That is, the lower side of the temple 102 is cut off to form a low step portion 103, and a spring 105 is stretched between a rear lower end of the armor 101 and a portion of the temple 102 in contact with the end of the low step portion 103.
The opening and closing of is performed by the hinge 104 provided on the upper half of the armor 101 and the front end of the temple 102.

[0004]

However, in the conventional example as shown in FIG. 9, the hinge 104 and the spring 105 are provided.
Since the arrangement position of is not on a straight line, a bending moment such as A1 ′ acts on the hinge 104, which hardens the operation of the hinge 104, wears it in a short period of time, and causes damage, and the spring 105. The side of the temple 102 opposite to the low-step portion 103 is not covered, and when the eyeglasses are worn, the hair of the wearer is pinched.
There was a risk of getting caught in 05.

Further, the glasses of FIG. 9 do not have a symmetrical shape in the design of the armor 101 and the temple 102,
The design lacked stability.

The present invention has been made in order to solve the above-mentioned problems of the prior art. The object of the present invention is to easily process and assemble members and replace parts, which is durable and durable. Adopting a structure that does not require unnecessary force on the hinges and temples, minimizes the exposure of the spring, reduces the risk of contact with the wearer, and is aesthetic. Also to provide good glasses.

[0007]

In order to achieve the above object, according to the present invention, one or a plurality of springs are provided for engaging the armor and the centroid of the contact section of the temple when the temple is raised. To stretch.

It is also possible to provide a plurality of springs at symmetrical positions with respect to the centroid in the contact cross section of the armor and the temple.

Further, a plurality of hinges are provided on the inner side of the rear end of the armor, and each of the plurality of hinges can pivotally support one of the temple members in a plurality of rows having a predetermined length from the front end of the temple. It is also preferable that one or a plurality of springs that are engaged with the substantially central portion of the rear end that is blunt between the plurality of rows of temple members and the approximately central portion of the branch portions of the plurality of rows of temple members are stretched.

Further, two hinges are provided on the inside of the rear end of the armor, and each hinge is capable of pivotally supporting one of double-row temple members of a predetermined length above and below the front end of the temple. It is characterized in that a spring which is engaged with a substantially central portion of the rear end which is blunt between the double-row temple members and a branch portion of the double-row temple members is stretched.

[0011]

With the spectacles of the present invention configured as described above, when the temple is tilted, it is biased by the spring to a raised state for use or a tilted state for storage, in which case the armor and temple The spring tension acts so that it overlaps the centroid of the abutting cross section, and unnecessary force (bending moment) is not applied to the hinge or temple. Also,
The load is evenly applied to multiple hinges.

Moreover, the risk of contact between the spring and the wearer is reduced.

Furthermore, it is possible to exert an aesthetic effect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to illustrated embodiments. (First Embodiment) FIG. 1 is a three-sided view of eyeglasses 1 to which the present invention is applied. FIG. 1 (a) is a right side view of the eyeglasses, FIG. 1 (b) is a plan view, and FIG. It is a front view. 2A is an enlarged plan view of the armor / temple portion, and FIG. 2B is an enlarged front view of the armor / temple portion.

FIG. 1 best illustrates the features of the present invention.
In FIG. 2A and FIG. 2B, L is the lens of the spectacles 1,
2 is a rim on which the lens 1 is fitted, and 3 is an armor attached to the left and right of the rim 2.

The armor 3 is provided with upper and lower hinges 5a and 5b inside the rear end thereof. The hinges 5a and 5b can pivotally support the ends 4a1 and 4b1 of the temple members 4a and 4b, which are double rows in a vertical direction and have a predetermined length longer than that of the spring 6 than the front end of the temple 4. . Further, the hinges 5a and 5b are attached to the end portions 4a1 and 4b1.
Corresponding to, the hinge part required to be supported is provided.

Reference numeral 6 is a spring, and the temple member 4
It is arranged between a and 4b, and is engaged with the approximately central portion 3a of the armored rear end and the branch portion 4c of the temple members 4a and 4b, and urges them in a direction to pull each other. At this time, the substantially central portion 3a of the armoring rear end and the branching portion 4c of the temple members 4a and 4b are located substantially in the centroid of the contact cross section of the armoring 3 and the temple 4. When the temple 4 is tilted, the spring 6 biases the temple 4 in a raised state for use or a tilted state for storage.

In FIG. 2 (a), the solid line is the erected state using the temple 4, and the spring 6 is biased by the required tension. In this state, the center of the tensioning force of the spring 6 is at the position of the centroid in the contact cross section of the armor 3 and the temple 4, so that the hinge and the temple can be urged without applying unnecessary force (bending moment). There is. Next, when the temple 4 is rotated to the position of arrow A1 in the collapsed state for storage, the tension of the spring 6 becomes maximum, and the temple 4 cannot be retained at this position. Then, when the temple 4 is rotated to the position of the tilted state where the arrow A2 is stored, the temple 4 is biased in the tilted state with a required tension weaker than the tension of the spring 6 at the position of the arrow A1.
