Description

[Detailed explanation of the idea] The present invention relates to an improvement of a multifocal eyeglass frame.

The purpose of the present invention is to provide a frame body suitable for bifocal glasses, which allows the nose piece to be moved up and down within a certain range.

In order to satisfy the above object, the present invention is constructed as follows.

That is, in the present invention, the nose piece 1 is pivotally attached to the tip of the support rod 2, and the support rod 2 and the mounting rod 5 protruding close to the central connecting piece 4 of the frame 3 have one end hollow. Both rods 2 and 5 are pivoted in a hollow part 6 by a pin 7 so as to be movable up and down, and a spherical member 9 is pressed against which the tips of the rods 2 or 5 inserted into the hollow part 6 come into contact. It is characterized in that it is resiliently accommodated in the hollow portion 6 via means 8, and that the tip portion 12 of the rod 2 or 5 is formed to protrude so as to be resiliently pressed by the spherical member 9 at either the upper or lower position thereof. be.

In the embodiment shown in FIGS. 1 to 3, a hollow part 6 is formed in the support rod 2, and in the embodiment shown in FIGS. This figure shows the reverse state in which the spherical member is accommodated. In particular, in FIGS. 6 and 7, two semi-annular bearing pieces 10 are protruded from the mounting rod 5 to pivotally support the pin 7. .

Therefore, even if the structure of the embodiment shown in FIGS. 1 to 3 is reversed, the object of the present invention can be achieved.

Note that the pressing means 8 is not limited to the illustrated spring, but may also be rubber or the like.

In order to pivotally support the nose piece 1, the tip of the support rod 2 may be bent into a pin shape as shown in the figure, or alternatively, another pin may be used for pivotally mounting.

Further, in the figure, 11a and 11b are notches provided opposite to each other at the open end of the hollow portion 6 so as not to interfere with the movement of the support rod 2 or the mounting rod 5.

Furthermore, as shown in Figure 4 A9 and C, the tip 1 of the mounting rod 5
2 can be formed into various deformed tip portions 12 a, 12 b, 12 C, etc. so as to reliably contact the spherical member 9.

That is, as is clear from the second diagram, the tip portion 12 is
The tip end is located on the axis of the rod 5 passing through the pin 7, so that it is sufficient that the support rod 2 is stable in each of the upper and lower states.

Since the present invention has the configuration described above, by moving the frame 3 upward or downward while wearing glasses, the support rod 2 can be moved upward or downward.
As shown in FIG. 2, the spherical member 9 is brought into elastic contact with the tip 12 of either the support rod 2 or the mounting rod 5 by the acting force of the member 8 that presses the spherical member 9 provided inside, and thereby It can be dropped while moving upward or downward.

At this time, since the tip 12 of the rod 2 or 5 is positioned on its longitudinal axis, the spherical member 9 comes into elastic contact with either side of the tip 12, and as a result, the nose piece 1 It has the effect of stably holding the top and bottom lids.

Therefore, when using bifocal glasses, it is possible to see lenses for distance or near points without having to move the eyes excessively as in conventional glasses, and reliable operability is obtained, which is convenient in practice.

[Brief explanation of drawings]

The drawings show a multifocal eyeglass frame according to the present invention; FIG. 1 is a perspective view of the first embodiment, FIG. 2 is a partially longitudinal front view of the main parts of the same, and FIG. 3 is a plan view of the same. , FIG. 4 is a side view showing another example of the shape of the tip of the support rod 5, FIG. 5 is a longitudinal sectional front view of a part of the main part of the second embodiment, and FIG. 6 is a part of the main part of the third embodiment. The longitudinal front view and FIG. 7 are the same plan views.

Claims (1)

[Scope of utility model registration request] The nose piece 1 is pivotally attached to the tip of a support rod 2, and the support rod 2 and a mounting rod 5 protruding from and in close contact with the center connecting piece 4 of the frame body 3 are as follows:
One of the rods is formed hollow, and both rods 2.5 are pivotally mounted in the hollow part 6 by pins 7 so as to be movable up and down.
A spherical member 9, with which the tip of the rod 2 or 5 inserted into the rod contacts, is compressed and housed in the hollow portion 6 via the pressing means 8, and the tip 2 of the rod 2 or 5 is pressed at either the upper or lower position. A multifocal eyeglass frame characterized in that the spherical member 9 is formed to protrude so as to be elastically compressed.
