Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temple end which is one of the components of a spectacle frame, and more particularly to a temple end which can be easily adjusted by the user himself to obtain the best fit.

[0002]

2. Description of the Related Art The temple end of a spectacle frame is an important member for locking the spectacles to the user's ear, and the temple end mounting position and the curvature of the bent portion do not match the user's head size. This may impair the feeling of wearing and may cause the glasses to come off during use. Many of the conventional temple ends are made of a synthetic resin material that is curved in an arc shape, and when purchasing eyeglass frames, bend the bent part to match the head size of the purchaser at the retail store, It was necessary to readjust the length.

[0003]

However, this adjustment work requires skill and cannot be done in a sufficient amount of time in a mass-sales retail store, etc. whose motto is low-cost sales because of the labor cost. There were cases. or,
It is unavoidable that the spectacle frame gradually deforms during use, and sometimes it is necessary to readjust the entire spectacle frame including the temple end, but it is awkward to go to the retail store where you purchased it, so it is unwilling. However, there were many cases where the deformed eyeglass frames were worn as they were.

The present invention is intended to solve the above-mentioned conventional problems relating to the temple end of an eyeglass frame, and can be easily adjusted not only by an expert but also by the user himself, and is always the best. It is intended to provide a convenient temple end that provides a fit.

[0005]

According to the present invention, a temple insertion elongated hole 2 is formed along the shaft center on the front foreside of a temple end main body 1 made of a thermoplastic resin rich in spring property curved in an arc shape. By providing a bending member 8 which is provided with a plastic core material 4 made of a soft synthetic resin or a rubber covering the outer periphery of the metal core material 3 which is rich in plasticity at the rear edge side thereof, a circle made of a thermoplastic synthetic resin is also provided. A long hole 2 for temple insertion is provided along the axis on the front edge of the columnar temple connecting member 5, and the outer circumference of the metal core material 6 having a high flexibility is softened along the axis on the rear edge. The above problem is solved by connecting the bending member 11 covered with the covering material 4 made of synthetic resin or rubber.

[0006]

In the temple end of the first aspect of the invention, the front end of the main body 1 is heated prior to use, and then the rear end of the temple 7 is inserted into the long hole 2 for temple insertion to adjust the head size of the user. Adjust the insertion amount so that the length is suitable. The rear end of the inserted temple 7 is firmly fixed as the temple end body 1 is cooled. After determining the length of the temple 7, the temple end body 1
By bending the bending member 8 located at the rear end so as to fit the shape of the user's ear, it is possible to complete an eyeglass frame that best fits the size of the head of each user. The bending operation of the bending member 8 does not require any pretreatment such as heating, and can be easily performed by the user himself, and can be redone as many times as necessary. In addition, depending on the use situation, it is possible to make an adjustment such that the bending is large in order to prevent the falling off when there is a great movement such as sports, and the bending is small so as to be easily attached and detached during a normal use without a great movement.

Also in the temple end of the second invention, if the temple connecting member 5 is heated to adjust the insertion amount of the temple 7, and then the bending member 11 is bent to fit the user's ear, the user can do so. It is possible to complete a spectacle frame that fits the head dimensions of. In the temple end of the second aspect of the invention, the bending member 11 occupies most of the temple end and comes into contact with most of the upper and rear parts of the user's ear, and the bendable range is extremely large. Suitable for spectacles such as sunglasses, which are subject to intense movement.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of an embodiment of the temple end according to the first invention, in which 1 is a temple end main body made of a thermoplastic resin having a Shore D hardness of 60 or more and having a high spring property. It is formed in an arc shape so as to wrap around the upper and the rear of the ear, and a long hole 2 for temple insertion is provided on the front fore edge side along the axis. On the other hand, the tip of a metal core material 3 having high plasticity is fitted and joined to the rear edge side, and the outer periphery of this metal core material 3 is covered with a covering material 4 made of a soft synthetic resin having a Shore A hardness of 40 or more or a rubber. , Bending member 8
Has become.

As described above, the metal core material 3 is highly plastic,
Not only can it be bent easily by applying an external force, but it must also keep its shape until a new external force is applied, and copper wire rods, aluminum wire rods, mild steel wire rods, etc. can be used. Further, the metal core material 3 is not limited to a single wire material, but may be a material obtained by bundling or twisting two or more metal wires or a plate material. Further, it may have a notch 9 on the surface as shown in FIG. 3 or may have a through hole 10 as shown in FIG. In these examples, the adhesion between the metal core material 3 and the covering material 4 becomes stronger, and peeling of the covering material 4 during use is almost completely prevented. In the figure, 7 is a temple of the eyeglass frame.

Next, an embodiment of the second invention will be described with reference to FIG. Reference numeral 5 in the drawing denotes an arc-shaped temple connecting member, which is made of a thermoplastic resin having a Shore D hardness of 60 or more, and has a long hole 2 for temple insertion along the shaft core on the front fore side thereof. . On the other hand, the tip of the metal core material 6 having a high degree of plasticity is fitted and coupled to the rear edge side along the axis thereof. The metal core material 6 is formed in an arc shape in advance so as to wrap around the front and rear of the user's ear, but finally, the bending amount is determined while being tried on by each user. As in the case of the first aspect of the invention, the outer circumference of the metal core material 6 is covered with a covering material 4 made of a soft synthetic resin or rubber having a Shore A hardness of 40 or more to form a bending member 8. The material and shape of the metal core material 6 are exactly the same as those of the first invention.

[0011]

EFFECT OF THE INVENTION The temple end according to the present invention has the structure as described above, and since the bending member which is rich in plasticity and can be freely bent is attached to the rear portion, before heating or the like. The temple end can be easily adjusted by the user himself without any processing, and the adjustment at the store is minimal, reducing the selling cost and making it easy to buy the spectacle frame. Have the effect. In addition, it is possible to change the holding power of the glasses depending on the situation such as sports, normal daily life, and work, and it has excellent versatility for expanding the range of use of one glasses frame.
