## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The instant disclosure relates to an eyewear; in particular, to an adjustable nose pad structure for eyewear.
2. Description of Related Art
Conventional nose pads for eyewear are made of two pads respectively arranged on two sides of the frame near the center frontal portion of the eyewear either through two metal wires connected to the frame of the eyewear or an integrally formed body. The nose pads are configured to conform to the shape of a user's nose in order to reduce the pressure induced by the nose pads onto the nose. However, since the two metal wires are prone to deform due to external impact forces, the corresponding positions of the two nose pads tend to shift such that the nose pads cannot conform to the user's nose, and renders discomfort to the user. And the corresponding positions of the nose pads tend to awkwardly tilt with respect to the eyewear, thus, making it difficult to provide a clear and stable vision. If the degree of deformation on the metal wire is small, the metal wire can still be recovered with the proper tools. However, after repeated repairing, the strength of the metal wire significantly reduces.
Since the integrally formed nose pads overcome the awkward tilting due to external impact, the majority of protective eyewear adopts the integrally formed nose pads along with a closed frame for eye protection. As a result, workers can wear protective eyewear to prevent foreign objects from effecting workers' eyes. However, since the protective eyewear can be shared among various workers, the integrally formed nose pads will not conform to the various shapes and sizes of all workers' noses. As a result, the nose pads cause discomfort, or even scratching, swelling, and etc. among workers, which significant affects performance.
To address the above issues, the inventor strives via associated experience and research to present the instant disclosure, which can effectively improve the limitation described above.
SUMMARY OF THE INVENTION
The object of the instant disclosure is to provide an adjustable nose pad structure for eyewear in order to improve upon the non-adjustable nose pad.
In order to achieve the aforementioned objects, according to an embodiment of the instant disclosure, an adjustable nose pad structure includes
Translated after proofread
The instant disclosure has the following improvements. Via the adjustable engagement between the protrusions of the adjustable member and the recesses of the main body, the angles of two adjustable members can be adjusted according to the various sizes and shapes of users' noses. As a result, the two adjustable members can completely fit onto a user's nose, which provides more preferable comfort, fit and stability. The left and right adjustable nose pad structures of the instant disclosure are independent structures such that more special shapes and sizes of users' noses can be conformed to.
In order to further understand the instant disclosure, the following embodiments and illustrations are provided. However, the detailed description and drawings are merely illustrative of the disclosure, rather than limiting the scope being defined by the appended claims and equivalents thereof.

The two adjustable members 20 of the instant disclosure are adjustable structures through which nose pads can be adjusted. In other words, the conventional elastic nose pads can be installed (such as sleeved, adhered, clamped, or latched) on the adjustable nose pad structure 1 of the instant disclosure through the adjustable member 20 such that nose pads can be adjusted. In addition, in another embodiment, portions of the adjustable members 20 can be made of elastic and soft materials and directly serve as the nose pads directly making contact with a user's nose.
As shown in FIG. 1, the main body 10 is a U-shaped structure. Each of the two arms of the U-shaped structure includes an adjustable portion 11. Namely, the main body 10 may resemble various shapes according to the preferred design of the eyewear. For example the main body 10 may resemble the shape of a V or other shapes similar to U or V. Although U-shape is used as example in the figures, the instant disclosure is not limited herein. The adjustable portion 11 has portions defining an open slot 111 and a groove 112. The open slot 111 has two oppositely faced sidewalls. One of the sidewall has a plurality of first recesses 1111 and the other sidewall has a plurality of second recesses 1112. The plurality of first recess 1111 in the instant embodiment is a row of arced grooves, and the plurality of second recesses 1112 resembles a similar structure as the plurality of first recesses 1111.
The adjustable member 20 is correspondingly disposed in each adjustable portion 11. Each adjustable member 20 includes a pivotable portion 201 and a connecting body 202. The pivotable portion 201 and the connecting body 202 are mutually connected. Preferably, a rotational axis of the pivotable portion 201 is normal to a center line of the connecting body 202 along whose lengthwise direction. In other words, the pivotable portion 201 and the connecting body 202 form a T-shaped structure in the instant embodiment, in which the T-shaped structure can be an integrally formed structure. The connecting body 202 has two sidewalls, in which one of the sidewall has a first protrusion 2021 and the other sidewall has a second protrusion 2022. The shape of the first protrusion 2021 corresponds to the shapes of the first recesses 1111, whereas the shape of the second protrusion 2022 corresponds to the shapes of the second recesses 1112. Consequently, the first protrusion 2021 and the second protrusion 2022 can respectively engage to one of the first recesses 1111 and one of the second recesses 1112. Preferably, the first protrusion 2021 and the second protrusion 2022 are hemisphere protrusions.
