The present invention relates to an assembly for protective goggles; particularly, the present invention relates to an assembly of protective goggles combining integrally formed lens with a frame with a strap such that the goggles for sport use can be easily implemented through easily assembling operation.
A variety of the conventional eyeglasses include those for vision correction and those for sport purpose as well as those for protecting eyes from being hurt by strong external light. Users may select an appropriate kind among these eyeglass assemblies with different purposes in accordance with their needs. The present invention improves the eyeglass assembly for sport purpose, utilizing the current eyeglass assembly of the kind, which usually combines integrally formed lens with a protective frame and having a strap at two ends of the protective frame that can be comfortably fitted with a head of a user.
The present invention improves the conventional sport goggle assembly into a different assembly through combining a frame and an integrally formed lens with a strap at two ends such that the assembly and manufacture of components can be more easily implemented.
One aspect of the present invention is to provide a pair of protective goggles having an integrally formed lens, a frame with a protective pad formed of a soft material and a strap with buckles combined with both ends. The lens has an opening formed at a middle section of an upper side for correspondingly engaging with an engaging portion on an upper side of the frame, a protrusion extending upwardly from an inner surface of a nose supporting portion at a lower side to be correspondingly inserted into a hole adjacent to a concave section formed on a middle section of a lower side of the frame for positional restriction, a designed through hole formed on each end and a aperture adjacent to each through hole. The frame further has more than one rib provided on the upper side for correspondingly fitting with the lens and for stably propping the lens, and a designed through hole provided on each end with raised portions projected around for passing through the corresponding designed through hole of the lens and a tenon formed adjacently for passing through the corresponding aperture of the lens. Each buckle combined with each end of the strap has an engaging section subsequently passing through the through holes of the lens and the frame, and a boundary portion formed at an open end of the engaging section rotated at a direction so as to stably lean against an inner surface of the through holes of the frame. As a result, easy assembling and stable combination for the protective goggles are achieved.
Referring to
The lens 1 is formed of hard material having an integral covering edge 11 extending backward from a periphery thereof, an opening 12 formed at a middle section of an upper side, a protrusion 13 extending upwardly from an inner surface of a nose supporting portion at a lower side, designed through hole 14 provided on two ends respectively, and apertures 15 adjacent to respective through holes 14.
The frame 2 has a protective pad 28 integrally formed of a softer plastic material on the back and is shaped to the periphery of the lens 1. The frame 2 has an engaging portion 21 provided on a middle section of an upper side, a hole 23 provided adjacent to a concave section 22 formed on a middle section of an lower side, more than one rib 24 provided on the upper side, and designed through holes 25 respectively provided on left and right ends. Each through hole 25 has raised portions 26 projected from a periphery thereof and a tenon 27 formed adjacently.
The strap 4 has two ends respectively combined with buckles 3 each having an engaging section 31 extending from one side thereof. The engaging section 31 is formed with a boundary portion 32 at an open end.
The protective goggles for sport purpose in accordance with the present invention have the following advantages:
1. The integrally formed lens and the frame are combined through engaging the upper and lower sides of the lens and the frame so as to obtain a stable combination between the two elements and so that disassembly of the two element can be implemented easily; and
2. The assembly of the lens and the frame is further assembled with the buckles at the two ends of the strap through passing each engaging section of the buckle subsequently through the through holes of the lens and the frame and rotating the buckle is rotated at an direction till, the boundary portion of the engaging section is stably against an inner surface of the frame, thereby achieving easily stable combination and fast disassembly for the protective goggles.
