The present invention relates to a detachable auxiliary eyeglasses used in general eyeglasses, and in particular, by using the shape memory effect and the superelastic effect of an elastic member made of a shape memory alloy, it is possible to combine or separate more quickly and simply and firmly A removable accessory glasses for use in the glasses.

In general, the wearer wears sunglasses to reduce eye strain or block ultraviolet rays when driving or being exposed to sunlight. Also, when using a computer, safety glasses are used to block electromagnetic waves. In this case, the wearer takes off glasses and wears sunglasses or goggles.

However, it would be quite convenient if the spectacle wearer could attach or detach the spectacles wearing auxiliary glasses such as sunglasses or goggles.

Hereinafter, in the present specification and claims, the glasses used for this purpose are referred to as 'auxiliary glasses', and the eyeglasses used for the auxiliary glasses may be used for vision correction or protection depending on the purpose.

6 is a perspective view of a conventional glasses and auxiliary glasses. As shown in FIG. 6, the general eyeglasses 100 typically have a pair of eyeglass frames for fixing each eyeglass, a corridor interconnecting each of the eyeglass frames so as to maintain a constant distance within the same plane, and an inner inner side of each eyeglass frame. It consists of a pair of nose rings and a pair of connecting legs connected to the outside of each of the spectacle frames. The auxiliary glasses 200 are attached to the upper and lower sides of the pair of spectacle frames 240 for fixing the eyeglasses 220, each of the corridors 260 and the spectacle frames 240, which are connected to each other in the same plane. Consisting of clips 280 and 290.

In the above-described configuration, the auxiliary glasses 200 are joined by fitting the clips 280 and 290 to the rim of the general glasses 100. However, such a detachable structure is considerably inconvenient in terms of use, and when excessive force is applied, the clips 280 and 290 are deformed or broken, and thus there is a problem in that coupling is impossible.

In addition, since the clips 280 and 290 are not coupled when they are longer or shorter than the length between the upper edge and the lower edge of the general glasses 100, the auxiliary glasses 200 may be separate according to the size or shape of the general glasses 100. There was a problem to use.

In addition, since the plurality of clips 280 and 290 are attached to the upper side and the lower side of the auxiliary spectacle frame 240, the edges of the auxiliary spectacle frame 240 are dirty and the glasses themselves become heavier, which causes a problem of poor fit.

As described above, the conventional auxiliary glasses 200 are inconvenient to use directly in a worn state and less compatible, and have a problem that the appearance is dirty and uncomfortable to wear.

The present invention has been made to solve the problems of the removable eyeglasses used in the conventional general eyeglasses described above, and its object is to provide a detachable auxiliary eyeglasses with a simple structure, a convenient detachable method, a good fit and a clean appearance. .

Hereinafter, the auxiliary glasses according to various embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, a shape memory alloy used as a material of an elastic member will be described.

When the shape is memorized at a certain temperature, the shape memory alloy is a shape memory effect that returns to its original shape when heated to the shape recovery temperature, and bends greatly at a temperature higher than the shape recovery temperature. It is an alloy with a super-elastic effect that returns to its original state when the power is removed.

The shape memory alloy is typically a nickel-titanium (Ni-Ti) alloy, a nickel-titanium-cobalt (Ni-Ti-Co) alloy or a nickel-titanium-copper (Ni-Ti-Cu) alloy, and is manufactured by heat treatment.

The shape memory alloy thus prepared has a superelasticity that is restored to its original form with respect to external forces, unlike ordinary metals in which residual strain or permanent strain occurs.

Examples 1 to 3

FIG. 1A is a perspective view illustrating an auxiliary glasses according to a first embodiment of the present invention, and FIG. 1B is a perspective view illustrating a state in which the auxiliary glasses of FIG. 1A are coupled to general glasses. Figure 2a is a perspective view showing a part of the auxiliary glasses modified from the first embodiment of the present invention, Figure 2b is a perspective view showing a state in which the auxiliary glasses of Figure 2a coupled to the normal glasses. FIG. 3A is a perspective view of the auxiliary glasses in which the first and second embodiments of the present invention are partially modified, and FIG. 3B is a perspective view illustrating a state in which the auxiliary glasses of FIG. 3A are coupled to general glasses.

The auxiliary glasses 20, 30 and 40 according to the first to third embodiments of the present invention are composed of a pair of eyeglass frames 24, elastic members 26, 36, 46 and a pair of locking members 28. do.

In the above configuration, the locking member 28 is fixed to each of the eyeglass frames 24 on the inner side near the shortest distance with respect to the same plane of each eyeglass frame 24. The elastic members 26, 36, 46 protrude outwardly in a '⊂' shape with respect to the same plane of each eyeglass frame 24 and are fixed to each of the eyeglass frames 24. However, the elastic member 26 of FIG. 1A is fixed at substantially the same position as the locking member 28, and the elastic member 36 of FIG. 2A is above the position of the locking member 28, and the elastic member 46 of FIG. ) Is fixed below the position of the locking member (28).

Hereinafter, the operation of the above-described configuration will be described.

In order to couple the auxiliary glasses 20, 30, and 40 to the general glasses 10, external force is first applied to the elastic members 26, 36, and 46. The elastic members 26, 36 and 46 are deformed by the external force and the spectacle frame 24 is closed by moving. The locking member 28 is closed by the distance that the spectacle frame 24 is moved. The retracted locking member 28 is inserted into the general glasses 10 as shown in FIGS. 1B, 2B and 3B. When the external force is removed after insertion, the spectacle frame 24 is opened again by the restoring force of the elastic members 26, 36, and 46, and at the same time, the latching member 28 is also opened, and the spectacle frame 24 is placed under the nose leg of the general glasses 10. ) Will get caught in each. Thus, the auxiliary glasses 20, 30, 40 are coupled to the normal glasses 10.

Unlike the aforementioned combination, the separation process is the same as that of the bonding except that the auxiliary glasses 20, 30, and 40 are inserted in the opposite direction.

Example 4

4A is a rear view illustrating the auxiliary glasses according to the fourth embodiment of the present invention, and FIG. 4B is a perspective view illustrating a state in which the auxiliary glasses of FIG. 4A are coupled to general glasses.

The construction and operation of the auxiliary glasses 50 according to the fourth embodiment are similar to those of the auxiliary glasses 20, 30 and 40 of the first to third embodiments described above. However, unlike the elastic members 26, 36, 46 of the first to third embodiments, the elastic members 56 of FIGS. 4A and 4B are concave in the middle in the same direction as the same plane of each eyeglass frame 24. 4A and 4B, the elastic member 56 has an 'omega' shape almost similar to the parabolic shape. Of course, in Embodiments 1 to 3, an elastic member having such a shape can be used.

In addition, the position where the locking member 58 is attached to the general glasses 10 is different from the first to third embodiments described above. That is, as illustrated in FIG. 4B, the locking member 58 is attached to each of the eyeglass frames 24 so as to be caught above the nose leg of the general eyeglasses 10.

Example 5

5A is a rear view of the auxiliary glasses according to the fifth embodiment of the present invention, and FIG. 5B is a perspective view illustrating a state in which the auxiliary glasses of FIG. 5A are coupled to general glasses.

The fifth embodiment is similar to the configuration and operation of the fourth embodiment described above, but as shown in Figs. 5A and 5B, the engaging members 68 and 69 are composed of two pairs (four in total), and the general glasses ( 10) is paired to each of the upper and lower eyeglass frames 24 to the border of the nose leg. This structure can more reliably prevent the fall of the auxiliary glasses 60 according to the shape of the general eyeglasses 10. Of course, in the embodiments 1 to 4 such a locking member can be used.

In addition, both pairs of engaging members 68 and 69 may be attached to each of the spectacle frames above or below the nose leg of the generic spectacles 10, not shown.

Example 6

The elastic members of Embodiments 1 to 5 described above use the shape memory alloy as described above. However, ordinary alloys having elasticity have a problem in that they frequently return to their original form, such as shape memory alloys, and even become permanently deformed or broken when used frequently.

Accordingly, when the elastic member of the present invention is used, residual deformation or permanent deformation due to frequent external force does not occur, and thus it can be used in vante glasses and frameless glasses that are always fragile by providing a constant elastic force.

Example 7

The elastic members of the above-described embodiments 1 to 5 use a shape memory alloy regardless of its shape, but if the elastic member is made of stainless steel to have a parabolic shape, ie, an omega (Ω) shape, which is recessed in the middle, an elastic member having a different shape More elastic force can be used as a material of the elastic member of the present invention.

As described above, the present invention is not limited to the above-described various embodiments and may be variously modified within the range allowed by the technical idea of the present invention. For example, since the mutual distance of the general eyeglasses to which the locking member of the auxiliary eyeglasses is attached or detached is constant regardless of the shape or size thereof, the auxiliary eyeglasses of the present invention can be easily attached and detached to all the general eyeglasses. Although the spectacle frame is shown in a circle in the drawing, the shape of the spectacle frame may be any shape as long as the structure accommodates the eyeglasses.

In addition, as long as it can be applied to an external force on the elastic member of the present invention or coupled to the general glasses of the locking member, the shape, position or number can be variously implemented.

In addition, although the auxiliary glasses of the present invention are fixed to the elastic frame and the locking member to the eyeglass frame, respectively, when the polyamide material is used, the auxiliary glasses can be integrally injection molded.

According to the detachable auxiliary glasses of the present invention as described above, the auxiliary glasses can be easily coupled to or separated from ordinary glasses by external force, and can be used for all glasses. In addition, since the elastic member uses an elastic member that is not permanently deformed, the auxiliary glasses have an effect that is surely coupled to the ordinary glasses.

In addition, the auxiliary glasses of the present invention have a good fit and reduce appearance by reducing the weight due to the simple structure of the locking member.
