Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a composite lens for swimming or diving goggles with improved convenience to assembling procedure, improved water-resistance, and improved stability.

[0003] 2. Description of the Related Art

[0004] A pair of conventional goggles for swimming or diving includes at least one frame and a single lens held in each frame. The single lens provides only one optical function. To provide additional functions, a composite lens is provided in conventional swimming or diving goggles. FIG. 10 of the drawings illustrates a conventional composite lens comprised of a first lens 1′ and a second lens 2′ adhered to a side of the first lens 1′ by adhesive 3′. The first lens 1′ and the second lens 2′ are of different colors or have different functions such as filtration and polarization. However, the adhesive 3′ between the first lens 1′ and the second lens 2′ adversely affect the vision. Further, the adhesive 3′ deteriorates and thus adversely affects the transparency of the adhesive 3′. In some cases, the adhesive 3′ losses its adhesion and thus causes separation of the first lens 1′ and the second lens 2′. Further, as illustrated in FIGS. 11 and 12, since the first lens 1′ and the second lens 2′ are made from different materials, the amount of deformation of the first lens 1′ differs from that of the second lens 2′ when subject to external force or the ambient temperature changes, causing separation of the first lens 1′ and the second lens 2′. As a result, water is apt to enter the gap resulting from the separation and thus causes vague vision.

[0005] FIGS. 13 and 14 illustrate another conventional composite lens comprised of a first lens 4′ and a second lens 5′ that are made from different materials. The first lens 4′ includes a recessed portion 41′. The second lens 5′ is attached to a side of the first lens 4′. An ultrasonic welding procedure is carried out along a peripheral edge portion between the first lens 4′ and the second lens 5′ to thereby bond the first lens 4′ and the second lens 5′ together. The first lens 4′ further includes an outer flange 42′ to be inserted into a groove 61′ of a frame 6′. However, an ultrasonic welding procedure is required. Further, as shown in FIG. 15, the first lens 4′ and the second lens 5′ made from different materials tend to separate from each other at the joining area “a”. As a result, the vision is adversely affected, as water could enter the space between the first lens 4′ and the second lens 5′. Further, water is still apt to enter an interior of the frame 6′ via a jointing gap existed between the composite lens and the frame 6′, as the composite lens is only engaged with the groove 61′ of the frame 6′ by the outer flange 42′.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Referring to FIGS. 1 and 2, a composite lens 1 in accordance with the present invention generally comprises at least two lenses made from different materials. In a first embodiment shown in FIGS. 1 and 2, the composite lens 1 includes a first, outer lens 1 and a second, inner lens 12 that are overlapped one on the other. In formation, the first lens 11 and the second lens 12 are placed with an inner side 112 of the outer lens 11 being in face-to-face contact with an outer face 122 of the inner lens 12. The composite lens 1 is then placed into a mold (not shown). Plastic material is poured into the mold for forming a flexible frame 2 that includes an annular inner groove 20. An annular bottom wall 21 defining the annular inner groove 20 of the flexible frame 2 is bonded with a periphery 113 of the outer lens 11 and a periphery 123 of the inner lens 12. Further, an annular outer wall 22 defining the annular inner groove 20 of the flexible frame 2 is bonded with an outer annular edge portion 110 on an outer side 111 of the outer lens 11. Further, an annular inner wall 23 defining the annular inner groove 20 of the flexible frame 2 is bonded with an inner annular edge portion 120 on an inner side 121 of the inner lens 12. Thus, the composite lens 1 is bonded with the walls 21, 22 and 23 defining the inner groove 20 of the flexible frame 2 as an integral unit. The pair of goggles for swimming or diving thus formed provides good vision, as there is no adhesive between the outer lens 11 and the inner lens 12.

[0026] Referring to FIG. 3, since the outer lens 11 and the inner lens 12 constituting the composite lens 1 are made from different materials, the amount of deformation of the outer lens 11 differs from that of the inner lens 12. As a result, a gap is created between the outer lens 11 and the inner lens 12 when ambient temperature changes. Nevertheless, the composite lens 1 still provides a good vision, as there is no adhesive between the outer lens 11 and the inner lens 12. Further, the annular outer wall 22 defining the annular inner groove 20 of the flexible frame 2 is still bonded to the outer annular edge portion 110 on the outer side 111 of the outer lens 11, and the annular inner wall 23 defining the annular inner groove 20 of the flexible frame 2 is still bonded to the inner annular edge portion 120 on the inner side 121 of the inner lens 12. Thus, water leakage into the interior of the frame 2 is less likely to occur. An improved water resistance is thus provided.

[0027] FIG. 4 illustrates a second embodiment of the invention, wherein adhesive 3 may be applied to the periphery 113 of the outer lens 11, the periphery 123 of the inner lens 12, and an annular edge portion 15 between the outer lens 11 and the inner lens 12. The adhesive 3 increases the bonding force for the composite lens 1 and the frame 2 without adversely affecting the vision, as the adhesive 3 is not applied to a central portion between the outer lens 11 and the inner lens 12.

[0028] FIGS. 5 through 7 illustrates a third embodiment of the invention. In this embodiment, a composite lens 4 in accordance with the present invention includes a first, outer lens 41 and a second, inner lens 42 that is made from a material different from that for the outer lens 1. The outer lens 41 and the inner lens 42 are placed in a face-to-face manner as that in the first embodiment. A frame 5 includes an annular inner groove 51 for receiving the composite lens 4, with a periphery of the composite lens 4 being received in the annular inner groove 51 of the frame 5.

[0029] As illustrated in FIG. 7, the composite lens 4 and the frame 5 are placed into a mold (not shown), and plastic material is poured into the mold to form an integral padding member 6, with the padding member 6 being formed between the composite lens 4 and bonding with a periphery 413 of the outer lens 41 and a periphery 423 of the inner lens 42, an outer annular edge portion 410 on an outer side 411 of the outer lens 41, and an inner annular edge portion 420 on an inner side 421 of the inner lens 42. Thus, the composite lens 4 is integrally formed with the soft padding member 6. The pair of goggles for swimming or diving thus formed provides good vision, as there is no adhesive between the outer lens 41 and the inner lens 42. Even though ambient changes and thus causes deformation of the outer lens 41 and the inner lens 42 made from different materials, the soft padding member 6 is still reliably bonded to the outer lens 41 and the inner lens 42. An improved water resistance is thus improved. Further, the soft padding member 6 provides improved effect to absorb vibrations. Further, since the padding member 6 is integrally formed with the composite lens 4 and the frame 5, leakage of water into an interior of the frame 5 is less likely to occur.

[0030] FIG. 8 illustrates a fourth embodiment that is modified from the third embodiment. In this embodiment, the composite lens 4 includes an annular conic groove 43 in a periphery thereof. The material for forming the padding member 6 enters the annular conic groove 43 to increase the bonding strength and to further improve water resistance. The padding member 6 may envelope the frame 5 such that a stable, reliable engagement is provided between the padding member 6, the frame 5, and the composite lens 4.

[0031] FIG. 9 illustrates a fifth embodiment that is modified from the fourth embodiment of FIG. 8. In this embodiment, the frame consists of two frame halves 71 and 72. The composite lens 4 is mounted into a space between the frame halves 71 and 72, and plastic material is poured into the mold for forming a padding member 6, which is similar to that of the fourth embodiment of FIG. 8.

[0032] The composite lens 1, 4 may include more than two lenses without departing from the scope of the invention.

[0033] Although the invention has been explained in relation to its preferred embodiments, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
