Description: 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. DE29518493U discloses swimming goggles comprising a binding frame with a headband and frame units which secure left and right lens frame units by clasp units. 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 join 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. Thus viewed from one aspect the present invention provides a binding frame with left and right frame units and a nose bridge that joins said left and right frame units; at least one clasp unit on the left and right frame units and near the nose bridge; a lens frame unit comprising lens frames assembled on said left and right frame units and serving to accommodate lenses, said lens frame unit having clasp devices co-operating with said clasp units on the left and right frame units; a headband device located on the sides of the lens frame unit; wherein said clasp units comprise clasp grooves on the left and right frame units adjacent to the nose bridge, each clasp groove co-operating with a clasp post on the lens frame unit, characterised in that: on one side of said left and right frame units remote from the nose bridge and between the lens frames is an assembling device, said assembling device including: an assembling hole on each of the left and right frame units; a check unit on the lens frame unit adjacent to said assembling hole; a joining unit that passes through the assembling hole to engage with said check unit; and headband positioning grooves positioned on said joining units to assist assembling of the lens frame unit with the left and right frame units. The subject invention is characterized in that: the swimming goggles have a binding frame that is used for the assembly of the lens frame units. 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 lens frame unit corresponding to the clasp unit is a clasp device which secures the lens frame unit to the binding frame. The clasp unit has clasp grooves on the left and right frame units corresponding to the nose bridge. The clasp device is formed as a post on the lens frame unit. On one side of the left and right frame units, away from the nose bridge, and between the lens frame units is an assembling device. The assembling device includes assembling holes on the left and right frame units. A check unit on the lens frame unit corresponds to the assembling hole with a joining unit in contact with the check unit. On the joining unit are headband positioning grooves to enable assembling the lens frame unit with the left and right frame units. The assembling hole may comprise an opening facing from outside to the inside of the left and right frame units. The check unit may be a clasp tenon formed on the lens frame unit. The joining unit may be a first clasp arm and a second clasp arm formed on one side of a plate body and in contact with the clasp tenon. On the plate surface may be several grooves for the positioning of the headband. Fig. I is a perspective, disassembled view of the invention. Fig. 2 is a perspective, assembled view of the invention.
