BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an eyeglass auxiliary part, and more particularly to a clip device for holding auxiliary eyeglasses.

2. Description of the Prior Art

In general, eyeglasses are fixed on an eyeglass frame. The eyeglasses can't be detached from the eyeglass frame without using a tool. Due to this structure, one pair of eyeglasses only has one function. Spectacles are categorized as spectacles for nearsightedness, spectacles for long sight, plain glass spectacles, sunglasses, and so on. These days, there are 3D spectacles for watching 3D image. In some occasions, people have to wear dual-function spectacles, such as spectacles for nearsightedness having a sunglasses effect. Some spectacles have the dual-function. However, they may be limited to the environment. For example, the spectacles for nearsightedness having a sunglasses effect are adapted for outdoor or a sunny day, not for indoor or a cloudy day.

In order to solve the aforesaid problem, auxiliary eyeglasses are mounted on a primary eyeglass frame. In order to have a convenient use, the auxiliary eyeglasses are provided with a fixing structure to couple the auxiliary eyeglasses on the primary eyeglass frame, without changing the original eyeglass frame.

FIG. 1andFIG. 2show a conventional clip structure for holding auxiliary eyeglasses. Through the clip structure1, the auxiliary eyeglasses2are clipped on a primary eyeglass frame (not shown in the drawings). The clip structure1comprises a fixing portion11, a main clip12, clip feet13, a resilient plate14, and a torsion spring15. The fixing portion11is adapted to fix two auxiliary eyeglasses2together, and includes a U-shaped main bridge111and two clip pieces112. Through the U-shaped main bridge111and the two clip pieces112, the auxiliary eyeglasses2are secured with rivets. The main clip12has two engaging troughs, one is for engaging with the main bridge111and the other is for engaging with the clip feet13. The main clip12has main clip feet121. The clip feet13are connected with a lateral bridge131which is engaged with one of the engaging troughs of the main clip12. The resilient plate14and the torsion spring15are fitted on the lateral bridge131. The torsion spring15has one foot engaged with the main clip12and another foot engaged with the resilient plate14. When in use, the resilient plate14is pressed to lift the clip feet13, such that the auxiliary eyeglasses are clipped on the primary eyeglass frame.

This clip structure has too many parts including the fixing portion11made of metal, the clip feet13, the resilient plate14, the torsion spring15, and the main clip12made of hard plastics. The rivets are required to connect the fixing portion11and the auxiliary eyeglasses2together. Each rivet needs to be punched alone. Therefore, the clip structure is complicated in manufacture and difficult in assembly and is not cost-effective. Besides, most of the clip structure is made of metallic materials, which needs spraying paint or electroplating to cause high cost.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a clip device for holding auxiliary eyeglasses, which can be assembled quickly and manufactured with ease to lower the cost.

In order to achieve the aforesaid object, a clip device for holding auxiliary eyeglasses includes a clip body and a retaining rivet plate. The clip body is made by injection molding and made of plastics material which has high elasticity and strong tenacity. The clip body includes a retaining portion, a resilient piece and two resilient clips. The retaining portion has a plurality of retaining holes thereon. The resilient piece is integrally formed with an upper end of the retaining portion. An upper end of each of the two resilient clips is integrally formed with an upper end of the resilient piece and protrudes outward to form a press portion. A lower end of each of the two resilient clips is a free end. The retaining rivet plate has a plurality of retaining pins. When assembling, the retaining pins of the retaining rivet plate are inserted through holes of the auxiliary eyeglasses and the retaining holes of the clip body. The retaining pins each have a distal portion exposed out of the retaining portions to be extruded and positioned thereon by hot melt.

Preferably, the retaining portion has a reverse U shape and the retaining rivet plate has a reverse U shape corresponding to the retaining portion.

Preferably, the retaining portion has two lateral bridges extending outward from two upper sides thereof and the retaining rivet plate has and two bridges extending outward from two upper sides thereof corresponding to the lateral bridges of the retaining portion.

Preferably, the clip body comprises one or more resilient pieces.

The clip device for holding auxiliary eyeglasses of the present invention is composed of two parts. The resilient clip can be lifted and pressed down by using its resilience. The clip body and the retaining rivet plate are fixed by melting a distal portion of the retaining pin. Therefore, the present invention can be assembled quickly and manufactured with ease to lower the cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 8andFIG. 9show a clip device for holding auxiliary eyeglasses according to a preferred embodiment of the present invention. Two auxiliary eyeglasses2are mounted on a primary eyeglass frame (not shown in the drawings) through the clip device. The clip device comprises a clip body8and a retaining rivet plate9.

As shown inFIG. 3andFIG. 4, the clip body8is made by injection molding and made of plastics material (memory plastics) which has high elasticity and strong tenacity. The clip body8comprises a retaining portion81, a resilient piece82, and a resilient clip83. The retaining portion81has a reverse U shape, a plurality of retaining holes811thereon, and two lateral bridges812extending outward from two upper sides thereof. The resilient piece82is integrally formed with an upper end of the retaining portion81. The present invention can includes one resilient piece or a plurality of resilient pieces. There are two resilient clips83in this embodiment. An upper end of each resilient clip83is integrally formed with an upper end of the resilient piece82and protrudes outward to form a press portion831. A lower end of each resilient clip83is a free end.

As shown inFIG. 5andFIG. 6, the retaining rivet plate9has a reverse U shape corresponding to the retaining portion81, a plurality of retaining pins91corresponding to the retaining holes811of the retaining portion81, and two bridges92extending outward from two upper sides thereof corresponding to the lateral bridges812of the retaining portion81.

To assemble the present invention, as shown inFIG. 7andFIG. 8, the retaining pins91of the retaining rivet plate9are inserted through the holes21of the auxiliary eyeglasses2and the retaining holes811of the clip body8, and then the retaining pins91each have a distal portion exposed out of the retaining portions81to be extruded and positioned thereon by hot melt, such that the auxiliary eyeglasses2are fixed on the clip device, as shown inFIG. 9.

When in use, as shown inFIG. 8, the press portion831is pressed downward to bend the resilient piece82, so that the free end of each resilient clip83is lifted for the auxiliary eyeglasses2to be clipped on the primary eyeglass frame. Through the sunshade or other function of the auxiliary eyeglasses, the auxiliary eyeglasses are clipped on the primary eyeglass frame to achieve a dual-function effect.
