DESCRIPTION OF THE PREFERRED EMBODIMENTReference is made toFIG. 1, which is an exploded perspective view of a clipping piece structure for goggles, with a strap and protective goggles according to the present invention. The present invention provides aclipping piece structure1 that is adapted to every kind ofprotective goggles9. Theprotective goggles9 include anelastic strap8, alens92 and aframe94. Thelens92 is used to protect the user's eyes. Theframe94 has an outer side and an inner side, wherein the outer side is engaged with thelens92, and the inner side contacts the user's face. Thelens92 and theframe94 have a pair of protrudingportions922,942 that protrude from their two sides, respectively. Theprotruding portions922,942 are formed withengaging holes920,940, respectively.
Theclipping piece structure1 is used to connect theelastic strap8, thelens92, and theframe94. Theclipping piece structure1 includes amain body10 and a blockingpiece20. Themain body10 includes astrap connecting part12 and a pair of hookingarms16 positioned at one side of thestrap connecting part12. Thestrap connecting part12 is used to connect with theelastic strap8. In this embodiment, thestrap connecting part12 has afriction rod122 and a pair ofslits124,126 that are respectively formed at two sides of thefriction rod122. Theelastic strap8 passes through theslit124, which is positioned at the inner side of thefriction rod122, from the inside to the outside firstly, and is then wrapped around thefriction rod122. Finally, it passes through theslit126, which is positioned at the outer side of thefriction rod122, from the outside to the inside.
This embodiment further includes an extendingportion14 that is located between thestrap connecting part12 and the pair of hookingarms16. The extendingportion14 is connected to one side of thestrap connecting part12. The extendingportion14 in this embodiment has abendable folding portion142 that is connected to thestrap connecting part12. Thefolding portion142 is folded so that thestrap connecting part12 is connected to the extendingportion14 in a bendable way.
The pair of hookingarms16 extends outwardly from one side of the extendingportion14, which defines a receivingspace160 between the pair of hookingarms16. The pair of hookingarms16 respectively form afree end162 that is hook-shaped. InFIG. 1A the free ends162 are the front end and are respectively wedged in the pair of engagingholes920,940 for fixing thelens92 to theframe94. The free ends162 pass the engagingholes940 of theframe94, firstly, and then pass the engagingholes920 of thelens92. The hookingarm16 hooks outwardly with the protrudingportion922 of thelens92.
When a user puts thestrap8 on, thelens92 is pulled to theframe94 by the pair of hookingarms16 because of thestrap8 is pulled back. Therefore, it prevents thelens92 from escaping forward. Moreover, theclipping piece structure1 of the present invention provides a safety function. If the user neglects to assemble thelens92 into theframe94, the pair of hookingarms16 will not be able to engage with thelens92, and theprotective goggles9 can not be worn. Therefore, the present invention prevents the user from wearing thegoggles9 incorrectly.
In this embodiment, each of the hookingarms16 respectively have ananti-sliding portion161 that is formed at its outer side. Theanti-sliding portion161 can be easily engaged by a user via pushing theanti-sliding portion161 with his or her finger. Theanti-sliding portion161 prevents the hookingarms16 from sliding out of place. The receivingspace160 has a curved space (not labeled) that extends from the extendingportion14 to the pair of hookingarms16, and a trapezoid space (not labeled) that communicates with the curved space. Such a shape strengthens the structural intensity of the pair of hookingarms16 while still providing good elasticity.
The blockingpiece20 is disposed movably in the receivingspace160 between the pair of hookingarms16. The blockingpiece20 is propped against the inner side of the pair of hookingarms16. The blockingpiece20 of this embodiment has a shape corresponding to the receivingspace160, and has acurved portion22 and atrapezoid portion24 connected to thecurved portion22. The blockingpiece20 props against the extendingportion14 and the protrudingportion942 of theframe94. The pair of hookingarms16 are therefore restrained, wherein the free ends162 will slant neither up nor down in the engaginghole940 of theframe94 and will not escape from theprotective goggles9.
If the user wants to detach thelens92 form theprotective goggles9 the blockingpiece20 must firstly be taken out from the receivingspace160. Next, the pair of hookingarms16 need to be pushed. The hook-shaped free ends162 can then be separated from theprotective goggles9.

This embodiment provides aclipping piece structure1aincluding amain body10 and a blockingpiece20a. The blockingpiece20ahas acurved portion22 and atrapezoid portion24. Moreover, it further has a pair of protrudingblocks26 protruding from thetrapezoid portion24 along the direction substantially parallel to the pair of hookingarms16.
Reference is made toFIG. 2A. The pair of protrudingblocks26 are wedged in the pair of engagingholes940 of theframe94, respectively. In other words, the pair of protrudingblocks26 and the free ends162 of the pair of hookingarms16 are all wedged into the pair of engagingholes940 of theframe94 together. The tolerance that allows the pair of hookingarms16 of themain body10 to move is limited, and they cannot easily escape from theprotective goggles9 because of the angle. When the user pushes thecurved portion22 outward, the blockingpiece20ais separated from themain body10.
