Coupling unit for eyeglass frames, and an eyeglass frame comprising the unit
View Patent ↗A coupling unit for eyeglass frames for coupling the eyeglass frame front ( 1 ) to the temple ( 3 ), where the coupling unit comprises a subunit of the eyeglass frame front ( 1 ) and a subunit of the temple ( 3 ), and where the subunit of the eyeglass frame front ( 1 ) comprises two pins ( 2 ), and the subunit of the temple ( 3 ) comprises two sockets ( 4 ) in which the said pins ( 2 ) are fitted pivotally, and where placed between the said sockets ( 4 ) is a resilient element ( 5 ) of the subunit of the temple ( 3 ) which protrudes beyond the said sockets ( 4 ), and placed between the said pins ( 2 ) of the subunit of the eyeglass frame front ( 1 ) is a guiding element ( 6 ) for the said resilient element ( 5 ) is characterized in that the subunit of the eyeglass frame front ( 1 ) features an opening ( 7 ) to accommodate the resilient element ( 5 ) of the subunit of the temple ( 3 ) whenever the temple ( 3 ) is pivoted away by any angle larger than 90° with respect to the subunit of the eyeglass frame front ( 1 ).
1 . A coupling unit for eyeglass frames for coupling the eyeglass frame front to the temple, where the coupling unit comprises a subunit of the eyeglass frame front ( 1 ) and a subunit of the temple ( 3 ), and where the subunit of the eyeglass frame front ( 1 ) comprises two pins ( 2 ), and the subunit of the temple ( 3 ) comprises two sockets ( 4 ) in which the said pins ( 2 ) are fitted pivotally, and where placed between the said sockets ( 4 ) is a resilient element ( 5 ) of the subunit of the temple ( 3 ) which protrudes beyond the said sockets ( 4 ), and placed between the said pins ( 2 ) of the subunit of the eyeglass frame from front ( 1 ) is a guiding element ( 6 ) for the said resilient element ( 5 ) of the subunit of the temple ( 3 ), wherein the subunit of the eyeglass frame front ( 1 ) features an opening ( 7 ) to accommodate the resilient element ( 5 ) of the subunit of the temple ( 3 ) whenever the temple ( 3 ) is pivoted away from the folded position with respect to the subunit of the eyeglass frame front ( 1 ), wherein, the resilient element ( 5 ) of the subunit of the temple ( 3 ) passes through the opening ( 7 ) from the outside of the subunit of the eyeglass frame front ( 1 ) only whenever the temple ( 3 ) is pivoted away by any angle larger than 90° from the folded position of the temple ( 3 ) with respect to the subunit of the eyeglass frame front ( 1 ).
2 . The unit according to claim 1 , characterized in that the subunit of the eyeglass frame front ( 1 ) constitutes an integral part of the eyeglass frame front ( 1 ).
3 . The unit according to claim 1 , characterized in that fixed to the guiding element ( 6 ) of the subunit of the eyeglass frame front ( 1 ) is an additional guiding element ( 6 a ) in the form of a cap with rounded working ends ( 6 a ′).
4 . The unit according to claim 3 , characterized in that the resilient element ( 5 ) of the subunit of the temple ( 3 ) features a profiled socket ( 5 a ) to accommodate the ends ( 6 a ′) of the additional guiding element ( 6 a ) of the subunit of the eyeglass frame front ( 1 ).
5 . The unit according to claim 1 , characterized in that the subunit of the temple ( 3 ) constitutes an integral part of the said temple ( 3 ).
6 . The unit according to claim 1 , characterized in that the resilient element ( 5 ) of the subunit of the temple ( 3 ) features a profiled socket ( 5 a ) to accommodate the ends of the guiding element ( 6 ) of the subunit of the eyeglass frame front ( 1 ).
7 . An eyeglass frame comprising an eyeglass frame front ( 1 ), two temples ( 3 ), and two coupling units according to claim 1 to connect the front ( 1 ) of the eyeglass frame to the temples ( 3 ).
8 . The eyeglass frame according to claim 7 , characterized in that the eyeglass frame front ( 1 ) and the temples ( 3 ) are made of metal.
9 . The eyeglass frame according to claim 7 , characterized in that free ends of the temples ( 3 ) feature flexible elements ( 8 ).
