Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to spectacles and spectacle frames, and more particularly to a technique relating to a temple and a temple connecting mechanism.

[0002]

2. Description of the Related Art Generally, temples of spectacles are rotatably provided through a connecting mechanism such as a hinge, and when the spectacles are stored in a case, the temples can be folded to be stored. It is like this.

As a folding structure of a temple, a temple is generally of a type in which a temple is rotated about 90 ° in a horizontal direction about a rotation axis provided substantially vertically, but recently, a temple having a substantially horizontal rotation axis is used. There is also a type in which the temple is rotated so as to draw a conical surface of rotation as the center (in this specification, the upper direction is based on the direction of the eyeglass when the eyeglass is worn in the upright position. , Downward, vertical, horizontal, horizontal, vertical, etc. shall be used.)

An example of the latter is, for example, Japanese Patent Laid-Open No. 8-2.
The one disclosed in Japanese Patent No. 34145 is known. The configuration will be briefly described with reference to FIG.

In this spectacle 100, the wisdom 101 and the temple 102 are connected via the hinge 103, and the hinge 10
The rotation axis 104 of No. 3 is inclined inward from the temple 102 in the unfolded state and is provided substantially horizontally.

The temple 102 in the unfolded state begins to move downward from that position, and the inner surface of the temple 102 is rotated about the axis 104.
It is turned by about 180 ° and folded at a position along the lens 105 (storage operation).

On the other hand, when opening the temple 102, the temple 102 is rotated in the direction opposite to the storing operation (expanding operation). Then, the tip end of the temple 102 is brought into contact with the wisdom 101, and the tip end of the wisdom 101 is brought into contact with the temple 102, thereby positioning (rotating) the temple 102.

Since this type of temple 102 can operate not only in the horizontal component direction but also in the vertical component direction,
When an external force is applied, it has the advantage that it is easily dispersed and released, and is unlikely to be deformed or damaged.

[0009]

However, in the structure as described above, the temple 102 freely rotates between the deployed state and the stored state without receiving a restraining force. At the time of wearing, the temple 102 rocked according to the direction of the eyeglasses, which was inconvenient to handle.

Further, since the temple 102 in the unfolded state is only positioned by abutting the tip of the temple 102 against the tip 101,
One way (ie, more temples 1
Although the rotation prevention of 02 in the direction in which it rotates is attempted, the engagement is easily disengaged when an external force acts in any other direction. Therefore, when an external force that lifts the front part of the spectacles is applied by vigorous exercise while wearing the spectacles or receiving some impact, the temples 102 are disengaged and the spectacles are displaced or fallen off. Could lead to

In this respect, in the former type of glasses in which the temple rotates horizontally, by incorporating a spring component in the hinge,
A so-called spring hinge may be used to bias the temple so that it is stable in the deployed state or the stored state.

Therefore, it is conceivable to adopt such a structure for the latter type of glasses to solve the above problem, but since the structure of the connecting mechanism is completely different between the former type and the latter type, the conventional spring is used. The hinge technology cannot be applied as it is. In addition, it is not preferable to add a spring component to the coupling mechanism because the structure is complicated, the coupling mechanism and the temple are enlarged, the number of components is increased, the design is difficult, and the cost is increased.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide spectacles and spectacle frames which have a simple structure and improve the handleability and stability of the temple. It is in.

[0014]

In order to achieve the above object, in the present invention, a temple and a front member are provided with the temple so as to rotate between a deployed state and a stored state. In a pair of eyeglasses including a connecting mechanism for connecting, the temple rotates while flexibly deforming itself,
The component of the restoring force that acts in the direction of rotating the temple should be directed in the direction of rotating the temple to the expanded state near the deployed state, and should be in the direction of rotating the temple to the stored state near the stored state. Is characterized by.

In the present specification, the "unfolded state" refers to a state in which the temples should be formed when wearing the spectacles, and a state in which the temples and the temples form an angle of approximately 90 °. On the other hand, the "stored state" refers to a state in which the temples are folded when the glasses are not used, such as when the glasses are stored in a case, and the front portion of the glasses and the temples are substantially overlapped.

Further, in the present specification, the "front side member" refers to a member that is connected to the temple among the members that form the front portion of the spectacles, and is, for example, a spectacle frame member such as a rim, eyebrows or blow bar. Alternatively, “wisdom” provided on a lens, a filter, or the like corresponds to this. If the temples are directly connected to the lens or filter,
The "lens" or "filter" corresponds to the front member.

According to the above structure, since the temple is bent and deformed as the temple rotates, a restoring force for restoring the original shape of the temple is generated. That is, a force for operating the temple is generated as a spontaneous force of the temple itself, independently of the external force applied by the person who operates the temple. The temple voluntarily rotates due to a component of the restoring force that acts in the direction of rotating the temple (hereinafter, this component force is referred to as "rotation component force").

In the present invention, the rotational component force is set so as to turn the temple into the deployed state in the vicinity of the deployed state and toward the stored state in the vicinity of the stored state. Therefore, the temple in the rotating state is rotated toward the deployed state or the stored state by its restoring force, and is stabilized at the position in that state.

Therefore, in the above construction, the temple can be easily expanded and stored, and
It is possible to prevent the temple from rotating in the deployed state and the stored state, and it is possible to improve handleability and stability.

Further, since these actions are exhibited by the bending of the temple itself and its restoring force, it is not necessary to add a spring component or other components, and the structure is simplified,
It is also possible to reduce the number of parts, facilitate the design, and reduce the cost.

In addition, the above-described structure also applies to the eyeglasses of the type in which the temples are connected so as to rotate between the deployed state and the stored state about the pivot axis provided substantially vertically, and the temples in the deployed state. A type in which the temple is connected so as to rotate between a deployed state and a stored state with the inner surface side of the temple centering on a rotation axis that is tilted inwardly and is substantially horizontal It can also be suitably used for eyeglasses.

As one aspect of the present invention, for example, eyeglasses including a temple and a connecting mechanism for connecting the temple to a front member so that the temple rotates between a deployed state and a stored state. In the above, the temple has two flexible linear members whose relative movement in the extending direction is regulated at the temple end side and which extends to the connecting mechanism. It is preferable that the distal ends of the flexible linear members are separately rotatably connected by the connecting mechanism so as to be rotatable about rotation axes provided substantially parallel to each other in the vertical direction.

According to this structure, when the temple is rotated, the distal ends of the two flexible linear members try to rotate so as to draw different rotation trajectories due to the restraint of the connecting mechanism. On the other hand, on the rear end side of the flexible linear member, a force that restricts the relative movement of both members in the extending direction acts. As a result of the opposing forces acting on the front end side and the rear end side of the flexible linear member in this way, bending deformation occurs in at least one of the two flexible linear members.

The restoring force of the bending deformation is determined by the pivotal fulcrum of the flexible linear member on the leading end side (point constrained by the connecting mechanism) and the regulating point on the rear end side (the other flexible linear member). It acts in the direction of a straight line connecting the member and the point where relative movement is restricted. Then, of this restoring force, with respect to a plane that is orthogonal to a straight line (hereinafter, referred to as “virtual center line of temple”) connecting the midpoint of each rotation fulcrum of the flexible linear member and the regulation point. The components in the parallel directions act as a force (rotation component force) for voluntarily rotating the temple.

In a state where neither of the two flexible linear members is flexed and deformed (first state), since no restoring force is generated, the rotational component force becomes zero.

When the temple is rotated downward from the first state, the distance between the regulation point and the lower rotation fulcrum is reduced, so that the lower (front side in the rotation direction) flexible linear member. Is flexibly deformed, and a rotational component force is generated in a direction to return the temple to the first state. On the contrary, when the temple is rotated upward from the first state, the distance between the regulation point and the upper rotation fulcrum is reduced, so that the upper flexible linear member bends. It is deformed, and a rotational component force is generated in the direction of returning the temple to the first state.

Therefore, the rotational component force acts in the direction of rotating the temple toward the first state in the vicinity of the first state (range within approximately ± 90 ° around the first state). .

A state in which the temple is rotated upward or downward from the first state to a position of 90 ° (second state)
Then, since the acting direction of the restoring force overlaps (becomes parallel to) the virtual center line of the temple, the rotational component force becomes zero.

When the temple is rotated beyond the second state, an angle is created between the acting direction of the restoring force and the virtual center line of the temple, so that the rotational component force acts again. However, since the positive / negative of the angle is inverted from that in the first state to the second state, the action direction of the rotational component force is opposite. In other words, the rotational component force acts in the direction of promoting the rotation of the temple.

From this point, the torque exerted on the regulation point by the restoring force of the flexible linear member on the front side in the rotation direction causes
The flexible linear member on the rear side in the rotation direction also begins to bend. The rotational component force of the restoring force of the flexible linear member on the rear side in the rotational direction acts in the direction opposite to the rotational component force by the flexible linear member on the front side in the rotational direction.

As the temple is rotated, the magnitude of the rotational component force of both members approaches, and when the temple is rotated about 180 ° from the first state, the rotational component of both members is rotated. The forces are just in balance (the third state). That is, in the third state, when viewed as the whole temple, the component of the restoring force that acts in the direction of rotating the temple becomes zero.

When the temple is rotated upward from the third state, the amount of deformation of the flexible linear member on the rear side in the rotational direction increases, and the amount of deformation of the flexible linear member on the front side in the rotational direction increases. Becomes smaller, a rotational component force is generated in the direction of returning the temple to the third state. Conversely, even if the temple is rotated downward from the third state, the rotational component force is also generated in the direction of returning the temple to the third state.

Therefore, the rotational component acts in the direction of rotating the temple toward the third state in the vicinity of the third state (a range of approximately less than ± 90 ° around the third state). .

According to the above construction, the temple in the rotating state is rotated toward the first state and the third state by its own restoring force, and is stabilized at the position of the state. .

Therefore, the temple can be easily rotated, and the temple can be prevented from rotating, so that the handleability and the stability can be improved.

Further, since these actions are exhibited by the bending of the temple itself and its restoring force, it is not necessary to add a spring component or other components, and the structure is simplified,
It is also possible to reduce the number of parts, facilitate the design, and reduce the cost.

It is preferable that the first state is a temple expanded state and the third state is a temple stored state.

Thus, the temples can be easily expanded and stored, and the temples can be prevented from rotating in the expanded and stored states, thereby further improving the handleability.

Further, according to one aspect of the present invention, for example, with respect to the temple, the inner surface side of the temple is centered on a rotation axis which is inclined inwardly and is substantially horizontal to the temple in the expanded state. In a pair of spectacles including a connecting mechanism for connecting the temple to a front member so as to rotate between a deployed state and a stored state while being directed toward a rotation axis, the temple is a relative member in the extending direction. Movements are regulated from each other on the temple end side, and two flexible linear members extending to the connecting mechanism are provided, and the tips of the two flexible linear members are substantially vertical. Even if the configuration is adopted in which they are separated from each other and are separately connected by the connecting mechanism, the same operation as described above can be achieved.

Further, according to one aspect of the present invention, for example, with respect to the temple, the inner surface side of the temple is centered around a rotation axis line that is inclined inwardly and is substantially horizontal with respect to the temple in the expanded state. In a pair of spectacles including a connecting mechanism for connecting the temple to a front member so as to rotate between a deployed state and a stored state while being directed toward a rotation axis, the temple is a relative member in the extending direction. Movements are regulated from each other on the temple end side, and two flexible linear members extending to the coupling mechanism are provided, and the tips of the two flexible linear members are Even if a structure in which the flexible linear members of the book are connected by the connecting mechanism so as to rotate while drawing the surfaces of rotation that are not similar to each other is employed, the same operation as described above can be achieved. .

Further, in each of the above aspects, it is also preferable that the temple is made of one flexible linear member whose both ends are bent to extend to the connecting mechanism.

According to this structure, since the temple can be composed of a single member, it is possible to further reduce the number of parts.

Further, the spectacle frame according to the present invention is constructed as follows. It should be noted that any of the spectacle frames listed below can achieve the same effects as the spectacles described above.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be illustratively described in detail below with reference to the drawings. However, the dimensions of the components described in this embodiment,
Unless otherwise specified, the material, the shape, the relative arrangement, and the like are not intended to limit the scope of the present invention thereto.

First, with reference to FIGS. 1 and 2, the overall structure of the eyeglasses and the eyeglass frame according to the embodiment of the present invention will be described.

FIG. 1 is a top view of the spectacles viewed from substantially above. FIG. 2 is a perspective view showing FIG. 1 from an angle parallel to the rotation axis of the temple. In the figure, (i) shows the temple in a deployed state, (ii) and (iii) show the temple in a rotated state, and (iv) shows the temple in a stored state. Indicates.

As shown in these figures, the spectacles 1 of the present embodiment has lenses 2 and 2, temples 3 and 3 respectively provided on the left and right of the spectacles, and a front side member to which the temples 3 are connected. 4, 4 and a connecting mechanism 5 for connecting the temple 3 to the wisdom 4. In this embodiment, a rimless frame type spectacle frame having a structure in which the metal tip 4 is directly fixed to the lens 2 is configured.

The temple 3 is made by bending one wire-like member (flexible linear member) into almost two parts, and the upper wire 3a and the lower wire 3a arranged on the upper side in the unfolded state. And a lower wire 3b arranged in Upper wire 3
Both a and the lower wire 3b have appropriate flexibility in the direction orthogonal to the extending direction.

Since the upper wire 3a and the lower wire 3b are connected to each other at their rear ends (temple end side), their relative movement in the stretching direction is restricted. On the other hand, each tip extends to the connecting mechanism 5,
Are separately rotatably connected to the wisdom 4. The configuration of the connecting mechanism 5 will be described later in detail.

The rotation axes of the upper wire 3a and the lower wire 3b are inclined substantially 45 ° inward from the temple 3 in the unfolded state (i) and are substantially horizontal, as shown by the broken line in FIG. Has been. In addition, the upper wire 3a and the lower wire 3b
Since they are connected separately from each other, their rotation axes are arranged substantially vertically in parallel.

In this structure, when a force in the rotational direction is applied to the temple 3 in the expanded state (i), the upper wire 3a,
While the lower wire rods 3b rotate individually, the temple 3 as a whole has its inner surface directed toward the rotation axis (i
It rotates from i) to (iii), and when it rotates about 180 °, the storage state (iv) is reached. Since the tips of the upper wire 3a and the lower wire 3b are connected separately, the upper wire 3a and the lower wire 3b are in a state of intersecting each other in the vicinity of the stored state (iv). It should be noted that although it is rotated in the downward direction in the figure, it can be rotated in the same manner in the upward direction.

The temple 3 has a shape that is curved so as to bulge outward in accordance with the shape of the temporal region of the spectacle user, while the front part of the spectacle 1 also has the shape of the front face of the spectacle user. Together, it has a shape that curves so as to bulge outward. Therefore, as described above, temple 3
In the configuration in which the inner surface of the eyeglasses is rotated while turning the inner surface side toward the rotation axis, the curved direction of the temple 3 and the curved direction of the front portion are aligned in the stored state (iv), so that the eyeglasses 1 in the stored state (iv) are very It becomes compact.

Further, since the temple 3 is composed of a flexible wire-like member and can be operated in the horizontal direction and the vertical direction, the temple 3 itself elastically deforms or rotates even when an external force is applied. Absorbs external force by moving
Can be dispersed and is unlikely to deform or break.

Further, the spectacles (spectacle frame) of the present embodiment exerts the characteristic functions and actions described below based on the above configuration.

FIG. 3 is a diagram schematically showing the operation of the temple 3 of the glasses of this embodiment. In the figure, for simplification of description, a temple 3 is used in which one upper and lower wire rods 3a and 3b are symmetrically bent at an acute angle in the middle of one flexible linear member. Not limited to such a shape, the temple 3 having the shape shown in FIGS. 1 and 2 and the temple 3 of a modified example described later can also exhibit the same functions and actions as those described below.

As shown in the figure, the temple 3 of this embodiment is composed of two flexible wire members, an upper wire 3a and a lower wire 3b. The tip end of the upper wire 3a is rotatably connected about a rotation fulcrum A, and the tip end of the lower wire 3b is rotatably connected about a rotation fulcrum B. Further, the rear end of the upper wire 3a and the rear end of the lower wire 3b are connected at a restriction point C, and the relative movements in the drawing direction are mutually restricted.

According to this structure, when the temple 3 is rotated, the tip ends of the upper wire 3a and the lower wire 3b try to rotate so as to draw different rotation trajectories due to the restraint of the connecting mechanism. On the other hand, on the rear end side of the upper wire 3a and the lower wire 3b, a force that restricts the relative movement of both wires in the extending direction acts.

As a result of the opposing forces acting on the front end side and the rear end side of the upper wire 3a and the lower wire 3b in this way, at least one of the upper wire 3a and the lower wire 3b undergoes bending deformation. That is, the upper wire 3a and the lower wire 3b
And rotate while drawing surfaces of revolution that are dissimilar to each other.

The restoring force of the bending deformation acts in the direction of the straight line (shown by the broken line) connecting the rotation fulcrum of the bent wire and the restriction point C. Then, in this restoring force, in a direction parallel to a plane orthogonal to a straight line (virtual center line of the temple 3; shown by a chain line) connecting the midpoint D of the rotation fulcrums A and B and the regulation point C. The component acts as a force (rotation component force) for voluntarily rotating the temple 3.

Hereinafter, the rotating operation of the temple 3 from the unfolded state (i) to the housed state (iv) will be described in order.

In the expanded state (i), the upper wire 3
Since neither a nor the lower wire 3b is bent and deformed and no restoring force is generated, the rotational component force is zero.

When the temple 3 is rotated counterclockwise (downward) from the unfolded state (i), the distance between the regulation point C and the lower rotation fulcrum B becomes shorter, so that the state (ii) is shown. Thus, the lower wire 3b on the lower side (front side in the rotation direction) is flexibly deformed. At this time, the restoring force of the lower wire 3b acts in the linear direction connecting the rotation fulcrum B and the restriction point C, as indicated by the black arrow. Then, the rotational component force acts in the direction of returning the temple 3 to the expanded state (i) as shown by the white arrow.

Although not shown, when the temple 3 is rotated clockwise from the unfolded state (i), the upper wire 3a is flexibly deformed, so that the temple 3 is also returned to the unfolded state (i). Rotational force acts on.

Therefore, the rotational component force is in the expanded state (i).
In the vicinity of (a range of approximately less than ± 90 ° centered on the deployed state (i)), the temple 3 acts in the direction of rotating toward the deployed state (i).

When the temple 3 is rotated from the expanded state (i) to the position of 90 ° in the upward or downward direction, the acting direction of the restoring force overlaps (becomes parallel to) the virtual center line of the temple 3. , The rotation component force becomes zero.

When the temple 3 is further rotated beyond this state, an angle is created between the acting direction of the restoring force and the virtual center line of the temple 3 as shown in the state (iii), so that the temple 3 is rotated again. Component force acts. However, since the sign of the angle is opposite to that in the state (ii), the action direction of the rotational component force is opposite. That is, the rotational component force acts in the direction of promoting the rotation of the temple 3.

From around this point, the upper wire 3a also begins to bend due to the torque exerted by the restoring force of the lower wire 3b on the restriction point C. The rotational component of the restoring force of the upper wire 3a acts in the opposite direction to the rotational component of the lower wire 3b.

Then, as the temple 3 is rotated, the magnitudes of the rotational component forces of both the wire rods approach each other, and when the temple 3 is rotated about 180 ° from the expanded state (i), both wire rods are rotated. The rotational force components are in perfect balance.
That is, in this state, when viewed as the entire temple 3, the component of the restoring force that acts in the direction of rotating the temple 3 becomes zero. This state is the storage state (iv).

When the temple 3 is rotated counterclockwise from the housed state (iv), the amount of deformation of the upper wire 3a increases and the amount of deformation of the lower wire 3b decreases. Becomes larger, and force acts in the direction of returning the temple 3 to the stored state (iv). Conversely, when the temple 3 is rotated clockwise from the stored state (iv), the lower wire 3b
Rotational component force is larger due to
A force acts in the direction to return the to the stored state (iv).

Therefore, the rotational component force is the stored state (iv).
In the vicinity of (the range of approximately less than ± 90 ° about the stored state (iv)), the temple 3 acts in the direction of rotating toward the stored state (iv).

As described above, according to the configuration of this embodiment, the temple 3 in the rotating state is rotated by its own restoring force toward the deployed state (i) and the stored state (iv), And, it will be stable at the position of that state.

Therefore, the temple 3 can be easily expanded and stored, and the temple 3 can be prevented from rotating in the expanded state (i) and the stored state (iv), which improves the handling and stabilizes the handling. It is possible to improve the quality.

Further, since these actions are exhibited by the bending of the temple itself and its restoring force, it is not necessary to add a spring component or other components, and the structure is simplified,
It is also possible to reduce the number of parts, facilitate the design, and reduce the cost.

Next, the connecting mechanism 5 of the temple 3 will be described in detail with reference to FIG.

FIG. 4A is an enlarged top view of the connecting mechanism 5 of the temple 3, showing the connecting portion in cross section. FIG. 2B is an enlarged perspective view of the connecting mechanism 5 of the temple 3.

As shown in the drawing, the wisdom 4 is provided with two shaft holes 40, 40 for axially supporting the temple 3 vertically separated from each other. The axes of the shaft holes 40, 40 are arranged at an inclination of about 45 ° with respect to the front surface of the spectacles (note that the front surface is a virtual vertical direction in contact with the left and right lenses 2 and 2 of the spectacles). A flat surface.). The axial directions of the two are substantially parallel to each other.

On the other hand, the upper wire 3a and the lower wire 3b of the temple 3 are vertically separated from each other by a width substantially equal to the separation width of the shaft holes 40, 40 and extend to the connecting mechanism 5 in parallel. further,
The tip side of the temple 3 is bent into a crank shape, and the temple 3 is approximately 90 ° with respect to the front surface of the glasses.
The shape of the temple tip 30 is such that the direction of the temple tip 30 exactly overlaps the axis of the shaft hole 40. That is, the angle between the main body of the temple 3 and the temple tip 30 is approximately 45 °.

In this embodiment, the temple 3 is attached to the tip 4 using the connecting pin 50. The connecting pin 50 is a bottomed tubular member made of a resin material or the like, and has a head portion having a diameter sufficiently larger than the shaft hole 40, and a body portion having a diameter slightly smaller than the shaft hole 40.
The retaining portion has a diameter slightly larger than that of the shaft hole 40.

At the time of attachment, first, the connecting pin 50 is fitted into the shaft hole 40. The connecting pin 50 is prevented from coming off by the barb of the coming-off preventing portion. Next, the temple tip 30 is pressed into the hole of the connecting pin 50. At this time, the protrusion 31 provided on the temple tip 30 is fitted into the groove 52 of the hole inner surface 51 of the connecting pin 50 to prevent the temple 3 and the connecting pin 50 from coming off.

By the connecting mechanism 5, the tips of the upper wire 3a and the lower wire 3b of the temple 3 are separately and rotatably connected to the tip 4. Temple 3 at this time
The rotation axis of is inclined inwardly by about 45 ° from the temple 3 and is substantially horizontal.

(Modified Example of Connecting Mechanism) FIG. 5 shows the connecting mechanism 5.
Shows a modified example of.

As shown in the figure, in this example, the wisdom 4 is integrally provided on the frame member 6 of the spectacles. The temple tip 30 is not provided with a protrusion for preventing the temple from coming off. Other configurations are the same as those in FIG.

At the time of attachment, first, the connecting pin 50 is fitted into the shaft hole 40. The connecting pin 50 is prevented from coming off by the barb of the coming-off preventing portion. Next, the temple tip 30 is pressed into the hole of the connecting pin 50. At this time, the temple 3 and the connecting pin 50 are prevented from coming off by adhesively fixing the temple tip 30 to the connecting pin 50.

By the connecting mechanism 5, the tips of the upper wire 3a and the lower wire 3b of the temple 3 are separately rotatably connected to the tip 4.

FIG. 6 also shows a modification of the connecting mechanism 5.

As shown in the figure, in this example, the end portion 20 of the lens 2 is provided so as to form an angle of approximately 135 ° with the front surface. At the end portion 20 of the lens 2, two shaft holes 21 and 21 for axially supporting the temple 3 are provided vertically separated from each other.

As described above, according to the present invention,
The temples can be easily expanded and stored, and the temples can be prevented from rotating in the expanded and stored states, so that the handleability and the stability can be improved.

Further, since these actions are exerted by the bending of the temple itself and its restoring force, it is not necessary to add a spring component and other components, and the structure is simplified,
It is also possible to reduce the number of parts, facilitate the design, and reduce the cost.
