Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of an eyeglass frame that regulates the opening angle of temple members.

In a conventional eyeglass frame, a front hinge is fixed to the inner surface of the end of the endpiece, a temple hinge is fixed to the inner surface of the end of the temple member, and the two hinges are supported by a single rotating shaft.

When a person opens the temple member via the hinge so that the front end surface of the endpiece and the front end surface of the temple member face each other in order to put on glasses, the front end surfaces of the endpiece and the temple member come into contact with each other. The contact limits the opening angle of the temple member.

However, in this conventional frame, when trying to replace the temple member with a new temple member, if the positional relationship between the temple hinge of the new temple member and the tip end surface of the end of the temple member is different from that of the old temple member,
The opening angle of the new temple member is different from the opening angle of the previous temple member.

Therefore, in order to prevent this opening angle from changing, the temple member must be manufactured so that the positional relationship between the temple hinge of the new temple member and the tip end surface of the end of the temple member is the same as that of the old temple member. First, strict precision is required when manufacturing the temple member.

An object of the present invention is to provide an eyeglass frame that does not require strict precision in order to prevent the opening angle of the temple members from changing when replacing the temple members.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 3 show a first embodiment, FIG. 1 is a perspective view of an eyeglass frame, and 1 is a rim member for holding lenses;
Reference numeral 2 designates an armor member fixed to the rim member 1 via a blow tube 1a, which will be described later, and 3 a temple member.

Elements 1 and 2 constitute the temple portion of the frame.

FIG. 2 is an enlarged partial sectional view of the connecting portion between the armor member 2 and the temple member 3, and FIG. 3 is a side view of this connecting portion taken along the line A--A.

In these figures, 1a is the aforementioned blow tip.

The end portion 2a of the armor member 2 is formed into a bifurcated shape as shown in FIG. 3, and the end portion 3a of the temple member 3 is inserted between the protruding ends 2a and 2c.

As clearly shown in FIG. 2, the front hinge 4 is fixed to the inner side surface 2d of the armrest member, and the temple hinge 5 is fixed to the inner side surface 3b of the temple member.

Hinge screw 6 pivotally supports hinges 4 and 5 and allows hinge 5 to rotate relative to hinge 4.

The above-mentioned hinge 4 protrudes toward the temple member 3 from the tip 2e of the end 2a of the endpiece member, and is attached to the temple member 3.
The end portions 3a are provided such that their tips 3C protrude from the hinge 5 toward the armouring member 2.

With the above configuration, when the temple member 3 is folded toward the front side (not shown), the temple member 3 is rotated clockwise around the hinge screw 6, and when the temple member 3 is opened, the first The state shown in FIGS.

The inner surface of the end of the temple member 3 that protrudes from the hinge 5 toward the armouring member 2 comes into contact with a surface 4a opposite to the inner surface 2d of the hinge 4, and the opening angle θ of the temple member 3 is regulated as shown.

In this embodiment, by bringing the front hinge 4 into contact with the inner surface of the end of the temple member 3, the temple member 3
Since the opening angle is regulated, a predetermined opening angle θ can be obtained without strictly determining the positional relationship between the temple hinge 5 and the temple member tip 3C.

Therefore, when replacing the temple member 3 with another temple member of the same shape, even if the positional relationship between the hinge of the new temple member and the tip of the temple member is slightly different from that of the old temple member, the predetermined opening angle θ will always be obtained. It will be done.

In addition, the tip 2e of the endpiece member and the tip 3C of the temple member
The gap 7 provided between the temple member and the temple member is to prevent the end of the endpiece member and the end of the temple member from coming into contact even if the positional relationship between the temple hinge and the end of the temple member in the replacement temple member varies somewhat. .

In addition, the gap 8a between the protruding portion 2b and the temple member 3 and the gap 8b between the protruding end 2c and the temple member 3 are such that when the temple hinge 5 is fixed to the temple member 3, the mounting position of the hinge 5 is This is to prevent the temple member 3 and the protruding ends 2b, 2c from coming into contact even if they are slightly shifted.

4 and 5 show a second embodiment of the invention.

This embodiment differs from the first embodiment in the connecting portion between the armor member 12 and the temple member 13.

FIG. 4 is a partial sectional view showing the same state as FIG. 2, and FIG. 5 is a sectional view taken along the line B--B.

As is clear from FIG. 5, the end 1 of the temple member 13
3a is formed into a bifurcated shape, and the end portion 12a of the armor member 12 is inserted between the protruding ends 13b and 13c.

Further, as shown in FIG. 4, the front hinge 14 is fixed to the inner side surface 12b of the endpiece member, and the temple hinge 15 is fixed to the inner side surface 13d of the temple member.

Hinge screw 16 pivotally supports hinges 14 and 15.

The end 12a of the armor member 12 mentioned above is the tip 12c.
The hinge 15 is provided so as to project from the tip 13e of the end portion 13a of the temple member toward the endpiece member 12, such that the hinge 14 projects toward the temple member 13 side.

When the temple member 13 is opened, it becomes the state shown in FIGS. 4 and 5, and the surface 15a facing the inner surface 13d of the hinge 15 is
comes into contact with the inner surface of the end of the armrest member 12 that protrudes from the hinge 14 toward the temple member 13, and the opening angle θ of the temple member is regulated as shown in the figure.

In this embodiment, the temple hinge 15 and the endpiece member 1 are
Temple member 1 is brought into contact with the inner surface of the end of temple member 2.
Since the opening angle of 3 is regulated, a predetermined opening angle θ can be obtained without strictly determining the positional relationship between the temple hinge 15 and the temple member tip 13e.

Therefore, when replacing the temple member 13 with another temple member of the same shape, the predetermined opening angle θ is always obtained even if the positional relationship between the hinge of the new temple member and the tip of the temple member is slightly different from that of the old temple member. It will be done.

The reason for providing the gaps 17, 18ai8b is the same as the reason for providing the gaps 7.degree. 8a, 8b in the first embodiment.

As described in detail above, according to the present invention, the end of one of the endpiece member and the temple member is brought into contact with the hinge fixed to the other member, so that the temple member is attached to the endpiece member. Regulate the opening angle.

Therefore, when replacing the temple member, it is not necessary to precisely manufacture the positional relationship between the temple hinge and the end surface of the temple member in order to prevent the opening angle of the temple member from changing as in the conventional case.
