Title: Swimming goggles

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to swimming goggles, and particularly to swimming goggles which have a left frame, a right frame and a connecting member integrally formed, and is used comfortably and easily. 
     2. Related Art 
     Swimming goggles are generally categorized as two types: separate type and integral type. The separate type has a separate connecting member connecting a left frame and a right frame together; while the integral type has a left frame and a right frame integrally formed with a connecting member. In order to receive lenses in the left frame and the right frame retentively, the integral type of swimming goggles ought to be made of rigid material, and otherwise the lenses can not be held. Due to restraint of the rigid material, pads on the left frame and the right frame fail to have flexibility to touch a user&#39;s face comfortably. Moreover, the connecting member made of rigid material is too stuff to suit for users with different face profiles. Lack of flexibility increases risk of water leakage arising from unclosed touch of the left and the right frames to a user&#39;s face. 
     In addition, due to restraint of the rigid material, buckles of the integral type of swimming goggles have to be designed simply for positioning a head strap and can not adjust the head strap finely. In use, the swimming goggles have to be adjusted repeatedly and inconveniently. 
     SUMMARY OF THE INVENTION 
     Accordingly, an object of the present invention is to provide swimming goggles which are used conveniently and worn comfortably without risk of water leakage and which prevents from deformation of frames while pulling a head strap thereof. 
     The swimming goggles comprise a left frame, a right frame and a connecting member integrally shaped, a pair of lenses, buckles and a nose support. The left frame and the right frame respectively form inward surfaces and outward surfaces. Passageways are respectively defined between the inward surfaces and the outward surfaces. Assembling holes are respectively defined in outward sides of the left frame and the right frame. The lenses are respectively received in the passageways, and respectively have first latches beside outward sides of the left frame and the right frame, and second latches beside inward sides of the left frame and the right frame. A plurality of injection holes is defined in peripherals of the lenses. The buckles are respectively assembled on the assembling holes. Each buckle includes a base with an extending hole defined in the base. A first embedding portion is defined in the base for mounting with the first latch. The nose support includes a middle portion, and second embedding portions on both sides of the middle portion for assembling with the second latches of the lenses. During manufacturing, the nose support, the buckles and the lenses are assembled together, and are then shaped with the left frame, the right frame and the connecting member when the left frame, the right frame and the connecting member are shaped integrally.

The left frame  20 , the right frame  21  and the connecting member  3  are made of Thermoplastic Rubber (TPR) which is featured of injection shaping and gluing. The left frame  20  and the right frame  21  respectively form inward surfaces  201 ,  211  and outward surfaces  202 ,  212 . Passageways  203 ,  213  are respectively defined between the inward surfaces  201 ,  211  and the outward surfaces  202 ,  212  for receiving the eyeglass  40 ,  41 . Assembling holes  204 ,  214  are respectively defined in outward sides of the left frame  20  and the right frame  21 . Pads  22  are respectively formed on the inward surfaces  201 ,  211 . The pads  22  are softer than the left frame  20  and the right frame  21  for touching a user&#39;s face comfortably. 
     The lenses  40 ,  41  are respectively received in the passageways  203 ,  213 . The eyeglass  40 ,  41  respectively form first latches  42  beside outward sides of the left frame  20  and the right frame  21 , and second latches  43  beside inward sides of the left frame  20  and the right frame  21 . According to one embodiment of the present invention, the first latches  42  and the second latches  43  respectively include a plurality of embedding holes in the lenses  40 ,  41 . A plurality of injection holes  401 ,  411  is defined in peripherals of the lenses  40 ,  41  for holding plastic when shaping. 
     The buckles  5  are assembled on the assembling holes  204 ,  214 . Each buckle  5  includes a base  50  consisting of a first plate  501  and a second plate  502 . The first plate  501  is slightly larger than the assembling hole  204 / 214  and is assembled on the inward surface  201 / 211  of the left frame  20 /the right frame  21 . The first plate  501  forms L-shaped bars  5021 ,  5031  symmetrical to each other, and a transverse bar  504  straddling on the L-shaped bars  5021 ,  5031 . An extending hole  505  is defined among the L-shaped bars  5021 ,  5031  and the transverse bar  504  for accommodating a head strap (not shown). The first plate  501  defines a first opening  51  at a side thereof. A first embedding portion  510  is defined on a peripheral of the first opening  51  for mounting with the first latch  42 . According to one embodiment of the present invention, the first embedding portion  510  includes three first positioning pegs on a peripheral of the first plate  501 . Positioning holes  511  are defined in a peripheral of the first opening  51 . An L-shaped flange  512  is defined along the peripheral of the first opening  51  for limiting movement of a button  53 . The button  53  is formed on an inward side of the first opening  51 . The button  53  is unitarily formed with the L-shaped flange  512  through a connecting bar  531  to comply with leverage principle. An abutting arm  54  (see  FIGS. 4 and 7 ) is formed near the extending hole  505 . In use, the button  53  is pressed downwardly, and the connecting bar  531  deforms. The abutting arm  54  is controlled to move forth and back by resiliency of the material. 
     The second plate  502  substantially has the same area as that of the assembling hole  204 / 214 , and is assembled on the assembling hole  204 / 214  and corresponding to the first plate  501 . A second opening  52  is defined corresponding to the first opening  51  of the first plate  501 . Positioning tabs  521  are formed on a peripheral of the second opening  52  for engaging with the positioning holes  511  of the first plate  501 . 
     The nose support  6  is made of Polypropylene (PP), Nylon, or the like. The nose support  6  is unitarily formed and is bent to fit for a user&#39;s nose profile. The nose support  6  is disposed between the lenses  40 ,  41  and includes a middle portion  60 , and second embedding portions  61  on both sides of the middle portion  60  for assembling with the second latches  43  of the lenses  40 ,  41 . According to one embodiment of the present invention, the second embedding portions  61  include second positioning pegs on both sides of the middle portion  60 . Through holes  62  are respectively defined in opposite sides of the middle portion  60  for stuffing plastic while shaping, thereby reinforcing assembly. 
     Referring to  FIGS. 1-6 , in assembly, the first embedding portions  510  of the buckles  5  engage with the first latches  42 , and the second embedding portions  61  of the nose support  6  engage with the second latches  43  of the lenses  40 ,  41 , thereby assembling the nose support  6  and the buckle  5  with the lenses  40 ,  41 . The left frame  20 , the right frame  21  and the connecting member  3  are integrally formed. As shown in  FIG. 2 , an outer layer of the swimming goggles is made of soft material, while the enwrapped buckles  5  and the nose support  6  are made of rigid material. Therefore, the pads  22  of the left frame  20  and the right frame  21  cover a user&#39;s eyehole softly. Furthermore, the nose support  6  is formed unitarily and covered by the connecting member  3 , and is bent to fit for a user&#39;s nose bridge. When the swimming goggles are worn, the nose support  6  touches a user&#39;s nose bridge closely. The buckles  5  are made of rigid material, and therefore pulling of the head strap will not result in deformation of the swimming goggles. Thus the swimming goggles are worn conveniently and comfortably, and guard against water leakage.
