Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an eyeglass frame that allows easy lens replacement and cleaning and has a good appearance.

[Prior art] Conventional eye and mirror frames generally have left and right rims connected to a central bridge, and the rims are separated at the connection point between the left and right temples and the above rims, and then connected with screws. The lens was held fixed by grooves formed within the rim.

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

However, in the above eyeglass frames, the lenses are attached to grooves formed in the rim using screws, so when used for a long period of time, the screws loosen, causing accidents such as the lenses falling out, and also making it difficult to replace the lenses. There was a problem that this could not be done easily.

For these reasons, as described in Japanese Utility Model Application No. 159150/1983, the upper part of the support frame (rim) is formed separately from other parts, and the eyeglass frame is made detachable or openable. - As described in Publication No. 72918, the bridge that connects the left and right rims is divided horizontally from the inner edge of one rim to the inner edge of the other rim, and the upper and lower pairs of the divided bridge parts are vertically separated. Replaceable lens glasses have been proposed, characterized in that the bridge castle is equipped with an attachment/detachment mechanism consisting of biasing means that can be pushed apart in the direction and means for locking the means in the fastened state position of a pair of upper and lower bridge parts. There is.

Furthermore, as described in Japanese Unexamined Patent Publication No. 59/162510, a retainer having a retaining hole formed on the back side at the tip of the rim and a shell are each provided with a spring that biases the retainer toward the retaining hole. An interchangeable lens eyeglass frame has been proposed in which fixing devices are disposed on both sides of the back of the bridge.

[Problems to be Solved by the Invention] However, in the one-lens mirror frame described in the above-mentioned Utility Model Publication No. 159150, parts of the left and right support frames (zum) are separately detachable or openable, so that the lens can be replaced. Since the work can be carried out separately on the left and right sides, the above-mentioned drawbacks have been solved, but when it is removable, screws are used to fix it, making it inconvenient to install and remove it.

In addition, if a part of the support frame is made to be openable and closable, the tip of the support frame will form a fitting part into the other support frame, but depending on the shape of the support frame, a fitting part will be formed that meshes with the other support frame. Therefore, if the locking condition fm is configured to be strong when the lens is inserted, it will take time to release the locked condition when removing the lens, and if the locking condition is configured to be loose when the lens is inserted, the lens Although it is easy to replace.

There was a problem in that the support frame that opens and closes due to impact or the like may open, causing the lens to drop.

Furthermore, it is said that it is difficult to apply the eyeglass frame described in the above-mentioned Japanese Utility Model Publication No. 51-159150 while maintaining a good appearance in the case of a metal eyeglass frame with a thin supporting frame in the lateral direction. There was a problem.

Furthermore, the eyeglass frame described in the above-mentioned Japanese Utility Model Publication No. 51-159150 has a problem in that the screws are exposed on the front side of the eyeglass frame, resulting in poor appearance.

In the lens-interchangeable glasses described in JP-A-58-72918, the left and right rims open by opening the bridge divided into upper and lower parts, and both lenses held inside can be removed. Therefore, it is necessary to perform the operation while holding both lenses, and when inserting another lens, place the lens to be replaced on one rim, then place the other lens on the other rim. Since you will be placing the lens you are trying to use, you will need to insert a second-hand lens to prevent any lenses from falling.

Must be done very carefully and keep one lens
Since the work cannot be done with F, there is a problem that the lens may fall depending on the situation.

The lens-interchangeable glasses described in Japanese Patent Application Laid-Open No. 58-72918 have a problem in that the attachment/detachment mechanism (fixing device) is located on the front side of the bridge, and the appearance is poor.

Furthermore, the above-mentioned Japanese Patent Application Laid-open No. 159150/1983.

JP-A No. 58-72918 Both eyeglass frames use regular screws for the attachment/detachment mechanism (fixing device), so if used for a long period of time, the screws will loosen and the attachment/detachment mechanism (fixing device) will be damaged, causing the rim to open. There is a problem with dropping the lens.

The interchangeable lens eyeglass frame described in JP-A No. 59-16251.0 is limited to a "fitting with a stopper hole," so advanced manufacturing techniques are required when making the fitting. Become.

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 mount, and if there is an obstruction in the fixing hole, it will be difficult to securely lock the rim, causing the rim to open. There is a problem with the lens being removed and falling, which can lead to accidents.

The present invention was developed in view of the above circumstances, and allows for the replacement of lenses on each side and the cleaning of each part. Moreover, the work is easy, and ordinary screws can be used to create the attachment/detachment mechanism (fixing device). The object of the present invention is to provide a lens-interchangeable eyeglass frame which uses a strong biasing means to prevent accidents such as lenses falling out to the maximum and has a good appearance.

[Means for solving the problem] Equipped with a temple. In an eyeglass frame having left and right rims and a bridge connecting the left and right rims, the left and right rims are separated at the left and right temple connection parts, and the separated rim tips are attached to the left and right temple connection parts. On the other hand, the left and right rim tips are each provided with a fitting that can be locked and detached by a right-angled sliding attachment/detachment mechanism (fixing device) having a spring provided in each of the left and right temples. The above left and right temples are connected by installing the left and right fittings (1) l lock, and (2) a rectangular slide type attachment/detachment mechanism (fixing device) with L dots each having a spring that allows them to be freely attached and detached. It is characterized by being lockable and detachable. Furthermore,
In accordance with the scope of the above claims, the position and shape of the attachment/detachment mechanism (fixing device) are not limited to the shape of the fixture (= shape of one fixture and right-angled slide type). If it is flexible, it can be deformed into various shapes, and the external surface of the slide part of the right-angled slide type attachment/detachment mechanism (fixing device) exposed to the outside can be deformed on the right side, and jewelry can be fixed. - It is possible to fix, transform, form and fix in a form that can be fixed, etc., and furthermore, it can be made into a design that makes it difficult to determine what the operating parts are.
When making the left and right temples, which are the main bodies of the right-angled slide type attachment/detachment mechanism (fixing device), if screws, etc. are used without using welding technology, use a (screw set screw) or an even stronger biasing means. The temple, rim, and bridge are made of titanium.

[Function] The lens interchangeable ttua frame accessory 3 according to the present invention separates the left and right rims at the temple connection part, fixes one end of the separated rims to the temple, and attaches the left and right rims to the other end. A mounting tool is provided, and an operating member and a fitting portion are provided on the left and right temples, and this allows the device to be fixedly locked and detached.

The left and right fixtures are provided with lock rod fitting openings, and a fixing device provided with a locking rod that is fitted into the lock rod fitting openings on the bridge side is disposed in each temple.

Further, the fixing device includes an operating member and a spring, and the lock rod provided on one of the operating members is biased toward the lock rod insertion opening by the spring.

The operating member is provided with a slide portion that opposes the spring and removes the lock rod from the lock rod fitting opening.

Therefore, since the lock bar is normally inserted into the lock bar insertion part in a depressed state by the spring, the fixture provided on the other rim can be firmly fixed to the temple, but the sliding part cannot be moved forward. By sliding the lock rod backward or from the back to the front depending on the structure, the lock rod is removed from the lock rod fitter 1], so that the fitting can be easily removed from the fitting part of the temple.
