## Title
Swimming goggles

## Abstract

Swimming goggles have a left frame, a right frame and a connecting frame connecting the left frame and the right frame. The left frame and the right frame are made of hard material. Enveloping frames are respectively formed adjacent to the inner surfaces and slightly offset relative to outer rims of the peripheral surfaces. Fastener base are respectively formed on outward sides of the enveloping frames for movably receiving head strap. The connecting frame is made of soft material, and includes a nose bridge, a left pad and a right pad respectively on left and right sides of the nose bridge. Thus head strap easily move through the fastener base made of hard material, while the left pad and the right pad touch a user softly. The nose bridge supports the support portions of the left frame and the right frame reliably, so the swimming goggles are used comfortably and avoiding distortion of the left frame and the right frame.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to swimming goggles, and particularly to swimming goggles which have soft nose bridge and pads unitarily formed and integrally connecting with hard frames, wherein the nose bridge is inch-adjustable for comfortable use and is not subject to movement of head strap.
2. Related Art
As for swimming goggles, especially for swimming goggles with frames, a nose bridge and pads integrated together, comfortable touch upon a user is always taken into consideration. The frames, the nose bridge and the pads of such swimming goggles are usually made of soft material. However, the frames tend to distort when moving head strap. To overcome this problem, some swimming goggles have strengthened frames which are made of hard material and a nose bridge which is made of soft material. For example, one of conventional swimming goggles has a soft nose bridge with arc-shaped cross-section, wherein the arc has thick medium portion and thin end portion. Stop portions are provided on outsides of the frames for abutting a plate of the head strap. When pulling the head strap, pulling strength are mainly distributed on thick medium portion of the nose bridge, thereby avoiding distortion of the frames.
The nose bridge made of soft material is fixed on inner sides of the frames, and can not supports the hard frames reliably. Additionally, width of the nose bridge can not be adjusted to suit for a user's nose. The users with relatively high nose may feel uncomfortable for compression of the nose bridge.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide integral swimming goggles which have soft pads and nose bridge unitarily enveloped by hard frames, wherein the nose bridge reliably supports the frames and is inching-adjustable.
The swimming goggles comprise a left frame, a right frame and a connecting frame connecting the left frame and the right frame. The left frame and the right frame are made of hard material, and respectively include inner surfaces, outer surfaces and peripheral surfaces between the outer surfaces and the inner surfaces. Enveloping frames are respectively formed adjacent to the inner surfaces and slightly offset relative to outer rims of the peripheral surfaces. Fastener base are respectively formed on outward sides of the enveloping frames. Support portions integrally and outwardly extend from the peripheral surfaces, respectively. The connecting frame is made of soft material, and includes a nose bridge, a left pad and a right pad respectively on left and right sides of the nose bridge.
The fastener base include body defining fastener holes for movably receiving head strap, and connecting portions. The connecting portions respectively connect and space the body of the fastener base with the left frame and the right frame, thereby facilitating the connecting frame to support the left frame and the right frame.
Extending portions integrally and outwardly extend from the enveloping frames. The extending portions are integrated with and below the support portions and intersect to form at least a transition point for enhancing flexibility of the support portions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to FIG. 1, swimming goggles 1 of the present invention comprise a left frame 2, a right frame 3, a connecting frame 4 connecting the left frame 2 and the right frame 3 and head strap (not shown). The left frame 2 and the right frame 3 are made of hard material and respectively have inner surfaces 20, 30, outer surfaces 21, 31 and peripheral surfaces 22, 32 between the outer surfaces 21, 31 and the inner surfaces 20, 30. Receiving passages 201, 301 are respectively defined between the inner surfaces 20, 30 and the outer surfaces 21, 31 for accommodating lens 5. Enveloping frames 28, 38 are respectively formed adjacent to the inner surfaces 20, 30 and slightly offset relative to outer rims of the peripheral surfaces 22, 32. Fastener base 23, 33 are respectively formed on outward sides of the enveloping frames 28, 38 and are spaced a certain of distance from the inner surfaces 20, 30. Further referring to FIG. 5, fastener base 23, 33 include body 231, 331, and connecting portions 233, 333 respectively for connecting the fastener base 23, 33 with the left frame 2 and the right frame 3. The connecting portions 233, 333 space the body 231, 331 a distance from the inner surfaces 20, 30, thereby facilitating the connecting frame 4 to cover the enveloping frames 28, 38 of the left frame 2 and the right frame 3 securely. Fastener holes 232, 332 are respectively defined in the body 231, 331 for receiving head strap. Support portions 24, 34 integrally and outwardly extend from the peripheral surfaces 22, 32, respectively. The support portions 24, 34 are slightly inclined forwardly. Extending portions 29, 39 integrally and outwardly extend from the enveloping frames 28, 38, respectively. The extending portions 29, 39 are integrated with and below the support portions 24, 34 and intersect to form a transition point 80 for enhancing flexibility of the support portions 24, 34.
The connecting frame 4 is made of soft material, and includes a nose bridge 40, a left pad 41 and a right pad 42 respectively on left and right sides of the nose bridge 40, and a linking portion 43 integrally extending from the nose bridge 40 for connecting with the left pad 41 and the right pad 42. Assembling openings 401, 402 are respectively defined at left and right sides of the nose bridge 40 for receiving the support portions 24, 34. The linking portion 43 encircles the enveloping frames 28, 38 in assembly.
With reference to FIGS. 2 and 3, in assembly, the connecting frame 4 unitarily connects the left frame 2 and the right frame 3. The nose bridge 40 surrounds the extending portions 29, 39. Further referring to FIGS. 1 and 6, the support portions 24, 34 and the extending portions 29, 39 are received in the assembling openings 401, 402 of the nose bridge 40. So the swimming goggles 1 are used comfortably and far from distortion of the left frame 2 and the right frame 3. As shown in FIG. 7, the linking portion 43 of the connecting frame 4 encircles the enveloping frames 28, 38, thereby supporting the left frame 2 and the right frame 3. The connecting portions 233, 333 produce offset between the fastener base 23, 33 and the left frame 2 and the right frame 3, whereby the connecting frame 4 encloses outer peripherals of the left frame 2 and the right frame 3 firmly. In other words, the nose bridge 40 and the left and right pads 41, 42 made of soft material enclose the left frame 2 and the right frame 3 made of hard material. Thus head strap can be easily adjusted through fastener holes 232, 332 of the left frame 2 and the right frame 3, while the left pad 41 and the right pad 42 touch a user softly.
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.
