Patent Application
20170184873
This application claims priority to Chinese Patent Application No. 201510978779.9 filed on Dec. 24, 2015, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to design and construction of eyeglasses, and particularly to eyeglasses and a nose pad assembly of the eyeglasses.
Eyeglasses include a nose pad assembly and a frame, usually, the nose pad assembly and the frame are integrated, or the nose pad assembly is welded on the frame.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the exemplary embodiments described herein. However, it will be understood by those of ordinary skill in the art that the exemplary embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the exemplary embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
The present disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. Several definitions that apply throughout this disclosure will now be presented. It should be noted that references to “an” or “one” exemplary embodiment in this disclosure are not necessarily to the same exemplary embodiment, and such references mean “at least one”.
Exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.

Referring to
The receiving member 12 defines a receiving space which is used for receiving the bracket 11. A shape of the receiving member 12 is the same as the shape of the bracket 11, that is, the receiving member 12 is also inverted U-shaped. The receiving member 12 includes a connecting member 120 and two nose pads 121. The nose pads 121 are fixed on each end of the connecting member 120. The connecting member 120 defines at least one through hole 122 at a position corresponding to the screw hole 115 of the fixing member 110. In the illustrated exemplary embodiment, the connecting member 120 defines two through holes 122. The connecting member 120 receives the fixing member 110 of the bracket 11, the nose pad 121 receives the supporting member 111 of the bracket 11, and the through hole 122 is aligned with the screw hole 115. In the illustrated exemplary embodiment, the receiving member 12 is made from rubber or similar material.
As illustrated in
When a user needs to adjust an optical distance between the eyeglasses 1 and eyes of the user, the user can apply force to move the two nose pads 121. The force can be applied simultaneously on the lower part 114 of the supporting member 111. The shape of the middle part 113 of the supporting member 111 allows only a light force to be sufficient to drive the two supporting members 111 closer together or further away from each other, thereby a distance between the two nose pads 121 is changed, and accordingly the optical distance between the eyeglasses 1 and the eyes of the user is adjusted. In addition, the supporting member 111 can also be driven to rotate easily by the light force, which enables the two nose pads 121 to be adapted to the shape of the user's nose.
In the illustrated exemplary embodiment, a length of the upper part 112 of the supporting member 111 is less than a length of the middle part 113, and a length of the lower part 114 is greater than the length of the middle part 113. Thus, the extent of the force to be applied on the nose pad 121 to achieve a desired fitting is reduced even further, as the lower part 114, the middle part 113 and the upper part 112 can be easily driven to move or deform.
A torque of the middle part 113 is in proportion to the length of the lower part 114, that is, the longer the lower part 114 is, the more easily the middle part 113 deforms, thus, if the length of the lower part 114 is greater than the length of the middle part 113, the user can adjust the distance between the eyeglasses 1 and the eyes more easily. A bending moment of the upper part 112 is in proportion to the length of the upper part 112, that is, the longer the upper part 112 is, the more easily the upper part 112 bends. Thus, if the length of the upper part 112 of the supporting member 111 is less than the length of the middle part 113, the upper part 112 is relatively short and cannot be easily broken, thereby avoiding damage to the bracket 11 when adjusting the distance between the eyeglasses 1 and the eyes of the user.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being exemplary embodiments of the present disclosure.
