BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to an eyeglass frame made of a material which is extremely difficult to work, for example, an NT alloy (shape memory alloy).
2. Background Art
A conventional eyeglass frame of this type is shown as an eyeglass frame 100 in FIG. 5 (Japanese Standards Association, Terminology of Eyeglasses, page 8, issued on Apr. 1, 1987). The eyeglass frame 100 comprises a pair of right and left rims 102 which support right and left eyeglass lenses 101, respectively. The pair of right and left rims 102 is connected by a bridge 103. To reinforce the connection between the rims 102 provided by the bridge 103, a brace bar 104 is disposed above the bridge 103 to connect the top portions of the pair of right and left rims 102.
A pair of pads 107 which is supported by the nose of a user is mounted on the inner sides of the respective left and right rims 103. Reference numeral 105 denotes a side joint which serves as a hinge, and a temple 106 is pivotally secured to the side joint 105.
The eyeglass frame 100 having the above-described arrangement needs a considerable number of parts since the side joints 105 are formed on the outer portions of the respective rims 2 and the temples 106 are secured to the respective side joints 105. In particular, in the case of eyeglass frames employing an NT alloy material, since NT alloy materials are difficult to solder, conventional connecting tools and special connecting tools are needed to bond the NT alloy members to the outer peripheries of the respective rims.
In addition, the manufacturing process needs the step of connecting the rims 102 by means of the bridge 103 and securing the temples 106 to the respective side joints 105.
DISCLOSURE OF THE INVENTION
The object of the present invention is to solve the above-described problems experienced with the prior art. In an eyeglass frame comprising rims for supporting a pair of right and left eyeglass lenses, a bar disposed between the upper portions of the respective rims so as to connect the rims, and temples secured to the bar of eyeglasses, first engagement tubes are secured to opposite ends of the bar, and second tubes are secured to the securing ends of the respective temples. The first engagement tubes secured to the opposite ends of the bar are fixedly connected to the corresponding second engagement tubes secured to the mounting ends of the respective temples, and the first engagement tubes are secured to the respective rims. With the above-described arrangement, the number of parts required to secure the temples to the rims can be reduced. In addition, since the temples are connected to the opposite ends of the bar and the bar is then secured to the upper portions of the respective rims, it is possible to reduce the number of steps in a manufacturing process.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of an eyeglass frame according to the present invention;
FIG. 2 is a perspective view of the connection between a bard and a temple in the eyeglass frame according to the present invention;
FIG. 3 is a plan view of the connection between the bar and the temple;
FIG. 4 is a front view of the connection between the bar and the temple; and
FIG. 5 shows an eyeglass frame according to a prior art, and Part 5 (A) is a front view of the eyeglass frame, while Part 5 (B) is a side view of the same.
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of an eyeglass frame, and the eyeglass frame according to the present invention is indicated generally at 1. The eyeglass frame 1 comprises rims 3 for supporting right and left eyeglass lenses 2, respectively.
A bar 4 is disposed above the rims 3 and the bar 4 and the rims 3 are connected to each other. The connection between the bar 4 and the rims 3 is accomplished by securing engagement tubes 5 made of nickel silver or the like to the opposite ends of the bar 4 and pinching the first e
