ABSTRACT:
FIELD OF THE INVENTION
The subject invention relates to a type of swimming goggles, particularly to one with a nose bridge involving flexible frames and clasp pieces to combine left and right lens frames.
BACKGROUND OF THE INVENTION
There are different ways to join the lens frames of swimming goggles, which can be grouped into two categories: one is a monobloc lens frame form, protective pads and the nose bridge, the other involves fastening the left and right lens frames using a nose bridge. The monobloc type of nose bridge is a simple type that does not allow adjustment. This nose bridge specification will suit the general consumer public. The fastening type allows multiple-step adjustment. The consumer can make proper adjustment to suit the span between the user's eyes. Both types have their market share, and their respective advantages and disadvantages in production. Basically, therefore, the development and improvement of the monobloc type and the fastening type are designed separately.
However, the monobloc type of swimming goggles that are easy to use without the need for adjustment has become the mainstream in appeal and design. The conventional monobloc type of swimming goggles is generally made from hard resin (polycarbonate resin), in which entire frame body is rigid without flexibility, so it only suits users with a specific face shape. As a result, another conventional design has been developed which uses soft resin to shape the lens frames, nose bridge and protective pads as one monobloc. The nose bridge serves the concurrent purposes of joining the two frames and providing proper flexibility and avoiding deformation of the frame body due to the lens accommodation. This lens type cannot withstand the pulling force of the headband, and special consideration must be paid to the construction of the swimming goggles, such as: reinforced strength design for the nose bridge, or reinforced strength against frame body deformation, so that the frame body will not be deformed.
BRIEF DESCRIPTION OF THE INVENTION
The objective of the subject invention is to provide a new swimming goggle construction with an innovative design that can be conveniently assembled and comfortably worn by the user. Said swimming goggles provide twin frames made from a flexible material to joint the frames. Thus, the twin frames can be separately considered in terms of design and suitable material selection. Considerations can be taken to require the nose bridge to be equipped with adequate tensile strength, to provide a monobloc type exterior configuration and fastening assembly style.
The subject invention is characterized in that: the swimming goggles have a binding frame that is used for the assembly of the main lens frame. The binding frame includes the left and right frame units and a nose bridge linking the left and right frame units. On the left and right frame units near the nose bridge is a clasp unit. On the main frame unit corresponding to the clasp unit is a clasp piece, thereby secures the main frame unit to the binding frame.
As mentioned in the above characteristics, the clasp unit has clasp grooves on the left and right frame units corresponding to the nose bridge. The clasp piece is formed as a post on the main frame unit.
Another characteristic of the subject invention is that, on one side of the left and right frame units, away from the nose bridge, and between the main frame units is an assembling device. The assembling device includes assembling grooves on the left and right frame units. A check unit on the main frame unit corresponds to the assembling groove with a joining unit in contact with the check unit. On the joining unit are headband positioning grooves to enable assembling the main frame unit with the left and right frame units.
The assembling groove is an opening facing from outside to the inside of the left and right frames. The check unit is a clasp piece formed on the main frame unit. The joining unit refers to a first clasp arm and a second clasp arm formed on one side of a plate body and in contact with the clasp piece. On the plate surface are several grooves for the positioning of the headband.
