## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an eyeglasses assembly including main eyeglasses and auxiliary eyeglasses combined with each other.
2. Background of the Related Art
Many combination methods for combining main eyeglasses with auxiliary eyeglasses have been disclosed and developed to date. The inventor of the present invention has a number of patent applications and patent rights related to eyeglasses having auxiliary eyeglasses. In general, the main eyeglasses and the auxiliary eyeglasses are directly combined with each other using magnets or hooks.
However, the direct combination of the main eyeglasses with the auxiliary eyeglasses has several disadvantages. Specifically, their structure is complicated as both of the main eyeglasses and auxiliary eyeglasses must have various components for the direct combination, and they are inconvenient to use as the main eyeglasses and the auxiliary eyeglasses have the connecting components even in a state in which the combination of the main eyeglasses with the auxiliary eyeglasses is not needed.
There is therefore an urgent need for an eyeglasses assembly having main eyeglasses and auxiliary eyeglasses, which can be simply used with or without the separate components for the combination so that the user may wear only the main eyeglasses, or may wear both the main and auxiliary eyeglasses which can be easily combined with each other.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been made in view of the above-mentioned problems and it is an object to provide an eyeglasses assembly in which a connection bar is interposed between main eyeglasses and auxiliary eyeglasses, so that the main eyeglasses can be selectively combined with the auxiliary eyeglasses via the connection bar.
The eyeglasses assembly can be easily assembled and disassembled and be easily opened in front according to a change of surrounding environment and the user's mood or feeling when using existing sunglasses or other eyeglasses having auxiliary eyeglasses. The connection bar is detachably mounted to the upper portions of the lens rims of the main eyeglasses in a horizontal position using various means such as magnets, pins, and so on, and then, is coupled with the auxiliary eyeglasses, so that the auxiliary eyeglasses are combined with the main eyeglasses according to the user's intended use.
According to the eyeglasses assembly, when the combination of the auxiliary eyeglasses with the main eyeglasses is desired, the main eyeglasses and the auxiliary eyeglasses are combined with each other via the connection bar. Upon removal of the auxiliary eyeglasses from the main eyeglasses, the main eyeglasses may be used alone, or may provide a beautiful outward appearance by mounting only the fashionable connection bar thereon without using the auxiliary eyeglasses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
The structure and function of an eyeglasses assembly in which main eyeglasses are combined with auxiliary eyeglasses via a connection bar will now be described in detail.
As shown in FIGS. 1A, 1B, and 1C, the present invention includes main eyeglasses 1, auxiliary eyeglasses 100, and a connection bar 50.
The main eyeglasses 1 have the shape of conventional eyeglasses including a main lens frame having a pair of lens rims 2 holding a pair of main lenses which are interconnected via a nose piece 3, also called a “bridge”.
The auxiliary eyeglasses 100 include an auxiliary lens frame which has an adjacent pair of lens rims 102 holding a pair of auxiliary lenses and a nose piece 103 for interconnecting the uppermost portions of the lens rims 102. The nose piece 103 is generally called a topbar.
The lens rims 2 of the main eyeglasses 1 have connection bar seating portions 5 formed on the upper portions thereof for seating the connection bar 50 on the upper surfaces of the lens rims 2.
The connection bar 50, which may have a curved or straight construction, includes main eyeglass seating portions 51 formed at both sides thereof and an auxiliary eyeglass seating portion 52 formed at the center of the inner surface thereof. The combination of the main eyeglasses 1 with the auxiliary eyeglasses 100 can be made by any one of several known combination methods. For example, the seating portions 5, 51, 52 may have complementary pins and holes or locking jaws and hooks for joining the auxiliary eyeglasses 100 with the main eyeglasses 1. In the preferred embodiment according to the present invention, the connection bar 50 is detachably mounted on the main eyeglasses by a combination method using magnets.
As shown in FIGS. 2A through 3C, the connection bar 50 has a length corresponding to a distance between the connection bar seating portions 5 of the main eyeglasses 1, and has magnets 51′ inserted into the main eyeglass seating portions 51 at positions corresponding to the connection bar seating portions 5 of the main eyeglasses 1, and magnets 52′ inserted into the auxiliary eyeglass seating portion 52 at positions corresponding to the nose piece 103 which acts as the connection bar seating portion of the auxiliary eyeglasses 100. Finally, the main eyeglasses 1 and the auxiliary eyeglasses 100 are combined with each other by the attraction of the magnets 51′ and 52′ located to align with the corresponding positions of the connection bar seating portions 5 and nose piece 103, respectively. The joining of the main eyeglasses with the auxiliary eyeglasses by the connection bar 50 using the magnetic force of the magnets 51′ and 52′ can be accomplished by inserting the magnets 51′ and 52′ in the corresponding positions as described above. Alternatively, the whole connection bar 50 may be made of a magnetic material, and the connection bar seating portions 5 and nose piece 103 may be made of a material reacting to the magnetic material of the connection bar 50.
The auxiliary eyeglasses 100 have the lens rims 102, and the connection bar seating portion of the nose piece 103 for horizontally interconnecting the upper portions of the lens rims 102. An operative aspect of the present invention will now be described with reference to Korean Patent Application No. 10-2001-0075081 entitled “eyeglasses having auxiliary glasses, which are easily detachable and opened in front using magnets”, which has been filed and published in the name of the same inventor as the present invention, and is hereby incorporated by reference in its entirety.
As set forth therein, the auxiliary eyeglasses 100 may have a ‘’ or ‘’ shaped nose piece 103, as seen from the sides, and the nose piece 103 connects the lens rims 102 with each other. The nose piece 103 of the auxiliary eyeglasses has two contacting surfaces made of a material reactive to magnetic force to correspond to and cover the auxiliary eyeglass seating portion 52 of the connection bar 50. Therefore, through assembly of the auxiliary eyeglass seating portion 52 of the connection bar 50 and the nose piece of the auxiliary eyeglasses 100 in contact with the connection bar 50, the combined eyeglasses can be kept in an opened or “lifted-up” in-use condition, or in a closed or “down” in-use state by lifting up or folding down the auxiliary eyeglasses 100 from the connection bar 50, respectively. Of course, the lens rims 102 of the auxiliary eyeglasses 100, which are horizontally connected at the upper portions thereof, may be in a single form to keep only the assembly and disassembly states.
Referring to FIGS. 2A–2C and FIGS. 3A–3C, the assembly process of the eyeglasses combination according to the present invention will be described in more detail.
First, as depicted in FIGS. 2A and 3A, the main eyeglass seating portions 51 of the magnetic connection bar 50 are correspondingly put on the connection bar seating portions 5 formed on the upper portions of the lens rims 2 of the main eyeglasses 1 so as to join them with each other by the magnetic force.
Next, as shown in FIGS. 2B and 3B, the connection bar seating portion formed at the nose piece 103 for interconnecting the upper portions of the lens rims of the auxiliary eyeglasses 100 is correspondingly joined to the auxiliary eyeglass seating portion 52 formed at the center of the connection bar 50, which horizontally connects and is fixedly attached to the upper portions of the lens rims 2 of the main eyeglasses 1. By the above steps, the auxiliary eyeglasses 100 can be combined with the main eyeglasses 1, shown fully assembled in FIGS. 2C and 3C.
Positions of eyeglass use are shown in FIGS. 4 to 8. First, as shown in FIG. 4, the connection bar 50 is detachably mounted on the main eyeglasses 1. Next, as shown in FIG. 5, the connection bar seating portion of the nose piece 103 of the auxiliary eyeglasses 100, which has the ‘’ or ‘’ shaped section and has an opened contact surface and a closed contact surface, is closely attached to the auxiliary eyeglass seating portion 52 of the connection bar 50 by magnetic force while overlying the auxiliary eyeglass seating portion 52. After that, the opened contact surface and the closed contact surface of the nose piece, which are made of a magnetically reactive material, are selectively joined by lifting the auxiliary eyeglasses 100 up and down from the connection bar 50, so that the auxiliary eyeglasses can be kept in opened or closed states. The lifted-up in-use position of the auxiliary eyeglasses 100 is shown in FIG. 6. Top and front views of the assembled eyeglasses in the down in-use position are provided in FIGS. 7 and 8, respectively.
As set forth above, with the eyeglasses assembly according to the present invention, a user can selectively combine the auxiliary eyeglasses 100 with the main eyeglasses 2 via the connection bar 50, and when the auxiliary eyeglasses 100 are not needed, the user can wear only the main eyeglasses 1 with or without the connection bar for combining the auxiliary eyeglasses 100. Therefore, the present invention gives the user greater convenience in use as well as a fashion option conforming with the modern desirability of attaining a double bridge effect of eyeglasses by mounting only the connection bar 50 to the main eyeglasses 1.
While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
