This Non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No(s). 092212281 filed in Taiwan on Jul. 3, 2003, the entire contents of which are hereby incorporated by reference.
1. Field of the Invention
The present invention relates generally to an eyeglass device, and more particularly to a magnetically combined eyeglass device, which is structurally secured to avoid accidental detachment and is simple for assembly.
2. Description of the Related Art
A conventional eyeglass device as disclosed in U.S. Pat. No. 6,412,942 is comprised of a primary frame and an auxiliary frame attached magnetically to the primary frame. The primary frame used as common eyeglass device includes two rims, two lenses embedded respectively into the two rims, and two temples mounted at two lateral sides of the rims. The auxiliary frame includes two rims and two lenses, being magnetically attached to a front side of the primary frame in a specific condition for blinding strong light or for other additional usage. Each of the rims of the primary and auxiliary frames is made of a material, which is magnetic either itself or is attractable by magnetism. Accordingly, the primary and auxiliary frames can be magnetically combined together rather than conventional mechanical connecting manners, such as coupling and engagement, such that the eyeglass device is convenient for use.
However, the conventional eyeglass device still includes four drawbacks as follows.
1. Because each of the rims of the primary and auxiliary frames is of radian in appearance, the rim is subject to deformation caused by improper use, and further, the primary and auxiliary frames may frequently fail to be tightly attached with each other and may even cause their accidental detachment.
2. The scope of applications of such eyeglass device is limited, e.g. it fails to be applied to currently popular rimless eyeglass device.
3. Because the rims of such eyeglass device are made of materials, which are magnetic themselves or attractable by magnetism, the production cost is high and such materials are not diversified but limited.
4. Such eyeglass device has to be completely finished at the time of production and fail to be further processed by the retainers or the users subject to their requirement, thereby being inflexible for use.
The primary objective of the present invention is to provide a magnetically combined eyeglass device, which is structurally secured to avoid accidental detachment.
The other objective of the present invention is to provide a magnetically combined eyeglass device, which is applicable to rimless, semi-rim, and full-rim eyeglass devices.
Another objective of the present invention is to provide a magnetically combined eyeglass device, which is flexible for simple assembly subject to the requirement of the retainer or user.
The foregoing objectives of the present invention are attained by the eyeglass device, which is comprised of a primary frame and an auxiliary frame. The primary frame includes a bridge, two brow portions extending outwards respectively from two ends of the bridge, two temples extending rearwards respectively from two distal ends of the brow portions, and two primary magnetic members disposed respectively on the two brow portions. Each of the primary magnetic members has a magnetic surface facing upwards or downwards or rearwards. The auxiliary frame includes a bridge, two brow portions extending outwards respectively from two ends of the bridge, and two auxiliary magnetic members disposed respectively on the two brow portions. Each of two auxiliary magnetic members has a magnetic surface corresponding to the magnetic surface of the primary magnetic member of the primary frame. Accordingly, the two magnetic surfaces of the primary and auxiliary magnetic members can be magnetically attachable to each other, such that the primary and auxiliary frames are securely magnetically combined together.
Alternatively, the eyeglass device provided by the present invention is comprised of two primary lenses, a bridge connected between the two primary lenses, two temples mounted respectively on two ends of the two primary lenses, two primary magnetic members disposed respectively on top edges of the two primary lenses respectively by their primary props, two auxiliary lenses interconnected together by a bridge, and two auxiliary magnetic members disposed on top edges of the two auxiliary lenses respectively by their auxiliary props to be magnetically attached with the two primary magnetic members.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
Referring to
The primary frame 11 includes a bridge 12, two brow portions 13 extending outwards respectively from two ends of the bridge 12, two lenses 131 connected respectively below the two brow portions 13, two temples 14 extending rearwards respectively from two distal ends of the brow portions 13, and two primary magnetic members 15 disposed respectively on the two brow portions 13 by two props 151. Each of the two props 151 extends rearwards from the two brow portions 13. Each of the two primary magnetic members 15 has a magnetic surface 152 facing upwards.
The auxiliary frame 16 includes a bridge 17, two brow portions 18 extending outwards respectively integrally from two ends of the bridge 17, two lenses 181 connected respectively below the two brow portions 18, and two auxiliary magnetic members 19 disposed on the two brow portions 18 by two props 191. Each of the two props 191 extends rearwards from the two brow portions 18. Each of the two auxiliary members 19 has a magnetic surface 192 facing downwards and corresponding to the magnetic surface 152 of the primary magnetic members 15.
The primary and auxiliary magnetic members 15 and 19 are made of magnetic materials, such that the magnetic surfaces 152 and 192 are magnetically attachable to each other to magnetically combine the primary frame 11 and the auxiliary frame 16 together. Because the primary and auxiliary magnetic members 15 and 19 are combined together two-point by two-point, even if the two frames 11 and 16 are deformed for long time of use, as long as the primary and auxiliary magnetic members 15 and 19 are magnetically attractable, the two frames 11 and 16 can still be securely combined together. In addition, the two frames 11 and 16 can be made of any proper materials, not such limited like the prior art, and reduce the production cost.
It is to be noted that both of the primary and auxiliary magnetic members 15 and 19 are not necessarily made of magnetic materials, i.e. either one of them is made of a magnetic material and the other can be made of a material, which can be made of any material attractable by magnetism, such as iron or alloy or plastic. Besides, the magnetic member and the prop may be formed in one piece; that is, the prop itself may be made of magnetic materials.
Further, the arrangement of the primary and auxiliary frames and the props can be diversified. Referring to

As a matter of fact, only if the primary and auxiliary magnetic members, which are disposed respectively on the brow portions, are magnetically attractable to each other, no matter how the types of the eyeglass device are diversified is included within the claimed scope of the present invention. In addition, the primary and auxiliary magnetic members can be directly inlaid into the brow portions of the primary and auxiliary frames and merely enable the corresponding magnetic surfaces to be exposed outside for being mutually magnetically attached with each other.
