Description

TECHNICAL FIELD The present invention relates to a foldable spectacle frame mainly used for reading glasses, sunglasses, or nearsighted/farsighted spectacles.

Conventionally, when carrying glasses such as reading glasses without removing them, if the glasses are carried in a bag or pocket as they are, there is a risk that the glasses will be damaged, such as the lenses being scratched or the frames being bent. Therefore, the spectacles are generally carried in a spectacle case.

However, when the spectacles are carried in a spectacle case, they are bulky and occupy a large space in a bag or pocket.

By the way, foldable spectacles have already been disclosed so that the spectacles can be made compact when carried.

For example, in Patent Document 1, only the part of the temple (the part of the temple that is hung on the ear of the user such as the wearer) is rotated about 180 degrees in front of the lens from the rear horizontal state, passing below, and this front A configuration is disclosed in which the temple end portion is bent from below from a horizontal state to the rear surface of the lens on the opposite side to the mounting portion, and is held and stopped by the rear surface of the lens and the pad foot portion. That is, Patent Document 1 discloses a configuration in which only the temple portion of the spectacles is folded and fixed.

Also, in Patent Document 2, there are one or two telescoping or fixed bridges (parts that connect the left and right limbs and hang over the nose of the user, such as the wearer), and the hinges and/or Arrangements are disclosed that allow the lens or lens equivalent to fold outward, inward, and/or even upward, with a spring-loaded hinge. That is, Patent Document 2 discloses a configuration in which lenses are folded by hinges provided on a bridge. The "rim" is a frame into which either the left or right lens is put and fitted.

Embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. However, the components described in this embodiment are merely examples, and the scope of the present invention is not limited to them.

<Structure of spectacle frame A>
The spectacle frame A, as shown in FIG. 1, is connected to a pair of rims 1, which are frames into which either the left or right lens is mainly inserted and fitted, and one end of each of the left and right rims 1, and the spectacle frame A is hung. It has a bridge 2 that spans over the nose of a user such as a wearer when worn, and a temple 4 that is connected at one end to the other end of each of the left and right rims 1 via a hinge 3 (an example of a second hinge). .

1 to 6, the lenses fitted to the left and right rims 1 are omitted. Moreover, it is desirable that the thickness of each lens fitted to each of the left and right rims 1 is equal to or less than the thickness of each rim 1 . If the thickness of each lens exceeds the thickness of each rim 1, the lens protrudes from the rim 1 and comes into contact with the other lens and other components such as the temple 4 when the spectacle frame A is folded. , it may be damaged or hinder folding.

Beneath one end side of each of the left and right rims 1 connected to the bridge 2, a nose pad (nose pad) is placed via clings 11 against the nose of the user such as the wearer when the spectacle frame A is hung. 12 are provided respectively. In addition, "Krings" is a member that supports the nose pad. Each nose pad 12 and each corresponding clings 11 are provided so as to be rotatable in the left-right direction with respect to each rim 1 . However, each nose pad 12 and each corresponding clings 11 are desirably configured to be fixable at a position where the nose pad 12 contacts the nose of a user such as a wearer. This is because it is preferable that each nose pad 12 and each corresponding clings 11 should not rotate (fixed) when a user such as a wearer puts on the spectacle frame A. In this embodiment, the configuration in which each nose pad 12 is provided with each corresponding clings 11 is shown, but the present invention is not limited to this configuration. A configuration in which the pad 12 is provided directly below one end side of each rim 1 may be employed.

The bridge 2 mainly has a left member 21 , a right member 22 , and a hinge 23 (an example of a first hinge) connecting the left member 21 and the right member 22 . As described above, the bridge 2 is divided into the left member 21 and the right member 22, and the left member 21 and the right member 22 are connected by the hinge 23, so that the user such as the wearer of the spectacle frame A can By folding the bridge 2 into two in the front-rear direction with the hinge 23 as a fulcrum, the left and right rims 1 are folded into two in the front-rear direction, and the front surfaces or the rear surfaces of the respective rims 1 are joined together. .

Each temple 4 mainly includes a member 41 (an example of a first member) connected to the other end of each rim 1 via a hinge 3, and a member 42 (second member ) and a joint 43 that connects the member 42 to the member 41 so as to be able to rotate downward. Thus, each temple 4 is connected to the member 41 via the joint 43 so that the member 42 can rotate downward. Specifically, as shown in FIG. 5, the member 41 is supported by a shaft 44 provided inside the joint 43 . Further, the member 42 is supported by a shaft 45 provided inside the joint. Therefore, as shown in FIG. 2, the temple 4 rotates the member 42 downward so that the lower side of the member 42 joins the lower side of the member 41 as shown in FIG. It can be folded in two vertically as a fulcrum.

In this embodiment, each temple 4 is connected to the member 41 via the joint 43 so that the member 42 can rotate downward. However, the present invention is not limited to this configuration. Instead, for example, without using the joint 43, the member 42 may be connected to the member 41 so as to be rotatable downward. For example, as shown in FIG. 7, the lower rear end of the member 41 and the lower front end of the member 42 may be connected by a shaft 46 .

Moreover, as shown in FIG. 4 , the height of each temple 4 in the folded state (from the upper side of the member 41 to the upper side of the member 42 ) is substantially the same as the height of each rim 1 . Further, each temple 4 has a width (from one side of the member 41 or member 42 to the joint 43 ) in a folded state that is substantially the same as the width of each rim 1 . That is, the area of one side of each folded temple 4 is substantially the same as the area of the front and rear surfaces of each rim 1 .

A fitting hole 431 into which the nose pad 12 can be fitted is provided at an appropriate location on the outside of the joint 43 . In this embodiment, the fitting hole 431 is provided on the outer surface of the joint 43 near the member 42 (see FIG. 1). However, the position of the fitting hole 431 is not limited to this configuration, and may be provided on the upper surface of the joint 43, for example.

With such a configuration, each temple 4 in a folded state covers and protects the entire rear surface of each rim 1 including the lens fitted therein.

In addition, when the spectacle frame A is folded in this way, each component is in close contact with each other, so that it is resistant to pressure from the surroundings such as being hit by something or being crushed by other luggage in a bag, and is not damaged. .

<Regarding portability of spectacle frame A>
The spectacle frame A can be folded and put in a pocket or bag and carried. As shown in FIGS. It is also possible to carry the spectacle frame A as a necklace by attaching it to a necklace 5 worn around the neck by a user such as a wearer. By adopting such a configuration, the troublesomeness of carrying the spectacle frame A (the spectacle frame A may be forgotten to be put in the bag, and it is troublesome to take out the spectacle frame A from the bag) is reduced. be able to. In particular, it is convenient when the spectacle frame A is used as reading glasses, or when the spectacle frame A is worn only in certain situations, such as when the spectacle frame A is not normally worn, such as when used as sunglasses.

<Method for folding eyeglass frame A>
Next, a method for folding the spectacle frame A will be described. Here, for convenience of explanation, a description will be given of a state in which the spectacle frame A that can be worn by a user such as a wearer is opened, folded, and fastened to the necklace 5 .

First, as shown in FIGS. 2 and 3, each of the left and right rims 1 is folded forward in two with the hinges 23 of the bridge 2 as fulcrums so that the front surfaces of the left and right rims 1 are joined together. .

At the same time, as shown in FIG. 2, the member 42 of each temple 4 is rotated downward with the joint 43 as a fulcrum so that the lower side of the member 42 joins the lower side of the member 41 as shown in FIG. Then, the temple 4 is folded vertically into two.

Moreover, as shown in FIG. 3, the temple is vertically folded in two with the hinge 3 as a fulcrum so that the inner surface of the member 41 faces the rear surface of the rim 1 connected by the hinge 3. Fold 4.

After completing these three steps of "folding the rim 1", "folding the members 41 and 42 of the temple 4", and "folding the member 41 of the temple 4 so as to face the rear surface of the rim 1", the spectacle frame A is completed. is completed, and the spectacle frame A is in a folded state. After that, each nose pad 12 is rotated and fitted into the fitting hole 431 . By rotating the nose pad 12 and fitting it into the fitting hole 431 in this manner, the nose pad 12 is housed. Also, fitting the nose pad 12 into the fitting hole 431 serves as a stopper, and the spectacle frame A is held in a folded state.

Then, as shown in FIGS. 5 and 6, the eyeglass frame A in the folded state is fastened to the necklace 5 using fasteners 51 .

Needless to say, when the spectacle frame A, which is fastened to the necklace 5 and folded, is opened to be in the state of spectacles, the flow is reversed.

Also, in the above description, the flow of "folding the rim 1", "folding the members 41 and 42 of the temple 4", and "folding the member 41 of the temple 4 so as to face the rear surface of the rim 1" was described. This is for convenience of explanation, and is not limited to this flow, and the order is random. Moreover, it is good also as a structure which performs three procedures simultaneously.

<Modification 1>
As described above, the member 42 is pivoted downward so that each temple 4 in the folded state is folded to cover and protect the entire rear surface of each rim 1 including the fitted lens. The area of one side of each temple 4 is approximately the same as the area of the front and rear surfaces of each rim 1 .

However, in this case, the width of each rim 1 determines the length of the members 41 and 42 of each temple 4 . On the other hand, the depth of the face (head) of the user such as the wearer of the spectacle frame A, that is, the length from the front of the user's face to the ear differs from user to user. Therefore, depending on the user, the temple 4 may be too long or too short.

Therefore, the member 41 and/or the member 42 may have a configuration in which a plurality of members having different thicknesses are combined so as to be stretchable in the longitudinal direction of the temple 4 (not shown). With such a configuration, it is possible to adjust the length of the temple 4 by extending and contracting the member 42 of the temple 4 and the like in the state of the spectacles with the spectacle frame A opened, which is convenient.

<Modification 2>
The hinges 3 connecting the other ends of the left and right limbs 1 and the temples 4, the hinges 23 connecting the left and right members 21 and 22 of the bridge 2, and/or the joints 43 connecting the members 41 and 42 of the temple 4 are , it is desirable to be able to stop at a predetermined angle. In this way, the hinges 3 and the like provided on the spectacle frame A are configured so as to be able to stop at a predetermined angle, so that the spectacle frame A can be held in the state of the spectacles opened or folded, and the wearer can The spectacle frame A is not folded or unfolded unintentionally by the user, which is convenient.

In addition, for example, for a configuration in which the hinge 3 or the like can be stopped at a predetermined angle, a ball member protrudes from the upper member at the joint surface between the upper member and the lower member of the hinge 3, and a fitting hole provided in the lower member. When the ball member is fitted in, it can be realized by a configuration in which it is temporarily held (not shown). However, since various configurations are known for the configuration in which the hinge 3 and the like can be stopped at a predetermined angle, detailed description thereof will be omitted.

For example, the hinge 3 is such that the angles formed by the inner surface of the member 41 and the rear surface of the rim 1 are "90°", "85°", "80°", and "75°" when the spectacle frame A is opened. , or "70°", when the spectacle frame A is folded and the inner surface of the member 41 and the rear surface of the rim 1 are joined, the angle formed by the inner surface of the member 41 and the rear surface of the rim 1 is "20°", It is desirable to have a configuration that can be stopped at "15°", "10°", "5°" or "0°".

For example, the hinge 23 is such that the angle formed by the front surface of the left member 21 and the front surface of the right member 22 is "160°", "165°", "170°", or "170°" when the spectacle frame A is open. 180°", the spectacle frame A is folded and the front surfaces of the rims 1 are joined together, the angle formed by the front surface of the left member 21 and the front surface of the right member 22 is "0°", and each can be stopped. Configuration is preferable.

For example, the joint 43 has an angle of "160°", "165°", "170°", or "180°" formed by the lower side of the member 41 and the lower side of the member 42 in the state of the spectacles with the spectacle frame A opened. Then, the spectacle frame A is folded, and in a state in which the lower side of the member 42 is joined to the lower side of the member 41, the angle formed by the lower side of the member 41 and the lower side of the member 42 is "0°", and each can be stopped. is preferable.
