说明书全文 | 1. Field of the Invention The present invention relates to an improvement on eyeglasses, more particularly one, which have spring-biased elements capable of snapping onto front protruding portions of the temples and holding the temples in position when the temples are pivoted to the not-in-use position, and when the temples are pivoted to the in-use position. 2. Brief Description of the Prior Art Spring-biased temples of eyeglasses are available, which make the eyeglasses more comfortable to wear. A conventional eyeglasses temple includes a supporting part, a sleeve, a spring, and a confining block, and it has the following disadvantages: The spring is prone to pinch and hurt the wearer's skin. There is no position maintaining means for holding the temples in position after the eyeglasses are moved to their in-use position and folded one. Consequently, the temples are prone to shake, and will occupy more space when the eyeglasses aren't in use. It is a main object of the invention to provide an improvement on eyeglasses structure to overcome the above-mentioned problems. The eyeglasses of the present invention include two rims, and two temples; each rim has a cavity, a spring held in the cavity, a holding element, which is positioned partially in the cavity so as to be around and cover the spring, and has a pressing portion; each temple has a protruding portion, which has a locating concavity, and a position holding portion. The temples are pivoted to the rims with the holding elements being pressed against the protruding portions of the temples at the pressing portions. The temples will be held in position with the holding elements being pressed against the locating concavities when they are in the in-use position. The temples will be held in position with the holding elements being pressed against the position holding portions when they are in the not-in-use position. The holding elements will snap onto the locating concavities in an easily perceptible manner as soon as the temples are pivoted to the in-use position. The holding elements will snap onto the position holding portions of the temples in an easily perceptible manner as soon as the temples are pivoted to the not-in-use position. The present invention will be better understood by referring to the accompanying drawings, wherein: Referring to Each of the rims 1 has an internal cavity 11, a spring 13 held in the internal cavity 11, a holding element 12 positioned partially in the internal cavity 11 and covering the spring 13, and two opposing pivotal holes 14; the holding element 12 has a holding hole 121 containing the spring 13, and a pressing portion 122 outside the internal cavity 11. Each of the temples 2 has a protruding portion 21 on a front end, which has a connecting hole 211, a locating concavity 212, and a position holding portion 213 thereon. The temples 2 are inserted between the opposing pivotal holes 14 of respective ones of the rims 1 at the protruding portions 21 thereof, and connecting elements 141 are passed through the pivotal holes 14 and the connecting holes 211 of the protruding portions 21 of the temples 2; thus, the holding elements 12 are biased to touch the protruding portions 21 of the temples 2 at the pressing portions 122 thereof by the springs 13, and the temples 2 are pivoted to the rims 1. In assembly, referring to From the above description, it can be seen that the eyeglasses of the present invention have the following advantages: the temples will be held firmly in position no matter which one of both the in-use and the not-in-use positions they are in, and the eyeglasses will snap in an easily perceptible manner as soon as the temples are pivoted to the in-use position, and as soon as the temples are pivoted to the not-in-use position. |
