Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to underwater goggles.

[Conventional technology]

Conventionally, in this type of underwater goggles, as shown in Fig. 5, for example, when the end of the connecting band is inserted into the inner diameter hole of the frame-shaped projection and released, the end of the connecting band rebounds. There are well-known devices that utilize the principle of locking the incisal edge of the inner diameter hole of the frame-like projection with force.

[Problem that the invention attempts to solve]

In the above-mentioned conventional device, for example, when the angle between the glasses component and the connecting band becomes as shown by the imaginary line in Fig. 4, the connecting band may naturally come off from the frame-shaped protrusion. In addition, the effective length of the connecting band changes when it is removed from the head, which often requires adjusting the length each time it is worn again. There were some flaws, such as the possibility that the above-mentioned effective length would fluctuate even while being worn.

[Means for Solving the Problems] The present invention provides underwater goggles having a structure in which the inner ends of a pair of eyeglass members are connected by a connecting band, in which a frame-like protrusion is also provided on the outer surface of the inner end of the eyeglass members. A locking pin is provided on the outer side of this frame-shaped projection, and a plurality of locking holes are provided at the ends of the connecting band, respectively, and the end of the connecting band is inserted into the inner diameter hole of the frame-shaped projection and locked. The above-mentioned defects are attempted to be solved by engaging the pin and the locking hole.

〔Example〕

In the first embodiment of the present invention shown in FIGS. 1 and 2, a pair of eyeglass structures 1 and 1' each having a size that covers one eye is molded from a transparent hard synthetic resin material. Elongated holes 2, 2' are provided at the outer ends of the molding bodies, and frame-shaped projections 3, 3' are formed on the outer surface of the inner end thereof during the above-mentioned molding process. A locking pin 4 is provided protruding from the inner edge of the central portion, and rubber border members 5, 5' are attached to the outer periphery of each eyeglass component 1, 1', and a Cushion members 6 and 6' made of sponge are pasted, and a connecting band 10 is separately made of a soft synthetic resin material and has a stopper 8 at the base end and a plurality of locking holes 9 at the tip end. Then, this connecting band 10 is inserted into the frame-shaped projection 3 of one of the eyeglass components 1, and the stopper 8 is locked to the edge of the inner diameter hole 11 of the frame-shaped projection 3, and the tip of the connecting band 10 is inserted. is inserted into the frame-shaped projection 3' of the other eyeglass component 1', and the locking hole 9 and the locking pin 4 are engaged with each other.

In addition, in the second embodiment shown in FIG.
A locking hole 9 is provided at both ends of the connecting band 10, and both ends of the connecting band 10 are fixed with locking pins 4, and a third embodiment shown in FIG. In this example, both ends of the connecting band 10 are locked inside the frame-like projections 3, 3'.

In addition, 13 in the figure is a retractable headband, 14
15 indicates a retaining member, and 15 indicates a through hole.

[Effect]

As described above, the present invention has a structure in which the tip of the connecting band is inserted into the inner diameter hole of the frame-shaped projection and engaged with the locking pin through the locking hole. The tip of the band is less likely to come off naturally than the frame-like protrusion, and the effective length will not fluctuate.

[Effect of idea]

Since the present invention is as described above, it has excellent effects that can fully achieve the intended purpose.
