Benefits of technology

In this preferred embodiment, the side shield is initially placed in its operative position before the screw is inserted into a fastener that is placed into the transverse open end of the channel in the side shield to prevent the temple from freely moving within the channel of the side shield in the operative position.

Problems solved by technology

However, the case often arises where the employers do not want the employees removing the safety shields.
Cutting a hole through the temple weakens the temples and often the temples break during drilling.
This is disadvantageous, as repeated placement and removal of the shields weakens the shield's flanges, and eventually the flanges will snap and the entire side shield must be replaced.
Thus, not only is removal difficult, but once the shields are removed, they are not designed to be used again.
Thus, simple installation is not possible.

first embodiment

Most people wearing eyeglass frames do not carry screwdrivers which are necessary to insert and remove the screw 22 from the opening 28 affixed to the temple 14. As an alternative to the first embodiment, it is often desirable to provide an easier means for inserting or removing a screw 22 from the opening 28 to fasten or take off the side shields 12.

In an alternative embodiment a thumbscrew 40 is used in lieu of a screw 22 to enable the user to more easily fasten or take off the side shields 12 from the eyeglass frames 16 with a thumb and index finger.

A second preferred embodiment of the present invention is shown in FIGS. 6, 7, a and 9 (the complete side shield 12 and its associated channel 26 are not illustrated). In this embodiment it is possible to fasten the side shields 12 to either a standard temple (or a specially adapted temple) of an eyeglass frame 44. The kit of this embodiment includes a pair of side shields 12, a pair of thumbscrews 40 for coupling the side shields 12 ...

second embodiment

In a modification to the second embodiment, it may be aesthetically desirable to utilize a screw 46 as a means for fastening the washer 42 to the side shields 12. In this modification shown in FIG. 9, a screw 46 enables one to fasten or take off the side shields 12 from the eyeglass frames 16 with a screwdriver or other tool.

Abstract

A method for mounting safety shields onto eyeglass temples and a kit for carrying out that method. A temple of an eyeglass frame is placed in a channel forming part of a side shield thereafter, a screw is inserted into an opening formed in the side shield and into a member affixed to the temple to create a fastened fit between the temple and the channel which attaches the side shield to the temple. The side shield is placed in its operative position before the screw is inserted into the opening and the fastened fit results from the insertion of the screw into the opening and member which holds the side shield in its operative position. The kit includes a side shield having a longitudinally extending channel into which a longitudinally extending eyeglass temple may be inserted. The channel has an open lateral end through which the temple may be inserted and a supporting lateral end against which the temple may be supported. The side shield further includes an opening extending transversely to both the longitudinal direction and the supporting lateral wall. A screw is adapted to be inserted into the opening and the member so as to force the temple against the supporting end of the channel to create a fastened fit between the side shield and the temple when the temple is located in the channel. Alternatively, a fastener is placed into the transverse open lateral end in the channel of the side shield, to receive a screw which is a adapted to be inserted into the fastener to create a fastened fit and prevent the temple from moving longitudinally within the channel of the side shield.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a method for mounting safety shields onto eyeglass temples and a kit for carrying out that method.2. Description of the Related ArtConventional safety spectacles include side safety shields which are removably affixed. However, the case often arises where the employers do not want the employees removing the safety shields.In the situations where the employer prefers that the shields be permanently affixed, the primary methods of attachment have been rivets, screws, lock-nuts or adhesives. In the prior art systems, the use of screws have required that holes be drilled in the temples of the glasses which has various drawbacks. Cutting a hole through the temple weakens the temples and often the temples break during drilling.U.S. Pat. No. 3,505,679 discloses a pair of safety spectacles having removable side shields. Flanges of the side shield are snapped over the temple of the glasses. This is disadvant...
