Definitions

  • the present invention relates to a strap adjustment device, which is used to connect to a mask or a body of the mask of diving goggles or similar products, such as goggles, swimming goggles, protective goggles, or safety masks.
  • Apparatuses such as diving goggles, swimming goggles, protective goggles, or safety masks currently available on the market are often additionally equipped with an elastic strap to make the body of the mask fit to the face stably, and the elastic strap is most favored by consumers with the design of adjustable tightness.
  • the strap pulls the user's hair easily, especially when the regulating element for adjusting tightness of the elastic strap is placed at the joint between two sides of the strap and the body of the mask.
  • the hair is often accidentally caught in the regulating element when the mechanism of the regulating element is adjusted to open and close.
  • the regulating element which has a shape of a box and is arranged at the center of the strap, has become the best design style of the adjustable strap on the market because it avoids the above problems. Nevertheless, such a design requires a lot of components to be configured, which makes it difficult to reduce the material and assembly costs, and accordingly, the product price cannot be effectively controlled, so it is limited to be used in middle and high-end products only. Details will be further explained below.
  • the conventional goggles mask 1 comprises a body 11 of the mask, two straps 13, two sets of strap fastening components 15, and a regulating element 17, which is arranged in the center of the goggles mask 1.
  • the two straps 13 are respectively coupled to the left and right sides of the body 11 of the mask by two sets of strap fastening components 15, and the other free ends of the two straps 13 are respectively wound out through the regulating element 17.
  • the length of the straps 13 is adjusted by the engage/disengage mechanism of the regulating element 17.
  • Each set of strap fastening components 15 at least comprises components such as a convex buckle 151, a positioning plate 153, a pin 155, and a fixing ring 157.
  • the convex buckle 151 is used to snap connect the strap fastening components 15 to the body 11 of the mask, the elastic strap 13 is fixed by the positioning plate 153 after passing through the pin 155, and the end of the strap 13 is fixed by the fixing ring 157.
  • the components are complicated, the material and mold development costs are quite uneconomical, and the assembly requires more time and labor costs. Therefore, the product price cannot be lowered naturally. Besides, it also increases the cost and troubles of users.
  • An objective of the present invention is to provide a strap adjustment device with adjustable tightness for use in goggles, and users can change the tightness of the strap through the adjusting device arranged in the center of the strap. More importantly, through the simplified design of the whole components of the strap adjustment device, not only can the user's hair be prevented from getting tangled with the strap adjustment device, but also the need of the whole material and the assembly cost can be reduced. Therefore, the product price can be beneficial to consumers.

It shall also be noted that, the shapes of the distal ends of the first adjusting end portion 1033 and the second adjusting end portion 1051 are not limited to those described in this embodiment and the corresponding drawings, and other aspects shall be readily inferred by those of ordinary skill in the art.
  • the first female element 1031 of the first elastic strap 103 and the second female element of the second elastic strap 105 first respectively surround the first male element 101 and the second male element and are positioned on the first male element 101 and the second male element, and then the first adjusting end portion 1033 of the first elastic strap 103 and the second adjusting end portion 1051 of the second elastic strap 105 respectively pass through the regulating device 107.
  • the first adjusting end portion 1033 of the first elastic strap 103 and the second adjusting end portion 1051 of the second elastic strap 105 may also first pass through the regulating device 107 respectively, and then the first female element 1031 of the first elastic strap 103 and the second female element of the second elastic strap 105 respectively surround the first male element 101 and the second male element and are positioned on the first male element 101 and the second male element.
  • both the first elastic strap 103 and the second elastic strap 105 are made of flexible materials, while both the first male element 101 and the second male element are made of rigid materials.
  • the first elastic strap 103 and the second elastic strap 105 are made of a material having a Shore A hardness that is substantially not greater than 90.
  • the materials of the first elastic strap 103 and the second elastic strap 105 are preferably selected from materials such as silicone rubber, polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic rubber (TPR), thermoplastic polyurethane (TPU), rubber, or a combination thereof, but the present invention is not limited thereto, and other soft and elastic materials may also be applied to the first elastic strap and the second elastic strap of the present invention.
  • materials such as silicone rubber, polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic rubber (TPR), thermoplastic polyurethane (TPU), rubber, or a combination thereof, but the present invention is not limited thereto, and other soft and elastic materials may also be applied to the first elastic strap and the second elastic strap of the present invention.
  • the first male element 101 and the second male element which are respectively located on the first side 91 and the second side of the body 9 of the mask have a substantially same shape and are formed of a substantially same material.
  • the first elastic strap 103 and the second elastic strap 105 which are respectively located on the first side 91 and the second side of the body 9 of the mask have a substantially same length and are formed of a substantially same material. With the same configuration on the left and right sides, the manufacturing of components and the management of material and parts can be simplified.
  • the first male element 101 and the second male element of this embodiment are formed integrally with the body 9 of the mask.
  • the head portion 1011 of the first male element 101 protrudes out of the first elastic strap 103 for a height of at least 0.5 mm.
  • the second female element of the second elastic strap 105 surrounds the second male element from the head portion of the second male element and is positioned in the neck portion of the second male element, the head portion of the second male element protrudes out of the second elastic strap for a height of at least 0.5 mm. In this way, the connection between the male element and the elastic strap can be stabilized.
  • the present invention achieves the effect of simplifying the whole components of the strap adjustment device through the shape correspondence and opposite material hardness between the elastic strap and the female element or the male element arranged on the side of the body of the mask. Moreover, in the assembly process, it is unnecessary to put the strap through strap fastening components such as the convex buckle, the positioning plate, the pin, and the fixing ring one by one and then fix it on the regulating element like the case in the conventional goggle mask. In this way, the whole assembly process is simple, and the material, mold, and assembly costs of the product are reduced, thereby providing users with products of a higher cost performance, and improving the competitiveness of the products in the industry.
