DETAILED DESCRIPTION OF THE INVENTION
With reference to FIGS. 1-4, a pair of safety glasses according to the present invention includes a body 1 and two shields 2. The body 1 includes a frame 11 and two temples 12. Frame 11 receives two lenses with optical power for use by a user. The frame 11 includes two sides spaced in a width direction, with each side including a rear end 111 having a width in the width direction. A pivotal portion 112 is formed on the rear end 111 of each side, with a width of each pivotal portion 112 in the width direction smaller than the width of the rear end 111. A stop wall 113 is formed at an interconnection between the rear end 111 of each side and one of the pivotal portions 112. Each pivotal portion 112 of the frame 11 includes a pivot hole 114 extending in a vertical direction perpendicular to the width direction.
Each temple 12 includes a front end having a pivotal section 121 pivotably connected to one of the pivotal portions 112. The pivotal section 121 of each temple 12 includes a receiving groove 122 for receiving one of pivotal portions 112 of frame 1. The receiving groove 122 of the pivotal section 121 of each temple 12 includes upper and lower walls 123 and 124. Upper and lower retaining grooves 125 and 126 are formed in the upper and lower walls 123 and 124, with each of the upper and lower retaining grooves 125 and 126 having a rear end wall 127. The pivotal section 121 of each temple 2 includes a pivot hole 128 in the upper and lower walls 123 and 124. A pivot 129 extends through the pivot hole 114 of each pivotal portion 112 of the frame 11 and the pivot hole 128 of the pivotal section 121 of one of the two temples 2. Thus, the temples 12 can pivot relative to the frame 11 between a folded position and an extended position. The pivotal section 121 of each temple 12 in the folded position has a spacing 13 to one of the stop walls 113 of the frame 11 (FIGS. 2 and 4).
Each shield 2 includes a coupling portion 21 on an upper end thereof and a lower shielding portion 22 on a lower end thereof. The coupling portion 21 of each shield 2 includes a coupling groove 211 having upper and lower wall sections 212 and 213 spaced from each other in the vertical direction and a lateral wall section 214 between the upper and lower wall sections 212 and 213. Upper and lower buckle members 215 and 216 are formed on the upper and lower wall sections 212 and 213. Two hooks 217 are respectively formed on the upper and lower buckle members 215 and 216 for engagement with the upper and lower retaining grooves 125 and 126. Each of the upper and lower buckle members 215 and 216 includes a front stop 218 at a front end thereof. Each shield 2 further includes an upper shielding portion 23 extending from the coupling portion 21 in a direction transverse to the lower shielding portion 22.
The frame 11 and the temples 12 are assembled with each other, and two lenses with optical power are received in the frame 11 for rectifying the eyesight of the user. In regular use, the shields 2 are not attached to the body 1 to reduce the overall weight.
When it is desired to form a pair of safety glasses, the temples 12 are pivoted to the folded position, the coupling groove 211 of each of the two shields 2 is coupled to the front end of one of the temples 12 via the spacing 13 between the frame 11 and the temple 12, with the hooks 217 of each shield 2 engaged in the upper and lower retaining grooves 125 and 126 of the temple 12, providing enhanced assembling stability. The hooks 217 abut the end walls 127 to retain the temples 12 in position.
With reference to FIGS. 5-7, when the temples 12 are pivoted to the extended position, the lower shielding portion 22 of each shield 2 covers an area below one of the sides of the frame 1. The upper shielding portion 23 of each shield 2 covers an area above the frame 11. The front stop 218 of each shield 2 is aligned with the stop wall 113 of one of the sides of the frame 11, preventing the shield 2 from disengaging from the body 1. After assembly, receiving hole 211 of each shield 2 receives the rear end 111 of one of the sides of the frame 1 and the pivotal section 121 of one of the temples 12, providing enhanced assembling reliability. Furthermore, the shields 2 shield the pivotal connection areas between the frame 11 and the temples 12 to avoid the eyes of the user from being injured by alien objects while providing enhanced visual quality.
When it is desired to detach the shields 2, the temples 12 are pivoted to the folded position, and the shields 2 can be easily attached by moving away from the body 1.
Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the essence of the invention. The scope of the invention is limited by the accompanying claims.
