Description

SWIMMiNG GOGGLES

BACKGROUND OF THE INVENTION

1. FIELD OF THE INVENTION

[00011 The present invention relates to swimming goggles, and particularly to swimming goggles having a mask-like protective pad and a soft first frame enveloping a hard second frame and which have an enhanced structure formed on a center of an upper portion thereof that are able to prevent the seepage of water when the swimming goggles are in use.

2. RELATED ART [0002] Some swimming goggles with mask-like protective pads are shown in TW utility patent application Nos. 89213591, 89205145, 89215423, 89214699 and US patent No. 6,276,794. Such swimming goggles have protective pads fitting with swimmer's foreheads and below eyeholes, such that the swimmer's eyes are covered by the protective pads, thus the swimmer will not have a feeling of pressure on their eyes and prevent water seepage in use.

[0003] However, no matter the protective pad is assembled or integrated with lens frames, the protective pad disclosed in prior art are kept within a fixed range of span width. The width of swimmer's face may be various sizes.

For instance, when a swimmer with narrow face wears swimming goggles, the protective pad is bent inappropriately and therefore to fit not closely to the swimmer's forehead or the vicinity of eyeholes. In other words, the swimming goggles cannot match different sizes of swimmers' faces and are unable to prevent water seepage in use.

SUMMARY OF THE INVENTION

[0004] Accordingly, an object of the present invention is to provide swimming goggles which have a soft first frame enveloping a hard second frame and which has an enhanced protruding structure formed on a center of an upper portion thereof, which swimming goggles matchswimmers with narrow faces and effectively prevent water seepage in use.

[0005] The enhanced structure of the second frame comprises an enhanced rib on a center of the second frame, and an enhanced wall extending from the enhanced rib toward opposing sides.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] With reference to Fig. 1, swimming goggles 1 in accordance with a first embodiment of the present invention comprise a lens frame 2, lenses 3 and a strap adjusting means 4. The lens frame 2 has a first frame 20 made of soft material, and a second frame 21 made of hard material and enveloped by the first frame 20. The first frame 20 has a first surface 201, a second surface 202 opposite to the first surface 201, and a third surface 203 connecting the first surface 201 and the second surface 202. Compassing grooves 204 are defmed between the first surface 201 and the second surface 202. Recesses 2011 are defined in the first surface 201 for providing distorted resiliency when compressed. A mask-like protective pad 205 is disposed on the second surface 202 for providing a well-fitting and comfortable contact with swimmer's foreheads and also the vicinity below the eyeholes. The second frame 21 defines receiving grooves 210 corresponding to the compassing grooves 204. Ajoint portion 22 is formed between the receiving grooves 210 for connecting the receiving grooves 210. Fastening posts 23 are formed on inner edges of the receiving grooves 210 for preliminarily positioning the lenses 3. The second frame 21 has enhanced structure on a center of an upper portion thereof. Further referring to Fig. 4, the enhanced structure comprises an enhanced rib 211 on a center of the second frame 21, and an enhanced wall 212 extending from the enhanced rib 211 toward left and right opposing sides of the frame. The wall projects outwards from the frame to the greatest extent at the centre of the frame, the extent of outward projection decreasing with the distance from the centre along the upper sides of the frame towards the outer edges. Accordingly, the major central part of the enhanced wall 212 is of the most strength, whereas the extended parts at the ends of the upper sides of the frame are of less strength. Thus, when the swimming goggles 1 are worn and pulled, the middle and upper portion of the second frame 21 will not be bent and distorted, while both sides of the second frame 21 are gradually distorted in contrast. An assembling post 213 is formed on the enhanced wall 212 and in the vicinity of the second surface 202. The enhanced rib 211 and the assembling post 213 facilitate joining of the first surface 201 and the second surface 202 of the first frame 20 by providing a reliable clasping force. Enhanced members 24 are formed below the second frame 21 for improving strength of the second frame 21. The enhanced members 24 are formed below substantially centers of the receiving grooves 210 of the second frame 21, respectively. Each enhanced member 24 has a width decreasing from middle toward both sides thereof.

[0013] The lenses 3 are respectively retained in the receiving grooves 210, and defme a plurality of positioning holes 30 along outer rims thereof. Some positioning holes 30 which correspond to the positioning posts 23 facilitate to position the lenses 3, while other positioning holes 30 provide retention force for integral molding process. The lenses 3 comprise two pieces of lens, each of which is received in an individual receiving groove 210.

[0014] The strap adjusting means 4 comprises buckles 40 and a head strap (not shown) wrapped through the buckles 40. The buckles 40 are respectively assembled on both sides of the second frame 21. Each buckle 40 includes a base 401, arms 402, a support shaft 404 and a securing shaft 405. The base 401 is integrally formed with the second frame 21 and is made of hard material for firmly retaining the buckles 40 to the second frame 21. The arms 402 respectively extend rearwardly from a lower edge and an upper edge of the base 401. Shaft holes 403 are respectively defmed in the arms 402. The support shaft 404 is mounted on the shaft holes 403 being relatively far away from the base 401. The support shaft 404 forms necks 4041 at two ends thereof, thereby the support shaft 404 can be firmly engaged with the shaft holes 403. The securing shaft 405 is mounted on the shaft holes 403 being relatively close to the base 401. A pressing plate 406 pivots to the securing shaft 405 and corresponds to the first surface 201 of the first frame 20. The pressing plate 406 has a first end 4061 biasing against the recess 2011 of the first surface 201. When the pressing plate 406 is pressed toward the first surface 201, the recess 2011 therefore is distorted and produces resilience force in return to drive the pressing plate 406 back. The pressing plate 406 has a second end 4062 for manipulating. At least a first stop member 407 has cross-section in the shape of a right-angled triangleand is formed on a bottom of the second end 4062 for abutting second stop members (not shown) of the head strap.

[0015] During assembly, some positioning holes 30 of the lenses 3 are assembled on the positioning posts 23 to preliminarily position the lenses 3.

Upon integral molding technology, the second surface 202 encompasses the positioning posts 23 and the remained positioning holes 30, whereby the lenses 3 are integrated with the first frame 20. The first surface 201 and the second surface 202 of the first frame 20 encompass the second frame 21, the enhanced rib 211, the joint portion 22, the bases 401 of the buckles 40 and parts of the arms 402. The enhanced walls 212, the enhanced members 24 and the shaft holes 403 of the arms 402 are exposed beyond exterior, as shown in Figs. 2 and 3.

[0016] With reference to Fig.4, the enhanced structure of the second frame 21 ensures strength thereof decreasing from a middle thereof toward opposite sides. Consequently, when the swimming goggles 1 are in use, the center of the upper portion of the second frame 21 will not be bent or distorted, while both sides thereof are gradually distorted to fit to swimmer's foreheads, effectively guarding from water seepage.

[0017] Figs. 5 and 6 show the second embodiment of the present invention.

The swimming goggles 1' of the second embodiment still comprises a first frame 20' made of soft material, and a second frame 21 made of hard material and enveloped by the first frame 20', and a lenses 3' is received in an individual receiving groove 210'. Also an enhanced wall 212' extends decreasingly along upper sides of the second frame 21'; accordingly, the major part of the enhanced wall 212' is of the most strength. The swimming goggles 1' of the second embodiment is rather similar to the swimming goggles I of the first embodiment except that the buckles 6' which are assembled on an assembled hole 2012' of both sides of the soft first frame 20' respectively, the buckle 6' includes a base 60', a cover 61', a shaft 64' and a fastener 67'. The base 60' includes an upper wall 601' substantially perpendicularly extending from an upper portion thereof, and a lower wall 602" substantially perpendicularly extending from a lower portion thereof.

A pair of first axial holes 603' and second axial holes 604' are defmed in the upper and lower walls 601', 602', respectively. A pair of recesses 605' is defined in the upper and lower walls 601', 602', and a pair of fixing protrusions 611' is formed at the cover 61' corresponding to the recesses 605' for snappingly engaging with the recesses 605' thereby fixing the cover 61' to the base 60'. A post 606' extends from the base 60' for engagingly extending into the assembled hole 2012', thereby fixing the buckle 6' to the both sides of the soft first frame 20'. The shaft 64' is rotatably assembled between the upper and lower wall 601', 602' with end portions thereof received in the first axial hole 603' for providing a head strap 41' passing throught. The head strap 41' forms second stop members 410' with right-triangle ladderlike cross-section and spaced the same distance apart from each other.

[0018] The fastener 67', including an body 671', a handle 672' extending from the body 671', and a first stop member 673' extending from the body 671' opposite the handle 672', is assembled between the upper and lower walls 601', 602' with end portions of the body 671' mounted on the second axial holes 604'. The handle 672' is generally arc-shaped and the first stop member 673' is generally barb-shaped for selectively engaging with the second stop member 410' of the head strap 41' for engaging the first stop member 673' in a single direction of tightening instead of a direction of loosening, thereby fixing the head strap 5 to the buckle 6'. The body 671' is parallel and adjacent to the shaft 64'. A tongue 674' integrally extends from a side of the handle 672' adjacent to the body 671' and can be leaned against a concavity 2011' of the soft first frame 20'after assembly and the tongue 674' will return position automatically by resilience provided by quality of material of the concavity 2011'. It is understood that the buckle in different way can be assembled on the soft first frame 20' to get with the same functions and the enhanced wall 212' of the second embodiment will not be bent or distorted, while both sides thereof are gradually distorted to fit to swimmer's foreheads, effectively guarding from water seepage in use.

[0019] It is understood that the invention may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
