BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connecting structure for a frame and a head strap of a pair of swimming/diving goggles. In particular, the present invention relates to a soft frame of a pair of swimming/diving goggles providing improved comfortable contact with the user's head, improved pull-resistance, and an aesthetically pleasing appearance.
2. Description of the Related Art
FIGS. 8 and 9 of the drawings illustrate a pair of conventional swimming/diving goggles including two rigid lenses 1′, two padding members 3′, and a head strap 2′. Each lens 1′ has a peripheral flanged portion 11′ on which an engaging portion 12′ is formed for engaging which an associated end of the head strap 2′. Each padding member 3′ is mounted to an inner side of an associated lens 1′. Each padding member 3′ is in intimate contact with an associated eye's socket of the user under the action of the clamping force of the head strap 2′. However, the peripheral flanged portion 11′ of the respective lens 1′ and the head strap 2′ are rigid and thus may cause injury to the user when impinged. Further, the peripheral flanged portion 11′ of the respective lens 1′ and the head strap 2′ provide poor comfortable contact with the user's head and poor feeling to touch.
FIGS. 10 and 11 illustrate another pair of conventional swimming/diving goggles including two rigid lenses 4′, a soft frame 5′, and a head strap 6′. The lenses 4′ are mounted to a front portion of the frame 5′. The frame 5′ has two sides 51′ each having an engaging portion 52′ for engaging with an associated end of the head strap 6′, with each engaging portion 52′ having a through-hole 521′ through which an associated end of the head strap 6′ extends. The sides 51′ of the soft frame 5′ provide improved comfortable contact with the head contour of the user than the pair of swimming/diving goggles of FIGS. 8 and 9. However, the pull-resistance is sacrificed. More specifically, as illustrated in FIG. 11, the engaging portions 52′ are apt to be largely deformed when subject to the force exerted to the engaging portions 52′ while pulling the head strap 6′. The distal portions 522′ of the engaging portions 52′ might even be broken.
FIG. 12 illustrates a portion of a further pair of conventional swimming/diving goggles including two rigid lenses 7′, a soft frame 8′, a head strap 9′ and two connecting blocks 91′. Formed on each of two sides of the frame 8′ is a connecting portion 81′ that has a through-hole 811′. Each connecting block 91′ is made of rigid material and has a width greater than that of an associated through-hole 811′. When the respective connecting block 91′ is pulled by the head strap 9′, the respective connecting block 91′ would not deform largely, preventing a distal portion 812′ of the respective engaging portion 81′ from being broken. However, the respective rigid connecting block 91′ is located outside the respective through-hole 811′ and thus fails to provide comfortable contact with the user's head. Further, the respective connecting block 91′ is not fixed before engaging with the head strap 9′ such that the respective connecting block 91′ is moved to a position (see the phantom lines shown in FIG. 12) away from the respective through-hole 811′, failing to provide an aesthetically pleasing appearance.
FIGS. 13 and 14 illustrate still another pair of conventional swimming/diving goggles including a frame 92′, two lenses 94′, and a padding member 95′. The frame 92′ includes a rigid inner frame 921′ embedded in a soft outer frame 922′. Each end of the head strap 93′ is engaged with an engaging portion 923′ on an associated side of the frame 92′. Thus, no deformation occurs in the rigid inner frame 921′ when the head strap 93′ is pulled. However, the rigid inner frame 921′ could not deform after formation, i.e., the rigid inner frame 921′ could not bend according to the head contour of the user, generating a gap “a” (FIG. 14) between the frame 92′ and the head of the user and failing to provide an intimate contact with the user's head.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a pair of swimming/diving goggles capable of providing improved comfortable contact with the user's head, improved pull-resistance, and an aesthetically pleasing appearance.
A pair of swimming/diving goggles in accordance with the present invention includes a soft frame having two outer sides each having an engaging portion, two lenses mounted in the soft frame, a head strap, and two connecting blocks respectively mounted to the engaging portions of the soft frame. Each connecting block is pull-resistant and includes a through-hole for engaging with the head strap. Each connecting block is at least partially embedded in and thus fixed by a plastic material for forming the soft frame.
In an embodiment of the invention, the respective connecting block is a ring or substantially C-shaped. The respective engaging portion of the soft frame is a ring at least partially embedded in the respective engaging portion of the soft frame.
The soft frame is bendable according to a head contour of a user, providing an intimate contact with two sides of the head of the user. The respective connecting block is not deformed when the head strap is pulled.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
