BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to spectacles, and more particularly to a rimless spectacles, wherein a plurality of coupling slots are located at the lenses to engage with the temples and the bridge, so as to allow the lenses to be quickly fastened on the temples and the bridge to form an entire body structure of the rimless spectacles.

2. Description of Related Arts

Corrective lens have been existed in human history for a long time. People have used corrective lens to modify the focal length of the eyes and the corrective lens have gradually evolved to wearable glasses. Wearable glasses have been more widely used in modern society. Conventional glasses comprise a lens unit mounted at a frame unit. The frame unit usually comprises a frame, two temples and a bridge. Traditionally, the frame, the temples and the bridge are made integrally to form the frame unit. In other words, the frame, the temples and the bridge are all connected altogether in conventional spectacles, wherein each temple is fastened by a screw to an outer side of the frame.

The main purpose for people to wear spectacles is to correct vision or protect the eyes. Also, since spectacles are usually placed on the faces of people, people have even higher demands on the aesthetic value of the spectacles. As illustrated above, the frame is an indispensable component of the spectacles and the frame is usually adapted to secure the lens unit. Also, the conventional frame of the spectacles is usually made of metal materials or other stiff materials. So, when people wear spectacles, existence of the spectacle frame usually change the person's appearance on the face which is also a shortcoming of conventional spectacles.

With development of the society, more and more varieties extend from the conventional spectacles, such as rimless spectacles. Structurally, the rimless spectacles comprise lenses, temples, and a bridge directly connecting two lenses, wherein more than one connection holes are on each lens, such that the temples and the bridge are connected at the connection holes respectively. Generally speaking, the lens is made by glass materials, especially for near-sighted and farsighted spectacles. Furthermore, the thickness of the lens in the middle is different from that on the side. In other words, the surface of the lens of either near-sighted or farsighted spectacles is not a flat surface, and the difficulty of drilling holes thereon is thus increased. Normally, when drilling the holes on an object, the drilling device has to be perpendicular to the surface to be drilled to achieve the best drilling effect. In addition, the stiffness of glass materials is high and drilling holes thereon is likely to cause the glass material to break.

In addition, the tolerance of the hole must be considered. If the hole is too big, the lens will be unstable after the temples and the bridge are mounted thereto. If the hole is too small, the temples and the bridge cannot be affixed thereto. Or the lens will be cracked when the temples and the bridge are forced to affix to the lens.

With the difficulty in drilling holes on the lens mention above, it is inconvenient for customers to purchase rimless spectacles because when one chooses his or her own rimless spectacles, the lenses and the spectacle frame are separately chosen by the customer and put together by a technician. Because of the difficulty in drilling holes on an uneven lens surface, the technician usually takes longer time to put the lenses and the spectacle frame together. In other words, the customer has to wait for a long time from choosing the spectacles to actually receiving the final product.

Improved rimless spectacles are found in the market that the rimless spectacles do not require any hole predrilled on the lens. The lens has a notch pre-formed at the peripheral edge to fit a core-wire at the notch. Therefore, the temples and the bridge can be mounted to the lenses through the wires. However, such rimless spectacles can be made only in particular styles of lenses and the assembling operation is relatively complicated.

When the second connector30is placed at the coupling slot20of the lens10, the second connector30is fastened thereat via the locking panel321and the locking unit322. In other words, after the retention inserter311is slidably inserted into the coupling groove25at the front side11of the respective lens10, the locking panel321is slidably biased against the biasing surface3112through the coupling inserter312at the rear side12of the lens10, such that the locking unit322is locked at the coupling inserter312to form a secured locking structure between the first and second connectors20,30. Therefore, the locking structures of the first and second connectors20,30achieve the goal of fast and firmly connecting the temple units2and the bridge3with the lenses10to form the entire body rimless structure of the spectacles, as shown inFIG. 1.

Since the coupling slot20in the present invention is continuous channel defined by two opening edges21which are inwardly extended, such that it is unnecessary to drill any hole on the lenses10in the present invention. Technicians can easily cut at the peripheral edge13inwardly to form two side surfaces22and the arc surface23to form the coupling slot20.

As shown inFIGS. 5 to 8, the rimless spectacles of a second embodiment illustrate an alternative mode of the first embodiment of the present invention. Accordingly, the distance between the two side surfaces22equals to the width of the opening211. In other words, the two side surfaces22are extended in a parallel manner. Each of the second connectors30A comprises a connecting member31A and a clipping member32A, wherein the connecting members31A are provided at the temple units2and the bridge3respectively. Each of the connecting members31A comprises a retention inserter311A and a coupling shaft312A, wherein the retention inserter311A has a shape and size corresponding to the shape and size of the respective coupling slot25. Each of the retention inserters311A has a retention surface3111A and a biasing surface3112A, wherein the retention surface3111A is shaped and sized corresponding to the curved contacting surface24. When the retention inserter311A is slidably inserted into the corresponding coupling slot20inwardly from the peripheral edge13of the lens10, the retention surface3111A of the retention inserter311A is biased against the curved contacting surface24to securely retain the second connector30A at the predetermined location of the respective lens10.

Accordingly, the coupling shaft312A is coupled with the retention inserter311A. More specifically, the coupling shaft312A is coupled with the retention inserter311A to bias against the biasing surface3112A thereof.

The clipping member32A is pivotally engaged with connecting member31A, wherein the clipping member32A comprises a pressuring clipper321A and a trigger322A. The pressuring clipper321A is pivotally coupled with the coupling shaft312A of the connecting member31A while the trigger322A is extended from the pressuring clipper321A. When the connecting member31A of the second connector30A is slidably inserted into the coupling slot20at the peripheral edge13of the lens10, the trigger322A is actuated to pivotally move the pressuring clipper321A to bias against the biasing surface3112A at the rear side12of the lens10such that temple units2and the bridge3can be quickly and firmly engaged with the lenses10by the clipping force.
