Description

[Detailed Description of the Invention] This invention relates to a headphone band that connects headphones and is worn on the wearer's head to hold the headphones.

In order to hold the binaural headphones in their respective ear positions, a headphone band is used that is connected to these headphones and worn on the wearer's head.

A conventionally used headphone band is made of a band-shaped elastic body and has a structure in which headphones are attached to both ends of the band.

Therefore, it is not possible to adjust the position of the headphones according to the shape of the wearer's head, hairstyle, etc., which is inconvenient in use.

Furthermore, since it cannot be completely folded, it takes up a relatively large amount of space during storage and transportation, which increases costs during storage and transportation, and it is also inconvenient to carry.

The headphone band of this invention solves the various problems with conventional headphone bands, occupies a small space when stored, reduces costs during storage and transportation, and makes headphones extremely convenient to carry. It provides a band.

According to this invention, one end of each of the first and second end band pieces 11-2 and 11-3 is disposed on both ends of the central band piece 11-1 so as to be overlapped with each other.

These first and second end band pieces 11-2, 11-3
are both end portions of the central band piece 11-1, which are configured to be slidable along the extension direction as shown by the arrow X in FIG. 1, and overlapped with the central band piece 11-1 at the sliding end position. They are rotatably connected in the plane shown by arrows θ□ and θ2 in FIG. 1, respectively.

Hereinafter, the headphone band of this invention will be explained in detail based on its embodiments using the drawings.

Figure 1 shows a pair of headphones attached to the headphone band of this invention.
2-1.12-2 is attached, and this central band piece 1 is attached to both ends of the central band piece 11-1.
One end of each of the first and second end band pieces 11-2 and 11-3, which have the same length and width S as those of 1-1, are arranged in an overlapping manner.

Central band piece 11-1 and first end band piece 11-2, and central band piece 11-1 and second end band piece 11-3.
Since the structure of the overlapping arrangement portion is the same, the structure of the overlapping arrangement portion of the center band piece 11-1 and the first end band piece 11-2 will be described below.

Both edges of the central band piece 11-1 are cut out from its surface and steps 131, 132 are formed therein.

Furthermore, both ends of the central band piece 11-1 are cut off to be flush with the stepped portions 13-1 and 13-2 over a range slightly longer than the width of the band piece, thereby forming pivot surfaces 16-8 there.

Convex portion 14 that fits into this stepped portion 13-1.13-2
-1.14-2 are formed on both edges of the first end band piece 11-2, and the central band piece 11-1 and the first end band piece 11-2 are formed at the stepped portion 13-1. .13-2 and convex part 14
-1, 14-2 are fitted and attached respectively.

Central band piece 11-1, first and second end band pieces 11
-2.11-3 is made of, for example, an elastic resin material, and when all the band pieces are unfolded, the entire band is slightly curved to form an S゜circle.

Furthermore, a head pad 11-h made of, for example, urethane is attached to the inside of the central band piece 11-1 located on the wearer's head in order to soften the contact with the head when worn.

A guide groove 15 is formed in the center of the first end band piece 11-2 along the longitudinal direction, and the center band piece 11-1 and the first end band piece 11-2 are connected to each other in the guide groove 15. The width of the groove is widened at the end on the side, and an S-circular rotation hole 16 is formed there.

A guide groove 1 is formed approximately in the center of the rotation surface 16-8 at the end of the first end band piece 11-2 on the joint side of the central band piece 11-1.
An engaging column 17 having a diameter slightly smaller than the width of the central band piece 11-1 is formed to protrude at right angles to the surface of the central band piece 11-1.
is positioned to fit within the guide groove 15 of the first end band piece 11-2.

The cross section of the engaging column 17 may be an ellipse having a major axis in the length direction of the guide groove 15.

A first end band piece 11-2 is attached to the end of the first end pad piece 11-2 of this engaging column 17 on the side that protrudes from the guide groove 15.
A rectangular retaining plate 18 having a width equal to S is attached to the width of 2.

This retainer plate 18 is attached to the engagement post 17 so as to be able to slide smoothly on the first end band piece 11-2.

In this way, the stepped portion 13-1, 13-2 and the convex portion 14-1
．． 14-2, the central band piece 11-1 and the first
The end band piece 11-2 is slidably disposed along the direction of extension thereof.

Due to this sliding, the engaging column 17 of the central band piece 11-1 moves smoothly within the guide groove 15 of the first end band piece 11-2, and as a result, the retaining plate 18 moves smoothly into the first end band piece 11-2. Band piece 11
-2 Move by sliding on top.

Since the diameter of the engagement post 17 is set to be slightly smaller than the width of the guide groove 15, at the predetermined sliding position, the engagement post 17 maintains a pot shape fitted with the guide groove 15, and the first end The central band piece 11-2 is fixed to the central band piece 11-1 at a desired length adjustment position.

Therefore, by sliding the first end band piece 11-2 to a desired position with respect to the center band piece 11-1, the headphone 12 attached to the end of the first end band piece 11-2 -1 can be placed accurately at the ear position corresponding to each wearer.

At the end 1it of the first end band piece 11-2 opposite to the joining part with the center band piece 11-1, the headphones 12-1 are connected to each band piece through the supporting piece 20-1. It is configured to be rotatable around the end 11-t in a plane perpendicular to the plane of the circle.

Further, the headphones 12-1 are configured to be rotatable within the plane of a circle formed by each band piece, centering on the connecting portion of the support piece 20-1 with the headphones 12-1.

The center band piece 11 is located at one end position where the first end band piece 11-2 is slid with respect to the center band piece 11-1.
-1 retaining post 17 is located within the rotation hole 16 of the first end band piece 11-2.

In this state, the engagement post 17 is disengaged from the guide groove 15, and the first end band piece 11-2 is connected to the center band piece 1.
It is located on the rotating surface 16-8 of 1-1.

In this position, the stepped portion 13-1, 13-2 and the convex portion 1
4-1.14-2 is released, the center band piece 11-1 and the first end band piece 11-2 rotate around the engagement post 17 at the rotation hole 16. It becomes possible to move.

In this state, the first end band piece 1 is attached around the engaging post 17.
1-2 to overlap the first end band piece 11-2 with the center band piece 11-1.

When a similar operation is performed on the second end band piece 11-3, the entire headphone band to which the headphones 12-1, 12-2 are attached is folded as shown in FIG.

In this state, the space occupied by the entire headphone band to which the headphones are attached becomes extremely small, making it extremely convenient to store and transport.

As described above in detail, by using the headphone band of this invention, it is possible to fold the whole band into a storage state with the headphones attached, which greatly reduces the space occupied.

Therefore, it is very convenient to carry, and since the storage space can be reduced, the space occupied during transportation or storage can be reduced, and the cost required for this can be reduced.

Furthermore, the end band pieces to which the headphones are attached can smoothly slide against the center band piece, making it possible to easily achieve optimal wearing conditions depending on the wearer.
