Description
An attachment device for an eyewear frame arrangement
Field of invention
This invention relates to an eyewear attachment method and device, such as clip-on eyewear, and more particularly relates to a secondary eyewear for attaching secondary sunglass lenses to conventional primary eyewear.
Background of the invention
Secondary eyewear to convert conventional primary eyeglasses to sunglasses is very popular. They allow the user to usually avoid the need for two separate prescription glasses. They can be used, but less frequently, to attach secondary eyewear that can change the prescription of the lenses. The more common use, however, is to add tinted lenses to conventional primary eyewear. This option is useful in sunny climates, where this type of spectacle arrangement can reduce sun glare. Further, it is especially useful for users who may wish to avoid the use of contact lenses when requiring glare reduction, as conventional sunglasses usually do not come with prescription, or the use of two separate prescription glasses. Certain users may have adverse reaction to the wearing of contact lenses, or may face discomfort or fatigue when using such lenses, especially after long periods of time. . .
It is to be understood that use of the terms eyewear and eyeglasses refer to conventional spectacles, lens, or lens frame assemblies.
There are many known methods to attach the secondary lens or lens frame to conventional primary lens or lens frame.
Mechanical clips or hooks
This method involves securing a secondary lens or lens frame assembly onto conventional primary eyewear and involves the use of clips or hooks, usually provided on the secondary lens or lens frame. Engagement of the secondary eyewear to the primary eyewear is usually at 3 contact areas; the bridge portion of the primary eyewear, and at the peripheral rims located near the lateral temple bars on both sides of the primary eyewear. To effect the engagement between the secondary eyewear onto the primary eyewear, a user would
- 1 -
need to manipulate the secondary eyewear so that it can form an engagement at the 3 connecting points.
Although simple to use, this method of attachment does not achieve the aesthetic appeal that users will usually want to be associated when using a pair of eyeglasses. The use of mechanical clips or hooks may degrade the appearance of the overall eyewear arrangement as they draw attention to the edge of the. entire eyewear attachment.
Further, repeated use will deform the secondary eyewear arrangement, as mounting and dismounting the secondary eyewear usually requires the user to manipulate the secondary eyewear. In the long run, it will be difficult to ensure stable fitting and orientation, and may eventually degrade the user's vision due to inevitable misalignment of the lenses after prolonged manipulation. The high number of mechanical clips or hooks required to attach the secondary eyewear to the conventional primary eyewear will cause unsightly scratches to the secondary and primary eyewear during mounting and dismounting. In an extreme scenario, this may even cause breakage of the secondary eyewear.
Magnetic material
This is a newer version of attaching secondary eyewear to a conventional primary eyewear involving the use of magnetic portions.
Commonly, a magnetic material is embedded in an extension socket mounted in the secondary eyewear. Magnets of opposing polarities would then be positioned on the temple regions of the conventional primary eyewear.
This method of attachment is cumbersome, as a user would have to perfectly align the magnetic regions of the primary and secondary eyewear before they can be magnetically attached. Further, magnetic attachment means are not known to form a strong bond, and may not withstand the wearer's strenuous activity. In such a case, the secondary eyewear may detach itself from the primary eyewear after sorhe time or due to some physical activity of the wearer.
A common drawback of these two kinds of attachments is that the primary eyewear is susceptible to scratches. To alleviate this problem to a certain extent, frame manufacturers have resorted to creating a greater allowance between the primary and secondary eyewear and lenses. However, this increase in allowance may cause an effect known as the
ghosting effect, which causes the wearer to see double vision. This again, may eventually degrade the vision of the user.
Groove and protrusion This method of attachment is the subject of Singapore application no. 200105419-6. This system allows a user-produced groove on the secondary eyewear, to be fitted on the protrusion provided on the primary eyewear. Though this system allows the allowance between the primary and secondary lenses to be minimized, thus reducing the ghosting effect, a user needs to accurately align the protrusion to the groove to cause the attachment. This may be cumbersome, and to some extent, a tedious task.
It is an object of the present invention to alleviate the problems highlighted above.
Summary of invention
According to the present invention, there is provided an attachment device adaptable to be positioned between a primary eyewear and a secondary eyewear including a protective pad for preventing the forward facing surface of the primary lens and the rearward facing surface of the secondary lens from being in direct contact, an engagement means for attaching said protective pad to the forward facing surface of the primary or the rearward facing surface of the secondary lens or lens frame, wherein the protective pad creates a frictional resistance between the primary lens and secondary lens or lens frame.
In a preferred embodiment, the secondary eyewear has at least a hook to attach the rear surface of the secondary eyewear to the front surface of the primary eyewear.
In a further preferred embodiment, the attachment device is to be attached to the forward facing surface of the primary lens of the primary eyewear.
In a still further preferred embodiment of the present invention, the attachment device is to be attached to the rearward facing surface of the secondary lens of the secondary eyewear.
In yet another preferred embodiment, the protective pad is patterned or ribbed to enhance the frictional resistance between the primary lens and the secondary lens.
In a further preferred embodiment, the protective pad is made of a resilient material so that it can withstand a wearer's strenuous activity, and will retain its original shape and thickness once it is released from its contact with either the primary eyewear or secondary eyewear. Thus, a minimum allowance between the rearward facing surface of the secondary lens of the secondary eyewear and the forward facing surface of the primary lens of the primary eyewear can still be maintained after sustained usage. In use, the protective pad of the attachment device spreads out upon contact with the primary or secondary lens or lens frame, and increases the surface area, and thus increases frictional resistance between the primary and secondary lens or lens frame.
Preferably, the resilient material of the protective pad is silicone or any silicone substitute or any other material or polymer of the art, which can impart resilience to the protective pad of the present invention.
In a still further preferred embodiment, the engagement means can be manually fitted to the primary or secondary lens of the user and allows the user to adopt the present arrangement of the present invention to a conventional primary and secondary eyewear arrangement without having to purchase another set of eyewear, or wait for a manufacturer fitted eyewear incorporated with the attachment device.
In a further preferred embodiment, the engagement means is a screw to allow the user ease of adopting existing tools for attaching the attachment device to the forward facing portion of the primary or the rearward facing portion of the secondary eyewear. It is to be understood that this invention does not limit the engagement means to be a screw, and further extends the interpretation of the engagement means to pins, tacks, fasteners, or any mechanical equivalent of the screw. These substitutes or combinations of any substitutes can easily replace the engagement means as preferred in the present invention without departing from the spirit of the invention. Further, the engagement means can be of conventional adhesives, which can affix the attachment device to either the forward facing surface of the primary lens or the rearward facing surface of the secondary lens of conventional spectacle frame arrangements.
In a still further preferred embodiment, the protective pad will at least contact the forward facing surface of the primary lens and the rearward facing surface of the secondary lens to allow this contact to provide a frictional resistance, and to create a durable grasp or hold
between the primary and secondary lenses. This further minimizes the occurrence of scratches on the lenses after prolonged use. It should be understood that the attachment device may be engaged on either the forward facing surface of the primary lens or the rearward facing surface of the secondary lens, as long as the attachment device is between the primary and the secondary lens.
In a preferred embodiment, the hook of the secondary eyewear is made of a pliable or malleable material so that a user may adjust the length of extension of the hook to adjust the allowance between the primary lens and the secondary lens.
In a further preferred embodiment, the hook further includes a protective sleeve to enhance the frictional resistance between the hook and the primary eyewear. This protective sleeve has the added advantage in that it serves to prevent scratches that may be caused by the hook during the mounting and dismounting of the secondary eyewear from the primary eyewear.
In a still further preferred embodiment, the sleeve is made of a resilient material to withstand the repeated mounting and dismounting of the hook to the primary eyewear when a user needs to attach a secondary eyewear to a primary eyewear.
In yet another preferred embodiment, the sleeve is of a bulbous shape. It is preferred that the rounded portion of the sleeve extends below the primary bridge, to allow the bulbous shape to better engage the hook to the primary eyewear.
In another preferred embodiment, the hook when in use, allows the sleeve to at least contact the secondary eyewear when forming an engagement between the primary eyewear and the secondary eyewear.
Preferably, the attachment device is positioned such that when in use, the attachment device is hidden from the view on the forward facing side of the secondary lens. For example, in Singapore application number 200105419-6, the attachment device is preferable engaged on the rearward facing portion of the secondary bridge portion of the secondary eyewear, or in other conventional secondary eyewear in the market, on the opposed side of a design detail of the secondary eyewear.
It is known in the art for secondary bridge portions to be attached to secondary lenses or lens frames using a bridge screw plug. In a preferred embodiment, the attachment device is engaged through the bridge screw plug, to effect a stronger engagement with the secondary lens.
According to another aspect of the invention, there is provided an engagement means to engage the attachment device onto either the forward facing portion of the primary lens or the rearward facing portion of the secondary lens of the primary or secondary eyewear, to be used in the present invention.
In a preferred embodiment, the protective pad is incorporated onto the engagement means.
Preferably, the protective pad is attached to the top surface of the engagement means
Still preferably, the protective pad is attached flush with the top surface of the engagement means.
According to another aspect of the invention, there is provided a method of attaching an attachment device according to the invention including the steps of attaching a protective pad onto an engagement means, and affixing the engagement means onto the primary or secondary lens.
