1. Fields of the Invention
The present invention relates to a connection device, and more particularly, to a connection device for easily connecting lenses to a frame, and removing lenses from the frame.
2. Descriptions of Related Art
The conventional glasses generally comprise a frame and two lenses engaged with two lens rims, and two temples are pivotably connected to the frame so as to be worn to the user's ears. The lenses are forced to be fitted with the grooves defined in the insides of the lens rims, and this is not easy and takes a lot of time. The lenses can be broken if the installation is not properly. Therefore, some manufacturers develop lenses and/or parts replaceable glasses, such that the glasses may have different appearances and more attractive.
The present invention intends to provide a pair of glasses with a simple connection device which allows the users to easily replace lenses.
The present invention relates to a connection device and comprises a frame having at least one reception slot defined therein. The at least one reception slot has an engaging slot. Two pivot recesses are defined in two insides of the at least one reception slot. A lens unit has a notch defined in the top edge thereof and the notch is located corresponding to the engaging slot. A connection member is engaged with the reception slot and has two pivots extending from two sides thereof. The two pivots are pivotably engaged with the two pivot recesses of the frame. The connection member has a protrusion which is located corresponding to the engaging slot of the lens unit. The protrusion is engaged with the frame and the notch of the lens unit to combine the lens unit with the frame.
Preferably, the notch of the lens unit, the engaging slot of the reception slot and the protrusion of the connection member are dove-tailed.
Preferably, the connection member has an inclined face which faces the frame so that a user pushes the inclined face to remove the protrusion from the notch of the lens unit and the frame.
The primary object of the present invention is to provide a simple connection device to easily connect a lens unit to a frame, or to easily remove a lens unit from a frame.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
A lens unit 2 has a notch 21 defined in the top edge thereof and the notch 21 is located corresponding to the engaging slot 111.
A connection member 3 is engaged with the reception slot 11 and has two pivots 31 extending from two sides thereof. The two pivots 31 are pivotably engaged with the two pivot recesses 112 of the frame 1. The connection member 3 has a protrusion 32 which is located corresponding to the engaging slot 111 of the lens unit 2.
As shown in
The present invention can easily replace or change a different lens unit 2 by simply operating the connection member 3. It is noted that the connection member 3 is connected with the frame 1, so that the connection member 3 does not lost during replacement of the lens unit 2.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
