Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a spectacle frame having a good appearance that allows easy replacement and cleaning of lenses.

[Prior Art] In the conventional eyeglass frame, the left and right rims are generally formed integrally with the central bridge, and the rims are separated at the connection points between the left and right temples and the above rims, and the rims are joined by screws to fit inside the rim. The lens is fixedly held by the formed groove.

When replacing the lens, the lens is replaced by removing the screw.

However, in the above-mentioned spectacle frame, the lens was attached to the groove formed in the rim by screwing, so if the lens is used for a long period of time, not only will the screw loosen and the lens will fall out, but lens replacement is easy. There was a problem that it could not be done.

Under these circumstances, an eyeglass frame in which the upper portion of the support frame (rim) is formed separately from other portions as described in Japanese Utility Model Application Laid-Open No. 51-159150, and is detachable or openable / closable. As described in JP-A-58-72918, a bridge connecting left and right rims is horizontally divided from the inner edge of one rim to the inner edge of the other rim, and the bridge between the pair of upper and lower bridge portions is divided. A lens-replacement type eyeglasses characterized by comprising an attaching / detaching mechanism on the bridge, which comprises an urging means capable of pushing and expanding in the vertical separation direction and a means for locking the means at a fastening state position of a pair of upper and lower bridge parts. Has been done.

Further, as described in Japanese Patent Laid-Open No. 59-162510, a fixing is provided with a mounting member having a rear side with a stop hole at the rim tip and a spring for urging the stop bar toward the stop hole. An interchangeable lens type eyeglass frame has been proposed which is characterized in that the devices are arranged on both sides of the back surface of the bridge.

[Problems to be Solved by the Invention] However, in the spectacle frame described in Japanese Utility Model Laid-Open No. 51-159150, parts of the left and right support frames (rims) are separately attachable / detachable or openable / closable to remove the lens. Since the replacement work can be performed separately on the right and left sides, the above-mentioned drawbacks have been solved, but when it is detachable, a screw is used to fix it, which makes attachment and detachment inconvenient.

Further, when a part of the support frame is openable and closable, a tip portion of the support frame is to be fitted into the other support frame, but a fitting portion that meshes with the shape of the support frame is formed. Therefore, if it is configured so that the locked state is strong when it is fitted, it takes time to unlock the lens when removing the lens, and if the locked state when fitted is loose, lens replacement Is easy, but
There is a problem in that the support frame that opens and closes due to impact or the like opens, and the lens may drop.

Further, the spectacle frame described in Japanese Utility Model Application Laid-Open No. 51-159150 is difficult to apply in a state of good appearance in the case of a metallic spectacle frame in which the lateral thickness of the support frame is thin. There was a problem.

Furthermore, the spectacle frame described in Japanese Utility Model Publication No. 51-159150 is
Another problem is that the screws are exposed on the front side of the spectacle frame and the appearance is poor.

In the lens interchangeable glasses described in JP-A-58-72918, the left and right rims are opened by opening the vertically divided bridge up and down, and both the lenses held inside are removed. Therefore, it is necessary to operate while holding both lenses, and when inserting another lens, place the lens to be replaced on one rim and then replace the other side on the other rim. Since the lens to be tried is placed, it is necessary to insert the other lens so as not to drop the lens on one side, it is necessary to perform it very carefully, not holding one lens and doing the work Therefore, there is a problem that the lens may be dropped in some cases.

In the interchangeable lens type glasses described in JP-A-58-72918, the attaching / detaching mechanism (fixing device) is located on the front side of the bridge.
There is also a problem that the appearance is bad.

Furthermore, the eyeglass frames of both JP-A-51-159150 and JP-A-58-72918 use ordinary screws for the attachment / detachment mechanism (fixing device), so the screws will loosen after long-term use. There is a problem that the attachment / detachment mechanism (fixing device) is damaged, the rim opens and the lens is dropped.

Since the interchangeable lens type eyeglass frame described in Japanese Patent Laid-Open No. 59-162510 is limited to "a fixture having a stop hole", a high-level manufacturing technique is required when manufacturing the fixture.

Furthermore, when cleaning, it is easy to clean between the lens and the rim, but it is not easy to clean the fixing hole of the fixture.
If there is an obstacle in the stop hole, there is a problem that it becomes difficult to firmly lock and the rim opens and the lens falls out.

The present invention has been made in view of such circumstances, and it is possible to replace the lens on each side and clean each part, and the work is easy, and a normal screw is used for manufacturing the attachment / detachment mechanism (fixing device). It is an object of the present invention to provide a lens-interchangeable eyeglass frame having a good appearance by using a strong urging means without preventing the lens from falling out to the maximum extent.

[Means for Solving the Problems] In the present invention, in an eyeglass frame having left and right rims provided with temples and a bridge connecting the left and right rims, the left and right rims are respectively separated at connection portions with the bridge, One of the separated ends of the rim is fixed to the left and right connecting parts of the bridge respectively, and a mounting tool is provided on the other of the separated ends of each rim, and a slide type attachment / detachment mechanism is attached to the left and right connecting parts of the bridge.
