A slit is defined between joint surfaces of the first arm and the second arm and is located adjacent a user's temple when being worn. A stem extends from an end of the first arm/the second arm. An engaging portion is formed at an end of the stem. The frame bodies are respectively assembled on the passageways of the clamp frames. A receiving slot is defined in an inner surface of each frame body.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to swimming goggles, and particularly to swimming goggles which are assembled by latching and pressing and which have large side field of vision.

2. Related Art

Swimming goggles have a variety of shapes and structures. In consideration of assembly of lenses, swimming goggles are generally of three types: integrating type, implanting type and pressing type. The integrating type of swimming goggles has lenses integrated with frames. The implanting type of swimming goggles has lenses implanted into and then integrated with frames. The pressing type of swimming goggles has lenses assembled on a mask-like pad and then assembled on and pressed to frames. The instant invention is involved in the pressing type of swimming goggles. A conventional pressing type of swimming goggles have frames with slits for facilitating assembly of lenses, and pressing members for pressing against to join the slits. However, the pressing members of the pressing type are adjacent to a user's cheekbones and hide from the view beside eyes. So the user's eyes can not reach side view except by rotating his/her head. This defect makes the conventional pressing type of swimming goggles not meet product requirement of some countries.

Moreover, because of different profiles of users' heads, users have to pull two strips of a head strap to adjust the swimming goggles to appropriate positions. However, the adjusting positions of the head strap are adjacent to ends of eyes. Once pulling the head strap up and down, the frames are often pulled up and slantwise, making users feel uncomfortable. The frames are also not aligned with the eyes.

SUMMARY OF THE INVENTION

To overcome the shortcomings, an object of the present invention is to provide swimming goggles which touch users closely and are worn comfortably and which have large side field of vision.

The swimming goggles comprise two clamp frames, two frame bodies, two lenses respectively received in the receiving slots of the frame bodies, pressing devices for pressing the first arm and the second arm to close, and a head strap assembled on the engaging portions of the stems. The clamp frames are made of hard material. Each clamp frame defines a passageway, and has an assembling portion on an inward side thereof. A first arm and a second arm respectively extend from an outward side of the clamp frame and opposite to the assembling portion. A slit is defined between joint surfaces of the first arm and the second arm and is located adjacent a user's temple when being worn. A stem extends from an end of the first arm/the second arm and has appropriate length. An engaging portion is formed at an end of the stem. A connecting member connects the assembling portions of the clamp frames. The frame bodies are made of soft material, and are respectively assembled on the passageways of the clamp frames. Each frame body includes an outer surface and an inner surface. A receiving slot is defined in the inner surface.

The slits are neighboring a user's temples, broadening side area of the lenses. Side areas of lenses are enlarged, allowing a user's eyes to reach side vision. When the swimming goggles are worn, the stems are located at about a user's ears, retaining the frame bodies and the lenses. Therefore the head strap is pulled in balance, avoiding the frame bodies inclined.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference toFIG. 1, swimming goggles1in accordance with the present invention comprise two clamp frames2, a connecting member3, two frame bodies4, two lenses5and pressing devices6. Each clamp frame2is made of hard material, and includes a first ring20and a second ring21corresponding to each other. A plurality of ribs22are spaced the same distance from each other and are parallel to each other for connecting the first ring20and the second ring21. A passageway23is defined between the first ring20and the second ring21for receiving the frame body4. Each clamp frame2has an assembling portion24on an inward side thereof for connecting with the connecting member3. A first arm281and a second arm282respectively extend from an outward side of the clamp frame2and are opposite to the assembling portion24. The first arm281and the second arm282extend toward each other to form a tapered portion28. A slit25is defined between the joint surfaces of the first arm281and the second arm282. Preferably, the slits25are inclined upwardly. A stem26extends unitarily from an end of the second arm282, and has appropriate length. The stem26has a distal portion261located near a user's ear when the swimming goggles are worn. An engaging portion27is unitarily formed at an end of the stem26. In this embodiment, the engaging portion is a ring button. In another embodiment, the engaging portion27may be a ring button, a strap buckle, or an assembly of a ring button and a strap buckle. A head strap (not shown) is assembled on the engaging portions27.

The assembling portions24are assembled with the connecting member3. The connecting member3forms positioning posts30on both sides thereof. Each of the positioning posts30has a T-shaped cross section. The assembling portions24define embedding grooves241for rotating to latch with the positioning posts30. The embedding grooves241are grooves with cross-like section. When assembled, the T-shaped positioning posts30fit to the assembling portions24, and rotate 90 degrees to latch with the assembling portions24.

The frame bodies4are made of soft material, and are respectively assembled on the passageways23of the mesh-like clamp frames2. Each frame body4includes an outer surface40and an inner surface41. A receiving slot42is defined in the inner surface41for receiving the lenses5. A plurality of positioning grooves43are defined in the outer surface41for corresponding to the ribs22of the clamp frames2. Each frame body4defines a latch groove44for locking rims of the first ring20and the second ring21. A pad45extends unitarily from a side of the inner surface41for touching a user's face comfortably.

Each pressing device6comprises an embedding portion60and a latch portion61locking with each other. The embedding portion60extends unitarily from an end of the first arm281and then inclines towards the latch portion61to form a projection (not labeled). The latch portion61extends unitarily from an end of the second arm282, and defines a locking groove (not labeled) for corresponding to the projection. The embedding portion60and the latch portion61shift the joint surfaces between the first arm281and the second arm282. The slit25shifts to between the embedding portion60and the latch portion61. In assembly, the projection of the embedding portion60locks and is joined with the locking groove of the latch portion61so as to close the slit25and urging to urge the first arm281and the second arm282to be assembled together. It is noted that the slit25is located adjacent a user's temple, and therefore, the lenses5have enlarged side area with either side of the clamp frame2being enlarged. Consequently, a user can have enlarged side visual field.

The slit25is further pressed, and the first arm281and the second arm282are assembled fixedly. Each pressing device6further comprises a pressing member62, and positioning protuberances63and orifices64engaging with each other. The pressing member62is hollow and tapered, and extends around the stem26to gradually press against the first arm281and the second arm282, thereby further pressing the slit25to close. The positioning protuberances63are formed on sides of the first arm281and the second arm282, respectively. The orifices64are formed on the pressing member62. When assembled, the positioning protuberances63and the orifices64engage with each other. The pressing member62is assembled on the first arm281and the second arm282, and reinforces assembly of the first arm281and the second arm282.

In assembly, the lenses5are respectively received in the receiving slots42of the frame bodies4. The frame bodies4are respectively assembled on the passageways23of the clamp frames2. During assembly, the ribs22of the clamp frames2slide into the positioning grooves43since the outer surfaces40of the frame bodies4are arcuate. The first ring20and the second ring21are embedded into the latch groove44of the frame bodies4. The frame bodies4and the lenses5are assembled onto the clamp frames2. As shown inFIGS. 2 and 3, the pressing devices6extend around the stems26, and press against the tapered portions28to urge the slits25to close. The positioning protuberances63and the orifices64engage with each other for assembling the pressing members60onto the tapered portions28, thereby reliably pressing the slits25to close.FIG. 4shows the swimming goggles of the present invention being assembled completely.

Further referring toFIGS. 5 and 6, in assembly, the frame bodies4and the lenses5are effectively clamped and pressed by the clamp frames2, the embedding portions60, the latch portions61, the pressing members60, the positioning protuberances63and the orifices64. When the swimming goggles are worn, the stems26are located at about a user's ears, like brackets of lenses, retaining the frame bodies4and the lenses5in the front. Two strips of a head strap (not labeled) are pulled in balance, avoiding the frame bodies4inclined. The slits25are neighboring a user's temples, broadening side area of the lenses5. Side areas of lenses are enlarged, allowing a user's eyes to reach side vision.
