The present invention relates to a nose pad adjustment assembly, especially to a nose pad adjustment assembly which not only allows glasses to be worn and positioned without sliding freely but also provides more comfort to users while wearing the glasses. The nose pad adjustment assembly is more convenient to operate and more practical and effective to use.
Generally, various types of glasses are classified according to their functions or purposes such as optical glasses, sunglasses, sports glasses, and safety glasses. The respective types of glasses have different designs of frames. For example, full frame glasses feature on that lenses are surrounded and held in a frame, making them well-protected. Thus the full frame glasses are usually used in optical glasses with expensive lenses. As to half frame glasses, they are lighter than the full frame glasses. Thus most of casual sunglasses, sports glasses and safety glasses are half frame glasses so that users can feel easy and convenient during outdoor activities, sports or construction operations.
No matter what kind of glasses you wear, they are provided with a nose piece/pad located under a middle part of the glasses and used for leaning on users' nose bridge while they are wearing the glasses. The nose piece is not only used for positioning the glasses, but also providing more comfort to users who wear the glasses.
Although the above nose pad can achieve the expected functions while the users wear the glasses, it still has certain shortcomings while in use. The nose pad of glasses with plastic frames is integrally produced so that a height and an angle of the nose pad are fixed. Yet a height and a width of different user's nose bridge are quite different. Thereby the nose pad is unable to lean on two sides of the user's nose bridge properly and this further causes conditions such as easily sliding or inclining of the glasses and a shift of a focal point of the lens to occur.
Thus there is room for improvement and there is a need to provide a novel nose pad adjustment assembly which is more practical and effective to use.
Therefore, it is a primary object of the present invention to provide a nose pad adjustment assembly which allows users to move and adjust two nose pad blocks with respect to nose connection portions on two sides of a nose pad base according to different heights and widths of user's nose bridge for close fit of the nose pad blocks to two sides of the user's nose bridge. Thus glasses are worn and positioned firmly without sliding freely and the user feels more comfortable while wearing the glasses. The nose pad adjustment assembly is not only more convenient to operate but also more practical and effective to use.
In order to achieve the above object, a nose pad adjustment assembly according to the present invention includes a nose pad base and two nose pad blocks.
The nose pad base which is used to fix and connect with the glasses is provided with a recess portion formed on a middle of the nose pad base for leaning against the user's nose bridge, and two connection portions disposed on the nose pad base and located at two sides of the recess portion correspondingly. Each of the connection portions is provided with an upper locking hole and a lower locking hole.
Each of the nose pad blocks consists of an upper protrusion and a lower protrusion protruding from the nose pad block and respectively corresponding to the upper locking hole and the lower locking hole on the connection portion of the nose pad base. The upper protrusion and the lower protrusion are respectively able to be moved transversely within the upper locking hole and the lower locking hole and provided with a plurality of upper locking grooves and a plurality of lower locking grooves which are respectively able to be engaged and connected with the upper locking hole and the lower locking hole correspondingly.
Preferably, the nose pad base is integrally connected with either a frame or a lens of the glasses.
Preferably, an assembly portion is disposed on an upper end of the nose pad base for connection with the frame or the lens of the glasses.
Preferably, the nose pad block is made of soft material.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein:
In order to learn technical content, purposes and fnctions of the present invention more clearly and completely, please refer to the following detailed descriptions with the figures and reference signs.
Refer to
The nose pad base 1 can be integrally connected with either a frame or a lens of a pair of glasses 3. Or the nose pad base 1 is further provided with an assembly portion 11 on an upper end thereof for connection with the frame or the lens of the glasses 3. The nose pad base 1 is further provided with a recess portion 12 formed on a middle of the nose pad base 1 for leaning against user's nose bridge, and two connection portions 13 arranged at the nose pad base 1 and corresponding to two sides of the recess portion 12. Each of the connection portions 13 is provided with an upper locking hole 131 and a lower locking hole 132.
Each of the nose pad blocks 2 which is made of soft material consists of an upper protrusion 21 and a lower protrusion 22 protruding from the nose pad block 2 and respectively corresponding to the upper locking hole 131 and the lower locking hole 132 on the connection portion 13 of the nose pad base 1. The upper protrusion 21 and the lower protrusion 22 are respectively able to be moved transversely within the upper locking hole 131 and the lower locking hole 132 and provided with a plurality of upper locking grooves 211 and a plurality of lower locking grooves 221 which are respectively able to be engaged and connected with the upper locking hole 131 and the lower locking hole 132 correspondingly.
While in use, the upper protrusion 21 and the lower protrusion 22 of the nose pad block 2 are respectively inserted into the upper locking hole 131 and the lower locking hole 132 of the connection portion 13 of the nose pad base 1 and then engaged and connected with the upper locking hole 131 and the lower locking hole 132 correspondingly for positioning. When a user wears the glasses 3, the recess portion 12 on the middle of the nose pad base 1 is leaning against the user's nose bridge and then the upper and the lower protrusions 21, 22 of the nose pad block 2 within the upper and the lower locking holes 131, 132 of the connection portion 13 are moved and adjusted transversely in the same direction according to different heights and widths of the user's nose bridge. Refer to
In summary, the nose pad adjustment assembly according to the present invention allows users to move and adjust the nose pad blocks with respect to the nose connection portions on two sides of the nose pad base according to different heights and widths of the user's nose bridge for close fit of the nose pad blocks to two sides of the user's nose bridge. Thus the glasses are worn and positioned firmly without sliding freely and the user feels more comfortable while wearing the glasses. Therefore, the nose pad adjustment assembly is not only more convenient to operate but also more practical and effective to use.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalent.
