be flush with the front frame.

Then, the universal joint is a ball joint, and the positioning means makes it approximately 90 degrees on the first surface substantially along the front frame and on the second surface orthogonal to the first surface. To allow rotation within a limited angular range, and as the positioning means, a seat for receiving the ball of the ball joint so that the spectacle temple can rotate only along the second surface. A two-pronged yoke is defined, and the tip of the spectacle temple is connected to the ball through a pin and urged by a coiled spring. If it is slidably pressed against the end of the yoke and separated from it against the spring, it is possible to rotate within a range limited to about 90 degrees, or a columnar body connected to the ball joint. Make a slot on the bottom end face and move it into the slot. Install a possible nut and spring, connect the ball joint, provide a storage chamber inside the end face, and attach a connecting body with a bolt that penetrates the upper wall surface of the opening of the storage chamber end face. Further, it is more preferable to insert the tip of the column into the storage chamber of the connecting body and screw the bolt into the nut to integrally connect the ball joint and the connecting body.

[0006]

[Action]

 Since the spectacle frame of the present invention is constructed as described above, the pair of spectacle temples is pivotally connected to one end of each of the pair of universal joints attached to both ends of the spectacle front frame, and the pair of spectacle temples is attached to the rear side of the spectacle front frame. It can be folded facing each other in the space between both ends, and it can be pushed outward from both ends of the front frame, and further rotated to the upper end face or the lower end face of both ends of the front frame. It can also be flush with the frame.

Then, the universal joint is a ball joint, and by the positioning means, it is approximately 90 degrees on the first surface substantially along the front frame and on the second surface orthogonal to the first surface. To allow rotation within a limited angular range, and as the positioning means, a seat for receiving the ball of the ball joint so that the spectacle temple can rotate only along the second surface. A two-pronged yoke is defined, and the tip of the spectacle temple is connected to the ball through a pin and urged by a coiled spring. If it is slidably pressed against the end of the yoke and separated from it against the spring, it is possible to rotate within a range limited to about 90 degrees, or a columnar body connected to the ball joint. Make a slot on the bottom end face and move it into the slot. Install a possible nut and spring, connect the ball joint, provide a storage chamber inside the end face, and attach a connecting body with a bolt that penetrates the upper wall surface of the opening of the storage chamber end face. Further, if the tip of the pillar is inserted into the storage chamber of the connecting body and the bolt is screwed into the nut to integrally connect the ball joint and the connecting body, the eyeglass temple The operation of pressing and expanding or folding and folding the entire spectacle frame in the same plane can be performed more smoothly.

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

[Effect of the device]

 In the spectacle frame of the present invention configured as described above, the pair of spectacle temples is pivotally connected to one end of each of the pair of universal joints attached to both ends of the spectacle front frame, and It can be folded facing each other in the space, and it can be pushed outward from both ends of the front frame, and can be rotated to both upper and lower end faces of both ends of the front frame to be flush with the front frame. Since it is also possible to put on the glasses easily, the wearing condition is also comfortable, and it is convenient to carry by folding the whole in the same plane and thin.

On the other hand, the universal joint is a ball joint, and by the positioning means, it is limited to about 90 degrees on the first surface substantially along the front frame and on the second surface orthogonal to the first surface, respectively. Of the ball joint of the ball joint so that the eyeglass temple can rotate only along the second surface. In addition to a bifurcated yoke, the tip of the spectacle temple is connected to the ball through a pin and urged by a coiled spring, and when the spectacle temple is axially moved, the pins are slidably pressed against one end of a limited distance. Contacting the end of the yoke and separating it against the spring makes it possible to rotate within a range limited to about 90 degrees, or a groove hole is formed in the bottom end face of the column connected to the ball joint. A nut that can be moved into the slot. Is attached to the ball joint, a storage chamber is provided inside the end face of the ball joint, and a connecting body equipped with bolts for inserting the upper wall surface of the storage chamber end face opening is attached. If the ball joint and the connecting body are integrally connected by inserting the bolt into the storage chamber of the connecting body and screwing the bolt into the nut, the eyeglass temples can be expanded or the entire eyeglass frame can be brought into the same plane. The folding operation can be performed more smoothly.
