However, the conventional foldable headphones described above have the following problems. That is, any of the headphones can be folded, for example, to be convenient for form and storage, but the operational feeling for the user is not reliable. In other words, when a user folds a foldable part or unfolds it for use, it is difficult to grasp how far each part that can be folded should be turned as an operation feeling, and there is no sense of security in operation. Conversely, being foldable, on the other hand, there is also a problem that, when used, the form expanded in the use state is difficult to stabilize, so that the feeling of wearing is poor. In addition, in the type as shown in FIGS. 16 and 17, it is necessary to use a connecting member for each connecting portion, so that there is a disadvantage that the number of parts increases, which leads to an increase in the number of manufacturing steps and an increase in cost.

[0037] From the state of FIG. 8, 9 and slider 10, it is rotated about the shaft body J ₂ as shown in FIG. 10, FIG. 11
Can be folded up to the headband member 30 side. When the slider 10 is rotated counterclockwise from the state shown in FIG. 8, first, the outer piece 14a and the inner piece 14b are bent so as to approach each other, and the click protrusions 16a, 1
6b escapes from the click grooves 36a, 36b. After that, when the holding portion 1 is turned to the state shown in FIGS.
The front surface portion 14c of the slider 4 comes into contact with the inner surface portion above the slider holding portion 34, and further rotation in the counterclockwise direction is restricted.

As will be described later, when the headphone 1 is folded, the state shown in FIG. 11 is obtained. Here, since the curvature of the headband 30 is larger than the curvature of the slider 10 (and the hanger 4), the main body 13 of the slider 10 is located on the upper surface side with respect to the headband 30 as seen from the left direction, as can be seen from FIG. Folded to be.

Conversely, when using the headphones 1, the headphone 1 is rotated so as to open from the state of FIG. 11 to the state of FIG. 8 after passing through the states of FIGS. 10 and 9, but at this time, as described above. Is click-engaged, a click feeling is obtained, and the user can feel a good operation feeling when opening the headphones 1.

Here, as described above, the inner surfaces of the outer wall portion 34a and the inner wall portion 34b are formed as the tapered surfaces TP, thereby preventing a click feeling from occurring in two stages. That is, when the slider 10 is rotated clockwise from the state shown in FIGS.
a and 16b enter the gap (slider mounting space 35) between the outer wall portion 34a and the inner wall portion 34b, and at this time, the click projections 16a and 16b are moved to the outer wall portion 34a.
12 and the inner surface of the inner wall portion 34b, there is a possibility that a click feeling may occur.
As shown in the H sectional view, it is avoided by the tapered surface TP, and it is possible to prevent the generation of a click feeling when rotated to the state of FIG.

When the slider 10 is rotated clockwise from FIG. 10 to FIG. 9, the click projections 16a and 16b are smoothly guided by the tapered surface TP and gradually become stronger. 34a, inner wall 34b
And the outer piece portion 14a and the inner piece portion 14b gradually bend so as to approach each other, so that a smooth turning operation feeling is obtained, and finally, the click projections 16a and 16b are formed. When the click grooves 36a and 36b are reached, the bending of the outer piece 14a and the inner piece 14b is eliminated,
A click feeling is obtained as described above.

The slit 15 in the held portion 14
Does not come off from the slider mounting space 35 in any of the rotational positions shown in FIGS.
This prevents the slit 15 from appearing on the appearance of the headphones 1 and impairing the appearance.

[0043] constructed as described above, so that the head band member 30 and the head band member 40 is shown in FIG. 1 omega _A
The headphone 1 of the present example, in which the slider 10 is rotatable in the ω _B direction, and the slider 10 is rotatable in the ω _B direction with respect to the headband member 40 and the slider 20 is Figure 1 shows the folding operation
3 and FIG.

The state of the headband members 30 and 40 shown by the dashed line in FIG. 13 corresponds to the case where the headband members 30 and 40 are turned to the most open state in the pivot 8, that is, the user Headphones 1 on head
It is in the state when wearing.

When the user removes the headphones 1, the weights of the headphone units 2 and 3 cause the headband members 30 and 40 to naturally move until the speaker surfaces of the headphone units 2 and 3 lightly abut as shown by the solid line in FIG. Is rotated.

When the user intends to fold the headphones 1, the user grasps the headphone units 2 and 3 with one hand from the state shown in FIG. One or both of 30 and 40 are grasped and rotated forward as shown by arrows T ₁ and T ₂ in FIG. That is, in the pivot portions 6, 7, the slider 10 and the headband member 3
0, the slider 20 and the headband member 40 are rotated from the state shown in FIG. 8 to the state shown in FIG.

When the pivots 6 and 7 rotate,
The headband member 30 and the headband member 40 are also rotated in the pivot portion 8 so as to be naturally closed, and when rotated to the state shown by the solid line in FIG. As shown in FIG. 14 (b), a completely folded state is obtained as shown in FIG.

At this time, as described above, the curvature of the headband 30 is larger than the curvatures of the slider 10 and the hanger 4, and therefore, when the headband 30 is completely folded, FIG.
The sliders 2 and 3 and the hangers 4 and 5 are folded so as to be located on the upper surface portions of the headbands 30 and 40 as shown in FIG. That is, the side of the front ends 31F of the headbands 30 and 40 close to the pivot 8 (that is, the front end 31F at the portion where the front and rear sizes are set large) collides with the hangers 4 and 5 or the headphone units 2 and 3 to be folded. It is not regulated.

As described above, in this example, after the headphone is removed, folding is completed with one touch while holding the headband. Moreover, in the folded state, the sound emitting surfaces of the headphone units 2 and 3 are folded inward facing each other, as can be seen from FIG. Can be

As understood from the above description,
Pivot portions 6, 7 and 8, the shaft J _1, the J ₂ bearing mechanism and the rotation range limiting mechanism is formed on the headband members 30, 40 and sliders 10 and 20 themselves, use a connecting member separate In this case, the number of parts can be reduced, and the efficiency of the manufacturing process and the cost can be reduced.

As described above, the headband members 30 and 40 can have a large size in the front and rear direction.
That is, when folded, as shown in FIG. 14B, the headband members 30 and 40 are folded so that the bottom sides face each other, and the headband member 30, the slider 10 and the hanger 4 are set to have different curvatures. Therefore, even if the headband members 30 and 40 take a large size in the front-back direction, they do not lead to a situation where the folding size is increased, and the degree of freedom of the shape of the headband members is greatly increased. Thereby, in this example, the feeling of wearing on the head can be improved, and the headband such as a skeleton can be eliminated as the design of the headphones 1.
And a good appearance can be obtained.

Further, in the pivot portions 6, 7, a click feeling is obtained by the click protrusions 16a, 16b and the click grooves 36a, 36b at the time of rotation, so that a good operation feeling is realized, and further, the click protrusions 16a, 16 16
b fits into the click grooves 36a and 36b,
The rotational position state is stably held. This also improves the feeling of wearing on the head during use. Slider 1
Due to the wavy portions 11 and 21 of the hangers 0 and 20 and the locking pieces KL of the hangers 4 and 5, a click feeling can be obtained stepwise even with respect to the relative sliding movement of the sliders 10 and 20 and the hangers 4 and 5. The operation feeling is improved, and the locking piece KL fits into the concave portion of the wavy portion 11, 21 at each slide position, so that the slide position is stably held, which also improves the wearing feeling of the headphones. Become.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made within the scope of the gist. For example, the shaft body J ₁ ,
The J _2, a protrusion in the axial direction depends on one member for coupling provided, by providing the fitting hole of the projection on the other member is fitted, may be each member is pivotally supported connected. That is, the shaft body is provided integrally with the head hand member or the slider.

[0054]

As can be seen from the above description, the headphone supporting device of the present invention gives a clicking feeling to the pivotal support of the unit holder and the headband when the headband is rotated with respect to the unit holder. Since the click mechanism is provided, the user can reliably and satisfactorily perform the operation of rotating the headband with respect to the unit holder. This click mechanism closes the unit holder.
Lick protrusion is formed on the headband side,
Taper that slides and guides the click projection when rotating for minutes
Surface and a click groove with which the click protrusion engages.
This configuration is preferable in that the number of components can be reduced without adding special components. further
When the click protrusion and the click groove are engaged, the rotation state of the headband and the unit holder can be regulated. For example, it is possible to prevent the headband from being unnecessarily rotated when using the headphones, thereby improving the wearing feeling. In addition, when rotating
Taper surface that guides the click projection by sliding contact
Does not cause a two-step click feeling
The click protrusion and the click groove engage with each other.
A smoother rotational operation feeling can be obtained.

Further, since the unit holder has a click mechanism that gives a click feeling when the hanger and the slider are relatively slid, the operation for extending and contracting in the longitudinal direction is more reliably performed by the click feeling. And there is an effect that it becomes simple. Furthermore, the click mechanism has a structure in which a plurality of uneven portions are formed on the slider along the longitudinal direction, and a locking piece is formed on the hanger, thereby reducing the number of parts without adding special parts. The effect can be obtained, and the slide movement can be restricted in a state where the locking piece is engaged with the concave and convex portion. Therefore, for example, it is possible to avoid inadvertent sliding when using headphones, thereby improving the wearing feeling.
