Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is mainly used for sunglasses, fashion eyeglasses, sports eyeglasses, dustproof eyeglasses, and the like, which is a temple of eyeglasses whose temples can be easily attached and detached. The present invention relates to a connection device.

[Conventional technology]

BACKGROUND OF THE INVENTION Conventionally, commonly used eyeglasses have a hinge in which a hinge for connecting a temple provided at both ends of a lens frame fitted with a lens and a connecting end of the temple are rotatably attached with a pin as a fulcrum. The hinge type is the mainstream.

However, in this case, the hinge part and the connecting end part of the temple are connected with a pin by a fine screw, and a special screwdriver is required for screwing the screw pin,
The connection is difficult for an unskilled person, the work is difficult for an amateur, and there is a problem that the connection work requires labor and cost, and further, the screw pin may be loosened during use.

On the other hand, in recent years, there has been a tendency to use eyeglasses as a fashionable accessory, and there is an increasing demand for fashion eyeglasses and sunglasses having a particular color and shape for the frame and the temple.

Therefore, there is a demand for eyeglasses that can be easily attached to and detached from each other so that they can be combined in various ways according to the taste of each person. It is said that it would be very convenient if the spare vine could be immediately replaced when it was broken.

[Problems to be solved by the invention]

SUMMARY OF THE INVENTION The present invention has been made in order to meet the above-mentioned demands, and it is an object of the present invention to provide a temple connecting device for eyeglasses in which a temple can be easily attached to or detached from a lens frame at its connecting portion. It is what

[Means for Solving the Problems]

As a means for solving the above-mentioned problems, the temple connecting device for eyeglasses of the present invention is a hinge male portion for temple connection protruding on the outside of the eyeglass frame of the eyeglass, sandwiched between female hinge portions of the temple, The upper and lower surfaces of the male hinge portion and the upper and lower inner surfaces of the female hinge portion are fitted with concave and convex portions provided respectively, and a closed slide member that can be press-fitted or withdrawn is provided on the temple side. When attaching and detaching the male hinge portion and the female hinge portion, the convex portion is projected to such an extent that it rubs against the surface having the concave portion,
By press-fitting or withdrawing the annular slide member, it is possible to easily and quickly attach or remove the temple to or from the lens frame.

The annular slide member may be a rigid material or an elastic material, and its width and shape can be appropriately selected from wide width, ridge width, cylindrical shape, polygonal cylindrical shape, and the like. A transparent or colored one, a decorated one, or the like can be appropriately selected according to its use.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 2 is a plan view of a main part of eyeglasses according to the first embodiment of the present invention,
FIG. 3 is a side view of the main part of the spectacles of FIG. 1, and FIG. 3 is an enlarged perspective view of the annular slide member of FIG.

First, on the outer circumference of the hinge female part 5 of the temple 4 that is held from the upper and lower surfaces of the hinge male part 3 for connecting the temples at both ends of the lens frame 2 in which the lens 1 of FIGS. 1 and 2 is fitted, As shown by the solid line in FIG. 1, there is provided a closed slide member 6 of, for example, a quadrangular cylinder made of nylon shown in FIG.

Further, the upper and lower surfaces of the hinge male portion 3 of the ball frame 2 and the hinge female portion 5 of the vine 4 which sandwiches those surfaces from above and below are used as the hinge fulcrum of the hinge male portion 3 and the vine 4 as the ball frame 2. In order to have a function of making it rotatable with respect to each other, there is provided a concave-convex portion 7 which is fitted correspondingly.

Then, when the male hinge 3 and the female hinge 5 are attached and detached, the convex portions are projected so as to rub against the surfaces having the concave portions.

Next, FIG. 4 and FIG. 5 show a temple connecting device for eyeglasses according to a second embodiment having a function similar to that of the first embodiment, and in this case, a ring shape having a ridge width as shown in FIG. The annular slide member 6 is press-fitted or withdrawn in the direction of arrow A or B.
, The same parts are indicated by the same part numbers.

[Effect of device]

According to the eyeglasses temple connecting device of the present invention described above,
Since the closed slide member 6 is fitted to the temple 4 as tightly as possible within the range where it can be slid, by sliding this onto the hinge female portion 5, the hinge female portion 5 is pressed tightly inward, Connection hinge part male 3 and hinge female part 5
Can be reliably integrated, and the vine can be smoothly rotated without obstructing the rotation of the vine, and the vine can firmly connect the lens frames.

Further, since no processing such as a break is added to the inside of the lens frame 2, the lens frame 4 is loosened and the lens 1 is detached from the lens frame 4 when the lens frame 2 and the temple 4 of the glasses are attached or detached. There is no such thing. That is, in the eyeglass frame 2 of the present application, a hinge male portion 3 for connecting a temple is projected on the outside thereof, and the male male portion 3 is sandwiched by the female hinge portion 5 of the temple 4, and Since the recesses 7 and the protrusions 7 provided corresponding to the upper and lower surfaces and the upper and lower inner surfaces of the female hinge portion 5 are fitted to connect the lens frame 2 and the temple 4, the lens frame 2 and the temple are mounted. At the time of removal
The shape inside the frame 2 does not loosen or change, and the lens 1 does not come off from the frame 2.

Further, the concave portion 7 and the convex portion 7 which are provided respectively corresponding to the upper and lower surfaces of the male hinge portion 3 and the upper and lower inner surfaces of the female hinge portion 5 are fitted to each other, and the convex portion 7 is connected to the male male portion 3 of the hinge. At the time of attachment / detachment to / from the hinge female portion 5, it only protrudes to such an extent that it rubs against the surface having the concave portion 7. Therefore, when attaching and detaching the lens frame 2 and the temple 4, the convex portion 7 is made into the surface having the concave portion 7. Since it can be slid and can be smoothly performed with one touch, it can be easily performed even by an amateur, and the conventional screw pin and its screwing work are unnecessary, and as a result, the cost for connecting the temple can be reduced.

Also, by making the connection between the lens frame and the vine to be connected to it compatible, the user can select the vine according to his preference at the store of the eyeglass store and connect on the spot. effective.

Furthermore, there is an advantage that a spare vine can be prepared and the user can easily replace the vine depending on the intended use, while on the other hand, even when the vine is broken during use like sports glasses, it can be quickly replaced. Can respond.

Further, by using a colored or decorated annular slide member, it becomes an effective member as a charm point of the spectacles.

Furthermore, with this connection device, like a conventional screw pin,
There is also an advantage that the screw does not come loose.
