Abstract

PROBLEM TO BE SOLVED: To provide spectacles which can change a fitting state in mounting and are highly convenient while improving ornamentaility. SOLUTION: External threads 31c are confined into an external thread chamber 32c, by which the external threads 31c are put into a free state without being interfered in a turning direction to make an ear bend 32 freely turnable relative to an arbor 31. An arbor body 31d of the arbor 31 is previously subjected to bending and on the other hand, the ear bend 32 is so formed as to have different bending characteristics with respect to the force acted from the differences where the angle around the axial center are different. When the ear bend 32 is turned relative to the arbor 31, the ear bend 32 is made to obtain different curving shapes by the force that the ear bend receives from the arbor 31 previously subjecting to bending according to the turning positions thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temple and a pad which are one of members constituting an eyeglass frame.

[0002]

2. Description of the Related Art Conventionally, spectacles have been positioned not only for the purpose of correcting visual acuity but also as ornaments, and there is a demand for improved decorativeness.

In particular, temples and pads play a large role in fulfilling the decorative function.

[0004] Therefore, in addition to simply decorating the temple surface, for example, as disclosed in Japanese Unexamined Patent Publication No. 9-159973, the decoration member is configured to be rotatable, so that the decoration property is changed. What is known is.

[0005]

However, in the case of the prior art, even if the decorative member is rotatable, the color and the pattern are only changed, and the entire temple (modern shape) or the pad is used. Because there is a limit to change, there is still a limit to the improvement in decorativeness.

[0006] The main function of the temples and pads is to catch the ear and fit the face in the former case, and to fit the nose in the latter case. In some cases, it may be desirable to change the manner of fitting.

That is, for example, in a normal use of a temple, if it fits too much,
On the other hand, it may be uncomfortable or disturbing, so it is enough to be able to hold the glasses lightly to the extent that the glasses do not fall off. It is desirable that the glasses be sufficiently fitted so that the glasses do not come off even if they move violently.

The same can be said for a pad.

Therefore, there has been a demand for a temple or pad that can easily change the manner of fitting according to the use mode.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to improve the decorativeness and to change the fitting state at the time of mounting. The object of the present invention is to provide a temple and a pad excellent in the above.

[0011]

According to the present invention, there is provided a temple having a core and a modern having a fitting hole into which the core is fitted. The mandrel is preliminarily bent, and the modern is provided rotatably with respect to the mandrel, and the modern is capable of responding to forces applied from different directions around the rotation axis. It is characterized by having different bending characteristics.

Therefore, by rotating the modern with respect to the mandrel, the bending curve shape of the modern changes due to the force received by the mandrel from the mandrel.

When the modern is at a predetermined rotation position with respect to the metal core, a first use state in which the modern has a predetermined bending curve shape due to a force received from the bent metal core. And when the modern is in a different rotational position with respect to the mandrel than in the first use state,
It is preferable that the modern has a second use state in which a bending curve shape different from the first use state is obtained by a force received from the bent cored bar.

Thus, in the first use state and the second use state, the design changes and the shape of the bending curve changes, so that the fitting state at the time of mounting can be changed.

On the surface of the modern, a slit is formed which is substantially perpendicular to the rotation axis, and is opposite to the surface on which the slit is formed with respect to ease of bending toward the surface on which the slit is formed. It is preferable to provide different bending characteristics by facilitating bending in the bending.

Thus, different bending characteristics can be provided with a simple configuration in which a slit is provided.

Preferably, the cored bar is provided with a male screw, and the modern fitting hole is provided with a screw corresponding to the male screw.

Thus, the modern can be easily attached to and detached from the mandrel.

Preferably, the modern fitting hole is provided with a male screw chamber which does not interfere with the turning direction of the male screw on the temple end side than the female screw.

Thus, the modern is rotatably supported with respect to the core metal by screwing the male screw into the male screw chamber until the male screw fits in the male screw chamber.

Further, in a temple having a cored bar and a modern having a fitting hole into which the cored bar is fitted, a male screw is provided on the cored bar, and the modern fitting hole is provided in the modern fitting hole. A screw is provided to correspond to the male screw,
A male screw chamber is provided on the temple end side of the female screw so as not to interfere with the male screw in the rotation direction.

Accordingly, by screwing the male screw into the male screw chamber until it fits in the male screw chamber, the modern is rotatably supported with respect to the cored bar.

[0023] It is preferable that each of the moderns is provided with a different decoration depending on a position rotated with respect to the metal core.

Thus, the decoration such as color and pattern can be changed by rotating the modern with respect to the mandrel.

Further, according to the present invention, in a pad having a pad core and a pad body having a fitting hole into which the pad core is fitted, the pad core is previously bent. In addition, the pad body is provided rotatably with respect to a pad core, and the pad body has different bending characteristics with respect to forces applied from different directions around the rotation axis. When the pad body is at a predetermined rotation position with respect to the pad core, a first use state in which the pad body has a predetermined bending curve shape by a force received from the bent pad core; When the pad main body is at a rotational position different from that in the first use state with respect to the pad core, the pad main body receives the first force by the force received from the bent pad core. Use letter Second made different deflection curve shape and
And a use state.

Thus, in the first use state and the second use state, the design changes and the bending curve shape changes, so that the fitting state at the time of mounting can be changed.

[0027]

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the dimensions of the components described in this embodiment,
The materials, shapes, relative arrangements, and the like are not intended to limit the scope of the present invention only to them unless otherwise specified.

A temple according to an embodiment of the present invention will be described with reference to FIGS.

FIG. 2 is a schematic structural perspective view of the entire eyeglass frame.

As shown in FIG. 2, the spectacle frame 100 generally includes a rim 1 for holding a lens, a tongue 2 provided at both ends of the front, and a temple 3 provided at a portion from the hinge to the ear. And a pad 4 that is brought into contact with the nose to support the glasses.

The modern 32 constituting the temple 3 according to the embodiment of the present invention is rotatably provided as shown in FIG.

That is, FIG. 1B shows a state in which the modern 32 is rotated by 90 degrees from the state shown in FIG. 1A, and FIG. 1C shows the state shown in FIG. A state in which the modern 32 is rotated 180 degrees from the state is shown.

In the illustrated example, the state becomes stable in the state shown in FIG. 1A (first use state) or the state shown in FIG. 1C (second use state). FIG. 1 (B) shows a state in the middle of the turning operation.

The turning mechanism will be described with reference to FIGS. 3 and 4.

FIG. 3 is a schematic structural perspective view showing a state of the core metal 31 fixed to the chi 2, FIG. 4 is an explanatory view for explaining a schematic structure of the temple 3, and FIG. FIG. 4B is a schematic configuration perspective view showing a state before assembling each member constituting the temple 3, and FIG. 4B is a schematic configuration sectional view showing a state after assembly.

As shown in FIG.
And Modern 32.

The metal core 31 is composed of a frame 31a corresponding to the chisel 2a, a stopper 31b for regulating the position of the modern 32 in the rotation axis direction, a male screw 31c, and a metal core body 31d. Have.

The modern 32 includes a fitting hole 32a for fitting the core 31 and a male screw 31c provided on the core 31.
And a male screw chamber 32c provided on the temple end side of the female screw 32b and not interfering with the male screw 31c in the rotation direction.

With the above configuration, the core metal body 31d of the metal core 31 is fitted into the fitting hole 32a of the modern 32,
Modern 32 for the male screw 31c provided on the cored bar 31
The screw 32b is screwed in so that the male screw 3
The screw 1c is screwed in until it is housed in the male screw chamber 32c provided in the modern 32.

In order to store the male screw 31c in the male screw chamber 32c provided in the modern 32, the male screw 31c is required.
Is provided on the modern 32 from the end of the stopper 31b, so that it is necessary to provide the screw 32b at a position at least separated by the length in the rotation axis direction of the screw 32b.

As described above, the screw 31c is connected to the male screw chamber 32c.
The modern screw 32 is freely rotatable with respect to the mandrel 31 without being interfered with the turning direction.

On the other hand, a modern 32
The position of the tip is regulated by a stopper 31b provided on the metal core 31, and the female screw 32b is
Therefore, the movement in the rotation axis direction is restricted.

As described above, with a very simple configuration, the modern 32 can be freely rotated only in the rotating direction with respect to the metal core 31, and the modern 32 is rotated with respect to the metal core 31. By making the decoration different according to the position, the design can be changed by a simple operation.

When it is desired to remove the modern 32 from the metal core 31, it is necessary to apply a rotational force in a direction opposite to the screwing direction while applying a force in a direction in which the modern 32 is removed from the metal core 31. Then, since the screw comes off, the modern 32 can be easily removed.

Therefore, it is possible to easily perform maintenance such as repair or replacement, or part replacement (replacement of the modern 32) for changing the design.

Here, in the temple according to the embodiment of the present invention, not only is it possible to change the color, pattern, etc., by rotating the modern 32, but also to rotate the modern 32. By doing so, the configuration (deflection curve) of the entire temple can be changed.

A configuration in which such a shape (deflection curve) can be changed will be described with reference to FIGS. 3 and 5 to 7.

First, the metal core 31 is made of a metal having relatively high rigidity (for example, shape memory alloy (NT)), and the metal core 31d is fitted inside (see FIG. 3) so as to fit the head (face). (In the direction of the arrow).

On the other hand, the modern 32 is made of plastic or the like having lower rigidity than metal, and has different bending characteristics with respect to forces applied from different directions around the axis.

Thus, when the modern 32 is rotated with respect to the mandrel 31, the force received from the preformed bent mandrel 31 is applied to the modern 32 according to the turning position.
In order to obtain a different curved shape, the shape of the entire temple 3 changes.

Hereinafter, as a more specific example, the modern 32 is shifted by 180 degrees from the state of FIG. 1A showing the first use state and the state of FIG. 1A showing the second use state. A configuration in which there are two use states as in the case of FIG. 1C rotated and the shape of the temple changes in each use state will be described with reference to FIGS.

FIG. 5 is a schematic configuration diagram of the modern 32. FIG. 5A is a sectional view taken along a plane perpendicular to the rotation axis, and FIG. 5B is a perspective view of the whole. .

As shown in the figure, the modern 32 has an elliptical cross-sectional shape, and is configured such that the thickness B in the vertical direction is larger than the thickness A in the horizontal direction.

Therefore, the modern 32 is easier to bend in the horizontal direction than in the vertical direction, and when the bending direction of the metal core 31 matches the horizontal direction of the modern 32,
By the force received from the cored bar 31, a predetermined bending curve is maintained to maintain a stable shape and a position in the rotating direction.

The bending direction of the core metal 31 is
In the state where they do not coincide with each other in the horizontal direction, the modern 32 is hardly bent as compared with the state where they coincide with each other, so that the state becomes unstable and cannot be maintained at that position.

This will be described in more detail. In contrast to the easiness of bending the modern 32 at a certain position in the rotation direction with respect to the metal core 31, the modern 32 is harder to bend when rotated in any direction. In such a case (in the above example, when they coincide in the horizontal direction), the position is stabilized at that position.

On the other hand, if it is easy to bend from a certain position in one direction (if it does not coincide with the horizontal direction in the above example), the core metal body 31d
Since the slip occurs between the modern 32 and the fitting hole 32a of the modern 32, the modern 32 automatically rotates in a direction in which the modern 32 is more easily bent, and rotates to the above stable position.

By increasing the frictional force between the core metal main body 31d and the fitting hole 32a of the modern 32, the modern 32
The modern 32 can be maintained at a predetermined rotation position without causing the modern 32 to rotate without permission.

In the temple according to the present embodiment, the modern 32 is configured such that the bending characteristics are different from each other in the two horizontal directions.

An example of such a configuration in which the bending characteristics are different will be described with reference to FIGS. 6 and 7. FIG. FIG.
FIG. 7 is a schematic configuration perspective view of the modern 32, and FIG. 7 is an explanatory view for explaining bending characteristics, and is a top view showing a state of a bent shape when a force is applied from each direction.

As shown in the figure, a plurality of slits 32d substantially perpendicular to the rotation axis are formed on one surface in the horizontal direction.

By providing the slit 32d in this way, considering the case where the same force acts on the same position from the P direction and the Q direction in FIG. 7B, as shown in FIG. 7B, the thickness is reduced by the amount provided with the slit 32d, and the slit 32d is also in a direction in which the slit 32d is widened. The angle α between the inner surfaces becomes smaller.

On the other hand, when a force F is received from the P direction,
As shown in FIG. 7C, the side surfaces of the inner surface of the slit 32d are in contact with each other, so that the inner surface of the slit 32d is less likely to bend than when the force is applied from the Q direction, and the angle β between the bent inner surfaces is determined.
Is larger than the angle α.

As described above, the bending characteristic can be changed by the simple structure in which the slit is provided. In addition,
It goes without saying that the bending characteristics can be appropriately set according to the size and shape of the slit or the number thereof.

By changing the bending characteristics in this manner, the modern 32 is turned upside down with the surface provided with the slit 32d (for example, the state shown in FIG. 1A) and the surface not provided with the slit 32d. (For example, the state shown in FIG. 1C), a different bending curve shape is obtained by the force received from the core metal 31 that has been subjected to the bending process in advance.

More specifically, if the surface provided with the slits 32d is set to the front (outside), the shape becomes more curved, and if the surface not provided with the slits 32d is set to the front (outside), the shape becomes more linear. Becomes

As described above, by making the modern 32 have different bending characteristics with respect to forces applied from different directions around the axis, the modern 32 can be rotated with respect to the metal core 31. The shape of the modern 32 can be changed not only in color and pattern but also in the entire temple 3 or the shape of the modern 32, and the width of the design can be increased, and the decorativeness can be improved.

In addition, the configuration in which the shape of the bending curve can be changed as described above contributes not only to the improvement of the decorativeness but also to the improvement of the functionality that can be adapted to the usage mode. Become.

That is, as described above, it is preferable to fit the head (face) lightly rather than fitting the head (face) too much during normal use. It is preferable to make it fit sufficiently.

Therefore, during normal use, if the shape is more linearly bent, it can be used in a lightly fitted state.
If a more curved bending shape is used to hold up to the position of the back of the head, a sufficient fit can be achieved.

As described above, the modern 32 is rotated with respect to the cored bar 31 so that the bending curve shape thereof can be changed, so that the decorativeness can be improved and the mounting time can be improved. The fit state can be changed, which is convenient.

In the above description, a case is described in which a slit is provided as a configuration for giving different bending characteristics to forces applied from different directions around the axis of the modern 32. It is not limited to this.

For example, different bending characteristics may be provided depending on the modern sectional shape, different bending characteristics may be provided by performing bending in a predetermined direction in advance, or different bending characteristics may be provided by using a plurality of materials. You may.

Further, in the above description, the case where there are two use states (two kinds of states in which a stable rotation position is maintained) has been described. However, the present invention is not limited to this, and it can be used in a plurality of states. You may do it.

For example, the modern sectional shape is a regular polygon, and it is easy to bend only in the direction perpendicular to each surface. A plurality of use states can be provided by making it easy to bend in a plurality of directions.

As described above, it is possible to stabilize the modern at an arbitrary rotation angle by increasing the frictional force between the fitting hole provided in the modern and the core metal.

Here, as described above, when the modern is constructed so that it can be used at a plurality of rotation positions or arbitrary rotation positions, the decoration (color or pattern) is changed at each position, and By changing the shape of the bending curve, a plurality of designs can be changed, and a plurality of fit states can be changed.

As a preferred example of providing a plurality of bending curves, a modern section is defined as a regular polygon, and each surface has
This can be easily realized by providing slits having different shapes, numbers, and arrangement positions.

In the illustrated example, the configuration in which the modern extends to the vicinity of the wisdom (long modern) has been described as an example. However, the modern (short modern) provided only around the part to be heard can be used. Needless to say, the same can be applied.

Further, in the description so far, the case where the temple is configured to bend inward (head side) has been described as an example. However, the present invention is not limited to this, and the temple is configured to bend downward (to be hooked on the ear). Is also good.

Such a case will be described with reference to FIG. FIG. 8 is a schematic configuration diagram of a temple according to an embodiment of the present invention. FIG. 8A shows a case of the long modern 33a, FIG. 8B shows a case of the short modern 33b, and FIG. C) shows a cross section perpendicular to the axis of the bent portion of the modern.

As shown in FIG. 8C, the long modern 33a
The short modern 33b has an elliptical cross section having a small vertical thickness and a large horizontal thickness, and is configured to be easily bent in the vertical direction. The lower part 31 (the core metal body 31d) is bent in advance on the lower side (the side on the ear).

Further, the long modern 33a and the short modern 33
b is configured such that the bending characteristics are different from each other also in two longitudinal directions. Although not particularly shown, for example, a slit may be provided on one of the surfaces as in the above-described example.

With the above configuration, the long modern 33a
By rotating the short modern 33b with respect to the mandrel 31, the angle γ in the figure can be changed, so that the design can be widened and the fit to the ear can be changed.

Although the description has been given of the temple, a similar function can be applied to the pad. Hereinafter, a case where the present invention is applied to a pad will be described with reference to FIG.

FIG. 9 is a schematic structural view of a pad according to an embodiment of the present invention. FIG. 9A is a schematic structural perspective view showing a state near the pad before assembling, and FIG. 9B is a side view of the pad body. FIG.

As shown in the figure, the pad 4 generally includes a pad core 41 fixed to the rim 1 and a pad body 42 rotatably attached to the pad core 41. In the illustrated example, the pad foot and the pad core are integrated into a single component, but the pad core in the case where the pad foot and the pad core are separate components is also an embodiment of the present invention. Can be applied.

In the case of a pad, the pad core 41 corresponds to the core metal in the case of the temple, and the pad body 42
Corresponds to the modern in the case of the temple, and can exhibit the same function as the case of the temple.
The basic operation and the like are the same as those in the case of the temple, and thus the details will be omitted and will be briefly described below.

That is, the pad main body 42 is provided with a fitting hole 42a for fitting the pad core 41, and by fitting the pad core 41 into the fitting hole 42a, the pad main body 42 is 41 can be freely rotated.

As in the case of the temple described above, the pad core 41 also receives a screw and the fitting hole 42a of the pad body 42 is provided with a female screw or a male screw chamber, so that the pad core 41 can rotate freely and securely. It is also preferable to adopt a structure for preventing the pad body 42 from falling off. However, considering that the pad body 42 is lightweight, it is sufficient to use only the frictional force between the fitting hole 42a and the pad core 41. Since it is possible to prevent the main body 42 from falling off, it is possible to adopt a configuration in which no screw mechanism is provided.

The pad core 41 is preliminarily bent, while the pad body 42 has different bending characteristics with respect to forces applied from different directions around the axis. As in the case of the temple, when the pad body 42 is rotated with respect to the pad core 41, the pad body 42 is rotated by the force received from the previously bent pad core 41 in accordance with the rotational position. In order to obtain a different curved shape, the shape of the entire pad 4 changes.

Therefore, as in the case of the temple, the decorativeness can be improved, and the state of fitting to the nose can be changed, which is excellent in convenience.

Note that, as shown in FIG.
By providing a plurality of convex portions 42b only on one of the two surfaces (to be brought into contact with the nose) used by the user, not only the change of the fitting state due to the change of the bending curve shape but also the change of the frictional force It is also possible to make it possible to change the fit state.

[0094]

As described above, according to the present invention, by turning the modern with respect to the mandrel, the bending curve shape can be made different, so that the decoration can be improved and It is possible to change the fit state of the camera, which is convenient.

With a simple configuration in which a slit is provided on the surface of the modern, different bending characteristics can be provided.

By providing a screw on the metal core and providing a female screw and a male screw chamber in the fitting hole of the modern, the modern can be freely rotated with respect to the metal core with a simple configuration.

In modern, decorations such as colors and patterns can be changed by giving different decorations in accordance with the position rotated with respect to the cored bar.

Further, by rotating the pad body with respect to the pad core, the shape of the bending curve can be made different, so that the fitting state at the time of mounting can be changed while improving the decorativeness. It is excellent in convenience.
