Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to an improvement in eyeglasses that are freely drawable.

[Requirement of the invention]

Eyeglasses according to the invention have a pair of channels formed in the frame of the eyeglasses for receiving respective glasses. These bells can also be pulled out and swung into position intersecting the frame in order to be ready for use.

[Conventional technology]

Glasses, such as ordinary glasses, sunglasses, stereoscopes, polarized lenses, protective glasses, etc. (hereinafter simply referred to as "glasses")
consists of a frame having a pair of lens receiving parts that support respective lenses and a bridge that connects these lens receiving parts to each other. A temple is pivotally attached to the lens receiving portion, and an ear temple is provided on this temple.

When the glasses are worn, the frame is supported on the wearer's nose by a bridge, the lenses are positioned in front of the eyes, and the temples extend back over the wearer's temporal region, e.g. It is attached to the wearer's ear with a string.

By the way, eyeglasses have various uses, but to mention a few here, for example, eyeglasses include ordinary eyeglasses equipped with corrective lenses or lenses to aid normal vision. These glasses are specially tailored for the wearer or for magnification or other purposes.

Sunglasses are then used as filters or attenuators to protect the eyes from the sun.

A stereoscope, on the other hand, is used to obtain a three-dimensional illusion from two distinct images created by polarization or color effects.

Colored lens glasses are then simply used for some new purpose rather than filtering sunlight.

In addition, glasses are used to protect the eyes against vapors, liquid droplets and airborne particles.

In addition, synthetic resin materials are used for conventional frames,
Other materials such as wire or metal may also be used in whole or in part.

Also, eyeglasses for occasional or one-time use, such as sunglasses or glasses for viewing 3D movies, may be made of materials such as cardboard or paperboard for low cost and wide distribution. used.

Modern eyeglasses are desired to have a compact structure. In its standard construction, the temple of the spectacles is permanently pivoted to the outer edge of the frame. This temple can swing inward, and the folded glasses are
It can be stored in a glasses bag and stored in a pocket or other storage location. Sometimes hinges or flexible joints are also provided on the bridges to allow the glasses to be folded to make them more compact.

[Problem to be solved by the invention]

The configurations described above help keep the glasses relatively compact, but they still leave the glasses somewhat thicker. However, in some cases, it is desirable for eyeglasses to be extremely flat and thin.

[Means to solve the problem]

The present invention includes a rigid member having channels overlying the lens in contact with the lens component and supporting said lens component, and a rigid member receiving said channels and extending from said channels at opposite ends of said rigid member. A freely drawable drawer consisting of a pair of temples that can be respectively drawn out and that can be pivoted relative to the rigid member so that each can be placed along the side of the user's head when being pulled out from the channel. It relates to glasses with temples.

[Effect]

Therefore, by storing the temples in the channels when the glasses are not in use, the glasses can be kept in a flat state with a thickness substantially equal to that of the rigid member supporting the lens components.

〔Example〕

The following is a first example of applying the present invention to ordinary eyeglasses.
This will be explained with reference to FIGS.

The eyeglasses of this embodiment include a flat, reduced thickness frame, and the frame is provided with at least one channel extending across the lens-receiving portion of the frame and through the bridge.

Furthermore, this channel is open at the end of the frame so that the temple can be at least partially withdrawn from this channel and pivoted into a position of use. Note that the temples swung as described above occupy a position substantially perpendicular to the planes of the frame and the channel.

Typically, the channel accommodates two of the temples, and each temple is pulled out of the channel in a substantially straight line along the axis of the channel before the temple is rocked.

Such an arrangement has the advantage of allowing the majority of the temples to be accommodated in the frame even though the frame has a flat, preferably planar, shape. Therefore, there is no need for the above-mentioned temples to have a folding structure, or even for the above-mentioned temples to be nested. Furthermore, the above-mentioned telescoping tendrils of varying diameters and successive insertions increase the complexity of production and use.

A temple of any material can be used in the spectacles according to the invention. Temples made of plastic materials, wire and other materials commonly used in eyeglasses can also be used.

Furthermore, the ear clip provided on the temple of the present invention remains protruding from the channel when the temple is housed in the channel. As a result, this earbud functions as a holder when pulling the earbud out of the channel.

Note that in order to make the glasses more compact, the earrings may be partially housed within the frame, unlike the case described above. Further, the free end of the temple remote from the ear temple is provided with, for example, a cross-shaped head so that the shaft of the temple is not completely pulled out of the channel.

The frame of the spectacles can be molded in one or more parts from a synthetic resin material. Also, as mentioned above, 1
When molding in more than one part, it has been found advantageous to provide two separate, mutually parallel channels in which each temple can be accommodated. It should be noted that the temples may be more or less rigid, and each temple may be provided with means at its inner end for allowing rocking movement about a pivot point located at the end of the respective channel.

In the above case each channel is open only at one end of the frame and closed at the other end of this frame. Also, one channel may lie in front of the other channel or may lie above the other channel.

In an embodiment, the temple is rigid and has an ear temple pivotally attached to it. and this elongated ear cane can be positioned, by means of angle indexing means, in a position substantially perpendicular to said temple and in a position at an obtuse angle to said temple, and can be oscillated between these positions. be able to.

If the earbuds occupy the orthogonal position when the temples are housed in the channel, the earbuds can lie near the side ends of the frame. Therefore, the glasses are made more compact. Note that the obtuse angle position of the earbud corresponds to the position in which the earbud is used, and is of course a more comfortable position for the eyeglass wearer.

The channel is formed from upper and lower mating members, which are held together by a U-section in the frame, which comprises a lens-receiving portion and the like. Note that the lens receiving portion may include a nose pad that extends downward from the U-shaped cross section and engages the bridge of the wearer's nose.

Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

The frame 40 of the spectacles shown in FIGS. 1 to 3, which has a substantially flat shape, is comprised of a pair of lens receiving portions 41 and 42, etc., which together with lenses 46 and 47 form a lens component. These lens receiving portions 41 and 42 are also interconnected by a bridge 43. Note that this bridge 43 is rigidly molded together with the lens receiving parts 41 and 42, and the lens receiving parts 41 and 42 are provided with windows 44.45 for receiving the above-mentioned lenses 46.47.

In this embodiment, channels 48 are provided in the straight and rigid portion formed by the upper portions of lens receiving portions 41 and 42 and bridge 43, and one common channel is provided in the two temples 50. and 51 (Figs. 2 and 3)
Although only one channel is shown in the figure, it is clear that separate channels could be provided if desired (see Figures 4 and 5). .

A temple 50,51 is formed with an ear temple 52 so that it can be pulled out of a passage 53 provided at the end of the frame and pivoted into a socket 59 which is open towards the rear. It protrudes from the passage 53. Note that the amount of pull-out of the temples 50, 51 is limited by the bulging end 55 provided at the end of the temple.

By the way, as shown by the solid lines in FIGS. 1 and 2, in the retracted position, the temple is almost completely received within the channel, leaving only the ear temple 52 exposed. The earrings 52 are approximately located within a plane formed by the frame.

However, when the tendril is pulled out, it is swung into the position indicated by the dash-dotted line at 56 and 57.
It is in its normal, usable state in which it engages the user's head. It should be noted that in the case of the two embodiments described above, the channel can be formed of a tubular member which can be attached to the frame element by conventional means, such as by heat sealing, gluing or the like.

In the embodiment shown in FIGS. 4 and 5 of a frame 90 based on the above principles, a pair of channels 91 and 92 in front-to-back position pass over the two lenses and across the bridge of the spectacles. It is installed inside a rigid rod-shaped body. This rod-shaped body is composed of a base portion 93 and a cover portion 94, each of which is made of injection molded synthetic resin, and when fitted together as shown in FIG. 4, forms two channels.

The two combination members 93 and 94 are thus held together in a U-section 95 provided in the lens component 96. Also as seen in FIGS. 4 and 5, channels 91 and 92 receive temples 97 and 98, respectively. In FIG. 5, the temples 97 and 98 are shown in a swung state. Hinges are provided at positions 99 and 100 for the temples, respectively, which, upon reaching the end of the channel, are swung inwardly to the position shown in FIG.

Next, as shown in FIGS. 6 and 7, the temple 97 is provided with an ear temple. That is, the temple 97 has at its free end a circular ledge 101 that is thinner than the temple 97, and this ledge 101 is provided with a pair of pins 102, 103 projecting from both sides thereof. Note that these pair of pins 102 and 103 become the rotational axis of the ear clip 110 that is slid and stacked on the above-mentioned projection. Furthermore, since these rotating shafts are provided with slopes 104 so that the forked ends of the ear clips can be easily opened, the ear clips can be reliably fitted onto the rotating shafts.

Further, each of the protrusions 101 has a pair of protrusions 105.
．． A protrusion 107 is provided so as to serve as a means for preventing rotation of the earring, and a protrusion 107 as a stopper.

As is clear from FIGS. 8 and 9, the earring 110 has a low left carved on its surface, a fork-shaped end that is overlapped and snapped onto the rotating shaft, and a hole 112 into which the rotating shaft is inserted. Equipped with. Thus, the ear temple is allowed to rotate within a predetermined range while contacting the temple. Note that the depression 113 accommodates the protrusion 107.

Thus, as shown in FIG. 11, the earrings can be held in two positions as shown by the angular indexing means. That is, at the position indicated by the dashed line, the ear temple is substantially perpendicular to the temple. Thus, when the temple is fully inserted into the channel, the temple tightens its position near the side of the frame, compacting the shape of the glasses.

Also, the earrings are used for their original purpose when they occupy the position indicated by the solid line. It should be noted that in addition to the above-mentioned detent means or ratchets can be further provided in order to add a position where comfort is guaranteed. Further, FIG. 10 shows details of the lens component 96, and reference numeral 114 indicates a lens.

As seen above (in the examples, the case where the present invention is applied to some eyeglasses has been explained, but the present invention is of course
It can be applied to various other eyeglasses.

In other words, in addition to ordinary eyeglasses, sunglasses, stereoscopes, polarized lens mirrors, protective glasses, etc., long-life glasses that can be used repeatedly - single-use disposable glasses, glass lens mirrors, etc.
The invention also applies to synthetic resin (plastic) lens mirrors, eyeglasses, etc., which are supplied or stored in a compact form, with the temples being housed at least partially in the bridge between the lenses or in a frame lying over the lenses. Is possible.

〔Effect of the invention〕

Since the present invention has the above-described configuration, the shape of the glasses can be made flatter and thinner than conventional glasses. Moreover, the functionality of the glasses is increased by this.

Moreover, since the shape of the glasses is simple, flat, and compact, the disadvantages of conventional glasses can be avoided.
