Description

Simple glasses-shaped frame

Technical Field

The present invention relates to a disposable simple spectacle-shaped frame integrally formed in a plate shape, which is used for being turned upside down and used separately as different types of lenses, wearable terminal lenses, and the like.

Background

Generally, as glasses in which different types of lenses are arranged in the upper and lower directions so as to be used in a distinguishable manner, there are known glasses for both near and far use. In the present situation, the upper portion of one lens is used for far vision and the lower portion thereof is used for near vision, and the wearer of the spectacles changes the direction and observation angle of the eyeball so that the eye looks upward when observing a distant object and downward when observing a near object. In the case of observing a particularly close object, the line of sight is directed downward from a horizontal position to observe the object, and therefore discomfort is likely to occur in an unnatural observation mode or an unnatural use mode with respect to a natural posture in which the object is viewed in front (observation with the line of sight with the center of the lens aligned with the position of the eyes), and eyestrain is likely to be induced.

Therefore, a number of solutions are proposed: a means for bringing the lower myopic region close to the eye position to bring the eye line close to emmetropia; the glasses are inverted; or the height of the glasses is close to the position of the eyes by adjusting the up-and-down height of the nose support position, and the like.

Among them, as a means for vertically inverting the eyeglasses themselves, there is (japanese) utility model No. 3031992 in which upper and lower ear-receiving portions are simply integrated in the original shape. However, in the case of the glasses using the above-described configuration, the upper and lower ear pads are present, which is not beautiful and gives a sense of incongruity, and thus the practicability is poor. Further, if the line of sight is directed toward the center of the lower lens when viewing through the lens, the line of sight is tilted forward with respect to the center line (horizontal line) of the lower lens, and is angled, so that it is difficult to bring the line of sight into a front view state.

On the other hand, the following simple spectacle-shaped frame has not been proposed so far: the lens is made of plate-shaped paper or synthetic resin, and different types of lenses can be used in a vertically reversed manner.

Further, there are many proposals for a frame made of paper and having a single kind of lens. For example, there are Japanese Kaiko Hei 1-142921, (Japanese Kaiko Hei 1-171416, (Japanese Utility model patent No. 3105983) and the like. These solutions do not allow the two lenses to be used separately, nor do they teach the concept of using them separately. The concept of using a combination of a lens and a wearable terminal lens is even less taught.

Detailed Description

An embodiment of the present invention will be described with reference to fig. 1A to 1C and fig. 2. The whole product of the invention is integrally formed by a piece of paper or a synthetic resin thin plate and the like. The product of the present invention may be bent to form a goggle shape. The pair of lens holding frame portions 1 are used for attaching and holding a plate-shaped lens A, B arranged vertically, two holes are bored in the lens holding frame portions 1, and the lens holding frame portions 1 are formed of a sheet of paper or synthetic resin or the like. As the plate-shaped lens held by the lens holding frame portion 1, a lens that functions as a concave lens or a convex lens, a flat mirror (transparent or polarizing plate), a colored mirror (sunglasses, etc.), a plate-shaped wearable terminal mirror, and the like are preferably used. The shape of the lens is not limited to the quadrangle shown in fig. 1A to 1C, fig. 2, and the like, and may be other shapes. In addition, the lens A, B preferably includes a single lens rather than two separate lenses. The two-dot chain line in the figure indicates the center of the lens a, and the one-dot chain line indicates the center of the lens B.

The intermediate beam portion 2 connects the pair of lens holding frame portions 1. The pair of leg portions 3 extend in the horizontal direction from the lens holding frame portion 1, and are formed so as to be foldable on the base side. The width W of the temple portion 3 may be formed in the following range: from a width corresponding to the interval between the centers of the lenses A, B as shown in fig. 1A to a width corresponding to the width (vertical dimension) of the lens holding frame 1 as shown in fig. 1C. In particular, when the temple portion 3 having the width W shown in fig. 1A is formed, the edge 31 of the temple portion 3 is preferably located at a position aligned with the center of the lens a or the lens B. The leg portion 3 is bent at a right angle to the lens holding frame portion 1. When the temple portion 3 having the width W shown in fig. 1B or 1C is formed, the lens holding frame portion 1 is inclined forward (see fig. 5) when the product of the present invention is worn, and the inclination angle θ is preferably in the range of 5 degrees to 20 degrees. At this time, when the inclination angle θ is 20 degrees or more, the optical axis of the lens and the line of sight are inclined, and thus astigmatism may be mixed. When the width W of the temple portion 3 increases, the inclination angle θ increases. At this time, when the width of the lens holding frame portion 1 is difficult to correspond to the desired width W, the width of the lens holding frame portion 1 is increased.

The ear pad 4 is formed at the rear end of the temple 3. The nose pad portion 5 is provided at the vertical center of the middle beam portion 2, and is provided so as to be able to support the lens holding frame portion 1 by abutting against the nose portion when vertically reversed. In addition, as for the nose pad portion 5, there are two forms as follows: is cut into a V shape as shown in figures 1A-1C and 2; as shown in fig. 3, a plurality of block pieces 51 of soft material for supporting the nose portion are attached. As the soft material of the block piece 51, a sponge is preferably used, but not limited thereto. When the block piece 51 is attached, the attachment can be performed according to the size of the face. The fold-in line 6 is a valley fold line (valley fold) located on the inner side of the lens holding frame portion 1 and the leg portion 3 and at the boundary therebetween, and the fold-in line 6 is for enabling folding of the leg portion 3.

Next, a case of producing the product of the present invention will be described. First, a sheet of thick paper or a thin plate of a synthetic resin plate is prepared, punched out into a predetermined shape by a press machine or the like, and the fold-in line 6 is added to the boundary between the lens holding frame portion 1 and the temple portion 3. Storing and placing multiple products in the state. In this case, the resin composition may be produced by molding a synthetic resin into a predetermined shape. Then, a plate-shaped lens or a plate-shaped wearable terminal mirror or the like corresponding to the application is combined, and the combined assembly is attached to the lens holding frame portion 1, whereby the lens or the wearable terminal mirror can be used as eyeglasses. In this case, the lens or the like may be attached to the back side or the front side of the hole of the lens holding frame portion 1. In the case of using the product of the present invention, the base portion of the temple portion 3 is bent along the fold line 6 and is substantially perpendicular to the lens holding frame portion 1. When not in use, the temple portion 3 may be folded back to be formed into a substantially planar shape for storage.

Next, a method of using the present invention will be described. First, the following is explained: as shown in fig. 1A or 2, the temple portion 3 is used with the width W corresponding to the interval between the centers of the lenses A, B. At this time, the edge 31 of the temple portion 3 is aligned with the center of the lens a or the lens B. First, when the product of the present invention is worn as shown in fig. 4, the center line (horizontal line) of the lens B is aligned with the position of the eyes, and therefore, the object can be observed with a front view, and eye fatigue can be significantly reduced. Next, when the lens a is used, the whole is inverted vertically and worn again, and thus the center line (horizontal line) of the lens a is aligned with the position of the eyes, so that the user can look straight at the time of observing an object, as in the case of the lens B, and eye fatigue can be significantly reduced.

Next, the operation of the present invention will be described with reference to fig. 5. This is the case where the temple portion 3 having the width W shown in fig. 1C is used, and the width W of the temple portion 3 corresponds to the width of the lens holding frame portion 1 as compared with the case of fig. 4. First, when the product of the present invention is worn as shown in fig. 5, the abutment position of the nose pad portion 5 and the position of the ear pad portion 4 are not changed, and therefore, the temple portion 3 is tilted forward, and the lens holding frame portion 1 is also tilted forward in the same manner. The inclination angle θ in this case may be in the range of 5 degrees to 20 degrees. Even if the width W of the leg portion 3 is increased to the width of the lens holding frame portion 1, the vertical width of the hole of the lens holding frame portion 1 may be increased to correspond to the inclination angle θ of not 20 degrees.

In this way, the lens is tilted forward to align the center of the lens with the position of the eye, and the lens is used in the same manner as conventional eyeglasses. The tilt angle θ in this case may be determined according to the type of lens to be attached. For reference, it is preferable that the width W of the temple portion 3 is determined so that the inclination angle θ is in the range of 15 degrees to 20 degrees when the lens for near vision is set; when a lens for telescopic vision is provided, the width W of the temple portion 3 is determined so that the inclination angle θ is in the range of 5 degrees to 15 degrees. At this time, the center (optical axis) of the lens is substantially aligned with the position of the eye as shown in fig. 5. On the other hand, when a flat mirror (transparent or polarizing plate), a colored mirror (sun mirror or the like), a plate-shaped wearable terminal mirror or the like is used, the inclination angle θ is preferably not provided.

Further, a specific example will be described in which different types of lenses are arranged in the upper and lower sides of the lens holding frame portion 1. For example, if sunglasses are used as the lenses a and convex lenses are used as the lenses B, the lenses B are used when the car navigation system, the audio equipment, or the like in the driver's seat is operated, and then the whole is worn in reverse, that is, the sunglasses on the lenses a are used, so that the front can be kept from being blurred and glare can be accommodated.

Further, if a wearable terminal mirror is used as the eyeglass a and a convex lens is used as the eyeglass B, the eyeglass B can be used as a presbyopic glasses, and can also be used as a wearable terminal mirror. When the wearable terminal mirror is used in a production line of a factory, items of confirmation work, specification contents, and the like are displayed, a product conforming to the specification can be assembled without fail at the time of assembly. Therefore, the product of the present invention is useful in various factories where a small amount of production is performed. In addition, if the product of the invention is distributed to audiences in a theater, and the introduction of the plot or the appearance characters and the explanation thereof are displayed on the wearable terminal mirror, more pleasure can be brought to the audiences, and the product becomes an effective means for catching the visitors.
