Eyewear mounting device

Abstract

In an eyewear mounting device, a pressing surface portion is formed at an end of a frame, a pair of supporting arms is provided on the pressing surface portion at an interval, a shaft around which a tightening band is wound is provided between tips of the supporting arms. An operating member rotationally attached between the supporting arms has a pressing operation portion, a pulling-up operation portion, an elastic piece and an engaging claw. The engaging claw is engageable with any of a plurality of protruding portions provided in a longitudinal direction of a surface side of the tightening band. This configuration results in easy operation of the operating member in the state where the eyewear mounting device is worn on the face. Further, only one operating member is used as the component member, thus resulting in easy assembly of the eyewear mounting device.

Description

technical field [0001] The present invention relates to various face wearing devices for goggles, glasses, masks and the like with fastening straps. Background technique [0002] In the past, as this facial wearing device, for example, as disclosed in the Japanese Patent Publication No. 59-25414, there are Figure 5 , 6 Goggles shown. In this swimming goggle, the plates 23a, 23b are arranged at approximately the center of each of the side portions 22a, 22b of the eyeglass main body 21 at intervals of about a width. Further, a belt threading opening 24a is formed in the back plate 24 connecting the above-mentioned plates 23a and 23b, through which the fastening belt 25 having protrusions 25a intermittently formed over the entire width direction is passed. Moreover, the mounting piece 27 is rotatably supported on the shaft 26 pivotally mounted between the above-mentioned plates 23a and 23b, and the above-mentioned mounting piece 27 is biased by a spring 28 so that it is alwa...

AI Technical Summary

Problems solved by technology

[0010] However, the above Figure 5 , 6 In order to loosen the fastening belt 25 in the conventional face wearing tool shown, it is necessary to press down the pressing part 29 of the mounting piece 27 to compress the spring 28. In order to press down the vicinity of the upper part of the spring 28, it needs to be pressed strongly. Problems that are difficult to operate in the state on the face

[0011] And above-mentioned conventional facial wearing tool wants to loosen fastening belt 25 then only needs to carry out the operation of pressing down the upper part of spring 28 and gets final product, but under the state that is worn on the face, only press down the upper part of above-mentioned spring 28 In such an operation nearby, the operation is sometimes difficult to perform, and there is a problem of inconvenience

[0012] In addition, the above-mentioned conventional face wearing device is composed of two parts, the mounting piece 27 and the spring 28, as the structural members for loosening the fastening belt 25, and the number of parts is many, and there is a problem that assembly is difficult.

[0013] and the above Figure 7~9 The conventional face wearing device shown has a structure in which the fastening belt 34 is loosened by sliding the operating member 35, but the finger tends to slip during the sliding operation, and there is a problem that it is difficult to operate while wearing it on the face.

[0014] Moreover, the above-mentioned conventional face wearing tool only needs to operate to slide the operation member 35 to loosen the fastening belt 34, but in the state worn on the face, only the operation to slide the above-mentioned operation member 35 is performed. , sometimes this operation is difficult to carry out, having the problem of inconvenient

[0015] In addition, in the above-mentioned conventional face wearing tool, also as a constituent member for loosening the fastening belt 34, it is composed of two parts, the buckle 33 and the operation member 35. Figure 5 , 6 The face wearing device shown in the figure also has a large number of parts and has a problem of difficulty in assembling
