[embodiment]
The resilient glasses legs of the utility model embodiment 1 has hinge part 1, legs and feet section 2 and two contiguous blocks 3, and hinge part 1, contiguous block 3 are connected with legs and feet sections and are connected by an elastic metallic yarn 4.
In the present embodiment, the front and back end of contiguous block 3 is all the inclined-plane, the side be shaped as parallelogram, the front end of the rear end of hinge part 1 and legs and feet section 2 is the inclined-plane.Between two contiguous blocks 3, leave gap delta between contiguous block 3 and hinge part 1, legs and feet section 2.
The elastic metallic yarn 4 of the present embodiment adopts diameter d to equal the circular Ti-Ni alloy silk processing and fabricating of 1.4mm.The xsect that is washed into the elastic metallic yarn 4 after type is cruciform, and elastic metallic yarn 4 cross-like cross-section have two of up and down lug, nib 401 and two of left and right lug, nib 402.The up and down two lug, nibs 401 be that punching press is extruded, the distance H between end face greater than between lug, nib 402 end faces of two of left and right apart from B.
Elastic metallic yarn 4 passes the connecting hole of contiguous block 3, and the connecting hole of hinge part 1 and legs and feet section 2 ends is inserted respectively at two ends.Elastic metallic yarn 4 respectively with hinge part 1, contiguous block 3, legs and feet sections 2 axial restraints.
The connecting hole at hinge part 1 and legs and feet section 2 two ends and and the connecting hole at two contiguous block 3 middle parts be all shape, measure-alike cruciform vent.Therefore only describe as an example of the connecting hole at contiguous block 3 middle parts example.
The cruciform vent of contiguous block 3 has circular hole 301 and two relative keyways 302, the diameter D1 of circular hole 301 equal between lug, nib 402 end faces of (or greater than) elastic metallic yarn two of 4 left and right apart from B, but less than the distance H between lug, nib 401 end faces of two of up and down.
Elastic metallic yarn Shang Xia 4 the distance H between two lug, nib 401 end faces equal distance H 1 between the relative keyway of 3 two of (or less than) contiguous blocks 302 bottom surfaces, the width B 1 of elastic metallic yarn two lug, nibs 401 Shang Xia 4 is less than the width of 3 two relative keyway B2 of (or equaling) contiguous block.After elastic metallic yarn 4 was inserted in the cruciform vent of contiguous block 3, both can not relatively rotate.
Different from the connecting hole at hinge part 1 and legs and feet section 2 two ends is, contiguous block 3 length are larger, connecting hole for the ease of processing contiguous block 3, contiguous block 3 also comprises two fabrication holes 303, fabrication hole 303 is positioned at the two ends of the connecting hole of contiguous block 3, fabrication hole 303 is coaxial with the connecting hole of contiguous block 3, and the diameter D2 of fabrication hole 303 equals the distance H 1 between (or greater than) two relative keyway 302 bottom surfaces.
