Description

  The present invention relates to a spectacle attachment attachment / detachment mechanism for detachably attaching spectacle attachments to spectacles.

The glasses are used over the ears of the user in everyday life, and it is considered convenient to use various glasses attached to the glasses.
For example, it is conceivable to attach a small image display device to spectacles and use it as a head-mounted display, or attach a small camera to spectacles and take a picture of what is in his field of view.
An attachment for spectacles that is used by attaching to spectacles such as a small image display device or a camera can be used by attaching to spectacles when in use, and is removed from the spectacles when not in use, and the spectacles themselves are removed. It must be configured to be detachable from the glasses so that it can be used as normal glasses.

An example of an attachment member used for detachably attaching the spectacle attachment to the spectacles is a pair of magnet members. This magnet member is used when the spectacles vine is made of metal. One magnet member is fixedly attached to the spectacle attachment, and the inner side of the spectacle vine at the time of installation (when the spectacles are put on, the user's A pair of magnet members sandwiched between the pair of magnet members, and the magnetic force attracts both magnet members to the temples of the glasses. The eyeglass attachment is detachably attached to the eyeglasses.
Further, as a method for detachably attaching the spectacle attachment to the spectacles, a support hole for fitting a predetermined screw is provided on the outside of the spectacle attachment, and the screw shaft of the predetermined screw is passed through the spectacle vine. If necessary, insert a predetermined screw through the screw hole of the eyeglass vine from the inside to the outside (the side farther from the user's body when wearing glasses). It is also conceivable that the spectacle attachment is detachably attached to the spectacles by fitting the penetrating screw shaft portion into the support hole.
According to these attachment methods, the attachment for glasses can be detachably attached to the glasses.

However, when the magnet member is used for attaching the spectacle attachment to the spectacles as in the former, it is necessary to sandwich the spectacle vine while adjusting the position of the magnet so that the position of the spectacle attachment attached is an appropriate position. There is. Also, when using screws to attach eyeglass attachments to eyeglasses like the latter, insert a predetermined screw into the screw hole of eyeglasses from the inside to the outside, and support the part of the screw shaft that penetrates the screw hole It is necessary to perform an installation operation for fitting into the hole and a removal operation for removing the screw from the support hole.
That is, in the conventional mounting method as described above, it takes time to position and attach / detach the eyeglass attachment.
The eyeglass attachment is attached to the eyeglass when it is used, and it is removed from the eyeglass when it is not in use, and frequent attachment / detachment to / from the eyeglass is scheduled, and it takes time and effort for positioning work and attachment / detachment work. The use of the spectacle attachment may cause the spectacle user to refrain from using it.

  The present invention solves the above-described problems, and an object of the present invention is to provide a technique for facilitating positioning work and attaching / detaching work of spectacle attachments to spectacles.

  The inventor of the present application proposes the following attachment / detachment mechanism, spectacle mounting unit, spectacle unit, spectacles, and spectacle system as an invention that can solve the above-described problems.

The attachment for spectacles can be removed from the spectacles. In short, according to this attachment / detachment mechanism, the operation of positioning the attachment for glasses to the glasses is unnecessary, and the attachment / detachment operation can be facilitated.

The attachment for spectacles may be anything as long as it is attached to the spectacles and used.
For example, when the spectacle attachment is used by being attached to the attachment vine by the attachment / detachment mechanism of the spectacle attachment, the attachment of the user located near the attachment vine when the spectacles are fixed to the user's body is used. It is located at a use position in front of one eye, and is present in a display range that is a part of the field of view of the one eye by guiding image light of a predetermined image to the one eye. In this state, the image display apparatus may include a display unit that allows the one eye to see the image. By attaching such an image display device to the eyeglass attachment vine, a head-mounted display device is configured by combination with the eyeglasses.
The eyeglass attachment may be a small camera or a portable music player.

  The shape of the convex portion of the first member and the concave portion of the second member may be any shape as long as it is formed into a shape that can be fitted into each other.

For example, the convex portion of the first member has a cylindrical shape, and when the cylindrical convex portion is fitted into the concave portion of the second member, the concave portion is the cylindrical convex portion. It may be slidable in the direction around the axis and fixed at an arbitrary angle.
When a small image display device is used as an attachment for spectacles and the image display device is attached to the spectacles and the image is viewed, the orientation and angle of the image display device can be adjusted so that the image display device is positioned where it is easy to see If possible, it will be easy to use. In addition, when a small camera is used as an eyeglass attachment and a predetermined imaging object is imaged by attaching it to the eyeglass, the orientation and angle of the small camera are adjusted so that the imaging object can be appropriately imaged. If it can, it will be easy to use.
According to the attaching / detaching mechanism having the convex portion configured in the shape as described above and the concave portion corresponding to the convex portion, the concave portion is slidable in the direction around the axis of the cylindrical convex portion. The spectacle attachment attached to the spectacles can be moved in the direction around the axis of the convex portion by the attaching / detaching mechanism, and the direction of the spectacle attachment relative to the spectacles (the vertical position of the eye of the user wearing the spectacles) is adjusted. Can do.

Moreover, the said convex part of the said 1st member is comprised by the barrel shape gradually expanded toward the center part from the edge part of the thickness direction, The said convex part of the said barrel shape is the said recessed part of the said 2nd member. The recess may be slidable in a direction around the axis of the barrel-shaped projection and in a direction substantially perpendicular to the direction around the axis.
According to such an attaching / detaching mechanism, the concave portion is slidable in the direction around the axis of the barrel-shaped convex part and in the direction substantially perpendicular to the direction around the axis. The attachment can be moved in a direction substantially perpendicular to the axis direction in addition to the direction around the axis of the convex part, and the direction and angle of the eyeglass attachment with respect to the eyeglass (the position of the eye of the user wearing the eyeglass in the left-right direction) Can be adjusted. That is, by using this attachment / detachment mechanism, the attachment for glasses can be attached to the glasses detachably while the direction and angle of the attachment for glasses attached to the glasses can be adjusted.

The 2nd member used with the 1st member comprised in this barrel shape can be constituted as follows, for example.
The second member includes a U-shaped member having a substantially U-shaped cross section and a spring. The U-shaped member has a deformable elasticity, and the spring is The U-shaped member is attached to the U-shaped member so that the force acts in a direction in which the end portions of the U-shaped member are brought close to each other. When the convex portion including a portion having a large diameter is fitted into the concave portion, the end portions of the U-shaped members are separated from each other against the force of the spring. The U-shaped portion is widened to the extent that the portion of the convex portion having a diameter larger than the diameter can be received, and the portion of the convex portion having a diameter larger than the diameter of the concave portion is received in the concave portion. When the end portions of the members are close to each other by the force of the spring, Serial recess is adapted to press said protrusions in its inner surface.
According to such a 2nd member, fitting of the convex part to a recessed part and extraction of the convex part from a recessed part can be performed easily.

In order to attach the image display device 100 to the glasses 200, the first member 10 fixedly attached to the temple 210 of the glasses 200 is inserted into the through-hole 24 of the second member 20 fixedly attached to the image display device 100. The first member 10 may be inserted into the through hole 24 of the second member 20 by pushing.
Specifically, when the first member 10 is pushed into the through hole 24, the ends of the U-shaped member 21 are separated from each other against the force of the coil spring 23, and the diameter of the first member 10 is larger than that of the through hole 24. The diameter of the through hole 24 is expanded to such an extent that the portion can be received. Further, when the first member 10 is pushed in and a portion of the first member 10 having a diameter larger than the diameter of the through hole 24 passes, the ends of the U-shaped member 21 come close to each other by the force of the coil spring 23, The size of the diameter narrows and returns to the original size. In this way, the first member 10 can be fitted into the through hole 24 of the second member 20.
That is, the mounting operation of the image display device 100 is performed by only fitting the first member 10 fixedly attached to the mounting vine 210 of the eyeglass 200 into the through hole 24 of the second member fixedly attached to the image display device 100. It can be installed with one touch.
FIG. 5 shows a state in which the image display apparatus 100 is attached to the glasses 200 as described above, and is a diagram showing the eyeglass system of the present embodiment.
5A shows a state where the image display unit 120 in the image display apparatus 100 is in the standby position, and FIG. 5B shows a state where the image display unit 120 is in the use position. 5A and 5B are both plan sectional views, but the right half of the glasses 200 is not shown.
Since the thickness of the 1st member 10 of this embodiment and the thickness of the 2nd member 20 are substantially the same, as shown in this figure, the 1st member 10 was inserted in the through-hole 24 of the 2nd member 20. In this case, the thickness thereof is substantially the same as the thickness of the first member 10 or the second member 20, and can be not bulky.
Note that the image display apparatus 100 can be fixed to both the temples 210 of the two glasses 200 or can be fixed to only one side of the temple 210. In this embodiment, the image display device 100 is fixed to both the temples 210 of the two glasses 200.

Next, a method for using the image display device 100 attached to the glasses 200 will be described.
When using the image display device 100 attached to the glasses 200, the user wears the glasses 200 to which the image display device 100 is fixed on the head. In this embodiment, such wearing is performed by locking each of the two vines 210 to each of the user's ears.

In this state, the image display unit 120 of the image display apparatus 100 is at the position shown in FIG. At this time, the position where the image display unit 120 exists is the standby position.
Here, the user operates a switch of a controller (not shown) to move the image display unit 120 to the use position. The controller generates a signal instructing to move the image display unit 120 and sends it to the main body control board 115. The main body control board 115 receives the signal by an antenna incorporated therein and drives the motor 112.
When the motor 112 is driven, the motor shaft 112A of the motor 112 rotates and the worm gear 113 rotates. Accordingly, the moving body 114 starts moving upward in FIG. When the moving body 114 moves, the connection body 119 connected to the moving body 114, the leaf spring 118 whose base end is connected to the connection body 119, and the image display unit attached to the distal end of the leaf spring 118. 120 moves upward in FIG.
Incidentally, as described above, the rail 117 has a tip that curves toward the front of the lens 220 of the eyeglass 200 on the side close to the vine 210 to which the image display apparatus 100 having the rail 117 is attached. Therefore, the leaf spring 118 bends in the direction of the lens 220 of the eyeglass 200 when the movable body 114 reaches the distal end side (the upper side in FIG. 5) of the worm gear 113 shown in FIG. As a result, the image display unit 120 changes its orientation by approximately 90 ° compared to when the image display unit 120 is in the standby position, and becomes substantially parallel to the lens 220 of the glasses 200. As described above, the leaf spring 118 has a strong spring property. In the state shown in FIG. 5B, the leaf spring 118 tends to extend toward the outer side of the curve of the rail 117 (more accurately, the inner surface of the groove of the rail 117). In other words, the inner surface of the groove is pressed against the surface located outside the curve. As a result, the leaf spring 118 can stably maintain the shape shown in FIG. 5B, so that the image display unit 120 can be securely held. Incidentally, the position where the image display unit 120 shown in FIG. 5B exists is the use position. The image display unit 120 is automatically positioned at the use position by the operation of the switch.
Note that the use position of the image display unit 120 may be changed when the user desires. For example, information on how far the moving body 114 is moved when the image display unit 120 is moved to the use position is stored in, for example, a memory (not shown) included in the main body control board 115 or a memory (not shown) inside the controller. This can be easily realized by recording.

In this state, the user adjusts the angle of the display unit case 122 included in the image display unit 120 using the above-described spherical joint. Since this adjustment does not need to be performed frequently once it is performed, it is difficult for the user to make a burden.
In the present embodiment, the image display device 100 is attached to the glasses 200 by an attaching / detaching mechanism. In this attaching / detaching mechanism, the through hole 24 of the second member 20 is the axis of the barrel-shaped first member 10. Since it is slidable in the circumferential direction and in a direction substantially perpendicular to the axial direction, the image display device 100 attached to the spectacles 200 is added to the axial direction of the first member 10 by this attachment / detachment mechanism. Since it can be moved in a direction substantially perpendicular to the direction and positioned at an appropriate position, the direction and angle of the image display device 100 with respect to the glasses 200 can be finely adjusted.
That is, the user can adjust the orientation and angle of the image display apparatus 100 with respect to the glasses 200 while viewing the image, for example.

In this state, the user can send the data about the image from the controller to the image display unit 120 by operating the controller.
The display unit control board 124 in the image display unit 120 receives the data by an antenna built in it and sends it to the display 125. The display 125 displays an image based on the data. The light for the image displayed on the display 125 exits the display 125, passes through the free-form surface prism 126, passes through the lens 220 of the glasses 200, and reaches the user's eyes. Thereby, the user can use the glasses 200 to which the image display device 100 is attached as a head-mounted display device. In addition, the path | route of the light which came out of the display 125 is shown by the code | symbol of L in FIG.5 (b).

When the user finishes viewing the image, the user stops transmission of data from the controller to the image display unit 120 and moves the image display unit 120 to the standby position. Manipulate. The controller generates a signal instructing to move the image display unit 120 and sends it to the main body control board 115. The main body control board 115 receives the signal by an antenna incorporated therein and drives the motor 112.
When the motor 112 is driven, the motor shaft 112A of the motor 112 rotates in the opposite direction to the previous case, and accordingly, the worm gear 113 rotates in the opposite direction. Accordingly, the moving body 114 starts moving in the downward direction in FIG. When the moving body 114 moves, the connecting body 119, the leaf spring 118, and the image display unit 120 move downward in FIG. 5B. As a result, the image display unit 120 returns to the standby position shown in FIG.

The user may remove the glasses 200 or keep wearing the glasses 200 as they are.
Further, the image display device 100 may be detached from the glasses 200 and another spectacle attachment may be attached.
The image display device 100 can be removed only by pulling the first member 10 out of the through hole 24 of the second member 20 and can be removed with one touch.

  Thus, according to the attachment / detachment mechanism for the spectacles attachment of the present embodiment, the positioning operation and the attachment / detachment operation of the spectacle attachment to the spectacles can be facilitated.

  In the present embodiment, the first member 10 constituting the attachment / detachment mechanism for the spectacles attachment is described as being configured in a barrel shape, and the second member 20 is described as corresponding thereto. However, the first member includes a convex portion and a spectacle mounting portion for mounting the first member on the outer side of the mounting vine, and the second member corresponds to the shape of the convex portion of the first member. And a second attachment member for attaching the second member to the spectacle attachment, and the convex portion of the first member can be detachably fitted into the concave portion of the second member. Any configuration may be used as long as it is configured as described above.

  The shape of the convex part of the first member and the concave part of the second member may be any shape as long as it is formed in a shape that can be fitted into each other. For example, the convex part of the first member is a cylinder. When the cylindrical convex portion is fitted into the concave portion of the second member, the concave portion may be slidable in the direction around the axis of the cylindrical convex portion. According to the attaching / detaching mechanism configured as described above, the concave portion is slidable in the direction around the axis of the cylindrical convex portion, and therefore the spectacle attachment attached to the spectacles by the attaching / detaching mechanism is attached to the axis of the convex portion. It can be moved in the circumferential direction, and the direction of the spectacle attachment relative to the spectacles can be adjusted.

Further, instead of fixedly attaching the first member to the spectacles, spectacles in which convex portions for detachably attaching the spectacle attachment can be used outside the spectacle attachment vine may be used. This convex part is comprised in the shape corresponding to the shape of the recessed member attached to the attachment for spectacles, and it is comprised so that it can detachably fit in this recessed member.
Since such a pair of spectacles has a convex portion corresponding to the convex portion of the first member of the attachment / detachment mechanism described above on the outside of the mounting vine, the convex portion is attached to the concave member attached to any spectacle attachment. The part can be fitted, and the attachment for spectacles can be easily attached to and detached from the spectacles.
