Description

Body length adjustment mechanism for face wear

The present invention relates to a belt length adjusting mechanism for a face wearing device, which is used for skiing, swimming, etc., goggles worn when riding a motorcycle, etc., to prevent dust. Various face wears including dust covers used for intrusion of harmful substances.

In the related art, a goggle is disclosed in Japanese Laid-Open Patent Publication No. 3142227. For example, as shown in Figs. 13 and 14, a pair of left and right belt bodies 12a are attached to the goggle body 11. 12b, each of the belt bodies 12a and 12b is provided with fixing bodies 13a and 13b which can adjust the length of the belt body. The fixed bodies 13a and 13b have an annular portion 16 through which the front ends of the tubular bodies 15a and 15b are formed, and a pair of extending portions 17a and 17b are attached thereto. Both sides of the annular portion 16 extend in the longitudinal direction of the belt; and the pair of locking portions 18a and 18b extend from the extending portions toward the width direction of the belt body; and the opening portion 19 is formed therein. Wait for the end of the locking portion.

In such a goggle, when the length of the belt body is adjusted, when one of the fixed bodies 13a is moved to an arbitrary position along one of the belt bodies 12a, the other belt body 12b is in a slack state. In this state, if the other fixed body 13b moves along the belt 12b, it becomes not slack, and the length of the belt body can be simply adjusted.

In the face wearer, a goggle is disclosed in Japanese Patent No. 4577547. For example, as shown in Fig. 15 and Fig. 16, the frame 21 is provided with a belt portion 22, and The casing 21 is provided with different individuals or an engaging portion 23 for engaging the belt portion 22 integrally. The plurality of protrusions 24 that are engaged with the engagement portion 23 are provided in the belt body portion 22. The engaging portion 23 is formed with an insertion hole 25 into which the belt portion 22 can be inserted, and an insertion groove 26 into which the projection portion 24 of the belt portion 22 can be fitted. Further, in the belt body portion 22, the protruding portion 24 is formed in the width direction of the belt body portion 22.

When the length of the belt body portion 22 is adjusted, the goggles can be released from the direction in which the projection portion 24 of the belt portion 22 inserted from the insertion hole 25 of the engaging portion 23 is disengaged from the fitting groove 26, thereby releasing the fixing state. Since the belt body portion 22 is moved, it is not necessary to wear as usual.

However, in the face wearing device as described above, although the length of the belt body is adjusted, it is easy to operate in a state where the face wearing device is detached from the face, but the face wearing device is worn on the face. Under, you can’t So easy to operate.

That is, in the face wearing device as described above, it is necessary to grasp the fixing body 13a, 13b or the engaging portion 23 with one hand, and grasp the belt body 12a, 12b or the belt body portion 22 with the other hand. Since the length of the belt body is adjusted, it is easy to operate while the face wearer is detached from the face. However, in the state where the face wearer is worn on the face, there is a problem that it is difficult to handle.

Further, in the above-described face wearing device, since the fixing body 13a is moved to an arbitrary position along the belt body 12a by intuition, the length of the belt body is adjusted, and there is a problem that the belt body length cannot be accurately adjusted. .

Further, in the above-described face wearing device, the plurality of protrusions 24 provided on the belt portion 22 must be sequentially engaged with the engaging portion 23, and the problem that the length of the belt body cannot be easily adjusted can be easily performed. .

Further, although the wire member 4 is not shown, it may be taken into the body 5a from the bottom of the body 5a of the two operating members 5 or released from the body 5a. Out. In this case, the through hole 6 is provided at the position of the outer structural member 3, and may be provided below the main body 5a of the operation member 5, so that one portion of the wire member 4 or the through hole 6 is not exposed to the foregoing. The front side of the outer structural member 3 is not conspicuous.

The belt length adjusting mechanism of the face wearing device of the present invention configured as described above can wear the face wearing device to the face when adjusting the length of the belt body in any of the embodiments shown in the drawings. In the state of the portion, the length of the wire 4 is adjusted by entraining or releasing the wire 4 by the operating member 5 located at the side or the head of the wearer, whereby the tape 2 can be pulled into the outer structure. The member 3 is attached or pulled out from the outer member 3.

Therefore, the belt length adjusting mechanism of the face wearing device of the present invention can of course easily adjust the length of the belt body in a state where the face wearing device is detached from the face, even if the face wearing device is worn. In the state of the face, the adjustment of the length of the belt can be easily performed.

Furthermore, the belt length adjusting mechanism of the face wearing device of the present invention is a pulley 8 of the operating member 5 located on the side head or the back head of the wearer in a state where the face wearing device is worn on the face. By rotating the knob 9 slowly, the wire 4 is slowly wound in or released to adjust the length of the wire 4, whereby the tape 2 can be slowly pulled into the outer structural member 3, Or pull out from the outer structural member 3.

Therefore, the belt length adjusting mechanism of the face wearing device of the present invention can of course simply adjust the length of the belt body and finely adjust the length of the belt body in a state where the face wearing device is detached from the face. , Even in the state where the face wear is worn on the face, the correct adjustment of the length of the tape and the fine adjustment of the length of the tape can be easily performed.
