The user may subsequently inset the temple (2) into the retainer unit (3). When, the connecting portion (5) is inserted into the cavity (61) at the angle of 50 degrees, the first section of the connecting portion (35) may be initially accommodated in the first chamber (65) of the cavity (61). Further, the first protrusion (32) of the connecting portion (5) is accommodated in the second chamber (66) of the cavity (61) and the second protrusion (34) of the connecting portion (5) is accommodated in the third chamber (67) of the cavity (61). The transitional region (33) between the first protrusion (32) and the second protrusion (34) is accommodated or supported by the serration (68) of the cavity (61). The first protrusion (32) engages with the pair of undercuts (62) in the second chamber (66) when the connecting portion (5) is inserted into the cavity (61). Further, the user may rotate the temple (2) in the clockwise direction with respect to the vertical axis of the retainer unit (3). The first protrusion (32) may engage with the pair of undercuts (62) in the second chamber (66) as the temple (2) is rotated in the clockwise direction. The pair of undercuts (62) and the first protrusion (32) may interlock together for securing the temple with the retainer unit (3). As the temple (2) is rotated in the cavity (61) of the retainer unit (3), the second protrusion (34) in the third chamber (67) engages with the lip portion (63). The lip portion (63) may herein act as a locking member for fixedly securing the connecting portion (5) and the temple (2) with the retainer unit (3). The second protrusion (34) in the third chamber (67) may engage with the lip portion (63) in the form of a snap fit.

If the user intends to change the temple (2) with a desired pattern or color, the user may merely twist the temple (2) in the anti-clockwise direction for dismantling the temple (2) from the retainer unit (2). When the temple (2) is rotated in the anti-clockwise direction, the first protrusion (32) disengages from the pair of undercuts (62) in the second chamber (66) and the second protrusion (34) is unlocked from the lip portion (63) in the third chamber (67). Consequently, the connecting portion (5) is detached from the cavity (61) of the retainer unit (3) and the temple (2) may be removed from the retainer unit (3).

In an embodiment, the above-mentioned configuration of the temple (2) and the retainer unit (3) enables the user to effortlessly disassemble the temple (2) to a different temple (2) of desired color and/or pattern. In an embodiment, the user may remove and attach the new temple (2) without any tools or any assistance.

In an embodiment, the configuration of the pair of undercuts (62) only allows the temple to be inserted into the cavity (61) at the above-mentioned pre-determined angle. Consequently, accidental disassembly or detachment of the temple (2) from the retainer unit (2) is prevented and the temple (2) may be removed only when it is rotated in the anti-clockwise direction to the pre-determined angle.

In an embodiment, the lip portion (63) also prevents the accidental disassembly or detachment of the temple (2) from the retainer unit (2) since, the second protrusion (34) of the connecting portion (5) is locked by the lip portion (63) of the retainer unit (3).

Equivalents

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding the description may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated in the description.
