Description

Attachment / detachment mechanism for eyeglass attachment, eyeglass attachment, eyeglasses, and eyeglass system

The present invention relates to a technique for detachably attaching a spectacle attachment to spectacles.

As a result of the miniaturization of electronic components, various devices have become wearable. For example, a head-mounted display has been developed based on a display that was conventionally only a large stationary type, or a head-mounted type that can capture an object in the direction of the user's line of sight based on a camera that was conventionally handheld. A camera has been developed.
A device having such a wearable property as one of its properties (this is not limited to the display and camera described above, and may include various lighting devices such as a light for lighting, a radio, and an audio player, In addition, devices other than electronic devices such as a magnifying glass may also be included in the future, but their application is desired in the future, but how to attach them to the user's body is a problem.
As a result of research, the inventor of the present application has come up with the idea that glasses can be used to attach the above-mentioned device having wearability as one of its properties to the user's body. That is, the present inventor has obtained the idea that it would be convenient if the device as described above could be attached to the user's body via the glasses worn by the user.
Since glasses are used over the user's ears in everyday life, when the device as described above is attached to the glasses, the user's hands are kept free. Even if such a device is attached, the user is in a state where both hands are open, which is convenient for using the above-described device in daily life situations. Glasses are mainly used to correct vision, but even those who do not need vision correction are free to wear Date glasses or sunglasses. Even when using glasses that can be used by everyone in order to attach a device as one of the above to the user's body, the user is not selected.
In that sense, it would be very convenient if various devices, particularly small devices, could be attached to the glasses.
For example, it would be convenient if a small image display device could be attached to spectacles and used as a head-mounted display, or if a small camera could be attached to spectacles and photographed things that would go into my field of view. .
However, a device as described above having wearable properties as one of its properties (Since this device is assumed to be attached to glasses in this application, it is hereinafter referred to as “glasses attachment” in the present application. It is not easy to be able to attach to the glasses.
Difficulties in making it possible to attach the spectacle attachment to the spectacles arise from the variety of spectacle structures. The design of eyeglasses, which are often demanded of fashion, is extremely diverse. Therefore, regardless of whether the spectacle attachment to be attached to the spectacle attachment is used as a dedicated product, the spectacle attachment is attached to general spectacles anywhere on the spectacles. The problem is whether to attach the attachment. For example, since almost all spectacles have a common member called a lens and a temple, it is conceivable to attach an eyeglass attachment to one of them. There are a variety of thickness differences, and the temples have a variety of thickness, cross-sectional shape, etc., so the eyeglass attachment is attached to the glasses via the lens or temple. Is still not easy.
Moreover, the attachment of the spectacle attachment to the spectacles is preferably detachable so that the spectacle attachment can be detached from the spectacles when not in use. It is difficult to develop a mechanism that attaches to the head.
This invention makes it the subject to propose the technique for enabling attachment to the spectacles of spectacles attachment with respect to almost all spectacles.

The inventor of the present application has conducted research in order to solve such problems, and has obtained the following idea.
Almost all spectacles are provided with a member called a hinge (hinge) at a portion connecting the spectacle lens and the temple. Hinge is generally at the outer side edge of both lenses in the case of frameless type glasses, and at the outer side edge of the frame in the case of glasses with frames. In any case, almost all glasses are provided. In many cases, the hinge is attached with a screw that penetrates the hinge vertically. The screw passes through the base end of the temple while being fixed to the hinge, and the temple can rotate with respect to the lens of the spectacles around the screw. In other words, the hinge screw is basically indispensable in order to perform the rotational movement with respect to the temple lens, and is present in almost all hinges except for special hinges.
The inventor of the present application paid attention to this hinge screw. Since the screw attached to the hinge exists in almost all spectacles, if the hinge screw is used when attaching the spectacle attachment to the spectacle, the spectacle attachment is attached to almost all spectacles. Will be installed. In addition, since the screw has an essential function of being fixed by being screwed to something, if the essential function is used, an attachment for spectacles (or spectacles for spectacles) is used. Naturally, it is possible to fix the attachment for spectacles for fixing the attachment and a component interposed between the screws.
In other words, the idea obtained by the present inventor is that it is very reasonable to use the hinge screw when attaching the spectacle attachment to the spectacles in terms of its versatility and its function. It is.
Based on the above idea, the present inventor has made the following invention.
The present invention is broadly classified into a first invention and a second invention as described below.
The first invention is as follows.
The inventor of the present application first proposes as spectacles that are used by attaching to a pair of eyeglasses that are provided with a pair of left and right temple hinges attached with screws that penetrate a part of them in the vertical direction. It is an attachment / detachment mechanism for attaching the attachment.
The attachment / detachment mechanism is configured such that the length of the screw attached to at least one of the hinges is such that its length penetrates the hinge and its tip is exposed from below the hinge. A first member fixed to an exposed portion which is a portion exposed from below the number, and a second member attached to the spectacle attachment and detachably attachable to the first member. Yes.
Conventionally, the screws attached to the hinge are inserted into the vertical holes threaded inside the hinge, and the upper side (note that the concept of up / down, front / rear, left / right in this application is that the user wears glasses. When the face is faced to the front, the user's top, bottom, front, back, left, and right directions should be matched.) It is usually made flush. Since such a screw has no portion exposed from the hinge, it cannot be used for mounting the first member.
Therefore, in the present application, the length of the screw is set so that the screw inserted into the hinge hole from the upper side penetrates the hinge and its tip is exposed from below the hinge. When such a screw is screwed into the hinge, the tip of the screw is exposed from below the hinge. In the present invention, an exposed portion corresponding to a portion exposed from below the hinge of the screw is used, and the first member is fixed thereto. Since the first member can be detachably fixed to the second member provided on the spectacle attachment, the spectacle attachment can be detachably attached to the spectacles to which the first member is attached. That is why.
The advantages of the first invention are as follows.
First, there is an advantage that the first member can be attached to the spectacles only by lengthening the hinge screw included in almost all spectacles. Moreover, the modification of lengthening the hinge screw is very simple, so the technical difficulty is low and the cost is advantageous. In addition, since the modification can be performed on the existing glasses, the first member can be attached to the existing glasses. Therefore, the user can attach the glasses attachment even with the glasses already owned by the user. The glasses can be improved.
The present invention also has an advantage that the first member can be made smaller by dividing the member for detachably attaching the spectacle attachment to the spectacles into the first member and the second member. By dividing the member for detachably attaching the spectacle attachment to the spectacles into the first member and the second member, it is sufficient to allocate a minimum of functions required for the attaching / detaching mechanism to the first member. Therefore, the first member can be made smaller. The first member is basically permanently fixed to the glasses. However, in the case of eyeglasses that often require fashionability as described above, it is expected that there are users who have an aversion to attaching the first member to the eyeglasses if the first member is highly conspicuous. Because of such circumstances, the above-described advantage that the first member can be made small has a great significance.
The first member can be attached to both of the two screws provided on each of the two hinges, or can be attached to only one of the two screws. If necessary, one or two first members may be attached to the glasses. It should be noted that the screw on which the first member is not attached may have the same length as the conventional one. The tip of the screw in this case is flush with the lower surface of the hinge as in the conventional case.
The first member may be attached to the screw in any way as long as the exposed portion of the screw is used.
For example, the first member can be attached to the screw as follows.
For example, the first member includes a plate-like through plate having a through hole through which the exposed portion of the screw penetrates, and the through hole is screwed on an inner peripheral surface of the first member so as to be screwable with the screw. A structure is employed in which the first member is fixed to the exposed portion of the screw by screwing the screw into the through hole while passing through the through hole. Can do. In this case, the exposed portion of the screw is screwed with the through plate included in the first member by utilizing the function of being able to screw with something that the screw has.
Alternatively, the first member includes a plate-like through plate provided with a through hole through which the exposed portion of the screw passes, and the first member exposes the screw through the through hole. It is possible to adopt a structure in which the through plate is sandwiched between the upper surface of the nut screwed to the portion and the lower surface of the hinge so as to be fixed to the exposed portion of the screw. In this case, the inner periphery of the through hole need not be threaded. In this case, the exposed portion of the screw is screwed with the nut by utilizing the function of being able to screw with something that the screw has. Employing this structure has an advantage that the first member can be fixed to the screw even if the screw diameter is different. Although the screw screwed to the hinge may differ depending on the spectacles, in this structure, the first member can be fixed to the screw only by preparing a nut matched to the screw. The nut does not necessarily have to penetrate through the hole in the nut thickness direction. For example, a structure that does not penetrate the hole, such as a cap nut, may be employed.
In the case of adopting a structure in which the first member is fixed to the screw using a nut, the following structure can be further employed. In the structure, the through hole is sized and shaped so that a gap is formed between the through hole and the screw, and the nut includes a nut portion that enters the gap and the gap. A flange portion having a size and shape not to enter, and the nut portion inserted into the through hole is screwed into the exposed portion of the screw, and the flange portion The first member is fixed to the exposed portion of the screw by sandwiching the through plate between the upper surface of the part and the lower surface of the hinge. The nut used in this case is also called a flanged nut, but the first member can be attached to the screw even if such a nut is used. In addition, the hole of a nut part does not need to penetrate the flange part.
When using a nut having a flange portion as described above, which is also called a flanged nut, the flange portion can have a size and shape that does not enter the gap and can be easily picked by a user with a finger, By doing so, it is possible to allow the user to attach and detach the nut and the first member with respect to the screw by rotating the flange portion picked by a finger in an arbitrary direction. As described above, the first member is basically permanently attached to the glasses, but if such a structure is adopted, the first member can be attached to and detached from the glasses. As described above, the second member and the eyeglass attachment including the second member can be freely attached to and detached from the first member and the eyeglass including the second member as necessary. However, when the first member is no longer necessary for a certain period of time, such as when the eyeglass attachment is no longer used in combination with the eyeglass, or the first member is attached to the eyeglass although it is small. For users who are concerned about this, it is considered that the configuration in which the first member can be removed from the glasses is beneficial. However, this advantage is not achieved for the first time by using the nut having the flange portion as described above, and the first member is detachably fixed to the exposed portion of the screw. If so, it can also be obtained by other structures.
If the first member is detachably fixed to the hinge screw, the first member and the second member do not necessarily have to be detachable. If the first member is detachably fixed to the hinge screw, when the spectacle attachment is removed from the spectacles, the first member and the second member are removed by removing the first member from the spectacle screws. This is because the eyeglass attachment and the eyeglass attachment need only be removed from the eyeglasses. If the fixing of the first member and the second member is not detachable, the first member does not necessarily need to be small, and the first member and the second member can be integrated.
As described above, the first member should be as small as possible mainly for fashion reasons. Moreover, since it is attached to spectacles (and it is highly likely to be attached permanently), it is preferably lightweight.
If a fashion side is considered more, it is preferable that the 1st member is settled in the part pinched | interposed into both the temples of the said spectacles when the said spectacles are planarly viewed. If the first member fits in the portion sandwiched between the temples of the glasses, even if the user wears the glasses with the first member attached, behind the frame or wisdom if there is a lens or In addition, since the first member is located behind the temple when viewed from the side of the user wearing the glasses, there is a high possibility that the presence of the first member will not be taken by a third party. .
The first member is preferably within a range close to the temple, for example, within 10 mm, preferably within 6 mm from the temple. This is because such a first member is not conspicuous, and even when the user wears glasses with the first member attached to a screw, it is difficult to interfere with the user's face. More preferably, the first member is positioned behind the wisdom of the glasses when the glasses are viewed from the front. If it does in this way, the presence of the 1st member will become more unpretentious from a third party. The first member may be located at a position ahead of the screw when the glasses are viewed from the side. This is also useful for making the presence of the first member more unpretentious from a third party. Moreover, it is preferable that the first member be within the range of the height in the vertical direction of the eyeglass lens. This is also useful for making the presence of the first member more unpretentious from a third party.
The detachable fixing of the first member and the second member may be realized by any configuration.
For example, the first member and the second member can be detachably fixed by a detachable ball joint. In this case, one of the first member and the second member is provided with a ball for forming a ball joint, and the other member having a concave surface for storing the ball is provided on the other of the first member and the second member.
Alternatively, the first member includes a cylinder that is substantially parallel to the screw and has an opening at least at an upper end thereof, and the second member includes a rod that can be inserted into the cylinder from the lower end thereof, and the rod A connecting member for connecting the upper end of the eyeglass and the attachment for spectacles, and the second member inserts the rod into the tube from the lower end thereof, and a part of the connecting member is connected to the upper end of the tube. It is possible to adopt a structure in which it is attached to the first member by being locked around the opening. In this case, the second member is attached to the first member due to the weight of the second member and the spectacle attachment. The first member is substantially parallel to the screw, has an opening at least at an upper end thereof, and includes a cylinder having a locking portion at an inner lower side thereof, and the second member extends from the lower end thereof. The second member has a rod that can be inserted into the cylinder, and the second member is inserted into the cylinder from the lower end thereof, and the distal end of the second member is engaged with the engagement portion, whereby the first member is It is also possible to adopt a structure that can be attached. Also in this case, the second member is attached to the first member due to the weight of the second member and the eyeglass attachment. The locking portion in this case can be, for example, a lid or a bottom provided at the lower end of the cylinder.
The above-described structure using the tube and the rod can reverse the relationship of the tube and the rod to the first member and the second member. For example, in the former case, the first member includes a rod that extends in a substantially vertical direction, and a connecting member that connects a lower end of the rod and the through plate, and the second member includes at least A cylinder having an opening at its lower end; and the second member inserts the rod into the cylinder from its upper end, and engages the periphery of the opening at the lower end of the cylinder with a part of the connecting member. By stopping, the structure can be changed to be attached to the first member. In the latter case, the first member is provided with a rod extending in a substantially vertical direction, and the second member is provided with an opening at least at the upper end thereof and a cylinder provided with a locking portion below the inside thereof. The second member is adapted to be attached to the first member by inserting the rod into the cylinder from the lower end thereof and engaging the distal end thereof with the engaging portion. The structure can be changed.
In the structure using the cylinder and the rod described above, the rod is inserted into the opening at the upper end of the tube from its lower end, but it is also possible to insert the rod into the opening at the lower end of the tube from its upper end. In this case, however, it is necessary to prevent the rod from coming off from the cylinder. For example, the first member includes a cylinder that is substantially parallel to the screw and has an opening at least at a lower end thereof, and the second member includes a rod that can be inserted into the cylinder from the upper end thereof. At least one of the cylinder and the rod is provided with a retaining mechanism for detachably fixing the rod to the cylinder in a state where the rod is inserted into the cylinder from its upper end. A structure can be adopted in which the rod is attached to the first member by the function of the retaining mechanism in a state where the rod is inserted into the cylinder from the upper end thereof. Even in this case, the relationship between the first member and the second member of the cylinder and the rod can be reversed. When the relationship between the cylinder and the rod is reversed, the first member is provided with a rod extending in a substantially vertical direction, and the second member is provided with an opening at least at the lower end thereof, and the rod can be received from the upper end thereof. And at least one of the cylinder and the rod is provided with a retaining mechanism for detachably fixing the rod to the cylinder in a state where the rod is inserted into the cylinder from the upper end thereof, The second member is structured to be attached to the first member by the function of the retaining mechanism in a state where the rod is inserted into the cylinder from the upper end thereof.
The retaining mechanism in these cases may have any structure as long as the rod can be prevented from falling out of the tube and, if necessary, the rod can be removed from the tube. For example, the cylinder is a cylinder and includes a notch communicating with the space inside the cylinder, and a part of the cylinder enters the space inside the cylinder via the notch on the outer periphery of the cylinder. A ring spring, which is a ring-shaped spring, is fitted, and the rod is a cylinder having substantially the same diameter as the space inside the tube, and corresponds to the notch when the rod is inserted into the tube. A groove is provided in a predetermined portion, and when the rod is inserted into the cylinder, the ring spring entering the space inside the cylinder is fitted into the groove so that the rod is inserted into the cylinder. The rod can be fixed to the cylinder by applying a downward force to the rod and removing the ring spring from the groove against the elastic force of the ring spring. To Gubane and said groove, said rod being adapted to be caused to function as a retaining mechanism for removably secured to the barrel, it is possible to adopt a structure called.
Alternatively, a magnet can be used to detachably fix the first member and the second member. For example, one of the first member and the second member is a first magnet that is a magnet, and the other of the first member and the second member is a second magnet that is a magnet that adsorbs to the first magnet or A magnetic material that adsorbs to the first magnet; and a first magnet provided on one of the first member and the second member; and provided on the other of the first member and the second member. Further, it is possible to adopt a structure in which the first member can be detachably attached to the second member by adsorbing the second magnet or the magnetic material. Otherwise, instead of this, the first member is provided with a rod-like rod-like body that is substantially parallel to the screw, and the second member is opposed to each other with an interval by the length of the rod-like body. An opposing member, wherein the first magnet is provided at one of both ends of the rod-like body and the opposing member, and the second magnet or magnetic material is provided at the other of both ends of the rod-like body and the opposing member. It is also possible to adopt a structure that is provided.
The inventor of the present application also combines eyeglasses having a pair of left and right temple mounting hinges attached with screws that penetrate a part of the eyeglass in the vertical direction, and an eyeglass attachment used by attaching to the eyeglasses. An eyeglass for constituting the eyeglass system is proposed as one aspect of the first invention. Also according to this invention, the same effect as that of the attachment / detachment mechanism of the first invention can be obtained.
The spectacles have a length that extends through the hinge and is long enough to expose the tip of the hinge from below the hinge, below the hinge of the screw attached to at least one of the hinges. A first member fixed to an exposed portion that is an exposed portion is provided, and the first member can be detachably attached to a second member attached to the eyeglass attachment.
The first member of the glasses can be the same as that used for the glasses in the attaching / detaching mechanism of the first invention.
The inventor of the present application also combines eyeglasses provided with a pair of left and right temple hinges attached with screws that penetrate a part of the eyeglass in the vertical direction, and an eyeglass attachment used for attaching to the eyeglasses. An eyeglass attachment for constituting an eyeglass system is proposed as one aspect of the first invention. Also according to this invention, the same effect as that of the attachment / detachment mechanism of the first invention can be obtained.
The spectacle attachment includes a second member, and the second member has a length that is long enough to penetrate the hinge and have a tip exposed from below the hinge. The screw attached to at least one of the screws can be detachably attached to a first member fixed to an exposed portion that is a portion exposed from below the hinge.
The second member of the spectacle attachment can be the same as that used for the spectacle attachment in the attachment / detachment mechanism of the first invention.
The inventor of the present application also combines eyeglasses provided with a pair of left and right temple hinges attached with screws that penetrate a part of the eyeglass in the vertical direction, and an eyeglass attachment used for attaching to the eyeglasses. An eyeglass system is proposed as one aspect of the first invention. Also according to this invention, the same effect as that of the attachment / detachment mechanism of the first invention can be obtained.
The eyeglasses included in the eyeglass system have a length of the screw attached to at least one of the hinges, the length of which extends through the hinge and the tip is exposed from below the hinge, A first member fixed to an exposed portion which is a portion exposed from below the hinge; and the spectacle attachment included in the spectacle system is detachably attachable to the first member. Two members are provided.
The first member and the second member included in this spectacle system can be the same as the first member and the second member in the attachment / detachment mechanism of the first invention.
The inventor of the present application is also an existing spectacle having a pair of left and right hinges to which a screw is attached that penetrates a part of the hinge in the vertical direction, the lower end of the screw being substantially the same as the lower surface of the hinge As one aspect of the first aspect of the present invention, a method of processing the same surface into spectacles for constituting a spectacle system comprising a combination of spectacles and a spectacle attachment used attached to the spectacles is proposed.
In the method, at least one of the screws is replaced with a long screw whose length penetrates the hinge and whose tip is exposed from below the hinge; In the processing method, a first member that is detachably attachable to a second member attached to the spectacle attachment is attached to an exposed portion that is an exposed portion from below the hinge. By doing in this way, the existing spectacles can be processed into the spectacles of the first invention.
Next, the second invention of the present application will be described.
The second invention is not significantly different from the first invention. Similarly to the first invention, the second invention can obtain the same benefits as the first invention by utilizing the exposed portion of the screw.
As described above, in the first invention, the first member is basically permanently fixed to the hinge screw (exposed portion thereof), but the first member is detachable from the screw. It has been described that the first member in this case is not necessarily detachable from the second member.
Briefly speaking, the second invention refers to the first member and the second member that are not removable and collectively referred to as a third member, and the third member attached to the spectacle attachment. Corresponds to a screw that can be detachably attached to the exposed portion of the screw.
As a second invention, the inventor of the present application attaches an eyeglass attachment that is used by attaching to the eyeglasses to a pair of left and right eyeglasses for attaching a temple to which a screw that penetrates a part of the temple in the longitudinal direction is attached. An attachment / detachment mechanism for the screw attached to at least one of the hinges, the length of which extends through the hinge and the tip of the hinge is exposed from below the hinge, The present invention proposes a device including a third member attached to the eyeglass attachment, which is detachable from an exposed portion which is a portion exposed from below the hinge.
Similar to the first invention, this attachment / detachment mechanism has the advantage that the spectacle attachment provided with the third member can be attached to the spectacles only by lengthening the hinge screw included in almost all spectacles. This means that a minimum modification such as screw replacement is required to apply the attaching / detaching mechanism of the second invention to the existing glasses. However, since the attachment / detachment mechanism of the second invention uses a third member in which the first member and the second member are integrated, it is difficult to reduce the size of the third member. However, in the second invention, when the eyeglass attachment is removed from the eyeglasses, the third member is also removed together with the eyeglass attachments, so the size of the third member is not a problem for the user.
The structure for making the third member of the attachment / detachment mechanism of the second invention detachable with respect to the exposed portion of the screw is similar to the structure of the first member and the screw in the case of the first invention. Also good. For example, the third member may include a plate-like through plate having a through hole that penetrates the exposed portion of the screw. In that case, the third member has the through hole penetrated. The nut is fixed to the exposed portion of the screw by sandwiching the through plate between an upper surface of a nut screwed into the exposed portion of the screw and a lower surface of the hinge, and the nut May be shaped so that the user can easily attach and detach the screw.
In the above case where a nut is used, the through hole is sized and shaped so that a gap is generated between the through hole and the screw, and the nut enters the gap. A nut portion and a flange portion having a size and shape not to enter the gap may be provided. In this case, by sandwiching the through plate between the upper surface of the flange portion and the lower surface of the hinge in a state where the nut portion inserted into the through hole is screwed into the exposed portion of the screw, The third member is fixed to the exposed portion of the screw. This invention corresponds to the case of using the flanged nut in the first invention.
When a so-called flanged nut is used, the flange portion has a size and shape that does not enter the gap and can be easily picked by a user with a finger. By rotating in the direction, the user can attach and detach the third member with respect to the screw.
The inventor of the present application combines spectacles having a pair of left and right temple-attached hinges attached with a screw that penetrates a part of the spectacles in the vertical direction, and an spectacle attachment used by attaching to the spectacles. Glasses for configuring the system are proposed as one aspect of the second invention. The same effect as that of the second invention can be obtained with the glasses.
The glasses are exposed such that the length of at least one of the screws is long enough to pass through the hinge and its tip is exposed from below the hinge, and exposed from below the hinge. A third member attached to the spectacles attachment is detachably attached to the exposed portion.
There is no substantial difference between the configuration of the glasses of the second invention and the glasses of the first invention. The glasses of the second invention can be the same as the glasses of the first invention, and the third member attached to the eyeglass attachment used in combination with the glasses of the second invention is the detachable of the second invention. It can be the same as the third member in the mechanism.
The inventor of the present application also combines eyeglasses having a pair of left and right temple mounting hinges attached with screws that penetrate a part of the eyeglass in the vertical direction, and an eyeglass attachment used by attaching to the eyeglasses. An eyeglass attachment for constructing the eyeglass system is proposed as one aspect of the second invention. Also according to this invention, the same effect as the attachment / detachment mechanism of the second invention can be obtained.
The spectacle attachment includes a third member attached to the spectacle attachment, and the third member has a length that penetrates the hinge and a tip that is exposed from below the hinge. The screw attached to at least one of the hinges can be detachably attached to an exposed portion which is a portion exposed from below the hinge.
In addition, the 3rd member attached to the spectacles attachment of 2nd invention can be made into the same thing as the 3rd member in the attachment / detachment mechanism of 2nd invention.
The inventor of the present application also combines eyeglasses having a pair of left and right temple mounting hinges attached with screws that penetrate a part of the eyeglass in the vertical direction, and an eyeglass attachment used by attaching to the eyeglasses. An eyeglass system is proposed as one aspect of the second invention. Also according to this invention, the same effect as the attachment / detachment mechanism of the second invention can be obtained.
In this spectacle system, the length of at least one of the screws included in the spectacles is so long that the hinge penetrates the hinge and its tip is exposed from below the hinge. The eyeglass attachment includes a third member that can be detachably attached to the exposed portion.
The eyeglasses and the third member of the eyeglass system of the second invention can be the same as the eyeglasses and the third member described in the second invention, respectively.
The inventor of the present application is also an existing spectacle having a pair of left and right hinges to which a screw is attached that penetrates a part of the hinge in the vertical direction, the lower end of the screw being substantially the same as the lower surface of the hinge As one aspect of the second aspect of the present invention, a method of processing the same surface into spectacles for constituting a spectacle system comprising a pair of spectacles and a spectacle attachment used by being attached to the spectacles is proposed.
In the method, at least one of the screws is replaced with a long screw whose length penetrates the hinge and whose tip is exposed from below the hinge; In the processing method, the third member attached to the eyeglass attachment can be detachably attached to an exposed portion which is a portion exposed from below the hinge. By doing in this way, the existing spectacles can be easily processed into the spectacles of the second invention.

<< First Embodiment >>
The first embodiment will be described with reference to FIGS.
1st Embodiment is related with the spectacles system which combines spectacles and the attachment for spectacles attached to spectacles. Since the spectacles attachment of the first embodiment is a small display, the spectacles attached with the spectacles attachment function as a head-mounted display.
As will be described later, a first member is attached to the spectacles, a second member is attached to the spectacle attachment, and the first member and the second member are detachable.
First, a method for attaching the first member to the glasses will be described with reference to FIGS.
1a and 1b are side views showing a method of attaching a first member to spectacles included in the spectacle system of this embodiment. (A) to (C) of FIG. 1 a show a state where the right temple 110 and the vicinity of the root thereof are viewed from between the temples 110 of the glasses 100. FIG. 1b is an enlarged view showing a portion surrounded by a broken line in FIG. 1a.
The structure of the glasses 100 shown in FIGS. 1a and 1b will be schematically described.
The glasses 100 are very common glasses. The glasses 100 may be commercially available glasses. The following description will be given on the assumption that the glasses are already sold and are existing glasses owned by the user, but they may be new before sale.
The eyeglasses 100 have a substantially symmetrical structure except for a slight difference such as the temple 110. As described above, the glasses 100 include the temple 110. The eyeglasses 100 include a hinge 120.
In this embodiment, the hinge 120 includes two hinge plates 121 arranged at a predetermined interval so as to be substantially horizontal. The two hinge plates 121 are connected to the wisdom 130 of the glasses 100. Although the wi 130 and the hinge plate 121 may be formed as a single member, in this embodiment, the hinge plate 121 is a separate member from the wi 130, and an appropriate method such as brazing is applied to the wi 130. It is fixed with. Both of the two hinge plates 121 are provided with

circular holes

122 and 122. The two holes 122 have the same diameter, and their axes are positioned on a straight line. Of the inner peripheral surfaces of the two holes 122, at least the inner peripheral surface of the hole 122 formed in the hinge plate 121 located on the lower side is threaded. The upper portion of the hole 122 formed in the upper hinge plate 121 has a large diameter. The screw head is housed in the large-diameter portion of the hole 122 formed in the upper hinge plate 121 when a screw to be described later is screwed.
A temple plate 111 connected to the temple 110 is sandwiched between the two hinge plates 121 arranged in parallel. The thickness of the temple plate 111 substantially matches the width of the gap between the two hinge plates 121. The temple plate 111 may be integrated with the temple 110, but in this embodiment, it is a separate member from the temple 110 and is connected to the temple 110 by an appropriate method such as brazing. A hole 112 is formed in the temple plate 111. The hole 112 has substantially the same diameter as the hole 122 formed in the two hinge plates 121, but the inner peripheral surface thereof is not threaded.
The temple 110 is connected to the hinge 120 by a screw 140 that penetrates the two holes 122 provided in the two hinge plates 121 and the temple plate 111 inserted between the two hinge plates 121 together. It is pivotally fixed. The screw 140 includes a screwing portion 141 threaded on the outer periphery thereof and a head 142 provided at one end of the screwing portion 141, and is screwed into at least the hole 122 of the lower hinge plate 121. (If the screw is also cut inside the hole 122 of the upper hinge plate 121, the screw 140 is also screwed into the hole 122 of the upper hinge plate 121). If the tightening condition of the screw 140 is appropriately adjusted, the temple plate 111 of the temple 110 is fixed to the hinge 120 in a state where an appropriate frictional resistance is applied from the upper and lower hinge plates 121. In this state, the temple 110 can be rotated around the screw 140 penetrating the temple plate 111.
FIG. 1A shows that the normal screw 140A originally screwed to the hinge 120 of the user's glasses 100 is removed from the hinge 120, and a longer screw 140B is screwed to the hinge 120. ing. The screw 140 A originally screwed to the hinge 120 is substantially flush with the lower surface of the lower hinge plate 121 when the screw 140 A is screwed to the hinge 120. It is such a length. On the other hand, the length of the screw 140 B that is newly screwed into the hinge 120 of the user's glasses 100 is such that the tip of the screwing portion 141 is exposed below the hinge 120 when screwed into the hinge 120. It has been long enough to do. Of the threaded portion 141 of the screw 140B attached to the hinge 120, the portion protruding further downward from the lower surface of the lower hinge plate 121 corresponds to the exposed portion in the present invention, but its length is several mm, For example, about 2 to 7 mm is sufficient.
In this embodiment, both the screws 140A attached to the left and right hinges 120 are replaced with the screws 140B due to the necessity due to the relationship with the eyeglass attachment.
If the eyeglasses 100 are new, the screw 140B may be a long screw 140B from the beginning. In this case, whether only one of the screws 140 is the long screw 140B or both of the screws 140 is the long screw 140B may be determined according to the relationship with the spectacles attachment.
The structure of the other part of the glasses 100 is not different from the structure of general glasses. Although not shown in FIGS. 1a and 1b, the eyeglasses 100 include left and right lenses. The left and right lenses may be either transparent or colored, transparent or colorless and transparent. Although the left and right lenses are not shown in FIGS. 1a and 1b, they are surrounded by frames. The above-described wisdom 130 is connected to the outer portions of the left and right frames. A nose pad is provided inside the frame, and the left and right frames are connected by a bridge. However, the eyeglasses 100 may be frameless eyeglasses, or the frame may be provided along only a part of the lens. Furthermore, the lens may be a single lens that is not divided into left and right.
In short, the eyeglasses used in the present invention need only include a hinge 120 to which the temple 110 is connected by the screw 140, and any other structure is adopted. I do not care.
FIG. 1 a (B) shows the spectacles 100 after the screws 140 A are replaced with long screws 140 B.
Next, the first member 200 shown in FIG. 1 a (B) is attached to the exposed portion of the screw 140 B of the glasses 100. The first member 200 is not necessarily limited to this, but is made of resin in this embodiment and is manufactured by integral molding.
The first member 200 includes a cylindrical tube 210. The cylinder 210 is open at both upper and lower ends.
A plate-like connection plate 220 is attached to the outer peripheral surface of the cylinder 210. The connection plate 220 has a hole 221 through which the screw 140B can be passed. In this embodiment, the hole 221 is circular, although not necessarily limited thereto, and the diameter thereof is substantially the same as the diameter of the screw 140B. The diameter of the hole 221 may be larger than the diameter of the screw 140B. The diameter of the hole 221 can be made larger than the diameter of a screw normally used for a hinge of a general spectacle, but in that case, one kind of first member 200 can correspond to almost all spectacles 100. It will be possible.
The first member 200 is fixed to the screw 140B in a state where the exposed portion of the screw 140B is passed through the hole 221. The first member 200 is fixed to the screw 140B using the nut 300. In this embodiment, the nut 300 is a very general hexagon nut, and is made of, for example, metal or resin. The inner peripheral surface of the nut 300 is threaded so that it can be screwed onto the outer peripheral surface of the screw 140B. When the nut 300 is screwed into the tip of the screwing portion 141 of the screw 140B and further tightened as it is while the exposed portion of the screw 140B of the first member 200 is passed through the hole 221, the connecting plate 220 becomes the lower hinge plate. It is sandwiched between the lower surface of 121 and the upper surface of the nut 300. Thereby, the first member 200 is fixed to the screw 140B. The size and shape of the hole 221 are set so as not to prevent the connection plate 220 from being held between the lower surface of the lower hinge plate 121 and the upper surface of the nut 300. A state in which the first member 200 is fixed to the screw 140B is shown in FIG.
Note that the cylinder 210 is substantially vertical in a state where the first member 200 is attached to the screw 140B. The hinge plate 121 included in the hinge 120 may be not horizontal. When the hinge 120 is such, the angle between the connection plate 220 and the tube 210 is designed appropriately (or the angle between the connection plate 220 and the tube 210 is made variable and adjusted appropriately. Thus, the tube 210 with the first member 200 attached to the screw 140B can be kept substantially vertical.
As shown in FIG. 5, the first member 200 fixed to the screw 140 B fits in a portion sandwiched between both temples 110 when the glasses are viewed in plan. More specifically, the first member 200 falls within a range of 6 mm from the temple 110, and is positioned behind the wisdom 130 of the glasses 100 when the glasses 100 are viewed from the front. The first member 200 is also positioned forward of the screw 140B when the spectacles 100 are viewed from the side, and the vertical height of the first member 200 is the vertical direction of the lens of the spectacles 100. It is designed to be within the height range.
In this embodiment, the first member 200 is attached to both the left and right screws 140B.
In this embodiment, it is assumed that the inner peripheral surface of the hole 221 of the connection plate 220 is not threaded, but the inner peripheral surface of the hole 221 is threaded to enable screwing with the screw 140B. It does not matter if it is made. Then, when the screw 140B is screwed to the hinge 120, the screw 140B can be screwed together to the connection plate 220 whose upper surface is in contact with the lower surface of the lower hinge plate 121. . In this way, the first member 200 can be fixed to the screw 140B without using the nut 300.
The first member 200 is attached with a second member 500 attached to an eyeglass attachment 400 that is a display.
The structure of the 2nd member 500 is demonstrated based on FIG. 2 and FIG.
The second member 500 is not necessarily limited to this, but is entirely made of resin in this embodiment.
The second member 500 includes a connecting rod 510 configured in a cylindrical shape. The connecting rod 510 connects the second member 500 to the spectacle attachment 400, and one end thereof is connected to the spectacle attachment 400. The connecting rod 510 is connected to a connection body 520 having a substantially rectangular parallelepiped shape at the other end. The connection between the connecting rod 510 and the connecting member 520 is such that the angle of the connecting rod 510 with respect to the connecting member 520 is variable. Although the connection of the connecting rod 510 to the connecting body 520 may be such that a three-dimensional angle change such as a ball joint is allowed, in this embodiment, the connecting rod 510 is connected to the connecting body 520. Only rotation in the horizontal direction around the connecting portion with the body 520 is allowed.
One end of a crank member 530 formed by connecting a plate-like member into a crank shape is connected to the connection body 520. The crank member 530 does not necessarily have a crank shape, but when the second member 500 is attached to the first member 200, the temple 110, the wisdom 130 or the lens (and the frame) of the glasses 100 is attached. Although not restricted to this, it is set as the shape which can straddle from the top in this embodiment. The connection between the crank member 530 and the connection body 520 is made such that the angle of the crank member 530 with respect to the connection body 520 is variable. This connection may be such that a three-dimensional angle change such as a ball joint is allowed, but in this embodiment, the crank member 530 provides a connection portion between the connection body 520 and the connection body 520. Only rotation in the horizontal direction around the center is allowed.
A rod 540 having a cylindrical shape in this embodiment is connected to the other end of the crank member 530. The cross-sectional shape of the rod 540 is made to match the cross-sectional shape of the internal space of the cylinder 210 provided in the first member 200. The rod 540 is not necessarily limited to this, but is fixed to the crank member 530 so as to be rotatable about its axis.
The second member 500 is attached to the first member 200 by inserting the rod 540 of the second member 500 into the cylinder 210 of the first member 200. When such insertion is performed, the crank member 530 of the second member 500 interferes with the upper end of the cylinder 210 of the first member 200, and the crank member 530 is locked to the cylinder 210. In this state, the second member 500 is fixed to the first member 200. Since the rod 540 is stored in the space inside the cylinder 210 without a gap, the mounting state of the second member 500 to the first member 200 is stable.
The attachment of the second member 500 to the first member 200 may be performed by providing a locking portion that locks the tip of the rod 540 inserted into the cylinder 210 inside the cylinder 210. . The locking portion can be, for example, a bottom provided at the lower end of the tube 210. When the length of the rod 540 is longer than that of the tube 210, the tip of the rod 540 comes into contact with and is locked to the bottom of the tube 210. In this way, the second member 500 may be fixed to the first member 200.
The configuration of the eyeglass attachment 400 will be described with reference to FIG.
The eyeglass attachment 400 is a display, and has a shape as shown in the front view of FIG. 4A, the plan view of FIG. 4B, and the rear view of FIG.
The spectacle attachment 400 includes a case 410 made of resin, for example. The second member 500 described above is connected to the back surface of the case 410. Two second members 500 are provided symmetrically.
Although not shown in the inside of the case 410, a small display device (for example, a liquid crystal display device), a control circuit for displaying an image on the display device, and a control circuit for displaying an image on the display device For example, an interface for acquiring image data from the outside of the spectacle attachment 400 by radio is provided. The image light of the image displayed on the display device is enlarged by a lens (not shown) and projected onto the user's eyes, so that the user can see the image displayed on the display device as a large image. . In this embodiment, a pair of display device and lens is provided for each of the left and right eyes. Image light from the two display devices is projected onto the left and right eyes of the user from two openings 411 provided on the back surface of the case 410.
FIG. 5 shows an overall view of the spectacles 100 and the spectacle attachment 400 when the two second members 500 are attached to the two first members 200 as shown in FIG.
As shown in FIG. 5, when the spectacle attachment 400 is attached to the spectacles 100, the spectacle attachment 400 is positioned immediately before the lens of the spectacles 100. The position and angle of the spectacle attachment 400 can be adjusted by adjusting the angles of the connecting rod 510 and the crank member 530 with respect to the connecting body 520. At this time, the left and right openings 411 on the back surface of the case 410 of the spectacle attachment 400 are respectively positioned in front of the left and right eyes of the user wearing the spectacles to which the spectacle attachment 400 is attached. The spectacles 100 to which the spectacle attachment 400 is attached functions in the same manner as a head-mounted display, and the user can view an image while wearing the spectacles 100.
When the user stops using the spectacle attachment 400, the user lifts the spectacle attachment 400 by the length of the bar 540. Then, the rod 540 is removed from the tube 210, and the first member 200 and the second member 500 are fixed, and the glasses 100 and the eyeglass attachment 400 are fixed.
<Modification 1>
The eyeglass system of the modification 1 is demonstrated using FIG.
The eyeglass system of Modification 1 is substantially the same as the eyeglass system of the first embodiment.
As in the case of the first embodiment, the eyeglass system of Modification 1 includes the eyeglasses 100, the first member 200 attached to the eyeglasses 100, the nut 300 used for attaching the first member 200 to the eyeglasses 100, and the eyeglass attachment 400. The second member 500 attached to the eyeglass attachment 400 is provided. And about the spectacles 100, the spectacles attachment 400, and the nut 300, it is not different from the case of 1st Embodiment, and the method of attaching the 1st member 200 to the long screw 140B is not different from 1st Embodiment.
Further, the first member 200 of the eyeglass system of Modification 1 has the tube 210 and the connection plate 220 as in the case of the first embodiment, and the second member 500 of the eyeglass system of Modification 1 is the first embodiment. Similarly to the case, the connecting rod 510, the connecting body 520, the crank member 530, and the rod 540 are provided. Although these configurations are not substantially different from the case of the first embodiment, the crank member 530 is different from the case of the first embodiment so that it dive below the temple 100, the wisdom 130 or the lens (and the frame) of the glasses 100. It has become.
The eyeglass system according to the first modification is substantially different from the eyeglass system according to the first embodiment. In the eyeglass system according to the first modification, the eyeglass system according to the first embodiment is inserted into the tube 210 having an opening on the upper side from the lower end. The rod 540 that was supposed to be inserted is inserted into the cylinder 210 having an opening on the lower side from the upper end thereof. Further, in the first modification, the following configuration is adopted so that the rod 540 inserted into the cylinder 210 does not fall off from the cylinder 210.
A notch 211 is provided above the tube 210 of the eyeglass system of the first modification. The notch 211 has a part of the cylinder 210 cut away in the circumferential direction, and connects the space inside the cylinder 210 and the space outside the cylinder 210. In the first modification, a ring-shaped spring 212 is fitted on the outside of the tube 210. A part of the spring 212 is engaged with the notch 211, and the part enters the space inside the cylinder 210. The diameter of the spring 212 is somewhat smaller than the diameter of the tube 210, and the spring 212 is always subjected to an elastic force to reduce the diameter.
The rod 540 of the eyeglass system of Modification 1 has a groove 541 above it. The groove 541 is provided at a predetermined height of the rod 540 in the circumferential direction. The groove 541 may be provided so as to go around the circumferential direction of the rod 540, but is provided at a portion corresponding to the notch 211 at least when the rod 540 is inserted into the tube 210.
In order to fix the first member 200 and the second member 500 in the eyeglass system of the first modification, the rod 540 of the second member 500 is inserted into the cylinder 210 having an opening on the lower side of the first member 200 from the upper end. Include. When the rod 540 is inserted into the tube 210, the tip of the rod 540 eventually comes into contact with the spring 212 entering the tube 210. When the rod 540 is further inserted into the cylinder 210 as it is, the rod 540 further advances in the cylinder 210 while pushing the spring 212 against the elastic force of the spring 212. Eventually, the groove 541 of the bar 540 reaches the spring 212. When the groove 541 reaches the spring 212, the spring 212 is fitted into the groove 541 of the rod 540 by the elastic force to be contracted. The rod 540 in which the spring 212 and the groove 541 are engaged with each other cannot be removed from the tube 210. In this way, the fixing of the first member 200 and the second member 500 is completed.
The positional relationship of the spectacle attachment 400 with respect to the spectacles 100 in a state where the first member 200 and the second member 500 are fixed in this manner is the same as in the case of the first embodiment.
When it is no longer necessary for the user to attach the spectacle attachment 400 to the spectacles 100, such as when the user stops using the spectacle attachment 400, the user applies a strong force sufficient to allow the spring 212 to come out of the groove 541. Thus, the spectacle attachment 400 is moved downward relative to the spectacles 100. Then, the diameter of the spring 212 increases against the elastic force of the spring 212, and the spring 212 comes out of the groove 541. Further, when the eyeglasses 100 are lifted or the eyeglass attachment 400 is moved downward, the rod 540 comes out of the tube 210, so that the first member 200 and the second member 500 are fixed, and consequently the eyeglasses 100 and the eyeglass attachment 400. Is released.
In the first modification, in order to prevent the rod 540 inserted into the cylinder 210 from falling out of the cylinder 210, a part of the cylinder 210 is cut out and the cylinder 210 has a ring shape. The configuration in which the spring 212 is fitted and the groove 541 is provided in the rod 540 is adopted. However, in order to achieve the same purpose, the following configuration can also be adopted.
The configuration is such that a predetermined portion of the rod 540 (for example, the tip of the rod 540) and a predetermined portion of the tube 210 (for example, the lower surface of the cover when a lid is provided at the upper end of the tube 210) are adsorbed to each other. It is to provide a member to meet. The members that are attracted to each other can be a combination of a magnet and a magnet, or a combination of a magnet and a metal that is attracted to the magnet. In this case, when the rod 540 is inserted into the cylinder 210, the above-mentioned two members adsorbing each other adsorb each other, so that the rod 540 does not fall out of the cylinder 210. In order to remove the rod 540 from the cylinder 210, it is only necessary to pull out the rod 540 from the cylinder 210 by applying a force enough to separate the adsorbing two members from each other.
<Modification 2>
A spectacle system of Modification 2 will be described.
The eyeglass system of Modification 2 is substantially the same as the eyeglass system of the first embodiment.
As in the case of the first embodiment, the eyeglass system of Modification 2 includes eyeglasses 100, a first member 200 attached to the eyeglasses 100, a nut 300 used for attaching the first member 200 to the eyeglasses 100, and an eyeglass attachment 400. The second member 500 attached to the eyeglass attachment 400 is provided. And about the spectacles 100, the spectacles attachment 400, and the nut 300, it is not different from the case of 1st Embodiment, and the method of attaching the 1st member 200 to the long screw 140B is not different from 1st Embodiment.
The eyeglass system of the second modification is substantially different from the eyeglass system of the first embodiment in that the relationship between the tube 210 and the bar 540 in the second modification is changed. That is, in the second modification, the cylinder 210 is provided on the second member 500 and the bar 540 is provided on the first member 200.
The method of fixing the first member 200 and the second member 500 in the eyeglass system of Modification 2 is the same as in the case of the first embodiment when attention is paid to the movement of the tube 210 and the rod 540, and the description thereof is omitted. Description of the method for releasing the fixation of the first member 200 and the second member 500 is omitted for the same reason.
The eyeglass system of Modification 2 is the same as the eyeglass system of the first embodiment except for the above differences, but if it is necessary to prevent the tube 210, the rod 540, etc. from interfering with other members, Do it as needed. For example, if the relationship between the tube 210 and the rod 540 is simply changed, the tube 210 at the position of the rod 540 in FIG. 2 is completely inserted into the tube 210 when the rod 540 is inserted therein. Since the outer periphery of the cylinder 210 interferes with the hinge 120 before being inserted, the length of the cylinder 210 needs to be shorter than the distance from the tip of the bar 540 to the upper surface of the hinge plate 121 above the hinge 120. There is.
In the eyeglass system of the first modification, the relationship between the rod 540 and the tube 210 can be reversed.
<Modification 3>
A spectacle system according to Modification 3 will be described with reference to FIG.
The eyeglass system of Modification 3 is substantially the same as the eyeglass system of the first embodiment.
As in the case of the first embodiment, the eyeglass system of Modification 3 includes the eyeglasses 100, the first member 200 attached to the eyeglasses 100, the nut 300 used for attaching the first member 200 to the eyeglasses 100, and the eyeglass attachment 400. The second member 500 attached to the eyeglass attachment 400 is provided. And about the structure of the spectacles 100, the 1st member 200, and the nut 300, it is not different at all from the case of 1st Embodiment.
In the eyeglass system of Modification 3, the configuration of the second member 500 is different from that in the first embodiment.
The second member 500 of the eyeglass system of Modification 3 includes a bar 540 similar to that in the first embodiment. However, unlike the case of the first embodiment, the second member 500 of Modification 3 does not include the connection rod 510, the connection body 520, and the crank member 530.
Instead, the second member 500 of the third modification includes a fixing plate member 550 and a clamp 560 specialized for fixing the eyeglass attachment 400 that is formed into a cylindrical shape. The base of the fixed plate member 550 is fixed to the upper end of the bar 540. A slit 551 that runs in the length direction is provided on the base end side of the fixed plate member 550. The distal end side of the fixed plate member 550 is folded back in a ring shape as shown in FIG. 6B, and the distal end is in contact with the lower portion of the base end side portion of the fixed plate member 550.

It is naturally possible to combine the configurations of Modification 1 and Modification 2 with Modification 4.
<< Second Embodiment >>
Next, the eyeglass system of the second embodiment will be described with reference to FIGS.
As in the case of the first embodiment, the eyeglass system of the second embodiment includes the eyeglasses 100, the first member 200 attached to the eyeglasses 100, the eyeglass attachment 400, and the second member 500 attached to the eyeglass attachment 400. Yes.
However, unlike the case of the first embodiment, the eyeglass system of the second embodiment does not have the nut 300 which is a hexagonal nut in the first embodiment.
In the eyeglass system of the second embodiment, the configurations of the first member 200 and the second member 500 are also different from those of the first embodiment.
The first member 200 in the eyeglass system of the second embodiment has a shape as shown in FIG. The first member 200 is not necessarily limited to this, but is an integrally molded product made of resin. The first member 200 according to the second embodiment includes a plate-like connection piece 250 having a rectangular cross section in a state in which an elliptical first locking piece 230 and a circular second locking piece 240 are twisted by 90 degrees. It is a connected shape.
Although not necessarily limited to this, the first locking piece 230 is provided with a circular first hole 231 in this embodiment, and the second locking piece 240 is not necessarily limited to this. A second hole 241 that is circular in shape is formed.
The first member 200 of the second embodiment is used in the first embodiment using a nut 600 with a flange as shown in FIG. 9 different from the nut 300 used in the first embodiment. It is fixed to the same long screw 140B. Although not necessarily limited to this, the flanged nut 600 includes a circular flange portion 610 formed in a plate shape and a cylindrical threaded tube 620 coaxially.
The flange portion 610 is configured to be easily picked by a finger, and has a diameter of about 8 mm ± 4 mm, for example.
The inner peripheral surface of the hole 621 inside the threaded cylinder 620 is threaded. In this embodiment, the hole 621 also penetrates the flange portion 610, but this need not necessarily be the case.
The first member 200 is fixed to the screw 140B by screwing the screwing cylinder 620 of the nut 600 with flange through the first hole 231 of the first locking piece 230 with the screw 140B. The first member 200 is fixed to the screw 140B by sandwiching the first locking piece 230 between the upper surface of the flange portion 610 of the flanged nut 600 and the lower surface of the hinge plate 121 below the hinge 120. To do. The diameter of the 1st hole 231 is made larger than the outer diameter of the screwing cylinder 620 so that it is possible. In addition, although the specific numerical value of the diameter of the flange part 610 of the nut 600 with a flange is as above-mentioned, when performing the operation | work which fixes the nut 600 with a flange to the screw 140B, or removes the nut 600 with a flange from the screw 140B. In order to make it easier for the user to pick the flanged nut 600, the diameter of the flanged nut 600 is such that when the flanged nut 600 is fixed to the screw 140 B in plan view, a part of the diameter is from the first locking piece 230. It is made to eat out.
A ball receiver 580 is connected to the second hole 241 of the second locking piece 240 of the first member 200. The ball receiver 580 is configured in a shape as shown in FIG. The ball receiver 580 is not necessarily limited to this, but is an integrally molded product made of resin. The ball receiver 580 includes a cylindrical shaft member 581 and a receiving portion 583 having a receiving hole 582 that is a substantially hemispherical hole corresponding to the shape of the ball portion described later.
The base end of the shaft member 581 is inserted into the second hole 241 of the first member 200. The diameter of the base end of the shaft member 581 is substantially the same as that of the second hole 241 of the first member 200. When the base end of the shaft member 581 is inserted into the second hole 241 of the first member 200, the shaft member 581 is Although it can be slid to be positioned at a desired angle with respect to the two holes 241, it fits tightly into the second hole 241 with such a hardness that the angle with the second hole 241 can be fixed.
In the receiving hole 582 of the ball receiver 580, a ball 430 attached to the eyeglass attachment 400, which is a display that constitutes a head-mounted display in combination with the eyeglass 100, can be fitted. As shown in FIG. 11, in this embodiment, although not necessarily limited to this, the ball 430 is spherical and is fixed to the eyeglass attachment 400 via a cylindrical connecting rod 431. A ball joint is configured by a combination of the ball 430 and the receiving portion 583.
FIG. 12 shows a perspective view of the eyeglass 100 with the eyeglass attachment 400 attached thereto.
In this embodiment, the spectacles attachment 400 is attached via the ball receiver 580 to the first member 200 attached to the screw 140B as described above.
In this state, the user can view the image displayed on the display device by the image light emitted through the lens from the display device that is set in the tip portion bent into the key shape of the spectacle attachment 400. It becomes like this. When the positional relationship between the eyeglass attachment 400 and the user's eyes is not appropriate, the eyeglass attachment 400 is caused by the function of the ball joint formed by the ball 430 and the receiving portion 583 and the sliding of the shaft 581 with respect to the second hole 241. Can be adjusted.
When it is no longer necessary to use the spectacle attachment 400, the user removes the ball receiver 580 from the first member 200. Alternatively, the user removes the flanged nut 600 from the screw 140 B and removes the first member 200 and the spectacle attachment 400 from the spectacles 100. A configuration in which the base end of the shaft member 581 cannot be removed from the second hole 241 of the first member 200 is also possible. In this case, the user who does not need to use the spectacle attachment 400 removes the flanged nut 600 from the screw 140B, and removes the spectacle attachment 400 from the spectacles 100 together with the first member 200.
<< Third Embodiment >>
A spectacle system according to a third embodiment will be described with reference to FIGS. 13 and 14.
The eyeglass system of the third embodiment is substantially the same as the eyeglass system of the first embodiment.
As in the case of the first embodiment, the eyeglass system of the third embodiment includes the eyeglasses 100, the first member 200 attached to the eyeglasses 100, the nut 300 used for attaching the first member 200 to the eyeglasses 100, and the eyeglass attachment. 400, the 2nd member 500 attached to the attachment 400 for spectacles is provided. And about the spectacles 100, the spectacles attachment 400, and the nut 300, it is not different from the case of 1st Embodiment, and the method of attaching the 1st member 200 to the long screw 140B is not different from 1st Embodiment.
However, the configuration of the first member 200 of the eyeglass system of the third embodiment is slightly different from that of the first embodiment. The first member 200 of the eyeglass system of the third embodiment includes a connection plate 220 similar to that of the first embodiment as shown in the enlarged view of FIG. 14, but the cylinder 210 existing in the first embodiment. Not equipped. Instead, the first member 200 of the third embodiment includes a cylindrical magnet member 260 that extends substantially vertically when the first member 200 is attached to the screw 140B. The magnet member 260 includes magnets 261 at the upper and lower ends thereof.
The second member 500 of the eyeglass system of the third embodiment is a part of the eyeglass attachment 400.
The spectacles attachment 400 of the spectacle system of the third embodiment is a fatigue prevention tool for preventing dry eyes and the like by prompting the user to blink.
An eyeglass attachment 400 that is a fatigue prevention device includes a case 440 and a lens unit 450 through which a user looks at the outside. When the spectacle attachment 400 is attached to the spectacles 100, the lens unit 450 is positioned in a state substantially parallel to the lens immediately before one of the lenses of the spectacles 100 (right side in this embodiment). Yes. Case 440 includes processing for detecting the user's blink, processing for determining whether the number of blinks of the user based on the detected state of the user's blink is less than a predetermined reference, and the number of blinks of the user When the lens unit 450 is determined to be less than a predetermined reference, a process that causes the lens unit 450 to make a change that makes the user's field of view through the lens unit 450 more difficult to see than normal, and when the field of view is difficult to see When a user's blink is detected, a circuit is built in which a process for causing the lens unit 450 to change is canceled to restore the user's field of view. Among these processes, detection of the user's blink can be realized by performing image processing on an image of the user's eye captured by a small digital camera built in the case, for example. For example, when the area of the black eye becomes smaller than a certain reference value, it can be determined that the user has blinked. Each subsequent process can be executed by the above-described circuit. The circuit may be a general circuit including, for example, a CPU, a ROM, a RAM, and the like.
When such a spectacle attachment 400 is used, when the number of blinks of the user decreases, it becomes difficult to see the field of view viewed from the lens unit 450, so that the user who feels sparse can perform blinks. become able to. As a result, the number of blinks of the user can be kept above a certain number. The process for making it difficult to see the field of view is not particularly limited as long as the object is achieved. For example, the process of making it difficult to see the field of view may block the field of view. For example, the light shielding can be switched between a transparent state in which a voltage is applied and a white turbid state in which light that is not applied with voltage is scattered. This is possible. In addition, a predetermined pattern may be displayed on a portion of the lens unit 450 that hinders the user's field of view, or the pattern may be moved.
The case 440 is bent into an L shape when seen in a plan view, and includes a plate-like suction plate 441 extending substantially horizontally at a portion extending rearward thereof. The attraction plate 441 includes a magnetic body that adsorbs to the magnet, or a magnet 442 that adsorbs to the magnet 261 disposed above and below the magnet member 260.
The spectacles attachment 400 brings the upper suction plate 441 and the lower suction plate 441 closer together so as to sandwich the magnet member 260 from above and below, and the upper suction plate 441 and the lower suction plate 441 are connected to both ends of the magnet member 260. By adsorbing to each other, the eyeglasses 100 are fixed to the eyeglasses 100 while being positioned at appropriate positions with respect to the eyeglasses 100.
When it is not necessary to use the spectacle attachment 400, the suction plate 441 may be removed from the magnet member 260 against the suction force generated between the magnet member 260 and the suction plate 441. In the case of this embodiment, the first member 200 remains on the glasses 100.
In the third embodiment, the magnets 261 are arranged at the upper and lower ends of the magnet member 260, and the magnets 442 and magnetic bodies that can be attracted to the magnet 261 are arranged on the upper and lower adsorption plates 441. Of course, a magnet may be disposed on the lower attracting plate 441, and a magnet or a magnetic material that can be attracted to the magnet of the attracting plate 441 may be disposed on both upper and lower ends of the magnet member 260.
