ABSTRACT:
The pair of spectacles includes an eye-protecting piece with a transparent plate and two side plates, and a U-shaped frame member. Each of the side plates has an upper section with a top edge, an elongated notch extending downwardly from the top edge, and a plurality of parallel ridges projecting from an inner surface and defining a plurality of parallel grooves which extend between the notch and a free end portion thereof. The frame member has an elongated intermediate portion with two side portions. Each of the side portions has an inner surface formed with a hollow rectangular sleeve constituted by a first wall portion which extends perpendicularly from the side portion, a second wall portion spaced farther away from the intermediate portion than the first wall portion and extending perpendicularly from the side portion, and a third wall portion interconnecting the first and second wall portions. The third wall portion has a resilient projection extending toward the side portion. After assembly, a portion of the side plate between the notch and the free end portion thereof extends into the sleeve such that the first wall portion is received slidably in the notch, the second wall portion engages the free end portion of the side plate while the resilient projection engages one of the grooves.
